S110、 UE可以判断正在工作的第一系统与第二系统是否存在干扰。 如果判断结果 为存在干扰， 执行 S120。 可选的， 如果第二系统开始被使用或者第二系统需要被使用 （此时第二系统尚未开 始被使用）， 则 UE进行 S110的判断。例如， 第一系统为 LTE系统， UE接收到的通过 GPS 系统进行定位的命令， 说明 GPS系统需要被使用， 则 UE判断 LTE系统与 GPS系统是否会 发生干扰。又如， 第一系统为无线局域网（Wireless Local Area Network, WLAN)系统， UE开始使用 LTE系统时， UE判断 WLAN系统和 LTE系统是否会发生干扰。 可选的， UE通过比较 LTE系统的工作频段和第二系统使用的频段是否邻近， 例如频 段相距是否小于等于门限值 （如 100MHz) ， 来判断 LTE系统与第二系统是否存在干扰。 如果邻近， 则判断结果第一系统与第二系统会发生干扰。 这种情况下的第一系统与第二 系统可称为对方的干扰系统。 例如， LTE系统的 band 13和 band 14的谐波都邻近 GPS系统使用的频段， 因此， 可简 称为 LTE band 13为 GPS系统的干扰系统， LTE band 14为 GPS系统的干扰系统， 或者， GPS系统为被 LTE band 13或 LTE band 14干扰的系统， 简称被干扰系统。又如， LTE系统 的 band 40邻近ISM系统中WLAN系统使用的频段， 还邻近 ISM系统中蓝牙 （BlueTooth, BT)使用的频段，因此，可简称为 LTE band 40与 ISM WLAN系统互为干扰系统， LTE band 40与 ISM BT互为干扰系统。 本实施例以 LTE band 13为 GPS系统的干扰系统为例进行说明， 本实施例还适用于 LTE band 14为 GPS系统的干扰系统的情况， 不再单独描述。 S120、 UE将判断结果通知给基站。 其中， UE可以将判断结果通知给 LTE系统中正在为 UE提供服务的基站。 可选的， UE通过发送表示存在干扰的第一指示给基站。 例如， 该第一指示占用 1比 特信息， 该比特信息为 1时， 表示存在干扰； 该比特信息为 0时， 表示不存在干扰。 由于 各区域中如何划分和应用频谱是比较稳定的， 对于基站来说， LTE系统的当前工作频段 也是可知的， 因此， 如果接收到表示存在干扰的第一指示， 基站能够确定是对 LTE系统 的当前工作频段产生干扰的频段，还可以进而根据频段与系统的对应关系来确定哪个系 统为干扰系统。例如， LTE的工作频段为 band 13或 band 14，也即 UE工作在 band 13或 band 14上， 则基站接收到表示存在干扰的第一指示时， 可以确定被干扰系统为 GPS系统。 可选的， 第一指示携带在 UE发送给基站的无线资源控制 （Radio Resource Control, RRC) 消息中。 例如占用现有的用户设备信息响应 （UEInformationResponse) 消息的备 用字段或扩展字段或通过新增 RRC消息实现。
S130、 UE将被干扰系统 （即 GPS系统） 的调度信息发送给上述基站。 本步骤中的调度信息可以与 S120中 UE发送的第一指示携带在同一消息中 （则本步 骤与 S120同时被实现） ， 也可以携带在 S120之前或之后 UE发送给基站的消息中， 例如 RRC消息。 干扰系统为基于调度的 GPS系统时， UE可以获取到该系统发送的调度信息。 例如， GPS系统采用 C/A码作为测距码。 如图 2所示， GPS系统的 C/A码， 起始接收时间为 A， C/A码接收间隔为 10ms (如图 2所示 GPS系统时间轴上的细线） ， C/A码持续接收时间为 10ms (如图 2所示 GPS系统时间轴上的粗线） ， LTE系统中 1帧包含 10子帧， 每个子帧的 时长为 lms。可选的， GPS系统与 LTE (如 band 13 )系统的时间基准不同时， UE将以 GPS 系统的时间 （即测距码形式） 为基准的调度信息转换为以 LTE系统的时间 （即帧和子帧 形式） 为基准的调度信息， 以使 LTE系统的基站能够读懂 GPS系统的调度信息。 