Description

[Technical field]

[0001] The present application relates to wireless communication technology, and in particular to a resource transmission method, an associated device, and a storage medium.

[0002] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application is filed based on a Chinese patent application bearing application number 202111639888.X, filed with the China Patent Office on December 29, 2021, and claims priority to the Chinese patent application, the entire contents of which are incorporated herein by reference. [Background technology]

[0003] Indoor visible light communication (VLC) is a new type of high-speed, environmentally friendly indoor access network technology that uses the fast blinking of light-emitting diode (LED) lighting to transmit information and uses free space as a transmission channel. The light emitted by the LED lighting, which is the light source, has a certain directivity, so its coverage range is narrow, and when a user moves into an area that VLC cannot cover, the service is interrupted. Meanwhile, compared with the transparency of wireless communication, VLC is easily affected by obstructions, and the communication link is interrupted. Furthermore, considering the difficulty of realizing a visible light uplink in practical applications, VLC can be combined with other wireless access methods to construct a heterogeneous network. For example, taking wireless frequency as an example, as shown in Figure 1, in the heterogeneous network construction of VLC, it is assumed that visible light only has a downlink and no uplink, while wireless frequency links have both uplink and downlink.

[0032] In the following, the present application will be explained in more detail with reference to the figures and examples.

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

[0034] However, as can be seen from the process shown in Figure 2, in the initial access process of visible light heterogeneous network construction, when a terminal wants to access a visible light base station, it must first access a radio frequency base station, report all the measured visible light downlink qualities to the radio frequency base station, and then add and communicate with an appropriate visible light base station through the radio frequency base station, which process is relatively time-consuming. Therefore, as shown in Figure 3, in the radio frequency access stage, the terminal can select and directly access a visible light downlink, in this way, the measurement report and radio frequency base station reconfiguration process are omitted, thereby reducing the initial access delay and improving the access process rate.

[0035] Here, in the initial access process of constructing a heterogeneous network, how does a terminal receive a synchronization signal / physical broadcast channel block (SSB: Synchronized Signal / PBCH (Physical Broadcast Channel) Block) transmitted from a radio frequency downlink and a visible light downlink and select a corresponding physical random access channel (PRACH: Physical Random Access Channel) transmission resource so that a radio frequency base station can not only identify a visible light base station that the terminal is trying to access, but also receive it with an optimal uplink beam?Currently, there is no effective solution.

[0036] In view of this, in various embodiments of the present application, the access network equipment of the first scheme transmits information to the terminal, thereby enabling the terminal to establish a mapping relationship between the random access resource of the second scheme, the second signal (which may also be referred to as a synchronization signal) of the second scheme, and the first signal (which may also be referred to as a synchronization signal) of the first scheme, thereby enabling the terminal to select the random access resource of the second scheme and an optimal transmission beam, and transmit corresponding random access request information, thus enabling the access network equipment of the first scheme to identify the access network equipment of the second scheme that the terminal is attempting to access, and receiving it on the optimal uplink beam, thereby reducing the initial access delay and improving the access process rate.

[0037] An embodiment of the present application provides a resource transmission method performed by a terminal, and as shown in FIG. 4, the method includes the following steps:

[0038] In step 401, first information is received from a first access network device, and the first access network device can provide a first mode of access to the terminal, and the first information includes: second information indicating an association relationship between a first signal of the first scheme and a second signal of a second scheme, where a second access network device can provide access of a second scheme to the terminal, and the first scheme is different from the second scheme; Configuration information of a random access resource of a second method; Third information indicating an association relationship between the random access resource of the second scheme and the second signal of the second scheme; The random access sequence (preamble) format of the second method is included.

[0039] In step 402, based on the first information, determine a first random access resource and a corresponding transmission beam mapped by a second signal of a second scheme, and send random access request information of the second scheme to a first access network device.

[0040] Here, in practical applications, the terminal may also be called User Equipment (UE), terminal equipment, equipment, or user.

[0041] The first access network device and the second access network device form a heterogeneous network. The first access network device is also called a Master Node (MN), and the second access network device is also called a Secondary Node (SN).

