Description

一种上报或接收用户设备能力的方法、装置及可读存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种上报或接收用户设备能力的方法、装置及可读存储介质。
背景技术
无线通信技术中，多入多出(multiple input multiple output，MIMO)是为极大地提高信道容量，在发送端和接收端都使用多根天线，在收发之间构成多个信道的天线系统。
载波聚合(Carrier Aggregation，CA)技术通过聚合载波的方式提高传输带宽。
载波聚合的方式包括：
方式一，带内连续的载波聚合：其相应的成员载波位于同一频带，并且频谱连续。
方式二，带内不连续的载波聚合：其相应的成员载波位于同一频带，但频谱不连续。
方式三，带外不连续的载波聚合：其相应的成员载波位于不同的频面，并且频谱不连续。
不同的用户设备可以支持不同的发射功率等级，即相应的功率放大器(PA)的额定功率不同。
例如：
发射功率等级为Power Class 3，简称为PC3，对应于23dBm。
发射功率等级为Power Class 2，简称为PC2，对应于26dBm。
一些用户设备可以同时支持上行(UpLink，UL)多入多出(MIMO)技术和带内连续(Intra-Band Contiguous)的上行(UpLink，UL)载波聚合(Carrier Aggregation，CA)技术，这一特性除了支持PC3的发射功率等级也可用于支持高功率(如PC2)的发射功率等级。
用户设备在单载波模式下支持UL MIMO时，通过IE ue-PowerClass上报其功率等级。
用户设备在多载波模式下支持UL MIMO时，通过IE PowerClass上报其功率等级。
当用户设备通过IE ue-PowerClass和IE PowerClass上报的功率等级不一致时，以IE ue-PowerClass携带的功率等级为准，即IE ue-PowerClass中的功率等级会覆盖IE PowerClass上报的功率等级。
用户设备同时支持上行MIMO和带内连续的上行载波聚合时，通过IE maxNumberMIMO-LayersCB-PUSCH上报支持的UL MIMO的层数，并且在其支持发射分集(TxD)时，通过IE Tx txDiversity-r16上报。

以上所示用户设备102可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备102可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备101进行通信(如无线通信)，并接受网络设备101提供的网络服务，这里的网络设备101包括但不限于图示基站。
其中，用户设备102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、个人数字处理personal digital assistant，PDA)设备、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、未来5G网络中的用户设备或者未来演进的PLMN网络中的用户设备等。

表1
Arch intra‐band C UL CA UL MIMO
#1 2 PC3 PA+1LO PC3
#2 2 PC3 PA+1LO PC2
#3 2 PC2 PA+1LO PC2
#4 PC3 PA+PC2 PA+1LO PC2
从而表1中只有#2对应的用户设备才会上报TxD。
当网络设备接收用户设备的下述上报：
上报支持的UL MIMO的层数为2(例如通过IE maxNumberMIMO-LayersCB-PUSCH上报值为2)；由于本公开的目的在于终端支持UL CA的同时要支持UL MIMO，因此需要先上报支持的UL MIMO的层数。在此基础上上报多载波系统的功率等级。
上报多载波系统的功率等级为PC2(例如通过IE maxNumberMIMO-LayersCB-PUSCH上报值为2)；
上报支持TxD(例如通过IE Tx txDiversity-r16上报支持TxD)；
可以根据表1确定用户设备的实现结构为#2对应的2 PC3PA+1LO。
但是，当网络设备接收用户设备的上报支持的UL MIMO的层数为2，以及，上报多载波系统的功率等级为PC2，以及未上报支持TxD时，仅可以识别用户设备的实现结构中至少对应于一PC2的PA，根据表1只能确定可能对应于#3中的“2 PC2 PA+1LO”或者#4中的“PC3+PC2+1LO”，但无法准确确定对应于两者中的哪一个。此两种结构的射频指标可能不同，尤其是MPR，在无法准确定对应于两者中的哪一个时，会影响到确定Pcmax的下限值的准确上报。

