Description

Phase noise estimation method and equipment

Technical field

This application involves field of communication technology more particularly to a kind of phase noise estimation methods and equipment.

Background technique

In a wireless communication system, phase noise (Phase Noise, PN) is the random short-term wave in wireless signal phase Dynamic bring noise, phase noise makes wireless signal that phase Random-Rotation occur in the time domain, so that wireless signal be brought to exist Common phase mistake (Common Phase Error, CPE) and inter-carrier interference (Inter Carrier on frequency domain Interference, ICI), and then influence the reception of wireless signal.Phase noise is usually by terminal device and access network equipment The devices such as crystal oscillator cause.Since terminal device is restricted by cost and volume, the crystal oscillator parameter specification used is poor, It is more prone to produce phase noise；And in contrast, the cost and volume of access network equipment are not restricted in a certain range, therefore Used crystal oscillator is with a higher standard.It therefore is usually that phase noise estimation is carried out to the Anneta module of terminal device.The antenna mould Block includes at least one physical antenna elements, and each physical antenna elements include the devices such as crystal oscillator.Phase noise is estimated important Means seek to that the pilot tone for phase noise estimation is added in wireless signal, which is referred to as Phase Tracking reference signal (Phase Tracking Reference Signal, PTRS).

By taking downlink data transmits as an example, in order to which the channel to transmission wireless signal estimates that access network equipment would generally Demodulated reference signal (Demodulation Reference signal, DMRS) is carried in wireless signal.Net is generally accessed to set Standby upper DMRS port is corresponding with the port PTRS, with realize PTRS to be used to receive in terminal device the Anneta module of DMRS into The estimation of row phase noise.And the quantity of the port PTRS is equal to the quantity of the independent crystal oscillator of terminal device, the quantity of DMRS port Depending on the number of data streams for needing to transmit, (a data flow stream can also be referred to as a transport layer layer).? In multiple-input and multiple-output (Multiple-Input Multiple-Out, MIMO) transmission mode, access network equipment can simultaneously to Terminal device sends multiple data flows (also referred to as multilayer transmission), and each data flow corresponds at least one DMRS port.Usually The quantity of DMRS port is greater than the quantity of the port PTRS.Accordingly, it is possible to which can have DMRS port does not have the corresponding port PTRS Problem.

In order to solve this technical problem, the prior art provides following technical solution: Fig. 1 be the prior art provide when Frequency resource map, as shown in Figure 1, wherein horizontal axis represents the time, is that basic time is single with single symbol (symbol) Position, vertical coordinate axle represent frequency, with a subcarrier (sub-carrier) for basic frequency unit.One subcarrier and one The temporal frequency group substantially of a symbol composition is collectively referred to as resource element (Resource Element, RE).It illustrates in figure one In the time of a subframe (including 14 symbols), in the frequency domain of 24 subcarriers, the running time-frequency resource point when 4 layers of downlink data is sent Cloth situation.What is sent in the 0th~1 symbol is downgoing control signal.2nd symbol sends DMRS, and 4 layers of downlink data need 4 A DMRS port, such as: DMRS port 0 is used for transmission data flow 0, and DMRS port 1 is used for transmission data flow 1, and DMRS port 2 is used In transmitting data stream 2, DMRS port 3 is used for transmission data flow 3.Wherein DMRS port 0 and DMRS port 2 use frequency division multiplexing side Formula, DMRS port 1 and DMRS port 3 also use frequency division multiplexing mode.DMRS port 0 and DMRS port 1 use code division multiplexing side Formula, DMRS port 2 and DMRS port 3 also use code division multiplexing mode.Line number under being that 3rd symbol is sent to the 13rd symbol According to.Usual PTRS only takes up a subcarrier in frequency, but occupies continuous 11 symbols in the time domain.The wherein port PTRS 0 and DMRS port 0 it is corresponding, the port PTRS 1 and DMRS port 3 are corresponding.Since DMRS port 0 and DMRS port 1 are multiple using code point A running time-frequency resource is shared with mode, is likely on space antenna using polarization multiplexing mode, it can be by DMRS port 0 It is known as a DMRS port group with DMRS port 1, DMRS port 0 and DMRS port 1 are considered as the quasi- co-sited (Spatial in space QuasiCoLocation, QCL).DMRS port 2 and DMRS port 3 are known as a DMRS port group, their spaces each other QCL.It will also be appreciated that the port PTRS 0 and DMRS port 1 are corresponding；The port PTRS 1 is it is also assumed that right with DMRS port 2 It answers.

