Abstract: A channel estimation apparatus and method are provided to ensure that a channel estimation value can correctly reflect a transmission channel status, so that an orthogonal frequency division multiplexing (OFDM)-based wireless system can correctly transmit an aggregate long frame according to the channel estimation value. The channel estimation apparatus determines a first channel estimation value, receives a first symbol group of a long frame according to the first channel estimation value, and determines a second channel estimation value according to the first symbol group, and if a difference between the first channel estimation value and the second channel estimation value is less than or equal to a first threshold, determines a third channel estimation value according to the first channel estimation value and the second channel estimation value.

Abstract: In an uplink service transmission method, an access point divides an entire channel into resource blocks according to a quantity of stations that are connected to the access point, then allocates, to each station according to channel estimation information of each station, a resource block used to transmit uplink information, and separately sends channel allocation indication information to each station, so that each station finds, according to the channel allocation indication information, the resource block corresponding to the station, and transmits the uplink information by using the resource block, so as to implement that in an OFDMA system, multiple stations transmit uplink information in parallel, that is, resource blocks that are obtained by means of division can be simultaneously applicable to multiple stations.

Abstract: A method, an apparatus, and a device are provided for information transmission. In the method, the apparatus determines an initial OFDM symbol in OFDM symbols used to transmit load information. The apparatus determines, starting from the initial OFDM symbol, a phase deviation difference between two adjacent OFDM symbols according to first information to be transmitted. The apparatus performs phase deviation on at least one of the OFDM symbols according to the phase deviation difference. The apparatus then sends the OFDM symbols obtained after the phase deviation to a receiving end.

Abstract: It is possible to reduce the PAPR of an amplified signal communicated over bonded channels by applying different phase shifts to control fields communicated over the bonded channels. The phase shifts reduce the amount of constructive interaction between the control fields by shifting the peaks of the respective signals in the time domain. The control fields may include short training fields (STFs), channel estimation (CE) fields, or header fields communicated over bonded channels.

Abstract: This application provides a communication method and a related apparatus. In this method, a first neural network model may be determined from one or more pre-trained neural network models, the first neural network model is adjusted based on communication resource information and/or channel state information for communication between a first device and a second device, and an adjusted first neural network model is sent, or a submodel in an adjusted first neural network model is sent, where the adjusted first neural network model is used for the communication between the first device and the second device. It can be learned that the neural network model used for the communication between the first device and the second device is obtained through adjustment based on the pre-trained neural network model that has been trained.
