摘要： Techniques to support multihop relay in a wireless communication system are described. In an aspect, a relay station receives data and a first pilot from an upstream station, e.g., a base station or another relay station. The relay station derives a channel estimate based on the first pilot and performs detection for the data based on the channel estimate. The relay station resends the data and sends a second pilot to a downstream station, e.g., a subscriber station or another relay station. Each pilot may be sent in accordance with a pilot format selected for that pilot. The first and second pilots may be sent using the same or different pilot formats. The relay station may receive channel information from the second station and may forward the channel information to the first station and/or select a rate for data transmission to the second station based on the channel information.

摘要： Systems and methodologies are described herein that facilitate computation of composite priorities for composite events associated with a multi-radio wireless device. As described herein, respective priority values can be assigned to composite events (e.g., radio events associated with a plurality of distinct radios) in a variety of manners. Upon assignment of priority values, a radio coexistence manager and/or other suitable means can be utilized to selectively grant respective events from among a set of events that are identified within the same time period. In various examples described herein, priorities can be computed for composite events such that relative priorities of composite events are higher if the constituent atomic events of the composite events have higher priorities, such that the relative priority of a composite event is greater than the priority of any subset of its events, and/or according to any other suitable criteria.

摘要： Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.

摘要： In a power control messaging scheme for wireless communication, a wireless node sends vectorized information to another wireless node that uses the information to control its transmit power. In some aspects, the vectorized information may relate to interference observed at a wireless node. In some aspects, the vectorized information may relate to power adjustment offsets. In some aspects, the information may be vectorized based on one or more of different quality of service classes, different assignments within a frame, different permutation zones, different channel differences, different locations of a wireless node, different channel types, different other sector interference values, and different assignment sizes. In some aspects, a wireless node transmits a power control message via an uplink map in an assignment message.

摘要： Techniques for transmitting data with distributed and centralized scheduling in a multihop relay communication system are described. For distributed scheduling, a relay station may generate and send first channel quality information (CQI) to a base station and receive second CQI from a subscriber station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on the second CQI. For centralized scheduling, the relay station may generate first CQI for the base station, receive second CQI from the subscriber station, and send both CQIs to the base station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on a scheduling decision determined based on the second CQI. Techniques for distributed and centralized power control are also described.
