Description

Communication method and communication apparatus

[0001] This application claims priority from the Chinese patent application No. 202410465061.9 filed on April 15, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] In the existing protocol, when the channel measurement is configured based on the aperiodic (AP) channel state information reference signal (CSI-RS) Doppler measurement, K non-zero power (NZP) CSI-RS resources are configured in one resource set, and the time interval of two consecutive AP-CSI-RS resources is m slots. Therefore, in the Doppler measurement, by periodically sending multiple CSI-RS resources, one of the multiple CSI-RS resources is used to perform a channel state measurement on a group of antenna ports, and the multiple CSI-RS resources are used to perform multiple channel state measurements on the group of antenna ports. Therefore, for Doppler measurement, multiple channel state measurements need to be performed on the group of antenna ports. Because the codebook in the existing standard only supports the measurement of up to 32 antenna ports included in a group of ports, in one Doppler measurement, each channel state measurement can only use one CSI-RS resource to evaluate the channel state of up to 32 antenna ports.

[0004] However, with the increase of the number of base station antennas, CSI measurement of larger ports can provide greater spectral efficiency and system capacity of the downlink. Because in the existing protocol, a single station supports up to one resource for one CSI measurement of up to 32 antenna ports. In order to be compatible with existing users, the protocol specifies that the large port is divided into several partial ports, and a CSI-RS resource is allocated for each partial port to perform measurement of the large port. Therefore, if larger antenna port numbers (such as 128 antenna ports) are to be supported for Doppler measurement, the large port needs to be divided into multiple antenna port groups, and multiple channel state measurements need to be performed on the multiple antenna port groups. The terminal needs to know the resource configuration information of each partial port in each measurement.

[0005] In addition, a terminal needs a certain processing time to receive channel measurement information and report corresponding CSI, and the processing time for up to 32 ports is specified in the existing protocol. Since it is necessary to measure and process channel state information of more ports, the expansion of terminal processing time is an inevitable trend, so it is necessary to further specify the time from the end of port measurement to the start of CSI report.

[0006] Therefore, how to design a resource configuration scheme suitable for AP CSI-RS Doppler measurement of large ports and specify the time from the end of large port measurement to the start of CSI report has become a problem to be solved. SUMMARY

[0007] The present application provides a communication method, which can determine the resource configuration information constituting the entire large port measurement in Doppler measurement, and can also determine the time from the end of large port measurement to the start of CSI report.

[0008] In a first aspect, a communication method is provided, which includes: receiving resource configuration information, the resource configuration information being used to indicate resources used by each antenna port group in each channel state measurement in M channel state measurements for K antenna port groups, wherein the resources used by the same antenna port group in each channel state measurement are different, and the resources used by any two antenna port groups in the same channel state measurement are different, M≥2, K≥2, each antenna port group includes at least one antenna port; and performing M channel state measurements on the K antenna port groups according to the resource configuration information.

[0009] Optionally, the resources used by each antenna port group in each channel state measurement in M channel state measurements for K antenna port groups can also be pre-defined by a protocol.

[0010] Based on the above scheme, the resource configuration information is used to indicate the resource used by each antenna port group in each measurement, so that the K resources used by each antenna port group in each measurement in the M channel state measurements of the K antenna port groups can be determined according to the resource configuration information. Further, the KxM resources for the M channel state measurements of the K antenna port groups can be determined, that is, the resources used by the K antenna port groups in each measurement in the Doppler measurement are determined, so that the M channel state measurements of the K antenna port groups are performed. For example, when performing multiple channel state measurements on a large port (e.g., 128 antenna ports), the large port is divided into several partial ports (e.g., 32 antenna ports), and the partial port corresponds to an antenna port group, that is, multiple channel state measurements are performed on several antenna port groups. According to the indication of the resource configuration information, the resource used by each antenna port group in each channel state measurement in the several antenna port groups can be determined, that is, the resource configuration scheme for the Doppler measurement of a larger port is improved.

[0011] In some implementations of the first aspect, the resource configuration information is used to indicate the correspondence between the M channel state measurements and the M resource sets, wherein each resource set includes K resources, and the K resources are used for one of the M channel state measurements of the K antenna port groups, and the K resources in each resource set have a mapping relationship with the K antenna port groups.

[0012] Based on the above scheme, the resource configuration information is used to indicate the correspondence between the M channel state measurements and the M resource sets, so that the mth resource set corresponding to the mth channel state measurement can be determined according to the resource configuration information, and the mth resource set includes K resources. According to the mapping relationship between the K resources and the K antenna port groups, the kth antenna port group corresponding to the kth resource in the mth resource set can be determined, m∈[1,M], k∈[1,K]. That is, the resource used by each antenna port group in each channel state measurement can be determined according to the resource configuration information, so that the resource configuration scheme used by the multiple antenna port groups in each channel state measurement in the AP CSI-RS Doppler measurement is improved.

[0013] In some implementations of the first aspect, the K resources are arranged in a first order according to the identifiers of the resources, the K antenna port groups are arranged in a second order, and the mapping relationship is that the ith resource in the first order corresponds to the ith antenna port in the second order, i∈[1,K].

[0014] Optionally, the first order and the second order are indicated by a network device or predefined by a protocol.

[0015] Exemplarily, the first order is to arrange the K resources in ascending order or descending order.

[0016] Exemplarily, the second order comprises: in the AP CSI-RS Doppler measurement, each time the channel state measurement is performed on 128 antenna ports, in each channel state measurement, the 128 antenna ports are divided into 4 antenna port groups, that is, each time the channel state measurement is performed on 4 antenna port groups. If the port identifiers corresponding to the 128 antenna ports are 0-127, the second order can be: 0-31 are the first group of antenna ports, 32-63 are the second group of antenna ports, 64-95 are the third group of antenna ports, and 96-127 are the fourth group of antenna ports. Alternatively, the second order can also be: 96-127 are the first group of antenna ports, 64-95 are the second group of antenna ports, 32-63 are the third group of antenna ports, and 0-31 are the fourth group of antenna ports. The present application does not limit this.

[0017] Based on the above scheme, by sorting the K resources according to the first order and sorting the K antenna port groups according to the second order, it can be determined that the i-th resource in the first order corresponds to the i-th antenna port group in the second order, thereby perfecting the resource configuration scheme used by each antenna port group in the multiple antenna port groups of each channel state measurement in the AP CSI-RS Doppler measurement.

[0018] In combination with the first aspect, in some implementations of the first aspect, the resource configuration information is used to indicate K×M resources, the K×M resources correspond to a resource set, the K×M resources are used for M times of channel state measurement of K antenna port groups, the K×M resources are divided into K resource groups, the K resource groups correspond to the K antenna port groups in one-to-one correspondence, and each resource group includes M resources, the M resources correspond to the M times of channel state measurement in one-to-one correspondence.

[0019] In combination with the first aspect, in some implementations of the first aspect, the resource configuration information is used to indicate K×M resources, the K×M resources correspond to a resource set, the K×M resources are used for M times of channel state measurement of K antenna port groups, the K×M resources are divided into M resource groups, the M resource groups correspond to the M times of channel measurement in one-to-one correspondence, and each resource group includes K resources, the K resources in each resource set correspond to the K antenna port groups in one-to-one correspondence.

[0020] Based on the above scheme, according to the one-to-one correspondence between the K resource groups and the K antenna port groups, and the one-to-one correspondence between the M resources in each resource group and the M measurements, or according to the one-to-one correspondence between the M resource groups and the M measurements, and the one-to-one correspondence between the K resources included in each resource group and the K antenna port groups, the resource used by each antenna port group in each channel state measurement can be determined, thereby perfecting the resource configuration scheme used by each antenna port group in each channel state measurement in AP CSI-RS Doppler measurement.

[0021] In combination with the first aspect, in some implementations of the first aspect, the resource configuration information is used to indicate the correspondence between the K resources corresponding to each channel state measurement and the K antenna port groups in M channel state measurements, the KxM resources corresponding to the M channel state measurements of the K antenna port groups correspond to a resource set, and the KxM resources are used for the M channel state measurements of the K antenna port groups.

[0022] The resource configuration information is used to indicate the correspondence between the M resources corresponding to each antenna port group and the M channel state measurements in the K antenna port groups, and the KxM resources corresponding to the K antenna port groups correspond to a resource set, and the KxM resources are used for the M channel state measurements of the K antenna port groups.

[0023] Based on the above scheme, the resource configuration information is used to indicate the correspondence between the K resources corresponding to each channel state measurement and the K antenna port groups in M channel state measurements, and the resource configuration information is used to determine the resource used by each antenna port group in each channel state measurement; and the resource configuration information is used to indicate the correspondence between the M resources corresponding to each antenna port group and the M channel state measurements in the K antenna port groups, and the resource configuration information is used to determine the resource used by each antenna port group in each channel state measurement, thereby perfecting the resource configuration scheme used by each antenna port group in each channel state measurement in AP CSI-RS Doppler measurement.

[0024] In combination with the first aspect, in some implementations of the first aspect, the resource configuration information is also used to indicate the K resources corresponding to each resource group in the M resource groups.

[0025] Based on the above scheme, the resource configuration information indicates the corresponding K resources in each resource group, that is, according to the resource indication information, the corresponding K resources in each resource group can be determined, thereby perfecting the resource configuration scheme used by each antenna port group in each channel state measurement in AP CSI-RS Doppler measurement.

