Embodiment 1

[0654] In the first embodiment, the user equipment adopts PUCCH Format 3 to transmit ACK / NACK.

[0655] According to the current third-generation partnership program (3 rd Generation Partener Project (3GPP) Technical Specification (TS) 36.213 V10 defines that when PUCCH format 3 is used to transmit ACK / NACK, in an uplink subframe, the user equipment can transmit up to 20 bits of ACK / NACK. The bit number threshold is set to 20.

[0656] Currently, during carrier aggregation, up to 5 groups of carriers can be scheduled at the same time. According to the demand of business volume, when DSS technology is adopted, the downlink signal can be transmitted in the uplink frequency band of 5 groups of carriers. The uplink and downlink subframe ratio of the Time Division Duplex (TDD) system can be used for reference, and the subframes of part of the uplink frequency band can be configured for downlink transmission. Of course, other methods can also be used to configure the uplink resources ...

Embodiment 2

[0700] In the second embodiment, the user equipment uses PUCCH Format 1b with channel selection for transmission.

[0701] According to the current 3GPP TS 36.213 physical layer process version number defined as V10, when PUCCH Format 1b with channel selection is used to transmit ACK / NACK, the user equipment can transmit up to 4 bits of ACK / NACK in an uplink subframe, then the above preset The threshold of the number of bits is 4.

[0702] In the second embodiment, the following four options are provided:

[0703] The user equipment 301 combines at least two ACK / NACK to be sent, so that:

[0704] The combined at least two ACK / NACK occupies 4 bits, of which 2 bits are used to feed back the reception of the first signal sent on a carrier in the first frequency band, and the other 2 bits are used to send a carrier in the second frequency band Feedback on the reception of the second signal, or,

[0705] The combined at least two ACK / NACK occupies 4 bits, of which 2 bits are used to feed b...

Abstract

The present invention relates to the technical field of wireless communication, and in particular, to user equipment, network equipment and a method for transmitting confirmation information. Wherein, for at least one first ACK / NACK and at least one second ACK / NACK among the at least two ACK / NACKs to be sent on an uplink subframe, the user equipment shall, according to the first ACK / NACK first, the second The ACK / NACK comes after, or the second ACK / NACK comes first and the first ACK / NACK comes after. The network device can determine which of the at least two ACKs / NACKs received are used to feed back signals transmitted in non-traditional communication methods and which are used to feed back signals transmitted in traditional signal transmitted in the mode. Therefore, a feedback mechanism for confirming information is provided when the user equipment communicates in both the traditional communication mode and the non-traditional communication mode.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a user equipment, network equipment, and a transmission method of confirmation information. Background technique [0002] In order to ensure the reliability of communication transmission, a feedback retransmission method is introduced in the wireless communication system. That is, when the first communication device sends information to the second communication device, the second communication device determines whether the obtained information is correct through decoding verification, etc., and sends the judgment result to the first communication device. If the feedback information indicates that the second communication device cannot obtain the information sent by the first communication device, the first communication device needs to retransmit the previously sent information; otherwise, it is not required. The indication information fed back by the comm...
