Description

一种传输响应消息的方法和装置 技术领域
本发明涉及无线通信技术领域，更具体地说，涉及一种传输响应消息的方法和装置。
背景技术
随着无线通信终端被应用于越来越多的场景，用户终端接入网络中继(英文：UE-to-Network relay，其中，UE是User Equipment的简称)技术应运而生。在UE-to-Network relay技术中，远程用户终端(英文：remote UE)通过中继用户终端(英文：relay UE)接入基站。例如，在一些应用场景中，中继用户终端可以是手机等智能终端，远程用户终端可以是电子手环等智能穿戴设备，智能穿戴设备可以通过智能终端作为中继接入基站。
在远程用户终端与中继用户终端进行通信的过程中，远程用户终端有时会向中继用户终端发送请求消息，中继用户终端则需要在接收之后向远程用户终端发送响应消息。例如，在中继发现的过程中，远程用户终端通过广播的方式发出请求消息，能够接收到该请求消息的中继用户终端向远程用户终端回复响应消息，这样，远程用户终端通过响应消息可以确定其附近可使用的中继用户终端。
发明人经过研究发现，在远程用户终端通过中继用户终端与基站进行通信的过程中，由于许多远程用户终端都只有一个接收射频链路，远程用户终端不能同时与基站和中继用户终端进行通信。因此，远程用户终端通常被配置为两种通信期，即基站通信周期和中继通信周期。其中，基站通信周期用于远程用户终端与基站用户终端之间进行通信，中继通信周期用于远程用户终端与中继用户终端之间进行通信。但是，针对远程用户终端发送的请求消息，中继用户终端时常会在远程用户终端的基站通信周期向远程用户终端回复响应消息，而远程用户终端在其基站通信周期中并不监听中继用户终端发送的消息，因此，中继用户终端回复的响应消息时常无法被远程用户终端监听到，从而远程用户终端所请求的业务的失败概率就会增加。

具体实施方式
发明人经过研究发现，在接收到远程用户终端发送的请求消息之后，中继用户终端需要使用基站分配的资源向远程用户终端发送响应消息。但是，一方面，基站在为中继用户终端分配资源用于发送响应消息的资源时并不知晓用于接收响应消息的远程用户终端，因此，基站向中继用户终端分配的资源不能保证一定是在远程用户终端的中继通信周期内的资源。另一方面，即使基站为中继用户终端分配了多个可供选择的资源，由于中继用户终端并不知晓远程用户终端的通信周期配置情况，即中继用户终端并不知晓远程用户的中继通信周期，因此，中继用户终端为回复响应消息而选择的资源也不能保证一定是在远程用户终端的中继通信周期内的资源。由此可见，中继用户终端不能避免使用 远程用户终端的基站通信周期内的资源向远程用户终端回复响应消息的情况，因此，中继用户终端时常会在远程用户终端的基站通信周期向远程用户终端回复响应消息，而远程用户终端在其基站通信周期中并不监听中继用户终端发送的消息，因此，中继用户终端回复的响应消息时常无法被远程用户终端监听到，从而远程用户终端所请求的业务的失败概率就会增加。
基于此，在本发明实施例的一个方面中，中继用户终端向基站请求分配用于发送响应消息的资源时，在中继用户终端发送的资源请求中可以携带有远程用户终端发送的指示信息，所述指示信息可以用于基站确定远程用户终端的中继通信周期。因此，基站根据所述指示信息能够保证在远程用户终端的中继通信周期内的资源中分配用于中继用户终端发送响应消息的资源。在本发明实施例的另一个方面中，远程用户终端向基站请求分配用于发送请求消息的资源时同时请求用于发送响应消息的资源，基站可以根据远程用户终端的资源请求向远程用户终端分配用于发送请求消息的资源和用于发送响应消息的资源，远程用户终端再将用于发送响应消息的资源发送给中继用户终端使用。