摘要： A distributed transmit diversity system based on OFDM signaling transmits a broadcast/multicast service signal from one or more first base stations and from one or more second base stations, wherein the first and second base stations transmit orthogonalized pilots. Correspondingly, a remote receiver, e.g., a mobile station, resolves the orthogonal pilots and makes independent channel estimates relative to the first and second base stations for improved diversity reception. Pilots are orthogonalized between the first and second base stations by using orthogonal space-time or space-frequency block coding. For example, in one embodiment, a first pilot tone pair is interleaved with data tones in the OFDM data blocks being transmitted from the first base stations, while an orthogonal second pilot tone pair is interleaved with data tones in the same OFDM data blocks being synchronously transmitted from the second base stations.

摘要： Outer loop power control (OLPC) for the reverse link considers frame information associated with at least two reverse link traffic channels, the transmit power of which is referenced to the transmit power of a reverse link pilot channel R-PICH. A traffic OLPC setpoint is determined based on information such as target frame error rate (FER) and actual frame errors associated with each traffic channel, and the traffic OLPC setpoint is converted to a R-PICH OLPC setpoint. The traffic OLPC setpoint may be calculated from weighted frame information generated by combining the received frame information. Alternatively, a traffic channel OLPC setpoint may be determined for each channel, and a weighted traffic OLPC setpoint calculated from the individual traffic channel OLPC setpoint. The setpoint adjustment may depend on received frame errors, where the power up step size is a multiple of the power down step size, the multiple calculated from target FERs.

摘要： A method and apparatus provide for setting the initial transmit power of secondary reverse link carriers used by mobile stations in conjunction with primary reverse link carriers. In one or more embodiments, a mobile station sets the initial transmit power of a secondary reverse link carrier relative to the transmit power of the primary reverse link carrier as a function of initialization transmit power information transmitted to the mobile station, which directly or indirectly considers reverse link loading information. Additional considerations may include differences in active sets associated with the primary and secondary reverse link carriers and/or sector switching activity of the mobile station.

摘要： Users in a wireless communication system are provisioned into QoS-based classes and rate controlled using a single, per-sector common rate control (CRC) sub-channel. In one or more embodiments, different mobile stations are configured to respond differently to the same CRC commands by provisioning them with different Traffic-to-Pilot Ratio (TPR) tables and/or with different TPR step size adjustment tables. That is, the network can define different classes or groups of mobile stations by sending class or group-specific TPR-related values to the mobile stations belonging to a specific class or group. With this method, the mobile stations in one group can achieve different reverse link data rates, or make more aggressive data rate changes, than those in another group, even though both groups receive the same rate control commands.

摘要： Noise is measured at one or more base stations in a mobile communication system during periodic silence periods. A periodic silence period is defined for at least one carrier that is independent of reverse link channel frame boundaries. The radio base stations transmits silence parameters defining the periodic silence period to mobile stations, which stop transmitting during the periodic silence periods. A time reference is provided to the mobile stations to synchronize the silence periods for all mobile stations.

摘要： A method of reverse link power control for a reverse packet data channel in a wireless communication system allows a mobile station to autonomously change its data transmission rate. The mobile station transmits packet data over a reverse packet data channel having a data rate variant transmit power level that varies based on a transmit data rate on the packet data channel. The mobile station further transmits control signals over a reverse control channel associated with the reverse packet data channel. The transmit power level of the reverse control channel is such that the transmit power level does not vary with the transmit data rate on the packet data channel. The radio base station measures the strength of the received signals on the reverse control channel, compares the measured strength to a power control set point, and generates a power control signal responsive to the comparison of the control signal to the power control set point.

摘要： A method of allocating forward link transmit power with respect to a mobile station that actively is associated with a serving sector and one or more non-serving sectors of a wireless communication network comprises receiving channel quality information at the non-serving sectors as reported by the mobile station for the serving sector, and allocating forward link transmit power for the mobile station at the non-serving sectors as a function of the reported channel quality information. Non-serving sectors may assume that the reported channel quality information establishes the lower power allocation bound for the mobile station on the assumption that each of them has less favorable radio conditions than the serving sector with respect to the mobile station. Thus, base station transceivers operating as non-serving transmitters with respect to a given mobile terminal may nonetheless determine forward link transmit power allocations for the mobile station using serving sector channel quality information.

摘要： A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

摘要： A method and apparatus to provide a deterministic power control mechanism for the transmission of mobile station power control commands based on transmitting non-power control commands for which mobile stations exhibit deterministic, observable responses at related transmit powers, e.g., at the same power. For example, a wireless network base station may adjust the target used for sending power control commands to a given mobile station by observing whether that mobile station correctly responds to rate control or retransmit control commands sent at the same transmit power. The mobile station's response (or non-response) to such non-power control commands is readily observable and can be taken as an indication of whether the power target is sufficient for current radio conditions. Although not so limited, this approach may be particularly beneficial where non-power control commands are sent along with the power commands on a sub-channel of a common power control channel.

摘要： A wireless communication network receives packet data transmissions from a mobile station, tracks the occurrence of retransmission requests sent to the mobile station responsive thereto, and modifies the radio link assignments for the mobile station based at least in part on said tracking. For example, a base station controller may be configured to manage the active set of a mobile station based on the number and/or frequency of NACK messages sent by the radio base stations in the mobile station's active set(s) responsive to packet data transmissions from the mobile station. The ACK/NACK response of a radio base station to mobile station transmissions may be used to detect link imbalance, identify poor reverse link channels, etc. The base station controller can add or change radio links based on the ACK/NACK response to improve reverse link performance, trigger voice call handoff, correct link imbalance, etc.
