Description

Technical Field

[0001] The present disclosure relates to the field of mobile communication technology, and in particular to a communication method, device and system in a non-cellular network. Background Art

[0002] Traditional cellular networks usually reduce the radius of cellular cells and increase the density of base station deployment to improve system capacity. However, due to the lack of effective cooperation between base stations, the interference between cells increases sharply. At the same time, due to the existence of cell edge effects, it is difficult for traditional cellular networks to provide stable network throughput, which makes it difficult to guarantee user experience.

[0003] To solve the above problems of cellular networks, the academic community has proposed cell-free technology. Cell-free is a new concept of wireless access architecture derived from distributed multiple input multiple output (MIMO) technology. Cell-free technology uses distributed MIMO to form a mobile communication system with dynamic resource configuration. Each antenna unit or access point (AP) within the user coverage area can use the same frequency configuration and eliminate interference through joint processing. Theoretical analysis results of cell-free technology show that it has advantages in ensuring network throughput and improving system spectrum efficiency.

[0004] When the cellular-free technology was proposed, a single user was served by all APs, that is, each user needed to access all APs. The above approach not only places extremely high demands on the computing power of the central processing equipment, but also, since the signal quality of APs far away from the user will drop significantly, it is unnecessary for all APs to provide services to the user. Taking the above factors into consideration, the user-centric cellular-free network has become a new networking method. In a user-centric cellular-free network, multiple APs form an AP cluster according to certain rules, and users are only served by APs within the cluster. During user movement, the AP cluster needs to change dynamically to ensure user service quality.

[0005] In the process of non-cellular communication, how to update the AP cluster more efficiently and accurately and ensure the continuity of user services after the AP cluster is updated is an urgent problem to be solved. Summary of the invention

[0038] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0039] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0040] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0041] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0042] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0045] In order to solve the problem of dynamic division of access point clusters in non-cellular network communication, the present disclosure proposes a method, device and system for updating access point clusters in a non-cellular network, which can update the access point clusters more efficiently and accurately, and ensure the continuity of user services after the access point clusters are updated.

[0046] Figure 1 FIG. 1 is a flow chart of a communication method in a non-cellular network according to some embodiments of the present disclosure. Figure 1 As shown, the communication method in a non-cellular network includes steps S11 to S14.

[0047] Step S11: obtaining designated signals sent by multiple access points in the current access point cluster corresponding to the user equipment.

[0048] In some examples, the communication device performs Figure 1 The communication method in the non-cellular network shown in the figure. The communication device may be a device arranged in a central processing unit.

[0049] The current access point cluster refers to a group of access points that currently provide services to the user equipment. The access point refers to a device that provides wireless access services to the user equipment.

[0050] Considering the possibility that users may move and that user service requirements may change, the access point clusters serving users need to be dynamically divided. Figure 1 The method shown is used to timely update the access point cluster serving the user during the user's mobility, thereby better ensuring the service quality. Figure 1 The duration corresponding to the execution cycle (or perception cycle) of the method shown can be a fixed duration or a variable duration that is adaptively updated according to the user's movement.

[0051] In some examples, step S11 may be performed as follows: Figure 2The processing flow shown includes: step S111, within the current perception cycle, the communication device sends indication information to a designated access point in the current access point cluster, and the indication information is used to instruct the designated access point to send a perception signal to the user equipment; step S112, the communication device receives a perception echo signal generated by the perception signal from other access points in the current access point cluster except the designated access point.

[0052] The designated access point may be any access point in the current access point cluster, or an access point in the current access point cluster that meets the set conditions. For example, the designated access point is the access point with the best signal status in the current access point cluster. After the communication device sends the indication information to the designated access point, the designated access point is triggered to send a perception signal to the user equipment. After receiving the perception signal, the user equipment generates a perception echo signal and sends the perception echo signal to other access points in the current access point cluster except the designated access point. Other access points send the perception echo signal to the communication device. The communication device receives the perception echo signal sent by other access points and uses it as the designated signal. The perception signal may multiplex the downlink pilot signal or use a dedicated signal.

