  • Publication number: 20220141843
    Abstract: Aspects of this disclosure relate to forming clusters of user equipments and network nodes. A first cluster of first user equipments and first network nodes in a first section can be formed for a time slot. A second cluster of second user equipments and second network nodes in a second section can be formed for the time slot such that the first user equipments are protected from interference associated with the second cluster. During the time slot, the first section has higher priority than the second section. Multiple-input multiple-output wireless communications can occur during the time slot (a) from the first network nodes to the first user equipments and (b) from the second network nodes to the second user equipments.

  • Publication number: 20210314962
    Abstract: A first radio device may send SL control information to a second radio device. The SL control information indicates at least one radio resource for transmission of a reference signal from the first radio device. The second radio device receives the reference signal. Further, the second radio device may forward the received sidelink control information to one or more other radio devices. Based on the received reference signal, the second radio device estimates quality of a radio channel between the first radio device and the second radio device. The estimated quality of the radio channel, may be used to control an SL radio transmission between the first radio device and the second radio device.
