Abstract:
1. A method in a wireless communication system for scheduling radio resources, the wireless communication system comprising a base station and a user equipment, the user equipment comprising a buffer configured to buffer frames comprising data, and the user equipment-configured to send the frames comprising data after being scheduled resources by the base station, the method comprising: detecting, in the user equipment, when a frame of data is generated in the buffer; computing, in the user equipment, a time offset value based on a time difference between when the frame of data was generated in the buffer and a timing reference; sending, by the user equipment, the computed time offset value to the base station; determining by the base station, when the frame of data was generated in the buffer of the user equipment based on the computed time offset value and the timing reference; predicting, by the base station, a buffer state of the buffer of the user equipment based on when the frame of data was generated in the buffer of the user equipment; and granting, by the base station radio resources to the user equipment, based on the predicted buffer state of the buffer of the user equipment, wherein the timing reference is one of when the generated frame of data is transmitted to the base station, a next scheduling request opportunity and when a scheduling request was sent to the base station.
