Description

通信方法和装置Communication method and device

技术领域Technical field

本申请实施例涉及通信技术领域，尤其涉及一种通信方法和装置。The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method and device.

背景技术Background technique

在无线通信***中，对于周期业务，为了降低资源开销，降低数据传输时延和节能，通常可以在预先定义好的资源上传输业务，也就是不需要下行控制信息(downlink control information,DCI)动态调度，终端设备即可在预先配置的资源上传输数据。In wireless communication systems, for periodic services, in order to reduce resource overhead, data transmission delay and energy saving, it is usually possible to transmit services on pre-defined resources, that is, no downlink control information (DCI) dynamic By scheduling, the terminal device can transmit data on pre-configured resources.

现有技术中，为了解决由于配置预配置资源后，导致的***资源浪费，且造成终端设备功耗的增加的问题，基站需要对预配置资源进行激活或者去激活处理，并通过***消息(system information，SI)通知终端设备，预配置资源是处于激活状态或者去激活状态。In the prior art, in order to solve the problem of waste of system resources caused by the configuration of pre-configured resources and increase in power consumption of terminal equipment, the base station needs to activate or deactivate the pre-configured resources and pass system messages (system information, SI) informs the terminal device that the pre-configured resource is in the activated or deactivated state.

然而，基站在通过SI消息通知终端设备预配置资源是处于激活状态或者去激活状态时，由于SI消息的数据量较大，导致终端设备在更新SI的过程中的功耗较高。However, when the base station informs the terminal device that the pre-configured resource is in the activated or deactivated state through the SI message, the large amount of data in the SI message results in high power consumption of the terminal device in the process of updating the SI.

发明内容Summary of the invention

本申请提供一种通信方法和装置，能够降低第一设备的功耗，而且能够提高资源的利用率。The present application provides a communication method and device, which can reduce the power consumption of a first device and can improve resource utilization.

第一方面，本申请实施例提供一种通信方法，包括：In the first aspect, an embodiment of the present application provides a communication method, including:

第一设备接收第二设备发送的第一信息；所述第一信息包含于下行控制信息DCI中，和/或所述第一信息包含于所述下行控制信息DCI调度的数据中；The first device receives the first information sent by the second device; the first information is included in the downlink control information DCI, and/or the first information is included in the data scheduled by the downlink control information DCI;

所述第一信息包括第一指示信息，所述第一设备根据所述第一指示信息确定是否能够使用第一资源传输信息；和/或，所述第一信息包括第二指示信息，所述第一设备根据所述第二指示信息确定所述第二设备是否成功接收第二信息，所述第二信息包括在第二资源上传输的信息。The first information includes first indication information, and the first device determines whether the first resource can be used to transmit information according to the first indication information; and/or, the first information includes second indication information, The first device determines whether the second device successfully receives the second information according to the second indication information, where the second information includes information transmitted on the second resource.

其中，第一资源和第二资源均为预先配置的资源，其中，预先配置的上行资源(preconfigured uplink resource,PUR)仅是一种示例性命名，其实质是网络设备通过配置第一资源，终端设备可以在不需要网络设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输，该资源也可以命名为其他名称，如配置授权资源，应理解，若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能，也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便，本申请实施例中将第一资源统一称为预配置资源。Among them, the first resource and the second resource are both pre-configured resources.

The resource can also be named other names, such as configuring authorized resources. It should be understood that if the authorized resources are configured The functions implemented by the first resource in the embodiment of the present application can also be realized, and the configured authorized resource can also be understood as the first resource in the embodiment of the present application. For the convenience of description, the first resource is collectively referred to as a pre-configured resource in the embodiment of the present application.

在上述方案中，由于该第一信息包含于DCI和/或DCI调度的数据中，且DCI的CRC由RA-RNTI进行加扰，因此可以减少第一设备盲检下行控制信道的次数，降低第一设备的功率。另外，由于复用了现有DCI和/或DCI调度的数据，因此可以提高资源的利用率。进一步地，在第一信息中包括有第一指示信息，第一设备可以根据第一指示信息确定是否能够使用第一资源传输信息，这样不仅可以提高资源的利用率，而且可以降低第一设备的功耗。另外，在第一信息中包括有第二指示信息，第一设备可以确定出预配置资源上传输的信息的确认信息(Acknowledgment，ACK)和否认信息(Negative Acknowledgement，NACK)反馈，即获知该信息是否被网络设备成功接收，从而可以降低丢包率，提高传输的成功概率。In the above solution, since the first information is included in the data scheduled by DCI and/or DCI, and the CRC of the DCI is scrambled by RA-RNTI, the number of blind detections of the downlink control channel by the first device can be reduced, and the number of The power of a device.

