Description

Information processing method, terminal equipment, base station, device and medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410177361.7 and invention name “Information processing method, terminal equipment, base station, device and medium”, the entire contents of which are incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to an information processing method, terminal equipment, base station, apparatus, and medium. Background Art

[0003] Satellite communication systems use satellites as relay stations to forward microwave signals and communicate between multiple ground stations. The main purpose of satellite communication is to achieve "seamless" coverage of the ground. Due to the long distance between the satellite and the ground, satellites generally use narrow beams for signal transmission. However, since the angle of coverage of each beam is limited, in order to facilitate random access and other services for users corresponding to different beams in the cell, the satellite-borne base station usually uses beam scanning to cover the service range of the entire cell. Beam scanning refers to the use of beams in different directions to send physical signals or reference signals at different times. A cell usually needs to send multiple synchronization signal blocks (SSBs) to complete a beam scan so that the synchronization signal covers the entire service range of the cell.

[0004] Currently, beam configuration information is configured at the cell level. This means that beams in different cells have different configuration information, but all beams within the same cell have the same configuration information. However, cell-level configuration cannot adapt to the actual communication scenarios and requirements of all beams within the cell, which may lead to poor communication performance and affect user experience. Summary of the Invention

[0005] The embodiments of the present disclosure provide an information processing method, terminal device, base station, apparatus, and medium for resolving the problem that existing cell-level configuration cannot adapt to the actual communication scenarios and requirements corresponding to all beams in the cell, which may lead to poor communication performance and affect user experience.

[0015] Based on the downlink message, obtain the configuration information corresponding to the current beam where the terminal device is located.

[0016] The present disclosure also provides a base station, including:

[0017] A memory for storing a computer program; a transceiver for transmitting and receiving data under the control of a processor; and a processor for reading the computer program in the memory and performing the following operations:

[0021] A first receiving module is configured to receive a downlink message sent by a base station, wherein the downlink message is used to indicate information corresponding to configurations of different beams within a cell;

[0022] The first acquisition module is used to obtain information corresponding to the configuration of the current beam where the terminal device is located based on the downlink message.

[0023] The present disclosure also provides an information processing device, including:

[0026] An embodiment of the present disclosure further provides a computer-readable storage medium, wherein the storage medium stores a computer program, and the computer program is used to execute the information processing method provided by the embodiment of the present disclosure.

[0027] In the disclosed embodiments, a terminal device is capable of receiving a downlink message sent by a base station, wherein the downlink message indicates information about the configurations corresponding to different beams within a cell. The terminal device then obtains information about the configuration corresponding to the current beam in which the terminal device is located based on the downlink message. With the above technical solution, the beam configuration information is beam-level configuration, meaning that different beam configurations within the same cell can have different information. This makes the beam configuration information more flexible and more aligned with actual communication scenarios and requirements corresponding to the beams, thereby improving communication performance and enhancing the user experience.

[0062] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0063] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0064] As used herein, the term "including" and its variations are open-ended, i.e., "including but not limited to." The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments." Other terms are defined in the following description.

[0065] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0066] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0067] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0068] Through research, the applicant discovered that all beams within the same cell have the same configuration information. This information includes various aspects, including: SSB transmit power, SSB transmission period, SSB transmission status indication, SI broadcast status, SI transmission period, SIB-to-SI mapping, resource configuration information for MSG1 requesting non-broadcast SI, paging period, paging opportunity, and paging location information. The following uses SSB transmit power as an example for illustration.

[0069] For example, Figure 1 is a schematic diagram of the correspondence between SSB transmit power and cells. As shown in Figure 1, the SSB transmit powers of cell PCI0, cell PCI1, cell PCI2, cell PCI3, cell PCI4, cell PCI5, and cell PCI6 are SSB transmit power 0, SSB transmit power 1, SSB transmit power 2, SSB transmit power 3, SSB transmit power 4, SSB transmit power 5, and SSB transmit power 6, respectively. That is, the SSB transmit power of different cells is different, but the SSB transmit power of all beams in the same cell is the same.

[0070] In satellite communication systems, cells are large and contain a large number of beams. Therefore, the distances between different beams within the same cell can be considerable. Consequently, the channel conditions for different beams vary significantly. Therefore, the same SSB transmit power within the same cell cannot meet the actual communication scenarios and requirements for all beams. For example, different beams within the same cell have different beam distances. Specifically, some beams within the same cell may be located near the subsatellite point, meaning the beam-to-satellite distance is close and path loss is low; while others may have a smaller elevation angle relative to the satellite, meaning the beam-to-satellite distance is far and path loss is high. If all beams have the same SSB transmit power, users on distant beams will experience lower SSB receive power, impacting SSB decoding performance on terminal devices. Since SSB detection is a critical step in the random access process, poor SSB decoding performance can severely impact the user's communication experience, leading to issues such as access latency. The same applies to other factors, such as beam traffic density and beam priority, and will not be discussed further here.

[0071] Furthermore, onboard resources are extremely expensive. Effectively utilizing them can improve the performance of the entire satellite communication system and make it more economically competitive compared to other communication methods. Transmit power, as an onboard resource, must be used efficiently and effectively. In the NTN system, satellites use a single spot beam for time-sharing scanning, meaning they only serve a specific area at a time. When multiple areas request service, they can only be served based on priority, resulting in long communication response delays and impacting user experience. To address this issue, satellites will likely adopt a multi-beam operating mechanism in the future, meaning that multiple spot beams can be illuminated simultaneously to serve different areas. This will greatly increase the flexibility of satellite communication systems and reduce communication latency. However, onboard power resources are already extremely scarce, and the transmit power of a single beam is inevitably affected. Therefore, how to allocate power among multiple spot beams is also a challenge that needs to be addressed.

[0072] FIG2 is a flow chart of an information processing method provided by an embodiment of the present disclosure. The method can be executed by an information processing device, wherein the device can be implemented using software and / or hardware and can generally be integrated into a terminal device. The terminal device involved in the embodiment of the present disclosure can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called User Equipment (UE). A wireless terminal device can be a USB storage device, other personal computer memory device, and a dongle. It can also communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablet computers, Machine-type Communication (MTC) terminal devices, etc. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, but are not limited in the embodiments of the present disclosure.

[0073] As shown in FIG2 , the method includes:

[0074] S210. Receive a downlink message sent by a base station, where the downlink message is used to indicate information corresponding to configurations of different beams within a cell.

[0075] In an embodiment of the present disclosure, the terminal device can receive a downlink message sent by the base station, so as to obtain information corresponding to the configuration of the current beam where the terminal device is located based on the downlink message.

[0076] It should be noted that, in a satellite communication system scenario, different beams within a cell may be beams transmitted by a satellite through a single spot beam mechanism or a multi-spot beam mechanism, but is not limited thereto.

[0077] Specifically, the beam includes: a beam direction, a logical service range or coverage area at the system level, or a logical beam index at the system level, but is not limited thereto.

[0078] Specifically, there are many specific forms of expression of the information corresponding to the beam configuration. Typical examples are described below, but they do not constitute a limitation of the present disclosure.

[0079] In some embodiments, the downlink message is used to indicate information corresponding to configurations of different beams within a cell, including: the downlink message is used to indicate information related to SSB corresponding to configurations of different beams within the cell; and / or,

[0080] The downlink message is used to indicate information related to SIBs configured for different beams within the cell; and / or,

[0081] The downlink message is used to indicate the paging-related information corresponding to the configuration of different beams within the cell.

[0082] Specifically, the information related to SSB may include SSB transmission power, SSB transmission period, and / or SSB transmission status indication, but is not limited thereto.

[0083] Specifically, the information related to SIBs may include SI broadcast status, SI transmission period, SIB to SI mapping relationship, and / or resource configuration information of MSG1 for requesting non-broadcast SI, but is not limited thereto.

[0084] Specifically, the information related to paging may include paging cycle, paging opportunity, paging location information, etc., but is not limited thereto.

[0085] Specifically, the configuration information corresponding to different beams can be allocated by the core network, base station, etc., but is not limited to this.

[0086] Specifically, the configuration information corresponding to different beams can be set according to the actual communication scenarios and requirements of different beams.

[0087] In some embodiments, the configuration information corresponding to different beams within a cell is determined based on the different "service requirements within the beam (service distribution and / or user volume), beam service priority, distance between the beam and the base station (or path loss), specific requirements for each system information, different requirements for different system messages, and / or paging requirements" of different beams.

[0088] For example, different SSB transmit powers are configured at the beam level based on the distance of different beams from the base station and / or the service requirements within the beam. For example, the SSB transmit power of a beam farther from the base station is higher than that of a beam closer to the base station; and the SSB transmit power of a beam with greater service requirements within the beam is higher than that of a beam with less service requirements within the beam.

[0089] Different SSB transmission periods are configured at the beam level based on the intra-beam service requirements, beam service priorities, and / or channel quality of different beams. For example, the SSB transmission period of a beam with a high intra-beam service requirement is shorter than that of a beam with a low intra-beam service requirement; and the SSB transmission period of a beam with a high beam service priority is shorter than that of a beam with a low beam service priority.

[0090] For SSB transmission status indication, different SSB transmission status indications are configured at the beam level based on the intra-beam service demand, beam service priority, and / or channel quality of different beams. For example, beams with high intra-beam service demand may have more SSB transmission status indications than beams with low intra-beam service demand; and beams with high beam service priority may have more SSB transmission status indications than beams with low beam service priority.

[0091] For the SI sending period, different SI sending periods are configured at the beam level according to the specific requirements of different beams for each system information.

[0092] For the SI broadcast status, different SI broadcast statuses are configured at the beam level according to the specific requirements of different beams for each system information, that is, some beams are not allowed to receive broadcast SIBs, and some beams cannot receive the broadcast SIBs.

[0093] Regarding the mapping relationship between SIBs and SI, different mapping relationships between SIBs and SI are configured at the beam level according to the different requirements of different beams for different system messages.

[0094] For the MSG1 resource configuration of SIBs for requesting SIB messages, different MSG1 resource configurations for requesting SIB messages are configured at the beam level according to different requirements of different beams for different system messages.

[0095] For paging cycles (or paging occasions), different paging cycles (or paging occasions) are configured at the beam level according to the specific paging requirements of different beams.

[0096] Specifically, the downlink message can be any message that can "indicate information corresponding to the configuration of different beams within the cell." The downlink message can be expressed in various forms, for example, the downlink message can include a SIB1 (System Information Block type 1) message or an RRC (Radio Resource Control) message, but is not limited thereto.

[0097] Specifically, the downlink message may indicate information corresponding to the configuration of at least one beam within at least one cell, wherein the "at least one cell" includes the current cell where the terminal device is located, and the "at least one beam" includes the current beam corresponding to the terminal device.

[0098] In some examples, the downlink message is used to indicate information corresponding to the configuration of different beams in the current cell; or, the downlink message is used to indicate information corresponding to the configuration of the current beam.

[0099] S220. Obtain configuration information corresponding to the current beam where the terminal device is located based on the downlink message.

[0100] In the embodiment of the present disclosure, since the downlink message is used to indicate the configuration information corresponding to different beams in the cell, the terminal device can obtain the configuration information corresponding to the current beam where the terminal device is located based on the downlink message.

