Description

发射功率差值的指示方法及装置、功率补偿方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种发射功率差值的指示方法及装置、功率补偿方法及装置、基站、用户设备和计算机可读存储介质。
背景技术
随着无线通信技术的飞速发展，出现了第五代移动通信技术(5th Generation，简称为5G)。在最近的第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)讨论中，没有给出同步块(SSB)之后的剩余关键系统信息(RMSI)的物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)和SSB的功率差值，只定义该功率差值最大为6分贝(dB)。在解析过程中，因为需要先解析出PDCCH才能解析出RMSI，所以不能在RMSI中指示该功率差值。而物理广播信道(PBCH)内容已经全部确定，故不能加入指示该功率差值的信息。如果该功率差值在3dB以内，对用户设备(UE)解析PDCCH的影响较小。但是如果该功率差值较大，例如达到6dB，则会大大提升PDCCH的解码错误率。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是本申请一示例性实施例示出的一种发射功率差值的指示方法的流程图，该实施例从基站侧进行描述，如图1所示，该发射功率差值的指示方法包括：
在步骤S101中，若SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值，则依次将连续预设数量SSB中的主同步信号(PSS)发射功率设置为预设的固定模式，固定模式用于指示发射功率差值大于预设阈值。
其中，预设阈值可以根据需要设置，例如可以为3dB。预设数量可以根据需要灵活设置，例如可以为3个、4个等。
如图2所示，SSB20包括PSS21、辅参考信号(SSS)22、物理广播信道(PBCH)23和用来解调PBCH的解调参考信号(DMRS)24，其中，SSS22、PBCH23及DMRS24的发射功率一致，PSS21发射功率没有限定，因此，该实施例中，可以通过将连续预设数量SSB中PSS发射功率设置为预设的固定模式来隐含地表示发射功率差值大于预设阈值。
例如，可以将连续4个SSB中PSS发射功率设置为高低高低模式或者低高低高模式。
在步骤S102中，以波束扫描的方式向UE发送SSB。
在该实施例中，基站以波束扫描的方式向UE发送SSB，这样，UE接收到SSB后，可以通过对连续接收到的SSB进行解析，以判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式，进而判断出发射功率差值是否大于预设阈值，从而在发射功率差值大于预设阈值时，对PDCCH的发射功率进行补偿。
上述实施例，通过依次将连续预设数量SSB中的PSS发射功率设置为预设的固定模式来指示SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值，并向UE发送SSB，使得UE在接收SSB之后，通过对SSB进行解析可以确定连续预设数量SSB中的PSS发射功率是否符合预设的固定模式，并在PSS发射功率符合预设的固定模式时，确定发射功率差值大于预设阈值，对PDCCH的发射功率进行补偿，从而大大降低PDCCH的解码错误率。
图3是本申请一示例性实施例示出的一种功率补偿方法的流程图，该实施例从UE侧进行描述，如图3所示，该功率补偿方法包括：
在步骤S301中，接收基站发送的SSB。
在步骤S302中，对连续接收到的预设数量SSB进行解析，以获得连续预设数量SSB中的PSS发射功率。
其中，预设数量可以根据需要灵活设置，例如可以为3个、4个等。
在该实施例中，UE可以对连续接收到的4个SSB进行解析，从而得到连续4个SSB中PSS发射功率。
在步骤S303中，判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式。
其中，判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式，可以包括：检测连续预设数量SSB中所有相邻SSB中PSS发射功率的差值是否均大于预设数值；若上述差值均大于或等于预设数值，则可以根据连续预设数量SSB中PSS发射功率的大小关系判断连续预设数量SSB中PSS发射功率是否符合固定模式。若任一差值小于预设数值，则无法根据连续预设数量SSB中PSS发射功率的大小关系判断连续预设数量SSB中PSS发射功率是否符合固定模式。
其中，预设数值可以根据需要灵活设置，例如可以为2dB。
例如，预设数值为2dB，预设的固定模式为高低高低模式，UE获得的连续4个SSB中 PSS发射功率分别为100dB、97dB、100dB、97dB，由于所有相邻SSB中PSS发射功率的差值均大于2dB，因此，可以根据连续4个SSB中PSS发射功率的大小关系确定连续预设数量SSB中PSS发射功率符合预设的固定模式。
需要说明的是，UE还可以自定义拟合基站的PSS发射可能性，例如，当UE检测到连续4个SSB中PSS发射功率分别为100dB、97dB、100dB、98dB，即PSS发射功率为高低高略低模式，则可以认为连续4个SSB中PSS发射功率也符合固定模式。
又例如，预设数值为2dB，预设的固定模式为高低高低模式，UE获得的连续4个SSB中PSS发射功率分别为99dB、98dB、99dB、98dB，由于相邻SSB中PSS发射功率的差值为1dB，1dB小于预设数值，因此，无法根据连续4个SSB中PSS发射功率的大小关系判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式。
在步骤S304中，若连续预设数量SSB中PSS发射功率符合固定模式，则确定SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值。
在该实施例中，若UE确定连续预设数量SSB中PSS发射功率符合固定模式，则可以确定SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值。
在步骤S305中，在接收PDCCH时，对PDCCH的发射功率进行补偿。
若SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值，则可以在接收PDCCH时，对PDCCH的发射功率进行补偿，以大大降低PDCCH的解码错误率。
上述实施例，通过接收基站发送的SSB，对SSB进行解析，以确定连续预设数量SSB中的PSS发射功率是否符合预设的固定模式，并在PSS发射功率符合预设的固定模式时，确定发射功率差值大于预设阈值，对PDCCH的发射功率进行补偿，从而大大降低PDCCH的解码错误率。
图4是本申请一示例性实施例示出的一种功率补偿方法的信令流程图，该实施例从UE和基站交互的角度进行描述，如图4所示，该功率补偿方法包括：
在步骤S401中，若SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值，则基站依次将连续预设数量SSB中的PSS发射功率设置为预设的固定模式，该固定模式用于指示发射功率差值大于预设阈值。
在步骤S402中，基站以波束扫描的方式向UE发送SSB。
在步骤S403中，UE接收基站发送的SSB。
在步骤S404中，UE对连续接收到的预设数量SSB进行解析，以获得连续预设数量SSB中的PSS发射功率。
在步骤S405中，UE判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式。
在步骤S406中，若连续预设数量SSB中PSS发射功率符合固定模式，则UE确定SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值。
在步骤S407中，UE在接收PDCCH时，对PDCCH的发射功率进行补偿。
上述实施例，通过基站和UE之间的交互，使得UE可以确定连续预设数量SSB中的PSS发射功率是否符合预设的固定模式，并在PSS发射功率符合预设的固定模式时，确定发射功率差值大于预设阈值，并对PDCCH的发射功率进行补偿，从而大大降低PDCCH的解码错误率。

