Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of extended bandwidth allocation. In example embodiments, a first device receives, from a second device, an indication of a reference bandwidth. The first device receives, from the second device, an indication of a bandwidth extended from the reference bandwidth and receives, from the second device, an indication of at least one frequency offset of a first set of narrowbands with respect to a second set of narrowbands associated with the reference bandwidth. Then, the first device determines, based on the reference bandwidth, the extended bandwidth and the at least one frequency offset, the first set of narrowbands for communication with the second device.

Abstract: Systems, methods, apparatuses, and computer program products for a modified multi-slot random access channel (RACH) transmission, such as an extended coverage RACH (EC-RACH) transmission, are provided. One method includes transmitting, by a mobile station associated with a network, a dual slot hybrid random access channel including a long burst followed by one access burst or including one access burst followed by one long burst. Two consecutive time slots may be used for the random access channel transmission.
