Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Techniques for managing base station beam panic for new radio technologies may include a user equipment (UE) measuring a signal quality of a serving beam from a base station. The UE may determine the signal quality has decreased by at least a threshold amount, and enable a signal panic operation to search for a beam different from the serving beam, in response to the signal quality decreasing by at least the threshold amount.

Abstract: Aspects of the disclosure relate to devices, systems and methods for multi-beam formation. A user equipment (UE) may determine a sampling interval for references signals to be transmitted by a base station for an upcoming control or data communication. For example, the UE may determine a maximum sampling interval tolerable for channel estimation and select the sampling interval based on the maximum. In some examples, the UE determines the sampling interval based on characteristics of its motion. The UE transmits an indication of the sampling interval to the base station. Based on the indication, the base station selects an interval for the reference signals and transmits the reference signals to the UE to enable it to perform the channel estimation for the multi-beam. The base station may determine to select the interval for the reference signals such that it is less than or equal to the sampling interval indicated by the UE.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling component carriers and one or more operations on a per NB RF chain basis. A method that may be performed by a user equipment (UE) includes monitoring occurrences of a first number of operations to be performed for a plurality of component carriers (CCs) according to different periodicities, determining a second number of available narrow band (NB) radio frequency (RF) chains, and scheduling, on the available NB RF chains, up to the second number of the operations to be performed for the plurality of CCs based on a scheduling algorithm if the first number is greater than the second number.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may communicate via a serving beam set of the UE, the serving beam set being one or more of a plurality of beams. The UE may measure another beam set in accordance with a measurement schedule configured to prioritize measurement on one or more adjacent beam sets associated with the serving beam set over one or more non-adjacent beam sets associated with the serving beam set. In some aspects, the one or more adjacent beam sets may be associated with one or more coverage areas that at least partially overlap a coverage area of the serving beam set, are adjacent to the coverage area of the serving beam set, or are associated with a measurement value that satisfies a threshold in the coverage area of the serving beam set. Numerous other aspects are provided.
