传输数据的方法、装置及***Method, device and system for transmitting data

技术领域Technical field

本发明实施例涉及通信技术，尤其涉及一种传输数据的方法、装置及***。Embodiments of the present invention relate to communication technologies, and in particular, to a method, an apparatus, and a system for transmitting data.

背景技术Background technique

频谱资源是无线通信的基础。根据联邦通讯委员会(Federal Communications Commission，简称：FCC)最新发布的国际频谱***，未授权(unlicensed)频谱资源要多于授权频谱资源。由于目前在未授权频谱上对无线通信***和运营商的使用没有约束，因此存在多种通信***、多个运营商都想要占用相同信道的情况。按照ETSI EN 301893目前的规定，无线通信设备在未授权频谱上使用时需要遵循欧洲电信标准协会(European Telecommunications Standards Institute，简称：ETSI)发布的ETSI EN 301 893标准中的先听后说(Listen Before Talk，简称：LBT)规则。LBT规则即无线通信设备在使用未授权频谱之前，首先监听未授权频谱的信道是否空闲，如果信道空闲则可以使用该未授权频谱的信道传输数据。无线通信设备可以通过能量检测执行信道空闲评估(Clear Channel Assessment，简称：CCA)。Spectrum resources are the basis of wireless communications. According to the latest international spectrum white paper released by the Federal Communications Commission (FCC), unlicensed spectrum resources are more than licensed spectrum resources. Since there is currently no constraint on the use of wireless communication systems and operators on the unlicensed spectrum, there are multiple communication systems in which multiple operators want to occupy the same channel. According to the current regulations of ETSI EN 301893, wireless communication equipment is required to follow the ETSI EN 301 893 standard issued by the European Telecommunications Standards Institute (ETSI) when it is used on the unlicensed spectrum (Listen Before) Talk, referred to as: LBT) rules. The LBT rule is that the wireless communication device first listens to whether the channel of the unlicensed spectrum is idle before using the unlicensed spectrum, and can transmit data using the channel of the unlicensed spectrum if the channel is idle. The wireless communication device can perform a Clear Channel Assessment (CCA) by energy detection.

长期演进(Long Term Evolution，简称：LTE)***中从基站(Evolved Node B，简称：eNodeB)向用户设备(User Equipment，简称：UE)发送的链路称为下行链路，从UE向eNodeB发送的链路称为上行链路。eNodeB发送给UE的数据在物理层通过物理下行共享信道(physical downlink shared channel，简称：PDSCH)承载，UE发送给eNodeB的数据在物理层通过物理上行共享信道(physical uplink shared channel，简称：PUSCH)承载。eNodeB通过物理下行控制信道(physical downlink control channel，简称：PDCCH)或增强的物理下行控制信道(enhanced physical downlink control channel，简称：ePDCCH)向UE指示在PDSCH和/或PUSCH上使用的频谱资源、传输方式。可见，UE的任何一次上行传输所使用的频谱资源都是由eNodeB预先分配好的。 The link sent from the Evolved Node B (eNodeB) to the user equipment (User Equipment, UE for short) in the Long Term Evolution (LTE) system is called downlink, and is sent from the UE to the eNodeB. The link is called the uplink. The data sent by the eNodeB to the UE is carried by the physical downlink shared channel (PDSCH) at the physical layer, and the data sent by the UE to the eNodeB is physically uplink shared channel (PUSCH) at the physical layer. Hosted. The eNodeB indicates the spectrum resource and the transmission used on the PDSCH and/or the PUSCH to the UE through a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH). the way. It can be seen that the spectrum resources used by any uplink transmission of the UE are pre-allocated by the eNodeB.

但是，将未授权频谱作为LTE***的运营频谱时，eNodeB对于UE是否可以通过监听未授权频谱的信道获得在预期时刻发送上行数据的机会并不能“未卜先知”。UE判断是否可占用未授权频谱的信道发送数据取决于其对未授权频谱的信道是否空闲的检测结果，只有确定未授权频谱的信道是空闲的情况下，才可以占用该信道发送数据。当UE从检测起始时间经过预设评估时间后评估到不能占用未授权频谱的信道发送数据，则需要执行“延长CCA”的检测，延长CCA的检测时间长度为一个CCA时间长度的N倍。如果eNodeB在未授权频谱上对UE做了上行调度，期望UE在子帧n使用预先分配的频谱资源发送上行数据，但UE实际在子帧n发送上行数据时，检测到资源被占用而无法按照eNodeB的指示完成预期操作。这样，eNodeB针对UE的上行调度就成为一次无效资源分配，而且eNodeB对已经分配给UE的资源并不会同时分配给其他UE，而该UE由于没有占用上信道而不能按照调度指示发送上行数据，造成已分配频谱资源的浪费，从而导致通信***的传输效率降低。However, when the unlicensed spectrum is used as the operating spectrum of the LTE system, the eNodeB cannot obtain an opportunity to transmit uplink data at an expected time by monitoring the channel of the unlicensed spectrum. The UE determines whether the channel transmission data of the unlicensed spectrum can be occupied depends on whether the channel of the unlicensed spectrum is idle or not. Only when the channel determining the unlicensed spectrum is idle, the channel can transmit the data. When the UE evaluates the channel transmission data that cannot occupy the unlicensed spectrum after the preset start evaluation time, the UE needs to perform the “extended CCA” detection to extend the detection time length of the CCA to N times the length of one CCA. If the eNodeB performs uplink scheduling on the UE on the unlicensed spectrum, the UE is expected to use the pre-allocated spectrum resource to transmit the uplink data in the subframe n. However, when the UE actually sends the uplink data in the subframe n, the detected resource is occupied and cannot be used. The indication of the eNodeB completes the intended operation. In this way, the eNodeB's uplink scheduling for the UE becomes an invalid resource allocation, and the eNodeB does not allocate the resources that have been allocated to the UE to other UEs at the same time, and the UE cannot send the uplink data according to the scheduling indication because the uplink channel is not occupied. This causes waste of allocated spectrum resources, resulting in reduced transmission efficiency of the communication system.

