Methods of information feedback and instructions

[0001] Cross-reference to related applications

[0002] This disclosure is based on Chinese Patent Publication 2024106741133, filed on May 28, 2024, entitled “Method for Information Feedback and Instruction”, and claims priority to that patent disclosure, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communications, and more specifically, to a method for information feedback and instruction. Background Technology

[0004] Distributed Multiple-Input Multiple-Output (Distributed MIMO) and Cell-Free Massive Multiple-Input Multiple-Output (CF-MIMO) are gaining increasing attention as potential key technologies for multi-antenna architectures in B5G / 6G. A significant characteristic of this technology is that the spatial distribution of Access Points (APs) within a given area is more dispersed compared to the centralized APs currently used in NR, and the number of APs is greater than the number of User Equipment (UEs), with multiple APs simultaneously serving multiple UEs.

[0005] In New Radio (NR), the Channel State Information Reference Signal (CSI-RS) can be used for downlink CSI measurement and feedback. The complete CSI measurement and feedback process on the UE side includes: the UE receiving CSI-RS configuration information, the UE measuring the CSI-RS transmitted by the BS based on the CSI-RS configuration information, and the UE providing downlink CSI feedback based on the CSI-RS measurement results. The specific time-frequency resource for the BS to transmit CSI-RS is called the CSI-RS resource. The logical antenna port carrying the CSI-RS resource is called the CSI-RS port. The number of CSI-RS ports supported in NR is {1, 2, 4, 8, 12, 16, 24, 32}. When there are 4 or more CSI-RS ports, the horizontal and vertical dimensions of the 2D antenna panel are determined by N1 and N2, respectively; currently, only a limited combination of N1 / N2 is supported for a given CSI-RS port. Configurable parameters for CSI-RS resources include CSI-RS port, density, periodicity and offset, code division type, power control offset, and quasi-co-addressability. To ensure flexible CSI-RS measurements, NR divides CSI-RS resources into two levels for configuration: CSI-RS resource sets and CSI-RS resource settings. A CSI-RS resource set consists of one or more CSI-RS resources, while a CSI-RS resource setting consists of one or more CSI-RS resource sets. Only the time-domain characteristic parameters (periodic, semi-persistent, aperiodic) of a CSI-RS resource are configured in the CSI-RS resource setting; other parameters are configured in the CSI-RS resource set. Different CSI-RS resources within the same CSI-RS resource set have the same CSI-RS port and density. Codebook-based CSI feedback supports codebook types including "typeISinglePanel", "typeIMulti-Panel", "typeII", and "typeII-r16".

[0006] In future-oriented CF-MIMO application scenarios, such as large stadiums, shopping malls, airports, and automated factories, the spatial distribution of UEs will become highly complex, with some areas having a high density of UEs and others having a sparse density. Furthermore, the quality of service requirements of UEs in different spatial locations may vary significantly. Some UEs have extremely high capacity requirements, such as Extended Reality (XR) devices, while others have extremely high latency requirements, such as industrial automation equipment. In addition, as the scale of network nodes increases exponentially, operating costs and energy consumption become significant challenges. To effectively address these issues, heterogeneous large-scale distributed networks can be constructed using distributed units with different antenna sizes, and flexible joint coherent transmission schemes can be used to meet various service requirements. However, current technologies do not support such solutions. Summary of the Invention

[0024] This embodiment provides a method for information feedback running on the aforementioned computer terminal. Figure 2 is a flowchart of the information feedback method according to an embodiment of this disclosure. Applied to a terminal, as shown in Figure 2, the process includes the following steps:

[0025] Step S202: Receive indication information for Channel State Information Reference Signal (CSI-RS) measurement and determine the feedback codebook based on the indication information, and use the feedback codebook to provide channel state information feedback.

[0026] In one exemplary embodiment, the indication information includes at least one of the following: first indication information for indicating parameters of the basic antenna element and the extended antenna element; and second indication information for determining the feedback codebook of the extended antenna element.

