Method for Accessing Channels in OFDMA Mobile Multihop Relay Networks
First Claim
1. A method for accessing channels in an orthogonal frequency division multiple access (OFDMA) mobile multihop relay wireless network, comprising:
- partitioning a downlink subframe of a frame in an OFDMA-based mobile multihop relay wireless network into at least one downlink access zone and a set of downlink relay zones, in which the network includes a base station, a set of relay station and a set of mobile stations;
partitioning an uplink subframe of the frame into at least one uplink access zone and a set of uplink relay zones;
transmitting, during the downlink access zone, from the base station and the relay stations only to the set of mobile stations;
transceiving, during the downlink relay zone, between the base station and the set of relay stations, while the mobile stations associated with the base station and the set of relays stations are idle;
transmitting, during the uplink access zone, only from the set of mobile stations to set of relay stations and the base station; and
transceiving, during the uplink relay zone, between the base station and the set of relay stations, while the mobile stations associated with the base station and the set of relays stations are idle.

Abstract
A method accesses channels in an OFDMA mobile multihop relay wireless network. The method partitions a downlink sub-frame into at least one downlink access zone and a set of downlink relay zones. The uplink subframe is partitioned into at least one uplink access zone and a set of uplink relay zones. During the downlink access zone, the base station and the relay stations transmit only to the set of mobile stations. During the downlink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle. During the uplink access zone, the set of mobile stations transmit only to the set of relay stations and the base station. During the uplink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle.
