Title:
METHOD AND SYSTEM FOR MEASURING AND REPORTING RECEIVED SIGNAL STRENGTH
Document Type and Number:
WIPO Patent Application WO2001022600
Kind Code:
A3
Abstract:
In a Time Division Multiple Access based radio telecommunications system that employs downlink power control, received signal strength information is measured and reported. A downlink data signal is transmitted from a base station to a mobile station during a first timeslot. A control channel signal or a dedicated traffic channel signal having equivalent output power behavior as the control channel, is transmitted from the base station throughout a cell in which the mobile station is operating. At the mobile station, a received signal strength of the control channel signal or the dedicated traffic channel signal is measured. The received signal strength may be measured in period between when the mobile station transmits and receives or in a period between when the mobile station received and transmits. The received signal strength may be measured during the first timeslot or during a timeslot other than said first timeslot. The received signal strength may also be measured during a time period associated with Mobile Assisted Handover (MAHO) measurements, the MAHO list including the control channel and/or the dedicated traffic channel. The received signal strength as measured by the mobile station is reported to the base station. The measured received signal strength is compensated for to obtain signal strength information associated with the downlink data signal received by the mobile station during the first timeslot.
