Abstract: This application provides embodiments of an uplink power control method and an apparatus, so that impact of interference between network devices on uplink signal transmission can be reduced, thereby helping increase a probability of successfully receiving an uplink signal by a network device. The method includes: determining, by a network device, an uplink power adjustment parameter value of a terminal device, where the uplink power adjustment parameter value is related to cross-link interference received by the network device; and sending, by the network device, information about the uplink power adjustment parameter value to the terminal device.

Abstract: The present disclosure relates to retuning methods and apparatus. One example method includes determining a first resource and a second resource, where the first resource is used to send a SRS, the first resource is determined based on a first frequency domain resource and at least one symbol of a first subframe, the second resource is used to send a PUSCH or a PUCCH, the second resource is determined based on a second frequency domain resource and a second subframe, all or a part of the first frequency domain resource is not in the second frequency domain resource, the first subframe is the first subframe in two consecutive subframes, and the second subframe is the second subframe in the two consecutive subframes, and determining, in at least one of the first subframe or the second subframe, a guard period for retuning.

Abstract: Embodiments of the present invention disclose a resource allocation method, a first node, and a second node. The method includes the following steps: A first node receives downlink control information (DCI) from a second node, where the DCI includes resource indication information, and the resource indication information is used to indicate a transmission resource allocation manner; the first node determines a first resource allocation manner based on the resource indication information, where the first resource allocation manner is used to allocate a transmission resource greater than one narrowband; the first node determines an allocated transmission resource based on the first resource allocation manner and the resource indication information; and the first node transmits data by using the allocated transmission resource.

Abstract: A first access network device sends indication information to a second access network device within a first time segment of a first subframe. The first subframe includes a second time segment and the first time segment, the second time segment is used by the first access network device to communicate with a first terminal device, the indication information includes first information, and the first information indicates a communication type of the first access network device within a first target time segment of a second subframe. The first access network device further communicats with a second terminal device or the first terminal device based on a communication type indicated by the first information within the first target time segment. The second access network device can detect a signal interference status in time, and the second access network device can use an interference coordination technology in time.
