Through this design, in the 5G system, the channel large-scale characteristic parameters representing the spatial information are added by the alignment co-location feature, and this kind of spatial information is compared with other existing quasi-co-location parameters (such as the extension in the existing LTE system). Time-expansion, Doppler spread, Doppler shift, average channel gain, and average delay are used to decouple the groupings to form a parameter set with no overlapping QCL types.

The functions can be distinguished by the configuration information of the reference signals. The configuration parameter associated with the quasi co-location type may include reference signal indication information, and the reference signal configuration information associated with the reference signal may represent a function of the reference signal. For example, the configuration information may include configuration information reported by the UE, and the configuration information reported by the measurement may include information content, format, and the like of the measurement report.

The format refers to the format of the reported content, such as the time-frequency resource indication, the period indication, the coding indication, the scrambling indication, the power indication, and the like. The distinguishing of the function by the configuration information of the reference signal may mean that the function of the reference signal can be distinguished according to the reported configuration information associated with the reference signal. For example, when the reference signal is configured to report the RSRP, the reference signal is a signal for beam management; when the reference signal is configured with a CSI information reporting indication, the reference signal is used to obtain signal quality. Alternatively, the reference signal can be distinguished based on other configuration information associated with the reference signal. For example, when the period configured according to the reference signal, the time-frequency resource density, and the like, it can be known that the reference signal is a reference signal for functions such as frequency offset/timing estimation, channel estimation, and the like.

It should be noted that some of the English abbreviations in this document are described by using the LTE system as an example, which may be related to the network. The evolution changes, and the terminology or expression with similar functions may change. For specific evolution, refer to the description in the corresponding standard.

In the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning.

The terminal device referred to in the present application may include various handheld devices having wireless communication functions, in-vehicle devices, wearable devices, computing devices, control devices, or other processing devices connected to the wireless modem, and defined in existing communication protocols. Various types of user equipment (User Equipment, UE for short), mobile station (MS), terminal (Terminal) or terminal equipment (Terminal Equipment), may also be wireless communication fixed communication devices, etc., as long as Similar wireless communication functions are available, and their names are not limited. For convenience of description, in the present application, the above mentioned devices may be collectively referred to as terminal devices.

The radio access network device involved in the present application may be a transmission point, a base station (BS), a network controller, or a mobile switching center. The device that directly communicates with the user equipment through the wireless channel is usually a base station. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, or Radio Radio Units (RRUs), etc., of course, wireless communication with the user equipment may also be other wireless communication functions. The network side device is not limited to this application. In different systems, the name of a device with base station function may be different. For example, in an LTE network, it may be called an evolved NodeB (eNB or eNodeB). In the third generation (the 3rd Generation, 3G) In the network, it can be called Node B. In the next generation communication system, such as 5G system, the base station is also called gNB.

The quasi-co-location (QCL) concept referred to in the present application generally considers that when the channel large-scale characteristic parameter of the second antenna port can be derived from the channel large-scale characteristic parameter of the first antenna port, Called these two antenna ports quasi co-location. When the quasi-co-location relationship is satisfied, the channel large-scale characteristic parameter between the two antenna ports is the same, and the channel large-scale characteristic parameter includes one of delay spread, Doppler spread, Doppler shift, average gain, and average delay. A variety. After obtaining the quasi co-location assumption, the terminal device can use the information of the known reference signal to compensate the reference signal to be processed, thereby improving the performance of equivalent channel measurement, data demodulation, etc., for example, the terminal device obtains quasi-co-location configuration information. After that, some channel information obtained from a Channel State Information-Reference Signal (CSI-RS) may be used to compensate for Demodulation Reference Signal (DMRS) processing and downlink shared physical channel ( Physical Downlink Shared Channel, referred to as PDSCH) demodulation. Since CoMP can dynamically switch TRP, the quasi co-located relationship between DMRS and CSI-RS can improve the equivalent channel estimation performance of the UE based on DMRS, thereby improving UE receiving performance.

In the LTE protocol version, the large-scale information indicated by the quasi co-location includes: "delay spread, Doppler spread, Doppler shift, average gain, and average delay". That is, delay spread, Doppler spread, Doppler shift, average channel gain, and average delay. The UE assumes the QCL relationship of the large-scale characteristics corresponding to the antenna port according to the QCL behavior and the indication information configured by the network side device. Two types of QCL configurations are defined for the transmission mode (Transmission Mode, TM: 10): Type A (Type-A) and Type B (Type-B), whether Type-A or Type-B is applied, High-level signaling qcl-Operation to configure.

For Type-A, all Cell-specific Reference Signals (CRSs), DMRSs, and CSI-RS antenna ports are considered to satisfy the QCL relationship. For Type-B, the network-side base station first passes RRC signaling. qcl-CSI-RS-ConfigNZPId-r11, configured with an indication of up to four NZP CSI-RS IDs, and then the base station uses physical layer signaling to control the information format 2D (Downlink Control Information Format 2D, referred to as DCIformat2D) The PDSCH RE Mapping and Quasi-Co-Location Indicator (PQI) indicated by the two bits indicates which set of QCL parameters the terminal should use, as shown in Table 1:

Table 1:

As shown in Table 1, the values of the PDSCH RE mapping and the quasi-co-location indication may be four, which are used to indicate which set of configuration parameters are specifically applied by the terminal, as defined in Table 1, when PDSCH RE mapping and quasi-co-location When the value of the two bits is '00', it is used to indicate that the terminal applies the first group of configuration parameters; when the two bits of the PDSCH RE mapping and the quasi-co-location indication are '01', it is used to indicate that the terminal applies the second Group configuration parameter; when the two bits of the PDSCH RE mapping and the quasi-co-location indication are '10', it is used to indicate that the terminal applies the third group configuration parameter; when the PDSCH RE mapping and the quasi-co-location indication are two values '11' is used to instruct the terminal to apply the fourth set of configuration parameters.

