Embodiment Construction

[0200] The inventor noticed during the invention that:

[0201] Due to the timeliness requirements of channel heterogeneity, in order to obtain the downlink channel state information as accurately as possible in the measurement results, in theory, the shorter the SRS cycle configuration, the better, but at the same time, the user capacity of the cell supported by this configuration is also reduced accordingly . Therefore, generally, for stationary terminals or terminals with low moving speed, the channel time becomes smaller, and a large-period SRS can be configured to enable the cell to support more users; for a terminal with a high moving speed, a small-period SRS can be configured to better ensure measurement accuracy.

[0202] figure 1 It is a schematic diagram of the cell-level throughput relationship in the scenario where 10 users move at 30km / h. As shown in the figure, the multi-user cell-level throughput is actually measured at this stage, and the 10 users in the cel...

Abstract

The invention discloses a channel detection reference signal configuration method, equipment, a device and a medium. The method comprises the following steps: determining the moving speed of a terminal and / or the number of cell users; configuring the channel detection reference signal period and / or the port number of the terminal according to the moving speed of the terminal and / or the user number of the cell; and allocating channel detection reference signal resources according to the channel detection reference signal period and / or the port number of the terminal. By adopting the method, the channel estimation accuracy of the mobile user can be improved, and the cell-level throughput can be improved. The channel estimation accuracy and the channel detection reference signal resource occupation fairness of users in a cell can be ensured, and the single-user rate is improved. And the cell user capacity can be improved in limited system resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a channel sounding reference signal configuration method, equipment, device and medium. Background technique [0002] The public network refers to an ordinary commercial network, such as an urban or rural commercial network. In the 5G public network, the base station obtains downlink channel state information through SRS (Sounding Reference signals) signals. [0003] The deficiency of prior art is to have at least one of following problems: [0004] There may be inaccurate channel estimation for mobile users; [0005] Issues such as limited user capacity; [0006] There may be a problem that a single user occupies too many SRS resources. Contents of the invention [0007] The present invention provides a channel sounding reference signal configuration method, equipment, device and medium, wherein: [0008] An SRS configuration method, equipment, devi...
