Description

一种载波保持方法/装置/设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种载波保持方法/装置/设备及存储介质。
背景技术
在通信系统中，为了支持终端设备与终端设备之间的直接通信，以及提升通信效率，引入了侧行链路sidelink和载波聚合，其中，sidelink的资源分配方式为网络动态调度资源或终端设备在网络广播的资源池中自主选择资源。以及，在通信系统中还引入了载波聚合(Carrier Aggregation，CA)技术，以有效提高上下行传输速率。
相关技术中，长期演进车联网(Long Term Evolution Vehicle to everything，LTE V2X)和新空口(New Radio，NR)sidelink都可以支持侧行链路载波聚合技术，其中，针对自主选择资源方式而言，LTE V2X系统和NR sidelink系统中的终端设备都可以做载波的选择和重选。以及，在重选载波时，终端设备具体还会判断其是否要重选到当前工作载波上。其中，LTE V2X系统中一个载波支持配置一个资源池，终端设备可以基于测量到的某一载波对应配置的资源池的信道占用率(channel busy ratio，CBR)与保持门限值之间的大小关系来确定是否重选至当前工作载波。
但是，相关技术中，在NR sidelink系统中，一个载波可支持配置多个资源池，其中，针对一个资源池会对应测量出一个CBR，则会使得一个载波对应有多个CBR，此时在确定是否重选至当前工作载波时，无法确定具体使用当前工作载波的哪一个资源池对应的CBR与保持门限值进行比较，从而导致NR sidelink系统中的终端设备无法判断是否要重选至当前工作载波。
发明内容

为了便于理解，首先介绍本申请涉及的术语。
1、侧行链路(Sidelink，SL)
Sidelink通信分为两种模式，一种叫做终端设备之间的发现(dicovery)，另外一种叫做终端设备之间的通信(communication)。Sidelink使用了上行资源以及与蜂窝网络(LTE)类似的上行物理信道进行数据交互传输。
2、信道占用率(Channel Busy Ratio，CBR)
CBR是衡量一个频段上的子信道(sub-channel)被占用情况的一个参数，终端设备在发送资源池上根据网络侧的配置做CBR测量，CBR值越低表明占用该资源池的子信道发数据的终端设备越少，选择这个资源池发数据的冲突性越低。
3、载波聚合(Carrier Aggregation，CA)
可以将多个载波(ComponentCarrier，CC)聚合在一起，实现更高的传输带宽，有效提高了上下行传输速率，终端设备可以根据自己的能力大小决定最多可以同时利用几个载波进行上下行传输。
为了更好的理解本公开实施例公开的一种指示的方法，下面首先对本公开实施例适用的通信系统进行描述。
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个终端设备12为例。
需要说明的是，本公开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、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网 络设备11可以为演进型基站(evolved NodeB，eNB)、发送接收点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开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。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
图2为本公开实施例所提供的一种载波保持方法的流程示意图，应用于终端设备，其中，如图2所示，该载波保持方法可以包括以下步骤：
步骤201、获取网络设备配置的用于保持载波的保持门限值。
其中，本公开的方法可以应用至NR sidelink系统中。
在本公开的一个实施例之中，该保持门限可以作为一个衡量标准，用于确定是否保持(或重选)到当前工作载波上。其中，关于该保持门限值具体如何确定是否保持(或重选)到当前工作载波上的详细介绍会在后续实施例说明
以及，在本公开的一个实施例之中，该获取网络设备配置的用于保持载波的保持门限值，可以包括以下至少一种：
获取网络设备针对各个小区分别配置的保持门限值(即不同小区对应不同的保持门限值)；
