Apparatus and method for transmitting frame information in multi-hop relay broadband wireless access communication system
First Claim
1. An upper node in a wireless communication system using a relay scheme, the upper node comprising:
- a receiver configured to receive a request of a lower relay station for an initial connection of the lower relay station; and
a transmitter configured to transmit, during an initial connection procedure, downlink sub-frame configuration information,wherein the downlink sub-frame configuration information comprises a number of zones indicating a number of sections included in a downlink sub-frame and per-zone configuration information, andwherein the per-zone configuration information comprises at least one of a transceiver mode indicating one of a transmission (TX) mode, a reception (RX) mode, and an idle mode in each zone, a symbol offset indicating a start point of each zone, and a duration starting from the symbol offset.

Abstract
An upper node is provided for use in a wireless communication system using a relay scheme. The upper node includes means for transmitting, upon a request of a lower relay station for an initial connection of the lower relay station, downlink section information for communication with the lower relay station for a relay service to the lower relay station; and means for transmitting, after the initial connection with the lower relay station, frame configuration information for communication with the lower relay station for a relay service to the lower relay station through the downlink section. The downlink section information includes configuration information of the downlink section for communication with the lower relay station for a relay service.

21. An upper node in a wireless communication system using a relay scheme, the upper node comprising:
-
a processor configured to generate a control message indicating uplink sub-frame configuration information for communication with a lower relay station for a relay service, the control message including one of a Downlink Channel Descriptor (DCD), a Media Access Control (MAC) message, and a Media Access Protocol (MAP) message including the uplink sub-frame configuration information in a format of an information element; and a transceiver configured to transmit the control message to the lower relay station and communicate with the lower relay station using the uplink sub-frame configuration information transmitted to the lower relay station, wherein the uplink sub-frame configuration information comprises a number of zones indicating a number of sections included in an uplink sub-frame and per-zone configuration information, and wherein the per-zone configuration information comprises at least one of a transceiver mode indicating one of a transmission (TX) mode, a reception (RX) mode, and an idle mode in each zone, a symbol offset indicating a start point of each zone, and a duration starting from the symbol offset. - View Dependent Claims (22)
