在时分双工(Time domain duplex,TDD)系统中,为了降低网络设备的实现复杂度,一个TDD载波的所有频域资源在同一时刻的传输方向需相同,即同为上行或下行,使得一个TDD载波不同频域资源的上、下行时隙配比不能灵活配置。随着业务的多元化,单一的上、下行时隙配比不能满足不同业务的需求。基于此,提出了在同一载波的不同子带采用不同的上、下行时隙配比的子带全双工(Subband Full Duplex,SBFD)的解决方案。而针对如何确定SBFD资源内用于进行传输的频域资源,还需进一步研究。

初始BWP用于终端设备执行初始接入流程,其中,包括剩余最小系统信息(remaining minimum system information,RMSI)、控制资源集(Control Resource Set,CORESET)和RMSI频率位置、带宽、子载波间隔(Subcarrier Spacing,SCS)等参数。初始BWP由网络设备通过物理广播信道(Physical Broadcast Channel,PBCH)下发给终端设备。终端设备采用从系统信息中接收到的初始BWP来进行初始接入,直到在小区中接收到终端设备的配置信息为止。其中,初始BWP可以是初始上行BWP(initial UL BWP),初始上行BWP可用于终端设备进行上行传输。
激活BWP为特定于终端设备的BWP,也可以用于执行初始接入过程。激活BWP是在无线资源控制(Radio Resource Control,RRC)配置或重新配置后,终端设备开始传输数据的第一个BWP。每个时刻下行链路(Down Link,DL)和上行链路(UpLink,UL)都只有一个激活BWP。终端设备在激活BWP内采用相关参数集进行收发工作。其中,激活BWP可以是激活上行BWP(active UL BWP),激活上行BWP可用于终端设备进行上行传输。
其中,如果配置了物理随机接入信道(Physical Random Access Channel,PRACH)资源,则终端设备不能在激活BWP之外传输PRACH资源;如果没有配置PRACH资源,则终端设备使用初始上行BWP。
BWP的选择或BWP的切换可以通过以下几种方式实现:
(1)通过专用的RRC信令配置:由于RRC消息的处理需要额外的时间,延迟可达10msec,更适合于半静态情况。由于更长的切换延迟和信令开销,基于RRC的配置方式可用于在呼叫的任何阶段配置BWP集,或用于在同一数据会话中资源分配不会快速变化的慢适应类型服务,例如语音服务。
(2)通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)的下行控制信息(Downlink Control Information,DCI)下发:基于PDCCH通道,可以通过下行控制信息格式DCI 0_1(即上行授权(UL Grant))和下行控制信息格式DCI 1_1(下行调度(DL Scheduling))的BWP指示(indicator)激活特定的BWP。这种方式更适合动态BWP切换,因为使用这种方式延迟低至2毫秒。然而,这种方式需要额外考虑错误处理,因为终端设备可能无法解码包含BWP激活/去激活命令的DCI。
(3)通过BWP非激活定时器(BWP-inactivityTimer)切换:如果在定时器超时前,没有显式地为终端调度BWP,则会自动切换到默认的BWP;其中,BWP非激活定时器是位于ServingCellConfig.bwp(服务小区配置.部分载波带宽)中的非激活定时器(InactivityTimer):
(4)在随机接入(Random Access,RA)过程中通过媒体接入控制(Media Access Control,MAC)层信令来进行BWP切换,如果在PRACH时机上没有配置激活的上行BWP(UL BWP),则根据高层参数initialUplinkBWP(初始上行BWP)指示的BWP转换到激活的UL BWP。如果当前是SpCell(特殊小区),则根据initialDownlinkBWP(初始下行BWP)指示的BWP转换到激活的下行BWP(DL BWP);如果在PRACH时机上配置激活了的UL BWP且小区是SpCell,且激活的DL BWP与激活的UL BWP不一致,则需要转换激活的DL BWP,保证激活的DL BWP和UL BWP一致,这样设计的目的是为了保证终端设备在发送完PRACH后可以监听PDCCH。
2、时隙内跳频和时隙间跳频
物理上行共享信道(Physical Uplink Shared Channel,PUSCH)跳频是指终端设备发送PUSCH在某一时刻占用一段连续的频段,在下一时刻跳转到另一个频段,通过PUSCH跳频可以实现足够的频率选择性增益和干扰随机化效果。NR中支持两种跳频模式,可通过高层信令PUSCH-config(PUSCH配置)的frequencyHopping(频率跳频)参数来配置,分为时隙内跳频和时隙间跳频。
