Abstract: A multicast method, apparatus, and system for a software-defined network are presented, where the method includes creating, by a multicast sending device, a multicast group; managing, by the multicast sending device, a member of the multicast group; and completing, by a multicast routing tree management service module disposed on the multicast sending device or on a SDN controller, planning of a multicast routing tree, and converting the planning of the multicast routing tree into a flow entry modification instruction that can be executed by the SDN controller, so that the SDN controller executes the flow entry modification instruction and instructs an SDN switch using a southbound API to execute, according to a modified flow entry, a multicast task. Therefore, multicast is completed by means of mutual cooperation between the multicast sending device and the SDN network.

Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

Abstract: The present disclosure provides an access node configured for determining at least one beamforming parameter for communication between the access node and a user node. The access node including: a first-band receiver configured to receive at least one first signal from said user node on a first frequency band; a processor and a non-transitory computer-readable medium including computer-executable instructions executed by the processor to perform, on the access node, determining at least one first beamforming parameter based on said received first signal; and a second-band transmitter configured to send, with a transmit beam that is configured based on said determined first beamforming parameter, on a second frequency band at least one second signal to said user node. The first frequency band includes lower frequencies than the second frequency band.

Abstract: The present invention relates to a method and equipment for adaptively tracking a mobile terminal with millimeter wave radio link by establishing and/or maintaining a link between an access point or base station and a moving terminal where the method comprises changing the arrangement of the transmission directional beams of an access point or base station and the reception directional beams of a mobile terminal in a channel estimation process responsive to motion characteristics of the access point or base station transmitter or the mobile terminal receiver or both the access point or base station transmitter and the mobile terminal receiver. The invention further relates to a corresponding system and an access point or base station and a movable terminal provided with means for implementing the above method.

Abstract: Webpage loading methods and devices include, in addition to sending an address of a first webpage to a server, a client further sends a name of a first-webpage resource stored in the client, such that the server can determine, according to the address of the first webpage and the name of the first-webpage resource stored in the client, a first push resource to be sent to the client, where the first push resource is all the resources required for loading the first webpage apart from the first-webpage resource stored in the client, which avoids pushing, by the server to the client, a resource that has been locally stored in the client, and therefore saves a bandwidth resource of a communications network.
