以下通过具体实例详细描述本公开实施例中方法。
实例1:
例如,如图2所示,Relay2(即第一通信节点)即要与gNB/Relay1(即第二通信节点)进行Backhaul链路的通信,又需要与Relay3进行Access链路的通信,Backhaul链路的调度权由gNB/Relay1控制,Acess链路的调度权由Relay2控制。gNB/Relay1和Relay2之间的B-D链路构成Backhaul链路,Relay2和UE/Relay3之间的A-U链路构成Access链路,当然Backhaul链路和Access链路也可以称为第一链路和第二链路,或者其他的示例名称;gNB和核心网之间有光纤连接,Relay1和核心网之间没有光纤连接,Relay1只能通过一跳或者多跳无线Backhaul连接到一个gNB。为了描述简洁,本公开实施例中的通信链路可以简称为链路,时域频域资源可以简称为时频资源。
为了使得Relay2能够处理两个链路上的信号,需要协同两个链路上的信道或者信号占有的资源。两个链路上的复用方式存在表1所示的复用场景。在表1中TDM(Time division multiplex)表示时分复用,FDM(Frenquency division multiplex)表示频分复用,SDM表示(Spatial division multiplex)空分复用,TDD(Time division duplexing)表示时分双工,FDD(Frenquecy division duplexing)表示频分双工。
表1
其中,TDM的两个链路需要协商时域资源,FDM的两个链路需要协商频域资源,SDM的两个链路需要协商空域资源以及码域资源,参考信号资源等。下面以A-U和B-D之间的链路协商为例,上述资源的协商的方式包括如下两种方式:
方式一:
基于该方式的资源分配方法包括:
步骤11、Relay2给gNB/Relay1发送资源请求信息。
本实例中,可选地,所述第一通信节点和第二通信节点之间的信道或信号可占有的资源信息包括以下至少一种信息:
在所述资源上,所述第一通信节点不能接收所述第二通信节点发送的信道和/或信号;其中,所述资源为可占用的资源;
在所述资源上,所述第一通信节点不能向所述第二通信节点发送信道和/或信号;
在所述资源之外,所述第一通信节点可以接收所述第二通信节点发送的信道或信号;以及
在所述资源之外,所述第一通信节点可以向所述第二通信节点发送信道或信号;
所述第一通信节点和一个或多个第三通信节点之间的信号或信道可占有的资源信息包括以下至少一种信息:
在所述资源上,所述第一通信节点接收所述一个或者多个第三通信节点发送的信道或 信号;
在所述资源上,所述第一通信节点向所述一个或者多个第三通信节点发送信道或信号;
在所述资源之外,所述第一通信节点不能接收所述一个或者多个第三通信节点发送的信道和/或信号;以及
在所述资源之外,所述第一通信节点不能向所述一个或者多个第三通信节点发送的信道和/或信号。
本实例中,可选地,所述第一通信节点和第二通信节点之间信道或信号可占有的资源信息包括以下至少一种信息:
在所述资源上,第一通信节点可以接收第二通信节点发送的信道或信号;
在所述资源上,第一通信节点可以向所述第二通信节点发送信道或信号;
在所述资源之外,第一通信节点不接收第二通信节点发送的信道和/或信号;
在所述资源之外,第一通信节点不向所述第二通信节点发送信道和/或信号;
所述第一通信节点和一个或多个第三通信节点之间的信号或信道可占有的资源信息包括以下至少一种信息:
在所述资源上,第一通信节点不能接收所述一个或者多个第三通信节点发送的信道和/或信号;
在所述资源上,第一通信节点不能向所述一个或者多个第三通信节点发送信道和/或信号;
在所述资源之外,第一通信节点能接收所述一个或者多个第三通信节点发送的信道或信号;以及
在所述资源之外,第一通信节点能向所述一个或者多个第三通信节点发送信道或信号。
