Inter-operator srs resource coordination in sdm-comp

A method of wireless communication, comprising:

• observing, by a non-priority base station associated with a first network operator, resource reservation information identifying priority use of shared resources for sounding reference signals (SRS), wherein the non-priority base station uses shared communication spectrum shared with one or more priority base stations associated with at least one different network operator, wherein the one or more priority base stations have priority access to the shared communication spectrum over the non-priority base station;
• selecting, by the non-priority base station, an available amount of SRS resources for SRS of one or more served user equipments (UEs), wherein the available amount of SRS resources is selected from the shared resources for SRS remaining after the priority use;
• and
• transmitting, by the non-priority base station, a non-priority resource reservation signal to each of the one or more served UEs, wherein the non-priority resource reservation signal identifies the available amount of SRS resources.

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured:
• to determine, at a priority base station associated with a first network operator, an estimated amount of sounding reference signal (SRS) resources for SRS of one or more served user equipments (UEs), wherein the priority base station uses shared communication spectrum shared with one or more non-priority base stations associated with at least one different network operator;
• to transmit, by the priority base station, an SRS request signal to each of the one or more served UEs;
• to convey, by the priority base station, resource reservation information identifying the estimated amount of SRS resources determined;
• and
• to monitor, by the priority base station, for SRS from the one or more served UEs.
