图2是本申请实施例的侧行通信方法的示意性流程图。图2所示的方法可以由终端设备执行,图2所示的方法包括步骤110至步骤130,下面对步骤110至步骤130进行详细的介绍。
110、网络设备向终端设备发送资源配置信息,终端设备接收该资源配置信息。
上述资源配置信息可以用于为该终端设备配置公共资源,其中,该公共资源为网络设备为该网络设备覆盖范围内的所有终端设备配置的所有终端设备均需使用的用于侧行通信的资源。
也就是说,上述公共资源是网络设备为网络设备的覆盖范围内的所有终端设备配置的时频资源,网络设备覆盖范围内的所有终端设备均需要使用该公共资源用于侧行通信
120、网络设备向终端设备发送侧行链路BWP指示信息,终端设备接收该侧行链路BWP指示信息。
其中,该侧行链路BWP指示信息用于指示N个侧行链路带宽部分SL-BWP,该N个SL-BWP为终端设备进行侧行通信的带宽部分BWP,该N个SL-BWP包含公共资源对应的频域资源,N为正整数。
进一步的,上述侧行链路BWP指示信息还可以是网络设备发送的激活信息,该激活信息可以承载于无线资源控制(radio resource control,RRC)信令中,该激活信息用于激活N个SL-BWP,从而得到N个激活的SL-BWP,该N个激活的SL-BWP可以用于后续的侧行通信。
上述公共资源可以为公共资源池。
可选地,上述N个SL-BWP中包含公共资源对应的频域资源可以是指该N个SL-BWP中的至少一个SL-BWP包含公共资源对应的频域资源。
上述公共资源可以包含K个子公共资源,其中,K为大于1的正整数。
例如,网络设备通过资源配置信息为终端设备配置了公共资源,该公共资源包括3个子公共资源。假设侧行链路BWP指示信息指示了3个SL-BWP,那么,在该3个SL-BWP中,可以只有一个SL-BWP包含全部3个子公共资源对应的频域资源,也可以是3个SL-BWP中的2个SL-BEP包含全部3个子公共资源对应的频域资源,也可以是3个SL-BWP中的每个SL-BWP均包含1个子公共资源对应的频域资源。
130、终端设备在N个SL-BWP上与其它终端设备进行侧行通信。
如图2所示,上述其它终端设备可以包括终端设备1至终端设备i(i为正整数)等至少一个终端设备。也就是说,在图2所示的方法中,终端设备可以在N个SL-BWP上与其它的一个或者多个终端设备进行侧行通信。该侧行通信可以为终端设备向其它终端设备发送侧行控制信息和/或侧行数据,也可以为终端设备从其它终端设备接收侧行应答信息或侧行反馈信息。
本申请中,通过为终端设备配置N个SL-BWP,并且配置的该N个SL-BWP中包含公共资源对应的频域资源,使得终端设备能够在该N个SL-BWP上与其它终端设备进行侧行通信。
可选地,图2所示的方法还包括步骤140,应理解,步骤140可以在步骤110之后发生,下面对步骤140进行详细介绍。
140、网络设备向终端设备发送侧行链路BWP配置信息,终端设备接收该侧行链路BWP配置信息。
其中,上述侧行链路BWP配置信息用于为终端设备配置M个SL-BWP,该M个SL-BWP是可用于侧行通信的BWP,该N个SL-BWP属于M个SL-BWP,M为大于或者等于N的正整数。
上述N个SL-BWP可以是从配置的M个SL-BWP激活出来的SL-BWP,进一步的,上述N个SL-BWP可以是从M个SL-BWP激活出来的包括公共资源对应的频域资源的SL-BWP。
可选地,图2所示的方法还包括步骤150,应理解,步骤150可以先于步骤140发生,或者后于步骤140发生,或者,步骤150和步骤140可以同时发生。
本申请对步骤110至步骤150之间的先后顺序不做严格限定,只要这些步骤发生的先后顺序符合通信逻辑,能够正常进行侧行通信即可。下面对步骤150进行详细介绍。
150、网络设备向终端设备发送上行链路BWP指示信息,终端设备接收该上行链路BWP指示信息。
该上行链路BWP指示信息用于指示Y个上行链路带宽部分UL-BWP,Y为正整数。
在配置SL-BWP的同时,也可以为终端设备配置UL-BWP,使得终端设备能够根据UL-BWP与网络设备之间进行通信。
