Description

[0001] This application claims the priority of the Chinese patent application filed with the Intellectual Property Office of the People's Republic of China on September 27, 2023, with application number 202311273544.0 and invention name "A Resource Allocation Method and Device", all contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a resource configuration method and device. Background Art

[0003] With the popularization of the fifth generation (5G) mobile communication devices and the emergence of a large number of new business types such as extended reality (XR) and short videos, the traffic demand has increased significantly. In order to meet the rapidly growing traffic demand, massive multiple-input multiple-output (massive MIMO) technology has evolved to a larger antenna scale, for example, from 32 antenna ports to 64 antenna ports, or even higher.

[0004] At present, the existing channel state information-reference signal (CSI-RS) resources can only support up to 32 antenna ports. Therefore, for the frequency division duplex (FDD) system with a 64-antenna port antenna array, it is impossible to obtain the channel state information of the complete spatial dimension, resulting in a large performance loss. Summary of the invention

[0005] The present application provides a resource configuration method and device for configuring CSI-RS resources that support a larger number of ports.

[0006] In a first aspect, the present application provides a resource configuration method, which can be executed by a network device or a module (such as a chip) in the network device. The method includes: sending first indication information to a terminal device; the first indication information is used to indicate M reference signal resources, among the ports corresponding to the M reference signal resources, the minimum port index is 0+C, the maximum port index is K-1+C, K is the sum of the number of ports corresponding to the M reference signal resources, M is an integer greater than or equal to 2, C is a constant, and K is an integer greater than 32; sending reference signals on the M reference signal resources and receiving CSI from the terminal device, the CSI is determined according to the reference signal.

[0007] Through the above method, the network device can configure M reference signal resources, and the total number of ports corresponding to these reference signal resources is greater than 32. Since the minimum port index of the ports corresponding to these reference signal resources is 0+C, and the maximum port index is K-1+C, it is possible to uniformly number the port indexes of the ports corresponding to these reference signal resources, rather than individually numbering the port indexes of the ports corresponding to each reference signal resource. This allows the network device to determine that the ports corresponding to the M reference signal resources correspond to the same TRP, and the M reference signal resources can support a larger number of antenna ports, which can be applicable to FDD systems with antenna arrays with more than 32 antenna ports.

[0008] The reference signal resource may be a CSI-RS resource or a demodulation reference signal (DMRS) resource, etc., which is not limited in the present application.

[0009] In one possible design, port indexes of any two reference signal resources among the M reference signal resources are different.

[0010] In one possible design, the port index p corresponding to the reference signal resource with sequence number m is m It is obtained according to the index of the code division multiplexing CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the number of ports corresponding to the reference signal resources with sequence number less than or equal to m, 0≤m≤M-1, m is an integer.

[0011] In one possible design, the p m The corresponding relationship between the index of the CDM group of the reference signal resource with a sequence number of m, the index of the sequence within the CDM group of the reference signal resource with a sequence number of m, the size of the CDM group of the reference signal resource with a sequence number of m, and the number of ports corresponding to the reference signal resource with a sequence number less than or equal to m is:

[0012]

[0013] Wherein, j represents the index of the CDM group, s represents the index of the sequence in the CDM group, 0≤s≤L m -1, N m represents the number of ports of the reference signal resource with sequence number m, L m represents the size of the CDM group, is the sum of the number of ports corresponding to the reference signal resources with sequence numbers less than m, N mis the number of ports corresponding to the reference signal resource with sequence number m, and j and s are integers.

[0014] By adopting the above method, the port indexes corresponding to the M reference signal resources can be determined relatively simply. However, each reference signal resource cannot constitute an independent dual-polarized antenna array, so the reuse of the reference signal resources cannot be achieved.

[0015] In a possible design, the number of ports corresponding to the M reference signal resources is N, K=M*N, and N is a positive integer.

[0016] In one possible design, the port index p corresponding to the reference signal resource with sequence number m is m According to the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m and the value of N, 0≤m≤M-1, m is an integer.

[0017] In one possible design, the p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N is:

[0018] p m =C+s+jL m +mN

[0019] Wherein, j represents the index of the CDM group, s represents the index of the sequence in the CDM group, 0≤s≤L m -1,L m represents the size of the CDM group, j and s are integers.

[0020] By adopting the above method, when the number of ports corresponding to the M reference signal resources is the same, the port indexes corresponding to the M reference signal resources can be determined more easily. Among them, each reference signal resource cannot constitute an independent dual-polarized antenna array, so the reuse of reference signal resources cannot be achieved.

[0021] In one possible design, the p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N is:

[0022] p m =C+(s+jLm )M+m

[0023] Wherein, j represents the index of the CDM group, s represents the index of the sequence in the CDM group, 0≤s≤L m -1,L m represents the size of the CDM group, j and s are integers.

[0024] Therefore, the port corresponding to each reference signal resource can correspond to an array, which is a uniform dual-polarization array, and then the port corresponding to a single reference signal resource can also be used for separate quantization reporting, thereby realizing the reuse of reference signal resources. In other words, each of the M reference signal resources can be used as a separate measurement resource for terminal devices that do not support channel measurement of more than 32 ports. Taking into account that in actual deployment, due to the different measurement capabilities of terminal devices, there are some terminal devices that only support reference signal resources of no more than 32 ports. Therefore, the above method can realize the reuse of reference signal resources and reduce the overhead of reference signal resources. Using the above method, the formula of the port index is simple, easy to implement, and can realize the reuse of reference signal resources.

[0025] In one possible design, the port index p corresponding to the reference signal resource with sequence number m is m The port group corresponding to each reference signal resource is obtained according to the number of ports n1 in the first dimension in one polarization direction, the number of ports n2 in the second dimension in one polarization direction of the port group corresponding to each reference signal resource, and the position of the port group corresponding to the reference signal resource with serial number m in the port groups corresponding to the M reference signal resources respectively.

[0026] In one possible design, the port index p corresponding to the reference signal resource with sequence number m is m It is obtained according to the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, the value of N, the number of ports n1 of the port group corresponding to each reference signal resource in a first dimension in one polarization direction, the number of ports n2 of the port group corresponding to each reference signal resource in a second dimension in one polarization direction, the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, and the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension, wherein 0≤m≤M-1, m is an integer, K=2M*n1*n2, the port groups corresponding to the M reference signal resources respectively have the same number of ports in the first dimension, and the port groups corresponding to the M reference signal resources respectively have the same number of ports in the second dimension.