For each group of high-level configuration parameters, here take the RRC signaling parameters as an example. Each group of parameters involved in QCL includes:

- crs-PortsCount-r11.

- qcl-CSI-RS-ConfigNZPId-r11.

Where crs-PortsCount-r11. refers to the port number of the CRS, and qcl-CSI-RS-ConfigNZPId-r11. refers to the NZP CSI-RS resource number indicated by the QCL, that is, the non-zero power CSI- The RS resouce number can be used to inform the UE which non-zero power CSI-RS is currently co-located with the DMRS.

After the UE obtains the quasi co-located information, the DMRS processing and the PDSCH demodulation can be compensated by some channel information obtained from the CSI-RS. Since the COMP can dynamically switch the TP, the quasi co-located relationship between the DMRS and the CSI-RS can improve the equivalent channel estimation performance of the UE based on the DMRS, thereby improving the UE receiving performance.

However, the LTE downlink transmission mode technology has the following disadvantages: 1. The scheme considers that all DMRS ports in the same TRP are QCL, but in the 5G NR, the same TRP may have different antenna panels and belong within the same TPR. The DMRS ports of different antenna panels may be non-QCL. In this way, when the cooperation between the different panels is performed, the QCL configuration of the Type-A and Type-B does not solve the problem, which may result in performance loss and cannot support a more flexible transmission mode. 2. The method currently indicated by the PQI is insufficient. Flexible, if you want to support more TRP cooperation in 5G NR, it will lead to more complex PQI indication and increase signaling overhead. The current solution is not easy to extend to NR.

In view of this, FIG. 2 shows a schematic flowchart of a wireless communication data transmission method 200 according to an embodiment of the present application, which is described from the perspective of device interaction. The method 200 can be used in a communication system for communicating over a wireless air interface, which can include a wireless access network device and a terminal device. For example, the communication system can be a similar wireless communication system 100 as shown in FIG.

In the following, without loss of generality, the method 200 is described in detail by taking the interaction between the radio access network device and the terminal device as an example.

As shown, the method includes the following steps:

Step 201: The radio access network device sends the first signaling to the terminal device, where the first signaling includes a first quasi co-location type, and the first quasi co-location type is associated with at least one set of configuration parameters, the first signaling Also including the first quasi co-location type Associated with the at least one set of configuration parameters; the first quasi-co-location type is one of at least two quasi-co-location types preset, and each of the preset quasi-co-location types is quasi-co-shared Each of the address types is associated with at least one channel large-scale characteristic parameter; the first quasi-co-location type is associated with the first-type channel large-scale characteristic parameter, and the first-type channel large-scale characteristic parameter includes at least one channel large-scale characteristic parameter; The radio access network device passes the first signaling, so that the first group of configuration parameters of the at least one set of configuration parameters associated with the first quasi co-location type are applied by the terminal device, thereby facilitating the At least two antenna ports of the quasi co-location are known by the terminal device in the case of at least one channel large-scale characteristic parameter associated with the first quasi-co-location type.

Optionally, in a possible implementation manner, the channel large-scale characteristic parameter may be classified according to a preset rule, and different types of channel large-scale characteristic parameters respectively correspond to different quasi-co-location types, and different quasi-co-location types The associated channel large-scale characteristic parameters may or may not overlap.

As shown in FIG. 3, the QCL type formation and configuration method 300, in the method example, defines 1, 2, 3, ..., K QCL types (K can be a positive integer greater than or equal to 1), each QCL Types are associated with at least one parameter, such as QCL type 1, associated with at least <parameter 1>, <parameter 2>, <parameter 3>, <parameter 4>, ... and other parameters, and for QCL type 1 also configured multiple sets of configuration parameters, such as configuration 1, configuration 2, ... and so on. And so on.

In a possible design, optionally, each QCL type configuration signaling includes at least the following information: information indicating an antenna port, and whether to assume information of the QCL. The configuration expresses whether the antenna port corresponds to a large-scale characteristic of the QCL group in which the configuration is located is QCL.

In a possible design, optionally, the large-scale characteristic parameters of the QCL are grouped according to the function of the reference signal, and the parameters between the groups overlap, as shown in Table 2 below:

Table 2:

As shown in Table 2, the channel large-scale characteristic parameters of the QCL are divided into five QCL groups with parameter overlap, which are called QCL types 1-5. Based on the above idea, in this possible design, the grouping of large-scale characteristic parameters of the channel can be further subdivided or expanded into more QCL types according to the function and characteristics of the port, or group combination is performed, resulting in lower complexity. The QCL type indication.

As shown in Table 2,

For QCL Type 1, a reference signal port (Bam management RS, referred to as BRS) for beam management can be configured. The BRS can be a standalone RS or reuse other RSs. One type or multiple configuration information may be configured in Type 1, for example, "Configuration 1" includes multiple BRS ports, indicating that the large-scale characteristic indicating the beam arrival angle or other characterizing beam space information of these BRS ports is QCL. The BRS port included in this configuration may be a BRS port used in whole or in part.

In a feasible design, the reference signal for beam management multiplexes other RSs, and other RSs that are multiplexed may be a CSI-RS, a synchronization signal (SS), and a synchronization signal of a specific configuration. Any one or any of the units.