[0027] In an exemplary embodiment, the first indication information includes at least one of the following: the horizontal dimension N1_s of the basic antenna element; the vertical dimension N2_s of the basic antenna element; the number Kg of the access point (AP) groups of the extended antenna element; and the set of horizontal and vertical extension parameter groups of the AP groups of the extended antenna element {(Ms_ap_1,Ns_ap_1),...,(Ms_ap_i,Ns_ap_i),...,(Ms_ap_Kg,Ns_ap_Kg)}; wherein, N1_s is 2, 3, 4, 6, or 8, N2_s is 1 or 2, Kg is 2, 3, or 4, i is a positive integer not exceeding Kg, Ms_ap_i is 1, 2, 3, 4, or 6, Ns_ap_i is 1, 2, 3, or 4, and Np_ap_i is 4, 8, 12, 16, 24, or 32.

[0028] In one embodiment, as shown in Table 1, the (N1_s, N2_s) values ​​of the basic antenna element are configured with no more than 16 ports, and the (N1_ap_i, N2_ap_i) values ​​of the extended antenna element are all configured with no more than 32 ports. However, the extended antenna element is composed of the basic antenna element, so there is a constraint relationship between the two configurations. In addition, the number of resources in a set does not exceed 8, the number of groups does not exceed 4, and each group has at least 1 resource, further constraining the configuration possibilities. All embodiments in this disclosure are based on Table 1.

[0029] Table 1

[0030] In one exemplary embodiment, the extended antenna element is generated in at least one of the following ways: the basic antenna element is extended in the horizontal direction to generate the extended antenna element; the basic antenna element is extended in the vertical direction to generate the extended antenna element; the basic antenna element is extended in both the horizontal and vertical directions to generate the extended antenna element.

[0031] In one embodiment, the basic antenna element is a dual-polarized uniform planar array (UPA) or a uniform linear array (ULA). The extended antenna element is composed of multiple sets of basic antennas, thus it is a heterogeneous antenna element composed of multiple sets of UPAs or ULAs. The extended antenna element can be constructed from basic antenna elements in the following ways: horizontal expansion, vertical expansion, and simultaneous horizontal and vertical expansion. Horizontal expansion involves expanding multiple basic antenna elements row-wise while maintaining the column count; vertical expansion involves expanding multiple basic antenna elements column-wise while maintaining the row count; and simultaneous horizontal and vertical expansion involves simultaneously expanding multiple basic antenna elements both column-wise and row-wise.

[0032] In one exemplary embodiment, basic antenna elements and extended antenna elements are configured in a CSI-RS resource set. A CSI-RS resource set includes Kg CSI-RS resource groups, and each CSI-RS resource group includes Kr_i CSI-RS resources. The number of CSI-RS resources in a CSI-RS resource set is Ks. Each CSI-RS resource in a CSI-RS resource set corresponds to one basic antenna element, and each CSI-RS resource group corresponds to one access point (AP) group of extended antenna elements. The number of ports in a CSI-RS resource is Np, and the number of ports in a CSI-RS resource group is Np_ap_i. Here, Kr_i is a positive integer less than or equal to 7, Ks is 2, 3, 4, 5, 6, 7, or 8, and Np is 4, 8, 12, or 16. Np_ap_i=Np*Kr_i, Np=2*N1_s*N2_s.

[0033] It should be noted that the relevant protocols stipulate that each CSI-RS Resource in a CSI-RS Resource set has completely identical antenna parameter configurations. Without changing the existing CSI-RS configuration framework, in this embodiment of the disclosure, to support joint coherent transmission of antenna elements of different sizes, different CSI-RS Resource groups are constructed within a CSI-RS Resource set. Each CSI-RS Resource group corresponds to one AP group. The CSI-RS Resource of each AP group is defined as a basic antenna element. All CSI-RS Resource groups constitute an extended antenna element.

[0034] In one exemplary embodiment, the second indication information includes at least one of the following: the type of feedback codebook; the AP group broadband precoding selection method of the extended antenna element; and the AP group subband precoding selection method of the extended antenna element.

