Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a coverage enhancement method and a communication device. Background Art

[0002] With the rapid development of wireless communication technology, the 4th Generation Long Term Evolution (4G LTE) and the 5th Generation New Radio (5G NR) have become the core technology systems of modern mobile communication networks. Whether in 4G LTE or 5G NR, user equipment (UE) needs to complete initial access before using network services.

[0003] In the prior art, before a UE accesses the network, the network cannot know whether there are UEs that need to access the network in the cell, nor can it know the number and distribution of UEs. Therefore, regardless of whether there are UEs that need to access the network in the cell, and regardless of the distribution of these UEs, the base station needs to periodically broadcast access information to the cell to provide reliable public channel coverage, help UEs discover cells, complete synchronization, and initiate initial access; otherwise, the UE may not be able to access the network.

[0004] However, when there are no UEs that need to access the network in the cell, the base station will continue to broadcast access information, which not only takes up a lot of base station processing power, time-frequency resources and beam resources, but also may lead to a waste of network energy, reducing network coverage and resource utilization efficiency. Summary of the invention

For example, A and / or B can mean: A exists, A and B can exist at the same time, and B exists. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0058] In the description of this application, unless otherwise specified, "multiple" and "at least two" mean more than two (including two). Similarly, "multiple groups" and "at least two groups" mean more than two groups (including two).

[0059] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, "connected" or "connection" can refer to not only physical connection, but also electrical connection or signal connection. For example, it can be directly connected, that is, physically connected, or indirectly connected through at least one intermediate element, as long as the circuit is connected, or it can be the internal connection of two elements; signal connection can refer to signal connection through a circuit or through a media medium, such as radio waves. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings. It should be noted that different technical features in the present application can be combined with each other without conflict.

[0061] With the rapid development of wireless communication technology, 4G LTE and 5G NR have become the core technology systems of modern mobile communication networks. Whether in 4G LTE or 5G NR, UE needs to complete initial access before using network services.

[0062] In the related art, before the UE accesses the network, the network cannot know whether there are UEs that need to access the network in the cell, nor can it know the number and distribution of UEs. Therefore, regardless of whether there are UEs that need to initiate initial access in the cell, and regardless of the distribution of UEs, the base station needs to broadcast access information to the cell periodically without distinction, so as to provide good public channel coverage for all areas in the cell, so as to facilitate UE to discover the cell, achieve downlink synchronization, and then initiate initial access; otherwise, the UE may be unable to access the network.

[0063] However, when there is no UE that needs to access the network in the cell, the base station will continue to broadcast access information, resulting in a waste of network energy, which is not conducive to network energy saving; at the same time, it also causes a waste of base station processing power and video resources, which is not conducive to reducing base station costs and network performance optimization, thereby reducing network coverage capabilities and resource utilization efficiency.

[0064] Especially in the non-terrestrial network (NTN) scenario based on 5G NR, since the satellite base station needs to cover a very wide ground area, in order to ensure that all UEs in the satellite base station coverage area can access the network, the satellite base station must broadcast access information to its coverage area. When the satellite base station broadcasts access information to its coverage area, a large amount of energy is consumed, and the energy consumption of excessive broadcasting may exceed the upper limit of the satellite's payload design, thereby increasing the manufacturing and incurrence costs of the satellite. In addition, when the satellite base station broadcasts access information to its coverage area, it also needs to occupy a large amount of downlink beam resources, downlink time and frequency resources, which may exceed the design upper limit of the system, thereby limiting the effective coverage of the network and the ability of UE to access. For example, in some cases, excessive allocation of beam resources may make the system unable to provide effective services to UEs, resulting in access delays, reduced communication quality and other problems.

[0065] Based on the problems existing in the related art, the present application provides a coverage enhancement method, in which the network side device configures the wave position in the coverage area of ​​the base station as an activated wave position and / or a silent wave position through preset rules. In the activated wave position, the network side device broadcasts access information to determine whether the UE in the activated wave position can access the network; in the silent wave position, the network side device only detects whether there is a UE in the silent wave position through the first uplink beam to avoid unnecessary downlink broadcasts. If the network side device detects the UE in the silent wave position through the first uplink beam, the network side device converts the wave position from the silent wave position to the activated wave position and broadcasts the access information. Compared with the prior art, the present application introduces an on-demand dynamic management mechanism for activated wave positions and silent wave positions, thereby avoiding broadcasting downlink information in silent wave positions where access services are not required, thereby reducing unnecessary resource consumption, saving network energy, and significantly improving the coverage capability and resource utilization efficiency of the network. Especially in satellite or non-terrestrial network NTN environments with scarce resources and wide coverage, the present application can effectively reduce energy consumption, improve network coverage capability and terminal access efficiency through on-demand activation, and ultimately enhance overall network performance and reduce operating costs.

[0066] Next, some specific embodiments and drawings are used to describe in detail how the present application solves the problems of waste of network energy caused by blind broadcasting of access information by the above-mentioned base stations, as well as low network coverage capability and resource utilization efficiency.

[0067] The technical solution provided in the embodiment of the present application is mainly applicable to wireless communication systems. The wireless communication system can comply with the wireless communication standard of the third generation partnership project (3GPP). For example, the solution provided in the embodiment of the present application can be applied to 4G systems, such as LTE communication systems, and can also be applied to 5G communication systems, such as 5G NR communication systems, or to various future communication systems, such as the sixth generation (6th generation, 6G) communication system. The method provided in the embodiment of the present application can also be applied to satellite communication systems; wherein the satellite communication system can be integrated with the above-mentioned communication system.

[0068] A possible network architecture applicable to the present application may include two parts: terminal equipment and network side equipment.

[0069] Among them, the terminal device may include a device that provides voice and / or data connectivity to the user, for example, it may include a handheld device with a wireless connection function, or a processing device connected to a wireless modem. The terminal device can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal device may include a user equipment UE, a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a vehicle to everything (V2X) terminal device, a machine-to-machine / machine-type communication (M2M / MTC) terminal device, an Internet of Things (IoT) terminal device, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point (AP), a remote terminal device, an access terminal device, a user terminal, a user agent, or a user device, etc. For example, it may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices.

