  • Header compression handling during handover
    Patent number: 11044632
    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, handling header compression in scenarios with concurrent connections, such as make-before-break (MBB) handover or dual connectivity (DC) scenarios. A method of wireless communication performed by a user equipment (UE) can include concurrently communicating with a first base station (BS) on a connection with the first BS and with a second BS on a connection with the second BS during a handover procedure. The UE maintains a context for a header compression protocol for the connection with the first BS and the connection with the second BS. The concurrently communicating includes using the header compression protocol context for sending one or more packets, receiving one or more packets, or both.

  • BUFFER MANAGEMENT TECHNIQUES FOR ENHANCED MULTI-CONNECTIVITY COMMUNICATIONS
    Publication number: 20210185747
    Abstract: Wireless communications systems and methods related to buffer/memory management for multi-connectivity in a wireless communication network are provided. A wireless communication device transmits a first portion of a plurality of data packets using a first radio access technology (RAT). The wireless communication device transmits a second portion of the plurality of data packets using a second RAT different from the first RAT. The wireless communication device stores at least some of the plurality of data packets in a memory pending an acknowledgement (ACK) indication associated with at least a first data packet of the plurality of data packets. The wireless communication device determines a transmission configuration for at least the first data packet and a second data packet based on whether a threshold occupancy of the memory is satisfied. Other aspects and features are also claimed and described.

  • PROCEDURES FOR MANAGING QUALITY OF SERVICE FLOWS
    Publication number: 20210176659
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink data associated with a first quality of service flow is available for transmission to a base station. The UE may transmit a buffer status report to the base station. In some examples, the buffer status report may include a buffer status of the first quality of service flow. The UE may then receive an uplink grant based on transmitting the buffer status report, and may transmit the uplink data based on the uplink grant.

  • HOST DRIVEN MODEM UPLINK PACKET PRIORITIZATION
    Publication number: 20210160187
    Abstract: Methods, systems, and devices for wireless communications are described in which a host processor at a user equipment (UE) may packetize data for uplink transmissions from the UE and provide packets to a wireless modem of the UE for uplink transmission. The host processor may provide multiplexing and aggregation headers for the packets that include a prioritization indication, and the wireless modem may order the data packets for transmission based at least in part on the prioritization indication. In some cases, a priority for each packet is indicated in a priority field of a corresponding multiplexing and aggregation header. The wireless modem may transmit the data packets based on the ordering, to provide higher priority packets ahead of lower priority packets to a receiver. Additionally, data packets may be further ordered based on tuple information associated with the data packets.

    Publication number: 20210112449
    Abstract: The disclosure includes a method at a device configured to process both wireless data traffic and Ethernet data traffic into a wireless communication, comprising determining, at a compressor, whether an acknowledgement (ACK) signal is received from a decompressor in response to transmitting, over a wireless communication link, a context creation message for a context identification (ID) associated with a flow of incoming Ethernet data traffic; refraining from transmitting, by the compressor to the decompressor over the wireless communication link, a compressed packet corresponding to the flow based on a first determination that the ACK signal is not received from the decompressor; and transmitting, by the compressor to the decompressor over the wireless communication link, the compressed packet corresponding to the flow based on a second determination that the ACK signal is received from the decompressor.

  • SYSTEM AND METHOD FOR FLOW CONTROL AND ACKNOWLEDGEMENT TRANSMISSION
    Publication number: 20200404541
    Abstract: A configuration to enable a UE to send data to a modem, from an AP, in the absence of an uplink grant from the modem. An apparatus receives data transmissions from a base station. The apparatus stores the data transmissions in a memory of the AP of the apparatus. The apparatus identifies, by the AP, an uplink grant based at least in part on a size of a modem buffer. The apparatus determines, by the application processor, whether to send data to the modem based at least in part on the identified uplink grant. The apparatus sends, by the AP, the data when the identified uplink grant exceeds a threshold.
