repeated in a set of R consecutive NB-IoT downlink subframes excluding subframes used for transmission of system information messages starting with subframe k [4]. Thus each NPDCCH may be repeated several times with an upper limit configured by the RRC signal- ing. In addition, Type-2 common search space and UE-specific search space are configured by RRC, whereas the Type-1 common search space is identified by the paging opportunity subframes. The location of NPDCCH (i.e., the subframes used for transmitting NPDCCH) is determined via a process as illustrated in Fig. 6.14. In case of Type-1 NPDCCH common search space, k = ko, which is determined from locations of NB-IoT paging opportunity subframes. Different radio network temporary identifiers (RNTIs) are assigned to each UE, one for ran- dom access (RA-RNTI), one for paging (P-RNTI), and a UE-specific temporary identifier (C-RNTI) provided during the random-access procedure. These identifiers are implicitly indicated (scrambled) in the NPDCCH CRC. Therefore, the UE has to search for a specific RRC parameter npdcch-Offset-USS (NPDCCH UE-specific search space) RRC parameter npdcch-Offset-RA (NPDCCH Type2-NPDCCH common search space) RRC parameter inpdcch-Offset-SC-MTCH (NPDCCH Type2A-NPDCCH common search space) RRC configured parameter inpdcch-NumRepetitions RRC configured parameter npdcch-Num RepetitionPaging for Type1-NPDCCH common search space RRC configured parameter npdcch-Num Repetitions-SC-MCCH for Type1A-NPDCCH common search space RRC configured parameter npdcch-Num Repetitions-RA for Type2-NPDCCH common search space RRC configured parameter npdcch-Num Repetitions-SC-MTCH for Type2A-NPDCCH common search space RRC parameter npdcch-StartSF-USS (NPDCCH UE-specific search space) RRC parameter inpdcch-StartSF-CSS-RA (NPDCCH Type2-NPDCCH common search space) RRC parameter inpdcch-startSF-SC-MTCH (NPDCCH Type2A-NPDCCH common search space) T = max modT= Offset The value of R is determined by DCI u =0,1, subframe repetition number in DCI (see Subframe ko that 3GPP T
