Embodiment 1

[0027] The embodiment of the present invention provides a method for reporting SRS power headroom, which is applied to terminal equipment, such as figure 1 As shown, the method includes:

[0028] Step 101: Calculate the expected SRS transmission power on at least one SRS resource included in the target SRS resource set; wherein, the target SRS resource set is the SRS resource set on the target carrier or the target bandwidth part BWP;

[0029] Step 102: Calculate and obtain the power headroom PH of the target SRS resource set according to the expected SRS transmission power on the at least one SRS resource;

[0030] Step 103: Report the calculated PH of the target SRS resource set.

[0031] Specifically, in the above step 101, the calculation of the expected SRS transmission power on at least one SRS resource included in the target SRS resource set includes:

[0032] If the terminal device sends an SRS on the SRS resource at the time of calculating the PH, calculate the expe...

Embodiment 2

[0097] An embodiment of the present invention provides a terminal device, such as figure 2 As shown, the method includes:

[0098] The processing unit 21 is configured to calculate the expected SRS transmission power on at least one SRS resource contained in the target SRS resource set; wherein, the target SRS resource set is the SRS resource set on the target carrier or the target bandwidth part BWP; according to the at least one SRS The expected SRS transmission power on the resource is calculated to obtain the power headroom PH of the target SRS resource set;

[0099] The communication unit 22 reports the calculated PH of the target SRS resource set.

[0100] Specifically, the processing unit 21, if the terminal device sends an SRS on the SRS resource at the moment of calculating the PH, then based on the transmission parameters of the sent SRS and the power configured for the SRS resource or the target SRS resource set The control parameter calculates the expected SRS t...

Abstract

The invention discloses an SRS power headroom reporting method, terminal equipment and a computer storage medium. The method comprises the following steps: calculating expected SRS sending power on atleast one SRS resource contained in a target SRS resource set; wherein the target SRS resource set is an SRS resource set on a target carrier or a target bandwidth part BWP; according to the expectedSRS sending power on the at least one SRS resource, calculating to obtain the power headroom PH of the target SRS resource set; and reporting the calculated PH of the target SRS resource set.

Description

[0001] This application is a PCT international patent application PCT / CN2018 / 078347 with an application date of March 7, 2018, which entered the Chinese national phase. The Chinese patent application number 201880064819.0, the invention name is "SRS power headroom reporting method, terminal equipment and computer storage Medium" divisional application. technical field [0002] The present invention relates to the technical field of information processing, in particular to a method for reporting SRS power headroom, a terminal device and a computer storage medium. Background technique [0003] The SRS power headroom is the difference between the maximum transmission power allowed by the UE and the currently calculated SRS transmission power. In NR, the terminal needs to perform power headroom report (Power Headroom Report, PHR) for PUSCH and SRS respectively. The terminal not only needs to report PH (Power Headroom) for the carrier that currently transmits PUSCH or SRS, but a...
