- Step 230 Set, by using an arbitration controller, a flag of a radio access mode to which an antenna resource is allocated, to indicate that the antenna resource is allocated to a radio access mode in which the flag bit is set.
- the flag bit can be one or more. For example, when the flag bit is one, different wireless values can be used to identify which wireless access mode the antenna resource is currently assigned to. When there are multiple flag bits, each radio access mode may be assigned a flag bit, and the "1, 0" flag is assigned to the radio access mode.

- FIG. 3 is a flowchart of a method for transmitting and receiving a wireless signal according to Embodiment 3 of the present invention.
- a method for sharing a plurality of wireless access modes is still applicable, and the coexistence of WIFI and BT is taken as an example.
- the arbitration controller can be placed in the WIFI driver or in the BT driver.
- WIFI is used as an example (BT has the same process).
- the embodiment is based on the foregoing first embodiment, and the operation for obtaining a wireless signal receiving and receiving request of the wireless access mode includes the following steps:

- the kernel thread of the arbitration controller is configured in a wireless access mode driver, for example, configured.
- the kernel thread of the arbitration controller queries the CPU whether the event notification is available, and if so, is sent by the CPU to the Kernel thread of the arbitration controller;
- Step 320 When an event notification is received by the kernel thread of the arbitration controller, read whether there is a wireless signal transceiving request from the driving of the other wireless access mode; for example, reading whether the BT wireless signal is transmitted or received from the BT driver request.

