为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例提供的一种用户设备、 基站及载波利用方法, 适用于图 1 所示的由用户设备和基站组成的系统架构图, 该系统包括基站、 以及该基站 覆盖区域内的一个或多个用户设备, 当基站与所述覆盖区域内的用户设备进 行通信时, 需要利用载波实现二者之间的信号传输。 本发明实施例在实现信 号传输时, 可以进一步对非授权频谱或不同运营商之间的共享频谱进行有效 的利用, 从而进一步满足移动运营商对频谱资源的需求。 下面对本发明的各 个实施例进行具体的介绍。 参见图 2 , 为本发明实施例提供的用户设备的结构示意图, 该用户设备 包括:
载波配置模块 201 , 用于接收基站发送的辅载波的配置信息, 并根据所 述配置信息配置所述辅载波, 所述辅载波为非授权频段或共享频段中的载波 资源, 所述共享频段为授权给至少两个运营商共同使用的频段。
第一控制模块 202 , 用于在接收到所述基站发送的第一激活命令后, 激 活所述载波配置模块 201配置的辅载波以得到激活辅载波, 并控制打开自身 的射频 (Rad io Frequency , 筒称 RF )模块, 而不进行与所述激活辅载波相 关的操作。
本实施例中, 每个小区会配置有多个载波, 基站 (evo lved Node B, 筒 称 eNB )可以使用其所在小区的一个或多个载波, 但能够被用户设备 ( User Equipment , 筒称 UE )使用的载波是经 eNB配置的载波, 而配置的载波又进 一步被划分为激活的载波(所述激活的载波中又包括激活的主载波和激活的 辅载波, eNB可利用为 UE服务的激活的主载波或激活的辅载波向 UE发送所 述配置信息)与去激活的载波, UE只能在激活的载波上进行数据传输, 而在 去激活的载波上不进行任何数据传输。 当 eNB需要利用所述配置的辅载波进 行数据传输时, eNB可利用为 UE服务的主载波或已经激活的任一辅载波向 UE 发送所述第一激活命令。
本实施例中, 在载波配置模块 201所接收的辅载波的配置信息中, 还可 标识出该辅载波为非授权频谱或共享频谱, 当第一控制模块 202接收到所述 第一激活命令后, 便检测所述配置的辅载波是否被标识为非授权频谱或是共 享频谱, 如果是, 则激活所述配置的辅载波以得到激活辅载波并打开相应的 RF模块, 以为 UE与 eNB之间通过所述激活辅载波进行数据传输做准备。
时间确定模块 203 , 用于接收所述基站发送的所述激活辅载波的使用权 控制信息, 根据所述使用权控制信息确定所述激活辅载波的可用时间。
第二控制模块 204 , 用于在所述时间确定模块 203确定的可用时间内, 进行与所述激活辅载波相关的操作; 在到达所述时间确定模块 203确定的可 用时间后, 停止进行与所述激活辅载波相关的操作。
本实施例第一控制模块 202和第二控制模块 204中, 所述与所述激活辅 载波相关的操作包括: 与所述激活辅载波相关的物理层下行控制信道
(Phys ica l Downl ink Contro l Channel,筒称 PDCCH)检测和相关信息的上报, 以及接收基站利用所述激活辅载波发送的下行数据。 其中, 所述相关信息包 括信道质量指示 (Channel Qua l i ty Indi cator , 筒称 CQI )、 预编码矩阵索 引号 ( Precoding Matr ix Index , 筒称 ΡΜΙ ) 、 秩指示 ( Rank Indicator , 筒称 RI )和预编码类型指示 (Precoding Type Indicator , 筒称 PTI ) 中 的一个或多个; 所述与所述激活辅载波相关的 PDCCH检测包括: 在激活辅载 波上的 PDCCH检测、 以及利用其它载波对所述激活辅载波上的数据进行调度 时所述其它载波上的 PDCCH检测。
