A communication link between wireless nodes, such as between a user equipment (UE) and a base station (BS) , may be facilitated using channel state information (CSI) . 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 one or more CSIs to the BS (and/or one or more other BSs) . One signal requesting CSI from the BS may be associated with one type, while another signal requesting CSI from the BS may be associated with another type. To maintain one or more communication links, the UE may need to calculate and/or generate CSI in accordance with the type associated with the corresponding signal. However, the UE may have limited resources and/or limited capabilities.

Subject matter will now 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 as an extensive or detailed discussion of known concepts. Details that are known generally to those of ordinary skill in the relevant art may have been omitted, or may be handled in summary fashion.
The following subject matter may be embodied in a variety of different forms, such as methods, devices, components, and/or systems. Accordingly, this subject matter is not intended to be construed as limited to any example embodiments set forth herein. Rather, example embodiments are provided merely to be illustrative. Such embodiments may, for example, take the form of hardware, software, firmware or any combination thereof.
One or more computing devices and/or techniques for facilitating transmission of a channel state information (CSI) report are provided. For example, a user equipment (UE) may connect to a (e.g., wireless communication) network via a base station (BS) of the network. The BS may request one or more CSI reports from the UE. The one or more CSI reports may be used, for example, to enable the BS to communicate with the UE reliably and/or with high data rates (e.g., by enhancing signals sent from the BS to the UE based upon information in the CSI reports, etc. ) . A connection between the UE and BS may involve the transmittal of a (e.g., large) number of requests from the BS to the UE and/or a large (e.g., large) number of CSI reports from the UE to the BS. Some methods of facilitating transmission of CSI reports with low overhead which may result in the transmission of time-invalid data and/or inaccuracy (e.g., and thus provide for communication between the BS and the UE that is less reliable and/or associate with a lower data rate than is possible) . Thus, in accordance with one or more of the techniques presented herein, the transmission of CSI reports may be facilitated in a manner that balances the risk of using an excessive amount of overhead (e.g., relative to resources available) with the desire to have time-valid and/or accurate CSI reports in order to provide for optimal communication between the BS (e.g., and/or one or more other BSs) and the UE (e.g., and/or one or more other UEs) .
An example method 100A of facilitating the transmission of a CSI report 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 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, based upon the one or more reference signals, to the second node in order to maintain a connection (e.g., between the first node and the second node) . The first node may (e.g., be required to) determine and/or generate CSI content for a CSI report, such as a rank indicator, a precoding matrix indicator (PMI) , a channel quality indicator (CQI) and/or other content. Accordingly, at 105A, the first node determines a rank indicator. The rank indicator may be indicative of one or more parameters of the CSI report.
At 110A, the first node may then determine a parameter for the CSI report based upon the rank indicator. For example, the rank indicator may be indicative of a (e.g., parameter comprising a) number (e.g., quantity) of resources corresponding to the CSI report. The resources may be assigned (e.g., allocated) by the first node and/or the second node for use in generation of the CSI report. Accordingly, the first node may determine the (e.g., total) number of resources for use in generation of the CSI report based upon 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 be indicative of a (e.g., parameter comprising a) first number (e.g., quantity) of resources corresponding to a first portion of the CSI report. The (e.g., one or more) resources corresponding to the first portion may be assigned by the first node and/or the second node for use in generating the first portion. Accordingly, the first node may determine the first number of resources based upon the rank indicator. In some examples, the first portion comprises the rank indicator.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) second number (e.g., quantity) of resources corresponding to a second portion of the CSI report. The (e.g., one or more)
resources corresponding to the second portion may be assigned by the first node and/or the second node for use in generating the second portion. Accordingly, the first node may determine the second number of resources based upon the rank indicator. In some examples, the second portion comprises the PMI, the CQI and/or other content. Accordingly, a combination (e.g., sum, product, etc. ) of the first number of resources and the second number of resources may correspond to a payload size of the CSI report.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) third number (e.g., quantity) of resources corresponding to a third portion of the CSI report. The (e.g., one or more) resources corresponding to the third portion may be assigned by the first node and/or the second node for use in generating the third portion. Accordingly, the first node may determine the third number of resources based upon the rank indicator. The resources assigned to the third portion may be outside of (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 be indicative of at least one of the first number of resources, the second number of resources, the third number of resources, the number of resources to be used in generation of the CSI report and/or a combination of the first number of resources, the second number of resources, the third number of resources and/or the number of resources to be used in generation of the CSI report.
For example, the rank indicator may be indicative of 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 be indicative of the number of resources to be used in generation of the CSI report. Accordingly, the first node may determine the third number of resources (e.g., in order to generate the third portion) by determining a difference between the (e.g., total) number of resources to be used in generation of the CSI report and the combination of the first number of resources and the second number of resources.