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

[0043] In one embodiment, the second access method includes optical communication access, specifically, may be VLC access (also referred to as 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, correspondingly, the first access network equipment may include a radio frequency access point (AP) (also referred to as a radio frequency base station), and the second access network equipment includes a Radio Link Control (RLC) AP (also referred to as a visible light base station).

[0044] Here, the terminal can receive data and control information transmitted from the first access network device via a 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 a radio frequency uplink. In this case, the terminal is in a heterogeneous network consisting of VLC and radio frequency. In this heterogeneous network, the heterogeneous network construction refers to a VLC downlink (also called a visible light downlink) and a radio frequency uplink, and the radio frequency downlink can be turned on on demand.

[0045] The association 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 is within the coverage range of the first signal of the first method. For example, in a heterogeneous network consisting of VLC and radio frequency, the association 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 is within the coverage range of radio frequency SSB.

[0046] Here, in practical application, when a second signal of one second scheme can correspond to at least two first signals of the first scheme, in order to save signaling overhead, in the association relationship indicated by the second information, a second signal of one second scheme only corresponds to a first signal of one first scheme.

[0047] The configuration information of the random access resource of the second scheme may include the PRACH transmission opportunity (abbreviated as RO) of the second scheme. Here, in practical application, the RO of the second scheme and the RO of the first scheme may be independent (i.e., the ROs of the two are different) or may not be independent (i.e., the ROs of the two are the same). If the RO of the second scheme is the same as the RO of the first scheme, the configuration information of the random access resource of the second scheme may be defaulted to save signaling overhead, which indicates that the configuration information of the random access resource of the second scheme is the same as the configuration information of the random access resource of the first scheme by default.

[0048] The association relationship between the random access resource of the second scheme and the second signal of the second scheme refers to the number of second signals of the second scheme associated with each random access resource of the second scheme. For example, in a heterogeneous network consisting of VLC and radio frequency, the association relationship between the random access resource of the second scheme and the second signal of the second scheme refers to the number of visible light SSBs associated with each visible light RO. For example, assume that there are four ROs, RO1, RO2, RO3, and RO4, and when the association relationship between the random access resources of the second scheme and the second signal of the second scheme indicates that one visible light SSB (for simplicity, referred to as Reference Signal (RS)) is associated with each visible light RO, RS1 is mapped to RO1, RS2 is mapped to RO2, RS3 is mapped to RO3, and RS4 is mapped to RO4; when the association relationship between the random access resources of the second scheme and the second signal of the second scheme indicates that two RSs are associated with each visible light RO, 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 random access resources of the second scheme can be mapped in a default order. Here, in practical application, the number of second signals associated with each random access resource of the second scheme may be the same as or different from the number of first signals associated with each random access resource of the first scheme. When the number of second signals associated with the random access resources of each second scheme is the same as the number of first signals associated with the random access resources of each first scheme, in order to save signaling overhead, the configuration of the association relationship between the random access resources of the second scheme and the second signals of the second scheme can be defaulted, representing that the number of second signals associated with the random access resources of each second scheme is the same as the number of first signals associated with the random access resources of each first scheme by default.

[0049] The random access sequence format of the second scheme may be the same as or different from the random access sequence format of the first scheme. Here, when the RO of the first scheme and the RO of the second scheme are independent, it is possible to distinguish the first scheme and the second scheme through different ROs, so that the same random access sequence format can be configured for the first scheme and the second scheme. In this case, in order to reduce signaling overhead, the configuration of the random access sequence format of the second scheme can be defaulted, which indicates that the random access sequence of the second scheme is the same as the random access sequence of the first scheme by default.

[0050] In practical application, the first information can be carried in a system message, for example, in a heterogeneous network consisting of VLC and radio frequency, after the terminal completes demodulation of the radio frequency downlink physical broadcast channel (PBCH), it receives the remaining minimum system message (i.e., SIB1) through the radio frequency downlink to obtain the configuration information of the radio frequency random access parameters and the configuration information of the visible light random access parameters (i.e., the first information). Here, the configuration information of the RF random access parameters is consistent with 5G NR, and includes a random access sequence format, a PRACH transmission opportunity, an association relationship between the random access resource and the SSB, etc.

