[0032] The present application will be described in more detail below with reference to the drawings and embodiments.

[0033] In the heterogeneous network construction shown in Figure 1, as shown in Figure 2, after the terminal is activated, a series of processes such as synchronization and random access are performed via radio frequency uplink and downlink. First, the terminal accesses a radio frequency base station, then the terminal measures the synchronization signal or reference signal quality of all receivable visible light base stations, reports the measurement results to the radio frequency base station via the radio frequency uplink, and the radio frequency base station selects the highest quality visible light base station and adds it through Radio Resource Control (RRC) reconfiguration. Here, considering that there is no visible light uplink in the heterogeneous network construction system, the terminal does not need to communicate directly with the visible light base station and perform uplink synchronization via the random access process.

[0034] However, as can be seen from the process shown in Figure 2, in the initial access process of building a visible light heterogeneous network, if a terminal wants to access a visible light base station, it must first access a radio frequency base station, report all measured visible light downlink quality to the radio frequency base station, and then add an appropriate visible light base station via the radio frequency base station to communicate. This process is relatively time-consuming. Therefore, as shown in Figure 3, the terminal can select and directly access a visible light downlink during the radio frequency access phase. In this way, the measurement reporting and radio frequency base station reconfiguration processes are omitted, thereby reducing initial access delay and improving the access process rate.

[0035] In the initial access process of building heterogeneous networks, there is currently no effective solution for how terminals receive synchronization signals / physical broadcast channel blocks (SSB: SS (Synchronized Signal) / PBCH (Physical Broadcast Channel) Block) transmitted from radio frequency downlinks and visible light downlinks, and how they select the corresponding physical random access channel (PRACH: Physical Random Access Channel) transmission resources so that radio frequency base stations can not only identify the visible light base station that the terminal is trying to access, but also receive it with the optimal uplink beam.

[0036] In view of this, in various embodiments of the present invention, the first access network device transmits information to a terminal so that the terminal can establish a mapping relationship between the second random access resource, the second signal of the second system (which may also be called a synchronization signal), and the first signal of the first system (which may also be called a synchronization signal). This enables the terminal to select the second random access resource and the optimal transmit beam and transmit the corresponding random access request information. In this way, the first access network device can identify the second access network device that the terminal intends to access and receive it with the optimal uplink beam, thereby reducing initial access delay and improving the access process rate.

[0037] An embodiment of the present invention provides a method for transmitting resources performed by a terminal, which includes the following steps, as shown in Figure 4.

[0038] In step 401, the first access network device receives the first information transmitted from the first access network device, and the first access network device can provide the terminal with access in the first manner, and the first information is Second information indicating the relationship between the first signal of the first method and the second signal of the second method, wherein the second access network device can provide access of the second method to the terminal, and the first method is different from the second method in terms of the second information. Configuration information for the second type of random access resource, Third information showing the relationship between the random access resource of the second method and the second signal of the second method, It includes at least one of the following: a second type of random access sequence (preamble) format.

[0039] In step 402, based on the first information, the first random access resource mapped by the second signal of the second method and the corresponding transmit beam are determined, and random access request information of the second method is transmitted to the first access network device.

[0040] In practical applications, the aforementioned terminal is also referred to as User Equipment (UE), terminal device, device, or user.

[0041] A heterogeneous network is formed by the first access network device and the second access network device. The first access network device is also called the master node (MN), and correspondingly, the second access network device is also called the secondary node (SN).

[0042] In one embodiment, the first access method includes radio frequency access.

[0043] In one embodiment, the second access method includes optical communication access, specifically VLC access (also called visible light access), that is, the first access network equipment can provide radio frequency access to the terminal, and the second access network equipment can provide VLC access to the terminal, and accordingly, the first access network equipment may include a radio frequency access point (AP: Access Point) (also called a radio frequency base station), and the second access network equipment may include an RLC (Radio Link Control) AP (also called a visible light base station).

[0044] Here, the terminal can receive data and control information transmitted from the first access network device via the radio frequency downlink. Correspondingly, the terminal can transmit data and / or data feedback information (i.e., Hybrid automatic retransmission request (HARQ)-ACK (ACKnowledgment) information) via the radio frequency uplink. In this case, the terminal is in a heterogeneous network consisting of VLC and radio frequency. In this heterogeneous network, heterogeneous network construction refers to a VLC downlink (also called a visible light downlink) and a radio frequency uplink, the radio frequency downlink of which can be turned on on demand.

[0045] The relationship between the first signal of the first method and the second signal of the second method is also called the mapping relationship between the first signal of the first method and the second signal of the second method, and refers to which coverage range of the second signal of the second method falls within the coverage range of the first signal of the first method. For example, in a heterogeneous network consisting of VLC and radio frequencies, the relationship between the first signal of the first method and the second signal of the second method refers to which coverage range of visible light SSB falls within the coverage range of radio frequency SSB.

[0046] In actual applications, if one second signal of a second method can correspond to at least two first signals of a first method, then, in order to save signaling overhead, in the association relationship indicated by the second information, one second signal of a second method corresponds to only one first signal of a first method.