[0027] In the above manner, each reference signal resource corresponds to a dual-polarization array array, so for a single reference signal resource, the existing codebook can be used for quantization feedback, that is, a single reference signal resource can be used for a separate quantization report, and then the multiplexing of the reference signal resource can be realized. Therefore, each of the M reference signal resources can be used as a separate measurement resource for terminal devices that do not support channel measurement of more than 32 ports. Considering that in actual deployment, due to different measurement capabilities of terminal devices, there are some terminal devices that only support reference signal resources of no more than 32 ports. Therefore, the above manner can realize the multiplexing of reference signal resources and reduce the overhead of reference signal resources.

[0028] In one possible design, the port index p corresponding to the reference signal resource with sequence number m is m Determined by the following formula A or formula B:

[0034] In one possible design, N1=n1 or N2=n2.

[0035] In a possible design, when N1=n1 and / or N2=n2, K, N1, N2, n1 and n2 satisfy one or more of the following corresponding relationships:

[0036] When K=48, N1=8, N2=3, n1=4, n2=3; or, when K=48, N1=8, N2=3, n1=8, n2=1; or, when K=48, N1=6, N2=4, n1=6, n2=2; or, when K=64, N1=16, N2=2, n1=8, n2=2; or, when K=64, N1=16, N2=2, n1=16, n2=1; or, When K=64, N1=8, N2=4, n1=4, n2=4; or, when K=64, N1=8, N2=4, n1=8, n2=2; or, when K=128, N1=16, N2=4, n1=4, n2=4; or, when K=128, N1=16, N2=4, n1=16, n2=1; or, when K=128, N1=8, N2=8, n1=8, n2=2.

[0037] In a possible design, the number of ports corresponding to the M reference signal resources is N, N m =N; and / or the sizes of the CDM groups corresponding to the M reference signal resources are both L, L m =L.

[0038] In a possible design, the M reference signal resources correspond to K ports in total, and the ports included in the port group corresponding to each reference signal resource correspond one-to-one to some of the K ports.

[0039] In one possible design, second indication information is sent to the terminal device, wherein the second indication information indicates the number of ports n1 of the port group corresponding to each reference signal resource in a first dimension in a polarization direction and / or the number of ports n2 of the port group corresponding to each reference signal resource in a second dimension in a polarization direction.

[0040] In a possible design, the serial numbers corresponding to the M reference signal resources are determined according to the identifiers corresponding to the M reference signal resources, or according to the configuration order of the M reference signal resources.

[0041] In one possible design, third indication information is sent to the terminal device, wherein the third indication information indicates the number of ports N1 in a first dimension in a polarization direction and / or the number of ports N2 in a second dimension in a polarization direction, N1 and N2 are positive integers, and K=2N1*N2; the method further includes: determining the ports corresponding to the M reference signal resources and the corresponding port indexes based on the number of ports N1 in the first dimension in one polarization direction, the number of ports N2 in the second dimension in one polarization direction and the polarization direction.

[0043] Through the above method, the terminal device receives the reference signal based on the M reference signal resources configured by the network device. Since the minimum port index among the ports corresponding to these reference signal resources is 0+C, and the maximum port index is K-1+C, the terminal device determines that the ports corresponding to the M reference signal resources correspond to the same TRP. The terminal device performs quantized reporting for the channel of a TRP, and only needs to report one CSI. Compared with the CJT solution, the terminal device needs to feedback M CSIs for quantized reporting for the channels of M TRPs, which can save feedback overhead.

[0156] Figure 1 FIG. 1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The wireless access network 100 may include at least one wireless access network device (such as Figure 1 110a and 110b), and may also include at least one terminal device (such as Figure 1 120a-120j in the figure). The terminal device is connected to the wireless access network device by wireless means, and the wireless access network device is connected to the core network by wireless or wired means. The core network device and the wireless access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated on the same physical device, or part of the functions of the core network device and part of the functions of the wireless access network device can be integrated on one physical device. Terminal devices and terminal devices, as well as wireless access network devices and wireless access network devices can be connected to each other by wired or wireless means. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Figure 1 Not drawn in.

[0157] The wireless access network equipment may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation base station in the sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes part of the functions of a base station, for example, it may be a central unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and may also complete the functions of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and may also complete the functions of part or all of the physical layer. For the specific description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The wireless access network device can be a macro base station (such as Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For ease of description, the following description takes the network device as an example of the wireless access network device.

[0158] Terminal devices may also be referred to as terminals, user equipment (UE), mobile stations, mobile terminals, etc. Terminal devices can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. Terminal devices may be mobile phones, tablet computers, computers with wireless transceiver functions, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal devices.

[0159] The network equipment and terminal equipment can be fixed or movable. The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of the present application do not limit the application scenarios of the network equipment and terminal equipment.

[0160] The roles of network devices and terminal devices can be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile network device. For the terminal devices 120j that access the wireless access network 100 through 120i, the drone 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, network devices and terminal devices can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having network device functions. Figure 1 120a-120j in the figure can be called communication devices with terminal equipment functions.

[0161] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through authorized spectrum, unauthorized spectrum, or both; can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0162] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem including the network device function. The control subsystem including the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device including the terminal device function.

[0163] In an embodiment of the present application, the network device sends a downlink signal or downlink information to the terminal device, and the downlink information is carried on a downlink channel; the terminal device sends an uplink signal or uplink information to the network device, and the uplink information is carried on an uplink channel. In order to communicate with the network device, the terminal device needs to establish a wireless connection with the cell controlled by the network device. The cell with which the terminal device has established a wireless connection is called the service cell of the terminal device. When the terminal device communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0164] It can be understood that in the embodiments of the present application, the physical downlink shared channel (PDSCH), the physical downlink control channel (PDCCH), the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH) are only used as examples of downlink data channels, downlink control channels, uplink control channels and uplink data channels, respectively. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of the present application do not limit this.

[0165] The following is a brief description of the basic concepts involved in this application:

[0166] (1) Reference signal

[0167] In a communication system, a pilot signal may also be referred to as a reference signal (RS), which is a signal known to both the transmitter and the receiver and provided by the transmitter to the receiver for channel estimation or channel detection. Reference signals are divided into uplink reference signals and downlink reference signals. Unless otherwise specified, the reference signal in this application is a downlink reference signal. Exemplarily, the downlink reference signal may be a CSI-RS, or a demodulation reference signal (DMRS), etc., which is not limited in this application. Accordingly, the reference signal resource is a CSI-RS resource or a DMRS resource.

