一种波束确定方法及设备
相关申请的交叉引用
本申请要求在2020年07月27日提交中国专利局、申请号为202010734328.1、申请名称为“一种波束确定方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种波束确定方法及设备。
背景技术
在NR(New Radio，新空口)系统中，基站通过确定的波束的下行方向向用户终端发送下行数据，同时用户终端根据波束互易性通过上述波束的上行方向发送上行数据。
相关技术中，基站向用户终端发送多个信道状态信息参考信号(Channel State Information reference signals，简称CSI-RS)资源，用户终端对各CSI-RS资源进行波束扫描得到层1参考信号接收功率(Layer 1Reference Signal Received Power，简称L1-RSRP)，将L1-RSRP最大值和对应CSI-RS资源的信道状态信息参考信号资源指示符(CSI-RS Resource Indicator，简称CRI)发送至基站。基站根据接收到的CRI可以确定其对应的波束为最优波束，同时终端根据波束互易性确定该最优波束的上行方向。
为了避免终端对人体产生过大辐射，NR系统中规定了最大允许辐射(maximum permissible exposure，简称MPE)。当波束方向面向人体时，必须将通过此波束的发射的上行传输功率降低至MPE所允许的范围内。因此需要对此方向的上行传输进行功率回退，如果通过上述方案中确定的波束向面向人体时，通过该波束发送上行数据，就会造成传输性能的损失。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)本申请实施例中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。
(2)本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
(3)“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
(4)本申请实施例中，终端，是一种具有无线通信功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart  home)中的无线终端等；还可以是各种形式的UE，移动台(mobile station，MS)，终端设备(terminal device)。
(5)本申请实施例中，网络侧设备可以是基站，是一种为终端提供无线通信功能的设备，包括但不限于：5G中的gNB、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(BaseBand Unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。本申请中的基站还可以是未来可能出现的其他通信系统中为终端提供无线通信功能的设备。
在NR系统中，基站通过确定的波束的下行方向向用户终端发送下行数据，同时用户终端根据波束互易性通过上述波束的上行方向发送上行数据。基站向用户终端发送多个CSI-RS资源，用户终端对各CSI-RS资源进行波束扫描得到L1-RSRP，将L1-RSRP最大值和对应CSI-RS资源的CRI发送至基站。基站根据接收到的CRI可以确定其对应的波束为最优波束，同时终端根据波束互易性确定该最优波束的上行方向。
然而为了避免终端对人体产生过大辐射，NR系统中规定了MPE，当波束方向面向人体时，必须将通过此波束的发射的上行传输功率降低至MPE所允许的范围内。因此需要对此方向的上行传输进行功率回退，如果通过上述方案中确定的波束向面向人体时，通过该波束发送上行数据，就会造成传输性能的损失。
为了解决上述问题，本申请实施例提供了一种波束确定方法及设备。目标波束是基于参考信息确定的，参考信息是功率回退信息和/或根据功率回退信息得到的参考信号接收功率，因此目标波束的确定考虑了功率回退信息的影响，能够确定出上行传输性能比较好的波束，终端通过该波束发送上行数据，能够避免传输性能的损失。
