Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.
The steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.
In an exemplary implementation, fig. 1 is a schematic flow chart of a data processing method according to an embodiment of the present application. The data processing method may be performed by a data processing device arranged at the first communication node, which device may be implemented in software and/or hardware and integrated at 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 transmit channels and signals using one or more transmit antennas. Channels include, physical downlink control channels (Physical Downlink Control chnnel, 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 signals include Channel-state information reference signals (CSI-RS). A receiving end (e.g., UE) may receive a channel (e.g., PDCCH) and a signal (e.g., CSI-RS) with one or more receive antennas.
In the case where the UE uses more receive antennas to receive the channel or signal, the UE may consume more power. Then, reducing the number of receive antennas of the UE may reduce power consumption of the UE. In the case that 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 is unaware that the UE has reduced the number of receive antennas, then the base station may misunderstand the behavior of the UE. For example, in the case where the UE reports a Rank Indicator (RI) of ri=2, the base station may consider the UE to be RI calculated by using 4 receiving antennas. In practice, the UE turns off 2 receive antennas for power saving, and the UE calculates RI using 2 receive antennas. If misunderstanding occurs, channel State Information (CSI) is unreliable. Unreliable CSI may lead to decoding errors or energy waste. In order to make CSI reliable and UE power saving, a certain method is needed to constrain the behavior of the base station and 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 a channel and a signal from one or more TRPs. One TRP may have one or more transmit/receive antennas. Each TRP may independently transmit and receive channels and signals.
For the case where multiple TRPs serve one UE, each TRP may independently transmit PDCCH to the UE; the PDCCH may also be transmitted by one of the TRPs to the UE, while the other TRP does not transmit the PDCCH, but transmits a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) carrying the traffic data of the UE. In case that the UE needs a lot of PDCCHs to be decoded, the UE consumes much power. Then, a certain method is needed to enable the UE to receive the data above the plurality of TRPs, to have a certain flexibility in receiving the data, and to save power.
For the 5th generation mobile communication system (5th Generation mobile communication system,5G), i.e. the new radio access technology (New Radio Access Technology, NR), 5G-NR. The base station and the UE may operate on one BandWidth Part (BWP). The operations on the channels and/or signals described above may also be performed on a BWP.
The channels and/or signals on the BWP may be transmitted in a beam manner. In case the number of beams received by the UE is large, the stripe consumes much power.
For the above situation, the 3GPP has not yet determined how to operate, so as to enable the UE to save power. The application can effectively save the electric quantity of the first communication node. As shown in fig. 1, the data processing method provided by the present application includes S110, S120, and S130.
S110, acquiring configuration parameters.
The first communication node may obtain the configuration parameters from the second communication node. The means of acquisition is not limited herein. The configuration parameters include one or more of the following:
resources of the CSI-RS for measuring channel state information; reporting configuration information by channel state information; the maximum MIMO layer number for the service cell, i.e. maxMIMO-Layers-serving cell; the maximum number of MIMO Layers for BWP in the serving cell, i.e. maxmmo-Layers-BWP, wherein each BWP has a respective value; rank indication limitation; configuration information of transmitting and receiving points.
The serving cell (i.e., per-serving cell) may be considered to be the serving cell currently to be measured. The BWP (i.e., per-Cell) may be considered as the BWP to be currently measured in the serving Cell. The configuration information of the transmitting and receiving points may be regarded as configuration information of TRP.
S120, receiving data according to the configuration parameters.
The data includes one or more of the following: signals and channels. The signal and the channel may be received simultaneously.
In one embodiment, the receiving data according to the configuration parameters includes:
and determining the port number for measuring the CSI-RS according to the configuration parameters. I.e. the user equipment determines the port number of the CSI-RS resource to be measured according to the parameters configured by the base station. And the whole CSI-RS resource is not required to be measured, so that the electric quantity is saved.
In one embodiment, the determining the port number for measuring the CSI-RS resource according to the configuration parameter includes: the number of ports for measuring the CSI-RS is determined according to the maximum MIMO layer number for each BWP in the serving cell. I.e. the user equipment determines the number of ports of CSI-RS to be measured by itself from the value of the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell configured by the base station.
In this example, the maximum MIMO layer number for each BWP in the serving cell may be directly determined as the port number for the measurement CSI-RS, or the result of adding 1 to the maximum MIMO layer number for each BWP in the serving cell may be determined as the port number for the measurement CSI-RS.
