Preconfigured uplink resource techniques in wireless communications

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for transmitting a preconfigured uplink resource (PUR) request message to an access network entity based at least in part on determining that the access network entity supports preconfigured uplink resources, wherein the PUR request message includes a number of instances of PUR grants requested by the UE;
• and
• means for receiving a message from the access network entity indicating a PUR configuration, wherein the PUR configuration comprises a delta configuration that indicates at least one difference over a configuration of the UE.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by one or more processors individually or collectively to:

• transmit a preconfigured uplink resource (PUR) request message to an access network entity based at least in part on determining that the access network entity supports preconfigured uplink resources, wherein the PUR request message includes a number of instances of PUR grants requested by the UE;
• and
• receive a message from the access network entity indicating a PUR configuration, wherein the PUR configuration comprises a delta configuration that indicates at least one difference over a configuration of the UE.

A method for wireless communication at a user equipment (UE), comprising:

• transmitting a preconfigured uplink resource (PUR) request message to an access network entity based at least in part on determining that the access network entity supports preconfigured uplink resources, wherein the PUR request message includes an indication that one PUR grant instance is requested by the UE or an infinite number of PUR grant instances are requested by the UE;
• and
• receiving a message from the access network entity indicating a PUR configuration or PUR reconfiguration or release of preconfigured uplink resources, wherein the PUR configuration comprises a delta configuration that indicates at least one difference over a prior PUR configuration of the UE.
