本申请实施例涉及无线通信领域,并且更具体地,涉及一种通信方法和装置。
在诸如增补上行(supplementary UL,SUL)的场景中,终端设备需要在多个频带(例如,700MHz~800MHz、700MHz~900MHz、1.8GHz~2.1GHz、3.5GHz~4.9GHz,等等)之间进行切换,从而保证数据传输的性能。
通常情况下,考虑到终端设备的成本、硬件复杂度等因素,终端设备的锁相环的数目不会和频带的数目完全匹配。因此,当终端设备需要在多个频带之间进行切换,且终端设备的锁相环与频带的个数不匹配时,终端设备如何在多个频带之间完成有效切换,保证数据传输的性能,成为亟待解决的问题。

本申请实施例中所涉及到网络设备(例如,无线接入网设备)可以是终端设备通过无线方式接入到该移动通信系统中的接入设备。该无线接入网设备可以是:基站、演进型基站(evolved node B,eNB)、家庭基站、无线保真(wireless fidelity,WiFi)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)、宏基站或微基站、高频基站等。该无线接入网设备还可以为NR系统中的下一代基站(next generation node B,gNB),或者,还可以是构成基站的组件或一部分设备,如汇聚单元(central unit,CU)、分布式单元(distributed unit,DU)或基带单元(baseband unit,BBU)等。应理解,本申请的实施例中,对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中,无线接入网设备简称网络设备,如果无特殊说明,在本申请中,网络设备均指无线接入网设备。在本申请中,网络设备可以是指网络设备本身,也可以是应用于网络设备中完成无线通信处理功能的芯片。
应理解,图1示出的场景仅仅是本申请技术方案使用的一种场景示例,本申请并不排除在其它场景中也需要终端设备在多个频带之间进行切换,也就是说,本申请的技术方案可以应用于各种终端设备需要在多个频带之间进行切换的场景。
5G新空口(new radio,NR)系统中,网络设备(例如,基站)发射功率很大可以将无线电波传送到很远的距离。但是,终端设备发射功率很小,上行覆盖受限,因此上行传输的信号在到达网络设备时的接收信号强度可能不足以保证其覆盖性能。此外,还会出现上行频谱不够的问题,因此不可能依赖对数据的重传来保证其上行覆盖性能。
图1是本申请技术方案适用的一种场景示意图,如图1所示,目前NR引入增补上行(supplementary uplink,SUL)作为NR系统中上行覆盖不足时的备选。由于长期演进(long term evolution,LTE)的低频带通常具有更好的覆盖性能,SUL考虑的是从LTE所在较低频带(例如,700MHz、1.8GHz或2.1GHz)中使用载波用于NR上行链路的传输。目前已经确定终端设备在使用LTE频带进行NR传输时可与LTE上行链路时分双工(time division duplex,TDD)复用该频带。也就是说,当终端设备处于TDD中频带(2.6GHz、3.5GHz或4.9GHz)覆盖范围时,终端设备使用TDD中频带;当终端设备移动到TDD中频带(2.6GHz、3.5GHz或4.9GHz)覆盖范围之外时,终端设备在上行链路中可以采用LTE的低频带,这就增补了TDD中频带的上行覆盖短板,延伸了上行覆盖范围。当然,随着未来演进,终端设备在上行链路中也可以采用别的频带用作增补上行,进一步延伸上行覆盖范围。
也可以理解为,当终端设备在NR频带(band)(例如,2.6GHz)上传输上行数据时,可以从LTE所在较低频带(例如,700MHz/800MHz/900MHz、1.8GHz或2.1GHz)中使用载波用于NR上行传输,该载波可以理解为SUL频带。也就是说,在SUL的场景中,期望终端设备根据信道状态或者根据对应频带的负载状况,可以在700M/800M/900M、1.8G、2.1G、3.5G或4.9GHz等的多个频带之间进行动态切换。
为了便于理解本申请的技术方案,下面对本申请涉及到的几个专业术语进行简单的说明。
锁相环(phase locked loop,PLL)的切换时延:通常来说,锁相环重新锁定在一个频带上需要约300微秒。具体来说,一个频带的锁相环关了,重新锁到其他的频带上,或者
开启一个新的锁相环,都需要这样的切换时延。
发射通道(transmitter,TX):可以称为“射频(radio frequency,RF)发射通道”,也可以简称为“发射通道”。在本申请中,发射通道可以是按照如下方式工作的,但不仅限于如下方式:发射通道可接收来自基带芯片的基带信号,对基带信号进行射频处理(如上变频、放大和滤波)以得到射频信号,并最终通过天线将该射频信号辐射到空间中。例如,发射通道可以包括天线开关、天线调谐器、低噪声放大器(low noise amplifier,LNA)、功率放大器(power amplifier,PA)、混频器(mixer)、本地振荡器(local oscillator,LO)和滤波器(filter)等电子器件,这些电子器件可以根据需要集成到一个或多个芯片中。天线有时也可以认为是发射通道的一部分。
本申请的下述实施例中提及的“通道”也可以理解为“射频链”。本申请中射频链也可以替换为TX、天线、射频、发射通道、发送端口、接收通道或者它们的任意组合,以下不再赘述。