In one embodiment, determining the number of ports for measuring CSI-RS according to the maximum MIMO layer number for each BWP in the serving cell includes: the result of adding 1 to the maximum MIMO layer number for each BWP in the serving cell is determined as the port number of the measurement CSI-RS. I.e. the number of ports of CSI-RS to be measured by the user equipment is maxmmo-Layers-bwp+1.
In one embodiment, the determining the port number for measuring the CSI-RS resource according to the configuration parameter includes: the port number for measuring the CSI-RS is determined according to the maximum MIMO layer number for the serving cell and the maximum MIMO layer number for each BWP in the serving cell. I.e. the user equipment determines the port number of the CSI-RS to be measured according to the value of the maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell and the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell configured by the base station. How to determine the number of ports to measure 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 here 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 when determining the number of ports to measure the CSI-RS.
In one embodiment, the determining the port number of the measurement CSI-RS according to the maximum MIMO layer number for the serving cell and the maximum MIMO layer number for each BWP in the serving cell includes at least one of: determining a minimum value of a maximum MIMO layer number for the serving cell and a maximum MIMO layer number for each BWP in the serving cell as a port number for measuring CSI-RS; that is, the user equipment determines the port number of the CSI-RS to be measured according to the maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell and the smaller value of the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell configured by the base station.
Determining a maximum MIMO layer number for each BWP in the serving cell plus one and a minimum value of the maximum MIMO layer number for the serving cell as a port number for measuring CSI-RS; namely, the port number of the CSI-RS to be measured by the user equipment is min (maxMIMO-relays-ServerCell, (maxMIMO-relays-BWP+1)); the number between the maximum MIMO layer number for each BWP in the serving cell plus one and the maximum MIMO layer number for the serving cell is determined as the port number of the measurement CSI-RS. I.e. the number of ports of CSI-RS to be measured by the user equipment is between (maxmmo-Layers-bwp+1) and maxmmo-Layers-serving cell.
In one embodiment, the determining the port number for measuring the CSI-RS resource according to the configuration parameter includes at least one of: determining the result of subtracting 1 from the maximum MIMO layer number of the serving cell as the port number of the measurement CSI-RS resource; namely, the port number of the CSI-RS to be measured by the user equipment is maxMIMO-relays-Servercell-1;
the maximum MIMO layer number for the serving cell is subtracted by 1, and the minimum value of 1 is determined as the port number for measuring CSI-RS resources. I.e. the number of ports of CSI-RS to be measured by the user equipment is max (1, (maxmmo-Layers-serving cell-1)).
In one embodiment, the receiving data according to the configuration parameters includes:
and selecting the CSI-RS resources of the port number according to a set rule. Namely, when the user equipment selects the CSI-RS resources, the CSI-RS resources with the number of the ports are selected according to a certain rule.
The setting rule may be set according to actual circumstances. Such as according to the size of the port number, measurement period, CSI reporting time, etc.
In one embodiment, the setting rule includes at least one of:
selecting CSI-RS resources of the port number with the smallest port number;
selecting CSI-RS resources of the port number with the largest port number;
Selecting CSI-RS resources of the port number with the minimum measurement period;
and selecting the CSI-RS resources with the largest measurement period and the largest port number.
In one embodiment, the determining the port number for measuring the CSI-RS resource according to the configuration parameter includes: the number of measurement CSI-RS ports is determined according to the maximum MIMO layer number and type I single-panel rank indication limit for each BWP in the serving cell. I.e. the user equipment determines the number of CSI-RS ports to be measured by itself according to the maximum MIMO layer number maxmmo-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.
In an example, the present application may determine the number of measurement CSI-RS ports based on the result of accumulating the maximum MIMO layer number for each BWP in the serving cell and the binary bit values of the type I single-panel rank indication limitation; or determining the number of the measurement CSI-RS ports according to the position of the highest bit with the binary bit of 1 of the single-panel rank indication limitation of the type I and the maximum MIMO layer number of each BWP in the service cell.
In one embodiment, the determining the number of measurement CSI-RS ports according to the maximum MIMO layer number and the type I single-panel rank indication limit for each BWP in the serving cell comprises: the result of accumulating the binary bit values of the type I single-panel rank indication limitation and the minimum value of the maximum MIMO layer number for each BWP in the serving cell are determined as the measurement CSI-RS port number. I.e. the user equipment selects min (maxMIMO-Layers-BWP, sum (typeI-single Panel-ri allocation)) CSI-RS ports. Where min () is the smaller of the 2 taken ones and sum () represents accumulating the value of a binary bit.
