Description

Technical Field

[0001] Various example embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to methods, devices, apparatuses, and computer-readable storage media for channel state information (CSI) reporting. Background Art

[0002] In Release 18 of the 3rd Generation Partnership Project (3GPP), one of the goals is to specify spatial domain adaptation using different antenna elements and CSI ports for network energy saving (NES) for New Radio (NR). When a UE is configured with multiple spatial domain adaptation modes, the UE can report CSI for these modes.

[0003] So far, some agreements have been reached on CSI reporting configurations for a spatial domain adaptation framework, where the CSI reporting configuration can be used for spatial domain adaptation purposes, including multiple CSI reporting subconfigurations, and each subconfiguration corresponds to a spatial adaptation mode. And the UE performs CSI reporting for each of the subconfigurations within the CSI reporting configuration. Since the transmission resources configured for CSI reporting are limited, it is expected to further discuss how to report CSI associated with multiple CSI reporting subconfigurations.

The embodiments of the present disclosure can be applied to various communication systems. In view of the rapid development of communication, there are of course future types of communication technologies and systems that can implement the present disclosure. It should not be considered that the scope of the present disclosure is limited to the above-mentioned system.

[0038] As used herein, the term "network device" refers to a node in a communication network via which a terminal device accesses a network and receives services from it. A network device may refer to a base station (BS) or an access point (AP), such as a NodeB (NodeB or NB), an evolved NodeB (eNodeB or eNB), an NRNB (also known as a gNB), a remote radio unit (RRU), a radio head (RH), a remote radio head (RRH), a repeater, an integrated access and backhaul (IAB) node, a low-power node (such as a femto, a pico), a non-terrestrial network (NTN) or non-terrestrial network equipment, such as satellite network equipment, a low earth orbit (LEO) satellite and a geosynchronous orbit (GEO) satellite, an aircraft network equipment, etc., depending on the terminology and technology applied. In some example embodiments, a radio access network (RAN) split architecture includes a centralized unit (CU) and a distributed unit (DU) at an IAB host node. An IAB node includes a mobile terminal (IAB-MT) portion that behaves like a UE toward a parent node, and a DU portion of an IAB node behaves like a base station toward a next-hop IAB node.

[0039] The term "terminal device" refers to any terminal device capable of wireless communication. As an example and not limitation, a terminal device may also be referred to as a communication device, a user equipment (UE), a user station (SS), a portable subscriber station, a mobile station (MS), or an access terminal (AT). The terminal device may include, but is not limited to, a mobile phone, a cellular phone, a smart phone, a voice over IP (VoIP) phone, a wireless local loop phone, a tablet computer, a wearable terminal device, a personal digital assistant (PDA), a portable computer, a desktop computer, an image capture terminal device such as a digital camera, a game terminal device, a music storage and playback device, a vehicle-mounted wireless terminal device, a wireless endpoint, a mobile station, a laptop embedded device (LEE), a laptop mounted device (LME), a USB dongle, a smart device, a wireless customer premises equipment (CPE), an Internet of Things (IOT) device, a watch or other wearable, a head mounted display (HMD), a vehicle, a drone, a medical device and an application (e.g., remote surgery), an industrial device and an application (e.g., a robot and / or other wireless devices operating in an industrial and / or automatic processing chain environment), a consumer electronic device, a device operating on a commercial and / or industrial wireless network, etc. The terminal device may also correspond to the mobile terminal (MT) part of an IAB node (eg, a relay node).In the following description, the terms "terminal device", "communication device", "terminal", "user equipment" and "UE" may be used interchangeably.

[0040] As used herein, the terms "resources", "transmission resources", "resource blocks", "physical resource blocks" (PRBs), "uplink resources" or "downlink resources" may refer to any resources used to perform communication (e.g., communication between a terminal device and a network device), such as time domain resources, frequency domain resources, spatial domain resources, code domain resources, or any other resources that enable communication.

[0041] Hereinafter, resources in the time domain will be used as examples of resources for describing some example embodiments of the present disclosure. It should be noted that the example embodiments of the present disclosure are also applicable to other resources in other domains. In summary, the resources used herein include, but are not limited to, time resources or frequency resources, such as full-duplex time resources with non-overlapping subbands, dynamic time division duplex time resources, full-duplex evolution time resources, subbands, subcarriers, or resource elements (REs).

