Abstract

The invention provides a frequency range notification method and a frequency range notification device. The frequency range notification method comprises the following steps of: acquiring uplink absolute channel number calculation parameterw and / or downlink absolute channel number calculation parameters, wherein the uplink absolute channel number calculation parameters include an uplink physical frequency reference value, an uplink center physical frequency point, an uplink absolute channel number reference value and a first frequency point conversion coefficient; and the downlink absolute channel number calculation parameters include a downlink physical frequency reference value, a downlink center physical frequency point, a downlink absolute channel number reference value and a second frequency point conversion coefficient; acquiring a corresponding uplink absolute channel number and / or a corresponding downlink absolute channel number according to the uplink absolute channel number calculation parameters and / or a downlink absolute channel number calculation parameters; and notifying the currently used communication frequency range by using information of the uplink absolute channel number or information of the downlink absolute channel number carried by an air interface message. By the method, a frequency range can be flexibly used and dynamically adjusted; and a frequency use demand is effectively met.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a frequency band notification method and device for an LTE system. Background technique [0002] In the LTE mobile communication system, the use of frequency resources by terminals and eNodeB network elements needs to refer to the frequency band (E-UTRA Operating Band), physical frequency (Carrier Frequency) and absolute channel number (E-UTRA Operating Band) specified in the 3GPP36.101 agreement. UTRA Absolute Radio Frequency Channel Number, referred to as EARFCN), and the mutual conversion formula between the physical frequency and the absolute channel number. For eNodeB, this conversion function needs to be used in scenarios such as organizing cell system information, organizing RRC reconfiguration measurement configuration information, handover selection target cell, etc.; for terminals, this conversion function needs to be used in cell search, initial ...
