Title:
SYSTEMS AND METHODS FOR HANDLING SIDELINK FEEDBACK SIGNALING
Document Type and Number:
WIPO Patent Application WO/2021/068916
Kind Code:
A1
Abstract:
Techniques for handling sidelink feedback signaling in situations where collisions would otherwise be experienced in a network communication link are shown and described. For example, sidelink feedback signaling handling techniques may provide for collision handling when sidelink HARQ is to be simultaneously transmitted with network communication radio interface uplink channel information (e.g., Uu HARQ, SR, CSI, etc. ) on one or more Uu channel (e.g., PUCCH, PUSCH, etc. ). In operation of sidelink feedback handling, a transmitter or intermediary UE of a sidelink communication link may decide whether and how to forward the sidelink HARQ to a corresponding base station. Other aspects and features are also claimed and described.
