Description

参数重置方法及装置、参数信息的接收方法及装置 技术领域
本公开涉及通信领域，具体而言，涉及一种参数重置方法及装置、参数信息的接收方法及装置。
背景技术
第五代移动通信系统新空口技术(new radio，简称NR)的关键特征之一就是支持高频段，高频段有丰富的频域资源，但是存在无线信号衰减快导致覆盖小的问题。波束方式发送信号可以将能量聚集在比较小的空间范围，改善高频段信号的覆盖问题。在波束场景下，随着时间和位置的变化，基站与UE之间的波束对也可能发生变化，因此需要灵活的波束更新机制。当通信波束发生变化时，通过MAC CE更新波束以及对应链路的测量路损的RS信息(PL-RS参数)相较于高层参数的更新，灵活性更高。本公开的方案主要用于解决MAC CE更新PL-RS参数的机制的存在的问题。
当通信波束发生变化时，可以通过MAC CE更新波束以及对应链路的测量路损的RS信息(PL-RS参数)，由于PL是高层参数滤波的结果，需要多次测量，因此PL生效的时延比新波束生效的时延大。在新波束生效，而还使用老波束的PL的过程中，闭环功控很可能会累积较大的负值，导致新波束的PL生效后发送功率骤降的问题。
针对相关技术中，在新波束生效，而还使用老波束的PL的过程中，闭环功控很可能会累积较大的负值，导致新波束的PL生效后发送功率骤降的问题等问题，尚未提出有效的解决方案。

为了更好的理解上述实施例中的参数重置过程，参数信息的接收过程，以下结合实例对上述技术方案进行说明，但不用于限定本公开实施例的技术方案。
实例1：闭环功控reset
在相关技术中，基站与UE之间的通信波束发生变化时，可以通过MAC CE更新波束状态。对于上行传输，确定发送功率的路损值是通过下行RS测量的。当基站与UE之间的通信波束发生变化时，也可以通过MAC CE更新路损测量参数，其中，路损又称为路径损耗(Pathloss，简称为PL)；路损测量参数，包括测量PL的RS指示信息，也可以简写为PL-RS参数。
波束状态至少包括下述之一：准共址QCL状态，传输配置指示TCI状态，空间关系信息，参考信号信息(例如，SRI，SRS resource Indicator)，空间滤波器信息，预编码信息。
在基站与UE之间的通信波束发生变化时，MAC CE需要更新后续传输的波束状态，也需要更新后续上行传输相关的PL-RS参数。
一般地，MAC CE信息的生效时间为，UE接收到MAC CE信息后，反馈ACK信息给基站，发送包含ACK信息的上行传输之后的一段时间 T0后MAC CE信息生效。T0可以是3ms，或3个slot，3个子帧等。而MAC CE更新PL的生效时间却有其特殊性，因为PL是L3(层3，高层)的测量结果，更新为一个之前没有激活的PL-RS参数时，需要多次PL-RS的测量结果进行滤波才能获得一个比较可靠的PL值。因此更新PL-RS的MAC CE的生效时间比一般的MAC CE的生效时间晚。因此，更新PL-RS的MAC CE的生效时间在上述MAC CE的生效时间后再延迟K个PL-RS的发送所需时间。
如图7所示，假设在t1时刻，MAC CE更新波束状态生效，在t2时刻，MAC CE更新PL-RS生效。在t1时刻之后，传输使用新的波束状态确定发送方式，例如发送波束，预编码参数等。在t2时刻之后，新波束状态对应的PL-RS才能生效。老波束状态用beam1表示，新波束状态用beam2表示，新波束状态beam2的PL值比老波束状态beam1的PL值小。在t1到t2时刻之间，传输使用新的波束状态beam2，理应使用与之匹配的PL值，但是由于beam2的PL值还没有稳定，因此未生效，所以只能使用beam1的PL值，因此存在实际传输链路的PL较小，而UE在确定上行传输的发送功率时所使用的PL值偏大(比实际的大)。