Problems solved by technology

But its disadvantage is that signaling can only be obtained after demultiplexing, that is, the transmission delay of signaling in this way is relatively large;
[0033] 4) A new, independent physical channel is used to carry uplink signaling, that is, a separate spreading codeword is required to transmit uplink signaling; this method is also possible for HCR-TDD, but in HCR-TDD The uplink codeword is limited. This method will increase the uplink interference (PAR), increase the transmit power margin and implementation complexity of the terminal (UE)

Embodiment Construction

[0070] According to the latest specification 3GPP TS25.221v5.5.0, in the HCR-TDD system, there are still 72 unused bits in the HS-SICH, so this invention proposes that when the UE has the HS-SICH uplink channel, use the HS-SICH channel The reserved bits in are used to convey the scheme of uplink signaling required for uplink channel enhancement.

[0071] At present, the uplink channel enhancement of HCR-TDD has just started to be discussed, and the possible signaling and the performance requirements of the signaling have not been determined, so the 72 reserved bits may not meet the performance requirements of the possible signaling. From the analysis of 1.1, it can be seen that the CQI field in the HS-SICH has an over-protected coding gain, so the present invention also proposes to use a puncture method, that is, to delete some bits in the coded CQI sequence, and use these punctured bits to combine with the reserved Bits are used together to transmit the scheme of uplink signa...

Abstract

A method for transferring up signaling to intensify up signaling channel by high speed shared information channel HS-SICH in 3.84Mcps short rate time division duplexing communication system, which contains coding N bit up signaling by (N, n) group code to generate N bit sequence, generating 72 bit sequence to N bit sequence after 72-N bit cyclic redundancy check, multicomplexing generated 72-N bit sequence and coded CQI and ACK / NACK to generate HS-SICH loaded data bit. Said invention fully utilizes reserved resource in current system to realize new function with better backward compatibility and reduce the complexity of using UE end to code and Node B to decode by adopting existing standard coding mode.

Description

technical field [0001] The present invention relates to code division multiple access (abbreviated as CDMA) mobile communication system, specifically in 3.84Mcps high-speed time division duplex code division multiple access mobile communication system (abbreviated as HCR-TDD), the uplink signal used for uplink channel enhancement command transmission method. 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 technology standard includes Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes. Since its establishment, 3GPP has announced in October 1999 the third-generation mobile communication system technical standards, which mainly include 3.84Mcps Frequency Division Duplex (FDD) and Time Division Duplex (HCR-TDD), referred to as Release 99; in 2000 In 2018, the technica...
