無線通信システム内の端末装置のページングのための方法および装置

Document Type and Number:

Japanese Patent JP2009544244

Kind Code:

A

Abstract:

Techniques for paging terminals in a wireless (e.g., OFDMA) communication system to achieve both fast paging response and low power consumption for the terminals are described. A terminal receives paging indicator from a base station. If the paging indicator indicates that the terminal is potentially being paged, then the terminal receives at least one paging message from a paging channel. The terminal determines whether any one of the at least one paging message is for the terminal e.g., based on identification information included in each paging message. If a paging message indicates that the terminal is paged, then the terminal sends an acknowledgement for the paging message. The base station may estimate the timing of the terminal based on the acknowledgement and may send timing adjustment to the terminal. The terminal may adjust its timing based on the timing adjustment and may be able to quickly access the system with no contention.
