Embodiment 1

[0052] Figure 4 is a flowchart of a method for sending HARQ response information according to an embodiment of the present invention, as shown in Figure 4 As shown, the sending method of the hybrid automatic repeat request response information includes:

[0053] S402: When the terminal is configured to transmit HARQ-ACK response information using PUCCH format 3, and the HARQ-ACK response information is transmitted on the PUSCH, the terminal determines the number of downlink subframes in which the serving cell feeds back the HARQ-ACK response information;

[0054] S404: The terminal determines the number of coded modulation symbols required to send the HARQ-ACK response information according to the determined number of downlink subframes;

[0055] S406: The terminal maps the HARQ-ACK response information to be sent to the PUSCH of the specified uplink subframe according to the number of coding and modulation symbols for sending.

[0056] Regardless of whether the terminal i...

Embodiment 2

[0083] exist Figure 3-9 On the basis of the above, this embodiment provides a preferred sending device of HARQ response information to implement the above method. The sending device of HARQ response information can be located in a terminal, such as Figure 10 As shown, the above-mentioned sending device of HARQ response information includes:

[0084] The first determination module 100 is configured to determine the number of downlink subframes in which the serving cell feeds back the HARQ-ACK response information when the terminal is configured to transmit HARQ-ACK response information using PUCCH format 3, and the HARQ-ACK response information is transmitted on the PUSCH number;

[0085] The second determination module 102 is connected in communication with the first determination module 100, and is used to determine the number of coded modulation symbols required to send the HARQ-ACK response information according to the determined number of downlink subframes;

[0086] T...

Abstract

The present invention provides a method and device for sending hybrid automatic repeat request response information, wherein the above method includes: when configuring the terminal to transmit HARQ-ACK response information using the uplink physical control channel PUCCH format 3, the HARQ-ACK response information is transmitted in the uplink When transmitting on the physical shared channel PUSCH, the terminal determines the number of downlink subframes for which the serving cell feeds back the HARQ-ACK response information, and the terminal determines the number of coding and modulation symbols required to send the HARQ-ACK response information according to the determined number of downlink subframes The number; the terminal maps the HARQ-ACK response information to be sent to the physical uplink shared channel PUSCH of the specified uplink subframe according to the number of coded modulation symbols for transmission. The present invention solves the problem that the existing HARQ-ACK response information transmission method will transmit invalid HARQ-ACK response information when the uplink and downlink configurations of the serving cell are different in the related art, thereby improving the performance of the HARQ-ACK response information and improving the performance of the HARQ-ACK response information. data performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending Hybrid Automatic Repeat Request-ACK (HARQ-ACK for short) information. Background technique [0002] The radio frame (Radio Frame) in the long-term evolution (Long Term Evolution, referred to as LTE) system includes a frequency division duplex (Frequency Division Duplex, referred to as FDD) mode frame structure and a time division duplex (Time Division Duplex, referred to as TDD) mode frame structure. Such as figure 1 As shown, in the frame structure of FDD mode, a wireless frame of 10 milliseconds (ms) is composed of twenty slots (slots) with a length of 0.5 ms and numbered 0 to 19, and slots 2i and 2i+1 A subframe (subframe) i (wherein, 0≤i≤9) with a length of 1 ms, such as figure 2 As shown, in the frame structure of TDD mode, a 10ms wireless frame is composed of two half frames (half frame) with a length of 5ms, and a half frame includes fi...
