US 10,542,548 B2 · Method for receiving device-to-device signal in wireless communication system supporting carrier aggregation, and apparatus therefor

Abstract

The present invention relates to a method for receiving a device-to-device signal of a terminal in a wireless communication system supporting frequency division duplex (FDD) band and time division duplex (TDD) band-based carrier aggregation. Particularly, the present invention comprises a step for receiving a D2D signal on an uplink cell of the FDD band according to whether a wide area network (WAN) signal of the TDD band is transmitted and received on a specific sub-frame in which the WAN signal is received on a downlink cell of the FDD band, wherein the D2D signal is received when the TDD band transmits the WAN signal and a reception circuit (RX chain) for the TDD band is reconfigured for the uplink cell of the FDD band.

Dependent claims

A method of receiving a device-to-device (D2D) signal, by a user equipment (UE) in a wireless communication system, the method comprising:

configuring a frequency division duplex (FDD) band and a time division duplex (TDD) band, wherein each of the FDD band and the TDD band is related to a respective reception circuit, and
receiving the D2D signal on and uplink component carrier (CC) of the FDD band based on whether a wide area network (WAN) signal of the TDD band is transmitted or received on a specific subframe in which a WAN signal is received on a downlink CC of the FDD band,
wherein when the WAN signal of the TDD band is transmitted on the specific subframe, the D2D signal is received on the uplink CC of the FDD band using the reception circuit related to the TDD band.

Dependencies are inferred from the claim text.
