Abstract: A communication system that provides fast and reliable communications. The system is suitable for use in connection with wireless computing devices in which transmission errors may occur because of channel conditions, such as interference. Channel conditions causing transmission errors may be bursty and transient such that the errors temporarily overwhelm an error control code. By combining data received for multiple transmission attempts of a packet that fail error checking or that pass error checking with low reliability, a reliable representation of the packet may be quickly constructed. Though, combining may be omitted when a transmission attempt is received that passes error checking with high reliability.

Abstract: Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors based on the same transmitted vector. The symbols of the received signal vectors are combined, forming a combined received signal vector that may be treated as a single received signal vector. The combined received signal vector may be equalized by, for example, a zero-forcing or minimum-mean-squared error equalizer or another suitable linear equalizer. Following equalization, the equalized signal vector may be decoded using a simple, linear decoder.

Abstract: Example embodiments include methods of interference cancellation at NodeB receivers of baseband antenna signals including physical channels. The methods include canceling interference from a received baseband antenna signal by removing a reconstructed baseband signal from the processed received baseband antenna signal. The processed reconstructed baseband signal includes users whose physical data channel signals were successfully decoded. Methods also include removing interference from a received baseband signal to form an interference cancelled baseband signal that will be processed by the receiver. The interference cancelled baseband signal is the received baseband antenna signal minus users' signal interference contributions whose demodulated physical data channel signals have a determined user symbol energy value that exceeds a threshold. Methods further include removing interference from a user's signal to be error corrected. The interference is symbol interference from an earlier successfully decoded user's symbols. The user symbol interference is determined by cross correlations.

Abstract: At least one timer is used to prevent a stall condition. If a timer is not active, the timer is started for a data block that is correctly received. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. When the timer is stopped or expires, all correctly received data blocks among data blocks up to and including a data block having a sequence number that is immediately before the sequence number of the data block for which the timer was started is delivered to a higher layer. Further, all correctly received data blocks up to a first missing data block, including the data block for which the timer was started, is delivered to the higher layer.
