Description

一种信道资源集的指示方法、终端设备及网络设备 技术领域
本发明涉及信息处理技术领域,尤其涉及一种信道资源集的指示方法、终端设备及网络设备。
背景技术
在LTE系统中,某个终端的上行控制信道(PUCCH)的资源可以采用两步法指示:基站通过RRC信令为终端配置一个包含多个候选频域资源的资源集;再通过下行控制信息DCI从资源集中为该终端指定一个频域资源,用于该终端传输PUCCH。在5G NR的技术讨论中,也将采用资源集的方法分配PUCCH资源,基站可以通过RRC信令为终端配置一个或多个多维度的资源集,每个资源集包含多个时域、频域、码域多维度的PUCCH资源,然后基站通过DCI从资源集中为该终端指定一个多维度资源,用于该终端传输PUCCH。
目前,5G NR中将支持两种调度类型:基于时隙的调度和基于符号的调度。但是,需要统一配置一个或一套PUCCH资源集,如此就会限制针对每种调度类型或相应的DCI Format的资源调度灵活性,并带来更大的RRC信令和DCI信令开销。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种信道资源集的指示方法,应用于终端设备,如图1所示,包括:
步骤101:确定至少两个资源集;其中,所述至少两个资源集中至少包 括第一资源集和第二资源集;其中,不同资源集分别对应不同的解调参考信号DMRS映射类型;
步骤102:从所述至少两个资源集中的一个资源集确定第一资源;
步骤103:基于所述第一资源传输第一信道;
其中,所述基于所述第一资源传输第一信道,包括:
如果基于第一资源集确定第一资源,则第一信道采用所述第一资源集所对应的第一DMRS映射类型传输;或,第一信道传输针对第二信道的HARQ-ACK信息且所述第二信道采用第一DMRS映射类型传输;
如果基于第二资源集确定第一资源,则第一信道采用所述第二资源集所对应的第二DMRS映射类型传输;或第一信道传输针对第二信道的HARQ-ACK信息且所述第二信道采用第二DMRS映射类型传输。
这里,所述终端设备可以为手机、平板电脑等能够接入到通信网络的设备。
终端设备所包含的至少两个资源集中,每个资源集包含至少一个时域、和/或、频域、和/或、码域资源。
另外,需要理解的是,不同的资源集中包含的至少一个时域、和/或、频域、和/或、码域资源至少部分不同;或者,不同的资源集中包含的至少一个时域、和/或、频域、和/或、码域资源完全不同。
终端确定至少两个资源集的方式可以包括:
方式一、
所述终端设备基于预设的信息确定第一资源集和/或第二资源集的配置。
具体来说,终端可以通过预定义的信息确定第一资源集、和/或、第二资源集的配置。
其中,预设的信息或者预定义的信息,可以为在终端侧根据其他操 作获取的信息进行预设。
方式二、
所述终端设备根据网络侧发来的第一信令确定至少两个资源集的配置。
具体的,终端可以根据网络设备发送的第一信令确定第一资源集、和/或、第二资源集的配置。
其中,所述第一信令为RRC控制信令、或、系统信息SI。
进一步地,前述步骤102中,所述从所述至少两个资源集中的一个资源集确定第一资源也可以包括多种处理:
处理1、
所述终端设备根据网络侧发来的第一控制信息,从所述至少两个资源集中的一个资源集确定第一资源;
其中,所述第一控制信息,包括:第一资源在至少两个资源集中的一个资源集中的编号信息。
具体来说,当至少两个资源集包含有第一资源集以及第二资源集的时候,终端根据网络设备发送的第一控制信息,从第一资源集、或、第二资源集中确定第一资源。
其中,所述第一控制信息,包括:第一资源在第一资源集、或、第二资源集中的编号信息。
处理2、
所述从所述至少两个资源集中的一个资源集确定第一资源,包括:
所述终端设备根据第一控制信息的格式、或者、所述终端设备根据网络侧发来的DMRS映射类型的指示信息,从所述至少两个资源集中的一个资源集确定第一资源。
其中,第一控制信息的格式可以为DCI的格式。
也就是说,终端可以根据所述第一控制信息的格式(如DCI格式)或确定采用网络设备发送的解调参考信号映射类型的指示信息,确定第一资源基于第一资源集确定、还是基于第二资源集确定。
