Abstract:
1. In a mobile telecommunications system, a method of indicating length of a data payload to be transported in a packet, the method comprising: a. assessing the length of a data section to determine appropriate units, from a plurality of possible units, in which the length should be expressed; b. setting a granularity field to define said appropriate units in which the length of the data section is to be indicated in a data length indicator field; and c. setting the length indicator field to indicate the data length; wherein the packet is assessed to determine whether it contains more than one payload unit, and each payload unit is assessed to determine said appropriate units; wherein the granularity field is set according to the units of the payload unit which is to be expressed in the smallest units, unless the payload units can be expressed in larger units of the possible units whereupon the granularity field is set according to such larger units.
