Abstract
Iterative sequential selection techniques can be used to efficiently compute RB assignment sequences in relay-assisted networks. Embodiment techniques construct a graphical representation of a cyclic group based on a selected pattern in a set of patterns and a selected cyclic-shift in a plurality of cyclic shifts. Remaining patterns are placed in a unitary group, and an iterative sequential selection technique is used to evaluate the remaining patterns in the unitary group for each of the cyclic shifts over a sequence of iterations, thereby complete the list of RB assignment sequences. At the end of each iteration, a new RB assignment sequence is added based on the pattern, cyclic shift tuple producing the fewest collisions with occupied resource blocks of the graphical representation.
