Uplink Physical Layer Functions
This chapter describes the physical layer protocols and functional processing in LTE/LTE-Advanced uplink direction. The physical layer is the lowest protocol layer in baseband signal processing that interfaces with the physical media through which the signal is transmitted and received. The physical layer receives MAC PDUs (transport blocks) and processes them through channel coding, interleaving, baseband modulation, layer mapping for multi-antenna operation, eigen-precoding, resource element and antenna mapping.