[0051] Here, in practical application, in order to maintain backward compatibility, the first access network device can additionally instruct the terminal whether to allow access of the second scheme.

[0052] Based on this, in one embodiment, the method comprises: The method may further include transmitting fourth information to the terminal, the fourth information indicating whether to allow access of a second method.

[0053] Here, in practical applications, the fourth information may be carried on the PBCH.

[0054] If the fourth information indicates that access of the second method is permitted, the terminal executes step 402 .

[0055] For example, in a heterogeneous network consisting of VLC and radio frequencies, compared with conventional 5G New Radio (NR) systems, the content carried in the SSB transmitted from the 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, and when the bit is set to 1, it indicates that the radio frequency AP allows access from a visible light AP, and when the bit is set to 0, it indicates that the radio frequency AP does not allow access from a visible light AP.

[0056] In practical application, in step 402, the terminal judges whether to perform initial access of the second scheme based on the signal quality of the second signal of at least one received second access network device and the first information. Specifically, if the signal qualities (e.g., Reference Signal Received Power (RSRP)) of all the second signals are lower than a first threshold (which can be set as needed), the terminal directly performs the random access process of the first scheme based on the random access parameter configuration information of the first scheme; if the signal quality of at least one second signal is equal to or higher than the first threshold, the terminal performs initial access of the second scheme based on the second signal with the best signal quality, thereby improving the access success rate.

[0057] Here, after determining the optimal second signal, the terminal determines a first random access resource (i.e., a random access resource corresponding to the second signal having the best signal quality) and a corresponding transmission beam to be mapped by the second signal of the second scheme based on the first information, and sends random access request information of the second scheme to the first access network equipment.

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

[0059] Here, when establishing the mapping relationship, there are two possible embodiments:

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

[0061] In a second scheme, based on the first information, sequentially perform mapping of a second mapping relationship and the first mapping relationship to obtain a mapping result, wherein the first mapping relationship is determined based on configuration information of a random access resource of the second scheme and the third information, the first mapping relationship includes a mapping relationship between a second signal of the second scheme and a random access resource of the second scheme, the second mapping relationship is determined based on the second information, and the second mapping relationship includes a mapping relationship between a second signal of the second scheme and a first signal of the first scheme, and correspondingly, determine the first random access resource and a corresponding transmission beam based on the mapping result.

[0062] Here, in practical application, the first access network device can instruct the terminal to a mapping order, so that the terminal performs mapping according to one of the above two mapping orders.

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

[0064] Here, in practical application, the fifth information may be carried in a system message. Exemplarily, in a heterogeneous network consisting of VLC and radio frequency, the terminal obtains the fifth information through a radio frequency SIB1.

[0065] In an embodiment of the present application, under a heterogeneous network construction structure, based on the first information, a first random access resource and a corresponding transmission beam mapped by the second signal of the second scheme are determined, and random access request information is sent on the first random access resource of the determined transmission beam; in an operation scheme supporting multiple beams, through the association relationship between the random access resource and the first signal corresponding to the beam (different transmission signals of the first signal can identify different beams), the terminal sends random access request information on the random access resource corresponding to the transmission signal of a specific first signal, thus realizing implicit reporting of downlink beam selection and at the same time reducing the overhead of beam scanning in subsequent processes.

[0066] In one embodiment, the random access request information comprises: A random access sequence of the second method; and a random access sequence of a second scheme and a PUSCH or a PUCCH associated with the random access sequence of the second scheme.

[0067] Here, in practical application, when the random access request information includes a random access sequence of a second scheme and a PUSCH or PUCCH associated with the random access sequence of the second scheme, the first access network device at least uses the random access request information to determine a second access network device to be accessed by the terminal.

