Multiplexing channels by a medium access controller

A communication device comprising:

• at least one component device configured to implement a medium access control (MAC) function;
• wherein the MAC function receives data from a plurality of channels;
• wherein each channel is associated with a priority, where mandatory data is assigned a higher priority than best effort data, and is provided with a dynamically adjusted parameter which indicates a size limit of an amount of data for multiplexing for that channel to prevent monopolization of a shared channel by one of the plurality of channels;
• wherein the MAC function multiplexes the data of the plurality of channels for transmission over the shared channel based on the priority, wherein H-ARQ control information is multiplexed onto the shared channel and the H-ARQ control information is multiplexed regardless of the priority of the plurality of channels.

A communication device comprising:

• receiving data from a plurality of channels by a medium access controller (MAC) of the communication device;
• wherein each channel is associated with a priority, where mandatory data is assigned a higher priority than best effort data, and is provided with a dynamically adjusted parameter which indicates a size limit of an amount of data for multiplexing for that channel to prevent monopolization of a shared channel by one of the plurality of channels;
• and
• multiplexing the data of the plurality of channels by the MAC for transmission over the shared channel based on the priority, wherein H-ARQ control information is multiplexed onto the shared channel and the H-ARQ control information is multiplexed regardless of the priority of the plurality of channels.