[0026] In some implementations of the first aspect, the K*M resources are divided into M groups according to a second rule, including: the K*M resources are arranged in a third order, and the nthK+1th resource to the nthK+Kth resource in the third order are divided into the nth group of the M groups, n [0, M-1].

[0027] Optionally, the third order is indicated by the network device or predefined by a protocol.

[0028] For example, the third order is ascending or descending arrangement of the K*M resources.

[0029] Based on the above scheme, the K*M antenna ports can be comprehensively sorted according to the third order, and the nthK+1th resource to the nthK+Kth resource are divided into the nth group of the M groups. For example, the resource configuration information indicates 16 resources, and the third order is ascending arrangement of the 16 resources. The 1st resource to the 4th resource are a group, the 5th resource to the 8th resource are a group, the 9th resource to the 12th resource are a group, and the 13th resource to the 16th resource are a group, that is, the 16 resources are divided into 4 groups, 4 resources for one, each group corresponds to one channel state measurement, and each resource in each group corresponds to one antenna port group, so that the resource configuration scheme used by each antenna port group in each channel state measurement in AP CSI-RS Doppler measurement can be determined.

[0030] In some implementations of the first aspect, the resource configuration information is used to indicate the correspondence between the K antenna port groups and K resource sets, wherein each resource set includes M resources, and the M resources in each resource set have a mapping relationship with the M channel state measurements.

[0031] Based on the above scheme, the resource configuration information is used to indicate the correspondence between the K antenna port groups and K resource sets, so the kth resource set corresponding to the kth antenna port group can be determined according to the resource configuration information, and the kth resource set includes M resources. According to the mapping relationship between the M resources and the M channel state measurements, the mth resource in the kth resource set corresponds to the mth channel state measurement, m [1, M], k [1, K]. That is, the resource used by each antenna port group in each channel state measurement can be determined according to the resource configuration information, so that the resource configuration scheme used by the multiple antenna port groups constituting each channel state measurement in AP CSI-RS Doppler measurement is perfected.

[0032] In some implementations of the first aspect, the M resources are arranged in a fourth order according to the identities of the resources, the M channel state measurements are arranged in a fifth order, and the mapping relationship is that an i th resource in the fourth order corresponds to an i th channel state measurement in the fifth order, i∈[1, M].

[0033] Optionally, the fourth order and the fifth order are indicated by the network device or predefined by a protocol.

[0034] For example, the fourth order is ascending or descending arrangement of the M resources.

[0035] For example, the fifth order is ascending arrangement of the M channel state measurements according to the measurement slot indexes corresponding to each measurement. In Doppler measurement, the M channel state measurements correspond to the M measurement slot indexes one by one, and are arranged in ascending order according to the M measurement slot indexes. For example, the first measurement corresponds to measurement slot #0, the second measurement corresponds to measurement slot #1, the third measurement corresponds to measurement slot #2, and the fourth measurement corresponds to measurement slot #3.

[0036] Based on the above scheme, by arranging the M resources in the fourth order and arranging the M channel state measurements in the fifth order, it can be determined that the i th resource in the fourth order corresponds to the i th channel state measurement in the fifth order, thereby perfecting the resource configuration scheme used by each antenna port group in each channel state measurement in AP CSI-RS Doppler measurement.

[0037] In some implementations of the first aspect, the K×M resources are divided into K resource groups, including that each resource in the K×M resources corresponds to one channel state measurement of at least one antenna port group in the M channel state measurements, the K×M resources are divided into M resource groups, each resource group includes K resources, each resource group corresponds to the same channel state measurement, and K resources in each resource group are arranged in a sixth order. The k th resource group in the K resource groups includes the k th resource arranged in the sixth order in each resource group, k∈[1, K].

[0038] Optionally, the sixth order is indicated by the network device or predefined by a protocol.

[0039] For example, the sixth order can be ascending or descending arrangement of the K resources.

[0040] Based on the above scheme, the corresponding K resources in each channel state measurement can be sorted in the sixth order, that is, the K resources in each of the M measurements are sorted in the sixth order respectively, and the sorted K resources corresponding to each of the M measurements are obtained, and the kth resource in the sorted K resources corresponding to each measurement is divided into a group. For example, the resource configuration information indicates 16 resources, and the sixth order is ascending arrangement of the 16 resources, the terminal can distinguish the corresponding 4 resources of the first measurement, the second measurement, the third measurement and the fourth measurement, and arrange the 4 resources corresponding to the four measurements in ascending order respectively. After sorting, the resource arranged first in the four measurements is taken as the first group, the resource arranged second is taken as the second group, and so on, and the division of the 4 resource groups is completed. The K resource groups correspond to K antenna port groups respectively, and the M resources in each resource group correspond to M measurements respectively, so that the resource used by each antenna port group in each channel state measurement can be determined, and the resource configuration scheme used by each antenna port group in each channel state measurement in the AP CSI-RS Doppler measurement is improved.

[0041] It should be noted that the sorting manners of the first order to the sixth order can be the same or different.

[0042] In combination with the first aspect, in some implementations of the first aspect, the mapping relationship is one-to-one correspondence between the M resources in each resource set and the M channel state measurements.

[0043] Based on the above scheme, the resource configuration information is used to indicate the correspondence between the K antenna port groups and the K resource sets, so the kth resource set corresponding to the kth antenna port group can be determined according to the resource configuration information, and the M resources are included in the kth resource set. Because the M resources are one-to-one corresponding to the M channel state measurements, that is, the mth resource in the kth resource set corresponds to the mth channel state measurement, m∈[1,M], k∈[1,K]. Through the method, the resource used by each antenna port group in each channel state measurement can be determined, and the resource configuration scheme used by the multiple antenna port groups constituting each channel state measurement in the AP CSI-RS Doppler measurement is improved.

[0044] In combination with the first aspect, in some implementations of the first aspect, the measurement start time of each resource in the each channel state measurement is the same.

[0045] Optionally, the measurement start time of each resource in the each channel state measurement is different.

[0046] Based on the above scheme, the measurement start time of each resource is guaranteed to be consistent in a single measurement. For example, if the channel state measurement is performed on 128 antenna ports, and the 128 antenna ports are divided into four antenna port groups, then multiple resources are used to measure the four antenna port groups simultaneously in a single channel state measurement. This improves the resource configuration scheme used by multiple antenna port groups in AP CSI-RS Doppler measurement and each channel state measurement.

[0047] In combination with the first aspect, in certain implementations of the first aspect, the time interval between the end time of the i-th channel state measurement and the start time of the i+1-th channel state measurement is the same; or, the end time of the i-th channel state measurement is the same as the start time of the i+1-th channel state measurement, i∈[1,M].

[0048] Optionally, the time interval between the end time of the i-th channel state measurement and the start time of the i+1-th channel state measurement is different; or, the end time of the i-th channel state measurement is different from the start time of the i+1-th channel state measurement, i∈[1,M].

[0049] Based on the above scheme, the time interval between each channel state measurement is designed to be the same, so that the time interval between each measurement remains constant; alternatively, the end time of each channel state measurement is the same as the time of the next channel state measurement, so that the measurement can be performed continuously and uninterrupted. This improves the process of using resources to perform channel state measurements on multiple antenna port groups in AP CSI-RS Doppler measurement.

[0050] In combination with the first aspect, in certain implementations of the first aspect, the time domain position of the resource is the same, but the frequency domain position is different; or, the frequency domain position of the resource is the same, but the time domain position is different; or, both the time and frequency positions of the resource are different.

[0051] Based on the above scheme, different resources are designed to make the time-frequency location of resources more flexible, thereby improving the resource configuration scheme used in AP CSI-RS Doppler measurement and the multiple antenna port groups used in each channel state measurement.

[0117] For ease of understanding, the communication system to which the embodiments of the present application are applicable is introduced below. It should be understood that the following communication system is only an example, and the communication system to which the present application is applicable is not limited to this.

[0118] FIG. 1 is a schematic diagram of a communication system 100 to which embodiments of the present application are applicable. As shown in FIG. 1, the communication system 100 includes a radio access network 100. The radio access network 100 can be a next generation (for example, future communication or higher version) radio access network, or a conventional (for example, 5G, 4G, 3G or 2G) radio access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be connected to each other or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100.

[0119] In practical application, the wireless communication system can comprise multiple network devices simultaneously, or multiple terminal devices simultaneously, without limitation. One network device can serve one or more terminal devices simultaneously. One terminal device can access one or more network devices simultaneously. Embodiments of the present application do not limit the number of terminal devices and network devices comprised in the wireless communication system.

[0120] The 5G communication system has higher requirements on system capacity and spectrum efficiency. In the 5G communication system, the application of massive multi-antenna technology (Massive MIMO) plays a crucial role in improving the spectrum efficiency of the system. When MIMO technology is used, the base station needs to precode data before transmitting the data to the UE. How to precode needs to rely on channel state information (CSI), so accurate CSI feedback information is an important factor affecting system performance.

[0121] FIG. 2 is a schematic diagram of a basic process of obtaining CSI from a UE by a base station. In the FDD system, since the interval between the uplink and downlink frequency bands is greater than the bandwidth, the uplink and downlink channels do not have complete reciprocity. In the traditional FDD system, as described in FIG. 1, the user needs to feed back the CSI of the downlink channel to the base station. The specific process is shown as S210 to S240 in the figure, and the steps S210 to S240 are described as follows.

[0122] S210, the base station needs to first send signaling for channel measurement configuration to inform the UE of the time and behavior of channel measurement.

