Power boosting in a wireless communication system
First Claim
Patent Images
1. A method for transmission of packetized data in a wireless communication system having a designated packet error rate, the method comprising:
- determining a first number of installments for transmission of a first subpacket of data;
power boosting transmissions of a second number of installments of the first subpacket of data, wherein the second number is less than the first number, wherein the second number is selected to satisfy the designated packet error rate; and
terminating transmission of the first subpacket of data after the second number of installments.

Abstract
Method and apparatus for power boosting a portion of installments in transmission of a packet of data. The power boosting incorporates a power boost factor for each installment. On receipt of a negative acknowledgement after the power boosted portion of installments, transmission of the subpacket is terminated, and processing passed to a higher layer.

15. A base station apparatus comprising:
-
a packet processing unit adapted to receive data for transmission and generate subpackets, each of the subpackets transmitted in a number of installments;
a power boost unit adapted to apply a power boost factor to a portion of the subpackets, an acknowledgement message processing unit adapted to terminate transmission of installments for a subpacket on receipt of an acknowledgement message; and
a transmitter for transmitting power boosted subpackets, wherein the packet processing unit terminates processing of the subpacket on receipt of a negative acknowledgement message after the portion of the subpackets is transmitted.

16. A method for transmission from a mobile station in a wireless communication system, wherein each data packet received is transmitted in a number of installments, the method comprising:
-
transmitting a first negative acknowledgement message for a last installment of a first subpacket, the first negative acknowledgement transmitted at a first time slot; and
transmitting a second negative acknowledgement message for the last installment of the first subpacket, the second negative acknowledgement transmitted at a second time slot, wherein the second time slot is designated for the first subpacket of the next packet. - View Dependent Claims (17)
