摘要： An event regarding control of a terminal that significantly affects communication quality with which communication between the terminal and an external communication device is performed is predicted by acquiring surrounding information of the terminal using a surrounding environment information collection unit, and a packet loss caused in communication, communication disconnection, and communication quality that does not meet required performance are prevented using communication control to change setting related to communication, such as selection/addition/deletion of a communication counterpart, selection/change of a communication scheme, a change in modulation scheme, coding rate, and number of spatial multiplexings of communication, and a change in setting of an automatic gain controller of a receiver for communication.

摘要： A device may determine whether to utilize perfect channel state information at transmitter (CSIT) or imperfect CSIT, and may calculate, based on determining to utilize the perfect CSIT, a first power allocation, a first rate allocation, and a first precoder allocation for a private stream of a user device. The device may determine first parameters or second parameters for the first power allocation, the first rate allocation, and the first precoder allocation, and may generate a first transmit signal and a first data allocation based on the first power allocation, the first rate allocation, the first precoder allocation, and the first parameters or the second parameters. The device may provide the first transmit signal, with the first data allocation, to the user device via the private stream.

摘要： Provided is a communication requirement generation system capable of easily generating a communication requirement. The communication requirement generation system includes a storage unit that stores definition information for calculating a logical distance between components that perform communication in a predetermined network, a determining unit that calculate, for each of a plurality of communication requirements related to the component connected to the network, a logical distance between the component and a component which is a communication partner of the component based on the definition information stored in the storage unit, and determines, based on the calculated distance, whether each of the communication requirements is a communication requirement that requires confirmation of an operator of the network, and an output unit that outputs the communication requirement determined by the determining unit when the communication requirement is the communication requirement that requires confirmation of the operator of the network.

摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are received. A number of padding bits are added to the information bits. The number of padding bits is determined based on respective virtual values of each of one or more encoding parameters. The information bits are parsed to a number of encoders and are encoded, using the number of encoders, to generate coded bits. The coded bits are padded such that padded coded bits correspond to respective true values of each of the one or more encoding parameters. The PHY data unit is generated to include the padded coded bits.

摘要： Techniques for improved wireless configuration are provided. One or more enclosing polygons of a deployment of access points (APs) are determined, and a first query for a regulatory database is generated based on the one or more enclosing polygons, where the regulatory database is spatially-indexed. In response to the first query, a set of spatial regions is received, where each spatial region in the set of spatial regions is associated with a corresponding set of wireless parameters. A first set of wireless parameters is determined, for at least a first AP in the deployment of APs, based on the set of spatial regions. The first AP is configured based on the first set of wireless parameters.

摘要： A method and device for detecting the reachability of a terminal previously served by a first access device of a registration area of a communication network. The first access device is unable to manage sleep and waking periods of the terminal. The terminal is then served by a second device of the registration area, which is able to manage the periods. The method is implemented by a management entity of the network, which has not been informed of the change of access device. The method includes: exchanging messages with the terminal for registration and negotiation of the sleep and waking periods of the terminal; obtaining an item of information relating to data to be transmitted to the terminal; and sending a contact-establishment request message to the terminal during a determined waking period of the terminal.

摘要： A method can include, by operation of a wireless device, monitoring at least a first advertising channel for an advertising packet; in response to advertising data in the advertising packet, synchronizing transmission and reception of packets to an advertising link that includes sub-intervals within a repeating interval on a second advertising channel. During a download sub-interval of the sub-intervals, and update packet can be received that includes new parameter data. During an upload sub-interval of the sub-intervals, transmitting an update response packet indicating the new parameter data has been received. Wireless operations of the wireless device can be configured according to the new parameter data. Communications can continue with the same advertising link while operating according to the new parameter data. Corresponding devices and systems are also disclosed.
