Abstract: A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

Abstract: A method for transmitting feedback information for a wireless transmit receive unit (WTRU) includes multiplexing the feedback information with an uplink shared channel, mapping the multiplexed feedback information to OFDM symbols and transmitting the feedback information to an evolved Node B (eNB). The method also includes multiplexing the feedback information with the uplink shared channel using distributed frequency division multiplexing (FDM), mapping the feedback information to a first orthogonal frequency division multiplex (OFDM) symbol, and distributing the mapped feedback information equidistantly across the transmission bandwidth.

Abstract: A METHOD AND APPARATUS FOR IMPLEMENTING SPATIAL PROCESSING WITH UNEQUAL MODULATION AND CODING SCHEMES (MCSS) OR STREAM-DEPENDENT MCSS ARE DISCLOSED. INPUT DATA MAY BE PARSED INTO A PLURALITY OF DATA STREAMS, AND SPATIAL PROCESSING IS PERFORMED ON THE DATA STREAM (203A - 203NRX) TO GENERATE A PLURALITY OF SPATIAL STREAM (107A -107NSS). AN MCS FOR EACH DATA STREAM IS SELECTED INDEPENDENTLY. THE SPATIAL STREAMS (107A - 107NSS) ARE TRANSMITTED VIA MULTIPLE TRANSMIT ANTENNAS. AT LEAST ONE OF THE TECHNIQUES OF SPACE TIME BLOCK CODING (STBC), SPACE FREQUENCY BLOCK CODING (SFBC), QUASI- ORTHOGONAL ALAMOUTI CODING, TIME REVERSED SPACE TIME BLOCK CODING, LINEAR SPATIAL PROCESSING AND CYCLIC DELAY DIVERSITY (CDD) MAY BE PERFORMED ON THE DATA/SPATIAL STREAMS (107A - 107NSS). AN ANTENNA (126A - 126NTX) MAPPING MATRIX MAY THEN BE APPLIED TO THE SPATIAL STREAMS (170A -107NSS). THE SPATIAL STREAMS (107A - 107NSS) ARE TRANSMITTED VIA MULTIPLE TRANSMIT ANTENNAS. THE MCS FOR EACH DATA STREAM MAY BE DETERMINED BASED ON A SIGNAL-TO-NOISE RATIO OF EACH SPATIAL STREAM ASSOCIATED WITH THE DATA STREAM.

Abstract: A receiver and receiving method for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI) are disclosed. A receiver includes a plurality of H-ARQ processes to receive multiple transport blocks (TBs) simultaneously per TTI. After receiving a plurality of TBs, which were assigned to multiple H-ARQ processes and after receiving the corresponding control information, the receiver sends feedback to each of the TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter.

Abstract: A method and apparatus for implementing spatial processing with unequal modulation and coding schemes (MCSs) or stream-dependent MCSs are disclosed. Input data may be parsed into a plurality of data streams, and spatial processing is performed on the data streams to generate a plurality of spatial streams. An MCS for each data stream is selected independently. The spatial streams are transmitted via multiple transmit antennas. At least one of the techniques of space time block coding (STBC), space frequency block coding (SFBC), quasi-orthogonal Alamouti coding, time reversed space time block coding, linear spatial processing and cyclic delay diversity (CDD) may be performed on the data/spatial streams. An antennal mapping matrix may then be applied to the spatial streams. The spatial streams are transmitted via multiple transmit antennas. The MCS for each data stream may be determined based on a signal-to-noise ratio of each spatial stream associated with the data stream.

Abstract: Se divulga un método y un aparato de comunicaciones inalámbricas para codificar y decodificar los vectores de formacion de haz. Una estacion base envía senalizacion explícita para un vector de formacion de haz de una unidad de transmision/recepcion inalámbrica (WTRU) y senalizacion implícita para vectores de formacion de haz de WTRUs que interfieren. Cada WTRU utiliza su propio vector de formacion de haz para estimar los vectores de formacion de haz de cada una de las otras WTRUs.
