  • Patent number: 9699784
    Abstract: An electronic device has wireless communications circuitry. The wireless circuitry may transmit and receive wireless signals over a network having first and second wireless base stations. The first base station may establish a primary wireless connection with the device using selected connection settings and may transmit the selected connection settings to the second base station. The second base station may copy the received connection settings to establish a secondary wireless connection with the device while the primary connection is simultaneously maintained. After the primary and secondary connections have been established, the first and second base stations may transmit data streams to the electronic device over different frequency bands in a carrier aggregation link. By using the second base station to copy the received connection settings that were used by the first base station to establish the primary connection, the connection time for establishing the carrier aggregation link may be improved.

  • Patent number: 9699691
    Abstract: Scheduling self coexistence windows (SCWs) that part of frames transmitted in wireless regional area networks (WRANs) sharing a common channel. A common channel is monitored for a duration of at least a maximum SCW cycle length. The common channel is checked to determine whether a neighbor WRAN scheduled at least one coexistence beacon protocol (CBP) packet with at least one of SCWs and quiet periods (QPs). A SCW schedule is established by setting SCW schedule fields in a modified superframe control header (SCH) such that the newly established SCW schedule does not conflict with any already scheduled SCWs and QPs.

  • Patent number: 9686516
    Abstract: The present invention relates to improving configuration of wireless communication paths between devices in a video projection system comprising multiple wireless video projectors. When an initial radio communication setup is required between a managing node, e.g. a node comprising a master projector, and a node comprising a slave projector, for example following the powering up of the video projection system, the slave node receives setup information by radio communication means according to a sweeping sequence and transmits information by projecting sub-images. Sub-images advantageously comprise information relative to settings of the master node allowing reception in the corresponding slave node of a radio signal transmitted by the master node.

  • Patent number: 9686049
    Abstract: A method and system for Bluetooth (BT) delayed acknowledgment is presented. Aspects of the system may include an initiator device, such as a WLAN access point (AP), which enables transmission of a protocol data unit, such as a BlockAckReq frame, to a responder device, such as a Smartphone, via a first network, for example a WLAN. The Smartphone may be equipped with capabilities that enable communication via WLAN and Bluetooth networks. The AP may wait to receive a response protocol data unit, such as a BlockAck frame, via the first network (WLAN) for a response time duration. The response time duration may be based on the communication slot time duration for communication by the Smartphone on a second network, for example a BT piconet. The communication slot time duration may correspond to the time duration for a BT slot.

  • Patent number: 9681450
    Abstract: A method for radio link control in a mobile wireless communication device. The mobile wireless device transmits a sequence of service requests to establish radio resources with a wireless communication network for a data packet in a pending data buffer. When no radio resources are allocated in response to the transmitted sequence of service requests, the mobile wireless device sets a minimum threshold for the pending data buffer, discards all pending data packets above the minimum threshold and discards the oldest pending data packet. The mobile wireless device repeats transmitting and discarding until a radio resource is allocated or the pending data packet buffer is empty. A retry interval between successive service requests is increased after transmitting each sequence of service requests until reaching a maximum retry interval value.

  • Patent number: 9674801
    Abstract: A system is provided for allocating downlink transmit power in a wireless multiple-input multiple-output (MIMO) system. During operation, the system identifies a set of receivers for receiving signals from one or more transmitters on a same time-frequency slot, receives channel state information (CSI) for communication channels between the identified receivers and the transmitters, and constructs a precoder based on the CSI. The system further derives a set of power-scale factors for the precoder based on a utility function associated with the identified receivers such that the power-scale factors optimize the utility function. A respective power-scale factor scales power transmitted to a corresponding receiver.

  • Patent number: 9674075
    Abstract: Techniques are described for enhancements to Protocol Independent Multicast (PIM) in an Any Source Multicast (ASM) mode in order to effectively implement Multicast only Fast Re-Route (MoFRR). According to the PIM ASM mode, a router operating as a last hop router connected to a receiver may initiate establishment of both a shared tree and a shortest path tree over which to receive multicast traffic for a given multicast group. According to the disclosed techniques, the router may use the shortest path tree as a primary path on which to receive the multicast traffic, and may use the shared tree as a secondary or backup path for MoFRR in case a failure occurs on the primary path. The techniques enable the router to perform MoFRR for PIM ASM mode without pruning the multicast traffic from the shared tree, and without building additional trees as secondary paths for MoFRR.