参见图 3 , 示出了激活辅载波可用时间示意图。 当所述激活辅载波为非 授权频谱时, UE需要与在非授权频谱上工作的 WiFi等其它通信设备共享使 用非授权频谱, 当所述激活辅载波为授权的共享频谱时, UE需要与在共享频 谱上工作的其它通信设备共享使用共享频谱, 所以, eNB 需要以竟争方式或 是非竟争方式得到所述激活辅载波的使用权, 且每次获取到所述使用权的时 间是有限的, 比如所述非授权频谱的可用时间大约在 10毫秒左右。基于所述 可用时间的非连续性, 当没有获取到所述激活辅载波的使用权时, 如果在第 一控制模块 202打开 RF模块的同时,进行与激活辅载波相关的 PDCCH检测并 反馈相关信息, 这样会消耗不必要的能耗在 PDCCH检测上, 以及消耗不必要 的资源来反馈相关信息, 所以, 本发明实施例中的第二控制模块 204只在激 活辅载波的可用时间内检测 PDCCH和反馈相关信息,这样可以节省 UE侧的能 耗和资源, 此外, 由于所述激活辅载波的可用时间较短, 这样也可以在有效 的时间内充分利用所述激活辅载波来进行数据传输, 进一步提高了载波资源 的利用效率。 在上述实施例中, 对于所述时间确定模块 203如何确定所述激活辅载波 的可用时间, 包括以下三种实现方式:
方式一:
由于所述激活辅载波的使用权在时间轴上是离散的, 基于此限制, 所述 第二控制模块 204可根据基站下发的第二激活命令和第二去激活命令, 使 UE 在这两个命令的时间间隔内 (即激活辅载波的可用时间)执行与激活辅载波 相关的操作。 具体实现如下:
当 eNB 具有或者即将具有所述激活辅载波的使用权时,可以利用主载波 或任一已经激活的辅载波向 UE发送第二激活命令, 使 UE进行与所述激活辅 载波相关的 PDCCH检测和相关信息的上报,以及通过所述激活辅载波实现 eNB 与 UE间的数据传输;当 eNB失去或即将失去所述激活辅载波的使用权时, eNB 可以通过向 UE发送第二去激活命令, 使 UE停止进行与所述激活辅载波相关 的 PDCCH检测和相关信息的上报,并不再通过激活辅载波实现 eNB与 UE间的 数据传输。
基于上述内容, 所述时间确定模块 203 , 具体包括:
第一信息接收子模块, 用于接收所述基站先后发送的第二激活命令和第 二去激活命令。 其中, 所述第二激活命令可以是所述基站在具有所述激活辅 载波的使用权时或具有所述激活辅载波的使用权前发送的命令, 所述第二去 激活命令可以是所述基站在失去所述激活辅载波的使用权时或失去所述激活 辅载波的使用权前发送的命令。
第一时间确定子模块, 用于将所述第一信息接收子模块接收所述第二激 活命令和所述第二去激活命令的间隔时间确定为所述激活辅载波的可用时 间。
方式二:
由于所述激活辅载波的使用权在时间轴上是离散的, 基于此限制, 所述 第二控制模块 204可根据基站下发的携带激活时间的第三激活命令,使 UE在 所述激活时间内(即激活辅载波的可用时间)执行与激活辅载波相关的操作。 具体实现如下:
当 eNB具有或者即将具有所述激活辅载波的使用权时, 可以利用主载波 或任一已经激活的辅载波向 UE发送携带激活时间的第三激活命令, 使 UE在 所述激活时间内进行与所述激活辅载波相关的 PDCCH 检测和相关信息的上 报,以及在所述激活时间内利用所述激活辅载波实现 eNB与 UE间的数据传输; 在到达所述激活时间后, 说明 eNB 已经失去了所述激活辅载波的使用权, 此 时 UE停止进行与所述激活辅载波相关的 PDCCH检测和相关信息的上报,并不 再通过激活辅载波实现 eNB与 UE间的数据传输。
基于上述内容, 所述时间确定模块 203 , 具体包括:
第二信息接收子模块, 用于接收所述基站发送的携带激活时间的第三激 活命令。 其中, 所述第三激活命令可以是所述基站在具有所述激活辅载波的 使用权时或具有所述激活辅载波的使用权前发送的命令。
第二时间确定子模块, 用于将所述激活时间确定为所述激活辅载波的可 用时间。
方式三:
由于所述激活辅载波的使用权在时间轴上是离散的, 基于此限制, 所述 第二控制模块 204可不断检测基站下发的同步信号,使 UE在能够接收同步信 号的期间 (即激活辅载波的可用时间)执行与激活辅载波相关的操作。 具体 实现如下:
当 eNB具有所述激活辅载波的使用权时, 可利用所述激活辅载波不断地 向 UE发送同步信号, 使 UE在能够检测到同步信号的期间内, 进行与所述激 活辅载波相关的 PDCCH检测和相关信息的上报, 并在此期间通过所述激活辅 载波实现 eNB与 UE间的数据传输; 当 eNB失去所述激活辅载波的使用权时, 便不再向 UE发送同步信号, 当 UE检测不到所述同步信号时, UE便停止进行 与所述激活辅载波相关的 PDCCH检测和相关信息的上报, 并不再通过激活辅 载波实现 eNB与 UE间的数据传输。
