Abstract

According to an example embodiment, a method is provided including: decoding, at a base station of a wireless system, one or more bits of an uplink transmission from a user equipment, wherein the one or more bits are indicative of a channel quality; calculating a confidence metric corresponding to a reliability of the decoding; and causing a channel quality report to be generated based at least on the calculated confidence metric and a value for each system configuration parameter in a limited set of one or more system configuration parameters associated with the base station.

Description

technical field [0001] Various example embodiments relate generally to wireless networks, and more particularly to device-to-device communications in wireless networks. Background technique [0002] In general, wireless networks allow user equipment to provide information about channel quality to the network (eg, such as to a base station). The network can then decide on appropriate settings for subsequent transmissions based on this information, such as selecting an appropriate MCS (Modulation Coding Scheme) for DL ​​transmissions. [0003] Several wireless networks are being designed and implemented to support the growing demand for Machine Type Communication (MTC) and Internet of Things (IoT) services. For example, LTE CAT-M (also known as eMTC, LTE-M, and LTE-MTC) is an extension of existing LTE networks designed to reduce the cost and power consumption of MTC and IoT devices. In LTE CAT-M systems, ACQI (Aperiodic Channel Quality Indication) carried on PUSCH is unrelia...
