技术领域technical field
本发明涉及通信技术领域，尤其涉及一种共享频谱方法和装置。The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for sharing a spectrum.
背景技术Background technique
在现代通信中，采用频谱管理有效地利用无线频谱进行，例如，将频谱分为授权频谱和非授权频谱，其中，授权频谱为授权给某个移动运营商或者某种移动技术（如通用移动通信系统(Universal Mobile Telecommunications System，简称UMTS)，或者，长期演进（Long Term Evolution，简称LTE））使用的频谱，非授权频谱为划分给非授权用户（如家庭用户）使用的频谱。In modern communications, spectrum management is used to effectively utilize the wireless spectrum, for example, the spectrum is divided into licensed spectrum and unlicensed spectrum, where licensed spectrum is licensed to a mobile operator or a mobile technology (such as universal mobile communication System (Universal Mobile Telecommunications System, UMTS for short), or Long Term Evolution (Long Term Evolution, LTE for short) uses the spectrum, and the unlicensed spectrum is the spectrum allocated for use by unlicensed users (such as home users).
在现有技术中，在无线保真（Wireless Fidelity，简称Wi-Fi）网络中，可以通过请求发送（Request-To-Send,简称RTS）帧和通过允许发送（Clear-To-Send，简称CTS）帧协调使用非授权频谱，该RTS帧或CTS帧包括持续时间值，其中，该持续时间值用于指示Wi-Fi站点使用该非授权频谱的时间，同时，当其他Wi-Fi站点收到该RTS帧或者CTS帧后，将不会在该预留时间内使用该非授权频谱。In the prior art, in a Wireless Fidelity (Wireless Fidelity, Wi-Fi for short) network, a request to send (Request-To-Send, RTS for short) frame and a Clear-To-Send (CTS for short) frame can be used. ) frame coordinated use of unlicensed spectrum, the RTS frame or CTS frame includes a duration value, where the duration value is used to indicate when the Wi-Fi station uses the unlicensed spectrum, and when other Wi-Fi stations receive After the RTS frame or the CTS frame, the unlicensed spectrum will not be used within the reserved time.
然而，移动运营商利用非授权频谱为用户提供通信服务时，通过类似于CTS帧的信道预留帧协调使用非授权频谱，在多个eNB同时发送信道预留帧时会导致碰撞，导致多个eNB同时在相同的频谱资源上进行数据调度和传输，从而造成基站之间的干扰，进而导致频谱利用率的下降。However, when mobile operators use unlicensed spectrum to provide communication services for users, they coordinate the use of unlicensed spectrum through channel reservation frames similar to CTS frames. The eNB performs data scheduling and transmission on the same spectrum resource at the same time, thereby causing interference between the base stations, which in turn leads to a decrease in spectrum utilization.

The embodiments of the present invention will be described in detail below.
图1为本发明共享频谱方法一个实施例的流程图。如图1所示，本实施例提供的共享频谱方法具体包括如下：FIG. 1 is a flow chart of an embodiment of a spectrum sharing method according to the present invention. As shown in FIG. 1 , the spectrum sharing method provided in this embodiment specifically includes the following:
步骤101、第二基站检测第一基站发送的第一频谱占用信息。Step 101: The second base station detects the first spectrum occupation information sent by the first base station.
在本实施例中，对于第二基站检测第一基站发送的第一频谱占用信息的适用场景至少包括以下两种：In this embodiment, applicable scenarios for the second base station to detect the first spectrum occupancy information sent by the first base station include at least the following two:
第一种适用场景，第二基站在第一频谱上发送信道预留帧之后，第二基站检测第一基站发送的第一频谱占用信息，其中，该信道预留帧用以指示为第二基站预留第一频谱。In the first applicable scenario, after the second base station sends a channel reservation frame on the first spectrum, the second base station detects the first spectrum occupancy information sent by the first base station, where the channel reservation frame is used to indicate that the second base station is the second base station. Reserve the first spectrum.
第二种适用场景，第二基站在第一频谱上发送信道预留帧之后，并在使用第一频谱的过程中，第二基站检测第一基站发送的第一频谱占用信息。In the second applicable scenario, after the second base station sends the channel reservation frame on the first frequency spectrum, and in the process of using the first frequency spectrum, the second base station detects the first frequency spectrum occupancy information sent by the first base station.
步骤102、第二基站没有接收到第一基站发送的第一频谱占用信息，或者，第二基站接收到第一基站发送的第一频谱占用信息，并确定第一基站发送的第一占用优先级小于第二基站的第二占用优先级时，第二基站通过第一频谱调度数据。Step 102: The second base station does not receive the first spectrum occupancy information sent by the first base station, or the second base station receives the first spectrum occupancy information sent by the first base station, and determines the first occupancy priority sent by the first base station When it is smaller than the second occupation priority of the second base station, the second base station schedules data through the first frequency spectrum.
在本实施例中，对应于上述的第一种适用场景，第二基站没有接收到第一基站发送的第一频谱占用信息，第二基站可以通过第一频谱调度数据。In this embodiment, corresponding to the above-mentioned first applicable scenario, the second base station does not receive the first spectrum occupation information sent by the first base station, and the second base station can schedule data through the first spectrum.
