- LTE Long Term Evolution
- LTE-A LTE-Advanced, LTE enhanced version
- 3G 3G module.
- Such a communication system module usually needs to cooperate with a base station to perform signal transmission and reception, thereby realizing functions such as making a call, sending and receiving a short message, a multimedia message, or surfing the Internet.
- the coexistence system module coexisting with this communication system module can be referred to as a WLAN module (usually used to connect to a network, can be wirelessly connected using a specified radio frequency band in a local area network environment), a Bluetooth module (usually used for Other mobile terminals perform short-distance data transmission) or GNSS modules (usually used for satellite positioning, data such as maps can be acquired from satellite navigation systems, and displayed).

- the specific sending action may be performed by the LTE module in the terminal device, which is equivalent to performing some internal devices in the terminal device.
- Information interaction For example, the ISM module can notify the LTE module of information related to its own working time, or can perform some statistics on the working status of the ISM module, and so on. For example, for the latter, the ISM module usually works when there is a service flow that needs to be transmitted, and does not work at other times. Therefore, it can be compared with the ISM by measuring the ISM module for a period of time.
- the working time related information of the module for example, the working time length of each work is counted, and these working time related parameters can be transmitted as auxiliary information to the base station of the mobile communication system.
- S102 The base station configures time division multiplexing configuration information according to the auxiliary information.

That is, as much as possible, ensure that each communication module does not send and receive signals at the same time to avoid mutual interference.
- the base station can then return the time division multiplexed configuration information to the terminal device.
- S103 Time division multiplexing is performed between each communication module according to time division multiplexing configuration information.
- the terminal device After receiving the time division multiplexing configuration information returned by the base station, the terminal device can perform time division multiplexing between the communication modules according to the configuration, thereby coordinating the work between the LTE module and the ISM module, so as to try to coordinate the work between the LTE module and the ISM module. Ensure that each communication module does not send and receive signals at the same time to avoid mutual interference.
- the working mode of the ISM module is divided into a power saving mode and a non-power saving mode, wherein the energy saving mode is generally divided into a periodic energy saving mode and a non-cyclic energy saving mode.
- the periodic energy-saving mode refers to the time when the ISM module wakes up periodically. The length of each wake-up can be fixed or changed. For example, for the WLAN module, defined in the IEEE802.il protocol.
- Periodic energy saving mode has general energy saving mode (Normol Power Saving) and Scheduled Automatic Power Save Delivery (S-APSD).
- the non-periodic power-saving mode means that the moment when the ISM module wakes up is non-periodic, and the length of time that each wake-up can be fixed or changed; for example, the same for the WLAN module, IEEE802.il protocol Unscheduled Automatic Power Save Delivery (U-APSD) is a non-periodic power saving mode.
- U-APSD Unscheduled Automatic Power Save Delivery
- the information related to the working time of the ISM module can refer to the working time length information of the ISM module.
- the ISM module usually works only when there is a traffic flow to be transmitted. Therefore, the working status of the ISM module can be counted for a period of time to obtain the work of the ISM module.
- Time length information The statistics of the working time length are equivalent to the working time characteristic information of the ISM module from the historical working record of the ISM module.
- the working time characteristic information has important reference value for the configuration of the time division multiplexing mode.
- the time length information of each work may include multiple types, for example, may include at least one of the following information: a minimum working time length required to ensure preset spectral efficiency, each work Average working time length, minimum working time per job, maximum working time per job, and so on.
- auxiliary information When the auxiliary information is transmitted to the base station to which the LTE module belongs, some or all of these parameters may be used as auxiliary information. If only some of the above parameters are sent to the base station, the base station can allocate the working time length of the ISM module according to the received parameters only when the time division multiplexing is performed; otherwise, if all the parameters are sent to the base station, the base station is the ISM module.
- assigning the working time length of time division multiplexing it can be comprehensively considered from multiple angles, so that the allocated time division multiplexing configuration information is more reasonable.
- the ISM module can be measured over a period of time to obtain the length of work for each job. Take the average of the working time length of each work, and get the average of the working time length of each work. Compare the working time length of each work, the smallest of which is the minimum working length of each work, and the largest is the maximum working time length of each work.
- the base station to which LTE belongs may allocate the working time length for the ISM module according to the above parameters. For example, if the average value of the working time length of each ISM module is sent to the base station as auxiliary information, the base station can make the working time length of the ISM module as close as possible to the parameter.
