Problems solved by technology

In the prior art, in the unlicensed frequency band, the uplink control information is generally sent according to the agreed period, and the downlink data sent according to the period may conflict with the time resource of the downlink burst data sent by the base station

Embodiment Construction

[0029] figure 1 Example of FIG time resources of the target carrier (or time domain resources) on a non-licensed spectrum occupancy. Before the base station sends downlink data, the process needs to be LBT, monitor whether the channel is idle. After the base station obtains channel resource, the base station starts to transmit downlink data. From figure 1 As can be seen, the base station needs to transmit downlink data bursts in consecutive 10 subframes (i.e., downlink burst 10ms), assumed that the terminal in the prescribed period, the fifth will be at the 10 th sub-frame control information of the uplink frame transmission ( figure 1 In an example SR) In this case, the transmission time of uplink control information, resource conflict occurs and time resource for transmitting the downlink data.

[0030] In one example, the terminal may transmit an SR or not the frame period in the fifth sub-CSI (CSI can be divided into periodic and aperiodic CSI CSI), the base station continues...

Abstract

The embodiment of the invention provides a method for sending uplink control information and a terminal. The method comprises the following steps: the terminal determines a first time resource for sending first uplink control information; and if the first time resource comprises a downlink time resource, the terminal device sends the first uplink control information on a third time resource, the third time resource being after the downlink time resource. The embodiment of the invention also provides another method for sending the uplink control information and a base station.

Description

[0001] This application is filed International Patent PCT 2016 years 03 22 February Application PCT / CN2016 / 077011 entering the Chinese national phase of Chinese Patent Application No. 2016800649762, entitled "Method for transmitting uplink control information, the terminal and base station" the divisional application. Technical field [0002] Example The present application relates to wireless communications, and more particularly, to a method for transmitting uplink control information, and a base station for a terminal. Background technique [0003] Long term evolution (Long Term Evolution, LTE) system, uplink control information (uplink control signaling may also be referred to) includes a scheduling request (Scheduling Request, SR), channel state information (Channel StateInformation, CSI), hybrid automatic retransmission request (Hybrid Automatic Repeat reQuest, HARQ) during confirmation (Acknowledgement, ACK) / negative acknowledgment (negative acknowledgment, NACK) info...
