本发明实施例提供的技术方案，由基站为Remote UE配置用于UE-to-network中继的D2D link发送资源池(即Remote UE D2D link Tx资源池)。由于是基站配置的Remote UE的D2D link发送资源池，因此也就获知了Remote UE的D2D link发送资源池的时域资源的信息。那么，基站就可以根据Remote UE的D2D link发送资源池的时域资源的信息，为Relay UE调度蜂窝上行传输资源，从而降低甚至避免Relay UE的蜂窝上行传输与Remote UE D2D link Tx资源之间的资源冲突；基站也可以根据Remote UE中的D2D link发送资源池的时域资源的信息，为Relay UE调度用于Relay UE D2D link Tx资源，或者为Relay UE配置用于Relay UE D2D link Tx资源池，从而降低甚至避免Relay UE D2D link Tx资源与Rx资源之间的冲突。可见，本发明实施例提供的Remote UE D2D link Tx资源池的配置方案，能够有效减少UE-to-network中继的资源冲突，提高UE-to-network中继的效率和可靠性。In the technical solution provided by the embodiment of the present invention, the base station configures a D2D link transmission resource pool (ie, a Remote UE D2D link Tx resource pool) for the UE-to-network relay for the Remote UE.

detailed description

在对本发明实施例的方案进行描述之前，首先对本发明实施例中涉及到的资源以及资源池的概念进行说明。Before describing the solution of the embodiment of the present invention, the concept of the resource and resource pool involved in the embodiment of the present invention is first described.

Remote UE的D2D link发送资源池(或资源)，又称Remote UE D2D link Tx资源池(或资源)，即Remote UE用于UE-to-network中继的D2D link Tx的资源池(或资源)，也是Relay UE用于UE-to-network中继的D2D link Rx(接收)的资源池(或资源)；The remote UE's D2D link sends a resource pool (or resource), also known as the Remote UE D2D link Tx resource pool (or Resource), that is, the resource pool (or resource) of the D2D link Tx used by the Remote UE for the UE-to-network relay, and also the resource pool of the D2D link Rx (receive) used by the Relay UE for the UE-to-network relay ( Or resource);

Relay UE的D2D link发送资源池(或资源)，又称Relay UE D2D link Tx资源池(或资源)，即Relay UE用于UE-to-network中继的D2D link Tx的资源池(或资源)，也是Remote UE用于UE-to-network中继的D2D link Rx的资源池(或资源)。The D2D link of the Relay UE sends a resource pool (or resource), also known as the Relay UE D2D link Tx resource pool (or resource), that is, the resource pool (or resource) of the D2D link Tx used by the Relay UE for the UE-to-network relay. It is also the resource pool (or resource) of the D2D link Rx used by the Remote UE for the UE-to-network trunk.

预配置的覆盖外UE的资源池，包括覆盖外UE的D2D发现资源池(又分为接收资源池和发送资源池)，和覆盖外UE的D2D通信资源池(又分为接收资源池和发送资源池)。The pre-configured resource pool of the out-of-band UE, including the D2D discovery resource pool of the out-of-band UE (also divided into the receiving resource pool and the sending resource pool), and the D2D communication resource pool covering the outer UE (also divided into the receiving resource pool and sending Resource pool).

下面将结合附图，对本发明实施例提供的技术方案进行详细说明。The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

本发明实施例提供了一种资源协调的指示方法，该方法在基站侧的实现方式如图2所示，包括如下操作：An embodiment of the present invention provides a method for indicating resource coordination. The implementation manner of the method on the base station side is as shown in FIG. 2, and includes the following operations:

步骤100、为至少一个Remote UE配置设备到设备链路资源池，该设备到设备链路资源池的配置至少包括时域资源的信息，该设备到设备链路资源池中的资源用于UE-to-network的中继传输。Step 100: Configure a device-to-device link resource pool for at least one Remote UE, where the configuration of the device-to-device link resource pool includes at least information of a time domain resource, and the resource in the device-to-device link resource pool is used for the UE- Relay transmission to-network.