前述两种处理方式中,所述第一控制信息均可以为下行控制信息DCI和/或媒体访问控制MAC控制元素CE。
所述第一信道采用所述第一资源集所对应的第一DMRS映射类型传输时,或,第一信道传输针对第二信道的HARQ-ACK信息且所述第二信道采用第一DMRS映射类型传输时;所述方法还包括:
根据传输该信道的时隙的起始符号确定至少一个DMRS符号的位置。或者,采用所述第一解调参考信号映射类型传输的第一信道或第二信道,以时隙、和/或、符号为单位指示时域资源。
其中,所述至少一个解调参考信号符号的位置,为所述时隙的第三个时域符号或者第四个时域符号。
所述第一信道采用所述第二资源集所对应的第二DMRS映射类型传输;或第一信道传输针对第二信道的HARQ-ACK信息且所述第二信道采用第二DMRS映射类型传输;所述方法还包括:
采用所述第二DMRS映射类型传输的第一信道或第二信道中,根据一组符号的起始符号确定至少一个解调参考信号符号的位置。
具体的,采用所述第二解调参考信号映射类型传输的信道中,至少一个解调参考信号符号的位置根据一组符号的起始符号确定。所述一组符号为所述数据信道及其解调参考信号传输的符号。所述至少一个解调参考信号符号为以下之一:
所述一组符号中的第一个符号;
所述一组符号中的位于中央范围的一个符号;
所述一组符号中的奇数符号;
所述一组符号中的偶数符号。
其中,所述位于中央范围,可以认为是位于全部符号的中间符号处,比如,如果总符号数是偶数N,可能是第N/2个或第N/2+1个符号,为N/2还是N/2+1中的哪一种,取决于选取奇数符号或偶数符号。
或者,以符号为单位指示时域资源。
采用所述第二解调参考信号映射类型传输的信道以符号为单位指示时域资源。
可见,通过采用上述方案,就能够针对不同的调度类型和DMRS映射类型配置不同的资源集,从而实现针对不同的调度类型和DMRS映射类型分别优化其候选资源,进而每次调度时基于网络侧信息(如调度类型、DMRS映射类型的指示信息、与之对应DCI格式、DCI等)进行资源集的选取及具体资源的确定,并在确定的资源上传输信道即可。如此,避免了现有技术中“为多种调度类型或相应的DCI Format统一配置一个或一套PUCCH资源集”导致的每种调度类型的资源调度灵活性受到限制的问题,本发明的方案能够提升每种调度类型各自的资源调度灵活性,实现信道传输更高效的资源利用率和传输性能,并且避免更大的信令开销。
另外,由于根据已有的网络侧信息(如DCI格式或解调参考信号映射类型或调度类型的指示信息)即可确定第一资源基于第一资源集确定、还是基于第二资源集确定,不需要额外的信令指示,从而进一步的降低信令传输开销。
实施例二、
本实施例针对两种DMRS映射类型分别配置PDSCH资源集,具体的:
两种PDSCH DMRS映射类型分别为DMRS映射类型A(如图2所 示)和DMRS映射类型B(如图3所示):
采用DMRS映射类型A的PDSCH中,DMRS符号的位置是以PDSCH所在的时隙的起始符号为参考位置确定的(如第一DMRS符号总是位于时隙的第3个或第4个符号),DMRS映射类型A主要用于基于时隙的调度类型(slot-based scheduling),即以时隙为单位调度;采用DMRS映射类型B的PDSCH中,DMRS符号的位置是以PDSCH占用的符号中的第一个符号为参考位置确定的(如第一DMRS符号总是位于PDSCH占用的第1个符号),DMRS映射类型B主要用于基于非时隙的调度类型(non-slot-based scheduling),即以符号为单位调度。
本实施例针对DMRS映射类型A(slot-based scheduling)和DMRS映射类型B(non-slot-based scheduling)分别配置一个PDSCH资源集:PDSCH资源集A和PDSCH资源集B,分别包含不同的资源。如本实施例所示,PDSCH资源集A包含4种数量的时隙的资源,而只包含2种起始符号的资源,且不包含不同符号数量的资源;PDSCH资源集B包含4种起始符号不同的资源,而不包括不同数量时隙的资源,但包含2种符号数量的资源。

