Description

Technical Field

[0001] This application relates to the field of wireless communication technology, such as an information determination method, communication node, system, and storage medium. Background Technology

[0002] In existing communication systems, a terminal selects a synchronization signal within a cell, obtains an access signal resource pool based on the selected synchronization signal, chooses an access signal resource from this pool, and transmits an access signal on that resource. One access signal resource pool corresponds to one synchronization signal within a cell. After receiving the access signal from the terminal, the access point (AP) only knows that the terminal is within the coverage area of ​​the selected synchronization signal, but it doesn't know its reception performance on other synchronization signals. This prevents the base station from acquiring more information in a timely manner during the initial access phase, resulting in the inability to use better spatial transmission beams and poor inter-cell interference management, leading to frequent cell handovers and low spectral efficiency during the initial access phase. Furthermore, current technologies configure parameters at the cell or synchronization signal level, making parameter adjustments for users at the cell edge cumbersome and delayed. This problem becomes increasingly prominent as cells become denser. In multi-node scenarios, how to obtain uplink access signal resources based on the synchronization signals of multiple nodes, the management and configuration of parameters in multiple node systems, the management and configuration of system messages, and the division and management of regions have become urgent problems to be solved.

Furthermore, in multi-node systems, nodes are activated on demand, reducing the processing complexity of each node. Attached Figure Description

[0039] The present application will now be described in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present application are shown in the accompanying drawings, not the entire structure.

[0040] Figure 1 This is a schematic diagram illustrating a multi-node synchronization signal transmission scheme, where each synchronization signal corresponds to a separate PRACH resource pool, as provided in one embodiment. Figure 1 As shown, each AP corresponds to one cell. Each cell transmits synchronization signals using different transmit beams on two time-division synchronization signal resources. Each synchronization signal in each cell corresponds to an access signal resource pool. The terminal selects a synchronization signal based on its reception performance, determines the access signal resource pool based on the selected synchronization signal, selects an access signal resource from the access signal resource pool, and transmits the access signal on the selected access signal resource. After receiving the access signal transmitted by the terminal, the access point only knows that the terminal is located within the coverage area of ​​the selected synchronization signal, but does not know its reception performance on other synchronization signals. For example, if the terminal selects SS0 of AP0, the base station, after receiving the access signal, only knows that the terminal is under the coverage of beam 11, but does not know other information. Therefore, the base station cannot obtain more information in a timely manner during the initial access phase, resulting in the inability to use better spatial transmit beams for communication with the terminal during the initial access phase. Inter-cell interference cannot be well managed, and cell handover is frequent, resulting in low spectral efficiency during the initial access phase. Figure 1 In this context, the synchronization signals of different APs can be distinguished by code division. For example, the synchronization signals (Synchronization Signal, SS) of the same index of different APs correspond to different sequences. Of course, it is also possible that the synchronization signals of different APs can be distinguished by time division or frequency division.

[0127] Among the P synchronization signals, at least one synchronization signal exists, and the at least one synchronization signal belongs to at least two of the X synchronization signal groups.

[0128] In one embodiment, there are multiple second communication nodes; each of the P synchronization signals is sent by some or all of the multiple second communication nodes.

[0129] Each of the multiple second communication nodes is determined to correspond to at least one synchronization signal and A groups of synchronization signals, wherein the value of A corresponding to different second communication nodes may be the same or different.

[0130] The following examples illustrate the information determination method of this application.

[0131] In one embodiment, a first communication node (hereinafter, a terminal, is used as an example) determines X synchronization signal groups, and within these X synchronization signal groups, Y target synchronization signal groups are determined. The determined target synchronization signal group determination information includes one of the following: parameter information of the target signal, or control signaling information. Wherein, X is a positive integer greater than or equal to 1. Y is a positive integer less than or equal to X. The X synchronization signal groups include at least one first-type synchronization signal group, and each first-type synchronization signal group includes at least two synchronization signals. As an example, Y = 1.

[0132] In one example, the terminal determines Y target synchronization signal groups from the X synchronization signal groups based on the measurement results of the synchronization signals and at least one of the following: predetermined rules, predetermined characteristics, and the number of synchronization signals included in the synchronization signal groups.

[0133] In one example, the predetermined feature is a feature satisfied by the measurement results of the synchronization signals in the target synchronization signal group.

[0134] In one example, the predefined rules include at least one of the following:

[0135] Rule 1: Each of the Y target synchronization signal groups satisfies the predetermined characteristics;

[0136] Rule 2: If none of the X synchronization signal groups satisfy the predetermined characteristics, Y synchronization signal groups shall be randomly selected from the X synchronization signal groups as target synchronization signal groups.

[0137] Rule 3: If more than Y synchronization signal groups satisfy the predetermined characteristics, the Y synchronization signal groups are determined as target synchronization signal groups according to the number of synchronization signals included in each synchronization signal group. For example, synchronization signal groups that include more synchronization signals are preferentially selected.

[0138] Rule 4: The predetermined features include multiple predetermined features, such as a first predetermined feature and a second predetermined feature. From X groups of synchronization signals, a synchronization signal group is determined based on the first predetermined feature. If the number of determined synchronization signal groups is greater than the Y value, a synchronization signal group is then selected from the determined synchronization signal groups based on the second predetermined feature. This process can be repeated when more than two predetermined features are involved. For example, the first predetermined feature is that the measurement result of each synchronization signal in the synchronization signal group is greater than a first predetermined value. Based on the first predetermined feature, more than Y synchronization signal groups satisfy the first predetermined feature. Then, based on the second predetermined feature, Y target synchronization signal groups are selected from the more than Y obtained synchronization signal groups, prioritizing those with the largest number of synchronization signals.