由于远程用户终端发送的资源请求可以用于基站确定远程用户终端的中继通信周期，因此，基站根据远程用户终端发送的资源请求能够保证在远程用户终端的中继通信周期内的资源中分配出的用于发送响应消息的资源。由此可见，通过中继用户终端的资源请求中携带的指示信息或远程用户终端的资源请求，基站能够确定远程用户终端的中继通信周期并能够保证分配给中继用户终端用于发送响应消息的资源一定是远程用户终端的中继通信周期内的资源，因此，中继用户终端就能够保证在远程用户终端的中继通信周期内向远程用户终端回复对应于请求消息的响应消息，从而远程用户终端无法监听到响应消息的情况得以避免，从远程用户终端所请求的业务的失败概率得以降低。
举例来说，本发明实施例的场景之一，可以是应用到如图1所示的网络系统中。在所述网络系统中，远程用户终端101可以与中继用户终端102之间进行通信，中继用户终端102与基站103之间可以进行通信，远程用户终端101与基站103之间可以进行通信。
基于图1所示的网络系统，作为一种示例，远程用户终端101可以向中继用户终端102发送携带有指示信息的请求消息。中继用户终端102可以从请求 消息中获取所述指示信息并向基站103发送携带有所述指示消息的资源请求，以请求基站103分配用于发送响应消息的资源。基站103在接收到所述资源请求之后，可以根据所述指示信息确定远程用户终端101的中继通信周期并向所述中继用户终端102分配所述中继通信周期内的第一初始资源。中继用户终端102在接收到所述第一初始资源之后，可以根据所述第一初始资源确定第一目标资源并使用所述第一目标资源向所述远程用户终端101发送对应于所述请求消息的响应消息。
基于图1所示的网络系统，作为另一种示例，远程用户终端101可以向基站103发送资源请求，以请求基站103分配用于发送请求消息的资源和用于发送响应消息的资源。基站103可以根据所述资源请求确定远程用户终端101的中继通信周期并向远程用户终端101分配第一目标资源和所述中继通信周期内的初始资源。远程用户终端101在接收到所述第一目标资源和所述初始资源之后，可以根据已保存的中继用户终端的标识，使用所述第一目标资源向所述中继用户终端发送携带有所述初始资源的请求消息。中继用户终端102在接收到请求消息之后，可以根据初始资源确定第二目标资源并使用第二目标资源向远程用户终端101发送对应于所述请求消息的响应消息。
可以理解的是，上述场景仅是本发明实施例提供的一个场景示例，本发明实施例并不限于此场景。
需要说明的是，在本发明实施例中，所涉及的术语“资源”，也可称为时频资源，具体可以表示用于信息传输的时频位置。在本发明实施例所涉及的描述中，分配用于发送“消息”的“资源”，表示，配置该“资源”所表示的时频位置用于发送该“消息”。发送“资源”，表示，发送该“资源”所表示的时频位置的标识。使用“资源”发送“消息”，表示，在该“资源”所表示的时频位置上发送该“消息”。其中，所述“资源”可以是用于发送请求消息的资源，也可以是用于发送响应消息的资源，还可以是其他资源。所述“消息”可以是请求消息，也可以是响应消息，还可以是其他消息。
此外，在基站通信周期中，远程用户终端可以通过蜂窝链路与基站进行通信。在中继通信周期中，远程用户终端可以通过sidelink与中继用户终端进行 通信。其中，基站例如可以是演进型基站(英文：Evolutional Node B，简称eNB)。
下面结合附图，通过实施例来详细说明本发明实施例中传输响应消息的方法与相关设备的具体实现方式。
参见图2，示出了本发明实施例中一种传输响应消息的方法的流程示意图。本实施例的方法从中继用户终端的角度进行介绍，其中，在中继用户终端发送的资源请求中携带有远程用户终端发送的指示信息，所述指示信息可以用于确定远程用户终端的中继通信周期。具体地，本实施例的方法例如可以包括以下步骤：
