具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例,首先对下行控制信息(Downlink Control Information,DCI)传输的处理流程进行说明。如图2所示,DCI的载荷(paload)之后附着一个根据DCI paload生成的循环冗余校验(Cyclical Redundancy Check,CRC),并且还对该CRC加扰无线网络临时标识符(Radio Network Temporary Identity,RNTI),其中,不同的DCI格式(format),不同的DCI paload内容或不同DCI的目的地可以对应不同的RNTI,进一步对附着了加扰RNTI的CRC之后的信息比特进行信道编码,速率匹配,调制和资源映射,以形成物理下行控制信道(Physical Downlink Control Channel,PDCCH)并发送。
其中,调制方式可以包括两相相移键控(Binary Phase Shift Keying,BPSK)、四相相移键控(Quadrature Phase Shift Keying,QPSK)、16种符号的正交幅度调制(16-state quadrature amplitude modulation,16QAM)、64种符号的正交幅度调制(64-state quadrature amplitude modulation,64QAM)中的一种。
其中,资源映射受限于控制资源集(Control Resource Set,CORESET)和搜索空间(searchspace)的配置,即调制后的符号只能在配置的CORESET和对应的searchspace内映射。其中,CORESET可以用于确定DCI可映射区域的频域位置和频域大小,searchspace可以用于确定DCI可映射区域的时域位置。如图3所示为两套CORESET和searchspace的示意图,应注意,CORESET和searchspace是独立配置的,例如,对于图2所示的例子,DCI可以根据CORESET1和搜索空间1(searchspace1)确定一套PDCCH资源,或者也可以根据CORESET1和搜索空间2(searchspace2)确定一套PDCCH资源,本申请并不限于此。
在一些实施例中,可以通过DCI格式,加扰DCI的CRC的RNTI,DCI中的指示域,DCI所在的CORESET或搜索空间确定DCI所调度的数据的优先级。
例如,可以设置不同的DCI格式对应不同的优先级,但是,不同的DCI格式具有各自的优缺点,例如,对于DCI format0_0,DCI payload小,DCI的可靠性高,但是,DCI调度的灵活性差。对于DCI format0_1,DCI payload大,DCI可靠性低,但是,DCI调度灵活性强。通常,网络设备可以根据信道环境,调度策略动态选择合适的DCI format,使得DCI可靠性和调度效率达到最优化。但是,若将优先级与DCI format绑定,DCI format动态选择的灵活性丧失,导致DCI可靠性和调度效率无法兼顾平衡。
并且DCI format的使用资源受限,例如,对于DCI format0_1和DCI format1_1仅能在用户专属搜索空间,当优先级与DCI format0_1或DCI format1_1绑定时,由于DCI可映射资源受限,导致DCI传输容易拥塞,导致DCI的调度延迟。
又例如,可以设置不同的RNTI对应不同的优先级,例如,调制编码方案小区(Modulation and Coding Scheme-Cell-RNTI,MCS-C-RNTI)和小区无线网络临时标识符(Cell Radio Network Temporary Identity,C-RNTI)分别对应不同的优先级,由于所述MCS-C-RNTI和C-RNTI与调制编码方案(Modulation and Coding Scheme,MCS)表格有约定关系,则优先级与MCS表格必然存在约定关系,例如,若MCS-C-RNTI对应高优先级,且只能采用MCS表格2,C-RNTI对应低优先级,且只能采用MCS表格1,由于MCS表格的约束,影响了数据传输的效率和可靠性。
再例如,可以设置DCI中的指示域指示不同的优先级,例如,该指示域可以为新增的指示域,此情况下,可能降低DCI的可靠性,并且新增指示域的DCI只能在用户专属搜索空间传输,公共搜索空间中传输的DCI无法指示优先级。或者,将DCI中的现有的指示域与优先级建立绑定关系,导致现有的指示域指示灵活度降低。例如,通过物理下行共享信道到HARQ反馈时间(Physical Downlink Shared Channel,PDSCH-HARQ_feeback timing)指示优先级,当PDSCH-HARQ_feeback timing取值小于14个符号(symbol),则指示高优先级,否则指示低优先级。这样,当网络设备调度高优先级业务时,PDSCH-HARQ_feeback timing必须采用小于14symbols的配置,限制了高优先级业务的反馈的灵活性。
