相关申请的交叉引用
本申请主张在2019年8月9日在中国提交的中国专利申请No.201910736211.4的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种上行资源的配置方法、网络侧设备及用户设备。
背景技术
在相关技术中的切换过程中,目标小区为UE(User Equipment,用户设备)生成切换命令后,通过源小区发送给UE。其中切换命令中包含目标小区为UE配置的无线资源的配置信息、为UE分配的UE ID C-RNTI(Cell Radio Network Temporary Identifier,小区无线网络临时标识)、控制切换的定时器T304以及可能包含目标小区为UE分配的专用的随机接入资源。UE接收到切换命令后,则开启定时器T304,按照切换命令配置UE,UE同步到目标小区,RRC(Radio Resource Control,无线资源控制)层将切换完成消息递交给底层,然后发送给目标小区,MAC(Medium Access Control,媒体接入控制)层触发随机接入过程。如果切换命令中携带专用的随机接入信息则触发非竞争的随机接入过程,否则触发竞争的随机接入过程。竞争解决后,切换完成,停止定时器T304,MAC层将切换完成消息发送给目标小区。
其中,在LTE系统中,引入RACH-less(Random Access Channel less,跳过随机接入信道)过程的切换,以缩短切换时延。其中,RACH-less方案即UE不需要触发随机接入过程而接入目标小区。不同于相关技术中的切换过程,目标小区在切换命令中包含执行RACH-less的指示信息,以及对应的TA信息,并且切换命令中还可以包含预配置的周期性上行资源用于UE发送上行消息。
然而,相关技术中并不是所有小区都可以配置RACH-less,只有当目标小区的TA为0ms或者目标小区的TA与当前服务的主小区的TA相同,或者与当前服务小区某TA组的TA相同,目标小区才可以为UE配置RACH-skip。并且如果目标小区为UE配置了预配置的上行资源,该上行资源为周期性上行资源,如果UE接入较晚则会造成资源浪费。并且,对于NTN(Non-Terrestrial Network,非地面网络)系统,小区覆盖较大,UE数量较多,如果目标小区为每个UE都预留周期性上行资源则可能造成较高的资源浪费。

在网络侧设备为UE配置定时提前量参考小区和与所述参考小区的定时提前量的时差的情况下,UE根据参考小区的TA结合参考小区与UE所接入的小区的时差计算出UE所要接入小区的TA,从而调整上行的发送时刻,在配置的可用的上行资源内发送上行数据到UE所要接入的小区。

可选地,所述定时提前量的配置信息包括:
定时提前量;
或者

其中,在网络侧设备为UE配置定时提前量的情况下,在UE获得所要接入的小区的定时提前量后,按照提供的定时提前量调整上行的发送时刻,在配置的可用的上行资源内发送上行数据到该小区。
在网络侧设备为UE配置定时提前量参考小区和与所述参考小区的定时提前量的时差的情况下,UE根据参考小区的TA结合参考小区与UE所接入的小区的时差计算出UE所要接入小区的TA,从而调整上行的发送时刻,在配置的可用的上行资源内发送上行数据到UE所要接入的小区。
可选地,网络侧设备可以根据以下信息计算获得TA:
UE的地理位置信息;
源小区或指定服务小区与目标小区之间的地理位置关系;

可选地,还包括:

周期内上行资源所在的SFN和/或所在的slot;
周期内上行资源所在的SFN和/或所在的子帧;

有效时间内具体的有效的子帧位置的起始时刻和/或有效符号位置的起始时刻;
上行资源所在的时隙或子帧内有效的符号的持续个数;
上行资源所在的SFN内有效的时隙或子帧的持续个数;
其中,考虑到NR系统支持多波束场景,所以上行资源的配置信息还可以包含同步信号块索引(SSB index),以关联相关的SSB。
可选地,所述有效期信息可以通过bitmap(比特图)和/或具体的IE(信息元素)指示的形式进行表示。
可选地,所述接收网络侧设备发送的目标资源的有效期信息之后,还包括以下至少一项:

接收到上行数据被成功接收的反馈消息时,释放所述目标资源;
在随机接入完成时,释放所述目标资源。
即UE在以下场景中在所述目标资源的有效期结束之前需要释放所述目标资源:
在接收到PDCCH调度时,其中该PDCCH调度以该UE的CRNTI加扰;
第三定时器(例如T304或T307)超时时;
接收到上行数据被成功接收的反馈时,其中该反馈可以是HARQ的ACK响应或者ARQ的ACK响应;
随机接入过程完成时。
可选地,还包括:
接收网络侧设备配置的专用随机接入资源;
所述接收网络侧设备发送的目标资源的有效期信息之后,还包括以下其中一项:
C1:在所述目标资源的有效期内,在所述目标资源上发送上行数据,且在所述目标资源的有效期结束之前不触发随机接入,即所述目标资源的优先级总是高于专用RACH资源的优先级;
C2:忽略所述目标资源,触发随机接入,即专用RACH资源的优先级总是高于所述目标资源的优先级;
C3:接收网络侧设备发送的指示信息,并根据所述指示信息触发随机接入或者在所述目标资源上发送上行数据,所述指示信息用于指示所述目标资源与所述专用随机接入资源的优先级,即根据网络侧设备的指示优先级进行处理,例如网络侧指示专用随机接入资源优先级高于预配置的上行资源,则UE优先触发随机接入过程,该指示同样适用于多波束场景下选择的波束中同时存在专用随机接入资源和目标资源时,UE根据网络指示的优先级进行处理;
C4:在所述目标资源的有效期开始之前和/或所述目标资源的有效期结束之后,触发随机接入;
C5:选择接入的第一波束上如果存在有效的所述目标资源的配置,则在所述目标资源的有效期内,在所述目标资源上发送上行数据,否则触发随机接入。考虑多波束场景,选择接入的beam上可能不存在某些专用配置,例如该波束上不存在预配置的上行资源,则UE触发随机接入过程,如果该波束上存在预配置的上行资源,则在指定的有效时间内按照配置的上行资源发送上行数据到接入小区;
C6:选择接入的第二波束上如果存在有效的专用的随机接入资源的配置,则在所述第二波束上触发随机接入。考虑多波束场景,选择接入的beam上可能不存在某些专用配置,例如该波束上不存在专用的随机接入资源只存在网络侧为UE配置的目标资源即上行资源,则UE在指定的有效时间按照配置的上行资源发送上行数据到接入小区,如果同时存在专用的随机接入资源和目 标资源时,则在该选择的波束上触发随机接入过程。
即在同时为UE预留上行资源且配置专用RACH资源的情况下,可以采用上述C1至C6中任一种方式进行处理。
可选地,所述接收网络侧设备发送的目标资源的有效期信息之后,还包括以下其中一项:
D1:在所述目标资源的有效期开始之前和/或所述有效期结束之后,触发随机接入;其中,具体地,如果配置了专用RACH资源,则在所述目标资源的有效期开始之前和/或所述有效期结束之后,触发非竞争随机接入;如果未配置专用RACH资源,则在所述目标资源的有效期开始之前和/或所述有效期结束之后,触发竞争随机接入;
D2:选择接入的第三波束上如果存在有效的所述目标资源的配置则在所述目标资源的有效期内,在所述目标资源上发送上行数据,否则触发随机接入。考虑多波束场景,选择接入的beam上可能不存在所述目标资源的配置,则此时UE在该beam上触发随机接入,如果配置了专用RACH资源,则在所述目标资源的有效期开始之前和/或所述有效期结束之后,触发非竞争随机接入;如果未配置专用RACH资源,则在所述目标资源的有效期开始之前和/或所述有效期结束之后,触发竞争随机接入。
即在为UE预留了上行资源的情况下,无论为UE是否配置了专用RACH资源,都可以采用上述D1和D2中任一方式进行处理。
当然,可以理解的是,还可规定不允许网络侧设备同时为UE预留上行资源,且配置专用RACH资源,或规定不允许网络侧设备为UE在同一个波束上同时配置预留上行资源且配置专用RACH资源。
可选地,还包括:
接收所述网络侧设备发送的第三定时器(例如T304或T307)的配置信息,所述第三定时器为用于控制小区切换或同步重配的定时器。
所述接收网络侧设备发送的目标资源的有效期信息之后,还包括以下其中一项:
E1:在接收到携带所述有效期信息的信令时,开启所述第三定时器;
E2:忽略所述第三定时器;
E3:在所述目标资源的有效期结束时开启所述第三定时器;
E4:在所述目标资源的有效期开始时开启所述第三定时器。
即在同时为UE预留上行资源且配置切换或同步重配等接入控制定时器时例T304或T307定时器的情况下,可以采用上述E1至E4中任一种方式进行处理。
当然,可以理解的是,还可规定不允许网络侧设备同时为UE预留上行资源,且配置用于控制小区切换或同步重配的定时器。
综上所述,本公开的实施例,能够为UE提供TA以及为UE预留的上行资源的有效期信息,由于相比较于提供重复的预留上行资源,提供具体的有效期信息,可以节省预留上行资源,能够在节省UE所要接入的小区的空口资源的前提下跳过随机接入过程切换到目标小区,并且可以使UE在与服务小区非同步的目标小区上跳过随机接入过程切换到目标小区。
