  • Network Architecture, Methods, and Devices for a Wireless Communications Network
    Publication number: 20230224059
    Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

  • Determination of directional beamforming weights
    Patent number: 11342982
    Abstract: Mechanisms for determining directional beamforming weights are disclosed. A method performed by a radio transceiver device includes obtaining, from measurements on reference signals, channel estimates per antenna port and frequency. The channel estimates are indicative of power delay values per antenna port towards another radio transceiver device. The method includes determining modified channel estimates per antenna port and frequency with the power delay values outside a threshold delay window being suppressed. The method includes determining directional beamforming weights for beam-formed transmission towards said another radio transceiver device based on the modified channel estimates per antenna port and frequency.

  • Radio antenna positioning
    Patent number: 10644377
    Abstract: A method (400) for positioning a first and a second radio antenna comprising the steps of configuring (SI) the first antenna to have a main lobe L1 and configuring (52) the second antenna to be a directive antenna having a main lobe L2. The method also comprising the steps of transmitting (S3) a first alignment signal from the first antenna to the second antenna and positioning (S4) the second antenna based on the received first alignment signal, as well as reconfiguring (S5) the first antenna to be a directive antenna having an antenna main lobe L3, the antenna main lobe L3 having a more narrow main lobe width than the antenna main lobe L1. The method provides a systematic approach to finding optimum antenna positions and corresponding main lobe directions which is especially suited for aligning directive radio antennas in NLOS communication scenarios.

    Publication number: 20200120482
    Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.
