摘要:
A preamble channel encoder, e.g., in a UHDR-DO system, uses a channel structure that can efficiently transmit more information bits, yet achieve sufficient detection and false alarm performance. The preamble channel encoder uses tail-biting convolutional coding and Cyclical Redundancy Check (CRC). The preamble channel structure can be used to encode, e.g., rate indicator bits, while a MAC identifier encoder, e.g., a Reed-Solomon encoder, is used to encode MAC identifier bits. The encoded rate indictor and MAC identifier bits can then be mapped to the appropriate tones in an OFDM encoding scheme.

A channel structure that can efficiently transmit more data control bits, e.g., required by future wireless communication systems, yet achieve sufficient detection and false alarm performance uses tail-biting convolutional coding and Cyclical Redundancy Check (CRC). In certain implementations, symbol repetition, interleaving and/or scrambling can also be included. Also, depending on the implementation, modulation schemes such as Bi-Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM) can be used in conjunction with the other coding techniques.

A mobile communication device is provided with a wireless module and a controller module. The wireless module performs wireless transceiving to and from a service network. The controller module receives, on a paging channel, a first predetermined number of symbols in a frame of a time slot via the wireless module, and determines whether to enter a standby mode according to the first predetermined number of symbols. Also, the controller module stops the receiving of subsequent symbols in the frame by deactivating the wireless module in response to entering the standby mode.

The first receiver has an adaptive controller, configured to determine the first rate and the first pattern. The first rate and the first pattern are selected from a plurality of rates and patterns available for transmission of the first power control bit information and the second power control bit information.
摘要:
A method determines whether information corresponding to one of a number of carriers indicates the one carrier is loaded or unloaded, wherein the carriers are used for transmission of a MAC flow by the access terminal over a reverse link. Responsively, the transmission resource allocation corresponding to the MAC flow for the one carrier is adjusted based on information corresponding to carrier loading for each of the carriers and on information corresponding to reverse link pilot power for each of the carriers. An access terminal includes a function that determines whether the one is loaded or unloaded. Responsively, the function adjusts transmission resource allocation for the MAC flow for the one carrier based on information of carrier loading for each of the carriers and on information of reverse link pilot power for each of the carriers.
摘要:
A method for controlling transmission of sets of data comprises receiving information relating to at least a part of a first data set. This information may comprise the at least part of the first set of data or an indication of receipt of the at least part of the first set of data. The number of times that at least a part of the first set of data has been transmitted is determined. At least one threshold for a quantity indicative of transmission conditions is updated based on the determined number of times, said at least one threshold being for determining a transmission rate for at least a part of a set of data. Determining a transmission rate for at least a part of a second set of data is also discussed.
