Classification: CPC H | IPC H

Claim 4:
5. A method of an user device, the method comprising:
receiving resource allocation information from a base station, the resource allocation information corresponding to first contiguous resource blocks allocated to the user device;
communicating with the base station using the first contiguous resource blocks starting from a first resource block at a first slot in a first subframe and using second contiguous resource blocks starting from a second resource block at a second slot in the first subframe; and
communicating with the base station using third contiguous resource blocks starting from a third resource block at a first slot in a second subframe and using fourth contiguous resource blocks starting from a fourth resource block at a second slot in the second subframe;
wherein a position of the first resource block is the same as a position of the second resource block in a frequency axis,
wherein a position of the third resource block is the same as a position of the fourth resource block in the frequency axis,
wherein a number of the first contiguous resource blocks is the same as a number of the second contiguous resource blocks, a number of the third contiguous resource blocks and a number of the fourth contiguous resource blocks,
wherein the position of the first resource block in the frequency axis is determined by applying an expression in the form A mod B,
wherein A is determined by summing a first parameter and a second parameter,
wherein the first parameter is obtained from the resource allocation information,
wherein the second parameter is determined based on a first hopping function multiplied by a number of contiguous resource block for each sub-bands S,
wherein B is determined based on a total number of resource blocks forming an uplink bandwidth,
wherein the position of the third resource block in the frequency axis is determined by applying an expression in the form C mod D,
wherein C is determined by summing a third parameter and a fourth parameter,
wherein the third parameter is obtained from the resource allocation information,
wherein the fourth parameter is determined based on a second hopping function multiplied by the number of contiguous resource block for each sub-bands S, and
wherein D is determined based on the total number of resource blocks forming an uplink bandwidth.
