Abstract: IN A WIRELESS COMMUNICATION SYSTEM INCLUDING A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) AND AT LEAST ONE NODE-B (104), A METHOD AND APPARATUS IS USED TO SELECTIVELY ENABLE RECEPTION OF THE LEAST ONE DOWNLINK (DL) ENHANCED UPLINK (EU) SIGNALLING CHANNEL ESTABLISHED BETWEEN THE WTRU (102) AND NODE-B(S). DURING THE OPERATION OF AN ENHANCED DEDICATED CHANNEL (E-DCH), THE WTRU MONITORS AT LEAST ONE DL EU SIGNALLING CHANNEL ESTABLISHED BETWEEN THE WTRU AND THE NODE-B(S) (104) ONLY WHEN IT NECESSARY, BASED ON THE WTRU?s KNOWLEDGE OF AT LEAST ONE ESTABLISHED STANDARD PROCEDURE. THE WTRU (102) COORDINATES AND CONSOLIDATES DL SIGNALLING CHANNEL RECEPTION REQUIREMENTS OF A PLURALITY OF CHANNEL ALLOCATION AND/OR DATA TRANSMISSION PROCEDURES CARRIED OUT BY THE WTRU (102) IN ACCORDANCE WITH THE ESTABLISHED STANDARD PROCEDURE. THE WTRU DETERMINES WHETHER TO ENABLE RECEPTION OF AT LEAST ONE SPECIFIC DL SIGNALLING CHANNEL BASED ON THE CONSOLIDATED DL SIGNALLING CHANNEL RECEPTION REQUIREMENTS. FIGURE 1

Abstract: A WIRELESS COMMUNICATION METHOD AND APPARATUS FOR TRANSFERRING BUFFERED ENHANCED UPLINK (EU) DATA FROM A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) (105), I.E., A MOBILE STATION, TO A NODE-B (110). THE EU DATA (205) IS GENERATED AND STORED IN A BUFFER (120) OF THE WTRU (105). THE WTRU (105) TRANSMITS A MESSAGE TO THE NODE-B (110) INCLUDING A REQUEST FOR A DESIRED TRANSPORT FORMAT COMBINATION (TFC) OR DATA TRAFFIC INDICATOR. THE NODE-B (110) SCHEDULES ONE OR MORE ALLOWED EU DATA TRANSMISSIONS (220) BETWEEN THE WTRU (105) AND THE NODE-B (110) BY TRANSMITTING AN EU DATA SCHEDULING MESSAGE (215) TO THE WTRU (105). THE WTRU (105) TRANSMITS ALL OF THE EU DATA (205) STORED IN THE BUFFER (120) TO THE NODE-B (110) IF THE ALLOWED EU DATA TRANSMISSIONS (220) ARE SUFFICIENT TO SUPPORT TRANSMISSION OF ALL OF THE EU DATA (205) STORED IN THE BUFFER (120). OTHERWISE, THE WTRU (105) TRANSMITS A PORTION OF THE EU DATA (205) ALONG WITH THE DESIRED TFC OR DETAILED TRAFFIC VOLUME MEASUREMENT (TVM) INFORMATION TO THE NODE-B (110).

Abstract: A METHOD AND APPARATUS FOR ACCESSING A CONTENTION-BASED UPLINK RANDOM ACCESS CHANNEL (RACH) IN A SINGLE CARRIER FREQUENCY DIVISION MULTIPLE ACCESS (SC-FDMA) SYSTEM ARE DISCLOSED. A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) RANDOMLY SELECTS O A RACH SUBCHANNEL AND A SIGNATURE AMONG A PLURALITY OF AVAILABLE RACH SUBCHANNELS AND SIGNATURES. THE WTRU (500) TRANSMITS A PREAMBLE USING THE SELECTED SIGNATURE VIA THE SELECTED RACH SUBCHANNEL AT A PREDETERMINED OR COMPUTED TRANSMISSION POWER. A BASE STATION (600) MONITORS THE RACH TO DETECT THE PREAMBLE AND SENDS AN ACQUISITION INDICATOR (AI) TO THE WTRU (500) WHEN A SIGNATURE IS DETECTED ON THE RACH. WHEN RECEIVING A POSITIVE ACKNOWLEDGEMENT, THE WTRU (500) SENDS A MESSAGE PART TO THE BASE STATION (600). IF RECEIVING A NEGATIVE ACKNOWLEDGEMENT OR NO RESPONSE, THE WTRU (500) RETRANSMITS THE PREAMBLE. (THE MOST ILLUSTRATIVE DRAWING IS

Abstract: IN A WIRELESS COMMUNICATION SYSTEM (100) COMPRISING AT LEAST ONE EVOLVED NODE-B (eNB) AND A PLURALITY OF WIRELESS TRANSMIT/RECEIVE UNITS (WTRUs) (120), A NON-CONTENTION BASED (NCB) CHANNEL IS ESTABLISHED, MAINTAINED, AND UTILIZED. THE NCB CHANNEL IS ALLOCATED FOR USE BY ONE OR MORE WTRUs IN THE SYSTEM FOR UTILIZATION IN A VARIETY OF FUNCTIONS, AND THE ALLOCATION IS COMMUNICATED TO THE WTRUs (120). THE WIRELESS COMMUNICATION SYSTEM (100) ANALYZES THE ALLOCATION OF THE NCB CHANNEL AS REQUIRED, AND THE NCB CHANNEL IS REALLOCATED AS REQUIRED.

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: Se proporciona un metodo y aparato que utiliza algoritmos que permiten a las redes celulares determinar el alcance de la energia de transmision de codigo en el control de energia de un enlace descendente, asi como un enlace ascendente. Dos algoritmos ejemplares proporcionan una determinacion de un alcance de energia de transmision apropiado para cada codigo de manera que cuando la energia de transmision de cualquier codigo se aproxima a un limite superior, la energia de transmision de los otros codigos se puede ajustar para que coincidan con el alcance dinamico. Aunque los dos algoritmos ejemplares tienen similitudes funcionales, en el segundo algoritmo la frecuencia de reconfiguracion del alcance de energia de transmision de codigo es mucho menor que la frecuencia de cambio del numero de codigos. Ambos algoritmos son aplicables para uso en todos los modos de transmision en sistemas UMTS.
