[0043] The current uplink 4-port codebook is limited by complexity and overhead and cannot be applied on a large scale, while the uplink 2-port codebook cannot meet the current uplink transmission throughput requirements.

[0044] The embodiments of the present disclosure provide an information processing method and apparatus, a communication device, a communication system, and a storage medium.

[0045] In a first aspect, an embodiment of the present disclosure provides an information processing method, which is executed by a terminal, and the method includes:

[0046] receiving first information sent by a network device, where the first information is used to indicate a first codeword in a codebook, where the codebook corresponds to the number of antenna ports used by the terminal to transmit uplink channels, and the number of antenna ports used by the terminal to transmit uplink channels is 3;

[0047] precoding the uplink channel according to the first codeword;

[0048] The precoded uplink channel is sent to the network device.

[0049] In the above embodiment, the 3-port terminal receives the first information sent by the network device to determine the first codeword configured for it by the network device, and then implements precoding of the uplink channel based on the first codeword, so that the uplink 3-port terminal can implement uplink transmission based on the codebook corresponding to the number of antenna ports being 3, effectively ensuring the uplink transmission throughput while avoiding the problems of excessive complexity and overhead.

[0050] In combination with some embodiments of the first aspect, the antenna port for transmitting the uplink channel of the terminal adopts a single-polarization arrangement.

[0051] In the above embodiment, by setting the three uplink antenna ports to a single-polarization arrangement, the terminal can effectively form a beam.

[0052] In combination with some embodiments of the first aspect, the codebook includes at least one of the following: codewords with a layer number of 1, codewords with a layer number of 2, and codewords with a layer number of 3.

[0053] In the above embodiment, configuring codewords of different layers in the codebook can effectively ensure the comprehensiveness of the codewords in the codebook, allowing the network device to configure more effective codewords according to the actual situation of the terminal, effectively ensuring the throughput of uplink transmission.

[0054] In combination with some embodiments of the first aspect, the codebook includes at least one of the following: a fully coherent codebook, a partially coherent codebook, and a non-coherent codebook.

[0055] In the above embodiment, by configuring a fully coherent codebook, a partially coherent codebook, and a non-coherent codebook, terminals of different coherence types can all reliably implement uplink transmission of three antenna ports, effectively ensuring the reliability of uplink transmission.

[0056] In conjunction with some embodiments of the first aspect, the codewords in the fully coherent codebook are determined based on a discrete Fourier transform (DFT) beam, and the DFT vector is expressed as:

[0057] Wherein, N1 represents the number of ports in the horizontal dimension and is equal to 3, O1 represents the number of oversampling in the horizontal dimension and is a pre-configured positive integer, l is an integer greater than or equal to zero, j represents the square root of -1, and the superscript T represents the transpose of the matrix.

[0058] In the above embodiment, the codewords in the fully coherent codebook are determined based on discrete Fourier transform. By utilizing the basic principle of the DFT codebook, orthogonality between layers of the 3-port fully coherent codebook can be effectively guaranteed, thereby ensuring the reliability of uplink transmission.

[0059] In combination with some embodiments of the first aspect, each layer of codewords in the fully coherent codebook includes mutually orthogonal DFT vectors.

[0060] In the above embodiment, by setting the codewords in the fully coherent codebook to mutually orthogonal DFT vectors in each layer, the reliability of the 3-port fully coherent uplink transmission can be effectively guaranteed.

[0061] In conjunction with some embodiments of the first aspect, the fully coherent codebook includes at least one of the following:

[0069] One of A3 and A4 is any one of the 2-port 2-layer fully coherent codewords, and the other is 1.

[0070] In the above embodiment, by setting some elements of the codewords in the partially coherent codebook to fully coherent codewords of two ports, it can be effectively ensured that the codewords in the codebook have two ports that are coherent, while the other port is irrelevant to the two ports, thereby ensuring the reliability of uplink partially coherent transmission.

[0071] In conjunction with some embodiments of the first aspect, the 2-port 1-layer fully coherent codeword includes at least one of the following:

[0072] In the above embodiment, a 3-port 1-layer or 3-port 2-layer codeword can be determined based on the above 2-port 1-layer fully coherent codeword, which can effectively reduce the complexity of codeword determination in the 3-port codebook.

[0162] In the related art, codebooks for uplink 2-port transmission and 4-port transmission are defined in uplink MIMO transmission. Although the 4-port codebook is defined, most commercial terminals currently only support 2-port transmission due to terminal limitations in complexity and overhead.

[0163] In some embodiments, to further improve uplink transmission throughput, the number of uplink transmission ports of the terminal can be further increased, for example, to 3 ports. However, in the related art, research on uplink 3-port transmission has not yet been conducted, and issues such as antenna arrangement, 3-port codebook, and 3-port SRS resources still require further study.