[0101] As shown above, there are many specific forms of information corresponding to the beam configuration. The following describes in detail how to obtain the information corresponding to the current beam configuration of the terminal device based on the downlink message, including SSB transmission power, SSB transmission period, SSB transmission status indication, SI broadcast status, SI transmission period, SIB to SI mapping relationship, resource configuration information of MSG1 for requesting non-broadcast SI, paging period, paging timing and paging location information, but it does not constitute a limitation of the present disclosure.

[0102] Case 1: SSB transmit power

[0103] Information related to SSB includes: SSB transmit power configured for different beams within the cell. At this time, the specific content included in the downlink message and the specific implementation methods for obtaining the SSB transmit power corresponding to the current beam based on the downlink message include but are not limited to the following:

[0104] Method 1

[0105] The downlink message includes a power extension array, and the SSB transmission power corresponding to the current beam is obtained from the power extension array. As shown in Figure 3, the method includes:

[0106] S310: Receive a downlink message sent by a base station, wherein the downlink message includes a power extension array. The power extension array is used to represent the SSB transmission power corresponding to each beam in the cell.

[0107] Specifically, the length of the power extension array can be set according to actual conditions and is not limited thereto.

[0108] In some embodiments, the length of the power extension array can be smaller than the total number of beams in the cell. Each element in the power extension array corresponds to an SSB transmit power, and one SSB transmit power corresponds to at least one beam. This reduces the amount of data in the power extension array, which helps reduce the resource usage of the power extension array for downlink messages.

[0109] In other embodiments, the length of the power extension array may be equal to the total number of beams in the cell. Each element in the power extension array corresponds to an SSB transmit power, and one SSB transmit power corresponds to one beam. In this way, there is a one-to-one correspondence between the beams in the current cell and the SSB transmit powers in the power extension array, i.e., each beam independently corresponds to an SSB transmit power, which helps improve the flexibility and accuracy of SSB transmit power settings.

[0110] In some further implementations, the length of the power extension array may be greater than the total number of beams in the cell, some elements in the power extension array are SSB transmission powers, and some elements are empty, and one SSB transmission power corresponds to one beam.

[0111] In one example, the downlink message includes: a SIB1 message, wherein the length of the power extension array is determined based on signaling overhead.

[0112] For example, when SIB1 is used to carry the power extension array, the length of the power extension array in SIB1 can be 8 to match the ssb-PositionsInBurst format in SIB1. Determining the length of the power extension array based on signaling overhead allows the length of the power extension array to match the signaling overhead, thereby ensuring efficient transmission of SIB1 messages carrying the power extension array.

[0113] In another example, the downlink message includes: an RRC message, wherein the length of the power extension array is determined based on the total number of beams of the current cell.

[0114] For example, when RRC signaling is used to carry a power extension array, in order to match the ssb-PositionsInBurst format in the RRC signaling, the power extension array does not need to be indicated in a compressed manner. If the total number of beams in the current cell is less than or equal to a first number (for example, 4), shortPowerList is used to indicate the SSB transmit power. In this case, the length of the power extension array is shorter. If the total number of beams in the current cell is less than or equal to a second number (for example, 8), mediumPowerList is used to indicate the SSB transmit power. In this case, the length of the power extension array is medium, where the second number is greater than the first number. If the total number of beams in the current cell is less than or equal to a second number (for example, 64), longPowerList is used to indicate the SSB transmit power. In this case, the length of the power extension array is longer, where the third number is greater than the first number. Determining the length of the power extension array based on the total number of beams in the current cell is beneficial for enabling more beams in the current cell to correspond one-to-one with the SSB transmit powers in the power extension array, thereby improving the flexibility and accuracy of SSB transmit power settings.

[0115] S320: Based on the pre-acquired current beam identifier, determine the target position corresponding to the current beam identifier from the power extension array.

[0116] In the embodiments of the present application, there are various specific forms of beam identification. For example, the beam identification may include an SSB index for identifying the SSB corresponding to the beam, or a beam index for identifying the beam, etc., but is not limited to this.

[0117] The current beam identifier is the beam identifier corresponding to the current beam. For example, the current beam identifier may include the current SSB index or the current beam index. The current SSB index is used to identify the SSB corresponding to the current beam of the terminal device, and the current beam index is used to identify the current beam of the terminal device.

[0118] Specifically, there are many specific implementation methods for obtaining the current beam identifier. The following is an example of the current beam identifier being the current SSB index.

[0119] In some embodiments, the process of obtaining the current SSB index includes: performing a cell search, decoding a received SSB signal to obtain the current SSB index;

[0120] Alternatively, obtain the current SSB index sent by the base station, core network, or other terminal devices.

[0121] Specifically, there are many specific implementations for determining the "target position corresponding to the current beam identifier", including but not limited to:

[0122] In some embodiments, the target position corresponding to the current beam identifier is determined from the power expansion array based on a pre-acquired correspondence relationship, where the correspondence relationship is the relationship between the position of the element in the power expansion array and the beam identifier. This allows the target position corresponding to the beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0123] In other embodiments, the target position corresponding to the current beam identifier is determined from the power extension array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0124] Specifically, the index order may include from left to right, or from right to left, etc., but is not limited thereto.

[0125] In some examples, the length of the power extension array may be smaller than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the power extension array. The "remainder + 1" (or "remainder") position in the power extension array is then determined as the target position according to the pre-acquired index sequence.

[0126] In other examples, the length of the power extension array may be equal to the total number of beams in the cell. In this case, the "beam ID + 1" (or "current beam ID") position in the power extension array is determined as the target position according to the pre-acquired index order.

[0127] In some other examples, the length of the power extension array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the power extension array is determined as the target position according to the pre-acquired index order.

[0128] The following describes this with two detailed examples.

[0129] Example 1: When SIB1 is used to carry the power extension array, in order to match the ssb-PositionsInBurst format in SIB1, the length of the power extension array in SIB1 can be 8. If the total number of beams in the current cell is 64, the SSBs of the 64 beams will be divided into 8 groups, with 8 SSBs in each group, that is, SSB0-7 belong to the first group, SSB8-15 belong to the second group, and so on. The 8 bits in groupPresence represent whether all SSBs in each group are transmitted. The 8 bits in inOneGroup represent whether the 8 SSBs in the group are transmitted. In order to save the signaling overhead of SIB1, there is naturally no need to waste resources to indicate the SSB transmission power of the SSB that is not actually transmitted. In a power extension array of length 8, the first SSB transmit power on the left represents the SSB transmit power of SSB0 / 8 / 16 / 24 / 32 / 40 / 48 / 56 / 64, the second SSB transmit power on the left represents the SSB transmit power of SSB1 / 9 / 17 / 25 / 33 / 41 / 49 / 57, and so on. The eighth SSB transmit power on the left represents the SSB transmit power of SSB7 / 15 / 23 / 31 / 39 / 47 / 55 / 63. If the total number of beams in the current cell is 8, all eight SSB transmit powers in the power extension array are valid. The first SSB transmit power on the left represents the SSB transmit power of SSB0, the second SSB transmit power on the left represents the SSB transmit power of SSB1, and so on. The eighth SSB transmit power on the left represents the SSB transmit power of SSB7. If the total number of beams in the current cell is 4, only the 4 SSB transmit powers on the left are valid in the power extension array, and the terminal device can ignore the 4 elements on the right. The first SSB transmit power on the left represents the SSB transmit power of SSB0, the second SSB transmit power on the left represents the SSB transmit power of SSB1, ..., and so on. The fourth SSB transmit power on the left represents the SSB transmit power of SSB3.

[0130] In a second exemplary embodiment, when RRC signaling is used to carry a power extension array, in order to match the ssb-PositionsInBurst format in the RRC signaling, if the total number of beams in the current cell is 64, longPowerList is used to indicate the SSB transmit power. Then, the first SSB transmit power on the left side of the power extension array represents the SSB transmit power of SSB0, the second SSB transmit power on the left side represents the SSB transmit power of SSB1, ..., and so on. The 64th SSB transmit power on the left side represents the SSB transmit power of SSB63. If the total number of beams in the current cell is 8, mediumPowerList is used to indicate the SSB transmit power. Then, the first SSB transmit power on the left side of the power extension array represents the SSB transmit power of SSB0, the second SSB transmit power on the left side represents the SSB transmit power of SSB1, ..., and so on. The eighth SSB transmit power on the left side represents the SSB transmit power of SSB7. If the total number of beams in the current cell is 4, shortPowerList is used to indicate the SSB transmit power. The first SSB transmit power on the left side of the power extension array represents the SSB transmit power of SSB0, the second SSB transmit power on the left side represents the SSB transmit power of SSB1, ..., and so on. The fourth SSB transmit power on the left side represents the SSB transmit power of SSB3.

[0131] S330. Obtain the SSB transmission power corresponding to the current beam from the target position.

[0132] Specifically, the SSB transmit power at the target position in the power extension array is the SSB transmit power corresponding to the current beam.

[0133] It is understood that the downlink message includes a power extension array, so that the SSB transmit power corresponding to the current beam can be directly obtained from the power extension array based on the current beam identifier. This makes the acquisition of the SSB transmit power corresponding to the current beam simple and fast, which helps save computing resources of the terminal device. In addition, the power extension array is used to represent the SSB transmit power corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the power extension array to re-acquire the SSB transmit power corresponding to the new beam.

[0134] Method 2

[0135] The downlink message includes a reference SSB transmit power and a power offset array. The SSB offset value corresponding to the current beam is obtained from the power offset array. Then, the SSB transmit power corresponding to the current beam is obtained based on the reference SSB transmit power and the SSB offset value corresponding to the current beam. As shown in Figure 4, the method includes:

[0136] S410. Receive a downlink message sent by the base station, wherein the downlink message includes: a reference SSB transmit power, and a power offset array, where the power offset array is used to represent an SSB offset value of the SSB transmit power corresponding to each beam in the cell relative to the reference SSB transmit power.

[0137] Specifically, those skilled in the art may set the length of the power offset array according to actual conditions, and this is not limited.

[0138] In some embodiments, the length of the power offset array can be less than the total number of beams in the cell. Each element in the power offset array represents an SSB offset value, and each SSB offset value corresponds to at least one beam. The power offset array has a small data size, which helps reduce the resource usage of the power offset array for downlink messages.

[0139] In other embodiments, the length of the power offset array can be equal to the total number of beams in the cell. Each element in the power offset array is an SSB offset value, and each SSB offset value corresponds to a beam. The beams in the current cell correspond one-to-one to the SSB offset values ​​in the power offset array, meaning each beam independently corresponds to an SSB offset value. This improves the flexibility and accuracy of SSB offset setting.

[0140] In some further implementations, the length of the power offset array may be greater than the total number of beams in the cell, some elements in the power offset array are SSB offset values, and some elements are empty, and one SSB offset value corresponds to one beam.

[0141] In one example, the downlink message includes a SIB1 message. In some embodiments, the length of the power offset array is determined based on signaling overhead. This can be understood by referring to "The length of the power offset array is determined based on signaling overhead" and will not be further described here.

[0142] In another example, the downlink message includes an RRC message. In some embodiments, the length of the power offset array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power offset array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0143] S420. Based on the pre-acquired current beam identifier, obtain the SSB offset value corresponding to the current beam from the power offset array.

[0144] Specifically, the downlink message is parsed to obtain the reference SSB transmit power and power offset array.

