Abstract: A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.

Abstract: This application provides a communication method and apparatus, so that a terminal device reports an RLF report related to whether link recovery for an MCG succeeds. The terminal device separately communicates with a first network device and a second network device, where the first network device manages a first MCG, the second network device manages a first SCG, and an MCG link recovery function is configured for the first SCG. After determining that a radio link failure RLF occurs in the first MCG, the terminal device sends a first RLF report to a third network device, where the first RLF report is related to whether link recovery for the first MCG succeeds.

Abstract: A secure communication method includes receiving, by a first network element, first information and a first signature from a network management network element. The first signature is generated based on a private key of the network management network element and the first information, and the first information is used to describe the first network element. The method also includes sending, by the first network element, the first information and the first signature to a certificate issuing network element. The first information is used to obtain a first certificate, and the first certificate is used to prove an identity of the first network element. The method further includes receiving, by the first network element, the first certificate from the certificate issuing network element.

Abstract: Embodiments of this application provide an encoding method and apparatus, to improve an encoding gain in an RCM. The method includes: performing bit mapping on krv1 information source bits whose reliability is lower than a first threshold in a first bit sequence, to obtain a second bit sequence, where the first bit sequence is a bit sequence obtained by performing bit mapping after cyclic redundancy check CRC bits are added to an information source bit sequence, the krv1 information source bits are bits in the information source bit sequence, and a length of the first bit sequence is equal to a length of the second bit sequence; performing an exclusive OR operation on bits in a bit sequence obtained by encoding the first bit sequence and bits in a bit sequence obtained by encoding the second bit sequence, to obtain a third bit sequence; or encoding the second bit sequence, to obtain a third bit sequence; and mapping, to an orthogonal frequency-division multiplexing OFDM symbol, the third bit sequence and the bit sequence obtained by encoding the first bit sequence.

Abstract: A travelling-wave tube includes an input apparatus, a control circuit, an electron gun, a slow-wave circuit, and an output apparatus. The input apparatus may be configured to receive a radio frequency signal, and feed the radio frequency signal into the slow-wave circuit. The control circuit may be configured to determine a quantity N of electron beams and currents of the N electron beams, and control the electron gun to emit the N electron beams. Further, the slow-wave circuit may perform beam-wave interaction with the N electron beams, to amplify power of the radio frequency signa, and because the slow-wave circuit works in a saturation region, electronic efficiency of the travelling-wave tube can be greater than or equal to a first threshold. The output apparatus may output an amplified radio frequency signal.

Abstract: Examples of a ferroelectric memory, a control apparatus, and a method for increasing endurance of the ferroelectric memory are described. One example control apparatus of the ferroelectric memory includes a signal control device. The signal control device is coupled to a memory controller, an alternating current signal generator, and a plate line coupled to a ferroelectric memory cell. The signal control device is configured to switch a signal inputted to the plate line to a first alternating current signal generated by the alternating current signal generator or a read/write pulse signal outputted by the memory controller. In some examples, the signal control device is configured to superimpose a second alternating current signal generated by the alternating current signal generator and the read/write pulse signal, and input a superimposed signal to the plate line.

Abstract: Present application provides a display panel comprising a plurality of pixel units. Each pixel unit consists of two sub-pixels and colors of the two sub-pixels of the each pixel unit are in a complementary color relationship. Each pixel unit produces a white point when the two sub-pixels are together set to a first state and produce a black point when the two sub-pixels are together set to a second state. The plurality of pixel units comprise a plurality of first pixel units and a plurality of second pixel units that are alternately arranged. The two sub-pixels in each of the first pixel units have a first pair of colors in a complementary color relationship, and the two sub-pixels in each of the second pixel units have a second pair of colors in a complementary color relationship.

The first memory page table includes mapping from a virtual address on the host side to a physical address on the host side. A first device side establishes a second memory page table via a shared virtual address agent unit. The second memory page table includes mapping from a virtual address on the first device side to a physical address on the first device side. An agent system memory management unit SMMU on the first device side updates the second memory page table based on the first memory page table, or the host side updates the first memory page table based on the second memory page table.