应理解,上述Y个UL-BWP与N个SL-BWP既可以位于同一载波,也可以位于不同的载波中,并且当Y个UL-BWP与N个SL-BWP位于同一载波时,N个SL-BWP还可以复用Y个UL-BWP的一部分资源。
下面结合图3至图5对SL-BWP与UL-BWP的在载波上的分布进行详细的介绍。应理解,图3至图5中所示的SL-BWP是指上述N个SL-BWP,图3至图5中所示的UL-BWP是指上述Y个UL-BWP,为了简洁,下面结合图3至图5对Y个UL-BWP与N个SL-BWP进行介绍时,以图3至图5中所示的UL-BWP表示上述Y个UL-BWP,以图3至图5中所示的SL-BWP表示上述N个SL-BWP。
如图3所示,SL-BWP与UL-BWP位于同一载波中(SL-BWP与UL-BWP位于共享载波中),并且SL-BWP占用的频域资源是UL-BWP占用的频域资源的子集。
通过将UL-BWP与SL-BWP配置到同一载波中,能够优化频谱资源的利用效率。
应理解,当UL-BWP和SL-BWP位于同一载波中时,UL-BWP占用的频域资源可以与SL-BWP占用的频域资源只有部分重复。
如图4所示,SL-BWP与UL-BWP位于同一载波中,但是SL-BWP与UL-BWP包含不同的频域资源。这种情况下,侧行通信和上行通信可以完全独立,相互之间不会产生干扰。
如图5所示,SL-BWP位于载波1中,UL-BWP位于载波2中。
通过将UL-BWP与SL-BWP配置到不同的载波中,能够在不同的载波上分别进行侧行通信以及终端设备与网络设备之间的上行通信,避免侧行通信与上行通信之间互相干扰。
可选地,作为一个实施例,上述资源配置信息携带有复用格式指示信息,所述复用格式指示信息用于指示所述终端设备采用所述公共资源进行侧行通信时发送的侧行数据和侧行控制信息的复用格式,所述复用格式包括频分复用和时分复用。
例如,对于超低时延需求的侧行业务,可以配置侧行数据和侧行控制信息在同一时隙(slot)采用时分复用,对于高可靠性需求的侧行业务,则可以配置侧行数据和侧行控制信息在同一时隙采用频分复用。
网络设备通过为公共资源配置复用格式,可以满足终端设备不同业务的侧行通信需求。网络设备可以根据业务类型等需求来灵活配置侧行资源,提高系统性能。
应理解,上述资源配置信息除了携带复用格式指示信息之外,还可以携带传输模式指示信息和参数集(numerology)指示信息,用于指示采用公共资源进行侧行通信时的传输模式以及参数集的情况。
可选地,资源配置信息携带有传输模式指示信息,该传输模式指示信息用于指示终端设备采用公共资源进行侧行通信时的传输模式,该传输模式包括单播传输(unicast),组播传输(groupcast)和广播传输(broadcast)。
网络设备能够根据侧行通信的不同需求来灵活配置侧行资源,能够提高侧行通信的效果,提高系统性能。
可选地,资源配置信息携带有参数集指示信息,该参数集指示信息用于指示终端设备采用公共资源进行侧行通信时的参数集(numerology),该参数集包括子载波间隔(subcarrier spacing,SCS)和循环前缀(cyclic prefix,CP)。
网络设备可以根据侧行通信的不同寻求来灵活配置参数集,进而实现灵活地额配置侧行资源,能够提高侧行通信的效果。
应理解,终端设备之间可以通过公共资源进行侧行通信,在某些情况下,有些终端设备对业务的可靠性要求比较高,或者对侧行通信的数据的保密性要求较高,那么,这种情况下,可以通过为某些终端设备单独配置专用资源,使得这些终端设备利用专用资源进行侧行通信。
因此,网络设备除了通过上述资源配置信息为终端设备配置公共资源之外,还可以通过资源配置信息为终端设备配置专用资源。
可选地,上述资源配置信息还用于为终端设备配置专用资源,该资源配置信息携带有复用格式指示信息,该复用格式指示信息用于指示终端设备采用该专用资源进行侧行通信时发送的侧行数据和侧行控制信息的复用格式,该复用格式包括频分复用和时分复用。
