Patent Description:
These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform-spread-OFDM (DFT-S-OFDM). A wireless multiple-access communications system may include a number of base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as a UE.

In some wireless communications systems, a UE may be configured to transmit CSI reports. In some cases, CSI reports may collide and try to use the same communication resources, which can lead to problems.

Document <NPL> discloses that for CSI reporting, the priority rule bases on time-domain behavior/channel, CSI content, cellID and csiReportID information.

Patent application publication <CIT> discloses a method for operating a terminal for feedback on channel state information (CSI) in a carrier aggregation system, comprising the steps of receiving CSI feedback configuration information for each of a plurality of downlink component carriers from a base station; and feeding channel status information back to the base station through a physical uplink control channel (PUCCH) of an uplink primary component carrier on the basis of the configuration information of the received CSI feedback. Document "<NPL>" and document "<NPL>" are the documents in the technical field in question.

Patent application publication <CIT> discloses a UE that may transmit an indication of the first CSI and may drop the second CSI based at least in part on prioritizing the first CSI over the second CSI.

Aspects of the invention are defined in the claims The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for prioritizing channel state information (CSI) reporting. Generally, the described techniques provide for determining a priority ranking for CSI reports based on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra-reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters, or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters, latency parameters, or both based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based on a slot set identifier.

In some wireless communications systems, a user equipment (UE) may be configured to communicate using both enhanced mobile broadband (eMBB) services and ultra reliable low latency communication (URLLC) services. In such systems, channel state information (CSI) reports for both types of services may be multiplexed.

Techniques are described herein for determining a priority ranking for CSI reports based at least in part on a reliability parameter, a latency parameter, or both associated with a UE. In some wireless communications systems, URLLC services may be interspersed or multiplexed with eMBB services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters, or both. In some cases, CSI reporting for resources associated URLLC services may receive a different priority (e.g., a higher priority) than resources allocated for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from another device or devices, such as the network, or from determining the parameters based on one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based on a slot set identifier.

Aspects of the disclosure are initially described in the context of a wireless communications systems. Aspects of the disclosure are described in the context of a process flow related to CSI reporting. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for prioritizing CSI reports.

<FIG> illustrates an example of a wireless communications system <NUM> that supports techniques for prioritizing CSI reports in accordance with aspects of the present disclosure. The wireless communications system <NUM> includes base stations <NUM>, UEs <NUM>, and a core network <NUM>. In some examples, the wireless communications system <NUM> may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some cases, wireless communications system <NUM> may support enhanced broadband communications, ultra reliable (e.g., mission critical) communications, low latency communications, or communications with low-cost and low-complexity devices.

In some cases, UEs <NUM> may be designed to support critical functions (e.g., mission critical functions), and a wireless communications system <NUM> may be configured to provide ultra reliable communications for these functions.

In one example, a base station <NUM> may use multiple antennas or antenna arrays to conduct beamforming operations for directional communications with a UE <NUM>. For instance, some signals (e.g. synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station <NUM> multiple times in different directions, which may include a signal being transmitted according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by the base station <NUM> or a receiving device, such as a UE <NUM>) a beam direction for subsequent transmission and/or reception by the base station <NUM>. Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station <NUM> in a single beam direction (e.g., a direction associated with the receiving device, such as a UE <NUM>). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based at least in in part on a signal that was transmitted in different beam directions. For example, a UE <NUM> may receive one or more of the signals transmitted by the base station <NUM> in different directions, and the UE <NUM> may report to the base station <NUM> an indication of the signal it received with a highest signal quality, or an otherwise acceptable signal quality. Although these techniques are described with reference to signals transmitted in one or more directions by a base station <NUM>, a UE <NUM> may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE <NUM>), or transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

The single receive beam may be aligned in a beam direction determined based on listening according to different receive beam directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio, or otherwise acceptable signal quality based on listening according to multiple beam directions).

For example, the carrier bandwidth may be one of a number of predetermined bandwidths for carriers of a radio access technology (e.g., <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, or <NUM>).