采用此方案,PDSCH资源集A和PDSCH资源集B可以分别针对slot-based scheduling和non-slot-based scheduling优化资源的配置。slot-based scheduling的PDSCH往往需要连续多个时隙的传输,以获得更好的网络覆盖,更适合使用资源集A,non-slot-based scheduling的PDSCH往往需要1-2个符号长度的传输长度,以实现低时延的传输,更适合使用资源集B。相对DMRS映射类型A(slot-based scheduling)和DMRS映射类型B(non-slot-based scheduling)共用一个资源集,可以实现更好的调度灵活性,并降低每个资源池中资源的数量,从而在用DCI指示资源池中的资源编号时,可以降低DCI的信令开销。
实施例三、
本实施例针对两种调度类型分别配置PUSCH资源集。
两种PUSCH的调度类型(如图4、5所示):采用基于时隙的调度类型(slot-based scheduling),即以时隙为单位调度;采用基于非时隙的调度类型(non-slot-based scheduling),即以符号为单位调度。
本实施例针对DMRS映射类型A(slot-based scheduling)和DMRS映射类型B(non-slot-based scheduling)分别配置一个PUSCH资源集:PUSCH资源集A和PUSCH资源集B,分别包含不同的资源。如本实施例所示,PUSCH资源集A包含4种数量的时隙的资源,而只包含2种起始符号的资源,且不包含不同符号数量的资源;PUSCH资源集B包含4 种起始符号不同的资源,而不包括不同数量时隙的资源,但包含2种符号数量的资源。

采用此方案,PUSCH资源集A和PUSCH资源集B可以分别针对slot-based scheduling和non-slot-based scheduling优化资源的配置。slot-based scheduling的PUSCH往往需要连续传输多个时隙,以获得更好的网络覆盖,更适合使用资源集A,non-slot-based scheduling的PUSCH往往需要1-2个符号长度的传输长度,以实现低时延的传输,更适合使用资源集B。相对slot-based scheduling和non-slot-based scheduling共用一个资源集,可以实现更好的调度灵活性,并降低每个资源池中资源的数量,从而在用DCI指示资源池中的资源编号时,可以降低DCI的信令开 销。
实施例四、
本实施例针对承载两种DMRS映射类型的PDSCH的对应的HARQ-ACK的PUCCH分别配置两种资源集。
两种PDSCH DMRS映射类型分别为DMRS映射类型A(如图2所示)和DMRS映射类型B(如图3所示):采用DMRS映射类型A的PDSCH中,DMRS符号的位置是以PDSCH所在的时隙的起始符号为参考位置确定的(如第一DMRS符号总是位于时隙的第3个或第4个符号),DMRS映射类型A主要用于基于时隙的调度类型(slot-based scheduling),即以时隙为单位调度;采用DMRS映射类型B的PDSCH中,DMRS符号的位置是以PDSCH占用的符号中的第一个符号为参考位置确定的(如第一DMRS符号总是位于PDSCH占用的第1个符号),DMRS映射类型B主要用于基于非时隙的调度类型(non-slot-based scheduling),即以符号为单位调度。
本实施例中,针对承载与采用DMRS映射类型A(slot-based scheduling)和DMRS映射类型B(non-slot-based scheduling)的PDSCH对应的HARQ-ACK的PUCCH,分别配置一个PUCCH资源集:PUCCH资源集A和PUCCH资源集B,分别包含不同的资源。如本实施例所示,PUCCH资源集A包含4种数量的时隙的资源,而只包含2种起始符号的资源,且不包含不同符号数量的资源;PUCCH资源集B包含4种起始符号不同的资源,而不包括不同数量时隙的资源,但包含2种符号数量的资源。

