Protocols for Multi-Hop Relay System with Centralized Scheduling
First Claim
1. A method comprising:
- receiving a data transmission from a prior point in a transmission path;
determining if the received data is corrupt;
forwarding the received data to the next point in the transmission path;
transmitting a transmission message to the next point in the transmission path indicating whether or not the received data was corrupt; and
if the data is not corrupt, transmitting a receipt message to the prior point indicating that the data was uncorrupt when received;
wherein the wireless transmission path that includes a user equipment, a base station, and at least one relay station as an intermediate point(s).

Abstract
Various example embodiments are disclosed herein. In an example embodiment, a method of transmitting data via a wireless transmission path that may include a user equipment as a first end point, a base station as second end point, and at least one relay station as an intermediate point(s). The method may include receiving a data transmission from a prior point in the transmission path. Substantially simultaneously: forwarding the received data to the next point in the transmission path, and determining if the received data is corrupt. Transmitting a transmission message to the next point in the transmission path indicating whether or not the received data was corrupt. And, if the data is not corrupt, transmitting a receipt message to the prior point indicating that the data was uncorrupt when received.

9. An apparatus comprising:
-
a transceiver configured to receive a data transmission from a prior point in a transmission path, wherein the transmission path includes a user equipment, a base station, and at least one apparatus as an intermediate point(s); a controller configured to; determine if the received data is corrupt; and the transceiver further configured to; forward the received data to the next point in the transmission path, and transmit a transmission message to the next point in the transmission path, wherein the transmission message indicates whether or not the received data was corrupt, and if the data is not corrupt, to transmit a receipt message to the prior point, wherein the receipt message indicates that the data was uncorrupt when received. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of transmitting data via a wireless transmission path that includes a user equipment, a base station, and at least one relay station as an intermediate point(s), the method comprising:
-
receiving, from the base station, a resource block allocation allowing for the transmission of data to a next point in the transmission path; receiving a data transmission from a prior point in the transmission path, wherein the data transmission includes error detection information; determining, using at least in part the error detection information, if the data is corrupt; and if the data is corrupt, requesting that the data be retransmitted by the prior point of the transmission path, and not using the resource block allocation. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