[0047] The configuration information for the second type of random access resource may include the second type of PRACH transmission opportunity (abbreviated as RO). In actual applications, the ROs of the second type and the ROs of the first type may be independent (i.e., the ROs of the two types are different) or they may not be independent (i.e., the ROs of the two types are the same). If the ROs of the second type are the same as those of the ROs of the first type, the configuration information for the second type of random access resource can be set as the default to save signaling overhead, indicating that the configuration information for the second type of random access resource is the same as the configuration information for the first type of random access resource by default.

[0048] The association relationship between the random access resources of the second method and the second signal of the second method refers to the number of second signals of the second method associated with each random access resource of the second method. For example, in a heterogeneous network consisting of VLC and radio frequencies, the association relationship between the random access resources of the second method and the second signal of the second method refers to the number of visible light SSBs associated with each visible light RO. For example, suppose there are four ROs, RO1, RO2, RO3, and RO4, and the association relationship between the second random access resources and the second signals of the second method indicates that one visible light SSB (referred to as a reference signal (RS) for simplicity) is associated with each visible light RO, then RS1 is mapped to RO1, RS2 is mapped to RO2, RS3 is mapped to RO3, and RS4 is mapped to RO4. If the association relationship between the second random access resources and the second signals of the second method indicates that two RSs are associated with each visible light RO, then RS1 and RS2 are mapped to RO1, RS3 and RS4 are mapped to RO2, RS1 and RS2 are mapped to RO3, and RS3 and RS4 are mapped to RO4, where the second random access resources can be mapped in a default order. Herein, in actual applications, the number of second signals associated with each second random access resource may be the same as or different from the number of first signals associated with each first random access resource. If the number of second signals associated with each second-mode random access resource is the same as the number of first signals associated with each first-mode random access resource, the configuration of the association relationship between the second-mode random access resources and the second signals of the second-mode can be left as default to save signaling overhead, which means that the number of second signals associated with each second-mode random access resource is the same as the number of first signals associated with each first-mode random access resource by default.

[0049] The random access sequence format of the second method may be the same as or different from the random access sequence format of the first method. Here, if the ROs of the first method and the ROs of the second method are independent, it becomes possible to distinguish between the first and second methods through different ROs, so that the same random access sequence format can be configured for both the first and second methods. In this case, in order to reduce signaling overhead, the configuration of the random access sequence format of the second method can be made the default, indicating that the random access sequence of the second method is the same as the random access sequence of the first method by default.

[0050] In practical applications, the first information can be carried in a system message, and exemplary, in a heterogeneous network consisting of VLC and radio frequency, the terminal receives the remaining minimal system message (i.e., SIB1) via the radio frequency downlink after demodulating the radio frequency downlink physical broadcast channel (PBCH), and obtains configuration information for radio frequency random access parameters and configuration information for visible light random access parameters (i.e., the first information). Here, the configuration information for the RF random access parameters is consistent with 5G NR and includes the random access sequence format, PRACH transmission opportunity, and the association relationship between random access resources and SSB.

[0051] In actual application, in order to maintain backward compatibility, the first access network device may additionally instruct the terminal whether or not to allow access using the second method.

[0052] Based on this, one implementation example, the method, This may further include transmitting a fourth piece of information to the terminal, which indicates whether or not to allow access in the second manner.

[0053] In actual applications, the aforementioned fourth piece of information may be transmitted to the PBCH.

[0054] If the fourth piece of information instructs the terminal to allow access in the second method, the terminal performs step 402.

[0055] For example, in a heterogeneous network consisting of VLC and radio frequencies, compared to a conventional 5G nu-radio (NR) system, the content carried in SSB transmitted from a radio frequency AP needs to additionally indicate whether the radio frequency AP allows access from a visible light base station. Specifically, one bit can be set in the idle "spare" field of the 5G NR PBCH. If this bit is set to 1, it indicates that the radio frequency AP allows access from the visible light AP, and if it is set to 0, it indicates that the radio frequency AP does not allow access from the visible light AP.

[0056] In actual application, in step 402, the terminal determines whether to perform initial access using the second method based on the signal quality and first information of the second signal of at least one received second access network device. Specifically, if the signal quality of all second signals (e.g., reference signal received power (RSRP)) is less than a first threshold (which can be set as needed), the terminal directly performs the random access process using the first method based on the random access parameter configuration information. If the signal quality of at least one second signal is greater than or equal to the first threshold, the terminal can improve the success rate of access by performing initial access using the second method based on the second signal with the best signal quality.

[0057] Here, after determining the optimal second signal, the terminal determines, based on the first information, the first random access resource mapped by the second signal of the second method (i.e., the random access resource corresponding to the second signal with the best signal quality) and the corresponding transmit beam, and transmits the random access request information of the second method to the first access network equipment.

[0058] Specifically, the terminal establishes a mapping relationship between the random access resource of the second method, the second signal of the second method, and the first signal of the first method based on the first information, and then determines the first random access resource mapped by the second signal of the second method and the corresponding transmit beam based on the mapping relationship.

[0059] Here, when establishing a mapping relationship, there are two possible embodiments.

[0060] In the first method, mapping of a first mapping relationship and a second mapping relationship is performed sequentially based on the first information to obtain a mapping result, the first mapping relationship is determined based on the configuration information of the random access resource of the second method and the third information, the first mapping relationship includes a mapping relationship between the second signal of the second method and the random access resource of the second method, the second mapping relationship is determined based on the second information, the second mapping relationship includes a mapping relationship between the second signal of the second method and the first signal of the first method, and accordingly, the first random access resource and the corresponding transmit beam are determined based on the mapping result.

