Abstract:
A method for transmitting signals to a user equipment at a base station in a wireless communication system is disclosed. The method includes generating a user equipment specific reference signal sequence for the user equipment, determining transmission resources for mapping the user equipment specific reference signal sequence, based on a vertical sector in which the user equipment is located, mapping the user equipment specific reference signal sequence to the determined transmission resources, and transmitting the user equipment specific reference signal sequence to the user equipment using a second-dimensional planar antenna.
Abstract:
The present invention relates to a method for transceiving a signal in a wireless communication system. A method for transceiving a signal in a wireless communication system according to one embodiment of the present invention comprises the steps of: deducing a channel from a transmission antenna of a transceiver; generating a reference signal by combining the deduced channel and a transmission signal from the transmission antenna; converting the reference signal into an analog signal; receiving a data signal and a self-interference signal by means of a reception antenna of the transceiver; and canceling the self-interference signal from the received data signal by means of the converted reference signal, wherein deducing a channel and combining signals are performed in the digital domain and discarding the self-interference signal is performed in the analog domain.
Abstract:
A method for transmitting a reference signal to a user equipment at a base station in a wireless communication system is disclosed. The method includes transmitting the reference signal to the user equipment according to a first pattern corresponding to a first rank and, if a rank is changed from the first rank to a second rank, transmitting the reference signal to the user equipment according to a second pattern corresponding to the second rank, wherein, if the second rank is greater than the first rank, the second pattern includes the first pattern. Preferably, the first pattern is a reference signal pattern for a single rank and the second pattern is defined as a hierarchical structure in which one or more reference signal symbols are added to the first pattern in a time domain direction.
Abstract:
A method is described for receiving a downlink control information (DCI) from a base station (BS) by a user equipment (UE) in a wireless communication system. The method includes monitoring a plurality of physical downlink control channel (PDCCH) candidates having the same payload size in a common search space and a UE-specific search space on a primary cell to receive the DCI. The common search space and the UE-specific search space are overlapped. If the UE is configured with a carrier indicator field (CIF), the method further includes determining that only a PDCCH in the common search space is transmitted from among the plurality of PDCCH candidates.
