  • Patent number: 12034641
    Abstract: A method for autonomously selecting data routing path by a distributed system includes forming a pulse group comprising a plurality of nodes in a computer network, automatically measuring one-way latencies between nodes in the pulse group, recording the one-way latencies in a one-way latency matrix, automatically determining a lower-latency data routing path from a first node to a second node through a relay node using in the one-way latency matrix. The lower-latency data routing path has a lower sum of one-way latencies from the first node to the second node via the relay node than the one-way latency for the direct path between from the first node to the second node. Data is sent from the first node to the second node via the relay node along the lower-latency data routing path. A payment transfer is automatically recorded in response to the data transmission along the lower-latency data routing path.

  • Patent number: 11096127
    Abstract: The disclosure provides a method and a device in a User Equipment (UE) and a base station for terminal-to-terminal communication. The UE first receives K downlink radio signals, and then transmits a first radio signal. A transmit power value of the first radio signal is a first power value. The K downlink radio signals are associated with K synchronization sequences respectively. The downlink radio signal includes at least one of a downlink reference signal or a synchronization signal, or the downlink radio signal includes a downlink signaling. The K downlink radio signals are used for determining the first power value. Any two of the K synchronization sequences are different. The K is a positive integer greater than 1. A relationship is established between the first power value and the K downlink radio signals, ensuring that transmissions of the UE will not produce strong interferences to neighbor cells.

  • Patent number: 11032783
    Abstract: Methods, systems, and devices for wireless communication are described. A per-frequency indication providing deployment options for communication with a core network may be used for enhanced cell selection by a user equipment (UE). For example, system information transmitted by a base station may provide information elements that indicate, per radio frequency (or per radio frequency (RF) spectrum band)), deployment options associated with nearby cells. In such cases, the UE may determine whether to access the radio frequencies or RF bands of these cells based on the capabilities of the UE. In some cases, the UE may further determine whether the nearby cells are available based on the availability of a service through those cells. Accordingly, the UE may select one of the radio frequencies or bands corresponding to the cell having a network connectivity configuration that supports the UE's capabilities.
