Method and device for supporting channel state information prediction of user equipment

Abstract

Methods and apparatus to support user equipment (UE) channel state information (CSI) prediction are disclosed. In case a CSI valid time (TCSI) occurs after a duration d after a CSI prediction reference time (Tref, CSI), a UE may receive configuration information for generating a predictive CS from a network, the predictive CS corresponding to the TCSI occurring after a CSI RS time (TRS) for a reference signal (RS) received at the UE for generating the predictive CSI. The UE may continue to generate the predictive CSI corresponding to the TCSI based on the measurement of the RS. The UE may then transmit the predictive CSI to the network at a CSI reporting time (T report). Mechanisms for selecting Tref, CSI are discussed. Mechanisms for use between the network and the UE for communicating to the UE one or more durations d corresponding to one or more CSI reports are discussed.

Description

Technical Field

[0001] The present application generally relates to wireless communication systems, including support for UE CSI prediction. Background Art

[0002] Wireless mobile communication technologies use various standards and protocols to transmit data between base stations and wireless communication devices. For example, wireless communication system standards and protocols may include the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) (e.g., 4G), 3GPP New Radio (NR) (e.g., 5G), and the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for wireless local area networks (WLANs) (commonly referred to within industry organizations as IEEE). ).

[0003] As envisioned by 3GPP, different wireless communication system standards and protocols may use various radio access networks (RANs) to facilitate communication between base stations of the RAN (which may also be often referred to as RAN nodes, network nodes, or simply nodes) and wireless communication devices called user equipment (UEs). 3GPP RANs may include, for example, Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and / or Next Generation Radio Access Network (NG-RAN).

[0004] Each RAN can use one or more radio access technologies (RATs) to perform communications between base stations and UEs. For example, GERAN implements GSM and / or EDGE RATs, UTRAN implements Universal Mobile Telecommunications System (UMTS) RATs or other 3GPP RATs, E-UTRAN implements LTE RATs (sometimes referred to herein as LTE), and NG-RAN implements NR RATs (sometimes referred to herein as 5G RATs, 5G NR RATs, or simply NR). In some deployments, E-UTRAN may also implement NR RATs. In some deployments, NG-RAN may also implement LTE RATs.

[0005] The base stations used by the RAN may correspond to the RAN. An example of an E-UTRAN base station is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (often also denoted as an evolved Node B, enhanced Node B, eNodeB, or eNB). An example of an NG-RAN base station is a Next Generation Node B (sometimes also referred to as a gNode B or gNB).

[0006] The RAN provides communication services with external entities through its connection to the Core Network (CN). For example, E-UTRAN may utilize the Evolved Packet Core (EPC), while NG-RAN may utilize the 5G Core Network (5GC). BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Various embodiments are described with respect to a UE. However, reference to a UE is provided for illustrative purposes only. The example embodiments may be used with any electronic component that can establish a connection with a network and is configured with hardware, software, and / or firmware for exchanging information and data with the network. Therefore, a UE as described herein is used to represent any suitable electronic component.

[0024] Figure 1Illustrated is a timeline 100 showing aspects related to transmission of a channel state information (CSI) report 102 based on a received reference signal (RS) 104, in accordance with embodiments herein. The CSI report 102 is an example of "CSI feedback" as referred to herein.

[0025] Figure 1 Various specific times that may be defined relative to the use of CSI feedback (eg, as may be defined in the specifications of a wireless communication system) are illustrated. The CSI RS time 106 may be denoted as T RS . T RS 106 may correspond to the end of the last RS used for CSI measurement. As illustrated, in some wireless communication systems, the RS considered may be a channel state information reference signal (CSI-RS) or synchronization signal block (SSB) received at the UE as transmitted by the network.