即，至少为Remote UE配置设备到设备链路资源池的时域资源。That is, at least the time domain resource of the device to device link resource pool is configured for the Remote UE.

步骤110、通过上述Remote UE对应的Relay UE，向上述Remote UE通知为其配置的设备到设备链路资源池。Step 110: Notify, by the Relay UE corresponding to the Remote UE, the Remote UE to the device-to-device link resource pool configured for the Remote UE.

其中，Relay UE是指为Remote UE提供UE-to-network中继的UE。The Relay UE refers to a UE that provides a UE-to-network relay for the Remote UE.

其中，步骤100的实现方式有多种，例如，基站根据预配置的覆盖外UE的资源池(具体是D2D资源池，包括D2D通信资源池和/或D2D发现资源池)的配置信息，为至少一个Remote UE配置设备到设备链路资源池。具体的，是根据预配置的配置信息选择至少一个覆盖外D2D link发送资源池确定为Remote UE的D2D link发送资源池。相应的，在配置Remote UE的D2D link发送资源池之前，基站需要获知覆盖外UE的资源池的配置信息。具体的获知方式有多种，例如通过预定义的方式获知，也可以通过接收Relay UE上报的预配置的覆盖外UE的资源池的配置信息的方式获知。The implementation of the step 100 is different. For example, the base station is configured according to the configuration information of the pre-configured resource pool of the external UE (specifically, the D2D resource pool, including the D2D communication resource pool and/or the D2D discovery resource pool). A Remote UE configures the device to the device link resource pool. Specifically, the D2D link sending resource pool determined to be the Remote UE by the at least one outbound D2D link sending resource pool is selected according to the preconfigured configuration information. Correspondingly, before configuring the D2D link transmission resource pool of the Remote UE, the base station needs to know the configuration information of the resource pool of the external UE. The specific methods for obtaining the information are obtained in a predefined manner, for example, by receiving the configuration information of the pre-configured resource pool of the out-of-band UE reported by the Relay UE.

其中，步骤110的实现方式有多种，下面列举其中几种。There are various implementations of step 110, and several of them are listed below.

步骤110的实现方式一：The implementation of step 110 is as follows:

向上述Relay UE发送上述设备到设备链路资源池的标识信息，以向Remote UE通知为其配置的设备到设备链路资源池。Sending the identifier information of the device to the device link resource pool to the Relay UE to notify the Remote UE of the device-to-device link resource pool configured for the same.

以D2D通信(communication)为例，其中物理直通控制信道(Physical Sidelink Control Channel，PSCCH)资源池与物理直通共享信道(Physical Sidelink Shared Channel，PSSCH)资源池之间有一一对应的关联关系，因此通过指示PSCCH或者PSSCH资源池的标识信息两者之一即可。Taking D2D communication as an example, there is a corresponding relationship between a physical side-link control channel (PSCCH) resource pool and a physical side-link shared channel (PSSCH) resource pool, so It may be one of indicating the identification information of the PSCCH or the PSSCH resource pool.

假设步骤100中，基站从预配置的覆盖外UE的D2D资源池中选择至少一个资源池作为Remote UE的设备到设备链路资源池，那么步骤110可以采用上述实现方式一。Assume that in step 100, the base station selects at least one resource pool from the D2D resource pool of the pre-configured out-of-band UE as the device-to-device link resource pool of the Remote UE. Step 110 may adopt the foregoing implementation manner 1.

