Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: A configurable new radio (NR) uplink (UL) transmission may use transmit diversity. A user equipment (UE) may identify an uplink transmission of at least one stream as using one of cyclic prefix orthogonal frequency division multiplexing or discrete Fourier transform spread orthogonal frequency division multiplexing. The UE may apply a precoding matrix to the at least one identified stream. The precoding matrix changes over time. The precoding matrix may change based on closed loop feedback, a precoding cycling pattern, and/or a code division multiplexing group. The UE may transmit the at least one identified stream from multiple antennas according to the applied precoding matrix.

Abstract: Certain aspects of the present disclosure provide techniques that may be used for low latency communications. For example, aspects allow a single group acknowledgement to be used to acknowledge a plurality of low latency transmissions. An exemplary method generally includes receiving, from a base station, a plurality of downlink channel transmissions, wherein each of the downlink channel transmissions is sent using a first transmission time interval (TTI) that is reduced relative to a legacy TTI and providing, in a single uplink channel transmission sent using a second TTI that is larger than the first TTI, a group acknowledgement indicating whether or not the downlink channel transmissions were successfully received by a UE.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). Additionally, certain aspects of the present disclosure provide techniques for managing communications in a wireless communication system, for example, by using enhanced downlink control channels.

Abstract: A method for communication includes a user equipment (UE) periodically awakening to monitor for a wake-up signal (WUS) in a wake-up signal search space, the wake-up signal having a shorter length than a length of a control channel communication to allow the UE to determine whether the UE should monitor for the control channel communication.

Abstract: Aspects herein describe determining a channel format for transmitting uplink communications in a slot, wherein the channel format is selected from multiple channel formats based at least in part on a payload size of the uplink communications, determining a starting symbol and an ending symbol of an uplink channel duration of the slot for transmitting the uplink communications, determining, based at least in part on the starting symbol and the ending symbol, a portion of the channel format to utilize in transmitting the uplink communications in the slot, and transmitting the uplink communications in the slot, wherein transmitting the uplink communications is based on the portion of the channel format.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.
