本公开涉及通信技术领域,尤其涉及一种信息处理方法、装置及可读存储介质。
为了解决时分双工(Time domain duplex,TDD)模式下上行传输的覆盖、时延和容量问题,将研究非重叠子带全双工(non-overlapping sub-band full duplex)这一技术,即将频域资源划分为多个子带,且互相不重叠,上行和下行频域资源分别位于不同子带,下文简称为全双工。
当网络从静态/动态TDD模式切换到全双工模式后,会导致切换之前配置给终端的用于重复传输的资源不可用,或者,当网络从静态/动态TDD模式切换到全双工模式后,会有更丰富的上行/下行传输资源。相关技术中,终端的重复传输的时频域传输资源是通过下行控制信息(Downlink Control Information,DCI)一次性配置的,从而可能会导致重复传输中断,或者,无法利用丰富的上行/下行传输资源。

本公开实施例提供了一种信息处理方法及装置,用以节约资源。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
参见图1,图1是本公开实施例提供的信息处理方法的流程图,如图1所示,包括以下步骤:
步骤101、网络设备向终端发送第一DCI,用于调度目标TB的重复传输。
其中,所述目标TB可以是任意的TB。在实际应用中,网络通过第一DCI调度目标TB的新传或者HARQ重传,且可通过第一DCI或者无线资源控制(Radio Resource Control,RRC)信令配置所述目标TB的重复次数。因此,第一DCI可为首次调度目标TB的新传或者HARQ重传的DCI,可以采用现有的任意的DCI格式实现。
步骤102、所述网络设备向所述终端发送第二DCI。
其中,所述第二DCI为对所述目标TB所在的HARQ process进行调度的DCI,所述第二DCI中的指示信息或者所述第二DCI的格式用于指示所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
在本公开实施例中,剩余重复传输为根据配置的所述目标TB的重复传输次数,在第二DCI的生效起始时间时,所述终端未执行的重复传输。也即,剩余重复传输为剩余重复传输次数对应的重复传输,剩余重复传输次数为在该第二DCI生效时刻,网络配置的重复传输次数中终端未执行完的重复传输的次数。其中,所述目标TB的重复传输次数可通过所述第一DCI配置,也可通过RRC信令配置,还可通过其他方式配置。所述第二DCI的生效起始时间可通过第二DCI指示、通过RRC配置或者通过预设值确定。剩余重复传输资源,指的是用于执行所述剩余重复传输的资源。
在本公开实施例中,所述网络设备可通过第二DCI中的指示信息指示所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
(1)所述第二DCI中包括第一指示字段;所述第二DCI中的指示信息通过第一指示字段指示。
其中,所述第二DCI可以采用协议中规定的任意一种DCI格式实现。所述第一指示字段可以是新增的指示字段,例如,Re-config flag字段等。也即,在这种方式中,网络设备通过第一指示字段来指示终端是否根据第二DCI确定所述目标TB的剩余重复传输资源。例如,如果第一指示字段的值为1,则指示终端根据第二DCI确定所述目标TB的剩余重复传输资源,否则可用于常规的调度。通过这种方式,网络设备可以动态更新剩余重复传输次数的资源配置,提高了调度的灵活性。
(2)所述第二DCI中包括第二指示字段;所述指示信息通过所述第二指示字段的目标状态指示。
其中,所述第二DCI可以采用协议中规定的任意一种DCI格式实现,所述第二指示字段可以是现有的任意的字段。也就是说,在此,通过对DCI中现有字段的目标状态的重新定义,来指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。在本公开实施例中,所述第二指示字段和所述第一指示字段不同。其中,所述第二指示字段可以为MCS字段。
