摘要： A base station transmitter for a broadcast/multicast single frequency network may include a base station component configured to randomize a phase of the signal for the base station transmitter to transmit, wherein the base station transmitter is configured to transmit a signal having a frequency common to a frequency of a signal sent by another base station component in the network. A method for improving performance of single frequency networks may include transmitting single frequency signals from base stations with pseudo-random phases including in the signals, data that permits a receiver compatible with the network to synchronously replicate the pseudo-random phases used in the transmission of the single frequency signals.

摘要： Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality.

摘要： The present invention provides a method for allocating portions of a frame to a plurality of mobile units including a plurality of frequency subcarrier sets and a plurality of symbols. The method includes determining at least one zone comprising at least one of the plurality of subcarrier sets and at least one of the plurality of symbols and determining a plurality of subzones. Each subzone includes at least one of the plurality of subcarrier sets and at least one of the plurality of symbols in the at least one zone. The method also includes associating each of the plurality of mobile units with at least one of the subzones and allocating a portion of the subcarrier sets and symbols in each subzone to the mobile units associated with each subzone.

摘要： In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

摘要： A wireless endpoint employs frequency hopping for communicating signals in a wireless communications system. Over a time period T, the wireless endpoint performs pseudo-random selection of a frequency from a hopping set of N frequencies such that over at least a portion of the time period T, the frequency selection is constrained to less than the N frequencies.
