Abstract
The present disclosure relates generally to systems and methods for random access in a wireless communication system. In one example, the method includes allocating first and second random access orthogonal frequency subbands to first and second subdivisions, respectively, in a wireless communication network. The first subband is assigned to a first position in a first subframe for use in the first subdivision during a first transmission slot, and the second subband is assigned to a second position in the first subframe for use in the second subdivision during the first transmission slot. The first subband is then assigned to a third position in a second subframe for use in the first subdivision during a second transmission slot following the first transmission slot, and the second subband is assigned to a fourth position in the second subframe for use in the second subdivision during the second transmission slot.
