User grouping method based on network node transmission and related equipment
[0001] This disclosure is based on the Chinese patent application with application number 202310953314.2, application date July 31, 2023, and invention name “User grouping method, device, equipment and medium based on network node transmission”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field
[0002] The present disclosure relates to the technical field of wireless communications, and in particular to a user grouping method based on network node transmission, a user grouping device based on network nodes, an electronic device, a computer-readable storage medium, and a computer program product. Background Art
[0003] Intelligent Reflecting Surfaces (IRS) or Reconfigurable Intelligent Surfaces (RIS) are composed of a large number of low-cost electromagnetic units. By adjusting the parameters (such as phase) of each unit, the reflection or transmission direction of the signal incident on the smart surface can be controlled, allowing the signal to be reflected or transmitted in the desired direction. Due to its low cost, low power consumption, and easy deployment, RIS is expected to become a candidate technology for wireless communications in the sixth generation mobile network (6G) standard.
[0004] In related technologies, dynamically adjustable RIS allows the base station to control signal reflection or transmission in a desired direction. However, RIS is transparent to user equipment (UE), meaning the UE cannot perceive changes in RIS. Under these conditions, the network cannot identify users who require RIS-assisted transmission, nor can it identify users who can be directly served by the network without RIS-assisted forwarding. This makes subsequent transmission scheduling on the network difficult, resulting in low scheduling efficiency.

However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0029] In addition, the accompanying drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the figures denote identical or similar parts, and thus repetitive descriptions thereof will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.
[0030] FIG1 is a schematic diagram showing an exemplary system architecture of a user grouping method based on network node transmission or a user grouping device based on network node transmission that can be applied to an embodiment of the present disclosure.
[0031] As shown in FIG. 1 , the system architecture 100 may include user terminals 101 , 102 , and 103 , a network 104 , a network node 105 , and a network-side device 106 .
[0032] The network 104 is used as a medium to provide communication links between the user terminals 101, 102, 103 and the network node 105, and between the network node 105 and the network-side device 106, and may be a wireless network.
[0033] In some embodiments, the wireless network described above uses standard communication technologies and / or protocols. The network is typically the Internet, but may be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wireless network, a private network, or any combination of a virtual private network. In some embodiments, technologies and / or formats including Hypertext Markup Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may be used to replace or supplement the above-mentioned data communication technologies.
[0034] The user terminals 101 , 102 , and 103 may be various electronic devices, including but not limited to smartphones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, and the like.
[0035] In some embodiments, the user terminals of the applications installed in different user terminals 101, 102, and 103 are the same, or are user terminals of the same type of application based on different operating systems. Based on different terminal platforms, the specific form of the user terminal of the application can also be different. For example, the application client can be a mobile phone user terminal, a PC user terminal, etc.
[0036] The network node 105 can be an intelligent reflecting surface (IRS), a reconfigurable intelligent surface (RIS), an intelligent repeater or an intelligent relay device. It can intelligently adjust the wireless propagation environment between the user terminals 101, 102, 103 and the network side device 106 by integrating a large number of low-cost reflection / transmission elements on the plane, thereby significantly improving the performance of the wireless communication network.
[0037] The network side device 106 can be an evolved Node B (eNB), a 5G base station (gNB), or a later version of a base station, a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a Home evolved NodeB, or a Home Node B, HNB), a baseband unit (BBU), a wireless fidelity (WIFI) access point (AP), a transmission point (TRP or TP), or other terms in the field. As long as the same technical effect is achieved, the network device is not limited to specific technical terms.
[0038] The network side device 106 can be a 4G base station, a 5G base station, a higher version of a base station, or a base station in other communication systems, or called a node B, an evolved node B, or a transmission reception point (TRP), or an access point (AP), or a WiFi device, or other terms in the field. As long as the same technical effect is achieved, the network side device is not limited to specific technical terms.
[0039] Network node 105 features low cost, low power consumption, and easy deployment. RIS can be controlled by network-side device 106, for example, a base station, but is transparent to the user equipment (UE), meaning the UE may be unaware of the existence of RIS. When network node 105 is present, two transmission modes exist: the network-side device directly sends data to the user terminal, and the network-side device forwards the data to the user terminal via the network node.
[0040] However, how to distinguish which users need RIS-assisted forwarding and which users do not need RIS-assisted forwarding has become a technical problem that needs to be solved urgently.