[0071] Figure 1 A flowchart of a coverage enhancement method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, a coverage enhancement method provided in an embodiment of the present application specifically includes S101 to S103, and S101 to S103 are described in detail below.

[0072] Among them, the executor of the coverage enhancement method provided in this embodiment is a network side device.

[0073] S101. A network-side device configures a target wave position as an activated wave position or a silent wave position according to a preset rule.

[0074] The target wave position is any wave position within the coverage area of ​​the base station.

[0075] It should be noted that the earth's surface is divided into multiple service areas, each of which corresponds to a wave position, and the wave position is fixedly associated with the earth's surface. When a wave position requires satellite communication services, the satellite phased array antenna adjusts the beam direction to ensure continuous coverage of the wave position until the wave position no longer needs service. The target wave position refers to any wave position within the base station coverage area.

[0076] In wireless communications, base stations form different beams through phased array antennas, and each beam covers a beam position at each moment. A base station may cover multiple beam positions, and the size and signal strength of each beam position are affected by the configuration of the base station antenna, the geographical environment, and other factors.

[0077] The activated beam position refers to the beam position where the base station periodically broadcasts access information, and the silent beam position refers to the beam position where the base station does not broadcast access information.

[0078] It should be noted that the access information broadcast by the base station to the cell is used to provide reliable public channel coverage, help UE discover the cell, complete synchronization and initiate initial access. The content of the access information broadcast by the base station to the cell is prior art and will not be described in detail in this embodiment.

[0079] For example, in 5G NR, the access information broadcast by the base station to the cell includes common channels such as synchronization signal (SS), physical broadcast channel (PBCH) and system information block (SIB). Synchronization signals include primary synchronization signal (PSS) and secondary synchronization signal (SSS).

[0080] It should be noted that, in the coverage area of ​​the base station, there may be only activated beam positions without silent beam positions; there may be only silent beam positions without activated beam positions; there may also be both activated beam positions and silent beam positions.

[0081] The area corresponding to the activated wavelet is the activated coverage area of ​​the base station. The number of activated wavelets in the activated coverage area may be one or more, which is not specifically limited in this embodiment.

[0082] The area corresponding to the silent beam position is the silent coverage area of ​​the base station. The number of silent beam positions in the silent coverage area may be one or more, which is not specifically limited in this embodiment.

[0083] S102: When the antenna beam corresponding to the base station covers the silent beam position, the network side device allocates a first uplink beam to the silent beam position, and detects a beacon signal sent by the first UE in the silent beam position based on the first uplink beam.

[0084] The first UE refers to a UE that needs to access the network in the silent beam. The first uplink beam is used by the network side device to detect the beacon signal sent by the first UE in the silent beam.

[0085] It should be noted that the network side device allocates the first uplink beam to the silent wave position so that when the first UE in the silent wave position sends a beacon signal, the network side device can detect the presence of the first UE in the silent wave position.

[0086] In this embodiment, when there are multiple silent wave positions in the silent coverage area of ​​the base station, the network side device can allocate a first uplink beam to each silent wave position, and simultaneously detect whether there is a first UE sending a beacon signal in the multiple silent wave positions; or a first uplink beam can be allocated to multiple silent wave positions, and a first uplink beam can use time division multiplexing, rotation or scanning to detect whether there is a first UE sending a beacon signal in multiple silent wave positions. This embodiment does not make specific limitations on this.

[0087] The beacon signal is a signal that the first UE in the silent waveband actively sends to the network side device, which is used to inform the network side device that the first UE exists in the silent waveband and needs to access the network. The first UE in the silent waveband sends a beacon signal to the network side device to attract the attention of the network side device to the silent waveband, thereby activating the silent waveband and providing access services for the first UE in the silent waveband.

[0088] It should be noted that the beacon signal is sent by the UE to the network side device through a certain modulation method. The beacon signal carries the identification information of the first UE that sends the beacon signal. The identification information of the first UE may include the identity of the first UE, the timestamp of the beacon signal transmission, and other information, so that the network side device can identify the source of the beacon signal. The network side device can demodulate and identify the beacon signal, thereby determining whether the first UE exists in the silent wave position.

[0089] S103: When the network side device detects a beacon signal on the first uplink beam, the network side device determines that the first UE exists in the silent beam position, and converts the silent beam position into an activated beam position.

[0090] Figure 2 A flowchart of another coverage enhancement method provided in an embodiment of the present application is shown below. Figure 2 As shown, after the network side device allocates the first uplink beam to the silent beam position, the network side device needs to determine whether a beacon signal is detected on the first uplink beam.

[0091] If the network side device detects a beacon signal on the first uplink beam, the network side device determines that there is a first UE in the silent beam position. At this time, the network side device converts the silent beam position into an activated beam position and broadcasts access information to the activated beam position so that the first UE can access the network.

[0092] Specifically, after the network side device determines that the first UE exists in the silent wave position, it is also necessary to authenticate the first UE, and after the identity authentication is passed, the silent wave position where the first UE is located is converted into an activated wave position.

[0093] If the network side device does not detect a beacon signal on the first uplink beam, it means that the first UE does not exist in the silent beam position, and the network side device continues to allocate the first uplink beam to the silent beam position.

[0094] The embodiment of the present application provides a coverage enhancement method, in which the network side device configures the wave position in the coverage area of ​​the base station as an activated wave position and / or a silent wave position through preset rules. In the activated wave position, the network side device broadcasts access information to determine whether the UE in the activated wave position can access the network; in the silent wave position, the network side device only detects whether there is a UE in the silent wave position through the first uplink beam to avoid unnecessary downlink broadcasts. If the network side device detects the UE in the silent wave position through the first uplink beam, the network side device converts the wave position from the silent wave position to the activated wave position and broadcasts the access information. Compared with the prior art, the present application introduces an on-demand dynamic management mechanism for activated wave positions and silent wave positions, thereby avoiding broadcasting downlink information in silent wave positions where access services are not required, thereby reducing unnecessary resource consumption, saving network energy, and significantly improving the coverage capability and resource utilization efficiency of the network. Especially in satellite or non-terrestrial network NTN environments with scarce resources and wide coverage, the present application can effectively reduce energy consumption, improve network coverage capability and terminal access efficiency through on-demand activation, and ultimately enhance overall network performance and reduce operating costs.

