Spectrum access arbiter entity for sharing spectrum resources

A method of wireless communication performed by a network node, comprising:

• transmitting, by a spectrum access arbiter entity associated with the network node and to an open radio access network distributed unit (O-DU) associated with the network node, a grant that permits use of a shared spectrum resource, the grant being associated with a reservation of the shared spectrum resource, and the grant indicating a first cryptographic checksum for a given timeslot in which the shared spectrum resource is granted;
• receiving, by an open radio access network radio unit (O-RU) associated with the network node and from the O-DU, a transmission that includes a second cryptographic checksum, the transmission being received based at least in part on the grant;
• and
• transmitting, by the O-RU, the transmission via the shared spectrum resource based at least in part on an authentication of the transmission, the authentication involving the grant being accepted by the O-RU based at least in part on a verification that the second cryptographic checksum corresponds to the first cryptographic checksum.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network node, cause the network node to:
• transmit, by a spectrum access arbiter entity associated with the network node and to an open radio access network distributed unit (O-DU) associated with the network node, a grant that permits use of a shared spectrum resource, the grant being associated with a reservation of the shared spectrum resource, and the grant indicating a first cryptographic checksum for a given timeslot in which the shared spectrum resource is granted;
• receive, by an open radio access network radio unit (O-RU) associated with the network node and from the O-DU, a transmission that includes a second cryptographic checksum, the transmission being received based at least in part on the grant;
• and
• transmit, by the O-RU, the transmission via the shared spectrum resource based at least in part on an authentication of the transmission, the authentication involving the grant being accepted by the O-RU based at least in part on a verification that the second cryptographic checksum corresponds to the first cryptographic checksum.

An apparatus for wireless communication, comprising:

• means for transmitting, by a spectrum access arbiter entity associated with the apparatus and to an open radio access network distributed unit (O-DU) associated with the apparatus, a grant that permits use of a shared spectrum resource, the grant being associated with a reservation of the shared spectrum resource, and the grant indicating a first cryptographic checksum for a given timeslot in which the shared spectrum resource is granted;
• means for receiving, by an open radio access network radio unit (O-RU) associated with the apparatus and from the O-DU, a transmission that includes a second cryptographic checksum, the transmission being received based at least in part on the grant;
• and
• means for transmitting, by the O-RU, the transmission via the shared spectrum resource based at least in part on an authentication of the transmission, the authentication involving the grant being accepted by the O-RU based at least in part on a verification that the second cryptographic checksum corresponds to the first cryptographic checksum.