Devices of the wireless communications system <NUM> (e.g., base stations <NUM> or UEs <NUM>) may have a hardware configuration that supports communications over a particular carrier bandwidth, or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system <NUM> may include base stations <NUM> and/or UEs <NUM> that can support simultaneous communications via carriers associated with more than one different carrier bandwidth.

Wireless communications systems such as an NR system may utilize any combination of licensed, shared, and unlicensed spectrum bands, among others. The flexibility of eCC symbol duration and subcarrier spacing may allow for the use of eCC across multiple spectrums. In some examples, NR shared spectrum may increase spectrum utilization and spectral efficiency, specifically through dynamic vertical (e.g., across the frequency domain) and horizontal (e.g., across the time domain) sharing of resources.

The UE <NUM> may be configured to determine a priority ranking for a CSI report based on a reliability parameter and/or a latency parameter associated with the UE <NUM>. In such cases, CSI reports associated with first reliability parameters (e.g., higher reliability parameters) and/or first latency parameters (e.g., higher reliability parameters) may be given higher priority than CSI reports associated with second reliability parameters (e.g., lower reliability parameters) and/or second latency parameters (e.g., lower reliability parameters). For example, CSI reports associated with a URLLC service may be given higher priority than CSI reports associated with an eMBB service.

<FIG> illustrates an example of a wireless communications system <NUM> that supports techniques for prioritizing CSI reports in accordance with aspects of the present disclosure. In some examples, the wireless communications system <NUM> may implement aspects of the wireless communications system <NUM>. The wireless communications system <NUM> may include one or more base stations <NUM> and one or more UEs <NUM>. The base stations <NUM> may be examples of the base stations <NUM> described with reference to <FIG>. The UEs <NUM> may be examples of the UEs <NUM> described with reference to <FIG>.

In the wireless communications system <NUM>, channel conditions experienced by a UE <NUM> may change. For example, as a UE <NUM> moves through a coverage area (e.g., down a street), the UE <NUM> may experience varying radio conditions (e.g., fading). To account for these changing channel conditions, the UE <NUM> may be configured to report information about channel conditions to the base station <NUM>. The base station <NUM> may use this information to allocate resources of the wireless communications system <NUM> to the UE <NUM> and/or other components.

The information sent by the UE <NUM> may be in the form of a CSI report <NUM>. CSI information may act as an indicator about how good or bad channel conditions on a specific channel are at a specific time. CSI may include a channel quality indicator (CQI), a precoding matrix index (PMI), and a rank indicator (RI). To generate a CSI report, the UE <NUM> may receive and analyze one or more CSI reference signals (CSI-RSs) and/or other reference signals and determine feedback information (e.g., CQI, PMI, or RI) based on those reference signals.

A UE <NUM> may be configured to transmit CSI reports <NUM> on a periodic basis, a semi-persistent basis, or an aperiodic basis. For example, for periodic transmissions, an RRC message may configure a time interval between the transmission of CSI reports <NUM>. For aperiodic transmissions, the base station <NUM> may request that the UE <NUM> transmit the CSI report <NUM>. In some cases, CSI reports <NUM> may be used for portions of a wireless spectrum. For example, a CSI report <NUM> may be used for a portion of the frequency band spectrum allocated to the UE <NUM>. In other examples, a CSI report <NUM> may be for a sub-band or some or portion of the spectrum allocated to the UE <NUM>.

In some cases, the UE <NUM> may be requested to provide a plurality of CSI reports to the base station <NUM> and/or the network more generally. In such cases, the UE <NUM> may be configured to multiplex the CSI reports. In some cases, the UE <NUM> may generate a priority ranking of the CSI reports <NUM> to facilitate multiplexing the CSI reports and determining which CSI reports are more likely to be transmitted using limited resources. For example, two CSI reports may collide if the time occupancy of the physical channels scheduled to carry the CSI reports overlap in at least on OFDM symbol and are transmitted on the carrier. When the UE <NUM> attempts to transmit colliding CSI reports, the UE <NUM> may use priority rankings to resolve the collision to enable more effective and/or efficient communications.

