Description

资源选择的方法和装置

技术领域
本申请涉及通信领域，并且更具体地，涉及一种资源选择的方法和装置。
背景技术
侧行链路(sidelink，SL)通信可以支持终端设备之间的直接通信，即用户数据直接在终端设备之间传输，可以避免蜂窝通信中用户数据经过网络中转传输，从而可以降低传输时延并且缓解网络负载。
目前，多个侧行链路设备以组(Group)为单位运行的机制能够降低时延、提高资源分配效率以及减少不同SL传输的干扰。其中，在以Group为单位运行的机制中，组间的资源需要通过组头(group header，GH)来为整个Group竞争或协商得到，而由于GH所处的位置不同，会导致竞争得到的资源结果相差较大。在GH分配组内SL传输资源时有些资源对该Group的组内成员(group member，GM)来说并不一定适合，可能会存在GH分配的资源存在组间干扰的影响。同时，如果SL传输中以周期性业务传输为主，这种干扰的存在则会对通信性能产生很大影响。

应理解，图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括核心网设备105以及在图1中未画出的无线中继设备和无线回传设备。本申请的实施例对该移动通信系统中包括的网络设备和终端设备的数量不做限定。
在移动通信系统100中，本申请实施例中的终端设备102、终端设备103也可以称为终端、终端设备、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑，还可以是应用于虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、运输安全(transportation safety)、智慧城市(smart city)以及智慧家庭(smart home)等场景中的无线终端。本申请中将前述终端设备及可应用于前述终端设备的芯片统称为终端设备。应理解，本申请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。
本申请实施例中的网络设备101可以是用于与终端设备通信的设备，该网络设备可以是基站、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)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，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，对网络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，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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通信(global system formobile communications，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、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、第五代(5th generation，5G)系统或未来演进的通信系统，例如第六代(6th generation，6G)系统，车到其它设备(vehicle-to-X，V2X)，其中V2X可以包括车到互联网(vehicle to network，V2N)、车到车(vehicle to vehicle，V2V)、车到基础设施(vehicle to infrastructure，V2I)、车到行人(vehicle to pedestrian，V2P)等、车间通信长期演进技术(long term evolution-vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(Internet of things，IoT)、机器间通信长期演进技术(long term evolution-machine，LTE-M)，机器到机器(machine to machine，M2M)，设备到设备(device to device，D2D)等。
