EFFICIENT PHYSICAL CELL IDENTIFIER COLLISION AND CONFUSION AVOIDANCE USING LTE-DIRECT |
摘要 |
The disclosure generally relates to avoiding physical cell identifier (PCI) collision and confusion using LTE-Direct expressions. In particular, a small cell may discover LTE-Direct expressions that include PCIs associated with neighbor small cells and select (or reselect) a local PCI to ensure that the local PCI differs from the PCIs associated with each neighbor small cell. Furthermore, the small cell may detect PCI confusion where multiple neighbors broadcast LTE-Direct expressions with the same PCI and different E-UTRAN Cell Global Identifiers (eCGIs) and/or detect PCI confusion in neighbor small cells where the local PCI matches the PCI used in a neighbor's neighbor and the local eCGI used in the small differs from that used in the neighbor's neighbor. The small cell may additionally broadcast LTE-Direct expressions that include at least the local PCI and eCGI to enable neighbors to avoid PCI collision and confusion in the same manner. |
