Abstract: An apparatus and method for radio link monitoring in a wireless communication system are provided, in which a transmission point communicating with a network where a Base Station (BS) and at least one Remote Radio Head (RRH) coexist within a cell receives Reference Signal Configuration Information (RSCI) from the network to which the transmission point belongs, receives RSs of at least one RS type indicated by the received RSCI from the BS and the at least one RRH that coexist within the cell, and performs radio link monitoring using the received RSs of the at least one RS type.

Abstract: Methods and apparatuses for transmitting and receiving at least one Downlink Control Information (DCI) in a communication system supporting Carrier Aggregation (CA) are provided. The method for receiving includes receiving information representative of presence of carrier indicator by higher layer signaling from a Node B; receiving information representative of at least one cell indicator by higher layer signaling from the Node B; defining an UE specific search space based on aggregation level, an UE ID, and at least one carrier indicator value, where the UE specific search space includes a set of Physical Downlink Control CHannel (PDCCH) candidates based on the aggregation level; decoding at least one PDCCH including at least one DCI respectively by the UE ID; and acquiring the at least one DCI, wherein the at least one carrier indicator value is based on the at least one cell indicator.

Abstract: Methods and apparatuses are provided for transmitting and receiving a signal using a sequence in a wireless communication system. The method includes receiving, from a base station, information indicating whether sequence hopping is applied or not; transmitting, to the base station, the signal using a first sequence if a number of resource blocks allocated to the user equipment is less than a predetermined value; and transmitting, to the base station, the signal using a second sequence to which the sequence hopping is applied based on the received information if the number of the resource blocks allocated to the user equipment is greater than or equal to the predetermined value. The sequence hopping is performed using a pseudo-random function, and the sequence hopping is performed in a unit of a slot.

Abstract: Methods and apparatus are provided in which data is received from a base station on a downlink data channel. It is determined whether a scheduling type of the downlink data channel is persistent or non-persistent. Acknowledgement/negative acknowledgement (ACK/NACK) information for the data is transmitted to the base station. In case that the scheduling type is non-persistent, the ACK/NACK information is transmitted on a first resource determined according to a downlink control channel corresponding to the data. In case that the scheduling type is persistent, the ACK/NACK information for an initial persistent data transmission is transmitted on a second resource determined by using resource information received by high-layer signaling, and the ACK/NACK information for a persistent data retransmission is transmitted on a third resource determined according to the downlink control channel associated with the persistent data retransmission.

Abstract: A method for transmitting uplink information by a user equipment in a wireless communication system, the user equipment, a method for receiving uplink information by a base station in a wireless communication system, and the base station are provided. The method for transmitting uplink information by a user equipment in a wireless communication system includes mapping a reference signal on a first symbol in a slot; mapping acknowledgement information in response to reception of downlink data on a second symbol placed directly after the first symbol in the slot; and transmitting a signal including mapped data of the reference signal and the acknowledgement information in the slot.

Abstract: A method and apparatus are provided for transmitting and receiving control information in a wireless communication system. A method in a base station includes identifying an offset value and a number of control channel candidates corresponding to a number of control channel elements (CCEs) constituting one control channel candidate; determining indexes of control channel candidates based on the identified offset value and the identified number of control channel candidates; and transmitting the control information to the terminal through at least one of the control channel candidates in a downlink control channel. The determined indexes of control channel candidates are spaced by a value determined based on the transmitted number of control channel candidates.

Abstract: An apparatus and a method for transmitting/receiving downlink data channel signal transmission information in a cellular radio communication system using a Cooperative Multi-Point (CoMP) scheme are provided. In the downlink data channel signal transmission information transmission method, a Base Station (BS) transmits downlink data channel signal transmission information including information related to Resource Elements (REs) scheduled for a downlink data channel signal transmission to a User Equipment (UE), and transmits downlink data channel signal non-transmission information including information related to REs through which a downlink data channel signal is not transmitted among the REs scheduled for the downlink data channel signal transmission to the UE.