例如,在NDI(New data indicator,新数据指示符)指示HARQ重传的前提下,定义一种MCS状态指示终端根据第二DCI确定所述目标TB的剩余重复传输资源,继续完成剩余重复传输次数。在这种方式中,通过HARQ重传调度时的1种MCS比特状态,支持网络设备动态的更新剩余重复传输次数的资源配置。HARQ重传调度虽然不排除调度任何MCS状态,但是通常只用到MCS最后3、4种状态(指示终端不重新计算TBS(Transport Block Size,传输块大小),利用上一个DCI调度信息计算TBS),因此,可以考虑利用HARQ重传调度中1种不常用的MCS状态,降低重传调度的灵活性,用于指示当前的调度是用于剩余重复次数还是HARQ重传。例如MCS的比特状态为“00000”、“11011”或“11100”时,指示终端第二DCI用于调度剩余重复传输,即根据第二DCI确定所述目标TB的剩余重复传输资源,否则终端执行HARQ重传。
(3)所述第二DCI中包括第三指示字段;所述指示信息通过所述第三
指示字段的目标比特指示。
其中,所述第二DCI可以采用协议中规定的任意一种DCI格式实现,所述第三指示字段可以是现有的任意的字段。也就是说,在此,通过对DCI中现有字段的目标比特的重新定义,来指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。其中,在本公开实施例中,所述第三指示字段和所述第一指示字段不同。
例如,可通过频域资源分配字段(Frequency domain resource assignment)或MCS字段的第X位比特,用于指示第二DCI的调度是否用于剩余重复传输次数,也即,指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。
在本公开实施例中,所述网络设备还可通过第二DCI的格式指示所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
具体的,所述第二DCI的格式为用于配置时域和频域资源的DCI格式,或者,为用于配置频域资源的DCI格式。其中,所述第二DCI的格式可以是DCI 2_0,或者还可以是新定义的DCI格式。
如果所述第二DCI的格式为DCI 2_0,那么,所述第二DCI中包括频域资源分配字段;通过所述第二DCI的格式为DCI 2_0指示所述终端根据第二DCI确定目标TB的剩余重复传输资源。如果是新定义的DCI格式,那么,可通过新定义的DCI格式中的任意字段或者该新定义的DCI格式来指示终端根据第二DCI确定目标TB的剩余重复传输资源。
如果所述第二DCI的格式为DCI 2_0,那么,当所述终端工作于TDD模式时,所述第二DCI还包括时隙格式指示字段;其中,所述时隙格式指示字段用于指示所述传输资源对应的时域资源,所述频域资源分配字段用于指示所述传输资源对应的频域资源。或者,当所述终端工作于双工模式时,所述第二DCI中不包括时隙格式指示字段;所述频域资源分配字段用于指示所述传输资源对应的频域资源。
终端如果收到该第二DCI,那么,终端通过该第二DCI配置的时频域资源执行剩余重复次数的传输,其他配置信息仍然采用第一DCI对应的配置;否则,终端不更新剩余重复传输次数的时频域资源配置。
如果第二DCI为新定义的DCI格式,那么,所述第二DCI包括时域资源分配字段(Time domain resource assignment)和频域资源分配字段(Frequency domain resource assignment),或者,所述第二DCI包括频域资源分配字段;其中,所述时域资源分配字段用于指示所述传输资源对应的时域资源;所述频域资源分配字段用于指示所述传输资源对应的频域资源。其他配置信息复用第一DCI对应的配置。
可选地,如果第二DCI为新定义的DCI格式,所述第二DCI包括第四指示字段,所述第四指示字段用于指示所述第二DCI对应的HARQ process。例如,所述第二DCI中可包括DCI格式中可以包含HARQ process number(HARQ进行序号)字段,用于指示该第二DCI调度对应的HARQ进程。当多个进程有未完成的重复传输时,可以通过该字段实现分别给每个进程重新配置不同的时域、频域资源。
