US 9,871,612 B2 · Method for setting timing of response information transmission channel in TDD-FDD joint operation and apparatus therefor

Abstract

Provided are a method and an apparatus for setting timing of a response information transmission channel for uplink transmission of a terminal configured with cells operating in different duplex modes. Provided are also a method and an apparatus for setting timing for receiving a response signal in a terminal that performs communications through one or more cells operating in different duplex modes. The method may include setting both the PCell and the SCell to be self-carrier scheduled, receiving control information for PUSCH transmission from the PCell or the SCell, transmitting the PUSCH at the PCell or the SCell on the basis of the control information, and receiving a PHICH for the PUSCH transmitted on the basis of the PHICH timing of the PCell or SCell in accordance with the PUSCH transmission from the PCell or the SCell.

Dependent claims

A method of receiving a physical hybrid ARQ indicator channel (PHICH) in a terminal configured with a primary cell and a secondary cell, the method comprising:

establishing at least one of the primary cell and the secondary cell to be carrier scheduled, wherein the primary cell and the secondary cell are different cells configured to operate in different duplex modes;
receiving control information for PUSCH transmission from at least one of the primary cell and the secondary cell;
transmitting, in at least one of the primary cell and the secondary cell, a PUSCH based on the control information;
and
receiving a PHICH regarding the PUSCH from at least one of the primary cell and the secondary cell, transmitted based on PHICH timing of at least one of the primary cell and the secondary cell in response to the transmission of the PUSCH.

transmitting control information for PUSCH transmission in at least one of the primary cell and the secondary cell of the terminal;
receiving a PUSCH transmitted in at least one of the primary cell and the secondary cell based on the control information;
and
transmitting a PHICH regarding the PUSCH to at least one of the primary cell and the secondary cell, based on PHICH timing of at last one of the primary cell and the secondary cell in response to the PUSCH transmission.

2 more elements

A terminal, in which a primary cell and a secondary cell are configured, the terminal receiving a physical hybrid ARQ indicator channel (PHICH), and comprising:

a controller configured to be carrier scheduled for at least one of the primary cell and the secondary cell;
a receiver configured to receive control information from at least one of the primary cell and the secondary cell;
and
a transmitter configured to transmit a PUSCH from at least one of the primary cell and the secondary cell based on the control information,
wherein the primary cell and the secondary cell are different cells configured to operate in different duplex modes;
and
wherein the receiver is configured to receive a PHICH regarding the PUSCH transmitted from at least one of the primary cell and the secondary cell based on PHICH timing of at least one of the primary cell and the secondary cell in response to the PUSCH transmission.