The configuration information includes information about at least one signal, and the signal may be any one or any of the following: a cell reference signal, a non-zero power CSI-RS, a zero-power CSI-RS, and a synchronization signal SS (Synchronization) Signal), DMRS in PDSCH, DMRS in PBCH (physical broadcasting channel), zero-power DMRS, channel reference signal SRS, random access channel PRACH, DMRS in PUSCH, DMRS in PUCCH And a tracking reference signal (tracking RS) for time, and/or frequency domain synchronization tracking.

Correspondingly, the signal may be indicated by an antenna port number of the indication signal, an antenna port number, a pilot pattern, a pilot sequence, a time domain resource location, a frequency domain resource location, a resource identifier, a precoding identifier, and the like. Where the time domain resources The source location may be a frame, a subframe, a slot, a minislot, an OFDM symbol, or the like.

Optionally, one or more configuration information configurable in Type 1 may be a QCL relationship between a set of antenna ports regarding spatial information parameters.

For the manner of configuring one or more configuration information in the type 1, the base station may perform the configuration by using any one of an RRC message, a MAC layer cell, and downlink control information, and send the configuration information to the terminal device.

Specifically, the method for configuring by using an RRC message may adopt any one of the following methods:

In one method, the base station carries the following information in the RRC message to the terminal:

QCL cell

The identifier of the CSI-RS signal, such as the resource ID of the CSI-RS

The identifier of the synchronization signal, such as the time domain identifier of the resource where the SS is located.

Signal identifier of the DMRS, such as the identifier of the antenna port (group) of the DMRS

The identifier of the SRS signal, such as the resource identifier of the SRS

As described above, the RRC message carries the cell QCL information, in which the base station indicates a plurality of signals to the UE, such as the CSI-RS, SS, DMRS, and SRS, for indicating the indication indicated by the UE. The antenna ports corresponding to these signals satisfy the QCL relationship of the large-scale parameter space information of type 1 both.

In another method, the base station performs the following level configuration in the RRC message:

CSI-RS configuration domain

SS signal identification

with,

DMRS configuration domain

Identification of CSI-RS signals

The meaning of the method is that the base station configures the QCL relationship between multiple signal pairs. For example, the CSI-RS and the synchronization signal SS are one signal pair, and the CSI-RS and the DMRS are another signal pair. The QCL relationship between the pair of signals can indicate the QCL relationship between the two signals by configuring information of the other signal in one of the signals. By receiving the configuration, the UE can learn the QCL relationship between the SS block and the CSI-RS, the QCL relationship between the CSI-RS and the DMRS, and the like.

Optionally, the base station may configure multiple sets of configurations for the UE in the RRC message, where each group configuration includes a QCL relationship between the multiple signals, and the specific configuration may be implemented by one of the foregoing two methods. The base station activates or triggers one or more sets of configuration information in the MAC cell and or the downlink control information. If the base station uses the above two methods, multiple sets of configuration information are configured in the RRC message, and each group of information includes a QCL relationship between multiple signals:

Configuration 1: CSI-RS resource1, SS block time index 1, DMRS port group1

Configuration 2: CSI-RS resource2, SS block time index 2, DMRS port group2

Configuration 3: CSI-RS resource3, SS block time index 3, DMRS port group3

Configuration 4: CSI-RS resource4, SS block time index 3, DMRS port group4

The CSI-RS resource 1 to 4, the SS block time index 1 to 4, and the DMRS port group 1 to 4 are signal identifiers of the CSI-RS, the SS, and the DMRS, respectively, except for the resource identifier, the time domain identifier, and the antenna port. In addition to the group identification, it may be replaced by other identifiers as described above.

The base station indicates one of the configurations in the DCI, such as one of the configurations 1 to 4 indicated in the DCI. Or the base station indicates multiple sets of configurations in the DCI, such as two of the configurations 1 to 4 indicated in the DCI. For example, if the base station indicates that configuration 1 and configuration 2 are effective, the UE obtains a QCL relationship between the DMRS antenna port in the DMRS port group 1 and the CSI-RS antenna port of the CSI-RS resource 1 and the SS signal in the SS block time index 1 , and the DMRS The DMRS antenna port in port group2 has a QCL relationship with the CSI-RS antenna port of CSI-RS resource 2 and the SS signal in SS block time index 2.

The base station obtains a QCL relationship between the plurality of sets of signals regarding the spatial information by using at least one of an RRC message, a MAC cell, and downlink control information.

For QCL Type 2, one or more Type 2 configurations can be configured. For example: set 2 configurations for type 2, among them, Configuration 1 is that all antenna ports used for phase noise estimation are QCL; configuration 2 is non-QCL for all antenna ports used for phase noise.

When the base station indicates that the UE uses configuration 1 in type 2, the UE needs to assume that all phase noise estimation information on the antenna port for phase noise estimation is consistent, and the phase noise information estimated by the UE on one antenna port may be Push to other antenna ports, that is, use one antenna port for phase noise estimation. When the base station indicates that the UE uses configuration 2 in type 2, the UE cannot assume that the antenna port used for phase noise estimation is QCL, so the phase noise result estimated by the UE in one antenna port is not available to other antenna ports. In this case, when the phase noise is severe, the base station configures the configuration 2 corresponding to the QCL type 2, and the UE performs phase noise estimation on each antenna port.

Similarly, one or more corresponding configuration information is configured in QCL types 3 to 5. Each configuration corresponds to an RS type and a port number indicating the large-scale characteristic to the UE, and the UE is informed of the QCL relationship of the large-scale information in the QCL type corresponding to the ports.

In a possible design, optionally, for one of the pre-set at least two quasi co-location types, if the radio access network device and the terminal device have been defined on both sides in advance A quasi-co-location type indicates a certain parameter configuration, and the terminal can directly pass the quasi-co-location type delivered by the system signaling, such as the name of the quasi-co-location type, or the index, or the ID, and the terminal can Knowing the current QCL configuration, the terminal directly takes effect on the QCL configuration, or the configuration takes effect according to the system effective time indication; of course, the quasi-co-location type information sent by the system signaling can also be carried by the terminal to determine the configuration effective time. Instructions.

