摘要： A Hybrid Automatic Retransmission Request (H-ARQ) technique is provided for Multi-Input Multi-Output (MIMO) systems. The technique changes the basis (V) upon retransmission, which helps reduce the error probability upon retransmission. This basis hopping technique provides for improved performance gain without significant increase in design complexity. In one embodiment, communication device (100) includes a receiver section (114) for receiving an acknowledgment (ACK) or a non-acknowledgment (NACK) signal in response to information transmitted by the transmitter section of the communication device. If a NACK is received, a new basis is selected from a set of basis stored in a basis set unit (110). The new basis that is selected is then used by a linear transformation unit (106) in the retransmission of the information.

摘要： Method for exploiting frequency diversity in a multi-carrier communications system to improve retransmission performance. A preferred embodiment comprises receiving the request for retransmission, formatting data for the retransmission, selecting a carrier from a plurality of carriers, and transmitting the retransmission on the selected carrier. The selected carrier may be different from a carrier used transmit the damaged transmission, thereby frequency diversity is exploited to change the probability of successful transmission in the retransmission. Alternatively, the retransmission may take place at a later time, to permit changes in the selected carrier to take place and obtain frequency diversity via the changed carrier.

摘要： A method for providing interference suppression in a communication device includes receiving a signal, determining if the received signal comprises a Gaussian Minimum Shift Keying (GMSK) or an 8 phase shift keying (8PSK) signal. Over sampling and inphase and quadrature phase separation with real-valued signal processing on the received signal is performed whenever the received signal is determined to be a GMSK signal. Oversampling with complex-valued signal processing on the received signal is performed whenever the received signal is determined to be an 8PSK signal.

摘要： Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

摘要： A method for reducing multiple access interference (MAI) in a code division multiple access (CDMA) spread spectrum receiver assigned a number of codes which also despreads the received signal with the remaining codes of the same spreading factor. For forward link transmission with orthogonal codes, as in 3GPP and 3GPP2, interferers using larger spreading factors than the one used by the referenced mobile will have codes that are formed from the orthogonal codes of the same spreading factor as the multicodes corresponding to the referenced mobile. As a consequence, in a multipath environment, the output of a despreader using any of these remaining orthogonal codes will provide an estimate of the composite interference attributed to signals, if any, using codes that partly comprise the corresponding orthogonal code. No decisions are made for the previous despreader's output because it corresponds to a sum of interferers with unknown powers. However, this soft output can be re-spread and subtracted from the received signal prior to despreading, thereby removing the corresponding composite interference. This can significantly improve the performance of a receiver performing interference cancellation of both assigned and interfering signals, especially when the interfering signals have a substantial total power.