如图 2 所示， UE可以将 GPS系统的 C/A码起始接收时间转换成 LTE系统的时间， 例如 GPS系统 的时间 A对应 LTE系统中的编号为 12的帧中第 2个子帧， C/A码接收间隔为 10ms以及 C/A 码持续接收时间为 10ms转换为 LTE系统中接收周期为 20ms，每个周期内持续接收时间为 10ms (如图 2所示 LTE时间轴上的粗线） 。 也就是， UE发送给 LTE系统中的基站的调度 信息为： 20 (接收周期， 单位为 ms或子帧） ， 12和 2 (起始接收时间的无线帧号 SFN和 子帧号）， 10 (每个周期内持续接收时间， 单位为 ms或子帧）。可选的， GPS系统与 LTE (如 band 13 ) 系统的时间基准不同时， UE将以 GPS系统的时间为基准的调度信息转换 为以绝对时间为基准的调度信息， 以使 LTE系统的基站能够读懂 GPS系统的调度信息。 可选的， GPS系统的调度信息是以绝对时间为基准的调度信息时， UE将 GPS系统的调度 信息直接发送给 LTE系统的基站， 从而减少 UE的操作， 或者， 将以绝对时间为基准的调 度信息转换为以 LTE系统的时间为基准的调度信息，从而减少基站接收 UE发送的调度信 息所需的操作。 上述绝对时间也可称为公共时间， 是各系统共用的时间基准， 例如采用 年月日和时分秒的形式。 可选的， 采用哪种时间为基准在系统标准中规定。
S140、 基站生成临时调度信息， 并将该临时调度信息发送给 UE， 该临时调度信息 所指示的基站对 UE进行的调度与 GPS系统对 UE的调度不冲突。 可选的， 该临时调度信息携带在基站发送给 UE的 RRC消息中。 可选的， 临时调度信息指示基站在哪些时刻对 UE不进行调度， 以便 UE在该时刻使 用其它系统。 例如， 临时调度信息包括调度周期、 一个调度周期内基站不调度 UE的起 始时间 （可简称为停止调度 UE的起始时间） 和一个调度周期内基站不调度 UE的持续时 间 （可简称为停止调度 UE的持续时间） 。 在一个调度周期内， 基站在停止调取 UE的持 续时间之外的时间内， 可以调度 UE。 又如， 临时调度信息包括调度周期、 一个调度周 期内基站不调度 UE的起始时间 （可简称为停止调度 UE的起始时间） 和一个调度周期内 基站不调度 UE的结束时间 （可简称为停止调度 UE的结束时间） 。 可选的， 临时调度信息不直接指示基站在哪些时刻对 UE不进行调度， 而是指示基 站在哪些时刻对 UE进行调度， 也能够起到便于 UE确定调度周期内基站在哪些时刻不对 UE进行调度， 并在该时刻使用其它系统。 例如， 临时调度信息包括调度周期、 一个调 度周期内基站调度 UE的起始时间和一个调度周期内基站调度 UE的持续时间。 又如， 临 时调度信息包括调度周期、 一个调度周期内基站调度 UE的起始时间和结束时间。 需要说明的是， 无论基站向 UE指示的是调度 UE的时刻还是不调度 UE的时刻， 都能 够起到相同作用的原因在于： 一个调度周期可以划分为基站可能或者说被允许调度 UE 的时段 （简称第一时段） 和基站不可能或者说被禁止调度 UE的时段 （简称第二时段） 。 因此， 只要基站能够指示出第一时段的起始时间、 结束时间和持续时间中的任两项， 或 者第二时段的起始时间、 结束时间和持续时间中的任两项， UE都能够分辨出基站何时 不会调度 UE (即第二时段） ， 何时可能调度 UE (即第一时段） 。 因此， 本发明各实施 例虽然主要以临时调度信息包括调度周期、 一个调度周期内基站停止调度 UE的起始时 间和一个调度周期内基站停止调度 UE的持续时间进行举例， 但不意味着仅限定于此。 基站根据接收的第一指示和 UE发送的调度信息， 可以获知 GPS系统为被干扰系统， 以及 GPS系统将如何调度 UE， 当然， 基站也可以认为 UE发送的调度信息是 UE建议如何 接收来自 GPS系统的数据。可选的， 基站通过修改 UE发送的调度信息来实现生成临时调 度信息， 例如， 基站根据 UE的当前业务情况和 /或该基站的当前资源调度情况修改 UE发 送的调度信息， 再将修改后的调度信息作为临时调度信息发送给 UE。 