[0139] In one example, the predetermined feature includes at least one of the following:

[0140] The measurement result of each synchronization signal in the synchronization signal group is greater than a first predetermined value;

[0141] The difference between the measurement results of different synchronization signals in the synchronization signal group is less than a second predetermined value;

[0142] The sum of the measurement results of the synchronization signals in the synchronization signal group is greater than a third predetermined value;

[0143] The measurement results obtained based on all synchronization signals in the synchronization signal group meet predetermined characteristics.

[0144] In one example, the first predetermined value and the third predetermined value are the same value. In another example, the first predetermined value and the third predetermined value are different values. Measurement results obtained based on all synchronization signals in the synchronization signal group satisfying predetermined characteristics indicate that a channel is obtained based on the synchronization signals in the synchronization signal group. This channel is the number of receiving antennas multiplied by the number of synchronization signals, where the number of synchronization signals is the number of synchronization signals included in this synchronization signal group. The measurement result obtained based on this channel is the measurement result obtained based on all synchronization signals in the synchronization signal group; that is, different synchronization signals in the synchronization signal group are considered as different measurement reference signal ports of the base station. And / or measurement results obtained based on all synchronization signals in the synchronization signal group satisfying predetermined characteristics indicate that: a measurement result is obtained based on each synchronization signal in the synchronization signal group, multiple synchronization signals in the synchronization signal group correspond to multiple measurement results, and the multiple measurement results satisfy predetermined characteristics, such as the distribution of the multiple measurement results satisfying predetermined characteristics, or the combination of multiple measurement results satisfying predetermined characteristics.

[0145] In one example, the measurement result of the synchronization signal includes at least one of the following: (Reference Signal Receiving Power), Signal-to-Interference-plus-Noise Ratio (SINR), and large-scale channel parameters. The large-scale channel parameters include at least one of the following: Doppler shift, Doppler spread, Average Delay, and Delay Spread. When the measurement result is Doppler spread, the synchronization signal group with the smallest corresponding Doppler spread is preferentially selected, so that when the base station subsequently uses the spatial beam combination corresponding to the synchronization signals in this synchronization signal group to transmit signals to the terminal, the channel changes slowly in the time domain. When the measurement result is delay spread, the synchronization signal group with the smallest corresponding delay spread is preferentially selected, so that when the base station subsequently uses the spatial beam combination corresponding to the synchronization signals in this synchronization signal group to transmit signals to the terminal, the channel changes slowly in the frequency domain.

[0146] In one example, determining the information based on the target synchronization signal group includes determining the information based on at least one of the following: the target synchronization signal group, the type of the target synchronization signal group, and the set of synchronization signals to which the synchronization signals in the synchronization signal group belong. The information includes at least one of a first type of information, a second type of information, a third type of information, a fourth type of information, and a fifth type of information. Different synchronization signal groups among the X synchronization signal groups each correspond to a set of values ​​for the first type of information. Preferably, different synchronization signal groups among the X synchronization signal groups correspond to different values ​​for the first type of information. Different types of synchronization signal groups each correspond to a set of values ​​for the second type of information; preferably, the values ​​for the second type of information corresponding to the different types of synchronization signal groups are different. Alternatively, the synchronization signal set and the synchronization signal group set can be considered as different types of synchronization signal groups, for example, the type of a synchronization signal group can be determined based on at least one of the following: the number of synchronization signals included in the synchronization signal group, the number of subgroups included in the synchronization signal group, and the number of sequences corresponding to the synchronization signals included in the synchronization signal group.

[0147] In one example, the type of synchronization signal group is determined by the number of synchronization signals it contains. For instance, a synchronization signal group containing more than one synchronization signal is classified as a first-type synchronization signal group, and a synchronization signal group containing one synchronization signal is classified as a second-type synchronization signal group. Alternatively, the first-type synchronization signal group can be further divided into multiple subtypes. For example, a synchronization signal group containing two synchronization signals is classified as a first-type synchronization signal group (also known as the first subclass of the first type), a synchronization signal group containing one synchronization signal is classified as a second-type synchronization signal group, and a synchronization signal group containing more than two synchronization signals is classified as a third-type synchronization signal group (also known as the second subclass of the first type). Synchronization signal groups of the same type correspond to the same value of the second-type information. In one example, the same synchronization signal group corresponds to the same first-type information.

[0148] In one example, the X synchronization signal groups belong to Z synchronization signal sets, where each synchronization signal set includes one or more synchronization signals. The synchronization signals in a synchronization signal group can originate from different synchronization signal sets within the Z synchronization signal sets. Preferably, the synchronization signals in a synchronization signal set are transmitted by the same transmitting node, and / or the synchronization signals in a synchronization signal set correspond to at least one of the following: code domain index, frequency domain resource index, and time domain resource index. Z is a positive integer greater than or equal to 1. A synchronization signal set includes synchronization signals from one or more synchronization signal groups.

[0149] In one example, determining the information based on the target signal group includes: determining the third type of information based on the set of synchronization signals to which the target signal group belongs. Further, when the target signal group belongs to a predetermined type, the third type of information is determined based on the set of synchronization signals to which the target signal group belongs. When the target signal group does not belong to a predetermined type, the third type of information is determined based on the target signal group.

[0150] In one example, the number of synchronization signals included in the X synchronization signal groups can vary. For instance, some synchronization signal groups may contain only one synchronization signal, some may contain two synchronization signals, and some may contain three synchronization signals. For example, the X synchronization signal groups may include a first synchronization signal group to a third synchronization signal group, where the first synchronization signal group contains one synchronization signal, the second synchronization signal group contains two synchronization signals, and the third synchronization signal group contains three synchronization signals. At least one synchronization signal group of the first type exists among the X synchronization signal groups. This first type of synchronization signal group includes synchronization signal groups with more than one synchronization signal, such as the second and third synchronization signal groups mentioned above. The X synchronization signal groups may or may not include second type synchronization signal groups, where each second type synchronization signal group contains only one synchronization signal. For example, the three synchronization signal groups mentioned above include a second type synchronization signal group: the first synchronization signal group.

