[0043] Embodiments of the present disclosure provide an information processing method, device, communication system and storage medium.

[0044] In a first aspect, embodiments of the present disclosure provide an information processing method, executed by a first device, comprising: in an inventory process, receiving uplink transmission and sending downlink transmission using different frequency domain resources, wherein the uplink transmission and the downlink transmission have overlap in time domain, and the uplink transmission and the downlink transmission are for different second devices.

[0045] In the above embodiment, in the inventory process, the uplink transmission and the downlink transmission can be received and sent using different frequency domain resources when there is time domain overlap between the uplink transmission and the downlink transmission, so that the use of time domain resources can be reduced, and thus the time delay of the entire inventory process can be reduced without affecting the uplink and downlink transmission.

[0046] In some embodiments in combination with the first aspect, the method further comprises: reducing a first time interval between two adjacent downlink transmissions to a second time interval, wherein the second time interval is greater than or equal to 0; and sending the two adjacent downlink transmissions based on the second time interval.

[0047] In the above embodiment, the time interval between the two adjacent downlink transmissions can be directly shortened, thereby reducing the time delay in the inventory process.

[0048] In some embodiments of the first aspect, in some embodiments, the uplink transmission and the downlink transmission overlap in the time domain, including at least one of: the Ith first signaling received by the first device overlaps in the time domain with the I+Jth second signaling sent by the first device, wherein the Ith first signaling is determined based on the Jth second signaling; the Kth third signaling sent by the first device overlaps in the time domain with the K+Lth first signaling received by the first device, wherein the Kth third signaling is determined based on the Kth first signaling; the Nth fourth signaling received by the first device overlaps in the time domain with the N+Mth third signaling sent by the first device, wherein the Nth fourth signaling is determined based on the Nth third signaling; the Oth fourth signaling received by the first device overlaps in the time domain with the O+Pth second signaling sent by the first device; wherein I, J, K, L, N, M, O and P are positive integers; the first signaling is a random number 16 RN 16 signaling or Msg1; and / or, the second signaling is a query Query signaling or a repeated query QueryRep signaling; and / or; the third signaling is a determination ACK signaling or Msg2; and / or, the fourth signaling is Msg3.

[0049] In the above embodiments, the Ith first signaling and the I+Jth second signaling, the Kth third signaling and the K+Lth first signaling, the Nth fourth signaling and the N+Mth third signaling, and / or the Oth fourth signaling and the O+Pth second signaling that overlap in the time domain can be transmitted using different frequency domain resources, so that different frequency domain resources can be used as much as possible for the uplink and downlink transmissions that overlap in the inventory process, and the time delay in the inventory process can be reduced as much as possible; and more application scenarios can be adapted.

[0050] In some embodiments of the first aspect, in some embodiments, the method comprises: after sending at least two second signalings, sending a third signaling, wherein the third signaling is sent by the first device after receiving the first signaling, and the first signaling is determined based on the second signaling.

[0051] In the above embodiments, the first device can send the third signaling after sending multiple second signalings, without waiting for the second device to return the first signaling after sending one second signaling, so that the time delay in the inventory process can also be reduced.

[0052] In some embodiments of the first aspect, in some embodiments, the method comprises at least one of: based on the first time domain length being less than the second time domain length, determining to set a third time interval between the first downlink transmission and the second downlink transmission, or based on the first time domain length being greater than or equal to the second time domain length, determining not to set a time interval between the first downlink transmission and the second downlink transmission; wherein the first time domain length and the second time domain length are respectively: the time domain length of the first downlink transmission and the first uplink transmission that have time domain overlap; the first downlink transmission and the second downlink transmission are adjacent.

[0053] In the above embodiment, when the first time domain length is less than the second time domain length, the time interval between the corresponding first downlink transmission and the second downlink transmission is set, so as to ensure that the first signaling or the fourth signaling sent by different second devices will not overlap in time domain, that is, the mutual interference between the first signaling and the fourth signaling between different second devices can be reduced. Alternatively, when the first time domain length is greater than or equal to the second time domain length, the interval between the first downlink transmission and the second downlink transmission does not need to be set, so as to reduce the time delay in the inventory process.

[0054] In some embodiments of the first aspect, the third time interval is greater than or equal to the difference between the second time domain length and the first time domain length; or the third time interval is greater than or equal to the difference between the second time domain length and the first time domain length and less than or equal to a predetermined value.

[0055] In the above embodiment, the interval (i.e., the third time interval) between the first downlink transmission and the second downlink transmission can be set to be greater than or equal to the difference between the second time domain length and the first time domain length, so as to reduce the situation that the first signaling or the fourth signaling sent by different second devices will not overlap in time domain; especially, if the third time interval is set to be equal to the difference between the second time domain length and the first time domain length, the situation that the first signaling or the fourth signaling sent by different second devices will not overlap in time domain can be reduced while the time delay in the inventory process is also reduced as much as possible. Moreover, if the third time interval is set to be less than or equal to a predetermined value, the time between the first downlink transmission and the second downlink transmission can be increased as little as possible, that is, the time delay in the entire inventory process can be reduced as much as possible.

[0056] In some embodiments of the first aspect, the first downlink transmission and the second downlink transmission are both QueryRep signaling; or the first downlink transmission and the second downlink transmission are respectively QueryRep signaling and third signaling; or the first downlink transmission and the second downlink transmission are both third signaling; or the first downlink transmission and the second downlink transmission are respectively third signaling and QueryRep signaling.

[0057] In the above embodiment, various cases of the first downlink transmission and the second downlink transmission are exemplified, so as to be applicable to more application scenarios.

[0058] In some embodiments of the first aspect, it is determined to set a fourth time interval between the Query signaling and the QueryRep signaling.

[0059] In some embodiments of the first aspect, in some embodiments, the two adjacent downlink transmissions are one of: an Xth third signaling and an X+Yth QueryRep signaling, X being a positive integer, Y being an integer greater than or equal to 0; an adjacent Query signaling and QueryRep signaling, wherein a time domain length of the QueryRep signaling is greater than or equal to a time domain length of the first signaling that overlaps with the QueryRep signaling; two adjacent QueryRep signalings, wherein a time domain length of at least one of the two adjacent QueryRep signalings is greater than or equal to a time domain length of the first signaling that overlaps with the QueryRep signaling in time domain; two adjacent third signalings, wherein a time domain length of at least one of the two adjacent third signalings is greater than or equal to a time domain length of the first signaling or fourth signaling that overlaps with the third signaling in time domain; an Xth QueryRep signaling and an X-Zth third signaling, wherein a time domain length of the Xth QueryRep signaling is greater than or equal to a time domain length of the first signaling or fourth signaling that overlaps with the Xth QueryRep signaling in time domain, and / or, a time domain length of the X-Zth third signaling is greater than or equal to a time domain length of the first signaling or fourth signaling that overlaps with the X-Zth third signaling in time domain; X being a positive integer greater than or equal to Z, Z being a positive integer.

[0065] In combination with some embodiments of the first aspect, in some embodiments, the first device has full duplex capability.

[0113] In some embodiments, Ambient IOT is a kind of IOT. Ambient-IoT devices have lower complexity and cost than NB-IoT devices, and have lower maintenance costs; the main feature of Ambient-IoT devices is that they have no battery, and are excited and powered by electromagnetic signals received by them; or have a battery with a small amount of electrical storage function, but the battery does not need to be manually charged, but can obtain battery energy from external energy, such as by obtaining external electromagnetic waves, thermal energy or kinetic energy, etc.

[0114] In some embodiments, Ambient IoT devices use backscatter communication technology, which is one of the key technologies for building green and energy-saving, low-cost, and flexible deployment of future IOT, and is an important means to realize "Internet of Everything".

[0115] Backscatter communication is a modulation and transmission technology with extremely low power consumption designed by using the principle of backscatter of radio frequency signals. Backscatter communication is that the radio frequency signal is received by the device, and the internal circuit of the device modulates the information to be transmitted on the basis of the incident electromagnetic wave through load impedance modulation and other ways, and then sends out the modulated electromagnetic wave carrying information. There can be various ways to modulate information, such as amplitude shift keying (ASK) modulation, frequency shift keying (FSK) modulation, or phase shift keying (PSK) modulation, etc.

[0116] For devices using backscatter communication, the device needs to have an energy source (such as a CW node) providing continuous wave (CW) to provide electromagnetic waves for reflection while transmitting data. CW is generally constant in amplitude. The CW node can be a separate node, or it can be a base station or an intermediate node (such as a UE, etc.) communicating with the device. The general working process is as follows: the network device sends downlink instructions to the device, and the device sends corresponding responses or performs corresponding operations to the network device after receiving the downlink instructions. However, the device needs to have a CW node to provide electromagnetic waves for reflection while transmitting data.

[0117] In some embodiments, different types of Ambient IoT devices and their working methods are different, and their power acquisition and storage capabilities are also different. Currently, the classification of Ambient IoT devices can be as follows:

[0118] Device 1: It has no energy storage capacity and no independent signal generation or amplification; for example, it uses a backscattering operation mode.

[0119] Device 2a: It has energy storage capabilities but does not generate independent signals; for example, it uses a backscattering operation. The stored energy can be used to amplify the reflected signal.

[0120] Device 2b: It has energy storage capabilities and independent signal generation; for example, it has an active radio frequency (RF) module that actively transmits signals.

[0121] Of the three types, device 2b has the strongest capability but also the highest terminal cost. Device 1 has the weakest capability but the lowest terminal cost. Furthermore, since device 1 or device 2a can only use backscattering operation and cannot actively transmit signals, they require other nodes to provide signal transmission (CW) as energy input. Device 2b can actively generate signals within its own circuitry using energy storage, thus eliminating the need for CW.

[0122] In some embodiments, such as FIG. 1B As shown, Ambient IoT comprises four types of links: Link 1 for transmitting downlink information, Link 2 for receiving uplink information, Link 3 for sending CW signals, and Link 4 for sending charging signals. The four nodes involved in these links can be a single node, or two, three, or four separate nodes. The Downlink Signal Node (DSN) transmits downlink information; the Uplink Receiver (UR) receives uplink information; the Continuous Wave Node (CWN) transmits continuous electromagnetic waves; and the Energy Source Node (ESN) provides the energy source.

[0123] like FIG. 1B The energy harvesting link (Link 4) in the system may be network-controlled. For example, the network can control the ESN to turn on or off to charge Ambient IoT devices, and this energy can come from electromagnetic waves or non-electromagnetic waves. In this case, the ESN can be considered to work better with network scheduling and other functions to ensure device charging while minimizing disruption to device communication. However, it is also possible that the ESN is not network-controlled, or that Ambient IoT devices flexibly harvest energy independently based on their capabilities and the energy sources in the actual environment, such as collecting electromagnetic or non-electromagnetic wave energy that is not controlled by the network, without a specific ESN node. In this case, Link 4 can be considered non-existent.

[0124] In some embodiments, the frequency of the electromagnetic wave reflected by the device can be exactly the same as the frequency of the CW, or there can be some offset value, the size of which is related to the software and / or hardware characteristics of the device. The offset value can be a fixed value, or if the device software and / or hardware supports, it can also support multiple fixed values, and it can also be a value that the device can dynamically adjust itself, or a value that the device dynamically sets according to the network indication.

[0125] In Ambient IoT, one possible way of frequency resource utilization is to divide the available spectrum into multiple sub-channels, each sub-channel occupying a fixed bandwidth, and the sub-channels are orthogonal in the frequency domain. The device can be instructed by the network to use one or more sub-channels to transmit data, or the device can select one or more sub-channels to transmit data through some algorithm.

[0126] For devices using backscatter communication, the operating bandwidth of their antennas is relatively wide, for example, tens of megahertz (Mhz). If the CWN transmits CW at multiple frequency points within the operating bandwidth of the device, the device will receive CW at multiple frequency points and backscatter all of them, that is, the device does not have the ability to reflect only the CW of the selected specific sub-channel.

[0127] In this sense, which uplink sub-channel the device can use to send uplink actually depends on the ability of the frequency of the CW and the offset value.

[0128] In some embodiments, inventory is an important application scenario in Ambient IoT. In the inventory business mode of a Radio Frequency Identification (RFID) system, for an RFID tag, after receiving a Query command, the tag sets a random value (counter) according to the Q value in the Query command, and the counter <= Q-1 (or counter <= 2^Q-1, in general, the upper limit of the counter is a value derived according to the Q value). If the counter = 0, the tag can start to send uplink information (for example, RN16 (such as 16-bit random number) used to temporarily represent the tag ID) by backscattering. If the counter is not 0, the tag does not send information and waits to receive a repeated Query (QueryRep) command. The tag reduces the counter value by 1 each time it receives a QueryRep command, until the counter value is reduced to 0, at which time the tag will switch to a reply state and backscatter uplink information. If the tag receives an Acknowledged (ACK) after sending the uplink information, it is confirmed that the tag has successfully accessed; otherwise, if an invalid ACK or an ACK and an error RN16 is received, or until a period of time (for example, T2) is reached without receiving a corresponding command, the tag considers that the access is unsuccessful. T2 is the time interval between the end of the tag sending signaling and the start of the reader sending signaling. In the Ambient IoT system, a similar inventory mechanism can also be used to handle the problem of inventorying multiple devices.

[0129] In some embodiments, the process in which the device reports its own information during the inventory process is also called a random access process. The random access of the device can be divided into two steps (2-step) random access and three steps (3-step) random access. In the 2-step random access mode, the device sends a message 1 (Msg1) (such as its own ID number, RN16), and the network device replies with a message 2 (ACK reply information) after receiving the Msg1. In the 3-step random access mode, the device sends a Msg1 (such as its own temporary ID number, RN16), and the network device replies with a Msg2 (ACK reply information) after receiving the Msg1. The device sends a Msg3 (such as its own ID and other uplink information, etc.) after receiving the Msg2.

[0130] As FIG. 1CAs shown, an example of 2-step random access is as follows: After a device sends uplink information, the network device immediately sends its corresponding ACK response information to the device. That is, after each QueryRep signaling, if the network device receives uplink information from the device, it will send an ACK response (denoted as the ACK response method for a single time-domain channel). For example, the network device can send Query / QueryRep signaling and ACK signaling to device 1, device 2, and device 3; device 1, device 2, and device 3 can send RN16 signaling to the network device, and the initial counter values ​​of device 1, device 2, and device 3 are 1, 2, and 3, respectively. In the absence of multiple device frequency division multiple access (FDMA), it can be done as follows: FIG. 1C As shown, if there are many devices, the entire inventory process will take a long time, i.e., the latency will be relatively long.

[0131] like FIG. 1D As shown, a method to reduce latency is provided, namely, using FDMA access on the uplink transmission resources of the devices, so that the uplink information of multiple devices is reported using different frequency domain resources. For example, the network device can send Query / QueryRep signaling and ACK signaling to devices 1, 2, 3, 4, and 5 respectively; devices 1, 2, 3, 4, and 5 can send ACK to the network device, and the initial counter value of devices 1 and 2 is 1, the initial counter value of device 3 is 2, and the counter value of devices 4, 5, and 6 is 3; the RN16 of devices 1 or 2 uses the same time domain resources but different frequency domain resources, device 3 sends RN16 alone, and devices 4, 5, and 6 use the same time domain resources but different frequency domain resources; accordingly, the network device sends an ACK to devices 1 and 2, an ACK to device 3, and an ACK to devices 4, 5, and 6.

[0132] In some embodiments, the first device can be one of the following: DSN, UR, CWN, and ESN; the second device can be any device that receives downlink information, such as a terminal, an Ambient IoT terminal, or an Ambient IoT device.

[0133] In some embodiments, the first device can be one of: a network device, a relay, an integrated access backhaul (IAB), a terminal, and a repeater; the second device can be a terminal. The network device can be, but is not limited to, an access network device (e.g., a base station). If the first device is a terminal, the first device is a first terminal, and the second device is a second terminal.

[0134] In some embodiments, the first device can be a reader or a scanner; the second device can be a tag, for example, the tag can be an RFID tag.

[0135] In some embodiments, the terminal can be a UE, and the UE can be a terminal.

[0136] As shown in FIG. 2A is an interaction diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG. 2A The present disclosure relates to an information processing method for an information processing system 100, the method comprising:

[0137] In step S2101, the first device determines a time interval between the downlink transmission and the uplink transmission.

[0138] In some embodiments, the first device sends the downlink transmission to at least one second device and / or receives the uplink transmission sent by at least one second device.

[0139] In some embodiments, the first device receiving the uplink transmission and the first device sending the downlink transmission are the same device, and the first device has full duplex capability. Here, the first device having full duplex capability means that the communication allows data to be transmitted in two directions at the same time, i.e., the first device is allowed to simultaneously send the downlink transmission and receive the uplink transmission. For example, the DSN and the UR are the same node.

[0140] In some embodiments, the first device receiving the uplink transmission and the first device sending the uplink transmission are different devices. For example, the DSN and the UR are different nodes.

[0141] In some embodiments, the first device is inventorying a plurality of second devices.

For example, the RN16 signaling can be referred to as Msg1, the ACK signaling can be referred to as Msg2, and the EPC signaling can be referred to as Msg3 signaling. For example, in the inventory process, if the feedback EPC signaling is invalid, the first device can also send a Negative Acknowledged (NAK) signaling.

Here, the start bit symbol indicates a start bit of the second signaling, the end bit symbol indicates an end bit of the second signaling, and the first indication is used to indicate a sequence number of the second signaling. For example, when the first device sends at least two consecutive second signaling, each of the second signaling can include at least one of: the start bit symbol, the end bit symbol, and the first indication. For another example, in other embodiments, the second signaling can not include the start bit symbol, the end bit symbol, and / or the first indication, etc.

[0147] For example, the second signaling further includes identification information of the second device.

[0148] For example, the third signaling includes at least one of: a start bit symbol, an end bit symbol, and a second indication. Here, the start bit symbol indicates a start bit of the third signaling, the end bit symbol indicates an end bit of the third signaling, and the second indication is used to indicate a sequence number of the third signaling. For example, when the first device sends at least two consecutive third signaling, each of the third signaling can include at least one of: the start bit symbol, the end bit symbol, and the second indication. For another example, in other embodiments, the third signaling can not include the start bit symbol, the end bit symbol, and / or the second indication, etc.

[0149] Exemplarily, the third signaling further comprises at least one of the following: identification information of the second device and response information.

[0153] Exemplarily, the first signaling, the second signaling, the third signaling and the fourth signaling can be respectively replaced by a first signal, a second signal, a third signal and a fourth signal; if the first signaling is replaced by the first signal, the first signal can comprise or carry RN16 signaling; if the second signaling is replaced by the second signal, the second signal can comprise Query or QueryRep signaling; if the third signaling is replaced by the third signal, the third signal can comprise ACK signaling; and if the fourth signaling is replaced by the fourth signal, the fourth signal can comprise sensitive data or Msg3.

[0154] Optionally, the first device can send the second signaling and / or the third signaling to at least one second device, and receive the first signaling and / or the fourth signaling sent by the at least one second device and the like.

[0155] In some embodiments, after the first device sends the second signaling at least twice, the first device sends the third signaling corresponding to the at least twice second signaling, and the third signaling is sent by the first device after receiving the first signaling returned based on the second signaling.

Exemplarily, as shown in FIG. 2, the first device can send four second signalings in succession, and then receive the first signalings returned by the devices 1 to 4, and then send the third signalings corresponding to the devices 1 to 4.

[0157] In some embodiments, the step S2101 comprises the step S2101A and / or the step S2101B.

[0158] In the step S2101A, the first device determines whether to set a time interval between the downlink transmission and the downlink transmission.

[0159] In some embodiments, the first device determines to set a third time interval between the first downlink transmission and the second downlink transmission.

[0160] In some embodiments, the first device determines to set the third time interval between the first downlink transmission and the second downlink transmission based on that the first time domain length is less than the second time domain length, wherein the first time domain length and the second time domain length are respectively: a time domain length of the first downlink transmission and the first uplink transmission with time domain overlap; and the first downlink transmission is adjacent to the second downlink transmission.

[0161] In some embodiments, the first device determines not to set a time interval between the first downlink transmission and the second downlink transmission based on that the first time domain length is greater than or equal to the second time domain length, wherein the first time domain length and the second time domain length are respectively: a time domain length of the first downlink transmission and the first uplink transmission with time domain overlap; and the first downlink transmission is adjacent to the second downlink transmission.

[0162] Optionally, the time domain overlap means that there is overlap in time domain; and the overlap in time domain can mean partial overlap or full overlap.

[0163] Optionally, the first downlink transmission and the second downlink transmission are both QueryRep signaling; and / or, the first downlink transmission and the second downlink transmission are respectively: QueryRep signaling and third signaling; and / or, the first downlink transmission and the second downlink transmission are both third signaling; and / or, the first downlink transmission and the second downlink transmission are respectively: third signaling and QueryRep signaling.

[0164] Optionally, the third time interval is greater than or equal to a difference between the second time domain length and the first time domain length; or, the third time interval is greater than or equal to the difference between the second time domain length and the first time domain length, and less than or equal to a predetermined value. Here, the predetermined value can be any value greater than or equal to the difference between the second time domain length and the first time domain length.

[0165] In some embodiments, the first device determines to set a fourth time interval between the third downlink transmission and the first downlink transmission.

[0166] In some embodiments, the first device determines not to set a fourth time interval between the third downlink transmission and the first downlink transmission. For example, it is determined to set the fourth time interval between Query signaling and QueryRep signaling.

[0167] Optionally, the third downlink transmission and the first downlink transmission are respectively: Query signaling and QueryRep signaling.

[0168] For example, as shown in FIG. 6, the first device 100 determines to set a fourth time interval between the third downlink transmission and the first downlink transmission. FIG. 2B-1As shown, the first device continuously sends four second signaling messages, including one Query signaling message and three QueryRep signaling messages; the second device sends a first signaling message to the first device, wherein the first second device (i.e., second device 1), the second second device (i.e., second device 2), the third second device (i.e., second device 3), and the fourth second device (i.e., second device 4) each send a first signaling message (i.e., RN16 signaling message or Msg1) to the first device; after receiving the first signaling messages sent by the four second devices, the first device sends a third signaling message (i.e., ACK signaling message or Msg2) to the four second devices respectively.

[0169] exist FIG. 2B-1 In this context, the Query signaling and the first QueryRep signaling can be the third downlink transmission and the first downlink transmission, respectively. Therefore, a fourth time interval, such as T1, can be set between the Query signaling and the first QueryRep signaling.

[0170] exist FIG. 2B-1 In this context, the first QueryRep signaling and the second QueryRep signaling can be the first downlink transmission and the second downlink transmission, respectively, or the second QueryRep signaling and the third QueryRep signaling can be the first downlink transmission and the second downlink transmission, respectively. If the first QueryRep signaling overlaps with the first RN16 signaling or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length of the first QueryRep signaling (i.e., the first time domain length) is less than the time domain length of the first RN16 signaling or Msg1 (i.e., the second time domain length), then a third time interval, such as T2, can be set between the first QueryRep signaling and the second QueryRep signaling. Similarly, a third time interval, such as T2, can also be set between the second QueryRep signaling and the third QueryRep signaling.

[0171] exist FIG. 2B-1 In this context, the third QueryRep signaling and the first third signaling (i.e., ACK signaling or Msg2) can be the first downlink transmission and the second downlink transmission, respectively. The third QueryRep signaling overlaps with the third RN16 signaling or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length of the third QueryRep signaling (i.e., the first time domain length) is less than the time domain length of the third RN16 signaling or Msg1 (i.e., the second time domain length). Therefore, a third time interval, such as T2, can be set between the third QueryRep signaling and the first third signaling.

[0172] exist FIG. 2B-1In the embodiment, the first third signaling (i.e., ACK signaling or Msg2) and the second third signaling (i.e., ACK signaling or Msg2) can be the first downlink transmission and the second downlink transmission, respectively, or the second third signaling and the third third signaling can be the first downlink transmission and the second downlink transmission, respectively, or the third third signaling and the fourth third signaling can be the first downlink transmission and the second downlink transmission, respectively. When the first ACK signaling or Msg2 and the fourth RN16 signaling or Msg1 (i.e., the first uplink transmission) overlap in the time domain, and the time domain length (i.e., the first time domain length) of the first ACK signaling or Msg2 is less than the time domain length (i.e., the second time domain length) of the fourth RN16 signaling or Msg1, a third time interval, such as T2, can be set between the first ACK signaling or Msg2 and the second ACK signaling or Msg2. Similarly, a third time interval can also be set between the second ACK signaling or Msg2 and the third ACK signaling or Msg2, and / or a third time interval can be set between the third ACK signaling or Msg2 and the fourth ACK signaling or Msg2.

[0173] For example, as shown in FIG. 6, the fourth third signaling (i.e., ACK signaling or Msg2) and the fifth second signaling (i.e., the fourth QueryRep signaling) can be the first downlink transmission and the second downlink transmission, respectively, on the basis of the continuous transmission of the plurality of second signaling. FIG. 2B-2 FIG. 2B-1 For example, as shown in FIG. 6, the fourth third signaling (i.e., ACK signaling or Msg2) and the fifth second signaling (i.e., the fourth QueryRep signaling) can be the first downlink transmission and the second downlink transmission, respectively, on the basis of the continuous transmission of the plurality of second signaling.

[0174] In the embodiment, the continuous transmission of the four first signaling (i.e., RN16 signaling or Msg1) is only an example. FIG. 2B-1 In the embodiment, the continuous transmission of the four first signaling (i.e., RN16 signaling or Msg1) and the continuous transmission of the four fourth signaling (Msg3) are only examples. FIG. 2B-2 In other embodiments, the four first signaling and the four fourth signaling can be discontinuously transmitted, and / or the fourth first signaling and the first fourth signaling can also be discontinuously transmitted. The embodiments of the present disclosure do not limit whether the adjacent two uplink transmissions of the second device are continuous.

[0175] For example, as shown in FIG. 6, the fourth third signaling (i.e., ACK signaling or Msg2) and the fifth second signaling (i.e., the fourth QueryRep signaling) can be the first downlink transmission and the second downlink transmission, respectively, on the basis of the continuous transmission of the plurality of second signaling. FIG. 2C ​As shown, the first device continuously sends three second signaling messages, including one Query signaling message and two QueryRep signaling messages; the second device sends a first signaling message to the first device, wherein the first second device (i.e., device 1), the second second device (i.e., device 2), and the third second device (i.e., device 3) each send a first signaling message (i.e., RN16 signaling message or Msg1) to the first device; after receiving the first signaling messages sent by the three second devices, the first device sends a third signaling message (i.e., ACK signaling message or Msg2) to the three second devices respectively.

[0176] like FIG. 2C As shown, the Query signaling and the first QueryRep signaling can be the third downlink transmission and the first downlink transmission, respectively, so there is no need to set a time interval between the Query signaling and the first QueryRep signaling.

[0177] like FIG. 2C As shown, the first QueryRep signaling and the second QueryRep signaling can be the first downlink transmission and the second downlink transmission, respectively. The first QueryRep signaling overlaps with the first RN16 signaling or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length of the first QueryRep signaling (i.e., the first time domain length) is greater than or equal to the time domain length of the first RN16 signaling or Msg1 (i.e., the second time domain length). Therefore, no time interval needs to be set between the first QueryRep signaling and the second QueryRep signaling.

[0178] In one optional embodiment, the first device determines whether to set a third time interval between the first downlink transmission and the second downlink transmission based on the relationship between the first time domain length and the second time domain length. Optionally, determining whether to set a third time interval between the first downlink transmission and the second downlink transmission based on the relationship between the first time domain length and the second time domain length includes: determining that a third time interval should be set between the first downlink transmission and the second downlink transmission based on the first time domain length being less than the second time domain length; or determining that a third time interval should not be set between the first downlink transmission and the second downlink transmission based on the first time domain length being greater than or equal to the second time domain length.

[0179] Step S2101B: The first device reduces the time interval between at least two downlink transmissions.

[0180] In some embodiments, the first device reduces the time interval between at least two downlink transmissions during the inventory process.

[0181] In some embodiments, the first device reduces the time interval between two adjacent downlink transmissions.

[0182] In some embodiments, the first device narrows a first time interval between two adjacent downlink transmissions to a second time interval, where the second time interval is greater than or equal to 0. Here, the first time interval is greater than the second transmission interval.

[0183] Optionally, the two adjacent downlink transmissions are: an Xth third signaling and an X+Yth QueryRep signaling, where X is a positive integer and Y is an integer greater than 0. For example, the two adjacent downlink transmissions are: a previous third signaling and a next second signaling (e.g., QueryRep signaling).

[0184] Optionally, the two adjacent downlink transmissions are: an adjacent Query signaling and QueryRep signaling, where a time domain length of the QueryRep signaling is greater than or equal to a time domain length of a first signaling that overlaps with the QueryRep signaling.

[0185] Optionally, the two adjacent downlink transmissions are: two adjacent QueryRep signalings, where a time domain length of at least one of the two adjacent QueryRep signalings is greater than or equal to a time domain length of a first signaling that overlaps with the QueryRep signaling in time domain.

[0186] Optionally, the two adjacent downlink transmissions are: two adjacent third signalings, where a time domain length of any one of the two adjacent third signalings is greater than or equal to a time domain length of a first signaling or a fourth signaling that overlaps with the third signaling in time domain. Here, the first signaling or the fourth signaling that overlaps with the third signaling in time domain can refer to: an uplink transmission that overlaps with the third signaling in time domain.

[0187] Optionally, the two adjacent downlink transmissions are: an Xth QueryRep signaling and an X-Zth third signaling, where a time domain length of the Xth QueryRep signaling is greater than or equal to a time domain length of a first signaling or a fourth signaling that overlaps with the Xth QueryRep signaling in time domain, and / or, a time domain length of the X-Zth third signaling is greater than or equal to a time domain length of a first signaling or a fourth signaling that overlaps with the X-Zth third signaling in time domain; X is a positive integer greater than or equal to Z, and Z is a positive integer. Optionally, the two adjacent downlink transmissions are: a next second signaling (e.g., QueryRep signaling) and a previous third signaling; or, the two adjacent downlink transmissions are: an Xth second signaling and an X-Zth third signaling. Here, the first signaling or the fourth signaling that overlaps with the Xth QueryRep signaling in time domain can refer to: an uplink transmission that overlaps with the Xth QueryRep signaling in time domain; the first signaling or the fourth signaling that overlaps with the X-Zth third signaling in time domain can refer to: an uplink transmission that overlaps with the X-Zth third signaling in time domain.

[0188] Optionally, when the time interval between two adjacent downlink transmissions is 0, the two downlink transmissions can be sent continuously (without interruption).

[0189] Optionally, in two adjacent downlink transmissions, each downlink transmission uses the same frequency domain resources as the corresponding uplink transmission, or in two adjacent downlink transmissions, each downlink transmission uses different frequency domain resources as the corresponding uplink transmission.

[0190] For example, such as FIG. 2D As shown, after the first device sends the first second signaling (i.e., Query signaling), it receives the first first signaling (i.e., RN16 signaling or Msg1) sent by the first second device (i.e., device 1), and then sends the first third signaling (i.e., ACK signaling or Msg2); after the first device sends the second second signaling (i.e., QueryRep signaling), it receives the second first signaling (i.e., RN16 signaling or Msg1) sent by the second second device (i.e., device 2), and then sends the second third signaling (i.e., ACK signaling or Msg2); and so on, the first device continues to send the third second signaling (i.e., QueryRep signaling), and so on. FIG. 2D In this context, downlink transmissions from network device to second device (e.g., second or third signaling) and uplink transmissions from second device to network device (e.g., first signaling) are on the same or different frequency domain resources; for example, Msg2 and Msg2 signaling and QueryRep signaling are transmitted continuously without intervals; Msg2 signaling and QueryRep signaling should be able to be decoded independently.

[0191] exist FIG. 2D In this context, two adjacent downlink transmissions can be: the first third signaling and the second second signaling (e.g., the first QueryRep signaling), or two adjacent downlink transmissions can be: the second third signaling and the third second signaling (e.g., the second QueryRep signaling). Therefore, the interval between the first third signaling and the second second signaling (e.g., the first QueryRep signaling) can be reduced to make the time interval between the first third signaling and the second second signaling zero. Similarly, the interval between the second third signaling and the third second signaling (e.g., the second QueryRep signaling) can be reduced to make the time interval between the second third signaling and the third second signaling zero. Of course, in other embodiments, the time interval between the first third signaling and the second second signaling can be reduced, without having to set the time interval between the first third signaling and the second second signaling to 0; and / or, the time interval between the second third signaling and the third second signaling can be reduced, without having to set the time interval between the second third signaling and the third second signaling to 0.

[0192] For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-1 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-1 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-2 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0.

[0193] For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-1 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-1 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-2 For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0.

[0194] For example, in the case that the two adjacent downlink transmissions are Query signaling and the 1st QueryRep signaling, and the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the first signaling (i.e., RN16 signaling or Msg1) that has a time domain overlap with the 1st QueryRep signaling, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in the case that the time interval between the Query signaling and the 1st QueryRep signaling is T1, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0. FIG. 2E-1In this context, two adjacent downlink transmissions can be: the first third signaling (i.e., ACK or Msg2) and two third signalings, or the second and third third signalings, or the third and fourth third signalings. If the time domain length of the first third signaling is greater than or equal to that of an uplink transmission that sometimes overlaps with the first third signaling (e.g., the fourth first signaling), and / or the time domain length of the second third signaling is greater than or equal to that of an uplink transmission that sometimes overlaps with the third third signaling (e.g., the first fourth signaling), then the time interval between the first and second third signalings can be reduced. Similarly, the time interval between the second and third third signalings can be reduced, and / or the time interval between the third and fourth third signalings can be reduced. Optionally, by reducing the time interval between the first and second third signaling messages, the first and second third signaling messages can be sent continuously (uninterruptedly). For example, in FIG. 2E-1 In the sequence, the time interval between the first and second third signaling messages is T2, the time interval between the second and third third signaling messages is T2, and the time interval between the third and fourth third signaling messages is T2; FIG. 2E-2 In the middle, the time interval between the first and second third signaling is reduced to 0, the time interval between the second and third third signaling is reduced to 0, and the time interval between the third and fourth third signaling is reduced to 0.

[0195] exist FIG. 2E-1 In this context, two adjacent downlink transmissions can be: the fourth second signaling (i.e., the third QueryRep signaling) and the first third signaling (i.e., the ACK signaling or Msg2); if the time domain length of the third QueryRep signaling is greater than or equal to the time domain length of the third second signaling that sometimes overlaps with the third QueryRep signaling, and / or, the time domain length of the first third signaling is greater than or equal to the time domain length of the fourth second signaling that sometimes overlaps with the first third signaling, then the time interval between the third QueryRep signaling and the first third signaling can be reduced. For example, in... FIG. 2E-1 In the context of the QueryRep signaling, the time interval between the first QueryRep signaling and the first third signaling is T2; FIG. 2E-2 In this case, the time interval between the third QueryRep signaling and the first third signaling is reduced to 0, at which point the third QueryRep signaling and the first third signaling can be sent continuously (without interruption).

[0196] For example, such as FIG. 2DAs shown, two adjacent downlink transmissions can be: the first third signaling and the second second signaling (e.g., the first QueryRep signaling), where the second second signaling and the corresponding second first signaling use the same frequency domain resources, etc. FIG. 2D In this process, the downlink transmission from the first device to the second device and the uplink transmission from the second device to the first device can both use the same frequency domain resources.

[0197] For example, such as FIG. 2E-1 As shown, two adjacent downlink transmissions can be: a Query signaling and a first QueryRep signaling, and / or, two adjacent downlink transmissions can be: a first QueryRep signaling and a second QueryRep signaling, etc.; then the first QueryRep signaling uses different frequency domain resources than the corresponding first first signaling, and / or, the second QueryRep signaling uses different frequency domain resources than the corresponding second first signaling, and / or the third QueryRep signaling uses different frequency domain resources than the corresponding third first signaling. FIG. 2E-1 In this process, the downlink transmission from the first device to the second device and the uplink transmission from the second device to the first device can both use different frequency domain resources.

[0204] In step S2102A, the first device uses different frequency domain resources to receive uplink transmissions and send downlink transmissions.

[0205] In some embodiments, during the inventory process, the first device uses different frequency domain resources to receive uplink transmissions and send downlink transmissions.

[0315] Step S5101, the first device receives the uplink transmission sent by one second device and sends the downlink transmission to another second device using different frequency domain resources in the inventory process, wherein the uplink transmission overlaps with the downlink transmission in time domain.

[0319] In step S5103, the first device sends the two adjacent downlink transmissions to the second device based on the second time interval.

[0320] The optional implementation in step S5103 of the method in the embodiment of the disclosure can refer to the optional implementation in step S2102B of the method in the embodiment of the disclosure, FIG. 2C The optional implementation in step S3102 of the method in the embodiment of the disclosure, FIG. 2C The optional implementation in step S4101 of the method in the embodiment of the disclosure, and FIG. 2G , FIG. 2C , FIG. 2D , FIG. 2D Other associated parts in the embodiments involved in the above are not described here again.

[0321] The embodiment of the disclosure provides an information processing method, which comprises: in an inventory process, a first device sends a downlink transmission to a second device; a second device sends an uplink transmission to another first device; where when the uplink transmission and the downlink transmission overlap in the time domain, the uplink transmission and the downlink transmission use different frequency domain resources.

[0322] In some embodiments, the above method can include the method described in the above embodiments of the information processing system side, the first device side, and / or the second device side, which is not described here again.

[0323] The embodiment of the disclosure relates to an information processing method, which can include one of the following: embodiment one, a method for reducing latency based on two-step (2-step) random access; embodiment two, a method for reducing latency based on three-step (3-step) random access; and embodiment three, a method for reducing time by reducing a time interval between downlink transmissions.

[0324] Example 1: A method for reducing latency based on two-step random access.

[0325] In some embodiments, the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR use different frequency domain resources, and the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR overlap in the time domain. For example... FIG. 6A or FIG. 6A In scenarios such as these, the Query signaling or QueryRep signaling overlaps in the time domain with the RN16 signaling (or Msg1) sent by the second device triggered by the previous Query signaling or QueryRep signaling; for example... FIG. 6B or FIG. 6B The first QueryRep signaling message overlaps with the first RN16 signaling message (or Msg1) in the time domain. For example, the RN16 (or Msg1) sent by the second device overlaps with the ACK signaling message (or Msg2) sent by the network device to other second devices in the time domain. FIG. 7A The fourth RN16 (or Msg1) overlaps with the first ACK (or Msg2) in the time domain, or FIG. 7A The third RN16 (or Msg1) overlaps with the first ACK (or Msg2) in the time domain.

[0326] Optionally, the network device can be the first device in the above embodiments. The network device can be a DSN or a UR; either a DSN or a UR can be the first device in the above embodiments.

[0327] Optionally, when the second device is performing uplink transmission, it does not need to listen for downlink transmission. For a second device performing uplink transmission using backscattering, since the second device needs to modulate the CW before reflection during uplink transmission, the frequency resources of the CW should generally be different from the frequency resources of the downlink information transmitted by the DSN. The second device may include a filter component, and the second device may not receive other downlink information transmitted by the DSN when receiving the CW.

[0328] Optionally, the DSN and UR can be different nodes, or the DSN and UR can be the same node; if the DSN and UE are the same node, the node has full-duplex capability.

[0329] Optionally, the network device may send Q consecutive Query signaling or QueryRep signaling before sending an ACK signaling (or Msg2) in response to the received RN16 signaling (or Msg1) from the second device; for example, FIG. 7A Q is 4, or as FIG. 7B Q is of the power of 3. Of course, in other embodiments, Q can be any positive integer.

[0330] Optionally, such as FIG. 7B As shown, if the time domain length of the QueryRep signaling is less than the time domain length of the RN16 signaling (or Msg1) of the second device, a time interval needs to be set between the QueryRep signaling messages; the interval length T2 is greater than or equal to the difference between the time domain length of the RN16 signaling (or Msg1) of the second device and the time domain length of the QueryRep signaling. Alternatively, as... ​ As shown, if the time domain length of the QueryRep signaling is greater than or equal to the time domain length of the RN16 signaling (or Msg1) of the second device, then no interval needs to be set between QueryRep signaling messages. Of course, in cases such as... ​ In such scenarios, setting an interval is also possible, but it will increase latency. Here, the interval duration T2 is the third time interval in the previous embodiment.

[0331] Optionally, such as ​ As shown, an interval can be set between the Query signaling and the QueryRep signaling, and the duration of this interval can be T1; or, as... ​ As shown, no time interval is set between the Query signaling and the QueryRep signaling. For example, the interval duration T1 can be equal to or greater than 0. Here, the interval duration T1 can be the fourth time interval in the previous embodiment.

[0332] Optionally, the Query signaling and the QueryRep signaling are continuous in the time domain, and the Query signaling and the QueryRep signaling are different signaling systems. For example, the Query signaling and the QueryRep signaling have identifiable start and / or end bits; or, the Query signaling and the QueryRep signaling may carry sequence numbers, with the Query signaling carrying a sequence number to mark the order of the Query signaling and the QueryRep signaling carrying a sequence number to mark the order of the QueryRep signaling. Here, the sequence numbers carried by the Query signaling and the QueryRep signaling may be included in the second signaling in the previous embodiment, which includes a first indication.

[0333] Example 2: A method for reducing latency based on three-step random access.

[0334] In some embodiments, the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR use different frequency domain resources, and the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR may overlap in the time domain. ​In the scenario, the Query signaling or the QueryRep signaling overlaps in time domain with the RN16 signaling (or Msg1) sent by the second device triggered by the previous Query signaling or the QueryRep signaling; and / or, the RN16 signaling (or Msg1) sent by the second device overlaps in time domain with the ACK signaling (or Msg2) sent by the network device to other second devices; and / or, the ACK signaling (or Msg2) sent by the network device to a certain second device overlaps in time domain with the Msg3 of another second device.

[0335] Optionally, the network device can be the first device in the above embodiments. The network device can be a DSN or a UR; both the DSN and the UR can be the first device in the above embodiments.

[0336] Optionally, when the second device is performing uplink transmission, it does not need to perform downlink transmission listening. For the second device performing uplink transmission by backscattering, since the second device needs to modulate the CW before reflection when performing uplink transmission, the frequency resource of the CW should generally be different from the frequency resource of the downlink information sent by the DSN. The second device can include a filter component, and the second device can not receive other downlink information sent by the DSN when receiving the CW.

[0337] Optionally, the DSN and the UR can be different nodes, or the DSN and the UR are the same node; if the DSN and the UR are the same node, the node has full-duplex capability.

[0338] Optionally, the network device can continuously send Q times of Query signaling or QueryRep signaling, and then send the ACK signaling (or Msg2) in response to the received RN16 signaling (or Msg1) of the second device; for example, as shown in ​ Q is 2. Of course, in other embodiments, Q can be any positive integer, for example, Q is 3 or 4, etc.

[0339] Optionally, after receiving the ACK signaling (or Msg2) corresponding to the second device, the second device will send Msg3.

[0340] Optionally, as shown in ​ If the time domain length of the QueryRep signaling or the Msg2 signaling is less than the time domain length of the signaling (for example, Msg1 or Msg3 of the second device) that overlaps in time domain, a time interval needs to be set between the QueryRep signaling or between the QueryRep signaling and the ACK signaling (or Msg2) or between the ACK signaling (or Msg2); the interval duration T2 is greater than or equal to the difference between the time domain length of the Msg1 of the second device and the time domain length of the QueryRep signaling. Or, as shown in ​As shown, if the time domain length of the QueryRep signaling is greater than or equal to the time domain length of the Msg1 of the second device, no interval is needed to be set between the QueryRep signaling or between the QueryRep signaling and the ACK signaling (or Msg2). Of course, in the scenario as shown in ​ , the interval can also be set, but the latency will be increased. Here, the interval duration T2 is the third time interval in the previous embodiment.

[0341] Optionally, as shown in ​ , an interval can be set between the Query signaling and the QueryRep signaling, and the interval duration can be T1; or, as shown in ​ , no time interval is set between the Query signaling and the QueryRep signaling. Exemplarily, the interval duration T1 can be equal to 0 or greater than 0. Here, the interval duration T1 can be the fourth time interval in the previous embodiment.

[0342] Optionally, the Query signaling and the QueryRep signaling are continuous in the time domain, and the Query signaling and the QueryRep signaling are different signaling. For example, the Query signaling and the QueryRep signaling have identifiable start bit symbols and / or end bit symbols; or, the Query signaling and the QueryRep signaling can carry sequence numbers, the Query signaling carries a sequence number for marking the sequence number of the Query signaling, and the QueryRep signaling carries a sequence number for marking the sequence number of the QueryRep signaling. Here, the Query signaling and the QueryRep signaling carrying the sequence numbers can be the first indication included in the second signaling in the previous embodiment.

[0343] Embodiment three, a method for reducing the time interval between the base station and the downlink transmission to reduce the time.

[0344] In some embodiments, in the scenario as shown in ​ , the time interval between the ACK signaling (or Msg2) and the next QueryRep signaling can be reduced so that the ACK signaling (or Msg2) and the QueryRep signaling can be continuously sent.

[0345] Optionally, the downlink transmission of the DSN to the second device and the uplink transmission of the second device to the UR use the same or different frequency domain resources. For example, in the scenario as shown in ​ , the downlink transmission of the DSN to the second device and the uplink transmission of the second device to the UR use the same frequency resources.

[0346] Optionally, the ACK signaling (or Msg2) and the QueryRep signaling are continuously sent, and the ACK signaling (or Msg2) and the QueryRep signaling each have a clear start bit and / or end bit. Here, the ACK signaling (or Msg2) and the QueryRep signaling can be independently decoded.

[0347] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.

[0348] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device including units or modules for implementing each step performed by a terminal in any of the above methods.
