Title:
TRIGGERING DROPBACK FOR LATENCY SENSITIVE SERVICE
Document Type and Number:
WIPO Patent Application WO/2021/237581
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support dual connectivity (DC) between different radio access technologies (RATs), such as Long Term Evolution (LTE) and New Radio (NR). In some cases, a user equipment (UE) may run an application associated with latency sensitive service. However, an NR connection may fail to support a data rate used for the latency sensitive service. Based on the signal quality of the NR connection, the UE may release the NR connection and modify criteria for triggering a measurement report to re- establish the NR connection. For example, the UE may use an additional threshold, an additional offset value, or both as compared to a baseline criteria to trigger the measurement report transmission. This modified criteria may allow the UE to dropback and use the LTE connection for running the latency sensitive service rather than re-establish the NR connection.