假设步骤100中，基站从操作维护中心(Operation and Maintenance Center，OMC)配置的覆盖外的D2D资源池中选择至少一个资源池作为Remote UE的设备到设备链路资源池，那么步骤110可以采用上述实现方式一。但这种情况下，基站发送的设备到设备链路资源池的标识信息是OMC配置的标识信息，基站需要预先将OMC配置的覆盖外的D2D资源池的配置信息发送给Relay UE。Assume that in step 100, the base station selects at least one resource pool from the out-of-coverage D2D resource pool configured by the Operation and Maintenance Center (OMC) as the device-to-device link resource pool of the Remote UE, and then step 110 may be adopted. Implementation one. In this case, the identifier information of the device-to-device link resource pool sent by the base station is the identifier information of the OMC configuration, and the base station needs to send the configuration information of the D2D resource pool configured by the OMC to the Relay UE in advance.

假设步骤100中，基站独立为Remote UE配置设备到设备链路资源池，且为该设备到设备链路资源池分配了标识信息，并将设备到设备链路资源池的配置信息(包括标识信息)发送给了Relay UE。那么，步骤110也可以采用上述实现方式一。It is assumed that, in step 100, the base station independently configures a device-to-device link resource pool for the Remote UE, and assigns identification information to the device-to-device link resource pool, and configures information (including identification information) from the device to the device link resource pool. ) was sent to the Relay UE. Then, step 110 can also adopt the above implementation manner 1.

步骤110的实现方式二：向上述Relay UE发送上述设备到设备链路资源池的完整配置信息，以向上述Remote UE通知为其配置的设备到设备链路资源池。The implementation of step 110 is as follows: The complete configuration information of the device-to-device link resource pool is sent to the relay UE to notify the remote UE of the device-to-device link resource pool configured for the remote UE.

相应的，步骤100中，基站为Remote UE配置了完整的设备到设备链路资源池，即配置了该资源池的时域资源、频域资源、循环前缀(Cyclic Prefix，CP)等等信息。可选的，完整配置信息中还包括资源池的标识信息。Correspondingly, in step 100, the base station configures a complete device-to-device link resource pool for the Remote UE, that is, the time domain resource, the frequency domain resource, the Cyclic Prefix (CP), and the like of the resource pool are configured. Optionally, the complete configuration information also includes identifier information of the resource pool.

步骤110的实现方式三：向上述Remote UE发送上述设备到设备链路资源池的部分配置信息，以向上述Remote UE通知为其配置的设备到设备链路资源池。其中，部分配置信息是上述设备到设备链路资源池的预定义配置信息之外的配置信息。The third implementation of the step 110 is to send the partial configuration information of the device to the device link resource pool to the remote UE to notify the remote UE of the device-to-device link resource pool configured for the remote UE. The part of the configuration information is configuration information other than the predefined configuration information of the device to the device link resource pool.

相应的，Remote UE的设备到设备链路资源池的一部分配置信息是预定义的，另外一部分配置信息是由基站配置的。其中，至少时域资源的配置信息是由基站配置的。例如，CP是预定义的，时频资源的配置信息是基站配置的。Correspondingly, part of the configuration information of the device-to-device link resource pool of the Remote UE is predefined, and another part of the configuration information is configured by the base station. The configuration information of at least the time domain resource is configured by the base station. For example, the CP is predefined, and the configuration information of the time-frequency resource is configured by the base station.

本发明实施例提供了一种资源协调的指示方法，该方法在Relay UE侧的实现方式如图3所示，具体包括如下操作： An embodiment of the present invention provides a method for indicating resource coordination. The implementation manner of the method on the Relay UE side is as shown in FIG. 3, and specifically includes the following operations:

步骤200、接收基站为Remote UE配置的设备到设备链路资源池的通知，该设备到设备链路资源池中的资源用于Remote UE的UE-to-network中继的传输。Step 200: Receive a notification that the base station is a device-to-device link resource pool configured by the Remote UE, and the resource in the device-to-device link resource pool is used for transmission of the UE-to-network relay of the Remote UE.

步骤210、将上述通知转发给上述Remote UE。Step 210: Forward the foregoing notification to the Remote UE.