时隙内跳频是指PUSCH在同一个时隙内的两个Hop(跳)上传输,这两个Hop分别为第一Hop(跳)和第二Hop(跳)。两个Hop在频率上具有一定的间隔,称为频率偏移(Frequency Offset),其值可用RBoffset表示。两个Hop各自包含时隙内不同的连续个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。时隙内跳频可以改善一次PUSCH传输的频率分集和干扰抑制。
时隙间跳频是指时域上一个时隙可以看作一个Hop,不同Hop上传输的PUSCH有频率偏移。时隙间跳频应用于多时隙的PUSCH传输,从而改善两次PUSCH传输之间的频率分集和干扰抑制。
对于动态调度PUSCH(DG-PUSCH)的频域资源分配类型1(Type 1),如果配置了PUSCH跳频,调度PUSCH的DCI的FDRA域或字段中有NUL_hop个比特用于指示频率偏移值,可以将NUL_hop个比特称为上行跳频比特。网络设备通过控制频率偏移值来控制PUSCH的跳频范围,频率偏移值大小可由高层信令PUSCH-config(PUSCH配置)中的frequencyHoppingOffsetLists(频率跳频偏移列表)参数配置,可选地,可以配置2个或者4个频率偏移值。例如,当BWP中的PRB个数小于50时,NUL_hop为1比特,且frequencyHoppingOffsetLists包含两个频率偏移值;当BWP中的PRB个数大于或等于50时,NUL_hop为2比特,且frequencyHoppingOffsetLists包含四个频率偏移值;其中,NUL_hop不同的比特取值对应不同的频率偏移值。
对于配置授权PUSCH(CG-PUSCH),频率偏移值大小可由高层信令ConfiguredGrantConfig(配置授权配置)中的frequencyHoppingOffset(频率跳频偏移)参数配置若干频率偏移值,并由DCI从若干频率偏移值中激活当前用于上行跳频的频率偏移值。
3、随机接入(Random Access,RA)过程
RA过程是指从终端设备发送RA前导码(preamble)开始尝试接入网络到与网络间建立起基本的信令连接之前的过程。RA过程支持2种类型:4步(4-step)RA类型和2步(2-step)RA类型。这两种类型都支持基于竞争的随机接入(contention-based random access,CBRA)。其中,4步RA的CBRA过程包括4个步骤:步骤1、终端设备发送PRACH承载RA preamble,即消息1(Msg1)传输;步骤2、网络设备发送物理下行共享信道(Physical downlink Shared Channel,PDSCH)承载的随机接入响应(Random Access Response,RAR)消息,即消息2(Msg2)传输;步骤3、终端设备发送PUSCH承载的消息3(Msg3),即Msg3传输;步骤4、网络设备发送PDSCH承载的竞争解决(contention resolution)消息,即消息4(Msg4)传输。
2步RA的CBRA过程包括2个步骤:步骤1、终端设备发送PRACH承载的RA preamble和PUSCH,即消息(MsgA)传输;步骤2、网络设备发送PDSCH承载的竞争解决消息,即消息B(MsgB)传输。然而,如果网络设备仅接收到MsgA中的preamble,但是并未收到MsgA中的PUSCH,网络设备会发起回退过程。2步RA的CBRA回退(fallback)过程包括4个步骤:步骤1、终端设备发送PRACH承载的RA preamble和PUSCH,即MsgA传输;步骤2、网络设备发送PDSCH承载的回退RAR消息,即MsgB传输;步骤3、终端设备发送PUSCH承载的Msg3,即Msg3传输;步骤4、网络设备发送PDSCH承载的竞争解决消息,即Msg4传输。
RAR消息中包含上行授权(UL Grant)信息,可以称为RAR UL Grant,也可以简称为RAR Grant。回退RAR也可成为回退指示(fallback indication)消息,该回退指示中包含UL Grant,可称为fallback RAR UL Grant,也可以简称为fallback RAR Grant。该RAR UL Grant和fallback RAR UL Grant都可用于调度承载Msg3的PUSCH,该Msg3携带终端设备的标识信息。为描述方便,RAR可以是4步RA过程中的RAR,或者,2步RA过程中的回退RAR。同理,RAR UL Grant,可以是4步RA过程中的RAR UL Grant,或者,2步RA过程中的回退RAR UL Grant。
4、资源指示值(Resource Indication Value,RIV)