[0068] Correspondingly, an embodiment of the present application further provides a resource transmission method, performed by a first access network device, as shown in FIG. 5, the method includes the following steps:

[0069] In step 501, first information is sent to a terminal, and the first access network device can provide a first mode of access to the terminal, and the first information includes: second information indicating an association relationship between a first signal of the first method and a second signal of a second method, the first method being different from the second method; Configuration information of a random access resource of a second method; Third information indicating an association relationship between the random access resource of the second scheme and the second signal of the second scheme; and a random access sequence format of the second scheme.

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

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

[0072] wherein, in one embodiment, the method comprises: The method may further include transmitting fourth information to the terminal, the fourth information indicating whether to allow access of a second method.

[0073] In practical application, in step 503, the first access network device also needs to determine, based on the first information, the establishment of a mapping relationship between the random access resource of the second scheme, the second signal of the second scheme, and the first signal of the first scheme, and then determine, based on the first random access resource location and / or random access request information, the established mapping relationship, the second access network device to be accessed by the terminal.

[0074] Here, when establishing a mapping relationship, as with the terminal, there may be the following two embodiments:

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

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

[0077] Here, in practical application, the first access network device can instruct the terminal to a mapping order, so that the terminal performs mapping according to one of the above two mapping orders.

[0078] Based on this, in one embodiment, the method comprises: The method may further include transmitting fifth information to the terminal, the fifth information instructing the terminal to sequentially perform mapping between the first mapping relationship and the second mapping relationship based on the first information, or instructing the terminal to sequentially perform mapping between the second mapping relationship and the first mapping relationship based on the first information.

[0079] An embodiment of the present application further provides a resource transmission method, as shown in FIG. 6, the method includes the following steps:

[0080] In step 601, a first access network device transmits first information to a terminal, the first access network device being capable of providing a first manner of access to the terminal, and the first information includes: second information indicating an association relationship between a first signal of the first method and a second signal of a second method, the first method being different from the second method; Configuration information of a random access resource of a second method; Third information indicating an association relationship between the random access resource of the second scheme and the second signal of the second scheme; and a random access sequence format of the second scheme.

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

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

[0083] An embodiment of the present application provides a resource transmission method, in which a first access network device transmits first information to a terminal, and the first access network device can provide access of a first scheme to the terminal, and the first information includes at least one of: second information indicating an association relationship between a first signal of the first scheme and a second signal of a second scheme, where the first scheme is different from the second scheme; configuration information of a random access resource of the second scheme; third information indicating an association relationship between a random access resource of the second scheme and a second signal of the second scheme; and a random access sequence format of the second scheme; after receiving the first information, the terminal determines a first random access resource and a corresponding transmission beam mapped by the second signal of the second scheme based on the first information, and transmits random access request information of the second scheme to the first access network device; after receiving the random access request information, the first access network device determines a second access network device to be accessed by the terminal based on the first random access resource location and / or the random access request information, and the second access network device can provide access of the second scheme to the terminal. According to the solution of the embodiment of the present application, the access network equipment of the first scheme sends information to the terminal, thereby enabling the terminal to establish a mapping relationship between the random access resource of the second scheme, the second signal of the second scheme, and the first signal of the first scheme, so as to enable the terminal to select the random access resource of the second scheme and the optimal transmission beam, and send corresponding random access request information, thus enabling the access network equipment of the first scheme to identify the access network equipment of the second scheme that the terminal wishes to access, and receive it through the optimal uplink beam, thereby reducing the delay of initial access and improving the access process rate.

[0084] In the following, the present application will be described in more detail with reference to application examples.

[0085] In an application example, a heterogeneous network is formed by VLC and radio frequency.

[0086] Application Example 1 In this application example, the configuration information of the visible light random access parameters is: The mapping relationship between radio frequency SSB and visible light SSB (which visible light SSB coverage area is within the radio frequency SSB coverage area), Visible light random access time-frequency domain resource configuration information (referred to as RO); The association relationship between the visible light random access resource and the visible light SSB (the association relationship between the visible light random access resource and the visible light SSB refers to the number of SSBs associated with each RO); visible light random access sequence format (wherein the visible light random access sequence format is different or the same as the radio frequency random access sequence format).

[0087] Here, configuration information of the optical random access parameters is carried in SIB1.