[0145] Specifically, based on the pre-acquired current beam identifier, a target position corresponding to the current beam identifier is determined from the power offset array; and an SSB offset value corresponding to the current beam is obtained from the target position.

[0146] Specifically, there are many specific implementations for determining the "target position corresponding to the current beam identifier", including but not limited to:

[0147] In some embodiments, the target position corresponding to the current beam identifier is determined from the power offset array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the pre-acquired power offset array and the beam identifiers. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0148] In other embodiments, the target position corresponding to the current beam identifier is determined from the power offset array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0149] In some examples, the length of the power offset array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam ID by the length of the power offset array. The "remainder + 1" (or "remainder") position in the power offset array is then determined as the position corresponding to the current beam ID, using the pre-acquired index sequence.

[0150] In other examples, the length of the power offset array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the power offset array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0151] In yet other examples, the length of the power offset array may be greater than the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the power offset array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0152] Specifically, the SSB offset value at the target position in the power offset array is the SSB offset value corresponding to the current beam.

[0153] S430. Obtain the SSB transmit power corresponding to the current beam according to the reference SSB transmit power and the SSB offset value corresponding to the current beam.

[0154] Specifically, there are many specific forms of expression of the SSB offset value, and various specific implementation methods of "obtaining the SSB transmission power corresponding to the current beam based on the reference SSB transmission power and the SSB offset value corresponding to the current beam". Typical examples are described below, but do not constitute a limitation of the present disclosure.

[0155] In some embodiments, the power offset array includes: an offset value array represented by decibel milliwatts dBm, wherein the power offset value array respectively indicates the offset value of the SSB transmission power corresponding to each beam relative to the reference SSB transmission power.

[0156] Correspondingly, S430 includes: calculating the reference SSB transmit power and the offset value corresponding to the current beam in dBm, and obtaining the SSB transmit power corresponding to the current beam.

[0157] Specifically, the sum of the reference SSB transmit power and the offset value (in dBm) corresponding to the current beam is calculated to obtain the SSB transmit power corresponding to the current beam. That is, the SSB transmit power corresponding to the current beam = the reference SSB transmit power + the offset value (in dBm) corresponding to the current beam.

[0158] It can be understood that using dBm as the power unit of the offset value facilitates comparison and calculation of power levels, and is more intuitive and easier to understand than using linear units (such as watts), and can better describe and analyze the power level of SSB in wireless communications.

[0159] In some other embodiments, the power offset array includes: an offset value array represented by decibels dB, wherein the power offset value array respectively indicates the offset value of the SSB transmission power corresponding to each beam relative to the reference SSB transmission power.

[0160] Correspondingly, S430 includes: calculating the reference SSB transmit power and the offset value corresponding to the current beam in dB, and obtaining the SSB transmit power corresponding to the current beam.

[0161] In one example, the offset value array indicates the attenuation value of the SSB transmit power corresponding to each beam relative to the reference SSB transmit power. Accordingly, S430 includes calculating the reference SSB transmit power and the attenuation value corresponding to the current beam in dB, and obtaining the SSB transmit power corresponding to the current beam.

[0162] Specifically, the reference SSB transmit power is divided by the attenuation value in dB corresponding to the current beam to obtain the SSB transmit power corresponding to the current beam. That is, the SSB transmit power corresponding to the current beam = the reference SSB transmit power / the attenuation value in dB corresponding to the current beam.

[0163] In another example, the offset value array respectively indicates the elevation value of the SSB transmission power corresponding to each beam relative to the reference SSB transmission power. Accordingly, S430 includes: calculating the reference SSB transmission power and the elevation value corresponding to the current beam in dB, and obtaining the SSB transmission power corresponding to the current beam.

[0164] Specifically, the product of the reference SSB transmit power and the boost value (in dB) corresponding to the current beam is calculated to obtain the SSB transmit power corresponding to the current beam. That is, the SSB transmit power corresponding to the current beam = the reference SSB transmit power * the boost value (in dB) corresponding to the current beam.

[0165] It is understandable that dB can represent a wide range of values ​​using smaller values, so that the data volume of the offset value array can be smaller, which is beneficial to reducing the resource occupation of the offset value array for downlink messages.

[0166] In some further embodiments, the power offset array includes: an offset step expressed in decibel milliwatts dBm and an offset step factor array, wherein the offset step factor array respectively indicates the offset step factor of the SSB transmission power corresponding to each beam relative to the reference SSB transmission power.

[0167] Correspondingly, S430 includes: calculating the reference SSB transmit power, the offset step in dBm and the offset step factor corresponding to the current beam, and obtaining the SSB transmit power corresponding to the current beam.

[0168] Specifically, the product of the offset step size in dBm and the offset step size factor corresponding to the current beam is calculated, and the sum of this product and the reference SSB transmit power is calculated to obtain the SSB transmit power corresponding to the current beam. That is, the SSB transmit power corresponding to the current beam = the reference SSB transmit power + the offset step size factor corresponding to the current beam * the offset step size in dBm.

[0169] It can be understood that using dBm as the power unit of the offset step can make the offset step more intuitive and easy to understand, and using the offset step and offset step factor array in decibel milliwatts dBm to represent the power offset array can make the values ​​of the offset step and the offset step factor smaller, thereby making the data volume of the power offset array smaller, which is beneficial to the resource occupation of the power offset array for downlink messages.

[0170] In some further embodiments, the power offset array includes: an offset step expressed in decibels (dB) and an offset step factor array, wherein the offset step factor array respectively indicates the offset step factor of the SSB transmission power corresponding to each beam relative to the reference SSB transmission power.

[0171] Correspondingly, S430 includes: calculating the reference SSB transmit power, the offset step in dB and the offset step factor corresponding to the current beam, and obtaining the SSB transmit power corresponding to the current beam.

[0172] Specifically, the product of the offset step factor corresponding to the current beam and the offset step size in decibels (dB) is calculated, the product is divided by 10 to the first power, and the product of the reference SSB transmit power and 10 to the first power is calculated to obtain the SSB transmit power corresponding to the current beam. That is, the SSB transmit power corresponding to the current beam = reference SSB transmit power * (10^((offset step factor corresponding to the current beam * offset step size in decibels (dB)) / 10)).

[0173] It can be understood that the offset step and offset step factor array in decibels dB represents the power offset array, which can make the values ​​of the offset step and the offset step factor smaller. In this way, the amount of data in the power offset array can be smaller, which is beneficial to reducing the resource occupation of the power offset array for downlink messages.

[0174] In addition, the power offset array is used to represent the SSB offset value of the SSB transmission power corresponding to each beam in the cell sent by the base station relative to the reference SSB transmission power, so that even if the terminal device switches to a new beam, it can continue to use the power offset array to re-obtain the SSB offset value corresponding to the new beam.

[0175] Of course, the downlink message can also include a reference SSB transmit power and an SSB offset value corresponding to the current beam. The SSB transmit power corresponding to the current beam can be obtained based on the reference SSB transmit power and the SSB offset value corresponding to the current beam.

[0176] It is understandable that the downlink message includes the reference SSB transmit power and the SSB offset value corresponding to the current beam, but does not include the SSB offset values ​​corresponding to other beams, so that the resource occupation of the downlink message is relatively small. In addition, the numerical value of the SSB offset value is relatively small, which is conducive to further reducing the resource occupation of the downlink message.

[0177] Method 3:

[0178] The downlink message includes the SSB transmission power corresponding to the current beam. The SSB transmission power corresponding to the current beam can be obtained by parsing the downlink message.

[0179] As shown in FIG5 , the method includes:

[0180] S510. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: the SSB transmission power corresponding to the current beam.

[0181] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0182] S520. Analyze the downlink message to obtain the SSB transmission power corresponding to the current beam.

[0183] It can be understood that the downlink message includes the SSB transmit power corresponding to the current beam, but does not include the SSB transmit power corresponding to other beams, which reduces the resource usage of the downlink message. Furthermore, carrying the SSB transmit power corresponding to the current beam in the downlink message is similar to carrying the SSB transmit power corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the SSB transmit power corresponding to the current cell can be replaced with the SSB transmit power corresponding to the current beam without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0184] In some embodiments, the method further includes: receiving a downlink message sent by the base station for a new beam after beam switching for the terminal device, and parsing to obtain the SSB transmission power corresponding to the new beam.

[0185] Specifically, the downlink message corresponding to the new beam includes the SSB transmit power corresponding to the new beam. Therefore, obtaining and parsing the downlink message corresponding to the new beam can obtain the SSB transmit power corresponding to the new beam. After switching to the new beam, the terminal device can obtain the SSB transmit power corresponding to the new beam to adapt to the actual communication scenario and needs corresponding to the new beam.

[0186] In the disclosed embodiment, the SSB transmit power is configured at the beam level, that is, different beams within the same cell can be configured with different SSB transmit powers, making the configuration of the SSB transmit power more flexible, which is conducive to matching the SSB transmit power with the actual communication scenarios and requirements corresponding to the corresponding beam, thereby improving communication performance and enhancing user experience.

[0187] In another embodiment of the present disclosure, the method further comprises:

[0188] Get the SSB received power corresponding to the current beam;

[0189] Estimate the path loss corresponding to the current beam based on the SSB receive power and the SSB transmit power corresponding to the current beam;

[0190] According to the path loss corresponding to the current beam, the uplink power control value corresponding to the current beam is obtained.

[0191] It can be understood that by determining the path loss corresponding to the current beam based on the SSB transmit power and SSB receive power corresponding to the current beam, and obtaining the uplink power control value corresponding to the current beam based on the path loss corresponding to the current beam, the uplink power control value can be matched with the path loss, thereby enabling the terminal device to receive better quality signals and improve communication quality.

[0192] Case 2: SSB sending cycle

[0193] Information related to SSB includes: the SSB transmission period configured for different beams within the cell (i.e., ssb-PeriodicityServingCell). At this time, there are many specific implementation methods for the specific content included in the downlink message and for obtaining the SSB transmission period corresponding to the current beam based on the downlink message. The following is an explanation of a typical example.

[0194] Method 1

[0195] The downlink message includes a period extension array, and the SSB transmission period corresponding to the current beam is obtained from the period extension array. As shown in Figure 6, the method includes:

[0196] S610. Receive a downlink message sent by a base station, wherein the downlink message includes: a period extension array, and the period extension array is used to represent the SSB transmission period corresponding to each beam in the cell.

[0197] Specifically, the length of the periodic extension array can be set according to actual conditions and is not limited thereto.

[0198] In some embodiments, the length of the period extension array can be less than the total number of beams in the cell. Each element in the period extension array represents an SSB transmission period, and an SSB transmission period corresponds to at least one beam. The period extension array has a smaller data size, which helps reduce the resource usage of the period extension array for downlink messages.

[0199] In other embodiments, the length of the period extension array may be equal to the total number of beams in the cell. Each element in the period extension array represents an SSB transmission period, and each SSB transmission period corresponds to one beam. The beams in the current cell correspond one-to-one to the SSB transmission periods in the period extension array, meaning each beam independently corresponds to an SSB transmission period. This improves the flexibility and accuracy of SSB transmission period setting.

[0200] In some further implementations, the length of the period extension array may be greater than the total number of beams of the cell, some elements in the period extension array are SSB transmission periods, and some elements are empty, and one SSB transmission period corresponds to one beam.