因此，可以预见，在t1时刻到t2时刻，基站会通过闭环功控TPC命令将上行传输的发送功率调低。假设在t2时刻，UE已经通过几次负值的TPC命令累积效果将beam1与beam2之间的PL的之差完全补偿了，或者实现了一定程度的补偿，则在t2时刻，beam2的PL值生效时，UE的闭环功控部分(即功率控制调节状态，power control adjustment state)预期是一个较大的负值。本来应该在t2时刻开始beam2的PL值与beam2作为实际发送的波束实现了匹配，但是此时UE的闭环功控部分体现了历史TPC命令的累积，并且预期有很大的负值，将会对t2时刻切换了PL之后功率造成不好的影响。很大可能UE计算的发送功率低于实际链路的需求功率。
在本公开可选实施例中，更新PL-RS参数的信息对应的PL生效后，闭环功控相关参数被重置。
进一步地，通过以下信令之一承载更新PL-RS参数的信息：RRC信令、MAC CE、物理层信令。
下面以MAC CE承载更新PL-RS参数的信息举例。
承载更新PL-RS参数的MAC CE对应的PL生效，包括：
当以下条件至少之一被满足时，新的PL-RS对应的PL在第一时间之后生效：PL-RS被配置总数为X个以上，其中X为正整数，例如4；新的PL-RS不是激活的PL-RS
所述第一时间由以下至少之一的方式确定：收到更新PL-RS的MAC CE之后回复ACK响应；等待新的PL-RS发送K次；K为大于或等于1的整数，例如5。等待T时间之后。T时间是指一个或多个预定的时间单位，所述预定的时间单位包括以下之一：无线帧、子帧、时隙(slot)、符号(即OFDM符号)、秒、毫秒、微秒。例如，T时间为2毫秒，3个子帧。
第一时间的确定方式举例：如图8所示，UE在收到承载更新PL-RS参数以及更新波束状态的MAC CE之后响应HARQ-ACK，之后过3个子帧，此时更新的波束状态开始生效，即新波束开始生效，但是此后过一段时间，例如5个更新的PL-RS参数对应的RS发送至少5次，再等待T时间，例如2毫秒，更新的PL-RS参数对应的PL生效。
进一步地，闭环功控相关参数，包括：新的PL-RS参数对应的闭环功控编号对应的功率控制调整状态。
进一步地，根据新的PL-RS参数确定闭环功控编号。包括：根据新的PL-RS参数编号确定闭环功控编号，或根据新的PL-RS参数与闭环功控编号的关联关系确定闭环功控编号。
PL-RS参数与闭环功控编号的关联关系，包括以下之一：PL-RS参数编号与闭环功控编号具有关联关系；PL-RS参数编号与闭环功控编号分别与同一波束状态具有关联关系；PL-RS参数编号与闭环功控编号配置在同 一关联关系结构中。
对PUSCH传输，波束状态包括：SRI，或SRI-PUSCH-PowerControl编号，TCI状态。
对PUSCH传输，关联关系结构包括：SRI-PUSCH-PowerControl，或TCI状态与功控参数关联关系。
具体地，闭环ID由指示更新的PL-RS对应的SRI在高层参数SRI-PUSCH-PowerControl中对应的sri-PUSCH-ClosedLoopIndex确定。
更新的PL-RS对应的SRI是指更新PL-RS的MAC CE中包含的SRI。
在本公开实施例的另一个可选实施例中，更新波束状态的信息对应的波束状态生效后，闭环功控相关参数被重置。
进一步地，通过以下信令之一承载更新波束状态的信息：RRC信令、MAC CE、物理层信令。
下面以MAC CE承载更新波束状态的信息举例。
承载更新波束状态的信息的MAC CE对应的波束状态生效，包括：
当以下条件至少之一被满足时，更新的波束状态在第二时间之后生效：
