Description

Technical Field

[0001] The present invention relates to the field of wireless technologies, and in particular, to a configuration method, apparatus, terminal, and network device. Background Art

[0002] In a large-capacity scenario, due to the access of a large number of users, a large amount of control channel resources need to be occupied. Moreover, when the number of users increases, the interference rise will lead to an increase in the number of reconstructions / retransmissions, and a large amount of control resources also need to be consumed, making it extremely easy to have insufficient control channel resources, especially in the case of limited resources of the common Physical Downlink Control Channel (common PDCCH).

[0003] Currently, the large-capacity scenario is mainly limited by the resources of the common PDCCH. Therefore, it is crucial to increase the resources of the common PDCCH. Existing guarantee solutions deploy more cells to meet the needs of a large number of users. However, when the number of idle-state users is small, deploying too many cells will waste resources. Moreover, in most scenarios, the installation conditions are limited and do not support the deployment of too many hardware devices. Summary of the Invention

[0076] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0077] To solve the problem that when a large number of users access, the common PDCCH resources are insufficient, increasing the number of deployed cells to improve the common PDCCH resources, and there is also the problem of resource waste when idle, the embodiment of the present invention provides a configuration method, which dynamically adjusts the number of CD-SSBs to meet the provision of common PDCCH resources when a large number of users access, and avoids the problem of resource waste when idle.

[0078] Combined with Figure 1As shown, the configuration method according to the embodiments of the present invention supports configuring multiple Synchronization Signal and PBCH blocks (SSBs), so as to be able to increase the accessed common PDCCH resources and improve the number of admitted users on the carrier. In addition, among the multiple configured SSBs, at least two SSBs are associated with SIB1 (Remaining Minimum System Information (RMSI)), which are called Cell Defining-SSBs (CD-SSBs) and are used for terminal access. Among the multiple configured SSBs, the SSBs not associated with the system information block SIB1 (RMSI) cannot be used for terminal access, but can be used for terminal measurement. For example, Figure 1 in Figure 1 , SSB1 and SSB3 are associated with SIB1 and are called CD-SSBs for terminal access; SSB2 and SSB4 are not associated with SIB1 and cannot be used for terminal access.

[0079] According to the above, in the embodiments of the present invention, among the multiple SSBs configured by the network device, when an SSB is associated with SIB1 (RMSI), the SSB can be called a CD-SSB.

[0080] Figure 2 FIG. is a schematic structural diagram of one embodiment of the configuration method of the present invention. In this embodiment, the configuration method is executed by a network device and includes:

[0081] S210, when the current network state meets the first condition, adjust the first number of Cell Defining-SSBs (CD-SSBs) configured for the terminal to configure the second number of CD-SSBs; the second number is different from the first number;

[0082] S220, send an access message to the terminal on a target CD-SSB among the second number of CD-SSBs.

[0083] Adopting the configuration method described in this embodiment, it is possible to judge whether the first condition is met based on the network state and start the adjustment of the number configuration of CD-SSBs, so that when a large number of users access and the common PDCCH resources are insufficient, by adjusting the number of CD-SSBs, the common PDCCH resources can be increased; and when the network is idle, the adjusted number of CD-SSBs can avoid the problem of resource waste.

[0084] In one implementation, the first condition is a condition for judging whether the common PDCCH resources can support the current large number of user accesses in the case of a large number of user accesses.

[0085] In this embodiment, the second quantity is greater than the first quantity;

[0086] When the network status meets the first condition, the first quantity of cell-defined synchronization signal blocks (CD-SSBs) configured for the terminal is adjusted to configure a second quantity of CD-SSBs, where the second quantity is greater than the first quantity, thereby increasing the quantity of configured CD-SSBs.

[0087] Among them, the first condition includes one or more of the following:

[0088] The number of Radio Resource Control (RRC) connected users is greater than a first threshold;

[0089] The allocation success rate of uplink control channel elements (CCEs) is less than a second threshold;

[0090] The allocation success rate of downlink CCEs is less than a third threshold;

[0091] The utilization rate of uplink CCEs is greater than a fourth threshold;

[0092] The utilization rate of downlink CCEs is greater than a fifth threshold.

[0093] Optionally, the above-mentioned first threshold, second threshold, third threshold, fourth threshold, and fifth threshold can be set according to network requirements respectively.

