超宽带宽的高频段通信(即毫米波通信)成为未来移动通信发展的重要方向,吸引了全球的学术界和产业界的目光。在当前频谱资源日益拥塞和物联网大量接入的情况下,毫米波通信的优势变得越来越有吸引力,在很多标准组织,例如电气和电子工程师协会(IEEE,Institute of Electrical and Electronics Engineers)、第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)都开始展开相应的标准化工作。例如,在3GPP标准组,高频段通信凭借着大带宽的显著优势将会成为第五代移动通信技术(5G,5th Generation)新一代无线接入技术(New RAT,New Radio Access Technology)的重要创新点。
目前基站可以存在多个天线面板,而每个天线面板可以产生多个波束,对于用户设备(UE,User Equipment)而言也有类似的情况,相关5G通信系统中,在同一时刻下,模拟波束是假定不能发生碰撞的,但是,随着UE和集中的天线面板的增加,不同信道特征假设下的信道和参考信号在不同的天线面板下是可以同时发送的,这样就会造成信道或参考信号发生碰撞。目前尚未有有效的方法解决多天线面板的信道或参考信号的信道特征假设发生碰撞时信道或参考信号的接收问题。

具体实施方式
下文中将结合附图对本发明实施例进行详细说明。需要说明的是,在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
图1为本发明实施例混合预编码(混合模拟数字波束赋型)收发机的结构示意图。如图1所示,发送端和接收端分别配置多个天线阵列单元(即天线面板(antenna panel),或天线单元),每个天线面板包含多个收发天线,并与多个射频链路(即收发单元(Transmit Receive Unit,TXRU))相互连接(不排斥部分连接场景),天线面板与TXRU之间拥有数字键控移相器。
高频段系统通过为各个天线面板上的信号加载不同相移量的办法,实现模拟端的波束赋形(Beamforming)。具体而言,在发送端,一个射频链路存在多条射频信号流,每条射频信号流通过数字键控移相器加载天线权重矢量(AWV, Antenna Weight Vector),将加载AWV后的射频信号通过合并器加权合并成单一射频信号流,将单一射频信号流从多天线面板发送到高频段物理传播信道;在接收端,将由多天线面板所接收到的射频信号流通过分离器进行分离得到分离信号,分离信号通过数字键控移相器乘以接收端AWV,新获得的信号通过合并器被加权合并成单一射频信号流,经过接收端射频解调,接收机最终获得多条接收射频信号流,并被数字基带采样和接收。因此,混合预编码(混合模拟数字波束赋型)收发机可以同时产生指向多个方向的射频波束。
同时,发送端和接收端可能有多个天线面板,为了更好的支持空分复用和减少硬件实现复杂度。因此,每个天线面板下,有效波束的数目是和实际可以支持最大的发送波束(beam)的数目是不对称的,即每个时刻可以发送的beam数目,即TXRU数目,是远小于可选波束的数目。

例如,从第一通信节点的角度看,向第二通信节点发送自身所支持的面向多天线面板或多仪表板(panel)的能力信息,而冲突碰撞的判定准则需要是基于UE天线面板组(UAG,per UE antenna group),也就是说,当调用了相同UAG并且不同发射波束(Tx beam)时,定义为碰撞;当调用了不同的UAG并且相同或不同的Tx beam时,不定义为碰撞。

在具体实现过程中,当三个或三个以上信息元素满足预设条件时,可以采用循环迭代的方式来实现,也就是说,当确定信息元素满足预设条件时,确定最低优先级的信息元素的接收方式;继续判断信息元素是否满足预设条件,当确定信息元素满足预设条件时,确定次低优先级的信息元素的接收方式;继续判断信息元素是否满足预设条件,当确定信息元素满足预设条件时,确定第3低优先级的信息元素的接收方式;以此类推,直到信息元素不满足预设条件。

