Problems solved by technology

[0004] In the process of implementing the present invention, the inventor found that at least the following defects exist in the prior art: since there are many ACK / NACK responses to be fed back in the LTE-A system, the probability of the ACK / NACK information to be transmitted is 00 is relatively low. High, and at this time the base station needs to retransmit the data of all scheduled downlink subframes, resulting in unnecessary retransmissions and reducing the downlink throughput

Embodiment Construction

[0036] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0037] In the LTE-A system supporting carrier aggregation technology, the frequency spectrum of two or more component carriers can be aggregated together to obtain wider transmission bandwidth. The LTE-A system can serve both LTE terminal equipment and LTE-A Terminal Equipment. Among them, an LTE terminal device can only access one of the component carriers for data transmission and reception, while an LTE-A terminal device can simultaneously access one or more component carriers for data transmission and reception according to its capabilities and service requirements, and the simultaneous access The number of uplink and downlink component carriers may not be equal. In the carrier aggregation technology, each component carrier corresponds to an independent HARQ process, so that each component carrier has its ow...

Abstract

The embodiments of the present invention disclose an information processing method and apparatus in multi-carrier mode, wherein, the method includes: multiple acknowledgment responses are grouped according to grouping information, and multiple acknowledgment response groups are generated; the acknowledgement information to be transmitted which is generated by at least one acknowledgement response group is multiplexed with independent channel quality indicator information, the uplink feedback information generated by multiplex is transmitted to a base station via at least one channel quality indicator channel. The terminal apparatus includes a grouping module and multiplexing module, and the embodiments of the present invention also provide a base station. The embodiments of the present invention enable that multiple ACK / NACK information can be multiplexed with channel quality indicator (CQI) information flexibly and efficiently and transmitted on multiple CQI channels allocated for CQI information, the unnecessary information retransmission is reduced and the downlink throughput is improved.

Description

technical field [0001] Embodiments of the present invention relate to mobile communication technologies, and in particular to an information processing method and device in a multi-carrier mode. Background technique [0002] In a Long Term Evolution (hereinafter referred to as: LTE) system and a Long Term Evolution-Advanced (hereinafter referred to as: LTE-A) system, a Hybrid Automatic Repeat Request (Hybrid Automatic Repeat Request; hereinafter referred to as: HARQ) technology to reduce data transmission delay and obtain higher data transmission rate. In HARQ technology, the data receiver needs to feed back response information to the data sender, including Acknowledgment (hereinafter referred to as: ACK) / Negative- Acknowledgment; hereinafter referred to as: NACK) information to help confirm whether the data is received correctly. In addition, the terminal device needs to feed back Channel Quality Indicator (CQI) information to the base station to report the downlink chann...
