[0224] For example: the terminal may request the network device to perform uplink beam management, or the terminal may request the network device to perform uplink beam management while indicating that the uplink beam management is for one target object beam management or multiple target objects beam management, etc. For another example: the terminal may request the network device to perform downlink beam management, or the terminal may request the network device to perform downlink beam management while indicating that the downlink beam management is for one target object beam management or multiple target objects beam management, etc. For another example: the terminal may request the network device to perform uplink beam management and downlink beam management, or the terminal may request the network device to perform uplink beam management and downlink beam management while indicating that the uplink beam management and / or downlink beam management is for one target object beam management or multiple target objects beam management, etc. The embodiments of the present disclosure are not limited to this.

[0225] In some embodiments, the method further includes step 12: after the terminal sends the first information, the terminal further performs at least one of the following operations:

[0226] receiving beam management response information sent by the network device;

[0227] receiving a second reference signal for beam management sent by the network device;

[0228] A third reference signal for beam management is sent to the network device.

[0229] Example 1: When the first information sent by the terminal to the network device includes the measurement result of the first reference signal, and the measurement result of the first reference signal includes the measurement result of the available beam of the terminal (or the new beam measured by the terminal), if the measurement result of the first reference signal includes an available beam of the terminal (or a new beam measured by the terminal), and the network device determines that the available beam (or the new beam) is available, the beam management response information is sent to the terminal, indicating that the network device determines that the terminal can use the available beam (or the new beam), that is, beam management is implemented; or, if the measurement result of the first reference signal includes multiple available beams of the terminal (or multiple new beams measured by the terminal), and the network device determines one of the available beams (or determines one of the new beams), the beam management response information is sent to the terminal to indicate an available beam of the terminal, so that the terminal can know to use the beam for transmission, that is, beam management is implemented.

[0230] Example 2: When the first information sent by the terminal to the network device includes beam management request information, for example, the terminal sends beam management request information to request the network device to perform downlink beam management, the network device can send a second reference signal for beam management to the terminal based on the downlink beam management request of the terminal. The terminal receives the second reference signal and performs measurement, and reports the measurement result of the second reference signal to the network device. In this way, the network device can determine the beam available to the terminal (for example, determine the optimal beam) based on the measurement result of the second reference signal, thereby realizing downlink beam management.

[0231] In some embodiments, when the network device receives beam management request information sent by the terminal, it can also send beam management response information to the terminal to indicate that the network device confirms the beam management request of the terminal, or the response information can also trigger the transmission of the second reference signal (for example, the network device can send the second reference signal to the terminal after sending the beam management response information for triggering the sending of the second reference signal to the terminal), etc.

[0232] Example 3: When the first information sent by the terminal to the network device includes beam management request information, for example, the terminal sends the beam management request information to request the network device to perform uplink beam management, then after the terminal sends the beam management request information to the network device, it sends a third reference signal for beam management to the network device. The network device receives the third reference signal and performs measurement, so that the network device can determine the beam available to the terminal (for example, determine the optimal beam) based on the measurement result of the third reference signal, thereby realizing uplink beam management.

[0233] In some embodiments, when the network device receives beam management request information sent by the terminal, it can also send beam management response information to the terminal to indicate that the network device confirms the beam management request of the terminal, or the response information can also trigger the transmission of the third reference signal (for example, the terminal can send the third reference signal to the network device after receiving the beam management response information sent by the network device to trigger the sending of the third reference signal), etc.

[0234] Example 4: In the case where the first information sent by the terminal to the network device includes beam management request information, for example, the terminal sends beam management request information to request the network device to perform uplink beam management and downlink beam management, the specific terminal and network device side can implement beam management in combination with the processes of the above-mentioned Examples 2 and 3, which will not be repeated here.

[0235] Example 5: When the first information sent by the terminal to the network device includes: beam management request information (for example, the terminal sends beam management request information to request the network device to perform uplink beam management), and the measurement results of the terminal measuring the first reference signal sent by the network device, the network device side is informed that the terminal requests uplink beam management and downlink beam management. Specifically, the beam management can be implemented between the terminal and the network device side in combination with the processes of the above-mentioned Examples 1 and 3, which will not be repeated here.

[0236] In the disclosed embodiment, the first information sent by the terminal to the network device includes beam management request information and / or the measurement result of the first reference signal, so as to request the network device to perform beam management. After the terminal sends the first information, it also performs at least one of the following operations: receiving beam management response information sent by the network device; receiving the second reference signal for beam management sent by the network device; and sending a third reference signal for beam management to the network device, thereby implementing beam management. In this way, based on the terminal's active triggering of the request to the network device for beam management, the increase in signaling overhead caused by frequent measurement result reporting can be reduced, and the terminal side can be guaranteed to provide timely feedback on channel changes, solving the problems of high overhead and untimely channel feedback in the current beam management process.

[0237] In some embodiments, the beam management request information includes at least one of the following:

[0238] First request information, used to request the network device to perform beam management;

[0239] The second request information is used to trigger transmission of the second reference signal and / or the third reference signal.

[0240] For example, when the beam management request information includes the first request information, the beam management request information may explicitly instruct the network device to perform beam management. In some embodiments, the first request information may be used to request one or more of beam management, uplink beam management, and downlink beam management of at least one target object.

[0241] For example, the first request information may include: first indication information; the first indication information is used to request the network device to perform at least one of the following beam management:

[0242] Uplink beam management;

[0243] Downlink beam management;

[0244] Beam management of at least one target object; wherein the target object includes at least one of: a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set.

[0245] For example: the first indication information can be N bits (N is a positive integer, for example, N bits can be in the form of a bit map, etc.) or a specific sequence (for example, different sequences can be used to instruct the network device to perform uplink beam management or downlink beam management, or different sequences are used to instruct the network device to perform beam management of a target object, etc.), that is, the terminal can explicitly instruct the network device to perform one or more of beam management, uplink beam management, and downlink beam management of at least one target object through the first request information.

[0246] In some embodiments, the terminal sending the first information to the network device includes:

[0247] The terminal sends the first indication information to the network device at the first RO.

[0248] For example, the first indication information may be a preamble or a preamble sequence. That is, the terminal may instruct the network device to perform one or more of beam management, uplink beam management, and downlink beam management for at least one target object via a preamble sent to the network device at the first RO. This avoids adding additional signaling overhead and enables the terminal to proactively trigger a request to the network device to perform beam management.

[0249] In some embodiments, the first RO includes: a first RO group and a second RO group; wherein the first indication information sent on the first RO group is used to instruct the network device to perform uplink beam management, and the first indication information sent on the second RO group is used to instruct the network device to perform downlink beam management;

[0250] and / or,

[0251] The first RO includes: at least one third RO group; wherein the first indication information sent on each of the third RO groups is used to instruct the network device to perform beam management of a target object.

[0252] For example, a dedicated RO can be divided into subgroups. For example, two RO subgroups can be divided from the dedicated RO, and the preamble sent by one of the divided RO subgroups (i.e., the first indication information sent by the first RO group) is used to indicate the request information for uplink beam management; the preamble sent by the other RO subgroup (i.e., the first indication information sent by the second RO group) is used to indicate the request information for downlink beam management. Alternatively, multiple RO subgroups can be divided from the dedicated RO, and the preamble sent by each RO subgroup (i.e., the first indication information sent by each of the third RO groups) is used to indicate the beam management request information of a target object.

[0253] In some embodiments, when the first RO includes multiple RO groups, each RO group and preamble code may correspond to a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

[0254] In some embodiments, the terminal sending the first indication information to the network device at the first RO includes:

[0255] The terminal sends the first indication information to the network device using a first beam in a first RO, wherein the first beam includes at least one of the following:

[0256] A beam corresponding to a source reference signal in a TCI state currently being used by the terminal;

[0257] A beam corresponding to a reference signal associated with a TCI state currently being used by the terminal;

[0258] A beam corresponding to at least one reference signal determined by the terminal.

