Abstract: A vapor chamber includes a first base plate (12), a second base plate (13), and a capillary structure (15). The first base plate (12) and the second base plate (13) are disposed in a stacked manner and fastened to each other, and together form a cavity (11). The capillary structure is disposed on an inner wall of the cavity (11) and a surface of at least one support pillar (120) between the first base plate (12) and the second base plate (13), and the capillary structure (15) is configured to provide capillary force for returning liquid to a working medium. A reinforcement table (127) located in the cavity (11) is disposed between the first base plate (12) and the second base plate (13).

Abstract: Example synchronization signal sending and receiving methods and apparatus are described. In one example method, a terminal device determines a target frequency resource. A frequency domain position of the target frequency resource is determined based on a frequency domain position offset and a frequency interval of synchronization channels. The terminal device receives a synchronization signal by using the target frequency resource.

Abstract: In a communication method, a terminal device obtains a code division multiplexing capability of a physical resource of an uplink control channel, where the code division multiplexing capability is a length of orthogonal cover codes for multiplexing terminal devices in a code division manner on a unit resource in the physical resource of the uplink control channel, and the code division multiplexing capability configured by higher layer signaling. The terminal device further determines the physical resource based on the code division multiplexing capability, and sends uplink control information on the physical resource.

Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined. The sequence is a sequence {fn} consisting of 12 elements, fn represents an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {fn} are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and a relatively small cubic metric (CM) value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.

Abstract: An uplink channel sending method includes sending, by a terminal device, a first uplink channel to a network device at a first power in a first time unit of a first Bandwidth Part (BWP) region, and sending, by the terminal device, the first uplink channel to the network device at a second power in a second time unit of a second BWP region. The second time unit is adjacent to the first time unit, the second BWP region is different from the first BWP region, and the second power is determined using a reset accumulated closed-loop power, an absolute closed-loop power, or the first power and an offset value.
