    Abstract: A method for assigning a tracking area (TA) is disclosed. A mobility state of a wireless transmit /receive unit (WTRU) is determined and the TA is assigned based on the determined mobility state. Also disclosed is a method for accessing a closed subscriber group (CSG) cell. A CSG TA identifier is received at a WTRU and is stored. A CSG TA broadcast is received and the broadcast CSG TA is accessed if an identifier of the broadcast CSG TA matches the stored CSG TA identifier. Also disclosed is a method for changing a mobility state of a WTRU. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU is examined. The predetermined metric is evaluated to determine if the metric has crossed a threshold and the mobility state is changed based on the evaluated metric. A method for updating TA upon expiration of timer (set up based on mobility state. Paging load).

    Abstract: METHOD AND APPARATUS FOR SELECTING A TRANSPORT FORMAT COMBINATION 5 A METHOD AND APPARATUS FOR SELECTING A TRANSPORT FORMAT COMBINATION (TFC) ARE DISCLOSED. A TFC RECOVERY AND ELIMINATION UNIT GENERATES AN ALLOWED TRANSPORT FORMAT COMBINATION SET (TFCS) SUBSET BY RECOVERING SUPPORTED TFCS AND ELIMINATING NOT SUPPORTED TFCS BASED ON ALLOCATED RADIO RESOURCES AND PARAMETERS 10 THAT ARE NEW. A MULTIPLEXING AND TRANSMISSION SEQUENCE NUMBER JSN) SETTING UNIT GENERATES A MEDIUM ACCESS CONTROL (MAC) PROTOCOL DATA UNIT (PDU) BY MULTIPLEXING AT LEAST ONE HIGHER LAYER PDU WITHIN A MAXIMUM SUPPORTED MAC PDU SIZE. A TFC SELECTION AND PADDING UNIT SELECTS A TFC FOR THE MAC PDU FROM THE ALLOWED TFCS SUBSET AND PERFORMS PADDING OF THE MAC PDU, IF NECESSARY, SO 1 5 THAT THE MAC PDU FITS INTO THE SELECTED TFC. FOR RETRANSMISSION, A NEW ALLOWED TFCS SUBSET MAY BE GENERATED BASED ON NEW RADIO RESOURCES AND PARAMETERS AND THE MAC PDTJ MAY BE FRAGMENTED.

    Abstract: A METHOD AND SYSTEM FOR PERFORMING HANDOVER IN A THIRD GENERATION (3G) LONG TERM EVOLUTION (LTE) SYSTEM ARE DISCLOSED. A SOURCE EVOLVED NODE-B (ENODE-B) MAKES A HANDOVER DECISION BASED ON MEASUREMENTS AND SENDS A HANDOVER REQUEST TO A TARGET ENODE-B(256). THE TARGET ENODE-B SENDS A HANDOVER RESPONSE TO THE SOURCE ENODE-B INDICATING THAT A HANDOVER SHOULD COMMENCE. THE SOURCE ENODE-B (254) THEN SENDS A HANDOVER COMMAND TO A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) (252). THE HANDOVER COMMAND INCLUDES AT LEAST ONE OF RECONFIGURATION INFORMATION, INFORMATION REGARDING TIMING ADJUSTMENT, RELATIVE TIMING DIFFERENCE BETWEEN THE SOURCE ENODE-B (254) AND THE TARGET ENODE-B, INFORMATION REGARDING AN INITIAL SCHEDULING PROCEDURE AT THE TARGET ENODE-B, AND MEASUREMENT INFORMATION FOR THE TARGET ENODE-B AND EXCHANGES LAYER 1/2 SIGNALING TO PERFORM DOWNLINK SYNCHRONIZATION, TIMING ADJUSTMENT, AND UPLINK AND DOWNLINK RESOURCE ASSIGNMENT BASED ON INFORMATION INCLUDED IN THE HANDOVER COMMAND.

    Abstract: A method and a wireless transmit receive unit, WTRU, for performing measurements for cell reselection are disclosed. Priority information is received via a system information broadcast, wherein the priority information is indicative of cell reselection priority information for an inter-radio access technology, RAT, cell associated with a candidate RAT. A relative priority is determined of the inter-RAT cell associated with the candidate RAT with respect to a current cell associated with a current RAT based on the priority information. Furthemore, cell reselection measurements are performed on the inter-RAT cell in the candidate RAT, wherein the cell reselection measurements are performed based on at least one of the inter-RAT cell associated with the candidate RAT having a higher relative priority than the current cell associated with the current RAT, or a quality of the current cell being less than or equal to a predetermined threshold if the inter-RAT cell associated with the candidate RAT does not a have a higher relative priority than the current cell associated with the current RAT.