也就是说,资源请求信息用于指示如下至少之一信息:A-U链路占有的解调参考信号资源;B-D链路不可以占有的解调参考信号资源;B-D链路只能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源;A-U不能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源;或者
资源请求信息用于指示如下至少之一信息:B-D链路可以占有的解调参考信号资源;A-U链路不可以占有的解调参考信号资源;B-D链路不可以占有所述资源请求信息之外的解调参考信号资源;A-U链路可以占有所述资源请求信息中包括的解调信号资源之外的解调参考资源。
步骤12、gNB/Relay1根据Relay2发送的资源请求信息,并结合gNB/Relay1覆盖下的UE/Relay2的业务情况,给Relay2发送第一资源分配信息。
步骤13、Relay2接收第一资源分配信息,根据第一资源分配信息与gNB/Relay2之间通信,可选地根据所述第一资源分配信息向其覆盖下的Relay3/UE发送第二资源分配信息,用于调度/分配Relay2和Relay2覆盖下的Relay3/UE之间的信道或者信号占有的资源。
方式二:
基于该方式的资源分配方法包括:
步骤21、gNB/Relay1直接给Relay2发送第一资源分配信息。
步骤22,Relay2接收第一资源分配信息,根据第一资源分配信息与gNB/Relay2之间通信,可选地根据所述第一资源分配信息调度/分配Relay2和Relay2覆盖下的Relay3和UE之间的信号占有的资源。
在方式一和方式二中,gNB/Relay1给Relay2发送的第一资源分配信息,用于指示如下至少之一信息:A-U链路占有的解调参考信号资源;B-D链路不可以占有的解调参考信号资源;B-D只能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源;A-U不能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源;或者
资源分配信息用于指示如下信息至少之一:B-D可以占有的解调参考信号资源;A-U链路不可以占有的解调参考信号资源;B-D不可以占有所述资源请求信息之外的解调参考信号资源;A-U可以占有所述资源请求信息中包括的解调信号资源之外的解调参考资源。
其中所述资源包括如下资源至少之一:参考信号资源、时域资源、频域资源、空域资源、码域资源、控制信道资源。
其中所述参考信号包括如下参考信号至少之一:解调参考信号、相位跟踪参考信号、测量参考信号。
在本公开实施例中,资源分配也可以描述为资源协调。上述两种方式是以A-U和B-D两个链路之间的资源协调为例,类似地可以用于A-D和B-U两个链路之间的资源协调,也可以用于A-D和B-D两个链路之间的资源协调,也可以用于A-U和B-U两个链路之间的资源协调,或者用于A链路和B链路之间的资源协调,其中A链路包括A-D和B-U,B链路包括B-U和A-D。
当两个链路采用频分复用时,需要协商两个链路占有的频域资源,其中不同链路可以占有不同的载波成员CC(Component Carrior),或者不同的链路占有一个CC下的不同的带宽部分BWP(Bandwidth part),或者不同的链路占有一个BWP下的不同的物理资源块PRB(Physical Resource Block)集合。也即上述频域资源请求信息中和/或第一频域资源分配信息中包括如下信息至少之一:CC、BWP、BWP中的PRB集合。当为BWP/PRB集合时,需要gNB/Realy1和Realy2约定,Backhaul链路和Access链路占有的频域资源之间没有重叠。
可选地,所述第一资源分配信息包括在高层信令中,比如第一资源分配信息中分配了B-U可占的资源,通过物理层控制信道和/或高层信令,分配B-U中的信道或者信号在高层信令分配的可占有的资源中实际占有的资源。
当两个链路采用空分复用的时候,可以协调两个链路占有的码域资源,比如信道的加扰序列资源,使得两者的加扰序列不同,比如Relay2向gNB/Relay1发送资源请求信息,和/或gNB/Relay1向Relay2发送第一资源分配信息,其中资源请求信息和/或第一资源分 配信息中包括加扰序列的产生参数,如标准38.211中PUSCH(Physical uplink shared channel上行共享信道)信道的信息加扰序列产生参数如公式(1-1)所示的n
