1. A baseband processor comprising processing circuitry, wherein the processing circuitry is configured to perform operations including:
configuring a protocol stack to handle a plurality of carriers, wherein the protocol stack includes a radio link control (RLC) entity, wherein one or more round trip time (RTT) status reporting control parameters of the RLC entity are configured separately for each of the carriers and at least one other RLC parameter is configured to be the same for all carriers, wherein a first status reporting control parameter of the one or more RTT status reporting control parameters represents an amount of time to count, starting from a time of last uplink feedback transmission, before allowing another uplink feedback transmission.