上述通信系统可以基于网络中的下行链路(downlink，DL)通信和上行链路(uplink，UL)通信，不同于该DL通信和UL通信，SL通信可以支持终端设备之间的直接通信，即用户数据直接在终端设备(如接收终端设备(receiving UE，Rx UE))和终端设备(如 发送终端设备(transmitting UE，Tx UE))之间传输，可以避免蜂窝通信中用户数据经过网络中转传输，从而可以降低传输时延并且缓解网络负载。
其中，SL包括两种资源分配模式：一种是网络控制模式，即SL通信资源可以由基站调度；另一种是分布式模式，即终端设备可以从预配置的SL资源池中自发选择SL通信资源。对于在蜂窝覆盖范围内的终端设备，可以采取网络控制模式和/或分布式模式；对于在蜂窝覆盖范围外的终端设备，可以采取分布式模式。
目前，多个侧行链路设备以组(Group)为单位运行的机制能够降低时延、提高资源分配效率以及减少不同SL传输的干扰。其中，在以Group为单位运行的机制中，组间的资源需要通过组头(group header，GH)来为整个Group竞争或协商得到，而由于GH所处的位置不同，会导致竞争得到的资源结果相差较大。在GH分配组内SL传输资源时有些资源对该Group的组内成员(group member，GM)来说并不一定适合，可能会存在GH分配的资源存在组间干扰的问题。与此同时，如果SL传输中以周期性业务传输为主，这种干扰的存在则会对通信性能产生很大影响。例如，在图2所示的场景中，Group A距离Group B较远，Group A GH可能认为Group B对Group A的干扰很小，因此可能为组内的SL传输分配与Group B中的SL传输重叠的资源，而Group A中的GM1和GM2与Group B距离很近，当GM 1和GM 2进行SL通信时，如果使用了Group A GH分配的与Group B的资源重叠的资源，可能会产生严重的组间干扰，导致边缘UE性能差。
另一方面，在基于资源感知的分布式资源分配过程，Tx UE通过资源感知过程来判断其他UE预留的资源，并进行干扰规避。该Tx UE需要持续接收数据，当资源选择过程被触发时，该Tx UE需要在资源感知窗(sensing window)内盲检物理侧行控制信道(physical sidelink control channel，PSCCH)以获得资源感知结果，并根据资源感知结果来对于未来一段时间，即资源选择窗(selection window)内的资源预留情况进行判断，排除资源选择窗内的不可用的候选资源。最终在候选资源集合中(重)选择传输资源。
但是，所有的Tx UE持续接收或盲检其他UE传输的PSCCH来进行资源感知，不利于UE节省能耗。
基于此，本申请提出了一种资源选择的方法，有助于提高通信系统的抗干扰能力，降低能耗开销。
下面将以第一终端设备(可简称为第一终端，如，终端设备102)、第二终端设备(可简称为第二终端，如，终端设备103)和第三终端设备(可简称为第三终端，如，终端设备104)的交互为例，对本申请实施例进行介绍。
图3示出了本申请资源选择方法的一例示意性流程图。
S310，第一终端设备接收来自第二终端设备的第一指示信息，第一指示信息用于指示第一终端设备与第二终端设备之间在第一资源上的侧行链路SL传输质量，第一资源为第三终端设备指示的资源。
在本申请实施例中，SL传输质量可以由信道质量指示(channel quality indication，CQI)或者参考信号接收功率(reference signal receiving power，RSRP)表示，还可以由HARQ反馈信息的种类表示，例如，肯定应答(Acknowledgement，ACK)表示SL传输质量较好或者能满足使用需求，否定应答(Negative-Acknowledgment，NACK)表示SL传输质量较差或者不能满足使用需求。
其中，第一终端设备和第三终端设备属于第一SL设备组，第三终端设备可以是第一SL设备组的GH，第一终端设备可以是第一SL设备组的GM。
S320，第一终端设备确定第一指示信息满足预设条件的次数大于或等于预设值，选择第二资源，第二资源与第一资源相异(或不同)。
