Problems solved by technology

[0004] In order to meet the large-capacity and high-speed transmission requirements of the mobile communication system, a high-frequency frequency band greater than 6 GHz is introduced for communication to take advantage of its large bandwidth and high-speed transmission characteristics. Due to the high path loss of high-frequency communication, narrow beams are required To ensure the propagation distance and high beam gain, the uplink measurement signal or downlink measurement signal is also transmitted with a directional narrow beam. Due to the large number of beams in high-frequency communication, relatively large measurement overhead will be generated

Embodiment 3

[0114] Embodiment 3 provides a method in which a terminal device and a base station send wireless measurement signals in a mixed way of downlink and uplink in a high-frequency system. Refer to image 3 , the method includes:

[0115] 301. The base station sends downlink measurement signals to the terminal device on multiple sending beams;

[0116] The base station can send downlink measurement signals to downlink beams in different directions in the form of beam scanning, so that terminals at different locations can receive them; a terminal device can receive reference signals in one or more beam directions, usually multiple Beam reference signal. For the type of the downlink measurement signal, reference may be made to the downlink measurement signal mentioned in the foregoing embodiments, and details are not described again.

[0117] 302. The terminal device detects signal strengths of downlink measurement signals on the multiple transmission beams, and feeds back a detect...

Abstract

The invention provides a measurement signal transmitting method and device. The measurement signal transmitting method comprises steps: a network apparatus transmits, by means of one or more transmitting beams, a downlink measurement signal to a terminal apparatus; the network apparatus receives a detection result, fed back by the terminal apparatus, of the signal intensity of the downlink measurement signal of one or more transmitting beams; and the network apparatus informs, when detecting that the detection result, fed back by the terminal apparatus, of the downlink measurement signal is less than a set threshold value, the terminal apparatus of using a measurement mode for an uplink measurement signal. The method reduces the signaling overheads due to conversion of a measurement mode according to a measurement result.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly, to a method and device for transmitting measurement signals. Background technique [0002] The radio resource management of the existing wireless communication system usually adopts the measurement method based on the downlink measurement signal, that is, the base station sends the downlink measurement signal, such as the reference signal RS (Reference Signal), and the terminal device measures the RSRP (Reference Signal Received Signal) of the reference signal sent by the base station. Power, Reference Signal Received Power) / RSRQ (ReferenceSignal Received Quality, Reference Signal Received Quality) and other parameters, and report the measurement results to the base station, and the base station determines the handover and movement of the terminal equipment based on the measurement results. [0003] In order to reduce the dependence of radio resource management...
