US 2014/0211768 A1 · ACK/NACK FEEDBACK METHOD IN WIRELESS COMMUNICATION SYSTEM

Abstract

A method of ACK/NACK feedback in a wireless communication system. The method includes determining, by a UE, a number of public sub-frames, all of which are uplink sub-frame in PCC and any SCC sub-frames of any radio frame in frame structure configurations according to the frame structure configurations of the PCC and any SCC, selecting, by the UE, a configuration, uplink sub-frames of which merely include sub-frames corresponding to the determined number of public sub-frames from existing seven kinds of frame structure configurations, and feeding back, by the UE, to an eNB ACK/NACK information corresponding to PDSCH in the SCC on the PCC adopting a timing relationship between the PDSCH and the ACK/NACK corresponding to the selected configuration.

An Acknowledgement/Non Acknowledgement (NACK) feedback method in a wireless communication system, the method comprising:

determining, by a User Equipment (UE), a number of public sub-frames, all of which are uplink sub-frame in Primary Component Carrier (PCC) and any Secondary Component Carrier (SCC) sub-frames of any radio frame in frame structure configurations according to the frame structure configurations of the PCC and any SCC;
selecting, by the UE, a configuration, uplink sub-frames of which merely comprise sub-frames corresponding to the determined number of public sub-frames from existing seven kinds of frame structure configurations;
and
feeding back, by the UE, to an Evolved NodeB, (eNB) ACK/NACK information corresponding to Physical Downlink Shared Channel, (PDSCH) in the SCC on the PCC adopting a timing relationship between the PDSCH and the ACK/NACK corresponding to the selected configuration.

An Acknowledgement (ACK)/Non Acknowledgement (NACK) feedback method in a wireless communication system, the method comprising:

notifying, by an Evolved NodeB (eNB), a User Equipment (UE) of configured information of a Primary Component Carrier (PCC), and all Secondary Component Carriers (SCC) through high-level signaling, wherein the configured information of the PCC and all SCCs of the UE comprises:
a frame structure configuration of each Component Carrier (CC) configured for the UE, and further comprises:
a number of the PCC and all SCCs;
determining, by the UE, a frame structure configuration according to the information of the frame structure configurations of the PCC and all SCCs sent from the eNB;
and
feeding back, by the UE, to the eNB, ACK/NACK information corresponding to Physical Downlink Shared Channel (PDSCH) in the SCCs on the PCC adopting a timing relationship between the PDSCH and the ACK/NACK corresponding to the determined frame structure configuration.