ID和/或n
RNTI,PDSCH的序列的加扰序列的产生参数为公式(1-2)所示的n
ID和/或n
RNTI。特别是两个链路上的传输广播消息或者组消息的PDSCH的加扰序列的产生参数两者需要协商。

init=n

实例2:
当两个链路之间采用空分复用,表示这两个链路之间占有的时频资源之间有重叠,或者这两个链路可以在相同的时频资源集合中独立调度,采用不用的波束区分。两个链路采用空分复用时,需要考虑参考信号和/或控制信道之间的两个链路的干扰问题,即两个链路上参考信号之间的复用方式是其他信道或者信号的复用方式的子集,和/或两个链路上控制信道之间的复用方式是其他信道或者信号的复用方式的子集,其中其他信道或者信号是除了参考信号和/或控制信道资源之外的其他信道或信号。
比如两个链路的数据信道可以空分复用,但是由于测量和实际传输阶段的信道之间的差异,以及旁瓣的干扰,需要保证两个链路解调参考信号之间的正交,从而在两个链路的数据信道占有的时频资源重叠的基础上,可以保证两个链路的性能。
本实例中,两个链路的组合包括如下组合至少之一:B-D与A-D、B-D与A-U、B-D与A-U、B-U与A-D、B链路和A链路,其中A链路包括A-D和B-U,B链路包括B-U和A-D。
在讲述解调参考信号资源信息之前,首先讲述一下NR中的解调参考信号图样。
NR中PDSCH(Physical Downlink Shared Channel,物理下行共享信道)的解调参考信号,或者当transforming precoding传输预编码不使能时,PUSCH的解调参考信号图样存在Configuration type(配置类型)1和Configuration type2,以下以PDSCH为例,DMRS(Demodulation Reference Signal,解调参考信号)的图样如公式(1)所示:
其中
表示DMRS相对PDSCH的功率差,w
f(k')是端口频域正交化向量中的元素,w
t(l')是端口的时域正交化向量中的元素,当DMRS的图样类型Configuration type1时,Δ为频域梳索引,如图3所示,一个DMRS端口占有一个频域梳中的所有RE且只在一个频域梳中,一个频域梳中的不同端口可以通过码分复用的方式复用,所以一个频域梳 也可以称为一个CDM(code divisivion multiplex,码分复用)组,当为Configuration type2时,Δ为频域组索引,一个DMRS端口占有一个频域组中的所有RE且只在一个频域组中,一个频域组中的不同端口通过码分复用方式复用,所以一个频域组也可以称为一个CDM组,端口号和w
f(k'),w

t(l'),Δ之间的对应关系参照在Configuration type2的时候,如表3所示。

是DMRS占有的一组连续时域符号中的起始时域符号索引,当DMRS占有的一组连续的时域符号中只有一个时域符号时,
根据表4获取;当DMRS占有的一组连续的时域符号中有2个时域符号时,
根据表5获取。l'用于指示DMRS占有的一组连续时域符号中的局部索引。r(2n+k')根据公式(2)获取:

表6:
以上是以PDSCH的解调参考信号为例,PUSCH(物理上行共享信道,Physical Uplink Shared Channel)在tranforming precoding不使能时,即PUSCH采用CP-OFDM(循环前缀-正交频分复用技术,Cyclic Prefix-Orthogonal Frequency Division Multiplexing)传输,PUSCH的解调参考信号的图样和PDSCH的解调参考信号的图样相同,此处不再赘述。
当PUSCH的transforming precoding使能时,即PUSCH采用SC-FDMA(单载波频分多址,Single-carrier Frequency-Division Multiple Access)方式传输时,PUSCH的解调参考信号采用configuration type1的图样,而且r(2n+k')采用ZC序列。