[0088] Because the visible light RO and the radio frequency RO are independent, due to the differences between the two ROs, they can be divided into radio frequency and visible light, and there is no 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 defaulted, which indicates 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 the radio frequency SSB and the visible light SSB, the visible light random access time-frequency domain resource configuration, and the association relationship between the visible light random access resource and the visible light SSB.

[0090] In addition, the association relationship between the visible light random access resource and the visible light SSB can also be defaulted, which indicates 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. Then, the configuration information only includes the mapping relationship between the radio frequency SSB and the visible light SSB, and the visible light random access time-frequency domain resource configuration.

[0091] After completing the demodulation of the radio frequency downlink PBCH, the terminal obtains the configuration information of radio frequency and visible light random access parameters through the radio frequency SIB1, where the configuration information of the radio frequency random access parameters may be consistent with 5G NR, including a random access sequence format, a PRACH transmission opportunity, and an association relationship between the random access resource and the SSB, etc.

[0092] Then, the terminal judges whether 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 the radio frequency SSB and the visible light SSB, specifically, If the signal qualities (e.g., RSRP) of all the visible light base stations are all less than the first threshold, the terminal directly performs a radio frequency random access process according to the radio frequency random access parameter configuration; otherwise, the terminal performs initial access based on the visible light SSB with the best signal quality in the visible light SSB having a mapping relationship with the radio frequency SSB (improving the access success rate); after the terminal determines the visible light SSB to be accessed and the RO associated therewith, transmits a corresponding random access sequence via an uplink beam corresponding to the radio frequency SSB; The radio frequency base station can identify the visible light base station that the terminal wishes to access based on the time-frequency domain location 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 the 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] Here, the configured information is First, map the visible light SSB to the visible light RO, and then map the visible light SSB to the radio frequency SSB, i.e., the above first method (hereinafter referred to as method a) when establishing the mapping relationship; This may include one of the following: first, 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, i.e., the above second method (referred to as method b in the following description) when establishing the mapping relationship.

[0095] The solution of this application embodiment is 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, and each visible light base station transmits one SSB, and the total of four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3, respectively, and the cell IDs of these four cells are ID0, ID1, ID2, and ID3, respectively, and in order to distinguish it from the SSB of the radio frequency base station, the synchronization signal transmitted by the visible light base station is called RS, and 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), respectively.

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

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

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

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

[0101] Example 2 In this example, the radio frequency base station transmits four SSBs, SSB0, SSB1, SSB2, and SSB3, and each visible light base station transmits one SSB, and the total of four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3, respectively, and the cell IDs of these four cells are ID0, ID1, ID2, and ID3, respectively, and in order to distinguish it from the SSB of the radio frequency base station, the synchronization signal transmitted by the visible light base station is called RS, and 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), respectively.

[0102] Assuming that the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from the visible light base station 0, and RS1 transmitted from the visible light base station 1, the radio frequency base station cell ID is obtained by demodulating SSB1, and the visible light base station cell ID0 and cell ID1 are obtained by demodulating RS0 and RS1, respectively.

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

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

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

[0106] As can be seen from the above description, 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, and when the two are different, the processing process is the same as the above process and will not be repeated here.

[0107] Here, it should be noted that in the above method a and the above method b, the number of visible light RO occupied by the same or different numbers of radio frequency SSBs and visible light SSBs is different.

