    Abstract: Systems and methods for uplink transmission scheduling are disclosed. A wireless device may monitor at least two downlink sub-frames for scheduling grants. The wireless device may receive a first uplink scheduling grant in one of the at least two downlink sub-frames for at least a first uplink sub-frame and receive a second uplink scheduling grant in another of the at least two downlink sub-frames for at least the first uplink sub-frame. The wireless device may perform an uplink transmission in the first uplink sub-frame based on one or both of the first uplink scheduling grant and the second uplink scheduling grant. For the uplink transmission, the wireless device may select a most recent uplink scheduling grant or select an uplink scheduling grant received in a downlink sub-frame at least a minimum number of sub-frames before the first uplink sub-frame.

    Abstract: Certain aspects of the present disclosure provide techniques for improving a physical random access channel (PRACH) design, for example, to support larger cell radius for communications in a wireless network. In aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving at least one configuration of a plurality of available narrowband physical random access channel (NPRACH) configurations or an indication of one of the plurality of NPRACH configurations. Each of the plurality of NPRACH configurations includes a different combination of at least two of a multi-level frequency hopping patter, cyclic prefix length, symbol group format, or tone spacing for NPRACH signals. The method also includes determining at least one resource within a plurality of available NPRACH resources according to the received configuration(s) or the received indication, and transmitting a NPRACH signal using the determined at least one resource.

    Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.
