Data link layer protocol unit, mobile radio device and method for mapping data which are to be transmitted using a mobile radio device from at least one logical channel, and control data which are to be transmitted, onto at least one transport channel

A data link layer protocol unit, in a mobile radio device,

• configured to map useful data and a plurality of Radio Link Control (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 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:
• at least one transport format memory configured to store a plurality of transport formats, where each transport format contains control parameters based on which the data are mapped from the at least one logical channel onto the at least one transport channel by the data link layer protocol unit, with the control parameters in at least some of the transport formats containing information regarding that or those data link layer protocol buffer stores and/or that or those data link layer data streams from which the data to be transmitted are to be transmitted in a data transmission time interval;
• at least one transport format selection unit configured to select a respective transport format which is to be used from the plurality of stored transport formats;
• and
• a data link layer protocol buffer store reading device configured to read the data buffer-stored in the data link layer protocol buffer stores based on the selected transport format.

A mobile radio device comprising:

• a data link layer protocol means for mapping useful data and a plurality of Radio Link Control (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;
• a plurality of data link layer protocol buffer means for buffer-storing 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 means for associating the plurality of RLC buffer store filling levels of the at least one logical channel with the data link layer protocol buffer means associated with the respective prioritization information item based on the plurality of prioritization information items;
• and
• a data link protocol buffer store reading means for reading the data buffer-stored in the data link layer protocol buffer means based on a prescribable criterion taking into account the prioritization of the data link layer protocol buffer means.