[0108] For illustration, assume that a radio frequency base station transmits four SSBs, SSB0, SSB1, SSB2, and SSB3, each visible light base station transmits one SSB, and the total of five visible light base stations correspond to cell 0, cell 1, cell 2, cell 3, and cell 4, respectively, and the cell IDs of these five cells are ID0, ID1, ID2, ID3, and ID4, respectively. Assume that there are four ROs in the radio frequency time domain and five visible light ROs in the visible light time domain, one SSB / RS is associated with both each radio frequency and visible light RO, and the random access sequence formats of both the radio frequency and visible light are A. Figures 9a-c are schematic diagrams of the relationship between the number of mapping relationships between radio frequency SSBs and visible light SSBs and the number of visible light base stations. As can be seen from Figures 9a-c, when the number of mapping relationships between radio frequency SSBs and visible light SSBs is equal to the number of visible light base stations, the number of visible light ROs occupied by scheme a and scheme b are the same; when the number of mapping relationships between radio frequency SSBs and visible light SSBs is greater than the number of visible light base stations, scheme a can occupy fewer visible light ROs, but if one visible light SSB is restricted to correspond to one radio frequency SSB, the number of visible light ROs occupied by schemes a and b are the same; and when the number of mapping relationships between radio frequency SSBs and visible light SSBs is smaller than the number of visible light base stations, scheme b can occupy fewer visible light ROs. Therefore, in practical applications, a path command can be used to instruct the adoption of method b to establish a mapping relationship between radio frequency SSBs and visible light SSBs, and in order to compress the overhead of system messages, when one visible light SSB corresponds to multiple radio frequency SSBs, only one of them is selected.

[0109] Application Example 2 Considering that the RO design of 5G NR occupies many time-frequency resources, it is difficult to reconfigure a new RO for visible light, and the overhead of SIB1 information is also large. Therefore, different from the application embodiment 1, the configuration of the visible light random access time-frequency domain resource in the configuration information of the visible light random access parameter can be defaulted, which indicates 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 the radio frequency SSB and the visible light SSB, the association relationship between the visible light random access resource and the visible light SSB, and the visible light random access sequence format.

[0110] After completing the demodulation of the radio frequency downlink PBCH, the terminal obtains the configuration information of radio frequency and visible light random access parameters through the radio frequency SIB1, where the configuration information of the radio frequency random access parameters may be consistent with 5G NR, including a random access sequence format, a PRACH transmission opportunity, and an association relationship between the random access resource and the SSB, etc.

[0111] Then, the terminal judges whether to perform initial access of 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 qualities (e.g., RSRP) of all the visible light base stations are all lower than the first threshold, the terminal directly performs a radio frequency random access process according to the radio frequency random access parameter configuration; otherwise, the terminal performs initial access based on the visible light SSB with the best signal quality among the visible light SSBs having a mapping relationship with the radio frequency SSB (the access success rate is improved); after the terminal determines the visible light SSB to be accessed and the RO associated therewith, transmits a corresponding random access sequence via an uplink beam corresponding to the radio frequency SSB; The radio frequency base station can identify the visible light base station that the terminal wishes to access based on the time-frequency domain location of the RO, the random access sequence format, and the random access sequence index.

[0112] Here, through different random access sequence formats, it is identified whether the terminal is trying to access a visible light base station or a radio frequency base station. Considering that the visible light base station and the radio frequency base station are distinguished through different indexes of the same random access sequence format to further reduce the overhead of SIB1 information, that is, by selecting different indexes for the visible light base station and the radio frequency base station, the configuration of the visible light random access sequence format can be defaulted, which indicates 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 parameters may include the mapping relationship between the radio frequency SSB and the visible light SSB, and the association relationship between the visible light random access resource and the visible light SSB. Furthermore, the association relationship between the visible light random access resource and the visible light SSB can also be defaulted, which indicates 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 parameters only includes the mapping relationship between the radio frequency SSB and the visible light SSB. Correspondingly, the radio frequency base station identifies the visible light base station that the terminal intends to access based on the time-frequency domain location of the RO, the 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 the 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] Here, the configured information is First, map the visible light SSB to the visible light RO, and then map the visible light SSB to the radio frequency SSB, i.e., the above first method (hereinafter referred to as method a) when establishing the mapping relationship; This may include one of the following: first, 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, i.e., the above second method (referred to as method b in the following description) when establishing the mapping relationship.

[0115] The solution of this application embodiment is 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, and each visible light base station transmits one SSB, and the total of four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3, respectively, and the cell IDs of these four cells are ID0, ID1, ID2, and ID3, respectively, and in order to distinguish it from the SSB of the radio frequency base station, the synchronization signal transmitted by the visible light base station is called RS, and 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), respectively.

[0117] Assuming that the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from the visible light base station 0, and RS1 transmitted from the visible light base station 1, the radio frequency base station cell ID is obtained by demodulating SSB1, and the visible light base station cell ID0 and cell ID1 are obtained by demodulating RS0 and RS1, respectively.

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

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

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

[0121] Example 2 In this example, the radio frequency base station transmits four SSBs, SSB0, SSB1, SSB2, and SSB3, and each visible light base station transmits one SSB, and the total of four visible light base stations correspond to four cells, namely cell 0, cell 1, cell 2, and cell 3, respectively, and the cell IDs of these four cells are ID0, ID1, ID2, and ID3, respectively, and in order to distinguish it from the SSB of the radio frequency base station, the synchronization signal transmitted by the visible light base station is called RS, and 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), respectively.

[0122] Assuming that the terminal searches for SSB1 transmitted from the radio frequency base station, RS0 transmitted from the visible light base station 0, and RS1 transmitted from the visible light base station 1, the radio frequency base station cell ID is obtained by demodulating SSB1, and the visible light base station cell ID0 and cell ID1 are obtained by demodulating RS0 and RS1, respectively.

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

[0124] At this time, if the configuration information indicates that mapping is performed according to scheme a, as shown in FIG. 11, the terminal first maps the RS to the visible light RO to obtain {RS0-RO0}, {RS1-RO1}, {RS2-RO2}, and {RS3-RO3}, and then maps the RS to the SSB to obtain SSB0{RS0-RO0}, SSB1{RS1-RO1}, SSB2{RS1-RO1}, SSB2{RS2-RO2}, and SSB3{RS3-RO3}; When the configuration information indicates to map according to scheme b, as shown in FIG. 11, the terminal first maps SSB to RS to obtain {SSB0-RS0}, {SSB1-RS1}, {SSB2-RS1}, {SSB2-RS2}, {SSB3-RS3}, and then maps RS to visible light RO to obtain RO0{SSB0-RS0}, RO1{SSB1-RS1}, RO2{SSB2-RS1}, RO3{SSB2-RS2}, RO4{SSB3,RS3}.

[0125] Assuming that the signal quality of RS1 is better than RS0, the terminal selects to access the cell corresponding to ID1, ie, cell1.

[0126] When the terminal is mapped according to scheme a, it can transmit via 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] Here, in the case of mapping corresponding to scheme b, the terminal can transmit via an uplink beam corresponding to SSB1 on RO1, or can transmit any one random access sequence via an uplink beam corresponding to SSB2 on RO2; in this case, for other visible light ROs, the visible light receiving beam is different from the radio frequency receiving beam, so no matter which one the base station uses, the terminal will not be able to access, and therefore cannot be mapped using this scheme.

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

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

[0130] Assuming that the starting numbers of the random access sequences associated with terminals for radio frequency SSB and visible light SSB are different and there are a total of N sequences (N is an integer greater than or equal to 2), the sequence starting number of the radio frequency SSB in RO1 is 0 and the sequence starting number of the visible light RS is N / 2. However, such a scheme reduces the number of terminals that can access it, affecting legacy terminals.

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

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

[0133] The starting numbers of the random access sequences associated with terminals of radio frequency SSB and visible light SSB are the same, and at this time, the terminal needs to transmit a preamble and a PUSCH / PUCCH related to the preamble, where the content of the PUSCH / PUCCH can indicate through a bitmap whether the terminal is accessing a radio frequency or visible light base station.

[0134] The radio frequency base station identifies that it is the visible light base station 1 that the terminal is trying to access based on the time-frequency domain location of RO1, the preamble and the PUCCH / PUSCH content associated with the preamble.

[0135] 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, and when the two are different, the processing process is the same as the above process and will not be repeated here.

[0136] Here, it should be noted that when the number of radio frequency SSBs and the number of visible light SSBs are different in the above-mentioned method a and the above-mentioned method b, regardless of the number of mapping relationships between radio frequency SSBs and visible light SSBs, in both method a and method b, a situation exists in which the transmission beam corresponding to the radio frequency preamble competes with the transmission beam corresponding to the visible light preamble on the same RO, and a problem occurs in which some terminals cannot access regardless of which transmission beam the radio frequency base station receives.

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

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

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