Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, wireless devices (e.g., user equipment (UEs) and base stations) may communicate using beamformed transmissions. If a wireless device receives a transmission over multiple receive beams, the device may utilize signal measurements over the beams to determine a signal direction, a type of noise associated with the transmission, or both. The device may determine a signal direction based on received signal strength measurements over at least two receive beams and may select a beam for communication based on the determined signal direction. Additionally or alternatively, the device may compare noise measurements for the signal over at least two receive beams and may determine whether the noise corresponds to interference or white noise. The device may detect the direction of an interferer and may modify reception or demodulation based on the type of noise detected.

Abstract: Aspects are provided in which narrow channels are configured and carrier aggregated with defined channel bandwidths in order to support irregular channel bandwidths that are not a multiple of 5 MHz or other defined bandwidth multiple. An apparatus such as a UE receives, from a base station, a configuration for carrier aggregation for a PCell and one or more SCells. A total bandwidth of the PCell and the one or more SCells is not a defined bandwidth multiple. The apparatus communicates with the base station through the PCell and the one or more SCells. In this way, the available spectrum of wireless operators that include channel bandwidths of irregular size may be supported.

A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine an emissions mask (e.g., an in-band emission (IBE) mask) for a user equipment (UE) which may be determined based on the total number of UEs scheduled by the base station for uplink transmissions during a same transmission time interval (TTI). The base station may transmit downlink control information (DCI) to the UE indicating the emissions mask. The base station may additionally transmit a grant to the UE allocating resources for the UE based on the UE's position relative to other UEs served by the base station. The UE may receive the DCI and may map the emissions mask to a maximum power reduction (MPR). Based on the MPR, the UE may determine a transmit power and may transmit an uplink transmission to the base station according to the transmission power and the DCI.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.

A user equipment (UE) configured for CA determines to signal supported CA combinations that include a band, the band being one of a first band and a second band. The first band is a superset of the second band. The UE signals the supported CA combinations that include the band to the network. A base station receives a signal indicating the CA combinations supported by the UE that include the band. The base station determines CA combinations that include the first band and CA combinations that include the second band based on the CA combinations received from the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a measurement configuration on a first cell specifying a measurement gap for measuring cells on other frequencies. The UE may then measure a second cell and determine an offset between the timing of the two cells. If the measured frequency band is synchronized (or nearly synchronized), the length of the measurement gap may be reduced. In some cases, the UE may then make measurements on the second cell using a reduced measurement interval, and the UE may power down certain components during the rest of the measurement gap to conserve power. In other cases, the UE may coordinate with the serving cell to reduce the measurement gap to minimize the interruption caused by the gaps.

Abstract: Methods and apparatuses of wireless communications are provided to dynamically determine capability information such that potential configuration and/or resource conflicts may be mitigated among multiple connections while one or more of on-going connections are not interrupted. A user equipment (UE) establishes one or more connections with a network. The UE allocates, in a first resource allocation, one or more resources of the UE to the one or more connections. The UE dynamically determines an instantaneous UE capability information (IUCI) of the UE in response to a change from the first resource allocation to a second resource allocation, the IUCI indicative of the capability of the UE during a predetermined time period. The UE transmits the IUCI to the network to mitigate potential resource allocation conflict among the one or more connections while maintaining at least one of the connections.
