  • Publication number: 20220337705
    Abstract: The invention discloses a method for a cellular communications system, in which traffic is sent in frames, each frame comprising a first number of subframes, with a second number of said subframes being available for at least either uplink or downlink traffic. At least one of said second number of subframes is made to comprise at least three parts, as follows: One part which is utilized for uplink traffic, One part which is utilized for downlink traffic, One part which is utilized as a guard period, with said guard period part being scheduled between the uplink and the downlink parts. The duration of at least two of said three parts may be varied to fit the current system need.

  • Patent number: 6760361
    Abstract: A special coding scheme is disclosed for more effectively acquiring a long code and frame timing during a cell search in a CDMA communications system. A code set of length M Q-ary code words including symbols from a set of Q short codes is defined with certain properties. The primary property to be satisfied is that no cyclic shift of a code word yields a valid code word. The other properties to be satisfied are that there is a one-to-one mapping between a long code message and a valid code word, and a decoder should be able to find both the random shift (thereby implicitly finding the frame timing) and the transmitted code word (i.e., its associated long code indication message) in the presence of interference and noise, with some degree of accuracy and reasonable complexity.

  • Patent number: 6728319
    Abstract: A decoder in a communication system using channel optimized vector quantization and including an encoder stores active encoder centroids ci corresponding to active indices i, an active index being defined as an index that has a predetermined source probability pi>0 of being selected by the encoder for transmission to the decoder, source probabilities pi and the bit error rate epsilon to dynamically estimate a decoded vector using a sub-optimal algorithm in which only the most significant contributions are considered.

  • Patent number: 6189123
    Abstract: Apparatus, and an associated method, facilitates the efficient utilization of a channel extending between a sending and a receiving station of a digital communication system. A block of symbols to be transmitted by the sending to the receiving station is encoded utilizing a parallel-concatenated encoding technique. Selected encoded versions, or portions thereof, are transmitted by the sending station to the receiving station. The receiving station decodes the signals received thereat. If recovery of the informational content of the block of symbols cannot be effectuated, a request is made to transmit additional encoded versions, or portions thereof, of the block of symbols.
