    Abstract: Techniques for grouping multiple serving component carriers (CCs) are disclosed. In one example, a frequency separation that defines a frequency range from a lower bound frequency to a higher bound frequency for each CC group of a plurality of CC groups may be determined, wherein a difference between the lower bound frequency and the higher bound frequency of each CC group may be equal to the frequency separation. A frequency of a first CC from a collection of CCs may be determined. The first CC may be assigned to a first CC group, of the plurality of CC groups, wherein the first CC group may have a frequency range that includes the frequency of the first CC.

  • Publication number: 20230370217
    Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

  • Publication number: 20230362664
    Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.