其中，第一指示信息满足预设条件包括以下至少一种：第一指示信息为NACK；或者，第一指示信息为CQI，该CQI小于或等于预配置的CQI阈值；或者，第一指示信息为RSRP，该RSRP小于或等于预配置的RSRP阈值。
可选地，上述方法还包括：第一终端设备向第二终端设备发送第二指示信息，第二指示信息用于指示第二终端设备发送CQI的周期和/或资源，或者，第二指示信息用于指示第二终端设备发送RSRP的周期和/或资源。
其中，第一终端设备选择第二资源包括：第一终端设备确定第一资源感知窗和第一资源选择窗；第一终端设备根据在第一资源感知窗中的感知结果，在第一资源选择窗中确定候选资源集合，感知结果用于指示第一资源选择窗中的资源的使用和/或情况；第一终端设备从候选资源集合中确定第二资源。
可选地，上述方法还包括：第一终端设备接收来自第三终端设备的资源信息，资源信息包括第一资源选择窗中未配置给第一终端设备的资源的使用和/或预留情况；第一终端设备根据在第一资源感知窗中的感知结果，在第一资源选择窗中确定候选资源集合，包括：第一终端设备根据感知结果和资源信息，在第一资源选择窗中确定候选资源集合。
可选地，上述方法还包括：第一终端设备在第二资源上与第二终端设备进行SL传输。
可选地，上述方法还包括：第一终端设备向第三终端设备发送第三指示信息，第三指示信息用于指示第一终端设备在第二资源上与第二终端设备进行SL传输。
根据本申请的技术方案，通过设置预设条件，在链路干扰较大时，进行资源选择，有助于提高通信系统的抗干扰能力，在链路质量较好时，无需进行资源选择，有助于降低能耗开销。
图4示出了本申请资源选择方法的一例具体示例的示意性流程图。
S410，第三终端设备向第一终端设备指示第一资源，用于第一终端设备与第二终端设备进行SL传输。
其中，第一终端设备和第三终端设备属于第一SL设备组。
可选地，上述第三终端设备可以是第一SL设备的GH，其可以代表第一SL设备组的组内成员获取资源或将属于第一SL设备组的资源进行整合，并将获取的资源或者整合后的资源(重新)分配给第一SL设备组的组内成员(例如，第一终端设备)。
S420，第一终端设备在第一资源上与第二终端设备进行SL传输。
其中，第一终端设备为发送方，第二终端设备为第一终端设备的接收方。
S430，第二终端设备向第一终端设备发送第一指示信息，第一指示信息可以是HARQ反馈信息，用于指示上述SL传输质量。
其中，HARQ反馈信息包括肯定应答ACK和否定应答NACK。
S440，第一指示信息满足预设条件，即第一指示信息为NCAK信息，第一终端设备开始进行资源感知。
S450，多次重复执行S420和S430，即第一终端设备与第二终端设备在第一资源上进 行多次SL传输，第二终端设备多次向第一终端设备发送第一指示信息。
S460，第三终端设备向第一终端设备发送资源信息，该资源信息用于指示未配置给第一终端设备的资源的使用和/或预留情况。
其中，未配置给第一终端设备的资源可以包括配置给第一SL设备组内其他成员的资源，还可以包括第一SL设备组外其他终端设备的资源。
应理解，步骤S460可以与步骤S410一起执行，也可以在步骤S410之后，本申请不对其进行限定。
S470，第一终端设备确定第一指示信息满足预设条件的次数大于或等于预设值，结束资源感知，选择第二资源，第二资源与第一资源相异。
具体地，如图5所示，第一终端设备可以定义第一资源感知窗和第一资源选择窗，第一资源感知窗的起始时刻可以为第一终端设备首次确定第一指示信息满足预设条件的时刻t，第一资源感知窗的结束时刻可以为第一终端设备确定第一指示信息满足预设条件的次数大于或等于预设值的时刻n。第一资源选择窗的开始时刻位于第一资源感知窗的结束时刻之后。
在第一资源感知窗的时间内，第一终端设备对资源进行感知，包括对控制信息的译码以及RSRP的测量，得到感知结果，感知结果用于指示第一资源选择窗中的资源的使用和/或预留情况。
可选地，第一终端设备可以根据上述感知结果和资源信息，在第一资源选择窗中确定候选资源集合。
具体地，第一终端设备可以根据感知结果和资源信息获知第一SL组的其他终端设备(或者组内成员)的传输情况，对于组内其他终端设备(或者组内成员)预留的SL传输落在第一资源选择窗口中的资源，则认为该资源不可用。若发现第一终端设备在第一资源选择窗中用于SL传输的资源与其他终端设备(或者组内成员)预留的资源发生重叠(部分或完全重叠)，则通过测量RSRP值做进一步判断，如果在发生重叠的资源上测量的RSRP小于或等于预配置的RSRP阈值，则确定该资源不可用。可选地，若发现第一终端设备在第一资源选择窗中用于SL传输的资源与其他终端设备(或者组内成员)预留的资源发生重叠，也可以直接确定该资源不可用，而不需要测量RSRP值做进一步判断。由此，可以排除第一资源选择窗中不可用的资源，从而得到候选资源集合。
