Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may transmit control information to a user equipment (UE) in a control resource set (coreset) of a transmission time interval (TTI). As described herein, the base station may transmit common control information in a common search space (CSS) of the coreset and a UE-specific control information in a UE-specific search space (USS) of the same coreset. In addition, the base station may transmit reference signals in the coreset to allow the UE to perform channel estimation to correctly decode or demodulate the control information in the CSS and USS of the coreset. In some examples, the reference signals transmitted in the CSS and USS of the coreset may include a common sequence for the coreset.

Abstract: Methods, systems, and devices for wireless communications are described that allow secondary cell (SCell) beam failure recovery using a primary cell (PCell). A user equipment (UE) may transmit, via the PCell, an indication of a beam failure of the SCell in a scheduling request (SR) or in a dedicated SR message. After receiving the indication, the base station may request a report from the UE or alternatively, may monitor a set of resources for a report without transmitting a request to the UE. The report may be transmitted via the PCell and may include an indication of a selected beam to use for subsequent communications on the SCell. Based on the report, the base station may modify its transmission configuration for the SCell and communicate with the UE via the selected beam.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may communicate with a user equipment (UE) using multiple antennas. Data streams may be mapped to the antennas using antenna ports. In some cases, a base station may transmit a transmission configuration indication (TCI) to a UE to indicate quasi co-location (QCL) relationships between antenna ports used for downlink communication with a UE. The UE may use these QCL relationships to identify appropriate techniques for decoding a downlink transmission from the base station. In some cases, it may be appropriate for a base station to update one or more TCI states configured for indicating, to a UE, QCL relationships between antenna ports used for downlink communication with the UE. As described herein, a base station may support techniques for dynamically updating such TCI states (e.g., via downlink control information (DCI) signaling).

Abstract: Methods, systems, and devices for wireless communications are described that support uplink reporting techniques for multi transmission-reception point (TRP) transmissions. Various reporting configurations may be provided that allow for user equipment (UE) communications via multiple concurrent wireless connections with multiple TRPs. A UE may identify a reporting configuration and transmit a report (e.g., a buffer status report (BSR) or a power headroom report (PHR)) to one or more of the TRPs based on the identified reporting configuration. The multiple TRPs may have non-ideal backhaul connections and the reporting configuration may allow the UE to transmit separate reports to different TRPs. The different TRPs may then use the separate reports for corresponding communications with the UE. In cases where shared radio frequency spectrum is used for communications, a single channel access priority class (CAPC) for multiple TRPs may be determined for a contention-based channel access procedure.

Abstract: A user equipment (UE) may operate in a reception mode that includes a set of sleep cycles and a set of wake cycles. During a sleep cycle of the UE, a signal quality of an active beam carrying a control channel or a data channel may degrade. This may result in the UE failing to decode the control channel or the data channel during a subsequent wake cycle. In some aspects, the UE may perform a measurement of one or more beams, of a set of beams, prior to the wake cycle. In some aspects, the UE may identify a beam, of the one or more beams, to use for communication with a base station (BS). In this way, the UE reduces a delay in data transfer associated with performing beam recovery after failing to decode the control channel or data channel during the wake cycle.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may report to a base station a beam switching capability of the UE. The beam switching capability may include a number of beam switches that the UE is capable of performing within a single transmission slot. In some cases, the beam switches may be performed by a UE by applying a particular spatial domain filter for uplink or downlink communications that is associated with a particular transmission and reception beam. In some cases, the base station may schedule transmissions or beam switches during a slot based on the UE capability. The number of beam switches, in some cases, may be determined based on a rule set that defines one or more actions that are to be considered to be a beam change.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficient identification of spatial parameters for receiving control information in an initial coreset. In one example, a user equipment (UE) may receive a transmission configuration indication (TCI) state indicating reference signals quasi co-located with a control information transmission in a coreset. The TCI state may be identified from a set of TCI states, where the set of TCI states includes at least one TCI state corresponding to each synchronization signal block (SSB) (e.g., each quasi co-location (QCL) source) associated with the initial coreset. The UE may identify spatial parameters for monitoring the coreset for the control information transmission in accordance with the TCI state.

Abstract: Aspects of the present disclosure provide for the transmission of group common control information in 5G New Radio (NR) wireless communication systems. Group common control information may be transmitted to a group or subset of user equipment (UEs) within a cell utilizing a beam-sweeping configuration. A base station may utilize a plurality of transmit beams to transmit information within the cell, and a subset of the transmit beams may be identified for use in transmitting the group common control information to the group of UEs. In addition, the base station may identify spatial quasi-colocation (QCL) relationships between reference beams corresponding in direction to the selected subset of transmit beams and resources reserved for the group common control information and provide the spatial QCL relationships to the UEs in the group.
