  • Patent number: 8285285
    Abstract: Systems and methodologies are described that facilitate utilizing reselection indicators in reselecting access points in wireless communications. In particular, an indicator can be provided relating to a restricted association access point that specifies whether intra-frequency reselection is allowed. If so, a mobile device receiving the indicator can reselect to other access points, to which it has access, operating in a similar frequency. If not, the mobile device can evaluate access points in other frequencies so as not to cause substantial interference to the restricted association access point. In addition, a predicted level of interference caused by communicating with an intra-frequency access point can be computed and evaluated to override the reselection indicator, in some cases. Thus, a restricted association access point can control reselection for some devices to mitigate interference while allowing the devices to override prohibitive restricted access points.

  • Patent number: 8213405
    Abstract: Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.

  • Patent number: 8204505
    Abstract: Systems, methodologies, and devices are described that manage employment of network (NW)-initiated resource allocation and user equipment (UE)-initiated resource allocation for a UE. To employ NW-initiated resource allocation, a core network can transmit an indicator to the UE indicating that Policy and Charging Control (PCC) is supported by a network associated with the UE. The UE receives the indicator and other information, such as indicator regarding whether the current access network supports NW-initiated resource allocation and whether the current application prefers NW-initiated resource allocation, determines that NW-initiated resource allocation is to be employed, and the core network initiates resource allocation for the UE. If any indicator is not received by the UE, or the UE receives an indicator that indicates PCC is not supported or not preferred, the UE determines that UE-initiated resource allocation is to be employed, and transmits a request for resource allocation to the core network.

  • Patent number: 8199758
    Abstract: Depending on channel conditions, a variable abort timer can be set in relation to wireless communication of data packets. Additionally, available buffer size can be evaluated and used to set a length of the variable abort timer. When a packet sequence is sent, packets can become lost in communication. When a lost packet is recognized, the timer can be initiated and a request for re-transmission of the lost packet can is sent. If the lost packet does not arrive during running of the variable abort timer, then the packet sequence can be processed without the missing packet.

  • Patent number: 8059595
    Abstract: In a communication system in which a gateway entity is linked to a plurality of infrastructure entities which in turn are operable to communicate with an access terminal, the access terminal needs first to establish a data attachment point (DAP) with one of the infrastructure entities. Handoff of the DAP from one infrastructure entity to another infrastructure entity is initiated by the access terminal. The access terminal weighs factors such as the link conditions with the various infrastructure entities, the time since the last DAP handoff, and time duration communicating with the current infrastructure entity before proceeding with the DAP handoff.

  • Patent number: 8031622
    Abstract: In a communication system (100) for decoding a quick paging channel (QPCH), a receiver (200) determines a channel condition of a pilot channel received at a mobile station (102-104). A control system (210, 401) determines receive diversity at the receiver (200) by determining a number of a plurality of receiver chains (290) in the receiver (200) for receive diversity based on the determined channel condition. The receiver (200) determines a first data bit of the QPCH in accordance with processing of one or more signals produced based on the determined receive diversity. The control system (210, 401) is configured for reducing the number of selected receiver chains (290) when the determined channel condition is above a first channel condition threshold (601) and increasing the number of selected receiver chains (290) when the determined channel condition is below a second channel condition threshold (602).
