Problems solved by technology
[0009] Multiple SRI channels are reserved for each user equipment. When the user equipment does not need to feed back response information to the base station, the multiple SRI channels reserved for the user equipment are idle and cannot be used by other user equipment, resulting in a shortage of bandwidth resources. The utilization rate is low, resulting in a great waste of limited bandwidth resources

The embodiment of the invention discloses a method and device for transmitting and receiving a response message and a scheduling request indication (SRI) message. The method comprises the following steps of: acquiring a first resource corresponding to a state of a response message to be transmitted, wherein the first resource comprises an acknowledgement character (ACK) channel and a message sign, the ACK channel comprises L sub channels, and the first resource corresponding to the state of the response message to be transmitted comprises a first ACK channel and a first message sign; and changing the first resource corresponding to the state of the response message to be transmitted into a corresponding second resource according to a preset change rule and the state of an SRI message to be transmitted, and transmitting a third resource on a second channel in the second resource, wherein the second resource comprises the second channel and a second message sign, the third resource comprises the first message sign and / or the second message sign, and the second channel at least comprises a sub channel which is same as that of the first ACK channel. According to the embodiment of the invention, the bandwidth resource use ratio can be improved and bandwidth resources can be saved.
Description
technical field [0001] The invention relates to communication technology, in particular to a method and device for transmitting and receiving response information and scheduling request indication information. Background technique [0002] In Hybrid Automatic Repeat Request (HARQ for short) technology, after the data sender sends data to the data receiver, the data receiver needs to feed back the response information to the data sender, and confirm to the data sender whether it is received correctly. the data it sends. Specifically, the value of the response information may be an acknowledgment (Acknowledgment, hereinafter referred to as: ACK), a negative-acknowledgement (hereinafter referred to as: NACK), and a discontinuous transmission (Discontinuous Transmission, hereinafter referred to as: DTX). Among them, ACK indicates that the data is received correctly, NACK indicates that the data is received incorrectly, and DTX indicates that the data has not been received. The...