[0061] In the second method, mapping of the second mapping relationship and the first mapping relationship is performed sequentially based on the first information to obtain a mapping result, the first mapping relationship is determined based on the configuration information of the random access resource of the second method and the third information, the first mapping relationship includes a mapping relationship between the second signal of the second method and the random access resource of the second method, the second mapping relationship is determined based on the second information, the second mapping relationship includes a mapping relationship between the second signal of the second method and the first signal of the first method, and accordingly, the first random access resource and the corresponding transmit beam are determined based on the mapping result.

[0062] In actual application, the first access network device can instruct the terminal on the mapping order, thereby causing the terminal to map according to one of the two mapping orders described above.

[0063] Based on this, one implementation example, the method, The process further includes receiving fifth information transmitted from the first access network device, the fifth information instructing to sequentially perform mapping between a first mapping relationship and a second mapping relationship based on the first information, or to sequentially perform mapping between a second mapping relationship and a first mapping relationship based on the first information.

[0064] In actual applications, the fifth information may be delivered via a system message. For example, in a heterogeneous network consisting of VLC and radio frequencies, the terminal obtains the fifth information via the radio frequency SIB1.

[0065] In the embodiment of the present invention, under a heterogeneous network construction structure, based on the first information, a first random access resource mapped by a second signal of the second method and the corresponding transmit beam are determined, and random access request information is transmitted on the first random access resource of the determined transmit beam. In an operating method that supports multiple beams, through the association between a random access resource and a first signal corresponding to a beam (different transmission signals of the first signal can identify different beams), the terminal transmits random access request information on the random access resource corresponding to the transmission signal of a specific first signal. In this way, implicit reporting of downlink beam selection is achieved while simultaneously reducing the overhead of beam scanning in subsequent processes.

[0066] In one embodiment, the random access request information is: The second type of random access sequence, This may include one of a second type of random access sequence and a PUSCH or PUCCH associated with the second type of random access sequence.

[0067] In actual application, if the random access request information includes a second type of random access sequence and a PUSCH or PUCCH associated with the second type of random access sequence, the first access network device will at least use the random access request information to determine which second access network device will be accessed by the terminal.

[0068] In response to this, embodiments of the present application further provide a resource transmission method performed by a first access network device, which includes the following steps, as shown in Figure 5.

[0069] In step 501, the first information is transmitted to the terminal, and the first access network device can provide the terminal with access in the first manner, and the first information is Second information indicating the relationship between the first signal of the first method and the second signal of the second method, wherein the first method differs from the second method in its second information, Configuration information for the second type of random access resource, Third information showing the relationship between the random access resource of the second method and the second signal of the second method, It includes at least one of the following: a second type of random access sequence format.

[0070] In step 502, the terminal receives random access request information of the second method transmitted via the beam corresponding to the first signal of the first method on a first random access resource mapped by the second signal of the second method.

[0071] In step 503, a second access network device to be accessed by the terminal is determined based on the location of the first random access resource and / or random access request information mapped by the second signal of the second method, and the second access network device can provide the terminal with access of the second method.

[0072] Here, in one embodiment, the method is This may further include transmitting a fourth piece of information to the terminal, which indicates whether or not to allow access in the second manner.

[0073] In actual application, in step 503, the first access network device also needs to determine, based on the first information, the establishment of mapping relationships between the second type random access resource, the second type second signal, and the first type first signal. Subsequently, based on the location of the first random access resource and / or random access request information and the established mapping relationships, the second access network device to be accessed by the terminal is determined.

[0074] Here, when establishing a mapping relationship, there are two possible embodiments, similar to those for terminals.

[0075] In the first method, mapping of a first mapping relationship and a second mapping relationship is performed sequentially based on the first information to obtain a mapping result, the first mapping relationship is determined based on the configuration information of the random access resource of the second method and the third information, the first mapping relationship includes a mapping relationship between the second signal of the second method and the random access resource of the second method, the second mapping relationship is determined based on the second information, the second mapping relationship includes a mapping relationship between the second signal of the second method and the first signal of the first method, and in correspondence thereto, the second access network device accessed by the terminal is determined in combination with the mapping result based on the location of the first random access resource and / or random access request information.

[0076] In the second method, based on the first information, the mapping of the second mapping relationship and the first mapping relationship is performed sequentially to obtain a mapping result, the first mapping relationship is determined based on the configuration information of the random access resource of the second method and the third information, the first mapping relationship includes a mapping relationship between the second signal of the second method and the random access resource of the second method, the second mapping relationship is determined based on the second information, the second mapping relationship includes a mapping relationship between the second signal of the second method and the first signal of the first method, and in correspondence thereto, based on the location of the first random access resource and / or random access request information, the second access network device accessed by the terminal is determined in combination with the mapping result.

[0077] In actual application, the first access network device can instruct the terminal on the mapping order, thereby causing the terminal to map according to one of the two mapping orders described above.

[0078] Based on this, one implementation example, the method, The further includes transmitting fifth information to the terminal, the fifth information instructing the terminal to sequentially perform mapping between a first mapping relationship and a second mapping relationship based on the first information, or to sequentially perform mapping between a second mapping relationship and a first mapping relationship based on the first information.

[0079] Embodiments of the present invention further provide a resource transmission method, which, as shown in Figure 6, includes the following steps.

