Relay frame structure for supporting transparent and bidirectional relays
First Claim
1. A method for transmitting data, the method comprising:
- receiving at a first relay station first data from a parent station during a downlink period comprising a plurality of downlink zones, wherein a network coding zone is one of the plurality of downlink zones and is located at an end of the downlink period, and wherein the first data is received in at least one of the plurality of downlink zones other than the network coding zone;
receiving at the first relay station from a child station, second data during an uplink zone;
transmitting third data by the first relay station to the child station, during the network coding zone using a resource; and
transmitting the third data to the parent station, during the network coding zone, using the resource, wherein the third data transmitted to the child station and the parent station results from the first data being effectively logically XOR-ed to the second data.

Abstract
A method for transmitting data includes receiving at a first relay station first data from a parent station during a downlink period comprising a plurality of downlink zones. A network coding zone is one of the plurality of downlink zones and is located at an end of the downlink period, and the first data is received in at least one of the plurality of downlink zones other than the network coding zone. The method further includes receiving at the first relay station from a child station, second data during an uplink zone, and transmitting third data by the first relay station to the child station, during the network coding zone using a resource. The method further includes transmitting the third data to the parent station, during the network coding zone, using the resource. The third data results from the first data being effectively logically XOR-ed to the second data.

7. A method for transmitting data at a relay station (RS) using a Time Division Duplex (TDD) frame structure comprising a plurality of TDD frames, each of the TDD frames comprising a downlink (DL) period and an uplink (UL) period, in a wireless communication system, the method comprising:
-
receiving first data from a child station during a first UL zone of a plurality of UL zones of the UL period, wherein the first UL zone is located at a beginning of the UL period; and transmitting second data to a parent station during a second UL zone of the plurality of UL zones of the UL period, wherein the second UL zone is located at an end of the UL period, wherein, in each of the plurality of TDD frames, a gap zone of the UL period is located between the first UL zone and the second UL zone such that the first UL zone is immediately followed by the gap zone and the gap zone is immediately followed by the second UL zone. - View Dependent Claims (8, 9, 10)