[0035] In one exemplary embodiment, the AP group broadband precoding selection method for the extended antenna element includes independent selection or joint selection.

[0036] In one exemplary embodiment, the AP group subband precoding selection method for the extended antenna element includes independent selection or joint selection.

[0037] In one exemplary embodiment, when the broadband precoding selection mode of the AP group of the extended antenna element is independent, each AP group independently selects broadband precoding.

[0038] In an exemplary embodiment, when the broadband precoding selection method for the AP group in the extended antenna unit is joint selection, when the antenna configurations of all AP groups in the extended antenna unit are completely different, each AP group independently selects broadband precoding; when the antenna configurations of some AP groups in the extended antenna unit are the same, the broadband precoding selection method of AP groups with the same antenna configuration is the same, and AP groups with different antenna configurations independently select broadband precoding.

[0039] In one exemplary embodiment, when the AP group subband precoding selection method of the extended antenna element is independent selection, each AP group independently selects subband precoding.

[0040] In an exemplary embodiment, when the AP group subband precoding selection method of the extended antenna unit is joint selection, when the antenna configurations of all AP groups in the extended antenna unit are completely different, each AP group independently selects subband precoding. When the antenna configurations of some AP groups in the extended antenna unit are the same, the AP groups with the same antenna configuration select the same subband precoding method, and the AP groups with different antenna configurations select subband precoding independently.

[0041] In one embodiment, determining the extended antenna element codebook based on the typeISinglePanel codebook type includes the following process:

[0042] Step S2021: Determine the set of oversampling factors in the horizontal and vertical directions of the AP group of the extended antenna element according to the configuration information of the AP group of the extended antenna element: {(O1_ap_1,O2_ap_1),...,(O1_ap_i,O2_ap_i),...,(O1_ap_Kg,O2_ap_Kg)}.

[0043] Step S2022: Determine the broadband precoding W1 = [W] of the AP group of the extended antenna element based on the broadband precoding selection method, configuration information, and the sets of horizontal and vertical oversampling factors. 1_ap_1 ,…,W 1_ap_i ,…,W 1_ap_Kg ].

[0044] When the broadband precoding selection method of the AP group in the extended antenna unit is configured as AP group independent selection, then regardless of whether there are any parts that are the same in the configuration information of the AP group, each AP in the AP group of the extended antenna unit independently selects a broadband precoding.

[0045] For example, when the broadband precoding selection mode of the AP group in the extended antenna element is configured as AP group independent rotation, the configuration information of the AP group in the extended antenna element is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2)}={(2,1),(6,1)}, then W 1_ap_1 W 1_ap_2 Choose a wideband precoding code independently;

[0046] The configuration information of the AP group with extended antenna elements is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3)}={(2,1),{(2,1),(6,1), then W 1_ap_1 W 1_ap_2 W 1_ap_3 Choose a broadband precoder independently.

[0047] When the broadband precoding selection method of the AP group in the extended antenna unit is configured as AP group joint selection, if the antenna configuration of each AP in the AP group configuration information is completely different, each AP in the AP group of the extended antenna unit independently selects broadband precoding; if the antenna configuration of APs in the AP group configuration information is completely the same, then in the AP group of the extended antenna unit, multiple APs with the same configuration jointly select the same broadband precoding, and multiple APs with different configurations independently select broadband precoding.

[0048] For example, when the broadband precoding selection mode of the AP group in the extended antenna element is configured as AP group joint selection, the configuration information of the AP group in the extended antenna element is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3)}={(2,1),(4,1),(6,1)}, then W 1_ap_1 W 1_ap_2 W 1_ap_3 Choose a broadband precoder independently.

[0049] The configuration information of the AP group with extended antenna elements is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3),(N1_ap_4,N2_ap_4)}={(2,1),(2,1),(4,1),(6,1). Then W 1_ap_1 With W 1_ap_2 Jointly select a wideband precoding, W 1_ap_1 W 1_ap_3 W 1_ap_4 Choose a broadband precoder independently.

