1. A method by a terminal, the method comprising:
transmitting by the terminal a UECapabilityInformation to a base station, the UECapabilityInformation includes a first capability information and one or more second capability information, the first capability information indicates whether the terminal supports RRC_INACTIVE, the second capability information indicates whether the terminal supports transmission of data in RRC_INACTIVE state;
receiving by the terminal a RRCRelease, the RRC release message includes a first information for second resume procedure, the first information for second resume procedure includes a Signaling Radio Bearer2 (SRB2) indicator and a Data Radio Bearer (DRB) list;
receiving by the terminal a system information, the system information includes a first threshold and a second threshold, the first threshold is related to a reference signal reception power and the second threshold is related to a data volume;
initiating by the terminal a second resume procedure; and
cancelling by the terminal triggered Power Headroom Report (PHR) if the second resume procedure is ongoing and if the uplink grant can accommodate all pending data available for transmission but is not sufficient to accommodate all pending data available and PHR Medium Access Control (MAC) Control Element (CE) and PHR MAC CE's subheader.