In one embodiment, the determining the number of measurement CSI-RS ports according to the maximum MIMO layer number and the type I single-panel rank indication limit for each BWP in the serving cell comprises: the location of the highest bit of the type I single-panel rank indication restriction, where the highest bit of 1 is located, and the minimum value of the maximum MIMO layer number for each BWP in the serving cell are determined as the measured CSI-RS port number. I.e. the user equipment may select min (maxMIMO-Layers-BWP, i) CSI-RS ports. Here, i represents the position where the highest bit of the binary bits 1 for the rank indication limitation is located.

In one embodiment, the number of ports measured in this example does not exceed the configured maximum MIMO layer number, maxMIMOLayer. The base station configures some resources and parameters for the UE, wherein the configuration content is configuration parameters, and the configuration parameters at least comprise one or more of the following:
The channel state information reports configuration information, i.e., CSI-ReportConfig. Alternatively, CSI-ReportConfig may include resources of CSI-RS for measuring channel state information and a port index for rank 8 (i.e., portlndexfor 8 Ranks). Optionally, the value range of portIndexFor8Ranks is {8 port index (i.e., portIndex 8), 4 port index (portIndex 4), 2 port index (portIndex 2), single port index (portIndex 1) }.
The resource of CSI-RS for measuring channel state information, i.e., resource escforchannelmeasurement. Alternatively, 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 one or more CSI resource allocation numbers for the UE. Each CSI resource allocation number corresponds to a detailed CSI-RS resource (e.g., time domain resource, frequency domain resource, etc.).
Maximum MIMO layer number maxMIMO-Layers-Servercells for the serving cell. The value range is {1, 2, 4, 8}.
Maximum MIMO layer number maxmmo-Layers-BWP for BWP in serving cell. The value range is {1, 2, 4, 8}. Optionally, the value of the maxMIMO-dyes-BWP does not exceed the maxMIMO-dyes-serving cell of the serving cell in which the 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.
The resource mapping of the channel state information reference signal, namely CSI-RS-resource mapping. Wherein, the CSI-RS-resource mapping comprises the port number nrofPorts of the CSI-RS. The range of nrofPorts is { p1, p2, p4, p8, p12, p16, p24, p32}. Where p1 represents one port, p2 represents 2 ports, and so on. For example, assuming nrofports=p2, the antenna ports (i.e., antenna port numbers) of the CSI-RS resource are 0 and 1. As another example, assuming nrofports=p4, the ports of CSI-RS resources are 0, 1, 2, and 3.
Secondly, the base station transmits CSI-RS of several ports. For example, a 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 3 rd 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.
The UE then determines the number of CSI-RS resources to measure by itself (here, the number of ports) from the base station configured smaller value of the maximum MIMO layer number for each serving cell, maxmmo-Layers-serving cell, and the maximum MIMO layer number for each BWP in the serving cell. For example, in case of maxMIMO-dyes-bwp=2 of BWP to be currently measured and maxMIMO-dyes-bwp=4 of maxMIMO-dyes-BWP, the UE selects min (maxMIMO-dyes-ServingCell, maxMIMO-dyes-BWP) =min (4, 2) =2 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) according to the minimum value of the maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell and the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell, which are configured by the base station. For example, if maxMIMO-dyes-serving cell=4 and the serving cell has 4 BWP's, which are 4,2, respectively, then the UE selects min (maxMIMO-dyes-ServingCell, maxMIMO-dyes-BWP 1, maxMIMO-dyes-BWP 2, maxMIMO-dyes-BWP 3, maxMIMO-dyes-BWP 4) =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 to be measured by itself (here, equal to the number of ports) according to the maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell configured by the base station. For example, if maxMIMO-Layers-serving cell=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 measure by itself (here equal to the number of ports) from the minimum value of the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell, which is configured by the base station. For example, if the serving cell has 4 BWP's, and the maxmmo-Layers-BWP of the 4 BWP's are 4,2, and 1, respectively, the UE selects min (maxmmo-Layers-BWP 1, maxmmo-Layers-BWP 2, axMIMO-Layers-BWP3, maxmmo-Layers-BWP 4) =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 measure by itself (here equal to the number of ports) from the maximum value of the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell, which the base station configures. For example, if the serving cell has 4 BWP's, and the maxmmo-Layers-BWP of the 4 BWP's are 4,2, and 1, respectively, then the UE selects max (maxmmo-Layers-BWP 1, maxmmo-Layers-BWP 2, axMIMO-Layers-BWP3, maxmmo-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 number nrofPorts of CSI-RS configured by the base station and the smaller value of the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell. For example, if the base station is configured with 4 CSI-RS resources (here, 4 ports; nrofports=4) and the maxMIMO-Layers-bwp=2 of the BWP to be currently measured, the UE selects min (nrofPorts, maxMIMO-Layers-BWP) =min (4, 2) =2 CSI-RS resources to measure and report CSI.
