应理解,本申请中的通信设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现,或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
上行数据传输
在一些通信系统(例如NR系统)中,上行数据传输承载于PUSCH。PUSCH的传输可以包括基于上行授权(UL grant)调度的PUSCH传输和基于免授权(configured grant,CG)的PUSCH传输。上行授权调度可以通过下行控制信息(downlink control information,DCI)格式(format)0_0或DCI格式0_1承载。或者,上行授权调度可以通过随机接入响应(random access response,RAR)承载。
对于承载上行授权的DCI,网络设备可以在DCI中携带一个时间域资源分配(TimeDomainResourceAllocation,TDRA)的域。TDRA域可以指示一个资源分配表格中的不同的行。资源分配表格中每一行可以包含不同的资源分配组合。资源分配组合可以包括:PUSCH的起始位置S,长度L,k2以及不同的类型(type)中的一个或多个。其中,k2可以表示DCI所在的时隙(slot)和PUSCH所在的时隙之间的偏移时隙的个数。TDRA域可以为4bit,从而可以指示资源分配表格中的16个不同的行。另外,DCI也可以指示PUSCH的频域资源分配信息、调制编码方式(modulation and coding scheme,MCS)、新数据指示(new data indicator,NDI)、冗余版本以及混合自动重传请求(hybrid automatic repeat request,HARQ)进程号等信息中的一个或多个。
上行授权的RAR可以用于承载随机接入过程中的PUSCH。在一些通信系统(例如NR系统或LTE系统)中,随机接入过程可以采用四步过程,即消息1(Msg1)至消息4(Msg4)的发送过程。其中,消息1(Msg3)可以通过PUSCH承载,用于承载Msg3初次传输的PUSCH的上行授权可以通过消息2(Msg2)中的RAR承载。RAR上行授权信息可以如表1所示。RAR上行授权信息可以包括PUSCH的时域和频域资源分配信息、功率控制命令(transmit power control,TPC)、跳频以及MCS等信息中的一个或多个。
表1
如果网络设备没有收到终端设备发送的Msg3,可以通过DCI指示Msg3的重传的调度信息。例如,可以通过临时小区无线网络临时标识(temporary cell radio network temporary identity,TC-RNTI)加扰的DCI format 0_0承载。DCI中不仅可以包含RAR上行授权的内容,也可以包括NDI、冗余版本以及 HARQ进程号。
PUSCH的MCS表格的确定
数据传输需要配置合适的调制编码以适应信道质量变化,并满足业务可靠性需求。例如,URLLC与eMBB的评估场景和覆盖需求相同,但URLLC的可靠性需求更高。因此,针对eMBB设计的MCS表格无法匹配URLLC高可靠性传输。为了适应URLLC业务的需要,通信系统可以支持MCS表格的半静态配置和动态指示。其中,半静态配置可以基于RRC信令实现,动态指示可以基于PDCCH信道实现。
可以理解的是,为了支持URLLC业务的高可靠性和低时延,可以牺牲一定的频谱效率。因此,URLLC业务对应的MCS表低频谱效率64qam(qam64LowSE)对应的频谱效率的范围与eMBB业务对应的MCS表格qam256是不同的。qam64LowSE在qam256的基础上补充了相应低频谱效率对应的MCS元素,并且删除了高频谱效率对应的MCS元素。不同MCS表格的选择可以通过结合RRC信令的配置和加扰DCI的循环冗余校验(cyclic redundancy check,CRC)的RNTI来确定。
