DETAILED DESCRIPTION The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, algorithm, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims. Wireless devices may operate as defined by technical standards. For cellular telecommunications, the 3rd Generation Partnership Program (3GPP) defines communication techniques, including for reporting of channel state information (CSI). Channel state information (CSI) feedback is used in fifth generation (5G) NR (New Radio) systems to assist scheduling, link adaptation, precoding and spatial multiplexing operations for PDSCH (Physical Downlink Shared Channel) transmission. A CSI report is transmitted from user equipment (UE) to gNB (gNodeB) via physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH). The main components of a CSI report are: (1) a CSI Attorney Docket No.: AF9389-PCT (31517-3585) Reference Signals (CSI-RS) resource indicator (CRI) that indicates a CSI-RS resource which is selected by the UE and used for computation of other CSI components in the CSI report; (2) a rank indicator (RI) that includes information on the number of spatial layers (rank) recommended by the UE for PDSCH; (3) a precoding matrix indicator (PMI) that includes information on the precoding matrix recommended by the UE for PDSCH; and (4) a channel quality indicator (CQI) that includes information on the modulation and coding scheme recommended by the UE for PDSCH. Performance of PDSCH (Physical Downlink Shared Channel) transmission in 5G NR (New Radio) cellular communication systems depends on the availability of Channel State Information (CSI) at the gNodeB (gNB). CSI feedback can be used to derive CSI, in this case User Equipment (UE) reports CSI to the gNB based on UE measurements of CSI Reference Signals (CSI-RS). Progress in active antenna arrays technology allows for producing antenna arrays with a large number of antenna ports for digital beamforming and spatial multiplexing of data streams. Existing commercial gNB antenna arrays support 64 antenna ports for transmission and reception. Hower, high costs of antenna arrays with a large number of antenna ports motivate research and development of antenna arrays with hybrid beamforming, where each antenna port is connected to multiple antenna elements using phase shifters. Thus, antenna arrays with hybrid beamforming use a combination of analog beamforming and digital beamforming. Due to technical constraints of analog beamforming, separate CSI-RS resources are commonly used for different analog beams. The current 3GPP NR specification supports reporting of CSI for a single CSI-RS resource selected by a UE in a single CSI report. The present disclosure provides enhancements for the 3GPP 5G NR physical layer specification targeting support of CSI for multiple CSI-RS resources in one CSI report. The present disclosure enables reporting of multiple CSI-RS resource indicators (CRIs) for UE selection of multiple CSI-RS resources, and enables multiplexing, prioritization, and dropping for CRI, Rank Indicator (RI), Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI) reporting corresponding to different CSI-RS resources. For a given CSI report, a UE is configured with K≥1 CSI-RS resources each corresponding to P≥1 CSI-RS ports in each CSI-RS resource. To determine CRI / RI / PMI / CQI for the CSI report, UE measures channel on the configured CSI-RS resources and CSI-RS ports. RI / PMI / CQI are calculated on the channel measured from CSI-RS resource indicated by CRI. CRI corresponds to ceil(log2(K)) bits reported in part 1 CSI in UCI (Uplink Control Attorney Docket No.: AF9389-PCT (31517-3585) Information). The CSI report is configured by using higher layer information element CSI- ReportConfig. In the current 5G NR specification, CRI is defined as an index of selected CSI- RS resource. For hybrid antenna arrays with both analog and digital beamforming, CSI reports for multiple CSI-RS resources corresponding to multiple analog beams may be needed. CSI with Multiple Sub-Configurations A gNB first transmits CSI-RS on set of CSI-RS resources, each corresponding to different CSI-RS resource index. UE receiving the CSI-RS on set of CSI-RS resources, performs measurement of the CSI-RS resources and computes CSI feedback that correspond to plurality of the CSI-RS resources that correspond to plurality of CRI. The computed CSI feedback bits are reported in a CSI report from the UE to the gNB. The CSI-RS in the set of CSI-RS resources may be transmitted by the gNB and used by the UE to perform measurement and computation of CSI feedback. The CSI report may be computed and sent by the UE that includes multiple CSI feedback for multiple CSI-RS resources corresponding to multiple CRI feedback. There may be individual CSI feedback for different CSI-RS resource each corresponding to different CRI. S > 1 sub-configurations {s1,s2,…,sS} can be configured for a UE for a CSI report. A CSI sub-configuration can be configured by using higher layer information element CSI-ReportSubConfig. A CSI sub- configuration with index s may include a list of Ks CSI-RS resources. In one or more embodiments of the present disclosure, if UE selects a CSI-RS resource with index kA for the CSI sub-configuration sA, UE shall not select the CSI-RS resource with index kAfor a CSI sub-configuration other than sA. Further, the selected CSI-RS resources {k1,k2,…,kS} order may be decided by the UE (e.g., in increasing order of signal power or channel quality or channel capacity on the corresponding CSI-RS resources). Alternatively, UE shall report CSI for CSI-RS resources {k1,k2,…,kS} in ascending order of CRI (or descending order of CRI). In case UE report CSI for CSI-RS resource in ascending (or descending) order of CRI, it is assumed gNB configures the CSI-RS resources in the prioritization order for which the gNB requests to potentially receive CSI. CSI with Multiple CSI Reports T > 1 CSI reports {t1,t2,…,tS} can be multiplexed in one UCI (Uplink Control Information) for CSI transmission. A CSI report with index t may include a list of KsCSI-RS resources. In one or more embodiments of the present disclosure, multiple CSI-RS resources are configured with the same list of CSI-RS resources. If UE selects a CSI-RS resource with index Attorney Docket No.: AF9389-PCT (31517-3585) kAfor the CSI sub-configuration sA, UE shall not select the CSI-RS resource with index kAfor a CSI sub-configuration other than sA. Reporting of Multiple CRIs In one or more embodiments of the present disclosure, L CRI values {l1,l2,…,lL} are reported by using a single bitfield. In one option, an index of combination is used for reporting of L CRI values with ceil(log2(C(L, K))) bits, where log2( ) is logarithm function with base 2, C(L, K) is the number of combinations of L indexes out of K indexes. Example for index of combination reporting can be found in 3GPP TS 38.214 (V16.2.0) Section 5.2.2.2.5 for reporting of index i1,6,l. In another option, L CRI values {l1,l2,…,lL} are reported by using bitmap with K bits, where the L bits equal to one indicating the indexes of selected CSI-RS resources and all remaining bits are set to zero. In one or more embodiments of the present disclosure, L CRI values {l1,l2,…,lL} are reported by using L bitfields with size of ceil(log2(K)) bits, where each bitfield correspond to an index of CSI-RS resource. Further, the selected CSI-RS resources {l1,l2,…,lL} order is decided by the UE (e.g., in increasing order of signal power or channel quality or channel capacity on the corresponding CSI-RS resources). Determination of the Number of Reported CRIs In one or more embodiments of the present disclosure, L CRI values {l1,l2,…,lL} are reported by the UE indicating selection of the corresponding CSI-RS resources {l1,l2,…,lL}. In one option, L is configured by higher layers per CSI report. Further, L can be configured by higher layers per CSI sub-configuration. In another option, gNB may indicate the number of CSI feedback, corresponding to L, in downlink control information (DCI) as part of the uplink scheduling grant for physical uplink shared channel (PUSCH) transmission. This may be enabled for semi-persistent CSI feedback or aperiodic CSI feedback that is being sent over PUSCH (by the UE). The DCI may carrier information that selects the CSI-RS resource set and the number of CSI feedback expected to be reported, L, for the indicated CSI-RS resource set. In case of semi-persistent (SP) CSI feedback, MAC control element (CE) transmission from the gNB may be sent to determine the number of CSI feedback expected to be reported, L, for SP-CSI feedback. In another option, gNB may indicate number of CSI feedback, corresponding to L, where UE is expected to report CSI feedback from a subset of CSI-RS resources (or equivalently subset of CRIs) from the CSI-RS resource set, in downlink control information Attorney Docket No.: AF9389-PCT (31517-3585) (DCI) as part of the uplink scheduling grant for physical uplink shared channel (PUSCH) transmission. The indication of subset of CSI-RS resources (or equivalently subset of CRIs) and number of CSI feedback allows gNB to receive CSI feedback for multiple CSI feedback correspond to multiple CRI in multiple CSI reporting instances. This is useful when UE capabilities limits the number of CSI reports that could be concurrently generated by the UE. For example, gNB can request to indicate 1 CSI feedback among all CSI-RS resources (and CRIs) in the first CSI reporting instance, and in the next CSI reporting instance gNB can request to indicate another 1 CSI feedback among all CSI-RS resources (and CRIs) excluding CSI-RS resource (and CRI) that was previously reported by the UE. This allows gNB to obtain multiple CSI feedback for multiple CRI across multiple CSI reporting instances. Alternatively, gNB can indicate total number of CSI feedback, L, and immediate number of CSI feedback, M, to be reported to the UE. UE then report M CSI feedback in each CSI reporting instance across L / M CSI reporting instances. Alternatively, instead of indication for subset selection of CSI-RS resource of a CSI- RS set in DCI or MAC-CE, gNB may indicate blacklist of CSI-RS resources among CSI-RS resources in the CSI-RS resource set of which the UE should not provide a report. In another option L is selected at the UE and reported in CSI part 1 (e.g., based on signal power or channel quality or channel capacity on the corresponding CSI-RS resources). The payload of CSI part 2 is determined according to the reported L value. Multiplexing, Priority Rules, and Dropping CSI reports, CSI sub-configurations have a specific priority in UCI (CSI part 1 or CSI part 2). Further, bitfields and / or groups of bitfields used for reporting of CRI, RI, PMI and CQI are assigned with specific priority value in UCI (CSI part 1 or CSI part 2). Depending on the number of bits allocated for UCI transmission, CSI reports, CSI sub-configurations, bitfields or groups of bitfields with higher / lower priority value can be dropped and not reported by the UE. In one or more embodiments of the present disclosure, bitfields corresponding to subband CSI (PMI / CQI) for even subbands and odd subbands corresponding to CRI li, CSI report r form two bitfield groups assigned with priority values pe(ir,r) and po(ir,r) respectively, i = {0,1,…,Lr-1}, r = {0,1,…,R-1}, where R is the number of CSI reports scheduled for transmission in UCI and / or total number of CSI sub-configurations across all reports scheduled for transmission in UCI. Bitfield groups for different CSI report, CSI sub-configurations, CRIs and subbands can be interlaced in different way. For example, the following equations can be used, where L Attorney Docket No.: AF9389-PCT (31517-3585) corresponds to the maximum number of selected CRIs across different CSI reports L = max(L1, L2, …, LR). - po(ir,r) = R·L·0 + R·ir + r and pe(ir,r) = R·L·1 + R·ir + r - po(ir,r) = 2·L·r + L·0 + irand pe(ir,r) = 2·L·r + L·1 + ir- po(ir,r) = R·L·0 + L·r + ir and pe(ir,r) = R·L·1 + L·r + ir - po(ir,r) = 2·R·ir+ R·0 + r and pe(ir,r) = 2·R·ir+ R·1 + r - po(ir,r) = 2·L·r + 2·ir + 0 and pe(ir,r) = 2·L·r + 2·ir + 1 - po(ir,r) = 2·R·ir+ 2·r + 0 and pe(ir,r) = 2·R·ir+ 2·r + 1 In another embodiment RI and / or wideband (WB) CQI values reported in CSI part 1 per each of L selected CSI-RS resource are used for ordering of PMI and / or subband (SB) CQI bitfields in CSI part 2 (figure 2). In one option f(RIs1, WB_CQIs1) ≥ f(RIs2, WB_CQIs2) ≥ f(RIs3, WB_CQIs3) ≥ … ≥ f(RIsS, WB_CQIsS), where f() is a function of RI and WB CQI values (e.g., channel capacity function), RIsi and WB_CQIsi correspond to RI and WB CQI reported for CSI-RS resource with index si. For example, f(RI, WB_CQI) = CQI_max·RI + WB_CQI or f(RI, WB_CQI) = RI_max·WB_CQI + RI ,where CQI_max is the