[0026] The CSI reporting time 108 may be represented as T 报告 . T 报告 108 may correspond to the start or end of a physical channel carrying the CSI report 102, such as a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0027] The CSI reference resource for RS110 can be expressed as T ref,RS . T ref,RS 110 may correspond to the latest time that RS 104 may arrive and still be used for CSI measurements corresponding to CSI report 102 (e.g., in order to meet the illustrated time for CSI report 102). ref,RS 110 is counted as the number of 报告 108 The number of backward symbols. In some such cases, when periodic or semi-persistent CSI is used, T ref,RS 110 to T 报告 108 is 4ms (for a single RS case) or 5ms (for multiple RS cases). In some such cases, when aperiodic CSI is used, T ref,RS 110 to T 报告 108 advance by Z′ symbols (eg, where Z′ may be a value defined in a specification of the wireless communication system; see, eg, 3GPP Technical Specification (TS) 38.214, Version 17.4.0, Sections 5.2.2.5 and 5.4 (December 2022)).

[0028] The CSI reference time defined based on downlink control information (DCI) can be expressed as T ref,DCI . T ref,DCI112 may correspond to the latest time that the DCI triggering the measurement of the RS 104 and / or the transmission of the corresponding CSI report 102 may arrive at the UE (e.g., in order to meet the illustrated time for the CSI report 102). ref,DCI 112 may be applicable with respect to / with respect to aperiodic CSI and may be counted as the number of times in time from T 报告 108 is the number of backward symbols. For aperiodic CSI, T 报告 108 can be located in T 报告 Z symbols before 108 (where Z may be a value defined in the specification of the wireless communication system; see, for example, 3GPP TS 38.214, Version 17.4.0, Section 5.4 (December 2022)).

[0029] It is possible that some wireless communication systems do not support CSI prediction behavior. For example, the UE may RS 106 to measure the CSI, and at another time (eg, T 报 In this case, the CSI report 102 indicates the CSI as in the past (at T RS 106 ) observed channel.

[0030] In this paper, due to the RS RS is received at UE at 106 until T 报告 The drift in the accuracy of the CSI in the CSI report 102 (from the network perspective) caused by the time gap in transmitting the CSI report 102 at T108 may be referred to as "CSI aging". Such CSI aging may be caused by the need to provide at least some CSI processing time within the period before sending the CSI report 102. However, due to this CSI aging, the CSI report 102 may be out of date (due to the CSI report 102 being out of date with respect to T108). RS 106).

[0031] Therefore, it may be beneficial to establish a framework for using UE-side CSI prediction, where the UE generates and then sends predictive CSI for the channel to the network. The predictive CSI may correspond to T RS 106 (e.g., to inform about the predicted state of the channel at that time). Therefore, it can be appreciated that such predictive CSI provides network information that, while predictive, is not as aged as CSI based strictly on measurements of RS 104.

[0032] It is contemplated that predictive CSI may be generated based on, for example, measurements of RS 104, optionally in combination with a CSI measurement history maintained at the UE. Additionally, UE speed and / or direction may be considered when generating predictive CSI. Other approaches / factor combinations are contemplated.

[0033] CSI prediction may be particularly useful in the case of high-speed UEs or medium-speed UEs, where the problem of CSI aging may be more pronounced due to the relatively rapid physical displacement of the UE relative to its serving cell (however, it is noted that cases of low or no speed of the UE may also beneficially use the mechanisms for predictive CSI as contemplated herein).

[0034] The proposal herein relates to the design and / or support of CSI prediction reference time definition and CSI prediction time configuration.

[0035] CSI prediction reference time definition

[0036] Figure 2 Illustrated is a timeline 200 showing various aspects related to the transmission of a CSI report 202 based on a received RS 204, in accordance with embodiments herein. The CSI report 202 is an example of "CSI feedback" as referred to herein.

[0037] With respect to the framework supporting CSI prediction, various specific times can be defined. Initially, it should be noted that T RS 206 and T 报告 208 It can be understood that these terms have been previously described herein (e.g., with respect to Figure 1 ).

[0038] In addition, the CSI valid time 210 can be expressed as T CSI . T CSI 210 may represent the time to which the CSI provided in the CSI report 202 is applicable. This means, for example, that without using predictive CSI, T CSI 210 equals T RS 206. However, in the predictive CSI implementation, since the predictive CSI corresponds to T RS 206 (for example, indicating the predicted CSI for that time), so it can be understood that T CSI 210 later than T RS 206 (such as Figure 2 exemplified).

