Description

Reference signal sending method, base station, configuration determining method and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for sending a reference signal, a method for determining configuration, and an apparatus, a base station, and a terminal thereof.
Background
In a wireless communication system, there may be a plurality of different types of reference signals that each play a different important role. There are mainly the following types of reference signals:
the first type is a Synchronization Signal, which is mainly used for Synchronization between a transmitting end and a receiving end, and includes a downlink Synchronization Signal (SS) and an uplink Synchronization Signal or a Random Access Signal (RAS); the SS may be further divided into a Primary Synchronization Signal (PSS) mainly used for synchronization of a basic time interval and a Secondary Synchronization Signal (SSs) used for alignment of sequence numbers of time interval units.
The second type is a measurement reference signal, also called measurement pilot, which is mainly used for measurement and feedback at the receiving end. According to different measurement purposes, the measurement method can be divided into mobility related measurement (RRM measurement), beam measurement (beam measurement), channel state information measurement (CSI measurement), and Large-scale properties measurement. There are mainly several types of measurement pilots:
a downlink CSI measurement pilot (CSI-RS) is mainly used for downlink CSI measurement, but may also be used for assisting in beam measurement, mobility measurement, and Large-scale characteristics measurement;
an uplink Sounding Reference Signal (SRS) is mainly used for measuring uplink channel information CSI, but may also be used for assisting in beam measurement, mobility measurement, and Large-scale properties measurement;
mobility Reference Signal (MRS), which is mainly used for Mobility-related measurements, may be an independent signal or a synchronization signal, a reference demodulation signal of a broadcast channel, or a beam measurement reference signal, and a CSI-RS signal;
a Beam Reference Signal (BRS) is mainly used for Beam training, and may also be used for Reference demodulation of a broadcast channel, mobility measurement, Large-scale properties measurement, and the like;
characteristic measurement pilot: the method is used for measuring the Large-scale properties, and comprises measurement of properties such as delay spread, Doppler spread, Doppler shift, Average gain, and Average delay, Frequency shift, Average Received power, Received Timing, channel correlation, arrival angle and the like, can be independent pilot Frequency, and can also adopt the pilot Frequency of other functions to increase the density to take the measurement of the Large-scale properties into account.
The third type is a reference demodulation signal, also called reference demodulation pilot frequency, after obtaining the channel information, the sending end can perform data/control transmission of precoding according to the channel information, and one or more layers of multi-antenna transmission technology can be adopted. Generally, each layer has a corresponding Demodulation Reference Signal (DMRS), and data or control information is demodulated by combining a received Signal with a channel estimated by the DMRS; the main use for reference demodulation includes:
reference demodulation pilot for data: for reference demodulation of a data channel, a plurality of ports may be configured; the demodulation pilot signals include reference demodulation pilot signals of uplink data and reference demodulation pilot signals of downlink data.
Controlled reference demodulation pilot: a reference demodulation for a control channel, a plurality of ports being configurable; the control channel can be divided into a special control channel and a public control channel; the private/public control channels may be divided into a plurality of subclasses according to different transmission control information, and the control channels respectively need corresponding demodulation pilot frequencies; the reference demodulation pilot frequency can be divided into uplink and downlink control according to uplink and downlink distinction.
Broadcast reference demodulation pilot: reference demodulation for broadcast channels typically only occurs downstream. The reference demodulation pilot frequency of the broadcast channel can be an independent reference demodulation pilot frequency, and can also utilize a synchronization signal or BRS to perform reference demodulation;
it should be noted that the DMRS may be used for measurement feedback of CSI (Channel State Information) in addition to demodulation.
