Frequency hopping in license-exempt/shared bands

A method, comprising:

• utilizing radio resource control signaling to configure a user device for N secondary cells on license-exempt channels wi in a frequency hopping channel set W={wi} where i=1, 2, . . . N, in which N is an integer at least equal to one, each of the N secondary cells occupies a number of one or more of the channels the channels wi are equal bandwidth, and the number of channels is configurable by an access node per secondary cell;
• utilizing cross-carrier scheduling on a primary cell to schedule a frequency hopping resource block hi on the ith license-exempt channel wi on at least one of the N secondary cells;
• and
• adapting parameters for the frequency hopping based on measurements of at least some of the license-exempt channels wi received from at least the user device.

A computer readable memory storing a set of instructions, which when executed by an apparatus causes the apparatus to:

• utilize radio resource control signaling to configure a user device for N secondary cells on license-exempt channels wi in a frequency hopping channel set where W={wi} where i=1, 2, . . . N, in which N is an integer at least equal to one, each of the N secondary cells occupies a number of one or more of the channels wi, the channels wi are equal bandwidth and the number of channels is configurable by an access node per secondary cell;
• utilize cross-carrier scheduling on a primary cell to schedule a frequency hopping resource block hi on the ith license-exempt channel wi on at least one of the N secondary cells;
• and
• adapt parameters for the frequency hopping based on measurements of at least some of the license-exempt channels wi received from at least the user device.
