一种通信方法及装置
相关申请的交叉引用
本申请要求在2020年03月10日提交中国国家知识产权局、申请号为202010162964.1、申请名称为“一种通信方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
支持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)架构的终端设备,可以具有两套收发系统。对于处于EN-DC架构下的终端设备,例如该终端设备的服务小区为长期演进(long term evolution,LTE)小区,如果该终端设备要对相应的新空口(new radio,NR)小区进行测量,则如果LTE基站识别出该终端设备仅做异系统测量(即,仅测量NR小区,而不测量其他的LTE小区),并且所要测量的频率与当前的服务小区的频率属于终端设备支持的EN-DC频率组合,则LTE基站可以不为终端设备配置测量间隔(gap)。从而终端设备既可以对NR小区进行测量,又能与服务小区通信,进而提高了传输效率。
但是终端设备在所支持的EN-DC频率组合下的LTE射频能力,可能比终端设备仅支持LTE系统时的LTE射频能力要低。例如终端设备共有4根接收天线(Rx),如果终端设备仅支持LTE频带(band),则这4根天线均可以用于接收LTE信号。但如果终端设备支持EN-DC频率组合,且终端设备在无gap的情况下对NR小区进行测量,则这4根天线中可能只有2根天线用于接收LTE信号,另外的2根天线需要用于在测量时接收NR信号。
可见,由于终端设备的测量过程,可能导致终端设备的LTE射频能力有所降低。此时终端设备可能为了保证当前LTE的服务质量,而不启动测量,导致无法进行NR频带的测量,无法找到好的EN-DC辅站。或者终端设备启动测量,由于在基站未知情况下终端设备自行降低了LTE射频能力,导致LTE服务可能出现误码。
发明内容
本申请实施例提供一种通信方法及装置,用于减小终端设备由于测量造成射频能力降低所带来的性能损失。
第一方面,提供第一种通信方法,该方法包括:确定终端设备的第一能力是否小于或等于所述终端设备的第二能力,所述第一能力为所述终端设备仅支持第一无线接入技术时工作在第一频率的能力,所述第二能力为所述终端设备在第一频率组合下对应于所述第一频率的能力,所述第一频率组合包括所述第一频率和第二频率,所述第一频率对应于所述第一无线接入技术,所述第二频率对应于第二无线接入技术;当所述第一能力小于或等于所述第二能力时,向所述终端设备发送第一消息,所述第一消息用于指示所述终端设备测 量所述第二频率,所述第一消息不包括第一测量间隔的配置,所述第一测量间隔用于测量所述第二频率。
该方法可由第一通信装置执行,第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置,例如芯片。示例性地,所述第一通信装置为网络设备,或者为设置在网络设备中的用于实现网络设备的功能的芯片,或者为用于实现网络设备的功能的其他部件。在下文的介绍过程中,以第一通信装置是网络设备为例。
在本申请实施例中,可以确定终端设备的第一能力是否小于或等于终端设备的第二能力,终端设备的能力例如包括终端设备的射频能力,例如,是确定终端设备仅支持LTE系统时的LTE射频能力是否小于或等于终端设备在EN-DC频率组合下的LTE射频能力,如果第一能力小于或等于终端设备的第二能力,表明终端设备在EN-DC频率组合下,LTE射频能力不会有损失,因此可以不为终端设备配置测量间隔,从而终端设备既可以对第二频率进行测量,又能在第一频率与网络设备等设备通信,可以提高传输效率。在确定LTE射频能力不会有损失的情况下才不为终端设备配置测量间隔,终端设备可以正常完成测量,从而能够找到较好的EN-DC辅站。而且终端设备也无需在网络设备未知的情况下自行降低LTE射频能力,减小了LTE服务出现误码的概率。
结合第一方面,在第一方面的第一种可能的实施方式中,所述终端设备是工作在所述第一频率时测量所述第二频率。
因为网络设备比较的是第一能力和第二能力,第一能力和第二能力都是对应于第一频率的,因此如果终端设备要测量第二频率,终端设备的工作频率,或者说终端设备的服务小区的频率,需要是第一频率,这样终端设备才能正常完成对第二频率的测量。
结合第一方面或第一方面的第一种可能的实施方式,在第一方面的第二种可能的实施方式中,所述方法还包括:
当所述第一能力大于所述第二能力时,向所述终端设备发送第二消息,所述第二消息用于指示所述终端设备测量所述第二频率,所述第二消息包括所述第一测量间隔的配置。
如果第一能力大于第二能力,那么,如果终端设备在第一频率采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用一种方法,即,可以继续配置终端设备工作在第一频率时测量第二频率,但是会为终端设备配置第一gap,终端设备在第一gap中测量第二频率。这样,终端设备工作在第一频率时,不会同时对第二频率进行测量以及在第一频率与网络设备通信,在第一gap之外,终端设备可以通过第一能力在第一频率与网络设备等通信,不会使得终端设备对应于第一无线接入技术的通信性能有所损失,而在第一gap之内,终端设备又可以对第二频率进行测量。通过这种方式,既可以满足终端设备的测量需求,又不会使得终端设备对应于第一无线接入技术的能力受损。
结合第一方面或第一方面的第一种可能的实施方式,在第一方面的第三种可能的实施方式中,所述方法还包括:
当所述第一能力大于所述第二能力时,配置所述终端设备工作在所述第一频率的第一通信参数,以按照第三能力调度所述终端设备在所述第一频率的通信,所述第三能力小于或等于所述第二能力;
向所述终端设备发送第三消息,所述第三消息用于指示所述终端设备测量所述第二频率,所述第三消息不包括第一测量间隔的配置,所述第一测量间隔用于测量所述第二频率。
如果第一能力大于第二能力,那么,如果终端设备在第一频率采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用另一种方法,例如,网络设备为该终端设备配置工作在第一频率的通信参数为第一通信参数,第一通信参数对应终端设备的第三能力,也就是说,如果终端设备被配置了第一通信参数,则终端设备就以第三能力工作,或者说,第一通信参数是用于配置终端设备的能力为第三能力的通信参数。因此,在配置第一通信参数后,网络设备可以按照第三能力调度该终端设备在第一频率的通信,终端设备也按照第三能力在第一频率与网络设备通信,且第三能力小于或等于第二能力。在这种情况下,是网络设备为终端设备配置的第三能力,因此第三能力是网络设备已知的。网络设备在为终端设备调度第一频率的通信时,也会按照第三能力来调度,使得网络设备的调度与终端设备的实际能力相匹配,终端设备能够正常按照第三能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
结合第一方面的第三种可能的实施方式,在第一方面的第四种可能的实施方式中,所述第三消息还包括所述第一通信参数,所述第一通信参数为用于配置所述终端设备的能力为所述第三能力的通信参数。
第三消息可以包括第一通信参数,或者第三消息可以指示第三能力。从而终端设备在接收第三消息后也能够获知被配置了工作在第一频率的能力为第三能力,则终端设备可以按照第三能力在第一频率进行通信。
结合第一方面或第一方面的第一种可能的实施方式,在第一方面的第五种可能的实施方式中,所述方法还包括:
当所述第一能力大于所述第二能力时,确定所述终端设备工作在所述第一频率的第二通信参数,以按照所述第二能力调度所述终端设备在所述第一频率的通信;
向所述终端设备发送第四消息,所述第四消息用于指示所述终端设备测量所述第二频率,所述第四消息不包括第一测量间隔的配置,所述第一测量间隔用于测量所述第二频率。
如果第一能力大于第二能力,那么,如果终端设备在第一频率采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用另一种方法,例如,网络设备配置该终端设备工作在第一频率的通信参数为第二通信参数,第二通信参数对应终端设备的第二能力,也就是说,如果终端设备被配置了第二通信参数,则终端设备就以第二能力工作,或者说,第二通信参数是用于配置终端设备的能力为第二能力的通信参数。而此时网络设备和终端设备都明确终端设备在第一频率组合下对应于第一频率的能力为第二能力,因此网络设备无需再为终端设备配置第二通信参数,只需按第二能力调度终端设备在第一频率的通信即可。
结合第一方面或第一方面的第一种可能的实施方式,在第一方面的第六种可能的实施方式中,所述方法还包括:
当所述第一能力大于所述第二能力时,配置所述终端设备在第二测量间隔内工作在所述第一频率的第三通信参数,以在所述第二测量间隔内按照第四能力调度所述终端设备在所述第一频率的通信,所述第四能力小于或等于所述第一能力,所述第二测量间隔用于测量所述第二频率;
向所述终端设备发送第五消息,所述第五消息用于指示所述终端设备测量所述第二频率,所述第五消息包括所述第二测量间隔的配置,所述第二测量间隔用于测量所述第二频 率。