可选地,该资源配置信息还携带有传输模式指示信息,该传输模式指示信息用于指示终端设备采用专用资源进行侧行通信时的传输模式,该传输模式包括单播传输(unicast),组播传输(groupcast)和广播传输(broadcast)。
因此,网络设备能够根据侧行通信的不同需求来灵活配置侧行资源,能够提高侧行通信的效果,提高系统性能。
可选地,该资源配置信息还携带有参数集指示信息,该参数集指示信息用于指示终端设备采用专用资源进行侧行通信时的参数集(numerology),该参数集包括子载波间隔(subcarrier spacing,SCS)和循环前缀(cyclic prefix,CP)。
网络设备可以根据侧行通信的不同寻求来灵活配置参数集,进而实现灵活地额配置侧 行资源,能够提高侧行通信的效果。
上述专用资源具体可以为专用资源池。
网络设备可以根据侧行通信的特点和需求为某些终端设备配置专用资源,使得某些终端设备通过配置的专用资源进行侧行通信,能够提高系统性能。
可选地,当网络设备通过资源配置信息为终端设备配置了专用资源时,该资源配置信息还可以携带复用格式指示信息,该复用格式指示信息用于指示该终端设备采用该专用资源进行侧行通信时发送的侧行数据和侧行控制信息的复用格式,该复用格式包括频分复用和时分复用。
网络设备通过为专用资源配置复用格式,可以满足终端设备不同业务的侧行通信需求。
上文结合图2至图5对本申请实施例的侧行通信方法进行了详细的介绍,为了更好地理解本申请实施例的侧行通信方法,下面结合实例一(对应图6至图8)对终端设备1与终端设备2进行侧行通信的过程进行详细的介绍。
在实例一中,网络设备为终端设备配置包含公共资源的SL-BWP,该公共资源可以是公共资源池,使得终端设备可以通过该包含公共资源的SL-BWP的资源池进行侧行通信。
下面结合图6以公共资源为公共资源池为例,对实例一中终端设备1和终端设备2进行侧行通信的完整过程进行详细的介绍。
图6所示的方法包括步骤1001至步骤1007,下面对这些步骤进行详细介绍。
1001、网络设备为终端设备1配置资源池。
1002、网络设备为终端设备2配置资源池。
应理解,上述步骤1002既可以先于步骤1001进行也可以后于步骤1001进行,或者,步骤1002也可以与步骤1001同时进行。
在上述步骤1001和步骤1002中,网络设备可以通过系统消息块(system information block,SIB)、小区级(cell-specific)的RRC信令或者终端用户级(UE-specific)RRC信令为终端设备1和终端设备2配置资源信息。
该资源信息相当于上文中的资源配置信息,通过该资源信息能够为终端设备配置资源。具体地,该资源信息可以用于为终端设备配置资源池,此时该资源信息也可以成为资源池信息(资源池配置信息)。
上述资源信息指示了N个资源池,在该N个资源池中至少有M个公共资源池(Common Resource Pool)和(N-M)个专用资源池(Dedicated Resource Pool),N≥1,1≤M≤N。
如图7所示,网络设备为终端设备1和终端设备2配置了两个公共资源池,这两个公共资源池分别是公共资源池1(CommonResourcePool#1)和公共资源池2(CommonResourcePool#2)。
除了公共资源池之外,网络设备还为终端设备1和终端设备2配置了两个专用资源池,这两个专用资源池分别为专用资源池1(DedicatedResourcePool#1)和专用资源池2(DedicatedResourcePool#2)。
其中,公共资源池对于所有终端用户而言是公用的,所有终端用户都可以在公共资源池进行侧行通信,包括SL数据的发送和接收。一部分终端用户可以在专用资源池进行侧 行通信,这取决于网络设备的配置和终端用户自身的能力和需求。
1003、网络设备为终端设备1配置M个SL-BWP。
1004、网络设备为终端设备2配置M个SL-BWP。
在上述步骤1003和步骤1004中,网络设备可以通过RRC信令为终端设备配置SL-BWP。
