Description

Technical Field

[0001] The exemplary embodiments of this disclosure generally relate to communication systems, and more specifically to an improved beam reporting method for a beam management framework associated with a wireless communication network. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) fifth-generation (5G) technology is the next-generation wireless system and network architecture that can provide extreme broadband and ultra-robust low-latency connectivity. 5G technology improves the range of telecommunications services offered to end users and supports massive broadband communications that can provide gigabits per second of bandwidth for both uplink (UL) and downlink (DL) transmissions on demand. Beam reporting, associated with the measurement of reference and / or synchronization signals, is a key part of the beam management framework associated with 5G communication networks. Traditional 5G networks use beam reporting to align both DL beams (e.g., beams associated with transmissions generated by network elements such as gNBs) and UL beams (e.g., beams associated with transmissions generated by user equipment (UEs)). Therefore, improved beam reporting methods are desired for adaptively aligning data transmissions between network elements (e.g., gNBs) associated with corresponding network cells of the corresponding 5G (or higher) communication network and UEs (e.g., mobile computing devices).

[0074] Some embodiments of this disclosure will now be described more fully below with reference to the accompanying drawings, which illustrate some, but not all, of the embodiments of this disclosure. In fact, various embodiments of this disclosure may be embodied in many different forms and should not be construed as limited to the embodiments described herein; rather, these embodiments are provided so that the content of this disclosure will meet applicable legal requirements. The same reference numerals throughout refer to the same elements. As used herein, the terms “data,” “content,” “information,” and similar terms are used interchangeably to refer to data that can be transmitted, received, and / or stored according to embodiments of this disclosure. Therefore, the use of any such terms should not be construed as limiting the spirit and scope of the embodiments of this disclosure.

[0075] Furthermore, as used herein, the term "circuit system" refers to (a) a purely hardware circuit implementation (e.g., an implementation in an analog circuit system and / or a digital circuit system); (b) a combination of circuitry and (multiple) computer program products, including software and / or firmware instructions stored on one or more computer-readable storage media, which cooperate to cause a device to perform one or more functions described herein; and (c) a circuitry, such as (multiple) microprocessors or a portion thereof, which requires the software or firmware to function even if the software or firmware is not physically present. This definition of "circuit system" applies to all uses of the term herein, including in any claim. As another example, as used herein, the term "circuit system" also includes: an implementation comprising one or more processors and / or portions thereof, along with accompanying software and / or firmware. As defined herein, "computer-readable storage medium," referring to a physical storage medium (e.g., a volatile or non-volatile memory device), can be distinguished from "computer-readable transmission medium," referring to an electromagnetic signal.

[0076] The example communication systems, frameworks, and / or related technologies disclosed herein can be configured to provide an improved beam reporting method for adaptively aligning data transmission between network elements (e.g., gNBs) associated with a specific network cell of a particular communication system and user equipment (UEs) (e.g., mobile computing devices). However, it should be understood that this disclosure is not limited to the specific types of communication systems and / or processes disclosed. For example, although described in the context of a wireless cellular system utilizing 3GPP system elements (such as the 3GPP Next Generation Core Network), the disclosed embodiments are directly applicable to a variety of other types of communication systems. Furthermore, while this disclosure may describe certain embodiments in conjunction with 5G communication systems, other embodiments are also applicable to and include other networks and network technologies such as 3G, 4G, LTE, 6G, etc., but are not limited thereto.

[0077] According to illustrative embodiments implemented in a 5G communication system environment, one or more 3GPP standards, specifications, and / or protocols provide further explanation of the operations performed by the UE and core network elements / entities / functions and / or the UE and core network elements / entities or functions, such as 3GPP System Aspects (SA) Working Group 5 (3GPP SA5) and 3GPP RAN 3. Other 3GPP standards, specifications, and / or protocols provide additional conventional details that will be implemented by those skilled in the art. However, while exemplary embodiments are well-suited for implementations associated with the aforementioned 3GPP standards, alternative embodiments are not necessarily intended to be limited to any particular standard.

[0078] Embodiments of this disclosure generally relate to 5G / 6G New Radio (NR) latency and overhead reduction enhancements, and specifically to improved signal measurement (e.g., reference signal and / or synchronization signal measurements) and beam reporting methods for adaptively aligning data transmissions between network elements (e.g., gNBs) associated with a specific network cell of a particular 5G (e.g., or 6G and above) communication system and the UE. As described herein, signal measurement and beam reporting are key components of the beam management framework associated with 5G technology, which the network employs to align both downlink (DL) beams (e.g., beams associated with transmissions generated by network elements such as gNBs) and uplink (UL) beams (e.g., beams associated with transmissions generated by the UE).

[0079] In traditional telecommunications practice, beam reporting is a mechanism where a UE uses a received beam and / or multiple different received beams to measure the DL reference signal (RS) characterizing the beams of different network elements (e.g., gNB) to provide the measurement results to the network. The network and / or network elements (e.g., gNB) use measurements such as Layer 1 (L1) Reference Signal Received Power (RSRP) measurements for DL ​​and UL beam selection. In traditional NR communication systems, network elements (e.g., gNB) use the same L1-RSRP beam report for both DL and UL beam selection. In other words, in traditional NR communication systems, the network (e.g., via gNB) determines the UL beam(s) for the UE based on DL measurements. However, the L1-RSRP beam report based on DL beam measurements does not describe whether the same beam is feasible and / or strong enough for the UL direction. Furthermore, the L1-RSRP beam report does not describe whether the UE may have some constraints (e.g., how much power reduction the UE might need if a certain UL beam is used for transmission and / or if the UL beam is blocked).