作为一种实现方式,可针对MCS表格选择设置调制和编码方案小区无线网络临时标识(modulation and coding scheme cell radio network temporary identity,MCS-C-RNTI)。如果MCS-C-RNTI没有被配置,或者调度PUSCH传输的PDCCH的CRC通过小区无线网络临时标识(cell radio network temporary identity,C-RNTI)、半静态信道状态信息无线网络临时标识(semi persistent channel state information radio network temporary identity,SP-CSI-RNTI)或设定调度无线网络临时标识(configured scheduling radio network temporary identity,CS-RNTI)加扰,或者PUSCH基于免调度传输,则终端设备可以使用通过RRC参数mcs-Table和mcs-TableTransformPrecoder半静态配置的MCS表格。当MCS表格qam256被配置,则PUSCH的传输可以使用MCS表格qam256。当MCS表格qam64LowSE被配置,则PUSCH的传输可以使用MCS表格qam64LowSE。如果配置了MCS-C-RNTI,并且调度PUSCH的PDCCH的CRC通过MCS-C-RNTI加扰,则PUSCH的传输可以采用MCS表格qam64LowSE。
需要说明的是,上述实现方式可以适用于DCI format 0_1/0_2调度的PUSCH。对于公共搜索空间的DCI format 0_0调度的PUSCH,PUSCH的传输可以沿用现有的MCS表格。
上行传输的波形
用于数据传输的波形可以包括离散傅里叶变换拓展正交频分复用(discrete fourier transform spread orthogonal frequency division multiplexing)DFT-S-OFDM波形以及循环前缀正交频分复用(cyclic prefix orthogonal frequency division multiplexing,CP-OFDM)波形等。DFT-S-OFDM波形可以具有更低的峰均功率比(peak-to-average power ratio,PAPR),也可以实现更好的覆盖。DFT-S-OFDM波形可以用于覆盖受限的场景。CP-OFDM波形可以支持更加灵活的数据调度。CP-OFDM波形可以用于覆盖不受限的场景。
在一些通信系统(例如LTE系统)中,下行传输的波形可以支持CP-OFDM波形,上行传输的波形(即传输PUSCH的波形)仅支持DFT-S-OFDM的波形。在一些通信系统(例如NR系统)中,上行传输的波形也可以支持CP-OFDM的波形,从而支持更加灵活的数据调度。其中,CP-OFDM的波形可以与下行波形相同。上行波形可以从CP-OFDM以及DFT-S-OFDM中选择。
上行波形可以通过变换预编码(transform precoder)的使能和去使能来指示。其中,变换预编码使能可以对应DFT-S-OFDM波形,变换预编码去使能可以对应CP-OFDM波形。
上行波形可以通过RRC参数半静态配置。例如,上行波形可以通过以下任意一个或多个RRC参数进行配置:PUSCH-Config中配置的参数transformPrecoder、RACH-ConfigCommon中配置的参数msg3-transformPrecoder、ConfiguredGrantConfig中配置的参数transformPrecoder以及MsgA-PUSCH-Config中配置的参数msgA-TransformPrecoder-r16。PUSCH-Config.transformPrecoder可以用于配置终端设备特定的PUSCH传输的波形。RACH-ConfigCommon.msg3-transformPrecoder可以用于配置Msg3的PUSCH传输的波形。ConfiguredGrantConfig.transformPrecoder可以用于配置免调度PUSCH传输的波形。MsgA-PUSCH-Config.msgA-TransformPrecoder-r16可以用于配置消息A(MsgA)的PUSCH传输的波形。
由上文可知,传输PUSCH的波形可以通过RRC信令实现半静态配置。由于半静态配置的灵活性较弱,难以根据实际通信场景快速切换传输PUSCH的波形,从而导致PUSCH的覆盖性能难以与变化的通信场景匹配。相关技术(例如R18标准)提出了PUSCH的波形动态切换的需求,但是并未提出如何实现传输PUSCH波形的动态指示。
针对上述情况,本申请提出通过调度PUSCH的PDCCH指示该PUSCH的变换预编码的使能状态。也就是说,PUSCH的变换预编码的使能状态可以通过调度该PUSCH的PDCCH指示。不同的变换预编码使能状态可以对应不同的PUSCH波形,从而实现PUSCH波形的动态指示。
