Abstract: Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, etc. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, etc. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points and/or groups to make the determination.

Abstract: Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell- specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning sub frames. Resource elements within the positioning sub frame can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

Abstract: Se describen sistemas y metodologías que facilitan la temporización de la sincronización entre nodos en una red de comunicación inalámbrica; un nodo inalámbrico de rastreo puede sincronizarse a una señal de sistema de posicionamiento global (GPS) en caso de estar disponible; de manera alternativa, el nodo inalámbrico de rastreo puede recibir métricas de calidad relacionadas con uno o más nodos objetivo; las métricas de calidad pueden relacionarse con parámetros que pueden ser utilizados para evaluar el nodo objetivo para sincronización de temporización; con base en las métricas de calidad, el nodo inalámbrico de rastreo puede seleccionar un nodo inalámbrico objetivo para sincronización de temporización; el nodo inalámbrico de rastreo posteriormente puede sincronizar la temporización con el nodo inalámbrico objetivo; además, el nodo inalámbrico de rastreo continuamente puede evaluar los nodos inalámbricos circundantes para detectar si otros nodos inalámbricos tienen métricas de calidad más elevada que los nodos inalámbricos objetivo actuales y, por consiguiente, pueden re-sincronizarse con nodos que tienen métricas superiores.

Abstract: Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

Abstract: Techniques for sending low reuse preambles in a wireless network are described. In an aspect, a base station sends a low reuse preamble on reserved frequency resources to allow terminals to detect the base station even in the presence of strong interfering base stations. The base station generates the low reuse preamble to include a pilot portion and a data portion. The base station determines frequency resources reserved for sending low reuse preambles by base stations. The base station then sends the low reuse preamble on the reserved frequency resources, e.g., at a pseudo-randomly selected time. A terminal detects for low reuse preambles sent by the base stations on the reserved frequency resources. The terminal recovers information for a base station from a detected low reuse preamble.

Abstract: Techniques for mitigating interference on control channels in a wireless communication network are described. In an aspect, high interference on radio resources used for a control channel may be mitigated by sending a request to reduce interference to one or more interfering stations. Each interfering station may reduce its transmit power on the radio resources, which may then allow the control channel to observe less interference. In one design, a user equipment (UE) may detect high interference on radio resources used for a control channel by a desired base station. The UE may send a request to reduce interference on the radio resources to an interfering base station, which may reduce its transmit power on the radio resources. The UE may receive the control channel on the radio resources from the desired base station and may observe less interference from the interfering base station.

Abstract: An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.
