Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.

Abstract: Wireless communications systems and methods related to handling link failures in a first cell and a second cell are provided. A wireless communication device can detect a first link failure associated with a first cell and can detect a second link failure associated with a second cell. Additionally, the wireless communication device can perform a link failure recovery procedure. This may include prioritizing a first link failure recovery for the first cell over a second link failure recovery for the second cell. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may identify that the UE is capable of performing up to a maximum quantity of antenna panel switches within a slot. For example, the UE may be capable of switching from operating one or more first antenna panels to operating one or more second antenna panels up to a maximum quantity of times within a slot. In some aspects, the UE may transmit an indication of the UE capability to a base station. The base station, based on receiving the indication of the UE capability, may transmit activation signaling indicating one or more antenna panel switches at the UE within a slot that is less than or equal to the maximum quantity of antenna panel switches per slot indicated by the UE capability.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station using a beamforming configuration, according to a transmission configuration indicator (TCI) configuration. The UE may receive a message including a TCI configuration. The UE may determine based on the TCI configuration, a TCI pool for a TCI state type of a set of TCI state types and a set of CCs. The UE may then perform the wireless communication via a directional beam based on the TCI pool for the TCI state type and the set of component carriers (CCs).

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration message indicating a first reporting quantity type and a second reporting quantity type for generating a measurement report. The UE may determine a measurement payload size to use for generating a measurement payload for the first reporting quantity type and the second reporting quantity type. The UE may measure a first set of resources in accordance with the first reporting quantity type and a second set of resources in accordance with the second reporting quantity type. The UE may transmit, to the base station, the measurement report including a first measurement payload having the measurement payload size for the first reporting quantity type and a second measurement payload having the measurement payload size for the second reporting quantity type.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message triggering the UE to perform an iterative joint beam pair selection procedure for selecting a receive beam and a transmission beam. In some cases, the UE may additionally receive control signaling from the base station configuring the UE to generate a measurement report associated with the receive beam (e.g., that is associated with a first and second port of the UE). The UE may then receive a reference signal via the receive beam. Based on receiving the reference signal, the UE may transmit the measurement report to the base station, where the measurement report indicates at least one measurement, a first resource index corresponding to the first port of the UE, and a second resource index corresponding to the second port of the UE.

Abstract: The present disclosure provides signaling for user equipment (UE) panel identification. The UE may have at least a first panel and a second panel. The UE may receive at least one downlink reference signal from a base station. The UE may determine a first mapping of the at least one downlink reference signal to one or more panel identifiers. The UE may receive a configuration of an uplink reference signal resource. Based on the configuration, the UE may transmit an uplink reference signal using a selected panel, the selected panel being associated with a selected panel identifier. The UE may transmit a report including a second mapping between the selected panel identifier and the uplink reference signal. The UE may receive an uplink grant indicating the selected panel associated with the selected panel identifier. The UE may transmit an uplink data channel using the selected panel.

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 communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.