[0080] To address these and other issues, embodiments of this disclosure provide methods configured to delegate at least a portion of beam selection responsibility to the UE (e.g., beam selection responsibility for UL beams). Therefore, according to various embodiments, the network (e.g., via gNB and / or Radio Resource Control (RRC)) can be configured to dynamically alter UE measurement and beam reporting behavior for DL ​​and UL beam selection—a technical capability not currently provided by conventional NR communication systems.

[0081] In various embodiments, L1 beam measurements for measuring and / or reporting UL and / or DL ​​beams and UE-associated beam reporting settings (e.g., settings related to physical beam measurements, reporting resource configuration, beam measurement type, beam reporting instance period, etc.) can be adaptively configured based on dynamic indications sent by network elements (e.g., gNBs). In this regard, one or more embodiments are configured to provide a method in which network elements (e.g., gNBs) can dynamically indicate beam reporting mode changes and / or beam measurement configurations to the corresponding UE. For example, in various embodiments, network elements (e.g., gNBs) can dynamically indicate beam reporting mode changes and / or beam measurement configurations to the corresponding UE via one or more Downlink Control Information (DCI) messages, one or more Radio Resource Control (RRC) messages, and / or one or more Media Access Control (MAC) Control Elements (MAC CEs).

[0082] In one or more embodiments, the beam reporting mode change is applied by the UE upon receiving a message triggering the beam reporting mode change (e.g., a DCI message and / or MAC CE) or upon confirmation of receiving such a message. Therefore, the UE can be dynamically configured, in part, based on the beam reporting mode change and / or beam measurement configuration, to perform one or more upcoming beam measurement and / or beam reporting instances until further indication and / or reconfiguration instructions are received from a network element (e.g., a gNB).

[0083] In this regard, in various embodiments, the beam measurement configuration sent by a network element (e.g., a gNB) may indicate at least one or more of one or more beam measurement types, one or more beam reporting modes, or beam reporting instance values ​​for configuring the UE. In various cases, the beam measurement configuration can be used to configure the UE for dynamic beam reporting to facilitate DL and / or UL beam selection. Furthermore, the beam measurement configuration can be used for hybrid DL and UL beam selection purposes.

[0084] In various embodiments, one or more beam measurement types indicated by the beam measurement configuration may include, but are not limited to, reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), and / or signal-to-noise ratio (SINR) correspondingly associated with one or more synchronization signals (SS) and / or channel state information (CSI) RS.

[0085] In one or more embodiments, the RRC and / or network elements (e.g., gNB) associated with the communication network can configure one or more beam reporting modes (e.g., mode 1, ..., mode ...) associated with the beam measurement configuration to the UE. N In some cases, the RRC may indicate a default beam reporting mode (e.g., mode 1) and / or one or more alternative beam reporting modes for configuring the corresponding UE (e.g., as part of the initial configuration when the UE connects to the corresponding communication network). As a non-limiting example, the first beam reporting mode (e.g., mode 1) of one or more beam reporting modes may be the default beam reporting mode associated with a report of a DL RS beam measurement set (e.g., the L1-RSRP measurement set of the corresponding DL RS). In some cases, a network element (e.g., a gNB) may determine from a beam report generated based on the default beam reporting mode (e.g., mode 1) that a particular DL beam associated with that DL RS set is favorable for DL ​​transmission, and further infer that that particular DL beam is also sufficient for UL reception.

[0086] As another non-limiting example, a second beam reporting mode (e.g., mode 2) in one or more beam reporting modes can be a beam reporting mode associated with a report of a set of UL beam measurements related to a set of UL beams. Thus, in this example, based on the second beam reporting mode (e.g., mode 2), the UE can be configured to consider only beams that are more suitable for UL transmission to a network element (e.g., gNB) to facilitate UL beam selection (e.g., and thus completely ignore consideration of DL beams). Alternatively or additionally, according to the second beam reporting mode (e.g., mode 2), the UE can determine that one or more UL beams associated with the set of UL beams being measured are adversely affected (e.g., interfered with), such that any necessary constraints (e.g., required power reduction as defined by, for example, 3GPP standards) make one or more UL beams unsuitable for adequate UL transmission, and the UE can report as much as possible to the network element (e.g., gNB).

[0087] As another non-limiting example, a third beam reporting mode (e.g., mode 3) in one or more beam reporting modes can be a hybrid beam reporting mode associated with the DL beam measurement set and UL beam measurement set of the respective reported DL and UL beam sets. Furthermore, network elements (e.g., RRC and / or gNB) can indicate a predetermined number of beams in a specific beam set that the UE should report. For example, in various cases, the third beam reporting mode (e.g., mode 3) can be associated with a predetermined number of beams (e.g., two beams) in each respective beam set that the UE must report. Therefore, network elements (e.g., gNB) can use two DL beam reports and UL beam reports to facilitate beam selection.

[0088] As another non-limiting example, a fourth beam reporting mode (e.g., mode 4) in one or more beam reporting modes can be a beam reporting mode associated with both a DL and / or UL beam measurement set that reports the DL and / or UL beam set accordingly, and associated with one or more network elements (e.g., gNBs) configured for multiple transmit receiver points (mTRP) communication. Thus, the UE can be configured to generate a beam report associated with that DL and / or UL beam measurement set and send it to one or more corresponding network elements (e.g., one or more gNBs) configured for mTRP communication.

[0089] In various embodiments, one or more beam reporting modes indicated by network elements (e.g., via corresponding DCI messages) may be associated with the same reporting resource configuration. For example, in some embodiments, a first beam reporting mode (e.g., mode 1) and a second beam reporting mode (e.g., mode 2) may be associated with the same reporting resource configuration, such that one or more beam reports generated based on the first beam reporting mode and / or the second beam reporting mode (e.g., correspondingly mode 1 and / or mode 2) are transmitted according to the same reporting resource configuration. Additionally or alternatively, in various embodiments, a specific reporting resource configuration may be specific to a particular beam reporting mode among one or more beam reporting modes.

