1. A method, comprising:

  • determining, by a network element, a plurality of access points, wherein the plurality of access points belong to a cluster set of a user device; and

    allocating a plurality of random-access-channel slots to the plurality of access points such that the plurality of random-access-channel slots are staggered in time over a random-access-channel period within a frame structure used by the user device, wherein a position of the plurality of random-access-channel slots within a sub-frame of the random-access-channel period is determined according to an integer corresponding to a number of access points of the plurality of access points in the cluster set multiplied by ten, and adding a value of one to a product of the multiplication.
