Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a resource allocation method, apparatus, device, and storage medium. Background Technology

[0002] Currently, for base station antenna arrays, the coverage of the main lobe can be improved by adding more antenna elements in the vertical dimension. However, this also reduces the vertical beamwidth of the narrow beam. Taking a 32T hybrid digital-analog base station as an example, its antenna has one channel driving eight elements in the vertical dimension, compared to one channel driving six elements in a purely digital base station. This reduces the vertical beamwidth of the narrow beam from approximately 6° to 4.5°, resulting in a smaller beam envelope for the Channel State Information Reference Signal (CSI-RS) resources configured for terminals by the base station. Consequently, this leads to a deterioration in the channel quality measurement performance for edge users. Summary of the Invention

[0066] Figure 9 This is a schematic diagram of the component structure of the terminal according to an embodiment of the present invention. Detailed Implementation

[0067] Before introducing the technical solutions of the embodiments of the present invention, the relevant technologies will be explained first.

[0068] In related technologies, the antenna of a 32T hybrid digital-analog base station has one channel driving eight elements in the vertical dimension, compared to one channel driving six elements in a pure digital base station, which reduces the beamwidth of the narrow beam in the vertical dimension from about 6° to 4.5°.

[0069] Figure 1 This is a schematic diagram of the beam envelope composed of service beams and the beam envelope composed of a set of CSI-RS resources in related technologies, as shown below. Figure 1 As shown, for the service (data) channel, the hybrid digital-analog base station uses a digital phase shifter to perform analog beam scanning in the vertical dimension, which increases the coverage of the service beam in the vertical dimension. However, for a set of CSI-RS resources configured at the cell level, since analog beam scanning in the vertical dimension is not performed, the dynamic range of the beam composed of this set of CSI-RS resources in the vertical dimension (e.g., 9°) is smaller than the dynamic range of the beam composed of the service beam (e.g., 18°).

[0070] In other words, hybrid analog-digital base stations achieve a wider coverage of the data channel through vertical analog beam scanning. However, the CSI-RS beam used for channel state measurement does not perform vertical analog beam scanning. This leads to a mismatch between the dynamic range (envelope) of the CSI-RS beam for channel quality measurement and the dynamic range of the service beam. Specifically, the performance of channel quality measurement deteriorates (referring to users within a 12° range outside the CSI-RS beam envelope), affecting the performance experience of edge users. Consequently, it affects the accuracy of uplink and downlink adaptation and massive MIMO beamforming, thus reducing system performance.

[0071] Based on this, in this embodiment of the invention, a first set of CSI-RS resources and a second set of CSI-RS resources are configured for the terminal; wherein, the first beam envelope composed of the second set of CSI-RS resources is the difference between the second beam envelope composed of service beams and the third beam envelope composed of the first set of CSI-RS resources.

[0072] Figure 2 This is a schematic diagram illustrating the implementation flow of the resource configuration method according to an embodiment of the present invention, applied to network devices, such as... Figure 2 As shown, the method includes step 201:

[0073] Step 201: Configure the terminal with the first set of CSI-RS resources and the second set of CSI-RS resources; wherein, the first beam envelope composed of the second set of CSI-RS resources is the difference between the second beam envelope composed of the service beams and the third beam envelope composed of the first set of CSI-RS resources.

[0074] It is understood that the first beam envelope composed of the second set of CSI-RS resources can refer to the dynamic range of all CSI-RS resources included in the second set of CSI-RS resources; the third beam envelope composed of the first set of CSI-RS resources can refer to the dynamic range of all CSI-RS resources or beams included in the first set of CSI-RS resources.

[0075] It is understood that the network device can configure the first set of CSI-RS resources and the second set of CSI-RS resources for the terminal through Radio Resource Control (RRC) signaling.

[0076] It is understood that the network device may be an exponential-modulus hybrid base station.

[0077] It is understood that the second beam envelope composed of the service beams can characterize the maximum area range that the service beams can cover. The third beam envelope composed of the first set of CSI-RS resources can characterize the area range that the first set of CSI-RS resources can cover, which is smaller than the maximum area range.

[0078] For example, Table 1 is a schematic diagram of the first set of CSI-RS resources and the second set of CSI-RS resources. As shown in Table 1, the first beam envelope composed of the second set of CSI-RS resources is the difference between the second beam envelope composed of the service beams and the third beam envelope composed of the first set of CSI-RS resources.

[0079] Table 1

[0080]

[0081] It should be noted that users outside the third beam envelope formed by the first set of CSI-RS resources can be considered as users at the cell edge. Considering that accurate measurement results cannot be obtained based on the first set of CSI-RS resources when the terminal is at the cell edge, in order to make the measurement results of terminals at the cell edge more accurate, the network device needs to configure a second set of CSI-RS resources for the terminal in addition to configuring the first set of CSI-RS resources.

[0082] In practical applications, the network device can send a set of cell-level CSI-RS resources for channel quality measurement and another set of cell-level CSI-RS resources for beam management or mobility management to the terminal.

[0083] Accordingly, in one embodiment, the first set of CSI-RS resources is at least one CSI-RS at the cell level for channel quality measurement; the second set of CSI-RS resources is at least one CSI-RS at the cell level for beam management or mobility management.

[0084] For example, Table 2 illustrates the first set of CSI-RS resources and the second set of CSI-RS resources. As shown in Table 2, the first set of CSI-RS resources consists of at least one cell-level CSI-RS used for channel quality measurement, including: CSI-RS1, CSI-RS2, CSI-RS3, etc. The second set of CSI-RS resources consists of at least one cell-level CSI-RS used for beam management or mobility management, including: CSI-RS4, CSI-RS5, etc.

[0085] Table 2

[0086]

[0087] It is worth noting that the second set of CSI-RS resources can also be at least one CSI-RS at the cell level for channel quality measurement.

[0088] In one embodiment, each CSI-RS resource in the first set of CSI-RS resources has multiple ports; each CSI-RS resource in the second set of CSI-RS resources has a single port.

[0089] For example, Table 3 illustrates the first set of CSI-RS resources and the second set of CSI-RS resources. As shown in Table 3, the first set of CSI-RS resources consists of at least one cell-level CSI-RS used for channel quality measurement, including: CSI-RS1, CSI-RS2, CSI-RS3, etc.; the ports of CSI-RS1 are port 1 and port 2; the ports of CSI-RS2 are port 3 and port 4; and the ports of CSI-RS3 are port 5 and port 6. The second set of CSI-RS resources consists of at least one cell-level CSI-RS used for beam management or mobility management, including: CSI-RS4, CSI-RS5, etc.; the port of CSI-RS4 is port 7; and the port of CSI-RS5 is port 8.

[0090] Table 3

[0091]

[0092] It should be noted that each CSI-RS resource in the first set of CSI-RS resources has multiple ports, while each CSI-RS resource in the second set of CSI-RS resources has a single port. Thus, when the terminal is at the cell edge, that is, when the terminal is outside the third beam envelope formed by the first set of CSI-RS resources, the single-port CSI-RS resource has a narrow beam, which is more likely to be aimed at the user. As a result, the terminal can obtain measurement results more quickly.

[0093] In practical applications, if the terminal is within the area covered by the third beam envelope formed by the first set of CSI-RS resources, the network device can configure the first set of CSI-RS resources for the terminal. However, if the terminal is not within the area covered by the third beam envelope formed by the first set of CSI-RS resources, in order to make the measurement results of the terminal more accurate, the network device configures both the first set of CSI-RS resources and the second set of CSI-RS resources for the terminal.

[0094] Based on this, in one embodiment, configuring the terminal with the first set of CSI-RS resources and the second set of CSI-RS resources includes:

[0095] When the terminal is not within the area covered by the third beam envelope composed of the first set of CSI-RS resources, the first set of CSI-RS resources and the second set of CSI-RS resources are configured for the terminal.

[0096] It is understood that the network device can predefine and maintain the second set of CSI-RS resources. Thus, when the terminal is not within the area covered by the third beam envelope formed by the first set of CSI-RS resources, both the first set of CSI-RS resources and the second set of CSI-RS resources are configured for the terminal.

[0097] In practical applications, the terminal can send SRS to the network device, and the network device can determine whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources based on the SRS sent by the terminal.

[0098] Based on this, in one embodiment, the method further includes:

[0099] Receive SRS sent by the terminal;

[0100] Based on the SRS, determine whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources.

[0101] Here, determining whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources, based on the SRS, may include:

[0102] Determine the direction of the SRS; determine the location of the terminal based on the direction of the SRS; and determine whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources based on the location of the terminal.

[0103] In one embodiment, the second set of CSI-RS resources corresponds to multiple vertical beams; each layer includes N vertical beams; N is a positive integer greater than 1.

[0104] It is understood that the vertical beam can refer to a beam in the vertical direction.

[0105] For example, Table 4 illustrates the first and second sets of CSI-RS resources. As shown in Table 4, assume that the first set of CSI-RS resources corresponds to two layers of vertical beams, and the second set of CSI-RS resources also corresponds to two layers of vertical beams. The first set of CSI-RS resources can correspond to the middle two layers of vertical beams, and the second set of CSI-RS resources can correspond to the highest and lowest layers of vertical beams. Each layer includes N = 8 vertical beams.

[0106] Table 4

[0107]

[0108] It should be noted that the first set of CSI-RS resources and the second set of CSI-RS resources can each contain multiple layers of vertical beams. That is, the first set of CSI-RS resources corresponds to multiple layers of vertical beams, and the second set of CSI-RS resources corresponds to multiple layers of vertical beams. Assuming there are a total of four layers of vertical beams, the second set of CSI-RS resources can contain the highest layer and the lowest layer of vertical beams, and the first set of CSI-RS resources can contain the second layer and the third layer of vertical beams.

[0109] It is worth noting that the specific number of layers where the first set of CSI-RS resources and the second set of CSI-RS resources are distributed can be determined according to the actual situation.

[0110] In practical applications, the network device can determine the location of the terminal based on the direction of the SRS, determine the specific vertical dimension beam corresponding to the location of the terminal, and then select at least one vertical dimension beam close to the specific vertical dimension beam from the current layer vertical dimension beams where the specific vertical dimension beam is located and send it to the terminal.

[0111] Based on this, in one embodiment, the method further includes:

[0112] The first vertical beam in which the terminal is located is determined from the multi-layer vertical beams corresponding to the second set of CSI-RS resources;

[0113] Select M vertical beams from the N vertical beams contained in the first layer of vertical beams; M is a positive integer greater than 1 and less than N;

[0114] The M vertical beams are used to form a third set of CSI-RS resources;

[0115] Configure the third set of CSI-RS resources to the terminal.

[0116] For example, suppose the second set of CSI-RS resources corresponds to two layers of vertical beams, namely the highest layer and the lowest layer. The highest layer of vertical beams includes eight vertical beams, and the lowest layer includes eight vertical beams. First, the location of the terminal is determined based on the direction of the SRS sent by the terminal. Then, based on the location of the terminal, the specific vertical beam corresponding to that location is determined. Suppose it is the second vertical beam in the highest layer of vertical beams. Then, three vertical beams close to the second vertical beam are selected from the eight vertical beams included in the highest layer of vertical beams, namely the first, third, and fourth vertical beams. These three vertical beams form the third set of CSI-RS resources and are configured for the terminal.

[0117] In practical applications, the terminal can send SRS to the network device, and the network device can determine whether the terminal is in an SRS-restricted scenario based on the SRS sent by the terminal. SRS restriction can mean that the RSRP or SNR of the SRS is less than or equal to a certain threshold.

[0118] Based on this, in one embodiment, determining the first vertical beam containing the terminal from the multi-layer vertical beams corresponding to the second set of CSI-RS resources includes:

[0119] Receive SRS sent by the terminal;

[0120] Determine the signal quality of the SRS;

[0121] When the signal quality of the SRS is less than or equal to the signal quality threshold, the first vertical beam in which the terminal is located is determined from the multi-layer vertical beams corresponding to the second set of CSI-RS resources.

[0122] Here, the signal quality of the SRS may include RSRP or SNR.

[0123] In practical applications, the terminal can perform round-scan measurements on at least one CSI-RS resource in the first set of CSI-RS resources sent by the network device to obtain RI, PMI, and CQI, and report the RI, PMI, and CQI to the network device. At the same time, the terminal also performs round-scan measurements on at least one CSI-RS resource in the second set of CSI-RS resources sent by the network device, determines the ID of the optimal beam from at least one beam based on the measurement results, and reports the ID of the optimal beam to the network device. Thus, before beamforming, the network device can perform channel estimation based on the RI, PMI, and CQI reported by the terminal, and determine the Modulation and Coding Scheme (MCS) allocated to the terminal based on the CQI and RI to configure the uplink transmission rate. Then, beamforming is performed based on the ID of the optimal beam reported by the terminal. That is, the weight of the optimal beam is determined based on the ID of the optimal beam, and then the weight of the optimal beam is used to perform beamforming on control channels such as the Physical Downlink Control Channel (PDCCH) and / or data channels such as the Physical Downlink Shared Channel (PDSCH) to achieve downlink data transmission.

[0124] Based on this, in one embodiment, the method further includes:

[0125] The system receives first information obtained by measuring the first set of CSI-RS resources by the terminal; and receives second information obtained by measuring the second set of CSI-RS resources by the terminal; wherein the first information includes RI, PMI and CQI; and the second information includes the ID of the optimal beam.

[0126] Channel estimation is performed using the first information; and beamforming is performed using the second information.

[0127] It is understood that the terminal also performs round-scan measurement on at least one CSI-RS resource in the second set of CSI-RS resources sent by the network device, determines the beam with the strongest signal strength from at least one beam based on the measurement results, and reports the ID of the beam with the strongest signal strength as the ID of the optimal beam to the network device.

[0128] The embodiments of the present invention have the following advantages:

[0129] (1) On the basis of configuring the first set of CSI-RS resources for the terminal, the second set of CSI-RS resources is configured for the terminal. The beam envelope composed of the first set of CSI-RS resources is compensated by the second set of CSI-RS resources, thereby expanding the coverage of the beam envelope and ensuring the accuracy of channel quality measurement for edge users.

[0130] In other words, with the goal of aligning the CSI-RS beam dynamic range with the service beam dynamic range, a second set of CSI-RS resources is flexibly configured based on the existing cell-level CSI-RS resources used for channel state quality measurement, i.e., the first set of CSI-RS resources. This second set of CSI-RS resources has a beam dynamic range that complements the beam dynamic range of the first set of CSI-RS resources, according to user direction and channel quality.

[0131] (2) The second set of CSI-RS resources is a reference signal configured by the network side for beam management or mobility management. The terminal measures and reports the optimal CSI-RS beam ID to the network side. The network side performs beamforming on the control channel (such as the Physical Downlink Control Channel, PDCCH) and / or the data channel (such as the Physical Downlink Shared Channel, PDSCH) based on the weight of the optimal beam reported by the terminal, thereby achieving accurate channel measurement and beamforming. Since beamforming can be performed based on the channel measurement results, the accuracy of network uplink and downlink adaptation can be improved.

[0132] Figure 3 This is a schematic diagram illustrating the implementation flow of the resource configuration method according to an embodiment of the present invention, applied to a terminal, such as... Figure 3 As shown, the method includes step 301:

[0133] Step 301: Receive the first set of CSI-RS resources and the second set of CSI-RS resources configured by the network device;

[0134] The first beam envelope formed by the second set of CSI-RS resources is the difference between the second beam envelope formed by the service beams and the third beam envelope formed by the first set of CSI-RS resources.

[0135] It is understood that the first beam envelope composed of the second set of CSI-RS resources can refer to the dynamic range of all CSI-RS resources included in the second set of CSI-RS resources; the third beam envelope composed of the first set of CSI-RS resources can refer to the dynamic range of all CSI-RS resources or beams included in the first set of CSI-RS resources.

[0136] It is understood that the network device can configure the first set of CSI-RS resources and the second set of CSI-RS resources for the terminal through RRC signaling.

[0137] It is understood that the second beam envelope composed of the service beams can characterize the maximum area range that the service beams can cover. The third beam envelope composed of the first set of CSI-RS resources can characterize the area range that the first set of CSI-RS resources can cover, which is smaller than the maximum area range.

[0138] In practical applications, the network device can send a set of cell-level CSI-RS resources for channel quality measurement and another set of cell-level CSI-RS resources for beam management or mobility management to the terminal.

[0139] Accordingly, in one embodiment, the first set of CSI-RS resources is at least one CSI-RS at the cell level for channel quality measurement; the second set of CSI-RS resources is at least one CSI-RS at the cell level for beam management or mobility management.

[0140] In one embodiment, each CSI-RS resource in the first set of CSI-RS resources has multiple ports; each CSI-RS resource in the second set of CSI-RS resources has a single port.

[0141] In practical applications, if the terminal is within the area covered by the third beam envelope formed by the first set of CSI-RS resources, the network device can configure the first set of CSI-RS resources for the terminal. However, if the terminal is not within the area covered by the third beam envelope formed by the first set of CSI-RS resources, in order to make the measurement results of the terminal more accurate, the network device configures both the first set of CSI-RS resources and the second set of CSI-RS resources for the terminal.

[0142] Based on this, in one embodiment, the first set of CSI-RS resources and the second set of CSI-RS resources configured by the receiving network device include:

[0143] When the terminal is not within the area covered by the third beam envelope composed of the first set of CSI-RS resources, it receives the first set of CSI-RS resources and the second set of CSI-RS resources configured by the network device.

[0144] In practical applications, the terminal can send SRS to the network device, and the network device can determine whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources based on the SRS sent by the terminal.

[0145] Based on this, in one embodiment, the method further includes:

[0146] Send SRS to the network device;

[0147] The SRS is used by the network device to determine whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources.

[0148] In one embodiment, the second set of CSI-RS resources corresponds to multiple vertical beams; each layer includes N vertical beams; N is a positive integer greater than 1.

[0149] In practical applications, the network device can determine the location of the terminal based on the direction of the SRS, determine the specific vertical dimension beam corresponding to the location of the terminal, and then select at least one vertical dimension beam close to the specific vertical dimension beam from the current layer vertical dimension beams where the specific vertical dimension beam is located and send it to the terminal.

[0150] Based on this, in one embodiment, the method further includes:

[0151] Receive the third set of CSI-RS resources configured by the network device;

[0152] The third set of CSI-RS resources is formed by the network device determining the first layer of vertical beams where the terminal is located from the multi-layer vertical beams corresponding to the second set of CSI-RS resources; selecting M vertical beams from the N vertical beams contained in the first layer of vertical beams; and using the M vertical beams to form the third set of vertical beams; where M is a positive integer greater than 1 and less than N.

[0153] In practical applications, the terminal can send SRS to the network device, and the network device can determine whether the terminal is in an SRS-restricted scenario based on the SRS sent by the terminal. SRS restriction can mean that the RSRP or SNR of the SRS is less than or equal to a certain threshold.

[0154] Based on this, in one embodiment, the method further includes:

[0155] Send SRS to the network device;

[0156] The SRS is used by the network device to determine the signal quality of the SRS; when the signal quality of the SRS is less than or equal to the signal quality threshold, the first vertical beam in which the terminal is located is determined from the multi-layer vertical beams corresponding to the second set of CSI-RS resources.

[0157] In practical applications, the terminal can perform round-scan measurements on at least one CSI-RS resource in the first set of CSI-RS resources sent by the network device to obtain RI, PMI, and CQI, and report the RI, PMI, and CQI to the network device. Simultaneously, the terminal also performs round-scan measurements on at least one CSI-RS resource in the second set of CSI-RS resources sent by the network device, determines the ID of the optimal beam from at least one beam based on the measurement results, and reports the ID of the optimal beam to the network device. Thus, before beamforming, the network device can perform channel estimation based on the RI, PMI, and CQI reported by the terminal, and determine the MCS allocated to the terminal based on the CQI and RI. Then, it performs beamforming based on the ID of the optimal beam reported by the terminal; that is, it determines the weight of the optimal beam based on the ID of the optimal beam, and then uses the weight of the optimal beam to perform beamforming of the control channel PDCCH and / or the data channel PDSCH. Based on this, in one embodiment, the method further includes:

[0158] The terminal sends first information obtained by measuring the first set of CSI-RS resources to the network device; and sends second information obtained by measuring the second set of CSI-RS resources to the network device.

[0159] The first information includes RI, PMI, and CQI; the second information includes the ID of the optimal beam; the first information is used for the network device to perform channel estimation; the second information is used for the network device to perform beamforming.

[0160] The embodiments of the present invention have the following advantages:

[0161] (1) On the basis of configuring the first set of CSI-RS resources for the terminal, the second set of CSI-RS resources is configured for the terminal. The beam envelope composed of the first set of CSI-RS resources is compensated by the second set of CSI-RS resources, thereby expanding the coverage of the beam envelope and ensuring the accuracy of channel quality measurement for edge users.

[0162] In other words, with the goal of aligning the CSI-RS beam dynamic range with the service beam dynamic range, a second set of CSI-RS resources is flexibly configured based on the existing cell-level CSI-RS resources used for channel state quality measurement, i.e., the first set of CSI-RS resources. This second set of CSI-RS resources has a beam dynamic range that complements the beam dynamic range of the first set of CSI-RS resources, according to user direction and channel quality.