[0090] In various embodiments, the reporting resource configuration may include, but is not limited to, reporting period, reporting format, beam report size, and / or one or more network resources. As a non-limiting example, a UE configured according to a first beam reporting mode (e.g., mode 1) can currently be configured based on the first reporting resource configuration, and a recently received message (e.g., a DCI message and / or MAC CE) can trigger the UE to be reconfigured partially based on an alternative beam reporting mode associated with the same reporting resource configuration (e.g., the first reporting resource configuration). Therefore, any subsequent beam reports generated by the UE based on an alternative beam reporting mode (e.g., mode 2) will be sent based on the same reporting resource configuration.

[0091] In various embodiments, the reporting resource configuration may refer to a configuration associated with at least one or more of the following: reporting period, time resources, frequency resources, reporting format (e.g., PUCCH or PUSCH format), and / or reporting parameters (e.g., the number of reporting resources and / or resource indicators to be included in the beam report). When one or more beam reporting modes are associated with the same reporting resource configuration, the reporting resource configuration may include one or more of the following: reporting period, time resources, frequency resources, reporting format (e.g., PUCCH or PUSCH format), and / or reporting parameters (e.g., the number of reporting resources and / or resource indicators to be included in the beam report). In various examples, a resource indicator may refer to a value that indicates and / or points to a resource index.

[0092] For example, when reporting the SSB index value X When performing beam measurements, the SSB resource indicator SSBRI= can be used. Y To refer to the SSB index value = XIn another example, SSB index value = 2 can be referred to as SSBRI = 0, SSB index value = 4 can be referred to as SSBRI = 1, and so on. SSBRI values ​​(e.g., or similarly, CSRI values) can be determined based on the order in which the SSB / CSI-RS index values ​​are listed in the measurement resource configuration (e.g., the first resource in the list has a first RI value = 0, the second resource has a second RI value = 1, and so on). A similar mapping can be made to resource indicators for CSI-RS configured for beam reporting.

[0093] In one or more embodiments, the reporting resource configuration for dynamic beam reporting can be configured by an RRC associated with the communication network (e.g., a 5G network). In various embodiments, one or more beam reporting modes can be associated with the same reporting resource configuration. Additionally or alternatively, in various embodiments, one or more beam reporting modes can be associated with correspondingly independently configured reporting resource configurations. Furthermore, in various embodiments, one or more beam reporting modes can be associated with the same set of measurement resources. For example, a UE can be configured to use the same set of measurement resources when configured with one or more beam reporting modes associated with the same set of measurement resources.

[0094] Furthermore, in various embodiments, the RRC can define an explicit association between the reporting resource configuration and a predetermined set of measurement resources associated with one or more DL and / or UL measurement resources (e.g., DL RS / SSB or CSI-RS). If no explicit association is configured between the reporting resource configuration and the predetermined set of measurement resources, upon receiving a trigger indication (e.g., a corresponding DCI and / or MAC CE message indicating a change in beam reporting mode), the corresponding UE should assume that the UE will use the measurement resources associated with the DL RS configuration (e.g., non-zero power (NZP) CSI-RS and / or SSB configured for any purpose (e.g., beam management, time-frequency tracking, CSI capture, etc.)) to generate a beam report. Additionally or alternatively, in various embodiments, one or more beam reporting modes may be associated with a corresponding predetermined set of measurement resources.

[0095] In one or more embodiments, when the UE is configured for dynamic beam reporting (e.g., configured to employ one or more beam reporting modes), the UE may also be configured to indicate to a network element (e.g., a gNB) that the UE needs and / or prefers to generate and / or send beam reports according to at least one alternative beam reporting mode (e.g., a beam reporting mode other than the default beam reporting mode) among one or more beam reporting modes indicated by the network element. Therefore, in various cases, the UE may send a request to the network element (e.g., a gNB) to change the current beam reporting mode associated with the UE, wherein the request indicates the UE's preferred and / or desired beam reporting mode.

[0096] In one embodiment, the UE can be configured to trigger a scheduling request (SR) transmission when a preferred alternative beam reporting mode is determined. Alternatively, in various other embodiments, a random access channel (RACH) procedure (e.g., contention-based random access (CBRA) and / or contention-free random access (CFRA) procedure) can be triggered. An indication describing the UE's preferred alternative beam reporting mode can be associated with the configuration of the CFRA preamble. In one example, the UE indication can be provided in the MAC CE via UL shared channel (UL-SCH) resources, or as part of the RACH procedure (e.g., in msgA / msg3).

[0097] When a UE instructs a network element (e.g., a gNB) that it needs and / or prefers to generate and / or transmit beam reports according to at least one alternative beam reporting mode, the UE can be configured to expect the network to change the reporting mode within a predefined time period (e.g., within a predetermined number of reporting periods). If the UE does not receive an indication of beam reporting mode change associated with the requested beam reporting mode (e.g., via a subsequently received DCI message), the UE can retransmit the indication (e.g., a request) to the network element.

[0098] In one or more examples, the UE may (e.g., via SR, RACH procedure, and / or MAC CE) indicate a preference for a specific beam reporting mode (e.g., a preference for mode 2). For example, in some cases, the UE may indicate (e.g., request) a specific beam reporting mode based on one or more configuration implementations associated with the UE (e.g., device configuration, device capabilities, device components, etc.).

[0099] In some cases, a UE may determine, for example, to request a change in beam reporting mode due to a Maximum Probability Exposure (MPE) event. An MPE event can be an event in which the UE has determined that power backoff has been applied (or can be applied) due to power management configurations associated with the UE. In one example, power backoff can be associated with the serving cell as specified in 3GPP specifications TS 38.101-1, TS 38.101-2, and TS 38.101-3. c (For example, P-MPR) c This relates to the reduction of the maximum allowed UE output power. In other words, the UE may need to reduce the maximum power of one or more UL transmissions on one or more uplink resources configured for UL transmissions (e.g., by performing power backoff).