[0053] In the embodiments of the present disclosure, collaborative perception is performed based on multiple access points in the current access point cluster, and the perception results are used in the dynamic update of the access point cluster, which helps to improve the accuracy and efficiency of the access point cluster update and alleviate the problem that the dynamic clustering method in the related art causes clustering errors due to prediction errors, thereby reducing the user service quality.

[0054] In addition, in specific implementation, step S11 may also adopt other processing methods. For example, multiple sensing processes may be performed based on the current access point cluster, and sensing echo signals sent by multiple access points may be received in each sensing process. In this way, it is convenient to more accurately determine the location information of the user equipment and the channel state information of the access point and other sensing information based on the sensing echo signals received in the multiple sensing processes.

[0055] Step S12: determining the location information of the user equipment and the channel state information of the plurality of access points according to the designated signal.

[0056] In some examples, in step S12, the location information of the user device is determined as follows: based on a specified signal, the location and motion information of the user device in the current perception cycle is determined; based on the location and motion information of the user device in the current perception cycle, the location information of the user device in the next perception cycle is determined.

[0057] The motion information of the user equipment in the current sensing period includes at least one of the moving speed and moving direction of the user equipment. For example, assuming that the current sensing period is T1 and the next sensing period is T2, the position, moving speed and moving direction of the user equipment in T1 can be calculated based on the sensing echo signals sent by multiple access points in the current access point cluster in the current sensing period, and then the position of the user equipment in T2 can be predicted based on the position, moving speed and moving direction of the user equipment in T1.

[0058] Further, in the above example, the channel state information of multiple access points in the current access point cluster can be determined according to the designated signal sent by the multiple access points in the current access point cluster in the current sensing period. In addition, in a specific implementation, in addition to sensing the location information of the user equipment and the channel state information of the access point according to the same signal, the location information of the user equipment and the channel state information of the access point can also be sensed according to different signals.

[0059] Furthermore, in the above example, the duration of the next sensing cycle is negatively correlated with the moving speed of the user device in the current sensing cycle. For example, when the user's moving speed increases, the duration corresponding to the sensing cycle can be reduced; when the user's moving speed decreases, the duration corresponding to the sensing cycle can be increased.

[0060] Furthermore, in the above example, the duration of the next perception cycle can be determined based on the ratio of the maximum value of the distance between the user device and each access point in the current access point cluster (i.e., the farthest distance between the user device and the access point in the current access point cluster) and the moving speed of the user device in the current perception cycle. For example, the ratio is used as the duration of the next perception cycle. In this way, by adaptively determining the perception cycle, the service clusters can be divided in time during the user movement process, the continuity and quality of the service are guaranteed, and the user can switch between service clusters without feeling.

[0061] Step S13: judging whether to update the current access point cluster according to the location information of the user equipment and the channel state information of the plurality of access points.

[0062] Step S13 can be implemented in a variety of ways, which are described below in combination with two exemplary ways.

[0063] In the first exemplary embodiment, step S13 includes: judging whether the user equipment leaves the signal coverage of the current access point cluster according to the location information of the user equipment in the next sensing cycle; judging whether the channel quality of at least M access points is lower than the quality threshold according to the channel state information of the access point; and determining to update the current access point cluster when the user equipment leaves the signal coverage of the current access point cluster or the channel quality of at least M access points is lower than the threshold; otherwise, not updating the current access point cluster.

[0064] In the second example manner, step S13 includes: judging whether the user equipment leaves the signal coverage of the current access point cluster according to the location information of the user equipment in the next sensing cycle; judging whether the channel quality of at least M access points is lower than the quality threshold according to the channel state information of the access point; judging whether the current access point cluster can meet the current service demand of the user according to the current service demand information of the user equipment; determining to update the current access point cluster when the user equipment leaves the signal coverage of the current access point cluster or the channel quality of at least M access points is lower than the threshold, or the current access point cluster cannot meet the current service demand of the user; otherwise, not updating the current access point cluster.