再例如,若设置DCI所在的搜索空间或CORESET指示不同的优先级,建立搜索空间或CORESET和优先级的绑定关系,会使得DCI的可映射资源受限,导致DCI传输拥塞,进而导致DCI调度延迟。
由上分析可看出,通过单一的信息指示优先级的方式,均有一定的应用局限性,因此,需要一种指示方式,能够灵活指示DCI所调度的数据的优先级。

以下,结合具体实施例,对实施例1和实施例4的具体实现进行说明,其他实施例的实现方式类似,这里不再赘述。
实施例1-1:终端设备可以根据接收第一DCI的搜索空间和第一DCI中的指示域确定所述第一信息的优先级。
例如,若所述终端设备在公共搜索空间检测到所述第一DCI,可以确定第一信息的优先级为第一优先级。可选地,所述第一优先级可以是预定义的,或者网络设备配置的。可选地,作为一个示例,所述第一优先级可以为多个优先级中的最高优先级。
又例如,若终端设备在用户专属搜索空间(UE-Specific SearchSpace)检测到所述第一DCI,可以进一步基于所述第一DCI中的指示域确定第一信息的优先级。
作为一个示例,所述第一DCI中的指示域可以为用于指示优先级的第一指示域,此情况下,所述终端设备可以将所述第一指示域所指示的优先级确定为所述第一信息的优先级。例如,若所述第一指示域指示第一优先级,可以确定所述第一信息的优先级为第一优先级,或者,若所述第一指示域指示第二优先级,可以确定所述第一信息的优先级为第二优先级。
作为另一示例,所述第一DCI中的指示域可以为所述第一DCI中的第二指示域,所述第二指示域可以用于指示除优先级之外的其他信息,例如,所述其他信息可以为时域资源指派(Time domain resource assignment),混合自动请求重传(Hybrid Automatic Repeat reQuest,HARQ)进程号(process number),物理下行共享信道到HARQ反馈时间(Physical Downlink Shared Channel,PDSCH-HARQ_feeback timing)。
可选地,所述第二指示域的不同取值可以用于指示不同的优先级,例如,PDSCH-HARQ_feeback Timing取值为第一值(例如,小于14个symbol),表示所述第一信息的优先级为第一优先级,PDSCH-HARQ_feeback Timing取值为其他值(例如,大于14个symbol),表示所述第一信息的优先级为第二优先级,所述第一优先级高于所述第二优先级。
进一步地,终端设备可以根据所述第一信息的优先级,进行所述第一信息的传输。
作为一个示例,若该第一信息的时域资源和待传输的第二信息的时域资源存在重叠,则所述终端设备可以根据第一信息的优先级和第二信息的优先级,确定优先传输的信息。例如,若第一信息的优先级为第一优先级,所述第二信息的优先级为第二优先级,所述第一优先级高于第二优先级,终端设备可以优先传输该第一信息。这里,所述第二信息可以是第二DCI调度的第二上行数据或第二DCI调度的第二下行数据或所述第二DCI调度的第二下行数据的反馈信息,所述第二信息的优先级的确定方式参考所述第一信息的优先级的确定方式,这里不再赘述。
可选地,若所述第一信息和第二信息都为上行数据,该第一信息的时域资源和所述第二信息的时域资源存在重叠可以为用于承载所述第一信息的第一数据信道和用于承载所述第二信息的第二数据信道的时域资源存在重叠;或者,若所述第一信息和第二信息都为反馈信息,该第一信息的时域资源 和所述第二信息的时域资源存在重叠可以为用于承载所述第一信息的第一控制信道和用于承载所述第二信息的第二控制信道的时域资源存在重叠。
应理解,这里的时域资源重叠可以是部分时域资源重叠,或者也可以是时域资源完全重叠。
在另一些实施例中,终端设备可以根据所述第一信息的优先级,进行所述第一信息的处理。
例如,若所述第一信息的优先级为高优先级,所述终端设备可以采用较快的处理时间处理所述第一信息。
又例如,若所述第一信息为反馈信息,所述终端设备也可以根据所述第一信息的优先级,确定传输所述反馈信息的资源集合或PDSCH_to_HARQ反馈间隔,例如,若所述第一信息的优先级为高优先级,可以确定所述反馈信息的PDSCH_to_HARQ反馈间隔较小,反之,确定PDSCH_to_HARQ反馈间隔较大。
因此,在该实施例1-1中,网络设备可以在用户专属搜索空间通过DCI的指示域灵活指示优先级信息,并且在不改变公共搜索空间的DCI格式的情况下,可以获得确定的优先级信息。
实施例1-2:终端设备可以根据接收第一DCI的搜索空间和第一DCI中的指示域确定所述第一信息的处理时间。
例如,若所述终端设备在公共搜索空间检测到所述第一DCI,可以确定第一信息的处理时间为第一处理时间。可选地,所述第一处理时间可以是预定义的,或者网络设备配置的,例如,2个符号或4个符号等。可选地,作为一个示例,所述第一处理时间可以为多个处理时间中的最短的处理时间。
又例如,若终端设备在用户专属搜索空间(UE-Specific SearchSpace)检测到所述第一DCI,可以进一步基于所述第一DCI中的指示域确定第一信息的处理时间。
