Title:
UPLINK DATA COMPRESSION TRANSACTION FLOW
Document Type and Number:
WIPO Patent Application WO/2019/086032
Kind Code:
A1
Abstract:
A method of uplink data compression (UDC) error handling is proposed to handle (UDC) error and to maintain compression memory synchronization between a transmitter and a receiver. Specifically, (UDC) checksum operation is proposed to maintain compression memory synchronization between compressor at the transmitter and decompressor at the receiver. The transmitter attaches a checksum to each (UDC) packet and keeps processed uncompressed data in a compression memory. The receiver decompresses each (UDC) packet and keeps processed uncompressed data in a compression memory. If the (UDC) compression memory is unsynchronized and a checksum mismatch is detected, the receiver sends an error indication to the transmitter, which resets its compression memory. The transmitter sends a reset indication to the receiver to reset its compression memory. The (UDC) compression memory is re-synchronized and (UDC) is restarted from the beginning.