应理解,本申请实施例中提到的“频带”(band)也可以理解为,“频段”、“频点”“频谱”。也可以将本申请中的频带”理解为分量载波(component carrier,CC)(也可以简称为“载波”),即本申请的技术方案对“载波”也是完全适用的。本申请的下述实施例中主要是以“频带”为例进行描述的。
本申请中,发送射频链也可以理解为“发送”、“能发送”、“传输”或者“能传输”。相应的,发送射频链的数量可以理解为“发送的数量”、“能发送的数量”、“传输的数量”或者“能传输的数量”。发送射频链的数量还可以理解为“层数”、“天线层数”或“通道数”。
本申请实施例中提到的“切换”(switch)也可以理解为“转换”;本申请实施例提到的“切换时延”,也可以理解为“载波切换时延”、“载波转换时延”、“载波转换周期(period或interval)”或“转换间隔(gap)”;本申请实施例提到的“切换时延”,还可以称之为“载波切换准备时间中的切换时间(switching time)”或者“切换准备提前量中的切换时间(switching time)”。对应的,网络设备在进行上行调度时,会根据切换时延,进行相应的调度处理,具体可以理解为设置N2(N2可以理解为,上行处理时延或上行准备时延),以下不再赘述。
目前,终端设备有两个锁相环,并且可以在两个频带上进行动态切换。但是考虑到终端设备的成本、硬件复杂度等因素,终端设备的锁相环不会配置太多。也可以理解为,终端设备锁相环的数量基本是固定的,但是终端设备可能需要在多个频带之间进行切换。即,当终端设备需要在多个频带之间进行切换,锁相环的切换时延会更长,从而限制了终端设备在多个频带之间进行切换的灵活性,也影响了数据传输的性能。因此,当终端设备的锁相环与频带的个数不匹配时,终端设备如何在多个频带之间灵活、有效的完成切换,保证数据传输的性能,成为需要解决的技术问题。
有鉴于此,本申请提供了一种通信方法和装置,终端设备可以上报N个频带组的第一切换时延,该第一切换时延为终端设备在频带组包括的至少两个不同频带之间的切换时延。换句话说,通过终端设备上报频带组内的切换时延,使得终端设备可以在频带组内有效的进行频带切换。即,可以实现终端设备在多个频带之间灵活、有效的完成切换,保证数据传输的性能。
图2是本申请提供的一种通信方法200的示意性流程图。下面对图2所示的各步骤进行说明。需要说明的是,图2中用虚线表示的步骤是可选的,在后文中不多赘述。
步骤201,终端设备确定N(N为正整数)个频带组的第一切换时延。
其中,N个频带组包括第i个频带组,N个频带组的第一切换时延包括第i个第一切换时延。本申请中,第i个第一切换时延为终端设备在第i个频带组包括的至少两个不同频带之间的切换时延。
本申请中,提到的“频带组”可以理解为“频带集合”。其中,“频带”可以替换为“载波”、“频段”或者“频段上的载波”。“频带组”也可以替换为“载波组”或“载波集合”。“在某频带上”可以理解为“在某频带的载波上”。
本申请中,频带组#1(例如,第一频带组)与频带组#2(例如,第二频带组)中所包含的频带可以为完全不同的频带。频带组#1和频带组#2中包含的频带也可以是存在交集的。换句话说,本申请中,频带组#1和频带组#2中的频带不完全相同。即,可以有相同的频带,也可以有不同的频带。
本申请中,频带组可以包括至少一个频带。
应理解,本申请中,N个频带组中的每个频带组可以是网络设备预配置的。示例性的,网络设备可以预先配置频带组#1中包括{频带#A、频带#B},频带组#2可以包括{频带#A、频带#C}、频带组#3可以包括{频带#A、频带#B、频带#C},等等。
例如,示例性的,频带#A可以是3.5GHz、频带#B可以是2.1GHz、频带#C可以是1.8GHz、频带#D可以是700MHz/800MHz/900MHz,等等。
当本申请中的“频带”理解为“载波”时,例如,频带#A支持三个载波,分别为载波#1、载波#2、载波#3;频带#B支持四个载波,分别为载波#4、载波#5、载波#6、载波#7;频带#C支持两个载波,分别为载波#8、载波#9;频带#D支持两个载波,分别为载波#10、载波#11。其中,“频带组#1中包括{频带#A频带#B}”也可以理解为,载波组#1中包括载波#1,载波#6;频带组#2可以包括{频带#A、频带#C},也可以理解为,载波组#2中包括载波#8,载波#3。
本申请中,下述频带组内的切换,例如,也可以理解为,载波组#1中载波#1和载波#6之间的切换。又例如,载波组#2中载波#3和载波#8之间的切换。下述频带组之间的切换(例如,频带组#1与频带组#2之间的切换)也可以理解为,载波组之间的切换(例如,载波组#1与载波组#2之间的切换)。
在一种可能的实现方式中,网络设备可以半静态配置的频带组。示例性的,网络设备可以每隔五个时隙为终端设备配置一次频带组。例如,终端设备可以在该五个时隙内将锁相环预锁定在相应的频带上。
在一种可能的实现方式中,本申请中,N个频带组中的每个频带组都可以对应一个第一切换时延。在另一种可能的实现方式中,N个频带组中的某些频带组可以对应相同的第一切换时延。也可以理解为,终端设备在确定N个频带组对应的第一切换时延时,可以为每个频带组分别选择第一切换时延,也可以为某几个频带组共同选择一个相同的切换时延。即,本申请中对终端设备的内部具体实现不做限定。
步骤201中,“终端设备确定N个频带组的第一切换时延”,例如,可以理解为,终端设备上可以预配置(或者,也可以是,“协议预定义”)第一切换集合,该第一切换集
合中包括不同的第一切换时延,终端设备可以为N个频带组在第一切换集合中选择对应的第一切换时延。示例性的,第一切换集合中的数值可以小于或者等于35微秒。例如,第一切换集合可以包括{0微秒,30微秒,35微秒},或者,第一切换集合可以包括{0微秒、35微秒},又或者,第一切换集合可以包括{0微秒,15微秒,20微秒,35微秒}。
