Abstract  Abstract

Disclose the method and apparatus transmitted for multiple transmission optimizations from the RACH (RACH) of wireless transmitter/receiver unit (WTRU).WTRU can use the time resource of configuration to initiate the ul transmissions for random access procedure, so that uplink resource can be shared by multiple WTRU times of carrying out.The transmission time can absolute or relatively on the basis of calculate.A Backoff time can be applied before starting ul transmissions.Described Backoff time can be that WTRU is specific, WTRU group is specific or each access category is specific, and can determine based on priority basis.Zoom factor may be used in described Backoff time.Contention-free distribution method can be used to determine suitable resource.Can with and transmit data without lead code.WTRU can include equipment for machine type communication, and can be grouped according to multiple factors or characteristic.
