Abstract: A method and system for resource allocation is provided. A method includes identifying bit map information on a set of resource blocks associated with a control channel for a UE, through radio resource control (RRC) signaling from a base station; receiving, from the base station, control information for downlink data on the control channel identified based on the bit map information; and receiving, from the base station, the downlink data on a data channel based on the control information. The control information is received on at least one control channel resource, which is included in the set of resource blocks. A search space for the control channel of the UE is defined based on an aggregation level, a number of the at least one control channel resource included in the set of resource blocks, and a number of a candidate associated with the control channel.

Abstract: A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.