[0080] In step 601, the first access network device transmits first information to the terminal, and the first access network device can provide the terminal with access in the first manner, and the first information is Second information indicating the relationship between the first signal of the first method and the second signal of the second method, wherein the first method differs from the second method in its second information, Configuration information for the second type of random access resource, Third information showing the relationship between the random access resource of the second method and the second signal of the second method, It includes at least one of the following: a second type of random access sequence format.

[0081] In step 602, after receiving the first information, the terminal determines, based on the first information, the first random access resource mapped by the second signal of the second method and the corresponding transmit beam, and transmits the random access request information of the second method to the first access network device.

[0082] In step 603, after receiving the random access request information, the first access network device determines the second access network device to be accessed by the terminal based on the first random access resource location and / or random access request information, and the second access network device can provide the terminal with access using the second method.

[0083] Embodiments of the present application provide a resource transmission method in which a first access network device transmits first information to a terminal, the first access network device can provide access in a first method to the terminal, the first information being second information indicating an association relationship between a first signal of the first method and a second signal of the second method, the first method being different from the second method, and including at least one of the second information, configuration information of a random access resource of the second method, third information indicating an association relationship between a random access resource of the second method and a second signal of the second method, and a random access sequence format of the second method, the terminal, after receiving the first information, determines a first random access resource mapped by a second signal of the second method and the corresponding transmit beam based on the first information, and transmits random access request information of the second method to the first access network device, the first access network device, after receiving the random access request information, determines a second access network device to be accessed by the terminal based on the location of the first random access resource and / or the random access request information, and the second access network device can provide access in a second method to the terminal. According to the solution provided in the embodiment of the present invention, the first access network device transmits information to the terminal, enabling the terminal to establish a mapping relationship between the second random access resource, the second signal of the second system, and the first signal of the first system. This enables the terminal to select the second random access resource and the optimal transmit beam, and transmit the corresponding random access request information. In this way, the first access network device can identify the second access network device that the terminal intends to access and receive it with the optimal uplink beam, thereby reducing initial access delay and improving the access process rate.

[0084] The present application will be described in more detail below with reference to application examples.

[0085] In the application example, a heterogeneous network is constructed using VLC and radio frequencies.

[0086] Application Example 1 In this application embodiment, the configuration information for visible light random access parameters is as follows: The mapping relationship between radio frequency SSB and visible light SSB (indicating which visible light SSB coverage area falls within the radio frequency SSB coverage area). Visible light random access time-frequency domain resource configuration information (referring to RO), The association between visible light random access resources and visible light SSBs (the association between visible light random access resources and visible light SSBs refers to the number of SSBs associated with each RO), It may include at least one of the following: visible light random access sequence formats (the visible light random access sequence format is different from or the same as the radio frequency random access sequence format).

[0087] Here, the configuration information for the optical random access parameters is transmitted to SIB1.

[0088] Since visible light RO and radio frequency RO are independent, the difference between the two ROs allows them to be separated into radio frequency and visible light, eliminating the need to configure different random access sequence formats for radio frequency and visible light.

[0089] Here, in order to further reduce the overhead of SIB1 information, the configuration of the visible light random access sequence format can be set to default, indicating that the visible light random access sequence default is the same as the radio frequency random access sequence. In this case, the configuration information may include the mapping relationship between radio frequency SSB and visible light SSB, the visible light random access time-frequency domain resource configuration, and the association relationship between visible light random access resources and visible light SSB.

[0090] Furthermore, the association relationship between visible light random access resources and visible light SSBs can also be set to default, indicating that the number of SSBs associated with each visible light RO is the same as the number of SSBs associated with each radio frequency RO. In this case, the configuration information includes only the mapping relationship between radio frequency SSBs and visible light SSBs, and the visible light random access time-frequency domain resource configuration.

[0091] After completing demodulation of the radio frequency downlink PBCH, the terminal obtains configuration information of the radio frequency and visible light random access parameters via the radio frequency SIB1. Here, the configuration information of the radio frequency random access parameters may be consistent with 5G NR and includes the random access sequence format, PRACH transmission opportunity, and the association relationship between random access resources and SSB.

[0092] Subsequently, the terminal determines whether or not to perform initial access to the visible light base station based on the signal quality of the received visible light SSB and the mapping relationship between radio frequency SSB and visible light SSB. Specifically, If the signal quality (e.g., RSRP) of all visible light base stations is below the first threshold, the terminal directly performs the radio frequency random access process according to the radio frequency random access parameter configuration. Otherwise, the terminal performs an initial access based on the visible light SSB with the best signal quality among the visible light SSBs that have a mapping relationship with the radio frequency SSB (improving the success rate of access). After determining the visible light SSB to be accessed and its associated RO, the terminal transmits the corresponding random access sequence over the uplink beam corresponding to the radio frequency SSB. A radio frequency base station can identify the visible light base station that a terminal is trying to access based on the time-frequency domain position of the RO and the random access sequence index (which can be written as "index" in English).

[0093] Here, the terminal establishes a mapping relationship between the visible light PRACH transmission resource and the visible light SSB and radio frequency SSB based on the configured information, and determines the RO and radio frequency SSB corresponding to the visible light SSB to be accessed based on the established mapping relationship.

