Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to an uplink transmission method and device, a terminal and a BSC receiving device. BACKGROUND

[0002] In a backscatter (BSC) hardware design, a BSC system can have a passive radio frequency component or a semi-passive radio frequency component. The BSC system includes the following parts: a BSC transmitter or a backscatter communication terminal (BSC UE), a BSC receiver. Taking a passive terminal as an example, the passive BSC UE collects the energy of the radio frequency signal in the environment, and loads the information to be sent to the signal in the environment to send to the receiver, so as to realize the communication between the passive BSC UE and the receiver.

[0003] The BSC UE can transmit uplink signals through multi-antenna technology to obtain multi-antenna processing gain. The physical uplink shared channel (PUSCH) of the New Radio (NR) system supports two uplink transmission schemes of codebook-based transmission and non-codebook transmission. In the traditional codebook-based uplink transmission scheme, the NR system supports using the codebook of the Discrete Fourier Transform spread Orthogonal frequency division multiplex (DFT-S-OFDM) waveform and the Cyclic Prefix (CP)-OFDM waveform, however, the precoding design of the BSC UE is limited by factors such as hardware, power consumption and transmission mode, and there are problems such as low transmission rate and weak coverage ability in long-distance transmission. If the signal is transmitted according to the traditional uplink transmission method, the signal will be severely distorted and greatly faded, resulting in a large bit error rate and detection difficulty, so the traditional uplink transmission scheme is not suitable for signal modulation of the BSC UE.

[0050] In the description of the embodiments of the present application, first, some concepts used in the following description are explained.

[0051] I. Backscatter communication:

[0052] The BSC system includes the following parts: Backscatter Transmitter / BSC UE, Backscatter Receiver. Taking the BSC UE as an example, its structure is shown in Figure 2 The BSC system utilizes the radio frequency signals in the environment, such as signals from cellular, television broadcast and WiFi, the BSC UE collects the energy thereof, and loads the information to be sent to the signals in the environment to send to the BSC receiver, so as to realize the communication between the passive BSC UE and the BSC receiver. The BSC UE of the BSC serves as a passive device in the BSC system, mainly composed of a radio frequency energy collector, a switch, a modulation module and an information decoder. The BSC UE receives the radio frequency source signals in the environment and obtains energy therefrom, which is stored in the energy collector to provide energy for the signal processing and signal transmission hardware modules of the BSC UE. Subsequently, the received signals are modulated and transmitted through the transmitting antenna to the BSC receiver.

[0053] Specifically, in order to send the information bits stored in the memory to the BSC receiver, the BSC UE changes the amplitude and phase of the backscatter signal by controlling the switching of the load impedance, so as to realize the modulation of the received carrier in the environment, and finally the BSC receiver can receive and decode the backscatter signal.

[0054] Define the reflection coefficient as Γ, the impedance of each antenna of the BSC UE is Z A , the i-th load impedance is Z i , and the following can be obtained:

[0055]

[0056]

[0057] Where θ A and θ i represent the phases of the antenna and the i-th load impedance, respectively. Assuming that the BSC UE has M antennas (M≥2) and N load impedances, and the antenna impedance of each antenna is equal, then the i-th load impedance Z i The corresponding reflection coefficient Γ i is defined as follows:

[0058]

[0059]

[0060]

[0061] From the above formula, it can be seen that the amplitude and phase of the reflection coefficient are greatly related to the selection of the load impedance, and further, it can be seen that the amplitude and phase of the load impedance affect the amplitude and phase of the reflection coefficient.

[0062] II. Precoding technology:

[0063] In the 5G communication system, one base station serves multiple users, and there is serious inter-user interference and intra-user data stream interference. Although by increasing the number of antennas at the base station end, the interference can be suppressed to a certain extent and the system capacity can be improved, but the system performance improvement is limited. In order to suppress inter-user interference, improve system capacity and simplify the design cost of the user end, the base station adopts precoding technology in the downlink.

