摘要： 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.

摘要： Time synchronization of an access point base station. The method may include receiving an assignment message from a service provider comprising a plurality of parameters. The plurality of parameters may include an access point base station frequency assignment, a network identifier, an access point base station identifier, a neighbor list, a PN offset, and/or a scrambling code. The access point base station may then synchronize with the macro base station. Synchronizing may include searching for a strongest macro base station in the neighbor list, synchronizing a long code of the access point base station to the macro base station, estimating a propagation delay between the macro base station and the access point base station, and initializing a state of the access point base station PN code using the propagation delay to provide system time synchronization.

摘要： A method for retransmitting packet data within a wireless communication network includes forming a plurality of subpackets for transmission along a route which was previously used to transmit a missing packet, such that the subpackets collectively include a header portion and a data portion of the missing packet to be retransmitted. The method may further include forming a first subpacket having a header portion and data portion, such that the header portion includes header data associated with a stream and route used to transmit the subpackets, and the data portion includes the header portion of the missing packet and data represented by only some of the data portion of the missing packet. An additional operation forms one or more additional subpackets which each include a header portion having header data associated with the stream and the route, and a data portion that includes only some of the data portion of the missing packet.
