    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.

    Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.

    Abstract: Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs. The linkage may be made through information elements in the measurement resource configuration parameters or the measurement gap configuration parameters containing the MGP.

    Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.
