Method, System, Terminal and Base Station for Transmitting Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) Feedback Information

摘要

The embodiments of the present document disclose a transmission method and system for HARQ-ACK feedback information, a terminal and a base station, herein the transmission method includes: determining, by a base station, a PUCCH corresponding to a terminal according to a preset transmission policy, herein the transmission policy is: transmitting, by the base station, PUCCH indication signaling to the terminal, the indication signaling carrying information of one PUCCH of preset N PUCCHs, the one PUCCH being a PUCCH corresponding to the terminal; or determining a PUCCH corresponding to the terminal according to preset resources; or determining a preset terminal-specific PUCCH to be a PUCCH corresponding to the terminal; and receiving by the base station, HARQ-ACK feedback information through the determined PUCCH.

主权项

1. A transmission method for Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback information, comprising: when a base station determines that a terminal is in a coverage-enhanced scenario,
determining, by the base station, a Physical Uplink Control Channel (PUCCH) corresponding to the terminal according to a preset transmission policy, wherein the transmission policy is: transmitting, by the base station, PUCCH indication signaling to the terminal, the indication signaling carrying information of one PUCCH of preset N PUCCHs, the one PUCCH being a PUCCH corresponding to the terminal, wherein N is a positive integer greater than or equal to 2; or determining a PUCCH corresponding to the terminal according to preset resources; or determining a preset terminal-specific PUCCH to be a PUCCH corresponding to the terminal; and receiving, by the base station, HARQ-ACK feedback information from the terminal through the PUCCH corresponding to the terminal.
