[0044] The embodiments of the present disclosure provide an information processing method, device, communication system and storage medium.

[0045] In a first aspect, the 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.

[0046] 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.

[0047] In combination with some embodiments of the first aspect, in some embodiments, 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.

[0048] In the above embodiment, the time interval between the two adjacent downlink transmissions can be directly shortened, so that the time delay in the inventory process can be reduced.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the uplink transmission and the downlink transmission have overlap in time domain, including at least one of the following: the Ith first signaling received by the first device and the I+Jth second signaling sent by the first device have overlap in time domain, wherein the Ith first signaling is determined based on the Jth second signaling; the Kth third signaling sent by the first device and the K+Lth first signaling received by the first device have overlap in time domain, wherein the Kth third signaling is determined based on the Kth first signaling; the Nth fourth signaling received by the first device and the N+Mth third signaling sent by the first device have overlap in time domain, wherein the Nth fourth signaling is determined based on the Nth third signaling; the Oth fourth signaling received by the first device and the O+Pth second signaling sent by the first device have overlap in time domain; 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.

[0050] In the above embodiments, the first I signaling and the second I+J signaling, the third K signaling and the first K+L signaling, the fourth N signaling and the third N+M signaling, and / or the fourth O signaling and the second O+P signaling that have overlaps in time domain can be transmitted using different frequency domain resources, so that the uplink and downlink transmissions that have overlaps in time domain in the inventory process can use different frequency domain resources as much as possible, and the time delay in the inventory process can be reduced as much as possible; and more application scenarios can be adapted.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the method comprises: after transmitting the at least two second signaling, transmitting third signaling, wherein the third signaling is transmitted by the first device after receiving the first signaling, and the first signaling is determined based on the second signaling.

[0052] In the above embodiments, the first device can transmit the third signaling after transmitting the multiple second signaling, without waiting for the second device to return the first signaling after transmitting one second signaling, so that the time delay in the inventory process can also be reduced.

[0053] In combination with some embodiments of the first aspect, in some embodiments, the method comprises at least one of the following: 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: time domain lengths of the first downlink transmission and the first uplink transmission that have time domain overlaps; the first downlink transmission and the second downlink transmission are adjacent.

[0054] In the above embodiments, 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 that the first signaling or the fourth signaling transmitted by different second devices will not have time domain overlaps, i.e., the mutual interference between the first signaling and the fourth signaling between different second devices can be reduced. Or, 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 that the time delay in the inventory process can be reduced.

[0055] In combination with some embodiments of the first aspect, in some embodiments, 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 is less than or equal to a predetermined value.

[0056] In the above embodiments, the interval (i.e., the third time interval) between the first downlink transmission and the second downlink transmission can be greater than or equal to the difference between the second time domain length and the first time domain length, which can reduce the case that the first signaling or the fourth signaling sent by different second devices do 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 time delay in the inventory process can be reduced while reducing the case that the first signaling or the fourth signaling sent by different second devices do not overlap in time domain. 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 reduced, i.e., the time delay in the entire inventory process can be reduced.

[0057] In some embodiments of the first aspect, in some embodiments, 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.

[0058] In the above embodiments, various cases of the first downlink transmission and the second downlink transmission are exemplified, so that more application scenarios can be applied.

[0059] In some embodiments of the first aspect, in some embodiments, the fourth time interval is set between the Query signaling and the QueryRep signaling.

[0060] 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.

[0061] In the above embodiments, various cases between the two adjacent downlink transmissions are exemplified, which can shorten the time interval between the two adjacent downlink transmissions as much as possible in the entire inventory process, so as to reduce the latency in the entire inventory process as much as possible; and more application scenarios can also be applied.

[0062] In some embodiments of the first aspect, in some embodiments, each of the two adjacent downlink transmissions uses the same frequency domain resource as the corresponding uplink transmission, or each of the two adjacent downlink transmissions uses different frequency domain resources as the corresponding uplink transmission.

[0063] In the above embodiments, if each of the two adjacent downlink transmissions uses different frequency domain resources as the corresponding uplink transmission, the latency in the inventory process can be further reduced.

[0064] In some embodiments of the first aspect, in some embodiments, when at least two QueryRep signalings are consecutively sent, each QueryRep signaling includes at least one of: a start bit symbol, an end bit symbol, and a first indication indicating a sequence number of the QueryRep signaling; and / or when at least two third signalings are consecutively sent, each third signaling includes at least one of: a start bit symbol, an end bit symbol, and a second indication indicating a sequence number of the third signaling.

[0065] In the above embodiments, when the QueryRep signaling and the third signaling set the start bit symbol, the end bit symbol and / or the indication information indicating the sequence number of the signaling, the at least one second device can correctly receive the downlink transmission belonging to itself, and the success rate of decoding the downlink transmission is improved, etc.

[0066] In combination with some embodiments of the first aspect, in some embodiments, the first device has full duplex capability.

[0114] 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.

[0115] 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".

[0116] Backscatter communication is a modulation and transmission technology with extremely low power consumption designed based on the principle of radio frequency signal backscatter. Backscatter communication is that the radio frequency signal is received by a 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 methods, and then sends out the modulated electromagnetic wave carrying information. There are many ways to modulate information, such as amplitude shift keying (ASK) modulation, frequency shift keying (FSK) modulation, or phase shift keying (PSK) modulation, etc.

[0117] 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 intermediate node (such as 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.

[0118] 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:

[0119] Device 1: No energy storage capability, no independent signal generation or amplification; for example, using backscattering working mode.

[0120] Device 2a: With energy storage capability, no independent signal generation; for example, using backscattering working mode. The stored energy can be used for amplification of the reflected signal.

[0121] Device 2b: With energy storage capability, with independent signal generation; for example, there is an active Radio Frequency (RF) module that actively transmits signals.

[0122] Among the above three types, the capability of device 2b is the strongest, and the terminal cost is also the highest. The capability of device 1 is the weakest, and the terminal cost is also the lowest. In addition, device 1 or device 2a can only use the backscattering working mode and cannot actively transmit signals, so it needs other nodes to provide CW as energy input. Device 2b can actively generate signals in the device circuit using stored energy, so it does not need CW.

[0123] In some embodiments, as shown in FIG. 1B, in Ambient IoT, a total of 4 links are included, which are respectively used for transmitting downlink information (Link 1), receiving uplink information (Link 2), transmitting CW (Link 3), and transmitting energy charging signals (Link 4). The four nodes involved in the four links can be the same node, or two, three or four separate nodes. The Downlink Signal Node (DSN) is the node that transmits the downlink information; the Uplink receiver (UR) is the node that receives the uplink information; the Continuous wave Node (CWN) is the node that transmits continuous electromagnetic waves; and the Energy Source Node (ESN) is the node that provides the energy source.

[0124] The energy collection link (Link 4) in FIG. 1B can be controlled by the network, for example, the network can control the ESN to turn on or off the charging of the Ambient IoT device, and the energy can come from electromagnetic waves or non-electromagnetic waves. In this case, it can be considered that the ESN can better cooperate with the network scheduling function, so as to ensure that the device is charged while minimizing the impact on the communication of the device. However, it is also possible that the ESN is not controlled by the network, or in other words, the Ambient IoT device flexibly collects energy according to the device capability and the energy source in the actual environment, for example, collects electromagnetic or non-electromagnetic energy that is not controlled by the network, without a specific ESN node. In this case, it can be considered that Link 4 does not exist.

[0125] 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 also 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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 a 16-bit random number) temporarily representing 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 are 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.

[0130] In some embodiments, the process in which the device reports its own information during the inventory process is also called a random access process. Random access of the device can be divided into two-step (2-step) random access and three-step (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 receives the Msg1 and responds with a Msg2 (ACK response information). In the 3-step random access mode, the device sends a Msg1 (such as its own temporary ID number, RN16), and the network device receives the Msg1 and responds with a Msg2 (ACK response information), and the device receives the Msg2 and sends a Msg3 (such as its own ID and other uplink information, etc.).

[0131] As shown in FIG. 1C, one example of 2-step random access is as follows: after the device sends the uplink information, the network device immediately sends the ACK response information corresponding to the device to the device, that is, the network device performs ACK feedback (denoted as the ACK feedback mode of a single time domain channel) after sending the QueryRep signaling each time if the uplink information sent by the device is received. For example, the network device can send Query / QueryRep signaling and ACK signaling to the device 1, the device 2 and the device 3; the device 1, the device 2 and the device 3 can send RN16 signaling to the network device, and the initial counter values of the device 1, the device 2 and the device 3 are 1, 2 and 3 respectively. In the case of no frequency division multiple access (FDMA) of multiple devices, as shown in FIG. 1C, if the number of devices is relatively large, the time taken by the entire inventory process will be relatively long, that is, the delay is relatively long.

[0132] As shown in FIG. 1D, a way to reduce the delay is provided, that is, the FDMA access mode can be used on the uplink transmission resource of the device, so that the uplink information of multiple devices is reported by using different frequency domain resources. For example, the network device can send Query / QueryRep signaling and ACK signaling to the device 1, the device 2, the device 3, the device 4 and the device 5 respectively; the device 1, the device 2, the device 3, the device 4 and the device 5 can send ACK to the network device, and the initial counter values of the device 1 and the device 2 are 1, the initial counter value of the device 3 is 2, and the counter values of the device 4, the device 5 and the device 6 are 3; the RN16 of the device 1 or the device 2 uses the same time domain resource but different frequency domain resources, the device 3 sends the RN16 alone, and the device 4, the device 5 and the device 6 use the same time domain resource but different frequency domain resources; accordingly, the network device sends one ACK to the device 1 and the device 2, sends one ACK to the device 3, and sends one ACK to the device 4, the device 5 and the device 6.

[0133] In some embodiments, the first device can be one of the following: DSN, UR, CWN and ESN; the second device can be any device receiving downlink information, for example, a terminal or an Ambient IoT terminal or an Ambient IoT device, etc.

[0134] 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.

[0135] 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.

[0136] In some embodiments, the terminal can be a UE, and the UE can be a terminal.

[0137] 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 embodiment of the present disclosure relates to an information processing method for an information processing system 100, and the method comprises:

[0138] In step S2101, the first device determines a time interval between the downlink transmission and the downlink transmission.

[0139] 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.

[0140] 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 both 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.

[0141] 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.

[0142] 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.

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.

[0148] For example, the second signaling further includes identification information of the second device.

[0149] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0158] In some embodiments, the step S2101 comprises a step S2101A and / or a step S2101B.

[0159] In the step S2101A, the first device determines whether to set a time interval between the downlink transmission and the downlink transmission.

[0160] In some embodiments, the first device determines to set a third time interval between the first downlink transmission and the second downlink transmission.

[0161] 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.

[0162] 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.

[0163] 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.

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.

[0166] In some embodiments, the first device determines to set a fourth time interval between the third downlink transmission and the first downlink transmission.

[0167] 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.

[0168] Optionally, the third downlink transmission and the first downlink transmission are respectively: Query signaling and QueryRep signaling.

[0169] As shown in FIG. 2B-1, the first device sends 4 second signals successively, and the 4 second signals include 1 Query signal and 3 QueryRep signals; the second device sends the first signals to the first device, wherein the first second device (i.e., the second device 1), the second second device (i.e., the second device 2), the third second device (i.e., the second device 3) and the fourth second device (i.e., the second device 4) send the first signals (i.e., RN16 signals or Msg1) to the first device respectively; after the first device receives the first signals sent by the 4 second devices, the first device sends the third signals (i.e., ACK signals or Msg2) to the 4 second devices respectively.

[0170] In FIG. 2B-1, the Query signal and the first QueryRep signal can be the third downlink transmission and the first downlink transmission respectively, and a fourth time interval, such as T1, can be set between the Query signal and the first QueryRep signal.

[0171] In FIG. 2B-1, the first QueryRep signal and the second QueryRep signal can be the first downlink transmission and the second downlink transmission respectively, or the second QueryRep signal and the third QueryRep signal can be the first downlink transmission and the second downlink transmission respectively; the first QueryRep signal overlaps with the first RN16 signal or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length (i.e., the first time domain length) of the first QueryRep signal is less than the time domain length (i.e., the second time domain length) of the first RN16 signal or Msg1, so a third time interval, such as T2, can be set between the first QueryRep signal and the second QueryRep signal; similarly, a third time interval, such as T2, can also be set between the second QueryRep signal and the third QueryRep signal.

[0172] In FIG. 2B-1, the third QueryRep signal and the first third signal (i.e., the ACK signal or Msg2) can be the first downlink transmission and the second downlink transmission respectively; the third QueryRep signal overlaps with the third RN16 signal or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length (i.e., the first time domain length) of the third QueryRep signal is less than the time domain length (i.e., the second time domain length) of the third RN16 signal or Msg1, so a third time interval, such as T2, can be set between the third QueryRep signal and the first third signal.

[0173] In FIG. 2B-1, the 1st third signaling (i.e., ACK signaling or Msg2) and the 2nd third signaling (i.e., ACK signaling or Msg2) can be the first downlink transmission and the second downlink transmission, respectively, or the 2nd third signaling and the 3rd third signaling can be the first downlink transmission and the second downlink transmission, respectively, or the 3rd third signaling and the 4th third signaling can be the first downlink transmission and the second downlink transmission, respectively; the 1st ACK signaling or Msg2 and the 4th 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 1st ACK signaling or Msg2 is less than the time domain length (i.e., the second time domain length) of the 4th RN16 signaling or Msg1, a third time interval, such as T2, can be set between the 1st ACK signaling or Msg2 and the 2nd ACK signaling or Msg2. Similarly, a third time interval can also be set between the 2nd ACK signaling or Msg2 and the 3rd ACK signaling or Msg2, and / or a third time interval can be set between the 3rd ACK signaling or Msg2 and the 4th ACK signaling or Msg2.

[0174] For example, as shown in FIG. 2B-2, based on FIG. 2B-1, a plurality of second signaling are continuously transmitted, the 4th third signaling (i.e., ACK signaling or Msg2) and the 5th second signaling (i.e., the 4th QueryRep signaling) can be the first downlink transmission and the second downlink transmission, respectively. At this time, if the inventory is for a three-step random access process, the 4th third signaling (i.e., ACK signaling or Msg2) can overlap with the 3rd Msg3 (i.e., the first uplink transmission) in the time domain, and if the time domain length (i.e., the first time domain length) of the 4th ACK signaling or Msg2 is less than the time domain length (i.e., the second time domain length) of the 3rd Msg3, a third time interval, such as T2, can be set between the 4th ACK signaling or Msg2 and the 4th QueryRep signaling.

[0175] In FIG. 2B-1, the continuous transmission of the 4 first signaling (i.e., RN16 signaling or Msg1) is only an example; in FIG. 2B-2, the continuous transmission of the 4 first signaling (i.e., RN16 signaling or Msg1) and the continuous transmission of the 4 fourth signaling (Msg3) are only examples; in other embodiments, the 4 first signaling and the 4 fourth signaling can be discontinuously transmitted, and / or the 4th first signaling and the 1st 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.

[0176] As shown in FIG. 2C, the first device successively sends 3 second signals, including 1 Query signal and 2 QueryRep signals; the second device sends the first signal to the first device, wherein the 1st second device (i.e., device 1), the 2nd second device (i.e., device 2), and the 3rd second device (i.e., device 3) each sends the first signal (i.e., RN16 signal or Msg1) to the first device; after the first device receives the first signals sent by the 3 second devices, the first device sends the third signal (i.e., ACK signal or Msg2) to the 3 second devices respectively.

[0177] As shown in FIG. 2C, the Query signal and the 1st QueryRep signal can be the third downlink transmission and the first downlink transmission respectively, and no time interval can be set between the Query signal and the 1st QueryRep signal.

[0178] As shown in FIG. 2C, the 1st QueryRep signal and the 2nd QueryRep signal can be the first downlink transmission and the second downlink transmission respectively; the 1st QueryRep signal overlaps with the 1st RN16 signal or Msg1 (i.e., the first uplink transmission) in the time domain, and the time domain length of the 1st QueryRep signal (i.e., the first time domain length) is greater than or equal to the time domain length of the 1st RN16 signal or Msg1 (i.e., the second time domain length), and no time interval can be set between the 1st QueryRep signal and the 2nd QueryRep signal.

[0179] In an optional embodiment, the first device determines whether to set the third time interval between the first downlink transmission and the second downlink transmission based on the size relationship between the first time domain length and the second time length. Optionally, determining whether to set the third time interval between the first downlink transmission and the second downlink transmission based on the size relationship between the first time domain length and the second time length includes: determining 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; or determining not 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 greater than or equal to the second time domain length.

[0180] Step S2101B: The first device reduces the time interval between at least two downlink transmissions.

[0181] In some embodiments, the first device reduces the time interval between at least two downlink transmissions in the inventory process.

[0182] In some embodiments, the first device reduces the time interval between adjacent two downlink transmissions.

[0183] 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.

[0184] 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).

[0185] 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.

[0186] 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 in time domain with the QueryRep signaling.

[0187] 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 in time domain with the third signaling. Here, the first signaling or the fourth signaling that overlaps in time domain with the third signaling can refer to an uplink transmission that overlaps in time domain with the third signaling.

[0188] 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 in time domain with the Xth QueryRep signaling, 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 in time domain with the X-Zth third signaling; 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 in time domain with the Xth QueryRep signaling can refer to an uplink transmission that overlaps in time domain with the Xth QueryRep signaling; the first signaling or the fourth signaling that overlaps in time domain with the X-Zth third signaling can refer to an uplink transmission that overlaps in time domain with the X-Zth third signaling.

[0189] Optionally, the time interval between the two adjacent downlink transmissions is 0, i.e., the two adjacent downlink transmissions can be transmitted continuously (without interruption).

[0190] Optionally, each of the two adjacent downlink transmissions uses the same frequency domain resource as the corresponding uplink transmission, or each of the two adjacent downlink transmissions uses different frequency domain resources as the corresponding uplink transmission.

[0191] For example, as shown in FIG. 2D, after the first device transmits the first second signaling (i.e., Query signaling), it receives the first first signaling (i.e., RN16 signaling or Msg1) transmitted by the first second device (i.e., device 1), and then transmits the first third signaling (i.e., ACK signaling or Msg2); after the first device transmits the second second signaling (i.e., QueryRep signaling), it receives the second first signaling (i.e., RN16 signaling or Msg1) transmitted by the second second device (i.e., device 2), and then transmits the second third signaling (i.e., ACK signaling or Msg2); and so on. In FIG. 2D, the downlink transmission (e.g., second signaling or third signaling) from the network device to the second device and the uplink transmission (e.g., first signaling) from the second device to the network device are on the same or different frequency domain resources; for example, the Msg2 and the QueryRep signaling can be transmitted continuously without interval, and the Msg2 signaling and the QueryRep signaling can be independently decoded.

[0192] In FIG. 2D, the two adjacent downlink transmissions can be the first third signaling and the second second signaling (e.g., the first QueryRep signaling), or the two adjacent downlink transmissions can be the second third signaling and the third second signaling (e.g., the second QueryRep signaling); then the interval between the first third signaling and the second second signaling (e.g., the first QueryRep signaling) can be reduced so that the time interval between the first third signaling and the second second signaling is 0; similarly, the interval between the second third signaling and the third second signaling (e.g., the second QueryRep signaling) can be reduced so that the time interval between the second third signaling and the third second signaling is 0. Of course, in other embodiments, only the time interval between the first third signaling and the second second signaling needs to be reduced, and it is not necessary to make the time interval between the first third signaling and the second second signaling 0; and / or, only the time interval between the second third signaling and the third second signaling needs to be reduced, and it is not necessary to make the time interval between the second third signaling and the third second signaling 0.

[0193] For example, as shown in FIG. 2E-1, the two adjacent downlink transmissions can be: 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, so that the time interval between the Query signaling and the 1st QueryRep signaling can be reduced. For example, in FIG. 2E-1, the time interval between the Query signaling and the 1st QueryRep signaling is T1; in FIG. 2E-2, the time interval between the Query signaling and the 1st QueryRep signaling can be reduced to 0, and the Query signaling and the 1st QueryRep signaling can be transmitted continuously.

[0194] In FIG. 2E-1, the two adjacent downlink transmissions can be: the 1st QueryRep signaling and the 2nd QueryRep signaling, or the two adjacent downlink transmissions can be: the 2nd QueryRep signaling and the 3rd QueryRep signaling; the time domain length of the 1st QueryRep signaling is greater than or equal to the time domain length of the 1st first signaling (i.e., RN16 signaling or Msg1) that has an overlap with the 1st QueryRep signaling, and / or the time domain length of the 2nd QueryRep signaling is greater than or equal to the time domain length of the 2nd first signaling (i.e., RN16 signaling or Msg1) that has an overlap with the 2nd QueryRep signaling, so that the time interval between the 1st QueryRep signaling and the 2nd QueryRep signaling can be reduced; similarly, the time interval between the 2nd QueryRep signaling and the 3rd QueryRep signaling can be reduced. For example, in FIG. 2E-1, the time interval between the 1st QueryRep signaling and the 2nd QueryRep signaling is T2, and the time interval between the 2nd QueryRep signaling and the 3rd QueryRep signaling is T2; in FIG. 2E-2, the third time interval between the 1st QueryRep signaling and the 2nd QueryRep signaling can be reduced to 0, and the third time interval between the 2nd QueryRep signaling and the 3rd QueryRep signaling can be reduced to 0.

[0195] In FIG. 2E-1, the two adjacent downlink transmissions can be: the 1st third signaling (i.e., ACK or Msg2) and the 2nd third signaling, or the two adjacent downlink transmissions can be: the 2nd third signaling and the 3rd third signaling, or the two adjacent downlink transmissions can be: the 3rd third signaling and the 4th third signaling; the time domain length of the 1st third signaling is greater than or equal to the time domain length of the uplink transmission (e.g., the 4th first signaling) that has time domain overlap with the 1st third signaling, and / or the time domain length of the 2nd third signaling is greater than or equal to the time domain length of the uplink transmission (e.g., the 1st fourth signaling) that has time domain overlap with the 3rd third signaling, then the time interval between the 1st third signaling and the 2nd third signaling can be reduced; similarly, the time interval between the 2nd third signaling and the 3rd third signaling can be reduced, and / or the time interval between the 3rd third signaling and the 4th third signaling can be reduced. Optionally, if the time interval between the 1st third signaling and the 2nd third signaling is reduced, the 1st third signaling and the 2nd third signaling can be transmitted continuously (without interruption). For example, in FIG. 2E-1, the time interval between the 1st third signaling and the 2nd third signaling is T2, the time interval between the 2nd third signaling and the 3rd third signaling is T2, and the time interval between the 3rd third signaling and the 4th third signaling is T2; in FIG. 2E-2, the time interval between the 1st third signaling and the 2nd third signaling is reduced to 0, the time interval between the 2nd third signaling and the 3rd third signaling is reduced to 0, and the time interval between the 3rd third signaling and the 4th third signaling is reduced to 0.

[0196] In FIG. 2E-1, the two adjacent downlink transmissions can be: the 4th second signaling (i.e., the 3rd QueryRep signaling) and the 1st third signaling (i.e., ACK signaling or Msg2); the time domain length of the 3rd QueryRep signaling is greater than or equal to the time domain length of the 3rd second signaling that has time domain overlap with the 3rd QueryRep signaling, and / or the time domain length of the 1st third signaling is greater than or equal to the time domain length of the 4th second signaling that has time domain overlap with the 1st third signaling, then the time interval between the 3rd QueryRep signaling and the 1st third signaling can be reduced. For example, in FIG. 2E-1, the time interval between the 3rd QueryRep signaling and the 1st third signaling is T2; in FIG. 2E-2, the time interval between the 3rd QueryRep signaling and the 1st third signaling is reduced to 0, and at this time the 3rd QueryRep signaling and the 1st third signaling can be transmitted continuously (without interruption).

[0197] For example, as shown in FIG. 2D, the two adjacent downlink transmissions can be: the 1st third signaling and the 2nd second signaling (e.g., the 1st QueryRep signaling), the 2nd second signaling and the corresponding 2nd first signaling use the same frequency domain resource, etc. In FIG. 2D, the downlink transmission sent by the first device to the second device and the uplink transmission sent by the second device to the first device can use the same frequency domain resource.

[0198] For example, as shown in FIG. 2E-1, the two adjacent downlink transmissions can be: the Query signaling and the 1st QueryRep signaling, and / or, the two adjacent downlink transmissions can be: the 1st QueryRep signaling and the 2nd QueryRep signaling, etc.; the 1st QueryRep signaling and the corresponding 1st first signaling use different frequency domain resources, and / or, the 2nd QueryRep signaling and the corresponding 2nd first signaling use different frequency domain resources, and / or, the 3rd QueryRep signaling and the corresponding 3rd first signaling use different frequency domain resources. In FIG. 2E-1, the downlink transmission sent by the first device to the second device and the uplink transmission sent by the second device to the first device can use different frequency domain resources.

[0199] In step S2102, the first device determines the first operation.

[0200] Optionally, the first operation can include: receiving the uplink transmission and sending the downlink transmission using different frequency domain resources in the inventory process.

[0201] Optionally, the first operation can include: sending at least two downlink transmissions with reduced time intervals.

[0202] Optionally, the first operation can include: the above-mentioned step S2101B, and sending at least two downlink transmissions with reduced time intervals.

[0203] Optionally, the name of the first operation is not limited, which is, for example, a latency reduction operation or a related operation of reducing latency, etc.

[0204] In some embodiments, step S2102 can include step S2102A and step S2102B.

[0205] In step S2102A, the first device receives the uplink transmission and sends the downlink transmission using different frequency domain resources.

[0206] In some embodiments, the first device receives the uplink transmission and sends the downlink transmission using different frequency domain resources in the inventory process.

[0207] In some embodiments, the uplink transmission sent by the first device and the downlink transmission received by the first device overlap in time domain; and the uplink transmission and the downlink transmission are for different second devices.

[0208] Optionally, the downlink transmission sent by the first device to one second device and the uplink transmission received by the first device from another second device use different frequency domain resources, and the downlink transmission sent by the first device to one second device and the uplink transmission received by the first device from another second device overlap in time domain.

[0209] Optionally, the overlap in time domain can be partial overlap or full overlap. For example, the downlink transmission of the first device for one second device and the uplink transmission for another second device partially or fully overlap in time domain.

[0210] Optionally, the uplink transmission and the downlink transmission overlap in time domain, including that the Ith first signaling received by the first device and the I+Jth second signaling sent by the first device overlap in time domain, wherein the Ith first signaling is determined based on the Jth second signaling; and wherein I and J are positive integers. Exemplarily, J is 1; of course, in other embodiments, J can be any positive integer.

Exemplarily, M is 1; of course, in other embodiments, M can be any positive integer.

[0213] Optionally, the uplink transmission and the downlink transmission overlap in time domain, including that the Oth fourth signaling received by the first device and the O+Pth second signaling sent by the first device overlap in time domain; and wherein O and P are positive integers. Exemplarily, P is 1; of course, in other embodiments, P can be any positive integer.

[0214] For example, as shown in FIG. 2F, the first device receives the first first signaling and transmits the first+first=2 second signaling (i.e., the first QueryRep signaling) overlapping in the time domain, and uses different frequency domain resources to receive the first first signaling and transmit the second second signaling. In other embodiments, if the device 1 transmits the first first signaling, which is transmitted when the first device transmits the fourth second signaling; the first first signaling and the fourth second signaling overlap in the time domain, and different time domain resources are used to receive the first first signaling and transmit the fourth second signaling. In FIG. 2F, there is a time interval T1 between the first second signaling and the second second signaling, and a time interval T2 between the second second signaling and the third second signaling.

[0215] For example, as shown in FIG. 2F, the first device receives the first first signaling and transmits the first+first=2 second signaling (i.e., the first QueryRep signaling) overlapping in the time domain, and uses different frequency domain resources to receive the first first signaling and transmit the second second signaling. In other embodiments, if the device 1 transmits the first first signaling, which is transmitted when the first device transmits the fourth second signaling; the first first signaling and the fourth second signaling overlap in the time domain, and different time domain resources are used to receive the first first signaling and transmit the fourth second signaling. In FIG. 2F, there is a time interval T1 between the first second signaling and the second second signaling, and a time interval T2 between the second second signaling and the third second signaling.

[0216] In FIG. 2F, the four first signaling (i.e., RN16 signaling or Msg1) is continuously transmitted, which is only an example; in other embodiments, the four first signaling can be discontinuously transmitted; the embodiments of the present disclosure do not limit whether the adjacent two uplink transmissions of the second device are continuous.

[0217] For example, as shown in FIG. 2G, the first device receives the first fourth signaling and transmits the first+first=2 third signaling overlapping in the time domain, and uses different frequency domain resources to receive the first fourth signaling and transmit the second third signaling. In FIG. 2G, there is a time interval T1 between the first second signaling and the second second signaling, a time interval T2 between the second second signaling and the first third signaling, and a time interval T2 between the first third signaling and the second third signaling.

[0218] For example, as shown in FIG. 2H, the first device receives the second fourth signaling and transmits the second+first=3 second signaling overlapping in the time domain, and uses different frequency domain resources to receive the second third signaling and transmit the third second signaling.

Before the first device transmits the two adjacent downlink transmissions based on the second time interval, the first device further includes: reducing the first time interval between the two adjacent downlink transmissions to the second time interval, wherein the second time interval is greater than or equal to 0.

[0224] For example, the first device reduces the time interval between the two adjacent downlink transmissions to 0, and then consecutively transmits the two downlink transmissions.

[0225] In FIG. 2D, the first device can transmit the 2nd third signaling and the 3rd second signaling (e.g., the 2nd QueryRep signaling) with reduced time interval, and / or transmit the 1st third signaling and the 2nd second signaling with reduced time interval, and / or transmit the 2nd third signaling and the 3rd second signaling with reduced time interval. Optionally, if the time interval between the 2nd third signaling and the 3rd second signaling is reduced to 0,

[0322] The embodiments of the present disclosure provide an information processing method, comprising: in an inventory process, a first device sends downlink transmission to a second device; a second device sends uplink transmission to another first device; wherein 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.

[0323] 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 will not be repeated here.

[0324] Embodiments of the present disclosure relate to information processing methods, which can include one of the following: Embodiment One, a method for reducing latency based on a two-step (2-step) random access; Embodiment Two, a method for reducing latency based on a three-step (3-step) random access; and Embodiment Three, a method for reducing latency by reducing the time interval between downlink transmissions.

[0325] Embodiment One, a method for reducing latency based on a two-step random access.

[0326] 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, in the scenario of FIG. 2F or FIG. 2C, the Query signaling or the 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, the first QueryRep signaling overlaps in the time domain with the first RN16 signaling (or Msg1) in FIG. 2F or FIG. 2C. The RN16 signaling (or Msg1) sent by the second device overlaps in the time domain with the ACK signaling (or Msg2) sent by the network device to other second devices; for example, the fourth RN16 signaling (or Msg1) overlaps in the time domain with the first ACK signaling (or Msg2) in FIG. 2F, or the third RN16 signaling (or Msg1) overlaps in the time domain with the first ACK signaling (or Msg2) in FIG. 2C.

[0327] Optionally, the network device can be the first device in the above embodiments. The network device can be the DSN or the UR; both the DSN and the UR can be the first device in the above embodiments.

[0328] Optionally, when the second device is performing uplink transmission, it does not need to perform listening of downlink transmission. 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.

[0329] Optionally, the DSN and the UR can be different nodes, or the DSN and the UR can be the same node; if the DSN and the UR are the same node, the node has full-duplex capability.

[0330] Optionally, the network device can send the response information ACK signaling (or Msg2) of the received RN16 signaling (or Msg1) of the second device after sending the Q times of Query signaling or QueryRep signaling in succession; for example, as shown in FIG. 2F, Q is 4 times, or as shown in FIG. 2C, Q is 3 times. Of course, in other embodiments, Q can be any positive integer.

[0331] Optionally, as shown in FIG. 2F, 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; the interval duration 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. Or, as shown in FIG. 2C, 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, no interval needs to be set between the QueryRep signaling. Of course, in the scenario as shown in FIG. 2C, the interval can also be set, but the time delay will be increased. Here, the interval duration T2 is the third time interval in the previous embodiment.

[0332] Optionally, as shown in FIG. 2F, an interval can be set between the Query signaling and the QueryRep signaling, and the interval duration can be T1; or, as shown in FIG. 2C, 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.

[0333] Optionally, the Query signaling and the QueryRep signaling are continuous in 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 include the first indication in the second signaling in the previous embodiment.

[0334] Embodiment two, a method for reducing time delay based on three-step random access.

[0335] 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 can have overlap in time domain. In the scenario of FIG. 2G, the Query signaling or the QueryRep signaling has overlap 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 has overlap 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 has overlap in time domain with the Msg3 of another second device.

[0336] Optionally, the network device can be the first device in the above embodiments. The network device can be the DSN or the UR; both the DSN and the UR can be the first device in the above embodiments.

[0337] Optionally, when the second device is performing uplink transmission, it does not need to perform listening of downlink transmission. 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.

[0338] 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.

[0339] Optionally, the network device can successively 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 FIG. 2G, Q is 2. Of course, in other embodiments, Q can be any positive integer, for example, Q can be 3 or 4, etc.

[0340] Optionally, after receiving the ACK signaling (or Msg2) corresponding to the second device, the second device will send the Msg3.

[0341] Optionally, as shown in FIG. 2G, if the time domain length of the QueryRep signaling or the Msg2 signaling is less than the time domain length of the signaling (e.g., Msg1, Msg3 of the second device) that has a time domain overlap with the QueryRep signaling, a time interval needs to be set between the QueryRep signaling or between the QueryRep signaling and the ACK signaling (or Msg2) signaling 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. Alternatively, as shown in FIG. 2C, 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 needs 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 FIG. 2C, an interval can also be set, but this will increase the latency. Here, the interval duration T2 is the third time interval in the previous embodiments.

[0342] Optionally, as shown in FIG. 2G, an interval can be set between the Query signaling and the QueryRep signaling, and the interval duration can be T1; alternatively, as shown in FIG. 2C, 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 embodiments.

[0343] 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; alternatively, 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 embodiments.

[0344] Embodiment three, a method for reducing the time interval between the base and the downlink transmission to reduce the time.

[0345] In some embodiments, as shown in the scenario of FIG. 2D, the time interval between the ACK signaling (or Msg2) and the next QueryRep signaling can be deleted so that the ACK signaling (or Msg2) and the QueryRep signaling can be continuously sent.

[0346] Optionally, the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR use the same or different frequency domain resources. For example, as in the scenario of FIG. 2D, the downlink transmission from the DSN to the second device and the uplink transmission from the second device to the UR are in the same frequency resource.

[0347] Optionally, when the ACK signaling (or Msg2) and the QueryRep signaling are continuously sent, the ACK signaling (or Msg2) and the QueryRep signaling can each have an explicit start bit and / or an end bit. Here, the ACK signaling (or Msg2) and the QueryRep signaling can be independently decoded.

[0348] 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.