[0259] For example: when the terminal sends the preamble (i.e., the first indication information) to the network device at the first RO to request the network device to perform beam management, the terminal can determine a beam on its own and use the beam to send the preamble. For example, the terminal can select the RO corresponding to the current transmission beam (i.e., the beam currently being used by the terminal) to send the preamble (i.e., the first indication information) to indicate the corresponding beam management request. Alternatively, the terminal can also select a beam corresponding to a source reference signal in an activated TCI state, for example, the terminal selects a beam corresponding to a source reference signal in a currently effective (i.e., the terminal is currently using) TCI state from the activated TCI state to send the preamble (i.e., the first indication information) to indicate the corresponding beam management request. Alternatively, the terminal can also select a beam corresponding to a reference signal associated with an activated TCI state, for example, the terminal selects a beam corresponding to a reference signal associated with a currently effective (i.e., the terminal is currently using) TCI state from the activated TCI state to send the preamble (i.e., the first indication information) to indicate the corresponding beam management request, etc. The embodiments of the present disclosure are not limited to this.

[0260] In some embodiments, the first request information further includes at least one of the following:

[0261] The number of target objects for beam management. For example, in a multi-target scenario, the terminal may request the network device to perform beam management on at least one of the multiple target objects. Including the number of target objects for beam management in the first request information allows the network device to be informed of the number of target objects for which the terminal currently requests beam management.

[0262] The second indication information is used to request that the measurement results be reported in groups for each target object; for example: in a multi-target object scenario, when the terminal requests the network device to perform beam management on multiple target objects, the terminal can be requested to report the measurement results for multiple target objects in groups, for example, the result of one target object corresponds to one group, and of course it can also be other forms, etc., which are not limited to the embodiments of the present disclosure.

[0263] The number of groups of measurement results; for example: when the terminal requests group reporting of the measurement results of the target object, it can also request the network device to report the results of the target object in groups, such as one group corresponding to the result of one target object, or other forms, etc. The embodiments of the present disclosure are not limited to this.

[0264] For another example, when the beam management request information includes second request information, the beam management request information may implicitly instruct the network device to perform beam management. For example, if the second request information is used to trigger the transmission of the second reference signal, it indicates that the terminal requests the network device to perform downlink beam management; if the second request information is used to trigger the transmission of the third reference signal, it indicates that the terminal requests the network device to perform uplink beam management; if the second request information is used to trigger the transmission of the second reference signal and the third reference signal, it indicates that the terminal requests the network device to perform both uplink beam management and downlink beam management.

[0265] For another example: when the beam management request information includes the first request information and the second request information, the beam management request information can explicitly instruct the network device to perform beam management. For example: the first request information can indicate whether the terminal requests beam management, and the second request information can indicate that the terminal requests the network device to perform one or more of uplink beam management and downlink beam management (for example: the second request information is used to trigger the transmission of the second reference signal, which means that the terminal requests the network device to perform downlink beam management; the second request information is used to trigger the transmission of the third reference signal, which means that the terminal requests the network device to perform uplink beam management; the second request information is used to trigger the transmission of the second reference signal and the third reference signal, which means that the terminal requests the network device to perform uplink beam management and downlink beam management).

[0266] In some embodiments, the second request information includes but is not limited to at least one of the following:

[0267] a time offset value of the second reference signal and / or the third reference signal;

[0268] a time offset value set of the second reference signal and / or the third reference signal; wherein the time offset value set includes one or more time offset values;

[0269] identification information of the second reference signal and / or the third reference signal.

[0270] For example, when the second request information is used to trigger the transmission of a second reference signal, the second request information includes, but is not limited to, at least one of the following: a time offset value of the second reference signal, a time offset value set of the second reference signal, and identification information of the second reference signal. Alternatively, when the second request information is used to trigger the transmission of a third reference signal, the second request information includes, but is not limited to, at least one of the following: a time offset value of the third reference signal, a time offset value set of the third reference signal, and identification information of the third reference signal. Alternatively, when the second request information is used to trigger the transmission of both the second and third reference signals, the second request information includes, but is not limited to, at least one of the following: a time offset value of the second reference signal, a time offset value set of the second reference signal, identification information of the second reference signal, a time offset value of the third reference signal, a time offset value set of the third reference signal, and identification information of the third reference signal.

[0271] For example: when the second request information includes a set of time offset values ​​for the second reference signal and / or the third reference signal; wherein the time offset value set includes multiple time offset values, the network device can be provided with a time offset value to transmit the second reference signal and / or the third reference signal based on its own scheduling situation, so as to avoid conflicts with other channels or other reference signals when the network device transmits the second reference signal and / or the third reference signal.

[0272] The time offset value of the second reference signal is used to instruct the network device to send the second reference signal after receiving the beam management request information and the time offset value has elapsed. The time offset value of the third reference signal is used to instruct the terminal to send the third reference signal after sending the beam management request information and the time offset value has elapsed.

[0273] In some embodiments, the identification information includes at least one of the following:

[0274] Trigger status information; for example, the trigger status information may be a status information in the aperiodic channel state information (Channel State Information, CSI) reporting status information (CSI-AperiodicTriggerStateList) configured by the base station, or a CSI reporting ID (CSI-ReportConfigId), used to indicate activation of a CSI report associated with this status information, rather than all CSI reports, that is, triggering the transmission of the second reference signal and / or the third reference signal.

[0275] Resource or resource set information; for example: the resource or resource set information can be a CSI-RS resource ID or a CSI-RS resource set ID (NZP-CSI-RS-ResourceSetId), which is used to indicate the activation of a CSI-RS resource set, that is, triggering the transmission of the second reference signal and / or the third reference signal.

[0276] Carrier information; for example, the carrier information may be a carrier index, which may be used to indicate activation of a reference signal on a corresponding carrier, ie, triggering transmission of the second reference signal and / or the third reference signal.

[0277] BWP information; for example, the BWP information may be a BWP index, which may be used to indicate activation of a reference signal on a corresponding BWP, ie, trigger transmission of the second reference signal and / or the third reference signal.

[0278] In some embodiments, the terminal sends first information to the network device, including at least one of the following:

[0279] The terminal sends a MAC CE to the network device; wherein the MAC CE carries the first information;

[0280] The terminal sends the first information to the network device on the dedicated PUCCH resource configured by the network device for the terminal; for example: the network device can configure a dedicated PUCCH resource for the terminal (such as a periodic PUCCH resource), and the terminal can use the dedicated PUCCH resource to send the first information.

[0281] The terminal sends the first information to the network device on a dedicated PUSCH resource configured by the network device for the terminal; for example, the network device may configure a dedicated PUSCH resource (such as a periodic PUSCH resource) for the terminal, and the terminal may use the dedicated PUSCH resource to send the first information.

[0282] The terminal sends Msg3 to the network device during a random access process; wherein the Msg3 carries the first information;

[0283] The terminal sends MsgA to the network device during a random access process; wherein the MsgA carries the first information.

[0284] This embodiment provides multiple methods to ensure that the terminal can send the first information to the network device to request the network device to perform beam management. Furthermore, this embodiment can configure dedicated PUCCH resources and dedicated PUSCH resources to send the first information, thereby reducing information transmission conflicts or losses and ensuring the transmission reliability of the first information. Furthermore, the first information can be multiplexed in Msg3 or MsgA sent during the random access process to reduce additional signaling overhead.

[0285] In some embodiments, the terminal sending a MAC CE to the network device includes:

[0286] The terminal sends the MAC CE to the network device on a first resource; wherein the first resource includes at least one of the following:

[0287] The terminal requests the network device to allocate PUSCH resources through a scheduling request SR;

[0288] The terminal requests a PUSCH resource allocated by a network device through a dedicated preamble.

