[0001]Priority rules for CRI based CSI reporting of multiple CSI reports with M reported beams Cross Reference to other Applications This application claims priority to Indian Provisional Patent Application No. 202441074567 entitled “Priority rules for CRI based CSI reporting of multiple CSI reports with M reported beams” filed on October. 02, 2024, Indian Provisional Patent Application No. 202441085586 entitled “Priority determination for multi beam CSI reporting” filed on November. 07, 2024, which are incorporated herein by reference for all purposes. Field of the Invention The present invention relates to wireless communication technology, specifically to methods and systems for enhancing channel state information (CSI) reporting in massive MIMO systems. More particularly, it focuses on techniques for prioritizing multiple CSI reports to efficiently manage reporting overhead. Background of the Invention The rapid growth in data demand and the rising number of users in future wireless networks require radio access technologies (RAT) that can achieve much higher spectral efficiency. Massive MIMO, where base stations (gNBs) employ hundreds or even thousands of antennas, has emerged as a key technology to meet this requirement. To support many users in the same frequency band, hybrid analog / digital beamforming has been proposed, especially in higher frequency ranges (FR2 and FR3), which provide large bandwidths but also face higher propagation losses. Hybrid beamforming offers a practical trade-off between performance, cost, and power consumption, and is also effective in lower frequencies (FR1). While 3GPP specifications do not mandate a specific beamforming design, the channel state information (CSI) framework defined in 5G NR has evolved in alignment with such architectures. In NR, user equipment (UE) measures the downlink channel using CSI reference signals (CSI-RS) transmitted by the gNB, quantizes the measurements, and reports them back as uplink control information (UCI). The gNB configures one or more CSI reporting configurations that map CSI-RS resources to channel measurement reports (CMRs). Depending on the configuration, CSI reporting can be aperiodic (AP), semi-persistent (SP), or periodic (P), transmitted over either the physical uplink shared channel (PUSCH) or the physical uplink control channel (PUCCH). Each CSI report may include indicators such as Channel Resource Indicator (CRI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), and Channel Quality Indicator (CQI), with the reports divided into Part 1 (basic CSI) and Part 2 (detailed precoding information). Up to Release 18, CSI reporting was primarily single-CRI based, where each report carried information about one beam. Priority rules for handling multiple reports and CSI omissions were therefore defined mainly in terms of report configuration IDs and serving cell IDs. However, with the introduction of Release 19 multi-CRI CSI reporting, a UE may report measurements of multiple beams (M CRIs) in a single CSI instance, significantly increasing the feedback payload size. While this enables improved beam management and channel knowledge at the gNB, it also introduces challenges, particularly when multiple CSI reports collide in the uplink. The existing priority rules, designed for single-CRI reports, do not consider the number of CRIs in a report and are therefore not sufficient for multi- CRI reporting. Inefficient handling of multi-CRI CSI reporting may lead to suboptimal beamforming, inefficient resource allocation, and degraded user experience in dense network deployments. As networks evolve to 5G-Advanced and 6G, it becomes critical to update the CSI priority rules in line with the new multi-CRI framework of Release 19 and beyond. As CSI reporting evolves to support multiple CRIs per report in Release 19, the feedback overhead becomes large, and the probability of CSI omission increases. The current priority rules for resolving collisions among multiple CSI reports do not account for the multi-CRI aspect. Hence, there is a need for enhanced CSI priority rules that integrate the number of CRIs (M) or non-reported CRIs (MR) into the decision criteria, ensuring efficient omission handling and improved network performance. Objective of the Invention The principal objective of the present invention is to optimize the assignment of priority levels to channel state information (CSI) reports by incorporating the number of CSI-RS resource indicators (CRIs) present in each report, thereby enhancing packing efficiency and improving the reliability of uplink transmissions. Another objective of the present invention is to establish a robust framework for CSI reporting that guarantees a minimum number of Channel Measurement Reports (CMRs) are reported across all CSI instances, even in the presence of CSI omissions, thereby enhancing network reliability and minimizing performance degradation in dense deployment scenarios. Another objective of the present invention is to implement a dynamic mechanism for configuring CSI reporting strategies based on real-time network conditions and user equipment (UE) capabilities, thereby accommodating both configured and non-configured multi-beam (MR) reporting scenarios in a flexible and adaptive manner. A further objective of the present invention is to integrate enhanced CSI priority rules that jointly consider both the number of reported CRIs (M) and the maximum number of non-reported CRIs (MR), enabling efficient omission handling, better utilization of feedback resources, and improved beamforming decisions. Another objective of the present invention is to ensure backward compatibility with legacy single-CRI CSI reporting rules, while extending the framework to fully support multi-CRI CSI feedback introduced in 5G NR Release 19 and beyond. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The present invention relates to methods and system for enhancing Channel State Information (CSI) reporting in 5G-Advanced (5G-A), Release 19, and beyond. In particular, the invention addresses the limitations of legacy CSI omission rules, which were designed for single-CRI reporting, and extends them to efficiently support multi-CRI CSI feedback where multiple beams are reported within a single CSI instance. According to aspects of the invention, CSI report priority determination is enhanced by incorporating multi-beam characteristics, such as the maximum number of reported CRIs (M) and the maximum number of non-reported CRIs (MR), into the priority rule. This enables more efficient omission handling when multiple CSI reports collide on the uplink, while still preserving backward compatibility with legacy single-CRI priority rules. In one embodiment, the invention provides a first method wherein the 2M consecutive priority levels of M CRIs are linked with the priority of multiple CSI reports such that reports with larger M values are prioritized. In another embodiment, a second method is proposed where MR-based priorities are applied, ensuring that a minimum subset of CRIs is reported across all CSI reports even under omission conditions. In yet another embodiment, a third method combines both M and MR, providing a flexible and adaptive approach that can be tailored by the network depending on reporting configuration and UE capability. The invention also defines enhanced priority equations that extend the legacy rules defined in 3GPP TS 38.213 and TS 38.214 by conditioning the priority function on M, MR, or both. These modifications enable efficient integration of the new multi-CRI framework into the stable CSI architecture while avoiding disruption of existing priority orders. By refining omission handling for CSI reports, the present invention improves packing efficiency, robustness, and fairness of feedback transmission in uplink channels. This ensures that critical channel measurements are not entirely lost in the event of collisions, thereby enhancing beamforming accuracy, scheduling decisions, and overall network performance. The disclosed methods are applicable across frequency ranges FR1, FR2, FR3, and THz, and are suitable for both single- panel and multi-panel codebooks, including hybrid beamforming and multi-TRP architectures.

Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces. Figure 1 illustrates the conventional priority assignment framework (100) for channel state information (CSI) omission in 5G New Radio (NR) systems as defined in 3GPP Releases 18 and early 19 agreements. In NR, the channel state information (CSI) of a downlink communication channel is evaluated by the user equipment (UE) by means of pilot signals called CSI reference signals (CSI-RS) configured by the gNB. The UE further quantizes the estimated CSI and feeds back the same to gNB via uplink control information (UCI) reporting. To accomplish an efficient closed loop feedback, gNB sends CSI reporting configuration that configures the UE with multiple CSI-RS resources for channel measurement reports (CMRs). The gNB may configure the UE with a single CSI reporting configuration or multiple CSI report configurations. 5G NR allows four main report scheduling methods (indicated by the reportConfigType), namely, aperiodic (AP) reporting with CSI on PUSCH, semipersistent (SP) with CSI on PUSCH, SP on PUCCH and periodic (P) on PUCCH. The mapping between CSI report configuration and gNB configured CSI-RS resources is illustrated in table 1. CSI-RS Periodic CSI Semi-Persistent CSI Aperiodic CSI Configuration Reporting Reporting Reporting Periodic No dynamic For reporting on PUCCH, For reporting on CSI-RS triggering / activation the UE receives an PUSCH, the UE activation command; receives triggering on for reporting on PUSCH, DCI the UE receives triggering on DCI Semi-Persistent Not Supported For reporting on PUCCH, For reporting on CSI-RS the UE receives an PUSCH, the UE activation command; receives triggering on for reporting on PUSCH, DCI the UE receives triggering on DCI Aperiodic Not Supported Not Supported For reporting on CSI-RS PUSCH, the UE receives triggering on DCI Table 1: Priority reporting levels in 5G NR for configure n CSI reports aiding Part 2 CSI omission In some aspects, traditional SP (Semi-Persistent) and P (Periodic) CSI reports on control channel (PUCCH) are triggered through higher layer RRC signalling or low layer MAC CE triggering. The SP and AP CSI reporting over data channel (PUSCH) are triggered via low layer DL control information (DCI) triggering. Based on the report configuration and trigger, the UE appropriately reports the CSI feedback information corresponding to the selected CSI-RS resource. The CSI-ReportConfig also specifies other aspects like codebookConfig indicating the codebook type and reportQuantity indicating the type of measurement being made. A UE may be configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to either 'none', 'cri-RI-PMI-CQI ', 'cri-RI-i1', 'cri-RI-i1-CQI', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR' or 'cri-RI-LI-PMI-CQI'. The CSI framework was introduced in NR Rel 15, and further enhanced in Rel 16, Rel 17 and Rel 18 to facilitate the inclusion of codebook enhancements and related signalling capabilities. As specified in NR standard, the CSI feedback report may be encoded and transmitted as 2 parts. If the reportQuantity is configured with one of the values 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR' or 'ssb-Index-SINR', or 'cri-RSRP-Index', 'ssb-Index-RSRP-Index', 'cri-SINR-Index', 'ssb-Index-SINR- Index', 'tdcp', the CSI feedback may consist of a single part. For all other cases, a second part is formed by the UE and transmitted to the gNB. While the structure and reporting requirements of PMI can vary with the selected codebook type being Type I, Type II, Enhanced Type II, Further Enhanced Type II Port Selection CSI, Enhanced Type II for CJT, Further Enhanced Type II Port Selection for CJT, Enhanced Type II for predicted PMI and Further Enhanced Type II Port Selection, the basic CSI information like CSI-RS resource indicator, CRI (if reported), rank indicator, RI (if reported), and channel quality indicator, CQI (for the first codeword if RI > 4) may be reported in Part 1. It may be noted that Part 1 may also contain additional information depending on the type of CSI codebook. On the other hand, CSI report Part 2 comprises the precoding matrix indicator, PMI and layer indicator, LI (if reported) along with the CQI for the second codeword (if reported for RI > 4). The CSI Part 1 has a fixed payload size and is also used to identify the number of information bits in Part 2. Also, Part 1will be transmitted in its entirety before Part 2. In NR (up to Rel-18), CRI reporting is supported for!CSI-RS resources with CSI-RS ports per resource limited to 16. Accordingly, a UE can be configuredwith either ! = 2 CSI-RS resources having 16 CSI-RS ports per resource or 2 <! ≤ 8 CSI-RS resources having 8 CSI-RS ports per resource. Clearly, CRIreporting is limited to Type I SP and Type I MP codebooks and is also not supported for 32 port resources in the earlier releases. Another key aspect is that a UE is allowed to report a single CRI alone in regular HBF deployments aside from Rel- 17 NCJT that supports multi-CRIs. For earlier releases up to Rel-18 the standard specifies that except for a CSI-ReportConfig configured with reportQuantity set to 'cri-RI-PMI-CQI' and codebookType set to 'typeII-CJT-r18', 'typeII-CJT- PortSelection-r18', 'typeII-Doppler-r18', or 'typeII-Doppler-PortSelection-r18', if the UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RSRP', 'cri-RI-PMI-CQI ', 'cri-RI-i1', 'cri-RI-i1-CQI', 'cri- RI-CQI', 'cri-RI-LI-PMI-CQI', 'cri-SINR', or 'cri-SINR- Index ', and!> 1 resources are configured in the corresponding resource set for channel measurement, then the UE shall derive the CSI parameters other than CRI conditioned on the reported CRI. Notedly, CRI k (k ≥ 0) corresponds to the configured (k+1)thentry of associated nzp-CSI-RS-Resources in the corresponding NZP-CSI-RS-ResourceSet for channel measurement, and (k+1)thentry of associated csi-IM-Resource in the corresponding csi-IM-ResourceSet (if configured) or (k+1)thentry of associated nzp-CSI-RS-Resources in the corresponding NZP-CSI-RS- ResourceSet (if reportQuantity set to 'cri-SINR' or 'cri-SINR-Index') for interference measurement. In a realistic network, it is quite generic for a gNB to schedule multiple CSI reports for various reasons, such as to gain a comprehensive channel understanding, enhance user experience, optimize network resource allocation, improve MIMO beam management strategies, manage a variety of report configurations (P, SP and AP time measurements) and even offer robustness in CSI reporting through redundancy. Clearly, CSI omission is quite vital when a UE is configured to send multiple CSI reports on PUSCH. When multiple reports are triggered simultaneously, a UE follows the priority list set by the network to decide which report to send first. The highest priority report is sent immediately, while lower- priority reports may be delayed or