[0002] The present disclosure is generally related to communication and sensing systems and, more particularly, to reporting multi-dimensional parameters with respect to apparatus in communication and sensing systems.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] In New Radio (NR) architecture, various techniques have been developed to support communication and / or sensing functionalities. For example, Multiple-Input Multiple-Output (MU-MIMO) systems and Integrated Sensing and Communication (ISAC) systems have been proposed and utilized.
[0005] In particular, regarding MIMO systems, multiple spatially separated transmit and receive antennas may be utilized to support multiple signal paths and to improve spectral efficiency, link reliability, and spatial multiplexing capability. Regarding ISAC systems, simultaneous environmental sensing and wireless communication may be enabled by reusing shared waveform resources (e.g., Orthogonal Frequency-Division Multiplexing (OFDM) signals) .
[0006] However, in such communication and / or sensing systems, existing mechanisms for reporting related parameters, such as channel-related parameters or sensing-related parameters, may not be optimized, which may result in significant signaling overhead.
[0007] Accordingly, improving the efficiency of reporting communication-related and / or sensing-related parameters has become an important issue in newly developed wireless communication networks. There is therefore a need for schemes that may improve the efficiency of reporting such communication-related and / or sensing-related parameters.SUMMARY

[0022] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0023] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to reporting multi-dimensional parameters with respect to apparatus in communication and sensing systems. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0024] Regarding the present disclosure, a User Equipment (UE) may determine at least one multi-dimensional vector parameter. Each multi-dimensional vector parameter may correspond to a physical propagation component. The UE may determine at least one block based on the at least one multi-dimensional vector parameter. Each block may be associated with a boundary. The UE may report the at least one block to a network node.
[0025] The network node may receive the report associated with the at least one block from the UE. The network node may determine the at least one multi-dimensional vector parameter based on the report associated with the at least one block.
[0026] Accordingly, by utilizing the at least one block, the network and the UE may more efficiently report the at least one multi-dimensional vector parameter, such as some communication-related and / or sensing-related parameters.
[0027] FIG. 1 illustrates an example scenario 100 under schemes in accordance with implementations of the present disclosure. Scenario 100 involves at least one network node and a UE, which may be a part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network) . Scenario 100 illustrates the current network framework. The UE may connect to the network side. The network side may comprise one or more network nodes.
[0028] In some embodiments, the network node and the UE may predefine block (s) (e.g., cluster (s) ) for reporting network parameters. In some cases, the network node may predetermine the block (s) and preconfigure the block (s) to the UE. In some cases, the UE may predetermine the block (s) and inform the network of the predetermined block (s) .
[0029] Then, the UE may determine at least one multi-dimensional vector parameter. More specifically, each multi-dimensional vector parameter may correspond to a physical propagation component. For example, the physical propagation component includes a path of MIMO and / or a sensing target. When the physical propagation component includes the path of MIMO, the UE measures the path to determine a multi-dimensional vector parameter including network parameters such as Azimuth angle of Departure (AoD) from the network node, Elevation angle of Departure (ZoD) from the network node, path delay, and / or Doppler shift. When the physical propagation component includes the sensing target, the UE obtains sensing information as a multi-dimensional vector parameter including network parameters such as range, Doppler, azimuth angle, and elevation angle associated with the sensing target.
[0030] After determining the at least one multi-dimensional vector parameter, the UE may determine (e.g., select) at least one block based on the at least one multi-dimensional vector parameter. Each block may be associated with a boundary. More specifically, the UE may determine the at least one block by identifying one or more blocks whose boundaries cover the at least one multi-dimensional vector parameter, such that the at least one multi-dimensional vector parameter may be within the boundaries of the identified one or more blocks.
[0031] After determining the at least one block, the UE may report the at least one block to the network node. The network node may receive the report associated with the at least one block from the UE. The network node may determine the at least one multi-dimensional vector parameter based on the report associated with the at least one block. More specifically, the network node may determine the at least one multi-dimensional vector parameter by reconstructing the at least one multi-dimensional vector parameter based on block-related information included in the report.
[0032] Accordingly, by utilizing the at least one block, the UE may not be required to report each multi-dimensional vector parameter individually over an entire parameter space. Instead, the UE may indicate one or more blocks corresponding to regions of the parameter space in which the multi-dimensional vector parameters are located, and report block-related information associated with the indicated blocks. Since each block may represent a bounded region of a parameter space, the block-related information may enable the network node to determine one or more multi-dimensional vector parameters with reduced signaling overhead, as compared to reporting the multi-dimensional vector parameters individually.
[0033] In some implementations, there may be some scenarios in communication and sensing systems where a device (i.e., the UE) needs to signal a D-dimensional (or D-tuple) vector parameter to another device (i.e., the network node) .