RIV用于表示资源分配,通过RIV可以推导出分配给终端设备的用于进行传输(例如用于传输Msg3)的起始资源块(Resource Block,RB)及连续分配的RB的长度。其中,RB的长度可以为RB的数量。例如,RA场景中,Msg3通过PUSCH进行传输,其初传调度信息通过Msg2中携带的RAR Grant指示,RAR Grant中包括PUSCH频域资源指示(PUSCH frequency resource allocation)域,PUSCH frequency resource allocation可以指示Msg3的频域资源分配,即PUSCH frequency resource allocation可以包括一个与用于传输上行信息的起始RB和连续分配的RB的长度对应的RIV。又如,在采用连续PRB资源分配的type1(类型1)的下行频域资源分配方式的情况下,type1资源分配字段包含一个RIV,该RIV对应用于传输下行信息的起始RB和连续分配的RB的长度。
5、子带全双工(Subband Full Duplex,SBFD)和非子带全双工(non-Subband Full Duplex,非SBFD)
由于时分双工(Time domain duplex,TDD)系统上下行时隙配比的限制,导致时分双工系统的传输时延较大。为了降低基站的实现复杂度,一个时分双工载波的所有频域资源在同一时刻的传输方向需相同,同为上行或下行,即一个时分双工载波不同频域资源的上、下行时隙配比不能灵活配置。随着业务的多元化,尤其是考虑垂直行业的业务需求,不同业务对上、下行的传输需求不同,单一的上、下行时隙配比不能满足不同业务的需求。基于以上两点,同时考虑基站实现复杂度,有人提出了子带全双工的解决方案,即同一载波的不同子带(Subband)采用不同的上、下行时隙配比。
一个载波分量在下行符号或者灵活符号上,频域范围内划分为多个子带,多个子带包括上行子带(UL Subband)和下行子带(DL Subband),网络设备可以在下行子带发送下行信号且同时在上行子带接收上行信号,即一个符号在频域上同时包含下行子带和上行子带,可称为SBFD符号;为了在后续便于描述,SBFD符号对应的时频资源可称为SBFD资源;其中,SBFD资源包括SBFD的上行资源和SBFD的下行资源,SBFD的上行资源是指SBFD符号内的上行子带部分,SBFD的下行资源是指SBFD符号内的下行子带部分。相应地,在一个符号在频域上同时只包含下行资源或上行资源,可称为非SBFD符号;为了在后续便于描述,非SBFD对应的时频资源可称为非SBFD资源。
示例性地,请参阅图2,图2是本申请实施例提供的一种时频资源的上、下行TDD配置示意图。图2中的D表示传输下行信号的时频资源,U表示传输上行信号的时频资源。其中,时隙(slot)n、时隙n+1、时隙n+2、时隙n+3为下行符号,时隙n+4为上行符号。在时隙n+1、时隙n+2、时隙n+3对应的频域位置中,不同子带可以分别传输下行信号和上行信号,将时隙n+1、时隙n+2、时隙n+3对应的时频资源称为SBFD资源,图2中示出了上行子带;时隙n对应的频域资源用于传输下行信号,时隙n+4对应的频域资源用于传输上行信号,将时隙n和时隙n+4对应的时频资源称为非SBFD资源。需说明的是,图2仅是对SBFD资源和非SBFD资源的上、下行TDD配置进行举例,并不限定两种资源用于传输上行信号和下行信号的资源配比。可选地,时隙n+1、时隙n+2、时隙n+3还可以为灵活符号。
可选地,终端设备可以根据网络设备发送的公共上下行配置信息获取TDD上、下行配置,或者,终端设备可以根据网络设备发送的公共上下行配置信息和专用上下行配置信息获取TDD上、下行配置,根据TDD上、下行配置确定载波中的SBFD资源和非SBFD资源。或者说,系统提供多种时隙格式(slot format)的配置方式,其中,时隙格式包括下行符号,上行符号和灵活符号的时隙格式。终端设备可以根据网络设备发送的公共上下行配置信息获取时隙格式,或者,终端设备可以根据网络设备发送的公共上下行配置信息和专用上下行配置信息获取时隙格式,根据时隙格式确定载波中的SBFD资源和非SBFD资源。
针对上述提出的SBFD的解决方案,如何确定SBFD资源内用于进行传输的频域资源,还需进一步研究。
鉴于此,本申请实施例提供一种资源确定方法及通信装置,能够有效确定SBFD资源内用于进行传输的频域资源,有助于终端设备利用SBFD资源与网络设备进行通信。
下面基于图1所示的系统架构,对本申请实施例提供的资源确定方法进行详细介绍。本申请实施例中的执行主体可以为终端设备和网络设备。或者本申请实施例中的执行主体可以为与终端设备匹配的装置,例如,处理器、芯片或芯片模组,以及与网络设备匹配的装置,例如,处理器、芯片或芯片模组。下面以终端设备和网络设备为例进行说明。
请参见图3,图3是本申请实施例提供的一种资源确定方法的流程示意图,该方法可以包括但不限于如下步骤:
301,终端设备接收来自网络设备的FDRA字段,FDRA字段用于确定资源指示信息,资源指示信息用于从第一频域资源中确定第一传输频域资源,第一频域资源基于第一重叠资源确定,第一重叠资源为第二频域资源与SBFD资源内的子带重叠的频域资源。相应地,网络设备向终端设备发送FDRA字段。