1005、网络设备为终端设备1激活N个SL-BWP。
1006、网络设备为终端设备2激活N个SL-BWP。
在步骤1005和步骤1006中,网络设备可以通过向终端设备1和终端设备2发送激活信令来激活N个SL-BWP。
对于终端设备1来说,激活的N个SL-BWP包括公共资源池1和公共资源池2,也就包括全部的公共资源池,对于终端设备2来说,激活的N个SL-BWP也包括公共资源池1和公共资源池2。
以终端设备1为例,N个SL-BWP包括全部的公共资源池是指在这N个SL-BWP中,至少有一个SL-BWP包含全部的公共资源池。例如,如图7所示,在N个SL-BWP中,第一个SL-BWP和第N个SL-BWP均包含公共资源池1和公共资源池2。
应理解,对于终端设备1和终端设备2来说,它们包含的激活的SL-BWP的数量可以不同,只要激活的SL-BWP中至少有一个SL-BWP包含全部的公共资源池,终端设备1和终端设备2之间就可以进行侧行通信。
1007、终端设备1在激活的N个SL-BWP上的资源池中与终端设备2进行侧行通信。
应理解,图6所示的方法还可以包括步骤:
1008、网络设备为终端设备1配置X个BWP;
1009、网络设备为终端设备2配置X个BWP。
在步骤1008和步骤1009中,终端设备具体可以通过RRC信令为终端设备1和终端设备2配置BWP。
对于同一个终端设备来说,在同一时刻可以激活至少一个BWP用于通信传输。其中,用于下行通信的带宽中配置的BWP为DL-BWP,用于上行通信的带宽中配置的BWP为UL-BWP。
应理解,步骤1008和步骤1009中的配置BWP中的动作与步骤1003和步骤1004中配置SL-BWP中的动作既可以同时进行,也可以先后进行(配置BWP在前,配置SL-BWP在后,或者,配置SL-BWP在前,配置BWP在后)。
应理解,在实例一中,终端设备1或者终端设备2可以同时进行侧行通信和上行通信(Uu空口的通信),其中,侧行通信和上行通信可以发生在共享载波(shared carrier)上,也就是说SL-BWP与UL-BWP位于同一载波,如图3所示,SL-BWP可以在UL-BWP内部,复用UL-BWP的资源。另外,如图4所示,侧行通信和上行通信发生在共享载波(shared carrier)上,但SL-BWP和UL-BWP不重合,即SL和UL不使用相同的资源。
可选地,侧行通信和上行通信也发生在独立的载波(shared carrier)上,SL-BWP和UL-BWP不重合。即SL和UL不使用相同的资源。
在上述过程中,SL-BWP均是通过网络设备配置的,当没有网络设备控制时,SL-BWP也可以由终端设备自身进行配置。
在实例一中,终端设备不仅可以通过公共资源池中的时频资源与其它的终端设备进行侧行通信,终端设备还可以通过专用资源池中的时频资源与其它的终端设备进行侧行通信,与公共资源池不同,专用资源池一般是根据终端设备的能力或者需求,由网络设备配置或者用户根据预配置的资源或者侦听(sensing)来选择,为部分终端设备的SL-BWP配置的资源,下面结合图8对利用公共资源池和专用资源池中的资源进行侧行通信的过程进行详细的描述。
如图8所示,网络设备配置了2个公共资源池和3个专用资源池,分别为公共资源池1(CommonResourcePool#1)、公共资源池2(CommonResourcePool#2)以及专用资源池1(DedicatedResourcePool#1)、专用资源池2(DedicatedResourcePool#2)和专用资源池3(DedicatedResourcePool#3)。假设一个小区有4个终端,这4个终端分别为UE-A、UE-B、UE-C和UE-D,那么,网络设备通过RRC信令配置4个UE各自的SL-BWP,各个UE的SL-BWP分别为:
UE-A:UE-A SL-BWP#1、UE-A SL-BWP#2;
UE-B:UE-B SL-BWP#1;
UE-C:UE-C SL-BWP#1、UE-C SL-BWP#2;
