Abstract

The present invention relates to the technical field of wireless communications, and in particular to a method and device for resource configuration and data transmission, and is used for solving the problem in the prior art that a transmission time delay is too long due to the fact that an existing LTE D2D technique only supports transmission between pieces of user equipment in a broadcast manner and a resource configuration process is independent from a data transmission process. In the embodiments of the present invention, a network control device determines each device involved in transmission in the same region, and determines a transmission resource used by each device for transmission, and performs transmission resource configuration. Since a network control device can perform resource configuration on each device involved in transmission in the same region, it is unnecessary to configure a control resource for a sending end, and it is also unnecessary for the sending end to notify a receiving end of a specific resource sending position before sending data, so that a resource configuration solution is optimized, and the resource configuration is more compact. Therefore, the resource configuration solution, compared with an LTE D2D transmission solution, can greatly reduce a time delay.

In this application.

技术领域Technical field

本发明涉及无线通信技术领域，特别涉及一种资源配置和数据传输的方法及设备。The present invention relates to the field of wireless communication technologies, and in particular, to a resource configuration and data transmission method and device.

背景技术Background technique

未来动态自组织网络将广泛应用于工业自动化，车辆自动编队驾驶等方面，无线资源配置与传输方案是保证动态自组织网络提供低时延高可靠传输服务的关键。Future dynamic self-organizing networks will be widely used in industrial automation, vehicle automatic formation driving, etc. The wireless resource configuration and transmission scheme is the key to ensure that the dynamic self-organizing network provides low-latency and high-reliability transmission services.

目前LTE(Long Term Evolution，长期演进)D2D(设备到设备)技术仅支持用户设备间广播方式的传输，用户设备间如果有数据需要传输，发送端需要向基站申请资源，基站会给发送端分配传输资源以及控制资源，发送端需要先通过控制资源通知接收端传输资源的位置，然后再发送数据，由于资源配置过程和数据传输过程的相对独立，导致传输时延过长。Currently, the LTE (Long Term Evolution) D2D (device-to-device) technology only supports the transmission of broadcast mode between user equipments. If data needs to be transmitted between user equipments, the sender needs to apply for resources to the base station, and the base station allocates the resources to the sender. To transmit resources and control resources, the transmitting end needs to notify the receiving end of the location of the transmission resource through the control resource, and then send the data. Due to the relative independence of the resource configuration process and the data transmission process, the transmission delay is too long.

综上所述，LTE D2D技术仅支持用户设备间广播方式的传输，而资源配置过程和数据传输过程的相对独立，导致传输时延过长。In summary, the LTE D2D technology only supports the transmission mode between user equipments, and the resource configuration process and the data transmission process are relatively independent, resulting in a long transmission delay.

The cluster head is responsible for coordinating the radio resources in the data transmission process of the cluster area.

在接入层控制面方面EP(末端节点)类型用户设备可以被配置为“簇头模式”，当EP类型用户设备以“簇头模式“工作时，簇头用户设备需要对簇内区域进行同步和资源配置等方面的协调，并负责对非接入层的控制信息进行广播。The EP (end node) type user equipment can be configured as a "cluster head mode" in the access layer control plane. When the EP type user equipment works in the "cluster head mode", the cluster head user equipment needs to synchronize the intra-cluster area. Coordination with resource configuration and other aspects, and is responsible for broadcasting control information of non-access stratum.

如果应用场景是动态自组织网络，则网络控制设备为簇头节点；网络接入设备为末端节点，同一个区域就是簇头节点和末端节点所在的同一个簇，具体可以参见图1B。If the application scenario is a dynamic ad hoc network, the network control device is a cluster head node; the network access device is an end node, and the same region is the same cluster where the cluster head node and the end node are located. For details, refer to FIG. 1B.

如果应用场景是蜂窝网络，可以将“控制器”和“传输功能”合并，这样网络控制设备可以是“控制器”和“传输功能”合并的基站类型设备，比如宏基站、家庭基站；网络接入设备为用户设备(User Equipment，UE)，同一个区域就是基站和接入该基站的用户设备组成的区域，具体可以参见图1C。If the application scenario is a cellular network, the "controller" and the "transport function" may be combined, such that the network control device may be a base station type device in which the "controller" and the "transport function" are combined, such as a macro base station and a home base station; The inbound device is a user equipment (User Equipment, UE), and the same area is an area formed by the base station and the user equipment accessing the base station. For details, refer to FIG. 1C.

还可以将“控制器”和“传输功能”分离，这样网络控制设备可以是数据中心类型设备，“传输功能”可以是“接入点”功能设备(这里的“接入点”功能设备具有类似于基站的射频拉远的RRH部分的功能)；网络接入设备为用户设备(UE)，同一个区域就是基站和接入该基站的用户设备组成的区域。It is also possible to separate the "controller" and the "transport function" so that the network control device can be a data center type device, and the "transport function" can be an "access point" function device (here, the "access point" function device has a similar The function of the RRH part of the remote radio frequency of the base station; the network access device is a user equipment (UE), and the same area is an area composed of the base station and the user equipment accessing the base station.

不同于传统蜂窝网络中Access Link(接入链路，用户设备与基站之间通信链路)，以及Side link(用户设备之间直接通信链路)采用相互独立的传输方案设计，因此导致时延过长以及用户设备物理层复杂度高的问题(用户设备在Access Link和Side link需要采用两套独立的物理层处理链)。Different from traditional cellular networks, Access Link (access link, communication link between user equipment and base station), and Side link (direct communication link between user equipments) are designed with independent transmission schemes, thus causing delay The problem is that the user equipment is too complex and the physical layer of the user equipment is high (the user equipment needs to adopt two independent physical layer processing chains in Access Link and Side Link).

本发明实施例在网络接入设备与网络控制设备，以及网络接入设备与网络接入设备之间的通信采用统一的传输方案设计，因此可以很好的控制时延。进一步还可以很好的降低设备物理层实现复杂度，降低网络接入设备和网络控制设备的实现成本。In the embodiment of the present invention, the communication between the network access device and the network control device, and the network access device and the network access device is designed by using a unified transmission scheme, so that the delay can be well controlled. Further, the complexity of the physical layer implementation of the device can be well reduced, and the implementation cost of the network access device and the network control device can be reduced.

本发明实施例中沿用基于中心调度方式下的无线资源分配方案，并由网络控制设备对区域内的数据传输进行传输资源的配置。对于网络接入设备之间直接传输的情况，网络控制设备将针对特定传输的无线资源同时配置给发送端和接收端，因此与LTE D2D传输方案相比可大大降低时延。In the embodiment of the present invention, a radio resource allocation scheme based on a central scheduling mode is used, and is controlled by a network control device. The data transmission in the area is configured for transmission resources. For the case of direct transmission between network access devices, the network control device configures the specific transmitted radio resources to the transmitting end and the receiving end at the same time, so the delay can be greatly reduced compared with the LTE D2D transmission scheme.

本发明实施例对于网络接入设备到网络接入设备的多跳传输，可以对每跳进行单独传输资源配置，以及为多跳进行联合资源配置。In the embodiment of the present invention, for multi-hop transmission from a network access device to a network access device, a separate transmission resource configuration may be performed for each hop, and a joint resource configuration may be performed for multiple hops.

下面结合说明书附图对本发明实施例作进一步详细描述。The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

如图2所示，本发明实施例数据传输的***包括：网络控制设备10和多个网络接入设备20。As shown in FIG. 2, the system for data transmission in the embodiment of the present invention includes: a network control device 10 and a plurality of network access devices 20.

在实施中，如果一个网络接入设备需要发送数据，需要向网络控制设备申请传输资源。In an implementation, if a network access device needs to send data, it needs to apply for transmission resources to the network control device.

可选的，网络控制设备可以为网络接入设备分配专用的调度请求发送资源；也可以配置一个调度请求发送资源池，由网络接入设备通过抢占方式获取资源。Optionally, the network control device may allocate a dedicated scheduling request to the network access device to send the resource, or configure a scheduling request to send the resource pool, and the network access device acquires the resource by using the preemptive mode.

对于网络接入设备，如果网络控制设备为自己配置专用的调度请求发送资源，则网络接入设备在有数据需要发送时，可以通过专用的调度请求发送资源向网络控制设备申请传输资源；For the network access device, if the network control device configures a dedicated scheduling request transmission resource for itself, the network access device may apply for transmission resources to the network control device through a dedicated scheduling request sending resource when there is data to be sent;

如果网络控制设备没有为自己配置专用的调度请求发送资源，则网络接入设备在有数据需要发送时，可以通过调度请求发送资源池进行抢占，在抢占到资源后通过抢占的资源向网络控制设备申请传输资源。If the network control device does not configure a dedicated scheduling request to send resources for itself, the network access device may send a resource pool for preemption by scheduling a request when the data needs to be sent, and the network control device passes the preempted resource after the resource is preempted. Apply for transmission resources.

在实施中，如果网络接入设备通过专用的调度请求发送资源向网络控制设备申请传输资源，可以不在调度请求中携带网络接入设备的设备标识；In an implementation, if the network access device requests the transmission resource from the network control device by using the dedicated scheduling request sending resource, the device identifier of the network access device may not be carried in the scheduling request;

相应的，网络控制设备根据承载调度请求的调度请求资源的位置，确定对应的网络接入设备。Correspondingly, the network control device determines the corresponding network access device according to the location of the resource requesting the scheduling request requesting resource.

可选的，有可能网络接入设备同时激活针对不同目标的并行会话，则网络接入设备还可以将会话标识(或称为通信组标识)替换上述的设备标识，并将会话标识置于调度请求中。Optionally, it is possible that the network access device simultaneously activates the parallel session for different targets, and the network access device may further replace the session identifier (or the communication group identifier) with the device identifier, and place the session identifier in the scheduling. Requested.

网络控制设备在为进行传输涉及的各设备配置传输资源时，可以根据当前子帧中的资源进行配置。When the network control device configures transmission resources for each device involved in the transmission, it can be configured according to the resources in the current subframe.

具体的，若当前子帧的资源能够满足进行传输使用的传输资源，则所述网络控制设备从当前子帧的资源中确定各设备进行传输使用的传输资源；Specifically, if the resource of the current subframe can meet the transmission resource used for transmission, the network control device determines, from the resources of the current subframe, the transmission resource used by each device for transmission;

如果进行传输的业务为周期性业务，则所述网络控制设备可以分别在每个周期开始前确定下个周期的传输资源。If the service to be transmitted is a periodic service, the network control device may determine the transmission resources of the next cycle before starting each cycle.

可选的，所述网络控制设备可以确定每个周期进行传输使用的传输资源；Optionally, the network control device may determine a transmission resource used for transmission in each period;

这样所述网络控制设备配置确定的每个周期进行传输使用的传输资源，也就是说网络控制设备将每个周期使用的传输资源一次配置给各设备； The network control device configures the transmission resource used for transmission in each cycle determined by the network control device, that is, the network control device configures the transmission resource used in each cycle to each device at a time;

相应的，若进行传输的业务为周期性业务，则所述网络接入设备确定所述处于同一区域中的网络控制设备配置的每个周期进行传输使用的传输资源，后续周期开始后就不需要再向网络控制设备请求传输资源。Correspondingly, if the service to be transmitted is a periodic service, the network access device determines the transmission resource used for transmission in each period of the network control device configuration in the same area, and does not need to be performed after the subsequent period starts. Then request the transmission resource from the network control device.