[0168] In the following embodiments, only the reference signal resource is a CSI-RS resource as an example for illustration. Exemplarily, the CSI-RS resource includes at least one of the time-frequency resources, antenna ports, power resources, and scrambling code resources of the CSI-RS. Exemplarily, the network device can send CSI-RS to the terminal based on the CSI-RS resource, and correspondingly, the terminal can receive CSI-RS based on the CSI-RS resource. In the embodiments of the present application, one or more antenna ports corresponding to the CSI-RS resource can also be understood as one or more antenna ports included in the CSI-RS resource.

[0169] (2) Channel state information (CSI)

[0170] In the process of a signal passing through a wireless channel from a transmitter to a receiver, it may experience scattering, reflection, or energy attenuation with distance, thus causing fading. CSI is used to characterize the characteristics of a wireless channel and may include at least one of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a synchronization signal / physical broadcast channel block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI), L1-reference signal received power (RSRP), and L1-signal to interference plus noise ratio (SINR). CSI can be sent by a terminal device to a network device via PUCCH or PUSCH.

[0171] In the embodiments of the present application, if there is no logical conflict, "CSI" or "CSI report (CSI report)" can be interchanged, and "report", "feedback" and "send" can be interchanged.

[0172] (3) CSI configuration

[0173] The current CSI configuration may include a CSI report configuration (CSI-ReportConfig), wherein CSI-ReportConfig includes channel measurement resources (resourcesForChannelMeasurement), which are used to configure CSI-RS resources for channel measurement, and are associated with the CSI resource configuration (CSI-ResourceConfig) through a CSI resource configuration identifier (CSI-ResourceConfigId). For example, resourcesForChannelMeasurement may carry a CSI-ResourceConfigId for channel measurement; CSI-ReportConfig also includes a codebook configuration (codebookConfig).

[0174] CSI-ResourceConfig is used to configure the relevant information of the reference signal resources, such as the time-frequency resources, antenna ports, power resources or scrambling codes of the reference signal. For example, CSI-ResourceConfig may include a CSI resource set list (CSI-RS-ResourceSetList), which is associated with the configuration of the NZP-CSI-RS resource set (NZP-CSI-RS-ResourceSet) through a non-zero power (NZP) CSI-RS resource set identifier (NZP-CSI-RS-ResourceSetId). NZP-CSI-RS-ResourceSet includes a nzp-CSI-RS-Resources field, which is associated with at least one NZP-CSI-RS-Resource through at least one NZP-CSI-RS resource identifier (NZP-CSI-RS-ResourceId).

[0175] codebookConfig: used to configure MIMO codebook related information, such as codebook type, number of ports N1 in the first dimension, and number of ports N2 in the second dimension.

[0176] It should be understood that CSI-ReportConfig, or CSI-ResourceConfig, or codebookConfig may also include other fields, which are not listed here one by one.

[0177] (4) Antenna port

[0178] Antenna port can also be referred to as port for short. Antenna port can be understood as a transmitting antenna recognized by a receiving device, or a transmitting antenna that can be distinguished in space. Unless otherwise specified, the antenna ports in the embodiments of the present application refer to the ports of logical antennas, not the ports of physical antennas. For example, the reference signal transmitted by the network device through antenna port A can be used by the terminal device to estimate the characteristics of the channel from antenna port A to the terminal device.

[0179] An antenna port group may also be referred to as a port group, and may also be understood as an antenna port set or an antenna port array. An antenna port group may consist of one or more antenna ports.

[0180] (5) Code division multiplexing (CDM)

[0181] Multiple antenna ports can share time and frequency resources by using orthogonal cover code (OCC) sequences in the time domain and frequency domain, which is called CDM. In addition, it can also be implemented by other sequences, which is not limited in this application.

[0182] Exemplarily, CDM may include four types:

[0183] Type 1.noCDM: does not use code division multiplexing;

[0184] Type 2.CDM2: No multiplexing in the time domain, only multiplexing in the frequency domain, occupying two subcarriers in the frequency domain. The corresponding mapping diagram is as follows Figure 2A In a resource block, in the same CDM group, two ports use the same two consecutive subcarriers, and the two ports superimpose different OCC codes on the time-frequency resources, as shown in Figure 2A As shown, the first port superimposes +1 and +1 on the two subcarriers respectively, and the second port superimposes +1 and -1 on the two subcarriers respectively;

[0185] Type 3.CDM4: Multiplexing in both time and frequency domains, occupying two subcarriers in the frequency domain and two symbols in the time domain. The corresponding mapping diagram is as follows Figure 2B In a resource block, in the same CDM, four ports use the same two consecutive subcarriers and two consecutive symbols, and the four ports superimpose different OCC codes on the time-frequency resources, as shown in Figure 2B As shown, the first port superimposes +1 and +1 on the two symbols on the first subcarrier, and superimposes +1 and +1 on the two symbols on the second subcarrier, respectively. The second port superimposes +1 and -1 on the two symbols on the first subcarrier, and superimposes +1 and -1 on the two symbols on the second subcarrier, respectively, and so on.

[0186] Type 4.CDM8: Multiplexing in both time and frequency domains, occupying two subcarriers in the frequency domain and four symbols in the time domain. The corresponding mapping diagram is as follows Figure 2C In a resource block, in the same CDM, eight ports use the same two consecutive subcarriers and four consecutive symbols, and the eight ports superimpose different OCC codes on the time-frequency resources, as shown in Figure 2C As shown, the first port superimposes +1, +1, +1 and +1 on the four symbols on the first subcarrier, and superimposes +1, +1, +1 and +1 on the four symbols on the second subcarrier. The second port superimposes +1, +1, +1 and +1 on the four symbols on the first subcarrier, and -1, -1, -1 and -1 on the four symbols on the second subcarrier, and so on.

[0187] For the current CSI-RS resources, only 32 ports are supported at most, and the ports corresponding to the CSI-RS resources are in the following order:

[0188] p = 3000 + s + jL;

[0189] j=0,1,...,N / L-1;

[0190] s=0,1,...,L-1;

[0191] Wherein, p represents the port index of the CSI-RS resource, j represents the index of the CDM group of the CSI-RS resource, s represents the index of the sequence within the CDM group of the CSI-RS resource, N represents the total number of ports corresponding to the CSI-RS resource, and L represents the size of the CDM group of the CSI-RS resource. For the convenience of description, the above formula is hereinafter referred to as Formula 0.

