  • the TA of a specific UE to a specific cell changes according to factors such as the location of the UE, and therefore, each time the UE obtains the latest TA from the base station, it will start or restart a Time Advance Timer (TAT), when TAT When the timeout expires, the UE considers that the previously obtained TA is no longer valid.

  • the UE sends a Scheduling Request (SR) to the specific cell of the base station to request the uplink resource. If the base station does not respond to the SR, the UE may repeatedly send the SR, but may not exceed The maximum number of repetitions. If the UE sends the SR to the maximum number of repetitions, the UE considers that an SR failure has occurred. If the UE detects that the SR fails, the UE releases the uplink resource configuration and initiates a random access request to the base station.

Description

资源重配方法、 基站及用户设备 技术领域 本申请涉及通信领域, 尤其涉及一种资源重配方法、 基站及用户设备。 背景技术 若用户设备 (User Equipment, 简称为 UE) 需要和基站的某个小区进行上行通信, UE需要获得这个小区的时间提前(Time Advance, TA) 。特定 UE到特定小区的 TA随着 UE的位置等因素的变化而变化, 因此, UE每次从基站获得最新的 TA后会开启或者重启 一个时间提前定时器 (Time Advance Timer, TAT) , 当 TAT超时的时候, UE会认为之 前获得的 TA不再有效, 因此, 会释放上行资源配置, 终止除随机接入请求以外的一切 上行传输, 以避免不必要的上行干扰。 若 UE到多个小区的 TA相同, 则这多个小区归属 于同一个 TA组, 属于同一个 TA组的小区共享同一个 TAT。 对应于 UE维护的 TAT, 基站 也会维护一个定时器, 每次将最新的 TA发送给 UE后, 基站也会相应地开启或者重启自 身维护的这个定时器, 因此, 基站可以通过自身维护的定时器的状态推知 UE维护的对 应 TAT的状态。
若 UE有新的上行数据需要发送给基站, UE向该基站的特定小区发送调度请求 ( Scheduling Request, SR) 以请求上行资源, 若基站并未响应该 SR, UE可以重复发送 SR, 但是不得超过最大重复次数。 如果 UE发送 SR达到了最大重复次数, 则 UE认为发生 了 SR失败。 若 UE探测到 SR失败, UE会释放上行资源配置, 向基站发起随机接入请求。
UE发送 SR本身也是需要物理上行控制信道 (Physical Uplink Control Channel ,
PUCCH)资源的, 多数情况下,基站会事先将用于发送 SR的 PUCCH资源配置发送给 UE, 但是, 因为 PUCCH资源相对紧缺, 基站也可视 UE的上行业务等情况不事先为 UE分配用 于发送 SR的 PUCCH资源。
UE有上行数据到达但检测到 TAT超时, 或者检测到 SR失败, 或者检测到没有用于 发送 SR的 PUCCH资源后, 会向基站发起基于竞争的随机接入过程, 在这个过程中 UE获 得了更新的 TA和上行准予 (Uplink Grant, UL Grant) , 其中上行准予对应一块已分配 的上行资源, UE可以使用此上行资源发送上行数据或者缓存状态报告 (Buffer Status Report, 简称为 BSR)等控制信息; 然后, 基站可以向 UE发送重配消息, 该消息包含上行 资源配置,该上行资源配置具体包含以下至少一种配置:调度请求(Scheduling Request, SR) 配置、 探测 (Sounding) 参考信号配置和信道质量指示 (Channel Quality Indicator, CQI) 上报配置; UE根据该上行资源配置向基站发送 SR、 Sounding和 CQI。 在一种新型 网络部署中, UE可以同时和两个以上的基站通信, 其中一个基站可以称为主基站, 其 他基站可以称为辅基站。 主基站和辅基站之间有连接。
如果 UE检测到辅基站的 TAT超时, 或者 UE在辅基站上发生 SR失败, 或者 UE在辅基 站上没有发送 SR的 PUCCH资源, 根据现有技术, UE仅能向辅基站发起基于竞争的随机 接入过程, 然后辅基站可以向 UE发送重配消息。 但是, 现有技术中的辅基站可能不具 有重配功能, 从而使得重配过程失败。
另外, UE使用的基于竞争的随机接入过程时延较大, 且容易因为发生碰撞而失败, 从而会延误上行数据的发送, 使用户体验变差。 发明内容
