Definitions
- the present disclosure relates to the field of communication technology, and in particular, to a sequence generation method, signal reception method and device, and terminal.
- the terminal In Long Term Evolution (LTE) vehicle networking (V2X), according to whether the terminal (User Equipment, UE) is within the coverage of the base station, the terminal can be divided into:
- the network indicates the sidelink synchronization signal sequence that the terminal needs to transmit in the system information block (System Information Block, SIB) or radio resource control (Radio Resource Control, RRC), and the terminal uses the network indication
- SIB System Information Block
- RRC Radio Resource Control
- the sidelink resource transmits the sidelink synchronization signal sequence, and the sidelink resource indicated by the network is used for sidelink communication.
- Out-of-coverage terminal The terminal selects the sidelink transmission resource from the resource pool pre-configured by the manufacturer.
- the terminal can select the sidelink synchronization signal sequence by itself, or derive the sidelink synchronization signal sequence that should be used according to its synchronization source, and perform sidelink Communication.
- the terminal can be divided into:
- 1.mode3 terminal This type of user is used by the base station to schedule the resources it uses to communicate on the sidelink.
- 2.mode4 terminal This type of user selects the resources used for communication on the sidelink according to the sensing (sensing) results and energy measurement.
- terminals can also be divided into terminals within coverage and terminals beyond coverage, or terminals can be divided into mode1 terminals and mode2 terminals.
- Mode1 terminal is similar to LTE V2X mode3 terminal, the base station schedules its transmission on the sidelink, mode2 terminal is similar to LTE V2X mode4 terminal, and there is no base station scheduling.
- the random sequence generation and scrambling of LTE are based on Physical Cell Identifier (PCI). Due to the different PCIs of adjacent cells, the generated sequences are also different. Therefore, the random sequences of different cells can be different, so as to achieve random inter-cell interference. To improve decoding performance.
- PCI Physical Cell Identifier
- NR synchronization signal block Sychronization Signal Block
- two layers of scrambling are performed for the physical broadcast channel (PBCH). Both layers of scrambling are initialized based on PCI, and a scrambling sequence of length L is generated.

- PSBCH Physical Sidelink Broadcast Control Channel
- other sidelink terminals may receive synchronization signal blocks of multiple sending ends on the same sidelink resource at the same time.
- PSBCH Physical Sidelink Broadcast Control Channel
- the result measured on this resource is actually the superposition of multiple synchronization signal blocks at the sending end, which is inaccurate, and beam-related operations cannot be performed in a multi-beam scenario.
- the scrambling code sequence generated when different sending ends using the same synchronization signal sequence send the same index S-SSB on the same resource may be completely the same, and random interference cannot be achieved At this time, even if the sending end can indicate its own identity through the PSBCH carrying the terminal identifier, the receiving end may fail due to interference during decoding.
- the scheduling control information (sidelink control information, SCI) of different sidelink terminals is initialized in exactly the same way, so all sending ends use the same scrambling code sequence. Due to the high terminal density in NR sidelink, the probability of SA resource conflicts at different senders rises. Once SA resource conflicts occur, the use of LTE SCI scrambling will cause serious interference problems.

本公开涉及通信技术领域,特别是指一种序列生成方法、信号接收方法及装置、终端。
在长期演进(Long Term Evolution,LTE)车联网(vehicle to everything,V2X)中,根据终端(User Equipment,UE)是否在基站覆盖范围内,可以将终端分为:
1.覆盖范围内终端:网络在系统信息块(System Information Block,SIB)或者无线资源控制(Radio Resource Control,RRC)中指示终端需要传输的旁链路(sidelink)同步信号序列,终端使用网络指示的sidelink资源传输sidelink同步信号序列,以及使用网络指示的sidelink资源进行sidelink通信(communication)。
2.覆盖范围外终端:终端从厂商预配置的资源池中选择sidelink传输资源,终端可以自行选择sidelink同步信号序列,或者根据自己的同步源来推导出应该使用的sidelink同步信号序列,以及进行sidelink通信。
根据终端进行资源选择的模式可以将终端分为:
1.mode3终端:这类用户由基站进行调度其在sidelink上进行通信时使用的资源。
2.mode4终端:这类用户根据感测(sensing)结果和能量测量,自行选择在sidelink上进行通信时使用的资源。

