Description

Channel state information report transmission

Background

Channel State Information (CSI) may be used to facilitate a communication link between wireless nodes, e.g., between a User Equipment (UE) and a Base Station (BS). For example, the BS (and/or one or more other BSs) may provide the UE with one or more signals requesting CSI, and the UE may provide the BS (and/or one or more other BSs) with the one or more CSI. One signal from the BS requesting CSI may be associated with one type, and another signal from the BS requesting CSI may be associated with another type. To maintain one or more communication links, the UE may need to calculate and/or generate CSI according to the type associated with the corresponding signal. However, the UE may have limited resources and/or limited capabilities.

Detailed Description

The subject matter now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific example embodiments. This description is not intended to be an extensive or detailed discussion of known concepts. Details that are generally known to those of ordinary skill in the relevant art may have been omitted or may be processed in a summarized manner.

The following subject matter may be embodied in various forms, such as methods, devices, components, and/or systems. Thus, this subject matter is not intended to be construed as limited to any of the example embodiments set forth herein. Rather, the example embodiments are provided for illustration only. Such embodiments may take the form of, for example, hardware, software, firmware, or any combination thereof.

One or more computing devices and/or techniques are provided for facilitating transmission of Channel State Information (CSI) reports. For example, a User Equipment (UE) may connect (e.g., wirelessly communicate) to a network via a Base Station (BS) of the network. The BS may request one or more CSI reports from the UE. One or more CSI reports may be used, for example, to enable the BS to reliably and/or at high data rates communicate with the UE (e.g., by enhancing signals transmitted from the BS to the UE based on information in the CSI reports, etc.). The connection between the UE and the BS may involve sending multiple (e.g., a large number) of requests from the BS to the UE and/or multiple (e.g., a large number) of CSI reports from the UE to the BS. Some approaches that facilitate sending CSI reports at low overhead may result in the sending of time-ineffective data and/or inaccuracies (e.g., and thus provide for less reliable and/or lower data rate associated communication between the BS and the UE than is possible). Thus, in accordance with one or more techniques provided herein, transmission of CSI reports can be facilitated in a manner that balances the risk of using excessive overhead (e.g., with respect to available resources) and the desire to have time-efficient and/or accurate CSI reports in order to provide optimal communication between a BS (e.g., and/or one or more other BSs) and a UE (e.g., and/or one or more other UEs).

An example method 100A that facilitates transmission of CSI reports from a first node to a second node is illustrated in fig. 1A. The first node may be a UE and the second node may be a network and/or a BS. The first node may receive one or more reference signals from the second node. The first node may (e.g., be required to) send one or more CSI reports to the second node based on the one or more reference signals to maintain a connection (e.g., between the first node and the second node). The first node may determine and/or generate CSI content of the CSI report, e.g., rank indicator, Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI), and/or other content (e.g., required). Thus, at 105A, the first node determines a rank indicator. The rank indicator may indicate one or more parameters of the CSI report.

The first node may then determine parameters for CSI reporting based on the rank indicator, at 110A. For example, the rank indicator may indicate (e.g., a parameter including) an amount (e.g., number) of resources corresponding to the CSI report. Resources may be assigned (e.g., allocated) by the first node and/or the second node for generating the CSI report. Thus, the first node may determine a (e.g., total) number of resources for generating the CSI report based on the rank indicator. The number of resources may be fixed (e.g., defined). Alternatively and/or additionally, the number of resources may be configured (e.g., and/or adjusted) by the first node and/or the second node.

In some examples, the rank indicator may indicate (e.g., a parameter including) a first amount (e.g., number) of resources corresponding to a first portion of the CSI report. Resources (e.g., one or more) corresponding to the first portion may be assigned by the first node and/or the second node for generating the first portion. Thus, the first node may determine the first number of resources based on the rank indicator. In some examples, the first portion includes a rank indicator.

In some examples, the rank indicator may indicate (e.g., a parameter including) a second amount (e.g., number) of resources corresponding to a second portion of the CSI report. Resources (e.g., one or more) corresponding to the second portion may be assigned by the first node and/or the second node for generating the second portion. Thus, the first node may determine the second amount of resources based on the rank indicator. In some examples, the second portion includes PMI, CQI, and/or other content. Thus, the first number of resources and the second number of resources in combination (e.g., sum, product, etc.) may correspond to a payload size of the CSI report.

In some examples, the rank indicator may indicate (e.g., a parameter including) a third amount (e.g., number) of resources corresponding to a third portion of the CSI report. Resources (e.g., one or more) corresponding to the third portion may be assigned by the first node and/or the second node for generating the third portion. Thus, the first node may determine the third number of resources based on the rank indicator. The resources assigned to the third portion may be outside of the resources assigned to the first portion and/or the resources assigned to the second portion (e.g., and/or not assigned to the resources assigned to the first portion and/or the resources assigned to the second portion).

In some examples, the rank indicator may indicate at least one of a first number of resources, a second number of resources, a third number of resources, a number of resources to be used for generating CSI reports, and/or a combination of the first number of resources, the second number of resources, the third number of resources, and/or a number of resources to be used for generating CSI reports.

For example, the rank indicator may indicate a combination (e.g., sum, product, etc.) of the first number of resources and the second number of resources. Alternatively and/or additionally, the rank indicator may indicate a number of resources to be used for generating CSI reports. Thus, the first node may determine the third number of resources (e.g., to generate the third portion) by determining a difference between the (e.g., total) number of resources to be used to generate the CSI report and a combination of the first number of resources and the second number of resources.

In another example, the rank indicator may indicate a combination (e.g., sum, product, etc.) of the second number of resources and the third number of resources. Alternatively and/or additionally, the rank indicator may indicate the second number of resources. Thus, the first node may determine the third amount of resources (e.g., to generate the third portion) by determining a difference between the second amount of resources and a combination of the second amount of resources and the third amount of resources.

In another example, the rank indicator may indicate a combination (e.g., sum, product, etc.) of the second number of resources and the third number of resources. Alternatively and/or additionally, the rank indicator may indicate a third number of resources. Thus, the first node may determine the second amount of resources (e.g., to generate the second portion) by determining a difference between the third amount of resources and a combination of the second amount of resources and the third amount of resources.

