Abstract: Systems, methods, and instrumentalities for a WTRU to perform channel estimation and/or noise estimation are provided. The techniques described herein may be used to perform channel estimation and/or noise estimation that meet certain performance and latency goals while utilizing a lower cost design than previous channel/noise estimation techniques. For example, the channel estimation/noise estimation techniques described herein may be implemented using less memory (e.g., less memory for storing filter coefficients) while still achieving the desired latency and performance goals. The techniques described herein may be implemented by any WTRU and/or by a WTRU specifically designed to be low-cost.

Abstract: A method and apparatus for use in connection with wireless communication to adjust the frequency of an oscillator to synchronize with a received signal by correlating a synchronization code channel with training sequences to estimate relative offsets which are employed to estimate an error, which is then filtered. The filtered output preferably provides a voltage controlling a voltage controlled oscillator (VCO). The same technique may be employed to control a numeric controlled oscillator (NCO).