如果第一能力大于第二能力,那么,如果终端设备在第一频率采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用再一种方法。例如,网络设备确定该终端设备在第二gap内工作在第一频率的通信参数为第三通信参数,第三通信参数对应终端设备的第四能力,也就是说,如果终端设备被配置了第三通信参数,则终端设备就以第四能力工作,或者说,第三通信参数是用于配置终端设备的能力为第四能力的通信参数。第四能力小于或等于第一能力。在配置第二通信参数后,网络设备在第二gap内可以按照第四能力调度该终端设备在第一频率的通信,在第二gap内终端设备也按照第四能力在第一频率与网络设备通信,且第四能力小于或等于第一能力。在这种情况下,是网络设备为终端设备配置的第四能力,因此第四能力是网络设备已知的。网络设备在第二gap内为终端设备调度第一频率的通信时,也会按照第四能力来调度,使得网络设备的调度与终端设备的实际能力相匹配,终端设备在第二gap内能够正常按照第四能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
结合第一方面的第六种可能的实施方式,在第一方面的第七种可能的实施方式中,所述第五消息还包括所述第三通信参数,所述第三通信参数为用于配置所述终端设备的能力为所述第四能力的通信参数。
第五消息可以包括第三通信参数,或者第五消息可以指示第四能力。从而终端设备在接收第五消息后也能够获知在第二gap内被配置了工作在第一频率的能力为第四能力,则终端设备在第二gap内可以按照第四能力在第一频率进行通信。
结合第一方面或第一方面的第一种可能的实施方式,在第一方面的第八种可能的实施方式中,所述方法还包括:
当所述第一能力大于所述第二能力时,确定所述终端设备在第二测量间隔内工作在所述第一频率的第四通信参数,以在所述第二测量间隔内按照所述第二能力调度所述终端设备在所述第一频率的通信;
向所述终端设备发送第六消息,所述第六消息用于指示所述终端设备测量所述第二频率,所述第六消息包括第二测量间隔的配置,所述第二测量间隔用于测量所述第二频率。
如果第一能力大于第二能力,那么,如果终端设备在第一频率采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用又一种方法。例如,网络设备确定该终端设备在第二gap内工作在第一频率的通信参数为第四通信参数,第四通信参数对应终端设备的第二能力,也就是说,如果终端设备被配置了第四通信参数,则终端设备就以第二能力工作,或者说,第四通信参数是用于配置终端设备的能力为第二能力的通信参数。而此时网络设备和终端设备都明确终端设备在第一频率组合下对应于第一频率的能力为第二能力,因此网络设备无需再为终端设备配置第四通信参数,只需按第二能力调度终端设备在第一频率的通信即可,可以节省信令开销。
结合第一方面或第一方面的第一种可能的实施方式至第一方面的第八种可能的实施方式中的任一种可能的实施方式,在第一方面的第九种可能的实施方式中,
所述第一频率组合是所述终端设备支持的频率组合;或,
所述方法还包括:确定所述第一频率和第三频率对所述终端设备处于激活状态,且所 述终端设备支持的频率组合中不包括所述第一频率、所述第二频率和所述第三频率构成的频率组合,则去激活所述第三频率,得到所述第一频率组合,所述第三频率对应于所述第一无线接入技术,所述第一频率组合是所述终端设备支持的频率组合。
如果终端设备未被配置载波聚合,则该终端设备的服务小区只有一个,例如只有第一频率,则终端设备只需确定第一频率和第二频率构成的频率组合是否是终端设备所支持的频率组合即可,且本申请实施例以第一频率组合是终端设备所支持的频率组合为例。而如果该终端设备被配置了载波聚合,则该终端设备的服务小区就可能有多个,例如该终端设备的服务小区包括主小区和辅小区,主小区可能有一个,辅小区可能有一个或多个。在这种情况下,如果对于终端设备来说,处于激活状态的服务小区的个数大于或等于2,则网络设备最初确定的就不只是第一频率和第二频率,而是还包括一个或多个频率,这一个或多个频率均对应于第一无线接入技术。网络设备如果确定第一频率和第三频率对终端设备处于激活状态,则可以确定第一频率、第二频率和第三频率构成的频率组合是否是该终端设备支持的频率组合;如果该终端设备支持的频率组合中不包括第一频率、第二频率和第三频率构成的频率组合,则网络设备可以去激活第三频率,得到包括第一频率和第二频率的第一频率组合。通过这种方式使得终端设备尽量可以完成对第二频率的测量。
结合第一方面或第一方面的第一种可能的实施方式至第一方面的第九种可能的实施方式中的任一种可能的实施方式,在第一方面的第十种可能的实施方式中,确定终端设备的第一能力是否小于或等于所述终端设备的第二能力,包括:

2)网络设备,例如包括接入网(access network,AN)设备,例如基站(例如,接入点),可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备,或者例如,一种车到一切(vehicle-to-everything,V2X)技术中的网络设备为路侧单元(road side unit,RSU)。基站可用于将收到的空中帧与IP分组进行相互转换,作为终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体,可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如,网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括第五代移动通信技术(the 5th generation,5G)NR系统(也简称为NR系统)中的下一代节点B(next generation node B,gNB)或者也可以包括云接入网(cloud radio access network,Cloud RAN)系统中的集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU),本申请实施例并不限定。
网络设备还可以包括核心网设备,核心网设备例如包括访问和移动管理功能(access and mobility management function,AMF)或用户面功能(user plane function,UPF)等。因为本申请实施例主要涉及的是接入网设备,因此在后文中,如无特殊说明,则所述的网络设备均是指接入网设备。

3)多无线接入技术双连接(multi-RAT dual connectivity,MR-DC),在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5G NR系统和LTE系统,终端设备也支持同时接入到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。当然随着系统的演进,未来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的终端设备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MR-DC。
4)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。

前文介绍了本申请实施例所涉及到的一些名词概念,下面介绍本申请实施例涉及的技术特征。
在LTE系统中,基站间在布网时,可能无法对齐时间。而在为LTE基站配置DC架构之后,LTE主基站会给终端设备配置gap,终端设备在gap内测量来自LTE辅基站的同步信号。但是LTE主基站和LTE辅基站的时间可能未对齐,导致LTE主基站所配置的gap与LTE辅基站的时间不对齐,可能使得LTE主基站配置的gap无法完全覆盖或者无法覆盖来自LTE辅基站的同步信号,这可能导致终端设备得到的测量结果不够准确,或者可能导致终端设备无法完成测量。为此,引入了系统帧号和子帧定时差(SFN and subframe timing difference,SSTD)测量,具有SSTD测量能力的终端设备,可以在无需配置gap的情况下对LTE辅基站的小区进行测量,从而得到LTE辅基站的小区与LTE主基站的小区之间的时间差。终端设备将该时间差发送给LTE主基站,从而LTE主基站可以根据该时间差来为终端设备配置gap。
在NR系统中,由于EN-DC架构的布网,LTE主基站与NR辅基站也同样存在时间无法对齐的问题。由于终端设备是靠NR辅基站周期性广播的同步/物理广播信道块(synchronization/physical broadcast channel block,SSB)来测量辅基站,当前,LTE主基站需要给终端设备配置gap,来让终端设备在gap内接收来自辅基站的SSB。但是由于LTE主基站和NR辅基站的时间无法对齐,LTE主基站所配置的gap有可能无法包含NR辅基 站的SSB,导致终端设备无法在gap内接收来自NR辅基站的SSB,从而无法完成测量。例如可参考图1,异系统(例如对于LTE系统来说,NR系统就是异系统)的测量周期例如为40ms,其中gap的时长为6ms,但是来自NR辅基站的小区的SSB却落在了剩余的34ms内,因此gap无法覆盖NR辅基站的小区的SSB,从而终端设备无法完成测量。
