Abstract: This application provides a resource configuration method and apparatus. A multiplexing type between a second functional unit and each of one or more antenna panels of a first functional unit is indicated to an IAB node, so that the IAB node obtains a resource configuration of an MT or a resource configuration of a DU based on the multiplexing type. This helps implement a resource configuration in the IAB node in a case of a plurality of antenna panels.

Abstract: A measurement method using a synchronization signal block, a terminal device, and a base station. In the method, a terminal device can determine a first adjustment parameter of a to-be-measured neighboring cell, and determine, based on the first adjustment parameter, a first synchronization signal block-based measurement timing configuration SMTC window corresponding to the to-be-measured neighboring cell. Then, the terminal device measures the to-be-measured neighboring cell based on the first SMTC window.

Abstract: Embodiments of this disclosure provide a paging method and an associated communication apparatus, medium, and chip. According to embodiments of this disclosure, an access network device sends information including an address of the access network device and an identifier of a terminal device to a core network device. The core network device determines an area for paging based on the address of the access network device, and sends a paging message including the identifier of the terminal device to the access network device. The access network device sends a radio access network paging message to the terminal device. In this manner, the area in which paging needs to be performed by the core network device can be reduced, thereby avoiding a waste of unnecessary paging resources.

Abstract: This application discloses a signal transmission method, including: obtaining, by a terminal device, to-be-transmitted data, uplink control information, and a demodulation reference signal; mapping the to-be-transmitted data, the uplink control information, and the demodulation reference signal to generate multiplexed symbols. The multiplexed symbols include DFT-s-OFDM symbols or OFDM symbols. N first multiplexed symbols are located on one side or two sides of a second multiplexed symbol. A location relationship between each of the N first multiplexed symbols and the second multiplexed symbol satisfies a mapping condition. N is an integer greater than or equal to 1. The first multiplexed symbol is a multiplexed symbol to which the uplink control information is mapped, and the second multiplexed symbol is a multiplexed symbol to which the demodulation reference signal is mapped.
