摘要： This document discloses methods, apparatuses, and computer programs for selecting and providing a terminal apparatus of a wireless network with services. The terminal apparatus selects a wireless apparatus to provide the terminal apparatus with at least a first service. Then, it causes transmission of an association request to the wireless apparatus, wherein the association request comprises at least one information element indicating whether the request relates to provision of the first service without a second service or to provision of both the first service and a second service, wherein the second service is different from the first service and is subjected to the presence of the first service. Upon approval acquired from the wireless apparatus, the at least said first service is received from the wireless apparatus.

摘要： A multi-level space time signal constellation that is optimized for use with a multi-carrier, multi-path communication scheme includes points on a first level separated from points on a mutually exclusive second level by a minimum distance that is based on a conditional probability distribution, preferably a Kullback-Leibler (KL) distance. Points within one level may be separated by a Euclidean distance, but spherical levels are rotated relative to one another to maximize a minimum inter-level KL distance. A receiver uses pilot symbols to estimate the channels and two-stage symbol detection, determining in one stage the constellation level and in another stage the point in the level. The receiver calculates a likelihood function based on a conditional distribution which does not reduce to the Euclidean-based nearest-neighbor detector. A single stored constellation may be scaled based on received signal to noise ratio. Each constellation defines n=2M real dimensions, wherein M is the number of transmit antennas.
