A transceiver is operated 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. Operation includes 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 transceiver operation is initiated in a full-duplex mode in which transmitted and received signals pass through a duplexer associated with a transceiver antenna. If the transmitter output power of the transceiver is in the high-power domain, then transceiver operation is initiated in a half-duplex mode and bypassing the duplexer.

Adaptive duplex modes in telecommunication equipment

The invention includes a method for a wireless connection of a wireless portable deviceto a selected wireless devicein a group of nearby wireless devices-, which deviceis provided with a short-range-unitfor a wireless communication with said group of nearby devices-, a substantially omnidirectional antennaconnected to said short-range-unitfor a substantially omnidirectional communication, and at least one directional communication devicefor a directional communication, which method includes the steps of: activating the directional communication device; directing the directional communication devicetowards a nearby device; connecting the portable deviceto the selected deviceusing the directional communication device; communicating with the selected devicevia said substantially omnidirectional antennaafter said connecting.

Ad-hoc connectivity system and method

A mobile station adapted to be used in a radio communications system includes a receiver apparatus adapted to receive blocks of distorted information bits at a first rate from a transmitter via a communications link, and a first detecting apparatus adapted to detect information bits from the distorted information bits. The mobile station also includes a second detecting apparatus adapted, when the quality of the received blocks of information bits is above a given level, to detect information bits from the distorted information bits using fewer computation resources than the first detecting apparatus.
