Title: UPLINK TRANSMISSIONS WITHOUT TIMING SYNCHRONIZATION IN WIRELESS COMMUNICATION
Abstract:
Aspects of the present disclosure provide methods, apparatuses, and embodiments for transmitting time critical uplink (UL) control information (e.g., beam failure indication, buffer status report, and scheduling request) without first obtaining UL timing synchronization with a network. Therefore, UL communication latency may be reduced by removing the signaling overhead involved in performing a full random access procedure to obtain UL synchronization prior to UL transmission.
