Title:
UPLINK CONTROL INFORMATION TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/179222
Kind Code:
A1
Abstract:
Disclosed are an uplink control information transmission method and device, the method comprises: determining a feedback time, wherein the feedback time is used to instruct a terminal device to send uplink control information to a network device according to the feedback time; and sending the feedback time to the terminal device. By means of establishing a feedback mechanism between a network device and a terminal device, namely, the network device determines a feedback time, and sends the determined feedback time to the terminal device, so that the terminal device sends uplink control information to the network device according to the feedback time, thereby notifying the network device about whether downlink data has been correctly received, and effectively avoiding the problem of the waste of system resources caused by the network device having to re-send the downlink data to the terminal device due to not being able to determine whether the terminal device has correctly received the downlink data; moreover, the terminal device can also flexibly feed back the uplink control information according to the feedback time sent by the network device, thereby effectively enhancing the system robustness when an NR is independently deployed on an unlicensed frequency band.
