  • Patent number: 11424785
    Abstract: A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of N?Mk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of N?Mk targeted lines.

  • Patent number: 11349675
    Abstract: An authentication request message is sent from a first computing device to a second computing device, wherein the first computing device and the second computing device communicate via a machine-to-machine communication protocol, and wherein the authentication request comprises a token issued by the second computing device and stored in a key obfuscation block of the first computing device. A challenge message is received at the first computing device from the second computing device. In response to the challenge message, a session key is computed at the key obfuscation block of the first computing device, wherein the session key is computed based on a secret shared between the first computing device and the second computing device. Upon generating the session key, the first computing device extracts a value from the challenge message and generates an authentication delegate based on the extracted value.

  • Patent number: 11297601
    Abstract: A resource allocation method for network slicing and an orchestrator, comprising: uniformly incorporating resources originally bundled statically with the base station into a dynamic resource pool; allocating, by an orchestrator, resources from among the dynamic resource pool for the network slicing based on different network slicing requirements. A static corresponding/mapping relationship between the hardware/radio resources and the base station is broken, such that hardware/radio resources (e.g., radio access network Virtual Network Function (RAN VNF), baseband unit (BBU), RRH (Remote Radio Head) as well as antenna) that originally corresponded to different base stations will be organized as an integrated and dynamic hardware/radio resource pool and reported to the orchestrator, such that the orchestrator will centrally manage all hardware/radio resources in this pool and then sufficiently utilize and dynamically orchestrate these hardware/radio resources based different needs from the network slicing.

  • Patent number: 11284338
    Abstract: A base station for a multiple-input, multiple-output (MIMO) array receives a message that includes information identifying the transmitting and receiving nodes. Based on whether the base station has access to up-to-date channel covariance matrices for the nodes, the base station selectively performs a clear channel assessment in an unlicensed frequency band concurrently with placing nulls in directions associated with the nodes. In some cases, the up-to-date channel covariance matrices are used to place nulls in the directions associated with the nodes concurrently with performing the clear channel assessment in response to the up-to-date channel covariance matrices being available to the base station. Placement of nulls in the directions associated with the nodes is bypassed in response to the up-to-date channel covariance matrices not being available to the base station.
