System and method for apriori decoding

摘要

Embodiments are provided for transmitting channel information, such as control channel information, using lower resources at the transmitter combined with using apriori information associated with channel information in the decoder of the receiver. The apriori information represent predictable information that can be predicted by the receiver and is not transmitted with the channel information by the transmitter. The transmitter determines the apriori information for the channel and codes the channel information into bits and fields excluding the apriori information. Upon receiving the channel information, the receiver determines the apriori information associated in accordance with previously received information. The apriori information is then provided as probability information for input to the decoder. The decoder then decodes the received information in accordance with the apriori information.

1. A method by a receiver for utilizing apriori information in a decoder, the method comprising:
receiving, at an input of the receiver, information associated with a control channel; determining the apriori information in accordance with the received information and previously received information associated with the control channel; and decoding the received information at the decoder using the determined apriori information as probability information.