其中,第二频域资源为上行频域资源或下行频域资源。上行频域资源是网络设备配置或指示给终端设备的可以用于进行上行传输的频域资源,例如,初始上行BWP或当前的激活上行BWP等,其中,当前的激活上行BWP是终端设备当前被激活的专用BWP。下行频域资源是网络设备配置或指示给终端设备的可以用于进行下行传输的频域资源,例如,承载DCI的PDCCH的CORESET。
可选地,第二频域资源为上行频域资源,第一重叠资源为第二频域资源与SBFD资源内的上行子带重叠的频域资源;或者,第二频域资源为下行频域资源,第一重叠资源为第二频域资源与SBFD资源内的下行子带重叠的频域资源。
终端设备在执行步骤301之前,可以基于第一重叠资源,确定第一频域资源。终端设备在执行步骤301之后,可以根据资源指示信息,从第一频域资源中确定第一传输频域资源。
可选地,终端设备基于第一重叠资源,确定第一频域资源可以包括:终端设备基于第一重叠资源,确定第一频域资源的起始资源以及第一频域资源的资源数量。其中,第一频域资源的资源数量可以看作是第一频域资源的资源长度。
基于第一重叠资源,确定的第一频域资源可以有以下三种情况中的至少一种:
情况1,激活上行BWP包含初始上行BWP,第一频域资源的起始资源为第一重叠资源内的第一个资源块,且第一频域资源的资源数量为第一重叠资源内的资源块数量;其中,第二频域资源为初始上行BWP,第一重叠资源为初始上行BWP与SBFD资源内的上行子带重叠的频域资源。
情况1中,在激活上行BWP包含初始上行BWP的情况下,第二频域资源为初始上行BWP,第一重叠资源为初始上行BWP与SBFD资源内的上行子带重叠的频域资源,从而终端设备基于第一重叠资源,确定第一频域资源的起始资源为第一重叠资源内的第一个资源块,且第一频域资源的资源数量为第一重叠资源内的资源块数量。
其中,这里的激活上行BWP可以看作是终端设备的当前激活上行BWP。激活上行BWP包含初始上行BWP是指激活上行BWP完全包含初始上行BWP,即初始上行BWP中的每个资源块均包含在激活上行BWP中,又即初始上行BWP的资源区域完全包含在激活上行BWP的资源区域中。可选地,在激活上行BWP包含初始上行BWP的同时,激活上行BWP的循环前缀(Cyclic Prefix,CP)与初始上行BWP的CP相同,激活上行BWP的子载波间隔(Subcarrier Spacing,SCS)与初始上行BWP的SCS相同。
可选地,第一重叠资源内的第一个资源块可以是指第一重叠资源内的第一个完整资源块;第一重叠资源内的资源块数量可以是指第一重叠资源内的完整资源块数量。资源块完全包含于第一重叠资源中,即资源块的资源区域完全位于第一重叠资源的资源区域中,则该资源块可称为第一重叠资源内的完整资源块;例如,第一重叠资源包含资源块0至资源块10等11个资源块,资源块3完全包含于第一重叠资源中,即资源块3的资源区域完全包含于第一重叠资源的资源区域中,则资源块3可称为第一重叠资源内的完整资源块;又如,资源块A的一半资源区域位于第一重叠资源中,资源块11的另一半资源区域位于第一重叠资源之外,则资源块11不是第一重叠资源内的完整资源块。第一频域资源的起始资源为第一重叠资源内的第一个资源块是指第一频域资源的资源块计数开始于第一重叠资源内的第一个完整资源块,可以将第一频域资源的起始资源标记为RB0或PRB(Physical Resource Block,物理资源块)0。
示例性地,请参阅图4,图4是本申请实施例提供的一种SBFD资源、激活上行BWP和初始上行BWP之间的位置关系示意图。图4中,激活上行BWP包含初始上行BWP,激活上行BWP的CP与初始上行BWP的CP相同,且激活上行BWP的SCS与初始上行BWP的SCS相同;载波或小区内SBFD资源的上行子带的频域资源位于CRB10-CRB40,在SBFD资源中标记为灰色资源块;第一重叠资源为初始上行BWP与SBFD资源内的上行子带重叠的频域资源,即CRB39和CRB40共2个CRB,在初始上行BWP标记为灰色资源块;第一重叠资源内第一个完整资源块为CRB39,从CRB39开始计数,将CRB39作为第一频域资源的起始资源,即第一频域资源的PRB0;第一重叠资源的完整资源块包括CRB39和CRB40共2个CRB,则第一频域资源的资源数量为2个。其中,激活上行BWP中与SBFD资源内的上行子带重叠的资源块标记为灰色资源块。
