Management and setup of enhanced mac-e/es resources in cell-fach stateManagement and setup of enhanced mac-e/es resources in cell-fach state description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090135771, Management and setup of enhanced mac-e/es resources in cell-fach state. Brief Patent Description - Full Patent Description - Patent Application Claims
This application claims the benefit of U.S. Provisional Patent Appl. No 60/982,528, filed Oct. 25, 2007 and U.S. Provisional Patent Appl. No. 61/018,567, filed Jan. 2, 2008 which are incorporated by reference as if fully set forth. This application is related to wireless communications. An enhanced uplink mechanism has been introduced for the Third Generation Partnership Project (3GPP) standards. As a part of the enhanced uplink mechanism and improved Layer 2 (L2), new functional entities have been introduced in the medium access control (MAC) including enhanced MAC-e/es entities. In a wireless transmit/receive unit (WTRU), the enhanced MAC-e/es are considered one single sublayer. However in the network side the enhanced MAC-e and the enhanced MAC-es entities may be considered separate, with the enhanced MAC-e residing in the Node-B and the enhanced MAC-es residing in the serving radio network controller (SRNC). One enhanced MAC-e and one enhanced MAC-es entity are present for each WTRU in the Node B and in the SRNC, respectively. The entities are separate in the network so that the more real-time critical functionality of enhanced MAC-e may be placed into the Node-B. The HARQ module performs the MAC functions relating to the HARQ protocol, including storing enhanced MAC-e payloads and re-transmitting them. The HARQ module determines the E-TFC, the retransmission sequence number (RSN), and the power offset to be used by Layer 1 (L1). The multiplexing and TSN module concatenates multiple MAC-d protocol data units (PDUs) into enhanced MAC-es PDUs, and multiplexes one or multiple enhanced MAC-es PDUs into a single enhanced MAC-e PDU, to be transmitted in a subsequent transmission time interval (TTI), as instructed by the E-TFC selection module. The E-TFC selection module performs E-TFC selection according to scheduling information, relative and absolute grants received from a UMTS Terrestrial Radio Access Network (UTRAN) via L1 signalling, and a serving grant signalled through the RRC for arbitration among the different flows mapped on the E-DCH. The segmentation module performs segmenting of the MAC-d PDUs. The reordering queue distribution module routes the enhanced MAC-es PDUs to the correct reordering buffer based on the serving radio network controller (SRNC) configuration and based on the logical channel identity. The reordering/combining module reorders received enhanced MAC-es PDUs according to the received TSN and Node-B tagging, (i.e. CFN, subframe number). Enhanced MAC-es PDUs with consecutive TSNs are delivered to the disassembly module upon reception. The macro diversity selection module operates in the enhanced MAC-es, in case of soft handover with multiple Node-Bs. The disassembly module is responsible for disassembly of enhanced MAC-es PDUs, including removal of the enhanced MAC-es header. The reassembly function reassembles segmented MAC-d PDUs, and delivers the MAC-d PDUs to the correct MAC-d entity. Referring to The E-DCH scheduling module manages E-DCH cell resources between WTRUs. Based on scheduling requests, scheduling grants are determined and transmitted. The E-DCH control module is responsible for reception of scheduling requests and transmission of scheduling grants. The de-multiplexing module performs the de-multiplexing of enhanced MAC-e PDUs into enhanced MAC-es PDUs. Enhanced MAC-es PDUs are forwarded to the SRNC in their associated MAC-d flow.