[0095] In the above embodiment, the network side device needs to configure the target beam position as an active beam position or a silent beam position according to a preset rule. Next, the specific process of configuring the target beam position as an active beam position or a silent beam position according to a preset rule by the network side device is described in detail.

[0096] like Figure 2 As shown, in a possible embodiment, S101, the network side device configures the target wave position as an activated wave position or a silent wave position according to a preset rule, which can be implemented through S1011 to S1013. S1011 and S1013 are described in detail below.

[0097] S1011. The network-side device obtains a predicted probability of the second UE existing in the target wave position based on the target information.

[0098] It should be noted that the first UE in the above embodiment refers to a UE that needs to access the network in a silent wave position, and the first UE has been actually detected by the network side device. The second UE in this embodiment refers to a UE that may exist in the target wave position predicted by the network side device through target information, and the second UE has not yet been actually detected by the network side device.

[0099] In this embodiment, the number of the first UE and the second UE may be one or more. The first UE may be the second UE or a UE newly added in the silent wave position.

[0100] The target information includes at least one of the geographical location information, historical data information and operator information of the target wave position.

[0101] It should be noted that the geographical location information of the target wave position refers to the geographical location of the target wave position on the map. The network side device can predict the probability of the second UE existing in the target wave position according to the geographical location information of the target wave position to obtain the predicted probability.

[0102] For example, the geographic location information indicates that the target wave position is located in a commercial area, and the demand for UE to access the network is high in the commercial area. Therefore, the network side device predicts that the probability that the second UE exists in the target wave position is 90%.

[0103] For another example, the geographic location information indicates that the target wave position is located in a desert. In the desert, the demand for UE to access the network is low. Therefore, the network-side device predicts that the predicted probability of the second UE being present in the target wave position is 0.

[0104] It should be noted that the historical data information of the target wave position refers to the historical activity data of the second UE in the target wave position collected by the network side device. The historical data information may include the access records of all second UEs in the target wave position in a certain time period. Through the historical data information, the network side device can predict the probability of the second UE in the target wave position in the next time period and obtain the predicted probability.

[0105] For example, if a second UE has initiated a network access procedure at the target wavelength in the past period of time, then the network-side device predicts that the probability that the second UE exists at the target wavelength is 100%.

[0106] For another example, if no second UE has initiated a network access process at the target wavelength in the past period of time, then the network-side device predicts that the probability that the second UE exists at the target wavelength is 0.

[0107] It should be noted that the operator information refers to the information of the second UE whose registration location is consistent with the geographical location of the target wave position stored in the operator system. The operator maintains the registration location information of each second UE in its network management system. If the registration location of a second UE is consistent with the geographical location of the target wave position, the identification information of the second UE is recorded in the operator information corresponding to the target wave position, so that the subsequent network side equipment can predict the probability of the second UE existing in the target wave position according to the operator information corresponding to the target wave position and obtain the predicted probability.

[0108] For example, when the identification information of at least one second UE is recorded in the operator information corresponding to the target wave position, the network side device predicts that the probability of the second UE existing in the target wave position is 100%; when the identification information of the UE is not recorded in the operator information corresponding to the target wave position, the network side device predicts that the probability of the second UE existing in the target wave position is 0.

[0109] In this embodiment, the network side device can predict whether there is a UE in the target wave position based on the geographical location information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the historical data information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the operator information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the geographical location information and historical data information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the geographical location information and operator information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the historical data information and operator information corresponding to the target wave position; it can also predict whether there is a UE in the target wave position based on the geographical location information, historical data information and operator information corresponding to the target wave position, and this embodiment does not make any specific limitations on this.

[0110] It should be noted that the network side device can use one or more of the geographic location information, historical data information and operator information of the target wave position as input to the first prediction model, and output the predicted probability of the second UE existing in the target wave position through the first prediction model. The predicted probability of the second UE existing in the target wave position can also be obtained through other methods, which will not be elaborated in this embodiment.

[0111] S1012: When the predicted probability is greater than the first preset probability, the network-side device configures the target wave position as an activated wave position.

[0112] The first preset probability may be set by the network administrator according to the actual network environment and requirements, and this embodiment does not specifically limit this.

[0113] For example, the first preset probability is 80%.

[0114] It should be noted that if the predicted probability is greater than the first preset probability, it means that there is a high possibility that a UE that needs to access the network exists in the target wave position. In order to ensure that the UE in the target wave position can access the network normally, the network side device configures the target wave position as an activated wave position.

[0115] S1013: When the predicted probability is less than or equal to the first preset probability, the network-side device configures the target wave position as a silent wave position.

[0116] It should be noted that if the predicted probability is less than or equal to the first preset probability, it means that the possibility of the existence of a UE that needs to access the network in the target wave position is small. In order to avoid broadcasting downlink information in the target wave position that does not need to provide access service, the network side device configures the target wave position as a silent wave position to reduce unnecessary resource consumption.

[0117] In an embodiment of the present application, the network side device predicts the probability that a second UE may exist in the target wave position based on one or more of the geographic location information, historical data information, and operator information of the target wave position. When the predicted probability is greater than the first preset probability, the network side device configures the target wave position as an activated wave position; when the predicted probability is less than or equal to the first preset probability, the target wave position is configured as a silent wave position, thereby avoiding unnecessary waste of resources. This method effectively improves the utilization efficiency of network resources, reduces unnecessary access broadcasts, thereby saving network energy consumption and optimizing resource allocation, especially in large-scale network deployments, can improve overall network performance, reduce operating costs, and at the same time ensure UE access efficiency.

[0118] In the above embodiment, when the antenna beam corresponding to the base station covers the silent beam position, the network side device needs to allocate the first uplink beam to the silent beam position. Next, the specific process of the network side device allocating the first uplink beam to the silent beam position is described in detail.

[0119] In a possible embodiment, when the predicted probability is greater than the second preset probability and the predicted probability is less than or equal to the first preset probability, the first uplink beam performs beam scanning on the silent wave position based on the first scanning period.

