US 10,433,179 B2 · Spatial-division multiple access (SDMA) across multiple operators

Abstract

Wireless communications systems and methods related to SDMA operations across multiple network operating entities are provided. A first wireless communication device transmits a communication indicating a reservation for one or more spatial layers in a transmission opportunity (TXOP) of a shared spectrum. The shared spectrum is shared by a first network operating entity and a second network operating entity. The first wireless communication device is associated with the first network operating entity. The first wireless communication device communicates, with a second wireless communication device, data over the one or more spatial layers during the TXOP. The second wireless communication device is associated with the first network operating entity.

Dependent claims

A method of wireless communication, comprising:

communicating, by a first wireless communication device with a second wireless communication device, a communication indicating a reservation for one or more spatial layers in a transmission opportunity (TXOP) of a shared spectrum, wherein the shared spectrum is shared by a first network operating entity and a second network operating entity, wherein the first wireless communication device and the second wireless communication device are associated with the first network operating entity, wherein the first network operating entity includes a number of supportable spatial layers including the one or more spatial layers, and wherein the reservation further indicates whether sharing of remaining unreserved supportable spatial layers is allowed;
and
communicating, by the first wireless communication device with the second wireless communication device, data over the one or more spatial layers during the TXOP.

An apparatus comprising:

a transceiver configured to:
communicate, with a second wireless communication device, a communication indicating a reservation for one or more spatial layers in a transmission opportunity (TXOP) of a shared spectrum, wherein the shared spectrum is shared by a first network operating entity and a second network operating entity, and wherein the apparatus and the second wireless communication device are associated with the first network operating entity, wherein the first network operating entity includes a number of supportable spatial layers including the one or more spatial layers, and wherein the reservation further indicates whether sharing of remaining unreserved supportable spatial layers is allowed;
and
communicate, with the second wireless communication device, data over the one or more spatial layers during the TXOP.

1 more element

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

code for causing a first wireless communication device to communicate, with a second wireless communication device, a communication indicating a reservation for one or more spatial layers in a transmission opportunity (TXOP) of a shared spectrum, wherein the shared spectrum is shared by a first network operating entity and a second network operating entity, wherein the first wireless communication device and the second wireless communication device are associated with the first network operating entity, wherein the first network operating entity includes a number of supportable spatial layers including the one or more spatial layers, and wherein the reservation further indicates whether sharing of remaining unreserved supportable spatial layers is allowed;
and
code for causing the first wireless communication device to communicate, with the second wireless communication device, data over the one or more spatial layers during the TXOP.
