Abstract
Provided are a method of monitoring a control channel in a multiple antenna system, in which a plurality of layers are defined, and a wireless device using same. The wireless device monitors the control channel in a search layer that is selected from the plurality of layers.
Claims12
A method of monitoring a physical control channel in a multiple antenna system, the method comprising:
- determining, by a wireless device, a search layer associated with an antenna used for the physical control channel among a plurality of search layers based on a pre-defined pattern, wherein the pre-defined pattern is determined based on a number of subframes carrying the physical control channel;
- and
- monitoring, by the wireless device, the physical control channel in the search layer, wherein the physical control channel is received via an orthogonal frequency division multiplexing (OFDM) symbol carrying a shared data channel, and the physical control channel includes scheduling information for the shared data channel,
- wherein the pre-defined pattern is determined by the wireless device without using control information received from a base station.

A wireless device for monitoring a physical control channel in a multiple antenna system, the wireless device comprising:
- a radio frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the RF unit, the processor being configured to:
- determine a search layer associated with an antenna used for the physical control channel among a plurality of search layers based on a pre-defined pattern, wherein the pre-defined pattern is determined based on a number of subframes carrying the physical control channel, and
- monitor the physical control channel in the search layer, wherein the physical control channel is received via an orthogonal frequency division multiplexing (OFDM) symbol carrying a shared data channel, and the physical control channel includes scheduling information for the shared data channel,
- wherein the pre-defined pattern is determined by the processor without using control information received from a base station.
