[0045] The communication methods, devices, terminals, network-side equipment, and media provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0046] Figure 2 A flowchart illustrating a communication method provided in an embodiment of this application is shown. Figure 2 As shown, the communication method provided in this application embodiment may include the following steps 101 to 104.

[0047] Step 101: The first device sends a first signal to the UE.

[0048] In this embodiment of the application, the first signal is used by the UE to obtain the target bit; the target bit is carried on the first signal and the BSC signal respectively, and the BSC signal is obtained by the BSC device modulating the first signal.

[0049] Optionally, in the embodiments of this application, the first device mentioned above includes any one of the following: a base station, a BSC device, other UEs, etc.

[0050] Further optionally, in the embodiments of this application, when the first device is a base station, the base station can be any of the following: another UE, a relay device, a device-to-device (D2D) device, a sidelink device, etc.

[0051] Further optionally, in the embodiments of this application, when the first device is a BSC device, the BSC device can also be a RIS device; wherein, the power supply and radio frequency source (i.e. the first signal) of the BSC device can be the same device or different devices.

[0052] The power supply method of the BSC equipment may include at least one of the following: the BSC equipment is powered by base station radio frequency signals, the BSC equipment is powered by other radio frequency signals, or the BSC equipment is powered by non-radio frequency signals. The non-radio frequency signal function may include at least one of the following: mechanical power supply, vibration power supply, solar power supply, thermal power supply, etc.

[0053] In this embodiment of the application, when other communication devices (such as the second device in the following embodiments) need to transmit target bits to the UE, the first device may send a first signal to the UE. The communication device may include at least one of the following: a base station, a BSC device, another UE, etc.

[0054] Step 102: The BSC device sends a BSC signal to the UE.

[0055] It can be understood that the BSC signal mentioned above is the BSC signal associated with the first signal.

[0056] In this embodiment of the application, the BSC signal is used by the UE to obtain the target bit; the target bit is carried on the first signal and the BSC signal respectively, the first signal is the signal sent by the first device to the UE; the BSC signal is obtained by the BSC device modulating the first signal.

[0057] Optionally, in this embodiment, the first device can modulate a portion of the target bit onto the first signal and send the first signal to the UE. Furthermore, the BSC device can modulate another portion of the target bit onto the first signal using backscattering to generate a BSC signal. The BSC device can then send the BSC signal to the UE, allowing the UE to acquire both the first and second portions of the bit to obtain the target bit.

[0058] Alternatively, in this embodiment of the application, the BSC device may use an FM0 code-based method to modulate another portion of the target bit onto the first signal to generate a BSC signal.

[0059] For example, Figure 3 This diagram illustrates how a BSC device modulates another portion of the target bit onto the first signal. (See diagram for example.) Figure 3 As shown, the BSC device can modulate the other part of the bits onto the first signal using Amplitude Shift Keying (ASK) based on FMO code to generate a BSC signal.

[0060] The following two different examples illustrate how the first device and the BSC device send signals.

[0061] Example 1:

[0062] The first device can modulate a portion of the bits (e.g., the first group of bits in the following embodiment) generated by channel coding of the target bit onto the first signal and send the first signal to the UE; and the BSC device can modulate another portion of the bits (e.g., the second group of bits in the following embodiment) generated by channel coding of the target bit onto the first signal to generate a BSC signal and send the BSC signal to the UE.

[0063] Both of these bits consist of: channel-coded bits (information).

[0064] In this example, the first device can first acquire the portion of bits and then modulate the portion of bits onto the first signal; and the BSC device can first acquire the other portion of bits and then modulate the other portion of bits onto the first signal to generate the BSC signal.

[0065] For example, the first device can directly obtain the portion of bits from the first device; or, the first device can receive the portion of bits from other communication devices (such as the second device in the following embodiments). The BSC device can obtain the other portion of bits from the first device; or, the BSC device can receive the other portion of bits from other communication devices.

[0066] Specifically, the target bits mentioned above include a first group of bits and a second group of bits. (Combined) Figure 2 ,like Figure 4 As shown, prior to step 101 above, the communication method provided in this application embodiment may further include steps 201 to 204 as described below.

[0067] Step 201: The first device acquires the first set of bits.

[0068] In this embodiment of the application, the first set of bits is obtained by splitting the first bit by the second device; the second device includes any one of the following: the first device, other devices; the first bit is a bit generated by channel coding of the target bit.

[0069] It is understood that the aforementioned other equipment may specifically include at least one of the following: base station, BSC equipment, other UEs, etc.

