Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communications, in particular to a method for information feedback and indication. BACKGROUND

[0002] Distributed Multiple-Input Multiple-Output (Distributed MIMO), Cell-Free Massive Multiple-Input Multiple-Output (CF-MIMO) as a potential key technology point of B5G / 6G multi-antenna direction gets more and more attention. One of the significant features of this technology is that the spatial distribution of Access Points (APs) in a given area is more dispersed than the centralized APs used in the current NR, and the number of APs is more than the number of User Equipments (UEs), and multiple APs simultaneously serve multiple UEs.

[0003] In New Radio (NR), Channel State Information Reference Signal (CSI-RS) can be used for downlink CSI measurement and feedback. The complete CSI measurement and feedback procedure at UE side includes: UE receives CSI-RS configuration information, UE measures CSI-RS transmitted by BS based on CSI-RS configuration information, UE performs downlink CSI feedback based on the measurement result of CSI-RS. The specific time-frequency resource of BS transmitting CSI-RS is called CSI-RS resource. The logical antenna port carrying the CSI-RS resource is called CSI-RS port. The number of CSI-RS ports supported in NR is {1, 2, 4, 8, 12, 16, 24, 32}. When the number of CSI-RS ports is not less than 4, the parameters of the horizontal and vertical dimensions of the 2D antenna panel are determined by N1 and N2 respectively; currently only limited N1 / N2 combinations are supported for a given CSI-RS port. The configurable parameters of CSI-RS resource include CSI-RS port, density, periodicity and offset, code division type, power control offset, quasi co-location, etc. In order to ensure the flexibility of CSI-RS measurement, in NR, CSI-RS resource is configured in two levels, namely CSI-RS resource set and CSI-RS resource setting. Among them, the CSI-RS resource set is composed of one or more CSI-RS resources, and the CSI-RS resource setting is composed of one or more CSI-RS resource sets. The time domain characteristic parameters (periodic, semi-persistent, aperiodic) of CSI-RS resource are configured on the CSI-RS resource setting, and the remaining parameters are configured on the CSI-RS resource set. Different CSI-RS resources in the same CSI-RS resource set have the same CSI-RS port and density. The codebook-based CSI feedback supports codebook types including "typeISinglePanel", "typeIMulti-Panel", "typeII", "typeII-r16", etc.

[0004] In potential application scenarios of future-oriented CF-MIMO, such as large stadiums, shopping malls, airports, and automated factories, on the one hand, the spatial distribution of UEs will become very complex, and there will be some areas with dense and large number of UEs and some areas with sparse and small number of UEs; on the other hand, the quality of service requirements of UEs at different spatial positions can be quite different, some UEs have very high capacity requirements such as extended reality (XR) devices, and some UEs have very high requirements for latency such as industrial automation devices. In addition, with the exponential increase in the scale of network nodes, the operating cost and energy consumption are also an important challenge. To solve the above problems, a heterogeneous large-scale distributed network composed of distributed units with different antenna scales can be used, and a flexible joint coherent transmission scheme can be used to meet various business requirements. However, the above scheme is not supported in the prior art. SUMMARY

[0022] In the present embodiment, a method of information feedback running on the above computer terminal is provided, Figure 2 is a flowchart of the method of information feedback according to embodiments of the present application, which is applied to a terminal, such as Figure 2 as shown, and the flowchart includes the following steps:

[0023] In step S202, indication information for channel state information reference signal (CSI-RS) measurement is received, and a feedback codebook is determined according to the indication information, and channel state information feedback is performed using the feedback codebook.

[0024] In one example embodiment, the indication information includes at least one of the following: first indication information for indicating parameters of basic antenna elements and extended antenna elements; and second indication information for determining a feedback codebook of the extended antenna elements.