需要说明的是， 本发明各实施例采用 "A和 /或 B"的方便描述， 包括以下三种情况： （1 ) A; (2) B; 或 (3 ) A禾口 B。 例如， UE的当前业务情况为使用 VoIP业务， 基站对该 UE进行半静态调度， 假设每 20ms为一个周期， UE在每个周期内的特定子帧接收或发送一次 VoIP业务数据， 该特定 子帧与 UE根据 GPS系统的调度信息可以接收来自 GPS系统的数据的时段（起始接收时间 SFN为 12的帧中第 2个子帧， 持续接收时间为 10ms) 相重叠， 即基站对 UE进行的调度与 GPS系统对 UE的调度发生冲突： 如果按照基站当前对 UE的半静态调度, UE应该在该特 定子帧对应到 LTE系统的某时刻发送或接收 LTE系统数据； 如果按照 UE发送的 GPS系统 的调度信息， UE应该在该特定子帧接收来自 GPS系统的数据， 而不能发送或接收 LTE数 据。 因此， 基站需要对 UE发送的调度信息进行修改， 或者， 对正在对 UE进行的半静态 调度进行重配置。例如：基站将 UE发送的调度信息中停止调度 UE的起始时间" SFN为 12" 修改为 "SFN为 13"， 即基站将对 UE进行的临时调度包括： 从 SFN为 13的帧中的第 2个子 帧开始， 持续 10个子帧 （即 10ms) 不调度 UE， 调度周期为 20ms (相当于两次不调度 UE 的时段之间的时间间隔为 10ms) ， 从而将基站对 UE的半静态调度错开 GPS系统对 UE的 调度。 进一步的， 基站发送给 UE的临时调度信息可以为 20 (调度周期， 单位为 ms或子 帧） ， 13和 2 (停止调度 UE的起始时间的 SFN和子帧号） ， 10 (每个周期内不调度 UE的 持续时间，单位为 ms或子帧）。基站给 UE发送的调度信息中可能调度 UE的起始时间" SFN 为 12"， 即基站将对 UE进行的临时调度包括： 从 SFN为 12的帧中的第 2个子帧开始， 持续 10个子帧（即 10ms)可能调度 UE， 调度周期为 20ms (相当于两次可能调度 UE的时段之 间的时间间隔为 10ms) ， 从而将基站对 UE的半静态调度错开 GPS系统对 UE的调度。 进 一步的， 基站发送给 UE的临时调度信息可以为 20 (调度周期， 单位为 ms或子帧） ， 12 和 2 (可能调度 UE的起始时间的 SFN和子帧号） ， 10 (每个周期内可能调度 UE的持续时 间， 单位为 ms或子帧） 。 又如， 基站当前对其控制的其他 UE的资源调度情况为基站正在对其他某些 UE进行 的临时调度 （例如， 因存在系统间的干扰而按照某临时调度信息调度这些 UE) 与 UE发 送给基站的 GPS系统对 UE的调度一致。如果基站不进行调整， 可能导致基站在某段时间 不调度任何 UE或者可调度的 UE明显减少，则这段时间的资源没有被利用或利用率很低， 出现资源浪费。 因此， 基站可以对不同 UE的临时调度在时间上错开， 例如， 基站为不 同 UE生成的临时调度信息中， 停止调度 UE的起始时间各不相同， 从而避免资源浪费， 将小区资源利用率最大化。 又如， 基站先根据 UE的当前业务情况修改 UE发送的调度信息（简称第一次修改）， 然后根据该基站的当前资源调度情况再次修改（简称第二修改）第一次修改后的调度信 息， 并将第二次修改后的调度信息作为临时调度信息发送给 UE。 S150、 基站按照临时调度信息调度 UE。 对于 UE来说， 在临时调度信息指示的基站不调度 UE的时段， 可以接收 GPS系统的 数据。 例如， UE从 SFN为 13的帧中的第 2个子帧开始， 持续 10个子帧接收 GPS系统的数 据， 比如接收 GPS系统的 C/A码、 或 P码等测距码， 接收 GPS系统的导航电文等。 UE接收 GPS系统的数据以 20ms为一个周期。 可选的， 如果 GPS系统被关闭或停止使用， UE可以发送表示不存在干扰的第一指示 给基站 （S160) ， 则基站可以停止使用临时调度信息， 并通知 UE临时调度信息失效 ( S170) 。 例如， 基站改为采用现有技术调度 UE， 而不再受到其他系统调度 UE的影响。 可选的， 本实施例中的基站为 LTE系统中正在为 UE提供服务的基站， 如果 UE将从 该基站切换到目标基站，则该基站可以将 UE发送的第一指示和 GPS系统的调度信息发送 给目标基站， 以便于目标基站获知存在干扰系统， 并可能为该 UE生成临时调度信息。 本实施例中， LTE系统中的基站根据 UE发送的信息来生成临时调度信息， 可以避免 LTE系统和其他频段邻近的系统 （如 GPS系统） 对 UE的调度发生冲突， 解决 UE在两个 频段邻近的系统中收发消息相互干扰的问题。 如图 3所示， 本发明的另一个实施例提供一种方法。 该方法包括如下步骤。