[0070] Step 202: The BSC device acquires the second set of bits.

[0071] In this embodiment of the application, the second set of bits is obtained by splitting the first bit by the second device; the second device includes any one of the following: the first device, other devices; the first bit is a bit generated by channel coding of the target bit.

[0072] Further optionally, in this embodiment of the application, the second device may first perform channel coding on the target bit to obtain the first bit, and then split the first bit into a first group of bits and a second group of bits, so that the first device can obtain the first group of bits and the BSC device can obtain the second group of bits.

[0073] It can be understood that the first and second sets of bits are obtained by splitting the encoded information from the same source.

[0074] In the case where the second device is the first device, the target bit can be information pre-stored in the first device (or information received from other devices), so the first device can directly perform channel coding on the target bit to obtain the first bit, and then the first device can obtain the first set of bits and send the second set of bits to the BSC device.

[0075] When the second device is another device, the target bit can be information pre-stored in that other device (or information received from another communication device). Thus, the other device can perform channel coding on the target bit to obtain the first bit. Then, the other device can send the first set of bits to the first device and send the second set of bits to the BSC device, so that the first device can obtain the first set of bits and the BSC device can obtain the second set of bits.

[0076] Specifically, the first group of bits and the second group of bits can be the same or different.

[0077] For example, assuming the target bit is 100 bits of information, the second device (e.g., other devices) can perform channel coding on the target bit at a code rate of 0.5 to obtain the first bit (i.e., 200 bits of information). Then, the other device can split the 200 bits of information into 180 bits of information (i.e., the first group of bits) and 20 bits of information (i.e., the second group of bits), that is, the first group of bits and the second group of bits are different, so that the first device can obtain the 180 bits of information and the BSC device can obtain the 20 bits of information.

[0078] For example, let's take the first device as a base station for illustration. Figure 5 As shown, other devices can perform channel coding of the target bits at a code rate of 0.5 to obtain the first bit (e.g., "11000...00011..." information), so that the base station 10 can obtain the first group of bits (i.e., "11000" information), and the BSC device 11 can obtain the second group of bits (i.e., "00011" information). Then, the base station 10 can send the first signal to the UE 12, and the BSC device 11 can send the BSC signal to the UE 12.

[0079] For example, suppose that the target bits generate multiple RV redundancy versions after channel coding. A second device (e.g., a first device) can then split these multiple RV redundancy versions into X RV redundancy versions (i.e., the first group of bits) and Y RV redundancy versions (i.e., the second group of bits), where the first group of bits and the second group of bits are different. This allows the first device to obtain the X RV redundancy versions, and the BSC device to obtain the Y RV redundancy versions. Here, X and Y are both positive integers.

[0080] For example, assuming the target bit is 100 bits of information, the second device (e.g., the first device) can perform channel coding on the target bit at a code rate of 0.5 to obtain the first bit (i.e., 200 bits of information). The first device can then make a copy of the 200 bits of information, that is, one 200-bit information (i.e., the first group of bits) and another 200-bit information (i.e., the second group of bits). In other words, the first group of bits and the second group of bits are the same, so that the first device can obtain the one 200-bit information, and the BSC device can obtain the other 200-bit information.

[0081] Step 203: The first device modulates the first set of bits onto the first signal.

[0082] Step 204: The BSC device modulates the second set of bits onto the first signal to generate the BSC signal.

[0083] Thus, since the first device can acquire a portion of the bits generated after the target bit is channel-coded and modulate that portion of the bits onto the first signal, and the BSC device can acquire another portion of the bits generated after the target bit is channel-coded and modulate that other portion of the bits onto the BSC signal, the target bit is carried by both the first signal and the BSC signal, rather than by the first signal carrying all the bits of the target bit. Therefore, the time for transmitting that portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bit.

[0084] Example 2:

[0085] The first device can perform channel coding on a portion of the target bits (e.g., the third group of bits in the following embodiment), and then modulate the channel-coded bits onto the first signal; and the BSC device can perform channel coding on another portion of the target bits (e.g., the fourth group of bits in the following embodiment), and then modulate the channel-coded bits onto the first signal to generate a BSC signal.

[0086] Both of these bits consist of uncoded bits (information).

[0087] In this example, the first device can first acquire a portion of the bits and then modulate that portion of the bits onto the first signal; the BSC device can first acquire the other portion of the bits and then modulate that other portion of the bits onto the first signal to generate the BSC signal.

