Embodiment Construction

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] Please refer to figure 1 , which is a protocol block diagram of an existing communication system. Such as figure 1 As shown, the layer 2 (L2) protocol stack defined in the 3GPP protocol includes packet data convergence protocol (PDCP), radio link control (radio link control, RLC) protocol and medium access control (medium access cont...

Abstract

An embodiment of the invention provides a data processing device and method. A plurality of RLC sub-units are configured for a logical channel, and then a plurality of independent RLC processing is performed on data on a same RB, thereby equaling that one RB is detached into a plurality of virtual RBs, so that processing of an L2 protocol upon the data is more flexible.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular, to a data processing device and method. Background technique [0002] The layer 2 (L2) protocol stack defined in the 3rd generation partnership project (3GPP) protocol includes packet data convergence protocol (PDCP), radio link control (radio link control, RLC) Protocol and media access control (medium access control, MAC) protocol three logical levels. Among them, both the PDCP layer and the RLC layer use radio bearers (radio bear, RB) as the minimum work object, and the MAC layer takes one or more RBs as the minimum work object. However, the current L2 protocol lacks flexibility. In the process of data processing, if the minimum work object RB needs to be further logically split, the current L2 protocol encounters difficulties. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a dat...