[0094] Optionally, the second quantity is greater than or equal to 2.

[0095] In one embodiment, optionally, when the network device determines that the current number of RRC connected users is greater than the first threshold, it further determines whether at least one of the above conditions is met. When it is determined that at least one of the above conditions is met, the first quantity of CD-SSBs configured for the terminal is adjusted to configure a second quantity of CD-SSBs, thereby increasing the quantity of configured CD-SSBs.

[0096] For the specific implementation process of this embodiment, reference can be made to Figure 3 As shown, it includes the following steps:

[0097] S301, count the current number of RRC connected users, the allocation success rates of uplink and downlink CCEs, and the utilization rates of uplink and downlink CCEs;

[0098] S302, determine whether the current number of RRC connected users is greater than the first threshold; if the determination result is yes, execute step S303; if the determination result is no, return to execute step S301;

[0099] S303, determine whether the following conditions are met:

[0100] The success rate of uplink control channel unit CCE allocation is less than the second threshold;

[0101] The success rate of downlink CCE allocation is less than the third threshold;

[0102] The utilization rate of uplink CCE is greater than the fourth threshold;

[0103] The utilization rate of downlink CCE is greater than the fifth threshold;

[0104] According to the preset first condition, the above conditions to be met can include one or more; when the above conditions are one and it is determined that the current network meets any one of the above conditions, then execute step S304; when the above conditions include 2, 3, or 4 and it is determined that the current network meets the set number of the above conditions, then execute step S304, otherwise return to execute step S301;

[0105] S304, adjust the number of CD-SSBs configured for the terminal; that is, adjust the first number of cell-defined synchronization signal blocks CD-SSBs configured for the terminal to the second number of CD-SSBs, where the second number is greater than the first number, increasing the number of configured CD-SSBs; then, return to step S301 and continue to count the current number of RRC connected users, the success rates of uplink and downlink CCE allocations, and the utilization rates of uplink and downlink CCEs.

[0106] Adopting this implementation method, it is possible to start the adjustment of the CD-SSB number configuration based on the network status when the current number of RRC connected users is greater than the first threshold and meets any of the above conditions, so that when a large number of users access and the common PDCCH resources are insufficient, by increasing the number of CD-SSBs, the common PDCCH resources can be increased.

[0107] In another implementation method, the first condition is a condition for determining whether there is resource waste when the current network is idle.

[0108] In this implementation method, the second number is less than the first number;

[0109] Among them, the first condition includes one or more of the following:

[0110] The number of RRC connected users is less than the sixth threshold;

[0111] The success rate of uplink control channel unit CCE allocation is greater than the seventh threshold;

[0112] The success rate of downlink CCE allocation is greater than the eighth threshold;

[0113] The uplink CCE utilization rate is less than the ninth threshold;

[0114] The downlink CCE utilization rate is less than the tenth threshold.

[0115] Optionally, the above sixth threshold, seventh threshold, eighth threshold, ninth threshold, and tenth threshold can be set according to network requirements respectively.

[0116] Optionally, in this embodiment, when the network state satisfies the first condition, the first number of cell-defined synchronization signal blocks CD-SSBs configured for the terminal is adjusted to configure the second number of CD-SSBs, and the second number is less than the first number, reducing the number of configured CD-SSBs.

[0117] Optionally, the minimum value of the second number is 1.

[0118] In one embodiment, optionally, when the network device determines that the current number of RRC-connected users is less than the sixth threshold, it further determines whether at least one of the above conditions is satisfied. When it is determined that at least one of the above conditions is satisfied, the first number of CD-SSBs configured for the terminal is adjusted to configure the second number of CD-SSBs, reducing the number of configured CD-SSBs.

[0119] For the specific implementation process of this embodiment, reference can be made to Figure 4 as shown, including the following steps:

[0120] S401, count the current number of RRC-connected users, the success rates of uplink and downlink CCE allocations, and the uplink and downlink CCE utilization rates;

[0121] S402, determine whether the current number of RRC-connected users is less than the sixth threshold; if the determination result is yes, execute step S403; if the determination result is no, return to execute step S401;

[0122] S403, determine whether the following conditions are satisfied:

[0123] The success rate of uplink control channel element CCE allocation is greater than the seventh threshold;

[0124] The downlink CCE allocation success rate is greater than the eighth threshold;

[0125] The uplink CCE utilization rate is less than the ninth threshold;

[0126] The downlink CCE utilization rate is less than the tenth threshold.

