  • Patent number: 11375558
    Abstract: Techniques discussed herein can facilitate acknowledgment and/or re-ordering of LWIPEP (LWIP (LTE (Long Term Evolution)/WLAN (Wireless Local Area Network) Radio Level Integration Using IPSec (Internet Protocol Security) Tunnel) Encapsulation Protocol) packets. In various aspects employing a LWIP acknowledgment mode, LWIPEP packets can comprise an enhanced GRE (Generic Routing Encapsulation) header comprising a SN (Sequence Number) of the payload of that LWIPEP packet, which can facilitate acknowledgment of LWIPEP packets and re-ordering of LWIPEP packets (e.g., communicated over a WLAN link, an LTE link, or both) based on the SN(s) indicated in the enhanced GRE header(s).

  • Patent number: 11362858
    Abstract: The invention relates to a method for transmitting data via a communications channel (106), in which the data is transmitted with a transmission frame, wherein the transmission frame has at least one prioritisation field (PCP) for establishing the priority of the message and a data field, wherein the prioritisation field (PCP) functions to control the bus access by prioritising the messages. For this purpose, a bus access controller is used, in which the priority of at least the last received data packet is stored in a minimum priority storage cell (330). After receiving a data packet, a timer (320) is started, for which a timeout value is set, which is reset when a following packet is received. After reaching the timeout value, a decrementing of the value stored in the minimum priority storage cell (330) occurs.

  • Patent number: 11156979
    Abstract: A novel and useful acknowledgement and adaptive frequency hopping mechanism for use in wireless communication systems such as IO-Link Wireless. One or two additional acknowledgement bits are added to packet transmissions. One is a current acknowledgment bit which indicates whether a packet was successfully received anytime during the current cycle. The second bit is a previous acknowledgment bit which indicates whether packets were received successfully anytime during the previous cycle. An adaptive hopping table is constructed using a greedy algorithm which chooses frequencies with the best PER for transmission of higher priority packets, while equalizing the PER products across cycles. A last resort frequency mechanism further improves transmission success by switching to a better performing channel for the last subcycle when previous attempts to transmit a high priority packet have failed.

  • Patent number: 11160100
    Abstract: Multiplexing of information may be useful in a variety of communication scenarios, such as communication of control information. For example, certain wireless communication systems may benefit from uplink control information multiplexing for downlink two orthogonal frequency division multiplexed symbol short transmission time interval and one millisecond transmission time interval. A method can include receiving, at a user equipment, a downlink assignment scheduling first downlink data transmission in a first transmission time interval duration. The method can also include determining when to provide acknowledgment feedback in an uplink corresponding to the scheduled downlink data transmission. The determination can take into account whether the user equipment is scheduled for downlink data transmission in a second transmission time interval duration. The second transmission time interval duration can be shorter than the first transmission time interval duration.

  • Patent number: 11160133
    Abstract: During operation, a radio node may provide, at a transmit time during a first time interval, a first instance of a keep-alive message to a computer. Then, the radio node may receive, at a receive time prior to a first instance of a transmit expire time, an instance of a keep-alive response from the computer, where the instance of the keep-alive response authorizes the radio node to transmit in a granted portion of the spectrum until a second instance of the transmit expire time has elapsed. Moreover, the radio node may determine, based at least in part on the receive time and the first instance of the transmit expire time, an updated transmit time. Next, the radio node may provide, at the updated transmit time, which is prior to the second instance of the transmit expire time, a second instance of the keep-alive message addressed to the computer.

  • Patent number: 11159455
    Abstract: Ingress packet processors in a device receive network packets from ingress ports. A crossbar in the device receives, from the ingress packet processors, packet data of the packets and transmits information about the packet data to a plurality of traffic managers in the device. Each traffic manager computes a total amount of packet data to be written to buffers across the plurality of traffic managers, where each traffic manager manages one or more buffers that store packet data. Each traffic manager compares the total amount of packet data to one or more threshold values. Upon determining that the total amount of packet data is equal to or greater than a threshold value, each traffic manager drops a portion of the packet data, and writes a remaining portion of the packet data to the buffers managed by the traffic manager.
