AI Technical Summary

Technical Problem

Current wireless communication systems face challenges in efficiently managing reduced bandwidth operations for machine-type communication devices, particularly in reducing channel bandwidth and data rates to lower costs and maintenance needs, while maintaining compatibility with legacy systems.

Method used

A method for a reduced bandwidth wireless transmit/receive unit (WTRU) in machine-type communication (MTC) that determines a paging narrowband based on the most significant bits of a WTRU identifier to monitor the MTC physical downlink control channel, receive downlink control information, and decode associated physical downlink shared channels.

Benefits of technology

Enables efficient paging procedures for reduced bandwidth devices, reducing network costs and maintenance while maintaining compatibility with legacy systems, and supporting devices with limited capabilities such as smartwatches and alarms.

Abstract

To provide a method for paging for a reduced bandwidth wireless transmit / receive unit (WTRU), in new machine type communication (MTC).SOLUTION: A WTRU determines a paging narrowband (NB) for the WTRU used for monitoring an MTC physical downlink control channel (M-PDCCH) on the basis of at least the most significant bit (MSB) of a function of a WTRU-identifier (WTRU-ID). The WTRU monitors the M-PDCCH on the determined paging NB for the WTRU. The WTRU receives downlink control information (DCI) on the monitored M-PDCCH on the determined paging NB during a paging occasion (PO). The WTRU then receives a physical downlink shared channel (PDSCH) associated with the M-PDCCH.SELECTED DRAWING: Figure 6
