    Abstract: A user equipment (UE) may reduce coexistence issues with one or more radio access technologies (RATs) caused by a bursty interference. The bursty interference may be detected by detecting a number of modes in a measured signal sample and determining when a signal contains a multi modal distribution based at least in part on the detecting. A coexistence indication is created based at least in part on the determining.

    Abstract: 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.

    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.

    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: 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.
