Abstract
Techniques for performing ciphering and re-ordering using a single full sequence number are described. A transmitter ciphers input packets to obtain ciphered packets, with each input packet being ciphered with a full sequence number. The transmitter generates output packets for the ciphered packets, with each output packet including a partial sequence number used for re-ordering and derived from the full sequence number. The full sequence number may be incremented for each input packet or each byte of each packet. The partial sequence number may be used as a sequence number for RLC and may be used for re-ordering, duplicate detection, error correction, and/or other functions. A receiver performs the complementary processing, re-orders received packets based on the partial sequence number included in each packet, and deciphers the received packets using the partial sequence number included in each received packet.
