[0001] The present application relates to the field of communication technology, and in particular to a communication method, apparatus, device, chip and storage medium. Background Art

[0002] In related technologies, network devices can obtain the optimal serving beam, thereby enabling terminal devices to switch serving beams through beam indication. During this process, the network device can configure the terminal device to measure and report the beam. However, frequent configuration of network devices can result in significant reporting and configuration overhead. Infrequent configuration of network devices can hinder timely beam measurement and reporting, delaying the terminal device's ability to switch serving beams.

[0003] In addition, only after a beam failure occurs does the terminal device have the opportunity to actively switch the service beam through the beam failure recovery mechanism, which obviously delays the switching of the service beam.

[0039] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0041] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device (NW) 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0042] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0043] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 located within the coverage area.

[0044] The network device 120 may be an evolved Node B (eNB or eNodeB) in an LTE system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0045] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0046] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.

[0047] The terminal device 110 can be used for device-to-device (D2D) communication.

[0048] FIG1 exemplarily shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0049] It should be noted that FIG1 is only an example of a system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this article.

[0050] It should be understood that the term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0051] It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0052] It should also be understood that the "correspondence" mentioned in the embodiments of the present application may indicate a direct or indirect correspondence between the two, or an association between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0053] It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0054] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0055] It should be noted that the "beam (pair)" in the embodiments of the present application can refer to a beam, including a transmit beam or a receive beam, or a beam pair, such as a transmit beam and a receive beam. The meaning of "beam (pair)" can apply to both uplink and downlink transmission. In the embodiments of the present application, a "beam (pair)" can also be referred to as a spatial filter.

[0056] Beam management mainly includes the terminal device measuring and reporting the beam, and the network device giving beam instructions based on the terminal device's report, so that the terminal device can perform beam switching.

[0057] It should be noted that beam measurement can measure periodic, semi-persistent and non-periodic downlink reference signals.

[0058] Exemplarily, the downlink reference signal may be a channel state information-reference signal (CSI-RS) or a synchronization signal block (Synchronization Signal and PBCH Block, SSB).

[0059] It should be noted that beam reporting is associated with uplink resources.

[0060] Exemplarily, beam reporting may be periodic reporting, for example, using physical uplink control channel (PUCCH) resources for beam reporting.

[0061] Exemplarily, beam reporting can be semi-continuous reporting, such as using PUCCH resources or physical uplink shared channel (PUSCH) resources for reporting, and semi-continuous reporting can be activated or deactivated using Media Access Control-Control Element (MAC CE).

[0062] Exemplarily, beam reporting may be non-periodic reporting, such as reporting using PUSCH resources, and non-periodic reporting may be triggered based on downlink control information (DCI) signaling sent by a network device.

[0063] It should be noted that, when the network device receives a beam report from the terminal device, the network device can provide beam instructions to the terminal device.

[0064] Exemplarily, the network device may indicate a transmission configuration indication (TCI) state to the terminal device, i.e., indicate a single transmit reception point (TRP); or, the network device may indicate a group of TCI States to the terminal device, i.e., indicate a group of multiple TRPs.

[0065] It should be understood that the TCI State can be the Legacy TCI in R15 or R16, or the unified TCI State defined in R17 and extended by R18. It should be understood that regardless of the type of TCI State, it can include a downlink reference signal (applicable to downlink and uplink transmission) or an uplink reference signal (applicable to uplink transmission). The QCL type of this reference signal is Type D, which can be used to indicate the Quasi Co-Location (QCL) relationship between different reference signals, that is, the beam relationship.

[0066] It should be noted that the beam management mechanism in related technologies is based on the configuration, activation, and / or indication of network devices. In other words, the terminal device's beam measurement and reporting must be based on the network device's configuration. This means that while the terminal device can detect issues such as downlink beam quality degradation, it cannot proactively and promptly report them.

[0067] In addition, only after a beam failure occurs does the terminal device have the opportunity to actively switch the service beam through the beam failure recovery mechanism, which obviously delays the time for the terminal device to switch the service beam.

[0068] The following is a brief description of the uplink control information (UCI) and PUCCH in NR.