本发明实施例提供的技术方案，由基站为Remote UE配置用于UE-to-network中继的D2D link发送资源池(即Remote UE D2D link Tx资源池)，并通过Relay UE通知Remote UE为其配置的D2D link发送资源池。由于是基站配置的Remote UE的D2D link发送资源池，因此也就获知了Remote UE的D2D link发送资源池的时域资源的信息。那么，基站就可以根据Remote UE的D2D link发送资源池的时域资源的信息，为Relay UE调度蜂窝上行传输资源，从而降低甚至避免Relay UE的蜂窝上行传输与Remote UE D2D link Tx资源之间的资源冲突；基站也可以根据Remote UE中的D2D link发送资源池的时域资源的信息，为Relay UE调度用于Relay UE D2D link Tx资源，或者为Relay UE配置用于Relay UE D2D link Tx资源池，从而降低甚至避免Relay UE D2D link Tx资源与Rx资源之间的冲突。可见，本发明实施例提供的Remote UE D2D link Tx资源池的配置方案，能够有效减少UE-to-network中继的资源冲突，提高UE-to-network中继的效率和可靠性。According to the technical solution provided by the embodiment of the present invention, the base station configures a D2D link transmission resource pool (ie, a Remote UE D2D link Tx resource pool) for the UE-to-network relay for the Remote UE, and notifies the Remote UE of the UE by the Relay UE. The configured D2D link sends the resource pool. Since the D2D link transmission resource pool of the Remote UE configured by the base station is obtained, the information of the time domain resource of the D2D link transmission resource pool of the Remote UE is also known. Then, the base station can send the time-domain resource information of the resource pool according to the D2D link of the Remote UE, and schedule the cellular uplink transmission resource for the Relay UE, thereby reducing or even avoiding the between the cellular uplink transmission of the Relay UE and the Remote UE D2D link Tx resource. Resource conflicts; the base station may also send the time domain resource information of the resource pool according to the D2D link in the Remote UE, and schedule the Relay UE for the Relay UE D2D link Tx resource, or configure the Relay UE for the Relay UE D2D link Tx resource pool. , thereby reducing or even avoiding conflicts between Relay UE D2D link Tx resources and Rx resources. It can be seen that the configuration scheme of the Remote UE D2D link Tx resource pool provided by the embodiment of the present invention can effectively reduce resource conflicts of the UE-to-network relay and improve the efficiency and reliability of the UE-to-network relay.

本发明实施例中，步骤200的实现方式有多种，下面列举其中几种。In the embodiment of the present invention, the implementation of step 200 is various, and several of them are listed below.

步骤200的实现方式一：接收基站为Remote UE配置的设备到设备链路资源池的标识信息。The implementation of step 200 is as follows: receiving the identification information of the device-to-device link resource pool configured by the base station for the Remote UE.

该实现方式对应基站侧步骤110的实现方式一。This implementation manner corresponds to the implementation manner 1 of the base station side step 110.

步骤200的实现方式二：接收基站为Remote UE配置的设备到设备链路资源池的完整配置信息。The implementation of step 200 is as follows: receiving complete configuration information of the device-to-device link resource pool configured by the base station for the Remote UE.

该实现方式对应基站侧步骤110的实现方式二。This implementation manner corresponds to the implementation manner 2 of the base station side step 110.

步骤200的实现方式三：接收基站为Remote UE配置的设备到设备链路资源池的部分配置信息，该部分配置信息是上述设备到设备链路资源池的预定义配置信息之外的配置信息。The implementation of the step 200 is as follows: receiving part of the configuration information of the device-to-device link resource pool configured by the base station for the remote UE, where the part configuration information is configuration information other than the predefined configuration information of the device-to-device link resource pool.

该实现方式对应基站侧步骤110的实现方式三。This implementation manner corresponds to the third implementation manner of the base station side step 110.

基于上述任意方法实施例，步骤210中，Relay UE既可以直接将接收到的通知转发给Remote UE，也可以将上述通知中的信息修改后转发给Remote UE。Based on any of the foregoing method embodiments, in step 210, the Relay UE may directly forward the received notification to the Remote UE, or may modify the information in the notification to be forwarded to the Remote UE.