[0025] ​In an example embodiment, the first indication information comprises at least one of: a horizontal direction dimension N1_s of the basic antenna unit; a vertical direction dimension N2_s of the basic antenna unit; a number Kg of access point (AP) groups of the extended antenna unit; a set of horizontal direction and vertical direction extension parameter groups {(Ms_ap_1, Ns_ap_1),..., (Ms_ap_i, Ns_ap_i),..., (Ms_ap_Kg, Ns_ap_Kg)} of the AP groups of the extended antenna unit; wherein N1_s takes a value of 2, 3, 4, 6 or 8, N2_s takes a value of 1 or 2, Kg takes a value of 2, 3 or 4, i takes a value of a positive integer not more than Kg, Ms_ap_i takes a value of 1, 2, 3, 4 or 6, Ns_ap_i takes a value of 1, 2, 3 or 4, and Np_ap_i takes a value of 4, 8, 12, 16, 24 or 32.

[0026] In an example embodiment, as shown in Table 1, the (N1_s, N2_s) of the basic antenna unit takes a value of a configuration with a port number not more than 16, and the (N1_ap_i, N2_ap_i) of the extended antenna unit takes a value of all configurations with a port number not more than 32. However, the extended antenna unit is composed of the basic antenna unit, and thus there is a constraint relationship between the configurations of the two. In addition, the number of resources in a set is not more than 8, the number of groups is not more than 4, and each group has at least one resource, further constraining the configuration possibilities. All embodiments of the present application are based on Table 1.

[0027] Table 1

[0028]

[0029]

[0030] In an example embodiment, the generation manner of the extended antenna unit comprises at least one of: generating the extended antenna unit by extending the basic antenna unit in the horizontal direction; generating the extended antenna unit by extending the basic antenna unit in the vertical direction; and generating the extended antenna unit by simultaneously extending the basic antenna unit in the horizontal direction and the vertical direction.

[0031] In one embodiment, the basic antenna unit is a dual-polarized uniform planar array (UPA) or a uniform linear array (ULA). The extended antenna unit is composed of multiple groups of basic antennas, so it is a heterogeneous antenna unit composed of multiple groups of UPA or ULA. The way of composing the extended antenna unit by the basic antenna unit includes: extending in the horizontal direction, extending in the vertical direction, and extending in the horizontal direction and the vertical direction at the same time. Extending in the horizontal direction means extending the multiple basic antenna units in rows as a whole and keeping the columns unchanged; extending in the vertical direction means extending the multiple basic antenna units in columns as a whole and keeping the rows unchanged; extending in the horizontal direction and the vertical direction at the same time means extending the multiple basic antenna units in columns as a whole and in rows at the same time.

[0032] In one example embodiment, the basic antenna unit and the extended antenna unit are configured in a CSI-RS resource set, one CSI-RS resource set includes Kg groups of CSI-RS resources, one group of CSI-RS resources includes Kr_i CSI-RS resources, the number of CSI-RS resources in one CSI-RS resource set is Ks, each CSI-RS resource in one CSI-RS resource set corresponds to one basic antenna unit, each group of CSI-RS resources corresponds to one access point (AP) group of the extended antenna unit, the number of ports of one CSI-RS resource is Np, and the number of ports of one group of CSI-RS resources is Np_ap_i; wherein, the value of Kr_i is a positive integer less than or equal to 7, the value of Ks is 2, 3, 4, 5, 6, 7 or 8, the value of 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 related protocol stipulates that each CSI-RS resource (CSI-RS resource) in a CSI-RS resource set has the same antenna parameter configuration. Under the premise of not changing the existing CSI-RS configuration framework, in order to support joint coherent transmission of antenna units of different sizes in the embodiment of the application, different CSI-RS resource groups are constructed in one CSI-RS resource set, and each CSI-RS resource group corresponds to one AP group. The CSI-RS resource of each AP group is defined as a basic antenna unit. All CSI-RS resource groups constitute an extended antenna unit.

[0034] In an example embodiment, the second indication information comprises at least one of: a type of the feedback codebook; an AP group wideband precoding selection manner of the extended antenna unit; an AP group subband precoding selection manner of the extended antenna unit.

[0035] In an example embodiment, the AP group wideband precoding selection manner of the extended antenna unit comprises independent selection or joint selection.

[0036] In an example embodiment, the AP group subband precoding selection manner of the extended antenna unit comprises independent selection or joint selection.

[0037] In an example embodiment, when the AP group wideband precoding selection manner of the extended antenna unit is independent selection, each AP group independently selects a wideband precoding.

[0038] In an example embodiment, when the AP group wideband precoding selection manner of the extended antenna unit is joint selection, when all AP groups in the extended antenna unit have completely different antenna configurations, each AP group independently selects a wideband precoding, when part of the AP groups in the extended antenna unit have the same antenna configuration, the AP groups with the same antenna configuration have the same wideband precoding selection manner, and the AP groups with different antenna configurations independently select a wideband precoding.

[0039] In an example embodiment, when the AP group subband precoding selection manner of the extended antenna unit is independent selection, each AP group independently selects a subband precoding.

[0040] In an example embodiment, when the AP group subband precoding selection manner of the extended antenna unit is joint selection, when all AP groups in the extended antenna unit have completely different antenna configurations, each AP group independently selects a subband precoding, when part of the AP groups in the extended antenna unit have the same antenna configuration, the AP groups with the same antenna configuration have the same subband precoding selection manner, and the AP groups with different antenna configurations independently select a subband precoding.

[0041] In an embodiment, determining the extended antenna unit codebook based on the typeISinglePanel codebook type comprises the following flow:

[0042] In step S2021, the horizontal direction and vertical direction oversampling factor set {(O1_ap_1, O2_ap_1),..., (O1_ap_i, O2_ap_i),..., (O1_ap_Kg, O2_ap_Kg)} of the AP groups of the extended antenna unit is determined according to the configuration information of the AP groups of the extended antenna unit.

[0043] Step S2022, according to the wideband precoding selection mode of the AP group of the extended antenna unit, the configuration information and the horizontal direction and vertical direction oversampling factor set, determine the wideband precoding W1 = [W 1_ap_1 ,…,W 1_ap_i ,…,W 1_ap_Kg ] of the AP group of the extended antenna unit.

[0044] In the case of the wideband precoding selection mode of the AP group of the extended antenna unit being configured as AP group independent selection, then no matter whether the configuration information of the AP group exists partially same, each AP in the AP group of the extended antenna unit independently selects a wideband precoding.

[0045] For example, in the case of the wideband precoding selection mode of the AP group of the extended antenna unit being configured as AP group independent rotation, the configuration information of the AP group of the extended antenna unit {(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 independently selects a wideband precoding;

[0046] The configuration information of the AP group of the extended antenna unit {(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 independently selects a wideband precoding.

[0047] In the case of the wideband precoding selection mode of the AP group of the extended antenna unit being configured as AP group joint selection, when the antenna configuration of each AP in the configuration information of the AP group is completely different, each AP in the AP group of the extended antenna unit independently selects a wideband precoding; when the antenna configuration of the AP in the configuration information of the AP group is completely same, then in the AP group of the extended antenna unit, multiple APs with the same configuration jointly select the same wideband precoding, and multiple APs with different configurations independently select a wideband precoding.

[0048] For example, in the case of the wideband precoding selection mode of the AP group of the extended antenna unit being configured as AP group joint selection, the configuration information of the AP group of the extended antenna unit {(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 independently selects a wideband precoding.

[0049] The configuration information of the AP group of the extended antenna unit {(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 The W 1_ap_2 A wideband precoding is selected jointly. 1_ap_1 The W 1_ap_3 The W 1_ap_4 A wideband precoding is selected independently.

[0050] Step S2023, according to the sub-band precoding selection mode of the AP group of the extended antenna unit, the configuration information, and the horizontal direction and vertical direction oversampling factor set, the sub-band precoding W2 = [W 2_ap_1 ,…, W 2_ap_i ,…, W 2_ap_Kg ] of the AP group of the extended antenna unit is determined.

[0051] In the case where the sub-band precoding selection mode of the AP group of the extended antenna unit is configured as AP group independent selection, no matter whether the configuration information of the AP group exists partially same, each AP in the AP group of the extended antenna unit independently selects the sub-band precoding.

[0052] For example, in the case where the sub-band precoding selection mode of the AP group of the extended antenna unit is configured as AP group independent rotation, the configuration information of the AP group of the extended antenna unit {(N1_ap_1, N2_ap_1), (N1_ap_2, N2_ap_2)} = {(2, 1), (4, 2)}, then W 2_ap_1 The W 2_ap_2 A sub-band precoding is selected independently.

[0053] The configuration information of the AP group of the extended antenna unit {(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 The W 2_ap_2 The W 2_ap_3 A sub-band precoding is selected independently.

[0054] In the case that the sub-band precoding selection mode of the AP group of the extended antenna unit is configured as AP group joint selection, when the antenna configuration of each AP in the configuration information of the AP group is completely different, each AP in the AP group of the extended antenna unit independently selects a sub-band precoding; when the antenna configuration of the AP in the configuration information of the AP group is completely the same, the APs with the same configuration in the AP group of the extended antenna unit jointly select the same sub-band precoding, the APs with the same configuration jointly select the same sub-band precoding, and the APs with different configurations independently select sub-band precodings.

[0055] For example, in the case that the sub-band precoding selection mode of the AP group of the extended antenna unit is configured as AP group joint selection, the configuration information of the AP group of the extended antenna unit {(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 selects a sub-band precoding; the configuration information of the AP group of the extended antenna unit {(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)}, W 2_ap_1 and W 2_ap_2 jointly select a sub-band precoding, W 2_ap_3 and W 2_ap_4 jointly select a sub-band precoding, W 2_ap_1 , W 2_ap_3 independently selects a sub-band precoding.

[0056] In step S2024, the wideband precoding and the sub-band precoding of the AP group of the extended antenna unit determine the feedback codebook W as shown in formula (1).

[0057]

[0058] Specifically, the feedback codebook W of the AP group of the extended antenna unit is spliced by the sub-codebooks of the Kg APs in order. Whether the sub-codebooks of different APs in the AP group of the extended antenna unit are jointly fed back further reduces the feedback overhead, which is determined according to the schemes described in steps S2021 to S2024. γ is a power normalization factor, which ensures that the modulus of each column of W is 1. The sub-codebook of AP i in the AP group of the extended antenna unit is jointly determined by the wideband precoding W 1_ap_i and the sub-band precoding W 2_ap_i .

[0059] For example, for dual-polarized UPA, at rank = 1, 1 spatial basis vector V l_ap_i As wideband precoding, the wideband precoding form is determined according to the configuration information (N1_ap_i, N2_ap_i) of the antenna elements. The subband precoding W 2_ap_i Through inter-polarization phase difference Quantized using QPSK. W 1_ap_i , W 2_ap_i , V l_ap_i and U m_ap_i are shown in equations (2), (3), (4) and (5) respectively.

[0060]

[0061] where l = 0, …, O 1_ap_i N 1_ap_i - 1, m = 0, …, O 2_ap_i N 2_ap_i - 1.

[0062] For example, at rank = 2, 1 spatial basis vector V l_ap_i As wideband precoding, the wideband precoding form is determined according to the configuration information (N1_ap_i, N2_ap_i) of the antenna elements. The subband precoding W 2_ap_i Through inter-polarization phase difference Quantized using QPSK. Two transmission layers use the same wideband precoding, and the subband precodings are orthogonal to each other. W 1_ap_i , W 2_ap_i , V l_ap_i and U m_ap_i are shown in equations (6), (7), (4) and (5) respectively.

[0063]

[0064] In one example embodiment, determining the feedback codebook according to the indication information comprises: determining the AP group configuration information of the extended antenna elements according to the first indication information; and determining the feedback codebook according to the second indication information and the AP group configuration information of the extended antenna elements.

[0065] In one example embodiment, the AP group configuration information of the extended antenna elements comprises: a set of horizontal direction dimension and vertical direction dimension parameter groups {(N1_ap_1, N2_ap_1), …, (N1_ap_i, N2_ap_i), …, (N1_ap_Kg, N2_ap_Kg)} of the AP groups of the extended antenna elements.

[0066] 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.

[0067] 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.

[0068] 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.
