A radio access network, RAN, node (102 2) configured to interact with a core network, CN, node and a wireless device (104 2), the RAN node comprising: a processor (132 2); and, a memory (134 2) that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the RAN node is operable to: receive, from the wireless device, one or more repetitions of an access request message, wherein the access request message comprises: an indication of a number of data blocks (202 1, 202 2...202 x) the wireless device intends to transmit to the RAN node; and transmit, to the wireless device, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises: an indication of a number of pre-allocated radio blocks on a packet data traffic channel; an indication (N TX, UL) of an Uplink, UL, coverage class; and an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node, wherein the pre-allocated radio blocks are allocated such that all repetitions of each of the data blocks are to be transmitted contiguously by the wireless device, and wherein the pre-allocated radio blocks are allocated such that each of the data blocks does not need to be transmitted contiguously with respect to one another by the wireless device. a processor (132 2); and, a memory (134 2) that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the RAN node is operable to: receive, from the wireless device, one or more repetitions of an access request message, wherein the access request message comprises: an indication of a number of data blocks (202 1, 202 2...202 x) the wireless device intends to transmit to the RAN node; and transmit, to the wireless device, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises: an indication of a number of pre-allocated radio blocks on a packet data traffic channel; an indication (N TX, UL) of an Uplink, UL, coverage class; and an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node, receive, from the wireless device, one or more repetitions of an access request message, wherein the access request message comprises: an indication of a number of data blocks (202 1, 202 2...202 x) the wireless device intends to transmit to the RAN node; and transmit, to the wireless device, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises: an indication of a number of pre-allocated radio blocks on a packet data traffic channel; an indication (N TX, UL) of an Uplink, UL, coverage class; and an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node, an indication of a number of pre-allocated radio blocks on a packet data traffic channel; an indication (N TX, UL) of an Uplink, UL, coverage class; and an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node, wherein the pre-allocated radio blocks are allocated such that all repetitions of each of the data blocks are to be transmitted contiguously by the wireless device, and wherein the pre-allocated radio blocks are allocated such that each of the data blocks does not need to be transmitted contiguously with respect to one another by the wireless device.
