Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法、终端设备和网络设备。
背景技术
截至目前,新空口(New Radio,NR)系统引入了基于节能信号的辅小区(Secondary Cell,SCell)休眠(SCell dormancy)功能。网络设备为每个SCell或辅小区组(Secondary Cell Group,SCG)配置专用于休眠的休眠BWP(dormant BWP)。基于此,在终端设备激活了SCell或SCG且无数据传输情况下,网络设备可以通过下行控制信息(Downlink Control Information,DCI)中携带的节能信号指示终端设备在相应的SCell或SCG上激活休眠BWP。终端设备可以在休眠BWP上不监听物理下行控制信道(Physical Downlink Control Channel,PDCCH),只执行信道状态信息(Channel State Information,CSI)的测量以及上报,便于降低终端设备的功耗。

如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本申请实施例仅以通信系统100进行示例性说明,但本申请实施例不限定于此。也就是说,本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、、物联网(Internet of Things,IoT)系统、窄带物联网(Narrow Band Internet of Things,NB-IoT)系统、增强的机器类型通信(enhanced Machine-Type Communications,eMTC)系统、5G通信系统(也称为新无线(New Radio,NR)通信系统),或未来的通信系统等。

在5G的演进中,对用户设备(User Equipment,UE)节电提出了更高的要求。
在一些实施例中,可以通过非连续接收(Discontinuous Reception,DRX)机制实现UE的节能,对于DRX机制,在每个激活期(on duration)内,UE需要不断检测物理下行控制信道(Physical Downlink Control Channel,PDCCH)来判断基站是否调度发给自己的数据传输。但是对于大部分UE来说,可能在很长一段时间没有接收数据传输的需要,但是仍然需要保持定期的唤醒机制来监听可能的下行传输,对于这类UE,节电有进一步优化的空间。
在一些实施例中,可以通过引入节能信号进一步实现UE的节能。节能信号可以与DRX机制结合使用,终端设备在DRX激活期之前接收节能信号。当终端设备在一个DRX周期有数据传输时,节能信号用于唤醒终端设备,以在DRX激活期监听PDCCH;否则,当终端设备在一个DRX周期没有数据传输时,节能信号用于不唤醒终端设备,终端在DRX激活期不需要监听PDCCH。相比DRX机制,在 终端设备没有数据传输时,终端可省略DRX激活期内对PDCCH监听,从而实现进一步节能。可选的,节能信号可以通过下行控制信息(Downlink Control Information,DCI)格式(format)2_6承载。终端设备在DRX激活期之外的时间被称为非激活时间,在DRX激活期的时间被称为激活时间。
图2是本申请实施例提供的DRX周期的示例。
如图2所示,终端设备在DRX激活期之前接收节能信号。节能信号可用于指示终端设备监听或不监听PDCCH;节能信号用于指示终端设备监听PDCCH时,终端设备在相应的DRX激活期监听PDCCH;节能信号用于指示终端设备不监听PDCCH时,终端设备在相应的DRX激活期不监听PDCCH。相比DRX机制,在终端设备没有数据传输时,终端可省略DRX激活期内对PDCCH监听,从而实现进一步节能。