[0151] In one example, the X synchronization signal groups correspond to the same fourth type of information, such as at least one of the following: logical cell index, a serving cell index, a cell group index, a serving cell group index, PCI (Physical Cell Identifier), PCI group, broadcast message, frequency domain bandwidth index, and configuration unit index. In one example, the same synchronization signal may belong to more than one synchronization signal group. In one example, the number of synchronization signal groups to which the same synchronization signal can belong is less than a predetermined value, that is, there is a maximum value for the number of synchronization signal groups to which the same synchronization signal can belong. This maximum value can be reported by the terminal to the base station, or the base station can notify the terminal. For example, the X synchronization signal groups are located in one frequency domain bandwidth. The configuration unit index represents different configuration values ​​of the same parameter set configured for each configuration unit index; that is, the configuration unit index is a configuration index of a parameter set of the same type, preferably each configuration unit index corresponds to one frequency domain resource. Alternatively, each configuration unit index may correspond to a set of spatial domain resources, or each configuration unit index may correspond to a combination of spatial domain resources and frequency domain resources. For example, at least one of the spatial domain resources and frequency domain resources corresponding to different configuration units may be different.

[0152] In one example, different synchronization signals are distinguished by at least one of the following: the time-domain resources where the synchronization signal resides, the frequency-domain resources where the synchronization signal resides, the code-domain resources of the synchronization signal, and the spatial-domain resources of the synchronization signal. Two synchronization signals correspond to two groups (the time-domain resources where the synchronization signal resides, the frequency-domain resources where the synchronization signal resides, the code-domain resources of the synchronization signal, and the spatial-domain resources of the synchronization signal), each group including the above four resources. At least one of the four resources in the two groups corresponding to the two synchronization signals is different. That is, different synchronization signals correspond to at least one different resource among the above four resources.

[0153] In one example, the target signal includes one or more of uplink and downlink signals. For instance, the uplink signal includes at least one of the following: uplink access signal, uplink resource request signal, uplink control channel signal, uplink data channel signal, uplink measurement reference signal, and uplink reference signal. The downlink signal includes at least one of the following: downlink synchronization signal, downlink control channel signal, downlink measurement reference signal, downlink reference signal, common downlink signal, downlink data channel signal, downlink common control channel signal, and downlink common data channel signal.

[0154] In one example, the terminal transmits the target signal to the base station based on the parameters of the determined target signal (i.e., information of the target signal, where parameters are the information). The transmission includes at least one of the following: sending and receiving. For example, when the target signal is an uplink signal, the parameters of the target signal include at least one of the following: at least one of the time-frequency code resources for sending the uplink signal, the transmit beam for sending the uplink signal, and the power parameters for sending the uplink signal. When the target signal is a downlink signal, the parameters of the target signal include at least one of the following: at least one of the time-frequency resource codes for receiving the downlink signal, or a quasi-co-address reference signal for the downlink signal. When the target signal is a downlink control channel, the parameters of the target signal include at least one of the following: at least one of the detection time-frequency code resources for detecting the downlink control channel, or a quasi-co-address reference signal for the downlink control channel. When the parameters of the target signal include at least one of the time-frequency code resources of the target signal, the parameters include rate matching parameters, thereby enabling the terminal to determine the synchronization signal and PRACH signal for rate matching based on the region where the terminal is located.

[0155] Figure 4 This is a schematic diagram illustrating one embodiment of determining synchronization signal groups, with each synchronization signal group corresponding to a PRACH resource pool. For example... Figure 4As shown, when the terminal is located in region 5, the terminal determines synchronization signal group 5, and then determines the PRACH resource 5 corresponding to synchronization signal group 5. When determining the rate matching information of the target signal based on the synchronization signal group, when the terminal sends and receives the target signal, it only considers that at least one of the frequency domain resources and time domain resources occupied by the synchronization signal in synchronization signal group 5 cannot be occupied by the target signal. The target signal can occupy the synchronization signals in other synchronization signal groups for rate matching. Similarly, rate matching is only performed on the resources in PRACH resource 5, and rate matching is not performed on PRACH in other PRACH resource pools. For example, the target signal can only not occupy the resources in PRACH resource 5, but can occupy the resources in other PRACH resource pools.

[0156] In one example, the terminal performs corresponding operations based on determined control signaling information. These operations include at least one of the following: receiving a signal, sending a signal, updating a first-type message, initiating a process, such as initiating a cell handover process, and detecting a control channel. The control signaling information includes messages, which include at least one of the following: broadcast messages, system messages, and group messages. For example, messages corresponding to different areas may be different, or some messages corresponding to different areas may have the same content, but differ in at least one of the detection time-frequency code spatial resources. Here, a message can also be referred to as control signaling. The control signaling can also be control signaling that configures at least one of the following parameters: synchronization signal transmission parameters and PRACH parameters. For example, for each synchronization signal group (and / or each synchronization signal set), the transmission power of the synchronization signal is determined separately; the transmission power of the synchronization signal for different synchronization signal groups (and / or different synchronization signal sets) can be determined separately. Similarly, the PRACH parameters are determined separately for each synchronization signal group (and / or each synchronization signal set); the PRACH parameters for different synchronization signal groups (or different synchronization signal sets) can be determined separately. For example, the parameters of PRACH include the number of PRACH resources included in the PRACH resource pool. The number of users covered in different regions may be different, so different numbers of PRACH resources can be configured for different regions.

