Patent ID: 8503423

Claim:
A method for multiplexing service data units (SDUs) in a medium access control (MAC) protocol data unit (PDU) for transmission over a high speed-downlink shared channel (HS-DSCH), the method comprising: creating one or more reordering PDUs, each reordering PDU including one or more reordering SDUs, wherein a reordering SDU is a complete MAC enhanced high speed (MAC-ehs) SDU or a segment of a MAC-ehs SDU; creating a MAC-ehs header for the MAC PDU, the MAC-ehs header comprising: a logical channel indicator (LCID) field indicating a logical channel for each of the one or more reordering SDUs; a length indicator (LI) field indicating a length of each of the one or more reordering SDUs; and a segmentation indication (SI) field for each of the one or more reordering PDUs indicating: whether a first reordering SDU in the reordering PDU is a complete MAC-ehs SDU or a last segment of a MAC-ehs SDU, and whether a last reordering SDU in the reordering PDU is a complete MAC-ehs SDU or the first segment of a MAC-ehs SDU; and transmitting the MAC PDU.