本申请中,假设终端设备的锁相环为两个,终端设备在频带组中的频带#A和频带#B之间进行切换时,考虑到下述场景:假设锁相环#1锁定频带#A,如果锁相环#2可以预先锁定在频带#B上,并且频带#A在通道#1上,频带#B在通道#2上(也可以理解为,频带#A和频带#B异通道),此时由于锁相环也预先锁定在频带#B上,终端设备在频带组中的频带#A和频带#B之间便可以进行无缝切换,即,切换时延为0微秒。换句话说,本申请中,基于上述场景,还提出了在频带组内两个不同频带之间进行切换为0微秒,可以极大降低终端设备在两个频带之间进行切换的时延,更加有效的完成切换,保证数据传输的性能。如果假设,频带#A和频带#B都可以在通道#1上,此时由于锁相环也预先锁定在频带#B上,终端设备在频带组中的频带#A和频带#B进行切换时切换,仅仅需要通道中频带的切换时延(例如,之前通道#1上为频带#A,需要将通道#1的频带切换至频带#B,仅需要通道中频带(“频点”))的转换(即,通道转换时延),即,35微秒。
本申请中,步骤201为可选的步骤,即终端设备可以不执行步骤201,此时,也可以理解为,终端设备的内部实现中不需要“确定”的动作,直接执行步骤202。
步骤202,终端设备向网络设备发送第一信息,第一信息包括N个频带组的第一切换时延。
对应的,网络设备可以接收第一信息,并且基于第一信息确定上行数据的调度。
例如,终端设备可以向网络设备上报第一能力信息(第一信息的一个示例),该能力信息中包括N个频带组对应的第一切换时延。
作为一个示例,终端设备上报第一能力信息,第一能力信息包括第一切换时延为0秒。此时,第一切换时延0微秒例如可以理解为,终端设备在N个频带组内的不同频带之间进行切换时的切换时延都可以是0微秒,或者,也可以理解为,终端设备在N个频带组中的前X1个频带组包括的不同频带之间进行切换的时延均为0微秒,又或者,可以理解为,终端设备在N个频带组中的后Y1个频带组包括的不同频带之间进行切换的时延均为0微秒。其中,X1、Y1的值可以是协议预定义的或者网络设备预配置的,不做限定。
作为另一个示例,终端设备上报第一能力信息,第一能力信息包括第一切换时延为0秒、35微秒。例如,可以理解为,终端设备在N个频带组中的前X2个频带组的不同频带之间进行切换的时延均为0微秒,又或者,可以理解为,终端设备在N个频带组中的后Y2个频带组的不同频带之间进行切换的时延为35微秒,等等。其中,X2、Y2的值可以是协议预定义的或者是网络设备预配置的,不做限定。
在一种实现方式中,第一信息还可以包括终端设备在至少两个不同频带上支持的发送射频链的数量,该第一能力信息用于网络设备确定上行数据的调度。
作为一个示例,终端设备发送的第一信息可以包括频带组#1{频带#A、频带#B}中频带#A支持的射频链的数据以及频带#B支持的射频链的数量。例如,频带#A上支持两个射频链,频带#B上支持两个射频链。又例如,频带#A上支持两个射频链,频带#B上支持1个射频链。再例如,频带#A上支持1个射频链,频带#B上支持1个射频链,等等。
网络设备可以基于终端设备上报的频带组的第一切换时延和/或频带组内各个频带支持的射频链的数量确定为终端设备调度数据。
在步骤202之前还可以包括步骤203,终端设备接收来自网络设备的频带组标识信息,该频带组标识信息包括N个频带组标识。
在一种可能的实现方式中,本申请中,频带组标识也可以是预配置或者协议预定义的。
对应的,网络设备向终端设备发送频带组标识信息。例如,网络设备可以通过无线资源控制(radio resource control,RRC)信令、媒体接入控制(media access control,MAC)信令等向终端设备发送频带组标识信息。
其中,步骤201和步骤203之间可以没有先后顺序。例如,终端设备可以在确定N个频带组的第一切换时延后,再接收来自网络设备的频带组标识信息。又例如,终端设备也可以先接收来自网络设备的频带组标识信息,再确定N频带组的第一切换时延,再例如,终端设备可以在确定N个频带组的第一切换时延的同时,接收来自网络设备的频带组标识信息,本申请不予限定。
例如,本申请中,网络设备可以为终端设备配置N个频带组标识,N个频带组标识可以与N个频带组一一对应。进一步的,此时,N个频带组标识可以与N个频带组的切换时延一一对应。
例如,终端设备接收来自网络设备的频带组标识信息,该频带组标识信息包括频带组标识#1(例如,group#1)、频带组标识#2(例如,group#2)、频带组标识#3(例如,group#3),等等。例如,group#1标识的频带组为{频带#A,频带#D},又例如,group#2标识的频带组为{频带#B,频带#D},再例如,group#3标识的频带组为{频带#C,频带#D}。
此时,终端设备在步骤202中发送的第一信息还可以包括第i个频带组标识,其中第i个频带组标识为N个频带组标识中的任意一个。
作为一个示例,终端设备上报第一能力信息,第一能力信息包括{频带组标识#1,第一切换时延为0微秒}、{频带组标识#2,第一切换时延为35微秒}、{频带组标识#3,第一切换时延为30微秒},等等。
步骤204,终端设备接收来自网络设备的第二信息,该第二信息指示目标频带组标识。
对应的,网络设备向终端设备发送第二信息。例如,网络设备可以通过下行控制信息(downlink control information,DCI)指示目标频带组标识。
