Abstract:
A method for improving signal to noise ratio in an uplink transmission. The method includes determining a plurality of combinations of “N” possible users to be selected among “X” users that are transmitting signals to a base station comprising “n” number of antennas, where n>=N, wherein selected “N” users transmit on a same sub-carrier; computing signal to noise ratio (SNR) of the signals received from each of the users among the determined combination of “N” possible users; and selecting at least one combination among the plurality of combinations of “N” possible users, such that, a combined signal to noise ratio of the selected combination is maximum among all combinations.

Claim (Index 20):
A method for accommodating multiple users transmitting on a same sub-carrier to a base station comprising n antennas, the method comprising:\n enabling a first user to transmit two bits through two antennas of a user equipment of the first user; decomposing a (n\u00d72) channel matrix of the first user using Singular Value Decomposition (SVD), into three matrices, wherein the matrices are a (n\u00d7n) unitary matrix which is denoted by \u201cU\u201d, a (n\u00d72) partial diagonal matrix which is denoted by \u201cS\u201d and a precoder (2\u00d72) unitary matrix which is denoted by \u201cV H \u201d; enabling other (n\u22122) users in the base station to transmit one data bit each through two antennas to the base station on same sub-carrier as the first user; computing effective channel matrix of the first user; computing effective channel vectors of the (n\u22122) users using \u201cU\u201d; computing transmit precoders of the (n\u22122) users using \u201cU\u201d; and computing signal to noise ratio and decoding the input bits of the users by applying Interference Rejection Combining (IRC) function using the signals received by the n antennas of the base station and effective channel vectors of the first user and the (n\u22122) users.