NR同步信号块(Sychronization Signal Block,SSB)中针对物理广播信道(physical broadcast channel,PBCH)进行了两层加扰,两层加扰都基于PCI进行初始化,并生成长度为L的加扰序列。第一层加扰中,基于系统帧号(System Frame Number,SFN)第2位和第3位确定用于加扰的序列部分,例如该两位=00时,选择该长度为L的序列的前四分之一。第二层加扰中,基于SSB index低2位或低3位确定用于加扰的序列部分,例如基于SSB index低2位确定用于加扰的序列部分,该两位=00时,选择该长度为L的序列的前四分之一。
相关技术存在以下问题:
不同的sidelink终端可能使用相同的sidelink资源来传输sidelink同步信号块,并且使用相同的同步信号序列,但是其sidelink同步信号块携带的其他内容例如物理旁链路广播控制信道(Physical sidelink broadcast Control Channel,PSBCH)的部分内容可能是不同的,此时其他sidelink终端可能在同一块sidelink资源上同时收到多个发送端的同步信号块,然而无法通过检测同步信号序列直接区分出来自不同发送端的同步信号块,并且也无法通过解码出不同的PSBCH而确定其发送端。另一方面,在该资源上测量出的结果实际上是多个发送端的同步信号块的叠加,并不准确,在多波束的场景下也无法进行波束相关的操作。
上述场景中如果PSBCH沿用R15 NR SSB的扰码生成公式,使用相同同步信号序列的不同发送端在相同资源上发送相同index的S-SSB时生成扰码序列可能是完全相同的,无法实现干扰随机化,此时即使发送端能通过PSBCH携带终端标识来指示自己的身份,接收端在解码时也可能因为干扰问题失败。
LTE中不同sidelink终端的调度控制信息(sidelink control information,SCI)初始化方式完全一样,因此所有发送端都用相同的扰码序列。由于NR sidelink中终端密度很高,不同发送端的SA资源冲突的概率上升,一旦出现SA资源冲突,沿用LTE SCI的加扰方式会导致干扰严重的问题。

为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
本实施例的技术方案不仅仅适用于sidelink通信中,还适用于其他的通信系统中。其中,旁链路也可以称为边链路、直连链路,都属于同一概念,对应英文中的sidelink。
旁链路(sidelink)终端可以发送调度分配信令(Scheduling Assignment,SA),该信令用于承载sidelink数据的SCI,SCI在物理旁链路控制信道(Physical sidelink Control Channel,PSCCH)上传输,SCI用于调度sidelink上数据,数据在物理旁链路共享信道(Physical sidelink Shared Channel,PSSCH)上传输。针对发送端发送的sidelink数据,接收端可能会反馈ACK/NACK,接收端也可能针对检测sidelink信道反馈信道状态信息(Channel State Information,CSI)给发送端,这类反馈信息为旁链路反馈控制信息(sidelink feedback control information,SFCI),SFCI在物理旁链路反馈控制信道(Physical sidelink feedback Control Channel,PSFCH)上传输。
在LTE V2X中,sidelink终端在sidelink上广播同步序列主SIDelink同步信号(primary sidelink synchronization signal,PSSS)和辅SIDelink 同步信号(secondary sidelink synchronization signal,SSSS),以及物理旁链路广播信道(physical sidelink broadcast channel,PSBCH),其中PSSS,SSSS用于帮助接收终端获取该发送终端的子帧级别的定时信息,Sidelink中S-PSS S-SSS和PSBCH可以组成sidelink同步信号块(S-SSB)的形式进行传输(包括发送和接收)。
在不同的通信系统中本公开所涉及的信号的名称和缩写会出现对应的变化,在缩写变化的时候本公开的技术方案依然是适用的。

