Abstract: Network initiated re-authorization for coverage enhancement It is provided a method, comprising checking if a device is authorized for initiating an access in an extended coverage; inhibiting the device to initiate the access while the device camps in the extended coverage and the device is not authorized for the initiating of the access in the extended coverage; monitoring if a paging message for the device is received while the device camps in the extended coverage, wherein the paging message is to initiate a signaling access in the extended coverage for a signaling procedure to get the latest status of coverage authorization; allowing the device to initiate the signaling access while the device camps in the extended coverage if the paging message is received.

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.