本申请中,目标频带组标识可以是N个频带组标识中的一个或者多个频带组标识。例如,网络设备为终端设备配置了N个频带组标识,目标频带组标识可以是其中的频带组标识#2、频带组标识#5、频带组标识#6。
步骤205,终端设备根据第二信息,在目标频带组标识对应的目标频带组内进行频带切换。
例如,终端设备可以根据第二信息指示的目标频带组标识,在该目标频带组标识对应的目标频带组内进行频带切换。
步骤206,终端设备在该目标频带组上发送上行数据。
也可以理解为,网络设备可以基于终端设备上报的第一切换时延,为终端设备调度与第一切换时延匹配的资源,从而使得终端设备可以灵活、有效进行频带切换,从而提高数据传输的性能。
本申请中的“资源”可以理解为,时域资源、频域资源、物理资源块、资源块,等等,不做限定。
图3是本申请提供的通信方法300,方法300从终端设备与网络设备交互的角度示例了本申请技术方案的具体实施例步骤,方法300包括:
本申请中,网络设备可以预配置频带组,示例性的,网络设备可以预先配置频带组#1中包括{频带#A、频带#B},频带组#2可以包括{频带#A、频带#C}、频带组#3可以包括{频带#A、频带#B、频带#C},等等。
在一种可能的实现方式中,网络设备可以半静态配置,具体的,可以参照方法200中的描述,此处不再赘述。
步骤301,网络设备向终端设备发送频带组标识信息,该频带组标识信息包括N个频带组标识。
在一种可能的实现方式中,本申请中,频带组标识也可以是预配置或协议预定义的。
本申请中,例如,该N个频带组标识可以与N个频带组一一对应。
例如,网络设备可以向终端设备发送RRC信令,该RRC信令中包括N个频带组标识。示例性的,频带组标识#1(例如,group#1)用于标识频带组#1{频带#A、频带#B},频带组标识#2(例如,group#2)用于标识频带组#2{频带#A、频带#C}、频带组标识#3(例如,group#3)用于标识频带组#3{频带#A、频带#B、频带#C},等等。
步骤302,终端设备接收来自网络设备的频带组标识信息,并且确定N个频带组的第一切换时延。
本申请中,例如,N个频带组的第一切换时延可以与N个频带组标识一一对应。
例如,终端设备可以确定group#1对应的第一切换时延为0微秒,group#2对应的第一切换时延为35微秒,等等。具体地,终端设备可以在第一切换集合中为各个频带组选择对应的切换时延,关于“第一切换集合”中数值的说明可以参照上述方法200中的描述进行理解,此处不再赘述。
需要说明的是,本申请中,第一切换集合、第二切换集合、第三切换集合、第四切换集合中的数值集合只作为示例。例如,第一切换集合还可以为包括35微秒、140微秒的集合。又例如,第一切换集合还可以为包括0微秒,35微秒,140微秒的集合。相应的,下述实施例中的第二切换集合、第三切换集合、第四切换集合中的数值也仅仅为示例性的,各个切换集合中也可以为包含其他数值的集合。本申请中,各个切换结合之间(例如,第一切换时延集合和第二切换时延集合)可以有交集,也可以为完全不同的集合。
进一步的,终端设备在确定每个频带组对应的第一切换时延,还可以考虑每个频带支持的射频链的数量。例如,频带#A上支持两个射频链(“射频链”也可记为“TX”),频带#B上支持两个射频链、频带#C上支持传输两个射频链。又或者,频带#A上支持两个射频链,频带#B上支持1个射频链、频带#C上支持传输两个射频链。再或者,频带#A上支持1个射频链,频带#B上支持1个射频链、频带#C上支持传输两个射频链,等等。例如,表格1所示。
表格1
例如,终端设备确定group#1的第一切换时延为0微秒,表示终端设备在频带#A和频带#B之间(例如,从频带#A支持的两个射频链切换到频带#B支持的两个射频链,或者,从频带#B支持的两个射频链切换到频带#A支持的两个射频链)切换需要的切换时延为0。
又例如,终端设备确定group#3的第一切换时延为35微秒,表示终端设备在频带#A支持的两射频链、频带#B支持的一个射频链、频带#C支持的两个射频链,每两个频带之间(例如,从频带#A支持的两个射频链切换到频带#B支持的两个射频链,或者,从频带#A支持的两个射频链切换到频带#C支持的两个射频链,或者,从频带#B支持的两个射频链切换到频带#A支持的两个射频链,或者,从频带#B支持的两个射频链切换到频带#C支持的两个射频链,等等)切换需要的切换时延为35微秒。
本实施例中,通过区分频带组以及通过网络设备配置各个频带组标识,使得终端设备可以上报该频带组标识对应的第一切换时延(也可以理解为,终端设备可以按照频带组的粒度上报第一切换时延),相比目前终端设备按照每个频带的粒度上报切换时延的方式,可以极大的减小信令开销。
步骤303,终端设备向网络设备发送第一信息,第一信息包括N个频带组的第一切换时延。
在一种可能实现方式中,终端设备可以向网络设备发送第一能力信息(第一信息的一例),该第一能力信息包括N个频带组的第一切换时延。例如,第一切换时延0微秒、第一切换时延为35微秒。具体地,可以参照方法200中的步骤202中的描述进行理解,此处不再赘述。
在另一种可能的实现方式中,该第一能力信息包括频带组标识以及该频带组标识对应的第一切换时延。例如,第一能力信息包括{group#1,第一切换时延为0微秒}、{group#2,第一切换时延为35微秒},等等。
在又一种可能的实现方式中,该第一能力信息中还可以包括频带组内的频带支持发送射频链的数量。例如,group#1{频带#A、频带#B}中频带#A支持的射频链的数量以及频带#B支持的射频链的数量。例如,频带#A上支持两个射频链,频带#B上支持两个射频链。又例如,频带#A上支持两个射频链,频带#B上支持1个射频链。再例如,频带#A上支持1个射频链,频带#B上支持1个射频链。