[0039] In some embodiments, to support CSI prediction, the network may configure / indicate the T CSI 210. In some embodiments, TCSI 210 can predict the reference time 212 (which can be expressed as T) from the CSI ref,CSI ) variable duration d 214 of the measurement to configure / indicate, such as Figure 2 The duration d 214 can be configured / indicated according to the symbol. Figure 2 In FIG. 2 , duration d 214 is illustrated as a positive value, but negative values ​​of duration d are also contemplated for other embodiments.

[0040] Relative to T CSI 210 such network configuration / instruction (eg, based on the self-T ref,CSI 212 duration d214), it is envisaged that for T ref,CSI 212's following design.

[0041] In the first case, it is possible that T ref,CSI 212 is fixed (eg, in the specification of the wireless communication system). For example, T ref,CSI 212 can be set to T 报告 208(T ref,CSI =T 报告 ), which is the start or end of the physical channel (e.g., PUCCH or PUSCH) carrying the CSI report 202. ref,CSI 212 can be set to T ref,RS (See, e.g., Figure 1 T ref,RS 110)(T ref,CSI =T ref,RS ), which is the latest arrival time for RS204. For example, T ref,CSI 212 can be set to T RS 206(T ref,CSI =T RS ), which corresponds to the end of RS204. ref,CSI 212 can be set to T ref,DCI (See, e.g., Figure 1 T ref,DCI 112)(T ref,CSI =T ref,DCI ), which is the latest time for the DCI that triggers the CSI report 202.

[0042] Furthermore, with respect to these options in the first case, it is possible that the network can indicate to the UE which such option to use. This indication can reach the UE via any of radio resource control (RRC) signaling, medium access control element (MAC-CE), and / or DCI. It is contemplated that in some cases, the network can switch the UE back and forth between multiple of these options via subsequent such indications.

[0043] In the second case, it is possible that T ref,CSI 212 is the value configured by the network (for example, T ref,CSI 212). This information may be provided to the UE via any one of RRC signaling, MAC-CE, and / or DCI.

[0044] Note that although Figure 2 T is shown CSI 210 and T ref,CSI 212 is located after CSI report 202 in time, but this is not required. The effective predictive CSI under the illustrated framework is for RS T occurs anywhere after 206 CSI 210 (e.g., as described above). RS T occurs at any time after 206 CSI T caused by 210 ref,CSI Any placement of 212 will result in a valid predictive CSI arrangement.

[0045] CSI prediction time configuration

[0046] Relative to T CSI There are various applicable cases that should be considered for the configuration of the PUCCH. The first such case uses periodic CSI on the PUCCH. In this case, the periodic CSI is configured and / or released through RRC signaling. The second such case uses semi-persistent (SP) CSI on the PUCCH. In this case, the SP CSI is activated and / or deactivated by the MAC-CE. The third such case uses SP CSI on the PUSCH. In this case, the SP CSI is activated and / or deactivated by the DCI. The fourth such case uses aperiodic CSI on the PUSCH. In this case, the aperiodic CSI is triggered by the DCI.

[0047] Now let's discuss the ref,CSI Use to define T CSI The configuration / indication of the value of the duration d (e.g., as described herein (see Figure 2 and related descriptions)).

[0048] A first proposal for communicating the duration d to the UE relates to the case of periodic CSI reporting on PUCCH.

[0049] In a first option under the first proposal, it is possible that the duration d may be configurable by RRC signaling. Figure 3 An example of a CSI-ReportConfig IE 302 used as part of the RRC signaling according to the embodiments herein is illustrated, and the RRC signaling may contain a CSI-prediction value 304 indicating the duration d. Note that, if the CSI-prediction value 304 of the CSI-ReportConfig IE 302 is not configured, the UE may determine not to perform the CSI prediction method.