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本 申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
如图1所示，为本申请实施例提供的一种波束确定的系统结构图，该系统中包括有网络侧设备10和终端20。

终端20，用于根据网络侧设备10的配置，向所述网络侧设备10发送参考信息，其中所述参考信息包括功率回退信息和/或参考信号接收功率，所述参考信号接收功率是基于功率回退信息得到的；所述终端20，还用于接收所述网络侧设备10发送的目标波束指示，以及基于所述目标波束指示中的目标波束进行信号的发送或接收，其中所述目标波束指示是所述网络侧设备10基于所述参考信息确定的。
本实施例中，终端根据网络侧设备的配置，向网络侧设备发送该配置对应的参考信息，其中发送的参考信息可以为多种，包括但不限于：至少一个功率回退信息、至少一个参考信号接收功率，或者同时有功率回退信息和参考信号接收功率。
另外，本实施例对发送的参考信息的数量不做具体限定，可根据实际应用场景进行选择。
上述实施例，目标波束是基于参考信息得到的，参考信息是功率回退信息和/或根据功率回退信息得到的参考信号接收功率，因此目标波束的确定考虑了功率回退信息的影响，能够确定出上行传输性能比较好的波束，终端通 过该波束发送上行数据，能够避免传输性能的损失。
在一些实施例中，网络侧设备向终端发送panel配置信息，终端基于所述panel配置信息确定接收CSI-RS资源的方式和/或接收所述CSI-RS资源的panel；
或者终端向网络侧设备发送其panel数目和/或panel标识信息。
本实施例中，终端可能有一个或者多个panel，根据上述panel配置信息，终端能够确定是否采用全部panel接收CSI-RS资源、采用哪些panel接收CSI-RS资源等信息。
终端向网络侧设备发送其panel数目和/或panel标识信息，网络侧设备能够得到该终端的panel相关信息。在一些具体的实施例中，所述panel配置信息包括以下信息中的至少一种：panel标识、panel数量以及是否采用单panel。
终端根据panel配置信息中panel标识，可以确定采用哪些panel接收CSI-RS资源；根据panel数量可以确定采用多少panel接收CSI-RS资源；根据是否采用单panel可以确定接收CSI-RS资源的方式。例如：
1)终端中有四个panel：panel1、panel2、panel3、panel4，panel配置信息包括：panel标识为panel1、panel2，不是采用单panel，终端基于该panel配置信息确定仅采用四个panel中的panel1和panel2接收CSI-RS资源，并且不是采用单panel的方式；
2)终端中有四个panel：panel1、panel2、panel3、panel4，panel配置信息包括：panel标识为panel1，采用单panel，终端基于该panel配置信息确定仅采用四个panel中的panel1接收CSI-RS资源，并且采用单panel的方式；
3)终端中有四个panel：panel1、panel2、panel3、panel4，panel配置信息包括：panel标识为panel1、panel2、panel3、panel4，不是采用单panel，终端基于该panel配置信息确定所有panel接收CSI-RS资源，并且不是采用单panel的方式。
可以理解，上述panel配置信息还可以包含其他与panel相关的信息，此处不再一一举例说明。
上述方法，终端根据panel配置信息，能够确定接收CSI-RS资源的方式，接收CSI-RS资源的面板，从而满足采用不同的接收CSI-RS资源的方式，采用不同接收面板接收CSI-RS资源的需求，更加灵活地接收CSI-RS资源，进而确定每个CSI-RS资源对应的L1-RSRP、功率回退信息和CRI。
