Problems solved by technology

However, the power of the signal sent on the CPICH may not be a good indicator of the power of the signal sent on the MTCH (which actually carries MBMS application data)
One reason for this is that power control is not used on the S-CCPCH for example

Abstract

Cells from which to receive information transmitted on a traffic channel that is not subject to power control in a cellular radio communications system are selected. Selection involves, for each of a plurality of candidate cells, using an offset value that indicates a relationship between a pilot channel transmission power and the traffic channel transmission power associated with the candidate cell to determine a value of quality indicative of power of a signal transmitted on the traffic channel associated with the candidate cell; and selecting, based on the values of quality indicative of power of a signal transmitted on the traffic channel, a number, N, of cells from the plurality of candidate cells.

Description

Technical field [0001] The present invention relates to a communication device, and more specifically, the present invention relates to a communication device that receives multiple copies of the same information sent from different transmitters. Background technique [0002] Digital communication systems include: Time Division Multiple Access (TDMA) systems, such as cellular radio telephone systems that comply with the GSM telecommunication standard and their enhanced versions (such as GSM / EDGE), and Code Division Multiple Access (CDMA) systems, such as IS-95, cdma2000 and Wideband CDMA (WCDMA) telecommunications standard cellular radio telephone system. Digital communication systems also include "hybrid" TDMA and CDMA systems, such as cellular radio telephone systems that comply with the Universal Mobile Telecommunications System (UMTS) standard, which stipulates that the European Telecommunications Standards Institute (ETSI) The third generation (3G) mobile system developed w...