S310、 与 S110类似。 区别在于， 本实施例将以 LTE bancHO与 ISM WLAN系统互为 干扰系统为例进行说明，本实施例还适用于 LTE band 40与 ISM BT互为干扰系统的情况， 不再单独描述。 S320、 与 S120类似。 区别在于， LTE band 40与 ISM系统互为干扰系统的情况包括：
LTE band 40与 ISM WLAN系统互为干扰系统， LTE band 40与 ISM BT互为干扰系统两种 情况。 因此， 如果 UE判断出 ISM WLAN系统或 ISM BT与 LTE band 40存在干扰， 则 UE 在本步骤中， 可以除发送第一指示外， 还发送第二指示给基站， 该第二指示用于表示与 LTE系统存在干扰的是 ISM WLAN系统还是 ISM BT。例如， 该第二指示占用 1比特信息， 该比特信息为 1时， 表示干扰系统为 ISM WLAN系统； 该比特信息为 0时， 表示干扰系统 为 ISM BT。 可选的， 第二指示与第一指示携带在相同的消息中， 以减少对空口资源的占用。
S330、 基站生成临时调度信息， 并将该临时调度信息发送给 UE， 该临时调度信息 指示基站在哪些时刻对 UE不进行的调度， 以便 UE在该时刻使用其它系统。 例如， 临时 调度信息包括调度周期、 一个调度周期内基站不调度 UE的起始时间 （可简称为停止调 度 UE的起始时间）和一个调度周期内基站不调度 UE的持续时间 （可简称为停止调度 UE 的持续时间） 。 又如， 临时调度信息包括调度周期、 一个调度周期内基站不调度 UE的 起始时间 （可简称为停止调度 UE的起始时间） 和一个调度周期内基站不调度 UE的结束 时间 （可简称为停止调度 UE的结束时间） 。 又如， 临时调度信息包括调度周期、 一个 调度周期内基站调度 UE的起始时间和一个调度周期内基站调度 UE的持续时间。 又如， 临时调度信息包括调度周期、 一个调度周期内基站调度 UE的起始时间和结束时间。 可选的， 该临时调度信息携带在基站发送给 UE的 RRC消息中。 干扰系统为基于竞争的 ISM WLAN系统时， 不存在该系统的调度信息。可选的， UE 可能生成建议调度信息并发送给基站， 该建议调度信息指示 UE期望基站如何调度 UE， 以使 UE能够在没有基站调度的时段内使用 ISM WLAN系统， 即与 ISM WLAN系统进行 通信， 包括上行或下行数据的传输、 信令交互等。 可选的， UE根据该 UE的 LTE系统业 务使用情况和其它系统业务使用情况生成建议调度信息， 建议基站允许该 UE接收来自 ISM WLAN系统的数据的时段。例如， UE在使用 WLAN系统进行 IP网络电话（例如 skype) 电话， 并使用 LTE系统进行数据下载， 为了尽量保证 IP网络电话电话的质量， 即尽量能 够周期性的发送接收 IP网络电话数据， UE可建议基站周期性的不调度 UE， 从而使 UE在 基站不调度 UE的时刻使用 WLAN系统的 IP网络电话电话业务。 例如， UE建议基站所做 的调度为： 基站从 SFN为 15的帧中的第 6个子帧开始， 持续 5个子帧（SP5ms)不调度 UE， 调度周期为 100ms (相当于两次不调度 UE的时段之间的时间间隔为 50ms) 。 进一步的， UE发送给基站的建议调度信息可以为： 100 (调度周期， 单位为 ms或子帧）， 15和 6 (停 止调度 UE的起始时间的 SFN和子帧号） ， 5 (每个周期内不调度 UE的持续时间， 单位为 ms或子巾贞） 。 