Patent ID: 10104695

Abstract:
Systems described herein receive, via a physical random access channel, an attach request from a user device; retrieve profile data for the user device; and determine, based on RF conditions estimated from the attach request, an initial downlink repetition level for extended coverage. The systems also receive a reference signal from the user device via a physical uplink shared channel; determine an uplink repetition level for coverage extension based on the uplink RF conditions and requirements from the profile data. The systems detect high resource use within a cell; identify a shared downlink resource channel for the user device, wherein machine-type communication (MTC) data for the user device uses BPSK modulation; identify non-MTC data requiring downlink transmission to a device within the cell; and send the non-MTC data over the shared downlink resource channel, and on a resource pre-allocated for the user device, using a different modulation level.