[0192] Exemplarily, the network device can configure the number of ports N1 in the first dimension and the number of ports N2 in the second dimension in the codebook configuration (CodebookConfig), N=2N1N2, N is the number of ports corresponding to the CSI-RS resource. The ports corresponding to the CSI-RS resource are arranged in the order of the second dimension first, then the first dimension, and finally the polarization direction. Exemplarily, the first dimension is the horizontal direction, and the second dimension is the vertical direction, N1=8, N2=2, wherein the horizontal direction can also be referred to as the horizontal dimension, and the vertical dimension can also be referred to as the vertical direction. Figure 3 , which is a schematic diagram of an arrangement of ports corresponding to CSI-RS resources supporting 32 ports. Figure 3 Each cross in the figure represents a pair of dual-polarized antennas.

[0193] exist Figure 3 In the example, assuming that C=0, the port index starts from 0, and the port index of the port located in the first row and the first column of the first polarization direction is determined in the order of vertical direction, then horizontal direction and finally polarization direction as 0, the port index of the port located in the first row and the first column of the first polarization direction is 1, the port index of the port located in the first row and the second column of the first polarization direction is 2, and the port index of the port located in the second row and the second column of the first polarization direction is 3. By analogy, the port index of the port located in the first row and the eighth column of the first polarization direction is 14, the port index of the port located in the second row and the eighth column of the first polarization direction is 15, the port index of the port located in the first row and the first column of the second polarization direction is 16, and the port index of the port located in the second row and the first column of the second polarization direction is 17. By analogy, the port index of the port located in the first row and the eighth column of the second polarization direction is 30, and the port index of the port located in the second row and the eighth column of the second polarization direction is 31.

[0194] If the number of ports supported by a single CSI-RS resource is expanded from 32 to 64 or more, network devices need to significantly change their existing implementations to support the transmission of CSI-RSs with a larger number of ports. At the same time, terminal devices also need to significantly change their existing implementations to support the measurement of CSI-RSs with a larger number of ports.

[0195] In addition, in the current coherent joint transmission (CJT), the network device can configure multiple CSI-RS resources for the terminal device, each CSI-RS resource corresponds to a transmission reception point (TRP), and the terminal device will perform joint measurement based on the channels of the TRPs corresponding to these multiple CSI-RS resources. According to the current CJT scheme, one CSI-RS resource corresponds to one TRP, and different CSI-RS resources correspond to different TRPs. Or it can be described as follows: a port of a CSI-RS resource corresponds to one TRP, and ports of different CSI-RS resources correspond to different TRPs, or a port of a CSI-RS resource belongs to one TRP, and ports of different CSI-RS resources belong to different TRPs.

[0196] But in fact, these different CSI-RS resources can correspond to the same TRP, or, due to the strong correlation between channels, these different CSI-RS resources can be regarded as corresponding to one TRP. The current CJT scheme cannot correspond different CSI-RS resources to the same TRP, so there is redundancy in the CSI feedback information, the feedback overhead is large, and there is room for further optimization. For example, assuming that 4 CSI-RS resources correspond to 4 TRPs, the terminal device needs to feedback CSI for each TRP, that is, feedback 4 CSIs, so the feedback overhead is large.

[0197] Based on the above Figure 1 The network system architecture shown in the figure and the contents of the above-mentioned related technical introduction, the embodiment of the present application provides a possible resource configuration method, and the execution subject of the following resource configuration method is introduced by taking the network device and the terminal device as an example. For example, the network device can be the above-mentioned Figure 1 The access network device 110a or the access network device 110b in the embodiment. The terminal device may be the aforementioned Figure 1 Any terminal 120 shown. In addition, it should be understood that the network device can also be replaced by a communication device having a network device function or a chip, unit or module inside a communication device having a network device function. The terminal device can also be replaced by a communication device having a terminal device function or a chip, unit or module inside a communication device having a terminal device function.

[0198] Figure 4The following is a possible flow chart of a resource configuration method provided by an embodiment of the present application. Figure 4 As shown, the method includes:

[0199] Step 400: The network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device.

[0200] The first indication information is used to indicate M reference signal resources, among the ports corresponding to the M reference signal resources, the minimum port index is 0+C, the maximum port index is K-1+C, K is the sum of the number of ports corresponding to the M reference signal resources, M is an integer greater than or equal to 2, C is a constant, and K is an integer greater than 32. Exemplarily, the value of C may be 3000 or other values, the value of C may be a constant predefined by the protocol, or a constant determined by the network device and indicated to the terminal device, which is not limited in this application.

[0201] Among them, among the ports corresponding to the M reference signal resources, the minimum port index is 0+C, and the maximum port index is K-1+C. It can also be understood that, among the ports corresponding to the M reference signal resources, the difference between the maximum port index and the minimum port index is K-1. Therefore, the terminal device and the network device can determine that the ports corresponding to the M reference signal resources correspond to the same TRP, rather than the ports corresponding to the M reference signal resources corresponding to M TRPs. Or it can be described as, the terminal device and the network device can correspond the ports corresponding to the M reference signal resources to the same TRP; or, the terminal device and the network device can assign the ports corresponding to the M reference signal resources to the same TRP; or, the terminal device and the network device can determine that the ports corresponding to the M reference signal resources belong to the same TRP.

[0202] Exemplarily, any two reference signal resources among the M reference signal resources have different port indexes. It can also be understood that any two reference signal resources among the M reference signal resources do not have the same port index.

[0203] It can be understood that each reference signal resource corresponds to at least one port, and the port indexes corresponding to the at least one port are different. Exemplarily, the first reference signal resource corresponds to X ports, and the X ports correspond to the X port indexes one-to-one, and the second reference signal resource 2 corresponds to Y ports, and the Y ports correspond to the Y port indexes one-to-one, wherein X and Y are positive integers, the first reference signal resource and the second reference signal resource are any two reference signal resources among the M reference signal resources, and the X port indexes and the Y port indexes are different.

[0204] For example, assuming that the network device is configured with 4 reference signal resources, each reference signal resource supports 32 ports, then according to the above formula 0, the port index corresponding to each reference signal resource is from C to C+31, so any two different reference signal resources among the 4 reference signal resources have the same port index. Each reference signal resource includes a port index s, where C is the port index and s is an integer.

[0205] However, using the method provided by the present application, it is assumed that the network device is configured with 4 reference signal resources, each reference signal resource supports 32 ports, and among the ports corresponding to the 4 reference signal resources, the minimum port index is C and the maximum port index is 127+C. Therefore, any two different reference signal resources among the 4 reference signal resources do not have the same port index, or in other words, the port indexes of any two different reference signal resources are different. Alternatively, it can be described as that the 4 reference signal resources correspond to a total of 128 ports, and the port indexes corresponding to these 128 ports are different from each other.