In another example, the rank indicator may indicate a (e.g., total) number of resources to be used for generating the CSI report. Alternatively and/or additionally, the rank indicator may indicate the first number of resources. Thus, the first node may determine a combination (e.g., sum, product, etc.) of the second number of resources and the third number of resources (e.g., to generate the second portion and/or the third portion) by determining a difference between the number of resources used in generating the CSI report and the first number of resources.

In some examples, the CSI report may correspond to the time domain. Accordingly, the resources of the CSI report (e.g., the resources assigned to the first portion, the resources assigned to the second portion, and/or the resources assigned to the third portion) may include symbols. The symbols may include Orthogonal Frequency Division Multiplexing (OFDM) symbols.

In some examples, the CSI report may correspond to the frequency domain. Accordingly, the resources of the CSI report (e.g., the resources assigned to the first portion, the resources assigned to the second portion, and/or the resources assigned to the third portion) may include resource blocks and/or subcarriers.

In some examples, the rank indicator may indicate (e.g., a parameter including) a number of repetitions of information of the CSI report. Thus, the first node may determine the number of repetitions of the information based on the rank indicator. The number of repetitions of the information may correspond to the number of times the information is to be repeated within a CSI report (e.g., one or more portions of a CSI report). For example, the number of repetitions of the information may correspond to the number of times information of one portion (e.g., the second portion) of the CSI report is to be repeated within another portion (e.g., the third portion) of the CSI report.

The first node may determine the number of repetitions of the information based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the first value of the rank indicator may correspond to one transmission of information of a portion (e.g., the second portion) of the CSI report and/or zero repetitions of the information of the portion. Alternatively and/or additionally, the second value of the rank indicator may correspond to two transmissions of the portion of information and/or one repetition of the portion of information. Alternatively and/or additionally, the third value may correspond to three transmissions of the portion of information and/or two repetitions of the portion of information.

In some examples, the rank indicator may indicate (e.g., a parameter including) a code rate of the CSI report. Thus, the first node may determine the code rate based on the rank indicator. In some examples, the CSI report does not include the third portion. The code rate may correspond to (e.g., be used for processing) the second portion (e.g., of the CSI report).

The first node may determine the code rate based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the first value may correspond to a first code rate. Alternatively and/or additionally, the second value may correspond to the second code rate. Alternatively and/or additionally, the third value may correspond to a third code rate.

In some examples, the rank indicator may indicate (e.g., parameters including) a modulation scheme (e.g., Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), M-quadrature amplitude modulation (M-QAM), etc.) of the CSI report. Thus, the first node may determine the modulation scheme based on the rank indicator. In some examples, the CSI report does not include the third portion. The modulation scheme may correspond to (e.g., be used for processing) the second portion (e.g., of the CSI report).

The first node may determine the modulation scheme based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the first value may correspond to a first modulation scheme (e.g., QPSK, BPSK, M-QAM, etc.). Alternatively and/or additionally, the second value may correspond to a second modulation scheme. Alternatively and/or additionally, the third value may correspond to a third modulation scheme.

At 115A, the first node may generate a CSI report based on the parameter and/or the rank indicator. For example, the first node may generate a first portion (e.g., of a CSI report) that includes a rank indicator. Accordingly, the first node may map the first portion (e.g., including the rank indicator) to resources assigned to the first portion. Alternatively and/or additionally, the first node may generate a first portion comprising a rank indicator and/or a Relative Power Indicator (RPI). For example, the rank indicator and/or the RPI may be jointly encoded. Accordingly, a first portion (e.g., including a rank indicator and/or RPI) is mapped to resources assigned to the first portion. In some examples, the RPI may indicate at least one of a (e.g., total) number of resources, a first number of resources, a second number of resources, and/or a third number of resources, and/or a combination of the first number of resources, the second number of resources, the third number of resources, and/or the (e.g., total) number of resources. In some examples, the first node may map (e.g., at least a portion of) the PMI (e.g., in addition to the RPI) to resources corresponding to the second portion.

Alternatively and/or additionally, the first node may generate the second portion (e.g., of the CSI report) based on a second number of resources (e.g., corresponding to the second portion). The first node may map (e.g., at least some) CSI content (e.g., PMI, CQI, etc.) to the resources assigned to the second portion (e.g., based on the second number of resources). Alternatively and/or additionally, the first node may generate the first sub-portion including the RPI in the second portion. Thus, a first sub-portion of the second portion (e.g., including the RPI) may be mapped to resources assigned to the first sub-portion of the second portion. In some examples, the RPI may indicate at least one of parameters including a number of resources of the second sub-portion of the second portion, a code rate of the second sub-portion of the second portion, and/or a modulation scheme of the second sub-portion of the second portion. In some examples, the first node may map (e.g., at least a portion of) the PMI (e.g., in addition to the RPI) to resources corresponding to a second sub-portion of the second portion.

In some examples, the first node may generate the third portion based on the number of repetitions. For example, the first node may generate a third portion that includes one or more repetitions of the information of the second portion. Thus, the first node may map (e.g., based on the number of repetitions) repetitions of (e.g., at least some) CSI content (e.g., PMI, CQI, etc.) to the resources assigned to the third portion.

In some examples, the first node may generate the second portion based on a code rate (e.g., indicated by a rank indicator) of (e.g., corresponding to) the second portion. Alternatively and/or additionally, the first node may generate the second portion based on a modulation scheme (e.g., corresponding to the second portion) (e.g., indicated by the rank indicator). For example, the first node may generate the second portion using the first code rate and/or using a QPSK modulation scheme. Alternatively and/or additionally, the first node may generate the second portion using the second code rate and/or using a BPSK modulation scheme.

In some examples, the CSI report may correspond to the time domain. Thus, the resources in the CSI report may correspond to symbols. In some examples, the first node may map (e.g., based on instructions received from the second node) the first portion to a fixed (e.g., defined) location of a symbol configured (e.g., modified) by the first node and/or the second node. For example, the first node may map the first portion to one or more symbols corresponding to a first (e.g., beginning, middle, end, etc.) portion of the slot. Alternatively and/or additionally, the first node may map the first portion to one or more symbols that are adjacent (e.g., subsequent to and/or adjacent) to one or more symbols assigned to (e.g., and/or including) (e.g., transmitted by and/or received from) a reference signal(s) (e.g., transmitted by and/or received from the second node).

