Abstract

Description

由用户设备执行的方法以及用户设备 技术领域
本发明涉及无线通信技术领域，具体涉及由用户设备执行的方法以及相应的用户设备。
背景技术
在传统的蜂窝网络中，所有的通信都必须经过基站。不同的是，D2D通信(Device-to-Device communication，设备到设备间直接通信)是指两个用户设备之间不经过基站或者核心网的转发而直接进行的通信方式。在2014年3月第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)的RAN#63次全会上，关于利用LTE设备实现临近D2D通信业务的研究课题获得批准(参见非专利文献1)。LTE Release 12 D2D引入的功能包括：
1)LTE网络覆盖场景下临近设备之间的发现功能(Discovery)；
2)临近设备间的直接广播通信(Broadcast)功能；
3)高层支持单播(Unicast)和组播(Groupcast)通信功能。
在2014年12月的3GPP RAN#66全会上，增强的LTE eD2D(enhanced D2D)的研究项目获得批准(参见非专利文献2)。LTE Release 13 eD2D引入的主要功能包括：
1)无网络覆盖场景和部分网络覆盖场景的D2D发现；
2)D2D通信的优先级处理机制。
基于D2D通信机制的设计，在2015年6月3GPP的RAN#68次全会上，批准了基于D2D通信的V2X可行性研究课题。V2X表示Vehicle to everything，希望实现车辆与一切可能影响车辆的实体信息交互，目的是减少事故发生，减缓交通拥堵，降低环境污染以及提供其他信息服务。V2X的应用场景主要包含4个方面：
1)V2V，Vehicle to Vehicle，即车-车通信；
2)V2P，Vehicle to Pedestrian，即车给行人或非机动车发送警告；
3)V2N，Vehicle to Network，即车辆连接移动网络；
4)V2I，Vehicle to Infrastructure，即车辆与道路基础设施等通信。
3GPP将V2X的研究与标准化工作分为3个阶段。第一阶段于2016年9月完成，主要聚焦于V2V，基于LTE Release 12和Release 13 D2D(也可称为sidelink侧行通信)，即邻近通信技术制定(参见非专利文献3)。V2X stage 1引入了一种新的D2D通信接口，称为PC5接口。PC5接口主要用于解决高速(最高250公里/小时)及高节点密度环境下的蜂窝车联网通信问题。车辆可以通过PC5接口进行诸如位置、速度和方向等信息的交互，即车辆间可通过PC5接口进行直接通信。相较于D2D设备间的临近通信，LTE Release 14 V2X引入的功能主要包含：
1)更高密度的DMRS以支持高速场景；
2)引入子信道(sub-channel)，增强资源分配方式；
3)引入具有半静态调度(semi-persistent)的用户设备感知(sensing)机制。
V2X研究课题的第二阶段归属于LTE Release 15研究范畴(参见非专利文献4)，引入的主要特性包含高阶64QAM调制、V2X载波聚合、短TTI传输，同时包含发射分集的可行性研究。
在2018年6月3GPP RAN#80全会上，相应的第三阶段基于5G NR网络技术的V2X可行性研究课题(参见非专利文献5)获得批准。
在2019年8月3GPP RAN1#98次会议上(参见非专利文献6)，关于NR sidelink中传输传输模式1的调度，达成了如下会议结论：
对于NR sidelink传输模式1的调度，既支持相同载波(sidelink载波和Uu载波相同的情况)的调度，也支持跨载波调度(cross-carrier scheduling)。
本发明的方案包括NR侧行通信中传输模式1的UE确定PSCCH/PSSCH传输时隙的方法。
在2019年5月3GPP RAN1#97次会议上(参见非专利文献7)，关于NR sidelink传输模式1的HARQ反馈，达成了如下会议结论：
在NR sidelink传输模式1中，支持发送用户设备将接收到的侧行通 信HARQ反馈信息发送到基站gNB。发送用户设备通过PUCCH发送接收到的HARQ反馈信息。
在2019年8月3GPP RAN1#98次会议上(参见非专利文献6)，关于上述PUCCH资源的指示，达成了如下会议结论：
基站gNB在承载DCI的PDCCH中指示用于传输侧行通信HARQ反馈信息的PUCCH的定时关系(timing)和资源(resource)。
本发明的方案也包括NR侧行通信中传输模式1的发送(transmitter)UE确定PUCCH传输时隙的方法。
根据上述关于NR sidelink中传输传输模式1的调度的会议结论(参见非专利文献6)，在NR sidelink中支持跨载波调度，即NR载波和sidelink载波是两个不同的载波。这意味着如果侧行通信UE在sidelink载波上的同步源是除该UE所在的服务小区(serving cell)以外的同步源，例如其他UE、GNSS等，则NR载波上的时序(timing)和sidelink载波上的时序(timing)不一定相同。类似地，NR载波上的TDD配置和sidelink载波上的TDD配置不一定相同。
本发明的方案同样包括一种侧行通信UE向基站上报sidelink载波上的时序timing，以及sidelink载波上的TDD配置的方法。

