Abstract:
Embodiments of the present invention disclose a configuration method, device and system for picocells, and they relate to mobile communication technology field. The method comprises that a first service request message is sent to a first target macro base station, wherein the first target macro base station has the function of beam forming virtual multilayer network structures, the first service request message is used to request the first target macro base station for beam coverage , and the identification (ID) information of the macro base station sending the service request message and the location information of the appointed region needing beam coverage are included in the first service request message; after the first target macro base station providing beam coverage for the appointed region, a user in the appointed region can communicate using the beam coverage. It is mainly used in configuration of picocells.
Abstract:
Disclosed is a digital interference cancellation apparatus, comprising: a first interference cancellation module which receives a digital transmitting signal output by a transceiver as a digital baseband reference signal, wherein the digital baseband reference signal is used to reconstruct a first self-interference signal, and a digital receiving signal received from the transceiver minus the first self-interference signal results in a digital receiving signal after first level interference cancellation; and a second interference cancellation module which receives a digital transmitting signal output by a transceiver as a digital baseband reference signal, wherein the digital baseband reference signal is used to reconstruct a second self-interference signal, and the digital receiving signal after first level interference cancellation minus the second self-interference signal results in the digital receiving signal after second level interference cancellation. Also disclosed are a digital interference cancellation method, a wireless full duplex system and a transceiver. A self-interference signal in a digital receiving signal can be cancelled effectively in a complicated communication environment by using the embodiments of the present invention.
Abstract:
The embodiments of the present invention relate to a terminal scheduling method, a station and a terminal. The method comprises: a first station sends a first notification message to a first terminal which is also in a first service set, the first notification message being used for instructing the first terminal to send a detection signal; the first station receives mutual interference information sent by a second terminal, wherein the mutual interference information comprises a signal parameter value for representing that signal interference is produced between the second terminal and the first terminal, and identification information for determining the first terminal sending the detection signal, and the mutual interference information is sent if the detection signal is intercepted by the second terminal; and the first station performs scheduling processing on the first terminal and the second terminal according to the signal parameter value and the identification information.
Abstract:
There is disclosed a technology to provide a signaling-transmission managing method or the like which is capable of continuing a link of a network, even if the link goes down, reducing burdens on a terminal end node, inhibiting wasting of a network resource and reducing burdens on a node between the terminal end node and a node where signaling gathers, and according to the technology, an upstream relay node transmits a first message indicating that the link has been disconnected to a first relay node, the first relay node transmits a second message indicating that information of a state stored in a correction node should be updated to the correction node, the correction node transmits a third message to update the states of relay nodes along a path from the correction node itself to a data reception node, and the relay node which has received a fourth message from the upstream relay node to the data reception node for a correction request of the correction node and the third message transmits a message to update the states of the relay nodes in a case where it is judged based on the messages that the node itself is a new correction node.
Abstract:
A single-sign-on to access multiple networks residing at multiple domains is disclosed. In particular the single-sign-on features refers to the authentication and the authorization process carried out among the different network administration domains so that the terminal using the end service need not explicitly initiate the authentication process each time it accesses a new service. This invention's single-sign-on feature can be extended for usage in a federated domain environment and non-federated domain environment. The non-federated domains are able to form an indirect federation chain through other domains in order to utilize this invention. Therefore discovery of intermediate domains to form a federation chain is also covered. The management of user credentials to allow a Visited Domain to perform authetication is also covered in this invention.
Abstract:
A system for device trigger delivery in a mobile communication network includes a mobile terminal that is capable of responding to an application layer device trigger, an application layer server that is capable of requesting a new connection establishment from the mobile terminal via device trigger, and a network control entity that is capable of delivering the device trigger through two independent domains and deploying congestion control in these two domain independently. When the mobile terminal decides a new domain connection establishment in response to an application layer device trigger from the application layer server is needed, the mobile terminal triggers an inter domain negotiation to facilitate a connection request to transmit the response to the application layer device trigger.
