摘要： Disclosed are a power adjustment method and an apparatus, wherein the power adjustment method comprises: if a second access point of a second basic service set detects a first beacon frame in a monitoring period, the second access point, based on a Received Signal Strength Indicator (RSSI) and a data field in the first beacon frame, determining whether a first node device is in an overlap region between a first basic service set and the second basic service set; and in a condition that the first node device is in the overlap region, the second access point, based on the RSSI, determining an upper limit of data transmission power between a second node device and the second access point. The data transmission power between the second node device and the second access point is determined based on the RSSI, and data transmission power of the second node device is adjusted correspondingly; thus the second basic service set does not interfere with access of the first node device in the overlap region to a first access point and data transmission, and a concurrent transmission probability of the first basic service set and the second basic service set is increased.