maximum possible CQI value which can be reported by the UE, RI_max is the maximum possible RI value which can be reported by the UE. In case of f(RI, WB_CQI) = CQI_max·RI + WB_CQI, higher priority is given to CSI feedback with higher RI, and among CSI feedback with same RI, higher priority is given to CSI feedback with higher CQI value. In another example, f(RI, WB_CQI) may represent priority as a function of potential throughput or total spectral efficiency of the CSI feedback represents. The CQI are mapped to specific spectral efficiency (SE) (per layer), and SE could be multiple with RI to obtain the total spectral efficiency. The SE could be also obtained by multiplication of the modulation order (number of bits per modulated symbol) by code rate (CR). For example, f(RI, WB_CQI) = RI * SE, where SE is the spectral efficiency. In case two CSI feedback have identical priority value by f(RI, WB_CQI) then higher priority could be given by CSI feedback configuration ID and / or sub-configuration ID. In other embodiment L RI and / or wideband (WB) CQI values reported in CSI part 1 and F < L PMI and / or subband (SB) CQI bitfields are reported in CSI part 2, where F is fixed in the specification or configured via higher layers or selected by the UE. Further, the CSI-RS resources corresponding to reported PMI and SB CQI can be determined based on RI and / or wideband (WB) CQI values reported in CSI part 1. In one option, UE determines whether to drop PMI and SB CQI for a CRI s in the CSI part 2 based on RI and WB CQI value for CRI s (figure 3). For example, RI or CQI or f(RI, WB_CQI) is compared with a threshold Q, where Q is fixed in the specification, or configured Attorney Docket No.: AF9389-PCT (31517-3585) by higher layers, or determined based on RI and / or WB CQI for CRI values other than s. F is determined based on the actual number of reported CRI values. The above descriptions are for purposes of illustration and are not meant to be limiting. Numerous other examples, configurations, processes, algorithms, etc., may exist, some of which are described in greater detail below. Example embodiments will now be described with reference to the accompanying figures. FIG. 1 shows example reporting 100 of multiple CSI feedback for multiple CSI-RS resources corresponding to multiple CRI values, in accordance with one or more example embodiments of the present disclosure. Referring to FIG.1, a gNB 102 communicates with a UE 104. The gNB 102 transmits a CSI-RS 105 on a set of CSI-RS resources to the UE 104, the CSI-RS resources each corresponding to a different CSI-RS resource index. The UE 104 receives the CSI-RS 105 and performs a measurement 106 of the CSI-RS 105 resources, and computes CSI feedback corresponding to the CSI-RS 105 resources that correspond to the CRIs. The computed CSI feedback bits are reported in a CSI report 108 from the UE 104 to the gNB 102. The CSI report 108 may include multiple CRI feedback (e.g., CSI sub-reports 1-N) corresponding to respective CRI. S > 1 sub-configurations {s1,s2,…,sS} can be configured for a UE for a CSI report. A CSI sub-configuration can be configured by using higher layer information element CSI- ReportSubConfig. A CSI sub-configuration with index s may include a list of Ks CSI-RS resources. In one or more embodiments of the present disclosure, if UE selects a CSI-RS resource with index kAfor the CSI sub-configuration sA, UE shall not select the CSI-RS resource with index kA for a CSI sub-configuration other than sA. Further, the selected CSI-RS resources {k1,k2,…,kS} order may be decided by the UE (e.g., in increasing order of signal power or channel quality or channel capacity on the corresponding CSI-RS resources). Alternatively, UE shall report CSI for CSI-RS resources {k1,k2,…,kS} in ascending order of CRI (or descending order of CRI). In case UE report CSI for CSI-RS resource in ascending (or descending) order of CRI, it is assumed gNB configures the CSI-RS resources in the prioritization order for which the gNB requests to potentially receive CSI. FIG. 2 shows example reporting 200 of multiple CSI feedback corresponding to different CRI based on a DCI or MAC-CE transmission from a gNB, in accordance with one or more example embodiments of the present disclosure.

The CSI-RS 105 correspond to set of CSI-RS resources used by the UE 104 to perform a measurement 204 and computation of CSI feedback. The DCI or MAC-CE 202 corresponds to either DCI or MAC-CE that contains information on number of CSI feedback expected to be reported as part of multi-CRI CSI feedback. The UE 104 sends a report 206 (e.g., an SP- SCI or A-CSI report) that includes multiple CSI feedback corresponding to different CSI-RS resources (associated with different CRI). The CSI sub-reports 1-N refer to individual CSI feedback for different CSI-RS resources each corresponding to different CRI. FIG.3 shows example reporting of multiple CSI feedback for multiple CRIs in multiple CSI reporting instances, in accordance with one or more example embodiments of the present disclosure. Referring to FIG.3, the gNB 102 sends the CSI-RS 105 to the UE, and a DCI or MAC- CE 202. The CSI-RS 105 correspond to set of CSI-RS resources used by the UE 104 to perform a measurement 204 and computation of CSI feedback. The DCI or MAC-CE 202 corresponds to either DCI or MAC-CE that contains information on number of CSI feedback expected to be reported as part of multi-CRI CSI feedback. The DCI or MAC-CE 202 in FIG. 3 signals one CSI feedback report among all CSI-RS resources of a CSI-RS resource set, and the sends a report 302 (e.g., SP-CSI or A-CSI report) including one CSI feedback (e.g., CSI sub-report 1) for a specific CSI. The gNB 102 sends a DCI or MAC-CE 304 signals multiple CSI feedback report among CSI-RS resources of a CSI-RS resource set excluding the CSI-RS resource corresponding to CSI feedback reported in the DCI or MAC-CE 202. The UE 104 sends a report 306 (e.g., SP-CSI or A-CSI report) including multiple CSI feedback each with different CRI (e.g., CSI sub-reports 2-N).

The connection between the UE 702 and the AP 706 may be consistent with any IEEE 802.11 protocol, wherein the AP 706 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 702, RAN 704, and AP 706 may utilize cellular-WLAN aggregation (for example, LWA / LWIP). Cellular-WLAN aggregation may involve the UE 702 being configured by the RAN 704 to utilize both cellular radio resources and WLAN resources.

For example, the UE 702 and RAN 704 may use carrier aggregation to allow the UE 702 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first / second ANs may be any combination of eNB, gNB, ng-eNB, etc. The RAN 704 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and / or feLAA mechanisms based on CA technology with PCells / Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium / carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol. In V2X scenarios the UE 702 or AN 708 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications / software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular / WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network. In some embodiments, the RAN 704 may be an LTE RAN 710 with eNBs, for example, eNB 712. The LTE RAN 710 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI- RS for CSI acquisition and beam management; PDSCH / PDCCH DMRS for PDSCH / PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation / detection at the UE. The LTE air interface may operating on sub-6 GHz bands. Attorney Docket No.: AF9389-PCT (31517-3585) In some embodiments, the RAN 704 may be an NG-RAN 714 with gNBs, for example, gNB 716, or ng-eNBs, for example, ng-eNB 718. The gNB 716 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 716 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 718 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 716 and the ng-eNB 718 may connect with each other over an Xn interface. In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 714 and a UPF 748 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN714 and an AMF 744 (e.g., N2 interface). The NG-RAN 714 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH / PDCCH DMRS similar to the LTE air interface.

The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS / SSS / PBCH. In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 702 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 702, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 702 with different amount of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 702 and in some cases at the gNB 716. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