UE-D:UE-D SL-BWP#1、UE-D SL-BWP#2、UE-D SL-BWP#3。
其中,每个UE中都有一个SL-BWP覆盖了公共资源池1和公共资源池2。
进一步的,专用资源池1和专用资源池2被UE-A SL-BWP#1和UE-D SL-BWP#1覆盖,UE-A和UE-D除了可以通过公共资源池1和公共资源池2中的时频资源进行侧行通信之外,还可以通过专用资源池1或者专用资源池2中的时频资源进行侧行通信。
另外,专用资源池3被UE-C SL-BWP#2和UE-D SL-BWP#3覆盖,因此,UE-C和UE-D除了可以通过公共资源池1和公共资源池2进行侧行通信之外,还可以通过专用资源池3进行侧行通信。
另外,在实例一中,网络设备在配置资源池时,配置信息中还可以包括下列信息中的至少一种。
(1)侧行控制信息(sidelink scheduling assignment,SA)和侧行数据的复用格式指示信息。
侧行控制信息和侧行数据的复用格式可以采用复用格式指示信息中的一个比特位的比特值来表示,例如,当该比特位的取值为1时表示侧行控制信息和侧行数据是时分复用的,当该比特位的取值为0时表示侧行控制信息和侧行数据是频频分复用的。
(2)侧行通信时的传输模式,所述传输模式为单播传输,组播传输和广播传输。侧行通信时的传输模式可以使用2个比特位的比特值来表示,例如00表示单播,01表示组播,10表示广播。
(3)子载波间隔指示信息。
在载波间隔指示信息可以包含3个比特信息,至少指示15kHz,30kHz,60kHz,120kHz和240kHz这几种子载波间隔。
(4)循环前缀(cyclic prefix,CP)指示信息。
CP指示信息可以包含1个比特信息,当该比特位的取值为1时表示常规循环前缀(normal cyclic prefix,NCP),当该比特位的取值为0时表示扩展循环前缀(extended cyclic prefix,ECP)。

上文结合图11对本申请实施例的侧行通信方法进行了详细的介绍,为了更好地理解本申请实施例的侧行通信方法,下面结合实例二(对应图12至图14)对终端设备1与终端设备2进行侧行通信的过程进行详细的介绍。
在实例二中,网络设备为终端设备配置包含公共资源(该公共资源可以是公共资源池)的UL-BWP,使得终端设备可以通过复用该UL-BWP的资源池进行侧行通信。下面结合图12对实例二中终端设备1和终端设备2进行侧行通信的完整过程进行详细的介绍。
下面结合图12以公共资源为公共资源池为例,对实例二中终端设备1和终端设备2进行侧行通信的完整过程进行详细的介绍。
图12所示的方法包括步骤2001至步骤2006,下面对这些步骤进行详细介绍。
2001、网络设备为终端设备1配置资源池。
2002、网络设备为终端设备2配置资源池。
应理解,上述步骤2002既可以先于步骤2001进行也可以后于步骤2001进行,或者,步骤2002与步骤2001同时进行。
在上述步骤2001和步骤2002中,网络设备可以通过SIB、小区级的RRC信令或者终端用户级的RRC信令为终端设备1和终端设备2配置资源池信息。
其中,上述资源池信息指示了N个资源池,在该N个资源池中至少有M个公共资源池和N-M个专用资源池,N≥1,1≤M≤N。
例如,如图13所示,网络设备配置了2个公共资源池和2个专用资源池,分别为公共资源池1(CommonResourcePool#1)、公共资源池2(CommonResourcePool#2)以及专用资源池1(DedicatedResourcePool#1)和专用资源池2(DedicatedResourcePool#2)。
2003、网络设备为终端设备1配置X个UL-BWP。
2004、网络设备为终端设备2配置X个UL-BWP。

对于终端设备1来说,激活的Y个UL-BWP包括公共资源池1和公共资源池2,也就包括全部的公共资源池,对于终端设备2来说,激活的Y个UL-BWP也包括公共资源池1和公共资源池2。
以终端设备1为例,N个UL-BWP包括全部的公共资源池是指在这N个UL-BWP中,至少有一个UL-BWP包含全部的公共资源池。
