摘要： The gain of an amplifier in a receiver operating in a cellular communication system is controlled by determining one or more gain variability metrics, which are then used to produce first and second threshold values. A frequency difference between a current carrier frequency and a target carrier frequency is ascertained and then compared to the threshold values. Target gain setting production is based on comparison results: If the frequency difference is larger than the first threshold, a full automatic gain control algorithm is performed; if the frequency difference is smaller than the first threshold and larger than the second threshold, an optimized automatic gain control algorithm is performed, wherein the optimized automatic gain control algorithm uses a current gain setting as a starting point; and if the frequency difference is smaller than both the first and second thresholds, the current gain setting is used as the target gain setting.

摘要： In one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the measurement rate to use for making inter-frequency measurements on a given frequency layer, based on a performance requirement specified for that layer. For example, the wireless device uses a higher measurement rate for a frequency layer that has a performance requirement that is higher than the performance requirement specified for another one of the layers on which it is to perform inter-frequency measurements. Correspondingly, in an example scenario, a network node sends measurement configuration information to a targeted device, where that information indicates the layers on which the device is to perform inter-frequency measurements and indicates the performance requirements corresponding to respective ones of those layers. By way of example, the network node may be a base station, a relay, or another wireless device.