Further, the first information includes first indication information, and the first device can determine whether the first resource can be used to transmit information according to the first indication information.

Those of ordinary skill in the art will know that with the network With the evolution of architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

值得注意的是，本申请实施例中均以第一设备为终端设备，第二设备为网络设备为例进行说明，在实际应用中，第一设备和第二设备也可以是其他设备，如第一设备可以为具有接收能力的设备，第二设备为具有发送能力的设备。It is worth noting that in the embodiments of this application, the first device is the terminal device and the second device is the network device as an example. In actual applications, the first device and the second device may also be other devices, such as the first device and the second device. One device may be a device with receiving capability, and the second device may be a device with sending capability.

下面首先针对本申请实施例适用场景进行简要说明。The following first briefly describes the application scenarios of the embodiments of the present application.

对于周期性业务，为了降低资源开销，降低数据传输时延和节能，可在预先定义好的资源上传输业务，也就是不需要DCI动态调度，终端设备可以在预先配置的资源上传输上行信息，其中，上行信息可以包括数据、控制信息和参考信号中的一种或多种，对于上行信息的具体形式，此处不做具体限定。另外，需要进行说明的是，预先配置的上行资源(preconfigured uplink resource,PUR)仅是一种示例性命名，其实质是网络设备通过配置第一资源，终端设备可以在不需要网络设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输，该资源也可以命名为其他名称，如配置授权资源，应理解，若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能，也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便，本申请实施例中将第一资源统一称为预配置资源。For periodic services, in order to reduce resource overhead, data transmission delay and energy saving, services can be transmitted on pre-defined resources, that is, DCI dynamic scheduling is not required, and terminal devices can transmit uplink information on pre-configured resources. The uplink information may include one or more of data, control information, and reference signals. The specific form of the uplink information is not specifically limited here. In addition, it should be noted that the preconfigured uplink resource (PUR) is only an exemplary naming, and its essence is that by configuring the first resource of the network device, the terminal device can dynamically schedule or schedule the network device without the need for the network device. In the case of downlink control information scheduling, the uplink information is transmitted on the first resource. The resource can also be named other names, such as configuring authorized resources. It should be understood that if the authorized resources are configured, the first resource in the embodiment of this application can also be implemented. The function implemented by a resource can also be understood as the first resource in the embodiment of the application. For the convenience of description, the first resource is collectively referred to as a pre-configured resource in the embodiment of the present application.

其中，预配置资源一般是按照一定的周期配置的，因此，在使能预配置传输的预配置资源之后，该预配置资源均预留给预配置资源传输。这会带来两方面的制约和限制：1、由于***资源是有限的，如果大量配置为预配置资源，将会影响其他终端设备的资源使用；2、对于信道质量较差的终端设备，其在使用预配置资源时失败率较高，但是该预配置资源却仍然被该终端设备所占用。上述两方面的限制均会导致***资源的浪费，使得终端设备功耗的增加。为了解决上述问题，网络设备需要对预配置资源进行激活或者去激活处理，并通过***消息(system information，SI)通知终端设备，预配置资源是处于激活状态还是去激活状态。然而，网络设备在通过SI消息通知终端设备预配置资源是处于激活状态或者去激活状态时，由于SI消息的数据量较大，导致终端设备在更新SI的过程中的功耗较高。另外，终端设备如何确定出预配置资源上传输的信息是否被网络设备成功接收，也是本申请实施例需要解决的技术问题。Among them, the pre-configured resources are generally configured according to a certain period. Therefore, after the pre-configured resources for pre-configured transmission are enabled, the pre-configured resources are all reserved for pre-configured resource transmission. This will bring two constraints and restrictions: 1. Because system resources are limited, if a large number of configurations are pre-configured resources, it will affect the resource usage of other terminal devices; 2. For terminal devices with poor channel quality, other The failure rate is high when using pre-configured resources, but the pre-configured resources are still occupied by the terminal device. The above two limitations will lead to a waste of system resources and increase the power consumption of terminal equipment. In order to solve the above problem, the network device needs to activate or deactivate the pre-configured resource, and notify the terminal device through a system information (SI) whether the pre-configured resource is in an activated state or a deactivated state. However, when the network device notifies the terminal device that the pre-configured resource is in the activated state or the deactivated state through the SI message, the large amount of data in the SI message results in high power consumption of the terminal device in the process of updating the SI. In addition, how the terminal device determines whether the information transmitted on the pre-configured resource is successfully received by the network device is also a technical problem to be solved in the embodiment of the present application.