在一些实施例中,还可以通过引入辅小区(Secondary Cell,SCell)/辅小区组(Secondary Cell Group,SCG)休眠(dormancy)功能进一步实现UE的节能。网络为每个SCell/SCG配置专用的休眠(dormant)带宽部分(Bandwidth Part,BWP)。在激活了SCell/SCG但无数据传输情况下,可以通过DCI指示UE在相应的SCell/SCG上激活休眠BWP。UE在该休眠BWP上不监听PDCCH,仅执行信道状态信息(Channel State Information,CSI)测量及上报,便于UE节电。
示例性地,SCell/SCG休眠触发过程包括两种情况:
情况1:激活时间外的SCell/SCG休眠触发。
激活时间外的SCell/SCG休眠触发可以通过DCI格式2_6中的专用比特来携带休眠指示。由于休眠指示可为多终端指示等原因,每个终端设备的休眠指示限制在5个比特及以下。每个比特用于指示SCell/SCG的休眠或者非休眠。SCG可包括一个或多个SCell,SCG休眠可以指SCG中的每一个SCell休眠,SCG退出休眠可以指SCG中的每一个SCell退出休眠。从终端射频设计的能耗上来说,同一频段的载频(即SCell)的开关可以相关联。一个频段内载频同时打开收发与独立打开的功耗差别较小。载波分组(即SCG)由网络设备配置决定。
终端设备在一个SCell上只配置一个休眠BWP。当终端设备被指示退出休眠BWP时,需要选择是哪一个非休眠BWP。网络设备可以为终端设备配置第一非休眠BWP,为了让终端侧和基站减少不必要的BWP切换,NR规定了终端设备在当前激活是休眠BWP且收到退出休眠指示的情况下才会切换到第一费休眠BWP。终端在当前激活是某一非休眠BWP,在收到退出休眠指示时只需要保持当前的BWP即可。
情况2:激活时间内的SCell/SCG休眠触发。
激活时间内的SCell/SCG休眠触发通过普通的PDCCH指示。
PDCCH指示指示可以包括以下两种方式。
方式1:
在用于调度数据传输的调度DCI中增加专用比特。由于调度DCI已经有较大负荷,专用比特也限制在5个比特及以下。每个比特用于指示SCell/SCG的休眠或者非休眠。基站可以同样利用同一频段的载频的开关相关联的特性进行SCell分组的配置以达到高效使用休眠信令。专用比特增加在DCI格式0_1和1_1两个格式下。这种方式的特点是调度DCI可以随时发起休眠指示。但是,即使在不需要改变SCell休眠情况下,调度DCI仍然需要传输这个专用比特。这就带来了不必要的开销。此时可以考虑采用方式2。
方式2:
重定义调度DCI中的域,将调度DCI专门用作SCell休眠指示。DCI格式1_1的频率资源指示域为全0或者全1时,表示调度DCI的如下域用于指示15个SCell的休眠:
传输块1的调制与编码策略(Modulation and Coding Scheme,MCS)。
传输块1的新数据指示符。
传输块1的冗余版本指示。
混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程(process)号。
天线端口(Antenna port(s))。
解调参考信号(Demodulation Reference Signal,DMRS)序列初始化值。
这种方式中,调度DCI不调度数据,但仍需要占用整个DCI格式。在SCell/SCG比较少时,开销会较大。NR的HARQ-ACK是根据对调度数据的解码而反馈。方式1可实现基站和终端的通信握手,有利于两侧的同步。方式2需要有另一种方式支持握手。因此对于方式2,需要进一步引入基于PDCCH的HARQ-ACK反馈定时。例如,可以在在不同的子载波间隔(subcarrier spacing,SCS)采用固定的定时关系。
对于激活时间内的SCell/SCG休眠触发,第一种和第二种方式可以根据场景的需求由基站灵活配 置。
