具体实施方式
为使本公开要解决的技术问题、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。
针对MBS的传输,一般定义一个公共的频域资源,形成一个单独的BWP。
由于MBS的数据调度是针对小区内的所有终端或者针对一组终端发送,因此调度资源范围对于接收终端来说是相同的,即需要定义一个公共的频域资源,这个公共的频域资源形成一个MBS BWP,该频域资源的宽度(即包含的RB数)不超过终端的射频接收宽度。但是单独定义一个公共频域资源形成一个MBS的BWP,其问题如下:1)增加终端的实现复杂度,或者提升终端的成本。2)增加接收MBS或者单播的时延。而当前BWP的配置仅针对单播业务,或者仅针对广播组播业务,无法兼容单播业务和广播组播业务。

如图2所示,本公开实施例提供一种带宽部分BWP的配置方法,应用于网络侧设备,包括:
步骤201,为第一BWP配置第一专用参数、第二专用参数以及公共参数;其中,所述单播数据和所述广播组播数据共同使用所述公共参数;所述第一专用参数用于指示单播数据的传输;所述第二专用参数用于指示广播组播数据的传输。
本公开实施例中,第一BWP上既能够传输广播组播业务的PDSCH(Physical Downlink Shared Channel,物理下行共享信道)数据,也能够传输单播(unicast)的PDSCH数据。上述单播的数据泛指当前支持的除广播组播业务数据外的PDSCH数据。例如,单播数据为:
C-RNTI(小区无线网络临时标识)/CS-RNTI/MCS-RNTI/RA-RNTI/TC-RNTI对PDCCH加扰的基于终端的用户业务数据;
基于P-RNTI/SI-RNTI对PDCCH加扰的寻呼数据、系统消息数据。
作为一个可选实施例,所述第一BWP包括下述任意一个:
第一控制资源集(如,COREST#0,编号为0的控制资源集合)对应的BWP;
初始BWP;例如,基站通过广播消息定义的一个BWP,是终端在随机接入完成后用于替代CORESET#0的一个BWP;
通过高层信令配置的BWP,例如第一激活BWP,默认BWP等。终端连接态时,基站通过RRC配置多个BWP,对于主小区,第一激活BWP定义为RRC配置即为激活的BWP;对于副小区,第一激活BWP定义为随着小区激活某个BWP默认激活的BWP。当终端和基站间的激活BWP不匹配时(如基站发送了BWP切换命令,但终端没有收到),则终端和基站均切换到默认BWP上进行收发数据。
作为一个可选实施例,公共参数包括下述至少一项:
单播和广播组播共用的时域调度参数;
单播和广播组播共用的频域位置及带宽;
单播和广播组播共用的控制资源集参数;
第一BWP的标识;

作为另一个可选实施例,第一专用参数包括下述至少一项:
单播的时域调度参数;
单播的搜索空间参数;
单播的控制资源集参数;
单播的资源带宽和位置;
单播的资源标识。
作为另一个可选实施例,所述第二专用参数包括下述至少一项:
广播组播的专用参数配置标识;
广播组播的控制资源集参数;
广播组播的搜索空间参数;
广播组播的时域调度参数;
广播组播的公共资源带宽和位置;
广播组播的公共资源的标识。
在本公开的一些实施例中,在配置广播组播的搜索空间时,使用第二专用参数配置的广播组播的控制资源集合,和/或使用公共参数配置的控制资源集合。
在本公开的一些实施例中,在第二专用参数没有配置广播组播的控制资源集合时:配置广播组播的搜索空间时,只使用公共参数配置的控制资源集合。
在本公开的一些实施例中,所述广播组播的公共资源带宽和位置的配置,按照初始BWP公共参数中的位置和带宽的方法进行配置,其带宽大于或者小于初始BWP带宽。
本公开实施例提供第一专用参数、第二专用参数以及公共参数的两种配置方式。
其中,方式一为:在相关技术中的BWP框架中增加第二专用参数,即步骤201包括:
通过第一高层信令,配置所述第一BWP的第一专用参数;
通过第一广播消息或者第二高层信令,配置所述第一BWP的公共参数;
通过所述第一高层信令或者所述第一广播消息或者所述第二高层信令,配置所述第一BWP的第二专用参数。
该方式直接在相关技术中的BWP框架中增加第二专用参数,可以一步完成配置。当第一BWP是高层信令(例如第一高层信令或第二高层信令)配置给终端专用时,第二专用参数需要对每个终端发送一次。
其中,方式二为:单独配置第二专用参数,再将第二专用参数关联到第 一BWP上,即步骤201包括:
通过第三高层信令,配置所述第一BWP的第一专用参数;
通过第二广播消息或第四高层信令,配置所述第一BWP的公共参数;
通过第三广播消息或第五高层信令,配置所述第二专用参数,其中,所述第二专用参数与所述第一BWP关联;其中,所述第三广播消息与所述第二广播消息为不同的广播消息;所述第五高层信令与所述第三高层信令为不同的高层信令,所述第五高层信令与所述第四高层信令为不同的高层信令。
