CPC H04B 7/0626 (2013.01) [H04B 7/0478 (2013.01)] | 20 Claims |
1. A host configured to operate in a communication system to provide an over-the-top (OTT) service, the host comprising:
processing circuitry configured to provide user data; and
a network interface configured to initiate transmission of the user data to a network node in a cellular network for transmission to a user equipment (UE), the network node having a communication interface and processing circuitry configured to perform operations comprising:
receiving a channel state information (CSI) report for a downlink channel, the CSI report indicating a plurality of precoder vectors, wherein each of the precoder vectors corresponds to a frequency sub-band of a bandwidth of the downlink channel, a precoder vector being expressed as a linear combination of spatial-domain components and frequency-domain components, wherein each of the spatial-domain components is associated with a respective set of one or more frequency-domain components and wherein a number of frequency-domain components associated with a first spatial-domain component is larger than a number of frequency-domain components associated with a second spatial-domain component, wherein the received CSI report includes an indication of linear combination coefficients for each combination of spatial-domain component and associated frequency-domain components;
determining precoding to use for transmitting data to the UE based at least in part on the CSI report; and
transmitting the user data from the host to the UE according to the determined precoding to provide the OTT service.
