## Abstract

Wireless communication techniques that include multi-beam techniques for small data transfer (SDT) over preconfigured uplink resources (PURs) are discussed. A UE may receive an indication of at least one PUR allocated for uplink communication when the UE does not have a RRC connection with a base station. The at least one PUR may include one or more distinct PUR occasions. The UE may also receive an indication of one or more distinct SSBs associated with the one or more distinct PUR occasions. Each PUR occasion of the one or more distinct PUR occasions may be associated with only one SSB of the one or more distinct SSBs. The CE may also transmit information to the base station during a PUR occasion associated with an SSB that is associated with a RSRP that is greater than a threshold. Other aspects and features are also claimed and described.