[0094] The information configured here is First, the visible light SSB is mapped to the visible light RO, and then the visible light SSB is mapped to the radio frequency SSB; that is, the first method described above (referred to as method a in the following explanation) is used to establish the mapping relationship. First, it may involve mapping radio frequency SSB to visible light SSB and then mapping visible light SSB to visible light RO, or first mapping visible light SSB to radio frequency SSB and then mapping visible light SSB to visible light RO, that is, one of the second methods described above for establishing the mapping relationship (referred to as method b in the following explanation).

[0095] The solution in this application example will be described in detail below with reference to an example.

[0096] Example 1 In this example, the radio frequency base station transmits four SSBs: SSB0, SSB1, SSB2, and SSB3. Each visible light base station transmits one SSB. The four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3. The cell IDs of these four cells are ID0, ID1, ID2, and ID3. To distinguish them from the SSBs of the radio frequency base stations, the synchronization signal transmitted by the visible light base stations is called RS. The SSBs of the four visible light base stations are RS0 (visible light base station 0), RS1 (visible light base station 1), RS2 (visible light base station 2), and RS3 (visible light base station 3).

[0097] Assuming the terminal searches for SSB1 transmitted from the radio frequency base station, RS1 transmitted from visible light base station 1, and RS2 transmitted from visible light base station 2, demodulating SSB1 will yield the radio frequency base station cell ID, and demodulating RS1 and RS2 will yield visible light base station cell ID1 and cell ID2, respectively.

[0098] The terminal obtains configuration information for random access parameters via a radio frequency downlink, and it is assumed that the obtained configuration information includes the following: there are four ROs in the radio frequency time domain, each RO is mapped to one SSB, and the random access sequence format is A; and there are four visible light ROs in the visible light time domain, each RO is associated with one RS, and the visible light random access sequence format is B. The mapping relationship between radio frequency SSBs and visible light RSs is such that SSB0 corresponds to RS0, SSB1 corresponds to RS1, SSB2 corresponds to RS2, and SSB3 corresponds to RS3.

[0099] When the configuration information instructs the system to map according to method a, as shown in Figure 7, the terminal first maps RS to visible light RO to obtain {RS0-RO0}, {RS1-RO1}, {RS2-RO2}, {RS3-RO3}, then maps RS to SSB to obtain SSB0{RS0-RO0}, SSB1{RS1-RO1}, SSB2{RS2-RO2}, SSB3{RS3-RO3}, If the configuration information instructs the system to map according to method b, as shown in Figure 7, the terminal first maps the SSB to the RS to obtain {SSB0-RS0}, {SSB1-RS1}, {SSB2-RS2}, and {SSB3-RS3}, and then maps the RS to the visible light RO to obtain RO0{SSB0-RS0}, RO1{SSB1-RS1}, RO2{SSB2-RS2}, and RO3{SSB3-RS3}.

[0100] Assuming that the signal quality of RS1 is better than RS2, the terminal chooses to access the cell corresponding to ID1, i.e., cell 1, and then the terminal transmits one random access sequence via the uplink beam corresponding to the SSB1 downlink beam at RO1, and the radio frequency base station identifies visible light base station 1, based on the time-frequency domain position of RO1, that the terminal is trying to access.

[0101] Example 2 In this example, the radio frequency base station transmits four SSBs: SSB0, SSB1, SSB2, and SSB3. Each visible light base station transmits one SSB. The four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3. The cell IDs of these four cells are ID0, ID1, ID2, and ID3. To distinguish them from the SSBs of the radio frequency base stations, the synchronization signal transmitted by the visible light base stations is called RS. The SSBs of the four visible light base stations are RS0 (visible light base station 0), RS1 (visible light base station 1), RS2 (visible light base station 2), and RS3 (visible light base station 3).

[0102] Assuming the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from visible light base station 0, and RS1 transmitted from visible light base station 1, demodulating SSB1 will yield the radio frequency base station cell ID, and demodulating RS0 and RS1 will yield visible light base station cell IDs 0 and 1, respectively.

[0103] The terminal obtains configuration information for random access parameters via a radio frequency downlink, and assumes that the obtained configuration information includes the following: there are four ROs in the radio frequency time domain and four visible light ROs in the visible light time domain, one SSB / RS is associated with each radio frequency and visible light RO, the random access sequence format for both radio frequency and visible light is A, and the mapping relationship between radio frequency SSB and visible light RS is such that SSB0 corresponds to RS0 and RS1, SSB2 corresponds to RS2, and SSB3 corresponds to RS3.

[0104] When the configuration information instructs the system to map according to method a, as shown in Figure 8, the terminal first maps RS to visible light RO to obtain {RS0-RO0}, {RS1-RO1}, {RS2-RO2}, {RS3-RO3}, then maps RS to SSB to obtain SSB0{RS0-RO0}, SSB0{RS1-RO1}, SSB2{RS2-RO2}, SSB3{RS3-RO3}, If the configuration information instructs the system to map according to method b, as shown in Figure 8, the terminal first maps the SSB to the RS to obtain {SSB0-RS0}, {SSB0-RS1}, {SSB2-RS2}, and {SSB3-RS3}, and then maps the RS to the visible light RO to obtain RO0{SSB0-RS0}, RO1{SSB0-RS1}, RO2{SSB2-RS2}, and RO3{SSB3-RS3}.

