  • Patent number: 10567135
    Abstract: A method performed by a network node (110) for deciding a feedback option of a message sent between the network node (110) and a User Equipment, UE, 120 in a wireless communication network (100) is provided. The message comprises a first data, which is punctured by a second data. The first data is sent in a slot of a radio resource. The second data is sent a mini-slot of the radio resource. The mini-slot is smaller than the slot. The network node (110) decides (401) a feedback option for feedback that is to be sent to the sender of the message. The deciding is based on any one or more out of: slot control resource capacity, mini-slot control resource capacity and requirements of the radio bearer.

  • Patent number: 10560949
    Abstract: A second communication device transmits information relating to a request for a first set of radio resources of a radio channel for a first data transmission to a third communication device. This information is received by a first communication device. In response thereto, the first communication device transmits an interference notification to the second communication device when the received information relating to a request for radio resources of the radio channel is determined to conflict with requested radio resources of the radio channel for a second data transmission to or from the first communication device. The second communication device receives an interference notification from the first communication device indicating that its transmitted information relating to a request for radio resources of the radio channel has been determined to conflict with requested radio resources of the radio channel for the second data transmission to or from the first communication device.

  • Publication number: 20200015122
    Abstract: Different Transmission Block Size (TBS)/Modulation and Coding Scheme (MCS) mapping tables, especially TBS/MCS mapping table sets, are used for Ultra-Reliable and Low-Latency Communications (URLLC) traffic and non-URLLC traffic. A TBS/MCS mapping table for URLLC is selected by a network node, upon determination of traffic type as URLLC, and informed to a UE. The informing can be a TBS/MCS mapping table index. After receiving the information of TBS/MCS mapping table selection, the UE identifies the selected TBS/MCS mapping table from its TBS/MCS mapping table set for URLLC.

  • Publication number: 20190384758
    Abstract: Scanning and rescanning detect state inconsistencies between data entities in repositories or other components of a distributed computing environment. First, entities are scanned based on a cutoff time TO. Entities for which state comparison is undesired are placed in a skipped entity list. Any inconsistencies found in other entities is reported. Then subsequent rescanning fetches state and attempts to pare down the skipped entity list. Rescanning may be capped. Inconsistencies may be detected without requiring downtime from services that update data entity state, and false reports of inconsistency may be avoided.

  • Publication number: 20190349136
    Abstract: A transmitting node can puncture bundles of data for a first service in a transmission for a second service. The first service has lower latency requirements than the second service. The transmitting node determines data for a first service will be transmitted during a time period when data for a second service will be transmitted, and determines transmission or reception conditions. Based on the determined transmission or reception conditions, the transmitting node determines to adjust the transmission of the first service. The transmitting node then transmits during the time period the data for the first service while data for the second service is transmitted during the time period, wherein the transmission includes an original set of data for the first service and at least one repetition of the original set of data for the first service.