作为一个实施例,网络设备可以基于实际通信情况确定变换预编码的使能状态。例如,在动态的上 行调度过程中,网络设备可以根据以下信息中的一项或多项确定变换预编码的使能状态:PUSCH的接收信噪比、解调参考符号(demodulation reference symbol,DMRS)的接收信噪比、PUSCH的误码率、信道探测参考信号(sounding reference signal,SRS)的测量结果以及功率余量上报(power headroom report,PHR)的结果。
网络设备确定变换预编码的使能状态后,可以根据变换预编码的使能状态传输调度PUSCH的PDCCH,从而动态地指示该PUSCH的变换预编码的使能状态。
终端设备可以通过接收到的调度PUSCH的PDCCH,确定PUSCH的变换预编码的使能状态。为便于描述,下文将PUSCH的变换预编码简称为变换预编码。
预编码的使能状态可以包括第一状态或第二状态。
第一状态可以为使能,也可以为去使能。第一状态可以是预定义的。例如,第一状态可以预定义为去使能。第一状态也可以为网络设备配置的。例如,第一状态可以为RRC信令半静态配置的变换预编码的使能状态。RRC半静态配置的变换预编码的使能状态可以包括PUSCH-Config中配置的transformprecoder、ConfiguredGrantConfig中配置的transformprecoder、MsgA-PUSCH-Config中配置的msgA-TransformPrecoder或者RACH-ConfigCommon中配置的msg3-transformPrecoder。
第二状态可以为使能,也可以为去使能。第二状态可以为与第一状态不同的变换预编码使能状态。例如,第一状态为使能的情况下,第二状态可以为去使能。或者,第一状态为去使能的情况下,第二状态可以为使能。第二状态可以是预定义的。第二状态也可以是基于网络设备配置的。例如,第二状态可以是与RRC信令半静态配置的变换预编码的使能状态不同的使能状态。在一些实施例中,第二状态也可以称为目标变换预编码的使能状态。
需要说明的是,在一些实施例中,去使能也可以称为去使能状态,使能也可以称为使能状态。作为一种实现方式,可以通过调度PUSCH的PDCCH所加扰的RNTI指示变换预编码的使能状态。可以理解的是,PDCCH可以包括一个或多个校验比特。部分或全部的校验比特例如可以使用CRC的方式进行校验。加扰PDCCH的RNTI可以为加扰所述部分或全部校验比特的RNTI。
在一个实施例中,可以通过加扰调度PUSCH的PDCCH的RNTI,指示变换预编码的使能状态。例如,可以通过加扰所述PDCCH的RNTI类型,指示变换预编码的使能状态。
作为一种实现方式,不同的RNTI类型可以对应不同的变换预编码使能状态。例如,RNTI的类型可以包括第一RNTI类型或第二RNTI类型。第一RNTI类型可以用于指示变换预编码的使能状态为第一状态,第二RNTI类型可以用于指示变换预编码的使能状态为第二状态。
作为另一种实现方式,特定的RNTI类型可以用于指示PUSCH的变换预编码使能状态的切换或改变。例如,RNTI的类型可以包括第二RNTI类型。第二RNTI类型可以用于指示变换预编码使能状态的切换。以RNTI的类型还包括第一RNTI类型为例,第一RNTI类型可以用于指示不改变变换预编码的使能状态,即预编码使能状态保持为当前预编码使能状态。第二RNTI类型可以用于指示将预编码使能状态切换为与当前预编码使能状态不同的使能状态。例如,第二RNTI类型可以用于指示将预编码使能状态由使能切换为去使能,或由去使能切换为使能。
第一RNTI类型或第二RNTI类型可以包括一个或多个RNTI。第一RNTI类型可以包括相关技术中已有的RNTI。例如,第一RNTI类型可以包括MCS-C-RNTI、C-RNTI、SP-CSI-RNTI或CS-RNTI。第二RNTI类型可以包括相关技术中已有的RNTI,也可以包括新定义的一个RNTI。例如,第二RNTI类型包括一个新定义的RNTI,该新定义的RNTI可以命名为变换预编码小区无线网络临时标识(transform precoder cell radio network temporary identity,TP-C-RNTI)。在终端设备接收PDCCH时,终端设备可以对第一RNTI类型和第二RNTI类型进行尝试,从而确定对PDCCH的CRC加扰的RNTI类型,进而确定变换预编码的使能状态并使用对应的波形传输PUSCH。