相应的,所述方法还包括:
通过高层信令或媒体接入控制层控制单元MAC CE发送关联消息;所述关联消息用于将所述第二专用参数和所述第一BWP关联;其中,所述关联消息包括:第一BWP的标识以及第二专用参数对应的配置标识。
或者,所述第二专用参数中包括所述第二专用参数对应的配置标识;所述第一BWP的配置参数中包括所述第二专用参数对应的配置标识;则携带相同第二专用参数对应的配置标识的第二专用参数和第一BWP为关联关系。
该方式中,由于广播组播的第二专用参数是多个终端公共内容,单播配置第二专用参数的可以通过广播消息一次发送,配置效率高。
可选地,上述第二专用参数对应的配置标识可以为:上述第二专用参数包括的广播组播的专用参数配置标识。
作为本公开的一个可选实施例,考虑到终端实现的成本,规定了在一个检测时长内(如1个时隙中),终端对候选PDCCH检测时,其PDCCH上的控制信令长度的不同个数有一定限制(如在一个小区里,基于C-RNTI配置的不同控制信令长度的数量不能超过3个,所有不同控制信令长度的数量不能超过4个)。本公开实施例还提供了不同控制信令长度的数量超过终端能力时的控制信令长度的缩减方法,即支持了网络侧设备的灵活调度,又能够保持当前物理下行控制信道PDCCH的检测能力。
其中,在控制信道的一个检测时长内,若单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和大于第一门限,控制信令长度(DCI size)缩减方法一:广播组播的控制信令长度和公共搜索空间的回退控制信令长度对齐。
在广播组播的控制信令长度和公共搜索空间的回退控制信令长度对齐的情况下,所述方法还包括:
利用所述回退控制信令的部分字段携带所述广播组播的频域调度信息的部分或全部信息。
其中,所述广播组播的频域调度信息长度大于所述回退控制信令中的频域调度信息长度。
其中,所述方法还包括:
利用所述回退控制命令中所述部分字段之外的其他字段对所述广播组播的频域调度信息指示范围进行扩展。
上述回退控制信令,是收基站发送的系统消息、寻呼消息等公共消息的调度信令,在5G系统可以指格式1_0(format 1_0)。
需要说明的是,上述缩减方法一,也可以不必门限作为条件,即无论是否大于门限,直接使用方法一,这样可以减少终端和基站的判断过程。
该缩减方式简化了控制信令长度对齐的过程,能够调度较大的广播组播频域带宽。
或者,在控制信道的一个检测时长内,若单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和大于第一门限,控制信令长度(DCI size)缩减方法二:对单播的控制信令长度的数量进行减少。
其中,对单播的控制信令长度进行减小的方式与相关技术相同。例如,单播的控制信令长度对应的DCI格式包括:format 0_0、format 1_0、format 0_0、format 1_0、format 0_2、format 1_2、format 0_1、format 1_1。通过调整终端专用搜索空间USS的频域分配指示比特数,使得公共搜索空间和终端专用搜索空间的频域调度指示的比特数相同,即format 0_0、format 1_0、format 0_0、format 1_0的DCI size相同。通过短长度的DCI补零的方式对齐长的DCI,使得format 0_2、format 1_2的DCI size相同。通过短长度的DCI补零的方式对齐长的DCI,使得format 0_1、format 1_1的DCI size相同。
若减少之后的单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和小于第一门限,则控制信令长度缩减完成。若减少之后的单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和 大于第一门限,所述方法还包括:
删除单播中的至少一个控制信令长度对应的DCI格式;例如,删除format 0_2/format 1_2的DCI size或者format0_1/format1_1的DCI size,保留广播组播的DCI size。(即不检测format 0_2/1_2或者format0_1/format1_1的PDCCH,检测MBS的PDCCH);
或者,
删除广播组播的控制信令长度对应的DCI格式,并利用单播的控制信道调度广播组播数据;对于终端来说,广播组播数据业务由组的G-RNTI调度机制,变为基于终端的C-RNTI调度;
或者,
