摘要:
Techniques for dynamic task distribution and processing in a wireless communication system are described. In one embodiment, the wireless communication system includes a sensor configured to measure a characteristic and to transmit information indicative of the measured characteristic. The system includes a mobile device configured to receive and aggregate the information transmitted by the sensor, perform one or more tasks related to the aggregated information, determine whether a condition necessary for transferring a subset of the tasks is satisfied, and transfer the subset of the tasks for further performance. The system further includes a local gateway device configured to receive and aggregate the information indicative of the measured characteristic from the sensor and perform tasks related to the aggregated information, receive and perform the transferred subset of the tasks from the mobile device, and transfer the tasks for further performance.

A method of facilitating communication in a wireless ad-hoc network comprises: generating, at a node in the wireless ad-hoc network, target availability information with regard to one or more transmission slots, the target availability information indicating whether the node is permitted to receive a transmission during each transmission slot; generating, at the node, owner availability information with regard to one or more transmission slots, the owner availability information indicating whether the node is permitted to transmit during each transmission slot; and broadcasting, from the node, the target availability information and the owner availability information to separately indicate availability as either an owner or a target for one or more transmission slots.

Methods and apparatuses for interference management between multiple wireless networks are disclosed. The apparatuses, and methods for doing the same, communicate with one or more wireless devices in each of first and second wireless networks, the first and second wireless networks having a common spectrum and different air interface protocols, and generate a message for transmission into the first wireless network to suppress transmission in the first network and to reserve a medium for wireless transmissions in the second wireless network.

Out of band (OOB) communication facilitates femtocell operation. One or more proximity agent provides out of band communication with nodes (e.g., mobile client devices) to provide assistance in or otherwise facilitate femtocell discovery, reselection, and/or interference mitigation. Out of band communication techniques provide for low power discovery, association, and communication as compared to corresponding femtocell or cellular network communication techniques. An OOB proximity agent is provided in association with a femtocell to provide transmit power level control with respect to the femtocell. In operation, if a client device searches for and finds an OOB proximity agent, it will find a femtocell, thereby avoiding a need to aggressively search for femtocells.

Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. A femto-proxy system is provided including a femtocell and an out-of-band (OOB) proxy. While the femtocell may be addressed by the macro network according to a potentially non-unique identifier (e.g., its PN offset), the OOB proxy is addressable according to a unique OOB identifier (e.g., a Bluetooth device address, BD_ADDR). When the mobile access terminal is in proximity to the femto-proxy system, it detects the OOB proxy and communicates the unique OOB identifier to the core network via the macro network (e.g., as part of a measurement report). The OOB identifier is mapped (e.g., in the core network) to the femtocell, allowing the core network to uniquely identify the appropriate target femtocell for active hand-in.
摘要:
Methods, systems, and devices for increasing reverse link throughput by coordination of multiple wireless systems using reverse link blanking are provided. Some embodiments involve utilizing the bandwidth of one carrier bandwidth that partially overlaps with the bandwidth of another carrier bandwidth. This overlap may create interference. Different indicators may be utilized to prompt a device, such as a mobile device, to coordinate reverse link transmission blanking on at least one of the carrier bandwidths to increase throughput for the other overlapping carrier bandwidth. For example, a base station may transmit such an indicator to the mobile device to prompt the transmission blanking. Some embodiments also include increasing transmission power for the overlapping carrier bandwidth during the transmission blanking of other carrier bandwidth. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform.
摘要:
Systems, methods, devices, and computer program products are described for mitigating macrocell interference during femtocell discovery in a wireless communications system. In one example, a mobile device may be camped on a macrocell. A femtocell transmits out-of-band (OOB) discovery signals to, or receives OOB band discovery signals from, the mobile device to facilitate presence detection. The femtocell may also be configured to use various techniques to transmit in-band beacon bursts (e.g., low or high power beacon bursts) to the mobile device in the macrocell frequency range to trigger the mobile device to perform an inter-frequency scan for cell reselection. The femtocell may transmit communications signals to the mobile device in a femtocell frequency range (different from the macrocell frequency range) after the mobile device has discovered and selected the femtocell.
摘要:
Systems, methods, devices, and computer program products are described for using an out-of-band (OOB) radio integrated with the femtocell to implement various novel proximity detection techniques. Proximity detection of access terminals (ATs) in the femtocell's access control list (ACL) can be desirable to support femto connectivity and service provision, for example, in context of idle macro-to-femto handoffs, active macro-to-femto hand-ins, etc. Implementations implement OOB proximity detection through multicasting directed proximity request messages to each AT in a femtocell's ACL. Responses to the proximity request message can include identification information used to determine the specific AT that is in proximity.
摘要:
Systems, methods, devices, and computer program products are described for refinement of femtocell coverage area information in a wireless communication system, particularly in context of a femto-proxy architecture. Zones may be defined within a femtocell coverage area using beacon sources, and a zone map of zone signatures may be defined for each zone of the femtocell coverage area, according to macro signatures detected in those zones. The zone map can be used, by access terminals, the femto-proxy system, and/or the macro network, to provide functionality, including reduced power level femtocell discovery and association, enhanced network planning, improved femtocell troubleshooting, etc.

A receiver includes a decoder configured to decode at least a portion of a data stream comprising a data frame. The data frame includes a code block having a data block and a parity block. The receiver also includes a controller. The controller is configured to determine whether to disable at least a portion of the receiver during transmission of the parity block to the receiver when the data block contains at least one erasure.
