Abstract  Abstract

Soft handoff in an OFDMA system is disclosed. If the pilot signal strength for a base station exceeds the defined threshold the base station is added to an active set list. Subcarriers in a plurality of orthogonal frequency division multiplexing (OFDM) symbols are divided and allocated into subchannels. The OFDM symbols are divided and multiplexed. A soft handoff zone with a first dimension of the subchannels and a second dimension of the divided and multiplexed OFDM symbols is defined. The soft handoff zone has subcarriers with a subchannel definition for example an identical permutation.