作为一个示例,所述第一DCI中的指示域可以为用于指示处理时间的第三指示域,此情况下,所述终端设备可以将所述第三指示域所指示的处理时间确定为所述第一信息的处理时间。例如,若所述第三指示域指示第一处理时间,可以确定所述第一信息的处理时间为第一处理时间,或者,若所述第三指示域指示第二处理时间,可以确定所述第一信息的处理时间为第二处理时间。
作为另一示例,所述第一DCI中的指示域可以为所述第一DCI中的第二指示域,所述第二指示域可以用于指示除处理时间之外的其他信息,例如,时域资源指派(Time domain resource assignment),混合自动请求重传(Hybrid Automatic Repeat reQuest,HARQ)进程号(process number),物理下行共享信道到HARQ反馈时间(Physical Downlink Shared Channel,PDSCH-HARQ_feeback timing)。
可选地,所述第二指示域的不同取值可以用于指示不同的处理时间,例如,PDSCH-HARQ_feeback Timing取值为第一值(例如,小于14个symbol),表示所述第一信息的处理时间为第一处理时间,PDSCH-HARQ_feeback Timing取值为其他值(例如,大于14个symbol),表示所述第一信息的处理时间为第二处理时间,所述第一处理时间小于所述第二处理时间。
进一步地,终端设备可以根据所述第一信息的处理时间,进行所述第一信息的处理。
例如,若所述第一信息的处理时间为第一处理时间,所述终端设备可以采用较快的处理时间处理所述第一信息。
例如,若所述第一信息的处理时间为第二处理时间,所述终端设备可以采用较慢的处理时间处理所述第一信息。
因此,在该实施例1-2中,网络设备可以在用户专属搜索空间通过DCI的指示域灵活指示处理时间,并且在不改变公共搜索空间的DCI格式的情况下,可以获得确定的处理时间信息,便于终端设备采用合适的处理时间进行所述第一信息的处理,提升系统资源利用率,进而能够提升系统性能。

又例如,若终端设备在用户专属搜索空间检测到所述第一DCI,可以进一步加扰所述第一DCI的CRC的RNTI确定第一信息的优先级。
例如,加扰DCI的CRC的RNTI与待传输的信息的优先级可以具有对应关系,该终端设备可以根据加扰该第一DCI的CRC的RNTI,结合该对应关系,确定该第一信息的优先级,可选地,所述对应关系可以是预定义的,或者也可以是网络设备配置的。
作为一个示例,若加扰所述第一DCI的CRC的RNTI为第一RNTI,确定所述第一信息为第一优先级,或者,若加扰所述第一DCI的CRC的RNTI为第二RNTI,确定所述第一信息为第二优先级。
可选地,所述第一优先级是预定义的,或网络设备配置的;所述第二优先级是预定义的,或网络设备配置的。
在一些实施例中,所述第一优先级为高优先级,所述第二优先级为低优先级。
作为一个示例,所述第一RNTI为调制编码方案小区RNTI(Modulation and Coding Scheme-Cell-RNTI,MCS-C-RNTI),所述第二RNTI可以为除MCS-C-RNTI之外的其他RNTI,例如,所述第二RNTI可以为小区无线网络临时标识符(Cell Radio Network Temporary Identity,C-RNTI),或者,反过来指示亦可。
假设待传输的信息的优先级包括第一优先级和第二优先级,可以利用现有的RNTI分别指示该第一优先级和第二优先级,例如,利用现有一种RNTI用于指示第一优先级,现有的另一种RNTI用于指示第二优先级。或者,若具有更多种优先级,可以采用现有的更多个RNTI进行指示。
作为另一示例,所述第二RNTI为MCS-C-RNTI或C-RNTI,所述第一RNTI为除MCS-C-RNTI和C-RNTI之外的其他RNTI。
假设待传输的信息的优先级包括第一优先级和第二优先级,可以新增RNTI用于指示第一优先级,利用现有的一个RNTI或多个指示第二优先级;或者,若具有更多种优先级,可以新增多个RNTI或利用现有的更多种RNTI指示该多种优先级。
应理解,在本申请实施例中,RNTI和优先级的对应关系可以是一对一,即一个RNTI指示一种优先级,或者也可以是多对一,即多个RNTI指示一种优先级,本申请实施例对此不作限定。
进一步地,终端设备可以根据所述第一信息的优先级,进行所述第一信息的处理或传输。具体实现参考实施例1-1的相关描述,这里不再赘述。
因此,在该实施例1-3中,网络设备可以在用户专属搜索空间通过加扰DCI的CRC的RNTI灵活指示优先级信息,并且在不改变公共搜索空间的DCI格式的情况下,仍然能够获得确定的优先级信息。
实施例1-4:终端设备可以根据接收第一DCI的搜索空间和加扰所述第一DCI的CRC的RNTI确定所述第一信息的处理时间。
例如,若所述终端设备在公共搜索空间检测到所述第一DCI,可以确定第一信息的处理时间为第一处理时间。
又例如,若终端设备在用户专属搜索空间检测到所述第一DCI,可以进一步加扰所述第一DCI的CRC的RNTI确定第一信息的处理时间。