dropped. In certain cases, a UE may combine certain types of overlapping CSI reports into a single transmission, depending on the network configuration and UE capabilities. With UCI omission, CSI feedback may be delayed or skipped, potentially affecting how the gNBs optimizes the network (e.g., beamforming or scheduling decisions). However, this trade-off is acceptable when data transmission is a priority, and the network can still operate efficiently with intermittent CSI reports. As the choice of priority rule impacts the gathered channel information and helps gNB to make more informed decisions that lead to better network performance and user satisfaction, it is very critical to implement the right rule that takes into consideration every guiding factor. The priority rules supported in legacy releases up to Rel 18 is as explained. For two overlapping PUSCHs, the priority rules are currently applied for physical channels with same priority index (according to clause 9 in TS 38.213) if a UE is not configured with sTx-2Panel or a UE is configured by higher layer parameter PDCCH-Config that contains two different values of coresetPoolIndex in different ControlResourceSet in the active DL BWP and the UE is configured with sTx- 2Panel and the two overlapping PUSCHs are associated with same value of coresetPoolIndex. Accordingly, CSI reports are associated with a priority value, Pri$%&'(), *, +, -) = 2 ∙ 03455! ∙ 6! ∙ ) + 03455! ∙ 6! ∙ * + 6! ∙ + + -where,· ) = 0 for aperiodic CSI reports to be carried on PUSCH ) = 1 for semi-persistent CSI reports to be carried on PUSCH, ) = 2 for semi-persistent CSIreports to be carried on PUCCH and ) = 3 for periodic CSI reports to be carriedon PUCCH;· * = 0 for CSI reports carrying L1-RSRP or L1-SINR and * = 1 for CSIreports not carrying L1-RSRP or L1-SINR; · + is the serving cell index and 03455!is the value of the higher layer parameter maxNrofServingCells; (for a CSI report configured with LTM-CSI- ReportConfig, c is the serving cell index value where the report configuration is configured). · s is the reportConfigID and 6!is the value of the higher layer parameter maxNrofCSI-ReportConfigurations. (for a CSI report configured with LTM-CSI- ReportConfig, s is the LTM-CSI-ReportConfigID and Ms is the value of the higher layer parameter maxNrofLTM-CSI-ReportConfigurations). A first CSI report is said to have priority over second CSI report if the associatedPri$%&'(), *, +, -) value is lower for the first report than for the second report. TwoCSI reports are said to collide if the time occupancy of the physical channels scheduled to carry the CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier, in which case the priority rules are applied. In the extension of CRI-based CSI reporting for up to 128 CSI-RS ports in Rel-19, it has been discussed that a UE may be configured to measure KS >1 NZP CSI-RS resources with equal number of ports, with up to 32 ports per NZP CSI-RS resource. Also agreed is that the UE may be configured to report multiple CSI channel measurement reports (CMRs) carrying information pertaining to M each of CRIs, RIs, PMIs and CQIs (quadruplets) in one CSI reporting instance. M is agreed to have a value equal to min (4, KS) when Rel-15 Type I codebook is configured, and 2 when Rel-16 eType II codebook is configured. The Rel-19 CRI-based CSI reporting is proposed to support AP, P and SP CSI for Type I SP codebook, whereas AP and SP CSI on PUSCH can be configured for eType II SP codebook. In line with this extension, certain key agreements have been made in 3GPP RAN1 meetings as follows to realize the feature enhancement. For the 3GPP Release 19 CRI-based channel state information (CSI) refinement supporting up to 128 CSI-RS ports and applicable to aperiodic CSI (A- CSI) reporting, the network configures the user equipment (UE) with parameters M and MR, where MRis less than M and represents the subset of CSI-RS resources that are non-reported. Specifically, from KS configured CSI-RS resources, the network configures MRresources via higher-layer Radio Resource Control (RRC) signaling, which the UE excludes from reporting, while reporting the remaining (M–MR) CRIs along with associated channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and, if applicable, layer indicator (LI). The agreed values for MRallow it to be 1 or 2 for Release 15 Type I codebooks, and 1 for Release 16 enhanced Type II codebooks. Regarding uplink control information (UCI) omission for CSI Part 1, the UE must either report Part 1 entirely or drop it entirely following a packing order that prioritizes CSI Part 1 associated with the first configured measurement report among the non-reported MR CRIs, progressing through to the CSI Part 1 of the (M– MR)threported CRI. For CSI Part 2 omission, excluding the highest priority 0 group (G0), the network defines a sequence of 2M consecutive priority levels related to the M CRIs including both reported and non-reported MR CRIs wherein group 1 (G1) and group 2 (G2) PMI components for each configured measurement report are ordered from the first to the last configured measurement report. This ordering is similarly applied for even and odd subbands for Type I single-panel implementations. Importantly, legacy design is preserved for wideband (G0) and the PMI components (G1 and G2), enabling backward compatibility. These agreements provide a flexible framework for uplink CSI feedback omission and packing under constrained resources, reflecting an advancement over prior releases by accommodating multiple CRIs per report and enabling efficient prioritization of feedback components to optimize network performance. In 5G New Radio (NR), channel state information (CSI) is obtained at the user equipment (UE) by measuring downlink pilot signals referred to as CSI reference signals (CSI-RS), which are configured by the base station (gNB). The UE quantizes the estimated channel parameters and reports them back to the gNB through uplink control information (UCI). To enable efficient closed-loop communication, the gNB configures the UE with one or more CSI report configurations, each corresponding to a set of CSI-RS resources over which the UE performs channel measurements. CSI feedback reporting supports multiple scheduling methods, including periodic, semi-persistent, and aperiodic reporting, triggered via higher-layer signalling or downlink control information (DCI). Given the increasing complexity and volume of CSI feedback particularly with multiple configured CSI reports efficient feedback omission strategies are essential. The existing NR frameworks transmit CSI feedback in two parts, with Part 1 containing essential wideband information always sent fully, and Part 2 containing more detailed beam-specific parameters allowing for selective omission to fit the CSI payload within constrained uplink