[0206] Exemplarily, the first indication information may be carried by NZP-CSI-RS-ResourceSet.

[0207] Step 410: The network device sends a reference signal on M reference signal resources. Correspondingly, the terminal device receives a reference signal on the M reference signal resources.

[0208] Step 420: The terminal device sends CSI to the network device, and correspondingly, the network device receives CSI from the terminal device. The CSI is determined according to the reference signal in step 410.

[0209] Exemplarily, after the network device sends a reference signal on M reference signal resources, the terminal device determines a CSI according to the received reference signal and reports the CSI to the network device.

[0210] Through the above method, the network device can configure M reference signal resources, and the total number of ports corresponding to these reference signal resources is greater than 32. Since the minimum port index is 0+C and the maximum port index is K-1+C among the ports corresponding to these reference signal resources, it is possible to uniformly number the port indexes of the ports corresponding to these reference signal resources instead of individually numbering the port indexes of the ports corresponding to each reference signal resource. This allows the network device and the terminal device to determine that the ports corresponding to the M reference signal resources correspond to the same TRP, and the M reference signal resources can support a larger number of antenna ports, which can be applicable to FDD systems with antenna arrays with more than 32 antenna ports.

[0211] Since the terminal device determines that the ports corresponding to the M reference signal resources correspond to the same TRP, the terminal device only needs to report one CSI for the quantized reporting of the channels of one TRP. Compared with the CJT solution, the terminal device needs to report M CSIs for the quantized reporting of the channels of M TRPs, which can save feedback overhead. In addition, the CSI can reflect the complete spatial dimension characteristics and can more accurately reflect the channel characteristics.

[0212] Further, in a possible implementation, the network device may also send third indication information to the terminal device, where the third indication information indicates the number of ports N1 in the first dimension and / or the number of ports N2 in the second dimension, where N1 and N2 are positive integers, and K=2N1*N2. Exemplarily, the third indication information may be carried by a codebook configuration.

[0213] Among them, when the third indication information indicates the number of ports N1 of the first dimension, or the number of ports N2 of the second dimension, the terminal device can also calculate the number of ports of another dimension that is not indicated according to K=2N1*N2. For example, when the third indication information indicates the number of ports N1 of the first dimension, but does not indicate the number of ports of the second dimension, the terminal device can calculate the number of ports N2 of the second dimension according to the number of ports N1 of the first dimension and K=2N1*N2. For another example, when the third indication information indicates the number of ports N2 of the second dimension, but does not indicate the number of ports of the first dimension, the terminal device calculates the number of ports N1 of the first dimension according to the number of ports N1 of the first dimension and K=2N1*N2. The network device and the terminal device can determine the ports corresponding to the M reference signal resources and the corresponding port indexes according to the number of ports N1 of the first dimension, the number of ports N2 of the second dimension and the polarization direction. It can also be described as follows: the specific arrangement of ports corresponding to the M reference signal resources, or the topological structure of a group of ports corresponding to the M reference signal resources, or the antenna array corresponding to the M reference signal resources can be determined based on the number of ports N1 in the first dimension, the number of ports N2 in the second dimension, and the polarization direction.

[0214] Exemplarily, assuming that the first dimension is the horizontal direction and the second dimension is the vertical direction, it can be seen from the above that K is the sum of the number of ports corresponding to the M reference signal resources, that is, the M reference signal resources correspond to K ports in total, then the K ports can be arranged in the order of the second dimension first, the first dimension second, and the polarization direction last, or the K ports can be arranged in the order of the first dimension first, the second dimension second, and the polarization direction last, and then the specific arrangement of the K ports can be determined. It can be understood that the K ports can also be arranged in other orders, and this application does not limit this.

[0215] Exemplarily, the following method 3 is used to arrange the ports of M reference signal resources, and the port arrangement of each reference signal resource corresponds one-to-one to the arrangement of some ports in the K ports. That is, the M reference signal resources correspond to a total of K ports, and the ports included in the port group corresponding to each reference signal resource correspond one-to-one to some ports in the K ports, such as Fig. 9 As shown, exemplary, Fig. 9 The K ports are arranged in the order of the second dimension first, the first dimension second, and the polarization direction last, where the first reference signal resource corresponds to ports 0 to 15 of the first polarization direction and ports 64 to 79 of the second polarization direction. It can be considered that the configuration n1, n2 of the reference signal resource and the position of the reference signal in the entire K ports can determine the port arrangement of the reference signal resource, and its port number corresponds one by one to the port number of the same position in the entire K ports. In other words, the port index p corresponding to the reference signal resource with sequence number m m The port number n1 of the port group corresponding to each reference signal resource in the first dimension, the port number n2 of the port group corresponding to each reference signal resource in the second dimension, and the position of the port group corresponding to the reference signal resource with sequence number m in the port groups corresponding to the M reference signal resources are obtained. For details, please refer to the following formula A, formula B., formula A', formula B' and formula C.

[0216] In the present application, n1 represents the number of ports of the port group corresponding to each reference signal resource in the first dimension in one polarization direction, which can also be referred to as the number of ports of the port group corresponding to each reference signal resource in the first dimension. n2 represents the number of ports of the port group corresponding to each reference signal resource in the second dimension in one polarization direction, which can also be referred to as the number of ports of the port group corresponding to each reference signal resource in the second dimension. N1 represents the number of ports in the first dimension in one polarization direction, which can also be referred to as the number of ports in the first dimension, and N2 represents the number of ports in the second dimension in one polarization direction, which can also be referred to as the ports in the second dimension.

[0217] Exemplarily, when n2=N2, each polarization direction in each reference signal resource is arranged in the order of the second dimension first and the first dimension second, or each polarization direction in each reference signal resource is arranged in the order of the first dimension first and the second dimension second. Among them, the ports of the first polarization direction of all reference signal resources are arranged first, and then the ports of the second polarization direction of all reference signal resources are arranged. Refer to the following Fig. 9, the order is, arrange the first polarization direction port of the first reference signal resource, the first polarization direction port of the second reference signal resource, …, the first polarization direction port of the Mth reference signal resource, the second polarization direction port of the first reference signal resource, …, the second polarization direction port of the Mth reference signal resource.