其中，预设阈值可以根据需要设置，例如可以为3dB。预设数量可以根据需要灵活设置，例如可以为3个、4个等。
如图2所示，SSB20包括PSS21、辅参考信号(SSS)22、物理广播信道(PBCH)23和用来解调PBCH的解调参考信号(DMRS)24，其中，SSS22、PBCH23及DMRS24的发射功率一致，PSS21发射功率没有限定，因此，该实施例中，可以通过将连续预设数量SSB中PSS发射功率设置为预设的固定模式来隐含地表示发射功率差值大于预设阈值。
例如，可以将连续4个SSB中PSS发射功率设置为高低高低模式或者低高低高模式。
发送模块52被配置为以波束扫描的方式向用户设备UE发送设置模块51将PSS发射功率设置为固定模式的SSB。
在该实施例中，基站以波束扫描的方式向UE发送SSB，这样，UE接收到SSB后，可以通过对连续接收到的SSB进行解析，以判断连续预设数量SSB中PSS发射功率是否符合预设的固定模式，进而判断出发射功率差值是否大于预设阈值，从而在发射功率差值大于预设阈值时，对PDCCH的发射功率进行补偿。
上述实施例，通过依次将连续预设数量SSB中的PSS发射功率设置为预设的固定模式来指示SSB与该SSB对应RMSI的PDCCH的发射功率差值大于预设阈值，并向UE发送SSB，使得UE在接收SSB之后，通过对SSB进行解析可以确定连续预设数量SSB中的PSS发射功率是否符合预设的固定模式，并在PSS发射功率符合预设的固定模式时，确定发射功率差值大于预设阈值，对PDCCH的发射功率进行补偿，从而大大降低PDCCH的解码错误率。

其中，预设数值可以根据需要灵活设置，例如可以为2dB。
例如，预设数值为2dB，预设的固定模式为高低高低模式，UE获得的连续4个SSB中PSS发射功率分别为100dB、97dB、100dB、97dB，由于所有相邻SSB中PSS发射功率的差值均大于2dB，因此，可以根据连续4个SSB中PSS发射功率的大小关系确定连续预设数量SSB中PSS发射功率符合预设的固定模式。
需要说明的是，UE还可以自定义拟合基站的PSS发射可能性，例如，当UE检测到连续4个SSB中PSS发射功率分别为100dB、97dB、100dB、98dB，即PSS发射功率为高低高略低模式，则可以认为连续4个SSB中PSS发射功率也符合固定模式。
