Abstract

Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for cell measurement associated with a frequency hopping system. The base station may then receive a measurement report based on the configuration. A UE may receive a configuration for cell measurement associated with a frequency hopping system. The UE may generate a measurement report based on the configuration. The UE may then transmit the measurement report to a serving base station.
