其中，网络设备可以为通用移动通信系统(Universal Mobile Telecommunications System，UMTS)或长期演进(Long Term Evolution，LTE)无线通信系统中的宏基站，如演进基站(Evolved NodeB，eNB)；也可以为在异构网络(Heterogeneous Network，HetNet)场景中的微基站；还可以为分布式基站场景中的基带处理单元(Base Band Unit，BBU)和远端射频单元(Remote Radio Unit，RRU)；还可以为云接入网(Cloud Radio Access Network，CRAN)场景中基带单元池(BBU pool)和RRU；还可以为未来5G无线通信系统中的gNB；还可以为无线局域网中的站点，如无线保真(WIreless-Fidelity，WiFi)系统中的WiFi站点(station)。

下述结合多个实施例对本申请实施例提供的通信方法进行举例说明。
图2为本申请实施例提供的一种信息传输方法的流程图一。该信息传输方法可由第一通信设备、网络设备及第二通信设备交互执行。如图2所示，该信息传输方法可 包括：
S201、第一通信设备在第一资源上向网络设备发送第一请求消息。
该第一通信设备可称为源通信设备或者发送端的通信设备，第二通信设备可称为目的通信设备或者接收端的通信设备。
该第一请求消息用于请求该网络设备调度该第一通信设备与该第二通信设备进行侧行信息传输的资源。该第一通信设备和该第二通信设备可属于一个组播组，该第一资源可以为该组播组对应的发送请求消息的资源。
该第一通信设备可在该第一资源上通过上行链路向网络设备发送该第一请求消息。该第一请求消息可用于请求网络设备调度该第一通信设备和第二通信设备进行侧行信息传输的资源，即调度该第一通信设备在该资源上进行该侧行信息的发送，调度该第二通信设备在该资源上进行该侧行信息的接收。
在该实施例提供的信息传输方法，第一通信设备可在向网络设备发送的该第一请求消息的过程中，通过隐含指示的方式，向网络设备指示该第二通信设备。由于该第一资源为第一组播组对应的发送请求消息的资源，而该第一通信设备和该第二通信设备均属于该组播组，则在该信息传输方法，可通过该第一请求消息所在的资源，即该第一资源，向网络设备隐含指示该组播组，进而隐含指示该第二通信设备。
该第一资源可以包括时频资源、空间资源和码序列资源等至少一种类型的资源。不同组播组可对应不同的发送请求消息的资源。
若该第一请求消息为调度请求(Scheduling Request，SR)消息，则该第一资源还可称为该组播组所对应的SR资源。
其中，该侧行信息可以为侧行链路上的传输信息，如侧行控制信息，侧行数据信息，或侧行应答信息等任一。
S202、网络设备接收来自第一通信设备发送的该第一请求消息。
S203、网络设备根据该第一请求消息所在的该第一资源，以及该第一资源与组播组的对应关系，确定该第一资源对应的组播组，该第一通信设备和该第二通信设备属于该组播组。
也就是说，该网络设备在确定该组播组的情况下，便确定了该第二通信设备，例如可将该组播组中，该第一通信设备外的其它通信设备确定为该第二通信设备。
S204、网络设备调度该第一通信设备和第二通信设备进行该侧行信息传输的第二资源。
该网络设备在确定该第一通信设备及该第二通信设备的情况下，便可调度该第一通信设备和第二通信设备进行该侧行信息传输的第二资源，即调度该第一通信设备在该第二资源上进行该侧行信息的发送，调度该第二通信设备在该第二资源上进行该侧行信息的接收，而避免调度该第二通信设备进行侧行信息的发送。
该网络设备调度该第一通信设备和该第二通信设备进行该侧行信息传输的该第二资源，即分配该第二资源用于该第一通信设备向该第二通信设备发送该侧行信息。
S205、网络设备向第一通信设备发送第一指示信息，该第一指示信息用于指示该第二资源。
该第一指示信息可携带在调度授予(Scheduling Grant，SG)控制消息中。
