METHOD AND APPARATUS FOR WIRELESS TRANSMIT/RECEIVE UNIT SPECIFIC PILOT SIGNAL TRANSMISSION AND WIRELESS TRANSMIT/RECEIVE UNIT SPECIFIC PILOT SIGNAL POWER BOOSTING FOR ENHANCING CHANNEL ESTIMATION

摘要

A method and apparatus are described for providing improved channel estimation for wireless transmit/receive units (WTRUs) that require improved channel estimation (e.g., cell edge WTRUs) by allocating additional resource elements (REs) as pilot signals to improve channel estimation. These additional REs may be allocated to be used with expanded reference signals (ERSs).