目前,为了解决主基站不知道所添加的辅基站与主基站之间的时间差的问题,引入了SFTD测量,与SSTD测量的区别在于,基站可以配置具有SFTD测量能力的终端设备,在辅基站尚未添加时,就测量主基站和可能的辅基站之间的时间差,进而将测量的时间差上报给主基站,协助主基站在给为该终端设备或小区内的其他终端设备配置gap时,可以参考该时间差,尽量使得所配置的gap能覆盖辅基站的SSB,保证终端设备可以在gap内检测到来自辅基站的SSB。
可以看到,具有SFTD测量能力的终端设备在未配置NR辅站时对其他NR小区进行测量时间差时,是可以不配置gap的,而是可以直接进行测量时间差。但当前,如果主基站要配置终端设备测量潜在辅基站的小区的信号质量,例如,LTE基站要配置终端设备测量NR基站的小区,则依然会为终端设备配置gap,终端设备在gap内进行测量。在gap对应的时间段内,终端设备无法与终端设备的服务小区通信,也就是说,主基站所配置的gap实际上是占用了终端设备和终端设备的服务小区之间的传输时间。然而根据前文的介绍可知,对于具备SFTD能力的终端设备来说,在对其他小区进行测量时,无需gap就能完成测量。那么基站又为这样的终端设备配置gap,造成了传输资源的浪费。
由于有些终端设备可能具备两套收发系统,因此为了节省传输资源,目前有优化实现的方式,网络设备对于支持EN-DC架构的终端设备,例如该终端设备的服务小区为LTE小区,并且此时还未添加NR辅站,如果该终端设备要对相应的NR小区进行测量,则如果LTE基站识别出该终端设备仅做异系统测量(即,仅测量NR小区,而不测量其他的LTE小区),并且所要测量的频率与当前的服务小区的频率属于终端设备支持的EN-DC频率组合(即说明终端设备可以支持同时在LTE服务小区所在频带和需测量的NR辅小区所在的频带上同时收发),则LTE基站可以不为终端设备配置gap,终端设备可以在无gap的情况下对NR小区进行测量。从而终端设备既可以对NR小区进行测量,又能与服务小区通信,进而提高了传输效率。
但是终端设备在所支持的EN-DC频率组合下的LTE射频能力,可能比终端设备仅支持LTE系统时的LTE射频能力要低。例如终端设备共有4根接收天线,如果终端设备仅支持LTE频带,则这4根天线均可以用于接收LTE信号。但如果终端设备支持某EN-DC频率组合,且终端设备在无gap的情况下对NR小区进行测量时,这4根天线中可能只有2根天线用于接收LTE信号,另外的2根天线需要用于在测量时接收NR信号。
可见,由于终端设备的测量过程,可能导致终端设备的LTE射频能力有所降低。如果终端设备为了不损害LTE信号的接收而不对NR小区进行测量,则导致终端设备无法获得对NR小区的测量结果;或者,如果终端设备在无gap情况下对NR小区进行测量,且也正常接收LTE信号,则因为终端设备在测量NR小区时的LTE射频能力受到限制,只能以较低的射频能力接收LTE信号。但由于LTE基站之前为终端设备配置的是较高的LTE射频能力,因此LTE基站仍然会以较高的能力调度终端设备,从而可能导致出现信令或数据误码的情况。
鉴于此,提供本申请实施例的技术方案。在本申请实施例中,可以确定终端设备的第 一能力是否小于或等于终端设备的第二能力,终端设备的能力例如包括终端设备的射频能力,例如,是确定终端设备仅支持LTE系统时的LTE射频能力是否小于或等于终端设备在EN-DC频率组合下的LTE射频能力,如果第一能力小于或等于终端设备的第二能力,表明终端设备在EN-DC频率组合下,LTE射频能力不会有损失,因此可以不为终端设备配置测量间隔,从而终端设备工作在第一频率时,既可以对第二频率进行测量,又能在第一频率与网络设备通信,可以提高传输效率。在确定LTE射频能力不会有损失的情况下才不为终端设备配置测量间隔,终端设备可以正常完成测量,从而能够找到较好的EN-DC辅站。而且终端设备也无需在网络设备未知的情况下自行降低LTE射频能力,减小了LTE服务出现误码的概率。
下面介绍本申请实施例所应用的网络架构。
请参考图2,为本申请实施例所应用的一种网络架构。
图2包括两个网络设备和终端设备。这两个网络设备之间是双连接的架构,其中的网络设备1例如为主网络设备,其中的网络设备2例如为辅网络设备。终端设备可以和这两个网络设备通信。当然图2中的终端设备的数量只是举例,在实际应用中,网络设备可以为多个终端设备提供服务。
图2中的网络设备例如为接入网设备,例如基站。其中,接入网设备在不同的系统对应不同的设备,例如在4G系统中可以对应eNB,在5G系统中对应5G中的接入网设备,例如gNB,或为后续演进的通信系统中的接入网设备。例如,图2为EN-DC架构,则网络设备1为LTE网络设备,网络设备2为NR网络设备;或者,图2为NE-DC架构,则网络设备1为NR网络设备,网络设备2为LTE网络设备,等等。
接下来结合附图介绍本申请实施例提供的技术方案。
在终端设备刚开机时,会向网络设备上报该终端设备的能力,或者,在终端设备切换到某个新的小区时,网络设备会请求终端设备上报终端设备的能力。当用户准备通过终端设备执行业务时,例如用户要使用终端设备上网时,为该终端设备提供服务的网络设备(此时认为是主网络设备)可能希望给该终端设备增加辅网络设备,形成DC架构,以提高吞吐量,增加网络速度。在DC架构下,主网络设备会配置终端设备在gap内测量其他小区,而gap会占用终端设备和终端设备的服务小区之间的传输时间。或者,例如该终端设备的服务小区为LTE小区,如果该终端设备要对相应的NR小区进行测量,则如果LTE基站识别出该终端设备仅做异系统测量(即,仅测量NR小区,而不测量其他的LTE小区),并且所要测量的频率与当前的服务小区的频率属于终端设备支持的EN-DC频率组合,则LTE基站可以不为终端设备配置gap,终端设备可以在无gap的情况下对NR小区进行测量。但是终端设备在所支持的EN-DC频率组合下的LTE射频能力,可能比终端设备仅支持LTE系统时的LTE射频能力要低。也就是说,由于终端设备的测量过程,导致终端设备的LTE射频能力有所降低。在这种场景下,就可以采用本申请实施例提供的方案,减少终端设备由于测量带来的LTE射频能力降低造成的性能损失。
本申请实施例提供第一种通信方法,请参见图3,为该方法的流程图。在下文的介绍过程中,以该方法应用于图2所示的网络架构为例。
如果将本申请实施例应用在图2所示的网络架构,则下文中所述的终端设备可以实现图2所示的网络架构中的终端设备的功能,下文中所述的网络设备可以实现图2所示的网络架构中的网络设备1或网络设备2的功能。
S31、终端设备向网络设备发送能力信息,网络设备接收来自终端设备的该能力信息。
能力信息例如可以包括在UE能力信息(UE capability information)消息中发送给网络设备,UE能力信息消息可以是无线资源控制(radio resource control,RRC)消息。或者能力信息也可以包括在其他的RRC消息中发送给网络设备,或者能力信息也可以包括在除了RRC消息外的其他消息中发送给网络设备,例如可以包括在物理层消息中发送给网络设备,例如该物理层消息可以承载在物理上行控制信道(physical uplink control channel,PUCCH)或物理上行共享信道(physical uplink shared channel,PUSCH)上;或者,能力信息也可以包括在媒体接入控制(media access control,MAC)控制元素(control element,CE)中发送给网络设备,等等。
该能力信息包括该终端设备在不同频率及频率组合下的能力,例如包括该终端设备在第一无线接入技术对应的频率组合下的各频率的能力,以及包括该终端设备在第一无线接入技术和第二无线接入技术对应的频率组合下的各频率的能力。例如,该能力信息可以指示该终端设备在仅支持第一无线接入技术时工作在N个频率下的能力,以及指示该终端设备在所支持的至少一个频率组合中的每个频率组合下对应于第三频率的能力,N个频率包括第一频率,所述的每个频率组合包括第三频率和第四频率,第三频率对应于第一无线接入技术。N为大于或等于1的整数。本申请实施例中所述的终端设备的能力,例如为终端设备的射频能力,终端设备的射频能力例如包括终端设备支持的多输入多输出(multiple input multiple output,MIMO)层数、探测参考信号(sounding reference signal,SRS)端口数或终端设备支持的天线端口数中的一项或多项。例如,在后文中将要介绍的终端设备的第一能力,可以包括该终端设备的MIMO层数、SRS端口数或该终端设备支持的天线端口数中的一项或多项;同理,终端设备的第二能力,可以包括该终端设备的MIMO层数、SRS端口数或该终端设备支持的天线端口数中的一项或多项。
