The inventive method has taken into full account that common signal channel is single or a plurality of situation in bandwidth and the sub-district of bandwidth ability, sub-district of UE, has proposed the method for measurement cell channel under various situation.
At first, measurement is to measure discerning cell channel, for Unidentified cell channel, does not need and can not measure; So in the process of identification sub-district, some channel is not wherein measured.Such as: if the ID group of identification sub-district is to utilize synchronizing channel (synchronization Channel, SCH) identification having discerned sub-district ID group and before not discerning the sub-district, can not SCH having been measured, just can not be regarded as measured channel with it so.The present invention does not analyse in depth for this problem, and the problem of being paid close attention to that will analyze is: possible measured channel situation among the LTE.
According to the difference of practical implementation flow process, below be divided into three embodiment the inventive method is set forth in detail.
Embodiment one: the indication of network side sending measuring channel, UE measures according to the indication of being received.
The flow process of present embodiment is as shown in Figure 1, comprises the steps:
Step 101: network side is indicated to the UE sending measuring.
Said measurement indication can be system message or measurement control message.System message can be UE when being in idle condition or connection status, the message that network side issues; Measurement control message is the UE measurement control message that network side issues when being in connection status.The combination in any that can comprise following content in said system message or the measurement control message:
Measure type: comprise common frequency measurement or different-frequency measure;
Information of adjacent cells: comprise the band information of cell ID, sub-district, the centre frequency of sub-district or the combination in any of above information; Band information can be represented with initial frequency and bandwidth;
The channel that needs measurement: can be channel id, be used to identify the measured channel of needs; Measured channel can be common signal channel or CPICH Common Pilot Channel; Common signal channel can comprise SCH and/or broadcast channel (Broadcasting Channel, BCH).
Measuring amount: Es/Io, Signal to Interference plus Noise Ratio (Signal Interference Noise Ratio, SINR), the channel quality indication (Channel Quality Indicator, CQI), the combination in any of received power or above content; Wherein Es has reflected the intensity of the useful signal that receives, and Io has reflected the disturbed condition of channel; Said channel is measured exactly measured the measuring amount of channel;
Measure bandwidth information: when measured channel is CPICH Common Pilot Channel, can select this, be used to specify needs to measure the bandwidth range of CPICH Common Pilot Channel; Certainly also can not select this, UE also can confirm to need to measure the bandwidth range of CPICH Common Pilot Channel through other modes, can be elaborated below.
Step 102:UE measures the channel that needs are measured after receiving and measuring indication.
The key of this step is: which kind of metering system the channel of measuring for needs adopts, if channel is a CPICH Common Pilot Channel, then also will comprise which frequency range of measuring CPICH Common Pilot Channel.The said channel of need measuring can be a specified channel in the measurement indication that issues of network side, or the selected channel of UE, perhaps the channel of regulation in advance among the UE.
Below the process that possibly comprise to this step be elaborated:
Step 102a: confirm measured adjacent sub-district.Can adopt following any one mode or its combination:
Comprise information of adjacent cells in the Indication message of the measured channel that 102a1, network side issue, this information of adjacent cells is the information of measured adjacent sub-district, and then UE measures the pairing sub-district of information of adjacent cells; If comprise the information of adjacent cells more than in the said Indication message, then UE can therefrom select an adjacent sub-district to measure;
102a2, UE self preserve adjacent cell list, and UE selects an adjacent sub-district to measure from the adjacent cell list of self preserving.
102b: confirm measuring amount.Said measuring amount can have only one, also one group of measuring amount; Can be in the indication information that network side issues not about the information of measuring amount, UE measures the acquiescence measuring amount that is provided with in advance.For example, Es/Io is set in advance is the acquiescence measuring amount, then UE measures the Es/Io of the measured channel (possibly also comprise the bandwidth range that needs are measured) of the measured sub-district of fixed needs; Be the acquiescence measuring amount if Es/Io and SINR are set in advance, then UE measures the Es/Io and the SINR of the measured channel (possibly also comprise the bandwidth range that needs are measured) of the measured sub-district of fixed needs.
Certainly, also can comprise the information of measuring amount in the indication information that network side issues, then UE measures the measuring amount that comprises in the indication information.