[0042] Generally speaking, when a terminal device communicates with a network device, the terminal device needs to report CSI feedback to the network device so that the network device can understand the transmission channel conditions and make more appropriate decisions for subsequent packet scheduling, modulation and coding adaptation, and multiple-input multiple-output (MIMO) related transmission adaptation. In traditional specifications, only the level of CSI report configuration is specified, where the mapping order of CSI fields is within a CSI report. More details on how to map the CSI fields of a reported CSI are discussed as follows.

[0043] If only wideband channel quality indicator (CQI) / precoding matrix indicator (PMI) is reported: that is, when the physical uplink control channel (PUCCH) carries type I CSI with wideband frequency granularity, the CSI payload carried by PUCCH format 2 and PUCCH format 3 or 4 is consistent and the same, regardless of the rank indicator (RI) (if reported) and the CSI-RS resource indicator (CRI) (if reported).

[0044] Table 1 below illustrates an example mapping order of CSI fields of a CSI report.

[0045] Table 1

[0046]

[0047] In Table 1, pmi-FormatIndicator=widebandPMI and cqi-FormatIndicator=widebandCQI or reportQuantity is set to "cri-RI-CQI" and cqi-FormatIndicator=widebandCQI.

[0048] Further, if subband CQI / PMI also needs to be reported together with wideband CQI / PMI: that is, for type I CSI subband reporting on PUCCH format 3 or 4, the payload is divided into two parts. The first part contains RI (if reported), CRI (if reported), CQI for the first codeword. The second part contains PMI (if reported), L1 (if reported), and CQI for the second codeword when RI>4 (if reported).

[0049] Table 2 below shows another example mapping order of CSI fields of one CSI report (CSI part 1), where pmi-FormatIndicator=subbandPMI or cqi-FormatIndicator=subbandCQI.

[0050] Table 2

[0051]

[0052] Table 3 below shows another example mapping order of CSI fields for one CSI report, CSI part 2 wideband, where pmi-FormatIndicator=subbandPMI or cqi-FormatIndicator=subbandCQI.

[0053] Table 3

[0054]

[0055] Table 4 below shows another example mapping order of CSI fields for one CSI report (CSI part 2 subband), where Pmi-FormatIndicator=subbandPMI or cqi-FormatIndicator=subbandCQI.

[0056] Table 4

[0057]

[0058] In some embodiments, the subbands for a given CSI report n indicated by a higher layer parameter csi-ReportingBand having a value set to '1' are numbered consecutively in increasing order, with the lowest subband having csi-ReportingBand set to a value of '1' as subband 0.

[0059] If the CSI report transmitted on the PUCCH is not two parts, the mapping order of the CSI report and the UCI bit sequence is as indicated in Table 5 below.

[0060] Table 5

[0061]

[0062] Table 5 above shows that in the absence of a two-part CSI report, the CSI report is a UCI bit sequence a0, a1, a2, a3, ..., a A-1 In addition, in Table 5, if at least one of the CSI reports transmitted on the PUCCH is two-part, two UCI bit sequences are generated. as well as In Table 6.3.1.1.2-13, all CSI fields of the CSI report are mapped to Starting UCI bit sequence The most significant bit of each field is mapped to the lowest order information bit of that field, for example, the most significant bit of the first field is mapped to In Table 6.3.1.1.2-14, in order from top to bottom, the CSI fields of all CSI reports are mapped to the following Starting UCI bit sequence The most significant bit of each field is mapped to the lowest order information bit of that field, for example, the most significant bit of the first field is mapped to If the UCI bit sequence If the length of the UCI bit sequence is less than 3 bits, zeros are appended to the UCI bit sequence until its length is equal to 3.

[0063] If at least one of the CSI reports for transmission on the PUCCH has two parts, two UCI bit sequences are generated, and the mapping order of the CSI reports to the UCI bit sequences is specified using Table 6 below.

