Description

定时提前确定方法及相关装置

背景技术
目前，对于一个用户，一个主小区组(master cell group，MCG)或一个辅小区组(secondary cell group，SCG)可以配置关联多达四个定时提前组(timing advance group，TAG)，TAG是指与该TAG关联的一个或多个小区的定时提前值(TA)是相同的。每个小区的TA用于该小区的物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)以及信道探测参考信号(sounding reference signal，SRS)等上行信号或信道的定时提前。从而使得该小区覆盖下的终端设备发送的上行信号或信道能够同时到达网络设备。
然而，基于多下行控制信息(downlink control information，DCI)的多个传输点(transmission and reception point，TRP)的传输，简称M-DCI based M-TRP传输，M-TRP属于同一个小区，但由于多个TRP的位置不同，因此若采用同一个TA，会影响上行信号或信道的对齐效果。

需要说明的是，本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，对此不做任何限定。本申请实施例中出现的“网络”与“系统”表达的是同一概念，通信系统即为通信网络。

随着通信技术的发展，无线通信系统不仅可以支持传统的无线通信系统，还可以支持如设备到设备(device to device，D2D)通信、机器到机器(machine to machine，M2M)通信、机器类型通信(machine type communication，MTC)、车辆间(vehicle to vehicle，V2V)通信、车联网(vehicle to everything，V2X)通信、窄带物联网(narrow band internet of things，NB-IoT)通信等，因此本申请实施例的技术方案也可以应用于上述无线通信系统。
例如，请参阅图1，图1是本申请实施例提供的一种通信系统的结构示意图。如图1所示，该通信系统包括可不限于网络设备101、网络设备102，其中，该图1所示的通信系统以M-DCI based M-TRP传输为例，即网络设备101和网络 设备102均能够为终端设备提供服务。
具体的，终端设备可以是用户设备(user equipment，UE)、远程/远端终端设备(remote UE)、中继设备(relay UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、移动设备、用户终端设备、智能终端设备、无线通信设备、用户代理或用户装置。需要说明的是，中继设备是能够为其他终端设备(包括远程终端设备)提供中继转发服务的终端设备。另外，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、个人数字助理(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、下一代通信系统(例如NR通信系统)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，对此不作具体限定。
进一步的，终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；可以部署在水面上(如轮船等)；还可以部署在空中(如飞机、气球和卫星等)。
进一步的，终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人自动驾驶中的无线终端设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备或者智慧家庭(smart home)中的无线终端设备等。
进一步的，终端设备可以包括具有收发功能的装置，例如，芯片系统。其中，芯片系统可以包括芯片，还可以包括其它分立器件。
网络设备可以是用于与终端设备之间进行通信的设备，其负责空口侧的无线资源管理(radio resource management，RRM)、服务质量(quality of service，QoS)管理、数据压缩和加密、数据收发等。其中，网络设备可以是通信系统中的基站(base station，BS)或者部署于无线接入网(radio access network，RAN)以用于提供无线通信功能的设备。例如，GSM或CDMA通信系统中的基站(base transceiver station，BTS)、WCDMA通信系统中的节点B(node B，NB)、LTE 通信系统中的演进型节点B(evolutional node B，eNB或eNodeB)、NR通信系统中的下一代演进型的节点B(next generation evolved node B，ng-eNB)、NR通信系统中的下一代节点B(next generation node B，gNB)、双链接架构中的主节点(master node，MN)、双链接架构中的第二节点或辅节点(secondary node，SN)等，对此不作具体限制。