- the base station can make the working time length of the ISM module be as large as possible. Furthermore, if the maximum value of the working time length of each ISM module is sent to the base station as auxiliary information, the base station can make the working time length of the ISM module be as small as possible. Or, if the three parameters are sent to the base station as auxiliary information, the base station can make the working time length of the ISM module as close as possible to the average value, and is greater than the minimum value and smaller than the maximum value.
- This parameter refers to how long the ISM module needs to work for a minimum while ensuring that the ISM module achieves a certain spectral efficiency (usually the minimum required spectral efficiency).
- the working state of the ISM module can be measured for a period of time, the working time length of each working is obtained, and the rate obtained by the ISM module is measured for each working time length, and then can be combined.
- Other parameters in the system calculate the spectral efficiency of the ISM for each working time length. At the same time, for the ISM module, it usually has the minimum spectrum efficiency requirement. Therefore, it can be calculated that the minimum working time length is corresponding to the minimum spectrum efficiency requirement of the ISM module.
- the parameter of ensuring the minimum working time length required under the condition of preset spectral efficiency is provided as auxiliary information to the base station, and when the base station allocates working time to the ISM module, it can ensure that each ISM module is allocated as much as possible.
- the length of time for the second job is greater than this parameter.
- the ISM module is a WLAN module
- the WLAN module is assigned different working time lengths under the condition of ensuring the duty ratio of the working time length of the LTE module and the WLAN module.
- the throughput obtained is different.
- the duty ratio is 1:1, that is, the working time length of the LTE module and the WLAN module are the same in one cycle
- the rate obtained when the working time allocated to the WLAN module is 10 ms is smaller than
- the rate obtained when the working time allocated to the WLAN module is 20 ms.
- this is determined by a number of factors, such as the number of WLAN terminals in the WLAN network, the WLAN channel conditions, the error probability, and the like.
- the base station allocates the working time length to the WLAN module according to this, the factor can be considered, so that the spectrum efficiency of the WLAN module can be effectively improved.
- the base station can ensure the required duty ratio on the one hand.
- the final result is time division multiplexing between the various communication modules, that is, for an ISM module, it may only be in a preset time period. Work, other time periods have been assigned to other communication modules. Therefore, in this case, each ISM module can be allowed to use the power saving mode, so that the interference between the communication modules can be reduced, and the energy consumption can be reduced. Therefore, the technical solution provided by the embodiment of the present invention can be combined with the energy saving mode of the ISM module, which will be described in detail below.
- the energy saving mode can be divided into a periodic energy saving mode and a non-cyclic energy saving mode.
- the sleep time needs to be set in advance.
- the ISM module determines when to wake up according to the preset sleep time. That is, for the ISM module, if the periodic power saving mode can be supported, the sleep time information is preset.
- the ISM module in sleep mode the ISM module is divided into two states: sleep state and wake-up state. The ISM module can only work when it is awake, including data transmission and reception, etc. .
- the ISM module accesses the network, it is usually necessary to first obtain the AP's sleep time information through interaction with the AP (Access Point). Then the AP chooses to wake up when the ISM module wakes up. , send downstream data to it. Therefore, the ISM module needs to coordinate the sleep time with the AP. The AP interacts with the ISM module according to the coordinated sleep time information. Therefore, after the sleep time is coordinated, the ISM module can no longer wake up every time. Variety. Of course, if you need to change the sleep time information such as the time when the ISM wakes up, you need to re-coordinate with the AP and notify the AP of the modified sleep time information.
- the base station to which the LTE module belongs needs to allocate working time to the ISM module, that is, when it is scheduled to start working, how long each time.
- the sleep time information of the ISM module needs to be made.
- the auxiliary information is sent to the base station to which the LTE belongs. In this way, when the base station to which the LTE belongs allocates the working time of the time division multiplexing to the ISM module, the information can be used to determine when the ISM module starts working.
- the sleep time information of the ISM module actually belongs to a working time related information.
- the sleep time information of the ISM module can be sent as auxiliary information to the base station to which the LTE belongs.
- the sleep time information may include a wake-up time of the ISM module and a wake-up period.
- the base station to which the LTE module belongs can be made aware of when the ISM module wakes up and how long it will wake up after each wake up.
- the starting time of the working time of the ISM module may be set as the wake-up time of the ISM module, or earlier than the wake-up time of the ISM module. , and set the working time of each working of the ISM module to not exceed the duration of the ISM module wake up state.
