具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。

应该知道的是,为了方面描述,本发明实施例中,多个载波或BWP是指多个载波或者多个BWP;各个载波或BWP是指各个载波或者各个BWP;多个载波组或BWP组是指多个载波组或者多个BWP组;单载波或BWP是指单载波或者单BWP。
如图1所示,本发明实施例的一种资源确定方法,应用于用户侧设备,包括:
步骤101,获取下行控制信息DCI的时域资源指示信息,所述时域资源指示信息支持调度多个载波或部分带宽BWP。
本步骤中,DCI的时域资源指示信息支持调度多个载波或BWP,并且能够调度单载波或BWP。因此,通过该步骤,获取到DCI的时域资源指示信息,了解到网络侧设备的调度,进而执行下一步。
步骤102,根据所述时域资源指示信息,确定多个载波或BWP上的调度时域资源。
本步骤中,在步骤101获取到的支持调度多个载波或BWP的时域资源指示信息后,根据该时域资源指示信息,确定对应该时域资源指示信息在多个载波或BWP上的调度时域资源。
故,按照步骤101和步骤102,应用本发明实施例方法的用户侧设备,在获取到DCI的时域资源指示信息后,因该时域资源指示信息支持调度多个载波或BWP,则能够确定在多个载波或BWP上的调度时域资源,如此,可实现一个DCI调度多个载波或BWP,有效减少调度过程中PDCCH的开销。
例如,应用于DSS场景,网络侧设备生成携带时域资源指示信息的DCI并发送,因该时域资源指示信息支持调度多个载波或BWP,用户侧设备接收到该DCI后,就能够获取到该时域资源指示信息,从而确定多个载波或BWP上的调度时域资源。
应该知道的是,DCI携带的信息会通过对应域实现。因此,可选地,该实施例中,步骤101包括:
根据DCI调度的候选资源的配置信息,确定所述时域资源指示信息在所述DCI对应的第一指示域;
根据所述第一指示域,得到所述时域资源指示信息。
这里,DCI调度的候选资源的配置信息可通过配置(如高层信令配置)或者预定义等方式获取,则用户侧设备首先根据该配置信息确定时域资源指示信息在所述DCI对应的第一指示域,然后由该第一指示域进一步得到时域资源指示信息。
可选地,所述第一指示域中,各载波或BWP对应的子域按照第一标识的顺序进行排列;或者,
各载波或BWP对应的子域为各自的时域资源指示分配高或低位。
其中,该第一标识可以是小区身份标识(Identifier,ID),或者,载波指示符(Carrier Indicator Field,CIF),或者,BWP ID。在按照第一标识顺序进行排序时,第一标识从大到小进行排序,也可从小到大进行排序,此时,第一指示域中,各载波或BWP对应的子域的大小可以相同,也可以不同。另外,还可以在第一指示域中,各载波或BWP对应的子域为各自的时域资源指示分配预设位置,优选高位或者低位,例如DCI调度cell1,并在第一指示域中cell1 对应的子域为该cell1的时域资源指示分配高位,假设第一指示域中cell1对应的子域为5bit,该cell1的时域资源指示仅需2bit,则在第一指示域中cell1对应的5bit子域中使用高2bit进行该cell1的时域资源指示。
可选地,该实施例中,所述根据DCI调度的候选资源的配置信息,确定所述时域资源指示信息在所述DCI对应的第一指示域,包括:

将所有第二指示域的大小的总和作为所述第一指示域的大小;或者,
将所有第二指示域中最大第二指示域的大小作为所述第一指示域的大小。
如此,在根据候选资源中各个载波或BWP的配置信息,获得各个载波或BWP对应的第二指示域的大小后,可将所有第二指示域的大小的总和作为第一指示域的大小,即DCI调度各载波或BWP的时域资源分配相关域独立,则优选该第一指示域中各载波或BWP对应的子域按照第一标识的顺序进行排列。以小区ID为例,假设DCI可调度Cell 1和Cell 2,因根据Cell 1和Cell 2上的配置得到Cell 1对应的时域资源分配相关域即第二指示域大小为S 1,Cell 2对应的第二指示域大小为S 2,则该DCI中第一指示域大小为S 1+S 2,而在该第一指示域中,前S 1个bit为Cell 1对应的子域(时域分配相关域),后S 2个bit为Cell 2对应的子域。