In another example, the rank indicator may be indicative of 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 be indicative of the second number of resources. Accordingly, the first node may determine the third number of resources (e.g., in order to generate the third portion) by determining a difference between the second number of resources and the combination of the second number of resources and the third number of resources.
In another example, the rank indicator may be indicative of 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 be indicative of the third number of resources. Accordingly, the first node may determine the second number of resources (e.g., in order to generate the second portion) by determining a difference between the third number of resources and the combination of the second number of resources and the third number of resources.
In another example, the rank indicator may be indicative of the (e.g., total) number of resources to be used in generation of the CSI report. Alternatively and/or additionally, the rank indicator may be indicative of the first number of resources. Accordingly, 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., in order to generate the second portion and/or the third portion) by determining a difference between the number of resources to be used in generation of 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 comprise symbols. The symbols may comprise 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 comprise resource blocks and/or sub-carriers.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) number of repetitions of information for the CSI report. Accordingly, the first node may determine the number of repetitions of information based upon the rank indicator. The number of repetitions of information may correspond to a number of times information is to be repeated within (e.g., one or more portions of) the CSI report. For example, the number of repetitions of information may correspond to a number of times that 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 information based upon an application of predefined rules to a value of the rank indicator. The predefined rules may be fixed (e.g., defined) . Alternatively and/or additionally, the predefined rules may be configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from the second node) . In some examples, a first value of the rank indicator may correspond to one transmission of information of a portion of the CSI report (e.g., the second portion) and/or zero repetitions of information of the portion. Alternatively and/or additionally, a second value of the rank indicator may correspond to two transmissions of information of the portion and/or one repetition of information of the portion. Alternatively and/or additionally, a third value may correspond to three transmissions of information of the portion and/or two repetitions of information of the portion.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) code rate for the CSI report. Accordingly, the first node may determine the code rate based upon the rank indicator. In some examples, the CSI report does not comprise the third portion. The code rate may correspond to (e.g., be used to process) the second portion (e.g., of the CSI report) .
The first node may determine the code rate based upon an application of predefined rules to a value of the rank indicator. The predefined rules may be fixed (e.g., defined) . Alternatively and/or additionally, the predefined rules may be configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from the second node) . In some examples, a first value may correspond to a first code rate. Alternatively and/or additionally, a second value may correspond to a second code rate. Alternatively and/or additionally, a third value may correspond to a third code rate.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) modulation scheme (e.g., quadrature phase shift keying (QPSK) , binary phase shift keying (BPSK) , M-ary quadrature amplitude modulation (M-QAM) , etc. ) for the CSI report. Accordingly, the first node may determine the modulation scheme based upon the rank indicator. In some examples, the CSI report does not comprise the third portion. The modulation scheme may correspond to (e.g., be used to process) the second portion (e.g., of the CSI report) .
The first node may determine the modulation scheme based upon an application of predefined rules to a value of the rank indicator. The predefined rules may be fixed (e.g., defined) . Alternatively and/or additionally, the predefined rules may be configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from the second node) . In some examples, a first value may correspond to a first modulation scheme (e.g., QPSK, BPSK, M-QAM, etc. ) . Alternatively and/or additionally, a second value may correspond to a second modulation scheme. Alternatively and/or additionally, a third value may correspond to a third modulation scheme.
At 115A, the first node may generate the CSI report based upon the parameter and/or the rank indicator. For example, the first node may generate the first portion (e.g., of the CSI report) comprising the rank indicator. Accordingly, the first node may map the first portion (e.g., comprising the rank indicator) to the resources assigned to the first portion. Alternatively and/or additionally, the first node may generate the first portion comprising the rank
indicator and/or a relative power indicator (RPI) . For example, the rank indicator and/or the RPI may be jointly encoded. Accordingly, the first portion (e.g., comprising the rank indicator and/or the RPI) is mapped to the resources assigned to the first portion. In some examples, the RPI may be indicative of at least one of the (e.g., total) number of resources, the first number of resources, the second number of resources and/or the 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 part of) the PMI (e.g., other than the RPI) to the 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 upon the second number of resources (e.g., corresponding to the second portion) . The first node may map (e.g., at least some of) the CSI content (e.g., PMI, CQI, etc. ) to the resources assigned to the second portion (e.g., based upon the second number of resources) . Alternatively and/or additionally, the first node may generate a first sub-portion, comprising a RPI, in the second portion. Accordingly, the first sub-portion (e.g., comprising the RPI) of the second portion may be mapped to the resources assigned to the first sub-portion of the second portion. In some examples, the RPI may be indicative of at least one of the parameters including the number of resources of a second sub-portion of the second portion, code rate of the second sub-portion of the second portion, and/or modulation scheme of the second sub-portion of the second portion. In some examples, the first node may map (e.g., at least a part of) the PMI (e.g., other than the RPI) to the resources corresponding to the second sub-portion of the second portion.
