[0112] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0113] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0114] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0115] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0116] In some embodiments, when the terminal switches cells, after switching from the source cell (for example, the cell before the switch) to the first cell (for example, it can also be called the target cell), it is generally necessary to initiate random access in the first cell. For example, a random access preamble sequence (RACH preamble) can be sent to the first cell to obtain uplink synchronization, and then a PUSCH (Physical Uplink Shared Channel) can be sent to the first cell.

[0117] In some embodiments, the terminal can implement cell switching based on RACH-less (RACH-less, where RACH stands for Random Access Channel, which can be referred to as random access) switching. That is, after switching from the source cell to the first cell, the terminal does not need to initiate a random access process in the first cell, that is, it does not send a RACH preamble in the first cell, but can directly send a PUSCH and a radio resource control reconfiguration completion RRCReconfigurationcomplete (RRC stands for Radio Resource Control) message based on the uplink grant (UL grant) sent by the first cell.

[0118] For example, when the terminal is in a non-terrestrial network (NTN), the satellite corresponding to the cell where the terminal is located is moving at high speed in the air. Since the satellite's signal coverage range is large, the range of the corresponding cell is also large, so there are more terminals in the cell. When the satellite moves away from the terminal in the cell, the terminals in the cell need to switch cells, resulting in a large number of terminals switching to the first cell almost at the same time. If a large number of terminals initiate random access in the first cell, due to limited RACH resources, random access congestion will occur, and random access failure of many terminals will fail, which may also cause terminal handover failure. Therefore, for terminals in the NTN, it is possible to switch from the source cell to the first cell based on random access-free handover. Since there is no need to initiate random access, there will be no congestion caused by a large number of terminals initiating random access at the same time, thereby avoiding random access failure and further avoiding handover failure.

[0119] However, cell handover based on non-random access handover can present technical challenges in certain scenarios. For example, when a terminal is in a New Radio (NR) network, such as NR NTN or NR TN (Terrestrial Network), beam pairing is required between the terminal and the NR network equipment because the NR is a multi-beam system.

[0120] In some embodiments, the network device of the first cell may send SSBs (Synchronization Signal and PBCH blocks, also referred to as synchronization signal blocks, where PBCH stands for Physical Broadcast Channel) in multiple directions. For example, in an SS Burst Set, the network device may send different SSBs in different directions. The SSBs are associated with beams.

[0121] By receiving the SSB, the terminal can determine the Synchronization Signal Reference Signal Received Power (SS-RSRP) of the synchronization signal. The terminal can determine the appropriate SSB based on the SS-RSRP corresponding to each SSB, and then determine that the beam associated with the SSB is the appropriate transmitting beam of the first cell.

[0122] Furthermore, the terminal may initiate random access in the first cell. The synchronization signal block index (SSB index) is associated with relevant information of the random access, for example, the SSB index is associated with a random access opportunity (RACH occasion), for example, the SSB index is associated with a preamble. Therefore, the terminal may initiate random access based on the random access information associated with the determined SSB, for example, on a RACH occasion associated with the SSB index, send a preamble associated with the SSB index to the network device of the first cell.

[0123] The network device can determine the SSB that the terminal considers appropriate based on the SSB associated with the random access information, and further determine the transmit beam of the first cell that the terminal considers appropriate, so that the first cell can communicate with the terminal using the beam as the transmit beam. In this way, beam pairing is achieved.

[0124] It can be seen that the beam pairing process needs to be implemented based on random access. However, when the terminal switches to the first cell based on non-random access switching, it is not necessary to initiate random access in the first cell, which makes the above-mentioned beam pairing process impossible to implement, and it is difficult to ensure the communication quality of the terminal in the first cell.

[0125] FIG1B is an interactive diagram illustrating a method for transmitting beam information according to an embodiment of the present disclosure. The beam transmitting method can be applied to a communication system.

[0126] As shown in FIG1B , the beam information sending method includes:

[0127] Step S101: The terminal sends first information to a network device of a first cell.

[0128] In one embodiment, the network device includes at least one of the following: an access network device and a core network device.

[0133] In some embodiments, the information of at least one transmitting beam of the first cell sent by the terminal to the network device of the first cell may include third information, where the third information is associated with the reference signal receiving power of the synchronization signal, and the reference signal receiving power of the synchronization signal is greater than or equal to the first threshold.

[0134] In some embodiments, when the at least one beam includes multiple beams, the terminal may further send priority information of each beam to the network device of the first cell.

[0135] Step S102: The network device of the source cell may indicate fourth information to the terminal.

[0136] In some embodiments, the fourth information is used to indicate information of the transmission beam of the first cell.

[0137] In some embodiments, the terminal sends the first information to the first cell only when at least one transmission beam of the determined first cell is different from the transmission beam of the first cell indicated by the source cell; and when at least one transmission beam of the determined first cell is the same as the transmission beam of the first cell indicated by the source cell, it is not necessary to send the first information to the first cell.

[0138] In step S103 , the terminal may determine the transmit beam of the first cell.

[0139] In some embodiments, the terminal may determine the transmit beam of the first cell based on the downlink transmission of the first cell.

[0140] In some embodiments, the terminal sends the first information to the first cell only when at least one transmission beam of the determined first cell is different from the transmission beam of the first cell indicated by the source cell; and when at least one transmission beam of the determined first cell is the same as the transmission beam of the first cell indicated by the source cell, it is not necessary to send the first information to the first cell.

[0141] The communication method involved in the embodiments of the present disclosure may include at least one of steps S101 to S103. For example, step S101 can be implemented as an independent embodiment, step S102 can be implemented as an independent embodiment, step S103 can be implemented as an independent embodiment, step S101+step S102+step S103 can be implemented as an independent embodiment, step S101+step S102 can be implemented as an independent embodiment, step S101+step S103 can be implemented as an independent embodiment, and step S102+step S103 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0146] For the relevant embodiments of the terminal and the network device in FIG1B , please refer to the embodiments below, which will not be described in detail in this disclosure.

[0147] First, embodiments of the present disclosure provide a method for transmitting beam information. Figure 2 is a schematic flowchart illustrating a method for transmitting beam information according to an embodiment of the present disclosure. The beam information transmission method illustrated in this embodiment can be executed by a terminal, which can communicate with a network device. Specific examples of the terminal and network device can be found in Figure 1A and are not further described here.

[0148] As shown in FIG2 , the beam information sending method may include the following steps:

[0149] In step S201, first information is sent to a first cell, where the first information is information of at least one transmit beam of the first cell determined by the terminal, and the first cell is a cell to which the terminal switches based on non-random access switching.

[0150] It should be noted that sending information to the first cell specifically refers to sending information to the network device of the first cell, which is generally referred to as sending information to the first cell in the art.

[0151] According to an embodiment of the present disclosure, when a terminal is handed over to a first cell based on a no-access-at-anytime handover, the terminal may send first information to the first cell, where the first information is information about at least one transmit beam of the first cell determined by the terminal. This ensures that a network device in the first cell can learn information about a transmit beam of the first cell deemed appropriate by the terminal, so that the network device can use the beam as a transmit beam in the first cell to communicate with the terminal, thereby ensuring communication quality for the terminal in the first cell.

[0152] In some embodiments, the first cell may be an NR cell, or a cell of other radio access technology (RAT), such as an LTE (Long Term Evolution) cell. For example, when the first cell is an NR cell, the first cell may specifically be an NR NTN cell, or an NR TN cell.

[0153] In some embodiments, the information of at least one transmitting beam of the first cell determined by the terminal can play an auxiliary role for the network device. After the network device learns the information of the transmitting beam of the first cell that the terminal considers suitable, it can use the beam as the transmitting beam in the first cell to communicate with the terminal, or it can select other beams as the transmitting beam in the first cell to communicate with the terminal, depending on the implementation of the network device.

[0154] In some embodiments, the first information is carried in a radio resource control (RRC) message. For example, the terminal may send the first information to a network device of the first cell via an RRC message carrying the first information, wherein existing bits in the RRC message may be reused to carry the first information, or bits in the RRC message may be expanded to carry the first information.

[0155] In some embodiments, the radio resource control signaling includes: a radio resource control reconfiguration complete (RRCReconfigurationcomplete) message.

[0156] In some embodiments, the transmit beam of the first cell determined by the terminal includes at least one of the following:

[0157] The transmit beam of the first cell requested by the terminal;

[0158] The transmit beam of the first cell recommended by the terminal;

[0159] The transmitting beam of the first cell selected by the terminal.

[0160] In some embodiments, the information of the at least one transmit beam of the first cell includes at least one of the following:

[0161] second information, wherein the second information is associated with a reference signal received power of the synchronization signal, and the reference signal received power of the synchronization signal is greater than or equal to a first threshold;

[0162] The third information is associated with a reference signal received power of a channel state information reference signal, and the reference signal received power of the channel state information reference signal (Channel-State-Information Reference Signal, CSI RS) is greater than or equal to a second threshold.

[0163] In some embodiments, after switching to the first cell, the terminal may receive an SSB transmitted by the first cell on at least one beam, and determine the power of the received SSB as the SS-RSRP, and further determine an SS-RSRP greater than or equal to a first threshold from the at least one SS-RSRP, and transmit second information associated with the SSB corresponding to the determined SS-RSRP as information of the transmission beam to the first cell. The network device of the first cell may determine the received second information, and further determine that the beam corresponding to the SSB is a transmission beam of the first cell deemed appropriate by the terminal.

[0164] For example, the second information includes at least one of the following: an index of a synchronization signal block (SSB index); and a reference signal received power (SS-RSRP) of a synchronization signal corresponding to the synchronization signal block.

[0165] In some embodiments, after switching to the first cell, the terminal may receive the CSI RS sent by the first cell on at least one beam, and determine the power of the received CSI RS as the CSI RS-RSRP, and then determine a CSI RS-RSRP greater than or equal to a first threshold in the at least one CSI RS-RSRP, and send the third information associated with the CSI RS corresponding to the determined CSI RS-RSRP as information of the transmit beam to the first cell. The network device of the first cell may determine the received third information, and then determine that the beam corresponding to the CSI RS is the transmit beam of the first cell that the terminal considers appropriate.

[0166] For example, the third information includes at least one of the following: an index of a channel state information reference signal (CSI RS index); a reference signal received power of a channel state information reference signal (CSI RS-RSRP); an index of a synchronization signal block (SSB index), wherein the index of the synchronization signal block is associated with the channel state information reference signal; a reference signal received power of a synchronization signal of a synchronization signal block (SS-RSRP), wherein the synchronization signal block is associated with the channel state information reference signal.

[0167] FIG3 is a schematic flow chart of another method for transmitting beam information according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by a terminal. As shown in FIG3 , the beam transmission method further includes:

[0168] In step S301, priority information of each beam in at least one beam is sent to a first cell, where the at least one beam includes multiple beams.

[0169] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure, and the present disclosure does not limit the specific implementation manner.

[0170] In some embodiments, the first information sent by the terminal to the first cell may include information about multiple transmission beams of the first cell, that is, at least one beam includes multiple beams. In this case, the terminal may send priority information for each of the multiple beams to the first cell. The priority information may be sent to the first cell together with the first information or may be sent to the first cell separately. For example, the priority information may be sent to the first cell before or after the first information is sent.

[0171] By sending the priority information for each beam to the first cell, the network equipment in the first cell can prioritize the multiple beams deemed suitable by the terminal. The suitability is ranked from high to low, with the beam with the highest priority being the beam deemed most suitable by the terminal. This facilitates the network equipment in the first cell to select a beam with a relatively high priority as the transmission beam for communication with the terminal in the first cell, thereby ensuring good communication quality for the terminal.

[0172] For example, the network device of the first cell can first determine whether the beam with the highest priority can be used to communicate with the terminal. When it is determined that the beam with the highest priority can be used to communicate with the terminal, the beam with the highest priority can be used as the transmission beam to communicate with the terminal in the first cell; and if it is determined that the beam with the highest priority cannot be used to communicate with the terminal, it can be further determined whether the beam with the second highest priority can be used to communicate with the terminal. When it is determined that the beam with the second highest priority can be used to communicate with the terminal, the beam with the second highest priority can be used as the transmission beam to communicate with the terminal in the first cell; and if it is determined that the beam with the second highest priority cannot be used to communicate with the terminal, it can be further determined whether the beam with the third highest priority can be used to communicate with the terminal. By analogy, the network device gives priority to selecting a beam with a relatively high priority that can be used to communicate with the terminal as the transmission beam of the first cell to communicate with the terminal.

[0173] FIG4 is a schematic flow chart of another method for transmitting beam information according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by a terminal. As shown in FIG4 , the method for transmitting beam information further includes:

[0174] In step S401, fourth information indicated by a source cell is received, where the fourth information is used to indicate information of a transmitting beam of the first cell.

[0175] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure, and the present disclosure does not limit the specific implementation method.

[0176] In some embodiments, the source cell may indicate fourth information to the terminal, and the fourth information may indicate information about the transmit beam of the first cell. Based on the fourth information, the terminal may determine information about the transmit beam of the first cell, and further determine the transmit beam used by the first cell.

[0177] In some embodiments, the information of the transmitted beam is carried in at least one of the following: a conditional switching configuration; a switching command.

[0178] For example, the terminal cell switching is conditional handover (CHO), and the network device can send a conditional handover configuration to the terminal (for example, in the source cell). Then, the conditional handover configuration can carry the information of the transmitting beam of the first cell, and the terminal can determine the information of the transmitting beam of the first cell in the conditional handover configuration.

[0179] For example, the terminal cell switching is not a conditional switching. The network device can (for example, in the source cell) send a switching command to the terminal. Then the switching command can carry the information of the transmitting beam of the first cell, and the terminal can determine the information of the transmitting beam of the first cell in the switching command.

[0180] In some embodiments, the conditional handover configuration may be carried in an RRC reconfiguration message. In some embodiments, the handover command may be carried in an RRC reconfiguration message.

[0181] In some embodiments, sending the first information to the first cell includes at least one of the following:

[0182] At least one transmit beam of the first cell determined by the terminal is different from the transmit beam of the first cell indicated by the source cell, and the terminal sends first information to the first cell;

[0183] At least one transmission beam of the first cell determined by the terminal is the same as the transmission beam of the first cell indicated by the source cell, and the first information is not sent to the first cell.

[0184] In some embodiments, the terminal may determine at least one transmit beam of the first cell and, based on fourth information indicated by the source cell, determine the transmit beam used by the first cell as indicated by the source cell. Furthermore, the terminal may determine whether the at least one transmit beam of the first cell determined by the terminal is the same as the transmit beam of the first cell indicated by the source cell.

[0185] When at least one transmitting beam of the first cell determined by the terminal is different from the transmitting beam of the first cell indicated by the source cell, the transmitting beam used by the first cell is not the beam considered appropriate by the terminal. Therefore, first information can be sent to the first cell so that the network device can use the beam considered appropriate by the terminal as the transmitting beam to communicate with the terminal in the first cell, so as to ensure the communication quality of the terminal in the first cell.

[0186] If at least one transmit beam of the first cell determined by the terminal is the same as the transmit beam of the first cell indicated by the source cell, the transmit beam used by the first cell is deemed appropriate by the terminal. After handing over to the first cell, the terminal can communicate in the first cell based on the beam deemed appropriate by the terminal, thereby ensuring good communication quality. Therefore, it is not necessary to send the first information to the first cell, which helps save communication resources.

[0187] FIG5 is a schematic flow chart of another method for transmitting beam information according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by a terminal. As shown in FIG4 , the method for transmitting beam information further includes:

[0188] In step S501, a transmit beam of the first cell is determined according to downlink transmission of the first cell.

[0189] In some embodiments, a terminal may receive a downlink transmission from a first cell and determine a transmit beam for the first cell based on the downlink transmission from the first cell. For example, the terminal may receive a downlink transmission sent by each beam in the first cell and parse the received downlink transmissions. Upon successfully parsing a downlink transmission, the terminal may determine that the beam containing the downlink transmission is the transmit beam of the first cell.

[0190] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure, and the present disclosure does not limit the specific implementation method.

[0191] The downlink transmission includes at least one of the following: physical layer information, radio access control layer messages, and media access control layer messages. The following embodiments are mainly described as examples when the downlink transmission includes physical layer information, for example, the physical layer information includes a physical downlink control channel (PDCCH).

[0192] For example, the terminal is pre-configured with a Cell-Radio Network Temporary Identifier (C-RNTI) for parsing the Physical Downlink Control Channel (PDCCH) sent by the first cell. After switching to the first cell, the terminal can receive the PDCCH sent by the first cell in each beam and attempt to parse the PDCCH using the C-RNTI. If a PDCCH is successfully parsed, the terminal can communicate with the first cell in the beam where the PDCCH is located, thereby determining that the beam where the PDCCH is located is the transmit beam of the first cell.

[0193] In the case where a UL grant is carried in the downlink transmission, the terminal may send a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), an RRCReconfigurationcomplete message, etc. according to the UL grant.

[0194] In this embodiment, before receiving the downlink transmission of the first cell, the terminal can determine the resources and / or sending rules of the downlink transmission of the first cell, so that after switching to the first cell, the terminal can smoothly receive the downlink transmission of the first cell using the resources and / or sending rules of the downlink transmission.

[0195] In some embodiments, when determining the transmit beam for the first cell based on the downlink transmission of the first cell, the terminal may also consider the signal quality of the beam. For example, when a downlink transmission is received on a certain beam, the terminal may determine whether the signal quality of the downlink transmission meets the requirements, where the signal quality meets at least one of the following requirements: the SS-RSRP of the SSB corresponding to the beam containing the downlink transmission is greater than or equal to a first threshold, and the CSI RS-RSRP of the CSI RS corresponding to the beam containing the downlink transmission is greater than or equal to a second threshold.

[0196] Only when the signal quality of the downlink transmission meets the requirements will further attempts be made to parse the downlink transmission. Accordingly, it can be ensured that the transmit beam determined by the terminal based on the downlink transmission of the first cell is not only the beam used for communication between the terminal and the first cell, but also a beam with communication quality that meets the requirements.

[0197] In some embodiments, sending the first information to the first cell includes at least one of the following:

[0198] At least one transmit beam of the first cell determined by the terminal is different from the transmit beam of the first downlink cell determined through downlink transmission, and the terminal sends first information to the first cell;

[0199] At least one transmit beam of the first cell determined by the terminal is the same as the transmit beam of the first downlink cell determined through downlink transmission, and the first information is not sent to the first cell.

[0200] In some embodiments, the terminal may determine at least one transmit beam of the first cell and determine the transmit beam of the first cell based on downlink transmission of the first cell. Furthermore, the terminal may determine whether the at least one transmit beam of the first cell determined by the terminal is the same as the transmit beam of the first cell determined based on downlink transmission of the first cell.

[0201] When at least one transmitting beam of the first cell determined by the terminal is different from the transmitting beam of the first cell determined based on the downlink transmission of the first cell, the transmitting beam used by the first cell is not the beam considered appropriate by the terminal. Therefore, first information can be sent to the first cell so that the network device can use the beam considered appropriate by the terminal as the transmitting beam to communicate with the terminal in the first cell, so as to ensure the communication quality of the terminal in the first cell.

[0202] If at least one transmit beam of the first cell determined by the terminal is the same as the transmit beam of the first cell determined based on downlink transmission of the first cell, then the transmit beam used by the first cell is the beam deemed appropriate by the terminal. After handing over to the first cell, the terminal can communicate in the first cell based on the beam deemed appropriate by the terminal, thereby ensuring good communication quality. Therefore, it is not necessary to send the first information to the first cell, which helps save communication resources.

[0209] Secondly, embodiments of the present disclosure provide a method for receiving beam information. Figure 6 is a schematic flowchart illustrating a method for receiving beam information according to an embodiment of the present disclosure. The beam information receiving method illustrated in this embodiment can be executed by a network device, which can communicate with a terminal. Specific examples of the terminal and network device can be found in Figure 1A and are not further described here.

[0210] As shown in FIG6 , the beam information receiving method may include the following steps:

[0211] In step S601, first information sent by a terminal is received, where the first information is information of at least one transmit beam of a first cell determined by the terminal, the first cell is a cell to which the terminal switches based on non-random access switching, and the network device is a network device of the first cell.

[0212] According to an embodiment of the present disclosure, when a terminal switches to a first cell based on a no-access-at-anytime handover, the terminal may send first information to the first cell, where the first information is information about at least one transmit beam of the first cell determined by the terminal. A network device in the first cell may receive the first information sent by the terminal and, based on the information, determine information about at least one transmit beam of the first cell determined by the terminal, i.e., information about the transmit beam of the first cell deemed appropriate by the terminal. This ensures that the network device in the first cell can learn information about the transmit beam of the first cell deemed appropriate by the terminal, so that the network device can use the beam as a transmit beam in the first cell to communicate with the terminal, thereby ensuring the communication quality of the terminal in the first cell.

[0213] In some embodiments, the first cell may be an NR cell, or a cell of other radio access technology (RAT), such as an LTE (Long Term Evolution) cell. For example, when the first cell is an NR cell, the first cell may specifically be an NR NTN cell, or an NR TN cell.

[0214] In some embodiments, the information of at least one transmitting beam of the first cell determined by the terminal can play an auxiliary role for the network device. After the network device learns the information of the transmitting beam of the first cell that the terminal considers suitable, it can use the beam as the transmitting beam in the first cell to communicate with the terminal, or it can select other beams as the transmitting beam in the first cell to communicate with the terminal, depending on the implementation of the network device.

[0215] In some embodiments, the first information is carried in a radio resource control (RRC) message. For example, the terminal may send the first information to a network device of the first cell via an RRC message carrying the first information, wherein existing bits in the RRC message may be reused to carry the first information, or bits in the RRC message may be expanded to carry the first information.

[0216] In some embodiments, the radio resource control signaling includes: a radio resource control reconfiguration complete (RRCReconfigurationcomplete) message.

[0217] In some embodiments, the transmit beam of the first cell determined by the terminal includes at least one of the following:

[0218] The transmit beam of the first cell requested by the terminal;

[0219] The transmit beam of the first cell recommended by the terminal;

[0220] The transmitting beam of the first cell selected by the terminal.

[0221] In some embodiments, the information of the at least one transmit beam of the first cell includes at least one of the following:

[0222] second information, wherein the second information is associated with a reference signal received power of the synchronization signal, and the reference signal received power of the synchronization signal is greater than or equal to a first threshold;

[0223] The third information is associated with a reference signal received power of a channel state information reference signal, and the reference signal received power of the channel state information reference signal (Channel-State-Information Reference Signal, CSI RS) is greater than or equal to a second threshold.

[0224] For example, the second information includes at least one of the following: an index of a synchronization signal block (SSB index); and a reference signal received power (SS-RSRP) of a synchronization signal corresponding to the synchronization signal block.

[0225] In some embodiments, after switching to the first cell, the terminal can receive the CSI RS sent by the first cell on at least one beam, and determine the power of the received CSI RS as the CSI RS-RSRP, and then determine a CSI RS-RSRP greater than or equal to the first threshold in the at least one CSI RS-RSRP, and send the third information associated with the CSI RS corresponding to the determined CSI RS-RSRP as the information of the transmission beam to the first cell. The network equipment of the first cell can determine the CSI RS-RSRP associated with the received third information, and the CSI RS corresponding to the CSI RS-RSRP, and then determine that the beam corresponding to the CSI RS is the transmission beam of the first cell that the terminal considers appropriate.

[0226] For example, the third information includes at least one of the following: an index of a channel state information reference signal (CSI RS index); a reference signal received power of a channel state information reference signal (CSI RS-RSRP); an index of a synchronization signal block (SSB index), wherein the index of the synchronization signal block is associated with the channel state information reference signal; a reference signal received power of a synchronization signal of a synchronization signal block (SS-RSRP), wherein the synchronization signal block is associated with the channel state information reference signal.

[0227] FIG7 is a schematic flow chart of another method for receiving beam information according to an embodiment of the present disclosure. The beam information receiving method shown in this embodiment can be executed by a network device. As shown in FIG7 , the beam information receiving method further includes:

[0228] In step S701, priority information of each beam in at least one beam sent by a terminal is received, where the at least one beam includes multiple beams.

[0229] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure, and the present disclosure does not limit the specific implementation manner.

[0230] In some embodiments, the first information sent by the terminal to the first cell may include information about multiple transmit beams, that is, at least one beam may include multiple beams. In this case, the terminal may send priority information for each of the multiple beams to the first cell. The priority information may be sent to the first cell together with the first information or may be sent to the first cell separately. For example, the priority information may be sent to the first cell before or after the first information is sent.

[0231] The network equipment in the first cell can receive priority information for each of at least one beam transmitted by the terminal. Based on this information, the network equipment can determine the priority of multiple beams deemed suitable by the terminal. The suitability is ranked from high to low based on priority, with the beam with the highest priority being the beam deemed most suitable by the terminal. This facilitates the network equipment in the first cell to select a beam with a relatively high priority as the transmission beam for communication with the terminal in the first cell, thereby ensuring good communication quality for the terminal.

[0232] For example, the network device of the first cell can first determine whether the beam with the highest priority can be used to communicate with the terminal. When it is determined that the beam with the highest priority can be used to communicate with the terminal, the beam with the highest priority can be used as the transmission beam to communicate with the terminal in the first cell; and if it is determined that the beam with the highest priority cannot be used to communicate with the terminal, it can be further determined whether the beam with the second highest priority can be used to communicate with the terminal. When it is determined that the beam with the second highest priority can be used to communicate with the terminal, the beam with the second highest priority can be used as the transmission beam to communicate with the terminal in the first cell; and if it is determined that the beam with the second highest priority cannot be used to communicate with the terminal, it can be further determined whether the beam with the third highest priority can be used to communicate with the terminal. By analogy, the network device gives priority to selecting a beam with a relatively high priority that can be used to communicate with the terminal as the transmission beam of the first cell to communicate with the terminal.

[0233] An embodiment of the present disclosure further provides a communication method for use in a communication system, where the communication system includes a terminal and a network device.