如果 UE发送建议调度信息给基站， 则基站根据接收的第一指示、 第二指示和建议 调度信息， 可以获知 ISM WLAN系统为干扰系统， 并获知 UE建议基站如何调度 UE。 可 选的， 基站通过修改 UE发送的调度信息来实现生成临时调度信息， 例如， 基站根据 UE 的当前业务情况和 /或该基站的资源调度情况修改 UE发送的建议调度信息， 再将修改后 的调度信息作为临时调度信息发送给 UE。 例如， UE的当前业务情况为使用 VoIP业务， 基站对该 UE进行半静态调度， 假设每 20ms为一个周期， UE在每个周期内的特定子帧接收或发送一次 VoIP业务数据， 该特定 子帧与 UE建议接收来自 ISM WLAN系统的数据的时段（起始接收时间 SFN为 15的帧中第 6个子帧， 持续接收时间为 5ms) 相重叠， 因此， 基站需要对 UE发送的建议调度信息进 行修改， 或者， 对正在对 UE进行的半静态调度进行重配置。 例如： 基站将 UE建议的停 止调度 UE的起始时间" SFN为 15"修改为 "SFN为 16"， 即基站将对 UE进行的临时调度包 括： 从 SFN为 16的帧中的第 6个子帧开始， 持续 5个子帧 （SP5ms) 不调度 UE， 调度周期 为 100ms (相当于两次不调度 UE的时段之间的时间间隔为 50ms) ， 从而将基站对 UE的 半静态调度错开 UE接收来自 ISM WLAN系统的数据的时段。 进一步的， 基站发送给 UE 的临时调度信息可以为 100 (调度周期， 单位为 ms或子帧） ， 16和 6 (停止调度 UE的起 始时间的 SFN和子帧号） ， 5 (每个周期内不调度 UE的持续时间， 单位为 ms或子帧） 。 又如， 基站当前的资源调度情况为基站正在对其他某些 UE进行临时调度 （例如， 因存在系统间的干扰而按照某临时调度信息调度这些 UE) 与 UE发送给基站的建议调度 信息一致。 如果基站不进行调整， 可能导致基站在某段时间不调度任何 UE或者可调度 的 UE明显减少， 则这段时间的资源没有被利用或利用率很低， 出现资源浪费。 假设本 实施例中的 UE为 UE11 ,基站正在对其他 10个 UE (即 UE1至 UE10)进行临时调度，其中， 基站对 UE 1的临时调度为： 停止调度 UE 1的起始时间为 SFN为 1的帧中第 6个子帧， 持续 时间为 5ms, 调度周期为 30ms。基站对 UE 2的临时调度为：停止调度 UE 2的起始时间 SFN 为 31的帧中第 6个子帧， 持续时间为 5ms， 调度周期为 30ms， ...， 基站对 UE 10的临时调 度为： 停止调度 UE 10的起始时间为 SFN为 271的帧中第 6个子帧， 持续时间为 5ms， 调度 周期为 30ms。 如果其余的 UE都建议接收来自 ISM WLAN系统的数据的时段为： 起始接 收时间为 SFN为 31的帧中第 6个子帧， 持续接收时间为 5ms， 周期为 30ms， 也即 UE建议 基站在该时段内不要调度 UE， 则会存在同一个位置有多个 UE都无法被调度的情况。 基 站为了避免资源浪费， 例如避免 SFN为 31的第 6个子帧， 及其后续的 5ms不被任何 UE使 用而造成该资源浪费， 基站可以对其余的 UE进行离散分配。 例如， UE 11进行如下临时 调度： 基站从 SFN为 301的帧中的第 6个子帧开始， 持续 5个子帧（SP5ms)不调度 UE 11， 调度周期为 30ms， 相应的， 基站修改 UE发送的建议调度信息， 生成的临时调度信息为： 30 (调度周期， 单位为 ms或子帧）， 301和 6 (停止调度 UE的起始时间的 SFN和子帧号）， 5 (每个周期内不调度 UE的持续时间， 单位为 ms或子帧） 。 可选的， 如果 UE没有生成或发送建议调度信息给基站， 则基站根据接收的第一指 示和第二指示获知 ISM WLAN系统为干扰系统后， 可以生成临时调度信息。 例如， 根据 UE的当前业务情况和 /或该基站的资源调度情况为 UE生成临时调度信息。 例如， UE的当前业务情况为使用 VoIP业务， 基站对该 UE进行半静态调度， 假设每
