Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

In an exemplary implementation manner, fig. 1 is a schematic flowchart of a data processing method provided in an embodiment of the present application. The data processing method may be performed by a data processing device configured at the first communication node, which 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 transmitting end (e.g., a base station) may use one or more transmit antennas to transmit channels and signals. The CHannel includes a Physical Downlink Control CHannel (PDCCH); the PDCCH carries Downlink Control Information (DCI); the PDCCH is loaded on one or more Control Channel Elements (CCEs). The Signal includes a Channel-State Information Reference Signal (CSI-RS). A receiving end (e.g., a UE) may receive a channel (e.g., PDCCH) and a signal (e.g., CSI-RS) using one or more receive antennas.

In the case where the UE uses more receiving antennas to receive channels or signals, the power consumption of the UE may be high. Then, reducing the number of receive antennas of the UE may reduce power consumption of the UE. In the case where 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 may reduce power consumption of the base station.

In the case where the UE has reduced one or more receive antennas and the base station does not know that the UE has reduced the number of receive antennas, then the base station may misinterpret the behavior of the UE. For example, in a case where the UE reports that one Rank Indicator (RI) is RI 2, the base station may consider that the UE is an RI calculated by using 4 receiving antennas. In practice, the UE turns off 2 receiving antennas for power saving, and the UE uses 2 receiving antennas to calculate the computed RI. If a misinterpretation is generated, Channel-State Information (CSI) is unreliable. Unreliable CSI may lead to decoding errors or energy waste. In order to make the CSI reliable and the UE power saving, some method is needed to constrain the behavior of the base station and the UE.

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

For the case where multiple TRPs serve one UE, each TRP can independently transmit PDCCH to the UE; one of the TRPs may also transmit a PDCCH to the UE, while the other TRPs do not transmit the PDCCH but transmit a Physical Downlink Shared Channel (PDSCH), and the PDSCH carries traffic data of the UE. In the case of many PDCCHs to be decoded by the UE, the UE consumes much power. Then, a certain method is needed to enable the UE to receive data over multiple TRPs, to have certain flexibility in receiving data, and to save power for the UE.

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

Channels and/or signals on the BWP may be transmitted in a beam manner. In the case of a large number of beams received by the UE, a large amount of power is consumed.

For the above situation, 3GPP has not determined how to operate to save power for the UE. The electric quantity of the first communication node can be effectively saved. As shown in fig. 1, the data processing method provided by the present application includes S110, S120, and S130.

The serving cell (i.e., per-serving cell) may be considered to be the current serving cell to be measured.

Here, how to determine the number of ports for measuring the CSI-RS based on the maximum MIMO layer number for the serving cell and the maximum MIMO layer number for each BWP in the serving cell is not limited as long as the maximum MIMO layer number for the serving cell and the maximum MIMO layer number for each BWP in the serving cell are considered in determining the number of ports for measuring the CSI-RS.

Namely, the number of ports of the CSI-RS to be measured by the user equipment is between (maxMIMO-Layers-BWP +1) and maxMIMO-Layers-serving cell.

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

the channel state information reports configuration information, i.e., CSI-ReportConfig. Optionally, the CSI-ReportConfig may include resources of the CSI-RS for measuring channel state information and a port index for rank 8 (i.e., PortIndexFor8 Ranks). Optionally, the value range of portIndexFor8Ranks is {8 port index (i.e. portIndex8), 4 port index (portIndex4), 2 port index (portIndex2), single port index (portIndex1) }.

A resource of the CSI-RS for measuring channel state information, i.e., resourcesForChannelMeasurement. Optionally, the value of the resource of the CSI-RS for measuring the channel state information may be a CSI resource configuration number (i.e., CSI-ResourceConfigId). The base station may configure the UE with one or more CSI resource configuration numbers. Each CSI resource configuration number corresponds to a detailed CSI-RS resource (e.g., a time domain resource, a frequency domain resource, etc.).

The maximum MIMO layer number maxmimos-Layers-serving cell for the serving cell. The value range is {1, 2, 4, 8 }.

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

And resource mapping of the channel state information reference signal, namely CSI-RS-ResourceMaping. The CSI-RS-ResourceMaping contains the number of ports nroflorts of the CSI-RS. The range of values of nroflorts is { p1, p2, p4, p8, p12, p16, p24, p32 }. Where p1 represents one port, p2 represents 2 ports, and so on. For example, assuming nroflorts ═ p2, the antenna ports (i.e., antenna port numbers) of the CSI-RS resources are 0 and 1. As another example, assuming nroflorts ═ p4, the ports of the CSI-RS resource are 0, 1, 2, and 3.

