Embodiment Construction

[0022] figure 1 is a schematic block diagram of an apparatus 1 for transmitting and receiving signals in a wireless communication system. Such a device can be implemented in many different ways, but in figure 1 In the example shown, a transceiver implemented in the form of an analog interface 12 comprising radio frequency (RF, radio frequency) and intermediate frequency (IF, intermediate frequency) stages is arranged to receive and transmit wireless signals via one or more antennas 14 ( Rx and Tx). The analog interface 12 comprises components for processing received analog radio signals Rx and components for providing digital signal samples r(k). This can be achieved in different ways known in the art.

[0023] The analog interface 12 is arranged to provide the samples r(k) to a data transfer engine 10 arranged in communication with the processor 2 , the instruction memory 4 and the data memory 6 . Processor 2 is responsible for processing samples r(k). The processor can ...

Abstract

An inter-radio-access-tech noiogy device comprising: an interface for communicating over a wireless cellular network, and a processor arranged to execute code for performing operations handling communications via the interface according to a plurality of different radio access technologies. The processor is operable to execute code using any selected one of a plurality of different instruction sets, each set being configured for performing operations according to a respective one of the radio access technologies. The device is operable to dynamically switch between the radio access technologies, by selecting corresponding code for execution by the processor and selecting the corresponding instruction set for use in execution of the selected code.

Description

technical field [0001] The present invention relates to a set of instructions for performing operations for handling communications over a wireless cellular network. Background technique [0002] In the field of wireless cellular communications, there has been increasing interest in recent years in the idea of ​​moving more of the transceiver's signal processing operations and other related operations into software. Transceivers that tend to favor a software implementation are sometimes referred to as software modems, or "soft modems." The principle of a software modem is to perform a substantial portion of the operations required for wireless communication in a general-purpose, programmable, reconfigurable processor rather than in dedicated hardware. [0003] An advantage of a soft modem type system is that it can be programmed and possibly reprogrammed to handle different radio access technologies (RATs). Traditionally, different radio access technologies may require dif...