具体实施方式detailed description

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

图1为本发明传输数据的方法的一个实施例的流程图，如图1所示，本实施例的方法可以包括：FIG. 1 is a flowchart of an embodiment of a method for transmitting data according to the present invention. As shown in FIG. 1, the method in this embodiment may include:

步骤101、第一设备确定评估共享信道是否处于空闲状态的起始时间；Step 101: The first device determines a start time for evaluating whether the shared channel is in an idle state.

本发明中的第一设备可以是UE，与第二设备eNodeB基于未授权频谱进行通信，未授权频谱即为所述共享信道。可选的，通信***中的宏基站(Macro eNodeB)和微基站(Pico eNodeB)也可以作为本发明中的第一设备和第二设备，而且宏基站和微基站可以交替充当第一设备和第二设备。可选的，通信***中使用共享信道通信的设备都可以充当第一设备或者第二设备。本实施例中第一设备要通过共享信道进行通信，需要先采用LBT规则检测共享信道是否空闲，只有空闲状态的共享信道才是可以占用并进行通信的。第一设备确定共享信道是否空闲的原则是：如果第一设备从评估共享信道的空闲状态的起始时间开始，到预设评估时间的结束时刻，检测到共享信道空闲，则可判断共享信道为空闲状态并占用所述共享信道发送数据；如果第一设备从评估共享信道的空闲状态的起始时间开始，到预设评估时间的结束时刻，检测到共享信道被占用，则判断当前不能占用所述共享信道发送数据，此时，第一设备需要从预设评估时间的结束时刻开始，继续评估共享信道是否空闲。另一方面，UE发送数据采用的资源是由eNodeB预先分配的，该资源的频段和时间都是确定的，如果UE在要使用该资源发送数据的时候才开始评估共享信道的空闲状态，这样很有可能由于共享信道被占用而无法在确定的时间使用该资源按照调度指示发送数据。The first device in the present invention may be a UE, and the second device eNodeB communicates based on the unlicensed spectrum, and the unlicensed spectrum is the shared channel. Optionally, a macro base station (Macro eNodeB) and a micro base station (Pico eNodeB) in the communication system may also be used as the first device and the second device in the present invention, and the macro base station and the micro base station may alternately serve as the first device and the first device. Two devices. Alternatively, devices in the communication system that use shared channel communication may serve as the first device or the second device. In this embodiment, the first device needs to communicate through the shared channel, and the LBT rule needs to be used to detect whether the shared channel is idle. Only the shared channel in the idle state can occupy and communicate. The first device determines whether the shared channel is idle: if the first device detects that the shared channel is idle from the start time of evaluating the idle state of the shared channel to the end time of the preset evaluation time, the shared channel may be determined as An idle state and occupying the shared channel to transmit data; if the first device detects that the shared channel is occupied from the start time of evaluating the idle state of the shared channel to the end time of the preset evaluation time, determining that the shared channel cannot be occupied currently The shared channel transmits data. At this time, the first device needs to continue to evaluate whether the shared channel is idle, starting from the end time of the preset evaluation time. On the other hand, the resource used by the UE to transmit data is pre-allocated by the eNodeB, and the frequency band and time of the resource are determined. If the UE uses the resource to send data, it starts to evaluate the idle state of the shared channel. It is possible that the shared channel is occupied and the resource cannot be used to transmit data according to the scheduling indication at a determined time.

为了提高第一设备在确定的时间和频率资源上检测到共享信道的空闲状态的概率，并及时占用所述共享信道发送数据，本实施例中第一设备首先确定评估共享信道是否处于空闲状态的起始时间，所述起始时间可以根据第一设备获取到的共享信道可能被释放的时间信息确定，这样第一设备可以将共享信道被释放后的第一时间确定为评估共享信道是否处于空闲状态的起始时间；所述起始时间还可以根据第一设备获取到的自身即将传输数据的时间信息确定，这样第一设备可以将即将传输数据的时间之前的某一个时刻确定为评估共享信道是否处于空闲状态的起始时间。In order to improve the probability that the first device detects the idle state of the shared channel on the determined time and frequency resources, and the data is transmitted in the shared channel in time, the first device in the embodiment first determines whether the shared channel is in an idle state. Starting time, the starting time may be according to the first The time information that the shared channel acquired by the device may be released is determined, so that the first device may determine the first time after the shared channel is released as the start time for evaluating whether the shared channel is in an idle state; the start time may also be The time information of the data to be transmitted by the first device is determined according to the time information of the data to be transmitted by the first device, so that the first device can determine a certain time before the time when the data is to be transmitted as the start time for evaluating whether the shared channel is in an idle state.

步骤102、所述第一设备从所述起始时间开始在预设评估时间内评估所述共享信道是否处于空闲状态；Step 102: The first device, according to the starting time, evaluates whether the shared channel is in an idle state within a preset evaluation time.