Step 202: After the radio access network device sends the first signaling to the terminal device, the radio access network device further sends a second signaling to the terminal device, as shown in FIG. The second signaling includes a second quasi co-location type, the second quasi co-location type is associated with at least one set of configuration parameters, and the second signaling further includes the second quasi co-location type associated with the At least one set of configuration parameters; the second quasi co-location type is one of the preset at least two quasi co-location types; the second quasi co-location type is associated with a second type channel large scale characteristic parameter, The second type channel large-scale characteristic parameter includes at least one channel large-scale characteristic parameter; the radio access network device uses the first signaling and the second signaling to facilitate the first group of configuration parameters And the second set of configuration parameters of the at least one set of configuration parameters associated with the second quasi co-location type are all applied by the terminal device, so that the first type of channel large-scale characteristic parameter is Co-located at least two antenna ports to And at least two antenna ports of the quasi-co-located in the case of the second-class channel large-scale characteristic parameter are known by the terminal device.

The design divides the large-scale characteristic parameters of the channel into different categories according to functions, corresponding to different quasi-co-location types, and configures multiple sets of configuration parameters for each quasi-co-location type, and configures at least two quasi-co-location types. The configuration parameter informs the terminal device by signaling, so that the terminal device can learn at least two quasi-co-located antenna ports corresponding to large-scale characteristic parameters of different types of channels, thereby making the configuration of the quasi-co-location in the communication system more suitable for the 5G new wireless technology. Cooperative transmission in the middle, with greater flexibility.

In a possible design, optionally, since at least two quasi co-location types involve more configuration parameters, the signaling overhead is large for the system, and the physical layer bearer may cause the system to be burdened too much, and the system The configuration information may not need to be valid in real time, so at least one of the first signaling and the second signaling may be implemented by using high layer signaling.

Of course, in the case that a relatively fast configuration is required, the QCL configuration information may be sent to the terminal by using physical layer signaling.

In a possible design, after the radio access network device sends the first signaling to the terminal device, the access network device sends the first indication information to the terminal device, The first indication information is used to instruct the terminal device to apply the first group configuration parameter from the first quasi co-location type associated with at least one set of configuration parameters. In this way, the network side indicates that the terminal device can select and apply a set of suitable configuration parameters from the plurality of sets of configuration parameters associated with the first quasi co-location type.

In a possible design, after the radio access network device sends the second signaling to the terminal device, the access network device sends the second indication information to the terminal device, The second indication information is used to instruct the terminal device to apply the second group configuration parameter from the at least one set of configuration parameters associated with the second quasi co-location type. This As such, the network side indicates that the terminal device can select and apply a set of suitable configuration parameters from among a plurality of sets of configuration parameters associated with the second quasi co-location type.

For example, as shown in FIG. 4, FIG. 4 illustrates a plurality of configuration indication methods 400 based on multiple sets of QCL types, according to which the base stations can combine or independently on the same or different time-frequency resources. The UE indicates each group of QCL parameters. For example, as shown in FIG. 4, an example of a time-division independent indication indicates that the base station indicates the UE at a certain moment. For QCL type 1, configuration 1 is used, and then, at the following moments, respectively, for QCL type 2, Use configuration 2, for QCL type 3, instruct the UE to use configuration 1, and so on.

In a possible design, the foregoing indication information, such as the first indication information and the second indication information, may be carried in the physical layer signaling by the radio access network device to the terminal device, for example, the first The indication information and the second indication information may be sent to the terminal device in the downlink control information (Downlink Control Information, DC for short) in the LTE system, and the physical layer signaling may be used to dynamically notify the terminal device that the current use. Specific configuration to improve system efficiency.

In a possible design, the first indication information and the second indication information may also be carried in the higher layer signaling by the radio access network device to the terminal device, for example, by The bearer is transmitted to the terminal device in a Radio Resource Control (RRC) similar to the LTE system.

For example, the RRC cell QuasiCoLocationIndication carries the indication information to the terminal device, where the name of the cell is not limited. The presentation and presence of the cell may be optional or mandatory. If it is optional, it is recorded as OPTIONAL in the syntax of the cell QuasiCoLocationIndication. When the cell QuasiCoLocationIndication is optional, the cell QuasiCoLocationIndication has an optional read mode tag, which may be --COND, indicating that the cell is read after satisfying certain conditions; or, the tag may be - -Need OP, indicating that the cell is optional. If the cell QuasiCoLocationIndication is missing, does not exist, then the UE does not act; or the tag can be, -Need ON, then when the cell QuasiCoLocationIndication is missing, no When present, the UE uses the currently existing configuration to determine the behavioral hypothesis of the QCL; or, the label can be --Need OR, then when the cell QuasiCoLocationIndication is missing and does not exist, the UE will no longer use the currently existing QCL hypothesis. Configuration, in this case, a possible implementation is the assumption that the UE follows the predefined QCL hypothesis as the large-scale characteristic of the channel between the antenna ports, as assumed, except for the agreement, which is not indicated by the cell. The large-scale characteristics of the channels between antenna ports are not mutually inferrable, that is, non-QCL.

Several alternative behaviors of this cell are hereby possible as possible implementations. The following describes several possible indications of the cell QuasiCoLocationIndication, and the optional behavior of the cell is not marked here.