下面以B-D和A-U两个链路的解调参考信号之间的协调为例,讲述两个链路之间的解调参考信号的资源分配方法,类似地可以用于上述其他的两个链路的资源分配。本实例也包括两种方式。
方式一
步骤31,Relay2给gNB/Relay1发送资源请求信息,所述资源请求信息用于请求第一信息。
步骤32,gNB/Relay1根据Relay2发送的资源请求信息,并结合gNB/Relay1覆盖下的UE/Relay2的业务情况,给Relay2发送第一资源分配信息。
步骤33,Relay2接收第一资源分配信息,根据第一资源分配信息与gNB/Relay2之间通信,可选地地根据所述第一资源分配信息向其覆盖下的Relay3/UE发送第二资源分配信 息,用于调度/分配Relay2和Relay2覆盖下的Relay3/UE之间的信道或者信号占有的资源。
方式二
步骤41,gNB/Relay1直接给Relay2发送第一资源分配信息。
步骤42,Relay2接收第一资源分配信息,根据第一资源分配信息与gNB/Relay2之间通信,可选地根据所述第一资源分配信息向其覆盖下的Relay3/UE发送第二资源分配信息,用于调度/分配Relay2和Relay2覆盖下的Relay3/UE之间的信道或者信号占有的资源。
在方式一和方式二中,gNB/Relay1给Relay2发送的第一资源分配信息,用于指示第二信息。
其中第一信息用于请求如下信息至少之一和/或第二信息用于指示如下信息至少之一:A-U可占有的解调参考信号资源;B-D的解调参考信号不能占有的解调参考信号资源;B-D的信道或信号不能占有所述A-U可占有的解调参考信号占有的时频资源;B-D的解调参考信号只能占有所述资源请求信息中包括的解调参考信号之外的参考信号;B-D的信道或信号只能占有所述资源请求信息中包括的解调参考信号资源占有的时频资源之外的时频资源;A-U的解调参考信号不能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源。
或者第一信息用于请求如下信息至少之一,和/或第二信息用于指示如下信息至少之一:B-D可占有的解调参考信号资源;A-U的解调参考信号不能占有的解调参考信号资源;A-U的信道或信号不能占有所述B-D可占有的解调参考信号占有的时频资源;A-U的解调参考信号只能占有所述资源请求信息中包括的解调参考信号之外的参考信号;A-U的信道或信号只能占有所述资源请求信息中包括的解调参考信号资源占有的时频资源之外的时频资源;B-D的解调参考信号不能占有所述资源请求信息中包括的解调参考信号资源之外的解调参考信号资源。
第一信息和/或第二信息可以包括的上述多个信息,一种方式是在第一信息和/或第二信息包括上述述多个信息的每个信息的配置值,另一种方式是在第一信息和/或第二信息包括上述多个信息中的有限个数个信息的配置值,其他信息根据配置值可以根据配置的信息得到,或者说一个配置值对应了上述多个信息。
例如,在上述资源请求信息中或者第一资源分配信息中如下信息至少之一:
信息一:解调参考信号图样类型dmrs-Type此信息用于指示DMRS的图样类型是公式(1)中的configuration type1还是configuration type2,即DMRS图样是图3中的图样还是图4的图样。
信息二:解调参考信号占有的除去第一连续时域符号组之外的连续时域符号组的个数dmrs-AdditionalPosition,即表4或者表5中的DL-DMRS-add-pos,用于指示DMRS占有的除去第一连续时域符号组之外的其他连续时域符号组的个数,因为第一连续时域符号组总是存在的。
信息三:解调参考信号占有的一个连续时域符号组中包括的时域符号个数的最大值 maxLength,用于指示DMRS占有的一个连续时域符号组中包括的时域符号个数的最大值,当maxLength为1时,DMRS的图样公式(1)中的
根据表4获取,当maxLength为2时,DCI(Down link control information)中可选指示DMRS占有的一个连续时域符号组中包括的时域符号个数是1还是2,是1时DMRS的图样公式(1)中的
