Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0176] In some embodiments, a terminal using backscattering requires a continuous wave (CW) energy source, such as a CW node, to provide the reflected electromagnetic wave while transmitting information. CW waves typically have a constant amplitude. The frequency of the electromagnetic wave reflected by the terminal can be exactly the same as the CW frequency, or there can be an offset. The offset depends on the hardware characteristics of the terminal and can be fixed or dynamically adjustable.

[0177] In ambient IoT scenarios, one possible approach to frequency resource utilization is to divide the available spectrum into multiple subchannels. Each subchannel occupies a fixed bandwidth, and the subchannels are orthogonal in the frequency domain. The network can instruct a terminal to use one or more of these subchannels for transmission, or the terminal can select one or more subchannels based on an algorithm.

[0178] In some embodiments, terminals using backscattering have relatively wide antenna operating bandwidths, such as tens of MHz. If a CW node transmits a CW on multiple subchannels within the terminal's antenna reception bandwidth, the terminal will receive the CWs on these subchannels and perform backscatter on all of them. This means that the terminal lacks the ability to reflect only the CWs for a specific subchannel of its choice. Therefore, the uplink subchannel a terminal can use depends on the CW frequency and offset capabilities.

[0179] In some scenarios, if one or more terminals are transmitting on subchannels 1, 2, or 3, a CW with the corresponding frequency is required on these subchannels. However, given the terminal's offset capability, the subchannel location of the CW may vary. Furthermore, coordination between the CW frequency and the terminal's subchannel frequency is also a consideration.

[0180] 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 an information processing method, which includes:

[0181] Step S2101: The terminal sends first information to the network device.

[0182] In some embodiments, the first information is used to indicate the frequency shift capability of the terminal in reflecting continuous electromagnetic waves CW.

[0183] In some embodiments, the first information is used to indicate a frequency offset type supported by the terminal. Optionally, the first information is used to indicate that the terminal supports at least one of the following: double sideband offset; single sideband offset.

[0184] Optionally, when the terminal supports double-sideband offset, the terminal can shift the CW frequency upward and downward respectively. For example, taking the CW frequency as f0, the terminal can shift the CW frequency upward and downward respectively. H and f0+f H Uplink information is transmitted at two frequency points, and the uplink information transmitted at the two frequencies is the same. H No limitation.

[0185] Optionally, when the terminal supports single sideband offset, the terminal can offset the CW frequency upward or downward. For example, taking the CW frequency as f0, the terminal can offset the CW frequency between f0-f0 by frequency offset. H or f0+f H Uplink information is transmitted at two frequency points. In this way, single sideband offset can improve the frequency resource utilization, but the hardware complexity of the terminal may be higher than that of double sideband offset. H No limitation.

[0186] In some embodiments, the SSB offset includes at least one of: an upward SSB offset, a downward SSB offset, and a bidirectional SSB offset. Optionally, when the terminal supports bidirectional SSB offset, the terminal can perform an upward SSB offset or a downward SSB offset. That is, when the terminal supports bidirectional SSB offset, the terminal can support both an upward SSB offset and a downward SSB offset.

[0187] It can be understood that upward shift may mean that the frequency of the reflected signal reflected by the terminal to the CW is higher than the frequency of the CW, and downward shift may mean that the frequency of the reflected signal reflected by the terminal to the CW is lower than the frequency of the CW.

[0188] For example, the first information can be used to indicate that the terminal supports single sideband offset and supports bidirectional single sideband offset. At this time, the terminal can support single sideband offset of the CW frequency upward, and can also support single sideband offset of the CW frequency downward.

[0189] In some embodiments, the first information may also be used to indicate the frequency offset supported by the terminal. Optionally, the frequency offset supported by the terminal may be in terms of frequency as the minimum magnitude, or in terms of frequency units as the minimum magnitude. Optionally, the frequency domain unit may be a predefined frequency domain bandwidth. Optionally, the frequency domain unit may be the bandwidth of a subchannel. Optionally, the frequency domain unit may also be the bandwidth of multiple subchannels, or a preset bandwidth.

[0190] Optionally, the first information includes at least one of the following: a first frequency value, the first frequency value is used to indicate the maximum value of the frequency offset supported by the terminal; at least one second frequency value, the second frequency value is used to indicate the frequency offset supported by the terminal; a frequency range, the frequency range is used to indicate the frequency offset supported by the terminal within the frequency range; a first number of frequency domain units, the first number of frequency domain units is used to indicate the maximum number of frequency domain units supported by the terminal; at least one second number of frequency domain units, the number of frequency domain units is used to indicate the frequency domain unit offset supported by the terminal; a frequency domain unit range, the frequency domain unit range is used to indicate the frequency domain unit offset within the frequency domain unit range supported by the terminal; an offset parameter, the offset parameter includes a reference offset f b , increment offset f h The incremental number k, the offset parameter is used to indicate that the frequency offset supported by the terminal is f b +k*f h .