- the ISM since the ISM always wakes up periodically, it is up to the terminal device to decide which wake-up time of the ISM module is sent as auxiliary information to the base station to which the LTE module belongs. For example, it may be the next wake-up time of the ISM module from the current time, or a wake-up time after several energy-saving cycles, and so on.
- the AP sends a beacon to the WLAN module when the WLAN module wakes up. (beacon) frame, through which the terminal device is notified that downlink data needs to be sent to it.
- beacon For example, if the received beacon frame includes a Traffic Indication Map (TIM) sent to the terminal, it indicates that the AP has downlink unicast data of the terminal device; if the received beacon frame is included and sent to The delivery traffic indication message (DTIM) of the terminal device indicates that the AP has downlink broadcast/multicast data of the terminal device.
- TIM Traffic Indication Map
- DTIM delivery traffic indication message
- the purpose of the WLAN module waking up is to receive the beacon frame sent by the AP. Therefore, the waking time of the ISM module can be determined by the time at which the terminal device receives the next beacon frame.
- the wake-up period of the WLAN module it can be determined according to the already configured system parameters.
- the IEEE 802.il protocol uses the Listenlnterval and DTIM period parameters respectively to indicate the period in which a WLAN module needs to receive a beacon frame containing TIM and DTIM. These two parameters are the beacon frame transmission period. An integer multiple of (usually 102.4ms). Therefore, according to the type of the beacon frame that the terminal needs to receive (the beacon frame including the TIM and/or the DTIM), the Listenlnterval and/or the DTIM period can be sent as the auxiliary information for the WLAN module to the base station to which the LTE module belongs.
- the terminal device can determine the WLAN module wake-up period according to the two parameters, and send the auxiliary information for the WLAN module to the base station to which the LTE module belongs.
- the sleep time information is used as the auxiliary information.
- the working time length information of the ISM module can be sent to the base station to which the LTE module belongs as auxiliary information. In this way, the base station to which the LTE module belongs can configure a more suitable working time length for the ISM module in time division multiplexing according to the working time length information of the ISM module.
- the length of the working time of the ISM module described herein is the same as that described above, and may also include the minimum working time required under the condition of ensuring the preset spectral efficiency, and the average work per work. The length of time, the minimum working time per job, and the maximum working time of each job. Similarly, the more auxiliary information is sent to the base station, the more comprehensive the base station can coordinate between the various communication modules.
- the terminal device can control the sleep time of the ISM module, that is, when there is a service that needs to be transmitted, it can wake up automatically, and after the service ends, it can automatically enter the sleep state. . Therefore, when the terminal device operates in the power-saving mode, the base station may not have to consider when the ISM module wakes up and wakes up for a long time, so when the auxiliary information is sent to the base station, only the ISM module can work only once. The time length information is sent to the base station as auxiliary information, and the base station can allocate the appropriate working time length for performing time division multiplexing for the ISM module.
- the ISM module works in the energy-saving mode, it can only enter the working state when waking up. Therefore, in the energy-saving mode, the working time length information of the ISM module can be more accurately called The length of work time of the ISM module after each wake up.
- the specific meanings of the parameters included in the working time length information of each working of the ISM module are the same as those described above, and are not described here.
- the terminal device will select according to the working mode of its own ISM module.
- the work time related information is sent as auxiliary information.
- the types of parameters sent and their specific meanings may be different.
- the number of terminal devices may be many, and the working mode of the ISM module in each terminal device may also be different. Therefore, in order to better distinguish the specific meaning of each parameter, when the auxiliary information is sent, in addition to the information about the working time length of the ISM module, the working mode of the ISM module can be sent as auxiliary information.
- Base station That is, the base station is made aware of whether the ISM is operating in the energy-saving mode or the non-energy-saving mode, and if it is the energy-saving mode, which is the energy-saving mode, in order to further clarify the meaning of the received parameters.
- the base station to which the LTE module belongs does not need to separately distinguish the working modes of the respective ISM modules for different terminal devices. Therefore, the base station to which the LTE module belongs can be notified in advance by other means, and the working mode of the ISM module in each terminal device, so that the base station can know the meaning of each parameter when receiving the auxiliary information.
- the working time related information of the ISM module can be sent to the base station to which the LTE module belongs as the auxiliary information, and then the base station to which the LTE module belongs can be the terminal according to the auxiliary information.
- Each communication module in the device configures time division multiplexing configuration information and returns it to the terminal device, so that the terminal device can utilize time division multiplexing configuration information to implement time division multiplexing between the communication modules. In this way, interference between the various modules in the terminal device can be effectively reduced.