[0064] Table 6

[0065]

[0066] Table 6 above shows the CSI report to UCI bit sequence , which has a two-part CSI report. In Table 6, CSI report #1, CSI report #2, ..., CSI report #n correspond to CSI reports in increasing order of CSI report priority values.

[0067] Table 7 below shows an example mapping order of CSI reports to UCI bit sequences for a two-part CSI report.

[0068] Table 7

[0069]

[0070] In Table 7, CSI report #1, CSI report #2, ..., CSI report #n correspond to CSI reports in ascending order of CSI report priority values.

[0071] It can be seen that for CSI reports transmitted on PUCCH, if all CSI reports consist of one part, the UE can omit a part of the CSI report. The omission of CSI is done according to the priority order determined from the priority value. CSI reports are omitted starting from the lowest priority until the CSI report code rate is less than or equal to that configured by the higher layer parameter maxCodeRate.

[0072] If any CSI report consists of two parts, the UE may omit a part of the Part 2 CSI. The omission of Part 2 CSI may be performed according to the priority order. Part 2 CSI is omitted starting from the lowest priority level until the Part 2 CSI code rate is less than or equal to the code rate configured by the higher layer parameter maxCodeRate.

[0073] As described above, it has been agreed to support a CSI reporting configuration for a spatial adaptation framework, wherein a CSI reporting configuration may be used for spatial adaptation purposes, including multiple CSI reporting subconfigurations, and each subconfiguration corresponds to a spatial adaptation mode.

[0074] By introducing "sub-configurations" in the CSI reporting configuration, how the corresponding uplink control information (UCI) mapping and prioritization should be handled is one aspect of this feature that needs to be addressed.

[0075] Regarding how to support sub-configuration based CSI reporting, several implementations may be performed.

[0076] For N (>1) CSI reports based on a CSI report configuration, the CSI mapping order and CSI omission / priority rules for CSI part 1 or part 2 may be performed for each CSI report. Specifically, for CSI part 1, CSI quantities corresponding to all N subconfigurations (such as CSI reference signal (CSI-RS) resource index (CRI), rank indicator (RI), and channel quality indicator (CQI), as applicable) are multiplexed into part 1 of a single CSI, and the mapping order thereof may be determined, for example, as CSI quantity first, subconfiguration index second, or as subconfiguration index first, CSI quantity second. For CSI part 2, two priority reporting levels may be assigned to the CSI report, where each priority reporting level is determined, for example, as even subbands for all N subconfigurations for a priority reporting level and odd subbands for all N subconfigurations for a second priority reporting level), and conventional mechanisms may be reused for CSI omission.

[0077] Alternatively, for N (>1) CSI reports based on the CSI reporting configuration, the CSI mapping order and CSI omission / priority rules for CSI part 1 or part 2 may be performed for each sub-configuration. Specifically, for CSI part 1, the CSI quantities (such as CRI, RI, and CQI, as applicable) corresponding to each sub-configuration are generated separately and then concatenated into a single bit sequence for CSI part 1 of the CSI reporting configuration. For CSI part 2, two priority reporting levels may be assigned to each sub-configuration, i.e., a total of 2×N priority reporting levels. Further, for the CSI omission / priority rules, additional consideration of the sub-configuration index is required, and the priority value may be determined as Pri iCSI (y, k, c, s, q) = 2·q max ·N cells ·M s y+q max ·N cells ·M s ·k+q max ·M s ·c+q max s+q, where q is the subconfiguration index and q max is the maximum number of sub-configuration indices in the CSI reporting configuration, y=0 for aperiodic CSI reports to be carried on PUSCH, y=1 for semi-persistent CSI reports to be carried on PUSCH, y=2 for semi-persistent CSI reports to be carried on PUCCH, and y=3 for periodic CSI reports to be carried on PUCCH; k=0 for CSI reports carrying L1-RSRP or L1-SINR, and k=1 for CSI reports not carrying L1-RSRP or L1-SINR; c is the serving cell index, and N cells is the value of the higher-layer parameter maxNrofServingCells; s is reportConfigID, and Ms is the value of the higher-layer parameter maxNrofCSI-ReportConfiguration.