示例性地,请参阅图5,图5是本申请实施例提供的另一种SBFD资源、激活上行BWP和初始上行BWP之间的位置关系示意图。图5中,激活上行BWP包含初始上行BWP,激活上行BWP的CP与初始上行BWP的CP相同,且激活上行BWP的SCS与初始上行BWP的SCS相同;载波或小区内SBFD资源的上行子带的频域资源位于CRB10-CRB40,在SBFD资源中标记为灰色资源块;第一重叠资源为初始上行BWP与SBFD资源内的上行子带重叠的频域资源,即CRB11-CRB39共19个CRB,在初始上行BWP标记为灰色资源块;第一重叠资源内第一个完整资源块为CRB11,从CRB11开始计数,将CRB11作为第一频域资源的起始资源,即第一频域资源的PRB0;第一重叠资源的完整资源块包括CRB11-CRB39共19个CRB,则第一频域资源的资源数量为19个。其中,激活上行BWP中与SBFD资源内的上行子带重叠的资源块标记为灰色资源块。
情况2,初始上行BWP有频域资源位于激活上行BWP的频域资源区域之外,第一频域资源的起始资源为第一重叠资源内的第一个资源块,且第一频域资源的资源数量为第一重叠资源内的资源块数量或者初始上行BWP的资源块数量;其中,第二频域资源为激活上行BWP,第一重叠资源为激活上行BWP与SBFD资源内的上行子带重叠的频域资源。
方式2中,在初始上行BWP有频域资源位于激活上行BWP的频域资源区域之外的情况下,第二频域资源为激活上行BWP,第一重叠资源为激活上行BWP与SBFD资源内的上行子带重叠的频域资源,从而终端设备基于第一重叠资源,确定第一频域资源的起始资源为第一重叠资源内的第一个资源块,且第一频域资源的资源数量为第一重叠资源内的资源块数量或者初始上行BWP的资源块数量。
其中,这里的激活上行BWP可以看作是终端设备的当前激活上行BWP。初始上行BWP有频域资源位于激活上行BWP的频域资源区域之外,包括两种情形:情形1,激活上行BWP与初始上行BWP不重叠;情形2,激活上行BWP包含初始上行BWP的部分频域资源。其中,激活上行BWP与初始上行BWP不重叠,是指初始上行BWP中的资源块均不在激活上行BWP的资源区域中,又即初始上行BWP的频域资源区域与激活上行BWP的频域资源区域完全不重叠。激活上行BWP包含初始上行BWP的部分频域资源是指初始上行BWP中的部分频域资源位于激活上行BWP的资源区域中,初始上行BWP中的其余部分频域资源位于激活上行BWP的资源区域之外。
关于第一重叠资源内的第一个资源块和第一重叠资源内的资源块数量的含义可参见前述情况1中的描述,在此不作赘述。
示例性地,请参阅图6,图6是本申请实施例提供的再一种SBFD资源、激活上行BWP和初始上行BWP之间的位置关系示意图。图6中,激活上行BWP包含初始上行BWP的部分频域资源;载波或小区内SBFD资源的上行子带的频域资源位于CRB10-CRB40,在SBFD资源中标记为灰色资源块,激活上行BWP的第一个资源块为CRB8;第一重叠资源为激活上行BWP与SBFD资源内的上行子带重叠的频域资源,即CRB10-CRB15共6个CRB,在激活上行BWP中标记为灰色资源块;第一重叠资源内的第一个完整资源块为CRB10,从CRB10开始计数,将CRB10作为第一频域资源的起始资源,即第一频域资源的PRB0;第一重叠资源的完整资源块包括CRB10-CRB15共6个CRB,初始上行BWP包括7个CRB,则第一频域资源的资源数量为6个或7个。需说明的是,图6中省略了SBFD资源内的上行子带的部分资源块,故激活上行BWP和初始上行BWP与SBFD资源的省略资源块并没有对齐。其中,初始上行BWP中与SBFD资源内的上行子带重叠的资源块标记为灰色资源块。
需说明的是,激活上行BWP、初始上行BWP与SBFD资源的上行子带相互之间可以部分重叠、不重叠和完全重叠。示例性地,请参阅图7,图7是本申请实施例提供的一种激活上行BWP、初始上行BWP与SBFD资源的上行子带之间的位置关系示意图。图7中,D表示SBFD资源的下行子带,U表示SBFD资源的上行子带,图7示出了激活上行BWP完全包含初始上行BWP,激活上行BWP包含初始上行BWP的部分频域资源,激活上行BWP完全包含SBFD资源的上行子带,初始上行BWP完全包含SBFD资源的上行子带,初始上行BWP与SBFD资源完全不重叠,SBFD资源的上行子带包含初始上行BWP的部分频域资源等情况。
情况3,第一频域资源的起始资源为第一重叠资源内的第一个资源块,第一频域资源的资源数量为第一重叠资源内的资源块数量;其中,第二频域资源为承载DCI的PDCCH所处的CORESET,第一重叠资源为承载DCI的PDCCH所处的CORESET与SBFD资源内的下行子带重叠的频域资源。
可选地,关于第一重叠资源内的第一个资源块和第一重叠资源内的资源块数量的含义可参见前述情况1中的描述,在此不作赘述。
从第一频域资源中确定出的第一传输频域资源可以为以下两种频域资源中的至少一种:
频域资源1:SBFD资源的上行子带内用于传输Msg3的频域资源;其中,SBFD资源位于下行符号和/或灵活符号内;
频域资源2:公共搜索空间(Common Search Space,CSS)内以第一DCI格式调度的PDSCH的频域资源;可选地,第一DCI格式可以是DCI1_0。
关于Msg3的描述可以参见前述相关概念中RA过程的阐述,在此不作赘述。