[0041] In order to solve the above problem, in one embodiment, the network side device 106 can use the beams in the first beam group and the second beam group to broadcast information. The beams in the first beam group do not point to the network node 105, and the beams in the second beam group point to the network node 105. The users who select the beams in the first beam group during the random access process are divided into the first user group, and the users who select the beams in the second beam group during the random access process are divided into the second user group; users belonging to the first user group are screened from the second user group, users belonging to the first user group are extracted from the second user group, and users belonging to the first user group are divided into the first user group to realize user grouping, so as to perform data transmission according to the first user group and the second user group, thereby improving subsequent scheduling efficiency.
[0042] Those skilled in the art will appreciate that the number of user terminals, networks, network nodes, and network-side devices in FIG1 is merely illustrative, and any number of user terminals, networks, network nodes, and network-side devices may be provided as needed, and the present disclosure does not limit this.
[0043] Based on this, the present disclosure provides a user grouping method based on network node transmission. This method uses beams from a first beam group and a second beam group to transmit broadcast information. The beams in the first beam group do not point toward network nodes, while the beams in the second beam group do. Users who select beams from the first beam group during random access are grouped into a first user group, while users who select beams from the second beam group during random access are grouped into a second user group. Users belonging to the first user group are screened from the second user group, removed from the second user group, and assigned to the first user group. This method can determine which users require RIS-assisted forwarding and which do not, thereby facilitating subsequent transmission scheduling by network-side devices and improving transmission efficiency.
[0044] This exemplary implementation is described in detail below with reference to the accompanying drawings and examples.
[0045] First, an embodiment of the present disclosure provides a user grouping method based on network node transmission, which can be executed by any electronic device with computing and processing capabilities.
[0046] FIG2 shows a flow chart of a method for grouping users based on network node transmission in an embodiment of the present disclosure. As shown in FIG2 , the method for grouping users based on network node transmission provided in an embodiment of the present disclosure is applied to a network-side device and includes the following steps:
[0047] S202: Use beams in the first beam group and the second beam group to transmit broadcast information, wherein the beams in the first beam group do not point to the network node, and the beams in the second beam group point to the network node.
[0048] It should be noted that the first beam group and the second beam group include at least one beam, and the beams have different beam indexes.
[0049] In one embodiment, the first beam group includes one or more beams, and all beams in the first beam group do not point to the network node, that is, the one or more beams do not point to the network node.
[0050] Exemplarily, one or more beams in the first beam group may be synchronization signal block (SSB) beams of a 5G system.
[0051] In one embodiment, the second beam group includes one or more beams, and all beams in the second beam group are directed to the network node, that is, the one or more beams in the second beam group are directed to the network node.
[0052] Exemplarily, one or more beams in the second beam group may be SSB beams of a 5G system.
[0053] It should be noted that during wireless communication, the beams in the first beam group are the beams used by the network-side device to transmit data directly to the user terminal, that is, the beams used in the scenario where no network node assistance is required; the beams in the second beam group are the beams used by the network-side device to forward data to the user terminal through the network node, that is, the beams used in the scenario where network node assistance is required.
[0054] In one embodiment, the network-side device configures the beams in the first beam group and the beams in the second beam group, and the beams in the first beam group and the beams in the second beam group have different beam indexes.
[0055] When the network side device uses the beams in the first beam group and the second beam group to transmit broadcast information, the broadcast information carries the beam index for the cell search process, so that the user terminal performs cell search according to the beam speed index, completes the random access process, and accesses the current cell.
[0056] It should be noted that the beam indices of the multiple beams in the first beam group are different, the beam indices of the multiple beams in the second beam group are different, and the beam indices corresponding to the beams in the first beam group and the beam indices corresponding to the beams in the second beam group are different. The beam index can be represented by one or more of numbers, letters, symbols, etc.
[0057] For example, the first beam group includes two beams, and the beam indices of the beams in the first beam group are beam #1 and beam #2 respectively; the second beam group includes three beams, and the beam indices corresponding to the three beams in the second beam group are beam #3, beam #4 and beam #5 respectively.
[0058] In one embodiment, the network node is a node that forwards data transmitted by the network side device. The network node can be an intelligent reflective surface, a reconfigurable intelligent surface, an intelligent repeater or an intelligent relay device. The network node can forward signals through beamforming.
[0059] S204: Group users who select beams in the first beam group during random access into a first user group, and group users who select beams in the second beam group during random access into a second user group.