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 术人员在没有作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。
实施例一
图 1为本发明实施例一提供的无线信号收发方法流程图, 该方法应用于多种无线接 入方式共存进行无线信号收发的场景, 特别是多种无线接入方式共用天线的情况。 该方 法可以由无线信号收发装置来执行, 该装置可以通过硬件和 /或软件的方式实现, 集成 于存在多种无线接入方式共存的网元设备中。例如同时具有两种无线接入方式的终端设 备中。 本实施例的方法可以包括:
步骤 110、 获取到一种无线接入方式的无线信号收发请求;
上述的一种无线接入方式可以是至少两种无线接入方式中的任意一种, 即任意一种 无线接入方式产生了信号收发需求。
步骤 120、 根据所述无线信号收发请求, 基于时分复用方式为至少两种无线接入方 式中的一种无线接入方式分配天线资源;
其中, 至少两种无线接入方式可以为 WIFI或 BT方式。 分配天线资源是指将天线分 配给 WIFI使用, 这时 BT就不能使用天线收发数据; 或分配给 BT使用, 这时 WIFI不能 使用天线收发数据。 时分复用方式即将天线分时地分配给不同的无线接入方式来使用, 例如 WIFI 和 BT轮流使用天线资源, 或在单位时间内 WIFI 和 BT其中一种使用天线资 源次数可以较多。
本实施例,通过基于时分复用方式为多种无线接入方式的一种无线接入方式分配天 线资源, 且用户察觉不到天线资源的切换, 实现多种无线接入方式的近距离共存, 不会 出现干扰现象, 解决了现有技术方案的不足, 提高了网络性能。
在上述技术方案中, 根据所述无线信号收发请求, 基于时分复用方式为至少两种无 线接入方式中的一种无线接入方式分配天线资源的操作可优选根据所述无线信号收发 请求, 基于至少两种无线接入方式的优先级, 将当前天线资源分配给优先级高的所关联 的无线接入方式, 还可以优选包括如下步骤:
步骤 121、 根据所述无线信号收发请求, 识别当前天线资源的使用状况; 步骤 122、 若当前天线资源的使用状况是空闲, 则将当前天线资源分配给发起所述 无线信号收发请求的无线接入方式;
步骤 123、 若当前天线资源的使用状况是正在使用, 则判断正在使用天线资源的当 前无线接入方式与发起所述无线信号收发请求的无线接入方式的优先级,将当前天线资 源分配给优先级高的无线接入方式。
上述方案中, 一方面基于按需分配原则, 另一方面在同时产生天线使用需求时, 可 根据优先级分配天线资源, 优先级可以根据不同场景预先设置, 例如一般场景时当同时 存在 wifi和 BT, 默认 BT优先级低于 wifi, 若是 BT语音数据, 则优先级高于 wifi ; 优 先级还可以按其他方式设置, 此处不再举例。
本实施例的技术方案, 除了按照无线接入方式的信号收发请求分配资源外, 还可以 按照各无线接入方式各自设定的轮询周期,将天线资源分别分配给各无线接入方式以收 发无线信号, 保持与无线网络的连接。
在按照各无线接入方式各自设定的轮询周期,将天线资源分别分配给各无线接入方 式以收发无线信号之前,还可以分别识别各无线接入方式是否在设定时间内没有使用天 线资源, 若是, 则触发按照轮询周期收发无线信号的机制。
上述技术方案是为了保持各种无线接入方式需要保持与网络的持续连接, 因而每隔 设定的时间就需要利用天线进行信号收发, 与网络联系。 各种无线接入方式的轮询周期 可以不同, 以减少发生资源争抢的现象。
实施例二
图 2a为本发明实施例二提供的无线信号收发方法的流程图, 图 2b为本发明实施例 二所适用的硬件结构示意图。 本实施例的技术方案可适用于共用天线的终端设备中。 该 终端设备包括射频天线模块 21、 WIFI模块 22、 BT模块 23和仲裁控制器 24。 其中, 所 述仲裁控制器 24可以为现场可编程门阵列 (FPGA) 或复杂可编程逻辑器件 (CPLD) , 能够接收 WIFI模块 22和 BT模块 23的传输请求, 即无线信号收发请求, 而后分配天线 资源, 进而接收数据传输, 提供给射频天线模块 21。
即, 上述实施例中, 根据所述无线信号收发请求, 基于时分复用方式为至少两种无 线接入方式中的一种无线接入方式分配天线资源的操作包括如下步骤:
步骤 210、 通过仲裁控制器监听第一外部硬件中断, 其中, 所述第一外部硬件中断 为一种无线接入方式的无线处理元件在产生信号收发请求时向所述仲裁控制器发送; 例如, WIFI模块和 BT模块的无线处理元件均可能产生信号收发请求, 此时即向仲 裁控制器发送一个外部硬件中断。
步骤 220、 通过仲裁控制器监听到所述第一外部硬件中断时, 调用相应的中断处理 函数, 基于时分复用方式为至少两种无线接入方式中的一种无线接入方式分配天线资
源;
步骤 230、 通过仲裁控制器将分配有天线资源的无线接入方式的标志位进行置位, 以指示将天线资源分配给标志位被置位的无线接入方式;
标志位可以为一个或多个, 例如, 标志位为一个时, 可以通过不同的数值标识天线 资源当前分配给哪个无线接入方式。 标志位为多个时, 可以为每个无线接入方式分配一 个标志位, 以 " 1、 0"标识是否分配给该无线接入方式。 优选可以设定标志位为一个, 标识值为 "0、 1、 2、 3" , 其中 "0"表示 WIFI、 BT都不传输, " 1 "表示 WIFI传输, BT不传输, "2"表示 WIFI不传输, BT传输, "3"表示 WIFI、 BT都需要传输。 若出 现两种无线接入方式都传输的情况, 可以进一步进行天线资源的分配后再置位。
步骤 240、 通过仲裁控制器监听第二外部硬件中断, 其中, 所述第二外部硬件中断 为该无线接入方式的基带芯片完成信号收发时向所述仲裁控制器发送;
步骤 250、 通过仲裁控制器监听到所述第二外部硬件中断时, 仲裁控制器将分配给 该无线接入方式的标志位进行复位。
本实施例通过采用 FPGA或 CPLD实现仲裁控制器, 并基于时分复用方式为无线接入 方式分配天线资源, 实现 WIFI和 BT近距离共存, 解决现有技术方案的不足, 提高网络 性能, 由于 FPGA和 CPLD处理速度快, 因此本实施例可以满足对网络性能要求较为苛刻 的场景。
实施例三
图 3为本发明实施例三提供的无线信号收发方法的流程图,本实施例中仍可适用于 共用多种无线接入方式的终端设备中, 以 WIFI和 BT共存为例。仲裁控制器可置于 WIFI 的驱动内, 也可置于 BT驱动内, 为方便说明以 WIFI为例 (BT具有同样过程)。
本实施例以前述实施例一为基础, 且其中获取到一种无线接入方式的无线信号收发 请求的操作具体包括如下步骤:
步骤 310、 采用定时器周期性的产生事件通知, 并发送至仲裁控制器的内核线程; 其中, 所述仲裁控制器的内核线程配置在一种无线接入方式的驱动中, 例如配置在
WIFI的驱动中,为避免影响内核系统的整体效率,所述仲裁控制器的内核线程在取得 CPU 的控制权后, 会向 CPU查询是否有所述事件通知, 如果有则由 CPU发送至所述仲裁控制 器的内核线程;
步骤 320、 当通过仲裁控制器的内核线程监听到有事件通知时, 从其它无线接入方 式的驱动中读取是否存在无线信号收发请求; 例如从 BT驱动中读取是否存在 BT的无线 信号收发请求。 若是, 则执行步骤 330, 若否, 则内核线程释放仲裁控制器对 CPU的控
制权, 等待下一个事件通知。
步骤 330、 通过仲裁控制器读取存在的无线信号收发请求。
仲裁控制器在分配了天线资源后,可以切换各种无线接入方式与天线的连接关系而 切换对天线的使用。
本实施例通过仲裁控制器放置于无线收发方式的驱动内, 可以减少硬件成本。 同时 基于周期性的事件通知来触发仲裁控制器获得驱动的 CPU的控制权, 能够降低对 CPU的 占用率。