可选地,从情况1和/或情况2的第一频域资源中确定的第一传输频域资源可以是上述频域资源1;从情况3的第一频域资源中确定的第一传输频域资源可以是上述频域资源2。
可选地,对于情况1和/或情况2的场景,FDRA字段可以携带于RAR Grant、DCI或高层信令中。对于由情况3的场景,FDRA字段可以携带于DCI或高层信令中。可选地,高层信令可以为RRC信令。
在一种实现方式中,对于情况1和/或情况2的场景,终端设备还根据第一频域资源的资源数量,对FDRA字段进行截断或扩展处理;根据截断或扩展处理后的FDRA字段,确定资源指示信息。
其中,终端设备通过对接收到的FDRA字段进行截断或扩展处理,确定用于确定资源指示信息的有效位。
可选地,终端设备根据第一频域资源的资源数量,对FDRA字段进行截断或扩展处理,包括:终端设备响应于第一频域资源的资源数量小于或等于资源数量阈值,将FDRA字段截断到第一数量的最低有效位;或者,终端设备响应于第一频域资源的资源数量大于资源数量阈值,在FDRA字段中的上行跳频比特之后插入第二数量的零比特(bit)。
将FDRA字段截断到第一数量的最低有效位是指从FDRA字段的最低位开始连续取FDRA字段中第一数量的低位比特,例如,FDRA字段为14比特,第一数量为12,则从FDRA字段的最低位比特开始确定连续的12比特为用于确定资源指示信息的有效位,即这12比特形成新的可用于确定资源指示信息的FDRA字段。在FDRA字段中的上行跳频比特之后插入第二数量的零比特,表示在FDRA字段中的上行跳频比特之后插入第二数量的取值为0的比特,扩展形成新的FDRA字段,新的FDRA字段可以用于确定资源指示信息。
其中,第一数量根据所述第一频域资源的资源数量确定,第二数量根据所述第一频域资源的资源数量确定。例如,第一数量可以为log2[N1·(N1+1)/2],N1为第一频域资源的资源数量,N1为大于或等于1的整数。又如,第二数量可以为log2[N1·(N1+1)/2]-14,N1为第一频域资源的资源数量,N1为大于或等于1的整数。资源数量阈值可以由高层信令配置,也可以由系统设置,在此不对资源数量阈值的确定方式进行限定。上行跳频比特用于指示上行跳频的频率偏移值,上行跳频的频率偏移值用于确定上行跳频的频域资源,例如,上行跳频比特可以用于指示:用于重复传输PUSCH的上行跳频的频域资源。
在另一种实现方式中,对于情况3的场景,终端设备接收到来自网络设备的FDRA字段,对FDRA字段并不作前述截断或扩展处理,从FDRA字段中获取资源指示信息。
可选地,资源指示信息可以是RIV。可选地,RIV的确定方式可以如下:
如果则RIV=N1(LRBs-1)+RBstart,如果则RIV=N1(N1-LRBs+1)+(N1-1-RBstart)。
其中,网络设备根据上述RIV的确定方法确定终端设备的RIV时,RBstart为第一传输频域资源在第一频域资源内的起始位置,LRBs为第一传输频域资源的长度,N1为第一频域资源的大小即资源块数量。其中,LRBs≥1,并且不能超过N1-RBstart是向下取整运算。
可选地,终端设备对RIV进行上述RIV的确定方法的逆运算,确定第一传输频域资源,即确定第一传输频域资源在第一频域资源内的起始位置和长度。
在图3所示的实施例中,第一频域资源基于第一重叠资源确定,由于第一重叠资源为第二频域资源与SBFD资源的子带重叠的频域资源,第一频域资源与SBFD资源对应;终端设备还接收来自网络设备的FDRA字段,FDRA字段用于确定资源指示信息,能够根据资源指示信息从第一频域资源中确定第一传输频域资源,由于第一频域资源与SBFD资源对应,实现了从第一频域资源中有效确定SBFD资源内用于进行传输的频域资源,有助于终端设备利用SBFD资源与网络设备进行通信。
请参见图8,图8是本申请实施例提供的另一种资源确定方法的流程示意图,该方法可以包括但不限于如下步骤:
801,终端设备接收来自网络设备的FDRA字段,FDRA字段用于确定资源指示信息,资源指示信息用于从第一频域资源中确定第一传输频域资源,第一频域资源基于第一重叠资源确定,第一重叠资源为第二频域资源与SBFD资源内的子带重叠的频域资源。相应地,网络设备向终端设备发送FDRA字段。
其中,第二频域资源为上行频域资源或下行频域资源。
802,终端设备根据第一传输频域资源和频率偏移值,确定第二传输频域资源。
其中,第一传输频域资源和第二传输频域资源是SBFD资源的上行子带内用于上行跳频的频域资源,SBFD资源位于下行符号和/或灵活符号内。步骤802中的频率偏移值可以看作是SBFD资源对应的频率偏移值,即用于在SBFD资源内确定跳频频域资源的频率偏移值。
例如,第一传输频域资源和第二传输频域资源可以是用于传输处于重复传输模式下的PUSCH的跳频频域资源。又如,第一传输频域资源和第二传输频域资源可以是用于传输处于重复传输模式下的物理上行控制信道(Physical Uplink Control Channel,PUCCH)的跳频频域资源。
