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 S1-S3) 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. A method of defining coverage zones at provider equipment (PE) configured for wireless communication via a shared use spectral region managed by a Spectrum Access System (SAS), the method comprising:
registering the PE with a Spectrum Access System (SAS);
transmitting, at the PE, a common physical cell identity (PCI) from each of a plurality of available sectors;
creating, at the PE, a first coverage zone by transmitting a selected first PCI to each of the plurality of available sectors during a first time slot;
creating, at the PE, a second coverage zone by transmitting a selected second PCI to each of the plurality of available sectors during a second time slot;
wherein each coverage zone is configured for use by a respective type of equipment.
2. The method of claim 1 , wherein the types of equipment comprise user terminals, and fixed wireless access devices.
3. The method of claim 1 , further comprising: at the PE, creating a third coverage zone by transmitting a selected third PCI to each of the plurality of available sectors during a third time slot.
4. The method of claim 3 , wherein the types of equipment comprise user terminals, fixed wireless access devices, and Internet-of-Things (IoT) devices.
5. The method of claim 1 , wherein transmitting one PCI from each of the plurality of available sectors uses substantially an entirety of bandwidth of the available sectors.
6. The method of claim 5 , wherein said plurality of available sectors comprises all sectors.
7. The method of claim 1 , wherein said shared use spectral region comprises a Citizens Broadband Radio Service (CBRS) spectral region.
8. The method of claim 1 , wherein the PE comprises a Citizens Broadband Radio Service Device (CBSD) comprising a plurality of antennas supporting respective sectors.
9. The method of claim 4 , 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.
10. The method of claim 9 , 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.
11. The method 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.
12. The method of claim 9 , 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 group of WDs.
13. The method of claim 1 , wherein each of a plurality of PE operates in a coordinated manner to form a multiple-node wireless network suitable for delivering networking services to subscribers.
14. The method of claim 13 , wherein coverage zones of deployed PE are configured to avoid interfering with coverage zones of adjacent deployed PE.
15. The method of claim 1 , wherein each coverage zone is configured for use in accordance with a Quality of Service (QoS) class.
16. The method of claim 15 , wherein each QoS class defines one or more of download throughput, upload throughput, and data transmission latency.
17. An apparatus, comprising:
a Citizens Broadband Radio Service Device (CBSD), comprising antennas supporting radio frequency (RF) communications via respective sectors and a controller configured to register the CBSD with a Spectrum Access System (SAS), the controller further configured for:
creating a first coverage zone by transmitting a selected first physical cell identity (PCI) to each of the plurality of available sectors during a first time slot;
creating a second coverage zone by transmitting a selected second PCI to each of the plurality of available sectors during a second time slot;
wherein each coverage zone is configured for use by a respective type of equipment.
18. The apparatus of claim 17 , wherein said CBSD comprises one of a plurality of CBSDs deployed to locations proximate existing provider equipment (PE) to form thereby a multiple-node wireless network suitable for delivering networking services to subscribers.
19. The apparatus of claim 18 , wherein coverage zones of deployed CBSDs are configured to avoid interfering with coverage zones of adjacent deployed CBSDs.
20. The apparatus of claim 17 , wherein each coverage zone is configured for use in accordance with a corresponding Quality of Service (QoS) class, wherein each QoS class defines one or more of download throughput, upload throughput, and data transmission latency.
21. The apparatus of claim 17 , wherein the controller is further configured for creating a third coverage zone by transmitting a selected third PCI to each of the plurality of available sectors during a third time slot.
22. The apparatus of claim 17 , wherein transmitting one PCI from each of the plurality of available sectors uses substantially an entirety of bandwidth of the available sectors.
23. The apparatus of claim 17 , 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.
24. The apparatus of claim 23 , 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.
25. The apparatus of claim 17 , 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.
26. The apparatus of claim 23 , 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 group of WDs.
