Abstract: A method and apparatus for allocating resource between uplink ACK/NACK channel and downlink control channel supporting spatial multiplexing in an OFDM-based wireless communication system which configures uplink ACK/NAK channel implicitly using reference signals for discriminating among resource allocation spaces and physical channel resource. The method is capable of multiplexing the uplink ACK/NACK channel associated with the control channel extended by spatial multiplexing into the uplink ACK/NACK channel resource which does not support spatial multiplexing.

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: A fractional Resource Block (RB) allocation method which enables resource allocation in a unit smaller than RB to improve the capacity of Voice over Internet Protocol (VoIP) in a Long Term Evolution (LTE) system is provided. The method includes generating modulation symbols streams by performing channel coding and modulation on transport blocks corresponding to first and second data to be transmitted to respective users, multiplexing the modulation symbols stream alternately in a unit of two continuous modulation symbols, and transmitting the multiplexed modulation symbol stream as mapped to corresponding resource. A resource arrangement method allows different users to share the same resource without using a Space Domain Multiple Access (SDMA) and indicates fractional RB allocation.
