  • Patent number: 10412720
    Abstract: A method is provided for monitoring a control channel in a wireless communication system. A wireless device receives information from a base station for a search space in which a downlink control channel is monitored. The received information further includes first information indicating either a localized transmission or distributed transmission. The wireless device monitors the downlink control channel in the search space of a subframe, in at least one enhanced control channel element (ECCE) including a plurality of enhanced resource element groups (EREGs). If the first information indicates the localized transmission, the plurality of EREGs in each of the at least one ECCE are mapped to one of a plurality of physical resource block (PRB) pairs. If the localized transmission is used, the plurality of EREGs are associated with a single antenna port selected based on an index of the at least one ECCE and the wireless device's specific information.

  • Patent number: 10313092
    Abstract: A method and wireless station for receiving signals. The wireless station receives, from a base station, a control signal on a first subframe indicated as a downlink (DL) subframe by a time division duplex (TDD) uplink-downlink (UL-DL) subframe configuration. The control signal includes first information indicating that at least one UL subframe indicated by the TDD UL-DL subframe configuration is reconfigured as a TDD DL subframe. The wireless station receives, from the base station, DL data on a second subframe which was indicated as a TDD UL subframe by the TDD UL-DL subframe configuration but is currently reconfigured as a TDD DL subframe by the control signal. The wireless station transmits, to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the control signal.

  • Patent number: 10306619
    Abstract: A method is provided for receiving a downlink signal at a downlink reception entity in a wireless communication system. Downlink control information is received by demodulating a Physical Downlink Control Channel (PDCCH) in a first resource block (RB) pair within an RB bundle by using a first Demodulation Reference Signal (DMRS). Downlink data is received by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs scheduled by the downlink control information within the RB bundle by using a second DMRS based on an assumption that a same precoder is applied to the scheduled one or more second RB pairs.

  • Patent number: 9979513
    Abstract: A method is provided for performing a hybrid automatic repeat request (HARQ) by a user equipment (UE). An uplink (UL) grant for a first subframe of a second serving cell is received through a first serving cell. UL data in the first subframe of the second serving cell is transmitted according to the UL grant. When a not-acknowledgement (NACK) for the UL data is received through a physical HARQ indicator channel (PHICH) in a subframe i of the first serving cell, the UE performs a non-adaptive retransmission for the UL data in a second subframe of the second serving cell. When a PHICH resource corresponding to the UL data is not present in the subframe i, the UE does not perform the non-adaptive retransmission in the second subframe of the second serving cell.