[0064] Before 5G NR, due to the small number of base station antennas, full-digital precoding is realized by configuring one radio frequency link for each antenna, which can greatly improve the spectral efficiency of the system. However, in a multi-antenna system, the base station will configure a large number of antennas, and if one radio frequency link is configured for each antenna, a large number of radio frequency links and digital-to-analog converters will be required, which will lead to a sharp rise in system power consumption and hardware complexity. Hybrid precoding, as one of the key technologies to improve the spectral efficiency of multi-antenna systems, realizes beamforming through a two-stage shaping structure with digital and analog hybrid. Compared with full-digital precoding, hybrid precoding can guarantee the spectral efficiency of the system while reducing hardware power consumption and cost by reducing the configuration of radio frequency links and other hardware, making it possible to apply large-scale antennas to 5G systems and the next generation of mobile communication systems. Hybrid precoding is divided into baseband precoding and analog precoding: for digital precoding, at least one radio frequency link is required for each data stream to be transmitted; for analog precoding, each radio frequency link can be connected to multiple antennas and only responsible for phase modulation without changing the modulus of the signal.

[0065] The NR standard supports up to 4 layers of uplink (i.e. PUSCH) multi-antenna precoding, and if the uplink transmission adopts DFT precoding OFDM technology, it can only support single-layer transmission. The terminal can configure two modes for PUSCH multi-antenna precoding: one is based on codebook transmission, and the other is based on non-codebook transmission.

[0066] One limitation of uplink multi-antenna transmission is how much the terminal can control the correlation between antennas, or how much the relative phase between the signals transmitted by the two antennas of the terminal can be controlled by the terminal. Generally speaking, when doing multi-antenna precoding, the weights of each antenna port need to be accurately adjusted, which includes a specific phase shift. These weights will be applied to the signals transmitted by different antenna ports.

[0067] It is difficult to implement the transmission and reception of the BSC UE using the omnidirectional antenna, and the beam management of the backscatter needs to be considered to enhance the coverage performance. In the initial beam establishment of the NR system, the network side transmits a plurality of synchronization signal blocks (SSB), and the SSBs are transmitted in sequence and each SSB is carried on a different downlink beam. On the one hand, the SSB is associated with the downlink beam, and on the other hand, the SSB is also associated with the uplink random access occasion, the preamble and the like resources, so that the network side can learn the downlink beam selected by the terminal through the random access channel (RACH), thereby establishing the initial beam pair. In the subsequent communication process, the terminal assumes that the downlink transmission of the network side always uses the same spatial filter, that is, the network side always maintains the transmission beam used by the SSB. The network side also assumes that the uplink transmission of the terminal always uses the same spatial filter, that is, the terminal always maintains the transmission beam used in the RACH, and therefore the network side considers that the subsequent uplink reception can use the optimal reception beam used in the random access process.

[0068] The uplink transmission method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0069] As shown in the Figure 3 , the present application provides an uplink transmission method, comprising:

[0070] Step 301, the backscattering BSC terminal receives the connection related information of the antenna and the load impedance sent by the first BSC receiving device, and the connection related information comprises: precoding matrix information and / or signal modulation information.

[0071] In this embodiment, the first BSC receiving device is, for example: a BSC receiver, a base station, or a terminal with the same hardware structure as the first BSC receiving device, etc. The connection related information is the related information of the connection mode of the antenna and the load impedance of the BSC UE.

[0072] The first BSC receiving device can determine the precoding matrix information and / or signal modulation information according to the pilot sequence sent by the BSC terminal. The precoding matrix information and / or signal modulation information can indicate the connection mode of the antenna and the load impedance, the grouping condition of the load impedance, etc.

[0073] Optionally, the method further comprises: receiving transmission related information sent by the first BSC receiving device; the transmission related information comprises: channel coding mode and / or code rate. That is, the first BSC receiving device sends the BSC UE the information related to channel coding mode (such as service channel, control channel, etc.), code rate, etc.

[0074] Step 302: The BSC terminal processes the information bits according to the connection related information, and obtains to-be-sent data.

[0075] Optionally, the processing of the information bits by the BSC terminal comprises: pre-encoding the information bits and / or modulating the information bits, to obtain the to-be-sent data, which is the data that the BSC terminal needs to perform uplink transmission.

[0076] Step 303: The BSC terminal sends the to-be-sent data.

[0077] The BSC terminal selects a corresponding antenna and load impedance connection scheme to send the to-be-sent data according to the received connection related information.

[0078] Optionally, the sending of the to-be-sent data comprises: sending the to-be-sent data to the first BSC receiving device; and / or, sending the to-be-sent data to a second BSC receiving device, which is different from the first BSC receiving device.