下面通过具体例子对上述实施例的信息元素的传输方法进行说明,所列举的例子并不用于限定本发明实施例的保护范围。
示例1
假定UE端支持分组上报(group-based reporting),即分组上报CSI reporting,在CSI报告中,对上报的RS ID进行分组上报,其中最多两个参考信号可以被UE同时接收。基于UE所支持的面向多天线面板的能力信息以及基站所支持的面向多天线面板的能力信息,基站向UE配置T1信息:UE需要同时接收的下行信息元素的不同信道特征假设的数目T1=2。
图3为本发明实施例的示例1的物理下行共享信道(PDSCH,Physical Downlink Shared Channel)的信道特征假设发生碰撞的示意图。如图3所示,UE接收多时隙(multi-slot)PDSCH,例如时隙聚合(slot-aggregation)PDSCH,PDSCH所关联的空间参数下的DL RS为{c-2,c-5},又称为波束为c-2和c-5。
CORESET-2调度了一个i-PDSCH,这里i-PDSCH表示PDSCH的调度偏置小于门限k。即,UE端在接收i-PDSCH时,并不能意识到这里存在一个i-PDSCH, 即只能使用假定的波束进行接收。根据准则,i-PDSCH需要服从CORESET-3的信道特征假设,即波束为c-6。
根据T1=2的假定,Multi-slot PDSCH和i-PDSCH的不同空间参数的数目为3,大于T1,Multi-slot PDSCH和i-PDSCH的信道特征假设发生碰撞,因此低优先级的i-PDSCH的信道特征假设被特定信道特征假设覆盖,即被高优先级的Multi-slot PDSCH的信道特征假设覆盖。因此,i-PDSCH的信道特征假设被重写成{c-2,c-5}。
图4为本发明实施例的示例1的PDSCH的信道特征假设不发生碰撞的示意图。如图4所示,UE接收multi-PDSCH,multi-PDSCH所关联的空间参数下的DL RS为{c-2},而CORESET-2调度了一个i-PDSCH,该i-PDSCH的默认波束,即所关联的空间参数DL RS为{c-6,c-2}。
从整体而言,multi-slot PDSCH和i-PDSCH一并关联的波束为{c-6,c-2},并不大于T1=2,multi-slot PDSCH和i-PDSCH的信道特征假设不发生碰撞。根据准则,在multi-slot PDSCH与i-PDSCH重合的部分,需要按照联合的空间参数{c-6,c-2}进行接收;或者,UE端根据multi-slot PDSCH={c-2}和i-PDSCH={c-6,c-2}来自行决定multi-slot PDSCH和i-PDSCH的接收波束,即multi-slot PDSCH={c-2}和i-PDSCH={c-6,c-2}都是有效的。
示例2
在UE上报自身所支持的面向多天线面板或多panel的能力信息时,UE的第A类分组的数目R1=2,其中第A类分组的特征为不同分组关联的信息元素可以被同时接收,而同一分组关联的具有不同信道特征假设的信息元素不能被同时接收。因此,对于UE构成了两个UAG索引,分别称为UAG-a和UAG-b。
图5为本发明实施例的示例2的PDSCH与PDCCH的信道特征假设发生碰撞的示意图。如图5所示,对于控制信道PDCCH,CORESET-2的空间参数下的DL RS配置为{[c-1,UAG-a]},CORESET-3的空间参数下的DL RS配置为{[c-6,UAG-b]};而Multi-slot PDSCH包括两个slot,空间参数下的DL RS分别为{[c-2,UAG-a];[c-5,UAG-b]};并且,multi-slot PDSCH的优先级高于PDCCH的优先级。
准则1:低优先级的信道的空间参数,需要被覆盖成高优先级的信道的与低 优先级具有相同UAG索引下的空间参数。因此,对于CORESET-2,UAG-a发生了碰撞,因此,CORESET-2下的空间参数仅面向所关联的同一UAG下的空间参数信息进行覆盖。即从UE的角度看,CORESET-2的空间参数为{[c-2,UAG-a]}。同样道理,CORESET-3的空间参数为{[c-5,UAG-b]}。
