The accessory device can begin the page scan at the predetermined time and can receive pages from a host device during a page scan window of the page scan over the wireless medium. The received pages can then be subsequently used to establish an ad hoc network connection between the accessory device and the host device. | 2020-04-16 |
20200120724 | APPARATUS AND METHODS FOR CELL IDENTIFICATION IN WIRELESS NETWORKS - Apparatus and methods for physical cell identification within one or more wireless networks. In one embodiment, conflicts in PCI values which may exist within two or more mobile networks (e.g., PLMNs) of respective different operators when unlicensed spectrum is utilized (e.g., according to 3GPP 5G NR-U technology) are resolved. In one implementation, this functionality is provided by specifying one or more mobility-related parameters associated with various UE, such that serving gNBs can determine whether a given UE requires a mobility context, and as such whether it should conduct subsequent RF measurement reporting to report back potential conflicts in PCI it may encounter to the gNB. In one variant, the measurement reporting is configured to comply with 5G NR-U required “listen-before-talk” or LBT protocols; i.e., to measure parameters consistent with the LBT protocols to detect any such PCI-based conflicts. | 2020-04-16 |
20200120725 | Internet Protocol (IP) Address Assignment in Integrated Access Backhaul (IAB) Networks - Embodiments include methods and/or procedures performed by an integrated access backhaul, IAB, node of a radio access network, RAN, that is associated with a core network, CN. Such embodiments include performing a registration with a CN node, and establishing a secure connection with a RAN node. Such embodiments also include receiving, from the RAN node via the secure connection, configuration information for one or more radio bearers between the IAB node and the RAN node. The radio bearers are adapted for backhaul of control plane information and/or user plane information. Such embodiments also include establishing, with the RAN node via at least one of the radio bearers, one or more Internet Protocol addresses usable by the IAB node. Other embodiments include complementary methods and/or procedures performed by CN nodes and RAN nodes, as well as network nodes configured to perform the various methods and/or procedures. | 2020-04-16 |
20200120726 | Mechanism for Realizing LWA/LWIP Aggregator Function - In one implementation, the method comprises, in response to obtaining a request to associate an electronic device with the one or more WLAN termination nodes: generating, between a base station and a networking device, a control link based on a first identifier associated with the base station; generating, between the networking device and a first WLAN termination node, a control link based on a second identifier that corresponds to a pseudonym for the base station; and associating the first and second identifiers in a control table. The method further comprises: instantiating, between the base station and the networking device, a first data tunnel associated with a first tunneling protocol; instantiating, between the networking device and the first WLAN termination node, a second data tunnel associated with a second tunneling protocol; and associating the first and second data tunnels. | 2020-04-16 |
20200120727 | BIDIRECTIONAL SENDING AND RECEIVING OF WIRELESS DATA - A system and method includes a first audio device (e.g., a primary wireless earbud) connected to a second audio-output device (e.g., a secondary wireless earbud) using a first wireless connection. The first audio device is also connected to a user device (e.g., a smartphone or smart watch) using a second wireless connection. The second audio device receives data, such as packets, sent from the third device to the first device by monitoring the second wireless connection. If the second audio device does not determine that the first audio device sent a corresponding acknowledgement message (i.e., the first audio device did not receive a packet), the second audio device sends the acknowledgement message and sends the packet to the first audio device. | 2020-04-16 |
20200120728 | Radio Resource Control Connection Establishment - A method for establishing a radio resource control connection between a first wireless device and a radio network node, comprises transmitting a request for a radio resource control connection towards the radio network node from the first wireless device to a second wireless device. Then, the second wireless device forwards the request for a radio resource control connection towards the radio network node to the radio network node. The forwarding by the second wireless device uses an already established radio resource control signaling connection between the second wireless device and the radio network node. | 2020-04-16 |
20200120729 | METHOD FOR DEVIC TO DEVICE COMMUNICATION, TERMINAL DEVICE AND NETWORK DEVICE - The present disclosure discloses a method for D2D communication, a terminal device and a network device, where the method includes: determining, by a terminal device, a resource pool for data transmission from a plurality of resource pools according to a transmission mode used by the terminal device and whether the terminal device has a sensing capability, where different resource pools in the plurality of resource pools are used for data transmission by different types of terminal devices, and at least one of the following information of the different types of terminal devices is different: a transmission mode in use, a supported version of a communication protocol, and whether or not there is the sensing capability; performing, by the terminal device, data transmission using a time-frequency resource in the resource pool. Therefore, different types of terminal devices can transmit data together in a communication system and mutual interference is reduced. | 2020-04-16 |
