摘要： When a user equipment (UE) is communicating wirelessly over a wireless communication network and terminates wireless communication temporarily due to power limit constraints (such as to satisfy a specific absorption rate (SAR) threshold), the UE may maintain its radio access network (RAN) identification (ID) and domain context, in order to quickly resume wireless communication, and avoid upper layer connection setup, once the UE is no longer power limited.

摘要： Systems and methodologies are described that facilitate random access procedures using one or more fallback access schemes after initial access attempts have failed. UE equipped to determine failure of a first access request to a first base station due to interference from a second base station. Further, a UE equipped to determine the failure can do so and implement one or more fallback access schemes in response to the determination. In one example, a fallback access scheme allows the UE to select a secondary carrier frequency for communications with the first base station. In another example, a fallback access scheme allows the UE to designate the first base station as inaccessible and communicate with other base 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： Mobile terminals in a high data rate CDMA system may be placed in a control hold mode wherein reverse link control channels are gated, or transmitted at a reduced duty cycle. Mode decisions are based on the activity of the mobile terminal in both the forward and reverse links. A forward link inactivity timer is maintained at the base station that schedules forward link communications to a mobile terminal. The reverse link inactivity timer may be maintained at the same base station, at a different base station in the mobile terminal's active set, or at the base station controller. The forward link inactivity timer may follow the mobile terminal's selection of best forward link serving base station in handoff. When both the forward and reverse link inactivity timers have expired, and no forward link data is pending, the mobile terminal may be commanded to a control hold mode.

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： A communication station employs discontinuous transmission of channel quality feedback to reduce channel quality feedback transmitted over overhead channels. Prior to transmitting channel quality information to a remote station, the communication station compares the channel quality feedback to predetermined qualification criteria. If the qualification criteria are not met, the channel quality feedback is not transmitted. The method may be implemented by a mobile station to reduce channel quality feedback sent to a base station over a reverse link overhead channel.

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.
摘要翻译：无线通信系统中的用户被提供到基于QoS的类别中，并使用单个每扇区通用速率控制（CRC）子信道进行速率控制。在一个或多个实施例中，不同的移动站被配置为通过用不同的业务对导频比（TPR）表和/或不同的TPR步长调整表来为相同的CRC命令作出不同的响应。也就是说，网络可以通过向属于特定类别或组的移动站发送类别或组特定TPR相关值来定义不同类别或移动站组。使用这种方法，即使两个组都接收到相同的速率控制命令，一组中的移动站可以实现与另一组中的移动站不同的反向链路数据速率，或者使得更积极的数据速率改变。

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。