[0079] In this embodiment, the first BSC receiving device can be a BSC Receiver, and the second BSC receiving device can be a backscatter transceiver (BSC Transceiver). The BSC terminal can send the to-be-sent data to the first BSC receiving device, or send the to-be-sent data to a second BSC receiving device, which is other than the first BSC receiving device, such as a radio frequency source.

[0080] Embodiments of the present application consider modulation information and / or pre-encoding matrix information based on the hardware architecture, modulation mode and pre-encoding design of BSC. The pre-encoding matrix information and / or signal modulation information can indicate the connection mode of the antenna and the load impedance. The BSC UE, based on the connection of the antenna and the load impedance, jointly controls the phase change of different reflection coefficients when performing uplink transmission, further determines the uplink transmission scheme, and can avoid or reduce the problems of signal distortion and signal fading caused by the existing uplink transmission mode, and reduce the bit error rate and signal detection difficulty.

[0081] As an optional embodiment, the step 302 comprises:

[0082] According to the connection-related information, a precoding matrix for transmitting the information bits and / or a modulation mode of the information bits is determined; and the information bits are processed based on the precoding matrix and / or the modulation mode.

[0083] In this embodiment, when processing the information bits, a precoding matrix can be determined according to the connection-related information, and the information bits are precoded according to the precoding matrix; and / or a modulation mode of the information bits is determined according to the connection-related information, and the information bits are modulated. The implementation process of the BSC UE for determining the precoding matrix and the implementation process of the BSC UE for determining the modulation mode are described below respectively.

[0084] Optionally, the determining of the precoding matrix for transmitting the information bits according to the connection-related information can include:

[0085] According to the precoding matrix information, the precoding matrix is determined; that is, the BSC UE can directly determine the precoding matrix according to the indication of the precoding matrix information.

[0086] Or

[0087] According to the signal modulation information and the uplink channel state information, the precoding matrix is determined.

[0088] Specifically, the determining of the precoding matrix according to the signal modulation information and the uplink channel state information can include the following two ways:

[0089] Way one: according to the signal modulation information, grouping information of the load impedance is determined; according to the uplink channel state information, a connection mode of the antenna and the grouped load impedance is determined; and the precoding matrix is generated according to the connection mode.

[0090] In this way one, the BSC UE determines the grouping of the load impedance according to the signal modulation information, and then determines the optimal load impedance connection mode from the grouped load impedance based on the uplink channel state information, so as to generate the precoding matrix.

[0091] Taking the modulation mode indicated by the signal modulation information as an example, the modulation mode is quaternary amplitude shift keying (4ASK), the BSC UE controls the antenna to select the corresponding load impedance to realize 4ASK in the grouping case according to the 4ASK modulation mode indicated by the signal modulation information, for example, Figure 4As shown, the load impedance is divided into two groups, Γ1 and Γ6 are two selected impedances for 4ASK. Based on the load impedance grouping and connection information when 4ASK modulation, combined with the uplink channel state information, Γ1 and Γ5 are selected at t1, and Γ2 and Γ6 are selected at t2, to generate the precoding matrix.

[0092] Method two: determining the grouping information of the load impedance according to the uplink channel state information; determining the connection mode of the antenna and the grouped load impedance according to the signal modulation information; and generating the precoding matrix according to the connection mode.

[0093] In this method two, the BSC UE determines the grouping of the load impedance based on the uplink channel state information, and then determines the optimal load impedance connection mode from the grouped load impedance according to the signal modulation information, thereby generating the precoding matrix.

[0094] As an optional embodiment, the method further comprises: obtaining the uplink channel state information; wherein the uplink channel state information is obtained by uplink channel measurement according to the pilot sequence.

[0095] In this embodiment, the uplink channel state information can be obtained by the first BSC receiving device performing uplink channel measurement according to the pilot sequence. The BSC UE can send the pilot sequence to the first BSC receiving device, and the first BSC receiving device can perform channel measurement according to the pilot sequence, obtain the uplink channel state information and send it to the BSC UE. Alternatively, the BSC UE can also obtain the uplink channel state information without sending the pilot sequence.

[0096] The following will illustrate the way of determining the precoding matrix through specific embodiments.