该终端设备可以工作在双连接的架构下,则该终端设备可以支持第一无线接入技术和第二无线接入技术。例如,第一无线接入技术为LTE技术,第二无线接入技术为NR技术;或者,第一无线接入技术为NR技术,第二无线接入技术为LTE技术,或者,第一无线接入技术或第二无线接入技术也可以是其他的技术。以第一无线接入技术是LTE技术、第二无线接入技术是NR技术为例。例如,如果终端设备仅工作在LTE系统下,不工作在NR系统下,则终端设备在LTE系统下可以支持N个频率,这N个频率可以是终端设备在LTE系统下支持的全部频率或部分频率。其中,终端设备工作在这N个频率的不同频率时,终端设备的能力可能相同,也可能不同。而该能力信息就可以指示这N个频率对应的能力,或者说,指示终端设备对应于这N个频率的N个能力。
而如果终端设备既工作在第一无线接入技术下也工作在第二无线接入技术下,那么终端设备可以支持M个频率组合,M为大于或等于1的整数。这M个频率组合中的每个频率组合,可以包括第一无线接入技术的频率和第二无线接入技术的频率,例如每个频率组合包括第三频率和第四频率,第三频率是第一无线接入技术对应的频率,第四频率是第二无线接入技术对应的频率。例如终端设备工作在EN-DC下,即,终端设备既工作在LTE系统也工作在NR系统,那么终端设备可以支持M个频率组合,M个频率组合中的每个频率组合可以包括LTE频率和NR频率,终端设备在所支持的这些频率组合下能够正常工作。终端设备工作在所支持的一个频率组合下,对于该频率组合包括的LTE频率和NR频率,终端设备都有对应的能力。例如终端设备支持的频率组合1包括LTE频率1和NR频率1, 则如果说明终端设备支持同时工作在LTE系统中的LTE频率1下和在NR系统中的NR频率1下。另外,如果终端设备工作在频率组合1,则对于频率组合1中的LTE频率1,终端设备的能力为能力1,对于频率组合1中的NR频率1,终端设备的能力为能力2。该能力信息可以指示终端设备在所支持的至少一个频率组合中的每个频率组合下对应于第三频率的能力,例如M个频率组合是终端设备支持的全部频率组合,则至少一个频率组合可以包括M个组合中的全部频率组合或部分频率组合。如果第一无线接入技术为LTE技术,第二无线接入技术为NR技术,则该能力信息可以指示终端设备在所支持的至少一个频率组合中的每个频率组合下对应于LTE频率的能力。
以第一无线接入技术为LTE技术,第二无线接入技术为NR技术为例,相当于,该能力信息既包括终端设备仅工作在LTE系统下的能力,也包括终端设备工作在LTE系统和NR系统时对应于LTE系统的能力。从而网络设备接收该能力信息后,就可以确定终端设备仅工作在LTE系统下的能力,也可以确定终端设备工作在LTE系统和NR系统时对应于LTE系统的能力。
S32、终端设备向网络设备发送指示信息,网络设备接收来自终端设备的指示信息。
指示信息例如可以包括在UE capability information消息中发送给网络设备。或者指示信息也可以包括在其他的RRC消息中发送给网络设备,或者指示信息也可以包括在除了RRC消息外的其他消息中发送给网络设备,例如可以包括在物理层消息中发送给网络设备,例如该物理层消息可以承载在PUCCH或PUSCH上;或者,指示信息也可以包括在MAC CE中发送给网络设备,等等。
该指示信息用于指示一个或多个频率组合。其中,终端设备在这一个或多个频率组合中的每个频率组合下,对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,或,终端设备在这一个或多个频率组合中的每个频率组合下,对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。所述的每个频率组合包括第五频率和第六频率,第五频率对应于第一无线接入技术,第六频率对应于第二无线接入技术。其中,该终端设备仅支持第一无线接入技术时,可能只工作在第五频率,或者也可能工作在包含了第五频率的频率组合下,该频率组合所包括的各个频率均是第一无线接入技术对应的频率。也就是说,该终端设备仅支持第一无线接入技术时,可能只工作在第五频率,或者也可能工作在多个频率,这多个频率包括第五频率。那么,本申请实施例所述的,终端设备仅支持第一无线接入技术时工作在第五频率的能力,可以是指该终端设备仅支持第一无线接入技术,且仅工作在第五频率时的能力,或者,也可以是指,该终端设备仅支持第一无线接入技术,且工作在包含了第五频率的频率组合下时对应于第五频率的能力。后文中与此类似的内容,其理解也是一致的,因此在后文中不再多赘述。
在前文介绍了,如果终端设备既工作在第一无线接入技术下也工作在第二无线接入技术下,那么终端设备可以支持M个频率组合。这M个频率组合中的每个频率组合,可以包括第一无线接入技术的频率和第二无线接入技术的频率。对于一个频率组合来说,终端设备工作在该频率组合下时,终端设备对应于该频率组合包括的第三频率的能力,终端设备是能够确定的,而如果终端设备没有工作在该频率组合下,而是仅工作在第一无线接入技术下,则终端设备对应于第三频率的能力,终端设备也是能够确定的。因此在本申请实施例中,终端设备可以从M个频率组合中确定一个或多个频率组合,这一个或多个频率组 合可以包括M个频率组合中的全部组合或部分组合。为了与M个频率组合中的其他频率组合相区分,将这一个或多个频率组合中的每个频率组合中,对应于第一无线接入技术的频率称为第五频率,对应于第二无线接入技术的频率称为第六频率。即,这一个或多个频率组合中的每个频率组合包括第五频率和第六频率,第五频率是第一无线接入技术对应的频率,第六频率是第二无线接入技术对应的频率。其中,第三频率、第四频率、第五频率及第六频率等名称,都只是泛指,例如第三频率和第五频率均是泛指频率组合下对应于第一无线接入技术的频率,第四频率和第六频率均是泛指频率组合下对应于第二无线接入技术的频率。
例如,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力;或者,终端设备在这一个或多个频率组合中的每个频率组合下,对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力;或者,终端设备在这一个或多个频率组合中的部分频率组合中的每个频率组合下,对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,以及,终端设备在这一个或多个频率组合中剩余的部分频率组合中的每个频率组合下,对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。
例如,终端设备工作在EN-DC下,即,终端设备既工作在LTE系统也工作在NR系统,那么终端设备可以支持M个频率组合,其中的每个频率组合可以包括LTE频率和NR频率,终端设备在所支持的这些频率组合下能够正常工作。例如终端设备支持的频率组合1包括LTE频率1和NR频率1,则终端设备在LTE系统可以同时工作在LTE频率1下和NR系统中的NR频率1下。另外,如果终端设备工作在频率组合1,则对于频率组合1中的LTE频率1,终端设备的能力为能力1,对于频率组合1中的NR频率1,终端设备的能力为能力2。而如果终端设备仅工作在LTE系统下,则终端设备工作在LTE频率1时的能力为能力3。
则终端设备可以确定能力1和能力3的大小关系。如果能力1等于能力3,且如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以包括在所述的一个或多个频率组合内,而如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以不包括在所述的一个或多个频率组合内;
或者,如果能力1大于能力3,且如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以包括在所述的一个或多个频率组合内,而如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以不包括在所述的一个或多个频率组合内;
或者,如果能力1小于能力3,且如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,小于或等于该终端设 备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以包括在所述的一个或多个频率组合内,而如果所述的一个或多个频率组合满足,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则频率组合1可以不包括在所述的一个或多个频率组合内。
终端设备的能力可以通过天线数、天线端口数、MIMO层数、或SRS端口数中的一种或多种射频特性来描述。以终端设备的能力通过终端设备支持的天线的数量来表征为例。例如能力1对应于2根天线,能力3对应于3根天线,则能力1小于能力3。
其中,指示信息可以只需指示一个或多个频率组合即可,无需指示具体的能力。例如指示信息所指示的这一个或多个频率组合为,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,则该指示信息只需指示这一个或多个频率组合(例如指示这一个或多个频率组合的标识),无需指示这一个或多个频率组合具体对应的能力。而S31中的能力信息,指示的是具体的能力,可以认为该能力信息包括具体的能力。