Secondly, the base station transmits CSI-RS of several ports. For example, 4-port CSI-RS is transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to port 0, the 2 nd CSI-RS resource corresponds to port 1, the 3rd CSI-RS resource corresponds to port 2, and the 4 th CSI-RS resource corresponds to port 3. These CSI-RS resources are used for UE measurement and reporting CSI.

Then, the UE determines the number of CSI-RS resources (here, equal to the number of ports) to be measured by itself according to the smaller value of the maximum MIMO layer number maxmimos-Layers-serving cell for each serving cell and the maximum MIMO layer number maxmimos-Layers-BWP for each BWP in the serving cell, which are configured by the base station. For example, in the case of maxMIMO-Layers-serving cell ═ 4 and maxMIMO-Layers-BWP ═ 2 of BWP to be currently measured, the UE selects min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) ═ min (4,2) ═ 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 by itself according to the minimum value of the maximum MIMO layer number maxmimos-Layers-serving cell for each serving cell and the maximum MIMO layer number maxmimos-Layers-BWP for each BWP in the serving cell configured by the base station. For example, if the maxMIMO-Layers-serving cell is 4 and the serving cell has 4 BWPs, the maxMIMO-Layers-BWPs of the 4 BWPs are 4,4,2, respectively, then the UE selects min (maxMIMO-Layers-serving cell, 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 by itself according to the maximum MIMO layer number maxmimors-Layers-serving cell configured by the base station for each serving cell. For example, if maxMIMO-Layers-serving cell is 4, the UE selects 4 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 by itself according to the minimum value of the maximum MIMO layer number maxmimors-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 maxmimors-BWPs of the 4 BWPs are 4,4,2, and 1, respectively, the UE selects min (maxmimors-BWP 1, maxmimors-BWP 2, axMIMO-BWP 3, maxmimors-BWP 4) ═ min (4,4,2,1) ═ 1 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 by the UE according to the maximum value of the maximum MIMO layer number maxmimors-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 maxmimors-BWPs of the 4 BWPs are 4,4,2, and 1, respectively, the UE selects max (maxmimors-Layers-BWP 1, maxmimors-Layers-BWP 2, axMIMO-Layers-BWP3, maxmimors-Layers-BWP 4) ═ 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 by itself (here, equal to the number of ports to be measured by itself) according to the smaller value of the number of ports nroflorts of the CSI-RS configured by the base station and the maximum MIMO layer number maxmimors-Layers BWP for each BWP in the serving cell. For example, if the base station configures 4 CSI-RS resources (here, 4 ports; nroflorts-4) and maxmimos-Layers-BWP of BWP to be currently measured is 2, the UE selects min (nroflorts, maxmimos-Layers-BWP) min (4,2) 2 CSI-RS resources to measure and report CSI.

Optionally, when selecting CSI-RS resources (also referred to herein as antenna ports of CSI-RS; because a one-to-one configuration is assumed in the foregoing), the UE may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the smallest port number to measure, which is 2 CSI-RS resources. That is, the CSI-RS resources with port numbers 0 and 1 are selected. And then, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects the CSI-RS resources, the UE may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the largest port number to measure. I.e. CSI-RS resources with port numbers 2 and 3 are selected. And then, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects the CSI-RS resource, the UE may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the smallest port number and an even number to measure. That is, the CSI-RS resources with port numbers 0 and 2 are selected. And then, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects the CSI-RS resource, the UE may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the smallest port number and an odd number to measure. That is, CSI-RS resources with port numbers 1 and 3 are selected. And then, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects the CSI-RS resource, it may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the smallest measurement period of the CSI-RS as 2 CSI-RS resources to measure. Assuming that the periods of the 1 st, 2 nd, 3 th and 4 th CSI-RS resources are 20, 40 and 40 slots, respectively, the UE selects the CSI-RS resources with port numbers 0 and 1 to make CSI measurement. And then, the UE reports the CSI according to the measurement result. And if the periods of the CSI-RS resources are the same, selecting the CSI-RS resource with the smallest port number from the CSI-RS resources with the same period to measure.