在一种可能的实现方式中,第一能力信息还可以包括终端设备从缺省状态或者回退状态切换到新的频带所需要的切换时延。此时,考虑到终端设备通过当前频段下完成传输后,还可以回退到缺省状态/回退状态所对应的频带下。例如,该切换时延可以为35微秒。回退到缺省状态/回退状态所对应的频带,表示锁相环锁定到缺省状态/回退状态所对应的频带。本申请中,缺省状态/回退状态可以是预定义的,或者网络设备预先配置的。本申请中,预先配置可以理解为网络设备通过RRC信令配置。
在一种可能的实现方式中,终端设备也可以上报期望的K1或K2中至少一项的最小值,使得网络设备可以为终端设备确定合适的K1或K2的值(具体的,对于K1和K2的解释可以参见步骤304中的描述)。
步骤304,网络设备接收第一信息,并根据第一信息确定上行数据的调度。
例如,终端设备可以根据第一信息确定K2和/或K1,其中,K2为调度上行数据传输的时延(也可以称为:数据处理时间或数据准备时间),K1为从调度物理下行共享信道(physical downlink shared channel,PDSCH)到反馈物理上行控制信道(physical uplink control channel,PUCCH)之间的时延。具体的,有关K2的说明可以参照第三代移动通信伙伴项目(the 3rd generation partner project,3GPP)中技术规范(technical specification,TS)38.214进行理解,有关K1的说明可以参照3GPP中的技术规范TS38.213,本申请中不再具体说明。
作为一个示例,网络设备接收N个频带组对应的第一切换时延,并且根据第一信息确定上行数据的调度。例如,网络设备可以根据各个频带组对应的第一切换时延,确定调度哪个时隙和/或哪些符号的资源(也可以是,帧的资源、迷你时隙的资源等等,不做限定),作为切换后的频带的数据传输。具体的,假设网络设备接收到第一信息包括:group#2({频带#A、频带#C})对应的第一切换时延为35微秒,网络设备可以确定终端设备发送上行数据的资源。例如,通过频带#A传输数据的时隙与通过频带#B传输数据的时隙间隔一个符号。
作为另一个示例,网络设备接收N个频带组对应的第一切换时延以及N个频带组内的频带支持发送射频链的数量,并且根据第一信息确定上行数据的调度。具体的,网络设备可以根据:group#1{频带#A、频带#B}对应的切换时延为0微秒,频带#A上支持两个射频链,频带#B上支持两个射频链,为终端设备调度上行数据的资源。例如,通过频带#A传输数据的时隙与通过频带#B传输数据的时隙间隔一个符号。
步骤305,网络设备向终端设备发送第二信息,第二信息用于指示目标频带组标识。
例如,网络设备可以通过DCI指示目标频带组标识。本申请中,目标频带组标识可以是N个频带组标识中的一个或者多个频带组标识。例如,网络设备为终端设备配置了N个频带组标识,目标频带组标识可以是其中的group#1、group#5、group#6。
步骤306,终端设备接收第二信息,并根据第二信息的指示在目标频带组标识对应的目标频带组内进行频带切换。
作为一个示例,假设第二信息指示的目标频带组标识为group#1,此时,终端设备可以在group#1标识的频带组{频带#B,频带#D}内进行频带切换。例如,终端设备当前在时隙#1(slot#1)通过频段#B传输数据,假设终端设备上报在频带组标识#2标识的频带组内进行切换需要的切换时间为0微秒(如前所述,由于锁相环预置了且两个频带异通道,终端设备没有锁相环切换时延)。此时,网络设备可以为终端设备调度在时隙#2上通过频段#D传输数据,即终端设备可以在连续的两个时隙和连续的符号上进行数据传输。又例如,假设终端设备上报在频带组标识#2标识的频带组内进行切换需要的切换时间为35微秒(此时,终端设备没有锁相环切换时延,但需要通道转换时延)。此时,网络设备可以为终端设备调度从时隙#2第二个符号或者从第三个符号上开始通过频段#D传输数据。根据不同的子载波间隔,切换时间需要占用的符号数不同,因此调度的符号数可以不同。
作为另一个示例,当终端设备在网络设备调度的时隙上无法及时完成频带组内的频带切换时(网络设备可以为终端设备调度从时隙#2第一个符号开始通过频段#D传输数据),终端设备对上行数据进行打孔(puncture)。此时,网络设备可以按照原来调度的上行符号个数进行检测,也可以按照可能减少的符号数来检测。对于后者,可以在上行解调参考信号(UL DMRS)上增加掩码(mask)或加绕,通过该mask或加绕信息指示目前减少的符号个数,从而使得网络设备能根据减少的符号数来进行对应的检测。例如,网络设备调度上行传输十三个符号,当终端设备的切换时延还需要多占一个符号时,即终端设备发现一个符号用于频带组内切换的时延不够时,终端设备对更多的符号进行打孔。
可选的,终端设备上行传输可以按照十个符号去编码。可选的,网络设备可以检测前四个符号能量为0,优先按照十个符号译码,或者可以按照甚至十一个符号,十二个符号,十三符号多次译码。例如,网络设备可以直接根据十三个符号去检测,损失部分精确度,但这对于低阶调制编码策略(modulation and coding scheme,MCS)(例如,非256正交幅度调制(quadrature amplitude modulation,QAM))来说性能影响不会很大。
步骤307,终端设备在该目标频带组上发送上行数据。
例如,终端设备可以在网络设备调度的资源上通过目标频带组中的频带发送上行数据。
