Idle UE Activation Using Preallocated 5G Beam Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently transitioning idle user equipment to active mode due to limited radio resources and beam-steering issues, leading to attach failures and delays, especially in environments where network footprints do not encompass idle user equipment.
Innovation Solution
Implementing a multi-connectivity framework that utilizes preemptive allocation and direction of radio resources based on signal propagation information and interference data to facilitate a predicted transition to active mode by idle user equipment, including the use of mmWave bands for new radio (NR) and sub-6 GHz LTE bands, with network nodes like gNodeB and user equipment like smartphones, to enhance network connectivity.

Engineering Contradiction Analysis
1Speed
If radio resources are allocated preemptively to idle user equipment, then transition speed to active mode is improved, but radio resource consumption increases
Solution Approach 1:
The system performs preliminary actions by allocating radio resources and establishing beam connections before the user equipment actually needs to transition to active mode. Network nodes identify idle user equipment and preemptively allocate radio resources, configure beamforming parameters, and establish preliminary connections so that when activation is needed, the transition occurs rapidly without requiring full resource allocation at that moment.
2Reliability
If beamforming is used to direct radio resources, then connection reliability is improved, but positioning accuracy becomes more challenging
Solution Approach 1:
The system introduces intermediary reference signals and measurement procedures that facilitate accurate positioning despite beamforming. Network nodes transmit reference signals through the beamformed connections, and user equipment provides measurement feedback that enables the network to accurately determine position. This intermediary measurement mechanism reconciles the conflict between directional beamforming and positioning accuracy.

AI summary
The technologies described herein are generally directed to providing, based on a paging message, radio resources to facilitate a transition to active mode by idle user equipment in a fifth generation (5G) network or other next generation networks. An example method can include receiving an instruction to modify a message type to include signal propagation information; generating, by the processing system while the device is in an idle mode, the signal propagation information; transmitting, by the processing system to a network equipment, a message of the message type including the signal propagation information, wherein the signal propagation information is configured for use by the network equipment to allocate an antenna resource for the device; and transitioning, by the processing system, the device from the idle mode to an active mode, the transitioning facilitated by the antenna resource.
