A millimeter-wave repeater may be provided to cover a radio shaded area, in a system for the millimeter-wave repeater. The millimeter-wave repeater may provide a service by changing a signal of a millimeter-wave band to an intermediate frequency band, and then changing the signal to the millimeter-wave band again.

A method according to a first aspect is a method performed by a relay node that establishes a radio backhaul link, with an adjacent relay node, relaying communication between a user equipment and a donor base station. The method includes measuring a parameter related to communication quality of a data packet by a BAP entity that transmits or receives the data packet via the radio backhaul link, and reporting a result of the measuring to the donor base station by an upper entity locating in an upper layer than the BAP entity.

Supporting multi-signal source communications in a distributed communications system (DCS) is disclosed. The DCS includes a routing circuit configured to route downlink and uplink communications signals between multiple signal sources and a number of remote units. In examples disclosed herein, the routing circuit and each of the remote units are functionally divided based on an open radio access network (O-RAN) Split 7.2 configuration. To support downlink communications from multiple signal sources, the routing circuit generates a downlink frequency-domain communications signal, which includes one or more selected logical channels associated with one or more of the multiple signal sources, for each of the remote units in the DCS. Accordingly, each remote unit converts the downlink frequency-domain communications signal into a downlink time-domain communications signal for transmission in a downlink radio frequency (RF) communications signal. As such, it may be possible to improve scalability while reducing cost and space of the DCS.

A relay device includes: a storage unit storing a correspondence table that correlates header information with a relay resource, the relay resource implementing a communication request class defined based on the header information; a data acquisition unit acquiring the data transmitted from the transmission source device as acquired data; a relay resource determination unit determining a relay resource for the acquired data based on header information included in the acquired data and the correspondence table; and a data transmission unit transmitting the acquired data to the destination device using the relay resource determined by the relay resource determination unit.

A repeater system includes a first repeater device to receive a first beam of radio frequency (RF) signal from a first network node, and a second repeater device to receive a second beam of RF signal from the first network node.

A plurality of signal parameters is selected at the first and second repeater devices for a first beam and a second beam of RF signal, respectively. The first repeater device establishes an additional link with the second repeater device, where based on the additional link, a first data stream carried by the first beam of RF signal is provided to the second network node through the first repeater device as well as the second repeater device.