本申请实施例中考虑到上述问题，提出了一种通信方法，第一设备通过接收第二设备发送的第一信息，DCI包含该第一信息，和/或，DCI调度的数据包含该第一信息，该DCI的CRC由RA-RNTI进行加扰，在第一信息中包括第一指示信息，第一设备根据第一指示信息确定是否能够使用第一资源传输信息；和/或，在第一信息中包括第二指示信息，第一设备根据第二指示信息确定第二设备是否成功接收第二信息，该第二信息包括在第二资源上传输的信息。由于该第一信息包含于DCI和/或DCI调度的数据中，且DCI的CRC由RA-RNTI进行加扰，在第一信息中包括有第一指示信息，第一设备在根据第一指示信息确定是否能够使用第一资源传输信息，可以降低第一设备的功耗。另外，在第一信息中包括有第二指示信息，第一设备可以确定出预配置资源上传输的信息的确认信息(Acknowledgment，ACK)和否认信息(Negative Acknowledgement，NACK)反馈，即获知该信息是否被网络设备成功接收。In the embodiments of this application, considering the above problems, a communication method is proposed. The first device receives the first information sent by the second device, and the DCI includes the first information, and/or the data scheduled by the DCI includes the first information. Information, the CRC of the DCI is scrambled by RA-RNTI, the first information includes first indication information, and the first device determines whether the first resource can be used to transmit information according to the first indication information; and/or, in the first The information includes second indication information, and the first device determines whether the second device successfully receives the second information according to the second indication information, and the second information includes the information transmitted on the second resource. Since the first information is included in the data scheduled by DCI and/or DCI, and the CRC of DCI is scrambled by RA-RNTI, the first information includes the first indication information, and the first device is in accordance with the first indication information Determining whether the first resource can be used to transmit information can reduce the power consumption of the first device. In addition, the first information includes the second indication information, and the first device can determine the acknowledgement information (Acknowledgment, ACK) and negative information (Negative Acknowledgement, NACK) feedback of the information transmitted on the pre-configured resource, that is, to know the information Whether it is successfully received by the network device.

下面，通过具体实施例对本申请的技术方案进行详细说明。需要说明的是，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。Hereinafter, the technical solution of the present application will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

图2为本申请通信方法的一种信令交互图。本实施例以通信***中的终端设备和网络设备之间的信息交互进行说明。在上述图1所示***架构的基础上，如图2所示，在本实施例中，该通信方法可以包括如下步骤：Figure 2 is a signaling interaction diagram of the communication method of this application. This embodiment is described with the information interaction between the terminal device and the network device in the communication system. Based on the system architecture shown in FIG. 1, as shown in FIG. 2, in this embodiment, the communication method may include the following steps:

步骤201：第二设备确定第一信息。Step 201: The second device determines the first information.

其中，该第一信息包含于DCI中，也就是说，DCI包含第一信息，和/或DCI调度的数据包含第一信息。Wherein, the first information is included in the DCI, that is, the DCI includes the first information, and/or the data scheduled by the DCI includes the first information.

具体的，第一信息可以包含于DCI中，或者，第一信息可以包含于DCI调度的数据中，或者，该第一信息也可以包含于DCI以及DCI调度的数据中。其中，DCI调度的数据也可以为DCI调度的数据信道。Specifically, the first information may be included in the DCI, or the first information may be included in the data scheduled by the DCI, or the first information may also be included in the DCI and the data scheduled by the DCI. Among them, the data scheduled by the DCI may also be a data channel scheduled by the DCI.

在一种可能的实现方式中，上述的DCI的CRC由RA-RNTI进行加扰。由于目前RA-RNTI加扰的DCI可以用于调度随机接入响应，本申请实施例中通过复用该DCI的冗余字段，可以节省网络资源，有利于降低网络负担。In a possible implementation manner, the CRC of the aforementioned DCI is scrambled by RA-RNTI. Since the current RA-RNTI scrambled DCI can be used to schedule random access responses, in the embodiment of the present application, by multiplexing the redundant field of the DCI, network resources can be saved, which is beneficial to reducing network burden.