[0105] Assuming that the signal quality of RS1 is better than RS0, the terminal chooses to access the cell corresponding to ID1, i.e., cell 1, and then the terminal transmits one random access sequence via the uplink beam corresponding to the SSB0 downlink beam at RO1, and the radio frequency base station identifies visible light base station 1, based on the time-frequency domain position of RO1, that the terminal is trying to access.

[0106] As can be seen from the above explanation, the number of radio frequency SSBs and the number of visible light SSBs (i.e., the number of visible light base stations) in Example 1 and Example 2 are the same. If the two are different, the processing process is the same as the process described above and will not be explained again here.

[0107] It should be explained here that in method a and method b described above, the number of visible light ROs occupied by the same or different numbers of radio frequency SSB and visible light SSB differs.

[0108] For illustrative purposes, assume that a radio frequency base station transmits four SSBs, SSB0, SSB1, SSB2, and SSB3, and each visible light base station transmits one SSB, resulting in a total of five visible light base stations corresponding to cells 0, 1, 2, 3, and 4, respectively, with cell IDs ID0, ID1, ID2, ID3, and ID4, respectively. Assume there are four ROs in the radio frequency time domain and five visible light ROs in the visible light time domain, with one SSB / RS associated with each radio frequency and visible light RO, and that the random access sequence format for both radio frequency and visible light is A. Figures 9a to 9c are schematic diagrams showing the relationship between the number of mapping relationships between radio frequency SSB and visible light SSB and the number of visible light base stations. As can be seen from Figures 9a to 9c, when the number of mapping relationships between radio frequency SSB and visible light SSB is equal to the number of visible light base stations, the number of visible light ROs occupied by methods a and b is the same. When the number of mapping relationships between radio frequency SSB and visible light SSB is greater than the number of visible light base stations, method a can occupy fewer visible light ROs. However, if one visible light SSB is restricted to corresponding to one radio frequency SSB, the number of visible light ROs occupied by methods a and b is the same. When the number of mapping relationships between radio frequency SSB and visible light SSB is less than the number of visible light base stations, method b can occupy fewer visible light ROs. Therefore, in actual application, the path command can be used to instruct the system to adopt method b to establish a mapping relationship between radio frequency SSB and visible light SSB, and in order to compress the overhead of system messages, if one visible light SSB corresponds to multiple radio frequency SSBs, one of the radio frequency SSBs should be selected.

[0109] Application Example 2 Given that the RO design for 5G NR occupies a significant amount of time-frequency resources, reconfiguring a new RO for visible light is difficult, and the overhead of SIB1 information is also large. Therefore, unlike Application Example 1, the configuration of visible light random access time-frequency domain resources in the configuration information of the visible light random access parameter can be set to default, indicating that the visible light RO is the same as the radio frequency RO by default. In this case, the configuration information of the visible light random access parameter may include the mapping relationship between radio frequency SSB and visible light SSB, the association relationship between visible light random access resources and visible light SSB, and the visible light random access sequence format.

[0110] After completing demodulation of the radio frequency downlink PBCH, the terminal obtains configuration information of the radio frequency and visible light random access parameters via the radio frequency SIB1. Here, the configuration information of the radio frequency random access parameters may be consistent with 5G NR and includes the random access sequence format, PRACH transmission opportunity, and the association relationship between random access resources and SSB.

[0111] Subsequently, the terminal determines whether to perform an initial access to a visible light base station based on the signal quality of the received visible light SSB and the mapping relationship between the radio frequency SSB and the visible light SSB. If the signal quality (e.g., RSRP) of all visible light base stations is below a first threshold, the terminal directly performs the radio frequency random access process according to the radio frequency random access parameter configuration. Otherwise, the terminal performs an initial access based on the visible light SSB with the best signal quality among the visible light SSBs that have a mapping relationship with the radio frequency SSB (improving the success rate of access). After determining the visible light SSB to be accessed and its associated RO, the terminal transmits the corresponding random access sequence over the uplink beam corresponding to the radio frequency SSB. A radio frequency base station can identify the visible light base station that a terminal is trying to access based on the RO's time-frequency domain position, random access sequence format, and random access sequence index.

[0112] Here, different random access sequence formats are used to identify whether the terminal is attempting to access a visible light base station or a radio frequency base station. To further reduce the overhead of SIB1 information, if we consider distinguishing between visible light base stations and radio frequency base stations through different indices in the same random access sequence format, i.e., by selecting different indices for visible light base stations and radio frequency base stations, the configuration of the visible light random access sequence format can be set to default, indicating that the visible light random access sequence default is the same as the radio frequency random access sequence. In this case, the configuration information of the visible light random access parameter may include the mapping relationship between radio frequency SSBs and visible light SSBs, and the association relationship between visible light random access resources and visible light SSBs. Furthermore, the association relationship between visible light random access resources and visible light SSBs can also be set to default, indicating that the number of SSBs associated with each visible light RO is the same as the number of SSBs associated with each radio frequency RO. In this case, the configuration information of the visible light random access parameter includes only the mapping relationship between radio frequency SSBs and visible light SSBs. In response, the radio frequency base station identifies the visible light base station that the terminal intends to access based on the time-frequency domain position of the RO and PUCCH / PUSCH associated with the random access sequence.

[0113] Here, the terminal establishes a mapping relationship between the visible light PRACH transmission resource and the visible light SSB and radio frequency SSB based on the configured information, and determines the RO and radio frequency SSB corresponding to the visible light SSB to be accessed based on the established mapping relationship.

