Abstract: A communication resource determining method and a communication apparatus are provided, so that a resource for communicating a physical downlink control channel between an access network device and a terminal device is well applicable to cell load when the cell load changes. The method in this application may include: The access network device determines first indication information based on load information of a cell, and sends the first indication information to the terminal device. The terminal device determines, based on the first indication information and first information, a first resource used by the terminal device to detect the physical downlink control channel. The first information includes a plurality of pieces of resource information, the first indication information corresponds to first resource information in the plurality of pieces of resource information, and the first resource information indicates the first resource.

Abstract: The present disclosure relates to random access methods, apparatus, and devices. One example method includes adjusting a sweeping parameter of a receive beam when at least one target receive beam is determined based on prior information, and sweeping the receive beam based on the adjusted sweeping parameter. The prior information includes at least one of cell historical information or cell handover information. The sweeping parameter includes at least one of a sweeping frequency, a sweeping sequence, a beam direction, or a beam width. The receive beam includes the at least one target receive beam. The receive beam is used to receive a random access preamble sent by a terminal. After a base station receives, on the receive beam, the random access preamble sent by the terminal, the terminal randomly accesses the base station for data communication.

Abstract: A method includes disconnecting a data bus connecting a test access port (TAP) controller of an integrated circuit (IC) chip to a plurality of test data registers deployed on the chip, simultaneously supplying test data to multiple test data registers among the plurality of test data registers, and storing test response data, received from the plurality of test data registers and responsive to the test data, in storage registers deployed on the chip.

Abstract: A random access method, base station, and terminal, where a base station detects a first preamble value, and generates at least two random access response messages based on the first preamble value. At least one random access response message includes a second preamble value, and at least one random access response message includes a third preamble value, where the second preamble value is the same as the first preamble value, and the third preamble value is a preamble value obtained after the base station adds a preset accumulation number to the first preamble value. The base station then sends the at least two random access response messages to a terminal.