[0078] Alternatively, for N (>1) CSI reports based on a CSI report configuration, the CSI mapping order and CSI omission / priority rules for CSI part 1 or part 2 may be performed as follows. For CSI part 1, CSI quantities (e.g., CRI, RI, and CQI, when applicable) associated with a reference subconfiguration may be included, where the reference subconfiguration may, for example, be a subconfiguration with a maximum number of antenna ports based on corresponding (N1, N2) values, where N1 is the number of antennas (ports) in the first dimension and N2 is the number of antennas (ports) in the second dimension. Further, for CSI part 2, the remaining CSI quantities of the reference subconfiguration (e.g., PMI, LI) and the (N-1) CSI of the remaining subconfigurations may be included.

[0079] Note that if CSI payload reduction is supported, the payload of the corresponding CSI amount is determined to be, for example, omitted, distinguished, etc.

[0080] For aperiodic and semi-persistent CSI reporting, there is an option for the gNB to request CSI reports only for a subset of all configured spatial domain adaptation patterns (e.g., for a CSI reporting configuration, the UE may be configured with a total of L sub-configurations, where each sub-configuration maps to a spatial adaptation pattern, and the UE may be instructed via downlink control information (DCI) or media access control-control element (MAC-CE) to make CSI reports for N out of the total L adaptation patterns, i.e., 2 out of a total of 5 configured spatial domain adaptation patterns reported by the UE).

[0081] However, for periodic CSI reporting, based on the current agreement reached, the UE must report L sub-configurations corresponding to all configurations of different modes in the reporting occasion. Although for this implementation, it is not entirely certain how many modes with sub-configurations can be considered more suitable and conducive to fast adaptation. In practice, the PUCCH capacity carrying UCI can be quite limited. And for other operating main configurations, the increased number of modes should not harm the existing (legacy) CSI reporting. Therefore, the existing CSI-reporting priorities should not be greatly disturbed by reports from multiple adaptation modes.

[0082] If the CSI mapping order is performed based on the sub-configuration and the new CSI report priority rule, the legacy approach and the legacy CSI report priority rule should be redefined, which is not desirable. Thus, it is preferred that the CSI mapping order can be performed for each CSI report, and thus the legacy approach and the legacy CSI report priority rule can be reused.

[0083] In the present disclosure, a mapping order of CSI fields within a CSI report containing multiple sub-configurations is proposed. According to the present disclosure, a first device (e.g., a terminal device) receives a CSI report configuration from a second device (e.g., a network device), the CSI report configuration comprising: a first sub-configuration associated with a first priority reporting level; and a second sub-configuration associated with a second priority reporting level lower than the first priority reporting level; and a CSI report associated with the first and second sub-configurations is sent to the second device and at least partially based on the first and second first priority reporting levels. In this way, the impact on other CSI reports caused by the introduction of sub-configurations will be minimized.

[0084] In the present disclosure, a CSI report configuration associated with multiple sub-configurations may refer to: a CSI report configuration including multiple sub-configurations, or a CSI report configuration including multiple value groups / value sets. In other words, each sub-configuration may be represented as an independent configuration, or as a value group / value set.

[0085] In the present disclosure, there is a relationship between sub-configuration and CSI sub-configuration reporting. In view of this, the discussion on sub-configuration can be adapted to CSI sub-configuration reporting, for example, the prioritization / deprioritization of sub-configuration can be replaced by the prioritization / deprioritization of CSI sub-configuration reporting. For the sake of brevity, some similar content is omitted here.

[0086] It should be understood that the NES scenario will particularly benefit from the example embodiments of the present disclosure. However, it does not mean that the example embodiments of the present disclosure can be implemented only for this specific scenario. In fact, the preferred embodiments of the present disclosure can be implemented in any scenario where the sub-configuration-based method is applied. The present disclosure is not limited in this regard.

[0087] In this disclosure,

[0088] The terms “CSI associated with a subconfiguration”, “CSI subconfiguration report”, “CSI subreport”, and “CSI field” may be used interchangeably;

[0089] The terms "ID," "index," "indicator," and "identifier" may be used interchangeably.

[0098] Working principles and example signaling for communication

[0099] refer to Figure 2 , which shows a signaling flow 200 of a communication according to some embodiments of the present disclosure. For the purpose of discussion, reference will be made to Figure 1 The signaling flow 200 is discussed, for example, by using the first device 110 and the second device 120 .

