Time interleaved coverage zones in wireless networks
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for creating coverage zones (CZs) at a Citizens Broadband Radio Service Device (CBSD) nodes where each CZ is defined by a respective Physical layer Cell Identity (PCI), and each CZ is allocated a respective time slot having a duration selected in accordance with a type of wireless device (WD) to be supported by the CZ, and each CZ communicates during its respective time slot via some or all of the antennas or antenna sections (e.g., coverage areas or sections S 1 -S 3 ) of the node such that the node communicates with different types of WD in a time-interleaved manner via some or all of the coverage areas associated with the node.
1. Provider equipment, comprising:
a plurality of antennas configured to support radio frequency (RF) communications within respective sectors to provide thereby wireless services to user equipment (UE); and
a controller, configured to create at least two time-interleaved coverage zones by transmitting a respective physical cell identity (PCI) to at least a portion of the plurality of available sectors during each of at least two time slots;
wherein each coverage zone is associated with a respective PCI and configured for use by a respective type of equipment.
2. The provider equipment of claim 1 , wherein the provider equipment comprises a Citizens Broadband Radio Service Device (CBSD), and the controller is further configured register the CB SD with a Spectrum Access System (SAS).
3. The provider equipment of claim 1 , wherein for each time slot the controller is configured to transmit the same PCI to each of the sectors.
4. The provider equipment of claim 1 , wherein for at least one sector the controller is configured to transmit the same PCI during each time slot.
5. The provider equipment of claim 1 , wherein each of a plurality of time slots is associated with a respective type of equipment, and the controller is configured to allocate additional time slots to equipment types requiring additional bandwidth.
6. The provider equipment of claim 1 , wherein the types of equipment comprise user terminals, and fixed wireless access devices.
7. The provider equipment of claim 1 , wherein the types of equipment comprise user terminals, fixed wireless access devices, and Internet-of-Things (IoT) devices.
8. The provider equipment of claim 4 , wherein transmitting one PCI from each of the plurality of available sectors uses substantially an entirety of bandwidth of the available sectors.
9. The provider equipment of claim 1 , wherein at least a portion of the sectors provide RF communications within a Citizens Broadband Radio Service (CBRS) spectral region.
10. The provider equipment of claim 1 , wherein each time slot has associated with it a respective duration selected to allocate, to the time slot, bandwidth sufficient to service equipment using the time slot.
11. The provider equipment of claim 1 , wherein the duration of at least one time slot is periodically adjusted in response to imbalances in bandwidth utilization levels of at least a portion of the time slots.
12. The provider equipment of claim 1 , wherein each time slot is associated with a respective minimum duration selected to allocate to the time slot a minimum bandwidth to service equipment using the time slot.
13. The provider equipment of claim 1 , wherein a protocol associated with communications via at least one time slot is periodically adjusted in response to a determination that a different protocol is appropriate to a currently served type of equipment.
14. The provider equipment (PE) of claim 1 , wherein each of the PE and other PE form a respective nodes within a multiple-node wireless network suitable for delivering networking services to subscribers, the controller being further configured to create coverage zones that do not interfere with coverage zones of adjacent PE.
15. The provider equipment of claim 1 , wherein each coverage zone is configured for use in accordance with a Quality of Service (QoS) class.
16. The provider equipment of claim 1 , wherein each QoS class defines one or more of download throughput, upload throughput, and data transmission latency.
17. Computer readable apparatus comprising a non-transitory storage medium, the non-transitory storage medium comprising at least one computer program having a plurality of instructions, the plurality of instructions configured to, when executed on a processing apparatus, cause a controller apparatus to:
create at least two time-interleaved coverage zones, by transmission of a respective physical cell identity (PCI) to at least a portion of a plurality of available sectors during each of at least two time slots;
wherein each coverage zone is associated with a respective PCI and configured for use by a respective type of equipment.
