Embodiment Construction

[0018] In the following description, for purposes of explanation rather than limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc., in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. For example, although the invention has been described with an example application to the UMTS / UTRAN system, the invention may be employed in any cellular radio system providing multimedia services.

[0019] In certain instances, detailed descriptions of well-known methods, interfaces, devices, and signaling techniques are omitted so as not to obscure the description of the present invention with unnecessary detail. Also, in some of the figures, individual functional blocks are shown. Those skilled in the art will appreciate that the functions may be implemented usin...

Abstract

The present invention solves these problems by providing the possibility to configure or reconfigure a rate matching attribute for a given transport channel without having to perform unnecessary transport format configurations / reconfigurations. A connection with a mobile radio is established using a configuration of a radio channel that specifies a first transport format. When some aspect of the connection is to be changed, the radio channel configuration will be reconfigured, but not entirely or unnecessarily. The reconfiguration may result from a new service being added to the connection, aservice for the connection being removed, or some aspect of the radio channel configuration being modified, e.g., rate change, etc. As a result of the reconfiguration, one or more rate matching parameters associated with the connection are configured without having to configure the first transport format. A rate matching algorithm is used to control an amount of data sent over the reconfigured radio channel per unit time based on one or more reconfigured rate matching parameters and one or more transport formats.

Description

technical field [0001] The present invention relates to signaling in mobile radio communication networks, and more particularly to signaling related to physical layer configuration changes. Background technique [0002] Mobile radio communication systems have been developed through three generations, including analog (first generation), digital (second generation), and multimedia (third generation). Third generation systems are sometimes associated with the Universal Mobile Telecommunications System (UMTS). An example of a UMTS radio access network is the UMTS Terrestrial Radio Access Network (UTRAN) specified in a joint standardization project denoted 3GPP (Third Generation Partnership Project). In UTRAN, data generated in higher layers is carried over a radio interface with transport channels. These transport channels are mapped to different physical channels in the physical layer. The physical layer is required to support variable bit rate transport channels to provide...