其中,S31和S32都是可选的步骤,不是必须执行的,因此在图3中用虚线表示。并且,S31和S32可以只执行其中一个即可,不必两个步骤均执行。如果只执行S31,则网络设备能够获得较为详细的能力信息,而如果只执行S31,则指示信息的信息量显然小于能力信息的信息量,则有助于节省信令开销。或者,S31和S32也可以均执行,例如终端设备可以将终端设备的实际的能力信息发送给网络设备,网络设备可以根据该能力信息对终端设备进行调度等。另外终端设备还可以向网络设备发送指示信息,从而可供网络设备确定终端设备的能力,则网络设备在确定终端设备的能力时无需在该终端设备的能力信息中查询,有助于简化网络设备的操作过程。例如,终端设备也可以将实际的能力信息以及指示信息通过同一条消息发送给网络设备,并针对每个频率组合进行指示,用于区分哪些EN-DC频率组合下,LTE的频率的能力小于或大于单独工作在LTE频率下的能力。
S33、网络设备确定终端设备的第一能力是否小于或等于该终端设备的第二能力。
其中,第一能力表示该终端设备仅支持第一无线接入技术时,工作在第一频率的能力。第二能力表示该终端设备工作在第一频率组合下时,对应于第一频率的能力。其中,第一频率组合可以是终端设备支持的M个频率组合中的一个。第一频率组合包括第一频率和第二频率,第一频率对应于第一无线接入技术,第二频率对应于第二无线接入技术。第一频率组合所包括的第一频率可以是前文所述的第一频率组合所包括的第三频率,第一频率组合所包括的第二频率可以是前文所述的第一频率组合所包括的第四频率。
例如,终端设备当前的服务小区的频率为第一频率,网络设备要配置终端设备工作在第一频率时对第二频率进行测量,则网络设备在执行S33之前,可以先确定第一频率组合是否属于终端设备所支持的频率组合。其中,第一频率是终端设备的工作频率,或者说终端设备的服务小区的频率为第一频率。例如网络设备已通过S31接收了该终端设备的能力信息,则网络设备可以根据该能力信息确定终端设备所支持的频率组合,从而网络设备可以确定第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以执行S33;而如果第一频率组合不是终端设备所支持的频率组合,则可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备 配置gap,例如称为第三gap,终端设备在第一频率下可以通过第三gap对第二频率进行测量,等等。本申请实施例以第一频率组合是终端设备所支持的频率组合为例。
作为一种可选的实施方式,网络设备可以根据S31中接收的能力信息确定第一能力是否小于或等于第二能力。该能力信息可以指示该终端设备在仅支持第一无线接入技术时工作在N个频率下的N个能力,以及指示该终端设备在所支持的至少一个频率组合中的每个频率组合下对应于第三频率的能力,因此,该能力信息可以指示第一能力,也可以指示第二能力。从而网络设备根据该能力信息就可以确定第一能力是否小于或等于第二能力。例如,该能力信息指示,第一能力为2根天线,第二能力为4根天线,则网络设备确定第一能力小于第二能力;或者,该能力信息指示,第一能力为2根天线,第二能力为2根天线,则网络设备确定第一能力等于第二能力;或者,该能力信息指示,第一能力为2根天线,第二能力为1根天线,则网络设备确定第一能力大于第二能力。又例如,该能力信息指示,第一能力为MIMO层数为2,第二能力为MIMO层数为4,则网络设备确定第一能力小于第二能力;或者,该能力信息指示,第一能力为MIMO层数为2,第二能力为MIMO层数为2,则网络设备确定第一能力等于第二能力;或者,该能力信息指示,第一能力为MIMO层数为2,第二能力为MIMO层数为1,则网络设备确定第一能力大于第二能力。
或者,作为另一种可选的实施方式,网络设备也可以根据S32中接收的指示信息确定第一能力是否小于或等于第二能力。该指示信息指示了一个或多个频率组合,例如,终端设备在这一个或多个频率组合中的每个频率组合下对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。那么,终端设备可以确定第一频率组合是否包括在这一个或多个频率组合内,如果所述的一个或多个频率组合包括第一频率组合,则网络设备可以确定第一能力小于或等于第二能力,而如果所述的一个或多个频率组合包括第一频率组合,则网络设备可以确定第一能力大于第二能力。
或者,终端设备在这一个或多个频率组合中的每个频率组合下,对应于第五频率的能力,小于或等于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。那么,终端设备可以确定第一频率组合是否包括在这一个或多个频率组合内,如果所述的一个或多个频率组合包括第一频率组合,则网络设备可以确定第一能力大于或等于第二能力,而如果所述的一个或多个频率组合包括第一频率组合,则网络设备可以确定第一能力小于或等于第二能力。
或者,终端设备在这一个或多个频率组合中的部分频率组合中的每个频率组合下,对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力,以及,终端设备在这一个或多个频率组合中剩余的部分频率组合中的每个频率组合下,对应于第五频率的能力,小于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。可以理解为,指示信息包括第一子信息和第二子信息,第一子信息指示K1个频率组合,终端设备在K1个频率组合中的每个频率组合下,对应于第五频率的能力,大于该终端设备仅支持第一无线接入技术时工作在第五频率的能力;第二子信息指示K2个频率组合,终端设备在K2个频率组合中的每个频率组合下,对应于第五频率的能力,小于该终端设备仅支持第一无线接入技术时工作在第五频率的能力。K1和K2均为大于或等于0的整数。那么,终端设备可以确定第一频率组合是否包括在K1个频率组合内,如果K1个频率组合包括第一频率组合,则网络设备可以确定第一能力小于或等于第二能力;而如果K1个频率组合不包括第一频率组合,终端设备可以确定第一频率组合是否包括在K2个频率组合 内,如果K2个频率组合包括第一频率组合,则网络设备可以确定第一能力大于第二能力。
或者,网络设备要确定第一能力是否小于或等于第二能力,也可以既不根据能力信息确定也不根据指示信息确定,而是通过其他方式确定,本申请实施例对此不作限制。
S34、当第一能力小于或等于第二能力时,网络设备向终端设备发送第一消息,终端设备接收来自网络设备的第一消息。第一消息可以指示测量第二频率,且,第一消息不包括第一测量间隔的配置,第一测量间隔用于测量第二频率。
第一消息例如为物理层消息,例如第一消息可以承载在PUCCH或PUSCH上;或者,第一消息也可以是MAC CE;或者,第一消息还可以是RRC消息,等等。
在本文中所述的,终端设备测量第二频率,可以是指终端设备测量第二频率下的小区,或者说测量频率为第二频率的小区。第二频率下可能有多个小区,终端设备可以对这多个小区中的部分小区或全部小区进行测量。终端设备对一个小区进行测量,例如是接收来自该小区的系统消息,并根据系统消息进行测量。
也就是说,如果第一能力小于或等于第二能力,表明终端设备工作在第一频率组合下时,终端设备对应于第一无线接入技术的能力不会有损失,因此网络设备可以配置终端设备正常测量第二频率。在这种情况下,网络设备无需为终端设备配置gap,终端设备在无gap的情况下对第二频率进行测量即可。则终端设备工作在第一频率时,既可以对第二频率进行测量,也可以在第一频率与网络设备进行通信,有助于提高传输效率,且终端设备的能力也能得到充分利用。
其中,因为网络设备在对终端设备的能力进行判断时,依据的是终端设备对应于第一频率的能力和终端设备对应于第一频率组合中的第一频率的能力,因此在本申请实施例中终端设备在根据网络设备的指示对第二频率进行测量时,需要工作在第一频率下,否则如果终端设备工作在其他频率时对第二频率进行测量,则已经不适用于网络设备的判断条件,可能会导致测量出现问题。例如终端设备工作在第三频率下时对第二频率进行测量,第三频率和第二频率构成的频率组合是终端设备支持的频率组合,第三频率对应于第一无线接入技术。终端设备在该频率组合下对应于第三频率的能力,可能比终端设备仅支持第一无线接入技术时工作在第三频率的能力要低。则终端设备可能为了保证当前LTE的服务质量,而不启动测量,导致无法进行NR频带的测量,无法找到好的EN-DC辅站。或者终端设备启动测量,由于在基站未知情况下终端设备自行降低了LTE射频能力,导致LTE服务可能出现误码等。
终端设备执行S34时,可以工作在第一频率,也可以未工作在第一频率。如果终端设备执行S34时未工作在第一频率,则需要在工作在第一频率之后再测量第二频率,而如果终端设备执行S334时已工作在第一频率,则终端设备可以根据需求对第二频率进行测量。
S35、当第一能力大于第二能力时,网络设备向终端设备发送第二消息,终端设备接收来自网络设备的第二消息。第二消息可以指示测量第二频率,第二消息包括第一测量间隔的配置。同样的,如果终端设备要测量第二频率,也需要工作在第一频率下。