[0088] Specifically, the target bits mentioned above include the third group of bits and the fourth group of bits. (Combined) Figure 2 ,like Figure 6As shown, prior to step 101 above, the communication method provided in this application embodiment may further include steps 301 to 304 as described below.

[0089] Step 301: The first device acquires the third set of bits.

[0090] In this embodiment of the application, the third set of bits is obtained by splitting the target bits by the second device; the second device includes any one of the following: the first device, or other devices.

[0091] It is understood that the aforementioned other equipment may specifically include at least one of the following: base station, BSC equipment, other UEs, etc.

[0092] Step 302: The BSC device obtains the fourth set of bits.

[0093] In this embodiment of the application, the fourth group of bits is obtained by splitting the target bits by the second device; the second device includes any one of the following: the first device, or other devices.

[0094] Further optionally, in this embodiment of the application, the second device can directly split the target bits into a third group of bits and a fourth group of bits, so that the first device can obtain the third group of bits and the BSC device can obtain the fourth group of bits.

[0095] It can be understood that the third and fourth sets of bits are obtained by splitting the same source information.

[0096] In the case where the second device is the first device, the target bits can be information pre-stored in the first device (or information received from other devices), so that the first device can directly obtain the third set of bits and send the fourth set of bits to the BSC device.

[0097] When the second device is another device, the target bits can be information pre-stored in that other device (or information received from another communication device), so that the other device can send a third set of bits to the first device and a fourth set of bits to the BSC device, so that the first device can obtain the third set of bits and the BSC device can obtain the fourth set of bits.

[0098] Specifically, the third and fourth sets of bits can be the same or different.

[0099] Step 303: The first device performs channel coding on the third group of bits and modulates the generated bits after channel coding onto the first signal.

[0100] Step 304: The BSC device performs channel coding on the fourth group of bits and modulates the generated bits after channel coding onto the first signal to generate the BSC signal.

[0101] Thus, since the first device can acquire a portion of the target bits and modulate the resulting bits after channel coding onto the first signal, and the BSC device can acquire another portion of the target bits and modulate the resulting bits after channel coding onto the BSC signal, the target bits are carried by both the first signal and the BSC signal, rather than by carrying all the target bits on the first signal alone. Therefore, the time for transmitting the portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bits.

[0102] Step 103: The UE receives a first signal from the first device and a BSC signal from the BSC device.

[0103] In this embodiment of the application, the BSC signal is obtained by the BSC device modulating the first signal.

[0104] Step 104: The UE obtains the target bit based on the first signal and the BSC signal.

[0105] In this embodiment of the application, the target bits are respectively carried on the first signal and the BSC signal.

[0106] Optionally, in this embodiment of the application, the UE can demodulate the first signal and the BSC signal respectively, or the UE can demodulate and decode the first signal and the BSC signal respectively to obtain all bits of the target bit, so that the UE can obtain the target bit.

[0107] The following two different examples illustrate how the UE obtains the target bits.

[0108] Example 3: The target bits include the first group of bits and the second group of bits:

[0109] Specifically, step 104 can be implemented through steps 104a and 104b below.

[0110] Step 104a: The UE demodulates the first signal to obtain the first set of bits, and demodulates the BSC signal to obtain the second set of bits.

[0111] Step 104b: The UE performs joint channel decoding on the first group of bits and the second group of bits to obtain the target bits.

[0112] In this embodiment of the application, the first group of bits and the second group of bits are both: the second device splits the first bit and sends it to the first device and the BSC device respectively; the second device includes any one of the following: the first device, other devices; the first bit is: the bit generated after the target bit is channel coded.

[0113] Alternatively, in this embodiment of the application, the UE can merge the first group of bits and the second group of bits, and perform joint channel decoding (unified channel decoding) on ​​the merged bits to obtain the target bits.

[0114] Example 4: The target bits include the third and fourth groups of bits:

[0115] Specifically, step 104 can be implemented through steps 104c and 104d as described below.

[0116] Step 104c: The UE demodulates and decodes the first signal to obtain the third set of bits, and demodulates and decodes the BSC signal to obtain the fourth set of bits.

[0117] In this embodiment of the application, the third and fourth sets of bits are both: after the second device splits the target bits, they are sent to the first device and the BSC device respectively; the second device includes any one of the following: the first device, other devices.

[0118] Optionally, in this embodiment of the application, the third set of bits is: data information; the fourth set of bits is: target control information.

[0119] Alternatively, in this embodiment of the application, the third set of bits (i.e., data information) is associated with the target control information (i.e., the fourth set of bits).

