Abstract:
1. A method comprising providing a number of data streams at a user equipment, wherein the number of data streams is smaller than a number of transmit antennas of the user equipment and wherein the data streams of the user equipment are transmitted as an effective radio channel simultaneously over a same communication bandwidth with at least one other data stream transmitted by another user equipment, applying a spatial pre-coding to the data streams operable for beam forming a signal carrying the data streams for steering the effective radio channel between the user equipment and the base station to increase achievable data throughput for the communication bandwidth, wherein the achievable data throughput includes the data streams transmitted by the user equipment and said at least one other data stream transmitted simultaneously over the communication bandwidth by said another user equipment, and transmitting the spatially pre-coded data streams to the base station via the transmit antennas.