The fourth type of pilot is a Phase Noise Compensation Reference Signal (PNCRS for short), which is also called Phase Noise estimation pilot, and is generally used for Phase Compensation when the Phase Noise is relatively large and also used for tracking frequency offset, so that the pilot may be regarded as a frequency offset estimation pilot; the pilot frequency of the type can be singly presented, and can be presented as a step of the DMRS, when the compensation of the phase noise is mainly used for the demodulation of data, the pilot frequency can also be understood as a special demodulation pilot frequency, if the pilot frequency is also defined on a transmission layer, and each layer corresponds to a port of a phase noise supplementary pilot frequency, the pilot frequency can be considered as a part of the DMRS;
in the prior art, the parameter configuration of the reference signal is generally determined by the base station and then notified to the terminal through signaling, and the common reference signal configuration includes reference signal density, time-frequency position, number of ports of the reference signal, power of the reference signal, and the like; these configurations generally use explicit signaling, that is, the time-frequency position, the port number, the power, etc. are indicated directly by status bits in the signaling. Besides these reference signal configurations, some configuration information describing the reference signal relationship also needs to be notified to the terminal, for example, a QCL (Quasi-co-location) relationship indication between reference signals, similarly a QCB (Quasi-co-beam) relationship indication or other reference signal relationship indications, a reference signal grouping indication, a merging estimation capability indication of reference signals, and the like.
It can be seen that the common feature of the above configurations is that the related configurations related to the above reference signals all relate to relationship indication information between multiple reference signals, and in the prior art, the main idea of reference signal parameter configuration is also configured by explicit control signaling, for example, explicitly notify which reference signals have relationship, and notify what relationship exists between the reference signals. The terminal determines the configuration of the parameters related to the pilot frequency relationship according to the explicit configuration signaling, and then the parameters are used for demodulation, measurement feedback and the like. Due to the fact that multiple reference signal types are involved, the number of ports of the reference signals can be large, the configuration of the ports is flexible, the relation between the reference signals is complex, some cross relations exist, some configurations are informed through an explicit signaling mode, and if enough flexibility is guaranteed, complex signaling design and a large amount of signaling overhead are needed.
In addition, in the prior art, the configuration of the reference signal is notified in an explicit manner, and there is a problem that in some cases, the terminal needs to measure the reference signal of the neighboring cell, for example, the terminal may need to measure a synchronization signal of the neighboring cell, a measurement pilot signal of the neighboring cell, and the like to determine whether a cell or a beam needs to be switched when performing mobility management. In practice, an inter-cell communication interface does not necessarily exist, and a large amount of signaling overhead is also required for configuring reference signal parameters of multiple neighboring cells, so that the explicit notification method is not suitable for all scenarios and has a large overhead.

Implementation of step 101:
in step 101, the base station may determine N reference signals, or the terminal may determine N reference signals, which correspond to the downlink reference signal and the uplink reference signal, respectively.
Optionally, the N reference signals may include reference signals of different types and/or reference signals of the same type but different time-frequency resources or different port resources.
For downlink, here N reference signals are determined by the base station, which may be some of the following:

such as "random access signal and measurement pilot signal", "random access signal and demodulation pilot signal", "measurement pilot signal and demodulation pilot signal", "phase noise pilot signal and measurement pilot signal", and the like.

the N reference signals may include some of the above or a combination thereof.
Implementation of step 111:
there are some relations for the N reference signals with respect to the multiple types of parameters, such as: characteristic parameters, sending parameters, receiving parameters, combining parameters and measuring parameters.
The characteristic parameters include: delay spread (delay spread), Doppler spread (Doppler spread), Doppler shift (Doppler shift), Average gain (Average gain), Average delay (Average delay), Frequency shift (Frequency shift), Average Received power (Average Received power) Received time (Received Timing), channel correlation (channel correlation), angle of arrival (arrival angle), angle of Departure (Departure angle), and the like.
The transmission parameters include: for the downlink, the method comprises the following steps: a transmitting cell, a transmitting sector, a transmitting base station, a transmitting antenna, a transmitting node, a transmitting precoding, a transmitting beam, a transmitting power, and the like.
The receiving parameters include: for the downlink, the method comprises the following steps: the receiving terminal, the receiving antenna, the receiving weight and the receiving beam.
