Problems solved by technology

[0006] For sending absolute authorization through E-AGCH, UE judges whether it belongs to the UE's scheduling through E-RNTI (Radio Network Temporary Identity). In the allocation of E-RNTI, there are two types of E-RNTI: primary E-RNTI And secondary E-RNTI, for secondary E-RNTI, generally for multiple UEs, the power setting problem at this time is not specified in the agreement, if the power setting is improper, the bit error rate of E-AGCH will increase, Poor control of UE by Node B, resulting in lower control efficiency of uplink resources

Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] The UE appearing in the present invention refers to the UE configured with the HSUPA service.

[0018] like figure 1 As shown, the method for reducing the absolute authorized channel bit error rate of the enhanced dedicated channel of the present invention includes: step S102, establishing a wireless data link supporting the enhanced dedicated channel between the base station and one or more user equipments; step S104, the base station receives After receiving the scheduling request information from one or more user equipments, the base station determines to send the same absolute authorization command to one or more user equipments, and calculates the time required for sending the absolute authorization command to each of the one or more user equipments. Power; step S106, the base station sends the absolute grant command ...

Abstract

The invention provides a method for lowering the error code rate of an absolute authorization channel of an appropriative enhancement channel and comprises the following steps: step one, a wireless data link supporting the appropriative enhancement channel is built between a base station and one or more user equipments; step two, after the base station receives schedule request information from the one or more user equipments, the base station determines to send the same absolute authorization command to the one or more user equipments, and the power required for sending the absolute authorization command to each of the one or more user equipments is respectively computed; step three, the base station uses the largest value in the computed power required for sending the absolute authorization command to each user equipment as the power of the absolute authorization channel of the appropriative enhancement channel, and sends the absolute authorization command to the one or more user equipments. The method of the invention can effectively reduce the error code rate of E-AGCH and improves the schedule controlling efficiency of Node B to UE.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) wireless communication system for reducing the absolute grant channel (E-AGCH, E-DCH Absolute GrantChannel) error bit of an enhanced dedicated channel rate method. Background technique [0002] The third generation (3G) wireless mobile communication is in constant evolution and changes, constantly introducing new requirements to achieve low cost and high performance, in the fifth version (R5, Release 5) and sixth version (R6, Release 6 ) respectively introduced HSDPA (High Speed ​​Downlink Packet Access) and HSUPA (High Speed ​​Uplink Packet Access), the main purpose of which is to improve the utilization of wireless spectrum and improve the overall performance of the system. [0003] HSUPA is an enhancement technology for uplink transmission capability of WCDMA system. It mainly introdu...