如果第二DCI为新定义的DCI格式,所述第二DCI还可DCI可以指示终端组(UE group)的时域资源和频域资源。所述终端组内的终端的时域资源和/或频域资源不重叠,或者,所述终端组内的终端的时域资源或频域资源完全重叠或相同;或当所述第二DCI指示终端组的频域资源时,所述终端组内的终端的频域资源完全重叠或相同。当所述终端组内的终端的频域资源完全重叠或相同时,可以大大降低所述DCI的比特开销。
如果第二DCI为新定义的DCI格式,所述网络设备还可接收所述终端发送的对于所述第二DCI的确认信息,从而避免当终端没有正确收到这个第二DCI而继续在原资源上进行重复传输,而网络设备理解终端正确收到这个第二DCI并在该终端的原有资源上调度其他终端,导致的其他终端和该终端之间的干扰。
步骤103、所述网络设备根据所述第二DCI确定的剩余重复传输资源接收或发送所述目标TB。
在本公开实施例中,网络设备可在通过第一DCI调度目标TB的重复传输的情况下,向终端发送第二DCI,以通过所述第二DCI中的指示信息或者所述第二DCI的格式指示终端根据所述第二DCI确定所述目标TB的剩余重复传输资源,并根据第二DCI确定的剩余重复传输资源接收或发送所述目标
TB。由此可以看出,利用本公开实施例的方案,可对剩余重复传输的传输资源进行配置,从而解决重复传输资源不可用而导致的传输中断问题,或者使得终端可以及时利用丰富的传输资源或者使得终端获得更有利于传输的资源,进而提高传输效率,节省终端功耗。
参见图2,图2是本公开实施例提供的信息处理方法的流程图,如图2所示,包括以下步骤:
步骤201、终端根据第一DCI执行目标TB的重复传输。
其中,所述目标TB可以是任意的TB。在实际应用中,网络通过第一DCI调度目标TB的新传或者HARQ重传,且可通过第一DCI或者RRC信令配置所述目标TB的重复次数,那么,终端可根据基站的调度接收或者发送所述目标TB。因此,第一DCI为首次调度目标TB的新传或者HARQ重传的DCI,可以采用现有的任意的DCI格式实现。
步骤202、所述终端接收第二DCI。
其中,所述第二DCI为对所述目标TB所在的HARQ process进行调度的DCI。所述第二DCI是在未执行完对目标TB的全部重复传输的情况下接收到的。因此,第二DCI为终端在执行通过所述第一DCI调度的所述目标TB的新传或者HARQ重传的重复传输过程中再次收到的DCI。
步骤203、基于所述第二DCI中的指示信息或者所述第二DCI的格式,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
在此步骤中,终端可基于所述第二DCI中的指示信息,根据所述第二DCI确定所述目标TB的剩余重复传输资源。
(1)所述第二DCI中包括第一指示字段;所述第二DCI中的指示信息通过所述第一指示字段指示。
当所述第一指示字段指示的值为第一预设值时,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。该第一预设值可根据需要设置。
其中,所述第二DCI可以采用协议中规定的任意一种DCI格式实现。所述第一指示字段可以是新增的指示字段,例如,Re-config flag字段等。也即,在这种方式中,网络设备通过第一指示字段来指示终端是否根据第二DCI确定所述目标TB的剩余重复传输资源。例如,如果第一指示字段的值为1,则
终端根据第二DCI确定所述目标TB的剩余重复传输资源,否则可确定该第二DCI用于常规的调度。
(2)所述第二DCI中包括第二指示字段;所述指示信息通过所述第二指示字段的目标状态指示。
当所述第二DCI中的第二指示字段的目标状态指示为预设状态时,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
也就是说,在此,通过对DCI中现有字段的目标状态的重新定义,来指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。其中,所述第二指示字段可以为MCS字段。其中,所述预设状态可根据需要设置。
例如,MCS的比特状态为“00000”时,终端可确定第二DCI用于调度剩余重复传输,即根据第二DCI确定所述目标TB的剩余重复传输资源,否则终端执行HARQ重传。
