Systems and methods to provide flow control for mobile devices

摘要

Systems, methods, and apparatuses are disclosed to facilitate wireless communications. User equipment (UE), such as a mobile device, identifies data congestion and transmits a recommended data rate modification wireless signal (e.g., a recommended reduced data rate) to the base station that is transmitting data to the UE. The base station may reduce the data rate of the down link (DL) to the reduced data rate. The UE may then receive data from the base station at the reduced data rate. Therefore, flow control may be implemented at the base station side (e.g., sometimes referred to as the Network (NW) side) based upon the reduced data rate modification determined and transmitted by the UE to the base station. In this way, the data rate transmission to the UE can be reduced to allow the UE to successfully process received data and successfully perform its functions.

主权项

1. A user communications apparatus operable in a wireless communication system, the user communications apparatus comprising:
a processor; a memory in electronic communication with the processor; and instructions stored in the memory and operable, when executed by the processor, to cause the user communications apparatus to: receive data from a base station via a downlink at a data rate; identify data congestion at the user communications apparatus, wherein the data congestion is based at least in part on an ability of the user communications apparatus to process data received at the data rate for the downlink; determine, by the user communications apparatus, a reduced data rate for the downlink and a time period for using the reduced data rate based at least in part on the identified data congestion; transmit, to the base station, a wireless signal comprising a medium access control control element that indicates the reduced data rate, wherein the medium access control control element comprises a flow control timer value that indicates the time period for using the reduced data rate for the downlink; and receive data from the base station via the downlink at the reduced data rate.
