5G new radio with sharing between priority access license and general authorized access communications

Abstract:

Sharing between priority access license (PAL) and general authorized access (GAA) communications in 5G new radio (NR) systems in 3.5 GHz Spectrum Access System (SAS)/License Shared Access (LSA) operations is disclosed. A resource configuration may be defined that identifies a plurality of sound reference signal (SRS) resources including at least a sounding set of SRS resources and a coexistence set of SRS resources. When communication may occur between PAL entities, a base station transmits a trigger signal to a served UE. The UP transmits an SRS in response to the trigger signal using the coexistence set of SRS resources. The SRS over the coexistence set of resources may reserve communication on the shared communication channel.