在配置传输资源时，所述网络控制设备可以通过单播或广播方式进行传输资源配置。When configuring the transmission resource, the network control device may perform transmission resource configuration by using unicast or broadcast mode.

可选的，网络控制设备可以在发送一次配置信息时，携带多个传输需要的传输资源，并用设备标识和/或会话标识进行区分；Optionally, the network control device may carry multiple transmission resources required for transmission when sending the configuration information once, and distinguish the device identifier and/or the session identifier.

相应的，网络接入设备可以根据自身保存的设备标识和/或会话标识，确定收到的配置信息中是否有与自身相关的配置。Correspondingly, the network access device can determine, according to the device identifier and/or the session identifier saved by itself, whether the received configuration information has a configuration related to itself.

可选的，所述网络接入设备在发送调度请求后，若在设定时长内未收到所述网络控制设备为所述网络接入设备配置的传输资源，则可以重新向所述网络控制设备发送调度请求。Optionally, after the network access device sends the scheduling request, if the network control device does not receive the transmission resource configured by the network control device for the network access device, the network access device may re-control the network. The device sends a scheduling request.

这里所述网络控制设备为中继端，则需要根据调制编码方式，通过配置的传输资源接收包含数据包的数据块，接收使用的调制编码方式如果是非固定的，则需要从传输块的控制部分中确定调制编码方式，根据调制编码方式对后续的数据包进行接收处理；Here, the network control device is a relay end, and the data block including the data packet needs to be received through the configured transmission resource according to the modulation and coding mode, and if the modulation coding mode used for receiving is not fixed, the control part of the transmission block is required. Determining a modulation and coding mode, and performing reception processing on subsequent data packets according to a modulation and coding manner;

在接收到数据包后，需要将接收到的数据包封装成用于物理层传输的传输块，如果调制编码方式是非固定，还需要在传输块的控制部分中增加调制编码方式。After receiving the data packet, the received data packet needs to be encapsulated into a transport block for physical layer transmission. If the modulation and coding mode is non-fixed, it is also necessary to add a modulation and coding mode in the control part of the transport block.

其中，接收使用的调制编码方式和发送使用的调制编码方式可以相同，也可以不同。The modulation and coding scheme used for reception and the modulation and coding scheme used for transmission may be the same or different.

若所述网络接入设备为接收端，则所述网络接入设备根据调制编码方式，通过配置的传输资源接收包含数据包的数据块；其中若调制编码方式是非固定，则所述传输块的控制部分中包括调制编码方式；或If the network access device is a receiving end, the network access device receives a data block including a data packet through a configured transmission resource according to a modulation and coding manner; wherein if the modulation and coding mode is non-fixed, the transmission block is Control Part includes modulation coding; or

这里所述网络接入设备为中继端，则需要根据调制编码方式，通过配置的传输资源接收包含数据包的数据块，接收使用的调制编码方式如果是非固定的，则需要从传输块的控制部分中确定调制编码方式，根据调制编码方式对后续的数据包进行接收处理；Here, the network access device is a relay end, and the data block including the data packet needs to be received through the configured transmission resource according to the modulation and coding mode, and if the modulation coding mode used for receiving is not fixed, the control of the transport block is required. The modulation coding mode is determined in the part, and the subsequent data packet is received and processed according to the modulation and coding mode;

本发明实施例调制编码方式可以是固定方式，即双方约定好后不再变化；也可以是非固定方式(可以变动)，即双方不进行约定，这样就需要发送端在发送时在数据块最前面加入本次的调制编码方式，这样接收端在数据块最前面确定调制编码方式后，就可以根据确定的调制编码方式对数据块中的数据部分进行接收。In the embodiment of the present invention, the modulation and coding mode may be a fixed mode, that is, the two parties do not change after the agreement is made; or the non-fixed mode (can be changed), that is, the two parties do not make an agreement, so that the sender needs to be at the front of the data block when transmitting. The modulation coding mode is added, so that after the receiving end determines the modulation and coding mode at the forefront of the data block, the data portion in the data block can be received according to the determined modulation and coding mode.

如果涉及到多跳设备，则中继设备(即多条中间的设备统称)既要确定接收时的传输资源，还要确定发送时的传输资源。对于网络控制设备也会为多跳设备分配收时的传输资源和发送时的传输资源。If a multi-hop device is involved, the relay device (ie, a plurality of intermediate devices collectively) must determine the transmission resource at the time of reception, and also determine the transmission resource at the time of transmission. For the network control device, the multi-hop device is also allocated the transmission resource at the time of transmission and the transmission resource at the time of transmission.

在实施中，有可能涉及到传输的设备无法进行传输，比如关闭或从区域中移动等情况，这时如果已分配的传输资源如果还未使用，则可以释放这部分资源。比如周期性业务或者非周期性业务但是分配后还未传输。In the implementation, it may be involved in the transmission of the device can not be transmitted, such as shutting down or moving from the area, etc., if the allocated transmission resources, if not already used, can release these resources. For example, periodic service or non-cyclical service but not transmitted after allocation.

如果网络接入设备检测到去激活事件发生，且配置的传输资源中有未使用的传输资源，则释放已配置的传输资源，并通知所述网络控制设备。If the network access device detects that a deactivation event occurs and there are unused transmission resources in the configured transmission resource, the configured transmission resource is released, and the network control device is notified.

这里任何无法进行传输的情况都可以作为去激活事件。Anything that cannot be transferred here can be used as a deactivation event.

相应的，所述网络控制设备在确定进行传输涉及的各设备中有发生去激活事件的节点后，通知其他节点释放已配置的传输资源以及与传输相关的上下文信息。Correspondingly, after determining that the node involved in the transmission has a node in which the deactivation event occurs, the network control device notifies other nodes to release the configured transmission resource and the context information related to the transmission.

下面以本发明应用于动态自组织网络和蜂窝网络(其中，蜂窝网络中将“控制器”和“传输功能”合并)为例进行说明，应用于其他网络中只是与应用于动态自组织网络中的各实体的名称不同，具体过程一样，在此不再赘述。In the following, the present invention is applied to a dynamic ad hoc network and a cellular network (in which a "controller" and a "transport function" are merged in a cellular network) as an example, and is applied to other networks only in a dynamic self-organizing network. The names of the entities are different, and the specific process is the same, and will not be repeated here.

一、应用于动态自组织网络First, applied to dynamic self-organizing network

场景一、EP(末端节点)到EP的单跳传输过程Scene 1, single-hop transmission process from EP (end node) to EP

针对EP到EP传输的动态调度方案，主要满足突发性业务的传输要求。The dynamic scheduling scheme for EP to EP transmission mainly meets the transmission requirements of bursty services.

如图9所示，本发明实施例动态自组织网络中EP到EP的单跳传输包括：As shown in FIG. 9, the single-hop transmission of EP to EP in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：数据包在到达发送端EP后，发送端EP向CH(簇头节点)请求无线资源配置。Step 1: After the data packet arrives at the transmitting end EP, the transmitting end EP requests the radio resource configuration from the CH (cluster head node).

可选的，在簇区域内接入末端节点EP数量较少的情况下，CH可以预先为EP配置专用的调度请求发送资源，用于EP发送调度请求信息。Optionally, in a case where the number of access end nodes EP is small in the cluster area, the CH may pre-configure a dedicated scheduling request for the EP to send a resource, and the EP sends the scheduling request information.

对于簇区域内接入末端节点数量较多的情况下，CH可以为多个EP配置公共的调度请求消息发送资源池，EP通过抢占方式发送调度请求消息。For a large number of access end nodes in the cluster area, the CH may configure a common scheduling request message for multiple EPs to send a resource pool, and the EP sends a scheduling request message in a preemptive manner.

对于专用调度请求配置情况下，由于CH可以根据接收到的调度请求的资源位置判断发送调度请求的EP标识信息，因此调度请求中无需携带EP标识信息。对于基于发送资源池的调度请求配置方式，EP发送的调度请求可以携带EP ID，从而帮助CH确定EP标识。In the case of the configuration of the dedicated scheduling request, the CH can determine the EP identification information of the scheduling request according to the resource location of the received scheduling request, so the EP identification information does not need to be carried in the scheduling request. For the configuration of the scheduling request based on the sending resource pool, the scheduling request sent by the EP may carry the EP ID, thereby helping the CH to determine the EP identifier.

可选的，如果***允许EP同时激活针对不同目标端的并行会话，则CH可以为不同的会话配置唯一的会话标识(或称为通信组标识)，这样EP发送的调度请求可以携带会话标识，而不用携带EP ID(标识)。当然，也可以会话标识和EP ID都携带。Optionally, if the system allows the EP to simultaneously activate parallel sessions for different target terminals, the CH may configure a unique session identifier (or a communication group identifier) for different sessions, so that the scheduling request sent by the EP may carry the session identifier, and Do not carry an EP ID. Of course, both the session identifier and the EP ID can be carried.

步骤2：CH根据当前***无线资源占用情况为EP进行无线资源配置。Step 2: The CH performs radio resource configuration for the EP according to the current system radio resource occupancy.

如果***中当前子帧有足够资源为EP进行无线资源配置，则CH为EP配置当前子帧的无线资源，如果当前子帧没有足够的传输资源，则CH可为EP配置后续子帧的无线传输资源。CH在为EP进行无线资源配置时，可以考虑EP业务的紧急程度，优先对紧急程度高的业务进行无线资源配置。If the current subframe in the system has sufficient resources to configure the radio resource for the EP, the CH configures the radio resource of the current subframe for the EP. If the current subframe does not have sufficient transmission resources, the CH may configure the radio transmission of the subsequent subframe for the EP. Resources. When configuring the radio resource for the EP, the CH can consider the urgency of the EP service and prioritize the radio resource allocation for the urgency service.

CH确定在确定调度信息后，可以通过单播或广播方式发送针对特定传输的无线资源配置信息。The CH determines that after determining the scheduling information, the radio resource configuration information for the specific transmission may be sent by unicast or broadcast.

其中，针对特定传输的无线资源配置信息可以通过发送端EP的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。The radio resource configuration information for the specific transmission may be indicated by the identifier of the sending end EP, or may be indicated by the session ID (Session ID) configured between the specific communication pairs.

可选的，CH可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。Optionally, the CH may simultaneously indicate radio resource configuration information for multiple wireless transmissions in one message.

发送端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的自身的EP标识或 Session ID进行比较，从而确定无线资源配置信息中是否有针对自己的无线资源配置。The sender EP sends the EP identification information carried in the transmission configuration and the scheduling indication according to the CH, or the Session ID (or the communication group identifier ID) of the specific session activated by the EP and the pre-saved EP identifier or The session ID is compared to determine whether there is a radio resource configuration for the radio resource configuration information.