Sidelink通信的场景
1)无网络覆盖(Out-of-Coverage)侧行通信：进行sidelink通信的两个UE都没有网络覆盖(例如，UE在需要进行sidelink通信的频率上检测不到任何满足“小区选择准则”的小区，表示该UE无网络覆盖)。
2)有网络覆盖(In-Coverage)侧行通信：进行sidelink通信的两个 UE都有网络覆盖(例如，UE在需要进行sidelink通信的频率上至少检测到一个满足“小区选择准则”的小区，表示该UE有网络覆盖)。
3)部分网络覆盖(Partial-Coverage)侧行通信：进行sidelink通信的其中一个UE无网络覆盖，另一个UE有网络覆盖。
从UE侧来讲，该UE仅有无网络覆盖和有网络覆盖两种场景。部分网络覆盖是从sidelink通信的角度来描述的。
LTE V2X(sidelink)通信的基本过程
图1是示出了LTE V2X UE侧行通信的示意图。首先，UE1向UE2发送侧行通信控制信息(SCI format 1)，由物理层信道PSCCH携带。SCI format 1包含PSSCH的调度信息，例如PSSCH的频域资源等。其次，UE1向UE2发送侧行通信数据，由物理层信道PSSCH携带。PSCCH和相应的PSSCH采用频分复用的方式，即PSCCH和相应的PSSCH在时域上位于相同的子帧上，在频域上位于不同的RB上。PSCCH和PSSCH的具体设计方式如下：
1)PSCCH在时域上占据一个子帧，频域上占据两个连续的RB。加扰序列的初始化采用预定义数值510。PSCCH中可携带SCI format 1，其中SCI format 1至少包含PSSCH的频域资源信息。例如，对于频域资源指示域，SCI format 1指示该PSCCH对应的PSSCH的起始sub-channel编号和连续sub-channel的数目。
2)PSSCH在时域上占据一个子帧，和对应的PSCCH采用频分复用(FDM)。PSSCH在频域上占据一个或者多个连续的sub-channel，sub-channel在频域上表示n subCHsize个连续的RB，n subCHsize由RRC参数配置，起始sub-channel和连续sub-channel的数目由SCI format 1的频域资源指示域指示。
LTE V2X的资源分配方式Transmission Mode 3/4
图2是示出了LTE V2X的两种资源分配方式，分别称为基于基站调度的资源分配(Transmission Mode 3)和基于UE感知(sensing)的资源分配(Transmission Mode 4)。LTE V2X中，当存在eNB网络覆盖的情况下，基站可通过UE级的专有RRC信令(dedicated RRC signaling)SL-V2X-ConfigDedicated配置该UE的资源分配方式，或称为该UE的传输模式，具体为：
1)基于基站调度的资源分配方式(Transmission Mode 3)：基于基站调度的资源分配方式表示sidelink侧行通信所使用的频域资源来自于基站的调度。传输模式3包含两种调度方式，分别为动态调度和半静态调度(SPS)。对于动态调度，UL grant(DCI format 5A)中包括PSSCH的频域资源，承载DCI format 5A的PDCCH或者EPDCCH的CRC由SL-V-RNTI加扰。对于SPS半静态调度，基站通过IE：SPS-ConfigSL-r14配置一个或者多个(至多8个)配置的调度许可(configured grant)，每个配置的调度许可含有一个调度许可编号(index)和调度许可的资源周期。UL grant(DCI format 5A)中包括PSSCH的频域资源，以及，调度许可编号的指示信息(3bits)和SPS激活(activate)或者释放(release，或者，去激活)的指示信息。承载DCI format 5A的PDCCH或者EPDCCH的CRC由SL-SPS-V-RNTI加扰。
具体地，当RRC信令SL-V2X-ConfigDedicated置为scheduled-r14时，表示该UE被配置为基于基站调度的传输模式。基站通过RRC信令配置SL-V-RNTI或者SL-SPS-V-RNTI，并通过PDCCH或者EPDCCH(DCI format 5A，CRC采用SL-V-RNTI加扰或者采用SL-SPS-V-RNTI加扰)向UE发送上行调度许可UL grant。上述上行调度许可UL grant中至少包含sidelink通信中PSSCH频域资源的调度信息。当UE成功监听到由SL-V-RNTI加扰或者SL-SPS-V-RNTI加扰的PDCCH或者EPDCCH后，将上行调度许可UL grant(DCI format 5A)中的PSSCH频域资源指示域作为PSCCH(SCI format 1)中PSSCH的频域资源的指示信息，并发送PSCCH(SCI format 1)和相应的PSSCH。
对于传输模式3中的半静态调度SPS，UE在下行子帧n上接收SL-SPS-V-RNTI加扰的DCI format 5A。如果DCI format 5A中包含SPS激活的指示信息，该UE根据DCI format 5A中的指示信息确定PSSCH的频域资源，根据子帧n等信息确定PSSCH的时域资源(PSSCH的发送子帧)。
