Embodiment 1

[0030] An embodiment of the present invention provides a method for receiving a reference signal, which can be applied to a first communication node, figure 1 It is a flowchart of an embodiment of a method for receiving a reference signal in an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0031] Step 101: Determine reference signal resources used for sending reference signals.

[0032] Here, step 101 may be performed by the first communication node. For example, the first communication node directly acquires the reference signal resource used by the sending device (such as the second communication node) to send the reference signal.

[0033] Optionally, the reference signal resources may be frequency domain resources. When the reference signal resources include frequency domain resources, the frequency domain resources used for sending the reference signal are determined according to the sending comb index of the reference signal. ...

Embodiment 2

[0048] An embodiment of the present invention provides a method for sending a reference signal, which can be applied to a second communication node, figure 2 It is a flowchart of an embodiment of a method for sending a reference signal in an embodiment of the present invention, such as figure 2 As shown, the method includes:

[0049] Step 201: Determine reference signal resources used for sending reference signals.

[0050] Here, step 201 may be performed by the sending device. For example, the second communication node determines the reference signal resource used when sending the reference signal, sends the reference signal according to the determined reference signal resource; and sends the resource information used by the reference signal to the receiving device (such as: the first communication node), The reference signal is received by the receiving device according to the resource information.

[0051] Optionally, the reference signal resources may be frequency dom...

Embodiment 3

[0064] When the reference signal resources include frequency domain resources, the frequency domain resources used for sending the reference signal are determined according to the sending comb index of the reference signal.

[0065] In the first optional method for determining the transmission comb index, the method of determining the transmission comb index of the reference signal includes one of the following: determining the transmission comb index and index offset of the reference signal according to the transmission comb index and index offset configured by the high-level radio resource control RRC signaling Sending comb index: determine the sending comb index configured using the reference signal resource on the first time domain symbol in the reference signal resource, and use the predefined sending comb index of the reference signal on the remaining time domain symbols.

[0066] Further, the index offset of the reference signal can be determined according to at least on...

Abstract

The embodiment of the present invention discloses a method for receiving and sending a reference signal. The receiving method includes: determining a reference signal resource used for sending a reference signal; and receiving a reference signal sent by using the reference signal resource. The sending method includes: determining a reference signal resource used for sending a reference signal; and sending a reference signal using the determined reference signal resource. In this way, a random allocation of resources can be realized by determining the resources used for sending reference signals, and the randomly allocated resources are used to send reference signals, which can effectively avoid interference between cells. The embodiment of the invention also discloses a receiving device, a sending device and a storage medium.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and computer-readable storage medium for receiving and sending a reference signal. Background technique [0002] In related technologies, such as Long Term Evolution (LTE for short) technology, a Physical Downlink Control Channel (PDCCH for short) is used to carry uplink and downlink scheduling information and uplink power control information. Downlink Control Information (DCI for short) format (format) is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release 12 ( In LTE-A version 12), DCI formats 2B, 2C, and 2D are added to support a variety of different applications and transmission modes. The first communication node, such as: a base station (e-Node-B, referred to as eNB), can configure the second communication node, such as: user equipment (User Equipment, referred to as UE) through downlink control information...