所述第二时间由以下至少之一的方式确定：收到更新波束状态的MAC CE之后回复ACK响应；等待T时间之后。T时间是指一个或多个预定的时间单位，所述预定的时间单位包括以下之一：无线帧、子帧、时隙(slot)、符号(即OFDM符号)、秒、毫秒、微秒。例如，T时间为2毫秒，3个子帧。
第二时间的确定方式举例：如图8所示，UE在收到承载更新波束状态的MAC CE之后响应HARQ-ACK，之后过3个子帧，更新的波束状态开始生效。
进一步地，闭环功控相关参数，包括：更新的波束状态对应的闭环功 控编号对应的功率控制调整状态。
进一步地，根据更新的波束状态确定闭环功控编号。包括：根据更新的波束状态编号确定闭环功控编号，或根据更新的波束状态与闭环功控编号的关联关系确定闭环功控编号。
波束状态与闭环功控编号的关联关系，包括以下之一：波束状态编号与闭环功控编号具有关联关系；波束状态编号与闭环功控编号配置在同一关联关系结构中。
行传输的波束状态与空间关系的关联被MAC CE配置，和/或所述波束状态与PL-RS的关联被MAC CE配置，参考该波束状态的上行传输的闭环功控相关参数被重置。
进一步地，上行传输的波束状态与空间关系的关联被MAC CE配置，和/或所述波束状态与PL-RS的关联被MAC CE配置，更新波束状态的信息对应的波束状态生效后，参考该波束状态的上行传输的闭环功控相关参数被重置。
进一步地，上行传输的波束状态与空间关系的关联被MAC CE配置，和/或所述波束状态与PL-RS的关联被MAC CE配置，更新波束状态的信息对应的PL-RS所对应的PL生效后，参考该波束状态的上行传输的闭环功控相关参数被重置。
例如，在图7中，t1时刻新的波束状态生效，而新波束状态对应的PL还没有生效，导致在t1到t2之间，波束状态与PL不匹配。解决该问题的方法还包括，对在t1时刻到t2时刻之间的上行传输使用平稳过渡的PL值，防止或减轻在t2时刻切换PL值导致闭环功控累积量(功率控制调整状态)引起的性能突降。
在t1时刻之前，根据上行传输关联的老的PL-RS的PL确定上行传输的PL；
在t2时刻之后，根据上行传输关联的新的PL-RS的PL确定上行传输 的PL；
在t1到t2时刻之间，根据以下之一确定上行传输的PL：
上行传输关联的老的PL-RS的PL；
上行传输关联的新的PL-RS的L1-PL；
上行传输关联的新的PL-RS的至少一个L1-PL的高层滤波PL值；
上行传输关联的老的PL-RS的PL与上行传输关联的新的PL-RS的至少一个L1-PL的高层滤波PL值；
上行传输关联的老的PL-RS的至少一个L1-PL与上行传输关联的新的PL-RS的至少一个L1-PL的高层滤波PL值。
其中，上行传输关联的老的PL-RS的PL是t1时刻或t1时刻之前上行传输关联的老的PL-RS的PL值；
上行传输关联的老的PL-RS的至少一个L1-PL是t1时刻之前上行传输关联的老的PL-RS的至少一个RS样本(sample)对应的L1-PL值。
上行传输关联的新的PL-RS的至少一个L1-PL是t1时刻及t1时刻之后上行传输关联的新的PL-RS的至少一个RS样本对应的L1-PL值。
在本公开一实施例中，在本公开可选实施例中，更新PL-RS参数信息中还是只包含一个PL-RS信息，但是为了区分新的PL-RS和原来的旧的PL-RS，所以用了第二PL-RS参数和第一PL-RS。
实例2：快速更新PL-RS的方法
需要说明的而是，由基站保证激活的PL-RS的数量不大于预定数值
基站通过RRC信令为UE配置PL-RS参数池，其中包括至少一个PL-RS参数。
基站还通过RRC信令为UE配置上行信道、信号的PL-RS参数，不同PL-RS的数量不超过预定数值，例如，4。
基站可以通过MAC信令(即MAC CE)为UE的上行传输更新PL-RS参数。
