Abstract

A method and apparatus for transmitting a ChannelMeasurementReport message in a wireless communication system, comprising generating a ChannelMeasurementReport message comprising a 8 bit MessageID field, a 12 bit PilotPN field that indicates the PilotPN of a sector for which a measurement was performed, a 2 bit CarrierID field that indicates a carrier on which the measurements are performed, a 40 bit StartPHYFrameNumber field that indicates a frame number of a PHYFrame where an access terminal made a first measurement reported in the message, a 8 bit MeasurementInterval field that indicates a number of PHYFrames between measurements made by the access terminal, and a 8 bit NumMeasurements field that indicates number of measurements included in the message and transmitting the ChannelMeasurementReport message over a communication link. A method and apparatus is also provided for receiving and processing the ChannelMeasurementReport message.
