Title:
ACKNOWLEDGEMENT INFORMATION TRANSMISSION METHOD, TERMINAL DEVICE, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029317
Kind Code:
A1
Abstract:
Provided are a method for sending and receiving acknowledgement information, a terminal device, a network device, and a system, wherein the sending method comprises: a terminal device receiving uplink scheduling information from a network device in a time unit n, the uplink scheduling information being further used to acquire a maximum number of first downlink data packets sent by the network device to the terminal device over a time period from a time unit n-k3 to time a unit n+k2; and the terminal device sending, on an uplink data channel of a time unit n+k1, acknowledgement information of the first downlink data packets to the network device according to the maximum number of the first downlink data packets. Thus, a base station and a terminal agree on the amount of acknowledgement information fed back by the terminal to the base station on a PUSCH of the time unit n+k1, such that when acknowledgement information is sent on the PUSCH and data is decoded by the base station, a data receiving error caused by the base station not knowing an actual amount of acknowledgement information sent by the terminal is prevented.