201、中继用户终端接收远程用户终端发送的请求消息，所述请求消息携带有指示信息。
具体实现时，远程用户终端可以向基站发送对应于请求消息的资源请求，以请求基站分配用于发送请求消息的资源。基站在针对该资源请求分配了用于发送请求消息的资源之后，可以向远程用户终端发送该用于发送请求消息的资源。远程用户终端在接收到该用于发送请求消息的资源之后，可以在该资源所表示的时频位置上向中继用户终端发送请求消息，以便中继用户终端接收。可以理解的是，为了请求基站分配用于发送请求消息的资源，远程用户终端与基站之间存在通信，因此，远程用户终端此时是处于无线资源控制(英文：Radio Resource Control，简称RRC)连接态。
其中，对应于请求消息的资源请求，具体可以是嵌入在旁链接用户终端信息(英文：SidelinkUEInformation)中进行发送，也即，远程用户终端向基站发送的SideUEInformation中携带有对应于请求消息的资源请求。用于发送请求消息的资源，具体可以是嵌入在无线资源控制连接重配置(英文：RRCConnectionReconfiguration，)信息，也即，在基站向远程用户终端发送的RRCConnectionReconfiguration中携带有用于发送请求消息的资源。
需要说明的是，所述指示信息具有两方面的特点，一方面的特点在于远程用户终端能够提供所述指示信息，另一方面的特点在于所述指示信息能够用于指示基站确定远程用户终端的中继通信周期。具有上述两方面特 点的信息可以用作所述指示信息。
作为一种示例，所述指示信息可以为所述远程用户终端的标识。一方面，远程用户终端是具有其自身的标识，也即，远程用户终端能够提供其本身的标识。另一方面，由于远程用户终端的通信周期是由基站配置的，基站中保存有远程用户终端的周期配置信息，该周期配置信息与远程用户终端的标识具有对应关系，并且，在该周期配置信息中记录有远程用户终端的中继通信周期。因此，基站根据远程用户终端的标识以及与远程用户终端对应的配置信息，能够确定远程用户终端的中继通信周期。可见，所述远程用户终端的标识具有上述两方面的特点，故可以用作所述指示信息。
作为又一种实例，所述指示信息可以为所述远程用户终端的周期配置信息，所述周期配置信息用于指示所述远程用户终端的中继通信周期。一方面，远程用户终端需要执行其本身的通信周期，因此，远程用户终端中保存有其本身的周期配置信息，也即，远程用户终端能够提供其本身的周期配置信息。另一方面，远程用户终端的周期配置信息中记录有远程用户终端的中继通信周期，因此，基站根据远程用户终端的周期配置信息能够确定远程用户终端的中继通信周期。可见，所述远程用户终端的标识具有上述两方面的特点，故可以用作所述指示信息。
202、所述中继用户终端向基站发送携带有所述指示信息的资源请求，以便所述基站根据所述指示信息确定所述远程用户终端的中继通信周期并向所述中继用户终端分配所述中继通信周期内的第一初始资源。
具体实现时，中继用户终端接收到请求消息之后，可以获取请求消息中携带的指示信息，在对应于响应消息的资源请求中嵌入指示消息，并向基站发送对应于响应消息的资源请求，以请求基站分配用于发送响应消息的资源。基站在接收到该资源请求之后，根据该资源请求中携带的指示信息，可以确定远程用户终端的中继通信周期，进而可以从该中继通信周期内的资源中分配用于中继用户终端发送响应消息的资源，并以所分配的资源作为第一初始资源向中继用户终端发送。
可以理解的是，基站确定中继通信周期的方式与基站接收到的指示信息有关。在不同的实施方式中，若接收到不同的指示信息，则基站确定中 继通信的方式可能也不同。
