技术领域Technical field
本申请属于通信技术领域，具体涉及一种同步信息发送方法、装置、UE及可读存储介质。This application belongs to the field of communication technology, and specifically relates to a synchronization information sending method, device, UE and readable storage medium.
背景技术Background technique
在侧行通信中，用户设备(User Equipment，UE)与UE之间需要进行同步才能确保数据的正常传输。In sideline communication, synchronization is required between the user equipment (User Equipment, UE) and the UE to ensure normal transmission of data.
以新空口(New Radio，NR)旁链路(Sidelink，SL)为例，为了确保UE之间的同步，UE可以首先确定同步参考(即能够提供同步信息的设备)，并根据确定的同步参考获取SL传输使用的载波的同步信息，然后可以在该载波上发送旁链路同步信号块(Sidelink Synchronization Signaling Block，S-SSB)以辅助其它UE进行同步。Taking the New Radio (NR) Sidelink (SL) as an example, in order to ensure synchronization between UEs, the UE can first determine the synchronization reference (that is, the device that can provide synchronization information), and based on the determined synchronization reference Obtain the synchronization information of the carrier used for SL transmission, and then send a sidelink synchronization signal block (S-SSB) on the carrier to assist other UEs in synchronization.
然而，由于不同载波上的子载波间隔(sub-carrier space，SCS)不同，对应的SL的时分双工(Time Division Duplexing，TDD)配置也不同，且不同载波上发送S-SSB的资源不对齐，因此在同步的过程中会增加UE搜索S-SSB的次数，从而会加剧半双工问题引起的数据收发冲突。However, due to the different sub-carrier space (SCS) on different carriers, the corresponding SL time division duplexing (TDD) configuration is also different, and the resources for sending S-SSB on different carriers are not aligned. , therefore during the synchronization process, the number of times the UE searches for S-SSB will be increased, which will aggravate the data sending and receiving conflicts caused by the half-duplex problem.

下面首先对本申请的说明书和权利要求书中涉及的一些名词或者术语进行解释说明。First, some nouns or terms involved in the description and claims of this application will be explained below.
载波聚合(Carrier Aggregation，CA)，是为了满足LTE-A下行峰速1Gbps和上行峰速500Mbps的要求，并避免较大带宽的连续频谱的稀缺的影响，而提出的将2个或更多的载波单元(Component Carrier，CC)聚合在一起以支持更大的传输带宽(最大为100MHz)的方案；其中，每个CC对应一个独立的小区，每个CC的最大带宽为20MHz。CA支持满足以下至少之一的CC之间的聚合：相同或不同带宽的CC；同一频带内，邻接或非邻接的CC；不同频带内的CC，从而可以高效地利用零碎的频谱。 Carrier Aggregation (CA) is proposed to combine two or more LTE-A to meet the requirements of LTE-A downlink peak speed 1Gbps and uplink peak speed 500Mbps, and to avoid the impact of the scarcity of continuous spectrum with larger bandwidth. A solution in which carrier units (Component Carrier, CC) are aggregated together to support a larger transmission bandwidth (up to 100MHz); each CC corresponds to an independent cell, and the maximum bandwidth of each CC is 20MHz. CA supports aggregation between CCs that meet at least one of the following requirements: CCs with the same or different bandwidths; adjacent or non-adjacent CCs within the same frequency band; CCs within different frequency bands, so that fragmented spectrum can be efficiently utilized.
SL，用于UE之间不通过网络侧设备直接进行数据传输。LTE SL支持的资源分配模式包括：调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式；其中，调度资源分配模式由网络侧设备控制并为每个UE分配资源，自主资源选择模式由UE自主选择资源。LTE系统从第15个发布版本开始支持SL CA，LTE SL的CA与Uu接口(即downlink与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可以在每个CC上独立进行资源感知(sensing)与资源预留。SL is used for direct data transmission between UEs without using network-side equipment. The resource allocation modes supported by LTE SL include: scheduled resource allocation (Scheduled resource allocation) mode and autonomous resource selection (autonomous resource selection) mode; among them, the scheduled resource allocation mode is controlled by the network side device and allocates resources to each UE, and autonomous resources In the selection mode, the UE independently selects resources. The LTE system supports SL CA starting from the 15th release. The CA of LTE SL is different from the Uu interface (i.e., downlink and uplink). There is no distinction between primary carrier (Primary component carrier, PCC) and secondary carrier (Secondary component carrier, SCC). , UEs in autonomous resource selection mode can independently perform resource sensing and resource reservation on each CC.
