上行传输时间的确定方法、终端及网络侧设备
交叉引用
本申请要求在2022年11月07日提交中国专利局、申请号为202211385356.2、名称为“上行传输时间的确定方法、终端及网络侧设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于通信技术领域，具体涉及一种上行传输时间的确定方法、终端及网络侧设备。
背景技术
在第三代合作伙伴计划(Third Generation Partnership Project，3GPP)版本16(Release 16，R16)中引入了多发送和接收点(transmission and reception point，TRP)传输技术来提升数据传输的吞吐量。为了保证上行传输的正交性，避免小区内(intra-cell)干扰，基站要求来自同一子帧但不同频域资源的不同终端(User Equipment，UE)的信号到达基站的时间基本上是对齐的。基站只要在循环前缀(Cyclic Prefix，CP)范围内接收到UE所发送的上行数据，就能够正确地解码上行数据。因此，上行同步要求来自同一子帧的不同UE的信号到达基站的时间都落在CP之内。定时提前量(Timing Advance，TA)用于UE上行传输，目的是确保UE上行数据包在希望的时间内到达基站。具体的实现可以简单概括为基站测量上行信号，预估由于距离引起的射频传输时间的延迟，给UE发送定时提前命令(Timing Advance Command，TAC)，通知UE上行传输提前发送相应的时间量。
相关技术中，在多TRP场景中，发往不同TRP的上行传输采用相同的TA。考虑到不同TRP的位置差异较大，共用一个上行传输时间可能使得不同用户到达一个TRP的上行传输时间差超出CP，从而造成用户间干扰，进而降低上行传输的性能，无法达到多TRP传输提升吞吐量的目的。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VehicleUser Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请 实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或无线保真(Wireless Fidelity，WiFi)节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmission Reception Point，TRP)或所属领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的上行传输时间的确定方法进行详细地说明。
首先对定时提前组(time advance group，TAG)进行解释说明。
TAG应用于载波聚合场景，多个载波引入的时延不同，或者是不同载波的主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)的位置差异较大，此时不能用统一的TA来进行处理。因此引入TAG的概念，同一个TAG对应的TA相同，不同TAG对应不同的TA值。图2是根据本申请一实施例的一种TAG和小区之间的关联关系示意图。如图2所示，主小区组(Master Cell group，MCG)包括主小区PCell、辅小区SCell1、辅小区SCell2和辅小区SCell3。辅小区组(Secondary Cell group，SCG)包括主辅小区PSCell、辅小区SCell4、辅小区SCell5和辅小区Scell6。主小区定时提前量组(PCell TAG，PTAG)为包含主小区的TAG，辅小区定时提前量组(SCell TAG，STAG)为包含辅小区的TAG。在图2所示关联关系中，在MCG内，PTAG关联主小区Pcell和辅小区SCell1，STAG关联辅小区SCell2和辅小区SCell3。在SCG内，PTAG关联主辅小区PScell和辅小区Scell4，STAG关联辅小区Scell5和辅小区Scell6。
图3是根据本申请一实施例的一种上行传输时间的确定方法的示意性流程图。如图3所示，该方法应用于终端，包括以下步骤S302-S306：
S302，从网络侧设备接收一个或多个服务小区对应的参数配置信息；参数配置信息包括TAG标识，TAG标识关联有各自的传输对象。
其中，每个服务小区配置有一个或多个TRP。
