[0047] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled 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 "including" and "having" and any variations thereof in the specification and claims of the present disclosure and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0049] In the description of the embodiments of the present disclosure, technical terms such as "first" and "second" are used solely to distinguish between different objects and should not be understood to indicate or imply relative importance or to implicitly specify the quantity, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of the present disclosure, "plurality" means more than two, unless otherwise specifically defined.

[0050] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] In the description of the embodiments of the present disclosure, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0052] Multiple international organizations are researching new wireless communication systems (6G). The main driving force behind this is the growth in the number of access terminals, which are mainly machine-type devices. The terminal density in terms of key technical indicators can reach tens of millions of terminals per square kilometer.

[0053] The initial access and data transmission of a massive number of terminals is limited by network coordination signaling and data transmission resources. Conventional contention-based access technologies cannot accommodate such a large number of terminals. Furthermore, each random access resource occupies one physical resource block (PRB). This large number of terminals requires tens of thousands or more PRBs, far exceeding the total number of PRBs in the system. Furthermore, traditional random access resources are used only for random access. Even if no terminal uses the resource for random access, it cannot be used for data transmission, consuming significant system resources and inefficiently.

[0054] Ultra-wideband (UWB) is a technology that transmits low-power density signals across a large bandwidth to achieve communication. It is defined as an absolute bandwidth of at least 500 MHz or a relative bandwidth of at least 20% at an amplitude attenuation of -10 dB (this definition was adopted by the FCC in February 2002 when it approved UWB technology for civilian use). The goal of UWB is to achieve frequency reuse by transmitting signals over an extremely wide bandwidth with a low transmit power spectral density (no greater than -41.3 dBm), which may be allocated to other systems.

[0055] The Federal Communications Commission (FCC) of the United States stipulates that UWB technology can transmit signals within the 3.1GHz to 10.6GHz bandwidth, with a transmit power spectral density no higher than -41.3dBm. The 3.1GHz to 10.6GHz band includes frequencies used for satellite communications, as well as the Unlicensed National Information Infrastructure (U-NII) and industrial, scientific, and medical bands. When using these frequency bands, UWB must not interfere with the normal communications of existing communication systems within the bands, nor require these communication systems to make any coordination or concessions for UWB use. Therefore, the transmit power spectral density of UWB in these bands must not exceed -41.3dBm.

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

[0057] Table 1

[0058]

[0059] As shown in Table 1 above, according to current Chinese regulations, the frequency band potentially applicable to UWB is 6 GHz to 9 GHz. Other frequency bands can also use UWB technology, but the power spectral density is lower and the transmit power is more restricted. The Ministry of Industry and Information Technology's 2023 update to the "Regulations on Radio Management of Ultra-Wideband (UWB) Equipment" updated the UWB spectrum to 7235-8750 MHz.

[0060] At present, UWB implementation technologies mainly include two categories:

[0061] Pulse-based UWB: This method transmits data by sending extremely narrow pulses (e.g., 0.2ns-1.5ns). Because the pulse width is so narrow, the signal bandwidth is very wide. The modulation method is pulse modulation, which directly transmits information by modulating the pulse width, amplitude, position, or presence / absence.

[0062] Multi-Band OFDM UWB (MB-OFDM UWB): This technology divides the frequency domain resources allocated for UWB into multiple band groups. Each band group contains multiple subbands, each with a bandwidth of 528 MHz. In actual use, a time-frequency code (TFC) controls which subband to use for data transmission.

[0063] Figure 1 shows a schematic diagram of subband division for multi-band UWB. This subband division diagram divides frequencies into multiple band groups along the horizontal axis (frequency (f)). The vertical axis in Figure 1 is meaningless. These band groups are Band Group #1, Band Group #2, Band Group #3, Band Group #4, and Band Group #5 in Figure 1. Each of these band groups includes two or three subbands. As shown in Figure 1, the total subbands included are: 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] Figure 2 shows a schematic diagram of subband usage in a multi-band UWB system. In Figure 2, the first transmission uses band 1, the second transmission uses band 2, and the third transmission uses band 3. Band 1, band 2, and band 3 are different subbands. IFFT in Figure 2 stands for Inverse Fast Fourier Transform, and OFDM stands for Orthogonal Frequency Division Multiplexing.