[0123] S220, the base station sends a reference signal (RS) for channel measurement to the UE, and the RS is also called a pilot signal. S230, the UE measures according to the RS sent by the base station, calculates the final CSI feedback quantity, and feeds back the final obtained CSI to the base station. S240, the base station transmits data according to the CSI fed back by the UE. Among them, the base station determines the number of data transmission streams to the UE according to the rank indication (RI) fed back by the UE; the base station determines the modulation order of data transmission to the UE and the code rate of channel coding according to the channel quality indicator (CQI) fed back by the UE; the base station determines the pre-coding of data transmission to the UE according to the pre-coding matrix indication (PMI) fed back by the UE. RI, CQI and PMI are collectively referred to as CSI.

[0124] In a TDD system, the uplink channel and the downlink channel use the same frequency band, and thus have reciprocity. The base station can use the reciprocity of the channel to obtain the CSI of the downlink channel through the uplink channel, and then perform precoding. However, in some cases, for example, for a cell edge user, the estimation error of the uplink channel obtained by the base station is large due to the small transmission power of the user, and in this case, the precoding can also be determined based on the channel state information fed back by the terminal, and the specific process is similar to that of the FDD system.

[0125] In the existing protocol, when the channel measurement is configured as a Doppler measurement of aperiodic (AP) CSI-RS, K non-zero power (NZP) CSI-RS resources are configured in one resource set, where K>1, K can be configured as 4, 8 or 12, and the time interval of two consecutive AP-CSI-RS resources is m slots, m∈{1, 2}.

[0126] FIG. 3 is a schematic diagram of AP-CSI-RS Doppler measurement. As shown in FIG. 3, the diagram includes three parts, which are described below.

[0127] ① In the measurement window, the base station non-periodically transmits a plurality of CSI-RS to the UE, that is, the part shown in the dashed box in the figure, and the plurality of CSI-RS are used to obtain the CSI.

[0128] ② The UE needs to measure the plurality of CSI-RS to evaluate the channel state of the entire antenna port. The UE calculates the Doppler precoding matrix and the Doppler compression parameter according to the plurality of received CSI-RS.

[0129] ③ The UE feeds back the obtained Doppler precoding matrix to the base station, and the base station can determine the precoder for transmitting data to the UE according to the feedback Doppler precoding matrix.

[0130] Currently, only one CSI-RS is transmitted in one CSI measurement, i.e. in one measurement window, the base station transmits only one CSI-RS resource to the terminal for CSI measurement, and the one CSI-RS corresponds to the whole port. Because the codebook in the existing standard only supports CSI measurement of 32 antenna ports at most, the one CSI-RS can only be used to evaluate the channel state of 32 antenna ports at most. However, with the increase of the number of base station antennas, CSI measurement of larger ports can provide greater spectral efficiency and system capacity of the downlink. If you want to support CSI measurement of higher port numbers (such as 128 antenna ports), like the AP CSI-RS Doppler measurement in FIG. 3, the base station will transmit multiple CSI-RS resources in one measurement window, and the multiple CSI-RS resources are used to measure the whole large port (such as 128 antenna ports), and each CSI-RS is used to measure part of the whole large port (such as 32 antenna ports). Because in the existing protocol, a single station supports at most one resource for one CSI measurement of at most 32 antenna ports. In order to be compatible with the existing users, the protocol stipulates that the large port is divided into several part ports, and a CSI-RS resource is allocated for each part port to measure the large port. In addition, for AP CSI-RS Doppler measurement, the terminal side also needs to perform multiple channel state measurements on the whole large port.

[0131] Taking 4 times of CSI measurement of 128 ports as an example, the terminal side measures the channel state of 128 antenna ports using 4 CSI-RS resources each time, and each CSI-RS resource is used to measure the channel state of 32 antenna ports. That is, the 128 antenna ports are divided into 4 antenna port groups, and each antenna port group is measured by one CSI-RS resource. As can be seen, for AP CSI-RS Doppler measurement of a large port (such as 128 antenna ports), each channel state measurement of the whole large port is performed by measuring different part antenna ports (part ports correspond to one antenna port group) through multiple CSI-RS resources each time, so the terminal side needs to know the resource used by the one antenna port group in each measurement. That is, if you want to support Doppler measurement of larger antenna port numbers (such as 128 antenna ports), you need to divide the large port into multiple antenna port groups and perform multiple channel state measurements on the multiple antenna port groups, and the terminal needs to know the resource configuration information of each part port in each measurement.

[0132] In addition, the terminal needs a certain processing time to receive channel measurement information and report the corresponding CSI. The existing protocol has specified the processing time for a maximum of 32 ports. Since the terminal needs to measure and process channel state information of more ports, the expansion of terminal processing time is an inevitable trend, so it is necessary to further specify the time from the end of port measurement to the start of CSI report under large ports. Therefore, how to design the resource configuration scheme of AP CSI-RS Doppler measurement for large ports and determine the time from the end of port measurement to the start of CSI report has become a problem to be solved.

[0133] Based on the above problems, the present application provides a communication method, which indicates the resource used by each antenna port group in each measurement through resource configuration information, so that the K resources used by the K antenna port groups in each measurement in M channel state measurements can be determined according to the resource configuration information. Further, the KxM resources for M channel state measurements of the K antenna port groups can be determined, i.e. the resources used by the K antenna port groups in each measurement in the Doppler measurement, so that M channel state measurements of the K antenna port groups are performed. The resource configuration scheme of AP CSI-RS Doppler measurement for larger ports is improved. In addition, the terminal device can also determine that the time from the end of measurement of the K antenna port groups to the start of CSI report is KxZ' ref or the preset maximum time Z max The time is the shorter one, which not only improves the resource configuration scheme of AP CSI-RS Doppler measurement for larger ports, but also determines the time from the end of large port measurement to the start of CSI report.

[0134] It should be noted that the resource (resource) described in the present application is a CSI-RS resource. Exemplarily, the CSI-RS resource can be a time domain resource or a frequency domain resource occupied by the CSI-RS, or a resource block used for transmitting the CSI-RS, etc. At least one CSI-RS resource can be included in a resource set (resource set).

[0135] FIG. 4 is a schematic flow chart of a communication method 400 provided by an embodiment of the present application. As shown in FIG. 4, the method 400 can include the following steps.

[0136] S410, the network device sends resource configuration information to the terminal device, the resource configuration information being used for indicating resources used by each antenna port group in each channel state measurement in M channel state measurements for K antenna port groups, wherein the resources used by a same antenna port group in each channel state measurement are different, and the resources used by any two antenna port groups in a same channel state measurement are different, M≥2, K≥2, and each antenna port group includes at least one antenna port. Correspondingly, the terminal device receives the resource configuration information from the network device.

[0137] Specifically, the resource configuration information is used for indicating resources used by a kth antenna port group in M channel state measurements in a mth measurement, k∈[1, K], m∈[1, M].

[0138] Optionally, the resources used by each antenna port group in each channel state measurement in M channel state measurements for K antenna port groups can be pre-defined by a protocol.

[0139] Exemplarily, taking Doppler measurement with 128 antenna ports as an example. As known from the above, Doppler measurement is a plurality of channel state measurements on a plurality of antenna ports, and one resource supports channel state measurement of at most 32 antenna ports, so 128 antenna ports need to be divided into a plurality of antenna port groups (or a plurality of antenna port groups), each antenna port group including a plurality of antenna ports. Taking K=4 and M=4 as an example, i.e., 128 antenna ports are divided into 4 antenna port groups, each antenna port group including 32 antenna ports, and Doppler measurement of 128 antenna ports needs 4 channel state measurements on the 4 antenna port groups. Through the resources of each antenna port group in the 4 antenna port groups indicated by the resource configuration information, the terminal side can determine 1 resource used by the 4 antenna port groups in each channel state measurement, and further determine 16 resources used by the 4 antenna port groups in 4 measurements, thereby determining the resource configuration information of the 128 antenna ports in Doppler measurement.

[0140] It should be noted that the division manner of dividing a large port into a plurality of partial ports is not limited, for example, the above 128 antenna ports can be divided into 4 antenna port groups, each antenna port group including 32 antenna ports, or can be divided into 8 antenna port groups, each antenna port group including 16 antenna ports, and the like.

[0141] In a possible implementation, the resource configuration information is used to indicate a correspondence between the M channel state measurements and M resource sets, where each resource set includes K resources for one of the M channel state measurements of the K antenna port groups, and the K resources in each resource set are mapped to the K antenna port groups.

[0142] In one approach, the K resources in each resource set are arranged according to an order #1 according to resource IDs, the K antenna port groups are arranged according to an order #2, and the mapping between the K resources in each resource set and the K antenna port groups is that the i th resource in the order #1 corresponds to the i th antenna port in the order #2, i ∈ [1, K]. The order #1 is an example of a first order, and the order #2 is an example of a second order.

[0143] The order #1 is an arrangement of the K resources in each resource set, and the order #2 is an arrangement of the K antenna port groups.

[0144] For example, the order #1 is that the K resources in each resource set are arranged in ascending or descending order according to resource IDs.

