技术领域
本申请属于通信技术领域,具体涉及一种信息获取方法、信息发送方法、装置、终端及网络侧设备。
背景技术
定时提前(Timing Advance,TA)用于终端上行传输,目的是确保终端上行数据包在希望的时间内到达基站。目前在小区切换场景中,通常是终端在成功接收指示小区切换的高层命令以及完成下行同步、自动增益控制(Automatic Gain Control,AGC)调整后,向目标小区发送前导码,目标小区向终端反馈TA值的方式来获取TA值。由于终端在收到指示小区切换的高层信令后,便会中断与源小区的数据传输,而高层信令处理时间较长且下行同步也存在一定的时间开销,因此该方式使得终端与当前服务小区的中断时间较长。

每个候选对象的下行同步指示信息。
上述至少一个候选对象的配置信息可包括以一个候选对象为单位配置的每个候选对 象的所有配置信息,或者包括以一个候选对象为单位配置的每个候选对象的部分配置信息。对于后一种情况,每个候选对象的其余部分配置信息可以与第二对象的配置信息相同。候选对象的配置信息可包含高层配置信息和物理层相关配置信息中的至少一项,高层配置信息包括小区组配置信息CellGroupConfig、主小区配置信息SpCellConfig、携带同步的重配置信息ReconfigurationWithSync、服务小区的公共配置信息ServingCellConfigCommon、服务小区配置信息ServingCellConfig中的至少一项,物理层相关配置信息可包括传输配置指示(Transmission Configuration Indicator,TCI)、准共址(Quasi co-location,QCL)、路径损耗参考信号(Path Loss Reference Signal,PL RS)、随机接入信道(Random Access Channel,RACH)资源、扰码信息、频域信息(如同步信号/物理广播信道信号块(或同步信号块)(Synchronization Signal and PBCH block,SSB)频点、CSI参考信号((Channel State Information,CSI)-Reference Signal,CSI-RS)频点以及频带指示)、子载波间隔(subcarrier spacing,SCS)、信道探测参考信号(Sounding Reference Signal,SRS)中的至少一项。
上述每个候选对象与所述第二对象的参考定时差可配置如下:其一,配置参考定时差且参数值不为零或大于第一阈值,该种配置可表示候选对象与所述第二对象非同步;其二,缺省参考定时差,或者,配置参考定时差且参数值为零或小于第一阈值,该种配置可表示候选对象与所述第二对象同步。这里,第一阈值可由网络侧设备配置或按照协议约定或根据终端能力确定。候选对象与第二对象的参考定时差的精度可以为帧、时隙、正交频分复用(Orthogonal frequency division multiplex,OFDM)符号、秒、毫秒、微秒、纳秒中的至少一项。候选对象与第二对象的参考定时差可配置于候选对象的配置信息中。
上述每个候选对象的上行同步指示信息可以指示候选对象对应的定时提前组(Timing Advance Group,TAG)标识,或者指示候选对象和第一对象是否属于不同的TAG。上述每个候选对象的上行同步指示信息可以是1比特指示信息,其中,0表示上行同步,1表示非上行同步,或者,上述每个候选对象的上行同步指示信息为Bool类型的信息,其中,true表示上行同步,false表示非上行同步。或者,在配置了该上行同步指示信息的情况下表示非上行同步,在缺省该参数的情况下可默认为上行同步。候选对象的上行同步指示信息可配置于候选对象的配置信息中。
以下对第二信令进行相关说明:
第二信令可包含媒体接入控制层控制单元(Medium Access Control Control Element,MAC CE)和下行控制信息(Downlink Control Information,DCI)中的其中一项,其中,DCI可包括下行DCI(DL DCI)和上行DCI(UL DCI)中的至少一个。第二信令指示第一对象的方式至少包括如下两种:其一,第二信令包括目标域,该目标域用于指示第一对象,也就是说,第二信令存在一个用于指示第一对象的域;其二,第二信令包括波束指示信息,该波束指示信息与第一对象关联,也就是说,第二信令中携带的波束指示信息关联第一对象,波束指示信息可以包括传输配置指示(Transmission Configuration Indicator,TCI)状态(即TCI state)、联合TCI(Joint TCI)、DL TCI、UL TCI或空间关系(Spatial relation)。 终端可根据第二信令从第一信令中包含的候选对象中确定第一对象,第一对象的标识指示与第二对象的标识指示相同或不同。
对于第二信令与第三信令为同一信令的情况,上述第二信令的相关说明适用于第三信令。在此情况下,终端可根据第二信令中携带的波束指示信息对应的准共址源参考信号(Reference Signal,RS)所关联的RACH资源,获得终端在第一对象下的TA值。
对于第二信令与第三信令为同一信令的情况,第二信令还可携带TA值。这样,终端可以将第二信令中携带的TA值,确定为终端在第一对象下的TA值。