根据表4获取,是2时DMRS的图样公式(1)中的
根据表5获取。
信息五:DMRS的起始时域符号位置,即解调参考信号的起始时域符号位置,即表4或者表5中的l
0。
信息六:DMRS占有的一个连续时域符号组中包括的时域符号个数,即DMRS的图样公式(1)中的
根据表4获取,还是根据表5获取。例如DMRS占有的一个连续时域符号组中包括的时域符号个数为1时,
根据表4,DMRS占有的一个连续时域符号组中包括的时域符号个数为2时,
根据表5获取。在NR中基站不会通过高层信令给UE配置这个参数,而是配置maxLength,maxLength为1时,
根据表4,maxLength为2时,可选根据动态信令信息DCI得到
是根据表4获取还是
根据表5获取,即动态信令告知DMRS占有的连续时域符号组中包括的时域符号个数是1还是2。但是在Relay端两个链路空分复用时,为了保证两个链路的解调参考信号的正交性,通过高层信令或者约定规则固定两个链路中的DMRS所采用的一个连续时域符号组中包括的时域符号个数要么为1要么为2,不能动态变化,这样在B-D和A-U之间SDM复用的时候避免B-D的数据和A-U的解调参考信号之间的干扰,或者B-D的解调参考信号和A-U的数据之间的干扰。
信息七:A-U中的PUSCH的transform precoding是否使能,即解调参考信号对应的信道的传输预编码是否使能,从而gNB/Relay1可以确定Backhaul链路上是否可以和A-U通过共享DMRS端口号,或者共享CDM组。
信息八:解调参考信号端口信息,即表4中的端口{1000~1007}中的端口子集信息,或者表5中的{1000~1011}中的端口子集信息,从而使得B-D和A-U采用不同的端口集合。比如gNB/Relay1通知B-U链路上的PUSCH/PUCCH占有的端口为图样类型1中的端口{1000,1001,1004,1005},则Relay2在A-D链路上调度的下行信号不要占用{1000,1001,1004,1005}占有的RE。
信息九:解调参考信号所在的频域组,即公式(1)中的Δ信息。从而B-U和A-D采用SDM复用的时候,他们的解调参考信号可以通过频分复用的方式复用,从而B-U可以采用PN序列,A-D可以采用ZC序列。
信息十:时域资源映射方式是mapping typeA还是mapping typeB,即解调参考信号对应的时域资源映射方式,通过高层信令或者约定规则固定其中之一,不要在mapping typeA和mapping typeB中动态变化。
信息十一:信道占有的时域符号个数Duration in symbols属于的时域符号的范围,从 上面可以看到,即使协调了两个链路上的解调参考信号中的上述信息一~信息十,还是无法保证两个链路中的解调参考信号之间的正交性,因为Duration in symbols动态变化之后,DMRS所在的时域符号会变化。为此需要约束信道占有的时域符号的动态变化范围。比如按表4所示,时域变化范围有如下5个范围1~2,3~9,10~11,12,13~14,或者表5中时域变化范围有3个4~9,10~12,13~14,或者根据如下配置信息:时域资源映射方式mapping type,解调参考信号占有的除第一个连续时域符号组之外的其他连续时域符号组的个数DL-DMRS-add-pos,解调参考信号占有的一个连续时域符号组中包括的时域符号个数是1single-symbol还是2double-symbol得到多个时域范围(即时域符号个数集合),比如当为single-symbol、mapping typeA、DL-DMRS-add-pos=0,则时域符号的变化范围为{3~14},当为single-symbol、mapping typeA、DL-DMRS-add-pos=1时,则时域范围包括{3~7}、{8~9}、{10~12}、{13~14},gNB/Relay1和Relay2约定,Backhaul上的时域资源列表中包括的时域符号个数只能属于上述一个约定的时域符号个数集合,而不能属于多个时域符号个数集合,从而根据解调参考信号的配置信息所述时域资源列表中包括的所有时域资源对应的解调参考信号的时域位置相同。也即解调参考信号占有的时域符号位置不动态变化。