The measurement parameters include: for channel measurements, for interference measurements;
there are several relationships, such as the same or different, of the reference signal parameters;
the same generally means that the parameters have the same values, such as: the density is the same, the power is the same, the period is the same, the bias is the same, etc.; the transmitting cells are the same (for downlink), the transmitting sectors are the same, the transmitting base stations are the same (for downlink), the transmitting terminals are the same (for uplink), the transmitting antennas are the same, the transmitting nodes are the same, the transmitting precoding is the same, and the transmitting beams are the same; the receiving terminals (for downlink) are the same, the receiving base stations (for uplink) are the same, the receiving cells (for uplink) are the same, the receiving antennas are the same, the receiving weights are the same, the receiving beams are the same, and the receiving modes are the same;
different values refer to the situation where the above parameters have different values.
The relationship of the reference signal parameters can also be described as: correlated, uncorrelated;
some characteristic parameters may be related, such as the same frequency offset, the same time offset, the same angle of arrival, the same angle spread, and so on; or some transmission parameters may be related, such as transmission precoding, transmission beam, transmission power, etc.; or some reception parameters may be related, such as reception precoding, reception beam, etc. Quasi co-location or quasi co-beam is generally a specific expression describing the correlation of reference signals.
The correlation may be identical, may be relatively similar, or may have a correlation, which is generally weaker than the same requirement; the same is a special case of relevance.
Irrelevant is a different special case, i.e. different and without relevance; the parameters may be considered independent of each other.
The relationship of the reference signal parameters can also be described as: mergeable, not mergeable;
for example, some signals may be combined for demodulation, for phase noise estimation, for channel measurement, for synchronization, for signature measurement, for interference measurement, etc.; some signals cannot be combined for phase noise estimation, channel measurement, synchronization, characteristic measurement, and interference measurement.
The relationship of the reference signal parameters can also be described as: combinable, non-combinable;
combining is a special case of combining, and in some cases, although combining is not direct, due to certain correlation between the two, noise reduction can be performed jointly to improve channel estimation performance, channel measurement accuracy, phase noise estimation performance, synchronization performance, characteristic measurement accuracy, interference measurement accuracy and the like.
Implementation of step 121:
specifically, the base station or the terminal may determine the transmission sequences of the N reference signals.
The determination of the transmission sequences needs to be determined according to the aforementioned relationship between the N reference signals and the M-class parameters, and the relationship between the transmission sequences of the N reference signals can embody the relationship existing between the N reference signals and the M-class parameters; that is, the relationship that exists between sequences implicitly characterizes the relationship between the M-class parameters.
For example, if the sequences belong to the same set (sequence group), the sequences represent that there is an association relationship with respect to one or more types of parameters in the M types of parameters; more specifically, the sequences may belong to the same sequence set, and represent that different reference signals have a quasi-co-location relationship with respect to one or more characteristic parameters corresponding to the set; the sequences belong to the same sequence set and represent that different reference signal sending cells are the same; the sequences belong to the same sequence set, and represent that different reference signal sending sectors are the same; the sequences belong to the same sequence set, and represent that different reference signal sending base stations are the same; the sequences belong to the same sequence set and represent that different reference signal sending terminals are the same; the sequences belong to the same sequence set and represent that different reference signal transmitting antennas are the same; the sequences belong to the same sequence set, and represent that different reference signal sending nodes are the same; the sequences belong to the same sequence set and represent that different reference signals are sent with the same or related precoding; the sequences belong to the same sequence set and represent that different reference signal transmitting beams are the same or related; the sequences belong to the same sequence set and represent that the sending powers of different reference signals are the same or related; the sequences belong to the same sequence set and represent the same reference signal receiving terminal; the sequences belong to the same sequence set and represent that different reference signal receiving base stations are the same; the sequences belong to the same sequence set and represent that different reference signal receiving cells are the same; the sequences belong to the same sequence set and represent that different reference signal receiving sectors are the same; the sequences belong to the same sequence set and represent that different reference signal receiving antennas are the same; the sequences belong to the same sequence set and represent that different reference signal receiving weights are the same or related; the sequences belong to the same sequence set and represent that different reference signal receiving beams are the same or related; the sequences belong to the same sequence set, and different reference signals can be jointly used for channel measurement; the sequences belong to the same sequence set, and different reference signals are represented to be jointly used for interference measurement; the sequences belong to the same sequence set, and different reference signals are characterized to be jointly used for phase noise estimation; the sequences belong to the same sequence set, and different reference signals can be jointly used for demodulation/coherent reception; the sequences belong to the same sequence set, and different reference signals can be jointly used for time domain/frequency domain synchronization.