resources. Figure 2 illustrates a proposed CSI framework sequence flow (200) for supporting enhanced M CRI based CSI reporting for multiple CSI reports supporting up to 32 ports per NZP CSI-RS resource according to one embodiment of the present invention. Aspects of the present invention provide techniques for integrating the priority levels of multiple CSI reports with the Rel-19 uplink control information (UCI) packing order, including the handling of 2M consecutive priority levels associated with M CRIs. Further, the invention introduces methods to enhance the determination of priority order for CSI reports containing multiple CRIs by explicitly incorporating the value of M into the decision criteria and priority handling process. At step 215, the gNB (205) configures the UE (210) with a plurality of CSI reporting configurations, each configuration being associated with a plurality of transmission resources. In particular, the gNB may configure multiple CSI reports each comprising a set of CSI-RS resource indicator (CRI) measurements, wherein each CRI is associated with one or more CSI-RS resources and ports. The CSI reporting configuration may support multiple CRIs (M) to be included in a report and optionally permit non-reported CRIs (MR) to be indicated for omission handling. At step 220, the gNB triggers CSI reporting by the UE for CB based CRI CSI agreeing with the configuration settings, if trigger based semi-persistent or aperiodic reporting is configured or else the UE follows configured reporting periodicity. In some embodiments, the gNB may instruct the UE to multiple a subset of CSI reports based on the available resources and configured periodicities. At step 225, the UE performs channel measurements on the received reference signals corresponding to the configured CSI-RS resources. Based on such measurements, the UE generates CSI feedback including one or more of CRIs, rank indicators (RIs), precoding matrix indicators (PMIs), and channel quality indicators (CQIs). In one aspect, the UE determines a priority value for each CSI report as a function of either (i) the number of CRIs (M) configured to be reported, (ii) the number of non-reported CRIs (MR), or (iii) a combination of both. The priority rules may be applied according to different methods, such that CSI feedback corresponding to higher-priority CRIs is retained in the event of a collision or omission. At step 230, the UE transmits CSI feedback to the gNB 205. In one embodiment, the CSI feedback is structured into two parts: a Part 1 comprising CRIs, RIs, and CQIs, and a Part 2 comprising PMIs and additional CQIs. Under omission conditions caused by uplink control information (UCI) constraints, Part 1 is transmitted in its entirety before omitting Part 2, thereby ensuring delivery of the most essential CSI information. In some embodiments, the UE applies Rel-19 uplink control information packing rules and integrates the determined priority values with the UCI packing order. In further embodiments, prioritization among CRIs within the reported M subset or non-reported MRsubset is based on quality metrics such as CRI-SINR, CRI-RSRP, resource-specific RI, or resource-specific CQI. At step 235, the gNB receives and decodes the transmitted CSI feedback. The decoded feedback is then used to optimize beamforming, link adaptation, and scheduling operations in the network. By applying the disclosed priority methods, the system ensures that at least a subset of the highest-priority CRIs is reported even under uplink resource limitations, thereby improving reliability and maintaining backward compatibility with legacy priority rules. Figure 3 illustrates an example illustration of UCI packing order and priority levels for a single CSI report having M CRIs in a single CSI reporting instance (300). In other embodiment, the packing order and priority levels of M-CRI-based CSI reports, as aligned with Rel-19 standardization. The M CRI based CSI report packing order and priority levels for a single CSI report, as agreed in Rel-19 is detailed. The priority of each reported element of varying indices packed in different groups can follow the legacy packing specific to the choice of codebook type by following the priority value Pri(l,i,f). However, this priority needs to be modified with changes to level of multiple CSI reports. Invention provides two methods to integrate the CSI report priority level criterion of multiple CSI reports with the Rel-19 agreed UCI packing order and the 2M consecutive priority levels of M CRIs. Both the methods are coined without disrupting the existing priority orders of packing M CRI. However, the multitude possibilities of packing and priority for M CRIs, excluding the agreed choice, are not excluded from being considered with this report priority with suitable changes. Figure 4 illustrates an example illustration of first method of UCI packing order and priority levels for multiple CSI reports having M CRIs in every CSI reporting instance (400), according to one embodiment of the present invention. It provides a simplified view of how priority levels are assigned to multiple CSI reports in the first method. Each CSI report is given 2M consecutive priority levels, where M is the number of CRIs included in that report. The figure shows how these levels are distributed across reporting groups: · Group 0 or wideband CSI covering all M CRIs. · Group 1 or even sub-bands, and Group 2 or odd sub-bands. · Within each group, priorities are further assigned to CRIs based on whether they are reported CRIs (from the M set) or non-reported CRIs (from the MR set). In a first method, CMRs of M CRIs associated with a single CSI reporting instance are packed such that complete M CRIs of a first CSI report are packed prior to M CRIs of subsequent CSI reports, and wherein applying the unified packing order or priority order for Part 2 subband CSI, for priority levels greater than zero, further comprises linking 2M consecutive priority levels of M CRIs with the priority order of CSI reports such that complete M CRIs of a first CSI report are assigned a higher priority than M CRIs of subsequent CSI reports. Figure 5 illustrate priority reporting levels in 5G NR for configure n CSI reports with M CRIs aiding Part 2 CSI omission using first method (500). In this embodiment, the system supports reporting of NRep CSI reports, each configured to include M CSI-RS resource indicators (CRIs). The figure demonstrates how the priority levels are distributed across CSI reports to aid omission handling of Part 2 CSI feedback. Here, the priority rules for n CSI reports may follow the enhanced priority rule proposed further in this disclosure so as to achieve an improved omission criterion, however application of the legacy priority rules are not precluded. The first method is a straightforward approach of linking