Embodiment Construction

[0058] Taking the TD-SCDMA system as an example, the method for processing the data and signaling transmission 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.

[0059] method one:

[0060] Setting: TFC: 6bits;

[0061] RSN: 2bits;

[0062] HARQ entry number: 3bits

[0063] The signaling is 11bits, using Convolutional Coding (1 / 3 or 1 / 2) convolutional coding method;

[0064] Data: 30bits;

[0065] Spreading factor: The spreading factor of the data and signaling part is different; the CRRI of E-AGCH can be indicated as the code tree node allocated to the user.

[0066] The E-PUCH burst structure adopts such as figure 2 The structure shown, the flow of data and signaling transmission is as follows Figure 4 shown.

[0067] The part of TFC, RSN, and HARQ sequence number adopts the fixed spread spectrum method of SF=16, ...

Abstract

This invention discloses a transmitting method for high speed up-line packet access data and signaling of the TD-CDMA system, in which, the signaling transmission includes: a UE carries out channel code to transmission format set, re-transmission list number and mixed automatic re-transmitted required process sequence number and scrambles the coded signaling then interlaces the signaling then to match rate to the signaling according the rate match mode fixed by a punch template and maps it to a physical channel.

Description

technical field [0001] The invention relates to a method for transmitting data and signaling 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] E-PUCH: E-DCH Physical Uplink Channel E-DCH physical uplink channel. [0007] E-DCH: Enhanced Dedicated Channel Enhanced Dedicated Channel [0008] E-HICH: E-DCH HARQ Acknowledgment indicator channel E-DCH HARQ acknowledgment indicator channel. [0009] E-AGCH: E-DCH Absolute Grant Channel E-DCH absolute grant channel. [0010] TBS: Transport Block Set transmissi...