- the specific working time-related information may be the working time length information of the ISM module. If the ISM module works in the periodic energy-saving mode, the specific working time-related information may be the sleep time information of the ISM module, including the waking time of the ISM module and the wake-up period; or, in addition to the sleep time information, may also include Information about the working time of the ISM module for each job.

[20] 图 2是示出作为本发明实施例提供的装置的示意图;
[21] 图 3是示出作为本发明实施例提供的另一装置的示意图; 以及
[22] 图 4是示出作为本发明的实施例中所采用的信息处理设备的个人计 算机的示例性结构的框图。
具体实施方式
[23] 下面参照附图来说明本发明实施例。
[24] 首先需要说明的是, 在本发明实施例中, 终端设备中的通信模块可 以包括通信系统模块, 以及与通信系统模块共存的共存系统模块。 其中, 通信系统模块通常是指 LTE ( Long Term Evolution, 长期演进方案)模 块,或者 LTE-A ( LTE- Advanced, LTE的增强版), 或者 3G模块等等。 这种通信系统模块通常需要与所属的基站相互配合, 进行信号的收发, 从而实现接打电话、 收发短信、 彩信或者上网等功能。
[25] 而与这种通信系统模块共存的共存系统模块就可以是指 WLAN模 块(通常用于连接网络, 可以在局域网络环境中使用指定射频波段进行 无线连接)、 蓝牙模块(通常用于与其他的移动终端进行短距离的数据传 输)或者 GNSS模块(通常用于卫星定位, 可以从卫星导航系统获取地 图等数据, 并进行显示)等等。 在本发明实施例中, 共存系统模块可以 是一个或多个上述通信模块。
[26] 在实际应用中, 上述共存系统模块常被称为使用工业, 科学和医学 ( ISM, Industrial, Scientific and Medical )频段的模块, 因此, 在本发 明实施例中, 为了方便描述, 也将这些共存系统模块简称为 ISM模块。 并假设终端设备中的通信系统模块为 LTE模块。 当然, 本领域技术人员 可以理解, 除了 LTE系统, 对于其他通信系统本发明实施例同样适用。
[27] 参见图 1, 本发明实施例提供的降低终端设备中通信模块间干扰的 方法包括以下步骤:
[28] S101:将与所述共存系统模块的工作时间相关的信息作为辅助信息, 发送给通信系统模块所属的基站;
[29] 需要说明的是,由于是将辅助信息发送到通信系统模块所属的基站, 因此, 具体的发送动作可以由终端设备中的 LTE模块来完成, 这样, 相 当于在终端设备内部需要进行一些信息的交互。 例如, ISM模块可以将 与自己的工作时间相关的信息通知 LTE模块, 或者, 还可以对 ISM模 块的工作状况进行一些统计, 等等。 例如, 对于后者, 由于 ISM模块通 常都是在有业务流需要传输时才会工作, 其他时间是不工作的, 因此, 就可以在一段时间内, 通过对 ISM模块的测量, 统计出与 ISM模块的 工作时间相关的信息, 例如, 统计出每次工作的工作时间长度等, 可以 将这些工作时间相关参数, 作为辅助信息发送给移动通信系统的基站。
[30] S102: 基站根据辅助信息配置时分复用配置信息;
[31] 基站在接收到辅助信息之后, 就可以为该终端设备分配时分复用配 置信息。 其中, 时分复用配置信息中可以包括各个通信模块(包括 LTE 模块以及 ISM模块)的工作时间起始点、 工作时间长度等等。 也即, 尽 量保证各个通信模块不要同时收发信号, 以避免相互干扰。 然后基站可 以将时分复用配置信息返回给终端设备。
[32] S103: 根据时分复用配置信息,在各个通信模块之间进行时分复用。
