Description

工作状态的控制方法及终端设备 技术领域
本发明涉及一种通信领域, 特别涉及一种工作状态的控制方法及终 端设备。 背景技术
为了实现用户无处不在的网络接入, 终端设备需要安装多套收发机 以接入不同的网络。例如,终端设备可以同时安装有长期演进(LTE, Long Term Evolution)系统, 工业科学医学(ISM, Industrial Scientific Medical) 系统 (例如 WiFi、 蓝牙 BlueTooth等) 的收发机。 由于同一终端设备内 多套收发机距离非常近, 一个系统发射机的功率可能会远高于另外一个 系统接收机的功率。
图 1给出了一个干扰共存的示例,如图 1所示,终端设备可包括 LTE 系统、 GPS系统和蓝牙 /WiFi系统, LTE系统可能对蓝牙 /WiFi系统产生 干扰, 蓝牙 /WiFi系统也可能对 LTE系统产生干扰。如果不同系统的工作 频带间隔较远, 通过滤波技术可以很好的控制发射信号对接收信号造成 的干扰。
然而, 对于有些场景, 例如, 当同一终端设备内不同系统的工作频 段非常接近时, 目前的滤波技术不足以提供有效的干扰避免。 因此针对 这样的场景, 为了实现终端设备内多种系统收发机共存时的干扰避免, 除了滤波技术外, 还需要考虑其他的方法。
目前, 3GPP主要考虑了下述系统共存的场景。
(1) LTE和 WiFi系统共存
(2) LTE 和 Bluetooth系统共存
(3) LTE 和全球导航卫星系统 (GNSS , Global Navigation Satellite System) 共存
而在上述系统共存的场景中, 会出现的干扰问题包括:
(1)在 LTE 系统的 Band 40, LTE系统的信号发送会对 ISM系统的信 号接收造成干扰; (2)在 LTE系统的 Band 40, ISM系统的信号发送会对 LTE系统的信 号接收造成干扰;
(3)在 LTE系统的 Band 7, LTE系统的信号发送会对 ISM系统的信 号接收造成干扰;
(4)在 LTE系统的 Band 7/13/14, LTE系统的信号发送会对 GNSS系 统的信号接收造成干扰
为了避免上述场景下的共存干扰, 其中一种方法为采用时分复用的 方式, 将两个不同系统的信号发送和信号接收从时间上分开。 图 2 是终 端设备在不同时刻接收 LTE系统信号、以及发送 WiFi或蓝牙信号的实例 示意图。
目前, 3GPP定义了两种实现时分复用的方法。 包括:
(1) 基于自动重传请求 (HARQ)进程预留的方法。 该方法根据 LTE系 统定义的 HARQ 进程的时间关系, 为 LTE系统预留部分子帧, 而将其余 的子帧分配给 ISM系统, 即在其余的子帧, 设备终端可以进行 ISM系统 数据的发送和接收。
(2) 基于 LTE系统的非连续接收 (DRX)的方法。该方法利用目前 LTE 系统的 DRX机制,在终端设备的 LTE收发机进入休眠状态后, 终端设备 可以进行 ISM系统数据的发送和接收。
为了实现该方法, 终端设备需要向基站发送其希望的 LTE 系统和 ISM系统工作的周期、 以及在该周期内 LTE系统的工作时间和 ISM系统 的工作时间 (下文将其称为 TDM图样: ), 以及其他的一些辅助信息,例如, 干扰类型, 共存模式等。 而后由基站来最终确定 LTE系统和 ISM系统共 存的 TDM图样, 并通过适当的配置 DRX的参数来实现该 TDM图样。 图 3示例了一个终端设备向基站建议的 TDM图样。图 4示例了一个根据 该建议的 TDM图样, 基站最终决定的 DRX的配置。
但是, 在实现本发明的过程中, 发明人发现现有技术的缺陷在于: 在 LTE和 ISM共存的情况下,如果在终端设备结束 LTE时间并开始 ISM 时间之前, 终端设备发起了调度请求或随机接入过程; 而在终端设备结 束 LTE时间并开始 ISM时间时, 该调度请求 /随机接入过程还未完成。此 时终端设备进入 ISM工作状态,那么为了避免 LTE和 ISM系统间的相互 干扰, 需要停止尚未完成的调度请求和随机接入过程。 而在 ISM工作时 间结束后, 需要重新发起此过程。这样将会导致对 LTE系统资源的浪费, 影响 LTE系统的性能。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容

具体实施方式
