  • Controlling energy consumption of a wireless network node
    Patent number: 11696238
    Abstract: A user equipment receives a signal indicating a time schedule for intermittent transmission of information from a base station managing a cell. The intermittent transmission of information enables the UE to perform mobility measurements when the cell is in a discontinuous transmission (DTX) mode and the UE is an active terminal not served by the cell. The UE performs, based on the intermittent transmission of information, a mobility measurement when the cell is in the DTX mode and reports the mobility measurement to the base station.

  • Method and network node for enabling wireless communication with a wireless device
    Patent number: 11570725
    Abstract: A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set.

  • Method and a first device for clock synchronization
    Patent number: 11329746
    Abstract: A method and a first device (110A) for synchronizing a first clock in the first device (110A) with a second clock in a second device (110B). The first device (110A) estimates 5 (A430) a relative clock phase offset, based on a sequence of round trip times, RTTs, of precision time protocol, PTP, messages which are exchanged between the first and second devices (110A, 110B). The estimated relative clock phase offset is a time difference between a time of arrival of a first arrived PTP message among the PTP messages and a direct subsequent clock cycle. The first device (110A) further determines 10 (A450) a clock value of the first clock, based on the estimated relative clock phase offset, to synchronize the first clock with the second clock.

Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.
