本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单 元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。

请参见图1，图1示出本发明实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本发明实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构 成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端11到网络侧设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络侧设备12到终端11)的下行链路，用于承载终端11到其他终端11之间传输的旁链路(Sidelink，SL，或译为副链路，侧链路，边链路等)。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
Sidelink中基站可以配置或者厂商可以预配置2个或者3个用于传输(收或者发)旁链路同步信号块(Sidelink-Synchronization Signal Block，S-SSB)的同步资源(Sync Resource)，如图2所示，每个Sync Resource中包含1-64个S-SSB传输所需的资源。用户会从中选一个Sync Resource用于发送S-SSB，并在其余的Sync Resource上收S-SSB。
Sidelink用户在进行Sidelink传输前需要先确定同步源(Synchronization reference source，也可能称为同步参考，Synchronization reference，也可能称为定时参考，timing reference)，其传输会基于获得的定时来进行，用户的同步源可以是基站、全球导航卫星系统(Global Navigation Satellite System，GNSS)、自身本地时钟产生的定时或者其他用户提供的定时。具体来说，一个Sidelink用户可以通过发送S-SSB来将自己的定时信息发送出去，其他用户可以通过接收该S-SSB并获取定时信息来将该Sidelink用户当做自己的同步源。
通常用户会在一定范围内搜索S-SSB或者GNSS或者基站，选择质量最好的或者优先级最高的一个作为同步源。
不同的Sync Resource通常时域位置也不同，例如假设在载波1上有两个Sync Resource可以用于传输一个S-SSB，预配置中Sync Resource1包含一个slot，位于直接帧号1(Direct frame number，DFN)的slot1，Sync Resource2包含一个slot，位于DFN1的slot2。
相关技术中，Sidelink用户只有在解码PSBCH后才能获取接收到的S-SSB的定时信息(帧级别定时10bit+slot级别定时7bit)，并能够确定收到的S-SSB属于哪个Sync Resource，从而进一步确定自己要在哪个Sync Resource上接收S-SSB，可以用哪个Sync Resource发送S-SSB。
本发明实施例提供了一种旁链路参考信号处理方法及装置、通信设备，能够使得用户在解码PSBCH之前就能够确定部分定时信息甚至全部的定时信息，从而提前获取定时信息，降低PSBCH中定时信息的开销以及降低PSBCH解码复杂度。

至少部分旁链路定时信息。
上述实施例中，参考信号可以是信道状态信息(Channel State Information，CSI)-参考信号(reference signal，RS)、相位追踪(Phase-tracking，PT)-RS、探测参考信号(Sounding reference signal,SRS)、追踪参考信号(Tracking reference signal，TRS)和解调参考信号(Demodulation Reference Signal，DMRS)等中的至少一项。
一具体示例中，假设Sync Resource包含X个S-SSB，由于Sync Resource唯一地对应一个或者一组资源，例如当X＝1时，Sync Resource唯一地对应一个帧号和一个帧内slot，即能够确定7bit完整的slot定时信息；当X>1时，Sync Resource唯一地对应X个slot，进一步地结合S-SSB index可以确定Sync Resource内每个slot的序号。
因此，通过在RS携带Sync Resource可以帮助用户在解码PSBCH前获得至少部分定时相关信息，从而可以降低PSBCH中携带的定时信息的开销。并且对于某些情况，例如FR1的Sidelink专用频段上，可以认为所有时域资源都可以用于Sidelink，而且此时X<＝4，因此DMRS携带2bit Sync Resource序号+2bit S-SSB index即可提供完整的定时相关信息，从而用户不需要每次都解PSBCH。
具体地，基于第一信息生成PSBCH RS，例如可以基于第一信息确定伪随机扰码序列的初始值c
init，该信息包括Sync Resourece序号(例如2bit)、slot index和S-SSB index中的至少一种的至少部分比特。
下面以参考信号为PSBCH DMRS为例，对本发明的技术方案进行进一步说明。
实施例一：
本实施例中，PSBCH DMRS的伪随机扰码序列的初始值c
init中只携带Sync Resource序号，则PSBCH DMRS序列生成方式如下：
其中，r(m)为PSBCH DMRS序列，c(*)为伪随机扰码序列，其初始化方 式包含如下式子中的至少一项：
其中，A，B，C，D，E，a1-a10为正整数。
具体地，初始化方式包含如下式子中的至少一项：
其中，c
init为伪随机扰码序列的初始值，
包括第一信息中Sync Resource的序号的至少部分比特的值，例如2bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。接收端终端通过检测确定当前收到的S-SSB所在Sync Resource的序号，即可确定哪些Sync Resource用于发送，哪些Sync Resource用于接收(例如测得参考信号接收功率(Reference Signal Receiving Power，RSRP)强的Sync Resource用于收，测得RSRP弱的Sync Resource用于发)，不必再解码全部PSBCH才能获知收到的S-SSB所属的Sync Resource，降低PSBCH的解码复杂度。
实施例二：
本实施例中，PSBCH DMRS的伪随机扰码序列的初始值c
init中只携带S-SSB index信息，则PSBCH DMRS序列生成方式如下：
其中，r(m)为PSBCH DMRS序列，c(*)为伪随机扰码序列，其初始化方式包含如下式子中的至少一项：
c
init＝i
S-SSB+b10；
其中，F，G，H，I，J，b1-b10为正整数。
具体地，初始化方式包含如下式子中的至少一项：
c
init＝i
S-SSB+1；
其中，i
S-SSB包含第一信息中S-SSB索引的至少部分比特的值，例如2bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。这样，接收端终端通过检测当前收到的PSBCH DMRS序列，可提前获取至少部分定时信息，并降低PSBCH中的定时信息开销。
实施例三：
本实施例中，PSBCH DMRS的伪随机扰码序列的初始值c
init中只携带slot index信息，则PSBCH DMRS序列生成方式如下：
其中，r(m)为PSBCH DMRS序列，c(*)为伪随机扰码序列，其初始化方式包含如下式子中的至少一项：
c
init＝i
Slot+c10；
其中，K，L，M，N，O，c1-c10为正整数。
具体地，初始化方式包含如下式子中的至少一项：
c
init＝i
Slot+1；
其中，i
Slot包含第一信息中slot索引的至少部分比特的值，例如3bit或者4bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。这样，接收端终端通过检测当前收到的PSBCH DMRS序列，可提前获取至少部分定时信息，并降低PSBCH中的定时信息开销。
实施例四：
本实施例中，PSBCH DMRS的伪随机扰码序列的初始值c
init中携带Sync Resource序号、slot index和S-SSB index中的两种信息，则PSBCH DMRS序列生成方式如下：
其中，r(m)为PSBCH DMRS序列，c(*)为伪随机扰码序列。
a)在第一信息包括Sync Resource序号和S-SSB index时，c
init初始化方式包含如下式子中的至少一项：
其中，A1-A10，d1-d16为正整数。
具体地，c

