  • Patent number: 10694575
    Abstract: A method may be provided to operate a user equipment device, UE. The method may comprise, when operating with a short Transmission Time Interval (sTTI), and when using connected mode discontinuous reception, DRX, monitoring transmissions from a radio access network node during a first part of a subframe for a UE-specific message for the UE containing first control information. If no UE-specific message for the UE containing first control information is received, the UE may be inactive during a second part of the subframe following after the first part of the subframe. If the UE receives the UE-specific message containing first control information, it may monitor the second part of the subframe for a message containing second control information, for use in receiving or transmitting data from or to the radio access network node.

  • Patent number: 10674531
    Abstract: Systems and methods for collision handling between transmissions using a first Transmission Time Interval (TTI) and transmissions using a second TTI, such as a legacy TTI and a short TTI (sTTI), are provided. In some embodiments, the proposed solution helps the UE handle collisions between transmissions using legacy TTI in UL and overlapping transmissions using short TTI in UL. In some embodiments, this is accomplished by a wireless device adapted for uplink transmissions using a first TTI or a second TTI where the second TTI is shorter than the first TTI. The method includes altering at least one transmission of a first transmission using the first TTI and a second transmission using the second TTI based on a determination that a collision is to occur between the first transmission and the second transmission.

  • Publication number: 20200067647
    Abstract: A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

  • Publication number: 20200052812
    Abstract: A method performed by a network node for handling a damaged transmission of data due to data puncturing is provided. The network node receives (201), from a User Equipment, (UE) a Negative Acknowledgment (NACK) feedback of a previous transmission of data transmitted to the UE. The network node checks (202) whether or not the data is punctured in the previous transmission corresponding to the NACK feedback. When the data is punctured in the previous transmission, the network node selects (203) a Redundancy Version (RV), for a retransmission of the data, according to characteristics of the punctured data and puncturing data. The network node then sends (204) a Puncturing Indication (PI), the selected RV and the retransmission of the data to the UE.