[33] 终端设备在接收到基站返回的时分复用配置信息之后, 就可以按照 该配置,在各个通信模块之间进行时分复用,以此来协调 LTE模块与 ISM 模块间的工作, 使得尽量保证各个通信模块不要同时收发信号, 以避免 相互干扰。
[34] 实际应用中, 如果 ISM模块的工作模式不同, 则具体的工作时间相 关信息也可能会有所不同。 其中, ISM模块的工作模式分为节能模式和 非节能模式, 其中, 节能模式通常又可以分为周期性节能模式和非周期 性节能模式。 周期性节能模式指的是 ISM模块醒来的时刻是周期性出现 的, 每次醒来的时间长度可以是固定的, 也可以是变化的, 例如, 对于 WLAN模块, IEEE802.il协议中定义的周期性节能模式有一般节能模式
( Normol Power Saving )和调度自动节能模式(Scheduled Automatic Power Save Delivery, S-APSD )两种。 非周期性节能模式指的是 ISM模 块醒来的时刻是非周期性出现的, 并且每次醒来的时间长度可以是固定 的, 也可以是变化的; 例如, 同样对于 WLAN模块, IEEE802.il协议 中定义的非调度自动节能模式 (Unscheduled Automatic Power Save Delivery, U-APSD )就是一种非周期性节能模式。 下面进行详细地介绍。 需要注意, 在以下的实施例的描述中, 对于终端设备中可包括的 ISM模 块的数量没有限定, 即, 终端设备中可包括一个或者多个 ISM模块。
[35] 首先, 如果 ISM模块处于非节能模式, 也即 ISM模块随时可以收 发信号, 则与 ISM模块的工作时间相关的信息可以是指 ISM模块每次 工作的工作时间长度信息。
[36] 如前文所述, ISM模块通常只在有业务流需要传输时才会工作, 因 此,就可以在一段时间内,对 ISM模块的工作状况进行统计,以得到 ISM 模块每次工作的工作时间长度信息。这些统计出来的工作时间长度信息, 相当于是从 ISM模块的历史工作记录中, 统计出 ISM模块的工作时间 特征信息, 该工作时间特征信息对于进行时分复用模式的配置具有重要 的参考价值。
[37] 其中, 每次工作的时间长度信息可以包括多种, 例如, 可以包括以 下信息中的至少一种: 在保证预置频谱效率的条件下所需的最小工作时 间长度, 每次工作的平均工作时间长度, 每次工作的最小工作时间长度, 每次工作的最大工作时间长度, 等等。 在向 LTE模块所属的基站发送辅 助信息时, 可以将这些参数中的部分或全部作为辅助信息。 如果只向基 站发送部分上述参数, 则基站就可以仅依据收到的参数, 为 ISM模块分 配时分复用时的工作时间长度; 否则, 如果将全部参数都发送给基站, 则基站在为 ISM模块分配时分复用时的工作时间长度时, 可以从多个角 度进行全面考虑, 使得分配的时分复用配置信息更加合理。
[38] 关于每次工作的工作时间长度的平均值、 最小值或最大值, 可以在 一段时间内, 对 ISM模块进行测量, 获取其每次工作的工作时间长度。 取各次工作的工作时间长度的平均值, 即可得到每次工作的工作时间长 度的平均值。 比较各次工作的工作时间长度, 其中最小者为每次工作的 工作时间长度的最小值, 最大者为每次工作的工作时间长度的最大值。
[39] LTE所属的基站可以依据上述参数,为 ISM模块分配每次的工作时 间长度。 例如, 如果将某 ISM模块每次工作的工作时间长度的平均值作 为辅助信息发送给了基站, 则基站就可以使该 ISM模块的工作时间长度 尽量接近该参数。 或者, 如果将某 ISM模块每次工作的工作时间长度的 最小值作为辅助信息发送给了基站, 则基站就可以使该 ISM模块的工作 时间长度尽量大于该参数。 再者, 如果将某 ISM模块每次工作的工作时 间长度的最大值作为辅助信息发送给了基站, 则基站就可以使该 ISM模 块的工作时间长度尽量小于参数。 又或者, 将这三个参数均作为辅助信 息发送给了基站, 则基站就可以使该 ISM模块的工作时间长度尽量接近 上述平均值, 并且大于上述最小值, 小于上述最大值。