[0097] The first BSC receiving device can perform uplink channel measurement according to the pilot sequence sent by the BSC UE to determine the precoding matrix information. Alternatively, the BSC UE can perform downlink channel measurement to obtain downlink channel measurement information, and the first BSC receiving device can determine the precoding matrix information according to the pilot sequence and the downlink channel measurement information, thereby indicating the grouping of the load impedance and the connection of the load impedance and the antenna by using the precoding matrix information and / or signal modulation information.

[0098] If the precoding matrix indicated by the precoding matrix information is connected from the non-grouped / grouped load impedance, wherein the grouped load impedance is as shown in Figure 4 As shown, the non-grouped load impedance is as shown in Figure 5The generation principle of precoding matrix is introduced as follows in the case of grouping load impedances: in order to generate two beams (beam 1 and beam 2, T = 2) in different directions, 6 load impedances (Γ1-Γ6) are divided into two groups, each group having 3 load impedances, so as to generate a codebook with a dimension of 3 x 2. As shown in FIG. 3, Figure 4 , Γ1-Γ3 belong to the first group and Γ4-Γ6 belong to the second group, and two antennas can only be connected to two load impedances in the corresponding group at the same time. In this embodiment, beams in different directions are sequentially transmitted in the BSC uplink transmission process. When Γ1 and Γ5 are selected at t1, the phase information corresponding to Γ1 and Γ5 is selected. After Γ1 and Γ5 are selected, the phase of the exciting current changes, and based on the array factor expression (array response vector) of a linear array, the first beam can be obtained, as shown in beam 1 in FIG. 4. Figure 4 Similarly, Figure 4 the schematic diagram of beam 2 generated after Γ2 and Γ6 are selected is shown in FIG. 5.

[0099] Optionally, the determining of the modulation mode of the information bits according to the connection-related information can include:

[0100] (1) determining the modulation mode according to the signal modulation information; that is, the BSC UE can directly determine the modulation mode according to the signal modulation information.

[0101] Or

[0102] (2) determining the grouping information of the load impedances according to the precoding matrix indicated by the precoding matrix information; and determining the modulation mode according to the grouping information.

[0103] For the above-mentioned mode (2), the BSC UE indicates the precoding matrix according to the precoding matrix information, as shown in FIG. 6, groups the load impedances, selects Γ1 and Γ5 at t1, selects Γ2 and Γ6 at t2, and determines the modulation mode based on the existing grouping of load impedances and connection information. Figure 4

[0104] As an optional embodiment, the method further includes: transmitting a pilot sequence to the first BSC receiving device; and wherein the connection-related information is obtained by performing uplink channel measurement according to the pilot sequence.

[0105] ​In this embodiment, the connection-related information can be obtained by the first BSC receiving device according to channel measurement of the pilot sequence. The BSC UE sends a pilot sequence to the first BSC receiving device, the first BSC receiving device determines the precoding matrix information and / or the signal modulation information according to the pilot sequence, and sends the precoding matrix information and / or the signal modulation information to the BSC UE; optionally, the first BSC receiving device can also perform uplink channel measurement according to the pilot sequence to obtain the uplink channel state information.

[0106] Optionally, before the pilot sequence is sent to the first BSC receiving device, the method can further include: determining a first connection mode of the antenna and the load impedance; and modulating a pilot signal according to the first connection mode to obtain the pilot sequence.

[0107] The determination of the first connection mode of the antenna and the load impedance can include: randomly determining the load impedance connected to the antenna; or traversing each load impedance to determine the load impedance connected to the antenna.

[0108] In this embodiment, the first connection mode is used to realize the modulation of the pilot signal by the BSC UE. The BSC UE modulates the pilot signal according to the connection mode of the antenna and the load impedance, wherein the modulation of the pilot signal can include at least one of amplitude modulation, frequency modulation, and phase modulation. The determination method of the connection mode of the antenna and the load impedance can be: randomly determining that each antenna is connected to a certain load impedance; or traversing each load impedance, for example: at a first time, a first antenna is connected to a load impedance 1, at a second time, the first antenna is connected to a load impedance 2, and so on. The modulation process of the pilot sequence sent by the BSC UE is described below through specific embodiments.

[0109] Taking the pilot sequence used to obtain the uplink channel state information as an example, the modulation mode of the pilot sequence of the BSC UE is realized by the connection of the antenna and the load impedance, and the selection diagram of the load impedance is as shown in Figure 6 . It is assumed that the BSC UE has 2 antennas and 6 load impedances (Γ1-Γ6), and the state (open / closed) of the switch connected to each antenna can be controlled by a controller.

