  • Patent number: 11864150
    Abstract: A method and network node for uplink coordinated multipoint positioning are disclosed. According to one aspect, a method includes employing a coordinated multipoint function to decode data from a WD using signals received from the WD by the network node and from signals received from the WD by a plurality of cooperating network nodes. The method further includes converting the decoded WD data signal into a time domain reference signal and convert the signals received from the plurality of cooperating network nodes into time domain neighbour signals. The method also includes cross-correlating the time domain reference signal with the time domain neighbour signals to determine a time difference of arrival for each of the plurality of time domain neighbour signals. The method also includes calculating a position of the WD based on the time differences of arrival and based on locations of the cooperating network nodes.

  • Patent number: 11747429
    Abstract: A method and network node for differential matched summed antenna positioning are disclosed. According to one aspect, a method includes summing sequential uplink data signals at each of a plurality of antennas of the network node to produce a plurality of antenna signal sums. The method also includes selecting one of the antenna signal sums to be used as a reference antenna signal sum. A channel impulse response is determined for each of a plurality of other antennas by cross correlating the reference antenna signal sum with the others of the plurality of antenna signal sums. The method further includes estimating a time difference of arrival from the channel impulse responses of the plurality of antennas, and estimating an error of the estimated time difference of arrival of each antenna. A position of a wireless device is determined using the estimated time differences of arrival.

  • Publication number: 20220183037
    Abstract: Embodiments include methods, performed by a network node, for transmitting data on a shared channel in a wireless network. Such methods include performing a plurality of listen-before-talk (LBT) assessments for a corresponding plurality of substantially disjoint subsets of resources of a shared channel and, based on the plurality of LBT assessments, determining that at least one resource subset is available for transmission. Such methods also include transmitting signals or data to one or more user equipment (UE) using only resources selected from the at least one resource subset. For example, determining availability of resource subsets can be based on a threshold, for each resource subset, that is related to the size of the resource subset. Resource subsets can include adjacent spatial regions having substantially non-overlapping ranges of azimuths and elevations, and/or sub-bandwidths within a bandwidth of the shared channel. Other embodiments include network nodes configured to perform such methods.
