Method, base station and terminal.
Background technique
Terminal device UE is based on cell reference symbols (CRS) and carries out RRM (Radio in existing LTE (long term evolution) technology
Resource Management, wireless resource management) measurement, the cell quality RSRQ reported by UE measurement
(ReferenceSignalReceivingQualit, Reference Signal Received Quality), supplementary cell switches over judgement and movement
Property management.
CRS is that full bandwidth is sent in LTE, in order to reduce the expense of reference symbol, in 5G will there is no CRS, therefore not
Need to be replaced the measurement function of CRS with other reference signals.One of possible mode is carried out using synchronizing symbol
Measurement.Synchronizing symbol and Physical Broadcast Channel PBCH are (same in SS block as shown in Figure 1: for the sending method of synchronizing symbol in 5G
Walk block) in transmission, periodicity sending includes in each SS block: primary synchronization signal PSS, secondary synchronization signal SSS and wide
Broadcast channel PBCH, mapping mode PSS-PBCH-SSS-PBCH.Wherein PSS-PBCH-SSS-PBCH respectively accounts for 1 OFDM symbol,
I.e. each SS block occupy in the time domain 4 OFDM (Orthogonal Frequency Division Multiplexing,
Orthogonal frequency division multiplexi) symbol, wherein PSS and SSS accounted on frequency domain 12 PRB (physical resource block,
Physical Resource Block), PBCH accounts for 24 PRB on frequency domain.
Reference Signal Received Quality RSRQ is defined as follows in LTE at present:
Wherein, RSRP (Reference Signal Receiving Power, Reference Signal Received Power) is with reference to symbol
The available signal power measured on number CRS characterizes cell signal strength；RSSI(Received Signal Strength
Indication, received signal strength indicator) be comprising reference symbol CRS OFDM symbol on general power, contain data
With useful signal, interference and the noise of reference signal；N is the number of the resource block RB in rssi measurement bandwidth.
According to the definition of RSRQ as can be seen that containing the RE of reference signal in the measurement of the denominator RSSI of RSRQ
The RE of (Resource Element, resource particle) and data channel, therefore serving cell is embodied in measurement amount and target is small
The influence of area's load.
System bandwidth is larger in 5G, and maximum can be 400MHz.Although UE measures the position SS block (24 PRB)
The signal quality of synchronization signal and data, but SS block will not occupy all resource block RB on frequency domain, when actually cutting
After the completion of changing, UE other frequency domain positions that may be scheduled carry out data transmission.In this case, UE is practical small in target
The previously measured signal quality of signal quality and UE in area may differ greatly, therefore survey of the UE to the SS block of the cell
It is little in the reference significance of the signal quality of the cell for UE to measure result.
