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。
本发明实施例的资源确定方法应用于用户侧设备,用户侧设备(user equipment,UE)可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备。
应该知道的是,本发明实施例中,多个载波或带宽部分(Bandwidth Part,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的频域资源指示信息,所述频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的频域资源指示信息支持调度多个载波或BWP,且能够调度单载波或BWP。因此,通过该步骤,获取到DCI的频域资源指示信息,了解到网络侧设备的调度,进而执行下一步。
步骤102,根据所述频域资源指示信息,确定多个载波或BWP上的调度频域资源。
本步骤中,在步骤101获取到的支持调度多个载波或BWP的频域资源指示信息后,根据该频域资源指示信息,确定对应该频域资源指示信息在多个载波或BWP上的调度频域资源。
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的频域资源指示信息后,因该频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上的调度频域资源,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频域资源指示信息的DCI并发送,因该频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,就能够获取到该频域资源指示信息,从而确定多个载波或BWP上的调度频域资源。
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,确定所述频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,得到所述频域资源指示信息。
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频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频域资源指示信息。
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频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ID,或者,载波指示符CIF,或者,BWP ID。在按照第一标识顺序进行排序时,可由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频域资源分配预设位置,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的频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的频域资源指示仅需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的频域资源指示。
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 所述频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;
根据所述第二指示域的大小,确定所述第一指示域的大小。
可选地,所述根据所述第二指示域,确定所述第一指示域的大小,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的频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对应的频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(频域分配相关域)的大小,后S 2个bit为Cell 2对应的子域的大小。
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的频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频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Cell2,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对应的子域为其频域资源指示分配为高(或低)S 1bit,Cell 2对应的子域为其频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对应的子域为其频域资源指示分配为高S 1bit,Cell 2对应的子域为其频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的频域资源指示;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的频域资源指示。当然,第一指示域 中各载波或BWP对应的子域为各自的频域资源指示的分配可均为高位或者均为低位。
具体的,对于调度下行数据的DCI,第一指示域包括频域资源分配(Frequency domain resource allocation,FDRA)域和/或虚拟资源块(Virtual Resource block,VRB)to物理资源块(Physical Resource block,PRB)指示域。对于调度上行数据的DCI,第一指示域包括FDRA域和/或跳频指示域。
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,确定所述频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,若第一指示域在排序后具有剩余比特,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频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Cell3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Cell2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5bit为无效比特,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所需的频域资源分配相关域(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频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频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Cell 2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频域资源指示的大小。
