Technical field

本公开实施例涉及无线通信技术领域，尤其涉及一种副链路传输资源的选择方法、配置方法及设备。Embodiments of the present disclosure relate to the field of wireless communication technologies, and in particular, to a method, a configuration method, and a device for selecting a secondary link transmission resource.

Background technique

长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持副链路(sidelink，或译为侧链路，边链路等)，用于终端用户设备(User Equipment，UE，简称为终端)之间不通过网络侧设备进行直接数据传输。Long term evolution (LTE) systems have supported side links (sidelink, or side links, side links, etc.) since the twelfth release, and are used for end user equipment (User Equipment, UE, referred to as (Terminals) do not directly transmit data through the network-side device.

UE通过物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)发送副链路控制信息(Sidelink Control Information，SCI)，调度物理副链路共享信道(Physical Sidelink Shared Channel，PSSCH)的传输以发送数据。该传输是以广播形式进行的，接收端并不向发送端反馈接收是否成功。The UE sends side link control information (SCI) through the physical side link control channel (PSCCH), and schedules transmission of the physical side link shared channel (PSSCH) to send data. . The transmission is performed in a broadcast form, and the receiving end does not feedback to the transmitting end whether the reception was successful.

LTE sidelink设计支持两种资源分配模式，分别是调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式。前者由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。The LTE sidelink design supports two resource allocation modes, namely, a scheduled resource allocation mode and an autonomous resource selection mode. The former is controlled by network-side equipment and allocates resources to each UE, while the latter is the UE's own choice of resources.

从第15个发布版本开始，LTE支持sidelink载波聚合(Carrier Aggregation，CA)。LTE sidelink的CA与Uu接口(即下行(downlink)与上行(uplink))不同，没有主载波(Primary component carrier，PCC)与辅载波(Secondary component carrier，SCC)之分。自主资源选择模式的UE在每个成员载波(CC)上独立进行资源感知(sensing)与资源预留。Starting from the 15th release, LTE supports sidelink carrier aggregation (CA). The CA and Uu interfaces (ie, downlink and uplink) of LTE sidelink are different. There is no distinction between primary carrier (PCC) and secondary component carrier (SCC). The UE in the autonomous resource selection mode independently performs resource sensing and resource reservation on each component carrier (CC).

LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他高级V2X业务将通过NR sidelink支持。The design of LTE sidelink is suitable for specific public safety affairs (such as emergency communication in disaster places such as fire or earthquake), or vehicle-to-everything (V2X) communication. Vehicle-to-vehicle communication includes various services, such as basic safety communication, advanced (automatic) driving, formation, sensor expansion, and so on. Since LTE sidelink only supports broadcast communication, it is mainly used for basic security communications. Other advanced V2X services will be supported by NR sidelink.

5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，但目前版本的NR系统只支持基站与终端间的接口，尚不支持终端之间直接通信的Sidelink接口。The 5G NR system can be used in the operating frequency bands above 6GHz, which is not supported by LTE, and supports a larger working bandwidth. However, the current version of the NR system only supports the interface between the base station and the terminal, and does not yet support the sidelink interface for direct communication between the terminals.

在NR的V2X设计中，如何选择副链路的传输资源以传输数据还没有明确的说明。In the V2X design of NR, how to select the transmission resources of the secondary link to transmit data has not been clearly explained.

请参考图2，图2为本公开实施例的副链路传输资源的选择方法的流程示意图，该副链路传输资源的选择方法应用于终端，包括：Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for selecting a secondary link transmission resource according to an embodiment of the present disclosure. The method for selecting a secondary link transmission resource applied to a terminal includes:

步骤21：根据副链路的相关配置信息，进行所述副链路的传输资源的选择、重选或重配，所述传输资源为：载波、部分带宽(BWP)或资源池；Step 21: Select, reselect or reconfigure transmission resources of the secondary link according to the related configuration information of the secondary link, where the transmission resources are: a carrier, a partial bandwidth (BWP), or a resource pool;

每一所述传输资源对应的服务质量(QoS)需求的配置信息；Configuration information of quality of service (QoS) requirements corresponding to each of the transmission resources;

触发重选或重配所述传输资源的信道繁忙比率(channel busy ratio，CBR) 门限的配置信息；Configuration information of a channel busy ratio (CBR) threshold that triggers reselection or reconfiguration of the transmission resource;

CBR是V2X中用于拥塞控制的一个参数。每次传输UE都会测量CBR的值，对于不同的传输资源，UE可以根据测量CBR的结果，来动态调整自己的传输参数，如最大传输功率，重传次数，调制和编码机制(Modulation and Coding Scheme，MCS)等等。CBR is a parameter used in V2X for congestion control. The UE will measure the CBR value for each transmission. For different transmission resources, the UE can dynamically adjust its own transmission parameters, such as the maximum transmission power, the number of retransmissions, the modulation and coding scheme (Modulation and Coding Scheme), based on the results of the CBR measurement. , MCS) and so on.

