Method and system for decoding
First Claim
Patent Images
1. A method of decoding, the method comprising:
- receiving one or more subpackets;
determining whether one or more decoding resources have fallen below a threshold;
determining whether a measured pilot signal-to-noise ratio, averaged over a duration of time slots when the one or more subpackets were received, is lower than a power control setpoint by a predetermined amount;
avoiding an attempt to decode an original packet from the received one or more subpackets if one or more decoding resources have fallen below the threshold and the measured pilot signal-to-noise ratio is lower than the power control setpoint by the predetermined amount; and
attempting to decode the original packet from the received one or more subpackets if either one or more decoding resources have not fallen below the threshold or if the measured pilot signal-to-noise ratio is above the power control setpoint by the predetermined amount.

Abstract
Methods and apparatus to decode encoded data. One method starts and stops turbo decoding depending on channel conditions of a received pilot signal. One method may be used with Hybrid Automatic Repeat Request (H-ARQ).

11. A system comprising:
-
means for receiving one or more subpackets; means for determining whether one or more decoding resources have fallen below a threshold; means for determining whether a measured pilot signal-to-noise ratio, averaged over a duration of time slots when the one or more subpackets were received, is lower than a power control setpoint by a predetermined amount; means for avoiding an attempt to decode an original packet from the received one or more subpackets if one or more decoding resources have fallen below the threshold and the measured pilot signal-to-noise ratio is lower than the power control setpoint by the predetermined amount; and means for attempting to decode the original packet from the received one or more subpackets if either one or more decoding resources have not fallen below the threshold or if the measured pilot signal-to-noise ratio is above the power control setpoint by the predetermined amount. - View Dependent Claims (12, 13, 14, 15)

16. A tangible storage medium having stored thereon processor-executable software instructions configured to cause a processor to perform steps comprising:
-
receiving one or more subpackets; determining whether one or more decoding resources have fallen below a threshold; determining whether a measured pilot signal-to-noise ratio, averaged over a duration of time slots when the one or more subpackets were received, is lower than a power control setpoint by a predetermined amount; avoiding an attempt to decode an original packet from the received one or more subpackets if one or more decoding resources have fallen below the threshold and the measured pilot signal-to-noise ratio is lower than the power control setpoint by the predetermined amount; and attempting to decode the original packet from the received one or more subpackets if either one or more decoding resources have not fallen below the threshold or if the measured pilot signal-to-noise ratio is above the power control setpoint by the predetermined amount. - View Dependent Claims (17, 18, 19, 20)
