摘要： This application provides a resource selection method and apparatus, and relates to the communication field, so that interference on a resource that is determined by a terminal and that is used for data transmission is small or does not exist, thereby improving transmission reliability. The method includes: A first terminal determines a candidate resource set, where the candidate resource set does not include a first resource. Interference power on a second resource associated with the first resource is greater than or equal to a first threshold. A periodic extension resource of the second resource overlaps a resource set corresponding to the first resource, and the periodic extension resource of the second resource is determined based on the second resource and a first period of a second terminal. A time domain location of the second resource overlaps a time domain location of a third resource, and a frequency domain location of the second resource does not overlap a frequency domain location of the third resource. Interference power on the second resource is determined based on power that a signal carried on the third resource leaks on the second resource, the third resource is a resource in a sensing window, and the signal carried on the third resource is a PSCCH and/or a PSSCH of the second terminal.

摘要： This application provides an information processing method and an electronic device, and relates to the communication field. In this application, a first device can determine location information of a second device based on first frequency difference information and second frequency difference information. The first frequency difference information indicates a difference between frequencies at which the second device receives reference signals of two devices. In other words, the first frequency difference information is the difference between the frequencies at which the second device receives the reference signals of the two devices. The first frequency difference information can be used to reduce impact of a local frequency error of the second device. In addition, the difference between the frequencies at which the second device receives the reference signals of the two devices is also related to a difference between frequencies at which the two devices send the reference signals. Therefore, a second frequency difference can be used to reduce impact of errors in the frequencies at which the two devices send the reference signals, and improve accuracy of determining the location information of the second device.

摘要： A configuration parameter update method and an apparatus are provided. The method includes: when detecting that a first signal power of a first reference signal is less than a preset power, measuring, by a terminal in an RRC inactive state, candidate reference signals corresponding to candidate configuration parameters; determining, from the candidate reference signals, a first candidate reference signal that meets a preset condition, and sending a signal parameter of the first candidate reference signal to a first serving base station; and adjusting a beam direction and/or a transmit power of an uplink SRS based on the first candidate reference signal. According to the method, the terminal in the RRC inactive state adjusts the beam direction of the uplink SRS in a timely manner without switching a status. In addition, a base station participating in positioning may adjust a receive beam of the uplink SRS in a timely manner based on a signal parameter, thereby implementing positioning of the terminal in the RRC inactive state.

摘要： This application provides a downlink scheduling method and an apparatus. The method includes: A terminal device reports first capability information to a network device, where the first capability information indicates that values of a maximum quantity of downlink MIMO layers supported by the terminal device on a first component carrier CC include a first maximum quantity M1 of downlink MIMO layers and a second maximum quantity M2 of downlink MIMO layers; and the terminal device receives first signaling sent by the network device, where the first signaling configures maximum MIMO layer quantity information corresponding to the first CC, and the maximum MIMO layer quantity information includes a first maximum quantity N1 of MIMO layers and a second maximum quantity N2 of MIMO layers. The first maximum quantity N1 of MIMO layers is not greater than the first maximum quantity M1 of downlink MIMO layers, and the second maximum quantity N2 of MIMO layers is not greater than the second maximum quantity M2 of downlink MIMO layers. According to the method, the network device can directly switch or dynamically adjust, after activating or deactivating one or more carriers by using a MAC CE, a maximum quantity of MIMO layers on an activated CC without reconfiguring a PDSCH parameter by using RRC signaling. This can avoid a delay and overheads caused by RRC-based reconfiguration.
