US 10,219,275 B2 · Method and apparatus for uplink transmission

Abstract

Disclosed are a method and an apparatus for uplink transmission. A method for uplink transmission for a machine-type communication (MTC) terminal comprises: a step of transmitting first uplink (UL) information via a first UL channel in a first terminal-specific frequency band of a first subframe; and a step of transmitting second UL information via a second UL channel in a second terminal-specific frequency band of a second subframe subsequent to the first subframe. The first subframe and the second subframe each include a plurality of orthogonal frequency division multiplexing (OFDM) symbols. If the first terminal-specific frequency band and the second terminal-specific frequency band do not overlap one another, the second UL information may not be transmitted in a first OFDM symbol of the second subframe. Thus, a wireless resource can be efficiently utilized.

Dependent claims

A method for an UL (uplink) transmission of a terminal, the method comprising:

determining whether a PUSCH (Physical Uplink Shared Channel) is to be transmitted on a second subframe in a second band,
wherein the second subframe is contiguous to a first subframe,
wherein the first subframe is a subframe on which a PUCCH (Physical Uplink Control Channel) is transmitted,
wherein the second band is different from a first band of the first subframe on which the PUCCH is to be transmitted,
wherein a part of the second subframe of the second band is used as a guard period, and
wherein the guard period is used for retuning frequency between a transmission of the PUCCH on the first subframe and a transmission of the PUSCH on the second subframe;
and
transmitting the PUSCH on the second subframe in the second band,
wherein the PUSCH is not transmitted in the guard period of the second subframe.
