Figure PCTCN2019096914-appb-000001
多波束系统
NR/5G的多波束(Multi-beam)系统在下行链路中把发射功率集中在一个较窄的波束(beam)来覆盖小区中的部分区域,从而达到增强整个系统的覆盖范围。
·传统网络部署(例如3G,4G/LTE)使用一个波束(在传统系统中,不需要额外提波束这个概念,因为只有一个波束)来覆盖整个小区。例如图2-1中,网络使用一个相对宽的波束覆盖整个小区,可以同时为小区中的UE服务。NR中使用相对较窄的波束,因此可以把能量集中,从而使得离小区较远的UE也可以获得良好的接收性能。
·Multi-beam系统通过时间上的波束扫描(beam sweeping)来实现覆盖整个小区的效果,即不同时刻使用不同的波束来覆盖不同的区域。例如图2-2的示意中,多波束系统在不同时刻使用4个不同的波束分别覆盖不同的区域,小区中的UE只有当某个时刻某个波束正好覆盖到整个区域,其才能和网络进行通信,例如在时刻T3系统使用波束3能够覆盖UE3和UE4。
以上方案描述了下行采用多个发送波束(transmit beam)的情况。同样,UE也可以使用多个发送波束进行上传传输,原理类似。
需要说明的是,不同的波束通过其上面承载的不同信号或对应的参考信号资源来进行识别或者指示,具体地:
·可以通过同步信号块(Synchronization Signal/PBCH Block,SSB)来指示对应的上行或下行发送波束,这里的SSB是指SS/PBCH block,例如不同的下行波束上传输不同的同步信号块。
·可以通过信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)/CSI-RS资源来指示对应的上行或下行发送波束,例如不同的下行波束上传输不同的CSI-RS信号资源对应的信号。
·可以通过信道探测参考信号(Sounding Reference Signal,SRS)/SRS信号资源来指示对应的上行或下行发送波束,例如不同的波束上传输不同的SRS资源对应的信号。
·当在UE侧存在波束对应性(beam correspondence)时(例如,如果接收波束X是接收下行信号的较佳/最佳选择,UE根据接收波束X推断出其对应的发射波束Y是较佳/最佳的上行发送波束),如果网络指示某个下行发送波束的对应下行信号为A,则UE能够根据接收信号A对应的接收波束B知道其对应的发送波束C。在这种情况下,系统中指示UE的上行发送波束C,往往可以直接指示下行信号A来间接的指示发送波束C。
·上行传输波束,也可以叫做空间滤波器(spatial filter,spatial domain filter)。
因此可以基于上行或下行信号来和某个/某些波束对应。

网络确定UE上行发送波束的方法
如果UE存在多个上行发送波束时,网络确定UE使用哪个上行发送波束,可以有以下一些方法。
·方式1:网络配置多个SRS资源,让UE使用不同的上行发送波束进行对应的SRS传输(不同的上行发送波束发送不同的SRS资源对应的信号)。网络通过测量SRS信号,可以知道这些上行发送波束对应的链路质量。
·方式2:UE侧存在波束对应性的情况下,网络根据这一特性,认为UE根据其对应的较佳的下行发送波束,可以知道其对应的接收波束,进一步根据波束对应性知道此UE对应的较佳的上行发送波束。即网络通过指示一个下行参考信号资源,UE根据所述指示可以确定对应的上行发送波束(或者称为空间滤波器)。
对于方式1,网络可以配置周期性SRS(Periodic SRS,P-SRS)、半持续SRS(Semi-persistent SRS,SP-SRS)、非周期SRS(Aperiodic SRS,AP-SRS)让UE进行传输来实现。
对于方式2,网络配置UE根据对某些下行信号(SSB,CSI-RS resource对应的信号)进行测量,并且按照一定规则进行上报(reporting),网络根据UE上报(可选的,包含其他一些因素,例如不同波束上业务的负载)确定针对UE哪个或哪些下行发送波束较好,然后通过指示下行参考信号资源来通知UE使用对应的上行发送波束。

