Abstract: Methods for processing a raw Internet Protocol (IP) packet and corresponding devices are provided.

Abstract: Disclosed are a method and device for generating a predicted picture, the method comprising: determining a reference rectangular block of pixels according to parameter information which includes a location of a target rectangular block of pixels and/or depth information of a reference view; mapping the reference rectangular block of pixels to a target view according to the depth information of the reference view to obtain a projection rectangular block of pixels; and acquiring a predicted picture block from the projection rectangular block of pixels. The technical problem of relatively large dependence among the data brought by simultaneously employing the depth picture of the target view and the depth picture of the reference view in the process of generating the predicted picture in the prior art is solved, and the technical effects of reducing the dependence on the data and improving the encoding and decoding efficiency is achieved.

Abstract: The method includes that: a first transmission node receives a signal including a Transmission Block (TB) from a second transmission node; the first transmission node obtains states of the P CB sets according to the signal including the TB; the first transmission node determines at least one kind of feedback information in a preset feedback information set according to the states of the P CB sets; and the first transmission node sends the determined feedback information to the second transmission node.

Abstract: Provided are a method and device for processing a network access, and a network access method and device. The processing method includes: acquiring resource configuration information of an access signal group, the resource configuration information including: a sending resource required by a terminal for sending an access signal on a resource corresponding to the access signal group, and an access response resource corresponding to the access signal group, the access signal being used for accessing a network, the access response resource being used for indicating a resource used by a sending device of the access signal when receiving a response signal of the access signal; and notifying the terminal of the resource configuration information.

Abstract: The disclosure discloses an authentication method and system for a wireless mesh network. The method comprises: when a new node accesses a network and the node is a Mesh Point (MP), the MP selects one authenticated node from neighbor nodes as a father node, and a uniquely identified secure path exists between the father node and an AC; the MP uses the father node as an authentication point to perform authentication; and after being transmitted to the AC through the secure path between the father node and the AC, which then forwards an authentication message to an AS; similarly, a return message of the AS is forwarded by the AC to the father node through the secure path, and the MP is authenticated. The authentication message is saved on the AC at the same time, so as to facilitate the second authentication of the MP.