[0120] Further, optionally, in this embodiment of the application, the aforementioned target control information includes at least one of the following:

[0121] Acknowledgment / denial (ACK / NACK) messages;

[0122] Downlink control information (DCI) corresponding to the data information.

[0123] For example, assuming the target control information is ACK / NACK information, if the first device or other device successfully receives the data information sent by the UE, the target control information is ACK information; if the first device or other device fails to receive the data information sent by the UE, the target control information is NACK information.

[0124] Further optionally, in this embodiment of the application, there is a first correspondence between the transmission time corresponding to the first signal and the transmission time corresponding to the BSC signal. Wherein, the first correspondence is either agreed upon by the protocol or configured by the first device.

[0125] Specifically, the aforementioned first correspondence can be either a correspondence between one time point and another, or a correspondence between one time unit and another. The time unit can be any of the following: time slot, subframe, symbol, micro-time slot, mini-time slot, etc.

[0126] For example, assuming the transmission time corresponding to the first signal is T1, that is, the first device transmits the first signal at time T1. According to the first correspondence, T1 corresponds to T2. Then the transmission time corresponding to the BSC signal is T2. That is, the BSC device modulates the information onto the first signal at time T2 to generate the BSC signal (that is, the first device also transmits the first signal at time T2).

[0127] For example, suppose the transmission time corresponding to the first signal is subframe M, that is, the first device transmits the first signal in subframe M. According to the first correspondence, M corresponds to N. Then the transmission time corresponding to the BSC signal is subframe N. That is, the BSC device modulates the information onto the first signal transmitted in subframe N, thereby generating the BSC signal (that is, the first device also transmits the first signal in subframe N).

[0128] Step 104d: The UE obtains the target bit based on the third and fourth sets of bits.

[0129] Alternatively, in this embodiment of the application, the UE can merge the third group of bits and the fourth group of bits to obtain the target bits.

[0130] The communication method provided in this application embodiment allows the UE to receive a first signal and a BSC signal (the BSC signal is obtained by the BSC device modulating the first signal) from a first device and a BSC device, respectively. The UE can then obtain the target bit carried on the first signal and the BSC signal, respectively. Since the target bit is carried on both the first signal and the BSC signal modulated from the first signal when transmitting information (i.e., the target bit) to the UE, meaning the first signal only carries a portion of the target bit, not all of it, the time spent transmitting this portion of the bit via the first signal can be reduced, thus reducing the time spent transmitting the target bit and improving information transmission efficiency.

[0131] Of course, before receiving the first signal and the BSC signal, the UE can also receive the transmission parameters of the first signal and the BSC signal. The following will illustrate this with two different examples.

[0132] Example 5: The UE receives the transmission parameters of the first signal and the BSC signal from the first device.

[0133] Specifically, prior to step 101 above, the communication method provided in this application embodiment may further include steps 401 and 402 as described below.

[0134] Step 401: The first device sends the first control information to the UE.

[0135] In this embodiment of the application, the first control information is used to indicate the transmission parameters of the first signal and the BSC signal.

[0136] Further optionally, in this embodiment of the application, the aforementioned first control information may specifically be: first sub-control information and second sub-control information. The first sub-control information is used to indicate the transmission parameters of the first signal; the second sub-control information is used to indicate the transmission parameters of the BSC signal.

[0137] Further optionally, in the embodiments of this application, the above transmission parameters may include at least one of the following: time domain parameters, frequency domain parameters, etc.

[0138] Step 402: The UE receives first control information from the first device.

[0139] Thus, since the UE can receive the transmission parameters of the first signal and the BSC signal from the first device, the UE can accurately receive the first signal and the BSC signal.

[0140] Example 6: The UE receives the transmission parameters of the first signal from the first device and the transmission parameters of the BSC signal from the BSC device.

[0141] Specifically, prior to step 101 above, the communication method provided in this application embodiment may further include steps 501 to 503 as described below.

[0142] Step 501: The first device sends the second control information to the UE.

[0143] In this embodiment of the application, the second control information is used to indicate the transmission parameters of the first signal.

[0144] Step 502: The BSC device sends third control information to the UE.

[0145] In this embodiment of the application, the aforementioned third control information is used to indicate the transmission parameters of the BSC signal.

[0146] It should be noted that the execution order of steps 501 and 502 is not limited in this embodiment of the application.

[0147] In one possible implementation, step 501 can be executed first, followed by step 502. That is, the first device can first send the second control information to the UE, and then the BSC device can send the third control information to the UE.

