Embodiment 1

[0129] Taking the Time Division Duplex Synchronous Code Division Multiple Access (LCR-TDD) system with a chip rate of 1.28Mcps as an example, this paper further introduces the realization scheme of transmitting the response signal by using the common channel.

[0130] The hypothetical conditions in this embodiment are described as follows: it is assumed that the transmission time interval of the uplink code combination transmission channel supporting the hybrid automatic repeat technology is 5 milliseconds.

[0131] Assume that there are two user terminals transmitting uplink data in the kth subframe. Among them, the first user terminal is assigned N UL，1 Uplink code combination transport channels are used to transmit uplink data packets, and these uplink CCTrCHs all support HARQ technology, that is, the parameter N UL，1 The value is 2, and it is assumed that the two uplink CCTrCHs are respectively mapped to the channel code with the spreading sequence number 0 and the channe...

Abstract

A method for transmitting response signal by down response public channel transmission, which contains Node B determining transmission time of response signal, Node B numbering transmission channel, Node B determining the transmitted content and making coding process, Node B interlacing data bit flow then mapping to physical channel to transmit. Said invention provides a transmission method to ACK / NAC response signal, method for determining the mapping relationship between down ACK / NAC response signal and upper CCTrCH without transmitting upper CCTrCH number to reduce transmission signaling load.

Description

technical field [0001] The present invention relates to the link self-adaptation technology in the wireless communication system, in particular to the transmission and reception method of the response signal in the automatic repeat request technology. Background technique [0002] The 3rd Generation Partnership Project (abbreviated as 3GPP) is a technical standardization organization implementing the 3rd generation mobile communication system, wherein the 3rd generation mobile communication technical standards include frequency division duplex (FDD) and time division duplex (TDD) mode technical standards. Since its inception, 3GPP has announced Release 99, Release 4, and Release 5, three versions of technical standards for third-generation mobile communication systems. Among them, the Release99 version was announced in October 1999, mainly including the third-generation mobile communication system technical standards of 3.84Mcps frequency division duplex (FDD) and time divis...
