In this application, the 5G system is used as an example for explanation.

[0042] In the embodiment of the present application, the base station may be a device that can communicate with a user terminal. The base station may be any device with wireless transceiver functions. Including but not limited to: base station NodeB, evolved base station eNodeB, base station in 5G communication system, base station in future communication system, access node in WiFi system, wireless relay node, wireless backhaul node, etc. The base station may also be a wireless controller in the cloud radio access network (CRAN) scenario; the base station may also be a small station, a transmission node (TRP), etc., which is not limited in the embodiment of the present application. In this application, a 5G base station is used as an example for explanation.

The user terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. The user terminal may also be sometimes referred to as a terminal, an access terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent or a UE device, etc. The embodiments of the present application are not limited.

[0044] The following is a brief introduction to the technical terms involved in the application examples.

[0045] High frequency bands (i.e., millimeter wave communications) with ultra-wide transmission bandwidth have become an important direction for the development of future mobile communications, attracting the attention of academia and industry around the world. In particular, with increasingly congested spectrum resources and a large number of physical network accesses, the advantages of millimeter waves have become increasingly attractive, and many standard organizations, such as IEEE and 3GPP, have begun to carry out corresponding standardization work. For example, in the 3GPP standard group, high frequency band communications will become an important innovation point for compatible wireless access technologies (New Radio Access Technology, New RAT) under 5G due to its significant advantages in large bandwidth.

[0046] During the antenna weight (also known as precoding, beam) training process, the high-band transmitter sends a training reference signal, and the receiver receives the channel and performs channel estimation. Then, the high-band receiver needs to feed back channel state information to the high-band transmitter, so that the transmitter and receiver can find multiple sets of transmitter and receiver antenna weight pairs required for multi-channel data transmission from the optional transmitter and receiver antenna weight pairs, thereby improving the overall spectrum efficiency.

[0047] For a base station, there may be multiple antenna panels, and each antenna panel may generate multiple beams. A similar situation also exists for the UE (especially for above-6GHz UEs, such as millimeter wave communications). Therefore, the core of beam reporting (also known as channel state information feedback) is to provide an optimal combination solution in a mixed analog domain and / or digital domain.

[0048] Figure 1 1 is a schematic diagram of the structure of a hybrid precoding (hybrid analog digital beamforming) transceiver provided by the present application. Figure 1 As shown, the system transmitter and receiver are configured with multiple antenna units and multiple RF links. Among them, each RF link is interconnected with the antenna array unit (partial connection scenarios are not excluded), and each antenna unit has a digital keyed phase shifter. By loading different phase shift amounts on the signals on each antenna unit, the high-frequency band system realizes beamforming on the analog end. Specifically, in a hybrid beamforming transceiver, there are multiple RF signal streams. Each signal stream is loaded with precoded AWV through a digital keyed phase shifter and sent from a multi-antenna unit to a high-frequency band physical propagation channel; at the receiving end, the RF signal streams received by the multi-antenna units are weighted and combined into a single signal stream. After RF demodulation at the receiving end, the receiver finally obtains multiple received signal streams, which are sampled and received by the digital baseband.

[0049] At the same time, the system transmitter and receiver may have multiple panels. In order to better support space division multiplexing and reduce the complexity of hardware implementation, the number of effective beams under each panel is asymmetric with the maximum number of transmit beams that can actually be supported, that is, the number of beams that can be sent at each moment, that is, the number of TXRUs, is much smaller than the number of optional beams.

[0050] When the TRP / UE has multiple antenna groups, each antenna group can generate a corresponding transmit or receive beam. Figure 2 This is a schematic diagram of downlink transmission of multiple antenna groups provided in the present application. For example, the antenna group-1 (also called panel-1) of the TRP and the antenna group-1 of the UE respectively generate transmit and receive beams for serving DL link-1; the antenna group-2 of the TRP and the antenna group-2 of the UE respectively generate transmit and receive beams for serving DL link-2. Furthermore, DL link-1 and DL link-2 can be associated with two different antenna ports respectively, or DL ​​link-1 and DL link-2 can be associated with the same antenna port.

[0051] In order to support the channel state information (CSI) reporting process, the base station needs to configure the channel state information (CSI) feedback related parameters accordingly. First, the non-periodic CSI trigger state configuration mode is discussed, such as Figure 3 As shown. Multiple CSI-RS resources (CSI-RS resource) are combined into a CSI-RS resource group (CSI-RSresource set), and the CSI-RS resource group is associated with a CSI configuration (CSI resourcesetting, also called CSI-RS resource config). One or more CSI resource settings can be associated with a CSI reporting instance (CSI reporting config), wherein, when multiple CSI resourcesettings are associated, the multiple CSI resource settings can be used for channel measurement (channel measurement) or interference measurement (interference measurement), respectively. In the CSI reporting config, it is additionally necessary to provide the QCL state of each non-periodic CSI-RS for the association.

[0052] In addition, the base station can flexibly configure the deviation between the transmit power of the reference signal and the transmit power of the actual data transmission process through parameters. The power deviation parameters include the deviation from PDSCH RE (resource element) to CSI-RS (in Figure 3 In the figure, the power offset (called Pc) of non-zero-power (NZP)-CSI-RS) and the power offset (PSS) from NZP CSI-RS RE to SSS (Secondary Synchronization Signal) RE are configured on the CSI-RS resource.

[0053] Then, for the semi-persistent and periodic CSI reference signal configurations, Figure 3 The CSI trigger state and QCL state per CSI-RS resource in the set of reportingconfig do not need to be configured. Figure 4The QCL state of the periodic CSI-RS and the semi-persistent CSI-RS is directly configured to the corresponding CSI-RS resource through MAC-CE or RRC message.

[0054] In one embodiment, the present application provides an information feedback method, which is applied to a first node, such as Figure 5 As shown, the information feedback method provided in this embodiment mainly includes steps S11, S12 and S13.

[0059] First of all, it should be noted that the beam in this embodiment can be understood as a resource (such as reference signal resources, transmitting end spatial filter, receiving end spatial filter, transmitting end precoding, receiving end precoding, antenna port, antenna weight vector, antenna weight matrix, etc.), and the beam number can be replaced by a resource index (such as a reference signal resource index) because the beam can be bound to some time-frequency code resources for transmission. The beam can also be a transmission (transmission / reception) mode; the transmission mode can include space division multiplexing, frequency domain / time domain diversity, etc.

[0060] In addition, the base station can perform quasi co-location (QCL) configuration for two reference signals and inform the user end to describe the channel characteristic hypothesis. The parameters involved in the quasi co-location include at least Doppler spread, Doppler shift, delay spread, average delay, average gain and spatial parameter (Spatial Rx parameter, or Spatial parameter); wherein the spatial parameter may include spatial receiving parameters, such as arrival angle, spatial correlation of receiving beam, average delay, correlation of time-frequency channel response (including phase information).

[0239] In an exemplary embodiment, the information feedback includes one or more of the following:

[0240] Periodic CSI reporting, semi-continuous CSI reporting, and aperiodic CSI reporting.

[0241] In an exemplary implementation, when the information feedback is a periodic CSI report or a semi-continuous CSI report, within a preset time unit, the first node is prohibited from associating the same grouping information with reporting instances corresponding to different reporting configurations;

[0242] The association relationship of the report configuration in the periodic CSI report is configured through RRC signaling, and the association relationship of the report configuration in the semi-persistent CSI report is configured through MAC-CE signaling.

[0243] In an exemplary embodiment, determining a plurality of report configurations having an associated relationship includes:

[0244] In non-periodic CSI reporting, multiple reporting configurations associated with the same trigger state or the same trigger signaling are determined to have an associated relationship.

[0245] In one embodiment, a channel state information reporting method under multiple reporting instances is provided.

[0246] The group report is carried by a CSI report instance. The report instance may include multiple groups, each of which includes one or more reference signal indices and corresponding channel state information (CSI). The grouping criteria mainly include antenna groups or beam groups. However, in non-ideal backhaul scenarios, there is a large delay between transmission nodes, so information such as group reports may face the problem of not being able to be effectively shared in real time.

[0247] In order to flexibly adapt to the problem of whether there is an ideal backhaul link between multiple transmission nodes, it is necessary to consider whether the report results are reported through the same report instance or divided into multiple report instances and then reported to the corresponding transmission nodes respectively. If multiple report instances are reported to multiple transmission nodes respectively, in the scenario of real-time movement and selection on the UE side, it is necessary to discuss the association relationship between multiple report instances.

[0248] Specifically, the user terminal first needs to determine multiple report configurations that have an associated relationship.

[0249] Further, the association relationship between multiple report configurations can be determined by RRC, MAC-CE or DCI signaling. Alternatively, multiple report configurations are associated with the same transmission parameters, where the transmission parameters include at least one of the following: an association identifier (for example, a report configuration is associated with an association identifier index, and a report configuration with the same index ID is confirmed to be associated), a triggering state, a time domain characteristic (involving periodic, non-periodic and semi-continuous), a bandwidth part (Bandwidth Part, BWP), a carrier unit (Component Carrier, CC), and a repetition parameter.

[0250] Furthermore, a plurality of the report configurations are associated with different control resource pool identifiers (CORESET Pool IDs).

[0251] Furthermore, multiple report instances with an associated relationship need to be in the same time domain unit, where the time domain unit is configured by the second node or is predefined.

[0252] Furthermore, the grouping criteria include at least one of the following:

[0253] Reference signals from respective reporting instances under different said reporting configurations may be received simultaneously;

[0254] Reference signals from the same reporting instance under the same reporting configuration cannot be received simultaneously.

[0255] Or, from the grouping criteria, at least one of the following is included:

[0256] Reference signals from respective reporting instances under different said reporting configurations cannot be received simultaneously;

[0257] Reference signals from the same reporting instance under the same reporting configuration may be received simultaneously.

[0258] Furthermore, the report instance includes at least grouping information and a reference signal.

[0259] Regarding the grouping criteria, at least one of the following requirements needs to be met:

[0260] Reference signals from different grouping information can be received simultaneously;

[0261] Reference signals from the same group information cannot be received simultaneously.

[0262] Alternatively, regarding the grouping criteria, at least one of the following requirements needs to be met:

[0263] Reference signals from the same group information can be received simultaneously;

[0264] Reference signals from different grouping information cannot be received simultaneously.

[0265] Further, multiple report configurations or multiple report instances are grouped into a set, and multiple report instances within the set will satisfy the grouping criteria.

[0266] Furthermore, among the multiple report configurations, one report configuration is configured with a specific identifier, which is used to indicate the start identifier of the multiple report instances.

[0267] Furthermore, the base station can specify the effective time of the associated report instance for each report configuration.

[0268] Alternatively, the user terminal may indicate to the base station the effective time of the report instance.

[0269] Furthermore, the user terminal needs to feedback different or the same grouping information for the specified report configuration.

[0270] Furthermore, SINR and RSRP reports are associated with beam grouping and antenna grouping, respectively, that is, when the user is configured for SINR reporting, the group reporting will be performed based on the beam grouping criterion; and when the user is configured for RSRP reporting, the separate reporting will be performed based on the antenna grouping criterion.

[0271] Specifically, this application discusses periodic, semi-continuous and aperiodic CSI reporting respectively.

[0272] For periodic CSI reporting, two or more reporting configurations are associated. Within a given time unit, the user end cannot associate the same grouping information (eg, user antenna panel) to reporting instances corresponding to different reporting configurations.

[0273] Furthermore, the association is configured via RRC signaling.

[0274] For semi-persistent CSI reporting, two semi-persistent reporting configurations are associated, and within a given time unit, the user end cannot associate the same grouping information (eg, user antenna panel) to reporting instances corresponding to different reporting configurations.

[0275] Further, the association is configured by activating MAC-CE signaling of the semi-persistent CSI reporting.

[0276] For the non-periodic CSI report, the user terminal determines that multiple report configurations associated with the same trigger state are associated. From the perspective of the user terminal implementation, the two report configurations and the antenna panels of the user terminal need to correspond one to one.

[0277] Figure 7 is a schematic diagram of the reporting method under multiple reporting examples provided in this application, such as Figure 7 As shown, the base station sets two report configurations for the user terminal and associates the two report configurations, where report configuration a corresponds to the reference signal set under TRP-1, and report configuration b corresponds to the reference signal set under TRP-2. Therefore, the user terminal will select the reference signal index and the corresponding channel state information (such as RSRP or SINR) under the reference signal set for the two TRPs respectively, and provide report instances respectively. At the same time, the user terminal needs to ensure that the reference signals under the two report instances can be received simultaneously. For example, for TRP-1, the user terminal reports the reference signal index and the corresponding channel state information under Link-1; and for TRP-2, the user terminal reports the reference signal index and the corresponding channel state information under Link-2 and Link-3 respectively. In this case, TRP-1 and TRP-2 can still work effectively at the same time in a non-ideal backhaul scenario.

[0278] In one embodiment, a reporting method based on RSRP and antenna grouping is provided.

[0279] Group reporting needs to solve the problem of multiple base station beams being able to be effectively received simultaneously. In group reporting, the acquisition of channel state information (such as RSRP, SINR) needs to consider the impact of multiple simultaneously received reference signals and the exclusive use of user-side resources by each simultaneously received reference signal on the reported channel state information.

[0280] The following specifically analyzes the methods for the user end to select reference signals and determine channel state information in various scenarios.

[0281] In this embodiment, when "RSRP report" and "antenna group grouping criteria" are configured, the reference signal and RSRP determination method are as follows. Wherein, under the antenna group grouping criteria, reference signals in one group cannot be received simultaneously, and / or reference signals in different groups can be received simultaneously.

[0282] Assume that the user end obtains the corresponding RSRP value P(k,l) for the kth reference signal and the lth user end antenna panel (i.e., group information) after measurement. When group reporting is enabled, N groups are reported, and each group has S reference signals, where the user end supports a maximum of N max groups (for example, the user terminal supports N max antenna panels).

[0283] Step-1: Create N report groups, including N reference signal group sets K a , a=0,1,…,N-1, and N group information l a , a=0,1,…,N-1, and set parameter i=0. It should be noted that at this time, the reference signal group set K a and group information a are all empty sets, that is, only the reference signal grouping set is set, but there is no specific reference signal index in the set, and the grouping information l a There is no definite value either.

[0284] Step-2: Determine the best reference signal index k from the RSRP set s and group information s .

[0285]

[0286] Step-3: Given group information l s The best S reference signals are determined as follows.

[0287] s=0

[0288]

[0289] Step-4: Determine the S reference signals as the reference signal set K under the i-th group i , the optimal grouping information l s Determine the group information l under the i-th group i .

[0290] Step-5: When parameter i=N-1, output reference signal group set K a and group information a ; Otherwise, remove the selected group information l s The relevant RSRP set P = P / P(:,l s ), get the updated RSRP set, set i=i+1, and then jump to Step-2.

[0291] It should be noted that '\' means removing the element. Specifically, P / P(x,y) means removing the element P(x,y) from the set P, that is, setting At the same time, the values ​​of other elements in set P and their corresponding indexes remain unchanged.

[0292] For example, when configuring "RSRP report" and "antenna group grouping criteria", the contents of the grouping report are shown in Table 1. It should be noted that, considering that the grouping information in each group is the same, under a specified format, only one grouping information can be reported for each group. In addition, one grouping information can be reported for each reference signal index, and then whether it belongs to the same group can be determined based on the same grouping information.

[0293] Table 1 Antenna group group report under RSRP

[0294]

[0295] In one embodiment, a reporting method based on RSRP and beam grouping is provided.

[0296] In this embodiment, when "RSRP report" and "beam grouping criteria" are configured, the reference signal and RSRP determination method are as follows. Different from the above embodiment, under the beam grouping criteria, reference signals in one group can be received simultaneously, and / or reference signals in different groups cannot be received simultaneously.

[0297] Assume that the user end measures the kth reference signal and the lth user antenna panel, and obtains the corresponding RSRP value P(k,l). When group reporting is enabled, N groups are reported, and each group contains S reference signals, where the user end supports a maximum of S in one group. max Reference signal (for example, the user terminal supports S max antenna panels).

[0298] Step-1: Create N report groups, including a reference signal group set K a, a=0,1,…,N-1, antenna panel set L, and set parameter i=0.

[0299] Step-2: From the RSRP set, determine the best S user antenna panels in turn by the following method:

[0300] P temp =P

[0301]

[0302] s=0

[0303]

[0304] Step-3: Determine the S reference signals as the reference signal set K under the i-th group i , the S user antenna panels are determined as the antenna panel set L i .

[0305] Step-4: When parameter i=N-1, output reference signal group set K a , a=0,1,…,N-1; otherwise, remove the elements in the RSRP set associated with the selected reference signal to obtain an updated RSRP set.

[0306] s=0

[0307] while(s=S-1){

[0308] P=P\P(K i (s),L(s))}

[0309] i=i+1

[0310] Then jump to Step-2.

[0311] It should be noted that for beam grouping, the grouping information does not need to be reported, because the base station can encode them in sequence according to the order of the reference signal grouping.

[0312] In addition, when reference signal groups are reported from different reporting instances, the UE can still use the above algorithm for flexible TRP / reporting configuration and pairing of UE antenna panels.

[0313] Furthermore, the base station can specify the user to use a given antenna panel and perform corresponding beam selection. In this case, the user end no longer needs to specify the antenna panel. s Determination process.

[0314] For example, when configuring "RSRP report" and "beam group grouping criteria", the content of the grouping report is shown in Table 2. It should be noted that, like "RSRP report" and "antenna group grouping criteria", the grouping information here does not need to report the associated user terminal antenna panel index, but is numbered in sequence, mainly to distinguish the reference signal grouping, and can also be used to simplify the base station end beam indication process (that is, the base station end can directly indicate a beam grouping, rather than indicating multiple reference signal indexes under one grouping).

[0315] Table 2 Antenna group group report under RSRP

[0316]

[0317] In one embodiment, a reporting method based on SINR and antenna grouping is provided.

[0318] Unlike the RSRP method, the SINR-based reference signal group report needs to consider the interference between reference signals and the interference from other users under MU-MIMO. Therefore, under the SINR R(k,l), it is necessary to consider the signal power under a given reference signal k and the interference signal power under the user end receiving beam determined by the reference signal (here, the received power of thermal noise and interference reference signal IMR (including NZP-CSI-RS and ZP-IMR) is considered).

[0319] Under the antenna grouping criterion, because reference signals from different groups can be received simultaneously, but reference signals from the same group cannot be received simultaneously. Therefore, in this case, it is impossible to clearly define the mutual interference problem under a specific combination, so it can be simplified to only consider the SINR of a given reference signal. The details are as follows:

[0320] Assume that the user end measures the kth reference signal and the lth user end antenna panel (i.e., group information), and obtains the corresponding signal to interference noise ratio R(k,l). When group reporting is enabled, N groups are reported, and each group has S reference signals, where the user end supports a maximum of N max groups (for example, the user terminal supports N max antenna panels).

[0321] Step-1: Create N report groups, where the reference signal group set K a , a=0,1,…,N-1, and grouping information l a , a=0,1,…,N-1, and set parameter i=0.

[0322] Step-2: Determine the best reference signal index k from the RSRP sets and group information s ,

[0323]

[0324] Step-3: Given group information l s Next, determine the best S reference signals,

[0325] s=0

[0326]

[0327] Step-4: Determine the S reference signals as the reference signal set K under the i-th group i , the optimal grouping information is determined as the grouping information l under the i-th group i .

[0328] Step-5: When parameter i=N-1, output reference signal group set K a , and group information l a ; Otherwise, remove the selected group information l s The relevant SINR set R = R\R(:,l s ), i=i+1, and then jump to Step-2. It should be noted that the reference signal group set K a It includes N reference signal sets K i , group information a Includes N group information l i .

[0329] For example, when configuring "SINR report" and "antenna group grouping criteria", the contents of the grouping report are shown in Table 3. Similar to the antenna group grouping report under RSRP, the grouping information in each group is the same. Therefore, in order to save costs, in a specified format, only one grouping information can be reported for each group. In addition, one grouping information can be reported for each reference signal index, and then whether it belongs to the same group can be determined based on the same grouping information.

[0330] Table 3 Antenna group grouping report under SINR

[0331]

[0332] In one embodiment, a reporting method based on SINR and beam grouping under intra-group mutual interference is provided.

[0333] If the intra-group mutual interference is not considered, the reporting method under the beam grouping based on SINR is basically similar to the corresponding method under RSRP, except that the measurement unit needs to be adjusted from RSRP to SINR. In this embodiment, the group reporting method under the intra-group mutual interference scenario is focused on. Because, for beam grouping, the reference signal within a group can be received simultaneously, and / or the reference signals in different groups cannot be received simultaneously. This means that a group is actually associated with this kind of downlink multi-beam simultaneous transmission mode. Assuming that one beam corresponds to one data stream, due to the simultaneous transmission of multiple beams, other beams will interfere with this beam. It can be seen that in the beam grouping scenario, the reference signal and mutual interference need to consider the influence of the reference signal within the group.

