Embodiment Construction

[0126] In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

[0127] (1) In the embodiments of this application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand their meanings.

[0128] (2) The term "multiple" in the embodiments of the present application refers to two or more, and other quantifiers are similar.

[0129] (3) "And / or", which describes the association relationship of associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists independently. Condition. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0130] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction w...

Abstract

The present application discloses a reference signal transmission method and device. In this application, the base station sends a first reference signal trigger or activation signaling to the terminal, where the first reference signal trigger or activation signaling is used to instruct the terminal to send the first reference signal according to the resource configuration information of the first reference signal; The base station receives the first reference signal sent by the terminal according to the first reference signal trigger or activation signaling; wherein, the initial sending time unit of the first reference signal is the first uplink that satisfies n+k A time unit, n is used to identify a sending time unit of the first reference signal trigger or activation signaling, k is an integer greater than or equal to K, and K is an integer greater than or equal to 0.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a reference signal transmission method and device. Background technique [0002] In existing communication systems, some reference signals are transmitted after being configured. For example, a periodic reference signal (such as a periodic sounding reference signal (sounding reference signal, SRS), a periodic channel state information reference signal (channel state information-reference signals, CSI-RS)), as long as the reference signal resource is configured, Then the transmission of the reference signal is performed periodically. Some reference signals are not transmitted immediately after being configured, but can only be transmitted after being triggered. For example, an aperiodic reference signal in a long term evolution (long term evolution, LTE) system starts to be transmitted only after the base station sends an activate (activate) signaling to t...
