CONTROL MECHANISMS FOR BANDWIDTH PART SWITCHING FOR MULTIPLE SUBSCRIBERS - A simplified explanation of the abstract

  • This abstract for appeared for patent application number 17716455 Titled 'CONTROL MECHANISMS FOR BANDWIDTH PART SWITCHING FOR MULTIPLE SUBSCRIBERS'

Simplified Explanation

This abstract describes methods, systems, and devices for wireless communications. It explains that a user equipment (UE) can be configured with multiple bandwidth parts (BWPs) and support multiple subscriber identification modules (SIMs) in a multi-SIM (MSIM) mode. The UE may temporarily switch away from its default data SIM (DDS) subscription, resulting in a gap where it may miss downlink signaling, such as an indication of a BWP switch. To prevent latency caused by missed signaling, the UE can autonomously switch to a different BWP without waiting for a command from the network. This can be achieved by transmitting a scheduling request (SR) on each configured BWP and monitoring for responsive signaling.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may be configured with multiple bandwidth parts (BWPs) and may support multiple subscriber identification modules (SIMs) (e.g., may operate in a multi-SIM (MSIM) mode). The UE may tune away from a default data SIM (DDS) subscription for a tune away gap and may miss any downlink signaling, such as an indication of a BWP switch, for a duration of the tune away. To avoid latency resulting from such missed downlink signaling, the UE may support a mechanism according to which the UE may autonomously switch to a different BWP despite a missed command from a network entity. Such a mechanism may include transmission of a scheduling request (SR) on each of multiple BWPs configured for the UE and monitoring each of the multiple BWPs for signaling responsive to the SR.
