The system (200) may include components and elements configured to support known or conventional operational features that do not need to be described in detail herein. In one exemplary embodiment, the system (200) may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment (100) of FIG. 1 as described above.

[0029] The system (200) generally includes a base station (202) (hereinafter referred to as "BS (202)") and a user equipment device (204) (hereinafter referred to as "UE (204)").

The memory modules (216, 234) may also be integrated into their respective processor modules (210, 230). In some embodiments, the memory modules (216, 234) may each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by the processor modules (210, 230).

[0037] 2. System and method for performing detection information auxiliary beam management

[0038] Presented herein are systems and methods for sensing information-assisted beam management in large-scale beam architectures. The approaches described in detail herein can accelerate beam training and tracking procedures, save RS overhead, and improve link robustness under narrow beams. First, a new definition of sensing information may be specified to represent or describe actual and / or virtual anchor(s), line-of-sight (LOS) and non-line-of-sight (NLOS) path(s), physical reflector(s), and / or gNB / UE location(s). Subsequently, this sensing information may be associated with beam management to support the corresponding procedures. Finally, a mechanism may be considered in which living and death procedures related to physical / spatial / communication paths can be predicted based on sensing information (e.g., virtual anchors), and subsequently, the NW / UE can provide advance notice regarding predicted quality of service (QoS) changes. For example, some related event(s) can be reported in advance before a beam link failure occurs.

[0039] In 5G new radio (NR), analog beam-forming may be introduced into mobile communication to ensure the robustness of high-frequency communication. For downlink (DL) transmission, quasi-co location (QCL) states (also referred to as transmission configuration indicator (TCI) states or beam states) may be used to support beam indication for the DL control channel (e.g., physical downlink control channel (PDCCH)), DL data channel (e.g., physical downlink sharing channel (PDSCH)), and channel-state-information reference signaling (CSI-RS), among other things.

[0040] Likewise, in the case of uplink (UL) transmission, spatial relationship information (corresponding upper layer parameters are also spatialRelationInfoA (which may be referred to as) can be used to support beam indication for UL control channels (e.g., physical uplink control channel (PUCCH)) and sounding reference signals (SRS). In addition, beam indication for UL data channels (e.g., physical uplink shared channel (PUSCH)) can be achieved through mapping with one or more SRS resources. SRS resources can be indicated by the gNB and ports of the UL data channels. Beam configuration for the UL data channels can be derived accordingly from spatial relationship information associated with the SRS resources or ports. Then, an integrated TCI framework may be introduced, and based on the framework, a single TCI state may be applied to both DL signaling (e.g., PDSCH, PDCCH, and CSI-RS) and UL signaling (e.g., PUSCH, PUCCH, and SRS) or to either of these to determine the corresponding transmit and receiver (Tx / Rx) beam(s).

[0041] While various approaches under 5G NR with flexible configurations are applicable to different scenarios, RS overhead can increase rapidly with the increase in candidate beams introduced by large antenna elements and panels on both the gNB and UE sides. Meanwhile, link robustness can be severely degraded due to a lack of spatial diversity with narrower pairs of Tx and Rx beams. For example, when the number of gNB antenna elements increases from 8x4 to 32x32, the number of candidate Tx beams to be probed in beam training can increase from 32 to 1024, and the effective beam width for the horizontal and vertical domains can decrease from 22.5 degrees to 5.625 degrees and from 45 degrees to 5.625 degrees, respectively. Consequently, the corresponding RS overhead required to support beam training can increase significantly.

[0042] To utilize narrow beam pair(s) and save RS overhead for subsequent data transmission while maintaining sufficient beamforming gain, beam management procedures can be improved accordingly. In a sensing radio environment, a significant amount of information regarding gNB / UE locations, reflectors, and obstacles can be acquired in advance to perform sensing-assisted beam management. The following issues can be addressed.

[0043] First, the definition of sensing information can be considered. Specifically, to generalize this sensing information rather than on a case-by-case basis, it can be effectively identified which types of sensing parameters play a significant role in describing wireless channel quality. For example, definitions of real and virtual anchor(s) can be introduced to describe LOS / NLOS paths, such as to describe the location and range of available Tx beams corresponding to the anchors, respectively.