从减少后的单播的控制信令长度中选择一个控制信令长度和广播组播的控制信令长度对齐;其中,选择的控制信令长度小于广播组播的控制信令长度。例如,选择和广播组播的控制信令长度最接近的单播控制信令格式,进行补零直到和广播组播的控制信令长度相同。若减少后的单播的控制信令长度均大于广播组播的控制信令长度,则使用删除单播中的至少一个控制信令长度对应的DCI格式或删除广播组播的控制信令长度对应的DCI格式的方式缩减控制信令长度的数量。
在一些实施例中,所述从减少后的单播的控制信令长度中选择一个控制信令长度和广播组播的控制信令长度对齐,包括:
选择和所述广播组播的控制信令长度最接近的单播控制信令格式,进行补零直到和所述广播组播的控制信令长度相同。
综上,本公开实施例中网络配置一个支持单播数据和广播组播数据传输的第一BWP,该第一BWP包含公共参数、单播数据专用的第一专用参数以及广播组播数据专用的第二专用参数,在不增加终端接收能力的基础上,使得终端能够接收MBS业务,提升了用户体验。进一步的本公开实施例还提供了不同控制信令长度的数量超过终端能力时的控制信令长度的缩减方法,即支持了网络侧设备的灵活调度,又能够保持当前物理下行控制信道PDCCH的检测能力。

通过第一高层信令,接收所述第一BWP的第一专用参数;
通过第一广播消息或者第二高层信令,接收所述第一BWP的公共参数;
通过所述第一高层信令或者所述第一广播消息或者所述第二高层信令,接收所述第一BWP的第二专用参数。
该方式直接在相关技术中的BWP框架中增加第二专用参数,可以一步完成配置。当第一BWP是高层信令(例如第一高层信令或第二高层信令)配置给终端专用时,第二专用参数需要对每个终端发送一次。
其中,方式二为:单独配置第二专用参数,再将第二专用参数关联到第一BWP上,即步骤301包括:
通过第三高层信令,接收所述第一BWP的第一专用参数;
通过第二广播消息或第四高层信令,接收所述第一BWP的公共参数;
通过第三广播消息或第五高层信令,接收所述第二专用参数,其中,所述第二专用参数与所述第一BWP关联;其中,所述第三广播消息与所述第二广播消息为不同的广播消息;所述第五高层信令与所述第三高层信令为不同的高层信令,所述第五高层信令与所述第四高层信令为不同的高层信令。
相应的,所述方法还包括:
通过高层信令或媒体接入控制层控制单元MAC CE接收关联消息;所述关联消息用于将所述第二专用参数和所述第一BWP关联;其中,所述关联消息包括:第一BWP的标识以及第二专用参数对应的配置标识。
或者,所述第二专用参数中包括所述第二专用参数对应的配置标识;所述第一BWP的配置参数中包括所述第二专用参数对应的配置标识;则携带相同第二专用参数对应的配置标识的第二专用参数和第一BWP为关联关系。
该方式中,由于广播组播的第二专用参数是多个终端公共内容,单播配置第二专用参数的可以通过广播消息一次发送,配置效率高。
作为本公开的一个可选实施例,考虑到终端实现的成本,规定了在一个检测时长内(如1个时隙中),终端对候选PDCCH检测时,其PDCCH上的控制信令长度的不同个数有一定限制(如在一个小区里,基于C-RNTI配置的不同控制信令长度的数量不能超过3个,所有不同控制信令长度的数量不能超过4个)。本公开实施例还提供了不同控制信令长度的数量超过终端能力时的控制信令长度的缩减方法,即支持了网络侧设备的灵活调度,又能够保持当前物理下行控制信道PDCCH的检测能力。
其中,在控制信道的一个检测时长内,若单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和大于第一门限,控制信令长度 (DCI size)缩减方法一:
广播组播的控制信令长度和公共搜索空间的回退控制信令长度对齐。
在广播组播的控制信令长度和公共搜索空间的回退控制信令长度对齐的情况下,所述方法还包括:
利用所述回退控制信令的部分字段携带所述广播组播的频域调度信息的部分或全部信息。
在本公开的一些实施例中,所述广播组播的频域调度信息长度大于所述回退控制信令中的频域调度信息长度。
在本公开的一些实施例中,利用所述回退控制命令中所述部分字段之外的其他字段对所述广播组播的频域调度信息指示范围进行扩展。
上述回退控制信令,是收基站发送的系统消息、寻呼消息等公共消息的调度信令,在5G系统可以指格式1_0(format 1_0)。
需要说明的是,上述缩减方法一,也可以不必门限作为条件,即无论是否大于门限,直接使用方法一,这样可以减少终端和基站的判断过程。
该缩减方式简化了控制信令长度对齐的过程,能够调度较大的广播组播频域带宽。
或者,在控制信道的一个检测时长内,若单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和大于第一门限,控制信令长度(DCI size)缩减方法二:对单播的控制信令长度的数量进行减少。