[0127] According to the preset first condition, the above conditions to be satisfied may include one or multiple; when the above condition is one and it is determined that the current network satisfies any one of the above conditions, step S404 is executed; when the above conditions include two, three, or four and it is determined that the current network satisfies the set number of the above conditions, step S404 is executed, otherwise, return to execute step S401;

[0128] S404, adjust the number of CD-SSBs configured for the terminal; that is, define the first number of cell-defined synchronization signal blocks CD-SSBs configured for the terminal as the second number of CD-SSBs, where the second number is less than the first number, reducing the number of configured CD-SSBs. After that, return to step S401 and continue to count the current number of RRC-connected users, the success rates of uplink and downlink CCE allocations, and the uplink and downlink CCE utilization rates.

[0129] Adopting this embodiment, it is possible to start the adjustment of the CD-SSB number configuration based on the network status when the current number of RRC-connected users is less than the sixth threshold and satisfies any of the above conditions, so that when the network is in the idle state and the number of RRC-connected users is less than the sixth threshold, by reducing the number of CD-SSBs, the common PDCCH resources are reduced to avoid resource waste.

[0130] In one embodiment of the present invention, after the network device adjusts the number of CD-SSBs configured for the terminal, for example, after increasing the number of configured CD-SSBs, it sends an indication message (the first message) to the terminal to indicate the target CD-SSB to which the terminal is connected.

[0131] In one embodiment, optionally, the first message includes the SIB1 message;

[0132] The Kssb value in the SIB1 message is a preset value, which is used to indicate that the target CD-SSB is the position of the next CD-SSB among the CD-SSBs currently accessed by the terminal.

[0133] Specifically, the Kssb value in the SIB1 message is a preset value, which is used to indicate that the terminal cannot access the current CD-SSB and needs to access the next CD-SSB.

[0134] In an embodiment of the present invention, optionally, the preset value is 30. When the Kssb value in the SIB1 message sent by the network device is 30, it is used to indicate that the terminal cannot access the current CD-SSB and needs to access the next CD-SSB.

[0135] Taking FR1 as an example, the protocol defines the value range of Kssb. FR1 Kssb is indicated by 5 bits. When the sub-carrier spacing (SCS) of the common resource block (CRB) is 30 kHz, the position range of SSB sc0 in this CRB is represented by 0 to 23; when the CRB SCS is 15 kHz, the position range of SSB sc0 in this CRB is represented by 0 to 11. As shown in Table 1 below, when FR1-kssb takes values from 24 to 29, a value mapping can be calculated according to the control resource set zero (controlResourceSetZero) and the search space zero (searchSpaceZero). (used to indicate the offset of the global synchronization channel number (GSCN) of the second SSB from the GSCN of the first SSB); when FR1-kssb takes the value of 30, it is a reserved bit in the protocol, and in the embodiments of the present invention, it is used to indicate that the terminal's current CD-SSB cannot be accessed and needs to access the next CD-SSB.

[0136] Table 1

[0137]

[0138] In the embodiments of the present invention, optionally, the terminal can determine the corresponding value of the target CD-SSB it accesses according to one of the following methods

[0139] The value of is the value determined according to (-768, 768) mod 4;

[0140] The value of is the corresponding value when Kssb is any one of 24 to 29 value.

[0141] In another implementation manner, optionally, the network device configures multiple Kssbs to indicate the positions of multiple CD-SSBs, so that the terminal determines the target CD-SSB it accesses by demodulating the random access response (RAR) message.

[0142] In this implementation manner, the method further includes:

[0143] Sending a second message to the terminal, where the second message is used to instruct the terminal to determine the accessed target CD-SSB by demodulating the received RAR.

[0144] Optionally, the second message includes an SIB1 message, and the SIB1 message includes at least two Kssb values, each Kssb value correspondingly indicating the position of a CD-SSB.

