Abstract
There is provided a method of controlling access to a shared wireless medium in a first wireless communication system based on a contention-based protocol for medium access involving carrier sensing, wherein the first wireless communication system is of a first radio access technology. The method comprises determining (S1) whether a second wireless communication system of a second, different radio access technology is operating on the same channel of the shared wireless medium as the first wireless communication system. The method also comprises initiating (S2), if the second wireless communication system is operating on the same channel, a change of a carrier-sensing threshold used in the first wireless communication system for determining, for at least one communication unit, whether the medium is available for access from a first level to a second, different level.

34. A method of controlling access to a shared wireless medium in a first wireless communication system based on a contention-based protocol for medium access involving carrier sensing, wherein the first wireless communication system is of a first radio access technology, the method comprising:
-
determining whether a second wireless communication system of a second, different, radio access technology is operating on the same channel of the shared wireless medium as the first wireless communication system; and initiating, in response to determining that the second wireless communication system is operating on the same channel, a change of a carrier-sensing threshold used in the first wireless communication system for determining, for at least one communication unit, whether the medium is available for access, from a first level to a second, different level. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

51. A network node configured to control access to a shared wireless medium in a first wireless communication system based on a contention-based protocol for medium access involving carrier sensing, wherein the first wireless communication system is of a first radio access technology, the network node comprising a processing circuit configured to:
-
determine whether a second wireless communication system of a second, different radio access technology is operating on the same channel of the shared wireless medium as the first wireless communication system; and initiate, in response to determining that the second wireless communication system is operating on the same channel, a change of a carrier-sensing threshold used in the first wireless communication system for determining, for at least one communication unit, whether the medium is available for access, from a first level to a second, different level. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A computer-readable medium comprising, stored thereupon, a computer program for controlling, when executed by at least one processor, access to a shared wireless medium in a first wireless communication system based on a contention-based protocol for medium access involving carrier sensing, wherein the first wireless communication system is of a first radio access technology,
wherein the computer program comprises instructions, which when executed, cause the at least one processor to: -
determine whether a second wireless communication system of a second, different radio access technology is operating on the same channel of the shared wireless medium as the first wireless communication system; and initiate, in response to determining that the second wireless communication system is operating on the same channel, a change of a carrier-sensing threshold used in the first wireless communication system for determining, for at least one communication unit, whether the medium is available for access from a first level to a second, different level.