20ms为一个周期， UE在每个周期内的特定子帧接收或发送一次 VoIP业务数据。 基站会 考虑尽可能避免对该半静态调度周期造成影响， 因此基站尽可能将临时调度周期避开该 半静态调度周期。 例如： 当前的半静态调度周期的起始时间 SFN为 15的帧中第 2个子帧， 周期为 20ms, 允许 UE收发数据的持续时间为 lms。 基站可以对 UE进行的临时调度包括： 从 SFN为 16的帧中的第 6个子帧开始， 持续 5个子帧 （SP5ms) 不调度 UE， 调度周期为 100ms, 相当于两次不调度 UE的时段之间的时间间隔为 50ms， 从而将基站对 UE的临时 调度错开当前对 UE进行的半静态调度。 进一步的， 基站发送给 UE的临时调度信息可以 为 100 (调度周期， 单位为 ms或子帧） ， 16和 6 (停止调度 UE的起始时间的 SFN和子帧 号） ， 5 (每次不调度 UE的持续时间， 单位为 ms或子帧） 。 又如， 基站当前的资源调度情况为基站正在对其他某些 UE进行临时调度， 假设本 实施例中的 UE为 UE11 ,基站正在对其他 10个 UE (即 UE1至 UE10)进行临时调度，其中， 基站对 UE 1的临时调度为： 停止调度 UE 1的起始时间为 SFN为 1的帧中第 6个子帧， 持续 时间为 5ms, 调度周期为 30ms。基站对 UE 2的临时调度为：停止调度 UE 2的起始时间 SFN 为 2的帧中第 6个子帧， 持续时间为 5ms， 调度周期为 30ms， ...， 基站对 UE 10的临时调 度为： 停止调度 UE N的起始时间为 SFN为 271的帧中第 6个子帧， 持续时间为 5ms, 调度 周期为 30ms。 如果还有其它 UE存在同样的干扰,如果基站重复分配 UE同一个临时调度， 必然会产生某个临时调度周期只有少量 UE可以被调度的情况， 则基站为了避免资源浪 费， 例如避免 SFN为 271的第 6个子帧， 及其后续的 5ms被重复分配， 以致于不被任何 UE 使用而造成该资源浪费， 基站可以对其余的 UE进行离散分配.例如 UE 11进行如下临时 调度： 基站从 SFN为 301的帧中的第 6个子帧开始， 持续 5个子帧（SP5ms)不调度 UE 11， 调度周期为 30ms， 相应的， 基站生成的临时调度信息为： 30 (调度周期， 单位为 ms或 子帧） ， 11和 6 (停止调度 UE的起始时间的 SFN和子帧号） ， 5 (每个周期内不调度 UE 的持续时间， 单位为 ms或子帧） 。 又如， 基站要对 UE进行的临时调度为： 基站从 SFN为 12的帧中的第 2个子帧开始， 持续 5个子帧 （SP5ms) 不调度 UE， 调度周期为 100ms (相当于两次不调度 UE的时段之 间的间隔为 50ms) 。 又如， 临时调度信息为 100 (调度周期， 单位为 ms或子帧） ， 12和 8 (停止调度 UE的起始时间的 SFN和子帧号） ， 5 (每个周期内不调度 UE的持续时间， 单位为 ms或子帧） 。 又如， UE的当前业务情况为未使用半静态调度接收业务， 基站的资源调度情况为 该基站下的其他 UE未进行临时调度， 则基站可以优先采用该 UE发送的建议调度信息。 如果基站没有接收到建议调度信息， 可以随机生成临时调度信息， 并通知 UE在临时调 度信息指示的基站不调度 UE期间， 发送或接收其他系统的数据。 又如， 基站先根据 UE的当前业务情况修改 UE发送的调度信息（简称第一次修改）， 然后根据该基站的当前资源调度情况再次修改（简称第二修改）第一次修改后的调度信 息， 并将第二次修改后的调度信息作为临时调度信息发送给 UE。
