MANAGING CONCURRENT MULTI-RAT UPLINK TRANSMISSIONS AT A USER EQUIPMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18449561 titled 'MANAGING CONCURRENT MULTI-RAT UPLINK TRANSMISSIONS AT A USER EQUIPMENT

Simplified Explanation

- The patent application describes a method for managing uplink transmissions on multiple radio access technologies (RATs) in a user equipment (UE). - The UE receives separate uplink grants for two different RATs, such as 5G NR and LTE. - The UE selectively drops uplink transmissions on specific resource blocks to control the amount of time allocated for concurrent uplink transmissions on both RATs. - This scheduling of uplink transmissions helps in managing the overall time and resources used by the UE for transmitting data on multiple RATs. - The UE also adjusts the transmission of a Buffer Status Report (BSR) on the first RAT based on the scheduling of concurrent uplink multi-RAT transmissions during a specific period of time. - During another period of time, the UE does not transmit a BSR on the first RAT when concurrent uplink transmissions on both RATs are not allowed to be scheduled. - This approach helps in optimizing the utilization of resources and managing the coordination of uplink transmissions on multiple RATs in the UE.

Original Abstract Submitted

In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.
