  • Patent number: 11464031
    Abstract: Techniques include retrieving from storage a plurality of policies for sharing a shared channel among nodes in a data communications network. The plurality of polices define a tree of periodic schedules of variable periods, each policy defines a transmit time slot as a unique slot i of a modulus of a power m of a base b of a series of time slots, where m indicates a level of the tree of periodic schedules. The method also includes; observing at a first node the probabilities of empty time slots, successful time slots, and collision time slots on the shared channel; selecting at the first node a first policy among the plurality of policies based on the probabilities observed instead of a message received from a central authority; and transmitting a local data packet from the first node onto the shared channel at a transmit time based on the first policy.

  • Patent number: 11438921
    Abstract: A terminal device receives first information including an acknowledgment resource indicator (ARI), and determines, based on the ARI, a first uplink control channel (PUCCH) resource in a PUCCH resource set corresponding to a payload size of a hybrid automatic repeat request acknowledgment (HARQ-ACK). In a case that the first PUCCH resource and a second PUCCH resource partially overlap in terms of time; or the first PUCCH resource and a second PUCCH resource configured for CSI do not overlap in terms of time, and the first PUCCH resource and the second PUCCH resource each partially overlap at least one third PUCCH resource configured for at least one positive scheduling request (SR) in terms of time, the terminal device determines, based on the ARI, a fourth PUCCH resource in a second PUCCH resource set corresponding to a total payload size for sending the HARQ-ACK, CSI, and at least one SR status.

  • Patent number: 11432286
    Abstract: A base station is configured to transmit user data to a wireless device upon a first carrier. The base station identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier, a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station upon a second carrier or by a neighboring base station upon the first carrier. The base station selectively transmits user data to the wireless device upon the first carrier exclusive of this identified subset of transmission resources. The device in some embodiments obtains information indicating that the base station is selectively transmitting user data upon the first carrier exclusive of the subset in this way. Based on this information, the device recovers user data received upon the first carrier exclusive of the subset of transmission resources.

  • Patent number: 11431645
    Abstract: Embodiments of the present disclosure disclose a method and an apparatus for handling network congestion, and a system. The method includes: obtaining a transmitted data volume of a flow, and identifying a predictable flow and a non-predictable flow in the flow; collecting statistics about total data transmission volumes of the predictable flow and the non-predictable flow; obtaining a congestion transmission model of the predictable flow, and solving the congestion transmission model to obtain a scheduling policy for the predictable flow; and allocating bandwidths to the predictable flow and the non-predictable flow to obtain a bandwidth allocation result, and sending the bandwidth allocation result and the scheduling policy to the host, so that the host executes the scheduling policy in a scheduling period. This can prevent congestion in advance and reduce a delay of a delay-sensitive flow, and is applicable to a large data center.

The Ethernet packet may include a first address scheme comprising a destination address (DA) field, and a source address (SA) of the Ethernet packet. The Ethernet packet may be encapsulated in a second Ethernet packet comprising second address scheme. The second Ethernet packet may be encapsulated in an IEEE 802.11 frame comprising a third address scheme.

  • Patent number: 11388136
    Abstract: Methods, systems and computer program products for distributed computing systems. Techniques for dynamic service location discovery operate in environments having a first computing system that hosts a client and a second computing system that hosts a service. A service discovery request is transmitted from the first computing system to access a service that is hosted at the second computing system. An IP address corresponding a next IP hop on a route to the IP address of the service is resolved. After traversing the next IP hop, the second computing system that hosts the service receives the service discovery request and responds with an IP address of the service. In accordance with these techniques, the determination of the IP address of the service is performed at a computing system that is different from the first computing system.

  • Patent number: 11388734
    Abstract: Method for receiving data packet transmissions, wherein synchronization with a transmitter is accomplished based on detection of a preamble transmitted by the transmitter. A time multiplexing scheduling of a single hardware receiver arrangement is used, and the time multiplexing scheduling has a main time slot comprising a first listen period and a second listen period following the first listen period. In the first listen period a first type of synchronization detection is executed (e.g. IEEE 802.15.4), and in the second listen period a second type of synchronization detection different from the first type of synchronization detection is executed (e.g. BLE).

  • Patent number: 11368347
    Abstract: In a broadband wireless communication system, a spread spectrum signal is intentionally overlapped with an OFDM signal, in a time domain, a frequency domain, or both. The OFDM signal, which inherently has a high spectral efficiency, is used for carrying broadband data or control information. The spread spectrum signal, which is designed to have a high spread gain for overcoming severe interference, is used for facilitating system functions such as initial random access, channel probing, or short messaging. Methods and techniques are devised to ensure that the mutual interference between the overlapped signals is minimized to have insignificant impact on either signal and that both signals are detectable with expected performance by a receiver.