[0201] In one example, the downlink message includes a SIB1 message, wherein the length of the period extension array is determined based on signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on signaling overhead” and will not be further described here.

[0202] In another example, the downlink message includes an RRC message, wherein the length of the period extension array is determined based on the total number of beams in the current cell. For reference, the length of the power extension array is determined based on the total number of beams in the current cell, and is not further described here.

[0203] S620: Determine a target position corresponding to the current beam identifier from the period extension array based on the pre-acquired current beam identifier.

[0204] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0205] Specifically, there are many specific implementations for determining the "target position corresponding to the current beam identifier", including but not limited to:

[0206] In some embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the periodic extension array and the beam identifiers. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0207] In other embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0208] In some examples, the length of the periodic extension array may be smaller than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the periodic extension array. The "remainder + 1" (or "remainder") position in the periodic extension array is then determined as the target position according to the pre-acquired index sequence.

[0209] In other examples, the length of the periodic extension array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the periodic extension array is determined as the target position according to the pre-acquired index order.

[0210] In some other examples, the length of the periodic extension array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the periodic extension array is determined as the target position according to the pre-acquired index order.

[0211] S630. Obtain the SSB transmission period corresponding to the current beam from the target position.

[0212] Specifically, the SSB transmission period at the target position in the period extension array is the SSB transmission period corresponding to the current beam.

[0213] It is understood that the downlink message includes a period extension array, so that the SSB transmission period corresponding to the current beam can be directly obtained from the period extension array based on the current beam identifier. This makes the acquisition of the SSB transmission period corresponding to the current beam simple and fast, which helps save computing resources of the terminal device. In addition, the period extension array is used to represent the SSB transmission period corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the period extension array to re-acquire the SSB transmission period corresponding to the new beam.

[0214] Method 2

[0215] The downlink message includes a reference SSB transmission period and a period multiple array. The period multiple corresponding to the current beam is obtained from the period multiple array. Then, the SSB transmission period corresponding to the current beam is obtained based on the reference SSB transmission period and the period multiple corresponding to the current beam. As shown in Figure 7, the method includes:

[0216] S710. Receive a downlink message sent by the base station, wherein the downlink message includes: a reference SSB transmission period, and a period multiple array, where the period multiple array is used to represent the period multiples of the SSB transmission period corresponding to each beam in the cell relative to the reference SSB transmission period.

[0217] Specifically, the length of the period multiple array can be set according to actual conditions and is not limited thereto.

[0218] In some embodiments, the length of the period multiples array can be less than the total number of beams in the cell. Each element in the period multiples array represents a period multiple, and each period multiple corresponds to at least one beam. The period multiples array has a smaller data size, which helps reduce the resource usage of the period multiples array for downlink messages.

[0219] In other embodiments, the length of the period multiple array can be equal to the total number of beams in the cell. Each element in the period multiple array represents a period multiple, and each period multiple corresponds to a beam. Beams within the current cell correspond one-to-one to the period multiples in the period multiple array, meaning each beam independently corresponds to a period multiple. This improves the flexibility and accuracy of period multiple setting.

[0220] In some further implementations, the length of the period multiple array may be greater than the total number of beams of the cell, some elements in the period multiple array are period multiples, some elements are empty, and one period multiple corresponds to one beam.

[0221] In one example, the downlink message includes a SIB1 message. In some embodiments, the length of the period multiple array is determined based on signaling overhead. This can be understood by referring to "The length of the power extension array is determined based on signaling overhead" and will not be further described here.

[0222] In another example, the downlink message includes an RRC message. In some embodiments, the length of the period multiple array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power extension array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0223] S720: Obtain a period multiple corresponding to the current beam from a period multiple array based on a pre-acquired current beam identifier.

[0224] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0225] Specifically, the downlink message is parsed to obtain a reference SSB sending period and a period multiple array.

[0226] Specifically, based on the pre-acquired current beam identifier, a target position corresponding to the current beam identifier is determined from a period multiple array; and a period multiple corresponding to the current beam is acquired from the target position.

[0227] Specifically, there are many specific implementations for determining the "target position corresponding to the current beam identifier", including but not limited to:

[0228] In some embodiments, the target position corresponding to the current beam identifier is determined from the period multiples array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the pre-acquired period multiples array and the beam identifier. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0229] In other embodiments, the target position corresponding to the current beam identifier is determined from the period multiple array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0230] In some examples, the length of the period multiples array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam ID by the length of the period multiples array. The "remainder + 1" (or "remainder") position in the period multiples array is then determined as the position corresponding to the current beam ID according to the pre-acquired index sequence.

[0231] In other examples, the length of the period multiples array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the period multiples array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0232] In yet other examples, the length of the period multiples array may be greater than the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the period multiples array is determined as the position corresponding to the current beam identifier according to the pre-acquired index sequence.

[0233] Specifically, the period multiple at the target position in the period multiple array is the period multiple corresponding to the current beam.

[0234] S730. Obtain the SSB transmission period corresponding to the current beam based on the reference SSB transmission period and the period multiple corresponding to the current beam.

[0235] Specifically, the product of the reference SSB transmission period and the period multiple corresponding to the current beam is calculated to obtain the SSB transmission period corresponding to the current beam. That is, the SSB transmission period corresponding to the current beam = the reference SSB transmission period * the period multiple corresponding to the current beam.

[0236] It can be understood that a smaller value for the period multiplier reduces the amount of data in the period multiplier array, which helps reduce the resource usage of the period multiplier array for downlink messages. Furthermore, the period multiplier array is used to represent the period multiplier of the SSB transmission period corresponding to each beam within the cell, sent by the base station, relative to the reference SSB transmission period. This allows the terminal device to continue to use the period multiplier array to retrieve the period multiplier corresponding to the new beam even if it switches to a new beam.

[0237] Method 3

[0238] The downlink message may also include a reference SSB transmission period and a period multiple corresponding to the current beam. The SSB transmission period corresponding to the current beam is obtained based on the reference SSB transmission period and the period multiple corresponding to the current beam. As shown in Figure 8, the method includes:

[0239] S810. Receive a downlink message sent by the base station, wherein the downlink message includes: a reference SSB transmission period, and a period multiple corresponding to a current beam of the terminal device.

[0240] In some embodiments, the period multiple is configured in the signaling containing the reference SSB transmission period.

[0241] In other embodiments, the period multiple is configured in the spare bits of the PBCH.

[0242] Exemplarily, the period multiple is configured in the spare 2 bits of the PBCH, but is not limited thereto.

[0243] Specifically, the downlink message is parsed to obtain the reference SSB transmission period and the period multiple corresponding to the current beam of the terminal device.

[0244] S820. Obtain the SSB transmission period corresponding to the current beam based on the reference SSB transmission period and the period multiple corresponding to the current beam.

[0245] Specifically, the understanding of S820 can refer to S730, which will not be repeated here.

[0246] It is understandable that the downlink message includes the reference SSB transmission period and the period multiple corresponding to the current beam, but does not include the period multiples corresponding to other beams, which reduces the resource usage of the downlink message. In addition, the values ​​of the reference SSB transmission period and period multiple are relatively small, which helps further reduce the resource usage of the downlink message.

[0247] Method 4

[0248] The downlink message includes the SSB transmission period corresponding to the current beam. The SSB transmission period corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 9, the method includes:

[0249] S910. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: an SSB transmission period corresponding to the current beam.

[0250] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0251] S920. Analyze the downlink message to obtain the SSB transmission period corresponding to the current beam.

[0252] It can be understood that the downlink message includes the SSB transmission period corresponding to the current beam, but does not include the SSB transmission periods corresponding to other beams, which reduces the resource usage of the downlink message. In addition, carrying the SSB transmission period corresponding to the current beam in the downlink message is similar to carrying the SSB transmission period corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the SSB transmission period corresponding to the current cell can be replaced with the SSB transmission period corresponding to the current beam without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0253] Case 3: SSB transmission status indication

[0254] Information related to SSB includes: SSB transmission status indications for different beams within the cell. There are various ways to specify the content of the downlink message and obtain the SSB transmission status indication corresponding to the current beam based on the downlink message. Typical examples are described below.

[0255] Method 1:

[0256] The downlink message includes an SSB transmission status indication corresponding to the current beam. The SSB transmission status indication corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 10, the method includes:

[0257] S1010. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: an indication of the SSB transmission status corresponding to the current beam.

[0258] Specifically, the SSB transmission status indication (ie, ssb-PositionsInBurst) is used to indicate whether the SSB is actually sent.

[0259] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0260] S1020. Parse the downlink message to obtain the SSB transmission status indication corresponding to the current beam.

[0261] It can be understood that the downlink message includes the SSB transmission status indication corresponding to the current beam, so that the terminal device can accurately know the SSB transmission status indication corresponding to the current beam. In addition, the downlink message does not include the SSB transmission status indication corresponding to other beams, so that the resources occupied by the downlink message are relatively small.

[0262] Method 2:

[0263] The downlink message includes a transmission indication array, and the SSB transmission status indication corresponding to the current beam is obtained from the transmission indication array. As shown in Figure 11, the method includes:

[0264] S1110. Receive a downlink message sent by a base station, wherein the downlink message includes: a transmission indication array, wherein the transmission indication array is used to indicate an SSB transmission status indication corresponding to each beam in the cell.

[0265] Specifically, the length of the transmission indication array can be set by those skilled in the art according to actual conditions, and is not limited thereto. Some typical examples are described below, but do not constitute a limitation of the present disclosure.

[0266] In some embodiments, the length of the transmission indication array can be less than the total number of beams in the cell. Each element in the transmission indication array represents an SSB transmission status indicator, and each SSB transmission status indicator corresponds to at least one beam. The transmission indication array has a small data size, which helps reduce the resource usage of the transmission indication array for downlink messages.

[0267] In other embodiments, the length of the transmission indication array may be equal to the total number of beams in the cell. Each element in the transmission indication array represents an SSB transmission status indicator, and each SSB transmission status indicator corresponds to one beam. There is a one-to-one correspondence between beams in the current cell and SSB transmission status indicators in the transmission indication array, meaning that each beam independently corresponds to an SSB transmission status indicator. This improves the flexibility and accuracy of SSB transmission status indicator settings.

[0268] In some further implementations, the length of the transmission indication array may be greater than the total number of beams of the cell, some elements in the transmission indication array are SSB transmission status indications, and some elements are empty, and one SSB transmission status indication corresponds to one beam.

[0269] In one example, the downlink message includes: a SIB1 message. In some embodiments, the length of the transmission indication array is determined based on signaling overhead.

[0270] For example, the length of ssb-PositionsInBurst in the SIB1 message is extended from 16 bits to 64 bits in FR2, which is used to accurately indicate the SSB transmission status of each beam in the cell.

[0271] Understandably, in existing protocols, the SSB transmission status indication carried in the SIB1 message is simplified in FR2 to save bit overhead. This is achieved by grouping the SSBs within the burst to indicate the SSB transmission status. In satellite communication system scenarios, given the particularities of satellite communication systems, the beams under the satellite vary significantly, and the accuracy requirements for SSB transmission status indications can be higher than on the ground. Therefore, in FR2, 64 bits can be used to accurately indicate the SSB transmission status of each beam within the cell, improving the accuracy of SSB transmission status indications.

