Abstract:
Various arrangements for managing wireless network communication are described. Two cells using different radio access technologies (RATs), such as a 3G cell and a 4G cell, may provide overlapping coverage. A first cell using a first RAT, under certain circumstances, may be permitted to enter a powered down state such that less power is consumed. User equipment may communicate with the cell using the second RAT as the preferred network and only communicate with the cell using the first RAT when a service available through the first RAT but not the second RAT has been requested. Upon a request from the second cell, the first cell may enter a powered up state.
Abstract:
A scheme is provided for conserving power in client terminals and/or reducing latency in wireless systems by using a proxy device. The client terminal may have a primary communication interface for communications with an access node and a secondary communication interface to communicate with the proxy device. The client terminal may indicate to the access node a short cycle rate for monitoring its signaling/control channel(s). The client terminal may the power off its primary communication interface without informing the access node. Prior to powering off its primary communication interface, the client terminal may assign the proxy device to act as its proxy and monitor the signaling/control channel with the access node. The proxy device monitors the signaling/control channel(s) according to the indicated short cycle rate. Upon detection of a message for the client terminal, the proxy device forwards the message to the client terminal via a secondary communication interface.
Abstract:
A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal, having a low-power communication interface and a high-power communication interface, may power down its high-power communication interface, to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a host terminal to act as a proxy for the client terminal. The host terminal monitors the paging channels for the client terminal via a high-power communication interface. If the host terminal detects a paging message for the client terminal, it forwards at least a portion of the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message from the host terminal via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to an access terminal that initiated the paging message.
Abstract:
A method of and system for calibrating a repeater in a wireless communications system are provided. The one or more calibration parameters for the repeater are derived from (a) time measurements derived from one or more signals relayed by the repeater and received at a plurality of different measurement positions, and (b) the positions of the measurement locations. In one application, the one or more parameters are used in determining the positions of subscriber stations in the wireless communications system.

A method comprises establishing a session between a host and a display unit, including transmitting media content according to a television broadcasting standard, and implementing control traffic for the session on a bi-directional control link independent of the television broadcasting standard.
Abstract:
Embodiments describe manufacturing, programming, testing, and servicing of wireless computing devices utilizing their embedded wireless technology. An embodiment method ensures that the wireless computing devices are successfully programmed in the event a disruption to the manufacturing, programming, testing and servicing process flow occurs. The method includes retrieving a last known location of the wireless device before the disruption event and comparing the last known location with the location of the wireless of the wireless device after the disruption event. A wireless device may be returned to the last known location before the disruption event if there is a difference in locations. The programming at the last known location before the disruption event occurred may be successfully completed. Further embodiments include configuring the manufacturing, programming, testing, and servicing of wireless computing devices utilizing the embedded wireless technology in the device based on a reported location of the device within a facility.
Abstract:
A method for concurrent bandwidth aggregation (COBA) for a client via multiple wireless networks includes requesting a packet data session for a first path on a first wireless network using a first modem of the multi-modem UE via a packet core network of the first wireless network. The method further includes requesting a packet data session for a second path on a second wireless network via the packet core network of the first wireless network using a second modem of the multi-modem UE. The method also includes receiving packet data over at least the second path on the second wireless network via the packet core network of the first wireless network.
Abstract:
A method and apparatus for generating and use of a position location reference signal that allows a receiver to receive position location signals from relatively weak signal generators when in the presence of a strong signal source. The position location reference signals from multiple sources can be synchronized to occur within a scheduled time slot of a time division multiplexed communication system. During the scheduled time slot, each signal source can configure a transmission that includes a media access control address that corresponds to a value reserved for position location signals. Each signal source also configures the transmission to include a position location reference signal that corresponds to the signal source. The position location signals from each of the signal sources is positioned to occur at a time within the data portion of the scheduled time slot that no neighboring signal source transmits its corresponding position location signal.
Abstract:
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.
Abstract:
A method for providing wireless communication services via efficient management of frequency bands includes transmitting uplink communications to a first system on a first frequency. The method also includes receiving downlink communications from the first system on a second frequency. The method may also include transmitting uplink communications to a second system by re-using the second frequency. The method further includes receiving downlink communications from the second system by re-using the first frequency.
