可选地,该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。
终端设备120可以是移动的或固定的。
可选地,终端设备120可以指用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无 线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例对此并不限定。其中,可选地,终端设备120之间也可以进行终端直连(Device to Device,D2D)通信。
网络设备110可以为小区提供服务,终端设备120通过该小区使用的传输资源,例如频域资源,或者说频谱资源,与网络设备110进行通信。该小区可以是网络设备110对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备,但本申请并不限于此。该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备。此外,该无线通信系统100还可以包括网络控制器、移动性管理实体等其他网络实体。
通信系统100仅是举例说明,适用本申请的通信系统不限于此,例如,通信系统100中包含的网络设备和终端设备的数量还可以是其它的数量。下面以通信系统100为5G通信系统为例对本申请的技术方案进行说明。为了简洁,下文中的终端设备和网络设备不再附带附图标记。
随机接入是终端设备尝试接入通信网络的过程。在小区搜索过程之后,终端设备已经与网络设备(也可称为“小区”)取得了下行同步,因此终端设备能够接收下行数据。但终端设备需要与网络设备取得上行同步,以便于进行上行传输。终端设备可以通过随机接入过程与网络设备建立连接并取得上行同步。也就是说,通过随机接入,终端设备可以获得上行同步,并且获得网络设备为其分配的唯一的标识即小区无线网络临时标识(cell radio network temporary identity,C-RNTI)。因此,随机接入不仅可以应用在初始接入中,也可以应用在用户上行同步丢失的情况下。
随机接入过程通常可以由以下6类触发事件之一触发:
(1)初始接入(initial access)。
终端设备会从无线资源控制(radio resource control,RRC)空闲态(RRC_IDLE)进入RRC连接态(RRC_CONNECTED)。
(2)切换(handover)。
当终端设备需要与新的小区建立上行同步时,需要在新的小区发起随机接入。
(3)RRC连接重建(RRC connection re-establishment)。
终端设备在发生无线链路失败(radio link failure,RLF)后重新建立无线连接。
(4)RRC连接态下,下行数据到达时,上行处于“不同步”状态。
此时,下行数据到达后终端设备需要回复肯定应答(acknowledgement,ACK)或否定应答(negative acknowledgement,NACK)。
(5)RRC连接态下,上行数据到达时,上行处于“不同步”状态或没有PUCCH资源用于调度请求(scheduling request,SR)传输。
上行数据到达例如需要上报测量报告或发送数据时,如果上行处于“不同步”状态,终端设备可以发起随机接入过程;或者,如果允许已经处于上行同步状态的终端设备使用随机接入信道(random access channel,RACH)来替代SR的作用,那么上行处于“不同步”状态时,终端设备可以发起随机接入过程。
(6)RRC连接态下,为了定位,需要获得时间提前量(timing advance,TA)。
此外,还可能由于RRC激活态(RRC_INACTIVE)过渡、请求其它系统信息(other system information,OSI)或者波束失败恢复(beam failure recovery)等原因触发随机接入。
图2是4步随机接入的示意图。4步随机接入的流程可以包括以下四个步骤:
步骤1,终端设备发送消息(message,Msg)1。
终端设备可以通过物理随机接入信道(physical random access channel,PRACH)向网络设备发送Msg1,以告诉网络设备该终端设备发起了随机接入请求,该Msg1中携带随机接入前导码(random access preamble,RAP),RAP也可称为前导码、随机接入前导码序列、前导码序列等。网络设备能够根据Msg1估计其与终端设备之间的传输时延以及步骤3中Msg3所需的上行资源的大小。
步骤2,网络设备发送Msg2。
网络设备在接收到终端设备发送的Msg1后,向终端设备发送Msg2,即随机接入响应(random access response,RAR)消息。终端设备可以在RAR窗口(RAR window)内监听随机接入无线网络临时标识(random access radio network temporary identity,RA-RNTI)加扰的物理下行控制信道(physical downlink control channel,PDCCH),以接收该PDCCH调度的物理下行共享信道(physical  downlink shared channel,PDSCH),RAR消息承载于PDSCH中。其中,RAR消息可以采用下行控制信息(download control information,DCI)格式(format)1-0进行调度。
如果终端设备在RAR窗口内没有接收到网络设备回复的RAR消息,则认为此次随机接入失败。如果终端设备在RAR窗口内成功检测到RAR消息,且该RAR消息中携带的前导码的索引与Msg1中的前导码的索引相同,则终端设备可以停止检测RAR消息。终端设备可以使用RA-RNTI解扰RAR消息,RA-RNTI与终端设备发送Msg1所使用的PRACH相关。
RAR消息中可以包括针对多个发送前导码的终端设备的响应消息。其中,针对每个终端设备的响应消息中包括该终端设备采用的随机接入前导码索引(random access preamble identify,RAPID)、Msg3的资源分配信息、TA调整信息、以及临时小区无线网络临时标识(temporary cell radio network temporary identity,TC-RNTI)等。
步骤3,终端设备发送Msg3。
终端设备在收到RAR消息后,判断该RAR是否为属于自己的RAR消息,例如终端设备可以利用前导码索引进行核对,在确定是属于自己的RAR消息后,在RRC层产生Msg3,并向网络设备发送Msg3,其中可以携带终端设备的标识等。
针对不同的随机接入触发事件,4步随机接入过程终端设备在步骤3中发送的Msg3可以包括不同的内容。
例如,对于初始接入的场景,Msg3包括RRC层生成的RRC连接请求消息,其中可以携带终端设备的非接入层(non-access stratum,NAS)标识信息。此外,Msg3还可以携带例如终端设备的服务临时移动用户标识(serving temporary mobile subscriber identity,S-TMSI)或随机数等。
又例如,对于RRC连接重建场景,Msg3包括RRC层生成的RRC连接重建消息且不携带任何NAS消息。此外,Msg3还可以携带例如C-RNTI和协议控制信息(protocol control information,PCI)等。
又例如,对于切换场景,Msg3包括RRC层生成的RRC切换确认(RRC handover confirm)消息,其携带终端设备的C-RNTI。此外,Msg3还可携带例如缓冲状态报告(buffer status report,BSR)等信息。
对于其它触发事件例如上/下行数据到达的场景,Msg3可以包括终端设备的C-RNTI。
在一些情况下,上行传输通常使用终端设备特定的信息。例如,使用C-RNTI等对上行共享信道(uplink shared channel,UL-SCH)中承载的数据进行加扰。但此时冲突还未解决,因此对Msg3加扰时不能基于C-RNTI,而只能使用TC-RNTI。
