Abstract

See full text

Embodiments of the invention provide methods for transmitting reference signals (RS) from user equipments (UEs) in wireless communication systems. These RS are used, among other functions, by a serving base station to schedule data transmission from UEs and perform power and timing control of the UE signal transmissions. The RS are constructed based on constant amplitude zero autocorrelation (CAZAC) sequences, including their possible modifications. The invention describes methods to multiplex transmission of RS from multiple UEs by having the serving base station control the CAZAC sequence and the associated cyclic shift, transmission bandwidth, transmission period, and transmission power applied to the RS transmission by each UE.
