可选地,在本申请实施例中的高层参数包括无线资源控制(Radio Resource Control,RRC)信令和媒体接入控制单元(Media Access Control Control Element,MAC CE)中的至少一种。
为了清楚地阐述本申请实施例的思想,首先对本申请实施例的相关技术内容进行简要描述。本申请实施例包括以下内容中的至少部分内容。
在NTN系统或其他传播时延大的通信系统中,终端设备和网络设备的时序关系可能存在两种情况。
情况一:参考图2,基站侧gNB的下行DL时隙与上行UL时隙是对齐的。
在这种情况下,为了使终端侧UE的上行传输和基站侧的上行时隙对齐,UE需要根据定时提前(Timing Advance,TA)值提前传输。传播时延较大,TA也相应较大。由于NR系统的时序关系中,基站侧的下行时隙和上行时隙也是对齐的,因此,可以通过引入偏移参数,参考NR系统中的传输时序确定NTN系统中的传输时序。
情况二:参考图3,基站侧gNB的下行时隙与上行时隙之间存在偏移值TS。
在这种情况下,为了使终端侧UE上行传输和基站侧的上行时隙对齐,UE也需要根据TA值提前传输,TA值相对较小。但这种情况下,基站侧需要复杂的调度方式来处理传输调度时序。
在NTN系统或其他传播时延大的通信系统中,可通过引入偏移参数,来增强终端侧和基站侧的信息传输时序。示例性地,NR系统中的时序关系可以包括以下情形中的一种或多种:
物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的接收时序:当终端设备被下行控制信息(Downlink Control Information,DCI)调度接收PDSCH时,该DCI中包括K 0的指示信息,其中,K 0用于确定传输该PDSCH的时隙。例如,如果在时隙n上收到该调度DCI,则被分配用于PDSCH传输的时隙为时隙
Figure PCTCN2020097266-appb-000001
其中,K 0是根据PDSCH的子载波间隔确定的,μ PDSCH和μ PDCCH分别用于确定为PDSCH和物理下行控制信道(Physical Downlink Control Channel,PDCCH)配置的子载波间隔。K 0的取值范围是0到32。
DCI调度的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的传输时序:当终端设备被DCI调度发送PUSCH时,该DCI中包括K 2的指示信息,其中,K 2用于确定传输该PUSCH的时隙。例如,如果在时隙n上收到该调度DCI,则被分配用于PUSCH传输的时隙为时隙
Figure PCTCN2020097266-appb-000002
其中,K 2是根据PDSCH的子载波间隔确定的,μ PUSCH和μ PDCCH分别用于确定为PUSCH和PDCCH配置的子载波间隔。K 2的取值范围是0到32。
随机接入响应(Random Access Response,RAR)授权grant调度的PUSCH的传输时序:对于被RAR grant调度进行PUSCH传输的时隙,如果终端设备发起物理随机接入信道(Physical Random Access Channel,PRACH)传输后,该终端设备收到包括该对应RAR grant消息的PDSCH的结束位置在时隙n,那么终端设备在时隙n+K 2+Δ上传输该PUSCH,其中,K 2和Δ是协议约定的。
PUCCH上传输混合自动重传请求-应答(Hybrid Automatic Repeat Request-Acknowledgement,HARQ-ACK)的传输时序:对于PUCCH传输的时隙,如果一个PDSCH接收的结束位置在时隙n或一个指示半持续性调度(Semi-Persistent Scheduling,SPS)PDSCH释放的PDCCH接收的结束位置在时隙n,终端设备应在时隙n+K 1内的PUCCH资源上传输对应的HARQ-ACK信息,其中K 1是时隙个数并且是通过DCI格式中PDSCH-to-HARQ-timing-indicator信息域来指示的,或是通过dl-DataToUL-ACK参数提供的。K 1=0对应PUCCH传输的最后一个时隙与PDSCH接收或指示SPS PDSCH释放的PDCCH接收的时隙重叠。
媒体接入控制-控制元素((Media AccessControl-Control Element,MAC-CE)激活时序:当包括MAC-CE命令的PDSCH对应的HARQ-ACK信息在时隙n上传输,该MAC-CE命令指示的对应行为以及终端设备假设的下行配置应从时隙

后的第一个时隙开始生效,其中,

表示子载波间隔配置μ下每个子帧包括的时隙个数。
PUSCH上的信道状态信息(Channel State Information,CSI)传输时序:PUSCH上的CSI传输时序和一般情况下DCI调度PUSCH传输的传输时序相同。
CSI参考资源时序:对于在上行时隙n'上上报CSI的CSI参考资源是根据单个下行时隙n-n CSI_ref确定的,其中,
Figure PCTCN2020097266-appb-000005
μ DL和μ UL分别是下行和上行的子载波间隔配置。n CSI_ref的取值取决于CSI上报的类型。

