Abstract
Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers. Packets targeted for FF may be divided into independently decodable CWs that may be transmitted in the next hop, for example, as soon as the destination is determined without waiting for an entire packet's arrival and/or for CRC verification. Low latency (e.g. FF) traffic may be indicated. CW-based FF may be extensible for an e2e RAN path from a WTRU to the last access node in a RAN. Intermediate metrics, a packet CRC and/or a per-CW CRC may be utilized for data integrity. HARQ and/or CW retransmission procedures may be implemented between network nodes for error handling.
