System and method for data size adaptation in a UE

摘要

A method is described for adapting the size of data for a future Transmission Time Interval (TTI) by a User Equipment (UE), wherein all the Media Access Control (MAC)-d flows are grouped and stored in different lists based on a type of grants associated with the MAC-d flows, ability of a MAC-d flow to be multiplexed with another MAC-d flow from a list, and data availability in a logical channel mapped onto a MAC-d flow in the current TTI. The E-TFC is then selected by the UE for the future TTI using the MAC-d flow having the highest power offset in a consolidated list including the grouped MAC-d flows. The size of the data is thereby adapted using the selected E-TFC. Further disclosed is a method for generating RLC PDUs by the UE for the future TTI using the variation in the scheduled grant for the UE and the size of the data adapted for the future TTI.

1. A method for generating Radio Link Control (RLC) Packet Data Units (PDUs) for a future Transmission Time Interval (TTI) by a User Equipment (UE), comprising the steps of:
adapting a size of the RLC PDUs for the future TTI, wherein the UE is in a current TTI; detecting a value for maximum variation in a scheduled grant for the UE; determining a factor using the detected value for the maximum variation; determining a maximum value of number of bytes using the factor and the size of the RLC PDUs adapted for the future TTI; and generating the RLC PDUs for the future TTI using the maximum value.
