PCI PARTITION AND ALLOCATION FOR CELLULAR NETWORK

摘要

Generally discussed herein are systems and apparatuses that can implement Physical Cell Identity assignments that reduce collision or confusion of small cell identities at User Equipment and techniques for using the same. According to an example apparatus a device can be configured to estimate a location of the small cell eNodeB based on at least one of Global Positioning System (GPS) coordinates of the location of the small cell eNodeB and an RSRP measured at the small cell eNodeB, determine if the location of the small cell eNodeB is within a first region or a second region of a large cell transmission area, wherein the first and second regions do not overlap, and in response to determining which region the small cell eNodeB is deployed in, assign a PCI code from a respective group of available PCI codes to the small cell eNodeB.

1. A Long Term Evolution (LTE) device configured to assign a Physical Cell Identity (PCI) code to a small cell eNodeB based on a location of the small cell eNodeB, wherein the LTE device is configured to:
estimate a location of the small cell eNodeB based on at least one of Global Positioning System (GPS) coordinates of the location of the small cell eNodeB and an RSRP measured at the small cell eNodeB; determine if the location of the small cell eNodeB is within a first region or a second region of a large cell transmission area, wherein the first and second regions do not overlap; in response to determining the small cell eNodeB is within the first region, assign a PCI code from a first group of available PCI codes to the small cell eNodeB; and in response to determining the small cell eNodeB is within the second region, assign a PCI code from a second group of available PCI codes to the small cell eNodeB, wherein the first group of PCI codes and the second group of PCI codes are disjoint.
