RANDOM ACCESS PROCEDURE OPTIMIZATION FOR ENERGY HARVESTING SDT DEVICES
This abstract first appeared for US patent application 18722458 titled 'RANDOM ACCESS PROCEDURE OPTIMIZATION FOR ENERGY HARVESTING SDT DEVICES
Original Abstract Submitted
A network node may determine a congestion level of a random access channel; and may transmit, to one or more energy constrained user equipments, at least one barring parameter, wherein the at least one barring parameter may be based, at least partially, on the determined congestion level and an energy constraint of the one or more user equipments. An energy constrained user equipment may receive a system information block comprising a barring factor and a back-off time; may determine whether to transmit a preamble for a random access procedure based, at least partially, on the barring factor and a maximum number of preamble transmission attempts; may transmit the preamble based on a determination to do so, or may wait for the back-off time based on a determination to not do so.
