Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that different symbol durations coexist.

Abstract: Improvements to asynchronous spatial listen before talk (LBT) procedures are disclosed. In a shared spectrum network spatial LBT procedures are used for directionally targeting the channel reservation process. Prior to transmitting channel reservation signaling, the transmitter and receiver determine an effective interference considering available multiple input, multiple output (MIMO) configuration information. When the effective interference exceeds a predefined threshold, the node may without transmission of its channel reservation signal. Otherwise, when the effective interference remains within the threshold, each node's transmitted channel reservation signal may also identify at least a beamforming matrix either as payload or used to precode the node's channel reservation signal.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication system may utilize a listen before talk (LBT) procedure prior to transmission. A base station may perform an enhanced clear channel assessment (eCCA) on one channel and a single clear channel assessment (CCA) on another channel. The base station may then send a grant for a user equipment (UE) to transmit on both channels. The UE may receive the grant, and perform a single CCA on the first channel and an eCCA on the second channel. The UE may then transmit uplink information on both the first channel and the second channel. That is, the base station may send an opportunistic grant for transmitting on the second channel even though it may not have passed eCCA at the base station. The UE may then use the channel if it passes an eCCA.

Abstract: A medium reservation framework is disclosed for coexistence of coordinated and uncoordinated wireless networks in licensed spectrum and shared spectrum. The proposed medium reservation framework organically takes into account operating regimes with different numbers of Tx/Rx antennas per node, provides flexibility in trading off medium contention aggressiveness and power saving, leverages the inherent synchronization nature of NR, and covers both coordinated and uncoordinated operation scenarios. Various aspects of the medium reservation framework may be centered on one or more combinations of some basic building blocks, such as an operation grid, synchronization signals, and reservation messages, such as a reservation request signal (RRQ) and one or more a reservation response signals (RRS).

Abstract: A method for wireless communications, comprising: signaling, to a user equipment (UE), an indication of one of at least two rules regarding how quasi co-location (QCL) configured for the UE should be applied for one or more DMRS ports; and sending downlink transmission to the UE with the one or more DMRS ports; receiving signaling from a base station and processing signals received on one or more DMRS ports based on the indicated rule. Said method improves communications between access points and stations in a wireless network.

Abstract: Methods, systems, and devices for wireless communications are described, and relate to a base station to communicating with a user equipment (UE) over a channel. A first device (for example, the base station or the UE) may use a trained neural network to estimate one or more link performance metrics associated with the channel. Predicting the link level performance may include determining one or more neural network weights associated with one or more input parameters associated with the channel to estimate the one or more link performance metrics. The first device may report feedback to the second device based on the estimated link performance metrics. Based on the feedback, the second device may adapt the link by adjusting channel parameters to improve the reliability or efficacy of later transmissions.

Abstract: Techniques are described for wireless communication. One method includes receiving, in a downlink portion of a transmission structure on a shared radio frequency spectrum band, an uplink grant for an uplink data portion of the transmission structure. The transmission structure includes the downlink portion, followed by and time domain multiplexed with an uplink control portion, followed by and time domain multiplexed with the uplink data portion. The method also includes retaining access to the shared radio frequency spectrum band by transmitting an unscheduled transmission during the uplink control portion of the transmission structure.