作为一种示例，基站接收到的指示信息可以是远程用户终端的标识。基站根据远程用户终端的标识，可以从自身保存的周期配置信息中查找出与远程用户终端的标识相对应的周期配置信息。该周期配置信息即是远程用户终端的配置信息，记录有远程用户终端的中继通信周期。因此，基站通过读取远程用户终端的周期配置信息，可以确定远程用户终端的中继通信信息。
作为又一种示例，基站接收的指示信息可以是远程用户终端的周期配置信息。基站从对应于响应消息的资源请求中获取远程用户终端的周期配置。由于远程用户终端的周期配置信息记录有远程用户终端的中继通信周期，基站通过读取该周期配置信息可以确定远程用户终端的中继通信周期。
在本实施例中，所述中继通信周期可以是多种不同周期配置方式下用于远程用户终端与中继用户终端通信的周期。
作为一种示例，基站可以采用非连续接收(英文：Discontinuous Reception，简称DRX)的配置方式为远程用户终端配置通信周期。其中，中继通信周期为DRX休眠期，基站通信周期为DRX激活期。DRX休眠期和DRX激活期可以是由基站为远程用户终端配置并下发给远程用户终端的。
作为另一种示例，基站可以采用间隔期(英文：gap)的配置方式为远程用户终端配置中继通信周期，也即，中继通信周期为间隔期。例如，在中继发现的技术场景中，中继通信周期具体为发现间隔期(英文：discovery gap)。远程用户终端可以根据自身需求向基站发送间隔期(英文：gap)请求，基站则可以将远程用户终端请求的间隔期配置用于远程用户终端与中继用户终端之间进行通信。
在本实施例中，基站可以采用多种不同的方式向中继用户终端分配用于发送响应消息的资源。
作为一种示例，基站可以分配多个资源以供中继用户终端选择用于发送响应消息。具体地，基站可以向中继用户终端分配中继通信周期内的多个资源作为第一初始资源，多个第一初始资源可以用于中继用户终端从中 选取用于发送响应消息的第一目标资源。其中，基站可以通过分配资源池(英文：Resource pool)的方式实现多个第一初始资源的分配。具体地，基站可以向中继用户终端分配中继通信周期内的一个资源池，该资源池中具有多个资源并且该资源池的每一个资源都位于中继通信周期内，可见，该资源池中包含的资源即是第一初始资源。中继用户终端可以在该资源池中选择一个资源用于发送响应消息，也即，中继用户终端在该资源池中选择出的资源即为第一目标资源。
作为又一种示例，基站可以分配一个资源以指定中继用户终端用于发送响应消息。具体地，基站可以向中继通信用户分配中继通信周期内的一个资源作为第一初始资源，第一初始资源是指定中继用户终端用于发送响应消息的资源，也即，第一初始资源是指定中继用户终端作为第一目标资源使用的资源。其中，第一初始资源可以是中继通信周期内的一个专用资源(英文：dedicated resource)，基站可以在中继通信周期内的一个资源池中指定一个专用资源，以便中继用户终端使用该专用资源发送响应消息。也即，该专用资源即是第一初始资源，也是第一目标资源。其中，专用资源例如可以是在基站向中继用户终端发送的SL-grant中指定的。
在202中，为了请求基站分配用于发送响应消息的资源，中继用户终端与基站之间存在通信，因此，中继用户终端此时需处于RRC连接态。可以理解的是，在201之后，中继用户终端接收到远程用户终端发送的请求消息，此时中继用户终端可能处于RRC空闲态也可能处于RRC连接态。若在201之后中继用户终端处于RRC连接态，则中继用户终端可以在不进行状态切换的情况下直接执行202。若在201之后中继用户终端处于RRC空闲态，则中继用户终端可以先从RRC空闲态切换成RRC连接态再执行202。
需要说明的是，基站有时会向中继用户终端分配可供中继用户自主选择的资源，之后，在中继用户终端与远程用户终端通信时，若中继用户终端处于RRC空闲态，中继用户终端可以不向基站请求资源而是在基站此前分配的资源中自主选择用于向远程用户终端发送消息的资源，这样中继用户终端可以不必从RRC空闲态切换成RRC连接态，从而避免了在RRC连 接态消耗过多资源和功率的问题。具体到本实施例，若指示信息为远程用户终端的周期配置信息，中继用户终端通过接收请求消息，可以从请求消息中读取到远程用户终端的周期配置信息，从而确定远程用户终端的中继通信周期。可见，在指示消息为远程用户终端的周期配置信息的情况下，中继用户终端能够选取出在远程用户终端的中继通信周期内的资源。基于此，在本实施例的一些实施方式中，在指示消息为远程用户终端的周期配置信息的情况下，若在接收到请求消息之后中继用户终端处于RRC空闲态，中继用户终端可以先在保持RRC空闲态的情况下在基站分配的资源中查找远程用户终端的中继通信周期内的资源，若无法查找到再切换成RRC连接态以请求基站分配资源。具体地，参见图3，在201之后，本实施例例如还可以包括：
301、若所述中继用户终端处于无线资源控制RRC空闲态并已保存有所述基站分配的所述中继通信周期内的第二初始资源，所述中继用户终端根据所述周期配置信息，在所述第二初始资源中选取第二目标资源，并使用所述第二目标资源向所述远程用户终端发送对应于所述请求消息的响应消息。
具体实现时，在中继用户终端处于RRC空闲态之前，基站向中继用户终端分配了可供中继用户终端自主选择资源的资源池，之后，中继用户终端在处于RRC空闲态时接收到远程用户终端发送的请求消息，可以从请求消息中读取远程用户终端的周期配置信息，从而确定出远程用户终端的中继通信周期。接着，中继用户终端可以在基站此前分配的资源池中查找该中继通信周期内的资源。若能够查找到，以查找到的资源作为第二初始资源，中继用户终端可以在第二初始资源中选取一个资源作为第二目标资源并在第二目标资源所表示的时频位置上发送对应于请求消息的响应消息。
其中，基站可以通过广播系统消息块(英文：System Information Block，简称SIB)的方式向中继用户终端分配可供其自主选择使用的资源，所分配的资源可以是携带在SIB18或SIB19中，可见，若所分配的资源中存在远程用户的中继通信周期内的第二初始资源，则第二初始资源是携带在SIB18或SIB19中下发到中继用户终端的。
可以理解的是，在301中，中继用户终端用于发送响应消息的第二目标资源并非中继用户终端请求基站分配的，因此，在远程用户终端的中继通信周期为DRX休眠期的情况下，在301之前，基站接收到远程用户终端发送的对应于请求资源的资源请求时，可以将此后的一段时间作为远程用户终端的非调度期，并在远程用户终端的非调度期内不对远程用户终端进行调度，从而使得在远程用户终端的非调度期内远程用户终端的DRX休眠期不会因基站的调度而改变，使得在中继用户终端确定出的DRX休眠期中远程用户终端能够监听到中继用户终端回复的响应消息。
302、若所述中继用户终端处于无线资源控制RRC连接态或未保存有所述基站分配的所述中继通信周期内的资源，所述中继用户终端执行202。
可以理解的是，在302中，中继用户终端执行202的前提条件是中继用户终端处于RRC连接态或未保存有所述基站分配的所述中继通信周期内的资源。也即，若中继用户终端处于RRC连接态，则即使中继用户终端是否保存有基站分配的位于中继通信周期内的资源，中继用户终端都执行202。若中继用户终端未保存有基站分配的位于中继通信周期内的资源，则无论中继用户终端处于RRC连接态还是处于RRC空闲态，中继用户终端都执行202。
需要说明的是，多种情况会导致中继用户终端在处于RRC空闲态的情况下未保存有基站分配的中继通信周期内的资源。一种情况在于，在中继用户终端处于空闲态之前基站并未向中继用户终端分配可供其自主选择资源的资源池。另一种情况在于，虽然在中继用户终端处于空闲态之前基站向中继用户终端分配了可供其自主选择资源的资源池，但该资源池中的资源都不位于远程用户终端的中继通信周期内。
具体实现时，在201之后，中继用户终端可以先判断自身是否处于空闲态，若否则执行202。若是则中继用户终端查找基站分配的资源池，若无法查找到则执行302。若能够查找到则中继用户终端在基站分配的资源池中查找中继通信周期内的资源，若无法查找到则执行302，若能够查找到则执行301。
接着返回图2。
S203、所述中继用户终端根据所述第一初始资源确定第一目标资源并使用所述第一目标资源向所述远程用户终端发送对应于所述请求消息的响应消息。
具体实现时，中继用户终端在接收到第一初始资源之后，可以从第一初始资源中确定出第一目标资源，并在第一目标资源所表示的时频位置上向远程用户终端发送响应消息，以便远程用户终端接收。
可以理解的是，对应于基站分配第一初始资源的不同方式，中继用户终端可以采用不同的方式确定第一目标资源。
作为一种示例，若基站可以分配多个第一初始资源以供中继用户终端选择，则中继用户终端可以在多个第二初始资源中选取一个第一目标资源，以用于发送响应消息。具体地，203中第一目标资源的确定方式，例如具体可以为：所述中继用户终端在多个所述第一初始资源中选取一个资源作为所述第一目标资源；其中，所述基站向所述中继用户终端分配的是多个可被所述中继用户终端选择使用的第一初始资源。例如，基站可以向中继用户终端分配一个包含多个第一初始资源的资源池，中继用户终端可以在该资源池中选取一个资源作为第一目标资源。
作为又一种示例，若基站分配一个第一初始资源以指定中继用户终端使用，则中继用户终端可以直接将该第一初始资源作为第一目标资源，用于发送响应消息。具体地，203中第一目标资源的确定方式，例如具体可以为：所述中继用户终端将所述第一初始资源确定为所述第一目标资源；其中，所述基站向所述中继用户终端分配的是一个指定所述中继用户终端使用的所述第一初始资源。例如，基站可以向中继用户终端从一个资源池中分配一个中继通信周期内的专用资源，中继用户终端可以使用该专用资源发送响应消息，即，该专用资源即是第一初始资源也是第一目标资源。
需要说明的是，本实施例可以涉及多种不同技术场景下远程用户终端与中继用户终端之间交互请求消息和响应消息。
例如，一种示例性的技术场景可以是中继发现过程。其中，所述请求消息为用于中继发现的请求消息，即Solicitation。所述响应消息为用于中继发现的响应消息，即Response。远程用户终端通过广播Solicitation，向 能够接收到Solicitation的中继用户终端请求接入。能够接收到Solicitation的中继用户终端向远程用户终端回复Response，以通知远程用户终端其自身可用于接入。远程用户终端接收到一个或多个中继用户终端的Response，从而在其中选择一个中继用户终端发起接入。
又如，又一种示例性的技术场景可以是直连通信链接建立过程。其中，所述请求消息为用于直连通信链路建立的请求消息，或者也可称为直连通信链路建立请求。所述响应消息为用于直连通信链路建立的响应消息，即Response。远程用户终端向中继用户终端发送直连通信链路建立请求之后，中继用户终端与远程用户终端之间进行认证和安全信息的建立，在认证通过且安全信息建立之后，中继用户终端向远程与用户终端发送Response。
在本实施例中，中继用户终端向基站请求分配用于发送响应消息的资源时，在中继用户终端发送的资源请求中可以携带有远程用户终端发送的指示信息，所述指示信息可以用于基站确定远程用户终端的中继通信周期。因此，基站根据所述指示信息能够保证在远程用户终端的中继通信周期内的资源中分配用于中继用户终端发送响应消息的资源。由此可见，通过中继用户终端的资源请求中携带的指示信息，基站能够确定远程用户终端的中继通信周期并能够保证分配给中继用户终端用于发送响应消息的资源一定是远程用户终端的中继通信周期内的资源，因此，中继用户终端就能够保证在远程用户终端的中继通信周期内向远程用户终端回复对应于请求消息的响应消息，从而远程用户终端无法监听到响应消息的情况得以避免，从远程用户终端所请求的业务的失败概率得以降低。