对于步骤200的实现方式一，如果接收到的标识信息是Remote UE可识别的资源池的标识信息，则可以直接将上述通知转发给Remote UE；如果接收到的标识信息不是Remote UE可识别的资源池的标识信息，则Relay UE需要将接收到的标识信息修改为Remot UE能够识别的标识信息，然后将修改后的标识信息转发给Remote UE。例如，Relay UE接收到的标识信息是OMC配置的标识信息，或者基站独立为Remote UE的设备到设备链路资源池配置的标识信息，那么，Relay UE就需要进行标识信息的转换。 For the first implementation of the step 200, if the received identification information is the identification information of the resource pool that the remote UE can identify, the notification may be directly forwarded to the Remote UE; if the received identification information is not a resource identifiable by the Remote UE. The identification information of the pool, the Relay UE needs to modify the received identification information to the identification information that the Remot UE can identify, and then forward the modified identification information to the Remote UE. For example, if the identifier information received by the Relay UE is the identifier information of the OMC configuration, or the base station is independently configured as the identifier information of the device-to-device link resource pool of the Remote UE, the Relay UE needs to perform the conversion of the identifier information.

对于步骤200的第二种实现方式，Relay UE可以直接将接收到的完整配置信息转发给Remote UE。Relay UE也可以查找预配置的覆盖外UE的D2D资源池的配置信息，如果有与接收到的完整配置信息相同的D2D资源池，将查找到的该D2D资源池的标识信息转发给Remote UE。For the second implementation of step 200, the Relay UE may directly forward the received complete configuration information to the Remote UE. The relay UE may also search for the configuration information of the D2D resource pool of the pre-configured out-of-band UE. If there is a D2D resource pool that is the same as the received complete configuration information, the identifier information of the D2D resource pool that is found is forwarded to the Remote UE.

对于步骤200的第三种实现方式，Relay UE可以直接将接收到的部分配置信息转发给Remote UE。Relay UE也可以查找预配置的覆盖外UE的D2D资源池的配置信息，如果有与接收到的部分配置信息相同的D2D资源池，将查找到的该D2D资源池的标识信息转发给Remote UE。For the third implementation of step 200, the Relay UE may directly forward the received partial configuration information to the Remote UE. The relay UE may also search for the configuration information of the D2D resource pool of the pre-configured out-of-band UE. If there is a D2D resource pool that is the same as the received partial configuration information, the identifier information of the D2D resource pool that is found is forwarded to the Remote UE.

基于上述任意方法实施例，可选的，步骤210中，承载上述通知的方式有多种，下面列举其中几种。Based on any of the foregoing method embodiments, optionally, in step 210, there are multiple ways to carry the notification, and several of them are listed below.

承载上述通知的实现方式一：通过同步信道将上述通知转发给Remote UE。The implementation manner of carrying the foregoing notification 1: forwarding the foregoing notification to the Remote UE through the synchronization channel.

该实现方式一具体又分为如下三种实现方式：The implementation manner is specifically divided into the following three implementation manners:

实现方式一A：将上述通知携带在已有的同步信道中转发给Remote UE。Embodiment 1 A: The foregoing notification is carried in an existing synchronization channel and forwarded to the Remote UE.

其中，已有的同步信道具体是指目前的通信标准中定义的同步信道。The existing synchronization channel specifically refers to a synchronization channel defined in the current communication standard.

例如，将上述通知携带在物理直通广播信道(Physical Sidelink Broadcast Channel，PSBCH)中转发给Remote UE。现有通信标准中定义的PSBCH中包含20bits的保留比特，具体可以通过该保留比特携带上述通知。这种方法尤其适用于传输标识信息，也可以传输部分配置信息。For example, the notification is carried in a Physical Sidelink Broadcast Channel (PSBCH) and forwarded to the Remote UE. The PSBCH defined in the existing communication standard includes 20 bits of reserved bits, and the above notification can be carried by the reserved bits. This method is especially suitable for transmitting identification information and for transmitting partial configuration information.

