Embodiment Construction

[0028]The following is a description of example embodiments which, when described in conjunction with the accompanying drawings, illustrate the above-mentioned features and advantages, and introduce further features and advantages.

[0029] In the following description, for purposes of illustration and not limitation, specific details (eg, architectures, interfaces, techniques, devices, etc.) are set forth for illustration. However, it will be apparent to those skilled in the art that other implementations than these details will still be understood to be within the scope of the appended claims.

[0030] Moreover, for the sake of clarity, detailed descriptions of well-known devices, systems and methods are omitted so as not to obscure the description of the present system. Furthermore, routers, servers, nodes, gateways, or other entities in the telecommunications network are not described in detail, as their specific implementation is outside the scope of the present systems a...

Abstract

A method of allocating carriers from a list of carriers in a telecommunication network, each of said carriers allowing the transmission of a transmission control frame, each of said transmission control frame comprising a data block corresponding to a data stream and an indication of the previous carrier allocated to the data stream, said method comprising, for a transmission control frame and a carrier selected for allocation to said transmission control frame in said list of carriers, the acts of determining the number of binary bits needed to identify the number of carriers in the list of carriers, coding the indication based on the determined number of binary bits, removing the allocated carrier from the list of carriers.

Description

technical field [0001] The present invention relates generally to telecommunications network functions, and more particularly to telecommunications carrier identification. Background technique [0002] On the one hand, 3GPP LTE (Long Term Evolution, Long Term Evolution) is the name of the project in the 3rd Generation Partnership Project (3GPP) to improve the UMTS mobile phone standard for future needs. To date, goals have included increasing efficiency, reducing costs, improving services, taking advantage of new spectrum resources, and better integrating open standards. On the other hand, Advanced International Mobile Telecommunications (IMT) is dedicated to providing enhanced peak data rates to support advanced services and applications (100Mbit / s (megabit / second) for high mobility and 1Gbit / s ( Gigabit / s) was identified as a target for R&D). In conclusion, future 3GPP LTE-Advanced systems will require wider system bandwidths, eg, up to 100MHz, to achieve such high targe...