Alternatively, the UE may select the min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) =2 CSI-RS resources with the smallest port number to measure when selecting CSI-RS resources (here also referred to as antenna ports of CSI-RS; because a one-to-one configuration was assumed above). That is, CSI-RS resources with port numbers 0 and 1 are selected. And then, the UE reports the CSI according to the measurement result.
Alternatively, when the UE selects CSI-RS resources, the UE may select min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) =2 CSI-RS resources with the largest port number to measure. That is, CSI-RS resources with port numbers 2 and 3 are selected. And then, the UE reports the CSI according to the measurement result.
Alternatively, when the UE selects CSI-RS resources, min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) =2 CSI-RS resources with the smallest port number and even number may be selected for measurement. That is, CSI-RS resources with port numbers 0 and 2 are selected. And then, the UE reports the CSI according to the measurement result.
Alternatively, when the UE selects CSI-RS resources, min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) =2 CSI-RS resources with the smallest port number and odd number may be selected for measurement. 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 CSI-RS resources, min (maxmmo-relays-ServingCell, maxMIMO-relays-BWP) =2 CSI-RS resources with the smallest measurement period of CSI-RS may be selected for measurement. Assuming periods of the 1 st, 2 nd, 3 rd and 4 th CSI-RS resources are 20, 20 th, 40 th and 40 th slots, respectively, the UE will select CSI-RS resources with port numbers 0 and 1 to make CSI measurements. And then, the UE reports the CSI according to the measurement result. 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 for measurement.
Optionally, when the UE selects CSI-RS resources, min (maxmmo-relays-ServingCell, maxMIMO-relays-BWP) =2 CSI-RS resources with the largest measurement period of CSI-RS may be selected for measurement. Assuming periods of the 1 st, 2 nd, 3 rd and 4 th CSI-RS resources are 20, 20 th, 40 th and 40 th slots, respectively, the UE will select 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. 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 in the same period for measurement.
Optionally, when the UE selects CSI-RS resources, min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) =2 CSI-RS resources closest to the CSI reporting time may be selected for measurement.
Alternatively, when the UE selects CSI-RS resources, the min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) with the smallest port number/2=1 and the min (maxmmo-Layers-ServingCell, maxMIMO-Layers-BWP) with the largest port number/2=1 CSI-RS resources may be selected for measurement. 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 with the previously defined port numbers (e.g., port numbers 0 and 1) to obtain the measurement result. Thus, possible misunderstanding between the base station and the UE is avoided, and data transmission between the base station and the UE can be more reliable, so that power can be saved. In addition, since the UE reduces 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 to the UE. The configuration parameters include one or more of the following:
the channel state information reports configuration information, i.e., CSI-ReportConfig. Optionally, the CSI-ReportConfig includes resources of CSI-RS for measuring channel state information, port index PortIndexFor8Ranks for rank 8. Optionally, the value range of portIndexFor8Ranks is { 8-port index portIndex8, 4-port index portIndex4, 2-port index portIndex2, single-port index portIndex1}.
Resource of CSI-RS for measuring channel state information. Optionally, the value of the resourcesforsChannelMeasurement is the CSI resource configuration number CSI-resourceConfigId. The base station may configure one or more CSI resource allocation numbers for the UE. Each CSI resource allocation number corresponds to a detailed CSI-RS resource (e.g., time domain resource, frequency domain resource, etc.).
Maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell. The value range is {1, 2, 4, 8}.
Maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell. The value range is {1, 2, 4, 8}. Optionally, the value of the maxMIMO-dyes-BWP does not exceed the maxMIMO-dyes-serving cell of the serving cell in which the 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 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 2 nd CSI-RS resource corresponds to port 1, the 3 rd CSI-RS resource corresponds to port 2, the 4 th CSI-RS resource corresponds to port 3, the 5 th 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 to be measured by itself (here, equal to the number of ports) according to the maximum MIMO layer number maxMIMO-Layers-serving cell configured by the base station for each serving cell. For example, if maxMIMO-Layers-services cell=4, then the UE may select maxMIMO-Layers-services cell-1=4-1=3 CSI-RS resources to measure and report CSI.
Optionally, the UE determines the number of CSI-RS resources to measure by itself (here equal to the number of ports) according to the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell, which the base station configures. For example, if maxMIMO-Layers-bwp=2 of the BWP to be currently measured, the UE may select maxMIMO-Layers-bwp+1=2-1=3 CSI-RS resources to measure and report CSI. This option is possible because of 3<8.
Optionally, the port number of the CSI-RS to be measured by the UE is min (maxMIMO-relays-ServerCell, (maxMIMO-relays-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-ServeringCell. Alternatively, the port number of the CSI-RS to be measured by the UE is max (1, (maxMIMO-Layers-serving cell-1)). If the maxMIMO-Layers-ServerCell is not configured, the maxMIMO-Layers-ServerCell may be determined based on the energy of the UE (e.g., taking the value of the maximum MIMO layer number that the UE can support).
Alternatively, the UE may select the 3 CSI-RS resources with the smallest port number for measurement when selecting the CSI-RS resources (also referred to herein as the antenna ports of the CSI-RS; since a one-to-one configuration was assumed above). 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.
Alternatively, the UE may select the 3 CSI-RS resources with the largest port number to measure when selecting the CSI-RS resources (also referred to herein as the antenna ports of the CSI-RS; since a one-to-one configuration was assumed above). That is, 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 CSI-RS resources with the previously defined port numbers (e.g., port numbers 0, 1, and 2) to obtain a measurement result. Thus, possible misunderstanding between the base station and the UE is avoided, and data transmission between the base station and the UE can be more reliable, so that power can be saved. In addition, because UE reduces the measurement of CSI-RS resources with port numbers of 3-7, the power consumption can be reduced.
In one embodiment, the base station configures some resources and parameters to the UE. The configuration parameters include one or more of the following:
the channel state information reports configuration information, i.e., CSI-ReportConfig. Optionally, the CSI-ReportConfig includes resources of CSI-RS for measuring channel state information, port index PortIndexFor8Ranks for rank 8. Optionally, the value range of portIndexFor8Ranks is { 8-port index portIndex8, 4-port index portIndex4, 2-port index portIndex2, single-port index portIndex1}.
Resource of CSI-RS for measuring channel state information. Optionally, the value of the resourcesforsChannelMeasurement is the CSI resource configuration number CSI-resourceConfigId. The base station may configure one or more CSI resource allocation numbers for the UE. Each CSI resource allocation number corresponds to a detailed CSI-RS resource (e.g., time domain resource, frequency domain resource, etc.).
Maximum MIMO layer number maxmmo-Layers-serving cell for each serving cell. The value range is {1, 2, 4, 8}.
Maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell. The value range is {1, 2, 4, 8}. Optionally, the value of the maxMIMO-dyes-BWP does not exceed the maxMIMO-dyes-serving cell of the serving cell in which the 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.
Type I single panel rank indication limits typeI-SinglePanel-ri distribution. The parameters are bit map types r7, r6, r5, r4, r3, r2, r1, r0. That is, the parameter has 7 bits, r7 being the most significant bit and r0 being the least significant bit. Any one of the 7 bits may take on a value of 0 or 1.
Type I multi-panel rank indication limits ri distribution. The parameters are bit map types r3, r2, r1, r0. 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 on a value of 0 or 1.
Type II rank indication limits type II-RI Restriction. The parameter is the bit map type r1, r0. That is, the parameter has 2 bits, r1 is the most significant bit, and r0 is the least significant bit. Any one of the 2 bits may take on a value of 0 or 1.
Type II ports select rank indication restriction typeII-PortSelectionRI Restriction. The parameter is the bit map type r1, r0. That is, the parameter has 2 bits, r1 is the most significant bit, and r0 is the least significant bit. Any one of the 2 bits may take on a value of 0 or 1.
Secondly, the base station transmits CSI-RS of several ports. For example, 8-port 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 2 nd CSI-RS resource corresponds to port 1, the 3 rd CSI-RS resource corresponds to port 2, the 4 th CSI-RS resource corresponds to port 3, the 5 th 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.
