摘要： A method includes transmitting downlink signals to at least first and second mobile communication terminals over respective first and second traffic channels. Reception quality measures are obtained from the first and second mobile communication terminals for at least one of the traffic channels. Based on the reception quality measures, an expected downlink performance is estimated for simultaneous transmission to the first and second mobile communication terminals on a candidate shared traffic channel.

摘要： A method for communication includes defining a signal constellation including multiple constellation points in a signal space, such that each constellation point corresponds to a signal representing a respective combination of values of at least three bits, wherein three or more subsets of the bits in each of the constellation points are respectively allocated to three or more data streams. A sequence of signals is received, each signal selected from the signal constellation. The received sequence of the signals is demodulated, and one of the three or more data streams is reconstructed based on the demodulated signals.

摘要： A method includes assigning a communication channel for simultaneous transmission to at least first and second mobile communication terminals using a Time-Division Multiplexing (TDM) communication protocol. Upon determining that data is to be transmitted over the communication channel to both the first and the second mobile communication terminals, the data is transmitted at a first power level that is defined for transmission to the first mobile communication terminal as part of the simultaneous transmission. Upon determining that the data is to be transmitted over the communication channel only to the first mobile communication terminal, the data is transmitted at a second power level that is defined for transmission only to the first mobile communication terminal and is lower than the first power level.

摘要： Systems and methods are provided for transmitting and receiving an uplink state flag (USF) in a cellular network. A base station may transmit the USF to plurality of mobile stations that share the same frequency channel, and each mobile station can use the USF to determine whether that mobile station can transmit data in an upcoming uplink time period. The base station can encode the USF bits into a plurality of encoded USF symbols, where the encoded USF symbols may be selected from corner signal points in a QAM signal constellation set or from signal points adjacent to the corners of a QAM signal constellation set. The base station can interleave the encoded USF symbols and modulate the encoded USF symbols for transmission using the signal constellation set. A mobile station that can communication with the base station can include a corresponding receiver, de-interleaver, and decoder.

摘要： A communications terminal using interleaving may be awakened at certain times. The paging message determines whether the terminal will remain awake or it can return to sleep. The amount of time that the communications terminal is awakened may be reduced by determining whether it is necessary to demodulate all of the available time slots. In many cases, it may be possible, based on the environment in which terminal finds itself and the quality of the signals it receives, to obtain the necessary information without demodulating symbols from all the time slots in which symbols of the message are transmitted. As a result the period to receive the paging message may be reduced and the power consumption may likewise be reduced.

摘要： Apparatuses and methods are provided for generating a plurality of redundancy versions using various rate matching algorithms. In some embodiments, a rate matcher is provided that allocates systematic and parity bits to the redundancy versions in a manner that allows all of these bits to be transmitted in at least one redundancy version. In some embodiments, the rate matcher uses a first puncturing algorithm to generate both a first redundancy version and a third redundancy version, but allocates a different proportion of the systematic bits to these redundancy versions. In these embodiments, the second redundancy version may include only bits that were not transmitted in the first redundancy version.
