Disclosed herein is a wireless mesh network comprised of ultra-high-capacity nodes that are capable of establishing ultra-high-capacity links (e.g., point-to-point or point-to-multipoint bi-directional communication links) using a millimeter wave spectrum, including but not limited to 28 Ghz, 39 Ghz, 37/42 Ghz, 60 Ghz (including V band), or E-band frequencies, as examples. The higher capacity and/or extended range of these ultra-high-capacity nodes/links may be achieved via various advanced signal processing techniques. Further, these ultra-high-capacity nodes/links may be used in conjunction with other types of point-to-point and/or point-to-multipoint links to build a multi-layer wireless mesh network.

A mobile cellular network (MCN) communication system can provide an independent mobile cellular network to devices within a covered area. In addition, the MCN communication system can communicate with other MCN communication systems using a wireless standard that is similar to the wireless standard used to communicate with user equipment within the covered area. In some instances, the MCN communication system can be registered as a user equipment of another MCN communication system and/or have another MCN communication system registered with it as a user equipment.

A method and an apparatus for receiving a common public radio interface (CPRI) data stream, a method and an apparatus for receiving an Ethernet frame, and a system, where a first network apparatus receives a first CPRI data stream using a CPRI of the first network apparatus, where the first network apparatus generates a segment of the first CPRI data stream according to the first CPRI data stream, the first network apparatus generates an Ethernet frame, where the Ethernet frame includes the segment of the first CPRI data stream and a CPRI data identifier, and the CPRI data identifier indicates that the Ethernet frame carries CPRI data, and the first network apparatus sends the Ethernet frame to a second network apparatus using an Ethernet interface of the first network apparatus.

A method and device for data synchronization are provided. The method includes that: signalling and/or a forwarded packet are/is sent to M+N slave Transmission Points (TPs); and downlink data synchronization is performed with the slave TPs by sending the signalling and/or the forwarded packet, wherein M slave TPs perform Packet Data Convergence Protocol (PDCP) layer data synchronization with the master TP, N slave TPs may perform PDCP/Radio Link Control (RLC)/Medium Access Control (MAC) layer data synchronization with the master TP, M>=0, N>=0 and M+N>=1.

Embodiments of the present invention relate to a radio resource control RRC message processing method, apparatus, and system. The method includes: setting up, by a first serving node, a connection to a first anchor node, and setting up, by the first anchor node, a connection to a mobility management entity MME; receiving, by the first serving node, a radio resource control RRC message sent by first user equipment UE, where the RRC message includes an RRC message carried by a signaling radio bearer SRB1 or an RRC message carried by an SRB2; and sending, by the first serving node, the RRC message to the first anchor node.

A user equipment (UE) determines that a first transmission or first reception of a first sidelink transmission comprising inter-UE coordination information will overlap in time with a second reception or a second transmission of a second sidelink transmission. The UE transmits or receives a higher priority sidelink transmission among the first sidelink transmission comprising the inter-UE coordination information and the second sidelink transmission.

A distributed Multiple-Input Multiple-Output system comprises one or more antenna units. Each antenna unit comprises at least one antenna element and at least one Antenna Processing Unit (APU) connected to the antenna element. The APU in the one or more antenna units is configurable such that at least one APU in the one or more antenna units is assigned to service as over-the-air interconnects based on load situation and processing power resource of the APU.

The present disclosure relates to methods and apparatus for controlling wireless backhaul link. In one example method, a first device determines to manage a first radio link control (RLC) bearer on a wireless backhaul link between a first backhaul node and a second device, where the second device is a parent node of the first backhaul node, the first device is a centralized unit (CU) of a donor base station, and the second device is a distributed unit (DU) of the donor base station; the second device is a second backhaul node, and the first device is a donor base station; or the first device is a CU of a donor base station, and the second device is a second backhaul node. The first device sends a backhaul type indicator and management information of the first RLC bearer to the first backhaul node.
