  • Optimization of automatic gain control for narrow bandwidth operation
    Patent number: 11239871
    Abstract: 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 first automatic gain control algorithm is performed; if the frequency difference is smaller than the first threshold and larger than the second threshold, a second automatic gain control algorithm is performed, wherein the second 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.

  • Serving Cell Activation in a Wireless Communication System
    Publication number: 20210266134
    Abstract: A wireless device (14) is configured to receive an activation command (16) that commands the wireless device (14) to activate a serving cell (18B). The wireless device (14) is configured to activate the serving cell (18B) within a maximum delay (20) since receiving the activation command (16). The maximum delay (20) depends on whether there is at least one other serving cell (18A) already activated for the wireless device (14) in the same frequency band (24) as that in which the serving cell (18B) is to be activated.