在实施中，传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC(Mobile Service Switch Center，移动业务交换中心)等级，MIMO(多输入多输出)配置等)。In the implementation, the transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also choose to carry the transmission parameter configuration (for example, MSC (Mobile Service Switch Center) level, MIMO (multiple input multiple output) configuration Wait).

接收端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端EP标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。The sending end EP carries the sending end EP identification information carried in the transmission configuration and the scheduling indication according to the CH, or the session ID (or the communication group identification ID) of the specific session activated by the EP, and the pre-saved sender EP identifier or session. The IDs are compared to determine whether there is a transmission for the radio resource configuration information that needs to be received by itself, and a radio resource configuration used for the transmission.

如果发送端EP在当前CH发送的传输配置与调度指示中没有收到针对自身传输的无线资源配置，则EP可以根据预先配置的定时器时长，启动定时器(例如定时器时长为3个子帧长度)，并在定时器超时后仍没有收到无线资源配置的情况下重新发起无线资源请求。If the transmitting EP does not receive the radio resource configuration for the transmission in the transmission configuration and the scheduling indication of the current CH, the EP may start the timer according to the pre-configured timer duration (for example, the timer duration is 3 subframe lengths). ), and re-initiate the radio resource request if the radio resource configuration is not received after the timer expires.

步骤3：发送端EP将数据包首先封装成用于物理层传输的传输块，并根据CH指示的资源进行数据传输块的发送。Step 3: The transmitting end EP first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the resource indicated by the CH.

其中，调制编码方式可以是固定或可变的，如果是固定的，发送端EP可以不将调制编码方式通知接收端EP；如果是可变的，发送端EP可以将调制编码方式通知接收端EP。The modulation and coding mode may be fixed or variable. If it is fixed, the transmitting end EP may not notify the receiving end EP of the modulation and coding mode; if it is variable, the transmitting end EP may notify the receiving end EP of the modulation and coding mode. .

比如发送端EP可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the transmitting end EP can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤4：接收端EP根据步骤2接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 4: The receiving end EP determines the receiving resource set according to the transmission configuration and resource indication information received in step 2, and in combination with the session set sessions activated by itself.

接收端EP根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。The receiving end EP determines the modulation and coding mode used by the data portion according to the control portion of the data transmission block, thereby demodulating the data portion.

由于接收端EP可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端EP(这里的发送端EP可能还包括CH)，因此接收端EP可能需要同时对多个发送端EP使用的传输资源进行并行接收。Since the receiving end EP may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender EPs (here, the sender EP may also include CH), so the receiving end EP may need to send multiple packets at the same time. The transmission resources used by the end EP are received in parallel.

根据实际接收情况(成功或失败)，接收端EP使用与接收资源对应的反馈信道资源，向发送端EP发送ACK(Acknowledged Message，响应消息)或NACK(Negative ACKnowledge，错误应答指令)反馈信息。如果在当前时刻接收端EP并行对来自不同发送端EP的多路传输进行了并行接收，那么接收端EP也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end EP uses the feedback channel resource corresponding to the receiving resource to send an ACK (Acknowledged Message) or NACK (Negative ACKnowledge) feedback information to the transmitting end EP. If the receiving end EP concurrently receives the multiplex transmissions from different transmitting terminals EP in parallel at the current moment, the receiving end EP also performs corresponding feedback on the multiplex transmission.

场景二、EP到CH的单跳传输Scenario 2: Single-hop transmission from EP to CH

在EP到CH的传输情况下，由于CH同时作为资源调度实体和接收实体(CH可以是在簇区域内具体调度功能的特定EP)，因此CH作为接收端的部分无需通过空口接收“传输配置和调度资源指示”信息，而可以通过内部实体之间的交互获得相关信息。 In the case of the EP-to-CH transmission, since the CH serves as both the resource scheduling entity and the receiving entity (the CH can be a specific EP that specifically schedules functions in the cluster area), the CH as the receiving end does not need to receive the transmission configuration and scheduling through the air interface. The resource indicates "information", and related information can be obtained through interaction between internal entities.

如图10所示，本发明实施例动态自组织网络中EP到CH的单跳传输包括：As shown in FIG. 10, the single-hop transmission of the EP to the CH in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：数据包在到达发送端EP后，发送端EP向CH请求无线资源配置。Step 1: After the data packet arrives at the transmitting end EP, the transmitting end EP requests the radio resource configuration from the CH.

可选的，如果***允许EP同时激活针对不同目标端的并行会话，则CH可以为不同的会话配置唯一的会话标识(或称为通信组标识)，这样EP发送的调度请求可以携带会话标识，而不用携带EP ID。当然，也可以会话标识和EP ID都携带。Optionally, if the system allows the EP to simultaneously activate parallel sessions for different target terminals, the CH may configure a unique session identifier (or a communication group identifier) for different sessions, so that the scheduling request sent by the EP may carry the session identifier, and No need to carry an EP ID. Of course, both the session identifier and the EP ID can be carried.

发送端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的自身的EP标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自己的无线资源配置。The sender EP is configured according to the transmission configuration of the CH and the sender EP identification information carried in the scheduling indication, or the session ID (or the communication group identifier ID) of the specific session activated by the EP, and the pre-saved EP identifier or session. The IDs are compared to determine whether there is a radio resource configuration for the radio resource configuration information.

在实施中，传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC等级，MIMO配置等)。In an implementation, the transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also choose to carry the transmission parameter configuration (eg, MSC level, MIMO configuration, etc.).

步骤3：发送端EP将数据包首先封装成用于物理层传输的传输块，并根据CH指示的资源进行数据传输块的发送。 Step 3: The transmitting end EP first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the resource indicated by the CH.

步骤4：CH根据步骤2产生的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 4: The CH determines the received resource set according to the transmission configuration and resource indication information generated in step 2, and in combination with the session set sessions activated by itself.

CH根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。The CH determines the modulation and coding mode used by the data portion according to the control portion of the data transmission block, thereby demodulating the data portion.

由于CH可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端EP，因此CH可能需要同时对多个发送端EP使用的传输资源进行并行接收。Since the CH may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender EPs, so the CH may need to simultaneously receive the transmission resources used by multiple sender EPs in parallel.

根据实际接收情况(成功或失败)，CH使用与接收资源对应的反馈信道资源，向发送端EP发送ACK或NACK反馈信息。如果在当前时刻CH并行来自不同发送端EP的多路传输进行了并行接收，那么CH也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the CH uses the feedback channel resource corresponding to the received resource to send ACK or NACK feedback information to the transmitting end EP. If the multiplex transmission from the different transmitting end EPs is parallelly received at the current time CH, the CH also performs corresponding feedback on the multiplex transmission.

场景三、CH到EP的单跳传输Scene 3, single-hop transmission from CH to EP

在CH到EP的传输情况下，由于CH同时作为资源调度实体和发送实体(CH可以是在簇区域内具体调度功能的特定EP)，因此CH作为发送端的部分无需通过空口接收“传输配置和调度资源指示”信息，而可以通过内部实体之间的交互获得相关信息。In the case of the transmission of the CH to the EP, since the CH serves as both the resource scheduling entity and the sending entity (the CH can be a specific EP that specifically schedules functions in the cluster area), the part of the CH that serves as the transmitting end does not need to receive the transmission configuration and scheduling through the air interface. The resource indicates "information", and related information can be obtained through interaction between internal entities.

如图11所示，本发明实施例动态自组织网络中CH到EP的单跳传输包括：As shown in FIG. 11, the single-hop transmission of CH to EP in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：数据包到达CH后，CH根据当前***无线资源占用情况为自身数据传输进行无线资源分配。Step 1: After the data packet arrives at the CH, the CH allocates radio resources for its own data transmission according to the current system radio resource occupancy.

如果***中当前子帧有足够资源为CH传输进行无线资源分配，则CH为自身传输分配当前子帧的无线资源，如果当前子帧没有足够的传输资源，则CH可为自身传输分配后续子帧的无线传输资源。CH在为自身进行无线资源分配时，可以考虑当前业务的紧急程度，优先对紧急程度高的业务进行无线资源分配。If the current subframe in the system has sufficient resources for radio resource allocation for CH transmission, the CH allocates the radio resource of the current subframe for its own transmission, and if the current subframe does not have sufficient transmission resources, the CH may allocate a subsequent subframe for its own transmission. Wireless transmission resources. When the CH allocates radio resources for itself, it can consider the urgency of the current service and prioritize radio resource allocation for services with high urgency.

CH确定调度信息后，通过单播或广播方式发送针对特定传输的无线资源配置信息，其中针对特定传输的无线资源配置信息可以通过发送端CH的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。CH可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。After the CH determines the scheduling information, the radio resource configuration information for the specific transmission is sent by using a unicast or a broadcast manner, where the radio resource configuration information for the specific transmission may be indicated by the identifier of the sending end CH, or may be The configured session ID is indicated. The CH may simultaneously indicate radio resource configuration information for multiple wireless transmissions in one message.

接收端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的自身的EP标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自己的无线资源配置。The receiving end EP is configured according to the transmitting end configured by the CH and the sending end EP identification information carried in the scheduling indication, or the session ID (or the communication group identification ID) of the specific session activated by the EP and the pre-saved EP identifier or session. The IDs are compared to determine whether there is a radio resource configuration for the radio resource configuration information.

在实施中，传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC等级，MIMO配置等)。 In an implementation, the transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also choose to carry the transmission parameter configuration (eg, MSC level, MIMO configuration, etc.).

步骤2：CH将数据包首先封装成用于物理层传输的数据传输块，并会用步骤1确定的资源进行数据传输块的发送。Step 2: The CH first encapsulates the data packet into a data transport block for physical layer transmission, and transmits the data transport block with the resource determined in step 1.

其中，调制编码方式可以是固定或可变的，如果是固定的，CH可以不将调制编码方式通知接收端EP；如果是可变的，CH可以将调制编码方式通知接收端EP。The modulation coding mode may be fixed or variable. If it is fixed, the CH may not notify the receiving end EP of the modulation and coding mode; if it is variable, the CH may notify the receiving end EP of the modulation and coding mode.

比如CH可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the CH may indicate the modulation and coding mode used by the data portion of the transport block through the control portion of the transport block, thereby achieving the purpose of dynamically changing the data partial modulation and coding scheme.

步骤3：接收端EP根据步骤1接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 3: The receiving end EP determines the receiving resource set according to the transmission configuration and resource indication information received in step 1 and in combination with the session set sessions activated by itself.

由于接收端EP可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端EP(这里CH被看成是特殊功能的EP)，因此接收端EP可能需要同时对多个发送端EP使用的传输资源进行并行接收。Since the receiving end EP may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender EPs (here CH is regarded as a special function EP), so the receiving end EP may need to simultaneously multiple The transmission resources used by the transmitting end EP are received in parallel.