[0065] To meet the massive access demands of 6G, currently proposed technologies include uncoordinated random access, which eliminates most coordination between terminals and the network and can support scenarios with massive numbers of terminals. While this improves resource efficiency compared to traditional random access mechanisms, it still uses the frequency resources of the mobile communication network, and the resources allocated to uncoordinated random access can only be used for random access.

[0066] In the disclosed embodiments, reference is made to UWB technology to implement an ultra-wideband (UWB)-based access mechanism in a mobile communication network. This mechanism allocates UWB resources for random access, enabling the coexistence of UWB-based random access and traditional random access methods. Of course, the UWB resources allocated in the mobile communication network can also be used for data and signaling transmission, such as subsequent signaling, channel, signal, or data transmission after network access is completed.

[0067] In the message sending and receiving method of the embodiment of the present disclosure, the terminal can receive a 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 spectrum density of the information transmitted on the first resource is less than or equal to a preset power spectrum density threshold. Through this solution, the bandwidth of the first resource is large enough, and the power spectrum density when transmitting information on the first resource is small enough, thereby improving resource utilization efficiency. For example, even if the first resource overlaps or partially overlaps with a resource with a relatively small bandwidth defined by the mobile communication network (such as a random access resource, a data transmission resource, etc.), 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 may be an access network device, such as a base station, an evolved base station (eNB), a base station in a 5G, 6G, or future XG network, or a satellite. In the term "XG," "X" may be 7, 8, or more, indicating the generation of evolution or iteration of the communication system. For example, the future may have 7th-generation and 8th-generation communication systems. The following description is similar and will not be further explained.

[0069] In the embodiments of the present disclosure, a terminal may be a user equipment (UE), which is also referred to as a terminal device. For example, the terminal may 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 one type of resource, and the second resource refers to another type of resource.

[0071] FIG3 is a flow chart of a message sending and receiving method provided by an embodiment of the present disclosure, which includes but is not limited to the following steps:

[0072] 301. A first network device sends a first resource configuration to a 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 a first resource indicated by a first resource configuration.

[0076] Accordingly, 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 spectrum density of information transmitted on the first resource is less than or equal to a preset power spectrum density threshold.

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

[0079] In some embodiments, the message sending and receiving method in the embodiments of the present disclosure further includes: the terminal determining that it has the capability to support information transmission based on the first resource.

[0080] In some embodiments, when the terminal determines that it has the capability to support information transmission 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, which may include but is not limited to: the terminal receives information on the first resource indicated by the first resource configuration, or the terminal sends 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 the preset power spectral density threshold, which may include but is not limited to: the power spectral density of the information received on the first resource is less than or equal to the preset power spectral density threshold, or the transmission power spectral density of the information sent on the first resource is less than or equal to the 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 -10dB absolute bandwidth 500MHz, that is, the first bandwidth threshold is -10dB absolute bandwidth 500MHz. For example, such resources are called ultra-wideband resources.

[0086] It should be noted that the first bandwidth threshold can also be set to a -10dB absolute bandwidth of 400MHz or greater, or a -10dB absolute bandwidth of 300MHz or greater. For example, such resources can be referred to as quasi-ultra-wideband resources. The first bandwidth threshold can also be set based on actual needs and is not limited in the present embodiment.

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

[0088] Exemplarily, 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 may also be set to 15%, 18%, etc. The second bandwidth threshold may also be set according to actual needs, which is not limited in the embodiment of the present disclosure.

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

[0091] In some embodiments, the first resource may be an ultra-wideband-based or ultra-wideband-like resource; the second resource may be a non-ultra-wideband-based resource, or a non-ultra-wideband-like resource.

[0092] The aforementioned ultra-wideband resources can be resources currently allocated to UWB systems, such as the 3.1 GHz to 10.6 GHz band allocated by the United States. They can also be resources allocated to mobile communication networks, such as those allocated for 3G, 4G, 5G, 5G-A, 6G, or future XG. For example, resources allocated to mobile communication networks (e.g., through frequency band combination) can also achieve a large bandwidth and can be referred to as first resources. When a portion of the resources of the mobile communication network are allocated for non-ultra-wideband / non-ultra-wideband-based communications, such resources can be referred to as second resources.