[0050] In a second option under the first proposal, the MAC-CE may be used to communicate one or more durations d to the UE. Figure 4 4 illustrates a MAC-CE 400 according to an embodiment of the present invention, which is communicated from T ref,CSI One or more durations d corresponding to one or more T for one or more predictive CSIs CSI The MAC-CE 400 may include a serving cell ID 402 and a bandwidth part (BWP) ID 404 that identify the applicable serving cell and bandwidth part, respectively.

[0051] Furthermore, the MAC-CE 400 may include one or more CSI reporting configuration ID fields 406 that identify the CSI-ReportConfigID of the corresponding CSI-ReportConfig object for activating CSI reporting at the UE.

[0052] Finally, the MAC-CE 400 may include one or more duration fields 408. Each duration field in the duration fields 408 indicates a duration d for a CSI-ReportConfig object identified by a corresponding one of the CSI report configuration ID fields 406 (wherein the CSI report configuration ID field 406 and the corresponding one of the duration fields 408 may share the same octet in the MAC-CE 400, as illustrated).

[0053] exist Figure 4In the illustrated example, the duration fields 408 each use two bits. Therefore, each duration field in the duration fields 408 can be configured with up to four different durations d (0, 1, 2, and 3) for its corresponding CSI-ReportConfig object.

[0054] In some embodiments, it is possible that a MAC-CE similar to the design just described includes only one CSI reporting configuration ID field in the CSI reporting configuration ID field 406 and a corresponding one duration field in the duration field 408. In such a system, it is possible that additional such MAC-CEs may be used to cause changes for additional / different CSI reporting configuration ID field / duration field pairs.

[0055] In other embodiments, the MAC-CE may have two or more such pairs (and note that the use of four such pairs in MAC-CE 400 is given by way of example and not limitation).

[0056] The second proposal for communicating the duration d to the UE relates to the case of SP CSI reporting on PUCCH (eg, as activated by MAC-CE).

[0057] In a first option under the second proposal, it is possible that the duration d may be configurable by RRC signaling. Figure 5 An example of a CSI-ReportConfig IE 502 used as part of the RRC signaling according to embodiments herein is illustrated, which may contain a semiPersistentOnPUCCH sequence 504 with a CSI-prediction value 506 (indicating a duration d). Note that in some such embodiments, if the CSI-prediction value 506 of the semiPersistentOnPUCCH sequence 504 of the CSI-ReportConfig IE 502 is not configured, the UE may determine not to perform the CSI prediction method.

[0058] In a second option under the second proposal, a MAC-CE activating SP CSI reporting on PUCCH may be used to communicate the duration d at the UE. Figure 6 1 illustrates a MAC-CE 600 according to an embodiment of the present invention, which is communicated from T ref,CSI One or more durations d corresponding to one or more T for one or more predictive CSIs CSI The MAC-CE 600 may be used according to the second proposal involving SP CSI reporting on the PUCCH.

[0059] Up to four SP CSIs can be configured. Therefore, the MAC-CE uses a four-bit bitmap 602 (including bits S3, S2, S1, and S0) to activate / deactivate the corresponding SP CSI. In addition, a new field can be introduced in the MAC-CE 600 for each activated SP CSI to configure the applicable duration d for that SP CSI.

[0060] For example, the duration field 604 (including fields d0, d1, d2, d3) provides an independent value for the duration d (e.g., according to the symbol) for each of the first, second, third, and / or fourth CSI-ReportConfig IEs of the configured SP CSI on the PUCCH (e.g., corresponding to the activated SP CSI in the SP CSI indicated in the bitmap 602).

[0061] In this example, due to the fact that each field uses four bits, there may be up to 16 different durations d (0, 1, 2, ..., 15) that can be configured for each CSI-ReportConfig.

[0062] In some embodiments, the MAC-CE 600 may include all four duration fields 604 regardless of the number of SP CSIs activated by the MAC-CE 600 (e.g., corresponding to the bitmap 602). In other embodiments, only the SP CSIs with CSI-ReportConfig activated on the PUCCH (e.g., via the bitmap 602) have corresponding duration fields 604 in the MAC-CE 600 (which may save signaling resources relative to the transmission of the MAC-CE 600).

