Methods and system for managing uplink buffer at user equipment in tethered call mode

Abstract

Wireless communications systems and methods related to uplink buffer management are provided. In some aspects, a user equipment receives a synchronization acknowledgment message destined for a device tethered to the user equipment and transmitted by an application server at a network to which the user equipment is connected. In some aspects, the synchronization acknowledgment message includes an application server receiver window size indicating available buffer space in a receive buffer of the application server. The user equipment can modify the application server receiver window size in the received synchronization acknowledgment message prior to transmitting the received synchronization acknowledgment to the tethered device.

What is claimed is: 
     
         1 . A method of wireless communication performed by a user equipment (UE), the method comprising:
 receiving, from a first wireless communication device, a packet destined for a second wireless communication device; and   modifying the packet to indicate that a buffer of the first wireless communication device is full; and   transmitting the packet to the second wireless communication device.