参见图4，示出了本发明实施例中一种传输响应消息的方法的流程示意图。本实施例的方法从基站的角度进行介绍，其中，在中继用户终端发送的资源请求中携带远程用户终端发送的指示信息，所述指示信息用于基站确定远程用户终端的中继通信周期。具体地，本实施例的方法例如可以包括以下步骤：

在本实施例中，通过中继用户终端的资源请求中携带的指示信息，基站能够确定远程用户终端的中继通信周期并能够保证分配给中继用户终端 用于发送响应消息的资源一定是远程用户终端的中继通信周期内的资源，因此，中继用户终端就能够保证在远程用户终端的中继通信周期内向远程用户终端回复对应于请求消息的响应消息，从而远程用户终端无法监听到响应消息的情况得以避免，从远程用户终端所请求的业务的失败概率得以降低。
参见图5，示出了本发明实施例中一种传输响应消息的方法的流程示意图。本实施例的方法从远程用户终端的角度进行介绍，其中，在中继用户终端发送的资源请求中携带有远程用户终端发送的指示信息，所述指示信息用于基站确定远程用户终端的中继通信周期。具体地，本实施例的方法例如可以包括以下步骤：

需要说明的是，本实施例与图2所示的实施例是相对应的，两者的区别在于，本实施例从远程用户终端的角度进行介绍而图2所示的实施例从 中继用户终端开始介绍。因此，本实施例相关内容可参见图2所示的实施例的介绍。其中，本实施例中提及的“初始资源”对应于图2所示的实施例中提及的“第一初始资源”，本实施例中提及的目标资源对应于图2所示的实施例中提及的“第一目标资源”。
在本实施例中，通过中继用户终端的资源请求中携带的指示信息，基站能够确定远程用户终端的中继通信周期并能够保证分配给中继用户终端用于发送响应消息的资源一定是远程用户终端的中继通信周期内的资源，因此，中继用户终端就能够保证在远程用户终端的中继通信周期内向远程用户终端回复对应于请求消息的响应消息，从而远程用户终端无法监听到响应消息的情况得以避免，从远程用户终端所请求的业务的失败概率得以降低。
参见图6，示出了本发明实施例中一种传输响应消息的方法的流程示意图。本实施例的方法从远程用户终端的角度进行介绍，其中，远程用户终端向基站请求分配用于发送请求消息的资源时同时请求用于发送响应消息的资源，基站可以根据远程用户终端的资源请求可以向远程用户终端分配用于发送请求消息的资源和用于发送响应消息的资源。具体地，本实施例的方法例如可以包括以下步骤：
601、远程用户终端向基站发送资源请求，以便所述基站根据所述资源请求确定所述远程用户终端的中继通信周期并向所述远程用户终端分配第一目标资源和所述中继通信周期内的初始资源。
具体实现时，远程用户终端可以向基站发送资源请求，以请求基站分配用于远程用户终端自身发送请求消息的资源以及用于中继用户终端发送响应消息的资源。基站根据远程用户终端发送的资源请求可以识别出远程用户终端本身，并且，由于远程用户终端的通信周期是由基站配置的，基站中保存有远程用户终端的周期配置信，在该周期配置信息中记录有远程用户终端的中继通信周期。因此，基站根据远程用户终端发送的资源请求，能够查找到远程用户终端的周期配置信息，从而通过读取远程用户终端的周期配置信息能够确定远程用户终端的中继通信周期。在确定远程用户终 端的中继通信周期之后，基站可以在所述中继通信周期内的资源中分配出第一目标资源和初始资源并向远程用户终端发送，其中，第一目标资源用于远程用户终端发送请求消息，初始资源用于中继用户终端从中确定用于发送响应消息的第二目标资源。
