Abstract
Techniques for employing QCL (Quasi Co-Location) signaling for beamforming management are discussed. One example embodiment can comprise a baseband processor of a User Equipment (UE). The baseband processor comprises one or more processors to make a determination whether a first set of RS (Reference Signal) APs (Antenna Ports) are QCL-ed (Quasi Co-Located) with a second set of RS APs with respect to one or more large-scale channel properties and to select a set of receiving parameters for the second set of RS APs based on the one or more spatial receiver parameters. The one or more large-scale channel properties comprise one or more spatial receiver parameters. The first set of RS APs are distinct from the second set of RS APs.

A baseband processor of a User Equipment (UE), comprising:
- one or more processors configured to:
- make a determination whether a first set of RS (Reference Signal) APs (Antenna Ports) are QCL-ed (Quasi Co-Located) with a second set of RS APs with respect to one or more large-scale channel properties, wherein the one or more large-scale channel properties comprise one or more spatial receiver parameters, and wherein the first set of RS APs are distinct from the second set of RS APs;
- and
- select a set of receiving parameters for the second set of RS APs based on the one or more spatial receiver parameters.
A baseband processor configured to be employed within a User Equipment (UE), comprising:
- one or more processors configured to:
- receive QCL (Quasi Co-Location) signaling that indicates a type of QCL between a first set of RS (Reference Signal) APs (Antenna Ports) and a second set of RS APs;
- and
- make a determination based on the indicated type of QCL that whether the first set of RS APs and the second set of RS APs are QCL-ed (Quasi Co-Located) with respect to one or more large-scale channel properties, wherein the one or more large-scale channel properties comprise one or more spatial receiver parameters;
- and
- select a set of receiving parameters for the second set of RS APs based on the type of QCL.
A baseband processor configured to be employed within a base station, comprising:
- one or more processors configured to:
- generate QCL (Quasi Co-Location) signaling, wherein the QCL signaling indicates whether a first set of RS (Reference Signal) APs (Antenna Ports) associated with a User Equipment (UE) and a distinct second set of RS APs associated with the UE are QCL-ed (Quasi Co-Located) with respect to one or more large-scale channel properties, wherein the one or more large-scale channel properties comprise one or more spatial receiver parameters;
- and
- transmit the QCL signaling to the UE.