the two priorities. However, one of the shortcomings of this method is that the network will have to endure any performance degradation due to all the missed CSI reports (which are missed entirely) if CSI omissions occur. Clearly, with this method of linking, it is desirable to modify the determination of priority order for CSI with M CRIs by accounting for the value of M in the decision criteria and priority level handling action so as to improve the packing efficiency. As illustrated in FIG. 5, the grouping and assignment of priorities ensure that the first CSI report has its M CRIs mapped to the lowest (i.e., highest-priority) values, while subsequent CSI reports occupy progressively lower-priority positions. The method provides a straightforward approach for integrating CRI prioritization with Rel-19 omission handling. However, a limitation of this method is that if omission occurs, an entire CSI report may be dropped, resulting in potential performance degradation as all of its M CRIs are lost simultaneously. This drawback highlights the desirability of enhancing the determination of priority order by incorporating the parameter M directly into the decision criteria and priority level handling action. Such an enhancement can improve packing efficiency and ensure that omission handling better preserves the most critical CRIs across multiple reports. Figure 6 illustrates an example illustration of second method of UCI packing order and priority levels for multiple CSI reports having M CRIs in every CSI reporting instance (600), according to one embodiment of the present invention. It shows an example of how priority levels are assigned to multiple CSI reports in the second method. At the top, Group 0 / wideband CSI) is always given the highest priority (Priority 0) for all reports. After that, the non-reported CRIs (MR) of each CSI report are given the next set of priority levels, starting with Group 1 / even sub- bands and Group 2 / odd sub-bands, from the first non-reported CRI to the last one. Only after all non-reported CRIs are prioritized do the reported CRIs (M–MR) get their priority levels, again divided into Group 1 and Group 2 for each report. In this way, non-reported MRCRIs of all CSI reports always have a higher priority than the remaining M-MR CRIs of even the first report, ensuring that the most critical CRIs are preserved first when CSI omission occurs. In a corresponding second method applied to Part 2 subband CSI for priority levels greater than zero, 2M consecutive priority levels of M CRIs associated with a single CSI reporting instance are linked with the priority order of CSI reports such that the complete set of MR CRIs of a first CSI report are assigned higher priority than the MR CRIs of subsequent CSI reports, and the remaining (M–MR) CRIs of the first CSI report are assigned higher priority than the (M–MR) CRIs of subsequent CSI reports. The second method interleaves the packing of CSI reports in a way that the priority orders of CSI reports repeat themselves for non-configured and configured reports. A significant advantage here is that the network can ensure the reporting of at least a few CRI CMRs for all CSI reports even if CSI omissions occur. Clearly, with this method of linking, it is desirable to modify the determination of priority order for CSI with M CRIs by accounting for the value of MR in the decision criteria and priority level handling action so as to improve the packing efficiency. Figure 7 illustrates Priority reporting levels in 5G NR for configure n CSI reports with M CRIs aiding Part 2 CSI omission using second method (700), according to one embodiment of the present invention. It may be noted that MR CRIs of all CSI reports have a priority higher than the remaining M-MRCRIs of even the first report. Here, the priority rules for CSI reports may follow the enhanced rule proposed in this invention for an improved omission criterion, yet the application of legacy or other priority rules are not precluded. As per the current understanding, the support for configured MRis a UE capability and hence the method is applicable if MR is configured. In an aspect of the implementation of this method, if MR is not configured, MR may also be predefined to be 1 if agreed by the UE and gNB. In one embodiment, the unified packing order or priority order for Part 2 wideband CSI at priority level 0 may follow a first method of packing in which CMRs associated with CSI reports having M CRIs in a single CSI reporting instance are packed such that the complete M CRIs of a first CSI report is packed prior to M CRIs of subsequent CSI reports. In one embodiment, the unified packing order or priority order for Part 2 wideband CSI at priority level 0 may follow a first method of packing in which CMRs associated with CSI reports having M CRIs in a single CSI reporting instance are packed such that the complete set of MR CRIs of a first CSI report is packed prior to the MRCRIs of subsequent CSI reports, and the remaining (M–MR) CRIs of the first CSI report are subsequently packed prior to the (M–MR) CRIs of the subsequent CSI reports. In one alternative, the first method or the second method of linking priority levels of M CRIs with the priority order of nthreport, for priority 0 or priority >0, may be selected as a predefined static method by the network. In another alternative, the two methods may be two options which may be dynamically or semi-statically selected by the network and UE. Either alternatives may be configured by the network or selected as a UE capability. In all embodiments, the value of MRis configured by a higher layer parameter, and if configured then the non-reported or non-configured CRIs are defined by (M–MR) CRIs, else non-reported or non- configured CRIs are defined by (M) CRIs. In all embodiments, wherein 2NRep is the lowest priority and the CSI report n corresponds to the CSI report with the nthsmallest priority value among the NRep CSI reports configured to be carried on the PUSCH, either using first method or second method of priority order in any derived combinations for the priority 0 and the priority other than 0 options, is defined either using the legacy priority rule or the new priority rules in the embodiments. In an example method, for the first method of packing order, without excluding any other methods, if a CSI report ; is configured with M CRIs, the value of which is indicated by a higher layer parameter, for other than Priority 0, the 26 consecutive priority levels of the nthreport, within the multiple NRep CSI reports is defined as: · -Part 2 Group 1 / even subbands of the first configured CSI-RS resource for CMR among the non-reported 6?CRIs. · -Part 2 Group 2 / odd subbands of the first configured CSI-RS resource for CMR among the non-reported 6?CRIs. · -… · -Part 2 Group 1 / even subbands of the last configured CSI-RS resource for channel measurement among the non-reported 6?CRIs. · -Part 2 Group 2 / odd subbands of the last configured CSI-RS resource for channel measurement among the non-reported 6?CRIs. · -Part 2 Group 1 / even subbands of the first reported CRI. · -Part 2 Group 2 / odd subbands of the first reported CRI. · -… ·-Part 2 Group 1 / even subbands of the (6 − 6?)