Title:
METHODS AND APPARATUS FOR UPLINK CHANNEL ACCESS AND TRANSMISSIONS FOR LTE ON UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2016/108584
Kind Code:
A1
Abstract:
Methods and apparatuses for efficient data transmission in a wireless communication system. A method includes receiving a predefined downlink-uplink (DL-UL) subframe configuration from an eNodeB (eNB), wherein the eNB cooperates with at least one neighbor eNB that belongs to an asynchronous licensed assisted access (LAA) cell operating on at least one LAA carrier. The method further includes performing a listen before talk (LBT) procedure before transmitting UL data in the at least one LAA carrier and transmitting the UL data in accordance with the LBT procedure based on the DL-UL subframe configuration.
