Description

无线通信的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种无线通信的方法和装置。
背景技术
目前，已知一种侧行链路通信技术，即终端设备之间使用侧行链路直接进行通信。例如，设备到设备(device to device，D2D)通信、车与车(vehicle to vehicle，V2V)通信、车与基建或网络(vehicle to infrastructure/network，V2I/N)通信车与任何事物相通信V2X(vehicle to everything，V2X)。
基于侧行链路通信时，对资源的调度通常有两种方式：一种是基于调度的方式，即网络设备为终端设备分配侧行链路的资源，该资源可以是属于一个资源池的资源，也可以是不属于任何资源池的资源；另一种是基于检测的调度方式，即终端设备对网络设备分配的资源池中的资源进行检测，并使用可供使用的资源进行侧行链路通信，其中可供使用的资源可以为终端设备检测出来的未被占用的资源，或者抢占其他终端设备使用的资源。其中，未被占用，表示检测出来的该资源上的信号强度低于某个门限值。
为了提高网络设备分配资源的有效性，终端设备会向网络设备上报资源池中的信道占用率(channel occupancy ratio，CR)，从而网络设备可以根据信道占用率获知资源池的拥塞状况，进而可以对资源池进行拥塞控制。
传统技术中的信道占用率只能反映资源池中的被占用的子信道与所有信道的比例，导致网络设备对资源池的拥塞控制的效果较差。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
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频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)移动通信系统或新无线接入技术(new radio access technology，NR)。其中，5G移动通信系统可以包括非独立组网(non-standalone，NSA)和/或独立组网(standalone，SA)。
本申请提供的技术方案还可以应用于机器类通信(machine type communication，MTC)、机器间通信长期演进技术(Long Term Evolution-machine，LTE-M)、设备到设备(device to device，D2D)网络、机器到机器(machine to machine，M2M)网络、物联网(internet of things，IoT)网络或者其他网络。其中，IoT网络例如可以包括车联网。其中，车联网系统中的通信方式统称为车到其他设备(vehicle to X，V2X，X可以代表任何事物)，例如，该V2X可以包括：车辆到车辆(vehicle to vehicle，V2V)通信，车辆与基础设施(vehicle to infrastructure，V2I)通信、车辆与行人之间的通信(vehicle to pedestrian，V2P)或车辆与网络(vehicle to network，V2N)通信等。
本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统等。本申请对此不做限定。
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，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5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天 线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请实施例对此不做限定。

本申请实施例中，所有“大于”可以替换为“大于或等于”；所有“小于”可以替换为“小于或等于”。
为便于理解本申请，在介绍本申请实施例之前，先对本申请中涉及到的侧行链路做简单介绍。
侧行链路(sidelink，SL)，也可以称为边链路控制信息。其中，边链路或侧行链路指终端设备之间的传输链路。在SL中，终端设备之间的数据传输不经过网络设备进行中转。
图1示出了本申请实施例提供的技术方案的应用场景的示意图，如图1所示，基于侧行链路通信技术的应用场景中可以至少包括一个网络设备111、一个终端设备112和另一个终端设备113。
本申请实施例对基于侧行链路直接进行通信的技术不作具体限定。例如，可以是设备到设备(device to device，D2D)的通信、车与车(vehicle to vehicle，V2V)的通信、车 与行人(vehicle to pedestrian，V2P)的通信或车与基建/网络(vehicle to infrastructure/network，V2I/N)的通信。其中，V2V、V2P以及V2I/N统称为V2X(vehicle to everything，V2X)，即车与任何事物相通信。
