- ProSe For public safety services.
- the resource pool is discontinuous in the time domain, so that the UE can transmit/receive data discontinuously on the sidelink, thereby achieving the effect of power saving.
- V2X Research has been conducted on vehicle-to-vehicle communication scenarios, targeting relatively high-speed moving vehicle-to-vehicle and vehicle-to-human communication services;
- V2X since the vehicle system has continuous power supply, power efficiency is not the main issue, but the delay of data transmission is the main issue. Therefore, the system design requires the terminal equipment to transmit and receive continuously.
- FeD2D Research has been conducted on scenarios where wearable devices access the network through mobile phones. It is mainly oriented to scenarios of low mobile speed and low power access.
- NR V2X is not limited to broadcast scenarios, but further extends to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.
- NR V2X will also define two resource authorization modes: mode-1/2; that is, in mode-1, the base station allocates resources used for data communication to the terminal device, and in mode2, the terminal The device selects resources from the resource pool. Furthermore, users may be in a mixed mode, that is, they can use mode-1 to obtain resources and mode-2 to obtain resources at the same time.

- PSSCH Physical Sidelink Shared Channel
- NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but also includes Multicast communication.
- Carrier selection in LTE-V2X carrier aggregation is accomplished by the following mechanisms:
- the upper layer configures the mapping relationship between service type (service type) and carrier. That is, for a certain service, the upper layer indicates the available carriers or carrier sets to the access layer (Access Stratum, AS).
- the AS configures the set of carriers available for each logical channel and the channel busy rate (Channel Busy Ratio, CBR) measurement threshold configured for the data priority (priority) in each resource pool.
- CBR Channel Busy Ratio
- the UE measures the CBR value in the resource pool and compares it with the CBR threshold corresponding to the priority of the transmitted data. If the CBR measurement value is lower than the CBR threshold, the carrier is considered available.
- CA can aggregate multiple component carriers (CCs) together and be received or transmitted by one UE at the same time.
- CA can be divided into intra-band CA (intra-band CA) and cross-band CA (inter-band CA).
- Intra-band CA intra-band CA
- inter-band CA cross-band CA
- One of the main uses of Intra-band CA is in scenarios where the cell carrier bandwidth is greater than the UE's single carrier bandwidth capability.
- the UE can use CA to operate in a "wide carrier".
- the base station supports a 300MHz carrier, but the UE only supports a maximum carrier of 100MHz.
- the UE can use CA to achieve broadband operation greater than 100MHz.
- the aggregated carriers can be adjacent carriers or non-adjacent carriers.

- BFD Beam Failure Detection
- NBI New Beam Identification
- BFRQ Beam Failure Recovery ReQest
- the terminal measures the physical downlink control channel (PDCCH) to determine the link quality corresponding to the downlink transmission beam. If the corresponding link quality is very poor, it is considered that the downlink beam has failed.
- the terminal will also perform a beam failure on the downlink beam. A group of alternative beams are measured, and the beam that meets a certain threshold is selected as the new beam. Then the terminal notifies the network side that a beam failure has occurred through BFRQ, and reports a new beam. After the network side receives the BFRQ sent by a terminal, it knows that the terminal has failed If the beam fails, the terminal chooses to send the PDCCH on the new beam. When the terminal receives the PDCCH sent by the network side on the new beam, it is considered to have correctly received the response information from the network side. At this point, the beam failure recovery process is successfully completed.
- PDCCH physical downlink control channel

- Step 1 Selection of the target address: The side-link logical channel that has data to be sent and that the target address belongs to contains the logical channel with the highest associated priority level among the currently selectable logical channels.
- Step 2 Selection of logical channels within the selected target address; among the logical channels belonging to the selected target address and meeting the above restrictions, allocate resources to the logical channel with the highest priority.