[0093] The bandwidth of the above-mentioned ultra-wideband system is much larger than that 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 the 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 the bandwidth difference threshold, indicating that the bandwidth of the first resource is significantly different from the bandwidth of the second resource, that is, the bandwidth of the first resource is much greater than the bandwidth of the second resource.

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

[0097] In some embodiments, the second resource may be a conventional random access resource or a random access resource that can be configured in a current system; and the second access mechanism may be a conventional access mechanism used in a current system, such as a random access mechanism used in 3G, 4G, 5G or 5G-A, 6G, or future XG.

[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 information transmitted on the first resource is less than the transmission power spectral density of information transmitted on the second resource.

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

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

[0102] (C) The preset power spectrum density threshold is determined by negotiation between the two networks participating in frequency reuse.

[0103] The power spectrum density of the information transmitted on the first resource is less than or equal to a preset power spectrum density threshold. Exemplarily, the preset power spectrum density threshold may be -41.3 dBm.

[0104] The preset power spectrum density threshold may be negotiated by two networks participating in frequency reuse.

[0105] For example, if the uplink transmission of a terrestrial network (TN) uses the uplink frequency of a non-terrestrial network (NTN), the NTN or the NTN and TN networks negotiate to provide a preset power spectrum density threshold (PSD-threshold). The transmit power spectrum density of the TN uplink transmission is PSD1, and PSD1 is less than the PSD-threshold. The above PSD-threshold can ensure that when the TN uplink transmission uses the NTN uplink frequency, it will not interfere with the NTN uplink reception.

[0106] (D) Determine, based on the location of the terminal, a transmit power spectrum density for sending information by the terminal on the first resource, where the transmit power spectrum 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 the location of the terminal.

[0108] For example, taking the uplink transmission of TN using the uplink frequency of NTN as an example, if the UE is close to the TN base station, then when the UE uses the uplink frequency of NTN to send uplink data to the TN base station, the transmission power spectrum density can be set to be smaller; if the UE is far away from the TN base station, when the UE uses the uplink frequency of NTN to send uplink data to TN, the transmission power spectrum density can be set to be larger.

[0109] (E) Determine a power spectral density of information transmitted by the terminal on the first resource based on whether the second network device is within a target range. The second network device and the first network device communicating with the terminal participate in frequency reuse. The target range is a certain range in the uplink communication direction of the terminal to the first network device.

[0110] Exemplarily, the power spectrum density value may be determined according to the relationship between the NTN satellite and the TN base station.

[0111] Figure 4 is a schematic diagram of a UE transmitting uplink data to a TN base station using an NTN uplink frequency. As shown in Figure 4 , the NTN satellite is in the direction of communication from the UE to the TN base station, or within a certain range of the direction of communication from the UE to the TN base station. The triangles in Figure 4 indicate the direction of communication from the UE to the TN base station or within a certain range of the direction of communication.

[0112] Figure 5 shows another example of a UE transmitting uplink data to a TN base station using the NTN uplink frequency. As shown in Figure 5, the NTN satellite is not in the direction of communication from the UE to the TN base station, or the NTN satellite is not within a certain range of the direction of communication from the UE to the TN base station. The triangles in Figure 5 indicate the direction of communication from the UE to the TN base station or within a certain range of the direction of communication.

[0113] NTN and TN participate in frequency reuse. In the case shown in FIG4 , a smaller power spectrum density value can be used; in the case shown in FIG5 , a larger power spectrum density value can be used.

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

[0115] FIG6 is a flow chart of another method for sending and receiving messages according to an embodiment of the present disclosure. The method may include but is not limited to the following steps:

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

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

[0118] 602. The terminal sends a first message of a network access process on a first resource.

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

[0120] In some embodiments, the first message of the network access process is a first message of an uncoordinated random access technology.

[0121] In some embodiments, the embodiments of the present disclosure also include: the terminal determines that it has the capability to support information transmission based on the first resource.

[0122] In some embodiments, when the terminal determines that it has the capability to support information transmission based on the first resource, a first message of the network access procedure is sent on the first resource.

[0123] In some embodiments, the embodiments of the present disclosure also include: the first network device sends a second resource configuration to the terminal, and accordingly, the terminal receives the second resource configuration; wherein the second resource configuration indicates a second resource for transmitting information.

[0124] In some embodiments, sending a first message of a network access procedure on a first resource includes: sending a first message of a network access procedure on the first resource when a target condition is met;

[0125] The above target conditions include at least one of the following:

[0126] Failure to access the network using the second resource;

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

[0128] In some embodiments, the first preset number may be network configured, or the first preset number may be predefined.

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

[0130] In some embodiments, the terminal may try to access the first network device using the first resource after failing to access the first network device using the second resource multiple times.

[0131] In some embodiments, after sending the first message of the network access process on the first resource, the terminal may further perform any of the following:

[0132] When accessing the network using the first resource fails, sending a first message of the network access process on the second resource;

[0133] When the number of attempts to access the network using the first resource is greater than or equal to a second preset number, a first message of the network access process is sent on the second resource.

[0134] In some embodiments, the second preset number may be network configured, or the second preset number may be predefined.

[0135] In some embodiments, the terminal may preferentially attempt to access the first network device using the first resource, and if network access fails, attempt to access the first network device using the second resource. "Accessing the first network device" is understood to mean accessing the network where the first network device resides. The following description is similar and will not be further explained.

[0136] In some embodiments, if the terminal fails to access the first network device using the first resource multiple times, the terminal may try to access the first network device using the second resource.

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

[0138] In some embodiments, sending a first message of a network access process on a first resource includes: sending the first message of a network access process on the first resource when indication information is received.

[0139] In some embodiments, the above indication information is used to indicate at least one of the following situations, 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 is not limited in the embodiment of the present disclosure.

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

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

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

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

[0146] The channel quality parameter may be a reference signal received power (RSRP) value. The channel quality parameter may also be other parameters that can indicate the quality of a reference signal, which is not limited in the embodiments of the present disclosure.

[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, illustratively, a communication resource allocated to 3G, 4G, 5G, 5G-A, 6G, or future XG.

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

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

[0151] In the embodiments of the present disclosure, in different scenarios, the definitions of the ultra-bandwidth and quasi-ultra-bandwidth are different.

[0152] For example, in scenario 1, China's ultra-wideband frequency configuration includes 6GHz-9GHz, using a transmit power spectral density of -41.3dBm. The Ministry of Industry and Information Technology has issued a new version of the "Radio Frequency Allocation Regulations of the People's Republic of China," which explicitly allocates the upper half of the 6GHz band, 6425-7125MHz, to the International Mobile Telecommunications (IMT) system. Therefore, ultra-wideband can use all or part of the 6GHz-9GHz band (including the 6425-7125MHz allocated to IMT) with a power spectral density of -41.3dBm.

[0153] For example, in Scenario 2, China currently allocates 34 MHz of uplink frequencies to NTN in Frequency Range 1 (FR1), ranging from 1626.5 MHz to 1660.5 MHz, and 30 MHz from 2170 MHz to 2200 MHz. Ultra-wideband (UWB) can utilize the aforementioned 34 MHz resources through spread spectrum, achieve frequency reuse through code division, and configure more random access resources. FR1 is the primary frequency band for 5G, as it ranges from 450 MHz to 6000 MHz, offers low frequencies, strong penetration, and excellent coverage.

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

[0155] In some embodiments, sending and receiving a message on the first resource indicated by the first resource configuration includes any of the following:

[0156] receiving a second message of a random access procedure on the first resource;

[0157] Sending a third message of the random access procedure on the first resource;

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

[0159] Exemplarily, the second message of the random access process may be a random access response (Random access response, RAR).

[0160] Exemplarily, the third message of the random access process may be random access message 3 (Random Access Message 3, Msg3).

[0161] Exemplarily, the fourth message of the random access process may be random access message 4 (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] Indication information of a sending method of the third message of the random access procedure;

[0164] Indication information of a reception method of the fourth message of the random access procedure.

