  • Patent number: 10716133
    Abstract: The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

  • Patent number: 10708853
    Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

  • Publication number: 20200213982
    Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing a control channel (PDCCH) design. The PDCCH can occupy an initial number of OFDM symbols of a downlink subframe, while occupying less than the full system bandwidth. The PDCCH can be time division multiplexed (TDM) with a shared channel (PDSCH) or frequency division multiplexed (FDM) with a PDSCH. The PDCCH can further be multiplexed with another PDCCH in a contiguous or non-contiguous region. Resources allocated to the PDCCH can overlap or partially overlap resources allocated to the PDSCH. An Evolved Node-B (eNB) can provide configuration information for the PDCCH design in Radio Resource Control (RRC) signaling to a user equipment (UE), or through use of a Master Information Block (MIB) or System Information Block (SIB).

  • Publication number: 20200186263
    Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.