每个TAG标识分别关联一个或多个发送至TRP的传输对象。TAG标识和传输对象之间的关联关系可通过以下几种方式明确。一种方式：在每个服务小区对应的参数配置信息中，每个TAG标识关联有一个或多个发送至TRP的传输对象。另一种方式：服务小区对应的参数配置信息中仅包括TAG标识，网络侧设备通过其它配置信息配置与每个TAG标识关联的传输对象，其中，其它配置信息的配置信息不做限定。再一种方式：服务小区对应的参数配置信息中仅包括TAG标识，并在网络侧设备和终端的通信协议中约定每个 TAG标识关联的传输对象。当然，除上述列举的几种方式之外，还可通过其它方式来明确TAG标识和传输对象之间的关联关系，本申请实施例对此不做限定。
可选地，传输对象可包括以下至少一项：控制资源集合池索引(如coresetpoolindex0、coresetpoolindex 1)、信道探测参考信号(Sounding Reference Signal，SRS)资源集、传输配置指示(Transmission Configuration Indicator，TCI)状态、TCI状态池、同步信号块(Synchronization Signaling Block，SSB)分组、物理小区标识(Physical Cell ID，PCI)、天线端口组。
可选地，针对每个服务小区的参数配置信息，可包括以下几种情况：参数配置信息包括两个TAG标识，每个TAG标识分别关联一个上行传输对象；或者，参数配置信息包括一个TAG标识，TAG标识关联两个传输对象；或者，参数配置信息包括一个TAG标识，TAG标识关联一个传输对象。
若网络侧设备配置的参数配置信息中配置了TAG标识与传输对象之间的关联关系，则针对每个服务小区的参数配置信息，TAG标识与传输对象之间的关联关系可以包括以下a1-a3中的任一种：
a1，参数配置信息包括两个TAG标识和两个传输对象，其中，每个TAG标识分别关联一个上行传输对象。
如图4(a)所示，某一服务小区的参数配置信息中包括两个TAG标识，即TAG0和TAG1，每个TAG标识分别关联一个传输对象，其中，TAG0关联coresetpoolindex0，TAG1关联coresetpoolindex1。
a2，参数配置信息包括一个TAG标识及其关联的两个传输对象。
如图4(b)所示，某一服务小区的参数配置信息中包括一个TAG标识，即TAG0，且TAG0关联两个传输对象，分别是coresetpoolindex0和coresetpoolindex1。
a3，参数配置信息包括一个TAG标识及其关联的一个传输对象。
如图4(c)所示，某一服务小区的参数配置信息中包括一个TAG标识，即TAG2，且TAG2仅关联一个传输对象，即coresetpoolindex1。
可选地，多个服务小区配置有相同的TAG标识，相同的TAG标识关联相同的传输对象相同。例如，从图4(a)-4(c)可看出，与TAG0关联的传输对象均包括coresetpoolindex0。
S304，根据参数配置信息，在一个或多个服务小区对应的传输对象中确定终端所在的目标服务小区对应的目标传输对象。
如上所述，目标服务小区对应的目标传输对象可包括一个或多个，在确定出目标服务小区对应的目标传输对象之后，针对每个目标传输对象，分别确定目标传输对象的上行传输时间。
S306，根据与目标传输对象相关联的目标TAG标识，确定目标传输对象的上行传输时间。
在本申请实施例中，通过从网络侧设备接收一个或多个服务小区对应的参数配置信息， 该参数配置信息包括TAG标识，各TAG标识关联有各自的传输对象，根据参数配置信息，在一个或多个服务小区对应的传输对象中确定终端所在的目标服务器小区对应的目标传输对象，进而根据与目标传输对象相关联的目标TAG标识，确定目标传输对象的上行传输时间。可见，该技术方案能够由网络侧设备预先配置一个或多个服务小区对应的参数配置信息并发送给终端，从而使终端能够根据所在目标服务小区对应的TAG标识，动态确定目标传输对象的上行传输时间，而并非所有的传输对象都采用相同的上行传输时间，且能够确保多TRP的上行传输时间准确，提升上行传输的性能。
在一个实施例中，每个TAG标识关联一个下行帧时间。在根据与目标传输对象相关联的目标TAG标识，确定目标传输对象的上行传输时间时，可执行为以下步骤A1-A3：
步骤A1，确定目标TAG标识对应的上行时间调整量。
步骤A2，根据目标TAG标识对应的下行帧时间，确定目标TAG标识对应的上行参考时间。
其中，步骤A1和步骤A2的执行顺序不做限定。比如，除按照本实施例示出的先确定上行时间调整量、然后再确定上行参考时间的顺序之外，还可以先确定上行参考时间，然后再确定上行时间调整量。或者，可以同时确定上行参考时间和上行时间调整量。