[0069] UCI can be carried by PUCCH resources or PUSCH resources. UCI can include one or more of the following elements:

[0070] (1) Acknowledgment (ACK) / Negative Acknowledgment (NACK): used to confirm or not confirm the receipt of downlink data;

[0071] (2) Scheduling Request (SR): represents a request for uplink resources;

[0072] (3) Channel State Information (CSI): used to provide feedback on channel quality.

[0073] It should be noted that the above one or more elements may be combined and transmitted in a variety of ways and fed back to the network device through an uplink channel.

[0074] It should also be noted that, although both PUCCH resources and PUSCH resources can carry one or more elements in UCI, UCI containing SR is usually carried through PUCCH resources.

[0075] The 3rd Generation Partnership Project (3GPP) specifies five different PUCCH formats (formats 0, 1, 2, 3, and 4). Each format can be classified based on factors such as the allocation method of time-frequency resources (i.e., physical resources) and the number of bits carried.

[0076] The number of UCI bits carried by the time-frequency resources occupied by PUCCHs of formats 0 and 1 is less than or equal to 2, while the number of UCI bits carried by the time-frequency resources occupied by PUCCHs of formats 2, 3, and 4 is greater than 2.

[0077] Among them, PUCCH formats 0 and 2 can be called short PUCCH, and the length of short PUCCH is 1 to 2 Orthogonal Frequency Division Multiplexing (OFDM) symbols; PUCCH formats 1, 3, and 4 can be called long PUCCH, and the length of long PUCCH can reach 4 to 14 OFDM symbols.

[0078] It should be noted that PUCCH resources may include PUCCH resource sets (Resource Sets) and one or more PUCCH resources in each PUCCH resource set. Network equipment can typically configure one or more PUCCH resource sets and one or more PUCCH resources in each resource set for a terminal device. Which PUCCH resource set the terminal device uses for transmission is mainly based on the number of UCI bits to be carried, and which PUCCH resource (resource ID) to use in the selected PUCCH resource set is determined by DCI 1_x.

[0079] It should also be noted that the number of UCI bits carried by the time-frequency resources occupied by the short PUCCH is at most 2, which is selected based on the sequence; on the time-frequency resources occupied by the short PUCCH where the number of UCI bits carried exceeds 2, the UCI and the demodulation reference signal (DMRS) need to be frequency multiplexed.

[0080] It should also be noted that the UCI carried by the time-frequency resources occupied by the long PUCCH needs to be time-multiplexed with the DMRS. The long PUCCH supports frequency hopping, as does the short PUCCH, which has a duration of two OFDM symbols. The long PUCCH can be repeated in multiple time slots.

[0081] It should be understood that the payload of some PUCCH resources is relatively small, for example, not exceeding 2 bits; the payload of some PUCCH resources is relatively large, for example, they can carry CSI reporting, including reporting of beam management events.

[0082] In the related art, the network device can obtain the best service beam, so that the terminal device can switch the service beam through the beam indication. On the one hand, if the network device configures (such as through signaling indication or activation) frequent periodic or semi-continuous beam reporting (for example, the best N beams and their corresponding Layer 1 Reference Signal Receiving Power (Layer 1-Reference Signal Receiving Power, L1-RSRP)), or triggers frequent non-periodic beam reporting, it will result in large reporting overhead and configuration overhead; on the other hand, if the beam reporting configured by the network device is less frequent, the beam reporting of the terminal device may be outdated, making the network device unable to obtain the best or preferred service beam, thereby delaying the terminal device's switching of the service beam and resulting in performance degradation.

[0083] In addition, only after a beam failure occurs does the terminal device have the opportunity to actively switch the service beam through the beam failure recovery mechanism, which obviously delays the switching of the service beam.

[0084] Based on this, an embodiment of the present application provides a communication method, in which, when a first event meets a preset condition, the terminal device can send a first event to the network device on a first PUCCH resource or a first PUSCH resource, and the first event is used by the network device to determine the first service space filter for the first time period. In this way, after the terminal device determines that the first event meets the preset condition, it can carry the report of the first event through the first PUCCH resource or the first PUSCH resource. In this way, the terminal device can actively report the first event, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service space filter.

