Release of preconfigured uplink resource for small data transmission

A method of wireless communication performed by an apparatus, comprising:

• receiving a configuration message, wherein the configuration message includes a preconfigured uplink resource (PUR) configuration for small data transmissions, wherein the PUR configuration comprises preconfigured uplink resources;
• and
• releasing the preconfigured uplink resources based on a PUR release trigger, wherein the PUR release trigger includes satisfaction of a condition corresponding to a timing advance (TA) timer.

A non-transitory, computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• receiving, by a user equipment (UE), a configuration message, wherein the configuration message includes a preconfigured uplink resource (PUR) configuration for small data transmissions, wherein the PUR configuration comprises preconfigured uplink resources;
• and releasing, by the UE, the preconfigured uplink resources based on a PUR release trigger, wherein the PUR release trigger includes satisfaction of a condition corresponding to a timing advance (TA) timer.