例如,DCI可调度载波组1(包括Cell 1和Cell 2)和载波组2(包括Cell3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的频域资源指示,后10bit中仅使用高3bit或者低3bit进行Cell 2的频域资源指示;另一方面,DCI的第一指示域的20bit中,可使用连续的bit进行小区的频域资源指示,各小区对应的子域直接对小区的频域资源指示,则20bit中前2bit为Cell 1对应的子域,直接进行Cell 2的频域资源指示,之后的3bit为Cell 2对应的子域,进行Cell 2的频域资源指示,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,确定所述频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。
可选地,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。
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’。
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。
另外,考虑到若第一指示域过大,DCI传输会消耗更多资源。所以,可选地,该实施例中,网络侧设备会对频域资源指示信息进行缩减,相对的,所述根据所述第一指示域,得到所述频域资源指示信息,包括:
按照第一阈值对所述第一指示域进行缩减,得到第五指示域;
在所述第五指示域中获得所述频域资源指示信息。
这里,第一阈值通过配置(如高层信令配置)或者预定义等方式获取。用户侧设备按照该第一阈值(如1/2)对第一指示域进行缩减得到第五指示域,则在第五指示域中可获得该频域资源指示信息。
可选地,所述调度频域资源的分配的粒度对应所述第一阈值进行加倍。
即,第一指示域的缩减,是通过对调度频域资源的分配的粒度进行加倍,而加倍的实现对应该第一阈值,以该第一阈值的倒数加倍。当然,调度频域资源的分配的粒度进行加倍,可以采用第二阈值,该第二阈值是第一阈值的倒数。例如,对于Type 0(非连续频域资源分配)频域资源分配方式,资源块组的大小RBG size按照RRC配置的粒度加倍(如2倍),从而使得所需位图bitmap数目变为1/2;对于Type 1(连续频域资源分配)频域资源分配方式,每多个(如2个)连续的RB看作一个虚拟的RB进行资源分配,这样所需频域分配比特数目缩减为1/2。可选的,对于交织方式指示或者跳频指示,可以默认不支持交织方式或者跳频方式,也就是当DCI调度数目大于1的多 载波或BWP时,无交织方式或者跳频方式指示。
可选地,该实施例中,所述频域资源指示信息包括:
第二标识和/或偏移值,所述第二标识为频域资源的指示标识。
如此,当DCI的频域资源指示信息对于各载波或BWP进行共享时,可以配置多个频域资源的指示标识,通过具体的指示标识和/或偏移值来实现频域资源指示。
例如,可以配置多个Cell的频域资源指示信息的第二标识组合:若多个Cell为Cell 1和Cell 2,当Cell 1和Cell 2上的激活BWP都配置为Type 1资源分配,并且Cell 1上需要3bit指示其RIV(即频域的PRB组合),Cell 2上需要2bit指示其RIV,则DCI的频域资源指示信息所在的域为3bit。频域资源的指示标识对应Cell 1 RIV和Cell 2 RIV如下表1所示:
表1
第二标识 Cell 1 RIV Cell 2 RIV
0 0 0
1 1 1
2 2 2
3 3 3
4 4 0
5 5 1
6 6 2
7 7 3
当然,在DCI的频域资源指示信息所在的域中,可使用低位2bit来指示Cell 2的频域资源分配。
为了基站配置的组合更加灵活,基站可以显示配置上表指示的组合(此时该域大小可取决于配置组合的数目)或者配置偏移值,如下表2所示:
表2
第二标识 Cell 1 RIV Cell 2 RIV
0 (0+offset1)mod 8 (0+offset2)mod 4
1 (1+offset1)mod 8 (1+offset2)mod 4
2 (2+offset1)mod 8 (2+offset2)mod 4
3 (3+offset1)mod 8 (3+offset2)mod 4
4 (4+offset1)mod 8 (0+offset2)mod 4
5 (5+offset1)mod 8 (1+offset2)mod 4
6 (6+offset1)mod 8 (2+offset2)mod 4
7 (7+offset1)mod 8 (3+offset2)mod 4
其中,offset1和offset2可以只配置一个,如果没配置则默认为0。如,配置offset1,而offset2默认为0。
此外,可选地,在该实施例中,所述用户侧设备不期望以下至少一项:
所述候选资源的各个载波或BWP有不同的子载波间隔(subcarrier spacing,SCS);
所述候选资源的各个载波或BWP有不同的频域分配方式;

所述候选资源的各个载波或BWP有不同的虚拟资源块VRB到PRB图谱配置;
DCI调度的候选资源的各个载波或BWP有不同的跳频模式配置。
综上,在获取到DCI的频域资源指示信息后,因该频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上的调度频域资源,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。

存储器509可用于存储软件程序以及各种数据。存储器509可主要包括存储程序区和存储数据区,其中,存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等;存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外,存储器509可以包括高速随机存取存储器,还可以包括非易失性存储器,例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器510是用户侧设备的控制中心,利用各种接口和线路连接整个用户侧设备的各个部分,通过运行或执行存储在存储器509内的软件程序和/或模块,以及调用存储在存储器509内的数据,执行用户侧设备的各种功能和处理数据,从而对用户侧设备进行整体监控。处理器510可包括一个或多个 处理单元;优选的,处理器510可集成应用处理器和调制解调处理器,其中,应用处理器主要处理操作系统、用户界面和应用程序等,调制解调处理器主要处理无线通信。可以理解的是,上述调制解调处理器也可以不集成到处理器510中。
用户侧设备500还可以包括给各个部件供电的电源511(比如电池),优选的,电源511可以通过电源管理系统与处理器510逻辑相连,从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外,用户侧设备500包括一些未示出的功能模块,在此不再赘述。
优选的,本发明实施例还提供一种通信设备,包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序,所述计算机程序被所述处理器执行时实现如上所述的资源确定方法,或者,如上所述的资源指示方法实施例的各个过程,且能达到相同的技术效果,为避免重复,这里不再赘述。