In some wireless communications systems, CSI reports <NUM> may be ranked or prioritized based on the CSI type, the CSI content, the CC index, or the CSI report identifier, or a combination thereof. Examples of the CSI type may include aperiodic CSI (A-CSI), semi-persistent CSI (SP-CSI) on a physical uplink shared channel (PUSCH), SP-CS on a physical uplink control channel (PUCCH), or periodic CSI (P-CSI). Examples of CSI content may include narrowband CQI, wideband CQI, PMI, RI, received signal received power (RSRP), received signal received quality (RSRQ), or received signal strength indicator (RSSI).

Techniques are described herein for determining a priority ranking for CSI reports based on a reliability parameter, a latency parameter, or both of resources allocated to the UE <NUM>. In some wireless communications systems, URLLC services may be interspersed with eMBB services. CSI report prioritization procedures may be configured to account for reliability parameters, latency parameters, or both. In some cases, CSI reporting for resources allocated to URLLC services may receive higher priority than CSI reporting for eMBB services. The UE <NUM> may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE <NUM>. In some cases, the priority ranking of the CSI report may be based on a slot set identifier.

<FIG> illustrates an example of a process flow <NUM> that supports techniques for prioritizing CSI reports in accordance with aspects of the present disclosure. In some examples, the process flow <NUM> may implement aspects of the wireless communications systems <NUM> and <NUM>. The process flow <NUM> may include functions performed and communications exchanged between a base station <NUM> and a UE <NUM>. The base station <NUM> may be an example of the base stations <NUM> and <NUM> described with reference to <FIG> and <FIG>. The UE <NUM> may be an example of the UEs <NUM> and <NUM> described with reference to <FIG> and <FIG>.

The process flow <NUM> may illustrate techniques for determining a priority ranking of a CSI report based on at least one of a reliability parameter or a latency parameter associated with the CSI report. For example, CSI reports that are associated with URLLC services may be given a higher priority ranking than CSI reports associated with eMBB services, among other examples.

The base station <NUM> may optionally transmit a message <NUM> to the UE <NUM>. The message <NUM> may include information related to determine a priority ranking for a CSI report <NUM>. In some cases, the message <NUM> may be an example of downlink control information or a radio resource control (RRC) message. In some examples, the message <NUM> may be a grant of resources and may indicate a service type of the resources, a quality of service (QoS) parameter associated with the resources, or other configurations of the UE <NUM>. In some cases, the message <NUM> may include a request for a CSI report (e.g., an aperiodic CSI report). In some cases, the message <NUM> may include information that causes the UE <NUM> to configure CSI reports (e.g., periodic CSI reports).

At block <NUM>, the UE <NUM> may determine a reliability parameter, a latency parameter, or both associated with a CSI report <NUM>. To determine these parameters, the UE <NUM> may use explicit signaling at block <NUM> and/or may use implicit determinations at block <NUM>.

At block <NUM>, the UE <NUM> may determine the reliability parameter and/or the latency parameter associated with the CSI report <NUM> based on information included in the message <NUM>. In some cases, the UE <NUM> may receive downlink control information that indicates the reliability parameter, the latency parameter, or both. In such cases, the message <NUM> may be an example of the downlink control information. The downlink control information may include one or more bits that indicate a trigger for an aperiodic CSI report. In some cases, the downlink control information may indicate that the aperiodic CSI report is associated with a URLLC service. In some cases, the field of the downlink control information configured to trigger an A-CSI report or CSI report more generally may include one or more additional bits to indicate a redundancy parameter and/or a latency parameter associated with the CSI report. In some cases, the downlink control information may include a new field of one or more bits to indicate a redundancy parameter and/or a latency parameter associated with a CSI report.