[0060] In one embodiment, the first user group and the second user group respectively have corresponding user group identifiers, which are used to distinguish different user groups. Different user groups adopt different transmission strategies. For example, for users in the first user group, there is no need for network node-assisted transmission, and data can be transmitted directly by the network side device. For users in the second user group, network node-assisted transmission is required, and the data transmitted by the network side device is forwarded to the user terminal through the network node.
[0061] The user group identifier may be one or more of words, numbers, letters, symbols, etc. For example, group 1# is used to represent the first user group, and group 2# is used to represent the second user group.
[0062] In one embodiment, when the user terminal receives a message broadcast by the network side device, the user terminal randomly selects a beam in the first user group or the second user group and accesses the current cell.
[0063] S206: Filter users belonging to the first user group from the second user group, remove the users from the second user group, and assign the users to the first user group.
[0064] In one embodiment, the network side device further and more carefully screens whether there are users belonging to the first user group in the second user group. At this time, the network side device can configure a group of reference signals for measurement, and use the beam in the first beam group or the second beam group to transmit the reference signal, so that the user terminal measures the reference signal, and reports the measurement report obtained by the measurement to the network side device. The network side device determines the relationship between the relevant parameters in the measurement report and the preset conditions, and confirms whether the above-mentioned user terminal belongs to the user of the first user group.
[0065] When a user belonging to the first user group is screened, the user is removed from the second user group and is classified into the first user group.
[0066] Exemplarily, the user group identifier corresponding to the filtered users belonging to the first user group may be modified from the user group identifier of the second user group to the user group identifier of the first user group.
[0067] It should be noted that reference signals can be transmitted to user terminals in the second user group one by one, and it can be determined individually whether the above-mentioned user terminals belong to users of the first user group until all users in the second user group are traversed; reference signals can also be transmitted to user terminals in the second user group at the same time, and each user terminal can be determined whether it belongs to a user of the first user group; in addition, it can be determined whether there are users in the second user group belonging to the first user group in a time-sharing, grouping or other manner according to the situation.
[0068] In one embodiment, the method further includes: the second user group needs to be assisted in transmission by the network node, and the first user group does not need to be assisted in transmission by the network node.
[0069] In the disclosed embodiments, beams from a first beam group and a second beam group are used for broadcast information transmission. The beams from the first beam group are not directed toward network nodes, while the beams from the second beam group are directed toward network nodes. Users who select beams from the first beam group during random access are assigned to a first user group, while users who select beams from the second beam group during random access are assigned to a second user group. Users belonging to the first user group are screened from the second user group, removed from the second user group, and assigned to the first user group. The disclosed embodiments can determine which users require RIS-assisted forwarding and which do not, thereby facilitating subsequent transmission scheduling by network-side devices and improving transmission efficiency.
[0070] FIG3 is a flow chart of a method for determining whether a user terminal belongs to the first user group in an embodiment of the present disclosure. As shown in FIG3 , in one embodiment, the above-mentioned step S206 of filtering users belonging to the first user group from the second user group includes:
[0071] S302. Configure a set of reference signals for measurement, and transmit the reference signals using beams belonging to the same beam group, so that the user terminal measures the reference signals, obtains measurement results, and reports the measurement results, where the measurement results include the received power (RSRP) of the reference signals.
[0072] S304: If the RSRP of the reference signal meets a preset condition, determine that the user terminal is a user belonging to the first user group.
[0073] It should be noted that the above-mentioned reference signal is a signal sent for the purpose of measurement or monitoring in wireless communication, and the parameter signals used for measurement configured by the network-side device may include at least two.
[0074] In one possible implementation, the reference signal may include at least one of the following: a synchronization signal in SSB, a channel state information reference signal, a tracking reference signal, and a sounding reference signal.
[0075] In one embodiment, the reference signal may be transmitted to the user terminal using a beam in the first beam group; or may be forwarded to the user terminal via a network node using a beam in the second beam group.
[0076] The above preset conditions may be pre-configured in the network side device and may be determined according to actual conditions. According to the relationship between the RSRP of the reference signal reported by the user terminal and the preset conditions, it is determined whether the user terminal belongs to the first user group.