获取网络设备针对各个带宽部分(Bandwidth Part，BWP)分别配置的保持门限值(即不同BWP对应不同的保持门限值)；
获取网络设备针对各个频率分别配置的保持门限值(即不同频率对应不同的保持门限值)；
获取网络设备针对终端设备配置的保持门限值；其中，该终端设备对应的保持门限值和其他终端设备对应的保持门限值由网络设备分别对应配置(即不同终端设备对应不同的保持门限值)；
获取网络设备针对各个逻辑信道优先级分别配置的保持门限值(即不同小区对应不同的保持门限值)。
需要说明的是，在本公开的一个实施例之中，上述的不同粒度之间还可以两两组合、三三组合、四四组合等。示例的，以上述不同粒度两两组合为例进行说明，假设“各个小区”和“各个逻辑信道优先级”组合，则此时，终端设备会获取网络设备针对各个小区的各个逻辑信道优先级分别配置的保持门限值，其中，不同小区的不同逻辑信道优先级对应所配置的保持门限值不同。示例的，如小区#1中的逻辑信道第一优先级配置的保持门限值为A，小区#2中的逻辑信道第一优先级配置的保持门限值为B。
以及，在本公开的一个实施例之中，上述的保持门限值可以是网络设备通过专用无线资源控制(Ratio Resource Control，RRC)信令配置和/或系统信息块(System Information Block，SIB)配置的；在本公开的另一个实施例之中，上述的保持门限值也可以是预配置的。
步骤202、响应于终端设备触发了载波重选，确定终端设备的当前工作载波对应的至少一个第一资源池，该第一资源池为当前工作载波上的包括了可用于重选的候选资源的资源池。
其中，在本公开的一个实施例之中，该载波重选可以是由混合自动重传请求应答(Hybrid Automatic Retransmission Request，HARQ)进程触发的，或者，也可以是由逻辑信道触发的。
以及，在本公开的一个实施例之中，上述的资源池具体可以是网络设备预配置的，其中，一个载波可以配置至少一个资源池，该资源池中包括有sidelink传输所用的资源(如时频资源)以及传输相关的参数等，并且，在资源池中的频域资源可以以子信道进行划分，其中，资源池中的子信道大小可以为：10，15，20，25，50，75或100(物理资源块(Physical Resource Block，PRB)等，该子信道可以为物理信道。
以及，在本公开的一个实施例之中，当触发了载波重选之后，终端设备一般会确定出可用于重选的候选资源，以便后续能够重选到该候选资源上进行通信。其中，该候选资源可以是属于源资源池，也可以属于其他资源池中。
进一步地，在本公开的一个实施例之中，当触发了载波重选且确定出候选资源后，终端设备会基于候选资源确定出当前工作载波对应的至少一个第一资源池，该第一资源池具体为：当前工作载波上的包括了可用于重选的候选资源的资源池，以便后续可以基于该第一资源池的CBR测量结果来确定是否要重选到当前工作载波上。
在本公开的一个实施例中，载波重选可以指的是小区重选，即在采用不同载波的不同小区之间进行重选。另外，工作载波可以指的是终端设备与其服务小区进行通信所采用的载波。
步骤203、基于第一资源池的CBR测量结果确定终端设备是否要重选到当前工作载波上。
其中，在本公开的一个实施例之中，资源池的CBR测量结果具体为一CBR测量值，其可以用于体现一个资源池中的子信道(sub-channel)被占用情况。其中，当CBR测量结果越低，说明占用该资源池的子信道终端设备越少，则重选该资源池传输数据的冲突性越低，当CBR测量结果越高，说明该资源池中用于传输数据的子信道越多，则重选该资源池传输数据时发生冲突性越高。
需要说明的是，在本公开的一个实施例之中，上述的资源池的CBR测量结果可以是由物理层(Physics，PHY)/媒体接入控制层(Media Access Control，MAC)层计算所得的。以及，在V2X系统中，对于物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)而言，资源池的CBR可以是资源池中侧链接收信号强度指示器(sidelink received signal strength indicator，S-RSSI)超过-94dBm阈值的子信道的比例；对于具有非相邻控制和数据资源的物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)而言，资源池的CBR可以是资源池中S-RSSI超过-94dBm阈值的资源(2个PRB对)的比例。
以及，关于上述步骤中的具体如何基于第一资源池的CBR测量结果确定终端设备是否要重选到当前工作载波上的具体实现方式会在后续实施例进行详细说明。