为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
LTE D2D/车辆到其他设备(Vehicle to Everything,V2X)
设备到设备通信是基于D2D的一种SL传输技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。在3GPP定义了两种传输模式:模式A和模式B。
模式A:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。如图2所示,基站210为终端设备220和终端设备230分配授权资源(Grant),终端设备220和终端设备230基 于基站分配的Grant进行数据的发送。
模式B:终端在资源池中选取一个资源进行数据的传输。如图3所示,终端设备220和终端设备230基于从资源池中获取的资源进行数据的发送。
D2D分成了以下几个不同的阶段进行研究:临近服务(Proximity based Service,ProSe)、VX2、进一步增强终端直通技术(Further Enhancements to LTE Device to Device,FeD2D)。
ProSe:针对公共安全类的业务。
在ProSe中,通过配置资源池在时域上的位置,例如资源池在时域上非连续,达到UE在侧行链路上非连续发送/接收数据,从而达到省电的效果。
V2X:针对车车通信的场景进行了研究,面向相对高速移动的车车、车人通信的业务;
在V2X中,由于车载系统具有持续的供电,因此功率效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
FeD2D:对于可穿戴设备通过手机接入网络的场景进行了研究,其主要面向是低移动速度以及低功率接入的场景。
在FeD2D中,在预研阶段3GPP结论为基站可以通过一个中继(relay)终端去配置远端(remote)终端的非连续接收(Discontinuous Reception,DRX)参数,但是由于该课题没有进一步进入标准化阶段,如何进行DRX配置的具体细节没有结论。
NR V2X
NR V2X在LTE V2X的基础上,不局限于广播场景,而是进一步拓展到了单播和组播的场景,在这些场景下研究V2X的应用。
-类似于LTE V2X,NR V2X也会定义模式(mode)-1/2两种资源授权模式;即在mode-1下,基站为终端设备分配进行数据通信所使用的资源,在mode2下,终端设备从资源池中选取资源。更进一步,用户可能处在一个混合的模式下,即既可以使用mode-1进行资源的获取,又同时可以使用mode-2进行资源的获取。该资源获取通过侧行链路授权的方式指示,即侧行链路授权指示相应的物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)与物理侧行共享信道(Physical Sidelink Share Channel,PSSCH)资源的时频位置。
-不同于LTE V2X,除了无反馈的、终端自主发起的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)重传,NR V2X引入了基于反馈的HARQ重传,不限于单播通信,也包括组播通信。
LTE-V2X载波聚合(Carrier Aggregation,CA)
LTE-V2X载波聚合中的载波选择由以下机制完成:
上层配置业务类型(service type)到载波的映射关系,即针对某项业务,上层指示给接入层(Access Stratum,AS)可用的载波或载波集合。
其中,AS配置每一个逻辑信道可用的载波集合及每个资源池中针对数据优先级(priority)配置的信道忙率(Channel Busy Ratio,CBR)测量门限值。UE测量资源池中的CBR值并与和所传输数据优先级所对应的CBR门限值相比较,若CBR测量值低于CBR门限值则认为此载波可用。
NR Uu CA
CA可以将多个成员载波(component carrier,CC)聚合在一起,由一个UE同时接收或发送。按照聚合的载波的范围分,CA又可以分为频带内CA(intra-band CA)和跨频带CA(inter-band CA)。Intra-band CA的一个主要用途是用于小区载波带宽大于UE的单个载波带宽能力的场景,这种情况下,UE可以用CA方式来实现在“宽载波”(wide carrier)中的操作。例如基站支持300MHz一个载波,而UE只支持最大100MHz的载波,此时UE可以用CA方式实现大于100MHz的宽带操作,聚合的载波可以是相邻的载波,也可以是不相邻的载波。
当终端和网络设备通过CA进行通信时,可能会同时配置主小区(Primary Cell,Pcell)和辅小区(Secondary Cell,SCell)。针对主小区(PCell)和辅主小区(PSCell)设计有波束失败恢复机制,其主要功能模块(或称为主要步骤)包括4个:波束失败检测(Beam Failure Detection,BFD);新波束选择(New Beam Identification,NBI);波束失败恢复请求(Beam Failure Recovery ReQest,BFRQ);以及网络侧响应。
终端对物理下行控制信道((Physical downlink control channel,PDCCH)进行测量,判断下行发送波束对应的链路质量。如果对应的链路质量很差,则认为下行波束发生波束失败。终端还会对一组备选波束进行测量,从中选择满足一定门限的波束作为新波束。然后终端通过BFRQ通知网络侧发生了波束失败,并且上报新波束。网络侧收到一个终端发送的BFRQ后,知道该终端发生了波束 失败,选择从新波束上发送PDCCH,终端在新波束上收到网络侧发送的PDCCH则认为正确接收了网络侧的响应信息,至此,波束失败恢复流程成功完成。
逻辑信道优先级处理(Logical Channel Prioritization,LCP)过程
侧行链路逻辑信道优先级处理指的是当生成一个新的媒体访问控制(Media Access Control,MAC)协议数据单元(Protocol Data Unit,PDU)时,对于不同的逻辑信道进行优先级排序,确定针对不同的逻辑信道/MAC控制粒子(MAC CE,CE)传输的数据量的传输的过程。
对于NR-V2X所考虑的限制条件如下:
条件1、如果当前的资源授权为模式1的配置的资源授权,逻辑信道承载的数据允许由模式1的配置的资源授权进行承载;
条件2、根据所述逻辑信道关联的配置的资源授权列表,所述逻辑信道承载的数据允许由当前配置的资源授权进行承载。
之后,在满足条件的逻辑信道集合内部,需要进一步对最终需要承载的逻辑信道进行选择,并最终决定各个逻辑信道可承载的数据量。这里具体分为两个步骤:
步骤一,对于目标地址的选择:在具有待发送的数据,并且在该目标地址所属的侧链路逻辑信道中,包含当前可选的逻辑信道中关联的优先级等级最高的逻辑信道。
步骤二,对于所选的目标地址内部,逻辑信道的选择;在属于所选目标地址中,在满足上述限制条件的逻辑信道内,将资源分配给优先级最高的逻辑信道。
发现(Discovery)消息以广播方式发送,DCR消息以单播或广播方式发送。侧行通信过程中,不管是发送这些第一条消息,还是这些第一条消息以外的数据,都是通过一个固定的载波进行发送,且不所用的终端设备都使用这一个载波,从而限制了侧行通信所能够使用的资源。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