终端可以同时支持UL MIMO和带内连续的上行载波聚合，这一特性除了支持PC3的发射功率等级也可用于支持高功率终端如PC2的发射功率等级，对应终端的可能的实现方式如下表所示
Arch intra-band C UL CA UL MIMO
#1 2 PC3 PA+1LO PC3
#2 2 PC3 PA+1LO PC2
#3 2 PC2 PA+1LO PC2
#4 PC3 PA+PC2 PA+1LO PC2
当终端工作在单载波的模式下，其发射功率等级通过IE ue-PowerClass信令per UE进行上报，具体信令上报路径为UE-NR-Capability->RF-Parameters->supportedBandListNR->ue-PowerClass:ENUMERATED{pc1,pc2,pc3,pc4}，PC3是默认的终端支持的功率等级。
当终端工作在多载波系统模式下，即终端在该频带内有多个服务小区，或者在其他频带内也有服务小区，终端在所有服务小区的总的发射功率的发射功率等级通过IE PowerClass信令per band combination per UE进行上报，具体信令上报路径为UE-NR-Capability->RF-Parameters->supportedBandCombinationList->powerClass-v1530:ENUMERATED{pc2}/powerClass-v1610:ENUMERATED{pc1dot5}，PC3是默认的终端支持的功率等级。当IE ue-PowerClass和IE PowerClass上报的功率等级不一致时，IE PowerClass上报的功率等级会覆盖掉IE ue-PowerClass上报的功率等级。
此外，终端支持的UL MIMO的层数是通过IE FeatureSetDownlinkPerCC上报的，具体信令上报路径为UE-NR-Capability->FeatureSets->FeatureSetUplinkPerCC->maxNumberMIMO-LayersCB-PUSCH：MIMO-LayersUL/maxNumberMIMO-LayersNonCB-PUSCH：MIMO-LayersUL。且此路径中UL MIMO能力的上报没有关联任何功率等级的上报。
因此当终端在单载波的模式下支持UL MIMO时，其功率等级通过IE ue-PowerClass进行上报。如果在多载波系统中支持UL MIMO时，其功率等级通过IE PowerClass进行上 报。当IE ue-PowerClass和IE PowerClass上报的功率等级不一致时，IE PowerClass上报的功率等级会覆盖掉IE ue-PowerClass上报的功率等级。
当终端同时支持UL MIMO和带内连续的上行载波聚合时，通过IE maxNumberMIMO-LayersCB-PUSCH＝2上报支持2层的UL MIMO，通过IE ue-PowerClass和IE PowerClass上报支持PC2时，终端可以采用三种不同的实现方法，如2 PC3PA+1LO，2 PC2 PA+1LO，1x23dBm PA+1x26dBm PA+1LO，而且不同的实现结构需要满足不同的射频指标，相应的功控也不一样。但是基于目前的信令无法准确区分终端的实现方法。
目前仅允许只有PC2支持2 PC3 PA+1LO的终端和PC1.5支持2 PC2 PA+1LO的终端才能上报TxD。
因此当终端通过IE maxNumberMIMO-LayersCB-PUSCH＝2上报支持2层的UL MIMO，通过IE ue-PowerClass和IE PowerClass上报支持PC2，通过IE Tx txDiversity-r16上报支持TxD时，可以识别终端的实现结构为2 PC3 PA+1LO。
当终端通过IE maxNumberMIMO-LayersCB-PUSCH＝2上报支持2层的UL MIMO，通过IE ue-PowerClass和IE PowerClass上报支持PC2，且不上报支持TxD时，仅可识别终端的实现结构中至少有一个26dBm PA，即2 PC2 PA+1LO，1x23dBm PA+1x26dBm PA+1LO，无法进一步区分2 PC2 PA+1LO和1x23dBm PA+1x26dBm PA+1LO，但这两种结构的射频指标有可能是不一样的，特别是MPR，这会影响到Pcmax的下限值。
当终端同时支持UL MIMO和带内连续的上行载波聚合时，对于高功率终端现有信令无法指示终端的不同实现结构，由于不同的实现结构需要满足不同的射频指标，这将会导致功率配置的限值无法准确上报，尤其当PC2支持2 PC2 PA+1LO和1x23dBm PA+1x26dBm PA+1LO的终端也可以上报支持TxD时。
本发明主要解决当高功率终端同时支持UL MIMO和带内连续的上行载波聚合时，如何区分不同的实现结构以便于应用相应的射频指标。
为此，提供了以下方案：
方法1：在多载波系统中引入新的信令指示终端支持的功率等级组合。例如IE Tx-architecture ENUMERATED{pc3+pc3,pc2+pc2,pc3+pc2,…}.
方法2：在多载波系统中引入新的信令指示终端支持的每条发射链路的功率等级，例如IE Tx1-powerClass ENUMERATED{pc1,pc1.5,pc2,pc3,pc4,pc5}and Tx2-powerClass ENUMERATED{pc1,pc1.5,pc2,pc3,pc4,pc5}
方法3：基于各频段在多载波系统中支持的功率等级，如ue-PowerClass-CA-r17ENUMERATED{pc1,pc1.5,pc2,pc3,pc4,pc5}，引入信令指示终端在该频段是否支持不同功率等级的发射链路diffpowerClass-tx ENUMERATED{supported}。