由上可知,SCell/SCG退出休眠的触发和SCell/SCG休眠的触发类似,基站配置第一非休眠BWP给终端设备。不考虑BWP非激活定时器(bwp-InactivityTimer)超时的情况,在激活时间内终端设备只有在当前激活是休眠BWP且收到退出休眠指示的情况下才会切换到第一非休眠BWP。终端设备在当前激活是某一非休眠BWP,在收到退出休眠指示时只需要保持当前的BWP即可。
图3是本申请实施例提供的通过PDCCH接收节能信号的示意图。
如图3所示,终端设备的PCell上激活的BWP为激活BWP,终端设备的SCell 1上激活的BWP为非休眠BWP,终端设备的SCell 2上激活的BWP为非休眠BWP。终端设备可以通过PCell上的PDCCH接收SCell 1休眠指示,此时所述终端设备激活SCell 1上的休眠BWP;进一步的,终端设备还可以通过PCell上的PDCCH接收SCell 1退出休眠指示,此时所述终端设备激活SCell 1上的非休眠BWP。类似的,终端设备可以通过PCell上的PDCCH接收SCell 2休眠指示,此时所述终端设备激活SCell 2上的休眠BWP。
在一些实施例中,为了UE的进一步节电,还可以考虑引入唤醒接收机接收节能信号。
其中,唤醒接收机具有极低成本、极低复杂度和极低功耗的特点。唤醒接收机接收的信号为无线电信号,其主要通过基于包络检测的方式进行接收。无线电信号可以是对载波信号进行ASK调制得到的包络信号。包络信号的解调可以基于无线射频信号提供的能量驱动低功耗电路来完成,因此唤醒接收机可以是无源的。唤醒接收机也可以通过终端设备进行供电,无论哪种供电方式,唤醒接收机相比UE的传统接收机极大的降低了功耗。
但是,由于唤醒接收机接收的信号、波形、调制方式以及解调方式与基于PDCCH承载的信号、波形、调制方式以及解调方式不同,因此,如何利用唤醒接收机接收上文涉及的节能信号是本领域亟需解决的技术问题。作为一种可能的实现方式,可以由唤醒接收机接收网络设备发送的无线电信号触发终端设备接收基于PDCCH承载的信号。
图4是本申请实施例提供的通过唤醒接收机和主接收机接收节能信号的示意图。
如图4所示,终端设备可包括唤醒接收机和UE主接收机,唤醒接收机和UE主接收机相连,唤醒接收机可用于触发主接收机的打开,唤醒接收机可以和UE结合在一起,作为UE接收机的一个附加模块,也可以单独作为一个UE的唤醒功能模块。唤醒接收机以无线电信号的形式先接收节能信号,唤醒接收机接收到的节能信号可作为唤醒信号唤醒主接收机,主接收机收到唤醒信号后,触发其接收基于基于PDCCH承载的节能信号。
由此可见,在引入唤醒接收机的情况下,若终端设备接收休眠或退出休眠指示时,如果还基于PDCCH接收,唤醒接收机以无线电信号的形式先接收节能信号,用于唤醒主接收机,虽然可以通过关闭主收发机来省电。由于休眠指示依赖于PDCCH的接收,而接收PDCCH需要开启UE的主收发机,因此,需要额外发送用于唤醒主接收机的无线电信号,进而增加了终端设备的功耗。有鉴于此,本申请实施例提供了一种无线通信方法、终端设备和网络设备,能够降低终端设备的功耗。

如图5所示,所述方法200可包括:

其中,所述指示信息用于指示至少一个辅小区SCell休眠、退出休眠、激活或去激活;所述至少一个SCell为第一SCell或第一辅小区组SCG。

下面结合具体实施例对本申请的方案进行说明。
实施例1:
本实施例中,终端设备通过WUR信号接收指示信息,所述指示信息用于指示第一SCG休眠。
在载波聚合(Carrier Aggregation,CA)和双连接(Dual Connectivity,DC)场景下,当激活了所述第一SCG但无数据传输情况下,可以通过DCI指示终端设备在所述第一SCG上休眠,即激活所述第一SCG上的休眠BWP。在休眠BWP上,终端设备不监听PDCCH,仅执行CSI测量及上报,有利于降低终端设备的功耗。