It is also possible to characterize the relationship of the reference signals using sequence correlation; for example, if the sequence correlation coefficient is greater than an agreed or configured threshold, it is considered to be correlated or the same with respect to one or more types of parameters; or may be combined and combinable.
The relation of the reference signal can also be characterized by the relation of the root sequence index; for example, if the index satisfies the agreed functional relationship, it is considered that the parameters related to one or more types are related or the same; or may be combined and combinable.
The relation of the reference signals can be represented by the relation of cyclic shift values; for example, if the cyclic shift values are the same, the cyclic shift values are considered to be related or the same with respect to one or more types of parameters; or may be combined and united.
The relationship of the reference signal can also be characterized by using an orthogonal code; for example, if the orthogonal codes are the same, the codes are considered to be related or the same about one or more types of parameters; or may be combined and combinable.
The relation of the reference signal can also be represented by using the scrambling code; for example, if the scrambling codes are the same, the parameters related to one type or multiple types are considered to be related or the same; or may be combined and combinable.
Example 2
In step 121, as mentioned in the foregoing embodiment, the rule that the transmitting end determines to use the sequence to indicate the different reference signal relationships may generally be predetermined by the transmitting and receiving ends; or the sending end determines and then configures the data to the receiving end; or the receiving end determines and configures the data to the transmitting end.
The rule may be different for different reference signals, and for example, the configuration of the sequence set may be:
configuring X sequence sets for the synchronous signals, wherein the sequence sets are respectively X sequence sets 1 ，X 2 ……X x ；
Configuring Y sequence sets for measurement pilot frequency, wherein the sequence sets are respectively a sequence set Y 1 ，Y 2 ……Y y ；
Configuring Z sequence sets for demodulation pilot frequency, wherein the sequence sets are respectively a sequence set Z 1 ，Z 2 ……Z z ；
That is, after the reference signal type is determined, the above reason sequence is determined to indicate the rule of different reference signal relationships.
In addition, the rules corresponding to different parameters are also different, and taking the configuration of the sequence set as an example, the following may be used:
configuring a sequence sets for the time bias parameters, wherein the sequence sets are respectively a sequence set A 1 ，A 2 ……A a ；
B sequence sets are configured for the frequency offset parameter, and are respectively a sequence set B 1 ，B 2 ……B b ；
C sequence sets are configured for the power parameters, and are respectively a sequence set C 1 ，C 2 ……C c ；
D sequence sets are configured for sending cell parameters, and are respectively a sequence set D 1 ，D 2 ……D d ；
E sequence sets are configured for the transmission beam parameters, and are respectively a sequence set E 1 ，E 2 ……E e ；
Configuring F sequence sets for receiving beam parameters, wherein the F sequence sets are respectively sequence sets F 1 ，F 2 ……F f ；
The set of sequence sets configured for different types of parameters may be different.
Similarly, if the relation of the reference signals with respect to the M-class parameter types is implicitly indicated by the functional relation of the sequences, the functional relation of the sequences may be different for different types of reference signals.
Similarly, if the relation of the reference signal with respect to the M-class parameter type is implicitly indicated by the functional relation of the sequences, the functional relation of the sequences may be different for different types of reference signal parameters.
An embodiment of the present invention further provides a computer-readable storage medium, which stores computer-executable instructions, and when executed, the computer-executable instructions implement the method for transmitting the reference signal.
