摘要： A method and apparatus for random access in an evolved universal terrestrial radio access (E-UTRA) system are disclosed. For code division multiplexing (CDM), a basic preamble is generated using a constant amplitude zero auto-correlation (CAZAC) sequence. The basic preamble is repeated for M time for generating a random access channel (RACH) preamble. For time division multiplexing/frequency division multiplexing (TDM/FDM), an extended CAZAC sequence is used to generate the basic preamble. Alternatively, a hybrid RACH access period including at least one CDM random access slot and at least one TDM/FDM random access slot may be provided. For synchronized random access, a RACH burst including a preamble part, a message part, and two cyclic prefixes may be generated and transmitted.

摘要： A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

摘要： A method and apparatus for mapping an uplink control channel to a physical channel in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A wireless transmit/receive unit (WTRU) generates control bits to be carried by a control channel. The WTRU maps the control channel to a plurality of subcarriers among subcarriers in a resource block assigned to the WTRU and to at least one long block (LB) in a sub-frame. The control channel includes a data-non-associated control channel and/or a data-associated control channel. The subcarriers mapped to the data-non-associated control channel may be distributed over all, or a fraction of, at least one resource block. The data-non-associated control channel may be mapped to the subcarriers with one or more subcarriers as a basic unit. The mapped subcarriers may be consecutive in frequency domain. The control bits may be multiplexed with data bits within the LB.

摘要： In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.

摘要： A method and apparatus for controlling uplink transmission power control of signals transmitted from a wireless transmit/receive unit (WTRU) to a serving base station in a packet-switched data based system having a plurality of neighbor cells. The path loss of neighbor interfering cells is measured by the WTRU and uplink interference measurements received from the neighbor interfering cells are monitored. The WTRU sends an uplink transmission request to the serving base station which includes a pilot signal and an uplink transmission power adjustment parameter computed by the WTRU. The serving base station performs a channel quality indicator (CQI) measurement of the pilot signal included in the uplink transmission request and determines the uplink transmission power of at least one of an uplink shared control channel and an uplink shared data channel established between the WTRU and the serving base station using the CQI and the uplink transmission power adjustment parameter.

摘要： A method and apparatus for inter-Node-B macro diversity in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A distributed subcarrier block including sufficient number of subcarriers to guarantee frequency diversity is allocated to a wireless transmit/receive unit (WTRU) for uplink transmission. The location of the subcarriers is fixed. The information regarding the assigned distributed subcarrier block is sent to Node-Bs in an active set of the WTRU and the Node-Bs receive and decode uplink transmission based on the information. Alternatively, a subcarrier block (either a distributed subcarrier block or a localized subcarrier block) and a starting seed in a frequency and time hopping sequence is allocated to a WTRU for uplink transmission. The information regarding the assigned subcarrier block and the starting seed is sent to Node-Bs in an active set of the WTRU and the Node-Bs receive and decode uplink transmission based on the information.

摘要： Urgent data is scheduled in a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B. The WTRU includes a re-ordering release timer. The Node-B includes a buffer, a lifespan (or maximum allowed delay) timer and a high speed downlink packet access (HSDPA) scheduler. The HSDPA scheduler determines whether there is at least one protocol data unit (PDU) in the buffer whose lifespan (maximum allowed delay) timer or re-ordering release timer will expire if the PDU is not transmitted in a next N transmission timing interval (TTI), where N is a design parameter. If so, the PDU is treated as urgent data whereby a sequence of WTRUs , (i.e., users), scheduled to receive urgent data is arranged in an order of decreasing priority, and a more conservative modulation and coding scheme (MCS), multiple code transmission and a different redundancy reversion are considered for use.