[0085] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0086] FIG2 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG2 , the method may include the following steps.

[0087] S210. When the first event meets a preset condition, the terminal device sends the first event to the network device on the first PUCCH resource or the first PUSCH resource. The first event is used by the network device to determine the first service space filter for the first time period.

[0088] Accordingly, the network device may receive the first event sent by the terminal device on the first PUCCH resource or the first PUSCH resource.

[0089] Exemplarily, the PUSCH resources may be the time-frequency resources occupied by the PUSCH scheduled by the uplink DCI, or the time-frequency resources occupied by the Type 1 configured grant (Configured Grant, CG)-PUSCH configured by the radio resource control (RRC), or the time-frequency resources occupied by the Type 2 CG-PUSCH configured by RRC or activated by DCI. This embodiment of the present application is not limited to this.

[0090] Exemplarily, the first event may be a spatial filter (ie, beam) management event.

[0091] It should be noted that the terminal device sending the first event to the network device can be understood as the terminal device sending a spatial filter management event to the network device. In other words, the terminal device reports (ie sends) the spatial filter to the network device.

[0092] It should also be noted that the first time period may be a period after the current moment. In other words, the first time period may be a future time period. The first service space filter may be a service space filter used by the terminal device for a period after the current moment.

[0093] It should also be noted that, since the terminal device can more accurately and promptly determine whether the first event satisfies the preset conditions (such as whether the link quality of the spatial filter has changed), the spatial filter reporting process initiated by the terminal device (i.e., the terminal device sends the first event) can bring about more timely spatial filter reporting and reduce reporting overhead and configuration overhead. For example, when the terminal device determines that the quality of the service spatial filter at the current moment has deteriorated, the terminal device can actively trigger the spatial filter reporting (i.e., actively send the first event) without the need for the configuration of the network device (such as the network device frequently triggering the spatial filter reporting), thereby enabling more timely switching of the service spatial filter.

[0094] It should be understood that when the first event does not meet the preset conditions, the terminal device may not send the first event to the network device, and the network device does not need to be configured, thereby further saving reporting overhead and configuration overhead.

[0095] In the related art, there is a certain degree of randomness in the sending of the first event by the terminal device to the network device; however, in an embodiment of the present application, the terminal device can send the first event to the network device when it is determined that the first event meets the preset conditions, so that the terminal device can subsequently switch the service space filter in a timely manner.

[0096] In some embodiments, the method may further include: the network device may send a TCI state to the terminal device, where the TCI state is related to the first service spatial filter.

[0097] Accordingly, the terminal device can receive the TCI status sent by the network device.

[0098] It should be noted that the TCI state can be the Legacy TCI in R15 or R16, or the unified TCI state defined in R17 and extended in R18, or other TCI states, which is not limited in the embodiments of the present application.

[0099] It should also be noted that the TCI state may include a reference signal. After the terminal device receives the TCI state, it can determine the first service space filter associated with the reference signal based on the reference signal in the TCI state, so that it can switch to the first service space filter.

[0100] Exemplarily, the reference signal may be a CSI-RS or an SSB.

[0101] Exemplarily, when the terminal device reports the spatial filter (i.e., the terminal device sends the first event), it can report the index of the reference signal resource (such as CSI-RS resource, such as SSB resource) corresponding to the candidate spatial filter. The index of the reference signal resource can be associated with a unified TCI state, and the unified TCI state can include the reference signal (implemented through the RRC configuration of the network device). After the terminal device completes the spatial filter reporting, the terminal device expects beam indication information from the network device. The network device can indicate the unified TCI state to the terminal device through DCI signaling or MAC CE signaling.

[0102] When the reference signal is an uplink reference signal, the unified TCI state can be associated with an uplink timing advance group (TAG), which corresponds to a timing advance (TA) value. Furthermore, the unified TCI state can be associated with a set of uplink power control (also known as power control) parameters, which can include the open-loop receive power target value P0, the partial path loss compensation factor Alpha closed-loop power control index (CLI), and the path loss reference signal (PL RS).