根据实际接收情况(成功或失败)，接收端EP使用与接收资源对应的反馈信道资源，向CH发送ACK或NACK反馈信息。如果在当前时刻接收端EP并行来自不同发送端EP或CH的多路传输进行了并行接收，那么接收端EP也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end EP uses the feedback channel resource corresponding to the receiving resource to send ACK or NACK feedback information to the CH. If the receiving end EP concurrently receives parallel transmissions from different transmitting terminals EP or CH at the current moment, the receiving end EP also performs corresponding feedback on the multiplex transmission.

场景四、EP到EP的单跳周期性业务传输Scenario 4: Single-hop periodic service transmission from EP to EP

对于周期性业务传输，首先要激活周期性业务会话，发送端EP在首个周期性业务会话数据包到达时刻向CH请求传输资源，CH根据周期性业务会话的周期，为该会话配置以业务周期为间隔的持续资源分配。在周期性业务会话后续数据包到达时，发送端EP无需重新请求调度资源，而是直接使用持续调度资源进行传输。在该周期性业务会话结束后，通过周期性业务会话去激活过程触发CH对持续资源分配进行释放。For the periodic service transmission, the periodic service session is first activated, and the transmitting end EP requests the transmission resource to the CH at the arrival time of the first periodic service session data packet, and the CH configures the service period for the session according to the periodicity of the periodic service session. A persistent resource allocation for the interval. When a subsequent data packet arrives in a periodic service session, the transmitting end EP does not need to re-request the scheduling resource, but directly uses the persistent scheduling resource for transmission. After the periodic service session ends, the periodic service session deactivation process triggers the CH to release the persistent resource allocation.

如图12所示，本发明实施例动态自组织网络中EP到EP的单跳周期性业务传输方法包括：As shown in FIG. 12, the single-hop periodic service transmission method of the EP to the EP in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：通过周期性业务会话激活过程，发送端EP、CH和接收端EP分别保存关于周期性业务会话的标识、周期、数据包大小等信息。Step 1: Through the periodic service session activation process, the sender EP, the CH, and the receiver EP respectively store information about the identity, period, and packet size of the periodic service session.

步骤2：发送端EP的首个数据包到达后，发送端EP向CH发送调度请求，在调度请求中携带周期性业务指示信息(例如周期性业务会话标识)。Step 2: After the first data packet of the transmitting end EP arrives, the sending end EP sends a scheduling request to the CH, and the scheduling request carries periodic service indication information (for example, a periodic service session identifier).

CH根据预先保存的周期性业务会话的周期，数据包大小，为发送端EP配置持续调度资源，持续资源分配的周期与业务周期性业务会话周期一致。The CH configures a persistent scheduling resource for the transmitting end EP according to the period of the pre-scheduled periodic service session and the data packet size, and the period of the persistent resource allocation is consistent with the service periodic service session period.

步骤3：CH确定调度信息后，通过单播或广播方式发送针对特定传输的持续无线资源配置信息，持续无线资源配置包括资源的起始位置，以及资源分配的周期。Step 3: After determining the scheduling information, the CH sends persistent radio resource configuration information for a specific transmission by using a unicast or a broadcast manner, where the persistent radio resource configuration includes a starting position of the resource and a period of resource allocation.

其中，针对特定传输的无线资源配置信息可以通过发送端EP的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。CH可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。The radio resource configuration information for a specific transmission may be indicated by the identifier of the sending end EP, or Instructed by a session ID (Session ID) configured between specific communication pairs. The CH may simultaneously indicate radio resource configuration information for multiple wireless transmissions in one message.

发送端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端EP标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。如果有针对自身的持续资源分配，则保存持续资源分配配置，用于后续周期性到达数据包传输。传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC等级，MIMO配置等)。The sending end EP carries the sending end EP identification information carried in the transmission configuration and the scheduling indication sent by the CH, or the session ID (or the communication group identification ID) of the specific session activated by the EP and the pre-saved sender EP identifier or session. The IDs are compared to determine whether there is a transmission for the radio resource configuration information that needs to be received by itself, and a radio resource configuration used for the transmission. If there is a persistent resource allocation for itself, the persistent resource allocation configuration is saved for subsequent periodic arrival of the packet transmission. The transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also optionally carry the transmission parameter configuration (eg, MSC level, MIMO configuration, etc.).

接收端EP根据CH发送的传输配置与调度指示中携带的发送端EP标识信息，或针对EP激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端EP标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。如果有针对自身的持续资源分配，则保存持续资源分配配置，用于后续周期性到达数据包的接收。The sending end EP carries the sending end EP identification information carried in the transmission configuration and the scheduling indication according to the CH, or the session ID (or the communication group identification ID) of the specific session activated by the EP, and the pre-saved sender EP identifier or session. The IDs are compared to determine whether there is a transmission for the radio resource configuration information that needs to be received by itself, and a radio resource configuration used for the transmission. If there is a persistent resource allocation for itself, the persistent resource allocation configuration is saved for subsequent periodic arrival of the data packet.

步骤4：发送端EP将数据包首先封装成用于物理层传输的传输块，并根据持续资源配置进行数据传输块的发送。Step 4: The transmitting end EP first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the persistent resource configuration.

比如EP可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the EP can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤5：接收端EP根据步骤3保存的持续资源分配信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 5: The receiving end EP determines the receiving resource set according to the persistent resource allocation information saved in step 3 and in combination with the session set sessions activated by itself.

接收端EP根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。由于接收端CH可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端EP，因此接收端CH可能需要同时对多个发送端EP使用的传输资源进行并行接收。The receiving end EP determines the modulation and coding mode used by the data portion according to the control portion of the data transmission block, thereby demodulating the data portion. Since the receiving end CH may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender EPs, so the receiving CH may need to simultaneously receive the transmission resources used by multiple sender EPs in parallel.

根据实际接收情况(成功或失败)，接收端EP使用与接收资源对应的反馈信道资源，向发送端EP，发送ACK或NACK反馈信息。如果在当前时刻接收端EP并行来自不同发送端EP的多路传输进行了并行接收，那么接收端EP也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end EP uses the feedback channel resource corresponding to the receiving resource to send ACK or NACK feedback information to the transmitting end EP. If the receiving end EP in parallel and the multiplex transmission from different transmitting end EPs are simultaneously received in parallel, the receiving end EP also performs corresponding feedback on the multiplex transmission.

步骤6：周期性业务会话的后续数据包到达时，发送端EP无需发送调度请求，而是使用“预分配”的持续资源分配获得的配置，直接进行数据发送。对于周期性业务会话的接收端EP，在使用持续资源分配获得的配置的生效时刻，对周期性业务后续到达的数据包传输，使用持续资源分配获得的配置进行接收。Step 6: When the subsequent data packet of the periodic service session arrives, the transmitting end EP does not need to send the scheduling request, but uses the configuration obtained by the “pre-allocated” persistent resource allocation to directly perform data transmission. For the receiving end EP of the periodic service session, the data packet transmission that is subsequently arrived by the periodic service is received at the effective time of the configuration obtained by the persistent resource allocation, and the configuration obtained by the persistent resource allocation is received.

步骤7：在周期性业务会话结束后，通过周期性业务会话去激活过程，发送端EP、CH 和接收端EP分别释放关于周期性业务会话的上行文信息。Step 7: After the periodic service session ends, the process is deactivated through the periodic service session, and the sending end EP, CH The uplink information about the periodic service session is released separately from the receiving end EP.

此外，发送端EP、CH和接收端EP将各自释放针对周期性业务传输的持续资源分配。In addition, the transmitting end EP, CH and the receiving end EP will each release a persistent resource allocation for periodic traffic transmissions.

场景五、EP到EP的多跳传输方案1Scenario 5: EP to EP multi-hop transmission scheme 1

在该方法EP到EP的多跳传输过程中，发送端EP到中继EP，以及中继EP到接收端EP的传输采用相互独立的传输过程，每跳采用的传输过程，与单跳传输过程一致。本多跳传输方案同时支持动态路由方案，同时支持静态路由方案。对于动态路由方案发送端EP可以动态选择中继EP(CH被看成是特殊EP)进行数据转发。In the multi-hop transmission process of the method EP to EP, the transmission end EP to the relay EP, and the transmission of the relay EP to the receiving end EP adopt independent transmission processes, the transmission process adopted by each hop, and the single-hop transmission process. Consistent. The multi-hop transmission scheme supports both dynamic routing schemes and static routing schemes. For the dynamic routing scheme, the transmitting end EP can dynamically select the relay EP (CH is regarded as a special EP) for data forwarding.

如图13所示，本发明实施例动态自组织网络中第一种EP到EP的多跳传输方法包括：As shown in FIG. 13, the first EP to EP multi-hop transmission method in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：发送端EP到中继EP的传输过程与场景一单跳传输过程一致，为提高传输可靠性，可采用动态路由方案，发送端EP到接收端EP的数据传输可以动态选择中继EP或CH进行数据包的转发。Step 1: The transmission process of the EP to the relay EP is the same as that of the scenario. The dynamic routing scheme can be adopted to improve the transmission reliability. The data transmission from the EP to the receiver EP can dynamically select the relay EP. Or CH forwards the packet.

对于固定路由，即中继EP固定的情况下，对于周期性业务传输也可以使用场景四单跳周期性业务传输方案。For a fixed route, that is, when the relay EP is fixed, the scenario four single-hop periodic service transmission scheme can also be used for the periodic service transmission.

步骤2：中继EP或CH从发送端EP收到转发数据后对按照场景一的单跳传输方式对数据包进行转发，最终将数据包发送到接收端EP节点。Step 2: After receiving the forwarding data from the transmitting EP, the relay EP or CH forwards the data packet to the single-hop transmission mode according to scenario 1, and finally sends the data packet to the receiving end EP node.

场景六、EP到EP的多跳传输方案2Scenario 6, EP to EP multi-hop transmission scheme 2

本方案仅适用于静态路由方案，即在发送端EP到接收端EP的会话建立过程中，确定固定路由，CH为发送端EP到中继EP的传输，以及中继EP到接收端EP的传输分配资源。This solution is only applicable to the static routing scheme, that is, during the session establishment process from the sender EP to the receiver EP, the fixed route is determined, the CH is the transmission from the sender EP to the relay EP, and the transmission from the relay EP to the receiver EP. resource allocation.

如图14所示，本发明实施例动态自组织网络中第二种EP到EP的多跳传输方法包括：As shown in FIG. 14, the second EP to EP multi-hop transmission method in the dynamic self-organizing network in the embodiment of the present invention includes:

步骤1：在会话建立过程中，发送端EP、CH、中继EP和接收端EP建立与该会话相关的静态路由关系。Step 1: During the session establishment process, the transmitting end EP, CH, relay EP, and receiving EP establish a static routing relationship related to the session.

步骤2：数据包到达后，发送端EP向CH发起调度请求，并携带会话标识。CH根据会话标识判断出是多跳传输，CH为发送端EP到接收端EP多跳传输进行资源分配。Step 2: After the data packet arrives, the sending end EP initiates a scheduling request to the CH and carries the session identifier. The CH determines that the multi-hop transmission is based on the session identifier, and the CH allocates resources from the transmitting end EP to the receiving end EP multi-hop transmission.

