Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

Abstract: The present application at least describes a frame structure in new radio. The frame structure includes a self-contained transmission time interval. The transmission time interval includes a control information region including plural beams. The interval also includes a downlink transmission channel region including plural beams. The frame structure is configured for downlink control information to be swept through the time interval. The frame structure is also configured for an uplink or downlink grant resource subsequently to be swept through the time interval. The present application is also directed to a method for configuring user equipment.