[0110] The antenna of the BSC UE realizes the sending of the pilot sequence (the pilot sequence can be a sequence composed of "0", "1" information bits) to the first BSC receiving device by selecting different impedance connection modes, which is used to obtain the uplink channel state information. The specific connection mode of the first connection mode can include:

[0111] 1) Randomly determine the connection of each antenna to a certain impedance, send "0" to represent the full absorption state of no connection, and send "1" to represent the selection of one from the six load impedances (Γ1~Γ6). This connection mode has great randomness, and the first BSC receiving device may receive a very weak pilot signal, but this mode can save power consumption and reduce latency.

[0112] 2) Determine the load impedance connected by the antenna by traversal: if considering the connection of one antenna to one load impedance, send "0" to represent the full absorption state of no connection, and send "1" to traverse the six load impedances (Γ1~Γ6) and select the load impedance with the maximum received power. If considering the connection of two antennas to two different load impedances, Γ1 and Γ2 can be selected to connect to the two antennas at the first time, Γ3 and Γ4 can be selected to connect to the two antennas at the second time, and so on. The first BSC receiving device can measure and obtain the pilot sequence with the strongest power through this connection mode, which is beneficial to subsequent communication. The following illustrates three different modulation modes for pilot sequence modulation:

[0113] 1) If considering the transmission of pilot sequence by binary amplitude shift keying (OOK) or binary phase shift keying (BPSK), only one antenna and two load impedances are needed to complete the transmission. When considering OOK, the phases of the two load impedances are set to be equal to the phase of the antenna impedance, "0" is sent to represent the full absorption state of no connection, and "1" is sent to represent the connection state. When considering BPSK, the phases of the two load impedances are set to be 90° apart, "0" is sent to represent the no connection state and the phase is 360°, and "1" is sent to represent the connection state and the phase is 0°.

[0114] 2) If considering the transmission of pilot sequence by quaternary amplitude shift keying (4ASK), two antennas and four load impedances are needed to complete the transmission, and the phases of two load impedances are set to be equal to the phase of the antenna impedance. The connection state of the two antennas and the load impedance is connected / not connected, which can realize the BSC UE to send "00" (both antennas are not connected to the load impedance), "10" or "01" (one antenna is connected to the load impedance), and "11" (both antennas are connected to the load impedance).

[0115] 3) If considering Quadrature Phase Shift Keying (QPSK) transmission pilot sequence, 4 load impedances need to be set as two groups, the phase of 2 load impedances in each group is 90°, two antennas are used for transmission simultaneously, and the connection state of the load impedance is connected / disconnected. Wherein, a) when the BSC UE sends "00", both antennas are not connected with the load impedance, and the phase is 360°; b) when the BSC UE sends "11", both antennas are connected with the load impedance, and the phase is 0°; c) when the BSC UE sends "10" or "01", only one antenna is connected with the load impedance. It should be noted that the reflection coefficient phase of different antennas will get different values.

[0116] The implementation process of the BSC UE determining the modulation mode is described below.

[0117] The first BSC receiving device can perform uplink channel measurement according to the pilot sequence sent by the BSC UE to determine signal modulation information; optionally, the BSC UE can perform downlink channel measurement to obtain downlink channel measurement information; and the first BSC device can jointly determine the signal modulation information based on the pilot sequence and the downlink channel measurement information.

[0118] If the signal modulation information indicates that the modulation mode of the BSC UE is amplitude modulation 4ASK, 2 antennas and 4 load impedances are needed to complete transmission, and the phase of 2 load impedances is set to be equal to the antenna impedance phase, and the state of the two antennas and the load impedance is connected / disconnected, which can realize the BSC UE to send "11" (indicating that both antennas are connected), "10" or "01" (indicating that one of the antennas is connected), and "00" (indicating that both antennas are not connected), and the phase of the remaining 4 load impedances can be set to a certain phase value in (0, 360°). Other modulation modes are similar to the modulation mode of the pilot sequence, which will not be described here.

[0119] Optionally, the method further comprises: obtaining a carrier signal; and the sending of the to-be-sent data can comprise modulating the to-be-sent data onto a carrier according to the carrier signal for transmission.