步骤3：CH通过单播或广播方式将多跳资源分配信息分别通知发送端EP、中继EP以及接收端EP。Step 3: The CH notifies the multi-hop resource allocation information to the transmitting end EP, the relay EP, and the receiving end EP respectively by unicast or broadcast.

发送端EP保存第一跳发送的资源配置。The sender EP saves the resource configuration sent by the first hop.

中继EP保存第一跳接收资源和第二跳发送资源配置。The relay EP saves the first hop receiving resource and the second hop sending resource configuration.

接收端EP保存第二跳接收资源配置。The receiving end EP saves the second hop receiving resource configuration.

传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC等级，MIMO配置等)。The transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also optionally carry the transmission parameter configuration (eg, MSC level, MIMO configuration, etc.).

步骤4：发送端EP将数据包首先封装成用于物理层传输的传输块，并根据CH指示的第一跳传输资源进行数据传输块的发送。Step 4: The transmitting end EP first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the first hop transmission resource indicated by the CH.

其中，调制编码方式可以是固定或可变的，如果是固定的，发送端EP可以不将调制编码方式通知接收端EP；如果是可变的，发送端EP可以将调制编码方式通知中继EP。Wherein, the modulation and coding mode may be fixed or variable, and if it is fixed, the transmitting end EP may not modulate The encoding mode notifies the receiving end EP; if it is variable, the transmitting end EP can notify the relay EP of the modulation and coding mode.

步骤5：中继EP根据步骤3接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 5: The relay EP determines the received resource set according to the transmission configuration and resource indication information received in step 3, and in combination with the session set sessions activated by itself.

由于接收端EP可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端EP(这里CH被看成是特殊功能的EP)，因此中继EP可能需要同时对多个发送端EP使用的传输资源进行并行接收。Since the receiving end EP may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender EPs (here CH is regarded as a special function EP), so the relay EP may need to simultaneously multiple The transmission resources used by the transmitting end EP are received in parallel.

根据实际接收情况(成功或失败)，中继EP使用与接收资源对应的反馈信道资源，向发送端EP发送ACK或NACK反馈信息。如果在当前时刻中继EP并行来自不同发送端EP的多路传输进行了并行接收，那么中继EP也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the relay EP uses the feedback channel resource corresponding to the received resource to send ACK or NACK feedback information to the transmitting end EP. If the relay EP in parallel at the current time and the multiplex transmission from different transmitter EPs are received in parallel, the relay EP also performs corresponding feedback on the multiplex transmission.

步骤6：中继EP将转发数据包首先封装成用于物理层传输的传输块，并根据CH指示的第二跳资源进行数据传输块的发送。Step 6: The relay EP first encapsulates the forwarded data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the second hop resource indicated by the CH.

其中，调制编码方式可以是固定或可变的，如果是固定的，中继EP可以不将调制编码方式通知接收端EP；如果是可变的，中继EP可以将调制编码方式通知接收端EP。The modulation and coding mode may be fixed or variable. If it is fixed, the relay EP may not notify the receiving end EP of the modulation and coding mode; if it is variable, the relay EP may notify the receiving end of the modulation and coding mode. .

比如中继EP可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the relay EP can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤7：接收端EP根据步骤3接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。接收端EP根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。Step 7: The receiving end EP determines the receiving resource set according to the transmission configuration and resource indication information received in step 3, and in combination with the session set sessions activated by itself. The receiving end EP determines the modulation and coding mode used by the data portion according to the control portion of the data transmission block, thereby demodulating the data portion.

根据实际接收情况(成功或失败)，接收端EP使用与接收资源对应的反馈信道资源，向发送端EP发送ACK或NACK反馈信息。如果在当前时刻中继EP并行来自不同发送端EP的多路传输进行了并行接收，那么接收端EP也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end EP uses the feedback channel resource corresponding to the receiving resource to send ACK or NACK feedback information to the transmitting end EP. If the relay EP in parallel at the current time and the multiplex transmission from different transmitter EPs are received in parallel, the receiving end EP also performs corresponding feedback on the multiplex transmission.

场景七、EP触发的资源去激活方案Scenario 7, EP triggered resource deactivation scheme

对于实施例4中针对周期性业务资源与调度方案中，一种情况是在业务结束后资源被释放，另一种场景是，EP用户设备可以能由于并关闭或者从簇区域中移出的情况，在这种情况下，EP用户设备需要触发CH提前终止资源预分配，从而达到节省无线资源的目的。本实施例以发端EP发生“去激活事件”为例进行说明，收端EP检测到“去激活事件”的处理过程类似。In the case of the periodic service resource and scheduling scheme in the fourth embodiment, one case is that the resource is released after the service ends, and the other scenario is that the EP user equipment can be removed and removed from the cluster area. In this case, the EP user equipment needs to trigger the CH to terminate the resource pre-allocation in advance, thereby achieving the purpose of saving radio resources. In this embodiment, the “deactivation event” occurs at the originating EP as an example, and the receiving end EP detects the “deactivation event”. The process is similar.

如图15所示，本发明实施例动态自组织网络中去激活的方法包括：As shown in FIG. 15, the method for deactivating a dynamic self-organizing network according to an embodiment of the present invention includes:

步骤1：通过周期性业务会话激活过程，发送端EP、CH和接收端EP分别保存关于周期性业务会话的标识，周期、数据包大小等信息。Step 1: Through the periodic service session activation process, the sender EP, CH, and the receiving end EP respectively store information about the identity, period, and packet size of the periodic service session.

步骤2：发送端EP按照场景四中记载过程进行数据传输，接收端EP按照场景四记载过程进行接收。Step 2: The transmitting end EP performs data transmission according to the process described in the scenario 4, and the receiving end EP receives the data according to the process described in the scenario 4.

步骤3：发送端EP检测到“去激活事件”从而触发CH提前释放针对周期性业务传输预分配的资源。Step 3: The transmitting end EP detects a “deactivation event” to trigger the CH to release the pre-allocated resources for the periodic service transmission.

其中“去激活事件”包括但不限于EP用户设备关闭。The "deactivation event" includes but is not limited to the EP user equipment being turned off.

步骤4：发送端EP向CH发送“周期业务去激活指示”触发CH提前释放为本次周期性业务传输预先分配的无线资源，以及与周期性业务相关的上下文信息，上下文信息包括参数配置和有会话相关的临时标识等。Step 4: The sending end EP sends a "periodic service deactivation indication" to the CH to trigger the CH to release the pre-allocated radio resources for the periodic service transmission and the context information related to the periodic service, where the context information includes parameter configuration and Session-related temporary identifiers, etc.

步骤5：CH从发送端EP收到指示后，触发周期性业务会话去激活过程，以使发送端EP、CH和接收端EP分别释放关于周期性业务会话的上行文信息。Step 5: After receiving the indication from the sending end EP, the CH triggers the periodic service session deactivation process, so that the transmitting end EP, CH, and the receiving end EP respectively release the uplink information about the periodic service session.

此外发送端EP，CH和接收端EP将各自释放针对周期性业务传输的持续资源分配。In addition, the transmitting end EP, CH and the receiving end EP will each release a persistent resource allocation for periodic traffic transmission.

二、应用于蜂窝网络，且将“控制器”和“传输功能”合并Second, applied to the cellular network, and the "controller" and "transport function" are combined

场景一、用户设备到用户设备的单跳传输过程Scenario 1: Single-hop transmission process from user equipment to user equipment

针对用户设备到用户设备传输的动态调度方案，主要满足突发性业务的传输要求。The dynamic scheduling scheme for user equipment to user equipment transmission mainly meets the transmission requirements of bursty services.

如图16所示，本发明实施例蜂窝网络中用户设备到用户设备的单跳传输包括：As shown in FIG. 16, the single-hop transmission of the user equipment to the user equipment in the cellular network according to the embodiment of the present invention includes:

步骤1：数据包在到达发送端用户设备后，发送端用户设备向基站请求无线资源配置。Step 1: After the data packet arrives at the transmitting end user equipment, the transmitting end user equipment requests the radio resource configuration from the base station.

可选的，在服务区域内接入末端节点用户设备数量较少的情况下，基站可以预先为用户设备配置专用的调度请求发送资源，用于用户设备发送调度请求信息。Optionally, in a case where the number of user equipments of the end node is small in the service area, the base station may configure a dedicated scheduling request sending resource for the user equipment in advance, and the user equipment sends the scheduling request information.

对于服务区域内接入末端节点数量较多的情况下，基站可以为多个用户设备配置公共的调度请求消息发送资源池，用户设备通过抢占方式发送调度请求消息。For a large number of access end nodes in the service area, the base station may configure a common scheduling request message to send a resource pool for multiple user equipments, and the user equipment sends a scheduling request message in a preemptive manner.

对于专用调度请求配置情况下，由于基站可以根据接收到的调度请求的资源位置判断发送调度请求的用户设备标识信息，因此调度请求中无需携带用户设备标识信息。对于基于发送资源池的调度请求配置方式，用户设备发送的调度请求可以携带用户设备ID，从而帮助基站确定用户设备标识。For the configuration of the dedicated scheduling request, the base station can determine the user equipment identification information of the scheduling request according to the resource location of the received scheduling request, so the user equipment identification information does not need to be carried in the scheduling request. For the configuration of the scheduling request based on the sending resource pool, the scheduling request sent by the user equipment may carry the user equipment ID, thereby helping the base station determine the user equipment identifier.

可选的，如果***允许用户设备同时激活针对不同目标端的并行会话，则基站可以为不同的会话配置唯一的会话标识(或称为通信组标识)，这样用户设备发送的调度请求可以携带会话标识，而不用携带用户设备ID。当然，也可以会话标识和用户设备ID都携带。Optionally, if the system allows the user equipment to simultaneously activate parallel sessions for different target terminals, the base station may configure a unique session identifier (or a communication group identifier) for different sessions, so that the scheduling request sent by the user equipment may carry the session identifier. Without carrying the user device ID. Of course, the session identifier and the user equipment ID can also be carried.

步骤2：基站根据当前***无线资源占用情况为用户设备进行无线资源配置。Step 2: The base station performs radio resource configuration for the user equipment according to the current system radio resource occupation.

如果***中当前子帧有足够资源为用户设备进行无线资源配置，则基站为用户设备配置当前子帧的无线资源，如果当前子帧没有足够的传输资源，则基站可为用户设备配置后续子帧的无线传输资源。基站在为用户设备进行无线资源配置时，可以考虑用户设备业务的紧急程度，优先对紧急程度高的业务进行无线资源配置。If the current subframe in the system has sufficient resources to configure the radio resource for the user equipment, the base station allocates the user equipment. The radio resource of the current subframe is set. If the current subframe does not have sufficient transmission resources, the base station may configure the radio transmission resource of the subsequent subframe for the user equipment. When the base station performs radio resource configuration for the user equipment, the urgency of the user equipment service may be considered, and the radio resource configuration of the urgency service is preferentially performed.

基站确定在确定调度信息后，可以通过单播或广播方式发送针对特定传输的无线资源配置信息。The base station determines that after determining the scheduling information, the radio resource configuration information for the specific transmission may be sent by unicast or broadcast.