[0044] Second, a framework for associating sensing information with beam management can be reconsidered to accelerate beam alignment or beam tracking. Subsequently, an association mechanism between sensing information, beam measurement, reporting, and display can be considered, and a corresponding signaling design can be developed accordingly.

[0045] Third, a mechanism may be considered in which life-death procedures related to physical paths (in contrast to virtual paths extending from virtual anchors) can be predicted based on sensing information (e.g., virtual anchors), and subsequently, the NW / UE can provide advance notification regarding predicted QoS changes. For example, some relevant events may be notified to the gNB side in advance before an actual beam link failure occurs.

[0046] I. Context regarding beamforming management

[0047] Now, referring to FIG. 3, a block diagram of an environment (300) for beam-based uplink (UL) and downlink (DL) transmissions is illustrated. In this illustration, full solid lines may represent selected Tx / Rx beams for communication. As a trade-off for wide or ultra-wide spectrum resources, significant propagation loss introduced by extremely high frequencies can be a notable challenge. To address this, antenna arrays and beamforming training techniques using large-scale MIMO (e.g., up to 1024 antenna elements per node) may be used to achieve beam alignment and obtain sufficiently high antenna gain. To maintain low implementation costs while still benefiting from antenna arrays, analog phase shifters may be very attractive for implementing mmWave beamforming. As such, the number of controllable phases may be finite, and constant modulus constraints may be applied to these antenna elements. Given pre-specified beam patterns, variable phase shift-based BF training targets can generally identify the best pattern for subsequent data transmission in a single transmission / reception point (TRP) and a single panel case.

[0048] For context, "beam state" may be equivalent to a Quasi-Common Location (QCL) state, Transmission Configuration Indicator (TCI) state, spatial relationship (also referred to as spatial relationship information), reference signal (RS), spatial filter, or pre-coding. Additionally, "beam state" may also be referred to as "beam."

"Beam ID" is equivalent to a QCL state index, TCI state index, spatial relationship state index, reference signal index, spatial filter index, or pre-coding index. A spatial filter may be a UE-side or gNB-side spatial filter, and a spatial filter may also be referred to as a spatial domain filter.

[0049] Additionally, "spatial relationship information" may consist of one or more reference signals (RS).

Additionally, RS may include, among other things, a DL reference signal and UL reference signaling. DL RS may include CSI-RS, SSB, and DMRS (e.g., DL DMRS). UL RS may include, among other things, SRS, DMRS (e.g., UL DMRS), and PRACH. "UL signal" may include PUCCH, PUSCH, or SRS. "DL signal" may include PDCCH, PDSCH, or CSI-RS.

A "beam group" may be one in which different Tx beams within a single group can be received or transmitted simultaneously, or Tx beams between different groups may not be received or transmitted simultaneously. Additionally, a "beam group" may be described from the perspective of a UE.

[0053] An "antenna group" may include / represent or correspond to different Tx beams within a single group that may not be received or transmitted simultaneously, or Tx beams between different groups that may be received or transmitted simultaneously. Additionally, an "antenna group" may include more than N different Tx beams within a single group that may not be received or transmitted simultaneously, or fewer than N different Tx beams within a single group that may be received or transmitted simultaneously, where N is a positive integer. An "antenna group" may correspond to Tx beams between different groups that may be received or transmitted simultaneously. An "antenna group" is described from the perspective of a UE. An antenna group may be equivalent to an antenna port group, a panel, or a UE panel. Additionally, antenna group switching may correspond to panel switching.

[0054] "Group information" may include, represent, or correspond to, among other things, "information grouping one or more reference signals," "resource sets," "panels," "sub-arrays," "antenna groups," "antenna port groups," "groups of antenna ports," "beam groups," "transmit entities / units," or "receive entities / units."

