Abstract: A repeater relays communications between UEs and a first BS. The repeater measures a time difference between signals received from the first BS and from a second BS. The repeater performs cell measurements of these signals. The repeater sends, to the first BS, information indicative of the measured time difference and of the cell measurements. The first BS communicates with the UEs through the repeater. The first BS receives, from the repeater, information indicative of a time difference between signals received from the first BS and signals received from a second BS as measured by the repeater, and of cell measurements by the repeater of these signals. The first BS makes a handover decision for the UEs based at least on the received information indicative of the cell measurements.

Abstract: A method for optimizing uplink performance of Open Radio Access Network (O-RAN) system implementing O-RAN split option 7-2x-based uplink (UL) multiple-input multiple-output (MIMO) operation includes: selectively utilizing non-port reduced DMRS symbols and non-port reduced DMRS measurements to mitigate performance degradation of the UL MIMO in conditions involving high mobility for a user equipment (UE) and/or high interference.

The DU transmits combining and/or digital beamforming matrix elements to the RU for combining and/or digital beamforming matrix application.