其中，针对特定传输的无线资源配置信息可以通过发送端用户设备的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。The radio resource configuration information for the specific transmission may be indicated by the identifier of the sending end user equipment, or may be indicated by the session ID (Session ID) configured between the specific communication pairs.

可选的，基站可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。Optionally, the base station may simultaneously indicate radio resource configuration information for multiple radio transmissions in one message.

发送端用户设备根据基站发送的传输配置与调度指示中携带的发送端用户设备标识信息，或针对用户设备激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的自身的用户设备标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自己的无线资源配置。The sender user equipment according to the transmission configuration and the scheduling indication sent by the base station, or the session ID (or the communication group identifier ID) of the specific session activated by the user equipment and the pre-saved user The device ID or the session ID is compared to determine whether there is a radio resource configuration for the radio resource configuration information.

接收端用户设备根据基站发送的传输配置与调度指示中携带的发送端用户设备标识信息，或针对用户设备激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端用户设备标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。The receiving end user equipment according to the transmission configuration and the scheduling indication sent by the base station, or the session ID (or the communication group identification ID) of the specific session activated by the user equipment and the pre-saved sender user. The device identifier or the session ID is compared to determine whether the radio resource configuration information has a transmission for which it needs to receive, and a radio resource configuration used by the transmission.

如果发送端用户设备在当前基站发送的传输配置与调度指示中没有收到针对自身传输的无线资源配置，则用户设备可以根据预先配置的定时器时长，启动定时器(例如定时器时长为3个子帧长度)，并在定时器超时后仍没有收到无线资源配置的情况下重新发起无线资源请求。If the transmitting end user equipment does not receive the radio resource configuration for the self-transmission in the transmission configuration and the scheduling indication sent by the current base station, the user equipment may start the timer according to the preset timer duration (for example, the timer duration is 3 sub-times). Frame length), and re-initiate the radio resource request if the radio resource configuration is not received after the timer expires.

步骤3：发送端用户设备将数据包首先封装成用于物理层传输的传输块，并根据基站指示的资源进行数据传输块的发送。Step 3: The transmitting end user equipment first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the resource indicated by the base station.

其中，调制编码方式可以是固定或可变的，如果是固定的，发送端用户设备可以不将调制编码方式通知接收端用户设备；如果是可变的，发送端用户设备可以将调制编码方式通知接收端用户设备。The modulation and coding mode may be fixed or variable. If it is fixed, the user equipment at the transmitting end may not notify the user equipment of the receiving end of the modulation and coding mode; if it is variable, the user equipment of the transmitting end may notify the modulation and coding mode. Receiver user equipment.

比如发送端用户设备可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the transmitting end user equipment can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤4：接收端用户设备根据步骤2接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 4: The receiving end user equipment determines the receiving resource set according to the transmission configuration and resource indication information received in step 2, and in combination with the activated session set sessions.

接收端用户设备根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。 The receiving end user equipment determines the modulation and coding mode used by the data part according to the control part of the data transmission block, thereby demodulating the data part.

由于接收端用户设备可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端用户设备(这里的发送端用户设备可能还包括基站)，因此接收端用户设备可能需要同时对多个发送端用户设备使用的传输资源进行并行接收。Since the receiving end user equipment may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender user devices (where the sender device device may also include the base station), so the receiving end user device may need to simultaneously The transmission resources used by multiple sender user equipments are received in parallel.

根据实际接收情况(成功或失败)，接收端用户设备使用与接收资源对应的反馈信道资源，向发送端用户设备发送ACK或NACK反馈信息。如果在当前时刻接收端用户设备并行对来自不同发送端用户设备的多路传输进行了并行接收，那么接收端用户设备也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end user equipment sends the ACK or NACK feedback information to the sending end user equipment by using the feedback channel resource corresponding to the receiving resource. If the receiving end user equipment performs parallel reception of multiplex transmissions from different transmitting end user equipments at the current moment, the receiving end user equipment also performs corresponding feedback on the multiplex transmission.

场景二、用户设备到基站的单跳传输Scenario 2: Single-hop transmission from the user equipment to the base station

在用户设备到基站的传输情况下，由于基站同时作为资源调度实体和接收实体(基站可以是在服务区域内具体调度功能的特定用户设备)，因此基站作为接收端的部分无需通过空口接收“传输配置和调度资源指示”信息，而可以通过内部实体之间的交互获得相关信息。In the case of the transmission from the user equipment to the base station, since the base station serves as both the resource scheduling entity and the receiving entity (the base station may be a specific user equipment that specifically schedules functions in the service area), the base station as the receiving end does not need to receive the transmission configuration through the air interface. And scheduling resource indications, and related information can be obtained through interaction between internal entities.

如图17所示，本发明实施例蜂窝网络中用户设备到基站的单跳传输包括：As shown in FIG. 17, the single-hop transmission of the user equipment to the base station in the cellular network according to the embodiment of the present invention includes:

如果***中当前子帧有足够资源为用户设备进行无线资源配置，则基站为用户设备配置当前子帧的无线资源，如果当前子帧没有足够的传输资源，则基站可为用户设备配置后续子帧的无线传输资源。基站在为用户设备进行无线资源配置时，可以考虑用户设备业务的紧急程度，优先对紧急程度高的业务进行无线资源配置。If the current subframe in the system has sufficient resources to configure the radio resource for the user equipment, the base station configures the radio resource of the current subframe for the user equipment, and if the current subframe does not have sufficient transmission resources, the base station may configure the subsequent subframe for the user equipment. Wireless transmission resources. When the base station performs radio resource configuration for the user equipment, the urgency of the user equipment service may be considered, and the radio resource configuration of the urgency service is preferentially performed.

其中，针对特定传输的无线资源配置信息可以通过发送端用户设备的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。The radio resource configuration information for the specific transmission may be indicated by the identifier of the user equipment at the sending end. It is also possible to indicate the session ID (Session ID) configured between specific communication pairs.

步骤4：基站根据步骤2产生的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 4: The base station determines the received resource set according to the transmission configuration and resource indication information generated in step 2, and in combination with the session set sessions activated by itself.

基站根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。The base station determines the modulation and coding mode used by the data portion according to the control portion of the data transmission block, thereby demodulating the data portion.

由于基站可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端用户设备，因此基站可能需要同时对多个发送端用户设备使用的传输资源进行并行接收。Since the base station may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender user devices, so the base station may need to simultaneously receive the transmission resources used by multiple sender user devices in parallel.

根据实际接收情况(成功或失败)，基站使用与接收资源对应的反馈信道资源，向发送端用户设备发送ACK或NACK反馈信息。如果在当前时刻基站并行来自不同发送端用户设备的多路传输进行了并行接收，那么基站也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the base station sends the ACK or NACK feedback information to the transmitting end user equipment by using the feedback channel resource corresponding to the receiving resource. If the base station parallels the multiplex transmission from different transmitting end user equipments in parallel at the current time, the base station also needs to perform corresponding feedback on the multiplex transmission.

场景三、基站到用户设备的单跳传输Scenario 3: Single-hop transmission from the base station to the user equipment

在基站到用户设备的传输情况下，由于基站同时作为资源调度实体和发送实体(基站可以是在服务区域内具体调度功能的特定用户设备)，因此基站作为发送端的部分无需通过空口接收“传输配置和调度资源指示”信息，而可以通过内部实体之间的交互获得相关信息。In the case of the transmission from the base station to the user equipment, since the base station serves as both the resource scheduling entity and the transmitting entity (the base station may be a specific user equipment that specifically schedules functions in the service area), the base station as the transmitting end does not need to receive the "transmission configuration" through the air interface. And scheduling resource indication" information, but can be related through interaction between internal entities information.

如图18所示，本发明实施例蜂窝网络中基站到用户设备的单跳传输包括：As shown in FIG. 18, the single-hop transmission from the base station to the user equipment in the cellular network according to the embodiment of the present invention includes:

步骤1：数据包到达基站后，基站根据当前***无线资源占用情况为自身数据传输进行无线资源分配。Step 1: After the data packet arrives at the base station, the base station performs radio resource allocation for its own data transmission according to the current system radio resource occupation.

如果***中当前子帧有足够资源为基站传输进行无线资源分配，则基站为自身传输分配当前子帧的无线资源，如果当前子帧没有足够的传输资源，则基站可为自身传输分配后续子帧的无线传输资源。基站在为自身进行无线资源分配时，可以考虑当前业务的紧急程度，优先对紧急程度高的业务进行无线资源分配。If the current subframe in the system has sufficient resources for the base station transmission to perform radio resource allocation, the base station allocates the radio resource of the current subframe for its own transmission, and if the current subframe does not have sufficient transmission resources, the base station may allocate a subsequent subframe for its own transmission. Wireless transmission resources. When the base station performs radio resource allocation for itself, it can consider the urgency of the current service and prioritize radio resource allocation for services with high urgency.

基站确定调度信息后，通过单播或广播方式发送针对特定传输的无线资源配置信息，其中针对特定传输的无线资源配置信息可以通过发送端基站的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。基站可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。After determining the scheduling information, the base station sends the radio resource configuration information for the specific transmission by using a unicast or a broadcast mode, where the radio resource configuration information for the specific transmission may be indicated by the identifier of the transmitting base station, or may be used for the specific communication pair. The configured session ID is indicated. The base station can simultaneously indicate radio resource configuration information for multiple radio transmissions in one message.

接收端用户设备根据基站发送的传输配置与调度指示中携带的发送端用户设备标识信息，或针对用户设备激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的自身的用户设备标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自己的无线资源配置。The user equipment identification information carried by the receiving end user equipment according to the transmission configuration and the scheduling indication sent by the base station, or the session ID (or the communication group identification ID) of the specific session activated by the user equipment and the pre-saved user The device ID or the session ID is compared to determine whether there is a radio resource configuration for the radio resource configuration information.

步骤2：基站将数据包首先封装成用于物理层传输的数据传输块，并会用步骤1确定的资源进行数据传输块的发送。Step 2: The base station first encapsulates the data packet into a data transmission block for physical layer transmission, and performs the transmission of the data transmission block by using the resource determined in step 1.

其中，调制编码方式可以是固定或可变的，如果是固定的，基站可以不将调制编码方式通知接收端用户设备；如果是可变的，基站可以将调制编码方式通知接收端用户设备。The modulation and coding mode may be fixed or variable. If it is fixed, the base station may not notify the receiving end user equipment of the modulation and coding mode; if it is variable, the base station may notify the receiving end user equipment of the modulation and coding mode.

比如基站可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the base station can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤3：接收端用户设备根据步骤1接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 3: The receiving end user equipment determines the receiving resource set according to the transmission configuration and resource indication information received in step 1 and in combination with the session set sessions activated by itself.

接收端用户设备根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。The receiving end user equipment determines the modulation and coding mode used by the data part according to the control part of the data transmission block, thereby demodulating the data part.

