摘要： Methods and apparatus for selecting a serving sector in a high rate data (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which a sector of an Access Point may send data packets to an Access Terminal. The sector is selected by the Access Terminal to achieve the highest data throughput while maintaining a targeted packet error rate. The Access Terminal employs various methods to evaluate quality metrics of forward and reverse links from and to different sectors, and uses the quality metrics to select the sector to send data packets to the Access Terminal.

摘要： Systems and methodologies are described that facilitate adjusting power spectrum density (PSD) for wireless devices according to multiple possible step sizes. A step size for an adjustment can be selected based at least in part on a received overload indicator from one or more access points, a PSD required to achieve a target signal-to-interference-and-noise ratio (SINR) for a wireless device, and a PSD previously assigned to the wireless device. Once the step size is selected, it can be applied to the previous PSD to generate a new PSD for the wireless device, and the wireless device can accordingly adjust PSD to mitigate inter-cell interference with the one or more access points.

摘要： Systems, methodologies, and devices are described that facilitate transferring a subset of compression context from a source base station to a target base station during an inter-base station handover of a mobile device to facilitate establishment of compression context between the mobile device and target base station. The source base station can transfer a subset of compression context comprising static and semi-static context to the target base station during inter-base station handover to at least partially establish compression context between the mobile device and target base station prior to or during handover. The source base station can transmit, to the mobile device, indicator information related to compression context transferred. The target base station can at least partially establish compression context based on received subset of compression context to facilitate efficient communication with the mobile device and can establish any remaining portion of compression context with the mobile device after handover.

摘要： Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.

摘要： In a wireless communications system, a serving base station performs outer and closed power control for an overhead channel and a traffic channel for data, either of which can carry an acknowledgement (Ack) channel and Channel Quality Indicator (CQI) channel on an uplink from User Equipment (UE). In an exemplary aspect, data packet communication is implemented in 3GPP LTE Rel. 8 wherein the uplink has a Single Carrier Frequency Division Multiplex (SC-FDM) uplink waveform. The UE performs open loop power control by a determining transmit power spectral density value by using received energy per symbol for a reference signal.

摘要： An access terminal (AT) in a cellular communication system is configured to operate in an active hold (AH) state, a transitional state between traffic and dormant states. The AT applies power to its transmit chain with a low duty cycle while in the AH state, conserving battery power. To improve robustness of the communications, the radio network may power control the AT to a higher level relative to the power control level of the AT in the traffic state. Transition from the traffic state to the AH state may be initiated after a brief period of inactivity on the reverse link. The AT may remain in the AH state while receiving forward link payload data. Transmission of a reverse link payload packet in the AH state may initiate transition to the traffic state. A prolonged period of inactivity may initiate a transition from the AH state to the dormant state.
摘要翻译：蜂窝通信系统中的接入终端（AT）被配置为在主动保持（AH）状态，业务和休眠状态之间的过渡状态下操作。 AT在AH状态下以低占空比向其发射链进行供电，从而节省电池电量。为了提高通信的鲁棒性，无线电网络可以将AT控制在相对于业务状态的AT的功率控制级别更高的级别。从交通状态到AH状态的转换可以在反向链路上短暂的不活动状态之后启动。 AT可以在接收到前向链路有效载荷数据时保持在AH状态。在AH状态下的反向链路有效负载分组的传输可以启动到业务状态的转换。长时间的不活动可能会从AH状态转移到休眠状态。

摘要： Techniques for rank adaptation and multiple-stream reverse link communications in a wireless access network are disclosed. A remote unit transmits one or more reverse link data streams using separate identifiers to a base station. The number of reverse link data streams may be determined according to feedback from the base station or it may be determined by testing one or more multiple-antenna transmit hypotheses. The base station may estimate channel conditions using information obtained from the one or more reverse link data streams and may determine a spatial rank of the communication channel. The remote unit may perform separate error control and power control processes for each reverse link data stream in cooperation with the base station.