S340、 基站按照临时调度信息调度 UE。 对于 UE来说， 在临时调度信息指示的基站不调度 UE的时段， 可以与 ISM WLAN系 统进行上行或下行的通信， 包括数据上传和下载、 信令交互等。 可选的， 如果 ISM WLAN系统被关闭， UE可以发送表示不存在干扰的第一指示给 基站（S350) ,则基站可以停止使用临时调度信息，并通知 UE临时调度信息失效（S360)。 例如， 基站改为采用现有技术调度 UE， 而不再受到其他系统调度 UE的影响。 可选的， 本实施例中的基站为 LTE系统中正在为 UE提供服务的基站， 如果 UE将从 该基站切换到目标基站， 则该基站可以将 UE发送的第一指示和第二指示发送给目标基 站， 以便于目标基站获知存在干扰系统， 并可能为该 UE生成临时调度信息。 本实施例中， LTE系统中的基站根据 UE发送的信息来生成临时调度信息， 可以避免 LTE系统对 UE的调度和 UE使用其他频段相邻的系统 （如 ISM系统） 发生冲突， 解决 UE 在两个频段邻近的系统中收发消息相互干扰的问题。 本发明的另一个实施例提供一种方法， 该方法与如图 3所示的实施例所提供的方法 的区别在于， UE生成建议调度信息并发送给基站， 基站发送确认消息给 UE， 以确认建 议调度信息被接受， 然后基站按照建议调度信息调度 UE。 也就是说， 基站接受 UE对于 基站如何调度 UE的建议而无需生成临时调度信息， 也可以认为基站将 UE发送的建议调 度信息作为临时调度信息。 可选的， 基站发送给 UE的关于建议调度信息的确认消息可 以是 ACK消息， 或者包含确认字段的其他消息， 上述确认消息可以同时确认第一指示和 建议调度信息的正确接收。 本实施例可以避免 UE在两个频段邻近的系统中收发消息相互干扰，还可以减少 LTE 系统中的基站的内部操作， 例如生成临时调度信息的操作， 并有利于 UE协调对不同系 统的使用。 如图 4所示， 本发明的另一个实施例提供一种装置 40， 该装置 40可以用于实现本发 明其他实施例提供的调度方法中基站完成的动作。 例如， 该装置 40位于第一系统中， 并 包括接收单元 410、 处理单元 420和发送单元 430。 其中， 接收单元 410用于接收 UE发送 的第一指示， 所述第一指示表示第一系统与第二系统间存在干扰。 处理单元 420用于生 成临时调度信息， 并按照临时调度信息调度 UE。 发送单元 430用于将临时调度信息发送 给 UE。 其中， 处理单元 420按照临时调度信息调度 UE的时间与 UE接收来自第二系统的 数据的时间不重叠。 可选的， 第一系统为 LTE系统， 并为 UE提供服务的设备， 例如： LTE系统中正在为 UE提供服务的基站。 以第一系统为 LTE band 40， 第二系统为 ISM WLAN系统或 ISM BT系统为例， 处理 单元 420具体用于根据 UE的当前业务情况和 /或该基站的当前资源调度情况（例如对其控 制的其他 UE的资源调度情况） 生成临时调度信息。 或者， 接收单元 410还用于接收 UE 发送的建议调度信息，处理单元 420具体用于根据 UE的当前业务情况和 /或该基站的当前 资源调度情况 （例如对其控制的其他 UE的资源调度情况） 修改所述建议调度信息， 修 改后的调度信息为临时调度信息， 其中， 建议调度信息指示 UE建议基站如何调度 UE。 可选的， 处理单元还用于在 UE切换至目标基站之前， 将所述第一指示发送给所述目标 基站； 其中， 所述目标基站处于所述第一系统。 以第一系统为 LTE band 13或 LTE band 14， 第二系统为 GPS系统为例， 接收单元 410 还用于接收 UE发送的第二系统的调度信息， 第二系统的调度信息用于第二系统对 UE进 行调度。 处理单元 420具体用于根据所述第二系统的调度信息生成临时调度信息。 需要 说明的是，处理单元 420按照临时调度信息调度 UE的时间与 UE接收来自第二系统的数据 的时间不重叠， 也可理解为， 处理单元 420按照临时调度信息调度 UE的时间与第二系统 按照第二系统的调度信息调度 UE的时间不重叠。 可选的， 所述第二系统的调度信息与 所述第一指示携带在同一 RRC消息中； 或者， 所述接收单元 410还用于接收表示第二系 统的类型的第二指示， 所述第二系统的调度信息、 所述第一指示与第二指示携带在同一 个无线资源控制 RRC消息中。 相应的， 所述 UE在接收到接收单元 410发送的临时调度信 息后， 在基站未调度 UE的时段内接受第二系统按照第二系统的调度信息进行的调度， 例如接收接收第二系统的数据。 例如， 处理单元 430根据所述第二系统的调度信息生成 临时调度信息包括： 根据 UE的当前业务情况和 /或该基站的当前资源调度情况修改 UE发 送的调度信息， 并将修改后的调度信息作为临时调度信息。 