其中,对单播的控制信令长度进行减小的方式与相关技术相同。例如,单播的控制信令长度对应的DCI格式包括:format 0_0、format 1_0、format 0_0、format 1_0、format 0_2、format 1_2、format 0_1、format 1_1。通过调整终端专用搜索空间USS的频域分配指示比特数,使得公共搜索空间和终端专用搜索空间的频域调度指示的比特数相同,即format 0_0、format 1_0、format 0_0、format 1_0的DCI size相同。通过短长度的DCI补零的方式对齐长的DCI,使得format 0_2、format 1_2的DCI size相同。通过短长度的DCI补零的方式对齐长的DCI,使得format 0_1、format 1_1的DCI size相同。
若减少之后的单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和小于第一门限,则控制信令长度缩减完成。若减少之后的 单播的不同控制信令长度的数量和广播组播的不同控制信令长度的数量之和大于第一门限,所述方法还包括:
删除单播中的至少一个控制信令长度对应的DCI格式;例如,删除format 0_2/format 1_2的DCI size或者format0_1/format1_1的DCI size,保留广播组播的DCI size。(即不检测format 0_2/1_2或者format0_1/format1_1的PDCCH,检测MBS的PDCCH);
或者,
删除广播组播的控制信令长度对应的DCI格式,并利用单播的控制信道调度广播组播数据;对于终端来说,广播组播数据业务由组的G-RNTI调度机制,变为基于终端的C-RNTI调度;
或者,
从减少后的单播的控制信令长度中选择一个控制信令长度和广播组播的控制信令长度对齐;其中,选择的控制信令长度小于广播组播的控制信令长度。例如,选择和广播组播的控制信令长度最接近的单播控制信令格式,进行补零直到和广播组播的控制信令长度相同。若减少后的单播的控制信令长度均大于广播组播的控制信令长度,则使用删除单播中的至少一个控制信令长度对应的DCI格式或删除广播组播的控制信令长度对应的DCI格式的方式缩减控制信令长度的数量。
承接上例,控制信令长度缩减完成后,所述方法还包括:
终端检测PDCCH,根据下行控制信息DCI指示接收广播组播数据或者单播数据。
例如,终端在需要检测的候选PDCCH上,根据DCI格式类型和DCI size的长度,继续PDCCH盲检和DCI内容解析,并根据解析结果接收PDSCH,反馈HARQ-ACK。特别的,在终端侧,因为接收广播组播和单播的PDSCH需要使用不同的配置参数,在终端执行时需要一定的时间,这会影响到HARQ-ACK的反馈时间,如:当配置PDSCH的参数为1个符号时,需要将HARQ-ACK的最小反馈时延向后延迟1个符号。特别是在PDCCH和PDSCH在一个时隙中时。
综上,本公开实施例中网络配置一个支持单播数据和广播组播数据传输 的第一BWP,该第一BWP包含公共参数、单播数据专用的第一专用参数以及广播组播数据专用的第二专用参数,在不增加终端接收能力的基础上,使得终端能够接收MBS业务,提升了用户体验。进一步的本公开实施例还提供了不同控制信令长度的数量超过终端能力时的控制信令长度的缩减方法,即支持了网络侧设备的灵活调度,又能够保持当前物理下行控制信道PDCCH的检测能力。
为了更清楚的描述本公开实施例提供的BWP的配置方法,下面结合几个示例进行详细描述。
示例一,第一BWP为初始BWP
步骤一,配置第一BWP的第一专用参数、第二专用参数以及公共参数。
A1:在广播消息中,配置初始BWP的公共参数。
初始BWP的公共参数的配置,通过广播信道在小区中广播公共参数,对于MBS业务感兴趣的终端,进行相关配置参数的解析。公共参数包括下述至少一项:
BWP ID:标识配置的BWP识别号,初始BWP的编号为基站的默认编号,如ID=0;
子载波间隔SCS:数值为15KHz,30KHz,60KHz,120KHz,240KHz,480KHz,960KHz中的一个;
CP(Cyclic Prefix,循环前缀)类型:设置为扩展CP或者正常CP;
BWP的宽度和位置指示(locationAndBandwidth):该参数包括起始位置RB start和长度
Figure PCTCN2021120195-appb-000001
(RB个数);locationAndBandwidth最大数值,按照每次载波最大支持的RB数计算的(如:载波最多支持275RB)即RB start和长度
Figure PCTCN2021120195-appb-000002