In some cases, the UE <NUM> may receive an RRC message that indicates the reliability parameter, the latency parameter, or both. In such cases, the message <NUM> may be an example of the RRC message. The RRC message may be used to configure periodic CSI reports and/or semi-persistent CSI reports. In some cases, the RRC message may indicate that the periodic CSI reports and/or the semi-persistent CSI reports are associated with a URLLC service. The RRC message may configure periodic CSI reports and/or semi-persistent CSI reports associated with a URLLC service on certain component carriers, certain slots, certain symbols, or a combination thereof.

In some cases, the UE <NUM> may receive a grant of resources from the base station <NUM> that indicates the reliability parameter, the latency parameter, or both. In such cases, the message <NUM> may be an example of the grant of resources. The grant of resources may include a QoS parameter associated with the CSI report or associated with the granted resources. The UE <NUM> may determine the QoS parameter based on receiving the message <NUM>. The UE <NUM> may determine the reliability parameter, the latency parameter, or both based on the QoS parameter.

In some cases, the UE <NUM> may determine a service type of resources allocated to the UE <NUM> by the base station <NUM>. A service type may include eMBB, URLLC, and/or mMTC. The UE <NUM> may determine that resources associated with the CSI report <NUM> are allocated for an eMBB service or a URLLC service. The UE <NUM> may determine the reliability parameter and/or the latency parameter associated with the CSI report <NUM> based on determining the service type.

At block <NUM>, the UE <NUM> may determine the reliability parameter and/or the latency parameter based on determinations made by the UE <NUM>. In some cases, the UE <NUM> may determine that one or more configurations of the UE <NUM> have been modified. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on the modifications in these configurations. For example, a new block error rate (BLER) table may indicate the reliability parameter and/or the latency parameter.

In some cases, the UE <NUM> may determine that a new modulation and coding scheme (MCS) table different than an initial MCS table is configured for the UE <NUM>. The new MCS table may be associated with URLLC services or reliable communications or low-latency communications. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on the new MCS table being configured or based on the content of the new MCS table or both.

In some cases, the UE <NUM> may adjust the initial MCS. The adjusted MCS table may be associated with URLLC services or reliable communications or low-latency communications. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on the adjusted MCS table being configured or based on the content of the adjusted MCS table, or both.

In some cases, the UE <NUM> may identify that a new radio network temporary identifier (RNTI) different than an initial RNTI is configured for the UE <NUM>. In some cases, the UE <NUM> may identify that the initial RNTI is adjusted. The new RNTI or the adjusted RNTI may be associated with URLLC services or reliable communications or low-latency communications. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on the new RNTI or the adjusted RNTI being configured, the content of the new RNTI or the adjusted RNTI, or both. The UE <NUM> may determine whether downlink control information is scrambled using the new RNTI, the adjusted RNTI, or the initial RNTI. In some cases, cyclic redundancy check (CRC) bits of the downlink control information are scrambled using the new RNTI, the adjusted RNTI, or the initial RNTI. In such cases, the UE <NUM> may generate CRC bits based on information bits of the downlink control information, scramble the CRC bits with some RNTI, concatenate the scrambled CRC bits and the information bits of the downlink control information, and encode the string of concatenated bits. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on determining that the at least a portion of the downlink control information (e.g., CRC) is scrambled using the new RNTI, the adjusted RNTI, or both. In some cases, the UE <NUM> may determine that a CSI report associated with a URLLC service is to be generated and transmitted based on a new RNTI or the adjusted RNTI.

In some cases, when the new RNTI is configured (via RRC), RNTI scrambling of the CRC of the downlink control information may be used to determine reliability parameter and/or the latency parameter of the CSI report <NUM>. In some examples, A-CSI or SP-CSI with a higher reliability parameter and/or a higher reliability parameter may be triggered or activated by receiving downlink control information whose CRC is scrambled with the new RNTI. Similarly, A-CSI or SP-CSI with a lower reliability parameter and/or a lower reliability parameter may be triggered or activated by receiving downlink control information whose CRC is scrambled with the old RNTI.