[0191] For example, when the first information includes a first frequency value and the first frequency value is 400kHz, the frequency offset of the terminal can be less than or equal to 400kHz, and the frequency of the reflected electromagnetic wave supported by the terminal can be higher and / or lower than the frequency of the received CW 0-400kHz. For example, if the terminal supports bidirectional single sideband offset, the terminal can support an upward single sideband offset of 0-400kHz and a downward single sideband offset of 0-400kHz. If the frequency of CW is f0, the frequency reflected by the terminal can be f0-f H or f0+f H , where 0≤f H ≤400kHz, or 0 <f H <400kHz.

[0192] For another example, if the first information includes multiple second frequency values, and the multiple second frequency values ​​are 100 kHz and 200 kHz, respectively, the frequency offset value supported by the terminal can be fixed at 100 kHz or 200 kHz. Taking the terminal supporting upward single sideband offset as an example, if the CW frequency is f0, the frequency reflected by the terminal can be f0+100 kHz or f0+200 kHz.

[0193] As another example, if the first information includes a frequency range, and the frequency range is 200-400kHz, then the frequency offset that the terminal can support can be in the range of 200-400kHz. Taking the case where the terminal supports downward single sideband offset, if the CW frequency is f0, then the frequency reflected by the terminal can be f0-f H , where 200kHz≤f H ≤400kHz.

[0194] As another example, when the first information includes the first number of frequency domain units, and the number of frequency domain units is equal to 4, the terminal can support a frequency offset of 0-4 frequency domain units. Taking the terminal supporting double-sideband offset as an example, if the CW frequency is f0, then the frequency reflected by the terminal can be f0-f H and f0+f H , where 0≤f H ≤4*f n , f n is the bandwidth of a frequency domain unit.

[0195] In addition, the example in which the first information includes the number of second frequency domain units and the frequency domain unit range is similar to the above example in which the first information includes the first frequency value and the second frequency value, and is not described in detail here.

[0196] It can also be understood that the first information may include multiple information bits or multiple information bit fields, and each information bit or each information bit field may be used to indicate corresponding information.

[0197] For example, an information bit field in the first information can be used to indicate the type of frequency offset supported by the terminal, such as the terminal can support bidirectional single-sideband offset, an information bit field in the first information can be used to indicate the value of the frequency offset supported by the terminal, such as the terminal can support frequency offset of 2 or 4 frequency domain units, or, there can also be an information bit field in the first information for indicating the offset parameter.

[0198] For another example, the first information may include an information bit field for indicating the frequency offset values ​​supported by the terminal, and another information bit field for indicating the signs of the frequency offset values ​​supported by the terminal. The signs of the frequency offset values ​​can, to a certain extent, indicate the types of frequency offsets supported by the terminal. For example, when the value of an information bit field in the first information is 00, the information bit field can be used to indicate that the sign of the corresponding frequency offset value is default; when the value of the information bit field is 01, the information bit field can be used to indicate that the sign of the corresponding frequency offset value is +; when the value of the information bit field is 10, the information bit field can be used to indicate that the sign of the corresponding frequency offset value is -; and when the value of the information bit field is 11, the information bit field can be used to indicate that the sign of the corresponding frequency offset value is ±. Furthermore, when the sign of the frequency offset value is +, it can be indicated that the terminal supports upward single sideband offset; when the sign of the frequency offset value is -, it can be indicated that the terminal supports downward single sideband offset; when the sign of the frequency offset value is ±, it can be indicated that the terminal supports bidirectional single sideband offset; and when the sign of the frequency offset value is default, it can be indicated that the terminal supports double sideband offset.

[0199] In some embodiments, the network device receives first information sent by the terminal. Optionally, the network device determines the frequency offset capability of the terminal based on the first information. Optionally, the network device determines the frequency offset type and frequency offset amount supported by the terminal based on the first information.

[0200] In some embodiments, the first information may be “capability indication information”, “terminal offset capability”, “offset capability information”, etc. The embodiment of the present disclosure does not limit the name of the first information.

[0201] Step S2102: The network device sends second information to the terminal.

[0202] In some embodiments, the network device may semi-statically or dynamically indicate to the terminal whether to apply a frequency offset during reflection through the second information. Alternatively, the network device may semi-statically or dynamically indicate to the terminal the frequency offset that can be applied through the second information.

[0203] In some embodiments, the second information is used to indicate or configure at least one of: whether to apply a frequency offset to the reflection of the CW; and the frequency offset applied to the reflection of the CW.

[0204] Optionally, the frequency offset applied to the reflection of the CW indicated by the second information may include one or more frequency offset offsets. For example, the frequency offset applied to the reflection of the CW indicated by the second information may include +200kHz and -300kHz. In this case, when the terminal reflects the CW, it may shift the CW upward by 200kHz or downward by 300kHz.

[0205] Optionally, when the second information is used to indicate whether a frequency offset is applied to the reflection of the CW and / or the frequency offset applied to the reflection of the CW, the terminal can perform the corresponding operation only the next time the CW is reflected. For example, the second information is used to indicate that a frequency offset is not applied to the CW reflection, then the terminal may not perform a frequency offset on the CW frequency the next time the CW is received.

[0206] Optionally, when the second information is used to configure whether to apply a frequency offset to the reflection of the CW and / or the frequency offset applied to the reflection of the CW, the terminal can perform corresponding operations on all CWs received after receiving the second information. For example, the second information is used to configure the application of a frequency offset to the reflection of the CW, and the value of the applied frequency offset is ±300kHz, then the terminal performs a double-sideband offset of 300kHz on each CW received thereafter.

[0207] Optionally, the frequency offset applied to the reflection of the CW indicated by the second information may be a frequency offset supported by the terminal.

[0208] For example, if the network device determines based on the first information that the terminal supports a bidirectional single sideband offset of 0-400kHz, the frequency offset applied to the reflection of the CW indicated by the second information may be, for example, +300kHz. Accordingly, when the terminal reflects the CW, it may shift the CW upward by 300kHz based on the second information. Alternatively, if the network device determines based on the first information that the terminal supports a downward single sideband offset of 2 or 4 frequency domain units, the frequency offset applied to the reflection of the CW indicated by the second information may be, for example, -2*f n , accordingly, when the terminal reflects the CW, it can shift the CW downward by 2*f according to the second information n , where f n is the bandwidth of a frequency domain unit.

[0209] In some embodiments, the terminal receives second information sent by the network device. Optionally, the terminal determines a frequency offset to be applied to the reflection of the CW based on the second information. Optionally, the terminal determines a frequency offset to be applied to the reflection of the CW based on the second information.

[0210] In some embodiments, the second information may be "frequency offset indication information", "frequency offset configuration information", etc. The embodiment of the present disclosure does not limit the name of the second information.

[0211] Step S2103: The network device sends third information to the terminal.

[0212] In some embodiments, the third information is used to indicate the first subchannel. Optionally, the first subchannel is a subchannel of an uplink channel transmitted by the terminal. Optionally, the third information is used to schedule or configure the subchannel of the uplink channel transmitted by the terminal.

[0213] Optionally, the uplink channel transmitted by the terminal may include data information and / or control information. Optionally, the uplink channel may include at least one of the following: PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), and PRACH (Physical Random Access Channel).

[0214] It is understood that the terminal transmitting an uplink channel may specifically refer to the terminal using at least one of the above-mentioned uplink channels to transmit corresponding data or signaling. For example, after receiving a CW, the terminal may modulate the CW so that the electromagnetic waves sent by the terminal can carry data information and / or control information, such as uplink data and UCI (Uplink Control Information).

[0215] In some embodiments, the subchannel indicated by the third information may be determined by the network device based on the frequency offset applied by the terminal and the subchannel through which the first device transmits the CW. The frequency offset applied by the terminal may be configured or indicated by the network device through the second information, and the subchannel through which the first device transmits the CW may be indicated by the network device through the fourth information.

[0216] In some embodiments, the first sub-channel may include one or more sub-channels. Optionally, the first sub-channel is a sub-channel in a resource pool. Optionally, the first sub-channel may include one or more sub-channels in a resource pool. Optionally, the resource pool may be configured by a network device or defined by a protocol.

[0217] In some embodiments, the terminal receives third information sent by the network device. Optionally, the terminal determines a sub-channel for transmitting an uplink channel based on the third information.

[0218] For example, after receiving the third information, the terminal may modulate the received CW and reflect it to the sub-channel indicated by the third information, thereby achieving transmission of the uplink channel.

[0219] In some embodiments, the third information may be "uplink resource indication information", "first sub-channel indication information", etc. The embodiment of the present disclosure does not limit the name of the third information.

[0220] Step S2104: The network device sends fourth information to the first device.

[0221] In some embodiments, the fourth information indicates the subchannel on which the frequency of the first CW is transmitted. Alternatively, the fourth information may be determined by the network device based on a frequency offset applied by the terminal to the CW reflection and the subchannel of the terminal's uplink transmission channel. Alternatively, the fourth information may be determined by the network device based on a preconfigured rule. For example, the subchannel indicated by the fourth information may be all subchannels in a resource pool or one or more pre-set subchannels.

[0222] In some embodiments, the fourth information may include at least one of the following: a third subchannel, the third subchannel includes at least one subchannel; a fourth subchannel, the fourth subchannel is determined based on the first subchannel and the frequency offset applied by the terminal to the reflection of the CW, and the first subchannel is the subchannel of the terminal transmission uplink channel; a preset rule, the preset rule is used to determine the fifth subchannel for sending the first CW.

[0223] Optionally, the third sub-channel, the fourth sub-channel, and the fifth sub-channel are all sub-channels in the resource pool. Optionally, the third sub-channel, the fourth sub-channel, and the fifth sub-channel may each include one or more sub-channels.

[0224] Optionally, the third sub-channel can be determined by the network device according to a pre-configured rule. The third sub-channel can include all sub-channels in the resource pool, or all sub-channels with even indexes in the resource pool. The embodiment of the present disclosure does not limit the method for determining the third sub-channel.

[0225] Optionally, the fourth subchannel can be determined by the network device when the frequency offset applied by the terminal for reflection of CW and the subchannel of the terminal transmission uplink channel are known. For example, after the network device has configured or scheduled the terminal through the second information and the third information, the corresponding fourth subchannel can be determined based on the frequency offset indicated by the second information and the subchannel indicated by the third information.

[0226] Optionally, the preset rule may be specified by a protocol or configured by a network device, and is not limited in this embodiment of the present disclosure. For example, the first device may determine, based on the preset rule, that an even-indexed subchannel in the resource pool is the fifth subchannel, and transmit the first CW on the frequency corresponding to the fifth subchannel.

[0227] It is worth noting that the fourth information including the aforementioned subchannel may specifically include the index of the aforementioned subchannel. For example, the fourth information including the third subchannel may mean that the fourth information includes the index of one or more subchannels in the third subchannel. For example, if the resource pool includes 10 subchannels and the subchannel indexes are 0-9, and the third subchannel is an even-numbered subchannel in the resource pool, the fourth information may include 0, 2, 4, 6, and 8.

[0228] In some embodiments, a first device receives fourth information sent by a network device. Optionally, the first device determines, based on the fourth information, a subchannel on which a frequency for transmitting the first CW is located. Optionally, the first device transmits the first CW at any frequency or a reference frequency in the third subchannel. Optionally, the first device transmits the first CW at any frequency or a reference frequency in the fourth subchannel. Optionally, the first device determines a fifth subchannel based on a preset rule and transmits the first CW at any frequency or a reference frequency in the fifth subchannel.

[0229] In some embodiments, the fourth information may be "CW configuration information", "sub-channel configuration information", "sub-channel indication information", etc. The embodiment of the present disclosure does not limit the name of the fourth information.

[0230] Step S2105: The network device sends fifth information to the first device.

[0231] In some embodiments, the fifth information is used to determine the frequency at which the first CW is transmitted. Alternatively, the fifth information may be used to determine the subchannel on which the frequency of the first CW is transmitted. The first device may transmit the first CW at any frequency or at a reference frequency within the determined subchannel. Alternatively, the fifth information is information required by the first device to determine the frequency at which the first CW is transmitted.

[0232] In some embodiments, the fifth information includes at least one of the following: a frequency offset applied by the terminal to the reflection of the CW; a subchannel of the uplink channel transmitted by the terminal; and a frequency offset capability of the terminal to reflect the CW.

[0233] Optionally, the frequency shift capability of the terminal to reflect the CW may be determined according to the first information.

[0234] Optionally, the frequency offset applied by the terminal to the reflection of the CW may be the frequency offset indicated by the second information, or may be a frequency offset determined by the terminal itself and reported to the network device, which is not limited in this embodiment of the present disclosure.

[0235] Optionally, the sub-channel of the uplink channel transmitted by the terminal may be a sub-channel indicated by the third information, or may be a sub-channel determined by the terminal itself and reported to the network device, which is not limited in the embodiment of the present disclosure.

[0236] In one example, when the network device does not send the second information and the third information to the terminal, the fifth information may only include the frequency offset capability of the terminal reflecting CW, and the first device may determine the frequency of sending the first CW based on the frequency offset capability of the terminal reflecting CW.

[0237] In another example, the network device sends the second information and the third information to the terminal, and the fifth information may include the frequency offset applied by the terminal to the reflection of the CW (i.e., the frequency offset indicated by the second information) and the sub-channel of the uplink channel transmitted by the terminal (i.e., the sub-channel indicated by the third information). The first device may determine the corresponding sub-channel for sending the first CW based on the frequency offset applied by the terminal to the reflection of the CW and the sub-channel of the uplink channel transmitted by the terminal.

[0238] In another example, the network device sends the third information to the terminal but does not send the second information. The fifth information may include the sub-channel of the terminal's uplink transmission channel (i.e., the sub-channel indicated by the third information) and the frequency offset capability of the terminal reflecting CW. The first device can determine the sub-channel for sending the first CW based on the sub-channel of the terminal's uplink transmission channel and the frequency offset capability of the terminal reflecting CW.

[0239] In some embodiments, the first device receives fifth information sent by the network device. Optionally, the first device determines a frequency for sending the first CW based on the fifth information.

[0240] In some embodiments, the fifth information may be "frequency parameter information", "terminal related information", etc. The embodiment of the present disclosure does not limit the name of the fifth information.

[0241] Step S2106: The first device sends a first CW to the terminal.

[0242] In some embodiments, the first device transmits a first CW on one or more frequencies. Optionally, the one or more frequencies are distributed across one or more subchannels. Optionally, the first device transmits the first CW on one or more subchannels, for example, at a reference frequency point across multiple subchannels. Optionally, the first device transmits the first CW on all subchannels in a resource pool. Optionally, the first device transmits the first CW on some subchannels in the resource pool.

[0243] In some embodiments, the first device may determine the subchannel on which the frequency of transmitting the first CW is located based on the fourth information. For alternative implementations, see the corresponding description in step S2104 and are not further described here. For example, the first device may determine the third subchannel and / or the fourth subchannel as the subchannel on which the frequency of transmitting the first CW is located. Alternatively, the first device may determine the fifth subchannel as the subchannel on which the frequency of transmitting the first CW is located based on a preset rule.

[0244] In some embodiments, the first device may determine the frequency of sending the first CW, or the sub-channel where the frequency is located, based on the fifth information. Its optional implementation methods can refer to the corresponding description in step S2105 and will not be repeated here. For example, the first device may determine the sub-channel where the frequency of sending the first CW is located based on the frequency offset applied by the terminal to the reflection of the CW and the sub-channel of the terminal transmission uplink channel. Alternatively, the first device determines the sub-channel where the frequency of sending the first CW is located based on the sub-channel of the terminal transmission uplink channel and the frequency offset capability of the terminal reflecting the CW. Alternatively, the first device determines the frequency of sending the first CW based on the frequency offset capability of the terminal reflecting the CW.

[0245] In some embodiments, the first device may independently determine the frequency or subchannel on which to transmit the first CW. For example, the first device may transmit the first CW at a reference frequency point for each subchannel in the resource pool. Alternatively, the first device may determine the subchannel in the resource pool on which to transmit the first CW based on a preconfigured rule.

[0246] In some embodiments, a terminal receives a first CW transmitted by a first device. Optionally, the terminal receives the first CW on at least one frequency. Optionally, the terminal receives the first CW on one or more subchannels. Optionally, the terminal receives the first CW on one or more subchannels in a resource pool.

[0247] In some embodiments, the terminal determines that the subchannel at the frequency where the first CW is received is the second subchannel. Optionally, the second subchannel is a subchannel in a resource pool. Optionally, the second subchannel includes one or more subchannels.

[0248] In other embodiments, the terminal may determine the second subchannel based on the frequency offset applied to the reflection of the CW and the subchannel of its uplink transmission channel, and then receive the first CW only on the second subchannel. The terminal may not expect to receive the first CW on subchannels other than the second subchannel.

[0249] In step S2107 , the terminal determines a frequency offset applied to the reflection of the CW.

[0250] In some embodiments, the terminal may determine whether to apply a frequency offset to the CW. Optionally, the terminal determines whether to apply a frequency offset based on the second information. The terminal's determination not to apply a frequency offset to the CW may be equivalent to, to a certain extent, determining that the frequency offset applied to the reflection of the CW is 0.

[0251] In some embodiments, the terminal may determine the frequency offset applied to the reflection of the CW according to the second information. Optional implementations thereof may refer to the corresponding description in step S2102 and are not described in detail here.

[0252] In some embodiments, the terminal may also determine the frequency offset applied to the reflection of the first CW based on the subchannel on which the first CW is received and the subchannel indicated by the third information. That is, the terminal may determine the frequency offset applied to the reflection of the CW based on the first subchannel and the second subchannel.

[0253] For example, if the terminal receives the first CW on the subchannel with index 4, and the index of the first subchannel indicated by the third information is 2, the terminal can determine that the frequency offset applied to the reflection of the CW is -2*f n , where fn is the bandwidth of a frequency domain unit, and the bandwidth of a frequency domain unit is equal to the bandwidth of a subchannel.

[0254] In some embodiments, the terminal may also determine the frequency offset to be applied to the CW reflection based on its frequency offset capability for reflecting the CW. For example, if the terminal supports a bidirectional single-sideband offset of 0 to 400 kHz, the terminal may select any value between ±0 and 400 as the frequency offset to be applied.

[0255] In some embodiments, the terminal may reflect the first CW to the network device based on the frequency offset applied to the CW reflection. Optionally, before reflecting the first CW to the network device, the terminal may modulate the first CW and transmit the modulated electromagnetic wave to the network device. The frequency of the modulated electromagnetic wave is within the bandwidth of the first subchannel, and the modulated electromagnetic wave may carry an uplink channel.

[0459] FIG7A is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG7A , the embodiment of the present disclosure relates to an information processing method, which includes:

[0460] In step S7101, the device reports its backscattering frequency offset capability to the network.

[0461] The device may be, for example, a terminal, an IoT device, etc., which is not limited in the embodiments of the present disclosure.

[0462] In some embodiments, the offset capability may be represented in multiple forms. For example, the offset method may be divided into double-sideband offset and single-sideband offset.

[0463] In the case of double-sideband offset, the device shifts the CW frequency f0 upward and downward by fH respectively. Therefore, the device transmits uplink information at two frequencies: f0-fH and f0+fH. The transmitted uplink information is the same.

[0464] With single-sideband offset, the device shifts the CW frequency f0 upward or downward by fH, so the device transmits uplink information at the frequency point f0-fH or f0-fH. Single-sideband offset can improve frequency resource utilization, but the device hardware complexity is higher.

[0465] The device's support for single-sideband frequency offset may include the following implementation methods:

[0466] (1) The device indicates an offset frequency value, such as 400 kHz, indicating that the range of frequency offset that the device can support is 0 to 400 kHz.

[0467] Furthermore, the device needs to indicate whether the offset is an upward, downward, or bidirectional offset. When it is indicated as an upward offset, it means that the device can support the reflected electromagnetic wave frequency to be 0 to 400 kHz higher than the CW frequency. For example, if the CW frequency is f0, then the frequency reflected by the device is f0 + fH, where 0 < fH < 400 kHz; when indicated as downward, it means that the device can support the reflected electromagnetic wave frequency to be 0 to 400 kHz lower than the CW frequency; when indicated as bidirectional, it means that the device can support the reflected electromagnetic wave frequency to be 0 to 400 kHz higher or lower than the CW frequency. Of course, the above upward, downward, and bidirectional frequency offsets can be represented by + and - signs. It can be understood that the "bidirectional offset" here is not the same as the above "double-sideband offset". The bidirectional offset here means that the device can perform single-sideband offset upward or downward.

[0468] (2) The device indicates one or more offset frequency values, such as 100 kHz, 200 kHz..., indicating that the frequency offset values that the device can support are fixed at 100 kHz and 200 kHz. Similarly, there are distinctions of upward, downward, and bidirectional.

[0469] (3) The device indicates a frequency range, such as 200 kHz to 400 kHz, indicating that the range of frequency offset that the device can support is 200 kHz to 400 kHz. Similarly, there are distinctions of upward, downward, and bidirectional.

[0470] (4) The device indicates the number K of frequency domain units of the supported offset, such as K = 4, indicating that the device can support frequency offsets of 0 to 4 frequency domain units (that is, the frequency offset is in the smallest granularity of frequency domain units). The frequency domain unit can be a pre-defined size of frequency domain bandwidth or just the bandwidth of a sub-channel. Similarly, there are distinctions of upward, downward, and bidirectional.

[0471] (5) The device indicates one or more supported offset frequency units, K1, K2. For example, 2 and 4 indicate that the device can support fixed frequency offset values ​​of 2 and 4 frequency units, respectively. Similarly, there are distinctions between upward, downward, and bidirectional.

[0472] (6) The device indicates the range of the number of frequency domain units of the supported offset, for example, 2 to 4, which means that the device can support frequency offset of 2 to 4 frequency domain units. Similarly, there is a distinction between upward, downward, and bidirectional.

[0473] (7) The device indicates the reference offset f of the supported offsets b and increment the offset f h The number of increments k. The increment offset f h The value of can be equal to the width of the subchannel. Indicates that the frequency offset that the device can support is f b +k*f h , that is, the device will be at f0+f b +k*f h Upward reflection. Similarly, there are upward, downward, and bidirectional reflections.

[0474] For devices that support double-sideband offset, the following implementations may be included:

[0475] (1) The device indicates an offset frequency value, such as 400kHz, which means that the frequency offset range supported by the device is 0 to 400kHz. For example, if the CW frequency is f0, then the frequency reflected by the device is f0-f H and f0+f H Two frequency points. <fH<400kHz

[0476] (2) The device indicates one or more offset frequency values, such as 100kHz, 200kHz, etc., indicating that the frequency offset values ​​supported by the device are fixed at 100kHz and 200kHz. For example, if the CW frequency is f0 at 100kHz, the frequencies reflected by the device are at f0-100kHz and f0+100kHz.

[0477] (3) The device indicates a frequency range, such as 200kHz to 400kHz, which means that the frequency offset range supported by the device is 200kHz to 400kHz. For example, if the CW frequency is f0, then the frequency reflected by the device is f0-f H and f0+f HTwo frequency points. 200khz <f H <400kHz.

[0478] (4) The device indicates the number of frequency domain units of supported offsets, K. For example, K = 4, which means the device can support frequency offsets of 0 to 4 frequency domain units (that is, the frequency offset is based on the frequency domain unit as the minimum granularity). For example, if the CW frequency is f0, then the frequency reflected by the device is f0-k*f u and f0+k*f u Two frequency points. Among them, f u is the bandwidth of a frequency domain unit, and k is a value in {0,1,2,..,K}.

[0479] (5) The device indicates one or more supported offset frequency domain units K1, K2, for example 2, 4, indicating that the frequency offset value supported by the device is fixed to 2 frequency domain units, 4 frequency domain units. For example, if the CW frequency is f0, then the frequency reflected by the device is f0-k*f u and f0+-k*f u Two frequency points. Among them, f u is the bandwidth of a frequency domain unit, and k is a value in {K1, K2,…}.

[0480] (6) The device indicates the range of the number of frequency domain units of the supported offset, for example, 2 to 4, which means that the device can support a frequency offset of 2 to 4 frequency domain units. For example, if the CW frequency is f0, then the frequency reflected by the device is f0-k*f u and f0+-k*f u Two frequency points. Among them, f u The bandwidth of a frequency domain unit. k is a value in {2,3,4}.

[0481] (7) The device indicates the base offset f of the supported offsets b and increment the offset f h The number of increments k. The increment offset f h The value of can be equal to the width of the subchannel. Indicates that the frequency offset that the device can support is f b +k*f h , that is, the device will be at f0+f b +k*f h Up and f0-f b -k*f h reflection.

[0482] FIG7B is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG7B , the embodiment of the present disclosure relates to an information processing method, which includes:

[0483] In step S7201, the network configures (semi-statically) or instructs (dynamically) the device whether to apply an offset in backscattering, and the value or range of the applicable offset.

[0484] In some embodiments, if the network specifies a sub-channel for transmitting an uplink channel for the device, when the network indicates multiple offset values ​​or an offset covering a spectrum range to the device, it means that the device must attempt to receive CW at multiple frequency positions included in the offset of the reference frequency point where the indicated uplink transmission sub-channel is used.

[0485] FIG7C is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG7C , the embodiment of the present disclosure relates to an information processing method, which includes:

[0486] Step S7301: The network configures / instructs each device on the sub-channel to be used for uplink transmission.

[0487] In some embodiments, the device may independently select one or more sub-channels from the resource pool.

[0488] In some embodiments, the network can configure / instruct the CW node whether to send CW on the frequency corresponding to each sub-channel. The network can instruct the CW node to send CW on the frequency where a certain sub-channel is located, send CW on the frequencies where multiple sub-channels are located, send CW on the frequencies where all sub-channels in the resource pool are located, or indicate a pattern of sub-channels for sending CW to the CW node.

[0489] If the device modulates and reflects the carriers on all subchannels of a CW in the same manner, then transmitting the CW on multiple or all subchannels can achieve frequency domain diversity gain at the receiving end.

[0490] Assuming that the resource pool has 10 sub-channels (the resource pool can be protocol-defined or network-configured), the following examples can be given:

[0491] The following examples (1)-(6) all correspond to the case where the device supports single sideband offset capability.

[0492] (1) The network receives a bidirectional backscatter frequency offset capability of 2 subchannels from device A. The network instructs device A to apply an offset of (+ / -) 0 / 1 / 2 subchannels. The network schedules device A and instructs it to use subchannel 3 for its UL transmission. The network instructs the CW node to send a CW on subchannel 3 (i.e., the device uses an offset of 0 for this transmission).

[0493] (2) The network receives a bidirectional backscatter frequency offset capability of 2 subchannels from device A. The network instructs device A to apply an offset of (+ / -) 0 / 1 / 2 subchannels. The network schedules device A and instructs it to use subchannel 3 for its UL transmission. The network instructs the CW node to send a CW on subchannel 4 (i.e., the device uses an offset of -1 for this transmission).

[0494] (3) The network receives a backscatter frequency offset capability of 2 subchannels in both directions from device A and a backscatter frequency offset capability of 1 subchannel in both directions from device B. The network instructs device A to apply an offset of (+ / -) 0 / 1 / 2 subchannels. The network instructs device B to apply an offset of (+ / -) 0 / 1 subchannels. The network schedules devices A and B, instructing device A to use subchannel 3 for its UL transmission and device B to use subchannel 5 for its UL transmission. The network instructs the CW node to send a CW on subchannel 5. (That is, device A uses an offset of -2 for this transmission, and device B uses an offset of 0.)

[0495] (4) The network receives a backscatter frequency offset capability of 2 subchannels in both directions from device A, an offset capability of 1 subchannel in both directions from device B, and an offset capability of 1 subchannel upward from device C. The network indicates that the applicable offset for device A is + / 2 subchannels, the network indicates that the applicable offset for device B is +0 / 1 subchannels, and the network indicates that the applicable offset for device C is 0 subchannel. The network schedules devices A / B / C but does not indicate the corresponding uplink transmission resources. Devices A / B / C can independently determine the subchannels used for uplink transmission in the resource pool. The network can instruct the CW node to send CWs in a pattern that alternates one subchannel, for example, sending CWs on subchannels 0 / 3 / 6. In this case, device A transmits on subchannels 2 / 5 / 8, device B transmits on subchannels 1 / 4 / 7, and device C transmits on subchannels 0 / 3 / 6. Three devices can be separated on different sub-channels through different offsets, and each device can transmit information on three sub-channels, achieving frequency diversity.

[0496] (5) The network receives that device A's backscatter frequency offset capability is two subchannels in both directions, and the network instructs device A to apply an offset of zero subchannels. The network schedules device A but does not indicate the corresponding uplink transmission resources. Device A can independently determine the subchannels used for uplink transmission in the resource pool. The network can instruct the CW node to send CWs on all 10 subchannels in the resource pool. Device A will perform backscattering on all 10 subchannels in the resource pool, achieving frequency diversity. Of course, the network can also instruct the CW node to send CWs only on some subchannels, for example, on subchannels 0 / / 2 / / 4 and 6 / 8. In this way, the uplink channels that device A may use are subchannels 0 / 2 / 4 / 6 / 8.

[0497] (6) If the network does not indicate to the CW node the subchannel frequency information of the CW, the CW node transmits the CW on the pre-set default subchannel in the resource pool. (At this time, the network determines whether to schedule the device based on the CW node's default transmission situation to avoid device conflicts.)

[0498] The following example corresponds to the case where the device supports double-sideband offset capability.

[0499] (7) The network receives that device A's backscatter frequency offset capability is 2 subchannels. The network indicates that device A can apply an offset of 0 / 1 / 2 subchannels. The network schedules device A and indicates that the resources used for its UL transmission include subchannel 3 (because the device may actually transmit on 2 subchannels, the base station may only indicate one of them). The network instructs the CW node to transmit CW on subchannel 3. That is, the offset applied by device A is 0

[0500] (8) The network receives a backscatter frequency offset capability of 2 subchannels from device A. The network instructs device A to apply an offset of 0, 1, or 2 subchannels. The network schedules device A, indicating that the resources used for its UL transmission include subchannel 4. The network instructs the CW node to transmit a CW on subchannel 3. This means that device A applies an offset of 1 and will transmit on subchannels 2 and 4.

[0501] (9) The network receives a backscatter frequency offset capability of 2 subchannels from device A. The network instructs device A to apply an offset of 2 subchannels. The network schedules device A (but does not need to specify the channel to use for uplink transmission, as the base station only indicates the offset). The network instructs the CW node to transmit CW on subchannel 3. That is, device A will transmit on subchannel 1 / 5.

[0502] (10) The network receives a backscatter frequency offset capability of 2 subchannels from device A and a backscatter frequency offset capability of 1 subchannel from device B. The network instructs device A to apply an offset of 0 / 1 / 2 subchannels. The network instructs device B to apply an offset of 0 / 1 subchannels. The network schedules devices A and B, instructing device A to use subchannel 4 for its UL transmission and subchannel 5 for device B. The network instructs the CW node to transmit CW on subchannel 5. Device B will then transmit on subchannel 5 (applying an offset of 0), and device A will transmit on subchannels 4 and 6 (applying an offset of 1).

[0503] (11) The network receives a backscatter frequency offset capability of 2 subchannels from device A, an offset capability of 2 subchannels from device B, and an offset capability of 1 subchannel from device C. The network instructs device A to apply an offset of 2, device B to apply an offset of 1, and device C to apply an offset of 0 (since the network specifies a unique offset for each device, no additional resources need to be specified). The network instructs the CW node to send CW on subchannels 2 / 7, device A to transmit the uplink channel on subchannels 0 / 4 / 5 / 9, device B to transmit on subchannels 1 / 3 / 6 / 8, and device C to transmit on subchannel 2 / 7. The three devices can be separated on different subchannels through different offsets, and each device can transmit information on three subchannels, achieving the effect of frequency diversity.

[0504] In some other possible embodiments, the network may not need to explicitly indicate the CW node, but instead allow the CW node to determine the frequency domain position of its CW transmission according to various information.

[0505] In one embodiment, when the uplink transmission resource of the device is specified by the network, the network may inform the CW node of the uplink subchannel index and offset capability of the device, allowing the CW node to determine the frequency domain position of the CW transmission.

[0506] In one embodiment, when the uplink transmission resources of the device are not assigned by the network, the base station informs the CW node of the offset capability of the device, allowing the CW node to independently determine the frequency domain position for sending the CW.

[0507] The above solution allows CW nodes to send CWs only at necessary frequency locations, effectively saving energy and reducing network interference. Alternatively, frequency diversity can be used to improve uplink information transmission performance in scenarios where coverage enhancement is required.