Optionally, when the UE selects the CSI-RS resource, it may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) with the largest CSI-RS measurement period to be 2 CSI-RS resources for measurement. Assuming that the periods of the 1 st, 2 nd, 3 th and 4 th CSI-RS resources are 20, 40 and 40 slots, respectively, the UE selects the CSI-RS resources with port numbers 2 and 3 to make CSI measurements. And then, the UE reports the CSI according to the measurement result. And if the periods of the CSI-RS resources are the same, selecting the CSI-RS resource with the largest port number from the CSI-RS resources with the same period to measure.

Optionally, when the UE selects the CSI-RS resource, 2 min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP) nearest to the CSI reporting time may be selected for measurement.

Optionally, when the UE selects the CSI-RS resources, it may select min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP)/2 ═ 1 with the smallest port number and min (maxMIMO-Layers-serving cell, maxMIMO-Layers-BWP)/2 ═ 1 with the largest port number to measure. That is, CSI-RS resources with port numbers 0 and 3 are selected. And then, the UE reports the CSI according to the measurement result.

After receiving the CSI, the base station knows that the UE uses the CSI-RS resources of the port numbers defined above (e.g., the port numbers 0 and 1) to measure the CSI-RS resources. Therefore, possible misunderstanding between the base station and the UE is avoided, data transmission between the base station and the UE can be more reliable, and power can be saved. In addition, since the UE reduces the measurement of the 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 the UE with some resources and parameters. The configuration parameters include one or more of:

the channel state information reports configuration information, i.e., CSI-ReportConfig. Optionally, the CSI-ReportConfig includes a resource of CSI-RS for measuring channel state information, PortIndexFor8Ranks for a port index of rank 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 }.

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

The maximum MIMO layer number maxmimos-Layers-serving cell for each serving cell. The value range is {1, 2, 4, 8 }.

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

Secondly, the base station transmits CSI-RS of several ports. For example, 8-port CSI-RS is transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to antenna port 0, the 2 nd CSI-RS resource corresponds to port 1, the 3rd CSI-RS resource corresponds to port 2, the 4 th CSI-RS resource corresponds to port 3, the 5th CSI-RS resource corresponds to port 4, the 6 th CSI-RS resource corresponds to port 5, the 7 th CSI-RS resource corresponds to port 6, and the 8 th CSI-RS resource corresponds to port 7. These 8 CSI-RS resources are used for UE measurement and reporting CSI.

Then, the UE determines the number of CSI-RS resources (here, equal to the number of ports) to be measured by itself according to the maximum MIMO layer number maxmimors-Layers-serving cell configured by the base station for each serving cell. For example, if maxmimos-Layers-serving cell-4, the UE may select maxmimos-Layers-serving cell-1-4-1-3 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 by itself according to the maximum MIMO layer number maxMIMO-Layers-BWP configured by the base station for each BWP in the serving cell. For example, if maxmimors-Layers-BWP of BWP to be currently measured is 2, the UE may select 3 CSI-RS resources to measure and report CSI for maxmimors-Layers-BWP + 1-2-1. This option is possible because 3< 8.

Optionally, the number of ports of the CSI-RS to be measured by the UE is min (maxMIMO-Layers-serving cell, (maxMIMO-Layers-BWP + 1)). Optionally, the number of ports of the CSI-RS to be measured by the UE is between (maxMIMO-Layers-BWP +1) and maxMIMO-Layers-serving cell. Optionally, the number of ports of the CSI-RS to be measured by the UE is max (1, (maxmimos-Layers-serving cell-1)). If the maxMIMO-Layers-serving cell is not configured, then the maxMIMO-Layers-serving cell may be determined based on the energy of the UE (e.g., taking the value of the maximum number of MIMO Layers that the UE can support).

Optionally, when the UE selects CSI-RS resources (also referred to herein as antenna ports of CSI-RS; because a one-to-one configuration is assumed in the foregoing), the UE may select 3 CSI-RS resources with the smallest port number for measurement. That is, CSI-RS resources with port numbers 0, 1, and 2 are selected. And then, the UE reports the CSI according to the measurement result.

Optionally, when the UE selects CSI-RS resources (also referred to herein as antenna ports of CSI-RS; because a one-to-one configuration is assumed in the foregoing), the UE may select 3 CSI-RS resources with the largest port number for measurement. I.e. CSI-RS resources with port numbers 5, 6 and 7 are selected. And then, the UE reports the CSI according to the measurement result.

After receiving the CSI, the base station knows that the UE uses the CSI-RS resources of the port numbers defined above (e.g., the port numbers 0, 1, and 2) to measure the CSI-RS resources. Therefore, possible misunderstanding between the base station and the UE is avoided, data transmission between the base station and the UE can be more reliable, and power can be saved. In addition, the UE reduces the measurement of CSI-RS resources with port numbers of 3-7, so that the power consumption can be reduced.