[0055] An anchor includes a virtual anchor or a physical anchor. Additionally, "anchor" may be equivalent to a transmission point, a reception point, a site, a reference signal (RS), a spatial filter, or a precoding, among other things. UL power control parameters may include at least one of a target power (also referred to as P0), a path loss RS (also referred to as coupling loss RS), a scaling factor for the path loss (also referred to as alpha), and a closed-loop process. CSI may include at least one of a reference signal receive power (RSRP), a signal to noise and interference ratio (SINR), a receive signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), and a precoding matrix indicator (PMI).

[0056] II. Setting Transmission Parameters to Represent Detected Information

[0057] Under given scenarios (e.g., in a living room or in a dense city), radio ray tracing (radio path maps) can be widely used to describe radio channels. However, for communication, the benefits of ray tracing technology based on real-time radio path maps for the UE may be unclear due to cost. Alternatively, LOS paths, which can be well emulated based on the locations of the UE and TRP, may be considered. However, the variety and multiplexing gains contributed by NLOS paths may be lost. Therefore, a trade-off between accuracy and complexity for representing the radio environment may be considered.

[0058] Now, referring to FIG. 4, a block diagram of a system (400) for a virtual anchor that assists beam management is shown. A definition of a virtual anchor for balancing / solving the above problems is introduced as a key modality / point of sensing information. A real or physical anchor may point to a gNB / TRP, and then the virtual anchor may point to a virtual object corresponding to a first-order or higher-order reflection associated with the real / physical anchor.

[0059] In the case of millimeter-wave communication, path loss due to diffraction and scattering can be much greater than in normal reflections. Considering the dominant recovery power, the emulation accuracy of the physical channel may be slightly degraded, but LOS and first (and sometimes second) reflection paths can be considered for wireless transmission.

[0060] Consequently, a virtual anchor (VA) corresponding to a regular reflection can be introduced for beam management. Specifically, according to reflector theory, the virtual anchor can have its own position and a range of available angle of departure (AoD). To emulate the physical channel much more accurately, considering that the reflector may not be smooth, the virtual anchor can be assumed / represented as a region or a cluster of sub-anchors rather than a single anchor (e.g., rather than a point source).

[0061] Based on advanced technologies (such as pre-measurement, positioning, or artificial intelligence (AI)), UEs, TRPs (e.g., actual anchors referred to as sites), and VA locations can be determined in advance or estimated in advance. VA-related information (e.g., location, range of available AoDs), and additional information related to sub-VAs (e.g., distribution area in terms of location or angle domain, number of sub-VAs) can be used to perform beam refinement and tracking procedures.

[0062] Beam refinement and tracing procedures can be accelerated, particularly for NLOS paths and large-scale multiple input, multiple output, reconfigurable intelligence surfaces (MIMO / RIS). For example, multiple paths can be identified for different pairs of UE panels and TRPs (e.g., group-based reporting).

[0063] Life-death procedures related to the physical path of a link (e.g., procedures triggered by connected / active states or disconnected / off / inactive states) can be estimated and predicted. Mechanisms enabling NW / UE can provide advance notification to interested consumers regarding predicted QoS changes or predicted beam / TRP changes. This enables the adjustment of application behavior before the path's life-death procedures take effect. This can have applications in specific automotive use cases, such as remote and autonomous driving.

[0064] Compared to emulating a wireless path map based on ray tracing technology, the UE complexity for emulating an NLOS path based on VA can be significantly reduced. Considering some estimation errors due to (VA-related) methods, some additional real-world field tests (e.g., some neighboring beams) may be used along with NLOS path estimation, as in beam refinement / tracing.

[0065] The TRP may be virtualized as a VA to assist UE beam determination. The UE may receive configuration signaling (e.g., from a gNB / BS) that includes transmission parameter settings to indicate sensing information (e.g., VA (location) and range of the reflector). The transmission parameter settings may include at least one of the following: among others, location information, range of available angles, and size information. Additionally, the location information may include the location of the site or VA (e.g., center location) and the location of the reflector or obstacle / fault (along a potential wireless transmission path). Additionally, the size information may include at least one of a radius and a length (e.g., in a horizontal or vertical domain, or in 2D or 3D). Additionally, the size information may include size information of the site or VA (e.g., center location) and the reflector or obstacle / fault. Additionally, the available angles may include available angles of the site or VA. Additionally, the angles may include at least one of the angle of arrival (AoA) or the angle of departure (AoD). AoA may include at least one of the arrival azimuth and the arrival zenith. AoD may include at least one of the departure azimuth and the departure zenith.