[0272] In another example, the downlink message includes an RRC message. In some embodiments, the length of the transmission indication array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power extension array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0273] S1120. Determine a target position corresponding to the current beam identifier from the transmission indication array based on the pre-acquired current beam identifier.

[0274] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0275] Specifically, the downlink message is parsed to obtain a transmission indication array.

[0276] Specifically, there are many specific implementation methods for determining the "target position corresponding to the current beam identifier", which are described below with reference to typical examples, but do not constitute a limitation to the present disclosure.

[0277] In some embodiments, the target position corresponding to the current beam identifier is determined from the transmission indication array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of the elements in the pre-acquired transmission indication array and the current beam identifier. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0278] In other embodiments, the target position corresponding to the current beam identifier is determined from the transmission indication array based on the current beam identifier according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0279] In some examples, the length of the transmission indication array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the transmission indication array. The "remainder + 1" (or "remainder") position in the transmission indication array is then determined as the position corresponding to the current beam identifier according to the pre-acquired index sequence.

[0280] In other examples, the length of the transmission indication array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the transmission indication array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0281] In some other examples, the length of the transmission indication array may be greater than the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the transmission indication array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0282] Specifically, the SSB transmission status indication at the target position in the transmission indication array is the SSB transmission status indication corresponding to the current beam.

[0283] S1130. Obtain an SSB transmission status indication corresponding to the current beam from the target position.

[0284] Specifically, the SSB transmission status indication at the target position in the transmission indication array is the SSB transmission status indication corresponding to the current beam.

[0285] It can be understood that the transmission indication array is used to represent the SSB transmission status indication corresponding to each beam in the cell sent by the base station, so that even if the terminal device switches to a new beam, it can continue to use the transmission indication array to re-obtain the SSB transmission status indication corresponding to the new beam.

[0286] It can be seen that when the service requirements, beam service priorities, and / or distances from the base station in different beams in the same cell are different, the SSB-related information in the existing protocol (including SSB transmission power, SSB sending period, and / or SSB transmission status indication, etc.) only supports cell-level configuration, that is, the SSB-related information of different beams in the same cell is the same, and it is impossible to differentiate the SSB-related information for different beams based on the differences in the service requirements, beam service priorities, and / or distances from the base station of different beams.

[0287] In the disclosed embodiments, flexible beam-level configuration of SSB-related information is supported, which is conducive to achieving, for example, providing higher SSB transmission power for beams that are far away from the base station, have large business demands within the beam, and have high beam business priorities, and providing smaller SSB transmission power for beams that are close to the base station, have small business demands within the beam, and have low beam business priorities; providing shorter SSB transmission periods and more SSB transmission status indications for beams with large business demands within the beam and high beam business priorities, thereby allowing these beams to have more random access opportunities or more RRM measurements; providing longer SSB periods and fewer SSB transmission status indications for beams with small business demands and low business priorities, thereby avoiding waste of time-frequency domain resources and improving time-frequency domain resource utilization.

[0288] Case 4: SI broadcast status (i.e. si-BroadcastStatus)

[0289] Information related to SIBs includes: the SI broadcast status configured corresponding to different beams in the cell, and the SI corresponding to the SIBs. The existing protocol stipulates that other SIB system messages (such as SIB2-SIB21) and posSIBs system messages except SIB1 will be carried on the SI message, that is, these SIB information are first mapped to the SI message, and then periodically sent through the SI message. Each SIB message will only be mapped to a certain SI message. The SI message is sent within the periodic SI window. Each SI message is associated with an SI window. The SI windows corresponding to different SI messages do not overlap with each other. The SI window length corresponding to different SI messages is fixed. In an SI window, only the SI message associated with it will be sent. This associated SI message can be transmitted repeatedly within the SI window. At this time, there are many specific contents included in the downlink message, and there are many specific implementation methods for obtaining the SI broadcast status corresponding to the current beam based on the downlink message. The following is an explanation of a typical example.

[0290] Method 1

[0291] The downlink message includes the SI broadcast status corresponding to the current beam. The SI broadcast status corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 12, the method includes:

[0292] S1210. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: an SI broadcast status corresponding to the current beam.

[0293] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0294] S1220. Parse the downlink message to obtain the SI broadcast status corresponding to the current beam.

[0295] It can be understood that the downlink message includes the SI broadcast status corresponding to the current beam, but does not include the SI broadcast status corresponding to other beams, which reduces the resource usage of the downlink message. In addition, carrying the SI broadcast status corresponding to the current beam in the downlink message is similar to carrying the SI broadcast status corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the SI broadcast status corresponding to the current cell can be replaced with the SI broadcast status corresponding to the current beam without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0296] Method 2

[0297] The downlink message includes a broadcast status array, and the SI broadcast status corresponding to the current beam is obtained from the broadcast status array. As shown in Figure 13, the method includes:

[0298] S1310. Receive a downlink message sent by a base station, where the downlink message includes: a broadcast status array, where the broadcast status array is used to represent the SI broadcast status corresponding to each beam in the cell.

[0299] Specifically, the length of the broadcast status array is set according to actual conditions and is not limited thereto.

[0300] In some embodiments, the length of the broadcast status array can be smaller than the total number of beams in the cell. Each element in the broadcast status array represents an SI broadcast status, and each SI broadcast status corresponds to at least one beam. The smaller the data size of the broadcast status array, the smaller the resource usage of the broadcast status array for downlink messages.

[0301] In other embodiments, the length of the broadcast status array can be equal to the total number of beams in the cell. Each element in the broadcast status array represents an SI broadcast state, and each SI broadcast state corresponds to a beam. There is a one-to-one correspondence between the beams in the current cell and the SI broadcast states in the broadcast status array, meaning each beam independently corresponds to an SI broadcast state. This improves the flexibility and accuracy of SI broadcast state settings.

[0302] In some further implementations, the length of the broadcast status array may be greater than the total number of beams of the cell, some elements in the broadcast status array are SI broadcast statuses, and some elements are empty, and one SI broadcast status corresponds to one beam.

[0303] In one example, the downlink message includes a SIB1 message, wherein the length of the broadcast status array is determined based on the signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on the signaling overhead” and will not be further described here.

[0304] In another example, the downlink message includes an RRC message, wherein the length of the broadcast status array is determined based on the total number of beams in the current cell. For reference, the length of the power extension array is determined based on the total number of beams in the current cell, and is not further described here.

[0305] S1320: Determine a target position corresponding to the current beam identifier from the broadcast status array based on the pre-acquired current beam identifier.

[0306] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0307] Specifically, there are multiple specific implementation methods for determining the "target position corresponding to the current beam identifier".

[0308] In some embodiments, the target location corresponding to the current beam identifier is determined from the broadcast state array based on a pre-acquired correspondence relationship, where the correspondence relationship is the relationship between the location of the element in the broadcast state array and the beam identifier. This allows the target location corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target location acquisition efficiency.

[0309] In other embodiments, the target position corresponding to the current beam identifier is determined from the broadcast state array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0310] In some examples, the length of the broadcast status array may be smaller than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the broadcast status array. The "remainder + 1" (or "remainder") position in the broadcast status array is then determined as the target position according to the pre-acquired index sequence.

[0311] In other examples, the length of the broadcast status array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the broadcast status array is determined as the target position according to the pre-acquired index order.

[0312] In some other examples, the length of the broadcast status array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the broadcast status array is determined as the target position according to the pre-acquired index order.

[0313] S1330. Obtain the SI broadcast status corresponding to the current beam from the target position.

[0314] Specifically, the SI broadcast state at the target position in the broadcast state array is the SI broadcast state corresponding to the current beam.

[0315] It is understood that the downlink message includes a broadcast status array, so that the SI broadcast status corresponding to the current beam can be directly obtained from the broadcast status array based on the current beam identifier. This makes the acquisition of the SI broadcast status corresponding to the current beam simple and fast, which helps to save computing resources of the terminal device. In addition, the broadcast status array is used to represent the SI broadcast status corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the broadcast status array to re-acquire the SI broadcast status corresponding to the new beam.

[0316] Case 5: SI sending period (i.e. si-Periodicity)

[0317] Information related to SIBs includes the SI transmission periods configured for different beams within a cell and the SI-carrying SIBs. There are various implementations for the specific content of the downlink message and for obtaining the SI transmission period corresponding to the current beam based on the downlink message. A typical example is provided below.

[0318] Method 1

[0319] The downlink message includes a period extension array, and the SI transmission period corresponding to the current beam is obtained from the period extension array. As shown in Figure 14, the method includes:

[0320] S1410. Receive a downlink message sent by a base station, where the downlink message includes: a period extension array, where the period extension array is used to represent the SI transmission period corresponding to each beam in the cell.

[0321] Specifically, the length of the periodic extension array is set according to actual conditions and is not limited thereto.

[0322] In some embodiments, the length of the period extension array can be less than the total number of beams in the cell. Each element in the period extension array represents an SI transmission period, and an SI transmission period corresponds to at least one beam. The period extension array has a smaller data size, which helps reduce the resource usage of the period extension array for downlink messages.

[0323] In other embodiments, the length of the period extension array can be equal to the total number of beams in the cell. Each element in the period extension array represents an SI transmission period, and one SI transmission period corresponds to one beam. There is a one-to-one correspondence between the beams in the current cell and the SI transmission periods in the period extension array, meaning that each beam independently corresponds to an SI transmission period. This improves the flexibility and accuracy of SI transmission period setting.

[0324] In some further implementations, the length of the period extension array may be greater than the total number of beams of the cell, some elements in the period extension array are SI transmission periods, and some elements are empty, and one SI transmission period corresponds to one beam.

[0325] In one example, the downlink message includes a SIB1 message. In some embodiments, the length of the period extension array is determined based on signaling overhead. This can be understood by referring to "The length of the power extension array is determined based on signaling overhead" and will not be further described here.

[0326] In another example, the downlink message includes an RRC message. In some embodiments, the length of the period extension array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power extension array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0327] S1420: Determine a target position corresponding to the current beam identifier from the period extension array based on the pre-acquired current beam identifier.

[0328] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0329] Specifically, there are many specific implementation methods for determining the "target position corresponding to the current beam identifier", which are described below with reference to typical examples, but do not constitute a limitation to the present disclosure.

[0330] In some embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array based on a pre-acquired correspondence relationship, where the pre-acquired correspondence relationship is the correspondence between the positions of elements in the periodic extension array and the beam identifiers. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0331] In other embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0332] In some examples, the length of the periodic extension array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam ID by the length of the periodic extension array. The "remainder + 1" (or "remainder") position in the periodic extension array is then determined as the position corresponding to the current beam ID according to the pre-acquired index sequence.

[0333] In other examples, the length of the periodic extension array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the periodic extension array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0334] In some other examples, the length of the periodic extension array may be greater than the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the periodic extension array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0335] S1430. Obtain the SI transmission period corresponding to the current beam from the target position.

[0336] Specifically, the SI transmission period at the target position in the period extension array is the SI transmission period corresponding to the current beam.

[0337] It is understandable that the downlink message includes a period extension array, so that based on the current beam identifier, the SI transmission period corresponding to the current beam can be directly obtained from the period extension array. This makes the acquisition of the SI transmission period corresponding to the current beam simple and fast, which helps to save computing resources of the terminal device. In addition, the period extension array is used to represent the SI transmission period corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the period extension array to re-acquire the SI transmission period corresponding to the new beam.

