Problems solved by technology

Multiple SRS ports of a terminal can occupy the same time domain resource when sending SRS, and perform resource multiplexing through different CSs (belonging to code domain resources) or transmission combs (comb) (belonging to frequency domain resources), but how does the terminal To determine the CS information and Comb information of each SRS port, the existing technology does not provide a specific technical solution, resulting in the terminal being unable to accurately send the SRS to the base station

Embodiment Construction

[0017] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0018] Such as figure 1 As shown, it is a flow chart of the SRS sending method in the embodiment of the present invention, and its specific processing process is as follows:

[0019] Step 11, receiving SRS configuration indication information sent by the base station, the SRS configuration indication information includes CS configuration indication information and Comb configuration indication information;

[0020] In the LTE-A system, there are multiple SRS ports in the terminal to send SRS to the base station at the same time. At this time, multiple SRS ports occupy the same time domain resources, and multiplex code domain resources through different CS information or use different Comb information. Perform frequency ...

Abstract

The invention discloses a sounding reference signal transmitting method, device and terminal. The method comprises the following steps: receiving sounding reference signal (SRS) configuration indication information transmitted by a base station, wherein the SRS configuration indication information contains cycle shift (CS) configuration indication information and transmission comb configuration indication information; determining CS information of each SRS port according to the CS configuration indication information; determining the comb information of each SRS port according to the comb configuration indication information; and transmitting SRSs to the base station through the SRS ports according to the determined CS information and the determined comb information of the SRS ports. The invention provides the terminal with a specific technical for determining the CS information and the comb information of the SRS ports.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and terminal for sending a sounding reference signal. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, a terminal generally detects an uplink channel by sending a Sounding Reference Signal (SRS, Sounding Reference Signal), and the SRS is multiplexed on the last symbol of an uplink subframe in the time domain. The base station can obtain uplink channel state information through SRS, so as to perform operations such as uplink timing detection, power control, uplink frequency domain scheduling, and link adaptation. In the LTE system, the terminal will continue to send SRS at a certain period, and the transmission parameters of SRS are configured by the high layer, including SRS cyclic shift (CS, Cycle Shift) information, bandwidth information, frequency hopping parameter information, cycle information and send...