[40] 关于保证预置频谱效率的条件下所需的最小工作时间长度, 下面进 行一些解释。 该参数是指, 在保证 ISM模块获得一定的频谱效率(通常 可以设为所需频谱效率的最小值) 的情况下, ISM模块最少需要工作多 长时间。 具体在获取该参数时, 可以在一段时间内对 ISM模块的工作状 况进行测量, 获知每次工作的工作时间长度, 并测量在每种工作时间长 度下, ISM模块所获得的速率, 进而可以结合系统中的其他参数计算出 ISM在每种工作时间长度下的频谱效率。 同时, 对于 ISM模块而言, 通 常具有最小频谱效率要求, 因此, 就可以统计出, 在保证 ISM模块最小 频谱效率要求的情况下, 对应的最小工作时间长度。
[41] 将该保证预置频谱效率的条件下所需的最小工作时间长度这一参数 作为辅助信息提供给基站, 基站在为 ISM模块分配工作时间时, 就可以 尽量保证分配给 ISM模块的每次工作的时间长度要大于该参数。 下面简 单介绍, 之所以要这样分配的原因。
[42] 假设 ISM模块为 WLAN模块, 则根据实验及仿真结果可以得知, 在保证 LTE模块与 WLAN模块工作时间长度的占空比的情况下, 为 WLAN模块分配不同的工作时间长度, 其所获得的吞吐量是不同的。 例 如, 在占空比为 1:1的情况下, 也即在一个周期内, LTE模块与 WLAN 模块的工作时间长度相同,则分配给 WLAN模块的工作时间长度为 10ms 时所获得的速率, 小于分配给 WLAN模块的工作时间长度为 20ms时所 获得的速率。 当然, 这个 由多个因素决定, 例如, WLAN网络中的 WLAN终端数目、 WLAN信道状况、错误概率等等。 将该参数提供给基
站, 基站据此给 WLAN模块分配工作时间长度时, 可以考虑该因素, 从 而可以有效地提高 WLAN模块的频谱效率。 例如, 为了提高 WLAN模 块的频谱效率,基站在为 WLAN模块分配工作时间时, 就可以一方面保 证所需的占空比, 另一方面, 需要保证分配给 WLAN模块的每次工作时 间长度要大于该参数。
[43] 当然, 由于在本发明实施例中, 最终的结果是在各个通信模块之间 进行时分复用, 也即, 对于一个 ISM模块而言, 仅在预先设置好的时间 段内才可能会工作, 其他的时间段已经分配给了其他通信模块。 因此, 在这种情况下, 可以允许各个 ISM模块使用节能模式, 这样, 在降低通 信模块之间的干扰的同时, 还可以达到降低能量消耗的目的。 因此, 可 以将本发明实施例提供的技术方案与 ISM模块的节能模式相结合, 下面 对此进行详细地介绍。
[44] 需要说明的是, 如前文所述, 对于一个 ISM模块而言, 节能模式可 以分为周期性节能模式和非周期性节能模式。 其中, 对于周期性节能模 式而言, 需要预先设置休眠时间, ISM模块是按照预先设置好的休眠时 间, 来决定何时醒来。 也即, 对于 ISM模块而言, 如果能够支持周期性 节能模式, 则其休眠时间信息是预先设置好的。 另一方面, 对于休眠模 式的 ISM模块而言, ISM模块分为两种状态:休眠状态及醒来状态, ISM 模块只有在处于醒来状态时, 才能够进行工作, 包括进行数据的收发等 等。 也正是因为如此, 在 ISM模块接入网络之后, 通常还需要首先通过 与 AP ( Access Point, 接入点) 的交互使 AP获得自己的休眠时间信息, 然后 AP会选择在 ISM模块醒来时, 向其发送下行数据。 因此, 相当于 需要 ISM模块与 AP协调好休眠时间, AP会按照协调好的休眠时间信 息与 ISM模块之间进行交互, 因此, 协调好休眠时间之后, ISM模块每 次醒来的时刻就不能再变化。 当然, 如果需要改变 ISM醒来的时刻等休 眠时间信息, 则需要重新与 AP进行协调, 将修改后的休眠时间信息, 重新通知给 AP。
[45] 而对于本发明实施例而言, LTE模块所属的基站需要为 ISM模块分 配工作时间, 也即分配其何时开始工作, 每次工作多长时间。 而在周期 性节能模式下, 由于与 AP协调好休眠时间信息之后, ISM模块每次醒 来的时刻不能再发生变化, 因此, 就需要将 ISM模块的休眠时间信息作
为辅助信息发送给 LTE所属的基站。 这样, 在 LTE所属的基站为 ISM 模块分配时分复用的工作时间时, 可以依据该信息, 来确定 ISM模块何 时开始工作。
[46] 需要说明的是, 由于 ISM模块只有在醒来时才能够工作, 因此 ISM 模块的休眠时间信息实际上也属于一种工作时间相关信息。