[0050] Step S2023: Determine the sub-band precoding W2 of the extended antenna element's AP group based on the sub-band precoding selection method, configuration information, and horizontal and vertical oversampling factor sets. 2_ap_1 ,…,W 2_ap_i ,…,W 2_ap_Kg ].

[0051] When the subband precoding selection method of the AP group in the extended antenna element is configured as AP group independent selection, each AP in the AP group of the extended antenna element independently selects subband precoding, regardless of whether there are any parts that are the same in the configuration information of the AP group.

[0052] For example, when the subband precoding selection mode of the AP group of the extended antenna element is configured as AP group independent rotation, the configuration information of the AP group of the extended antenna element is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2)}={(2,1),(4,2)}, then W 2_ap_1 W 2_ap_2 Select a subband for precoding independently.

[0053] The configuration information of the AP group with extended antenna elements is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3)}={(2,2),{(2,2),(4,2), then W 2_ap_1 W 2_ap_2 W 2_ap_3 Select a subband for precoding independently.

[0054] When the subband precoding selection method of the AP group in the extended antenna element is configured as joint selection of the AP group: If the antenna configuration of each AP in the AP group configuration information is completely different, each AP in the AP group of the extended antenna element independently selects the subband precoding; if the antenna configuration of APs in the AP group configuration information is completely identical, then in the AP group of the extended antenna element, multiple APs with the same configuration jointly select the same subband precoding, multiple APs with the same configuration jointly select the same subband precoding, and multiple APs with different configurations independently select the subband precoding.

[0055] For example, when the subband precoding selection mode of the AP group of the extended antenna element is configured as AP group joint selection, the configuration information of the AP group of the extended antenna element is {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3)}={(2,1),(4,2),(6,1)}, W 2_ap_1 W 2_ap_2 W 2_ap_3 Independently select a sub-band for precoding; extend the configuration information of the AP group of the antenna element {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2),(N1_ap_3,N2_ap_3),(N1_ap_4,N2_ap_4)}={(3,2),(3,2),(6,2),(6,2), then W 2_ap_1 With W 2_ap_2 Combine a subband precoding, W 2_ap_3 With W 2_ap_4 Combine a subband precoding, W 2_ap_1 W 2_ap_3 Select a subband for precoding independently.

[0056] Step S2024, as shown in formula (1), determines the feedback codebook W by wideband precoding and subband precoding of the AP group of extended antenna elements.

[0057] Specifically, the feedback codebook W of the AP group in the extended antenna element is formed by sequentially splicing the sub-codebooks of Kg APs. Whether the sub-codebooks of different APs in the AP group of the extended antenna element are jointly fed back to further reduce the feedback overhead is determined according to the scheme described in steps S2021 to S2024. γ is a power normalization factor, ensuring that the modulus value of each column of W is 1. The sub-codebook of AP i in the AP group of the extended antenna element is precoded by wideband W. 1_ap_i Subband precoding W 2_ap_i Determined jointly.

[0058] For example, for a dual-polarized UPA, when rank=1, one spatial basis vector V is selected. l_ap_iAs a broadband precoding method, the broadband precoding form is determined based on the antenna element configuration information (N1_ap_i, N2_ap_i). Subband precoding W 2_ap_i Through the phase difference between polarizations Quantization is performed using QPSK. 1_ap_i W 2_ap_i V l_ap_i and U m_ap_i As shown in formulas (2), (3), (4) and (5) respectively.

[0059] Where l = 0, ..., O 1_ap_i N 1_ap_i -1,m=0,…,O 2_ap_i N 2_ap_i -1.

[0060] For example, when rank=2, one spatial basis vector V is selected. l_ap_i As a broadband precoding method, the broadband precoding form is determined based on the antenna element configuration information (N1_ap_i, N2_ap_i). Subband precoding W 2_ap_i Through the phase difference between polarizations Quantization is performed using QPSK. Both transport layers use the same wideband precoding, and the subband precoding is mutually orthogonal. 1_ap_i W 2_ap_i V l_ap_i and U m_ap_i As shown in formulas (6), (7), (4) and (5) respectively.

