摘要： Method and apparatus for a channel sensitive scheduler for scheduling transmissions in a communication system. The scheduler is defined by a priority function of the channel condition as determined by amount of transmission power needed by a mobile station. In one embodiment the channel condition is determined based on the transmission pilot power of each mobile station and is used to calculate a priority value for each mobile station. The mobile stations are then scheduled to transmit based on the priority value.

摘要： Systems and methods for selecting data rates at which to transmit data over a primary uplink in the presence of one or more secondary uplink channels. One embodiment comprises a method including determining probabilities associated with numbers of attempted transmissions of data, determining the number of times pending data transmissions have been attempted, determining probabilities associated with the data transmissions, and allocating power for transmission of the data in a succeeding frame based upon the associated probabilities. In one embodiment, a highest supportable data rate for a primary uplink is initially selected. Then, power is allocated for a minimum set of channels on the primary uplink. Then, power is allocated for pending data transmissions on the secondary uplink. A maximum power level for the transceiver is then adjusted to account for the allocated power, and the highest supportable data rate for the primary uplink is recomputed.

摘要： Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.