当上行传输是PUSCH传输时，MAC信令指示PUSCH的波束状态信息，例如SRI，与PL-RS的关联；
当上行传输是PUCCH传输时，MAC信令指示PUCCH的波束状态信息，例如PUCCH的空间关系(spatial-relation)，与PL-RS的关联；
当上行传输是SRS传输时，MAC信令指示SRS的波束状态信息，例如SRS资源集合，与PL-RS的关联。
由基站保证激活的PL-RS的数量不大于预定数值。例如，原本有4个激活的PL-RS，分别有PL-RS ID 1～4标识，在某一时刻，PL-RS ID 5需要被激活，则PL-RS ID 1～4中需要有至少一个被去激活。假设PL-RS ID 1被去激活，则基站需要通过对之前关联到PL-RS ID 1的上行传输重新关联到新的PL-RS集合中，例如PL-RS ID 2～5。基站以此维持UE的激活状态的PL-RS数量不大于预定数值。
针对相关技术中存在的MAC CE的开销大。当通信链路发生变化，需要切换波束时，很大可能也需要更换上行传输的PL-RS参数。在现有相关技术中，需要对不同的传输分别用MAC CE更新PL-RS参数。例如，对受到影响的PUSCH传输通过MAC CE对某一个或多个SRI配置新的PL-RS，不仅包括新激活的PL-RS参数，还包括去激活的PL-RS参数。对PUCCH也可能需要一个或多个MAC CE对某一个或多个PUCCH的空间关系(组)更改PL-RS参数。对SRS也可能需要一个或多个MAC CE对某一个或多个SRS资源集合更换PL-RS参数。
此外，当不同MAC CE在不同的时刻发送，且对应的PL-RS一致时，不同的MAC CE所更新的PL-RS的参数的生效时延不同(生效时间点可 能相同或不同)。
进一步地，在载波聚合(Carrier Aggregation)场景，多个CC(成员载波，component carrier)之间的上行传输的相同波束状态所对应的实际波束可能不同，例如，CC1的PUSCH的SRI1的波束与CC2的PUSCH的SRI1的波束可能不同，因此不容易实现多个CC统一更新某一波束状态的PL-RS参数。
在本公开可选实施例中，基站发送PL-RS参数更新信息给UE，用于更新上行传输的PL-RS参数。
PL-RS参数更新信息包括以下信息：第一PL-RS参数，第二PL-RS参数。对预定的上行传输，用第二PL-RS参数取代第一PL-RS参数。
PL-RS参数更新信息通过以下之一信令承载：RRC信令、MAC CE信令、物理层信令。
上行传输包括以下至少之一：PUSCH传输、PUCCH传输、SRS传输。
通过预定的方式，或配置(指示)的方式确定PL-RS更新信息对应的上行传输。
具体地，通过预定的方式，或配置(指示)的方式确定预定的上行传输包括PUSCH传输、PUCCH传输、或SRS传输中的一种、多种、或所有。
通过配置的方式确定PL-RS更新信息对应的上行传输的情况下，预定的上行传输包括，PUSCH传输、PUCCH传输、或SRS传输中的一种、多种、或所有的。配置(指示)信息通过以下之一信令承载：RRC信令、MAC CE信令、物理层信令。
例如，MAC CE指示的PL-RS更新信息仅用于PUSCH传输。则PUSCH传输的波束状态与PL-RS参数的关联关系中与MAC CE中包含的第一PL-RS参数相同的关联关系被替换为第二PL-RS参数。假设PUSCH传输 的波束状态与PL-RS参数的关联关系包括：关联关系1：SRI0与PL-RS0关联；关联关系2：SRI1与PL-RS1关联；关联关系3：SRI2与PL-RS2关联。UE接收到更新PL-RS的MAC CE中包含的第一PL-RS是PL-RS1，第二PL-RS是PL-RS4。则该MAC CE更新PL-RS的结果是：关联关系2变成：SRI1与PL-RS4关联。
