摘要: Methods and apparatus for changing cell range coverage are disclosed. The may be changed on a per-sub-frame basis. An antenna beam elevation tilting angle adjusted to provide different effective downlink (DL) coverage. For example, subframe small tilt or large subframe. A network evolved NodeB (eNB) determine data channel transmission power adjust per Low Power Subframe (LPS) used alone with Almost Blank (ABS) transmit data. Timing Advance (TA) handling uplink (UL) transmissions is described. common TA (CTA) determined multi-site UL signaling. control multiple sites. Radio Link Monitoring (RLM) performed sites carrier frequency. wireless transmit/receive unit (WTRU) maintain synchronization in selected subframes cells.