基于本实施例提供的方法,终端设备可以上报N个频带组的第一切换时延,该第一切换时延为终端设备在频带组包括的至少两个不同频带之间的切换时延。换句话说,通过终端设备上报频带组内的切换时延,网络设备可以确定K2时延,使得终端设备可以在频带组内有效的进行频带切换。从而实现终端设备在多个频带之间灵活、有效的完成切换,保证数据传输的性能。
本申请还提供了一种通信方法400,其中,该方法400从终端设备与网络设备交互的角度示例了本申请技术方案的另一具体实施例步骤,方法400的流程和方法300的流程类似,可以参照图3的流程进行理解,不再示出。
本实施例中,网络设备可以预配置频带组,示例性的,网络设备可以预先配置频带组#1中包括{频带#A、频带#B},频带组#2可以包括{频带#A、频带#C}、频带组#3可以包括{频带#A、频带#B、频带#C}、频带组#4可以包括{频带#D}、频带组#5可以包括{频带#A}等等。
需要说明的是,方法300中频带组中包含的频带至少为两个,与方法300相比,在方法400中频带组中包含的频带可以是至少一个。即,在方法400中可以存在频带组中的频带数量只有一个频带的情况。
步骤401,网络设备向终端设备发送频带组标识信息,该频带组标识信息至少包括第一频带组标识和第二频带组标识。
例如,网络设备可以向终端设备发送RRC信令,该RRC信令中包括X个频带组标识。示例性的,频带组标识#1(例如,group#1)用于标识频带组#1{频带#A、频带#B},频带组标识#2(例如,group#2)用于标识频带组#2{频带#A、频带#C}、频带组标识#3(例如,group#3)用于标识频带组#3{频带#A、频带#B、频带#C},频带组标识#4(例如,group#4)用于标识频带组#4{频带#D},频带组标识#5(例如,group#5)用于标识频带组#5{频带#A},等等。
步骤402,终端设备接收来自网络设备的频带组标识信息,并且确定M(M为正整数)
个第二切换时延。
在一种可能的实现方式中,本申请中,频带组标识也可以是预配置或协议预定义的。
例如,第j个第二切换时延为终端设备在第一频带组和第二频带组之间进行切换的时延,第j个第二切换时延为M个第二切换时延中的一个。又例如,第k个第二切换时延为终端设备在第三频带组和第四频带组之间进行切换的时延,第k个第二切换时延为M个第二切换时延中的另外一个,等等。本实施例中,M个第二切换时延中的每个第二切换时延表示终端设备在两个频带组之间进行切换的时延。
本实施例中,第二切换时延可以为第二切换集合中的一个。示例性的,第二切换集合中的数值可以大于35微秒,小于或者等于1毫秒。例如,第二切换集合可以包括{140微秒,210微秒,280微秒},或者,第二切换集合可以包括{140微秒、210微秒、500微秒},又或者,第二切换集合可以包括{140微秒,280微秒,400微秒,500微秒,1毫秒},等等。应理解,上述第二切换集合中的数值仅仅是示例性的,例如,第二切换集合也可以包括0微秒、35微秒,等等,不做限定。
作为一个示例,假设终端设备的锁相环为两个,终端设备在group#4和group#2之间进行切换时,考虑到下述场景:假设锁相环#1锁定频带#D,锁相环#2锁定在频带#B上。当终端设备从频带#D切换到频带#A和频带#C时,可以采用锁相环串行切换的方式。例如,可以先将锁相环#1重新锁定在频带#A上,然后将锁相环#2重新锁定在频带#D上。即,锁相环串行切换的时延为280微秒。换句话说,本申请中,基于上述场景,还提出了在频带组之间进行切换为280微秒,可以充分考虑到终端设备在两个频带组之间进行切换的时延,便于网络设备的资源调度。使得终端设备更加有效的完成切换,保证数据传输的性能。应理解,锁相环串行切换的时延,也可以是其他的数值,例如,300微秒、350微秒或者400微秒,等等,此处不予限定。
作为另一个示例,假设终端设备的锁相环为两个,终端设备在group#4和group#2之间进行切换时,考虑到下述场景:假设锁相环#1锁定频带#D,锁相环#2锁定在频带#B上。当终端设备从频带#D切换到频带#A和频带#C时,可以采用锁相环部分串行切换的方式。例如,先将锁相环#1重新锁定在频带#A上,大约在70微秒的时候,同时也将锁相环#2重新锁定在频带#D上。即,锁相环部分串行切换的时延为210微秒。应理解,锁相环部分串行切换的时延,也可以是其他的数值,例如,230微秒、245微秒、250微秒,等等,此处不予限定。
作为又一个示例,假设终端设备的锁相环为两个,终端设备在group#4和group#2之间进行切换时,考虑到下述场景:假设锁相环#1锁定频带#D,锁相环#2锁定在频带#B上。当终端设备从频带#D切换到频带#A和频带#C时,可以采用锁相环并行切换的方式。例如,可以再将锁相环#1重新锁定在频带#A的同时也将锁相环#2重新锁定在频带#D上。即,锁相环并行切换的时延为140微秒。应理解,锁相环并行切换的时延,也可以是其他的数值,例如,200微秒、150微秒或者180微秒,等等,此处不予限定。
进一步的,终端设备确定第二切换时延时,还可以考虑每个频带支持的射频链的数量。例如,频带#A上支持两个射频链,频带#B上支持两个射频链、频带#C上支持传输两个射频链。又或者,频带#A上支持两个射频链,频带#B上支持1个射频链、频带#C上支持传输两个射频链。再或者,频带#A上支持1个射频链,频带#B上支持1个射频链、
频带#C上支持传输两个射频链、频带#D上支持两个射频链,等等。例如,表格2所示。
表格2
例如,终端设备确定在group#4和group#1之间(可以是从group#4切换到group#1,也可以是从group#1切换到group#4)进行切换的第二切换时延为140微秒。例如,此时可以是锁相环的并行切换。