图2为本申请实施例提供的一种动态指示变换预编码使能状态的过程示例图。在图2所示的实施例中,第一RNTI类型可以包括C-RNTI,第二RNTI类型可以包括TP-C-RNTI,第一状态可以为去使能状态,第二状态可以为使能状态。
图2所示的实施例中,用于调度PUSCH的DCI所示的时隙和PUSCH所在的时隙之间的偏移为2个时隙。下行时隙211中的DCI可以用于调度上行时隙221的PUSCH。下行时隙212中的DCI可以用于调度上行时隙222的PUSCH。在下行时隙211上,DCI可以通过TP-C-RNTI加扰,则在上行时隙221上,上行变换预编码的使能状态可以为使能状态,即PUSCH可以通过DFT-S-OFDM波形传输。在下行时隙212上,DCI可以通过C-RNTI加扰,则在上行时隙222上,上行变换预编码的使能状态可以为去使能状态,即PUSCH可以通过CP-OFDM波形传输。
本申请通过调度PUSCH的PDCCH的CRC所加扰的RNTI类型指示变换预编码的使能状态,可以在不改变现有的DCI格式的前提下,实现变换预编码使能状态的动态指示,从而实现传输PUSCH的波 形的动态切换。
需要说明的是,第二RNTI类型可以通过网络设备配置。例如,第二RNTI类型可以通过信令物理小区组配置(PhysicalCellGroupConfig)配置。例如,可以在PhysicalCellGroupConfig配置增加TP-C-RNTI的信息元素。
RRC信令半静态配置变换预编码的使能状态可以与PDCCH的CRC的RNTI类型实现变换预编码的使能状态的动态切换相结合,从而实现变换预编码使能状态的半静态配置和动态配置。可以理解的是,在这种情况下,第一状态可以为RRC信令配置的变换预编码的使能状态。
作为一个实施例,如果第二RNTI类型(例如TP-C-RNTI)没有被配置,或者调PUSCH传输的PDCCH的CRC通过第一RNTI类型(例如MCS-C-RNTI、C-RNTI、SP-CSI-RNTI或CS-RNTI)加扰,或者PUSCH基于免调度传输,则变换预编码的使能状态可以为第一状态。第一状态可以为RRC半静态配置的变换预编码的使能状态。
作为另一个实施例,如果配置了第二RNTI类型,并且调度PUSCH的PDCCH的CRC通过第二RNTI加扰,则变换预编码可以为第二状态。第二状态可以是预定义的状态,也可以是基于网络配置的状态。第二状态可以包括使能或去使能状态。作为一种实现方式,第二状态可以是与RRC信令半静态配置的变换预编码的使能状态不同的使能状态。
本申请还提出通过加扰PDCCH的RNTI类型动态指示变换预编码的使能状态与MCS表格两种信息。不同的RNTI类型可以对应不同的变换预编码使能状态和MCS表格的组合。RNTI的类型可以包括一个或多个RNTI。RNTI类型可以包括相关技术中已有的RNTI,也可以包括新定义的RNTI。
作为一种实现方式,RNTI的类型可以包括第一RNTI类型、第二RNTI类型、第三RNTI类型或第四RNTI类型。第一RNTI类型可以用于指示变换预编码的使能状态为第一状态且MCS表格为第一表格;第二RNTI类型可以用于指示变换预编码的使能状态为第二状态且MCS表格为第一表格;第三RNTI类型可以用于指示变换预编码的使能状态为第二状态且MCS表格为第二表格;第四RNTI类型可以用于指示变换预编码的使能状态为第一状态且MCS表格可以为第二表格。

需要说明的是,上述一个或多个RNTI类型(例如上文所述的第二RNTI类型、第三RNTI类型或第四RNTI类型)可以通过信令PhysicalCellGroupConfig配置。例如,可以在PhysicalCellGroupConfig中增加用于配置新定义的RNTI的信息元素。
上文详细说明了通过调度PUSCH的PDCCH的CRC的RNTI指示变换预编码的使能状态。本申请还提供其他实施例以实现动态指示变换预编码的使能状态。例如,可以通过调度PUSCH的PDCCH的搜索空间集合、监听时机或DCI格式隐含指示变换预编码的使能状态。
作为一种实现方式,可以通过调度PUSCH的PDCCH的搜索空间集合指示变换预编码的使能状态。
终端设备可以被配置至少两种调度PDCCH的搜索空间集合。网络设备可以根据待指示的变换预编码的使能状态确定搜索空间集合。终端设备接收PDCCH时,可以确定PDCCH的搜索空间集合,从而确定变换预编码的使能状态。