第一设备确定出自身从什么时间开始评估共享信道是否处于空闲状态，并在该时间到达时开始进行评估，第一设备在预设评估时间内可持续检测共享信道是否处于空闲状态，只要在这段时间内共享信道的状态一直空闲，即可确定出共享信道为空闲状态，并占用所述共享信道传输数据。预设评估时间可以是由通信***中高层预先配置的一个固定时长，也可以是第一设备和第二设备在通信前提前约定的一个固定时长，第一设备和第二设备均认可需要在该时长内确定共享信道是否处于空闲状态。由于第一设备在共享信道一被释放就开始评估共享信道是否处于空闲状态，或者在即将传输数据的时间之前，提前开始评估共享信道是否处于空闲状态，这样第一设备在预设评估时间内检测出共享信道处于空闲状态的可能性就大，而第一设备一旦占用了共享信道就可以在预期时间使用预先分配的资源传输数据。The first device determines from time when it starts to evaluate whether the shared channel is in an idle state, and starts to perform evaluation when the time arrives, and the first device can continuously detect whether the shared channel is in an idle state within a preset evaluation time, as long as The state of the shared channel is idle for a period of time, and the shared channel is determined to be in an idle state, and the shared channel is used to transmit data. The preset evaluation time may be a fixed duration long pre-configured by the upper layer of the communication system, or may be a fixed duration agreed by the first device and the second device before the communication, and the first device and the second device respectively recognize that the time is required. Determine if the shared channel is idle during the duration. Since the first device starts to evaluate whether the shared channel is in an idle state as soon as the shared channel is released, or starts to evaluate whether the shared channel is in an idle state before the time when the data is to be transmitted, the first device detects in the preset evaluation time. It is highly probable that the shared channel is in an idle state, and the first device can transmit data using the pre-allocated resources at the expected time once the shared channel is occupied.

步骤103、所述第一设备根据评估所述共享信道是否处于空闲状态的评估结果确定是否在所述共享信道上传输数据。Step 103: The first device determines whether to transmit data on the shared channel according to an evaluation result of evaluating whether the shared channel is in an idle state.

根据步骤102第一设备已经对共享信道是否处于空闲状态进行了评估，因此根据评估结果，第一设备就可以确定是否可以在共享信到上传输数据。According to step 102, the first device has evaluated whether the shared channel is in an idle state, so according to the evaluation result, the first device can determine whether data can be transmitted on the shared message.

本实施例，第一设备通过确定评估共享信道是否处于空闲状态的起始时间，提高了第一设备在预设评估时间内检测出共享信道处于空闲状态的概率，使第一设备可以有效地占用共享信道并在所述共享信道上传输数据，避免预先分配资源的浪费，提高通信***的传输效率。In this embodiment, the first device improves the probability that the first device detects that the shared channel is in an idle state in the preset evaluation time by determining the start time of the shared channel in the idle state, so that the first device can effectively occupy the first device. Sharing channels and transmitting data on the shared channel avoids waste of pre-allocated resources and improves transmission efficiency of the communication system.

可选的，在上述步骤101第一设备确定评估共享信道是否处于空闲状态的起始时间之前，所述方法还包括：所述第一设备接收第二设备发送的广播信息、调度指示信息、调度限制信息中的至少一项信息。Optionally, before the first device determines, according to the foregoing step 101, that the shared channel is in the idle state, the method further includes: receiving, by the first device, broadcast information, scheduling indication information, and scheduling sent by the second device. Limit at least one item of information.

具体来讲，第一设备可以通过接收到的广播信息、调度指示信息、调度限制信息中的至少一项信息确定评估共享信道是否处于空闲状态的起始时间。Specifically, the first device may receive broadcast information, scheduling indication information, and scheduling. At least one of the restriction information determines a start time for evaluating whether the shared channel is in an idle state.

可选的，所述广播信息包括所述共享信道被释放的时间信息；上述步骤101所述第一设备确定评估共享信道是否处于空闲状态的起始时间，具体的实现方法可以是：所述第一设备将所述广播信息中所述共享信道被释放的时间信息指示的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Optionally, the broadcast information includes time information that the shared channel is released. The first device determines that the shared channel is in an idle state. The specific implementation method may be: A device determines a time indicated by the time information in which the shared channel is released in the broadcast information as a start time for evaluating whether the shared channel is in an idle state.

具体来讲，第二设备发送的广播信息中包含的共享信道被释放的时间信息可以是第二设备自身释放共享信道的时间信息，也可以是通信***中非第一设备、第二设备的其他设备释放共享信道的时间信息。第二设备将共享信道被释放的时间信息通过广播信息广播出来，第一设备接收到该广播信息后，就可以将该广播信息中共享信道被释放的时间信息所指示的时间确定为评估共享信道是否处于空闲状态的起始时间。Specifically, the time information of the shared channel that is included in the broadcast information sent by the second device may be time information of the second device itself releasing the shared channel, or may be other than the first device and the second device in the communication system. The device releases the time information of the shared channel. The second device broadcasts the time information that the shared channel is released by using the broadcast information. After receiving the broadcast information, the first device may determine, as the evaluation shared channel, the time indicated by the time information that the shared channel is released in the broadcast information. Whether it is in the idle start time.

可选的，所述调度指示信息包括所述第二设备为所述第一设备分配的发送上行数据的资源调度信息；上述步骤101所述第一设备确定评估共享信道是否处于空闲状态的起始时间，具体的实现方法可以是：所述第一设备根据接收所述上行数据的资源调度指示信息的时间与所述上行数据的调度指示信息所指示的发送对应的上行数据的时间之间的时序关系，确定所述发送对应的上行数据的时间，并将比所述发送对应的上行数据的时间提前所述预设评估时间的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Optionally, the scheduling indication information includes resource scheduling information that is sent by the second device to the first device to send uplink data. In the foregoing step 101, the first device determines whether to determine whether the shared channel is in an idle state. The specific implementation method may be: a timing between the time when the first device receives the resource scheduling indication information of the uplink data and the time of sending the uplink data corresponding to the scheduling indication information of the uplink data. And determining, by the relationship, the time for transmitting the corresponding uplink data, and determining, by the time that the time of transmitting the corresponding uplink data is earlier than the preset evaluation time, a start time for evaluating whether the shared channel is in an idle state.