LTE SL可以适用于特定的公共安全事务(如在火灾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；其中，V2X通信包括基本安全类通信、高级(自动)驾驶、编队或传感器扩展等业务。由于LTE SL只支持广播通信，因此LTE SL主要用于基本安全类通信，而5G NR系统可用于LTE所不支持的6GHz以上工作频段，以支持更大的工作带宽，且NR系统也支持终端之间直接通信的SL接口通信，从而可以通过NR SL进行其它高级V2X业务。LTE SL can be applied to specific public safety matters (such as emergency communications in disaster sites such as fires or earthquakes), or vehicle to everything (V2X) communications, etc.; among them, V2X communications include basic safety communications, advanced (automatic ) operations such as driving, formation or sensor expansion. Since LTE SL only supports broadcast communications, LTE SL is mainly used for basic security communications, while the 5G NR system can be used in operating frequency bands above 6GHz that LTE does not support to support larger operating bandwidth, and the NR system also supports terminals. The SL interface communicates directly between NR SLs, so that other advanced V2X services can be carried out through NR SL.
同步参考是能够提供同步信息的设备，NR SL系统中支持的同步参考包括全球导航卫星系统(Global Navigation Satellite System，GNSS)、eNB、gNB、UE，及UE内部时钟。A synchronization reference is a device that can provide synchronization information. The synchronization references supported in the NR SL system include Global Navigation Satellite System (GNSS), eNB, gNB, UE, and UE internal clock.
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的同步信息发送方法、装置、UE及可读存储介质进行详细地说明。The synchronization information sending method, device, UE and readable storage medium provided by the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.
侧行通信需要考虑不同的通信场景，如在网络覆盖范围内、网络覆盖范围外、部分网络覆盖以及UE位于不同的小区。在侧行通信中，由于UE与UE之间需要进行同步才能保证数据的正常发送和接收，因此需要在各种场景中保证UE之间的同步。在蜂窝通信中，UE只需要接收网络的同步信号，即可获取与网络之间的同步以进行通信。而在侧行通信中，由于UE可以位于小区内或小区外；且进行侧行通信的两个UE可以位于相同小区或不同小区；或者一个UE位于小区内，另一个UE位于小区外；或者该两个UE都位于小区外；因此，在侧行通信中引入了多种类型的同步参考，以满足各种场景的通信需求。Side-link communication needs to consider different communication scenarios, such as within network coverage, outside network coverage, partial network coverage, and the UE is located in different cells. In sideline communications, synchronization between UEs is required to ensure normal transmission and reception of data. Therefore, synchronization between UEs needs to be ensured in various scenarios. In cellular communication, the UE only needs to receive the synchronization signal of the network to obtain synchronization with the network for communication. In side-link communication, since the UE can be located within the cell or outside the cell; and the two UEs performing side-link communication can be located in the same cell or different cells; or one UE is located within the cell and the other UE is located outside the cell; or the Both UEs are located outside the cell; therefore, multiple types of synchronization references are introduced in sideline communications to meet the communication needs of various scenarios.
目前，在蜂窝通信系统中，小区ID(Cell ID)用于识别不同的小区，Cell ID通过主同步信号和辅同步系统承载。而在侧行通信系统中，UE在进行侧行通信之前，可以先确定同步参考，且根据同步参考确定同步信息，并在确定同步信息之后，在侧行链路上发送同步信号(Sidelink Synchronization Signal，SLSS)和物理副链路广播信道(Physical SideLink Broadcast Channel，PSBCH)，以辅助其他UE进行同步。Currently, in cellular communication systems, cell ID (Cell ID) is used to identify different cells, and Cell ID is carried through the primary synchronization signal and the secondary synchronization system. In the sidelink communication system, before performing sidelink communication, the UE can first determine the synchronization reference, determine the synchronization information based on the synchronization reference, and after determining the synchronization information, send the synchronization signal (Sidelink Synchronization Signal) on the sidelink. , SLSS) and Physical SideLink Broadcast Channel (PSBCH) to assist other UEs in synchronization.