需说明的是,第一传输频域资源可以是从图3所示方法实施例中的情况1和/或情况2的第一频域资源中确定,从而步骤801可以参见图3所示方法实施例中步骤301的描述,在此不作赘述。第二传输频域资源根据所述第一传输频域资源和频率偏移值确定。
在一种实现方式中,第一传输频域资源和第二传输频域资源用于传输Msg3。频率偏移值由FDRA字段中的上行跳频比特指示。上行跳频比特指示的频率偏移值和上行跳频比特指示的频移偏移值的数量根据第二重叠资源的资源数量确定,第二重叠资源为初始上行BWP和SBFD资源的上行子带重叠的频域资源。关于Msg3的描述可以参见前述相关概念中RA过程的阐述,在此不作赘述。
可选地,第二重叠资源的资源数量可以是第二重叠资源内的完整资源块数量。其中,资源块完全包含于第二重叠资源中,即资源块的资源区域完全位于第二重叠资源的资源区域中,则该资源块可称为第二重叠资源内的完整资源块。
可选地,FDRA字段中NUL_hop个比特用于指示频率偏移值,可以将NUL_hop个比特称为上行跳频比特,即可以通过上行跳频比特配置多个频率偏移值。例如,可以通过高层信令配置频率跳频偏移列表,该列表中配置了多个频率偏移值,可以参见下表1。
表1
表1中,响应于N2小于资源块数量阈值,上行跳频比特为1比特,上行跳频比特取值为0表示频率偏移值为上行跳频比特取值为1表示频率偏移值为响应于N2大于或等于资源块数量阈值,上行跳频比特为2比特,上行跳频比特取值为00表示频率偏移值为上行跳频比特取值为01表示频率偏移值为上行跳频比特取值为10表示频率偏移值为上行跳频比特取值为11表示保留,其中,资源块数量阈值可以根据高层信令配置,N2表示第二重叠资源的资源数量。
在另一种实现方式中,第一传输频域资源和第二传输频域资源可以是SBFD资源的上行子带内用于第一上行跳频和/或第二上行跳频的频域资源。其中,第一上行跳频为用于传输PUSCH的上行跳频,第二上行跳频为用于传输PDCCH的上行跳频。
终端设备根据第一传输频域资源和频率偏移值,确定第二传输频域资源,包括:终端设备根据频率偏移值对第一传输频域资源的索引进行偏移处理;终端设备将偏移处理后的第一传输频域资源的索引与第三重叠资源的资源数量进行取模处理,得到第二传输频域资源的索引。
其中,第三重叠资源为激活上行BWP与SBFD资源的上行子带重叠的频域资源。第三重叠资源的资源数量可以是指第三重叠资源中的完整资源块数量。资源块完全包含于第三重叠资源中,即资源块的资源区域完全位于第三重叠资源的资源区域中,则该资源块可称为第三重叠资源内的完整资源块。
例如,终端设备根据频率偏移值对第一传输频域资源内的起始资源的索引进行偏移处理,将偏移处理后的起始资源的索引与第三重叠资源的资源数量进行取模处理,得到第二传输频域资源的起始资源的索引,根据由RIV确定的第一传输频域资源的资源长度确定第二传输频域资源的资源长度,即第二传输频域资源的资源长度与第一传输频域资源的资源长度相同。其中,第一传输频域资源的起始资源的索引可以表示为RBstart,第二传输频域资源的起始资源的索引可以表示为(RBstart+RBoffset)modN3,RBoffset表示频率偏移值,N3表示第三重叠资源的资源数量。
又如,终端设备根据频率偏移值对第一传输频域资源内的所有资源的索引进行偏移处理,将偏移处理后的第一传输频域资源内的所有资源的资源索引与第三重叠资源的资源数量进行取模处理,得到第二传输频域资源的所有资源的索引。
进行上述取模处理是为了避免进行偏移处理后的资源索引所标记的资源位于SBFD资源的上行子带之外,从而确保了终端设备能够通过第二传输频域资源进行上行跳频的传输。
示例性地,请参阅图9,图9是本申请实施例提供的一种第一传输频域资源与第二传输频域资源之间的位置关系示意图。图9中,D表示SBFD资源内的下行子带,U表示SBFD资源内的上行子带,根据频率偏移值对第一传输频域资源的索引进行偏移处理,得到的偏移处理后的第一传输频域资源的索引所标识的频域资源可能位于SBFD资源的下行子带中,进一步将偏移处理后的第一传输频域资源的索引与第三重叠资源的资源数量进行取模处理,得到第二传输频域资源的索引,使得第二传输频域资源位于SBFD资源的上行子带中而能够用于进行上行传输。
可选地,频率偏移值承载于DCI或高层信令中。例如,对于DG-PUSCH的频域资源分配Type 1,DCI的FDRA字段中的上行跳频比特指示频率偏移值。又如,由步骤802接收到的FDRA字段中的上行跳频比特指示频率偏移值。再如,对于CG-PUSCH,频域偏移值可由高层信令配置,可选地,还可通过DCI激活由高层信令配置的频率偏移值。
可选地,频率偏移值可以根据第三重叠资源的资源数量确定。其中,频率偏移值可以小于或等于第三重叠资源的资源数量-1。