[0100] It should be understood that the operations at the first device 110 and the second device 120 should be coordinated. In other words, the second device 120 and the first device 110 should have a common understanding about configurations, parameters, etc. Such a common understanding can be achieved through any suitable interaction between the second device 120 and the first device 110 or the second device 120 and the first device 110 both apply the same rules / policies.

[0101] In the following, although some operations are described from the perspective of the first device 110, it is to be understood that the corresponding operations can be performed by the second device 120. Similarly, although some operations are described from the perspective of the second device 120, it is to be understood that the corresponding operations can be performed by the first device 110. For the sake of brevity, some identical or similar contents are omitted here.

[0102] exist Figure 2 In an example, the first device 110 may be a terminal device and the second device 120 may be a network device.

[0103] exist Figure 2 In some embodiments, the second device 120 may support operation in the NES mode. In some embodiments, the second device 120 may configure a CSI report configuration including a plurality of CSI report sub-configurations to the first device 110 via RRC signaling, wherein each sub-configuration may correspond to a spatial / power adaptation mode.

[0104] Hereinafter, the first part of the CSI report may be referred to as the non-omittable CSI part 1, and the second part of the CSI report may be referred to as the omittable CSI part 2.

[0105] In operation, the first device 110 receives 210 a CSI reporting configuration from the second device 120 , wherein the reporting configuration includes a first sub-configuration and a second sub-configuration.

[0106] In some example embodiments, the first subconfiguration is associated with a first priority reporting level and the second subconfiguration is associated with a second priority reporting level, and the second priority reporting level is lower than the first priority reporting level.

[0107] In some example embodiments, a first portion of the CSI corresponding to the first subconfiguration is associated with a first priority reporting level, and a second portion of the CSI corresponding to the first subconfiguration is associated with a second priority reporting level, and the second priority reporting level is lower than the first priority reporting level.

[0108] The first device 110 then sends 240 a CSI report associated with at least one of the first subconfiguration or the second subconfiguration to the second device 120 and based at least in part on the first and second first priority reporting levels.

[0109] In some example embodiments, the first sub-configuration may be associated with a first spatial or power adaptation mode, and the second sub-configuration may be associated with a second spatial or power adaptation mode different from the first spatial or power adaptation mode.

[0110] In some example embodiments, the CSI reporting configuration may be periodic CSI reporting, or MAC-CE based semi-persistent CSI reporting, and the CSI report may be carried on a physical uplink control channel (PUCCH).

[0111] How to generate the CSI report associated with the first sub-configuration and the second sub-configuration will be discussed below.

[0112] In some example embodiments, the first apparatus 110 may map 230 all CSI corresponding to the second subconfiguration to the second part of the CSI report (ie, CSI part 2).

[0113] In some example embodiments, first apparatus 110 may map 230 all CSI corresponding to the first subconfiguration to a first portion of a CSI report (i.e., CSI part 1). Alternatively, in some example embodiments, first apparatus 110 may map a first portion of the CSI corresponding to the first subconfiguration to a first portion of a CSI report, and map a second portion of the CSI corresponding to the first subconfiguration to a second portion of a CSI report, wherein the first portion of the CSI corresponds to a first set of report quantities, and the second portion of the CSI corresponds to a second set of report quantities.

[0114] In some example embodiments, the number of reports included in the first set of reported numbers or the second set of reported numbers is associated with one of:

[0115] Wideband Channel Quality Indicator (CQI);

[0116] Sub-band CQI,

[0117] Wideband precoding matrix indicator PMI,

[0118] Sub-band PMI,

[0119] CSI reference signal RS resource indicator CRI,

[0120] The layer indicator LI, or

[0121] Rank Indicator (RI).

[0122] In some example embodiments, the first device 110 may receive 220 from the second device 120 a UCI mapping configuration indicating at least one of the following:

[0123] at least one downgraded subconfiguration having the second priority reporting level, the at least one downgraded subconfiguration including the second subconfiguration, or

[0124] At least one UCI mapping rule, the at least one UCI mapping rule implying the at least one downgraded sub-configuration.

