Abstract: Various aspects described herein relate to communicating using dynamic uplink and downlink transmission time interval (TTI) switching in a wireless network. A notification can be received from a network entity of switching a configurable TTI from downlink communications to uplink communications. The configurable TTI can be one of a plurality of TTIs in a frame structure that allows dynamic switching of configurable TTIs between downlink and uplink communications within a frame. Additionally, uplink communications can be transmitted to the network entity during the configurable TTI based at least in part on the notification.

Abstract: In an embodiment, an AT monitors a DMTC window of a shared communication medium while refraining from performing any AUL transmissions. The AT selectively transmits one or more AUL transmissions based on the monitoring (e.g., in response to DRS detection, either in one or more subframes of the DMTC window or outside of the DMTC window). In a further embodiment, the AT establishes different LBT contention windows for use during and outside of POWs and/or DMTC windows. In a further embodiment, the AT receives an AUL disable signal instructing the AT to disable AUL transmissions, and the AT refrains from performing one or more AUL transmissions on the shared communication medium in response to the AUL disable signal.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus reduces inference in a received signal. The apparatus receives a signal including transmissions from a plurality of cells. The apparatus determines transmission parameter hypotheses associated with the plurality of cells. Each transmission parameter hypothesis from the transmission parameter hypotheses includes a set of transmission parameters associated with all the cells from the plurality cells. The apparatus selects at least one transmission parameter hypothesis based on a first metric applied to each hypothesis. The apparatus refines transmission parameters associated with at least one cell from the plurality of cells. The refining includes improving an accuracy of the transmission parameters associated with the at least one cell based on a second metric associated with each cell individually.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive a configuration corresponding to one or more channel state information (CSI) report settings associated with a reference signal resource set. The network node may transmit at least one CSI report that indicates a primary set of CSI measurements, of a plurality of CSI measurements associated with the reference signal resource set, and a secondary set of CSI measurements of the plurality of CSI measurements, wherein the plurality of CSI measurements comprises at least one of a physical layer reference signal received power (RSRP) value or a physical layer signal-to-interference-plus-noise ratio (SINR), and wherein the primary set of CSI measurements comprises at least one of a strongest RSRP value or a strongest SINR associated with the plurality of CSI measurements. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device may receive control signaling indicating a beam configuration. The communication device may select a first beam (for example, a sensing beam) for wireless communication based on the beam configuration. The first beam including a first beam gain and a first pointing direction. The communication device may select a second beam (for example, a transmitting beam) based on the beam configuration. The second beam including a second beam gain and a second pointing direction. The communication device may determine (for example, adjust) an energy detection threshold (EDT) associated with the second beam based on the second beam gain in the first pointing direction and the first beam gain in the first pointing direction. The communication device may sense a channel using the second beam and the EDT associated with the second beam.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.