In one embodiment, the base station configures the UE with some resources and parameters. The configuration parameters include one or more of:

Type I Single Panel rank indication Restriction typeI-singlePanel-ri Restriction. The parameters are bitmap types r7, r6, r5, r4, r3, r2, r1, r 0. That is, the parameter has 7 bits, r7 is the most significant bit, and r0 is the least significant bit. Any one of the 7 bits may take the value 0 or 1.

The type I multi-panel rank indication limits ri recovery. The parameters are bitmap types r3, r2, r1, r 0. That is, the parameter has 4 bits, r3 is the most significant bit, and r0 is the least significant bit. Any one of the 4 bits may take the value 0 or 1.

For example, if maxmimos-Layers-BWP of the BWP to be currently measured is 4 and type I single panel rank indication Restriction typeI-SinglePanel-ri retransmission is 00000011, the UE may select min (maxmimos-Layers-BWP, sum (typeI-SinglePanel-ri retransmission)) min (4, sum (00000011)) -min (4,2) = 2 CSI-RS resources to measure and report CSI. In this regard, sum () represents the accumulation of the values of the binary bits. Alternatively, the UE may select the 2 CSI-RS resources with the smallest port number to measure. That is, the CSI-RS resources with port numbers 0 and 1 are selected. And then, 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 by itself according to the maximum MIMO layer number maxMIMO-Layers-BWP and the type I single panel rank indication Restriction type I-single panel-ri Restriction configured by the base station for each BWP in the serving cell. For example, if maxmimos-Layers-BWP of the BWP to be currently measured is 4 and the type I single panel rank indication Restriction typeI-SinglePanel-ri Restriction is 00001000, the UE may select min (maxmimos-Layers-BWP, I) min (4,4) 4 CSI-RS resources to measure and report CSI. In this case, i represents the position (number from right to left; number from 1) of the highest order bit of 1 for the binary bit.

For example, if maxMIMO-Layers-BWP of the BWP to be currently measured is 4 and the type I multi-panel rank indication limit ri Restriction is 0011, 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. Alternatively, the UE may select the 2 CSI-RS resources with the smallest port number to measure. That is, the CSI-RS resources with port numbers 0 and 1 are selected. And then, the UE reports the CSI according to the measurement result.

For example, if maxMIMO-Layers-BWP of the BWP to be currently measured is 2 and the type II rank indication Restriction typeII-RI Restriction is 01, 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. Alternatively, the UE may select the 1 CSI-RS resource with the smallest port number to measure. That is, the CSI-RS resource with port number 0 is selected. And then, 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 by the UE according to the maximum MIMO layer number maxMIMO-Layers-BWP and the type II port selection rank indication Restriction type II-portselectrionri Restriction configured by the base station for each BWP in the serving cell. For example, if maxMIMO-Layers-BWP of the BWP to be currently measured is 2 and the type II port selection rank indication Restriction typeII-portselectrionri Restriction is 01, the UE may select min (maxMIMO-Layers-BWP, sum (typeII-portselectrionrirestriction)) min (2, sum (01)) -min (2,1) — 1 CSI-RS resource to measure and report CSI. Alternatively, the UE may select the 1 CSI-RS resource with the smallest port number to measure. That is, the CSI-RS resource with port number 0 is selected. And then, the UE reports the CSI according to the measurement result.

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

Optionally, the maximum layer number in the CSI feedback refers to a value of the rank indication RI.

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

Optionally, the UE determines its maximum number of Layers in CSI feedback according to the maximum MIMO layer number maxMIMO-Layers-BWP and type II port selection rank indication Restriction type II-portselectrionri Restriction configured by the base station for each BWP in the serving cell. Optionally, the maximum layer number in the CSI feedback refers to a value of the rank indication RI.

Optionally, the UE restricts the configuration of ri-triggering according to maxMIMO-Layers-BWP in CSI feedback. The configuration of the limit ri-recovery includes: the value of the maximum rank indication RI allowing feedback in the RI-recovery does not exceed maxMIMO-Layers-BWP-1. Where rank indicates that the RI is numbered from 0. For example, if maxMIMO-Layers-BWP is 2, the maximum rank indication RI in RI-triggering that allows feedback takes the value 0 or 1. Then, the ri-recovery may be binary 0011 or 0001.