[0157] Specifically, such as Figure 4As shown, there are 3 access points (APs), each sending two synchronization signals. These two synchronization signals correspond to different transmission beams, covering different areas. For example, the j-th synchronization signal of APi is represented as SSij, where i = 1, 2, 3, j = 1, 2. A new area is formed in the region where the transmission beams of two different APs overlap. This area corresponds to the two synchronization signals from these two APs. For example, synchronization signal group 5 includes SS11 from AP1 and SS21 from AP2, corresponding to the overlapping area of ​​these two beams. Synchronization signal group 6 includes SS22 from AP2 and SS31 from AP3, also corresponding to the overlapping area of ​​these two beams. Different synchronization signal groups can correspond to different types of information, such as different access signal resource pools (PRACH resource pools).

[0158] Figure 5 This is a schematic diagram of a multi-node synchronization signal transmission system provided in one embodiment, in which each synchronization signal group corresponds to a user area. Figure 4 compared to Figure 5 The left-hand region division (i.e.) Figure 1 (the way of dividing), Figure 5 The right-hand area division (i.e.) Figure 4 The division method can achieve the regional division of synchronization signal groups. If the following method is adopted... Figure 5 In the left-hand approach, each synchronization signal constitutes a synchronization signal group, and each synchronization signal corresponds to a PRACH resource pool. Different synchronization signals within an AP correspond to different PRACH resource pools, and different synchronization signals in different APs can correspond to the same PRACH resource pool or different PRACH resource pools. Adjacent APs generally correspond to different PRACH resource pools. When a terminal (e.g., terminal 1) is located in area 5, terminal 1 selects either S11 or SS21. One problem is that terminal 1 will frequently switch between SS11 and SS21. Another problem is that AP1 and AP2 independently schedule resources. AP1 schedules terminal 2 under AP1 to send uplink signals on the time-frequency resources occupied by PRACH21 (belonging to PRACH resource pool 21, corresponding to SS21). At this time, PRACH21 will cause strong interference at AP1. AP1 may also schedule downlink signals to terminal 2. At terminal 2 (especially when terminal 2 is also located in area 5), ​​the uplink signal on PRACH21 will also cause strong interference to the downlink signal of terminal 2. Similarly, the PRACH11 signal will also cause strong interference at AP2 or at the end of AP2. And using... Figure 4 Right now Figure 5In the approach on the right, when the terminal is located in area 5, it selects a PRACH resource in PRACH resource pool 5 and sends an uplink access signal on the selected PRACH resource. This avoids frequent switching between multiple APs for terminals in overlapping areas (such as area 5 or area 6). Furthermore, since both AP1 and AP2 detect uplink access signals on the PRACH resources corresponding to the overlapping areas, other terminals will not be scheduled to send or receive other signals on these resources, avoiding the interference issues mentioned above. On the other hand, after receiving the uplink access signal, AP1 and AP2 will promptly know that the terminal is located in the overlapping area. This allows the two APs to jointly serve this terminal, reducing inter-cell interference and improving the performance of users at the cell edge. Moreover, the complexity of PRACH detection at the AP is also reduced. Figure 4 When managing all UEs under the coverage of multiple APs, each AP does not need to detect the PRACH signals sent by all UEs within the unified management area. It only needs to detect the PRACH signals sent by UEs within its coverage area and those at its cell edge. Specifically, it only needs to detect PRACH signals on the PRACH resources corresponding to its synchronization signal group. Each AP corresponds to at least one synchronization signal it sends and A synchronization signal groups to which the at least one synchronization signal belongs. Based on the information determined by the A synchronization signal groups, it transmits the target signal and / or sends control signaling. For example, AP2 only needs to detect the PRACH signals in PRACH resource pools 3, 4, 5, and 6 corresponding to SS groups 3, 4, 5, and 6. It does not need to detect the PRACH signals in PRACH resource groups 1, 2, 7, and 8.

[0159] Figure 4 It's just a way of dividing areas. Figure 6 Another method of regional division is presented. From... Figure 4 and Figure 6 As can be seen, based on P synchronization signals, we can obtain X regions, and X regions correspond to X groups of synchronization signals. Figure 4 Given P=6 and X=8, Figure 6 In the case of P=3 and X=5, where... Figure 6 Each AP sends only one synchronization signal.

[0160] for Figure 4In one scheme, each region corresponds to a separate synchronization signal group. In another contrasting scheme, each region corresponds to a different synchronization signal; that is, each region has only one synchronization signal, and no region corresponds to more than one synchronization signal group. X regions correspond to X synchronization signals, and each synchronization signal is transmitted by one or more APs. A separate synchronization signal is transmitted for each region. When a region corresponds to multiple beams of multiple APs, this synchronization signal is transmitted simultaneously by each AP using its own beam. For example... Figure 5 In the area division shown in the right figure, if this comparison scheme is adopted, eight synchronization signals need to be sent, corresponding to areas 11, 12, 21, 22, 5, 6, 31, and 32 respectively. In area 5, both AP1 and AP2 send synchronization signal SS5. This comparison scheme is compared to... Figure 4 In the previous scheme, each region corresponded to a synchronization signal group. However, in this comparative scheme, the channel characteristics of synchronization signal SS5 changed rapidly in both the time and frequency domains, leading to inaccurate and unstable measurements of the terminal synchronization signal. In contrast, the scheme in this application, for example... Figure 4 In the diagram, the synchronization signals for region 5 include SS21 and SS11, transmitted by AP2 and AP1 respectively. The time and frequency domain changes of SS21 and SS11 are slower than SS5 in the comparison scheme because, compared to SS5, Figure 4 The SS21 and S11 channels in this application contain fewer multipath components and spatial angular components, resulting in smaller delay spread and Doppler spread. Therefore, the solution in this application allows for more stable and accurate measurement of the terminal's synchronization signal, preventing situations where the signal cannot be measured at certain times. On the other hand, in the comparative scheme, the load on the synchronization signal needs to increase with the number of regions, thus increasing the complexity of synchronization signal detection. Therefore, managing regions based on synchronization signal groups, compared to managing regions with a single synchronization signal (i.e., the comparative scheme), results in more accurate and stable synchronization signal detection performance. Furthermore, the base station manages regions more rationally (avoiding the interference and frequent handover issues mentioned above), and can flexibly adjust the region division according to channel conditions. With region-based management, information can be determined based on regions, target signal information can be determined based on regions, and signaling information transmission can be controlled, improving the flexibility and effectiveness of information management.