信息十二:解调参考信号占有的时域符号集合,比如gNB/Relay1告知Relay2在Backhaul链路上解调参考信号占有的时域符号集合,B-D链路的解调参考信号不占有所述时域符号集合之外的时域符号。
信息十三:解调参考信号占有连续时域符号组的个数,即为dmrs-AdditionalPosition+1,即DMRS占有的连续时域符号组的个数,从而允许DMRS不用总是占有第一连续时域符号组。
也就是说,本公开实施例中,可选地,所述第一信息和/或所述第二信息包括解调参考信号的以下至少一种信息:
解调参考信号图样类型、解调参考信号占有连续时域符号组的个数、解调参考信号占有的一个连续时域符号组中包括的时域符号个数的最大值、产生解调参考信号序列的产生参数、解调参考信号的起始时域符号位置、解调参考信号对应的时域资源映射方式、解调参考信号占有的一个连续时域符号组中包括的时域符号个数、解调参考信号对应的信道的传输预编码是否使能、解调参考信号端口信息、解调参考信号端口所在的频域组、解调参考信号占有的时域符号集合、解调参考信号占有的除第一个连续时域符号组之外的其他连续时域符号组的个数、解调参考信号可占有的时域符号范围。
可选地,为了使得两个链路的DMRS达到正交,且希望两个链路的DMRS可以在一个CDM组时,就需要B-D可以采用ZC序列,因为B-U的解调参考信号可以用ZC序列,ZC序列也可以称为Low-PAPR序列,对于该序列可以参考3GPP标准协议38.211v15.0.0版本。可选地,可选限定B-D只有在解调参考信号图样类型限制为Configuration1的时候,才可以采用ZC序列,可选地需要信令通知下行解调参考信号的序列是PN序列还是ZC序列。PN序列是一种随机序列,即3GPP标准协议38.211v15.0.0中的Pseudo-random 序列。
两个链路SDM的时候,为了保证他们的DMRS正交,或者起码保证一个链路的数据不对另一个链路的数据构成干扰,可以gNB/Relay1通知B-D链路上的PDSCH的解调参考信号可占有的时域符号范围,即B-D链路上的PDSCH的解调参考信号占有的时域符号只能在所述可占有的时域符号范围内,可选地Relay2调度Relay3/UE在A-U上发送的信道或信号不要占有DMRS可占有的时域符号范围内。
上述是分配两个链路的解调参考信号资源,类似地两个链路SDM的时候,为了保证控制信道不受干扰,最好两个链路的控制信道不要做空分复用,比如gNB/Relay1通知B-D链路上的控制信道资源比如CORESET(control resource set),可选地Relay2调度Relay3/UE在A-U上发送的信道或信号不要占有B-D链路上的控制信道占有的时频资源。需要说明一个CORESET对应的时域资源在这个CORESET关联的Search space中配置。或者Relay2向gNB/Relay1请求Relay2覆盖下的多个Relay3/UE发送的A-U的上行控制信道占有的资源,希望gNB/Relay1在A-U的上行控制信道占有的资源上不要分配B-D的信道或者信号,同时Relay2在A-U的上行控制信道占有的资源上不接收B-D上的信道或信号。
类似地,可以用上述分配方法协调两个链路的其他参考信号资源,其中所述参考信号资源包括:相位跟踪参考信号,测量参考信号,跟踪参考信号TRS,同步信号。
实例3
在本实例中,以B-U和A-D链路为例,为了两个链路采用SDM的复用方式,需要尽量保证两个链路的波束的隔离度比较高,为了A-D采用的波束到达B-U的信号质量比较低,从而就可以A-D和B-U之间采用SDM的复用方式,需要采用图5b所示的流程,如图5a所示,Relay2采用SRS向gNB/Relay1发送A-D打算采用的波束,然后gNB/Relay1在下行信道或者信号中给Relay2发送基于SRS得到的信道状态信息。
