MANAGEMENT OF WIRELESS DEVICES IN LIMITED RADIO COVERAGE

摘要

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).

主权项

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; and to receive, from the RAN node, a second message having a number of repeated downlink transmissions based on the one downlink RCC value.