在一些实施例中，如果上述参考信息包括所述功率回退信息，发送的功率回退信息可以为终端向网络侧设备发送的每个L1-RSRP或者每个CRI对应的功率回退值；也可以为终端向网络侧设备发送的每个L1-RSRP或者每个CRI对应的功率回退值中非零的功率回退值。
示例性的，终端对接收的各CSI-RS资源进行检测，得到对应的L1-RSRP，并判断是否将其发送，如果确定将其发送，那么将该L1-RSRP，以及对应的CSI-RS资源的功率回退信息和CRI发送至网络侧设备；或者在发送前判断该回退信息是否为零，如果为零仅将该L1-RSRP以及该CRI发送，如果不为零将该L1-RSRP、该回退信息以及该CRI发送。
上述方法，终端发送的功率回退信息可以为该终端向网络侧设备发送的每个L1-RSRP或者每个CRI对应的功率回退值，也可以是该对应的功率回退值中不为零的功率回退值，从而可以根据不同应用场景灵活地发送不同的功率回退信息。
本实施例对发送的L1-RSRP不做限定，例如：
1)选择每个面板测量得到的最大L1-RSRP发送；
2)选择大于第一预设阈值的L1-RSRP发送，第一预设阈值的具体数值可根据实际应用场景进行设定；
3)选择从大到小的顺序中，排在前N个的L1-RSRP发送，其中N为正整数，具体大小也可以根据实际应用场景进行设定。
上述几种发送的L1-RSRP仅是举例说明，不作为对本实施例的限定。
在一些实施例中，所述功率回退信息是基于MPE和/或所述终端的最大发送功率确定。
示例性的，通过传感器判断接收CSI-RS资源对应的波束是否面向人体， 如果不面向人体，那么该CSI-RS资源对应的功率回退值为零；如果面向人体需要进一步判断发送功率是否大于终端的最大发送功率，如果不大于则该CSI-RS资源对应的功率回退值为零，如果大于则该CSI-RS资源对应的功率回退值不为零。其中，可通过路径损耗计算相应的发送功率。另外具体功率回退值可以根据上述最大发送功率和上述发送功率之差得到，例如：
1)功率回退值Pb＝P0-Pmax，其中所述P0为上述发送功率，Pmax为上述最大发送功率；
2)功率回退值Pb＝(P0-Pmax)/delta，其中delta表示计算发送功率时对应于路径损耗的缩放因子。
其中，上述最大发送功率可以是根据MPE的要求确定的。
在一些实施例中，若所述参考信息包括参考信号接收功率，则所述网络侧设备的配置包括：所述网络侧设备发送的指示终端上报参考信号接收功率的信令。
可选地，所述终端基于所述功率回退信息对对应的L1-RSRP进行调整得到所述参考信号接收功率。

本实施例对发送的参考信号接收功率不做限定，例如：
1)选择大于第二预设阈值的参考信号接收功率，第二预设阈值的具体数值可根据实际应用场景进行设定；
2)选择从大到小的顺序中，排在前M个的参考信号接收功率，其中M为正整数，具体大小也可以根据实际应用场景进行设定。
上述几种发送的参考信号接收功率仅是举例说明，不作为对本实施例的限定。
在一些实施例中，上述参考信息仅包括功率回退信息，网络侧设备根据 接收的功率回退信息以及对应的L1-RSRP确定参考信号接收功率，选择确定的参考信号接收功率中最大的参考信号接收功率对应的CSI-RS资源的发送波束作为目标波束。
在另外一些实施例中，上述参考信息仅包括参考信号接收功率，网络侧设备根据接收的参考信号接收功率中最大的参考信号接收功率对应的CSI-RS资源的发送波束作为目标波束。
还有一些实施例中，上述参考信息同时包括功率回退信息和参考信号接收功率，网络侧设备先根据接收的功率回退信息以及对应的L1-RSRP确定参考信号接收功率，将确定的参考信号接收功率和接收的参考信号接收功率中最大的参考信号接收功率对应的CSI-RS资源的发送波束作为目标波束。
本申请通过下列实施例，对网络侧设备和终端如何确定目标波束进行说明。
实施例1，网络侧设备为终端配置S＝8个CSI-RS资源(分别表示为CSI-RS资源0～7)进行发送波束扫描，并配置终端上报CRI、L1-RSRP以及功率回退值。假设终端具有2个panel，分别表示为panel#0和panel#1。panel#0使用接收波束0进行接收，panel#1使用接收波束1进行接收。网络侧设备配置终端分别上报每个panel测量得到的最大RSRP的CSI-RS资源。