网络对UE上行发送波束的指示
网络指示UE使用哪个上行发送波束传输时,可以通过指示下列对应的参考信号资源的标识来间接地指示对应的上行发送波束:
·SRS资源指示标识(SRS resource indicator,SRI);
可选的,有的信令中包含SRS资源所在的上行BWP标识(BWP ID)对应的指示信息。
·同步信号块标识(SSB index);
·CSI-RS资源标识(CSI-RS resource indicator)。
对于物理上行共享信道(Physical Uplink Shared Channel,PUSCH),波束可以通过以下方式确定:
·动态调度的PUSCH
如果网络只配置了一个对应的SRS资源,则UE根据网络配置信息(例如对应的RRC信令)确定使用哪个上行发送波束。
如果网络配置了多个对应的SRS资源,则UE根据DCI指示信息所指示的SRS资源确定使用哪个上行发送波束。
·半持续调度的PUSCH
如果RRC参数(RRC IE)configuredGrantConfig中包含参数rrc-ConfiguredUplinkGrant,UE根据RRC参数中指示的SRS资源标识确定使用哪个上行发送波束。
如果RRC参数(RRC IE)configuredGrantConfig中不包含参数rrc-ConfiguredUplinkGrant,UE根据DCI指示信息所指示的SRS资源确定使用哪个上行发送波束。
对于SRS传输,网络针对SRS资源配置空间关系信息(SRS-SpatialRelationInfo),SRS-SpatialRelationInfo的RRC IE参见如下表1所示,其中,SRS-SpatialRelationInfo包含以下至少一种信息:
I)SRS资源指示标识;可选的,还包含SRS资源所在的上行BWP标识(BWP ID)对应的指示信息;
II)同步信号块标识;
III)CSI-RS资源标识。

对于物理上行控制信道(Physical Uplink Control Channel,PUCCH)传输,网络针对PUCCH配置空间关系信息(PUCCH-SpatialRelationInfo),PUCCH-SpatialRelationInfo的RRC IE参见如下表2所示,其中,PUCCH-SpatialRelationInfo包含以下至少一种信息:
I)SRS资源指示标识;可选的,还包含SRS资源所在的上行BWP标识(BWP ID)对应的指示信息;
II)同步信号块标识;
III)CSI-RS资源标识。

如果针对PUCCH,网络配置了一个PUCCH-SpatialRelationInfo,则所有的PUCCH资源都根据网络配置的这一信息来确定使用哪个上行发送波束。如果针对PUCCH,网络配置了多个PUCCH-SpatialRelationInfo,则每个PUCCH资源都根据网络进一步的指示信息或配置信息或激活信息(例如MAC CE)所指示的空间关系信息来确定使用哪个上行发送波束。

