US 11,690,055 B2 · Resource allocation across coexisting radio access technologies

Abstract

The systems, methods, and techniques described in this disclosure allow different wireless systems that operate in accordance with different Radio Access Technologies (RATs) to coexist within a same frequency domain with minimal (if any) inter-RAT interference. Specifically, the described techniques allocate a respective, mutually-exclusive portion of a plurality of Space-Time-Frequency (STF) resources for use in communicating in accordance with each different RAT. For example, mutually-exclusive portions of spatial domain resources, time domain resources, and/or frequency domain resources may be respectively allocated for exclusive use by different RATs. A centralized, third-party controller (120) may perform the allocations, or the allocations may be cooperatively arrived at between systems supporting different RATs, e.g., in a peer-to-peer manner. STF resource allocations may be static and/or dynamic over time, and STF resources may be uniquely identified by respective resource identifiers.

Dependent claims

A method in one or more wireless network infrastructure elements for utilizing radio interface resources, the method comprising:

allocating, by a centralized allocation controller, a first subset of a plurality of spatial domain resources for communicating in accordance with a first Radio Access Technology (RAT) and using a particular frequency spectrum;
allocating, by the centralized allocation controller, a second subset of the plurality of spatial domain resources for communicating in accordance with a second RAT, which is different from the first RAT, and using the particular frequency spectrum, so that spatial radiation patterns corresponding to the first subset of spatial domain resources and to the second subset of spatial resources do not overlap;
and
providing, by the centralized allocation controller(i) a first indication of the allocated first subset of spatial domain resources to a first controller associated with the first RAT, and (ii) a second indication of the allocated second subset of spatial domain resources to a second controller associated with the second RAT.

One or more non-transitory media respectively storing thereon instructions that, when executed by a centralized allocation controller, cause one or more communications systems to:

allocate a first subset of a plurality of spatial domain resources for communicating in accordance with a first Radio Access Technology (RAT) and using a particular frequency spectrum;
allocate a second subset of the plurality of spatial domain resources for communicating in accordance with a second RAT, which is different from the first RAT, and using the particular frequency spectrum, so that spatial radiation patterns corresponding to the first subset of spatial domain resources and to the second subset of spatial resources;
and
provide (i) a first indication of the allocated first subset of spatial domain resources to a first controller associated with the first RAT, and (ii) a second indication of the allocated second subset of spatial domain resources to a second controller associated with the second RAT, thereby causing concurrent delivery of first data via the allocated first subset of spatial domain resources and second data via the allocated second subset of spatial domain resources.