基于上述内容, 所述时间确定模块 203 , 具体包括:
第三信息接收子模块, 用于接收所述基站利用所述激活辅载波以设定频 率发送的同步信号。 其中, 所述同步信号是基站在具有所述激活辅载波的使 用权时发送的信号。
第三时间确定子模块, 用于将所述第三信息接收子模块能够接收到所述 同步信号的期间确定所述激活辅载波的可用时间。 进一步地, 当 UE侧的第一控制模块 202接收到第一激活命令后, 如果判 断得到该激活辅载波为非授权频谱或共享频谱,则此时不启动去激活定时器, 即, 将去激活定时器的时间设置为无穷大或使去激活定时器处于关闭状态。 待 UE接收到 eNB发送的第二激活命令或第三激活命令或同步信号以确定所述 激活辅载波可用后, 如果去激活定时器处于未启动状态, 则 UE启动去激活定 时器, 并根据预设的定时时间进行计时; 如果去激活定时器处于暂停状态, 则 UE继续进行该去激活定时器的计时,定时器的计时时间为上次暂停时的时 间。 而且在所述激活辅载波的可用时间内, UE可能会多次接收到 eNB发送的 下行数据, 则当每接收一次下行数据时, UE便重新启动一次去激活定时器, 并根据预设的定时时间进行计时。 在 UE的去激活定时器的计时过程中, 如果 去激活定时器超时, 则 UE去激活所述激活辅载波, 并停止进行与所述激活辅 载波相关的 PDCCH检测和相关信息的上报, 以及关闭所述 RF模块; 如果去激 活定时器没有出现计时超时的情况, 则在上述时间确定模块 203三种实现方 式的基础上, UE可根据 eNB的以下其中一种指示控制去激活定时器,具体为: 1 )、 当 UE接收到 eNB发送的第二去激活命令后, 则 UE暂停去激活定时 器并保持当前去激活定时器的计时时间;
2 )、 当 UE接收到 eNB发送的携带激活时间的第三去激活命令后, 待所述 激活时间计时超时,则 UE暂停去激活定时器并保持当前去激活定时器的计时 时间;
3 )、 当 UE在激活辅载波上无法检测到 eNB发送的同步信号时, 则 UE暂 停去激活定时器并保持当前去激活定时器的计时时间。
基于上述内容, 上述用户设备还包括:
定时器启动模块, 用于当所述时间确定模块 203接收到所述基站发送的 所述激活辅载波的使用权控制信息后, 如果自身的去激活定时器处于未启动 状态, 则启动所述去激活定时器, 以使所述去激活定时器按照预设的定时时 间进行计时, 如果自身的去激活定时器处于暂停状态, 则使所述去激活定时 器从暂停的时刻继续按照预设的定时时间进行计时;
定时器重启模块, 用于当所述第二控制模块 204每次接收到所述下行数 据时, 重启去激活定时器, 以使所述去激活定时器按照预设的定时时间重新 进行计时;
定时器暂停模块, 用于如果所述去激活定时器计时未超时且到达所述时 间确定模块 203确定的可用时间, 则暂停所述去激活定时器; 第三控制模块, 用于如果所述去激活定时器超时则去激活所述激活辅载 波, 并停止进行与所述激活辅载波相关的操作, 且关闭所述 RF模块。
进一步地, 在上述实施例中, 当基站不需要利用所述激活辅载波进行数 据传输时, 可通过下发第一去激活命令使用户设备停止一切与所述激活辅载 波相关的设置或操作, 因此, 所述用户设备还可以包括: 第四控制模块, 用 于在接收到所述基站发送的第一去激活命令后, 去激活所述激活辅载波, 并 停止进行与所述激活辅载波相关的操作, 且关闭所述 RF模块。
可以理解的是, 本发明实施例中的基站可以是采用长期演进(Long Term Evolut ion , LTE ) 或通用 移 动 通信 系 统 ( Universa l Mobi le Telecommuni cat ions Sys tem, UMTS )等任何技术的基站设备; 本发明实施例 中的激活命令可以是无线资源控制协议( Radio Resource Control ,筒称 RRC )、 或媒体访问控制 ( MediaAcces sControl , 筒称 MAC )、 或物理层 ( hys ica l layer , PHY )等协议层的信令。
