  • Patent number: 11902931
    Abstract: Methods and apparatus for transmitting positioning measurement report are provided. The method includes a step of receiving a location information request from a serving base station or from a location server, a step of determining timing for transmitting a positioning measurement report, a step of generating a report assisted message based on the determined timing for transmitting the positioning measurement report, and a step of transmitting the report assisted message to the serving base station. The key idea of this disclosure is requesting UL resources for positioning measurement report in advance by transmitting a report assisted message. Consequently, the UE can transmit the positioning measurement report just after the measurement data being generated. The disclosure can minimize the delay from positioning measurement data generation to the positioning measurement report.

  • Publication number: 20230379123
    Abstract: A method performed by a User Equipment (UE) for handling a Control Resource Set (CORESET) from a network node in a wireless communications network is provided. The UE operates with a reduced bandwidth. The UE detects a CORESET from the network node, and that a bandwidth of the CORESET is larger than the bandwidth of the UE. Physical Downlink Control Channel (PDCCH) candidates are transmitted in the CORESET. The UE determines which part of the CORESET to skip, to make the bandwidth of the CORESET equal or smaller than the bandwidth of the UE, such that the UE is capable of receiving the CORESET. The part of the CORESET to be skipped is determined based on a predicted decoding performance of the PDCCH candidates in the CORESET.

  • Patent number: 10536194
    Abstract: The present invention is related to an apparatus and method for signaling information exchanging in CoMP (Coordinated Multi-Point). According to an embodiment of the present invention, in a method for signaling information exchanging, a service TP (Transmission Point) and at least one neighboring TP provide the CoMP to at least one UE (User Equipment). The method comprises receiving by the service TP a precoder feedback from at least one UE, wherein the precoder is specific to one of the least one neighboring TP. The service TP decides if the precoder should be sent to the specific neighboring TP. If affirmative, the service TP compresses an indicator indicating the precoder and sends the compressed indicator to the specific neighboring TP.