[47] 可见, 如果 ISM模块工作于周期性节能模式, 则可以将 ISM模块 的休眠时间信息作为辅助信息发送给 LTE所属的基站。 具体的, 休眠时 间信息可以包括 ISM模块的醒来时刻以及醒来周期。 也就是说, 可以让 LTE模块所属的基站知悉 ISM模块何时醒来,每次醒来之后醒来状态会 持续多长时间。 LTE模块所属的基站在根据这些信息来确定在通信模块 之间进行时分复用时,可以将 ISM模块的工作时间起始点设为该 ISM模 块的醒来时刻, 或者早于 ISM模块的醒来时刻, 并将 ISM模块每次工 作的工作时间长度设置为不超过 ISM模块醒来状态的持续时间。
[48] 其中, 由于 ISM总是周期性地醒来, 因此, 将 ISM模块的哪个醒 来时刻作为辅助信息发送给 LTE模块所属的基站, 终端设备是可以自己 决定的。 例如, 可以是从当前时刻起, ISM模块的下一个醒来时刻, 或 者也可以隔几个节能周期之后的一个醒来时刻, 等等。
[49] 需要说明的是, 如果 ISM模块是 WLAN模块, 则对于一般节能模 式而言,如果 AP上产生了关于 ISM模块的下行数据,则 AP会在 WLAN 模块醒来时刻向 WLAN模块发送信标( beacon )帧, 通过该信标帧来通 知终端设备有下行数据需要向其发送。 例如, 如果接收到的信标帧包含 发送给该终端的流指示映射 ( Traffic Indication Map,TIM ), 则表明 AP 上有该终端设备的下行单播数据; 如果接收到的信标帧包含发送给该终 端设备的传输流指示消息( Delivery Traffic Indication Message, DTIM ), 则表明 AP上有该终端设备的下行广播 /组播数据。 换言之, WLAN模块 醒来的目的就是为了接收 AP发送的信标帧。 因此, 关于 ISM模块的醒 来时刻, 可以由终端设备接收到下一个信标(beacon )帧的时刻来确定。
[50] 而关于 WLAN模块的醒来周期,可以根据已经配置好的系统参数来 确定。 例如, 对于一般节能模式而言, IEEE802.il 协议中分别用 Listenlnterval和 DTIM period两个参数表明一个 WLAN模块需要接收 包含 TIM和 DTIM的 beacon帧的周期。 这两个参数是信标帧发送周期
(通常为 102.4ms )的整数倍。因此根据终端需要接收的信标帧的类型(包 含 TIM和 /或 DTIM的信标帧),可以将 Listenlnterval和 /或 DTIM period 作为针对 WLAN模块的辅助信息发送给 LTE模块所属的基站。 对于调 度自动节能模式, WLAN模块醒来的时间是由服务开始时间( the service start time )和最小月良务间隔 ( minimum service interval )来决定的。 因 此终端设备可以根据这两个参数确定 WLAN模块醒来周期,并作为针对 WLAN模块的辅助信息发送给 LTE模块所属的基站。
[51] 当然, 在实际应用中, 为了使得基站在分配时分复用配置信息时更 加合理, 对于前述 ISM模块工作于周期性节能模式的情况下, 在将休眠 时间信息作为辅助信息的同时, 还可以将 ISM模块每次工作的工作时间 长度信息,一并作为辅助信息,发送给 LTE模块所属的基站。这样, LTE 模块所属的基站就可以根据 ISM模块每次工作的工作时间长度信息, 为 ISM模块在时分复用时配置更加合适的工作时间长度。
[52] 其中,这里所述的 ISM模块每次的工作时间长度,与前文所述相同, 也可以包括在保证预置频谱效率的条件下所需的最小工作时间长度, 每 次工作的平均工作时间长度, 每次工作的最小工作时间长度, 每次工作 的最大工作时间长度中的任意一种或多种。 同样, 如果发送给基站的辅 助信息越多, 基站就可以越全面地在各个通信模块之间进行协调。
[53] 此外, 在非周期性节能模式下, 终端设备可以对 ISM模块的休眠时 间进行控制, 也即, 当有业务需要传输时, 可以自动醒来, 业务结束之 后, 就可以自动进入休眠状态。 因此, 当终端设备工作于这种节能模式 下时, 基站可以不必考虑 ISM模块何时醒来以及醒来多长时间, 因此在 向基站发送辅助信息时, 可以仅将 ISM模块每次工作的工作时间长度信 息作为辅助信息发送给基站即可, 基站可以据此为 ISM模块分配在进行 时分复用时合适的工作时间长度。
