Abstract:
A CDMA telecommunication system comprising:a plurality of protocol layers including a physical layer and a medium access control (MAC) layer such that the MAC layer provides data to the physical layer via plurality of transport channels; each transport channel associated with a set of logical channels for transporting logical channel data within transport channel data; at least one transport channel associated with a set of logical channels having at least two logical channels which are different logical types; said physical layer receives blocks of data for transport such that each of the transport blocks of data includes of a MAC header and logical channel data for one of said transport channels whereby, for a given transport channel, the logical channel data is for a selected logical channel from the set of logical channels associated with the given transport channel; each transport block having one of a selected limited finite number of transport block (TB) bit sizes; the logical channel data for each transport block having a bit size evenly divisible by a selected integer N greater than three (3); the MAC header for each transport block having a bit size such that the MAC header bit size plus the logical channel data bit size equals one of said TB bit sizes; the MAC header bit size being fixed for transport blocks transporting data for the same transport channel and same selected logical channel, but may be different from the MAC header bit size for transport blocks transporting data for a different transport channel or a different selected logical channel; and for said at least one transport channel associated with a logical channel set having at least two (2) different types of logical channels, a fixed MAC header bit size associated with each logical channel within said set selected such that each fixed MAC header bit size equals M modulo N where M is an interger greater than 0 and less than N.