可选的， 第二系统的调度信 息是经过 UE转换生成的以第一系统的时间为基准的调度信息， 其中， 所述转换包括将 调度信息由以第二系统的时间为基准转换为以第一系统的时间为基准。 可选的， 发送单 元 420还用于在 UE切换至目标基站之前， 将所述第一指示和所述第二系统的调度信息发 送给所述目标基站； 其中， 所述目标基站处于所述第一系统。 可选的， 接收单元 410还用于接收 UE发送的表示第一系统与第二系统间不存在干扰 的第一指示， 相应的， 处理单元 420还用于停止按照所述临时调度信息调度 UE。 进一步 的， 处理单元 420还用于通知 UE临时调度信息失效。 可选的， 本实施例中的临时调度信息包括： 调度周期、 一个调度周期内基站不调度 UE的起始时间和一个调度周期内基站不调度 UE的持续时间； 或者， 调度周期、 一个调 度周期内基站不调度 UE的起始时间和结束时间。 使用本实施例提供的装置可以避免 UE在两个频段邻近的系统中收发消息相互干 扰。 如图 5所示， 本发明的另一个实施例提供一种装置 50， 该装置 50可以用于实现本发 明其他实施例提供的调度方法中 UE完成的动作。 例如， 该装置 50包括收发单元 510和执 行单元 520。其中，收发单元 510用于向第一系统中的基站发送第一指示和建议调度信息， 所述第一指示表示第一系统与第二系统间存在干扰。 收发单元 510还用于接收基站发送 的确认消息。 执行单元 520用于按照所述建议调度信息接受基站的调度， 并在基站未调 度 UE的时段内接收第二系统的数据。 其中， 确认消息表示对第一指示和建议调度信息 的确认， 例如， 确认正确接收和 /或接受建议。 以第一系统为 LTE band40系统， 第二系统为 ISM WLAN系统或 ISM BT系统为例， 执行单元 520还用于， 在收发单元 510向第一系统中的基站发送第一指示之前， 判断所述 第一系统和第二系统间是否存在干扰； 如果所述第一系统和第二系统间存在干扰， 触发 收发单元 510发送所述第一指示给基站。 可选的， 收发单元 510还用于从基站获知所述临 时调度信息失效时， 并触发执行单元 520停止按照所述临时调度信息接受基站调度。 可 选的， 执行单元 520还用于判断出所述第一系统和第二系统间不存在干扰时， 触发收发 单元 510通知基站第一系统与第二系统不存在干扰。 可选的， 本实施例中的临时调度信息包括： 调度周期、 一个调度周期内基站不调度 UE的起始时间和一个调度周期内基站不调度 UE的持续时间； 或者， 调度周期、 一个调 度周期内基站不调度 UE的起始时间和结束时间。 本实施例提供的装置在两个频段邻近的系统中收发消息是不会相互干扰。 本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤是可以通 过程序来指令相关的硬件来完成， 所述的程序可以存储于一计算机可读取存储介质中， 所述的存储介质， 如： ROM/RAM、 磁碟、 光盘等。 例如， 程序可以按照如下步骤运行： 第一系统中的基站接收用户设备 UE发送的第 一指示， 所述第一指示表示第一系统与第二系统间存在干扰； 所述基站生成临时调度信 息， 并发送所述临时调度信息给 UE; 所述基站按照所述临时调度信息调度 UE， 基站按 照所述临时调度信息调度 UE的时间与 UE接收来自第二系统的数据的时间不重叠。 通过 该程序指令基站或其中的部分硬件来完成上述步骤， 可以避免 UE在两个频段邻近的系 统中收发消息相互干扰。 又如， 程序可以按照如下步骤运行： 向第一系统中的基站发送第一指示和建议调度 信息， 所述第一指示表示第一系统与第二系统间存在干扰； 所述 UE接收基站发送的确 认消息； 所述 UE按照所述建议调度信息接受基站的调度， 并在基站未调度 UE的时段内 接收第二系统的数据。 通过该程序指令 UE或其中的部分硬件来完成上述步骤， 可以避 免 UE在两个频段邻近的系统中收发消息相互干扰。 以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以作出若干改进和润饰， 这些改进和润饰也应视为 本发明的保护范围。