In some examples, the first node may map the second portion to one or more symbols that are prior to (e.g., and/or preceding, etc.) one or more symbols of the third portion. Alternatively and/or additionally, the first node may map the second portion to one or more symbols subsequent to (e.g., and/or subsequent to) the one or more symbols of the third portion.

In some examples, the CSI report may correspond to the frequency domain. Thus, the resources in the CSI report may comprise resource blocks and/or subcarriers. In some examples, the first node may map (e.g., based on instructions received from the second node) the first portion to a fixed location of resource blocks (e.g., and/or subcarriers) configured (e.g., modified) by the first node and/or the second node. For example, the first node may map the first portion to one or more resource blocks and/or subcarriers of the resource block and/or subcarrier having the lowest frequency of the resources assigned (e.g., allocated) for generating the CSI report. The resource block and/or subcarrier may be determined to have the lowest frequency based on having a frequency below a frequency threshold and/or having a frequency below a ranking threshold when ordered with respect to frequency of the resource block and/or subcarrier.

Alternatively and/or additionally, the first node may map the first portion to one or more resource blocks and/or subcarriers of the resource block and/or subcarrier having the highest frequency of the resources assigned (e.g., allocated) for generating CSI reports. The resource blocks and/or subcarriers may be determined to have the highest frequency based on having a frequency above a frequency threshold and/or having a frequency above a ranking threshold when ordered with respect to frequency of the resource blocks and/or subcarriers.

Alternatively and/or additionally, the first node may map the first portion to one or more resource blocks and/or sub-carriers having frequencies between the lowest frequency and the highest frequency. Alternatively and/or additionally, the first node may map the first portion to one or more resource blocks and/or subcarriers that are adjacent to (e.g., subsequent to and/or adjacent to) one or more resource blocks (e.g., and/or subcarriers) assigned to (e.g., and/or including) the reference signal.

In some examples, the first node may map the second portion to one or more resource blocks and/or subcarriers having a lower frequency than one or more resource blocks (e.g., and/or subcarriers) of the third portion. Alternatively and/or additionally, the first node may map the second portion to one or more resource blocks (e.g., and/or subcarriers) having a higher frequency than the frequency of the one or more symbols of the third portion.

At 120A, the first node sends a CSI report to the second node. In some examples, a first node sends one or more CSI reports to a second node in one or more time slots (e.g., and/or time slots). In some examples, there may be a time interval (e.g., of 5 ms) between the first slot and the second (e.g., adjacent) slot. In some examples, the first node sends the CSI report in a (e.g., single) time slot.

In some examples, a first node is configured to transmit one or more CSI reports in a multi-transceiver point (TRP) transmission configuration (e.g., in one or more time slots). For example, the first plurality of resources may be assigned to (e.g., and/or include) a first portion of the first CSI report and/or a first portion of the second CSI report. In some examples, the second plurality of resources may be assigned to (e.g., and/or include) the second portion of the first CSI report and/or the second portion of the second CSI report. In some examples, the third plurality of resources may be assigned to (e.g., and/or include) a third portion of the first CSI report and/or a third portion of the second CSI report.

In some examples, the first portion of the first CSI report includes a rank indicator indicating the second portion of the first CSI report and/or one or more parameters of the second portion of the first CSI report. In some examples, the first portion of the second CSI report includes a rank indicator indicating one or more parameters of a third portion of the second CSI report and/or a second portion of the second CSI report. In some examples, the first portion of the first CSI report and/or the first portion of the second CSI report are jointly encoded within the first plurality of resources. In some examples, the second portion of the first CSI report and/or the second portion of the second CSI report are jointly encoded within the second plurality of resources. In some examples, the third portion of the first CSI report and/or the third portion of the second CSI report are jointly encoded within a third plurality of resources. In some examples, the first node may transmit the first plurality of resources to the master TRP or plurality of TRPs in the first time slot and the second plurality of resources to the master TRP or plurality of TRPs in the second time slot.

An example method 100B that facilitates transmission of CSI reports from a first node to a second node is illustrated in fig. 1B. The first node may be a UE and the second node may be a network and/or a BS. The first node may receive one or more reference signals from the second node. The first node may (e.g., be required to) send one or more CSI reports to the second node based on the one or more reference signals in order to maintain a connection (e.g., between the first node and the second node). Thus, at 105B, the first node may receive a (e.g., reference) signal from the second node. In some examples, the signal may include (e.g., indicate) a number of repetitions of the information (e.g., as configured by the second node).

The first node may (e.g., be required to) determine and/or generate CSI content, such as rank indicator, PMI, CQI, and/or other content, for the CSI report based on the signal. Thus, at 110B, the first node may determine a number of repetitions of information of the CSI report based on the signal. Alternatively and/or additionally, the first node may determine a rank indicator indicating one or more parameters of the CSI report.

In some examples, the number of repetitions of the information may correspond to the number of times the information is to be repeated within a CSI report (e.g., one or more portions of a CSI report). For example, the number of repetitions of the information may correspond to a number of times a rank indicator of the CSI report is to be repeated within a portion (e.g., a first portion, a second portion, a third portion, etc.) of the CSI report.

Thus, at 115B, the first node may generate a CSI report based on the number of repetitions of the information. In some examples, the first node may generate the first portion based on a number of repetitions. For example, the first node may generate a first portion comprising one or more repetitions of a rank indicator. Accordingly, the first node may map the first portion (e.g., including the rank indicator) to resources assigned to the first portion.

Alternatively and/or additionally, the first node may generate the second portion (e.g., of the CSI report) based on CSI content (e.g., at least some) of the CSI report, e.g., PMI, CQI, and/or other content. The first node may map the CSI content to resources assigned to the second portion. Thus, at 120B, the first node may send a CSI report to the second node. In some examples, the first node sends the CSI report in a (e.g., single) time slot.

