Abstract:
1. A method of operating a transceiver in a cellular communications system, wherein the transceiver has a variable transmitter output power that spans a range of power levels comprising a low-power domain and a high-power domain, the method comprising: determining whether the transmitter output power of the transceiver is in the low-power domain or the high-power domain; if the transmitter output power of the transceiver is in the low-power domain, then initiating transceiver operation in a full-duplex mode in which transmitted and received signals pass through a duplexer associated with a transceiver antenna, wherein the duplexer obtains a level of isolation between transmitted and received signals; and if the transmitter output power of the transceiver is in the high-power domain, then initiating transceiver operation in a half-duplex mode and bypassing the duplexer.