其中，
包含Sync Resource的序号的至少部分比特，例如2bit，i
S-SSB包含第一信息中S-SSB索引的至少部分比特的值，例如2bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。这样，接收端终端根据检测到的Sync Resource序号和S-SSB index可确定至少部分定时信息甚至可以确定完整的定时信息，从而节省PSBCH中定时信息的开销。并且当可确定完整的定时信息时，用户不必再解码PSBCH来获取定时信息，降低PSBCH的解码复杂度。FR1时，2bit Sync Resource序号+4bit S-SSB index<7bit slot index，降低了PSBCH中的定时信息开销；FR2时，2bit Sync Resource序号+6bit S-SSB index＝8bit，由于该信息中的至少部分比特(例如3bit)由DMRS携带，同样降低了PSBCH中的定时信息开销。
b)在第一信息包括Sync Resource序号和slot index时，c
init初始化方式包含如下式子中的至少一项：
其中，A11-A20，d17-d32为正整数。
具体地，c
init初始化方式包含如下式子中的至少一项：
其中，i
Slot包含第一信息中slot索引的至少部分比特的值，例如3bit或者4bit的值，
包括Sync Resource的序号的至少部分比特，例如2bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。这样，接收端终端根据检测到的Sync Resource序号和S-SSB index可确定至少部分定时信息，降低了PSBCH的解码复杂度和PSBCH中的定时信息开销。
c)在第一信息包括S-SSB index和slot index时，c
init初始化方式包含如下式子中的至少一项：
c
init＝2
A29(i
S-SSB+d47)+i
Slot；
c
init＝2

其中，A21-A30，d33-d48为正整数。
具体地，c

S-SSB+1)+i
Slot；
c
init＝2
2(i
S-SSB+1)+i

S-SSB包含第一信息中S-SSB索引的至少部分比特的值，例如2bit的值，
包含旁链路同步序列携带的标识的至少部分比特的值，例如全部比特的值。这样，接收端终端根据检测到的S-SSB index和slot index可确定至少部分定时信息，并降低了PSBCH中的定时信息开销。
实施例五：
本实施例中，PSBCH DMRS的伪随机扰码序列的初始值c
init中携带Sync Resource序号、slot index和S-SSB index共三种信息，则PSBCH DMRS序列生成方式如下：
其中，r(m)为PSBCH DMRS序列，c(*)为伪随机扰码序列，其初始化方式包含如下式子中的至少一项：
其中，B1-B48，e1-e66为正整数。
