Communication with compressed headers

A method that is performed by a receiving device to decode a header having a reduced size, the method comprising the steps of:

• receiving a mapping;
• receiving from a transmitting device a communication including a compressed header;
• extracting from the compressed header a compressed logical channel identifier;
• and,
• recovering a logical channel identifier from the compressed logical channel identifier;
• and,
• using the mapping, the logical channel identifier occupying more bits than the compressed logical channel identifier, where the logical channel identifier is based on a total number of available medium access control (MAC) services and the compressed logical channel identifier is based on a reduced number of the total available MAC services, where the reduced number of the total available MAC services are offered for compressed headers and assigned to a predetermined number of compressed logical channel identifiers, and where a maximum allowable value for the predetermined number is based on a number of bits in a compressed channel information field.
