Problems solved by technology

[0004] Since the base station has to stop and wait for the downlink HARQ-ACK feedback information after each data packet transmission, and the channel is idle during the waiting for the acknowledgment, no data is sent, so the throughput of the above method is very low

Embodiment Construction

[0031] Embodiments of the present invention provide a method for transmitting HARQ-ACK feedback information and related devices, so as to reduce uplink resources occupied by multiple downlink HARQ processes.

[0032] The related devices involved in the embodiment of the present invention include terminal equipment and a base station.

[0033] The above-mentioned terminal equipment and base station can be applied to a long-term evolution (LTE) system or an advanced long-term evolution LTE-A (LTE Advanced) system. Of course, the present invention can also be applied to other communication systems, as long as there are entities in the communication system that can send information, and there are other entities in the communication system that can receive information.

[0034] Figure 2a An exemplary application scenario of the above-mentioned terminal device and base station is given, and the base station 201 communicates with any number of terminals similar to the terminal devi...

Abstract

The present application relates to the field of communication technology, in particular to the transmission technology of HARQ-ACK feedback information. In a method for transmitting HARQ-ACK feedback information, a terminal device acquires downlink HARQ-ACK feedback information of each HARQ process in multiple HARQ processes; the terminal device feeds back multiple downlink HARQ-ACKs of the multiple HARQ processes Information is transmitted simultaneously on the same time-frequency resource. Through the solution provided by the embodiment of the present application, the downlink HARQ-ACK feedback information of multiple HARQ processes is simultaneously transmitted on the same time-frequency resource. Thus, the number of times the terminal equipment feeds back the downlink HARQ-ACK feedback information and the occupancy of uplink time-frequency resources by multiple downlink HARQ processes is greatly reduced, thereby reducing the power consumption of the terminal equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to the transmission technology of HARQ-ACK feedback information. Background technique [0002] In a communication system, a hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request) manner may be used for error control. [0003] The downlink HARQ uses the stop-and-wait mechanism to send data: please refer to Figure 1a , the base station device sends a data packet ( Figure 1a 0-4 in is the data packet identifier), it stops and waits for the downlink HARQ-ACK feedback information (ACK or NACK) of the terminal equipment. Wait until the feedback information from the terminal device is received before sending the data packet. For example, the base station sends data packet 0, and then stops and waits for the terminal equipment to feed back the downlink HARQ-ACK feedback information for data packet 0 (ie Figure 1a ACK0 in ), wait until ACK0 is received, an...
