11. The apparatus of claim 5 , the apparatus being configured to select a different given number for different devices, device groups or cells utilising the same shared channel.
12. A method, comprising:
wirelessly communicating on a synchronised shared channel having a frame structure comprising symbols;
receiving from a network element a given number for each frame or sub frame, wherein the given number received for a first frame or sub frame is different than the given number received for a subsequent second frame or sub frame, and
during the given number of symbol periods in the beginning of a frame or sub frame measuring interference and making a decision whether to transmit or not during the rest of the symbol periods of the frame or sub frame such that interference is measured for a different number of symbol periods in the first frame or sub frame than in the second frame or sub frame.
13. The method of claim 12 , further comprising:
receiving from a network element a given number for a predetermined number of successive frames or sub frames.
14. The method of claim 12 , further comprising:
communicating on a shared channel having a frame structure comprising a predetermined number of sub frames within each frame, and
receiving from a network element a given number for each sub frame of the frame.
15. The method of claim 12 , further comprising:
receiving from a network element given numbers for different trans-mission directions.
16. A method, comprising:
controlling a set of devices, device groups or cells configured to utilise a synchronised shared channel in wireless communication, the channel having a frame structure comprising symbols and during a given number of symbol periods in the beginning of a frame or sub frame to measure interference and make a decision whether to transmit or not during the rest of the symbol periods of the frame or sub frame; and
selecting a given number for each frame or sub frame for devices, device groups or cells utilising the same shared channel, wherein the given number selected for a first frame or sub frame is different than the given number selected for a subsequent second frame or sub frame such that interference is measured for a different number of symbol periods in the first frame or sub frame than in the second frame or sub frame.