[54] 需要说明的是, 由于 ISM模块是工作于节能模式, 只有醒来时才能 进入工作状态, 因此, 在节能模式下, ISM模块每次工作的工作时间长 度信息, 可以更加准确地称为 ISM模块每次醒来后工作的工作时间长度 信息。 关于 ISM模块每次工作的工作时间长度信息包含的各个参数的具 体含义, 与前文所述相同, 这里不再赘述。
[55] 需要说明的是, 终端设备会根据自己的 ISM模块的工作模式, 选择
工作时间相关信息作为辅助信息进行发送。 但是在 ISM模块处于不同的 工作模式下, 发送的参数种类及其具体含义可能会有所不同。 而在实际 应用中, 终端设备的数量可能有很多, 各个终端设备中的 ISM模块的工 作方式也可能会不同。 因此, 为了^ ^站能够更好地区分出各个参数的 具体含义, 在发送辅助信息时, 除了 ISM模块的工作时间长度相关信息 之外,还可以将 ISM模块的工作模式作为辅助信息,发送给基站。也即, 使得基站知晓 ISM是工作于节能模式还是非节能模式,如果是节能模式, 具体又是哪种节能模式, 以便进一步明确接收到的各个参数的含义。
[56] 当然, 在实际应用中, 也不排除各个终端设备中的 ISM模块都工作 于相同的工作模式的情况。 在这种情况下, LTE模块所属的基站就不需 要分别针对不同的终端设备, 区分各自 ISM模块的工作模式。 因此, 可 以预先通过其他方式通知 LTE模块所属的基站,各个终端设备中的 ISM 模块是哪种工作模式, 这样, 基站在接收到辅助信息时, 同样能够知晓 各个参数的含义。
[57] 由以上所述可以看出, 本发明实施例可以将 ISM模块的工作时间相 关信息作为辅助信息, 发送给 LTE模块所属的基站, 然后 LTE模块所 属的基站就可以根据这些辅助信息为终端设备中的各个通信模块配置时 分复用配置信息, 再将其返回给终端设备, 这样, 终端设备就可以利用 时分复用配置信息, 在各个通信模块之间实现时分复用。 这样, 可以有 效地降低终端设备中各个模块之间的干扰。
[58] 其中, 如果 ISM模块工作于非节能模式或非周期性节能模式, 则具 体的工作时间相关信息,可以是 ISM模块每次工作的工作时间长度信息。 如果 ISM模块工作于周期性节能模式, 则具体的工作时间相关信息, 可 以是 ISM模块的休眠时间信息, 包括 ISM模块醒来时刻以及醒来的周 期; 或者, 除了休眠时间信息以外, 还可以包括 ISM模块每次工作的工 作时间长度信息。
[59] 与本发明实施例提供的降低终端设备中通信模块间干扰的方法 相对应, 本发明实施例还提供了一种降低终端设备中通信模块间 干扰的装置, 同样, 终端设备中的通信模块可以包括终端设备中的 通信系统模块, 以及与通信系统模块共存的共存系统模块, 参见图 2, 该 装置可以包括:
[60] 发送单元 201, 配置为将与共存系统模块的工作时间相关的信息作 为辅助信息发送给所述通信系统模块所属的基站;

[65] 其中, 共存系统模块的休眠时间信息可以包括共存系统模块醒来时 刻以及醒来的周期。
[66] 当然, 为了基站能够更加全面地了解 ISM模块的工作时间相关信 息, 在上述共存模块工作于周期性自动节能模式时, 发送单元 201发送 的所述共存系统模块的工作时间相关信息除了休眠时间信息以外, 还可 以包括共存系统模块每次工作的工作时间长度信息。
[67] 其中, 工作时间长度信息可以包括以下中的任意一种或者任意多种 的组合: 在保证预置频谱效率的条件下所需的最小工作时间长度, 各次 工作的平均工作时间长度, 每次工作的最小工作时间长度, 每次工作的 最大工作时间长度。
[68] 为了便于基站明确各个参数的具体含义, 参见图 3, 该装置还可以 包括:
[69] 工作模式发送单元 204, 配置为将共存系统模块的工作模式信息作 为辅助信息发送给基站。
[70] 图 2 - 3 中示出的根据本发明实施例的上述装置及其各个组成部件 例如可以被配置成按照上述参见图 1 中所示实施例的方法的相应流程进 行操作, 具体细节可参见上述描述, 在此不再赘述。
[71] 根据本发明实施例的上述装置, 能够将与共存系统模块的工作时间 相关的信息作为辅助信息发送给通信系统所属的基站, 这样基站就可以 为该移动终端的各通信模块配置时分复用配置信息,并返回给终端设备, 终端设备可以依据基站返回的时分复用配置信息, 在各个通信模块之间 进行时分复用, 这样, 可以降低各通信模块之间的干扰。
