Abstract: Example uplink switching methods and apparatus are described. One example method include performing switching between a supplementary uplink (SUL) and a normal (NUL), where a switching time period for the switching between the SUL and the NUL is longer than 0 microseconds. Therefore, the SUL and the NUL can share a radio frequency channel so that the shared radio frequency channel can be switched between the SUL and the NUL.

Abstract: A first ECU performs an operation using a first key and a first fresh value to generate a keystream; performs an exclusive OR operation using the keystream and a to-be-transmitted first plaintext packet to generate a first ciphertext packet; and sends the first ciphertext packet to a second ECU. The first fresh value is a value generated by a counter in the first ECU when the first ECU transmits a packet, and the counter is configured to record a quantity of packets transmitted by the first ECU. The first ECU transmits the first ciphertext packet to the second ECU. This can prevent the first packet transmitted by the first ECU from being eavesdropped on, and help improve confidentiality of the packet transmitted by the first ECU.

One example method includes inserting, by a transmitter according to pilot mappings corresponding to Nt transmit antenna ports by using Nt orthogonal pilot sequences that are different from each other, a pilot sequence corresponding to each of the transmit antenna ports into OFDM symbols that are included in the pilot mapping corresponding to the transmit antenna port. There is a one-to-one correspondence between the Nt pilot sequences and the Nt transmit antenna ports of the transmitter, where Nt is a positive integer greater than or equal to 2. The pilot mappings corresponding to the transmit antenna ports are the same among the Nt transmit antenna ports.

Abstract: In an example method, a second node receives a pairing request message from a first node. The pairing request message includes information used to indicate whether the first node has a pre-shared key (PSK) pairing capability. The second node sends a pairing response message to the first node in response to that the pairing request message includes information used to indicate that the first node has the PSK pairing capability. The pairing response message is used to indicate to perform pairing by using a shared first PSK. The second node authenticates the first node based on the first PSK.

Abstract: The present disclosure provides example wavelength selective switch (WSS), wavefront control element, and integrated liquid crystal on silicon (LCoS). One example WSS includes an input port fiber array, a demultiplexing/multiplexing grating group, an output port fiber array, and a beam deflection component group including two beam deflection components and at least one wavefront control element located between the demultiplexing/multiplexing grating group and the beam deflection component group or integrated with the LCoS. At least one beam deflection component is a LCoS. The input port fiber array receives multi-wavelength optical signals. The demultiplexing/multiplexing grating group demultiplexes and outputs the multi-wavelength optical signals. The beam deflection component group deflects the multi-wavelength optical signals to the demultiplexing/multiplexing grating group. The demultiplexing/multiplexing grating group multiplexes the multi-wavelength optical signals to the output port fiber array. The wavefront control element and the LCoS jointly modulate optical signals transmitted through N*M wavelength channels.
