example 1

[0062] In the processing of the first node, it may also include:

[0063] determining a DMRS sequence corresponding to the parameter to be used by the first node based on the first correspondence between the DMRS sequence and the parameter;

[0064] or,

[0065] Based on the second correspondence between the DMRS sequence and the parameter combination, determine the DMRS sequence corresponding to the parameter combination to be used by the first node.

[0066] Correspondingly, the processing of the second node may also include:

[0067] Based on the first correspondence between the DMRS sequence and the parameter, determine that the parameter corresponding to the DMRS sequence of the PUSCH is the parameter to be used by the first node;

[0068] Or, based on the second correspondence between the DMRS sequence and the parameter combination, determine that the parameter combination corresponding to the DMRS sequence of the PUSCH is the parameter combination to be used by the fi...

[0091] The processing manner of the first node may also include:

[0092] Based on the third corresponding relationship between the scrambling method and the parameter, determine the scrambling method corresponding to the parameter to be used by the first node;

[0093] or,

[0094]Based on the fourth corresponding relationship between the scrambling method and the parameter combination, determine the scrambling method corresponding to the parameter combination to be used by the first node.

[0095] Correspondingly, the processing of the second node may include: based on the third correspondence between the scrambling method and the parameter, determining that the parameter corresponding to the scrambling method adopted by the PUSCH is the parameter to be used by the first node;

[0096] Or, based on the fourth correspondence between the scrambling scheme and the parameter, determine that the parameter combination corresponding to the scrambling scheme adopted by the PUSCH is...

[0113] The processing manner of the first node may also include:

[0114] If the UCI is used to indicate the parameters to be used, the UCI and the PUSCH are multiplexed and transmitted in a rate matching or disturbing manner;

[0115] Alternatively, if the UCI is used to indicate the parameter combination to be used, the UCI and the PUSCH are multiplexed and transmitted in a manner of rate matching or scrambling.

[0116] Correspondingly, the processing of the second node may further include: receiving the UCI multiplexed with the PUSCH sent by the first node; and determining the parameter or the combination of parameters to be used by the first node based on the UCI.

[0117] The length of the UCI information, the length of the indication information in the MAC CE, and the length of the indication information carried by the uplink channel are determined according to the number of parameters of the same type, or, according to the parameters of the same type The number of com...

Abstract

The invention provides a signal sending and receiving method, a node and a storage medium, and the method comprises the steps that a first node selects a to-be-used parameter from a plurality of parameters of a PUSCH (Physical Uplink Shared Channel) resource, or selects a to-be-used parameter combination from a plurality of parameter combinations of the PUSCH resource, wherein the plurality of parameter types are the same, the parameter type comprises at least one of an index Index of a channel sounding reference signal SRS resource, a path loss reference signal and spatial relationship information, the parameter combination is a combination of the parameter types, and the parameter type combination modes of the plurality of parameter combinations are the same; and sending a PUSCH on the PUSCH resource, and indicating a parameter to be used by the first node or a parameter combination to be used to a second node. Therefore, the problem that which parameter or resource is adopted by theopposite terminal for communication cannot be determined is avoided.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a signal sending and receiving method, node and storage medium. Background technique [0002] In the future wireless communication, it will be extended to support carrier frequencies higher than those used in the fourth generation (4G) communication system, such as 28GHz, 45GHz, etc., and the potential operating frequency band of the system will reach 100GHz. In the high frequency band (greater than 6GHz), due to the large attenuation of electromagnetic waves, beamforming methods are usually required to resist signal attenuation and increase the transmission distance of signals. Therefore, signals are usually sent and received in beams. At this time, when the PUSCH (Physical Uplink Share Channel, physical uplink shared channel) is configured with multiple beam directions, there may be a problem that the network side cannot determine which beam communication t...