[0145] For example, the order #2 includes: in AP CSI-RS Doppler measurement, 128 antenna ports are measured each time, and in each channel state measurement, the 128 antenna ports are divided into 4 antenna port groups, that is, 4 antenna port groups are measured each time. If the port IDs corresponding to the 128 antenna ports are 0-127, the order #2 can be: 0-31 are the first group of antenna ports, 32-63 are the second group of antenna ports, 64-95 are the third group of antenna ports, and 96-127 are the fourth group of antenna ports. Alternatively, the order #2 can also be: 96-127 are the first group of antenna ports, 64-95 are the second group of antenna ports, 32-63 are the third group of antenna ports, and 0-31 are the fourth group of antenna ports.

[0146] It should be noted that, in addition to the above-mentioned arrangement of the order #1 and the order #2, the order #1 and the order #2 can also be other arrangements, for example, the order #1 arranges according to resource IDs, odd numbers first, even numbers last, and odd and even numbers are arranged in ascending or descending order, etc., and the order #2 can also be 0-31 as the second group of ports, 32-63 as the first group of ports, etc., which are not limited in the present application.

[0147] FIG. 5 is a schematic diagram of M resource set configurations for M channel state measurements for 128 antenna ports. As known from above, for AP CSI-RS Doppler measurement for one large port (e.g., 128 antenna ports), the 128 antenna ports need to be divided into multiple antenna port groups for multiple channel state measurements, and the terminal device needs to determine the resources used by the multiple antenna port groups in the multiple channel state measurements. The following takes the example of dividing the 128 antenna ports into 4 antenna port groups in FIG. 5 and performing 4 channel state measurements on the 4 antenna port groups.

[0148] As shown in FIG. 5, for AP CSI-RS Doppler measurement for 128 antenna ports, 4 channel state measurements are needed for the 128 antenna ports, and the 4 channel state measurements are respectively the first measurement, the second measurement, the third measurement, and the fourth measurement shown in FIG. 5. It should be understood that the first measurement to the fourth measurement shown in the figure are for distinguishing the 4 channel state measurements, so as to better illustrate that different resource sets are configured for the 4 measurements, and do not constitute a limitation on the present application. The AP CSI-RS Doppler measurement can also be performed for M channel state measurements, which is not limited.

[0149] When the 128 antenna ports are divided into 32 antenna ports for one group for measurement, then the 128 antenna ports are divided into 4 antenna port groups. For AP CSI-RS Doppler measurement for 128 antenna ports, 4 channel state measurements are needed for the 4 antenna port groups. The network device configures one resource set for each channel state measurement, so for 4 channel state measurements, a total of 4 resource sets are configured, and each resource set includes 4 resources, and each resource is used for one measurement on one antenna port group. It should be understood that for AP CSI-RS Doppler measurement for 128 antenna ports, a total of 16 resources are configured, and each resource is used for one channel state measurement on one antenna port group.

[0150] Each resource set is composed of a group of resources corresponding to 128 antenna ports, and an identifier (ID) of each resource set is used to distinguish different measurements. For example, as shown in FIG. 5, from the time axis, it can be seen that four channel state measurements are respectively performed for 128 antenna ports, and each measurement corresponds to a resource set. Exemplarily, the first measurement corresponds to the first resource set, the second measurement corresponds to the second resource set, the third measurement corresponds to the third resource set, and the fourth measurement corresponds to the fourth resource set. Each resource set includes 4 resources, each resource is used to measure an antenna port group, and there are 4 antenna port groups, each of which includes 32 antenna ports. Therefore, the same antenna port group uses different resources in each channel state measurement, and any two antenna port groups use different resources in the same channel state measurement.

[0151] Exemplarily, as shown in FIG. 5, the first resource set includes resource #0, resource #4, resource #8 and resource #12, and the first resource set corresponds to the first measurement. The second resource set includes resource #1, resource #5, resource #9 and resource #13, and the second resource set corresponds to the second measurement. It can be understood that when 2 channel state measurements are required for 128 antenna ports, the 128 antenna ports are divided into 4 antenna port groups, the first measurement can use the four resources of resource #0, resource #4, resource #8 and resource #12 to measure the 4 antenna port groups, and the second measurement can use the four resources of resource #1, resource #5, resource #9 and resource #13 to measure the 4 antenna port groups.

[0152] Optionally, the network device indicates that the K resources in each resource set in the M resource sets are arranged according to the order #1 according to the resource ID.

[0153] As an example, the resource configuration information is further used to indicate that the K resources in each resource set in the M resource sets are arranged according to the order #1 according to the resource ID.

[0154] Optionally, the arrangement of the K resources in each resource set according to the order #1 according to the resource ID can also be protocol predefined.

[0155] In one mode, the network device indicates that the K antenna port groups are arranged according to the order #2, and optionally, the arrangement of the K antenna port groups according to the order #2 can also be protocol predefined.

[0156] As an example, the resource configuration information is further used to indicate that the K antenna port groups are arranged according to the order #2.

[0157] FIG. 6 is a schematic diagram of the K resources in each resource set arranged in ascending order.

[0158] Exemplarily, as shown in FIG. 6, 2 times of channel state measurements are performed on 128 antenna ports, and the 128 antenna ports are divided into 4 antenna port groups, i.e., 2 times of channel state measurements are performed on 4 antenna port groups, and each time of channel state measurement corresponds to one resource set, and each resource set includes 4 resources. When the 4 resources in each set are configured to be arranged in ascending order according to resource IDs, then for the first measurement, resource #0 corresponds to resource #0 after re-ascending arrangement, resource #4 corresponds to resource #1 after re-ascending arrangement, resource #8 corresponds to resource #2 after re-ascending arrangement, and resource #12 corresponds to resource #3 after re-ascending arrangement. Similarly, on the second measurement, resources #1, #5, #9 and #13 are re-ascending arranged as resources #0, #1, #2 and #3.

[0159] It should be noted that after re-arranging the K resources in each resource set, the identification of the K resources after the arrangement can not be changed, for example, in FIG. 6, resources #1 and #5 are arranged in ascending order, and the identification of the resources can not be changed to resources #0 and #1, but it is indicated that resource #1 is arranged first in the second resource set and resource #5 is arranged second in the second resource set, and the identification of the resources is not changed. Alternatively, the identification of the K resources after the arrangement can also be changed according to the arrangement order, for example, resources #1 and #5 are arranged in ascending order, and the identification of the resources is changed to resources #0 and #1. The present application does not limit this.

[0160] In one way, in M times of channel state measurements, the measurement start time between each resource in each time of channel state measurement is the same.

[0161] Exemplarily, when 4 resource sets are configured, each resource set is used to perform one time of channel state measurement on 4 antenna port groups, and the time when each resource in each resource set starts measurement is consistent. It can be understood that in each measurement, the measurement on 128 antenna ports is performed in a way that the 128 antenna ports are divided into 4 antenna port groups, so the 4 antenna port groups need to start measurement at the same time, i.e., the time when each antenna port group starts measurement using resources is consistent, for example, resources #0, #4, #8 and #12 start to measure 4 antenna port groups at the same time. However, it should be understood that in each measurement, when one time of measurement occupies one time slot, the start symbol of the 4 resources can be different, and the length of the occupied symbol can also be different. In the figure, only for example, the symbol occupied by the 4 resources in the time domain and the start symbol position can be different.

[0162] Alternatively, in each time of channel state measurement, the measurement start time between each resource can be different.

[0163] In one mode, the time interval between the end time of the ith channel state measurement and the start time of the (i+1)th channel state measurement is the same; or, the end time of the ith channel state measurement is the same as the start time of the (i+1)th channel state measurement, i∈[1,M].

[0164] In one mode, the time interval between the end time of the ith channel state measurement and the start time of the (i+1)th channel state measurement is different; or, the end time of the ith channel state measurement is different from the start time of the (i+1)th channel state measurement, i∈[1,M].

[0165] For example, the time interval between the first measurement and the start of the second measurement can be the same as or different from the time interval between the second measurement and the start of the third measurement.

[0166] For example, the end time of the first measurement can be the same as the start time of the second measurement, i.e., the first measurement and the second measurement can be performed continuously; in addition, the end time of the first measurement can also be different from the start time of the second measurement, i.e., the first measurement and the second measurement can also be performed discontinuously.

[0167] It should be noted that, for example, the first measurement and the second measurement can be performed continuously, i.e., the time interval between the first measurement and the second measurement is 0, while the second measurement and the third measurement can be performed with an interval, i.e., the first measurement and the second measurement have a time interval; or, the second measurement and the third measurement can also be performed continuously, i.e., the time interval between the second measurement and the third measurement is 0. That is, the time interval between the adjacent two measurements and whether the adjacent two measurements are continuous are not limited in the present application.

[0168] In one mode, the time domain location of the resource is the same as that of the resource, and the frequency domain location is different; or, the frequency domain location of the resource is the same as that of the resource, and the time domain location is different; or, the time-frequency location of the resource is different from that of the resource. The configuration of the resource includes but is not limited to: code division multiplexing (CDM) type, power offset, density, transmission configuration indicator (TCI) state, etc.

[0169] It should be noted that the M channel state measurements correspond to M time units respectively, one channel state measurement corresponds to one time unit, and different time units are used to distinguish different channel state measurements. For example, the M channel state measurements correspond to M measurement time slot indexes respectively, one channel state measurement corresponds to one measurement time slot, the first measurement can correspond to measurement time slot #0, the second measurement corresponds to measurement time slot #1, the third measurement corresponds to measurement time slot #2, the fourth measurement corresponds to measurement time slot #3, and so on. Therefore, each resource set can also be understood as corresponding to one time unit, which can be a measurement time slot, a measurement time, and the like, without limitation.

[0170] In a possible implementation, the resource configuration information is used to indicate K×M resources, the K×M resources correspond to one resource set, and the K×M resources are used for M channel state measurements of K antenna port groups. The K×M resources are divided into K resource groups according to a first rule, the K resource groups correspond to the K antenna port groups respectively, each resource group includes M resources, and the M resources correspond to the M channel state measurements respectively.

[0171] In a possible implementation, the resource configuration information is used to indicate a correspondence between K resources corresponding to each of M channel state measurements and K antenna port groups, K×M resources corresponding to the M channel state measurements correspond to one resource set, and the K×M resources are used for M channel state measurements of the K antenna port groups. Alternatively, the resource configuration information is used to indicate a correspondence between M resources corresponding to each of K antenna port groups and M channel state measurements, K×M resources corresponding to the K antenna port groups correspond to one resource set, and the K×M resources are used for M channel state measurements of the K antenna port groups.

[0172] In one manner, the resource configuration information is used to indicate a correspondence between K resources corresponding to each of M channel state measurements and K antenna port groups, and the resource configuration information is also used to indicate the K resources corresponding to each of the M resource groups.

[0173] Specifically, the K resources corresponding to each of the channel state measurements are K resources arranged according to the order #3 indicated by the network device and / or predefined by a protocol, and the K antenna port groups are arranged according to the order #2, so that the correspondence between the K resources corresponding to each of the channel state measurements and the K antenna port groups is that the i th resource in the order #3 corresponds to the i th antenna port group in the order #2, i∈[1,K].

[0174] Optionally, the K×M resources can belong to one resource set. Therefore, the resource configuration information can also be used for the K×M resources.

[0175] In one manner, the KxM resources are divided into K resource groups according to a first rule, including: each resource in the KxM resources corresponds to one channel state measurement of at least one antenna port group in M channel state measurements, the KxM resources are divided into M resource groups, each resource group includes K resources, each resource group corresponds to one channel state measurement, and the K resources in each resource group are arranged according to sequence #3, then the kth resource group in the K resource groups includes the kth resource arranged according to sequence #3 in each resource group, k∈[1,K]. Sequence #3 is an example of the sixth sequence.

[0176] It should be understood that the resource group and the resource group described in the present application represent that a plurality of resources belong to a group, and the plurality of resources belonging to a group can also be referred to as a resource class or a resource cluster, that is, a plurality of resources belong to a class or a cluster, which is not limited in the present application.

[0177] Optionally, the network device indicates that the K resources in each resource group are arranged according to sequence #3 according to the resource ID.

[0178] As an example, the resource configuration information is also used to indicate that the K resources in each resource group are arranged according to sequence #3 according to the resource ID.

[0179] Optionally, the arrangement of the K resources in each resource group according to sequence #3 according to the resource ID can also be protocol predefined.

[0180] For example, sequence #3 can be ascending or descending arrangement of the K resources in each resource group.

[0181] FIG. 7 is a schematic diagram of resource set configuration for 4 channel state measurements of 128 antenna ports. The following takes the example of dividing 128 antenna ports into 4 antenna port groups in FIG. 7 and performing 4 channel state measurements on the 4 antenna port groups.

[0182] For example, as shown in FIG. 7, for AP CSI-RS Doppler measurement of 128 antenna ports, 128 antenna ports are divided into 4 antenna port groups, which need to perform 4 channel state measurements. The network device configures a resource set, which is composed of 16 resources corresponding to 4 channel state measurements of 4 antenna port groups, that is, resource #0 to resource #15 shown in FIG. 7.

[0183] As shown in FIG. 7, for the AP CSI-RS Doppler measurement of 128 antenna ports, 4 channel state measurements are needed for the 128 antenna ports, and the 4 channel state measurements are respectively the first measurement, the second measurement, the third measurement and the fourth measurement shown in the figure. It should be understood that the first measurement to the fourth measurement shown in the figure are for distinguishing the 4 channel state measurements, so as to better illustrate that the 4 measurements are configured with different resource sets, and do not constitute limitation to the present application. The AP CSI-RS Doppler measurement can also be performed for M channel state measurements, which is not limited.

[0184] When the 128 antenna ports are divided into 32 antenna ports for measurement, the 128 antenna ports are divided into 4 antenna port groups. For the AP CSI-RS Doppler measurement of 128 antenna ports, 4 channel state measurements are needed for the 4 antenna port groups. Since the 4 antenna port groups perform 4 measurements, a total of 16 resources are needed. Therefore, the network device configures a resource set for the 4 channel state measurements, and the resource set includes 16 resources, and each resource is used for performing a measurement on an antenna port group.

[0185] It should be understood that FIG. 7 exemplarily shows that when K=4 and M=4, that is, the 128 antenna ports are divided into 4 antenna port groups, and 4 channel state measurements are performed, 16 resources are configured. The 16 resources belong to a resource set. The following takes FIG. 8 as an example to illustrate the configuration scheme that K×M resources are divided into K resource groups, the K resource groups correspond to K antenna port groups one by one, and M resources in the K resource groups correspond to M channel state measurements one by one.

[0186] FIG. 8 is a schematic diagram of an ascending arrangement of K×M resources in a resource set.

[0187] Exemplarily, as shown in FIG. 8, 2 times of channel state measurement are performed on 128 antenna ports, and the 128 antenna ports are divided into 4 antenna port groups, i.e., 2 times of channel state measurement are performed on 4 antenna port groups. Therefore, one resource set before sorting includes 8 resources, i.e., resource #0, resource #1, resource #4, resource #5, resource #8, resource #9, resource #12 and resource #13. The terminal side has the capability of distinguishing different times of measurement, and can determine that resource #0, resource #4, resource #8 and resource #12 correspond to the first time of measurement, and resource #1, resource #5, resource #9 and resource #13 correspond to the second time of measurement. The 4 resources in each time of measurement are indicated or pre-defined according to the ascending order of resource ID, and therefore the 4 resources in each time of measurement are arranged in ascending order. That is, as shown in FIG. 8, after the 4 resources in the first time of measurement are arranged in ascending order, resource #0 corresponds to resource #0, resource #4 corresponds to resource #1, resource #8 corresponds to resource #2, and resource #12 corresponds to resource #3; and after the 4 resources in the second time of measurement are arranged in ascending order, resource #1 corresponds to resource #0, resource #5 corresponds to resource #1, resource #9 corresponds to resource #2, and resource #13 corresponds to resource #3.

[0188] It should be noted that after the K resources in each time of measurement are reordered, the identification of the K sorted resources can not be changed, for example, in FIG. 8, after resource #1 and resource #5 are arranged in ascending order, resource #1 and resource #5 can not be changed to resource #0 and resource #1, but resource #1 is arranged first in the second time of measurement and resource #5 is arranged second in the second time of measurement, and the identification of the resources is not changed. Alternatively, the identification of the K sorted resources can also be changed according to the order of arrangement, for example, after resource #1 and resource #5 are arranged in ascending order, the identification of the resources is changed to resource #0 and resource #1. The present application does not limit this.

[0189] For example, each resource in FIG. 8 is used to perform one channel state measurement on one antenna port group, so the two measurements on the same antenna port group can be classified as a group, that is, one resource group corresponds to one antenna port group, and each resource in one resource group corresponds to one measurement. For example, the first resource #0 and the second resource #1 in the first measurement and the second measurement are classified as a first resource group, the third resource #8 and the fourth resource #9 are classified as a second resource group, the fifth resource #12 and the sixth resource #13 are classified as a third resource group, and the seventh resource #16 and the eighth resource #17 are classified as a fourth resource group. One resource group corresponds to one antenna port group, so if the first resource group corresponds to a first antenna port group, the first resource #0 in the first resource group is used to perform the first measurement on the first antenna port group, and the second resource #1 in the first resource group is used to perform the second measurement on the first antenna port group. Similarly, if the second resource group corresponds to a second antenna port group, the third resource #8 in the second resource group is used to perform the first measurement on the second antenna port group, and the fourth resource #9 in the second resource group is used to perform the second measurement on the second antenna port group.

[0190] It should be understood that the first antenna port group and the second antenna port group are for facilitating the description that the two resources in one resource group correspond to the same antenna port group, and do not limit the application. For example, the first resource group can correspond to the second antenna port group, and the like.

[0191] In a possible implementation, the resource configuration information is used for K×M resources, the K×M resources correspond to one resource set, the K×M resources are used for M times of channel state measurements on K antenna port groups, the K×M resources are divided into M resource groups according to a second rule, the M resource groups correspond to the M times of channel measurements one by one, and each resource group includes K resources. The K resources in each resource set correspond to the K antenna port groups one by one.

[0192] In one manner, the resource configuration information is used for the K resources corresponding to each resource group.

[0193] In one manner, the K×M resources are divided into M resource groups according to the second rule, including: the K×M resources are arranged according to the sequence #4, and then the (nK+1)th resource to the (nK+K)th resource in the sequence #4 are divided into the nth resource group in the M resource groups, n∈[0, M-1]. The sequence #4 is an example of the third sequence.

[0194] Optionally, the network device indicates that the K×M resources are arranged according to the sequence #4 according to the resource ID.

[0195] As an example, the resource configuration information is further used to indicate that the K×M resources are arranged according to the sequence #4 according to the resource ID.

[0196] Optionally, the K x M resources arranged in the order #4 according to the resource ID can also be predefined by the protocol.

[0197] Exemplarily, the order #4 is ascending or descending arrangement of the K x M resources.

[0198] The following takes FIG. 9 as an example to illustrate the configuration scheme that the K x M resources are divided into M resource groups, the M resource groups correspond to M times of channel state measurement one by one, and the K resources in the M resource groups correspond to K antenna port groups one by one.

[0199] FIG. 9 is a schematic diagram of another ascending arrangement of K x M resources in a resource set.

[0200] Exemplarily, as shown in FIG. 9, for 2 times of channel state measurement of 128 antenna ports, the 128 antenna ports are divided into 4 antenna port groups, that is, 2 times of channel state measurement are performed on the 4 antenna port groups. Therefore, one resource set before sorting includes 8 resources, which are resource #0, resource #1, resource #4, resource #5, resource #8, resource #9, resource #12, and resource #13. The 8 resources are indicated or predefined by the protocol to be arranged in ascending order according to the resource ID, so that 8 arranged resources in ascending order are obtained. The arranged resources in ascending order are divided into 2 groups, and 4 resources form one group, that is, the first four arranged resources form the first resource group, that is, the first resource group includes resource #0, resource #1, resource #4, and resource #5. The fifth to eighth arranged resources form the second resource group, that is, the second resource group includes resource #8, resource #9, resource #12, and resource #13. The 4 resources in each resource group are used to perform one time of channel state measurement on the 4 antenna port groups. For example, in FIG. 9, after the resource #0, resource #1, resource #4, resource #5, resource #8, resource #9, resource #12, and resource #13 are arranged in ascending order, the resource #0 corresponds to resource #0, the resource #1 corresponds to resource #1, the resource #4 corresponds to resource #2, the resource #5 corresponds to resource #3, the resource #8 corresponds to resource #4, the resource #9 corresponds to resource #5, the resource #12 corresponds to resource #6, and the resource #13 corresponds to resource #7.

[0201] It should be noted that after the K*M resources are reordered, the identity of the reordered K*M resources can not be changed, for example, after the resources #1 and #4 are arranged in ascending order in FIG. 9, the identity of the resources can not be changed to resources #1 and #2, but it is indicated that the resource #1 is arranged in the second place among the 8 resources and the resource #4 is arranged in the third place among the 8 resources, and the identity of the resources is not changed. Alternatively, the identity of the reordered K*M resources can also be changed according to the arrangement order, for example, after the resources #1 and #4 are arranged in ascending order, the identity of the resources is changed to resources #1 and #2. The present application does not limit this.

[0202] In one way, in the M channel state measurements, the measurement start time between each resource in each channel state measurement is the same.

[0203] Exemplarily, when 1 resource set is configured, the 1 resource set includes 16 resources, and the 16 resources are used for 4 channel state measurements on 4 antenna port groups, the time when the 4 resources start measurement in each channel state measurement remains consistent. It can be understood that in each measurement, for the measurement of 128 antenna ports, since the measurement is performed in the manner of dividing the 128 antenna ports into 4 antenna port groups for measurement, the 4 antenna port groups need to start measurement at the same time, that is, the time when the resources used by each antenna port group start measurement in each measurement is consistent, for example, the resources #0, #4, #8 and #12 start measurement of the 4 antenna port groups at the same time. However, it should be understood that in each measurement, when one measurement occupies one time slot, the start symbols of the 4 resources can be different, and the symbol lengths occupied can also be different. In the figure, only for example, the symbols occupied in the time domain and the start symbol positions of the 4 resources can be different.

[0204] In one way, the time interval between the end time of the i th channel state measurement and the start time of the i+1 th channel state measurement is the same; or the end time of the i th channel state measurement is the same as the start time of the i+1 th channel state measurement, i∈[1,M].

[0205] In one way, the time interval between the end time of the i th channel state measurement and the start time of the i+1 th channel state measurement is different; or the end time of the i th channel state measurement is different from the start time of the i+1 th channel state measurement, i∈[1,M].

[0206] In one manner, the resources have the same time domain location and different frequency domain locations, or the resources have the same frequency domain location and different time domain locations, or the resources have different time domain locations and different frequency domain locations. The configuration of the resources includes, but is not limited to, code division multiplexing (CDM) type, power offset, density, transmission configuration indicator (TCI) state, and the like.

[0207] It should be noted that in addition to the above-mentioned sequence #3 and sequence #4, the sequence #3 and sequence #4 can also be other sorting manners, for example, the sequence #3 or sequence #4 can be arranged according to the resource ID, with odd numbers first and even numbers last, and the odd and even numbers are arranged in ascending order or descending order, and the like, which is not limited in the present application.

[0208] In one possible implementation, the resource configuration information is used to indicate the correspondence between the K antenna port groups and the K resource sets, wherein each resource set includes M resources, and the M resources in each resource set have a mapping relationship with M channel state measurements.

[0209] In one manner, the M resources are arranged according to sequence #5 according to the identification of the resources, and the M channel state measurements are arranged according to sequence #6, and the mapping relationship between the M resources in each resource set and the M channel state measurements is that the i-th resource in sequence #5 corresponds to the i-th channel state measurement in sequence #6, i∈[1,M]. Sequence #5 is an example of the fourth sequence, and sequence #6 is an example of the fifth sequence.

[0210] Wherein, sequence #5 is the sorting manner of the M resources in each resource set, and sequence #6 is the sorting manner of the M channel state measurements.

[0211] For example, sequence #5 is the ascending or descending arrangement of the M resources.

[0212] For example, sequence #6 is the ascending arrangement of the M channel state measurements according to the measurement time slot index corresponding to each measurement. Sequence #6 includes: in Doppler measurement, the M channel state measurements correspond to the M measurement time slot indexes one by one, and are arranged in ascending order according to the M measurement time slot indexes, for example, the first measurement can correspond to measurement time slot #0, the second measurement corresponds to measurement time slot #1, the third measurement corresponds to measurement time slot #2, and the fourth measurement corresponds to measurement time slot #3.

[0213] It should be noted that in addition to the above-mentioned sequence #5 and sequence #6, the sequence #5 and sequence #6 can also be other sorting manners, for example, the sequence #5 is sorted according to the resource ID, and the odd number is in front, the even number is in back, and the odd and even numbers are sorted in ascending order or descending order, etc., and the sequence #6 can also be that the first measurement corresponds to the first measurement moment, the second measurement corresponds to the second measurement moment, etc., which is not limited in the present application.

[0214] FIG. 10 is a schematic diagram of K resource set configurations for M times of channel state measurement for 128 antenna ports. As known from the above, for AP CSI-RS Doppler measurement of one large port (for example, 128 antenna ports), the 128 antenna ports need to be divided into multiple antenna port groups for multiple times of channel state measurement, and the terminal device needs to determine the resources used by the multiple antenna port groups in the multiple times of channel state measurement. The following takes the example of dividing the 128 antenna ports into 4 antenna port groups in FIG. 10 and performing 4 times of channel state measurement on the 4 antenna port groups.

[0215] As shown in FIG. 10, for AP CSI-RS Doppler measurement of 128 antenna ports, 4 times of channel state measurement need to be performed on the 128 antenna ports, and the 4 times of channel state measurement are respectively the first measurement, the second measurement, the third measurement, and the fourth measurement shown in FIG. 10. It should be understood that the first measurement to the fourth measurement shown in the figure are for distinguishing the 4 times of channel state measurement, so as to better illustrate that different resource sets are configured for the 4 times of measurement, which does not constitute a limitation of the present application.

[0216] When the 128 antenna ports are divided into 32 antenna ports for one group for measurement, the 128 antenna ports are divided into 4 antenna port groups. For AP CSI-RS Doppler measurement of 128 antenna ports, 4 times of channel state measurement need to be performed on the 4 antenna port groups. The network device configures one resource set for each antenna port group that needs to perform 4 times of measurement, so for the 4 antenna port groups, a total of 4 resource sets are configured, each resource set includes 4 resources, and each resource is used for performing one measurement on one antenna port group. It should be understood that for AP CSI-RS Doppler measurement of 128 antenna ports, a total of 16 resources are configured, each resource is used for one antenna port group to perform one time of channel state measurement, and the 4 resources in one resource set are used for 4 times of measurement on the same antenna port group.

[0217] Each resource set is composed of a group of resources corresponding to one antenna port group, and the group of resources includes M resources, which are used for M times of channel state measurement on the same antenna port group. For example, as shown in FIG. 10, a black box represents a resource set, and each resource set is configured to correspond to one antenna port group. In addition, it can be seen from the time axis that four times of channel state measurement are performed on 128 antenna ports respectively, and therefore 4 resources in one resource set are used for 4 times of channel state measurement on the same antenna port group. Exemplarily, the first antenna port group corresponds to the first resource set, the second antenna port group corresponds to the second resource set, the third antenna port group corresponds to the third resource set, and the fourth antenna port group corresponds to the fourth resource set. Each resource set includes 4 resources, each resource is used for measuring the same antenna port group, and each antenna port group includes 32 antenna ports, and therefore 4 resources are used for measuring the same antenna port group 4 times. Therefore, the same antenna port group uses different resources in each channel state measurement, and any two antenna port groups use different resources in the same channel state measurement.

[0218] It should be noted that the first antenna port group to the fourth antenna port group are examples of dividing 128 antenna ports into four groups, and the 32 antenna ports in each antenna port group are not limited, for example, the 128 antenna ports correspond to identifiers 0-127, the first antenna port group can include antenna ports 0-31, or can include antenna ports 32-63, or can include antenna ports 64-95, and in addition, the 32 antenna ports in the first antenna port group can also be 32 antenna ports with any antenna port identifier, which is not limited in the present application.

