Abstract: PROBLEM TO BE SOLVED: To provide a messaging scheme for controlling transmit power of wireless device.SOLUTION: 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.

Abstract: PROBLEM TO BE SOLVED: To transmit data with distributed scheduling and centralized scheduling in a multihop relay communication system.SOLUTION: 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. Distributed and centralized power controls are also performed.

Abstract: Power control for wireless communication may involve determining the transmit power to be used by a wireless device. A wireless device using open loop power control may select a transmit power based on an open loop power equation where a parameter of the power equation may be based on one or more power control messages received from another wireless device. In some aspects, path loss may be estimated for open loop power control and a value for Offset_BSperSS may be obtained from information provided by a base station for closed loop power control. To facilitate a stable combined open-closed loop algorithm, open loop power control may be used to compensate channel changes based on reciprocity, and closed loop power control may be used to compensate interference variations (e.g., as compared to NI provided by a DCD message).

Abstract: 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.

Abstract: Automated PilotPN code conflict resolution using an access point with the assistance of one or more access terminals is disclosed. An exemplary method includes determining a set of access points, as well as determining a set of PilotPN codes used by the set of access points. Detection is then made concerning whether at least two access points of the set of access points have conflicting PilotPN codes. A first PilotPN code is allocated to one of the at least two access points having conflicting PilotPN codes. Additionally, one or more other PilotPN codes, which are distinct from the first PilotPN code, are allocating to remaining access points of the at least two access points having conflicting PilotPN codes. Corresponding apparatus and other exemplary methods are also disclosed.
