Description

准共址参考信号确定方法、装置、网络设备和存储介质 技术领域
本公开涉及但不限于通信技术领域。
背景技术
5G(5th Generation Mobile Networks，第五代移动通信技术)NR(New Radio，新空口)技术中，当采用射频波束的时候，PDSCH(Physical Downlink Shared Channel，物理下行共享信道)/AP-CSI-RS(Aperiodic-Channel State Information-Reference Signal，非周期信道状态信息测量参考信号)的波束可以通过DCI(Downlink Control Information，下行控制信息)动态通知，但是由于在缓存PDSCH/AP-CSI-RS的时候，DCI还没有成功解码出来，或者即使成功解码出来，DCI中指示的波束，终端还来不及打出。为此需要考虑DCI和AP-CSI-RS的时间间隔小于预定值时的PDSCH/AP-CSI-RS的默认波束问题。
5G中采用包括控制信道资源集合CORESET的slot(时隙)集合中距离PDSCH/AP-CSI-RS最近slot中的最低CORESET的波束作为PDSCH/AP-CSI-RS的波束。
由于一个BWP(Bandwidth Part，部分带宽)中最多可以配置3个CORESET，PDSCH/AP-CSI-RS的默认波束比较受限。一方面一个slot中PDSCH/AP-CSI-RS的默认波束只有一个，PDSCH/AP-CSI-RS的默认波束的灵活性较差，因此如何提高PDSCH/AP-CSI-RS的默认波束的灵活度成为亟需解决的主要问题。另一方面当采用多TRP(Transmission Reference Point，传输参考点)发送的时候，PDCCH(Physical Downlink Control Channel，物理下行控制信道)的波束个数和PDSCH的波束个数不对等时， 如何确定DSCH/AP-CSI-RS的默认波束也是亟需解决的问题。
发明内容
本公开实施例提供的准共址参考信号确定方法、装置、网络设备和存储介质，旨在解决如何改善相关技术中PDSCH/AP-CSI-RS的默认波束的灵活性较差，以及PDCCH的波束个数和PDSCH的波束个数不对等时，如何确定DSCH/AP-CSI-RS的默认波束的问题。

根据本公开提供的实施例，第一预定特征的控制信道元素包括如下至少之一：所述控制信道元素属于的控制信道元素组与所述数据信道和/或信号之间存在对应关系；所述控制信道元素所在的频域带宽索引与所述数据信道和/或信号所在的频域带宽索引之间存在对应关系；所述第一时间单元中包括的预定频域带宽中的所述控制信道元素包括的所述参考信号元素的个数和所述数据信道和/或信号包括的所述参考信号元素的个数满足预定条件；所述控制信道元素包括的所述参考信号元素的个数和所述数据信道和/或信号包括的所述参考信号元素的个数满足预定条件；所述控制信道元素为配置了传输配置指示信息TCI的控制信道元素，其中所述配置了TCI的控制信道元素表示所述控制信道元素关联一个TCI索引，一个TCI索引中包括一个或者多个准共址参考信号集合，如果所述控制信道元素中是直接通过配置 SSB(Synchronization Signal Block，同步信号块)索引得到准共址参考信号集合时，所述控制信道元素不满足所述第一预定特征；所述控制信道元素对应的准共址参考信号集合和同步信号的交集为空；所述控制信道元素对应的频域带宽处于激活状态；或者，所述控制信道元素对应至少一个激活的传输配置指示信息TCI，比如一个控制信道元素对应一个通过MAC-CE激活的TCI指示信息。
根据本公开提供的实施例，所述第二预定特征控制信道元素包括如下至少之一：所述第一时间单元中具有最低控制信道元素索引的控制信道元素；所述控制信道元素为配置了传输配置指示信息TCI的控制信道元素；所述控制信道元素对应至少一个激活的传输配置指示信息TCI；或，所述第一时间单元中满足第一预定特征的控制信道元素集合中具有最低控制信道元素索引的控制信道元素。
需要根据信令信息和/或约定规则确定第一时间单元的粒度信息，其中，所述第一时间单元的单元粒度包括如下之一：x个时域符号、y个时隙；其中，y为大于或者等于1的正整数，所述x满足如下特征至少之一：m个时隙中包括的时域符号个数是所述x的整数倍，所述m为大于或者等于1的正整数、所述x小于或者等于一个时隙中包括的时域符号个数、m个时隙中包括多于一个的所述第一时间单元粒度，不同第一时间单元粒度中包括的时域符号个数不同，或所述第一时间单元的单元粒度和所述数据信道和/或信号所在的索引信息有关联。
具体地，比如一个第一时间单元为一个slot中的2/4/7个时域符号，如图2所示一个第一时间单元为一个slot中的两个时域符号，一个slot中的索引最小的第一时间单元包括所述slot的第一个时域符号。比如PDSCH/AP-CSI-RS在索引为k+3第一时间单元中，包括CORESET且距离PDSCH/AP-CSI-RS最近的第一时间单 元为索引为k+2第一时间单元，则PDSCH/AP-CSI-RS的准共址参考信号集合为索引为k+2个第一时间单元中最低CORESET的准共址参考信号集合，即CORESET1的准共址参考信号集合。类似地，PDSCH/AP-CSI-RS在索引为k+5第一时间单元中，则PDSCH/AP-CSI-RS的准共址参考信号集合为索引为k+5个第一时间单元中最低CORESET的准共址参考信号集合，即CORESET0的准共址参考信号集合。
又如，如图3所示，一个第一时间单元为一个slot中的连续的4个时域符号，由于一个slot中包括14个时域符号，所以一个slot中最后一个第一时间单元(即索引为k+3的第一时间单元)中包括的时域符号个数为2个，即一个第一时间单元包括的时域资源不能跨slot。
再如，如图4所示，一个第一时间单元中为连续的4个时域符号，一个第一时间单元包括的时域符号可以跨slot。此时需要根据时隙单元索引，一个时隙中包括的时域符号个数(12/14)，确定一个第一时间单元中包括的时域符号，和/或第一时间单元的索引。2个时隙中包括整数倍个第一时间单元，则第n个时隙中索引为l的时域符号所在的第一时间单元索引为

