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 measurement reporting and event-triggered periodic measurement reporting in an evolved universal terrestrial radio access network (E-UTRAN) are disclosed. A wireless transmit/receive unit (WTRU) monitors cell-specific reference signals from a serving cell and neighbor cells to detect a reporting event defined for the E-UTRAN. Once a reporting event is detected, the WTRU sends a measurement report to the network. The measurement quantity may be a reference signal received quality (RSRQ). After detection of the reporting event, the WTRU may send event-triggered measurement reports periodically. The WTRU may send a scheduling request to the network for the event-triggered periodic measurement reports. The WTRU may send a termination indication if the event-triggered periodic measurement reports are terminated before a configured number of times. The WTRU may send an extension request if a specified number of periodic reporting has been sent but more reports still need to be sent.

An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.
