Abstract:
1. In a mobile telecommunications system, a method of generating a data unit, wherein the data unit is employed, at least in part, to provide information to a serving base station about the amount of data that is available for transmission in an uplink, the method comprising: determining whether padding bits are available in the data unit; and if there are padding bits available in the data unit, inserting, into the data unit, a long buffer status report (BSR) and a sub-header corresponding to the long BSR if it is determined that the number of padding bits is greater than or equal to the size of the long BSR plus the sub-header corresponding to the long BSR; inserting, into the data unit, a short BSR and a sub-header corresponding to the short BSR if it is determined that the number of padding bits is greater than or equal to the size of the short BSR plus the sub-header corresponding to the short BSR, but less than the size of the long BSR plus the sub-header corresponding to the long BSR, and it is determined that only one logical channel group has buffered data available to transmit via the uplink; and inserting into the data unit a truncated BSR and a sub-header corresponding to the truncated BSR if it is determined that the number of padding bits is greater than or equal to the size of the short BSR plus the sub-header corresponding to the short BSR, but less than the size of the long BSR plus the sub-header corresponding to the long BSR, and it is determined that a plurality of logical channel groups have buffered data available to transmit via the uplink.