-th reported CRI.· -Part 2 Group 2 / odd subbands of the (6 − 6?)-th reported CRI.And, in an example method, for the first method of packing order, without excluding any other methods, if a CSI report ; is configured with M CRIs, the value of which is indicated by a higher layer parameter, the UCI packing of the nthreport within the multiple NRep CSI reports for the highest priority, Priority 0, with Group 0 / wideband for all M CRIs is defined as: · -Part 2 Group 0 / wideband of the first configured CSI-RS resource for CMR among the non-reported 6?CRIs. · -… · -Part 2 Group 0 / wideband of the last configured CSI-RS resource for channel measurement among the non-reported 6?CRIs. · -Part 2 Group 0 / wideband of the first reported CRI. · -… ·-Part 2 Group 0 / wideband of the (6 − 6?)-th reported CRI.The packing order of UCI bits for CSI Part 2 with its CQI, LI, PMI values, is further defined as: · Wideband CQI for the second TB for the first configured CMR among the non-reported 6?CRIs, if present and reported. · LI for the first configured CMR among the non-reported 6?CRIs, if reported. · Wideband PMI information field X1, from left to right as in legacy mapping, for the first configured CMR the non-reported 6?CRIs, if reported. · Wideband PMI information field X2, from left to right as in legacy mapping, for the first configured CMR among the non-reported 6?CRIs, or codebook index for 2 antenna ports for the first configured CMR among the non-reported 6?CRIs, if widebandPMI is configured and if reported. · … · Wideband CQI for the second TB for the last configured (6?th) CMR among the non-reported 6?CRIs, if present and reported. · LI for the last configured (6?th) CMR among the non-reported 6?CRIs, if reported. · Wideband PMI information field X1, from left to right as in legacy mapping, for the last configured (6?th) CMR among the non-reported 6?CRIs, if reported. · Wideband PMI information field X2, from left to right as in legacy mapping, for the last configured (6?th) CMR among the non-reported 6?CRIs, or codebook index for 2 antenna ports for the first configured CMR among the non-reported 6?CRIs, if widebandPMI is configured and if reported. · … · Wideband CQI for the second TB for the first reported CRI, if present and reported. · LI for the first reported CRI, if reported. · Wideband PMI information field X1, from left to right as in legacy mapping, for the first reported CRI, if reported. · Wideband PMI information field X2, from left to right as in legacy mapping, for the first reported CRI, or codebook index for 2 antenna ports for the first reported CRI, if widebandPMI is configured and if reported. · … ·Wideband CQI for the second TB for the (6 − 6?)-th reported CRI, ifpresent and reported. ·LI for the (6 − 6?)-th reported CRI, if reported.· Wideband PMI information field X1, from left to right as in legacy mapping, for the (6 − 6?)-th reported CRI, if reported.· Wideband PMI information field X2, from left to right as in legacy mapping, for the (6 − 6?)-th reported CRI, or codebook index for 2 antenna portsfor the (6 − 6?)-th reported CRI, if widebandPMI is configured and ifreported. In all embodiments, the subband CSIs of even / odd subbands are applied if the codebook type is configured as typeI-SinglePanel, and Group 1 / Group 2 CSI are applied if the codebook type is configured as typeII-r16. When M CRI based CSI reporting is introduced, the priority criteria associated with the nthreport itself may be redefined to accommodate this inclusion. Accordingly, this invention also provides a method to enhance the determination of priority order for CSI with M CRIs by accounting for the multi-CRI aspect in the decision criteria and priority level handling action. Accordingly, for two overlapping PUSCHs, the updated priority rules may be applied for physical channels with same priority index (according to clause 9 in TS 38.213) if a UE is not configured with sTx-2Panel or a UE is configured by higher layer parameter PDCCH-Config that contains two different values of coresetPoolIndex in different ControlResourceSet in the active DL BWP and the UE is configured with sTx- 2Panel and the two overlapping PUSCHs are associated with same value of coresetPoolIndex. In one aspect, the modification of the priority value includes incorporating multi-beam characteristics, such as the number of reported CRIs (M), into the priority rule as described below.CSI reports are associated with a priority value Pri$%&'(), *, +, -, A, 6),Pri$%&'(), *, +, -, A, 6) = 2 ∙ 03455! ∙ 6! ∙ 6B ∙ ) + 03455! ∙ 6! ∙ 6B ∙ * +6! ∙ 6B ∙ + + - + 6! ∙ 6 ∙ Awhere,· ) = 0 for aperiodic CSI reports to be carried on PUSCH ) = 1 for semi-persistent CSI reports to be carried on PUSCH, ) = 2 for semi-persistent CSIreports to be carried on PUCCH and ) = 2 for periodic CSI reports to be carriedon PUCCH;· * = 0 for CSI reports carrying L1-RSRP or L1-SINR and * = 1 for CSIreports not carrying L1-RSRP or L1-SINR; · + is the serving cell index and 03455!is the value of the higher layer parameter maxNrofServingCells; (for a CSI report configured with LTM-CSI- ReportConfig, c is the serving cell index value where the report configuration is configured). · s is the reportConfigID and 6!is the value of the higher layer parameter maxNrofCSI-ReportConfigurations.

(6B= 1 for legacy CSI reports up to Rel 18 and 6B= 4 in Rel 19). M is the number of CRIs present in a specific CSI report; In another aspect, the priority value modifications comprise of including the multi-beam characteristics, such as 6?non-reported CRIs, in the priority rule as explained,CSI reports are associated with a priority value Pri$%&'(), *, +, -, A, 6?),Pri$%&'(), *, +, -, A, 6?) = 2 ∙ 03455! ∙ 6! ∙ 6B ∙ ) + 03455! ∙ 6! ∙ 6B ∙ * +6! ∙ 6B ∙ + + - + 6! ∙ 6? ∙ Awhere,· ) = 0 for aperiodic CSI reports to be carried on PUSCH ) = 1 for semi-persistent CSI reports to be carried on PUSCH, ) = 2 for semi-persistent CSIreports to be carried on PUCCH and ) = 2 for periodic CSI reports to be carriedon PUCCH;· * = 0 for CSI reports carrying L1-RSRP or L1-SINR and * = 1 for CSIreports not carrying L1-RSRP or L1-SINR; · + is the serving cell index and 03455!is the value of the higher layer parameter maxNrofServingCells; (for a CSI report configured with LTM-CSI- ReportConfig, c is the serving cell index value where the report configuration is configured). · s is the reportConfigID and 6!is the value of the higher layer parameter maxNrofCSI-ReportConfigurations.

(6B= 1 for legacy CSI reports up to Rel 18 and 6B= 4 in Rel 19). MRis the number of non-reported CRIs present in a specific CSI report; The major changes of the disclosed method from the legacy priority rule that was applied to pre-Rel 18 CSI reporting is explained as follows; The legacy priority value determined by the term 2 ∙ 03455! ∙ 6! ∙ ) +03455! ∙ 6! ∙ * + 6! ∙ + is weighted with an additional term 6B, where 6B is themaximum number of CRIs allowed to be configured to the UE irrespective of the codebook type supported. This ensures that the legacy priority rules are preserved for 'periodic', 'semi-persistent' and 'aperiodic' reporting as well as for higher priority L1-RSRP or L1-SINR reporting. This also ensures that the legacy rule ofhigher cell ids having lower priority (higher Pri$%&'(), *, +, -, A, 6?)) ismaintained even with the suggested changes. Inclusion of additional terms 6!∙6 ∙ A or 6! ∙ 6? ∙ A ensures that the report priority is determined by a uniquevalue determined jointly from report config id s and number of CRIs in the CSI report. This invention also proposes a third method, wherein the priority rule comprises of a rule determined as a function of M (the number of CRIs configured to be reported in a CSI report) and MR(the number of non-reported CRIs configured to be reported in a CSI report) aligned with the method of proposal presented in the invention. The priority value modifications comprise of including the multi-beam characteristics, such as M reported CRIs and 6?non-reported CRIs, in the priority rule as explained, CSI reports are associated with a priority valuePri$%&'(), *, +, -, A, 6, 6?),Pri$%&'(), *, +, -, A, 6, 6?)= 2 ∙ 03455! ∙ 6! ∙ 6B ∙ ) + 03455! ∙ 6! ∙ 6B ∙ * + 6! ∙ 6B ∙ + + -+ 6! ∙ (6 − 6?) ∙ Awhere,· ) = 0 for aperiodic CSI reports to be carried on PUSCH ) = 1 for semi-persistent CSI reports to be carried on PUSCH, ) = 2 for semi-persistent CSIreports to be carried on PUCCH and ) = 2 for periodic CSI reports to be carriedon PUCCH;· * = 0 for CSI reports carrying L1-RSRP or L1-SINR and * = 1 for CSIreports not carrying L1-RSRP or L1-SINR; · + is the serving cell index and 03455!is the value of the higher layer parameter maxNrofServingCells; (for a CSI report configured with LTM-CSI- ReportConfig, c is the serving cell index value where the report configuration is configured). · s is the reportConfigID and 6!is the value of the higher layer parameter maxNrofCSI-ReportConfigurations. (for a CSI report configured with LTM-CSI- ReportConfig, s is the LTM-CSI-ReportConfigID and Ms is the value of the higher layer parameter maxNrofLTM-CSI-ReportConfigurations). · m = 0 for non-M CRI based CSI reports (legacy CSI reports up to Rel 18) and m = 1 for M CRI based CSI reports.6Bis the maximum number of CRIs allowed. (6B= 1 for legacy CSI reports up to Rel 18 and 6B= 4 in Rel 19). M is the number of CRIs present in a specific CSI report. MR is the number of non- reported CRIs present in a specific CSI report; A first CSI report is said to have priority over second CSI report if the associated Pri$%&'(), *, +, -, A, 6) or Pri$%&'(), *, +, -, A, 6?) orPri$%&'(), *, +, -, A, 6, 6?) value is lower for the first report than for the second By way of example, two CSI reports are said to collide if the time occupancy of the physical channels scheduled to carry the CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier. When a UE is configured to transmit two colliding CSI reports, 1. if y values are different between the two CSI reports, the following rules apply except for the case when one of the y value is 2 and the other y value is 3 (for CSI reports transmitted on PUSCH, as described in Clause 5.2.3; for CSI reports transmitted on PUCCH, as described in Clause 5.2.4): 2. The CSI report with higher Pri$%&'(), *, +, -, A, 6) orPri$%&'(), *, +, -, A, 6?) or Pri$%&'(), *, +, -, A, 6, 6?) value shall not be sent bythe UE. 3. otherwise, the two CSI reports are multiplexed or either is dropped based on the priority values, as described in Clause 9.2.5.2 in [6, TS 38.213]. A CSI report configured with LTM-CSI-ReportConfig has a higher priority over all CSI report(s) configured with CSI-ReportConfig irrespective ofPri$%&'(), *, +, -, A, 6) or Pri$%&'(), *, +, -, A, 6?) or Pri$%&'(), *, +, -, A, 6, 6?)value in case of collision with CSI report(s) configured with CSI-ReportConfig. In some embodiments of the method, the parameter 6Bmay be fixed to 4 which is the recommended value of Rel 19, to render the priority rules equally applicable for all releases, without any updation. Accordingly, the priority rule may be fixed for Rel 19 as;CSI reports are associated with a priority value Pri$%&'(), *, +, -, A, 6),Pri$%&'(), *, +, -, A, 6) = 2 ∙ 4 ∙ 03455! ∙ 6! ∙ ) + 4 ∙ 03455! ∙ 6! ∙ * + 4 ∙ 6! ∙ + +- + 6! ∙ 6 ∙ ACSI reports are associated with a priority value Pri$%&'(), *, +, -, A, 6?),Pri$%&'(), *, +, -, A, 6?) = 2 ∙ 4 ∙ 03455! ∙ 6! ∙ ) + 4 ∙ 03455! ∙ 6! ∙ * + 4 ∙ 6! ∙ + +- + 6! ∙ 6? ∙ AThe proposed modifications in the disclosed methods of assigning priority rules for CSI reports allow to factor multi-CRIs in the priority rule to accommodate Rel-19 changes yet ensures that the priority order is intact and backward compatible when m = 0. In scenarios where it is desirable to associate maxNrofServingCells and maxNrofCSI-ReportConfigurations with either M (the number of CRIs present in a specific CSI report) or MR (the maximum number of non-reported CRIs present in a specific CSI report) or both, priority rules for CSI reports may be generated by conditioning m with maxNrofServingCells and maxNrofCSI-ReportConfigurations along with M or MR or both. The present invention relates to the modification of legacy priority rules for CSI reports by incorporating additional rules that account for multi-beam and multi-CRI attributes, including factors such as the maximum number of beams, and the number of configured and non-configured beams within a report, while not precluding alternative approaches for weighting these factors in determining priority. Although the invention primarily applies to CRI-based reporting, it is equally applicable to non-CRI reporting scenarios with m = 0 and 6B= 1, inwhich case the legacy priority value Pri$%&'(), *, +, -) implicitly applies.The proposed modifications in the disclosed methods allows to apply any packing order / priority order for priority 0 with any packing order / priority order for priority other than 0 with any priority value calculation, not excluding the legacy calculation, in any combination. Furthermore, the invention is suitable for deployment with large antenna arrays without limitation on horizontal or vertical antenna dimensions, and is