Abstract: Test entity for verifying user equipment (UE) device layer 2 sustained downlink maximum data rate decoding performance may send a non-access stratum message to the UE device that requests activation of a downlink-only test mode, sending a first Packet Data Convergence Protocol (PDCP) status request to the UE device, send downlink PDCP packets to the UE device during a measurement interval, receive a physical layer (PHY) hybrid acknowledge request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) from the UE device and determine expected missed layer 1 packets based on the received PHY HARQ ACK/NACK, send a second PDCP status request to the UE device after the measurement interval, receive a PDCP status report from the UE device, and determine missed layer 2 packets from a First Missing Count (FMC) value or bitmap included in the received PDCP status report.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam refinement procedures for a first set of beams and a second set of beams. The first set of beams corresponds to a first set of synchronization signal blocks (SSBs) of a serving cell and the second set of beams corresponds to a second set of SSBs of the serving cell. The UE may transmit a message indicating channel state feedback (CSF) including either a first power metric for the first set of SSBs or both the first power metric and a second power metric for the second set of SSBs. The power metric(s) included in the CSF may be based on a first refinement status for the first set of SSBs as well as a second refinement status for the second set of SSBs or the second power metric satisfying a threshold.

Abstract: Embodiments include methods of testing wireless devices for beam forming performance. 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.