可选地,终端设备还可以根据来自网络设备的FDRA字段,确定用于指示非SBFD资源内的用于上行跳频的第三传输频域资源,并根据非SBFD资源对应的频率偏移值和第三频域资源确定第四频域资源。其中,非SBFD资源对应的频率偏移值也可以承载于DCI或高层信令中,与前述SBFD资源对应的频率偏移值的承载方式类似,在此不作赘述。可选地,非SBFD资源对应的频率偏移值与前述SBFD资源对应的频率偏移值可以相同或不同。

在另一种实现方式中,对于情况二,上行跳频为PUCCH的第二上行跳频,上述偶时隙的索引为SBFD资源内的偶时隙索引,上述奇时隙的索引为SBFD资源内的奇时隙索引。其中,可以将上述偶时隙的索引和上述奇时隙的索引看作是SBFD资源内的相对时隙索引。例如,将SBFD资源内PUCCH重复传输的第一个时隙标记为SBFD资源的时隙0,SBFD资源的时隙0为该时隙的索引,从SBFD资源的时隙0开始对SBFD资源内后续的时隙依次进行计数标记,得到SBFD资源内的相对时隙索引。
可选地,还可以将非SBFD资源内的PUCCH重复传输的第一个时隙标记为非SBFD资源的时隙0,非SBFD资源的时隙0为该时隙的索引,从非SBFD资源的时隙0开始对非SBFD资源内后续的时隙依次进行计数标记,得到非SBFD资源内的相对时隙索引。
示例性地,请参阅图12,图12是本申请实施例提供的一种时隙间跳频模式下第二上行跳频的跳频频域资源的示意图。图12中,非SBFD资源时隙0、非SBFD资源时隙1、非SBFD资源时隙2是非SBFD资源内的相对时隙索引,即上行BWP内的相对时隙索引,SBFD资源时隙0、SBFD资源时隙1是SBFD资源内的相对时隙索引;非SBFD资源时隙0、非SBFD资源时隙2对应的频域资源中灰色标记的资源块为第三传输频域资源,RB1为第三传输频域资源的起始资源,非SBFD资源时隙1对应的频域资源中灰色标记的资源块为第四传输频域资源,RB1’为第四传输频域资源的起始资源;SBFD资源时隙0对应的频域资源中灰色标记的资源块为第一传输频域资源,RB2为第一传输频域资源的起始资源,SBFD资源时隙1对应的频域资源灰色标记的资源块为第二传输频域资源,RB2’为第二传输频域资源的起始资源。

可选地,一个时隙间隔内可能存在SBFD资源和非SBFD资源。时隙间隔内的非BFD资源也可以用于PUSCH的上行跳频。
示例性地,请参阅图13,图13是本申请实施例提供的一种上行跳频的跳频频域资源的示意图。可选地,图13可以表示情况三中第一上行跳频的跳频频域资源,其中,各时隙间隔索引均是系统无线帧中的绝对时隙间隔索引,并且各时隙间隔索引所标记的时隙间隔内均存在SBFD资源和非SBFD资源(上行BWP);时隙间隔0、时隙间隔2的SBFD资源中灰色标记的资源块为第一传输资源,RBstart为第一传输资源的起始资源,时隙间隔1的SBFD资源中灰色标记的资源块为第二传输资源;时隙间隔0、时隙间隔2的非SBFD资源中灰色标记的资源块为第三传输资源,时隙间隔1的非SBFD资源中灰色标记的资源块为第四传输资源。
在另一种实现方式中,对于情况三,上行跳频为PUCCH的第二上行跳频,偶时隙间隔的索引为SBFD资源内的偶时隙间隔索引,奇时隙间隔的索引为SBFD资源内的奇时隙间隔索引。其中,可以将上述偶时隙间隔索引和上述奇时隙间隔索引看作是SBFD资源内的相对时隙间隔索引。例如,将SBFD资源内PUCCH重复传输的第一个时隙间隔标记为SBFD资源的时隙间隔0,SBFD资源的时隙间隔0为该时隙间隔的索引,从SBFD资源的时隙间隔0开始对SBFD资源内后续的时隙间隔依次进行计数标记,得到SBFD资源内的相对时隙间隔索引。
可选地,还可以将非SBFD资源内的PUCCH重复传输的第一个时隙间隔标记为非SBFD资源的时隙间隔0,非SBFD资源的时隙间隔0为该时隙间隔的索引,从非SBFD资源的时隙间隔0开始对非SBFD资源内后续的时隙间隔依次进行计数标记,得到非SBFD资源内的相对时隙间隔索引。
由于一个时隙间隔内可能存在SBFD资源和非SBFD资源,SBFD资源的相对时隙间隔索引和非SBFD资源的相对时隙间隔索引可能编号相同或不同。例如,图13可以表示情况三中第二上行跳频的跳频频域资源,时隙间隔0、时隙间隔1、时隙间隔2可以表示SBFD资源的相对时隙间隔,也可以表示非BFD资源的相对时隙间隔,其他表示方式与前述图13表示情况三中第一上行跳频的跳频频域资源的表示方式相同,在此不作赘述。
在图8所示的实施例中,第一频域资源基于第一重叠资源确定,由于第一重叠资源为第二频域资源与SBFD资源的子带重叠的频域资源,第一频域资源与SBFD资源对应,终端设备接收来自网络设备的FDRA字段,FDRA字段用于确定资源指示信息,能够根据资源指示信息从第一频域资源中确定第一传输频域资源,由于第一频域资源与SBFD资源对应,实现了从第一频域资源中有效确定SBFD资源内用于进行传输的频域资源;并且还根据用于上行跳频的第一传输频域资源和频率偏移值,确定用于上行跳频的第二传输频域资源,从而有效确定了SBFD资源内用于上行跳频的频域资源,有助于终端设备利用SBFD资源与网络设备进行通信。