The UE then determines the number of CSI-RS resources to measure by itself (here, the number of ports) based on the maximum MIMO layer number maxmmo-Layers-BWP for each BWP in the serving cell and type I single panel rank indication Restriction type I-single panel-ri allocation configured by the base station. For example, if maxMIMO-Layers-bwp=4 of the BWP to be currently measured and type I single panel rank indication Restriction type I-single panel-ri allocation=00000011, the UE may select min (maxMIMO-Layers-BWP, sum (type I-single panel-ri allocation))=min (4, sum (00000011))=min (4, 2) =2 CSI-RS resources to measure and report CSI. Here, sum () means accumulating the values of binary bits. Alternatively, the UE may select the 2 CSI-RS resources with the smallest port number for measurement. That is, 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 to measure by itself (here, equal to the number of ports) according to the maximum MIMO layer number maxmmo-Layers-BWP and type I single-panel rank indication Restriction type I-single panel-ri allocation configured by the base station for each BWP in the serving cell. For example, if maxmmo-Layers-bwp=4 of the BWP to be currently measured and type I single panel rank indication Restriction type I-single panel-ri allocation=00001000, the UE may select min (maxmmo-Layers-BWP, I) =min (4, 4) =4 CSI-RS resources to measure and report CSI. Here, i represents the position where the most significant bit of the binary bit 1 is located (right to left; 1).

For example, if maxMIMO-Layers-bwp=4 of the BWP to be currently measured and the type I multi-plane rank indication limits ri allocation=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 for measurement. That is, 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 to measure by itself (here, equal to the number of ports) according to the maximum MIMO layer number maxmmo-Layers-BWP and type II rank indication limitation type II-RI allocation configured by the base station for each BWP in the serving cell. For example, if maxMIMO-Layers-bwp=2 of the BWP to be currently measured and type II rank indication Restriction type II-RI allocation=01, the UE may select min (maxMIMO-Layers-BWP, sum (type II-RI allocation))=min (2, sum (01))=min (2, 1) =1 CSI-RS resource to measure and report CSI.

For example, if maxMIMO-Layers-bwp=2 of the BWP to be currently measured and the type II port selects rank indication restriction type II-PortSelectionRI Restriction =01, the UE may select min (maxMIMO-Layers-BWP, sum (type II-PortSelectionRI Restriction))=min (2, sum (01))=min (2, 1) =1 CSI-RS resources to measure and report CSI. Alternatively, the UE may select the 1 CSI-RS resource with the smallest port number for measurement. That is, CSI-RS resources with port number 0 are 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 maxmmo-Layers-BWP and type I single-panel rank indication Restriction type I-singlecanel-ri Restriction configured by the base station for each BWP in the serving cell. Optionally, the maximum number of layers in CSI feedback refers to the 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 maxmmo-Layers-BWP for each BWP in the serving cell configured by the base station and the type I multi-panel rank indication Restriction ri.

Optionally, the UE determines its maximum number of Layers in CSI feedback according to the maximum MIMO layer number maxmmo-Layers-BWP and type II rank indication Restriction type II-RI Restriction for each BWP in the serving cell configured by the base station. Optionally, the maximum number of layers in CSI feedback refers to the 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 maxmmo-Layers-BWP and type II port selection rank indication restriction type II-PortSelectionRI Restriction configured by the base station for each BWP in the serving cell. Optionally, the maximum number of layers in CSI feedback refers to the value of the rank indication RI.
Optionally, the UE limits the configuration of ri-distribution according to maxMIMO-Layers-BWP in the CSI feedback. The configuration of the Restriction ri-distribution includes: the maximum rank indication RI allowed for feedback in RI-feedback does not exceed maxMIMO-relays-BWP-1. Wherein the rank indication RI is numbered from 0. For example, if maxMIMO-Layers-bwp=2, the maximum rank indication RI allowed for feedback in RI-feedback takes a value of 0 or 1. Then ri-distribution may be binary 0011 or 0001.