本公开实施例中，在进行副链路的传输资源的选择时，考虑传输资源对应的QoS需求和/或CBR信息，从而提高通信效率。In the embodiment of the present disclosure, when selecting transmission resources of a secondary link, QoS requirements and / or CBR information corresponding to the transmission resources are considered, thereby improving communication efficiency.

所谓传输资源的重选，是指当前已经选择并采用了一传输资源进行传输的情况下，重新选择另一传输资源进行传输。The so-called reselection of transmission resources refers to re-selecting another transmission resource for transmission when one transmission resource is currently selected and used for transmission.

所谓传输资源的重配，是指当前已经选择并采用了一传输资源进行传输的情况下，向网络侧设备发送请求，请求网络侧设备为终端重新分配传输资源。The so-called transmission resource reconfiguration refers to a case where a transmission resource is currently selected and used for transmission, and a request is sent to a network-side device to request the network-side device to reallocate the transmission resource to the terminal.

下面对副链路的资源池(pool)的含义进行说明：The meaning of the resource pool of the secondary link is described below:

目前V2X传输的时候有“资源池”的概念，资源池由网络侧发送或预配置，资源池中包含传输所用的资源和很多传输相关的参数，例如包括资源池第一个子帧的偏移值、资源池对应的位图(bitmap)、是否会在相邻资源块(RB)传输PSCCH和PSSCH、子信道的数量和每个子信道的大小以及子信道对应的最低RB索引值、PSCCH资源池对应的最低RB索引值、信道繁忙比率(CBR)测量的接收信号强度(Receive Signal Strength Indicator，S-RSSI)门限、区域标识等等。At present, V2X transmission has the concept of "resource pool". The resource pool is sent or pre-configured by the network side. The resource pool contains the resources used for transmission and many transmission-related parameters, such as the offset of the first subframe of the resource pool. Value, bitmap corresponding to the resource pool, whether PSCCH and PSSCH will be transmitted in adjacent resource blocks (RB), the number of subchannels and the size of each subchannel, and the minimum RB index value corresponding to the subchannel, PSCCH resource pool Corresponding minimum RB index value, Received Signal Strength (S-RSSI) threshold, area identifier, etc. measured by Channel Busy Ratio (CBR).

目前网络侧除了给UE配置普通的传输资源池，还可能会配置异常资源池(exceptional pool)，异常资源池用于一些特殊的情况，如在切换过程中，或发生无线链路失败(radio link failure，RLF)，或是从空闲态(IDLE态)向连接态(CONNECTED态)转换的过程中，等等。At present, in addition to configuring a common transmission resource pool for the UE, an abnormal resource pool may also be configured on the network side. The abnormal resource pool is used in some special situations, such as during a handover process or a radio link failure (radio link failure (RLF), or during the transition from the idle state (IDLE state) to the connected state (CONNECTED state), and so on.

本公开实施例中，所述传输资源对应的QoS需求的配置信息包括以下至少之一：In the embodiment of the present disclosure, the configuration information of the QoS requirements corresponding to the transmission resources includes at least one of the following:

最大传输距离(Maximum required communication range)；Maximum transmission distance (Maximum required communication range);

最大传输距离的索引；The index of the maximum transmission distance;

最小传输距离(Minimum required communication range)；Minimum transmission distance (Minimum required communication range);

最小传输距离的索引；The index of the minimum transmission distance;

传输距离范围；Transmission distance range;

传输距离范围的索引；The index of the transmission distance range;

数据包大小(Payload)；Data packet size (Payload);

数据包大小的索引；Index of packet size;

数据速率(Data rate)；Data rate (Data rate);

在本公开的一些实施例中，所述副链路的相关配置信息包括：每一所述传输资源对应的QoS需求的配置信息；此时，所述根据副链路的相关配置信息，进行所述副链路的传输资源的选择、重选或重配包括：In some embodiments of the present disclosure, the related configuration information of the secondary link includes: configuration information of QoS requirements corresponding to each of the transmission resources; at this time, the performing The selection, reselection, or reconfiguration of transmission resources of the secondary link includes:

步骤211：根据V2X服务的数据包的QoS需求和每一所述传输资源对应的QoS需求的配置信息，从所述副链路的传输资源中，选择与所述数据包的QoS需求匹配的目标传输资源。Step 211: Select a target that matches the QoS requirement of the data packet from the transmission resources of the secondary link according to the QoS requirement of the data packet of the V2X service and the configuration information of the QoS requirement corresponding to each of the transmission resources. Transmission resources.

