Systems and methods for managing transmission control protocol (tcp) acknowledgement (ack) transmissions

A user equipment (UE), comprising:

• a processor configured to:
• detect availability of buffer space in a memory buffer of a modem of the UE;
• detect that a host processor of the UE lacks credit sufficient for transmitting data from the host processor to the modem;
• and
• generate a data flow control (DFC) command including credit sufficient for the host processor to transmit at least a portion of the data to the modem based on an amount of the buffer space;
• and
• a transceiver configured to:
• transmit, from the modem to the host processor, the DFC command;
• and
• receive, by the modem from the host processor, the at least the portion of the data in response to the transmitting the DFC command.

A non-transitory computer-readable medium (CRM) having program code recorded thereon, the program code comprising:

• code for causing a user equipment (UE) to detect availability of buffer space in a memory buffer of a modem of the UE;
• code for causing the UE to detect that a host processor of the UE lacks credit sufficient for transmitting data from the host processor to the modem;
• code for causing the UE to generate a data flow control (DFC) command including credit sufficient for the host processor to transmit at least a portion of the data to the modem based on an amount of the buffer space;
• code for causing the UE to transmit, from the modem to the host processor, the DFC command;
• and
• code for causing the UE to receive, by the modem from the host processor, the at least the portion of the data in response to the transmitting the DFC command.

A user equipment (UE), comprising:

• means for detecting availability of buffer space in a memory buffer of a modem of the UE;
• means for detecting that a host processor of the UE lacks credit sufficient for transmitting data from the host processor to the modem;
• means for generating a data flow control (DEC) command including credit sufficient for the host processor to transmit at least a portion of the data to the modem based on an amount of the buffer space;
• means for transmitting, from the modem to the host processor, the DFC command;
• and
• means for receiving, by the modem from the host processor, the at least the portion of the data in response to the transmitting the DFC command.
