Abstract: A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1×RTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1×RTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1×RTT and DO beacons for all access terminals entering the base station coverage.

Abstract: Techniques for switching user equipments (UEs) between wireless systems are disclosed. A UE may be located within the coverage of a plurality of wireless systems and may communicate with a first wireless system among the plurality of wireless systems. The plurality of wireless systems may include a WLAN system and a cellular system and/or may be part of a small cell. Metrics of the UE for the plurality of wireless systems may be determined. The metrics may be related to one or more of efficiency, service charge, service subscription, application type, or buffer size. Whether to switch the UE from the first wireless system to another wireless system may be determined based on the metrics. In one design, switching priorities of the UE for the plurality of wireless systems may be determined based on the metrics and may be used to determine whether to switch the UE.

Abstract: A system for self-configuration of power control parameters based on path-loss is operable by a network entity that determines a default power parameter for an access terminal. The network entity determines a path-loss difference between a first path-loss for the access terminal to a serving cell and a second path-loss for the access terminal to a neighboring cell. A power control parameter is determined based on the default power parameter and the pass-loss difference. A system for self-configuration of power control parameters based on downlink power is operable by a network entity that determines a default power parameter for an access terminal. The network entity determines a downlink power difference between a downlink power of a serving cell and a downlink power of a neighboring cell. A power control parameter is determined based on the default power parameter, the downlink power difference.

Abstract: Systems and methods are provided for optimizing resource usage by a network entity that detects a first channel condition for a first radio access technology (RAT) and a second channel condition for a second RAT. The network entity determines whether the first channel condition comprises a higher interference level than the second channel condition and also determines power consumption constraints. If the first channel condition comprises a higher interference level than the second channel condition, the network entity reassigns at least one antenna from the first RAT to the second RAT based at least in part on the power consumption constraints. In some embodiments, systems and methods are also provided for determining whether an access point serving an access terminal is a large cell base station or a small cell base station and determining a power management action for the access terminal.

Abstract: Information is communicated between access points to cause a recipient access point to invoke an action. In some aspects, a mapping is defined between: 1) sets of physical layer identifiers and/or associated time offsets; and 2) different types of information. The mapping information is provided to access points in a wireless communication system such that an access point can use this scheme to communicate specified types of information to another access point. Based on the mapping, an access point that receives a set of physical layer identifiers from another access point is able to determine the type of information being communicated. The recipient access point may then invoke a specific action based on the type of information that was communicated.

Abstract: Confusion associated with a physical layer identifier is detected and action taken to address this confusion. In some aspects, confusion detection involves determining whether signals such as beacons or pilots that are associated with the same physical layer identifier are also associated with different timing (e.g., different observed time difference (OTD) values). In some aspects, confusion detection involves determining whether an inordinate number of handover failures is associated with a particular physical layer identifier. In some aspects, the action taken upon detecting physical layer identifier confusion involves ensuring that an access terminal is not handed over to an access point that uses that physical layer identifier. In some aspects, the action taken upon detecting physical layer identifier confusion involves resolving the confusion.