Optionally, the UE determines the maximum number of Layers in the CSI feedback according to min (max mimo-Layers-BWP, (RI-maximum rank indication RI value +1) indicated by RI-triggering) in the CSI feedback. For example, if maxMIMO-Layers-BWP is 4, then the maximum rank indication RI in RI-triggering that allows feedback takes the value of 1, and then the maximum number of Layers for the UE in CSI feedback is 2. Optionally, the maximum layer number in the CSI feedback refers to a value of the rank indication RI. I.e. the maximum value of the rank indication RI is 2 (note: here counting from 1).

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

Optionally, when the report quantity reporting quantity when the UE reports the CSI is configured to cri-RI-CQI, the UE determines the maximum number of Layers when performing CSI feedback by itself according to min (the maximum rank value allowed in maxMIMO-Layers-BWP, PortIndexFor8 Ranks). For example, if maxMIMO-Layers-BWP is 2 and PortIndexFor8Ranks takes portindendex 4, then the maximum number of Layers for the UE when performing CSI feedback is 2. Optionally, the maximum value of the rank indication RI fed back by the UE is 2 (note: counting from 1 here).

Optionally, the base station configures the rank limit ri-Restriction of the user equipment according to the maximum MIMO layer number of the BWP level configured for the user equipment, i.e. the maximum MIMO layer number maxMIMO-Layers-BWP for BWP. Wherein the value of the maximum rank indication RI allowing feedback in the RI-recovery does not exceed maxMIMO-Layers-BWP-1. Where rank indicates that the RI is numbered from 0. For example, if maxMIMO-Layers-BWP is 2, the maximum rank indication RI in RI-triggering that allows feedback takes the value 0 or 1. Then, the ri-recovery may be binary 0011 or 0001.

Optionally, the base station configures portIndexFor8Ranks of the user equipment according to the maximum MIMO layer number maxMIMO-Layers-BWP of the BWP level configured for the user equipment. When the report quantity of the base station to the user equipment is configured to be cri-RI-CQI, the port index in the PortIndexFor8Ranks configured by the base station to the user equipment does not exceed maxMIMO-Layers-BWP. Wherein the port index takes on { portIndex1, portIndex2, portIndex4, and portIndex8 }. For example, if maxMIMO-Layers-BWP is 2, PortIndexFor8Ranks may take the value { portIndex1, portIndex2 }.

After receiving the CSI, the base station knows that the UE uses the CSI-RS resources of the port numbers defined above (e.g., the port numbers 0 and 1) to measure the CSI-RS resources. Therefore, possible misunderstanding between the base station and the UE is avoided, data transmission between the base station and the UE can be more reliable, and power can be saved. In addition, the UE reduces the measurement of the CSI-RS resource with the port number of 2-7, so that the power consumption can be reduced.

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

The channel state information reports configuration information CSI-ReportConfig. Optionally, the CSI-ReportConfig includes a resource of CSI-RS for measuring channel state information, PortIndexFor8Ranks for a port index of rank 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 }.

A power-save channel (i.e., downlink control information scrambled by a power-save radio network temporary identity (CRC), DCI with CRCscrambled by PS-RNTI, DCI Format 3_0, carried by PDCCH). The power save channel indicates how many CSI-RS ports the UE needs to measure. Alternatively, the base station may configure the indication information for some UEs and not configure the indication information for other UEs.

The UE can report the maximum MIMO layer number maxMIMO-Layers-Desired of the UE to the base station. One UE can report only one such value at a time (e.g., maxMIMO-Layers-Desired ═ 2).

Secondly, the base station transmits CSI-RS of several ports. For example, 4-port CSI-RS is transmitted. Optionally, each CSI-RS resource corresponds to one antenna port. For example, the first CSI-RS resource corresponds to antenna port 0, the 2 nd CSI-RS resource corresponds to port 1, the 3rd CSI-RS resource corresponds to port 2, and the 4 th CSI-RS resource corresponds to port 3. These 4 CSI-RS resources are used for UE measurement and CSI reporting.

Second, the base station transmits a power-save channel. Indicating 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 by itself from the power save channel. For example, the power save channel has one bit to indicate how many CSI-RS ports the UE needs to measure. If the bit is 0, the UE needs to measure maxMIMO-Layers-serving cell CSI-RS ports. If maxMIMO-Layers-serving cell equals 4, then the UE needs to measure 4 CSI-RS ports. Alternatively, the UE may select 4 CSI-RS resources with the smallest port number to measure. I.e. CSI-RS resources with port numbers 0-3 are selected. And then, the UE reports the CSI according to the measurement result.

