Problems solved by technology

[0017] The current buffer status reporting framework has several disadvantages, such as for example buffer status information may be out of date when used in scheduling decisions
Additionally, buffer status information may only be based on 1-bit scheduling requests when used in scheduling decisions

Abstract

Method and arrangement in base station (110) for estimating the amount of data to be received from a terminal (120). The base station (110) and the terminal (120) are comprised within a wireless communication system (110). The terminal (120) comprises a buffer arranged to buffer frames comprising data. The method comprises determining (401) a service requested by the terminal (120), estimating (403) the arrival time of data to be received from the terminal (120), based on the determined service, and setting (404) a buffer estimate, comprising an estimation of the amount of data to be received, based on an estimated frame size for the determined service.

Description

technical field [0001] The present invention relates to methods and devices in wireless communication systems, and more particularly to mechanisms for improved buffer estimation. Background technique [0002] In the 3rd Generation Partnership Project (3GPP), work is ongoing on the specification of the Evolution of UMTS Terrestrial Radio Access Network (UTRAN) (E-UTRA) as part of the Long Term Evolution (LTE) work. [0003] In LTE, scheduling is modeled in the Medium Access Control (MAC) layer and resides in the eNodeB (eNB). The scheduler assigns radio resources, also called resource blocks (RBs), for the downlink (assignments) and for the uplink (grants) using the Physical Downlink Control Channel (PDCCH). [0004] The radio uplink is the transmission path from a terminal, which may also be called User Equipment (UE), to a base station or eNodeB. The downlink is the opposite of the uplink, ie the transmission path from the eNodeB to the terminal. [0005] For uplink sche...