网络设备在向第一通信设备发送的第一指示信息的过程中，还可通过显性指示或隐性指示的方式，向第一通信设备指示当前调度对应的第二通信设备。若为显性指示方式，则在该第一指示信息中，可包括有该第二通信设备的标识信息；若为隐性指示方式，则该第一指示信息中，可不包括该第二通信设备的标识信息，而通过由该第二通信设备的标识信息对该第一指示信息进行加密或加扰的方式进行隐含指示。
该网络设备可在下行链路上向该第一通信设备发送该第一指示信息。
S206、第一通信设备接收来自网络设备的第一指示信息。
S207、第一通信设备在该第二资源上向第二通信设备发送该侧行信息。
该第一通信设备可在该第二资源上，通过侧行链路向第二通信设备发送该侧行信息。
由于网络设备调度该第一通信设备进行该侧行信息的发送，调度该第二通信设备进行该侧行信息的接收，避免了调度该第二通信设备的标识信息发送，可有效保证第一通信设备向第二通信设备所发送的该侧行信息的可达性。
本申请实施例提供的信息传输方法，可通过第一通信设备在第一资源上向网络设备发送第一请求消息，使得网络设备调度该第一通信设备与第二通信设备进行侧行信息传输的资源，该第一通信设备与该第二通信设备属于一个组播组，该第一资源为该组播组对应的发送请求消息的资源；网络设备还向第一通信设备返回第一指示信息，该第一指示信息用于指示该网络设备调度的该第一通信设备与该第二通信设备进行该侧行信息传输的第二资源，使得第一通信设备在接收到该第一指示信息后，便可在该第二资源上向该第二通信设备发送该侧行信息。由于该方法中，可通过第一通信设备向网络设备发送第一请求消息，使得网络设备调度该第一通信设备与该第二通信设备进行侧行信息传输的资源，避免了调度第二通信设备进行信息发送，可有效保证第一通信设备向第二通信设备所发送的侧行信息的可达性，有效解决了侧行链路上半双工问题所引起的信息不可达问题。
同时，该信息传输方法中，由于该第一资源为该第一通信设备以及该第二通信设备所在的组播组对应的发送请求消息的资源，因而，该信息传输方法可适用于通信设备之间的组播传输场景。该第一通信设备通过该第一请求消息向网络设备请求调度的过程中，通过该第一请求消息所在的资源，即该第一资源，向网络设备隐含指示该第二通信设备，可在保证第一通信设备向第二通信设备所发送的侧行信息的可达性的基础上，还减少了第一请求消息中携带的信息量，减少了请求消息的变动，提高了方法的适用性。
在一种可能示例中，在如上所示的信息传输方法中，该第一资源可以为预设的资源。
在另一种可能示例中，在如上所示的信息传输方法中，该第一资源可以为网络设备所配置的资源啊，则S201中第一通信设备在第一资源上向网络设备发送第一请求消息之前，该方法还可包括：
网络设备向第一通信设备发送第二指示信息，该第二指示信息用于指示该第一资源；
第一通信设备接收来自网络设备的该第二指示信息。
该第一资源例如可包括：时频资源、空间资源和码序列资源等至少一种类型的资源。
该网络设备例如可根据该第一通信设备所在的组播组，以及预设的组播组与资源的对应关系，确定该组播组对应的资源为该第一资源，并向该第一通信设备发送该第二指示信息，从而实现网络设备对该第一资源的配置。
本申请实施例还可提供一种信息传输方法。图3为本申请实施例提供的一种信息传输方法的流程图二。该信息传输方法可由第一通信设备、网络设备及第二通信设备交互执行。该如图3所示，该信息传输方法，可包括：
S301、第一通信设备向网络设备发送第二请求消息，该第二请求消息包括：该第二通信设备的标识信息。
该第二请求消息用于请求该网络设备调度该第一通信设备与该第二通信设备进行侧行信息传输的资源。其中，该侧行信息可以为侧行链路上的传输信息，如侧行控制信息，侧行数据信息，或侧行应答信息等任一。该第二请求消息例如可以为缓存状态报告(Buffer Status Report，BSR)消息。
该第二请求消息也可用于请求网络设备调度该第一通信设备和第二通信设备进行侧行信息传输的资源，即调度该第一通信设备在该资源上进行该侧行信息的发送，调度该第二通信设备在该资源上进行该侧行信息的接收。