The first:

QuasiCoLocationIndication::= INTEGER(1..X)

Corresponding to Table 2, X can be 5, corresponding to Table 3, X can be 2, corresponding to Table 4, and X can be 6. The meaning of this cell bearer is that, as shown in the table, the QCL parameter set indicates a specific one of the QCL parameter sets used. For the large-scale characteristic parameter group 1 to group X, when the parameter of the configured cell is a number in 1, 2, .., X, it indicates that the cell is the corresponding QCL parameter group indicated, for example, the number 1 indicates QCL. Parameter group 1, number 2 represents QCL parameter group 2, and so on. Here, the value range of the cell is not limited, and may be a possible implementation such as INTEGER (1..X) or INTEGER (0..X-1). Here, the one-to-one correspondence between the range and the QCL parameter group is not limited in order.

Second:

QuasiCoLocationIndication::= ENUMERATED(q1,q2,q3..,qX)

The meaning of this cell bearer is that, as shown in the table, the QCL parameter set indicates a specific one of the QCL parameter sets used. Here, the one-to-one correspondence between the range and the QCL parameter group is not limited in order.

For the corresponding table 3, the value range of the cell is ENUMERATED (q1, q2). When the domain of the cell is q1, it represents the QCL behavior hypothesis of the large-scale characteristic of the spatial information corresponding to the QCL configuration information; when the domain of the cell is q2, the average channel gain, Doppler shift, corresponding to the QCL configuration information, QCL behavioral assumptions for large-scale characteristics of Doppler spread, average delay, and delay spread.

Or, if corresponding to Table 4, if the value range of the cell is ENUMERATED (q1, q2, q3, q4, q5, q6), when the domain of the cell is q1 or q2 or q3 or q4 or q5 or q6, respectively Indicates the spatial information corresponding to the QCL configuration information, or the average channel gain, Or Qpol behavioral assumptions of Doppler shift, or Doppler spread, or average delay, or large-scale characteristics of delay spread.

Or, as shown in Table 2 above, the channel large-scale characteristic parameters of the QCL can be further subdivided or expanded into more QCL types, or group combining. For example, group 1 is a large-scale parameter of spatial characteristics, group 2 is a large-scale parameter of channel gain, and group 3 is a large-scale parameter of spatial characteristics, Doppler shift, Doppler spread, average delay, and delay spread. Group 4 is a large-scale parameter of Doppler shift, Doppler spread, average delay, and delay spread. This is the cell QuasiCoLocationIndication configurable as q1, q2, q3, q4, corresponding to the four sets of parameters here.

Or, as shown in Table 2 above, the channel large-scale characteristic parameters of the QCL can be further subdivided or expanded into more QCL types, or group combining. For example, group 1 is a large-scale parameter of spatial characteristics, group 2 is a large-scale parameter of channel gain, and group 3 is a large-scale parameter of Doppler shift, Doppler spread, average delay, and delay spread. This is the cell QuasiCoLocationIndication configurable as q1, q2, q3, corresponding to the three sets of parameters here.

The third type:

QuasiCoLocationIndication::= SEQUENCE(SIZE(1..X))OF QuasiCoLocationBehavior

It means that the cell QuasiCoLocationIndication is composed of multiple sets of configurations, and a total of X group parameter configurations are combined into one sequence. One of the configurations corresponds to the QCL behavior hypothesis configuration between the antenna ports of a set of QCL parameters.

Fourth:

QuasiCoLocationIndication::= BOOLEAN

For example, when corresponding to Table 3, when there are only two sets of parameters, a single bit can be used to indicate the QCL parameter set corresponding to the configured configuration parameter. If the bit is 0, it indicates the channel large-scale parameter in the group 1 corresponding to the configuration parameter, or the bit is 0, indicating the channel large-scale parameter in the group 2 corresponding to the configuration parameter.

Alternatively, when corresponding to Table 3, the cell can be interpreted as a large-scale parameter group containing spatial parameters, which is referred to herein as Group 1 in Table 2. When the cell is configured to be 0, it indicates that there is no large-scale parameter configuration between the antenna ports regarding the spatial information parameters, otherwise, it indicates that there is a large-scale parameter configuration between the antenna ports regarding the spatial information parameters.

Alternatively, as shown in Table 2 above, the channel large-scale characteristic parameters of the QCL may be further subdivided or expanded into more QCL types, or group combining. The value of the cell may indicate whether at least one large-scale parameter group containing spatial parameters is configured.

The fifth one:

QuasiCoLocationIndication::= BIT STRING(SIZE(X))

The value range of the cell is in the form of a bit table forming a bit stream. Each bit in the bit stream configured by the cell QuasiCoLocationIndication corresponds to whether the parameter of the corresponding large-scale parameter group is configured.

As shown in Table 3, the bit stream is two bits. The configuration 1/0 of the first bit corresponds to whether the QCL behavior between the antenna ports corresponds to the large-scale parameter of the spatial information, and the configuration 1/0 of the second bit corresponds to whether the QCL behavior between the antenna ports corresponds to the average channel gain. Large-scale parameters of Doppler shift, Doppler spread, average delay, and delay spread.

Or, as corresponding to Table 4, the bit stream is 6 bits. The 1/0 configuration of the 1st to 6th bit positions respectively indicates whether the QCL behavior between the antenna ports corresponds to spatial information, or average channel gain, or Doppler shift, or Doppler spread, or average delay. , or large-scale features of delay spread.

In a possible design, the first set of configuration parameters is used to carry the first effective time indication information, where the first effective time indication information is used to indicate the first group of the terminal device. Setting the effective time of the parameter, so that the effective time of at least two antenna port quasi-co-locations is known by the terminal device in the case of the first type of large-scale characteristic parameter; and/or the applied second group configuration The second effective time indication information is carried in the parameter, where the second effective time indication information is used to indicate the effective time of the second set of configuration parameters of the terminal device, so that at least the second type of large-scale characteristic parameter is used. The effective time of the quasi-co-location of the two antenna ports is known by the terminal device.