[0077] FIG4 is a flowchart illustrating a specific example of a method for determining whether a user terminal belongs to a first user group according to an embodiment of the present disclosure. As shown in FIG4 , in one embodiment, the user grouping method based on network node transmission provided by the embodiment of the present disclosure includes:
[0078] S3022. Use different beams in the first beam group to transmit a reference signal;
[0079] S3042: If the RSRP of at least one reference signal is greater than a preset power threshold, determine that the RSRP of the reference signal meets a preset condition.
[0080] The above-mentioned preset power threshold may be pre-configured in the network-side device as a way of implementing the preset condition. The value of the preset power threshold may be determined according to actual conditions.
[0081] In one possible implementation, when the RSRP of at least one reference signal is greater than a preset power threshold, it is determined that the RSRP of the reference signal meets the preset condition, and then the above-mentioned user terminal is obtained as a user belonging to the first user group. The user terminal needs to be removed from the second user group and divided into the first user group.
[0082] In another possible implementation, when the RSRP of the reference signal reported by the user terminal is less than or equal to the preset power threshold, it is determined that the RSRP of the reference signal does not meet the preset conditions, and then the above-mentioned user terminal is obtained as a user belonging to the second user group and not a user belonging to the first user group, and there is no need to perform elimination or grouping operations.
[0083] FIG5 is a flowchart illustrating another specific example of a method for determining whether a user terminal belongs to a first user group according to an embodiment of the present disclosure. As shown in FIG5 , in one embodiment, the method for grouping users based on network node transmission provided by the embodiment of the present disclosure includes:
[0084] S3024: The reference signal is transmitted using a beam in the second beam group, and the network-side device controls the network node to forward different reference signals using different beam forwarding patterns.
[0085] S3044: If the number of reference signals whose RSRP is greater than the preset power threshold is greater than or equal to the preset number threshold, determine that the RSRP of the reference signal meets the preset condition.
[0086] In one embodiment, the network side device configures a group of reference signals for measurement, uses the beams in the second beam group to transmit the above reference signals, the beam direction in the second beam group points to the network node, and the above reference signals are forwarded to the user terminal via the network node.
[0087] The network-side device can control the network nodes to forward different reference signals using different forwarding patterns. The forwarding pattern can be an electromagnetic wave pattern with a specific reflection / projection pattern formed by adjusting the electromagnetic elements, or a reflection / projection beam pattern pointing in certain specific directions.
[0088] It should be noted that the above-mentioned preset quantity threshold is pre-configured in the network side device. As another implementation method of the preset condition, the preset quantity threshold can also be configured to be related to the number of reference signals. For example, the preset quantity threshold can be configured to be a value greater than or equal to 2 and less than the number of reference signals.
[0089] In one possible implementation, when the number of reference signals whose RSRP is greater than a preset power threshold is greater than or equal to a preset number threshold, it is determined that the RSRP of the reference signal meets the preset condition, and then the above-mentioned user terminal is obtained as a user belonging to the first user group. The user terminal needs to be removed from the second user group and divided into the first user group.
[0090] In another possible implementation, when the number of reference signals whose RSRP is greater than a preset power threshold is less than a preset number threshold, it is determined that the RSRP of the reference signal does not meet the preset conditions, and then the above-mentioned user terminal is obtained as a user belonging to the second user group and not a user belonging to the first user group, and there is no need to perform elimination or grouping operations.
[0091] In an embodiment of the present disclosure, a reference signal is transmitted by using a beam in the first beam group or the second beam group, so that the user terminal in the second user group measures the reference signal and reports the measurement result to the network side device. The network side device determines whether the above-mentioned user terminal belongs to the user in the first user group based on the measurement result, thereby realizing accurate grouping of users, facilitating subsequent scheduling of network side devices, and improving scheduling efficiency and transmission efficiency.
[0092] In one embodiment of the present disclosure, as shown in FIG6 , it is a schematic diagram of a specific example of a user grouping system based on network node transmission in an embodiment of the present disclosure.
[0093] In one embodiment, a beam in the second beam group 202 is used to transmit a reference signal.
[0094] As shown in FIG6 , the system structure may include user terminals 101 and 102 , a network node 105 and a network-side device 106 .
[0095] The network side device 106 uses the beams in the first beam group 201 and the second beam group 202 to transmit broadcast information, wherein the beams in the first beam group 201 do not point to the network node 105, and the first beam group 201 includes beam 1# and beam 2#; the beams in the second beam group 202 point to the network node 105, and the second beam group 202 includes beam 3#, beam 4# and beam 5#.
