Abstract

The embodiment of the invention provides a pilot signal transmission method and communication equipment, which can avoid the problem of inflexibility caused by pre-configuration of transmission resources and can avoid waste of the resources. The method comprises that a first device receives a first message sent by a second device, wherein the first message is used for instructing the first device to receive or send a pilot signal, and the first message comprises resource configuration information of the pilot signal; according to the resource configuration information, the first device sends the pilot signal to the second device or receives the pilot signal sent by the second device, wherein the first device is a terminal device, and the second device is a network device.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2016 / 098712 with the filing date of September 12, 2016, which entered the Chinese national phase with the Chinese patent application number 201680089009.1, and the title of the invention is "Transmission method and equipment for pilot signals" . technical field [0002] The present application relates to the communication field, and more specifically, to a pilot signal transmission method and device. Background technique [0003] Aperiodic SRS transmission is introduced in the Long Term Evolution (LTE) system, and the base station can trigger the transmission of the Sounding Reference Signal (SRS) of the terminal equipment through downlink control information (Downlink Control Information, DCI). After receiving the SRS trigger signaling, the terminal device performs SRS transmission on the closest resource among the pre-configured resources for transmitting aperiodic SRS. T...
