Abstract

The present disclosure provides a method and apparatus for transmitting and receiving an uplink signal, a storage medium, and an electronic device. The transmitting method includes: a second communication node receives configuration information transmitted by a first communication node through physical downlink control signaling or high-layer signaling, and the second communication node transmits an uplink signal to the first communication node based on the configuration information; or a second communication node transmits, according to a rule appointed with a first communication node, an uplink signal to the first communication node.

Claims18

Dependent claims

A method for transmitting an uplink signal, comprising:

receiving, by a second communication node, configuration information transmitted by a first communication node through physical downlink control signaling or high-layer signaling, and transmitting, by the second communication node, an uplink signal to the first communication node based on the configuration information, wherein the configuration information comprises one or more slot offsets;
or,
transmitting, by a second communication node according to a rule appointed with a first communication node, an uplink signal to the first communication node;
wherein transmitting, by the second communication node, an uplink signal to the first communication node based on the configuration information comprises:
in a case where the number of the one or more slot offsets in the configuration information is 1 and reference signal resources in a reference signal resource set configured by the first communication node for the second communication node are distributed in slot 1 and slot 2, transmitting, by the second communication node, the uplink signal to the first communication node in slot 1 and slot 2;
and in a case where the number of the one or more slot offsets in the configuration information is 2, reference signal resources in a reference signal resource set configured by the first communication node for the second communication node are distributed in slot 1 and slot 2, the number of reference signal resources in slot 1 is 2 and the number of reference signal resources in slot 2 is 2, transmitting, by the second communication node, the uplink signal to the first communication node in slot 1 and slot 2.