[0063] A third proposal for communicating the duration d to the UE relates to the case of SP CSI reporting on PUSCH (eg, as activated by DCI).

[0064] In a first option under the third proposal, it is possible that the duration d may be configurable by RRC signaling. Figure 7AThe first possible case under the first option (using RRC signaling) is illustrated. In the first possible case, the CSI-ReportConfig IE 702 used as part of the RRC signaling may contain a semiPersistentOnPUSCH sequence 704 with a CSI-prediction value 706 (indicating a duration d). Note that in some such implementations, if the CSI-prediction value 706 of the semiPersistentOnPUSCH sequence 704 of the CSI-ReportConfig IE 702 is not configured, the UE may determine not to perform the CSI prediction method.

[0065] Figure 7B The second possible case under the first option (using RRC signaling) is illustrated. In the second possible case, the CSI-SemiPersistentOnPUSCH-TriggerState IE 708 is used as part of the RRC signaling and includes a CSI-prediction value 710 (indicating the duration d). Using the CSI-SemiPersistentOnPUSCH-TriggerState IE 708 (with, for example, using Figure 7A Conveying the CSI-prediction value 710 (as opposed to the semiPersistentOnPUSCH sequence 704 of the CSI-ReportConfig IE 702) may allow the network to set the duration d corresponding to the CSI-prediction value 710 on a trigger state granularity basis.

[0066] In the second option under the third proposal, MAC-CE may be used to communicate the duration d at the UE. The MAC-CE used in the second option of the third proposal may be similar to that of Figure 4 MAC-CE 400 is described.

[0067] In the third option under the third proposal, the duration d may be dynamically indicated by the DCI that activates SP CSI on the PUSCH. In some such cases, an existing field (e.g., the Time Domain Resource Allocation (TDRA) field) may be used to indicate the duration d. In some such cases, a new field may be introduced.

[0068] Under this third option, various cases may be considered. In a first case, the dynamic indication in the DCI of duration d may directly indicate the absolute number of symbols of duration d.

[0069] In the second case, the dynamic indication in the DCI can be given based on a table index. The UE can be configured with a corresponding table for various values ​​of duration d and can use the table index within the table to determine the specific duration d that applies. The table can be configured to the UE via RRC signaling or through MAC-CE and can be provided to the UE on a per-SP CSI reporting configuration basis.

[0070] A fourth proposal for communicating the duration d to the UE relates to the case of aperiodic CSI reporting on PUSCH (eg, as triggered by DCI).

[0071] In a first option under the fourth proposal, it is possible that the duration d may be configurable by RRC signaling. Figure 8A The first possible case under the first option (using RRC signaling) is illustrated. In the first possible case, the CSI-ReportConfig IE 802 used as part of the RRC signaling may contain an aperiodic sequence 804 with a CSI-prediction value 806 (indicating a duration d). Note that in some such implementations, if the CSI-prediction value 806 of the aperiodic sequence 804 of the CSI-ReportConfig IE 802 is not configured, the UE may determine not to perform the CSI prediction method.

[0072] Figure 8B The second possible case under the first option (using RRC signaling) is illustrated. In the second possible case, the CSI-AperiodicTriggerState IE 808 used as part of the RRC signaling includes a CSI-prediction value 810 (indicating the duration d). Using the CSI-AperiodicTriggerState IE 808 (with, for example, using Figure 8A Conveying the CSI-prediction value 810 using the aperiodic sequence 804 of the CSI-ReportConfig IE 802 (as opposed to the aperiodic sequence 804 of the CSI-ReportConfig IE 802) may allow the network to set the duration d corresponding to the CSI-prediction value 810 on a trigger state granularity basis.

[0073] Figure 8CThe third possible case under the first option (using RRC signaling) is illustrated. In the third possible case, the CSI-AssociatedReportConfigInfo IE 812 used as part of the RRC signaling includes a CSI-prediction value 814 (indicating the duration d). Using the CSI-AssociatedReportConfigInfo IE 812 (with, for example, using Figure 8A CSI-ReportConfig IE 802 or Figure 7B Conveying the CSI-prediction value 814 using the aperiodic sequence 804 of the CSI-AperiodicTriggerState IE 808 in the IE (as opposed to the aperiodic sequence 804 of the CSI-AperiodicTriggerState IE 808 in the IE) may allow the network to set the duration d corresponding to the CSI-prediction value 814 based on the associated reporting configuration granularity.