在该实施例提供的信息传输方法，第一通信设备可在向网络设备发送的该第二请求消息的过程中，通过该第二请求消息所包括的该第二通信设备的标识信息，向网络设备明确指示该第二通信设备。
S302、网络设备接收来自第一通信设备的该第二请求消息。
S303、网络设备调度该第一通信设备与该第二通信设备传输该侧行信息的第三资源。
该网络设备可在接收到该第二请求消息的情况下，根据该第二请求消息所包括的该第二通信设备的标识信息，确定该第二通信设备，继而调度该第一通信设备和第二通信设备进行该侧行信息传输的第三资源，即调度该第一通信设备在该第三资源进行该侧行信息的发送，调度该第二通信设备在该第三资源上进行该侧行信息的接收，而避免调度该第二通信设备进行侧行信息的发送。
该网络设备调度该第一通信设备和该第二通信设备进行该侧行信息传输的该第三资源，即分配该第三资源用于该第一通信设备向该第二通信设备发送该侧行信息。
S304、网络设备向第一通信设备发送第三指示信息，该第三指示信息用于指示该第三资源。
该第三指示信息也可携带在SG控制消息中。
网络设备在向第一通信设备发送的第三指示信息的过程中，还可通过显性指示或隐性指示的方式，向第一通信设备指示当前调度对应的第二通信设备。若为显性指示方式，则在该第三指示信息中，可包括有该第二通信设备的标识信息；若为隐性指示方式，则该第三指示信息中，可不包括该第二通信设备的标识信息，而通过由该第二通信设备的标识信息对该第三指示信息进行加密或加扰的方式进行隐含指示。
S305、第一通信设备接收来自网络设备的该第三指示信息。
S306、第一通信设备在该第三资源上向第二通信设备发送该侧行信息。
该第一通信设备可在该第三资源上，通过侧行链路向第二通信设备发送该侧行信息。
由于网络设备调度该第一通信设备进行该侧行信息的发送，调度该第二通信设备进行该侧行信息的接收，避免了调度该第二通信设备的标识信息发送，可有效保证第一通信设备向第二通信设备所发送的该侧行信息的可达性。
本申请实施例提供的信息传输方法，可通过第一通信设备向网络设备发送第二请求消息，使得网络设备调度该第一通信设备与第二通信设备进行侧行信息传输的资源，该第二请求消息包括该第二通信设备的标识信息；网络设备还向第一通信设备返回第三指示信息，该第三指示信息用于指示该网络设备调度的该第一通信设备与该第二通信设备进行该侧行信息传输的第三资源，使得第一通信设备在接收到该第三指示信息后，便可在该第三资源上向该第二通信设备发送该侧行信息。由于该方法中，可通过第一通信设备向网络设备发送第二请求消息，使得网络设备调度该第一通信设备与该第二通信设备进行侧行信息传输的资源，避免了调度第二通信设备进行信息发送，可有效保证第一通信设备向第二通信设备所发送的侧行信息的可达性，有效解决了侧行链路上半双工问题所引起的信息不可达问题。

无论是网络设备还是该第一通信设备，均需维护逻辑信道组与组播组/第二通信设备的对应关系，用以根据LCG标识，继而确定第二通信设备；或者用以根据LCG标识，继而确定组播组，继而确定第二通信设备；或者，用以根据第二通信设备，确定LCG标识；或者，用以根据第二通信设备所属的组播组，确定LCG标识。
图7对应的示例中，可通过3个比特位最多指示8个LCG标识，这里不限制用3 比特指示，只是示例，还可以通过其它个数的比特进行指示。逻辑信道组与组播组/第二通信设备的对应关系可以与上述表2或表3类似，具体参照上述，在此不再赘述。
在第五示例中，图8为本申请实施例提供的一种信息传输方法中BSR消息中携带第二通信设备的标识信息的结构示意图五。如图8所示，BSR消息可包括1字节的LCG标识，以及m个字节的缓存大小。其中，1字节的LCG标识中，为第一通信设备的业务流对应的LCG标识的一个比特位的值，或者，第一通信设备所属的组播组的业务流对应的LCG标识的一个比特位的值。LCG 0-LCG 7，构成了该第一通信设备的业务流对应的LCG标识，或者，第一通信设备所属的组播组的业务流对应的LCG标识。其中，该第一通信设备的业务流为针对该第二通信设备传输的业务流，该第一通信设备和该第二通信设备属于同一组播组。
