为便于理解本申请实施例的技术方案,对本申请的相关技术进行说明。
载波聚合(Carrier Aggregation,CA)技术和多输入多输出(Multiple Input Multiple Output,MIMO)技术均是提升终端设备的吞吐量的有效手段。其中,CA技术是采用多个载波进行聚合传输的方式提升传输的带宽,从而提升终端设备的吞吐量。MIMO技术是在终端设备具有多个天线的情况下利用该多个发射天线的空间特性来实现多流并行传输,从而提升终端设备的吞吐量。
在LTE系统中,上行吞吐量的提升通常采用CA技术而非MIMO技术实现,因为MIMO技术要求终端设备具有多个天线,而对于终端设备的上行发射来说,采用多个发射天线意味着需要同时具有多个发射链路(或称发射通路)。图2是具有两个发射通路的终端的结构示意图,每个发射通路都需要功率放大器(PA),上变频单元等器件,对终端设备的成本和设计复杂度带来了挑战。
在NR系统中,考虑同时使用CA和MIMO技术提升终端设备的吞吐量,随着CA技术的提升,多载波的聚合带宽越来越宽,因此,网络设备如何对终端设备进行配置以支持终端设备同时工作在CA模式和MIMO模式(即CA和MIMO的联合传输模式)进一步提升 终端设备的吞吐量是一项急需解决的问题。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。
图3是根据本申请实施例的无线通信的方法200的示意性流程图,该方法200可以由图1所示通信系统中的终端设备执行,如图3所示,该方法200包括如下内容:
S210,终端设备向网络设备发送第一信息,所述第一信息用于确定所述终端设备同时工作于载波聚合CA模式和多输入多输出MIMO模式下的最大带宽限制。
在本申请一些实施例中,所述终端设备具有多个发射链路,所述多个发射链路支持的最大带宽相同或不同。所述终端设备可以通过所述多个发射链路工作在上行MIMO模式。
在本申请一些实施例中,所述终端设备具有多个接收链路,所述多个接收链路支持的最大带宽相同或不同。所述终端设备可以通过所述多个接收链路工作在下行MIMO模式。
在本申请一些实施例中,所述第一信息用于直接指示所述终端设备同时工作于载波聚合CA模式和多输入多输出MIMO模式下的最大带宽限制,或者也可以间接指示所述终端设备同时工作于载波聚合CA模式和多输入多输出MIMO模式下的最大带宽限制。即所述第一信息所指示的内容可以用于计算得到所述最大带宽限制,本申请对于所述第一信息的指示方式不作限定。
可选地,在一些实施例中,所述第一信息用于确定所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制,和/或所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制。
例如,所述第一信息可以直接指示或间接指示所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制。
又例如,所述第一信息可以直接指示或间接指示所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制。
在一些实施例中,所述终端设备同时工作于上行CA模式和上行MIMO模式下和同时工作于下行CA模式和下行MIMO模式下分别对应独立的最大带宽限制,分别记为上行最大带宽限制和下行最大带宽限制。
作为一个示例,所述第一信息包括第一最大带宽信息和/或第二最大带宽信息,所述第一最大带宽信息用于指示所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制,所述第二最大带宽信息用于指示所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制。
终端设备分别上报所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制,以及所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制,从而网络设备可以根据上行最大带宽限制配置终端设备的上行工作模式,以及根据下行最大带宽限制配置终端设备的下行工作模式,能够实现对终端设备的工作模式的更精细控制。