[0066] There may be multiple virtual cells for a given cell due to a reflector (e.g., a reconfigurable intelligent surface (RIS)). The VA can be defined by a center position and a range (e.g., having a radius of 20 cm). For example, the range of the reflector may correspond to a physical channel without any obstacles that can be defined from the perspective of the VA (e.g., the available AOD range).

[0067] The transmission parameter setting may include a plurality of sub-VA or site-related information. Each of the sub-VA / site-related information may include, among other things, at least one of location information, a range of available angles, and size information. In some embodiments, the transmission parameter setting may include diffusion information. The diffusion information may correspond, among other things, to location information or angle (e.g., location diffusion or angle diffusion).

[0068] Angle-corresponding diffusion information may correspond to angle diffusion. In some embodiments, angle-corresponding diffusion information may include, among others, arrival azimuth diffusion, arrival zenith diffusion, departure azimuth diffusion, and departure zenith diffusion. Additionally, configuration signaling may include, among others, SIB, MIB, MAC-CE, or RRC signaling.

[0069] III. Beam measurement configuration to enable sensing information-assisted beam management.

[0070] To enable detection information auxiliary beam management, one or more transmission parameter settings for representing detection information may be associated with various modes.

[0071] In some embodiments, one or more transmission parameter settings may be associated with an RS. The RS may include, among other things, an RS port, an RS port group, an RS resource, a set of RS resources, and an RS resource setting. In some embodiments, the RS may include SSBs or CSI-RSs, and the transmission parameter setting may be associated with a group of SSBs and CSI-RSs. In some embodiments, the RS may include a CSI-RS, and the transmission parameter setting may be associated with a set of CSI-RS resources or included in a set of CSI-RS resources. In this case, one or more RS resources within the set may be associated with a transmission parameter setting (e.g., a VA). The UE may determine course beam alignment based on the location of the VA and its own location. Based on course information, the UE may probe a channel corresponding to a set of CSI-RSs. In some embodiments, a single RS may be associated with multiple transmission parameter settings, which means that multiple candidate physical paths (e.g., LOS or NLOS through the VA) may be considered.

[0072] In some embodiments, the transmission parameter settings may be associated with or included in the beam state or group information. When the RS is configured with beam state or group information, the configuration may indicate that the transmission parameter settings can be used for coarse Tx / Rx beam determination. For example, the beam state may be dynamically displayed or enabled. Consequently, RS measurements may be dynamically switched based on different transmission parameter settings.

[0073] In some embodiments, the transmission parameter setting may be associated with TRP-related information. Additionally, the TRP-related information may include a CORESET pool ID and an RS resource set or setting ID. In some embodiments, the transmission parameter setting may be associated with a reporting configuration. Additionally, the reporting configuration may be associated with the transmission parameter setting. The corresponding measurement(s) may be based on the transmission parameter setting (e.g., based on a VA or reflector). In some embodiments, the transmission parameter setting may be associated with a bandwidth part (BWP) or a component carrier (CC). In some embodiments, the transmission parameter setting may be associated with a UL power control parameter.

[0074] Now, referring to FIG. 5, a block diagram of a system (500) for configuring beam management by associating with transmission parameter settings is shown. In some embodiments, a transmission parameter setting may be associated with an uplink (UL) power control parameter (e.g., path loss RS). Additionally, a transmission parameter setting may be selected from a pool of transmission parameter settings (e.g., configured by RRC signaling). The association may be indicated by other RRC, MAC-CE, or DCI signaling (e.g., from gNB / BS to UE). In some embodiments, one or more transmission parameter settings may be associated with, among others, beam states, group information, TRP-related information, reporting configuration, component carrier (CC), bandwidth part (BWP), or UL power control parameter. If RS is configured for or is configured for at least one of beam states, group information, TRP-related information, reporting configuration, CC, BWP, or UL power control parameter, one or more corresponding transmission parameter settings may be applied to RS.

