no. 1 example

[0042] This embodiment provides a signal sending method, please refer to figure 1 , the method includes:

[0043] S101. The second communication node determines resources for sending uplink signals by itself based on signaling configuration or in a predefined manner; wherein the resources include at least one of the following: time domain resources and air domain resources;

[0044] S102. Send an uplink signal based on the determined resource.

[0045] In some embodiments, when the resources include time-domain resources, the time-domain resources include: for the second communication node configured with at least one measurement reference signal SRS resource configuration, when the high-layer parameter resourceType in the SRS resource is set to non- Periodically, for SRS under the first configuration condition, the time-domain resource for sending SRS is the time-domain resource that satisfies the following SRS sending conditions. The minimum time interval between the first...

no. 2 example

[0080] This embodiment provides a method for configuring a sending opportunity in an SRS uplink sending condition in a second communication node.

[0081] When the second communication node is configured with one or more SRS resource configurations, and the high-level parameter resource type (resourceType) in the SRS resource is set to aperiodic, it is configured as beam management for the use in frequency range 2 , codebook, non-codebook, antenna switching at least one of the SRS, the minimum time interval between the last symbol of the PDCCH that triggers aperiodic SRS transmission and the first symbol of the SRS resource is N2+A; where, A is an integer greater than or equal to 0, and the value of A increases as the number of SRS resources included in the SRS resource set increases.

no. 3 example

[0083] This embodiment provides a method for configuring a sending opportunity in an SRS uplink sending condition in a second communication node.

[0084] When the second communication node is configured with one or more SRS resource configurations, and the high-level parameter resource type (resourceType) in the SRS resource is set to aperiodic, the use in frequency range 2 is configured as beam management, codebook, non-periodic For SRS of at least one of codebook and antenna switching, the minimum time interval between the last symbol of the PDCCH that triggers aperiodic SRS transmission and the first symbol of the SRS resource is N2+A; where A is greater than or equal to An integer of 0, the value of A is related to whether the parameter SpatialRelationInfo in the resource is configured or the number of configured SpatialRelationInfo, for example:

[0085] If the UE is not configured with SpatialRelationInfo, then A=42 or A42. If the number of configured SpatialRelationIn...

Abstract

The embodiment of the invention provides a signal sending method and a device, a resource determining method and a device, a terminal, a base station and a storage medium, and the method comprises thesteps: determining the resource of an uplink signal sent by a second communication node through the second communication node based on signaling configuration or according to a predefined mode; and then sending the uplink signal based on the determined resource, so that the condition configuration of SRS uplink sending is realized.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of network communication, and specifically, relate to but are not limited to methods, devices, devices, terminals, base stations and storage media for signal transmission and resource determination. Background technique [0002] In Long Term Evolution (LTE for short), a Physical Downlink Control Channel (PDCCH for short) is used to carry downlink control information (Downlink Control Information, DCI for short), where the DCI may include uplink and downlink Scheduling information, and uplink power control information. The DCI format (format) is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-ARlease 12 (LTE-A version 12) and added DCI format 2B, 2C, 2D to support many different applications and transmission modes. [0003] With the development of communication technology, the demand for data services continues to increase, and th...