The case where quantity that may have the port PTRS in the prior art is less than the quantity of DMRS port group.For example, if Access network equipment scheduled 8 layers of most downlink data transmission of Single User MIMO, wherein polarization multiplexing two-by-two, then need 4 DMRS port group (totally 8 DMRS ports) sends DMRS.If terminal device is only configured with two ports PTRS.It is so inevitable There are two DMRS port groups not to have the corresponding port PTRS, is based on this, will be unable to the two corresponding days of DMRS port group Wire module carries out phase noise estimation, to reduce the reliability of data transmission.

Specific embodiment

Third generation partner program (3rd Generation Partnership Project, 3GPP) is for the 5th generation The design object of mobile communication technology (5Generation, 5G) is to develop at least up to 100 gigahertz (GHZ)s (Giga Hertz, GHz) Frequency range, and the phase noise power spectrum density of Anneta module (for example is mentioned with the every 11-fold increase of carrier frequency from 3GHz carrier wave Height arrive 30GHz carrier wave) just will increase 20 decibels (Decibel, DB), this also mean that the high frequency section of 5G system signal general Have very big phase noise.

By taking downlink data transmits as an example, in order to eliminate the phase noise of wireless signal, the antenna mould to terminal device is needed Block carries out phase noise estimation.Phase noise estimation is usually carried out to the Anneta module by PTRS.In addition, in order to transmission nothing The channel of line signal is estimated that access network equipment would generally carry DMRS in wireless signal.It generally accesses in net equipment DMRS port is corresponding with the port PTRS, to realize that PTRS carries out phase for receiving the Anneta module of DMRS in terminal device Noise estimation.I.e. the port PTRS needs and DMRS port combination competence exertion acts on.But under normal circumstances, PTRS port number and DMRS port number is not identical.

So-called port refers to antenna port, expression be the Anneta module for sending or receiving signal port, the application Involved in Anneta module be construed as a kind of logical antenna unit, it includes at least one physical antenna elements, each Physical antenna elements include the devices such as crystal oscillator, i.e., in practical applications, a port can correspond to a physical antenna elements, It may correspond to the aerial array of multiple physical antenna elements compositions.The above-mentioned port PTRS refers to the antenna for sending PTRS Port.DMRS port refers to the antenna port for sending DMRS.

Since in most circumstances, phase noise is all since the crystal oscillator of terminal device or access network equipment generates Caused by the imperfect bring phase Random-Rotation of carrier signal waveform, therefore PTRS port number by terminal device and will also connect The crystal oscillator quantity of the independence (uncorrelated each other) of log equipment determines.In downlink data transmission, access network equipment sends letter Number, terminal device receives signal.Since terminal device is restricted by cost and volume, the crystal oscillator parameter specification that uses compared with Difference is also easier to generate phase noise；And in contrast, the cost and volume of access network equipment be not restricted in a certain range About, therefore used crystal oscillator is with a higher standard, and the phase Random-Rotation deviation of generation is smaller, and the influence to channel estimation is smaller. It therefore is the Anneta module bring phase noise of compensation terminal device, PTRS port number will be equal to terminal under normal circumstances The quantity of independent crystal oscillator in equipment.In 5G communication system, generally at most setting 2 or 4 is independent for most of terminal devices Aerial array corresponds to if the radio-frequency module of each aerial array is to generate carrier signal with an independent crystal oscillator The PTRS port numbers of needs be also 2 or 4.The quantity of DMRS port depends on the number of data streams for needing to transmit. In MIMO transmission mode.Access network equipment can send multiple data flows to terminal device simultaneously, and each data flow is corresponding extremely A few DMRS port.The quantity of usual DMRS port is greater than the quantity of the port PTRS.Do not have accordingly, it is possible to there can be DMRS port There is the problem of corresponding port PTRS.