具体来讲，第二设备可以通过PDCCH或ePDCCH向第一设备指示在共享信道上传输数据使用的频谱资源、传输方式，这是第二设备发送给第一设备的发送上行数据的资源调度信息。根据通信***中上行数据的资源调度信息和该上行数据的调度信息所指示的发送对应的上行数据的时间之间的时序关系，第一设备在接收到该上行数据的资源资源调度信息后隔一段时间(例如，LTE中的4个子帧)就是其使用时频资源发送对应的上行数据的时间。因此第一设备就可以将比发送对应的上行数据的时间提前预设评估时间的时间确定为评估所述共享信道是否处于空闲状态的起始时间。由于第一设备在发送对应的上行数据的时间之前提前评估了共享信道是否处于空闲状态，因此提高了第一设备在发送对应的上行数据的时间占用上共享信道的概率。Specifically, the second device may indicate, by using the PDCCH or the ePDCCH, the spectrum resource and the transmission mode used by the second device to transmit data on the shared channel, where the second device sends the uplink scheduling data to the first device. The first device receives the resource resource scheduling information of the uplink data after receiving the resource resource scheduling information of the uplink data according to the timing relationship between the resource scheduling information of the uplink data in the communication system and the scheduling information of the uplink data. The time (for example, 4 subframes in LTE) is the time at which the time-frequency resource is used to transmit the corresponding uplink data. Therefore, the first device may determine the time when the time for transmitting the corresponding uplink data is advanced by the preset evaluation time as the start time for evaluating whether the shared channel is in an idle state. Since the first device evaluates whether the shared channel is in an idle state before the time for transmitting the corresponding uplink data, the probability that the first device occupies the shared channel when transmitting the corresponding uplink data is improved.

可选的，所述调度指示信息包括所述第二设备发送下行数据的调度信息；上述步骤101所述第一设备确定评估共享信道是否处于空闲状态的起始时间，具体的实现方法可以是：所述第一设备将所述下行数据的调度信息指示的所述共享信道被释放的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Optionally, the scheduling indication information includes a scheduling signal that the second device sends downlink data. The first device determines the start time of the shared channel to be in the idle state. The specific implementation method may be: the first device indicates that the shared channel indicated by the scheduling information of the downlink data is The time of release is determined as the start time to evaluate whether the shared channel is in an idle state.

具体来讲，第二设备向第一设备发送的下行数据中包括了下行数据的调度信息，该调度信息是专发送给第一设备的，而不是上述广播信息可以被多个通信设备接收，该调度信息中也包含共享信道被释放的时间，第一设备获取到该下行数据的调度信息后，就可以将下行数据的调度信息指示的共享信道被释放的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Specifically, the downlink data sent by the second device to the first device includes scheduling information of the downlink data, where the scheduling information is specifically sent to the first device, instead, the broadcast information may be received by multiple communications devices, where The scheduling information also includes the time when the shared channel is released. After the first device obtains the scheduling information of the downlink data, the time that the shared channel indicated by the scheduling information of the downlink data is released may be determined to be an evaluation of whether the shared channel is in the The start time of the idle state.

可选的，所述调度限制信息包括预先配置的所述第二设备占用共享信道的时间范围信息；上述步骤101所述第一设备确定评估共享信道是否处于空闲状态的起始时间，具体的实现方法可以是：所述第一设备将所述调度限制信息中所述第二设备占用共享信道的时间范围信息指示的结束时间确定为评估所述共享信道是否处于空闲状态的起始时间。Optionally, the scheduling restriction information includes a pre-configured time range information of the second device occupying the shared channel, where the first device determines, in step 101, a start time for evaluating whether the shared channel is in an idle state, and the specific implementation is performed. The method may be: the first device determines, in the scheduling restriction information, an end time indicated by the time range information of the second device occupying the shared channel as a start time for evaluating whether the shared channel is in an idle state.

具体来讲，调度限制信息可以是半静态调度信息，通信***中的各设备各自占用共享信道的时间范围是预先分配好的，例如eNodeB向UE发送下行数据只能在预设置的下行子帧的时间范围内，第一设备根据调度限制信息即可获知第二设备占用共享信道的时间范围，就可以将调度限制信息中第二设备占用共享信道的时间范围信息指示的结束时间确定为评估所述共享信道是否处于空闲状态的起始时间。Specifically, the scheduling restriction information may be semi-persistent scheduling information, and the time range in which each device in the communication system occupies the shared channel is pre-allocated. For example, the eNodeB sends the downlink data to the UE only in the preset downlink subframe. In the time range, the first device can learn the time range of the shared channel occupied by the second device according to the scheduling restriction information, and determine the end time indicated by the time range information of the shared channel occupied by the second device in the scheduling restriction information as the evaluation. Whether the shared channel is in the idle state.

