A mechanism is described herein for enhancing the radio coverage for a wireless device based on an exchange of uplink and downlink radio condition information, referred to as uplink and downlink Radio Coverage Category (RCC) values, between the wireless device and a network (e.g., a Radio Access Network (RAN) node, Core Network (CN) node) for use in data transmission (e.g., control plane related signaling or user plane related payload transmission). |

1. A wireless device configured to communicate with a Radio Access Network (RAN) node and a Core Network (CN) node, the wireless device comprising:
a processor; and, a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the wireless device is operable to:
receive, from the RAN node, control channels;estimate a downlink radio condition based on a signal quality of the received control channels;map the estimated downlink radio condition to one of a plurality of downlink Radio Coverage Category (RCC) values;transmit, to the RAN node, one or more access burst (AB) based first messages per an uplink RCC value, wherein each of the one or more AB based first messages includes the one downlink RCC value;determine that a first AB based system access failed after transmitting the one or more AB based first messages; andupon the determination that the first AB based system access failed:
increment the one downlink RCC value, the uplink RCC value, or both the one downlink RCC value and the uplink RCC value; andtransmit, to the RAN node, one or more access burst (AB) based second messages per the uplink RCC value, if not incremented, or the incremented uplink RCC value, if incremented, wherein each of the one or more AB based second messages includes the one downlink RCC value, if not incremented, or the incremented one downlink RCC value, if incremented. |