在图1中，网络设备111可以与终端设备112、终端设备113进行通信，终端设备112与终端设备113也可以相互通信。例如，网络设备111、终端设备112、终端设备113之间通信时可以使用蜂窝链路的频谱。或者，也可以使用5.9GHz附近的智能交通频谱进行通信。此外，各设备相互通信的技术可以基于LTE协议进行增强，也可以基于D2D技术进行增强。
应理解，图1中仅为便于理解，示意性示出了网络设备111、终端设备112和终端设备113，但这不应对本申请构成任何限定。例如，本申请实施例的应用场景可以是有网络设备覆盖的场景，也可以是无网络覆盖的场景。在不同应用场景下，可以包含更多数量的网络设备，也可以包含更多数量的终端设备，本申请对此不做限定。
作为本申请实施例的另一个应用场景，在图1的应用场景中可以包括一个或多个全球导航卫星系统(global navigation satellite system，GNSS)，GNSS可以与网络设备111、终端设备112、终端设备113中的任一设备进行通信，GNSS为与其通信的设备提供定位与授时的信息。在图1的应用场景中还可以包括一个或多个路侧单元(road side unit，RSU)，RSU可以和一个或多个终端设备通信，也可以和一个多个网络设备111通信。其中，RSU在功能上既可以是一个车载设备的功能，也可以是eNB或gNB设备的功能，还可以同时具备车载设备和eNB设备的功能。
在传统的侧行链路通信技术中，终端设备进行资源传输前，需要对资源进行检测，同时对该资源池中的信道状况作出判断，确定资源池是否拥塞。终端设备可以上报该资源池的拥塞情况，使得网络设备获知资源池当前的子信道使用状况，进行一定的拥塞控制，从而保证侧行链路的服务质量(quality of service,QoS)。通常，有两种判断准则用来评价QoS，一种是信道繁忙率(channel busy ratio，CBR)，另一种是CR。通常子帧n上的CR被定义为：在该子帧[n-a,n-1]上所有用于传输的信道数目以及在该子帧[n,n+b]中所调度或者所授权的用于传输的信道除以所有在子帧[n-a,n+b]被配置在该资源池中的子信道数目。子帧n的CBR定义为：终端设备在该子帧[n-100,n-1]上所测量的资源池中的子信道上的侧行链路接收信号强度指示超出一个预先配置的门限时。
当终端设备上报CBR或CR后，网络设备为了避免拥塞可以进行拥塞控制处理，例如，网络设备可以通过重新配置扩大该资源池所包含的资源。
本申请中，拥塞处理包括下述至少一项：调整资源池所包含的子信道的数量；调整侧行链路上被调度进行传输的数据的调制解调方案(modulation and coding scheme,MCS)或MCS的范围；调整侧行链路上数据传输的重传数目(retransmission number)；调整侧行链路上允许的终端设备的功率值；调整用于占用率比较的门限值。
作为一个示例，当CBR或CR上报资源池较拥塞，即繁忙率或占用率较高时，网络设备可以提高资源池所包含的子信道数；当CBR或CR上报资源池较拥塞，即繁忙率或占用率较高时，网络设备可以减少允许的MCS的范围或者限制允许的MCS的范围到比较低阶的MCS，其中，比较低阶的MCS可以为一个或者多个MCS；当CBR或CR上报资源池较拥塞，即繁忙率或占用率较高时，网络设备可以限制侧行链路上数据传输的重传数 目到一个较小的值，或者，减小侧行链路上数据传输的重传数目；当CBR或CR上报资源池较拥塞，即繁忙率或占用率较高时，网络设备可以减小侧行链路上允许的终端设备的最大功率值。
然而在传统的侧行链路通信技术中，网络设备根据CR只能获知所有数据在信道中的占用情况，当侧行链路资源池发生信道拥塞时，网络设备不能更有针对性地对发生拥塞的数据进行有效控制。
本申请提出了一种无线通信的方法，该方法能够更有针对性地对侧行链路通信过程中的拥塞进行控制，下面结合附图2详细说明本申请实施例提供的方法。
图2示出了根据本申请实施例的无线通信的方法的示意性流程图。图2的方法200包括步骤S210至步骤S230，下面对这些步骤进行详细说明。
S210，终端设备确定第一类型的数据在侧行链路资源池的第一信道占用率，第一信道占用率为第一类型的数据占用的子信道与侧行链路资源池中的所有子信道之间的比例，或第一信道占用率为第一类型的数据占用的子信道与侧行链路资源池中的所有被占用的子信道之间的比例。
本申请实施例中，终端设备获取来自其他终端设备的侧行链路控制信息，其他终端设备的侧行链路控制信息包括指示信息，指示信息用于指示其他终端设备的数据为第一类型。
