摘要： A synchronous discontinuous transmission medium access control (SDTX-MAC) method and apparatus for more efficiently using existing uplink channels by sharing these uplink channels between multiple terminals engaged in bursty data transmission. This is accomplished by assigning each mobile terminal an individual time slot and by not requiring each mobile terminal to broadcast its identity. This results in a reduction in the number of receivers on each base station and a reduction in the length of the synchronization message.

摘要： A CSI vector quantizer (VQ) system is provided for time-correlated channels. The VQ system operates a receiver forwarding quantized channel state information in the form of indices and a transmitter predicting channel state change. The VQ system is aimed at feedback channels, in which bit errors, erasures and delays can occur. The VQ system uses transmitter-side channel prediction algorithms that work with the quantized CSI information and allow the system to recover from feedback channel transmission errors, erasures and delays. Moreover, the techniques can be used to lower the required feedback rate, while keeping the system's throughput at the required level.

摘要： A multi-tiered CSI vector quantizer (VQ) is provided for time-correlated channels. The VQ operates by quantizing channel state information by reference to both the current channel state information and a prior channel state quantization. A system is also provided that uses multi-tiered CSI quantizers. Enhanced signaling between the transmitter and receivers is provided in order to facilitate the use of multi-tiered CSI quantizers.

摘要： A method for scheduling packet data transmissions in a wireless communication system is described wherein a priority function is based on a channel state indicator (CSI), the projected average throughput of the users, and a tuning parameter designed to control the throughput and fairness characteristics of the scheduling algorithm. The method also considers fairness criteria dictated by predetermined Quality of Service (QoS) requirements. The channel state indicator may be a Requested Data Rate (RDR) or Carrier-to-Interference ratio (C/I) information. The base station calculates a priority function for the multiple mobile users. Each priority function is a function of the CSI, the projected average throughput of a given mobile user, the average projected throughput over a set of users, and the tuning parameter.

摘要： A method and an apparatus of constructing hybrid Automatic Repeat reQuest (ARQ) systems using specific properties of the BCJR error correcting algorithm. Since the convergence to an actual codeword is not always guaranteed with the BCJR, the method and apparatus implements a system, in which two different types of Negative AcKnowledgement messages (NAKs) are employed. The first type is the conventional one-bit NAK and the second type specifies retransmission pattern in such a way that the additional parity bits are concentrated on the parts of the code trellis that did not converge to a valid sequence.