经过两个panel分别对8个CSI-RS资源进行RSRP测量后，终端确定panel#0接收到的最大RSRP为CSI-RS资源1的RSRP，表示为RSRP0，对应的CRI记为CRI_1；panel#1接收到的最大RSRP为CSI-RS资源3的RSRP，表示为RSRP1，对应的CRI记为CRI_3。同时，终端根据传感器确定panel#0朝向人体，而panel#1不朝向人体。因此需要判断panel#0的发送信号是否需要进行功率回退。终端可以通过RSRP0和RSRP1得到相应的路径损耗值。再根据计算出的路径损耗值计算相应的发送功率取值，分别表示为P0和P1。根据MPE的要求，确定终端的最大发送功率Pmax。若P0<＝Pmax，则没有超过最大发送功率，不需要进行功率回退，此时的功率回退值为0；若P0>Pmax,则超过最大发送功率，需要进行功率回退，以保证回退后的发送功率不大于 Pmax。一种功率回退值的计算可以根据NR中上行信号或信道的发送功率的计算方法确定。例如，功率回退值Pb可以计算为：
Pb＝P0-Pmax；
或者，Pb＝(P0-Pmax)/delta，其中delta表示所述发送功率计算时对应于路径损耗的缩放因子。
这样，根据以上的计算，终端的上报信息如表1所示。

表1为终端的上报信息
网络侧设备根据终端的上报信息确定上行panel和上行波束。一种确定方法为比较RSRP0-Pb0与RSRP1-Pb1的大小，例如：如果RSRP1-Pb1的取值较大，则网络侧设备确定使用panel#1的接收波束1作为上行信道或上行参考信号的发送波束，并向终端发送该波束的指示，终端基于该指示通过该波束进行后续传输。
实施例2，网络侧设备为终端配置S＝8个CSI-RS资源进行发送波束扫描，并配置终端上报4组CRI、L1-RSRP以及功率回退值。
假设终端具有2个panel，分别表示为panel#0和panel#1。panel#0使用接收波束0进行接收，panel#1使用接收波束1进行接收。经过两个panel分别对8个CSI-RS资源进行RSRP测量后，按照RSRP取值排序，最大的4个RSRP分别为：
panel#0接收的CSI-RS资源1，对应的CRI记为CRI_1；
panel#0接收的CSI-RS资源5，对应的CRI记为CRI_5；
panel#1接收的CSI-RS资源3，对应的CRI记为CRI_3；
panel#0接收的CSI-RS资源6，对应的CRI记为CRI_6；
终端分别确定这4个RSRP对应的功率回退值，功率回退值的确定方式与实施例1相同，这里不再赘述。这样，根据以上的计算，终端的上报信息如表2所示。后续网络侧设备确定上行波束的方法与实施例1相同，这里不再赘述。

第二组 CRI_5 RSRP1 Pb1

第四组 CRI_6 RSRP3 Pb3
表2为终端的上报信息
实施例3，基站为终端配置S＝8个CSI-RS资源(分别表示为CSI-RS资源0～7)进行发送波束扫描，并配置终端上报CRI、参考信号接收功率(记为MPE-RSRP)。假设终端具有2个panel，分别表示为panel#0和panel#1。panel#0使用接收波束0进行接收，panel#1使用接收波束1进行接收。基站配置终端分别上报每个panel测量得到的最大MPE-RSRP的CSI-RS资源。
经过两个panel分别对8个CSI-RS资源进行L1-RSRP测量后，终端针对每个L1-RSRP的测量结果均判断是否进行功率回退，并确定功率回退的取值。终端根据传感器确定panel#0朝向人体，而panel#1不朝向人体。因此，panel#1不需要进行功率回退，其测得的L1-RSRP值即为MPE-RSRP值。假设panel#1测得CSI-RS资源5的L1-RSRP最大，表示为L1-RSRP 1,5，对应的CRI记为CRI_5。对于panel#0测得的每个CSI-RS资源的L1-RSRP均需要判断其是否进行功率回退。确定功率回退的方法与实施例1相同，这里不再赘述。将panel#0测得的8个L1-RSRP分别表示为L1-RSRP 0,0，L1-RSRP 0,1，……，L1-RSRP 0,7，相应的每个CSI-RS资源对应的功率回退值表示为Pb0，Pb1，……， Pb7。则终端计算每个CSI-RS资源对应的MPE-RSRP，表示为MPE-RSRP0，MPE-RSRP1，……，MPE-RSRP7。其中，MPE-RSRPi＝L1-RSRP 0,i-Pbi，i＝0，1，…，7。假设MPE-RSRP3取值最大，对应的CRI记为CRI_3。终端选择每个panel中取值最大的MPE-RSRP进行上报，这样，终端的上报信息如表3所示。