In a possible design, the effective time is used to indicate a time window in which a set of configuration parameters is valid. Specifically, an active/deavive signaling indication may be used. For example, in a QCL configuration, the current configuration is no longer valid. When deactive signaling is used to cancel its configuration, the signaling overhead of reconfiguring other configuration types is reduced.

In a possible design, the access network device sends the first effective time indication signaling to the terminal device, where the first effective time indication signaling is used to indicate the terminal device The effective time of a set of configuration parameters, so that the effective time of at least two antenna port quasi-co-locations is known by the terminal device in the case of the first type of large-scale characteristic parameters; and/or the access network device sends a second effective time indication signaling is sent to the terminal device, where the second effective time indication signaling is used to indicate an effective time of the second set of configuration parameters of the terminal device, so as to facilitate the second type of large-scale characteristic In the case of a parameter, the effective time of at least two antenna port quasi co-locations is known by the terminal device. In this design, after receiving the QCL configuration information, the UE reads the signaling related to the effective time, and performs QCL hypothesis on the corresponding antenna port according to the configuration in the QCL configuration information in the indicated time period.

In a possible design, the system may define an implicit configuration effective time: the UE assumes that the effective time is one time from the initial indication to the next time the new indication is generated according to the preset rule. Then, once the UE receives a certain configuration information, the corresponding QCL hypothesis is made according to the current configuration information before the next configuration information arrives.

In a possible design, optionally, the UE assumes that the inactive antenna port satisfies the default QCL relationship. For example, all unspecified large-scale characteristics of the antenna port that does not have an effective indication are considered to be non-QCL. The indicated QCL information can be assumed until the UE receives the relevant QCL configuration information.

In a possible design, optionally, the first-type channel large-scale characteristic parameter is a parameter that characterizes a beam space feature, and includes any one or any combination of the following: an Angle of Arival (AoA). , Angle of Arival Apread (AoAS), Angle of Departure (AoD), Angle of departure spread (AoDS), Receive Antenna Spatial Correlation (Receiving Antenna Spatial Correlation) ).

Specifically, a possible design, optionally, a method involving non-overlapping large-scale characteristic parameters between quasi-co-location types as shown in Table 3. The method is extended in the QCL definition in 5G, and the above-mentioned large-scale parameters representing spatial information are added, and this type of spatial information is compared with other existing QCLs (such as channel quality large-scale parameters commonly used in LTE systems: average channel gain, Parameter decoupling of Doppler shift, Doppler spread, average delay, delay spread, etc.).

table 3:

As shown in Table 3, where QCL Type 2 can be the QCL type of existing LTE. The method shown in Table 3 decouples the spatial information from other parameters, indicating the large-scale characteristics of each antenna port.

For example, for QCL type 1, it can be configured for antenna ports for beam management. The antenna ports used for beam management may be separate RS types, or multiplexed with RS types such as DMRS. It is expressed here as BRS. One or more sets of BRS configurations are configured in Type 1, and each configuration may include all or part of the BRS ports.

Through this design, in the 5G system, the channel large-scale characteristic parameters representing the spatial information are added by the alignment co-location feature, and this kind of spatial information is compared with other existing quasi-co-location parameters (such as the extension in the existing LTE system). Time-expansion, Doppler spread, Doppler shift, average channel gain, and average delay are used to decouple the groupings to form a parameter set with no overlapping QCL types.

The configuration information includes information about at least one signal, and the signal may be any one or any of the following: a cell reference signal, a non-zero power CSI-RS, a zero-power CSI-RS, and a synchronization signal SS (Synchronization) Signal), DMRS in PDSCH, DMRS in PBCH (physical broadcasting channel), zero-power DMRS, channel reference signal SRS, random access channel PRACH, DMRS in PUSCH, DMRS in PUCCH And a tracking reference signal (tracking RS) for time, and/or frequency domain synchronization tracking.

Correspondingly, the signal may be indicated by an antenna port number of the indication signal, an antenna port number, a pilot pattern, a pilot sequence, a time domain resource location, a frequency domain resource location, a resource identifier, a precoding identifier, and the like. The time domain resource location may be a frame, a subframe, a time slot, a mini slot, an OFDM symbol, or the like.

Optionally, one or more configuration information configurable in type 1 may be a space between a group of antenna ports. The QCL relationship of the information parameters.

For the manner of configuring one or more configuration information in the type 1, the base station may perform the configuration by using any one of an RRC message, a MAC layer cell, and downlink control information, and send the configuration information to the terminal device.

Specifically, the method for configuring by using an RRC message may adopt any one of the following methods:

In one method, the base station carries the following information in the RRC message to the terminal:

QCL cell

The identifier of the CSI-RS signal, such as the resource ID of the CSI-RS

The identifier of the synchronization signal, such as the time domain identifier of the resource where the SS is located.

Signal identifier of the DMRS, such as the identifier of the antenna port (group) of the DMRS

The identifier of the SRS signal, such as the resource identifier of the SRS

As described above, the RRC message carries the cell QCL information, in which the base station indicates a plurality of signals to the UE, such as the CSI-RS, SS, DMRS, and SRS, for indicating the indication indicated by the UE. The antenna ports corresponding to these signals satisfy the QCL relationship of the large-scale parameter space information of type 1 both.