[0034] For example, k denotes a D-dimensional vector parameter as: k = (k1, k2, …, kD) where 0≤k1≤N1, 0≤k2≤N2, …, 0≤kD≤ND and N1, N2, …, ND are assumed to be integers without loss of generality. In some cases, if N1 is not an integer, the UE may instead signal a normalized parameter k′d = kd / Nd, in which case N′d = 1 is an integer. A lower limit of these elements of D-dimensional vector parameter may be set to 0 without loss of generality. In some cases, if the UE may instead signal an offset parameter together with
[0035] When there are Q such D-dimensional vector parameters, these D-dimensional vector parameters may be denoted as: kq = (k1, q, k2, q, …, kD, q) for q = 1, 2, …, Q or in vector form: kq = [k1, q k2, q … kD, q] T, q = 1, 2, …, Q
[0036] FIG. 2 illustrates an example scenario 200 under schemes in accordance with implementations of the present disclosure. For example, elements in a 4-dimensional vector parameter are path parameters of a MIMO channel. The 4-dimensional vector parameter is denoted as kq = (k1, q, k2, q, k3, q, k4, q) . In this example, the elements include an Azimuth angle of Departure (AoD) φ from the network node, Elevation angle of Departure (ZoD) θ from the network node, a path delay τ, and a Doppler shift ν. Therefore, path 1 of the MIMO channel is represented as k1 = (k1, 1, k2, 1, k3, 1, k4, 1) or k1 = (φ1, θ1, τ1, ν1) , and path 2 of the MIMO channel is represented as k2 = (k1, 2, k2, 2, k3, 2, k4, 2) or k2 = (φ2, θ2, τ2, ν2) .
[0037] Further, the MIMO channel observed by a single receive antenna may be expressed as a 4-Dimensional tensor h (i, j, m, n) while where i, j, m, n are integer indices within certain range. i is the azimuth antenna index. j is the elevation antenna index. m is the frequency index in a pre-specified unit δf (a sub-carrier for example) . n is the time index in a pre-specified unit δt (an OFDM symbol for example) . λq is the complex channel gain for the q-th path. The present disclosure may relate to the quantization and reporting of kq = [φq θq τq νq] T.
[0038] It should be noted that, in another example, these elements in the 4-Dimensional vector parameter may include parameters used in a 4-D sensing system. It is not intended to limit the content of the D-dimensional vector parameter. People skilled in the art should readily understand that, for different network scenarios, different parameter definitions may be applied.
[0039] In some implementations, a D-dimensional tensor h of size (N1, N2, …, ND) may be considered where D is the number of dimensions, Nd is the size of the d-th dimension, and size (h) = (N1, N2, …, ND) . The tensor h (n1, n2, …, nD) may be denoted as: which is the linear weighted sum of Q basis functions, where nd = 0, 1, …, Nd-1 for all d = 1, …D, and 0≤kd, q<Nd is a real number that determines the sinusoidal basis function. Quantized kd, qand / or quantized λq (or |λq| depending on the application) may need to be reported to the network node. The present disclosure may introduce an efficient quantization of 0≤kd, q<Nd for all d and q.
[0040] In addition, the q-th basis function may be parameterized by kd, q for d = 1, …, D. The vector parameter that determines the q-th basis function may be denoted as kq = [k1, q … kD, q] T. In some cases, kq may be considered as a D-dimensional coordinate. In some cases, the size Nd of the tensor h may not need to be the same as an upper limit of the value kd, q.
[0041] The present disclosure may relate to the quantization and reporting of the vector parameter kq (and optionally λq) that determine the basis functions, which in turn determine (together with λq) values of a tensor at given indices (n1, n2, …, nD) . In some cases, reconstruction of the original tensor may not be necessary so that the complex coefficient λq may not be reported.
[0042] In some cases, the size Nd for each dimension may be chosen to be the basic number of gridlines, and the parameter kd, q may be quantized accordingly, such that kd, q∈ {0, 1, 2, …, Nd-1} . Based on the gridlines and quantization, a basic unit grid (also referred to as a global grid) may be determined. Further, a grid (also referred to as a local grid) having higher resolution within the basic unit grid may be introduced by using additional parameters.
[0043] In some cases, the d-th dimension in the tensor may correspond to the ordered antenna index of a uniform linear array. In such cases, exp(j2πkd, qnd / Nd) , nd = 0, …, Nd-1 may represent a phase response at the nd-th antenna element corresponding to a single plane wave impinging on the array with an angle of incidence θ = cos-1(kd, q / Nd) .
[0044] In some implementations, there may be multiple D-dimensional tensors of the same size sharing the same set of kd, q but different λq. In some cases, where each hr, r = 1, …, R is a D-dimensional tensor of size (N1, N2, …, ND) with linear combination coefficients λr, q. Accordingly, where
[0045] For example, h1, …, hR are tensors corresponding to different RX antennas, hv, hh are tensors corresponding to TX antennas of vertical and horizontal polarization.
[0046] It should be noted that, without loss of generality, a single tensor may be introduced in the following description.
[0047] In some implementations, the at least one multi-dimensional vector parameter may be distributed in the at least one block. In particular, multi-dimensional vector parameter (s) , denoted as kq = [k1, q … kD, q] T, q = 1, …, Q, may be distributed in B blocks. Each block may be a multi-dimensional rectangle. In some cases, 0≤kd, q<Nd for all d = 1, …, D and q = 1, …, Q.
[0048] In some implementations, the boundary of each block may include: (1) a plurality of starting points; and (2) a plurality of ending parameters. Each starting point may correspond to a respective dimension associated with each multi-dimensional vector parameter. Each ending parameter may correspond to a respective dimension associated with each multi-dimensional vector parameter. In some cases, each ending parameter may include an ending point or a length.
[0049] More specifically, for block b = 1, 2, …, B, (1) may represent a starting point of b-th block of the d-th dimension, (2) may represent an ending point of b-th block of the d-th dimension, and (3) may represent a corresponding length so that There may be boundary-related parameters such as:
[0050] In some cases, the blocks may be non-overlapping. In some cases, the blocks may be overlapping. In some cases, the ending point may be optional and may be omitted depending on the per block indication scheme (e.g., using length instead of ending point ) .
[0051] In some implementations, each block may correspond to a region defined by one or more global grids. Each global grid may represent a first quantization unit (e.g., the basic grid unit) for respective dimensions associated with each multi-dimensional vector parameter. In some cases, each global grid may be defined by first quantization parameters for dimensions associated with each multi-dimensional vector parameter. In some cases, each first quantization parameter may include a positive integer or a positive rational number.
[0052] More specifically, the global grid (s) may be defined by the first quantization parameters (also referred to as an over-sampling factor) d: {o1, …, od, …, oD} for each dimension of the D-dimensional vector parameter. Each element od in the oversampling factor may be a positive integer or a positive rational number.
[0053] In some cases, for the d-th dimension, an interval [0, Nd) may be divided into equally spaced grids of length as: where gd denotes a set of global grid points for the d-th dimension, and the set {g1, …, gd, …, gD} is referred to as the global grid (s) .
[0054] In some cases, a starting point of a block and a corresponding ending point (if present) of the block may be defined on the global grid. More specifically, the starting point and the ending point The corresponding vector form may be denoted as: In some case and may be expressed as an integer part and a fractional part.
[0055] In some implementations, the region may include a plurality of local grids. Each local grid may represent a second quantization unit within a corresponding block for respective dimensions associated with each multi-dimensional vector parameter. In some cases, each local grid may be defined by second quantization parameters for dimensions associated with each multi-dimensional vector parameter. In some cases, each second quantization parameter may include a positive integer or a positive fractional value.
[0056] More specifically, the local grid (s) may be defined per block per dimension. The local grid (s) may be block-specific grid (s) defined by the second quantization parameters (also referred to as an over-sampling factor) for the b-th block of the d-th dimension. There may be the second quantization parameters as:
[0057] In some cases, for the b-th block of d-th dimension, an interval may be divided into equally spaced grids of length as: where is the set of local grid points for the b-th block in the d-th dimension
[0058] In some cases, an entry kd, q lying in the b-th block may be defined on the local grids. More specifically, the entry
[0059] In some cases, when the local grids may be the same as the global grids in the d-th dimension.
[0060] In some cases, may be fractional. For example, In these cases, the local grids within the b-th block may revert to the global grid (i.e., the basic unit grid) possibly with a fractional offset. Such an arrangement may ensure the selected basis functions are orthogonal within the block.
[0061] FIG. 3 illustrates an example scenario 300 under schemes in accordance with implementations of the present disclosure. For example, consider a case with two dimensions (i.e., D=2, corresponding to one dimension d=1 and the other dimension d=2) and two blocks (B=2, corresponding to b=1 and b=2) . Block b=1 has: (1) a starting point an ending point and a length in dimension d=1, and (2) a starting point an ending point and a length in dimension d=2. Block b=2 has: (1) a starting point an ending point and a length in dimension d=1, and (2) a starting point an ending point and a length in dimension d=2.
[0062] FIG. 4 illustrates an example scenario 400 under schemes in accordance with implementations of the present disclosure. For example, for the d-th dimension, the corresponding first quantization parameter (i.e., the oversampling value od) corresponding to the global grid is set to four. For the b-th block in the d-th dimension, the corresponding second quantization parameter (i.e., the oversampling value ) corresponding to the local grid is set to four. In this example, the starting point and the ending point of the b-th block are defined on the global grids.
[0063] FIG. 5 illustrates an example scenario 500 under schemes in accordance with implementations of the present disclosure. For example, for the d-th dimension, the corresponding first quantization parameter (i.e., the oversampling value od) corresponding to the global grid is set to four. For the b-th block in the d-th dimension, the corresponding second quantization parameter (i.e., the oversampling value ) corresponding to the local grid is set to one quarter. In this example, the starting point and the ending point of the b-th block are defined on the global grids. The local grids within the b-th block revert to the global grids (possibly with a fractional offset) .
[0064] In some implementations, the multi-dimensional vector parameter kq that determines the q-th basis function may be in at least one block. In some cases, the coordinate kq may lie in more than one block, for example, when blocks overlap. In such cases, the coordinate kq may be defined in one block.
[0065] In some cases, when the multi-dimensional vector parameter kq indicating the q-th basis function is included in the b-th block, kd, q in kq may be expressed as: or equivalently, kd, q may be indicated by the two-tuple The parameter may be expressed as an integer part and a fractional part as or a two tuple where and The parameter may be expressed as an integer part and a fractional part. Accordingly, a combination of may be represented as a four-tuple.
[0066] In some implementations, the at least one block may include a first block. The first block may be reported with information including a coordinate list, a bitmap or a combinational indication. The information may indicate at least one multi-dimensional vector parameter location within the first block.
[0067] In some cases, the first block may be reported with the coordinate list. In particular, the coordinate list may be used to identify locations of one or more multi-dimensional vector parameters within the first block. More specifically, may denote a set of indices q∈{1, 2, …, Q} associated with b-th block, where |q (b) | = Qb may denote the number of paths in the b-th block. The coordinate list may be represented as: for all in q (b) in a pre-specified order.
[0068] For example, the coordinate list is arranged in ascending order based on and in an event of a tie, the corresponding entries are further arranged in ascending order based on and so on for subsequent dimensions.
[0069] In some cases, the first block may be reported with the bitmap. In particular, the bitmap may be used to identify the locations of one or more multi-dimensional vector parameters within the first block. More specifically, may denote the number of quantization levels for the b-th block in the d-th dimension. The UE may report an multi-dimensional bitmap, in which a value of 1 may indicate the presence of a multi-dimensional vector parameter, and a value of 0 may indicate the absence of a corresponding multi-dimensional vector parameter.
[0070] It should be noted that, for reporting the multi-dimensional bitmap more efficiently, techniques such as Run-Length Encoding (RLE) and / or Huffman Coding may be introduced to further reduce signaling overhead.
[0071] In some implementations, the first block may be reported with the combinational indication. In particular, the combinational indication may be used to efficiently indicate the locations of one or more multi-dimensional vector parameters within the first block. More specifically, may denote the number of quantization levels for the b-th block in the d-th dimension, and may denote all the number of quantization levels for the b-th block for all D dimensions. Qb may denote the number of non-zero entries in the b-th block. Parameter may be reported as: where
[0072] In addition, where may be a linear index of the D-dimensional subscripts Accordingly, reporting the parameter may then be equivalent to reporting a single integer ξb which may be expressed as:
[0073] In some cases, number of bits required to indicate the basis functions in the b-th block may be It should be noted that, by definition, and
[0074] In some implementations, the previous grid system may be cyclical. In particular, regarding the starting point and the ending point associated with the b-th block in the d-th dimension, Regarding the set of global grid points gd for the d-th dimension, gd≡gd mod Nd, γd≡γd mod Nd.
[0075] In some implementations, additional parameters may be reported from the UE to the network node. In particular, in addition to the report of the multi-dimensional vector parameter kq = [φq θq τq νq] T, q = 1, …, Q following parameters may be reported.
[0076] In some cases, a complex channel gain λq may be reported along with its associated coordinate kq in a corresponding order when the coordinate kq indicates an element in a multi-dimensional basis with λq as the basis element’s linear combination coefficients.
[0077] In some cases, a real value |λq| or |λq|2 may be reported instead of the complex value λq.
[0078] In some cases, an energy per-block (per-cluster) ∑q∈q (b) |λq|2 may be reported for b = 1, 2, …, B, where may be the set of q∈ {1, 2, …, Q} that are in the b-th block.
[0079] In some cases, a Signal to Noise Ratio (SNR) value may be reported, where N0 may be the power of the noise and interference.
[0080] In some cases, an SNR value may be reported per block, where may be the power of the noise and interference in the b-th block. Illustrative Implementations

[0112] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0113] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0114] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
