Abstract: The present application provides methods for controlling a small cell on or off procedure in a Small cell specific Gate Way (S-GW). One of the methods comprises steps of receiving a cell indication message from a Source Small Cell (SSC), the cell indication message includes a cell state change indication parameter indicating whether the SSC is to be on or off and a cell on/off timer parameter indicating a time duration for a cell on process or a cell off process; transmitting request message requesting to expand or shrink a cell coverage of a Target Small Cell (TSC) according to the cell state change indication parameter; and receiving a complete indication message indicating the cell on process or the cell off process is complete after the time duration indicated by the cell on/off timer parameter from the SSC.

Abstract: A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIS, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped.

Abstract: A method of supporting signal transmission/reception using at least two RATs and apparatus therefor are disclosed. The present invention includes, receiving, at the user equipment concurrently connected a first base station of a first communication network supportive of a first RAT and a second serving base station of a second communication network supportive of a second RAT, a setup message indicating a handover from the second serving base station to a second target base station from a first base station, terminating a connection to the second serving base station, and establishing a connection to the second target base station. Before the connection to the second serving base station is terminated, data for a specific traffic type is transceived via the second serving base station. After the connection to the second target base station is established, the data for the specific traffic type is transceived via the second target base station. Data except the specific traffic type is transceived via the first base station.

Abstract: A method and apparatus for transmitting a Reference Signal (RS) during retransmission at a User Equipment (UE) in a multi-antenna wireless communication system are disclosed. The RS transmission method includes receiving an uplink grant from a Base Station (BS), initially transmitting data and an RS corresponding to each layer based on the uplink grant, receiving ACKnowledgment/Negative ACKnowledgment (ACK/NACK) information for the initially transmitted data, and retransmitting the RS corresponding to each layer and the data according to the ACK/NACK information. The retransmission includes initializing a cyclic shift value for the RS corresponding to each layer according to a cyclic shift field for RSs included in the uplink grant.
