An intermediate station and method for facilitating handover in a multi-hop communications system is disclosed. The method may include receiving a handover trigger, finding a target station to receive handover, determining whether the handover requires a timing change, wherein if it is determined that a preamble and broadcast timing change for one or more downstream stations is required, estimating when the handover will take place, instructing the one or more downstream stations to resynchronize, and performing the handover to the target station.

Intermediate station and method for facilitating handover in a multi-hop communication system

A radio communication system with adaptive interleaving selects between chip interleaving and bit interleaving depending upon the number of active code signals. A transmitted RF signal includes a coded information signal part and a control signal part that indicates a number of active code signals that have been combined to form the coded information signal part. The system is especially suited for MC-CDMA systems.
