  • Patent number: 10305715
    Abstract: A method is provided for receiving a downlink control channel in a wireless communication system. A user equipment performs a blind decoding in a first search space on the cell to find a first Physical Downlink Control Channel (PDCCH). The user equipment receives a Radio Resource Control (RRC) message including information on a second search space for monitoring a second PDCCH and identity information, and performs a blind decoding in the second search space on the cell to find the second PDCCH. The first PDCCH is demodulated based on a physical cell identity of the cell, and the second PDCCH is demodulated based on the identity information instead of the physical cell identity.

  • Patent number: RE48223
    Abstract: According to one aspect of the present invention, values which are specifically defined for each user equipment are reflected when resource allocation/mapping of downlink/uplink ACK/NACK channels is performed, so as to vary uplink/downlink ACK/NACK information transmitting resources for each user equipment allocated to the same downlink/uplink resource. According to another aspect of the present invention, nodes for transmitting uplink/downlink ACK/NACK information vary for each user equipment allocated to the same downlink/uplink resource. According to the present invention, even when downlink/uplink signals for a plurality of user equipment are transmitted from the same resource, uplink/downlink ACK/NACK signals of the plurality of user equipment are transmitted from different resources, thereby reducing interferences among ACK/NACK signals of the plurality of user equipment.
