Data processing method and device for channel selection 1bcs confusion information in pucch format 1b

Abstract

The embodiment of the invention provides a data processing method and device for obfuscating data of PUCCH (Physical Uplink Control Channel) format 1b with channel selection 1bcs. The method comprises the following steps: receiving a downlink data reception state table fed back by a terminal using PUCCH format 1b with channel selection 1bcs; receiving a channel quality indicator (CQI) reported by the terminal; determining a modulation and coding strategy 1 (MCS1) level corresponding to the CQI; when detection indicates that a hybrid automatic repeat request (HARQ) is obfuscating data ANY, adjusting the MCS1 level according to a previous HARQ of the obfuscating data ANY, wherein the previous HARQ comprises acknowledgement (ACK), negative acknowledgement (NACK) and discontinuous transmission (DTX); and processing the obfuscating data ANY as the ACK or the NACK according to the adjusted MCS2 level. Through adoption of the data processing method and device, extra repeat of downlink data can be avoided, and the waste of network resources is avoided.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a data processing method for channel selection 1bcs confusion information of PUCCH format 1b and a data processing device for channel selection 1bcs confusion information of PUCCH format 1b. Background technique [0002] LTE TDD, also known as Time Division Long Term Evolution (TD-LTE) in China, is a time division duplex wireless technology. [0003] In the R10 version, the LTE TDD system introduces carrier aggregation (CarrierAggregation, CA) technology, by aggregating two or more carriers together, and then performing data transmission on each channel format to improve data transmission capabilities. [0004] In order to support carrier aggregation, the LTE TDD system has added a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) hybrid automatic repeat request (Hybrid Automatic RepeatreQuest, HARQ) feedback method, that is, PUCCH for...

Problems solved by technology

[0008] The processing result obtained by this method of processing the confusion information ANY often deviates from the HARQ actually fed back by the terminal. When the HARQ fed back by the terminal is the confirmation information ACK, the confusion information ANY is treated as the non-acknowledgment information NACK, and the corresponding downlink data is processed. For retransmission, when the HARQ feedback from the terminal is non-confirmation information NACK, the confusion information ANY is treated as confirmation information ACK, so that no retransmission operation is performed, which leads to the fact that the downlink data that should have been retransmitted is not retransmitted. The downlink data that should be retransmitted is retransmitted, which not only results in delayed arrival of downlink data, but also wastes network resources due to additional retransmissions
