Abstract: A communication system that includes a plurality of radio points is disclosed. Each radio point is configured to exchange radio frequency (RF) signals with a wireless device that transmits a Sounding Reference Signal (SRS) from a first physical location in a site; and extract at least one SRS metric from the SRS. The communication system also includes a baseband controller communicatively coupled to the plurality of radio points. The baseband controller is configured to determine a signature vector based on the at least one SRS metric from each of the plurality of radio points. The communication system also includes a machine learning computing system communicatively coupled to the baseband controller. The machine learning computing system is configured to use a machine learning model to determine location data for the first physical location of the wireless device based on the signature vector.

Abstract: Systems and methods for preventing power imbalance across antennas for DMRS transmissions are provided herein. In one example, a method includes receiving an indication of a requested precoder from a user equipment, wherein the requested precoder is included in a codebook defined in a 3GPP specification. The method further includes applying a modified precoder corresponding to the requested precoder. The modified precoder is included in a modified codebook that is a modified version of the codebook defined in the 3GPP specification. The method further includes transmitting a double-symbol demodulation reference signal with the modified precoder to the user equipment.

Abstract: A system includes remote unit(s) (RU(s)). The RU(s) is/are configured to transmit at least one signal on a plurality of different beam patterns, each beam pattern comprising an active subset an inactive subset of a plurality of fine beams covering an area of a cell. The RU(s) is/are also configured to receive, from each of a plurality of user equipment (UEs) in the area, a respective signal strength measurement for each of the plurality of different beam patterns. The system also includes a centralized unit communicatively coupled to the plurality of RUs via a fronthaul interface. The centralized unit is configured to determine a bit vector for each UE based on a combination of the signal strength measurements from the respective UE. The centralized unit is configured also to select a respective fine beam for each UE based on the respective bit vector for the UE.

Abstract: A base station includes at least one remote unit (RU) that exchanges radio frequency (RF) signals with a user equipment (UE) using an air interface. The base station also includes a controller communicatively coupled to the at least one RU. The controller forms first RLC protocol data units (PDUs) for a first cell and second RLC PDUs for a second cell based on Radio Link Control (RLC) service data units (SDUs). A first at least one processor in the controller performs first Medium Access Control (MAC) scheduling for the first cell based on a first buffer occupancy update to produce a first scheduling decision. A second at least one processor in the controller performs second MAC scheduling for the second cell based on a second buffer occupancy update to produce a second scheduling decision.
