Abstract: A remote station, for a wireless communication system, includes a receiver configured to receive on a first downlink a synchronization control channel on a first carrier frequency and on a second downlink a shared physical channel on a second carrier frequency different than the first carrier frequency. The shared physical channel includes a first physical shared channel having a unicast signal and a second physical shared channel having a multicast or broadcast signal, the unicast signal being multiplexed in time with the multicast or broadcast signal. The remote station includes a control processor configured to generate an acknowledgement signal on an uplink based on the unicast signal.

Abstract: 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.

Abstract: 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.

Abstract: Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for processing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.

Abstract: System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.

Abstract: Power control of mixed voice and data transmissions is disclosed. A voice signal is transmitted at a dynamically-adjusted voice transmit power capped at a maximum voice transmit power limit. Concurrently, data bursts are transmitted on top of the voice signal. Data noise is inserted between the data bursts transmissions. The data burst and inserted data noise are transmitted at a dynamically-adjusted data transmit power based on the voice transmit power to restrict the rate of change of the data transmit power until a maximum data transmit power limit is reached.

Abstract: In accordance with a method for increasing the capacity of a channel in a communications system, characteristics of a channel may be evaluated. The channel may include a plurality of slots, and the slots may have a slot format among a set of slot formats. A slot format among the set of slot formats may be selected. The selection may be based on the evaluated characteristics of the channel. Selecting the slot format may include selecting the position of a signal within each of the plurality of slots. The position of the signal may be different for each of the slot formats. The signal may be transmitted in each of the plurality of slots over the channel.

Abstract: 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.

Abstract: Schemes to time-align transmissions from multiple base stations to a terminal. To achieve time-alignment, differences between the arrival times of transmissions from the base stations, as observed at the terminal, are determined and provided to the system and used to adjust the timing at the base stations such that terminal-specific radio frames arrive at the terminal within a particular time window. In one scheme, a time difference between two base stations is partitioned into a frame-level time difference and a chip-level time difference. Whenever requested to perform and report time difference measurements, the terminal measures the chip-level timing for each candidate base station relative to a reference base station. Additionally, the terminal also measures the frame-level timing and includes this information in the time difference measurement only if required. Otherwise, the terminal sets the frame-level part to a predetermined value (e.g., zero).
