Claim:
1. A method of controlling uplink/downlink (UL/DL) switching for half-duplex operation of user equipment (UE) in which UL and DL transmissions occur on different frequencies, the method comprising: determining a duration of time required for the UE to switch between UL operation and DL operation; determining a time interval required by the UE to perform a measurement operation; determining a minimum number of subframes required for the measurement operation in the time interval; controlling a switching configuration of the UE based on the determined duration of time, the determined time interval, and the minimum number of subframes; and controlling the switching configuration such that the UE conforms to at least one pre-defined condition among the following: at most a first number of DL physical signals are lost or do not occur during the time interval; at most a second number of DL common physical channels are lost or do not occur during the time interval; at most a third number of DL dedicated physical channels are lost or do not occur during the time interval; at most a fourth number of UL physical signals are lost or do not occur during the time interval; at most a fifth number of UL common physical channels are lost or do not occur during the time interval; and at most a sixth number of UL dedicated physical channels are lost or do not occur during the time interval.
