Patent ID: 8649351

Claim:
A method for use in a wireless cellular communications system, according to which method a controlling node controls transmissions to and from users in a cell, and transmissions are made in subframes with a certain extension in time and over a certain amount of subcarriers (Δf) in frequency, said subframes comprising a number of subelements, the method being used for scheduling a first and a second channel in one and the same subframe, the method comprising the steps of: dividing transmission resources needed for the first channel into a first set of resource groups; assigning the resource groups of the first set to subelements in the subframe in a predetermined fashion, wherein each subelement comprises a group of four time-frequency resource elements; assigning a numeric value to all subelements in the subframe which have not been assigned a resource group of the first set, wherein a number of subelements that have not been assigned a resource group of the first set is equal to N; dividing transmission resources needed for the second channel into a second set of resource groups; and assigning, in a predetermined fashion, the resource groups of the second set to subelements in the subframe by means of said numeric values, wherein assigning the resource groups of the second set comprises: determining a respective numeric value for one or more resource groups of the second set based on the number of subelements (N) in the subframe which have not been assigned a resource group of the first set; and assigning each resource group of the second set to a subelement associated with a respective numeric value determined for that resource group.