另外,还可将所有第二指示域中最大第二指示域的大小作为第一指示域的大小,即DCI调度各载波或BWP的时域资源分配相关域对于各载波或BWP进行共享,则优选该第一指示域中各载波或BWP对应的子域为各自的时域资源指示分配高或低位。以小区ID为例,假设DCI可调度Cell 1和Cell 2,因根据Cell 1和Cell 2上的配置得到Cell 1对应的第二指示域大小为S 1,Cell 2对应的第二指示域大小为S 2,则该DCI中第一指示域大小为max(S 1,S 2),而在该第一指示域中,Cell 1对应的子域为其时域资源指示分配为高(或低)S 1bit,Cell 2对应的子域为其时域资源指示分配相关域为高(或低)S 2bit。故,假设S 1>S 2,Cell 1对应的子域为其时域资源指示分配为高S 1bit,Cell 2 对应的子域为其时域资源指示分配相关域为低S 2bit,则在DCI调度Cell 1的情况下,DCI的第一指示域大小为S 1bit,且第一指示域的高S 1bit为Cell 1的时域资源指示;在DCI调度Cell 2的情况下,DCI的第一指示域大小为S 1bit,且S 1bit的低S 2bit为Cell 2的时域资源指示。当然,第一指示域中各载波或BWP对应的子域为各自的时域资源指示的分配可均是高位或者均是低位。
此外,考虑到候选资源包括多个载波组或BWP组,则针对多个载波组或BWP组,可选地,所述根据DCI调度的候选资源的配置信息,确定所述时域资源指示信息在所述DCI对应的第一指示域,包括:
在所述候选资源包括多个载波组或BWP组的情况下,根据所述多个载波组或BWP组的配置信息,获得各个载波组或BWP组对应的第三指示域的大小;
根据所述第三指示域的大小,确定所述第一指示域的大小。
可选地,所述根据所述第三指示域的大小,确定所述第一指示域的大小,包括:
将所有第三指示域中最大第三指示域的大小作为所述第一指示域的大小;或者,
根据公式L=S MAX*N得到所述第一指示域的大小L,其中S MAX为所述多个载波组或BWP组中最大的单载波或BWP指示域的大小,N为所述候选资源中多个载波组或BWP组的最大载波或BWP数量;或者,
将所述多个载波组或BWP组中最大的单载波或BWP指示域的大小作为所述第一指示域的大小。
如此,在根据多个载波组或BWP组的配置信息,获得各个载波组或BWP组对应的第三指示域的大小后,可将所有第三指示域中最大第三指示域的大小作为第一指示域的大小。当同一大小的DCI可调度多个载波组或BWP组,则该第一指示域中各载波或BWP对应的子域可按照第一标识的顺序进行排列。其中,若第一指示域在排列后具有剩余比特,则剩余比特为无效比特,可设置为全零。或者,该第一指示域中各载波或BWP对应的子域可为各自的时域资源指示分配高或低位。
例如,DCI可调度载波组1(包括Cell 1和Cell 2)和载波组2(包括Cell 3和Cell 4),由2个载波组各自的配置信息,获得载波组1对应的第三指示域的大小为5bit(其中Cell 1为2bit,Cell 2为3bit),载波组2对应的第三指示域的大小为10bit(其中Cell 3为4bit,Cell 4为6bit),则第一指示域的大小为10bit。因此,若第一指示域中各载波或BWP对应的子域按照第一标识的顺序进行排列,则对于载波组1,第一指示域的前2bit为Cell 1对应的子域,后3bit为Cell 1对应的子域;对于载波组2,第一指示域的前4bit为Cell 3对应的子域,后6bit为Cell 4对应的子域。这样,当DCI调度Cell 1和Cell 2时,DCI的第一指示域的10bit中,前2bit为Cell 1对应的子域(用于Cell 1的调度),之后的3bit为Cell 2对应的子域最后5可设置为全零。
另外,还可将多个载波组或BWP组中最大的单载波或BWP指示域的大小作为第一指示域的大小。DCI可调度的多个载波组或BWP组的各个载波或BWP所需的时域资源分配相关域(即单载波或BWP指示域)大小为S 1,S 2,…,S K,其中K为DCI可调度的多个载波组或BWP组中所有载波或BWP的总数,则第一指示域的大小为S max,S max=max(S 1,S 2,…,S K)。当同一大小的DCI可调度多个载波组或BWP组,则优选该第一指示域中各载波或BWP对应的子域为各自的时域资源指示分配高或低位。例如,DCI可调度载波组1(包括Cell 1和Cell 2)和载波组2(包括Cell 3和Cell 4),由各个载波或BWP的配置信息,获得Cell 1为2bit,Cell 2为3bit,Cell 3为4bit,Cell 4为6bit,则第一指示域的大小为6bit。假设第一指示域中各载波或BWP对应的子域为各自的时域资源指示分配均是高位,则当DCI调度Cell 1和Cell 2,DCI的第一指示域的6bit中,前2bit为Cell 1对应的子域度,之后3bit为Cell2对应的子域,最后1bit为无效比特,可设置为零。