2)基于UE感知(sensing)的资源分配方式(Transmission Mode 4)：基于UE sensing的资源分配方式表示用于sidelink通信的资源基于UE对候选可用资源集合的感知(sensing)过程。RRC信令SL-V2X-ConfigDedicated置为ue-Selected-r14时表示该UE被配置为基于UE sensing的传输模式。在基于UE sensing的传输模式中，基站配置可用的传输资源池，UE根据一定的规则(详细过程的描述参见LTE V2X UE sensing过程部分)在传输资源池(resource pool)中确定PSSCH的sidelink发送资源，并发送PSCCH(SCI format 1)和相应的PSSCH。
侧行通信资源池(sidelink resource pool)
在侧行通信中，UE的发送和接收的资源均属于资源池resource pool。例如，对于侧行通信中基于基站调度的传输模式，基站在资源池中为sidelink UE调度传输资源，或者，对于侧行通信中基于UE感知的传输模式，UE在资源池中确定传输资源。
UE的服务小区(serving cell)
在NR通信系统中，支持载波聚合(Carrier Aggregation)。在载波聚合场景下，UE的服务小区serving cell可能多于一个，包括1个主小区PCell(Primary Cell)和一个或者多个辅小区SCell(Secondary Cell)。其中，当UE进行初始接入时，接入的小区可以称作主小区PCell，基站gNB通过高层RRC信令为该UE配置并激活辅小区SCell。
NR载波和sidelink载波
在本发明的说明书中涉及的载波均表示在频域上一段连续的频域资源。NR载波表示UE的服务小区serving cell工作的频率，在NR载波上，UE进行对于来自于基站的下行传输的接收和UE自身的上行传输等。Sidelink载波表示UE进行侧行通信发送和接收所在的频率。在本发明的说明书中涉及的sidelink载波可以表示NR sidelink载波，或者，LTE sidelink载波。在NR sidelink载波上，UE进行NR侧行通信的传输和接收；在LTE sidelink载波上，UE进行LTE侧行通信的传输和接收。两个相同的载波表示两个载波占据的频域资源完全相同；如果两个载波的频域资源之间不完全重合，那么，这两个载波称作不同的载波。
V2X UE的同步源
同步源(synchronization source)可简称为sync source，或者简称为sync reference。在LTE V2X中，和蜂窝网络通信的机制相似，若UE有数据需要传输，则UE首先需要进行时域和频域的同步。在蜂窝网络通信中，当UE接收主同步PSS和辅同步信号SSS后，可以确定小区的定时关系(或者称为时序timing)。时序timing包含帧定时的同步(10ms定时)，和子帧(或者，时隙slot)的定时同步。具体来讲，以时域同步为例，在LTE中，UE根据接收的PSS和SSS确定帧同步和子帧同步；在NR中，UE根据同步系统信息块SSB的编号和预定义的SSB的映射方式确定帧同步和子帧/时隙同步。对于V2X或者sidelink通信，UE根据选择的同步源的定时关系timing确定sidelink或者V2X发送或者接收的定时关系。对于LTE V2X，UE需要选择同步源。可能的同步源包括：
1)eNB；
2)GNSS；
3)LTE sidelink UE。
UE根据预定义一定的优先级准则确定同步源(Synchronization Source)。该优先级准则包括但不限于：基站eNB的优先级高于sidelink  UE，sidelink UE中发送信号RSRP高的优先级较高等。即在其他条件相同的情况下，UE相较于sidelink UE优先选择基站eNB作为同步源。本发明的实施例中如果涉及UE选择同步源，则默认UE会根据一定的优先级准则确定同步源。
NR中(包含NR sidelink)的参数集合(numerology)和NR中(包含NR  sidelink)的时隙slot
参数集合numerology包含子载波间隔和循环前缀CP长度两方面含义。其中，NR支持5种子载波间隔，分别为15k，30k，60k，120k，240kHz(对应μ＝0，1，2，3，4)，表格4.2-1示出了支持的传输参数集合，具体如下所示。
表4.2-1 NR支持的子载波间隔
μ Δf＝2 μ·15[kHz] CP(循环前缀)
0 15 正常
1 30 正常
2 60 正常，扩展
3 120 正常
4 240 正常
仅当μ＝2时，即60kHz子载波间隔的情况下支持扩展(Extended)CP，其他子载波间隔的情况仅支持正常CP。对于正常(Normal)CP，每个时隙(slot)含有14个OFDM符号；对于扩展CP，每个时隙含有12个OFDM符号。对于μ＝0，即15kHz子载波间隔，1个时隙＝1ms；μ＝1，即30kHz子载波间隔，1个时隙＝0.5ms；μ＝2，即60kHz子载波间隔，1个时隙＝0.25ms，以此类推。
NR和LTE对于子帧(subframe)的定义相同，表示1ms。对于子载波间隔配置μ，1个子帧内(1ms)的slot编号可以表示为
Figure PCTCN2020117366-appb-000007
范围为0到
Figure PCTCN2020117366-appb-000008
1个系统帧(frame，时长10ms)内的slot编号可以表示为

