Description

一种发送信息、接收信息的方法及装置

技术领域
本申请涉及移动通信技术领域,尤其涉及一种发送信息、接收信息的方法及装置。
背景技术
在长期演进(Long term evolution,LTE)系统中,终端设备支持同时接入到两个网络设备,这种接入方式称为双连接(Dual Connectivity,DC),其中一个网络设备为主网络设备,另一个网络设备为辅网络设备。在无线通信系统的发展演进过程中,运营商会同时部署第五代(5th generation,5G)新空口(New radio interface,NR)系统和长期演进(Long term evolution,LTE)系统,因此,在一个双连接场景中,终端设备支持同时接入到LTE的网络设备和NR的网络设备,因为LTE又被称为演进的通用陆面无线接入(Evolved Universal Terrestrial Radio Access,E-UTRA),所以这种接入方式被称为演进的通用陆面无线接入与新空口双连接(E-UTRA NR Dual Connectivity,EN-DC)。在EN-DC模式下,LTE的网络设备为主网络设备,NR的网络设备为辅网络设备。在又一个双连接场景中,也可以支持新空口与演进的通用陆面无线接入双连接(NR E-UTRA Dual Connectivity,NE-DC),即NR的网络设备为主网络设备,LTE的网络设备为辅网络设备。由于EN-DC和NE-DC的终端都会接入到两个不同的无线接入技术的网络设备,所以这些DC模式也可以统称为多无线接入技术双连接(Multi-RAT Dual Connectivity,MR-DC)。当然,还存在其他双连接场景,如终端设备支持同时接入到LTE的网络设备和LTE的网络设备,或者,终端设备支持同时接入到NR的网络设备和NR的网络设备。
然而,目前终端设备与网络设备在采用双连接技术进行通信时,还存在通信效率需要提升的问题。

在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的通信资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据发送服务。此外,在其它可能的情况下,网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述,本申请实施例中,为终端设备提供无线通信功能的装置称为网络设备。
双连接场景中,存在两个小区组,即主小区组(Master Cell Group,MCG)和辅小区组(Secondary Cell Group,SCG)。其中MCG包括一个主小区(Primary Cell,PCell),可选的,还可以额外包括一个或多个辅小区(Secondary Cell,Scell),SCG包括一个主辅助小区(Primary Secondary Cell,PSCell),可选的,还可以额外包括一个或多个SCell。管理MCG的网络设备称为主网络设备,管理SCG的网络设备称为辅网络设备。
本申请实施例中,主网络设备为LTE网络设备(如eNB)、5G网络设备(如gNB)或未来通信系统中的网络设备中的一个,辅网络设备也为LTE网络设备、5G网络设备或未来通信系统中的网络设备中的一个。并且主网络设备和辅网络设备可以是相同制式的网络设备,比如都是eNB,也可以是不同制式的网络设备,比如主网络设备是eNB,辅网络设备是gNB。本申请对于主网络设备和辅网络设备的通信制式不做限定。
需要说明的是,一个小区可以包括一个下行载波,和至少一个上行载波。在一种情况下,一个小区包括一个下行载波和一个上行载波,该下行载波和上行载波可以对应相同的频段,也可以对应不同的频段。在另一种情况下,一个小区包括一个下行载波和两个上行载波,该下行载波与该两个上行载波的中的一个上行载波采用相同的频段,与另一个上行载波采用不同的频段。因此,本申请中的小区对应于下行载波。
一个小区组可以包含至少一个小区,通常不同的小区组可认为对应于不同的网络设备, 同一个小区组里的不同小区可对应相同的网络设备,也可以对应不同的网络设备,本申请并不限定。
本申请中,终端设备可以在至少两个上行载波上同时发送信号。这些上行载波可以来自不同的小区组,也可以来自同一个小区组。当来自同一小区组是,该至少两个上行载波可以对应同一下行载波,即属于同一小区,或者可以对应不同下行载波,即属于不同小区。
比如,当终端设备在两个上行载波上同时发送信号时,该两个上行载波可以分别称为第一上行载波和第二上行载波。当本申请的方法中的第一上行载波和第二上行载波来自于同一小区组时,该方法可以应用于非DC场景,例如,载波聚合场景或增补上行载波(supplementary uplink,SUL)场景等。需要说明的是,当第一上行载波和第二上行载波来自于同一小区组时,此时也可以认为没有小区组,仅仅是不同的上行载波。
目前支持MR-DC的终端设备有如下三种天线配置,或者称为终端设备对应三种不同的发送天线能力:
1)配置1:K1根发送天线(Tx)分配给NR,K2根发送天线分配给LTE。