In some cases, when a new RNTI or an adjusted RNTI is not configured, an RRC parameter may be used to configure a new MCS table or an adjusted MCS table. When the new MCS table is configured, the UE <NUM> may identify a search space where a downlink control information is received. For example, the downlink control information may be received in a common search space (CSS), and/or a UE-specific search space (USS). The UE <NUM> may determine the reliability parameter and/or the latency parameter associated with the CSI report <NUM> based on identifying the search space used to receive the downlink control information. In other words, the UE <NUM> may monitor two downlink control information search spaces (e.g., CSS and USS). If downlink control information (DCI) is found in CSS, the CSI reports triggered or activated by that DCI may have a lower priority (e.g., lower reliability parameter and/or higher latency parameter). If a DCI is found in USS, the CSI reports triggered or activated by that DCI may have a higher priority (e.g., a higher reliability parameter and/or a lower latency parameter). In some cases, A-CSI or SP-CSI that is triggered or activated by downlink control formats 0_0/1_0/0_1/1_1 in USS may have a higher priority than A-CSI or SP-CSI that is triggered or activated by downlink control formats 0_0/1_0 in CSS. In other cases, USS and CSS may indicate the same reliability parameters and/or latency parameters for the CSI report <NUM>.

In some cases, the UE <NUM> may determine a CSI reference signal (CSI-RS) configuration for the UE <NUM>. Some CSI-RS configuration may be associated with eMBB services while others may be associated with URLLC services. The UE <NUM> may determine the reliability parameter and/or the latency parameter based on the CSI-RS configuration. The CSI-RS configuration may include information associated with a density of CSI-RSs, a pattern of CSI-RSs, one or more ports used to communicate CSI-RSs, or a periodicity of CSI-RSs, or a combination thereof.

At block <NUM>, the UE <NUM> may determine a slot set identifier associated with the CSI report <NUM>. The slot set identifier may indicate whether the CSI report <NUM> is associated with an uplink communication or a downlink communication. The priority ranking of the CSI report <NUM> may be determined using the slot set identifier as well as reliability indicator and/or the latency parameter.

At block <NUM>, the UE <NUM> may optionally generate a combined parameter using at least the reliability parameter and the latency parameter. In some cases, the UE <NUM> may use the reliability parameter or the latency parameter (in some cases, only the reliability parameter or only the latency parameter) to determine the priority ranking of the CSI report <NUM>. In other cases, the UE <NUM> may use both the reliability parameter and the latency parameter to determine the priority ranking. In yet other cases, such as at block <NUM>, the UE <NUM> may combine the reliability parameter and the latency parameter into a combined parameter and use that combined parameter to determine the priority ranking of the CSI report <NUM>.

In some cases, the combined parameter may include content of uplink control information as well as the reliability parameter and the latency parameter associated with the CSI report <NUM>. The content of uplink control information may include a scheduling request, a HARQ acknowledgement (ACK) or HARQ negative acknowledgment (NACK), or CQI. At least a portion of the content of the uplink control information (UCI) may be included in the combined parameter. In some cases, the combined parameter may include the slot set identifier.

At block <NUM>, the UE <NUM> may weight one or more parameters to generate the priority ranking. Weighting may include applying a factor to the parameter. In some cases, the parameter may be multiplied by the factor. In some cases, the factor may be associated with a number of CSI reports configured for the UE <NUM>. In some cases, the factor may include a numeric multiplier, a number of component carriers of resources associated with the UE <NUM>, a second number of CSI reports associated with each component, or a combination thereof. Additional examples of the weighting are described herein.

At block <NUM>, the UE <NUM> may determine a priority ranking of the CSI report <NUM> based on one or more parameters. For example, the UE <NUM> may determine the priority ranking of the CSI report <NUM> based on the reliability parameter, the latency parameter, a CSI type, a CSI content, a component carrier (CC) index, a CSI report identifier, or a slot set identifier, or a combination thereof.