步骤A3，根据上行参考时间和上行时间调整量，确定目标传输对象的上行传输时间。
下面详细说明如何确定目标TAG标识对应的上行参考时间以及上行时间调整量。
在一个实施例中，执行步骤A2，即确定上行参考时间时，首先根据目标TAG标识，在第一服务小区中确定参考小区；然后将参考小区对应的传输对象的下行帧时间确定为目标TAG标识对应的上行参考时间。其中，目标TAG标识指示的目标TAG对应多个第一服务小区。这样能确保TAG标识对应的TAG确定出准确的与目标传输对象对应的上行参考时间。
可选地，将配置有两个TAG标识、且每个TAG标识分别关联一个传输对象的第一服务小区确定为参考小区。或者，将仅配置有一个TAG标识的第一服务小区确定为参考小区。这样，终端只需要测量该服务小区(即参考小区)对应的下行时间作为上行参考时间，而不需要区分目标对象后再确定上行参考时间，从而降低终端实现复杂度。
可选地，将配置有两个TAG标识、且每个TAG标识分别关联一个传输对象的第一服务小区确定为参考小区时，第一服务小区(或参考小区)对应的传输对象的下行帧时间基于第一服务小区对应的传输对象的下行链路(Downlink，DL)参考信号或DL信道测量得到。
其中，第一服务小区对应的传输对象的DL参考信号或DL信道可由网络侧设备配置或指示。基于此，终端可基于网络侧设备的配置信息或指示信息确定第一服务小区对应的传输对象的DL参考信号或DL信道。可选地，终端接收网络侧设备发送的无线资源控制(Radio Resource Control，RRC)配置信息，RRC配置信息中携带有各服务小区对应的传输对象的DL参考信号或DL信道信息。终端根据RRC配置信息，即可确定出第一服务 小区对应的传输对象的DL参考信号或DL信道。
在一个实施例中，Intra-cell mTRP配置下，即服务小区内配置有多个TRP。若终端所在的目标服务小区内配置有多个TRP，目标服务小区为配置有两个TAG标识的主小区。这种情况下，目标服务小区配置的两个TAG标识中，每个TAG标识对应的TAG均被配置为第一类TAG，或者，其中一个TAG标识对应的TAG被配置为第一类TAG。第一类TAG可以是PTAG，即包括主小区的TAG。
可选地，目标服务小区对应的两个TAG标识中，在每个TAG标识对应的TAG均为第一类TAG的情况下，若第一类TAG失去同步，则释放与第一类TAG关联的传输对象的上行传输。在其中一个TAG标识对应的TAG被配置为第一类TAG的情况下，若第一类TAG失去同步，则释放终端对应的所有上行传输。
本实施例中，每个TAG都会配置一个时间同步计时器(Time Alignment Timer，TAT)，用于控制TAG内服务小区的同步时间长度，当终端收到TAC时就会启动TAT，当TAT过期时终端不能进行上行传输。本实施例中所述的“失去同步”，可理解为对应的TAT过期。第一类TAG失去同步，即第一类TAG对应的TAT过期。
可选地，目标服务小区对应的两个TAG标识中，关联的传输对象为coresetpoolindex 0的TAG标识对应的TAG为第一类TAG。
可选地，网络侧设备可对第一类TAG进行配置，终端可根据网络侧设备的配置信息来确定两个TAG标识中哪个TAG标识对应的TAG为第一类TAG。基于此，终端可接收网络侧设备发送的RRC配置信息，RRC配置信息中携带有第一类TAG对应的TAG标识信息，终端可根据网络侧设备发送的RRC配置信息，确定两个TAG标识中的其中一个TAG标识对应的TAG为第一类TAG。
在一个实施例中，Inter-cell mTRP配置下，即服务小区之间配置有多个传输对象。终端所在的目标服务小区为配置有两个TAG标识的主小区。这种情况下，终端可确定与目标传输对象(即终端所在的目标服务小区对应的传输对象)相关联的TAG标识对应的TAG为第一类TAG，第一类TAG为包括主小区的TAG。目标服务小区的传输对象不关联PCI标识。
可选地，若第一类TAG失去同步，则释放终端对应的所有上行传输。第一类TAG失去同步，即第一类TAG对应的TAT过期。
在一个实施例中，终端确定目标TAG标识对应的上行时间调整量时，可执行为以下步骤B1-B3：
步骤B1，接收与目标传输对象关联的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，PDCCH携带目标传输对象的对象标识和/或与目标传输对象相关联的目标TAG标识。
终端接收到PDCCH，也就触发了随机接入信道(Random Access CHannel，RACH)流程，从而在RACH过程中接收终端侧设备配置的上行时间调整量。