应理解,对于终端设备1和终端设备2来说,它们包含的激活的UL-BWP的数量可以不同,只要激活的UL-BWP中至少有一个UL-BWP包含全部的公共资源池,终端设备1和终端设备2之间就可以进行侧行通信。
2007、终端设备1在激活的UL-BWP上与终端设备2进行侧行通信。
在实例二中,终端设备不仅可以通过公共资源池中的时频资源与其它的终端设备进行侧行通信,终端设备还可以通过专用资源池中的时频资源与其它的终端设备进行侧行通信,与公共资源池不同,专用资源池一般是根据终端设备的能力或者需求,由网络设备配置或者用户根据预配置的资源或者侦听(sensing)来选择,为部分终端设备的UL-BWP配置的资源,下面结合图14对利用公共资源池和专用资源池中的资源进行侧行通信的过程进行详细的描述。

假设一个小区有4个终端用户,分别为UE-A、UE-B、UE-C和UE-D,网络设备通过RRC信令配置4个UE各自的UL-BWP,各个UE的UL-BWP分别为:
UE-A:UE-A UL-BWP;
UE-B:UE-B UL-BWP;
UE-C:UE-C UL-BWP;
UE-D:UE-D UL-BWP。
其中,每个UE的UL-BWP都覆盖了公共资源池1和公共资源池2。
进一步的,UE-B UL-BWP只覆盖了公共资源池1和公共资源池2,因此,UE-B只能通过公共资源池1和公共资源池2中的时频资源进行侧行通信。UE-C UL-BWP除了覆盖公共资源池1和公共资源池2之外,还覆盖了专用资源池2,UE-A UL-BWP除了覆盖公共资源池1和公共资源池2之外,还覆盖了专用资源池1,UE-D UL-BWP则是覆盖了全部的公共资源池和全部的专用资源池。因此,UE-D可以除了可以通过专用资源池1和专用资源池2中的时频资源与其它三个UE进行侧行通信之外,UE-D还可以通过专用资源池1中的资源与UE-A通信,UE-D还可以通过专用资源池2中的时频资源与UE-C通信。
另外,在实例二中,网络设备在配置资源池时,配置信息中还可以包括下列信息中的至少一种。
(1)侧行控制信息(SA)和侧行数据的复用格式指示信息;
(2)侧行通信时的传输模式;
(2)子载波间隔(subcarrierspacing,SCS)指示信息;

图17是本申请实施例的侧行通信方法的示意性流程图。图17所示的方法可以由终端设备执行,图17所示的方法包括步骤310和步骤320,下面对步骤310和步骤320进行详细的介绍。
310、网络设备发送侧行链路BWP指示信息,终端设备接收该侧行链路BWP指示信息。
上述侧行链路BWP指示信息用于指示N个侧行链路带宽部分SL-BWP,N个SL-BWP为终端设备进行侧行通信的带宽部分BWP,N个SL-BWP包含公共SL-BWP,公共SL-BWP为网络设备为网络设备覆盖范围的所有终端设备配置的所有终端设备均需使用的用于侧行通信的频域资源。
320、终端设备在N个SL-BWP上与其它终端设备进行侧行通信。
如图17所示,上述其它终端设备可以包括终端设备1至终端设备i(i为正整数)等至少一个终端设备。也就是说,在图17所示的方法中,终端设备可以在N个SL-BWP上与其它的一个或者多个终端设备进行通信。

当SL-BWP与UL-BWP包含相同的频域资源时,SL-BWP可以复用UL-BWP的部分资源进行侧行通信,能够优化频谱资源的利用效率。
可选地,Y个UL-BWP与N个SL-BWP不包含相同的频域资源。
通过为UL-BWP和SL-BWP配置不同的频域资源,能够使得侧行通信和上行通信之间相互独立,相互之间不产生干扰。

通过将UL-BWP与SL-BWP配置到不同的载波中,能够在不同的载波上分别进行侧行通信以及上行通信,避免侧行通信与上行通信之间互相产生干扰。
网络设备通过配置复用格式,可以满足终端设备不同业务的侧行通信需求。
例如,对于超低时延需求的侧行业务,可以配置侧行数据和侧行控制信息在同一时隙(slot)采用时分复用,对于高可靠性需求的侧行业务,则可以配置侧行数据和侧行控制信息在同一时隙采用频分复用。

