AI Technical Summary

Problems solved by technology

The first problem is that there may not be enough TFCI words (64 or 1024)
The second problem is that the performance of TFCI detection depends on how many TFCI codewords are being used
Therefore, the allocation used in the TS 25.212 specification suffers from wasting this TFCI codeword

Embodiment Construction

[0022] In the following description, for purposes of explanation rather than limitation, specific details are set forth such as specific architectures, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to those skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0023] According to the invention, different transport format combinations (TFCs) are assigned to a different transport format combination indicator (TFCI) in an efficient manner, so that only the combination actually used is signaled. In particular, according to the present invention, higher layers signal the used TFCIs to the first layer, so that each allowed TFC can be unambiguous...

Abstract

The Calculated Transport Format Combination (CTFC) provides efficient signaling of the Transport Format Combination for which the TFCI value is to be assigned. The CTFC sequence is signaled from higher layers (30) to the Node B (22) and User Equipment (UE) (20), with each CTFC in turn being assigned a TFCI value. The exact transport format combination represented by the TFCI value (used for communication between the Node B and the UE) can be determined by the CTFC Node B and User Equipment (UE). The sequence of CTFC values ​​includes only CTFC values ​​for valid transport format combinations.

Description

[0001] This application claims priority and the benefit of US Provisional Patent Application Serial No. 60 / 151,047, filed August 27, 1999, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to telecommunications, and in particular to telecommunications operations in which a plurality of transport channels, each with potentially multiple transport formats, are multiplexed for transmission. Background technique [0003] In a typical cellular radio system, mobile user equipment units (UE) communicate with one or more core networks via a radio access network (RAN). User Equipment Units (UE) may be mobile stations, such as mobile telephones ("cellular" telephones) and laptops with mobile terminals, and thus may be, for example, portable, pocket, handheld, contained in a computer, or vehicle Mobile devices installed on the network, these devices communicate with the wireles...