进一步的，网络设备可以与互联网协议(Internet Protocol，IP)网络进行通信。例如，因特网(internet)、私有的IP网或者其他数据网等。
需要说明的是，在一些网络部署中，网络设备可以是一个独立的节点以实现上述基站的所有功能，其可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，如gNB-CU和gNB-DU；还可以包括有源天线单元(active antenna unit，AAU)。其中，CU可以实现网络设备的部分功能，而DU也可以实现网络设备的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)层、服务数据适配(service data adaptation protocol，SDAP)层、分组数据汇聚(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。另外，AAU可以实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者由PHY层的信息转变而来，因此，在该网络部署下，高层信令(如RRC层信令)可以认为是由DU发送的，或者由DU和AAU共同发送的。可以理解的是，网络设备可以包括CU、DU、AAU中的至少一个。另外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网中的网络设备，对此不做具体限定。
目前，M-DCI based M-TRP传输中，M-TRP属于同一个小区，由于多个TRP的位置不同，因此若采用同一个TA，会影响上行信号或信道的对齐效果，进而影响系统性能。
本申请提供一种定时提前确定方法100，该方法中，网络设备可向终端设备发送资源配置信息，其中，资源配置信息用于配置上行信号或上行信道的资源与各TAG之间的关联关系；终端设备根据上行信号或上行信道的资源与各TAG之间的关联关系，可获知每个上行信号或上行信道的TA值，从而实现针对每个TRP的TA增强，进而提升上行信号或上行信道的对齐效果。
本申请提供一种定时提前确定方法200，该方法中，网络设备可向终端设备发送资源配置信息，资源配置信息用于配置上行信号或上行信道的资源与控制资源集合池索引CORESETPoolIndex之间的关联关系；由于终端设备可获知CORESETPoolIndex与TAG之间的关联关系，故终端设备根据CORESETPoolIndex与TAG之间的关联关系、CORESETPoolIndex与上行信号或上行信道的资源之间的关联关系，即可获知上行信号或上行信道的资源与TAG之间的关联关系，从而能够确定每个上行信号或上行信道的TA值，实现针对每个TRP的TA增强，进而提升上行信号或上行信道的对齐效果。
为便于理解本申请实施例，此处对本申请可能涉及的一些术语或概念进行阐述。
1、定时提前
定时提前是终端设备针对上行子帧的发送边界相对于下行帧的接收边界提前一定时长，该一定时长的大小可称为TA值。网络设备基于TA控制每个终端设备的该TA值，控制来自不同终端设备的上行信号或上行信道到达网络设备的时间，使得来自不同终端设备的上行信号或上行信道到达网络设备的时间基本上是对齐的。
例如，请参阅图2，图2是本申请实施例提供的一种定时提前的示意图，如图2所示，终端设备针对上行子帧的发送边界相对于下行子帧的接收边界提前时长TA发送上行信号或上行信道，上行信号或上行信道经过传播时延TA/2后，到达网络设备的时间与下行子帧的帧边界是对齐的。
2、定时提前组
TAG是指与该TAG关联的1个或多个小区的TA是相同的，即这里的组是针对多个小区的，该多个小区的TA相同，可称为该多个小区关联同一个TAG。本申请中，每个TAG具有TAG标识，故关联关系中，与一个TAG关联，也可理解为与一个TAG标识关联。
3、资源配置信息
一种可选的实施方式中，资源配置信息用于配置上行信号或上行信道的资源与各TAG之间的关联关系。
另一种可选的实施方式中，资源配置信息用于配置上行信号或上行信道的资源与CORESETPoolIndex之间的关联关系。在现有的协议中，可以认为一个控制资源集合池索引(CORESETPoolIndex)关联于一个TRP，不同的控制资源集合池索引关联于不同的TRP，如CORESETPoolIndex＝0关联于一个TRP，CORESETPoolIndex＝1关联于另一个TRP。换句话说，如果信号或者信道，关联于某个控制资源集合池索引，则可以认为此信号或者信道关联于此控制资源集合池索引关联的TRP，也即此信号或者信道是来自于此TRP的发送，或者面向此TRP发送。该实施方式中，资源配置信息用于配置上行信号或上行信道的资源与CORESETPoolIndex之间的关联关系，故终端可获知各上行信号或上行信道的资源与各TRP之间的关联关系。
其中，资源配置信息是通过无线资源控制(radio resource control，RRC)配置的，或是通过媒体接入控制-控制元素(medium access control-control element，MAC-CE)配置的。
以下结合附图对本申请实施例进行进一步的阐述。
请参阅图3，图3是本申请实施例提供的一种定时提前确定方法100的流程示意图。如图3所示，该定时提前确定方法100包括但不限于以下步骤：
S101、网络设备确定上行信号或上行信道的资源配置信息；
S102、网络设备向终端设备发送资源配置信息，相应的，终端设备接收该资源配置信息；
由于资源配置信息中需配置上行信号或所述上行信道的资源与各TAG之间的关联关系。故网络设备需要确定针对每个TRP的上行信号或上行信道的TA，进而根据针对每个TRP的上行信号或上行信道的TA，确定资源配置信息中各上行信号或上行信道的资源与各TAG之间的关联关系。