[0100] In some cases, the conditions for a UE to indicate (e.g., request) a change in beam reporting mode can be determined based on a signal quality threshold. For example, if the UE determines that at least one DL RS of at least one measurement resource set associated with at least one beam reporting mode is higher than a signal quality threshold based on a signal quality threshold configured by the network (and / or a signal quality threshold otherwise provided in a communication specification (e.g., a 3GPP specification) associated with the network), the UE can indicate (e.g., request) a change in beam reporting mode.

[0101] Alternatively or concurrently, the signal quality-based conditions used to determine the change in beam reporting mode may include determining and / or indicating that the quality of at least one DL RS is higher than that of one or more DL RSs corresponding to the current usage TCI state associated with the UE's DL reception and / or UL transmission, and / or associated with a better offset value. In various embodiments, the offset value may be -3dB, 0, 3dB, etc., and may be configurable by RRC.

[0102] Alternatively or concurrently, the signal quality-based conditions used to determine the change in beam reporting mode may include determining and / or indicating that the signal quality of at least one DLRS is higher than that of at least one DLRS corresponding to the measurement resource set for beam reporting currently measured by the UE and / or associated with a better offset value. Furthermore, in various embodiments, the UE may determine that the signal quality of at least one DLRS is higher than that of the first DLRS corresponding to the measurement resource set for beam reporting currently measured by the UE. N Highest DL RS.

[0103] In various embodiments, the signal quality threshold can be configured by the network using RRC signaling. Furthermore, in various examples, the DL RS measured by the UE to determine whether to trigger an indication of a beam reporting mode change can be associated with at least one of the UE's DL reception, UL transmission, or both DL reception and UL transmission.

[0104] In some cases, the UE may generate and / or send a request to switch to a preferred beam reporting mode in response to the detection of a more advantageous and / or alternative UL beam for reporting. For example, the UE may determine that the currently used UL beam (e.g., from the beam set used by the UE for reporting DL RSRP) is more suitable than the currently used UL beam. In various embodiments, the UE may send the request to switch to the preferred beam reporting mode to network elements via dedicated UL resources. Additionally or alternatively, the UE may indicate the preferred beam reporting mode via bit fields and / or information fields associated with a network-defined beam report (e.g., a default beam report) (e.g., via bit fields detailing one or more other L1 measurements, such as rank, CSI, etc., within the L1-RSRP report or the default beam report).

[0105] As described herein, in one or more embodiments, RRC and / or network elements (e.g., gNB) may send one or more of the following to the UE via corresponding indications (e.g., indications associated with corresponding DCI messages, RRC messages, and / or MAC CE): beam reporting mode change and / or beam measurement configuration indication. In various cases, one or more beam measurement types, one or more beam reporting modes, and / or beam reporting instance values ​​of the beam measurement configuration may be associated with corresponding DCI code point values ​​indicated via corresponding DCI bit fields of the corresponding DCI message. For example, each of one or more beam reporting modes may be mapped to a specific DCI code point value. Furthermore, network elements (e.g., gNB) may encode one or more corresponding DCI bit fields of the DCI message to indicate to the UE the reported resource configuration.

[0106] As a non-limiting example, the first DCI code point value associated with the corresponding DCI bit field may indicate the default beam reporting mode (e.g., DCI code point value 0 may indicate beam reporting mode 1). As another non-limiting example, the second DCI code point value associated with the corresponding DCI bit field may indicate an alternative beam reporting mode (e.g., DCI code point value 1 may indicate beam reporting mode 2). In various embodiments, the DCI format associated with the corresponding DCI message may be any current DCI format (e.g., the DCI format specified according to the current 3GPP standard) or any predefined new DCI format.

[0107] In one or more embodiments, if the UE determines that a bit field associated with the corresponding DCI message indicates a change in beam reporting mode, the UE can be configured to perform beam measurement and / or beam reporting for at least one of the following based on the corresponding beam reporting mode: (i) the next scheduling report instance, (ii) for N The predetermined beam reports instance values ​​(e.g., where the value) N (associated with the value of the beam reporting instance configured by RRC, MAC CE and / or indicated by DCI message), or (iii) if N If not configured, the default beam reporting instance value will be used (e.g., a fixed value for 1 beam reporting instance).

[0108] For example, in various embodiments, the indication of beam measurement configuration sent to the UE (e.g., a DCI message sent via RRC, MAC CE, and / or gNB) may be associated with beam reporting instance values. N (For example, N =2) is associated with this value, which specifies the number of beam measurement and / or beam reporting instances that the UE should perform (e.g., the number of beam measurements to be performed and the number of corresponding beam reports to be generated based on the beam measurements). Therefore, in some examples, the beam reporting instance value... N This can refer to the number of reporting opportunities that the UE expects to provide beam reports to network elements (e.g., gNB).

[0109] In some embodiments, the beam reporting mode indicated by the network may be associated with a request to obtain a reduced number of measurement samples. In some examples, a reduced number of measurement samples may refer to a measurement for obtaining a single measurement or measurement sample for at least one DL RS in a measurement resource set associated with the corresponding beam reporting mode. Upon receiving an indication of a beam reporting mode with a reduced number of measurement samples, the UE may obtain beam measurements for subsequent reporting instances, wherein the beam measurements described in detail in the corresponding beam report are based on a single measurement sample.

[0110] Alternatively, in some embodiments, the UE may be instructed to obtain beam measurements for subsequent reported instances, wherein the beam measurements described in detail in the corresponding beam report are based on L 1 sample, of which L This is configured by RRC and / or specified in other ways (e.g., in one or more 3GPP specifications). In some examples, a request for a reduced number of measurement samples can be configured as part of the beam reporting mode, or can be explicitly indicated in a message that indicates a change in the beam reporting mode (e.g., DCI message, MAC CE, etc.).

[0111] In some embodiments, the UE can be configured (e.g., via DCI messages sent by RRC, MAC CE, and / or gNB) to persist a specific beam reporting mode until the UE receives an indication of activation of one or more Transport Configuration Indicator (TCI) states from a network element (e.g., gNB). For example, in various cases, the UE can be configured to perform beam measurement and / or beam reporting according to a corresponding beam reporting mode until at least one of the following is achieved: (i) receiving a TCI state activation (or indication), (ii) receiving a TCI state activation (or indication) for UL transmission and / or DL ​​reception, or (iii) receiving at least one TCI state activation (or indication) for a reporting target channel associated with UL transmission and / or DL ​​reception. In various embodiments, when the UE is configured to perform beam measurement and / or beam reporting according to one beam reporting mode, the UE is not required to report according to other beam reporting modes on the same beam reporting instance.

[0112] In one example, the TCI may include one or more reference signals (e.g., one or more DL RSs) that provide quasi-co-location information. The UE can use the quasi-co-location information to determine which one or more DL RSs are used as references for DL ​​reception, UL transmission, or both DL reception and UL transmission. In various embodiments, TCI state activation is provided to the UE by the network. The activation of one or more TCI states provides the UE with a TCI state that the network can use for beam indication. Beam indication refers to a configuration where the UE is configured to apply the indicated TCI state to DL reception, UL transmission, or both DL reception and UL transmission. In various embodiments, if only one TCI state is active, the active TCI is also the indicated TCI state.

[0113] In one or more embodiments, one or more beam reports generated by the UE based on one or more corresponding beam reporting modes can be generated based on the same beam reporting format. In other words, in various cases, even if network elements have indicated a change in the beam reporting mode (e.g., via DCI messages), the beam reporting format associated with the UE can remain unchanged. As a non-limiting example, a default beam reporting mode (e.g., mode 1) can configure the UE to report the SSB-RI+RSRP values ​​of the DL-RS set for DL ​​reception, while an alternative beam reporting mode (e.g., mode 2) can configure the UE to report the SSB-RI+RSRP values ​​of the DL-RS set for UL transmission.

[0114] Figure 1The illustration depicts a communication system 100 configured according to at least some embodiments of the present disclosure. However, it should be understood that the embodiments are not limited to the network configurations shown herein or described below. It should be understood that the elements shown in the communication system 100 are intended to represent the main functions provided within the system. Therefore, Figure 1 The box references shown represent specific elements in a 5G network that provide the main functions. However, other network elements can be used to implement some or all of the main functions represented. Furthermore, it should be understood that... Figure 1 Not all the functions of a 5G network are described. Instead, functions that help explain the illustrative embodiments are shown.

[0115] For example, communication system 100 can be deployed within a radio access architecture. However, the system can be deployed in other applications, including in other communication networks, such as Advanced LTE (LTE-A), Universal Mobile Telecommunications System (UMTS) Radio Access Network (UTRAN or E-UTRAN), Wireless Local Area Network (WLAN or Wi-Fi), Global Microwave Access Interoperability (WiMAX), Bluetooth®, Personal Communication Services (PCS), ZigBee®, Wideband Code Division Multiple Access (WCDMA), systems using Ultra Wideband (UWB) technology, sensor networks, Mobile Ad Hoc Networks (MANET), and Internet Protocol Multimedia Subsystem (IMS), or any combination thereof. Any access network (AN) qualified to access the 5G core network can be used instead of NG RAN / gNB, such as untrusted non-3GPP access terminated at a non-3GPP Interoperability Function (N3IWF), trusted non-3GPP access terminated at a trusted non-3GPP Gateway Function (TNGF), or wired access terminated at a Radio Access Gateway Function (W-AGF). Furthermore, although described herein in conjunction with a 5G core network, the methods, apparatus, and computer program products of certain example embodiments may be used in conjunction with other technologies, such as 6G networks.

[0116] One or more UE 102a-n devices can be configured to establish radio connections with radio access network (RAN) nodes (such as gNBs) on one or more communication channels within a cell. The physical link from UE 102a to the gNB is called an uplink or reverse link, while the physical link from the gNB to UE 102a is called a downlink or forward link. It should be understood that the gNB or its functionality can be implemented using any node, host, server, or access point (AP) or other entity suitable for this purpose. Furthermore, one or more UE 102a-n devices can be configured to establish radio connections with one or more other UE 102a-n devices, for example, via a sidechain channel.

[0117] A communication system typically includes multiple gNBs, which may also be configured to communicate with each other via wired or wireless links designed for this purpose. These links can be used for signaling purposes. A gNB is a computing device configured to control the radio resources of the communication system to which it is coupled. A gNB may also be referred to as a base station, access point, or any other type of interface device, including relay stations capable of operating in a wireless environment. A gNB includes or is coupled to one or more transceivers. From the gNB's transceivers, a connection is provided to an antenna element that establishes a bidirectional radio link to the UE. Therefore, the gNB's transceivers and the UE's transceivers may include transmitters and receivers configured to communicate via a channel. Although gNBs are referred to herein, this is only an example and not a limitation, as other types of AN nodes may also be employed.

[0118] Therefore, as shown in the figure, the communication system 100 includes one or more UEs 102a-n, which communicate with AN node 104, such as via an air interface. In some embodiments, AN node 104 is a RAN node. One or more UEs 102a-n may be mobile stations, and such mobile stations may include, for example, mobile phones, computers, or any other type of communication device. Therefore, the terms “user equipment (UE),” “user equipment,” “computing device,” or “apparatus” as used herein should be interpreted broadly to cover various types of mobile stations, subscriber stations, or more generally, communication devices, including examples such as combinations of data cards inserted into a laptop or other device.

[0119] One or more UEs 102a-n can also refer to portable computing devices, including wireless mobile communication devices operating with or without a subscriber identification module (SIM), including but not limited to the following types of devices: mobile station (mobile phone), smartphone, personal digital assistant (PDA), mobile phone, device using a wireless modem (alarm or measuring device, etc.), laptop and / or touchscreen computer, tablet, game console, laptop, and multimedia device. It should be understood that UE 102a can also be a virtually exclusive uplink-only device, an example of which is a camera or camcorder that loads images or video clips onto a network. UE 102a can also be a device capable of operating in an IoT network, in which case objects can transmit data over the network without human-to-human or human-to-computer interaction. UE 102a (or in some embodiments, a Layer 3 relay node) is configured to perform one or more user equipment functions. UE 102a can also be referred to as a subscriber unit, mobile station, remote terminal, access terminal, user terminal, or user equipment, to name just a few.

[0120] In one embodiment, one or more UEs 102a-n consist of a Universal Integrated Circuit Card (UICC) and a Mobile Equipment (ME). The UICC is the user-related part of the UE and contains at least one Universal Subscriber Identity Module (USIM) and appropriate application software. The USIM securely stores the International Mobile Subscriber Identity (IMSI) number and its associated key, which is used to identify and authenticate subscribers accessing the network. The ME is the user-independent part of the UE and contains Terminal Equipment (TE) functionality and various Mobile Terminal (MT) functions.

[0121] AN node 104 is illustratively part of the RAN of communication system 100. In a 5GS network, AN node 104 is typically implemented by a gNB. Such an access network may include, for example, multiple base stations, which may include one or more gNBs (which may also be divided into centralized unit (CU) and distributed unit (DU) portions) and / or other AN node types, such as evolved Node B (eNB), Node B, base station (BS) and / or N3IWF, or any other type of access node, such as a WLAN access point, and one or more associated radio network control functions. The base station and radio network control functions may be logically separate entities, but in a given embodiment, they may be implemented in the same physical network element, such as a base station router or a femtocellular access point. As those skilled in the art will understand, any kind of AN node and / or access node may implement similar operations, functions, etc.

[0122] In some example embodiments, AN node 104 is operatively coupled to core network function 106, such as via an NG interface. Core network function 106 may include Access and Mobility Management Function (AMF), Session Management Function (SMF), Representative Network Function (NF-X), or any other core network function. Core network function 106 may be an element in the core network (CN) portion of the communication system 100 responsible for one or more related operations.

[0123] 5G supports the use of multiple-input multiple-output (MIMO) antennas, more base stations or nodes than LTE (the so-called small cell concept), including macro sites operating in cooperation with smaller sites, and employs a variety of radio technologies depending on service requirements, use cases, and / or available spectrum. 5G mobile communications support a wide range of use cases and related applications, including video streaming, augmented reality, different data sharing methods, and various forms of machine-type applications such as (massive) machine-type communications (mMTC), including vehicle safety, various sensors, and real-time control. 5G has multiple radio interfaces, such as cmWave below 6 GHz or mmWave above 24 GHz, and can be integrated with existing legacy radio access technologies such as LTE. Integration with LTE can be implemented as a single system where macro coverage is provided by LTE, and 5G radio interface access originates from small cells via aggregation to LTE. In other words, 5G can support inter-RAT interoperability (such as LTE-5G) and inter-RI interoperability (inter-radio interface interoperability, such as below 6 GHz-cmWave, 6 or above 24 GHz-cmWave, and mmWave).

[0124] Low-latency applications and services in 5G require bringing content closer to the wireless, leading to local breakthroughs and multi-access edge computing (MEC). 5G enables data sources to perform analytics and knowledge generation. This approach requires leveraging resources that may not have continuous network connectivity, such as laptops, smartphones, tablets, and sensors. MEC provides a distributed computing environment for hosting applications and services. It also enables the storage and processing of content near cellular subscribers for faster response times. Edge computing can encompass a wide range of technologies, such as wireless sensor networks, mobile data acquisition, mobile signature analytics, collaborative distributed peer-to-peer self-organizing networks and processing (which can also be categorized as local cloud / fog computing and grid / mesh computing), dew computing, mobile edge computing, cloudlets, distributed data storage and retrieval, autonomous self-healing networks, remote cloud services, augmented and virtual reality, data caching, the Internet of Things (IoT) (massive connectivity and / or time-critical), and critical communications (autonomous vehicles, traffic safety, real-time analytics, time-critical control, healthcare applications, etc.).

[0125] Figure 2 The figure illustrates an example of device 200, which can be configured to function as a network entity, or can be embodied by a network entity such as UE 102a, AN node 104, AMF, SMF, and / or NF-X. Figure 2 As shown, device 200 includes, or is associated with or communicates with, a processing circuitry system 202, a communication interface 204, and / or a memory device 206. The processing circuitry system 202 may communicate with the memory device 206 via a bus for transferring information between components of device 200.

[0126] In some embodiments, device 200 may be embodied in various computing devices as described above. However, in some embodiments, the device may be embodied as a chip or chipset. In other words, the device may include one or more physical packages (e.g., chips), including materials, components, and / or wires on structural components (e.g., substrates). The structural components may provide physical strength, dimensional conservation, and / or electrical interaction constraints for the component circuitry systems included thereon. Thus, in some cases, the device may be configured to implement an embodiment on a single chip or as a single "system-on-a-chip." Thus, in some cases, a chip or chipset may constitute components for performing one or more operations to provide the functionality described herein.

[0127] The processing circuitry system 202 can be embodied in a variety of different ways. For example, the processing circuitry system 202 can be embodied as one or more of various hardware processing components, such as a coprocessor, microprocessor, controller, digital signal processor (DSP), processing element with or without a DSP, or various other circuitry systems including integrated circuits, such as ASICs (Application-Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), microcontroller units (MCUs), hardware accelerators, application-specific computer chips, etc. Therefore, in some embodiments, the processing circuitry system may include one or more processing cores configured to execute independently. A multi-core processing circuitry system can implement multiprocessing within a single physical package. Additionally or alternatively, the processing circuitry system may include one or more processors configured in series via a bus to implement independent execution of instructions, pipelines, and / or multiple threads.

[0128] In one example embodiment, the processing circuitry 202 may be configured to execute instructions stored in the memory device 206 or instructions otherwise accessible by the processing circuitry 202. Alternatively or additionally, the processing circuitry may be configured to perform hard-coded functions. Thus, whether configured by hardware or software methods, or by a combination thereof, the processing circuitry may represent an entity (e.g., physically embodied in a circuitry) capable of performing operations according to embodiments of the present disclosure when configured accordingly. Thus, for example, when the processing circuitry is embodied as an ASIC, FPGA, etc., the processing circuitry may be hardware specifically configured to perform the operations described herein. Alternatively, as another example, when the processing circuitry 202 is embodied as an executor of instructions, the instructions may specifically configure the processor to perform the algorithms and / or operations described herein when the instructions are executed. However, in some cases, the processing circuitry 202 may be a processor of a particular device (e.g., an image or video processing system) configured to further configure the processing circuitry to employ embodiments of the present disclosure by instructions that perform the algorithms and / or operations described herein. The processing circuit system 202 may include a clock, an arithmetic logic unit (ALU), and logic gates configured to support the operation of the processing circuit system.

[0129] Communication interface 204 can be any device, such as a device or circuit system implemented in hardware or a combination of hardware and software, configured to receive and / or send data to a network and / or any other device (e.g., specific UE 102a, UE, etc.) or module communicating with it. In this regard, communication interface 204 may include, for example, an antenna (or multiple antennas) and supporting hardware and / or software for enabling communication with a wireless communication network. Furthermore, communication interface 204 may embody and / or integrate one or more RF and / or wireless transceivers, each of which includes a transmitter for transmitting signals and a receiver for receiving signals. The one or more RF and / or wireless transceivers may be configured to facilitate communication over 4G / LTE networks, 5G networks, etc.

[0130] Furthermore, one or more RF and / or wireless transceivers can be configured to facilitate communication on various corresponding communication networks. One or more RF and / or wireless transceivers receive signals or data and / or transmit signals and / or data. In various embodiments, the processing circuitry 202 can control (multiple) antennas and / or one or more RF and / or wireless transceivers to receive, transmit, broadcast, or send signals and / or data. Additionally or alternatively, the communication interface 204 may include circuitry for interacting with (multiple) antennas and / or one or more RF and / or wireless transceivers to transmit signals via the antennas or process the reception of signals received via the antennas. Additionally or alternatively, in some environments, the communication interface 204 may support wired communication. Therefore, for example, the communication interface may include a communication modem and / or other hardware / software for supporting communication via cable, digital subscriber line (DSL), universal serial bus (USB), or other mechanisms.

[0131] Memory device 206 may be non-transitory and may include, for example, one or more volatile and / or non-volatile memories. In other words, for example, memory device 206 may be an electronic storage device (e.g., a computer-readable storage medium) that includes gates configured to store data (e.g., bits) that can be retrieved by a machine (e.g., a computing device, such as a processing circuitry system). Memory device 206 may be configured to store information, data, content, applications, instructions, etc., so that the device can perform various functions according to exemplary embodiments of this disclosure. For example, memory device 206 may be configured to buffer input data for processing by processing circuitry system 202. Additionally or alternatively, memory device 206 may be configured to store instructions executed by processing circuitry system 202.

[0132] Figure 3 The illustration shows a data flow diagram associated with an improved beam reporting method 300 for a communication network according to one or more exemplary embodiments of the present disclosure. Various operations of method 300 can be implemented, for example, by one or more components of device 200. In various embodiments, device 200 may be embodied by a network element (e.g., AN node 104). In various other embodiments, device 200 may be embodied by UE 102a. Additionally or alternatively, device 200 may be embodied by any other specific computing device associated with a particular communication network (e.g., a smartphone, laptop, tablet, network device, etc.). It should be understood that device 200 can be configured to perform method 300 with reference to components of device 200, which are again provided as examples and not as limitations. Thus, device 200 includes components configured to perform various operations associated with method 300, such as processing circuitry 202, at least one processor, communication interface 204, at least one memory device 206, etc.

[0133] Method 300 begins with operation 302, in which the device 200 associated with AN node 104 is configured to send a default beam measurement configuration to UE 102a. As described herein, network elements (e.g., AN node 104) can dynamically indicate (e.g., based on RRC messages, MAC CE, and / or one or more DCI messages) the default beam measurement configuration to the corresponding UE 102a. Therefore, UE 102a can be dynamically configured, in part, based on the default beam measurement configuration, to perform one or more upcoming beam measurement and / or beam reporting instances.

[0134] In various embodiments, the default beam measurement configuration indicated by a network element (e.g., a gNB) may indicate at least one or more of one or more beam measurement types, one or more beam reporting modes, or beam reporting instance values ​​for configuring UE 102a. As described herein, a network element (e.g., AN node 104) or, in some cases, the RRC may provide a default beam measurement configuration to indicate that a default beam reporting mode (e.g., mode 1) will be used to configure UE 102a.

[0135] At operation 304, the apparatus 200 associated with UE 102a is configured to perform beam measurements based on a default beam reporting mode associated with a default beam measurement configuration. In various embodiments, the default beam reporting mode (e.g., mode 1) may be a beam reporting mode associated with reporting DL RS beam measurement sets (e.g., synchronization signal and physical broadcast channel (PBCH) block (SSB) L1-RSRP measurement sets for DL ​​reception). Therefore, UE 102a may generate a first beam report at least partially based on the default beam reporting mode (e.g., mode 1).

[0136] At operation 306, the device 200 associated with UE 102a is configured to send a first beam report (e.g., a beam report associated with SSB L1-RSRP measurements for DL ​​reception) to AN node 104. As described herein, UE 102a may be configured to send one or more beam reports, at least in part, based on a specific reporting resource configuration. In various embodiments, the specific reporting resource configuration may include, but is not limited to, reporting period, reporting format, beam report size, and / or one or more network resources. Furthermore, in various embodiments, the specific reporting resource configuration may be specific to a corresponding beam reporting mode (e.g., a default beam reporting mode, such as mode 1) among one or more beam reporting modes indicated by a network element (e.g., AN node 104). UE 102a may send the first beam report via the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH) associated with AN node 104.

[0137] At operation 308, the device 200 associated with AN node 104 is configured to determine the need for a change in beam reporting associated with UE 102a. For example, AN node 104 may determine, at least in part, based on a first beam report received from UE 102a, one or more measurements that may need to be associated with at least one alternative beam reporting mode to facilitate the selection of at least one of a preferred beam associated with UL transmission and / or a preferred beam associated with DL reception. Alternatively, in other cases, AN node 104 may receive a request from UE 102a to initiate a switch of the current beam reporting mode associated with UE 102a.

[0138] At operation 310, the device 200 associated with AN node 104 is configured to indicate a beam reporting mode change to UE 102a. As described herein, AN node 104 may be configured to send to the corresponding UE 102a an indication of a beam reporting mode change and / or beam measurement configuration associated with at least one of one or more alternative beam reporting modes (e.g., alternatives to the default beam reporting mode). Non-limiting examples of alternative beam reporting modes (e.g., modes 2-4) may include, but are not limited to, at least one of the following: (i) an alternative beam reporting mode associated with reporting a UL beam measurement set associated with a UL beam set, (ii) an alternative (e.g., hybrid) beam reporting mode associated with both a DL beam measurement set and a UL beam measurement set correspondingly reported with the DL and / or UL beam sets, or (iii) an alternative beam reporting mode associated with a DL and / or UL beam measurement set correspondingly reported with the DL and / or UL beam sets associated with one or more network elements (e.g., AN node 104) configured for mTRP communication.

[0139] Furthermore, as described herein, in addition to the change in beam reporting mode, AN node 104 can also indicate the associated beam measurement configuration to UE 102a. The beam measurement configuration can be related to the beam reporting instance value. N (For example, N =2) is associated with the number of beam measurements and / or beam reporting instances that UE 102a should perform (e.g., the number of beam measurements performed and the number of corresponding beam reports generated based on the beam measurements).

[0140] At operation 312, the apparatus 200 associated with UE 102a is configured to switch the current beam reporting mode (e.g., the current default beam reporting (e.g., mode 1)) to an alternative beam reporting mode (e.g., mode 2) based at least in part on a beam reporting mode change and / or beam measurement configuration indicated by a network element (e.g., gNB). UE 102a can then perform one or more beam measurements at least in part based on the alternative beam reporting mode (e.g., mode 2) and / or beam measurement configuration to generate one or more corresponding beam reports.

[0141] For example, UE 102a can be configured to perform one or more SSB L1-RSRP measurements for UL transmission on the beam set associated with UE 102a. Furthermore, in Figure 3 In the example method 300 shown, the beam measurement configuration (e.g., as shown in operation 310) associated with the beam reporting mode change and the beam reporting instance value are given. N =2 is associated. Therefore, UE102a can report instance values ​​based on beam (e.g., N =2) Perform two SSB L1-RSRP measurements on the UL transmission and generate a second beam report and a third beam report accordingly.

[0142] At operation 314, device 200 associated with UE 102a is configured to send a second beam report (e.g., with beam reporting instance value) to AN node 104 associated with SSB L1-RSRP measurements for UL transmission. N =1 associated beam report). UE 102a can send a second beam report at least in part based on the same reporting resource configuration associated with the default beam reporting mode (e.g., mode 1) and used to send the first beam report. Furthermore, UE 102a can send the second beam report via the PUCCH or PUSCH associated with AN node 104.

[0143] At operation 316, device 200 associated with UE 102a is configured to send a third beam report (e.g., with beam reporting instance value) to AN node 104 associated with SSB L1-RSRP measurements used for UL transmission. N =2 associated beam reports). UE 102a can send a third beam report at least in part based on the same reporting resource configuration associated with the default beam reporting mode (e.g., mode 1) and used to send the first beam report. In addition, UE 102a can send the third beam report via the PUCCH or PUSCH associated with AN node 104.

[0144] At operation 318, the device 200 associated with UE 102a is configured to revert to the default beam reporting mode (e.g., mode 1) and continue to perform beam measurements (e.g., SSB L1-RSRP measurements for DL ​​reception) based on the default beam reporting mode associated with the default beam measurement configuration. Therefore, UE 102a can generate a fourth beam report at least partially based on the default beam reporting mode (e.g., mode 1).

[0145] At operation 320, the device 200 associated with UE 102a is configured to send a fourth beam report at least in part based on the reporting resource configuration associated with the default beam reporting mode (e.g., mode 1). Furthermore, UE 102a may send the fourth beam report via the PUCCH or PUSCH associated with AN node 104.
