[0046] Embodiments of the present disclosure provide an information processing method, a communication device, a communication system, a storage medium and a program product.

[0047] In a first aspect, embodiments of the present disclosure provide an information processing method, wherein the method is performed by a first device, and the method comprises: receiving first signaling sent by a second device; and determining whether to set a first time interval between multiple uplink transmissions according to the first signaling.

[0048] In the above embodiment, the first device receives the first signaling sent by the second device before performing the multiple uplink transmissions, so as to determine whether to set the first time interval between the multiple uplink transmissions according to the first signaling, so that the first device and the second device reach an agreement on whether to set the first time interval between the multiple uplink transmissions, thereby reducing the case that the multiple uplink transmissions are disturbed or interrupted due to the inconsistency of information between the first device and the second device, improving the reception performance of the data of the multiple uplink transmissions of the first device, and reducing the processing complexity of the second device.

[0049] In some embodiments of the first aspect, in some embodiments, the first signaling comprises at least one of:

[0050] a first type of indication, used to indicate whether the first time interval needs to be set between the multiple uplink transmissions;

[0051] a second type of indication, used to indicate the duration of the first time interval set between the multiple uplink transmissions;

[0052] a third type of indication, used to indicate the position of the first time interval set between the multiple uplink transmissions.

[0053] In the above embodiment, since the first type of indication is used to indicate whether the first time interval is set between the multiple uplink transmissions, compared with the first type of indication, the second type of indication can not only indicate whether the first time interval is set between the multiple uplink transmissions, but also indicate the duration of the first time interval set; the third type of indication can not only indicate whether the first time interval is set between the multiple uplink transmissions, but also indicate the setting position of the first time interval. In this way, the indication information carried by the first signaling can be flexibly selected according to the actual application scenario, so that more information related to the first time interval is indicated by the first signaling, while the signaling overhead of the first signaling is reduced.

[0054] In some embodiments of the first aspect, in some embodiments, the first type of indication has a first value, indicating that the first time interval is set between the multiple uplink transmissions; the first type of indication has a second value, indicating that the first time interval is not set between the multiple uplink transmissions.

[0055] In the above embodiment, different values of the first type of indication are used to respectively indicate whether the first time interval is set between the multiple uplink transmissions or not, which has the characteristics of simple implementation.

[0056] In some embodiments of the first aspect, in some embodiments, the method further comprises: the first signaling comprises the first type of indication and the first type of indication has a first value, and the duration of the first time interval is determined according to a protocol agreement.

[0057] In the above embodiment, in a case where the first signaling includes the first type of indication with the first value, the first device determines the length of the first time interval according to a protocol agreement. In this way, without increasing the amount of information carried by the first signaling, the first device can set the first time interval between multiple uplink transmissions based on the length of the first time interval agreed in advance by the protocol.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the second type of indication includes at least one of: length information used to indicate a length value; a first index used to indicate the length of the first time interval; and indexes of different alternative lengths are different.

[0059] In the above embodiment, by carrying the length information in the second type of indication, the length of the first time interval can be indicated by the length information, which has the feature of simple implementation. Alternatively, by carrying the first index in the second type of indication, the length of the first time interval can be indicated by the first index, while the bit overhead can also be effectively reduced.

[0060] In combination with some embodiments of the first aspect, in some embodiments, the third type of indication includes at least one of:

[0061] a second index indicating a distribution pattern of the first time interval in a time domain position;

[0062] a bit map used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0063] In the above embodiment, by carrying the second index in the third type of indication, the distribution pattern of the first time interval in the time domain position can be indicated by the second index, so that the setting position of the first time interval between multiple uplink transmissions can be determined based on the distribution of the first time interval in the preconfigured distribution pattern. In this way, the setting position of the first time interval can be indicated, and the bit overhead can also be effectively reduced. Alternatively, by carrying the bit map in the third type of indication, the setting of the first time interval between any two adjacent uplink transmissions in multiple uplink transmissions can be more dynamically indicated by the bit map.

[0064] In combination with some embodiments of the first aspect, in some embodiments, the bit map includes N bits, where the nth bit is used to indicate whether there is a first time interval after the nth uplink transmission; N is a positive integer greater than 1; n is a positive integer, and n is less than or equal to N.

[0065] In the above embodiment, a way of indicating the position of the first time interval set between multiple uplink transmissions by using a bit map is provided, which has the feature of simple implementation.

[0066] In some embodiments of the first aspect, in some embodiments, the bit map comprises N-1 bits, wherein an nth bit is used to indicate whether there is a first time interval between an nth uplink transmission and an (n+1)th uplink transmission; N is a positive integer greater than 1; n is a positive integer, and n is less than N.

[0067] In the above embodiments, another way of indicating the position of setting a first time interval between multiple uplink transmissions by using a bit map is provided, which can reduce the size of the bit map required to be carried by the first signaling on the basis of simple implementation.

[0068] In some embodiments of the first aspect, in some embodiments, the first signaling comprises a first transmission configuration; and determining, according to the first signaling, whether to set a first time interval between multiple uplink transmissions comprises determining, according to the first transmission configuration, whether to set a first time interval between multiple uplink transmissions.

[0069] In the above embodiments, the first transmission configuration can be carried in the first signaling to multiplex the first transmission configuration of multiple uplink transmissions to indicate whether a first time interval needs to be set between multiple uplink transmissions; and no additional information related to the first time interval needs to be carried in the first signaling. In this way, the first device and the second device can reach an agreement on whether to set a first time interval between multiple uplink transmissions, and the situation that multiple uplink transmissions are disturbed or interrupted due to inconsistent information between the first device and the second device can be reduced; and the signaling overhead of the first signaling can be reduced.

In this way, when the second device configures time domain resources for multiple uplink transmissions, a time interval is reserved between multiple time domain resources to ensure the interval between multiple uplink transmissions, and the resource configuration information of multiple uplink transmissions carried by the first signaling is used to indicate the setting of the first time interval, so that no additional information needs to be carried in the first signaling to indicate.

[0073] In the above embodiments, when the multiple uplink transmissions are uplink repetitions, the third index indicating the number of uplink repetitions carried by the first sending configuration is used to determine whether to set the first time interval between the multiple uplink repetitions. In this way, the existing third index indicating the number of uplink repetitions is reused to indicate whether to set the first time interval, thereby reducing the bit overhead.

At the same time, based on the parameters of one uplink transmission, the first device can also determine the number of uplink transmissions required to complete the transmission of the to-be-transmitted data, so as to determine whether to set the first time interval according to the number of uplink transmissions.

[0078] In some embodiments of the first aspect, in some embodiments, the first time interval is greater than or equal to a second time interval, and the second time interval is a time interval of frequency switching of a continuous wave (CW) signal of the first device.

[0079] In the above embodiment, the first time interval between the multiple uplink transmissions is greater than or equal to a time interval required for frequency switching of the CW signal of the first device, so that the frequency switching of the CW signal occurs within the first time interval between the multiple uplink transmissions, so that none of the multiple uplink transmissions of the first device is segmented at the physical layer, and the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device is reduced.

Further, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, or the like).

[0177] The first device 101 as illustrated in FIG. 1A can be any device that wirelessly communicates using a backscatter transmission mechanism.

[0178] As shown in FIG. IB, FIG. IB is a schematic diagram illustrating wireless communication based on a backscatter transmission mechanism, according to an example embodiment. The backscatter transmission mechanism can be a wireless communication mechanism using the principle of radio frequency signal backscatter for modulation and transmission with extremely low power consumption. A reader sends a physical layer signal to an ambient IoT device. The physical layer signal can be an alternating current signal such as a pulse signal.

[0179] In some embodiments, the physical layer signal is used to provide energy for the ambient IoT device to transmit a signal. Thus, the physical layer signal can be referred to as an energizing signal or a triggering signal. Illustratively, when the energizing signal reaches the ambient IoT device, a portion of the energizing signal can be reflected, and the ambient IoT device can adjust the match between the receiving antenna and the impedance according to the information to be transmitted, enhance the reflection of the incident energizing signal, and modulate the sensed data obtained by the ambient IoT device onto the reflected signal to complete the transmission of the data. This process is similar to a mirror, and compared to other communication technologies, the backscatter transmission does not require complex radio frequency structures, reduces the use of power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and other devices, and does not require complex baseband processing. Thus, the backscatter transmission can simplify the design of the ambient IoT device and significantly reduce the cost of the ambient IoT device node. The ambient IoT device is an IoT device that can work in an environment. The environment can include the signal energy of the aforementioned wireless signal, and can also include other environmental capabilities such as geothermal energy and / or light energy.

[0180] Here, the device that sends the physical layer signal to the ambient IoT device to trigger the ambient IoT device to return a reflected signal can be referred to as an anchor point of a reader of the ambient IoT device.

[0181] It is worth noting that the ambient IoT device is a device that uses the backscatter transmission mechanism for wireless communication, and other devices can also use the backscatter transmission mechanism for wireless communication in specific implementations.

[0182] The anchor point or reader of the ambient IoT device can be a network node of a wireless communication network, such as an access network device, a relay node (or intermediate node), or a terminal, etc.

[0183] As shown in FIG. 1C, which is a diagram of devices using three backscatter transmission mechanisms for wireless communication, according to an example embodiment. Devices using backscatter transmission mechanisms for wireless communication can be classified into three types:

[0184] Device A: no energy storage, cannot independently generate signals and / or amplify signals, and can only perform backscatter transmission.

[0185] Device B: has energy storage, cannot independently generate signals, and can only perform backscatter transmission. The use of stored energy can include amplification of backscatter signals.

[0186] Device C: has energy storage and can independently generate signals, i.e., has active Radio Frequency (RF) components for transmission.

[0187] It should be noted that each device in FIG. 1C has two grids, where the first grid indicates whether the device has the ability to independently generate signals, and the second grid indicates whether the device has the ability to store energy. When the grid of a device is a grid without filling, it means that the device does not have the corresponding ability of the grid; when the grid of a device is a grid with filling, it means that the device has the corresponding ability of the grid.

[0188] In some embodiments, Ambient IoT technology can be applied in various communication scenarios, such as large-scale warehouse inventory, sensor networks, etc. Correspondingly, Ambient IoT devices need to support information reading, writing, or performing other commands, etc.

[0189] In some embodiments, in the design of ambient IoT, non-activate devices, i.e., devices A and devices B, which do not have the ability to transmit radio frequency by themselves, need to obtain transmission energy through backscatter.

[0190] In the application scenario of tag inventory, the design of ambient IoT devices can refer to Radio Frequency Identification (RFID). As shown in Table 1, in RFID, inventory is performed by relying on the following command set.

