Classification: CPC H | IPC H

Claim 12:
13. A radio access node, the radio access node comprising processing circuitry and a non-transitory machine-readable medium storing instructions which, when executed by the processing circuitry, cause the radio access node to:
receive a buffer status report from a user equipment, the user equipment being configurable to communicate with the radio access node via a plurality of communication protocols, the one or more communication protocols comprising one or more of: a packet data convergence protocol (PDCP); a radio link control (RLC) protocol; or a media access control (MAC) protocol, and to communicate with a core network node via at least one congestion-controlled application transport protocol, the buffer status report comprising an indication of a first amount of data available for transmission from the user equipment, the first amount of data including data stored in a buffer for data conforming to the congestion-controlled application transport protocol, the congestion-controlled application transport protocol comprising one or more of: a transmission control protocol (TCP); a user datagram protocol (UDP); and a quick UDP internet connections (QUIC), and the buffer status report comprising respective separate indications for the amount of data stored in the application transport protocol buffer and an amount of data stored in one or more other buffers such that the buffer status report comprises one or more further indications of one or more respective amounts of data stored in the respective one or more other buffers, one or more other buffers comprising one or more of a PDCP buffer; an RLC protocol buffer; or a MAC protocol buffer;
prepare an uplink grant comprising an indication of radio resources to be used by the user equipment for transmitting a second amount of data in an uplink transmission, the second amount of data varying as a function of the first amount of data, preparing the uplink grant comprising giving higher priority to data conforming to one or more of the plurality of communication protocols than to data conforming to the congestion-controlled application transport protocol; and
transmit the uplink grant to the user equipment.