Alternatively and/or additionally, the first node may generate a first portion comprising a rank indicator and/or an RPI. For example, the rank indicator and/or the RPI may be jointly encoded. Accordingly, a first portion (e.g., including a rank indicator and/or RPI) is mapped to resources assigned to the first portion. In some examples, the RPI may indicate at least one of a (e.g., total) number of resources, a first number of resources, a second number of resources, and/or a third number of resources, and/or a combination of the first number of resources, the second number of resources, the third number of resources, and/or the (e.g., total) number of resources. In some examples, the first node may map (e.g., at least a portion of) the PMI (e.g., in addition to the RPI) to resources corresponding to the second portion.

An example method 100C that facilitates transmission of CSI reports from a first node to a second node is shown in fig. 1C. The first node may be a UE and the second node may be a network and/or a BS. The first node may receive one or more reference signals from the second node. The first node may (e.g., be required to) send one or more CSI reports to the second node based on the one or more reference signals in order to maintain a connection (e.g., between the first node and the second node). The first node may determine and/or generate CSI content, e.g., rank indicator, PMI, CQI, and/or other content, of the CSI report (e.g., required). Thus, at 105C, the first node determines a rank indicator. The rank indicator may indicate one or more parameters of the CSI report.

The first node may then determine parameters for CSI reporting based on the rank indicator, at 110C. For example, the first node may determine a (e.g., total) number of resources for generating the CSI report based on the rank indicator. Alternatively and/or additionally, the first node may determine a first amount (e.g., number) of resources corresponding to the first portion of the CSI report based on the rank indicator. In some examples, the first portion includes a rank indicator. Alternatively and/or additionally, the first node may determine a second amount (e.g., number) of resources corresponding to a second portion of the CSI report based on the rank indicator. In some examples, the second portion includes PMI, CQI, and/or other content. Alternatively and/or additionally, the first node may determine a third amount (e.g., number) of resources corresponding to a third portion of the CSI report.

In some examples, the CSI report may correspond to the time domain. Accordingly, the resources of the CSI report (e.g., resources corresponding to the first portion, resources corresponding to the second portion, and/or resources corresponding to the third portion) may include symbols. The symbols may comprise OFDM symbols.

In some examples, the CSI report may correspond to the frequency domain. Accordingly, the resources of the CSI report (e.g., the resources corresponding to the first portion, the resources corresponding to the second portion, and/or the resources corresponding to the third portion) may include resource blocks and/or subcarriers.

In some examples, the rank indicator may indicate (e.g., a parameter including) a number of repetitions of information of the CSI report. Thus, the first node may determine the number of repetitions of the information based on the rank indicator. In some examples, the rank indicator may indicate (e.g., a parameter including) a code rate of the CSI report. Thus, the first node may determine the code rate based on the rank indicator. In some examples, the rank indicator may indicate (e.g., parameters including) a modulation scheme of the CSI report. Thus, the first node may determine the modulation scheme based on the rank indicator.

In some examples, the rank indicator may indicate (e.g., a parameter including) a format of the second portion of the CSI report (e.g., and/or the third portion of the CSI report). Thus, the first node may determine the format based on the rank indicator. The first node may determine the format based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the first value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) may correspond to a second portion of the CSI report using the short duration format (e.g., and/or a third portion of the CSI report). Alternatively and/or additionally, the second value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) may correspond to a second portion of the CSI report using the long-duration format (e.g., and/or a third portion of the CSI report).

At 115C, the first node may generate a first portion of a CSI report based on the rank indicator. For example, the first node may generate a first portion (e.g., of a CSI report) that includes a rank indicator. Accordingly, the first node may map the first portion (e.g., including the rank indicator) to resources assigned to the first portion. Alternatively and/or additionally, the first node may generate a first portion comprising a rank indicator and/or an RPI. For example, the rank indicator and/or the RPI may be jointly encoded. Thus, a first portion (e.g., including a rank indicator and/or RPI) is mapped to resources corresponding to the first portion.

Alternatively and/or additionally, at 120C, the first node may generate a second portion of the CSI report based on a parameter (e.g., a second number of resources corresponding to the second portion). The first node may map (e.g., at least some) CSI content (e.g., PMI, CQI, etc.) to resources corresponding to the second portion (e.g., based on the second number of resources).

In some examples, the first node may generate the third portion based on a number of repetitions (e.g., determined based on the rank indicator). For example, the first node may generate a third portion that includes one or more repetitions of the information. Thus, the first node may map one or more repetitions of the information to resources corresponding to the third portion (e.g., based on the number of repetitions).

At 120C, the first node transmits a first portion of the CSI report to the second node in the first time slot. In some examples, a first node sends one or more CSI reports to a second node in one or more time slots (e.g., and/or time gaps). In some examples, there may be a time interval (e.g., of 5 ms) between the first slot and the second (e.g., adjacent) slot. At 125C, the first node transmits a second portion of the CSI report to the second node in a second time slot.

Alternatively and/or additionally, the first node may be configured to transmit the rank indicator and/or the RPI in the first time slot. For example, the rank indicator and/or the RPI may be jointly encoded. Thus, the rank indicator and/or RPI is mapped to resources (e.g., corresponding to the first slot) assigned to the first portion. In some examples, the RPI may indicate at least one of a (e.g., total) number of resources, a first number of resources, a second number of resources, and/or a third number of resources, and/or a combination of the first number of resources, the second number of resources, the third number of resources, and/or the (e.g., total) number of resources. In some examples, the first node may map (e.g., at least a portion of) the PMI (e.g., in addition to the RPI) to resources corresponding to the second portion (e.g., corresponding to the second slot).

An example method 100D that facilitates transmission of CSI reports from a first node to a second node is illustrated in fig. 1D. The first node may be a UE and the second node may be a network and/or a BS. The second node may transmit one or more reference signals to the first node. The second node may receive one or more CSI reports from the first node based on the one or more reference signals. Thus, at 105D, the second node may receive a CSI report. The CSI report may include CSI content such as rank indicator, PMI, CQI, and/or other content.

