Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more threshold criteria are satisfied, wherein the one or more threshold criteria include at least one of a first value for an uplink grant rate, a second value for a buffer size, or a third value for a packet data convergence protocol discard rate, wherein the one or more threshold criteria relate to a network condition with less than a reference uplink throughput and greater than a reference downlink throughput. The UE may transmit information identifying one or more adjusted measurement values based at least in part on the determination of the one or more threshold criteria. Numerous other aspects are described.