的组合种类数为275*(275+1)/2=37950,locationAndBandwidth的取值范围为(0..37949);表示该数值信息位数为16bit。如:配置初始BWP的起始RB位置RB start=50,初始BWP频域宽度
Figure PCTCN2021120195-appb-000003
控制资源集:用于指示单播和广播组播的控制信道的资源集合,包括PDCCH的占用的符号个数(1,2或者3个),频域带宽,控制资源ID(识别号)等。
A2:在广播消息或高层信令(如RRC消息)中,配置MBS专用的第二 专用参数;
MBS的专用参数配置,通过广播信道在小区中广播,对于MBS业务感兴趣的终端,进行相关配置参数的解析,主要包括下述至少一项:
控制资源集:用于指示MBS的控制信道的资源集合,包括PDCCH的占用的符合个数,频域带宽,控制资源ID(识别号)等;该字段可选配内容(基站可能配置,也可能不配置)。
搜索空间:用于指示MBS的控制信道检测时机,指示终端在哪些时间上进行MBS PDCCH的检测,其PDCCH的资源集合大小由控制资源ID(识别号)指示,当基站没有配置专门用于MBS的控制资源集时,则使用BWP公共参数中配置的控制信道资源集。
时域调度参数:时域调度参数以参数用于PDSCH的数据调度,表示调度的PDSCH的时域上的时域位置,包括:起始位置和长度。这里的起始位置包括从接收到PDCCH后的时隙起始位置(k0),符号起始位置(S)和数据长度(L)。
MBS公共资源带宽和位置:该参数的用于MBS调度的最大带宽。其定义方法可以使用如下的一种:
方法1:按照配置初始BWP公共参数中的locationAndBandwidth的方法进行配置,即:按照最大275RB计算。RB start和长度
Figure PCTCN2021120195-appb-000004
的组合种类数为:275*(275+1)/2=37950;即locationAndBandwidth的范围为(0..37949)。使用长度为16比特的参数表示。该方法的好处是MBS的公共频域资源的配置参数灵活,可以大于、小于初始BWP带宽的数值。
方法2:按照初始BWP配置的带宽为最大数值,进行频域范围的指示。如:假设在上一步配置的初始BWP带宽为如配置初始BWP的起始RB位置RB start=50,初始BWP频域宽度
Figure PCTCN2021120195-appb-000005
则配置MBS的公共频域带宽的RB start和长度
Figure PCTCN2021120195-appb-000006
的组合种类数为:100*(100+1)/2=5050;即使用长度13比特的位数表示,通过该数值计算出来RB start是相对于初始BWP带宽起始位置的偏移量,
Figure PCTCN2021120195-appb-000007
为频域宽度。该方法能够节省信息开销。
A3:通过高层信令(如RRC消息),配置单播专用的第一专用参数。
单播的专用参数配置,通过RRC消息进行相关配置参数的解析,主要包 括下述至少一项:
控制资源集:用于指示单播的控制信道的资源集合,包括PDCCH的占用的符合个数,频域带宽,控制资源ID(识别号)等。
搜索空间:用于指示单播的控制信道检测机会,指示终端在哪些时间上进行单播PDCCH的检测,其PDCCH的资源集合大小由控制资源ID(识别号)指示。
时域调度参数:时域调度参数以参数用于PDSCH的数据调度,表示调度的PDSCH的时域上的时域位置,包括:起始位置和长度。这里的起始位置包括从接收到PDCCH后的时隙起始位置(k0),符号起始位置(S)和数据长度(L)。
上述A1/A2可通过如下消息实施:
下行公共配置消息,在广播信道上发送给终端,包含至少如下两个消息:
配置初始BWP的公共参数消息(initialDownlinkBWP);
配置MBS的专用参数消息(BWP-DownlinkDedicated)。其中,在配置MBS的专用参数消息包含如下消息:
MBS的公共频域资源参数(locationAndBandwidth,数值范围为(0..37949),或者(0…
Figure PCTCN2021120195-appb-000008
),上述
Figure PCTCN2021120195-appb-000009
是指初始BWP带宽;
配置MBS的PDCCH控制信道参数;
配置MBS的PDSCH数据信道参数。
例如,假设初始BWP带宽配置参数为:RB start=50,
Figure PCTCN2021120195-appb-000010
MBS的带宽配置参数为:RB mbs_start=10,
Figure PCTCN2021120195-appb-000011
