Abstract

The embodiment of the invention discloses a method and a device for determining a tracking reference signal period, which can be applied to the technical field of communication, and the method executed by network equipment comprises the following steps: sending first indication information to terminal equipment in a physical layer, the first indication information being used for indicating a change period of a tracking reference signal TRS. Therefore, the process of updating the TRS period does not influence the network signaling, and the influence of updating the TRS period on the power consumption of the network equipment is reduced.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for determining a period of a tracking reference signal. Background technique [0002] In a communication system, when a terminal device receives downlink data transmission, it needs to continuously track and compensate time offset and frequency offset according to the measured Tracking Reference Signal (TRS), so as to ensure the accuracy of downlink data reception. In the related art, the period of the TRS generally includes 5 milliseconds (ms), 10 ms, 20 ms, 40 ms and 80 ms. For short-period TRS, if the TRS period is changed by changing the configuration period of the channel state information (CSI) reference signal (Reference signal, RS) of the network equipment, it will not only affect the load of network signaling, but also Increase the power consumption of network equipment.