In order to solve this technical problem, the prior art provides technical solution as shown in Figure 1,2 He of DMRS port DMRS port 3 is known as a DMRS port group, their space QCL each other.It will also be appreciated that the port PTRS 0 and DMRS port 1 is corresponding；The port PTRS 1 is it is also assumed that corresponding with DMRS port 2.In face of space, QCL is described in detail, and Fig. 2 is existing skill The schematic diagram for a kind of polarization multiplexing that art provides, as shown in Fig. 2, two data streams can use pole in multi-layer data transmission The mode for changing multiplexing carries out spatial reuse.Polarization multiplexing refers to that two data streams experienced identical space transmission channel, but its In the antenna element of a data flow be horizontal polarization, the antenna element of another data flow is vertical polarization.Because signal is inclined Vibration is different, orthogonal although the space transmission channel of two data streams is identical, does not interfere with each other.To this transmission space The identical data flow of transmission channel, the multiple DMRS ports used may be considered space QCL's.Data flow 1 in figure as above With data flow 2, corresponding two DMRS ports, the two DMRS ports are known as space QCL, the two DMRS Port constitutes a DMRS port group.

But may exist in the prior art the port PTRS quantity be less than DMRS port group quantity the case where.Such as If access network equipment scheduled 8 layers of most downlink data transmission of Single User MIMO, access network equipment can send 4 waves Beam, each wave beam send two data streams using polarization multiplexing mode, i.e. access network equipment is configured with 4 DMRS port groups altogether Send the DMRS of 8 ports.If terminal device is only configured with two ports PTRS.So certainly exist two DMRS port groups There is no the corresponding port PTRS, be based on this, it would be possible to phase can not be carried out to the corresponding Anneta module of the two DMRS port groups Noise estimation, to reduce the reliability of data transmission.

In order to solve this technical problem, the application provides a kind of phase noise estimation method and equipment.Specifically, Fig. 3 For application scenarios schematic diagram provided by the present application, as shown in figure 3, access network equipment involved in the application can be global movement Communicate (Global System of Mobile communication, abbreviation GSM) or CDMA (Code Division MultipleAccess, abbreviation CDMA) in base station (Base Transceiver Station, abbreviation BTS) in, be also possible to In wideband code division multiple access (Wideband Code Division Multiple Access, abbreviation WCDMA) base station (NodeB, Abbreviation NB), it can also be evolved base station (evolved NodeB, abbreviation eNB) in LTE network, access point (access Point, AP) perhaps relay station be also possible to the base station etc. in 5G network or NR, be not limited thereto.In addition, in the application The terminal device being related to can be directed to user and provide the equipment of voice and/or data connectivity, with wireless connecting function Handheld device or the other processing equipments for being connected to radio modem.

The terminal device can be through wireless access network (Radio Access Network, RAN) and at least one core net It is communicated.The terminal device can be mobile terminal, such as mobile phone (or being " honeycomb " phone) and with mobile terminal Computer, for example, it may be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they Voice and/or data are exchanged with wireless access network.Terminal device is referred to as subscriber unit (Subscriber Unit), uses Family station (Subscriber Station), movement station (Mobile Station), mobile station (Mobile Station), distant station (RemoteStation), access point (Access Point), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent) or user equipment (User Equipment), it is not limited thereto.

Wherein, can be carried out data transmission using MIMO technology between access network equipment and terminal device.

Specifically, Fig. 4 is the flow chart for the phase noise estimation method that one embodiment of the application provides, as shown in figure 4, should Method includes:

Step S401: terminal device determines that M DMRS port group and N number of port PTRS are first corresponding in multiple periods Relationship；

Wherein, M is the positive integer greater than 1, and N is the positive integer more than or equal to 1, and M is greater than N, the DMRS port Group includes at least one DMRS port, and the first corresponding relationship is for making the port PTRS at most correspond to a DMRS over any time period Port set, and the same port PTRS is different in the corresponding DMRS port group of different time sections.

Step S402: terminal device reception access network equipment is sent on multiple periods more by N number of port PTRS A PTRS；

Step S403: terminal device is according to the Anneta module of the first corresponding relationship, M DMRS port group and terminal device Second corresponding relationship determines the corresponding Anneta module of PTRS received on each period；Wherein, Anneta module is for receiving DMRS；

Step S404: terminal device carries out phase noise estimation to the corresponding Anneta module of the PTRS received.

Step S401 is described in detail below, each DMRS port in M DMRS port group is access network equipment For sending the antenna port of DMRS.It wherein, can be by the two ends DMRS if two DMRS ports are space QCL Mouth includes into a DMRS port group.Certainly, the application is not excluded for other port set division modes.In N number of port PTRS Each port PTRS be that access network equipment is used to send the antenna port of PTRS.