准则2:低优先级的信道不被监控。因此,控制信道CORESET-2和CORESET-3将不会被UE端监控。
示例3
在UE上报自身所支持的面向多天线面板或多panel的能力信息时,UE的第A类分组的数目R1=2,UE的第A类分组下的第B分组的数目R2=2。其中,第A类分组的特征为不同分组关联的信息元素可以被同时接收,而同一分组包括E个第B类分组;第B类分组的特征为不同分组关联的信息可以被同时接收,而同一分组关联的具有不同信道特征假设的信息元素不能被同时接收。
图6为本发明实施例的示例3的PDSCH与PDCCH信道特征假设发生碰撞的示意图。对于控制信道PDCCH,CORESET-2的空间参数下的DL RS配置为{[c-1,UAG-a]},CORESET-3的空间参数下的DL RS配置为{[c-1,UAG-b],[c-6,UAG-b]};同时,包括两个PDSCH的传输,其中PDSCH-1的空间参数下的DL RS为{[c-2,UAG-a],[c-5,UAG-b]},而PDSCH-2的空间参数下的DL RS也为{[c-2,UAG-a],[c-5,UAG-b]}。PDSCH的优先级高于PDCCH的优先级。
-CORESET-2/PDSCH-1:由于一个UAG下可以同时支持两个第B类分组,因此,从UE的角度看,不认为CORESET-2与PDSCH-1发生了碰撞。换言之,CORESET-2和PDSCH-1都正常接收,而具体接收波束,由UE端自行决定;
-CORESET-3/PDSCH-2:对于UAG-b下,有Y1=3个不同的空间参数,超过了R2=2的上限,因此,低优先级的CORESET-3所关联的UAG-b的空间参数被PDSCH所关联的UAG-b的空间参数覆盖。即CORESET-3的空间参数下的DL RS修改成{[c-5,UAG-b]}。进一步的,CORESET-3的整体QCL假设或者TCI状态修改成PDSCH的关联UAG-b的TCI状态。
示例4
在UE上报自身所支持的面向多天线面板或多panel的能力信息时,同时接收下行参考信号资源和/或下行信道的数目R1=2,基站端配置基站的第A类分组数 目T1=2,而基站的第A类分组下第B分组的数目T2。
其中,第A类分组的特征为不同分组关联的信息元素可以被同时接收,而同一分组包括E个第B类分组;第B类分组的特征为不同分组关联的信息元素可以被同时接收,而同一分组关联的具有不同信道特征假设的信息元素不能被同时接收。
图7为本发明实施例的示例4考虑基站端TRP/panel数下的PDSCH与PDCCH信道特征假设发生碰撞的示意图。如图7所示,CORESET-2的空间参数下的DL RS为{[c-1,基站天线面板组(NAG,gNode Antenna Group)-a]},CORESET-3的空间参数下的DL RS为{[c-6,NAG-b]};而PDSCH-1和PDSCH-2的空间参数下DL RS均为{[c-2,NAG-a],[c-5,NAG-b]}。
当T2=1时,对于CORESET-2,NAG-a下包含两个空间参数下的DL RS,分别为c-1和c-2,Z=2大于T2,PDSCH-1和PDCCH的信道特征假设发生碰撞。因此,根据PDSCH的优先级高于CORESET的优先级,从UE的角度看,CORESET-2的空间参数被重写成{[c-2,NAG-a]}。同理,CORESET-3的空间参数被重写成{[c-5,NAG-b]}。
当T2=2时,对于CORESET-2,NAG-a下包含两个空间参数下的DL RS,分别为c-1和c-2,Z=2并不大于T2,PDSCH-1和PDCCH的信道特征假设不发生碰撞,所以,从UE的角度看,CORESET-2的空间参数不会被覆盖。同理,CORESET-3的空间参数也不会被覆盖。
示例5
