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.

Abstract: A method and apparatus may include configuring, by a base station, a synchronization signal. The synchronization signal may be aligned with a sub carrier spacing grid of a radio access technology. The synchronization signal may be positioned at a frequency location that is the same or about the same as a frequency step of a channel raster. The synchronization signal may be transmitted to a user equipment so that the center of the synchronization signal is transmitted with a frequency offset with respect to the center of the radio-access technology bandwidth.

Abstract: In accordance with the example embodiments of the invention there is at least a method an apparatus to perform determining signaling comprising at least one wake-up signal to indicate an occurrence or a non-occurrence of a paging request associated with a next paging occasion of a network device; and sending the signaling comprising the at least one wake-up signal toward a network device in a communication network, wherein the at least one wake-up signal is to cause the network device to determine whether to leave at the next paging occasion an energy saving sleep mode to receive the paging request. Further, there is performing receiving by a network device in a communication network at least one wake-up signal to indicate an occurrence or a non-occurrence of a paging request, wherein the at least one wake-up signal is for use by the network device to determine whether to leave at its next paging occasion an energy saving sleep mode to receive the paging request.

Abstract: A method and apparatus to determine by a network node of a serving cell of a communication network signaling including at least one parameter indicating that page reception on a paging channel of a neighbor cell can be performed by a network device without system information acquisition by the network device; and send the signaling toward the network device. Further, a method and apparatus to receive by a network device of a communication network from a serving cell signaling including at least one parameter indicating that page reception on a neighbor cell by a network device can be performed by the network device without system information acquisition by the network device; and based on the signaling, listen for a paging message on a paging channel associated with the neighbor cell without system information acquisition.