由于接收端用户设备可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端用户设备(这里基站被看成是特殊功能的用户设备)，因此接收端用户设备可能需要同时对多个发送端用户设备使用的传输资源进行并行接收。Since the receiving end user equipment may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender user devices (where the base station is regarded as a special function user device), so the receiving end user device may need At the same time, the transmission resources used by multiple transmitting end user equipments are received in parallel.

根据实际接收情况(成功或失败)，接收端用户设备使用与接收资源对应的反馈信道资源，向基站发送ACK或NACK反馈信息。如果在当前时刻接收端用户设备并行来自不同发送端用户设备或基站的多路传输进行了并行接收，那么接收端用户设备也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end user equipment sends the ACK or NACK feedback information to the base station by using the feedback channel resource corresponding to the receiving resource. If the receiving end user device is in parallel at the current moment, The multiplex transmission with the user equipment of the transmitting end or the base station is received in parallel, and the user equipment at the receiving end also performs corresponding feedback on the multiplex transmission.

场景四、用户设备到用户设备的单跳周期性业务传输Scenario 4: Single-hop periodic service transmission from user equipment to user equipment

对于周期性业务传输，首先要激活周期性业务会话，发送端用户设备在首个周期性业务会话数据包到达时刻向基站请求传输资源，基站根据周期性业务会话的周期，为该会话配置以业务周期为间隔的持续资源分配。在周期性业务会话后续数据包到达时，发送端用户设备无需重新请求调度资源，而是直接使用持续调度资源进行传输。在该周期性业务会话结束后，通过周期性业务会话去激活过程触发基站对持续资源分配进行释放。For the periodic service transmission, the periodic service session is first activated, and the transmitting end user equipment requests the transmission resource from the base station at the arrival time of the first periodic service session data packet, and the base station configures the service for the session according to the periodicity of the periodic service session. The period is the continuous resource allocation of the interval. When a subsequent data packet arrives in a periodic service session, the transmitting end user equipment does not need to re-request the scheduling resource, but directly uses the persistent scheduling resource for transmission. After the periodic service session ends, the periodic service session deactivation process triggers the base station to release the persistent resource allocation.

如图19所示，本发明实施例蜂窝网络中用户设备到用户设备的单跳周期性业务传输方法包括：As shown in FIG. 19, a single-hop periodic service transmission method of a user equipment to a user equipment in a cellular network according to an embodiment of the present invention includes:

步骤1：通过周期性业务会话激活过程，发送端用户设备、基站和接收端用户设备分别保存关于周期性业务会话的标识、周期、数据包大小等信息。Step 1: Through the periodic service session activation process, the sending user equipment, the base station, and the receiving end user equipment respectively save information about the identity, period, and packet size of the periodic service session.

步骤2：发送端用户设备的首个数据包到达后，发送端用户设备向基站发送调度请求，在调度请求中携带周期性业务指示信息(例如周期性业务会话标识)。Step 2: After the first data packet of the user equipment of the transmitting end arrives, the transmitting user equipment sends a scheduling request to the base station, where the scheduling request carries periodic service indication information (for example, a periodic service session identifier).

基站根据预先保存的周期性业务会话的周期，数据包大小，为发送端用户设备配置持续调度资源，持续资源分配的周期与业务周期性业务会话周期一致。The base station configures a persistent scheduling resource for the user equipment of the sending end according to the period of the pre-scheduled periodic service session and the data packet size, and the period of the persistent resource allocation is consistent with the service periodic service session period.

步骤3：基站确定调度信息后，通过单播或广播方式发送针对特定传输的持续无线资源配置信息，持续无线资源配置包括资源的起始位置，以及资源分配的周期。Step 3: After determining the scheduling information, the base station sends persistent radio resource configuration information for a specific transmission by using a unicast or broadcast manner, where the persistent radio resource configuration includes a starting position of the resource and a period of resource allocation.

其中，针对特定传输的无线资源配置信息可以通过发送端用户设备的标识进行指示，也可以通过为特定通信对之间配置的会话ID(Session ID)进行指示。基站可以在一条消息中同时指示针对多个无线传输的无线资源配置信息。The radio resource configuration information for the specific transmission may be indicated by the identifier of the sending end user equipment, or may be indicated by the session ID (Session ID) configured between the specific communication pairs. The base station can simultaneously indicate radio resource configuration information for multiple radio transmissions in one message.

发送端用户设备根据基站发送的传输配置与调度指示中携带的发送端用户设备标识信息，或针对用户设备激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端用户设备标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。如果有针对自身的持续资源分配，则保存持续资源分配配置，用于后续周期性到达数据包传输。传输配置与调度指示中携带针对传输采用的无线资源指示，也可以选择携带传输参数配置(例如MSC等级，MIMO配置等)。The sending end user equipment according to the transmission configuration and the scheduling indication sent by the base station, or the session ID (or the communication group identification ID) of the specific session activated by the user equipment and the pre-saved sender user The device identifier or the session ID is compared to determine whether the radio resource configuration information has a transmission for which it needs to receive, and a radio resource configuration used by the transmission. If there is a persistent resource allocation for itself, the persistent resource allocation configuration is saved for subsequent periodic arrival of the packet transmission. The transmission configuration and the scheduling indication carry the radio resource indication used for the transmission, and may also optionally carry the transmission parameter configuration (eg, MSC level, MIMO configuration, etc.).

接收端用户设备根据基站发送的传输配置与调度指示中携带的发送端用户设备标识信息，或针对用户设备激活的特定会话的Session ID(或称为通信组标识ID)与预先保存的发送端用户设备标识或Session ID进行比较，从而确定无线资源配置信息中是否有针对自身需要进行接收的传输，以及该传输使用的无线资源配置。如果有针对自身的持续资源分配，则保存持续资源分配配置，用于后续周期性到达数据包的接收。 The receiving end user equipment according to the transmission configuration and the scheduling indication sent by the base station, or the session ID (or the communication group identification ID) of the specific session activated by the user equipment and the pre-saved sender user. The device identifier or the session ID is compared to determine whether the radio resource configuration information has a transmission for which it needs to receive, and a radio resource configuration used by the transmission. If there is a persistent resource allocation for itself, the persistent resource allocation configuration is saved for subsequent periodic arrival of the data packet.

步骤4：发送端用户设备将数据包首先封装成用于物理层传输的传输块，并根据持续资源配置进行数据传输块的发送。Step 4: The transmitting end user equipment first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the persistent resource configuration.

比如用户设备可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the user equipment can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤5：接收端用户设备根据步骤3保存的持续资源分配信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 5: The receiving end user equipment determines the receiving resource set according to the persistent resource allocation information saved in step 3 and in combination with the session set sessions activated by itself.

接收端用户设备根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。由于接收端基站可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端用户设备，因此接收端基站可能需要同时对多个发送端用户设备使用的传输资源进行并行接收。The receiving end user equipment determines the modulation and coding mode used by the data part according to the control part of the data transmission block, thereby demodulating the data part. Since the receiving base station may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender user devices, so the receiving base station may need to simultaneously receive the transmission resources used by multiple sender user devices in parallel. .

根据实际接收情况(成功或失败)，接收端用户设备使用与接收资源对应的反馈信道资源，向发送端用户设备，发送ACK或NACK反馈信息。如果在当前时刻接收端用户设备并行来自不同发送端用户设备的多路传输进行了并行接收，那么接收端用户设备也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end user equipment sends the ACK or NACK feedback information to the sending end user equipment by using the feedback channel resource corresponding to the receiving resource. If, at the current moment, the receiving end user equipment performs parallel reception in parallel with the multiplex transmission from different transmitting end user equipments, the receiving end user equipment also needs to perform corresponding feedback on the multiplex transmission.

步骤6：周期性业务会话的后续数据包到达时，发送端用户设备无需发送调度请求，而是使用“预分配”的持续资源分配获得的配置，直接进行数据发送。对于周期性业务会话的接收端用户设备，在使用持续资源分配获得的配置的生效时刻，对周期性业务后续到达的数据包传输，使用持续资源分配获得的配置进行接收。Step 6: When the subsequent data packet of the periodic service session arrives, the transmitting end user equipment does not need to send a scheduling request, but uses the configuration obtained by the “pre-allocated” persistent resource allocation to directly perform data transmission. For the receiving end user equipment of the periodic service session, the data packet transmission that is subsequently arrived by the periodic service is received at the effective time of the configuration obtained by using the persistent resource allocation, and the configuration obtained by the persistent resource allocation is received.

步骤7：在周期性业务会话结束后，通过周期性业务会话去激活过程，发送端用户设备、基站和接收端用户设备分别释放关于周期性业务会话的上行文信息。Step 7: After the periodic service session is terminated, the user equipment, the base station, and the receiving end user equipment respectively release the uplink information about the periodic service session.

此外，发送端用户设备、基站和接收端用户设备将各自释放针对周期性业务传输的持续资源分配。In addition, the transmitting end user equipment, the base station and the receiving end user equipment will each release a persistent resource allocation for periodic traffic transmissions.

场景五、用户设备到用户设备的多跳传输方案1Scenario 5: Multi-hop transmission scheme of user equipment to user equipment 1

在该方法用户设备到用户设备的多跳传输过程中，发送端用户设备到中继用户设备，以及中继用户设备到接收端用户设备的传输采用相互独立的传输过程，每跳采用的传输过程，与单跳传输过程一致。本多跳传输方案同时支持动态路由方案，同时支持静态路由方案。对于动态路由方案发送端用户设备可以动态选择中继用户设备(基站被看成是特殊用户设备)进行数据转发。In the multi-hop transmission process of the user equipment to the user equipment, the transmission of the user equipment to the relay user equipment, and the transmission of the relay user equipment to the user equipment of the receiving end are mutually independent transmission processes, and the transmission process adopted by each hop is adopted. , consistent with the single-hop transmission process. The multi-hop transmission scheme supports both dynamic routing schemes and static routing schemes. For the dynamic routing scheme, the user equipment at the transmitting end can dynamically select the relay user equipment (the base station is regarded as a special user equipment) for data forwarding.

如图20所示，本发明实施例蜂窝网络中第一种用户设备到用户设备的多跳传输方法包括： As shown in FIG. 20, the multi-hop transmission method of the first user equipment to the user equipment in the cellular network according to the embodiment of the present invention includes:

步骤1：发送端用户设备到中继用户设备的传输过程与场景一单跳传输过程一致，为提高传输可靠性，可采用动态路由方案，发送端用户设备到接收端用户设备的数据传输可以动态选择中继用户设备或基站进行数据包的转发。Step 1: The transmission process from the user equipment to the relay user equipment is the same as that in the scenario. The dynamic routing scheme can be adopted to improve the transmission reliability. The data transmission from the user equipment to the user equipment at the receiving end can be dynamic. Select a relay user equipment or base station to forward data packets.

对于固定路由，即中继用户设备固定的情况下，对于周期性业务传输也可以使用场景四单跳周期性业务传输方案。For a fixed route, that is, when the relay user equipment is fixed, the scenario four single-hop periodic service transmission scheme may also be used for the periodic service transmission.

