The problem of interference between the base stations having extended coverage requirements and the user equipment they serve is low due to interference between them.

 The method for resource allocation described above will be described in detail below through a specific embodiment. Referring to FIG. 4, the method for resource allocation in this embodiment includes:

 401: The central network controller acquires a channel quality parameter of the first base station.

 Exemplarily, a central network controller is used to allocate resources to a base station. The channel quality parameter of the base station is any one or several parameters that can determine the channel quality of the base station, for example, the signal to noise ratio of the downlink pilot signal of the first base station. The better the channel quality of the base station, the more the number of restricted subframes of the base station in one subframe cycle.

 402: The central network controller determines, according to a channel quality parameter of the first base station, a number of restricted subframes of the first base station in one subframe cycle period;

 Exemplarily, the better the channel quality of the base station, the more the number of restricted subframes of the base station in one subframe cycle period.

 403: randomly select, as a restricted subframe, a subframe that is equal to the number of restricted subframes of the first base station in one subframe period;

 404: The central network controller selects, from the RRS information, a subframe type corresponding to the set of the limited resources of the first base station;

 For example, referring to Table 1, if the set of constrained resources of the first base station determined in step 403 is to restrict the use of the data channel in the physical layer channel, then the selected one corresponding to the set of constrained resources of the first base station is selected. The subframe type is type 1.

405: The central network controller is configured according to the restricted subframe of the first base station and the restricted base of the first base station. The subframe type of the frame and the subframe cycle period acquire the RRS pattern of the first base station; for example, the restricted subframe of the first base station determined in step 402 is the first, second, and fourth subframes, which are obtained in step 404. The subframe types of the first, second, and fourth subframes are type 1, type 1, and type 2, respectively, and the subframe period of the first base station is 8 subframes, and type 0 indicates that the base station limited resource set is empty. The set (ie, the resource is not limited), the RRS pattern is represented by a vector, then the obtained RRS pattern of the first base station can be expressed as: 11020000.

 406: The central network controller sends the RRS pattern of the first base station to the first base station.

407: The first base station limits, in the restricted subframe of the first base station, the limited resources in the set corresponding to the subframe type of the restricted subframe according to the RRS pattern;

 408: The central network controller sends the RRS pattern to the second base station, where there is downlink interference between the second base station and the first base station;

 Exemplarily, the second base station may include one or more base stations that have downlink interference with the first base station. Since the interference between the first base station and the second base station is small in the restricted subframe of the first base station, the central network controller may send the RRS pattern of the first base station to the second base station, so that the second The base station learns the restricted subframe of the first base station.

 409: The second base station carries the RRS pattern on the high layer signaling or the command of the high speed shared channel HS-SCCH, and sends the RRS pattern to the user equipment served by the second base station;

 Exemplarily, the step may enable the user equipment served by the second base station to learn the restricted subframe of the first base station.

 410: The second base station communicates with the user equipment served by the second base station in the restricted subframe of the first base station according to the RRS pattern.

 Optionally, in HetNet, the first base station refers to a macro base station, and the second base station refers to a micro base station. Exemplarily, the second base station may schedule large block length data or send control signaling to the user equipment served by the second base station in the restricted subframe of the first base station.

Before the user equipment served by the second base station communicates with the second base station, it is generally required to determine the quality of the control channel of the second base station. In this case, it may be determined by detecting only the control channel quality of the second base station in the restricted subframe of the first base station. As a result of the judgment, since the control channel quality of the second base station is better in the restricted subframe of the first base station, using the method to detect the control channel quality of the second base station can improve the user equipment served by the second base station and the second Communication with the base station; or, in conjunction with Table 1, when the RRS pattern of the first base station received by the user equipment served by the second base station is 22200000, the interference cancellation can be performed in the first three subframes according to the RRS pattern (Interference Cancellation, referred to as IC ) to further reduce interference from the first base station.