步骤4,网络设备发送Msg4。
网络设备向终端设备发送Msg4,终端设备接收Msg4以完成竞争解决(contention resolution)。在RRC连接建立过程中,Msg4中可以携带RRC连接建立消息。
若Msg3中携带终端设备的唯一标识,例如C-RNTI或来自核心网的标识信息(比如S-TMSI或一个随机数),Msg4中会携带终端设备的唯一标识以指定竞争中胜出的终端设备,用于调度Msg4的PDCCH可以采用C-RNTI进行加扰。
若Msg3中未携带终端设备的唯一标识,例如,在初始接入过程中,Msg3不包括C-RNTI,则终端设备进行冲突解决的方法可以是:接收Msg4中的PDSCH并判断该PDSCH中的竞争解决ID和Msg3中发送的公共控制信道(common control channel,CCCH)服务数据单元(service data unit,SDU)是否匹配。其中,用于调度Msg4的PDCCH可以采用TC-RNTI进行加扰。
没有在竞争解决中胜出的终端设备将重新发起随机接入。
在5G通信系统中,终端设备在进行随机接入时,除了可以使用上述4步随机接入方式进行随机接入,还可以采用2步随机接入的方式。一种可能的方法是,将4步随机接入过程中的消息Msg1和Msg3作为2步随机接入过程中的第一条消息来发送;将4步随机接入过程中的Msg2和Msg4作为2步随机接入过程中的第二条消息来发送。
如图3所示,2步随机接入的流程可以包括以下两个步骤:
步骤1,终端设备发送第一条消息(可以称为MsgA)。
该第一条消息可以包括前导码和上行数据(或载荷)。该上行数据可以承载于上行信道,该上行信道例如可以为物理上行共享信道(physical uplink shared channel,PUSCH)。其中,该PUSCH例如可以承载有终端设备的标识信息以及RRC请求的原因等。第一条消息可以携带4步随机接入过程中的Msg1和Msg3中携带的部分或全部信息。
步骤2,网络设备发送第二条消息(可以称为MsgB)。
若网络设备成功接收到终端设备发送的第一条消息,则向终端设备发送第二条消息。该第二条消 息中例如可以包括冲突解决信息、C-RNTI分配信息、TA调整信息等。该第二条消息可以携带4步随机接入过程中的Msg2和Msg4中携带的部分或全部信息。
在2步随机接入过程中,该第二条消息携带针对单个终端设备的冲突解决信息(包括第一条消息中终端设备发送的与终端设备的标识相关的信息)、C-RNTI分配信息、TA调整信息等。此外,该第二条消息还可能携带RRC连接建立消息等。
由于2步随机接入过程的标准化方案还未最终确定,因此,这里仅以图3为例进行介绍,对于其中涉及的各个随机接入消息的定义还存在其它可能性,本申请不限定对2步随机接入过程中的各个随机接入消息的定义。本申请所述的方法适用于其它所有的2步随机接入过程。
在2步随机接入过程中,终端设备可以对接收到的MsgB进程解码并通过PUCCH发送HARQ反馈信息,以便于网络设备根据HARQ反馈信息决定是否进行MsgB的重传。MsgB可以携带多个终端设备的RAR信息,当这些终端设备成功接收到MsgB后,可以通过PUCCH反馈ACK。
网络设备可以通过DCI中的信息域PDSCH-to-HARQ_feedback timing indicator指示传输该DCI的时隙或该DCI调度的PDSCH对应的ACK/NACK的时隙。即,若DCI或DCI调度的PDSCH在时隙n中传输,则对应的ACK/NACK在时隙n+k内传输。PDSCH-to-HARQ_feedback timing indicator上述用于指示k的取值。对于DCI format 1_0,该信息域长度为3比特,对应的取值范围可以是{1、2、3、4、5、6、7、8}。对于DCI format 1_1,网络设备首先通过高层信令配置一个集合,该集合内包括I个元素,每个元素为k的可取值,该信息域长度为
