Problems solved by technology

However, during most of the operating time of the radio base station, the traffic load and demand of the radio base station is not so high, which means that the static energy consumption becomes a major part of the total energy consumption of the radio base station

Embodiment Construction

[0045] Throughout the figures, the same reference numbers are used for similar or corresponding elements.

[0046] The embodiments disclosed herein relate to data communication scheduling by a radio base station in a radio communication network, and in particular such data communication scheduling that enables the reduction of static power consumption of the radio base station.

[0047] Data communication scheduling and the static power consumption it can achieve are achievable in a radio base station serving multiple cells or sectors in a radio communication network. Therefore, a radio base station includes equipment for providing communication services to user equipment existing in different geographic areas or cells served by a single radio base station. figure 1 It is an overview of a part of the radio communication network 1 including such a radio base station 100. In the figure, the radio base station 100 has been exemplified as a radio base station serving any user equipmen...

Abstract

A data communication scheduling system (300) of a radio base station (100) serving multiple cells (10-30) comprises multiple radio equipment, REs, (101-103) and antenna interfaces (115, 125, 135) connectable to antennas (110, 120, 130). In order to reduce the power consumption, only a subset of the RE (101) is active, while the other REs (102, 103) are turned off. A transmitter controller (155) is arranged for controlling the active RE (101) to be shared among multiple cells (10-30) during a radio frame (40) so that each cell (10-30) is guaranteed at least one sub frame (50-58) for downlink transmission. A receiver antenna system multiplexer(140) selectively interconnects the active RE (101) with the antenna interfaces (115, 125, 135) according to the operation of a receiver controller (145). Consequently, the RE (101) becomes connected to different antenna interfaces (115, 125, 135) during different sub frames (50-58) to thereby allow each cell (10-30) at least one assigned uplink sub frame (53-55) in the radio frame (40) at a predefined sub frame distance after the at least one downlink sub frame (50-52) assigned to the same cell (10-30).

Description

Technical field [0001] The present invention generally relates to radio communication technology and operations in radio communication networks, and in particular, to the scheduling of data communication in such radio communication networks. Background technique [0002] In radio communication networks such as the so-called Long Term Evolution (LTE) network, there are one or more network nodes called radio base stations that are arranged to control and schedule travel to and from a geographic area called a cell served by the radio base station. Data services of user equipment. [0003] The radio base station therefore includes, for each such cell, one or more receivers and transmitters or devices in the form of transceivers for realizing wireless data communication. These receivers and transmitters consume considerable energy even if they are not currently transmitting or receiving any data. This energy required to keep the device working is called static energy to distinguish it...