[0075] IV. Beam state related configuration with detection information.

[0076] In these embodiments, the beam state can be used to determine the spatial domain filter on the UE side. Meanwhile, the sensing information may be related to how the UE assists in accelerating beam refinement and measurement. By associating the beam state with one or more transmission parameter settings, the transmission parameter settings can be dynamically applied to RS or beam measurement, or to subsequent data transmission. Additionally, a pool of transmission parameter settings can be pre-configured by RRC signaling, while a pool of beam state(s) can be pre-configured through RRC signaling.

[0077] Then, through MAC-CE signaling, a TCI state may be activated and associated with one or more transmission parameter settings. When multiple transmission parameter settings are provided, one or more sites or VAs may serve the UE. It may be useful for the UE to perform beam refinement and determine the life-or-death procedure as discussed in Section V. In some embodiments, in MAC-CE, multiple beam states may be associated with code points, and one or more transmission parameter settings may be associated with multiple beam states. The multiple beam states may include several groups, such as a first group of beam states to be applied to DL signals and a second group of beam states to be applied to UL signals. Each of one or more transmission parameter settings may be associated with one of the several groups.

[0078] Finally, via the DCI command, a single beam state (e.g., a TCI code point) can be indicated and applied to both DL and UL signaling, or either one. For example, if a single TCI state applied to a DL or UL signal may include multiple transmission parameter settings, the UE can determine which transmission parameter settings are valid due to the fact that some VAs may be blocked or out of their effective range. Thus, the UE can properly refine or adjust its Rx / Tx beams.

[0079] Now, referring to FIG. 6, a block diagram of a system (600) for a beam state-related configuration having sensing information is shown. As shown, first, by RRC signaling from gNB / BS, the UE can be individually configured or reconfigured with beam / TCI state(s) and transmission parameter setting(s) (Stage 1). One of the TCI states may include one or more QCL state(s). Then, through MAC-CE signaling, the UE can be enabled or disabled with one or more TCI state(s) and transmission parameter setting(s) (Stage 2). The mapping between the transmission parameter setting(s) and the beam state can be determined by MAC-CE. Finally, one of the enabled beam states is indicated by DCI and can be applied to both DL and UL signals (Stage 3).

[0080] V. Event reporting on life and death procedures of beams and physical links

[0081] Beam failure recovery and wireless link monitoring can be based on RS measurements. More specifically, when the channel quality of the corresponding RS is inferior to a given threshold, a beam failure recovery and wireless link rebuild procedure may be triggered. Although this procedure is event-driven and has lower latency compared to gNB scheduling, the wireless link may have experienced significant performance loss. If transmission parameter settings are provided to indicate detection information, the UE side can predict some potential performance / QoS loss and provide some alarms to the gNB side.

[0082] An RS for beam detection, including candidate beam identification, beam recovery, link recovery, beam failure detection, or beam validity detection, or for wireless link monitoring, may be associated with one or more transmission parameter settings. In some embodiments, based on the transmission parameter settings, the UE may predict whether or when some beam pair links are blocked or may go out of the range of available angles corresponding to a site (e.g., physical anchor) or virtual anchor. In some embodiments, based on the transmission parameter settings, the UE may predict whether or when some beam pair links that were blocked or went out of the range of available angles corresponding to a site or virtual anchor are automatically recovered.

[0083] The UE may report failure events corresponding to RS or transport parameter settings (e.g., failure events of virtual anchors or TRPs) to the gNB / BS via, for example, UCI, MAC-CE, or RRC signaling. The report may display an index corresponding to the failed RS or transport parameter setting or a timestamp of the predicted failure. In some embodiments, the report may display recommended RS or recommended transport parameter settings to assist subsequent beam management and data transmission. In some embodiments, the report may include channel state information (CSI) corresponding to the recommended RS or transport parameter settings.

[0084] In some embodiments, the channel state information (CSI) corresponding to the recommended RS or recommended transmission parameter setting may be superior to or not inferior to the threshold value. In some embodiments, the reporting may indicate that the recommended RS or recommended transmission parameter setting was not found to handle cases where no candidate solution for recovery is found.