Figure PCTCN2019109752-appb-000001
I为不大于8的正整数。
在确定了PUCCH所在的时隙之后,还需要确定PUCCH的资源位置。如果终端设备没有专用的PUCCH资源配置,如初始接入阶段RRC连接建立之前,终端设备可以根据系统消息中的pucch-ResourceCommon获得PUCCH资源集合。如下表所示,pucch-ResourceCommon指示下表中的一个PUCCH资源集合索引(index)。终端设备可以根据调度PDSCH的PDCCH的第一个CCE的编号n CCE,0,以及DCI中指示的PUCCH resource indicator信息,确定PUCCH资源集合中的PUCCH资源。确定的PUCCH资源包括PUCCH资源所在的时隙,循环移位(cyclic shift,CS)和物理资源块(physical resource block,PRB)。
表1
Figure PCTCN2019109752-appb-000002
表1是本申请提供的配置PUCCH的一个示例,可选地,本申请提供的配置PUCCH的配置信息还可以包括时域资源指示信息,例如,指示PUCCH位于哪个或者哪几个时隙内。
如果终端设备配置了专用的PUCCH资源集合,网络设备可以通过高层信令为终端设备配置一个或多个PUCCH资源。终端设备可以根据调度PDSCH的PDCCH的第一个CCE的编号,以及DCI中的PUCCH resource indicator信息,确定PUCCH资源集合中的PUCCH资源。
目前,调度承载MsgB的PDSCH传输的PDCCH只能携带一个终端设备的PDSCH-to-HARQ_feedback timing indicator和PUCCH resource indicator,终端设备根据该PDCCH的唯一的起始CCE的编号,结合系统消息中的pucch-ResourceCommon,可以确定一个PUCCH资源,当MsgB承载多个UE的RAR信息时,PDCCH指示的PUCCH不能满足多个终端设备的反馈需求。
下面,介绍本申请提供的发送或接收反馈信息的方法。
如图4所示,方法400包括:
S410,终端设备接收MsgB,所述MsgB包括至少两个RAR。
相应地,网络设备发送上述MsgB。
S420,确定目标次序信息,所述目标次序信息用于指示目标反馈资源在反馈资源集合中的位置。
S430,根据所述目标次序信息从所述反馈资源集合中确定所述目标反馈资源。
目标次序信息例如是终端设备的RAR,为了便于区分,可以将该终端设备的RAR称为目标RAR,目标RAR与目标反馈资源(即,用于该终端设备传输MsgB的反馈信息的资源)之间存在关联关系,终端设备可以基于目标RAR在多个RAR中的次序确定目标反馈资源在反馈资源集合中的位置。该反馈资源集合例如是表1所示的资源集合。
目标次序信息也可以是其它信息,例如,终端设备的标识(identifier,ID)或者终端设备的C-RNTI,终端设备可以根据终端设备的ID确定目标反馈资源在反馈资源集合中的位置,或者,终端设备可以根据终端设备的C-RNTI确定目标反馈资源在反馈资源集合中的位置。即,能够反映终端设备在多个终端设备(MsgB中的至少两个RAR对应的终端设备)中的次序的信息均可以被称为目标次序信息。
终端设备在确定目标反馈资源之前,可以从网络设备接收指示信息,该指示信息例如是承载PDSCH-to-HARQ_feedback timing indicator和PUCCH resource indicator的DCI,终端设备可以根据上述两个信息域和承载上述DCI的PDCCH的第一CCE的编号确定第一反馈资源。
第一反馈资源为多个次序信息中的一个次序信息对应的反馈资源,该多个次序信息例如是MsgB中的多个RAR。可选地,第一反馈资源为多个次序信息中的第一个次序信息或者最后一个次序信息对应的反馈资源。
