Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures a measurement gap for the UE. The UE may perform a first measurement and a second measurement in the measurement gap, wherein the first measurement and the second measurement are different types of measurements. The UE may transmit measurement information based at least in part on the first measurement or the second measurement. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration for at least a first transmission-reception point (TRP), the PRS configuration including one or more repetitions of one or more PRS resources within a PRS resource set of a PRS instance associated with the TRP, beam sweeps one or more receive beams within the PRS instance based on a number of the one or more repetitions being greater than a number of repetitions of the one or more PRS resources needed to meet an accuracy requirement, and beam sweeps the one or more receive beams across a plurality of PRS instances associated with the TRP based on the number of the one or more repetitions not being greater than the number of repetitions of the one or more PRS resources needed to meet the accuracy requirement.

Abstract: In an aspect, a UE receives, from a network entity, a configuration of PRS or SRS-P resources for a positioning session, receives a configuration of at least one BWP from a serving BS, identifies a time-domain period for the positioning session where a set of parameters associated with the at least one BWP is to remain constant to achieve a first positioning accuracy requirement. The UE either performs positioning measurements on one or more of the PRS resources during the positioning session or transmits on one or more of the SRS-P resources during the positioning session. The UE determines an active BWP transition during the time-domain period from a first BWP to a second BWP that is associated with one or more changes to the set of parameters.

Abstract: A UE transmits to a source base station a capability of the UE associated with a bandwidth class or a band combination. The capability is associated with a handover in which the UE maintains connections with the source base station and a target base station. The UE receives a handover message comprising at least one of a target base station configuration to apply during handover execution or a source base station configuration to apply during handover execution based on the capability of the UE. The UE establishes a connection with the target base station and maintains a connection with the source base station over a period of time during the handover. The UE communicates with the source base station and the target base station during handover execution using at least one of the target base station configuration or the source base station configuration.

Various aspects may include determining measurements of communication performance of the wireless device at each of a number of different angular orientations of the wireless device with respect to an antenna within a test chamber, and determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to pass/fail criteria. Further embodiments may include a wireless device testing apparatus configured to perform testing wireless devices for beam forming performance. In some embodiments, a wireless device testing apparatus may include a test chamber, an antenna within the test chamber, a rotatable positioning system within the test chamber configured to hold a wireless device and rotate the wireless device within a range of orientations with respect to the antenna, and a computing device coupled to the antenna and the rotatable positioning system.
