摘要： Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.

摘要： Apparatus and methods for time division based communication between a wireless device and a wireless network in a licensed radio frequency (RF) band and an unlicensed RF band are disclosed. The wireless device receives downlink control information (DCI), via a primary component carrier (PCC) of a primary cell (Pcell) in the licensed RF band, indicating downlink (DL) data transmission via a secondary component carrier (SCC) of a secondary cell (Scell) in the unlicensed RF band. The wireless device receives via the SCC part of the DL data transmission and transmits a control message via the PCC in response. The wireless device sends a scheduling request (SR) to the eNodeB and receives uplink (UL) transmission opportunities in a combination of the licensed RF band and the unlicensed RF band. The wireless device performs a clear channel assessment before reserving and transmitting to the eNodeB in the unlicensed RF band.

摘要： The disclosure describes procedures for allocating network resources for a mobile device communicating within a Long Term Evolution (LTE) network. The mobile device can be configured to decode a physical downlink shared channel (PDSCH), acquire first and second physical downlink control channel (PDCCH) decode indicators from a payload of the same PDSCH communication, decode a PDCCH for downlink control information (DCI) associated with a first application data type based on the first PDCCH decode indicator a second application data type based on the second PDCCH decode indicator. The first PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated VoLTE resource assignments and the second PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated with high bandwidth best effort (BE) data resource assignments.

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

摘要： A method for determining whether an acknowledgement received by a user equipment from an external device is a forced acknowledgement. The method including transmitting a set of data stored in an uplink buffer to an external device, receiving an acknowledgement from the external device, determining if the acknowledgement received from the external device was a forced acknowledgement and flushing out an uplink buffer if determined that the acknowledgement was not a forced acknowledgement. The determining the acknowledgement is a forced acknowledgment being based on whether an uplink retransmission collides with one or more scheduled transmission times, a Physical Hybrid-ARQ Indicator Channel (PHICH) falls between gap measurements and an uplink retransmission collides with one of the gap measurements or a TTI bundling retransmission collides with a gap measurement. If the acknowledgement is not a forced acknowledgment, a set of data stored in the uplink buffer is retransmitted to the external device.

摘要： In order to reduce power consumption of an electronic device during wireless communication, the electronic device may transition between a baseline (simple) receiver and a higher-power advanced receiver based on network conditions and/or environmental conditions. For example, the transition to the advanced receiver may occur when it offers improved communication performance over the baseline receiver, such as when there is significant interference and a high data rate, or when there is significant interference and a signal-to-noise ratio (SNR) is low. Similarly, the transition to the baseline receiver may occur when the capabilities of the advanced receiver are not needed, such as when there is less interference, or when the data rate is lower and the SNR is high. In this way, the electronic device can avoid the added power consumption associated with the advanced receiver except where the communication performance offered by the advanced receiver is needed.

摘要： Methods and apparatus for interference coordination to improve transmission and reception performance within wireless networks. In one exemplary embodiment, a wireless transmitter transmits multiple transmissions over a determined time. The receiver receives the multiple transmissions and attempts to recover the transmitted signal. Because, the fading channel varies over time for each transmitter-receiver, by combining the received signals over multiple iterations, the signal of interest will be magnified, whereas interference effects will be suppressed.

摘要： Apparatuses may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements may be gathered using the antennas and corresponding signal strength difference measurements may be produced to reflect which of the antennas is exhibiting superior performing. Information may be gathered relating to the fading environment of the communications circuitry, such as whether the wireless communications circuitry is transitioning between a fast fading environment and a slow fading environment. For example, the wireless communications circuitry may further include a satellite positioning system receiver or an accelerometer, which may be used in gathering the information. The difference measurements may be filtered and compared to antenna switching criteria such as antenna switching thresholds. An antenna switching threshold may be adjusted in real time based at least in part on the gathered information.
