[0063] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0064] interference

[0065] For the network with a frequency of 700Mhz, consistent with the NR network with a frequency of 2.6GHz, physical random access channel (PRACH) resources and physical uplink control channel (PUCCH) resources are deployed at the front and back ends of the entire bandwidth, among which PRACH resources are used for terminals to initiate random access, and PUCCH resources are used for terminals to send uplink control information.

[0066] For the 700MHz network, the uplink interference increased by 30 to 50dB, to -80 to -50dBm, causing the terminal to be unable to access the network for business. For 700MHz, according to field scanning information, the interference follows an 8MHz pattern, that is, there is a large interference every 8M, or there is no interference within 8M.

[0067] For terminals in the connected state, the network side can obtain the interference environment in the frequency domain through the SRS reported by the terminal, and avoid frequency domain resources with greater interference when performing uplink scheduling for the terminal. However, for terminals in the idle state, the network side cannot obtain the interference environment in the frequency domain. If the network side configures PRACH resources and PUCCH resources on frequency domain resources with greater interference, the terminal will fail to perform random access and will not be able to do business.

[0068] In one solution, the frequency domain resources with greater interference can be determined by frequency scanning, and then the network can configure PRACH resources and PUCCH resources to the frequency domain resources with lower interference to meet the terminal access requirements. However, the 700MHz interference is greatly affected by the business, and the frequency band where the interference occurs varies greatly. The only rule is that the interference occurs every 8M.

[0069] Relationship between SSB and RO

[0070] RO is also known as PRACH resource, which is used by the terminal to initiate random access. There is an association relationship between RO and SSB, where the association relationship between RO and SSB is determined according to the following parameters:

[0071] The parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB can be regarded as two parts. One part is ssb-perRACH-Occasion, which is used to indicate how many SSBs a RO corresponds to; the other part is CB-PreamblesPerSSB, which is used to indicate how many contention-based preambles are mapped on each SSB.

[0072] The parameter MSG1-FDM is used to indicate the number of ROs configured in the frequency domain, that is, the number of ROs included in the same time domain resource.

[0073] As an example, ssb-perRACH-OccasionAndCB-PreamblesPerSSB = 1, MSG1-FDM = 4, SSB_index = 8, then the association relationship between SSB and RO is as follows Figure 2 As shown, each rectangular box represents a RO, and the SSB associated with the RO is marked in the rectangular box.

[0074] As an example, ssb-perRACH-OccasionAndCB-PreamblesPerSSB = 2, MSG1-FDM = 4, SSB_index = 8, then the association relationship between SSB and RO is as follows Figure 3 As shown, each rectangular box represents a RO, and the SSB associated with the RO is marked in the rectangular box.

[0075] As an example, ssb-perRACH-OccasionAndCB-PreamblesPerSSB = 1 / 2, MSG1-FDM = 4, SSB_index = 8, then the association relationship between SSB and RO is as follows Figure 4 As shown, each rectangular box represents a RO, and the SSB associated with the RO is marked in the rectangular box.

[0076] from Figures 2 to 4 It can be seen that the frequency domain resources of the RO corresponding to the same SSB are almost the same. When the same terminal accesses at the same location, the probability of using the same SSB is relatively high, which will lead to the failure of the terminal to access the RO with the same frequency domain resources under the condition of continuous frequency band interference due to interference.

[0077] To this end, the following technical solutions of the embodiments of the present application are proposed. The technical solutions of the embodiments of the present application propose a new random access resource allocation method. On the one hand, by adjusting the starting position and / or each hop position of the RO, the terminal can achieve random access in different frequency domains, so that the terminal can access and do business in the bandwidth with low uplink interference. On the other hand, in order to adaptively respond to the interference frequency band situation, the RO frequency hopping deployment method can be adopted to ensure that the terminal attempts to access in each 8M uplink sub-bandwidth, and the access failure will not be caused by large interference.

[0078] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0079] Figure 5 This is a schematic diagram of the random access resource allocation method provided in the embodiment of the present application. Figure 1 ,like Figure 5 As shown, the random access resource allocation method includes:

[0080] Step 501: The network device sends first configuration information, and the terminal receives the first configuration information, wherein the first configuration information is used to configure the RO; wherein the RO configured by the first configuration information satisfies at least one of the following characteristics: there is a specific interval between the ROs in the frequency domain; there is a specific association relationship between the RO and the SSB, and the specific association relationship means that the RO is associated with each SSB in the SSB cycle in a specific order, wherein the SSB cycle includes multiple SSBs, and the starting SSB in the SSB cycle is configurable.

[0081] In the embodiment of the present application, the network device may be a base station.

[0082] In an embodiment of the present application, the first configuration information is carried in a system broadcast message, where the system broadcast message may be SIB1, for example.

[0083] In the embodiment of the present application, the RO configured by the first configuration information satisfies at least one of the following characteristics:

[0084] Feature A: There is a specific interval between ROs in the frequency domain;

[0085] Feature B: There is a specific association relationship between RO and SSB, and the specific association relationship means that RO is associated with each SSB in the SSB cycle in a specific order, wherein the SSB cycle includes multiple SSBs, and the starting SSB in the SSB cycle is configurable.

[0086] The above-mentioned feature A and feature B are described in detail below.

[0087] Feature A

[0088] In the embodiment of the present application, there is a specific interval between ROs in the frequency domain.

[0089] As an implementation manner, the ROs have a specific interval in the frequency domain, which means that two adjacent ROs are spaced apart by N physical resource blocks PRBs in the frequency domain, where N is a positive integer.

[0090] In a specific implementation, the first configuration information includes first information, and the first information is used to configure the number of ROs in the frequency domain to be M, where M is a positive integer; wherein the first information is also used to configure the number of PRBs between two adjacent ROs in the M ROs to be N. Here, as an example, the first information can be implemented by extending the meaning of the parameter MSG1-FDM, specifically, MSG1-FDM is not only used to configure the number of ROs in the frequency domain to be M, but also used to configure the number of PRBs between two adjacent ROs in the M ROs to be N.

[0091] As another implementation, the ROs have a specific interval in the frequency domain, which means that two adjacent RO groups are spaced N PRBs apart in the frequency domain, wherein each RO group includes M ROs, and the M ROs are continuously distributed in the frequency domain, and N and M are positive integers. Here, the P RO groups are repeated RO groups.

[0092] In specific implementation, the first configuration information includes second information, and the second information is used to configure the number of ROs included in each RO group to be M; wherein the second information is also used to configure the number of RO groups in the frequency domain to be P, and the number of PRBs between two adjacent RO groups in the P RO groups to be N, where P is a positive integer. Here, as an example, the second information can be implemented by extending the meaning of the parameter MSG1-FDM. Specifically, MSG1-FDM is not only used to configure the number of ROs in the frequency domain to be M, but also to configure the number of repetitions of the M ROs to be P, and also to configure the number of PRBs between each M RO to be N. It should be noted that M ROs can be called an RO group.

[0093] Feature B

[0094] In an embodiment of the present application, there is a specific association relationship between RO and SSB, and the specific association relationship means that RO is associated with each SSB in the SSB cycle in a specific order, wherein the SSB cycle includes multiple SSBs, and the starting SSB in the SSB cycle is configurable.

[0095] Here, the RO is associated with each SSB in the SSB cycle in a specific order, which means that the RO is associated with each SSB in the SSB cycle in an order from low to high in the frequency domain and then in an order from small to large in the time domain.

[0096] In a specific implementation, the first configuration information includes third information, and the third information is used to configure the number of SSBs associated with an RO; wherein the third information is also used to configure the starting SSB of each SSB cycle in one or more consecutive SSB cycles.

[0097] In the embodiment of the present application, after the terminal obtains the first configuration information, it selects an RO based on the first configuration information and initiates random access based on the selected RO. Here, since the RO configured by the first configuration information distributes the full bandwidth, the terminal can attempt to access the full bandwidth, avoiding access failure caused by excessive interference at a fixed location, and wasting other uplink low-interference resources.

[0098] The technical solution of the embodiment of the present application can achieve the distribution of PRACH resources (i.e., RO) across the full bandwidth by extending the meaning of the parameter MSG1-FDM and combining the meaning of the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB, so that the terminal can attempt to access at the full bandwidth, avoiding access failure caused by excessive interference at a fixed location and wasting other uplink low-interference resources.

[0099] Figure 6 This is a schematic diagram of the random access resource allocation method provided in the embodiment of the present application. Figure 2 ,like Figure 6 As shown, the random access resource allocation method includes:

[0100] Step 601: The network device sends second configuration information, and the terminal receives the second configuration information, where the second configuration information is used to configure frequency hopping information of the RO; wherein the frequency hopping information is used by the terminal to adjust the frequency domain resources of the RO used when initiating random access.

[0101] In the embodiment of the present application, the network device may be a base station.

[0102] In the embodiment of the present application, the second configuration information can be implemented through the information element RACH-ConfigGeneric in the RRC signaling.

[0103] As an implementation manner, the second configuration information includes fourth information, and the fourth information is used to configure the frequency hopping information of the RO to be L PRBs, where L is a positive integer.

[0104] In an embodiment of the present application, after the terminal fails to initiate random access using the first RO, it re-initiates random access using the second RO, wherein the second RO and the first RO use the same time domain resources, and the frequency domain resources of the second RO are determined based on the frequency domain resources of the first RO and the frequency hopping information.

[0105] In the above scheme, the value of L can be configured according to the interference law, which can be dense or sparse. Dense configuration leads to large PRACH resource overhead, and sparse configuration leads to long terminal access delay. The network side can optimize the configuration of this parameter based on the existing network.