则MBS的频域位置和初始BWP的频域位置关系如图4所示。
需要说明的是,该示例基于在初始BWP上配置MBS的专用参数,由于初始BWP的公共参数是通过广播消息发送的,因此该示例按照广播消息发送来实现。MBS的专用参数在终端特定的BWP上配置时,MBS的专用参数是需要通过RRC消息配置。
步骤二,控制信令长度(DCI size)的数量的缩减。缩减控制信令长度的数量的方式包括:
先减小单播的DCI size的数量,如果减少后的“单播的不同DCI-size”的个数,与“MBS的不同DCI size”个数之和,满足终端DCI检测能力的要求,则执行步骤三;否则去掉单播中的一个DCI size(如:去掉format 0_2和format 1_2的DCI size,或者format 0_1或者1_1),终端也不对相应DCI size的DCI格式进行检测,终端执行MBS相关的DCI格式检测。
假设第一BWP的不同DCI size的个数为7个,如表1所示。
不同DCI长度个数 包括(DCI格式) 所在搜索空间
DCI-SIZE-1 format 0_0,format 1_0 公共搜索空间CSS
DCI-SIZE-2 format 0_0,format 1_0 UE搜索空间USS,
DCI-SIZE-3 format 0_2 UE搜索空间USS
DCI-SIZE-4 format 1_2 UE搜索空间USS
DCI-SIZE-5 format 0_1 UE搜索空间USS
DCI-SIZE-6 format 1_1 UE搜索空间USS
DCI-SIZE-7 Format x 用于MBS控制信道检测
表1
如表1所示,将DCI-SIZE-1和DCI-SIZE-2的长度对齐,统一到一个DCI-SIZE-A上;将DCI-SIZE-3和DCI-SIZE-4的长度对齐,统一到一个DCI-SIZE-B上;将DCI-SIZE-5和DCI-SIZE-6的长度对齐,统一到一个DCI-SIZE-C上。
经过上述步骤后,如果不同DCI size的个数仍然超过终端的信道检测能力。则:基站和终端均删除掉一个上述单播的DCI size所对应的所有DCI格式,即终端不在这些删除掉的DCI格式上做PDCCH检测。并检测MBS对应的DCI格式和其它未删除掉单播的DCI格式。例如:当删除掉DCI-SIZE-C对应的format 0_1,format 1_1时,则终端仅仅执行:format 0_0,format 1_0,format 0_2,format 1_2,Format x的检测。
步骤三,终端检测PDCCH,根据DCI指示接收MSB数据和/或单播数据。
终端在需要检测的候选PDCCH上,根据DCI格式类型和DCI size的长度,继续PDCCH盲检和DCI内容解析,并根据解析结果接收PDSCH,反馈HARQ-ACK。
特别的:在终端侧,因为接收MBS和单播的PDSCH需要使用不同的配置参数,而参数的重新配置是终端检测到PDCCH,且做完DCI解析后,才能够确定使用MBS或者单播的PDSCH的参数,在终端执行时需要一定的时间,这会影响到HARQ-ACK最小的反馈时间(即影响N1数值:从PDSCH结束到HARQ-ACK反馈的最早时间),如:当配置单播或者MBS的PDSCH参数时,增加一个N1_offset(如:N1_offset=2符号),则基站指示HARQ-ACK反馈的时间不小于(N1+N1_offset);这里的N1为没有引入MBS数据调度时的HARQ-ACK反馈最小数值。
需要说明的是,本示例的步骤一是将初始BWP配置为第一BWP,同时也可以使用高层消息配置的其它BWP作为第一BWP,如使用如下消息将非初始BWP配置为第一BWP,BWP配置消息中包含如下参数信息:
BWP Id:标识本次配置的第一BWP识别号;
BWP公共参数:标识本次配置的BWP的公共参数;
BWP-Dedicated:标识本次配置的BWP的单播的专用参数;
BWP-Dedicated-MBS:标识第一BWP中,MBS的专用参数。
示例二
步骤一,配置第一BWP的第一专用参数、第二专用参数以及公共参数。
B1:通过高层信令(如RRC消息)配置某个特定BWP的公共参数。
配置某特定BWP的公共参数,通过高层消息发送;当配置的是初始BWP时,公共参数通过广播信道发送,当配置的BWP是针对特定终端时,使用RRC消息配置,下面以针对特定终端的BWP为例。主要参数包括下述至少一项:
BWP ID:标识配置的BWP识别号,数值为1或者4;
子载波间隔SCS:数值为15KHz,30KHz,60KHz,120KHz,240KHz,480KHz,960KHz中的一个;
CP(Cyclic Prefix,循环前缀)类型:设置为扩展CP或者正常CP;