或者,根据公式L=S MAX*N得到第一指示域的大小L,N为候选资源中多个载波组或BWP组的最大载波或BWP数量。当同一大小的DCI可调度多个载波组或BWP组,则该第一指示域中各载波或BWP对应的子域按照第一标识的顺序进行排列,其中,各载波或BWP对应的子域大小可均为S MAX bit,每S MAX bit的高S ibit或者低S i bit对应第i个载波或BWP。另外,该第一指示域中各载波或BWP对应的子域大小也可不同,各载波或BWP对应的子域 大小等于其时域资源指示的大小。
例如,DCI可调度载波组1(包括Cell 1和Cell 2)和载波组2(包括Cell 3和Cell 4),由各个载波或BWP的配置信息,获得Cell 1为2bit,Cell 2为3bit,Cell 3为4bit,Cell 4为6bit,则第一指示域的大小为10*2bit=20bit。第一指示域中各载波或BWP对应的子域按照第一标识的顺序进行排列,则当DCI调度Cell 1和Cell 2,一方面,DCI的第一指示域的20bit中,前10bit为Cell 1对应的子域,后10bit为Cell 2对应的子域,并且,前10bit中仅使用高2bit或者低2bit进行Cell 2的时域资源指示,后10bit中仅使用高3bit或者低3bit进行Cell 2的时域资源指示;另一方面,DCI的第一指示域的20bit中,可使用连续的bit进行小区的时域资源指示,各小区对应的子域直接对小区的时域资源指示,则20bit中前2bit为Cell 1对应的子域,直接进行Cell 2的时域资源指示,之后的3bit为Cell 2对应的子域,进行Cell 2的时域资源指示,如此,最后的15bit为无效比特,可设置为全零。
可选地,该实施例中,所述根据DCI调度的候选资源的配置信息,确定所述时域资源指示信息在所述DCI对应的第一指示域,包括:
根据所述候选资源中参考载波或BWP的配置信息,获得所述第一指示域的大小。
这里,配置或预定义等方式设置了参考载波或BWP,通过参考载波或BWP的配置信息来得到第一指示域的大小。其中,参考载波或BWP可以是辅小区Pcell,cell ID最小或最大的cell或BWP,子载波间隔(Subcarrier Spacing,SCS)最小或最大的cell或BWP。
可选地,该实施例中,所述根据DCI调度的候选资源的配置信息,确定所述时域资源指示信息在所述DCI对应的第一指示域,包括:
根据所述DCI是否为单载波或BWP的调度,按照预设策略选取所述第一指示域的大小。
所述预设策略包括:
若所述DCI为单载波或BWP的调度,则根据所调度的载波或BWP的配置信息,得到所述第一指示域的大小;
若所述DCI不是单载波或BWP的调度,则根据所述候选资源中多个载 波组或BWP组的配置信息,获得各个载波组或BWP组对应的第四指示域的大小,并将所有第四指示域中最大第四指示域的大小作为所述第一指示域的大小,或者,将所述多个载波组或BWP组中最大的单载波或者单BWP指示域的大小作为所述第一指示域的大小,或者,根据公式L’=S’ MAX*N得到所述第一指示域的大小L’,其中S’ MAX为所述多个载波组或BWP组中最大的单载波或BWP指示域的大小,N为所述候选资源中多个载波组或BWP组的最大载波或BWP数量;或者,根据所述候选资源中参考载波或BWP的配置信息,获得所述第一指示域的大小。
如此,对于DCI为单载波或BWP的调度,第一指示域的大小由所调度的载波或BWP的配置信息得到,如第一指示域的大小等于由配置信息得到的所调度的载波或BWP指示域的大小S single。对于DCI不是单载波或BWP的调度,由候选资源中多个载波组或BWP组的配置信息,获得各个载波组或BWP组对应的第四指示域的大小后,可将所有第四指示域中最大第四指示域的大小作为第一指示域的大小,或者,将多个载波组或BWP组中最大的单载波或BWP指示域的大小作为第一指示域的大小,或者,根据公式L’=S’ MAX*N得到第一指示域的大小L’,或者,根据候选资源中参考载波或BWP的配置信息,获得所述第一指示域的大小。
这里,对于DCI不是单载波或BWP的调度确定第一指示域的实现,类似于上述根据第三指示域的大小确定第一指示域的大小的实现,在此不再赘述。参考载波或BWP如上所述。
可选地,该实施例中,步骤102,包括:
若所述DCI调度参考载波或BWP,则所述调度时域资源为所述时域资源指示信息指示的时域资源;
若所述DCI调度非参考载波或BWP,则所述调度时域资源根据调度所述参考载波或BWP的时域位置确定。