又例如,终端设备确定在group#4和group#5之间(可以是从group#4切换到group#5,也可以是从group#5切换到group#4)进行切换的第二切换时延为140微秒。例如,此时可以也是锁相环的并行切换。
再例如,终端设备确定在group#5和group#2之间(可以是从group#5切换到group#2,也可以是从group#2切换到group#5)进行切换的第二切换时延为210微秒。例如,此时可以也是锁相环的部分串行切换。

本实施例中,通过区分频带组以及网络设备配置各个频带组标识,使得终端设备可以上报该频带组标识对应的第二切换时延(也可以理解为,按照频带组的粒度上报第二切换时延),相比目前终端设备按照每个频带的粒度上报切换时延的方式,可以极大的减小信令开销。

切换时延。例如,第三信息包括{group#1,group#4,第二切换时延为140微秒}、{group#4,group#5,第二切换时延为140微秒}、{group#5,group#1,第二切换时延为280微秒},等等。
在又一种可能的实现方式中,该第三信息中还可以包括频带组内的频带支持发送射频链的数量。例如,group#1{频带#A、频带#B}中频带#A支持的射频链的数据以及频带#B支持的射频链的数量。例如,频带#A上支持1个射频链,频带#B上支持1个射频链。又例如,group#5{频带#A}中频带#A支持的射频链的数量为两个。
在一种可能的实现方式中,第三信息还可以包括终端设备能接受的K2’(例如,K2’大于或等于三个时隙的时间或四个时隙的时间)。例如,K2’可以是在现有K2的基础上加上锁相环锁定时间。作为一种示例,可以为K2’单独定义一张表格,其中K2’不同于现有的K2表格中所列举的值。网络设备给终端设备指示K2’时,需要表格索引指示以及K2’的值指示。作为另一种示例,可以在目前K2表格的基础上再额外增加K2’的值,例如可以扩展比特位,此时不需要表格索引指示。可选的,网络设备可以根据终端设备上报的K2’,为终端设备确定上行数据的调度。在另一种可能的实现方式中,终端设备也可以上报期望的K1、K2的最小值,使得网络设备可以为终端设备确定合适的K1、K2的值。
在一种可能的实现方式中,第三信息还可以包括终端设备从缺省状态或者回退状态切换到新的频带所需要的切换时延。此时,考虑到终端设备通过当前频段下完成传输后,还可以回退到缺省状态/回退状态所对应的频带下传输数据。例如,该切换时延可以为140微秒、210微秒、280微秒。又例如,还可以是400微秒、500微秒、1毫秒等等。

步骤406,终端设备接收第四信息,并根据第四信息的指示在目标频带组标识对应的目标频带组内进行频带切换。
作为一个示例,假设第四信息指示的目标频带组标识为group#1、group#4、group#5,此时,终端设备可以在这三个频带组之间进行频带切换。假设终端设备在group#1、group#4之间进行切换。例如,终端设备当前在时隙#1(slot#1)通过group#1所包含的频带传输数据,假设终端设备上报在group#1和group#4之间进行切换需要的切换时间为140微秒
(如前所述,可以是锁相环并行切换)。此时,网络设备可以为终端设备调度从时隙#2第五个符号或者从第六个符号上开始通过group#4传输数据。
作为另一个示例,当终端设备在网络设备调度的时隙上无法及时完成频带组之间的切换时(网络设备为终端设备调度从时隙#2第二个符号开始通过group#4传输数据),终端设备可以对上行数据进行打孔(puncture)。此时,网络设备可以按照原来调度的上行符号个数进行检测,也可以按照可能减少的符号数来检测。对于后者,可以在上行解调参考信号(UL DMRS)上增加mask,通过该mask指示目前减少的符号个数,从而使得网络设备能根据减少的符号数来进行对应的检测。例如,网络设备调度上行传输13个符号,当终端设备的切换时延还需要多占三个符号时,即终端设备发现一个符号用于频带组之间切换的时延不够时,终端设备对更多的符号进行打孔。
可选的,终端设备上行传输可以按照十个符号去编码。可选的,网络设备可以检测前四个符号能量为0,优先按照十个符号译码,或者可以按照甚至十一个符号,十二个符号,十三符号多次译码。例如,网络设备可以直接根据十三个符号去检测,损失部分精确度,但这对于MCS(例如,非256的QAM)来说性能影响不会很大。

本申请中,还提供一种方法700,网络设备和终端设备的交互流程参照方法600中的图4进行理解,不再示出。
步骤701,终端设备向网络设备上报第四切换时延。
本实施例中,该第四切换时延可以有两种值,或者该两种值中的任意一种值。第一种值例如可以是用于网络设备确定为终端设备调度数据的提前量。例如,为3gpp标准中Tproc中的切换时间(switch time)。又例如,该提前量可以包括:射频调谐的时延以及软件的时序提前量(例如,软件发送指令停止之前锁相环、网络设备构建新指令,并配置给终端设备指示开启新的锁相环,等等)。第二种值为频带组内、频带组之间或者状态转换间的中断。其中,第一种值(第一种值可以大于或者等于280微秒,例如,第一种值可以是280微秒、300微秒、430微秒、500微秒、1毫秒)用于进行调度切换准备,属于调度切换准备时间中的切换时间或射频调整时间(tuning/retuning time)。第二种值(第二种值可以小于280微秒,例如,0微秒、35微秒、140微秒、200微秒)可以用于频带组内、频带组之间或者状态转换间的gap,或用于频带组内、频带组之间或者状态转换间的中断。