步骤2：中继用户设备或基站从发送端用户设备收到转发数据后对按照场景一的单跳传输方式对数据包进行转发，最终将数据包发送到接收端用户设备节点。Step 2: After receiving the forwarding data from the transmitting user equipment, the relay user equipment or the base station forwards the data packet according to the single-hop transmission mode of the scenario 1, and finally sends the data packet to the user equipment node of the receiving end.

场景六、用户设备到用户设备的多跳传输方案2Scenario 6. Multi-hop transmission scheme from user equipment to user equipment 2

本方案仅适用于静态路由方案，即在发送端用户设备到接收端用户设备的会话建立过程中，确定固定路由，基站为发送端用户设备到中继用户设备的传输，以及中继用户设备到接收端用户设备的传输分配资源。This solution is only applicable to the static routing scheme, that is, during the session establishment process from the user equipment of the sending end to the user equipment of the receiving end, the fixed route is determined, and the base station transmits the user equipment to the relay user equipment, and the user equipment is relayed. The transmission of the user equipment of the receiving end allocates resources.

如图21所示，本发明实施例蜂窝网络中第二种用户设备到用户设备的多跳传输方法包括：As shown in FIG. 21, a multi-hop transmission method of a second user equipment to a user equipment in a cellular network according to an embodiment of the present invention includes:

步骤1：在会话建立过程中，发送端用户设备、基站、中继节点和接收端用户设备建立与该会话相关的静态路由关系。Step 1: During the session establishment process, the sending user equipment, the base station, the relay node, and the receiving end user equipment establish a static routing relationship related to the session.

步骤2：数据包到达后，发送端用户设备向基站发起调度请求，并携带会话标识。基站根据会话标识判断出是多跳传输，基站为发送端用户设备到接收端用户设备多跳传输进行资源分配。Step 2: After the data packet arrives, the transmitting end user equipment initiates a scheduling request to the base station, and carries the session identifier. The base station determines that the multi-hop transmission is performed according to the session identifier, and the base station allocates resources for the multi-hop transmission of the user equipment of the transmitting end to the user equipment of the receiving end.

步骤3：基站通过单播或广播方式将多跳资源分配信息分别通知发送端用户设备、中继节点以及接收端用户设备。Step 3: The base station separately reports the multi-hop resource allocation information to the transmitting end user equipment, the relay node, and the receiving end user equipment by using unicast or broadcast mode.

发送端用户设备保存第一跳发送的资源配置。The source device of the sending end saves the resource configuration sent by the first hop.

中继节点保存第一跳接收资源和第二跳发送资源配置。The relay node saves the first hop receiving resource and the second hop sending resource configuration.

接收端用户设备保存第二跳接收资源配置。The receiving end user equipment saves the second hop receiving resource configuration.

步骤4：发送端用户设备将数据包首先封装成用于物理层传输的传输块，并根据基站指示的第一跳传输资源进行数据传输块的发送。Step 4: The transmitting end user equipment first encapsulates the data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the first hop transmission resource indicated by the base station.

其中，调制编码方式可以是固定或可变的，如果是固定的，发送端用户设备可以不将调制编码方式通知接收端用户设备；如果是可变的，发送端用户设备可以将调制编码方式通知中继节点。The modulation and coding mode may be fixed or variable. If it is fixed, the user equipment at the transmitting end may not notify the user equipment of the receiving end of the modulation and coding mode; if it is variable, the user equipment of the transmitting end may notify the modulation and coding mode. Relay node.

步骤5：中继节点根据步骤3接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。Step 5: The relay node receives the transmission configuration and resource indication information according to step 3, and combines the activation of the self. The session collection sessions determine the collection of received resources.

由于接收端用户设备可能同时激活多个会话session，不同的会话对应的对端设备可能是不同的发送端用户设备(这里基站被看成是特殊功能的用户设备)，因此中继节点可能需要同时对多个发送端用户设备使用的传输资源进行并行接收。Since the receiving end user equipment may activate multiple session sessions at the same time, the peer devices corresponding to different sessions may be different sender user devices (where the base station is regarded as a special function user device), so the relay node may need to be simultaneously The transmission resources used by multiple sender user equipments are received in parallel.

根据实际接收情况(成功或失败)，中继节点使用与接收资源对应的反馈信道资源，向发送端用户设备发送ACK或NACK反馈信息。如果在当前时刻中继节点并行来自不同发送端用户设备的多路传输进行了并行接收，那么中继节点也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the relay node uses the feedback channel resource corresponding to the received resource to send ACK or NACK feedback information to the transmitting end user equipment. If the relay node performs parallel reception in parallel with multiplex transmissions from different transmitting end user equipments at the current moment, the relay node also performs corresponding feedback on the multiplex transmission.

步骤6：中继节点将转发数据包首先封装成用于物理层传输的传输块，并根据基站指示的第二跳资源进行数据传输块的发送。Step 6: The relay node first encapsulates the forwarded data packet into a transport block for physical layer transmission, and performs data transmission block transmission according to the second hop resource indicated by the base station.

其中，调制编码方式可以是固定或可变的，如果是固定的，中继节点可以不将调制编码方式通知接收端用户设备；如果是可变的，中继节点可以将调制编码方式通知接收端用户设备。The modulation and coding mode may be fixed or variable. If it is fixed, the relay node may not notify the receiving end user equipment of the modulation and coding mode; if it is variable, the relay node may notify the receiving end of the modulation and coding mode. User equipment.

比如中继节点可以通过该传输块的控制部分指示该传输块的数据部分使用的调制编码方式，从而实现数据部分调制编码方式动态可变的目的。For example, the relay node can indicate the modulation and coding mode used by the data part of the transport block through the control part of the transport block, thereby realizing the purpose of dynamically changing the data partial modulation and coding mode.

步骤7：接收端用户设备根据步骤3接收到的传输配置与资源指示信息，并结合自身激活的会话集合sessions，确定接收资源集合。接收端用户设备根据数据传输块的控制部分确定数据部分使用的调制编码方式，从而对数据部分进行解调。Step 7: The receiving end user equipment determines the receiving resource set according to the transmission configuration and resource indication information received in step 3, and in combination with the session set sessions activated by itself. The receiving end user equipment determines the modulation and coding mode used by the data part according to the control part of the data transmission block, thereby demodulating the data part.

根据实际接收情况(成功或失败)，接收端用户设备使用与接收资源对应的反馈信道资源，向发送端用户设备发送ACK或NACK反馈信息。如果在当前时刻中继节点并行来自不同发送端用户设备的多路传输进行了并行接收，那么接收端用户设备也要对多路传输进行相应的反馈。According to the actual receiving situation (success or failure), the receiving end user equipment sends the ACK or NACK feedback information to the sending end user equipment by using the feedback channel resource corresponding to the receiving resource. If the multiplex transmission from the different transmitting end user equipments is received in parallel at the current moment, the receiving end user equipment also needs to respond correspondingly to the multiplex transmission.

场景七、用户设备触发的资源去激活方案Scenario 7, the resource deactivation scheme triggered by the user equipment

对于实施例4中针对周期性业务资源与调度方案中，一种情况是在业务结束后资源被释放，另一种场景是，用户设备用户设备可以能由于并关闭或者从服务区域中移出的情况，在这种情况下，用户设备用户设备需要触发基站提前终止资源预分配，从而达到节省无线资源的目的。本实施例以发端用户设备发生“去激活事件”为例进行说明，收端用户设备检测到“去激活事件”的处理过程类似。 For the periodic service resource and scheduling scheme in Embodiment 4, one case is that the resource is released after the service ends, and the other scenario is that the user equipment user equipment can be removed due to or removed from the service area. In this case, the user equipment user equipment needs to trigger the base station to terminate the resource pre-allocation in advance, thereby achieving the purpose of saving radio resources. In this embodiment, the “deactivation event” occurs on the sending user equipment as an example, and the processing procedure in which the receiving user equipment detects the “deactivation event” is similar.

如图22所示，本发明实施例蜂窝网络中去激活的方法包括：As shown in FIG. 22, the method for deactivating in a cellular network according to an embodiment of the present invention includes:

步骤1：通过周期性业务会话激活过程，发送端用户设备、基站和接收端用户设备分别保存关于周期性业务会话的标识，周期、数据包大小等信息。Step 1: Through the periodic service session activation process, the sending user equipment, the base station, and the receiving end user equipment respectively store information about the identifier, period, and packet size of the periodic service session.

步骤2：发送端用户设备按照场景四中记载过程进行数据传输，接收端用户设备按照场景四记载过程进行接收。Step 2: The user equipment at the transmitting end performs data transmission according to the process described in the scenario 4, and the user equipment at the receiving end receives the data according to the process described in the scenario 4.

步骤3：发送端用户设备检测到“去激活事件”从而触发基站提前释放针对周期性业务传输预分配的资源。Step 3: The transmitting end user equipment detects a “deactivation event” to trigger the base station to release the pre-allocated resources for the periodic service transmission in advance.

其中“去激活事件”包括但不限于用户设备用户设备关闭。The "deactivation event" includes, but is not limited to, the user equipment user equipment is turned off.

步骤4：发送端用户设备向基站发送“周期业务去激活指示”触发基站提前释放为本次周期性业务传输预先分配的无线资源，以及与周期性业务相关的上下文信息，上下文信息包括参数配置和有会话相关的临时标识等。Step 4: The sending end user equipment sends a “periodic service deactivation indication” to the base station to trigger the base station to release the pre-allocated radio resources for the periodic service transmission and the context information related to the periodic service, where the context information includes parameter configuration and There are session-related temporary identifiers, etc.

步骤5：基站从发送端用户设备收到指示后，触发周期性业务会话去激活过程，以使发送端用户设备、基站和接收端用户设备分别释放关于周期性业务会话的上行文信息。Step 5: After receiving the indication from the sending user equipment, the base station triggers the periodic service session deactivation process, so that the sending user equipment, the base station, and the receiving end user equipment respectively release the uplink information about the periodic service session.

此外发送端用户设备，基站和接收端用户设备将各自释放针对周期性业务传输的持续资源分配。In addition, the transmitting end user equipment, the base station and the receiving end user equipment will each release a persistent resource allocation for periodic service transmission.

从上述内容可以看出：本发明实施例网络控制设备确定同一区域中进行传输涉及的各设备；以及确定各设备进行传输使用的传输资源，并进行传输资源配置。由于网络控制设备能够对同一区域中进行传输涉及的各设备进行资源配置，从而不需要向发送端配置控制资源，发送端也不需要发送数据之前通知接收端具体的发送资源的位置，优化了资源配置方案，使得资源配置更紧凑，因此与LTE D2D传输方案相比可大大降低时延。It can be seen from the above that the network control device in the embodiment of the present invention determines each device involved in the transmission in the same area; and determines the transmission resource used by each device for transmission, and performs transmission resource configuration. Since the network control device can perform resource configuration on each device involved in the transmission in the same area, it is not necessary to configure the control resource to the transmitting end, and the transmitting end does not need to notify the receiving end of the location of the specific sending resource before sending the data, and optimizes the resource. The configuration scheme makes the resource configuration more compact, so the delay can be greatly reduced compared with the LTE D2D transmission scheme.
