    摘要: The present invention relates to a wireless communication system. In particular, the present invention relates to a method and an apparatus for transmitting uplink control information, including the steps of: generating a plurality of HRAQ-ACKs (Hybrid ARQ Acknowledgements), selecting one or more PUCCH (Physical Uplink Control Channel) resource indexes corresponding to the HARQ-ACKs from a plurality of PUCCH resource indexes, and transmitting one or more modulation symbols corresponding to the plurality of HARQ-ACKs using resources corresponding to the one or more PUCCH resource indexes, in which, when a number of the plurality of HARQ-ACKs is two, the one or more modulation symbols are transmitted only in a first multiple antenna transmission manner, and when a number of the plurality of HARQ-ACKs is three or more, the one or more modulation symbols are transmitted in any one of a plurality of second multiple antenna transmission manners.

    摘要: Disclosed are a method for transmitting and receiving a UE-specific reference signal and an apparatus for same. A method for a base station transmitting the UE-specific reference signal in a wireless communication system, according to one embodiment of the present invention, comprises a step of the base station transmitting the UE-specific reference signal to the UE by using a pre-determined pattern, wherein the predetermined pattern can be a pattern which is mapped onto an RE, in which the UE-specific reference index is an index including symbol indexes 0, 3 and 6 from an even-numbered index slot within one resource block (RB), or mapped onto an RE in which the UE-specific reference index is an index including symbol indexes 2 and 5 from an odd-numbered index slot within the RB.

    摘要: An eNodeB (eNB), user equipment (UE) and method for operating using a reduced data transmission bandwidth are generally described. The UE may receive downlink control information (DCI) that provides a resource allocation (RA) of a reduced physical resource block (PRBmin) of less than 1 PRB for communications in a PRB of a subframe. Whether the RA is localized or distributed may be predefined, configured via system information block or Radio Resource Control signaling, or indicated in the DCI format. The DCI format may specify the resources within the PRB allocated to the UE through a subcarrier block index and total number of subcarrier blocks or a bitmap corresponding to a unique block of subcarriers or block index. An order in a list of cell Radio Network Temporary Identifiers (RNTIs) may be used with a common RNTI to derive the reduced RA from a 1 PRB RA.