[0334] Within a group, the SINR associated with a reference signal is determined by other reference signals within the group. Furthermore, other reference signals within the group are treated as interference and / or noise for determining the SINR associated with the reference signal. The specific implementation method is as follows: Assuming that the user end obtains the corresponding signal power P(k,l) for the kth reference signal and the lth user antenna panel after measurement, and when the receiving beam determined by the kth reference signal and the lth user antenna panel receives the mth reference signal, the interference power is I(m;k,l). In addition, the background noise such as interference from neighboring cells and thermal noise under the kth reference signal and the lth user antenna panel is n(k,l). After the group report is enabled, N groups are reported, and S reference signals are included in each group, where the user end supports a maximum of S in one group. max Reference signal (for example, the user terminal supports S max antenna panels).

[0335] Step-1: Create N report groups, where the reference signal group set K a , a=0,1,…,N-1, i=0, antenna panel set L.

[0336] Step-2: From the signal power set, select the reference signal and antenna panel combination with the best SINR in turn. Once the reference signal and antenna panel combination are selected, they will be used as the subsequent noise part to finally determine the best S user antenna panels.

[0337] P temp =P

[0338]

[0339] s=0

[0340]

[0341] Step-3: Determine the S reference signals as the reference signal set K under the i-th group i , the user antenna panels with the top S RSRP are determined as the antenna panel set L i ;

[0342] Step-4: When parameter i=N-1, output reference signal group set K a , a=0,1,…,N-1, and the corresponding user-end antenna panel information L a , a=0,1,…,N-1; otherwise, remove the selected reference signal

[0343] s=0

[0344] while(s=S-1){

[0345] P=P\P(K i (s),L i (s))}

[0346] i=i+1

[0347] Then jump to Step-2.

[0348] Similarly, for beam grouping, the grouping information does not need to be reported, because the base station can encode the reference signal groups in the order in which they are grouped.

[0349] For example, when configuring "SINR report" and "beam group grouping criteria", the contents of the group report are shown in Table 4. It should be noted that, although the first selected reference signal does not consider the interference of the later selected reference signal in the reference signal and user antenna panel selection process, the interference of all other reference signal alignments in the group still needs to be taken into account in the report. Specifically, for the xth group, the SINR result under the yth reference signal index is:

[0350]

[0351] Among them, K x (y) represents the reference signal sent by the base station corresponding to the yth reference signal index in the xth group, L x (y) represents the user antenna group corresponding to the yth reference signal index in the xth group, P(K x (y),L x (y)) indicates that in K x (y) and L x (y) received signal power, n(K x (y),L x (y)) indicates that in K x(y) and L x (y) noise power, I(m; K x (y),L x (y)) represents the x (y) and L x (y) The receiving antenna panel and receiving beam determined by the receiving antenna panel to receive the received signal power of the mth reference signal, m∈(K x \K x (y)) means m belongs to the set K x The following does not include element K x One of the remaining elements of (y).

[0352] Table 4 Beam grouping report under SINR

[0353]

[0354]

[0355] In one embodiment, a group reporting scenario is provided in a low frequency band (sub-6 GHz) scenario.

[0356] In the low-frequency band (sub-6GHz) NR scenario, downlink multi-beam transmission is very important for URLLC scenarios and high-speed railway scenarios, and can significantly improve the stability of the entire link through multi-beam diversity gain. In this scenario, the group report reports multiple simultaneously received beam pairs (for example, considering the SINR of mutual interference within the group, the user end will perform digital beamforming at the receiving end under multiple receiving antennas similar to the above-6GHz scenario), and can still effectively cooperate with the base station to quickly select the optimal transmission beam combination.

[0357] Figure 8 Schematic diagram of reporting method under multiple reporting examples provided in the embodiment of the present application, such as Figure 8 As shown. For the two RRHs, the base station configures two reference signal sets: reference signal set A {CSI-RS#0, CSI-RS#1, CSI-RS#2, CSI-RS#3} and reference signal set B {CSI-RS#4, CSI-RS#5, CSI-RS#6, CSI-RS#7}. The user end needs to select two reference signals from different reference signal sets. For example, CSI-RS#0 and CSI-RS#6 form a group, in which the calculation of SINR needs to consider other reference signals in the group as interference reference signals, and output the SINR results of the two reference signals. After receiving the two reference signals, the base station will configure the corresponding TRS for real-time time domain and frequency domain tracking of the user end.

[0358] In summary, based on the UE-side channel quality measurement and other measurement information (for example, the camera's detection of the human body direction), the fed-back power parameters and channel state information, the impact of the MPE directly or indirectly fed back to the base station and the index of the uplink beam considering the MPE, effectively assist the base station in making decisions on the subsequent uplink channel and reference signal uplink beam scheduling, significantly improving the system performance.
