flexible first-layer configuration of radio interface for connecting radio to PLMN

Abstract

Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. Each transport channel can include an encoder or a decoder coupled to and cooperable with a data puncturer or a data repeater. An information source can produce for each transport channel first configuration information and second configuration information, wherein the first configuration information is indicative of how the associated transport channel is to be configured if a first modulation type is used for a current radio block, and wherein the second configuration information is indicative of how the associated transport channel is to be configured if a second modulation type is used for the current radio block. The physical layer can include a description information source that provides description information from which various configurations of the transport channels can be determined. The description information source provides the description information in the physical layer in response to further information which the description information source receives from a higher layer and which is indicative of a service request initiated by a communication network. One of the transport channels can be enabled to extract its associated communication information from a radio block while another of the transport channels is maintained disabled. The one transport channel provides the extracted communication information to a decision maker in a higher layer. In response to the extracted communication information, the decision maker decides whether the other transport channel should be enabled, and provides to the physical layer an indication of its decision.

Description

[0001] This patent application claims priority under 35 USC 119(e)(1) to co-pending US Provisional Patent Application No. 60 / 287,401, filed May 1, 2001, which is incorporated by reference. technical field [0002] The present invention relates generally to a radio interface connected to a PLMN, and more particularly to the first layer of the radio interface and its interaction with higher layers. Background technique [0003] FIG. 1 schematically shows a conventional example of a PLMN coupled to a mobile station (MS) 13 via a physical radio interface 17 . The PLMN comprises a radio access network 11 coupled to a core network 15 . The core network 15 may be a packet switched core network or a circuit switched core network. A mobile station 13 (mobile radio transceiver of any type) communicates via a radio interface 17 with a Base Transceiver Station (BTS) of the radio access network 11 . The physical layer of the mobile station, also referred...

Problems solved by technology

[0033] Thus, the conventional approach of using a predetermined and fixed layer-1 transport channel scheme disadvantageously implies a memory-intensive and complex implementation in the physical layer, as well as costly changes in order to be able to offer new services
