Published: — with international search report (Art. 21(3)) (54) Title: SCHEDULING REQUESTS AND BUFFER STATUS REPORTS FOR LOW LATENCY WIRELESS COMMUNI- CATIONS (57) : A base station may transmit a grant to user equip- ment (UEs), indicating uplink resources for transmission of pend- ing data at a UE. Uplink resources may include uplink resources associated with transmission time intervals (TTIs) and/or shortened TTIs (sTTIs). A UE may identify pending data associated with a data type (e.g., low latency data, internet traffic, etc.) and transmit a scheduling request (SR) for a grant of uplink resources. The data type of the pending data (e.g., the logic channel group identification (LCG ID) associated with a buffer status) may be indicated such that uplink resources may be granted to the UE to reduce latency. In some aspects, the SR may indicate uplink resources associated with sTTIs. Further, the UE may prioritize pending data and buffer status reports (BSRs) associated with other data within the received grant. W O 20 18/ 175 9 19 Al 200 FIG. 2