可选地,所述第一最大带宽信息和所述第二最大带宽信息可以相同,或者不同。
在一些实施例中,所述终端设备同时工作于上行CA模式和上行MIMO模式下和同时工作于下行CA模式和下行MIMO模式下对应相同的最大带宽限制。
例如,所述第一信息包括第三最大带宽信息,所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制和所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制均根据所述第三最大带宽信息确定。
应理解,以下,结合具体实施例说明所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制的指示方式,所述终端设备同时工作于下行CA模式和下行MIMO模式下的最大带宽限制的指示方式和所述终端设备同时工作于上行CA模式和上行MIMO模式下的最大带宽限制的指示方式类似,为了简洁,这里不作赘述。
在实际应用中,终端设备的发射链路上由于PA等器件的限制导致终端设备可支持的最大带宽有限,比如,有的PA最大可支持200MHz带宽,而有的PA则只能最大支持100MHz。因此,受到发射链路上可支持的最大带宽的限制,当网络设备的配置带宽超过单个链路的最大带宽限制时,终端设备需要采用多个发射链路来实现该配置带宽。
结合图4和图5,以终端设备具有两个发射链路,上行CA通过CC1和CC2实现为例,说明CA带宽和单个发射链路的最大带宽限制和终端设备的工作模式之间的关系。
如图4所示,当网络配置的上行CA带宽没有超过单个发射通路的最大带宽限制时,终端设备采用一个发射通路(包括PA)就可以支持上行CA,同时,该终端设备的两个发射通路之间还可以实现上行MIMO双流传输,因此,终端设备可以同时工作于上行CA模式和MIMO模式下。
如图5所示,当网络配置的上行CA带宽超过单个发射通路的最大带宽限制时,终端需要采用两个发射通路(包括PA)来支持上行CA,此时,受限于终端设备支持的发射通路数量,该终端设备无法同时实现上行MIMO双流传输,因此,终端设备只能工作于CA模式下。
从上面分析可以看出,终端设备是否能够同时支持上行CA和上行MIMO取决于网络设备配置的CA带宽和所述终端设备的单个发射链路支持的最大带宽。
在本申请实施例中,用于实现上行CA的多个载波可以是连续的多个载波或不连续的多个载波,所述CA带宽可以为终端设备配置的所有载波的最高频率和最低频率的差值,或者用于上行CA的所有载波中的最高频率和最低频率的差值。例如,如图6所示,所述终端设备上配置有n个载波,包括频率由高到低的CC1,CC2,……,CCn,其中,则CA带宽可以为CC1到CCn的频率的差值。
为了使得网络设备对终端设备进行合适的配置以使得终端设备同时工作于上行CA模式和上行MIMO模式,或者说,采用CA和MIMO的联合传输模式,所述终端设备可以向网络设备上报所述终端设备的单个发射链路支持的最大带宽。例如,所述第一信息可以包括所述终端设备的单个发射链路支持的最大带宽。
作为一个示例,所述第一信息包括所述终端设备的多个发射链路中的每个发射链路支持的最大带宽。
作为又一示例,所述第一信息包括所述终端设备的多个发射链路中的第一发射链路支持的最大带宽,其中,所述第一发射链路为所述多个发射链路中支持的最大最宽最小的发射链路。
可选地,所述多个发射链路支持的最大带宽可以相同或不同。
在一些实施例中,在所述多个发射链路支持的最大带宽相同的情况下,所述终端设备可以只上报一个最大带宽信息,在所述多个发射链路支持的最大带宽不同的情况下,所述终端设备可以上报每个发射链路的最大带宽信息,或者,也可以只上报该多个发射链路的最大带宽信息中的最小值。
在网络设备接收到该终端设备上报的最大带宽限制的情况下,网络设备可以根据该最大带宽限制和终端设备的工作模式,进行合适的配置。例如,若网络设备仅需配置终端设备工作在上行CA模式而不需要配置终端设备工作在上行MIMO模式,则网络设备可以配置超过该最大带宽限制的CA带宽,或者,若网络设备仅需配置终端设备工作在上行MIMO模式,或者需要配置终端设备同时工作在上行CA模式和上行MIMO模式,则网络设备可配置的CA带宽不能超过该最大带宽限制。