[0096] Both user terminal 102 and user terminal 101 randomly access the current cell through the beams in the second beam group 202 .
[0097] For example, user terminal 101 and user terminal 102 select beam #3 in the cell search, but in fact user terminal 102 does not need the assistance of network node 105. The cell where user terminal 102 is located belongs to the direct coverage range of network side device 106, for example, the base station directly covers the above cell.
[0098] Network-side device 106 configures reference signals #3, #4, and #5 and transmits the reference signals using beam #3 in second beam group 202. Network-side device 106 controls network node 105 to forward reference signals #3, #4, and #5 using beam forwarding pattern 203, beam forwarding pattern 204, and beam forwarding pattern 205, respectively.
[0099] User terminal 101 belongs to the beam direction of beam forwarding pattern 203, so the RSRP of reference signal #3 measured by user terminal 101 is relatively good. In contrast, the RSRP of reference signals #4 and #5 (corresponding to beam forwarding pattern 204 and beam forwarding pattern 205, respectively) measured by user terminal 101 is relatively poor. The network device receives the measurement results reported by user terminal 101. Only the RSRP of reference signal #3 is greater than the preset power threshold, while the RSRP of reference signals #4 and #5 is less than the preset power threshold. Therefore, the network device determines that user terminal 101 belongs to the second user group and does not make any adjustments.
[0100] User terminal 102 does not belong to any beam direction of the beam forwarding pattern. For reference signals #3-#5, since they use the same beam pointing direction towards network node 105, from the perspective of user terminal 102, apart from the impact of the time-varying channel, the large-scale fading of these signals is similar. Therefore, the RSRP of reference signals #3-#5 measured by user terminal 102 does not vary significantly. The network device receives the measurement results reported by user terminal 102 and finds that the RSRP of reference signals #3, #4, and #5 are all greater than the preset power threshold. Therefore, network device 106 determines that user terminal 102 belongs to the first user group, removes it from the second user group, and adds it to the first user group.
[0101] In another embodiment, the reference signal is transmitted using the beams in the first beam group 201 .
[0102] As shown in FIG6 , the first beam group 201 includes beam #1 and beam #2, neither of which points to the network node 105 ; the second beam group 202 includes beams #3 to #5, all of which point to the network node 105 , such as the RIS.
[0103] Both user terminal 102 and user terminal 101 randomly access the current cell through the beams in the second beam group 202 .
[0104] For example, user terminal 101 and user terminal 102 select beam #3 in the cell search, but in fact user terminal 102 does not need the assistance of network node 105. The cell where user terminal 102 is located belongs to the direct coverage range of network side device 106, for example, the base station directly covers the above cell.
[0105] The network-side device 106 configures reference signals #1 and #2, and uses beam #1 and beam #2 to transmit the reference signals.
[0106] User terminal 102 is within the forwarding beam coverage of network node 105. Therefore, the measured RSRPs of reference signals #1 and #2 are very poor, and may even be unable to receive the corresponding reference signals. In other words, no reference signal has an RSRP greater than a preset power threshold. Therefore, network device 106 determines that user terminal 102 belongs to the second user group and makes no adjustments.
[0107] User terminal 101 is roughly within the coverage of beam #2 and measures a good RSRP for reference signal #2. Network device 106 receives a measurement report from user terminal 101 and finds that the RSRP for reference signal #2 is greater than a preset power threshold. Therefore, network device 106 determines that user terminal 101 belongs to the first user group, removes it from the second user group, and adds it to the first user group.
[0108] It should be noted that, in the actual data transmission process, only the users in the second user group may be traversed to filter out the users belonging to the first user group.
[0109] Based on the same inventive concept, the present disclosure also provides a user grouping device based on network node transmission, as described in the following embodiments.

[0115] In one embodiment, the user group adjustment module 703 is configured to transmit a reference signal using different beams in the first beam group; if the RSRP of at least one reference signal is greater than a preset power threshold, it is determined that the RSRP of the reference signal meets a preset condition.
[0116] In one embodiment, the user group adjustment module 703 is configured to transmit a reference signal using a beam in the second beam group, and the network-side device controls the network node to forward different reference signals using different beam forwarding patterns; if the number of reference signals whose RSRP is greater than a preset power threshold is greater than or equal to a preset number threshold, it is determined that the RSRP of the reference signal meets a preset condition.
[0117] It should be noted that the first beam group and the second beam group include at least one beam, and the beams have different beam indexes.