实现方式一B：将上述通知携带在中继用户设备专用的同步信道中转发给Remote UE。Embodiment 1 B: The foregoing notification is carried in a synchronization channel dedicated to the relay user equipment and forwarded to the Remote UE.

其中，中继用户设备专用的同步信道与已有的同步信道在时域资源上不重叠。The synchronization channel dedicated to the relay user equipment does not overlap with the existing synchronization channel on the time domain resource.

应当指出的是，中继用户设备专用的同步信道与已有的同步信道也可以在频域资源上不重叠。It should be noted that the synchronization channel dedicated to the relay user equipment and the existing synchronization channel may also not overlap on the frequency domain resources.

例如，通过定义新的专用于Relay UE发送的边带链路同步信号(Sidelilnk Synchronization Signal，SL-SS)/PSBCH的资源池，使得Rel-12D2D UE同步资源池在时域或者频域上与专用于Relay UE的同步资源池不重叠，从而降低对Rel-12D2D UE发送的SL-SS/PSBCH的干扰，一种可选的方式可以是配置与Rel-12同步资源池有着不同的子帧偏移值的方式。For example, by defining a new resource pool dedicated to the Sidelink Synchronization Signal (SL-SS)/PSBCH transmitted by the Relay UE, the Rel-12D2D UE synchronization resource pool is dedicated in the time domain or the frequency domain. The synchronization resource pools of the Relay UE do not overlap, thereby reducing the interference of the SL-SS/PSBCH sent by the Rel-12D2D UE. An optional manner may be that the configuration has different subframe offsets from the Rel-12 synchronization resource pool. The way the value is.

实现方式一C：在同步信道中指示携带上述通知的信道资源，并在上述同步信道指示的信道资源中将上述通知转发给Remote UE。Embodiment 1 C: indicating a channel resource carrying the foregoing notification in the synchronization channel, and forwarding the notification to the Remote UE in the channel resource indicated by the synchronization channel.

该实现方式中，同步信道可以是已有的同步信道，也可以是中继用户设备专用的同步信道。In this implementation manner, the synchronization channel may be an existing synchronization channel, or may be a synchronization channel dedicated to the relay user equipment.

例如，在现有标准中定义的PSBCH或者新定义的专用于Relay UE发送的SL-SS/PSBCH中携带传输Remote UE D2D link Tx资源池配置信息的资源指示信息，以 D2D communication为例，其中PSBCH中包含用于传输Remote UE D2D link Tx资源池配置信息的PSCCH的资源指示信息(例如：信道编号，或者具体的物理资源块(Physical Resource Block，PRB)对(pair)起始位置的指示)，并且Relay UE在当前PSBCH传输子帧之后的最近的PSCCH和PSSCH资源池中传输相应的Remote UE D2D link Tx资源池配置信息(即转发上述通知)。Remote UE可以根据检测到的PSBCH中的指示，在对应的PSCCH资源检测PSCCH，并根据PSCCH的指示获得相应的PSSCH中携带的Remote UE D2D link Tx资源池配置信息。For example, the PSBCH defined in the existing standard or the newly defined SL-SS/PSBCH dedicated to the Relay UE transmission carries the resource indication information for transmitting the Remote UE D2D link Tx resource pool configuration information, The D2D communication is used as an example, where the PSBCH includes resource indication information (for example, a channel number, or a specific physical resource block (PRB) pair) for transmitting a PSCCH of the Remote UE D2D link Tx resource pool configuration information. An indication of the starting position), and the Relay UE transmits the corresponding Remote UE D2D link Tx resource pool configuration information (ie, forwards the above notification) in the nearest PSCCH and PSSCH resource pools after the current PSBCH transmission subframe. The remote UE may detect the PSCCH in the corresponding PSCCH resource according to the indication in the detected PSBCH, and obtain the Remote UE D2D link Tx resource pool configuration information carried in the corresponding PSSCH according to the indication of the PSCCH.

