Description

METHODS FOR CHANNEL MEASUREMENT AND REPORTING IN A NETWORK IN PRESENCE OF RESTRICTIONSFIELD OF THE INVENTION

[0001] The present disclosure, generally, relates to a method for measurement and reporting in a cellular system. More particularly, the present disclosure relates to a method for priority-based measurement and reporting in the cellular system.BACKGROUND OF THE INVENTION

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

[0003] In sub band full duplexing (SBFD) communication, a node can simultaneously perform downlink (DL) and uplink (UL) operation in different subbands within the same carrier frequency. A subband is a set of frequency resources within the carrier. The subbands for DL and UL operations can be of fully overlapping, partially overlapping or nonoverlapping. FIG. 1 illustrates various overlapping scenarios. The (a) of FIG. 1 depicts an example of non-overlapping subbands, the (b) of FIG. 1 depicts an example of a partial overlapping subbands, and (c) of FIG. 1 depicts an example of a fully overlapping subbands.

[0004] One of the major drawbacks of the SBFD operation is self-interference (SI) created by simultaneous transmission and reception in a node. In case of SBFD with nonoverlapping subbands, the guard bands can be used between the DL and UL subbands to minimize the impact of SI, whereas in case of partial and fully overlapping subbands additional interference cancellation mechanisms are needed to handle SI.

[0005] The fifth-generation new radio (5G-NR) technology is designed as Time Division Duplexing (TDD), where a carrier can be configured for either DL or UL operations at a time. In SBFD, subbands can be configured within the carrier and different set of operation can be configured within the subband (E.g., the UL subband can be configured within a DL carrier). Further, the SBFD operation can be enabled for a set of time resources, referred as SBFD active time resources throughout the disclosure, in which the subband is active. The SBFD active time resource can be contiguous or non-contiguous. The time resource granularity can be at symbol level, at slot level or resource type within a slot.

[0006] FIG. 2 illustrates a notion of subband and SBFD active time resource. FIG. 2 shows a resource grid, consisting of 8 resource blocks (RBs) within a carrier, configured for DL operation using conventional methods. The RBs i.e. RBI to RB4 is configured as UL subband and it is active from symbol 1 to symbol 5. Hence, in symbol 1 to 5, a BS can simultaneously transmit DL to a user equipment (UE) using RB0, RB5, RB6, and RB7, and can receive the UL from another UE in RB 1 to RB4.

[0007] In the cellular network, the BS may operate with multiple carriers, each with large bandwidth, whereas the UE may not have access to all the carriers or to entire bandwidth of a carrier. The set of frequency resources for which the UE have access within a carrier is known as bandwidth part (BWP). The UE can be configured with multiple BWPs of which a subset can be active at a time. Further, separate BWP can be configured for DL and UL operations. In case a BWP of UE overlaps with subband for SBFD operation, then the size of the BWP can vary in SBFD active time resource depending on the overlap with SBFD subband.

[0008] FIG. 3 illustrates an example scenario depicting a conflict among the SBFD operation and conventional configurations. As shown in FIG. 3, the UE is configured with a DL BWP from RB3 to RB5 and the UL subband for SBFD operation is defined from RB 1 to RB4. Therefore, there is partial overlap (RB3 and RB4 are common) between DL BWP of UE and UL subband for SBFD operation. In SBFD active time resources (symbol 1 to 5 in FIG. 3), the BS performs UL operation using UL subband. Hence, the UE will not receive any DL signal in DL BWP overlapping with UL subband (i.e., in RB3 and RB4). Therefore,in Fig. 3, the DL BWP of UE consist of RB5 alone in symbol 1 to 5, where SBFD is active, whereas the DL BWP of the UE consist of RB3 to RB5 in symbol 0, symbol, 6 and symbol 7.

[0009] Enabling SBFD operation in the cellular network can create several conflicts in the system. Also, it can create unnecessary transmission / monitoring at the nodes in the network. E.g., in Fig. 3, the UE may be configured to receive signals in RB3-RB5 in symbol 3, hence the UE expect DL signals and keep monitoring the scheduled resources to receive DL signal. However, the BS, in SBFD mode, is not performing DL operation in RB3 and RB4 in symbol 3. Further, enabling SBFD creates additional interference in the network and impacts various measurements. For example, in FIG. 3, the BS performs simultaneous DL transmission and UL reception in symbols 1 to 5, creating SI at the BS. Further, in the network, the UE is receiving DL from the BS, and another UE is simultaneously transmitting UL to the BS in an SBFD symbol. Therefore, the UL transmission from the UE interfere with DL reception, creating UE-to-UE interference. The UE measures various channel and interference parameters in certain time and frequency resources and report it to the BS. The measurement is assumed to be valid for certain time duration and parameters for communication (e.g., modulation and coding scheme) in the time duration is determined by the BS based on the measurement report. However, the additional interference created by SBFD causes variation in channel and interference measurements. For example, the interference increases in SBFD active time resource resulting in reduction in signal to interference-noise ratio which in turn vary the channel quality ( For example, a Channel quality indicator (CQI)) reported by the UE and the MCS calculation). Therefore, separate measurement of channel and interference parameters is needed for SBFD active and SBFD inactive time resources. Further, the UE perform measurements using reference signal which span across a set of time and frequency resources. In an SBFD active time resources, the number of time, and frequency resources for measurement decreases resulting in reduction in accuracy of measurement. E.g., in the NR, the channel and interference measurements are performed using channel state information reference signal (CSLRS), which span across the whole BWP of the UE. In an SBFD active time resource, the BWP of the UE overlapping with SBFD subband become inactive and the UE does not receive any CSLRS resource in the inactive portion. In Fig. 3, the UE receive CSLRS in all RB3-RB5 in symbol 6, whereas the UE receive CSI-RS only in RB5 in symbol 3 to 5. Hence, accuracy of measured parameter varies in symbol 6 and symbol 3-5.

[0010] Similarly, in the cellular technologies, a large bandwidth (BW) is needed to support a variety of services and satisfy the increasing demand of data rates. However, the use of larger BW increases the power consumption at the BS, thereby increasing the operational cost of the network. Therefore, flexible adaptation of the channel BW is required to provide energy saving at the BS. For example, the BS can turn off transmission / reception in certain frequency range (otherwise subband) to reduce energy consumption. The BW can be adapted based on many parameters. For example, network load, user equipment (UE) uplink-downlink (UE-DE) traffic, etc. However, the adaptation of bandwidth creates issues similar to SBFD mentioned above. For e.g., the UE can be semi-statically configured by the BS for periodic receptions within certain frequency resources. Adapting the BW dynamically by the BS can cause deactivation of certain portion of the frequency resources configured to the UE, that leads to unnecessary monitoring by the UE. Further, The UE transmits CSI report in uplink control channel or UL data channel, along with feedback for a downlink signal, request for UL scheduling, information for power control etc. In case of separate measurement and reporting of parameters for SBFD and non-SBFD time resources such as symbols, the UE requires more resources to transmit the information of SBFD and non-SBFD symbols. If the resources allocated in a UL occasion are not enough to transmit the information, then the UE has to drop some of the information. Certain rules and priorities should be defined for dropping the UL signals / information in case of enabling SBFD operation in the cellular network. For example, the UE can group the parameters of SBFD and non-SBFD symbols into different groups and the groups can be dropped as per a priority order, indicated by BS or pre-configured. Moreover, the CSI measurement and reporting requires processing and computation in the UE. The UE needs to have enough capability to receive CSLRS resources, process them and report the CSI report, example, they need to have enough CSI processing unit (CPU) and memory to receive CSLRS resources, compute CSI parameters corresponding to a CSI report configuration and report the parameters. Further, the requirement increases in case the UE is configured with multiple CSI reports and / or report for separate parameters for SBFD and non-SBFD scenario. The CPU is occupied for certain OFDM symbols depending on report quantity, the number of CSLRS resources configured under CSLReportConfig, type of CSLRS resource, CSI report type,etc. In the case of UE reporting separate parameters for SBFD and non-SBFD scenario in same or different report based on the CSI-RS resources received in SBFD and non-SBFD symbols, the computation of CPU occupancy timeis impacted, hence certain methods should be defined for computing CPU occupancy time in case of enabling SBFD operation in the cellular network. The CSI-RS resources need to be received at the UE for the CSI measurement and reporting. The UE needs to have enough capability to receive the CSI-RS resources and the associated ports for the measurements. The maximum number active CSI- RS ports or active CSI-RS resources which can be supported at the UE are reported as UE capability by the UE to the BS. For example, per component carrier capabilities on simultaneous active CSI-RS resources and simultaneous active CSI-RS ports for UEs operating in the field is reported as maxNumberSimultaneousNZP-CSI-RS-PerCC = 4 and totalNumberPortsSimultaneousNZP-CSI-RS-PerCC = 32. Further, if a UE is configured with one or more CSI Reporting Settings, where a CSI-RS resource is referred N times by the report settings, the CSI-RS resource and the CSI-RS ports within the CSI-RS resource are counted N times. The requirement of active CSI-RS resources and active CSI-RS ports increases in case the UE is configured to report separate CSI parameters for SBFD and non- SBFD scenarios. For example, the UE is configured with a report configuration comprising two subconfigurations, for SBFD and non-SBFD symbol types, where each sub configuration is associated with one CSI-RS resource. In this example, the UE receives one CSI-RS resource for channel measurement for both SBFD symbols and non-SBFD symbols. The total number of active CSI-RS resources and total number of active CSI-RS ports corresponding to both SBFD and non-SBFD increases, thereby impacting number of active CSI-RS resources.

[0011] Therefore, there is a need to define a new methodology for reducing the impact of the SBFD and adaptation of the bandwidth on the channel measurement and reporting framework in the cellular network particularly for CSI reporting and dropping, computing CPU processing time, and handling and utilizing UE capabilities.OBJECTS OF THE INVENTION

Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.

[0007] Exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. This disclosure may however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those of ordinary skill in the art. Moreover, all statements herein reciting embodiments of the disclosure, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future (i.e., any elements developed that perform the same function, regardless of structure).

[0008] According to an embodiment, the present disclosure discloses a method for Channel State Information (CSI) measurements for a network enabled with sub-band full duplexing (SBFD). In particular, the present disclosure provides a method of prioritization in reporting of parameters, in case a separate measurement and reporting of parameters for SBFD and non-SBFD time resources such as symbols are required. In an embodiment, the UE can group the parameters of SBFD and non-SBFD symbols into different groups and the groups can be dropped as per priority order, indicated by BS or pre-configured.

[0009] In general, the channel between transmitter and receiver is an important entity in determining various parameters for transmission (e.g., transmit power, the MCS, etc.) in wireless communication system. In 5G-NR, the UE is configured to measure and report various parameters of the channel using CSI-RS. The UE is configured with CSI-report configurations where each configuration indicates to the UE the parameters to measure, method to compute the parameters, the resources to send the report, etc. Further, each CSI- report configuration is associated with one or more CSI-RS resource sets, where each resource set comprises one or more CSI-RS resources. The UE receives the CSI-RS resources associated with the CSI-Report and compute the parameter of the channel, indicated by the CSI-RS report configuration, using the received resources and report the parameter to the BS. The following paragraphs briefly describes the CSI measurement and reporting framework in 5G-NR and how the parameters associated with CSI measurement and reporting are configured to the UE.CSI Resource Configuration:

[0010] The UE can be configured with one or more groups of CSI-RS resource sets using the information element (IE) CSI-ResourceConfig in radio resource control (RRC) message. The IE defines a group and indicates an identity of the CSI-RS resource sets included in the group. The group comprises either CSI-RS resource sets for channel measurement or CSI-RS resource sets for interference measurement. CSI-ResourceConfig also specifies the time domain behavior of CSI-RS resource set within the group. The time domain behavior of the CSI-RS resource set indicates whether the CSI-RS resources within the CSI-RS resource set is periodic, semi-persistent or aperiodic. In the case of periodic, the CSI-RS resources within the CSI-RS resource set are transmitted to UE at regular intervals. Further, the reception of periodic CSI-RS resources starts immediately after the configuration. In case of semi-persistent, the CSI-RS resources within the CSI-RS resource set are transmitted periodically after a trigger event. UE first receives a trigger from BS, semi- statically using MAC-CE, followed by CSI-RS resources at regular intervals. The aperiodic the CSI-RS resources within the CSI-RS resource set are transmitted, only once based on scheduling, after a dynamic trigger. Therefore, the UE receives dynamic trigger followed by aperiodic CSI-RS transmission.

[0011] The details of the CSI-RS resource set for channel measurement are provided to the UE using IE NZP-CSI-RS-ResourceSet IE in RRC message, which indicate identity of the CSI-RS -Resources forming the Set, the offset between trigger and transmission of resources, information about the antenna elements (or antenna ports used for transmission of CSI-RS -Resources within the set, etc. The details of the CSI-RS resource sets for interference measurement are provided to the UE by IE CSI-IM-ResourceSet, which indicates the identity of the CSI-RS resource for interference measurement (CSI-IM) forming the set. The NZP-CSI-RS-Resource IE in RRC is used to configure CSI-Resources for channel measurement to the UE. The IE indicates identity of the configured CSI- Resource, the mapping of CSI-Resource within a resource block, power control parameters, TCI state information, periodicity and offset, etc.

[0012] The UE performs CSI measurements across its BWP. Each CSI-RS resource, configured to the UE, occupies certain resource elements (REs) and OFDM symbols in a resource block. The UE assumes the same mapping pattern across all RBs within its BWP depending on the density of the CSI-RS. If the density is one, the mapping pattern is repeated across all RBs in the BWP. If the density is half, then alternate RBs contain CSI-RS and follow the same mapping pattern. Hence, each CSI-RS resource spans across whole BWP of UE and the UE performs CSI measurements using the CSI-RS resource received across its BWP.CSI Report Configuration

[0013] The UE is configured to transmit CSI report using the IE CSI-ReportConfig in RRC message. The UE can be configured to transmit CSI report periodically, semi-persistent manner based on trigger or aperiodically. The configuration is done by the element reportConfigType in CSI-ReportConfig, which can be set to 'aperiodic', 'semiPersistentOnPUCCH', 'semiPersistentOnPUSCH', or 'periodic'. The entity reportConfigType further indicates whether the CSI report is to be transmitted in UL control channel or UL data channel and the scheduling of the control / data channel. The periodic CSI report is always transmitted in UL control channel. The semi-persistent report can be transmitted in UL control channel based on MAC-CE trigger or in UL data channel based on dynamic trigger depending on the configuration. The aperiodic CSI report is always transmitted in UL data channel.

[0014] The CSI-ReportConfig configures the resources for transmitting the CSI report. For 'periodic' and 'semiPersistentOnPUCCH' / 'semiPersistentOnPUSCH' CSI reporting, the configured periodicity and slot offset applies in the numerology of the UL BWP in which the CSI report is configured to be transmitted on. For periodic and semi-persistent CSI reporting, the periodicity and slot offset are configured using the element reportSlotConfig. The UE can determine the frame number and slot number within the frame to transmit CSI report based on periodicity and slot offset indication in reportSlotConfig and a mapping rule defined in NR specification. Separate mapping rule is defined for semi-persistent reporting on PUCCH and PUSCH. For semipersistent CSI reporting on PUSCH and aperiodic CSI reporting the possible set of slot offsets are configured using the element reportSlotOffsetList in CSI-ReportConfig and the triggering DCI down selects one value from the set.CSI Resources for Measurement

[0015] The CSI-ReportConfig indicates the CSI-RS resources in which the UE has to measure the CSI parameters. The indication is using CSI-ResourceConfigID, which selects one or more groups of CSI-RS resource sets configured to the UE using CSI- ResourceConfig. Further, the indication is separate for CSI-RS resources for channel measurement and CSI-RS resources for interference measurement. E.g., the group of CSI- RS Resource sets selected by one CSI-ResourceConfigID contain only CSI-RS resources for channel measurement. Similarly, the group corresponding to CSI-ResourceConfigID, indicated by CSI-ReportConfig, contains only CSI-RS resources for interference measurement.CSI Report Quantity

[0016] The CSI-ReportConfig configures the CSI parameters to report and assisting information for calculating the parameter value. The element reportQuantity in CSI- ReportConfig can indicate UE to report either 'none', 'cri-RI-PMI-CQI ', 'cri-RI-il', 'cri-RI- il-CQI', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR', 'cri-RI- LI-PMI-CQI', 'cri-RSRP- Index', 'ssb-Index-RSRP- Index', 'cri-SINR- Index' or 'ssb-Index- SINR- Index'. The assisting information for calculating the CSI parameter comprises indexof the CQI table, from the set of tables defined in NR specification, to be used for calculation of CQI, the codebook configuration for calculation of Precoding Matrix Indicator (PMI), ports to be used for measurement of CQI, etc.Wideband and Subband CSI Reporting

[0017] CSI-ReportConfig also configures whether the UE has to measure the parameter for whole BWP or subband within the BWP. A CSI-ReportConfig configures for wideband reporting if• reportQuantity is set to 'cri-RI-PMI-CQI', or 'cri-RI-LI-PMI-CQI', cqi- Formatlndicator is set to 'widebandCQI' and pmi-Formatlndicator is set to 'widebandPMI', or• reportQuantity is set to 'cri-RI-PMI-CQI', codebookType is set to 'typell- PortSelection-rl7' with M=1 and cqiFormatlndicator is set to 'widebandCQI', or• reportQuantity is set to 'cri-RI-il' or• reportQuantity is set to 'cri-RI-CQI' or 'cri-RI-il -CQI' and cqi-Formatlndicator is set to 'widebandCQI', or• reportQuantity is set to 'cri-RSRP' or 'ssb-Index-RSRP' or 'cri-SINR', or 'ssb-Index- SINR' or 'cri-RSRP-Index' or 'ssb-Index-RSRP-Index' or 'cri-SINR-Index', or 'ssb- Index-SINR-Index’Otherwise, the UE is configured to report in subband frequency-granularity. In the case of configuring subband reporting, CSI-ReportConfig further indicates the parameters to be reported in subband basis, size of subband, number of subbands within the BWP etc. If element cqi-Formatlndicator in CSI-ReportConfig is configured as wideband then the UE reports single wideband CQI for the entire CSI reporting band. If cqi-Formatlndicator in CSI-ReportConfig is configured as subband then, UE reports CQI per subband. Similarly, the UE reports wideband or subband PMI depending on the element pmi-Formatlndicator. In the case of subband reporting, the element csi-ReportingBand in CSI-ReportConfig Indicates whether the subbands are contiguous or non-contiguous in the bandwidth part which CSI shall be reported for. The element csi-ReportingBand indicates a bit string where each bit in the bit-string represents one subband. The right-most bit in the bit string represents the lowest subband in the BWP. The bandwidth of the subband is determined bythe UE based number of PRBs in the BWP and element subbandSize in CSI-ReportConfig. A table is defined in NR specification, illustrated in Table 1 below, relating the number of PRBs in BWP of UE and possible values for subband size. UE select one row from Table 1 or possible values for subband size based on the size of BWP. Further, the element subbandSize in CSI-ReportConfig indicates whether to use value 1 or value2 from the selected row.Table 1: Configured sub-band sizes and mapping to BWP sizeCSI Reference Resource and Time Restriction for CSI Measurement

[0018] After receiving the CSI-RS resources, the UE requires time to process the CSI- RS resource, compute the CSI parameters and prepare the report. Hence there should be a time gap between the CSI resource measurement and sending CSI report. For transmitting a CSI report in a time instant, the UE will consider only the CSI-RS resources received before certain duration from the CSI reporting time and that time duration is characterized by CSI reference resource. Therefore, CSI reference resource is defined as the minimum time duration, from the CSI reporting time, before which a CSI-RS resource need to be received at the UE so that the UE measure CSI parameters based on the CSI-RS resource and include it in the CSI report. E.g., if CSI reference resource is configured as 4 slots and the UE is configured to report CSI in slot n, then the UE measures the configured CSI parameters using the CSI-RS resources received no later than slot n-4. Further, the UE reports CSI Report only if it receives at least one configured CSI-RS resource before the CSI Reference resource. After the CSI report (re)configuration, serving cell activation, BWP change, or activation of SP-CSI, the UE reports a CSI report only after receiving at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IMoccasion for interference measurement no later than CSI reference resource and drops the report otherwise.

[0019] In the case of CSI reporting, the UE measures a CSI resource in multiple time instances, evaluates the CSI parameters for multiple time instances and averages them to obtain the value of the parameter for reporting. The time restriction for measurement is configured to the UE to avoid averaging of the parameters based on multiple CSI resources. E.g., if time restriction is configured to the UE, then the UE determines CSI parameter based on the latest CSI-RS resource received before CSI reference resource. The CSI- ReportConfig can configure elements timeRestrictionForChannelMeasurements and timeRestrictionForlnterferenceMeasurements to enable time domain restriction for channel measurements and interference measurement, respectively. The following behaviors are defined in NR specification:• If the higher layer parameter timeRestrictionForChannelMeasurements is set to "notConfigured", the UE shall derive the channel measurements for computing CSI value reported in uplink slot n based on only the CSI-RS resources for channel measurement, no later than the CSI reference resource, associated with the CSI resource setting.• If the higher layer parameter timeRestrictionForChannelMeasurements in CSI- ReportConfig is set to "Configured", the UE shall derive the channel measurements for computing CSI reported in uplink slot n based on only the most recent, no later than the CSI reference resource, occasion of CSI-RS resources for channel measurement.• If the higher layer parameter timeRestrictionForlnterferenceMeasurements is set to "notConfigured", the UE shall derive the interference measurements for computing CSI value reported in uplink slot n based on only the CSI-RS resource for interference measurement no later than the CSI reference resource associated with the CSI resource setting.• If the higher layer parameter timeRestrictionForlnterferenceMeasurements in CSI- ReportConfig is set to "Configured", the UE shall derive the interference measurements for computing the CSI value reported in uplink slot n based on themost recent, no later than the CSI reference resource, occasion of CSI-RS resource for interference measurement associated with the CSI resource setting.Impact of SBFD on CSI Omission and Dropping Rules

[0020] The UE transmits CSI report in uplink control channel or UL data channel, along with feedback for a downlink signal, request for UL scheduling, information for power control etc. If the resources allocated in a UL occasion are not enough to transmit the information, then the UE has to drop some of the information. Certain rules and priorities are defined in NR for dropping the UL signals / information. E.g., the UE maps CSI report in the scheduled UL resources and then punctures the resources to incorporate the feedback information, in case of lack of UL resources to accommodate CSI report and feedback. Further, the CSI report, corresponding to each CSLReportConfig, may comprises two parts: Part 1 contains parameters such as CSLRS Resource Indicator (CRI), Rank indicator (RI) and CQI, Part2 comprises other parameters corresponding to wideband reporting (e.g., PMI and Layer indicator (LI)), parameters for even subband and parameters for odd subband. In case of lack of UL resources, Part 1 of CSI report is given higher priority compared to Part 2. Further, within part 2, parameters for wide band are given priority followed by parameters for even subband and odd subband. The following dropping rule is applied:• UE first drops part 2 CSI corresponding to each CSLReportConfig with priority order WB>ESB>OSB.• UE drops part 1 CSI corresponding to each CSLReportConfig once all part 2 are dropped.E.g., in the case of UE configured with two CSLReportConfig, the priority order is given in Table. 2 below.- ►Decreasing order of priorityTable 2

[0030] In sub band full duplexing (SBFD) communication, a node can simultaneously perform downlink (DL) and uplink (UL) operation in different subbands within the same carrier frequency. The subbands for SBFD operation can overlap with the bandwidth part configured to the UE. Therefore, the size of the active BWP configured to the UE will vary depending on whether the BWP overlaps with subband configured for SBFD operation, whether SBFD is active in a time resource and whether the transmission / reception direction of the subband is aligned with the transmission / reception direction of BWP. Further, a UE performs channel / interference measurement and reporting using the channel state information reference signal (CSI-RS), which span across the entire BWP of the UE. The variation in size of BWP causes deactivation of some of the CSI-RS resources which impacts the measurement accuracy of various channel parameters. Hence, a separate reporting of parameters of the channel is needed for SBFD active and SBFD inactive resources. The separate measurement and reporting of channel parameters for SBFD active and SBFD inactive resources causes increment in processing and computation at the UE and creates lack of UL resource for CSI reporting. In case of lack of UL resources for reporting CSI parameters, priorities and dropping rules need to be defined among the parameters reported for SBFD and non-SBFD resources. The present disclosure describes the impact of enabling SBFD operation on CSI omission and dropping rules. Further, the invention describes the impact of SBFD on computational and processing capabilities of the UE and discloses methods to overcome the impacts.

[0031] According to an embodiment, in case of separate measurement and reporting of parameters for SBFD and non-SBFD time resources such as symbols, the UE can group the parameters of SBFD and non-SBFD symbols into different groups and the groups can be dropped as per priority order, indicated by BS or pre-configured. The following options can be considered for defining priority and dropping.

[0032] According to an embodiment, in one option, the UE can divide the CSI reports into two groups, where the first group comprises Part 1 information for SBFD and non- SBFD symbols and the second group consists of Part 2 information of SBFD and non-SBFD symbols. Here the definition / content of Part 1 and Part 2 are the same as in NR. In case of lack of UL resources, the UE drops Part 2 CSI corresponding to each CSLReportConfig followed by Part 1.a. Following options is considered for defining priority for the measurements corresponding to non-SBFD and SBFD symbols within a CSI-ReportConfig i. In one method, within each group in a CSI-ReportConfig, the measurements from non-SBFD symbols are given priority over SBFD symbols. E.g., in the case of UE configured with 2 subconfigurations within a CSI-ReportConfig for CSI measurements on SBFD and non-SBFD symbols, the priority order within a CSI- ReportConfig is given in Table 3. The Part 1 measurements from non-SBFD are prioritized over part 1 measurements from SBFD. Similarly, priority of part 2 wideband measurements from non-SBFD is prioritized over part 2 wideband measurements from SBFD. In case of lack of UL resources, UE drops the measurements in decreasing order of priority, i.e., drops priority 8 followed by priority 7, priority 6, etc. ii. In an alternate approach, within each group in a CSI-ReportConfig, the measurements from SBFD symbols are given priority over non-SBFD symbols. E.g., in case of UE configured with 2 subconfigurations within a CSI-ReportConfig, the Part 1 measurements from SBFD is prioritized over part 1 measurements from non- SBFD.Table 3- Within a group in a CSI-ReportConfig measurement from non-SBFD symbol is given priority over SBFD.

[0033] According to an embodiment, in another method, the measurements from non-SBFD symbols are given priority over SBFD symbols in a CSI-ReportConfig. E.g., in the case of UE configured with 2 subconfigurations for CSI measurements on SBFD and non-SBFD symbols within a CSI-ReportConfig, the Part 1 and Part2 measurements from non-SBFD symbols is prioritized over parti and part 2 measurements from SBFD. The priority order within a CSI-ReportConfig is given in Table 4. In case of lack of UL resources, UE dropsthe measurements in decreasing order of priority, i.e., drops priority 8 followed by priority 7, priority 6, etc.

[0034] In an alternate approach, the measurements from SBFD symbols are given priority over non-SBFD symbols in a CSI-ReportConfig. E.g., in case of UE configured with 2 subconfigurations within a CSI-ReportConfig, the Part 1 and Part2 measurements from SBFD symbols is prioritized over parti and part 2 measurements from non-SBFD.Table 4- Within a CSI-ReportConfig, measurements from non-SBFD symbols is given priority over SBFD.

[0035] According to an embodiment, in another method, the UE groups the parameters together and assigns equal priority. In case of lack of UL resources, the UE drops the entire group together. E.g., parameters measured from odd and even subbands can be grouped and can be given equal priority, as illustrated in Table 5. In the CSI report the UE includes the measurements from ESB followed by OSB. In case of lack of UL resources, drop the measurements from ESB and OSB together. Another e.g., is illustrated in Table 6, where the measurements in Part 2 form a group and all measurements in Part 2 are given equal priority. The UE includes Part 2 WB measurements followed by Part 2 even SB and part 2 odd SB in the report. In case of lack of UL resources, UE drops the entire Part 2 measurements together. In a yet another example, as illustrated in Table 7, where the measurements in Part 1 form a group and all measurements in Part 1 for both SBFD and non-SBFD symbols are given equal and highest priority, similarly the wideband measurements in Part 2 form a second group and all wideband measurements in Part 2 are given equal priority and the measurements in all even and all odd subbands for both the SBFD and non-SBFD symbols forms a third group are given equal priority.Table 5- Measurements in even and odd subbands are given equal priority within a CSI- ReportConfig.Table 6- Assigning equal priority for measurements in Part 2 CSI report.Table 7- Grouping of measurements with equal priority within a CSI-ReportConfig.

[0036] According to an embodiment, for defining the priority for CSI measurements across the CSI-ReportConfig, following methods are used: i. In one method, equal priority is assigned for all CSI-ReportConfig. Hence, the parameter with same priority is arranged based on ascending order of CSI- ReportConfig ID as illustrated in Table 8. In case of lack of UL resources, the UE drop the measurements with equal priority in all CSI-Report-config. E.g., in Table 8, UE first drops Priority 4 measurements from CSI- ReportConfig 1 and CSI-ReportConfig2 in case of lack of UL resources, followed by Priority 3 measurements, Priority 2 measurements, etc. ii. In another method, the priority is defined for CSI-ReportConfig. E.g., the CSI- ReportConfig is assigned priority based on CSI-ReportConfig ID, i.e., CSI- ReportConfig with lowest ID is given highest priority. In case of lack of UL resources, the UE drop measurements with lowest priority in a low priority CSI-ReportConfig. In particular, drop the measurements of high index CSLreport config which is of low priority then starts dropping of measurements of low index report config which is of high priority E.g., in Table 8, Priority 4 measurements of CSLReportConfig2 is dropped first, followed by Priority 4 measurements of CSI-ReportConfig 1, Priority 3measurements of CSI-ReportConfig2, Priority 3 measurements of CSI-ReportConfigl, etc.Table 8 - Arranging CSI measurements from different CSI-ReportConfig.

[0037] FIG. 4 illustrates a method 400 for assigning priority to the CSI parameters, the first group and the second group and transmitting the same based on the priority by at least one node, according to an embodiment of the present disclosure. In an embodiment, the at least one node is one of a user equipment (UE), relay, IAB-MT, IAB-DU, BS, and repeater. Further, explanation is provided with respect to the UE while communicating with a BS, however, the method can be performed by the relay, Non-Terrestrial Network (NTN), Integrated access and backhaul-Mobile Termination (IAB-MT), Integrated access and backhaul-Distributed Units (IAB-DU), BS, and repeater.

[0038] According to an embodiment the UE, at step 401, receives at least one first configuration of SBFD from a base station (BS). Further, at step 403, the UE receives at least one second configuration for CSI reporting from the BS. Further, at step 405, the UE measures the at least one CSI parameter for SBFD and at least one CSI parameter for non sub-band full duplexing (NSBFD). As an example, the at least one CSI parameter comprises at least one of: Channel Quality Indicator (CQI), Channel Rank Indicator (CRI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Precoding Matrix Indicator (PMI), Layer indicator (LI), Rank Indicator (RI) and Signal-to-Interference-plus-Noise Ratio (SINR). Further, at step 407, the UE forms a plurality of groups using the at least one CSI parameter for the SBFD and the NSBFD symbols. Further, as explained above, at step 409, the UE assigns priorities to the plurality of groups and priorities to at least one CSI parameter of each group from the plurality of groups. Further, at step 411, the UE transmits at least one of at least one group from the plurality of groups and the at least one CSI parameter of the at least one group in at least one CSI report based on the priorities.

[0039] According to an embodiment, to transmit the at least one group as disclosed the step 411, the UE determines the uplink (UL) resources for sending the at least one CSI report. Further, the UE drops the at least one of the groups and the at least one CSI parameter of the at least one remaining group from the at least one CSI report based on the priorities, when the uplink (UL) resources for sending at least one CSI report are not sufficient. Accordingly, the UE transmits the remaining groups of the plurality of groups and the at least one remaining CSI parameters of the remaining groups in at least one CSI report.

[0040] In an embodiment, to form a group at step 407, the UE at first divides the at least one CSI parameter into at least one set consisting of at least one CSI parameter where the at least one set of at least one CSI parameter comprises at least one of the part 1 CSI measurements, and the part 2 CSI measurements. In an embodiment, the Part 1 CSI measurements include CSLRS Resource Indicator (CRI), Rank Indicator (RI), and Channel Quality Indicator (CQI) and Part 2 CSI measurements include at least one CSI parameter for wideband (WB), Even Sub-Band (ESB), and Odd Sub-Band (OSB)), where with at least one CSI parameter for WB including Precoding Matrix Indicator (PMI) and Layer Indicator (LI). According to an embodiment, a group with part 1 CSI measurements has the priority higher than the group with part 2 CSI measurements. Further, the groups with at least one CSI parameter of NSBFD symbols have higher priority than the groups with the at least one CSI parameter of SBFD symbols.

[0041] In an embodiment, the priorities are assigned with at least one CSI parameter associated with the WB followed by at least one CSI parameter associated with the ESB, followed by at least one CSI parameter associated with the OSB. Further, the priories are assigned with at least one CSI parameter associated with Part 1 CSI measurements of NSBFD symbols followed by at least one CSI parameter associated with Part 1 CSI measurements of SBFD symbols, followed by at least one CSI parameter associated with Part 2 WB measurements of NSBFD symbols followed by at least one CSI parameter associated with Part 2 WB measurements of SBFD symbols, followed by at least one CSI parameter associated with ESB of NSBFD symbols, followed by at least one CSI parameter associated with ESB of SBFD symbols, followed by at least one CSI parameter associated with OSB of NSBFD symbols, followed by at least one CSI parameter associated with OSB of SBFD symbols.

[0042] In an embodiment, the UE assigns the priorities as at least one CSI parameter associated with Part 1 CSI measurements of SBFD symbols; followed by at least one CSI parameter associated with Part 1 CSI measurements of NSBFD symbols followed by at least one CSI parameter associated with Part 2 WB measurements of SBFD symbols, followed by at least one CSI parameter associated with Part 2 WB measurements of NSBFD symbols followed by at least one CSI parameter associated with ESB of SBFD symbols, followed by at least one CSI parameter associated with ESB of NSBFD symbols, followed by at least one CSI parameter associated with OSB of SBFD symbols, followed by at least one CSI parameter associated with OSB of NSBFD symbols. According to some embodiment, the UE assigns the priorities with at least one CSI parameter associated with Part 1 CSI measurements of NSBFD symbols followed by at least one CSI parameter associated with part 2 WB measurements of NSBFD symbols, followed by at least one CSI parameter associated with ESB of NSBFD symbols, followed by at least one CSI parameter associated with OSB of NSBFD symbols, followed by at least one CSI parameter associated with part 1 CSI measurements of SBFD symbols, followed by at least one CSI parameter associated with part 2 WB measurements of SBFD symbols, followed by at least one CSI parameter associated with ESB of SBFD symbols, followed by at least one CSI parameter associated with OSB of SBFD symbols. According to an embodiment, the UE assigns the groups with at least one CSI parameter of SBFD symbols with higher priority than the groups with at least one CSI parameter of NSBFD symbols.

[0043] According to some embodiment, the UE forms the one or more groups that comprises separate at least one CSI parameter. Further, the UE assigns equal priority to the at least one CSI parameter in a group. Further, the UE drops an entire group based on a priority order when the UE resources are not sufficient. In an embodiment, the at least one CSI report is transmitted according to the priority configured for the at least one CSI report.

[0044] According to some embodiment, the UE assigns the priority by arranging at least one CSI report corresponding to the at least one second configuration in one of an ascending order and a descending order of the indices of the at least one second configuration, where the indices are configured by an RRC parameter CSI-ReportConfigID, and assigns the order of priority to the CSI report in one of the ascending order and the descending order.

[0045] According to some embodiment, the UE transmits the at least one group by dropping the at least one group and the at least one CSI parameter in one of the ascending order and descending order of the assigned priorities, when the UL resources are not sufficient.

[0046] According to some embodiment, the UE drops all the at least one CSI parameter for both SBFD and NSBFD symbols when the UL resources are not sufficient to transmit all the at least one CSI parameter.

[0047] According to some embodiment, the at least one CSI parameter is reported separately in at least one CSI report for SBFD and in at least one CSI report for NSBFD symbols.

[0048] According to some embodiment, the UE forms the groups by grouping measurements for wideband (WB) in first group with highest priority. Further, grouping measurements for even subband (ESB) in a second group with the priority less than that of the first group, and grouping measurements for odd subband (OSB) in a third group with lowest priority.

[0049] According to some embodiment, the UE assigns priorities based on a predefined priorities or priorities signalled by the BS. In an embodiment, the BS performs the signalling through at least one of RRC, MAC-CE, and DCI.

[0050] According to some embodiments, UE assigns equal priority to groups comprising at least one CSI parameter for at least one subband (SB). Further, the UE drops all groups with at least one CSI parameter for at least one SB when the UL resources are not sufficient to transmit all the at least one CSI parameter for the at least one SB.

[0051] According to some embodiment, the UE forms the group by grouping all Part 1 measurements across both SBFD and NSBFD symbols in a first group with highest priority. Further, the UE forms the group by grouping WB measurements of Part 2 in second group, with lower priority than the first group with Part 1 measurements. Furthermore, the UEforms the group by grouping only at least one SB measurements in a third group with the lowest priority.

[0052] According to some embodiment, the UE transmits groups with at least one CSI parameter in a pre-determined order in the at least one CSI report.

[0053] According to some embodiment, the UE assigns the priorities by Part 1 measurements of NSBFD symbols, followed by at least one CSI parameter associated with part 1 measurements of SBFD symbols, followed by at least one CSI parameter associated with Part 2 measurements for at least one of NSBFD and SBFD symbols. The forthcoming paragraphs will explain the method 400 when performed by the base station or Integrated access and backhaul-Distributed Units (IAB-DU), Non-Terrestrial Network (NTN) , relay, and repeater. Further, explanation is provided with respect to the BS.

[0054] In an embodiment, the BS performs a method for CSI measurements for the network- enabled with SBFD. The BS at first sends at least one first configuration of SBFD to the at least second node (for example UE, relay, Integrated access, and backhaul-Mobile Termination (IAB-MT) and repeater). Further, the BS sends at least one second configuration for CSI reporting. Further, the BS receives at least one group from a plurality of groups and at least one CSI parameter of the at least one group in at least one CSI report based on a priority.

[0055] According to some embodiment, the priorities are assigned by one of BS and the at least one second node to the plurality of groups and to at least one CSI parameter of each group from the plurality of groups. In an embodiment, the plurality of groups is formed by one of at least one the BS and at least one second node using at least one CSI parameter for SBFD and NSBFD symbols.

[0056] According to an embodiment, the BS determines the uplink (UE) resources for receiving the at least one CSI report. Further, the BS determines dropping of at least one of the groups and at least one CSI parameter of the at least one remaining group from the CSI report based on the priorities, when the uplink (UL) resources for receiving the at least oneCSI report are not sufficient; and receives the remaining groups of the plurality of groups and at least one remaining CSI parameters of the remaining groups in at least one CSI report.

[0057] According to some embodiment, the BS determines the uplink (UL) resources for receiving the at least one CSI report. Further, the BS receives at least one group chosen from the plurality of groups and at least one CSI parameters of the at least one group in at least one CSI report. Further, the BS determines dropping of the remaining groups of the plurality of groups and dropping of the at least one remaining CSI parameters of the at least one group received by the at least first node from the at least one CSI report based on the priorities, when the uplink (UL) resources for receiving the at least one CSI report are not sufficient.

[0058] According to an embodiment, the BS receives the CSI report according to a priority configured for the at least one CSI report when UL resources are not sufficient. In an embodiment, the BS receives the at least one CSI parameter separately in at least one CSI report for SBFD and in at least one CSI report for NSBFD symbols.

[0059] According to an embodiment, the BS receives the at least one group and at least one CSI parameter of the at least one group in a pre-determined order in the at least one CSI report. According to an embodiment, the plurality of groups is formed by dividing the at least one CSI parameter into at least one set consisting of at least one CSI parameter. In an embodiment, the at least one set of at least one CSI parameter comprises at least one of part 1 CSI measurements and part 2 CSI measurements.

[0060] Various examples of parameters that can be included in the part 1 and part 2 CSI measurement are explained in the above paragraphs. Further, various priority assigning rules are also explained in detail in the above sections. Therefore, for the sake of brevity, the same has been omitted here.

[0061] According to an embodiment, the BS does not receive at least one of at least one group from the plurality of groups and the at least one CSI parameter from at least one remaining group from the plurality of groups in one of the ascending order and descending order of the assigned priorities, when the UL resources are not sufficient.

[0062] According to some embodiment, the BS does not receive all the at least one CSI parameter with the same priority in the order.

[0063] According to some embodiment, the BS does not receive all the at least one CSI parameter for both SBFD and NSBFD symbols when the UL resources are not sufficient to transmit all the at least one CSI parameter.Impact of SBFD on CSI processing unit (CPU) Occupancy

[0064] In general, the CSI measurement and reporting requires processing and computation in the UE. The UE needs to have enough capability to receive CSI-RS resources, process them and report the CSI report. E.g., they need to have enough CPU and memory to receive CSI-RS resources, compute CSI parameters corresponding to a CSI report configuration and report the parameters. Further, the requirement increases in case the UE is configured with multiple CSI reports and / or report for separate parameters for SBFD and non-SBFD scenario. In case of a UE configured by higher layers CSI-ReportConfig, the CPU is occupied for certain OFDM symbols depending on report quantity, the number of CSI-RS resources configured under CSI-ReportConfig, type of CSI-RS resource, CSI report type, etc.• A periodic or semi-persistent CSI report occupies CPU(s) from the first symbol of the earliest one of each CSI-RS / CSI-IM / SSB resource for channel or interference measurement, respective latest CSI-RS / CSI-IM / SSB occasion no later than the corresponding CSI reference resource, until the last symbol of the configured PUSCH / PUCCH carrying the report.• An aperiodic CSI report occupies CPU(s) from the first symbol after the PDCCH triggering the CSI report until the last symbol of the scheduled PUSCH carrying the report.• An initial semi-persistent CSI report on PUSCH after the PDCCH trigger occupies CPU(s) from the first symbol after the PDCCH until the last symbol of the scheduled PUSCH carrying the report.

[0065] According to an embodiment, in the case of UE reporting separate parameters for SBFD and non-SBFD scenario in same report based on the CSI-RS resources received in SBFD and non-SBFD symbols, the following cases need to be considered:• The UE receives at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IM occasion for interference measurement for non-SBFD symbols and the UE also receives at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IM occasion for interference measurement for SBFD symbols separately. The UE transmits joint CSI report, to the BS where the UE includes CSI parameters corresponding to SBFD and non-SBFD scenario separately in the joint report based on a pattern. The pattern for including the CSI parameters corresponding to non-SBFD and SBFD scenarios in the report is defined in standards based on the priority of the SBFD and non-SBFD scenarios. For e.g., CSI parameters corresponding to SBFD scenario when configured with high priority is included first in starting symbols of the PUSCH / PUCCH carrying the report then the CSI parameters corresponding to the non-SBFD symbol with lower priority is included later in the remaining symbols of the PUSCH / PUCCH carrying the report. The pattern for including CSI parameters corresponding to non-SBFD and SBFD scenarios in the report can also be configured to the UE using an RRC parameter. For e.g., if a one -bit RRC parameter SBFDreportMapping = 1 is configured, the UE includes the CSI parameters corresponding to non-SBFD first in the starting symbols of PUSCH / PUCCH carrying the report, otherwise the CSI parameters corresponding to SBFD is included first. In this scenario, the following options for CPU computation can be considered. Table 9 shows an example of the scenario considered in below methods of CPU occupancyTable 9- E.g. of separate CSI-RS resources for Non-SBFD & SBFD symbols and separate inclusion of CSI parameters of Non-SBFD(symbols 1,2,3, this portion of the report ends atT3) and SBFD(symbols 4,5 here this portion of the report ends at T4) in same report (Total symbos are 5 i.e. report ends at time Ta=T4).

[0066] According to an embodiment, in one option, separate CPU computation is defined for SBFD and non-SBFD symbol types based on their respective CSI-RS transmission occasions along with the pattern for including their corresponding CSI parameters in the report. For e.g., when the CSI parameters corresponding to non-SBFD case is included first in the starting symbols of the PUSCH / PUCCH carrying the report and later the parameters corresponding to the SBFD case are included in the remaining symbols of the PUSCH / PUCCH carrying the report, the CPU occupation for non-SBFD case (CPUoccupationl) will be calculated from the first symbol of earliest one of CSI-RS / CSI- IM transmission occasions in non-SBFD symbols until the last symbol of the portion of the PUSCH / PUCCH which occupies only the parameters corresponding to non-SBFD case. Similarly, the CPU occupation in SBFD case (CPUoccupation2) will be calculated from the first symbol of earliest one of CSI-RS / CSI-IM transmission occasions in SBFD symbols until the last symbol of the PUSCH / PUCCH carrying the report.

[0067] According to an embodiment, in another option separate CPU computation is defined for SBFD and non-SBFD symbol types based only on the pattern for including their corresponding CSI parameters in the report without considering their associated CSI-RS transmission occasions. For e.g., when the CSI parameters corresponding to non-SBFD case is included first in the starting symbols of the PUSCH / PUCCH carrying the report and later the parameters corresponding to the SBFD case are included in remaining symbols of the PUSCH / PUCCH carrying the report, the CPU occupation for non-SBFD case (CPUoccupationl) will be calculated from the first symbol of earliest one of all CSI- RS / CSI-IM transmission occasions in non-SBFD or SBFD symbols until the last symbol of the portion of the PUSCH / PUCCH which occupies only the parameters corresponding to non-SBFD case. Whereas the CPU occupation in SBFD case (CPUoccupation2) will be calculated from the first symbol of earliest one of all CSI-RS / CSI-IM transmission occasions in non-SBFD or SBFD symbols (as used for calculation of CPUoccupationl) until the last symbol of the PUSCH / PUCCH carrying the report.

[0068] According to an embodiment, in one option, separate CPU computation is defined for SBFD and non-SBFD symbol types based on their respective CSI-RS / CSI-IMtransmission occasions only without considering the pattern for including their corresponding CSI parameters in the report. For e.g., CPU occupation (CPUoccupationl) for non-SBFD symbol will be calculated from the first symbol of earliest one of CSI- RS / CSI-IM transmission occasions in non-SBFD symbols until the last symbol of the PUSCH / PUCCH carrying the report. Similarly, the CPU occupation (CPUoccupation2) for SBFD symbol type will be calculated from the first symbol of earliest one of CSI-RS / CSI- IM transmission occasions in SBFD symbols until the last symbol of the PUSCH / PUCCH carrying the report.

[0069] According to an embodiment, in yet another option a joint CPU occupation is calculated for both SBFD and non-SBFD case. For e.g. the CPU occupation is calculated from the first symbol of earliest one of all CSI-RS / CSI-IM transmission occasions associated with the report configuration irrespective of association with non-SBFD or with SBFD scenarios until the last symbol of the PUSCH / PUCCH carrying the report.

[0070] According to an embodiment, the UE is receiving at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IM occasion for interference measurement for non-SBFD symbols and the UE is also receiving at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IM occasion for interference measurement for SBFD symbols separately. The UE transmits a common CSI report, containing CSI parameters corresponding to SBFD and non-SBFD scenario to the BS based on the report configuration. Table 10 illustrates an example of the scenario considered in methods below of CPU occupancy.Table 10 - E.g. of separate CSI-RS resources for Non-SBFD & SBFD symbols and mixed(i.e. not specifically separated in time) inclusion of CSI parameters of Non-SBFD and SBFD in same report (Total symbos are 5 i.e. report ends at time Ta).

[0071] In this scenario, following options for CPU computation are considered:• In one option, separate CPU computation is defined for SBFD and non-SBFD symbol types based on their respective CSI-RS / CSI-IM transmission occasions. The CPU occupation for non-SBFD case will be calculated from the first symbol of earliest one of CSI-RS / CSI-IM transmission occasions associated with non-SBFD symbols until the last symbol of the PUSCH / PUCCH carrying the report. Similarly, the CPU occupation for measurement of CSI in SBFD case will be calculated from the first symbol of earliest one of CSI-RS / CSI-IM transmission occasions associated with SBFD symbols until the last symbol of the PUSCH / PUCCH carrying the report. E.g., Two CPU occupations, CPUoccupationl for SBFD symbol type and CPUoccupation2 for non-SBFD symbol type will be calculated, when UE receives at least one CSI-RS transmission occasion in SBFD symbols and at least one CSI- RS transmission occasion in non-SBFD symbols respectively.• In another option a joint CPU occupation is calculated for both SBFD and non-SBFD case. For e.g. the CPU occupation is calculated from the first symbol of earliest one of all CSI-RS / CSI-IM transmission occasions associated with the report configuration irrespective of association with non-SBFD or with SBFD scenarios until the last symbol of the PUSCH / PUCCH carrying the report.

[0072] According to an embodiment, in the case of UE reporting separate parameters for SBFD and non-SBFD scenario in same report based on the common CSI-RS resources received in SBFD and non-SBFD symbols. The UE is receiving, at least one CSI-RS transmission occasion for channel measurement and CSI-RS and / or CSI-IM occasion for interference measurement for both non-SBFD and SBFD symbols. Table 11 illustrates an example of the scenario considered in below methods of CPU occupancy.Table 11-E.g. of Common CSI-RS resources for Non-SBFD & SBFD symbols and mixed(i.e. not specifically separated in time) inclusion of CSI parameters of Non-SBFD and SBFD in same report (Total symbols are 5 i.e. report ends at time Ta).

[0073] In this case the UE transmits a joint CSI report, containing CSI parameters corresponding to both SBFD and non-SBFD scenario, to the BS based on the CSI report configuration.

[0074] A joint CPU occupation is calculated for both SBFD and non-SBFD case. For e.g. the CPU occupation is calculated from the first symbol of earliest one of all common CSI-RS / CSI-IM transmission occasions for non-SBFD and SBFD scenarios until the last symbol of the PUSCH / PUCCH carrying the report.

[0075] According to an embodiment, Table 12 illustrates an extension of Table 11, with joint report with separate inclusion of CSI parameters of SBFD & Non SBFD in separately time domain. As shown in Table 12, CPU Occupancy in following ways:• Tx to T4 common for both SBFD & Non SBFD (as explained in the previous section).• Separate for SBFD & Non SBFD, i.e. CPU occupancy for Non-SBFD is (Tx to T3), and for SBFD is (Tx to T4).Table 11- E.g. of Common CSI-RS resources for Non-SBFD & SBFD symbols and separate inclusion of CSI parameters of Non-SBFD(symbols 1,2,3, this portion of the report ends at T3) and SBFD(symbols 4,5 here this portion of the report ends at T4) in same report (Total symbos are 5 i.e. report ends at time Ta=T4).

[0076] FIG. 5 illustrates a method 500 for computing CPU occupancy time by at least one node, according to an embodiment of the present disclosure. In an embodiment, the at least one node is one of a user equipment (UE), relay, IAB-MT, IAB-DU, BS, and repeater. Further, explanation is provided with respect to the UE while communicating with a BS, however, the method can be performed by the relay, Non-Terrestrial Network (NTN), Integrated access and backhaul-Mobile Termination (IAB-MT), Integrated access and backhaul-Distributed Units (IAB-DU), BS, and repeater.

[0077] According to an embodiment, at step 501, the UE receives at least one configuration of SBFD. Further, at step 503, the UE receives at least one of at least one channel state information (CSI) reference signal (CSI-RS) transmission occasion for channel measurement and at least one CSI interference measurement (CSI-IM) occasion for interference measurement in at least one of sub-band full duplexing (SBFD) and non-SBFD (NSBFD) symbols. Further, at step 505, the UE determines a pattern for including at least one CSI report quantity of at least one of SBFD and NSBFD symbols, in at least one CSI report. Further, at step 507, the UE computes a CPU occupancy time, for transmitting the at least one CSI report based on the pattern. As an example, the at least one CSI report quantity comprises at least one of: Channel Quality Indicator (CQI), Channel Rank Indicator (CRI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Precoding Matrix Indicator (PMI), Eayer indicator (FI), Rank Indicator (RI) and Signal-to-Interference-plus-Noise Ratio (SINR).

[0078] In an embodiment, to transmit the at least one CSI report, the UE measures a separate at least one of CSI-RS and CSI-IM transmission occasions for the NSBFD symbols and SBFD symbols. Further, the UE include, include the at least one CSI report quantity in the at least one CSI report.

[0079] According to an embodiment, the UE generates the at least one CSI report by one of jointly and separately for the NSBFD symbols and SBFD symbols. In an embodiment, the at least one CSI report is transmitted in one of a PUSCH or a PUCCH.

[0080] In an embodiment, the pattern includes the at least one CSI report quantity corresponding to NSBFD symbols in the starting symbols of the at least one CSI report, followed by the at least one CSI report quantity corresponding to the SBFD symbols in the remaining symbols of the at least one report.

[0081] In an embodiment, the UE computes the CPU occupancy time by calculating a CPU computation time for the NSBFD symbols, from one of the CSI-RS and the CSI-IM transmission occasions in the NSBFD symbols till the last portion of one of the PUSCH and the PUCCH occupying the at least one CSI report quantity corresponding to NSBFD.

[0091] In general, the CSI-RS resources need to be received at the UE for the CSI measurement and reporting. The UE needs to have enough capability (e.g., memory) to receive the CSI-RS resources and the associated ports for the measurements. The maximum number active CSI-RS ports or active CSI-RS resources which can be supported at the UE are reported as UE capability by the UE to the BS. For e.g., per-CC capabilities on simultaneous active CSI-RS resources and simultaneous active CSI-RS ports for typical UEs operating in the field is reported as maxNumberSimultaneousNZP-CSI-RS-PerCC = 4 and totalNumberPortsSimultaneousNZP-CSI-RS-PerCC = 32. Further, if a UE is configured with one or more CSI Reporting Settings, where a CSI-RS resource is referred N times by the report settings, the CSI-RS resource and the CSI-RS ports within the CSI- RS resource are counted N times. The requirement of active CSI-RS resources and active CSI-RS ports increases in case the UE is configured to report separate CSI parameters for SBFD and non-SBFD scenarios. For e.g., the UE is configured with a report configuration comprising two subconfigurations, for SBFD and non-SBFD symbol types, where each sub configuration is associated with at least one CSI-RS resource. The following cases need to be considered.

[0092] The UE receives at least one CSI-RS resource for channel measurement for non- SBFD symbols and at least one CSI-RS resource for channel measurement for SBFD symbols separately or the UE receives at least one CSI-RS resource for channel measurement for both SBFD symbols and non-SBFD symbols. The total number of active CSI-RS resources and total number of active CSI-RS ports corresponding to both SBFD and non-SBFD increases. In this scenario, following options for can be considered for the CSI- RS resource and ports counting:• In one option, a common UE capability of active CSI-RS resources and a common UE capability of active CSI-RS ports is reported for both SBFD and non-SBFD scenarios.a. In one method, existing range of values for the UE capabilities are reported, but this may restrict the flexibility in transmissions of CSI-RS at BS. For e.g., a BS can’t configure more than 16 ports for each of the two subconfigurations for SBFD and non-SBFD symbol types. New parameters for the UE capabilities with existing values are defined to support SBFD techniques. In another way, existing UE capability parameters can be reused for corresponding UE capabilities of active CSI-RS resources and active CSI-RS ports to support SBFD techniques. b. In another method, new capabilities with higher values are defined for supporting the SBFD technique. A UE capable of supporting SBFD technique will report the UE capabilities of active CSI-RS resources and active CSI-RS ports with higher values than their existing legacy values. New parameters for the UE capabilities with higher values are defined to support SBFD techniques. For e.g., maxNumberSimultaneousNZP-CSFRS- PerCC-SBFD and totalNumberPortsSimultaneousNZP-CSI-RS-PerCC- SBFD.• In another option, separate capabilities are reported by the UE for both SBFD and non-SBFD scenarios. New parameters for the UE capabilities can be defined to support the individual values for SBFD and non-SBFD scenarios. For e.g., a set of maxNumberSimultaneousNZP-CSI-RS-PerCC-SBFD and totalNumberPortsSimultaneousNZP-CSI-RS-PerCC-SBFD is reported for SBFD symbols and another set of maxNumberSimultaneousNZP-CSFRS-PerCC- nonSBFD and totalNumberPortsSimultaneousNZP-CSI-RS-PerCC-nonSBFD. is reported for non-SBFD symbols. c. In a method, the existing range of values for each of the UE capabilities are reported for their counterparts to support the SBFD technique. d. In another method, new values can be defined for each of the new UE capability parameters for SBFD scenario and for each of the new UE capability parameters for non-SBFD scenario.

[0093] In case of the UE is receiving at least one CSI-RS resource for channel measurement that is common for both non-SBFD symbols and SBFD symbols. For e.g., in the case of UEconfigured with 2 subconfigurations i.e. sub -configuration! and sub-configuration2 within a CS I- ReportConfig for CSI measurements on SBFD and non-SBFD time resources such as symbols, a CSI- RS resource can be referred to by both subconfiguration 1 and subconfiguration2 associated with non-SBFD and SBFD respectively. The total number of active CSI-RS resources and total number of active CSI-RS ports corresponding to both SBFD and non-SBFD increases based on the counting of the common CSI-RS resources. In this scenario, following options for can be considered for the CSI-RS resource and ports counting:• In one method, the common CSI-RS resources and their associated CSI-RS ports are counted twice. For e.g., the common CSI-RS resources which is referred by both subconfiguration 1 and subconfiguration2 associated with non-SBFD and SBFD symbols respectively are counted twice in calculating the simultaneous CSI-RS resources counting and the associated ports are also counted twice in active CSI-RS ports calculation. In another example, if a CSI-RS resource with 8 ports is referred to by both the subconfigurations for SBFD and non-SBFD scenarios, the CSI-RS resource and its associated CSI-RS ports is counted twice and the number of active CSI-RS resources and active CSI-RS ports will be 2 and 16(8*2=16) respectively. However, this method of counting will increase the count of total CSI-RS resources and their associated CSI-RS ports.• In another method, the common CSI-RS resources and their associated CSI-RS ports are counted once. For e.g., the common CSI-RS resources which is referred by both subconfiguration 1 and subconfiguration2 associated with non-SBFD and SBFD symbols respectively are counted only once in counting the simultaneous CSI-RS resources and the associated ports are also counted only once in active CSI-RS ports calculation for both the subconfigurations. In another example, if a CSI-RS resource with 8 ports is referred by both the subconfigurations for SBFD and non-SBFD scenarios, the CSI-RS resource and its associated CSI-RS ports is counted once, and the number of active CSI-RS resources and active CSI-RS ports will be 1 and 8 respectively. However, this method of counting will increase the count of total CSI- RS resources and their associated CSI-RS ports.

[0101] According to an embodiment, the UE is configured with at least one report configuration, wherein the at least one report configuration comprises at least one of at least one subconfiguration for SBFD symbols and at least one subconfiguration for non-SBFD symbols, wherein the at least one subconfiguration is associated with at least one CSI-RS resource.

[0102] In an embodiment, the CSI-RS resources and the associated CSI-RS ports are counted one of once and twice depending on the at least one of at least one first CSI resource configuration, at least one second CSI resource configuration, at least one third CSI resource configuration and the at least one report configuration. According to an embodiment , the UE reports at least one of at least one CSI measurement and at least one CSI report. Further, the at least one CSI-RS resource is an active CSI-RS and the associated at least one CSI-RS port is an active port.

[0103] The forthcoming paragraphs will explain the method 600 when performed by the base station or Integrated access and backhaul-Distributed Units (IAB-DU), Non-Terrestrial Network (NTN), relay, and repeater. Further, explanation is provided with respect to the BS. In particular, the BS performs the method for receiving the UE capabilities.

[0104] In an embodiment, at first the BS receives at least one parameter related to UE capability of active CSI-RS resources and active ports for at least one of sub-band full duplexing (SBFD) and non-SBFD (NSBFD). Further, the BS transmits one of at least oneof at least one first CSI resource configuration for channel measurements for SBFD symbols and at least one second CSI-RS resource configuration for the channel measurements for non-SBFD (NSBFD) symbols, or at least one third CSI resource configuration for the channel measurement common for both the SBFD symbols and NSBFD symbols.

[0105] According to an embodiment, the BS transmission depends on the at least one parameter related to UE capability.

[0106] According to some embodiment, tthe at least one parameter comprises one of a common UE capability of at least one of active CSI-RS resources and active ports for both SBFD and NSBFD symbols, and a separate UE capability of at least one of active CSI-RS resources and active ports for SBFD and NSBFD symbols.

[0107] According to an embodiment, the BS received the at least one parameter using at least one of a first range of values, wherein the first range of values indicating the capabilities of the legacy UE, and a second range of values indicating the capabilities of the UE supporting SBFD techniques, wherein second range of values are higher than the first range.

[0111] According to an embodiment, the BS receives at least one of at least one CSI measurement and at least one CSI report.

[0112] Thus, in SBFD communication, a separate measurement and reporting of channel parameters for SBFD active and SBFD inactive resources causes increment in processing and computation at the UE and creates lack of UL resource for CSI reporting.
