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.

Each bit position is associated with a respective one of the RUs. Each RU is configured to: use the respective RU mask field included in any user-plane messages received by that RU in order to determine if the received user-plane message is intended for that RU and use the received message if the received message is intended for that RU and discard the received message if the received message is not intended for that RU.

Abstract: The present disclosure describes techniques of user equipment localization in centralized or cloud radio access networks (C-RANs). In the UE localization techniques of the present disclosure, a base station (gNB) configures a plurality of radio units (RUs) serving a cell to transmit one or more downlink signals using various time and/or frequency resources to user equipment (UEs) of the cell. The UEs use the one or more downlink signals to measure quality of downlink channels between the UEs and the plurality of RUs and reports the measured qualities in uplink using one or more CSI reports. The gNB then selects one or more RUs from the plurality of RUs for each UE based on the received CSI reports. Finally, the gNB transmits downlink data towards the UEs and receives uplink data from the UEs using their respective RUs.

Abstract: A distributed radio access network (RAN) includes a plurality of radio points (RPs), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE). The distributed RAN also includes a baseband controller communicatively coupled to the plurality of RPs via a fronthaul network. The baseband controller is configured to determine, for each of the plurality of RPs, a number of successfully received packets on the fronthaul network, for a wireless channel, during a measurement interval. The baseband controller is also configured to determine, for each of the plurality of RPs, a number of packet losses (reflecting dropped and/or delayed packets), for the wireless channel and during the measurement interval, based on the number of successfully received packets.
