AI Technical Summary

Problems solved by technology

Although the remainder of an RLC PDU or RLC SDU can wait in a buffer and be spliced ​​with a subsequently incoming SDU, this configuration is not always acceptable for delay sensitive services such as Voice over Internet Protocol (VoIP), etc.
Due to limited uplink

Embodiment Construction

[0025] The following detailed description refers to the accompanying drawings. In different drawings, the same reference numbers may identify the same or similar elements. Also, the following detailed description does not limit the invention.

[0026] Embodiments described herein may apply a modified MAC segmentation mechanism and / or a modified radio-aware RLC segmentation mechanism to minimize padding of RLC PDUs or SDUs during ETFC selection. The modified fragmentation mechanism described herein may ensure that less padding is included in the transport block size, which may prevent and / or reduce power waste, interference generation, and / or power hopping.

[0027] figure 1 A diagram of an example network 100 in which the systems and / or methods described herein may be implemented is depicted. As shown, network 100 may include a set of user equipments (UEs) 110-1 through 110-L (collectively and in some cases individually "user equipments 110"), a radio access network (R

Abstract

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).