或者or

步骤211’：根据V2X服务的承载的QoS需求和每一所述传输资源对应的QoS需求的配置信息，从所述副链路的传输资源中，选择与所述承载的QoS需求匹配的目标传输资源。Step 211 ': According to the QoS requirements of the bearer of the V2X service and the configuration information of the QoS requirements corresponding to each of the transmission resources, from the transmission resources of the secondary link, select a target transmission that matches the QoS requirements of the bearer. Resources.

不同的V2X服务有不同的QoS需求，包括：传输速率、时延和/或最小传输距离等，本公开实施例中，在传输资源的选择时，考虑到不同V2X服务的QoS需求，让具有不同需求的V2X服务选择不同的传输资源，提高通信效率。Different V2X services have different QoS requirements, including: transmission rate, delay, and / or minimum transmission distance. In the embodiments of the present disclosure, when selecting transmission resources, the QoS requirements of different V2X services are taken into account, so that The required V2X service selects different transmission resources to improve communication efficiency.

LTE系统的副链路传输是基于广播进行的，终端在物理层并没有建立点对点连接，也不存在反馈机制。接收端并不向发送端反馈接收是否成功，也不能进行信道测量并反馈测量结果。NR系统的V2X研究目前刚刚开始，目前倾向于在NR系统中，支持多种传输方式，包括单播、组播和广播。单播顾名思义就是one to one的传输，组播为one to many的传输。广播也是one to many的传输，但是广播并没有UE属于同一个组的概念。因而，本公开实施例中，V2X服务的数据传输可以是广播方式进行，对应于步骤211中发送数据包的方式，也可以是通过点对点方式进行，即建立承载的方式。The secondary link transmission of the LTE system is based on broadcasting. The terminal does not establish a point-to-point connection at the physical layer, and there is no feedback mechanism. The receiving end does not feedback to the transmitting end whether the reception was successful, nor can it perform channel measurement and feedback the measurement result. V2X research on NR systems has just begun, and currently tends to support multiple transmission methods in NR systems, including unicast, multicast, and broadcast. Unicast, as its name implies, is one-to-one transmission, and multicast is one-to-many transmission. Broadcasting is also one-to-many transmission, but broadcasting does not have the concept that UEs belong to the same group. Therefore, in the embodiment of the present disclosure, the data transmission of the V2X service may be performed in a broadcast manner, corresponding to the manner of sending the data packet in step 211, or may be performed in a point-to-point manner, that is, a manner of establishing a bearer.

在本公开的一些实施例中，所述传输资源对应的QoS需求的配置信息包括：最小传输距离和/或最小传输距离的索引；其中，所述目标传输资源对应的最小传输距离小于或等于所述V2X服务的数据包或承载的最小传输距离，或，所述目标传输资源对应的最小传输距离的索引与所述V2X服务的数据包或承载的最小传输距离的索引相同或具有对应关系；所述目标传输资源对应的最小传输距离的索引与所述V2X服务的数据包或承载的最小传输距离的索引具有对应关系时，所述目标传输资源对应的最小传输距离的索引对应的最小传输距离，小于或等于所述V2X服务的数据包或承载的最小传输距离的索引对应的最小传输距离。例如，所述V2X服务的数据包或承载的最小传输距离的索引为01，对应的最小传输距离为20公里，与索引01具有对应关系的索引包括：索引10和索引11，其中，索引10对应的最小传输距离为10公里，索引11对应的最小传输距离为5公里。In some embodiments of the present disclosure, the configuration information of the QoS requirements corresponding to the transmission resources includes: a minimum transmission distance and / or an index of the minimum transmission distance; wherein the minimum transmission distance corresponding to the target transmission resource is less than or equal to The minimum transmission distance of the data packet or bearer of the V2X service, or the index of the minimum transmission distance corresponding to the target transmission resource and the index of the minimum transmission distance of the data packet or bearer of the V2X service; When the index of the minimum transmission distance corresponding to the target transmission resource and the index of the minimum transmission distance of the data packet or bearer of the V2X service have a corresponding relationship, the minimum transmission distance corresponding to the index of the minimum transmission distance corresponding to the target transmission resource, The minimum transmission distance corresponding to the index of the minimum transmission distance of the data packet or bearer of the V2X service. For example, the index of the minimum transmission distance of the data packet or bearer of the V2X service is 01, and the corresponding minimum transmission distance is 20 kilometers.

步骤2.1：如果V2X服务的数据包每个都有对应的QoS需求，那么UE根据V2X服务的数据包的QoS需求，进行副链路的传输资源的选择。Step 2.1: If each of the data packets of the V2X service has a corresponding QoS requirement, the UE selects transmission resources of the secondary link according to the QoS requirements of the data packets of the V2X service.
