Apparatus and method to request a data rate increase.

Abstract

A method includes, in response to selection of a transport block to be transmitted through a wireless channel at a current data rate, performing at least the following: selecting a size -for a data unit that can be scheduled for transmission; identifying one of a number of potential transport blocks, the identified potential transport block having a corresponding transport block size large enough to hold at least the selected size of the data unit and the transport block size of the currently selected transport block; determining whether the identified potential transport block is available for transmission, and transmitting a request for an increase in the current data rate in response to the identified potential transport block being available for transmission.
