Abstract

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may transmit a capability message indicating that the UE can perform a modification procedure on one or more explicit congestion notification (ECN) fields and may receive a configuration message instructing the UE to perform the modification procedure. Thus, when the UE receives data packets that include ECN fields, the UE may modify the ECN field of a first data packet based on receiving the configuration message. In some other examples, the UE may receive the data packets at a modem of the UE via a wireless channel. The UE may then send congestion information associated with the wireless channel from the modem of the UE to a congestion controller of the UE. Using the congestion information the UE may then send a feedback message that is associated with the received data packets.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
transmit a capability message indicating that the UE is capable of performing an explicit congestion notification (ECN) field modification procedure on a data packet;
receive a configuration message instructing the UE to perform the ECN field modification procedure based at least in part on the capability message;
receive, via a first wireless channel, one or more data packets, wherein the one or more data packets comprise respective ECN fields in respective header portions of the one or more data packets;
and
modify an ECN field of a first data packet of the one or more data packets based at least in part on receiving the configuration message.
