  • Methods of UE power saving with multiple receivers
    Patent number: 11622329
    Abstract: A network node in a wireless communication network generates configuration information that configures an extent to which a wireless communication device autonomously adapts a number of different receiver components that the wireless communication device uses under different conditions at the wireless communication device. In some examples, the different conditions may be associated with correlation of propagation channels received at the wireless communication device. The network node transmits the configuration information to the device. Correspondingly, the device autonomously adapts the number of different receiver components that the wireless communication device uses in accordance with the configuration information.

  • Micro sleep for network node providing service to user equipment onboard a high speed train
    Patent number: 11343763
    Abstract: In one aspect, a network node receives a message indicating that UEs that require service are expected to enter a service area of the network node. The network node determines, based on the message, that a change in power management for radio equipment corresponding to the service area is required. The network node determines a timing for initiating the change in power management for the radio equipment, taking into account a predicted time for when the UEs are expected to enter the service area, and triggers the change in power management for the radio equipment, based on the determined timing. In another aspect, the network node predicts a departure time from the first service area for the UEs. The network node then sends to another network node, prior to the predicted departure time, an indication that the UEs are expected to enter a service area of the other network node.

  • Synchronization for extended DRX
    Patent number: 11317364
    Abstract: A wireless communication device in a 3GPP NB-IoT wireless communication network operates during an inactivity period of an eDRX cycle. An activation procedure comprises calculating, in a time reference frame inherent to the wireless communication device, an earliest and a latest point in time for obtaining a narrowband master information block (MIB-NB) transmitted by a network node in a narrowband physical broadcast channel (NPBCH) during a single NPBCH transmission time interval. Between the calculated earliest point in time and latest point in time, radio receiver circuitry is activated in the wireless communication device and at least one radio subframe comprising the NPBCH is received and decoded. By this decoding, the MIB-NB is obtained, from which a system frame number (SFN) is read. A communication procedure then comprises activating the wireless communication device according to the eDRX cycle, and communicating, in a designated time interval as determined by the SFN, with the network node.

  • 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.