当然，用于传输Remote UE D2D link Tx资源池配置信息的PSCCH的资源指示信息也可以指示PSDCH的资源。Of course, the resource indication information of the PSCCH used for transmitting the Remote UE D2D link Tx resource pool configuration information may also indicate the resources of the PSDCH.

其中，如果通过PSBCH中携带PSCCH的资源指示的方法，如果每个PSBCH都包含相应的指示，那么相当于每40ms都需要调度一次用于传输Remote UE D2D link Tx资源池配置信息的PSCCH和PSSCH，这样会限制Relay UE进行其它的PSCCH/PSSCH/蜂窝(Cellular)上行(Uplink，UL)的传输，因此一种可选的方法，是仅在PSBCH传输周期(40ms)的整数倍上的PSBCH中携带用于指示Remote UE D2D link Tx资源池配置信息的PSCCH的资源指示信息。If the PSBCH carries the resource indication method in the PSBCH, if each PSBCH includes a corresponding indication, it is equivalent to scheduling the PSCCH and the PSSCH for transmitting the Remote UE D2D link Tx resource pool configuration information every 40 ms. This will restrict the Relay UE from performing other PSCCH/PSSCH/Cellular uplink (UL) transmissions. Therefore, an optional method is to carry only in the PSBCH on an integer multiple of the PSBCH transmission period (40ms). Resource indication information of the PSCCH used to indicate the Remote UE D2D link Tx resource pool configuration information.

其中，如果Remote UE每次都进行PSCCH和PSSCH的检测，从而获取Remote UE D2D link Tx资源池配置信息会增加UE的检测复杂度，一种可选的方式是通过在PSBCH中增加用于指示Remote UE D2D link Tx资源池配置信息更新的信息域，其可以为1bit，从而Remote UE在PSBCH中检测到该信息域指示配置信息更新，则进行相应的PSCCH和PSSCH的检测。If the Remote UE performs the detection of the PSCCH and the PSSCH every time, the configuration of the Remote UE D2D link Tx resource pool configuration information increases the detection complexity of the UE. An optional manner is to increase the indication in the PSBCH to indicate the remote. The information field updated by the UE D2D link Tx resource pool configuration information may be 1 bit, so that the Remote UE detects that the information field indicates the configuration information update in the PSBCH, and then performs detection of the corresponding PSCCH and PSSCH.

承载上述通知的实现方式二：通过中继发现(Relay Dicovery)过程将上述通知转发给Remote UE。Implementation 2 of carrying the above notification: forwarding the foregoing notification to the Remote UE by a Relay Discovery process.

该实现方式二又可以分为以下两种实现方式：The implementation manner 2 can be further divided into the following two implementation manners:

实现方式二A：将上述通知携带在中继发现(Relay Discovery)消息中转发给Remote UE。Embodiment 2A: The foregoing notification is carried in a Relay Discovery message and forwarded to the Remote UE.

具体可以是在mode A的Relay UE的通知(announcement)消息中携带上述通知，或者在mode B的响应(Response)消息中携带上述通知。Specifically, the notification may be carried in the announcement message of the relay UE of the mode A, or may be carried in the response message of the mode B.

如果Relay discovery的过程沿用D2D discovery的信道，那么由于D2D discovery有比较高的检测成功概率，因此Relay UE通过PSDCH中发送的announcement/response消息中携带相应的Remote UE D2D link Tx资源池的配置信息。If the process of the relay discovery follows the channel of the D2D discovery, the D2D discovery has a relatively high probability of detection success, so the relay UE carries the configuration information of the corresponding Remote UE D2D link Tx resource pool through the announcement/response message sent in the PSDCH.

