Method and User Equipment for Predicting Available Throughput for Uplink Data

A method performed by a user equipment which is in communication with a base station over a radio link in a wireless communications network, the method comprising:

• obtaining first information about a past uplink scheduling of the user equipment;
• determining an estimated cell load of a cell served by the base station, based on the first information about the past uplink scheduling of the user equipment;
• determining an estimated throughput for uplink data to be sent from the user equipment to the base station over the radio link, based on a relationship between the estimated cell load and a previously obtained cell load;
• and
• optimizing a quality of service based on the estimated throughput.

A user equipment, comprising:

• communication circuitry configured to communicate with a base station a base station over a radio link in a wireless communications network;
• and
• a processor coupled to the communication circuitry, the processor being configured to:
• obtain first information about a past uplink scheduling of the user equipment;
• determine an estimated cell load of a cell served by the base station, based on the first information about the past uplink scheduling of the user equipment;
• determine an estimated throughput for uplink data to be sent from the user equipment to the base station over the radio link, based on a relationship between the estimated cell load and a previously obtained cell load;
• and
• optimize a quality of service based on the estimated throughput.
