  • Patent number: 10321511
    Abstract: Systems, methods, and apparatuses for radio resource control (RRC) signaling in wireless communication networks with data offload are provided. The radio configuration messages from a small cell to a dual connection UE may be sent by an overlay macro E-UTRAN node-B (eNB). The small cell may send the RRC messages to the macro-eNB first via a backhaul link, and the macro-eNB then transmits the messages to the UE. In some implementations, the radio configuration messages from a small cell to a dual connection UE may be sent directly from the small cell. In some other implementations, some of the RRC messages may be sent selectively to/from either the macro-cell or the small cell, or to/from both the macro-cell and the small cell. The type of RRC messages sent over the small cell and/or the macro-cell may be preconfigured or predetermined.

  • Patent number: 10321432
    Abstract: Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.

  • Patent number: 10314062
    Abstract: A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by allocating a non-interfering downlink signaling channel for downlink reception of interference avoidance instructions at the UE device. In operation, a user equipment device detects IDC interference and sends an IDC indication message to the radio network to get an appropriate solution, but instead of waiting at the current frequency to receive the IDC response from the radio network, the user equipment device moves to a non-interfering downlink signaling channel for downlink reception of interference avoidance instructions.