可以理解的是，为了请求基站分配资源，远程用户终端与基站之间存在通信，因此，远程用户终端此时是处于无线资源控制(英文：Radio Resource Control，简称RRC)连接态。
602、所述远程用户终端根据已保存的中继用户终端的标识，使用所述第一目标资源向所述中继用户终端发送携带有所述初始资源的请求消息，以便所述中继用户终端根据所述初始资源确定所述第二目标资源。
具体实现时，对于曾经连接过的中继用户终端，远程用户终端中保存有其标识，例如，远程用户终端中可以保存有中继用户终端的临近服务(英文：Proximity Service，简称ProSe)标识(英文简称：ID)。远程用户终端在接收到第一目标资源和初始资源之后，可以在选取一个其已保存的中继用户终端的标识，在第一目标资源所标识的时频位置上向该标识对应的中继用户终端发送携带有初始资源的请求消息。中继用户终端在接收到请求消息之后，可以从请求消息中获取初始资源，并从初始资源中确定一个第二目标资源，以用于发送响应消息。
可选的，所述基站可以向所述中继用户终端分配的是多个可被所述中继用户终端选择使用的初始资源，多个所述初始资源可以用于所述中继用户终端从中选取所述第二目标资源。
可选的，所述基站可以向所述中继用户终端分配的是一个指定所述中继用户终端使用的所述初始资源，所述初始资源可以是指定所述中继用户终端作为所述第二目标资源使用的资源。
603、所述远程用户终端接收所述中继用户终端使用所述第二目标资源发送的响应消息，所述响应消息对应于所述请求消息。
具体实现时，中继用户终端可以在第二目标资源所表示的时频位置上向远程用户终端发送对应于请求消息的响应消息。
可选的，所述中继通信周期具体为所述基站为所述远程用户终端配置 的非连续接收DRX休眠期。
可选的，所述请求消息为用于中继发现的请求消息，或者，所述请求消息为用于直连通信链路建立的请求消息。
需要说明的是，本实施例与图2所示的实施例之间的区别在于，在本实施例中，用于中继用户终端发送响应消息的资源，是远程用户终端在发送请求消息之前向基站请求分配并在发送请求消息时发送给中继用户终端的，中继用户终端不必再请求基站分配用于发送响应消息的资源，而图2所示的实施例中，用于中继用户终端发送响应消息的资源，是中继用户终端在接收到远程用户终端发送的请求消息之后向基站请求分配的，在远程用户终端发送的请求消息以及中继用户终端发送的资源请求中携带有指示信息。除了上述区别之外，本实施例其余部分的相关内容可参见图2所示的实施例的介绍。其中，本实施例中提及的“初始资源”对应于图2所示的实施例中提及的“第一初始资源”，本实施例中提及的“第二目标资源”对应于图2所示的实施例中提及的“第一目标资源”。
在本实施例中，远程用户终端向基站请求分配用于发送请求消息的资源时同时请求用于发送响应消息的资源，基站可以根据远程用户终端的资源请求可以向远程用户终端分配用于发送请求消息的资源和用于发送响应消息的资源，远程用户终端再将用于发送响应消息的资源发送给中继用户终端使用。由于远程用户终端发送的资源请求可以用于基站确定远程用户终端的中继通信周期，因此，基站根据远程用户终端发送的资源请求能够保证在远程用户终端的中继通信周期内的资源中分配出的用于发送响应消息的资源。由此可见，通过远程用户终端的资源请求，基站能够确定远程用户终端的中继通信周期并能够保证分配给中继用户终端用于发送响应消息的资源一定是远程用户终端的中继通信周期内的资源，因此，中继用户终端就能够保证在远程用户终端的中继通信周期内向远程用户终端回复对应于请求消息的响应消息，从而远程用户终端无法监听到响应消息的情况得以避免，从远程用户终端所请求的业务的失败概率得以降低。
