Embodiment Construction

[0038] 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.

[0039] first reference figure 1 , shows a communication system 100 of a base station, wherein the base station 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 packet data units (PDUs) from radio link control (RLC) sublayer service data units (SDUs). In particular, the RLC SDU component 108 employs a deterministic RLC segmentation, re-segmentation, and padding method or...

Abstract

The sending entity (eg, user equipment (UE)) is expected to reduce the fragmentation of radio link control (RLC) service data units (SDUs) while minimizing padding. Signaling or specification of constraint values ​​(eg, maximum padding or minimum segment size) is used in the UE in a deterministic manner to balance these goals. Applying these parameters to an RLC instance can be useful for both data radio bearers and signaling radio bearers by enabling the receiving entity (eg, an evolved base station node (eNB)) to signal these parameters to the benefit of the receiving entity. different. It is also possible to automatically conform, eg to network entities using at least part of the same method on the downlink.
