Assuming the new data arrival will trigger SR based on different SR configurations from SR configuration of ongoing SR transmission, the following possible solutions regarding how to handle SR transmission(s) based on the multiple SR configurations in case A are proposed:
Solution 1 (Parallel SR transmissions based on multiple SR configurations)—In this solution, the UE can support to transmit multiple SR transmissions based on different SR configurations. The multiple SR transmissions may occur on same or different cells (e.g. all on PCell or one on PCell, other on SCell). Hence, the new uplink data arrival event triggers SR transmission based on a SR configuration, while current SR transmission performed based on another SR configuration.
Based on this solution, the network can derive more information from SR transmissions belonging to the same UE. For example, if ongoing event is for delay sensitive data and new data arrival is for latency endurable data, parallel multiple SR transmission based on different SR configurations can help network (e.g. gNB) to provide data resource for delay sensitive for satisfying the need of both new events and current event.
Solution 2 (Update SR transmission to reflect highest priority need (either new event or current buffer size)—The UE may or may not support parallel multiple SR transmissions based on different SR configurations. If the UE does not support, the UE will need to stop current SR transmission for initiating SR transmission based on a SR configuration different from current used SR configuration.