In some examples, the first node may generate the third portion based upon the number of repetitions. For example, the first node may generate the third portion comprising one or more repetitions of information of the second portion. Accordingly, the first node may map repetitions of (e.g., at least some of) the CSI content (e.g., PMI, CQI, etc. ) to the resources assigned to the third portion (e.g., based upon the number of repetitions) .
In some examples, the first node may generate the second portion based upon the code rate (e.g., corresponding to the second portion) (e.g., indicated by the rank indicator) . Alternatively and/or additionally, the first node may generate the second portion based upon the 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 a first code rate and/or using a QPSK modulation scheme. Alternatively and/or additionally, the first node may generate the second portion using a second code rate and/or using a BPSK modulation scheme.
In some examples, the CSI report may correspond to the time domain. Accordingly, the resources in the CSI report may correspond to symbols. In some examples, the first node may map the first portion to a fixed (e.g., defined) location of symbols configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from 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. ) part of a slot. Alternatively and/or additionally, the first node may map the first portion to one or more symbols adjacent to (e.g., following and/or next to) one or more symbols assigned to (e.g., and/or comprising) a reference signal (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 before (e.g., and/or in front of, preceding, etc. ) one or more symbols of the third portion. Alternatively and/or additionally, the first node may map the second portion to the one or more symbols after (e.g., and/or following) the one or more symbols of the third portion.
In some examples, the CSI report may correspond to the frequency domain. Accordingly, the resources in the CSI report may comprise resource blocks and/or sub-carriers. In some examples, the first node may map the first portion to a fixed location of resource blocks (e.g., and/or sub-carriers) configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from the second node) . For example, the first node may map the first portion to one or more resource blocks and/or sub-carriers having a lowest frequency of the resource blocks and/or sub-
carriers of the resources assigned (e.g., allocated) for use in generation of the CSI report. Resource blocks and/or sub-carriers may be determined to have a lowest frequency based upon having a frequency below a frequency threshold and/or having a frequency that, when ranked against the frequencies of the resource blocks and/or sub-carriers, is below a rank threshold.
Alternatively and/or additionally, the first node may map the first portion to one or more resource blocks and/or sub-carriers having a highest frequency of the resource blocks and/or sub-carriers of the resources assigned (e.g., allocated) for use in generation of the CSI report. Resource blocks and/or sub-carriers may be determined to have a highest frequency based upon having a frequency above a frequency threshold and/or having a frequency that, when ranked against the frequencies of the resource blocks and/or sub-carriers, is above a rank threshold.
Alternatively and/or additionally, the first node may map the first portion to one or more resource blocks and/or sub-carriers having a frequency 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 sub-carriers adjacent to (e.g., following and/or next to) one or more resource blocks (e.g., and/or sub-carriers) assigned to (e.g., and/or comprising) a reference signal.
In some examples, the first node may map the second portion to one or more resource blocks and/or sub-carriers having a lower frequency than a frequency of one or more resource blocks (e.g., and/or sub-carriers) of the third portion. Alternatively and/or additionally, the first node may map the second portion to the one or more resource blocks (e.g., and/or sub-carriers) having a higher frequency than the frequency of the one or more symbols of the third portion.
At 120A, the first node transmits the CSI report to the second node. In some examples, the first node transmits one or more CSI reports to the second node in one or more slots (e.g., and/or time-slots) . In some examples, there may be a time gap (e.g., of 5 ms) between a first slot and a second (e.g.,
next) slot. In some examples, the first node transmits the CSI report in a (e.g., single) slot.
In some examples, the first node is configured to transmit one or more CSI reports in a multiple transceiver point (TRP) transmission configuration (e.g., in one or more slots) . For example, a first plurality of resources may be assigned to (e.g., and/or comprise) a first portion of a first CSI report and/or a first portion of a second CSI report. In some examples, a second plurality of resources may be assigned to (e.g., and/or comprise) a second portion of the first CSI report and/or a second portion of the second CSI report. In some examples, a third plurality of resources may be assigned to (e.g., and/or comprise) 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 comprises a rank indicator, indicative of one or more parameters of the second portion of the first CSI report and/or the second portion of the first CSI report. In some examples, the first portion of the second CSI report comprises a rank indicator, indicative of one or more parameters of the second portion of the second CSI report and/or the third portion of the second CSI report. In some examples, the first portion of the first CSI report and/or 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 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 or the third portion of the second CSI report are jointly encoded within the third plurality of resources. In some examples, the first node may transmit the first plurality of resources, in a first slot, and the second plurality of resources, in a second slot, to a primary TRP or to a plurality of TRPs.
An example method 100B of facilitating the transmission of a CSI report from a first node to a second node is illustrated in Fig. 1 B. The first node may be a UE and the second node may be a network and/or 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, based upon the one or more reference signals, to the second node in order to
maintain a connection (e.g., between the first node and the second node) . Accordingly, at 105B, the first node may receive a (e.g., reference) signal from the second node. In some examples, the signal may comprise (e.g., an indication of) a number of repetitions of information (e.g., configured by the second node) .
The first node may (e.g., be required to) determine and/or generate CSI content for a CSI report, such as a rank indicator, a PMI, a CQI and/or other content, based upon the signal. Accordingly, at 110B, the first node may determine the number of repetitions of information for the CSI report based upon the signal. Alternatively and/or additionally, the first node may determine a rank indicator, indicative of one or more parameters of the CSI report.
In some examples, the number of repetitions of information may correspond to a number of times information is to be repeated within (e.g., one or more portions of) the CSI report. For example, the number of repetitions of information may correspond to a number of times that the 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.
Accordingly, at 115B, the first node may generate the CSI report based upon the number of repetitions of information. In some examples, the first node may generate the first portion based upon the number of repetitions. For example, the first node may generate the first portion comprising one or more repetitions of the rank indicator. Accordingly, the first node may map the first portion (e.g., comprising 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 upon (e.g., at least some of) CSI content for the CSI report, such as the PMI, the CQI and/or other content. The first node may map the CSI content to resources assigned to the second portion. Accordingly, at 120B, the first node may transmit the CSI report to the second node. In some examples, the first node transmits the CSI report in a (e.g., single) slot.
Alternatively and/or additionally, the first node may generate the first portion comprising the rank indicator and/or a RPI. For example, the rank indicator and/or the RPI may be jointly encoded. Accordingly, the first portion (e.g., comprising the rank indicator and/or the RPI) is mapped to the resources assigned to the first portion. In some examples, the RPI may be indicative of at least one of the (e.g., total) number of resources, the first number of resources, the second number of resources and/or the 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 part of) the PMI (e.g., other than the RPI) to the resources corresponding to the second portion.
An example method 100C of facilitating the transmission of a CSI report from a first node to a second node is illustrated in Fig. 1C. The first node may be a UE and the second node may be a network and/or 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, based upon the one or more reference signals, to the second node in order to maintain a connection (e.g., between the first node and the second node) . The first node may (e.g., be required to) determine and/or generate CSI content for a CSI report, such as a rank indicator, a PMI, a CQI and/or other content. Accordingly, at 105C, the first node determines a rank indicator. The rank indicator may be indicative of one or more parameters of the CSI report.
At 110C, the first node may then determine a parameter for the CSI report based upon the rank indicator. For example, the first node may determine a (e.g., total) number of resources for use in generation of the CSI report based upon the rank indicator. Alternatively and/or additionally, the first node may determine a first number (e.g., quantity) of resources corresponding to a first portion of the CSI report based upon the rank indicator. In some examples, the first portion comprises the rank indicator. Alternatively and/or additionally, the first node may determine a second number (e.g., quantity) of resources corresponding to a second portion of the CSI report based upon the rank indicator. In some examples, the second portion comprises the PMI, the
CQI and/or other content. Alternatively and/or additionally, the first node may determine a third number (e.g., quantity) of resources corresponding to a third portion of the CSI report.
In some examples, the CSI report may correspond to the time domain. Accordingly, 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 comprise 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 comprise resource blocks and/or sub-carriers.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) number of repetitions of information for the CSI report. Accordingly, the first node may determine the number of repetitions of information based upon the rank indicator. In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) code rate for the CSI report. Accordingly, the first node may determine the code rate based upon the rank indicator. In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) modulation scheme for the CSI report. Accordingly, the first node may determine the modulation scheme based upon the rank indicator.
In some examples, the rank indicator may be indicative of a (e.g., parameter comprising a) format for the second portion of the CSI report (e.g., and/or the third portion of the CSI report) . Accordingly, the first node may determine the format based upon the rank indicator. The first node may determine the format based upon an application of predefined rules to a value of the rank indicator. The predefined rules may be fixed (e.g., defined) . Alternatively and/or additionally, the predefined rules may be configured (e.g., modified) by the first node and/or the second node (e.g., based upon instructions received from the second node) . In some examples, a first value
