Patent ID: 11864174
Assignee: SHANGHAI LANGBO COMMUNICATION TECHNOLOGY COMPANY LIMITED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. The first node according to claim 1, wherein:
when the operating action involves receiving:
a given parameter group is any parameter group in the first parameter-group set;
the given parameter group is used for a reception of the first signal group;
a given reference signal resource in the first reference-signal-resource set is used for determining the given parameter group;
the given reference signal resource is reserved for a given reference signal;
the given parameter group comprises large-scale properties;
the large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average delay, and Spatial Rx parameters; and
all or part of large-scale properties of a channel that the given reference signal goes through are used for inferring all or part of large-scale properties of a channel that the first signal group goes through; and

when the operating action involves transmitting:
a given parameter group is any parameter group in the first parameter-group set;
the given parameter group is used for a transmission of the first signal group;
a given reference signal resource in the first reference-signal-resource set is used for determining the given parameter group;
the given reference signal resource is reserved for a given reference signal;
the given parameter group comprises a spatial-domain filter; and
the first node employs a same spatial-domain filter for transmitting the first signal group and receiving the given reference signal.