[0289] For example, when a terminal needs to request a network device to perform beam management, it may request the network device to allocate PUSCH resources through a scheduling request, or request the network device to allocate PUSCH resources through a set of dedicated ROs and preambles, and the terminal may send the first information on the allocated PUSCH resources to request the network device to perform beam management. Of course, in addition to this, if the terminal determines that there are currently available PUSCH resources, it is not necessary to request the network device to allocate PUSCH resources through a scheduling request or preamble, and send the first information on the available PUSCH resources to request the network device to perform beam management, etc. The embodiments of the present disclosure are not limited to this.

[0290] In some embodiments, the measurement results include but are not limited to at least one of the following:

[0291] Type indication information, used to indicate that the measurement result is a measurement result of one or more target objects; wherein the target object includes: at least one of a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set;

[0292] The identification information of the target object; for example: in a multi-target object scenario, if the terminal requests the network device to perform beam management on one or more target objects, the identification information of the target object can be used to enable the network device to know which target object or objects the terminal requests to perform beam management on.

[0293] The third indication information is used to indicate the transmission configuration indication TCI state of the target object being used by the terminal;

[0294] The resource indication information of the first reference signal; for example, the resource indication information may be an SSB resource indication (SSBRI) or a CSI-RS resource indication (CSI-RS Resource Indicator, CRI), etc.

[0295] The measurement amount of the first reference signal; for example, the measurement amount may be RSRP (such as L1-RSRP) and / or BLER, etc.

[0296] The number of measurement quantities of the first reference signal; for example, when the terminal reports the measurement result of the first reference signal, it can be reported in two parts, for example, the two parts include the number of measurement quantities and the measurement quantity.

[0297] In some embodiments, the first reference signal includes at least one of the following:

[0298] A source reference signal in the TCI state being used by the terminal;

[0299] Reference signals in the BFD RS set;

[0300] The source reference signal in the TCI state being used in the CORESET;

[0301] Reference signal in the NBI RS set of the beam failure recovery request;

[0302] DMRS;

[0303] A dedicated reference signal configured by a network device for the terminal; for example, the dedicated reference signal may be an SSB or a CSI-RS.

[0304] In this embodiment, the terminal may report the measurement result of the reference signal of the currently used beam (for example, the source reference signal in the TCI state being used by the terminal; or the reference signal in the BFD RS set; or the source reference signal in the TCI state being used in the CORESET; or DMRS; or the dedicated reference signal configured by the network device for the terminal, etc.) to the network device to request the network device to perform beam management (for example, when the currently used beam cannot meet the communication requirements, request the network device to change the beam); or the terminal may also report the measurement result of the reference signal of the new beam (for example, the reference signal in the NBI RS set of the beam failure recovery request or the dedicated reference signal configured by the network device for the terminal, etc.) to the network device to request the network device to perform beam management (for example, when the currently used beam cannot meet the communication requirements, the terminal measures the reference signal of the new beam and reports the measurement result to request the network device to change the beam), etc. The embodiments of the present disclosure are not limited to this.

[0305] In some embodiments, the terminal sending the first information to the network device includes:

[0306] When a beam management triggering event is satisfied, the terminal sends the first information to the network device; wherein the beam management triggering event includes at least one of the following:

[0307] A first measurement value of the first reference signal is less than a first threshold value;

[0308] A second measurement value of the first reference signal is greater than a second threshold value;

[0309] The first measurement quantity of the first reference signal is less than the first measurement quantity of the target signal; wherein the target signal is a reference signal in a first TCI state activated by at least one target object corresponding to the first reference signal; wherein the target object includes: at least one of a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set;

[0310] The second measurement quantity of the first reference signal is greater than the second measurement quantity of the target signal;

[0311] A first measurement value of a reference signal in an NBI RS set is measured to be greater than a first measurement value of a reference signal of a second beam; wherein the second beam is a beam currently being used by the terminal;

[0312] The second measurement quantity of the reference signal measured in the NBI RS set is less than the second measurement quantity of the reference signal of the second beam.

[0313] For example: the first reference signal may be the source reference signal in the TCI state currently being used by the terminal; or the reference signal in the BFD RS set; or the source reference signal in the TCI state currently being used in the CORESET; or DMRS; or a dedicated reference signal configured by the network device for the terminal, etc., wherein the first threshold values ​​corresponding to different types of first reference signals may be the same or different, and the second threshold values ​​corresponding to different types of first reference signals may also be the same or different. For example: the first threshold value corresponding to the source reference signal in the TCI state currently being used by the terminal and the first threshold value corresponding to the reference signal in the BFD RS set may be the same or different; the second threshold value corresponding to the source reference signal in the TCI state currently being used by the terminal and the second threshold value corresponding to the reference signal in the BFD RS set may be the same or different.

[0314] For example, in a single target object scenario, the target signal is the reference signal in the activated first TCI state corresponding to the first reference signal; for example, in a multiple target object scenario, the target signal is the reference signal in the activated first TCI state of the target object corresponding to the first reference signal. A target object can have one or more activated TCI states, and the first TCI state can be any one of them. The specific first TCI state can be indicated or configured by the network device side, or can also depend on terminal implementation, etc., but the embodiments of the present disclosure are not limited to this.

[0315] In some embodiments, the first measurement quantity is RSRP, and / or the second measurement quantity is BLER.

[0316] In some embodiments, the beam management trigger event is pre-set (for example, based on a protocol agreement), or the beam management trigger event is configured by the network device side (for example, after the network side determines the beam management trigger event, it is configured to the terminal).

[0317] In some embodiments, the beam management response information includes at least one of the following:

[0318] response information of the first information; for example: the response information may be response information for responding to the reception of the first information; for example: the response information may indicate that the network device side confirms the beam management request of the terminal (or may also indicate that the network device rejects or denies the beam management request of the terminal, etc.); or, if the measurement result of the first reference signal sent by the terminal includes the measurement result of a new beam, the response information may also indicate that the network device confirms that the new beam is an available beam (or may also indicate that the network device rejects or denies that the new beam is an available beam, etc.).

[0319] The fourth indication information is used to indicate the beam available to the terminal. For example, when the measurement result of the first reference signal sent by the terminal includes a new beam measurement result, the network device can select an available beam based on the new beam measurement result and notify the terminal through the fourth indication information.

[0320] In this embodiment, when the network device instructs the terminal to confirm an available beam requested by it through the beam management response information, or indicates an available beam to the terminal, beam management is implemented, and there is no need to perform beam management by transmitting a second reference signal and / or a third reference signal.

[0321] In some embodiments, the beam management response information includes fifth indication information, where the fifth indication information is used to trigger transmission of the second reference signal and / or the third reference signal;

[0322] The terminal receiving a second reference signal for beam management sent by the network device, and / or sending a third reference signal for beam management to the network device, including:

[0323] The terminal receives the second reference signal sent by the network device and / or sends the third reference signal to the network device according to the fifth indication information.

[0324] In this embodiment, if the terminal does not report the measurement result of the new beam, or the network device fails to determine the available beam for the terminal based on the measurement result of the first reference signal reported by the terminal (that is, the beam management response information does not indicate that the terminal confirms an available beam it requested, or does not indicate an available beam for the terminal), the network device may further trigger the transmission of the second reference signal and / or the third reference signal based on the fifth indication information. In this way, the terminal receives the second reference signal sent by the network device based on the fifth indication information, and / or sends the third reference signal to the network device, to implement beam management.

[0325] It should be noted that if the terminal triggers the transmission of the second reference signal and / or the third reference signal through the second request information when sending beam management request information to the network device, the network device can transmit the second reference signal and / or the third reference signal between the terminal based on the second request information without sending the fifth indication information to the terminal.

