Abstract

Packet data convergence protocol (PDCP) layer encoding and decoding procedures for use in cell-free networks are disclosed. A transmitter (e.g., a user equipment (UE) or a cluster of base stations that serves a UE) performs PDCP processing using a PDCP entity by: generating a concatenated service data unit (SDU) set by concatenating a plurality of SDUs for a protocol data unit (PDU) set; segmenting the concatenated SDU set into one or more systematic PDUs of the PDU set; performing an encoding with the one or more systematic PDUs to generate one or more redundant PDUs of the PDU set; and distributing the one or more systematic PDUs and the one or more redundant PDUs across one or more radio link control (RLC) entities for transmission. Complimentary processes performed by a PDCP entity of a receiver (e.g., a cluster of base stations or a UE) are also disclosed.
