[0051] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0052] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using an AIOT device and a network device as an example. Figure 1 illustrates only one AIOT device and one network device as an example, but the present application is not limited thereto, and the communication system may also include other numbers of AIOT devices and network devices.

[0053] As shown in FIG1( a ), the communication system 100 includes a network device 101 and an AIOT device 102. The network device 101 can communicate directly with the AIOT device 102, for example, directly sending a signal to the AIOT device 102 or directly receiving a signal from the AIOT device 102.

[0054] As shown in Figure 1(b), communication system 100 includes network device 101, AIOT device 102, and intermediate node 103. Network device 101 can communicate with AIOT device 102 via intermediate node 103. For example, intermediate node 103 can be used to send signals to AIOT device 102 or receive signals from AIOT device 102. In this topology, intermediate nodes can be relays, IAB nodes, UEs, repeaters, and other devices that can implement ambient IoT functions.

[0055] As shown in Figure 1(c), communication system 100 includes a network device 101, an AIOT device 102, and an auxiliary node 104. With the assistance of auxiliary node 104, network device 101 can send signals to or receive signals from AIOT device 102. In this topology, the auxiliary node can be a relay, IAB, UE, repeater, or other device capable of implementing ambient IoT functions.

[0058] RFID (Radio Frequency Identification) technology, also known as wireless radio frequency identification, is a widely used communication technology that can identify specific targets and read and write related data in a contactless manner. The advantages of RFID systems are low tag cost and small size, making them frequently used in various application scenarios such as logistics information collection, retail, libraries, and identity verification. However, a disadvantage of RFID systems is the limited read range of RFID tags (based on the communication range of wireless signals). With manual handheld tag readers and writers, labor costs can become a major expense. Using dedicated RFID gateways to read and manage RFID tags also incurs high deployment costs. Furthermore, the simple logical architecture of RFID systems prevents effective coordination with interference from radio wave transmissions, resulting in generally low system capacity and spectrum efficiency.

[0059] Compared to RFID systems, support for tag-based terminal devices in 3GPP communication systems allows the reuse of existing base station deployments and supports industry applications based on these devices through existing cellular mobile communication networks, effectively reducing deployment and usage costs. 3GPP communication systems provide reliable authentication, network coordination, and accurate and stable terminal device management mechanisms. These mechanisms can also optimize networks, improve system capacity, and increase spectrum efficiency.

[0060] As a new type of IoT terminal in communication systems, tag-type terminal devices are severely cost-constrained. Their hardware capabilities are significantly inferior to those of standard mobile terminals and other IoT devices supported by existing cellular mobile communication systems. For example, tag-type terminal devices have very limited signal processing capabilities, their onboard crystal oscillators can have large errors, and their ability to achieve precise time and frequency synchronization is relatively poor. Existing communication systems cannot reuse the random access mechanisms for terminal devices. Therefore, how to enable tag-type terminal devices to access communication networks has become a pressing issue.

[0061] In response to at least one of the above problems, embodiments of the present application provide an information processing method, apparatus, and communication system.

[0062] Embodiments of the first aspect

[0063] The present application embodiment provides an information processing method, which is described from the perspective of a terminal device. FIG2 is a schematic diagram of the information processing method of the present application embodiment. As shown in FIG2 , the method includes:

[0064] 201. A terminal device receives a first signal and / or first information sent by a network device, where the first signal is at least used for time synchronization of the terminal device, and the first information includes at least configuration information of the network device.

[0065] 202. The terminal device sends a signal or information on a first resource by backscattering a first waveform.

[0066] According to the above embodiment, the terminal device receives at least a first signal for time synchronization and first information including at least configuration information of the network device from the network device, and the terminal device sends a signal or information on the first resource by backscattering a first waveform. Thus, the terminal device can reliably access the communication network or transmit information in the communication network.

[0067] For example, the terminal device may be a tag-type terminal device, which can send signals or information on time-frequency resources by backscattering a first waveform. Due to the low power consumption and low cost characteristics of the terminal device, the terminal device is not capable of supporting high-precision time-frequency synchronization. The terminal device receives a first signal sent by a network device for at least time synchronization of this type of device, thereby enabling the terminal device to accurately perform time synchronization; and by receiving the first information sent by the network device, the terminal device can obtain the configuration information of the network device. Thus, the terminal device can access the communication network or transmit information in the communication network on the correct time-frequency resources by backscattering the received first waveform, thereby meeting the requirements for accessing tag-type terminal devices in a cellular mobile communication system.

[0068] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0069] In some embodiments, the first signal is used at least for time synchronization of the terminal device, and the time synchronization includes, for example, frame synchronization, subframe synchronization, time slot synchronization, symbol synchronization, or sampling point synchronization, etc. The present application is not limited thereto, and time synchronization may also include synchronization on other time units.

[0070] In some embodiments, the first information includes configuration information of the network device. For example, the first information may include at least one of the following: partial or complete information about an identifier of a cell in which the network device is located or a corresponding cell; partial or complete information about a time unit sequence number, where the time unit sequence number is the sequence number of the time unit in which the first signal and / or the first information is located on the time axis. For example, the time unit sequence number may be a frame number, a subframe number, a time slot number, a symbol number, or a sampling point number.

[0071] In some embodiments, after receiving the first signal and / or the first information, the terminal device transmits an uplink signal and / or information on a first resource. The first resource may include a time domain and / or frequency domain resource, which may be used for at least uplink random access of the terminal device. The present application is not limited thereto, and the first resource may also be used for transmission of other uplink signals or uplink information.

[0072] In some embodiments, the terminal device can determine the position of the corresponding first resource on the time axis and / or frequency axis based on the position of the first signal and / or first information sent by the network device on the time axis and / or frequency axis.

[0073] In the following, the position of the first signal and / or the first information on the time axis and / or the frequency axis and the position of the first resource on the time axis and / or the frequency axis are exemplarily described.

[0074] In some embodiments, the first signal and / or the first information may be sent on one or more first frequency domain resource units (eg, channels), wherein the information of the first frequency domain resource units may be predefined.

[0075] The first signal and / or first information may be the first signal and / or first information of the first cell selected by the terminal device. The first cell may be the cell where the network device is located or the cell corresponding to the network device. For example, the terminal device may receive the first signal and / or first information from one or more first cells, and select a first cell according to a specific implementation (for example, the first cell corresponding to the first signal or first information with the largest detection result level value is selected as the selected first cell), so as to send the signal or information to the selected first cell on the corresponding first resource.

[0076] In some embodiments, when the first signal and / or first information is sent on multiple first frequency domain resource units, the first signal and / or first information can be sent simultaneously on the multiple first frequency domain resource units, that is, the time domain resources for sending the first signal and / or first information on the multiple first frequency domain resource units are at the same position on the time axis. The present application is not limited to this, and the first signal and / or first information can be sent on multiple first frequency domain resource units at different times, that is, the time domain resources for sending the first signal and / or first information on the multiple first frequency domain resource units can also be at different positions on the time axis.

[0077] In some embodiments, one first signal and / or first information may correspond to one or more first resources in the time domain.

[0078] The position of the first resource on the time axis can be referenced to the position of the first signal and / or the first information on the time axis. Thus, even if the terminal device does not support high-precision time-frequency synchronization, the position of the corresponding first resource on the time axis can be determined based on the position of the first signal and / or the first information on the time axis.

[0079] For example, the position of the first resource on the time axis may be indicated by a first offset time, wherein the first offset time may be an offset time of the first resource relative to the first signal and / or the first information.

[0080] In some embodiments, the first offset time uses the position of the first signal and / or first information on the time axis as a reference point, and the reference point may correspond to a starting point or an ending point of the first signal and / or first information on the time axis.

[0081] For example, the reference point may be a starting point or an ending point of the first signal and / or the first information, or a time point determined according to the starting point and / or the ending point of the first signal and / or the first information.

[0082] The first offset time may correspond to a time point or a time range. This can further reduce the requirements for time-frequency synchronization of the terminal device, and contribute to reducing the cost of the terminal device.

[0083] In some embodiments, the first offset time may be an offset time of a first resource relative to the first signal and / or first information.

[0084] For example, the first offset time may be an offset time of a starting point and / or an ending point of a first resource relative to the first signal and / or the first information. Thus, the terminal device can determine the starting point and / or the ending point of the first resource on the time axis based on the first offset time.

[0085] In some embodiments, the first offset time may also be the offset time of a group of first resources relative to the first signal and / or first information. For example, the first offset time may be the offset time of any one first resource in the group of first resources relative to the first signal and / or first information. For example, the any one first resource may be the first first resource, the last first resource, or an intermediate first resource in the group of first resources. In this case, the position of each first resource in the group on the timeline may also be indicated by a third interval time.

[0086] The third interval time may be an offset time of a first resource relative to other first resources in the plurality of first resources. For example, the third interval time may include an offset time of a starting point and / or an ending point of a first resource relative to other first resources.

[0087] In some embodiments, the third interval time uses the position of the other first resource on the time axis as a reference point, and the reference point corresponds to the starting point or the ending point of the other first resource on the time axis.

[0088] For example, the reference point may be a starting point or an ending point of other first resources, or a time point determined according to the starting point and / or the ending point of other first resources.

[0089] The third interval time may correspond to a time point or a time range. Thus, the requirements for time-frequency synchronization of the terminal device can be further reduced, which helps to reduce the cost of the terminal device.

[0090] The other first resource may be a previous first resource of the first resource, or the other first resource may be the first first resource among multiple first resources.

[0091] In some embodiments, the position of the first resource on the time axis may also be indicated by a second duration, which is the duration of the first resource, that is, the time between the start point and the end point of the first resource.

[0092] In some embodiments, the second duration may correspond to a value. The present application is not limited thereto, and the second duration may also correspond to a value range, thereby further reducing the requirements for time-frequency synchronization of the terminal device and contributing to low-cost terminal devices.

[0093] In some embodiments, at least one of the number of first resources, the first offset time, the second duration, and the third interval time corresponding to a first signal and / or first information may be predefined. For example, at least one of the above information may be related to partial or full information about the identifier of the first cell.

[0094] The present application is not limited thereto, and at least one of the above-mentioned information may also be carried in the first information. For example, the configuration information in the first information includes at least one of the above-mentioned information. Thus, after receiving the first information, the terminal device can determine the location of the corresponding first resource based on the above-mentioned information carried in the first information.

[0095] In some embodiments, the number of first resources and / or the first offset time and / or the second duration and / or the third interval time corresponding to multiple first signals and / or first information may be the same. For example, the number of first resources, the first offset time, the second duration and the third interval time corresponding to multiple first signals and / or first information on the time axis may be the same. The present application is not limited to this, and the number of first resources and / or the first offset time and / or the second duration and / or the third interval time corresponding to multiple first signals and / or first information may also be different.

[0096] In some embodiments, a first signal and / or first information may correspond to a first resource on one or more second frequency domain resource units.

[0097] In some embodiments, the second frequency domain resource unit may be the same as the first frequency domain resource unit in which the first signal and / or the first information is located. For example, the number of the second frequency domain resource units is the same as the number of the first frequency domain resource units, and / or the position of the second frequency domain resource unit on the frequency axis is the same as the position of the first frequency domain resource unit on the frequency axis. Thus, the terminal device can determine the second frequency domain resource unit in which the first resource is located based on the first frequency domain resource unit.

[0098] For example, the first signal and / or the first information is sent on a first frequency domain resource unit, and the first resource is located on a second frequency domain resource unit, which is the same as the first frequency domain resource unit.

[0099] For another example, the first signal and / or first information is sent on multiple first frequency domain resource units, and the first resources are located on multiple second frequency domain resource units, which are the same as the multiple first frequency domain resource units.

[0100] In some embodiments, the second frequency domain resource unit may be different from the first frequency domain resource unit. For example, the number of the second frequency domain resource units is different from the number of the first frequency domain resource units, and / or the position of the second frequency domain resource unit on the frequency axis is different from the position of the first frequency domain resource unit on the frequency axis.

[0101] In some embodiments, the position of the second frequency domain resource unit on the frequency axis may be predefined. Alternatively, the position of the second frequency domain resource unit on the frequency axis may also be carried in the first information, whereby the terminal device may determine the second frequency domain resource unit based on the first information after receiving the first information.

[0102] In some embodiments, on a second frequency domain resource unit, a first signal and / or first information may correspond to one or more first resources in the time domain.

[0103] In the case where a first signal and / or first information corresponds to first resources on multiple second frequency domain resource units, a first signal and / or first information can correspond to multiple second frequency domain resource units and multiple first resources on the time domain, the number of first resources on the multiple second frequency domain resource units can be the same or different, and / or the positions of the first resources on the multiple second frequency domain resource units on the time axis can be the same or different.

[0104] The position of the first resource on each second frequency domain resource unit on the time axis can be determined in the manner described above. For example, it can be determined based on at least one of the first offset time, the second duration, and the third interval time. The first offset time here can be the offset time of the first resource relative to the corresponding first signal and / or first information, and the second frequency domain resource unit where the first resource is located and the first frequency domain resource unit where the corresponding first signal and / or first information is located can be the same frequency domain resource unit. The third interval time here can be the offset time of the first resource relative to other first resources in a plurality of first resources, and the first resource and other first resources can be located in the same second frequency domain resource unit. The present application is not limited to this, and the second frequency domain resource unit where the first resource is located and the first frequency domain resource unit where the corresponding first signal and / or first information is located can also be different frequency domain resource units, or the first resource and other first resources can also be located in different second frequency domain resource units.

[0105] The following, in conjunction with the accompanying drawings, provides an exemplary description of the time-frequency resources of the first signal and / or first information, and the positional relationship of the first resources. In the accompanying drawings, the larger blank rectangles represent the time-frequency resources of the first signal, the shaded rectangles represent the time-frequency resources of the first information, and the smaller blank rectangles represent the first resources. These different shapes or patterns are used only to distinguish and represent the various types of resources and are not used to limit information such as the size of the resources.

[0106] Figure 3 is a schematic diagram of the time-frequency resources and positional relationship of the first signal and / or first information in an embodiment of the present application. As shown in Figure 3, the terminal device receives the first signal and / or first information in a channel (frequency domain resource unit) and sends an uplink signal / information on the first resource in the channel.

[0107] From a timeline perspective, the first resource follows the first signal and / or first information. One first signal and / or first information corresponds to one or more first resources. The number of first resources can be predefined or configured via the first information.

[0108] As shown in Figure 3, one first signal and / or first information corresponds to M first resources. The terminal device selects one of the first resources to send an uplink signal / information to perform uplink random access.

[0109] For different first signals and / or first information, the number of first resources corresponding thereto may be the same or different. As shown in FIG3 , one first signal and / or first information corresponds to M first resources, and another first signal and / or first information corresponds to N first resources, where M and N may be the same or different.

[0110] In some embodiments, the one or more first resources are determined by their position information on the timeline. The position is based on the position of the first signal and / or first information on the timeline as a reference point, and a set of parameters is used to define the relative position of the first resource (relative to the position of the first signal and / or first information on the timeline).

[0111] For example, for a first resource, the time domain resource corresponding to the first resource is obtained by defining its first offset time mi (1≤i≤M) and the second duration parameter Di (1≤i≤M) relative to the first signal and / or first information on the time axis; or, the time domain resource corresponding to the first resource can also be determined by defining the first offset time m1 of the first first resource relative to the first signal and / or first information on the time axis, the third interval time Ti (1≤i≤M-1) between the subsequent first resource and the previous first resource, and the second duration Di (1≤i≤M) of the first resource.

[0112] The first offset time, the second duration time, and the third interval time may each be a numerical value or correspond to a value range, which may be given by a set of parameters, such as a minimum value and a maximum value.

[0113] In some embodiments, the location information of one or more first resources on the timeline can be obtained in a predefined manner. Alternatively, the location information of one or more first resources on the timeline can be carried in the corresponding first information, for example, the first information includes a parameter list indicating the location information of each first resource on the timeline.

[0114] Figure 4 is another schematic diagram of the time-frequency resources and positional relationship of the first signal and / or first information in an embodiment of the present application. As shown in Figure 4, the network device can send the first signal and / or first information separately in multiple channels. The network device can send the first signal and / or first information simultaneously in multiple channels, or the network device can send the first signal and / or first information at different times.

[0115] For example, the first signals and / or first information corresponding to channel #1 and channel #2 are sent simultaneously, while the first signals and / or first information corresponding to channel #1 and channel #K are not sent simultaneously.

[0116] After the terminal device receives the first signal and / or first information from multiple channels, it selects a channel according to its implementation algorithm and sends an uplink signal / information on the first resource of the channel. The first resource in the channel corresponds to the first signal and / or first information received on the channel. In other words, the first resource on a channel can be independently configured or predefined, that is, the parameter information corresponding to the first resource on a channel, such as the number of first resources and the position information of the first resource on the time axis can be predefined or configured through the first information on the channel. For example, as mentioned above, the time domain resource corresponding to the first resource can be determined by at least one of the first offset time, the second duration and the third interval time. For related content, please refer to the above content and will not be elaborated here.

[0117] In some embodiments, the first signal and / or first information received by the terminal device and the first resource corresponding to the first signal and / or first information may be in the same channel. The present application is not limited thereto, and the first signal and / or first information and the first resource corresponding thereto may also be in different channels. In this case, the first information may carry channel information (e.g., a channel identifier) ​​of the corresponding first resource.

[0118] As shown in Figure 4, a first signal and / or first information in channel #1 and its corresponding first resource are in the same channel. Another first signal and / or first information in channel #1 and its corresponding first resource are in different channels. In this case, the first information in channel #1 can carry channel information of the corresponding first resource, for example, identification information of channel #2.

[0119] Figure 5 is another schematic diagram of the time-frequency resources of the first signal and / or first information and the positional relationship of the first resource in an embodiment of the present application. As shown in Figure 5, the network device can send the first signal and / or first information in one of multiple channels, that is, multiple channels share the first signal and / or first information of a channel in the frequency domain. As for which channel the first signal and / or first information shared by multiple channels comes from, this application does not impose any restrictions. For example, the shared channel can be determined in a predefined manner. For example, the shared channel can be a channel in the middle of K consecutive channels, or a channel with the lowest channel identifier.

[0120] The terminal device searches for and detects the first signal and / or first information on the shared channel in multiple channels. After detecting the first signal and / or first information on the shared channel, the terminal device sends an uplink signal / information on the corresponding first resource.

[0121] A first signal and / or first information corresponds to multiple first resources, wherein a first signal and / or first information corresponds to resources in the frequency domain in addition to resources in the time domain. As shown in FIG5 , the time-frequency resources corresponding to a first signal and / or first information include frequency domain resources of K channels, each channel having M i (i=1….K) time domain resources.

[0122] In the frequency domain, the number of channels and channel-related information (eg, channel identifiers, etc.) can be determined in a predefined manner or carried in the first information.

[0123] In the time domain, the number of time domain resources within a channel can be the same or different, and this application does not impose any restrictions. The number of time domain resources on each channel can be determined in a predefined manner or carried in the first information. For example, as described above, the time domain resource corresponding to the first resource can be determined by at least one of the first offset time, the second duration, and the third interval time. For related details, please refer to the above content and will not be further explained here.

[0124] The timeline location information of the first resource can be the same or different across multiple channels. As shown in Figure 5 , for a first signal and / or first information, the first offset time of the first resource relative to the first signal and / or first information on the timeline is the same in channels #1 and #K, while the first offset time of the first resource relative to the first signal and / or first information on the timeline is different in channels #1 and #2.

[0125] The above is an exemplary description of the positional relationship between the time-frequency resource and the first resource based on the first signal and / or the first information. The present application is not limited thereto. In some embodiments, the terminal device may also determine the position of the corresponding first resource on the time axis and / or frequency axis based on the position of the received first waveform on the time axis and / or frequency axis.

[0126] The following is an exemplary description of the position of the first waveform on the time axis and / or the frequency axis and the position of the first resource on the time axis and / or the frequency axis.

[0127] In some embodiments, the first waveform received by the terminal device may come from a network device. The present application is not limited thereto, and the first waveform may also come from other devices controlled by the network device.

[0128] The first waveform may be a carrier wave, a continuous wave, a backscattered / backscattering wave, an uplink wave, etc., but the present application is not limited thereto.

[0129] In some embodiments, the first waveform includes at least a single-frequency signal with a constant envelope. The present application is not limited thereto. For example, the bandwidth of the first waveform is significantly narrower than the bandwidth of the first signal. For example, the bandwidth of the first waveform is 1 kHz, and the bandwidth of the first signal is 100 kHz, as an example only.

[0130] In some embodiments, the frequency point of the first waveform includes at least one frequency point in a frequency range corresponding to one or more frequency domain resource units. For example, the frequency point may be a center frequency point of the one or more frequency domain resource units.

[0131] In some embodiments, the one or more frequency domain resource units may be frequency domain resource units used to send the first signal or the first information. This can reduce the frequency domain range that the terminal device needs to support, thereby facilitating low-cost terminal devices.

[0132] In some embodiments, the first waveform may be continuous on the time axis. The present application is not limited thereto, and the first waveform may also be discontinuous on the time axis. For example, the first waveform is sent only when the terminal device needs to send an uplink signal or uplink information.

[0133] It should be noted that in the embodiments shown in Figures 3-5, it can be assumed that the first waveform is transmitted continuously in the time domain. When multiple channels are allocated, each channel can have its own first waveform, or multiple channels can share a first waveform. The present application is not limited to this. In the above embodiments, it can also be assumed that the first waveform is transmitted discontinuously in the time domain.

[0134] In some embodiments, there may be a corresponding relationship between the first waveform and the first resource, whereby the first waveform can indicate the position of the first resource on the time axis and / or frequency axis, thereby enabling the terminal device to send a signal or information on the first resource corresponding to the first waveform by backscattering the first waveform.

[0135] In some embodiments, the first waveform and the first resource may have various corresponding relationships. For example, a first waveform may correspond to one or more first resources. For example, a first waveform may correspond to a first resource on one or more frequency domain resource units. A first waveform may be a continuous waveform in a first waveform transmitted continuously or discontinuously.

[0136] In some embodiments, the position of the first waveform on the time axis may correspond to the position of the first resource on the time axis.

[0137] For example, the first waveform may appear T time units earlier than the first resource. Thus, after the terminal device detects the first waveform, it can determine that the first resource is located at a position that is T time units offset from the first waveform. T may be a predefined value, or may be a value related to the processing time of the terminal device.

[0138] In some embodiments, the duration of the first waveform may be greater than the duration of the first resource. This ensures the integrity of the transmitted signal and / or information. For example, the duration of the first waveform may be greater than or equal to the sum of the duration of the first resource and T time units.

[0139] In some embodiments, the terminal device can determine the position of the corresponding first waveform on the time axis and / or frequency axis based on the position of the first signal and / or first information sent by the network device on the time axis and / or frequency axis. In other words, the position of the first waveform on the time axis can be based on the first signal and / or first information. Thus, even if the terminal device does not support high-precision time-frequency synchronization, it can determine the position of the corresponding first waveform on the time axis based on the position of the first signal and / or first information on the time axis. The position of the first waveform on the time axis may include at least one of the starting point information, end point information and duration information of the first waveform on the time axis.

[0140] For example, the position of the first waveform on the time axis can be indicated by at least one of the following parameters:

[0141] a fourth offset time, where the fourth offset time may be an offset time of the first waveform relative to the first signal and / or the first information;

[0142] a fifth duration, which may be the duration of the first waveform;

[0143] The sixth interval time may be an offset time of the first waveform relative to other first waveforms in the plurality of first waveforms.

[0144] The fourth offset time, the fifth duration time and the sixth interval time are similar to the first offset time, the second duration time and the third interval time, and are not further described here.

[0145] In some embodiments, the first waveform may be sent on one or more third frequency domain resource units. The number of the third frequency domain resource units and / or the position of the third frequency domain resource units on the frequency axis may be predefined. The present application is not limited thereto, and the number of the third frequency domain resource units and / or the position of the third frequency domain resource units on the frequency axis may also be carried in the first information.

[0146] In the case where the first waveform is sent on multiple third frequency domain resource units, the number of first waveforms on the multiple third frequency domain resource units may be the same or different, and / or the positions of the first waveforms on the multiple third frequency domain resource units on the time axis may be the same or different.

[0147] In some embodiments, the third frequency domain resource unit where the first waveform is located may be the same as the first frequency domain resource unit where the first signal and / or the first information is located. For example, the number of third frequency domain resource units is the same as the number of first frequency domain resource units, and / or the position of the third frequency domain resource unit on the frequency axis is the same as the position of the first frequency domain resource unit on the frequency axis. Thus, the terminal device can determine the third frequency domain resource unit where the first waveform is located based on the first frequency domain resource unit.

[0148] For example, the first signal and / or the first information is sent on a first frequency domain resource unit, and the first waveform is located on a third frequency domain resource unit, which is the same as the first frequency domain resource unit.

[0149] For another example, the first signal and / or first information is sent on multiple first frequency domain resource units, and the first waveform is located on multiple third frequency domain resource units, which are the same as the multiple first frequency domain resource units.

[0150] In some embodiments, the third frequency domain resource unit may be different from the first frequency domain resource unit. For example, the number of the third frequency domain resource units is different from the number of the first frequency domain resource units, and / or the position of the third frequency domain resource unit on the frequency axis is different from the position of the first frequency domain resource unit on the frequency axis.

[0151] In some embodiments, the third frequency domain resource unit where the first waveform is located may be the same as or different from the second frequency domain resource unit where the first resource is located.

[0152] The position of the second frequency domain resource unit where the first resource is located on the frequency axis may be predefined. The present application is not limited thereto, and the position of the second frequency domain resource unit where the first resource is located on the frequency axis is also carried in the first information. For example, the position of the first resource on the time axis is indicated by the first waveform, the position of the first resource on the frequency domain axis is indicated by the first information, and so on.

[0153] The following is an exemplary description of the time-frequency resources of the first waveform and the positional relationship of the first resources, in conjunction with the accompanying drawings. The larger blank rectangles in the accompanying drawings represent the time-frequency resources of the first signal, the rectangles with horizontal hatching represent the time-frequency resources of the first information, the smaller blank rectangles represent the first resources, and the rectangles with grid hatching represent the time-frequency resources of the first waveform. The above different shapes or patterns are only used to distinguish and represent various types of resources and are not used to limit information such as the size of the resources.

[0154] Figure 6 is a schematic diagram of the time-frequency resources of the first waveform and the positional relationship of the first resource in an embodiment of the present application. As shown in Figure 6, the terminal device receives a first signal and / or a first information in a channel, and also receives a first waveform on the channel, and sends an uplink signal / information on the first resource corresponding to the first waveform. Among them, one first waveform can correspond to one first resource. For example, the position information and / or duration of one or more first resources corresponding to a first signal and / or first information on the time axis can be indicated by the first waveform. That is, the position and / or duration of a controlled first waveform on the time axis corresponds to the position and / or duration of a first resource on the time axis.

[0155] In some embodiments, a first waveform and its corresponding uplink signal may also satisfy certain constraints. Figure 7 is another schematic diagram of the time-frequency resources of the first waveform and the positional relationship of the first resource in an embodiment of the present application. As shown in Figure 7, on the time axis, the first waveform appears T time units earlier than the uplink signal, and its duration may be greater than or equal to the sum of the duration of the uplink signal and T, that is, d1≥d2+T. When a first waveform satisfies the above conditions, the first waveform is a valid first waveform and can correspond to a first resource. Otherwise, the first waveform is an invalid first waveform and cannot correspond to a first resource.

[0156] In some embodiments, the network device can control the position and duration of each first waveform on the time axis. For example, the network device can control this using a set of parameters. The set of parameters may include at least one of the following: the duration of the first waveform (fifth duration), the interval between two first waveforms (sixth interval), and the offset time relative to the first signal and / or first information (fourth offset time). For specific parameter information, please refer to the above content and will not be further described here.

[0157] In some embodiments, for a discontinuous first waveform controlled by a network device, the first information may not include the position information of the first resource on the time axis. That is, the position information of the first resource on the time axis can be determined by the first waveform.

[0158] Figure 8 is another schematic diagram of the time-frequency resources of the first waveform and the positional relationship of the first resources according to an embodiment of the present application. As shown in Figure 8, the network device transmits the first signal and / or the first information in multiple channels respectively, and the network device also controls the first waveform to be transmitted in the multiple channels respectively.

[0159] After receiving the first signal and / or first information in multiple channels, the terminal device selects a channel according to its implementation algorithm, receives the first waveform in the channel, and sends an uplink signal / information on the first resource in the channel.

[0160] In a channel, the position and / or duration of one or more first resources corresponding to a first signal and / or first information on the time axis can be indicated by the first waveform in the channel. That is, in a channel, the position and / or duration of a first waveform on the time axis corresponds to the position and / or duration of a first resource on the channel on the time axis. The network device can control the first waveform separately by channel, for example, separately controlling the position and / or duration of each first waveform on the time axis of each channel.

[0161] In some embodiments, the positions and / or durations of the first waveforms on the multiple channels controlled by the network device may be the same or different on the time axis. As shown in FIG8 , the positions of the first waveforms on the time axis of channel #1 and channel #2 are the same, while the positions of the first waveforms on the time axis of channel #1 and channel #K are different.

[0162] FIG9 is another schematic diagram of the time-frequency resources and positional relationship of the first waveform in an embodiment of the present application. As shown in FIG9 , the first waveform in channel #1 and channel #2 has the same position on the time axis, while the second waveform in channel #1 and channel #2 has a different position on the time axis.

[0163] In some embodiments, the first signal and / or first information and the corresponding first resource may not be in the same channel. For a first signal and / or first information, the network device may also provide the terminal device with first resources of different channels by controlling the first waveforms of different channels. In this case, the first information may carry channel information (e.g., a channel identifier) ​​corresponding to the corresponding first resource.

[0164] As shown in Figures 8 and 9, a first signal and / or first information is in channel #1, and its corresponding first resource is in channel #2, wherein the first information includes channel information of the corresponding first resource (e.g., information of channel #2). The network device can control the position and / or duration of the first waveform on the time axis in channel #2.

[0165] FIG10 is another schematic diagram of the time-frequency resources of the first waveform and the positional relationship of the first resource in an embodiment of the present application. As shown in FIG10 , the network device sends the first signal and / or the first information in multiple channels respectively, and controls the first waveform to be sent in one of the multiple channels. After the terminal device receives the first signal and / or the first information in multiple channels, it selects a channel according to its implementation algorithm. The terminal device also receives the first waveform and sends an uplink signal / information on the corresponding first resource.

[0166] As shown in Figure 10, the position of one or more first resources corresponding to a first signal and / or first information on the time axis can be indicated by a first waveform shared by multiple channels. That is, in a channel, the position and / or duration of the shared first waveform on the time axis corresponds to the position and / or duration of a first resource on the channel on the time axis. Among them, the first resources on different channels can be indicated by a shared first waveform. In this case, the position of the first resources corresponding to the first signals and / or first information on different channels on the time axis can be determined based on the position of the first signal and / or first information on the time axis and the position of the first waveform on the time axis.

[0167] For example, a network device simultaneously transmits a first signal and / or first information in different channels, and the positions of the first resources corresponding to these first signals and / or first information on the time axis may be the same. As shown in Figure 10, a network device simultaneously transmits a first signal and / or first information in channel #1 and channel #2, and the positions of the first resources corresponding to the first signal and / or first information in channel #1 and the first resources corresponding to the first signal and / or first information in channel #2 on the time axis are the same.

[0168] For another example, if a network device transmits first signals and / or first information at different times in different channels, the position of the first resources corresponding to each first signal and / or first information on the time axis can be determined based on the shared first waveform transmitted after the first signal and / or first information. As shown in Figure 10, if a network device transmits first signals and / or first information at different times in channels #2 and #K, the positions of the M2 first resources in channel #2 on the time axis are sequentially determined based on the shared first waveform (corresponding to channel #1) transmitted after the first signal and / or first information in channel #2; and the positions of the MK first resources in channel #K on the time axis are sequentially determined based on the shared first waveform (corresponding to channel #1) transmitted after the first signal and / or first information in channel #K. For example, the first first resource of channel #K is aligned with the M1th first resource of channel #1, the second first resource of channel #K is aligned with the first first resource of the next first channel and / or first information in channel #1 (located in channel #2), and so on.

[0169] In some embodiments, the channel selected by the terminal device for transmitting the uplink signal / information and the first waveform received may not be on the same channel. As shown in Figure 10, after receiving the first signal and / or first information from multiple channels, the terminal device selects the first resource in channel #2 to transmit the uplink signal / information according to its implementation algorithm. The first waveform received by the terminal device is on channel #1.

[0170] Figure 11 is another schematic diagram of the time-frequency resources of the first waveform and the positional relationship of the first resources in an embodiment of the present application. As shown in Figure 11, the network device transmits the first signal and / or first information on one of the multiple channels. As to which channel the first signal and / or first information shared by the multiple channels originates from, this application does not impose any restrictions. For example, the shared channel can be determined in a predefined manner, etc.

[0171] In this case, the first resources corresponding to a first signal and / or first information may include both corresponding time domain resources and frequency domain resources. The number of time domain resources and / or frequency domain resources may be determined in a predefined manner or carried in the first information.

[0172] In some embodiments, the network device transmits the first signal and / or the first information in one of a plurality of channels, and controls the first waveform to be transmitted in the plurality of channels respectively.

[0173] After searching for and detecting the first signal and / or first information on the shared channel in multiple channels, the terminal device also receives the first waveform in multiple channels and sends an uplink signal / information on the corresponding first resource.

[0174] In a channel, the position of one or more first resources corresponding to the first signal and / or first information on the time axis may be indicated by a first waveform in the channel. That is, in a channel, the position and / or duration of a controlled first waveform on the time axis corresponds to the position and / or duration of a first resource on the channel on the time axis.

[0175] The network device can control the first waveform separately according to the channel, for example, controlling the position and duration of each first waveform of each channel on the time axis. In multiple channels, the position of the first waveform on the time axis can be the same or different.

[0176] In some embodiments, if a first waveform controlled by a network device is not transmitted on one of the channels, it can be considered that the channel does not have a corresponding first resource. In other words, even if the channel is included in the predefined or configured channel resources, if the first waveform is not transmitted on the channel, it can be considered that the channel does not have a corresponding first resource.

[0177] Figure 12 is another schematic diagram of the time-frequency resources and positional relationship of the first waveform in an embodiment of the present application. As shown in Figure 12, the network device transmits the first signal and / or first information in one of the multiple channels and controls the first waveform to be transmitted in one of the multiple channels.

[0178] The terminal device searches for and detects a first signal and / or first information on a plurality of channels. After detecting the first signal and / or first information, the terminal device further receives a first waveform and sends an uplink signal / information on a corresponding first resource.

[0179] In this case, the first resource corresponds to multiple time domain resources and also corresponds to multiple frequency domain resource units (e.g., channels). In a channel, the position of one or more first resources corresponding to a first signal and / or first information on the time axis can be indicated by a shared first waveform. Since the first resource in each channel corresponds to the first signal and / or first information sent by a channel and is indicated by the first waveform in a channel, the position of the first resource in each channel on the time axis is the same.

[0180] In some embodiments, the shared first signal and / or first information and the shared first waveform can be in the same channel. As shown in FIG12 , the shared first signal and / or first information and the shared first waveform are both in channel #1. The present application is not limited thereto, and the shared first signal and / or first information and the shared first waveform can also be in different channels.

[0181] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0182] According to the above embodiment, the terminal device receives at least a first signal for time synchronization and first information including at least configuration information of the network device from the network device, and the terminal device sends a signal or information on the first resource by backscattering a first waveform. Thus, the terminal device can reliably access the communication network or transmit information in the communication network.

[0183] Embodiments of the second aspect

[0184] The embodiment of the present application provides an information processing device, which may be, for example, a terminal device, or one or more components or assemblies configured in the terminal device, and the same contents as those in the embodiment of the first aspect will not be repeated here.

[0185] FIG13 is a schematic diagram of an information processing device according to an embodiment of the present application. As shown in FIG13 , the information processing device 1300 includes a receiving unit 1301 and a sending unit 1302 .

[0186] The receiving unit 1301 receives a first signal and / or first information sent by a network device, where the first signal is at least used for time synchronization of the terminal device, and the first information at least includes configuration information of the network device; the sending unit 1302 sends a signal or information on a first resource by backscattering a first waveform.
