1. A method comprising:
determining, by a wireless communication device, a radio network temporary identifier (RNTI) according to an index of a physical random access channel (PRACH) occasion in time domain in which a PRACH preamble is transmitted, wherein the RNTI is determined as a function of t_RO_id, where t_RO_id is the index of PRACH occasion in time domain and has a value which is less than a total number of PRACH occasions in time domain, wherein RNTI is determined according to at least one of:
RNTI=1+t_RO_id,
 RNTI=1+t_RO_id+t_RO_total, where t_RO_total is the total number of PRACH occasions in time domain,
 RNTI=1+t_RO_id+t_RO_total×f_id+t_RO_total×8×ul_carrier_id, where f_id is an index of the PRACH occasion in frequency domain and ul_carrier_id is an identifier of a carrier for random access preamble transmission, or
 RNTI=1+t_RO_id+t_RO_total×f_id+t_RO_total×8×ul_carrier_id+t_RO_total×8× 2; and
detecting, by the wireless communication device, a downlink control information (DCI) format with a cyclic redundancy check (CRC) scrambled with the RNTI.