[0125] In summary, according to some embodiments of the present disclosure, the UCI mapping configuration may be explicitly / implicitly configured / indicated by the second device. The UCI mapping configuration may be associated with at least one of the following:

[0126] Which subframe configuration(s) are deprioritized,

[0127] which subframe configuration(s) are prioritized,

[0128] Which report quantity(s) were downgraded,

[0129] which report quantities are prioritized,

[0130] Which CSI subconfiguration reports are deprioritized, or Which CSI subconfiguration reports are prioritized.

[0131] In some example embodiments, the UCI mapping configuration may further indicate that different CSI subconfiguration reports corresponding to different subconfigurations having the same priority reporting level are mapped to the UCI bit sequence according to an ascending or descending order of the subconfiguration index.

[0132] It should be clarified that the UCI mapping configuration can also be defined as a default configuration. As an example, the UCI mapping configuration is predefined by a communication organization (such as 3GPP), or by a network operator or service provider. In this way, no additional signaling exchange is required.

[0133] Just to better understand the above process, refer to Figure 3A , Figure 3B and Figure 4 Some example embodiments are discussed.

[0134] In some example embodiments, it is proposed to differentiate UCI mapping for some CSI sub-configuration reports corresponding to some (spatial / power) adaptation modes configured via the CSI reporting configuration.

[0135] In some example embodiments, for periodic CSI reporting (or semi-persistent CSI reporting based on MAC CE), some of the adaptation modes may be prioritized by the second device 120 that implements UCI mapping to CSI part 1, and other adaptation modes may be left to be carried in CSI part 2. In this way, more capacity may be left for CSI part 1 that carries other existing CSI reports for other operations a.

[0136] In some example embodiments, the second device 120 may be able to (explicitly / implicitly) configure the first device 110 to have some CSI subconfigurations (or some CSI subconfiguration reports) corresponding to some of the (spatial / power) adaptation modes be deprioritized.

[0137] In some example embodiments, for a (spatial / power) adaptation mode that is not deprioritized, the corresponding CSI subconfiguration report may be mapped to CSI part 1 of the associated CSI report. Figure 3A , which shows an example structure 300A of CSI part 1. Figure 3A In the example, CSI subconfiguration #1, CSI subconfiguration #3 and CSI subconfiguration #5 are not downgraded.

[0138] In addition, in some example embodiments, based on the implementation requirements of the determined (SD / power domain) adaptation mode, the second device 120 can also accurately configure the first device 110, in which the reporting quantity needs to be captured in each of the CSI sub-configuration reports carried in the CSI part 1.

[0139] In some exemplary embodiments, wideband CQI information for the first TB of the sub-configuration in CSI Part 1 is sufficient for the gNB to implement determination and selection of the (SD / PD) adaptation mode. In this case, the sub-band differential CQI for the first TB may be less important or additional information with the second device 120 implementing determination and selection of the (SD / PD) adaptation mode, and it may be carried in CSI Part 2. In this way, more capacity may be left for CSI Part 1 to carry other existing CSI reports for other operational purposes.

[0140] In some exemplary embodiments, for UE mapping of CSI fields of adaptation modes that will not be deprioritized, they are mapped in the order of subconfiguration index, e.g., from lowest to highest, or vice versa. Figure 3A and Figure 3B , which shows an example structure 300A of CSI part 1 and an example structure 300B of CSI part 2. Figure 3A and 3B In , the CSI subconfiguration reports are mapped based on the order of the subconfiguration index, i.e., from lowest to highest.

[0141] As an example embodiment, there are a total of 6 subconfigurations for periodic CSI reporting, namely, subconfigurations #0 to #5. The second device 120 may (explicitly / implicitly) configure the first device 110 to prioritize the CSI reports of subconfigurations #0, #3, and #4 and the downgraded CSI reports of subconfigurations #1, #2, and #5 in increasing order of subconfiguration index. In this particular example embodiment, example CSI part 1 and CSI part 2 may be:

[0142] CSI part 1: wideband CQI for the first TB of subconfiguration #0; wideband CQI for the first TB of subconfiguration #3; wideband CQI for the first TB of subconfiguration #4;

[0143] CSI part 2: wideband CQI for the first TB of subconfiguration #1; wideband CQI for the first TB of subconfiguration #2; and wideband CQI for the first TB of subconfiguration #5.

[0144] In some example embodiments, for a (spatial / power) adaptation mode indicated as being deprioritized, the corresponding CSI subconfiguration report is mapped to CSI part 2 of the associated CSI report.

[0145] In some example embodiments, all report quantities associated with the deprioritized CSI subconfigurations are mapped to CSI part 2, i.e., following the conventional CSI field mapping order, and the remaining report quantities of the prioritized subconfigurations may be carried in CSI part 1.

[0146] How the UE generates CSI reports for subconfigurations mapped to different spatial and power adaptation modes will be discussed as follows.

[0147] In some example embodiments, for a sub-configuration indicated as being downgraded, the first device 110 may derive a UCI bit sequence separately, as indicated by the following formula.

[0148] A (1) =O ACK +O SR +O CSI-part1

[0149] A (2) =O CSI-part2 +A LP (1) +A LP (2)

[0150] A LP (1) =O LP CSI-part1

[0151] A LP (2) =O LP CSI-part2.

[0152] Among them, A (1) Refers to the bit sequence of CSI part 1, A (2) Refers to the bit sequence of CSI part 2, A LP (1)Refers to the low priority bit sequence corresponding to CSI part 1, A LP (2) Refers to the low priority bit sequence corresponding to CSI part 2. Further, O ACK refers to the bit position of ACK, O SR refers to the bit position of SR, o CSI-part1 Refers to the bit position of the CSI report corresponding to CSI part 1, o CSI -part2 Refers to the bit position of the CSI report corresponding to CSI part 1, o LP CSI-part1 Refers to the bit position of the CSI report with low priority corresponding to CSI part 1, o LP CSI-part2 Refers to the bit position of the CSI report with low priority corresponding to CSI part 2.

[0153] If the reporting quantity requires splitting the CSI into two parts, the first device 110 derives 2 low priority bit sequences while only considering the specific sub-configuration marked as being deprioritized, and otherwise derives a single bit sequence.

[0154] In some exemplary embodiments, these low priority UCI bits are then appended to the legacy CSI-Part 2 bit sequence to obtain the final A (2) sequence.

[0155] The above mapping does not affect the CSI reporting priority, and therefore does not affect any existing mode of CSI reporting with high priority, while allowing the network to also obtain CSI reporting of other modes that may facilitate fast adaptation.

[0156] As a specific embodiment, the second device 120 may transmit an RRC reconfiguration to the first device 110, wherein the RRC reconfiguration includes a CSI-report configuration, and the CSI-report configuration includes CSI reports of sub-configurations #1, #2, and #3. In this particular embodiment, sub-configurations #2 and #3 are deprioritized.

[0157] The first device 110 may measure CSI for all subconfigurations #1, #2, and #3. Then, the first device 110 reports subconfiguration #1 in a conventional manner and deprioritizes CSI subconfiguration reports for subconfigurations #2 and #3. The first device 110 generates a separate bit sequence and appends to the conventional sequence as a final CSI report. Next, a CSI report with a deprioritized pattern of UCI bits appended to the end of the report is sent to the second device 120.

[0158] Reference now Figure 4, which shows a flowchart of a method 400 implemented at a first device according to some example embodiments of the present disclosure.

[0159] At block 410 , the first device 110 receives an RRC reconfiguration with a subconfiguration for a different space / power mode.

[0160] At block 420, the first device 110 determines whether there are any sub-configurations that are deprioritized. If so, at block 430, the first device 110 derives low priority UCI bit sequences for CSI part 1 and CSI part 2 according to the conventional solution. At block 440, the first device 110 appends the low priority UCI bits to the conventional CSI part 2 bit sequence. If not, at block 440, the first device 110 derives the UCI bit sequence for CSI part 1 according to the conventional solution. At block 460, the first device 110 continues with UCI physical processing.

[0161] With the above processing, in the case of NES, although multiple sub-configurations are configured, since some sub-configurations can be lowered in priority, more transmission capacity can be left for carrying other existing CSI reports in CSI part 1.