[0085] When the UE receives a gNB response (e.g., DCI, MAC-CE, or RRC command), DL signal(s) may be received according to the recommended RS or transmission parameter settings. The QCL assumption, spatial domain filter, group information, or transmission parameter settings of the DL signal(s) may be determined according to the recommended RS or transmission parameter settings.

[0086] When the UE receives a gNB response (e.g., DCI, MAC-CE, or RRC command), UL signal(s) may be transmitted according to the recommended RS or transmission parameter settings. In some embodiments, the spatial relationship, group information, or transmission parameter settings of the UL signal(s) may be determined according to the recommended RS or transmission parameter settings.

[0087] The UE may report a recovery event corresponding to an RS or transmission parameter setting (e.g., an automatic recovery or valid event of a virtual anchor or TRP) via UCI, MAC-CE, or RRC signaling. The report may display a timestamp of the recovered RS or recovered transmission parameter setting or a predictable beam recovery to assist subsequent beam management and data transmission. In some embodiments, the report includes channel state information (CSI) corresponding to the recovered RS or recovered transmission parameter setting. In some embodiments, the channel state information (CSI) corresponding to the recovered RS or recovered transmission parameter setting may be superior to a threshold value or may not be inferior to a threshold value.

[0088] When the UE receives a gNB response, DL signal(s) may be received according to the recovered RS or recovered transmission parameter settings. In some embodiments, the QCL assumption, spatial domain filter, group information, or transmission parameter settings of the DL signal(s) may be determined according to the recovered RS or recovered transmission parameter settings. For example, the DL signal (e.g., CSI-RS) may be received by the UE to probe a recovered beam link, such as for DL ​​beam refinement.

[0089] When the UE receives a gNB response, UL signal(s) may be transmitted according to the recovered RS or recovered transmission parameter settings. Additionally, the spatial relationship, group information, or transmission parameter settings of the UL signal(s) may be determined according to the recovered RS or recovered transmission parameter settings. For example, UL signals (e.g., SRS) may be transmitted by the UE to probe the recovered beam link, such as for UL beam refinement.

[0090] Now, referring to FIG. 7, a block diagram of a system (700) for a life / death procedure of a beam / physical link with the assistance of a virtual anchor is shown. As shown, a link failure or active procedure of one of the beam and physical links can be detected. UE T n From T n When moving to +x, based on the transmission parameter settings, the UE can estimate that there may be a failure in the beam pair link and then report this event to the TRP in advance. After that, the UE T n From +x, T n When moving to +y, the original link can be automatically restored, and then the UE can report a restoration event corresponding to the transmission parameter settings (e.g., virtual anchor).

[0091] VI. Process for Performing Sensing Information Assistance Beam Management

[0092] Now, referring to FIG. 8, a method (800) for performing sensing information assist beam management is illustrated. The method (800) may be implemented or performed using any of the components described above, such as a UE (104 or 204) and a BS (102 or 202), among others. Briefly, a wireless communication node may transmit a signaling that includes transmission parameter settings (805). A wireless communication device may receive a signaling that includes transmission parameter settings (810). A wireless communication node may transmit a signaling for beam states (815). A wireless communication device may receive a signaling for beam states (820). A wireless communication device may associate transmission parameter settings with resource-related information (825). A wireless communication device may communicate signals with a communication node (820, 825).

[0093] More specifically, a wireless communication node (e.g., BS (102, 202)) may transmit, provide, or otherwise transmit a signaling (here sometimes referred to as the first signaling) comprising at least one transmission parameter setting to a wireless communication device (e.g., UE (104, 204)) (805). The signaling may be transmitted to provide one or more transmission parameter settings to the wireless communication device to perform sensing information assist beam management. In some embodiments, the signaling may be an uplink (UL) signal between the wireless communication node and the wireless communication device or may include this. In some embodiments, the signaling may be a downlink (DL) signal between the wireless communication node and the wireless communication device or may include this. In some embodiments, the signaling may be based on various types of signaling, such as System Information Block (SIB) signaling, Master Information Block (MIB) signaling, Media Access Control Element (MAC-CE) signaling, or Radio Resource Control (RRC) signaling.

[0094] Signaling may configure one or more transmission parameter settings available to a wireless communication device, or define them, or not. A transmission parameter setting may define, correspond to, or not represent sensing information associated with an anchor. An anchor may be a virtual anchor or a physical anchor. A virtual anchor may be intended to assist beam determination by the wireless communication device. A physical anchor may correspond to a transmit / receive point (TRP), such as a wireless communication node or another communication node. In some embodiments, signaling may identify or include a pool of transmission parameter settings. A pool may identify or include one or more transmission parameter settings. A pool of transmission parameter settings may be associated with a pool of beam states. In some embodiments, each transmission parameter setting may correspond to or be associated with a group of reference signals (RS). In some embodiments, a transmission parameter setting may be sensing information associated with each set of sub-entities of the anchor.

[0095] The transmission parameter settings may define, identify, or include location information. The location information may identify or include the location of an anchor, a reflector, and an obstacle. A reflector may correspond to a plane where a beam communicated between a wireless communication node and a wireless communication device is reflected or its direction is changed. An obstacle may correspond to an object between the wireless communication node and the wireless communication device that affects the communication of the beam.

[0096] The transmission parameter setting may also define, identify, or include size information. In some embodiments, the size information may identify or include a radius or length defining, among others, an anchor, TRP, or reflector. The radius and length may be defined in terms of two or three dimensions. In some embodiments, the size information may identify or include the size of an anchor, reflector, or obstacle. The size may be in terms of two or three dimensions. Additionally, the transmission parameter setting may define, identify, or include a range of angles. The range of angles may identify or include a range of available angles for the anchor. The range of angles may identify or include a range of arrival angles (AoA) for the anchor. The range of angles may identify or include a range of departure angles (AoD) for the anchor.

[0097] The transmission parameter settings may also define, identify, or include diffusion information. The diffusion information may correspond, with or without, to position information, size information, or ranges of angles, among other things. The diffusion information may define, indicate, or include, a range of values ​​for various types of position information, size information, or ranges of angles as described above. In some embodiments, the diffusion information for a range of angles may identify or include angle diffusion. Angle diffusion may define, identify, or include, among other things, arrival azimuth diffusion, arrival zenith diffusion, arrival elevation diffusion, departure azimuth diffusion, departure zenith diffusion, or departure elevation diffusion. In some embodiments, the sensing information associated with each sub-entity for the anchor may identify or include position information, size information, or ranges of angles for the sub-entity.

[0098] A wireless communication device may receive, retrieve, identify, or otherwise receive a signaling containing transmission parameter settings from a wireless communication node (810). Upon reception, the wireless communication device may parse the signaling to extract or identify the transmission parameter settings. Through identification, the wireless communication device may identify location information, size information, or ranges of angles. In some embodiments, upon receiving the first signaling, the wireless communication device may wait for another signaling to initiate detection information assist beam management. In some embodiments, the wireless communication device may initiate detection information assist beam management in response to the reception of the signaling.

[0099] A wireless communication node may transmit, provide, or otherwise transmit signaling for beam states to a wireless communication device (815). In some embodiments, the wireless communication node may transmit signaling to enable (or disable) a subset of a pool of beam states. The signaling may identify a subset of the pool of beam states to be enabled (or disabled). A subset of the pool of beam states may correspond to a subset of the pool of transmission parameter settings. In some embodiments, the signaling may correspond, map, or associate a plurality of beam states with a code point. A plurality of beam states may be associated with at least one of the transmission parameter settings. In some embodiments, a plurality of beam states includes a first set of beam states to be applied to downlink signals and a second set of beam states to be applied to uplink signals. In some embodiments, the signaling may specify, identify, or otherwise indicate a beam state from a subset of the pool of beam states. A beam state may be applied to downlink signaling or uplink signaling. In some embodiments, the signaling may identify, among others, downlink control information (DCI) signaling, media access control element (MAC-CE) signaling, or radio resource control (RRC) signaling. When a radio communication node receives a gNB response (e.g., DCI, MAC-CE, or RRC command), the signaling may be received according to the recommended RS or transmission parameter settings.

[0100] A wireless communication device may receive signaling for beam states from a wireless communication node, either retrieve, identify, or otherwise receive (820). In some embodiments, the wireless communication device may receive signaling to enable (or disable) a subset of a pool of beam states. Upon receiving, the wireless communication device may parse the signaling to identify the subset of the pool of beam states to be enabled. In some embodiments, the wireless communication device may receive signaling to indicate a beam state from a subset of the pool of beam states. Upon receiving, the wireless communication device may parse the signaling to identify a beam state from the subset.

[0101] A wireless communication device may associate, map, or otherwise associate a transmission parameter setting with resource-related information (825). Resource-related information may identify, among others, a reference signal (RS), beam state, group information, reporting configuration, bandwidth part (BWP), component carrier (CC), control resource set (CORESET) pool, and uplink power control parameters, or include these. Group information may include, among others, a grouping of one or more RSs, a resource set, a panel, a sub-array, an antenna group, an antenna port group, a group of antenna ports, a beam group, a transmission entity / unit, or a reception entity / unit, or correspond thereto. In some embodiments, the RS may identify, among others, an RS port, an RS group, an RS resource, an RS resource set, or an RS resource setting, or include these. In some embodiments, the RS may identify or include a synchronization signal block (SSB) or a channel state information reference signal (CSI-RSS). In some embodiments, the RS may be associated with one or more transmission parameter sets.

[0102] In association, the wireless communication device may determine transmission parameter settings using subsequent signaling. In some embodiments, the wireless communication device may identify or determine transmission parameter settings associated with an indicated beam state. The beam state may be indicated in subsequent signaling. In some embodiments, the wireless communication device may identify, select, or determine at least one transmission parameter setting from a plurality of transmission parameter settings. At least one transmission parameter setting may be determined to be valid and applied to a signal for beam management. In some embodiments, the wireless communication device may identify or select a transmission parameter setting to use from a pool of transmission parameter settings.

[0103] A wireless communication device can communicate signals with a communication node (830, 835). In some embodiments, the wireless communication device can transmit, transmit, or communicate signals according to resource-related information. In some embodiments, the wireless communication device can transmit, transmit, or communicate signals according to transmission parameter settings. When communicating, the wireless communication can transmit or communicate RS. RS may consist of beam state or group information. The beam state or group information may be associated with transmission parameter settings. The transmission parameter settings may be included in or associated with the beam state or group information. In some embodiments, a signal containing RS may be associated with an identified transmission parameter setting to be used. RS may be used for beam detection, wireless link monitoring, candidate beam identification, beam recovery, and link recovery, among other things. In some embodiments, the signal may include a downlink signal (e.g., for a data or control channel such as PDCCH or PDSCH) or an uplink signal (e.g., for data or control such as PUCCH or PUSCH).

[0104] During communication, the wireless communication device may retrieve, identify, or otherwise receive a downlink signal depending on the RS or transmission parameter settings. The downlink signal may be received from a wireless communication node. In some embodiments, the beam state, spatial relationship, spatial domain filter, or group information of the downlink signal may be determined (e.g., by the wireless communication node) depending on the RS or transmission parameter settings. In some embodiments, the wireless communication device may also transmit, provide, or otherwise transmit an uplink signal depending on the RS or transmission parameter settings. The uplink signal may be transmitted to a wireless communication node. In some embodiments, the beam state, spatial relationship, group information, or spatial domain filter of the uplink signal may be determined (e.g., by the wireless communication device) depending on the RS or transmission parameter settings.

[0105] In some embodiments, the wireless communication device may transmit, provide, or otherwise transmit a report (e.g., to a wireless communication node). In some embodiments, the wireless communication device may perform or perform measurements corresponding to the reporting configuration according to the transmission parameter settings. The measurements may be included in the report transmitted by the wireless communication device. The report may be, among others, part of or include uplink control information (UCI) signaling, media access control element (MAC-CE) signaling, or radio resource control (RRC) signaling.
