Abstract

The invention relates to the technical field of communication, and discloses a signal sending device and method and electronic equipment. The signal sending device comprises a first switch, a second switch, a multiplexer, a first antenna and a second antenna, wherein a first signal is periodically and alternately sent on the first antenna and the second antenna. A first channel is connected between the first switch and the second switch. When the first signal is transmitted on the second antenna, the first signal is transmitted to the second switch through the first channel, and the second signal is transmitted to the second switch through the multiplexer. Visibly, when the sending antennas of the first signal and the second signal are different, the signal sending device uses two transmission channels to transmit the first signal and the second signal respectively, and therefore the sending antennas of the second signal are prevented from being switched together under the condition that only the first signal is switched to the to-be-switched antenna. Normal operation of the network corresponding to the second signal can be maintained.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal sending device, method and electronic equipment. Background technique [0002] During wireless communication, the signal transmitted by the terminal device to the base station can be used by the base station to determine the uplink channel information from the terminal device to the base station. The signal transmitted by the terminal device to the base station includes, for example, a sounding reference signal (SRS). Terminal equipment can use the same antenna to send signals each time, or it can send signals on several antennas in turn. Rotation means that the antenna that the terminal device sends a signal each time is different from the antenna that sent a signal last time. Communication systems of different network standards correspond to signals of different frequencies. If the terminal device supports communication systems of multiple network...