步骤B2，基于PDCCH，向网络侧设备发送目标传输对象对应的第一信息。第一信息用于确定目标传输对象对应的上行时间调整量。
可选地，网络侧设备基于第一信息确定目标传输对象对应的上行时间调整量，并将上行时间调整量携带于随机接入响应(Random Access Response，RAR)中发送至终端。
其中，第一信息可以是随机信号前导码preamble。网络侧设备通过测量preamble即可确定上行时间调整量。需要说明的是，终端发送给网络侧设备的第一信息不仅仅局限于preamble，还可以是其它任何类型的信息。理论上讲，终端发送的任何信号都可用于测量上行时间调整量，例如信道探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(Demodulation Reference Signal，DM-RS)、信道质量指示(Channel Quality Indicator，CQI)、确认(Acknowledgement，ACK)、非确认(Negative Acknowledgement，NACK)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)等。
步骤B3，接收网络侧设备发送的RAR，并基于RAR确定上行时间调整量。
在一个实施例中，PDCCH对应的准共址(Quasi Co-Location，QCL)关系基于type1公共搜索空间(Common Search Space，CSS)的QCL关系确定，或者，基于与第一type1CSS关联相同传输对象的PDCCH确定。
在一个实施例中，在第一条件下，PDCCH的QCL关系基于PDCCH对应的type1CSS的QCL关系确定。其中，第一条件包括：PDCCH来自不属于主小区的第二服务小区，或者，PDCCH来自主小区的关联PCI对应的第三服务小区。
在一个实施例中，若目标服务小区对应的目标传输对象包括两个，且两个目标传输对象的上行传输时间之间重叠，则终端丢弃两个目标传输对象中的第一传输对象的上行传输。
其中，第一传输对象的上行传输可包括以下至少一项：关联特定控制资源集合池索引(如coresetpoolindex0)的上行传输、上行传输时间较晚的上行传输。
在一个实施例中，终端在丢弃两个目标传输对象中的第一传输对象的上行传输之前，可向网络侧设备上报终端具备针对第一传输对象的上行传输的丢弃能力。
若终端未上报具备针对第一传输对象的上行传输的丢弃能力，则网络侧设备可通过网络调度保证关联不同TAG标识的上行传输不能重叠。可选地，网络侧设备通过网络调度保证关联不同TAG标识的上行传输之间间隔一定时间。例如，关联不同TAG标识的上行传输之间间隔大于或等于预设阈值，该预设阈值可由终端上报给网络侧设备，也可由网络侧设备配置在RRC中，或者还可以基于终端与网络侧设备之间的协议预定义。
本实施例中，若目标服务小区对应的目标传输对象包括两个，则两个目标传输对象的上行传输之间间隔大于或等于预设阈值，该预设阈值可由终端上报给网络侧设备，也可由网络侧设备配置在RRC中，或者还可以基于终端与网络侧设备之间的协议预定义。
下表1示意性地列举了几种子载波间隔下的预设阈值。
表1

其中，FR1(Frequency range 1)、FR2(Frequency range2)表示5G新无线(New Radio，NR)规定的两个频率范围。
可选地，预设阈值还可以是一个正交频分复用(Orthogonal frequency division multiplex，OFDM)符号。
图5是根据本申请另一实施例的一种上行传输时间的确定方法的示意性流程图。如图5所示，该方法应用于网络侧设备，包括以下步骤S502：
S502，向终端发送一个或多个服务小区对应的参数配置信息，参数配置信息包括TAG标识，TAG标识关联有各自的传输对象，参数配置信息用于确定目标服务小区对应的目标传输对象的上行传输时间。
其中，每个TAG标识分别关联一个或多个发送至TRP的传输对象。TAG标识和传输对象之间的关联关系可通过以下几种方式明确。一种方式：在每个服务小区对应的参数配置信息中，每个TAG标识关联有一个或多个发送至TRP的传输对象。另一种方式：服务小区对应的参数配置信息中仅包括TAG标识，网络侧设备通过其它配置信息配置与每个TAG标识关联的传输对象，其中，其它配置信息的配置信息不做限定。再一种方式：服务小区对应的参数配置信息中仅包括TAG标识，并在网络侧设备和终端的通信协议中约定每个TAG标识关联的传输对象。当然，除上述列举的几种方式之外，还可通过其它方式来明确TAG标识和传输对象之间的关联关系，本申请实施例对此不做限定。
