Methods and systems for managing temperature of 5G UE by TX/RX path switching. If temperature of the UE increases beyond a preconfigured threshold due to heat contributed by a first TX/RX path of the UE, embodiments perform switching from the first TX/RX path to a second TX/RX path to control the temperature of the UE. The first TX/RX path and the second TX/RX path correspond to the same or different RF bands. If the first TX/RX path and the second TX/RX path correspond to different RF bands, the UE sends, to a wireless network, either: a measurement report, indicating that RSRP of a cell corresponding to the second TX/RX path is greater than RSRP of the serving cell corresponding to the first TX/RX path; or a UE Assistance Information indicating that the UE intends to camp on the cell corresponding to the second TX/RX path of the UE.
