Abstract: The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.

Abstract: Disclosed is a sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. The sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. In this environment, the sounding reference signal is transmitted through an antenna pattern through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead.

Abstract: A method and an apparatus are provided for transmitting and receiving uplink data in a wireless communication system. The method includes transmitting an uplink grant including resource allocation information and frequency hopping information; determining a resource for the uplink data based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled; and receiving the uplink data mapped on the determined resource. Mirroring is alternatively applied for determining the resource based on the packet transmission number.