可选的，第一设备收到的是上述广播信息、调度指示信息、调度限制信息中任意两项或三项信息时，第一设备可以根据上述三类信息对应的过程分别确定出一个评估共享信道是否处于空闲状态的起始时间，然后第一设备根据传输数据的需求最终确定出一个起始时间。例如，第一设备收到广播信息和包括第二设备为第一设备分配的发送上行数据的资源调度信息的调度指示信息，这时第一设备由于可以获取到发送对应的上行数据的时间，因此第一设备可取用根据调度指示信息确定出来的起始时间；第一设备收到广播信息和调度限制信息，这时由于调度限制信息是专发送给第一设备的，因此第一设备可取用根据调度限制信息确定出来的起始时间。需要说明的是，此处对第一设备收到多种信息确定评估共享信道是否处于空闲状态的起始时间的过程是示例性说明，第一设备还可以根据实际的传输数据的情况和需求以其他规则取用相应的起始时间，对此不做具体限定。Optionally, when the first device receives any two or three pieces of the foregoing broadcast information, scheduling indication information, and scheduling restriction information, the first device may determine an evaluation sharing according to the processes corresponding to the foregoing three types of information. Whether the channel is in the start time of the idle state, and then the first device finally determines a start time according to the demand of the transmitted data. For example, the first device receives the broadcast information and the scheduling indication information of the resource scheduling information that is sent by the second device to the first device, and the first device can obtain the time for sending the corresponding uplink data. The first device may obtain the start time determined according to the scheduling indication information; the first device receives the broadcast information and the scheduling restriction information, and at this time, since the scheduling restriction information is specifically sent to the first device, the first device may use the The start time for which the scheduling limit information is determined. It should be noted that, here, the first device receives multiple information to determine whether the shared channel is in the idle state. The process is exemplified, and the first device may also use the corresponding start time according to other conditions and requirements of the actual data transmission, which is not specifically limited.

可选的，上述步骤101所述第一设备确定评估共享信道是否处于空闲状态的起始时间，具体的实现方法可以是：所述第一设备将与第二设备预先设置的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Optionally, the first device determines, according to the foregoing step 101, a start time for evaluating whether the shared channel is in an idle state, and the specific implementation manner may be: determining, by the first device, a preset time with the second device as an evaluation center. Indicates whether the shared channel is in the idle state.

具体来讲，第一设备和第二设备可以在通信之前预先设置好一个时间，第一设备可以将该设置的时间确定为评估所述共享信道是否处于空闲状态的起始时间。Specifically, the first device and the second device may be preset for a time before the communication, and the first device may determine the set time as a start time for evaluating whether the shared channel is in an idle state.

可选的，所述预设评估时间的时长包括至少一个预设时间段的长度。Optionally, the duration of the preset evaluation time includes a length of at least one preset time period.

具体来讲，预设时间段为第一设备评估一次共享信道是否处于空闲状态所需要的时间，其时长也可以是由通信***中高层预先配置的一个固定时长，也可以是第一设备和第二设备在通信前提前约定的一个固定时长，而预设评估时间的时长包括至少一个所述预设时间段的长度。例如一个预设时间段的长度为20μs或18μs，以下以20μs为例说明。这样预设评估时间的时长可以是一个20μs，也可以是P个20μs，P为预设的大于1的自然数。Specifically, the preset time period is a time required for the first device to evaluate whether the shared channel is in an idle state, and the duration may be a fixed duration that is pre-configured by the upper layer of the communication system, or may be the first device and the first device. The second device has a fixed length of time agreed upon before the communication, and the duration of the preset evaluation time includes the length of at least one of the preset time periods. For example, the length of a preset time period is 20 μs or 18 μs, and the following is an example of 20 μs. Thus, the preset evaluation time may be a time of 20 μs or P 20 μs, and P is a preset natural number greater than 1.

可选的，上述步骤102所述第一设备从所述起始时间开始在预设评估时间内评估所述共享信道是否处于空闲状态，具体实现方法可以是：若所述第一设备在所述预设评估时间内评估所述共享信道的能量值高于预设功率判断门限，则确定所述共享信道不处于空闲状态；若所述第一设备在所述预设评估时间内评估所述共享信道的能量值低于或等于所述预设功率判断门限，则确定所述共享信道为空闲状态。Optionally, the first device, in the foregoing step 102, is configured to determine whether the shared channel is in an idle state in the preset evaluation time, where the first device is in the Determining that the energy value of the shared channel is higher than a preset power determination threshold in a preset evaluation time, determining that the shared channel is not in an idle state; and if the first device evaluates the sharing in the preset evaluation time If the energy value of the channel is lower than or equal to the preset power determination threshold, it is determined that the shared channel is in an idle state.

具体来讲，第一设备在从确定的评估所述共享信道是否处于空闲状态的起始时间开始，在预设评估时间的时长内检测共享信道的状态，若在所述预设评估时间内检测到所述共享信道的能量值低于或等于预设功率判断门限，则确定所述共享信道为空闲状态；若在所述预设评估时间内检测到所述共享信道的能量值高于预设功率判断门限，则第一设备确定所述共享信道不处于空闲状态。共享信道的能量值可以是第一设备在共享信道上测量到的信道质量、干扰、功率等值。Specifically, the first device detects a state of the shared channel within a preset time period of the preset evaluation time from a determined start time of determining whether the shared channel is in an idle state, if the detection is performed within the preset evaluation time If the energy value of the shared channel is lower than or equal to the preset power determination threshold, determining that the shared channel is in an idle state; if the energy value of the shared channel is detected to be higher than a preset in the preset evaluation time The power determining threshold, the first device determines that the shared channel is not in an idle state. The energy value of the shared channel may be the channel quality, interference, power, etc. measured by the first device on the shared channel.

可选的，上述步骤103所述第一设备根据评估所述共享信道是否处于空闲状态的评估结果确定是否在所述共享信道上传输数据，具体的实现方法可以是：所述第一设备在所述预设评估时间结束的时刻评估确定所述共享信道为所述空闲状态，则在所述共享信道上传输数据；或者，所述第一设备在所述预设评估时间结束的时刻评估确定所述共享信道不处于空闲状态，则不在所述共享信到上传输数据。Optionally, the first device in step 103 determines whether to transmit data on the shared channel according to an evaluation result of evaluating whether the shared channel is in an idle state, and the specific implementation manner may be implemented. Therefore, the first device evaluates that the shared channel is in the idle state when the preset evaluation time ends, and then transmits data on the shared channel; or, the first device is in the When the time evaluation of the end of the preset evaluation time determines that the shared channel is not in the idle state, the data is not transmitted on the shared message.