Thus, at 110D, the second node determines (e.g., identifies, extracts, etc.) a rank indicator based on (e.g., from) the CSI report. The rank indicator may indicate one or more parameters of the CSI report. Thus, at 115D, the second node may determine parameters for CSI reporting based on the rank indicator. For example, the second node may determine a (e.g., total) number of resources assigned to the CSI report based on the rank indicator. Alternatively and/or additionally, the second node may determine a first amount (e.g., number) of resources corresponding to the first portion of the CSI report based on the rank indicator. Alternatively and/or additionally, the second node may determine a second amount (e.g., number) of resources corresponding to a second portion of the CSI report based on the rank indicator. In some examples, the second portion includes PMI, CQI, and/or other content. Alternatively and/or additionally, the second node may determine a third amount (e.g., number) of resources corresponding to a third portion of the CSI report.

In some examples, the CSI report may correspond to the time domain. Accordingly, the resources of the CSI report (e.g., the resources corresponding to the second portion and/or the resources corresponding to the third portion) may include symbols. The symbols may comprise OFDM symbols.

In some examples, the CSI report may correspond to the frequency domain. Accordingly, the resources of the CSI report (e.g., the resources corresponding to the second portion and/or the resources corresponding to the third portion) may include resource blocks and/or subcarriers.

In some examples, the rank indicator may indicate (e.g., a parameter including) a number of repetitions of information of the CSI report. Thus, the second node may determine the number of repetitions of the information based on the rank indicator. In some examples, the rank indicator may indicate (e.g., a parameter including) a code rate of the CSI report. Thus, the second node may determine the code rate based on the rank indicator. In some examples, the rank indicator may indicate (e.g., parameters including) a modulation scheme of the CSI report. Thus, the second node may determine the modulation scheme based on the rank indicator.

In some examples, the second node may be based on one or more parameters of the rank indicator (e.g., a second number of resources corresponding to the second portion, a third number of resources corresponding to the third portion, a code rate, a modulation scheme, a number of repetitions of information, etc.). For example, the second node may generate, extract, decrypt, and/or interpret information (e.g., from the CSI report and/or one or more other CSI reports) based on the one or more parameters. The second node may then generate a data signal based on the CSI report. Thus, the second node may transmit the data signal to the first node.

An example method 100E that facilitates transmission of CSI reports from a first node to a second node is illustrated in fig. 1E. The first node may be a UE and the second node may be a network and/or a BS. The second node may transmit one or more reference signals to the first node. The second node may receive one or more CSI reports from the first node based on the one or more reference signals. Thus, at 105E, the second node may determine a (e.g., desired) number of repetitions of information of the CSI report.

In some examples, the number of repetitions of the information may correspond to the number of times the information is to be repeated within a CSI report (e.g., one or more portions of a CSI report). For example, the number of repetitions of the information may correspond to a number of times a rank indicator of the CSI report is to be repeated within a portion (e.g., a first portion) of the CSI report.

In some examples, the first value of the number of information repetitions may correspond to one transmission of a rank indicator and/or zero repetitions of the rank indicator. Alternatively and/or additionally, the second value of the rank indicator may correspond to two transmissions of the rank indicator and/or one repetition of the rank indicator. Alternatively and/or additionally, the third value may correspond to three transmissions of the rank indicator and/or two repetitions of the rank indicator. More values may correspond to more transmissions and/or repetitions of the rank indicator.

At 110E, the second node may send a number of repetitions of the information of the CSI report (e.g., an indication of the number of repetitions of the information of the CSI report) to the first node. In some examples, the second node may send a number of repetitions of the information within the reference signal. Thus, the first node may process the reference signal and/or send a CSI report to the second node based on the reference signal. At 115E, the second node may receive a CSI report. The CSI report may include the number of repetitions of the rank indicator corresponding to the number of repetitions of the information. The second node may then process the CSI report and/or generate a data signal based on the CSI report. For example, the second node may generate, extract, decrypt, and/or interpret information (e.g., from the CSI report and/or one or more other CSI reports) based on the rank indicator and/or the number of repetitions of the information. The second node may then transmit the data signal to the first node.

An example method 100F that facilitates transmission of CSI reports from a first node to a second node is shown in fig. 1F. The first node may be a UE and the second node may be a network and/or a BS. The second node may transmit one or more reference signals to the first node. The second node may receive one or more CSI reports from the first node based on the one or more reference signals. Thus, at 105F, the second node may receive a first portion of the CSI report including the rank indicator in the first time slot.

The rank indicator may indicate one or more parameters of the CSI report. Thus, at 110F, the second node may determine parameters for CSI reporting based on the rank indicator. For example, the second node may determine a (e.g., total) number of resources assigned to the CSI report based on the rank indicator. Alternatively and/or additionally, the second node may determine a second amount (e.g., number) of resources corresponding to a second portion of the CSI report based on the rank indicator. In some examples, the second portion includes PMI, CQI, and/or other content. Alternatively and/or additionally, the second node may determine a third amount (e.g., number) of resources corresponding to a third portion of the CSI report.

In some examples, the CSI report may correspond to the time domain. Thus, the resources of the CSI report may comprise symbols. The symbols may comprise OFDM symbols. In some examples, the CSI report may correspond to the frequency domain. Thus, the resources of the CSI report may comprise resource blocks and/or subcarriers.

In some examples, the rank indicator may indicate (e.g., a parameter including) a format of the second portion of the CSI report. Thus, the second node may determine the format based on the rank indicator. The first node may determine the format based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node. In some examples, the first value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) may correspond to a second portion of the CSI report using the short duration format (e.g., and/or a third portion of the CSI report). Alternatively and/or additionally, the second value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) may correspond to a second portion of the CSI report using the long-duration format (e.g., and/or a third portion of the CSI report).

At 115F, the second wireless node receives a second portion of the CSI report in a second time slot. In some examples, the second node may process the second portion of the CSI report based on one or more parameters of the rank indicator (e.g., a second number of resources corresponding to the second portion, a code rate, a modulation scheme, a format, etc.). For example, the second node may generate, extract, decrypt, and/or interpret (e.g., from the CSI report and/or one or more other CSI reports) information based on one or more parameters (e.g., repetition, code rate, modulation scheme, format, etc.). The second node may then generate a data signal based on the CSI report. Thus, the second node may transmit the data signal to the first node.

