Abstract
A user apparatus having a primary cell on a licensed band is requested to scan an unlicensed band, the scanning being performed with a raster. The thus obtained availability of the unlicensed band is used for determining a secondary cell. To improve the reparation of the traffic between the primary cell and the secondary cell, timing information measurements are carried out which can be exploited to avoid interferences between the primary and the secondary cell.

22. A method comprising:
-
providing a primary cell on a licensed band to a user apparatus; sending, to the user apparatus, a message indicating a request to scan an unlicensed band with a raster; receiving, from the user apparatus, scan results indicating one or more cells on the unlicensed band, and timing information measurements on the one or more cells on the unlicensed band; using the scan results to select a carrier frequency for a secondary cell on the unlicensed band; using received timing information measurements for determining timing information for the secondary cell; and sending, to a network apparatus providing the secondary cell, information on the secondary cell and the timing. - View Dependent Claims (23, 24, 25, 26, 27)

28. A method comprising:
-
receiving, over a primary cell on a licensed band, from a network apparatus providing the primary cell, a request to scan an unlicensed band; scanning the unlicensed band using a raster; sending as scan results information on one or more found cells on the unlicensed band and timing information measurements on the one or more found cells on the unlicensed band to the network apparatus. - View Dependent Claims (29, 30, 31, 32)

33. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to; provide a primary cell on a licensed band to a user apparatus; send, to the user apparatus, a message indicating a request to scan an unlicensed band with a raster; receive, from the user apparatus, scan results indicating one or more cells on the unlicensed band and timing information measurements on one or more cells on the unlicensed band; use the scan results to select a carrier frequency for a secondary cell on the unlicensed band; use the received timing information measurements to determine timing information for the secondary cell; and send, to a network apparatus providing the secondary cell, information on the secondary cell and the timing. - View Dependent Claims (34, 35)

36. A method, comprising:
-
receiving, over a primary cell on a licensed band, from a network apparatus providing the primary cell, a request to scan an unlicensed band; scanning the unlicensed band using a raster; and sending as scan results information on one or more found cells on the unlicensed band and timing information measurements on the one or more found cells on the unlicensed band to the network apparatus. - View Dependent Claims (37, 38, 39)

40. A computer program product comprising a program code stored in a non-transitory computer-readable medium, said program code, when run on a computer, configures the computer to:
-
receive, over a primary cell on a licensed band, from a network apparatus providing the primary cell, a request to scan an unlicensed band; scan the unlicensed band using a raster; and send as scan results information on one or more found cells on the unlicensed band and timing information measurements on the one or more found cells on the unlicensed band to the network apparatus.
