Systems, methods, apparatuses, and computer program products for narrow band internet of things (NB-IoT) paging optimization are provided. One method includes, when extended discontinuous reception (eDRX) is not configured for a user equipment (UE), applying a maximum repetition number of each coverage enhancement (CE) mode for paging transmission and associating a different repetition number with each paging occasion (PO). When extended discontinuous reception (eDRX) is configured for the user equipment, the method includes associating each paging occasion (PO) with a different repetition number. 1. A method , comprising:when extended discontinuous reception (eDRX) is not configured for a user equipment (UE), applying a maximum repetition number of each coverage enhancement (CE) mode for paging transmission and associating a different repetition number with each paging occasion (PO); andwhen extended discontinuous reception (eDRX) is configured for the user equipment, associating each paging occasion (PO) with a different repetition number.2. The method according to claim 1 , wherein the repetition number is derived from at least one of the coverage enhancement (CE) level or a number of paging occasions (POs) within a paging transmission window (PTW).3. The method according to claim 1 , wherein the associating comprises associating said each paging occasion (PO) with a different repetition number based on a pre-defined formula as follows:{'br': None, 'i': I', '=I', 'N', 'N', 'N', 'N, 'sub': repetition', 'po', 'repetition', 'po', 'repetition', 'po, '·[(−1)/(−1)]+(−1)%(−1),'}{'sub': po', 'repetition', 'po', 'repetition, 'where Nis the number of POs within a paging transmission window (PTW), Nis the number of repetitions within C where C is the set of repetition number, Iis the index of the paging occasion (PO) inside the paging transmission window (PTW), and Iis the index of the repetitions within the repetition set.'}4. The method according to claim 2 , wherein ...
