Question: What compression strategy does the UDC protocol, utilized in PDCP for NR (New Radio), employ based on IETF specifications?
Option 1: Static Huffman coding tree as defined in IETF RFC 1951
Option 2: Dynamic Arithmetic Coding as per IETF RFC 1979
Option 3: LZ77 Sliding Window Algorithm without predefined coding trees
Option 4: Adaptive Dictionary Encoding as outlined in IETF RFC 1980
Explanation: The UDC protocol, for efficient data compression in NR (New Radio) PDCP contexts, specifically adopts the Static Huffman coding tree strategy. This approach is directly mandated by the IETF's DEFLATE Compressed Data Format Specification (RFC 1951), ensuring a standardized and effective method for compressing data blocks while maintaining byte-alignment through Z_SYNC_FLUSH, tailored for wireless telecommunications' stringent requirements.
