Abstract: Methods and apparatuses are provided for a wireless communication system in which configuration information on a search space for monitoring a physical downlink control channel (PDCCH) is received from a base station. The configuration information includes information on a plurality of control resource sets (CORESETs) for the PDCCH. A PDCCH candidate set is identified for each of the plurality of CORESETs, based on the configuration information and an offset. The offset is used to adjust an index of a control channel element (CCE) in each PDCCH candidate set. The search space is determined based on the identified PDCCH candidate set for each of the plurality of CORESETs. The PDCCH is monitored based on the determined search space.

Abstract: The present invention relates to a method for transmitting, by a terminal, a sounding reference signal (SRS) or a physical uplink shared channel (PUSCH) in a mobile communication system. A communication method for a terminal in a communication system which supports the combination of configuration carrier using FDD scheme and configuration carrier using TDD scheme, in accordance with an embodiment of the present invention, comprises the steps of: receiving SRS transmission setting information from a base station; receiving uplink data scheduling information from the base station; determining whether or not the simultaneous transmission of the SRS transmission and the uplink data occurs; and setting the transmission of the uplink data or the SRS so that when the simultaneous transmission of the SRS transmission and the uplink data occurs, the sum of the respective transmission powers of the first and second symbols in an FDD cell and the first and second symbols of a TDD cell is not greater than the maximum transmission power of the terminal, wherein the timing of the first symbol in the FDD cell corresponds to the timing of the first symbol in the TDD cell, and the timing of the second symbol in the FDD cell corresponds to the timing of the second symbol in the TDD cell. In accordance with an embodiment of the present invention, defining the SRS transmission method of the terminal in a wireless communication system causes the terminal to effectively transmit the uplink data.

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.