PDCCH的搜索空间集合可以属于多个空间集合中的一个。例如,PDCCH的搜索空间集合可以属于第一搜索空间集合或第二搜索空间集合。第一搜索空间集合可以用于指示变换预编码的使能状态可以为第一状态。第二搜索空间集合可以用于变化预编码的使能状态可以为第二状态。其中,第一搜索空间集合可以为公共搜索空间集合,第二搜索空间集合可以为终端设备专用的搜索空间集合。或者,第一搜索空间集合可以为终端设备专用的搜索空间集合,第二搜索空间集合可以为公共搜索空间集合。
作为另一种实现方式,可以通过调度PDCCH的搜索空间集合中的监听时机指示变换预编码的使能状态。
PDCCH的搜索空间集合可以包含PDCCH的监听时机。监听时机可以属于一个或多个监听时机集合。一个或多个监听时机集合可以对应相应的转换预编码的使能状态。网络设备可以确定PDCCH的监听时机所属的监听时机集合,以指示转换预编码的使能状态。终端设备可以确定PDCCH的监听时机所属的监听时机集合并确定转换预编码的使能状态。
监听时机集合可以包括一个或多个监听时机集合。例如,一个或多个监听时机集合可以包括第一监听时机集合和第二监听时机集合。在调度PUSCH的PDCCH的监听时机属于第一监听时机集合的情况下,转换预编码的使能状态可以为第一状态,在调度PUSCH的PSCCH的监听时机属于第二监听时机 集合的情况下,转换预编码的使能状态可以为第二状态。
作为再一种实现方式,可以通过DCI的格式指示预编码变换的使能状态。
终端设备可以被配置至少两种DCI格式。网络设备可以根据待指示的变换预编码的使能状态确定DCI格式。终端设备可以根据检测到的PDCCH的DCI格式,确定变换预编码的使能状态。
例如,DCI的格式可以包括第一格式以及第二格式。在DCI格式为第一格式的情况下,变换预编码的使能状态可以为第一状态。在DCI格式为第二格式的情况下,变换预编码的使能状态可以为第二状态。其中,第一格式可以为一种或多种DCI格式中的一个,第二格式可以为一种或多种DCI格式中的一个。
图3为本申请实施例提供的一种动态指示变换预编码使能状态的过程示例图。在图3所示的实施例中,第一状态可以为变换预编码使能,第二状态可以为变换预编码去使能。
图3所示的实施例中,用于调度PUSCH的DCI所示的时隙和PUSCH所在的时隙之间的偏移为2个时隙。下行时隙311中的DCI可以用于调度上行时隙321的PUSCH。下行时隙312中的DCI可以用于调度上行时隙322的PUSCH。在下行时隙311上,PDCCH所述的搜索空间集合属于第一搜索空间集合,或PDCCH的监听时机属于第一监听时机集合,或DCI格式为第一格式,则在上行时隙321上,上行变换预编码的使能状态可以为使能状态,即PUSCH可以通过DFT-S-OFDM波形传输。在下行时隙312上,PDCCH所述的搜索空间集合属于第二搜索空间集合,或PDCCH的监听时机属于第二监听时机集合,或DCI格式为第二格式,则在上行时隙322上,上行变换预编码的使能状态可以为去使能状态,即PUSCH可以通过CP-OFDM波形传输。
通过调度PUSCH的PDCCH的搜索空间集合、监听时机或DCI格式隐含指示变换预编码的使能状态可以减少PDCCH检测虚警概率。
需要说明的是,调度PUSCH的PDCCH的搜索空间集合、监听时机集合或DCI格式可以和调度PUSCH的PDCCH的CRC的RNTI类型结合,指示变换预编码的使能状态。例如,公共搜索空间集合可以用于指示变换预编码的使能状态为第一状态,终端设备专用的搜索空间集合可以用于指示变换预编码的使能状态为第二状态。并且,在终端设备专用的搜索空间中,第一RNTI类型可以用于指示变化预编码的使能状态为第一状态,第二RNTI类型可以用于指示变换预编码的使能状态为第二状态。
需要说明的是,网络设备可以为终端设备配置是否开启变换预编码动态切换。例如,网络设备可以向终端设备发送第一信息。第一信息可以用于指示所述终端设备根据调度PUSCH的PDCCH确定PUSCH的变换预编码的使能状态,即开启变换预编码动态切换。
需要说明的是,终端设备可以向网络设备上报终端设备是否具有变换预编码动态切换的相关能力。例如,终端设备可以向网络设备发送第一终端能力。第一终端能力可以用于指示终端设备是否支持动态确定PUSCH的变换预编码的使能状态,即终端设备是否具有变换预编码动态的切换能力。可以理解的是,在网络设备为终端设备配置是否开启变换预编码动态切换之前,可以上报终端设备是否支持动态确定PUSCH的变换预编码的使能状态。
