Abstract: A method and wireless transmit/receive unit (WTRU) for uplink transmission are disclosed. A WTRU receives configuration information. The configuration information includes logical channel priority information and a maximum number of hybrid automatic repeat request (HARQ) transmissions. For a transmission time interval (TTI), the WTRU identifies a HARQ process to use for uplink transmission for the TTI on a condition that an uplink grant is for the TTI. The WTRU selects data for uplink transmission for the TTI. For a new uplink transmission, data is allocated in decreasing order of priority based on the logical channel priority information. The WTRU initializes a transmission counter. The transmission counter indicates a number of transmissions associated with the selected data. The WTRU transmits the selected data over an uplink channel based on the uplink grant using the identified HARQ process.

Abstract: A method and apparatus for synchronization in an orthogonal frequency division multiplexing (OFDM) network is disclosed. A wireless transmit/receive unit (WTRU) is configured to receive a primary synchronization signal and a secondary synchronization signal from a cell. The primary synchronization signal and the secondary synchronization signal are spaced by a known number of OFDM symbols. The primary synchronization signal and the secondary synchronization signal are received in a same number of subcarriers in their respective OFDM symbol. A location of at least the secondary synchronization signal in the system bandwidth is variable.

Abstract: A user equipment (UE) may detect a primary synchronization signal and a secondary synchronization signal. The secondary synchronization signal may be derived from a shift of a sequence and sectors and cells may have different shifts of the sequence. A UE may determine, based on the detected primary synchronization signal and the secondary synchronization signal, an identity of a cell.

Abstract: In a wireless communication system including a wireless transmit/receive unit (WTRU) and at least one Node-B, a method and apparatus is used to selectively enable reception of at least one downlink (DL) enhanced uplink (EU) signaling channel established between the WTRU and the Node-B(s). During the operation of an enhanced dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the Node-B(s) only when it is necessary, based on the WTRU's knowledge of at least one established standard procedure. The WTRU coordinates and consolidates DL signaling channel reception requirements of a plurality of channel allocation and/or data transmission procedures carried out by the WTRU in accordance with the established standard procedure. The WTRU determines whether to enable reception of at least one specific DL signaling channel based on the consolidated DL signaling channel reception requirements.

Abstract: A radio access network comprises a serving radio network controller (S-RNC). The S-RNC receives successfully received medium access control (MAC) packet data units (PDUs), discards duplicates of MAC PDUs, reorders the non-discarded MAC PDUs based on serial numbers of the MAC PDUs and delivers the MAC PDUs to a radio link control protocol layer. A controlling radio network controller (C-RNC) provides information to Node-Bs under its control for use in scheduling uplink transmissions. A plurality of Node-Bs schedule uplink transmissions in response to the information provided by its C-RNC, transmit scheduling information to user equipments of its cells, receive MAC PDUs from user equipments of its cells using hybrid automatic repeat request and forward the successfully received MAC PDUs to an associated S-RNC.

Abstract: A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.