范围为0到

其中，

和

在不同子载波间隔μ的情况的定义如下表格所示。
表格4.3.2-1：正常CP时每个slot包含的符号数，每个系统帧包含的slot数，每个子帧包含的slot数

Figure PCTCN2020117366-appb-000014
在NR载波上，系统帧(或者，简称为帧)的编号SFN范围为0至1023。在侧行通信中引入了直接系统帧号DFN的概念，编号范围同样为0至1023，上述对于系统帧和numerology之间关系的叙述同样可以应用于直接系统帧，例如，一个直接系统帧的时长同样等于10ms，对于15kHz的子载波间隔，一个直接系统帧包括10个时隙slot，等等。DFN应用于sidelink载波上的定时timing。
NR TDD配置信息的指示和确定方法
NR基站gNB通过SIB1中的TDD-UL-DL-ConfigCommon配置小区级的TDD配置信息，其中包括：

对于扩展CP(Extended CP)，
Figure PCTCN2020117366-appb-000019
SIBl中的TDD-UL-DL-ConfigCommon可能包含高层参数pattern2(该信息元素为Optional可选，表示TDD配置样式2，下同)。pattern2和patternl的配置信息形式相同(pattern2的参数包括：周期P2，d slots，2，u slots，2，d sym，2，u sym，2)，相应的参数含义与对应的pattern1参数相同。参考子载波间隔μ ref和pattern1相同，因此对于pattern2不会重复配置参考子载波间隔μ ref。上述配置信息的周期为P2 ms，对应连续的