[0103] When the reference signal is a downlink reference signal, the index of the reported reference signal resource (such as the Channel State Information-Reference Signal Resource Indicator (CRI)) can be associated with a set of CSI, which includes information such as the Precoding Matrix Indicator (PMI), Rank Indicator (RI), and Channel Quality Indicator (CQI). In other words, the index of the reported reference signal resource can be associated with CSI on one or more spatial filters.

[0104] Through this method, the network device can send the TCI status to the terminal device, so that after the terminal device receives the TCI status, it can determine the first service space filter related to the TCI status and then switch to the first service space filter in time.

[0105] In some embodiments, the first event may include one or more of the following:

[0106] an index of a reference signal resource corresponding to the second serving spatial filter;

[0107] link quality of the reference signal resource corresponding to the second serving spatial filter;

[0108] The index of the reference signal resource corresponding to the candidate spatial filter;

[0109] link quality of the reference signal resource corresponding to the candidate spatial filter;

[0110] a fluctuation range of the link quality of the reference signal resource corresponding to the second serving spatial filter;

[0111] Interference strength of the candidate spatial filter on the second serving spatial filter;

[0112] The second service space filter is a service space filter for a third time period, and an end time of the third time period is earlier than a start time of the first time period.

[0113] Exemplarily, the candidate spatial filter and the serving spatial filter (such as the second serving spatial filter) may each correspond to a reference signal resource.

[0114] It should be noted that the third time period may be the current moment and / or a period of time before the current moment. The second service space filter may be a service space filter used by the terminal device at the current moment and / or a period of time before the current moment.

[0115] Furthermore, the second service spatial filter and the first service spatial filter may be the same spatial filter or different spatial filters, which is not limited in this embodiment of the present application.

[0116] It should be noted that link quality can be measured using physical layer indicators. Link quality may include Reference Signal Receiving Power (RSRP) (such as L1-RSRP), Signal to Interference plus Noise Ratio (SINR) (such as L1-SINR), Received Signal Strength Indicator (RSSI) (such as L1-RSSI), Reference Signal Receiving Quality (RSRQ) (such as L1-RSRQ), and Physical Downlink Control Channel (PDCCH) Block Error Rate (BLER).

[0117] Furthermore, link quality can also serve as input and output for artificial intelligence (AI) / machine learning (ML) models.

[0118] For example, for PDCCH BLER, the terminal device can convert L1-SINR into PDCCH BLER according to the definition in the protocol. Generally, when PDCCH BLER is higher than 1%, it can be considered that the link quality is poor and needs to be adjusted.

[0119] It should also be noted that the candidate spatial filters belong to the serving cell and / or the candidate cell.

[0120] It should be understood that in the embodiments of the present application, the serving spatial filter (such as the first serving spatial filter and the second serving spatial filter) belongs to the serving cell. The candidate spatial filter may belong to the serving cell or the candidate cell, and the embodiments of the present application do not limit this.

[0121] Exemplarily, the index of the candidate cell may be represented by a physical cell identity (PCI).

[0122] Figure 3 is a schematic diagram of a serving spatial filter and a candidate spatial filter scenario provided by an embodiment of the present application. As shown in Figure 3, a serving cell may have a serving spatial filter and a candidate spatial filter; a candidate cell may have a candidate spatial filter.

[0123] It should be noted that NR supports the inter-cell beam management mechanism in R17, that is, the candidate spatial filter of the candidate cell can also be switched to the service spatial filter. That is to say, when the terminal device switches the service spatial filter, it can switch the candidate spatial filter in the serving cell to the service spatial filter, or it can switch the candidate spatial filter in the candidate cell to the service spatial filter. This embodiment of the application is not limited to this.

[0124] Through this method, the terminal device can actively report the first event. When the second service spatial filter and the first service spatial filter are the same spatial filter, the reporting overhead and configuration overhead can be reduced; when the second service spatial filter and the first service spatial filter are different spatial filters, the reporting overhead and configuration overhead can be reduced without delaying the terminal device's switching of the service spatial filter (from the second service spatial filter to the first service spatial filter).