根据本公开提供的实施例，一个PDSCH的不同DMRS端口组/AP-CSI-RS的不同CSI-RS端口组，对应的第一时间单元的单元粒度不同，比如第一端口组对应的第一时间单元的单元粒度为一个slot，第二端口组对应的第一时间单元的单元粒度为2个时域符号，则第一端口组的准共址参考信号包括满足第一预定特征的控制信道元素且距离PDSCH/AP-CSI-RS最近的slot中的满足第二预定特征的控制信道元素的一个或者多个准共址参考信号，第二端口组的准共址参考信号包括满足第一预定特征的控制信道元素且距离PDSCH/AP-CSI-RS最近的图2中的第一时间单元(即所述一个第一时间单元中包括2个时域符号)中的满足第二预定特征的控制信道元素的一个或者多个准共址参考信号。
根据本公开提供的实施例，一个PDSCH/AP-CSI-RS对应的第一时间单元的单元粒度和调度所述PDSCH/AP-CSI-RS的控制信道的RNTI有关，比如C-RNTI的时候，第一时间单元的单元粒度为一种取值，MCS-C-RNTI的时候，第一时间单元的单元粒度为另一种取值。
根据本公开提供的实施例，通过对第一时间单元粒度的灵活配置和确定，可有效增加默认波束的灵活度。

在场景1中，PDSCH/AP-CSI-RS包括的端口组个数c小于PDCCH包括的端口组个数d，此时需要信令信息确定PDSCH/AP-CSI-RS的第i个端口组对应PDCCH的端口组索引，比如所述第i个端口组对应PDCCH的{第j1，第j2}端口组，PDSCH/AP-CSI-RS的第i个端口组的准共址参考信号根据与其存在对应关系的所述PDCCH的{第j1，第j2}端口组的准共址参考信号获取，或者所述第i个端口组对应PDCCH的{第j1}端口组，PDSCH/AP-CSI-RS的第i个端口组的准共址参考信号根据与其存在对应关系的所述PDCCH的{第j1}端口组的准共址参考信号获取。其中j1，j2属于{0，...，d-1}或者j1，j2属于{1，...，d}。

在场景3中，PDSCH/AP-CSI-RS包括的端口组个数c大于PDCCH包括的端口组个数c，此时需要信令信息确定PDSCH/AP-CSI-RS的第i个端口组对应PDCCH的端口组索引， 比如PDSCH/AP-CSI-RS的前d个端口组的准共址参考信号集合分别根据PDCCH的d个端口组中一个端口组的准共址参考信号获取，PDSCH/AP-CSI-RS的其余c-d个端口组的准共址参考信号集合根据PDCCH所在的CORESET中配置的第二类准共址参考信号集合获取。
在场景4中，PDSCH/AP-CSI-RS包括的端口组个数c等于PDCCH包括的端口组个数c，所述d大于1，此时需要信令信息确定PDSCH/AP-CSI-RS的第i个端口组对应PDCCH的端口组索引，其中PDSCH/AP-CSI-RS的第i个端口组的准共址参考信号集合根据与第i个端口组存在对应关系的PDCCH端口组的准共址参考信号集合获取。