图8为本发明实施例的示例5的跨成员载波(CC,Component Carrier)下的信道特征假设不发生碰撞的示意图。如图8所示,UE上报能力信息,信道状态信息报告中第二类分组的最大数目R1=2,而基站配置的基站的第A类分组数目T1=2。进一步的,接收配置的信息元素的信道特征假设,其中,信道特征假设中包括UAG索引和参考信号索引,确定是否接收信息元素。
在主小区(Pcell)下,CORESET-1和CORESET-3的空间参数均为{[c-1,UAG-a]},而CORESET-2的{[c-3,UAG-a]}。调度偏置小于k=1slot的PDSCH的QCL状态需要服从本小区的最近slot的最低CORESET ID的QCL状态,即对应的TCI状态,因此,Slot-1和Slot-3的调度偏置小于k的PDSCH的空间参数为{[c-1, UAG-a]},而Slot-2的调度偏置小于k的PDSCH的空间参数为{[c-3,UAG-a]}。
在辅小区(Scell)下,CORESET-1和CORESET-3的空间参数均为{[c-5,UAG-b]},而CORESET-2的{[c-7,UAG-b]}。调度偏置小于k=1slot的PDSCH的QCL状态需要服从本小区的最近slot的最低CORESET ID的QCL状态,即对应的TCI状态,因此,Slot-1和Slot-3的调度偏置小于k的PDSCH的空间参数为{[c-5,UAG-b]},而Slot-2的调度偏置小于k的PDSCH的空间参数为{[c-7,UAG-b]}。
对于slot-1到slot-3下,对于同一个UAG小组内的空间参数个数均不大于1,所以,从UE的角度看,不需要重新配置任何空间参数,(或者,TCI状态,或者QCL状态)。
示例6
图9为本发明实施例的示例6的跨CC下的信道特征假设发生碰撞的示意图。UE上报能力信息,信道状态信息报告中第二类分组的最大数目R1=2,而基站配置基站的第A类分组数目T1=2,第A类分组的第B类分组T2=1。进一步的,接收配置的信息元素的信道特征假设,其中,信道特征假设中包括UAG索引和参考信号索引,确定是否接收信息元素。
在Pcell下,CORESET-1、CORESET-2和CORESET-3的空间参数均为{[c-1,UAG-a]}。调度偏置小于k=1slot的PDSCH的QCL状态需要服从本小区的最近slot的最低CORESET ID的QCL状态,即对应的TCI状态,因此,Slot-1、Slot-2和Slot-3的调度偏置小于k的PDSCH的空间参数为{[c-1,UAG-a]}。
在Scell下,CORESET-1和CORESET-3的空间参数均为{[c-5,UAG-b]},而CORESET-2的{[c-7,UAG-a]}。调度偏置小于k=1slot的PDSCH的QCL状态需要服从本小区的最近slot的最低CORESET ID的QCL状态,即对应的TCI状态,因此,Slot-1和Slot-3的调度偏置小于k的PDSCH的空间参数为{[c-5,UAG-b]},而Slot-2的调度偏置小于k的PDSCH的空间参数为{[c-7,UAG-a]}。
对于slot-1和slot-3下,对于同一个UAG小组内的空间参数个数均不大于1,所以,从UE的角度看,不需要重新配置任何空间参数,(或者,TCI状态,或者QCL状态)。
但是,对于slot-2而言,对于UAG-a的空间参数的个数大于1,所以,从UE的角度看,scell下的调度偏置小于k的PDSCH的空间参数和CORESET-2需要服从 Pcell下对应的CORESET和调度偏置小于k的PDSCH空间参数的空间参数,即空间参数{[c-7,UAG-a]}被重写成{[c-1,UAG-a]}。
综上所述,基于本发明实施例提供的技术方案,根据UE端反馈的同时接收参考信号或者信道的能力,以及基站端配置可以支持的同时发送参考信号或者信道的限制信息,指定了在多波束同时发生或者接收下的信道特征假设碰撞的处理办法,以提高系统设计的灵活度,避免对于基站端配置或者调度的过多限制,并且提高了收发端波束或者天线面板资源的利用效率。
