Abstract: Methods and apparatuses are provided for searching for a cell by a communication processor (CP) of a wireless terminal having a plurality of antennas. One of the plurality of antennas is selected based on whether a secondary antenna is in a driving state and whether a finger of a rake receiver has been allocated. The plurality of antennas includes a primary antenna and the secondary antenna. A cell search is performed through the selected one of the plurality of antennas.

Abstract: A method of reducing power consumption is provided. The method includes categorizing a plurality of cells including a serving cell into an identified cell set and a non-identified cell set based on received power of the plurality of cells, measuring received power of the plurality of cells including the serving cell based on a first measurement period during a first time interval, determining whether received power of the serving cell is greater than a predefined threshold or whether a number of cells included in the identified cell set or a configuration of the plurality of cells changes, or if one of the received power of the serving cell is greater than the predefined threshold and if the number of cells included in the identified cell set or the configuration of the plurality of cells does not change, changing the first measurement period to a second measurement period.
