  • 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.

  • Patent number: 11419071
    Abstract: Adopting a frequency multiplication scheme allows a network node to expand the number of transmit beams transmitted by it within a defined time interval, and allows the network node to transmit a greater number of synchronization signals on a per beam basis within the defined time interval. By way of example, the network node may operate in compliance with standardized restrictions regarding the timeframe during which it must transmit some base number of beam-based synchronization signals, while using a frequency multiplexing scheme to transmit additional beams within the same timeframe. Among the various advantages flowing from these operations, the ability to transmit more beams within the same timeframe allows the network node to tailor the beam shape and directions for broader coverage or enhanced range.
