Embodiment Construction

[0037] Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the various aspects may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing these aspects.

[0038] first reference figure 1 , shows a communication system 100 of a base station, which is depicted as an evolved base station node (eNB) 102 that communicates with a user equipment (UE) 106 via an over-the-air (OTA) link 104 . In an illustrative aspect, UE 106 constructs a packet data unit (PDU) from a radio link control (RLC) sublayer service data unit (SDU). In particular, the RLC SDU component 108 employs a deterministic RLC segmentation, re-segmentation, and padding method or sequence of operat...

Abstract

A transmission entity (e.g., user equipment (UE)) is expected to reduce the segmentation of Radio Link Control (RLC) Service Data Units (SDUs) while also minimizing padding. Signaling or provisioning of a constraint value such as a maximum padding amount or minimum segmentation size is employed in a determinative way in the UE to balance these objectives. A receiving entity (e.g., evolved base node (eNB)) benefits from being able to signal these parameters, whose application to RLC instances can discriminate between data and signaling radio bearers. Compliance can also be voluntary, such as the network entity employing at least a portion of the same approach on the downlink.

Description

[0001] Claiming priority under 35 U.S.C. § 119 [0002] This patent application claims "Mechanism and Apparatus for Minimizing Segmentation / Re-segmentation / Padding in LTE" filed on March 31, 2008. LTE), U.S. Provisional Application Serial No. 61 / 041,201, which is assigned to the assignee of the present application and is hereby incorporated by reference. technical field [0003] The exemplary and non-limiting aspects described herein relate generally to wireless communication systems, methods, computer program products, and devices, and more particularly, to methods for distributing radio link control (RLC) service data units (SDUs). Deterministic techniques for segmentation, resegmentation, and padding. Background technique [0004] Wireless communication systems are widely deployed to provide various communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing availab...