[0161] When X is greater than P, the load and detection complexity of the synchronization signal can be reduced. Each synchronization signal can correspond to a detection position of a common control channel, which reduces the load and detection complexity of the common control channel while ensuring its detectability and stability.

[0162] When X is less than P, message load can be reduced. For example, message transmission can be done at the region level, such as X synchronization signal groups corresponding to X common control detection locations. Region management based on synchronization signal groups can also differentiate between users in the cell center and users at the cell edge, and allow multiple APs corresponding to a region to communicate simultaneously with terminals that have selected that region, improving AP edge performance and reducing the complexity of PRACH signal detection for each AP. This allows each AP to be activated by the access terminal on demand, rather than all APs serving all UEs under the coverage of multiple APs. It should be noted that... Figure 7 and Figure 6 The regional division shown is just an example and does not exclude other regional division methods.

[0163] The first type of synchronization signal group requires multiple access points (APs) to communicate with users in that area, while the second type only requires one AP. This allows for on-demand AP activation, ensuring similar performance for central and edge users, rather than edge users suffering performance degradation due to interference between APs. Users in different second-type synchronization signal groups can be independently scheduled without mutual interference. Figure 4 Users in groups 1, 2, 3, 4, 7, and 8 can be independently scheduled, with negligible interference between them, and can occupy the same resources. These resources include at least one of the following: time-domain resources, frequency-domain resources, and code-domain resources. For users in different regions corresponding to different synchronization signal groups with the same synchronization signal, interference between them needs to be considered, for example... Figure 4 Users in Group 1 and Group 5 need to consider interference between them. For example, a signal sent to Group 1 can reach a user in Group 5, causing interference. In this case, the signals of users in Group 1 and Group 5 need to be distinguished by at least one of the following: time domain resources, frequency domain resources, code domain resources, and power resources.

[0164] When the number of synchronization signals included in the target synchronization signal group selected by the terminal is greater than one, the first method of PRACH transmission is that the terminal sends the same PRACH signal to multiple APs. The same PRACH signal resides in the same resource, which includes at least one of the following: frequency domain resources, time domain resources, code domain resources, and spatial domain resources. Preferably, the transmission beam and transmission power of the same PRACH synchronization signal are determined based on one or more synchronization signals in the target synchronization signal group. The second method of PRACH transmission is that the terminal sends a PRACH signal to each of the multiple APs. Each of the multiple APs corresponds to one synchronization signal in the target synchronization signal group. For example, multiple synchronization signals correspond to multiple PRACH signals, and the multiple PRACH signals reside in at least one of the following resources: frequency domain resources, time domain resources, code domain resources, and spatial domain resources. For example, the terminal selects multiple PRACH resources from the PRACH resource pool corresponding to the target synchronization signal group and sends them to the APs corresponding to each synchronization signal in this synchronization signal group. Preferably, the PRACH resource pool corresponding to the target synchronization signal group can be divided into multiple subgroups, with different subgroups corresponding to different synchronization signals in this synchronization signal group.

[0165] Figures 7-11 The diagrams illustrating the correspondence between various types of information and various synchronization signal levels are provided. The synchronization signal levels include at least one of the following: a synchronization signal group, a synchronization signal set, or X synchronization signals. Figures 7-11 Schematic diagrams illustrating how to determine information based on synchronization signal groups are also provided. Figure 7 In this process, the first type of information is obtained based on the synchronization signal group index, with each synchronization signal group corresponding to a separate set of the first type of information. The second type of information is then obtained based on the type of the synchronization signal group, with different types of synchronization signal groups corresponding to a separate set of the second type of information. X synchronization signal groups belong to Z synchronization signal sets. Figure 7 In this system, X = 6, Z = 2, and each set of synchronization signals corresponds to a set of third-class information. X sets of synchronization signals correspond to the same fourth-class information. Figure 7 SS groups 1 to 4 each contain one synchronization signal, while SS groups 5 and 6 each contain more than one synchronization signal. Figure 7 SS groups 1-6 and Figure 2 The SS groups 1 through 6 correspond one-to-one. Figure 7 For simplicity, SS groups 7 and 8 are omitted; this does not affect the overall meaning. Figure 7 The meaning to be expressed.

[0166] Figure 8 and Figure 7The difference is that the acquisition of the second type of information is determined not only by the type of synchronization signal, but also by the set of synchronization signals to which the synchronization signal group belongs. For example, the second type of information corresponding to the second type of synchronization signal group under the first set of synchronization signals and the second type of information corresponding to the second type of synchronization signal group under the second set of synchronization signals need to be determined separately, and preferably they are different.

[0167] Figure 9 and Figure 7 The difference is that there is no second type of information. Figure 10 and Figure 7 The difference is that the third type of information corresponding to the first type of synchronization signal group is determined according to the synchronization signal set and the synchronization signal type. The first type of synchronization signal group and the synchronization signal set determine the third type of information respectively. The third type of information corresponding to a synchronization signal set is only applicable to the second type of synchronization signal group that includes the synchronization signals in this synchronization signal set, and is not applicable to the first type of synchronization signal group that includes the synchronization signals in this synchronization signal set. Figure 11 and Figure 10 The difference lies in the fact that the third type of information of the first type of synchronization signal group with different indices needs to be determined separately, preferably, they are different. Figures 7-11 Both types of information (Type III and Type IV) are present, at which point the synchronization signals of multiple synchronization signal sets are managed uniformly. The information determined by the synchronization signal group includes common messages, which then involves how these common messages are sent. Common messages include broadcast messages (such as those included in the PBCH) and at least one of the system messages. The first method determines the common message for each of the X regions separately. The second method ensures that the common messages for the X regions are the same, but at least one of the time-domain, frequency-domain, code-domain, and spatial-domain resources for detecting the common messages differs across the X regions. The third approach includes multiple types of public messages, such as five types. The first type of public message is determined for each of the X regions, at the synchronization signal group level. Preferably, the first type of public message differs for each of the X regions. The second type of public message is determined for different types of regions within the X regions, at the synchronization signal group type level. Preferably, the second type of public message differs for different types of regions. The third type of public message is determined for each set of regions, preferably, the third type of public message differs for Z sets of regions, at the synchronization signal set level. The fourth type of public message corresponds to X synchronization signal groups; for example, X synchronization signal groups may correspond to the same fourth type of public message. The fifth type of public message is determined at the synchronization signal group set level; different synchronization signal groups correspond to different fifth type of public messages. The sixth type of public message is determined for each synchronization signal level; different synchronization signals correspond to different sixth type of public messages. For example... Figures 7-11 The information can include public messages. Figures 7-11In this context, the first to fourth categories of information respectively include first-category public messages and fourth-category public messages. Of course... Figures 7-11 In addition to public messages, each of the first to fourth categories of information can also include proprietary messages.

[0168] In one example, X synchronization signal groups correspond to X PRACH resource pools, and these X PRACH resource pools belong to Z PRACH resource sets. For example, each synchronization signal set corresponds to one PRACH resource set, and the X PRACH resource pools originate from these Z PRACH resource sets. Alternatively, the X PRACH resource pools belong to Z+Z1 PRACH resource sets, where each synchronization signal set corresponds to one PRACH resource set. Preferably, Z1 represents the number of first-type synchronization signal groups (synchronization signal groups containing more than one synchronization signal). X1 second-type synchronization signal groups (synchronization signal groups containing one synchronization signal) under a synchronization signal set divide the corresponding PRACH resource set into X1 parts, and these X1 second-type synchronization signal groups correspond to the X1 PRACH resource pools. PRACH resource pools are then determined for each of the Z1 first-type synchronization signal groups. In PRACH resource allocation, a rule can be followed, such as ensuring that the union of PRACH resource pools corresponding to a set of synchronization signals (also called a PRACH resource pool group) satisfies predetermined characteristics. This can reduce the detection complexity on the AP side. A PRACH resource pool group corresponding to a set of synchronization signals includes one or more PRACH resource pools. Each PRACH resource pool in this group corresponds to a synchronization signal group that includes at least one synchronization signal from that set of synchronization signals. For example... Figure 4 In this context, AP2 corresponds to synchronization signal set 2. At least one synchronization signal in synchronization signal set 2 belongs to synchronization signal groups 3, 4, 5, and 6. Therefore, the union of the PRACH resource pools corresponding to synchronization signal set 2 is the PRACH resources in PRACH resource pools 3, 4, 5, and 6. AP2 needs to detect PRACHs in PRACH resource pools 3, 4, 5, and 6. The union of the PRACH resource pools must satisfy at least one of the following predetermined characteristics: the number of root sequences of the preamble of PRACHs included in the union is less (e.g., less than a first predetermined number); the number of different PRACH occasions in the union is less (e.g., less than a second predetermined number); and one of the PRACH occasions is a combination of time-domain and frequency-domain resources for detecting PRACHs. Multiple PRACH signals in a PRACH occasion are processed using code division. Of course, there are exceptions in some cases... Figures 7-11 Some class information is missing in the example, such as at least one of the third and fourth class information.

[0169] In one implementation, the fourth type of public message includes at least one of the following related information: Z sets of synchronization signals, X groups of synchronization signals, X PRACH resource pools, Z sets of PRACH resources, and Z1 sets of PRACH resources.

[0170] In one implementation, the i-th type of message notifies multiple sets of j-th type information, and the m-th type of message selects one or more sets of j-th type information from the multiple sets of j-th type information to form a synchronization signal group or set of synchronization signals, where i is greater than m, and m is greater than or equal to j. The i-th and m-th type messages include one or more of the first to fourth type of messages. The j-th type of information includes one or more of the first to sixth type of information.

[0171] Figure 4 and Figure 6 It is a method of regional division. Figure 12 Another method of region division is given. For example, in the near field, the base station transmits 5 synchronization signals. The target regions of the 5 synchronization signals are 5 regions on the second range layer. The 5 regions on each range layer correspond to 5 orthogonal near-field beams of the base station. Each region on the first and third range layers corresponds to two synchronization signal layers on the second range layer, respectively. Figure 12 Each region in the first and third range layers corresponds to a synchronization signal group containing two synchronization signals. However, this embodiment does not preclude the possibility that the number of synchronization signals included in the synchronization signal groups corresponding to different regions may differ. Each range layer corresponds to a set of orthogonal bases (also called orthogonal beams) in T-dimensional space. The number of transmitting antennas for the T-dimensional base station is defined. The orthogonal base corresponds to the transmission precoding used by the base station on the T antennas. Each orthogonal base in different range layers can be expressed as a combination of multiple orthogonal bases in other layers. Figure 12 In this context, region 5 will include region 5 on the first range layer and region 5 on the third range layer. For example, the channel on region 5 is a beam-weighted combination of synchronization signal 1 and synchronization signal 2 in the second range layer, so users on region 5 can receive synchronization signal 1 and synchronization signal 2. Figure 13 and Figure 12 The difference is, Figure 13 Will Figure 12 The regions with indices of 6–10 are further distinguished in the second and third distance layers, for example… Figure 12 In the middle, region 6 includes two parts: region 6 on the first distance layer and region 6 on the third distance layer. Figure 13The two parts are divided into region 6 and region 11. Both region 6 and region 11 contain synchronization signal 1 and synchronization signal 2, but their receiving parameters differ. For example, region 6 corresponds to synchronization signal group 6, which includes synchronization signal 1 and synchronization signal 2, as well as the first receiving parameters of synchronization signal 1 and synchronization signal 2. Region 11 corresponds to synchronization signal group 11, which also includes synchronization signal 1 and synchronization signal 2, but with different second receiving parameters. These receiving parameters include at least one of the following: received power, sum of received power, and received phase difference. In this case, among the X synchronization signal groups, two groups contain the same synchronization signal, but their receiving parameters differ.

[0172] Optionally, the synchronization signal groups can be further divided into synchronization signal group sets. For example, the synchronization signal groups on each distance layer constitute a synchronization signal group set. For example, in Figure 13, synchronization signal groups 11 to 15 on the first distance layer constitute the first synchronization signal group set, synchronization signal groups 1 to 5 on the second distance layer constitute the second synchronization signal group set, and synchronization signal groups 6 to 10 on the third distance layer constitute the third synchronization signal group set. The fifth type of information corresponding to each synchronization signal group set needs to be determined separately. Preferredly, the fifth type of information corresponding to different synchronization signal group sets is different. Figure 14 This is a schematic diagram of the near-field range layer, where different circles represent different range layers. Each range layer includes a set of regions, and a synchronization signal sent by the base station is directed to a region on a range layer. Figures 12-13 In this process, the base station only sends P synchronization signals at the distance layer. Figures 12-13 In this case, P=5 allows for the formation of multiple regions across multiple range layers, because each range layer comprises a set of orthogonal beams, and the regions on other range layers can be represented by a linear combination of the synchronization signal range layer beams. For example... Figure 15 As shown, there are 3 sets of synchronization signals, each corresponding to a set of fifth-class information. Figure 15 In this embodiment, different sets of synchronization signal groups correspond to a set of fifth-type information, and the values ​​of the fifth-type information are also different. In another embodiment, the fifth-type information corresponding to the three sets of synchronization signal groups is the same, but at least one of the time-frequency code space resources for detecting the fifth-type information is different.

[0173] In the above embodiments, the first type of information includes at least one of the following: first type parameters of the target signal, first type control signaling information; the second type of information includes at least one of the following: second type parameters of the target signal, second type control signaling information; the third type of information includes at least one of the following: third type parameters of the target signal, third type control signaling information; the fourth type of information includes at least one of the following: fourth type parameters of the target signal, fourth type control signaling information; and the fifth type of information includes at least one of the following: fifth type parameters of the target signal, fifth type control signaling information. The control signaling information includes at least one of the following: Radio Resource Control (RRC) control signaling information, Media Access Control (MAC) Control Element (CE) control signaling information, and DCI control signaling information. Furthermore, the control signaling information may include at least one of the following: higher layer control signaling information, physical layer control signaling information. On the other hand, the control signaling information may also include at least one of the following: broadcast control signaling, common control signaling, common messages, and system messages.

[0174] In the above method, P synchronization signals constitute X synchronization signal groups. Each synchronization signal in the X synchronization signal groups is obtained according to one or more of the following methods: sequence information of the synchronization signal, time-domain resources where the synchronization signal is located, frequency-domain resources where the synchronization signal is located, and signaling notified by the base station. The signaling includes common signaling and / or proprietary signaling. For example, for a first-time user, common signaling is required, and the synchronization signals included in each of the X synchronization signal groups are determined based on the common signaling. For users who have previously accessed the system, proprietary signaling can be used to notify the user of the above information, so that, for example, when the user enters the Idle state or the in-activate state, the information notified by the proprietary signaling can be used for synchronization signal detection. If it is common control signaling, preferably... Figures 7-11 The first type of information may include information from the common control signaling, that is, the first type of information corresponding to each synchronization signal group includes information about the X synchronization signal groups, or the first type of information includes at least the information about the synchronization signal groups. Alternatively, each synchronization signal corresponds to a set of sixth type of information, which includes the synchronization signal group to which the synchronization signal belongs, and the PRACH resource pool information corresponding to these synchronization signal groups. Figure 16 As shown, Figure 16 Based on Figure 15 Based on this, P synchronization signals are added, each corresponding to a sixth type of information. Figure 17 It is also a schematic diagram of a set of values ​​for the sixth type of information corresponding to each synchronization signal. Figure 17Based on Figure 7 Based on this, each of the P synchronization signals corresponds to a sixth type of information. For example, the sixth type of information includes the detection position of the common control channel corresponding to the synchronization signal. When the terminal detects a synchronization signal, it detects the common control channel based on the detection position of the common control channel corresponding to this synchronization signal, and obtains a common message based on the common control channel. The common message may include at least one of the following: common messages of the first type to common messages of the sixth type. Alternatively, the sixth type of information may include the detection position of the broadcast channel, with each synchronization signal corresponding to a detection position of a broadcast channel. The broadcast channel may include at least one of the following: common messages of the first type to common messages of the sixth type, information of X synchronization signal groups, or information of the synchronization signal group to which the synchronization signal corresponding to this broadcast channel belongs. Figures 15-16 In this context, if the sixth type of information includes the detection location of the common control channel, then different synchronization signals correspond to different detection locations of the common control channel. Figures 7-11 In this process, if the first type of information includes the detection location of the common channel, then different synchronization signal groups correspond to different detection locations of the common control channel. Preferably, the following method is used: Figures 15-16 In this way, one or more of the following methods can be used to notify the first type of public message:

[0175] Alt1: Each synchronization signal corresponds to the detection position of a common channel. Different common control channels corresponding to different synchronization signals in a synchronization signal group can point to the transmission of the same common data channel. This common data channel includes at least one of the first to sixth types of information.