(3)所述第二DCI中包括第三指示字段;所述指示信息通过所述第三指示字段的目标比特指示。
当所述第二DCI中的第三指示字段的目标比特指示为第三预设值时,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。第三预设值可根据需要设置。
其中,所述第二DCI可以采用协议中规定的任意一种DCI格式实现,所述第三指示字段可以是现有的任意的字段。也就是说,在此,通过对DCI中现有字段的目标比特的重新定义,来指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。
例如,可通过Frequency domain resource assignment字段的第X位比特,用于指示第二DCI的调度是否用于剩余重复传输次数,也即,指示终端根据第二DCI确定所述目标TB的剩余重复传输资源。那么,当第X位比特为1时,终端可根据第二DCI确定所述目标TB的剩余重复传输资源。
在此步骤中,终端可基于所述第二DCI的格式,根据所述第二DCI确定所述目标TB的剩余重复传输资源。
具体的,所述第二DCI的格式为用于配置时域和频域资源的DCI格式,或者,为用于配置频域资源的DCI格式。其中,所述第二DCI的格式可以是
DCI 2_0,或者还可以是新定义的DCI格式。
当所述第二DCI的格式为用于配置时域和频域资源的DCI格式,或者,为用于配置频域资源的DCI格式时,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
也就是说,在这种方式中,当终端确定收到的第二DCI是DCI 2_0格式,或者,是新定义的DCI格式,终端即可确定根据所述第二DCI确定所述目标TB的剩余重复传输资源。
所述第二DCI的格式为DCI 2_0;所述第二DCI中包括频域资源分配字段;通过所述第二DCI的格式为DCI 2_0指示所述终端根据第二DCI确定目标TB的剩余重复传输资源。当终端确定接收到的第二DCI的格式为DCI 2_0时,所述终端根据所述第二DCI确定所述目标TB的剩余重复传输资源。
当所述终端工作于TDD模式时,所述第二DCI还包括时隙格式指示字段;其中,所述时隙格式指示字段用于指示所述传输资源对应的时域资源,所述频域资源分配字段还用于指示所述传输资源对应的频域资源。因此,所述终端还可根据所述时隙格式指示字段确定所述传输资源对应的时域资源,以及根据所述频域资源分配字段确定所述传输资源对应的频域资源。
当所述终端工作于双工模式时,所述第二DCI中不包括时隙格式指示字段;所述频域资源分配字段用于指示所述传输资源对应的频域资源;因此,所述终端还可根据所述频域资源分配字段确定所述传输资源对应的频域资源。
当所述第二DCI为新定义的DCI格式时,所述第二DCI包括时域资源分配字段和频域资源分配字段,或者,所述第二DCI包括频域资源分配字段;其中,所述时域资源分配字段用于指示用于所述传输资源对应的时域资源;所述频域资源分配字段用于指示所述传输资源对应的频域资源。所述终端根据所述时域资源分配字段确定所述传输资源对应的时域资源,以及所述终端根据所述频域资源分配字段确定所述传输资源对应的频域资源;或者,所述终端根据所述频域资源分配字段确定所述传输资源对应的频域资源。
此外,所述第二DCI包括第四指示字段,所述第四指示字段用于指示所述第二DCI对应的HARQ process。
可选地,所述终端还可向所述网络设备发送对于所述第二DCI的确认信
息,从而避免当终端没有正确收到这个第二DCI而继续在原资源上进行重复传输,而网络设备理解终端正确收到这个第二DCI并在该终端的原有资源上调度其他终端,导致的其他终端和该终端之间的干扰。
在以上的实施例中,所述第二DCI的生效起始时间位于目标时刻所在时隙,或者,所述第二DCI的生效起始时间位于所述目标时刻所在时隙之后的第k个时隙;其中,所述目标时刻为所述终端接收到所述第二DCI的时刻;k为大于0的整数。k为第二DCI中指示的定时信息,可动态的配置第二DCI的生效起始时间。当所述第二DCI用于调度PDSCH时,k的取值为所述第二DCI中指示的k0;当所述第二DCI用于调度PUSCH时,k的取值为所述第二DCI中指示的k2。
