  • Patent number: 11522592
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a set of beamforming weights, each beamforming weight corresponding to a transmit beam of a set of transmit beams that may each include a same primary lobe and one or more different side lobes. The UE may then perform a beam training procedure to determine which transmit beams cause more or less interference at one or more nearby UEs. The UE may transmit signals using one or more of the transmit beams, and the nearby UEs may determine which transmit beams and corresponding beamforming weights cause more or less interference. The nearby UEs may then indicate those transmit beams or beamforming weights that cause more or less interference via different options.

  • Patent number: 11510226
    Abstract: Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.

  • Patent number: 11432166
    Abstract: The present invention refers to a method and apparatus and computer program for detecting communities in a radio access network with a plurality of vertices (C, BBU), wherein the method comprises calculating (S11) relationship strengths (31, 41) for network connections between the vertices (C, BBU) by executing a connection strength calculation process by analyzing performance factors, decisive for network performance including cell coverage overlap, signal strength, and inter-cell interference. The method further creates (S12) a network graph with nodes, representing the vertices (C,BBU) in the network and edges, representing the network connections based on the calculated relationship strengths (31, 41) and applies (S13) an extended iterative disjoint community detection algorithm for clustering nodes into communities, wherein in each iteration imposed one or more constraints for clustering cooperating nodes into the same community are analyzed (S14).

  • Patent number: 11399353
    Abstract: A telecommunications system communicating data to/from one or more terminals, including one or more transmitters to transmit first and second carriers over respective first and second frequency bandwidths. During a first time period the transmitters can transmit data receivable by first and second classes of terminal on the first and second carriers. During a second different time period, the transmitters can transmit data to the second class of terminal on the first and second carriers in combination. A data transmission format on the first carrier in the first time period is incompatible with a user data transmission format on the second carrier during the first time period. The transmitters can transmit control data on the first carrier in the first time period which is receivable by the second class of terminal to enable the second class of terminal to maintain synchronisation with the first carrier during the first time period.

  • Patent number: 11382103
    Abstract: In environments such as buildings in which access points are densely deployed, those access points influence each other. To provide a frequency channel allocation scheme in such densely populated environments information gathered by the access points are collected. In such a situation, relying on a list of neighboring access points, background noise, communication medium business, the beacon messages received from access points as well as their associated RSSI, may lead to a frequency channel allocation scheme that may not significantly reduce the interference between access points. The invention introduces an activity-based distance computed between at least two access points which represents a time overlap in a use of the communication medium.