[0065] In the disclosed embodiment, by first performing collaborative sensing based on multiple access points in the current access point cluster, and then making a judgment based on the collaborative sensing result and the set judgment rules, it is possible to more accurately and in real time know whether the current access point cluster needs to be updated, which not only helps to ensure the service quality for the above-mentioned user equipment, but also reduces unnecessary access point cluster update processes and reduces signaling overhead during the process.

[0066] Step S14: when it is determined to update the current access point cluster, determine an updated access point cluster corresponding to the user equipment.

[0067] There is at least one common access point between the updated access point cluster and the current access point cluster.

[0068] In some embodiments, the communication method in a non-cellular network further includes: when it is determined that the current access point cluster is not to be updated, keeping the current access point cluster corresponding to the user equipment unchanged.

[0069] In the embodiments of the present disclosure, on the one hand, by collaboratively determining the position of the user equipment based on designated signals sent by multiple access points in the current access point cluster, the positioning accuracy of the position of the user equipment can be improved, thereby facilitating more accurate and reliable access point cluster updates; on the other hand, by keeping at least one access point in the access point cluster unchanged, the continuity of the service after the access point cluster update can be guaranteed, thereby improving the user experience.

[0070] Figure 4 FIG. 1 is a flow chart of a communication method in a non-cellular network according to some other embodiments of the present disclosure. Figure 4 As shown, the communication method in a non-cellular network includes step S41 and step S42.

[0071] Step S41: initial access phase.

[0072] In some embodiments, the method for communicating in a non-cellular network is performed by a central processing device.

[0073] The initial access stage includes: step S411, setting an initial cluster according to the location information of the user equipment; step S412, determining the channel state information of each access point according to the pilot signal sent by the user equipment to each access point in the initial cluster; step S413, selecting an access point whose channel quality is greater than a set quality threshold from the initial cluster according to the channel state information of each access point, and using the selected access points whose channel quality is greater than the set quality threshold as a service cluster.

[0074] The following is a detailed description of steps S411 to S413.

[0075] In some examples, in step S411, the central processing device may interact with the user device through control signaling after discovering the user device to determine the location information of the user device based on the control signaling; the central processing device selects an access point whose signal coverage can cover the user device from multiple access points based on the location information of the user device and the signal coverage information of multiple access points that it has acquired, and uses these selected access points as the initial cluster.

[0076] In some examples, in step S412, the central processing device allocates a pilot signal to each access point in the initial cluster, and then instructs the user equipment to send an uplink pilot signal to all access points in the initial cluster; the central processing device determines the channel state information of each access point based on the uplink pilot signal.

[0077] In some examples, in step S413, the central processing device determines whether the channel quality of each access point is less than a set quality threshold based on the channel state information of each access point in the initial cluster. If the channel quality of the access point is less than the set quality threshold, the access point is removed from the initial cluster; otherwise, the access point is retained in the initial cluster. After performing the above operation for each access point in the initial cluster, an access point cluster serving the user equipment is obtained, namely, a service cluster. After the service cluster is generated, all access points in the service cluster provide services for the user equipment.

[0078] Step S42: user service stage.

[0079] After the service cluster is generated, the service cluster provides services for the user equipment. Considering factors such as the possibility of user mobility and changes in user service needs, it is necessary to dynamically divide the service cluster. Furthermore, in order to improve the timeliness of service cluster updates and minimize unnecessary service cluster update processes, it is necessary to periodically determine whether the service cluster needs to be updated during the user service phase, and update the service cluster after determining that the service cluster needs to be updated.

[0080] The following is a detailed description of the periodic service cluster update process during the user service phase. Specifically, the service cluster update process includes steps a to d.

[0081] In step a, within the current sensing cycle, the central processing device selects an access point from the current access point cluster (i.e., the current service cluster), and instructs the selected access point to send a sensing signal to the user equipment. After the user equipment receives the sensing signal, the sensing signal is reflected, thereby generating a sensing echo signal. After receiving the sensing echo signal, other access points in the current access point cluster transmit the sensing echo signal to the central processing device.