[0326] In some embodiments, the terminal receives beam management response information sent by the network device, including:

[0327] The terminal receives the DCI or MAC CE sent by the network device; wherein the DCI or MAC CE carries the beam management response information.

[0328] For example: the network device may use a first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2), which has the same Hybrid Automatic Repeat Request (HARQ) process number as the DCI of the PUSCH that schedules reporting of the measurement result, and the New Data Indicator (NDI) is flipped, to indicate the reception response of the first information or to confirm the indication of the available beam (that is, to carry the beam management response information through DCI). Alternatively, the network device may also use a second format DCI (for example, the second format DCI is DCI format (format) 1_1 / 1_2), and use part of the information field in the second format DCI as a special value (such as the HARQ process number, NDI flipping) to indicate the reception response of the first information or to confirm the indication of the available beam (that is, to carry the beam management response information through DCI). Of course, the DCI may also use the information field to indicate the beams available to the terminal, etc., and the embodiments of the present disclosure are not limited to this.

[0329] For example, the network device may transmit a MAC CE on the PDSCH, which is used to receive a response. When the terminal receives the MAC CE, it can know from the MAC CE that the network device has received the measurement results or beam management request reported by the terminal. In some embodiments, the network device may also determine a new beam (i.e., a beam available to the terminal) based on the measurement results reported by the terminal and indicate the new beam (i.e., a beam available to the terminal) in the MAC CE, so that the terminal can use the beam indicated by the MAC CE for transmission.

[0330] In some embodiments, the terminal receives downlink control signaling DCI sent by the network device, including at least one of the following:

[0331] The terminal receives the DCI sent by the network device on a dedicated CORESET;

[0332] The terminal uses the beam corresponding to the first reference signal to receive the DCI sent by the network device.

[0333] For example, the CORESET may be a CORESET-BFR for beam recovery. If a DCI is received in the CORESET, it indicates that the network device has received a reception response, i.e., the terminal knows that the network device has received the measurement results or beam management request reported by the terminal. In some embodiments, the network device may also determine a new beam (i.e., a beam available to the terminal) based on the measurement results reported by the terminal and indicate the new beam (i.e., a beam available to the terminal) in the DCI. Thus, after the terminal monitors the DCI in the dedicated CORESET, it can learn the new beam determined by the network device and use the beam indicated by the DCI for transmission.

[0334] In some embodiments, the DCI includes at least one of the following:

[0335] The first information field is used to indicate the response information of the first information; for example: the first information field can be an existing information field in the DCI (that is, the multiplexing is part of the information field in the DCI to indicate the response information), or the first information field can also be a newly added information field in the DCI, etc. The embodiments of the present disclosure are not limited to this.

[0336] A beam indicator field, where code points in the beam indicator field are used to indicate a target reference signal;

[0337] A TCI indication field, where a code point in the TCI indication field is used to indicate a target reference signal;

[0338] The target reference signal belongs to the first reference signal, and the beam corresponding to the target reference signal is a beam available to the terminal.

[0339] For example, the first reference signal may be a reference signal in the NBI RS set of the beam failure recovery request, or a dedicated reference signal configured by the network device for the terminal, etc. The embodiments of the present disclosure are not limited thereto.

[0340] In some embodiments, the information processing method further includes:

[0341] The terminal receives third information sent by the network device; wherein the third information is used to indicate activation or deactivation of the terminal requesting the network device to perform beam management.

[0342] In this embodiment, the network device may send third information to the terminal to instruct it to activate or deactivate the terminal's request for the network device to perform beam management. For example, when the network device instructs the terminal to activate the terminal's request for the network device to perform beam management through the third information, the terminal may proactively send first information to the network device to request the network device to perform beam management. If the network device instructs the terminal to deactivate the terminal's request for the network device to perform beam management through the third information, this indicates that the network device does not want the terminal to proactively send the first information to the network device to request the network device to perform beam management. In this case, the terminal is not allowed to proactively request the network device to perform beam management.

[0343] In the embodiment of the present disclosure, on the one hand, the terminal determines the beam management request by itself, and indicates the uplink, downlink or multi-TRP beam management in the reported beam management request. Furthermore, the terminal can also use this beam management request to directly trigger the transmission of the downlink or uplink reference signal to start the beam management process of the terminal. On the other hand, the terminal can directly report the measurement results of a single TRP or the measurement results of the reference signals of one or more TRPs in a multi-TRP scenario to provide the network equipment with beam management based on the measurement results, or select the optimal beam, or confirm the optimal beam, etc., and start the beam management process of the terminal or indicate the optimal beam to the terminal. Furthermore, the reporting process of the terminal can be activated or deactivated by the network side based on application requirements. This solution ensures that the network side can promptly know whether the beam of the terminal needs to be changed, and supports TRP-level beam management to ensure network performance.

[0344] The terminal involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called User Equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. 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), and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0440] The information processing method disclosed herein is described below with reference to specific embodiments:

[0441] Example 1:

[0442] A beam management trigger event is configured for the terminal based on a protocol agreement or by a network device (such as a base station); wherein the beam management trigger event includes but is not limited to one or more of the following events:

[0443] Event 1: The RSRP of the source reference signal in the TCI state currently being used by the terminal (or referred to as the currently effective TCI state) is less than the first threshold or the BLER is greater than the second threshold.

[0444] Event 2: The RSRP of the reference signal in the BFD-RS set is less than the first threshold or the BLER is greater than the second threshold.

[0445] Event 3: The RSRP of the reference signal implicitly determined during beam failure recovery (i.e., the source reference signal in the TCI state used by the CORESET) is less than the first threshold or the BLER is greater than the second threshold.

[0446] Event 4: The RSRP of the reference signal in the NBI-RS set is greater than the RSRP value of the source reference signal in the currently valid TCI state, or the BLER of the reference signal in the NBI-RS set is less than the BLER of the source reference signal in the currently valid TCI state.

[0447] Event 5: The RSRP of the DMRS received by the terminal is less than the first threshold or the BLER is greater than the second threshold.

[0448] Event 6: The RSRP of the source reference signal in the currently valid TCI state is less than the RSRP of the source reference signal in the TCI state activated by the MAC CE, or the BLER of the source reference signal in the currently valid TCI state is greater than the BLER of the source reference signal in the TCI state activated by the MAC CE.

[0449] Event 7: The RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the source reference signal in the first TCI state activated by the corresponding target object (for example, this scenario is applied to beam management triggering for one or more target objects), or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the source reference signal in the first TCI state activated by the corresponding target object. The target object includes: at least one of a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set; the first TCI state can be any activated TCI state of the target object, or can also be an activated TCI state indicated by the network side or determined by the terminal itself, etc. The embodiments of the present disclosure are not limited to this.

[0450] Event 8: The RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the first SSB, or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the first SSB. The first SSB may be an SSB indicated by the network or determined by the terminal, but the embodiments of the present disclosure are not limited thereto.

[0451] Event 9: The RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the periodic or semi-persistent reference signal configured by the base station, or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the periodic or semi-persistent reference signal configured by the base station. For example, the periodic or semi-persistent reference signal configured by the base station may be the CSI-RS.

[0452] It should be noted that the first threshold values ​​in the above event 1, event 2, event 3 and event 5 may be the same or different, and the second threshold values ​​may also be the same or different.

[0453] The terminal performs measurements based on the above beam management triggering events. When it determines that the measurement results meet one or more of the above beam management triggering events, it sends beam management request information to the network device. The terminal can use one or more of the following methods to send beam management request information to the network device:

[0454] Method 1: Use a dedicated preamble and RO to send the beam management request information.

