Abstract:
PURPOSE: A control/data multiplexing method in an uplink multiple-input multiple-output (MIMO) system based on single-carrier frequency division multiplexing (SC-FDM) and a device thereof are provided to multiplex hybrid automatic-repeat-request acknowledgment information (HARQ-ACK) or rank indication (RI) resource elements along with multiple data resource elements in a physical uplink shared channel (PUSCH). CONSTITUTION: When a payload is within a second range, a mobile station determines a minimum number of resource elements to be used for HARQ-ACK or RI according to a second mathematical equation. The mobile station determines the number of resource elements according to the minimum number and a third mathematical equation. The mobile station allocates the determined number of resource elements to HARQ-ACK or RI. The mobile station multiplexes the HARQ-ACK or RI resource elements along with multiple data resource elements in a PUSCH.

Abstract:
PURPOSE: A method and system capable of transmitting an uplink acknowledge signal in carrier aggregation wireless communication systems are provided to transmit ACK/NACK using channel selection having two uplink transmission antenna ports and PUCCH format 1B. CONSTITUTION: DL transmission for a UE(410) is scheduled by an eNodeB(420). The eNodeB transmits DL control information to a UE in a physical DL control channel(PDCCH) located in a first couple of OFDM symbols of a sub frame(401). A DCI indicates RBs and the other information assigned for a UE. The eNodeB transmits a message to a UE(403). The UE performs attempt for decoding of transmitted message in the assigned RBs. The UE transmits hybrid automatic repeat request bits in a sub frame to the eNodeB.

Abstract:
A method for enabling interference coordination for use in a heterogeneous network includes determining whether a first low power node approaches a second low power node at the first low power node if a trigger condition occurs. The method also includes transmitting an entering message from the first low power node to a base station (evolved Node-B, eNB) which serves the first low power node. Moreover, the method includes receiving configuration information from the base station at the first low power node in order to perform at least one measurement of the second low power node.

Abstract:
PURPOSE: A method and system for mapping an uplink control data are provided to simultaneously transmits channel quality information, rank information, and ACK/NACK information. CONSTITUTION: A base station transmits an uplink authentication, which orders a first coding method value for transmitting a first code word, and a second MCS value for transmitting a second code word, to a subscriber terminal (801). The base station receives sub-frame of multiple output uplink from the terminal of a subscriber (803). The sub-frame of multiple output uplink has a sub assembly of first layers and a sub assembly of second layers. Information about ACK/NACK and rank-indicating information are mapped with the sub assembly of first layers and the sub assembly of second layers. Information about channel quality is mapped with the sub assembly of first layers and the sub assembly of second layers.
