Embodiment

[0080] An embodiment of the present invention is described with reference to the drawings.

[0081]Figure 5(a) and (b) show an example of allocation of mixed radio resources under centralized control composed of two cells. The RNC controls two cells (cell 1 and cell 2), and the characteristic codes of each cell are fixedly assigned by the RNC. An 8×6 time-frequency block resource should basically determine the allocation of uplink channels and downlink channels according to business requirements. That is to say, there are 8 time slots and 6 sub-bands in each frame. According to the above-mentioned mixed channel allocation scheme, fixed and variable channel allocation ranges and positions of uplink and downlink switching points. The range of fixed downlink time slots is [1, 2], and the range of frequencies is [1, 6]; the range of fixed uplink time slots is the eighth time slot, and the range of frequency j is [1, 6]. The range of variable time slot i is [3, 7]; the range of ...

Abstract

The method includes following steps: the wireless network controller allocates and manages the wireless channel resources; a mixed allocation mode combining the fixed-allocation with dynamic allocation is used to provide channels for base station and mobile station. The invention in use for channel allocation in TDD mobile communication system adopts central control and dispatch for wireless resources to improve the utilization rate of resources and the relevant transmission efficiency, and meanwhile to reduce the inter-cell interference and intra-cell interference.

Description

technical field [0001] The invention relates to allocation and transmission technology of wireless channel resources in a mobile communication system, in particular to a method for channel division of a cell in a time division duplex (abbreviated as TDD) cellular mobile communication system. Background technique [0002] The cellular mobile communication system needs to allocate wireless channels to each base station and mobile station so that they can complete uplink and downlink service transmission. The mobile communication system based on Time Division Duplex (TDD) can flexibly allocate uplink and downlink channels according to service requirements, and realize effective transmission of symmetric and asymmetric services. [0003] The goal of channel allocation is to maximize the use of wireless channel resources and transmit data signals at high speed with as little interference as possible. In order to control the resources of the mobile communication system, the use o...