如果Relay discovery过程采用的是D2D communication的过程，同样Relay UE也可以通过D2D communication的信道(PSCCH和PSSCH)发送的announcement/response消息中携带相应的Remote UE D2D link Tx资源池的配置信息。 If the relay discovery process is a D2D communication process, the same UE may also carry the configuration information of the corresponding Remote UE D2D link Tx resource pool through the announcement/response message sent by the D2D communication channel (PSCCH and PSSCH).

实现方式二B：将上述通知携带在中继发现消息伴随发送的同步信道中转发给Remote UE。Embodiment 2 B: The foregoing notification is carried in the synchronization channel that is accompanied by the relay discovery message and forwarded to the Remote UE.

在覆盖外UE的Relay discovery资源池中的资源上发送Relay discovery消息时，会伴随发送同步信道和同步信号。该实现方式二B就是在这样的同步信道中携带上述通知。When the Relay discovery message is sent on a resource in the Relay discovery resource pool of the out-of-band UE, the synchronization channel and the synchronization signal are accompanied. The implementation B2 is to carry the above notification in such a synchronization channel.

承载上述通知的实现方式三：通过Relay Discovery过程之后发送的消息将上述通知转发给Remote UE。Embodiment 3 of carrying the above notification: forwarding the foregoing notification to the Remote UE by using a message sent after the Relay Discovery process.

例如，通过定义新的信道或者资源来承载Remote UE D2D link Tx资源池的配置信息，其可以Relay discovery之后进行Remote UE D2D link Tx资源池的配置。具体的传输Remote UE D2D link Tx资源池的配置信息的信道或者资源有如下几种方式：For example, the configuration information of the Remote UE D2D link Tx resource pool is carried by defining a new channel or resource, and the configuration of the Remote UE D2D link Tx resource pool can be performed after the Relay discovery. The specific channels or resources for transmitting the configuration information of the Remote UE D2D link Tx resource pool are as follows:

方式三A：采用与PSDCH相同的物理层信道结构和资源池配置方式，配置一个专用于Relay UE与Remote UE之间传输remote UE D2D link Tx资源池配置信息的PSDCH的资源池，其中该资源池中的PSDCH信道中承载的信息包括Remote UE D2D link Tx资源池配置信息。In the third mode, the resource pool of the PSDCH dedicated to the remote UE D2D link Tx resource pool configuration information between the Relay UE and the Remote UE is configured by using the same physical layer channel structure and resource pool configuration mode as the PSDCH, where the resource pool is configured. The information carried in the PSDCH channel includes the Remote UE D2D link Tx resource pool configuration information.

方式三B：采用D2D communication的信道结构(PSCCH和PSSCH)，配置一个至少用于Relay UE与Remote UE之间传输remote UE D2D link Tx资源池配置信息的D2D通信的资源池。Mode 3B: A resource pool of D2D communication for transmitting at least a remote UE D2D link Tx resource pool configuration information between the Relay UE and the Remote UE is configured by using a channel structure (PSCCH and PSSCH) of the D2D communication.

基于上述任意方法实施例，如果基站需要为不同的Relay UE配置不同的Remote UE的设备到设备链路资源池(也就是Relay UE的中继链路接收资源池)，那么，Relay UE转发给Remote UE的通知中还携带Relay UE的标识信息。Based on any of the foregoing method embodiments, if the base station needs to configure different Remote UE device-to-device link resource pools for different Relay UEs (that is, Relay UE's relay link receiving resource pool), then the Relay UE forwards to Remote. The notification of the UE also carries the identification information of the Relay UE.

基于上述任意方法实施例，可选的，接收基站为Remote UE配置的设备到设备链路资源池的通知之前，还向基站上报预配置的覆盖外UE的资源池的配置信息。The configuration information of the pre-configured resource pool of the out-of-band UE is also reported to the base station before receiving the notification of the device-to-device link resource pool configured by the remote UE.