[0455] In some embodiments, the dedicated preamble and ROs are divided into subgroups. For example, the preamble sent on one RO subgroup indicates uplink beam management request information, while the preamble sent on another RO subgroup indicates downlink beam management request information. Alternatively, the preamble sent on each RO subgroup indicates beam management request information for a target object.

[0456] In some embodiments, each RO group and preamble corresponds to an SSB or CSI-RS. The terminal may select the RO corresponding to the current transmission beam (i.e., the beam currently being used by the terminal) to send the preamble to indicate a corresponding beam management request, or the terminal may select an RO corresponding to a source reference signal in an activated TCI state to send the preamble to indicate a corresponding beam management request, etc. The embodiments of the present disclosure are not limited thereto.

[0457] Method 2: The terminal requests the network device to allocate PUSCH resources through a scheduling request, and sends the beam management request information on the allocated PUSCH resources. Alternatively, if there are currently available PUSCH resources, the terminal may not need to make a scheduling request and send the beam management request on the available PUSCH resources.

[0458] For example, the terminal sends a MAC CE on the PUSCH resource, and the MAC CE carries the beam management request information. In some embodiments, the MAC CE may also include a measurement result of a reference signal that triggers the transmission of the MAC CE (for example, when one or more of the aforementioned beam management triggering events are met, the MAC CE is triggered to transmit, and the MAC CE carries the measurement result of the reference signal that meets the beam management triggering event).

[0459] In some embodiments, the beam management request information may be used to request the network device to perform one or more of uplink beam management, downlink beam management, and beam management of at least one target object. The target object includes at least one of a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set.

[0460] Method 3: The terminal may send beam management request information to the network device during the RACH process. For example, the terminal may send Msg3 or MsgA to the network device during the RACH process, where the Msg3 or MsgA carries the beam management request information.

[0461] Method 4: The network device configures a dedicated PUCCH resource or PUSCH resource for the terminal (for example, a periodic PUCCH resource or PUSCH resource), and the terminal can send the beam management request information on the PUCCH resource or PUSCH resource.

[0462] For example, taking the example of a terminal requesting a network device to perform downlink beam management through the beam management request information, the beam management request information includes but is not limited to at least one of the following information:

[0463] Identification information of the reference signal to be triggered (i.e., the second reference signal);

[0464] Transmit transmission offset information (eg, a time offset value or a set of time offset values) of the reference signal to be triggered (ie, the second reference signal).

[0465] In some embodiments, the identification information may include, but is not limited to, at least one of the following:

[0466] Trigger status information; for example, a status information in the aperiodic CSI reporting status information (CSI-AperiodicTriggerStateList) configured by the base station, or a CSI reporting ID (CSI-ReportConfigId), indicating activation of a CSI reporting associated with this status information, rather than all CSI reporting.

[0467] Resource or resource set information; for example, CSI-RS resource set ID (NZP-CSI-RS-ResourceSetId), indicating that a CSI-RS resource set is activated.

[0468] Carrier information; for example, a carrier index, indicating activation of a reference signal on the corresponding carrier.

[0469] BWP information; for example, BWP index, indicating activation of the reference signal on the corresponding BWP.

[0470] In some embodiments, when the beam management request information includes a time offset value for the transmission of the reference signal to be triggered (i.e., the second reference signal), or when the time offset value set includes a time offset value, it means that the network device side receives the beam management request information and sends the second reference signal (such as CSI-RS) after the length of the time offset value has passed.

[0471] In some embodiments, when a terminal requests to transmit a second reference signal, a conflict may occur with an existing schedule on the network device side. Therefore, the terminal may include multiple time offset values ​​for transmitting the reference signal to be triggered (i.e., the second reference signal) in the beam management request information, or the time offset value set may include multiple time offset values. The network device side selects a time offset value from the multiple time offset values ​​and sends the second reference signal according to the time offset value, thereby avoiding a conflict between the terminal's request to transmit the second reference signal and the existing schedule on the network device side.

[0472] The beam management request information includes multiple time offset values ​​or the time offset value set includes multiple time offset values. In some embodiments, the following scheme is used for implementation:

[0473] Solution 1: The network device configures a set of time offset values ​​(offset) for the terminal, as shown in Table 1.

[0474] Table 1

[0475] In some embodiments, the unit of the offset value may be a time slot.

[0476] For example: when the terminal needs to indicate multiple time offset values ​​in the beam management request information, it can be indicated in the form of a bitmap. For example, taking Table 1 as an example, when the terminal indicates "0111" through a 4-bit bitmap, it means that the candidate time offset values ​​are 4, 8, and 10 time slots. If the terminal sends the beam management request information in time slot n, the network device side can select a time offset value from the time offset values ​​of 4, 8, and 10 time slots according to the current scheduling situation of the network device side after receiving the beam management request information. If the network device side determines to send the second reference signal according to the time offset value of 10 time slots based on the current scheduling situation, the network device can send the second reference signal in time slot n+10 for downlink beam management in response to the beam management request of the network device. Correspondingly, the terminal can detect the second reference signal in time slot n+4, time slot n+8, and time slot n+10 respectively, and the terminal will detect its requested second reference signal (such as CSI-RS) in time slot n+10. The terminal measures the second reference signal and feeds back the measurement results. The network device can determine the beam available to the terminal based on the measurement results of the second reference signal, that is, realize downlink beam management based on terminal side request.

[0477] Solution 2: The terminal indicates the time window length in the beam management request information, which represents the time offset value for transmitting the second reference signal.

[0478] For example, the terminal sends a beam management request message to the network device at time n, and starting from time n, detects the second reference signal (such as CSI-RS) within the time window length. If the terminal does not detect the second reference signal within the time window length, the terminal can resend the beam management request message to re-request the network device to perform beam management. If the terminal detects the second reference signal within the time window length, the terminal measures the second reference signal and feeds back the measurement result. The network device can determine the beam available to the terminal based on the measurement result of the second reference signal, that is, implement downlink beam management based on the terminal side request.

[0479] In some embodiments, the time window length may also be predefined by the system (eg, agreed upon by a protocol) and known to both the terminal and the network device.

[0480] Solution 3: The terminal may indicate a time offset value in the beam management request information, indicating that the beam management request information has the highest priority.

[0481] For example, after receiving the beam management request, the network device will send a second reference signal (such as a CSI-RS) at the position corresponding to the time offset value. Accordingly, the terminal will also detect the requested second reference signal at the position corresponding to the time offset value. If the terminal detects the second reference signal (such as a CSI-RS), it will measure the second reference signal and feedback the measurement result. The network device can determine the available beam for the terminal based on the measurement result of the second reference signal, thus implementing downlink beam management based on the terminal's request.

[0482] Furthermore, the network device may also send a third message to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, and the start information is used to start or activate the terminal's request for the network device to perform beam management (that is, indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (that is, indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling, etc. The embodiments of the present disclosure are not limited to this.

[0483] Example 2:

[0484] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0485] The terminal performs measurements based on the above beam management trigger events. When it is determined that the measurement results meet one or more of the above beam management trigger events, the terminal reports the measurement results to the network device (here referred to as the measurement results of the first reference signal, that is, the measurement results of the reference signal measured by the terminal).

[0486] In some embodiments, the terminal may report the measurement result of the first reference signal to the network device in one or more of the following ways:

[0487] Method 1: The terminal requests the network device to report the measurement result of the first reference signal through a dedicated RO and preamble (or preamble sequence), and at the same time requests the network device to allocate PUSCH resources. In this way, the terminal can send the measurement result of the first reference signal on the PUSCH resource allocated by the network device. Alternatively, if the terminal determines that there are available PUSCH resources, the terminal does not need to request the network device to allocate PUSCH resources through a dedicated RO and preamble, and sends the measurement result of the first reference signal on the available PUSCH resource.

