LINK ADAPTATION METHOD AND DEVICE

摘要

The present invention relates to the field of communications, and provides a link adaptation method and device, so as to determine, according to transmission quality of a signal in a link, to perform antenna alignment and/or frequency adjustment. The method includes: detecting, by a first antenna device, an RSSI of a link between the first antenna device and a second antenna device; when it is determined that the RSSI is greater than or equal to a first RSSI threshold, detecting, by the first antenna device, an SINR of the link; and choosing, by the first antenna device according to the RSSI and the SINR, to perform frequency adjustment and/or antenna alignment with the second antenna device. Embodiments of the present invention are applied to link adaptation.

主权项

1. A link adaptation method, comprising:
receiving, by a first wireless device, a signal transmitted over a link between the first wireless device and a second wireless device; detecting, by the first wireless device, a received signal strength indicator (RSSI); detecting, by the first wireless device, a signal to interference plus noise ratio (SINR) in a case that a detected RSSI is greater than or equal to a RSSI threshold; sending, by the first wireless device, an indication to the second wireless device in a case that a detected SINR is greater than or equal to a SINR threshold, wherein the indication indicates that a configuration for the transmission of the signal is adapted to the link between the first wireless device and the second wireless device.
