Abstract: This disclosure provides methods, devices and systems for reducing power consumption when a station (STA) is operating in a listen mode. In some aspects, to reduce power consumption in the listen mode, the STA may alternate between monitoring a wireless channel for packets and not monitoring the wireless channel. When the STA is monitoring the wireless channel for packets in the listen mode, the STA may configure packet detection components to a power-on state. When the STA is not monitoring the wireless channel in the listen mode, the STA may configure packet detection components to a power-off state. During the power-on state of the listen mode, the STA may detect a preamble of a packet that was transmitted over the wireless channel. In response to detecting the preamble of the packet, the STA may switch from the listen mode to a receive mode to process the packet.

Abstract: A method for apportioning uplink transmission power in a mobile communication device is disclosed including determining a maximum power limit for the mobile communication device, identifying a first wireless transmission scheduled to transmit at a first power and a first time according to a first radio access technology (RATI); identifying a second wireless transmission scheduled to transmit at a second power and a second time according to a second radio access technology (RAT2). An aggregate transmission power required for transmission is calculated and transmission is apportioned asymmetrically as to at least one of power and/or time between the first wireless transmission and the second wireless transmission where the required aggregate transmission power exceeds said maximum power limit. Transmitting at least one of said first and/or second wireless transmission according to said asymmetrical apportionment results in transmission within specified power limits.

Abstract: A user equipment (UE) is equipped with multiple subscriber identity modules (SIMs). The UE identifies a situation requiring selection of a cell to camp on for a first SIM configured to operate using a first mobile network of a first network operator. The UE checks whether the UE is in a coverage hole of the first mobile network. If the UE is not in a coverage hole, the UE camps the first SIM in a cell of the first mobile network. If the UE is in a coverage hole, the UE determines whether any other SIM is already camped on a cell with support for limited service. If there is such other SIM, the UE suspends selection of the cell for the first SIM. Otherwise, the UE camps the first SIM on any acceptable cell for limited service.

Abstract: Devices and methods for determining timing offsets between wireless devices are provided. One method includes transmitting, from a first device, a request for timing data to first user equipment and receiving a response. The timing data is indicative of a frame timing associated with a reference time for both the first device and a second device. The method further includes determining a timing offset between the frame timing for the first device and a frame timing for the second device based on the timing data. Another method includes receiving a reference time from a timing reference device, applying a timestamp to frame timing data for the first device, receiving frame timing data from the second device time-stamped based on the reference time, and comparing the timing data to determine a time offset between the devices.

Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.