对于第二信令与第三信令为不同信令的情况,以下对第三信令进行相关说明:
第三信令用于激活至少一个对象的至少一个RACH资源,所述激活的RACH资源用于获取所述至少一个对象的TA值。

其中,所述至少一个对象包括所述第一对象。
作为示例,第三信令可激活的RACH资源可以是基于竞争的随机接入(Contention Based Random Access,CBRA)或非竞争随机接入(Contention Free Random Access,CFRA),当Preamble index为0,可表示第三信令激活的RACH资源为CBRA,当Preamble index不为0,可表示第三信令激活的RACH资源为CFRA。
本申请实施例中,对于终端根据目标信令获得终端在第一对象下的TA值的相关方案,可以是终端根据第一信令和第二信令来获得终端在第一对象下的TA值,也可以是终端根据第二信令来获得终端在第一对象下的TA值,也可以是终端根据第三信令来获得终端在第一对象下的TA值,还可以是终端根据目标信令所发送的SRS,并由网络侧设备发送TA值的方式来获得终端在第一对象下的TA值,还可以是终端根据目标信令发送前置信号并由网络侧设备发送TA值的方式来获得终端在第一对象下的TA值。以下分别对这些可选的实施方式进行说明:
作为一种实施方式,所述终端根据所述目标信令,获得所述终端在第一对象下的TA值,包括:
所述终端根据所述第一信令和所述第二信令,确定所述第一对象与第二对象的参考定时差以及所述第一对象与第二对象的下行接收时间差;
所述终端根据所述第二对象的TA值、所述第一对象与第二对象的参考定时差、所述 第一对象和第二对象的下行接收时间差,确定所述终端在第一对象下的TA值。
该实施方式具体适用于第一对象与第二对象非同步的情况。该情况下,第一对象与第二对象之间存在参考定时差和下行接收时间差,终端可根据第二对象的TA值、第一对象与第二对象的参考定时差、第一对象和第二对象的下行接收时间差这三个参数来确定终端在第一对象下的TA值。
需要说明的是,由于第二对象为当前服务对象,因此第二对象的TA值已经被终端预先获取到了。
如前所述,第一信令用于指示多个对象的配置信息,作为示例,第一对象与第二对象的参考定时差和/或第一对象与第二对象的下行接收时间差均可以包含在第一信令指示的多个对象的配置信息中。
该实施方式中,终端根据第一信令和第二信令这两个信令来确定终端在第一对象下的TA值。
作为另一种实施方式,所述终端根据所述目标信令,获得所述终端在第一对象下的TA值,包括:
所述终端根据所述第一信令和所述第二信令,获得所述终端在第一对象下的TA值,其中,所述终端在第一对象下的TA值和所述终端在第二对象下的TA值相同。
这里,第二对象的TA可由网络侧设备通过legacy的随机接入响应(Random Access Response,RAR)或MAC CE告知终端。作为示例,第一信令中包含的上行同步指示信息和下行同步指示信息用于指示每个候选小区的TA值是否与第二对象的TA值相同,第二信令用于确定第一对象,因此,终端可根据第一信令和第二信令来判断第一对象的TA值是否与第二对象的TA值相同。该实施方式具体适用于第一对象的TA值与第二对象的TA值相同的情况,即第一对象和第二对象同步的情况。该情况下,终端在第一对象下的TA值与其在第二对象下的TA值相同,终端可以将在第二对象下的TA值作为在第一对象下的TA值。
该实施方式中,终端根据第一信令和第二信令这两个信令来确定终端在第一对象下的TA值。
作为又一种实施方式,所述第二信令携带TA值;所述终端根据所述目标信令,获得所述终端在所述第一对象下的TA值,包括:
所述终端将所述第二信令中携带的TA值,确定为所述终端在所述第一对象下的TA值。
作为再一种实施方式,所述终端根据所述目标信令,获得所述终端在第一对象下的TA值,包括:
所述终端根据第三信令中携带的TA值确定第一对象的TA值。
该实施方式中,第三信令还可携带至少第一对象的标识。
作为另一种实施方式,所述目标信令包括所述第一信令,所述终端根据所述目标信令, 获得所述终端在第一对象下的定时提前TA值,包括:
所述终端根据所述目标信令,向所述网络侧设备发送SRS,所述SRS用于获取所述终端在至少一个对象下的TA值;
所述终端接收第二信令,获得所述终端在第一对象下的定时提前TA值,所述第二信令携带所述终端在至少一个对象下的目标信息,所述目标信息包括TA值,或者所述目标信息包括TA值以及TA值对应的对象标识,或者所述目标信息包括TA组标识和TA值,所述TA组标识用于指示第一TA组,所述第一TA组关联所述至少一个对象,所述TA值为所述终端在所述第一TA组关联的所述至少一个对象下的TA值。其中,所述第一TA组与所述至少一个对象的关联关系由网络显式或隐式地配置,所述至少一个对象包括所述第一对象。终端可从所述第二信令携带的信息中获取所述终端在第一对象下的TA值。具体地,TA组标识可以为通过O个比特指示,其中O的取值为K为所述终端在所述第一对象下可维护的TA组最大数量,或者为所述终端在所述至少一个对象下可维护的的TA组的最大数量。
该实施方式中,SRS可以由终端根据第一信令中的配置信息确定,或者在所述目标信令还包括第三信令的情况下,SRS由第三信令激活。