[0338] Method 2

[0339] The downlink message may also include a reference SI transmission period and a period multiple corresponding to the current beam. The SI transmission period corresponding to the current beam is obtained based on the reference SI transmission period and the period multiple corresponding to the current beam. As shown in Figure 15, the method includes:

[0340] S1510. Receive a downlink message sent by the base station, wherein the downlink message includes: a reference SI sending period, and a period multiple array, wherein the period multiple array is used to represent the period multiples of the SI sending period corresponding to each beam in the cell relative to the reference SI sending period.

[0341] Specifically, the length of the period multiple array can be set according to actual conditions and is not limited thereto.

[0342] In some embodiments, the length of the period multiples array can be less than the total number of beams in the cell. Each element in the period multiples array represents a period multiple, and each period multiple corresponds to at least one beam. The period multiples array has a smaller data size, which helps reduce the resource usage of the period multiples array for downlink messages.

[0343] In other embodiments, the length of the period multiple array can be equal to the total number of beams in the cell. Each element in the period multiple array represents a period multiple, and each period multiple corresponds to a beam. Beams within the current cell correspond one-to-one to the period multiples in the period multiple array, meaning each beam independently corresponds to a period multiple. This improves the flexibility and accuracy of period multiple setting.

[0344] In some further implementations, the length of the period multiple array may be greater than the total number of beams of the cell, some elements in the period multiple array are period multiples, some elements are empty, and one period multiple corresponds to one beam.

[0345] In one example, the downlink message includes a SIB1 message. In some embodiments, the length of the period multiple array is determined based on signaling overhead. This can be understood by referring to "The length of the power extension array is determined based on signaling overhead" and will not be further described here.

[0346] In another example, the downlink message includes an RRC message. In some embodiments, the length of the period multiple array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power extension array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0347] S1520. Obtain a period multiple corresponding to the current beam from a period multiple array based on a pre-acquired current beam identifier.

[0348] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0349] Specifically, the downlink message is parsed to obtain a reference SI sending period and a period multiple array.

[0350] Specifically, based on the pre-acquired current beam identifier, a target position corresponding to the current beam identifier is determined from a period multiple array; and a period multiple corresponding to the current beam is acquired from the target position.

[0351] Specifically, there are multiple specific implementation methods for determining the "target position corresponding to the current beam identifier".

[0352] In some embodiments, the target position corresponding to the current beam identifier is determined from the period multiples array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the pre-acquired period multiples array and the beam identifier. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0353] In other embodiments, the target position corresponding to the current beam identifier is determined from the period multiple array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0354] In some examples, the length of the period multiples array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam ID by the length of the period multiples array. The "remainder + 1" (or "remainder") position in the period multiples array is then determined as the position corresponding to the current beam ID according to the pre-acquired index sequence.

[0357] Specifically, the period multiple at the target position in the period multiple array is the period multiple corresponding to the current beam.

[0358] S1530. Obtain the SI transmission period corresponding to the current beam according to the reference SI transmission period and the period multiple corresponding to the current beam.

[0359] Specifically, the product of the reference SI transmission period and the period multiple corresponding to the current beam is calculated to obtain the SI transmission period corresponding to the current beam. That is, the SI transmission period corresponding to the current beam = the reference SI transmission period * the period multiple corresponding to the current beam.

[0360] It can be understood that a smaller value for the period multiplier reduces the amount of data in the period multiplier array, which helps reduce the resource usage of the period multiplier array for downlink messages. Furthermore, the period multiplier array is used to represent the period multiplier of the SI transmission period corresponding to each beam within the cell, sent by the base station, relative to the reference SI transmission period. This allows the terminal device to continue to use the period multiplier array to retrieve the period multiplier corresponding to the new beam even if it switches to a new beam.

[0361] Method 3

[0362] The downlink message may also include a reference SI transmission period and a period multiple corresponding to the current beam. The SI transmission period corresponding to the current beam is obtained based on the reference SI transmission period and the period multiple corresponding to the current beam. As shown in Figure 16, the method includes:

[0363] S1610. Receive a downlink message sent by the base station, where the downlink message includes: a reference SI sending period, and a period multiple corresponding to a current beam of the terminal device.

[0364] In some embodiments, the period multiple is configured in the signaling containing the reference SI sending period.

[0365] In other embodiments, the period multiple is configured in the spare bits of the PBCH.

[0366] Exemplarily, the period multiple is configured in the spare 2 bits of the PBCH, but is not limited thereto.

[0367] Specifically, the downlink message is parsed to obtain the reference SI sending period and the period multiple corresponding to the current beam of the terminal device.

[0368] S1620. Obtain the SI transmission period corresponding to the current beam based on the reference SI transmission period and the period multiple corresponding to the current beam.

[0369] Specifically, for understanding S1620, please refer to S1530, which will not be repeated here.

[0370] It is understandable that the downlink message includes the reference SI transmission period and the period multiple corresponding to the current beam, but does not include the period multiples corresponding to other beams, which reduces the resource usage of the downlink message. In addition, the smaller values ​​of the reference SI transmission period and period multiple help further reduce the resource usage of the downlink message.

[0371] Method 4

[0372] The downlink message includes the SI transmission period corresponding to the current beam. The SI transmission period corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 17, the method includes:

[0373] S1710. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: an SI sending period corresponding to the current beam.

[0374] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0375] S1720. Analyze the downlink message to obtain the SI sending period corresponding to the current beam.

[0376] It can be understood that the downlink message includes the SI transmission period corresponding to the current beam, but does not include the SI transmission periods corresponding to other beams, which reduces the resource occupation of the downlink message. In addition, carrying the SI transmission period corresponding to the current beam in the downlink message is similar to carrying the SI transmission period corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the SI transmission period corresponding to the current cell can be replaced with the SI transmission period corresponding to the current beam without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0377] Case 6: SIB to SI mapping relationship (i.e. sib-MappingInfo)

[0378] Information related to SIBs includes the SIB-to-SI mappings for different beams within the cell. There are various implementations for the specific content of the downlink message and for obtaining the SIB-to-SI mapping corresponding to the current beam based on the downlink message. Typical examples are described below.

[0379] Method 1:

[0380] The downlink message includes the mapping relationship between the SIB and SI corresponding to the current beam. The mapping relationship between the SIB and SI corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 18, the method includes:

[0381] S1810. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: a mapping relationship from SIB to SI corresponding to the current beam.

[0382] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0383] S1820. Parse the downlink message to obtain the SIB to SI mapping relationship corresponding to the current beam.

[0384] It can be understood that the downlink message includes the SIB to SI mapping relationship corresponding to the current beam, but does not include the SIB to SI mapping relationship corresponding to other beams, so that the resources occupied by the downlink message are less. In addition, carrying the SIB to SI mapping relationship corresponding to the current beam in the downlink message is similar to carrying the SIB to SI mapping relationship corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the SIB to SI mapping relationship corresponding to the current cell can be replaced with the SIB to SI mapping relationship corresponding to the current beam. There is no need to change the existing protocol, so the improvement workload is small, which helps to reduce the difficulty of the implementation solution.

[0385] Method 2:

[0386] The downlink message includes a mapping relationship array, and the mapping relationship between the SIB and SI corresponding to the current beam is obtained from the mapping relationship array. As shown in Figure 19, the method includes:

[0387] S1910. Receive a downlink message sent by a base station, wherein the downlink message includes: a mapping relationship array, wherein the mapping relationship array is used to represent the mapping relationship from SIB to SI corresponding to each beam in the cell.

[0388] Specifically, the length of the mapping relationship array can be set according to actual conditions and is not limited thereto.

[0389] In some embodiments, the length of the mapping relationship array can be less than the total number of beams in the cell. Each element in the mapping relationship array represents a SIB-to-SI mapping relationship, and each SIB-to-SI mapping relationship corresponds to at least one beam. The mapping relationship array has a small data size, which helps reduce the resource usage of the mapping relationship array for downlink messages.

[0390] In other embodiments, the length of the mapping relationship array may be equal to the total number of beams in the cell, and each element in the mapping relationship array is a SIB-to-SI mapping relationship, and one SIB-to-SI mapping relationship corresponds to one beam. The beams in the current cell correspond one-to-one to the SIB-to-SI mapping relationships in the mapping relationship array, that is, each beam independently corresponds to a SIB-to-SI mapping relationship, which helps to improve the flexibility and accuracy of the SIB-to-SI mapping relationship setting.

[0391] In some other implementations, the length of the mapping relationship array may be greater than the total number of beams of the cell, some elements in the mapping relationship array are SIB to SI mapping relationships, and some elements are empty, and one SIB to SI mapping relationship corresponds to one beam.

[0392] In one example, the downlink message includes: a SIB1 message, wherein the length of the mapping relationship array is determined based on the signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on the signaling overhead” and will not be repeated here.

[0393] In another example, the downlink message includes an RRC message, wherein the length of the mapping relationship array is determined based on the total number of beams in the current cell. For reference, "The length of the power extension array is determined based on the total number of beams in the current cell" is understood and is not further described here.

[0394] S1920: Determine a target position corresponding to the current beam identifier from a mapping relationship array based on the pre-acquired current beam identifier.

[0395] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0396] Specifically, there are multiple specific implementation methods for determining the "target position corresponding to the current beam identifier".

[0397] In some embodiments, the target location corresponding to the current beam identifier is determined from a mapping relationship array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the position of the element in the mapping relationship array and the beam identifier. This allows the target location corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target location acquisition efficiency.

[0398] In other embodiments, the target position corresponding to the current beam identifier is determined from the mapping relationship array according to the pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0399] In some examples, the length of the mapping relationship array may be less than the total number of beams in the cell. In this case, the current beam identifier can be divided by the length of the mapping relationship array to obtain the remainder. Then, according to the pre-acquired index order, the "remainder + 1" (or "remainder") position in the mapping relationship array is determined as the target position.

[0400] In other examples, the length of the mapping relationship array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the mapping relationship array is determined as the target position according to the pre-acquired index order.

[0401] In some other examples, the length of the mapping relationship array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the mapping relationship array is determined as the target position according to the pre-acquired index order.

[0402] S1930. Obtain the SIB to SI mapping relationship corresponding to the current beam from the target position.

[0403] Specifically, the mapping relationship from SIB to SI at the target position in the mapping relationship array is the mapping relationship from SIB to SI corresponding to the current beam.

[0404] It can be understood that the downlink message includes a mapping relationship array, so that the SIB to SI mapping relationship corresponding to the current beam can be directly obtained from the mapping relationship array based on the current beam identifier. In this way, the acquisition method of the SIB to SI mapping relationship corresponding to the current beam can be simple and fast, which is conducive to saving the computing resources of the terminal device. In addition, the mapping relationship array is used to represent the SIB to SI mapping relationship corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the mapping relationship array to re-acquire the SIB to SI mapping relationship corresponding to the new beam.

[0405] Case 7: Resource configuration information of MSG1 used to request non-broadcast SI (i.e. si-RequestConfig)

[0406] Information related to SIBs includes: resource configuration information for MSG1, configured for requesting non-broadcast SI, for different beams within the cell, and the SIBs carried by the SI. There are various implementations for the specific content of the downlink message and for obtaining the resource configuration information for MSG1, corresponding to the current beam, for requesting non-broadcast SI based on the downlink message. The following describes a typical example.

