WebThis preamble is then transmitted using the PRACH to the eNodeB (eNB). In each PRACH, if two or more MTC devices select the same preamble, the eNB will be unable to identify the initiator of the RA since the devices don’t indicate their own identities in this request. Thus, eNB cannot decode any of these preambles and a collision will happen. • WebThe RA-RNTI associated with the PRACH in which the Random Access Preamble is transmitted, is computed as: RA-RNTI = 1 + t_id + 10 * f_id. Where t_id is the index of the first subframe of the specified PRACH (0 <≤ t_id <10), and f_id is the index of the specified PRACH within that subframe, in ascending order of frequency domain (0≤ f_id< 6).