[0120] It should be noted that when the predicted probability obtained by the network side device based on one or more of the geographic location information, historical data information and operator information of the target wave position is less than or equal to the first preset probability, the possibility that there is a second UE that needs to access the network in the target wave position is small, and the network side device configures the target wave position as a silent wave position. Even if the predicted probability is less than or equal to the first preset probability, there may still be a second UE in the silent wave position. Therefore, the network side device allocates the first uplink beam to the silent wave position so that the network side device can detect the beacon signal sent by the second UE (first UE) in the silent wave position.

[0121] In this embodiment, the greater the predicted probability, the greater the possibility that the second UE exists in the silent wave position.

[0122] The second preset probability is less than the first preset probability. The second preset probability can be set by the network administrator according to the actual network environment and requirements, and this embodiment does not specifically limit this.

[0123] For example, the second preset probability is 50%.

[0124] Among them, the network side can determine the first scanning period of the first uplink beam according to the beam resources, energy reserves, wireless resource load and other conditions of the base station.

[0125] It should be noted that, when the base station has more beam resources, sufficient energy reserves, and a smaller wireless resource load, the first uplink beam may be a continuous uplink beam.

[0126] It should be noted that if the predicted probability is greater than the second preset probability, and the predicted probability is less than or equal to the first preset probability, it means that there is a high probability that a second UE exists in the silent wave position. Therefore, the network side device will configure the first uplink beam to perform beam scanning on the silent wave position with a first scanning period, so that the network side device can promptly detect the beacon signal sent by the second UE (first UE) in the silent wave position, thereby quickly converting the silent wave position into an activated wave position to provide access service for the first UE.

[0127] When the predicted probability is less than or equal to the second preset probability, the first uplink beam performs beam scanning on the silent wave position based on the second scanning period.

[0128] The second scanning period is greater than the first scanning period.

[0129] It should be noted that if the predicted probability is less than or equal to the second preset probability, it means that the possibility of the second UE existing in the silent wave position is small. Therefore, the network side device will extend the scanning period of the first uplink beam and configure the first uplink beam to perform beam scanning on the silent wave position with the second scanning period to reduce the energy consumption caused by excessive scanning and optimize the utilization of network resources.

[0130] In an embodiment of the present application, by introducing a dynamic beam scanning strategy based on predicted probability, the resource management of the silent wave position is optimized. When the predicted probability of the second UE existing in the silent wave position is relatively high, the network side device configures the first uplink beam to frequently scan the silent wave position with a shorter first scanning period, so that the network side device can detect the second UE in the silent wave position in time; and when the predicted probability of the second UE existing in the silent wave position is relatively low, the network side device configures the first uplink beam to scan the silent wave position with a second scanning period, and the second scanning period is greater than the first scanning period, thereby reducing the energy consumption caused by excessive scanning. This method effectively balances resource consumption and network performance, improves the timeliness of UE access, avoids unnecessary frequent scanning, saves network resources, and improves overall energy efficiency.

[0131] In the above embodiment, after the network side device configures the target wave position as an activated wave position or a silent wave position according to a preset rule, the network side device needs to allocate access information for the third UE to access the activated wave position. Next, the access information allocated by the network side device to the activated wave position is described in detail.

[0132] like Figure 2 As shown, in a possible embodiment, after S101, the network side device configures the target wave position as an activated wave position or a silent wave position according to a preset rule, the method further includes S104, and S104 is described in detail below.

[0133] S104: When the antenna beam covers the activated beam position, the network-side device allocates a second uplink beam, a downlink beam and wireless resources for access of a third UE to the activated beam position.

[0134] Among them, the third UE is a UE located in the activated wave position.

[0135] In this embodiment, the number of the third UE may be one or more. The third UE may be the second UE or a UE newly added in the activated wave position.

[0136] Among them, the downlink beam includes a synchronization signal.

[0137] It should be noted that when the antenna beam covers the activated wave position, the network side device will allocate the second uplink beam, downlink beam and wireless resources required for the third UE to access the activated wave position to support the third UE in the activated wave position to access the network.

[0138] The second uplink beam is used for the third UE to send data or signals to the network side device, and is usually used for uplink communication.

[0139] The downlink beam is used by the base station to send data or control information to the third UE. The downlink beam includes common channels such as the synchronization signal SS, the physical broadcast channel PBCH, and the system information block SIB.

[0140] In addition to the second uplink beam and downlink beam, the network-side equipment also needs to allocate other wireless resources to the activated beam, such as frequency resources, time slot resources, power allocation, etc., to ensure the effectiveness and quality of data transmission.

[0141] It should be noted that the specific contents of the second uplink beam, downlink beam and wireless resources allocated by the network side device for the activated wave position for the third UE access are the same as the specific contents of the uplink beam, downlink beam and wireless resources used for UE access in the prior art, and will not be repeated in this embodiment.

[0142] In an embodiment of the present application, the network side device ensures that the third UE in the activated wave position can complete network access and two-way communication in a timely manner by allocating a second uplink beam, a downlink beam and wireless resources in the activated wave position, especially providing a synchronization signal through the downlink beam.

[0143] In the above embodiment, after the network side device allocates the second uplink beam, downlink beam and wireless resources for the third UE to access the activated beam, the network side device may also convert the activated beam into the silent beam. Next, the specific process of the network side device converting the activated beam into the silent beam is described in detail.

[0144] like Figure 2 As shown, in a possible embodiment, in S104, when the antenna beam covers the activated wave position, after the network side device allocates a second uplink beam, a downlink beam and wireless resources for access of a third UE to the activated wave position, the method also includes S105, and S105 is described in detail below.

[0145] S105: When there is no third UE in the RRC connected state in the activated beam position within the first preset time period, the network side device converts the activated beam position into a silent beam position.

[0146] After the network side device allocates the second uplink beam, downlink beam and wireless resources for the access of the third UE to the activated wave position, the network side device needs to determine whether there is a third UE in the radio resource control (Radio Resource Control, RRC) connection state in the activated wave position within the first preset time length.