步骤204、所述终端根据所述目标TB的剩余重复传输资源执行所述目标TB的剩余重复传输。
其中,所述第二DCI为对所述目标TB所在的混合自动重传请求进程HARQ process进行调度的DCI。
在本公开实施例中,网络设备可在通过第一DCI调度目标TB的重复传输的情况下,向终端发送第二DCI,以通过所述第二DCI中的指示信息或者所述第二DCI的格式指示终端根据所述第二DCI确定所述目标TB的剩余重复传输资源,并根据第二DCI确定的剩余重复传输资源接收或发送所述目标TB。由此可以看出,利用本公开实施例的方案,可对剩余重复传输的传输资源进行配置,从而解决重复传输资源不可用而导致的传输中断问题,或者使得终端可以及时利用丰富的传输资源或者使得终端获得更有利于传输的资源,进而提高传输效率,节省终端功耗。
以下结合不同的实施例详细描述本公开实施例的信息处理方法的实现过程。
在本公开的一个实施例中,基站在已有DCI格式的基础上,新增指示字段,并通过该指示字段来指示终端确定目TB的剩余重复传输资源,以及确定是否对用于执行剩余重复传输的传输资源进行更新。其中,已有DCI格式可以理解为协议中规定的DCI格式。
基站向终端发送第一DCI,用于调度目标传输块TB的重复传输。基站
向终端发送第二DCI。具体的,基站在已有DCI格式中的已有字段的基础上,新增指示字段用于承载指示信息,以指示终端是否对用于执行剩余重复传输的传输资源进行更新。该新增的字段例如可以是Repetition-Reconfig flag(重复传输重配标识)字段。终端根据该字段判断第二DCI是否用于调度剩余重复传输次数,例如该字段指示“1”代表第二DCI用于剩余重复传输次的调度,该字段指示“0”代表第二DCI为当前已有的调度,如HARQ重传调度或新传输块调度等。
在本公开的一个实施例中,基站在已有DCI格式(DCI 2_0)的基础上,新增频域资源分配字段,并通过该频域资源分配字段来指示终端是否对用于执行剩余重复传输的传输资源进行更新。
基站向终端发送第一DCI,用于调度目标传输块TB的重复传输。基站向终端发送第二DCI。具体的,基站在已有的DCI 2_0格式中,增加频域资源分配字段。基站通过DCI 2_0动态地配置终端时频域资源。终端如果收到该第二DCI,那么终端通过该第二DCI配置的时频域资源执行剩余重复次数的传输,其他配置信息仍然采用重复传输的传输块的初传或者HARQ重传的DCI对应的配置;否则终端仍然按照重复传输的传输块的初传或者HARQ重传的调度执行。
一种可选地实现方式为,在DCI 2_0增加频域资源分配字段,同时实现调度剩余重复传输次数和对应频域资源的配置。该方式的DCI开销较小,传输可靠性更高。
一种可选地实现方式为,DCI 2_0的字段及功能根据终端所属的双工状态确定,即当终端处于TDD模式下,DCI 2_0为现有的DCI2_0,即包含时隙格式指示字段,用于更新上下行配比,更新时域资源;当处于双工模式下,不包含时隙格式指示字段,包含频域资源指示字段,用于更新频域资源。
在本公开的一个实施例中,在已有的DCI格式的基础上,利用对其中的已有字段的某个状态重新解读或者对已有字段的某个比特重新解读,来指示所述终端根据第二DCI确定所述目标TB的剩余重复传输资源;
可以定义已有DCI中某字段的某种状态用于指示当前DCI(第二DCI)的调度用于剩余重复传输次数。例如在NDI指示HARQ重传的前提下,定
义MCS字段对应的一种MCS状态指示终端当前DCI调度是否用于剩余重复传输次数。
这种方式中,利用HARQ重传调度时的1种MCS比特状态,支持基站动态的更新剩余重复传输次数的资源配置。HARQ重传调度虽然不排除调度任何MCS状态,但是通常只用到MCS最后3、4种状态(指示终端不重新计算TBS,利用上一个DCI调度信息计算TBS),因此可以考虑利用HARQ重传调度中1种不常用的MCS状态(例如对于频谱效率(Spectral efficiency)最高的MCS索引,由于在配置重复传输的情况下,同时配置最高的频谱效率的场景不多),用于指示当前的调度是用于剩余重复次数还是HARQ重传。
