Abstract

The present invention provides a pilot frequency measurement method and device. The method comprises the steps of: obtaining working frequency point information of a pilot frequency adjacent region ofa terminal and wave beam polling intervals of sending reference symbols by the pilot frequency adjacent region; according to the wave beam polling intervals of sending the reference symbols by the pilot frequency adjacent region, determining pilot frequency measurement intervals of sending the reference symbols by the pilot frequency adjacent region; and performing frequency modulation in the pilot frequency measurement intervals to the working frequency point of the pilot frequency adjacent region to receive the reference symbols sent by the pilot frequency adjacent region, and performing pilot frequency measurement according to the reference symbols. In the embodiment of the invention, measurement information sent by a service cell to the terminal carries the working frequency point information of the pilot frequency adjacent region and carries the wave beam polling intervals of sending reference symbols by the pilot frequency adjacent region to allow the terminal to dynamically determine different pilot frequency measurement intervals according to different wave beam polling intervals and namely allow the terminal to receive all the reference symbols sent by the pilot frequencyadjacent region in the pilot frequency measurement intervals, and therefore transmission of other data cannot be influenced by too long pilot frequency measurement intervals, and system performancesare improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an inter-frequency measurement method and device. Background technique [0002] When the existing terminal performs inter-frequency measurement, if the terminal’s radio frequency capability is limited, it needs to interrupt the connection with the current service frequency point for a period of time, including interrupting the transmission and reception of data services with the serving cell and possible same-frequency measurement, and frequency adjustment to the test frequency Frequency points for inter-frequency measurement. This interruption time is the measurement interval (measurement gap). In the existing LTE solution, since the synchronization symbol transmission interval is 5ms, the measurement gap length is 6ms, of which 1ms is used for frequency modulation, and the remaining 5ms is used for cell access and measurement. The start position of the ...