Optionally, the UE determines the maximum number of Layers in CSI feedback according to min (max mimo-Layers-BWP (RI-maximum rank indication RI indicated by RI-distribution +1)) in CSI feedback. For example, if maxMIMO-Layers-bwp=4, the maximum rank indication RI allowed to be fed back in RI-feedback takes a value of 1, and the maximum number of Layers in CSI feedback for the UE is 2. Optionally, the maximum number of layers in CSI feedback refers to the 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 reporting amount reportquality when the UE reports CSI is configured to cri-RI-CQI, the maximum rank value allowed in the portandexfor 8Ranks of the UE does not exceed maxmmo-Layers-BWP. For example, if maxMIMO-Layers-bwp=2, then portindixfor 8Ranks may take on values { portIndex1, portIndex2}.
Optionally, when the reporting amount reporting quality when the UE reports CSI is configured to cri-RI-CQI, the UE determines the maximum number of Layers when CSI feedback is performed by itself according to min (maximum rank value allowed in maxmmo-Ranks-BWP, portIndexFor Ranks). For example, if maxMIMO-Layers-bwp=2 and portlndexfor 8Ranks takes portIndex4, the maximum number of Layers for the UE to perform CSI feedback is 2. Optionally, the maximum value of the rank indication RI fed back by the UE is 2 (note: here counting from 1).
Optionally, the base station configures the rank Restriction ri-allocation 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 maxmmo-Layers-BWP for BWP. Wherein the maximum rank indication RI value allowed to be fed back in RI-distribution does not exceed maxMIMO-Layers-BWP-1. Wherein the rank indication RI is numbered from 0. For example, if maxMIMO-Layers-bwp=2, the maximum rank indication RI allowed for feedback in RI-feedback takes a value of 0 or 1. Then ri-distribution may be binary 0011 or 0001.
Optionally, the base station configures portIndexfor8Ranks of the user equipment according to a maximum MIMO layer number maxMIMO-Layers-BWP of the BWP level configured for the user equipment. When the reportquality of the base station to the user equipment is configured to 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 the value { portIndex1, portIndex2, portIndex4, portIndex8}. For example, if maxMIMO-Layers-bwp=2, then portindixfor 8Ranks may take on values { portIndex1, portIndex2}.
After receiving the CSI, the base station knows that the UE uses the CSI-RS resources with the previously defined port numbers (e.g., port numbers 0 and 1) to obtain the measurement result. Thus, possible misunderstanding between the base station and the UE is avoided, and data transmission between the base station and the UE can be more reliable, so that power can be saved. In addition, as UE reduces measurement of CSI-RS resources with port numbers of 2-7, power consumption can be reduced.
In one embodiment, the power saving channel (i.e., DCI with CRC scrambled by PS-RNTI) is indicated in the present application. The power saving channel is a PDCCH scrambled by the PS-RNTI or DCI format 3-0. The base station configures some resources and parameters to the UE.
The channel state information reports configuration information CSI-ReportConfig. Optionally, the CSI-ReportConfig includes resources of CSI-RS for measuring channel state information, port index PortIndexFor8Ranks for rank 8. Optionally, the value range of portIndexFor8Ranks is { 8-port index portIndex8, 4-port index portIndex4, 2-port index portIndex2, single-port index portIndex1}.

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.
The power saving channels (i.e., downlink control information scrambled by the power saving radio network temporary identity(s) CRC; DCI with CRC scrambled by PS-RNTI; DCI Format 3_0; carried by the PDCCH). The power-saving 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 for other UEs.
The UE may report the maximum MIMO layer number maxmmo-Layers-Desired to the UE of the base station. Only one such value (e.g., maxmmo-layered-desired=2) can be reported by one UE at a time.
Secondly, the base station transmits CSI-RS of several ports. For example, a 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 3 rd 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 reporting CSI.
And then, the base station transmits a power-saving channel. Indicating how many CSI-RS ports the UE needs to measure.
The UE then determines the number of CSI-RS resources (here equal to the number of ports) to measure 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 the maxMIMO-Layers-ServerCell CSI-RS ports. If maxMIMO-Layers-ServerCell is equal to 4, then the UE needs to measure 4 CSI-RS ports. Alternatively, the UE may select the 4 CSI-RS resources with the smallest port number for measurement. That is, CSI-RS resources with port numbers 0-3 are selected. And then, the UE reports the CSI according to the measurement result.