In another method, the base station performs the following level configuration in the RRC message:

CSI-RS configuration domain

SS signal identification

with,

DMRS configuration domain

Identification of CSI-RS signals

The meaning of the method is that the base station configures the QCL relationship between multiple signal pairs. For example, the CSI-RS and the synchronization signal SS are one signal pair, and the CSI-RS and the DMRS are another signal pair. The QCL relationship between the pair of signals can indicate the QCL relationship between the two signals by configuring information of the other signal in one of the signals. By receiving the configuration, the UE can learn the QCL relationship between the SS block and the CSI-RS, the QCL relationship between the CSI-RS and the DMRS, and the like.

Optionally, the base station may configure multiple sets of configurations for the UE in the RRC message, where each group configuration includes a QCL relationship between the multiple signals, and the specific configuration may be implemented by one of the foregoing two methods. The base station activates or triggers one or more sets of configuration information in the MAC cell and or the downlink control information. If the base station uses the above two methods, multiple sets of configuration information are configured in the RRC message, and each group of information includes a QCL relationship between multiple signals:

Configuration 1: CSI-RS resource1, SS block time index 1, DMRS port group1

Configuration 2: CSI-RS resource2, SS block time index 2, DMRS port group2

Configuration 3: CSI-RS resource3, SS block time index 3, DMRS port group3

Configuration 4: CSI-RS resource4, SS block time index 3, DMRS port group4

The CSI-RS resource 1 to 4, the SS block time index 1 to 4, and the DMRS port group 1 to 4 are signal identifiers of the CSI-RS, the SS, and the DMRS, respectively, except for the resource identifier, the time domain identifier, and the antenna port. In addition to the group identification, it may be replaced by other identifiers as described above.

The base station indicates one of the configurations in the DCI, such as one of the configurations 1 to 4 indicated in the DCI.

The time domain resource location may be a frame, a subframe, a time slot, a mini slot, an OFDM symbol, or the like.

Wherein, for the QCL relationship of type 1 regarding the QCL relationship in the spatial information, the type 3 about the Doppler shift, the Doppler spread, the average delay, and the delay spread, the base station configures a group or a high-level RRC message. QCL configuration for multiple sets of signals.

Optionally, one or more configuration information configurable in Type 1 may be a QCL relationship between a set of antenna ports regarding spatial information parameters.

For the manner of configuring one or more configuration information in the type 1, the base station may perform the configuration by using any one of an RRC message, a MAC layer cell, and downlink control information, and send the configuration information to the terminal device.

Specifically, the method for configuring by using an RRC message may adopt any one of the following methods:

In one method, the base station carries the following information in the RRC message to the terminal:

QCL cell

The identifier of the CSI-RS signal, such as the resource ID of the CSI-RS

The identifier of the synchronization signal, such as the time domain identifier of the resource where the SS is located.

Signal identifier of the DMRS, such as the identifier of the antenna port (group) of the DMRS

The identifier of the SRS signal, such as the resource identifier of the SRS

As described above, the RRC message carries the cell QCL information, in which the base station indicates a plurality of signals to the UE, such as the CSI-RS, SS, DMRS, and SRS, for indicating the indication indicated by the UE. The antenna ports corresponding to these signals satisfy the QCL relationship of the large-scale parameter space information of type 1 both.

In another method, the base station performs the following level configuration in the RRC message:

CSI-RS configuration domain

SS signal identification

with,

DMRS configuration domain

Identification of CSI-RS signals

The meaning of the method is that the base station configures the QCL relationship between multiple signal pairs. For example, the CSI-RS and the synchronization signal SS are one signal pair, and the CSI-RS and the DMRS are another signal pair. The QCL relationship between the pair of signals can indicate the QCL relationship between the two signals by configuring information of the other signal in one of the signals. By receiving the configuration, the UE can learn the QCL relationship between the SS block and the CSI-RS, the QCL relationship between the CSI-RS and the DMRS, and the like.

Optionally, the base station may configure multiple sets of configurations for the UE in the RRC message, where each group configuration includes a QCL relationship between the multiple signals, and the specific configuration may be implemented by one of the foregoing two methods. The base station activates or triggers one or more sets of configuration information in the MAC cell and or the downlink control information. If the base station uses the above two methods, multiple sets of configuration information are configured in the RRC message, and each group of information includes a QCL relationship between multiple signals:

Configuration 1: CSI-RS resource1, SS block time index 1, DMRS port group1

Configuration 2: CSI-RS resource2, SS block time index 2, DMRS port group2

Configuration 3: CSI-RS resource3, SS block time index 3, DMRS port group3

Configuration 4: CSI-RS resource4, SS block time index 3, DMRS port group4

The CSI-RS resource 1 to 4, the SS block time index 1 to 4, and the DMRS port group 1 to 4 are signal identifiers of the CSI-RS, the SS, and the DMRS, respectively, except for the resource identifier, the time domain identifier, and the antenna port. In addition to the group identification, it may be replaced by other identifiers as described above.

The base station indicates one of the configurations in the DCI, such as one of the configurations 1 to 4 indicated in the DCI. Or the base station indicates multiple sets of configurations in the DCI, such as two of the configurations 1 to 4 indicated in the DCI. For example, if the base station indicates that configuration 1 and configuration 2 are effective, the UE obtains a QCL relationship between the DMRS antenna port in the DMRS port group 1 and the CSI-RS antenna port of the CSI-RS resource 1 and the SS signal in the SS block time index 1 , and the DMRS The DMRS antenna port in port group2 has a QCL relationship with the CSI-RS antenna port of CSI-RS resource 2 and the SS signal in SS block time index 2.

The base station obtains a QCL relationship between the plurality of sets of signals regarding the spatial information by using at least one of an RRC message, a MAC cell, and downlink control information.

For Type 2, the QCL relationship between the antenna ports with respect to channel gain, the UE can be determined by a QCL relationship between the predefined antenna ports with respect to channel gain.

