摘要： Certain aspects of the present disclosure provide a method for performing interference suppression in spatial division multiple access (SDMA) systems. When the number of receive antennas of a receiver is equal or larger than the number of spatial streams intended for the receiver, the receiver may perform interference suppression on the signals received on all of its antennas. In addition, certain aspects of the present disclosure present a flexible SDMA technique in which a plurality of channel estimates that may be received from an explicit feedback or estimated implicitly, are combined. The combined channel estimate may be used in calculating the SDMA weights.

摘要： Techniques for transmitting and receiving data in a communication system are described. A receiver may iteratively decode a data packet and may obtain better performance with more decoding iterations. The receiver may select the number of decoding iterations based on at least one parameter (e.g., packet size) to tradeoff between decoder throughput and link performance. In one design, a transmitter may obtain a transport format selected based on the number of decoding iterations, process a data packet in accordance with the transport format, and send a transmission of the data packet to the receiver. The receiver may receive the transmission of the data packet and may perform decoding for the data packet for up to the selected number of decoding iterations. The transport format and/or CQI information may be determined based on an expected degradation in link performance due to the receiver performing the selected number of decoding iterations.

摘要： Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.

摘要： An apparatus and method for enhanced downlink processing of received channels in a mobile communications system is described, containing a buffer for control data and traffic data, a demapper engine with at least two independently operating demappers for demapping the control and traffic data, a log-likelihood-ratio (LLR) buffer for supporting memory segments accessible by the demapper engine, a decoder engine containing decoders, each of the decoders operating on data from selected memory segment(s) of the LLR buffer, and an arbitrator providing control of at least one of the demapper engine, LLR buffer, and decoder engine. At least one of the decoders is suited for decoding control data and another one of the decoders is suited for decoding traffic data. By partitioning the decoding as such, an increase in downlink throughput can be obtained.
