Claim of US Patent No. 10,716,098

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; to estimate a downlink radio condition based on a signal quality of the received control channels; to map the estimated downlink radio condition to one of a plurality of downlink Radio Coverage Category (RCC) values; to transmit, to the RAN node, a first message including the one downlink RCC value; to receive, from the RAN node, a second message having a number of repeated downlink transmissions based on the one downlink RCC value; to receive, from the RAN node, a paging message including an uplink RCC value and having a number of repeated paging downlink transmissions, wherein the number of repeated paging downlink transmissions is determined based on a second downlink RCC value; and to transmit, to the RAN node, a paging response having a number of repeated uplink transmissions determined based on the uplink RCC value in the paging message.