本申请实施例中，网络侧设备通过预先配置一个或多个服务小区对应的参数配置信息，并将一个或多个服务小区对应的参数配置信息发送给终端，参数配置信息包括TAG标识，各TAG标识关联有各自的传输对象，使得终端能够根据所在目标服务小区对应的TAG标识，动态确定目标传输对象的上行传输时间，而并非所有的传输对象都采用相同的上行传输时间，且能够确保多TRP的上行传输时间准确，提升上行传输的性能。
在一个实施例中，传输对象包括以下至少一项：资源集合池索引(如coresetpoolindex 0、coresetpoolindex 1)、SRS资源集、TCI状态、TCI状态池、SSB分组、PCI、天线端口组。
在一个实施例中，针对每个服务小区的参数配置信息，可包括以下几种情况：参数配置信息包括两个TAG标识，每个TAG标识分别关联一个上行传输对象；或者，参数配置信息包括一个TAG标识，TAG标识关联两个传输对象；或者，参数配置信息包括一个TAG标识，TAG标识关联一个传输对象。
若网络侧设备配置的参数配置信息中配置了TAG标识与传输对象之间的关联关系，则针对每个服务小区的参数配置信息，TAG标识与传输对象之间的关联关系可以包括以 下a1-a3中的任一种：
a1，参数配置信息包括两个TAG标识和两个传输对象，其中，每个TAG标识分别关联一个上行传输对象。
如图4(a)所示，某一服务小区的参数配置信息中包括两个TAG标识，即TAG0和TAG1，每个TAG标识分别关联一个传输对象，其中，TAG0关联coresetpoolindex0，TAG1关联coresetpoolindex1。
a2，参数配置信息包括一个TAG标识及其关联的两个传输对象。
如图4(b)所示，某一服务小区的参数配置信息中包括一个TAG标识，即TAG0，且TAG0关联两个传输对象，分别是coresetpoolindex0和coresetpoolindex1。
a3，参数配置信息包括一个TAG标识及其关联的一个传输对象。
在一个实施例中，多个服务小区配置有相同的TAG标识，相同的TAG标识关联相同的传输对象相同。
在一个实施例中，每个TAG标识关联一个下行帧时间。
在一个实施例中，针对配置有两个TAG标识的服务小区，网络侧设备指示两个TAG标识中的其中一个TAG标识对应的TAG为第一类TAG；第一类TAG为包括主小区的TAG。
在一个实施例中，网络侧设备指示两个TAG标识中的其中一个TAG标识对应的TAG为第一类TAG时，若传输对象为coresetpoolindex 0，则指示传输对象关联的TAG标识对应的TAG为第一类TAG。
在一个实施例中，网络侧设备向终端发送RRC配置信息，该RRC配置信息携带以下至少一项信息：各服务小区对应的传输对象的DL参考信号或DL信道；第一类TAG的指示信息(即指示哪个TAG标识对应的TAG为第一类TAG)；同一服务小区对应的两个传输对象的上行传输之间间隔的最小阈值，即保证同一服务小区对应的两个传输对象的上行传输之间不能重叠。
在一个实施例中，网络侧设备为每个TAG标识配置相关联的上行时间调整量。具体地，首先，网络侧设备向终端发送与目标传输对象关联的PDCCH，该PDCCH携带目标传输对象的对象标识和/或目标传输对象关联的目标TAG标识，然后，网络侧设备接收终端发送的目标传输对象对应的第一信息，进而根据第一信息确定目标传输对象对应的上行时间调整量，并将上行时间调整量携带于RAR中发送至终端。
其中，第一信息可以是preamble。网络侧设备通过测量preamble即可确定上行时间调整量。需要说明的是，终端发送给网络侧设备的第一信息不仅仅局限于preamble，还可以是其它任何类型的信息。理论上讲，终端发送的任何信号都可用于测量上行时间调整量，例如SRS、DM-RS、CQI、ACK、NACK、PUSCH等。
在一个实施例中，网络侧设备接收终端上报的能力，该能力包括：在服务小区对应的传输对象包括两个、且两个传输对象的上行传输时间之间重叠的情况下，针对第一传输对象的上行传输的丢弃能力。其中，第一传输对象的上行传输为满足丢弃条件的上行传输， 丢弃条件包括以下至少一项：关联特定控制资源集合池索引(如coresetpoolindex 0)、上行传输时间较晚。
图6是根据本申请再一实施例的一种上行传输时间的确定方法的示意性流程图。如图6所示，该方法应用于上行传输时间的确定系统中，该系统包括终端和网络侧设备，包括以下步骤S602-S610：