[0176] Alt2: Different common control channels corresponding to different synchronization signals in a synchronization signal group can point to different common data channels for transmission. Among the multiple common data channels corresponding to the synchronization signal group, the first type of information is the same.

[0177] Alt3: Each synchronization signal corresponds to a detection position of a common control channel. Based on this common control channel, a sixth type of common message is obtained. This sixth type of common message includes the detection position of the common control channel corresponding to each synchronization signal group. Alternatively, the sixth type of common message includes the detection position of the common control channel corresponding to the synchronization signal group to which this synchronization signal belongs. Alternatively, the common control channel notifies synchronization signals that satisfy a quasi-co-value relationship with the common data channel, thus revealing which synchronization signals correspond to the same common data channel.

[0178] The method of obtaining the first type of public message from the sixth type of public message in Alt1 to Alt3 can be similarly derived to obtain the m type of public message from the j type of public message, except that the sixth type in Alt1 to Alt3 is replaced with the j type, where j is greater than or equal to m. The synchronization signal is replaced with the synchronization signal level corresponding to the j type of public message, and the synchronization signal group is replaced with the synchronization signal level corresponding to the m type of public message. The synchronization signal level includes at least one of the following: synchronization signal group, synchronization signal type, synchronization signal set, synchronization signal group set, and a synchronization signal. The synchronization signal group, synchronization signal type, synchronization signal set, synchronization signal group set, and a synchronization signal correspond to the following public messages in sequence: the first type of public message, the second type of public message, the third type of public message, the fourth or fifth type of public message, and the sixth type of public message.

[0179] In the above description, control signaling can also be referred to as control information or control messages. Control information includes patent control information and public control information. Control information is transmitted in the control channel. Control information can also be transmitted in the data channel, which is scheduled by the control channel. Information transmitted in the broadcast channel PBCH also belongs to public control information.

[0180] In the above embodiment, the terminal obtains Y target synchronization signal groups through the measurement results of the synchronization signals, and obtains the information based on the Y target synchronization signal groups. In another example of this embodiment, the Y target synchronization signal groups are the X synchronization signal groups. The terminal obtains the X synchronization signal groups based on the information indicated in the common control channel. For example, the control information of the common control channel indicates the index of a group of synchronization signals, and this group of synchronization signals constitutes a synchronization signal group. The synchronization signals in the synchronization signal group and the common data channel scheduled by the common control channel satisfy a quasi-co-address relationship. The synchronization signal group is the X synchronization signal groups, where X equals 1, and the Y target synchronization signal groups are also the same synchronization signal group. The above scheme is also suitable for group control channels and group data channels, that is, replacing the common control channel and common data channel with group control channels and group data channels respectively. The common data channel includes common messages, which can also be called system messages. This allows the base station to flexibly send system messages on demand, without requiring each synchronization signal to correspond to a PDSCH location that includes system messages. Figure 4In this system, six synchronization signals correspond to six sets of detection opportunities for CORESET0, with each synchronization signal corresponding to one set of detection opportunities for CORESET0. However, there are four PDSCHs, including system messages. The quasi-co-address reference signals corresponding to these four PDSCHs are the synchronization signals of synchronization signal groups 5, 6, 2, and 8, respectively. The common data channel or the group data channel includes at least one of the following: system messages and PRACH response information.

[0181] In the above embodiments, the terminal side determines information based on Y target synchronization signal groups. In some embodiments, the terminal also needs to determine information based on X synchronization signal groups, which can also be referred to as determining the correspondence between X synchronization signal groups and information. Determining information based on X synchronization signal groups includes determining the information based on at least one of the following: X synchronization signal groups, the set of synchronization signals in each synchronization signal group, the type of the synchronization signal group corresponding to each synchronization signal group, and the set of synchronization signal groups in which each synchronization signal group belongs. Alternatively, the set of synchronization signals and the set of synchronization signal groups can be regarded as different types of synchronization signal groups. For example, the type of synchronization signal group can be determined based on at least one of the following: the number of synchronization signals included in the synchronization signal group, the number of subgroups included in the synchronization signal group, and the number of sequences corresponding to the synchronization signals included in the synchronization signal group.

[0182] In one embodiment, each synchronization signal corresponds to a set of detection opportunities for a common control channel. When a terminal selects a synchronization signal, it detects the common control channel under the common control channel corresponding to that synchronization signal. The control information of the common control channel includes one or more synchronization signal indices that satisfy a quasi-co-address relationship with the common data channel. The common data channel is the data channel scheduled by the common control channel. The above scheme is also suitable for group control channels and group data channels, that is, replacing the common control channel and common data channel with group control channels and group data channels, respectively. The common data channel includes common messages, which can also be called system messages. This allows the base station to flexibly send system messages on demand, without requiring each synchronization signal to correspond to a PDSCH location that includes system messages, for example... Figure 4In this embodiment, six synchronization signals correspond to six detection timing sets for CORESET0, with each synchronization signal corresponding to one detection timing set for CORESET0. However, there are four PDSCHs, including system messages. The quasi-co-address reference signals corresponding to these four PDSCHs are the synchronization signals of synchronization signal groups 5, 6, 2, and 8, respectively. The common data channel or the group data channel includes at least one of the following: system messages and PRACH response information. In this embodiment, there may be no feature constraints on the synchronization signal groups. That is, even without the feature constraints of the synchronization signal groups, the core features of this embodiment can still be established independently. The core features of this embodiment include that each synchronization signal corresponds to one detection timing set for a common control channel. When the terminal selects a synchronization signal, it detects the common control channel under the common control channel corresponding to this synchronization signal. The control information of the common control channel includes one or more synchronization signal indices that satisfy the quasi-co-address relationship with the common data channel.
