  • Publication number: 20230318689
    Abstract: Disclosed are an information indication method, a node and a storage medium. The information indication method includes: by a first communication node, generating a control command, and then transmitting the control command to a second communication node, wherein the control command carries control information or carries control information and pre-compensation parameter information. The pre-compensation parameter information is used to indicate a first parameter. The control information is used to indicate whether the first communication node performs pre-compensation for the first parameter of at least one of a PDCCH, a PDSCH and a CSI-RS according to a configured QCL relationship.

  • Publication number: 20220210761
    Abstract: Provided are a method and an apparatus for implementing uplink positioning and a storage medium. The method includes: sending a first positioning instruction to a first measurement node set, where the first measurement node set includes at least three measurement nodes and a target node is located within a coverage range of the measurement nodes; receiving first positioning attribute information fed back by each measurement node and corresponding to the first positioning instruction, where the first positioning attribute information includes a measurement node identity and random access information of a cell where the measurement node is located; and sending a random access instruction carrying the first positioning attribute information to the target node, where the random access instruction is configured to trigger the target node to send a random access signal to the each measurement node to determine a communication distance between the target node and the each measurement node.