进一步地，第一终端设备从该候选资源集合中，选择第二资源。
应理解，第一终端设备还可以只根据感知结果或者只根据资源信息，在第一资源选择窗中确定候选资源集合，本申请不对其进行限定。
可选地，经过上述资源排除过程，统计第一资源选择窗中剩余的可用候选资源，如果剩余的候选资源数少于第一资源选择窗中资源总数的X％，那么预配置的RSRP阈值可用适当减少，以满足剩余的候选资源数大于第一资源选择窗中资源总数的X％的要求，其中X的取值根据优先级可配置为20、35、50等。
S480，第一终端设备向第三终端设备发送第三指示信息，第三指示信息用于指示第一终端设备与第二终端设备在第二资源上进行SL传输。
这样，第三终端设备可以接收第一终端设备的资源选择或预留情况，从而可以根据第一终端设备的资源选择或预留情况为第一SL设备组内的其他终端设备分配资源，或者， 将第一终端设备的资源选择或预留情况发送给第一SL设备组内的其他终端设备，便于其他终端设备进一步决策。
S490，第一终端设备与第二终端设备在第二资源上进行SL传输。
根据本申请的技术方案，通过设置预设条件，在链路干扰较大时，进行资源选择，有助于提高通信系统的抗干扰能力，在链路传输质量较好时，不需要进行资源选择，有助于降低能耗开销。
图6示出了本申请资源选择方法的另一例具体示例的示意性流程图。
在该实施例中，第二终端设备被配置了需要反馈干扰程度的资源，因此在向第一终端设备发送的第一指示信息中可以包括多种反馈传输质量或者干扰程度的信息。

第二终端设备被配置需要反馈干扰程度的资源可以包括以下三种方式：

S605，第二终端设备获取本地配置的第二指示信息，第二指示信息用于指示第二终端设备发送CQI的周期和/或资源，或者，第二指示信息用于指示第二终端设备发送RSRP的周期和/或资源。
由于第二终端设备被配置了需要反馈干扰程度的资源，因此在向第一终端设备发送的第一指示信息中可以包括上述CQI或RSRP。
S606，第二终端设备向第一终端设备发送第一指示信息，与图4中S430不同的是，该实施例中，第一指示信息可以是HARQ反馈信息，还可以是上述CQI信息或RSRP信息。
S607，第一指示信息满足预设条件，第一终端设备开始进行资源感知，
其中，第一指示信息满足预设条件，可以为：第一指示信息为NACK；或者第一指示信息为CQI，CQI小于或等于预配置的CQI阈值；或者，第一指示信息为RSRP，RSRP小于或等于预配置的RSRP阈值。
S608、S609可以与S450、S460相同，为了简洁，在此不再赘述。
S610，第一终端设备确定第一指示信息满足预设条件的次数大于或等于预设值，结束资源感知，选择第二资源，第二资源与第一资源相异。
其中，当第一指示信息为NACK信息时，预设值可以为M；当第一指示信息为CQI，CQI小于或等于预配置的CQI阈值时，预设值可以为N；当第一指示信息为RSRP，RSRP小于或等于预配置的RSRP阈值时，预设值可以为K，其中M、N、K为正整数，根据资源预留间隔或资源配置周期的不同，M、N、K可以取相同或不同的值。
例如，第一指示信息为NACK信息的次数大于或等于M次时，第一终端设备结束资源感知，选择第二资源；或者，第一指示信息为CQI，CQI小于预配置的CQI阈值的次数大于或等于N次时，第一终端设备结束资源感知，选择第二资源；或者，第一指示信息为RSRP，RSRP小于预配置的RSRP的次数大于或等于K次时，第一终端设备结束资源感知，选择第二资源。可以理解地，前述前提条件可以配置为单独使用，也可以配置为满足至少两个。
在该步骤中，第一终端设备选择第二资源的具体过程可以与步骤S470中相同，在此不再赘述。
S611、S612与图4中S480、S490相同，为了简洁，在此不再赘述。
根据本申请的技术方案，通过设置预设条件，在链路干扰较大时，进行资源选择，有助于提高通信系统的抗干扰能力，在链路传输质量较好时，不需要重新选择资源，有助于降低能耗开销。