[0218] Exemplarily, when n1=N1, each polarization direction within each reference signal resource is arranged in sequence according to the second dimension or the first dimension. Among them, the ports of the first polarization direction of all reference signal resources are arranged first, and then the ports of the second polarization direction of all reference signal resources are arranged. Referring to the following figure, the order is to arrange the first reference signal resource's first polarization direction first column n2 ports, the second reference signal resource's first polarization direction first column n2 ports,…, the Mth reference signal resource's first polarization direction first column n2 ports, the first reference signal resource's first polarization direction second column n2 ports,…, the Mth reference signal resource's first polarization direction second column n2 ports,…, arrange the first reference signal resource's first polarization direction first column n2 ports, the second reference signal resource's first polarization direction first column N1 n2 ports,…, the Mth reference signal resource's first polarization direction first column N1 n2 ports, the second reference signal resource's first polarization direction first column N1 n2 ports,…, the Mth reference signal resource's first polarization direction first column N1 n2 ports The second polarization direction port of the reference signal resource, the first reference signal resource, the first column n2 ports of the second polarization direction, the second reference signal resource, the first column n2 ports of the second polarization direction, ..., the first column n2 ports of the second polarization direction of the Mth reference signal resource, the second column n2 ports of the second polarization direction of the first reference signal resource, the second column n2 ports of the second polarization direction of the second reference signal resource, ..., the second column n2 ports of the second polarization direction of the Mth reference signal resource, ..., the second column N1 n2 ports of the second polarization direction of the first reference signal resource, the second column N1 n2 ports of the second polarization direction of the second reference signal resource, ..., the second column N1 n2 ports of the second polarization direction of the Mth reference signal resource. For example, Fig.10 shown.

[0219] Exemplarily, when the number of ports N1 in the first dimension is the same as the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, and / or the number of ports N2 in the second dimension is the same as the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, K, N1, N2, n1 and n2 satisfy one or more of the following corresponding relationships:

[0220] When K = 48, N1 = 8, N2 = 3, n1 = 4, n2 = 3; or,

[0221] When K=48, N1=8, N2=3, n1=8, n2=1; or

[0222] When K = 48, N1 = 6, N2 = 4, n1 = 6, n2 = 2; or,

[0223] When K=64, N1=16, N2=2, n1=8, n2=2; or,

[0224] When K=64, N1=16, N2=2, n1=16, n2=1; or,

[0225] When K=64, N1=8, N2=4, n1=4, n2=4; or,

[0226] When K=64, N1=8, N2=4, n1=8, n2=2; or,

[0227] When K = 128, N1 = 16, N2 = 4, n1 = 4, n2 = 4; or,

[0228] When K = 128, N1 = 16, N2 = 4, n1 = 16, n2 = 1; or,

[0229] When K=128, N1=8, N2=8, n1=8, n2=2.

[0230] According to the port allocation method, the terminal can use one or more reference signal resources to perform channel measurement. According to the reference signal resource configuration supported in the existing protocol, the following correspondence between K, N1, N2 and n1, n2 can be supported. It can be understood that the following Table a, Table b and Table c are only examples and are not intended to limit the present application.

[0231] Form a

[0232]

[0233] Optionally, when only N1=n1 or N2=n2 is supported, K, N1, N2, n1 and n2 satisfy the following corresponding relationship, which may be Table b or Table c.

[0234] Form b

[0235]

[0236] Form c

[0237]

[0238] Therefore, the network device determines the specific arrangement of the ports corresponding to the M reference signal resources by configuring the number of ports N1 of the first dimension and the number of ports N2 of the second dimension.

[0239] Exemplarily, the port index corresponding to each reference signal resource among the M reference signal resources can be determined by, but not limited to, the following methods 1 to 3. It should be noted that the following description only takes the reference signal resource with a sequence number of m among the M reference signal resources as an example, 0≤m≤M-1, m is an integer, and therefore the reference signal resource with a sequence number of m can be any reference signal resource among the M reference signal resources. It should be noted that in the present application, the sequence numbers corresponding to the M reference signal resources respectively start from 0, and the sequence number range is from 0 to M-1. In addition, the sequence numbers corresponding to the M reference signal resources respectively can also start from 1, and the sequence number range is from 1 to M. The following description only takes the sequence numbers corresponding to the M reference signal resources respectively starting from 0 as an example, and is not intended to be a limitation of the present application. It can be understood that the following indexes are also described by taking starting from 0 as an example, and can also start from 1, and the present application does not limit this.

[0240] In a possible implementation, the sequence numbers corresponding to the M reference signal resources are determined according to the identifiers corresponding to the M reference signal resources, or according to the configuration order of the M reference signal resources. For example, the sequence numbers corresponding to the M reference signal resources can be determined from large to small, or from small to large, according to the identifiers corresponding to the M reference signal resources. It can be understood that the above method of determining the sequence numbers corresponding to the M reference signal resources is only an example, and the sequence numbers corresponding to the M reference signal resources can also be determined by other methods, which is not limited in this application.

[0241] Method 1: The port index p corresponding to the reference signal resource with sequence number m m It is obtained according to the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the number of ports corresponding to the reference signal resources with sequence number less than or equal to m.

[0242] In one possible implementation, p m The corresponding relationship between the index of the CDM group of the reference signal resource with a sequence number of m, the index of the sequence within the CDM group of the reference signal resource with a sequence number of m, the size of the CDM group of the reference signal resource with a sequence number of m, and the number of ports corresponding to the reference signal resource with a sequence number less than or equal to m can be expressed by a formula, or by other means, such as a table. When the corresponding relationship is presented in a table, the table may include p m, the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, and optionally, the table may also include the size of the CDM group of the reference signal resource with sequence number m, the sum of the number of ports corresponding to the reference signal resources with sequence numbers less than m, and the number of ports corresponding to the reference signal resources with sequence number equal to m.

[0243] For example, p m The corresponding relationship between the index of the CDM group of the reference signal resource with a sequence number of m, the index of the sequence within the CDM group of the reference signal resource with a sequence number of m, the size of the CDM group of the reference signal resource with a sequence number of m, and the number of ports corresponding to the reference signal resource with a sequence number less than or equal to m is:

[0244]

[0245] Wherein, j represents the index of the CDM group of the reference signal resource with sequence number m, s represents the index of the sequence in the CDM group of the reference signal resource with sequence number m, 0≤s≤L m -1, N m Indicates the number of ports of the reference signal resource with sequence number m, L m represents the size of the CDM group of the reference signal resource with sequence number m, is the sum of the number of ports corresponding to the reference signal resources with sequence numbers less than m, N k is the number of ports corresponding to the reference signal resource with sequence number k, j and s are integers. The above formula is referred to as Formula 1 hereinafter.

