本发明涉及通信技术领域,尤其涉及一种信号发送、接收方法及相关设备。
在无线通信***,如新无线(new radio,NR)通信***中,用户设备(user equipment,UE)和基站(basestation,BS,或g Node B,gNB)之间交互的信息通过物理信道进行承载。其中,UE发送的数据,也即上行数据,通常通过物理上行共享信道(physical uplink shared channel,PUSCH)承载;UE发送的控制信息,也即上行控制信息,通常通过物理上行控制信道(physical uplink control channel,PUCCH)承载。此外,UE还可以发送探测参考信号(sounding reference signal,SRS),gNB通过接收UE的SRS,可以估计UE在不同频率上的信道质量。
在无线通信中,对于一些深覆盖场景,如小区边沿,或者地下室等,无线信号传播的路径损耗非常严重。现有方案中,为了增强基站在接收UE发送的信号时的检测性能或解调性能,需要采用覆盖增强方法,通常的覆盖增强的有UE重复发送、基站接收多次重复发送的数据并进行合并解调等。数据的重复发送和接收相当于占用了更多的资源传输同样多的数据,因此,现有的方法会导致用户的感知速率的下降。
发明内容

本申请实施例为了解决现有技术中,在一些深覆盖场景下,无线信号传播的路径损耗非常严重导致终端设备发送的信号到达网络设备时非常微弱,针对现有方案中的覆盖增强方法会导致用户的感知速率下降的情况,本申请提出了采用至少一个邻近的终端设备,转发终端设备所发送的信号的方式,使得网络设备接收与现有方案中相同次数第二终端设备发送的信号时,还接收到了邻近的终端设备转发的第二终端设备发送的信号,等效地提升了网络设备接收到的第二终端设备的信号的强度,并且提升了终端设备的感知速率。
下面结合附图对本申请的实施例进行描述。
为了更好的理解本申请实施例中的信号发送、接收方法,本申请实施例提供的一种应用信号发送、接收方法的通信***的结构示意图。请参阅图1,图1为本申请实施例提供了一种通信***的结构示意图。如图1所示,通信***包括网络设备和多个终端设备,网络设备例如为接入网设备,例如基站,或者也可以是RSU等设备,终端设备包括至少一个第一终端设备、至少一个第二终端设备,第一终端设备可以接收/转发其它终端设备发送的信号,其中,第二终端设备在第一传输时间和第二传输时间内发送相同的信号,第一终端设备在第一传输时间接收第二终端设备发送的信号,第一终端设备在第二传输时间发送接收到的信号,第一终端设备在第二传输时间发送信号时,不改变信号的特征;基站接收第二终端设备在第一传输时间和第二传输时间内发送的信号,以及接收第一终端设备在第二传输时间发送的信号,第一传输时间和第二传输时间不重叠,第一传输时间包括N

请参阅图2,图2为本申请实施例提供了一种信号发送、接收方法的交互示意图。如图2所示,信号发送、接收方法包括步骤S201-S204,具体如下:
S201、第二终端设备在第一传输时间和第二传输时间发送信号。
其中,第二终端设备发送的信号的冗余版本号为RV0,当然还可以包括其它冗余版本号,例如RV1、RV2、RV3等,此处仅为举例说明,不作具体限定。S202、第一终端设备在第一传输时间接收信号。
其中,第二终端设备在第一传输时间中发送信号,第一终端设备在第一传输时间接收第二终端设备发送的信号。
S203、第一终端设备在第二传输时间发送信号。
其中,第一终端设备在第二传输时间发送的信号与在第一传输时间接收的信号相同。由于第二终端设备在第一传输时间和第二传输时间中发送的信号相同,因此在第二传输时间中,第一终端设备和第二终端设备发送的信号相同。
