Patent ID: 8854999

Claim:
Method in a user equipment for assisting a base station in scheduling radio resources, the base station and the user equipment are comprised within a wireless communication system, the user equipment comprising a buffer arranged to buffer frames comprising data, the user equipment is arranged to send a scheduling request to the base station at certain dedicated moments in time, which are separated by a predetermined time interval and to send data after having sent a scheduling request and being scheduled radio resources by the base station, the method comprising the steps of: detecting when a frame of data is stored in the buffer; sending a scheduling request to the base station; computing a time offset value based on a time difference between timing when the frame of data was stored in the buffer and timing when the scheduling request was sent; sending the computed time offset value to the base station; and receiving a radio resource grant that is responsive to a predicted buffer state of the buffer of the user equipment, wherein the predicted buffer state comprises either a talk state or a silence state for a voice service.