参照附图, 通过下面的说明书, 本发明的前述以及其它特征将变得 明显。 在说明书和附图中, 具体公开了本发明的特定实施方式, 其表明 了其中可以采用本发明的原则的部分实施方式, 应了解的是, 本发明不 限于所描述的实施方式, 相反, 本发明包括落入所附权利要求的范围内 的全部修改、 变型以及等同物。
为了控制终端设备从 LTE工作状态转入 ISM工作状态, 根据 LTE 的 DRX机制, 目前给出了三种方法。 具体细节可以参见: (R2-106399, "Potential mechanism to realize TDM pattern",Huawei, HiSilicon)。
图 5是通过 LTE系统的 DRX机制的开启时间 (On duration) 控制 终端设备从 LTE工作状态转入 ISM工作状态的示意图。 如图 5所示, 在 On duration结束后, 终端设备停止 LTE工作状态, 进入 ISM工作状态。 图 6是通过去激活定时器(Inactivity timer)控制终端设备从 LTE工 作状态转入 ISM工作状态的示意图。 如图 6所示, 在 Inactivity timer超 时后, 终端设备停止 LTE工作状态, 进入 ISM工作状态。
如图 6 所示, 终端设备在接收到基站发送的物理下行控制信道 (PDCCH, Physical Downlink Control Channel)资源之后, 可以启动或重 新启动 Inactivity timer,在 Inactivity timer未超时时,终端设备不转入 ISM 状态。
图 7是通过非连续接收命令(DRX Command)控制终端设备从 LTE 工作状态转入 ISM工作状态的示意图。 如图 7所示, 终端设备通过接收 到的 DRX Command进行控制, 即基站发送 DRX Command控制终端设 备从 LTE工作状态转入 ISM工作状态。
然而,在上述方法中存在如下的问题:在 On duration结束且 Inactivity timer超时、 或者收到 DRX Command后, 终端设备立即进入 ISM工作状 态, 由此可能需要停止尚未完成的调度请求或随机接入过程,导致对 LTE 系统资源的浪费。
本发明实施例提供一种工作状态的控制方法, 如图 8所示, 所述方 法包括:
歩骤 801, 终端设备在 On duration结束且去激活定时器超时、 或者 接收到基站发送的非连续接收命令时, 判断向基站发起的调度请求过程 或随机接入过程是否完成;
歩骤 802, 在歩骤 801 判断调度请求过程或随机接入过程没有完成 时, 终端设备不转入 ISM工作状态而保持在 LTE工作状态。
在一个实施例中, 在歩骤 801 之前, 终端设备已经在物理上行控制 信道(PUCCH, Physical Uplink Control Channel)上发送了调度请求, 歩 骤 801可以具体判断调度请求过程是否完成。
图 9是本发明实施例的工作状态的控制方法的又一流程图, 如图 9 所示, 该方法包括:
歩骤 900, 终端设备在物理上行控制信道上发送调度请求。
如图 9所示, 终端设备在 On duration结束且去激活定时器超时、 或 者接收到基站发送的非连续接收命令时, 进行如下歩骤: 歩骤 901,终端设备判断发送的调度请求是否取消,若调度请求没有 取消, 则执行歩骤 902; 若调度请求已经取消, 则执行歩骤 904。
歩骤 902, 确定调度请求过程没有完成。
歩骤 903, 终端设备不转入 ISM工作状态而保持在 LTE工作状态。 歩骤 904, 确定调度请求过程完成。
歩骤 905, 终端设备转入 ISM工作状态。
如图 9所示, 在歩骤 903之后, 该方法还可以包括:
歩骤 906, 终端设备监听物理下行控制信道 (PDCCH , Phsical Downlink Control Channel ) ; 并判断调度请求禁止计时器 ( SR-prohibit timer) 是否超时;
在本实施例中, 如果在 SR-prohibit timer超时前, 终端设备接收到基 站根据该调度请求在物理下行控制信道 (PDCCH , Phsical Downlink Control Channel) 上发送的上行资源; 该方法还可以包括:
歩骤 907, 终端设备开启去激活定时器(Inactivity timer) , 使得去激 活定时器重新开始计时。
在去激活定时器重新开始计时之后、 超时之前, 该终端设备仍然可 以工作在 LTE工作状态。 在去激活定时器超时之后, 终端设备转入 ISM 工作状态。
