  • METHOD AND DEVICE FOR SIDELINK DATA DUPLICATION
    Publication number: 20200403731
    Abstract: A method and device for sidelink data duplication. The method includes: determining whether a sidelink data packet is to be duplicated based on a sidelink radio bearer on which the sidelink data packet is to be transmitted; performing sidelink data duplication of the sidelink data packet when it is determined that the sidelink data packet is to be duplicated based on the sidelink radio bearer. Therefore, a solution provides for properly configuring data duplication for sidelink.

  • Methods, device and node for adapting a numerology depending on a position of a wireless device
    Patent number: 10869290
    Abstract: A method in a network node for adapting a numerology and slot structure depending on a position of a wireless device is provided. The position of the wireless device is measured by a timing advance (TA). For example, the method comprises: measuring a timing advance value for a User Equipment (UE); selecting a numerology and slot structure for UE data transmission based on the measured timing advance value; and sending an indication of the selected numerology and slot structure to the UE. A network node for carrying out this method is also provided.

  • Technique for Sidelink Feedback Transmissions
    Publication number: 20200305176
    Abstract: A technique for transmitting and receiving data (602) using a sidelink, SL, radio communication (604) between a first radio device (100) and a second radio device (200) is described. As to one method aspect of the technique, a scheduling assignment, SA (601), announcing a transmission of the data (602) for the second radio device (200) is broadcasted. The data is transmitted according to the SA (601) from the first radio device (100) in a unicast mode to the second radio device (200). Responsive to the data transmission, a control feedback (608) is received from the second radio device (200) in a unicast mode at the first radio device (100), wherein the control feedback (608) is received on a feedback radio resource (708) determined by at least one of the first radio device (100) and the second radio device (200).

  • SEMI-BLIND DETECTION OF URLLC IN PUNCTURED eMBB
    Publication number: 20200266922
    Abstract: The proposed embodiment provides an efficient way to implicitly detect at the receiver the puncturing information (i. e. time/frequency resources, MCS, TBS etc.) of the Ultra Reliable Low Latency Communication (URLLC) in the punctured Enhanced Mobile Broadband (eMBB) area. The performance of eMBB traffic can be improved by implicitly providing the puncturing information without any additional signaling or indications (e.g. does not require any additional bits).

  • Timing requirement dependent search space configuration for MTC devices of different categories
    Patent number: 10567130
    Abstract: An access node of the wireless communication network determines a configuration of a first search space (210) in terms of first time domain coordinates and first frequency domain coordinates of a time-frequency grid of radio resource elements. Further, the access node determines a configuration of a second search space (220) in terms of second time coordinates and second frequency domain coordinates of the time-frequency grid. The second search space (220) differs from the first search space at least with respect to the time domain coordinates. In radio resource elements of the first search space (210), the access node transmits downlink control information for a first class of radio devices subject to a first timing requirement. In radio resource elements of the second search space (220), the access node transmits downlink control information for a second class of radio devices subject to a second timing requirement which is stricter than the first timing requirement.
