摘要： A wireless communication network improves reverse link communication performance by changing one or more Automatic Repeat Request (ARQ) control settings as a function of measured or estimated reverse link loading. Control settings can be changed on a per-sector basis, allowing consideration of different loading conditions in different radio sectors of the network. Further, control settings can be changed for individual mobile stations, or selected groups of mobile stations, allowing different ARQ controls to be used for different mobile stations. By way of non-limiting example, a control circuit in a base station controller can be configured to take advantage of light reverse link loading conditions in a given radio sector by changing the ARQ control parameter(s) used for one or more mobile stations operating in that sector so that fewer ARQ retransmissions are required for those mobile stations to transmit reverse link data to the network.

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： A base station generates per-cell ACK/NACK responses rather than per-sector ACK/NACK responses. For a given mobile station signal received in softer handoff at two of the base station's sectors, the base station generates an ACK response if at least one of the soft handoff sectors correctly receives the signal, and otherwise generates a NACK response. Alternatively, the base station can combine the softer handoff signals and generate ACK/NACK responses based on whether the combined signal is correctly received. Since only one set of ACK/NACK responses are generated for all of the softer handoff sectors, the base station can use the forward link in just one softer handoff sector to send the ACK/NACK responses to the mobile station, consuming fewer forward link transmit resources at the base station. Or, the base station can send the same ACK/NACK responses from two or more softer handoff sectors, thus allowing diversity combining of the ACK/NACK responses at the mobile station.

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 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.

摘要： A communication transceiver transmits a power-controlled first signal responsive to received power control commands and transmits one or more additional signals at variable power gains relative to the transmit power of the first signal based on reception quality feedback received for the additional signals. Thus, a mobile station may transmit a traffic channel at a variable power gain relative to its pilot signal power and vary that gain responsive to reception quality feedback received by it for the traffic signal. Of course, the mobile station may float more than one traffic channel using variable gains and may use different variable gains for each one. Further, the mobile station may float one or more non-pilot channels relative to the pilot or relative to another channel, while transmitting one or more fixed gain channels. Similar variable power gain may be employed at network base stations for forward link signals.

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 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.
摘要翻译：一种提供确定性功率控制机制的方法和装置，用于基于传输非功率控制命令来发送移动台功率控制命令，所述非功率控制命令用于以相同的功率在相关的发射功率下显示出确定性的，可观测的响应。例如，无线网络基站可以通过观察该移动台是否正确地响应速率控制或以相同发射功率发送的重发控制命令来调整用于向给定移动台发送功率控制命令的目标。移动台对这种非功率控制命令的响应（或不响应）是容易观察到的，并且可以被视为当前无线电条件下功率目标是否足够的指示。尽管没有这样的限制，但是当非功率控制命令与公共功率控制信道的子信道上的功率命令一起发送时，该方法可能是特别有利的。