[0074] In the second option under the fourth proposal, MAC-CE may be used to communicate the duration d at the UE. The MAC-CE used in the second option of the fourth proposal may be similar to that of Figure 4 MAC-CE 400 is described.

[0075] In the third option under the fourth proposal, the duration d may be dynamically indicated by the DCI that activates aperiodic CSI on the PUSCH. In some such cases, an existing field (e.g., CSI request) may be used to indicate the duration d. In some such cases, a new field may be introduced.

[0076] Under this third option, various scenarios can be considered. In the first scenario, the dynamic indication in the DCI for duration d can directly indicate the absolute number of symbols for duration d. In the first sub-scenario, the indication of duration d in the DCI can be shared by all aperiodic CSI scheduled by the DCI. In the second sub-scenario, a separate indication of duration d can be provided in the DCI for a subset of all aperiodic CSI scheduled by the DCI and / or for each aperiodic CSI.

[0077] In the second case, the dynamic indication in the DCI can be given based on a table index. The UE can be configured with a corresponding table for various values ​​of duration d and can use the table index within the table to determine the specific duration d that applies. The table can be configured to the UE via RRC signaling or through MAC-CE and can be provided to the UE on a per-SP CSI reporting configuration basis.

[0112] Figure 11 An example architecture of a wireless communication system 1100 according to the embodiments disclosed herein is illustrated. The following description is provided for an example wireless communication system 1100 operating in conjunction with the LTE system standard and / or the 5G or NR system standard provided by the 3GPP technical specifications.

[0113] like Figure 11 As shown, wireless communication system 1100 includes UE 1102 and UE 1104 (although any number of UEs may be used). In this example, UE 1102 and UE 1104 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices capable of connecting to one or more cellular networks), but may also include any mobile or non-mobile computing device configured for wireless communication.

[0114] UE 1102 and UE 1104 may be configured to be communicatively coupled to RAN 1106. In an embodiment, RAN 1106 may be an NG-RAN, E-UTRAN, or the like. UE 1102 and UE 1104 utilize connections (or channels) (shown as connection 1108 and connection 1110, respectively) with RAN 1106, where each connection (or channel) includes a physical communication interface. RAN 1106 may include one or more base stations (such as base station 1112 and base station 1114) that implement connection 1108 and connection 1110.

[0115] In this example, connection 1108 and connection 1110 are the air interfaces that enable such communicative coupling and may conform to the RAT used by RAN 1106, such as, for example, LTE and / or NR.

[0116] In some embodiments, UE 1102 and UE 1104 may also directly exchange communication data via side link interface 1116. UE 1104 is shown as being configured to access an access point (shown as AP 1118) via connection 1120. By way of example, connection 1120 may include a local wireless connection, such as a connection compliant with any IEEE 802.11 protocol, wherein AP 1118 may include a local wireless connection. In this example, AP 1118 may not be connected to another network (eg, the Internet) through CN 1124.

[0117] In an embodiment, UE 1102 and UE 1104 may be configured to communicate with each other or with base station 1112 and / or base station 1114 over a multi-carrier communication channel using orthogonal frequency division multiplexing (OFDM) communication signals according to various communication techniques, such as, but not limited to, orthogonal frequency division multiple access (OFDMA) communication techniques (e.g., for downlink communication) or single-carrier frequency division multiple access (SC-FDMA) communication techniques (e.g., for uplink and ProSe or sidelink communication), although the scope of the embodiment is not limited in this respect. An OFDM signal may include multiple orthogonal subcarriers.