[0145] Specifically, the network device configures multiple CD-SSBs through frequency division within a carrier frequency band. The CD-SSBs are associated with the same SIB1. During cell search and synchronization, the terminal will select an SSB with the strongest signal. For example, Figure 5 as shown, the access process of terminal 1 includes the following steps:

[0146] During the synchronization process of terminal 1, it selects CD-SSB2 (i.e., beam 2) for access. The network device sends an SIB1 message to the terminal on CD-SSB2 to obtain the RAR-PDCCH configuration;

[0147] Since the terminal detects beam 2, during the random access process, it initiates a random access request on CD-SSB2 (i.e., beam 2);

[0148] The network device determines on which CD-SSB to reply to the received random access request according to the number of users on each CD-SSB. If the number of users on CD-SSB2 is greater than a set threshold (such as the first threshold) at this time, while the number of users on CD-SSB3 is less than the set threshold (such as the sixth threshold), it selects to reply to the terminal's random access response on CD-SSB3;

[0149] Furthermore, the terminal will demodulate the random access response with RA-RNTI. If it demodulates its own message, it will perform subsequent RRC connection establishment and initiate services on the corresponding CD-SSB.

[0150] It should be noted that in this implementation process, different beams represent different CD-SSBs, rather than indicating different direction scans.

[0151] By using the method described in the embodiments of the present invention, after the network device configures multiple CD-SSBs, it determines the target CD-SSB to which the terminal is connected during the access process according to the number of users accessing each CD-SSB, so as to ensure that a large number of users are evenly accessed to each CD-SSB (beam), and avoid resource congestion caused by concentration on the same CD-SSB (beam).

[0152] In the embodiments of the present invention, optionally, when adjusting the first number of cell-defined synchronization signal blocks CD-SSBs configured for the terminal to the second number of CD-SSBs, the method further includes:

[0153] When configuring the second number of CD-SSBs, each of the CD-SSBs corresponds to the same cell ID.

[0154] In the embodiments of the present invention, each of the multiple CD-SSBs corresponds to the same cell ID. In this way, only the number of CD-SSBs is increased. Multiple cells can be regarded as a logical cell, but no additional hardware resources are required. For access, it can be performed on multiple CD-SSBs. When performing service data transmission, the resources of one carrier can be used for unified scheduling.

[0155] Another embodiment of the present invention further provides a configuration method, which is executed by a terminal, as Figure 6 shown, the method includes:

[0156] S601, determining a target cell-defined synchronization signal block CD-SSB for receiving an access message sent by a network device; wherein, the target CD-SSB is one of the second number of CD-SSBs; the second number is obtained by the network device adjusting the first number of CD-SSBs to be configured for the terminal to configure the second number of CD-SSBs when the first condition is currently satisfied;

[0157] S602, receiving the access message on the target CD-SSB.

[0158] By adopting the configuration method described in the embodiments of the present invention, by dynamically adjusting the number of CD-SSBs by the network device, it is possible to meet the provision of common PDCCH resources when a large number of users access, and avoid the problem of resource waste when there is idle time.

[0159] Optionally, in the configuration method, the method further includes:

[0160] Receiving a first message sent by the network device, where the first message is used to indicate the target CD-SSB accessed by the terminal;

[0161] Wherein, determining the target CD-SSB includes:

[0162] Determining the target CD-SSB according to the first message.

[0163] Optionally, in the configuration method, the first message includes an SIB1 message;

[0164] The Kssb value in the SIB1 message is a preset value, which is used to indicate that the target CD-SSB is the position of the next CD-SSB among the CD-SSBs currently accessed by the terminal.

[0165] Optionally, in the configuration method, the method further includes:

[0166] Receive a second message sent by the network device, where the second message is used to instruct the terminal to determine the target CD-SSB it accesses by demodulating the received random access response (RAR).

[0167] Among them, determining the target CD-SSB includes:

[0168] When demodulating the random access response sent by the network device after sending an access request to the network device, determine the target CD-SSB that is accessed.

[0169] Optionally, for the configuration method described above, the method further includes:

[0170] Send an access request to the network device on a first CD-SSB;

[0171] Among them, the target CD-SSB is the CD-SSB other than the first CD-SSB among the second quantity of CD-SSBs.

[0172] The specific implementation of the configuration method described in the embodiments of the present invention applied to the terminal side can be combined with Figures 1 to 5 the detailed description of the specific implementation applied to the network device, and will not be repeated here.

[0173] One embodiment of the present invention further provides a network device, as Figure 7 shown. This network device 700 includes a processor 710 and a transceiver 720, where:
