Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

In an exemplary implementation, FIG. 1 is a schematic flowchart of a data processing method provided by an embodiment of the present application. The data processing method may be executed by a data processing device configured in the first communication node, the device may be implemented by software and/or hardware, and integrated on the first communication node. The first communication node may be a UE.

In a MIMO system, a transmitter (eg, a base station) can use one or more transmit antennas to transmit channels and signals. The channels include a physical downlink control channel (Physical Downlink Control CHannel, PDCCH); the PDCCH carries downlink control information (Downlink Control Information, DCI); the PDCCH is loaded on one or more control channel elements (Control Channel Element, CCE). The signal includes a channel state information reference signal (Channel-State Information Reference Signal, CSI-RS). A receiver (eg, UE) may use one or more receive antennas to receive channels (eg, PDCCH) and signals (eg, CSI-RS).

In the case that the UE uses more receiving antennas to receive channels or signals, the UE may consume more power. Then, reducing the number of receiving antennas of the UE can reduce the power consumption of the UE. When the base station uses more transmit antennas to transmit channels or signals, the base station may consume more power. Then, reducing the number of transmit antennas of the base station can reduce the power consumption of the base station.

In the case where the UE reduces one or more receive antennas and the base station is not aware that the UE has reduced the number of receive antennas, then the base station may misinterpret the behavior of the UE. For example, when the UE reports a rank indicator (Rank Indicator, RI) as RI=2, the base station may consider that the UE uses 4 receive antennas to calculate the RI. In fact, the UE turns off two receiving antennas to save power, and the UE uses the two receiving antennas to calculate the RI. If a misunderstanding occurs, the Channel-State Information (CSI) is unreliable. Unreliable CSI may lead to decoding errors or wasted energy. In order to make the CSI reliable and the UE to save power, there needs to be a certain method to constrain the behavior of the base station and the UE.

In a MIMO system, a communication device (eg, a base station) may have multiple transmit and receive points TRP. A communication device (eg, a UE) may receive channels and signals from one or more TRPs. A TRP can have one or more transmit/receive antennas. Each TRP can transmit and receive channels and signals independently.

For the case where multiple TRPs serve one UE, each TRP can transmit the PDCCH to the UE independently; or one of the TRPs can transmit the PDCCH to the UE, and the other TRPs do not need to transmit the PDCCH, but transmit the physical downlink shared channel (Physical Downlink Shared Channel). Shared Channel, PDSCH), PDSCH carries service data of the UE. When the UE needs to decode a lot of PDCCHs, the UE will consume a lot of power. Then, there needs to be a certain method to enable the UE to receive data on multiple TRPs, to have certain flexibility in receiving data, and to save power for the UE.

For the 5th Generation mobile communication system (5G), that is, New Radio Access Technology (NR), 5G-NR. The base station and the UE may operate on one BandWidth Part (BWP). Operations on the aforementioned channels and/or signals can also be performed on one BWP.

Channels and/or signals on the aforementioned BWPs may be transmitted in beams. When the number of beams received by the UE is large, a lot of power will be consumed.

In view of the above situation, 3GPP has not yet determined how to operate so as to save power of the UE. The present application can effectively save the power of the first communication node. As shown in FIG. 1 , the data processing method provided by this application includes S110 , S120 and S130 .

In one embodiment, the number of ports measured in this example does not exceed the configured maximum number of MIMO layers, that is, MaxMIMOLayer. The base station configures some resources and parameters for the UE. The content of the configuration is the configuration parameter, and the configuration parameter includes at least one or more of the following:

Channel state information reports configuration information, ie CSI-ReportConfig. Optionally, the CSI-ReportConfig may include CSI-RS resources for measuring channel state information and a port index for rank 8 (ie, PortIndexFor8Ranks). Optionally, the value range of PortIndexFor8Ranks is {8-port index (ie, portIndex8), 4-port index (portIndex4), 2-port index (portIndex2), and single-port index (portIndex1)}.

The CSI-RS resources used to measure channel state information, namely resourcesForChannelMeasurement. Optionally, the value of the CSI-RS resource used for measuring the channel state information may be a CSI resource configuration number (ie, CSI-ResourceConfigId). The base station may configure one or more CSI resource configuration numbers for the UE. Each CSI resource configuration number corresponds to a detailed CSI-RS resource (eg, time domain resource, frequency domain resource, etc.).

The maximum number of MIMO layers for the serving cell maxMIMO-Layers-ServingCell. Its value range is {1, 2, 4, 8}.

The maximum number of MIMO layers maxMIMO-Layers-BWP for BWP in the serving cell. Its value range is {1, 2, 4, 8}. Optionally, the value of maxMIMO-Layers-BWP does not exceed maxMIMO-Layers-ServingCell of the serving cell where the BWP is located. The value of the maximum number of MIMO layers of at least one BWP is equal to the maximum number of MIMO layers of the serving cell where the BWP is located.

The resource mapping of the channel state information reference signal, that is, CSI-RS-ResourceMapping. The CSI-RS-ResourceMapping includes the number of CSI-RS ports nrofPorts. The value range of nrofPorts is {p1,p2,p4,p8,p12,p16,p24,p32}. Among them, p1 represents one port, p2 represents 2 ports, and so on. For example, assuming nrofPorts=p2, the antenna ports (ie, antenna port numbers) of the CSI-RS resources are 0 and 1. For another example, assuming that nrofPorts=p4, the ports of the CSI-RS resources are 0, 1, 2 and 3.

Second, the base station transmits CSI-RS for several ports. For example, 4 ports of CSI-RS are transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to port 0, the second CSI-RS resource corresponds to port 1, the third CSI-RS resource corresponds to port 2, and the fourth CSI-RS resource corresponds to port 3. These CSI-RS resources are used by the UE to measure and report CSI.

Then, the UE determines the value to be measured according to the smaller value of the maximum number of MIMO layers maxMIMO-Layers-ServingCell configured by the base station for each serving cell and the maximum number of MIMO layers maxMIMO-Layers-BWP for each BWP in the serving cell. The number of CSI-RS resources (here equal to the number of ports). For example, in the case of maxMIMO-Layers-ServingCell=4 and maxMIMO-Layers-BWP of the BWP currently to be measured=2, the UE selects min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=min(4,2 ) = 2 CSI-RS resources to measure and report CSI.

Optionally, the UE determines that it wants to measure according to the minimum value of the maximum number of MIMO layers maxMIMO-Layers-ServingCell configured by the base station for each serving cell and the maximum number of MIMO layers maxMIMO-Layers-BWP for each BWP in the serving cell. the number of CSI-RS resources (here equal to the number of ports). For example, if maxMIMO-Layers-ServingCell=4 and the serving cell has 4 BWPs, and the maxMIMO-Layers-BWPs of these 4 BWPs are 4, 4, 2, and 2, respectively, then the UE selects min(maxMIMO-Layers-ServingCell , maxMIMO-Layers-BWP1, maxMIMO-Layers-BWP2, maxMIMO-Layers-BWP3, maxMIMO-Layers-BWP4)=min(4,4,4,2,2)=2 CSI-RS resources to measure and report CSI .

Optionally, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured according to the maximum number of MIMO layers maxMIMO-Layers-ServingCell configured by the base station for each serving cell. For example, if maxMIMO-Layers-ServingCell=4, then the UE selects 4 CSI-RS resources to measure and report CSI.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the minimum value of the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell. For example, if the serving cell has 4 BWPs, and the maxMIMO-Layers-BWP of these 4 BWPs are 4, 4, 2, and 1, respectively, then the UE selects min(maxMIMO-Layers-BWP1, maxMIMO-Layers-BWP2, axMIMO -Layers-BWP3, maxMIMO-Layers-BWP4)=min(4,4,2,1)=1 CSI-RS resource to measure and report CSI.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the maximum value of the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell. For example, if the serving cell has 4 BWPs, and the maxMIMO-Layers-BWP of these 4 BWPs are 4, 4, 2, and 1, respectively, then the UE selects max(maxMIMO-Layers-BWP1, maxMIMO-Layers-BWP2, axMIMO -Layers-BWP3, maxMIMO-Layers-BWP4)=max(4,4,2,1)=4 CSI-RS resources to measure and report CSI.

Optionally, the UE determines the number of CSI-RS resources to be measured according to the smaller value of the number of CSI-RS ports nrofPorts configured by the base station and the maximum number of MIMO layers maxMIMO-Layers-BWP for each BWP in the serving cell ( Here it is equal to the number of ports you want to measure). For example, if the base station is configured with 4 CSI-RS resources (here, 4 ports; nrofPorts=4) and maxMIMO-Layers-BWP of the BWP currently to be measured=2, then the UE selects min(nrofPorts, maxMIMO-Layers- BWP)=min(4,2)=2 CSI-RS resources to measure and report CSI.

Optionally, when the UE selects the CSI-RS resource (here, it also refers to the antenna port of the CSI-RS; because the one-to-one configuration method is assumed above), the UE can select the min with the smallest port number (maxMIMO-Layers-ServingCell, maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources with the largest port number for measurement. That is, CSI-RS resources with port numbers 2 and 3 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources with the smallest port number and an even number for measurement. That is, CSI-RS resources with port numbers 0 and 2 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources with the smallest port number and an odd number for measurement. That is, CSI-RS resources with port numbers 1 and 3 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources with the smallest CSI-RS measurement period for measurement. Assuming that the periods of the first, second, third, and fourth CSI-RS resources are 20, 20, 40, and 40 slots, respectively, the UE will select the CSI-RS resources with port numbers 0 and 1 for CSI measurement. After that, the UE reports the CSI according to the measurement result. If the periods of the CSI-RS resources are the same, then, among the CSI-RS resources of the same period, the CSI-RS resource with the smallest port number is selected for measurement.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources with the largest CSI-RS measurement period for measurement. Assuming that the periods of the first, second, third, and fourth CSI-RS resources are 20, 20, 40, and 40 slots, respectively, the UE will select the CSI-RS resources with port numbers 2 and 3 for CSI measurement. After that, the UE reports the CSI according to the measurement result. If the periods of the CSI-RS resources are the same, then, among the CSI-RS resources of the same period, the CSI-RS resource with the largest port number is selected for measurement.

Optionally, when selecting CSI-RS resources, the UE may select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)=2 CSI-RS resources closest to the CSI reporting time for measurement.

Optionally, when selecting CSI-RS resources, the UE can select min(maxMIMO-Layers-ServingCell, maxMIMO-Layers-BWP)/2=1 with the smallest port number and min(maxMIMO-Layers- ServingCell, maxMIMO-Layers-BWP)/2=1 CSI-RS resource to measure. That is, CSI-RS resources with port numbers 0 and 3 are selected. After that, the UE reports the CSI according to the measurement result.

After receiving the above-mentioned CSI, the base station knows that the UE uses the CSI-RS resources of the previously defined port numbers (eg, the port numbers are 0 and 1) to measure and obtain the result. Thus, possible misunderstanding between the base station and the UE can be avoided, and the data transmission between the base station and the UE can be made more reliable, thereby saving power. In addition, since the UE reduces the measurement of CSI-RS resources with port numbers 2 and 3, power consumption can also be reduced.

In one embodiment, the number of ports measured in this example exceeds the configured MaxMIMOLayer, and the base station configures some resources and parameters for the UE. Configuration parameters include one or more of the following:

Channel state information reports configuration information, ie CSI-ReportConfig. Optionally, the CSI-ReportConfig includes CSI-RS resources for measuring channel state information, and port index PortIndexFor8Ranks for a rank of 8. Optionally, the value range of PortIndexFor8Ranks is {8-port index portIndex8, 4-port index portIndex4, 2-port index portIndex2, and single-port index portIndex1}.

The resource resourcesForChannelMeasurement of the CSI-RS used to measure the channel state information. Optionally, the value of resourcesForChannelMeasurement is the CSI resource configuration number CSI-ResourceConfigId. The base station may configure one or more CSI resource configuration numbers for the UE. Each CSI resource configuration number corresponds to a detailed CSI-RS resource (eg, time domain resource, frequency domain resource, etc.).

The maximum number of MIMO layers maxMIMO-Layers-ServingCell for each serving cell. Its value range is {1, 2, 4, 8}.

The maximum number of MIMO layers maxMIMO-Layers-BWP for each BWP in the serving cell. Its value range is {1, 2, 4, 8}. Optionally, the value of maxMIMO-Layers-BWP does not exceed maxMIMO-Layers-ServingCell of the serving cell where the BWP is located. The value of the maximum number of MIMO layers of at least one BWP is equal to the maximum number of MIMO layers of the serving cell where the BWP is located.

Second, the base station transmits CSI-RS for several ports. For example, 8 ports of CSI-RS are transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to antenna port 0, the second CSI-RS resource corresponds to port 1, the third CSI-RS resource corresponds to port 2, the fourth CSI-RS resource corresponds to port 3, and the fifth The CSI-RS resource corresponds to port 4, the sixth CSI-RS resource corresponds to port 5, the seventh CSI-RS resource corresponds to port 6, and the eighth CSI-RS resource corresponds to port 7. These 8 CSI-RS resources are used for UE to measure and report CSI.

Then, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured according to the maximum number of MIMO layers maxMIMO-Layers-ServingCell configured by the base station for each serving cell. For example, if maxMIMO-Layers-ServingCell=4, then the UE may select maxMIMO-Layers-ServingCell-1=4-1=3 CSI-RS resources to measure and report CSI.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell. For example, if the current BWP to be measured has maxMIMO-Layers-BWP=2, then the UE can select maxMIMO-Layers-BWP+1=2-1=3 CSI-RS resources to measure and report CSI. Since 3<8, this selection method is feasible.

Optionally, the number of CSI-RS ports to be measured by the UE is min(maxMIMO-Layers-ServingCell,(maxMIMO-Layers-BWP+1)). Optionally, the number of CSI-RS ports to be measured by the UE is between (maxMIMO-Layers-BWP+1) and maxMIMO-Layers-ServingCell. Optionally, the number of CSI-RS ports to be measured by the UE is max(1, (maxMIMO-Layers-ServingCell-1)). If maxMIMO-Layers-ServingCell is not configured, maxMIMO-Layers-ServingCell may be determined according to the energy of the UE (eg, taking the value of the maximum number of MIMO layers that the UE can support).

Optionally, when the UE selects CSI-RS resources (here, it also refers to the antenna port of CSI-RS; because a one-to-one configuration is assumed in the foregoing), the UE can select the 3 CSI-RS resources with the smallest port numbers to measure . That is, CSI-RS resources with port numbers 0, 1, and 2 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects CSI-RS resources (here, it also refers to the antenna port of CSI-RS; because a one-to-one configuration is assumed in the foregoing), the UE can select the 3 CSI-RS resources with the largest port numbers to measure . That is, CSI-RS resources with port numbers 5, 6 and 7 are selected. After that, the UE reports the CSI according to the measurement result.

After receiving the above-mentioned CSI, the base station knows that the UE uses the CSI-RS resources of the previously defined port numbers (eg, the port numbers are 0, 1 and 2) to measure and obtain the result. Thus, possible misunderstanding between the base station and the UE can be avoided, and the data transmission between the base station and the UE can be made more reliable, thereby saving power. In addition, since the UE reduces the measurement of CSI-RS resources with port numbers 3-7, power consumption can also be reduced.

In one embodiment, the base station configures some resources and parameters for the UE. Configuration parameters include one or more of the following:

Channel state information reports configuration information, ie CSI-ReportConfig. Optionally, the CSI-ReportConfig includes CSI-RS resources for measuring channel state information, and port index PortIndexFor8Ranks for a rank of 8. Optionally, the value range of PortIndexFor8Ranks is {8-port index portIndex8, 4-port index portIndex4, 2-port index portIndex2, and single-port index portIndex1}.

Optionally, the value of maxMIMO-Layers-BWP does not exceed maxMIMO-Layers-ServingCell of the serving cell where the BWP is located. The value of the maximum number of MIMO layers of at least one BWP is equal to the maximum number of MIMO layers of the serving cell where the BWP is located.

Second, the base station transmits CSI-RS for several ports. For example, 8 ports of CSI-RS are transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to antenna port 0, the second CSI-RS resource corresponds to port 1, the third CSI-RS resource corresponds to port 2, the fourth CSI-RS resource corresponds to port 3, and the fifth The CSI-RS resource corresponds to port 4, the sixth CSI-RS resource corresponds to port 5, the seventh CSI-RS resource corresponds to port 6, and the eighth CSI-RS resource corresponds to port 7. These 8 CSI-RS resources are used for UE to measure and report CSI.

Then, the UE determines the number of CSI-RS resources to be measured according to the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell and the type I-SinglePanel-ri Restriction type I-SinglePanel-ri Restriction ( is equal to the number of ports here). For example, if the current BWP to be measured has maxMIMO-Layers-BWP=4, and the type I single panel rank indication restriction typeI-SinglePanel-ri Restriction=00000011, then the UE may select min(maxMIMO-Layers-BWP,sum(typeI -SinglePanel-riRestriction))=min(4,sum(00000011))=min(4,2)=2 CSI-RS resources to measure and report CSI. Here, sum() means to accumulate the values of binary bits. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Here, i represents the position of the most significant bit that is 1 for a binary bit (counting from right to left; counting from 1). Optionally, the UE may select 4 CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0-3 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to number of ports). For example, if the current BWP to be measured has maxMIMO-Layers-BWP=4, and the Type I multi-panel rank indication restriction ri Restriction=0011, then the UE may select min(maxMIMO-Layers-BWP, sum(ri Restriction))= min(4, sum(0011)) = min(4, 2) = 2 CSI-RS resources to measure and report CSI. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports). For example, if the current BWP to be measured has maxMIMO-Layers-BWP=2, and the Type II rank indication restriction typeII-RI Restriction=01, then the UE may select min(maxMIMO-Layers-BWP, sum(typeII-RI Restriction) )=min(2,sum(01))=min(2,1)=1 CSI-RS resource to measure and report CSI.

For example, if the current BWP to be measured has maxMIMO-Layers-BWP=2, and the type II port selection rank indication restriction typeII-PortSelectionRI Restriction=01, then the UE may select min(maxMIMO-Layers-BWP,sum(typeII-PortSelectionRIRestriction ))=min(2,sum(01))=min(2,1)=1 CSI-RS resource to measure and report CSI. Optionally, the UE may select the CSI-RS resource with the smallest port number for measurement. That is, the CSI-RS resource whose port number is 0 is selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines its own maximum layer in CSI feedback according to the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell and type I-SinglePanel-ri Restriction number. Optionally, the maximum number of layers in the CSI feedback refers to the rank indicating the value of RI.

Optionally, the UE determines the maximum number of layers in the CSI feedback according to the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell and the type I multi-panel rank indication restriction ri Restriction.

Optionally, the UE determines the maximum number of layers in CSI feedback according to the maximum number of MIMO layers maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell and type II-PortSelectionRI Restriction. Optionally, the maximum number of layers in the CSI feedback refers to the rank indicating the value of RI.

Optionally, the UE restricts the configuration of ri-Restriction according to maxMIMO-Layers-BWP in the CSI feedback. The configuration of restricting the ri-Restriction includes: the maximum rank indication RI allowed to be fed back in the ri-Restriction does not take more than maxMIMO-Layers-BWP-1. Among them, the rank indicates that the RIs are numbered from 0. For example, if maxMIMO-Layers-BWP=2, the maximum rank indication RI allowed to be fed back in ri-Restriction is 0 or 1. Then, ri-Restriction can be 0011 or 0001 in binary.

Optionally, the UE determines the maximum number of layers in the CSI feedback for the UE according to min(maxMIMO-Layers-BWP, (the value of the maximum rank indication RI indicated by ri-Restriction+1)) in the CSI feedback. For example, if maxMIMO-Layers-BWP=4, then the maximum rank indication RI allowed to be fed back in ri-Restriction is 1, and the maximum number of layers in the CSI feedback of the UE is 2. Optionally, the maximum number of layers in the CSI feedback refers to the rank indicating the value of RI. That is, the rank indicates that the maximum value of RI is 2 (note: the count starts from 1 here).

Optionally, when the report quantity ReportQuantity when the UE reports CSI is configured as cri-RI-CQI, the maximum rank value allowed in the PortIndexFor8Ranks of the UE does not exceed maxMIMO-Layers-BWP. For example, if maxMIMO-Layers-BWP=2, then PortIndexFor8Ranks can take the value of {portIndex1, portIndex2}.

For example, if maxMIMO-Layers-BWP=2 and PortIndexFor8Ranks takes portIndex4, then the maximum number of layers when the UE performs CSI feedback is 2. Optionally, the maximum value of the rank indication RI fed back by the UE is 2 (Note: the count starts from 1 here).

Optionally, the base station configures the rank restriction ri-Restriction of the user equipment according to the maximum number of MIMO layers of the BWP level configured for the user equipment, that is, the maximum number of MIMO layers for BWP maxMIMO-Layers-BWP. Wherein, the maximum rank that is allowed to be fed back in ri-Restriction indicates that the value of RI does not exceed maxMIMO-Layers-BWP-1. Among them, the rank indicates that the RIs are numbered from 0. For example, if maxMIMO-Layers-BWP=2, the maximum rank indication RI allowed to be fed back in ri-Restriction is 0 or 1. Then, ri-Restriction can be 0011 or 0001 in binary.