applicable across cellular frequency ranges including FR1, FR2, FR3, and the THz spectrum, while not excluding applicability to other carrier frequencies. FIG. 8 illustrates a block diagram of a system for reporting channel state information (CSI) in a wireless communication system (800), in accordance with one embodiment of the present invention. The system comprises a user equipment (UE) and a base station (gNB), each including functional components operative to enable prioritized CSI reporting and network optimization. The UE comprises a transceiver module configured to receive downlink reference signals (CSI-RS) transmitted by the base station. The CSI-RS includes configuration information for a plurality of CSI reports, wherein at least one CSI report is configured to include multiple CSI-RS resource indicators (CRIs), each CRI being associated with one or more CSI-RS ports. The UE further comprises a channel measurement module operative to perform measurements on the received reference signals. The measurement results are provided to a CSI report generator, which produces CSI feedback comprising the configured CRIs together with at least one of: rank indicators (RIs), precoding matrix indicators (PMIs), and channel quality indicators (CQIs). A priority determination module assigns priority values to the CSI reports based on at least one of: (i) a number of reported CRIs (M), or (ii) a number of non- reported CRIs (MR). Under resource limitations that result in collisions or omissions, a feedback transmission controller ensures that CSI reports or portions thereof having higher priority values are retained for transmission, while lower- priority reports or portions may be omitted. The operations of the UE are supported by a processor and memory subsystem operative to execute control logic and store CSI-related configurations. The base station comprises a configuration module operative to configure the UE with CSI reporting resources, including CSI-RS transmission parameters and reporting configurations. A reference signal transmission module transmits the CSI-RS to the UE for enabling channel measurements. The base station further comprises a CSI feedback receiver operative to receive prioritized CSI feedback transmitted by the UE. The received CSI feedback is processed by a beamforming and scheduling optimizer, which utilizes the prioritized CSI feedback to perform one or more of: link adaptation, beam management, and scheduling operations. These functions are coordinated by a processor and memory subsystem within the base station. As further shown in FIG. 8, the communication flow includes: (i) transmission of reference signals (CSI-RS) from the base station to the UE, and (ii) transmission of prioritized CSI feedback from the UE to the base station. A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other implementations are within the scope of the following claims.

The system as claimed in claim 18, wherein the UE applies a unified packing order for CSI Part 2 subband CSI, for priority level > 0, and packs CMRs associated with CSI reports having M CRIs in a single CSI reporting instance as either: assigns higher priority to all M CRIs of a first CSI report over M CRIs of subsequent CSI reports, or assigns higher priority to all MRCRIs of a first CSI report over MRCRIs of subsequent CSI reports, followed by assigning higher priority to (M–MR) CRIs of the first CSI report over (M–MR) CRIs of subsequent CSI reports.
22. The system as claimed in claims 20 or 21, wherein the selection of the packing order is static, semi-static, or dynamic based on UE capability or network configuration.
23. The system as claimed in claims 20 or 21, wherein the CSI Part 2 packing order further includes PMI components grouped by CRI priority levels, with higher priority assigned to CRIs with better channel quality metrics.
24. The system as claimed in claim 18, wherein the priority order for the CRIs reported in CSI Part 2 of a single CSI reporting instance is adjusted such that: MR CRIs are ordered from higher to lower priority based on a configured order of MR; and (M–MR) CRIs are ordered from higher to lower priority based on a channel quality metric selected from: CRI-SINR, CRI-RSRP, resource-specific CQI, or resource-specific RI.
25. The system as claimed in claim 18, wherein the UE applies a weighted omission strategy that retains high-quality CRIs even when lower-priority CSI reports are omitted.
26. The system as claimed in claim 18, wherein the priority rule supports CSI reporting in multi-TRP or multi-panel configurations by associating CRIs with spatial domains.
27. The system as claimed in claim 18, wherein the priority rule is used to schedule CSI reports across multiple uplink carriers in carrier aggregation scenarios.
28. A network node configured for managing channel state information (CSI) reporting in a wireless communication system, the network node comprising: a processor; a memory communicatively coupled to the processor; a storage medium storing instructions that, when executed by the processor, cause the network node to: transmit configuration information for a plurality of CSI reporting configurations to a user equipment (UE), each CSI reporting configuration being associated with a plurality of CSI reference signal (CSI-RS) resources; transmit reference signals corresponding to the plurality of CSI-RS resources to the UE; receive, from the UE, CSI feedback comprising a plurality of CSI measurement reports (CMRs), each CMR including at least one of: a CSI- RS resource indicator (CRI), a rank indicator (RI), a layer indicator (LI), a precoding matrix indicator (PMI), and a channel quality indicator (CQI); process the CSI feedback, the CSI feedback being prioritized by the UE in accordance with a priority rule based on at least one of: a number of reported CRIs (M), a number of non-reported CRIs (MR), or a combination of both the reported CRIs and the non-reported CRIs; and perform at least one of beamforming, link adaptation, scheduling, or resource allocation based on the prioritized CSI feedback, such that CSI reports having higher priority values are preserved when CSI omissions occur due to uplink resource limitations; anda network interface configured to enable wireless communication between the network node and the UE.
29. The network node as claimed in claim 28, wherein the processor is further configured to dynamically adjust CSI reporting schedules based on at least one of: a capability of the UE, a number of reported CRIs (M), a number of non-reported CRIs (MR), or prevailing network conditions, thereby optimizing uplink resource utilization and base station beamforming performance.
