Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

Abstract: A user equipment (UE) may transmit a power headroom report in response to changing beamforming parameters. The UE may autonomously change beamforming parameters from a preconfigured set of beams or receive a command to change beamforming parameters for transmissions on a new beam. The UE may determine a power headroom applicable to a transmission from the UE on the new beam. The UE may transmit, in response to the command, a power headroom report based on the power headroom using resources configured for the power headroom report. For example, the power headroom report may be multiplexed with an uplink transmission from the UE using the new beam. In an aspect, the UE may select a scheduled transmission during a time period after the command is implemented as the uplink transmission. For example, the power headroom report may be transmitted as a physical layer transmission or as a MAC-CE transmission.

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: In an aspect, a scheduled entity obtains a first set of indications associated with a beam failure recovery procedure, starts at least one of a first timer or a second timer based on the obtained first set of indications, and detects a radio link failure when the first timer expires or when the second timer expires. In some aspects, the scheduled entity starts at least one of the first timer or the second timer when N out-of-sync indications are obtained over a network configured time window, the N out-of-sync indications including aperiodic out-of-sync indications from the first set of indications and out-of-sync indications associated with a radio link monitoring procedure. In some aspects, the scheduled entity starts at least the second timer when the first set of indications includes a single aperiodic out-of-sync indication.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a mismatch between a user's common search space (CSS) and user-specific search space (USS). A base station (BS) may receive an indication that a user equipment (UE) decoded at least one beamformed signal transmitted by the BS in a USS and did not decode at least one beamformed signal transmitted by the BS in a CSS. The BS may take one or more actions based, at least in part, on the indication. Similarly, a UE may decode at least one beamformed signal transmitted by a BS in a USS, transmit to the BS an indication that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a CSS, and take one or more actions based, at least in part, on the indication.

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: 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.