[0061] In one exemplary embodiment, determining the feedback codebook based on the indication information includes: determining AP group configuration information of the extended antenna unit based on the first indication information; and determining the feedback codebook based on the second indication information and the AP group configuration information of the extended antenna unit.

[0062] In an exemplary embodiment, the AP group configuration information of the extended antenna element includes: a set of horizontal and vertical dimension parameter groups of the AP group of the extended antenna element {(N1_ap_1,N2_ap_1),...,(N1_ap_i,N2_ap_i),...,(N1_ap_Kg,N2_ap_Kg)}.

[0063] In an exemplary embodiment, the set of horizontal and vertical dimension parameter groups {(N1_ap_1,N2_ap_1),...,(N1_ap_i,N2_ap_i),...,(N1_ap_Kg,N2_ap_Kg)} of the AP group of the extended antenna elements is determined by the set of horizontal and vertical extension parameter groups {(Ms_ap_1,Ns_ap_1),...,(Ms_ap_i,Ns_ap_i),...,(Ms_ap_Kg,Ns_ap_Kg)} of the AP group of the extended antenna elements, the horizontal dimension N1_s of the basic antenna element, and the vertical dimension N2_s of the basic antenna element; wherein, N1_ap_i = Ms_ap_i * N1_s, N2_ap_i = Ns_ap_i * N2_s.

[0064] In an exemplary embodiment, the set of horizontal and vertical extension parameter groups {(Ms_ap_1,Ns_ap_1),...,(Ms_ap_i,Ns_ap_i),...,(Ms_ap_Kg,Ns_ap_Kg)} of the extended antenna element AP group is determined by the number of AP groups Kg of the extended antenna element, the horizontal dimension N1_s of the basic antenna element, and the vertical dimension N2_s of the basic antenna element.

[0065] In one embodiment, the number of ports Np of the basic antenna element is determined by the horizontal dimension N1_s and the vertical dimension N2_s of the basic antenna element, i.e., Np = 2 * N1_s * N2_s. The number of ports {Np_ap_1,...,Np_ap_i,...,Np_ap_Kg} of the extended antenna element's AP group is determined by the set of parameters {(N1_ap_1,N2_ap_1),...,(N1_ap_i,N2_ap_i),...,(N1_ap_Kg,N2_ap_Kg)} of the extended antenna element's AP group, i.e., Np_ap_i = 2 * N1_ap_i * N2_ap_i. Furthermore, this can be achieved by extending the set of parameters in the horizontal and vertical directions of the extended antenna element's AP group.

[0066] In an exemplary embodiment, when Kg is 2, N1_s is 2, and N2_s is 1, the value of {(Ms_ap_1,Ns_ap_1),(Ms_ap_2,Ns_ap_2)} includes at least one of the following: {(1,1),(2,1)}, {(1,1),(1,2)}, {(1,1),(3,1)}, {(1,1),(2,2)}, {(1,1),(4,1)}, {(1,1),(2,3)}, {(1,1),(3,2)}, {(1,1)(6,1)}, (3,1),(4,1)}, {(3,1),(2,3)}, {(1,1)(6,1)}, (3,1),(4,1)}, {(3,1),(2,3)}. ,2)};When Kg is 2, N1_s is 2, and N2_s is 1, the values ​​of {(N1_ap_1,N2_ap_1),(N1_ap_2,N2_ap_2)} include at least one of the following: {(2,1),(4,1)}, {(2,1),(2,2)}, {(2,1),(6,1)}, {(2,1),(4,2)}, {(2,1),(8,1)}, {(2,1),(4,3)}, {(2,1),(6,2)}, {(2,1)(12,1)}, (6,1),(8,1)}, {(6,1),(4,2)}.
