Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0174] To facilitate understanding, relevant concepts involved in the present disclosure are first introduced.

[0175] 1. Millimeter wave communication and terahertz communication

[0176] Millimeter wave communication has become a key technology for 5G NR. As low-frequency wireless spectrum resources are exhausted, the development and utilization of high-frequency millimeter wave and even terahertz communication technologies have become an inevitable trend.

[0177] In terms of spectrum allocation for terahertz wireless communications, the International Telecommunication Union (ITU) has completed the frequency division for various frequency services in the 100-275 GHz frequency range. The ITU has allocated 97.2 GHz of globally unified spectrum for land mobile and fixed services. Subsequently, four globally identified mobile service bands, namely 275-296 GHz, 306-313 GHz, 318-333 GHz, and 356-450 GHz, have been added to the 275-450 GHz frequency range for land mobile and fixed services, totaling 137 GHz of newly added spectrum bandwidth.

[0178] As an important candidate technology for future 6G communications, terahertz communication has been studied and discussed in key technologies, application visions and standardization. This has laid the foundation for research and industry consensus for terahertz communication to enter the IMT communication technology standards.

[0179] 2. Multi-antenna beamforming

[0180] With the use of millimeter-wave and terahertz frequency bands, the severe path loss faced by high-frequency bands needs to be addressed. Multi-antenna beamforming technology is an effective technical means to address path loss. As the antenna array grows, the spatial beams formed by the antenna array become narrower, and the number of beams also becomes enormous.

[0181] The embodiments of the present disclosure propose a beam management method. In some embodiments, NR beam management is performed based on orthogonal reference signals, wherein orthogonality includes time-frequency resource orthogonality and code domain orthogonality, and orthogonal reference signals need to be sent using different time-frequency resources. In other words, in some embodiments, the receiving end of the reference signal is distinguished by the different positions of the time-frequency resources where different reference signals are located. This means that in millimeter wave and terahertz communication scenarios, if beam management is still performed based on orthogonal reference signals, the resources occupied by the reference signals are huge, which will bring serious pilot overhead.

[0182] The beam management scheme proposed in the present disclosure can be applied to Multiple Input Multiple Output (MIMO) beam management. Optionally, the present disclosure proposes a beam management scheme based on non-orthogonal reference signals.

[0183] FIG2 is an interactive diagram of a beam management method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a beam management method for a communication system 100, the method comprising:

[0184] Step 2101: The network device 102 determines first information for a first reference signal.

[0185] In some embodiments, the first reference signal may be used for beam management.

[0186] In some embodiments, beam management may include beam measurement and beam indication. Terms such as "beam measurement," "channel measurement," and "reference signal measurement" are interchangeable. Optionally, beam management may also include beam measurement reporting, which is not limited in the present disclosure.

[0187] In some embodiments, the first reference signal may be used for beam measurement. "Using the first reference signal for beam measurement" may mean measuring the beam corresponding to the first reference signal, or in other words, measuring the first reference signal, or having the first reference signal measured, which is not a limitation of the present disclosure.

[0188] In some embodiments, the name of the first reference signal is not limited, and it can be a downlink reference signal, for example, it can be a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), or a synchronization signal block (Synchronization Signal / PBCH Block, SSB), etc., which is not limited in the embodiments of the present disclosure.

[0189] In some embodiments, the first reference signal may be one or more. In some embodiments, the first reference signal may be at least two.

[0190] In some embodiments, the first reference signals may be associated with beams of the antenna array of the network device 102. For example, each first reference signal may correspond to a beam.

[0191] In some embodiments, the first information may be used to configure a reference signal.

[0192] In some embodiments, the first information may be used to configure the first reference signal.

[0193] In some embodiments, the first information regarding the first reference signal may be used to assist a terminal in performing beam measurement on the first reference signal. The phrase "the first information is used to assist a terminal in performing beam measurement on the first reference signal" may mean that the terminal measures the beam corresponding to the first reference signal based on the first information, or in other words, the terminal measures the first reference signal based on the first information, or in other words, the first reference signal is measured based on the first information. This is not a limitation of the present embodiment.

[0194] In some embodiments, the name of the first information is not limited, and it can be, for example, "reference signal configuration information", "signal configuration information", "resource configuration information (Resource config)", etc. It can also be, for example, "first reference signal configuration information", "second reference signal configuration information", "first configuration information", "second configuration information", etc.

[0195] In some embodiments, the first information includes at least one of a first parameter and a second parameter corresponding to the first reference signal.

[0196] In some embodiments, the first parameter is used to generate a sequence of reference signals.

[0197] In some implementations, the reference signal may include a first reference signal, and the first parameter may be used to generate a sequence of the first reference signal.

[0198] In some embodiments, terms such as “trigger,” “generate,” “produce,” “enable,” and “occur” may be used interchangeably.

[0199] In some embodiments, the name of the first parameter is not limited, and may be, for example, a "sequence generator parameter", a "signal generation parameter", a "signal generation parameter", or the like.

[0200] In some embodiments, the second parameter is used to identify a sequence of the reference signal.

[0201] In some embodiments, the reference signal may be used to identify a sequence of the first reference signal.

[0202] In some embodiments, the name of the second parameter is not limited, and may be, for example, "sequence identifier", "signal identifier", "sequence ID", etc.

[0203] In some embodiments, for example, the first information may include at least one of a sequence generation parameter and a sequence identifier, wherein the sequence generation parameter may be used to generate a sequence of the first reference signal, the sequence identifier may be used to identify the sequence of the first reference signal, and the sequence identifier may be related to the sequence generation parameter.

[0204] In some embodiments, the first parameter may have an associated relationship with the second parameter.

[0205] In some embodiments, the first parameter and the second parameter may be associated with a reference signal.

[0206] In some embodiments, for example, the sequence generation parameter and the sequence identifier may be associated with the first reference signal. In the embodiments of the present disclosure, the terms "associated relationship" and "corresponding relationship" are interchangeable. The corresponding relationship may be a one-to-one relationship, a many-to-one relationship, or a one-to-many relationship, which is not limited in the present disclosure.

[0207] In some embodiments, when the first reference signal is at least two reference signals, the first information for the first reference signal satisfies the following conditions:

[0208] The first parameter and / or the second parameter of at least two first reference signals are different.

[0209] For example, the first reference signal #1 and the first reference signal #2 have different first parameters, such as different sequence generation parameters, or the first reference signal #1 and the first reference signal #2 have different second parameters, such as different sequence identifiers.

[0210] Under this condition, the first reference signal #1 and the first reference signal #2 use different transmission beams and can be distinguished spatially, or the receiving end can use an interference cancellation algorithm to separate different reference signals. That is, even if different reference signals are sent and / or received on the same time-frequency resources, the reference signals can still be distinguished, thereby saving the consumption of time-frequency resources when sending and / or receiving the reference signals.

[0211] In some embodiments, the first information may further include a time-frequency resource. Optionally, for network device 102, the time-frequency resource may be a time-frequency resource used to send the first reference signal, or in other words, the time-frequency resource on which the first reference signal is sent. Optionally, for terminal 101, the time-frequency resource may be a time-frequency resource used to receive the first reference signal, or in other words, the time-frequency resource on which the first reference signal is received.

[0212] In some embodiments, the time-frequency resource may be a sub-carrier in the frequency domain and / or a symbol in the time domain, for example, a resource element (RE).

[0213] In some embodiments, terms such as "resource block (RB)", "physical resource block (PRB)", "sub-carrier group (SCG)", "resource element group (REG)", "PRB pair", "RB pair", "resource element (RE)", and "sub-carrier" can be used interchangeably.

[0214] In some embodiments, when the first reference signal is at least two reference signals, the first information satisfies at least one of the following conditions:

[0215] The time-frequency resources of the at least two first reference signals are the same or partially overlap, and the first parameters and / or second parameters of the at least two first reference signals are different;

[0216] The time-frequency resources of the at least two first reference signals are different, and the first parameters and / or second parameters of the at least two first reference signals are the same or different.

[0217] For example, the first reference signal #1 and the first reference signal #2 have different first parameters or second parameters, such as different sequence generation parameters or sequence identifiers. There is no restriction on whether the time-frequency resources of the first reference signal #1 and the first reference signal #2 are the same. Their time-frequency resources can be the same or different, where the same can mean completely identical or partially overlapping.

[0218] Under this condition, the first reference signal #1 and the first reference signal #2 can be spatially distinguished, or the receiving end can use an interference cancellation algorithm to separate different reference signals. That is, even if different reference signals are sent and / or received on the same time-frequency resources, the reference signals can still be distinguished, thereby saving the consumption of time-frequency resources when sending and / or receiving the reference signals.

[0219] Alternatively, if the time-frequency resources of the first reference signal #1 and the first reference signal #2 are different, there is no restriction on whether the first or second parameters of the first reference signal #1 and the first reference signal #2 are the same. That is, there is no restriction on whether their sequence generation parameters or sequence identifiers are the same; their sequence generation parameters or sequence identifiers can be the same or different. For example, the first parameters of the first reference signal #1 and the first reference signal #2 may be the same, or the first parameters of the first reference signal #1 and the first reference signal #2 may be different, or the second parameters of the first reference signal #1 and the first reference signal #2 may be the same, or the second parameters of the first reference signal #1 and the first reference signal #2 may be different. Under this condition, the first reference signal #1 and the first reference signal #2 can be spatially distinguished, or the receiver can use an interference cancellation algorithm to separate the different reference signals.

[0220] In some embodiments, the network device 102 may determine the first information for the first reference signal based on at least one of its own number of cells, cell coverage, and the number of beams of the antenna array. For example, the network device 102 may determine the time-frequency resources occupied by the reference signal associated with each beam, and determine a signal sequence carried on the time-frequency resources. The signal sequence may be, for example, a downlink C-sequence and / or an uplink R-sequence. The network device 102 may determine generation parameters of the C-sequence and / or R-sequence. Different generation parameters result in different generated signal sequences.

[0221] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0222] In some embodiments, the terms "determine," "configure," and the like may be used interchangeably.

[0223] Step 2102 : The network device 102 sends first information for a first reference signal to the terminal 101 .

[0224] In some embodiments, terminal 101 receives first information for a first reference signal.

[0225] In some embodiments, network device 102 may send a physical downlink shared channel (PDSCH) to terminal 101. The PDSCH carries first information for the first reference signal. Optionally, terminal 101 receives the PDSCH, but is not limited thereto and may also receive other downlink information or downlink channels.

[0226] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0227] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0228] In some embodiments, terms such as "physical downlink shared channel (PDSCH)", "DL data", "physical downlink control channel (PDCCH)" can be used interchangeably, and terms such as "physical uplink shared channel (PUSCH)", "UL data", and "PUCCH" can be used interchangeably.

[0229] Step 2103: The network device 102 determines a first list of transmission configuration instructions.

[0230] In some embodiments, the first list is used to indicate TCI status.

[0231] In some embodiments, the name of the first list is not limited, and it can be, for example, a "TCI status list", a "TCI status identification list", etc.

[0232] In some embodiments, the first list may include one or more TCI states (TCI state), and the TCI state is associated with the TCI state identifier.

[0233] In some embodiments, the first list may be associated with a control resource set (CORESET).

[0234] In some embodiments, the TCI state can be used for uplink and downlink beam indication in beam management in the millimeter wave frequency band.

[0235] In some embodiments, the TCI state may be associated with a reference signal. Optionally, each TCI state may correspond to a downlink reference signal (e.g., an SSB or a CSI-RS). For example, the TCI state may include quasi-co-location information (QCL_Info), and QCL_Info may include a downlink reference signal SSB or a CSI-RS.

[0236] Step 2104: The network device 102 determines first information for the second reference signal.

[0237] In some embodiments, the second reference signal may be used for beam management.

[0238] In some embodiments, the second reference signal may be used for beam indication. "The second reference signal is used for beam indication" may mean indicating that the beam corresponding to a second reference signal is used for downlink reception and / or uplink transmission. "Used for downlink reception and / or uplink transmission" may mean used by a terminal for downlink reception and / or uplink transmission.

[0239] In some embodiments, terms such as "certain", "preseted", "preset", "setting", "indicated", "a certain", "some", "arbitrary", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "arbitrary A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0240] In some embodiments, the name of the second reference signal is not limited, and it can be a downlink reference signal, for example, it can be a channel state information reference signal (CSI-RS) or a synchronization signal block (Synchronization Signal / PBCH Block, SSB), etc., which is not limited in the embodiments of the present disclosure.

[0241] In some embodiments, the second reference signal may be associated with the TCI status flag.

[0242] In some embodiments, the second reference signal may be one or more. Alternatively, the second reference signal may be part or all of the first reference signal. In other embodiments, the second reference signal may be another reference signal other than the first reference signal, which is not limited in the present disclosure.

[0243] In some embodiments, the second reference signal may be the same as the first reference signal.

[0244] In some embodiments, the second reference signal may be a reference signal associated with a Transmission Configuration Indicator (TCI) state or a beam index.

Here, "the first information is used by the network device for beam indication" may mean that the network device indicates a beam for the terminal to perform downlink reception and / or uplink transmission according to the first information.

[0249] In some embodiments, the first information for the second reference signal includes at least a first parameter and / or a second parameter corresponding to the second reference signal.

[0250] In some embodiments, the first parameter and / or second parameter corresponding to the second reference signal may refer to the relevant description of the first parameter and the second parameter corresponding to the first reference signal in the above steps, which will not be repeated here.

[0251] In some embodiments, when the second reference signal is at least two reference signals, the conditions satisfied by the first information may refer to the relevant description of the conditions satisfied by the first configuration information in the above steps, and will not be repeated here.

[0252] In some embodiments, the first information for the second reference signal may further include time-frequency resources. For the time-frequency resources, reference may be made to the relevant description of the time-frequency resources in the above steps, which will not be repeated here.

[0253] In some embodiments, network device 102 may determine the first information for the second reference signal based on cell coverage. For example, network device 102 may determine a first list corresponding to the coverage of a cell, and the second reference signal may be associated with a TCI state in the first list. Network device 102 may determine the TCI state, thereby determining the second reference signal associated with each TCI state, and the first information for each second reference signal.

[0254] Step 2105 : The network device 102 sends a first list to the terminal 101 .

[0255] In some embodiments, terminal 101 receives a first list.

[0256] In some embodiments, network device 102 may send a downlink signal to terminal 101, where the downlink signal carries the first list. Optionally, terminal 101 receives a downlink signal, where the downlink signal may be radio resource control (RRC) signaling, media access control element (MAC CE) signaling, downlink control information (DCI) signaling, or other downlink signals or downlink channels, which are not limited in the embodiments of the present disclosure.

[0257] In some embodiments, the network device 102 may send the first list via a downlink channel. The downlink channel may be a PDSCH, but is not limited thereto, and may also be other downlink channels.

[0258] It should be understood that the timing and / or carrier at which the network device 102 sends the first list to the terminal 101 may be the same as or different from step 2102, and this disclosure does not limit this.

[0259] In some embodiments, terms such as "period", "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other, and terms such as "time", "timing", and "opportunity" can be replaced with each other.

[0264] Step 2107 : The network device 102 sends a first reference signal to the terminal 101 .

[0265] In some embodiments, terminal 101 may receive a first reference signal.

[0266] In some embodiments, the network device 102 may send a first reference signal based on the first information.

[0267] For example, the network device 102 may send a first reference signal corresponding to the first parameter or the second parameter on the time-frequency resources in the first configuration information for measurement by the terminal 101 .

[0268] Step 2108: Terminal 101 performs beam measurement on the first reference signal.

[0269] In some embodiments, the terminal 101 may perform beam measurement on the first reference signal to obtain a measurement result.

[0270] In some embodiments, the terminal 101 may measure all first reference signals sent by the network device 102, or may measure part of the first reference signals sent by the network device 102, which is not limited in the embodiments of the present disclosure.

The beam measurement performed by terminal 101 on the first reference signal may be a mobility-related measurement or a channel state information measurement, which is not limited in this disclosure. The measurement-related details are not further described herein.

[0272] In some embodiments, the measurement result includes third information and / or fourth information for all or part of the reference signal in the first reference signal.

[0273] In some embodiments, the third information is used to identify all or part of the reference signals in the first reference signals.

[0279] The description of the first parameter and the second parameter can be found in the description of the above steps and will not be repeated here.

[0280] In some embodiments, the fourth information is used to indicate a measurement value of a measurement quantity of all or part of the reference signals in the first reference signal.

[0281] In some embodiments, the name of the fourth information is not limited, and it can be, for example, "measurement result of measurement content", "measurement result of measurement parameter", etc.

[0282] In some embodiments, "measurement quantity" can be used interchangeably with descriptions such as measurement parameter and measurement quantity.

[0288] In some embodiments, the measurement quantity may also include any other parameter that can measure the beam quality, which is not limited in the embodiments of the present disclosure.

[0289] Step 2109 : Terminal 101 sends second information to network device 102 .

[0295] Step 2110: The network device 102 determines the fifth information.

[0296] In some embodiments, the fifth information is used to indicate: the beam used by the terminal for downlink reception and / or uplink transmission.

[0297] In some embodiments, the name of the fifth information is not limited, and it can be, for example, "beam indication information", "indication information", etc.

[0298] In some embodiments, the indication of the beam may be implemented by a TCI state flag or a beam index. In other words, the fifth information includes at least one of the following:

[0299] TCI status indicator;

[0300] Beam index.

[0301] For example, the network device 102 can configure a corresponding TCI state for each downlink signal or downlink channel, and indicate a reference signal associated with the TCI state to the terminal 101, so that the terminal 101 can use the beam corresponding to the reference signal for downlink reception and / or uplink transmission.

[0302] For another example, the network device 102 may indicate a beam index to the terminal 101 so that the terminal 101 may use the beam associated with the beam index for downlink reception and / or uplink transmission.

[0303] In some implementations, the fifth information may further include time, so that the terminal 101 uses a designated beam for transmission within the time corresponding to the fifth information.

[0304] In some embodiments, the network device 102 may determine the fifth information based on the first information.

[0305] In some embodiments, the network device 102 may determine the fifth information based on the first information for the second reference signal.

[0306] For example, the first information for the second reference signal may be configuration information of the second reference signal, where the second reference signal is a reference signal associated with a TCI state or a beam index. The network device 102 may determine, from the beam corresponding to the second reference signal, a beam used by the terminal for downlink reception and / or uplink transmission.

[0307] In some embodiments, the network device 102 may also determine the fifth information based on the first information for other reference signals, which is not limited in this disclosure.

[0308] In some embodiments, the network device 102 may determine the fifth information based on the first information and the second information.

[0309] For example, the network device 102 determines the reference signals with better measurement results from the received measurement results, and indicates the TCI status of these reference signals or the beam index of the beam corresponding to these reference signals to the terminal 101 as the fifth information.

[0310] In some embodiments, the manner in which the network device 102 determines the fifth information depends on the implementation of the network device 102 . The network device 102 may also determine the fifth information in other manners, which is not limited in this disclosure.

[0311] In some embodiments, the network device may indicate one or more beams through the fifth information.

[0312] Step 2111 : The network device 102 sends the fifth information to the terminal 101 .

[0313] In some embodiments, terminal 101 receives fifth information.

[0314] In some embodiments, step 2111 can refer to the description of "sending" in steps 2102, 2105, and 2106, which will not be repeated here.

[0315] It should be understood that the timing and / or carrier at which the network device 102 sends the fifth information to the terminal 101 may be the same as or different from steps 2102 , 2105 , and 2106 , and this disclosure does not limit this.

[0316] Step 2112: Terminal 101 determines the beam to be used for downlink reception and / or uplink transmission.

[0317] In some embodiments, the terminal 101 may determine the beam indicated by the fifth information based on the fifth information, and use the beam for downlink reception and / or uplink transmission.

[0318] For example, the fifth information includes the TCI status. When the terminal receives the fifth information:

[0319] The terminal believes that the network device can use the reference signal beam associated with the TCI state to transmit (corresponding to downlink reception) during a specific time period;

[0320] The terminal believes that in a specific time period, the receiving spatial filter corresponding to the reference signal associated with the TCI state can be used for transmission (corresponding to uplink transmission).

[0589] ii. The time-frequency resources of reference signal 1 are different from those of reference signal 2. The sequence used by reference signal 1 is the same as or different from the sequence used by reference signal 2.
