| 摘要 | Method and arrangement in a base station for scheduling radio resources to a user equipment. The method and arrangement comprises receiving a scheduling request from the user equipment, and also a time offset value which value is associated with the moment of time when a frame of data was generated in the user equipment buffer. Also, the moment of time when the frame of data was generated in the user equipment buffer is determined, based on the received time offset value. Thereby the buffer state of the user equipment buffer is predicted by using the determined moment of time when the frame of data was generated in the user equipment buffer. Further, radio resources are granted to the user equipment, based on the predicted buffer state of the user equipment buffer. In addition, a method and arrangement in a user equipment for assisting the base station in scheduling radio resources are described. | ||

| 主权项 | 1. 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. | ||
