Methods and apparatuses for wireless communication are provided. In some aspects, a user equipment (UE) may obtain a gain value based on a difference between an reference signal receive power (RSRP) value of a first antenna and an RSRP value of a second antenna, where the first antenna may be located on an exterior of the UE and the second antenna may be located within an interior of the UE. Further, in some aspects, the UE may obtain an antenna gain value based at least on a random access channel (RACH) power value and a reference signal receive quality (RSRQ) offset value. Additionally, in some aspects, the UE may obtain the antenna gain value based on one of a matching entry in a memory log or a minimum of a maximum antenna gain value or an aggregation of a RACH gain value and an RSRQ offset value.
