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 shared spectrum manager (SSM) may enable spectrum access for Tier 2 Users (T2Us) and Tier 3 Users (T3Us) while provisioning quality of access (QoA) in a dynamic shared spectrum environment while ensuring sufficient spectrum and interference protection for Tier 1 Users (T1Us). The SSM may enable new user spectrum authorizations by sending, to a regulator, a request for administrative information, and receiving, from the regulator, a policy and user authorization information for at least one user. The SSM may register a T2U with or without contacting the regulator. The SSM may perform quality based admission control by receiving periodic measurements from a master device of each T2U with an active frequency assignment indicating a Quality of Operation (QoO) experienced by the respective T2U, maintaining a map of an effective QoOs for a plurality of T2Us, and categorizing protection contours associated with each of the plurality of T2Us.

This application relates to the field of communications technologies, and more specifically, to a technology for establishing an operation and management channel. In a channel establishment method, a base station obtains a connection status of an operation and management channel between a base station and an operation support system OSS server. If the connection status indicates that there is a connection exception on the operation and management channel, the base station obtains a historical channel establishment parameter that is stored in the base station before a current moment and that is used by the base station to establish the operation and management channel with the OSS server.

Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

A synchronization method, a communication handover method, a radio network, and a RAN node are disclosed. The interface information synchronization method includes determining whether a condition for initiating interface information update is fulfilled. Information about the S1 interface between the RAN node and the core network node, is sent. In addition, or alternatively, information about the X2 interface between the RAN node and the neighboring RAN node is sent to the neighboring RAN node if the condition for initiating interface information update fulfilled.

Wireless communications for paging assistance are described. Paging assistance information may comprise one or more beam parameters to provide beam-based paging for a wireless device. One or more devices may use beam-based paging to reduce usage of wireless resources.

Embodiments of the present invention relate to a radio self-backhaul method, device, and system in an evolved network. With the radio self-backhaul method, device, and system provided in the embodiments of the present invention, the NodeB sends the uplink data to the core network by using the cable transmission link without occupying the radio resources of other NodeBs. This implements the radio self-backhaul for the NodeB, saves the radio transmission resources of the NodeB, and mitigates the impact on the radio network throughput.

A mobile receiving vehicle may be directed to cover an area to maximize the communication opportunities for mobile computing devices. The demands on the mobile receiving vehicles may change over time and the mobile receiving vehicles may move according to a plan to maximize network access.

A layer 2 processing method, a CU and a DU are provided. The layer 2 processing method includes: sending channel reconstruction indication information to the DU; receiving a response message sent by the DU; generating an RRC reconfiguration message based on the response message; and sending the RRC reconfiguration message to a UE, and performing, by the UE, a corresponding operation.

A communication system that may be used in room and building automation. A mesh network may be associated with a room of a building, or the like. Connectivity may be provided for devices with servers and a cloud in one mode. Connectivity may be provided for devices to mobile devices and a room-level information module in another mode. These modes of connectivities of various modes may be effected with a software definable radio or radios. Other modes of connectivity may be implemented. Examples of modes may incorporate Bluetooth low energy (BLE) and non-BLE formats. The modes may be multiplexed to operate one at a time and be switched back and forth as needed.
