Abstract: Aspects of the present disclosure provide techniques for the UE to minimize the need to expend resources in conducting signal measurements for SCell by limiting the number of beams that may be scanned and reported back to the network. For example, in instances when the UE has been configured with an active transmission configuration indicator (TCI) state by the network, the UE may be configured to communicate on a limited set of beams (e.g., one beam for transmission (Tx) and another for receiver (Rx)). As such, the UE, during the periodic measurements, may limit the signal measurements to a limited set of beams from all available beams in order to conserve resources based on a determination that the UE is configured with TCI state.

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.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may monitor for a beam scanning period indicator from a base station; configure an interval for beam scanning; and beam scan with a set of beams at the interval for beam scanning. In some aspects, a base station may configure an interval for beam scanning by a user equipment; selectively provide, to the user equipment, a beam scanning period indicator identifying the interval for beam scanning; and provide at least one beam from a set of beams in a synchronization codebook to enable the user equipment to perform beam scanning using the interval. Numerous other aspects are provided.

Abstract: Systems, methods, apparatuses, and computer-readable storage media for communicating a base station signal, such as a data signal, a control signal, or both, from a base station to a user equipment (UE) during a measurement window. In some aspects, the UE signals its availability corresponding to a measurement window to a serving base station. In some aspects, the UE signals a guard period associated with the measurement window to the serving base station. In other aspects, the serving base station signals a guard period to the UE.

Abstract: Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.

Another method includes receiving an indication of co-located downlink carriers in a shared radio frequency spectrum band; performing a plurality of RRM measurements for the downlink carriers; combining the RRM measurements over a time interval in the shared radio frequency spectrum band based at least in part on the received indication; and transmitting a report based at least in part on the combined RRM measurements to a base station.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques and devices for uplink gap configuration and determination of uplink resources after uplink gap distribution. Certain aspects are directed to an apparatus for wireless communications at a user equipment (UE). The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the instructions may cause the apparatus to obtain, from a base station, an uplink gap pattern (ULGP) configuration indicating a first ULGP associated with a first time window, wherein the first ULGP is indicative of a distribution of one or more uplink slots activated as uplink gaps within the first time window, and wherein the one or more uplink slots are independent from being used for any transmission initiated by the apparatus.
