Abstract
A method of operating a repeater comprises detecting a synchronization signal from a received communication signal, identifying a time division duplex (TDD) switching pattern based on a power change of the communication signal over time and switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern.
Claims10
A method of operating a repeater comprising:
- detecting a synchronization signal from a received communication signal;
- identifying a time division duplex (TDD) switching pattern based on a power change of the communication signal over time;
- and
- switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern,
- wherein the identifying the TDD switching pattern includes:
- identifying each of two or more TDD switching patterns which are alternately repeated;
- and
- verifying the TDD switching pattern according to whether a signal exists in a certain section outside a boundary of a section determined as a downlink communication section in the communication signal, based on the identified TDD switching pattern.

A repeater comprising:
- a sync detector configured to detect a synchronization signal from a received communication signal;
- a TDD pattern identifier configured to identify a time division duplex (TDD) switching pattern based on a power change of the communication signal over time;
- and
- a switching signal generator configured to generate a switching signal for switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern,
- wherein the TDD pattern identifier is configured to identify each of two or more TDD switching patterns which are alternately repeated, and
- wherein the repeater further comprises a TDD pattern decider configured to verify the TDD switching pattern according to whether a signal exists in a certain section outside a boundary of a section determined as a downlink communication section in the communication signal, based on the identified TDD switching pattern.