Fig. 2 illustrates an example of a system 200 that facilitates transmission of a CSI report from a first node 210 (e.g., a UE) to a second node 205 (e.g., a network) by the system 200. In some examples, the second node 205 may transmit the reference signal 225 to the first node 210. Alternatively and/or additionally, the first node 210 may determine (e.g., and/or be required to) generate (e.g., based on the reference signal 225) a CSI report 215 including CSI content, such as rank indicator, PMI, CQI, and/or other content. Thus, the first node 210 may determine the rank indicator. In some examples, the rank indicator indicates one or more parameters (e.g., a first number of resources corresponding to a first portion of CSI report 215, a second number of resources corresponding to a second portion of CSI report 215, a third number of resources corresponding to a third portion of CSI report 215, a code rate, a modulation scheme, a number of repetitions of information, etc.).

In some examples, the first node 210 may generate the CSI report 215 based on one or more parameters. For example, the first node 210 may generate a first portion of CSI report 215 that includes a rank indicator. Accordingly, the first node 210 may map the first portion (e.g., including the rank indicator) to resources assigned to the first portion. Alternatively and/or additionally, the first node 210 may generate a first portion comprising a rank indicator and/or an RPI. Accordingly, a first portion (e.g., including a rank indicator and/or RPI) is mapped to resources corresponding to the first portion.

Alternatively and/or additionally, the first node 210 may generate a second portion of the CSI report 215, and/or the first node 210 may map (e.g., based on a second number of resources) CSI content (e.g., at least some) to resources corresponding to the second portion (e.g., PMI, CQI, etc.).

In some examples, the first node 210 may generate the third portion of the CSI report 215 based on the number of repetitions of the information. For example, the first node 210 may generate a third portion that includes one or more repetitions of the information. Thus, the first node may map one or more repetitions of the information to resources corresponding to the third portion (e.g., based on the number of repetitions of the information).

The first node 210 may then send the CSI report 215 to the second node 205. The second node 205 may receive the CSI report 215. In some examples, the second node 205 may determine (e.g., extract, identify, etc.) the rank indicator based on the CSI report. Alternatively and/or additionally, the second node 205 may determine one or more parameters based on the rank indicator. The second node 205 may then process the CSI report 215 based on the one or more parameters. The second node 205 may then generate a data signal 220 based on the CSI report. Thus, the second node may send the data signal 220 to the first node 210.

Fig. 3 illustrates an example of a system 300 that facilitates transmission of a CSI report from a first node 310 (e.g., a UE) to a second node 305 (e.g., a network). In some examples, the first node 310 may determine (e.g., and/or) generate (e.g., based on reference signals received from the second node 305) a CSI report including CSI content, such as a rank indicator, PMI, CQI, and/or other content (e.g., based on reference signals received from the second node 305). Thus, the first node 310 may determine the rank indicator. In some examples, the rank indicator indicates one or more parameters (e.g., a first number of resources corresponding to a first portion of CSI report 315, a second number of resources corresponding to a second portion of CSI report 320, a code rate, a modulation scheme, a number of repetitions of information, a format, etc.).

In some examples, the first node 310 may generate the CSI report based on one or more parameters. For example, the first node 310 may generate a first portion of the CSI report 315 that includes a rank indicator. Accordingly, the first node 310 may map a first portion (e.g., including a rank indicator) of the CSI report 315 to resources assigned to the first portion of the CSI report 315. Alternatively and/or additionally, the first node 310 may generate a first portion comprising a rank indicator and/or an RPI. Accordingly, a first portion (e.g., including the rank indicator and/or RPI) of the CSI report 315 is mapped to resources corresponding to the first portion.

Alternatively and/or additionally, the first node 310 may generate a second portion of the CSI report 320, and/or the first node 310 may map (e.g., based on a second number of resources) CSI content (e.g., at least some) to resources corresponding to the second portion of the CSI report 320 (e.g., PMI, CQI, etc.).

The first node 310 may transmit a first portion of the CSI report 315 to the second node 305 in a first time slot. The first node 310 may transmit the second portion of the CSI report 320 to the second node 305 in a second time slot. Alternatively and/or additionally, the second node 305 may receive the first portion of the CSI report 315 and may determine one or more parameters based on the rank indicator. The second node 305 may (e.g., then) receive the second portion of the CSI report 320. Thus, the second node 305 may process the second portion of the CSI report 305 based on one or more parameters. The second node 305 may then generate a data signal 325 based on the CSI report. Thus, the second node may send the data signal 325 to the first node 310.

Fig. 4 illustrates an example of a system 400 that facilitates sending a CSI report from a first node 410 (e.g., a UE) to a second node 405 (e.g., a network). The first node may (e.g., be required to) determine (e.g., and/or) CSI content, such as rank indicator, PMI, CQI, and/or other content, that generated CSI report 420. The second node 405 may determine the number of repetitions of the information 415. In some examples, the number of repetitions of information 415 may correspond to the number of times the information is to be repeated within CSI report 420 (e.g., one or more portions of CSI report 420). For example, the number of repetitions of information 415 may correspond to the number of times a rank indicator of CSI report 420 is to be repeated within a portion (e.g., a first portion, a second portion, etc.) of CSI report 420.

The second node 405 may send the first node 410 a number of repetitions of the information 415 (e.g., an indication of the number of repetitions of the information 415). In some examples, the second node 405 may send the number of repetitions of the information 415 within the reference signal. Thus, the first node 410 may receive the number of repetitions of the information 415.

The first node 410 may generate a CSI report 420 based on the number of repetitions of the information 415. In some examples, the first node 410 may generate a CSI report 420 including the number of repetitions of the rank indicator based on the number of repetitions of the information 415. The first node 410 may then send the CSI report 420 to the second node 405. The second node 405 may then process the CSI report 420 (e.g., based on the number of repetitions of the information 415) and/or generate a data signal 425 based on the CSI report 420. The second node 405 may then send a data signal 425 to the first node 410.

Fig. 5 shows a diagram 500 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the time domain. Thus, the resources in the CSI report may correspond to symbols. The uplink control channel may include a (e.g., total) number (e.g., number) of (e.g., OFDM) symbols (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) symbols. The first region 505 may include a first portion of a CSI report including a rank indicator. The first region 505 may include a first number (e.g., one or more) of symbols.