For Type 3, the base station can configure one or more sets of signal QCL relationships for the UE. The signals include DMRS, TRS (tracking RS), synchronization signals, and the like. The TRS is a reference signal for the UE to perform time and frequency synchronization, and the TRS may be a separate TRS, or a specific configured CSI-RS.

For example, the base station can configure the following information in the RRC message.

DMRS port group

TRS ID

The configuration indicates that the DMRS port in the configured DMRS port (group) and the TRS in the configured TRS resource have a QCL relationship with respect to Doppler shift, Doppler spread, average delay, and delay spread. . In this way, the UE can perform fine synchronization of time and frequency according to the TRS, and apply the synchronization to the receiving PDSCH.

In the method disclosed above, the base station configures the QCL relationship of the spatial information about one or more sets of signals to the UE, and/or one or more sets of signals about Doppler shift, Doppler spread, and average delay. The QCL relationship of delay extension. Specifically, the base station configures one or more sets of configuration information about the spatial information QCL for the UE, and configures one for the UE about Doppler frequency shift, Doppler spread, average delay, and delay spread QCL. Group or groups of configuration information.

Optionally, the base station may indicate, in the MAC cell, and/or the downlink control information, a QCL relationship between signals used by the UE. Specifically, the base station may respectively indicate that the UE uses one or more sets of configuration letters regarding the QCL relationship of the spatial information. One or more configurations in the interest, and/or one or more of one or more sets of configuration information for the UE using QCL relationships for Doppler shift, Doppler spread, average delay, and delay spread Configuration. Or specifically, the base station may indicate in the same signaling domain that the UE uses one or more configurations of one or more sets of configuration information about the QCL relationship of the spatial information, and/or the UE uses about Doppler One or more of one or more sets of configuration information for frequency shift, Doppler spread, average delay, and delay extended QCL relationships. That is, the indication information is sent by using a signaling domain in the downlink control information, one or more sets of one quasi co-location type that one signaling domain can indicate, or one signaling domain can indicate multiple quasi co-location types. One or more sets of configurations, or multiple signaling domains, are used to indicate one or more sets of configurations of a plurality of quasi co-location types.

Table 6:

Illustratively, Table 6 may employ a configuration in which QCL for Type 1 regarding QCL relationships in spatial information, Type 3 for Doppler shift, Doppler spread, average delay, and delay spread. The QCL relationship in the relationship, type 4, for spatial information, Doppler shift, Doppler spread, average delay, and delay spread, the base station configures the QCL configuration of one or more sets of signals in the high layer RRC message.

The configuration information includes information about at least one signal, and the signal may be any one or any of the following: a cell reference signal, a non-zero power CSI-RS, a zero-power CSI-RS, and a synchronization signal SS (Synchronization) Signal), DMRS in PDSCH, DMRS in PBCH (physical broadcasting channel), zero-power DMRS, channel reference signal SRS, random access channel PRACH, DMRS in PUSCH, DMRS in PUCCH And a tracking reference signal (tracking RS) for time, and/or frequency domain synchronization tracking.

Correspondingly, the signal may be indicated by an antenna port number of the indication signal, an antenna port number, a pilot pattern, a pilot sequence, a time domain resource location, a frequency domain resource location, a resource identifier, a precoding identifier, and the like. The time domain resource location may be a frame, a subframe, a time slot, a mini slot, an OFDM symbol, or the like.

For Type 1, similarly, the configuration method of Type 1 of Table 5 can be employed; for Type 3, similarly, the configuration method of Type 3 of Table 5 can be employed.

For Type 4, the base station can configure one or more sets of configuration information for the UE in the RRC message. The set of configuration information may include a configuration of one or more of the foregoing signals; or a configuration including one or more of the foregoing signals and at least one large-scale parameter of type 4.

In a set of configurations of type 4, if an indication of more than two signals is configured to indicate a QCL relationship for more than two signals, there are two configurations. In one mode, the base station configures indications of more than two signals in the same signaling domain; or, the base station configures two pairs of indications of multiple pairs of signal pairs.

Further, the base station configures one or more sets of configurations of Type 1, Type 3, and Type 4 in the RRC message, and the base station may further indicate one or more of the MAC cells, and/or the downlink control information.

Specifically, the base station may respectively indicate that the UE uses one or more configurations of one or more sets of configuration information regarding a QCL relationship of spatial information, and/or the UE uses about Doppler shift, Doppler spread, One or more of one or more sets of configuration information for an average delay, delay extended QCL relationship, and/or UE usage with respect to spatial information, Doppler shift, Doppler spread, average delay One or more of one or more sets of configuration information for a QCL relationship that is extended by time delay. Or specifically, the base station may indicate in the same signaling domain that the UE uses one or more configurations of one or more sets of configuration information about the QCL relationship of the spatial information, and/or the UE uses about Doppler One or more of one or more sets of configuration information for frequency shift, Doppler spread, average delay, delay extended QCL relationship, and/or UE One or more of one or more sets of configuration information for spatial information, Doppler shift, Doppler spread, average delay, delay spread QCL relationship. That is, the indication information is sent by using a signaling domain in the downlink control information, one or more sets of one quasi co-location type that one signaling domain can indicate, or one signaling domain can indicate multiple quasi co-location types. One or more sets of configurations, or multiple signaling domains, are used to indicate one or more sets of configurations of a plurality of quasi co-location types.

The definition of QCL in this embodiment may refer to the definition in LTE, that is, the signal sent from the antenna port of the QCL will undergo the same large-scale fading, and the large-scale fading includes one or more of the following: delay extension, Doppler Le expansion, Doppler shift, average channel gain, and average delay.