应理解,在上述时序关系中,不同情形下对应的K offset可以相同,也可以不同,本申请对此并不限定。
实际应用中,网络设备可以向终端设备通知偏移参数值K offset的取值,终端设备接收并确定后可将偏移参数值K offset应用于时序关系中。但是,网络设备如何确定K offset的取值,即如何确定传输时序是本申请亟待解决的技术问题,仍需进一步研究。
为了解决上述技术问题,本申请通过终端设备向网络设备发送指示信息的方式来解决这一技术问题。
图4是根据本申请实施例的无线通信方法400的示意性流程图,该方法400可以应用于如图1所示的通信系统100。具体地,如图4所示,该方法400可以包括如下步骤:
步骤S401:终端设备获取第一指示信息。
步骤S402:终端设备向网络设备发送第一指示信息,第一指示信息用于确定第一传输时序。
可选地,第一传输时序包括以下至少一种:DCI调度的PUSCH的传输时序、RAR grant调度的PUSCH的传输时序、PUCCH上传输HARQ-ACK的传输时序、MAC CE激活时序、PUSCH上的CSI传输时序、CSI参考资源时序、非周期SRS传输时序。
应理解,本申请可以适用于如下场景,但不限于此:
对于终端设备来讲,TA值的获取包括以下方式中的至少一种:
方式一、终端设备根据网络设备指示的第一信息确定TA值。
可选地,网络设备通知的第一信息包括TA值,其中,该TA值包括网络设备为包括上述终端设备在内的多个终端设备配置的公共TA值,即一个公共TA值可以对应一个小区,或者对应一个波束方向,或者对应一个参考信号例如信道状态信息参考信号(Channel state information Reference signal,CSI-RS)索引,或者对应一个同步信号块(Synchronization Signal/Physical Broadcast CHannel Block,SS/PBCH Block或SSB)索引。
这种情况下,终端设备根据第一信息所确定的TA值可以是终端设备相对于上述公共TA值所进行的自行补偿的TA值。
可选地,网络设备通知的第一信息包括卫星速度、角度、定时变化(timing drift)等中的至少一项。
这种情况下,终端设备根据第一信息所确定的TA值可以是终端设备实际补偿的TA值,即包括公共TA值和终端设备自行补偿的TA值。
方式二、终端设备根据自己获取的第二信息确定TA值。
其中,该第二信息包括TA值。
可选地,第二信息包括的TA值是终端设备根据定位信息等已知信息获取的TA值。
这种情况下,终端设备根据第二信息所确定的TA值可以是终端设备实际补偿的TA值,即包括终端设备自行补偿的TA值。
方式三、终端设备根据网络设备通知的第一信息和自行获取的第二信息确定终端设备的TA值。
这种情况下,终端设备根据第一信息和第二信息所确定的TA值可以是终端设备实际补偿的TA 值,即包括公共TA值和终端设备自行补偿的TA值。
应理解,如果偏移参数值K offset是公共值,例如是网络设备针对每个小区或每个波束方向或每个参考信号索引或每个SSB索引配置的,那么对于上述任意一种方式,都不需要终端设备将自行补偿的TA值通知给网络设备。
如果偏移参数值K offset是针对终端设备的专有(UE-specific)值,那么对于上述方式一,由于终端设备的TA补偿是基于网络设备指示的第一信息,因此,网络设备可以自行确定该终端设备的偏移参数值K offset。对于方式二和方式三,由于终端设备自行获取了第二信息,在这种情况下,网络设备在为终端设备确定偏移参数值K offset时,需要终端设备将自行补偿TA值通知给网络设备,以使网络设备可以为终端设备确定偏移参数值K offset。基于此,终端设备需要向网络设备上报第一指示信息。在这种情况下,第一指示信息可以用于指示偏移参数值K offset,该偏移参数值K offset用于确定第一传输时序。
应理解,对于同一个终端设备,不同情况下的K offset值可以不同。例如,RAR grant调度的PUSCH传输对应的K offset值可以是公共值,连接态的UL grant例如DCI格式0_1调度的PUSCH传输对应的K offset值可以是终端设备专有值。又例如,DCI格式0_0调度的PUSCH传输对应的K offset值可以是公共值,DCI格式0_1调度的PUSCH传输对应的K offset值可以是终端设备专有值。
应理解,在其他场景下,可能也需要终端设备向网络设备上报上述第一指示信息,例如终端设备根据下行测量确定进行小区切换或波束切换或传输配置指示(Transmission Configuration Indication,TCI)状态(state)切换等。并且上述第一指示信息也不限定于用于指示偏移参数值K offset