比如Relay2在图5a中给gNB/Relay1发送了P个SRS资源,其中不同的SRS资源代表不同的波束,gNB/Relay1给Relay2发送信道状态信息,其中所述信道状态信息中包括P2个SRS资源指示信息,gNB/Relay1和Relay2约定所述P2个SRS资源指示信息满足如下特征至少之一:是P个SRS资源中到达gNB/Relay1的信号质量最低的P2个SRS资源,P2个SRS资源和约定的第一SRS集合中的SRS空间接收参数不同(即P2个SRS资源和约定的第一SRS集合中的SRS到达gNB/Relay1的接收波束不同,和/或P2个SRS资源和约定的第一SRS集合中的SRS关于空间接收参数不满足QCL(quasi-co-location准共址关系)关系。
本实例中,所述信号质量可以为如下信号质量至少之一:RSRP(reference signal receiver power,信号接收功率),RSRQ(reference signal receiver quality,信号接收质量),SINR(Signal interference noise ratio,信干噪比),CQI(Channel Quality Indicator,信道质量指示)。
其中第一SRS集合包括如下SRS资源至少之一:
gNB/Relay1分配给Relay2的用途为Noncodebook非码本传输的SRS集合中包括的SRS,PUSCH的空间滤波参数就可以根据该SRS集合中的任意一个或者多个SRS资源得到,即这些SRS资源到达gNB/Relay1的性能比较好,可以用于PUSCH的候选波束。
gNB/Relay1分配给Relay2的用途为码本传输(codebook)的SRS集合中包括的SRS,PUSCH的预编码信息根据该SRS集合中的任意一个得到SRS资源和DCI中通知的基于该SRS资源的PMI得到。即这些SRS资源到达gNB/Relay1的性能比较好,可以用于PUSCH的候选波束。
gNB/Relay1分配给Relay2的PUCCH的空间滤波参数中包括的SRS资源,其中PUCCH的空间滤波参数可以是配置的PUCCH发送时采用的空间滤波参数,即PUCCH真实发送所采用的空间滤波参数,也可以是PUCCH的空间参数列表,比如RRC为PUCCH配置了4个空间滤波参数列表,MAC-CE(Medium Access Control control element中间接入控制单元)为PUCCH激活其中一个。则第一SRS集合中可以只包括MAC-CE激活中的空间滤波参数中包括的SRS,也可以是RRC配置的4个空间滤波参数中包括的SRS,即这些作为候选波束到达gNB/Relay1的性能都不错,从而需要A-D所用的波束和这些波束在不同的接收波束中。
上述信道反馈信息只包括SRS资源指示信息,指示的SRS资源满足预定特征,本实施例的另一种实施方式中,所述信道状态信息也可以包括如下信息至少之一:资源指示信息,信号质量,预编码信息比如PMI(Precoding matrix indicator预编码矩阵指示信息),RI(Rank Indicator,层数指示信息)。其中资源指示信息中的资源的信号质量可以是P个SRS资源中信号质量最优的,从而Relay2知道A-D如果采用这些波束会对B-D造成很大的干扰,从而需要在A-D中避免使用。
实例4
在本实例中,由于两个链路能否做SDM要看图2中的Relay2的能力,比如Relay2只有一个panel,就无法做SDM,或者Relay2覆盖下的UE和Backhaul链路上的波束隔离度比较高,比如图6a所示,Backhaul链路和Access链路的波束隔离度很好,处于Relay2的两个背对背的panel,所以Backhaul链路和Access链路之间可以空分复用。
而如果Relay2只有一个panel,或者Backhaul链路和Access链路的波束隔离度不好,则Backhaul链路和Access链路不能做SDM,从而Relay2向gNB1/Relay1发送的资源请求信息中包括空域资源请求,其中所述空域资源请求指示A-D所用的波束,gNB1/Relay1根据Relay2发送的上行测量参考信号的测量结果和资源请求信息中包括的空域资源,确定两个链路是否能做SDM。