[0164] In some embodiments, a dual-polarized linear array is typically used in an uplink 4-port terminal, where port 0 and port 1 form a beam, and port 2 and port 3 form a beam. The uplink 4-port fully coherent codebook uses the R15 downlink Type I 4-port codebook, and the parameters of the codebook are restricted.

[0165] In some embodiments, when a terminal uses three ports, a dual-polarized antenna arrangement makes it difficult to form a beam, so a single-polarized antenna arrangement can be used. Optionally, as shown in FIG1b , the antenna azimuths of ports 0, 1, and 2 are consistent and are all in the horizontal dimension.

[0166] FIG2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to information processing and is used in a communication system 100. The method includes:

[0167] Step S2101: The terminal sends second information to the network device.

[0168] In some embodiments, the network device receives second information sent by the terminal.

[0169] In some embodiments, the number of antenna ports selected for the terminal to transmit uplink channels is 3. Optionally, antenna ports for the terminal to transmit uplink channels are arranged in a single-polarization manner.

[0170] In some embodiments, the second information is used to indicate the coherence type of the terminal. Optionally, the second information may also be used to instruct the network device to determine the first codeword. Optionally, the second information is used to instruct the network device to determine the first codeword based on the coherence type of the terminal. Optionally, the coherence type may be used by the network device to determine the first codeword. Optionally, the first codeword may be used by the terminal to precode an uplink channel. Optionally, the uplink channel may be, for example, a physical uplink shared channel (PUSCH).

[0171] In some embodiments, the coherence type of a terminal can be any one of the following: a fully coherent type, a partially coherent type, and an incoherent type. Optionally, the coherence type of a fully coherent terminal is a fully coherent type. Optionally, the coherence type of a partially coherent terminal is a fully coherent type. Optionally, the coherence type of an incoherent terminal is an incoherent type.

[0172] Step S2102: The network device determines the first codeword in the codebook.

[0173] In some embodiments, the codebook is a codebook corresponding to the number of antenna ports used by the terminal to transmit uplink channels. For example, the codebook is a codebook corresponding to 3 antenna ports.

[0174] In some embodiments, the codebook corresponding to the number of antenna ports for transmitting uplink channels being equal to 3 includes at least one of the following: codewords of layer 1, codewords of layer 2, and codewords of layer 3.

[0175] In some embodiments, a "codeword" may also be referred to as a "precoding matrix." Optionally, the number of layers of a codeword may also refer to the rank of the precoding matrix. Optionally, the codebook may include at least one of the following: a rank-1 precoding matrix, a rank-2 precoding matrix, or a rank-3 precoding matrix.

[0176] In some embodiments, the codebook corresponding to the number of antenna ports for transmitting uplink channels being equal to 3 includes at least one of the following: a fully coherent codebook, a partially coherent codebook, and a non-coherent codebook.

[0177] For example, the codebook corresponding to the number of antenna ports being 3 may include only a fully coherent codebook, and the fully coherent codebook only includes codewords of layer 1. Alternatively, the codebook corresponding to the number of antenna ports being 3 may include a fully coherent codebook and a partially coherent codebook, the fully coherent codebook including codewords of layers 1 to 3, and the partially coherent codebook including only codewords of layers 1 and 2. Alternatively, the codebook corresponding to the number of antenna ports being 3 may include a fully coherent codebook, a partially coherent codebook, and a non-coherent codebook, each of which includes codewords of layers 1 to 3.

[0178] In some embodiments, a fully coherent codebook may also be referred to as a codeword set for fully coherent transmission. Alternatively, a partially coherent codebook may also be referred to as a codeword set for partially coherent transmission. Alternatively, a non-coherent codebook may also be referred to as a codeword set for non-coherent transmission.

[0179] It is understandable that a terminal may not calibrate all antenna ports to enable coherent transmission. Related technologies define the following three types of terminal antenna coherent transmission capabilities: Full Coherence: All antenna ports of the terminal can transmit coherently; Partial Coherence: Antenna ports within the same coherent transmission group of the terminal can transmit coherently, but antenna ports in different coherent transmission groups cannot transmit coherently; Incoherence: No antenna port of the terminal device can transmit coherently.

[0180] In some embodiments, the network device may determine the first codeword based on the coherence type of the terminal. Alternatively, the network device may determine the first codeword based on other information, such as the modulation capability of the terminal or a reference signal sent by the terminal, etc., which is not limited in the embodiments of the present disclosure.

[0181] In some embodiments, the coherence type of the terminal is a fully coherent type, and the first codeword is a codeword in a fully coherent codebook, or the first codeword is a codeword in any one of the following: a fully coherent codebook, a partially coherent codebook, and an incoherent codebook; and / or the coherence type of the terminal is a partially coherent type, and the first codeword is a codeword in a partially coherent codebook, or the first codeword is a codeword in any one of the following: a partially coherent codebook and an incoherent codebook; and / or the coherence type of the terminal is an incoherent type, and the first codeword is a codeword in an incoherent codebook.

[0182] Optionally, if the network device determines that the coherence type of the terminal is a fully coherent type, the first codeword may be determined from a fully coherent codebook. Optionally, if the network device determines that the coherence type of the terminal is a partially coherent type, the first codeword may be determined from a partially coherent codebook. Optionally, if the network device determines that the coherence type of the terminal is an incoherent type, the first codeword may be determined from an incoherent codebook.

[0183] Optionally, if the network device determines that the coherence type of the terminal is a fully coherent type, the first codeword may be determined from a fully coherent codebook, a partially coherent codebook, or an incoherent codebook. Optionally, if the network device determines that the coherence type of the terminal is a partially coherent type, the first codeword may be determined from a partially coherent codebook or an incoherent codebook. Optionally, if the network device determines that the coherence type of the terminal is an incoherent type, the first codeword may be determined from an incoherent codebook.

[0184] In some embodiments, the network device may first determine a first codebook corresponding to the coherence type of the terminal based on the coherence type of the terminal. For example, if the coherence type of the terminal is fully coherent, the first codebook may include one or more of a fully coherent codebook, a non-coherent codebook, and a partially coherent codebook, or the first codebook may only include a fully coherent codebook. Furthermore, the network device may select a codeword from the first codebook as the first codeword.

[0185] In some embodiments, the network device may receive a reference signal sent by the terminal, such as a sounding reference signal (SRS), and obtain channel state information based on the reference signal to obtain an optimal first codeword.

[0186] In some embodiments, the codewords in the fully coherent codebook are determined based on a discrete Fourier transform (DFT) beam, where the DFT vector is represented as: Wherein, N1 represents the number of ports in the horizontal dimension and is equal to 3, O1 represents the oversampling number in the horizontal dimension and is a preconfigured positive integer, l is an integer greater than or equal to zero, j represents the square root of -1, the superscript T represents the transpose of the matrix, and e is a natural constant.

[0187] Alternatively, a DFT vector may also be referred to as a DFT beam. Alternatively, a DFT beam may be represented as a DFT vector.

[0188] Optionally, the value of O1 can be 1, 2, 3, or 4, etc., which is not limited in the embodiment of the present disclosure. Optionally, the value of l can be any one of 0, 1, 2...N1O1-1.

[0189] In some embodiments, each layer of codewords in the fully coherent codebook is a mutually orthogonal DFT vector.

[0190] It is worth noting that, referring to the above embodiment, a DFT vector can be represented as a matrix with one layer, that is, a matrix with only one column. The codewords in the fully coherent codebook can be matrices with one, two, or three layers, where each layer can be represented as a DFT vector, and the DFT vectors represented by each column can be orthogonal to each other.

[0191] For example, the fully coherent codebook may include the codeword: The codeword includes two layers, each layer of which is a DFT vector. If O1 is equal to 1 and N1 is equal to 3, the first layer is the DFT vector corresponding to l equal to 0, and the second layer is the DFT vector corresponding to l equal to 1. The DFT vectors of the two layers are orthogonal to each other.

[0192] In some embodiments, the fully coherent codebook includes at least one of the following:

[0193] as well as,

[0194] Where W represents the codeword in the codebook, the superscript of W represents the number of layers of the corresponding codeword, i 1,1 =0,1,…,N1O1-1, P=N1N2 represents the total number of ports and is equal to 3.

[0195] For example, if the fully coherent codebook only includes codewords with a layer number of 1, then the fully coherent codebook may only include If the fully coherent codebook includes only codewords with a layer number of 2, then the fully coherent codebook can include The corresponding codeword, and / or, The corresponding codeword.

[0196] In one embodiment, the fully coherent codebook includes codewords of layers 1 to 3. When the horizontal dimension oversampling number O1 is set to 1, the fully coherent codebook can be as shown in Table 1 below:

[0197] Table 1

[0198] Wherein, Rank represents the number of layers of the corresponding codeword, that is, the rank of the corresponding precoding matrix. As shown in Table 1, the fully coherent codebook includes multiple codewords with a layer number of 1, multiple codewords with a layer number of 2, and a codeword with a layer number of 3.

[0199] In some embodiments, the partially coherent codebook may be determined based on a 2-port 1-layer fully coherent codeword and / or a 2-port 2-layer fully coherent codeword.

[0200] In some embodiments, the partially coherent codebook includes at least one of the following:

[0201] Where W represents the codeword in the codebook, and the superscript of W represents the number of layers of the corresponding codeword;

[0202] A0 is any one of the fully coherent codewords of 2 ports and 1 layer;

[0203] One of A1 and A2 is any one of the fully coherent codewords of 2 ports and 1 layer, and the other is 1; or one of A1 and A2 is any one of the fully coherent codewords of 2 ports and 1 layer, and the other is 0;

[0204] One of A3 and A4 is any one of the 2-port 2-layer fully coherent codewords, and the other is 1.

[0205] Optionally, the 2-port 1-layer fully coherent codeword includes at least one of the following:

[0206] Optionally, the 2-port 2-layer fully coherent codeword includes at least one of the following:

[0207] For example, if the partially coherent codebook only includes codewords with a layer number of 1, the partially coherent codebook may only include If the partially coherent codebook includes only codewords with a layer number of 2, the fully coherent codebook can include The corresponding codeword.

[0208] In one embodiment, the partially coherent codebook includes codewords of layers 1 to 3. The sparse matrix of the codewords in the partially coherent codebook may be as shown in Table 2 below:

[0209] Table 2

[0210] Among them, the 1 in the sparse matrix of the codeword in the partially coherent codebook in Table 2 can be, for example, 1, -1, j or -j, which are not listed one by one in the embodiment of the present disclosure. For example, the sparse matrix of a codeword in the partially coherent codebook is For example, if the fully coherent codeword of 2 ports and 1 layer corresponding to A0 is The code word can be

[0211] In some embodiments, the codewords in the non-coherent codebook are a first matrix, the first matrix selects only one antenna port in each layer, and the antenna ports selected in each layer are different. Optionally, the first matrix can be an antenna selection matrix or an antenna selection vector.

[0212] In some embodiments, the non-coherent codebook may include codewords corresponding to at least one of layers 1 to 3. For example, the non-coherent codebook may include only codewords of layer 1, or may include codewords of layers 1 and 2, and so on.

[0213] In some embodiments, the non-coherent codebook includes codewords corresponding to each of the layers 1 to 3. Referring to Table 3 below, the non-coherent codebook may be as follows:

[0214] Table 3

[0215] Refer to Table 3, with codeword For example, in the first layer, that is, the first column of the matrix, the first antenna port is selected; in the second layer, that is, the second column of the matrix, the second antenna port is selected.

[0216] In some embodiments, the codewords in the partially coherent codebook and the codewords in the incoherent codebook may also be determined based on a normalization coefficient. For example, the normalization coefficient may be multiplied by a matrix designed as shown in Table 2 or Table 3 to obtain the corresponding codeword. Alternatively, the normalization coefficient may be obtained based on actual measurements, and the present embodiment does not limit its value. Alternatively, the normalization coefficient may be equal to Where M is the number of non-zero elements in the corresponding matrix.

[0217] For example, the matrix in Table 3 For example, the normalization coefficient corresponding to the matrix can be Then we can get a codeword in the non-coherent codebook as

[0218] For another example, take the matrix in Table 2 For example, the normalization coefficient corresponding to the matrix can be Then we can get a codeword in the partially coherent codebook as

[0219] Step S2103: The network device sends first information to the terminal.

[0220] In some embodiments, the terminal receives first information sent by the network device. Optionally, the first information is used to instruct the terminal to precode an uplink channel.

[0221] In some embodiments, the first information is used to indicate a first codeword in a codebook. Optionally, the first codeword is used by the terminal to precode an uplink channel.

[0222] In some embodiments, the first information may be, for example, a Transmission Precoding Matrix Indicator (TPMI). For example, the network device may notify the terminal of the precoding matrix used for actual transmission, that is, the first codeword, and notify the terminal of the number of transmission layers through a Rank Indicator (RI).

[0223] Step S2104: The terminal precodes the uplink channel according to the first codeword.

[0224] In some embodiments, the terminal can determine the corresponding first codeword from the codebook according to the first information sent by the network device. Then, the terminal can use the determined first codeword to perform precoding processing on the uplink channel to complete the transmission of the uplink channel.

[0225] Optionally, precoding the uplink channel may specifically refer to precoding data transmitted in the uplink channel. For example, precoding data transmitted in a physical uplink shared channel may be performed.

[0226] Step S2105: The terminal sends the precoded uplink channel to the network device.

[0227] In some embodiments, the network device receives a precoded uplink channel sent by the terminal. Alternatively, the network device receives a precoded uplink channel sent by the terminal using a first codeword.

[0228] In some embodiments, after the terminal uses the first codeword to perform precoding processing on the uplink channel, the terminal can map the precoded data to the corresponding antenna port and send the precoded uplink channel to the network device.
