Embodiment Construction

[0090] figure 1 A smartphone 1 is shown communicating with a pair 7 of wireless earphones. Smartphone 1 and wireless earphone 7 respectively embody the invention.

[0091]The smartphone 1 has a memory 2 connected to a microprocessor 3, such as an ARM Cortex A series, possibly part of a larger system-on-chip, such as a Qualcomm Snapdragon. The microprocessor 3 is connected to a short-range radio transmitter module 4 . The short range radio transmitter 4 includes a data packet encoder 5 (among other functional elements). Other conventional components are also present, such as user interface, batteries, cellular network radio transceiver, etc., but are omitted from the drawings for clarity. The microprocessor 3 and the short range radio transmitter module 4 may be integrated on a single silicon chip, or may be separate components. The smartphone 1 has a radio antenna 6 which can be integrated with the short-range radio transmitter 4 or can be external to it. The memory 2 sto...

Abstract

A radio communication apparatus (1) receives or generates a base address seed, and generates data-channel access addresses from the seed. Each access address corresponds to a respective data-channel identifier, and is generated by setting a bit at a common first bit position to the value of a bit at a first common predetermined bit position in the base address seed or in the respective data-channel identifier; by setting a bit at a common second bit position to the bitwise complement of this value; and by setting one or more remaining bit positions in dependence on values at one or more bit positions in the base address seed and one or more bit positions in the respective data-channel identifier that are not the first common predetermined bit position. The apparatus (1) can send or receivea radio data packet comprising an access address from the generated set.

Description

technical field [0001] The present invention relates to radio communication devices and methods. Background technique [0002] In digital radio communication systems, it is often necessary to have multiple logical links or channels between two or more parties to share a limited bandwidth within one physical channel. Sometimes this is accomplished by tagging each packet with a tag that identifies a particular channel. Depending on the radio protocol or context, this label may be called an "Access Address", "Address", "Access Code", "Logical Link Identifier", "Sync Word", "Sync Signal", etc. The radio receiver may then choose to process data packets from one or more targeted logical channels, while discarding data packets from other logical channels within the same physical channel based on the channel labels contained in the data packets. The receiving device can configure the correlator to use the desired channel label as a correlation code to distinguish data packets belo...
