Description

一种载波确定方法、载波确定装置及存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种载波确定方法、载波确定装置及存储介质。
背景技术
目前，针对载波除包含有上行载波和下行载波对应的载波对之外，还包括有辅助上行载波(Supplementary uplink，SUL)。SUL一般都部署在低频，SUL的带宽要比一般的上行载波小，其主要目的是扩展上行覆盖。由于低频载波路损较小，终端可以使用处在低频的SUL来获得较好的上行传输性能。
然而，相关技术中终端在任意时刻都只能使用一个上行载波。对于支持SUL的终端而言，终端在发起随机接入之前，需要进行载波的选择。在空口质量较差的情况下，选择使用SUL发起随机接入，在空口质量较好的情况下，选择使用一般上行载波发起随机接入。其中，终端可以通过SUL的参考信号接收功率(Reference Signal Receiving power，RSRP)门限值(threshold)来确定用于发起随机接入的上行载波。但是相关技术中，对于新加入的覆盖增强(Coverage enhancement，CE)能力的终端而言，即使空口质量差，也可以使用一般上行载波发起随机接入。因此，不具有CE能力的终端，若使用与具有CE能力的终端相同的载波门限值来选择合适的上行载波来发起随机接入，将无法实现具有CE能力终端的功能，降低了基站调度的灵活性。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种网络设备与终端的通信系统架构图。本公开提供的通信方法可以应用于图1所示的通信系统架构图中。如图1所示，网络侧设备可以基于图1所示的架构发送信令。
可以理解的是，图1所示的网络设备与终端的通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple  Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、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)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在新一代的通信技术(例如，NR)中，针对载波除包含有上行载波和下行载波对应的载波对之外，还包括有一个SUL，也可以称SUL为补充上行载波。SUL一般都部署在低频，比如，一个载波工作在3.5GHZ频段，会配置一个800MHZ的补充上行载波。配置SUL主要目的是扩展上行覆盖。通过使用低频载波提高小区边缘等功率受限区域的上行传输的性能。其中，载波对中包含的上行(UL)载波(即，一般载波)的上行带宽会比SUL的上行带宽大。因此，在空口质量较好的情况下，比如终端离无线接入网设备(基站)距离很近，终端可以使用UL载波来获得较高的速率。而在空口质量变得差的时候，由于低频载波路损较小，终端可以使用处在低频的SUL上行载波来获得较好的上行传输性能。其中，相关技术中终端在任意时刻都只能使用一个上行载波。
对于支持SUL的终端而言，终端在发起随机接入之前，需要进行UL载波和SUL载波的选择。终端可以通过UL载波和SUL载波之间选择的RSRP门限值(RSRP-thresholdSSB-SUL)来判断用于发起随机接入的载波。图2是根据一示例性实施 例示出的一种选择UL载波和SUL载波的示意图。如图2所示，当终端测量得到的同步信号参考信号接收功率(Synchronization Signal Reference Signal Received Power，SS-RSRP)小于RSRP-thresholdSSB-SUL这一阈值时，终端将使用SUL载波发起随机接入；当终端测量得到的SS-RSRP大于RSRP-thresholdSSB-SUL这一阈值时，终端将使用UL载波发起随机接入。换言之，当覆盖条件较差时，将通过使用SUL载波来增强随机接入过程中上行信道的传输。