步骤702,网络设备接收第四切换时延,并且可以根据第三切换时延为终端设备确定上行数据的调度。
例如,网络设备可以根据第一种值确定为终端设备确定调度上行数据的资源在哪些符号上或者哪些时隙上。
又例如,网络设备根据第二种值,确定终端设备频带组内切换、频带组之间进行切换以及状态之间进行切换需要的时延,并根据该时延确定终端设备上行数据的时域资源的位置。
可选的,还包括步骤703,网络设备向终端设备发送指示信息,指示终端设备在目标频带之间进行切换。
例如,目标频带可以是频带#A和频带#B。又例如,目标状态可以是频带#A和频带#C,等等。
可选的,还包括步骤704,终端设备接收指示信息,并在目标频带之间进行频带切换。
例如,终端设备可以在频带#A和频带#B之间进行切换,或者终端设备在频带#A和频带#C之间进行切换,等等。
步骤705,终端设备在网络设备调度的资源上通过目标频带发送上行数据。
作为一个示例,对于上述第二种值,当终端设备在网络设备调度的时隙上无法及时完成频带切换时,终端设备对上行数据进行打孔(puncture)。此时,网络设备可以按照原来调度的上行符号个数进行检测,也可以按照可能减少的符号数来检测。对于后者,可以在上行解调参考信号(UL DMRS)上增加掩码(mask)或加绕,通过该mask或加绕信息指示目前减少的符号个数,从而使得网络设备能根据减少的符号数来进行对应的检测。例如,
网络设备调度上行传输十三个符号,当终端设备的切换时延还需要多占一个符号时,即终端设备发现一个符号用于频带组内切换的时延不够时,终端设备对更多的符号进行打孔。
可选的,终端设备上行传输可以按照十个符号去编码。可选的,网络设备可以检测前四个符号能量为0,优先按照十个符号译码,或者可以按照甚至十一个符号,十二个符号,十三符号多次译码。例如,网络设备可以直接根据十三个符号去检测,损失部分精确度,但这对于MCS(例如,非256的QAM)来说性能影响不会很大。
基于上述技术方案,本申请中,终端设备可以上报第四切换时延,该第四切换时延可以包括两种值。终端设备可以基于该两种值对相应的符号进行编码,如果终端设备在网络设备调度的时隙上无法完成数据传输时,还可以打孔,并指示网络设备,在保证终端设备完成频带切换的同时,还可以减少网络设备译码的时长,保证数据传输的性能。
进一步的,本申请中,考虑到四个频带下终端设备频带以及各个频带支持的发送射频链的数量之间的组合会增多(例如,会有十种组合),考虑下述两个原因:(1)片上存储量有限。片上存储只支持最多六种组合状态对应的射频通道参数。四个频带(四个载波)分别支持传输两个射频链,组合的数目可以达到十种。这导致片外与片内的动态倒换,由此产生射频参数倒换时间。因此,需要减少四个频带下所支持的并发组合的状态数量。(2)某些1TX+1TX组合(例如,频带#A支持一个发送射频链、频带#B支持一个发送射频链)可能有内部调制(inter-modulate,IMD)干扰问题,使得产品设计难度增加。终端设备可以上报在这十种状态组合中所支持的状态组合,例如,终端可以将各个频带具体支持的2TX、1TX、1TX+1TX并发组合可以通过用户能力上报给网络设备。本申请中,提出终端设备上报的组合的状态数量不超过六种,从而保证能在片上进行存储,减少该动态倒换所需要的时间。
本申请中,在一种可能的实现方式中无论子载波间隔(sub-carrier space,SCS)为多少,均可以规定频带组内之间的切换时延、频带组之间的切换时延,或者状态之间的切换时延大于1毫秒。
本申请中,方法200、方法300、方法400以及方法500之间也可以结合。例如,终端设备可以同时向网络设备上报频带组内的切换时延以及频带组间的切换时延。又例如,网络设备可以同时为终端设备发送频带组标识、频带组切换标识等等。即,上述频带组内切换的技术方案和频带组之间的切换的技术方案可以互相结合。
可以理解,本申请实施例中的方法200~方法700中的例子仅仅是为了便于本领域技术人员理解本申请实施例,并非要将本申请实施例限于例示的具体场景。本领域技术人员根据方法200~方法700中的例子,显然可以进行各种等价的修改或变化,这样的修改或变化也落入本申请实施例的范围内。
还可以理解,本申请的各实施例中的一些可选的特征,在某些场景下,可以不依赖于其他特征,也可以在某些场景下,与其他特征进行结合,不作限定。
还可以理解,本申请中描述的各个实施例可以为独立的方案,也可以根据内在逻辑进行组合,这些方案都落入本申请的保护范围中。并且实施例中出现的各个术语的解释或说明可以在各个实施例中互相参考或解释,对此不作限定。
还可以理解,在本申请的各实施例中的各种数字序号的大小并不意味着执行顺序的先后,仅为描述方便进行的区分,不应对本申请实施例的实施过程构成任何限定。例如,方
法300中,步骤301可以与步骤305可以同时进行,即网络设备在向终端设备发送频带组标识的时候也同时下发目标频带组标识。
应该理解,本申请中的预定义可以理解为定义、预先定义、存储、预存储、预协商、预配置、固化、或预烧制。
可以理解,在本申请中,“在…情况下”、“若”以及“如果”均指在某种客观情况下装置会做出相应的处理,并非是限定时间,且也不要求装置实现时一定要有判断的动作,也不意味着存在其它限定。
可以理解,本文中术语“和/或”,仅仅是一种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这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