The number of regions (e.g., remaining) may be determined based on applying a predetermined rule to the value of the rank indicator (e.g., and/or the number of remaining symbols other than the first number of symbols within the first region 505). The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node (e.g., UE) and/or the second node (e.g., BS) (e.g., based on instructions received from the second node).

In some examples, the value of the rank indicator is compared to one or more thresholds. For example, a rank indicator having a first value less than or equal to (e.g., and/or greater than or equal to) a first threshold may correspond to an uplink control channel comprising two regions. Alternatively and/or additionally, a rank indicator having a second value less than or equal to (e.g., and/or greater than or equal to) a second threshold may correspond to an uplink control channel comprising three regions. Alternatively and/or additionally, a rank indicator having a third value less than or equal to (e.g., and/or greater than or equal to) a third threshold may correspond to an uplink control channel comprising four regions. Rank indicators having other values less than or equal to (e.g., and/or greater than or equal to) other thresholds may correspond to uplink control channels comprising other numbers of regions.

In some examples, the rank indicator may indicate a second number (e.g., number) of symbols (e.g., one or more) corresponding to a second region 510 that includes a second portion of the CSI report. In some examples, the second portion includes PMI, CQI, and/or other content. Thus, a combination (e.g., sum, product, etc.) of the first number of symbols and the second number of symbols may correspond to a payload size of the CSI report.

In some examples, the rank indicator may indicate a third number (e.g., number) of symbols (e.g., one or more) (e.g., remaining) corresponding to a third region 515 including a third portion of the CSI report.

Fig. 6 shows a diagram 600 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the time domain. Thus, the resources in the CSI report may correspond to symbols. The uplink control channel may include a (e.g., total) number (e.g., number) of (e.g., OFDM) symbols (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) symbols. The first region 605 may include a first portion of a CSI report including a rank indicator. The first region 605 may include a first number (e.g., one or more) of symbols.

The number of regions (e.g., remaining) may be determined based on applying a predetermined rule to the value of the rank indicator (e.g., and/or the number of remaining symbols other than the first number of symbols within the first region 605).

In some examples, the rank indicator may indicate a second number (e.g., number) of symbols (e.g., one or more) corresponding to a second region 610 that includes a second portion of the CSI report. In some examples, the second portion includes PMI, CQI, and/or other content. Thus, a combination (e.g., sum, product, etc.) of the first number of symbols and the second number of symbols may correspond to a payload size of the CSI report.

In some examples, the rank indicator may indicate a third number (e.g., number) of symbols (e.g., one or more) (e.g., remaining) corresponding to a third region 615 that includes a third portion of the CSI report.

The rank indicator may indicate the number of repetitions of the information. The number of repetitions of the information may correspond to the number of times the information is to be repeated within a CSI report (e.g., one or more portions of a CSI report). For example, the number of repetitions of the information may correspond to the number of times the information of the second portion of the CSI report corresponding to the second region 610 is to be repeated within the third portion of the CSI report corresponding to the third region 615. For example, the information of the second portion corresponding to the second region 610 may be repeated once within the third portion corresponding to the third region 615.

The number of repetitions of the information may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node (e.g., UE) and/or the second node (e.g., BS) (e.g., based on instructions received from the second node). In some examples, the first value of the rank indicator may correspond to one transmission of information of a portion (e.g., the second portion) of the CSI report and/or zero repetitions of the information of the portion. Alternatively and/or additionally, the second value of the rank indicator may correspond to two transmissions of the portion of information and/or one repetition of the portion of information. Alternatively and/or additionally, the third value of the rank indicator may correspond to three transmissions of the portion of information and/or two repetitions of the portion of information.

Fig. 7 shows a diagram 700 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the time domain. Thus, the resources in the CSI report may correspond to symbols. The uplink control channel may include a (e.g., total) number (e.g., number) of (e.g., OFDM) symbols (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) symbols. The first region 705 may include a first portion of a CSI report including a rank indicator. The second region 710 may include a second portion of the CSI report.

In some examples, the rank indicator may indicate (e.g., a parameter including) a code rate of the CSI report. Thus, the first node may determine the code rate based on the rank indicator. The code rate may correspond to (e.g., be used to generate and/or process) a second portion corresponding to the second region 710.

The code rate may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node (e.g., UE) and/or the second node (e.g., BS) (e.g., based on instructions received at the first node from the second node). In some examples, the rank indicator having the first value may correspond to a first code rate. Alternatively and/or additionally, the rank indicator having the second value may correspond to the second code rate. Alternatively and/or additionally, the rank indicator having the third value may correspond to a third code rate.

In some examples, the rank indicator may indicate (e.g., parameters including) a modulation scheme (e.g., QPSK, BPSK, M-QAM, etc.) of the CSI report. Thus, the first node may determine the modulation scheme based on the rank indicator. The modulation scheme may correspond to (e.g., be used to generate and/or process) the second portion corresponding to the second region 710.

The modulation scheme may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the rank indicator having the first value may correspond to a first modulation scheme (e.g., QPSK, BPSK, M-QAM, etc.). Alternatively and/or additionally, the rank indicator having the second value may correspond to the second modulation scheme. Alternatively and/or additionally, the rank indicator having the third value may correspond to a third modulation scheme

Fig. 8 shows a diagram 800 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the time domain. Thus, the resources in the CSI report may correspond to symbols. The uplink control channel may include a (e.g., total) number (e.g., number) of (e.g., OFDM) symbols (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) symbols. The first region 805 may include a first portion of a CSI report including a rank indicator.

In some examples, the number of repetitions of the information may be configured by the second node (e.g., BS) (e.g., via instructions, reference signals, etc. sent to the first node (e.g., UE)). The number of repetitions of the information may correspond to the number of times the information is to be repeated within the CSI report. For example, the number of repetitions of the information may correspond to the number of times the first portion corresponding to the first region 805 is to be repeated within the CSI report.

For example, the first portion corresponding to the first region 805 may be repeated three times (e.g., or any other number of times). In some examples, the second region 810 corresponding to one or more symbols adjacent to (e.g., adjacent to, after) the repeated one or more symbols of the first portion may include a second portion of the CSI report (e.g., it may not include the repeated information of the first region 805).

