Abstract: A method of communicating provides multi-radio transmission diversity (MRTD). A base station receives downlink measurement reports from a mobile station regarding each of a plurality of downlinks between the mobile station and a plurality of base stations. The base station determines which of the base stations will transmit a selected transmission to the mobile station responsive to the received downlink measurement reports. The base station later receives an acknowledgement from the mobile station receiving the selected transmission. In a disclosed example, each of a plurality of base stations receives the downlink measurement reports. Each of the base stations determines, independent of the other base stations, which of the base stations will transmit the selected transmission.

Abstract: A transmit power control technique within a wireless communication system includes adjusting a transmit power used by a picocell base station unit based upon a position of the picocell within a macrocell. When a picocell base station unit is located relatively close to a macrocell base station or center of the macrocell, the transmit power of the picocell base station unit is increased to avoid downlink interference from the macrocell base station for mobile stations communicating within the picocell. When a picocell base station unit is located relatively close to an edge of a macrocell, the transmit power of the picocell base station is decreased to avoid interference caused by the picocell base station unit for mobile stations communicating within the macrocell in the vicinity of the picocell.

Disclosed examples include utilizing information from a plurality of mobile stations.

Abstract: The present invention provides a method and an apparatus for communicating data over a network between a communication node, for example, an access point having a first and a second antenna and a first and a second mobile station. The method comprises weighting a first data at the access point to transmit the first data using the first and second antennas so that the first mobile station only receives the first data and weighting a second data at the access point to transmit the second data using the first and second antennas so that the second mobile station only receives the second data. A space division multiple access (SDMA) module may cause a transmission protocol to transmit the first data to the first mobile station on the downlink and transmit the second data to the second mobile station in parallel to the transmission of the first data on the downlink.

Abstract: A method of decoding is provided comprising processing iterations. In each processing iteration, there is a first Max-Log-MAP decoding operation giving rise to a systematic error due to the Max-Log approximation, and a first weighting operation to weight extrinsic information from the first decoding operation to be applied as a priori information to the second Max-Log-MAP decoding operation. This is followed by a second Max-Log-MAP decoding operation, also giving rise to a systematic error due to the Max-Log approximation, and a second weighting operation to weight extrinsic information from the second decoding to be applied as a priori information to the first Max-Log-MAP decoding of the next iteration. The weights are applied to compensate for the systematic error due to the Max-Log approximation made in the last Max-Log-MAP decoding operation.
