  • Adaptive Sensing based Resource Selection for D2D Communication
    Publication number: 20230309065
    Abstract: A wireless communication device (10) configures a selection window and a sensing window. The selection window indicates radio resources allowed to be selected by the wireless communication device for a D2D transmission by the wireless communication device (10) and the sensing window indicates which radio resources are to be used for estimating an occupation status of the radio resources in the selection window. By monitoring the radio resources indicated by the sensing window, the wireless communication device (10) estimates the occupation status of the radio resources in the selection window. Based on the estimated occupation status of the radio resources in the selection window, the wireless communication device (10) selects radio resources from the selection window. Using the selected radio resources, the wireless communication device (10) performs at least one D2D transmission to at least one further wireless communication device (10).

  • CONFIGURING PUNCTURE BUNDLES OF DATA FOR A FIRST SERVICE IN A TRANSMISSION OF A SECOND SERVICE
    Publication number: 20230254064
    Abstract: A transmitting node determines data for a first service will be transmitted during a time period when data for a second service will be transmitted. The data for the first service requires lower latency than the data for the second service and the data for the first service includes an original set of data for the first service and at least one repetition of the original set of data for the first service. The transmitting node adjusts resources consumed by the data for the first service based on available transmission resources. During the time period the transmitting node then transmits the data for the first service using the adjusted resources while data for the second service is transmitted during the time period.

  • POWER CONTROL FOR BIDIRECTIONAL SIDELINK
    Publication number: 20220377674
    Abstract: Power control for a bidirectional Sidelink (SL) is provided. Solutions proposed herein limit the Physical SL Feedback Channel (PSFCH) transmit power level to that of the power level used for Physical SL Shared Channel (PSSCH) so as to prohibit too high transmit power for the PSFCH. In addition, if the difference between the PSSCH and PSFCH exceeds a preconfigured threshold (e.g., the PSFCH is too low), a Receiver (Rx) User Equipment (UE) can take preventive actions that ensure sufficient quality over the PSFCH. In further embodiments, both UEs continuously maintain the estimated SL Path Loss (PL) and transmit a single SL Channel State Information Reference Signal (SCSI-RS), and associated measurement reports rather than triggering new SCSI-RS transmissions and measurement reports for each PSSCH and associated PSFCH channel per SL (e.g., PC5) connection.
