Managing power consumption in base stations and remote access points
A wireless transmit/receive unit (WTRU) in communication with a wireless network that may include a base station (or base node) and a cell that may be in a dormant mode is contemplated. The WTRU may determine that the WTRU may be within a vicinity of the cell and may generate a report that includes one or more measurements related to a location of the WTRU. The WTRU may transmit the report to the network and may receive an indication to perform one or more measurements related to the cell. The one or more measurements related to the cell may be based on a Common Pilot Channel (CPICH), a Synchronization Channel (SCH), and/or a Broadcast Channel (Primary Common Control Physical Channel) (BCH P-CCPCH) that may be transmitted by the cell upon a command from a base node.
1. A base node, the base node being in communication with a wireless network, the base node comprising:
a processor, the processor configured to:
provide a first indication to a cell in a dormant mode, the first indication directing the cell to exit the dormant mode;
receive a second indication that the cell has exited the dormant mode;
provide a third indication to a wireless transmit/receive unit (WTRU) to generate at least one report, the at least one report including measurement results for the cell, the measurement results for the cell related to a location of the WTRU relative to the cell;
receive the at least one report from the WTRU;
determine a handover condition based at least in part on the at least one report; and
provide a fourth indication to the cell based at least in part on the handover condition, the fourth indication causing the cell to enter an active mode.
2. The base node of claim 1 , wherein the first indication to the cell includes a WAKE-UP Common Pilot Channel (CPICH) message, the WAKE-UP CPICH message causing the cell to transmit at least one of the CPICH or a Broadcast Channel (Primary Common Control Physical Channel) (BCH P-CCPCH).
3. The base node of claim 2 , wherein the WAKE-UP CPICH message causes the cell to transmit the at least one of the CPICH or a Broadcast Channel (Primary Common Control Physical Channel) (BCH P-CCPCH) for a period of time.