[0114] The information configured here is First, the visible light SSB is mapped to the visible light RO, and then the visible light SSB is mapped to the radio frequency SSB; that is, the first method described above (referred to as method a in the following explanation) is used to establish the mapping relationship. First, it may involve mapping radio frequency SSB to visible light SSB and then mapping visible light SSB to visible light RO, or first mapping visible light SSB to radio frequency SSB and then mapping visible light SSB to visible light RO, that is, one of the second methods described above for establishing the mapping relationship (referred to as method b in the following explanation).

[0115] The solution in this application example will be described in detail below with reference to an example.

[0116] Example 1 In this example, the radio frequency base station transmits four SSBs: SSB0, SSB1, SSB2, and SSB3. Each visible light base station transmits one SSB. The four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3. The cell IDs of these four cells are ID0, ID1, ID2, and ID3. To distinguish them from the SSBs of the radio frequency base stations, the synchronization signal transmitted by the visible light base stations is called RS. The SSBs of the four visible light base stations are RS0 (visible light base station 0), RS1 (visible light base station 1), RS2 (visible light base station 2), and RS3 (visible light base station 3).

[0117] Assuming the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from visible light base station 0, and RS1 transmitted from visible light base station 1, demodulating SSB1 will yield the radio frequency base station cell ID, and demodulating RS0 and RS1 will yield visible light base station cell IDs 0 and 1, respectively.

[0118] Assuming that the terminal obtains configuration information for random access parameters via radio frequency downlink, and that the obtained configuration information includes the following: there are four ROs in the radio frequency and visible light time domains, one SSB is mapped to each radio frequency RO, the radio frequency random access sequence format is A; one RS is associated with each visible light RO, the visible light random access sequence format is B; and the mapping relationship between radio frequency SSBs and visible light RSs is such that SSB0 and SSB1 correspond to RS0, SSB2 corresponds to RS2, and SSB3 corresponds to RS3, then If the configuration information instructs the system to map according to method a, as shown in Figure 10, the terminal first maps RS to visible light RO to obtain {RS0-RO0}, {RS1-RO1}, {RS2-RO2}, {RS3-RO3}, then maps RS to SSB to obtain SSB0{RS0-RO0}, SSB1{RS0-RO0}, XXX{RS1-RO1}, SSB2{RS2-RO2}, SSB3{RS3-RO3}, If the configuration information instructs the mapping to follow method b, as shown in Figure 10, the terminal first maps the SSB to the RS to obtain {SSB0-RS0}, {SSB1-RS0}, {SSB2-RS2}, and {SSB3-RS3}, and then maps the RS to the visible light RO to obtain RO0{SSB0-RS0}, RO1{SSB1-RS0}, RO2{SSB2-RS2}, and RO3{SSB3-RS3}.

[0119] Assuming that the signal quality of RS1 is better than RS0, and considering that there is no uplink transmit beam corresponding to RS1, the terminal will choose to access the cell corresponding to ID0, i.e., cell 0.

[0120] Here, if the terminal is mapped according to scheme a, it can transmit over the uplink beams corresponding to SSB0 and SSB1 on RO0, and considering that the radio frequency base station also needs to receive the 5G terminal's preamble at the same time, the terminal chooses to transmit any one random access sequence of format B over the uplink beam corresponding to SSB0; if the terminal is mapped according to scheme b, it can transmit over the uplink beam corresponding to SSB0 on ​​RO0, or over the uplink beam corresponding to SSB1 on RO1, and the radio frequency base station identifies that the visible light base station 0 is the one the terminal is trying to access, based on the time-frequency domain position of RO0 or RO1 and the random access sequence format.

[0121] Example 2 In this example, the radio frequency base station transmits four SSBs: SSB0, SSB1, SSB2, and SSB3. Each visible light base station transmits one SSB. The four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3. The cell IDs of these four cells are ID0, ID1, ID2, and ID3. To distinguish them from the SSBs of the radio frequency base stations, the synchronization signal transmitted by the visible light base stations is called RS. The SSBs of the four visible light base stations are RS0 (visible light base station 0), RS1 (visible light base station 1), RS2 (visible light base station 2), and RS3 (visible light base station 3).

[0122] Assuming the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from visible light base station 0, and RS1 transmitted from visible light base station 1, demodulating SSB1 will yield the radio frequency base station cell ID, and demodulating RS0 and RS1 will yield visible light base station cell IDs 0 and 1, respectively.

[0123] Assume that the terminal obtains configuration information for random access parameters via a radio frequency downlink, and that the obtained configuration information includes the following: there are four ROs in the radio frequency and visible light time domains, with one SSB / RS mapped to each RO (i.e., associated); both the radio frequency and visible light random access sequence formats are A; and the mapping relationship between radio frequency SSB and visible light RS is such that SSB0 corresponds to RS0, SSB1 corresponds to RS1, SSB2 corresponds to RS1 and RS2, and SSB3 corresponds to RS3.