当终端设备具备的唤醒接收机时,所述终端设备可以接收一些与节能有关的唤醒信号,可以使所述终端设备关闭主收发机来实现节电。在主收发机关闭期间,所述终端设备是不能检测PDCCH的。
当所述第一SCG激活且无数据传输时,终端设备可能已经开启了唤醒接收机且关闭了主收发机。此外由于所述第一SCG是激活的,因此所述第一SCG有可能处于非休眠状态。这种状态下,当所述第一SCG无数据传输时,需要通过所述指示信息指示所述第一SCG进入休眠状态。如果通过PDCCH接收所述指示信息,需要先通过唤醒接收机接收唤醒信号,以唤醒所述终端设备的的主收发机,再通过主收发机接收PDCCH,获得所述指示信息;但是,这种先唤醒再接收的过程,会增加终端的功耗和传输时延。
本实施例中,通过WUR信号接收用于指示所述第一SCG休眠的指示信息,可以进一步减少由于终端设备检测和解调PDCCH造成的耗电。即当所述第一SCG激活且无数据传输时,所述终端设备可能已经开启了唤醒接收机且关闭了主收发机,此时,所述终端设备可以通过WUR信号接收所述指示信息,从而在所述第一SCG上进行入休眠状态,即可以激活所述第一SCG中的每一个SCell上的休眠BWP。
示例性地,所述终端设备可以在PCell或PCG上通过唤醒接收机接收所述指示信息,也可以在SCell或SCG上通过唤醒接收机接收所述指示信息,例如,所述终端设备可以在所述第一SCG上接收所述指示信息,也可以在不同于所述第一SCG的SCG上接收所述指示信息,本申请对此不作具体限定。
应当理解,所述指示信息用于指示第一SCell休眠的方案与所述指示信息指示第一SCG休眠的方案类似,为避免重复,此处不再赘述。
实施例2:
本实施例中,终端设备通过WUR信号接收指示信息,所述指示信息用于指示第一SCG退出休眠。
当终端设备具备的唤醒接收机时,所述终端设备可以接收一些与节能有关的唤醒信号,可以使所述终端设备关闭主收发机来实现节电。在主收发机关闭期间,所述终端设备是不能检测PDCCH的。
当所述第一SCG激活且无数据传输时,终端设备可能已经开启了唤醒接收机且关闭了主收发机。此外由于所述第一SCG是激活的,因此所述第一SCG有可能处于休眠状态。这种状态下,当所述第一SCG有数据传输时,需要通过所述指示信息退出休眠状态。如果终端设备通过PDCCH接收所述指示信息,则需要先通过WUR信号唤醒UE的主收发机,再由主收发机接收通过PDCCH接收所述指示信息。例如,通过PDCCH中的休眠指示域的所述第一SCG激对应的比特置为1来指示所述第一SCG退出休眠状态。但是,这种先唤醒再接收的过程,会增加终端的功耗和传输时延
本实施例中,通过WUR信号接收所述指示信息,可以在只开启唤醒接收机的情况下接收所述指示信息,能够降低所述终端设备的功耗。即当所述第一SCG激活且有数据传输时,所述终端设备可能已经开启了唤醒接收机且关闭了主收发机,此时,所述终端设备可以通过WUR信号接收所述指示信息,从而在所述第一SCG上退出休眠状态,即激活所述第一SCG中的每一个SCell上的非休眠BWP。例如, 激活所述第一SCG中的每一个SCell上的预定义的非休眠BWP。
示例性地,所述终端设备可以在PCell或PCG上通过唤醒接收机接收所述指示信息,也可以在SCell或SCG上通过唤醒接收机接收所述指示信息,例如,所述终端设备可以在所述第一SCG上接收所述指示信息,也可以在不同于所述第一SCG的SCG上接收所述指示信息,本申请对此不作具体限定。
应当理解,所述指示信息用于指示第一SCell休眠的方案与所述指示信息指示第一SCG休眠的方案类似,为避免重复,此处不再赘述。
图6是本申请实施例提供的指示SCG休眠或退出休眠的示意图。
