  • Publication number: 20220385437
    Abstract: This disclosure provides methods, devices and systems for wireless communications over a 320 MHz bandwidth. Some implementations more specifically relate to signaling techniques for indicating the bandwidth of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmitted in a secondary 160 MHz channel of the 320 MHz bandwidth. In some implementations, an access point (AP) may transmit an aggregated PPDU (A-PPDU) that includes a first sub-PPDU transmitted within a primary 160 MHz channel and a second sub-PPDU transmitted within a secondary 160 MHz channel. In such implementations, the first sub-PPDU may carry bandwidth information indicating the bandwidth of the first sub-PPDU within the primary 160 MHz channel and the second sub-PPDU may carry bandwidth information indicating the 320 MHz bandwidth.

  • Patent number: 11496924
    Abstract: This disclosure provides methods, devices and systems of wireless communication in accordance with hybrid automatic repeat request (HARQ) techniques. Some implementations more specifically relate to aligning aggregate medium access control (MAC) protocol data unit (A-MPDU) subframes with codeword boundaries in a physical-layer service data unit (PSDU). The alignment may be performed by selectively adding padding bits to the PSDU based on the size of each A-MPDU subframe and the lengths of the codewords. In some aspects, an A-MPDU subframe may be aligned with a first codeword of the PSDU so that the first A-MPDU subframe is encoded exclusively within the first codeword. In some other aspects, an A-MPDU subframe may be aligned with two or more contiguous codewords of the PSDU so that the two or more contiguous codewords include the A-MPDU subframe and no portions of any other A-MPDU subframe.

  • Patent number: 11469859
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol may be based on a hybrid automatic repeat request (HARQ) protocol that supports a delayed acknowledgement for a HARQ retransmission based on receiver processing capability. A first WLAN device may determine that a second WLAN device requires more time to process the HARQ retransmission and may transmit a different communication (interlaced within the HARQ process) to either the second WLAN device or a third WLAN device during the time that the second WLAN device is processing the HARQ retransmission.

  • Patent number: 11460903
    Abstract: A power consumption optimization system includes a virtual machine (VM) provisioned on a host, a memory, a server, and a processor in communication with the memory. The processor causes the server to store a power consumption profile of the VM. The VM runs at a processor frequency state. Additionally, the processor causes the server to receive a request to lower a processor frequency for the VM from an original processor frequency state to a reduced processor frequency state. The request has request criteria indicating a time duration associated with the request. The server validates the request criteria and a requirement of another tenant on the host. Responsive to validating the request criteria and the requirement the other tenant on the host, the server confirms the request to lower the processor frequency. Additionally, the server lowers the processor frequency to the reduced processor frequency state during the time duration.

  • Patent number: 11463374
    Abstract: A system and method for providing high availability for a thin-provisioned container cluster includes a memory, one or more processors in communication with the memory, a scheduler executing on the one or more processors, and a spot instance market monitor. The spot instance market monitor receives market information about spot instances in a cloud system at a first time. The spot instances are available to a client at the first time. The spot instance market monitor determines, based on the market information, a respective reliability value for each of the spot instances at the first time. Then, the scheduler selects one spot instance among the spot instances based on the reliability value of the spot instance. In response to the selection of the spot instance, the scheduler schedules a container on the spot instance and executes the container on the spot instance.