第二消息例如为物理层消息,例如第二消息可以承载在PUCCH或PUSCH上;或者,第二消息也可以是MAC CE;或者,第二消息还可以是RRC消息,等等。
其中,S35与S34是并列的步骤,即,S34和S35只会执行其中一个,不会同时执行。S35是可选的步骤,不是必须执行的,因此在图3中用虚线表示。
如果第一能力大于第二能力,那么,终端设备工作在第一频率时,如果采用无gap方 式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用一种方法,即,可以继续配置终端设备工作在第一频率时测量第二频率,但是会为终端设备配置第一gap,终端设备工作在第一频率时,可以在第一gap中测量第二频率。这样,终端设备工作在第一频率时,不会同时对第二频率进行测量以及使用第一频率与网络设备通信,在第一gap之外,终端设备可以通过第一能力在第一频率与网络设备等设备通信,不会使得终端设备对应于第一无线接入技术的通信性能有所损失,而在第一gap之内,终端设备又可以对第二频率进行测量。通过这种方式,既可以满足终端设备的测量需求,又不会使得终端设备对应于第一无线接入技术的能力受损。
为了更便于理解,可参考图4,为包括S33~S35,以及S33之前以及其他一些步骤的流程图。在图4中,如果网络设备确定第一频率组合不是终端设备所支持的频率组合,则以网络设备为终端设备配置第三gap以测量第二频率为例。
S36、当第一能力大于第二能力时,网络设备配置该终端设备工作在第一频率的通信参数为第一通信参数,以按照第三能力调度该终端设备在第一频率的通信,第三能力小于或等于第二能力。
如果第一能力大于第二能力,那么,如果终端设备工作在第一频率时,采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用不同于S35的另一种方法,例如,网络设备为该终端设备配置工作在第一频率的通信参数为第一通信参数,第一通信参数对应终端设备的第三能力,也就是说,如果终端设备被配置了第一通信参数,则终端设备就以第三能力工作,或者说,第一通信参数是用于配置终端设备的能力为第三能力的通信参数。因此,在配置第一通信参数后,网络设备可以按照第三能力调度该终端设备在第一频率的通信,终端设备也按照第三能力在第一频率与网络设备通信,且第三能力小于或等于第二能力。在这种情况下,是网络设备为终端设备配置的第三能力,因此第三能力是网络设备已知的。网络设备在为终端设备调度第一频率的通信时,也会按照第三能力来调度,使得网络设备的调度与终端设备的实际能力相匹配,终端设备能够正常按照第三能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
例如,第一无线接入技术为LTE技术,第二无线接入技术为NR技术,第一能力为4根天线,第二能力为2根天线。则网络设备可以为该终端设备配置工作在第一频率的通信参数为第一通信参数,终端设备满足第一通信参数的能力例如称为第三能力,使得第三能力小于或等于第二能力。例如网络设备可以配置第一通信参数为使用2根天线或使用1根天线,即满足第一通信参数的能力第三能力为2根天线或1根天线。而出于提高LTE通信质量的需求,网络设备可以在使得第三能力小于或等于第二能力的前提下,尽量将第一通信参数配置地较高,这样对应的第三能力可以更高,以提高通信质量,例如网络设备在可以配置第一通信参数对应的第三能力为2根天线或1根天线的情况下,可以配置第一通信参数对应的第三能力为2根天线。
S37、网络设备向终端设备发送第三消息,终端设备接收来自网络设备的第三消息。第三消息可以指示终端设备测量第二频率,且,第三消息不包括第一测量间隔的配置,第一测量间隔用于测量第二频率。同样的,如果终端设备要测量第二频率,也需要工作在第一频率下。
第三消息例如为物理层消息,例如第三消息可以承载在PUCCH或PUSCH上;或者,第三消息也可以是MAC CE;或者,第三消息还可以是RRC消息,等等。
可选的,第三消息还可以包括第一通信参数,或者第三消息可以指示第三能力。从而终端设备在接收第三消息后也能够获知被配置了工作在第一频率的能力为第三能力,则终端设备可以按照第三能力在第一频率进行通信。图3以第三消息包括第一通信参数为例。
其中,S34、S35与S36~S37,这三者是并列的步骤,即,S34、S35和S36~S37只会执行其中一个,不会同时执行。S36~S37是可选的步骤,不是必须执行的,因此在图3中用虚线表示。或者,S34与S37也可以看作是同一个步骤,第三消息和第一消息可以是同一条消息。
也就是说,如果第三能力小于或等于第二能力,表明终端设备工作在第一频率组合下时,终端设备对应于第一无线接入技术的能力不会有损失,因此网络设备可以配置终端设备正常测量第二频率。在这种情况下,网络设备无需为终端设备配置gap,终端设备在无gap的情况下对第二频率进行测量即可。则终端设备工作在第一频率时,既可以对第二频率进行测量,也可以在第一频率与网络设备进行通信,有助于提高传输效率,且终端设备的能力也能得到充分利用。
例如,第一无线接入技术为LTE技术,第二无线接入技术为NR技术,第三能力为2根天线,第二能力为2根天线。那么终端设备工作在第一频率时,可以通过2根天线在第一频率与网络设备通信,也可以通过另外2根天线对第二频率进行测量。
为了更便于理解,可参考图5,为包括S33~S34、S36~S37,以及S33之前以及其他一些步骤的流程图。在图5中,如果网络设备确定第一频率组合不是终端设备所支持的频率组合,则以网络设备为终端设备配置第三gap以测量第二频率为例,且,图5以S34和S37是同一步骤为例。
S38、当第一能力大于第二能力时,网络设备确定终端设备工作在第一频率的第二通信参数,以按照第二能力调度终端设备在第一频率的通信。
如果第一能力大于第二能力,那么,如果终端设备工作在第一频率时采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用不同于S35的另一种方法,例如,网络设备配置该终端设备工作在第一频率的通信参数为第二通信参数,第二通信参数对应终端设备的第二能力,也就是说,如果终端设备被配置了第二通信参数,则终端设备就以第二能力工作,或者说,第二通信参数是用于配置终端设备的能力为第二能力的通信参数。而此时网络设备和终端设备都明确终端设备在第一频率组合下对应于第一频率的能力为第二能力,因此网络设备无需再为终端设备配置第二通信参数,只需按第二能力调度终端设备在第一频率的通信即可。
S39、网络设备向终端设备发送第四消息,终端设备接收来自网络设备的第四消息。
第四消息例如为物理层消息,例如第四消息可以承载在PUCCH或PUSCH上;或者,第四消息也可以是MAC CE;或者,第四消息还可以是RRC消息,等等。
第四消息可以指示终端设备测量第二频率,且,第四消息不包括第一测量间隔的配置,第一测量间隔用于测量第二频率。同样的,如果终端设备要测量第二频率,也需要工作在第一频率下。
网络设备按照第二能力调度终端设备在第一频率的通信,终端设备也以第二能力在第 一频率与网络设备通信。相当于可以作为事先约定,如果第一能力大于第二能力,则网络设备以第二能力调度终端设备在第一频率的通信,终端设备也以第二能力在第一频率与网络设备通信。在这种方式下,网络设备无需再为终端设备配置工作在第一频率的能力,也就是无需再为终端设备配置对应于第一频率的第二通信参数,减少了网络设备的工作,且网络设备也无需将第二通信参数发送给终端设备,有助于节省信令开销。网络设备和终端设备都能明确终端设备是以第二能力在第一频率工作,使得网络设备的调度与终端设备的实际能力相匹配,终端设备能够正常按照第二能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
其中,S34、S35、S36~S37、S38~S39,这四者是并列的步骤,即,S34、S35、S36~S37和S38~S39这四种实施方式,只会执行其中一种,不会同时执行。S38~S39是可选的步骤,不是必须执行的,因此在图3中用虚线表示。或者,S34与S39也可以看作是同一个步骤,第三消息和第四消息可以是同一条消息。
S40、当第一能力大于第二能力时,网络设备配置终端设备在第二测量间隔内工作在第一频率的第三通信参数,以在第二测量间隔内按照第四能力调度终端设备在第一频率的通信。第四能力小于或等于第一能力,第二测量间隔用于测量第二频率。
如果第一能力大于第二能力,那么,如果终端设备工作在第一频率时采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用再一种方法。例如,网络设备确定该终端设备在第二gap内工作在第一频率的通信参数为第三通信参数,第三通信参数对应终端设备的第四能力,也就是说,如果终端设备被配置了第三通信参数,则终端设备就以第四能力工作,或者说,第三通信参数是用于配置终端设备的能力为第四能力的通信参数。第四能力小于或等于第一能力。
