  • Publication number: 20200288418
    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.

  • Publication number: 20200092831
    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.

  • Publication number: 20200084752
    Abstract: A wireless device is configured with or allocated two or more control resource sets for receiving downlink control information from a base station or cell. The two or more control resource sets correspond to two or more possible states of a time slot used for downlink transmission. The wireless device determines the state of a time slot and selects one or the two or more control channel resource sets to monitor for DCI depending on the state of the time slot. In one exemplary embodiment, the time slot has two possible states and the state of the time slot is determined by the presence or absence of an SS block.
