Abstract: The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for transmitting or receiving a downlink signal considering an antenna port relationship. The method for enabling a terminal to receive a physical downlink sharing channel (PDSCH) signal in the wireless communication system according to one embodiment of the present invention can determine a PDSCH start symbol index according to the predetermined priority and receive the PDSCH signal therethrough. The PDSCH start symbol index can be determined when a PDSCH start symbol value included in a PDSCH resource element mapping and Quasi co-location Indicator (PQI) parameter set is determined by an upper layer. The PDSCH start symbol index can be determined according to the PDSCH start symbol value for a cell receiving the PDSCH when the PDSCH start symbol value included in the PQI parameter set is not determined by the upper layer.

Abstract: The present invention relates to a wireless communication system. A method for receiving data by a user equipment (UE) in a cooperative multi-point (CoMP) wireless communication system includes receiving information indicating a transmission base station (BS) that actually transmits data among a plurality of BSs that participate in CoMP, receiving information about zero-power channel state information-reference signal (CSI-RS) of each of the plural BSs, and assuming that data is not mapped to a resource element of zero-power CSI-RS corresponding to the transmission BS and receiving the data through a physical downlink control channel (PDSCH).

Abstract: A method and a device for transmitting reference signals in a wireless communication system are disclosed. For these, a sequence is acquired to be used for the reference signals, and the reference signals are transmitted through subframes comprising a first type subframe and a second type subframe. Here, the first type subframe includes a first number of OFDM symbols and the second type subframe includes a second number of OFDM symbols. And, a first position of OFDM symbol for transmitting the reference signals at the first type subframe is the same as a second position of OFDM symbol for transmitting the reference signals at the second type subframe.

Abstract: A method for receiving operating class information by a station (STA) from an access point (AP). A frame including a country element is received by the STA. The country element includes one or more operating/subband sequences having an operating triplet. The operating triplet includes an operating extension identifier field, an operating class field and a coverage class field. If a predetermined condition is met, the STA identifies that information on the country element is for two frequency segments having an equal width. The predetermined condition is that the received frame comprises two consecutive operating/subband sequences having first and second operating triplets. The first operating triplet indicates a specific behavior mode and the second operating triplet indicates a behavior mode other than the specific behavior mode. If the predetermined condition is not met, the STA identifies that the information on the country element is for one frequency segment.