[0246] The size of the CDM group of the reference signal resource with sequence number m may also be configured through radio resource control (RRC) signaling. It can also be written as: 0≤s≤L m -1, can also be written as: s = 0, 1, ... L m -1.

[0247] It should be understood that the M reference signal resources are numbered starting from 1. When the numbering starts from 1, the summation range of the last term in Formula 1 is 1 to m. Formula 1 can be replaced by:

[0248]

[0249] By adopting the above-mentioned method 1, the port indexes corresponding to the M reference signal resources can be determined relatively simply. However, each reference signal resource cannot constitute an independent dual-polarized antenna array, so the reuse of the reference signal resources cannot be achieved.

[0250] Mode 2: The number of ports corresponding to each of the M reference signal resources is N, K = M*N, N is a positive integer. The port index corresponding to the reference signal resource with sequence number m is p m It is obtained according to the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N.

[0251] It can be understood that the number of ports corresponding to the M reference signal resources is N, that is, the number of ports corresponding to the M reference signal resources is the same.

[0252] In one possible implementation, p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence in the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N can be expressed by a formula, or by other means, for example, a table. When the corresponding relationship is presented in a table, the table may include p m , an index of the CDM group of the reference signal resource with sequence number m, an index of the sequence within the CDM group of the reference signal resource with sequence number m, and optionally, the table may also include the size of the CDM group of the reference signal resource with sequence number m.

[0253] In one example, p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N is:

[0254] p m =C+s+jL m +mN Formula 2

[0255] Wherein, j represents the index of the CDM group of the reference signal resource with sequence number m, s represents the index of the sequence in the CDM group of the reference signal resource with sequence number m, 0≤s≤L m -1,L m represents the size of the CDM group of the reference signal resource with sequence number m, j and s are integers. The above formula is referred to as Formula 2 hereinafter.

[0256] The above formula 2 can be regarded as a simplified version of formula 1, that is, when the number of ports corresponding to the M reference signal resources is N, formula 1 can be simplified to formula 2.

[0257] It should be understood that the M reference signal resources are numbered starting from 1. When 1≤m≤M, Formula 2 can be replaced by:

[0258] p m =C+s+jL m +(m-1)N

[0259] Using the above example, when the number of ports corresponding to the M reference signal resources is the same, the port indexes corresponding to the M reference signal resources can be determined relatively simply. In which, each reference signal resource cannot constitute an independent dual-polarized antenna array, so the multiplexing of the reference signal resources cannot be achieved.

[0260] In another example, p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, and the value of N is:

[0261] p m =C+(s+jL m )M+m Formula 3

[0262] Wherein, j represents the index of the CDM group of the reference signal resource with sequence number m, s represents the index of the sequence in the CDM group of the reference signal resource with sequence number m, 0≤s≤L m -1,L m represents the size of the CDM group of the reference signal resource with sequence number m, j and s are integers. The above formula is referred to as Formula 3 hereinafter.

[0263] It should be understood that the M reference signal resources are numbered starting from 1. When the numbering starts from 1, Formula 3 can be replaced by:

[0264] p m =C+(s+jL m )M+m-1

[0265] The above formula 3 can be understood as follows: From the above, K is the sum of the number of ports corresponding to the M reference signal resources, that is, the M reference signal resources correspond to K ports in total, and the K ports are grouped into groups of 2M ports, and the following can be obtained: Group, where K=2N1N2. Exemplarily, it is assumed that the K ports are arranged in the order of the second dimension first, the first dimension, and the polarization direction last. For the 2M ports in each port group, a port group with M / min(N2,M) ports in the first dimension, min(N2,M) ports in the second dimension, and two polarization directions can be formed. In other words, a port group can occupy M positions, of which M / min(N2,M) positions are occupied in the first dimension and min(N2,M) positions are occupied in the second dimension. These M positions are arranged in the order of the second dimension first and then the first dimension, and the two antenna ports at the m+1th position (or position m) belong to the port corresponding to the reference signal resource with serial number m.

[0266] like Figure 5 As shown, assuming that the first dimension is the horizontal direction and the second dimension is the vertical direction, N1=8, N2=8. The number of ports corresponding to the four reference signal resources is 32, that is, the four reference signal resources correspond to a total of 128 ports. Grouping the 128 ports into groups of 2M=8 ports, we can get For each port group, a port group with a first dimension of M / min(N2,M)=1 port and a second dimension of min(N2,M)=4 ports can be formed, that is, each port group is composed of 8 antenna ports at four consecutive positions in the vertical direction. Since 1 position is occupied in the first dimension, the 4 positions occupied by each port group are arranged in the order of the second dimension, that is, in the order of the vertical direction. Therefore, in each port group, the two ports at the first position (position 0) in the vertical direction belong to the ports corresponding to the reference signal resource with sequence number 0, the two ports at the second position (position 1) in the vertical direction belong to the ports corresponding to the reference signal resource with sequence number 1, the two ports at the third position (position 2) in the vertical direction belong to the ports corresponding to the reference signal resource with sequence number 2, and the two ports at the fourth position (position 3) in the vertical direction belong to the ports corresponding to the reference signal resource with sequence number 3.

[0267] Depend on Figure 5 It can be seen that each column includes 8 positions, that is, 2 port groups can be formed. Through the above method, all ports in the first row and all ports in the fifth row belong to the ports corresponding to the reference signal resource with sequence number 0, all ports in the second row and all ports in the sixth row belong to the ports corresponding to the reference signal resource with sequence number 1, all ports in the third row and all ports in the seventh row belong to the ports corresponding to the reference signal resource with sequence number 2, and all ports in the fourth row and all ports in the eighth row belong to the ports corresponding to the reference signal resource with sequence number 3.

[0268] Therefore, the port corresponding to each reference signal resource can correspond to an array, which is a uniform dual-polarization array, and then the port corresponding to a single reference signal resource can also be used for separate quantization reporting, thereby realizing the reuse of reference signal resources. In other words, each of the M reference signal resources can be used as a separate measurement resource for terminal devices that do not support channel measurement of more than 32 ports. Considering that in actual deployment, due to different measurement capabilities of terminal devices, there are some terminal devices that only support reference signal resources of no more than 32 ports. Therefore, the above method can realize the reuse of reference signal resources and reduce the overhead of reference signal resources.

[0269] Using the above example, the formula of the port index is simple, easy to implement, and can achieve multiplexing of reference signal resources.

[0270] Mode 3: The number of ports corresponding to each of the M reference signal resources is N, K = M*N, N is a positive integer. The port index corresponding to the reference signal resource with sequence number m is p m According to the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, the value of N, the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, and the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension, K=2M*n1*n2, the port groups corresponding to the M reference signal resources respectively have the same number of ports in the first dimension, and the port groups corresponding to the M reference signal resources respectively have the same number of ports in the second dimension.

[0271] It can be understood that the number of ports corresponding to the M reference signal resources is N, that is, the number of ports corresponding to the M reference signal resources is the same.

[0272] In one possible implementation, p m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence in the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, the value of N, the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, and the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension can be expressed by a formula, or by other means, for example, a table. When the corresponding relationship is presented in a table, the table may include pm , the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, and the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension. Optionally, the table may also include the size of the CDM group of the reference signal resource with sequence number m, the value of N, the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, and the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension.

[0273] Exemplarily, the port index p corresponding to the reference signal resource with sequence number m is m The corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence within the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, the value of N, the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, and the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension is:

[0274] Formula A:

[0275]

[0276] Formula B:

[0277]

[0278] Where j represents the index of the CDM group, s represents the index of the sequence in the CDM group, 0≤s≤L m -1,L m represents the size of the CDM group of the reference signal resource with sequence number m, N1 and N2 are the number of ports in the first dimension and the number of ports in the second dimension respectively, h m Indicates the sequence number of the port group corresponding to the reference signal resource with sequence number m in the first dimension, v m represents the sequence number of the port group corresponding to the reference signal resource with sequence number m in the second dimension, The number of ports in the first dimension of the port group corresponding to each reference signal resource is n1, and the number of ports in the second dimension of the port group corresponding to each reference signal resource is n2. m 、h m 、v m , n1, n2 are integers, Indicates rounding down, and % indicates remainder operation.

[0279] When only N1=n1 or N2=n2 is considered, Formula A can be further simplified to Formula A', and Formula B can be further simplified to Formula B':

[0280] Formula A':

[0281]

[0282] Formula B':

[0283]

[0284] Consider only when N2=n2, the port index p corresponding to the reference signal resource with sequence number m m There is a corresponding relationship between the index of the CDM group of the reference signal resource with sequence number m, the index of the sequence in the CDM group of the reference signal resource with sequence number m, the size of the CDM group of the reference signal resource with sequence number m, the value of N, and the number of reference signal resources M. Specifically, it can be expressed as the following formula C and formula D.

[0285] Formula C:

[0286]

[0287] Formula D:

[0288]

[0289] Among them, h m and v m It is used to indicate the position of the port group corresponding to the reference signal resource with sequence number m in the port groups corresponding to the M reference signal resources.

[0290] In a possible implementation, the number of ports corresponding to the M reference signal resources is N, N m =N; and / or the size of the CDM groups corresponding to the M reference signal resources is L, L m =L.

[0291] like Figure 6 As shown, assuming that the first dimension is the horizontal direction and the second dimension is the vertical direction, N1=16, N2=4. The number of ports corresponding to the four reference signal resources is 32, that is, the four reference signal resources correspond to a total of 128 ports, wherein the number of ports of the port group corresponding to each reference signal resource in the first dimension is 8, and the number of ports in the second dimension is 2. Assuming that the four reference signal resources are arranged in the vertical direction first and then in the horizontal direction, the h corresponding to the reference signal resource with sequence number 0 is m and v m h m =0, vm = 0, the position of the reference signal resource with sequence number 0 is recorded as (0,0), and the h corresponding to the reference signal resource with sequence number 1 is m and v m h m =0, v m =1, the position of the reference signal resource with sequence number 1 is recorded as (0,1), and the h corresponding to the reference signal resource with sequence number 2 is recorded as m and v m h m =1,v m =0, the position of the reference signal resource with sequence number 2 is (1,0), and the h corresponding to the reference signal resource with sequence number 3 is m and v m h m =1,v m =1, and the position of the reference signal resource with sequence number 3 is recorded as (1,1). Therefore, the positions of the four reference signal resources, that is, the arrangement of the four reference signal resources, can be determined.

[0292] It should be understood that the arrangement order of the port groups corresponding to the M reference signal resources can be arranged in the order of the second dimension first and then the first dimension, or can be arranged in the order of the first dimension first and then the second dimension, or can be arranged in other ways as agreed by the protocol, or can be indicated by the network device through signaling.

[0293] The port groups corresponding to the M reference signal resources have the same number of ports in the first dimension, that is, the number of ports in the first dimension of the port group corresponding to each reference signal resource is n1. The port groups corresponding to the M reference signal resources have the same number of ports in the second dimension, that is, the number of ports in the second dimension of the port group corresponding to each reference signal resource is n2.

[0294] In a possible implementation, the network device may further send second indication information to the terminal device, where the second indication information indicates the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension and / or the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, where K=2M*n1*n2,

[0295] Among them, when the second indication information indicates the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension, or the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension, the terminal device can calculate the number of ports of the port group corresponding to each reference signal resource in another dimension according to K=2M*n1*n2.

[0296] Exemplarily, the second indication information may be carried by a resource configuration (e.g., CSI-ResourceConfig) or a reporting configuration (e.g., reportConfig) or a codebook configuration (e.g., codebookConfig). In addition, since the number of ports of the reference signal resources associated with these configurations is the same, the configurations of the M reference signal resources may share the same parameters. Therefore, it is only necessary to configure n1 and n2 once, without configuring n1 and n2 M times, thereby saving signaling overhead.

[0297] Therefore, the network device determines the specific arrangement of the ports corresponding to each reference signal resource, or the topological structure of the port group corresponding to each reference signal resource, or the port array corresponding to each reference signal resource by configuring the number of ports n1 of the port group corresponding to each reference signal resource in the first dimension and / or the number of ports n2 of the port group corresponding to each reference signal resource in the second dimension.

[0298] In the above-mentioned method 3, each reference signal resource corresponds to a dual-polarization array. Therefore, for a single reference signal resource, the existing codebook can be used for quantization feedback, that is, a single reference signal resource can be used for a separate quantization report, thereby realizing the reuse of reference signal resources. Therefore, each of the M reference signal resources can be used as a separate measurement resource for terminal devices that do not support channel measurement of more than 32 ports. Considering that in actual deployment, due to different measurement capabilities of terminal devices, there are some terminal devices that only support reference signal resources of no more than 32 ports. Therefore, the above-mentioned method can realize the reuse of reference signal resources and reduce the overhead of reference signal resources.