如图6所示,终端设备的PCG上开启唤醒接收机,终端设备的SCG 1上激活的BWP为非休眠BWP,终端设备的SCG 2上激活的BWP为非休眠BWP。终端设备可以通过PCell上的WUR信号接收SCG 1休眠指示,此时所述终端设备激活SCG 1上的休眠BWP;进一步的,终端设备还可以通过PCell上的WUR信号接收SCG 1退出休眠指示,此时所述终端设备激活SCG 1上的非休眠BWP。类似的,终端设备可以通过PCell上的WUR信号接收SCG 2休眠指示,此时所述终端设备激活SCG 2上的休眠BWP。
图7是本申请实施例提供的指示SCG休眠或退出休眠的另一示意图。

实施例3:
本实施例中,终端设备通过WUR信号接收指示信息,所述指示信息用于指示第一SCell激活或去激活。
当终端设备具备的唤醒接收机时,所述终端设备可以接收一些与节能有关的唤醒信号,可以使所述终端设备关闭主收发机来实现节电。在主收发机关闭期间,所述终端设备是不能检测PDCCH的。
由于终端设备可能已经开启了唤醒接收机且关闭了主收发机,当需要激活或去激活所述第一SCell时,如果所述指示信息通过MAC CE承载,则需要接收PDCCH和PDSCH,即需要先通过唤醒信号唤醒UE的主收发机,再通过主收发机接收PDCCH和PDSCH,获得MAC CE。但是,这种先唤醒再接收的过程,会增加终端的功耗和传输时延
本实施例中,通过WUR信号接收所述指示信息,可以在只开启唤醒接收机的情况下接收所述指示信息,能够降低所述终端设备的功耗。即由于所述终端设备可能已经开启了唤醒接收机且关闭了主收发机,此时,所述终端设备可以通过WUR信号接收所述指示信息,从而激活或去激活所述第一SCell对应的下行和上行BWP。例如,激活的下行BWP的标识可以为网络设备配置的第一个激活下行BWP标识(firstActiveDownlinkBWP-Id)。例如,激活的上行BWP的标识可以为网络设备配置的第一个激活上行BWP标识(firstActiveUplinkBWP-Id)。
示例性地,所述终端设备可以在PCell或PCG上通过唤醒接收机接收所述指示信息,也可以在SCell或SCG上通过唤醒接收机接收所述指示信息,例如,所述终端设备可以在所述第一SCell上接收所述指示信息,也可以在不同于所述第一SCell的SCell上接收所述指示信息,本申请对此不作具体限定。
图8是本申请实施例提供的指示SCG休眠或退出休眠的示意图。
如图8所示,终端设备的PCell上开启唤醒接收机,终端设备的SCell 1上的BWP处于激活状态,终端设备的SCell 2上的BWP处于激活状态。终端设备可以通过PCell上的WUR信号接收SCell 1去激活指示,此时所述终端设备去激活SCell 1上相应的BWP;进一步的,终端设备还可以通过PCell上的WUR信号接收SCell 1激活指示,此时所述终端设备激活SCell 1上相应的BWP。类似的,终端设备可以通过PCell上的WUR信号接收SCell 2去激活指示,此时所述终端设备去激活SCell 2上相应的BWP。
需要说明的是,上述实施例1至实施例3可以相互结合,即所述指示信息可以同时指示第一SCell的休眠/退出休眠以及指示所述第一SCell的激活/去激活。
图9是本申请实施例提供的指示SCELL休眠或退出休眠的另一示意图。
如图9所示,终端设备的PCell上开启唤醒接收机,终端设备的SCell 1上的BWP处于激活状态,终端设备的SCell 2上的BWP处于激活状态。终端设备可以通过PCell上的WUR信号接收SCG 1休眠指示,此时所述终端设备激活SCG 1上的休眠BWP;进一步的,终端设备还可以通过PCell上的WUR信号接收SCG 1退出休眠指示,此时所述终端设备激活SCG 1上的非休眠BWP。类似的,所述终端设备可以通过PCell上的WUR信号接收SCell 2去激活指示,此时所述终端设备去激活SCell 2上相应的 BWP。
应当理解,图6至图9仅为本申请的示例,不应理解为对本申请的限制。
