Embodiment Construction

[0027] As described in the background art, TDD (Time Division Duplexing, Time Division Duplexing) mode, one of the two basic duplexing systems, has received more and more attention under the background of increasing demand for bandwidth in broadband mobile communications. In a TDD system, uplink and downlink transmission use the same frequency resource, and uplink / downlink signals are transmitted on different time slots. Common TDD systems include 3G (3rd Generation, third generation mobile communication system) TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system and 4G (4th Generation, fourth In the TD-LTE (TD-SCDMA Long Term Evolution, TD-SCDMA long-term evolution) system, the division of uplink and downlink time slots is static or semi-static, and the usual practice is to base The approximate business ratio determines the unified uplink and downlink time slot ratio and keeps it unchanged. This is a relatively simple approach in the context of large ma...

Abstract

Disclosed are an inter-cell resource coordination method and device. By applying the technical solution in the embodiments of the present invention, resource scheduling and protection resource block reservation are performed according to the acquired resource scheduling information and up/downlink configuration information about a surrounding cell, so that an adjacent cell can select a suitable resource allocation manner, suppressing inter-cell interference, especially up/downlink signal interference.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for inter-cell resource coordination. Background technique [0002] The basic idea of ​​inter-cell interference coordination is to limit the use of edge user resources through inter-cell coordination, including limiting which time-frequency resources are available, or limiting their transmit power on certain time-frequency resources, such as figure 1 As shown in FIG. 2 , it is a schematic diagram of frequency soft multiplexing technology in the prior art, and the purpose of avoiding and reducing interference and ensuring edge coverage rate is achieved by this solution. The inter-cell interference coordination may adopt a static method or a semi-static method. [0003] The basic idea of ​​static interference coordination is to plan in advance the frequency available to each cell edge user or which PRBs (Physical Resource Block, Physical Resou...