[0118] In some embodiments, all or part of base station 1112 or base station 1114 may be implemented as one or more software entities running on a server computer as part of a virtual network. Additionally, or in other embodiments, base station 1112 or base station 1114 may be configured to communicate with each other via interface 1122. In embodiments where wireless communication system 1100 is an LTE system (e.g., when CN 1124 is an EPC), interface 1122 may be an X2 interface. This X2 interface may be defined between two or more base stations (e.g., two or more eNBs, etc.) connected to an EPC and / or between two eNBs connected to an EPC. In embodiments where wireless communication system 1100 is an NR system (e.g., when CN 1124 is a 5GC), interface 1122 may be an Xn interface. This Xn interface is defined between two or more base stations (e.g., two or more gNBs, etc.) connected to a 5GC, between base station 1112 (e.g., a gNB) and an eNB connected to a 5GC, and / or between two eNBs connected to a 5GC (e.g., CN 1124).

[0119] The RAN 1106 is shown as being communicatively coupled to the CN 1124. The CN 1124 may include one or more network elements 1126 configured to provide various data and telecommunication services to customers / subscribers (e.g., UE 1102 and users of UE 1104) connected to the CN 1124 via the RAN 1106. The components of the CN 1124 may be implemented in one physical device or separate physical devices that include components for reading and executing instructions from a machine-readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium).

[0120] In an embodiment, CN 1124 may be an EPC, and RAN 1106 may be connected to CN 1124 via an S1 interface 1128. In an embodiment, S1 interface 1128 may be divided into two parts: an S1 user plane (S1-U) interface, which carries traffic data between base station 1112 or base station 1114 and a serving gateway (S-GW); and an S1-MME interface, which is a signaling interface between base station 1112 or base station 1114 and a mobility management entity (MME).

[0121] In an embodiment, CN 1124 may be a 5GC, and RAN 1106 may be connected to CN 1124 via an NG interface 1128. In an embodiment, NG interface 1128 may be divided into two parts: an NG user plane (NG-U) interface, which carries traffic data between base station 1112 or base station 1114 and a user plane function (UPF); and an S1 control plane (NG-C) interface, which is a signaling interface between base station 1112 or base station 1114 and an access and mobility management function (AMF).

[0122] Generally speaking, the application server 1130 may be an element that provides applications (e.g., packet-switched data services) that utilize Internet Protocol (IP) bearer resources with the CN 1124. The application server 1130 may also be configured to support one or more communication services (e.g., VoIP sessions, group communication sessions, etc.) for the UE 1102 and UE 1104 via the CN 1124. The application server 1130 may communicate with the CN 1124 via an IP communication interface 1132.

[0123] Figure 12 A system 1200 is illustrated for performing signaling 1234 between a wireless device 1202 and a network device 1218 according to embodiments disclosed herein. The system 1200 can be part of a wireless communication system as described herein. The wireless device 1202 can be, for example, a UE of the wireless communication system. The network device 1218 can be, for example, a base station (e.g., an eNB or gNB) of the wireless communication system.

The processor 1204 may include one or more baseband processors implemented using, for example, a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a controller, a field programmable gate array (FPGA) device, another hardware device, a firmware device, or any combination thereof, configured to perform the operations described herein.

[0126] The wireless device 1202 may include one or more transceivers 1210, which may include radio frequency (RF) transmitter and / or receiver circuitry that uses an antenna 1212 of the wireless device 1202 to facilitate signaling (e.g., signaling 1234) to and / or from the wireless device 1202 and other devices (e.g., network device 1218) according to a corresponding RAT.

[0127] The wireless device 1202 may include one or more antennas 1212 (e.g., one, two, four, or more). For embodiments with multiple antennas 1212, the wireless device 1202 may take advantage of the spatial diversity of these multiple antennas 1212 to transmit and / or receive multiple different data streams on the same time-frequency resources. This behavior may be referred to as, for example, multiple-input multiple-output (MIMO) behavior (referring to the multiple antennas used at each of the transmitting device and the receiving device to implement this aspect). MIMO transmissions by the wireless device 1202 may be implemented based on precoding (or digital beamforming) applied to the wireless device 1202, which multiplexes the data streams between the antennas 1212 based on known or assumed channel characteristics, such that each data stream is received with appropriate signal strength relative to the other streams and at a desired location in the spatial domain (e.g., the location of the receiver associated with the data stream). Certain embodiments may use single-user MIMO (SU-MIMO) methods (where data streams are all directed to a single receiver) and / or multi-user MIMO (MU-MIMO) methods (where separate data streams may be directed to separate (different) receivers in different locations in the spatial domain).