Figure PCTCN2021107997-appb-000002
表3为终端的上报信息
网络侧设备根据终端的上报信息确定上行panel和上行波束。一种确定方法为比较MPE-RSRP3与L1-RSRP 1,5的大小，例如：如果MPE-RSRP3的取值较大，则基站确定使用panel#0的接收波束0作为上行信道或上行参考信号的发送波束，并向终端发送该波束的指示，终端基于该指示通过该波束进行后续传输；如果L1-RSRP 1,5的取值较大，则基站确定使用panel#1的接收波束1作为上行信道或上行参考信号的发送波束，并向终端发送该波束的指示，终端基于该指示通过该波束进行后续传输。在另外一些实施例中，网络侧设备10，用于向终端20发送panel配置信息。
终端20，用于基于所述panel配置信息中的发送SRS资源的方式和/或发送所述SRS资源的面板，通过根据功率回退得到的发送功率发送所述SRS资源；所述终端20，还用于基于所述确定的发送方式和/或面板，通过根据功率回退得到的发送功率向所述网络侧设备10发送所述SRS资源。
所述网络侧设备10，还用于根据各SRS资源的接收功率确定目标波束指示，并向所述终端20发送所述目标波束指示，以使所述终端20基于所述目标波束指示中的目标波束进行信号的发送或接收。
本实施例中，终端可能有一个或者多个panel，根据上述panel配置信息，终端能够确定是否采用全部panel发送SRS资源、采用哪些panel发送SRS资源等信息。
上述方法，终端通过panel配置信息可以确定发送SRS资源的方式和/或发送SRS资源的面板，进而可采用确定出的方式和/或面板，通过根据功率回退得到的发送功率向网络侧设备发送SRS资源，也就是说发送的SRS资源是考虑了功率回退的影响，因此网络侧设备根据接收各SRS资源的接收功率确定的是功率回退的影响下的目标波束，终端通过该目标波束发送上行数据，能够避免传输性能的损失。
在一些具体的实施例中，所述panel配置信息包括以下信息中的至少一种：panel标识、panel数量、是否采用单panel以及至少一个SRS资源集合。
终端根据panel配置信息中panel标识，可以确定采用哪些panel发送SRS资源；根据panel数量可以确定采用多少panel发送SRS资源；根据是否采用单panel可以确定发送SRS资源的方式，根据SRS资源集合，可以自行分配SRS资源集合与panel之间的映射关系。
可以理解，上述panel配置信息还可以包含其他与panel相关的信息，此处不再一一举例说明。
在一些实施例中，每个所述SRS资源集合与所述终端的一个panel相关联。
本申请通过下列实施例，对网络侧设备和终端如何确定目标波束进行说明。
实施例4，网络侧设备配置终端传输SRS，进行上行波束扫描。同时系统预定义1比特信令信息，指示终端采用单panel进行SRS发送，还是采用全部panel进行SRS发送。假设网络侧设备配置终端发送S＝8个SRS资源，同时指示终端采用全部panel发送。假设终端具有M＝4个panel，则终端可以自行分配8个SRS资源与4个panel之间的映射关系。例如：SRS0和SRS1由panel-0发送，SRS2和SRS3由panel-1发送，SRS4和SRS5由panel-2发送，SRS6和SRS7由panel-3发送。在进行SRS发送功率计算时，终端将确定每个panel是否朝向人体，需要进行功率回退。每个SRS资源使用考虑了功率回退后的发送功率进行传输。
网络侧设备对接收的每个SRS资源进行测量，选择其中接收功率最大的SRS资源，将此SRS资源的方向作为后续传输物理上行共享信道的波束方向。