Fig. 9 shows a diagram 900 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the frequency domain. Thus, the resources in the CSI report may comprise resource blocks and/or subcarriers. The uplink control channel may include a (e.g., total) number (e.g., number) of resource blocks and/or subcarriers (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) resource blocks and/or subcarriers. The first region 905 may include a first portion of a CSI report including a rank indicator. The first region 905 may include a first number (e.g., one or more) of resource blocks and/or subcarriers.

The number of (e.g., remaining) regions may be determined based on applying a predetermined rule to the value of the rank indicator (e.g., and/or the number of remaining resource blocks and/or subcarriers other than the first number of resource blocks and/or subcarriers within the first region 905). The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node (e.g., UE) and/or the second node (e.g., BS) (e.g., based on instructions received from the second node). In some examples, the value of the rank indicator is compared to one or more thresholds. For example, a rank indicator having a first value less than or equal to (e.g., and/or greater than or equal to) a first threshold may correspond to an uplink control channel comprising two regions. Alternatively and/or additionally, a rank indicator having a second value less than or equal to (e.g., and/or greater than or equal to) a second threshold may correspond to an uplink control channel comprising three regions. Alternatively and/or additionally, a rank indicator having a third value less than or equal to (e.g., and/or greater than or equal to) a third threshold may correspond to an uplink control channel comprising four regions.

In some examples, the rank indicator may indicate a second number (e.g., number) of resource blocks and/or subcarriers corresponding to a second region 910 that includes a second portion of the CSI report. In some examples, the second portion includes PMI, CQI, and/or other content. Thus, a combination (e.g., sum, product, etc.) of the first number of resource blocks and/or subcarriers and the second number of resource blocks and/or subcarriers may correspond to a payload size of the CSI report.

In some examples, the rank indicator may indicate a third number (e.g., number) of resource blocks and/or subcarriers corresponding to (e.g., one or more) (e.g., remaining) the third region 915 that includes a third portion of the CSI report.

Fig. 10 shows a diagram 1000 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). In some examples, the CSI report may correspond to the frequency domain. Thus, the resources in the CSI report may comprise resource blocks and/or subcarriers. The uplink control channel may include a (e.g., total) number (e.g., number) of (e.g., OFDM) resource blocks and/or subcarriers (e.g., resources) corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) resource blocks and/or subcarriers. The first region 1005 may include a first portion of a CSI report including a rank indicator. The second region 1010 may include a second portion of the CSI report.

In some examples, the rank indicator may indicate (e.g., a parameter including) a code rate of the CSI report. Thus, the first node may determine the code rate based on the rank indicator. The code rate may correspond to (e.g., be used to generate and/or process) a second portion corresponding to the second region 1010.

In some examples, the rank indicator may indicate (e.g., parameters including) a modulation scheme (e.g., QPSK, BPSK, M-QAM, etc.) of the CSI report. Thus, the first node may determine the modulation scheme based on the rank indicator. The modulation scheme may correspond to (e.g., be used to generate and/or process) a second portion corresponding to the second region 1010.

The modulation scheme may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, the rank indicator having the first value may correspond to a first modulation scheme (e.g., QPSK, BPSK, M-QAM, etc.). Alternatively and/or additionally, the rank indicator having the second value may correspond to the second modulation scheme. Alternatively and/or additionally, the rank indicator having the third value may correspond to a third modulation scheme.

Fig. 11 shows a diagram 1100 of an example of CSI reporting. In some examples, the CSI reports may be mapped to uplink control channels (e.g., physical resources in the uplink control channels). A first portion of the CSI report corresponding to the first region 1105 may include a rank indicator.

The number of symbols corresponding to the second portion (e.g., and/or corresponding to the second slot) may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node. In some examples, the value of the rank indicator is compared to one or more thresholds. For example, a rank indicator having a first value less than or equal to (e.g., and/or greater than or equal to) a first threshold may correspond to a first number of symbols. Alternatively and/or additionally, a rank indicator having a second value less than or equal to (e.g., and/or greater than or equal to) a second threshold may correspond to a second number of symbols.

The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node. In some examples, the value of the rank indicator is compared to one or more thresholds. For example, a rank indicator having a first value that is less than or equal to (e.g., and/or greater than or equal to) a first threshold may correspond to a first number of resource blocks and/or subcarriers. Alternatively and/or additionally, a rank indicator having a second value less than or equal to (e.g., and/or greater than or equal to) a second threshold may correspond to a second number of resource blocks and/or subcarriers. Alternatively and/or additionally, a rank indicator having a third value less than or equal to (e.g., and/or greater than or equal to) a third threshold may correspond to a third number of resource blocks and/or subcarriers.

A code rate corresponding to the second portion (e.g., and/or corresponding to the second slot) may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node. In some examples, the value of the rank indicator is compared to one or more thresholds.

Alternatively and/or additionally, a rank indicator having a second value less than or equal to (e.g., and/or greater than or equal to) a second threshold may correspond to a second code rate. Alternatively and/or additionally, a rank indicator having a third value less than or equal to (e.g., and/or greater than or equal to) a third threshold may correspond to a third code rate.

A modulation scheme corresponding to the second portion (e.g., and/or corresponding to the second slot) may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node.

In some examples, the rank indicator may indicate a format of a second portion corresponding to the second region 1210. The format may be determined based on the rank indicator. The format may be determined based on applying a predetermined rule to the value of the rank indicator. The predetermined rules may be fixed (e.g., defined). Alternatively and/or additionally, the predetermined rule may be configured (e.g., modified) by the first node and/or the second node (e.g., based on instructions received from the second node). In some examples, a first value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) may correspond to a second portion of the CSI report corresponding to a second region 1210 that uses a long-duration format.

Alternatively and/or additionally, as shown in diagram 1300 of fig. 13, a second value of the rank indicator (e.g., greater than or equal to a threshold value and/or less than or equal to a threshold value) corresponding to the first region 1305 shown in fig. 13 may correspond to a second portion of the CSI report corresponding to a second region 1310 that uses a short duration format.

The uplink control channel may include a (e.g., total) number (e.g., number) of resources corresponding to the CSI report. The uplink control channel may be divided into regions that include adjacent (e.g., subsequent and/or adjacent to each other) symbols.
