ACKNOWLEDGED MODE RADIO LINK CONTROL ARCHITECTURE AND METHOD WITHIN EVOLVED HSPA SYSTEMS

摘要

An acknowledged mode (AM) radio link control (RLC) architecture and method within evolved high speed packet access (HSPA) are disclosed. The RLC is configured to operate in AM and process protocol data units (PDUs) of flexible size. Specifically, an AM RLC architecture and method in which RLC SDUs are segmented and/or concatenated only at the time of or immediately prior to delivering the PDUs to lower layers. This includes an interface with lower layers in order to support flexible PDU sizes for AM RLC.
