Abstract

This invention discloses a distribution method for code channel resource accessed by TD-CDMA, in which, a UE starts up an inbound authorization application to node B by E-RUCCH or E-PUCH, and node B applies a dispatch algorithm to appoint a spread spectrum code channel, its power and time slot to the UE according to the size of the inbound information block, radio resource and UE service grade condition and sends them to the UE by E-AGCH, the UE selects a suitable modulation mode and a transmission block and applies a speed rate match algorithm to upload data to node B on the spread spectrum code channel and time slot distributed by node B.

Description

technical field

[0001] The invention relates to a code channel resource allocation method for high-speed uplink packet access in a wireless communication system, especially in a time division code division multiple access wireless communication system. Background technique

[0002] First, let’s explain the English and Chinese corresponding to the English abbreviations to be used:

[0003] TPC: Transmitter Power Control transmission power control.

[0004] TFC: Transport Format Combination transmission format set.

[0005] TFCI: Transport Format Combination Indicator transport format set indication.

[0006] HSUPA: High Speed ​​Uplink Packet Access High-speed uplink packet access.

[0007] E-PUCH: E-DCH Physical Uplink Channel E-DCH physical uplink channel.

[0008] E-DCH: Enhanced Dedicated Channel Enhanced Dedicated Channel

[0009] E-HICH: E-DCH HARQ Acknowledgment indicator channel E-DCH HARQ acknowledgment indicator channel.

[0010] E-RUCCH: E-DCH Random Access Up...

Examples

Embodiment Construction

[0038] Taking the TD-SCDMA system as an example, the method for allocating code channel resources of the HSUPA technology E-PUCH in the time division code division multiple access system proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Fig. 2 is the flow chart of the PUCH resource allocation and use method of HSUPA of the present invention, mainly comprises the following steps:

[0040] Step 1: UE initiates an upload authorization application to Node B through E-RUCCH or E-PUCH, carrying the upload information block size, radio resources, UE service level and other conditions;

[0041]If the UE does not have the E-PUCH channel resources authorized by the Node B at this time, the UE needs to initiate a random access process, and send an uplink scheduling transmission request to the Node B through the E-RUCCH channel configured by the RNC; on the other hand, if the UE has been authorized The E-PUCH channe...
