First Claim
1. A transceiver device, comprising:
- a receiver capable of identifying at least one neighbor cell of a wireless network in which the transceiver device is located, the receiver capable of identifying the at least one neighbor cell by detecting a synchronization signal of the at least one neighbor cell and capable of measuring a received signal power from the at least one neighbor cell; and
transmitter capable of communicating to a network entity of the wireless network identifying information and the received signal power of the at least one neighbor cell, wherein the network entity determines if the transceiver device is isolated from the at least one neighbor cell based at least on the measured received signal power from the at least one neighbor cell,the receiver being further capable of receiving from the network entity information indicating whether dynamic uplink-downlink reconfiguration can be enabled of the allocation of uplink and downlink subframes used in the cell in which the transceiver is located, wherein dynamic uplink-downlink reconfiguration is enabled if the transceiver device is isolated from the at least one neighbor cell and dynamic uplink-downlink reconfiguration is disabled if the transceiver device is not isolated from the at least one neighbor cell, the information received from the network entity indicating the reconfiguration can be enabled of the allocation of uplink and downlink subframes used in the cell, andthe transceiver device further comprising a processor capable of reconfiguring the allocation of uplink and downlink subframes used in the cell.

Abstract
At least one neighbor cell is identified by a base station by detecting a synchronization signal of the at least one neighbor cell. A received signal power, such as a Reference Signal Received Power (RSRP) or a Reference Signal Received Quality (RSRQ), or a combination thereof, is also measured from the at least one neighbor cell. Identifying information and the received signal power of the at least one neighbor cell is then communicated to a network entity of the wireless network. Information is received from the network entity indicating whether the base station can enable a reconfiguration of the allocation of uplink and downlink subframes used in the cell of the base station. Based on the information received from the network entity, the base station enables a reconfiguration of the allocation of uplink and downlink subframes used in the cell.