[0124] In this case, if the configuration information instructs the system to map according to method a, as shown in Figure 11, the terminal first maps RS to visible light RO to obtain {RS0-RO0}, {RS1-RO1}, {RS2-RO2}, {RS3-RO3}, then maps RS to SSB to obtain SSB0{RS0-RO0}, SSB1{RS1-RO1}, SSB2{RS1-RO1}, SSB2{RS2-RO2}, SSB3{RS3-RO3}, If the configuration information instructs the system to map according to method b, as shown in Figure 11, the terminal first maps SSB to RS to obtain {SSB0-RS0}, {SSB1-RS1}, {SSB2-RS1}, {SSB2-RS2}, and {SSB3-RS3}, and then maps RS to visible light RO to obtain RO0{SSB0-RS0}, RO1{SSB1-RS1}, RO2{SSB2-RS1}, RO3{SSB2-RS2}, and RO4{SSB3,RS3}.

[0125] Assuming that the signal quality of RS1 is better than that of RS0, the terminal will choose to access the cell corresponding to ID1, i.e., cell 1.

[0126] If the terminal is mapped according to scheme a, it can transmit over the uplink beams corresponding to SSB1 and SSB2 on RO1, and considering that the radio frequency base station also needs to receive the 5G terminal's preamble at the same time, the terminal can choose to transmit any one random access sequence on the uplink beam corresponding to SSB1.

[0127] In the case of mapping corresponding to method b, the terminal can transmit via the uplink beam corresponding to SSB1 on RO1, or via the uplink beam corresponding to SSB2 on RO2, and in this case, for other visible light ROs, the visible light receiving beam is different from the radio frequency receiving beam, so regardless of which base station is used, the terminal will not be able to access it, and therefore mapping using this method is not possible.

[0128] The random access request information transmitted here may specifically include the following two types of information:

[0129] The first type is one in which the random access request information includes a visible light random access sequence.

[0130] The starting numbers of the random access sequences associated with radio frequency SSB and visible light SSB terminals are different. Assuming there are a total of N sequences (where N is an integer greater than or equal to 2), the starting sequence number for RO1's radio frequency SSB is 0, and the starting sequence number for visible light RS is N / 2. However, this approach reduces the number of accessible terminals and affects legacy terminals.

[0131] The radio frequency base station can identify that the terminal is attempting to access is the visible light base station 1, based on the time-frequency domain position of RO1 and the random access sequence index.

[0132] The second type is one in which the random access request information includes a visible light random access sequence and associated PUSCH / PUCCH.

[0133] The starting number of the random access sequence associated with terminals in radio frequency SSB and visible light SSB is the same, in which case the terminal must transmit a preamble and a PUSCH / PUCCH associated with the preamble, where the content of the PUSCH / PUCCH can indicate whether the terminal is accessing a radio frequency or a visible light base station through a bitmap.

[0134] The radio frequency base station identifies visible light base station 1 as the one the terminal is attempting to access, based on RO1's time-frequency domain location, preamble, and PUCCH / PUSCH content associated with the preamble.

[0135] In Example 1 and Example 2, the number of radio frequency SSBs and the number of visible light SSBs (i.e., the number of visible light base stations) are the same. If the two are different, the processing process is the same as described above and will not be explained again here.

[0136] It should be explained that in methods a and b described above, if the number of radio frequency SSBs and the number of visible light SSBs are different, then in both methods a and b, regardless of the number of mapping relationships between radio frequency SSBs and visible light SSBs, there is a situation where the transmit beam corresponding to the radio frequency preamble competes with the transmit beam corresponding to the visible light preamble on the same RO. This results in a problem where some terminals cannot access the base station regardless of which transmit beam it receives.

[0137] For illustrative purposes, assume that a radio frequency base station transmits four SSBs, SSB0, SSB1, SSB2, and SSB3, and each visible light base station transmits one SSB, with a total of five visible light base stations corresponding to cells 0, 1, 2, 3, and 4 respectively, and that the cell IDs of these five cells are ID0, ID1, ID2, ID3, and ID4, respectively. Assume there are four ROs in the radio frequency and visible light time domains, with one SSB / RS associated with each radio frequency and visible light RO, and that the radio frequency random access sequence format is A and the visible light random access sequence format is B. Figures 12a-c are schematic diagrams showing the relationship between the number of mapping relationships between radio frequency SSB and visible light SSB and the number of visible light base stations. As can be seen from Figures 12a-c, when the number of radio frequency SSBs and the number of visible light SSBs are different, in both method a and method b, regardless of the number of mapping relationships between radio frequency SSB and visible light SSB, there is a situation where the transmit beam corresponding to the radio frequency preamble competes with the transmit beam corresponding to the visible light preamble on the same RO. This results in a problem where some terminals cannot access the base station regardless of which transmit beam it receives.

[0138] Therefore, when the number of visible light base stations is equal to the number of radio frequency SSBs, the mapping relationship between radio frequency SSBs and visible light SSBs can be realized by signaling configuration scheme a. In order to compress the overhead of system messages, if one visible light SSB corresponds to multiple radio frequency SSBs, the mapping relationship between radio frequency SSBs and radio frequency random access resources is combined to select one of the radio frequency SSBs, and it is ensured that the relevant radio frequency SSB and the radio frequency SSB associated with the visible light SSB are the same in the same visible light RO.

[0139] In the application embodiment of the present invention, the radio frequency link may be a cellular network (4G / 5G, etc.) uplink / downlink, and by establishing a mapping relationship between visible light PRACH transmission resources and visible light SSB and radio frequency SSB through the design of a random access resource transmission method for constructing a visible light heterogeneous network, the delay of terminal access to the visible light base station is reduced and the access process rate is improved.