[0147] If the network side device determines that there is no third UE in RRC connected state in the activated wave position within the first preset time length, it means that there is no third UE initiating access and / or communication process in the activated wave position within the first preset time length. At this time, the network side device converts the activated wave position into a silent wave position, and the network side device only allocates the first uplink beam to the silent wave position.

[0148] If the network side device determines that there is a UE in RRC connected state in the activated wave position within the first preset time length, it means that there is a third UE initiating an access or communication process in the activated wave position, and the network side device continues to allocate a second uplink beam, downlink beam and wireless resources to the activated wave position.

[0149] It should be noted that the method by which the network-side device determines whether there is a UE in an RRC-connected state in the activated wave position within the first preset time length is an existing method and will not be described in detail in this embodiment.

[0150] The first preset duration may be set by the network administrator according to the actual network environment and requirements, and this embodiment does not specifically limit this.

[0151] For example, the first preset duration is 1 minute.

[0152] In the implementation of the present application, when no UE access or UE communication process occurs in the activated wave position within the first preset time period, the network side device converts the activated wave position into a silent wave position, thereby reducing the ineffective consumption of beams, energy and wireless resources, and optimizing the use of network resources. Especially in the non-terrestrial network NTN environment with large-scale coverage and high-efficiency management, it can effectively save energy and concentrate limited resources on areas with actual business needs, thereby enhancing the network's coverage capability and overall performance.

[0153] In the above embodiment, when the antenna beam covers the activated beam, the network side device needs to allocate the second uplink beam and the downlink beam to the activated beam. Next, the specific process of the network side device allocating the second uplink beam and the downlink beam to the activated beam is described in detail.

[0154] In a possible embodiment, when the predicted traffic volume value corresponding to the activated beam position is greater than the set traffic volume value, the second uplink beam and the downlink beam perform beam scanning on the activated beam position based on the third scanning period.

[0155] The traffic volume prediction value is used to indicate the predicted communication traffic volume of the third UE in the activated wave position.

[0156] It should be noted that after the network side device configures the target wave position as the activated wave position, the network side device can also output the predicted communication traffic of the third UE in the activated wave position in the next time period through the second prediction model based on the geographic location information, historical data information and operator information of the target wave position.

[0157] In this embodiment, the greater the predicted traffic volume value is, the more network resources the UE in the activated wave position needs to occupy.

[0158] It should be noted that the service volume setting value can be set by the network administrator according to the actual network environment and requirements, and this embodiment does not make any specific limitation to this.

[0159] Among them, the network side can determine the third scanning period of the second uplink beam and the downlink beam according to the beam resources, energy reserves, wireless resource load and other conditions of the base station.

[0160] It should be noted that, when the base station has more beam resources, sufficient energy reserves, and less wireless resource load, the second uplink beam can be a continuous uplink beam, and the downlink beam can also be a continuous downlink beam.

[0161] It should be noted that if the predicted traffic volume value is greater than the set traffic volume value, it means that the communication traffic of the third UE in the activated wave position is large. Therefore, the network side device will configure the second uplink beam and the downlink beam to perform beam scanning on the activated wave position with a third scanning period, so as to respond to the communication needs of the third UE in the activated wave position in time.

[0162] When the predicted traffic volume value is less than or equal to the set traffic volume value, the second uplink beam and the downlink beam perform beam scanning on the activated beam position based on the fourth scanning period.

[0163] The fourth scanning period is greater than the third scanning period.

[0164] It should be noted that if the predicted traffic volume value is less than or equal to the set traffic volume value, it means that the communication traffic of the UE in the activated wave position is small. Therefore, the network side equipment will extend the scanning period of the second uplink beam and the downlink beam, and configure the second uplink beam and the downlink beam to perform beam scanning on the activated wave position with the fourth scanning period to save energy and resource consumption.

[0165] In an embodiment of the present application, by introducing a dynamic beam scanning strategy based on a predicted traffic volume, the resource management of the activated wave position is optimized. By predicting the communication needs of the third UE in the activated wave position, the network side device can adjust the frequency and period of the second uplink beam and downlink beam scanning. If the predicted communication traffic volume in the activated wave position is large (that is, the predicted traffic volume value is greater than the set traffic volume value), the network side device will select a shorter third scanning period to perform beam scanning on the activated wave position, thereby frequently detecting the activated wave position in order to respond to the communication needs of the third UE in the activated wave position in a timely manner; if the predicted communication traffic volume in the activated wave position is small (that is, the predicted traffic volume value is less than or equal to the set traffic volume value), the network side device will select a longer fourth scanning period to scan the activated wave position, reduce the scanning frequency, and save energy and resource consumption. Through this dynamic adjustment strategy, the network side device can reasonably allocate resources according to different communication needs, improve resource utilization efficiency, optimize network performance, and avoid unnecessary frequent beam scanning, reducing energy consumption.

[0166] Figure 3 A flowchart of another coverage enhancement method provided in an embodiment of the present application is shown below. Figure 3 As shown, another coverage enhancement method provided in an embodiment of the present application specifically includes S301 to S309, and S301 to S309 are described in detail below.

[0167] Among them, the executor of the coverage enhancement method provided in the embodiment of the present application is UE.

[0168] S302: The UE detects a synchronization signal sent by a network-side device.

[0169] The UE is located at a target beam position, which is any beam position within the coverage area of ​​the base station.

[0170] It should be noted that the target beam position may be an activated beam position or a silent beam position. When the target beam position is a silent beam position, the UE is a first UE; when the target beam position is an activated beam position, the UE is a third UE.

[0171] like Figure 3 As shown, before S302, the UE detects the synchronization signal sent by the network side device, the method also includes S301, and S301 is described in detail below.

[0172] S301. UE initializes its internal counters and timers.

[0173] It should be noted that the counter is used to track the number of times the UE sends a beacon signal. Before the UE accesses the network, the UE needs to initialize the counter that affects subsequent operations and clear the counter to ensure that the subsequent counting and control logic will not be affected by the previous state.

[0174] The timer is used to track the cumulative duration of beacon signals sent by the UE. By initializing the timer and clearing the timer to zero, it can be ensured that the timer can accurately reflect the current state of the UE in a new connection or communication attempt.