在标准(Rel-17)讨论中，部分终端具有CE能力，可以使用盲重传的方式来提高随机接入过程中msg3这一上行传输的性能，并且CE终端上行覆盖要更强。此时，如果UL支持CE，则对于CE终端即使在覆盖较差的小区边缘位置仍然可以选择继续留在UL上发起随机接入。但是不具有CE能力的终端，若使用与具有CE能力的终端相同的载波门限值来选择合适的上行载波来发起随机接入，则可能由于信号质量太差而导致随机接入不成功。
本公开提供了一种载波确定方法，通过为CE终端和非CE终端配置不同的RSRP门限值，实现不同载波之间的负载均衡，同时减少不同载波之间的切换，降低接入时延，使得配置RSRP门限值更加灵活。
下述实施例将结合附图对配置RSRP门限值进行说明。
图3是根据一示例性实施例示出的一种载波确定方法的流程图。如图3所示，载波确定方法用于终端中，包括以下步骤。
在步骤S11中，确定终端的终端信息，并确定与终端信息对应的第一门限值。
在步骤S12中，基于第一门限值，确定用于数据传输的载波。
在本公开实施例中，终端信息可以终端类型、终端功能和终端信道状态的一种或多种。第一门限值可以是信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、信噪比(Signal-to-noise ratio，SNR)、RSRP、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)、信道质量测量值的门限值等。用于数据传输的载波可以是用于发起随机接入的载波。
终端根据自身的终端信息，确定与其终端信息对应的第一门限值。例如，若终端信息中包括终端的类型，则终端的类型可以是覆盖增强终端，或者是非覆盖增强终端。终端根据与之对应的第一门限值，选择用于数据传输的载波。
通过本公开实施例提供的载波确定方法，终端可以基于自身的终端信息，确定用于判决数据传输使用的载波。从而可以减少不同载波之间的切换，降低接入时延。
在本公开实施例中，响应于终端信息为终端类型，以两个类型终端为例，确定与终端 类型对应的第一门限值可以采用下述实施方式。
在一种实施方式中，网络设备可以为不同终端类型配置不同的第一门限值。终端可以根据自身的类型在不同的两个第一门限值中，确定与其类型对应的第一门限值。终端将测量同步信号块(Synchronization Signal and PBCH block，SSB)得到的SS-RSRP与自身对应的第一门限值进行比较，在UL载波和SUL载波中确定数据传输使用的载波。其中，终端还可以测量信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)，得到信道状态测量值，基于信道状态测量值与第一门限值进行比较，在UL载波和SUL载波中确定数据传输使用的载波。
在另一种实施方式中，网络设备可以为不同终端类型配置一个候选门限值，并且配置一个偏移值，为便于区分，将该偏移值称为第一偏移值。终端确定与其对应的第一门限值，可以采用图4所示的实施步骤。
图4是根据一示例性实施例示出的一种载波确定方法的流程图。如图4所示，载波确定方法用于终端中，包括以下步骤。
在步骤S21中，基于接收的第一指示信令或通信协议，确定候选门限值和/或第一偏移值。
在本公开实施例中，终端接收网络设备发送的第一指示信令或通信协议，并基于第一指示信令或通信协议确定第一门限值和/或第一偏移值。其中，第一指示信令可以是主信息块(Master information block，MIB)、剩余最小系统信息(Remaining minimum system information，RMSI)、其他系统信息(Other System Information，OSI)、无线资源控制(Radio Resource Contro,RRC)信令、下行控制信息(Downlink Control Information)、媒体接入控制层控制信令(Media Access Control，MAC CE)等。例如，通信协议规定第一门限值可以是一个固定的值，或者网络设备通过第一指示信令半静态或者动态地指示第一门限值。
在步骤S22中，根据终端信息，将候选门限值确定为与终端信息对应的第一门限值，或，基于候选门限值和第一偏移值，确定与终端信息对应的第一门限值。