又如，MAC CE指示的PL-RS更新信息用于PUSCH传输、PUCCH传输、以及SRS传输。假设PUSCH传输的波束状态与PL-RS参数的关联关系包括：PUSCH关联关系1：SRI0与PL-RS0关联；PUSCH关联关系2：SRI1与PL-RS1关联；PUSCH关联关系3：SRI2与PL-RS2关联。PUCCH传输的波束状态与PL-RS的关联关系包括：PUCCH关联关系1：PUCCH空间关系0与PL-RS0关联；PUCCH关联关系2：PUCCH空间关系1与PL-RS1关联。SRS与PL-RS的关联包括：SRS关联关系1：SRS资源集合0与PL-RS0关联；SRS关联关系2：SRS资源集合1与PL-RS1关联。UE接收到更新PL-RS的MAC CE中包含的第一PL-RS是PL-RS1，第二PL-RS是PL-RS4。则该MAC CE更新PL-RS的结果是：PUSCH关联关系2：SRI1与PL-RS4关联；PUCCH关联关系2：PUCCH空间关系1与PL-RS4关联；SRS关联关系2：SRS资源集合1与PL-RS4关联，其他的关联关系不变。
进一步地，通过预定的方式、或配置的方式确定PL-RS更新信息对应的上行传输的部分或全部关联关系。
进一步地，PL-RS更新信息作用的上行传输的所有关联关系中的部分或全部关联关系由以下方式之一指示：比特地图；关联关系中的编号最小的N0个；关联关系中的编号最大的N1个。其中N0、N1是大于或等于1的整数。
例如，假设PUSCH传输的波束状态与PL-RS参数的关联关系包括：PUSCH关联关系1：SRI0与PL-RS0关联；PUSCH关联关系2：SRI1与PL-RS1关联；PUSCH关联关系3：SRI2与PL-RS2关联。
当PL-RS更新信息作用的上行传输的所有关联关系中的部分或全部关联关系由比特地图指示时，比特地图的有效长度为3，分别表示PUSCH关联关系1～3是否被PL-RS更新信息影响。例如，比特地图010表示PUSCH关联关系2会被PL-RS更新信息影响，即PL-RS更新信息中的第一PL-RS参数与PUSCH关联关系2中的PL-RS参数相同时，PUSCH关联关系2中的PL-RS参数被更新为第二PL-RS参数。而PUSCH关联关系1和3则不受影响。
当PL-RS更新信息作用的上行传输的所有关联关系中的部分或全部关联关系由关联关系中的编号最小的N0个指示时，例如，N0取值为1时，即PL-RS更新信息中的第一PL-RS参数与PUSCH关联关系1中的PL-RS参数相同时，PUSCH关联关系1中的PL-RS参数被更新为第二PL-RS参数。而PUSCH关联关系2和3则不受影响。
通过预定的方式，或配置的方式确定PL-RS更新信息对应的上行传输的所属的小区(也称为载波)、或BWP(bandwidth part，带宽部分)。
PL-RS更新信息对应的上行传输的所属的小区包括：PL-RS更新信息的传输资源相关的小区(组)、特定小区(组)、配置的小区(组)、或所有激活的小区。
其中，PL-RS更新信息的传输资源相关的小区(组)包括：PL-RS更新信息的传输资源所在的小区(组)，或PL-RS更新信息的传输资源所在的小区对应的上行小区(组)。

配置的小区(组)是指基站配置给UE小区编号，或小区编号列表相关信息，用于指示PL-RS更新信息对应的上行传输的所属的小区。
PL-RS更新信息对应的上行传输的所属的BWP包括：PL-RS更新信 息的传输资源相关的BWP、激活的BWP。
其中，PL-RS更新信息的传输资源相关的BWP包括：PL-RS更新信息的传输资源所在的BWP，或PL-RS更新信息的传输资源所在的BWP对应的上行BWP。
