MULTIPLE-INPUT MULTIPLE-OUTPUT FEEDBACK INFORMATION TRANSMISSION AND RECEPTION METHOD IN A WIDEBAND WIRELESS COMMUNICATION SYSTEM AND BASE STATION THEREOF CAPABLE OF REDUCING THE OVERHEAD OF UNNECESSARY DOWNLINK CONTROL INFORMATION

摘要

PURPOSE: An MIMO(Multiple-Input Multiple-Output) feedback information transmission and reception method in a wideband wireless communication system and base station are provided to enable an M2M apparatus to rapidly enter into a network according to a network entering method.;CONSTITUTION: When a corresponding terminal is a fixed M2M apparatus, a base station adds an MIMO feedback information to a ranging request message(S302). The base station transmits the ranging request message to the terminal(S303). The terminal receives a ranging response message from the base station. The terminal executes a remaining network entering process or a remaining re-entering network process(S305). When the terminal is not the fixed M2M apparatus, the terminal executes the existed normal network entering process or the existed normal re-entering process(S304).;COPYRIGHT KIPO 2013;[Reference numerals] (S301) Starting network entering procedure; (S302) When a corresponding terminal is a fixed M2M apparatus, a base station adds an MIMO feedback information to a ranging request message; (S303) The base station transmits the ranging request message to the terminal; (S304) When the terminal is not the fixed M2M apparatus, the terminal executes the existed normal network entering process or the existed normal re-entering process; (S305) The terminal executes a remaining network entering process or a remaining re-entering network process