例如,如果网络配置给终端的MCS表格不支持调制阶次为8,MCS比特状态‘11100’(MCS索引为28)用于指示当前DCI调度是用于剩余重复传输次数,否则,当前DCI是用于当前已有调度,例如HARQ重传或新传输块调度等;如果网络配置给终端的MCS表格支持调制阶次为8,MCS比特状态‘11011’(MCS索引为27)用于指示当前DCI调度是用于剩余重复传输次数,否则,当前DCI是用于当前已有调度,例如HARQ重传或新传输块调度等。
例如,MCS的比特状态为“00000“指示终端当前DCI用于调度剩余重复传输,否则指示当前DCI用于HARQ重传或新传输块调度等协议已有调度类型。
也可以定义现有DCI中某个字段的某个比特用于指示当前DCI(第二DCI)的调度是否用于剩余重复传输次数。例如Frequency domain resource assignment(频域资源分配)字段的第X位比特用于指示当前DCI的调度是否用于剩余重复传输次数,X为正数。第X位指示“1”代表当前DCI用于剩余重复传输次的调度,第X位指示“0”代表当前DCI为当前已有的调度,如HARQ重传调度或新传输块调度等。当现有Frequency domain resource assignment字段的比特长度出现富余,可以利用该字段的富余比特作为指示字段,从而在不增加DCI开销的情况下,动态调度剩余重复传输次数。
在本公开的一个实施例中,还可通过定义一种新的DCI格式,用于调度剩余重复传输次数。该DCI格式中包含Time domain resource assignment(时域资源分配)和/或Frequency domain resource assignment(频域资源分配)字段,用于指示剩余重复传输次数的时频资源配置。其他配置信息复用调度重复传输的PDCCH对应的配置。终端根据接收的DCI,更新剩余重复次数的时域/频域资源。
终端可以在收到该当前DCI(第二DCI)对应的时隙(slot)开始启用该当前DCI中的资源配置,例如终端在slot n收到该DCI,那么终端可以在slot n启用该DCI中的资源配置;终端也可以在收到该DCI之后的某个时间间隔后启用该DCI,例如的终端在slot n收到该DCI,那么终端在slot+K开始启用该DCI中的资源配置。
可选地,K为协议预定义的某个值。或者该DCI格式中包含K的指示信息,用于动态配置该DCI的生效时间。
可选地,该DCI格式中可以包含HARQ process number字段,用于指示该DCI调度对应的HARQ进程。当终端多个进程有未完成的重复传输时,可以通过该字段实现分别给每个进程重新配置不同的时频域资源。
可选地,终端收到该DCI之后,可向基站发送确认信息,避免当终端没有正确收到这个DCI而继续在原资源上进行重复传输,而基站理解终端正确收到这个DCI并在该终端的原有资源上调度其他终端,导致其他终端和该终端之间的干扰。例如,终端在正确接收该当前DCI之后,通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)反馈1bit确认(ACK)信息,所述1bit ACK信息可以和物理下行共享信道(Physical downlink shared channel,PDSCH)接收(reception)/半持续调度(Semi-Persistent Scheduling,SPS)PDSCH释放(release)的反馈信息复用到一个HARQ-ACK码本(codebook)中。所述1bit ACK在HARQ-ACK codebook的位置可以根据该DCI和所述PUCCH的相对位置确定,也可以预定为HARQ-ACK codebook中的最高/低比特位。
通过以上描述可以看出,利用本公开实施例的方案,对于重配的频域资源大小没有改变,只是改变了时频域资源位置的情况,基站不用因为切换后资源不可用而不能配置给终端,而是可以将终端配置在任意可用资源范围内,切换后如果资源不可用,可再进行资源重配,因此能降低网络调度的复杂度;对于重配的频域资源大小发生改变,和/或时域资源发生改变,基站不仅能降低网络调度的复杂度,还能使得终端及时利用丰富的上行资源(包括时域和频域),降低终端上行传输时延,尤其适合重传(repetition)次数较大的情况。