对于该第一通信设备的所有业务，或者，第一通信设备所属的组播组内的所有业务，具有同一个该LCG标识。
由于该第一通信设备的业务流为针对该第二通信设备传输的业务流，则该第一通信设备的业务流对应的LCG标识可用于指示该第二通信设备。该第一通信设备和该第二通信设备属于同一组播组，则该第一通信设备所属的组播组的业务流对应的LCG标识可指示该第二通信设备所在的组播组。
需要说明的是，上述图7或图8仅为LCG标识指示第二通信设备的一些示例，图7和图8中的LCG标识还可替换为第二通信设备的标识，或者第二通信设备的设备索引，或者，第二通信设备所属的组播组标志，或者第二通信设备所属的组播组的组播组索引，或者半静态调度配置索引。即，本申请可通过在BSR中携带第二通信设备的标识，或者第二通信设备的设备索引，或者第二通信设备所属的组播组标志，或者第二通信设备所属的组播组的组播组索引，或者，半静态调度配置索引，其对应的结构图可与上述图7或图8类似，在此不再赘述。
上述图4-图8仅为BSR的一些可能的示例，在实际应用中，BSR消息还可包括其它的信息，各部分信息所占的比特数和前后位置，可不限于上述图4-图8所示。
在第一示例中，该BSR消息还可包括：该第一通信设备的半静态调度配置索引，或者该第一通信设备所属的组播组的半静态调度配置索引。该第一通信设备的半静态调度配置索引为针对该第二通信设备传输的半静态调度配置索引。该第一通信设备所属的组播组的半静态调度配置索引为针对该组播组传输的半静态调度配置索引，该第一通信设备和该第二通信设备属于同一组播组。
该第一通信设备的不同半静态调度配置索引，可对应不同第二通信设备传输的不同单播调度请求；也可对应同一个通信设备传输的不同业务的不同单播调度请求；该第一通信设备所属的组播组的不同半静态调度配置索引，可对应不同组播组传输的不同组播调度请求；也可对应同一个组播组传输的不同业务的不同组播调度请求。因此，基于该BSR消息中的半静态调度配置索引可使得网络设备确定调度请求所针对的第二通信设备，或者，第二通信设备所属的组播组。
在第六示例中，图9为本申请实施例提供的一种信息传输方法中BSR消息中携带第二通信设备的标识信息的结构示意图六。如图9所示，BSR消息中，针对每个第二 通信设备，可包括：4比特的目的索引，2比特的LCG标识、6比特的缓存大小以及4比特的半静态调度配置索引。
图9中目的索引以及LCG标识的含义可以与上述图4中类似，具体参见上述，在此不再赘述。
该半静态调度配置索引可以为：该第一通信设备的半静态调度配置索引，或者该第一通信设备所属的组播组的半静态调度配置索引。该第一通信设备的半静态调度配置索引为针对该第二通信设备传输的半静态调度配置索引。该第一通信设备所属的组播组的半静态调度配置索引为针对该组播组传输的半静态调度配置索引，该第一通信设备和该第二通信设备属于同一组播组。
无论是网络设备还是该第一通信设备，均需维护半静态调度配置索引与组播组/第二通信设备的对应关系，用以根据半静态调度配置索引，继而确定第二通信设备；或者用以根据半静态调度配置索引，继而确定组播组，继而确定第二通信设备；或者，用以根据第二通信设备，确定半静态调度配置索引，或者，用以根据第二通信设备所属的组播组，确定半静态调度配置索引。
半静态调度配置索引与组播组/第二通信设备的对应关系例如可以为下述表4所示。
表4
半静态调度配置索引 组播组/第二通信设备
0000 V2X-G-RNTI 0
0001 C-RNTI 1
…… ……
1111 V2X-G-RNTI 15
根据表4可知，若半静态调度配置索引为0000，则其对应的组播组为V2X-G-RNTI0对应的组播组；若半静态调度配置索引为0001，则其所对应的第二通信设备为C-RNTI 1对应的通信设备；若半静态调度配置索引为1111，则其对应的组播组为V2X-G-RNT 15对应的组播组。
