Abstract

The present disclosure relates to the concurrent operation of at least two wireless link paths. At least one first link path has a first digital transmission method and at least one second link path has a second digital transmission method. The carrier frequencies of these transmission methods lie in frequency bands that at least overlap. The transmission methods transmit, in defined frame and slot cycles, data in a sequence of frames subdivided into a plurality of slots. The frame and/or slot cycles of the transmission methods have different durations. The first transmission method is isochronous. The signal fields of the link paths overlap in such a manner that at the site of at least one receiver of a link path signals originating from two different transmission methods can be received. The slot events of the second transmission method are dynamically distributed to the slots available in the second transmission method depending on slot events of the first transmission method. The disclosure also relates to a transmitter which comprises a slot allocation device and to a receiver which comprises a slot evaluation device.

Claims

1-14. -14. (canceled)

15. A method for simultaneously operating at least two wireless link paths, having respectively different first and second transmission protocols, wherein at least some of carrier frequencies of the at least two wireless link paths overlap, the method comprising the steps of:

receiving a first transmission from a first of the at least two wireless link paths, said first transmission comprising first data in a sequence of frames subdivided into a plurality of slots, wherein the first data has defined frame and slot cycles, and wherein the first transmission protocol is isochronous;

receiving a second transmission from a second of the at least two wireless link paths simultaneously with the first transmission, said second transmission comprising second data in a sequence of frames subdivided into a plurality of slots, wherein the second data has defined frame and slot cycles, and wherein at least one of the frame and slot cycles of the second transmission is different from the first transmission; and

dynamically distributing slot events of the second transmission to the slots available in the second transmission protocol depending on the slot events of the first transmission protocol, said dynamic distribution being implemented using a deterministic slot-hopping sequence established by a pseudo-random sequence.

16. The method according to claim 15, wherein the slot-hopping sequence is derived from an identity code used in the second transmission protocol.

17. The method according to claim 15, wherein the dynamic distribution is performed so that a plurality of mutually-independent links exist between at least the first and second link paths.

18. The method according to claim 17, wherein the slot-hopping sequence occurs in a time-shifted manner for each link.

19. The method according to claim 15, wherein the first transmission protocol is a Bluetooth protocol.

20. The method according to claim 19, wherein the Bluetooth transmission transmits at least some data as HTML Viewer 3 (HV3) data packets.

21. The method according to claim 15, wherein the second transmission protocol is a TDMA-based protocol.

22. The method according to claim 21, wherein the TDMA-based protocol is a Worldwide Digital Cordless Telecommunications (WDCT) transmission with 10 slots per frame.

23. The method according to claim 15, wherein a dummy bearer received from the second transmission is determined using an evaluation of slot events on at least two receive slots.

24. The method according to claim 15, wherein individual slots each run through independent frequency-hopping sequences.

25. A transmission device for simultaneously operating on at least two wireless link paths, having respectively different first and second transmission protocols, wherein at least some of carrier frequencies of the at least two wireless link paths overlap, comprising:

parts for transmitting a first transmission from a first of the at least two wireless link paths, said first transmission comprising first data in a sequence of frames subdivided into a plurality of slots, wherein the first data has defined frame and slot cycles, and wherein the first transmission protocol is isochronous;

parts for transmitting a second transmission from a second of the at least two wireless link paths simultaneously with the first transmission, said second transmission comprising second data in a sequence of frames subdivided into a plurality of slots, wherein the second data has defined frame and slot cycles, and wherein at least one of the frame and slot cycles of the second transmission is different from the first transmission; and

a slot allocation device that dynamically distributes slot events of the second transmission to the slots available in the second transmission protocol depending on the slot events of the first transmission protocol, said dynamic distribution being implemented using a deterministic slot-hopping sequence established by a pseudo-random sequence.

26. A receiving device for simultaneously operating on at least two wireless link paths, having respectively different first and second transmission protocols, wherein at least some of carrier frequencies of the at least two wireless link paths overlap, comprising:

parts for receiving a first transmission from a first of the at least two wireless link paths, said first transmission comprising first data in a sequence of frames subdivided into a plurality of slots, wherein the first data has defined frame and slot cycles, and wherein the first transmission protocol is isochronous;

parts for receiving a second transmission from a second of the at least two wireless link paths simultaneously with the first transmission, said second transmission comprising second data in a sequence of frames subdivided into a plurality of slots, wherein the second data has defined frame and slot cycles, and wherein at least one of the frame and slot cycles of the second transmission is different from the first transmission; and

a slot evaluation device that dynamically distributes slot events of the second transmission to the slots available in the second transmission protocol depending on the slot events of the first transmission protocol, said dynamic distribution being implemented using a deterministic slot-hopping sequence established by a pseudo-random sequence.