其中，SLSS又分为侧行主同步信号(S-PSS)和侧行辅同步信号(S-SSS)。SLSS可以携带侧行同步信号标识(Sidelink Synchronization Signal Identity,SLSS ID)以区分发送同步信息的UE，NR-V2X系统支持672个SLSS ID，即N_ID^SL∈{0,1,…,671}，而{0,1,…,671}可以分为两个集合，分别为小区内ID：{0,1,…,335}，以及小区外ID：{336,337,…,671}；其中，SLSS ID 0、SLSS ID 336、SLSS ID 337预留给从GNSS获取同步信息的UE，以在发送侧行同步信号时使用。PSBCH上承载主信息块-旁链路(Master Information Block-SL，MIB-SL)，MIB-SL可以包括以下信息域中的至少之一：侧行传输系统的时分复用(Time Division Duplex，TDD)配置(sl-TDD-Config)；用于指示发送S-SSB的UE是否在小区覆盖范围内，或用于指示UE是否直接从GNSS获取同步信息的覆盖范围内指示(inCoverage)；直接帧号(directFrameNumber)，即发送S-SSB所对应的直接帧号；时隙索引(slotIndex)，即发送S-SSB所对应的时隙索引；预留比特(reservedBits)。Among them, SLSS is divided into side row primary synchronization signal (S-PSS) and side row secondary synchronization signal (S-SSS). SLSS can carry Sidelink Synchronization Signal Identity (SLSS ID) to distinguish the UE sending synchronization information. The NR-V2X system supports 672 SLSS IDs, namely N_ID^SL∈{0,1,…,671}, And {0,1,…,671} can be divided into two sets, namely intra-cell ID: {0,1,…,335}, and outside-cell ID: {336,337,…,671}; among them, SLSS ID 0. SLSS ID 336 and SLSS ID 337 are reserved for UEs that obtain synchronization information from GNSS for use when sending sideline synchronization signals. The PSBCH carries the Master Information Block-SL (Master Information Block-SL, MIB-SL). The MIB-SL can include at least one of the following information fields: Time Division Duplex (TDD) of the sidelink transmission system ) configuration (sl-TDD-Config); an in-coverage indication (inCoverage) used to indicate whether the UE sending S-SSB is within the cell coverage, or whether the UE obtains synchronization information directly from GNSS; direct frame number (directFrameNumber), which is the direct frame number corresponding to sending S-SSB; slot index (slotIndex), which is the slot index corresponding to sending S-SSB; reserved bits (reservedBits).
下面对UE确定同步信息的具体方法进行详细说明。The specific method for the UE to determine synchronization information will be described in detail below.
一、确定SLSS ID及同步资源1. Determine SLSS ID and synchronization resources
(一)UE位于小区覆盖范围内(1) UE is located within the coverage of the cell
当UE位于小区覆盖范围内时，UE可以从网络侧设备获取侧行传输的配置参数。网络侧设备可以通过系统信息块信息(即SIB信息，例如System Information Block Type21)或无线资源控制(Radio Resource Control，RRC)信令配置当前小区所在的载波上的侧行传输参数，或者配置用于侧行传输的相邻载波(例如5.9GHz的ITS载波)的传输参数。网络侧设备配置相邻载波的传输参数适用于侧行传输的载波和当前载波属于不同载波的情况，例如侧行传输使用专有载波。而对于每个载波，网络侧设备可以为该载波配置多套同步参数配置，在每套同步参数配置中，包括同步参考类型、同步信号ID、同步资源等相关的参数。从而UE在侧行链路上传输侧行同步信息时，可以从网络侧设备配置的多套同步参数中选取一套确定相应的同步参数进行传输。When the UE is located within the cell coverage, the UE can obtain the sidelink transmission configuration parameters from the network side device. The network side device can configure the sidelink transmission parameters on the carrier where the current cell is located through system information block information (ie, SIB information, such as System Information Block Type21) or Radio Resource Control (RRC) signaling, or configure it for Transmission parameters of adjacent carriers for sidelink transmission (such as 5.9GHz ITS carrier). The network-side device configures the transmission parameters of adjacent carriers when the carrier for side-link transmission and the current carrier belong to different carriers. For example, a dedicated carrier is used for side-link transmission. For each carrier, the network side device can configure multiple sets of synchronization parameter configurations for the carrier. Each set of synchronization parameter configurations includes synchronization reference type, synchronization signal ID, synchronization resources and other related parameters. Therefore, when the UE transmits sidelink synchronization information on the sidelink, it can select one set from multiple sets of synchronization parameters configured by the network side device to determine the corresponding synchronization parameters for transmission.