Optionally, the UE determines the number of CSI-RS resources to measure by itself (here equal to the number of ports) 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 1, the UE needs to measure the maxMIMO-dyes-BWP CSI-RS ports. If maxMIMO-dyes-BWP is equal to 2, the UE needs to measure 2 CSI-RS ports. Alternatively, the UE may select the 2 CSI-RS resources with the smallest port number for measurement. That is, 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 to measure by itself (here equal to the number of ports) from 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 for measurement. That is, 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 to measure by itself (here equal to the number of ports) from the wake-up bit of one bit of the power saving channel. For example, if the wakeup 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 for measurement. That is, 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 to measure by itself (here equal to the number of ports) from the wake-up bit of one bit of the power saving channel. For example, if the wakeup bit is 1, the UE needs to measure 4 CSI-RS ports. Alternatively, the UE may select the 4 CSI-RS resources with the smallest port number for measurement. That is, CSI-RS resources with port numbers 0-3 are selected. And then, the UE reports the CSI according to the measurement result.
Optionally, the UE determines the number of CSI-RS resources to be measured by itself (here equal to the number of ports) according to a function specified by a wake-up bit of one bit of the power saving channel. For example, if the function specified by the wake-up bit is "not wake-up", 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 for measurement. That is, 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 to be measured by itself (here equal to the number of ports) according to a function specified by a wake-up bit of one bit of the power saving 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 the 4 CSI-RS resources with the smallest port number for measurement. That is, 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 with the previously defined port numbers (e.g., port numbers 0 and 1) to obtain the measurement result. Thus, possible misunderstanding between the base station and the UE is avoided, and data transmission between the base station and the UE can be more reliable, so that power can be saved. In addition, as UE reduces measurement of CSI-RS resources with port numbers of 2-3, power consumption can be reduced.
Alternatively, the UE may report maxMIMO-layered-Desired based on its own evaluation. After receiving the maxMIMO-latches-Desired, the base station synthesizes the maxMIMO-latches-Desired values reported by each UE, and if most UEs report maxMIMO-latches-desired=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 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, an ideal backhaul (or non-ideal backhaul) connection (with transmission delay being considered) may be used between different TRPs.
First, the base station configures some resources and parameters to the UE.
Configuration information of transmitting and receiving points. Such as the ID of the TRP, the set of control resources CORESET available to the TRP (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 usage may be shared by scrambling codes corresponding to IDs of different TRPs. Alternatively, the usage may be shared through antenna ports corresponding to IDs of different TRPs. Alternatively, the usage may be shared through DCI formats corresponding to IDs of different TRPs. Alternatively, the usage may be shared by control channel element CCE offsets corresponding to IDs of different TRPs.
A power saving channel (i.e., DCI with CRC scrambled by PS-RNTI).
The TRP of single DCI or Multiple DCI that the UE expects operates MTRP-Multiple-DCI-Desired. MTRP-Multiple-DCI-Desired is True, then the TRP operation of the UE expecting Multiple DCIs is identified; otherwise the UE expects TRP operation of single DCI.
Second, the base station transmits a power save channel to the UE. Alternatively, the base station may transmit the power save channel to the UE with one or more TRPs. For example, 2 power saving channels are transmitted to the UE with 2 TRPs. Alternatively, the contents of the 2 power saving channels may be different. Optionally, the 2 power save channels carry an ID of TRP. Alternatively, the contents of these 2 power saving channels are identical except for the ID of TRP. Optionally, if the UE receives a power saving channel with inconsistent content from different TRPs, ignoring all the power saving channels; alternatively, the UE remains in this case (e.g., not awake; remains in sleep; remains in DRX-OFF) as it is. Optionally, if the UE receives a power saving channel whose contents are inconsistent except for the ID of the TRP from the different TRP, ignoring all the power saving channels; alternatively, the UE remains in this case (e.g., not awake; remains in sleep; remains in DRX-OFF) as it is.
Alternatively, 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 indicates a UE in the power save channel, the number of CORESETs for TRP is 2, then the UE should use the CORESET ID not exceeding the indicated value (here 2). In this case, the UE needs a CORESET ID of 0 or 1 for blind detection. That is, the UE does not use CORESET with blind detection ID of 2-4, thereby saving power.
Then, the UE expects TRP operation MTRP-Multiple-DCI-Desired of single DCI or Multiple DCI for the UE reported by the base station. For example, if the data amount of the service currently operated by the UE is small, the UE may report MTRP-Multiple-DCI-Desired as False.
Thereafter, the base station receives the MTRP-Multiple-DCI-Desired reported by the UE. If the MTRP-Multiple-DCI-Desired is False, the base station may configure the UE with TRP operation of a single DCI or a single TRP. Since the UE reduces the reception of TRP or reduces the reception of DCI, the UE may save a part of power.
