Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The present invention proposes a method for dynamically adjusting the DPCH repetition period according to the system load in the HSDPA system. Based on factors such as cell load, cell capacity, and system performance, the repetition cycle is dynamically configured according to the current load of the cell: when code channel resources are congested , increase the configuration value of the repetition period, so that more users can share the accompanying DPCH, and increase the system capacity as much as possible; when there are many idle resources of the code channel, reduce the configuration value of the repetition period to achieve inner loop power control performance optimal. Accordingly, a dynamic balance between system capacity and system performance is realized.

[0025] Each HSDPA user needs to have DPCH to carry informat...

Abstract

The invention discloses a method for dynamically adjusting the repeated period of an associated special physical channel, applied in a high speed descending packet access system. The method comprises: in the initialization, defaulting the value of the repeated period of an associated special physical channel; attaining the resource block trigger threshold value and the resource idle trigger threshold value of the associated special physical channel; judging the left amount of the resource of the associated special physical channel, if the left amount is lower than the resource block trigger threshold value, selecting part of the associated special physical channel and increasing the repeated period of the user of the channel, or else, judging if the left amount is higher than the resource idle trigger threshold value, if the left amount is higher than the resource idle trigger threshold value, selecting part of the associated special physical channel and reducing the value of the repeated value of the user of the channel. The inventive method dynamically distributed the repeated period of a region according to the prior load, to realize the dynamic balance between the system capacity and performance.

Description

technical field [0001] The present invention relates to the accompanying dedicated physical channel (Dedicated Physical Channel, hereinafter referred to as DPCH) in the High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access, hereinafter referred to as HSDPA) system, specifically, relates to a kind of dynamic adjustment HSDPA accompanying DPCH The method of repeating the cycle. Background technique [0002] The HSDPA technology is introduced in the Release 5 protocol of the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology to improve the throughput of downlink services. Each HSDPA user needs an uplink accompanying DPCH and a downlink accompanying DPCH to carry information such as transmit power control (Transmit Power Control, hereinafter referred to as TPC) bits. Each accompanying DPCH needs to occupy a code resource with a spreading factor (Spreading Factor, SF for short) of 16. In the TD-SCDMA wireless access technology, the ...