[0175] In addition, the UE also needs to clear its internal cache data to ensure that outdated cache data is not used during the UE's network access process to avoid errors or delays caused by cache data. The cache data may include network configuration information, previous access information, access point lists, etc.

[0176] It should be noted that the UE is triggered to initialize its internal counter and timer, thereby triggering the UE to start executing the method steps shown in the above S302.

[0177] In this embodiment, the UE can be triggered by a preset sleep timer to initialize its internal counters and timers, or by an application to trigger the UE to initialize its internal counters and timers, or by a user manually triggering the UE to initialize its internal counters and timers, which is not specifically limited in this embodiment.

[0178] It should be noted that the UE usually enters a sleep state when it is idle. At this time, the UE control system will set a sleep timer. When the sleep timer reaches the timing time, the UE will actively wake up and initialize its internal counters and timers.

[0179] It should be noted that, in some cases, the application on the UE may actively request to access the network. When the application on the UE actively requests to access the network, the UE will be triggered to initialize its internal counters and timers.

[0180] It should be noted that in some scenarios, especially when the UE is in a non-terrestrial network environment (such as satellite communication, ocean, remote areas, etc.), the UE may not need to maintain a continuous connection with the network. The user can manually choose when to access the network to trigger the UE to initialize its internal counters and timers. The user manually triggering the UE to access the network has important practical value for saving UE power, avoiding unnecessary network resource consumption, and reducing communication costs.

[0181] In the method steps shown in S302, the method for UE to detect the synchronization signal sent by the network side device is an existing method, which will not be described in detail in this implementation.

[0182] S303: Determine whether the UE detects a synchronization signal within a second preset time period.

[0183] When the UE detects the synchronization signal sent by the network side device, the UE needs to determine whether it detects the synchronization signal sent by the network side device within the second preset time length.

[0184] The second preset duration may be agreed upon through a protocol or may be set by the UE itself, and this embodiment does not specifically limit this.

[0185] It should be noted that the second preset duration defines the maximum duration for the UE to wait for the synchronization signal when the UE does not send a beacon signal. During the second preset duration, the UE will continue to detect whether the network side device sends a synchronization signal.

[0186] If the UE detects the synchronization signal within the second preset time period, the UE no longer continues to detect the synchronization signal, and the UE directly accesses the network based on the detected synchronization signal.

[0187] If the UE fails to detect the synchronization signal within the second preset time period, it means that the target wave position where the UE is located has been configured as a silent wave position by the network side device. At this time, the UE will send a beacon signal to the network side device. Correspondingly, the network side device receives the beacon signal sent by the UE. The network side device determines that the first UE exists in the target wave position based on the beacon signal. The network side device converts the target wave position from a silent wave position to an activated wave position, and allocates a second uplink beam, downlink beam and wireless resources for access by the first UE (third UE) to the target wave position, so that the third UE can subsequently detect the synchronization signal.

[0188] In this embodiment, by setting the second preset duration, the waiting time, resource utilization and energy efficiency management of the UE can be optimized while ensuring the access success rate, avoiding resource waste caused by too long waiting, and ensuring that the UE can send beacon signals to the network side device in a timely manner, thereby improving the efficiency and success rate of the access process.

[0189] It should be noted that when the UE determines that it has detected a synchronization signal within the second preset time length, the UE executes the method steps shown in S304; when the UE determines that it has not detected a synchronization signal within the second preset time length, the UE executes the method steps shown in S305.

[0190] S304: When the UE detects the synchronization signal within the second preset time period, control the UE to access the network based on the synchronization signal.

[0191] Among them, when the UE detects the synchronization signal within the second preset time period, it means that the target wave position where the UE is located is configured as an activated wave position by the network side device, and the UE is a third UE. The network side device provides the activated wave position with a second uplink beam, downlink beam and wireless resources for the third UE to access. At this time, the third UE can access the network based on the synchronization signal.

[0192] It should be noted that the method for the third UE to access the network based on the synchronization signal is an existing method and will not be described in detail in this embodiment.

[0193] S305: When the UE fails to detect a synchronization signal within a second preset time period, determine whether the UE meets a beacon signal sending condition.

[0194] Among them, when the target wave position is a silent wave position, the network side device allocates the first uplink beam to the silent wave position, and the UE does not detect the synchronization signal within the second preset time length; the first uplink beam is used by the network side device to detect the beacon signal sent by the UE in the silent wave position.

[0195] It should be noted that the process of the network-side device allocating the first uplink beam to the target wave position when the target wave position is a silent wave position has been described in the above embodiment and will not be repeated in this embodiment.

[0196] Among them, the beacon signal sending conditions are pre-set.

[0197] It should be noted that, when the UE meets the beacon signal sending conditions, the UE executes the method steps shown in S306; when the UE does not meet the beacon signal sending conditions, the UE executes the method steps shown in S307.

[0198] S306: When the UE meets the beacon signal sending condition, the UE sends a beacon signal to the network side device.

[0199] The UE sends a beacon signal to the network side device so that the network side device determines that the UE exists in the target wave position and converts the target wave position from a silent wave position to an activated wave position.

[0200] It should be noted that the content of the beacon signal has been described in the above embodiment and will not be repeated in this embodiment.

[0201] After S306, the UE executes the method steps shown in S308.

[0202] S308: Determine whether the UE detects a synchronization signal within a third preset time period.

[0203] The UE may be a simplex UE or a duplex UE.

[0204] It should be noted that for a simplex UE, the UE cannot detect the synchronization signal while sending a beacon signal, and can detect the synchronization signal only after the UE sends the beacon signal. For a duplex UE, the UE can detect the synchronization signal while sending a beacon signal.

[0205] In order to ensure the universality of the method, after the UE sends a beacon signal to the network side device, the UE needs to wait for a third preset time length and detect the synchronization signal within the third preset time length.

[0206] The third preset duration may be agreed upon through a protocol or may be set by the UE itself, and this embodiment does not specifically limit this.

[0207] For example, the third preset time length is 3 seconds.

[0208] It should be noted that the third preset duration defines the maximum duration for the UE to wait for the synchronization signal after the UE sends a beacon signal. The third preset duration may be the same as or different from the second preset duration, and this embodiment does not specifically limit this.