[0148] In another possible implementation, step 502 can be executed first, followed by step 501. That is, the BSC device can first send the third control information to the UE, and then the first device can send the second control information to the UE.

[0149] In another possible implementation, step 502 can be performed simultaneously with step 501, that is, while the first device sends the second control information to the UE, the BSC device can send the third control information to the UE.

[0150] Step 503: The UE receives second control information from the first device and third control information from the BSC device.

[0151] Thus, it can be seen that since the UE can receive the transmission parameters of the first signal and the BSC signal from the first device and the BSC device respectively, the UE can accurately receive the first signal and the BSC signal.

[0152] The following will provide examples illustrating the specific content included in the transmission parameters. These transmission parameters can be: the transmission parameters of the first signal, and / or the transmission parameters of the BSC signal.

[0178] In this embodiment of the application, the target time interval is used to indicate the time interval between the transmission time of the control information and the corresponding bit transmission time.

[0179] It should be noted that the "corresponding bits" mentioned above can be understood as the bits carried on the control information indication signal.

[0191] The timing information for periodic transmission can specifically refer to the possible time periods of periodic transmission. For example, which periods might transmit bits (information).

[0193] Further optionally, in this embodiment, the symbol length of the BSC signal can be the time length occupied by the BSC device transmitting 0 or 1. For example, transmitting 0 or 1 occupies one subframe or time slot.

[0194] Further optionally, in this embodiment, the transmission duration of the BSC signal can specifically be the length of the transmission cycle of the BSC signal. It is understood that the UE needs to buffer the BSC signal of this transmission duration before demodulation.

[0195] In this embodiment of the application, the above-mentioned delimiter is used to indicate the start time of the BSC signal; the above-mentioned preamble is used by the receiving device (i.e., UE) of the BSC signal for synchronization or channel estimation.

[0199] Specifically, the start time of the symbol or time slot of the aforementioned BSC signal can be either an absolute time or a relative time.

[0200] For example, assuming the start time is T1, if this start time is an absolute time, then the start time of the symbol or time slot of the BSC signal is T1.

[0201] When the starting time is a relative time, the starting time of the symbol or time slot of the BSC signal can be: the time before (or after) the target time T1; wherein, the target time can be the starting time of the symbol or time slot of the first signal.

That is, the first signal only carries a portion of the target bits, not all of the target bits.

That is, the first signal only carries a portion of the target bits, not all of the target bits.

[0242] The third communication device provided in this application embodiment can achieve... Figures 1 to 6 The various processes implemented in the method embodiments achieve the same technical effect, and will not be described again here to avoid repetition.

[0243] Optionally, in the embodiments of this application, such as Figure 10 As shown in the illustration, this application also provides a communication device 70, including a processor 71 and a memory 72.

Figure 11 The terminal structure shown does not constitute a limitation on the terminal. The terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements, which will not be elaborated here.

[0247] It should be understood that, in this embodiment, the input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos obtained by an image capture device (such as a camera) in video capture mode or image capture mode.

[0248] In this embodiment, after receiving downlink data from the network-side device, the radio frequency unit 101 can transmit it to the processor 110 for processing; in addition, the radio frequency unit 101 can send uplink data to the network-side device. Typically, the radio frequency unit 101 includes, but is not limited to, antennas, amplifiers, transceivers, couplers, low-noise amplifiers, duplexers, etc.

The memory 109 in the embodiments of this application includes, but is not limited to, these and any other suitable types of memory.

[0250] Processor 110 may include one or more processing units; optionally, processor 110 integrates an application processor and a modem processor, wherein the application processor mainly handles operations involving the operating system, user interface, and applications, and the modem processor mainly handles wireless communication signals, such as a baseband processor. It is understood that the aforementioned modem processor may also not be integrated into processor 110.

[0251] The radio frequency unit 101 is used to receive a first signal from the first device and a BSC signal from the BSC device; the BSC signal is obtained by the BSC device modulating the first signal.

[0252] The processor 110 is used to obtain a target bit based on the first signal and the BSC signal; the target bit is carried on the first signal and the BSC signal respectively.

[0253] The terminal provided in this application embodiment transmits information (i.e., target bits) to the terminal by carrying the target bits on a first signal and a BSC signal obtained by modulating the first signal. That is, the first signal carries only a portion of the target bits, not all of them. Therefore, the time for transmitting the portion of the target bits through the first signal can be reduced, thereby reducing the time for transmitting the target bits and improving the efficiency of information transmission.