个时隙。在S2个时隙中，首先是d slots，2个下行时隙，u slots，2个上行时隙位于S2个时隙的最后。d svm，2个下行OFDM符号位于下行时隙后，u sym，2个上行OFDM符号位于上行时隙前，其余的
Figure PCTCN2020117366-appb-000021
Figure PCTCN2020117366-appb-000022
个OFDM符号为X符号(X表示flexible符号)。X符号在不同的应用场景中可能为下行符号，或者上行符号，或者作为下行上行之间的保护间隔符号。其中，对于正常CP(Normal CP)，
Figure PCTCN2020117366-appb-000023
对于扩展CP(Extended CP)，
Figure PCTCN2020117366-appb-000024
当TDD-UL-DL-ConfigCommon同时包含pattern1和pattern2时，该TDD配置信息的配置周期为(P+P2)ms，包含上述的S和S2个时隙(时域上首先为S，其次为S2)。
上述配置信息中的周期P和P2需满足如下条件：
1)P为20的约数，即P可被20整除，同时需满足每20/P个周期的首个时域符号是偶数帧的首个符号；
2)P+P2为20的约数，即P+P2可被20整除，同时需满足每20/(P+P2)个周期的首个时域符号是偶数帧的首个符号。
P和P2的可取值范围包括{0.5，0.625，1，1.25，2，2.5，5，10}ms。P和 P2的取值也包含3ms和4ms，由IE：dl-UL-TransmissionPeriodicity-v1530表示。当基站在pattern1/2中配置了dl-UL-TransmissionPeriodicity-v1530时，UE忽略对应pattern1/2的dl-UL-TransmissionPeriodicity。
LTE TDD上下行配置信息
LTE支持共7种TDD上下行配置信息(也可称作TDD配置信息)，编号为TDD UL/DL Configuration 0～6，如下表格4.2-2所示。其中，“D”表示下行子帧(subframe)，“U”表示上行子帧，“S”表示特殊子帧(Special Subframe)。特殊子帧由下行符号(DwPTS)，保护间隔(Gap)，上行符号(UpPTS)组成，本发明与特殊子帧的具体配置无关联，此处不加赘述。LTE基站eNB在SystemInformationBlockType1(SIB1)中配置本小区的TDD上下行配置信息。

上行定时提前量Timing Advance(TA)
在蜂窝网络通信中，上行传输的一个重要特征是不同UE在时频上正交多址接入，即来自同一小区的不同UE的上行传输之间互不干扰。为此引入了上行定时提前量TA的概念。例如，当UE进行初始接入时，基站向该UE指示TA command(TA命令)，UE根据该TA指示确定发送上行的时刻。对于初始接入的过程，在LTE中，TA command含有11bits，TA指示(T A)的取值范围为0-1282，N TA＝T A×16；在NR中，TA command含有12bits，TA指示(T A)的取值范围为0-3846，N TA＝T A×16×64/2 μ，其中μ对应子载波间隔2 μ×15kHz。对于除初始接入的其他情况，在LTE中， TA command含有6bits，TA指示(T A)的取值范围为0-63，N TA＝N TA，old+(T A-31)×16，其中，N TA，old表示TA调整前的N TA的数值；在NR中，TA command含有6bits，TA指示(T A)的取值范围为0-63，N TA＝N TA，old+(T A-31)×16×64/2 μ，其中μ对应子载波间隔2 μ×15kHz，N TA，old表示TA调整前的N TA的数值。本发明说明书实施例中涉及的N TA包括但不限于上述N TA的确定方式。
在LTE中，最小时间粒度(time granularity)采用Ts表示，其中Ts＝1/(15*2048)＝1/30720(ms)；在NR中，最小时间粒度(time granularity)采用Tc表示，其中Tc＝1/(480*4096)(ms)，满足Ts＝64*Tc。
以下，对本发明所涉及的具体的示例以及实施例等进行详细说明。另外，如上所述，本公开中记载的示例以及实施例等是为了容易理解本发明而进行的示例性说明，并不是对本发明的限定。