S103、终端设备根据资源配置信息，确定上行信道或上行信号的定时提前TA。
终端根据资源配置信息中配置的各上行信号或上行信道的资源与各TAG之 间的关联关系，可获得每个上行信号或上行信道的TA。
可见，通过资源配置信息中上行信号或上行信道的资源与各TAG之间的关联关系，能够实现针对每个TRP的TA增强，进而提升上行信号或上行信道的对齐效果。
本申请实施例还提供一种定时提前确定方法200，该定时提前确定方法200与上述定时提前确定方法100的不同之处在于，资源配置信息用于配置上行信号或上行信道的资源与CORESETPoolIndex之间的关联关系。
由于终端设备可获知CORESETPoolIndex与各TAG之间的关联关系，故终端设备根据该方法中的资源配置信息可以确定上行信号或上行信道的资源与各TAG之间的关联关系，从而能够确定每个上行信号或上行信道的TA值。可见，通过资源配置信息中上行信号或上行信道的资源与各CORESETPoolIndex之间的关联关系，能够实现针对每个TRP的TA增强，进而提升上行信号或上行信道的对齐效果。
可选的，该定时提前确定方法200中，CORESETPoolIndex与各TAG之间存在关联关系，且CORESETPoolIndex与各TAG之间的关联关系是预定义的或是网络设备为终端设备配置的，如采用RRC或MAC-CE的方式配置的。
以下对该定时提前确定方法100、定时提前确定方法200包括但不限于的可选的实施方式进行阐述。
一种可选的实施方式中，上行信道是周期性的物理上行控制信道PUCCH或半持续调度的物理上行控制信道PUCCH。
也就是说，在定时提前确定方法100中，对于周期性的PUCCH或者半持续调度的PUCCH，网络设备可通过RRC或者MAC-CE配置其关联的TAG，进而获得其TA值。
在定时提前确定方法200中，对于周期性的PUCCH或者半持续调度的PUCCH，网络设备可通过RRC或者MAC-CE配置其关联的CORESETPoolIndex。进而终端设备基于CORESETPoolIndex与TAG之间的关联关系，确定周期性的PUCCH或者半持续调度的PUCCH所关联的TAG，进而获得其TA值。
而对于下行控制信息(downlink control information，DCI)触发的PUCCH， PUCCH所关联的TRP或者CORESETPoolIndex，与承载此DCI的PDCCH所关联的TRP或者CORESETPoolIndex一致，进而即可获知PUCCH所关联的TAG。同理，对于DCI触发的PUSCH，PUSCH所关联的TRP或者CORESETPoolIndex，与承载此DCI的PDCCH所关联的TRP或者CORESETPoolIndex一致，终端设备同样可获知PUSCH所关联的TAG，进而获得其TA值。
一种可选的实施方式中，上行信道是配置授权类型1的物理上行共享信道PUSCH。
也就是说，在定时提前确定方法200，对于配置授权类型1的PUSCH，网络设备可通过RRC或者MAC-CE配置其关联的TAG，进而获得其TA值。
在定时提前确定方法200，对于配置授权类型1的PUSCH，网络设备可通过RRC或者MAC-CE配置其关联的CORESETPoolIndex，进而终端设备基于CORESETPoolIndex与各TAG之间的关联关系，确定周期性的PUCCH或者半持续调度的PUCCH所关联的TAG，进而获得其TA值。
一种可选的实施方式中，上行信号是信道探测参考信号(Sounding reference signal，SRS)。
也就是说，在定时提前确定方法100，对于SRS，网络设备可通过RRC或者MAC CE配置其关联的TAG，进而获得其TA值。
在定时提前确定方法200，对于SRS，网络设备可通过RRC或者MAC CE配置其关联的CORESETPoolIndex，进而终端设备可获知SRS所关联的TAG，进而获得其TA值。可选地，SRS可以是周期性或者持续调度的SRS。
一种可选的实施方式中，针对定时提前确定方法100，上行信号或上行信道的资源关联的是服务小区的第二个TAG或标识最小的TAG或第一个TAG或标识最大的TAG。其中，该服务小区是该终端设备驻留的小区。一个小区可关联多个TAG，该实施方式可明确终端设备可使用的一个TAG。
一种可选的实施方式中，针对定时提前确定方法200，上行信号或上行信道的资源关联的控制资源集合池CORESETPoolIndex取值等于第一值。该第一值可为0或1，即CORESETPoolIndex＝0，或者，CORESETPoolIndex＝1。
请参阅图4，图4是本申请实施例的一种定时提前确定装置的结构示意图。其中，定时提前确定装置400包括处理器410、存储器420以及用于连接处理器 410、存储器420的通信总线。
存储器420包括但不限于是随机存储记忆体(random access memory，RAM)、只读存储器(read-only memory，ROM)、可擦除可编程只读存储器(erasable programmable read-only memory，EPROM)或便携式只读存储器(compact disc read-only memory，CD-ROM)，该存储器420用于存储定时提前确定装置400所执行的程序代码和所传输的数据。
定时提前确定装置400还可以包括通信接口，其可以用于接收和发送数据。
处理器410可以是一个或多个CPU，在处理器410是一个CPU的情况下，该CPU可以是单核CPU，也可以是多核CPU。