[0106] Further, in some optional implementations, the network device sends third configuration information, and the terminal receives the third configuration information, and the third configuration information is used to configure PUCCH; wherein the frequency domain resources of the PUCCH are the same as the frequency domain resources of the RO used when the terminal successfully performs random access. The terminal sends an SRS after entering the connected state, wherein the SRS is used by the network side to update the initial RO of random access and the frequency hopping information. Accordingly, the network device receives the SRS sent by the terminal, and updates the initial RO of random access and the frequency hopping information based on the detection result of the SRS.

[0107] The technical solution of the embodiment of the present application ensures that the terminal accesses different ROs in a random access process by adjusting the frequency domain position of each RO hop in the random access process.

[0108] The technical solution of the embodiment of the present application is illustrated below in combination with specific application strength.

[0109] Application Example 1

[0110] Solution 1) Configure RO interval

[0111] Option a) If Figure 7 As shown, the parameter MSG1-FDM is used to configure 4 ROs in the frequency domain, and N PRBs are spaced between two adjacent ROs.

[0112] Option b) If Figure 8 As shown, the parameter MSG1-FDM is used to configure 4 consecutive ROs in the frequency domain, and the 4 consecutive ROs are repeated twice in the frequency domain, and N PRBs are spaced between consecutive ROs.

[0113] Solution 2) Configure the starting SSB in each SSB cycle

[0114] like Fig. 9 As shown, the RO is associated with each SSB in the SSB cycle in the order of frequency domain from low to high and then time domain from small to large. The starting SSB of each SSB cycle is configurable. Fig. 9 4 SSB cycles are shown in FIG. 1 , and the starting SSBs of the 4 SSB cycles are configured as SSB0, SSB2, and SSB4, respectively. In this way, the starting positions of the RO are deployed throughout the frequency domain.

[0115] Application Example 2

[0116] The terminal selects the time domain resources for random access (such as random access period, random access time slot) according to the parameter prach-ConfigurationIndex, and the terminal selects the frequency resources for random access according to the parameters MSG1-FDM and MSG1-FrequencyStart. The time and frequency resources for random access are also PRACH resources (also known as RO), and the frequency domain resources of adjacent ROs in the frequency domain are continuously distributed.

[0117] The base station configures the frequency hopping information of the RO through the information element RACH-ConfigGeneric carried in the RRC signaling. As an example, the frequency hopping information is, for example, MSG1-hop=L, where L represents the number of PRBs, such as 44 PRBs in an 8 MHz bandwidth.

[0118] When implementing it specifically, Fig.10 As shown, after the terminal uses the PRACH resource to initiate random access (i.e., send a preamble), if it does not receive a PRACH response (i.e., RAR) within the time specified by the ra-ResponseWindow, it will initiate random access again. Compared with the PRACH resource used previously, the PRACH resource used by the terminal to initiate random access again has the same time domain resource, and the frequency domain resource hops to the frequency domain resource position of L PRBs after the frequency domain resource corresponding to the previously used PRACH resource.

[0119] Here, when the terminal fails in random access, the next time it re-initiates random access, the PRACH resources used are compared with the previously used PRACH resources. The time domain resources remain unchanged, and the frequency domain resources hop. If multiple random accesses cause the frequency hopping to exceed the full bandwidth, the terminal will initiate random access from the initial access time and frequency domain.

[0120] In the above scheme, the value of L can be configured according to the interference law, which can be dense or sparse. Dense configuration leads to large PRACH resource overhead, and sparse configuration leads to long terminal access delay. The network side can optimize the configuration of this parameter based on the existing network.

[0121] Further, the base station configures PUCCH resources for the terminal based on the PRACH resources used when the terminal successfully accesses, wherein the PUCCH resources and the PRACH resources used when the terminal successfully accesses have the same frequency domain position. Further, after the terminal enters the connected state, it reports the SRS, and the base station determines the interference situation according to the SRS report, and adjusts the PUCCH resources and PRACH resources according to the interference situation, for example, adjusting the initial position of the PRACH resources and the frequency hopping information P, to ensure the continuity of the terminal uplink service.

[0122] The technical solution of the embodiment of the present application, on the one hand, makes the location of PRACH resources distributed in the full bandwidth frequency domain to ensure normal access of the terminal. Specifically, a new RO distribution method is added, including adjacent RO interval PRB deployment and adjacent RO group interval PRB deployment; in the association relationship between SSB and RO, the starting SSB in the cyclic SSB is set so that the same SSB corresponds to different ROs. On the other hand, the frequency hopping information of the new RO is added. After a random access fails, when the terminal accesses the same time domain resource, the frequency domain hopping is performed to meet the full bandwidth access attempt and avoid large interference and inability to access. The base station configures PRACH resources with full bandwidth and receives terminal access information for each PRACH resource. After the base station successfully receives the PRACH of the terminal, the PUCCH of the terminal is configured to have the same frequency domain as the PRACH, for example, the PUCCH-ConfigCommon is configured with the same frequency domain position as the PRACH resource, to ensure that the data is turned on normally after the terminal accesses. After the terminal enters the connected state, the base station can update the PRACH initial access resources and frequency hopping information according to the SRS reported by the terminal.