[0120] In this embodiment, the device for providing the carrier signal for the BSC UE to modulate the signal and the device for receiving the uplink data sent by the BSC UE can be the same device or different devices. Taking the BSC UE sending the uplink data to the first BSC receiving device as an example, the BSC UE modulates the uplink data according to the precoding matrix indicated by the precoding matrix information, such as Figure 4As shown, the load impedances are grouped, Γ1 and Γ5 are selected at t1, and Γ2 and Γ6 are selected at t2. Based on the existing load impedance grouping and connection information, the modulation mode is determined; the BSC UE can determine the precoding matrix according to the precoding matrix information, and the specific determination manner is not described herein.

[0121] After the BSC UE determines the modulation mode and / or the precoding matrix, the data stored in the memory is modulated to the carrier, and it is assumed that the modulated signal is s. When modulating and generating the precoding matrix, |s 11 | is less than -10 dB, the effective radiation of the modulated signal can be realized, and therefore, when obtaining the precoding matrix information and the modulation information, the BSC UE can enlarge the range of the reflection coefficient to (-1 / 3, 1 / 3) considering the transmission loss of the feeder and the like. The BSC UE changes the phase information of the backscattering signal by controlling the switching of different load impedances to obtain the precoding matrix F of the BSC UE, which can be directly multiplied with the modulated signal and then transmitted to the wireless channel through the antenna. The signal backscattered to the first BSC receiving device can be represented as Fs. After the BSC UE transmits the data to the first BSC receiving device, the first BSC receiving device receives and detects the uplink transmission data.

[0122] Optionally, the BSC UE transmitting the to-be-transmitted data can include: transmitting the to-be-transmitted data through a closed-loop uplink transmission mode; or transmitting the to-be-transmitted data through an open-loop uplink transmission mode.

[0123] Preferably, the precoding matrix information and / or the modulation information of the closed-loop uplink transmission mode depend on the accuracy of the uplink channel state information obtained by the first BSC receiving device; the open-loop uplink transmission mode has a lower degree of dependence on the uplink channel state information or the downlink channel state information. It should be noted that the embodiment of the present application takes the BSC UE transmitting the uplink data through the closed-loop uplink transmission mode as an example for description. Since in the closed-loop uplink transmission, the precoding matrix information and the modulation information depend on the accuracy of the uplink channel state information, the precoding matrix information and / or the modulation information can accurately indicate the grouping mode and the connection mode of the load impedance.

[0124] Optionally, the BSC UE transmitting the to-be-transmitted data can include: performing time division beam scanning and time division random beam forming on the to-be-transmitted data; and transmitting the to-be-transmitted data based on the formed beam.

[0125] In the embodiment, the uplink transmission of the BSC UE can be divided into time division beam scanning and time division random beam forming. In the formed beam, the connection between the load impedance and the antenna can be further switched to change the beam width. Alternatively, the controller of the BSC UE can control the simultaneous opening or closing of different switches to realize the weighting of the beam vector and further realize the target beam pointing.

[0126] In the embodiment of the present application, the arrangement mode of the load impedance can include a linear arrangement mode or a grouping arrangement mode. In the linear arrangement mode, the connection degree of freedom of the antenna and the load impedance is larger; in the grouping arrangement mode, the connection degree of freedom of the antenna and the load impedance is smaller. The modulation mode and the modulation order of the information bits of the BSC UE can be determined by the grouping of the load impedance and the connection of the antenna and the load impedance. The modulation mode can include amplitude modulation, phase modulation, frequency modulation and other modulation modes.

[0127] As an optional embodiment, the method further includes: sending configuration information to a network side device. The network side device is, for example, a base station. It should be noted that when the first BSC receiving device is a network side device (for example, a base station), the BSC UE sends the configuration information to the first BSC receiving device.

[0128] The configuration information includes at least one of the following:

[0129] Network configuration related information; the network configuration related information is the known network configuration reported by the BSC UE to the network side device, for example, a codebook indication (Transmitted Precoding Matrix Indicator, TPMI), a modulation mode in a modulation and coding scheme (Modulation and coding scheme, MCS) level, for example, a channel coding mode, a code rate, etc.