[0209] Within the third preset time period, the UE will continue to detect the synchronization signal. If the UE detects the synchronization signal within the third preset time period, the UE executes the method steps shown in S309; ​​if the UE does not detect the synchronization signal within the third preset time period, the UE returns to execute the method steps shown in the above S305 to determine whether the UE meets the beacon signal sending conditions, and sends the beacon signal again when the beacon signal conditions are met, thereby effectively increasing the UE's chance of accessing the network in a silent wave position and improving the probability of successful UE access, especially when the signal is unstable or the synchronization signal cannot be detected in time, by multiple attempts to send the beacon signal, the network side device's perception of the UE's presence is enhanced, so that the silent wave position can be converted into an activated wave position, thereby optimizing network coverage and resource utilization, and avoiding access failure due to a single detection failure.

[0210] S309: When the UE detects the synchronization signal within a third preset duration, control the UE to access the network based on the synchronization signal.

[0211] It should be noted that if the UE detects the synchronization signal within the third preset time length, it means that the network side device has received the beacon signal sent by the UE. The network side device determines that there is a UE in the target wave position and converts the target wave position from a silent wave position to an activated wave position.

[0212] In this embodiment, the method for the third UE to access the network based on the synchronization signal is an existing method, which will not be described in detail in this embodiment.

[0213] S307: When the UE does not meet the beacon signal sending condition, control the UE to enter a sleep state.

[0214] It should be noted that after the UE enters the sleep state, it can be triggered manually by a preset sleep timer, an application program or a user, and after being triggered, the UE executes the method steps shown in the above S301 again.

[0215] In this embodiment, when the UE does not meet the beacon signal sending condition, it enters the sleep state, which can avoid unnecessary signal sending and communication processes, thereby effectively saving the battery power of the UE.

[0216] In an embodiment of the present application, for a UE in a target wave position, the UE detects a synchronization signal sent by a network side device. If the UE detects the synchronization signal within a second preset time period, the UE accesses the network based on the synchronization signal. If the UE does not detect the synchronization signal within the second preset time period, it is determined whether the UE meets the beacon signal sending condition, and if the UE meets the beacon signal sending condition, a beacon signal is sent to the network side device to notify the network side device of the existence of the UE in the target wave position through the beacon signal, prompting the network side device to convert the target wave position from a silent wave position to an activated wave position, and provide access services for the target wave position, so that the UE can access the network. The method of this embodiment effectively solves the problem that UEs in silent wave positions are difficult to be discovered, improves the success rate of UE access, shortens access delay, and optimizes network resource allocation. It is particularly suitable for scenarios with limited signal coverage such as non-terrestrial networks such as NTN, and improves the coverage capability and service efficiency of the network.

[0217] In the above embodiment, before sending a beacon signal each time, it is necessary to determine whether the UE meets the beacon signal sending condition. Next, the beacon signal sending condition is described in detail.

[0218] In a possible embodiment, the beacon signal sending conditions include that the cumulative number of times the UE sends a beacon signal is less than a preset number, the cumulative duration of the UE sending a beacon signal is less than a fourth preset duration, and there is at least one beacon frequency point in the beacon frequency point table that the beacon signal has not traversed.

[0219] The beacon frequency table includes at least one beacon frequency.

[0220] It should be noted that the beacon frequency table is agreed upon by the UE and the network side device through standard specifications. The beacon frequency table may include one beacon frequency or multiple beacon frequencies, which is not specifically limited in this embodiment.

[0221] When the beacon frequency table includes only one beacon frequency, the UE only needs to send a beacon signal at this beacon frequency, and the network side device only needs to detect the beacon signal sent by the UE at this beacon frequency.

[0222] In the case where the beacon frequency table includes multiple beacon frequencies, the network side device can use any one of the following three methods to determine whether a beacon signal is detected. First, the UE selects any beacon frequency in the beacon frequency table to send a beacon signal, and the network side device simultaneously detects multiple beacon frequencies included in the beacon frequency table, for example, by collecting and processing broadband signals containing multiple beacon frequencies, and analyzing whether a beacon signal appears at each beacon frequency. Second, the UE sends beacon signals in sequence at the multiple beacon frequencies included in the beacon frequency table, and the network side device considers that the UE is found when it detects any beacon signal. Third, the UE uses the multiple beacon frequencies included in the beacon frequency table to send beacon signals according to a preset frequency hopping mode, and the network side device considers that the UE is found when it detects a beacon signal at any beacon frequency, or the network side device considers that the UE is found when it detects that the beacon signal meets the agreed frequency hopping mode.

[0223] It should be noted that in the silent wave position, since the UE cannot obtain the synchronization signal, the uplink beacon signal is also sent asynchronously. When the network side device detects the beacon signal by time division multiplexing (in turns, scanning), the length of time each UE sends a beacon signal each time should be greater than the scanning period of the network side device to detect the beacon signal, so as to prevent the UE from sending a beacon signal in a certain silent wave position while the network side device is in the process of detecting other silent wave positions and cannot detect the beacon signal.

[0224] It should be noted that in the same silent wave position, the beacon signals sent by multiple UEs may overlap with each other. When the network-side device uses the signal correlation algorithm to detect the beacon signal, it can detect multiple correlation peaks, and it can also be determined that the UE has been found. In areas or frequency bands with less interference signals, or when the false detection requirements are not high, the network-side device can also use a simple signal power detection algorithm to achieve a relatively rough UE discovery, thereby greatly reducing the complexity of the network-side device detection algorithm.

[0225] The network-side device and the UE agree on the beacon signal sequence and / or waveform through standard specifications. For example, the modulation and waveform of the beacon signal can be combined with one or more of the following methods: single-frequency signal, amplitude modulation (Amplitude Modulation, AM), frequency modulation (Frequency Modulation, FM), pulse code modulation (Pulse Code Modulation, PCM), phase shift keying (Phase Shift Keying, PSK), frequency shift keying (Frequency Shift Keying, FSK), amplitude shift keying (Amplitude Shift Keying, ASK), Gaussian minimum shift keying (Gaussian Minimum Shift Keying, GMSK), frequency modulated signal (Chirp Signal), quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM), continuous phase modulation (Continuous Phase Modulation, CPM), minimum shift keying (Minimum Shift Keying, MSK), as well as orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) and code division multiple access (Code Division Multiple Access, CDMA) and other methods. The signal sequence may be an M sequence or a Zadoff–Chu sequence, etc., which is not specifically limited in this embodiment.