不论是上述的哪种适用场景，第二基站接收到第一基站发送的第一频谱占用信息，并确定第一基站发送的第一占用优先级小于第二基站的第二占用优先级时，第二基站可以通过第一频谱调度数据。No matter which of the above applicable scenarios, the second base station receives the first spectrum occupancy information sent by the first base station and determines that the first occupancy priority sent by the first base station is lower than the second occupancy priority of the second base station. The second base station may schedule data through the first frequency spectrum.
具体的，第二基站可以根据第一频谱占用信息，确定所述第一基站准备占用的第一预留频谱与第一频谱之间重叠；接着，第二基站将第一占用优先级与第二占用优先级进行比较，确定是否通过第一频谱调度数据。Specifically, the second base station may determine, according to the first spectrum occupancy information, the overlap between the first reserved spectrum that the first base station intends to occupy and the first spectrum; then, the second base station associates the first occupation priority with the second The occupancy priorities are compared to determine whether to schedule data through the first spectrum.
进一步的，第二基站将第一占用优先级与第二占用优先级进行比较，确定是否通过第一频谱调度数据，具体可以包括：Further, the second base station compares the first occupation priority with the second occupation priority, and determines whether to schedule data through the first spectrum, which may specifically include:
第二基站确定第二占用优先级是否大于或等于第一占用优先级，第一占用优先级为第一基站在第一预设范围内生成的数值，第二占用优先级为第二基站在第二预设范围内生成的数值，其中，第一占用优先级可以是第一基站在第一预设范围内随机生成的数值，或者，第一占用优先级可以是第一基站在第一预设范围内按照一定规则生成的数值，类似的，第二占用优先级可以是第二基站在第二预设范围内随机生成的数值，或者，第二占用优先级可以是第二基站在第二预设范围内按照一定规则生成的数值。若是，则确定通过第一频谱调度数据；或者，若否，则确定不通过第一频谱调度数据。需要说明的是，第一预设范围，和/或第二预设范围可以是第一基站与第二基站间预先约定的一个数值；或者，第一预设范围，和/或第二预设范围可以是基站之间预先约定的多个数值。进一步的，若第一预设范围包括多个数值，或者第二预设范围包括多个数值，则第一预设范围为根据第一基站将要调度数据的类型确定的，所述第二预设范围为根据第二基站将要调度数据的类型确定的。例如，高优先级数据（如语音数据）在（0,4）范围中生成随机数，低优先级数据（如上网业务数据）在（0,8）范围中生成随机数，也就是说，调度越高优先级数据的基站生成的随机数越小。The second base station determines whether the second occupation priority is greater than or equal to the first occupation priority, where the first occupation priority is a value generated by the first base station within the first preset range, and the second occupation priority is the second occupation priority in the first Two values generated within a preset range, where the first occupation priority may be a value randomly generated by the first base station within the first preset range, or the first occupation priority may be the first base station in the first preset A value generated according to certain rules within the range. Similarly, the second occupancy priority may be a value randomly generated by the second base station within the second preset range, or the second occupancy priority may be the second base station in the second preset range. Set a value within a range that is generated according to certain rules. If so, it is determined that the data is scheduled through the first spectrum; or, if not, it is determined that the data is not scheduled through the first spectrum. It should be noted that the first preset range and/or the second preset range may be a value pre-agreed between the first base station and the second base station; or, the first preset range and/or the second preset range The range may be a plurality of values pre-agreed between the base stations. Further, if the first preset range includes multiple values, or the second preset range includes multiple values, the first preset range is determined according to the type of data to be scheduled by the first base station, and the second preset range is determined according to the type of data to be scheduled by the first base station. The range is determined according to the type of data to be scheduled by the second base station. For example, high-priority data (such as voice data) generates random numbers in the (0,4) range, and low-priority data (such as Internet service data) generates random numbers in the (0,8) range, that is, scheduling The random number generated by the base station for higher priority data is smaller.
在本实施例中，通过第二基站检测第一基站发送的第一频谱占用信In this embodiment, the first spectrum occupancy information sent by the first base station is detected by the second base station.
息，接着，第二基站没有接收到第一基站发送的第一频谱占用信息，或者，第二基站接收到第一基站发送的第一频谱占用信息，并确定第一基站发送的第一占用优先级小于所述第二基站的第二占用优先级时，第二基站通过第一频谱调度数据。实现了不同基站在同一频谱上调度数据，从而降低了不同基站使用同一频谱的干扰，进而提高了频谱利用效率和系统吞吐量。Then, the second base station does not receive the first spectrum occupancy information sent by the first base station, or the second base station receives the first spectrum occupancy information sent by the first base station, and determines that the first occupancy information sent by the first base station has priority When the second occupancy priority is lower than the second occupation priority of the second base station, the second base station schedules data through the first spectrum. It realizes that different base stations schedule data on the same frequency spectrum, thereby reducing the interference of different base stations using the same frequency spectrum, thereby improving spectrum utilization efficiency and system throughput.
在上述实施例的基础上，在步骤101之前，还可以包括：On the basis of the above embodiment, before step 101, it can also include:
