  • Patent number: 11950252
    Abstract: Methods, systems, and devices for wireless communications are described in which repetitions of communications may be configured for multi-transport block (TB) communications. A UE may determine that an acknowledgment of one or more initial repetitions of one or more TBs is received, and may cancel one or more subsequent repetitions of the acknowledged TB(s). The acknowledgment of the one or more initial repetitions may be provided by a base station in a new resource grant that provides an implicit acknowledgment of one or more TBs. In cases where multiple different TBs may be associated with the prior resource grant, the UE can determine to drop one or more repetitions after an implicit acknowledgment of a TB based on whether the resource grants are for a single TB or are for multiple TBs.

  • Patent number: 11950134
    Abstract: The present disclosure discloses a method and a device in communication nodes for wireless communications. In a first node, a successful transmission of a first packet is acknowledged by a first entity, the first entity being used for unicast; a second entity being used for non-unicast does not indicate that the second entity deletes a duplicated first packet; the second entity being used for unicast indicates that the second entity deletes a duplicated first packet; herein, the first entity and the second entity are associated with a same higher layer entity. The present disclosure helps avoid deleting a same packet repeatedly transmitted through multicast, thus ensuring the continuity of traffics received by multicast, which further reduces higher layer retransmissions triggered by deletion of the packet, thus decreasing traffic delay.

  • Patent number: 11916791
    Abstract: Techniques for modifying data packet transmission strategies for a data packet transmitted through a network are disclosed. A node identifies a TCP stage of a data packet flow associated with a data packet received by the node. The node identifies additional characteristics associated with the data packet, such as a duration of the data packet flow to which the data packet belongs. The node modifies a transmission strategy of the data packet based on the TCP stage associated with the data packet and one or more additional characteristics of the data packet. The node modifies the transmission strategy for the data packet by increasing an aggressiveness of the transmission strategy or decreasing the aggressiveness of the transmission strategy. A more aggressive transmission strategy employs more proactive data packet acceleration techniques than a less aggressive transmission strategy.

  • Patent number: 11831717
    Abstract: A low-power wide area network supports IP communication between a wireless device and an IP application node. The LPWAN server provides the application node's IP address and a compression/decompression protocol to the device, which applies the protocol (i) to generate a compressed uplink IP header for wireless transmission to LPWAN radio gateway(s), where the compressed IP header is subsequently decompressed to form an uplink IP packet for transmission to the application node and (ii) to decompress a compressed downlink IP header received from a radio gateway, where the compressed IP header was generated from an uncompressed downlink IP header from the IP application node. The device can also segment large uplink IP packets and reassemble large downlink IP packets. In a LoRaWAN network, the join server facilitates arriving at a common compression/decompression protocol and assigns an IP address to the device to enable IP communication with an IP application client.