在另一种可能的实现方式中，上述的DCI的CRC也可以由***信息-无线网络临时标识(system information-RNTI，SI-RNTI)进行加扰。通过复用SI-RNTI可以减少第一设备监测RNTI的数量，不仅可以节省终端设备的功耗，降低实现的复杂度，而且可以减少第二设备确定的RNTI的数量，降低了第二设备的实现复杂度。In another possible implementation manner, the CRC of the aforementioned DCI may also be scrambled by the system information-radio network temporary identification (system information-RNTI, SI-RNTI). By multiplexing SI-RNTI, the number of RNTIs monitored by the first device can be reduced, which not only saves the power consumption of the terminal device and reduces the complexity of implementation, but also reduces the number of RNTIs determined by the second device and reduces the implementation of the second device the complexity.

在一种可能的实现方式中，在第一信息包含于DCI调度的数据DCI调度的数据包含第一信息时，前述DCI调度的数据包括随机接入响应(randon access response；RAR)和/或媒体接入控制子头。In a possible implementation manner, when the first information is included in the data scheduled by DCI and the data scheduled by DCI includes the first information, the aforementioned DCI scheduled data includes random access response (RAR) and/or media Access control subheader.

具体的，DCI调度的数据可以仅包括RAR，也可以仅包括媒体接入控制子头，还可以同时包括RAR和媒体接入控制子头。其中，RAR可以为介质访问控制层(media access control；MAC)RAR。Specifically, the data scheduled by the DCI may include only RAR, may also include only the medium access control subheader, or may also include both RAR and medium access control subheader. Among them, RAR may be a media access control layer (media access control; MAC) RAR.

在一种可能的实现方式中，第一信息包含于DCI，即DCI包含第一信息，该第一信息包含于DCI的第一字段中，其中，该第一字段包括以下一个或多个字段：物理上行控制信道的传输功率控制命令字段((transmit power control，TPC)command for(physical uplink control channel，PUCCH))、混合自动重传请求(hybrid automatic repeat request，HARQ)进程号字段、新数据指示(new data indicator，NDI)字段、下行链路传输资源索引(downlink assignment index，DAI)字段和混合自动重传请求-确认信息资源偏移(HARQ-ACK resource offset)字段。In a possible implementation manner, the first information is included in the DCI, that is, the DCI includes the first information, and the first information is included in the first field of the DCI, where the first field includes one or more of the following fields: The transmission power control command field of the physical uplink control channel ((transmit power control, TPC) command for (physical uplink control channel, PUCCH)), hybrid automatic repeat request (HARQ) process number field, new data indication (new data indicator, NDI) field, downlink transmission resource index (downlink assignment index, DAI) field, and hybrid automatic repeat request-acknowledgement information resource offset (HARQ-ACK resource offset) field.

步骤202：第二设备向第一设备发送第一信息。Step 202: The second device sends the first information to the first device.

在本步骤中，第二设备在确定出第一信息后，将确定出的第一信息发送给第一设备。In this step, after determining the first information, the second device sends the determined first information to the first device.

示例性的，第一设备在n+k子帧后的第m个RAR窗口中监测承载DCI的物理下行控制信道(Physical Downlink Control Channel；PDCCH)，以接收第一信息；其中，n为第一资源或第二资源传输的最后一个子帧，k为大于或等于零的整数，m为大于或等于1的整数。Exemplarily, the first device monitors the physical downlink control channel (Physical Downlink Control Channel; PDCCH) carrying DCI in the m-th RAR window after n+k subframes to receive the first information; where n is the first In the last subframe of the resource or the second resource transmission, k is an integer greater than or equal to zero, and m is an integer greater than or equal to 1.

其中，m的值可以为1、2或3等，以m为1为例，第一设备将监测预配置的第一资源或第二资源传输结束加k个子帧后的第一个RAR窗口。图3为第一设备监测PDCCH的示意图，以m为1为例，第一设备将在n+k子帧后的第1个RAR窗口中监测承载DCI的PDCCH，也即在RAR窗口0中监测PDCCH。The value of m can be 1, 2, or 3, etc. Taking m as 1 as an example, the first device will monitor the first RAR window after the pre-configured transmission of the first resource or the second resource is completed plus k subframes. Figure 3 is a schematic diagram of the first device monitoring PDCCH, taking m as an example, the first device will monitor the PDCCH carrying DCI in the first RAR window after n+k subframes, that is, monitor in RAR window 0 PDCCH.