Optionally, the base station configures the PortIndexFor8Ranks of the user equipment according to the maximum number of MIMO layers maxMIMO-Layers-BWP of the BWP level configured for the user equipment. Wherein, when the ReportQuantity configured by the base station for the user equipment is cri-RI-CQI, the port index in the PortIndexFor8Ranks configured by the base station for the user equipment does not exceed maxMIMO-Layers-BWP. The value of the port index is {portIndex1, portIndex2, portIndex4, portIndex8}. For example, if maxMIMO-Layers-BWP=2, then PortIndexFor8Ranks can take the value of {portIndex1, portIndex2}.

After receiving the above-mentioned CSI, the base station knows that the UE uses the CSI-RS resources of the previously defined port numbers (eg, the port numbers are 0 and 1) to measure and obtain the result. Thus, possible misunderstanding between the base station and the UE can be avoided, and the data transmission between the base station and the UE can be made more reliable, thereby saving power. In addition, since the UE reduces the measurement of CSI-RS resources with port numbers 2-7, power consumption can also be reduced.

In one embodiment, the power saving channel (ie DCI with CRC scrambled by PS-RNTI) is indicated in this application. The power saving channel is PDCCH scrambled by PS-RNTI, or DCI format 3-0. The base station configures some resources and parameters for the UE.

The value of the maximum number of MIMO layers of at least one BWP is equal to the maximum number of MIMO layers of the serving cell where the BWP is located.

Power saving channel (ie, downlink control information scrambled with CRC temporarily identified by the power saving wireless network; DCI with CRC scrambled by PS-RNTI; DCI Format 3_0; carried by PDCCH). The power saving channel indicates how many CSI-RS ports the UE needs to measure. Optionally, the base station may configure the indication information for some UEs, but not configure the indication information for other UEs.

The UE can report to the base station the maximum number of MIMO layers maxMIMO-Layers-Desired that the UE expects. A UE can only report one such value (eg, maxMIMO-Layers-Desired=2) at a time.

Second, the base station transmits CSI-RS for several ports. For example, 4 ports of CSI-RS are transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to antenna port 0, the second CSI-RS resource corresponds to port 1, the third CSI-RS resource corresponds to port 2, and the fourth CSI-RS resource corresponds to port 3. These 4 CSI-RS resources are used for UE to measure and report CSI.

Next, the base station transmits the power saving channel. Indicates how many CSI-RS ports the UE needs to measure.

Then, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured according to the power saving channel. For example, the power saving channel has one bit to indicate how many CSI-RS ports the UE needs to measure. If this bit is 0, the UE needs to measure maxMIMO-Layers-ServingCell CSI-RS ports. If maxMIMO-Layers-ServingCell is equal to 4, the UE needs to measure 4 CSI-RS ports. Optionally, the UE may select 4 CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0-3 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured according to the power saving channel. For example, the power saving channel has one bit to indicate how many CSI-RS ports the UE needs to measure. If this bit is 1, the UE needs to measure maxMIMO-Layers-BWP CSI-RS ports. If maxMIMO-Layers-BWP is equal to 2, then the UE needs to measure 2 CSI-RS ports. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured according to the power saving channel. For example, the power saving channel indicates that the UE needs to measure 2 CSI-RS ports. Then the UE needs to measure 2 CSI-RS ports. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the one-bit wake-up bit of the power saving channel. For example, if the wake-up bit is 0, the UE needs to measure 2 CSI-RS ports. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the one-bit wake-up bit of the power saving channel. For example, if the wake-up bit is 1, the UE needs to measure 4 CSI-RS ports. Optionally, the UE may select 4 CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0-3 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the function specified by the one-bit wake-up bit of the power saving channel. For example, if the function specified by the wake-up bit is "not wake-up", the UE needs to measure 2 CSI-RS ports. Optionally, the UE may select two CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0 and 1 are selected. After that, the UE reports the CSI according to the measurement result.

Optionally, the UE determines the number of CSI-RS resources to be measured (here equal to the number of ports) according to the function specified by the one-bit wake-up bit of the power saving channel. For example, if the function specified by the wake-up bit is "wake-up", then the UE needs to measure 4 CSI-RS ports. Optionally, the UE may select 4 CSI-RS resources with the smallest port numbers to measure. That is, CSI-RS resources with port numbers 0-3 are selected. After that, the UE reports the CSI according to the measurement result.

After receiving the above-mentioned CSI, the base station knows that the UE uses the CSI-RS resources of the previously defined port numbers (eg, the port numbers are 0 and 1) to measure and obtain the result. Thus, possible misunderstanding between the base station and the UE can be avoided, and the data transmission between the base station and the UE can be made more reliable, thereby saving power. In addition, since the UE reduces the measurement of CSI-RS resources with port numbers 2-3, power consumption can also be reduced.

Optionally, the UE may report maxMIMO-Layers-Desired according to its own evaluation. After receiving the above maxMIMO-Layers-Desired, the base station integrates the maxMIMO-Layers-Desired values reported by each UE. If most UEs report maxMIMO-Layers-Desired=2, the base station can configure the number of downlink antenna ports to 2. Optionally, the base station uses antenna ports 0 and 1 to transmit. Optionally, the antenna ports of the CSI-RS configured by the base station for the UE are 0 and 1. Optionally, the antenna ports of the tracking reference signal TRS configured by the base station for the UE are 0 and 1. This can reduce the power consumption of the base station.

In one embodiment, ideal backhaul connections (with negligible transmission delay) or non-ideal backhaul connections (transmission delays need to be considered) may be used between different TRPs.

First, the base station configures some resources and parameters for the UE.

Configuration information for transmit and receive points. For example, the ID of the TRP, the control resource set CORESET available to the TRP (including the ID of the CORESET). Optionally, CORESET can be shared among multiple TRPs. That is, one CORESET can be used by one or more TRPs. Optionally, it can be shared and used through scrambling codes corresponding to IDs of different TRPs. Optionally, the antenna ports corresponding to the IDs of different TRPs can be shared and used. Optionally, DCI formats corresponding to IDs of different TRPs can be shared and used. Optionally, the CCE offsets of the control channel elements corresponding to the IDs of different TRPs can be shared and used.

Power saving channel (ie, DCI with CRC scrambled by PS-RNTI).

TRP operation MTRP-Multiple-DCI-Desired for single DCI or multiple DCI desired by the UE. If MTRP-Multiple-DCI-Desired is True, it indicates that the UE expects TRP operation of multiple DCI; otherwise, the UE expects TRP operation of single DCI.

Secondly, the base station transmits the power saving channel to the UE. Optionally, the base station may use one or more TRPs to transmit the power saving channel to the UE. For example, 2 power saving channels are transmitted to the UE with 2 TRPs. Optionally, the contents of the two power saving channels may be different. Optionally, the 2 power saving channels carry TRP IDs. Optionally, except for the ID of the TRP, the contents of the two power saving channels are exactly the same. Optionally, if the UE receives power-saving channels with inconsistent content from different TRPs, all power-saving channels are ignored; Sleep state; remain in the inactive state DRX-OFF). Optionally, if the UE receives power-saving channels with inconsistent content except the ID of the TRP from different TRPs, all power-saving channels are ignored; optionally, the UE keeps the original state in this case ( For example, do not wake up; stay in sleep state; stay in inactive state DRX-OFF).

Optionally, the base station may indicate to the UE the number of CORESETs for TRP (or the maximum number of CORESETs for TRP) in the power saving channel. For example, if the base station instructs the UE in the power saving channel that the number of CORESETs for TRP is 2, the UE shall use the ID of the CORESET not to exceed the indicated value (here 2). In this case, the ID of the CORESET that the UE needs to blindly detect is 0 or 1. That is, the UE does not need to blindly detect CORESETs whose IDs are 2-4, thereby saving power.

Then, the UE reports to the base station that the UE expects a single DCI or multiple DCI TRP operation MTRP-Multiple-DCI-Desired. For example, if the data volume of the service currently running by the UE is small, the UE may report MTRP-Multiple-DCI-Desired as False.

After that, the base station receives the MTRP-Multiple-DCI-Desired reported by the UE. If MTRP-Multiple-DCI-Desired is False, then the base station can configure single DCI TRP operation or single TRP for the UE. Since the UE reduces the reception of TRP or reduces the reception of DCI, the UE can save a part of power.
