1. A baseband processor comprising processing circuitry, wherein the processing circuitry is configured to perform operations including:
configuring a protocol stack to use a plurality of carriers, wherein the protocol stack includes a first radio link control (RLC) entity and a second RLC entity, both interfaced with a packet data convergence protocol (PDCP) entity, wherein the carriers include one or more first carriers whose respective carrier frequencies are below a frequency threshold, and one or more second carriers whose respective carrier frequencies are greater than or equal to the frequency threshold, wherein said configuring includes configuring the first carriers differently from the second carriers including:
configuring the first RLC entity to handle the first carriers, wherein the first RLC entity is configured to use a first value of a status reporting control parameter for the first carriers; and
configuring the second RLC entity to handle the second carriers, wherein the second RLC entity is configured to use a second value of the status reporting control parameter, wherein the second value is configured for the second carriers separately from the first value and is configured to be smaller than the first value, wherein the status reporting control parameter represents an amount of time to count, starting from a time of last uplink feedback transmission, before allowing another uplink feedback transmission.