[0191] Table 1

[0192] In some scenarios of ambient IoT, e.g. base station as reader and tag as ambient IoT device, the corresponding inventory command and the reply of the ambient IoT device can still be carried by a channel such as a downlink physical shared channel (PDSCH) or an uplink physical shared channel (PUSCH). As shown in FIG. 1D, FIG. 1D is a schematic diagram illustrating an inventory process based on an ambient IoT device according to an example embodiment.

[0193] In some embodiments, for a tag, after receiving a Query command, the tag enters an arbitrate state, which can be regarded as a holding state of the tag, and sets a corresponding counter value according to a Q value in the Query command. The tag reduces the counter value by 1 each time a QueryRep command is received, and when the counter value is 0, the tag switches to a reply state and backscatters a RN16 (16-bit random number). If a confirmation message (ACK) is further received, it is confirmed that the tag is successfully accessed; otherwise, if an invalid ACK or an ACK carrying an error RN16 is received, or until time T2, the corresponding ACK is not received, the tag returns to the arbitrate state. In some embodiments, for uplink transmission (Device to Reader, D2R) in ambient IoT, in order to enhance reliability and uplink coverage, a corresponding repetition can be configured for D2R transmission. Currently, the following two repetition mechanisms are supported:

[0194] (1) Bit-level repetition: each bit in a transmission block (TB) is repeated N times, and then a corresponding encoding and modulation process is performed.

[0195] (2) TB-level repetition: each TB is transmitted multiple times, and the received signals can be combined at the receiving end to obtain gain.

[0196] The repetition involved in the embodiments of the present disclosure is TB-level repetition.

[0197] In some embodiments, since passive devices in ambient IoT only support backscattering based on continuous wave (CW) signals, they do not support actively generating signals. Therefore, there are three ways to transmit the CW signals as to how to transmit the CW signals. As shown in FIG. 1E, FIG. 1E is a schematic diagram of three ways of transmitting the CW signals according to an example embodiment.

[0198] (1) Single-tone transmission: that is, the CW signal is only transmitted on a certain frequency point of the R2D system bandwidth; as shown in (a) of FIG. 1E.

[0199] (2) Single-tone transmission and CW signal frequency switching: the CW signal is transmitted on a first frequency point in a time period and on a second frequency point in the next time period. As shown in (b) of FIG. 1E.

[0200] (3) Multi-tone transmission: the CW signal is transmitted on multiple frequency points (for example, 2 frequency points) in the system bandwidth. As shown in (c) of FIG. 1E.

[0201] For the scenario of supporting the frequency switching of the CW signal, since the frequency switching of the CW signal requires a certain processing time, if the device continuously transmits uplink, it can cause a "break" phenomenon at the middle position of the data packet transmission, which can affect the reception performance and complexity of the uplink transmission. As shown in FIG. 1F, FIG. 1F is a schematic diagram of uplink transmission breakage caused by frequency switching of the CW signal according to an example embodiment.

[0202] FIG. 2A is an interaction schematic diagram I of an information processing method according to an example embodiment. As shown in FIG. 2A, the embodiments of the present disclosure relate to an information processing method, which is used in the communication system 100, and the method comprises:

[0203] In step S2101, the second device transmits first signaling to the first device.

[0204] In some embodiments, the first device receives the first signaling transmitted by the second device.

[0205] In some embodiments, the first device can be a wireless device without a power supply module, a wireless device with weak power supply capability of the power supply module, a wireless device with a power supply module but the power supply module has lost the power supply capability, or any wireless device supporting backscattering communication.

[0213] In some embodiments, the second device can be any network device located in a trust domain of a mobile communication network.

[0214] In some embodiments, the second device can be any network device located in a trust domain of a mobile communication network, and such a second device can access the mobile communication network through a network exposure function or the like.

[0215] In some embodiments, the second device can be a Reader of the first device.

[0216] In some embodiments, the second device sends a first signal to the first device.

[0217] In some embodiments, the first signal can include, but is not limited to, a CW signal. It can be understood that the second device is a Continuous Wave Node (CWN) of the first device. It is worth noting that, in the embodiments of the present disclosure, the CWN of the first device and the Reader of the first device are the same node.

[0218] In some embodiments, the first signal provides energy for uplink transmission of the first device.

[0219] In some embodiments, the first signal can be a physical layer signal sent according to a preset sequence, which can not carry any information content.

[0220] It can be understood that the first signal can be a simple excitation signal and can not carry any information.

[0221] In some embodiments, the first information carries the first signaling.

[0222] The first signal can be a signal carrying information content. After receiving the first signal, the first device can extract the first signaling carried on the first signal by decoding the first signal.

[0223] In some embodiments, the first device has a backscatter communication capability.

[0224] In some embodiments, the first signaling is used by the first device to determine whether to set the first time interval between the multiple uplink transmissions.

[0225] In some embodiments, the first signaling is used by the first device to determine the duration of the first time interval set between the multiple uplink transmissions.

[0226] In some embodiments, the first signaling is used by the first device to determine the setting position of the first time interval between the multiple uplink transmissions.

[0227] It should be noted that the first device receives the first signaling sent by the second device before performing the multiple uplink transmissions, so as to determine, according to the first signaling, whether to set the first time interval between the multiple uplink transmissions, the duration of the set first time interval, and / or the setting position of the first time interval, so that the first device and the second device reach an agreement on the related settings of the first time interval between the multiple uplink transmissions, thereby reducing the situation that the multiple uplink transmissions are disturbed or interrupted due to the inconsistency of information between the first device and the second device, improving the reception performance of the data of the multiple uplink transmissions of the first device, and reducing the processing complexity of the second device.

[0228] In some embodiments, the first signaling includes at least one of the following:

[0229] The first type of indication is used to indicate whether the first time interval needs to be set between the multiple uplink transmissions.

[0230] The second type of indication is used to indicate the duration of the first time interval set between the multiple uplink transmissions.

[0231] The third type of indication is used to indicate the position of the first time interval set between the multiple uplink transmissions.

[0232] It can be understood that the first signaling can include at least one of the first type of indication, the second type of indication, and the third type of indication, so as to use the above indications to enable the first device to determine whether the first time interval needs to be set between the multiple uplink transmissions, a length of the set first time interval, and / or a set position of the first time interval, so that the second device can control the multiple uplink transmissions of the first device according to the frequency switching of the CW signal to reduce the "break" between the multiple uplink transmissions of the first device.

[0233] In some embodiments, the first type of indication has a first value, indicating that the first time interval needs to be set between the multiple uplink transmissions; and the first type of indication has a second value, indicating that the first time interval does not need to be set between the multiple uplink transmissions.

[0234] Here, the first type of indication includes one indication bit; and the first value and the second value can be different bit values of the indication bit. The specific values of the first value and the second value can be set according to actual needs, and embodiments of the present disclosure do not limit this. In some embodiments, the first value can be 1, and the second value can be 0.

[0235] It should be noted that embodiments of the present disclosure can carry one indication bit in the first signaling, and use different bit values of the indication bit to indicate whether the first time interval needs to be set between the multiple uplink transmissions. In this case, the length of the first time interval can be a length agreed by a protocol.

[0236] In some embodiments, the second type of indication includes at least one of the following: length information for indicating a length value; a first index for indicating a length value of the first time interval; and indexes of different alternative lengths are different.

[0237] It should be noted that the second type of indication can not only be used to indicate the length of the set first time interval, but also be used to indicate whether the first time interval is set between the multiple uplink transmissions.

[0238] It can be understood that, in a case where the length value of the first time interval indicated by the second type of indication is 0, it is indicated that the first time interval does not need to be set between the multiple uplink transmissions. In a case where the length of the first time interval indicated by the second type of indication is greater than 0, it is indicated that the first time interval needs to be set between the multiple uplink transmissions.

[0239] For the second type of indication, there can be two implementation manners.

[0240] In a first implementation manner, the second type of indication includes length information, and the length information is used to indicate the length value of the first time interval.

[0241] It should be noted that the length information can include multiple bits, and the length value of the first time interval is indicated by bit values of the multiple bits.

[0242] In a second implementation, the second type of indication includes a first index, and the first index is used to indicate a time length of the first time interval.

[0243] It should be noted that a plurality of candidate time lengths of the first time interval can be pre-configured, and the plurality of candidate time lengths correspond to different indexes. According to the first index carried by the second type of indication, a candidate time length corresponding to the first index is determined as the time length of the first time interval.

[0244] In some embodiments, the third type of indication includes at least one of the following: a second index, the second index indicating a distribution pattern of the first time interval in a time domain position; and a bit map, the bit map being used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0245] It should be noted that through the third type of indication, a position at which the first time interval is set between a plurality of uplink transmissions is indicated, so that the first time interval can be set between the plurality of uplink transmissions according to different frequency hopping patterns of the CW signal.

[0246] There can be two implementation manners for the third type of indication.

[0247] In a first implementation, the third type of indication includes a second index, and the second index indicates a distribution pattern of the first time interval in a time domain position.

[0248] It should be noted that a plurality of distribution patterns of the first time interval in a time domain position can be pre-configured, and the plurality of distribution patterns correspond to different indexes. Thus, according to the second index carried by the third type of indication, a distribution pattern of the first time interval corresponding to the second index is determined, and a position at which the first time interval is set between a plurality of uplink transmissions is determined according to the distribution pattern of the first time interval.

[0249] In a second implementation, the third type of indication includes a bit map, and the bit map is used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0250] It should be noted that each bit in the bit map can map a setting condition of the first time interval at a position between a plurality of uplink transmissions.

[0251] In some embodiments, the bit map includes N bits, where an nth bit is used to indicate whether there is the first time interval after an nth uplink transmission; N is a positive integer greater than 1; and n is a positive integer, n being less than or equal to N.

[0252] In some embodiments, the bit map includes N-1 bits, where an nth bit is used to indicate whether there is the first time interval between an nth uplink transmission and an (n+1)th uplink transmission; N is a positive integer greater than 1; and n is a positive integer, n being less than N.

[0253] In some embodiments, the first signaling comprises a first transmission configuration, and the first transmission configuration is used by the first device to determine whether to set the first time interval between the multiple uplink transmissions.

[0254] It should be noted that the first signaling can comprise the first transmission configuration, and the first transmission configuration can be a transmission configuration of the multiple uplink transmissions of the first device. It can be understood that the first device can determine whether to set the first time interval between the multiple uplink transmissions according to the transmission configuration of the multiple uplink transmissions.

[0255] It should be noted that in some embodiments, in the case that the first signaling comprises the first transmission configuration, any one of the aforementioned first type of instruction to the third type of instruction can not be included. In this case, the first transmission configuration can not only indicate the transmission configuration of the multiple uplink transmissions of the first device, but also indicate the related configuration of the first time interval between the multiple uplink transmissions. In this way, the first transmission configuration of the multiple uplink transmissions is multiplexed to indicate whether the first time interval needs to be set between the multiple uplink transmissions; and it is not necessary to additionally carry the related information indicating the first time interval in the first signaling.