下面结合具体的实施例对本公开的技术方案进行进一步介绍:
实施例1:
例如辅助信息中包含传输模式,不同的传输模式:广播,单播,多播,其中的至少两个传输模式对应不同的初始化状态;更具体地,广播时初始化值cinit=00,单播时cinit=01,多播cinit=10.或者,不同的传输模式:广播,单播,多播中的至少两个对应不同的序列生成公式;更具体地,广播时使用序列公式1生成序列,单播时使用序列公式2生成序列,多播使用序列公式3生成序列;或者,不同的传输模式:广播,单播,多播中的至少两个对应不同的候选序列;更具体地,广播时可用序列为序列1-4,单播时可用序列为序列5-8,多播时可用序列为序列9-12。或者,不同的传输模式:广播,单播,多播中的至少两个对应序列中的不同部分;更具体地,广播时对应序列的0~M-1比特,单播时对应序列的M~2M-1比特,多播时对应序列的2M~3M-1比特。或不同的传输模式:广播,单播,多播中的至少两个对应序列的不同循环移位;更具体地,广播时对应序列的循环移位α,单播时对应序列的的循环移位β,多播时对应序列的的循环移位γ。

实施例2:
例如基于标识信息确定序列生成的初始化状态,如果对应的参考信号中也携带标识信息,该inf_id和参考信号中携带的标识信息至少部分重叠;更优 地,是全集或者子集或者超集关系,即包含关系。
例如,对于S-SSB,S-SSB中的RS携带UE ID信息,PSBCH的扰码也基于UE ID信息确定初始化值Cinit,则对于PSBCH的扰码,用于确定Cinit的UE ID信息为S-SSB中的RS携带的UE ID信息的全集(即完全相同)或者子集。
又例如基于扰码所属信号的内容信息Payload
mapping确定序列生成的初始化状态,如果对应的参考信号中也携带扰码所属信号的内容信息,该Payload

例如,对于S-SSB,S-SSB中的RS携带了至少部分PSBCH payload或者至少PSBCH payload部分通过函数转换得到的映射值,即RS携带S-SSB的内容相关信息,PSBCH的扰码也基于PSBCH payload相关信息Payload
mapping确定初始化值Cinit,则对于PSBCH的扰码,用于确定Cinit的Payload
mapping为S-SSB中的RS携带的PSBCH payload信息的全部或者子集。
上述针对S-SSB,对于其他信号或者信道,例如PSSCH PSCCH PSFCH,类似的方案设计也适用。此时参考信号分别指的是PSSCH PSCCH PSFCH的参考信号,而扰码所属信号分别指的是PSSCH PSCCH PSFCH。

假设标识信息inf_id中包含第一信息和第二信息,一种是实施例是:
基于第一信息确定序列生成的初始化状态:Cinit=第一信息。
如果进行一层加扰:可选地,可以基于定时信息例如帧号信息的比特位数和/或标识信息的比特位数确定需要生成的序列及其长度,并根据携带的帧号信息的取值和/或标识信息的取值确定用于当前信号加扰的扰码序列。
如果进行两层加扰:一层加扰基于定时信息例如帧号信息的比特位数和/或第一信息的比特位数确定需要生成的序列及其长度,并根据定时信息和/或第一信息的取值确定用于当前信号加扰的扰码序列。另一层加扰基于第二信息的位数确定需要生成的序列及其长度,并根据携带的第二信息取值确定用于当前信号加扰的扰码序列。
一种更具体的实施方式是:第一信息是UE标识
第二信息是S-SSB index,并基于第一信息确定序列生成的初始化状态:
不排除第一信息,第二信息为其他标识信息的实现,例如第一信息或第二信息为同步源 标识等。
假设基于PSBCH payload信息Payload
mapping确定序列生成的初始化状态c
init=Payload
mapping,假设标识信息inf_id中包含第三信息。
如果进行一层加扰:可选地,可以基于定时信息例如帧号信息的比特位数和/或PSBCH payload信息Payload
mapping的比特位数确定需要生成的序列及其长度,并根据携带的帧号信息的取值和/或PSBCH payload信息Payload
mapping的取值确定用于当前信号加扰的扰码序列。
如果进行两层加扰:一层加扰基于定时信息例如帧号信息的位数和/或Payload

mapping的取值确定用于当前信号加扰的扰码序列。另一层加扰基于第三信息的位数确定需要生成的序列及其长度,并根据携带的第三信息取值确定用于当前信号加扰的扰码序列。
一种更具体的实施方式是:第三信息S-SSB index。不排除第三信息为其他标识信息的实现。