[0254] Optionally, in this embodiment of the application, the processor 110 is specifically used to demodulate the first signal to obtain a first set of bits, and demodulate the BSC signal to obtain a second set of bits; and perform joint channel decoding on the first set of bits and the second set of bits to obtain the target bits.

[0255] Wherein, the first group of bits and the second group of bits mentioned above are: the second device splits the first bit and sends it to the first device and the BSC device respectively; the second device includes any one of the following: the first device, other devices; the first bit is: the bit generated after the target bit is channel-coded.

[0256] Thus, since the first device can acquire a portion of the bits generated after the target bit is channel-coded and modulate that portion of the bits onto the first signal, and the BSC device can acquire another portion of the bits generated after the target bit is channel-coded and modulate that other portion of the bits onto the BSC signal, the target bit is carried by both the first signal and the BSC signal, rather than by the first signal carrying all the bits of the target bit. Therefore, the time for transmitting that portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bit.

[0257] Optionally, in this embodiment of the application, the processor 110 is specifically used to demodulate and channel decode the first signal to obtain a third set of bits, and to demodulate and channel decode the BSC signal to obtain a fourth set of bits; and to obtain the target bits based on the third set of bits and the fourth set of bits.

[0258] The third and fourth sets of bits mentioned above are: after the second device splits the target bits, it sends them to the first device and the BSC device respectively; the second device includes any one of the following: the first device and other devices.

[0259] Thus, since the first device can acquire a portion of the target bits and modulate the resulting bits after channel coding onto the first signal, and the BSC device can acquire another portion of the target bits and modulate the resulting bits after channel coding onto the BSC signal, the target bits are carried by both the first signal and the BSC signal, rather than by carrying all the target bits on the first signal alone. Therefore, the time for transmitting the portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bits.

[0260] Optionally, in this embodiment of the application, the radio frequency unit 101 is further configured to receive first control information from the first device; or, receive second control information from the first device and receive third control information from the BSC device.

It is understood that the aforementioned modem processor may also not be integrated into processor 110.

[0269] The radio frequency unit 101 is used to send BSC signals to the UE.

[0270] The BSC signal is used by the UE to obtain the target bit; the target bit is carried on the first signal and the BSC signal respectively. The first signal is the signal sent by the first device to the UE; the BSC signal is obtained by the BSC device modulating the first signal.

[0271] The terminal provided in this application embodiment transmits information (i.e., target bits) to the terminal by carrying the target bits on a first signal and a BSC signal obtained by modulating the first signal. That is, the first signal carries only a portion of the target bits, not all of them. Therefore, the time for transmitting the portion of the target bits through the first signal can be reduced, thereby reducing the time for transmitting the target bits and improving the efficiency of information transmission.

[0272] Optionally, in this embodiment of the application, the target bits include a second set of bits.

[0273] The radio frequency unit 101 is also used to acquire the second set of bits.

[0275] The second set of bits mentioned above is obtained by splitting the first bit by the second device; the second device includes any one of the following: the first device, other devices; the first bit is the bit generated by channel coding of the target bit.

[0276] Thus, since the first device can acquire a portion of the bits generated after the target bit is channel-coded and modulate that portion of the bits onto the first signal, and the BSC device can acquire another portion of the bits generated after the target bit is channel-coded and modulate that other portion of the bits onto the BSC signal, the target bit is carried by both the first signal and the BSC signal, rather than by the first signal carrying all the bits of the target bit. Therefore, the time for transmitting that portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bit.

[0277] Optionally, in this embodiment of the application, the target bits include a fourth set of bits.

[0278] The radio frequency unit 101 is also used to acquire the fourth set of bits.

[0279] The processor 110 is also used to perform channel coding on the fourth group of bits and modulate the channel-coded bits onto the first signal to generate a BSC signal.

[0280] The fourth set of bits is obtained by splitting the target bits by the second device; the second device includes any of the following: the first device or other devices.

[0281] Thus, since the first device can acquire a portion of the target bits and modulate the resulting bits after channel coding onto the first signal, and the BSC device can acquire another portion of the target bits and modulate the resulting bits after channel coding onto the BSC signal, the target bits are carried by both the first signal and the BSC signal, rather than by carrying all the target bits on the first signal alone. Therefore, the time for transmitting the portion of the bits through the first signal can be reduced, thereby reducing the time for transmitting the target bits.

[0282] Optionally, in this embodiment of the application, the radio frequency unit 101 is also used to send third control information to the UE.