基于该配置1,终端设备可以在NR的上行载波和LTE的上行载波上同时发送信号。其中,NR的上行载波称为第一上行载波,LTE的上行载波称为第二上行载波;或者,NR的上行载波称为第二上行载波,LTE的上行载波称为第一上行载波。
终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数记为M1,终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数记为M2,终端设备在第一上行载波和第二上行子载波上同时发送信号时总共支持的最大发送天线数记为M。
以NR的上行载波称为第一上行载波,LTE的上行载波称为第二上行载波为例,则M1=K1,M2=K2,M=M1+M2=K1+K2。
可以看出,该配置1中,分配给NR的发送天线与分配给LTE的发送天线之间不共享。
2)配置2:K3根发送天线分配给NR,K4根发送天线可供LTE和NR时分共享。
基于该配置2,以NR的上行载波称为第一上行载波,LTE的上行载波称为第二上行载波为例,则M1=K3+K4,M2=K4,M=K3+K4,且M<M1+M2。
可以看出,该配置2中,分配给NR发送天线与分配给LTE的发送天线之间共享。
3)配置3:K5根发送天线分配给NR,K6根发送天线分配给LTE。
该配置3与上述配置1的主要区别在于:K5与K1的数值不同,和/或,K6与K2的数值不同。
以NR的上行载波称为第一上行载波,LTE的上行载波称为第二上行载波为例,则M1=K5,M2=K6,M=M1+M2=K5+K6。
可以看出,该配置3中,分配给NR的发送天线与分配给LTE的发送天线之间不共享。
然而,基于上述场景进行通信的终端设备,其有在LTE上行载波和NR上行载波之间切换发送上行信号的需求,但是在现有技术中,由于网络设备无法获知终端设备发送天线的配置情况,从而使得网络设备不能够区分发送天线能力不同的终端设备,因而导致网络设备无法为终端设备采用相适应的调度策略,影响终端设备与网络设备之间的通信效率。
需要说明的是,本申请中,发送天线也可以称为发送链路,或射频链路,或射频通道等等。
需要说明的是,本申请对上述K1、K2、K3、K4、K5、K6的取值大小没有限定,且 这些数值之间可以部分相等。
如图2所示,为终端设备天线配置示意图。该示例中:
针对配置1,K1=1,K2=1,总共2根发送天线,且M1=1,M2=1,M=2。
针对配置2,K3=1,K4=1,总共2根发送天线,且M1=2,M2=1,M=2。
针对配置3,K5=2,K6=1,总共3根发送天线,且M1=2,M2=1,M=3。
上述三种天线配置分别对应终端设备的三种发送天线能力。为使得网络设备能够区分具备不同发送天线能力的终端设备,从而为不同终端设备采用相适应的调度策略,网络设备需要获知终端设备的发送天线能力。
本申请提供一种终端设备上报发送天线能力的方法,即终端设备告知网络设备:终端设备支持上述三种配置中的哪一种。
如图3所示,为本申请提供的一种方发送信息和接收信息的方法,该方法包括以下步骤:
步骤301,终端设备生成第一消息,第一消息包括第一指示信息。
该第一指示信息也可以称为发送天线能力指示信息、或称为天线能力指示信息、或称为天线配置指示信息等。需要说明的是,此处的天线也可以替换为“射频通道”或“射频链路”或“功率放大器”等与发送天线强相关的描述,也就是说第一指示信息也可以称为射频通道能力指示信息,或射频链路能力指示信息,或功率放大器能力指示信息。本实施例并不限定第一指示信息的名称。
该第一消息在具体实现中例如可以是终端设备上报能力的消息,该消息中包括本申请中的上述第一指示信息,同时还可以包括其他能力的指示信息,如终端设备支持的调制方式的能力指示信息,以及终端设备支持的上行多天线预编码的能力指示信息等等。因此,终端设备通常会先根据自身的能力确定第一指示信息,然后将第一指示信息封装到第一消息从而生成第一消息。
第一指示信息用于指示终端设备在至少两个上行载波上同时发送信号时总共支持的最大发送天线数(用M表示),或用于指示终端设备在至少两个上行载波上发送信号的发送天线之间是否共享。
步骤302,终端设备向网络设备发送第一消息。相应地,网络设备可以接收到该第一消息。
步骤303,网络设备获取第一消息中的第一指示信息。
网络设备获取到第一指示信息后,可以根据第一指示信息确定终端设备总共支持的最大发送天线数。进而,网络设备可以根据终端设备总共支持的最大发送天线数,确定终端设备的天线配置属于上述三种配置中的哪一种。
例如,当第一指示信息用于指示终端设备在第一上行载波和第二上行载波上同时发送信号时总共支持的最大发送天线数M,或用于指示终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间是否共享时,则网络设备可以根据终端设备仅在第一上行载波上发送信号时支持的第一最大天线数(用M1表示)、终端设备仅在第二上行载波上发送信号时支持的第二最大天线数(用M2表示),以及终端设备总共支持的最大发送天线数M,确定终端设备的天线配置属于上述三种配置中的哪一种。其中,终端设备仅在第一上行载波上发送信号时支持的第一最大天线数M1、终端设备仅在第二上行载波上发送信号时支 持的第二最大天线数M2,可以是协议预定义的,也可以是终端设备预先上报给网络设备的。
需要说明的是,该实施例中的第一上行载波和第二上行载波可以为来自不同小区组的上行载波。例如,第一上行载波来自主小区组,第二上行载波来自辅小区组,当然也可以反过来。进一步的,第一上行载波和第二上行载波对应的小区组可以是属于相同的无线接入技术,也可以对应不同的无线接入技术,如第一上行载波对应LTE,第二上行载波对应NR,当然也可以反过来。该实施例中的第一上行载波和第二上行载波可以为来自同一小区组的不同上行载波。
需要说明的是,图3实施例中的网络设备可以是主网络设备,也可以是辅网络设备,本申请不做限定。
基于上述方案,终端设备通过第一指示信息,使得网络设备能够区分不同发送天线能力的终端设备,从而网络设备能够为不同发送天线能力的终端设备采用相适应的调度策略,有助于提升终端设备与网络设备之间的通信效率。
下面给出上述第一指示信息的几种不同的实现方法。
方法一,第一指示信息用于指示终端设备同时在第一上行载波和第二上行载波上发送信号时总共支持的最大发送天线数M。
针对该方法一,分为以下两种情形:
情形1,第一指示信息指示的最大发送天线数M小于终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数M1与终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数M2之和,即M<M1+M2。
针对该情形1,由于M<M1+M2,因此网络设备可以确定终端设备的天线配置应属于上述配置2。即终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间共享。
情形2,第一指示信息指示的最大发送天线数M等于终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数M1与终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数M2之和,即M=M1+M2。
针对该情形2,由于M=M1+M2,因此网络设备可以确定终端设备的天线配置应属于上述配置1或配置3,即终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间不共享。
进一步地,网络设备可以根据终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数M1和终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数M2,确定终端设备的天线配置为配置1或配置3。比如,M1=K1,M2=K2,则网络设备确定终端设备的天线配置为配置1。再比如,M1=K5,M2=K6,则网络设备确定终端设备的天线配置为配置3。
方法二,第一指示信息用于指示终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间是否共享。
针对该方法二,分为以下两种情形:
情形1,第一指示信息指示终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间共享。
针对该情形1,由于终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间共享,因此网络设备可以确定终端设备的天线配置应属于上述配置2。
情形2,第一指示信息指示终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间不共享。
针对该情形2,由于终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间不共享,因此网络设备可以确定终端设备的天线配置应属于上述配置1或配置3。
进一步地,网络设备可以根据终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数M1和终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数M2,确定终端设备的天线配置为配置1或配置3。比如,M1=K1,M2=K2,则网络设备确定终端设备的天线配置为配置1。再比如,M1=K5,M2=K6,则网络设备确定终端设备的天线配置为配置3。
针对上述方法一的情形1、或方法二的情形1,作为一种实现方法,终端设备在第一上行载波和第二上行载波之间切换时的切换时间等于t1,t1大于0。例如,当第一上行载波和第二上行载波来自不同小区组、且小区组对应不同的无线接入技术时,该切换时间t1用于终端设备将共享天线从LTE上行转换到NR上行,或用于终端设备将共享天线从NR上行转换到LTE上行。该切换时间t1可以是终端设备上报给网络设备的,也可以是协议预定义。比如,当切换时间t1包括一个或多个值时,可以由终端设备上报给网络设备,例如该切换时间t1可以是35us,120us等中的一个或多个。再比如,当切换时间t1仅有一个值时,则可以无需终端设备上报。该方案中,不管终端设备在第一上行载波实际用到了多少根发送天线,以及在第二上行载波实际用到了多少根发送天线,都按照同样的切换时间t1进行切换。
针对上述方法一的情形1、或方法二的情形1,作为又一种实现方法,终端设备在第一上行载波上采用N1根发送天线发送信号和在第二上行载波上采用N2根发送天线发送信号之间切换时的切换时间等于t1,t1大于0。其中,N1+N2>M,N1<=K3,N2<=K4。和/或,终端设备在第一上行载波上采用N3根发送天线发送信号和在第二上行载波上采用N4根发送天线发送信号之间切换时的切换时间等于t2,t2大于或等于0,N3+N4<=M,N3<=K3,N3<=K4。其中,切换时间t1的描述参考前述描述,切换时间t2可以等于0或接近于0。该方案中,当终端设备在第一上行载波实际用到了的发送天线的数量N1与在第二上行载波实际用到了的发送天线的数量N2之和大于M,则切换时间为t1,即发送天线不能同时满足NR发送和LTE发送,因此需要切换。当终端设备在第一上行载波实际用到了的发送天线的数量N3与在第二上行载波实际用到了的发送天线的数量N4之和小于或等于M,则切换时间为t2,即发送天线能够同时满足NR发送和LTE发送,因此不需要切换。
针对上述方法一的情形2、或方法二的情形2,终端设备在第一上行载波和第二上行载波之间切换时的切换时间等于t2。切换时间t2可以等于0或接近于0。该方案中,由于终端设备在第一上行载波发送信号的发送天线与在第二上行载波发送信号的发送天线之间没有共享发送天线,因此切换时间为t2,即不需要切换。
方法三,第一指示信息用于指示终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间的切换时间。
针对该方法三,分为以下两种情形:
情形1,第一指示信息指示的终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间的切换时间等于t1,t1大于0。
针对该情形1,由于切换时间等于t1,表明终端设备在第一上行载波和第二上行载波 上发送信号的发送天线之间共享,因此网络设备可以确定终端设备的天线配置应属于上述配置2。
情形2,第一指示信息指示的终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间的切换时间等于t2,t2等于0或接近于0。
针对该情形2,由于切换时间等于t2,表明终端设备在第一上行载波和第二上行载波上发送信号的发送天线之间不共享,因此网络设备可以确定终端设备的天线配置应属于上述配置1或配置3。
进一步地,网络设备可以根据终端设备仅在第一上行载波上发送信号时支持的第一最大发送天线数M1和终端设备仅在第二上行载波上发送信号时支持的第二最大发送天线数M2,确定终端设备的天线配置为配置1或配置3。比如,M1=K1,M2=K2,则网络设备确定终端设备的天线配置为配置1。再比如,M1=K5,M2=K6,则网络设备确定终端设备的天线配置为配置3。
方法四,第一指示信息用于指示终端设备的天线配置类型。
比如,可以使用2比特来指示三种天线配置类型。作为示例,使用00指示上述配置1,01指示上述配置2,10指示上述配置3。
针对上述方法一至方法四,作为一种实现方法,上述步骤301的第一消息还包括第二指示信息,第二指示信息用于指示终端设备在第一上行载波上发送信号的发送天线与在第二上行载波上发送信号的发送天线之间共享的发送天线数X。
需要说明的是,本申请上述方案并不限于不同载波之间的天线共享,也可以应用于不同频段之间的天线共享。
需要说明的是,当由终端设备向网络设备上报终端设备仅在第一上行载波上发送信号时支持的第一最大天线数M1时,也可以复用现有终端设备上报的指示信息。其中,这里的第一上行载波指的是NR中的上行载波。
例如,现有技术中SRS-TxSwitch单元中的supportedSRS-TxPortSwitch字段,该字段直接指示终端设备SRS天线切换的能力,如1发4收(1根发送天线和4根接收天线),2发4收等,从而间接指示终端设备仅在第一上行载波上发送信号时支持的第一最大天线数M1等于探测参考信号(Sounding Reference Signal,SRS)天线切换能力中的发送天线数。
又例如,现有技术中的MIMO-Layers字段,该字段直接指示终端设备上行发送的最大空间层数,如1层、2层和4层中的一个,从而间接指示终端设备仅在第一上行载波上发送信号时支持的第一最大天线数M1等于最大空间层数。
又例如,现有技术中的maxNumberSRS-Ports-PerResource字段,该字段直接指示一个SRS资源中最大SRS端口数,可以是1个、2个和4个中的一个,从而间接指示终端设备仅在第一上行载波上发送信号时支持的第一最大天线数M1等于一个SRS资源中的最大SRS端口数。