MPE问题
为了人体安全考虑,UE的发射功率需要控制在规定的安全范围内。如果UE侧采用多个发送波束进行上行传输,可以采用相对较窄的波束把能量集中进行传输。当UE靠近人体,有可能会发生发射功率或有效全向辐射功率(Effective Isotropic Radiated Power,EIRP)超过安全限值,即出现MPE问题。一种处理方法是当发生这种情况时,UE进行功率回退,即降低发射功率来保证人体安全。在这种处理中,如果不区分不同的上行发送波束是否对准人体,即为了安全起见,假设每个上行发送波束都可能对着人体,来进行功率回退,波束管理(beam management)机制可以有效地工作。
但是,在实际应用场景中,由于上行发送波束带有一定的方向性,如果一个波束对准人体,如果发射功率或EIRP超过规定的安全值,则需要进行功率回退;如果一个波束没有对准人体,则可以不用考虑功率回退,或者可以减少功率回退的取值。普遍的终端会带有一些传感器,通过传感器可以判断出每个波束或者某些波束是否对准人体。
如果针对不同的波束或者不同的波束组是否对准人体,采用对应的功率回退,则波束管理机制有可能会导致系统性能下降,以下举例说明。
A)按照前述方式1,如果网络配置了非周期SRS,并且基于非周期SRS选定了上行发送波束,并通知UE使用选定的上行发送波束进行上行传输。如果UE进行了移动或者旋转,当前工作的上行发送波束对准人体,需要进行功率回退时,会导致当前上行发送波束链路实际传输功率低,从而存在另一个上行发射波束实际传输效果更好的情况,则当前上行发送波束不是一个最优的选择。这时候需要一定的信息来协助或者建议网络重新进行波束选择。
B)按照前述方式2,网络根据最优或较优的下行发送波束来确定UE的上行发送波束,如果这一上行发送波束对准人体,需要进行功率回退时,会导致当前上行发送波束链路实际传输功率低,从而存在另一个上行发射波束实际传输效果更好的情况,则当前上行发送波束不是一个最优的选择。这时候需要一定的信息来协助或者建议网络重新进行波束选择。
例如图2-3所示,原先网络选择波束1的上行发送波束是最佳的,但是由于正好对准人体的原因,导致UE需要针对波束1进行功率回退。此时如果采用波束2会更好(因为波束2没有对准人体,因此可以不进行功率回退,或者功率回退的值较小)。
针对上述问题,目前还没有相应的解决方案,为此提出了本申请实施例的以下技术方案。本申请实施例的技术方案明确了终端的上报信息,通过上报信息来协助或者建议网络进行相应的波束管理流程(例如波束选择,波束指示)。

这里,通过物理层信道发送上报信息,上报时延小,网络可以更快地获得上报信息,提高网络性能和用户体验。
方式二:终端通过高层信令道向网络设备发送上报信息。
进一步,在一可选实施方式中,所述高层信令可以是媒体接入控制控制单元(Media Access Control Control Element,MAC CE)信令。

这里,优先级信息也可以称为排序指示信息,比如排序的序号越小,代表优先级越高,或者,排序的序号越小,代表优先级越低。通过在每个第一信息中携带对应的参考信号资源的优先级信息,可以使得优先级的指示更加灵活。
◆在一可选实施方式中,所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的第一参数。

举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的最大发送功率(P_CMAX),其中,P_CMAX为配置的最大发送功率(configured maximum output power)。这里,通过P_CMAX来隐式地表示功率回退的影响,从而可以避免在上报信息中显示地携带功率回退信息,避免披露终端的具体实现。进一步,所述P_CMAX是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源X,则这个第一信息携带的P_CMAX也是根据参考信号资源X对应的参数确定,这里的P_CMAX就是beam-specific P_CMAX。
举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的功率余量(power headroom)。这里,通过功率余量来隐式地表示功率回退的影响,从而可以避免在上报信息中显示地携带功率回退信息,避免披露终端的具体实现。进一步,所述功率余量是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源Y,则这个第一信息携带的功率余量也是根据参考信号资源Y对应的参数确定,这里的功率余量就是beam-specific power headroom。进一步,可选地,所述第一信息中携带的所述功率余量的类型可以是类型1(Type 1),或者是类型2(Type 2),其中,Type 1是针对PUSCH的功率余量,Type 2 是针对SRS的功率余量。
举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的功率回退信息。这里,在上报信息中显示地表示功率回退的影响,可以直接表示出上行发送功率受到的影响。进一步,所述功率回退信息是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源Z,则这个第一信息携带的功率回退信息也是根据参考信号资源Z对应的参数确定,这里的功率回退就是beam-specific功率回退。