其中,第一传输时间和第二传输时间不重叠,第一传输时间包括个N
1个时间单元,第二传输时间包括N
2个时间单元,N
1个时间单元在N
2个时间单元之前,所述N
1个时间单元的索引为{0,1,……N
1-1},所述N
2个时间单元的索引i为{0,1,…,N
2-1},第一终端设备在N
2个时间单元的索引为i的时间单元发送的信号与第一终端设备在N
1个时间单元中的索引为(i mod N
1)的时间单元中接收到的信号相同,N
1和N
2为正整数。mod为求余运算,i mod N
1为i除以N
1的余数。
可选的,网络设备通过向第一终端设备和第二终端设备发送下行控制信息(downlink control information,DCI),DCI中包括指示信息,该指示信息用于指示第一终端设备在第一传输时间接收信号,且在第二传输时间发送在第一传输时间中接收到的信号;可选的,该指示信息用于指示第二终端设备在第一传输时间和第二传输时间中发送信号。
一种可能的方法为,若指示信息的值属于预定义的第一集合,则指示信息指示第一终端设备在第一传输时间接收信号,且在第二传输时间发送在第一传输时间中接收到的信号;若指示信息的值属于预定义的第二集合,则该指示信息指示第二终端设备在第一传输时间和第二传输时间中发送信号。可选的,网络设备在向第一终端设备和第二终端设备发送DCI之前,还可以为包括第一终端设备和第二终端设备在内的多个终端设备各配置一个索引,该索引可以为任意的标识,例如:数字、字母等。
可选的,一种可能的DCI中的指示信息的指示方法为,若终端设备的索引与指示信息的值相同,则该终端设备为第二终端设备,反之为第一终端设备。类似的,DCI中的指示信息的指示方法也可以为,若终端设备的索引与指示信息的值相同,则该终端设备为第一终端设备,反之为第二终端设备。
可选的,以终端设备的索引与指示信息的值相同则该终端设备为第二终端设备为例,一种可能的指示信息的指示方法为:对于多个终端设备组成的协作传输组,指示信息的可以为DCI中一个[log
2(N)]比特的字段,该[log
2(N)]比特字段的值指示了协作传输组中的终 端设备属于第二终端设备还是属于第一终端设备。例如,N=4时,特定字段长[log
2(N)]=2比特,由4个终端设备组成的协作传输组,该组内的4个终端设备的索引分别为“0”,“1”,“2”,“3”,该协作传输组的终端设备接收包括指示信息的DCI。对于索引为0的终端设备,其对应的第一集合为{1,2,3},对应的第二集合为{0};对于索引为1的终端设备,其对应的第一集合为{0,2,3},对应的第二集合为{1};对于索引为2的终端设备,其对应的第一集合为{0,1,3},对应的第二集合为{2};对于索引为3的终端设备,其对应的第一集合为{0,1,2},对应的第二集合为{3}。示例性的,该组内4个终端设备接收包括指示信息的DCI,当DCI中的指示信息的值为3时,该指示信息的值对于索引为3的终端设备而言属于第二集合,因此索引为3的终端设备为第二终端设备,该终端设备在第一传输时间和第二传输时间发送信息;而类似的,索引不为3(也即为0,1,2)的终端设备则为第一终端设备,这些终端设备在第一传输时间接收信号,在第二传输时间发送其在第一传输时间接收到的信号。上述方法中,指示信息所占用的比特数较少,有利于减少DCI的比特开销。
可选的,另一种可能的指示信息的指示方法为:对于N个终端设备组成的协作传输组,指示信息可以为DCI中的一个N比特的特殊字段,该特殊字段中的每比特的取值为0或1,每个终端设备的索引与0至N-1之间的整数值一一对应,每个索引值与比特位一一对应;例如索引值为0,则对应特殊字段的第一比特位,索引值为N-1对应特殊字段的第N比特位,第一比特位至第N比特位与特殊字段从左至右(从高到低)的第一位置至第N位置一一对应。