[0082] In step b, the central processing device calculates the current position, moving direction and moving speed of the user equipment based on the received multiple sensing echo signals, and predicts the user's position in the next sensing cycle accordingly. At the same time, the central processing device can obtain channel state information of multiple access points from the multiple sensing echo signals.

[0083] In step c, the central processing device determines whether the current access point cluster needs to be updated according to the position of the user equipment in the next sensing period and the channel state information of the multiple access points.

[0084] In step d, the central processing device determines an updated access point cluster corresponding to the user equipment when it is determined that the current access point cluster needs to be updated; and keeps the current access point cluster unchanged when it is determined that the current access point cluster does not need to be updated.

[0085] In order to ensure service continuity after the access point cluster is updated, in step d, the updated access point cluster and the current access point cluster are made to have at least one common access point, that is, at least one access point in the current access point cluster is made to remain unchanged.

[0086] Regarding how to determine which access points remain unchanged in step d, the following will be combined with Figure 5 An example is given. Figure 5 As shown, the process of determining the access points that remain unchanged in the access point cluster update process includes steps S51 to S53.

[0087] Step S51, based on the location information of the user equipment and the location information of each access point in the current access point cluster, the signal strength of the signal sent by each access point to the user equipment is calculated using a channel model.

[0088] For example, in step S51, the central processing device calculates the signal strength when the signals sent by all access points in the current access point cluster reach the user device based on the location information of the user device in the next sensing cycle and the location information of each access point in the current access point cluster using the Rayleigh channel model. In addition, in the specific implementation, in addition to the above-mentioned Rayleigh channel model, other channel models may also be used.

[0089] Step S52: taking the access points in the current access point cluster whose signal strength is greater than the strength threshold as a candidate access point set.

[0090] In this step, all access points in the current access point cluster whose signal strength is greater than a strength threshold form a candidate access point set.

[0091] Step S53: When the candidate access point set includes multiple candidate access points, select an access point that remains unchanged from the candidate access point set according to the communication service type corresponding to the user equipment.

[0092] In some examples, step S53 specifically includes: when the communication service type is the first type, all candidate access points in the candidate access point set are used as unchanged access points, wherein the first type is a service that requires throughput, such as a service that requires high throughput (such as a high-definition video service); when the communication service type is the second type, the first N candidate access points with the largest signal strength in the candidate access point set are used as unchanged access points, N is an integer greater than 1 and less than the total number of candidate access points in the candidate access point set (for example, N is 2), and the second type is a service that requires reliability, such as a service that requires high reliability; when the communication service type is a service type other than the first type and the second type, the candidate access point with the largest signal strength in the candidate access point set is used as the unchanged access point.

[0093] In some embodiments, the process of determining the access point to be maintained unchanged in the access point cluster update process further includes: when the candidate access point set includes one candidate access point, using the candidate access point as the access point to be maintained unchanged. In other words, using the candidate access point as an access point in the updated access point cluster.

[0094] In some embodiments, the process of determining the access point that remains unchanged in the access point cluster update process further includes: when the candidate access point set is empty, the access point with the largest signal strength in the current access point cluster is used as the access point that remains unchanged. In other words, the candidate access point is used as an access point in the updated access point cluster. Further, when the candidate access point set is empty, the central processing device may also instruct to increase the signal transmission power of the access point that remains unchanged, so that the signal strength of the signal emitted by the access point when it reaches the user equipment is greater than the strength threshold. In this way, it is helpful to improve the quality of service provided to the user after the access point cluster is updated.

[0095] In the embodiments of the present disclosure, by considering not only the channel status of each access point in the current access point cluster but also the service type of the user equipment when determining the access point that remains unchanged in the current access point cluster, a more suitable access point that remains unchanged can be selected from the current access point cluster, and the quality of service provided to the user after the access point cluster is updated can be better guaranteed.

[0096] In the disclosed embodiment, the access point cluster can be updated more efficiently and accurately through the above process, thereby ensuring the continuity of user services after the access point cluster is updated.

[0097] The following combination Figure 6 and Figure 7 The possible execution results of the communication method of the above embodiment of the present disclosure are described.
