Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first serving cell for a set of transmission time intervals (TTIs) including a first TTI and receive a second slot format configuration for the first serving cell for the first TTI which is different from the first slot format configuration. The UE may determine, based on priorities of the slot format configurations, a first communication direction for the first serving cell for the first TTI. The UE may identify, for a second serving cell for the first TTI, a second communication direction indicated by one or more slot format configurations for the second serving cell. The UE may determine whether to communicate on the second serving cell for the first TTI according to the one or more slot format configurations for the second serving cell.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating with a base station via beamformed transmissions on an active beam. The UE may receive from the base station refined reference signals (RRSs) that include an active beam RRS corresponding to the active beam. The UE may identify that the active beam RRS corresponds to the active beam and perform a beam state measurement on the active beam RRS. The UE may refine the active beam based at least in part on the beam state information of the active beam RRS.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

Abstract: In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in the unlicensed spectrum in order to save power and resources.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may reconfigure at least one antenna of the set of antennas to perform a first scan on the radio frequency spectrum band of a second RAT. The UE may determine, based on the first scan, whether to reconfigure a remaining portion of the antennas of the set of antennas to perform a second scan on the radio frequency spectrum band of the second RAT.

Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.
