Abstract: This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a packet data convergence protocol (PDCP) entity of a receiver device receives, from a radio link control (RLC) entity of the receiver device, a plurality of RLC data packets received from a transmitter device over an RLC unacknowledged mode (UM) data radio bearer (DRB) or RLC transparent mode (TM) DRB. The PDCP entity generates a plurality of PDCP data packets corresponding to the plurality of RLC data packets. The receiver device determines to send a PDCP status report indicating a reception status at the receiver device of the plurality of PDCP data packets and transmits the PDCP status report to a PDCP entity of the transmitter device. The receiver device receives, in response to sending the PDCP status report, one or more PDCP data packets of the plurality of PDCP data packets that were not successfully received at the receiver device.
