In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple cov- erage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include im- provements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for nar- rowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband fre- quencies. Determine that coverage conditions of the UE support narrowband frequency hopping for transmissions, wherein the narrowband frequency hopping includes uplink transmission of data without a gap between hopped frequencies 1000 W O 20 18/067 228 Al Indicate, in response to the determining, that the UE is configured with capabilities to support the narrowband frequency hopping without a gap 1001 FIG. 10 [Continued on next page] WO 2018/067228 Al MIDEDIMOMOIDEIRMOIONMEHHOHUMEM# GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