[0219] Exemplarily, as shown in FIG. 10, the first resource set corresponds to the first antenna port group, and the first resource set includes resource #0, resource #1, resource #2, and resource #3, each resource in the first set corresponds to one measurement. The second resource set corresponds to the second antenna port group, and the second resource set includes resource #4, resource #5, resource #6, and resource #7, each resource in the second set corresponds to one measurement. The third resource set corresponds to the third antenna port group, and the third resource set includes resource #8, resource #9, resource #10, and resource #11, each resource in the third set corresponds to one measurement. The fourth resource set corresponds to the fourth antenna port group, and the fourth resource set includes resource #12, resource #13, resource #14, and resource #15, each resource in the fourth set corresponds to one measurement.

[0220] Optionally, the network device indicates that the M resources in each resource set in the K resource sets are arranged in order #5 according to the resource ID.

[0221] As an example, the resource configuration information is further used to indicate that the M resources in each of the K resource sets are arranged in the order #5 according to the resource ID.

[0222] Optionally, the M resources in each of the resource sets arranged in the order #5 according to the resource ID can also be protocol predefined.

[0223] In one mode, the network device indicates that the M channel state measurements are arranged in the order #6 according to the measurement time, or the M channel state measurements arranged in the order #6 according to the measurement time can also be protocol predefined. The measurement time can be different times of measurement according to the measurement time slot, or different times of measurement according to the measurement time. The time unit represented by the measurement time can be indicated or protocol predefined.

[0224] As an example, the resource configuration information is further used to indicate that the M channel state measurements are arranged in the order #6 according to the measurement time.

[0225] FIG. 11 is a schematic diagram of the M resources in each resource set arranged in ascending order.

[0226] Exemplarily, as shown in FIG. 11, 2 channel state measurements are performed on 128 antenna ports, and the 128 antenna ports are divided into 4 antenna port groups, i.e. 2 channel state measurements are performed on 4 antenna port groups, each antenna port group corresponds to a resource set, and each resource set includes 4 resources. When the 4 resources in each set are configured to be arranged in ascending order according to the resource ID, for the first resource set, resource #0 corresponds to resource #0 after re-ascending sorting, and resource #1 corresponds to resource #1 after re-ascending sorting. Similarly, for the second resource set, resource #4 corresponds to resource #0 after re-ascending sorting, and resource #5 corresponds to resource #1 after re-ascending sorting. For the third resource set, resource #8 corresponds to resource #0 after re-ascending sorting, and resource #9 corresponds to resource #1 after re-ascending sorting. For the fourth resource set, resource #12 corresponds to resource #0 after re-ascending sorting, and resource #13 corresponds to resource #1 after re-ascending sorting.

[0227] It should be noted that after reordering the M resources in each resource set, the identifiers of the reordered M resources can not change, for example, resource #4 and resource #5 in the second resource set in FIG. 11 can not be changed to resource #0 and resource #1 after ascending arrangement, but resource #4 is arranged first in the second resource set and resource #5 is arranged second in the second resource set, and the identifier of the resource is not changed. Alternatively, the identifier of the reordered M resources can also be changed according to the arrangement order, for example, resource #4 and resource #5 are changed to resource #0 and resource #1 after ascending arrangement. The present application does not limit this.

[0228] In one way, the mapping relationship between the M resources in each resource set and the M channel state measurements is one-to-one correspondence between the M resources and the M channel state measurements.

[0229] In one way, the network device indicates that the K resources in each channel state measurement are arranged according to the seventh order according to the resource ID.

[0230] As an example, the resource configuration information is also used to arrange the K resources in each channel state measurement according to the seventh order according to the resource ID.

[0231] Alternatively, the arrangement of the K resources in each channel state measurement according to the resource ID according to the seventh order can also be protocol predefined.

[0232] Exemplarily, the seventh order is ascending or descending arrangement of the K resources in each channel state measurement.

[0233] FIG. 12 is a schematic diagram of ascending arrangement of the K resources in each channel state measurement.

[0234] Exemplarily, as shown in FIG. 12, 2 times of channel state measurements are performed on 128 antenna ports, and the 128 antenna ports are divided into 4 antenna port groups, i.e., 2 times of channel state measurements are performed on 4 antenna port groups, each antenna port group corresponds to a resource set, and each resource set includes 4 resources. The terminal side has the capability of distinguishing different times of measurements, and can determine that resource #0, resource #4, resource #8 and resource #12 correspond to the first time of measurement, and resource #1, resource #5, resource #9 and resource #13 correspond to the second time of measurement. The 4 resources in each time of measurement are indicated or pre-defined according to the resource ID in ascending order. On the first time of measurement, resource #0 corresponds to resource #0 after reordering in ascending order, resource #4 corresponds to resource #1 after reordering in ascending order, resource #8 corresponds to resource #2 after reordering in ascending order, and resource #12 corresponds to resource #3 after reordering in ascending order. Similarly, on the second time of measurement, resource #1, resource #5, resource #9 and resource #13 correspond to resource #0, resource #1, resource #2 and resource #3 respectively after reordering in ascending order. The first resource set corresponds to the first antenna port group, and the first resource includes resource #0 and resource #1. The second resource set corresponds to the second antenna port group, and the second resource includes resource #4 and resource #5. The third resource set corresponds to the third antenna port group, and the third resource includes resource #8 and resource #9. The fourth resource set corresponds to the fourth antenna port group, and the fourth resource includes resource #12 and resource #13.

[0235] It should be noted that after reordering the K resources in each time of channel state measurement, the identification of the reordered K resources can not be changed. For example, in FIG. 12, resource #0 and resource #4 in the second resource set can not be changed to resource #0 and resource #1 after reordering in ascending order, but resource #0 is arranged first in the first time of measurement, and resource #4 is arranged second in the first time of measurement, and the identification of the resources is not changed. Alternatively, the identification of the reordered K resources can be changed according to the order of arrangement. For example, the identification of resource #0 and resource #4 is changed to resource #0 and resource #1 after reordering in ascending order. The present application does not make any limitation in this regard.

[0236] In one mode, in M times of channel state measurements, the measurement start time between each resource in each time of channel state measurement is the same.

[0237] Alternatively, in each time of channel state measurement, the measurement start time between each resource is different.

[0238] In one mode, the time interval between the end time of the i th time of channel state measurement and the start time of the i+1 th time of channel state measurement is the same; or the end time of the i th time of channel state measurement is the same as the start time of the i+1 th time of channel state measurement, i∈[1,M].

[0239] In one manner, a time interval between an end time of the ith channel state measurement and a start time of the (i+1)th channel state measurement is different; or, the end time of the ith channel state measurement is different from the start time of the (i+1)th channel state measurement, i ∈ [1, M].

[0240] For example, a time interval from the start of the first measurement to the start of the second measurement can be the same as or different from a time interval from the start of the second measurement to the start of the third measurement.

[0241] For example, the end time of the first measurement can be the same as the start time of the second measurement, i.e., the first measurement and the second measurement can be performed continuously; in addition, the end time of the first measurement can also be different from the start time of the second measurement, i.e., the first measurement and the second measurement can also be performed discontinuously.

[0242] In one manner, the resources have the same time domain location and different frequency domain locations, or the resources have the same frequency domain location and different time domain locations, or the resources have different time domain locations and different frequency domain locations. The configuration of the resources includes but is not limited to code division multiplexing (CDM) type, power offset, density, transmission configuration indicator (TCI) state, and the like.

[0243] It should be noted that the multiple resources shown above are only examples to represent multiple different resources, and the IDs of the multiple resources can be the sequential identifiers shown in the above figures or multiple arbitrary resource identifiers, which are not limited. In addition, the arrangement manner of the multiple resources in the figures is only for better illustrating the resource configuration method used by each antenna port group in each channel state measurement, and does not limit the present application.

[0244] It should be further noted that the ordering manners of the above-mentioned order #1 to the seventh order can be the same or different, for example, the order #1 can be arranged in ascending order, the order #3 can also be arranged in ascending order, or the order #3 is arranged in descending order, and the like, which are not limited by the present application.

[0245] S430, the terminal device performs M channel state measurements on the K antenna port groups according to the resource configuration information.