本申请实施例中，对第一类型的数据的划分不做具体限定。例如，第一类型的数据可以为预设的一个优先级对应的数据，或者第一类型的数据可以为预设的一个优先级范围对应的数据。
作为一个示例，第一类型的数据为预设的一个优先级对应的数据，采用服务质量(Quality of Service，QoS)级别为每包优先权(ProSe Per Packet Priority，PPPP)定义第一类型的数据的优先级；还可以采用QoS级别为N个服务质量索引(N QoS index，NQI)定义第一类型的数据的优先级，其中N为正整数；还可以采用QoS级别为别的索引标识的。
作为另一个示例，第一类型的数据还可以为预设的一个优先级范围对应的数据。例如，采用QoS级别范围为PPPP范围定义第一类型的数据的优先级，或采用QoS级别范围为NQI范围定义第一类型的数据的优先级。
需要说明的是，QoS级别范围指示可以是根据QoS级别范围标识(index或identification(ID))。存在QoS级别范围index与对应的QoS级别起始～结束之间的匹配关系(mapping relationship)或对应关系(correspondence relationship)。例如，QoS级别范围为range1与QoS级别PPPP1～PPPP3相匹配或对应；QoS级别范围为range2与QoS级别PPPP4～PPPP6相匹配或对应；QoS级别范围为range3与QoS级别PPPP7～PPPP9相匹配或对应。又例如，QoS级别范围为range 1与QoS级别NQI1～NQI3相匹配或对应；QoS级别范围为range 2与QoS级别NQI4～NQI6相匹配或对应；QoS级别范围为range 3与QoS级别NQI7～NQI9相匹配或对应。上述匹配关系被预配置，或者被网络设备通过信令进行配置。网络设备通过信令进行配置，包括基站通过RRC信令，MAC信令或物理层信令中至少一种配置给终端设备。
应理解，在本实施例中第一信道占用率为一个周期内检测到的一个QoS范围内被占 用的子信道与该周期内所有子信道的比例；或者，第一信道占用率为一个周期内检测到的一个QoS范围内被占用的子信道与该周期内检测到的所有被占用的子信道的比例。其中，上述周期可以是网络设备通过信令进行配置的。所述一个周期也可以理解为一个时间段。
可选地，在一些实施例中，第一类型的数据为侧行链路模式1对应的数据，或者第一类型的数据为侧行链路模式2对应的数据；其中，侧行链路模式1为侧行链路资源由网络设备进行调度，侧行链路模式2为侧行链路资源由终端设备从侧行链路资源池中自主确定的。
可选地，在一些实施例中，第一类型的数据还可以为周期性数据，或者还可以为非周期性数据。
S220，终端设备向网络设备发送该第一信道占用率。

在本申请实施例中，终端设备向网络设备发送第一信道占用率和第二信道占用的发送顺序不作具体限定。例如，可以是终端设备向网络设备同时发送第一信道占用率和第二信道占用率。或者，也可以是按照先后顺序发送第一信道占用率和第二信道占用率，比如终端设备向网络设备可以先发送第一信道占用率，再发送第二信道占用率；再比如终端设备向网络设备先发送第二信道占用率，再发送第一信道占用率。
本申请实施例中，对终端设备向网络设备发送该第一信道占用率的发送方式不做具体限定。例如，对第一信道占用率的发送可以是周期性触发的，即终端设备每间隔固定时间段向网络设备发送第一信道占用率。或者，对第一信道占用率的发送还可以是基于目标事件触发的，即目标事件发生时立即触发终端设备向网络设备发送第一信道占用率。
应理解，本申请实施例中周期性触发或者基于目标事件触发的发送方式，可以是由网络设备配置的，即该网络设备可以向终端设备发送配置信息，该配置信息包含：该第一信道占用率的上报是周期性触发的，或是基于目标事件触发的。
本申请实施例中，对目标事件的定义不做具体限定。例如，目标事件可以包括以下事件中的至少一种：第一信道占用率大于第一阈值；第二信道占用率小于第二阈值，第二信道占用率是侧行链路资源池中的被占用的子信道与侧行链路资源池中的所有子信道的比例；第一信道占用率小于第三阈值，第二信道占用率小于第二阈值；或者，在资源池的信道繁忙率大于第五阈值的情况下，第一信道占用率大于第一阈值。
S230，网络设备接收终端设备发送的第一信道占用率，网络设备根据该第一信道占用 率对侧行链路资源池进行拥塞控制。
现有技术中，终端设备通过侧行链路向网络设备上报整体数据的信道占用率，网络设备并不清楚各种类型的数据在信道或子信道中的占用情况，当资源池发生拥塞时网络设备不能有效地进行拥塞控制。与现有技术不同，本申请实施例中，终端设备通过侧行链路向网络设备发送第一类型的数据的信道占用率，网络设备可获知第一类型的数据在信道或子信道中的占用情况，使得网络设备更有针对性地对资源池中的拥塞进行控制，从而提高侧行链路资源池拥塞控制的质量。