[0165] Exemplarily, it may be indicated in the RAR whether the third message of the random access procedure is sent in an ultra-wideband manner (ie, the first resource).

[0166] Exemplarily, it may be indicated in the RAR whether the fourth message of the random access procedure is received in an ultra-wideband manner (ie, the first resource).

[0167] In some embodiments, the third message of the random access procedure includes: indication information of a receiving manner in which the terminal requests to receive the fourth message of the random access procedure.

[0168] Exemplarily, Msg3 indicates that the terminal wishes to or requests to receive the fourth message of the random access procedure in an ultra-wideband manner (ie, the first resource).

[0169] It should be noted that the above-mentioned first resource refers to ultra-wideband or ultra-wideband-like resources. When the second message of the random access process is received on the first resource, the third message of the random access process is sent on the first resource, and the fourth message of the random access process is received on the first resource, different resources in this type of resources can be used to send and receive messages.

[0170] FIG8 is a flow chart of another method for sending and receiving messages according to an embodiment of the present disclosure. The method may include but is not limited to the following steps:

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

[0172] The ultra-wideband access configuration may be a first resource configuration, used to indicate a first resource.

[0173] 802. The terminal determines that it supports access in ultra-wideband mode.

[0174] 803. The terminal chooses to initiate access in ultra-wideband mode.

[0175] The ultra-bandwidth method refers to a method of accessing using the first resource.

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

[0177] The sending of Msg3 may refer to sending the third message of the random access process.

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

[0179] The sending of Msg3 may refer to sending the fourth message of the random access process.

[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 method may include direct sequence spread spectrum, time hopping spread spectrum, frequency hopping spread spectrum, or a combination of the above spread spectrum technologies.

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

[0182] In some embodiments, the first network device may send a resource indication to the terminal. Correspondingly, the terminal may receive the resource indication sent by the first network device, where the resource indication is used to indicate that the terminal is supported to transmit information based on the first resource.

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

[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 the first access resource configuration.

[0185] In some embodiments, the terminal may further send any of the following 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 random access based on the first resource;

[0188] The terminal supports a capability of transmitting information based on the first resource.

[0189] Correspondingly, 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 a non-competitive random access resource based on ultra-wideband (i.e., based on the first resource) for the terminal. If the ultra-wideband-based random access mechanism has been used when the first network device accesses, then the first network device can consider that the terminal supports the ultra-wideband-based non-competitive random access mechanism.

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

[0191] The capability indication is used to indicate the capability of the terminal to support information transmission based on the first resource.

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

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

[0194] A resource for random access based on contention for a first resource;

[0195] A resource for non-contention random access based on the first resource.

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

[0197] In some embodiments, network devices may interact with each other to determine whether they support capabilities based on an ultra-wideband access mechanism. For example, the first network device and the third network device may interact with each other to determine whether they support capabilities based on an ultra-wideband access mechanism.

[0198] In some embodiments, receiving the first resource configuration includes: when the serving network device of the terminal is switched from the first network device to the third network device, receiving first resource information sent by the third network device;

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

[0200] A resource for random access based on contention for a first resource;

[0201] A resource for non-contention random access based on the first resource.

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

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

[0204] When the network device providing service for the terminal is switched from the first network device to the third network device, the terminal sends a request message to the third network device. After receiving the request message, the third network device may send the first resource information to the terminal.

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

[0206] A resource for random access based on contention for the first resource;

[0207] Resources for non-contention random access based on the first resources.

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

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

[0210] Long-distance communication mode: For example, it is used in mobile communication networks, with a communication distance of several hundred meters.

[0211] For a terminal that supports the short-range communication mode, the terminal can be configured to use the ultra-wideband method as the short-range communication mode or the long-range communication mode.

[0212] There are some differences between short-distance communication mode and long-distance communication mode. For example, the channel model is different, and the terminal may need to do some different processing. For example, the data link layer may be different. The short-distance communication mode uses one data link layer, and the long-distance communication mode uses another data link layer.

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

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

[0215] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0216] Based on the same technical concept, the embodiments of the present disclosure further provide a communication device that can implement the functions of the terminal or the first network device in the aforementioned embodiments.