[0246] As an example, when the resource configuration information is used to indicate the correspondence between M times of channel state measurement and M resource sets, the terminal device arranges K resources included in each of the M received resource sets in an order #1 indicated by the network device or pre-defined by a protocol, to obtain K sorted resources; the K sorted resource IDs and K antenna port groups have a mapping relationship, and if the network device indicates or the protocol pre-defines that the K antenna port groups are arranged in an order #2, the mapping relationship is embodied as p m = p m -KNt. Wherein, m is a resource ID, p m is a mapping rule that the mth resource in the KXM resources corresponds to the mth antenna port group, N is the number of ports included in the K antenna port groups, and t is an index of each time of channel state measurement. The mapping rule that the mth resource in the KXM resources corresponds to the mth antenna port group is embodied as that the M times of channel state measurement correspond to the M resource sets, and the ith resource in the order #1 corresponds to the ith antenna port group in the order #2, i∈[1,K]. Therefore, the terminal device can determine the resource used by each antenna port group in each time of state measurement, and perform M times of channel state measurement on the K antenna port groups according to the determined resource. m m It should be noted that t can be an index of a measurement time unit corresponding to each time of channel state measurement, for example, t is an index of a measurement time slot corresponding to each time of channel state measurement. m m As an example, when the resource configuration information is used to indicate KXM resources, the KXM resources can belong to one resource set. The terminal device can distinguish M times of channel state measurement, and determine K resources corresponding to each time of channel state measurement according to each time of channel state measurement; arrange the K resources in each resource group in an order #3 indicated by the network device or pre-defined by a protocol, and then the K resources in a sorted resource group corresponding to each time of channel state measurement and the K antenna port groups have a mapping relationship. If the network device indicates or the protocol pre-defines that the K antenna port groups are arranged in the order #2, the K sorted resource IDs and the ports have a mapping relationship, and the mapping relationship is embodied as p m = p m -KNt. p m The mapping rule that the mth resource in the KXM resources corresponds to the mth antenna port group is embodied as that each time of channel state measurement corresponds to K resources, and the ith resource arranged in the order #3 corresponds to the ith antenna port group in the order #2, i∈[1,K]. Therefore, the terminal device can determine the resource used by each antenna port group in each time of state measurement, and perform M times of channel state measurement on the K antenna port groups according to the determined resource. q q It should be noted that t can be an index of a measurement time unit corresponding to each time of channel state measurement, for example, t is an index of a measurement time slot corresponding to each time of channel state measurement.

[0249] As an example, when the resource configuration information is used to indicate KXM resources, the KXM resources can belong to one resource set. The terminal device arranges the KXM resources in an order #4 indicated by the network device or predefined by a protocol, and the sorted KXM resources have a mapping relationship with K antenna port groups in each of M channel state measurements. If the network device indicates or the protocol predefines that the K antenna port groups are arranged in an order #2 and the M channel state measurements are arranged in an order #6, the sorted KXM resource IDs corresponding to each of the M channel state measurements have a mapping relationship with the K antenna port groups in each of the M channel state measurements, which is represented as p' m = p m -KNt.p m The mapping rule that the mth resource in the KXM resources corresponds to the mth antenna port group is represented as the n+1th channel state measurement in the order #6 corresponds to the nK+1th resource to the nK+Kth resource in the order #4, and the ith resource in the nK+1th resource to the nK+Kth resource corresponds to the ith antenna port group in the order #2, i ∈ [1, K], n ∈ [0, M-1]. Therefore, the terminal device can determine the resources used by each antenna port group in each channel state measurement, and perform M channel state measurements on the K antenna port groups according to the determined resources.

[0250] As an example, when the resource configuration information is used to indicate the correspondence between the K antenna port groups and the K resource sets, the terminal device arranges M resources included in each of the K resource sets received by the terminal device in an order #5 indicated by the network device or predefined by a protocol, to obtain sorted M resources; the sorted M resource IDs have a mapping relationship with M channel state measurements, and if the network device indicates or the protocol predefines that the M channel state measurements are arranged in an order #6, the mapping relationship is represented as p' q = p q -KNt, where q is an ID of a resource set, p q The mapping rule that the mth resource in the KXM resources corresponds to the mth antenna port group is represented as the mth resource ID, so the resource ID is related to the resource set ID, which is embodied in that the K antenna port groups correspond to the K resource sets, and the M resource IDs in the qth resource set correspond to the qth antenna port group, and the ID of any one of the M resources corresponds to the qth antenna port group, q ∈ [1, K]. p qThe mapping rule that the mth resource in the KxM resources corresponds to the mth antenna port group is that K antenna port groups correspond to K resource sets, and the ith resource in each resource set after being arranged in order #5 corresponds to the ith channel state measurement in order #6, i∈[1,M]. Therefore, the terminal device can determine the resource used by each antenna port group in each channel state measurement, and perform M channel state measurements on the K antenna port groups according to the determined resource.

[0251] As an example, when the resource configuration information is used to indicate the correspondence between the K antenna port groups and the K resource sets, the terminal device can distinguish M channel state measurements, determine the K resources corresponding to each channel state measurement according to each channel state measurement, and arrange the K resources corresponding to each channel state measurement in a seventh order indicated by the network device or predefined by a protocol. Then, the arranged K resources corresponding to each channel state measurement have a mapping relationship with the K antenna port groups. If the network device indicates or the protocol predefines that the K antenna port groups are arranged in order #2, the arranged K resource IDs corresponding to each channel state measurement have a mapping relationship with the ports, and the mapping relationship is p m m m The mapping rule that the mth resource in the KxM resources corresponds to the mth antenna port group is that K antenna port groups correspond to K resource sets, and the ith resource in each resource set after being arranged in order #5 corresponds to the ith channel state measurement in order #6, i∈[1,M]. Therefore, the terminal device can determine the resource used by each antenna port group in each channel state measurement, and perform M channel state measurements on the K antenna port groups according to the determined resource.

[0252] The above describes the resource configuration scheme for M channel state measurements on K antenna port groups and the process of determining the resource used by each antenna port group in each channel state measurement for AP-CSI-RS Doppler measurement. Through the above scheme, the resource configuration method corresponding to one antenna port group (for example, the one antenna port group includes 32 antenna ports) is specified by the base station configuration or the protocol predefinition, so that the terminal side knows the resource corresponding to one antenna port group in the K antenna port groups (for example, the K antenna port groups include 128 antenna ports), and supports AP-CSI-RS Doppler measurement under large ports.

[0253] The method for the terminal to determine the time from the end of large port measurement to the start of reporting CSI report is described below.

[0254] ​​FIG. 13 is a schematic flow chart of a communication method 500 according to an embodiment of the present application. As shown in FIG. 13, the method 500 can include the following steps.

[0255] S510, in a first time period, the terminal device performs channel state measurement on the K antenna port groups; in a second time period, the terminal device reports the CSI report.

[0256] Specifically, in the first time period, the terminal device performs channel state measurement on the K antenna port groups to obtain a first CSI report; the first CSI report includes channel state information of the channel state measurement on the K antenna port groups, K≥2, and each antenna port group includes at least one antenna port; in the second time period, the first CSI report is reported. Wherein, the time from the end of the first time period to the start of the second time period is Z max is a preset maximum time from the end of the first time period to the start of the second time period, Z' ref is predefined by the protocol.

[0257] FIG. 14 is a schematic diagram of the CSI reporting time. As shown in FIG. 14, two time periods are shown in the figure, which are Z ref and Z' ref .

[0258] In the existing protocol, Z ref is defined as the time from the end of the last symbol of the physical downlink control channel (PDCCH) resource triggering the CSI report to the start of the first symbol of the physical uplink shared channel (PUSCH) resource containing the CSI report.

[0259] Z' ref is defined as the time from the end of the last symbol of the latest one of the AP NZP CSI-RS resource for channel measurement and interference measurement and the AP channel state information intermodulation (CSI-IM) resource for interference measurement to the start of the first symbol of the PUSCH resource containing the CSI report.

[0260] In one way, when each antenna port group includes Z antenna ports, then the K antenna port groups include KxZ antenna ports, Z≥1. It can be appreciated that the number of antenna ports is expanded by K times from Z antenna ports to KxZ antenna ports, and since it is only the expansion of the ports, then for the K antenna port groups, the time from the end of the first time period to the beginning of the second time period may be considered as a linear expansion, i.e. wherein, when the third time period measures Z antenna ports, a second CSI report is obtained; when the fourth time period reports the second CSI report, then Z' ref is the interval between the end of the third time period and the beginning of the fourth time period predefined by the protocol.

[0261] Exemplarily, when Z=32, K=4, then the K antenna port groups include 128 antenna ports, and each antenna port group includes 32 antenna ports. The time from the end of the first time period to the beginning of the second time period The linear expansion is wherein, Z' ref is the time predefined by the protocol corresponding to a maximum of 32 antenna ports.

[0262] Specifically, as known from the above, K resources are required for the K antenna port groups to measure, and each antenna port group includes Z antenna ports, so may be expressed as the time from the end of the last symbol in the time domain of the K resource measurement (e.g., PUCCH resource) to the beginning of the first symbol in the time domain of the resource (e.g., PUSCH resource) containing the CSI report, Z' ref is the time from the end of the last symbol in the time domain of the downlink resource (e.g., PUCCH resource) used for Z antenna port measurement to the beginning of the first symbol of the uplink resource (e.g., PUSCH resource) containing the CSI report.

[0263] As an example, when M times of channel state measurement are performed on the K antenna port groups, each antenna port group includes Z antenna ports, the time from the end of the first time period to the beginning of the second time period may be considered as a linear expansion, i.e. wherein, in the first time period, KxM resources are used to perform M times of channel state measurement on the K antenna port groups, and CSI reports of the M times of measurement are obtained, Z≥1. Therefore, the end of the first time period is the end of the M times of measurement. may be expressed as the time from the end of the last symbol in the time domain of the K resource (e.g., PUCCH resource) of the last channel state measurement of the M times of channel state measurement to the beginning of the first symbol in the time domain of the resource (e.g., PUSCH resource) containing the CSI report. Z' refThe time from the end of the last symbol of the downlink resource (e.g., PUCCH resource) for Z antenna port measurement to the start of the first symbol of the uplink resource (e.g., PUSCH resource) containing the CSI report.

[0264] S520, the terminal device sends the CSI report to the network device. Correspondingly, the network device receives the CSI report from the terminal device.

[0265] Specifically, the terminal device sends the CSI report to the network device in the second time period. Correspondingly, the network device receives the CSI report from the terminal device in the second time period.
