Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a first sub-band and a second sub-band of a system bandwidth for communication with a user equipment (UE). The base station may determine a spatial quasi co-location (QCL) relationship between the first sub-band and the second sub-band and may transmit signaling to the UE that indicates the determined spatial QCL relationship. Upon receiving the signaling, the UE may derive, based on the indicated spatial QCL relationship, spatial parameters (e.g., beam width, pointing angle, etc.) for communication with the base station via the second sub-band. The spatial parameters may be derived based on spatial parameters used for reception of a downlink transmission from the base station via the first sub-band. Subsequently, the UE may communicate with the base station via the second sub-band using the derived spatial parameters.

Abstract: Methods, systems, and devices for wireless communications provide for transmission of a beam switch command to a user equipment (UE) via control channel signaling. The UE may establish a connection with a base station using a first transmission beam, receive configuration information configuring the UE to select between a first decoding hypothesis corresponding to downlink control information (DCI) including a bit field including a beam switch command and a second decoding hypothesis corresponding to the DCI not including the bit field, receive a downlink control channel transmission via the first transmission beam, decode the downlink control channel transmission in accordance with the configuration information to obtain decoded DCI, and communicate with the base station based at least in part on the decoded DCI.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques provide for configuration and transmission of reference signals over aggregated mini-slots by modifying (e.g., extending) transmission time intervals (TTIs) or sharing reference signals across multiple mini-slots. The reference signals may be shared between multiple aggregated mini-slots and a reference signal pattern may be determined based on data payload allocation, modulation coding scheme (MCS), rank, or other factors of the aggregated mini-slots. Data payloads may be scheduled jointly or separately for each mini-slot and may be allocated across a set of aggregated mini-slots.

Abstract: Methods, systems, and devices for wireless communication are described that support overriding a beam monitoring pattern for control channel transmissions based on channel conditions between a user equipment and a base station. A base station may select a beam monitoring pattern for transmitting control channel transmissions, which may include a pattern in which two or more beams are used for control channel transmissions. In the event that a first beam of the beams used in the beam monitoring pattern meets certain metrics, the use of one or more additional beams according to the beam monitoring pattern may be overridden and transmissions continued using the first beam. The metrics for continuing use of the first beam may include channel quality metrics, a number of consecutive successful transmissions using the first beam, one or more other metrics, or any combination thereof.

Abstract: Various aspects of the disclosure relate to managing the transmission of uplink beams. For example, a first apparatus may generate a signal for transmission to a second apparatus. Thereafter, the first apparatus may detect a condition associated with transmitting the signal via a first uplink beam at a first transmission power. The condition may include the first uplink beam exceeding a maximum permissible exposure (MPE) limit. Accordingly, the first apparatus may refrain from transmitting the signal via the first uplink beam based on the at least one condition and transmit the signal to the second apparatus using a second uplink beam different from the first uplink beam.

Abstract: Various aspects of the disclosure relate to controlling reporting operations based on the timing of certain reporting events. In some aspects, the manner in which an apparatus performs reporting operations may depend on how far apart in time two reporting events occur. As one example, if the timing of an event-triggered report closely follows the timing of a request-triggered report, the apparatus may skip or otherwise alter the event-triggered reporting.

Abstract: Methods, systems, and devices for wireless communication are described. Uplink resources may be allocated for transmissions of beam recovery messages. For example, a user equipment (UE) communicating in a system that supports beamformed transmissions may receive a configuration for resources from a base station, where the resources may be used for beam recovery signaling. The UE may identify a beam failure on one or more active beams used to communicate with the base station, and the UE may transmit a beam recovery message to the base station. In such cases, the beam recovery message may be transmitted according to the configuration received from the base station such that the beam recovery message is transmitted using the beam recovery resources. In some cases, the configuration may be received at the UE via radio resource control (RRC) signaling or via a system information broadcast from the base station.

Abstract: A grant may allocate resources for an uplink transmission by a user equipment (UE) in a system using beamforming, where the resources may be used by the UE to transmit data or control information during a time that a base station is listening in a certain receive beam direction. A UE may be in communication with a base station using beamformed transmissions, and the base station may send a resource grant to the UE for uplink transmissions that correspond to a receive beam direction of a beamsweeping operation. The UE may then transmit data and/or uplink control information to the base station according to the resource grant and when the base station is listening in the corresponding direction. In some examples, the UE may send the uplink transmission to the serving base station, and transmit a random access channel to another base station based on the beamsweeping operation.

Abstract: Wireless communications systems and methods related to transmitting uplink control information. A first wireless communication device receives a transmission configuration indicating first beam information and second beam information. The first beam information and the second beam information are different. The first wireless communication device transmits a first uplink control signal based on the first beam information. The first wireless communication device transmits a second uplink control signal based on the second beam information. The first uplink control signal and the second uplink control signal represent the same control information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may report a phase-noise compensation reference signal (PCRS) configuration to a base station to enable per-UE PCRS signaling. For example, a UE may operate in a wireless communications system using carrier frequencies greater than 6 GHz, which may be affected by phase noise. The UE may accordingly determine a PCRS configuration based on a capability to receive signals. The PCRS configuration may include a resource mapping for one or more PCRS, a number of PCRS ports used for PCRS, a multiplexing scheme for one or more PCRS ports, or the UE's phase noise estimation capability. The UE may then transmit a reporting message including the PCRS configuration to a base station. The base station may use the PCRS configuration for PCRS transmissions to the UE.