在一些实施例中,所述第一信息可以通过任一上行消息或信令发送给网络设备,例如,上行无线资源控制(Radio Resource Control,RRC)消息,上行媒体接入控制(Media Access Control,MAC)信令等。
在本申请一些实施例中,所述终端设备也可以直接上报所述最大带宽限制对应的带宽值,或者也可以上报所述最大带宽限制对应的索引信息,该索引信息可以用于指示所 述最大带宽限制,或者,所述最大带宽限制对应的范围,本申请实施例对于所述最大带宽限制的指示方式不作具体限定。
在一些实施例中,所述第一信息包括所述最大带宽限制对应的CA带宽等级(CA bandwidth class)或所述最大带宽限制对应的带宽值。
例如,在用于上行CA为带内连续CA,或者说,用于上行CA的多个载波为带内连续的多个载波时,此情况下,所述终端设备可以上报最大带宽限制对应的CA带宽等级,或者,也可以上报该最大带宽限制对应的带宽值。
在一些实施例中,所述最大带宽限制对应的CA带宽等级为所述终端设备上所有配置的带内连续载波(或者,用于上行CA的所有载波)中的最高频率和最低频率的差值在多个预设带宽范围中对应的带宽范围,所述最大带宽限制对应的带宽值为所述终端设备上配置的所有连续载波的最高频率和最低频率的差值。
表1是一种CA带宽等级的示例,每个CA带宽等级对应相应的带宽范围(或称聚合信道带宽范围),前述的多个预设带宽范围可以包括表1中的带宽范围,终端设备可以根据上行CA对应的多个载波中的最高频点和最低频点的差值确定一个带宽,进一步在表1中查找该带宽所属的带宽范围,然后向网络设备上报该带宽范围对应的CA带宽等级。或者,也可以直接上报该带宽值,例如,50MHz,100MHz,150MHz等。

A | BW Channel≤BW Channel,max | 1 |

M | 50MHz≤BW ChannelCA≤200MHz | 3 |
N | 80MHz≤BW ChannelCA≤300MHz | 4 |
O | 100MHz≤BW ChannelCA≤400MHz | 5 |
在本申请一些实施例中,所述第一信息包括所述最大带宽限制对应的CA频率间隔等级或所述最大带宽限制对应的频率间隔值。
例如,在用于上行CA为带内不连续CA,或者说,用于上行CA的多个载波为带内不连续的多个载波时,此情况下,所述终端设备可以上报最大带宽限制对应的CA频率间隔等级,或者,上报该最大带宽限制对应的频率间隔值。
在一些实施例中,所述CA频率间隔等级为所述终端设备上所有配置的带内非连续载波(或者,用于上行CA的所有载波)的最高频率和最低频率的差值在多个预设频率间隔范围中对应的频率间隔范围,所述频率间隔值为所述终端设备上所有配置的带内非连续载波的最高频率和最低频率的差值。
表2是一种CA频率间隔等级的示例,每个CA频率间隔等级对应相应的频率间隔范围,前述的多个频率间隔范围可以包括表2中的频率间隔范围,终端设备可以根据上行CA对应的多个载波中的最高频点和最低频点的差值确定一个频率间隔,进一步在表2中查找该频率间隔所属的频率间隔范围,然后向网络设备上报该频率间隔范围对应的CA频率间隔等级。或者,也可以直接上报该频率间隔值,例如,50MHz,100MHz,150MHz等。
表2
CA频率间隔等级 | 最大允许的频率间隔 |
I | 100MHz |
II | 200MHz |
III | 600MHz |
综上所述,终端设备通过上报单个链路的最大带宽限制(或者说,单个链路的最大带宽能力),或者,同时工作在CA模式和MIMO模式(CA和MIMO联合传输)下的最大带宽限制(或者说,CA+MIMO模式支持的最大带宽能力),从而网络设备可以根据该终端设备的工作模式结合该最大带宽限制对终端设备进行合适的配置,例如,终端设备只需工作在CA模式时,配置的聚合带宽可以超过该最大带宽限制,或者终端设备需要同时工作于CA模式和MIMO模式时,配置的聚合带宽不超过该最大带宽限制,有利于满足终端设备的不同场景的传输需求。