在本公开实施例中，候选门限值可以其中任意一种终端信息，终端在确定自身的终端信息之后，确定候选门限值对应的终端信息。若候选门限值与终端的终端信息对应，则将该候选门限值确定为第一门限值。若候选门限值对应的终端信息不同于该终端的终端信息，则基于候选门限值和第一偏移值，确定与终端信息对应的第一门限值。
一种方式中，终端信息包括终端类型，终端类型包括第一终端类型和第二终端类型，第一终端类型的终端可以是不具有覆盖增强能力的终端，第二终端类型的终端可以是具有 覆盖增强能力的终端。例如，候选门限值对应不具有覆盖增强能力的终端，则不具有覆盖增强能力的终端将候选门限值确定为与之对应的第一门限值，具有覆盖增强能力的终端基于候选门限值和第一偏移值确定与之对应的第一门限值。再例如，候选门限值对应具有覆盖增强能力的终端，则具有覆盖增强能力的终端将候选门限值确定为与之对应的第一门限值，不具有覆盖增强能力的终端基于候选门限值和第一偏移值确定与之对应的第一门限值。
示例性的，若网络设备通过信令指示或通信协议确定为不具有覆盖增强能力的终端配置了第一门限值。响应于终端为不具有覆盖增强能力的终端，基于第一门限值在UL载波和SUL载波中选择用于数据传输的载波。响应于终端为具有覆盖增强能力的终端，终端可以通过网络设备的配置信令获取第一偏移值，通过计算第一门限值和第一偏移值，确定与具有覆盖增强能力的终端对应的第一门限值。例如，CE终端UL载波和SUL载波之间选择的第一门限值可以基于非CE终端UL载波和SUL载波之间选择的门限值与第一偏移值之间的差值确定。(rsrp_thresholdSSB_SUL for CE UE＝rsrp_ThresholdSSB_SUL for non CE UE-offset)。终端将测量得到的SS-RSRP与自身类型对应的第一门限值比较，在UL载波和SUL载波中确定数据传输使用的载波。
在本公开又一些实施例中，覆盖增强终端在确定用于数据传输使用的载波之后，还可以确定是否在该载波中发起重传请求，以进行覆盖增强。其中，覆盖增强终端可以根据第二门限值确定是否在该载波中发起重传请求。进一步基于该第二门限值确定第一门限值，可参见图5所示的实施步骤。
图5是根据一示例性实施例示出的一种载波确定方法的流程图。如图5所示，载波确定方法用于终端中，包括以下步骤。
在步骤S31中，基于接收的第一指示信令或通信协议，确定第二门限值与第二偏移值。
其中，第二门限值用于确定是否发起重传请求。重传请求可以是消息3(msg3)的盲重传请求。
在步骤S32中，基于第二门限值与第二偏移值，确定终端信息对应的第一门限值。
在本公开实施例中，若网络设备为终端配置了第二门限值，且对于不同终端类型配置了不同的偏移值，则终端可以基于第二门限值和偏移值，确定与之对于的第一门限值。其中偏移值可以是由协议规定的，也可以是网络设备动态指示的，在此不做具体限定。
示例性的，若网络设备为UL载波和SUL载波分别配置第二门限值，以其中一个载波配置的第二门限值为例，若终端信息包括终端类型。终端确定第二门限值，并确定与终端类型对应的偏移值，基于对应的偏移值确定对应类型的终端用于选择用于数据传输的载波 的第一门限值。当然，在本公开中，配置的偏移值还可以是与第二门限值相关的其他参数，在此不一一举例说明。
在本公开一些实施例中，若终端信息包括第一终端类型和第二终端类型。其中，第一终端类型为具有覆盖增强能力的终端类型，第二终端类型为不具有覆盖增强能力的终端类型。则如图6所示，第一终端类型对应的第一门限值小于第二终端类型对应的第一门限值。其中，图6是根据一示例性实施例示出的一种载波确定方法中不同第一门限值的示意图。
在本公开实施例中，终端基于确定的载波进行数据传输，还可以进一步基于第二门限值确定是否发起重传请求。图7是根据一示例性实施例示出的一种载波确定方法中不同第二门限值的示意图。如图7所示，终端基于接收的第二指示信令或通信协议确定第二门限值，不同的第二门限值对应不同的载波。其中第二门限值用于确定是否发起重传请求。
例如，覆盖增强终端测量得到的SS-RSRP的值大于覆盖增强终端对应的第一门限值，并且小于非覆盖增强终端(即，不支持覆盖增强能力的终端)对应的第一门限值，CE终端则发起msg3的盲重传请求。