[0226] The cumulative number of times the UE sends a beacon signal refers to the cumulative number of times the UE sends a beacon signal after initializing its internal counter and timer.

[0227] It should be noted that the preset number of times may be agreed upon through a protocol or may be set by the UE itself, and this embodiment does not specifically limit this.

[0228] For example, the preset number of times is 10 times.

[0229] In order to prevent the UE from sending beacon signals to the network side device too frequently, thereby causing unnecessary energy consumption and resource occupation, an upper limit of the preset number is set. As long as the cumulative number of times the UE sends beacon signals has not reached the preset number, the UE can continue to send beacon signals to the network side device until the cumulative number of times the UE sends beacon signals reaches the preset number.

[0230] The cumulative duration of beacon signal transmission by the UE refers to the cumulative duration of beacon signals transmitted by the UE after the UE completes initialization of its internal counter and timer.

[0231] It should be noted that the fourth preset duration may be agreed upon through a protocol or may be set by the UE itself, and this embodiment does not specifically limit this.

[0232] For example, the fourth preset time length is 30 seconds.

[0233] By setting the fourth preset duration, it can be ensured that the transmission of the beacon signal will not take too long, thereby affecting other communication tasks or causing unnecessary network resource consumption. In this way, when the UE sends a beacon signal, its duration will be controlled within a reasonable range to efficiently utilize network resources.

[0234] The existence of beacon frequencies in the beacon frequency table that are not traversed by the beacon signal means that the traversal of the beacon signal has not yet covered all beacon frequencies in the beacon frequency table.

[0235] It should be noted that when the traversal of the beacon signal does not cover all beacon frequencies in the beacon frequency table, the UE can continue to send beacon signals on the remaining untraversed beacon frequencies to ensure that the UE can scan multiple beacon frequencies to increase the chance of the UE sending a beacon signal to the network side device and avoid wasting beacon frequency resources.

[0236] In this embodiment, the beacon signal sending condition may be that the cumulative number of times the UE sends a beacon signal is less than a preset number; it may also be that the cumulative duration of the UE sending a beacon signal is less than a fourth preset duration; it may also be that there is a beacon frequency point in the beacon frequency point table that the beacon signal has not traversed; it may also be that the cumulative number of times the UE sends a beacon signal is less than the preset number, and the cumulative duration of the UE sending a beacon signal is less than the fourth preset duration; it may also be that the cumulative number of times the UE sends a beacon signal is less than the preset number, and there is a beacon frequency point in the beacon frequency point table that the beacon signal has not traversed; it may also be that the cumulative duration of the UE sending a beacon signal is less than the fourth preset duration, and there is a beacon frequency point in the beacon frequency point table that the beacon signal has not traversed; it may also be that the cumulative number of times the UE sends a beacon signal is less than the preset number, the cumulative duration of the UE sending a beacon signal is less than the fourth preset duration, and there is a beacon frequency point in the beacon frequency point table that the beacon signal has not traversed. This embodiment does not make specific limitations on this.

[0237] In an embodiment of the present application, by introducing a mechanism for determining the beacon signal sending conditions, the beacon signal sending strategy of the UE when the synchronization signal is not detected is further optimized. By limiting the cumulative number of beacon signal sending times, the cumulative sending duration, and the use of beacon frequencies that have not been traversed in the beacon frequency table, the UE can actively send a beacon signal to the network side device to notify it of its existence and request access when the beacon signal sending conditions are met. This method avoids unnecessary frequent sending and waste of resources, effectively reduces the energy consumption of the UE, and at the same time improves the effectiveness of the beacon signal and the detection success rate. In particular, in scenarios with poor network coverage or limited resources, this method can significantly improve the response efficiency of the network side device to the UE, ensure efficient use of communication resources, and optimize the UE access success rate and access delay.

[0238] In the above embodiment, for a duplex UE, the UE can detect the synchronization signal while sending a beacon signal. Next, another way for a duplex UE to send a beacon signal is described in detail.

[0239] In a possible embodiment, when the UE is a duplex UE, in S308, in the process of determining whether the UE detects a synchronization signal within a third preset time length, the method further includes: within the target time period when the UE does not detect the synchronization signal, the UE repeats the method steps in S305 to determine whether the UE meets the beacon signal sending conditions.

[0240] Among them, the target time period belongs to the third preset time length.

[0241] In a possible implementation, when the UE detects the synchronization signal within a third preset duration, the target time period refers to a time period between a start time of the third preset duration and a time when the UE detects the synchronization signal.

[0242] In another possible implementation, when the UE fails to detect the synchronization signal within a third preset duration, the target time period refers to the third preset duration.

[0243] In an embodiment of the present application, for a duplex UE, by allowing the UE to determine whether the UE meets the beacon signal sending conditions while detecting the synchronization signal, and sending a beacon signal to the network side device when the UE meets the beacon signal sending conditions, the UE avoids wasting time in the process of detecting the synchronization signal, enables the UE to flexibly respond to different network environments and requirements, optimizes resource utilization, and improves the dynamic response capability of the network.

[0244] In another possible embodiment, when the UE is a duplex UE, when the UE sends a beacon signal to a network side device, as long as the UE detects a synchronization signal, the UE immediately stops sending the beacon signal to the network side device and accesses the network based on the detected beacon signal.

[0245] It should be noted that, in the actual implementation process, the network side device may delay sending the synchronization signal based on the beacon signal sent by the UE last time due to network delay, or the network side device may allocate the synchronization signal to the silent wave position due to the beacon signal sent by other UEs in the silent wave position where the UE is located, so that the UE accidentally receives the synchronization signal when sending the beacon signal. At this time, the UE will immediately stop sending the beacon signal and access the network based on the detected synchronization signal.