进一步,可选地,所述上报信息中包括至少一个第一指示信息,所述至少一个第一指示信息在所述上报信息中的位置用于指示所述至少一个第一指示信息所指示的至少一个参考信号资源的优先级。
这里,在所述上报信息中,靠前的第一指示信息所指示的参考信号资源的优先级高于靠后的第一指示信息所指示的参考信号资源的优先级,或者,靠前的第一指示信息所指示的参考信号资源的优先级低于靠后的第一指示信息所指示的参考信号资源的优先级。本申请实施例的技术方案中,终端设备通过第一指示信息的位置隐式地推荐了优先级信息给网络设备,协助网络设备做出更好的波束判断。
◆在一可选实施方式中,所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的第一参数。
进一步,可选地,所述第一信息中携带的第一参数根据所述第一信息对应的参考信号资源关联的参数确定。
上述方案中,所述第一参数包括以下至少之一:最大发送功率、功率余量、功率回退信息。
举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的最大发送功率(P_CMAX),其中,P_CMAX为配置的最大发送功率(configured maximum output power)。这里,通过P_CMAX来隐式地表示功率回退的影响,从而可以避免在上报信息中显示地携带功率回退信息,避免披露终端的具体实现。进一步,所述P_CMAX是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源X,则这个第一信息携带的P_CMAX也是根据参考信号资源X对应的参数确定,这里的P_CMAX就是beam-specific P_CMAX。
举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的功率余量(power headroom)。这里,通过功率余量来隐式地表示功率回退的影响,从而可以避免在上报信息中显示地携带功率回退信息,避免披露终端的具体实现。进一步,所述功率余量是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源Y,则这个第一信息携带的功率余量也是根据参考信号资源Y对应的参数确定,这里的功率余量就是beam-specific power headroom。进一步,可选地,所述第一信息中携带的所述功率余量的类型可以是类型1(Type 1),或者是类型2(Type 2),其中,Type 1是针对PUSCH的功率余量,Type 2是针对SRS的功率余量。
举个例子:所述至少一个第一信息中的每个第一信息中携带该第一信息对应的参考信号资源的功率回退信息。这里,在上报信息中显示地表示功率回退的影响,可以直接表示出上行发送功率受到的影响。进一步,所述功率回退信息是根据对应的参考信息资源关联的参数确定,例如某个第一信息对应参考信号资源Z,则这个第一信息携带的功率回退信息也是根据参考信号资源Z对应的参数确定。,这里的功率回退就是beam-specific功率回退
上述方案中,可选的,所述上报信息中包括至少一个第一参数,所述至少一个第一参数在所述上报信息中的位置用于指示所述至少一个第一信息对应的至少一个参考信号资源的优先级。

方式一:所述终端设备传输上行信号的情况下,所述最大发送功率、功率余量、功率回退信息中的至少之一,根据所述终端设备传输的上行信号(包括上行数据和上行参考信号等)进行确 定。
这里,所述终端设备传输上行信号是指所述终端设备在某个参考信号资源对应的上行发送波束上传输上行信号。举个例子:如果某个上行发送波束上有实际信号传输(例如PUSCH或SRS的传输),则终端设备按照实际信号传输计算所述最大发送功率、功率余量、功率回退信息中的至少之一。
方式二:所述终端设备未传输上行信号的情况下,所述最大发送功率、功率余量、功率回退信息中的至少之一,根据指定的参数进行确定。
这里,所述终端设备未传输上行信号是指所述终端设备在某个参考信号资源对应的上行发送波束上未传输上行信号。举个例子:如果某个上行发送波束上没有对应的实际信号传输,则终端设备根据以下指定的参数计算所述最大发送功率、功率余量、功率回退信息中的至少之一。
需要说明的是,所述最大发送功率、功率余量、功率回退信息的计算需要使用传输带宽、调制方式等参数,所以计算时必须明确使参数的取值,避免网络侧与终端侧理解的模糊性。所述指定的参数包括以下至少之一:
所述参考信号资源对应的用于路损测量的参考信号;
所述参考信号资源对应的路损系数;
根据所述参考信号资源对应的闭环功控标识确定的功控指令;

