Inter-radio access network mobility enhancements for reduced capability user equipment

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

• receiving a system information block one (SIB1) message via a first radio access network (RAN) that indicates a return allowance state for the UE that identifies whether the UE is allowed to reconnect to the first RAN from a second RAN, wherein the return allowance state is based on an operation mode of the UE;
• performing a mobility procedure from the first RAN to the second RAN, wherein the first RAN supports a set of services that are not supported by the second RAN;
• and
• performing a reconnection procedure from the second RAN to the first RAN when both the second RAN and the first RAN are available to the UE, wherein the reconnection procedure is based at least in part on the indication, by the return allowance state or a return allowance time window, that the UE is allowed to reconnect to the first RAN.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:

• receive a system information block one (SIB1) message via a first radio access network (RAN) that indicates a return allowance state for a user equipment (UE) that identifies whether the UE is allowed to reconnect to the first RAN from a second RAN, wherein the return allowance state is based on an operation mode of the UE;
• perform a mobility procedure from the first RAN to the second RAN, wherein the first RAN supports a set of services that are not supported by the second RAN;
• and
• perform a reconnection procedure from the second RAN to the first RAN when both the second RAN and the first RAN are available to the UE, wherein the reconnection procedure is based at least in part on the indication, by the return allowance state or a return allowance time window, that the UE is allowed to reconnect to the first RAN.