另外，在一种可能的实现方式中，RAR窗口所对应的覆盖增强等级与第一设备的覆盖增强等级相同，或者RAR窗口所对应的覆盖增强模式与第一设备的覆盖增强模式相同。In addition, in a possible implementation manner, the coverage enhancement level corresponding to the RAR window is the same as the coverage enhancement level of the first device, or the coverage enhancement mode corresponding to the RAR window is the same as the coverage enhancement mode of the first device.

例如：覆盖增强模式A(CE Mode A)或覆盖增强等级为0或1的第一设备会监测覆盖增强等级为0或1的RAR窗口，覆盖增强模式B(CE Mode B)或覆盖增强等级为2或3的第一设备会监测覆盖增强等级为2或3的RAR窗口。For example: Coverage enhancement mode A (CE Mode A) or the first device with coverage enhancement level 0 or 1 will monitor the RAR window with coverage enhancement level 0 or 1, and coverage enhancement mode B (CE Mode B) or coverage enhancement level is The first device with 2 or 3 will monitor the RAR window with coverage enhancement level 2 or 3.

步骤203：第一信息包括第一指示信息，第一设备根据第一指示信息确定是否能够使用第一资源传输信息；和/或，第一信息包括第二指示信息，第一设备根据第二指示信息确定第二设备是否成功接收第二信息；第二信息包括在第二资源上传输的信息。Step 203: The first information includes first indication information, and the first device determines whether the first resource can be used to transmit information according to the first indication information; and/or, the first information includes second indication information, and the first device according to the second indication The information determines whether the second device successfully receives the second information; the second information includes the information transmitted on the second resource.

具体的，该第一信息中可以仅包括第一指示信息，也可以仅包括第二指示信息，还可以同时包括第一指示信息和第二指示信息。在一种可能的实现方式中，在第一信息中包括有第一指示信息，第一设备将根据该第一指示信息确定是否能够使用第一资源传输信息，也即确定是否在第一资源上传输信息，其中，第一资源为预配置资源，进一步地，第一资源可以为预先配置的时频资源。Specifically, the first information may include only the first indication information, or may only include the second indication information, or may also include both the first indication information and the second indication information. In a possible implementation manner, the first information includes first indication information, and the first device will determine whether the first resource can be used to transmit information according to the first indication information, that is, whether it is on the first resource To transmit information, where the first resource is a pre-configured resource, and further, the first resource may be a pre-configured time-frequency resource.

示例性的，可以理解的是，使用第一资源传输信息意为使用该第一资源进行如下至少一个信息的传输：数据、控制信息和参考信令，也可以理解为激活或使能第一资源，或者理解为指示第一资源为激活状态或使能状态；不使用第一资源传输信息意为不使用该第一资源进行如下至少一个信息的传输：数据、控制信息和参考信令，也可以理解为去激活或去使能第一资源，或者理解为指示第一资源为去激活状态或去使能状态。Exemplarily, it can be understood that using the first resource to transmit information means using the first resource to transmit at least one of the following information: data, control information, and reference signaling. It can also be understood as activating or enabling the first resource , Or understood as indicating that the first resource is in an active state or an enabled state; not using the first resource to transmit information means not using the first resource to transmit at least one of the following information: data, control information, and reference signaling, or It is understood as deactivating or de-enabling the first resource, or as indicating that the first resource is in a deactivated state or a de-enabled state.

例如：第一设备可以通过第一指示信息确定出是使用第一资源进行信息的传输，还是不使用第一资源进行信息的传输，或者第一设备可以通过第一指示信息确定第一资源是处于激活状态还是处于去激活状态，或者第一设备可以通过第一指示信息确定第一资源是处于使能状态还是处于去使能状态，从而确定是否能够使用第一资源传输信息。如：若第一资源处于激活状态，则第一设备将可以使用预先配置好的第一资源传输信息，若第一资源处于去激活状态，则第一设备将不使用预先配置好的第一资源传输信息。For example, the first device may determine whether to use the first resource for information transmission or not to use the first resource for information transmission through the first indication information, or the first device may use the first indication information to determine whether the first resource is in The activated state is still in the deactivated state, or the first device may determine whether the first resource is in the enabled state or the disabled state through the first indication information, so as to determine whether the first resource can be used to transmit information. For example: if the first resource is in the activated state, the first device will be able to use the pre-configured first resource to transmit information, if the first resource is in the deactivated state, the first device will not use the pre-configured first resource transmit information.

