Embodiment 1

[0107] Embodiment 1: The network side device configures the same time slot for the terminal to carry the two resource subsets.

[0108] Assuming that one resource set contains 4 SRS resources, divide the resource set into two resource subsets, each resource subset contains 2 SRS resources, and the network side device configures the resource subsets for the terminal The offset information of set 1 is offset value X=1 time slot, and the offset information of resource subset 2 is Y=1 time slot. At this time, the offset information of resource subset 1 and resource subset 2 is the same, Therefore, the resource subset 1 and the resource subset 2 are in the same time slot, so the positions of the symbols in the time slots of the resource subset 1 and the resource subset 2 need to be different. And in the first time slot, the network side device triggers the terminal to send the SRS resource, and the offset value is one time slot, so the SRS resource is sent in the second time slot. ...

Embodiment 2

[0111]Embodiment 2: The network side device configures for the terminal that the time slots carrying the two resource subsets are different, and the positions of the symbols in the time slots carrying the two resource subsets are the same.

[0112] Assuming that one resource set contains 4 SRS resources, divide the resource set into two resource subsets, each resource subset contains 2 SRS resources, and the network side device configures the resource subsets for the terminal The offset information of set 1 is offset value X=1 time slot, and the offset information of resource subset 2 is Y=2 time slots. At this time, the offset information of resource subset 1 and resource subset 2 are different , so the positions of the symbols in the slots of resource subset 1 and resource subset 2 are the same. And in the first time slot, the network side device triggers the terminal to send the SRS resource, and the offset value is one time slot, so the SRS resource in the resource subset ...

Abstract

The invention discloses a method and equipment for configuring and sending uplink detection pilot frequency, which are used for solving the problems of large transmission information amount, large resource occupation amount and incapability of sending all uplink detection pilot frequencies in a set in an aperiodic condition in the prior art. According to the embodiment of the invention, a networkside determines at least one resource set; for any resource set comprising at least two SRS resources, the network side divides the SRS resources included in the resource set into at least two resource subsets; and the network side configures the resource identifier of the resource included in each resource subset and offset information which corresponds to the resource subset and is used for determining a sending offset value for the terminal. According to the invention, the determined resource set is divided into the plurality of resource subsets, and the offset information is configured foreach resource subset, so that all resources in the set are ensured to be sent during aperiodic configuration sending, the information amount of network configuration is reduced during periodic and semi-continuous configuration sending, the resource occupation amount is small during terminal sending, and the resources are saved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for configuring and sending uplink detection pilots. Background technique [0002] In the 5G NR (New Radio, new air interface) system, the network configures one or more sets of SRS (Sounding Reference Signals, uplink sounding pilots) sets for the terminal, and each set is configured with one or more uplink sounding pilots. In the prior art, when sending the uplink sounding pilot, the terminal may send the uplink sounding pilot periodically, aperiodically and semi-persistently. Which method the terminal uses to send the uplink sounding pilot mainly depends on the configuration of the terminal by the network. [0003] 1. The network configures a periodic uplink sounding pilot set for the terminal, and the terminal sends one or more uplink sounding pilots within a certain period according to the configured information. When the networ...
