Abstract: A wireless communication receiver receiving a multiplexed signal comprising two or more signal streams calculates a received signal quality for the multiplexed signal as a function of stream-specific received signal qualities, determines one or more loss parameters indicative of variations in the stream-specific received signal qualities, and generates quality feedback based on such information. In turn, a transmitter controls the selection of one or more transmission parameters of the multiplexed signal based on the quality feedback, such that its transmit link adaptations account for the losses in received signal quality at the receiver arising from the variations in the stream-specific received signal qualities. The quality feedback may include calculated loss values, or parameter/penalties that permit loss calculation, and the method applies to both code multiplexing and spatial multiplexing.

Abstract: Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

Abstract: The present invention relates to a method and arrangement to enhance the communication performance in wireless communication systems. The method of the invention provides better adjustment of reported SINR in MIMO, and PARC-MIMO based communication systems. According to the method information relating to signal-to-interference-plus-noise ratio is determined by the user equipment and reported to the base station. The base station adjust reported SINRs using a model of the SINR dependences of power and code allocation. The dependences is modeled by a function comprising a first parameter relating only to power allocation and a second parameter relating only to code allocation. The first parameter has a power allocation exponent and the second parameter has a code allocation exponent. Both the power allocation exponent and the code allocation exponent are data stream dependent.

Abstract: The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.

Abstract: The present invention relates to control signaling in wireless communication systems. In particular, the present invention relates to control signaling in MIMO based communication systems. In the method according to the invention control information is transferred from a base station to at least one user equipment, via a plurality of common pilot channels. A set of unique pilot sequences has been pre-defined, and the base station assigns specific pilot sequences from the set of pilot sequences to specific common pilot channels, forming a pilot sequence assignment pattern representing a specific control information. The user equipment, having knowledge of the relations between pilot sequence assignment patterns and control information, interprets the received pilot sequence assignment pattern as specific control information. The method is particularly well suited for broadcast type control information.