上述方案中,第一闭环功控系数例如为0。
上述方案中,第一功率参数例如为P O_NOMINAL_PUSCH,f,c
上述方案中,第二功率参数例如为P O_SRS,b,f,c
进一步,在一个例子中,可以基于MPR=0dB,A-MPR=0dB,P-MPR=0dB,ΔT C=0dB,来计算最大发送功率,其中,P-MPR代表最大的输出功率回退(allowed maximum output power reduction),MPR代表和调制方式对应的最大功率回退(maximum power reduction),A-MPR代表额外最大功率回退(additional maximum power reduction),ΔT C代表额外的功率放松。
进一步,在一个例子中,根据参考信号资源对应的P-MPR来计算最大发送功率或者功率余量。
进一步,可选地,所述最大发送功率、功率余量、功率回退信息中的至少之一,还根据参考带宽确定;其中,所述参考带宽是预设的(或者说协议规定的)或者是网络设备配置的或者是最近一次上行传输的传输带宽。

举个例子:所述参考带宽由网络设备通过RRC信令配置。
举个例子:所述参考带宽是所述终端设备在同一BWP或者同一个小区上的最近一次上行传输的传输带宽。
进一步,可选地,所述终端设备在确定所述最大发送功率、功率余量、功率回退信息中的至少之一时,忽略与带宽相关的计算项。
进一步,可选地,所述最大发送功率、功率余量、功率回退信息中的至少之一,还根据参考调制方式确定;其中,所述参考调制方式是预设的(或者说协议规定的)或者是网络设备配置的或者是最近一次上行传输的调制方式。
举个例子:所述参考调制方式由网络设备通过RRC信令配置。
举个例子:所述参考调制方式是同一BWP上的最近一次上行传输的调制方式。
进一步,可选地,所述终端设备在确定所述最大发送功率、功率余量、功率回退信息中的至少之一时,忽略与调制方式相关的计算项。
需要说明的是,上述第一信息中携带的内容可以进行任意组合,形成不同的具体方案。
对于上述方案3描述的上报信息,终端设备可以采用MAC CE来传输上报信息。进一步,可选地,所述上报信息和功率余量报告(Power Headroom Report,PHR)通过同一消息进行传输。这里,终端设备在进行PHR上报时,把所述上报信息和PHR一起上报,从而可以利用PHR的上报触发机制,降低终端实现复杂度。
在一可选实施方式中,所述上报信息携带在第一MAC CE中,所述PHR携带在第二MAC CE中;或者,所述上报信息和所述PHR携带在第一MAC CE中。
举个例子:携带PHR的MAC CE为PHR MAC CE,所述上报信息可以携带PHR MAC CE中,也可以携带在其他MAC CE中。
进一步,所述MAC CE至少包括第一位图,所述第一位图中的每个比特位与一个参考信号资源对应,所述比特位的取值用于表示所述MAC CE是否携带了该比特位对应的参考信号资源对应的第一参数(如最大发送功率、功率余量、功率回退信息)。
需要说明的是,上述各项可选的方案可以进行任意组合,形成不同的MAC CE的方案。
假设终端设备根据一组CSI-RS资源(假设一共N个CSI-RS资源,记为CSI-RS-1,…,CSI-RS-N)确定上报信息,所述一组CSI-RS资源通过第一配置信息进行配置,其中,上报信息对应一组CSI-RS资源中的M个CSI-RS资源,M为小于等于N的正整数。一些上报信息的可选例子如下,需要指出的是,以下例子也可以适用于SSB或SRS资源。
示例十二:在MAC CE中,一个第一信息携带一个CSI-RS资源(一个CSI-RS资源对应一个波束)对应的功率余量。当MAC CE含有多个功率余量时,所述多个功率余量的排列顺序(排列顺序可以代表优先级顺序)可以有以下几种选项:
1)根据功率余量对应的参考信号资源在RRC配置信令中的位置。
2)根据功率余量对应的参考信号资源的标识的大小确定(例如可以根据参考信号资源的标识从大到小确定,或者从小到大确定)。
3)根据功率余量对应的参考信号资源的类型确定。例如:SSB>SRS>CSI-RS,SSB>CSI-RS>SRS,SRS>SSB>CSI-RS,SRS>CSI-RS>SSB,CSI-RS>SRS>SSB,CSI-RS>SSB>SRS),其中,“>”代表优先级高于。
需要说明的是,上述3)可以和1)或2)进行结合,即优先使用3)确定排列顺序,然后在同一类型中使用1)或2)2进一步确定排列顺序。
图4-1是一个MAC CE中部分内容的示意图,其中图中一行表示一个字节(byte),即8比特。在图4-1中,没有表示预留比特(Reserved bit),不局限于此,在一行中可能会有部分预留比特,剩余比特用于表示功率余量。一个例子是,1bit为预留比特,7bit表示功率余量。后续示意图中都不在明确预留比特,但是本申请实施例包含部分比特预留的方案。
为了压缩上报信息的开销,可以在一个byte中表示多个功率余量,如图4-2所示。
本示例中,多个功率余量可以通过对PHR MAC CE进行修改或者扩展相关域来进行携带,或者通过一个新的MAC CE来携带。
需要说明的是,上述示例十二中只描述了功率余量的情况,同样可以类似扩展到功率回退、P_CMAX的情况。
示例十三:在MAC CE中,一个第一信息携带一个参考信号资源对应的第一指示信息以及对应的功率余量。
图4-3是MAC CE中部分内容的示意图,在图4-3中没有表示预留比特,不局限于此,图4-3中的每行都有可能有预留比特。
为了压缩上报的开销,可以在一个byte中表示参考信号资源指示信息以及对应的功率余量,如图4-4所示。
本示例中,多个功率余量可以通过对PHR MAC CE进行修改或者扩展相关域来进行携带,或者通过一个新的MAC CE来携带。
需要说明的是,上述示例十三中只描述了功率余量的情况,同样可以类似扩展到功率回退、P_CMAX的情况。
示例十四:在MAC CE中,一个第一信息携带一个参考信号资源对应的功率余量,其中,一个参考信号资源对应一个波束。此外,通过位图(bitmap)来指示MAC CE中携带了哪些参考信号资源对应的功率余量。例如M=2,则通过2bit的bitmap来指示MAC CE中携带了哪些参考信号资源对应的功率余量。其中,在一个例子中,bitmap中的比特位的取值为1表示携带,取值为0表示不携带。
图4-5是一个MAC CE中部分内容的示意图,在图4-5中没有表示预留比特,不局限于此,图4-5中的每行都有可能有预留比特。同时假设bitmap在一个byte的前两位,实际设计时bitmap也可以在其他位置。
本示例中,多个功率余量可以通过对PHR MAC CE进行修改或者扩展相关域来进行携带, 或者通过一个新的MAC CE来携带。如果是利用PHR MAC CE来携带多个功率余量,可以利用PHR MAC CE里面的预留比特来表示bitmap,从而可以进一步节约开销。
需要说明的是,上述示例十四中只描述了功率余量的情况,同样可以类似扩展到功率回退、P_CMAX的情况。
在上面方案的基础上,终端设备和网络设备可以有如下处理操作。
终端设备的处理操作:终端设备根据情况(例如是否靠近人体等因素)决定是否需要进行功率回退,如果进行功率回退,确定功率回退的取值,并进行发射功率相关的操作。
网络设备的处理操作:网络设备接收到上报信息后,可以有不同的处理,例如:如果上报信息中包含多个参考信号资源的标识(对应波束的标识),以及参考信号资源对应的第一参数(如功率回退信息、P_CMAX、功率余量),则网络设备有可能直接从上报信息中确定使用哪个上行波束,后续通知终端设备使用选定的上行波束进行上行传输。