再比如，覆盖增强终端测量得到的SS-RSRP的值小于SUL载波的第二门限值，覆盖增强终端则在SUL载波上发起msg3的盲重传请求。或者，覆盖增强终端测量得到的SS-RSRP的值大于覆盖增强终端对应的载波选择第一门限值，且小于UL载波的第二门限值，覆盖增强终端则在UL载波上发起msg.3的盲重传请求。
下述实施例将对确定第二门限值进行说明。
在本公开一些实施例中，终端接收的第二指示信令确定第二门限值，或根据通信协议确定第二门限值。其中，第二门限值用于确定是否发起重传请求。不同的第二门限值对应不同的载波。
在本公开实施例中，第二指示信令可以是系统消息(MIB)、RMSI、OSI、RRC、MAC CE、下行控制信息(Downlink Control Information，DCI)等信令。
在本公开另一些实施例中，第二指示信令或通信协议还包括第三偏移值或第四偏移值。第二门限基于第一门限值和第三偏移值确定的。或，第二门限值基于第一门限值和第四偏移值确定的。第三偏移值和第四偏移值对应不同的载波。例如，第三偏移值对应UL载波，第四偏移值对应SUL载波。
示例性的，网络设备为终端配置一个相对于UL载波的第三偏移值，则终端可以基于覆盖增强终端或非覆盖增强终端的第一门限值与第三偏移值确定UL载波的第二门限值。或者网络设备配置一个相对于覆盖增强终端的第一门限值的相关参数，终端根据该相关参数以及基点确定第三偏移值，再基于覆盖增强终端或非覆盖增强终端的第一门限值，以及 或第三偏移值确定第二门限值。该第二门限值用于覆盖增强终端确定是否msg3重传请求。
又一实施例中，SUL载波上发起msg.3盲重传请求的第二门限值，基于UL载波上的msg.3盲重传请求第二门限值及相应的偏移值确定。
再一实施例中，UL载波上发起msg.3盲重传请求的第二门限值，基于SUL载波上的msg.3盲重传请求第二门限值及相应的偏移值确定。
在本公开一些实施例中，若第二门限值为终端在主载波(UL)上确定是否msg3重传请求的门限值，终端信息包括终端类型，则第二门限值大于或等于第一终端类型(即，覆盖增强终端)对应的第一门限值，且第二门限值大于或等于第二终端类型(即，非覆盖增强终端)对应的第一门限值。
若第二门限值为终端在辅载波(SUL)上确定是否msg3重传请求的门限值，第二门限值小于或等于第一终端类型对应的第一门限值。
在本公开实施例中，若终端确定的SS-RSRP测量值大于或等于第一门限值，确定使用主载波进行数据传输。若终端确定的SS-RSRP测量值小于或等于门限值，确定使用辅载波进行数据传输。
在本公开实施例中，终端通过比较获得的SS-RSRP测量值与第二门限值，确定是否发起msg3的重传请求。可参见图8所示的实施步骤。
图8是根据一示例性实施例示出的一种载波确定方法的流程图。如图8所示，载波确定方法用于终端中，包括以下步骤。
在步骤S41中，确定信道测量值以及用于数据传输的载波。
在步骤S42中，响应于信道测量值小于与载波对应的第二门限值，基于相应载波发起重传请求。
在本公开一些实施例中，终端基于SS-RSRP测量值与第一门限值进行比较，确定用于数据传输的载波后，还可以将SS-RSRP测量值与第二门限值进行比较，进一步确定是否在该载波上发起msg3的重传请求。若，SS-RSRP测量值小于与该载波对应的第二门限值，基于该载波发起msg3的重传请求。
基于相同/相似的构思，本公开实施例还提供一种载波确定方法。

示例性的，若网络设备通过信令指示或通信协议确定为不具有覆盖增强能力的终端配置了第一门限值，则，响应于终端为不具有覆盖增强能力的终端，基于第一门限值在UL载波和SUL载波中选择用于数据传输的载波。响应于终端为覆盖增强终端，终端可以通过网络设备的配置信令获取第一偏移值，通过计算第一门限值和第一偏移值，确定与覆盖增强终端对应的第一门限值。例如，CE终端UL载波和SUL载波之间选择的第一门限值可以基于非覆盖增强终端UL载波和SUL载波之间选择的门限值与第一偏移值之间的差值确定。(rsrp_thresholdSSB_SUL for CE UE＝rsrp_ThresholdSSB_SUL for non CE UE-offset)。终端将测量得到的SS-RSRP与自身类型对应的第一门限值比较，在UL载波和SUL载波中确定数据传输使用的载波。