二、确定MIB-SL的信息域2. Determine the information domain of MIB-SL
情况1：在用于NR侧链通信的载波的覆盖范围内；Case 1: Within the coverage of the carrier used for NR side chain communication;
incoverage：true；coverage: true;
sl-TDD-Config：如果收到的SIB1配置了tdd-UL-DL-ConfigurationCommon，将sl-TDD-Config设置为与tdd-UL-DL-ConfigurationCommon含义相同的值；否则设置sl-TDD-Config所有比特为全“1”；sl-TDD-Config: If the received SIB1 is configured with tdd-UL-DL-ConfigurationCommon, set sl-TDD-Config to a value with the same meaning as tdd-UL-DL-ConfigurationCommon; otherwise set sl-TDD-Config to all The bits are all “1”;

reservedBits：将reservedBits设置为预配置的值。reservedBits: Set reservedBits to a preconfigured value.
然而，由于R18NR SL引入了载波聚合技术，为了实现载波对齐，UE可以确定同步载波的同步参考为其他CA传输载波的同步参考，并在多个载波上发送S-SSB，因此UE需要确定各个载波上的SLSS和PSBCH，包括确定同步资源、SLSS ID以及MIB-SL中的内容，以使不同载波上发送S-SSB的资源对齐。但由于NR SL支持多个SCS，及多个S-SSB的repetition个数，并且SL的TDD配置与载波的SCS相关联，因此不同载波上的SCS不同，对应的SL的TDD配置不同，且不同载波上发送S-SSB的资源不对齐。而按照上述方法，UE只能确定一个载波上的SLSS和PSBCH，并在对应载波上发送S-SSB，即使按照上述方法分别确定每个载波上的SLSS和PSBCH，并在对应载波上发送S-SSB，也会使得不同载波上发送S-SSB的资源不对齐，从而UE需要增加搜索S-SSB的次数，如此一方面会增加UE的功耗，另一方面会加剧半双工问题引起的数据收发冲突。However, since R18NR SL introduces carrier aggregation technology, in order to achieve carrier alignment, the UE can determine the synchronization reference of the synchronization carrier as the synchronization reference of other CA transmission carriers and send S-SSB on multiple carriers, so the UE needs to determine each carrier SLSS and PSBCH on different carriers, including determining the synchronization resources, SLSS ID and content in MIB-SL to align the resources for sending S-SSB on different carriers. However, since NR SL supports multiple SCS and the number of repetitions of multiple S-SSBs, and the TDD configuration of SL is associated with the SCS of the carrier, the SCS on different carriers is different, and the corresponding TDD configuration of the SL is different and different. The resources for sending S-SSB on the carrier are not aligned. According to the above method, the UE can only determine SLSS and PSBCH on one carrier and send S-SSB on the corresponding carrier. Even if according to the above method, it determines SLSS and PSBCH on each carrier separately and sends S-SSB on the corresponding carrier. SSB will also cause the resources for sending S-SSB on different carriers to be misaligned, so the UE needs to increase the number of times it searches for S-SSB. This will increase the power consumption of the UE on the one hand, and aggravate the data loss caused by the half-duplex problem on the other. Transceiver conflict.
为了解决上述问题，在本申请实施例提供的同步信息发送方法中，由于第一UE可以确定至少两个载波中的每个载波上的第一参数，且第一参数可以用于第一UE在对应的载波上进行第一传输，因此使得在不同载波上的发送S-SSB的内容及同步资源对齐，从而可以减少UE搜索的次数，如此可以节约UE的功耗，并减少半双工问题引起的数据收发冲突。In order to solve the above problem, in the synchronization information sending method provided by the embodiment of the present application, since the first UE can determine the first parameter on each carrier of at least two carriers, and the first parameter can be used by the first UE in The first transmission is performed on the corresponding carrier, so that the content and synchronization resources of the S-SSB sent on different carriers are aligned, thereby reducing the number of UE searches, which can save the power consumption of the UE and reduce the half-duplex problem caused by Data sending and receiving conflicts.

可以理解，若一个UE(以下称为第二UE)从第一UE接收到S-SSB，则第二UE可以根据该S-SSB，确定出对应的传输资源上的第一参数，从而可以方便第二UE进行同步。It can be understood that if a UE (hereinafter referred to as the second UE) receives the S-SSB from the first UE, the second UE can determine the first parameter on the corresponding transmission resource based on the S-SSB, which can facilitate The second UE performs synchronization.