[0256] For example, in the case that the first transmission configuration indicates that the number of uplink transmissions of the first device is 1, the first device can determine not to set the first time interval between the multiple uplink transmissions according to the first transmission configuration.

[0257] In some embodiments, the first signaling can comprise at least one of the first type of instruction, the second type of instruction, and the third type of instruction on the basis of comprising the first transmission configuration.

[0258] In some embodiments, the first transmission configuration comprises at least one of the following: a time domain position of the multiple uplink transmissions; a parameter of one uplink transmission; and a third index used to indicate the number of uplink repetitions.

[0259] It should be noted that the multiple uplink transmissions of the first device can comprise at least one of the following: first type of multiple uplink transmissions, which are multiple segmented transmissions for one data packet; and second type of multiple uplink transmissions, which are uplink repetitions for one TB.

[0260] For the first type of multiple uplink transmissions, the first transmission configuration can comprise at least one of the following: a time domain position of the multiple uplink transmissions; and a parameter of one uplink transmission.

[0261] It can be understood that the second device can configure multiple time domain resources for the multiple uplink transmissions of the first device; and use the first transmission configuration to carry information used to indicate the time domain position of the multiple uplink transmissions, so that the first device performs the multiple uplink transmissions based on the configured time domain resources of the multiple uplink transmissions.

[0262] It is worth noting that in this case, the time domain position of the multiple uplink transmissions can also be used to indicate whether a first time interval needs to be set between the multiple uplink transmissions. It can be understood that if the time domain positions of the multiple uplink transmissions are separated, it means that the first time interval needs to be set between the multiple uplink transmissions; if the time domain positions of the multiple uplink transmissions are connected, it means that the first time interval does not need to be set between the multiple uplink transmissions.

[0263] The second device can carry information indicating the parameters of the one uplink transmission by using the first sending configuration, so that the first device performs segmentation processing on the data to be transmitted based on the parameters of the one uplink transmission to obtain at least one TB to be transmitted.

[0264] In some embodiments, in the case that the second device does not configure multiple time domain resources for the multiple uplink transmissions of the first device, the first device can determine the number of the multiple uplink transmissions based on the parameters of the one uplink transmission in the first sending configuration; and thus determine whether the first time interval needs to be set between the multiple uplink transmissions according to the number of the multiple uplink transmissions. In some embodiments, the parameters of the one uplink transmission include at least one of the following: the TB size of the one uplink transmission; and the duration of the one uplink transmission.

[0265] It can be understood that the second device indicates the TB size of the one uplink transmission and / or the duration of the one uplink transmission by using the first sending configuration, so that the first device performs segmentation on the data to be transmitted based on the above-mentioned parameters to obtain at least one TB to be transmitted. Thus, ambiguity about the transmission time length of the uplink transmission between the first device and the second device can be reduced.

[0266] For the second type of multiple uplink transmissions, the first sending configuration can include a third index, which is used to indicate the number of uplink repeated transmissions.

[0267] It can be understood that the second device can configure the number of uplink repeated transmissions of the first device by using the third index, so that the first device performs the multiple uplink transmissions according to the configured number of uplink repeated transmissions.

[0268] The number of multiple uplink repeated transmissions can be pre-configured, and the indexes corresponding to different numbers are different. Thus, the number corresponding to the third index carried by the first sending configuration is determined as the number of uplink repeated transmissions.

[0269] It is worth noting that in the case that the number of uplink repeated transmissions indicated by the third index is greater than the third value, the first device needs to determine whether to set the first time interval between the multiple uplink transmissions. In the case that the number of uplink repeated transmissions indicated by the third index is equal to the third value, the first device does not need to set the first time interval. Here, the third value can be 1.

[0270] In some embodiments, the signaling type of the first signaling is used to indicate the number of uplink repeated transmissions.

[0271] It should be noted that the signaling type of the first signaling can implicitly indicate the number of uplink repeated transmissions. It can be understood that different types of first signaling correspond to different numbers of uplink repeated transmissions. Thus, the second device can indicate the number of uplink repeated transmissions of the first device by sending different types of first signaling to the first device; in this way, the third index does not need to be carried in the first signaling to indicate the specific number of uplink repeated transmissions.

[0272] In some embodiments, the frequency switching of the CW signal of the first device occurs at a third device, and the first signaling is used to indicate that a first time interval needs to be set between multiple uplink transmissions; or, the CW signal of the first device does not perform frequency switching, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions; or, the frequency switching of the CW signal of the first device occurs at different third devices, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0273] Here, the third device is the transmitting device of the CW signal; the CW signal provides the energy for the uplink transmission of the first device. It should be noted that in the embodiments of the present disclosure, the second device sends the first signal (the first signal includes but is not limited to the CW signal) to the first device, so that the first device can backscatter based on the first signal to perform multiple uplink transmissions to the second device. That is, the second device in the embodiments of the present disclosure can be the transmitting device of the CW signal, that is, the third device.

[0274] In the case where the frequency switching of the CW signal occurs at one third device, since the frequency switching of the CW signal needs a certain processing time, in order to reduce the break between multiple uplink transmissions of the first device caused by the frequency switching, the second device can send the first signaling to the first device, which is used to indicate that the first time interval needs to be set between multiple uplink transmissions.

[0275] In the case where the frequency switching of the CW signal occurs at different third devices, since the frequency switching of the CW signal is caused by the switching of multiple third devices, the first device cannot perceive the frequency switching of the CW signal in the time domain. Therefore, the second device can send the first signaling to the first device, which is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0276] In the case where the CW signal does not perform frequency switching, the second device can send the first signaling to the first device, which is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0277] It can be understood that the first device can send different first signaling to the first device according to different situations of the CW signal, so that the first device can determine whether to set the first time interval between multiple uplink transmissions according to different situations of the CW signal.

[0278] In some embodiments, the method further comprises at least one of:

[0279] The first device exists a third device, and the CW signal sent by the third device exists frequency switching, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval needs to be set between multiple uplink transmissions;

[0280] The first device exists a third device, and the CW signal sent by the third device does not exist frequency switching, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions;

[0281] The first device exists multiple third devices, and the frequencies of the CW signals sent by the multiple third devices are different, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0282] Here, the third device is the sending device of the CW signal of the first device, that is, the CWN. It should be noted that the second device and the third device can be the same node in the embodiment of the present disclosure. Alternatively, the second device can be one of the multiple third devices of the first device.

[0283] It can be understood that the second device sends different first signaling to the first device according to different situations of the CWN of the first device, so that the first device determines whether to set the first time interval between multiple uplink transmissions.

[0284] In step S2102, the first device determines whether to set the first time interval between multiple uplink transmissions.

[0285] In some embodiments, the first device determines whether to set the first time interval between multiple uplink transmissions according to the first signaling.

[0286] In some embodiments, the method further comprises that the first signaling comprises a first type of indication, and the first type of indication has a first value, and the first device determines the length of the first time interval according to a protocol agreement.

[0287] It should be noted that the first type of indication comprises an indication bit, and different bit values of the indication bit are used to indicate whether the first time interval needs to be set between multiple uplink transmissions. In the case that the first signaling comprises the first type of indication and the first type of indication has the first value, the first type of indication is used to indicate that the first time interval needs to be set between multiple uplink transmissions.

[0288] In this case, in order to facilitate the first device to set the first time interval between the multiple uplink transmissions, the length of the first time interval can be pre-configured by the protocol. Thus, the first device can determine the length of the first time interval according to the protocol agreement, and thus determine the time domain position of the multiple uplink transmissions.

[0289] In some embodiments, the method further includes that the first signaling includes a first type of indication and the first type of indication has a second value, and the first device does not set the first time interval between the multiple uplink transmissions.

[0290] In some embodiments, the method further includes that the first signaling includes a second type of indication, and the first device determines whether to set the first time interval between the multiple uplink transmissions and the length of the set first time interval according to the second type of indication.

[0291] It should be noted that the second type of indication includes at least one of the following: length information for indicating a length value; a first index for indicating the length value of the first time interval; and indexes of different alternative lengths are different.

[0292] In some embodiments, the first device determines whether to set the first time interval between the multiple uplink transmissions according to the second type of indication, including at least one of the following:

[0293] The length value indicated by the length information or the first index is greater than a fifth value, and it is determined to set the first time interval between the multiple uplink transmissions;

[0294] The length value indicated by the length information or the first index is equal to the fifth value, and it is determined not to set the first time interval between the multiple uplink transmissions.

[0295] Here, the fifth value can be 0. It can be understood that in the case that the length value of the first time interval indicated by the length information or the first index is equal to 0, it means that the first time interval does not need to be set between the multiple uplink transmissions; in the case that the length value of the first time interval indicated by the length information or the first index is greater than 0, it means that the first time interval needs to be set between the multiple uplink transmissions.

[0296] In some embodiments, the method further includes that the first signaling includes a third type of indication, and the first device determines whether to set the first time interval between the multiple uplink transmissions and the setting position of the first time interval according to the third type of indication.

[0297] It should be noted that the third type of indication includes at least one of the following: the second index, the second index indicating a distribution pattern of the first time interval in the time domain position; and a bit map, the bit map being used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions. It can be understood that, according to the third type of indication, a position where the first time interval is not set between the multiple uplink transmissions can be determined, which indicates that the first time interval does not need to be set between the multiple uplink transmissions.

[0298] In some embodiments, the first device determines, according to the first signaling, whether to set the first time interval between the multiple uplink transmissions, including: determining, according to the first transmission configuration, whether to set the first time interval between the multiple uplink transmissions; and wherein the first signaling includes the first transmission configuration.

[0299] It should be noted that the first transmission configuration can be a transmission configuration of the multiple uplink transmissions of the first device; and the first device can determine, according to the transmission configuration of the multiple uplink transmissions, whether to set the first time interval between the multiple uplink transmissions.

[0300] In some embodiments, determining, according to the first transmission configuration, whether to set the first time interval between the multiple uplink transmissions includes:

[0301] The time domain positions of the multiple uplink transmissions are separated, and it is determined to set the first time interval between the multiple uplink transmissions; and wherein the first transmission configuration includes the time domain positions of the multiple uplink transmissions.

[0302] Here, the multiple uplink transmissions of the first device can be multiple segmented transmissions for one data packet. And the second device can configure multiple time domain resources for the multiple uplink transmissions of the first device. It can be understood that, in the case where the first time interval needs to be set between the multiple uplink transmissions, the second device can reserve corresponding time intervals between the multiple time domain resources when configuring the multiple time domain resources, so as to ensure that there is the first time interval between the multiple uplink transmissions when the first device performs the multiple uplink transmissions based on the multiple time domain resources.

[0303] In the case where the time domain positions of the multiple uplink transmissions are separated, it is indicated that the second device reserves time intervals between the multiple time domain resources, and the first device can determine to set the first time interval between the multiple uplink transmissions.

[0304] In some embodiments, determining, according to the first transmission configuration, whether to set the first time interval between the multiple uplink transmissions includes:

[0305] The time domain positions of the multiple uplink transmissions are connected, and it is determined not to set the first time interval between the multiple uplink transmissions.

[0306] It can be understood that, in the case that the time domain positions of the multiple uplink transmissions are connected, it is indicated that there is no reserved time interval between the multiple time domain resources configured by the second device, and the first device can determine not to set the first time interval between the multiple uplink transmissions.

[0307] In some embodiments, determining, according to the first sending configuration, whether to set the first time interval between the multiple uplink transmissions comprises:

[0308] determining the number of uplink transmissions according to the parameter of one uplink transmission;

[0309] determining to set the first time interval between the multiple uplink transmissions when the number of uplink transmissions is greater than a fourth value; wherein the first sending configuration comprises the parameter of one uplink transmission.

[0310] Here, the multiple uplink transmissions of the first device can be multiple segmented transmissions of one data packet; and the second device does not configure multiple time domain resources for the multiple uplink transmissions of the first device. In this case, in order to reduce ambiguity between the first device and the second device about the transmission time length of the uplink transmission, the second device configures the parameter of one uplink transmission in the first sending configuration, so that the first device determines the number of uplink transmissions based on the parameter of one uplink transmission.

[0311] In some embodiments, determining to set the first time interval between the multiple uplink transmissions when the number of uplink transmissions is greater than a fourth value comprises:

[0312] The first signaling indicates that the first time interval needs to be set between the multiple uplink transmissions and the number of uplink transmissions is greater than a fourth value, and determining to set the first time interval between the multiple uplink transmissions.

[0313] Here, the fourth value can be 1. It should be noted that, in the case that the number of uplink transmissions is greater than 1, the first time interval indicated by the first signaling can take effect; in the case that the number of uplink transmissions is equal to 1, even if the first signaling indicates that the first time interval needs to be set, the first device does not need to set the first time interval.

[0314] In some embodiments, determining the number of uplink transmissions according to the parameter of one uplink transmission comprises: segmenting the to-be-transmitted data to obtain at least one to-be-transmitted TB according to the parameter of one uplink transmission; and determining the number of uplink transmissions according to the number of to-be-transmitted TBs.

[0315] It should be noted that the parameter of one uplink transmission can comprise at least one of the following: the TB size of one uplink transmission; and the duration of one uplink transmission. The first device can segment the to-be-transmitted data based on the TB size of one uplink transmission and / or the duration of one uplink transmission.

[0316] In some embodiments, the to-be-transmitted TB includes second information indicating whether there is a next uplink transmission.

[0317] It should be noted that the first device segments the to-be-transmitted data to obtain at least one to-be-transmitted TB packet; since the second device does not know the number of to-be-transmitted TBs, nor the number of multiple uplink transmissions of the first device; it is impossible for the second device to know whether the data packet obtained based on the received at least one TB is complete. Therefore, the first device carries second information in each to-be-transmitted TB, and uses the second information to indicate whether there is a next uplink transmission.

[0318] In some embodiments, according to the first sending configuration, determining whether to set the first time interval between the multiple uplink transmissions includes:

[0319] The third index indicates that the number of uplink repeated transmissions is greater than the third value, and it is determined to set the first time interval between the multiple uplink repeated transmissions; wherein the first sending configuration includes the third index, which is used to indicate the number of uplink repeated transmissions.

[0320] It should be noted that the multiple uplink transmissions of the first device in the embodiments of the present disclosure can be uplink repeated transmissions for one TB. The first device can determine the number of uplink repeated transmissions according to the third index; and thereby determine whether to set the first time interval between the multiple uplink repeated transmissions.

[0321] In some embodiments, the third index indicates that the number of uplink repeated transmissions is greater than the third value, and it is determined to set the first time interval between the multiple uplink repeated transmissions, including: the first signaling indicates that the first time interval needs to be set between the multiple uplink transmissions and the number of uplink repeated transmissions indicated by the third index is greater than the third value, and it is determined to set the first time interval between the multiple uplink repeated transmissions.

[0322] Here, the third value can be 1. It should be noted that in the case where the number of uplink repeated transmissions is greater than 1, the first signaling indicating the first time interval can take effect; in the case where the number of uplink repeated transmissions is equal to 1, even if the first signaling indicates that the first time interval needs to be set, the first device does not need to set the first time interval.

[0323] In some embodiments, according to the first signaling, determining whether to set the first time interval between the multiple uplink transmissions includes: the signaling type of the first signaling indicates that the number of uplink repeated transmissions is greater than the third value, and it is determined to set the first time interval between the multiple uplink repeated transmissions.

[0324] In some embodiments, the signaling type of the first signaling indicates a number of uplink repeated transmissions greater than the third value, and the determining of setting the first time interval between the multiple uplink repeated transmissions comprises: the first signaling indicates that the first time interval needs to be set between the multiple uplink repeated transmissions, and the signaling type of the first signaling indicates a number of uplink repeated transmissions greater than the third value, and the determining of setting the first time interval between the multiple uplink repeated transmissions.

[0325] It should be noted that the signaling type of the first signaling can implicitly indicate the number of uplink repeated transmissions. It can be understood that different types of first signaling correspond to different numbers of uplink repeated transmissions. The first device can determine the number of uplink repeated transmissions according to the signaling type of the received first signaling; and thereby determine whether to set the first time interval between the multiple uplink repeated transmissions.

[0326] Step S2103: The first device performs the multiple uplink transmissions.

[0327] In some embodiments, the first device performs the multiple uplink transmissions according to time domain positions of the multiple uplink transmissions,

[0328] It can be understood that the first device determines the time domain positions of the multiple uplink transmissions according to the first signaling; and thereby performs the multiple uplink transmissions based on the time domain positions of the multiple uplink transmissions.

[0329] In some embodiments, the first device performs the multiple uplink transmissions based on a CW signal.

[0330] It can be understood that after receiving the CW signal, the first device performs backscattering based on the CW signal to obtain a reflected signal; and carries the multiple TBs to be transmitted in the reflected signal to perform the multiple uplink transmissions to the second device.

[0331] In some embodiments, the term “information” can be mutually replaced with the terms “message”, “signal”, “signaling”, “report”, “configuration”, “indication”, “instruction”, “command”, “channel”, “parameter”, “field”, “data”, and the like.

[0332] In some embodiments, the term “sending” can be mutually replaced with the terms “transmitting”, “reporting”, “transmitting”, and the like.

[0333] The information processing method related to the embodiments of the present disclosure can include at least one of steps S2101 to S2103. For example, step S2101 in combination with step S2102 can be implemented as an independent embodiment, but is not limited thereto.

[0334] In some embodiments, step S2103 is optional, and one or more of the steps can be omitted or replaced in different embodiments. It can be understood that in the case where the second device is not the transmitting device of the CW signal of the first device, the first device does not have the ability to actively send the uplink transmission.

[0335] FIG. 2B is a second interaction diagram of an information processing method according to an exemplary embodiment. As shown in FIG. 2B, the embodiments of the present disclosure relate to an information processing method for a communication system 100, and the method includes:

[0336] In step S2201, the second device sends first signaling to the first device and the third device.

[0337] In some embodiments, the first device receives the first signaling sent by the second device.

[0338] In some embodiments, the third device receives the first signaling sent by the second device.

[0346] In some embodiments, the second device may be any network device located within the trusted domain of the mobile communication network, and such a second device may access the mobile communication network through network open functions, etc.

[0347] For example, the first device is an IoT device, and the second device may be an IoT server.

[0348] In some embodiments, the second device may be any network device located within the trust domain of the mobile communication network.

[0349] In some embodiments, the second device may be any network device located within the trusted domain of the mobile communication network, and such a second device may access the mobile communication network through network open functions, etc.

[0350] In some embodiments, the second device may be a reader of the first device.

[0351] In some embodiments, the third device may be any communication device that includes its own power supply module. For example, the third device may be various types of communication devices with their own batteries. These communication devices may include, but are not limited to, mobile phones, tablets, in-vehicle devices, wearable devices, smart home devices, and / or smart office devices.

[0352] In some embodiments, the third device may be the device that transmits the CW signal of the first device.

[0353] In some embodiments, the third device may be the CWN of the first device. It is worth noting that in this embodiment, the CWN of the first device and the Reader of the first device are not the same node.

[0354] In some embodiments, the CW signal provides the power for uplink transmission of the first device.

[0355] In some embodiments, the CW signal may be a physical layer signal sent in a preset sequence, which may not carry any information content.

[0356] It is understandable that the CW signal can be a simple excitation signal and may not carry any information.

[0357] In some embodiments, the first signaling is used by the first device to determine whether to set a first time interval between multiple uplink transmissions.

[0358] In some embodiments, the first signaling is used by the first device to determine the duration of a first time interval set between multiple uplink transmissions.

[0359] In some embodiments, the first signaling is used by the first device to determine a setting position of the first time interval between the multiple uplink transmissions.

[0360] It should be noted that the first device determines, before performing the multiple uplink transmissions, whether to set the first time interval between the multiple uplink transmissions, a length of the first time interval to be set, and / or a setting position of the first time interval according to the first signaling sent by the second device, so that the first device and the second device reach an agreement on the related settings of the first time interval between the multiple uplink transmissions, thereby reducing the situation that the multiple uplink transmissions are disturbed or interrupted due to the inconsistency of information between the first device and the second device, improving the reception performance of the data of the multiple uplink transmissions of the first device, and reducing the processing complexity of the second device.

[0361] In some embodiments, the first signaling is used by the third device to set the second time interval, which is a time interval of frequency switching of the CW signal of the first device.

[0362] It should be noted that the first signaling can indicate whether the first time interval needs to be set between the multiple uplink transmissions. The second device sends the first signaling to the third device, so that the third device can know the reservation of the first time interval between the multiple uplink transmissions of the first device based on the first signaling, and thus the third device implicitly knows the second time interval of the frequency switching of the CW signal based on the first signaling.

[0363] In some embodiments, the second time interval is less than or equal to the first time interval.

[0364] It can be understood that, in order to avoid the frequency switching of the CW signal affecting the multiple uplink transmissions of the first device, the third device can complete the frequency switching of the CW signal within the time range of the first time interval of the multiple uplink transmissions of the first device. Therefore, after the third device determines the length of the first time interval and the position of the first time interval between the multiple uplink transmissions according to the first signaling, the third device determines the position of the second time interval in the time domain and the length of the second time interval.

[0365] In some embodiments, the first signaling is used by the third device to determine the first information, and the first information includes at least one of the following: the length of the second time interval; a first time, the first time being a starting time of performing the frequency switching by the third device; a second time, the second time being a termination time of completing the frequency switching by the third device.

[0366] The first time is after a first uplink transmission of adjacent two uplink transmissions of the first device, and the second time is before a second uplink transmission of the adjacent two uplink transmissions; and the first time interval is set between the adjacent two uplink transmissions.

[0367] It should be noted that the first signaling implicitly indicates at least one of the length of the second time interval, the first time and the second time, so that the third device determines the second time interval of the frequency switching of the CW signal. In this way, the frequency switching of the CW signal of the first device occurs in the first time interval of the multiple uplink transmissions of the first device, thereby reducing the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device.

[0368] In some embodiments, the first signaling includes at least one of the following:

[0369] The first type of indication is used to indicate whether the first time interval needs to be set between the multiple uplink transmissions;

[0370] The second type of indication is used to indicate the length of the first time interval set between the multiple uplink transmissions;

[0371] The third type of indication is used to indicate the position of the first time interval set between the multiple uplink transmissions.

[0372] It can be understood that the first signaling can include at least one of the first type of indication, the second type of indication and the third type of indication, so that the above indications are used to enable the first device to determine whether the first time interval needs to be set between the multiple uplink transmissions, the length of the first time interval set and / or the set position of the first time interval; so that the second device can control the multiple uplink transmissions of the first device according to the frequency switching of the CW signal, so as to reduce the "break" between the multiple uplink transmissions of the first device.

[0373] In some embodiments, the first type of indication has a first value, indicating that the first time interval is set between the multiple uplink transmissions; and the first type of indication has a second value, indicating that the first time interval is not set between the multiple uplink transmissions.

[0374] Here, the first type of indication includes one indication bit; and the first value and the second value can be different bit values of the indication bit. The specific values of the first value and the second value can be set according to actual needs, and the embodiments of the present disclosure do not limit this. In some embodiments, the first value can be 1, and the second value can be 0.

[0375] It should be noted that the embodiments of the present disclosure can carry one indication bit in the first signaling, and use different bit values of the indication bit to indicate whether the first time interval needs to be set between the multiple uplink transmissions. In this case, the length of the first time interval can be a length agreed by the protocol.

[0376] In some embodiments, the second type of indication comprises at least one of: time length information, used to indicate a time length value; a first index, used to indicate a time length value of the first time interval; and indexes of different alternative time lengths.

[0377] It should be noted that the second type of indication can be used not only to indicate the time length of the set first time interval, but also to indicate whether the first time interval is set between multiple uplink transmissions.

[0378] It can be understood that, in a case where the second type of indication indicates that the time length value of the first time interval is 0, it means that the first time interval does not need to be set between multiple uplink transmissions. In a case where the second type of indication indicates that the time length of the first time interval is greater than 0, it means that the first time interval needs to be set between multiple uplink transmissions.

[0379] There can be two implementation manners for the second type of indication.

[0380] In a first implementation manner, the second type of indication comprises time length information, which is used to indicate the time length value of the first time interval.

[0381] It should be noted that the time length information can comprise multiple bits, and the bit values of the multiple bits are used to indicate the time length value of the first time interval.

[0382] In a second implementation manner, the second type of indication comprises a first index, which is used to indicate the time length of the first time interval.

[0383] It should be noted that a plurality of alternative time lengths of the first time interval can be pre-configured, and the alternative time lengths correspond to different indexes. According to the first index carried by the second type of indication, the alternative time length corresponding to the first index is determined as the time length of the first time interval.

[0384] In some embodiments, the third type of indication comprises at least one of: a second index, used to indicate a distribution pattern of the first time interval in a time domain position; and a bit map, used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0385] It should be noted that, by means of the third type of indication, the position of the first time interval set between multiple uplink transmissions is indicated, so that the first time interval can be set between multiple uplink transmissions according to different frequency hopping patterns of the CW signal.

[0386] There can be two implementation manners for the third type of indication.

[0387] In a first implementation manner, the third type of indication comprises a second index, which is used to indicate a distribution pattern of the first time interval in a time domain position.

[0388] It should be noted that a plurality of distribution patterns of the first time interval in the time domain position can be pre-configured, and the plurality of distribution patterns correspond to different indexes. Thus, according to the second index carried by the third type of indication, and according to the distribution pattern of the first time interval corresponding to the second index, the position of the first time interval between the multiple uplink transmissions is determined.

[0389] In a second implementation, the third type of indication includes a bitmap, and the bitmap is used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0390] It should be noted that each bit in the bitmap can map the setting of the first time interval at a position between multiple uplink transmissions.

[0391] In some embodiments, the bitmap includes N bits, where the nth bit is used to indicate whether there is a first time interval after the nth uplink transmission; N is a positive integer greater than 1; n is a positive integer, and n is less than or equal to N.

[0392] In some embodiments, the bitmap includes N-1 bits, where the nth bit is used to indicate whether there is a first time interval between the nth uplink transmission and the nth+1 uplink transmission; N is a positive integer greater than 1; n is a positive integer, and n is less than N.

[0393] In some embodiments, the first signaling includes a first transmission configuration, and the first transmission configuration is used by the first device to determine whether to set the first time interval between the multiple uplink transmissions.

[0394] It should be noted that the first signaling can include a first transmission configuration, and the first transmission configuration can be a transmission configuration of the multiple uplink transmissions of the first device. It can be understood that the first device can determine whether to set the first time interval between the multiple uplink transmissions according to the transmission configuration of the multiple uplink transmissions.

[0395] Notably, in some embodiments, the first signaling can only include the first transmission configuration. In this case, the first transmission configuration can not only indicate the transmission configuration of the multiple uplink transmissions of the first device, but also indicate the related configuration of the first time interval between the multiple uplink transmissions. In this way, the first transmission configuration of the multiple uplink transmissions is multiplexed to indicate whether the first time interval needs to be set between the multiple uplink transmissions; and no additional related information indicating the first time interval needs to be carried in the first signaling.

[0396] For example, in the case where the first transmission configuration indicates that the number of uplink transmissions of the first device is 1, the first device can determine, according to the first transmission configuration, that the first time interval is not set between the multiple uplink transmissions.

[0397] In some embodiments, the first signaling can further comprise at least one of the first indication, the second indication and the third indication based on the first transmission configuration.

[0398] In some embodiments, the first transmission configuration comprises at least one of: time domain positions of the multiple uplink transmissions; parameters of the single uplink transmission; and the third index, the third index being used to indicate the number of the uplink repeated transmissions.

[0399] It is to be noted that the multiple uplink transmissions of the first device can comprise at least one of: the first type of multiple uplink transmissions, the first type of multiple uplink transmissions being multiple segmented transmissions for one data packet; and the second type of multiple uplink transmissions, the second type of multiple uplink transmissions being uplink repeated transmissions for one TB.

[0400] For the first type of multiple uplink transmissions, the first transmission configuration can comprise at least one of: time domain positions of the multiple uplink transmissions; and parameters of the single uplink transmission.

[0401] It is to be understood that the second device can configure multiple time domain resources for the multiple uplink transmissions of the first device; and the first transmission configuration can carry information indicating the time domain positions of the multiple uplink transmissions, so that the first device performs the multiple uplink transmissions based on the configured multiple time domain resources of the multiple uplink transmissions.

[0402] It is to be noted that in this case, the time domain positions of the multiple uplink transmissions can also be used to indicate whether the first time interval needs to be set between the multiple uplink transmissions. It is to be understood that if the time domain positions of the multiple uplink transmissions are separated, it means that the first time interval needs to be set between the multiple uplink transmissions; and if the time domain positions of the multiple uplink transmissions are connected, it means that the first time interval does not need to be set between the multiple uplink transmissions.

[0403] The second device can use the first transmission configuration to carry information indicating the parameters of the single uplink transmission, so that the first device performs segmented processing on the data to be transmitted based on the parameters of the single uplink transmission, to obtain at least one TB to be transmitted.

[0404] In some embodiments, in the case that the second device does not configure multiple time domain resources for the multiple uplink transmissions of the first device, the first device can determine the number of the multiple uplink transmissions based on the parameters of the single uplink transmission in the first transmission configuration; and then determine whether the first time interval needs to be set between the multiple uplink transmissions according to the number of the multiple uplink transmissions.

[0405] In some embodiments, the parameters of the single uplink transmission comprise at least one of: a TB size of the single uplink transmission; and a duration of the single uplink transmission.

[0406] It can be understood that the second device indicates the TB size of the one-time uplink transmission and / or the duration of the one-time uplink transmission through the first sending configuration, so that the first device segments the data to be transmitted based on the parameters to obtain at least one TB to be transmitted. Thus, ambiguity about the transmission time length of the uplink transmission between the first device and the second device can be reduced.

[0407] For the second type of multiple uplink transmission, the first sending configuration can include a third index, the third index being used to indicate the number of uplink repeated transmissions.

[0408] It can be understood that the second device can configure the number of uplink repeated transmissions of the first device through the third index, so that the first device performs multiple uplink transmissions according to the configured number of uplink repeated transmissions.

[0409] The number of multiple uplink repeated transmissions can be pre-configured, and different numbers correspond to different indexes. Thus, according to the third index carried by the first sending configuration, the number corresponding to the third index is determined as the number of uplink repeated transmissions.

[0410] It is worth noting that the first device needs to determine whether to set the first time interval between multiple uplink transmissions only when the number of uplink repeated transmissions indicated by the third index is greater than the third value. When the number of uplink repeated transmissions indicated by the third index is equal to the third value, the first device does not need to set the first time interval. Here, the third value can be 1.

[0411] In some embodiments, the signaling type of the first signaling is used to indicate the number of uplink repeated transmissions.

[0412] It should be noted that the signaling type of the first signaling can implicitly indicate the number of uplink repeated transmissions. It can be understood that different types of first signaling correspond to different numbers of uplink repeated transmissions. Thus, the second device can indicate the number of uplink repeated transmissions of the first device by sending different types of first signaling to the first device; in this way, the third index does not need to be carried in the first signaling to indicate the specific number of uplink repeated transmissions.

[0413] In some embodiments, the frequency switching of the CW signal of the first device occurs at a third device, and the first signaling is used to indicate that the first time interval needs to be set between multiple uplink transmissions; or, the frequency switching of the CW signal of the first device does not occur, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions; or, the frequency switching of the CW signal of the first device occurs at a different third device, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0414] It should be noted that, in the case that the frequency switching of the CW signal occurs in a third device, since the frequency switching of the CW signal needs a certain processing time, in order to reduce the interruption between the multiple uplink transmissions of the first device caused by the frequency switching, the second device can send, to the first device, first signaling for indicating that the first time interval needs to be set between the multiple uplink transmissions.

[0415] In the case that the frequency switching of the CW signal occurs in different third devices, since the frequency switching of the CW signal is caused by the switching of multiple third devices, the first device cannot perceive the frequency switching of the CW signal in the time domain. Therefore, the second device can send, to the first device, first signaling for indicating that the first time interval does not need to be set between the multiple uplink transmissions.

[0416] In the case that the CW signal does not perform frequency switching, the second device can send, to the first device, first signaling for indicating that the first time interval does not need to be set between the multiple uplink transmissions.

[0417] It can be understood that the first device can send different first signaling to the first device according to different situations of the CW signal, so that the first device can determine whether to set the first time interval between the multiple uplink transmissions according to different situations of the CW signal.

[0418] In some embodiments, the method further includes at least one of the following:

[0419] In the case that the first device exists one third device and the CW signal sent by the third device has frequency switching, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval needs to be set between the multiple uplink transmissions.

[0420] In the case that the first device exists one third device and the CW signal sent by the third device does not have frequency switching, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval does not need to be set between the multiple uplink transmissions.

[0421] In the case that the first device exists multiple third devices and the CW signals sent by the multiple third devices have different frequencies, the first signaling is sent to the first device, and the first signaling is used to indicate that the first time interval does not need to be set between the multiple uplink transmissions.

[0422] Here, the third device is the sending device of the CW signal of the first device, that is, the CWN. It should be noted that the second device and the third device can be different nodes in the embodiments of the present disclosure.

[0423] It can be understood that the second device sends different first signaling to the first device according to different situations of the CWN of the first device, so that the first device determines whether to set the first time interval between the multiple uplink transmissions.

[0424] In step S2202, the first device determines whether to set a first time interval between multiple uplink transmissions.

[0425] In some embodiments, the optional implementation of step S2202 can refer to the optional implementation of step S2102 in FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which are not described herein again.

[0426] In step S2203, the third device sends a CW signal to the first device.

[0427] In some embodiments, the first device receives the CW signal sent by the third device.

[0428] In some embodiments, the CW signal provides energy for the uplink transmission of the first device.

[0429] In some embodiments, the third device sends the CW signal to the first device, including: determining, by the third device, a fourth sending configuration of the CW signal according to the first information; and sending, by the third device, the CW signal to the first device according to the fourth sending configuration.

[0430] It should be noted that the first information is determined by the third device based on the first signaling, and the first information includes at least one of: a length of the second time interval; a first time, the first time being a start time of performing frequency switching by the third device; and a second time, the second time being a termination time of completing frequency switching by the third device.

[0431] The third device determines the fourth sending configuration of the CW signal according to the first information, so that the frequency switching of the CW signal sent according to the fourth sending configuration is within the first time interval between the multiple uplink transmissions of the first device, thereby reducing the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device.

[0432] In step S2204, the first device performs multiple uplink transmissions.

[0433] In some embodiments, the optional implementation of step S2204 can refer to the optional implementation of step S2103 in FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which are not described herein again.

[0434] The information processing method related to the embodiments of the present disclosure can include at least one of steps S2201 to S2204. For example, step S2201 in combination with step S2202 can be implemented as an independent embodiment, and steps S2201 in combination with steps S2202 and S2204 can be implemented as an independent embodiment, but are not limited thereto.

[0435] In some embodiments, steps S2203 and S2204 are optional, and one or more of these steps can be omitted or replaced in different embodiments. It can be understood that, in the case that the first device does not receive the CW signal, the first device does not have the ability to actively send the uplink transmission; the multiple uplink transmissions can be performed after the CW signal is received.

[0436] In some embodiments, step S2203 is optional, and one or more of these steps can be omitted or replaced in different embodiments. It can be understood that, in the case that the second device sends the CW signal to the first device, the first device can perform the multiple uplink transmissions based on the CW signal sent by the second device, without the third device sending the CW signal to the first device.

[0437] FIG. 2C is an interaction diagram three of an information processing method according to an exemplary embodiment. As shown in FIG. 2B, the embodiments of the present disclosure relate to an information processing method for the communication system 100, and the method comprises:

[0438] In step S2301, the second device sends first signaling to the first device.

[0439] In some embodiments, the first device receives the first signaling sent by the second device.

[0440] In some embodiments, the first device can be a wireless device without a power supply module, a wireless device with weak power supply capability, a wireless device with a power supply module but the power supply module has lost the power supply capability, or any wireless device supporting backscatter communication.

[0441] In some embodiments, the first device can be any passive device, ambient energy device, ambient IoT device, or the like.

[0442] In some embodiments, the first device has backscatter communication capability.

[0443] Exemplarily, the first device can be the device A and / or the device B shown in FIG. 1C.

[0444] The second device can be any communication device containing a power supply module. Exemplarily, the second device can be various types of communication devices with a battery. For example, the communication device can include but is not limited to a mobile phone, a tablet computer, a vehicle-mounted device, a wearable device, a smart home device, and / or a smart office device.

[0445] The second device can include but is not limited to a server or an Application Function (AF).

[0446] In some embodiments, the second device can be any network device located in a trust domain of the mobile communication network.

[0447] In some embodiments, the second device can be any network device located in a trust domain of the mobile communication network, and the second device can access the mobile communication network through a network exposure function or the like.

[0448] Exemplarily, the first device is an IoT device, and the second device can be an IoT server.

[0449] In some embodiments, the second device can be any network device located in a trust domain of the mobile communication network.

[0450] In some embodiments, the second device can be any network device located in a trust domain of the mobile communication network, and the second device can access the mobile communication network through a network exposure function or the like.

[0451] In some embodiments, the second device can be a Reader of the first device.

[0452] In some embodiments, the first device has a backscatter communication capability.

[0453] In some embodiments, the first signaling is used by the first device to determine whether to set the first time interval between the multiple uplink transmissions.

[0454] In some embodiments, the first signaling is used by the first device to determine a length of the first time interval set between the multiple uplink transmissions.

[0455] In some embodiments, the first signaling is used by the first device to determine a setting position of the first time interval between the multiple uplink transmissions.

[0456] It should be noted that, before performing the multiple uplink transmissions, the first device receives the first signaling sent by the second device, and determines, according to the first signaling, whether to set the first time interval between the multiple uplink transmissions, a length of the first time interval set, and / or a setting position of the first time interval, so that the first device and the second device reach an agreement on the related settings of the first time interval between the multiple uplink transmissions, thereby reducing the situation that the multiple uplink transmissions are disturbed or interrupted due to the inconsistency of information between the first device and the second device, improving the reception performance of the data of the multiple uplink transmissions of the first device, and reducing the processing complexity of the second device.

[0457] In some embodiments, the first signaling includes at least one of the following:

[0458] a first type of indication, used to indicate whether the first time interval needs to be set between the multiple uplink transmissions;

[0459] The second type of indication is used to indicate a length of the first time interval set between the multiple uplink transmissions.

[0460] The third type of indication is used to indicate a position of the first time interval set between the multiple uplink transmissions.

[0461] It can be understood that the first signaling can include at least one of the first type of indication, the second type of indication, and the third type of indication, so as to use the above indications to enable the first device to determine whether the first time interval needs to be set between the multiple uplink transmissions, a length of the set first time interval, and / or a set position of the first time interval, so that the second device can control the multiple uplink transmissions of the first device according to a frequency switching condition of the CW signal to reduce a "break" between the multiple uplink transmissions of the first device.

[0462] In some embodiments, the first type of indication has a first value, indicating that the first time interval is set between the multiple uplink transmissions, and has a second value, indicating that the first time interval is not set between the multiple uplink transmissions.

[0463] Here, the first type of indication includes one indication bit, and the first value and the second value can be different bit values of the indication bit. The specific values of the first value and the second value can be set according to actual needs, and embodiments of the present disclosure do not limit this. In some embodiments, the first value can be 1, and the second value can be 0.

[0464] It should be noted that embodiments of the present disclosure can carry one indication bit in the first signaling, and use different bit values of the indication bit to indicate whether the first time interval needs to be set between the multiple uplink transmissions. In this case, the length of the first time interval can be a length agreed by a protocol.

[0465] In some embodiments, the second type of indication includes at least one of the following: length information used to indicate a length value; a first index used to indicate the length value of the first time interval; and indexes of different alternative lengths are different.

[0466] It should be noted that the second type of indication can be used not only to indicate the length of the set first time interval, but also to indicate whether the first time interval is set between the multiple uplink transmissions.

[0467] It can be understood that, in a case where the length value of the first time interval indicated by the second type of indication is 0, it is indicated that the first time interval does not need to be set between the multiple uplink transmissions. In a case where the length of the first time interval indicated by the second type of indication is greater than 0, it is indicated that the first time interval needs to be set between the multiple uplink transmissions.

[0468] There can be two implementation manners for the second type of indication.

[0469] In a first implementation, the second type of indication includes time length information, and the time length information is used to indicate a time length value of the first time interval.

[0470] It should be noted that the time length information can include multiple bits, and the bit values of the multiple bits are used to indicate the time length value of the first time interval.

[0471] In a second implementation, the second type of indication includes a first index, and the first index is used to indicate the time length of the first time interval.

[0472] It should be noted that a plurality of candidate time lengths of the first time interval can be preconfigured, and the plurality of candidate time lengths correspond to different indexes. According to the first index carried by the second type of indication, the candidate time length corresponding to the first index is determined as the time length of the first time interval.

[0473] In some embodiments, the third type of indication includes at least one of the following: a second index, the second index indicating a distribution pattern of the first time interval in the time domain position; and a bit map, the bit map being used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0474] It should be noted that through the third type of indication, the position of the first time interval set between multiple uplink transmissions is indicated, so that the first time interval can be set between multiple uplink transmissions according to different frequency hopping patterns of the CW signal.

[0475] There can be two implementations for the third type of indication.

[0476] In a first implementation, the third type of indication includes a second index, and the second index indicates a distribution pattern of the first time interval in the time domain position.

[0477] It should be noted that a plurality of distribution patterns of the first time interval in the time domain position can be preconfigured, and the plurality of distribution patterns correspond to different indexes. Thus, according to the second index carried by the third type of indication, the distribution pattern of the first time interval corresponding to the second index is determined, and the position of the first time interval set between multiple uplink transmissions is determined according to the distribution pattern of the first time interval corresponding to the second index.

[0478] In a second implementation, the third type of indication includes a bit map, and the bit map is used to determine whether the first time interval needs to be set between any two adjacent uplink transmissions.

[0479] It should be noted that each bit in the bit map can map the setting of the first time interval at a position between multiple uplink transmissions.

[0480] In some embodiments, the bit bitmap includes N bits, where the nth bit is used to indicate whether there is the first time interval after the nth uplink transmission; N is a positive integer greater than 1; n is a positive integer, n is less than or equal to N.

[0481] In some embodiments, the bit bitmap includes N-1 bits, where the nth bit is used to indicate whether there is the first time interval between the nth uplink transmission and the (n+1)th uplink transmission; N is a positive integer greater than 1; n is a positive integer, n is less than N.

[0482] In some embodiments, the first signaling includes a first transmission configuration, and the first transmission configuration is used by the first device to determine whether to set the first time interval between the multiple uplink transmissions.

[0483] It should be noted that the first signaling can include the first transmission configuration, and the first transmission configuration can be a transmission configuration of the multiple uplink transmissions of the first device. It can be understood that the first device can determine whether to set the first time interval between the multiple uplink transmissions according to the transmission configuration of the multiple uplink transmissions.

[0484] Notably, in some embodiments, the first signaling can only include the first transmission configuration. In this case, the first transmission configuration can not only indicate the transmission configuration of the multiple uplink transmissions of the first device, but also indicate the related configuration of the first time interval between the multiple uplink transmissions. In this way, the first transmission configuration of the multiple uplink transmissions is multiplexed to indicate whether the first time interval needs to be set between the multiple uplink transmissions; there is no need to carry additional related information indicating the first time interval in the first signaling.

[0485] For example, in the case where the first transmission configuration indicates that the number of uplink transmissions of the first device is 1, the first device can determine not to set the first time interval between the multiple uplink transmissions according to the first transmission configuration.

[0486] In some embodiments, the first signaling can include at least one of a first type of indication, a second type of indication, and a third type of indication in addition to the first transmission configuration.

[0487] In some embodiments, the first transmission configuration includes at least one of the following: a time domain position of the multiple uplink transmissions; a parameter of the uplink transmission; a third index used to indicate the number of uplink repetitions.

[0488] It should be noted that the multiple uplink transmissions of the first device can include at least one of the following: a first type of multiple uplink transmissions, which are multiple segmented transmissions for one data packet; and a second type of multiple uplink transmissions, which are uplink repetitions for one TB.

[0489] For the first type of multiple uplink transmission, the first sending configuration can comprise at least one of: time domain position of the multiple uplink transmission; parameter of the uplink transmission.

[0490] It can be understood that the second device can configure multiple time domain resources for the multiple uplink transmission of the first device; and carry information indicating the time domain position of the multiple uplink transmission by using the first sending configuration, so that the first device performs the multiple uplink transmission based on the configured multiple time domain resources of the multiple uplink transmission.

[0491] It is worth noting that in this case, the time domain position of the multiple uplink transmission can also be used to indicate whether the first time interval needs to be set between the multiple uplink transmissions. It can be understood that if the time domain positions of the multiple uplink transmissions are separated, it means that the first time interval needs to be set between the multiple uplink transmissions; if the time domain positions of the multiple uplink transmissions are connected, it means that the first time interval does not need to be set between the multiple uplink transmissions.

[0492] The second device can carry information indicating the parameter of the uplink transmission by using the first sending configuration, so that the first device performs segmentation processing on the data to be transmitted based on the parameter of the uplink transmission, to obtain at least one TB to be transmitted.

[0493] In some embodiments, in the case that the second device does not configure multiple time domain resources for the multiple uplink transmission of the first device, the first device can determine the number of the multiple uplink transmission based on the parameter of the uplink transmission in the first sending configuration; and determine whether the first time interval needs to be set between the multiple uplink transmissions according to the number of the multiple uplink transmission. In some embodiments, the parameter of the uplink transmission comprises at least one of: TB size of the uplink transmission; duration of the uplink transmission.

[0494] It can be understood that the second device indicates the TB size of the uplink transmission and / or the duration of the uplink transmission by using the first sending configuration, so that the first device performs segmentation on the data to be transmitted based on the above-mentioned parameters to obtain at least one TB to be transmitted. Thus, ambiguity about the transmission time length of the uplink transmission between the first device and the second device can be reduced.

[0495] For the second type of multiple uplink transmission, the first sending configuration can comprise: a third index, the third index being used to indicate the number of uplink repeated transmission.

[0496] It can be understood that the second device can configure the number of uplink repeated transmission of the first device by using the third index, so that the first device performs the multiple uplink transmission according to the configured number of uplink repeated transmission.

[0497] The number of uplink repeated transmissions can be pre-configured, and different numbers correspond to different indexes. Thus, according to the third index carried by the first sending configuration, the number corresponding to the third index is determined as the number of uplink repeated transmissions.

[0498] It is worth noting that the first device needs to determine whether to set the first time interval between multiple uplink transmissions only in the case that the number of uplink repeated transmissions indicated by the third index is greater than the third value. In the case that the number of uplink repeated transmissions indicated by the third index is equal to the third value, the first device does not need to set the first time interval. Here, the third value can be 1.

[0499] In some embodiments, the signaling type of the first signaling is used to indicate the number of uplink repeated transmissions.

[0500] It should be noted that the signaling type of the first signaling can implicitly indicate the number of uplink repeated transmissions. It can be understood that different types of first signaling correspond to different numbers of uplink repeated transmissions. Thus, the second device can indicate the number of uplink repeated transmissions of the first device by sending different types of first signaling to the first device; in this way, the third index does not need to be carried in the first signaling to indicate the specific number of uplink repeated transmissions.

[0501] In some embodiments, the frequency switching of the CW signal of the first device occurs at a third device, and the first signaling is used to indicate that the first time interval needs to be set between multiple uplink transmissions; or, the CW signal of the first device does not perform frequency switching, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions; or, the frequency switching of the CW signal of the first device occurs at a different third device, and the first signaling is used to indicate that the first time interval does not need to be set between multiple uplink transmissions.

[0502] Here, the third device is the sending device of the CW signal; the CW signal provides the energy of the uplink transmission of the first device. It should be noted that in the embodiments of the present disclosure, the second device sends the first signal (the first signal includes but is not limited to the CW signal) to the first device, so that the first device can backscatter based on the first signal to perform multiple uplink transmissions to the second device. In the case that the frequency switching of the CW signal occurs at one third device, since the frequency switching of the CW signal needs a certain processing time, in order to reduce the break between multiple uplink transmissions of the first device caused by the frequency switching, the second device can send the first signaling to the first device, which is used to indicate that the first time interval needs to be set between multiple uplink transmissions.

[0503] In a case where the frequency switching of the CW signal occurs at different third devices, since the frequency switching of the CW signal is caused by switching of multiple third devices, the first device cannot perceive the frequency switching of the CW signal in the time domain. Therefore, the second device can send, to the first device, first signaling for indicating that the first time interval does not need to be set between multiple uplink transmissions.

[0504] In a case where the CW signal does not perform frequency switching, the second device can send, to the first device, first signaling for indicating that the first time interval does not need to be set between multiple uplink transmissions.

[0505] It can be understood that the first device can send different first signaling to the first device according to different situations of the CW signal, so that the first device can determine whether to set the first time interval between multiple uplink transmissions according to different situations of the CW signal.

[0506] In some embodiments, the method further includes at least one of the following:

[0507] In a case where the first device has one third device and the CW signal sent by the third device has frequency switching, the first signaling is sent to the first device, and the first signaling is for indicating that the first time interval needs to be set between multiple uplink transmissions.

[0508] In a case where the first device has one third device and the CW signal sent by the third device does not have frequency switching, the first signaling is sent to the first device, and the first signaling is for indicating that the first time interval does not need to be set between multiple uplink transmissions.

[0509] In a case where the first device has multiple third devices and the CW signals sent by the multiple third devices have different frequencies, the first signaling is sent to the first device, and the first signaling is for indicating that the first time interval does not need to be set between multiple uplink transmissions.

[0510] Here, the third device is a transmitting device of the CW signal of the first device, that is, a CW N. It should be noted that the second device and the third device can be different nodes in the embodiments of the present disclosure.

[0511] It can be understood that the second device sends different first signaling to the first device according to different situations of the CW N of the first device, so that the first device determines whether to set the first time interval between multiple uplink transmissions.

[0512] In step S2302, the second device sends second signaling to the third device.

[0513] In some embodiments, the third device receives the second signaling sent by the second device.

[0514] In some embodiments, the second signaling is used for the third device to send the CW signal to the first device.

[0515] It should be noted that, in the case that the Reader of the first device and the CWN of the first device are not the same node, the second device sends signaling to the third device to instruct the third device to perform the frequency switching of the CW signal.

[0516] In some embodiments, the second signaling comprises a second sending configuration; the second sending configuration is the sending configuration of the CW signal.

[0517] It should be noted that the second device can explicitly inform the third device to send the CW signal to the first device through the second signaling, and explicitly indicate the related information of the frequency switching of the CW signal by using the second signaling, so as to reduce the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device.

[0518] In some embodiments, the second sending configuration comprises at least one of: a total sending duration of the CW signal; a starting sending time of the CW signal at the first frequency; an ending sending time of the CW signal at the first frequency; a sending duration of the CW signal at the first frequency; a sending period of the CW signal at the first frequency; a starting sending time of the CW signal at the second frequency; an ending sending time of the CW signal at the second frequency; a sending duration of the CW signal at the second frequency; and a sending period of the CW signal at the second frequency.

[0519] It can be understood that the second device actively sends the second sending configuration to the third device, so that the third device sends the CW signal to the first device according to the second sending configuration, so that the frequency switching of the CW signal occurs within the first time interval of the multiple uplink transmissions of the first device, thereby reducing the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device.

[0520] In some embodiments, the second device can determine the second sending configuration according to the first signaling.

[0521] It should be noted that the second device can determine the sending configuration information of the CW signal of the first device according to the related information of the first time interval between the multiple uplink transmissions of the first device indicated by the first signaling; so that the frequency switching of the CW signal of the first device does not affect the multiple uplink transmissions of the first device.

[0522] In some embodiments, sending the second signaling to the third device comprises:

[0523] The second device receives third signaling sent by the third device, and the third signaling comprises a third sending configuration, the third sending configuration being a sending configuration of the CW signal requested by the third device;

[0524] According to the third signaling, the second signaling is sent to the third device.

[0525] It should be noted that the third device can send third signaling to the second device to request the second device to allow the third device to send the CW signal according to the third sending configuration.

[0526] In some embodiments, the third signaling can be configuration request signaling.

[0527] In a case where the second device agrees to the third sending configuration requested by the third device, the second device determines the second sending configuration based on the third sending configuration.

[0528] It can be understood that the second device can determine the frequency switching of the CW signal requested by the third device according to the third sending configuration requested by the third device. If the frequency switching of the CW signal requested by the third device does not affect the multiple uplink transmissions of the first device, the second device can agree to the third sending configuration requested by the third device. At this time, the second sending configuration in the second signaling sent by the second device to the third device is the same as the third sending configuration.

[0529] In a case where the second device refuses the third sending configuration requested by the third device, the second device determines the second sending configuration based on the first signaling.

[0530] It can be understood that if the frequency switching of the CW signal requested by the third device affects the multiple uplink transmissions of the first device, the second device can refuse the third sending configuration requested by the third device. At this time, the second device can configure the second sending configuration of the CW signal for the third device according to the first signaling.

[0531] In some embodiments, sending the second signaling to the third device comprises at least one of:

[0532] Sending Radio Resource Control (RRC) signaling to the third device, wherein the RRC signaling comprises the second signaling;

[0533] Sending X2 signaling between base stations to the third device, wherein the X2 signaling comprises the second signaling.

[0534] It should be noted that the X2 interface is an interconnection interface between base stations. In a case where the second device and the third device are both base stations, the second device sends the X2 signaling between base stations to the third device to carry the second signaling by using the X2 signaling.

[0535] In a case where the second device and / or the third device is a terminal, the second device sends the RRC signaling to the third device to carry the second signaling by using the RRC signaling.

[0536] The second device can carry the second signaling in RRC signaling or X2 signaling, so that the second device sends the RRC signaling or the X2 signaling to the third device to send the second signaling to the third device, thereby reducing signaling overhead.

[0537] In some embodiments, when the second device and the third device are both base stations, the second device can send Xn signaling to the third device to carry the second signaling by using the Xn signaling.

[0538] In step S2303, the first device determines whether to set a first time interval between multiple uplink transmissions.

[0539] In some embodiments, the optional implementation of step S2303 can refer to the optional implementation of step S2102 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

[0540] In step S2304, the third device sends a CW signal to the first device.

[0541] In some embodiments, the first device receives the CW signal sent by the third device.

[0542] In some embodiments, the CW signal provides energy for the uplink transmission of the first device.

[0543] In some embodiments, the third device sends the CW signal to the first device, including: the third device sends the CW signal to the first device according to a second sending configuration.

[0544] It should be noted that the second sending configuration is the sending configuration of the CW signal of the first device. It can be understood that the second device configures the second sending configuration of the CW signal, so that the frequency switching of the CW signal sent according to the second sending configuration is within the first time interval between the multiple uplink transmissions of the first device, thereby reducing the impact of the frequency switching of the CW signal on the multiple uplink transmissions of the first device.

[0545] In the case where the second device sends the second signaling to the third device, the third device sends the CW signal to the first device according to the second sending configuration in the second signaling.

[0546] In step S2305, the first device performs multiple uplink transmissions.

[0547] In some embodiments, the optional implementation of step S2305 can refer to the optional implementation of step S2103 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

[0548] The information processing method related to the embodiments of the present disclosure can include at least one of steps S2301 to S2305. For example, step S2301 in combination with step S2303 can be implemented as an independent embodiment, steps S2301 in combination with steps S2303 and S2305 can be implemented as an independent embodiment, but are not limited thereto.

[0549] In some embodiments, steps S2302, S2304 and S2305 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0550] In some embodiments, steps S2302 and S2304 are optional, and one or more of these steps can be omitted or replaced in different embodiments. It can be understood that, in the case that the second device sends the CW signal to the first device, the first device can perform the multiple uplink transmissions based on the CW signal sent by the second device, without the second device sending the second signaling to the third device, and without the third device sending the CW signal to the first device.

[0620] FIG. 6 is an interaction diagram four illustrating a method of information processing according to an example embodiment.

[0624] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments.

[0625] The embodiments of the present disclosure can support CW signal frequency hopping while preventing a D2R transmission from being segmented at the physical layer by designing a mechanism for reserving a time interval (gap) between multiple transmissions of D2R (the multiple transmissions can be repeated transmissions or segmented transmissions of the same data packet).

[0626] In some embodiments, the first R2D signaling carries indication information indicating that the Device reserves a first time interval between multiple transmissions. In some embodiments, the indication information can include an indication bit, which indicates whether one or more Devices reserve the first time interval between their corresponding time slots or transmission opportunities.

[0627] It can be understood that the indication information corresponds to the first type of indication of the present disclosure.

[0628] In some embodiments, when the bit value of the indication bit is 1, it indicates that the first time interval needs to be reserved between multiple transmissions; when the bit value of the indication bit is 0, it indicates that the first time interval does not need to be reserved between multiple transmissions.

[0629] It should be noted that in the case where the Reader or CWN does not perform frequency switching of the CW signal, the Device does not reserve the first time interval between multiple transmissions. Alternatively, in the case where multiple Devices implement the switching of the CW signal from the first frequency f1 to the second frequency f2, the Device does not perceive the frequency switching of the CW signal, and therefore the Device does not reserve the first time interval between multiple transmissions.

[0630] In some embodiments, the length of the first time interval is preconfigured by the protocol.

[0631] In some embodiments, the multiple transmissions can be repeated transmissions of D2R, i.e., repeated N times for the same TB.

[0632] In some embodiments, the first R2D signaling can indicate the value of N.

[0633] In some embodiments, the first R2D signaling can include a third index, which indicates the number of repeated transmissions.

[0634] It can be understood that a list of the number of repeated transmissions is pre-configured, for example, 1, 2, 4, 8; wherein, the index #2 indicates that the number of repeated transmissions is 4 times.

[0635] It is worth noting that the first time interval is effective only when the number of repeated transmissions indicated by the third index is greater than 1.

[0636] In some embodiments, the signaling type of the first R2D signaling is used to determine the number of repeated transmissions.

[0637] It can be understood that the third index is not required to be carried in the first R2D signaling to indicate the specific number of repeated transmissions, and the number of repeated transmissions is associated with the signaling type of the first R2D signaling; that is, for a certain type of R2D signaling, the corresponding multiple uplink transmissions have corresponding numbers of repeated transmissions.

[0638] In some embodiments, the multiple transmissions can be multiple segmented transmissions, that is, for a data packet, M TBs are sent.

[0639] In some embodiments, in the case where the Reader allocates M time domain resources, the Reader can reserve the corresponding second time interval between the configured M time domains to ensure the interval between the multiple transmissions, so that the Device determines that the first time interval is required between the multiple transmissions according to the position separation of the M time domain resources, without additional indication.

[0640] In some embodiments, the Reader does not allocate corresponding time domain resources, and the first R2D signaling includes information indicating the TB size or duration length of one uplink transmission; the Device can perform segmented processing on the to-be-sent data according to the information.

[0641] This processing is to avoid ambiguity between the Reader and the Device about the transmission time length.

[0642] In some embodiments, the Device needs to carry information indicating whether there is still subsequent transmission in each transmitted TB.

[0643] In some embodiments, the second time interval is less than or equal to the first time interval.

[0644] It should be noted that the Reader or CWN can complete the frequency switching of the CW signal within the first time interval set by the Device; in this way, the Device cannot perceive the frequency switching of the CW signal. As shown in FIG. 7A, FIG. 7A is a schematic diagram of multiple transmissions of D2R according to an exemplary embodiment.

[0645] In some embodiments, the indication information can include a plurality of indication bits, indicating whether a first time interval is reserved between a plurality of transmissions when the one or more Devices transmit in their corresponding time slots or transmission occasions; and indicating a length of the first time interval.

[0646] It can be understood that the indication information corresponds to the second type of indication of the present disclosure.

[0647] In some embodiments, the length of the first time interval can be indicated by a first index indicating a specific candidate value.

[0648] For example, index #0 indicates that the length of the first time interval is 0; that is, indicating that no first time interval is reserved between a plurality of transmissions. Index #1 indicates that the length of the first time interval is 10μs. It can be understood that the list of candidate values of the first time interval can be pre-defined by the protocol.

[0649] In some embodiments, as shown in FIG. 7B, which is a schematic diagram II of a plurality of transmissions of a D2R according to an exemplary embodiment, for the plurality of transmissions, the first R2D signaling can include information indicating which transmissions need to reserve a first time interval and which transmissions do not need to reserve a first time interval.

[0650] Here, the information corresponds to the third type of indication in the embodiments of the present disclosure.

[0651] The position of the first time interval between the plurality of transmissions can be set according to the frequency hopping pattern of the CW signal.

[0652] In some embodiments, a second index can be used to indicate which transmissions need to reserve a first time interval.

[0653] It can be understood that different index values are configured in advance for different set positions of the first time interval between the plurality of transmissions; the Reader can use the second index for indication.

[0654] In some embodiments, the indication can be more dynamic in the form of a bit map.

[0655] In some embodiments, the CW signal is transmitted by the Reader.

[0656] It can be understood that the Reader and the CWN are the same node.

[0657] In some embodiments, the CW signal is transmitted by the CWN.

[0658] It can be understood that the Reader and the CWN are not the same node.

[0659] In some embodiments, the Reader instructs the CWN to perform the frequency switching of the CW signal when the Reader and the CWN are not the same node.

[0660] In some embodiments, the CWN can obtain the first time interval reservation status of the Device by obtaining the signaling content of the first R2D signaling, thereby implicitly obtaining the time point at which the CWN needs to perform the frequency switching and the time point at which the frequency switching needs to be completed.

[0661] It is worth noting that the two time points are respectively after the last uplink transmission of the Device and before the next downlink transmission.

[0662] In some embodiments, the Reader can send configuration information to the CWN, and the configuration information can indicate the transmission configuration of the CW signal.

[0663] It can be understood that the Reader can explicitly inform the CWN through the configuration information.

[0664] In some embodiments, the configuration information can include at least one of the following: the starting transmission time of the CW signal at the first frequency f1; the transmission duration of the CW signal at the first frequency f1; the total transmission duration of the CW signal; the starting transmission time of the CW signal at the second frequency f2; the transmission duration of the CW signal at the second frequency f2.

[0665] The CWN can determine the time of the frequency switching and complete the transmission of the CW signal at the second frequency according to the transmission configuration of the CW signal.

[0666] In some embodiments, the configuration information can be configured through an RRC message or an X2 signaling interface between base stations.

[0667] In some embodiments, the CWN can request the transmission configuration of the CW signal from the Reader, and the Reader can confirm the transmission configuration requested by the CWN; or the Reader can reject the transmission configuration requested by the CWN and configure other transmission configuration for the CWN.
