Patent ID: 8542688

Claim:
A data link layer protocol unit, in a mobile radio device, configured to map useful data and a plurality of Radio Link Layer (RLC) buffer store filling levels, based on a plurality of respective prioritization information items, from at least one logical channel onto at least one transport channel, wherein the useful data and the plurality of RLC buffer store filling levels are to be transmitted from the mobile radio device to at least one base station of a cellular radio network via the at least one transport channel, the data link layer protocol unit further comprising: a plurality of data link layer protocol buffer stores configured to buffer-store the useful data which are to be transmitted from one or more data link layer data streams for the useful data of the logical channel, and the plurality of RLC buffer store filling levels of the at least one logical channel; a data link layer protocol buffer store association unit configured to associate the plurality of RLC buffer store filling levels of the at least one logical channel with the data link layer protocol buffer store associated with the respective prioritization information item based on the plurality of prioritization information items; and a data link protocol buffer store reading device configured to read the data buffer-stored in the data link layer protocol buffer stores based on a prescribable criterion taking into account the prioritization of the data link layer protocol buffer stores.