其中,对于该协作传输组中的每个终端设备,预设的第一集合可以均为{0}(其表示比特位的取值为0),预设的第二集合可以均为{1}(其表示比特位的取值为1)。例如,4个终端设备组成的协作传输组,指示信息的长度为4比特,4个终端设备的索引分别为{0,1,2,3}中的值;该4个终端设备接收同一个包括指示信息的DCI,若指示信息的值为‘0110’,则可以确定出索引为0和3的终端设备为第一终端设备(第一比特位和第四比特位取值为0),索引为1和2的设备为第二终端设备(第二比特位和第三比特位的取值为1)。因此,通过上述方法可以在一个标识信息中标识多个第一终端设备和多个第二终端设备,提升了指示的灵活程度。
当然,还可以有其它指示信息的指示方式,指示信息的作用为:指示信息的值属于预定义的第一集合,则第二终端设备在第一传输时间和第二传输时间发送信号;指示信息的值属于预定义的第二集合,则第一终端设备在第一传输时间接收信号,在第二传输时间发送信号,本申请实施例的指示信息设置方式仅为举例说明,不作具体限定。
在一个可能的实施例中,网络设备向终端设备发送特定DCI,若终端设备接收到该特定DCI后,则确定其为第一终端设备,即在第一传输时间接收信号,在第二传输时间发送在第一传输时间中接收到的信号。一种可能的方法为,通过对特定DCI使用特定的无线网络临时标识(radio network temporaryidentity,RNTI)进行加扰,并为通知终端设备该特定的RNTI;当终端设备成功使用特定RNTI对该特定DCI进行解扰,即可确定该终端设备为第一终端设备。因此,本示例中,无需在DCI中设置指示信息,也即无需在DCI中新增指示信息字段,则可以使得终端设备确定出具体的传输方式,也即在第一传输时间接收 信号,在第二传输时间发送在第一传输时间中接收到的信号,因此本方法可以在不改变现有的DCI载荷的情况下,使得终端设备可以确定出具体的传输方式,能够减少DCI中的比特开销。
在一个可能的实施例中,网络设备还可以向终端设备发送不同的DCI,终端设备根据接收到的DCI,来确定不同的传输方式,不同的DCI可以通过RNTI区分,也可以有其他区分方式,本申请不做具体限定。
可选的,第一传输时间和第二传输时间可以通过无线资源控制(Radio Resource Control,RRC)信令配置,也可以是在DCI中进行指示,或者通过RRC信令和DCI结合的方式进行指示,具体例如可以是:指示第一传输时间的和第二传输时间的时长,比如时隙数,也可以是第一传输时间占总第一传输时间和第二传输时间之和的比例值,还可以是第一传输时间与第二传输时间的比例值,当然还可以是其它的方式进行配置或指示,此处仅为举例说明,不作具体限定。
在一个可能的实施例中,DCI中还可以携带信号重复发送的次数K,终端设备在收到DCI之后,确定其为第二终端设备时,在收到DCI的时刻之后的预设时刻,根据DCI调度的PUSCH对信号重复发送K次,其中,可以在第一传输时间中的N
1个时间单元中发送,在第二传输时间中的N
2个时间单元中发送,K为N
1与N
2之和,预设时刻可以通过一个预定义的间隔时间以及承载DCI的时频资源的结束时刻确定。
可选的,N
1为第二终端设备发送信号使用的循环冗余版本数的整数倍。这样有利于第一终端设备在第一传输时间中接收到第二终端设备发送的所有循环冗余版本的信号,因此第一终端设备在第二传输时间中发送在第一传输时间中接收到的信号时,可以发送第二终端设备发送的所有循环冗余版本的信号,也即对第二终端设备发送的所有循环冗余版本的信号进行增强。
可选的,若第一终端设备具有信号功率放大功能,则第一终端设备在第二传输时间发送信号时,可以对发送的信号进行放大,也即提升发送的信号的发射功率,从而可以进一步的增强网络设备接收到的信号的强度,其中,发送功率或放大倍数可以是网络设备预先配置的。

其中,网络设备在第一传输时间和第二传输时间接收的信号均为相同的信号,即,网络设备在第二传输时间接收的第一终端设备发送的信号和第二终端设备发送的信号为相同的信号,且该信号与终端设备在第一传输时间接收的信号相同。
对于第一终端设备,在S201~S203的步骤中,第一终端设备确定第一传输时间和第二传输时间,其中,第一传输时间包括N1个时间单元,第二传输时间包括N2个时间单元,且第一传输时间和第二传输时间无交叠,N1和N2为正整数;第一终端设备在第一传输时间中接收信号,且在第二传输时间中发送在第一传输时间中接收到的信号。
在一种可能的实施方式中,第一传输时间和第二传输时间构成的传输时间包括N1+N2个时间单元,第一传输时间包括的N1个时间单元为该N1+N2个时间单元中的前N1个时间单元,第二传输时间包括的N2个时间单元为该N1+N2个时间单元中的后N2个时间单元。
在一种可能的实施方式中,记第一传输时间包括的N1个时间单元的索引为{0,1,…… N1-1},所述第二传输时间包括的N2个时间单元的索引为{0,1,…,N2-1};
在所述N2个时间单元中,所述终端设备在索引为i的时间单元发送的信号与在所述N1个时间单元中的索引为(i mod N1)的时间单元中接收到的信号相同,其中,i为整数,0≤i≤N2-1,mod为取模运算。
当然,本实施例中可以具有多个第一终端设备,其具体的信号处理流程与上述的第一终端设备的信号处理流程相同。

其中,终端设备确定自己属于第一终端设备或第二终端设备的方法,参照前述图2所述实施例中的确定方法,此处不再赘述。
请参阅图4,图4为本申请实施例提供了另一种信号发送、接收方法的交互示意图,并以终端设备发送的信号为PUSCH为例进行说明。如图4所示,第二终端设备在第一传输时间和第二传输时间发送冗余版本号为RV0、RV2、RV3、RV1的信号,N1为4,即冗余版本数4的1倍;第一终端设备在第一传输时间接收RV0、RV2、RV3、RV1的信号,在第二传输时间中发送在第一传输时间中接收到的RV0、RV2、RV3、RV1的信号,第一终端设备在N2个时间单元的索引为i的时间单元发送的信号与第一终端设备在第一传输时间中的4个时间单元中的索引为(i mod 4)的时间单元中接收到的信号相同。冗余版本的具体顺序可以是预定义的,或者是通过RRC信令配置的,或者DCI通知的,或者是预定义与DCI通知结合、或RRC信令与DCI通知结合的方式确定的。通过本实施例中的方法,当第二终端设备发送的信号的冗余版本数大于1时,依然可以使得在第二传输时间中第一终端设备发送的信号在各时间单元中与第二终端设备发送的信号相同,起到信号增强的作用。

请参阅图6,图6为本申请实施例提供了另一种信号发送、接收方法的交互示意图,并以终端设备发送的信号为PUSCH为例进行说明。如图6所示,第二终端设备在进行信号传输时,可以采用时间单元间跳频(如时隙间跳频)的方法对信号进行发送,本实施例以时隙间跳频的方式进行信号传输为例,第二终端设备在第三传输时间和第四传输时间发送信号,第一终端设备在第三传输时间接收信号,在第四传输时间发送信号。具体如图所示,在第一频率上传输4组不同的RV版本的信号,在第二频率上传输4组不同的RV版本的信号,不同组的信号中RV版本号相同的信号为相同信号。其中,N1个时间单元为第三传输时间的部分或全部,N2个时间单元为第四传输时间的部分或全部,即可以理解为,第三传输时间可以包括至少一个完整的第一传输时间,第四传输时间可以包括至少一个完整的第二传输时间,第三传输时间和第四传输时间中RV版本号相同的信号为相同信号。