在本实施例中, 如果直到 SR-prohibit timer计时超时, 终端设备仍没 有接收到基站根据该调度请求在物理下行控制信道发送的上行资源; 则 该方法还可以包括:
歩骤 908,终端设备判断该调度请求过程失败,终端设备可以自己决 定是否重新发起调度过程。
在本实施例中, 如果终端设备决定停止继续发送调度过程, 那么终 端设备可以转入 ISM系统工作状态; 如果终端设备决定重新发起调度过 程, 那么终端设备可以在物理上行控制信道上发送调度请求, 并继续保 持在 LTE工作状态, 监听物理下行控制信道。
在另一个实施例中, 在歩骤 801 之前, 终端设备已经在物理随机接 入信道 (PRACH, Physical Random Access Channel) 上发送了前导信息 (Preamble) , 歩骤 801可以具体判断随机接入过程是否完成。 图 10是本发明实施例的工作状态的控制方法的又一流程图,如图 10 所示, 该方法包括:
歩骤 1000, 终端设备在物理随机接入信道上发送前导信息。
如图 10所示, 终端设备在 On duration结束且去激活定时器超时、 或者接收到基站发送的非连续接收命令时, 进行如下歩骤:
歩骤 1001, 终端设备判断是否接收到随机接入响应消息; 若没有接 收到随机接入响应消息、 且随机接入响应窗口还未超时, 则执行歩骤
1002。
歩骤 1002, 终端设备确定随机接入过程没有完成。
歩骤 1003, 终端设备不转入 ISM工作状态而保持在 LTE工作状态。 在本实施例中, 如图 10所示, 如果随机接入响应窗口超时, 则该方 法还可以包括:
歩骤 1004, 终端设备判断随机接入过程失败, 并且决定是否重新发 起随机接入过程。
在本实施例中, 如果终端设备决定重新发起随机接入过程, 那么在 退避时间结束后, 终端设备在物理随机接入信道上发送前导信息并继续 保持在 LTE工作状态; 如果终端设备决定停止继续发起随机接入过程, 那么终端设备直接转入 ISM工作状态。
如图 10所示, 在歩骤 1001判断接收到随机接入响应消息, 该方法 还可以包括:
歩骤 1005,判断该随机接入响应消息是否包含该前导信息的识别符; 在该随机接入响应消息包含该前导信息的识别符时, 执行歩骤 1006; 否 则执行歩骤 1004。
如图 10所示, 在接收到随机接入响应消息、 且该随机接入响应消息 包含该前导信息的识别符时, 该方法还可以包括:
歩骤 1006, 终端设备判断是否发送了第一次调度传输的数据, 即 Message 3; 若没有发送第一次调度传输的数据, 则执行歩骤 1002, 确定 随机接入过程没有完成。
如图 10所示, 在歩骤 1006判断发送了第一次调度传输的数据时, 该方法还可以包括: 歩骤 1007, 终端设备判断是否接收到竞争解决消息; 若没有接收到 竞争解决消息、 且用于控制竞争解决消息接收的计时器没有超时, 则执 行歩骤 1002, 确定随机接入过程没有完成; 若接收到竞争解决消息, 可 以执行歩骤 1008。
歩骤 1008, 确定随机接入过程完成。
歩骤 1009, 终端设备转入 ISM工作状态。
在本实施例中, 如图 10所示, 如果用于控制竞争解决消息接收的计 时器超时, 则终端设备可以执行歩骤 1004, 判断随机接入过程失败, 并 且决定是否重新发起随机接入过程。
如果终端设备决定重新发起随机接入过程,那么在退避时间结束后, 终端设备在物理随机接入信道上发送前导信息并继续保持在 LTE工作状 态; 如果终端决定停止继续发起随机接入过程, 那么终端设备直接转入 ISM工作状态。
由上述实施例可知, 通过终端设备在 on duration结束且去激活定时 器超时、 或者接收到基站发送的非连续接收命令时, 判断调度请求过程 或随机接入过程是否完成; 在没有完成时不转入 ISM工作状态而保持在 LTE工作状态;可以降低对 LTE系统资源的浪费,提高 LTE系统的性能。

并且, 过程确定器 1302还用于在第三判断器 1304没有接收到竞争 解决消息、 且用于控制竞争解决消息的计时器没有超时, 确定随机接入 过程没有完成。
在一个实施例中, 终端设备还可以包括: 第二失败判断器 (图中未 示出); 第二失败判断器用于在直到随机接入响应窗口超时仍未收到随机 接入响应消息、 或者接收到的随机接入响应消息中不包含终端设备在物 理随机接入信道上发送的前导信息的识别符、 或者用于控制竞争解决消 息的计时器超时时, 判断随机接入过程失败, 并决定是否继续重新发起 随机接入过程。
