Description

The method of determining and terminal is configured in reference signal sending method and base station
Technical field
The present invention relates to field of communication technology more particularly to a kind of sending method of reference signal, the determining methods of configuration And its device, base station and terminal.
Background technology
It in a wireless communication system, can there are a variety of different types of reference signals, these reference signals to carry respectively Different aspect important role.It is primarily present following a few class reference signals：
The first kind is synchronizing signal, synchronizing signal be mainly used for it is synchronous between transmitting terminal and receiving terminal, it is same including downlink Walk signal (Synchronization Signal, abbreviation SS) and uplink synchronizing signals or accidental access signal (Radom Access signal, abbreviation RAS)；Wherein, SS can further be divided into primary synchronization signal (primary Synchronization signal, abbreviation PSS) and secondary synchronization signal (secondary synchronization signal, Abbreviation SSS), the former is mainly used for basic time interval synchronization, and the latter is used for the alignment of time interval unit number.
Second class is measuring reference signals, also known as measures pilot tone, is mainly used for measurement and the feedback of receiving terminal.According to survey It is different to measure purpose, mobility measurement of correlation (RRM measurement) can be divided into, wave beam measures (beam Measurement), channel state information measures (CSI measurement), and Large-scale properties are measured.It is main There is the measurement pilot tone of following several types：
The CSI of downlink measures pilot tone (channel state information reference signal, abbreviation CSI- RS), be mainly used for downlink channel information CSI measure, but can also assist for wave beam measure, mobility measurements and Large-scale properties (large scale characteristic) are measured；
The detecting pilot frequency (sounding reference signal, abbreviation SRS) of uplink is mainly used for the channel of uplink Information CSI is measured, but can also assist measuring for wave beam, and mobility measurements and Large-scale properties are surveyed Amount；
Mobility measurements pilot tone (Mobility reference signal, abbreviation MRS) is mainly used for mobility correlation Measurement, it may be possible to independent signal is it could also be possible that synchronizing signal, the reference demodulated signal or wave beam of broadcast channel are surveyed Measure reference signal and CSI-RS signal；
Wave beam measures pilot tone (Beam Reference Signal, abbreviation BRS), is mainly used for wave beam training, can also use It is demodulated in the reference of broadcast channel, mobility measurements, Large-scale properties are measured etc.；
Feature measurement pilot tone：It is measured for Large-scale properties, including delay spread, Doppler Spread, Doppler shift, average gain, and average delay, Frequency shift, Average The properties such as received power, Received Timing, channel correlation, arrival angle Measurement, can be independent pilot tone or increase density using the pilot tone of other functions and take into account Large-scale The measurement of properties.
Third class is with reference to demodulated signal, and also known as with reference to demodulation pilot tone, transmitting terminal can root after channel information is obtained The transmission of data/control of precoding is carried out according to channel information, one or more layers multiple antenna transmission technique may be used.Generally For, each layer has corresponding demodulation reference pilot tone (Demodulation Reference Signal, abbreviation DMRS), number According to or control information the signal received is combined by channel that demodulation reference pilot tone estimates and be demodulated；It is mainly used for joining Demodulation is examined to include：
The reference demodulation pilot tone of data：It is demodulated for the reference of data channel, multiple ports can be configured；Including upper line number According to reference demodulation pilot tone and downlink data reference demodulation pilot tone.
The reference demodulation pilot tone of control：It is demodulated for the reference of control channel, multiple ports can be configured；Control channel is again Proprietary control channel, publicly-owned control channel can be divided into；Proprietary/publicly-owned control channel can may control information according to transmission again Difference is divided into multiple subclasses, these control channels are respectively necessary for corresponding demodulation pilot tone；Being distinguished according to uplink and downlink can be divided into again, The reference demodulation pilot tone of the control of uplink and downlink.
Broadcast is with reference to demodulation pilot tone：It is demodulated for the reference of broadcast channel, is generally only present in downlink.The ginseng of broadcast channel It can be independent reference demodulation pilot tone to examine demodulation pilot tone, can also be carried out using synchronizing signal or BRS with reference to demodulation；
It should be noted that DMRS can be used for CSI (Channel in addition to being used to demodulate in the case of having State Information, channel status instruction) measurement feedback.
4th class pilot tone is phase noise estimation reference signal (Phase Noise Compensation Reference Signal, abbreviation PNCRS), estimating pilot frequency of also known as mutually making an uproar, this kind of pilot tone be generally used for phase noise it is bigger when phase Compensation, can be used for the tracking of frequency deviation, it will also be appreciated that being offset estimation pilot tone；The situation that this kind of pilot tone has is single Solely occur, situation be then to separate existing as a step of DMRS, the compensation of mainly phase noise is mainly used for the solution of data Timing, it can be appreciated that special demodulation pilot tone, if it is also defined in transport layer, one phase of every layer of correspondence is made an uproar If the port of sound supplement pilot tone, it may be considered that the part as DMRS；
In the prior art, the parameter configuration of above-mentioned reference signal is typically all then base station is determined by signaling To terminal, common reference signal configuration includes reference signal density and time-frequency location, the port number of reference signal, reference Power of signal etc.；These configurations generally use the configuration mode of explicit signaling, that is to say, that directly pass through the state in signaling Position indicates time-frequency location, port number, power etc..Other than these reference signal configurations, also some descriptions are with reference to letter The configuration information of number relationship, it is also desirable to notify to terminal, for example, between reference signal QCL (Quasi-co-location, it is accurate Position altogether) relationship instruction, similar also has relationship between the instruction of QCB (quasi-co-beam) relationship or other reference signals to indicate, Reference signal grouping instruction, combining estimate ability instruction of reference signal etc..
It can be found that the common feature of some of the above configuration is to relate to the relevant configuration of above-mentioned reference signal to be directed to Relationship instruction information between multiple reference signals, in the prior art, the main thinking of reference signal parameter configuration is also logical Explicit control signaling is crossed to be configured, for example, explicitly notifying which reference signal there are relationship and notifying these with reference to letter There are what relationships between number.Terminal determines the configuration of these pilot tone relationship relevant parameters according to explicit configuration signal, then For demodulating, measuring feedback etc..Due to being related to a variety of reference signal types, the port number of reference signal may also be very More, the configuration of port is also flexibility and changeability, and the relationship between reference signal is also more complicated, and there are some cross references, Some configurations above are notified, and if ensureing enough flexibilities by explicit signaling method, are needed complicated Signalling Designing and a large amount of signaling overheads.
In addition to this, it in the prior art by explicit mode come the configuration of notification reference signal, there is also an issue It is that terminal needs to measure the reference signal of adjacent cell, for example terminal may need to measure neighbour in mobile management in the case of having To determine whether needing switching cell or wave beam, this mode needs for the synchronizing signal of cell, measurement pilot signals of adjacent cell etc. Serving cell is wanted to communicate by the interface of minizone, then the relevant reference signal configuration of adjacent cell pilot tone is notified to originally small The terminal in area.And actually inter-cell communication interface is not necessarily reference signal ginseng existing, and that multiple adjacent cells are configured Number is also required to a large amount of signaling overheads, therefore this explicit notification method can not be suitable for all scenes, and expense is big.