[0488] Method 2: The terminal requests the network device to allocate PUSCH resources through a scheduling request, and the terminal transmits the measurement result of the first reference signal on the allocated PUSCH resource. Alternatively, if there are currently available PUSCH resources, the terminal may not need to transmit a scheduling request and transmit the measurement result of the first reference signal on the available PUSCH resource. For example, the terminal transmits a MAC CE on the PUSCH resource, and the MAC CE carries the measurement result of the first reference signal.

[0489] Method 3: The terminal may send the measurement result of the first reference signal to the network device during the RACH process. For example, the terminal may send Msg3 or MsgA to the network device during the RACH process, where the Msg3 or MsgA carries the measurement result of the first reference signal.

[0490] Method 4: The network device configures a dedicated PUCCH resource or PUSCH resource (for example, a periodic PUCCH resource or PUSCH resource) for the terminal, and the terminal may send the measurement result of the first reference signal on the PUCCH resource or PUSCH resource.

[0491] In some embodiments, the measurement result of the first reference signal is a measurement result that satisfies the one or more beam management triggering events, and the measurement result includes but is not limited to at least one of the following:

[0492] Type indication information is used to indicate that the measurement result is a measurement result of one or more target objects; wherein the target object includes: at least one of a CORESET pool, a CORESET group, a resource set, a TRP, and a BFD RS set; that is, the type indication information can indicate whether the measurement result reporting of the first reference signal triggered by the terminal is a measurement result reporting of a single target object scenario (such as a single TRP) or a measurement result reporting of multiple target objects scenario (such as multiple TRPs).

[0493] New beam measurement results; for example, SSBRI and its corresponding resource layer 1 reference signal received power (L1-RSRP), or CRI and its corresponding resource layer 1 reference signal received power (L1-RSRP).

[0494] In some embodiments, if the type indication information indicates that the measurement result is a measurement result of multiple target objects, the measurement result may further include at least one of the following information:

[0495] The identification information of the target object is used to indicate which target object the measurement result corresponds to. For example, if the target object is a resource set, the identification information may be a resource set ID; if the target object is a CORESET pool, the identification information may be a CORESET pool ID, etc.

[0496] After receiving the measurement results reported by the terminal, the network device may send beam management response information to the terminal. The beam management response information may include but is not limited to at least one of the following:

[0497] Response information in response to the reception of the measurement result; for example: the response information can indicate that the network device confirms the beam management request of the terminal (or can also indicate that the network device rejects or denies the beam management request of the terminal, etc.); or, the response information indicates confirmation of the new beam requested by the terminal (or can also indicate rejection or denial of the new beam requested by the terminal, etc.), for example, the measurement result of the first reference signal reported by the terminal includes the measurement result of a beam available to the terminal (that is, a new beam measurement result), and when the network device determines that the beam is available, the response information can be used to instruct the terminal to use the beam.

[0498] The fourth indication information is used to indicate the beam available to the terminal. For example, when the measurement result includes a new beam measurement result, the network device can select an available beam based on the new beam measurement result and notify the terminal through the fourth indication information.

[0499] For example, the network device may also feed back beam management response information in different ways according to the number of measurement results reported by the terminal.

[0500] For example, when a terminal reports multiple measurement results, the network device needs to receive a response and further perform beam selection based on the measurement results. In some embodiments, the following method is used:

[0501] Method 1: The network device uses a first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2), which has the same Hybrid Automatic Repeat Request (HARQ) process number as the DCI of the PUSCH that schedules reporting of the measurement result, and the New Data Indicator (NDI) is flipped to indicate a received response. In some embodiments, the network device also uses the existing information field in the first format DCI to indicate a new beam (i.e., a beam available to the terminal). For example: using the CSI request field in the first format DCI to indicate a new beam (i.e., a beam available to the terminal).

[0502] Alternatively, the network device may also use a second format of DCI (for example, the second format of DCI is DCI format1_1 / 1_2), and use part of the information field in the second format of DCI as a special value (such as HARQ process number, NDI flip) to indicate the reception response. In some embodiments, the network device may also use the TCI indication field in the second format of DCI to indicate a new beam (i.e., a beam available to the terminal).

[0503] In some embodiments, in addition to using the existing information field in the DCI to receive responses, the network device may also add a new information field in the DCI to receive responses, etc., or add a new indication field in the DCI to indicate a new beam (i.e., a beam available to the terminal), etc. The embodiments of the present disclosure are not limited to this.

[0504] Method 2: The terminal monitors a dedicated CORESET. For example, the CORESET may be a CORESET-BFR for beam recovery. If a DCI is received in the CORESET, it indicates that the network device side has received a response, that is, the terminal knows that the network device has received the measurement results reported by it. In some embodiments, the network device may also determine a new beam (i.e., a beam available to the terminal) based on the measurement results reported by the terminal and indicate the new beam (i.e., a beam available to the terminal) in the DCI. Thus, after the terminal monitors the DCI in the dedicated CORESET, it can learn about the new beam determined by the network device side (i.e., a beam available to the terminal) and use the beam indicated by the DCI for transmission.

[0505] Method 3: The network device can transmit a MAC CE on the PDSCH. This MAC CE is used to receive a response. When the terminal receives the MAC CE, it can know from the MAC CE that the network device has received the measurement results reported by the terminal. In some embodiments, the network device can also determine a new beam (i.e., a beam available to the terminal) based on the measurement results reported by the terminal and indicate the new beam (i.e., a beam available to the terminal) in the MAC CE, so that the terminal can use the new beam (i.e., a beam available to the terminal) indicated by the MAC CE for transmission.

[0506] For another example, when the terminal reports a single measurement result, the base station only needs to receive a response. In some embodiments, the following method is used:

[0507] Mode 1: After the terminal reports a single measurement result, it uses the beam corresponding to the measurement result to monitor the dedicated CORESET. The network device transmits DCI in this CORESET using the beam corresponding to the measurement result reported by the terminal, and responds to the reception. If the terminal receives DCI in this CORESET, it knows that the network device has received the measurement result reported by it. In some embodiments, if the measurement result reported by the terminal includes the measurement result of a new beam (i.e., a beam available to the terminal), the terminal receiving DCI in this CORESET may also indicate that the network device confirms that the beam is a beam available to the terminal. The terminal can then use this beam for transmission.

[0508] Method 2: The network device uses a first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2), which has the same HARQ process number as the DCI of the PUSCH that schedules reporting of the measurement result, and flips the NDI to perform a reception response. If the terminal receives the DCI in the first format, it knows that the network device has received the measurement result reported by it. In some embodiments, if the measurement result reported by the terminal includes the measurement result of a new beam (that is, a beam available to the terminal), the DCI in the first format may also indicate that the network device confirms that the beam is a beam available to the terminal. The terminal can then use the beam for transmission.

[0509] Method 3: The network device can transmit a MAC CE on the PDSCH. This MAC CE is used to acknowledge reception. When the terminal receives this MAC CE, it can know from this MAC CE that the network device has received the measurement results reported by the terminal. In some embodiments, if the measurement results reported by the terminal include measurement results for a new beam (i.e., a beam available to the terminal), the MAC CE can also indicate that the network device confirms that the beam is available to the terminal. The terminal can then use this beam for transmission.

[0510] Furthermore, the network device may also send third information to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, where the start information is used to start or activate the terminal's request for the network device to perform beam management (i.e., indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (i.e., indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling.

[0511] Example 3:

[0512] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0513] The terminal performs measurements based on the above beam management triggering events. When it is determined that the measurement results meet one or more of the above beam management triggering events, the terminal sends beam management request information to the network device. Specifically, the terminal can use one or more of the methods 1 to 4 of the above embodiment 1 to send beam management request information to the network device, which will not be repeated here.