在另一种可能的实现方式中，在第一信息中包括有第二指示信息，第一设备将根据该第二指示信息确定第二设备是否成功接收第二信息，该第二信息包括在第二资源上传输的信息。In another possible implementation manner, the first information includes second indication information, and the first device will determine whether the second device successfully receives the second information according to the second indication information, and the second information is included in the second indication information. 2. Information transmitted on resources.

其中，第一设备根据该第二指示信息确定第二设备是否成功接收第二信息，可以理解为第一设备根据第二指示信息确定第二信息的状态，其中，第二信息的状态包括第二设备成功接收了该第二信息的状态和第二设备未成功接收该第二信息的状态。The first device determines whether the second device successfully receives the second information according to the second indication information. It can be understood that the first device determines the status of the second information according to the second indication information, where the status of the second information includes the second information. The status of the device successfully receiving the second information and the status of the second device not successfully receiving the second information.

具体的，第二资源为预配置资源，进一步地，第二资源可以为预先配置的时频资源。其中，第二资源和第一资源可以相同，也可以不同。示例性的，第一设备可以通过第二指示信息确定第二设备是否成功接收在第二资源上传输的信息，其中，第二指示信息可以为ACK、NACK或重传。例如：若第二指示信息为ACK，则第一设备确定第二设备成功接收第二信息，若第二指示信息为NACK或重传，则第一设备确定第二设备未成功接收第二信息。Specifically, the second resource is a pre-configured resource. Further, the second resource may be a pre-configured time-frequency resource. Wherein, the second resource and the first resource may be the same or different. Exemplarily, the first device may determine whether the second device successfully receives the information transmitted on the second resource through the second indication information, where the second indication information may be ACK, NACK or retransmission. For example: if the second indication information is ACK, the first device determines that the second device successfully receives the second information, and if the second indication information is NACK or retransmission, the first device determines that the second device has not successfully received the second information.

在又一种可能的实现方式中，在第一信息中包括有第一指示信息和第二指示信息，第一设备将根据第一指示信息确定是否能够使用第一资源传输信息，并且根据第二指示信息确定第二设备是否成功接收第二信息。其中，第一设备根据第一指示信息确定是否能够使用第一资源传输信息，以及根据第二指示信息确定第二设备是否成功接收第二信息的方式，与前述实施例中的方式类似，此处不再赘述。In another possible implementation manner, the first information includes the first indication information and the second indication information, the first device will determine whether the first resource can be used to transmit information according to the first indication information, and according to the second indication information The indication information determines whether the second device successfully receives the second information. The manner in which the first device determines whether the first resource can be used to transmit information according to the first indication information, and the manner in which the second device successfully receives the second information according to the second indication information is similar to the manner in the foregoing embodiment, here No longer.

在上述各实施例的基础上，可以理解的是，由于第一信息中可以仅包括有第一指示信息，也可以仅包括有第二指示信息，也可以同时包括有第一指示信息和第二指示信息，因此，为了使第一设备能够正确的解析出第一信息中所包含的指示信息，DCI和/或DCI调度的数据中还可以包括第三指示信息，其中，该第三指示信息用于指示第一信息中所包含的指示信息。On the basis of the foregoing embodiments, it can be understood that, since the first information may include only the first indication information, may also include only the second indication information, or may include both the first indication information and the second indication information. Indication information. Therefore, in order to enable the first device to correctly parse out the indication information contained in the first information, the DCI and/or DCI scheduled data may also include third indication information, wherein the third indication information is used To indicate the instruction information contained in the first information.

具体的，在第一信息包含于DCI，即DCI包含第一信息，该DCI中还包括有第三指示信息；在第一信息包含于DCI调度的数据中，即DCI调度的数据包含第一信息，该DCI调度的数据中还包括有第三指示信息，在第一信息包含于DCI以及DCI调度的数据中，即DCI和DCI调度的数据中同时包含第一信息，该DCI和DCI调度的数据中还包括有第三指示信息。Specifically, when the first information is included in the DCI, that is, the DCI includes the first information, and the DCI also includes the third indication information; when the first information is included in the data scheduled by the DCI, that is, the data scheduled by the DCI includes the first information The DCI scheduled data also includes third indication information. The first information is included in the DCI and the DCI scheduled data, that is, the DCI and the DCI scheduled data also include the first information, the DCI and the DCI scheduled data It also includes third instruction information.