Equation <NUM> illustrates how the UE <NUM> may prioritize CSI reports for intra-UE eMBB and URLLC multiplexing. In Equation <NUM>, a CSI report associated with a URLLC service may have priority over a CSI report associated with an eMBB service, regardless of the CSI type. <MAT> In Equation <NUM>, PriiCSI may represent the priority ranking of the CSI report <NUM>. The parameters x, y, k, c, and s may represent different inputs of the priority ranking equation. The parameter s may represent the CSI report identifier (e.g., a reportConfigID), the parameter c may represent the component carrier index (e.g., a service cell index), the parameter k may represent the CSI content (e.g., k = <NUM> for CSI reports carrying L1-RSRP and k = <NUM> for CSI reports not carrying L1-RSRP), and the parameter y may represent the CSI type (e.g., A-CSI, SP-CSI on PUSCH, SP-CSI on PUCCH, or P-CSI). The parameter x may represent the service type (e.g., eMBB or URLLC), the reliability parameter, the latency parameter, or the combined parameter that includes at least the reliability parameter and the latency parameter. For example, x may equal <NUM> if a new CSI table is associated with the CSI and x may equal <NUM> otherwise. The variable Ncells may represent the number of components carriers associated with the UE. In some cases, the variable Ncells may be the value of the parameter maxNrofServingCells. The variable Ms may represent the number of CSI reports associated with each component carrier associated with the UE <NUM>. In some cases, the variable Ms may be the value of the parameter maxNrofCSI-ReportConfigurations. In some cases, Equation <NUM> may include a parameter associated with the slot set identifier. In such cases, a factor may or may not be applied to the parameter associated with the slot set identifier.

Different factors may be applied to one or more or each parameter to determine the priority ranking of the CSI report <NUM>. The factors may weight each parameter differently during the priority ranking determination. Applying different factors may cause different parameters to become more important during the determination of the priority ranking. For example, the factor <NUM> * Ncells * Ms may be applied to the parameter x and no factor may be applied to the parameter s. In such examples, the parameter x may be weighted to have a higher value and a higher influence than the parameter s. Examples of other factors in Equation <NUM> may include <NUM> * Ncells * Ms, Ncells * Ms, Ms, or a combination thereof. While an example of factors is shown in Equation <NUM>, any factor may be applied to any parameter.

Equation <NUM> illustrates a single parameter x used to denote the reliability parameter, the latency parameter, the combined parameter, or some other related parameter. In some cases, an equation for the priority ranking of CSI reports may include a parameter r for reliability and a separate parameter <NUM> for latency. These parameters may replace the parameter x in Equation <NUM> in some cases. Factors may be applied to the parameter r and/or the parameter <NUM>. In some cases, the same factor is applied to both the parameter r and the parameter <NUM>. In some cases, different factors may be applied to the parameter r and the parameter <NUM>. An example of the factors applied to the parameter r and/or the parameter <NUM> may include <NUM> * Ncells * Ms or <NUM> * <NUM> * Ncells * Ms.

Equation <NUM> and/or Table <NUM> illustrate how the UE <NUM> may jointly consider a reliability parameter, the latency parameter, and content of the uplink control information to determine the priority ranking of the CSI report <NUM>. <MAT> In Equation <NUM>, the parameter x may jointly depend on the service type (e.g., eMBB or URLLC) and the content of the uplink control information. The other variables, parameters, and factors of Equation <NUM> may be similarly embodied as the variables, parameters, and factors described with reference to Equation <NUM>. An example of values of the parameter x are shown in Table <NUM>.

Like Equation <NUM>, Equation <NUM> may include a parameter r and/or a parameter <NUM> instead of the parameter x and any factors may applied to these parameters. In some cases, Equation <NUM> may include a parameter associated with the slot set identifier. In such cases, a factor may or may not be applied to the parameter associated with the slot set identifier.

The UE <NUM> may transmit the CSI report <NUM> based on the priority ranking of the CSI report <NUM>. The UE <NUM> may transmit the CSI report <NUM> to the base station <NUM>. The base station <NUM> may use the CSI report <NUM> to determine channel conditions and to adjust communication parameters or to allocate resources to UEs.
