Abstract
Disclosed are systems and methods for dynamic power regulation in small cells. In one aspect, a system is configured to determining at least one mobility metric indicative of at least one access terminal mobility at the cell. The system then configured to determine whether the value of mobility metric is acceptable. When the value of mobility metric is unacceptable, the system is configured to increase the transmit power of the cell until the value of mobility metric becomes acceptable. If the value of mobility metric does not become acceptable after increasing the transmit power of the cell above a threshold, the system is configured to decrease the transmit power of the cell.
Claims21
A method for regulating transmit power of a small cell, comprising:
- determining a value of at least one mobility metric indicative of at least one access terminal mobility at the cell;
- determining whether the value of the at least one mobility metric is acceptable;
- in response to determining that the value of the at least one mobility metric is unacceptable, increasing the transmit power of the cell;
- determining a value of at least one interference metric indicative of interference experienced by at least one access terminal at the cell;
- determining whether the value of the at least one interference metric is acceptable after increasing the transmit power of the cell;
- and
- in response to determining that the value of the at least one interference metric is unacceptable and the value of the at least one mobility metric is acceptable, decreasing the transmit power of the cell while the value of the at least one mobility metric remains acceptable.
An apparatus for regulating transmit power of a small cell, comprising:
- a memory configured to store data;
- and
- at least one processor communicatively coupled to the memory, the at least one processor being configured to execute instructions to process the data in the memory to:
- determine a value of at least one mobility metric indicative of at least one access terminal mobility at the cell;
- determine whether the value of the at least one mobility metric is acceptable;
- in response to determining that the value of the at least one mobility metric is unacceptable, increase the transmit power of the cell;
- determine a value of at least one interference metric indicative of interference experienced by at least one access terminal at the cell;
- determine whether the value of the at least one interference metric is acceptable;
- and
- in response to determining that the value of the at least one interference metric is unacceptable and the value of the at least one mobility metric is acceptable, decrease the transmit power of the cell while the value of the at least one mobility metric remains acceptable.
An apparatus for regulating transmit power of a small cell, comprising:
- means for determining a value of at least one mobility metric indicative of at least one access terminal mobility at the cell;

- means for determining a value of at least one interference metric indicative of interference experienced by at least one access terminal at the cell;
- means for determining whether the value of the at least one interference metric is acceptable;
- and
- means for decreasing the transmit power of the cell while the value of the at least one mobility metric remains acceptable in response to determining that the value of the at least one interference metric is unacceptable and the value of the at least one mobility metric is acceptable.
A non-transitory computer readable medium storing computer executable code for regulating transmit power of a small cell, comprising:
- code for determining a value of at least one mobility metric indicative of at least one access terminal mobility at the cell;
