Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to control resource sets (coresets) for transmitting physical downlink control channels using either a single-carrier waveform or a multicarrier waveform in communications systems operating according to new radio (NR) technologies. In an exemplary method, a base station may determine whether a control resource set (coreset), of time and frequency resources within a control region of system bandwidth and configured for a user equipment (UE), conveys a physical downlink control channel (PDCCH) via a single-carrier waveform or a multicarrier waveform, and transmit the PDCCH to the UE using the determined waveform.

Abstract: In an embodiment, a central coordination server (e.g., a Spectrum Access Server) partitions a shared communication medium into a contention-free partition where the shared communication medium is reserved for devices associated with a first set of operators and a contention-based partition where devices associated with a second set of operators contend for access to the shared communication medium, at least one operator belonging to both the first and second sets of operators. The central coordination server notifies target devices (e.g., APs, ATs, etc.) of the partitioning. In a further embodiment, a device (e.g., AP, AT, etc.) communicates over a portion of the contention-free partition that is reserved for an associated operator, and also over the contention-based partition.

Abstract: Techniques for reservation coordination on a shared communication medium are disclosed. An access point, for example, may contend for access to a communication medium, and transmit a channel reservation message in accordance with a first Radio Access Technology (RAT) to reserve the communication medium for a transmission opportunity (TXOP) duration based on the contending. The access point may then transmit, during the reserved TXOP duration, a reservation coordination signal in accordance with a second RAT to convey reservation coordination information associated with the reserved TXOP duration.

Abstract: A method for wireless communication includes determining a number of uplink data streams to transmit from a mobile device and determining a selection of antennas from a plurality of antennas for transmitting the uplink data streams. The method also includes determining beamforming parameters based at least in part on a beamforming identifier. The method further includes transmitting a first data stream via the selection of antennas in accordance with the beamforming parameters and transmitting a second data stream in response to determining that the number of uplink data streams is at least two.
