Abstract: A method for controlling a specific absorption rate (SAR) of a wireless communications device and a wireless communications device, and the wireless communications device includes a first antenna and a second antenna. The method includes transmitting, by the wireless communications device, a radio frequency signal using the first antenna, and stopping using the first antenna and starting transmitting the radio frequency signal using the second antenna when transmit power of the first antenna is greater than first preset power and a first time period elapses to enable the wireless communications device to meet an SAR standard. There is no backoff of antenna transmit power in a process of controlling the SAR of the wireless communications device. Therefore, communication quality of the wireless communications device is ensured while the SAR standard is met.

Abstract: A method includes after a user touches a near-field communication (NFC) tag on a second electronic device using a first electronic device having an NFC function, a plurality of functions can be implemented simultaneously. For example, after the user holds a mobile phone to touch an NFC tag on a television, the mobile phone establishes a wireless connection to the television, and synchronizes a video being played on the mobile phone with the television for playing.

Abstract: A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.
