Samsung patents method to mark unused ports in 5G network hardware
This patent describes a way for a radio unit in a 5G network to recognize when a specific port is not assigned to any user. It works by checking for a special code in a control message from the network's distributed unit, which tells the hardware that a particular resource region is empty.
In the filing’s own words
A radio unit (RU) is provided. The RU includes memory storing instructions, one or more transceivers configured to transmit signals or receive signals on a fronthaul interface, and one or more processors. Wherein the instructions cause, when executed by the one or more processors, the RU to receive, from a distributed unit (DU), a control plane (C-plane) message including section information for user equipment (UE) scheduling information and section extension information for a group configuration of multiple ports, wherein the section information including information on a resource region of a section description and a UE identifier, and the section extension information including information on a beam group type, information on the number of one or more ports indicated by the section extension information, and a UE identifier per port, and, in case that a UE identifier of a specified port is set to 0x7FFF in the C-plane message, identify that the resource region is not allocated for the specified port.
What exactly they claim (claim 1)
1. A method performed by a radio unit (RU), the method comprising: receiving, from a distributed unit (DU), a control plane (C-plane) message comprising section information for user equipment (UE) scheduling information and section extension information for a group configuration of multiple ports, wherein: the section information comprises information on a resource region of a section description and a UE identifier, and the section extension information comprises information on a beam group type, information on the number of one or more ports indicated by the section extension information, and a UE identifier per port; and in case that a UE identifier of a specified port is set to 0x7FFF in the C-plane message, identifying that the resource region is not allocated for the specified port.