在本公开实施例中，网络设备还可以为覆盖增强终端配置第二门限值，且对于不同终端类型配置了不同的偏移值，第二门限值用于终端确定是否发起重传请求，以进行覆盖增强。其中偏移值可以是基于某个基点以及第一门限值相关参数确定的，也可以是网络设备动态指示的，在此不做具体限定。
示例性的，网络设备为UL载波和SUL载波分别配置第二门限值，以其中一个载波配置的第二门限值为例。终端确定第二门限值，并确定与其终端信息对应的偏移值，基于对应的偏移值确定终端用于数据传输的载波的第一门限值。当然，在本公开中，配置的偏移值还可以是与第二门限值相关的其他参数，在此不一一举例说明。
在本公开一些实施例中，若终端的类型包括第一终端类型和第二终端类型。其中，第 一终端类型为覆盖增强能力的终端类型，第二终端类型为不具有覆盖增强能力的终端类型。第一终端类型对应的第一门限值小于第二终端类型对应的第一门限值。其中，
在本公开实施例中，终端基于确定的载波用于数据传输，还可以进一步基于第二门限值确定是否发起重传请求。终端基于接收的第二指示信令或通信协议确定第二门限值，不同的第二门限值对应不同的载波。其中第二门限值用于确定是否发起重传请求。
例如，终端测量得到的SS-RSRP的值大于覆盖增强终端对应的第一门限值，并且小于非覆盖增强终端(即，不支持覆盖增强能力的终端)对应的第一门限值，可以将SS-RSRP的值与第二门限值比较，确定是否发起msg3的盲重传请求。
再比如，覆盖增强终端测量得到的SS-RSRP的值小于SUL载波的第二门限值，覆盖增强终端则在SUL载波上发起msg3的盲重传请求。或者，覆盖增强终端测量得到的SS-RSRP的值大于覆盖增强终端对应的载波选择第一门限值，且小于UL载波的第二门限值，覆盖增强终端则在UL载波上发起msg.3的盲重传请求。
下述实施例将对确定第二门限值进行说明。
图10是根据一示例性实施例示出的一种载波确定方法的流程图。如图10所示，载波确定方法用于网络设备中，包括以下步骤。
在步骤S61中，发送第二指示信令。
其中，第二指示信令包括第二门限值。第二门限值用于确定是否发起重传请求。第二指示信令可以是MIB、RMSI、OSI、RRC、MAC CE、DCI等信令。
在本公开一些实施例中，网络设备可以为终端不同的载波配置不同的第二门限值。
在本公开另一些实施例中，第二指示信令或通信协议还包括第三偏移值或第四偏移值。第二门限基于第一门限值和第三偏移值确定的。或，第二门限值基于第一门限值和第四偏移值确定的。第三偏移值和第四偏移值对应终端信息不同。例如，第三偏移值对应第一终端类型，则可以基于第一终端类型对应的第一门限值确定第二门限值。第四偏移值对应第二终端类型，则可以基于第二终端类型对应的第一门限值确定第二门限值
示例性的，网络设备为终端配置一个相对于UL载波的第三偏移值，则终端可以基于覆盖增强终端或非覆盖增强终端的第一门限值与第三偏移值确定UL载波的第二门限值。或者网络设备配置一个相对于覆盖增强终端的第一门限值的相关参数，终端根据该相关参数以及基点确定第三偏移值，再基于覆盖增强终端或非覆盖增强终端的第一门限值，以及或第三偏移值确定第二门限值。该第二门限值用于终端确定是否msg3重传请求。
在本公开一些实施例中，若第二门限值为终端在主载波(UL)上确定是否msg3重传请求的门限值，终端信息包括终端类型，则第二门限值大于或等于第一终端类型(即，覆 盖增强终端)对应的第一门限值，且第二门限值大于或等于第二终端类型(即，非覆盖增强终端)对应的第一门限值。
若第二门限值为终端在辅载波(SUL)上确定是否msg3重传请求的门限值，第二门限值小于或等于第一终端类型对应的第一门限值。
在本公开实施例中，若终端确定的SS-RSRP测量值大于或等于第一门限值，确定使用主载波(UL)进行数据传输。若终端确定的SS-RSRP测量值小于或等于门限值，确定使用辅载波(SUL)数据传输。
在本公开实施例中，终端通过比较获得的SS-RSRP测量值与第二门限值，确定是否发起msg3的重传请求。
例如，终端基于SS-RSRP测量值与第一门限值进行比较，确定数据传输的载波后，还可以将SS-RSRP测量值与第二门限值，进一步确定是否在该载波上发起msg3的重传请求。若，SS-RSRP测量值小于与该载波对应的第二门限值，基于该载波发起msg3的重传请求。