[0163] (2) The second set of CSI-RS resources is a reference signal configured by the network side for beam management or mobility management. The terminal measures and reports the optimal CSI-RS beam ID to the network side. The network side performs beamforming of control channels such as PDCCH and / or data channels such as PDSCH based on the weights of the optimal beam reported by the terminal, thereby achieving accurate channel measurement and Massive MIMO beamforming. Since beamforming can be performed based on the results of channel measurement, the accuracy of network uplink and downlink adaptation can also be improved.

[0164] Figure 4 This is a schematic diagram illustrating the specific implementation process of the resource allocation method in this embodiment of the invention, taking a network device as a base station as an example. Figure 4 As shown, the method includes steps 401 to 406:

[0165] Step 401: The base station can predefine and maintain the second set of CSI-RS resources.

[0166] Here, the base station predefines and maintains a set of CSI-RS resources for beam management (L1) / mobility management (L3). Its beam range is the difference between the dynamic range of the service beam and the dynamic range of the first set of cell-level CSI-RS resources, that is, the complement of the dynamic range of the first set of cell-level CSI-RS resources.

[0167] The second set of CSI-RS resources can correspond to two layers of vertical beams, distributed in the highest and lowest layers, with each layer containing multiple (e.g., 8) vertical beams. Each CSI-RS resource in the second set has a single-port port. Each CSI-RS resource in the second set can be time-division transmitted. The second set of CSI-RS resources includes, but is not limited to, time-domain, frequency-domain, and spatial-domain resources configured for the serving cell and neighboring cells. Time-domain resources include transmission period, frames, and symbols; frequency-domain resources include transmission bandwidth and resource blocks; and spatial-domain resources include beam gain.

[0168] Step 402: The terminal sends an SRS to the base station.

[0169] Step 403: The base station receives the SRS sent by the terminal; based on the SRS, it determines whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources; when the terminal is not within the area covered by the third beam envelope composed of the first set of CSI-RS resources, the base station configures the first set of CSI-RS resources and the second set of CSI-RS resources for the terminal through RRC signaling.

[0170] Here, for a hybrid analog-digital base station, the terminal sends an SRS to the base station. The base station determines the location of the terminal based on the direction of the SRS sent by the terminal, and determines whether the terminal is within the area covered by the third beam envelope composed of the first set of CSI-RS resources based on the location of the terminal.

[0171] Figure 5 This is a schematic diagram of the beam envelopes corresponding to the first and second sets of CSI-RS resources, respectively. Figure 5 As shown, the beam dynamic range of the second CSI-RS is the complement of the beam dynamic range of the first cell-level CSI-RS.

[0172] It should be noted that when the signal quality of SRS (such as RSRP / SNR) is below a certain threshold, the base station determines the location of the terminal based on the SRS direction sent by the terminal, and determines the specific vertical beam corresponding to the location of the terminal based on the location of the terminal. Then, it selects at least one vertical beam close to the specific vertical beam from the current layer vertical beams where the specific vertical beam is located and sends it to the terminal.

[0173] Step 404: The terminal measures the first set of CSI-RS resources and the second set of CSI-RS resources sent by the base station to obtain first information and second information; the first information includes rank indicator RI, precoding matrix indicator PMI and channel quality indicator CQI; the second information includes the identifier ID of the optimal beam.

[0174] Step 405: The terminal reports the first information and the second information to the base station.

[0175] Step 406: The base station performs channel estimation based on the first information reported by the terminal; and performs beamforming using the second information.

[0176] Specifically, before beamforming, the base station can perform channel estimation based on the RI, PMI, and CQI reported by the terminal, and determine the MCS assigned to the terminal based on the CQI and RI. Then, it can perform beamforming based on the ID of the optimal beam reported by the terminal. That is, it can determine the weight of the optimal beam based on the ID of the optimal beam, and then use the weight of the optimal beam to perform beamforming of the control channel PDCCH and / or the data channel PDSCH.

[0177] Step 407: The base station transmits air interface data through the physical layer.

[0178] This example has the following advantages:

[0179] (1) When the terminal is at the cell edge, the terminal is configured with a first set of CSI-RS resources and a second set of CSI-RS resources. In this way, the beam envelope composed of the first set of CSI-RS resources is compensated by the second set of CSI-RS resources, thereby expanding the coverage of the beam envelope and ensuring the accuracy of channel quality measurement for edge users.

[0180] (2) In the case of SRS-limited scenarios, since the signal strength is weak, it is usually a single stream. Therefore, using the ID of the optimal beam reported by the terminal directly for single stream beamforming can improve the beamforming accuracy and the performance of edge users.
