A method and system are disclosed for determining load on a microcell in a telecommunications network. The network comprises a base station, at least one microcell controlled by the base station, at least one terminal served by the mi crocell, and feedback between the base station and the terminal. The feedback enables the terminal to provide an up-link signal indicative of a particular down-link signa l from the microcell. The method embodiment of the invention involves transmitting a partic ular down-link signal from the microcell, and receiving an up-link signal from a term inal. Next, a determination is made whether the up-link signal is indicative of the pa rticular down-link signal. If it is, then the load on the microcell includes the terminal . The method and system are particularly useful in CATV networks having a plurality of microcells operating in a simulcast mode. In one preferred embodiment, the micro cell transmits the particular down-link signal in a certain pattern, if the up-link s ignals of the terminal reflect the pattern of the particular down-link signal, then its load o n the microcell is confirmed. Once the load of a microcell is determined, then the net work may be optimized for capacity and quality. In one embodiment, optimization is performed by altering the RF carrier among the microcells to balance load in the network.
