Method for transmitting feedback information, terminal equipment and base station
First Claim
1. A method for transmitting feedback information, comprising:
- receiving, by terminal equipment, a first signaling transmitted by a base station, the first signaling being configured to indicate K first Physical Uplink Control Channel (PUCCH) resource(s), wherein K is a positive integer;
in a first downlink subframe set, respectively receiving, by the terminal equipment, data on licensed carrier(s) and unlicensed carrier(s) which are aggregated, determining N-bit feedback information for the licensed carrier(s), and determining M-bit feedback information for the unlicensed carrier(s), wherein M is an integer more than or equal to 0, N is an integer more than or equal to 0, and at least one of M and N is not 0;
judging, by the terminal equipment, whether M is more than 0 or not; and
when M is more than 0, transmitting, by the terminal equipment, the M-bit feedback information and the N-bit feedback information on L first PUCCH resource(s) in the K first PUCCH resource(s) in a first uplink subframe, or, transmitting, by the terminal equipment, the N-bit feedback information on at least one second PUCCH resource and transmitting the M-bit feedback information on L first PUCCH resource(s) in the K first PUCCH resource(s) in a first uplink subframe, wherein L is a positive integer less than or equal to K, and the at least one second PUCCH resource is determined according to Downlink Control Information (DCI) configured for scheduling data transmission on the licensed carrier(s),wherein the first downlink subframe set comprises all downlink subframes corresponding to the first uplink subframe for transmitting the feedback information.

Abstract
The disclosure discloses a method for transmitting feedback information, terminal equipment and a base station. The method includes that the terminal equipment receives signaling indicative of Physical Uplink Control Channel (PUCCH) resource(s) from the base station, receives data on licensed carrier(s) and unlicensed carrier(s) which are aggregated, and after generating the feedback information, transmits the feedback information to the base station through the corresponding PUCCH resource(s). The problem that the base station in a License Assisted Access (LAA) system may not know about the feedback information transmitted by the terminal equipment may be solved, thereby increasing efficiency of feedback information transmission.