[0514] For example, a terminal requests a network device to perform downlink beam management using beam management request information. The terminal uses a dedicated set of ROs and preambles to request the network device to perform downlink beam management. After receiving the preamble, the network device can use a first-format DCI (e.g., the first-format DCI is DCI format 0_1 / 0_2) to trigger the transmission of a second reference signal (e.g., an aperiodic CSI-RS) for downlink beam management.

[0515] In some embodiments, the DCI in the first format can also serve as a response to the terminal's request for downlink beam management. For example: after sending the beam management request information, the terminal detects the downlink DCI within a time window length. If a DCI that triggers the transmission of a second reference signal (such as a non-periodic CSI-RS) is received within this time window length, the terminal believes that the network device confirms the terminal's downlink beam management request. Otherwise, the terminal believes that the network device has not correctly received the terminal's downlink beam management request, and the terminal will resend the beam management request information of the downlink beam management request.

[0516] In order to distinguish that the DCI in the first format is used to respond to the beam management request of the terminal, in some embodiments, similar to embodiment 2, the network device may send the DCI in the first format on a dedicated CORESET to receive the response.

[0517] It should be noted that the above embodiment is described by taking the example of the terminal requesting the network device to perform downlink beam management through beam management request information. When the terminal requests the network device to perform uplink beam management through beam management request information, the network device can also use the first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2), or use the second format DCI (for example, the second format DCI is DCI format 1_1 / 1_2) to trigger the transmission of the third reference signal (for example, non-periodic SRS) to achieve uplink beam management. In addition, the network device can also use the DCI to respond to the uplink beam management requested by the terminal, etc., which will not be repeated here.

[0518] It should also be noted that the terminal can also request the network device to perform downlink beam management and uplink beam management through beam management request information. Accordingly, the network device side can use the first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2) to trigger the transmission of the second reference signal (for example, non-periodic CSI-RS) to achieve downlink beam management, and at the same time trigger the transmission of the third reference signal (for example, non-periodic SRS) to achieve uplink beam management; or, the network device side can use the first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2) to trigger the transmission of the second reference signal (for example, non-periodic CSI-RS) to achieve downlink beam management, and use the second format DCI (for example, the second format DCI is DCI format 1_1 / 1_2) to trigger the transmission of the third reference signal (for example, non-periodic SRS) to achieve uplink beam management. In addition, the network device can also use the DCI to respond to the uplink beam management and downlink beam management requested by the terminal, etc., which will not be repeated here.

[0519] Furthermore, the network device may also send third information to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, where the start information is used to start or activate the terminal's request for the network device to perform beam management (i.e., indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (i.e., indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling.

[0520] Example 4:

[0521] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0522] For example, in a multi-target object scenario (such as multiple TRPs), the terminal operates in a multi-TRP mode, and the multiple TRPs include TRP0 and TRP1. For example: the terminal determines that the above-mentioned event 7 is satisfied (the RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the source reference signal in the first TCI state activated by the corresponding target object, or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the source reference signal in the first TCI state activated by the corresponding target object), that is, a TRP-level event is triggered.

[0523] Taking downlink beam management as an example, the terminal can request the network device to perform downlink beam management of one or more TRPs in the multiple TRPs by reporting beam management request information. Specifically, the terminal can use one or more of the methods 1 to 4 of the above embodiment 1 to send the beam management request information to the network device, which will not be repeated here.

[0524] For example, when a terminal requests a network device to perform downlink beam management of TRP0 by reporting beam management request information, the beam management request information can also be used to trigger the transmission of the second reference signal (aperiodic CSI-RS) of TRP0. The beam management request information includes but is not limited to at least one of the following:

[0525] identification information of the second reference signal;

[0526] Transmission offset information of the second reference signal (eg, a time offset value or a set of time offset values).

[0527] In some embodiments, the identification information may include, but is not limited to, at least one of the following:

[0528] Trigger status information; for example, a status information in the aperiodic CSI reporting status information (CSI-AperiodicTriggerStateList) configured by the base station, or a CSI reporting ID (CSI-ReportConfigId), indicating activation of a CSI reporting associated with this status information, rather than all CSI reporting.

[0529] Resource or resource set information; for example: for beam management of multiple TRPs, one CSI report configuration (CSI-ReportConfig) is associated with two CSI-RS resource sets, that is, one CSI-ReportConfig is associated with two non-zero power CSI-RS resource sets (NZP-CSI-RS-ResourceSet). Each CSI-RS resource set corresponds to one TRP. The resource or resource set information here can be CSI-RS resource set indication information, such as using the identification information of the CSI-RS resource set to indicate the associated first CSI-RS resource set (i.e., TRP0), and can also indicate the associated second CSI-RS resource set (i.e., TRP1); or, the resource or resource set information can also be the ID of the CSI-RS resource set (such as NZP-CSI-RS-ResourceSetId), etc. The embodiments of the present disclosure are not limited to this.

[0530] Taking the beam management request information used to request the network device to perform beam management of TRP0 as an example, for example, two bits can be used to indicate the TRP for which beam management is requested, with each bit corresponding to a CSI-RS resource set (i.e., a TRP). For example, if these two bits are "10", it indicates the first CSI-RS resource set associated with the triggering CSI reporting (i.e., requesting beam management of TRP0).

[0531] In some embodiments, the transmission offset information of the second reference signal included in the beam management request information is similar to that in Example 1 and will not be repeated here.

[0532] Furthermore, based on a method similar to that of Example 1, after receiving the beam management request information sent by the terminal, the network device determines a time offset value for avoiding scheduling conflicts, and sends a second reference signal (such as a non-periodic CSI-RS signal) corresponding to TRP0 at a time domain position corresponding to the time offset value. The terminal receives the second reference signal (such as a non-periodic CSI-RS signal) for measurement, and reports the measurement result (such as L1-RSRP) of the second reference signal (such as a non-periodic CSI-RS signal) to the network device, so that the network device can determine the beam available to the terminal (such as the optimal beam) based on the measurement result of the second reference signal, that is, to realize downlink beam management.

[0533] In some embodiments, when the terminal reports the measurement result of the second reference signal (such as the aperiodic CSI-RS signal) to the network device, it may only report the measurement result of the second reference signal (such as the aperiodic CSI-RS signal) of TRP0, without reporting the reference signal measurement result of TRP1 for which beam management is not triggered. In this case, the TCI state and / or beam of the TRP1 for which the measurement result is not reported remains unchanged.

[0534] Furthermore, the network device may also send third information to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, where the start information is used to start or activate the terminal's request for the network device to perform beam management (i.e., indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (i.e., indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling.

[0535] Example 5:

[0536] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0537] For example, in a multi-target object scenario (such as multiple TRPs), the terminal operates in a multi-TRP mode, and the multiple TRPs include TRP0 and TRP1. For example, if the terminal determines that the above-mentioned event 7 is satisfied (the RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the source reference signal in the first TCI state activated by the corresponding target object, or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the source reference signal in the first TCI state activated by the corresponding target object), that is, a TRP-level event is triggered.

[0538] Taking downlink beam management as an example, the terminal can request the network device to perform downlink beam management of one or more TRPs in the multiple TRPs by reporting beam management request information. Specifically, the terminal can use one or more of the methods 1 to 4 of the above embodiment 1 to send the beam management request information to the network device, which will not be repeated here.

[0539] For example, when a terminal requests a network device to perform downlink beam management of TRP0 by reporting beam management request information, the beam management request information can also be used to trigger the transmission of the second reference signal (aperiodic CSI-RS) of TRP0. The beam management request information includes but is not limited to at least one of the following:

[0540] identification information of the second reference signal;

[0541] Transmission offset information of the second reference signal (eg, a time offset value or a set of time offset values).