另外，上述的第三指示信息还可以承载于***消息中，或者可以承载于无线资源控制指令(radio resource control，RRC)和/或媒体接入控制信令(media access control control element，MAC CE)中。需要说明的是，上述承载也可以理解为包含于，即上述的第三指示信息还可以包含于***消息，或者可以包含于RRC和/或MAC CE。In addition, the above-mentioned third indication information can also be carried in system messages, or can be carried in radio resource control commands (radio resource control, RRC) and/or media access control signaling (media access control control element, MAC CE) in. It should be noted that the above-mentioned bearer may also be understood as being included, that is, the above-mentioned third indication information may also be included in the system message, or may be included in the RRC and/or MAC CE.

其中，上述的第三指示信息可以用于指示DCI中和/或DCI调度的数据中是否包括有第一信息，也就是说，该第三指示信息可以用于指示DCI中是否包括有第一信息，或者用于指示DCI调度的数据中是否包括有第一信息，或者用于指示DCI中以及DCI调度的数据中是否包括有第一信息。在一种可能的实现方式中，可以在DCI中采用1bit表示第三指示信息，以指示该DCI中是否包括有第一信息，或者可以在DCI调度的数据中采用1bit表示第三指示信息，以指示DCI调度的数据中是否包括有第一信息，或者，还可以在DCI中和DCI调度的数据中分别采用1bit表示第三指示信息，以指示DCI调度的数据中是否包括有第一信息。例如：在第三指示信息为“0”时，指示DCI和/或DCI调度的数据中不包括第一信息，在第三指示信息为“1”时，指示DCI和/或DCI调度的数据中包括第一信息。当然，该第三指示信息也可以采用其他方式进行表示，如采用不同的标识符来指示DCI和/或DCI调度的数据中是否包括第一信息。又如：在采用2bit表示第三指示信息时，在第三指示信息为“00”时，指示DCI和/或DCI调度的数据中不包括第一信息。The above-mentioned third indication information may be used to indicate whether the DCI and/or the data scheduled by the DCI includes the first information, that is, the third indication information may be used to indicate whether the DCI includes the first information , Or used to indicate whether the DCI scheduled data includes the first information, or used to indicate whether the DCI and the DCI scheduled data include the first information. In a possible implementation manner, 1 bit may be used in the DCI to indicate the third indication information to indicate whether the DCI includes the first information, or 1 bit may be used in the DCI scheduled data to indicate the third indication information, to Indicate whether the first information is included in the data scheduled by the DCI, or one bit may be used to represent the third indication information in the DCI and the data scheduled by the DCI, respectively, to indicate whether the first information is included in the data scheduled by the DCI. For example: when the third indication information is "0", the data indicating DCI and/or DCI scheduling does not include the first information, and when the third indication information is "1", it indicates DCI and/or DCI scheduling data Including the first information. Of course, the third indication information may also be expressed in other ways, for example, a different identifier is used to indicate whether the DCI and/or DCI scheduled data includes the first information.

The data includes the first information. Or, when the third indication information is "00", the data indicating the DCI and/or DCI scheduling includes the first information.

进一步地，若第三指示信息指示DCI和/或DCI调度的数据中包括有第一信息，则该第三指示信息还用于指示该第一信息中所包含的指示信息，即第三指示信息用于指示第一信息中包括第一指示信息，或者，第三指示信息用于指示该第一信息中包括有第二指示信息，或者，该第三指示信息用于指示该第一信息中同时包括有第一指示信息和第二指示信息。例如：在第三指示信息采用2bit表示时，在第三指示信息为“01”时，指示第一信息中包括有第一指示信息，在第三指示信息为“10”时，指示第一信息中包括有第二指示信息，在第三指示信息为“11”时，指示第一信息中包括有第一指示信息和第二指示信息。当然，该第三指示信息也可以采用其他方式进行表示，如采用不同的标识符来指示不同的指示信息。Further, if the third indication information indicates that the DCI and/or DCI scheduled data includes the first information, the third indication information is also used to indicate the indication information contained in the first information, that is, the third indication information It is used to indicate that the first information includes the first indication information, or the third indication information is used to indicate that the first information includes the second indication information, or the third indication information is used to indicate that the first information includes both It includes first indication information and second indication information.