BWP的宽度和位置指示(locationAndBandwidth):该参数包括起始位置RB start和长度
Figure PCTCN2021120195-appb-000012
(RB个数);locationAndBandwidth最大数值,按照每次载波最大支持的RB数计算的(如:载波最多支持275RB)即RB start和长度
Figure PCTCN2021120195-appb-000013
的组合种类数为275*(275+1)/2=37950,locationAndBandwidth的取值范围为(0..37949);表示该数值信息位数为16bit。
控制资源集:用于指示单播和广播组播的控制信道的资源集合,包括PDCCH的占用的符号个数(1,2或者3个),频域带宽,控制资源ID(识别号)等。
B2:在广播组播或专用消息中,配置MBS的第二专用参数;
MBS的专用参数配置,通过广播信道在小区中广播,对于MBS业务感兴趣的终端,进行相关配置参数的解析,主要包括下述至少一项:
控制资源集:用于指示MBS的控制信道的资源集合,包括PDCCH的占用的符合个数,频域带宽,控制资源ID(识别号)等;该字段可选配内容(基站可能配置,也可能不配置)。
搜索空间:用于指示MBS的控制信道检测时机,指示终端在哪些时间上进行MBS PDCCH的检测,其PDCCH的资源集合大小由控制资源ID(识别号)指示,当基站没有配置专门用于MBS的控制资源集时,则使用BWP公共参数中配置的控制信道资源集。
时域调度参数:时域调度参数以参数用于PDSCH的数据调度,表示调度的PDSCH的时域上的时域位置,包括:起始位置和长度。这里的起始位置包括从接收到PDCCH后的时隙起始位置(k0),符号起始位置(S)和数据长度(L)。
MBS公共资源带宽和位置:该参数的用于MBS调度的最大带宽。其定义方法如下:
定义一个频域的绝对位置(如位置点A);通过定义MBS公共资源的绝对位置,可让所有接收终端,根据该数值能够确定该频率的位置,如可以使用绝对无线频道编号(Absolute Radio Frequency Channel Number-ARFCN),该数值是全球统一的无线频道编号。
基于位置点A,使用位置和带宽参数,确定MBS公共资源的起始和带宽。例如,使用位置和带宽参数指示给终端,该参数包括RB start和长度
Figure PCTCN2021120195-appb-000014
该RB start可以表示为相对于位置点A的偏移量。
Figure PCTCN2021120195-appb-000015
表示MBS公共资源的带宽。
MBS公共资源ID:标识本次配置的ID号,用于MBS的专用参数和相应的BWP建立关系。如果基站只支持一个MBS的专用BWP的参数配置,则该ID可默认为为0,或者不配置。
B3:基站指示将MBS的第二专用参数关联到某一特定的BWP上。关联方法可以使用RRC消息指示,也可以使用MAC CE指示,在关联消息中,至少包括BWP ID和MBS公共资源ID。使用如下几种关联消息的一种:
1)BWP配置消息中,包含如下参数信息,进行BWP ID和MBMS公共资源ID进行关联:
BWP-Id:标识本次配置的第一BWP识别号。
BWP-DownlinkCommon:标识本次配置的BWP的公共参数。
MBS公共资源ID.:标识本次配置的第一BWP中关联的MBS公共资源配置索引号。
2)在MAC CE或者RRC中,使用关联命令进行BWP ID和MBS公共资源ID进行关联,关联命令包括:
BWP-Id:标识本次配置的混合BWP识别号。
载波ID:小区载波编号。
MBS公共资源ID.:标识本次配置的第一BWP中关联的MBS公共资源配置索引号。
步骤二:控制信令长度(DCI size)的数量的缩减。缩减控制信令长度的数量的方式包括:
先减小单播的DCI size的数量,如果减少后的“单播的不同DCI-size”的个数,与“MBS的不同DCI size”个数之和,满足终端DCI检测能力的要求,则执行步骤三;否则去掉MBS的DCI size,使用单播的PDCCH调度MBS数据。(对于该终端来讲,MBS数据业务由组的G-RNTI调度机制,变为基于终端的C-RNTI调度)。
假设第一BWP的不同DCI size的个数为7个,如表2所示。
不同DCI长度个数 包括(DCI格式) 所在搜索空间
DCI-SIZE-1 format 0_0,format 1_0 公共搜索空间CSS
DCI-SIZE-2 format 0_0,format 1_0 UE搜索空间USS,
DCI-SIZE-3 format 0_2 UE搜索空间USS
DCI-SIZE-4 format 1_2 UE搜索空间USS
DCI-SIZE-5 format 0_1 UE搜索空间USS