[0128] In certain embodiments with multiple antennas, the wireless device 1202 may implement analog beamforming techniques whereby the phases of the signals transmitted by the antennas 1212 are adjusted relative to each other so that the (joint) transmissions of the antennas 1212 can be directed (this is sometimes referred to as beam steering).

[0129] The wireless device 1202 may include one or more interfaces 1214. The interfaces 1214 may be used to provide input to or output from the wireless device 1202. For example, the wireless device 1202 (UE) may include interfaces 1214, such as a microphone, a speaker, a touch screen, and buttons, to allow a user of the UE to provide input to and / or output to the UE. Other interfaces of such a UE may be composed of transmitters, receivers, and other circuits (e.g., in addition to the transceiver 1210 / antenna 1212 already described) that allow communication between the UE and other devices, and may be based on known protocols (e.g., and etc.) to perform the operation.

[0130] The wireless device 1202 may include a predictive CSI module 1216. The predictive CSI module 1216 may be implemented via hardware, software, or a combination thereof. For example, the predictive CSI module 1216 may be implemented as a processor, circuitry, and / or instructions 1208 stored in the memory 1206 and executed by the processor 1204. In some examples, the predictive CSI module 1216 may be integrated within the processor 1204 and / or the transceiver 1210. For example, the predictive CSI module 1216 may be implemented by a combination of software components (e.g., executed by a DSP or general-purpose processor) and hardware components (e.g., logic gates and circuits) within the processor 1204 or the transceiver 1210.

[0131] The predictive CSI module 1216 may be used in various aspects of the present disclosure, for example, Figures 1 to 10 For example, the predictive CSI module 1216 can be configured to cause the wireless device 1202 to receive configuration for predictive CSI from the network device 1218 and / or to generate and send predictive CSI to the network device 1218 in the manner described herein.

[0132] The network device 1218 may include one or more processors 1220. The processor 1220 may execute instructions to perform various operations for the network device 1218, as described herein. The processor 1220 may include one or more baseband processors implemented using, for example, a CPU, a DSP, an ASIC, a controller, an FPGA device, another hardware device, a firmware device, or any combination thereof configured to perform the operations described herein.

[0133] The network device 1218 may include a memory 1222. The memory 1222 may be a non-transitory computer-readable storage medium that stores instructions 1224 (which may include, for example, instructions to be executed by the processor 1220). The instructions 1224 may also be referred to as program code or a computer program. The memory 1222 may also store data used by the processor 1220 and results calculated by the processor.

[0134] The network device 1218 may include one or more transceivers 1226, which may include RF transmitter and / or receiver circuitry that uses an antenna 1228 of the network device 1218 to facilitate signaling (e.g., signaling 1234) to and / or from the network device 1218 and other devices (e.g., wireless device 1202) according to a corresponding RAT.

[0135] The network device 1218 may include one or more antennas 1228 (e.g., one, two, four, or more). In embodiments with multiple antennas 1228, the network device 1218 may perform MIMO, digital beamforming, analog beamforming, beam steering, etc., as described.

[0136] The network device 1218 may include one or more interfaces 1230. The interfaces 1230 may be used to provide input to or output from the network device 1218. For example, the network device 1218 (base station) may include an interface 1230 consisting of a transmitter, a receiver, and other circuits (e.g., in addition to the transceiver 1226 / antenna 1228 already described) that enables the base station to communicate with other equipment in the core network and / or enables the base station to communicate with external networks, computers, databases, etc., for the purpose of operating, managing, and maintaining the base station or other equipment operatively connected to the base station.

[0137] The network device 1218 may include a predictive CSI module 1232. The predictive CSI module 1232 may be implemented via hardware, software, or a combination thereof.
