Abstract: A wireless transmit/receive unit (WTRU) is configured to, on a condition that a serving grant having a non-zero value is too small for transmission of a single protocol data unit (PDU) from any scheduled medium access control-d (MAC-d) flow, transmit scheduling information (SI). The WTRU is further configured to produce a trigger on the condition that the serving grant is too small and the transmission of the SI is based on the produced trigger.

Abstract: A wireless transmit/receive unit (WTRU) may periodically transmit control information in slots. The control information may include channel quality indicators (CQIs) for a plurality of cells. In response to expiration of a timer for a first cell of the plurality of cells or in response to a received layer 2 (L2) message associated with the first cell, the transmission of the control information including the CQIs may be ceased for the first cell and the periodic transmission of the control information may continue for a second cell of the plurality of cells.

Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

Abstract: A method and apparatus for cell update while in a Cell_FACH state are disclosed. After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.

Abstract: A method and apparatus for requesting and releasing resources for a wireless transmit/receive unit (WTRU) and/or Node B. The WTRU may transmit a channel acquisition request to the Node B and receive a resource allocation from the Node B. The resource allocation may include a common resource. The WTRU may release the common resource. The release may be based on one or more conditions. The channel acquisition request or the resource allocation may include information related to one or more channels or resources.

Abstract: A wireless transmit/receive unit includes at least one processor that receives a high speed physical downlink shared channel, and in response, transmits at least one random access channel preamble followed by ACK/NACK and channel quality indicator (CQI) information. The at least one random access channel preamble is selected from a set of random access preambles reserved for the ACK/NACK and CQI information.