DCI-SIZE-6 format 1_1 UE搜索空间USS
DCI-SIZE-7 Format x 用于MBS控制信道检测
表2
如表2所示,将DCI-SIZE-1和DCI-SIZE-2的长度对齐,统一到一个DCI-SIZE-A上;将DCI-SIZE-3和DCI-SIZE-4的长度对齐,统一到一个DCI-SIZE-B上;将DCI-SIZE-5和DCI-SIZE-6的长度对齐,统一到一个DCI-SIZE-C上。
经过上述步骤后,如果不同DCI的个数仍然超过终端的信道检测能力。则基站和终端均删除掉一个上述MBS的DCI size所对应的所有DCI格式,即终端不在这些删除掉的MBS DCI格式上做PDCCH检测。MBS的检测使用单播的DCI format检测,使用单播的格式可以是下行调度的格式的一个或者多个(format 1_0/1_1/1_2)。
步骤三,终端检测PDCCH,根据DCI指示接收MSB数据和/或单播数据。
终端在需要检测的候选PDCCH上,根据DCI格式类型和DCI size的长度,继续PDCCH盲检和DCI内容解析,并根据解析结果接收PDSCH,反馈HARQ-ACK。
特别的:在终端侧,因为接收MBS和单播的PDSCH需要使用不同的配置参数,而参数的重新配置是终端检测到PDCCH,且做完DCI解析后,才能够确定使用MBS或者单播的PDSCH的参数,在终端执行时需要一定的时间,这会影响到HARQ-ACK最小的反馈时间(即影响N1数值:从PDSCH结束到HARQ-ACK反馈的最早时间),如:当配置单播或者MBS的PDSCH参数时,增加一个N1_offset(如:N1_offset=2符号),则基站指示HARQ-ACK反馈的时间不小于(N1+N1_offset);这里的N1为没有引入MBS数据调度时的HARQ-ACK反馈最小数值。
示例三,单播DCI size和MBS DCI size对齐
对单播的控制信令长度的数量进行减少,得到的DCI size的长度如表3 所示。
Figure PCTCN2021120195-appb-000016
表3
假设终端的最多支持不同DCI size的个数为3个,使用下面之一的方法,将上述4个不同的DCI size减少到3个。
从生成的“单播的DCI size”(三个size:A/B/C),选择其中一个和MBS的DCI size对齐。方法是:判断USS的DCI size是否有小于MBS DCI size,
如果有,选择和MBS DCI size最相近的DCI格式,进行补零,直到和MBS DCI size相同
如果没有(MBS DCI size小于所有上述3个size),则:
删除MBS的DCI size对应的DCIT格式,MBS的检测使用单播的DCI format检测,使用单播的格式可以是下行调度的格式的一个或者多个(format 1_0/1_1/1_2)。
示例四,单播DCI size和MBS DCI size对齐
本公开实施例中,DCI size的长度如表1或表2所示。本示例中将MBS的DCI格式Format x的长度DCI-SIZE-7和回退DCI的格式(format 0_0,format 1_0)的长度DCI-SIZE-1对齐,即使DCI-SIZE-7等于DCI-SIZE-1,这样就可以使用相关技术中的DCI size的对齐方案,确保不同的DCI size的个数在终端的能力之内。
例如,MBS的DCI格式,以format 1_0(格式1_0)为基础,使用格式1_0中的一些字段信息,表示MBS的调度信息中的一部分信息。
1)格式1_0的字段1(DCI格式指示)在回退DCI中指示上/下行调度,在MBS调度中,由于只有下行数据调度,因此该字段对于MBS可以使用在其他方面的指示信息,如这里使用该比特指示“时域资源分配指示”的一部 分信息。
2)“PUCCH功率控制参数”字段指示特定终端的上行PUCCH功率控制命令,在MBS调度中,由于调度的是针对一个群组终端,该字段段对于MBS可以使用在其他方面的指示信息,如这里使用该比特指示“时域资源分配指示”的一部分信息。
3)格式1_0的字段2(频域资源分配指示),使用字段1(DCI格式指示,1比特),字段11(PUCCH资源指示,2bit)为例,来说明频域分配指示超过48RB的情况。如表4所示。
Figure PCTCN2021120195-appb-000017
表4
当MBS的公共资源带宽小于等于48RB时,仅仅使用低比特的11位表示MBS的频域调度信息。
当MBS的公共资源带宽小于等于90RB时,中比特(1比特)和低比特(11比特)位表示MBS的频域调度信息。
当MBS的公共资源带宽小于等于180RB时,高比特(2比特),中比特(1比特)和低比特(11比特)位表示MBS的频域调度信息。