[0542] In some embodiments, the identification information may include, but is not limited to, at least one of the following:

[0543] Trigger status information; for example, a status information in the aperiodic CSI reporting status information (CSI-AperiodicTriggerStateList) configured by the base station, or a CSI reporting ID (CSI-ReportConfigId), indicating activation of a CSI reporting associated with this status information, rather than all CSI reporting.

[0544] Resource or resource set information; for example: for beam management of multiple TRPs, one CSI report configuration (CSI-ReportConfig) is associated with two CSI-RS resource sets, that is, one CSI-ReportConfig is associated with two non-zero power CSI-RS resource sets (NZP-CSI-RS-ResourceSet). Each CSI-RS resource set corresponds to one TRP. The resource or resource set information here can be CSI-RS resource set indication information, such as using the identification information of the CSI-RS resource set to indicate the associated first CSI-RS resource set (i.e., TRP0), and can also indicate the associated second CSI-RS resource set (i.e., TRP1); or, the resource or resource set information can also be the ID of the CSI-RS resource set (such as NZP-CSI-RS-ResourceSetId), etc. The embodiments of the present disclosure are not limited to this.

[0545] Taking the beam management request information used to request the network device to perform beam management of TRP0 as an example, for example, two bits can be used to indicate the TRP for which beam management is requested, with each bit corresponding to a CSI-RS resource set (i.e., a TRP). For example, if these two bits are "10", it indicates the first CSI-RS resource set associated with the triggering CSI reporting (i.e., requesting beam management of TRP0).

[0546] In some embodiments, the transmission offset information of the second reference signal included in the beam management request information is similar to that in Example 1 and will not be repeated here.

[0547] Furthermore, taking the beam management request information used to request the network device to perform downlink beam management of TRP0 as an example, after the network device receives the beam management request information sent by the terminal, it can use the first format DCI (for example, the first format DCI is DCI format 0_1 / 0_2) to trigger the transmission of the second reference signal (such as non-periodic CSI-RS) and the reporting of the measurement results. In some embodiments, the first format DCI can use the same HARQ process number as the DCI of the PUSCH that schedules the transmission of the beam management request information, and the NDI is flipped to indicate a response to the terminal's beam management request, that is, to instruct the network device to confirm the downlink beam management of TRP0 requested by the terminal.

[0548] Optionally, other information fields in the DCI may further indicate activated CSI-RS resource set information (i.e., indicating an activated TRP) and / or indicate whether the terminal adopts group reporting of reference signal measurement results for different TRPs. For example, the terminal may report only the measurement result of the second reference signal of TRP0 (such as L1-RSRP) according to the instruction of the DCI, or adopt group reporting for TRP0 and TRP1 to report their corresponding reference signal measurement results (such as L1-RSRP), etc. The embodiments of the present disclosure are not limited to this.

[0549] Furthermore, the network device may also send third information to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, where the start information is used to start or activate the terminal's request for the network device to perform beam management (i.e., indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (i.e., indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling.

[0550] Example 6:

[0551] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0552] For example, in a multi-target object scenario (such as multiple TRPs), the terminal operates in a multi-TRP mode, and the multiple TRPs include TRP0 and TRP1. For example, if the terminal determines that the above-mentioned event 7 is satisfied (the RSRP of the source reference signal in the currently effective TCI state is less than the RSRP of the source reference signal in the first TCI state activated by the corresponding target object, or the BLER of the source reference signal in the currently effective TCI state is greater than the BLER of the source reference signal in the first TCI state activated by the corresponding target object), that is, a TRP-level event is triggered.

[0553] Similar to Example 2, when the measurement result satisfies the above-mentioned event 7, the terminal reports the corresponding measurement result. The measurement result may include second indication information and / or the number of groups of measurement results, and the second indication information is used to instruct the terminal to request reporting of the measurement result for each target object group.

[0554] For example: Similar to Example 2, the terminal directly reports the measurement results. At this time, if the terminal requests the use of group reporting through the second indication information, when the terminal reports the measurement results of the second reference signal (such as CSI-RS), the measurement results in each group represent the measurement results corresponding to the beams that the terminal can receive simultaneously, that is, the measurement results of the CSI-RS in the first CSI-RS resource set (i.e., TRP0) and the measurement results of the second reference signal (such as CSI-RS) in the second CSI-RS resource set (i.e., TRP1). If the terminal does not request the use of group reporting, when the terminal reports the measurement results of the second reference signal (such as CSI-RS), it only includes the measurement results of the second reference signal (such as CSI-RS) in a CSI-RS resource set for which beam management is requested. The specific implementation methods of other processes can be found in Example 2 and will not be repeated here.

[0555] Example 7:

[0556] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0557] Taking the example of a terminal requesting a network device to trigger uplink beam management through a beam management request message, the beam management request message includes: identification information of the third reference signal to be triggered, and / or transmission offset information of the third reference signal (such as a time offset value or a set of time offset values).

[0558] The identification information may be a trigger state (TriggerState) information of the SRS, for example, when the TriggerState corresponds to multiple SRS resource sets (i.e., multiple TRPs) at the same time. In the beam management request information requesting the network device to trigger uplink beam management, it may be further indicated which SRS resource set corresponds to the TriggerState, for example, by resource set identification information, or by sequential identification of multiple resource sets corresponding to the TriggerState (the first resource set, the second resource set, or the third resource set in the multiple resource sets corresponding to the TriggerState...).

[0559] In some embodiments, the transmission offset information of the third reference signal included in the beam management request information is similar to that in Example 1 and will not be repeated here.

[0560] Furthermore, the network device may also send third information to the terminal to activate or deactivate the terminal's request for the network device to perform beam management. For example, the third information includes: start information and / or termination information, where the start information is used to start or activate the terminal's request for the network device to perform beam management (i.e., indicating that the network device allows the terminal to request the network device to perform beam management). For example, the network device may instruct the terminal to allow it to request the network device to perform beam management by activating MAC CE signaling. The termination information is used to shut down or deactivate the terminal's request for the network device to perform beam management (i.e., indicating that the network device does not allow the terminal to request the network device to perform beam management, or instructs the terminal to stop requesting the network device to perform beam management). For example, the network device may instruct the terminal to stop or not allow the request for the network device to perform beam management by deactivating MAC CE signaling.

[0561] Example 8:

[0562] Based on protocol agreement or by network equipment (such as a base station), a beam management trigger event is configured for the terminal; the specific configuration of the beam management trigger event can be found in Example 1 and will not be repeated here.

[0563] Taking the example of a terminal requesting a network device to trigger uplink beam management and downlink beam management through beam management request information, the beam management request information includes both downlink reference signal related information and uplink reference signal related information. For example, the beam management request information includes at least one of the following:

[0564] identification information of the second reference signal to be triggered;

[0565] identification information of a third reference signal to be triggered;

[0566] Transmission offset information of the second reference signal (such as a time offset value or a set of time offset values);

[0567] Transmission offset information of the third reference signal (such as a time offset value or a set of time offset values).

[0568] Specifically, the identification information and the transmission offset information are similar to those in Example 1, or the indication of the transmission offset information may also be provided in the following manner:

[0569] The beam management request information includes one or more groups of offset values; wherein each group of offset values ​​includes an offset value of a downlink CSI-RS signal (i.e., the second reference signal) and an offset value of an uplink SRS signal (i.e., the third reference signal).

[0570] In some embodiments, the specific implementation of other processes of this embodiment can be found in Example 1 and will not be repeated here.

[0571] In an embodiment of the present disclosure, the terminal triggers a beam management request on its own according to a predefined or network-configured beam management trigger event, and indicates one or more of uplink beam management, downlink beam management, and beam management of at least one TRP in the reported beam management request. The embodiment of the present disclosure also supports directly triggering the transmission of a downlink or uplink reference signal through the beam management request information to start the beam management process of the terminal.