上述表4仅为半静态调度配置索引与组播组/第二通信设备的对应关系的一种可能的示例，半静态调度配置索引与组播组/第二通信设备的对应关系还可以为其它示例，在此不再赘述。
基于上述任一所述的信息传输方法，在一种可能的示例中，在该信息传输方法中，网络设备可通过显性指示的方式向第一通信设备指示本次调度所针对的第二通信设备。例如，该网络设备可通过在向第一通信设备发送的下行控制信息(Downlink Control Information，DCI)中增加预设的字段以携带该第二通信设备的标识信息，或者，通过该DCI中的可复用字段携带该第二通信设备的标识信息。
在另一种可能的示例中，该信息传输传输方法，网络设备还可通过隐性指示方式向第一通信设备指示本次调度所针对的第二通信设备。例如，该网络设备可依次通过第二通信设备和第一通信设备的标识信息对待发送的DCI进行加扰。当第一通信设备接收到消息后，便可反向依次通过第一通信设备和第二通信设备的标识信息进行解扰，继而得到对应的DCI。若解扰成功，第一通信设备便可确定该第二通信设备，继而实 现第二通信设备的隐性指示。
图10为本申请实施例提供的一种信息传输方法的流程图三。该图10所示的方法可在上述图2或3所示的方法的基础上执行。如图10所示，该方法可包括：
S1001、网络设备根据该第二通信设备的标识信息对DCI进行第一加扰。
该第二通信设备的标识信息可以为与上述BSR消息中所包括的第二通信设备的标识信息类似，在此不再赘述。
S1002、网络设备根据该第一通信设备的标识信息对该第一加扰后的DCI进行第二加扰。
该第一通信设备的标识信息可包括该第一通信设备的C-RNTI。当然，也可以为其它信息，在此不再赘述。

在该实施例的信息传输方法中，网络设备可根据该第二通信设备和该第一通信设备的标识信息对DCI进行二次加扰，既保证了DCI的准确传输，还实现了第二通信设备的标识信息的隐性指示。
S1004、第一通信设备接收来自网络设备发送的该第二加扰后的DCI。
S1005、第一通信设备根据该第一通信设备的标识信息对该第二加扰后的DCI进行第一解扰。
S1006、第一通信设备根据该第二通信设备的标识信息对该第一解扰后的信息进行第二解扰，若解扰成功，便可确定该第二通信设备。

如上任一所述的信息传输方法可适用于动态调度传输场景中，还可适用于半静态调度场景中。若适用于半静态调度传输场景，可先执行一段时间的动态调度传输，在持续一段时间后，可由网络设备触发并激活业务的半静态传输场景。
半静态传输之前进行的动态调度传输过程中，第一通信设备例如可将半静态调度配置索引携带在上述第二请求消息，如BSR消息中，发送至网络设备，以指示请求的调度所针对第二通信设备的单播或第二通信设备所属的组播组的组播；网络设备也可将该半静态调度配置索引携带在DCI返回至该第一通信设备，以指示第二通信设备的单播或者第二通信设备所属的组播组的组播。
网络设备可通过向第一通信设备发送无线资源控制(Radio Resource Control，RRC)，配置进行半静态调度传输。即该网络设备可向第一通信设备发送RRC消息，该RRC消息可包括：该半静态调度配置索引等信息。该半静态调度配置索引可以为该第一通信设备的半静态调度配置索引，或者，该第一通信设备所属的组播组的半静态调度配置索引。该第一通信设备的半静态调度配置索引为针对该第二通信设备传输的半静态调度配置索引。该第一通信设备所属的组播组的半静态调度配置索引为针对该第二通信所属的组播组的传输的半静态调度配置索引。该第一通信设备和该第二通信设备属于同一组播组。
对于网络设备和该第一通信设备，分别维护有半静态调度索引与通信设备或组播 组的对应关系。网络设备可根据该第二通信设备或第二通信设备所属的组播组以及该对应关系，确定该半静态调度索引，并将其携带在RRC中发送至该第一通信设备。该第一通信设备可在接收到该RRC消息后，根据其包括的半静态调度索引，以及该对应关系，确定该第二通信设备或者第二通信设备所属的组播组，继而触发半静态调度传输。
