1. A user equipment (UE), comprising:
- at least one antenna;
at least one radio coupled to the at least one antenna for performing wireless cellular communications with a cellular network; and
at least one processing element coupled to the at least one radio, wherein the UE is connected to a network using a first radio access technology (RAT), wherein the UE is configured to;
determine a first resource requirement for communication on the network using the first RAT and a second resource requirement for communication on the network using a second RAT; and
trigger a re-selection to the second RAT in response to the UE determining that the second RAT is preferred over the first RAT based, at least in part, on a comparison of the first and second resource requirements.

Abstract
According to techniques described herein, a UE (which may be link budget limited) may be connected to a network using a first RAT. The UE may be configured to determine a first resource requirement for communication on the network using the first RAT and a second resource requirement for communication on the network using a second RAT. The UE may be further configured to trigger a re-selection to the second RAT in response to the UE determining that the second RAT is preferred over the first RAT based, at least in part, on a comparison of the first and second resource requirements.

9. A method, comprising:
by a user equipment device (UE) comprising at least one antenna, at least one radio coupled to the at least one antenna for performing wireless cellular communications with a cellular network, and at least one processing element coupled to the at least one radio, wherein the UE is connected to a network using a first radio access technology (RAT), the method comprising; determining a first resource requirement for communication on the network using the first RAT and a second resource requirement for communication on the network using a second RAT; and triggering a re-selection to the second RAT in response to the UE determining that the second RAT is preferred over the first RAT based, at least in part, on a comparison of the first and second resource requirements. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A non-volatile computer-readable medium that stores program instructions that, when executed by a processor of a user equipment device (UE), cause the UE to:
-
determine a first resource requirement for communication on a network using a first radio access technology (RAT) and a second resource requirement for communication on the network using a second RAT; and trigger a re-selection to the second RAT in response to the UE determining that the second RAT is preferred over the first RAT based, at least in part, on a comparison of the first and second resource requirements. - View Dependent Claims (17, 18, 19, 20)
