Abstract
Official abstract text for this publication.
A device ( 110 ) receives a radio link control (RLC) protocol data unit (PDU) ( 740 ) or service data unit (SDU) ( 760 ) to be segmented, defines a padding threshold ( 840 ) for a segmentation mechanism, and determines a padding ratio ( 850 ) after enhanced dedicated channel transport format combination (ETFC) selection ( 730 ). The device selects a first transport block ( 960 ) and a second transport block ( 970 ) associated with the RLC PDU/SDU ( 740/760 ) when the padding ratio ( 850 ) is greater than or equal to the padding threshold ( 840 ), and generates a modified segmentation of the RLC PDU/SDU ( 740/760 ) based on the first and second transport blocks ( 960/970 ) when a padding ratio (RTB) associated with the first and second transport blocks ( 960/970 ) is less than the padding threshold ( 840 ) and a size ratio (STB) associated with the first and second transport blocks ( 960/970 ) is within a size threshold ( 980 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A device comprising a processor and a memory, said memory containing instructions executable by said processor whereby said device is operative to implement a segmentation generator configured to receive a radio link control (RLC) protocol data unit (PDU) or service data unit (SDU) and to segment that RLC PDU or SDU for transmission in consecutive transmission time intervals (TTIs), the segmentation generator comprising: a padding threshold definer configure…