[0407] Method 1:

[0408] The downlink message includes the resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI. The resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI can be obtained by parsing the downlink message. As shown in Figure 20, the method includes:

[0409] S2010. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI.

[0410] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0411] S2020. Parse the downlink message to obtain the resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI.

[0412] It can be understood that the downlink message includes the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam, but does not include the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to other beams, so that the resources occupied by the downlink message are less. In addition, carrying the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam in the downlink message is similar to carrying the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current cell can be replaced with the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam, without changing the existing protocol. Therefore, the improvement workload is small, which is conducive to reducing the difficulty of implementation.

[0413] Method 2

[0414] The downlink message includes a resource array, and the resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI is obtained from the resource array. As shown in Figure 21, the method includes:

[0415] S2110. Receive a downlink message sent by the base station, wherein the downlink message includes: a resource array, wherein the resource array is used to represent resource configuration information of MSG1 corresponding to each beam in the cell for requesting non-broadcast SI.

[0416] Specifically, the length of the resource array can be set according to actual conditions and is not limited thereto.

[0417] In some embodiments, the length of the resource array may be smaller than the total number of beams of the cell, and each element in the resource array is resource configuration information of MSG1 for requesting non-broadcast SI, and resource configuration information of MSG1 for requesting non-broadcast SI corresponds to at least one beam.

[0418] It can be understood that the length of the resource array is smaller than the total number of beams in the cell, which can make the data volume of the resource array smaller, and is conducive to reducing the resource occupation of the resource array for downlink messages.

[0419] In other embodiments, the length of the resource array may be equal to the total number of beams of the cell, and each element in the resource array is resource configuration information of MSG1 for requesting non-broadcast SI, and resource configuration information of MSG1 for requesting non-broadcast SI corresponds to one beam.

[0420] It can be understood that the length of the resource array is equal to the total number of beams in the cell, which can make the beams in the current cell and the resource configuration information of MSG1 in the resource array for requesting non-broadcast SI correspond one to one, that is, each beam independently corresponds to a resource configuration information of MSG1 for requesting non-broadcast SI, which is conducive to improving the flexibility and accuracy of the resource configuration information setting of MSG1 for requesting non-broadcast SI.

[0421] In some further implementations, the length of the resource array may be greater than the total number of beams of the cell, some elements in the resource array are resource configuration information of MSG1 for requesting non-broadcast SI, and some elements are empty, and one resource configuration information of MSG1 for requesting non-broadcast SI corresponds to one beam.

[0422] In one example, the downlink message includes a SIB1 message, wherein the length of the resource array is determined based on the signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on the signaling overhead” and will not be further described here.

[0423] In another example, the downlink message includes an RRC message, wherein the length of the resource array is determined based on the total number of beams in the current cell. For reference, the length of the power extension array is determined based on the total number of beams in the current cell, and is not further described here.

[0424] S2120: Based on the pre-acquired current beam identifier, determine the target position corresponding to the current beam identifier from the resource array.

[0425] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0426] Specifically, there are multiple specific implementation methods for determining the "target position corresponding to the current beam identifier".

[0427] In some embodiments, the target location corresponding to the current beam identifier is determined from the resource array based on a pre-acquired correspondence relationship, where the correspondence relationship is the relationship between the location of the element in the resource array and the beam identifier. This allows the target location corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target location acquisition efficiency.

[0428] In other embodiments, the target position corresponding to the current beam identifier is determined from the resource array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0429] In some examples, the length of the resource array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the resource array. The "remainder + 1" (or "remainder") position in the resource array is then determined as the target position according to the pre-acquired index sequence.

[0430] In other examples, the length of the resource array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the resource array is determined as the target position according to the pre-acquired index order.

[0431] In some other examples, the length of the resource array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the resource array is determined as the target position according to the pre-acquired index order.

[0432] S2130. Obtain resource configuration information of MSG1 corresponding to the current beam for requesting non-broadcast SI from the target location.

[0433] Specifically, the resource configuration information of MSG1 for requesting non-broadcast SI at the target position in the resource array is the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam.

[0434] It can be understood that the downlink message includes a resource array, so that the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam can be directly obtained from the resource array based on the current beam identifier. In this way, the method for obtaining the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the current beam can be simple and fast, which is conducive to saving the computing resources of the terminal device. In addition, the resource array is used to represent the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the resource array to re-acquire the resource configuration information of MSG1 for requesting non-broadcast SI corresponding to the new beam.

[0435] It can be seen that the existing protocol does not support beam-level control of information related to SIBs (including SI broadcast status, SI transmission period, SIB to SI mapping relationship, resource configuration information of MSG1 for requesting non-broadcast SI, etc.). However, in the satellite communication system scenario, the coverage is wide and the number of beams is large. If SIB broadcast services are fixedly provided for each beam in the cell, the time-frequency domain resources will be seriously wasted. The embodiment of the present disclosure supports the configuration of information related to SIBs at the beam level. That is, it supports different SIB transmission situations on different beams according to actual application scenarios and requirements. The saved time-frequency domain resources can be used to provide services for higher priority beams, thereby improving the utilization rate of time-frequency domain resources.

[0436] Case 8: Paging cycle (ie defaultPagingCycle)

[0437] The information related to paging includes: the paging cycles configured for different beams within the cell. At this time, there are many specific implementations of the specific content included in the downlink message and the specific implementation methods of obtaining the paging cycle corresponding to the current beam based on the downlink message. The following is an explanation of a typical example.

[0438] Method 1

[0439] The downlink message includes a cycle extension array, and the paging cycle corresponding to the current beam is obtained from the cycle extension array. As shown in Figure 22, the method includes:

[0440] S2210. Receive a downlink message sent by a base station, wherein the downlink message includes: a period extension array, wherein the period extension array is used to represent a paging period corresponding to each beam in the cell.

[0441] Specifically, the length of the periodic extension array can be set according to actual conditions and is not limited thereto.

[0442] In some embodiments, the length of the period extension array can be less than the total number of beams in the cell. Each element in the period extension array represents a paging cycle, and a paging cycle corresponds to at least one beam. The period extension array has a smaller data size, which helps reduce the resource usage of the period extension array for downlink messages.

[0443] In other embodiments, the length of the cycle extension array can be equal to the total number of beams in the cell. Each element in the cycle extension array represents a paging cycle, and each paging cycle corresponds to a beam. The beams in the current cell correspond one-to-one with the paging cycles in the cycle extension array, meaning each beam independently corresponds to a paging cycle. This improves the flexibility and accuracy of paging cycle configuration.

[0444] In some further implementations, the length of the period extension array may be greater than the total number of beams of the cell, some elements in the period extension array are paging cycles, and some elements are empty, and one paging cycle corresponds to one beam.

[0445] In one example, the downlink message includes a SIB1 message, wherein the length of the period extension array is determined based on signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on signaling overhead” and will not be further described here.

[0446] In another example, the downlink message includes an RRC message, wherein the length of the period extension array is determined based on the total number of beams in the current cell. For reference, the length of the power extension array is determined based on the total number of beams in the current cell, and is not further described here.

[0447] S2220. Determine a target position corresponding to the current beam identifier from the periodic extension array based on the pre-acquired current beam identifier.

[0448] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0449] Specifically, there are many specific implementation methods for determining the "target position corresponding to the current beam identifier", which are described below with reference to typical examples, but do not constitute a limitation to the present disclosure.

[0450] In some embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the periodic extension array and the beam identifiers. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0451] In other embodiments, the target position corresponding to the current beam identifier is determined from the periodic extension array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0452] In some examples, the length of the periodic extension array may be smaller than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the periodic extension array. The "remainder + 1" (or "remainder") position in the periodic extension array is then determined as the target position according to the pre-acquired index sequence.

[0453] In other examples, the length of the periodic extension array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the periodic extension array is determined as the target position according to the pre-acquired index order.

[0454] In some other examples, the length of the periodic extension array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the periodic extension array is determined as the target position according to the pre-acquired index order.

[0455] S2230. Obtain the paging cycle corresponding to the current beam from the target position.

[0456] Specifically, the paging cycle at the target position in the cycle extension array is the paging cycle corresponding to the current beam.

[0457] It is understood that the downlink message includes a cycle extension array, allowing the paging cycle corresponding to the current beam to be directly obtained from the cycle extension array based on the current beam identifier. This simplifies and expedits the acquisition of the paging cycle corresponding to the current beam, thereby conserving computing resources on the terminal device. Furthermore, the cycle extension array is used to represent the paging cycles corresponding to each beam within the cell, so that even if the terminal device switches to a new beam, it can continue to use the cycle extension array to re-acquire the paging cycle corresponding to the new beam.

[0458] Method 2

[0459] The downlink message includes a reference paging cycle and a cycle multiple array, and the cycle multiple corresponding to the current beam is obtained from the cycle multiple array. Then, based on the reference paging cycle and the cycle multiple corresponding to the current beam, the paging cycle corresponding to the current beam is obtained. As shown in Figure 23, the method includes:

[0460] S2310. Receive a downlink message sent by the base station, wherein the downlink message includes: a reference paging cycle, and a cycle multiple array, wherein the cycle multiple array is used to represent the cycle multiples of the paging cycle corresponding to each beam in the cell relative to the reference paging cycle.

[0461] Specifically, the length of the period multiple array is set according to actual conditions and is not limited thereto.

[0462] In some embodiments, the length of the period multiples array can be less than the total number of beams in the cell. Each element in the period multiples array represents a period multiple, and each period multiple corresponds to at least one beam. The period multiples array has a smaller data size, which helps reduce the resource usage of the period multiples array for downlink messages.

[0463] In other embodiments, the length of the period multiple array can be equal to the total number of beams in the cell. Each element in the period multiple array represents a period multiple, and each period multiple corresponds to a beam. Beams within the current cell correspond one-to-one to the period multiples in the period multiple array, meaning each beam independently corresponds to a period multiple. This improves the flexibility and accuracy of period multiple setting.

[0464] In some further implementations, the length of the period multiple array may be greater than the total number of beams of the cell, some elements in the period multiple array are period multiples, some elements are empty, and one period multiple corresponds to one beam.

[0465] In one example, the downlink message includes a SIB1 message. In some embodiments, the length of the period multiple array is determined based on signaling overhead. This can be understood by referring to "The length of the power extension array is determined based on signaling overhead" and will not be further described here.

[0466] In another example, the downlink message includes an RRC message. In some embodiments, the length of the period multiple array is determined based on the total number of beams in the current cell. This can be understood by referring to "The length of the power extension array is determined based on the total number of beams in the current cell" and will not be further explained here.

[0467] S2320. Obtain the period multiple corresponding to the current beam from the period multiple array based on the pre-acquired current beam identifier.

[0468] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0469] Specifically, the downlink message is parsed to obtain a reference paging cycle and a cycle multiple array.

[0470] Specifically, based on the pre-acquired current beam identifier, a target position corresponding to the current beam identifier is determined from a period multiple array; and a period multiple corresponding to the current beam is acquired from the target position.

[0471] Specifically, there are multiple specific implementation methods for determining the "target position corresponding to the current beam identifier".

[0472] In some embodiments, the target position corresponding to the current beam identifier is determined from the period multiples array based on a pre-acquired correspondence relationship, where the correspondence relationship is the correspondence between the positions of elements in the pre-acquired period multiples array and the beam identifier. This allows the target position corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target position acquisition efficiency.