采用此方案,PUCCH资源集A和PUCCH资源集B可以分别针对采用slot-based scheduling的PDSCH对应的HARQ-ACK PUCCH和采用non-slot-based scheduling的PDSCH对应的HARQ-ACK PUCCH优化资源的配置。slot-based scheduling的PDSCH往往需要连续多个时隙的PUCCH承载其HARQ-ACK,以获得更好的网络覆盖,更适合使用资源集A,non-slot-based scheduling的PDSCH往往需要1-2个符号长度的PUCCH承载其HARQ-ACK,以实现低时延的HARQ-ACK反馈,更适合使用资源集B。相对上述两种PUCCH共用一个资源集,可以实现更好的调度灵活性,并降低每个资源池中资源的数量,从而在用DCI指示资源池中的资源编号时,可以降低DCI的信令开销。
实施例五、
如图6所示,本实施例提供确定资源集及从资源集中确定信道的传输资源的流程,具体包括:
首先终端设备根据网络侧(比如网络设备)发来的RRC信令、系统信息、或预定义的配置,确定用于DMRS映射类型A的资源集A,以及用于DMRS映射类型B的资源集B;
所述终端设备接收网络侧发来的DCI或MAC CE;基于所述DCI或MAC CE中的指示信息,确定本次调取的信道(即前述第一信道)基于DMRS映射类型A或DMRS映射类型B;进而用于确定采用资源集A或资源集B中的信道资源;
当确定采用映射类型A时,根据DCI或MAC CE的指示,在资源集A中确定信道的所用资源,采用确定的资源和对应的DMRS映射类型A传输该信道;
当确定采用映射类型B时,根据DCI或MAC CE的指示,在资源集B中确定信道的所用资源,采用确定的资源和对应的DMRS映射类型B传输该信道。
本发明提出了一种通过DCI format和调度类型隐性指示控制信道或数据信道资源集的方法,可以支持针对不同DCI format或调度类型采用不同的信道资源集,以在不增加控制信令开销的前提下,提高信道资源调度的灵活性。
实施例六、
本发明实施例提供了一种信道资源集的指示方法,应用于网络设备,如图7所示,包括:
步骤701:为终端设备配置至少两个资源集;
步骤702:指示所述终端设备从至少两个资源集中的一个资源集中选取第一资源;
其中,所述至少两个资源集中至少包括第一资源集和第二资源集;其中,不同资源集分别对应不同的解调参考信号DMRS映射类型。
另外,需要理解的是,不同的资源集中包含的至少一个时域、和/或、频域、和/或、码域资源至少部分不同;或者,不同的资源集中包含的至少一个时域、和/或、频域、和/或、码域资源完全不同。
其中,所述第一信道为物理下行共享信道PDSCH、物理上行共享信道PUSCH或物理上行控制信道PUCCH。所述第二信道为物理下行共享信道PDSCH。
为终端确定至少两个资源集的方式可以包括:
向所述终端设备发送第一信令,以配置至少两个资源集的配置。
网络设备可以向终端设备发送的第一信令确定第一资源集、和/或、第二资源集的配置。
网络设备向终端发送第一信令,配置第一资源集、和/或、第二资源集的信息。所述第一资源集、和/或、第二资源集配置还包括其中每个资源的编号信息。
其中,所述第一信令为RRC控制信令、或、系统信息SI。
进一步地,指示终端设备从至少两个资源集中选取得到第一资源的方式,可以包括:
向所述终端设备发送第一控制信息,以通过所述第一控制信息从所述至少两个资源集中的一个资源集确定第一资源;
其中,所述第一控制信息,包括:第一资源在第一资源集、或、第二资源集中的编号信息。
其中,采用与解调参考信号映射类型相对应的格式发送所述第一控制信息。
所述第一控制信息,包括:第一资源在至少两个资源集中的一个资源集中的编号信息。
具体来说,当至少两个资源集包含有第一资源集以及第二资源集的 时候,终端根据网络设备发送的第一控制信息,从第一资源集、或、第二资源集中确定第一资源。
其中,所述第一控制信息,包括:第一资源在第一资源集、或、第二资源集中的编号信息。
所述第一控制信息为下行控制信息DCI和/或媒体访问控制MAC控制元素CE。
另外,网络侧指示第一资源的方式还可以为:网络设备采用与相应的解调参考信号映射类型相对应的格式(如DCI格式)发送第一控制信息或向终端发送解调参考信号映射类型的指示信息,指示终端从第一资源集还是第二资源集中确定第一资源。相应的,所述终端设备根据第一控制信息的格式、或者、所述终端设备根据网络侧发来的DMRS映射类型的指示信息,从所述至少两个资源集中的一个资源集确定第一资源。
