Patent ID: 7929410

Claim:
A wireless transmit/receive unit (WTRU) comprising: a first memory; a second memory; a protocol stack having a medium access control (MAC) layer and a radio link control (RLC) layer configured to transmit at least one control word, the at least one control word including instructions for transferring data between the first memory and the second memory and for reformatting the data while the data is being transferred between the first memory and the second memory; and a protocol engine configured to receive the control word transmitted by the protocol stack, and in response to receipt of the control word, construct MAC service data units (SDUs) from received RLC SDUs and construct MAC protocol data units (PDUs) from MAC SDUs based on control parameters from the control word, transfer the MAC PDUs from the first memory to the second memory according to the instructions included in the received control word, wherein the control word specifies parameters including radio link control (RLC) delivery protocols (SEP), high speed uplink packet access (HSUPA) scheduling and rate calculation, enhanced dedicated channel (E-DCH) transport format combination (E-TFC) restriction and selection and dedicated channel MAC (MAC-d) flow multiplexing.
