Embodiment Construction

[0036] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] The basic idea of ​​the present invention is: when the isolation degree of UEs in different channels is good enough, the HS-PDSCH code channel resources can be reused to improve the system capacity in a multi-channel environment.

[0038] Concrete, the method for air separation HSDPA in the present invention comprises:

[0039] Select the strong channel of each UE according to the uplink DPCH channel estimation, and determine the priority queue according to the scheduling priority of each UE;

[0040] According to the priority queue, allocate HS-PDSCH code channel resources for each UE on the strong channel, and any HS-PDSCH code channel resource in the HS-PDSCH resource pool is allowed to be allocated to N different channels Above, the N is a natural number...

Abstract

The invention discloses a method for space division of HSDPA in a multi-channel system. The method comprises the steps of: selecting a strong channel of each UE according to an uplink DPCH signal channel estimation, and determining a priority queue according to a scheduling priority of each UE; allocating an HS-PDSCH code channel resource to the UE on the strong channel of each UE according to the priority queue, wherein any S-PDSCH code channel resource in an HS-PDSCH resource pool is allowed to be allocated to N different channels, and the N is a natural number less than or equal to a preset multiplexing coefficient; and processing and transmitting data according to an resource allocation result by a downlink. The method for the space division of the HSDPA in the multi-channel system can greatly improve the capacity of the multi-channel system without additional baseband resources and resulting in frequent switching among cells.

Description

technical field [0001] The invention relates to high-speed downlink packet access (HSDPA) technology, in particular to a method for space division HSDPA in a multi-channel system. Background technique [0002] Utilizing the multi-channel characteristics of the TD-SCDMA system can well solve the problem of indoor coverage. In the current network construction, the indoor coverage systems of many office buildings and office buildings are based on multi-channel communities, such as figure 1 As shown, this indoor coverage system has the following characteristics: [0003] 1. A multi-channel community covers the entire office building, and each channel covers several floors; [0004] 2. The isolation of the coverage area of ​​each channel is better. Generally, the isolation between two adjacent floors is about 12 or 13dB. [0005] Because the spectrum resources of TD-SCDMA are relatively limited, how to improve the capacity of indoor coverage is very important. In order to imp...