其中,第一控制信息的格式可以为DCI的格式。
也就是说,终端可以根据所述第一控制信息的格式(如DCI格式)或确定采用网络设备发送的解调参考信号映射类型或调度类型的指示信息,确定第一资源基于第一资源集确定、还是基于第二资源集确定。
可见,通过采用上述方案,就能够针对不同的调度类型和DMRS映射类型配置不同的资源集,从而实现针对不同的调度类型和DMRS映射类型分别优化其候选资源,进而每次调度时基于网络侧信息(如调度类型、DMRS映射类型的指示信息、与之对应DCI格式、DCI等)进行资源集的选取及具体资源的确定,并在确定的资源上传输信道即可。如此,避免了现有技术中“为多种调度类型或相应的DCI Format统一配置一个或一套PUCCH资源集”导致的每种调度类型的资源调度灵活性受到限制的问题,本发明的方案能够提升每种调度类型各自的资源调度灵活性,实现信道传输更高效的资源利用率和传输性能,并且避免更大的信令开 销。
另外,由于根据已有的网络侧信息(如DCI格式或解调参考信号映射类型或调度类型的指示信息)即可确定第一资源基于第一资源集确定、还是基于第二资源集确定,不需要额外的信令指示,从而进一步的降低信令传输开销。

具体来说,终端可以通过预定义的信息确定第一资源集、和/或、第二资源集的配置。
其中,预设的信息或者预定义的信息,可以为在终端侧根据其他操作获取的信息进行预设。
方式二、
处理单元81,根据网络侧发来的第一信令确定至少两个资源集的配置。
具体的,终端可以根据网络设备发送的第一信令确定第一资源集、和/或、第二资源集的配置。
其中,所述第一信令为RRC控制信令、或、系统信息SI。
进一步地,所述从所述至少两个资源集中的一个资源集确定第一资源也可以包括多种处理:
处理1、
处理单元81,根据网络侧发来的第一控制信息,从所述至少两个资源集中的一个资源集确定第一资源;
其中,所述第一控制信息,包括:第一资源在至少两个资源集中的一个资源集中的编号信息。

处理2、
处理单元81,根据第一控制信息的格式、或者、所述终端设备根据网络侧发来的DMRS映射类型的指示信息,从所述至少两个资源集中的一个资源集确定第一资源。
其中,第一控制信息的格式可以为DCI的格式。
也就是说,终端可以根据所述第一控制信息的格式(如DCI格式)或确定采用网络设备发送的解调参考信号映射类型的指示信息,确定第一资源基于第一资源集确定、还是基于第二资源集确定。
前述两种处理方式中,所述第一控制信息均可以为下行控制信息DCI和/或媒体访问控制MAC控制元素CE。
所述第一信道采用所述第一资源集所对应的第一DMRS映射类型传输时,或,第一信道传输针对第二信道的HARQ-ACK信息且所述第二信道采用第一DMRS映射类型传输时;所述方法还包括:

其中,所述位于中央范围,可以认为是位于全部符号的中间符号处,比如,如果总符号数是偶数N,可能是第N/2个或第N/2+1个符号,为N/2还是N/2+1中的哪一种,取决于选取奇数符号或偶数符号。
或者,以符号为单位指示时域资源。
采用所述第二解调参考信号映射类型传输的信道以符号为单位指示时域资源。
可见,通过采用上述方案,就能够针对不同的调度类型和DMRS映射类型配置不同的资源集,从而实现针对不同的调度类型和DMRS映射类型分别优化其候选资源,进而每次调度时基于网络侧信息(如调度类型、DMRS映射类型的指示信息、与之对应DCI格式、DCI等)进行资源集的选取及具体资源的确定,并在确定的资源上传输信道即可。如此,避免了现有技术中“为多种调度类型或相应的DCI Format统一配置一个或一套PUCCH资源集”导致的每种调度类型的资源调度灵活性受到限制的问题,本发明的方案能够提升每种调度类型各自的资源调度灵活性,实现信道传输更高效的资源利用率和传输性能,并且避免更大的信令开销。
另外,由于根据已有的网络侧信息(如DCI格式或解调参考信号 映射类型或调度类型的指示信息)即可确定第一资源基于第一资源集确定、还是基于第二资源集确定,不需要额外的信令指示,从而进一步的降低信令传输开销。