[0473] In other embodiments, the target position corresponding to the current beam identifier is determined from the period multiple array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0474] In some examples, the length of the period multiples array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam ID by the length of the period multiples array. The "remainder + 1" (or "remainder") position in the period multiples array is then determined as the position corresponding to the current beam ID according to the pre-acquired index sequence.

[0475] In other examples, the length of the period multiples array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the period multiples array is determined as the position corresponding to the current beam identifier according to the pre-acquired index order.

[0476] In yet other examples, the length of the period multiples array may be greater than the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the period multiples array is determined as the position corresponding to the current beam identifier according to the pre-acquired index sequence.

[0477] Specifically, the period multiple at the target position in the period multiple array is the period multiple corresponding to the current beam.

[0478] S2330. Obtain the paging cycle corresponding to the current beam according to the reference paging cycle and the cycle multiple corresponding to the current beam.

[0479] Specifically, the product of the reference paging cycle and the cycle multiple corresponding to the current beam is calculated to obtain the paging cycle corresponding to the current beam, that is, the paging cycle corresponding to the current beam = reference paging cycle * cycle multiple corresponding to the current beam.

[0480] It is understandable that a smaller value for the cycle multiplier reduces the amount of data in the cycle multiplier array, which helps reduce the resource usage of the cycle multiplier array for downlink messages. Furthermore, the cycle multiplier array is used to represent the cycle multipliers of the paging cycles corresponding to each beam within the cell, sent by the base station, relative to the reference paging cycle. This allows the terminal device to continue to use the cycle multiplier array to reacquire the cycle multiplier corresponding to the new beam even if it switches to a new beam.

[0481] Method 3

[0482] The downlink message may also include a reference paging cycle and a cycle multiple corresponding to the current beam. The paging cycle corresponding to the current beam is obtained based on the reference paging cycle and the cycle multiple corresponding to the current beam. As shown in Figure 24, the method includes:

[0483] S2410. Receive a downlink message sent by the base station, where the downlink message includes: a reference paging cycle, and a cycle multiple corresponding to a current beam of the terminal device.

[0484] In some embodiments, the cycle multiple is configured in the signaling of the reference paging cycle.

[0485] In other embodiments, the period multiple is configured in the spare bits of the PBCH.

[0486] Exemplarily, the period multiple is configured in the spare 2 bits of the PBCH, but is not limited thereto.

[0487] Specifically, the downlink message is parsed to obtain a reference paging cycle and a cycle multiple corresponding to the current beam of the terminal device.

[0488] S2420. Obtain the paging cycle corresponding to the current beam according to the reference paging cycle and the cycle multiple corresponding to the current beam.

[0489] Specifically, the understanding of S2420 can refer to S2330, which will not be repeated here.

[0490] It is understood that the downlink message includes the reference paging cycle and the cycle multiple corresponding to the current beam, but does not include the cycle multiples corresponding to other beams, which reduces the resource usage of the downlink message. In addition, the smaller values ​​of the reference paging cycle and cycle multiple help further reduce the resource usage of the downlink message.

[0491] Method 4

[0492] The downlink message includes the paging cycle corresponding to the current beam. The paging cycle corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 25, the method includes:

[0493] S2510. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: a paging cycle corresponding to the current beam.

[0494] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0495] S2520. Analyze the downlink message to obtain the paging cycle corresponding to the current beam.

[0496] It can be understood that the downlink message includes the paging cycle corresponding to the current beam, but does not include the paging cycles corresponding to other beams, which reduces the resource usage of the downlink message. Furthermore, carrying the paging cycle corresponding to the current beam in the downlink message is similar to carrying the paging cycle corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the paging cycle corresponding to the current cell can be replaced with the paging cycle corresponding to the current beam, without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0497] Case 9: Paging timing and paging location information (i.e., nAndPagingFrameOffset)

[0498] The information related to paging includes: the paging timing and paging location information corresponding to different beams in the cell. At this time, there are many specific implementation methods for the specific content included in the downlink message and for obtaining the paging timing and paging location information corresponding to the current beam based on the downlink message.

[0499] The downlink message includes the paging opportunity and paging location information corresponding to the current beam. The paging opportunity and paging location information corresponding to the current beam can be obtained by parsing the downlink message. As shown in Figure 26, the method includes:

[0500] S2610. Receive a downlink message sent by the base station for the current beam of the terminal device, wherein the downlink message includes: paging timing and paging location information corresponding to the current beam.

[0501] In some embodiments, the downlink message includes: a SIB1 message, or an RRC message.

[0502] S2620. Analyze the downlink message to obtain the paging timing and paging location information corresponding to the current beam.

[0503] It can be understood that the downlink message includes the paging opportunity and paging location information corresponding to the current beam, but does not include the paging opportunity and paging location information corresponding to other beams, which reduces the resource usage of the downlink message. In addition, carrying the paging opportunity and paging location information corresponding to the current beam in the downlink message is similar to carrying the paging opportunity and paging location information corresponding to the current cell in the downlink message in the related art. Therefore, based on the related art, the paging opportunity and paging location information corresponding to the current cell can be replaced with the paging opportunity and paging location information corresponding to the current beam without changing the existing protocol. Therefore, the improvement workload is relatively small, which helps to reduce the difficulty of implementation.

[0504] Method 2

[0505] The downlink message includes a paging information array, and the paging opportunity and paging location information corresponding to the current beam are obtained from the paging information array. As shown in Figure 27, the method includes:

[0506] S2710. Receive a downlink message sent by a base station, wherein the downlink message includes: a paging information array, wherein the paging information array is used to indicate paging timing and paging location information corresponding to each beam in the cell.

[0507] Specifically, the length of the paging information array can be set according to actual conditions and is not limited thereto.

[0508] In some embodiments, the length of the paging information array can be less than the total number of beams in the cell. Each element in the paging information array represents a paging opportunity and paging location information, and each paging opportunity and paging location information corresponds to at least one beam. The paging information array has a small data size, which helps reduce the resource usage of the paging information array for downlink messages.

[0509] In other embodiments, the length of the paging information array can be equal to the total number of beams in the cell. Each element in the paging information array represents a paging opportunity and paging location information, and each paging opportunity and paging location information corresponds to a beam. There is a one-to-one correspondence between the beams in the current cell and the paging opportunities and paging location information in the paging information array. That is, each beam independently corresponds to a paging opportunity and paging location information, which facilitates increased flexibility and accuracy in setting paging opportunities and paging location information.

[0510] In some further implementations, the length of the paging information array may be greater than the total number of beams of the cell, some elements in the paging information array are paging occasions and paging location information, and some elements are empty, and one paging occasion and paging location information corresponds to one beam.

[0511] In one example, the downlink message includes a SIB1 message, wherein the length of the paging information array is determined based on the signaling overhead. This can be understood by referring to “the length of the power extension array is determined based on the signaling overhead” and will not be further described here.

[0512] In another example, the downlink message includes an RRC message, wherein the length of the paging information array is determined based on the total number of beams in the current cell. For reference, the length of the power extension array is determined based on the total number of beams in the current cell, and is not further described here.

[0514] Specifically, for the understanding of the current beam identifier, please refer to the previous text and will not be repeated here.

[0515] Specifically, there are many specific implementation methods for determining the "target position corresponding to the current beam identifier", which are described below with reference to typical examples, but do not constitute a limitation to the present disclosure.

[0516] In some embodiments, the target location corresponding to the current beam identifier is determined from the paging information array based on a pre-acquired correspondence relationship, where the correspondence relationship is the relationship between the position of the element in the paging information array and the beam identifier. This allows the target location corresponding to the current beam identifier to be quickly acquired by querying the correspondence relationship, improving target location acquisition efficiency.

[0517] In other embodiments, the target position corresponding to the current beam identifier is determined from the paging information array according to a pre-acquired index sequence. In this way, the target position corresponding to the current beam identifier can be quickly acquired according to the pre-acquired index sequence, thereby improving the efficiency of acquiring the target position.

[0518] In some examples, the length of the paging information array may be less than the total number of beams in the cell. In this case, the remainder is obtained by dividing the current beam identifier by the length of the paging information array. The "remainder + 1" (or "remainder") position in the paging information array is then determined as the target position according to the pre-acquired index sequence.

[0519] In other examples, the length of the paging information array may be equal to the total number of beams in the cell. In this case, the "current beam identifier + 1" (or "current beam identifier") position in the paging information array is determined as the target position according to the pre-acquired index order.

[0520] In some other examples, the length of the paging information array may be greater than the total number of beams in the cell. In this case, the "current beam identifier" (or "current beam identifier") position in the paging information array is determined as the target position according to the pre-acquired index order.

[0521] S2730. Obtain the paging timing and paging location information corresponding to the current beam from the target location.

[0522] Specifically, the paging opportunity and paging position information at the target position in the paging information array are the paging opportunity and paging position information corresponding to the current beam.

[0523] It is understood that the downlink message includes a paging information array, so that based on the current beam identifier, the paging opportunity and paging location information corresponding to the current beam can be directly obtained from the paging information array. This makes the acquisition of the paging opportunity and paging location information corresponding to the current beam simple and fast, which helps to save computing resources of the terminal device. In addition, the paging information array is used to represent the paging opportunity and paging location information corresponding to each beam in the cell, so that even if the terminal device switches to a new beam, it can continue to use the paging information array to re-acquire the paging opportunity and paging location information corresponding to the new beam.

[0524] It can be seen that when a terminal device moves from one cell to another, the system information will change, and the network needs to notify the terminal device through paging to receive system information update messages. This application scenario will only occur in the beam at the edge of the cell. However, the existing protocol notifies the paging configuration at the cell level, that is, it is assumed that the paging configuration of all beams in the cell is the same, which will obviously cause unnecessary waste of resources. The disclosed embodiment supports beam-level paging configuration (paging cycle, paging timing, and paging location information, etc.), that is, the paging configurations on different beams in the cell can be different. In this way, longer paging cycles and sparser paging timings can be provided for some beams, and shorter paging cycles and denser paging timings can be provided for other beams. For example, shorter paging cycles and denser paging timings are provided for beams at the edge of the cell, so that they can receive new system information in a timely manner. In this way, the problem of resource waste in the existing protocol can be improved.

[0525] The present disclosure also provides an information processing method for a base station. For example, Figure 28 is a flowchart illustrating an information processing method provided by an embodiment of the present disclosure. This method can be performed by an information processing device, which can be implemented using software and / or hardware and is generally integrated into a base station. Depending on the specific application scenario, a base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices over the air interface through one or more sectors, or can be called something else.

[0532] S2820. Send a downlink message including configuration information to the terminal device, where the downlink message is used to instruct the terminal device to obtain information corresponding to the configuration of the current beam.

[0533] For the understanding of S2810 and S2820, please refer to the previous article and will not be repeated here.

[0534] In the embodiment of the present disclosure, the information corresponding to the beam configuration is configured at the beam level, that is, different beams within the same cell can be configured with different information, which makes the configuration of the information corresponding to the beam configuration more flexible, and is conducive to matching the information corresponding to the beam configuration with the actual communication scenarios and needs corresponding to the beam, thereby improving communication performance and enhancing user experience.

The SSB transmit power corresponding to the current beam = the reference SSB transmit power / the attenuation value in dB corresponding to the current beam.