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

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

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

Alternatively, the UE determines the number of CSI-RS resources (here, equal to the number of ports) to be measured by itself according to a one-bit wake-up bit of the power save channel. For example, if the wake-up bit is 1, the UE needs to measure 4 CSI-RS ports. Alternatively, the UE may select 4 CSI-RS resources with the smallest port number to measure. I.e. CSI-RS resources with port numbers 0-3 are selected. And then, the UE reports the CSI according to the measurement result.

Alternatively, the UE determines the number of CSI-RS resources (here equal to the number of ports) to be measured by itself according to a function specified by a one-bit wake-up bit of the power save channel. For example, if the wake-up bit specifies a function of "no wake-up", the UE needs to measure 2 CSI-RS ports. Alternatively, the UE may select the 2 CSI-RS resources with the smallest port number to measure. That is, the CSI-RS resources with port numbers 0 and 1 are selected. And then, the UE reports the CSI according to the measurement result.

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

After receiving the CSI, the base station knows that the UE uses the CSI-RS resources of the port numbers defined above (e.g., the port numbers 0 and 1) to measure the CSI-RS resources. Therefore, possible misunderstanding between the base station and the UE is avoided, data transmission between the base station and the UE can be more reliable, and power can be saved. In addition, the UE reduces the measurement of the CSI-RS resource with the port number of 2-3, so that the power consumption can be reduced.

Optionally, the UE may report maxMIMO-Layers-Desired according to its own evaluation. After receiving the maxMIMO-Layers-Desired values, the base station synthesizes the maxMIMO-Layers-Desired values reported by each UE, and if most of the UEs report that the maxMIMO-Layers-Desired values are 2, the base station may configure the number of downlink antenna ports to be 2. Alternatively, the base station transmits using antenna ports 0 and 1. Optionally, the antenna ports of the CSI-RS configured by the base station to the UE are 0 and 1. Optionally, the antenna ports of the tracking reference signal TRS configured by the base station to the UE are 0 and 1. This can reduce power consumption of the base station.

In one embodiment, the different TRPs may be connected with ideal backhaul (with negligible transmission delay) or with non-ideal backhaul (with transmission delay taken into account).

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

Configuration information of the transmitting and receiving points. Such as the ID of the TRP, the set of control resources available to the TRP CORESET (including the ID of CORESET). Alternatively, CORESET may be shared among multiple TRPs. That is, one CORESET may be used for one or more TRPs. Alternatively, the use may be shared by scrambling codes corresponding to IDs of different TRPs. Alternatively, the use may be shared by antenna ports corresponding to IDs of different TRPs. Alternatively, the usage may be shared by DCI formats corresponding to IDs of different TRPs. Alternatively, the use can be shared by control channel element CCE offsets corresponding to IDs of different TRPs.

A power-save channel (i.e., DCI with CRC coded by PS-RNTI).

TRP of a single DCI or Multiple DCIs Desired by the UE operates MTRP-Multiple-DCI-Desired. If the MTRP-Multiple-DCI-Desired is True, identifying TRP operation of the UE expecting Multiple DCIs; otherwise the UE expects TRP operation of a single DCI.

Second, the base station transmits a power-saving channel to the UE. Alternatively, the base station may transmit a power save channel to the UE with one or more TRPs. For example, 2 power save channels are transmitted to the UE with 2 TRPs. Alternatively, the contents of the 2 power save channels may be different. Optionally, the 2 power save channels carry IDs of TRPs. Optionally, the contents of the 2 power save channels are identical except for the ID of the TRP. Optionally, if the UE receives power saving channels with inconsistent contents from different TRPs, ignoring all the power saving channels; optionally, the UE remains in the original state in this case (e.g., not awake; remains in a sleep state; remains in an inactive state DRX-OFF). Optionally, if the UE receives power saving channels with inconsistent contents except the IDs of the TRPs from different TRPs, ignoring all the power saving channels; optionally, the UE remains in the original state in this case (e.g., not awake; remains in a sleep state; remains in an inactive state DRX-OFF).

Alternatively, the base station may indicate the number of CORESET for the TRP (or the maximum number of CORESET for the TRP) to the UE in the power save channel. For example, if the base station indicates the UE in the power save channel, the number of CORESET for TRP is 2, then the UE should not use CORESET's ID beyond 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 blindly detect the CORESET with the ID of 2-4, thereby saving power.

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

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