1. A method for triggering an uplink (UL) gap at a base station, the method comprising:
encoding a base station UL gap capability report for transmission to a user equipment (UE);
in response to sending the base station UL gap capability report, decoding a UE UL gap capability report received from the UE;
encoding a radio resource control (RRC) UL gap configuration for transmission to the UE, the RRC UL gap configuration including configuration information associated with at least one of a periodicity, offset, or length;
decoding measurement information received from the UE, the measurement information including at least one of a power headroom value, a configured maximum UE output power (PCMAX,f,c) value for a carrier f of a serving cell c, or a metric (P) value indicating whether a power management maximum power reduction (P-MPR) is applied; and
based on the power headroom value, the PCMAX,f,c value, or the P value, activating the UL gap configuration by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.