[0130] The number of antennas of the BSC terminal;

[0131] The number of load impedances of the BSC terminal;

[0132] The impedance value of the load impedance of the BSC terminal;

[0133] The energy storage information of the BSC terminal;

[0134] The working frequency of the BSC terminal;

[0135] The working bandwidth of the BSC terminal;

[0136] Switching speed of the BSC terminal.

[0137] Embodiments of the present application, the implementation process of the uplink transmission method is as shown in Figure 7 The first BSC receiving device is taken as an example, and the method comprises the following steps:

[0138] Step 71, the BSC UE sends a pilot sequence for uplink transmission to the BSC Receiver; optionally, the BSC UE can perform downlink channel measurement.

[0139] Step 72, the BSC Receiver determines the connection related information of the antenna and the load impedance according to the pilot sequence, such as the precoding matrix information and / or the signal modulation information, and indicates the grouping condition and the connection mode of the load impedance.

[0140] Step 73, the BSC UE performs uplink data transmission according to the grouping condition and the connection mode of the load impedance.

[0141] Embodiments of the present application, on the basis of the existing BSC technology, compared with the traditional single-antenna BSC link transmission, based on the hardware architecture, modulation mode and precoding design of BSC, considering the modulation information and the precoding matrix information, determining the grouping condition of the load impedance, jointly controlling the phase change of different reflection coefficients, further determining the BSC multi-antenna uplink transmission scheme, which can avoid the problems of signal distortion, large bit error rate in transmission process and detection difficulty.

[0142] As shown in Figure 8 The embodiments of the present application also provide an uplink transmission method, applied to a BSC receiving device, the BSC receiving device is the first BSC receiving device, and the method comprises the following steps:

[0143] Step 801, the BSC receiving device determines the connection related information of the antenna and the load impedance of the BSC terminal according to the pilot sequence; wherein the connection related information comprises: precoding matrix information and / or signal modulation information.

[0144] The BSC receiving device is the first BSC receiving device, for example, a BSC receiver, a base station, or a terminal having the same hardware structure as the first BSC receiving device, etc. The first BSC receiving device determines the precoding matrix information and / or signal modulation information according to the pilot sequence of the BSC UE, which can indicate the connection mode of the antenna and load impedance of the BSC UE. After the BSC receiving device determines the precoding matrix information and / or signal modulation information, the precoding matrix and / or modulation mode of the information bits transmitted by the BSC UE are also determined.

[0145] In step 802, the BSC receiving device sends the connection-related information to the BSC terminal.

[0146] The BSC receiving device sends the precoding matrix information and / or signal modulation information to the BSC UE, and the connection criteria of the BSC UE antenna and load impedance can be indicated by the precoding matrix information and / or signal modulation information determined by the BSC receiving device. The BSC UE encodes and / or modulates information bits according to the precoding matrix information and / or signal modulation information, thereby obtaining uplink data.

[0147] Optionally, the method further comprises: sending transmission-related information to the BSC terminal; and the transmission-related information comprises: a channel coding mode and / or a code rate. That is, the BSC receiving device can also send channel coding mode, code rate, and other related information to the BSC UE.

[0148] Optionally, the method further comprises: receiving data sent by the BSC terminal according to the connection-related information.

[0149] In this embodiment, the BSC receiving device is the first BSC receiving device. After the BSC UE encodes and / or modulates information bits according to the precoding matrix information and / or signal modulation information, and obtains uplink data to be transmitted, the BSC UE can send the uplink data to the first BSC receiving device, or can send the uplink data to a second BSC receiving device, which is different from the BSC receiving device in the embodiment of the present application.

[0150] As an optional embodiment, the determining of the connection-related information of the antenna and load impedance of the BSC terminal comprises: performing uplink channel measurement according to the pilot sequence to obtain the connection-related information; and the connection-related information is obtained when the signal energy and / or signal quality of the BSC receiving device performing uplink channel measurement is greater than or equal to a first threshold value.

[0151] In this embodiment, the BSC receiving device performs uplink channel measurement according to the pilot sequence sent by the BSC UE to obtain the precoding matrix information and / or the signal modulation information. The precoding matrix information and / or the signal modulation information are determined according to the best signal energy and / or signal quality of the BSC receiving device, i.e., the precoding matrix information and / or the signal modulation information corresponding to the best signal quality and / or the best signal energy (greater than or equal to a first threshold) are obtained when the BSC receiving device performs uplink channel measurement. The first threshold can be set according to the signal quality or signal energy requirement.

