Embodiment

[0080] Referring to the accompanying drawings, an embodiment of the present invention is given below.

[0081] Figure 6 (a), (b), (c) shows an example of centralized control and allocation of mixed radio resources composed of three cells. The RNC controls 3 cells (cell 1, cell 2 and cell 3), and the characteristic codes of each cell are fixedly allocated in advance by the RNC. There is an 8×6 time-frequency block resource, and the uplink channel and downlink channel allocation should be basically determined 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 the fixed downlink time slot is the first time slot, and the frequency range is [1, 6]; the range of the fixed uplink time slot is the second time slot, and the frequency range of j is [1, 6]...

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. When the invention uses different orthogonal code sequences to allocate different cell, the resources of time slot and frequency can be jointly allocated to each cell. In TDD mobile communication system, the allocation above can reduce the interference between cells, and also reduce the interference between up stream signals and down stream signals.

Description

technical field [0001] The present invention relates to channel resource allocation and transmission technology in a mobile wireless communication system, in particular to a method for cell channel division in a Time Division Duplex (abbreviated as TDD) mobile communication system. Background technique [0002] In a mobile communication system, channel allocation is a part of wireless resource allocation, which is related to the occupied resources of each cell, service flow, and inter-cell and intra-cell interference. The cellular mobile communication system needs to allocate wireless channel resources to each base station and mobile station in the network so that they can complete uplink and downlink service transmission. The TDD-based mobile communication system 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...
