DATA TRANSMISSION VIA A RELAY STATION IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for wireless communication, comprising:
- sending a first transmission of a packet from a transmitter station to a receiver station;
receiving no acknowledgement (ACK) information for the first transmission of the packet at the transmitter station;
suspending transmission of the packet by the transmitter station in response to receiving no ACK information for the first transmission of the packet;
receiving from the receiver station an indication to resume transmission of the packet; and
sending a second transmission of the packet from the transmitter station to the receiver station in response to receiving the indication.

Abstract
Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.

19. A method for wireless communication, comprising:
-
receiving a first transmission of a packet sent from a transmitter station to a receiver station; determining that transmission of the packet has been suspended by the transmitter station due to the transmitter station receiving no acknowledgement (ACK) information for the first transmission of the packet; sending to the transmitter station an indication to resume transmission of the packet; and receiving a second transmission of the packet sent from the transmitter station to the receiver station in response to the indication. - View Dependent Claims (20, 21)