[0152] The implementation process of the BSC receiving device determining the precoding matrix information and the signal modulation information will be described below respectively through specific embodiments.

[0153] The BSC UE can perform downlink channel measurement to obtain downlink channel measurement information, and the BSC receiving device can jointly determine the precoding matrix information according to the pilot sequence and the downlink channel measurement information, so as to indicate the grouping situation of the load impedance and the connection situation of the load impedance and the antenna by using the precoding matrix information and / or the signal modulation information.

[0154] If the precoding matrix information indicates that the precoding matrix is obtained from the connection of the load impedance without grouping / grouping, the load impedance grouping situation is as shown in Figure 4 , and the load impedance non-grouping situation is as shown in Figure 5 . The generation principle of the precoding matrix will be introduced below in the load impedance grouping situation: in order to generate two different direction beams (beam 1 and beam 2, T=2), 6 load impedances (Γ1-Γ6) are divided into 2 groups, each group has 3 load impedances, and a codebook with a dimension of 3x2 can be generated. As shown in Figure 4 , Γ1-Γ3 are in the first group, Γ4-Γ6 are in the second group, and two antennas can only select two load impedances in the corresponding grouping impedance to be connected at the same time. In this embodiment, different direction beams are sent in sequence during the BSC uplink transmission process. When Γ1 and Γ5 are selected at t1, the phase information corresponding to Γ1 and Γ5 is selected. After selecting Γ1 and Γ5, the phase of the excitation current changes, and based on the array factor expression (array response vector) of the linear array, the first beam can be obtained, as shown in beam 1 in Figure 4 . Similarly, Figure 4 , the diagram of assuming that Γ2 and Γ6 are selected to generate beam 2 is given.

[0155] The BSC receiving device performs uplink channel measurement according to the pilot sequence sent by the BSC UE, and determines the signal modulation information (optionally, the signal modulation information can also be determined jointly with the downlink channel measurement information). If the modulation mode of the BSC UE indicated in the signal modulation information is amplitude modulation 4ASK, 2 antennas and 4 load impedances are required to complete transmission, and the phases of 2 load impedances are set to be equal to the phase of the antenna impedance, and the states of the two antennas and the load impedance are connection / disconnection states, so that the BSC UE can send "11" (indicating that both antennas are connected), "10" or "01" (indicating that one of the antennas is connected), and "00" (indicating that both antennas are not connected), and the phases of the remaining 4 load impedances can be set to a certain phase value in (0, 360°).

[0156] Optionally, the method further comprises: performing uplink channel measurement according to the pilot sequence to obtain uplink channel state information; and sending the uplink channel state information to the BSC terminal.

[0157] In this embodiment, the BSC receiving device can also perform uplink channel measurement according to the pilot sequence sent by the BSC UE, so as to obtain uplink channel state information, and send the uplink channel state information to the BSC UE; and the BSC UE can determine the precoding matrix according to the uplink channel state information and the signal modulation information. Optionally, the BSC UE can also obtain the uplink channel state information in the manner of sending no pilot sequence.

[0158] Optionally, the method further comprises: receiving the pilot sequence sent by the BSC terminal.

[0159] In this embodiment, the BSC UE sends a pilot sequence to the BSC receiving device, the BSC receiving device determines the precoding matrix information and / or the signal modulation information according to the pilot sequence, and sends the precoding matrix information and / or the signal modulation information to the BSC UE.

[0160] The BSC UE can modulate the pilot signal based on the connection mode of the antenna and the load impedance (i.e., the first connection mode), and the modulation of the pilot signal can include at least one of amplitude modulation, frequency modulation, and phase modulation. The BSC UE can randomly determine the load impedance connected to the antenna, or traverse each load impedance to determine the load impedance connected to the antenna. The specific process of the BSC UE performing pilot signal modulation is not described here.

[0161] Optionally, the arrangement mode of the load impedance includes a linear arrangement mode with a larger connection degree of freedom of the antenna and the load impedance and a grouping arrangement mode with a smaller connection degree of freedom.

[0162] In the embodiments of the present application, the BSC receiving device can be a network side device, such as a base station, which interacts with the BSC UE. When the BSC receiving device is a network side device, the BSC UE sends configuration information to the BSC receiving device. Optionally, the method further comprises:
