[0047] The embodiments of the technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present disclosure, and therefore only serve as examples, and cannot limit the protection scope of the present disclosure.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure; the terms "include" and "have" and any variations thereof in the specification and claims of the present disclosure and the above description of drawings are intended to cover non-exclusive inclusion.

[0049] In the description of the embodiments of the present disclosure, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present disclosure, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0050] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the disclosure. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common set of embodiments, of the other embodiments. Those skilled in the art will appreciate that embodiments described herein can be combined with other embodiments in various ways.

[0051] In the description of the embodiments of the disclosure, the term“and / or” only means an association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character“ / ” herein generally represents an“or” relationship between the front and rear associated objects.

[0052] Many international organizations are researching new wireless communication systems (6G), and the important driving force is the growth of the number of access terminals, mainly machine-type devices, and the density of terminals per square kilometer can reach millions of terminals.

[0053] The initial access and data transmission of a large number of terminals are limited by network coordination signaling and data transmission resources. Using ordinary contention access technology cannot accommodate so many terminals, and each random access resource occupies 1 physical resource block (PRB) of resources. So many terminals require tens of thousands of PRBs or more, far exceeding the total number of system PRBs. In addition, traditional random access resources are only used for random access. Even if no terminal uses the resource for random access, it cannot be used for data transmission, which will consume a large amount of system resources and is not efficient.

[0054] Ultra Wideband (UWB) is a technology that transmits low power density signals in a large bandwidth to achieve communication. It is defined as an absolute bandwidth of 500MHz or more or a relative bandwidth of 20% or more (this is the definition of UWB technology approved by FCC for civilian use in February 2002) under the condition that the amplitude attenuation is-10dB. The purpose of UWB is to achieve frequency multiplexing by transmitting signals with low transmit power spectral density (not more than-41.3dBm) over an extremely wide bandwidth, and these frequencies may be allocated to other systems.

[0055] The Federal Communications Commission (FCC) has mandated that UWB technology can transmit signals in the bandwidth of 3.1GHz to 10.6GHz with a transmit power spectral density no higher than -41.3dBm. In the frequency band of 3.1GHz to 10.6GHz, there are frequency bands used for satellite communication, and Unlicensed National Information Infrastructure (U-NII) and Industrial, Scientific and Medical (ISM) bands. When UWB uses these bands, it cannot interfere with the normal communication of the existing communication systems in the bands, nor can it require any coordination or concession from these communication systems for the use of UWB. Therefore, the transmit power spectral density of UWB in these bands is required to be no higher than -41.3dBm.

[0056] The frequency domain resources allocated for UWB use and the corresponding power spectral density limits are different in each country. For example, in China, they are shown in Table 1 below:

[0057] Table 1

[0058]

[0059] As shown in Table 1 above, for the current regulations in China, the frequency band that can be used for UWB is 6GHz-9GHz. Other frequency bands can also use UWB technology, but the power spectral density is lower and the transmit power is more limited. The Ministry of Industry and Information Technology updated the "Ultra-Wideband (UWB) Device Radio Management Regulations" in 2023, updating the UWB spectrum to 7235-8750MHz.

[0060] Currently, the implementation technologies of UWB mainly include two categories:

[0061] Pulse UWB: In this mode, data transmission is performed by sending pulses with extremely narrow width (for example, 0.2ns-1.5ns). Because the pulse width is extremely narrow, the bandwidth of the signal is very wide. The modulation method is pulse modulation, that is, information is transmitted directly by modulating the width, amplitude, position or presence or absence of the pulse.

[0062] Multi-Band OFDM UWB (MB-OFDM UWB): This technology divides the frequency domain resources allocated for UWB use into multiple band groups (Band Group), each of which includes multiple sub-bands (Band), and each sub-band has a bandwidth of 528MHz. In actual use, the time-frequency code (TFC) is used to control which sub-band to transmit data.

[0063] As shown in FIG. 1, it is a sub-band division diagram of a multi-band UWB. In the sub-band division diagram, the frequency is divided into a plurality of band groups in the frequency (f) latitude represented by the horizontal axis, and the vertical axis in FIG. 1 has no actual meaning. Each of the band groups includes 2 sub-bands or 3 sub-bands, such as Band Group #1, Band Group #2, Band Group #3, Band Group #4, and Band Group #5 in FIG. 1. The sub-bands included in FIG. 1 include Band #1, Band #2, Band #3, Band #4, Band #5, Band #6, Band #7, Band #8, Band #9, Band #10, Band #11, Band #12, Band #13, and Band #14.

[0064] As shown in FIG. 2, it is a sub-band use diagram of a multi-band UWB. In FIG. 2, the frequency band 1 is used for the first transmission, the frequency band 2 is used for the second transmission, and the frequency band 3 is used for the third transmission, where the frequency band 1, the frequency band 2, and the frequency band 3 are different sub-bands. In FIG. 2, IFFT represents Inverse Fast Fourier Transform, and OFDM represents Orthogonal Frequency Division Multiplexing.

[0065] In the face of 6G massive access, the currently proposed technology is a non-coordinated random access technology, which cancels most of the coordination between the terminal and the network, and can support the scene of a large number of terminals. Compared with the traditional random access mechanism, although the resource efficiency is improved, the technology still uses the frequency resources of the mobile communication network, and the resources allocated to the non-coordinated random access can still only be used for random access.

[0066] In the embodiments of the present disclosure, referring to the UWB technology, an access mechanism based on ultra-wideband is realized in the mobile communication network: configuring ultra-wideband resources for random access; realizing coexistence of ultra-wideband-based random access and traditional random access methods. Of course, the ultra-wideband resources configured in the mobile communication network can also be used for data and signaling transmission, such as the transmission of subsequent signaling, channels, signals, or data, etc. after completing network access.

[0067] The messaging method of the embodiments of the present disclosure, the terminal can receive the first resource configuration, and the terminal can transmit information on the first resource indicated by the first resource configuration, wherein the bandwidth of the first resource is greater than or equal to a preset bandwidth threshold, and / or the power spectral density of the information transmitted on the first resource is less than or equal to a preset power spectral density threshold. Through this scheme, the bandwidth of the first resource is large enough, and the power spectral density of the information transmitted on the first resource is small enough, which improves the resource utilization efficiency. For example, even if the first resource overlaps or partially overlaps with a resource (such as a random access resource, a data transmission resource, etc.) defined by a mobile communication network and having a relatively small bandwidth, the first resource can still be used for random access or other data transmission.

[0068] In the embodiments of the present disclosure, the network device can be an access network device, which can be a base station, an evolved base station (eNB), a base station in a 5G, 6G and future X-G network, a satellite, etc. X in X-G can be 7, 8 and more, which can represent the "generation" number of the evolution or iteration of the communication system. For example, there can be a 7th generation communication system, an 8th generation communication system, etc. in the future. The following description is similar and will not be described additionally.

[0069] In the embodiments of the present disclosure, the terminal can be a user equipment (User Equipment, UE), which is also called a terminal device. Exemplarily, the terminal can include but is not limited to a smartphone, a computer, a vehicle-mounted terminal, a smart home device, a wearable device, etc.

[0070] It should be noted that in the embodiments of the present disclosure, the first resource refers to a type of resource, and the second resource refers to another type of resource.

[0071] FIG. 3 is a flow diagram of a messaging method provided by the embodiments of the present disclosure, which includes but is not limited to the following steps:

[0072] 301. The first network device sends a first resource configuration to the terminal.

[0073] Correspondingly, the terminal receives the first resource configuration sent by the first network device.

[0074] The first resource configuration is used to indicate the first resource.

[0075] 302. The terminal transmits information on the first resource indicated by the first resource configuration.

[0076] Correspondingly, the first network device transmits information on the first resource.

[0077] The bandwidth of the first resource is greater than or equal to a preset bandwidth threshold, and / or the power spectral density of the information transmitted on the first resource is less than or equal to a preset power spectral density threshold.

[0078] The above information can include, but is not limited to, any one of the following: signaling, a channel, a signal, data.

[0079] In some embodiments, the messaging method in the embodiments of the present disclosure further includes: the terminal determines to have the capability to support the transmission of information based on the first resource.

[0080] In some embodiments, when the terminal determines to have the capability to support the transmission of information based on the first resource, the terminal transmits information on the first resource indicated by the first resource configuration.

[0081] In some embodiments, the terminal transmits information on the first resource indicated by the first resource configuration can include, but is not limited to: the terminal receives information on the first resource indicated by the first resource configuration, or the terminal transmits information on the first resource indicated by the first resource configuration.

[0082] The power spectral density of the information transmitted on the first resource is less than or equal to a preset power spectral density threshold, which can include, but is not limited to: the power spectral density of the information received on the first resource is less than or equal to a preset power spectral density threshold, or the transmit power spectral density of the information transmitted on the first resource is less than or equal to a preset power spectral density threshold.

[0083] In some embodiments, the bandwidth of the first resource satisfies at least one of the following conditions:

[0084] (1) The absolute bandwidth of the first resource is greater than a first bandwidth threshold.

[0085] For example, the absolute bandwidth of the first resource is greater than -10 dB absolute bandwidth 500 MHz, that is, the first bandwidth threshold is -10 dB absolute bandwidth 500 MHz. For example, such a resource can be referred to as a super wideband resource.

[0086] It should be noted that the first bandwidth threshold can also be set to -10 dB absolute bandwidth 400 MHz or -10 dB absolute bandwidth 300 MHz. For example, such a resource can be referred to as a super wideband resource. The first bandwidth threshold can also be set according to actual needs, and the embodiments of the present disclosure are not limited.

[0087] (2) The relative bandwidth of the first resource is greater than a second bandwidth threshold.

[0088] For example, the relative bandwidth of the first resource is greater than 20%, that is, the second bandwidth threshold is 20%.

[0089] It should be noted that the second bandwidth threshold can also be set to 15% or 18%, and the second bandwidth threshold can also be set according to actual needs, and the embodiments of the present disclosure are not limited.

[0090] (3) The bandwidth of the first resource is greater than the bandwidth of the second resource.

[0091] In some embodiments, the first resource can be a resource based on ultra-wideband or ultra-wideband-like; the second resource can be a resource not based on ultra-wideband or a resource not based on ultra-wideband-like.

[0092] The above-mentioned resource based on ultra-wideband can be a resource currently allocated to a UWB system, for example, 3.1 GHz-10.6 GHz allocated in the United States. It can also be a resource allocated to a mobile communication network, such as a resource allocated in 3G, 4G, 5G, 5G-A, 6G or future X-G. For example, the resource allocated to the mobile communication network (such as through frequency band combination, etc.) can also reach a very large bandwidth, which can be referred to as the first resource; a part of the resource allocated to the mobile communication network is used for non-ultra-wideband / ultra-wideband-like communication, which can be referred to as the second resource.

[0093] The bandwidth of the above-mentioned ultra-wideband is much greater than the bandwidth of the non-ultra-wideband system.

[0094] (4) The difference between the bandwidth of the first resource and the bandwidth of the second resource is greater than or equal to a bandwidth difference threshold.

[0095] The difference between the bandwidth of the first resource and the bandwidth of the second resource is greater than or equal to a bandwidth difference threshold, which means that the bandwidth of the first resource is much greater than the bandwidth of the second resource.

[0096] In the embodiments of the present disclosure, the access mechanism using the first resource is referred to as the first access mechanism, and the access mechanism using the second resource is referred to as the second access mechanism.

[0097] In some embodiments, the above-mentioned second resource can be a random access resource configured by a traditional or current system; and the second access mechanism is a traditional or current access mechanism used in the system. For example, a random access mechanism used in 3G, 4G, 5G or 5G-A, 6G or future X-G.

[0098] In some embodiments, the transmit power spectral density on the first resource satisfies at least one of the following conditions:

[0099] (A) The power spectral density of transmitting information on the first resource is less than the transmit power spectral density of transmitting information on the second resource.

[0100] (B) The difference between the power spectral density of transmitting information on the second resource and the power spectral density of transmitting information on the first resource is greater than or equal to a power spectral density difference threshold.

[0101] The difference between the power spectral density of the information transmitted on the second resource and the power spectral density of the information transmitted on the first resource is greater than or equal to a power spectral density difference threshold, which means that the difference between the power spectral density of the information transmitted on the second resource and the power spectral density of the information transmitted on the first resource is large, that is, the power spectral density of the information transmitted on the second resource is much greater than the power spectral density of the information transmitted on the first resource.

[0102] (C) The preset power spectral density threshold is determined by negotiation of the two networks participating in frequency multiplexing.

[0103] The power spectral density of the information transmitted on the first resource is less than or equal to the preset power spectral density threshold. For example, the preset power spectral density threshold can be -41.3 dBm.

[0104] The preset power spectral density threshold can be negotiated by the two networks participating in frequency multiplexing.

[0105] For example, if the uplink transmission of the terrestrial network (TN) uses the uplink frequency of the non-terrestrial network (NTN), the NTN network or the NTN network and the TN network negotiate to give a preset power spectral density threshold (PSD-threshold), and the transmit power spectral density of the uplink transmission of the TN is PSD1, which is less than the PSD-threshold. The above PSD-threshold can ensure that the uplink transmission of the TN using the uplink frequency of the NTN will not cause interference to the uplink reception of the NTN.

[0106] (D) The transmit power spectral density of the terminal sending information on the first resource is determined according to the position of the terminal, and the size of the transmit power spectral density is positively correlated with the access distance, which is the distance between the terminal and the first network device.

[0107] Optionally, different configurations can be made according to different positions of the terminal.

[0108] For example, if the uplink transmission of the TN uses the uplink frequency of the NTN, if the UE is close to the TN base station, the transmit power spectral density of the UE sending uplink data to the TN base station using the uplink frequency of the NTN can be set to be small; if the UE is far away from the TN base station, the transmit power spectral density of the UE sending uplink data to the TN using the uplink frequency of the NTN can be set to be large.

[0109] (E) determining the power spectral density of the terminal transmitting information on the first resource according to whether the second network device is within a target range, the second network device and the first network device in communication with the terminal participating in frequency multiplexing, the target range being a certain range in the uplink communication direction of the terminal to the first network device.

[0110] For example, the power spectral density can be determined according to the relationship between the satellite of the NTN and the TN base station.

[0111] FIG. 4 is a schematic diagram of a UE transmitting uplink data to a TN base station using an uplink frequency of an NTN. As shown in FIG. 4, the satellite of the NTN is in the uplink communication direction of the UE to the TN base station, or the satellite of the NTN is within a certain range in the uplink communication direction of the UE to the TN base station, and the triangle in FIG. 4 indicates the uplink communication direction of the UE to the TN base station or the certain range in the uplink communication direction.

[0112] FIG. 5 is a schematic diagram of another UE transmitting uplink data to a TN base station using an uplink frequency of an NTN. As shown in FIG. 5, the satellite of the NTN is not in the uplink communication direction of the UE to the TN base station, or the satellite of the NTN is not within a certain range in the uplink communication direction of the UE to the TN base station, and the triangle in FIG. 5 indicates the uplink communication direction of the UE to the TN base station or the certain range in the uplink communication direction.

[0113] The NTN and the TN participate in frequency multiplexing, and in the case shown in FIG. 4, a smaller power spectral density value can be used, and in the case shown in FIG. 5, a larger power spectral density value can be used.

[0114] In some embodiments, transmitting information on the first resource indicated by the first resource configuration comprises: transmitting a first message of a network access procedure on the first resource.

[0115] FIG. 6 is a schematic diagram of a flow of another message transmission method in an embodiment of the present disclosure, which can include but is not limited to the following steps:

[0116] 601. The first network device sends a first resource configuration to the terminal.

[0117] The first resource configuration is used to indicate the first resource.

[0118] 602. The terminal transmits a first message of a network access procedure on the first resource.

[0119] Correspondingly, the first network device receives the first message of the network access procedure on the first resource.

[0120] In some embodiments, the first message of the network access procedure is a first message of a non-coordinated random access technology.

[0121] In some embodiments, the terminal determines to have the capability to support the first resource based transmission information.

[0122] In some embodiments, the terminal transmits the first message of the network access procedure on the first resource when the terminal determines to have the capability to support the first resource based transmission information.

[0123] In some embodiments, the first network device further transmits a second resource configuration to the terminal, and the terminal receives the second resource configuration, where the second resource configuration indicates a second resource for transmission information.

[0124] In some embodiments, the terminal transmits the first message of the network access procedure on the first resource when a target condition is met.

[0125] The target condition includes at least one of the following:

[0126] The terminal fails to access the network using the second resource;

[0127] The terminal attempts to access the network using the second resource for a number of times greater than or equal to a first preset number of times.

[0128] In some embodiments, the first preset number of times can be configured by the network, or the first preset number of times can be predefined.

[0129] In some embodiments, the terminal can preferentially attempt to access the first network device using the second resource, and attempt to access the first network device using the first resource when the terminal fails to access the network.

[0130] In some embodiments, the terminal can attempt to access the first network device using the first resource when the terminal fails to access the first network device using the second resource for a number of times.

[0131] In some embodiments, after the terminal transmits the first message of the network access procedure on the first resource, the terminal can further perform any one of the following:

[0132] The terminal transmits the first message of the network access procedure on the second resource when the terminal fails to access the network using the first resource;

[0133] The terminal transmits the first message of the network access procedure on the second resource when the terminal attempts to access the network using the first resource for a number of times greater than or equal to a second preset number of times.

[0134] In some embodiments, the second preset number of times can be configured by the network, or the second preset number of times can be predefined.

[0135] In some embodiments, the terminal can preferentially attempt to access the first network device using the first resource, and attempt to access the first network device using the second resource when the access to the network fails. The "accessing the first network device" is understood as accessing the network in which the first network device is located, and the following description is similar, and will not be described additionally.

[0136] In some embodiments, the terminal can attempt to access the first network device using the second resource when the access to the first network device using the first resource fails multiple times.

[0137] In some embodiments, the terminal can determine to access the first network device using the first resource or the second resource based on a channel quality or a measurement result. For example, if the channel quality is good, the first resource / second resource is selected; if the channel quality is poor, the second resource / first resource is selected. The measurement result can be, for example, RSRP (Reference Signal Receiving Power) or RSRQ (Reference Signal Receiving Quality). The measurement result can reflect the channel quality. For example, if the RSRP / RSRQ is greater than a given threshold, the channel quality is defined as good; otherwise, the channel quality is defined as poor.

[0138] In some embodiments, the first message of the network access procedure is sent on the first resource, including: sending the first message of the network access procedure on the first resource when the indication information is received.

[0139] In some embodiments, the above indication information is used to indicate at least one of the following cases, including but not limited to:

[0140] Case 1: the number of terminals using the second resource is greater than a preset number.

[0141] The preset number can be set according to actual needs, and the embodiments of the present disclosure are not limited.

[0142] Case 2: the channel quality parameter of the terminal using the first resource is greater than or equal to a channel quality threshold.

[0143] Case 3: the signal quality parameter of the terminal using the first resource is less than the channel quality threshold.

[0144] Case 4: the channel quality parameter of the terminal using the second resource is greater than or equal to the channel quality threshold.

[0145] Case 5: the signal quality parameter of the terminal using the second resource is less than the channel quality threshold.

[0146] The channel quality parameter can be a reference signal receiving power (RSRP) value. The channel quality parameter can also be other parameters that can indicate reference signal quality, and the embodiments of the present disclosure are not limited in this regard.

[0147] In some embodiments, the first resource is a resource allocated to a current ultra-wideband (UWB) system frequency band.

[0148] In some embodiments, the first resource is a resource allocated to a mobile communication network. For example, a communication resource allocated to 3G, 4G, 5G, 5G-A, 6G, or future X-G.

[0149] In some embodiments, the first resource partially overlaps with the second resource.

[0150] FIG. 7 is a schematic diagram of a first resource and a second resource in an embodiment of the present disclosure. As shown in FIG. 7, the first resource and the second resource do not overlap on the UWB frequency band; but the first resource on the resource allocated to the mobile communication network partially overlaps with the second resource on the resource allocated to the mobile communication network.

[0151] In different scenarios, the definition of the above ultra-wideband and quasi-ultra-wideband is different in the embodiments of the present disclosure.

[0152] For example, in scenario 1, the frequency configuration of the Chinese ultra-wideband includes 6GHz-9GHz, and the transmission power spectral density is -41.3dBm. The Ministry of Industry and Information Technology has also explicitly divided the upper half of the 6GHz frequency band (6425-7125MHz) to the International Mobile Telecommunications (IMT). Therefore, the ultra-wideband can use all or part of the resources of 6GHz-9GHz (including the 6425-7125MHz allocated to the IMT) with a power spectral density limit of -41.3dBm.

[0153] For example, in scenario 2, the current Chinese Frequency Range 1 (FR1) allocates 34MHz of 1626.5MHz-1660.5MHz and 30MHz of 2170MHz-2200MHz to the NTN uplink frequency. Therefore, the quasi-ultra-wideband can use the above 34MHz of resources through frequency spreading, and realize frequency multiplexing through code division, which can configure more random access resources. The FR1 is the main frequency band of 5G, because the frequency range of this frequency band is from 450MHz to 6000MHz, the frequency is low, the penetration ability is strong, and the coverage effect is good.

[0154] In the embodiments of the present disclosure, after the terminal accesses the first network device through the super wideband mode (the first resource), the terminal can also receive and send subsequent information based on the super wideband mode (the first resource).

[0155] In some embodiments, the message is received or sent on the first resource indicated by the first resource configuration, including any one of the following:

[0156] The second message of the random access procedure is received on the first resource;

[0157] The third message of the random access procedure is sent on the first resource;

[0158] The fourth message of the random access procedure is received on the first resource.

[0159] For example, the second message of the random access procedure described above can be a random access response (RAR).

[0160] For example, the third message of the random access procedure described above can be a random access message 3 (Msg3).

[0161] For example, the fourth message of the random access procedure described above can be a random access message 4 (Msg4).

[0162] In some embodiments, the second message of the random access procedure includes at least one of the following information:

[0163] The indication information of the sending mode of the third message of the random access procedure;

[0164] The indication information of the receiving mode of the fourth message of the random access procedure.

[0165] For example, it can be indicated in the RAR whether to send the third message of the random access procedure in the super wideband mode (i.e. the first resource).

[0166] For example, it can be indicated in the RAR whether to receive the fourth message of the random access procedure in the super wideband mode (i.e. the first resource).

[0167] In some embodiments, the third message of the random access procedure includes the indication information of the receiving mode of the fourth message of the random access procedure requested by the terminal to receive.

[0168] For example, it is indicated in the Msg3 that the terminal hopes or requests to receive the fourth message of the random access procedure in the super wideband mode (i.e. the first resource).

[0169] It should be noted that the first resource refers to a resource such as ultra-wideband or ultra-wideband-like, and the receiving of the second message of the random access procedure on the first resource, the sending of the third message of the random access procedure on the first resource, and the receiving of the fourth message of the random access procedure on the first resource can be message exchanges using different resources in such resources.

[0170] FIG. 8 is a flow diagram of another message exchange method in an embodiment of the present disclosure, which can include but is not limited to the following steps:

[0171] 801. The first network device sends an ultra-wideband access configuration to the terminal.

[0172] The ultra-wideband access configuration can be a first resource configuration for indicating the first resource.

[0173] 802. The terminal determines to support access in an ultra-wideband manner.

[0174] 803. The terminal selects to initiate access in an ultra-wideband manner.

[0175] The ultra-wideband manner refers to a manner of accessing the first resource.

[0176] 804. The terminal sends Msg3 to the first network device in an ultra-wideband manner.

[0177] The sending of Msg3 can refer to the sending of the third message of the random access procedure.

[0178] 805. The first network device sends Msg4 to the terminal.

[0179] The sending of Msg3 can refer to the sending of the fourth message of the random access procedure.

[0180] In some embodiments, the first resource uses pulse modulation for data transmission. Alternatively, the first resource uses spread spectrum for data transmission. The spread spectrum can be, for example, direct sequence spread spectrum, time hopping spread spectrum, or frequency hopping spread spectrum, or a combination of the above spread spectrum techniques.

[0181] In some embodiments, the first resource can also use a multi-band UWB manner for data transmission.

[0182] In some embodiments, the first network device can send a resource indication to the terminal, and the terminal can receive the resource indication sent by the first network device, and the resource indication is used to indicate that the terminal supports transmission based on the first resource transmission information.

[0183] In some embodiments, the first network device may send indication information to indicate whether the first network device supports or allows the terminal to use the first access mechanism (i.e., the mechanism for network access using the first resource).

[0184] In some embodiments, the first network device may implicitly indicate that it supports or allows the terminal to use the first access mechanism by sending a first access resource configuration.

[0185] In some embodiments, the terminal may also send any of the following types of information to the first network device:

[0186] The terminal supports contention-based random access based on the first resource;

[0187] The terminal supports non-contention-based random access based on the first resource;

[0188] The terminal supports the ability to transmit information based on the first resource.

[0189] Accordingly, the first network device receives any of the above information sent by the terminal so that the first network device can determine whether it can configure the terminal with non-contention random access resources based on ultra-wideband (i.e., based on the first resource). If the first network device has already used the ultra-wideband-based random access mechanism when accessing the network, then the first network device can assume that the terminal supports the ultra-wideband-based non-contention random access mechanism.

[0190] In some embodiments, when the network device providing services to the terminal is switched from a first network device to a third network device, the terminal may send a capability indication to the third network device.

[0191] The capability indicator is used to indicate that the terminal supports the ability to transmit information based on the first resource.

[0192] In some embodiments, when the network device providing services to the terminal is switched from a first network device to a third network device, the terminal sends a request message to the third network device.

[0193] This request message is used to request any of the following resources:

[0194] Resources are accessed randomly based on competition for the first resource.

[0195] Resources are accessed randomly without contention based on the first resource.

[0196] In some embodiments, the terminal may request a third network device to allocate non-contention-based or contention-based random access resources based on ultra-wideband (UWB). Optionally, the third network device allocates non-contention-based or contention-based random access resources based on UWB to the terminal.

[0197] In some embodiments, the network devices can interact with each other to support the capability of the ultra-wideband access mechanism, for example, the first network device and the third network device can interact with each other to support the capability of the ultra-wideband access mechanism.

[0198] In some embodiments, the first resource configuration is received, including: when the terminal is handed over from the first network device to the third network device by the service network device of the terminal, receiving the first resource information sent by the third network device;

[0199] The first resource configuration is used to indicate any one of the following resources:

[0200] The resource based on the first resource of the contention random access;

[0201] The resource based on the first resource of the non-contention random access.

[0202] When the network device providing service for the terminal is handed over from the first network device to the third network device, the terminal sends a capability indication to the third network device, and after the third network device receives the capability indication, the third network device sends the first resource information to the terminal.

[0203] The capability indication is used to indicate that the terminal supports the capability based on the first resource transmission information.

[0204] When the network device providing service for the terminal is handed over from the first network device to the third network device, the terminal sends a request message to the third network device, and after the third network device receives the request message, the first resource information can be sent to the terminal.

[0205] The request message is used to request any one of the following resources:

[0206] The resource based on the first resource of the contention random access;

[0207] The resource based on the first resource of the non-contention random access.

[0208] In some embodiments, the ultra-wideband mode can exist but is not limited to the following two modes:

[0209] Short-distance communication mode: similar to the current UWB communication mode, 10 meters or shorter distance;

[0210] Long-distance communication mode: such as used in mobile communication network, the communication distance reaches hundreds of meters.

[0211] For a terminal supporting short-distance communication mode, the terminal can be configured to use the ultra-wideband mode for short-distance communication mode or for long-distance communication mode.

[0212] There are some differences between the short-range communication mode and the long-range communication mode, such as different channel models, the terminal may need to do some different processing; for example, the data link layer may be different, the short-range communication mode is one data link layer, and the long-range communication mode is another data link layer.

[0213] In some embodiments, the communication mode can be distinguished according to different application scenarios. For example, if the terminal is applied in a massive access scenario, the ultra-wideband mode used by the terminal is configured as the long-range communication mode.

[0214] In the embodiments of the present disclosure, the provided access mechanism based on ultra-wideband does not use the resources allocated to the mobile communication network (uses the resources allocated to the UWB system) or uses the resources allocated to the mobile communication network (does not use the resources allocated to the UWB system), so that the bandwidth of the used resources is large enough and / or the transmit power spectral density of the information transmitted on the used resources is small enough, thereby improving the resource utilization efficiency. For example, even if the first resource overlaps or partially overlaps with the relatively small resource (such as a random access resource, a data transmission resource, etc.) defined by the mobile communication network, the first resource can still be used for random access or other data transmission.

[0215] It should be understood that, although each step in the flowchart involved in each of the above embodiments is displayed in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each of the above embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.