具体来讲，第一设备在预设评估时间结束的时刻确定共享信道为空闲状态，则直接占用共享信道，在共享信到上传输数据即可；而第一设备在预设评估时间结束的时刻确定共享信道不处于空闲状态，则当前不能在共享信到上传输数据。Specifically, the first device determines that the shared channel is in an idle state at the time when the preset evaluation time ends, and directly occupies the shared channel, and the data is transmitted on the shared message; and the first device ends at the preset evaluation time. If it is determined that the shared channel is not in an idle state, data cannot currently be transmitted on the shared message.

第一设备需要继续评估共享信道是否处于空闲状态，从预设评估时间结束的时间开始，在另一个预设评估时间内评估共享信道是否处于空闲状态，所述另一个预设评估时间的时长为Q个预设时间段的长度，Q为第一设备在1到共享信道是否处于空闲状态的最大评估次数中随机选取的自然数，所述共享信道是否处于空闲状态的最大评估次数为预设的值。第一设备这样一直重复评估过程，直到评估出共享信道为空闲状态时才在共享信道上传输数据。The first device needs to continue to evaluate whether the shared channel is in an idle state, and starts from the time when the preset evaluation time ends, and evaluates whether the shared channel is in an idle state in another preset evaluation time, and the duration of the another preset evaluation time is Q is the length of the preset time period, and Q is a natural number randomly selected by the first device from 1 to the maximum evaluation number of whether the shared channel is in an idle state, and the maximum evaluation number of whether the shared channel is in an idle state is a preset value. . The first device thus repeats the evaluation process until data is transmitted on the shared channel until the shared channel is evaluated to be in an idle state.

上述方法实施例中在第一设备传输数据之前，共享信道可以是被第二设备占用，也可以是被其他UE占用，因此第一设备确定评估共享信道是否处于空闲状态的起始时间是上述两种设备最后释放共享信道的时间，例如，如果eNodeB只对一个UE进行调度，那么该UE就将eNodeB释放共享信道的时间作为所述起始时间，如果eNodeB对两个UE进行调度，那么第一个调度的UE是将eNodeB释放共享信道的时间作为所述起始时间，第二个调度的UE就是将第一个UE释放共享信道的时间作为所述起始时间。In the foregoing method embodiment, before the data is transmitted by the first device, the shared channel may be occupied by the second device or may be occupied by other UEs. Therefore, the start time of the first device determining whether the shared channel is in an idle state is the foregoing two. The time when the device finally releases the shared channel. For example, if the eNodeB only schedules one UE, the UE uses the time when the eNodeB releases the shared channel as the start time. If the eNodeB schedules the two UEs, the first The scheduled UEs use the time when the eNodeB releases the shared channel as the start time, and the second scheduled UE is the time when the first UE releases the shared channel as the start time.

图2为本发明传输数据的方法的另一个实施例的流程图，如图2所示，本实施例的方法可以包括：2 is a flowchart of another embodiment of a method for transmitting data according to the present invention. As shown in FIG. 2, the method in this embodiment may include:

步骤201、第二设备确定指示信息，所述指示信息用于指示第一设备在传输数据前对共享信道是否处于空闲状态进行评估的起始时间；Step 201: The second device determines indication information, where the indication information is used to indicate a start time of the first device to evaluate whether the shared channel is in an idle state before transmitting the data.

本实施例与图1所示的方法实施例相对应，是与上述第一设备进行通信的第二设备侧的方法实施例。本实施例中为了提高通信***中的至少一个第一设备根据所述指示信息确定在传输数据之前对共享信道是否处于空闲状态进行评估的起始时间，从该起始时间开始到预设评估时间结束的时刻评估确定所述共享信道是否处于空闲状态。由于第一设备在传输数据的时间之前就开始对共享信道是否处于空闲状态进行了评估，这样第一设备在预设评估时间内检测出共享信道处于空闲状态的可能性就大，而第一设备一旦占用了共享信道就可以在预期时间使用预先分配的资源传输数据。This embodiment corresponds to the method embodiment shown in FIG. 1 and is a method embodiment of the second device side that communicates with the first device. In this embodiment, in order to improve, at least one first device in the communication system determines, according to the indication information, a start time for evaluating whether the shared channel is in an idle state before transmitting data, starting from the start time to a preset evaluation time. The end of the assessment is indeed Whether the shared channel is in an idle state. Since the first device starts to evaluate whether the shared channel is in an idle state before the time of transmitting the data, the first device is likely to detect that the shared channel is in an idle state within a preset evaluation time, and the first device is Once the shared channel is occupied, the data can be transmitted using the pre-allocated resources at the expected time.

步骤202、所述第二设备与所述第一设备在所述共享信道上传输数据，所述传输数据的起始时间在所述第一设备评估所述共享信道为空闲状态之后。Step 202: The second device and the first device transmit data on the shared channel, where a start time of the transmission data is after the first device evaluates that the shared channel is in an idle state.

在第一设备评估出共享信道为空闲状态之后，就可以占用共线信道，然后第二设备和第一设备可以通过该共享信道传输数据。After the first device evaluates that the shared channel is in an idle state, the collinear channel can be occupied, and then the second device and the first device can transmit data through the shared channel.

本实施例，第二设备通过向第一设备发送指示第一设备在传输数据前对共享信道是否处于空闲状态进行评估的起始时间的指示信息，使第一设备根据指示信息确定评估共享信道是否处于空闲状态的起始时间，提高了第一设备在预设评估时间内检测出共享信道处于空闲状态的概率，使第一设备可以有效地占用共享信道并在所述共享信道上传输数据，避免预先分配资源的浪费，提高通信***的传输效率。In this embodiment, the second device, by sending, to the first device, indication information indicating that the first device evaluates whether the shared channel is in an idle state before transmitting the data, and determining, by the first device, whether the shared channel is evaluated according to the indication information The start time of the idle state improves the probability that the first device detects that the shared channel is in an idle state within a preset evaluation time, so that the first device can effectively occupy the shared channel and transmit data on the shared channel, thereby avoiding The waste of resources is allocated in advance, and the transmission efficiency of the communication system is improved.

可选的，上述步骤201第二设备确定指示信息之后，所述方法还包括：所述第二设备向所述至少一个第一设备发送所述指示信息，所述指示信息包括用于指示所述第一设备在传输数据前对所述共享信道是否处于空闲状态进行评估的起始时间的广播信息、调度指示信息、调度限制信息中的至少一项信息。Optionally, after the second device determines the indication information, the method further includes: the second device sending the indication information to the at least one first device, where the indication information includes At least one of broadcast information, scheduling indication information, and scheduling restriction information of a start time at which the first device evaluates whether the shared channel is in an idle state before transmitting data.

可选的，上述步骤201第二设备确定指示信息之前，所述方法还包括：所述第二设备预先设置所述指示信息所指示的所述第一设备对所述共享信道是否处于空闲状态进行评估的起始时间。Optionally, before the second device determines the indication information, the method further includes: the second device presetting, by the first device, the first device, whether the shared channel is in an idle state. The start time of the assessment.

所述广播信息、所述调度指示信息、所述调度限制信息中包含的信息可以参考图1所示的方法实施例，此处不再赘述。For the information included in the broadcast information, the scheduling indication information, and the scheduling restriction information, reference may be made to the method embodiment shown in FIG. 1 , and details are not described herein again.

下面采用几个具体的实施例，对图1或图2所示方法实施例的技术方案进行详细说明。The technical solutions of the method embodiment shown in FIG. 1 or FIG. 2 are described in detail below by using several specific embodiments.

图3为第一设备和第二设备传输数据的一个时序示意图。假定预设评估时间包括一个预设时间段的长度，所述预设时间段的长度为20μs。如图3所示，第二设备eNodeB发送广播信息，第一设备UE通过该广播消息可以确定 eNodeB将占用共享信道5个子帧，并在子帧n-1结束时刻的前20μs的时刻释放共享信道。确定该时间信息后，第一设备UE即可从子帧n-1结束时刻的前20μs开始检测共享信道的能量值评估共享信道的空闲状态。这样，经过20μs的评估后共享信道空闲，UE就可以在子帧n的开始时刻占用共享信道并传输数据。FIG. 3 is a timing diagram of data transmission by the first device and the second device. It is assumed that the preset evaluation time includes the length of one preset time period, and the length of the preset time period is 20 μs. As shown in FIG. 3, the second device eNodeB sends broadcast information, and the first device UE can determine by using the broadcast message. The eNodeB will occupy 5 subframes of the shared channel and release the shared channel at the first 20 μs of the end of the subframe n-1. After determining the time information, the first device UE can detect the idle state of the shared channel by detecting the energy value of the shared channel from the first 20 μs of the end time of the subframe n-1. Thus, after 20 μs of evaluation, the shared channel is idle, and the UE can occupy the shared channel and transmit data at the beginning of the subframe n.

图4为第一设备和第二设备传输数据的另一个时序示意图，如图4所示，第二设备eNodeB在子帧n-4通过PDCCH或ePDCCH向第一设备UE发送资源调度信息，指示UE在子帧n发送上行数据，通过该资源调度信息，UE根据接收资源调度信息的时间(子帧n-4)与发送对应的上行数据的时间(子帧n)之间的时序关系确定从子帧n-1结束时刻的前20μs的时刻为共享信道被释放的时间并从该时刻开始检测共享信道的能量值评估共享信道的空闲状态。这样，经过20μs的评估后共享信道空闲，UE就可以在子帧n的开始时刻按照预期在子帧n时占用共享信道并传输数据。4 is another timing diagram of the first device and the second device transmitting data. As shown in FIG. 4, the second device eNodeB sends resource scheduling information to the first device UE through the PDCCH or the ePDCCH in the subframe n-4, indicating the UE. Transmitting uplink data in the subframe n, by using the resource scheduling information, the UE determines the slave according to the time relationship between the time (subframe n-4) of receiving the resource scheduling information and the time (subframe n) of transmitting the corresponding uplink data. The first 20 μs of the end time of the frame n-1 is the time at which the shared channel is released and the energy value of the shared channel is detected from the time to evaluate the idle state of the shared channel. Thus, after the 20 μs evaluation, the shared channel is idle, and the UE can occupy the shared channel and transmit data at the start time of the subframe n as expected in the subframe n.

图5为第一设备和第二设备传输数据的第三个时序示意图，如图5所示，第二设备eNodeB发送广播信息，第一个第一设备UE1和第二个第一设备UE2可以根据广播信息确定共享信道被释放的时间信息。UE1可以确定共享信道被第二设备释放的时间为子帧n-1结束时刻的前20μs的时刻。UE2可以确定共享信道被UE1释放的时间为子帧n+1结束时刻的前20μs的时刻。确定上述时间信息后，UE1即可从子帧n-1结束时刻的前20μs开始检测共享信道的能量值评估共享信道的空闲状态。这样，经过20μs的评估后共享信道空闲，UE1就可以在子帧n的开始时刻占用共享信道并传输数据；而UE2即可从子帧n+1结束时刻的前20μs开始检测共享信道的能量值评估共享信道的空闲状态。这样，经过20μs的评估后共享信道空闲，UE2就可以在子帧n+2的开始时刻占用共享信道并传输数据。FIG. 5 is a third timing diagram of data transmission by the first device and the second device. As shown in FIG. 5, the second device eNodeB sends broadcast information, and the first first device UE1 and the second first device UE2 may be configured according to The broadcast information determines time information at which the shared channel is released. The UE 1 may determine that the time when the shared channel is released by the second device is the time of the first 20 μs of the end time of the subframe n-1. UE2 may determine that the time when the shared channel is released by UE1 is the time of the first 20 μs of the end time of subframe n+1. After determining the time information, the UE1 can detect the idle state of the shared channel by detecting the energy value of the shared channel from the first 20 μs of the end time of the subframe n-1. In this way, after the 20μs evaluation, the shared channel is idle, UE1 can occupy the shared channel and transmit data at the beginning of the subframe n; and UE2 can detect the energy value of the shared channel from the first 20μs of the end of the subframe n+1. Evaluate the idle state of the shared channel. Thus, after the 20 μs evaluation, the shared channel is idle, and UE2 can occupy the shared channel and transmit data at the beginning of the subframe n+2.

可选的，eNodeB和UE之间可以预先设置时间关系，例如，将每个子帧的前20μs作为预设评估时间，或者将每个子帧的后20μs作为预设评估时间，第一设备在该预设评估时间的起始时刻开始评估共享信道的空闲状态。Optionally, a time relationship may be preset between the eNodeB and the UE, for example, the first 20 μs of each subframe is used as a preset evaluation time, or the last 20 μs of each subframe is used as a preset evaluation time, where the first device is in the pre- Let the start time of the evaluation time begin to evaluate the idle state of the shared channel.

图6为本发明通信***的一个实施例的结构示意图，如图6所示，宏基站(Macro eNodeB)和微基站(Pico eNodeB)之间通过共享信道的资源传递回传(Backhaul)数据，同时宏基站与UE、微基站与UE分别也通过共享信道传输数据。宏基站、微基站、UE中的任意一者在通过共享信道传输数据前需要评估共享信道的空闲状态，其中宏基站和微基站可以交替充当第一设备和第二设备。图7为第一设备和第二设备传输数据的第四个时序示意图，如图7所示，本实施例中宏基站作为第二设备先占用共享信道从子帧n-4到子帧n-1结束时刻前20μs，宏基站向微基站发送广播信息，包括共享信道被释放的时间信息，此时微基站作为第一设备，微基站根据广播信息确定评估共享信道是否处于空闲状态的起始时间为子帧n-1结束时刻前20μs的时刻；微基站从该起始时间(即子帧n-1结束时刻前20μs的时刻)开始在20μs内评估出共享信道的空闲状态。如果评估结果是共享信道空闲，则从子帧n到子帧n+1占用共享信道；微基站又作为第二设备向宏基站发送广播信息，此时宏基站作为第一设备，宏基站根据广播信息确定评估共享信道是否处于空闲状态的起始时间为子帧n+2的开始时刻；宏基站从起始时间(即子帧n+2的开始时刻)开始在20μs内评估出共享信道的空闲状态。如果评估结果是共享信道空闲，从子帧n+2开始后的20μs处到子帧n+3结束时刻前20μs占用共享信道。以此类推，宏基站和微基站通过交替充当第一设备和第二设备，实现提高第一设备在确定的时间和频率资源上检测到共享信道的空闲状态的概率，使得第一设备和第二设备交替占用共享信道并在共享信道上通信，避免预先分配资源的浪费，提高通信***的传输效率。FIG. 6 is a schematic structural diagram of an embodiment of a communication system according to the present invention. As shown in FIG. 6, a macro base station (Macro eNodeB) and a micro base station (Pico eNodeB) transmit backhaul data through resources of a shared channel, and simultaneously The macro base station and the UE, the micro base station, and the UE respectively share the letter Channel transfer data. Any one of the macro base station, the micro base station, and the UE needs to evaluate the idle state of the shared channel before transmitting the data through the shared channel, wherein the macro base station and the micro base station can alternately serve as the first device and the second device. FIG. 7 is a fourth timing diagram of data transmission by the first device and the second device. As shown in FIG. 7, in this embodiment, the macro base station as the second device first occupies the shared channel from the subframe n-4 to the subframe n- The macro base station sends the broadcast information to the micro base station, including the time information that the shared channel is released. At this time, the micro base station serves as the first device, and the micro base station determines, according to the broadcast information, the start time for evaluating whether the shared channel is in an idle state. It is the time 20 μs before the end of the subframe n-1; the micro base station evaluates the idle state of the shared channel within 20 μs from the start time (that is, the time 20 μs before the end of the subframe n-1). If the evaluation result is that the shared channel is idle, the shared channel is occupied from the subframe n to the subframe n+1; the micro base station transmits the broadcast information to the macro base station as the second device, and the macro base station serves as the first device, and the macro base station broadcasts according to the broadcast. The information determines that the start time of evaluating whether the shared channel is in an idle state is the start time of the subframe n+2; the macro base station evaluates the idle of the shared channel within 20 μs from the start time (ie, the start time of the subframe n+2) status. If the evaluation result is that the shared channel is idle, the shared channel is occupied 20 μs from the start of the subframe n+2 to the end of the subframe n+3. By analogy, the macro base station and the micro base station realize the probability of detecting the idle state of the shared channel on the determined time and frequency resources by alternately acting as the first device and the second device, so that the first device and the second device The device alternately occupies the shared channel and communicates on the shared channel, avoiding waste of pre-allocated resources and improving the transmission efficiency of the communication system.
