US 2016/0081107 A1 · COMMUNICATION METHOD CONSIDERING CARRIER TYPE AND APPARATUS FOR SAME

Abstract

The present invention relates to a method for a terminal, which operates in a half-duplex manner, to communicate with a base station in a wireless communication system supporting a plurality of carrier types, and an apparatus for the same. More particularly, the present invention relates to a method and an apparatus for the same, the method comprising the step of: transmitting a signal to, or receiving a signal from, a base station in a first cell set to be in a time division duplex (TDD) manner via a first subframe positioned between a downlink subframe and an uplink subframe, wherein if the first cell operates as a first carrier type, the first subframe includes a first downlink section, a first protection section, and a first uplink section, and if the first cell operates as a second carrier type, the first subframe includes only a second downlink section and a second protection section, or includes only a second uplink section and the second protection section. The first carrier type represents a carrier type in which a cell-common reference signal is transmitted over the entire system band in all subframes, and the second carrier type represents a carrier type in which the cell-common reference signal is transmitted over at least a part of the system band in some subframes.

Dependent claims

A method for communicating with a base station by a user equipment (UE) operating in half-duplex in a wireless communication system for supporting a plurality of carrier types, the method comprising:

transmitting or receiving a signal to or from the base station through a first subframe located between a downlink subframe and an uplink subframe in a first cell configured in time division duplex (TDD),
wherein when the first cell operates as a first carrier type, the first subframe comprises a first downlink period, a first guard period, and a first uplink period,
wherein when the first cell operates as a second carrier type, the first subframe comprises only a second downlink period and a second guard period or comprises only a second uplink period or the second guard period, and
wherein the first carrier type indicates a carrier type in which a cell-common reference signal is transmitted over an entire system band in all subframes, and the second carrier type indicates a carrier type in which the cell-common reference signal is transmitted over at least part of the system band in some subframes.

1 more element

A user equipment (UE) operating in a wireless communication system for supporting a plurality of carrier types, the UE comprising:

a radio frequency (RF) unit;
and
a processor, wherein the processor is configured to:
transmit or receive a signal to or from the base station through a first subframe located between a downlink subframe and an uplink subframe in a first cell configured in time division duplex (TDD) through the RF unit,
wherein when the first cell operates as a first carrier type, the first subframe comprises a first downlink period, a first guard period, and a first uplink period,
wherein when the first cell operates as a second carrier type, the first subframe comprises only a second downlink period and a second guard period or comprises only a second uplink period or the second guard period, and
wherein the first carrier type indicates a carrier type in which a cell-common reference signal is transmitted over an entire system band in all subframes, and the second carrier type indicates a carrier type in which the cell-common reference signal is transmitted over at least part of the system band in some subframes.
