  • SYNCHRONIZATION SIGNAL / PHYSICAL BROADCAST CHANNEL BLOCK METHOD DETECTION AND MANAGEMENT
    Publication number: 20220345269
    Abstract: Synchronization signal and Physical Broadcast Channel, SS/PBCH, block management. A network node determines whether a network condition is met, signals to a communication terminal to apply a first detection method for SS/PBCH block detection when the network condition is determined to be met, signals to the communication terminal to apply a second detection method for SS/PBCH block detection when the network condition is determined as not met, and transmits SS/PBCH blocks according to the first or the second SS/PBCH block detection method, based on whether the network condition is met. The communication terminal receives the signalling from the network node associated with the communication network, determines whether the indicated SS/PBCH block detection method is a first or a second SS/PBCH block detection method based on the received signalling, and applies, based on the determination, the first or the second SS/PBCH block detection method for SS/PBCH block detection.

  • OPTIMIZATION OF AUTOMATIC GAIN CONTROL FOR NARROW BANDWIDTH OPERATION
    Publication number: 20220116064
    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.
