Claim:
1. A method for determining a switching point from downlink (DL) to uplink (UL) in a Time Division Duplexing (TDD) wireless communication system, the method comprising: controlling, by a processing device, detecting a cyclic prefix (CP) type based only on detection of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) of a base station; controlling, by the processing device, determining a channel bandwidth used in the base station based on the CP type; controlling, by the processing device, sampling a channel of the base station at a sampling rate corresponding to the channel bandwidth to obtain samples; controlling, by the processing device, determining, from the samples, (i) each DL antenna port of the base station being used by the base station, (ii) TDD configuration of the base station, and (iii) Special Subframes (SSF) configuration of the base station; and controlling, by the processing device, determining of the switching point based on the channel bandwidth, each DL antenna port of the base station determined as being used by the base station, the TDD configuration of the base station and the SSF configuration of the base station.