例如,对于超低时延需求的侧行业务,可以配置侧行数据和侧行控制信息在同一时隙(slot)采用时分复用,对于高可靠性需求的侧行业务,则可以配置侧行数据和侧行控制信息在同一时隙采用频分复用。

网络设备可以根据侧行通信的不同寻求来灵活配置参数集,进而实现灵活地额配置侧行资源,能够提高侧行通信的效果。
上文结合图17对本申请实施例的侧行通信方法进行了详细的介绍,为了更好地理解本申请实施例的侧行通信方法,下面结合实例三(对应图18)对终端设备1与终端设备2进行侧行通信的过程进行详细的介绍。
在实例三中,网络设备不再配置资源池,而是直接为多个终端设备配置SL-BWP,并且配置的SL-BWP中包含公共BWP,该公共SL-BWP为网络设备为网络设备覆盖范围的所有终端设备配置的所有终端设备均需使用的用于侧行通信的频域资源。
下面以终端设备1和终端设备2为例并结合图18对实例三中终端设备1和终端设备2进行侧行通信的完整过程进行详细的介绍。
图18所示的方法包括步骤3001至步骤3007,下面对这些步骤进行详细介绍。
3001、网络设备为终端设备1配置M个SL-BWP。
3002、网络设备为终端设备2配置M个SL-BWP。
在上述步骤3001和步骤3002中,网络设备可以通过RRC信令为终端设备配置SL-BWP。
3003、网络设备为终端设备1激活N个SL-BWP。
3004、网络设备为终端设备2激活N个SL-BWP。
在步骤3003和步骤3004中,网络设备可以通过向终端设备1和终端设备2发送激活信令来激活N个SL-BWP。
对于终端设备1来说,激活的N个SL-BWP包括公共BWP,该公共SL-BWP为网络设备为网络设备覆盖范围的所有终端设备配置的所有终端设备均需使用的用于侧行通信的频域资源。
应理解,上述公共SL-BWP的数量可以是一个或者多个。
同样,对于终端设备2来说,激活的N个SL-BWP也包括公共BWP。
3005、终端设备1在激活的N个SL-BWP上的资源池中与终端设备2进行侧行通信。
应理解,图18所示的方法还可以包括以下步骤:
3006、网络设备为终端设备1配置X个BWP;
3007、网络设备为终端设备2配置X个BWP。
在步骤3006和步骤3007中,终端设备具体可以通过RRC信令为终端设备1和终端设备2配置BWP。对于同一个终端设备来说,在同一时刻可以激活至少一个BWP用于通信传输。其中,用于下行通信的带宽中配置的BWP为DL-BWP,用于上行通信的带宽中配置的BWP为UL-BWP。
应理解,步骤3006和步骤3007中的配置BWP中的动作与步骤3001和步骤3002中配置SL-BWP中的动作既可以同时进行,也可以先后进行(配置BWP在前,配置SL-BWP在后,或者,配置SL-BWP在前,配置BWP在后)。
应理解,在实例三中,终端设备1或者终端设备2可以同时进行侧行通信和上行通信,其中,侧行通信和上行通信可以发生在共享载波(shared carrier)上,也就是说SL-BWP 与UL-BWP位于同一载波内。当SL-BWP与UL-BWP位于同一载波内时,SL-BWP可以与L-BWP包含相同的频域资源,进一步的,SL-BWP可以完全位于UL-BWP内部,也就是说,SL-BWP可以完全复用UL-BWP的频域资源。
另外,当SL-BWP与UL-BWP位于同一载波内时,SL-BWP的频域资源也可以与UL-BWP的频域资源没有交集。
可选地,侧行通信和上行通信也发生在独立的载波(shared carrier)上,SL-BWP和UL-BWP不重合。即SL和UL不使用相同的资源。
另外,在实例三中,网络设备在配置资源池时,配置信息中还可以包括下列信息中的至少一种。
(1)侧行控制信息(SA)和侧行数据的复用格式指示信息;
(2)侧行通信时的传输模式;
(2)子载波间隔(subcarrierspacing,SCS)指示信息;
(3)循环前缀(cyclic prefix,CP)指示信息。
上述指示信息的具体指示方式可参见实例一中相关内容,这里不再重复描述。
