US 10,383,113 B2 · Method and apparatus for performing blind detection in wireless communication system

Abstract

A method and apparatus for determining a length of a physical downlink shared channel (PDSCH) (or, a partial subframe) in a wireless communication system is provided. A user equipment (UE) detects at least one of starting orthogonal frequency division multiplexing (OFDM) symbol or ending OFDM symbol of a PDSCH in an unlicensed carrier, and determines the length of the PDSCH in the unlicensed carrier based on the at least one of the starting OFDM symbol or the ending OFDM symbol of the PDSCH in the unlicensed carrier. The UE may detect the at least one of starting OFDM symbol or ending OFDM symbol based on a physical downlink control channel (PDCCH) or a reference signal (RS) pattern.

Dependent claims

A method for receiving, by a user equipment (UE), a downlink signal in an unlicensed carrier in a wireless communication system, the method comprising:

receiving subframe information for the unlicensed carrier via downlink control information (DCI) from a network;
determining that a first subframe is a partial subframe according to the subframe information for the unlicensed carrier, wherein the partial subframe occupies only a part of orthogonal frequency division multiplexing (OFDM) symbols in the first subframe;
determining that a second subframe, which immediately follows the first subframe, is a full subframe, which occupies all of OFDM symbols in the second subframe;
and
receiving the downlink signal from the network in the unlicensed carrier via the first subframe and the second subframe.