在配置第二通信参数后,网络设备在第二gap内可以按照第四能力调度该终端设备在第一频率的通信,在第二gap内终端设备也按照第四能力在第一频率与网络设备通信,且第四能力小于或等于第一能力。在这种情况下,是网络设备为终端设备配置的第四能力,因此第四能力是网络设备已知的。网络设备在第二gap内为终端设备调度第一频率的通信时,也会按照第四能力来调度,使得网络设备的调度与终端设备的实际能力相匹配,终端设备在第二gap内能够正常按照第四能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
S41、网络设备向终端设备发送第五消息,终端设备接收来自网络设备的第五消息。第五消息可以指示测量第二频率。同样的,如果终端设备要测量第二频率,也需要工作在第一频率下。另外,第五消息还包括第二gap的配置,第二gap用于测量第二频率。
第五消息例如为物理层消息,例如第五消息可以承载在PUCCH或PUSCH上;或者,第五消息也可以是MAC CE;或者,第五消息还可以是RRC消息,等等。
终端设备在第二gap内测量第二频率时,能够以第四能力在第一频率下通信。
可选的,第五消息还可以包括第三通信参数,或者第五消息可以指示第四能力。从而终端设备在接收第五消息后也能够获知在第二gap内被配置了工作在第一频率的能力为第四能力,则终端设备在第二gap内可以按照第四能力在第一频率进行通信。
其中,S34、S35、S36~S37、S38~S39、S40~S41,这五者是并列的步骤,即,S34、S35、S36~S37、S38~S39、以及S40~S41这五种实施方式,只会执行其中一种,不会同时 执行。S40~S41是可选的步骤,不是必须执行的,因此在图3中用虚线表示。
另外,在第二gap外,网络设备可以继续按照第一能力为该终端设备调度第一频率的通信,对于该终端设备来说,工作在第一频率时,在第二gap外,该终端设备对应于第一频率的能力还是第一能力。这样,在不对第二频率进行测量时,终端设备还是可以按照第一能力在第一频率与网络设备通信,可以提高对于终端设备的能力的利用率,也能提高通信质量。
如果按照现有的方案,网络设备会为终端设备配置第三gap,终端设备在第一频率通过第三gap测量第二频率。则在第三gap内,终端设备不能在第一频率与网络设备通信。但在本申请实施例中,网络设备为终端设备配置第二gap,在第二gap内,终端设备除了可以测量第二频率外,依然可以以第四能力在第一频率与网络设备通信。在第二gap外,终端设备可以以第一能力在第一频率与网络设备通信。这样,例如,终端设备共支持4根天线,终端设备的第一能力为4根天线,第四能力为2根天线。如果按照现有的方案,网络设备为终端设备配置第三gap,在第三gap内,终端设备只能测量第二频率,不能在第一频率与网络设备通信,但实际上在测量第二频率时,仍有2根天线可以用于在第一频率与网络设备通信,所以造成了通信资源的浪费。而本申请实施例中,网络设备为终端设备配置第二gap,在第二gap内,终端设备可以使用2根天线在测量第二频率的同时,可以使用剩余的2根天线继续在第一频率与网络设备通信,另外在第二gap外,终端设备可以继续使用4根天线在第一频率与网络设备通信。通过这种方式,可以在较大程度上提高对于终端设备的能力的利用率,减少终端设备的能力浪费。
S42、当第一能力大于第二能力时,网络设备确定终端设备在第二测量间隔内工作在第一频率的第四通信参数,以在第二测量间隔内按照第二能力调度终端设备在第一频率的通信。第二测量间隔用于测量第二频率。
如果第一能力大于第二能力,那么,如果终端设备工作在第一频率时采用无gap方式对第二频率进行测量,就会导致终端设备对应于第一无线接入技术的能力有所损失。在这种情况下,本申请实施例可以采用又一种方法。例如,网络设备确定该终端设备在第二gap内工作在第一频率的通信参数为第四通信参数,第四通信参数对应终端设备的第二能力,也就是说,如果终端设备被配置了第四通信参数,则终端设备就以第二能力工作,或者说,第四通信参数是用于配置终端设备的能力为第二能力的通信参数。而此时网络设备和终端设备都明确终端设备在第一频率组合下对应于第一频率的能力为第二能力,因此网络设备无需再为终端设备配置第四通信参数,只需按第二能力调度终端设备在第一频率的通信即可。
第四通信参数用于将终端设备的能力配置为第二能力,前文所述的第二通信参数也用于将终端设备的能力配置为第二能力,因此,所述的第四通信参数和所述的第二通信参数可以是相同的通信参数,或者也可以是不同的通信参数。
S43、网络设备向终端设备发送第六消息,终端设备接收来自网络设备的第六消息。第六消息可以指示测量第二频率。同样的,如果终端设备要测量第二频率,也需要工作在第一频率下。另外,第六消息还包括第二gap的配置,第二gap用于测量第二频率。
第六消息例如为物理层消息,例如第六消息可以承载在PUCCH或PUSCH上;或者,第六消息也可以是MAC CE;或者,第六消息还可以是RRC消息,等等。
终端设备在第二gap内测量第二频率时,能够以第二能力在第一频率下通信。
在这种方式下,网络设备无需再为终端设备配置工作在第一频率的能力,也就是无需再为终端设备配置对应于第一频率的第四通信参数,减少了网络设备的工作,且网络设备也无需将第四通信参数发送给终端设备,有助于节省信令开销。网络设备和终端设备都能明确在第二gap内终端设备是以第二能力在第一频率工作,使得网络设备的调度与终端设备的实际能力相匹配,终端设备能够正常按照第二能力在第一频率与网络设备通信,减小误码的概率,提高传输成功率。
其中,S34、S35、S36~S37、S38~S39、S40~S41、S42~S43,这六者是并列的步骤,即,S34、S35、S36~S37、S38~S39、S40~S41以及S42~S43这六种实施方式,只会执行其中一种,不会同时执行。S42~S43是可选的步骤,不是必须执行的,因此在图3中用虚线表示。
另外,在第二gap外,网络设备可以继续按照第一能力为该终端设备调度第一频率的通信,对于该终端设备来说,在第二gap外,该终端设备对应于第一频率的能力还是第一能力。这样,在不对第二频率进行测量时,终端设备还是可以按照第一能力在第一频率与网络设备通信,可以提高对于终端设备的能力的利用率,也能提高通信质量。
为了更便于理解,可参考图6,为包括S33~S34、S38,以及S33之前以及其他一些步骤的流程图。在图6中,如果网络设备确定第一频率组合不是终端设备所支持的频率组合,则以网络设备为终端设备配置第三gap以测量第二频率为例。另外,以在第二gap内网络设备按照第四能力为该终端设备调度第一频率的通信为例。
上面介绍的都是该终端设备未被配置载波聚合(carrier aggregation,CA)的情况。如果终端设备未被配置CA,则该终端设备的服务小区只有一个,例如只有第一频率,则终端设备只需确定第一频率和第二频率构成的频率组合是否是终端设备所支持的频率组合即可,且本申请实施例以第一频率组合是终端设备所支持的频率组合为例,则执行S33~S34,或者,执行S33和S35,或者,执行S33及S36~S37,或者,执行S33及S38~S39,或者,执行S33及S40~S41,或者,执行S33及S42~S43,即可。而如果该终端设备被配置了CA,则该终端设备的服务小区就可能有多个,例如该终端设备的服务小区包括主小区和辅小区,主小区可能有一个,辅小区可能有一个或多个。在这种情况下,如果对于终端设备来说,处于激活状态的服务小区的个数大于或等于2,则网络设备最初确定的就不只是第一频率和第二频率,而是还包括一个或多个频率,这一个或多个频率均对应于第一无线接入技术。例如,如果该终端设备的辅小区有一个,且对于该终端设备来说处于激活状态,则网络设备可以确定第一频率、第二频率和第三频率,第三频率为该终端设备的辅小区对应的频率,第三频率对应于第一无线接入技术;或者,该终端设备的辅小区有两个,且对于该终端设备来说均处于激活状态,则网络设备可以确定第一频率、第二频率、第三频率和第四频率,第三频率为该终端设备的一个辅小区对应的频率,第四频率为该终端设备的另一个辅小区对应的频率,第三频率和第四频率均对应于第一无线接入技术,以此类推。当然,如果终端设备虽然被配置了CA,但终端设备的辅小区对于该终端设备均未激活,则网络设备确定的也就是第一频率组合,不存在其他频率,执行S33~S34,或者,执行S33和S35,或者,执行S33及S36~S37,或者,执行S33及S38~S39,或者,执行S33及S40~S41,或者,执行S33及S42~S43,即可,这里主要讨论终端设备的辅小区处于激活状态的情况。以该终端设备的辅小区有一个,且对于该终端设备来说处于激活状态,且辅小区的频率是第三频率为例。则,网络设备如果确定第一频率和第三频率对终端设备处于激活状态,则 可以确定第一频率、第二频率和第三频率构成的频率组合是否是该终端设备支持的频率组合;如果该终端设备支持的频率组合中不包括第一频率、第二频率和第三频率构成的频率组合,则网络设备可以去激活第三频率,得到包括第一频率和第二频率的第一频率组合。当然,网络设备可以继续确定第一频率组合是否是该终端设备支持的频率组合,本申请实施例以第一频率组合是该终端设备支持的频率组合为例。
