Adaptive Partial Packet Decoding

摘要

A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

1. A method performed by a wireless communication device, the method comprising:
in response to a start of a transmission interval for a current packet, selectively allowing or disallowing a partial packet decoding process based on whether or not a first measure of a first quality parameter of a communication link is better than a first quality standard; and when the partial packet decoding process is allowed:
obtaining a second measure of a second quality parameter of the communication link, wherein the second quality parameter is different than the first quality parameter;selectively performing or not performing the partial packet decoding process on the current packet based on whether or not the second measure of the second quality parameter of the communication link is better than a second quality standard.
