Abstract

Wireless communication systems and methods related to spectrum use negotiations are provided. A first wireless communication device transmits, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum for a time period. The first wireless communication device receives, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from a first priority to a second priority for accessing the spectrum during the time period. The first wireless communication device communicates with a second wireless communication device in the spectrum during the time period based on the second priority, where at least the first wireless communication device or the second wireless communication device is associated with the local operator.

transmitting, by the controlling entity, a spectrum use grant indicating that the local operator is promoted from being a non-primary user of the spectrum to the primary user with the primary access to the spectrum and another operator is demoted from being the primary user of the spectrum to a non-primary user of the spectrum during a plurality of transmission opportunities (TXOPs) within the time period.

13. The method of claim 12 , further comprising:

granting the local operator a priority over the another operator for accessing the spectrum in the plurality of TXOPs.

14. The method of claim 13 , wherein the another operator is the controlling entity.

15. The method of claim 13 , further comprising transmitting, by the controlling entity to one or more first wireless communication devices, a request to transmit a measurement signal, wherein at least one of the one or more first wireless communication devices is associated with the local operator.

16. The method of claim 15 , wherein the measurement signal includes at least one of a reservation signal, a channel state information-reference signals (CSI-RS), or a sounding reference signal (SRS).

17. The method of claim 15 , further comprising:

transmitting, by the controlling entity to a second wireless communication device associated with the another operator, a request to receive the measurement signal;

receiving, by the controlling entity from the second wireless communication device, a signal measurement report including at least a signal strength of the measurement signal; and

determining, by the controlling entity, to promote the local operator from being the non-primary user of the spectrum to the primary user with the primary access to the spectrum based on at least the signal measurement report.

18. The method of claim 17 , further comprising determining, by the controlling entity, a geographic coverage area based on the signal strength of the measurement signal, wherein the another operator is within the geographic coverage area.

19. The method of claim 17 , further comprising determining, by the controlling entity, to promote the local operator from being the non-primary user of the spectrum to the primary user with the primary access to the spectrum based on at least an expected traffic load of the another operator during the time period.

20. The method of claim 17 , further comprising determining, by the controlling entity, a transmission power adjustment based on at least the signal measurement report, wherein the spectrum use grant further indicates the transmission power adjustment.

21. An apparatus comprising:

a transceiver configured to:

transmit, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum as a primary user with a primary access to the spectrum for a time period; and

receive, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from being a non-primary user of the spectrum to the primary user with the primary access to the spectrum and another operator is demoted from being the primary user of the spectrum to a non-primary user of the spectrum during a plurality of transmission opportunities (TXOPs) within the time period.