终端设备可以在确定第一反馈资源后,根据目标次序信息在多个次序信息中的次序从反馈资源集合中确定所述目标反馈资源,其中,目标次序信息在所述多个次序信息中的次序与所述目标反馈资源在所述反馈资源集合中的次序相关。
例如,MsgB包含四个RAR,该四个RAR的次序从前到后分别为RAR1、RAR2、RAR3和RAR4,目标次序信息可以是RAR2,在该四个RAR中的次序为第二位;反馈资源集合包括四个反馈资源,该四个反馈资源的次序从前到后分别为资源1、资源2、资源3和资源4;若RAR2在该四个RAR的次序与目标反馈资源在该四个反馈资源的次序相同,则目标反馈资源为资源2;若RAR2在该四个RAR的次序与目标反馈资源在该四个反馈资源的次序相反,即,位于第一位的次序信息对应的反馈资源为位于倒数第一位的反馈资源,则目标反馈资源为资源3。目标次序信息在所述多个次序信息中的次序与所述目标反馈资源在所述反馈资源集合中的次序的关系还可以是其它关系。
上述示例中,第一反馈资源可以是与第一个次序信息对应的资源,例如,资源1或资源4;第一反馈资源还可以是与其它次序的次序信息对应的资源,例如,第一反馈资源是与第二个次序信息对应的资源,则第一反馈资源可以是资源2或资源3。
即,终端设备可以根据第一反馈资源(相当于参考资源)在反馈资源集合中的次序、以及目标次序信息在多个次序信息中的次序、以及目标次序信息在所述多个次序信息中的次序与所述目标反馈资源在所述反馈资源集合中的次序的关系,从反馈资源集合中确定目标反馈资源。
网络设备在发送MsgB之前也可以根据S420和S430确定目标反馈资源。
终端设备和网络设备确定目标反馈资源后,可以执行下列步骤。
S440,终端设备在所述目标反馈资源上发送所述MsgB的反馈信息。
相应地,网络设备在目标反馈资源上接收上述终端设备针对MsgB发送的反馈信息。
由于网络设备和终端设备能够基于目标次序信息确定终端设备的目标资源,即使DCI仅指示反馈资源集合中的一个反馈资源,两步随机接入过程中的多个终端设备也能确定属于自己的目标反馈资源,从而解决了两步随机接入过程中如何为多个终端设备指示上行反馈资源的问题。此外,方法400无需更改现有的DCI的内容,具有更好的兼容性。
可选地,终端设备或网络设备可以按照下述方法确定目标反馈资源。
根据目标次序信息在多个次序信息中的次序和第一反馈资源的标识信息,确定目标反馈资源对应的目标标识信息,目标标识信息与第一反馈资源的标识信息存在关联关系;
根据所述目标标识信息从反馈资源集合中确定目标反馈资源。
上述标识信息例如是PUCCH资源指示(PUCCH resource indicator,PRI)。
如图5所示,MsgB包括8个UE的RAR,该8个UE的RAR的次序从前到后依次为RAR1(UE1)、RAR2(UE2)、RAR3(UE3)、RAR4(UE4)、RAR5(UE5)、RAR6(UE6)、RAR7(UE7)、RAR8(UE8),第一反馈资源(PUCCH1)为第一个RAR对应的反馈资源,DCI中指示第一反馈资源的PRI为第一PRI(000)。
UE1收到DCI后,根据RAR1的次序为首位确定目标PRI为第一PRI,或者,根据RAR1的次 序为首位确定目标PRI为第一PRI经过预定义的规则处理后得到的PRI(000),随后基于PRI(000)确定PUCCH1为目标反馈资源。
UE2收到DCI后,根据RAR2的次序为第二位确定目标PRI为第一PRI经过预定义的规则处理后得到的PRI(100),随后基于PRI(100)确定PUCCH5为目标反馈资源。
其它UE也可以通过类似的方法确定各自的PRI,并最终确定自己的目标反馈资源。
可选地,为了使不同的UE的PUCCH资源之间的干扰尽量少,上述预定义的规则可以使得次序相邻的UE分配的PUCCH资源满足以下特点:时域间隔尽可能的大,和/或,频域间隔尽可能的大,和/或,循环移位间隔上尽可能的大。通过上述预定义的规则,可以减少不同UE的PUCCH之间的干扰,提高PUCCH的接收性能,减少MsgB的无效重传。
标识信息还可以是PDCCH的第一个控制信道单元(control channel element,CCE)编号。
如图6所示,MsgB包括8个UE的RAR,该8个UE的RAR的次序从前到后依次为RAR1(UE1)、RAR2(UE2)、RAR3(UE3)、RAR4(UE4)、RAR5(UE5)、RAR6(UE6)、RAR7(UE7)、RAR8(UE8),第一反馈资源(PUCCH1)为第一个RAR对应的反馈资源,PDCCH的第一个CCE编号为CCE(000)。
UE1收到上述PDCCH承载的DCI后,根据RAR1的次序为首位确定目标CCE编号为CCE(000),或者,根据RAR1的次序为首位确定目标CCE编号为CCE(000)经过预定义的规则处理后得到的CCE(000),随后基于CCE(000)确定PUCCH1为目标反馈资源。
UE2收到上述PDCCH承载的DCI后,根据RAR2的次序为第二位确定目标CCE编号为CCE(000)经过预定义的规则处理后得到的CCE(100),随后基于CCE(100)确定PUCCH5为目标反馈资源。
其它UE也可以通过类似的方法确定各自的目标CCE编号,并最终确定自己的目标反馈资源。
可选地,为了使不同的UE的PUCCH资源之间的干扰尽量少,上述预定义的规则可以使得次序相邻的UE分配的PUCCH资源满足以下特点:时域间隔尽可能的大,和/或,频域间隔尽可能的大,和/或,循环移位间隔上尽可能的大。通过上述预定义的规则,可以减少不同UE的PUCCH之间的干扰,提高PUCCH的接收性能,减少MsgB的无效重传。
上文详细描述了本申请提供的从反馈资源集合中确定目标反馈资源的几个示例,下面介绍本申请提供的反馈资源集合。
在本申请中,配置信息(例如pucch-ResourceCommon)可以配置1个时域资源(例如,1个时隙)内的反馈资源集合,也可以配置多个时序资源内的反馈资源集合。可选地,配置信息可以包含指示时域资源的信息域,该信息域可以指示时域资源的数量和/或位置。
例如,UE可以根据pucch-ResourceCommon配置,以及所有可能的PUCCH resource indicator取值,和PDCCH的CORESET中的所有可能的第一个CCE的编号确定的一个可用的PUCCH资源集合(即,反馈资源集合)。可用的PUCCH资源集合中的不同PUCCH资源之间在时域、频移、循环移位中的至少一个维度是不同的,以保持彼此正交。其中,pucch-ResourceCommon配置中包含PUCCH的时隙信息,如包含两个不同的时隙。除了新引入的时隙信息,pucch-ResourceCommon可以复用4步随机接入的配置信息,也就是NR Rel-15的现有技术,也可以针对2步随机接入新定义配置信息。
在本申请中,“彼此”指的是任意两个之间,例如,M个反馈资源的时域资源彼此相异,指的是,该M反馈资源中任意两个反馈资源的时域资源不同。
如图7所示,UE确定的可用的PUCCH资源集合包括时域、频移、循环移位中的至少一个维度不同的PUCCH资源。在一个时隙内,可用的PUCCH资源集合包括不同的PRB和CS的共16个PUCCH资源。对于两个时隙的情况,可用的PUCCH资源集合包括不同时隙、PRB和CS的共32个PUCCH资源。它们处于初始上行(initial UL)部分带宽(bandwith part,BWP)内。
通过DCI中的PDSCH-to-HARQ_feedback timing indicator和PUCCH resource indicator,以及PDCCH的第一个CCE的编号,确定MsgB中承载的RAR对应的UE中的第一个UE的PUCCH资源。其余UE的PUCCH在第一个UE的PUCCH的基础上,按照一定的规则,如UE对应的RAR在MsgB中的位置,确定各自的PUCCH资源在可用的PUCCH资源集合中的资源位置。
可选地,在可用的PUCCH资源集合中,如果包含多于一个时隙,按照先时域(时隙),再频域(PRB),最后循环移位(CS)的顺序进行PUCCH资源与UE的映射。
可选地,在可用的PUCCH资源集合中,如果包含一个时隙,按照先频域(PRB),再循环移位(CS)的顺序进行PUCCH资源与UE的映射。
可选地,对于频域映射,按照PUCCH资源所在的PRB之间的间隔由大到小的顺序映射。例如对于PUCCH资源所在的PRB编号为0,1,2,3,则映射顺序为0,3,1,2。
可选地,对于循环移位的映射,按照PUCCH资源所对应的CS的间隔由大到小的顺序映射。例 如对于CS={0,3,6,9},映射顺序为0,6,3,9。
以两个时隙为例,如图7所示,如果DCI中指示的时隙n上PUCCH资源为PRB 0上CS=0的PUCCH资源,则MSG B中承载的RAR对应的UE的PUCCH按照如下顺序映射:
第1个UE:时隙n上PUCCH资源为PRB 0上CS=0的PUCCH资源;
第2个UE:时隙n+1上PUCCH资源为PRB 0上CS=0的PUCCH资源;
第3个UE:时隙n上PUCCH资源为PRB 3上CS=0的PUCCH资源;
第4个UE:时隙n+1上PUCCH资源为PRB 3上CS=0的PUCCH资源;
第5个UE:时隙n上PUCCH资源为PRB 1上CS=0的PUCCH资源;
第6个UE:时隙n+1上PUCCH资源为PRB 1上CS=0的PUCCH资源;
第7个UE:时隙n上PUCCH资源为PRB 2上CS=0的PUCCH资源;
第8个UE:时隙n+1上PUCCH资源为PRB 2上CS=0的PUCCH资源;
第9个UE:时隙n上PUCCH资源为PRB 0上CS=6的PUCCH资源;
……
以此类推,直到映射完所有的UE。上述UE映射在PUCCH资源上,可以理解为UE确定PUCCH资源,或者,RAR(或其它次序信息)映射在PUCCH资源上,或者,UE确定次序信息与反馈资源之间的映射关系或对应关系。
上述示例不应被理解为对本申请的限定,例如,本申请对第2个UE映射的PRB和CS不做限定;UE3与UE1的时域资源相同,当映射UE3时,UE3映射的PUCCH资源的频域资源和CS与UE1的频域资源和CS不同即可,并不限定必须是PRB=3和CS=0;类似地,UE9与UE1的时频资源相同,UE9映射的PUCCH资源的CS与UE1的CS不同即可,并不限定必须是CS=6。
上述方案按照预定义的规则隐式指示所有UE的PUCCH资源,可以减少DCI或者MsgB的信令开销。通过先时域(时隙),再频域(PRB),最后循环移位(CS)的顺序进行映射,可以尽量减少不同UE的PUCCH之间的干扰,提高PUCCH的接收性能,减少MsgB的无效重传。
UE与反馈资源的映射关系还可以如图8所示。
图8中,UE确定的可用的PUCCH资源集合包括时域、频移、循环移位中的至少一个维度不同的PUCCH资源。在一个时隙内,可用的PUCCH资源集合包括不同的PRB和CS的共16个PUCCH资源。对于两个时隙的情况,可用的PUCCH资源集合包括不同时隙、PRB和CS的共32个PUCCH资源。它们处于initial UL BWP内。
可选地,网络设备配置的反馈资源为时隙n中的反馈资源,时隙n+1中的反馈为终端设备自己确定的。或者,网络设备也可以配置多个时隙中的反馈资源,当网络设备配置的反馈资源不足以分配给MsgB中全部RAR对应的UE时,UE可以基于网络设备配置的反馈资源自己确定反馈资源,即,在本申请中,终端设备确定的反馈资源集合中的反馈资源可以全部是网络设备配置的,也可以部分是网络设备配置的。
如图8所示,DCI中的PDSCH-to-HARQ_feedback timing indicator指示PUCCH资源集合位于时隙n,包含16个PUCCH资源。MsgB中包含的RAR对应32个UE,该32个UE的次序从UE1开始依次排到UE32,其中,UE1-UE16按照规则映射到时隙n的16个PUCCH资源上。从UE 17开始,按照相同的规则,映射到时隙n+1上的PUCCH资源集合。
基于上述方案,在不改变现有的DCI中的指示信息的前提下,UE可以根据MsgB携带的RAR对应的UE的个数,灵活地扩充PUCCH资源。