如果终端设备的辅小区处于激活状态,也可以将网络设备所确定的频率认为是一个频率组合,例如称为第二频率组合。为了便于描述,后文以第二频率组合进行介绍。第二频率组合例如包括如前所述的第一频率、第二频率和第三频率,或者包括如前所述的第一频率、第二频率、第三频率和第四频率等。但需要注意的是,第二频率组合可以是实际存在的频率组合,即,网络设备就是确定了一个频率组合;或者,第二频率组合也可以并不存在,网络设备只是确定了各个频率,这些频率并未构成一个频率组合。如果第二频率组合并不存在,则后文中所述的第二频率组合,可以理解为是网络设备所确定的各个频率。
网络设备可以先确定第二频率组合是否是终端设备所支持的频率组合,如果是,则网络设备可以继续执行S33;而如果第二频率组合不是终端设备所支持的频率组合,则可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等;或者,网络设备也可以从第二频率组合中去激活终端设备的辅小区对应的频率,之后再判断第二频率组合包括的剩余的频率的组合是否是终端设备所支持的频率组合,以此类推,下面对这种方法进行举例介绍。
以第二频率组合包括第一频率、第二频率和第三频率为例。那么,网络设备可以先确定第二频率组合是否是终端设备所支持的频率组合,如果第二频率组合是终端设备所支持的频率组合,则网络设备可以执行S33,在执行S33后,如果第一能力大于第二能力,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,则第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。例如网络设备可以确定,如果去激活第三频率,则得到的第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率,并再执行S33。或者,如果第二频率组合不是终端设备所支持的频率组合,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,则第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。例如网络设备可以确定,如果去激活第三频率,则得到的第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率,并执行S33,在执行S33后,如果第一能力小于或等于第二能力,则网络设备无需为终端设备工作在第一频率时对第二频率的测量配置gap,而如果第一能力大于第二能力,网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等;而如果第一频率组合不是终端设备所支持的频率组合,则网络设备可以不必去激活第三频率,也可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进 行测量,等等。当然本申请实施例以第一频率组合是终端设备所支持的频率组合为例。例如可参考图7,为该示例的流程图,图7以执行S35为例。
或者,以第二频率组合包括第一频率、第二频率和第三频率为例。那么,网络设备可以先确定第二频率组合是否是终端设备所支持的频率组合,如果第二频率组合是终端设备所支持的频率组合,则网络设备可以执行S33,在执行S33后,如果第一能力大于第二能力,则网络设备可以为终端设备配置仅支持第一无线接入技术时工作在第一频率的通信参数,该通信参数所对应的终端设备的能力为第三能力,并再执行S33。或者,如果第二频率组合不是终端设备所支持的频率组合,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,则第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。例如网络设备可以确定,如果去激活第三频率,则得到的第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率,并执行S33,在执行S33后,如果第一能力小于或等于第二能力,则网络设备无需为终端设备工作在第一频率时对第二频率的测量配置gap,而如果第一能力大于第二能力,网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置仅支持第一无线接入技术时工作在第一频率的通信参数,该通信参数所对应的终端设备的能力为第三能力,等等;而如果第一频率组合不是终端设备所支持的频率组合,则网络设备可以不必去激活第三频率,也可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等。当然本申请实施例以第一频率组合是终端设备所支持的频率组合为例。可参考图8,为该示例的流程图,图8以执行S36~S37为例。
或者,以第二频率组合包括第一频率、第二频率和第三频率为例。那么,网络设备可以先确定第二频率组合是否是终端设备所支持的频率组合,如果第二频率组合是终端设备所支持的频率组合,则网络设备可以执行S33,在执行S33后,如果第一能力大于第二能力,则网络设备可以为终端设备配置第二gap以测量第二频率,并再执行S33。或者,如果第二频率组合不是终端设备所支持的频率组合,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,则第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。例如网络设备可以确定,如果去激活第三频率,则得到的第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率,并执行S33,在执行S33后,如果第一能力小于或等于第二能力,则网络设备无需为终端设备工作在第一频率时对第二频率的测量配置gap,而如果第一能力大于第二能力,网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置第二gap以测量第二频率,等等;而如果第一频率组合不是终端设备所支持的频率组合,则网络设备可以不必去激活第三频率,也可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等。当然本申请实施例以第一频率组合是终端设备所支持的频率组合为例。可参考图9,为该示例的流程图,图9以执行S40或S42为例。
再以第二频率组合包括第一频率、第二频率、第三频率和第四频率为例。那么,网络设备可以先确定第二频率组合是否是终端设备所支持的频率组合,如果第二频率组合是终端设备所支持的频率组合,则网络设备可以执行S33,在执行S33后,如果第一能力大于第二能力,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,则第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。例如网络设备可以确定,如果去激活第三频率和第四频率,则得到的频率的组合是否是终端设备所支持的频率组合,如果得到的频率的组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率和第四频率,并再执行S33。或者,如果第二频率组合不是终端设备所支持的频率组合,则网络设备可以确定,如果从第二频率组合中去激活终端设备的辅小区对应的频率,第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。此时终端设备的辅小区对应的频率有两个(第三频率和第四频率),网络设备可以一并确定去激活这两个频率后第二频率组合剩余的频率的组合是否是终端设备所支持的频率组合。如果网络设备去激活第三频率和第四频率,得到第一频率组合,网络设备继续确定第一频率组合是否是终端设备所支持的频率组合。如果第一频率组合是终端设备所支持的频率组合,则网络设备可以去激活第三频率和第四频率,并执行S33,在执行S33后,如果第一能力小于或等于第二能力,则网络设备无需为终端设备工作在第一频率时对第二频率的测量配置gap,而如果第一能力大于第二能力,网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等;而如果第一频率组合不是终端设备所支持的频率组合,则网络设备可以不必去激活第三频率和第四频率,也可以不必执行S33及后续的流程,例如网络设备可以重新为终端设备配置待测量的频率,或者网络设备可以不配置终端设备进行测量,或者网络设备可以为终端设备配置gap,例如称为第三gap,终端设备工作在第一频率时可以在第三gap内对第二频率进行测量,等等。当然本申请实施例以第一频率组合是终端设备所支持的频率组合为例。
或者,如果网络设备要从第二频率组合中去激活终端设备的辅小区对应的频率,也可以先去激活终端设备的辅小区对应的一个频率,即,对终端设备的辅小区对应的频率进行单独去激活,对此不再多赘述。
在本申请实施例中,如果终端设备对应于第一无线接入技术有多个频率,且这些频率和第二频率所构成的频率组合不是终端设备所支持的频率组合,则网络设备可以考虑去激活终端设备的辅小区对应的频率,以尽量得到终端设备所支持的频率组合,从而尽量不为终端设备测量第二频率配置gap,以提高传输效率。
