  • Patent number: 10484983
    Abstract: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

  • Patent number: 10374774
    Abstract: A downlink data transmission is performed in a downlink subframe. One or more resources are determined. The one or more resources are to be used for transmission or reception of error information for the received transmission in an uplink subframe based at least on an association set between one or more downlink or special subframes and an uplink subframe. The determined association set depends on a downlink reference configuration. The association set for each uplink subframe comprises a grouping of the downlink or special subframes into at least two groups. An association set is defined only for the subframes which are uplink subframes in a corresponding downlink reference configuration. The error information is transmitted or received using the determined one or more resources in the uplink subframe. Methods, apparatus, programs, and program products are disclosed.

  • Publication number: 20190200333
    Abstract: A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.
