Embodiment Construction

[0033] The present teachings relate to a technique for generating at least one beamforming vector for radio transmission to or for radio reception from at least one target wireless device when generating the at least one beamforming vector Consider the accuracy of the available channel state information (CSI) of the wireless device. Many advantages are gained by taking into account the CSI accuracy, as will be apparent from the description below.

[0034] Typically based on the wireless device's CSI, such as a channel coefficient vector h describing the complex channel gain between a transmitter antenna element and at least one receiver antenna element, a channel coefficient vector h for use to or from one or more target wireless devices is generated. Beamforming vectors for radio transmissions of target wireless devices. However, the CSI available for use in beamforming may have varying accuracy, ie, some elements of the CSI may be out of date or associated with large measur...

Abstract

A method performed in a network node to generate at least one beamforming vector for radio transmission to or radio reception from at least one target wireless device. The method includes obtaining corresponding channel state information CSI and CSI accuracy values ​​for one or more wireless devices. The method also includes generating at least one beamforming vector based on the CSI and a corresponding CSI accuracy value, wherein CSI associated with a high CSI accuracy value is more accurate when generated than CSI associated with a lower CSI accuracy value. CSIs associated with degree values ​​are given equal or higher preference.

Description

technical field [0001] The present disclosure relates to wireless communication networks, and in particular to network nodes and wireless devices for channel state information (CSI) accuracy aware network processing. Background technique [0002] Mobile data traffic in wireless networks is growing due to, for example, the use of smartphones, tablets, and other data traffic heavy equipment. Therefore, operators are constantly striving to increase network capacity and data throughput to meet the growing demand for network throughput. [0003] One way to increase capacity or throughput in a wireless network is to increase the available frequency bandwidth of the system. However, the available spectrum is becoming scarce, requiring an alternative solution to meet the high demands on data rate and throughput. [0004] Another way to handle increased data traffic is not to rely on increased frequency bandwidth, but to deploy more base stations (BS), ie to increase network densit...