综上所述，在本公开实施例提供的载波保持方法之中，终端设备先获取网络设备配置的用于保持载波的保持门限值，之后，响应于终端设备触发了载波重选，确定终端设备的当前工作载波对应的至少一个第一资源池，该第一资源池为当前工作载波上的包括了可用于重选的候选资源的资源池；最后再基于第一资源池的CBR测量结果确定终端设备是否要重选到当前工作载波上。由此可知，本公开中，当当前工作载波配置了多个资源池时，终端设备可以基于当前工作载波对应的包括了可用于重选的候选资源的至少一个第一资源池的CBR测量结果，来确定终端设备是否要重选到当前工作载波上，从而本公开的方法可以适用于“一 个载波支持配置多个资源池”这一情形，也即是，本公开的方法可以适用于NR sidelink系统的终端设备判断是否要重选至当前工作载波。
此外，需要说明的是，终端设备当前可能使用了多个资源池，由此可能会出现当前使用的多个资源池中的部分资源池同时分别触发了资源(或载波)重选流程，基于此，针对每个资源池对应的资源(或载波)重选流程均可以通过执行本公开所提供的方法来判断是否可以保持在当前工作载波上。
图3a为本公开实施例所提供的一种载波保持方法的流程示意图，应用于终端设备，其中，如图3a所示，该一种载波保持方法可以包括以下步骤：
步骤301a、从至少一个第一资源池中选择一个资源池作为第二资源池。
其中，当第一资源池的数量包括多个时，在本公开的一个实施例之中，终端设备可以从多个第一资源池中随机选择一个资源池作为第二资源池。在本公开的另一个实施例之中，终端设备可以将多个第一资源池中CBR测量结果最小的资源池选择为第二资源池。在本公开的又一个实施例之中，终端设备也可以将多个第一资源池中CBR测量结果最大的资源池选择为第二资源池。
步骤302a、响应于针对第二资源池的CBR测量结果小于或者等于保持门限值，确定终端设备重选到当前工作载波上。
其中，在本公开的一个实施例之中，当第二资源池的CBR测量结果小于或等于保持门限值，则说明该第二资源池的CBR测量结果较低，也即是，该第二资源池中用于传输数据的子信道较少，此时，若重选该第二资源池传输数据时发生冲突的可能性也较低。由此确定该第二资源池具备重选资格，进一步地，由于第二资源池是配置在当前工作载波上的，则可以确定该当前工作载波也具备重选资格，此时终端设备可以确定其重选到当前载波上(即继续保持在当前工作载波上)，而无需再重选到其他载波上，则可以减少不必要的重选步骤，提高通信效率。
以及，需要说明的是，在本公开的一个实施例之中，若保持门限值的配置方法不同，则本步骤302a中的第二资源池的CBR测量结果与保持门限值的比较方法也会有所不同。具体的，在本公开的一个实施例之中，若保持门限值为针对各个小区或针对各个BWP或针对各个频率或针对终端设备配置的，则本步骤302a中具体是将第二资源池的CBR测量结果与第二资源池对应的保持门限值作比较。
示例的，在本公开的一个实施例之中，若保持门限值为针对各个小区设置的，则具体是当第二资源池的CBR测量结果小于或等于了第二资源池所属小区对应的保持门限值时，确定终端设备重选到当前工作载波上。或者，若保持门限值为针对各个BWP设置的，则具体是当第二资源池的CBR测量结果小于或等于了第二资源池所属BWP对应的保持门限值时，确定终端设备重选到当前工作载波上。
在本公开的另一个实施例之中，响应于保持门限值为针对各个逻辑信道优先级分别配置的，则是将第二资源池的CBR测量结果与每一个有待传数据且触发了载波重选的逻辑信道的优先级对应的保持门限值进行比较。
示例的，假设保持门限值为针对各个逻辑信道优先级分别配置的，其中，假设逻辑信道优先级包括第一优先级、第二优先级、第三优先级，其中，针对第一优先级、第二优先级、第三优先级配置的保持门限值分别为：保持门限值#1、保持门限值#2、保持门限值#3。此时，若逻辑信道#1和逻辑信道#2触发了载波重选，同时，逻辑信道#1、逻辑信道#2均有待传数据，其中，逻辑信道#1的优先级为第一优先级、逻辑信道#2的优先级为第二优先级、逻辑信道#3的优先级为第三优先级。则具体是当第二资源池的CBR测量结果小于或等于了有待传数据且触发了载波重选的逻辑信道#1的第一优先级对应的CBR门限值#1，同时，还小于或等于了有待传数据且触发了载波重选的逻辑信道#2的第二优先级对应的CBR门限值#2 时，才确定终端设备重选到当前工作载波上。
在本公开的又一个实施例之中，若保持门限值为针对各个小区各个逻辑信道优先级分别配置的，具体是将第二资源池的CBR测量结果与第二资源池所属小区中每一个有待传数据且触发了载波重选的逻辑信道的优先级对应的CBR门限值的资源池进行比较。