或者Relay2通过测量,向gNB1/Relay1发送的资源请求信息,资源请求信息中告知两个链路的可用复用方式集合,两个链路的可用复用方式集合包括如下至少之一:TDM、FDM、SDM。
或者如图6b所示,两个链路能否做SDM是依赖于Relay2覆盖的UE的,从而资源 请求中的可用复用方式集合和时域资源之间有关联,不同的时域资源可以对应不同的两个链路的可用复用方式集合,和/或资源请求中的可用复用方式集合和频域资源之间有关联,不同的频域资源可以对应不同的两个链路的可用复用方式集合。
实例5
在本实例中,如图7所示,Backhaul链路和Access链路只能时分复用,不能频分,也不能空分时,且gNB/Relay1分配Backhaul的帧结构也分配Access的帧结构,但是由于Relay2侧会将B-U的发送时间提前,从而保证gNB/Relay1在图7所示的位置收到B-U,这样B-U之后如果紧邻A-D/A-U,Relay2侧就会有空闲,即帧结构在gNB/Relay1侧的结构为图7的上图所示,而在Relay2侧的结构由于B-U的提前,其结构就为图7中的下图所示,从而在图7方格所示的时域资源上,gNB/Relay1既分配B-U资源也分配A-D/A-U,即在gNB/Relay1侧看到B-U和A-D/A-U之间可以有时域重叠,但是Relay2侧两个信道还是时分的。
图8a~8b中,G1时间间隔为t1+2TX/RX,其中t1是gNB/Relay1到Relay2的传输时延,TX/RX表示是收发转化时间,G2表示收发转换时间,G3为t3+2TX/RX,t1是Relay2到Relay3/UE的传输时延,G4等于G1减去G2。
在如图8a所示,B-U和A-D频分复用,由于B-U在Relay2侧的提前,在n+4slot中,B-U和B-D之间有一段时间空闲,而A-D和A-U之间的间隔只是收发转化,当G4时间间隔远大于G3时(比如gNB/Relay1到Relay2的传输时延远大于Relay2到Relay3/UE的传输时延),A-D在不同时间段就可以对应不同的频域资源,这样当B-U和A-D频分复用的时候,A-D可占有的频域资源和时域资源有关联。从而存在如下方式:
方式一:
A-D占有的一个BWP中包括的PRB集合和时域资源有关联,比如在slot{n+2,n+3,n+4的前面},A-D对应的BWP1包括PRB集合为PRBk~PRBk+20,在slotn+4的后面,BWP1包括PRB集合为PRBk~PRBk+40,从而在不同的时域资源中DCI中指示BWP中的PRB集合的索引信息的比特数可以不同。
方式二:
A-D在不同的时域资源中对应不同的可用BWP集合,比如在slot{n+2,n+3,n+4的前面}中A-D可用的BWP只有BWP1,而在slotn+4的后面,A-D可用的BWP包括{BWP1,BWP2},DCI在可用的BWP中动态指示A-D的信道或者信号占有的BWP,其中BWP1包括PRBk~PRBk+20,BWP2包括PRBk+21~PRBk+40,从而在不同的时域资源中DCI中指示BWP指示信息的比特域的比特数可以不同。
方式三:
A-D在一个BWP中包括的PRB集合中可占有的PRB集合和时域资源之间有关联,比如BWP3包括PRBk~PRBk+40,比如在slot{n+2,n+3,n+4的前面},A-D可以在BWP3中包括的PRBk~PRBk+40中可占有的PRB集合为PRBk~PRBk+20在slotn+4的后面,A-D 可以在BWP3中包括的PRBk~PRBk+40中可占有的PRB集合为PRBk~PRBk+40,从而在不同的时域资源DCI中指示的A-D中PDSCH可占有的PRB的集合不同。
在本实例的另一种实施方式中,如图8c所示,如果B链路和A链路要实现slot级别内的动态共享,则可以第一资源分配指示信息中指示B/A资源是通过动态信令确定确定是B链路还是A链路,第一资源分配指示信息其他资源要么是A链路占用,要么是B链路占用。从而A链路的可用PRB资源在slot的前半部分和后半部分是不同的。
