Abstract: Aspects described herein relate to indicating, to a base station, to use a separate uplink beam that is different from a downlink beam in transmitting uplink communications, and transmitting uplink communications to the base station based on the separate uplink beam. Additional aspects can relate to performing beam failure detection for the separate uplink and downlink beams.

Abstract: Methods, systems, and devices for wireless communications provide for identification of multiple antenna panels at a user equipment (UE), and determination of panel-specific capabilities for the multiple antenna panels. A UE may determine whether simultaneous communications using two or more antenna panels is supported. The UE may determine that simultaneous communications using two or more antenna panels is supported based on a predetermined rule that indicates such simultaneous communications are supported or unsupported. Whether simultaneous communications on multiple panels is supported may be dependent upon a capability of the UE. The UE may transmit panel-specific capabilities to the base station, that may be used by the base station for subsequent communications between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a multi-slot downlink transmission, that a mapping from a transmission configuration information (TCI) state index to a first TCI state configuration has changed to a second TCI state configuration. The UE may select, based at least in part on the determined change, the first TCI state configuration or the second TCI state configuration to use for at least a portion of the multi-slot downlink transmission. The UE may receive the multi-slot downlink transmission during one or more slots according to the selected TCI state configuration and the TCI state index.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control information indicating a resource allocation pattern for a downlink transmission that is configured for transmission using a plurality of beams and a plurality of mini-slots, where a duration of a mini-slot is less than a duration of a slot. The UE may identify a start time of a first mini-slot of the plurality of mini-slots and a length of the first mini-slot based on the resource allocation pattern, and receive the downlink transmission based on the start time of the first mini-slot and the length of the first mini-slot.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless node (e.g., a vehicle mounted integrated access and backhaul (IAB) node) may aid in wireless communication between one or more wireless devices operating in a high-speed environment (e.g., on a high-speed train (HST)) and one or more network entities. The wireless node may transmit one or more reference signals associated with a Doppler estimation procedure to the one or more network entities. The network entities may use the one or more reference signals to generate a set of Doppler compensation parameters to use while communicating with the wireless node and the one or more wireless devices. In some examples, the wireless node may receive control information or data from the one or more wireless devices, aggregate the information, and transmit the aggregated information to the one or more network entities on behalf of the wireless devices.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving, from a network node, a message that indicates for the UE to generate a periodic channel state information (CSI) report including refinement information with respect to a previously CSI report. The UE may receive one or more demodulation reference signals (DMRSs) during one or more semi-persistent scheduling (SPS) occasions and generate the CSI report, where the refinement information included in the CSI report is based on measurements of the received one or more DMRSs. The UE may then transmit the CSI report to the network node.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam management enhancements in model-based channel tracking are disclosed herein. An example method for wireless communication at a first network entity includes receiving from a second network entity, a model configuration indicative of a model condition of a channel between the first network entity and the second network entity for multiple beam pairs. The example method also includes tracking a variation in a channel condition relative to the model condition of the channel based on the model configuration for each of multiple beam pairs separately in multiple tracking sessions that overlap in time. Each beam pair may include a transmission beam and a reception beam.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a list of transmission configuration indicator (TCI) state patterns where each entry in the list may correspond to a different TCI state pattern. The base station may transmit an indication of a selected entry from the TCI state pattern list and transmit a grant to the UE indicating that resources have been allocated in for transmitting a transport block (TB). The UE may receive the grant and attempt to receive the TB in accordance with the indicated TCI state pattern. The UE may generate multi-bit feedback to indicate whether the UE was able to successfully decode the TB and transmit the feedback to the base station. The base station may use the multi-bit feedback for determining whether to select a different TCI state pattern.