这里,配置或预定义等方式设置了参考载波或BWP,通过参考载波或BWP的配置信息来得到第一指示域的大小。其中,参考载波或BWP可以是辅小区Pcell,cell ID最小或最大的cell或BWP,子载波间隔SCS最小或最大的cell或BWP。若DCI调度参考载波或BWP,则调度时域资源为该时域 资源指示信息指示的时域资源。若DCI调度非参考载波或BWP,则调度时域资源将根据调度参考载波或BWP的时域位置进一步确定,如与调度参考载波或BWP的时域位置重叠的第一个时隙slot、最后一个slot或所有slot。调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)时间位置为确定的slot或多个slot上对应的时隙内符号指示(Start and length indicator value,SLIV)的符号位置。这样,节省开销,并使得各小区分配的时域资源长度和位置一致。
可选地,该实施例中,所述时域资源指示信息包括:
第二标识,所述第二标识为时域资源的指示标识。
如此,当DCI的时域资源指示信息对于各载波或BWP进行共享时,可以配置多个时域资源的指示标识,通过具体的指示标识和/或偏移值来实现时域资源指示。
例如,可以配置多个Cell的时域资源指示信息的第二标识组合:若多个Cell为Cell 1和Cell 2,假设Cell 1和Cell 2分别配置了8个时域资源分配值,第二标识与Cell 1的时域资源分配值的指示索引标识Cell 1 Time Domain Resource Allocation(TDRA)index,以及Cell 2的时域资源分配值的指示索引标识对应Cell 1 TDRA index的对应如下表1所示:
表1
第二标识 Cell 1 TDRA index Cell 2 TDRA index
0 1 2
1 2 3
2 3 4
3 4 5
4 5 6
5 6 7
6 7 0
7 0 1
另外一种配置方式为,可以对该载波组或BWP组包含的载波或BWP分别配置新的TDRA表(区别于单独调度的TDRA表),组合起来为新的联合TDRA表。
可选的,该联合TDRA表特定时域资源分配的指示部分可被多个载波或 BWP共享,例如联合TDRA表配置cell 1的K0/K2,cell 2的K0/K2和共享的SLIV。
可选地,该实施例中,所述时域资源指示信息包括:第一指示信息和第二指示信息;
其中,所述第一指示信息为各载波或BWP的共享指示,所述第二指示信息为各载波或BWP的独立指示。
可选地,所述第一指示信息为时隙指示,所述第二指示信息为时隙内符号指示;或者,
所述第一指示信息为时隙内符号指示,所述第二指示信息为时隙指示。
如此,可增强一部分时域资源指示信息指示的灵活性,在时分复用(Time Division Duplex,TDD)场景下上行链路(Uplink,UL)和下行链路(Downlink,DL)配置不一样的小区下有用。
假设两个小区cell 1和cell 2,时隙指示(K0/K2)对于各载波或BWP进行独立指示,时隙内符号指示SLIV对于各载波或BWP共享指示,该时域资源指示信息所在域内,前S 1bit指示cell 1的K0/K2值,接着S 2bit指示cell 2的K0/K2值,最后S 3bit指示cell 1和cell 2的SLIV值。
此外,可选地,该实施例中,步骤102之后还包括:
若所述调度时域资源与对应的载波或BWP的上下行配置冲突,则确定所述调度时域资源无效。
这样,当DCI调度的载波组或BWP组配置的TDD上下行配置不同时,当DCI调度的时域资源在某一个或多个载波上与上下行配置不一致时,则该调度资源视为无效。例如,DCI调度上行传输,在载波2上指示的TDRA代表的资源部分符号配置为下行符号,则UE视为该调度无效,不发送任何数据。此时在载波1上指示的TDRA代表的资源不冲突,该上行PUSCH调度有效,UE发送数据。
综上,在获取到DCI的时域资源指示信息后,因该时域资源指示信息支持调度多个载波或BWP,则能够确定在多个载波或BWP上的调度时域资源,如此,可实现一个DCI调度多个载波或BWP,有效减少调度过程中PDCCH的开销。
如图2所示,本发明的实施例还提供了一种资源指示方法,应用于网络侧设备,包括:
步骤201,生成携带时域资源指示信息的下行控制信息DCI,所述时域资源指示信息支持调度多个载波或部分带宽BWP;
步骤202,发送DCI至用户侧设备。
按照步骤201和步骤202,应用本发明实施例方法的网络侧设备,生成携带时域资源指示信息的DCI,因该时域资源指示信息支持调度多个载波或BWP,将该DCI发送至用户侧设备,能够使得用户侧设备确定在多个载波或BWP上的调度时域资源,可实现一个DCI调度多个载波或BWP,有效减少调度过程中PDCCH的开销。