[0125] In some embodiments, the fluctuation range of the link quality of the reference signal resource corresponding to the second service spatial filter is: the number of times the link quality of the reference signal resource corresponding to the second service spatial filter fluctuates above or below the fifth threshold within the fourth time period.

[0126] The end time of the fourth time period is earlier than the start time of the first time period.

[0127] It should be noted that the fourth time period may be the current moment and / or a period of time before the current moment.

[0128] It should also be noted that the fourth time period and the third time period can be the same time period, or the fourth time period and the third time period can be different time periods, which is not limited in the embodiment of the present application.

[0129] It should also be noted that the number of times the link quality fluctuates upward above the fifth threshold can be understood as the number of times the link quality crosses the fifth threshold from bottom to top; the number of times the link quality fluctuates downward above the fifth threshold can be understood as the number of times the link quality crosses the fifth threshold from top to bottom.

[0130] It should be understood that the fifth threshold value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0131] Figure 4 is a schematic diagram of a link quality fluctuation scenario provided by an embodiment of the present application. As shown in Figure 4, during the fourth time period, the link quality of the reference signal resource corresponding to the second serving spatial filter fluctuates upward above the fifth threshold twice and downward above the fifth threshold three times. Therefore, the link quality of the reference signal resource corresponding to the second serving spatial filter fluctuates within a range of two or three times.

[0132] In some embodiments, the fluctuation range of the link quality of the reference signal resource corresponding to the second serving spatial filter is:

[0133] The duration of time during which the link quality of the reference signal resource corresponding to the second serving spatial filter is higher or lower than the sixth threshold within the fifth time period; or

[0134] a ratio of a duration in which the link quality of the reference signal resource corresponding to the second serving spatial filter is higher or lower than a sixth threshold to a fifth time period.

[0135] The end time of the fifth time period is earlier than the start time of the first time period.

[0136] It should be noted that the fifth time period may be the current moment and / or a period of time before the current moment.

[0137] It should also be noted that the fifth time period can be the same time period as the third time period and the fourth time period, or the fifth time period can be different time periods from the third time period and the fourth time period, and this embodiment of the present application does not limit this.

[0138] It should be understood that the sixth threshold value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0139] Figure 5 is a second schematic diagram of a link quality fluctuation scenario provided by an embodiment of the present application. As shown in Figure 5, during the fifth time period, the link quality of the reference signal resource corresponding to the second serving spatial filter is lower than the sixth threshold for a duration of T1 + T2. Therefore, the fluctuation range of the link quality of the reference signal resource corresponding to the second serving spatial filter is: T1 + T2 or (T1 + T2) / fifth time period.

[0140] It should be understood that the exemplary description of the link quality of the reference signal resource corresponding to the second service spatial filter when it is higher than the sixth threshold is similar to the exemplary description when it is lower than the sixth threshold, and will not be repeated here.

[0141] In some embodiments, the preset conditions may include one or more of the following:

[0142] The link quality of the reference signal resource corresponding to the second serving spatial filter is greater than a second threshold;

[0143] The link quality of the reference signal resource corresponding to the second serving spatial filter is less than or equal to a second threshold;

[0144] The link quality of the reference signal resource corresponding to the candidate spatial filter is greater than the link quality of the reference signal resource corresponding to the second serving spatial filter plus the offset value;

[0145] The link quality of the reference signal resource corresponding to the candidate spatial filter is greater than a third threshold;

[0146] The link quality of the reference signal resource corresponding to the second serving spatial filter is less than or equal to the second threshold, and the link quality of the reference signal resource corresponding to the candidate spatial filter is greater than a third threshold;

[0147] The fluctuation range of the link quality of the reference signal resource corresponding to the second serving spatial filter exceeds a preset range;

[0148] The interference intensity of the candidate spatial filter on the second serving spatial filter is greater than a fourth threshold;

[0149] The second service space filter is a service space filter for a third time period, and an end time of the third time period is earlier than a start time of the first time period.

[0150] It should be understood that the second threshold value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0151] It should also be understood that the third threshold value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0152] It should also be understood that the fourth threshold may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0153] It should also be understood that the offset value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0154] It should be noted that, when the preset condition includes: the link quality of the reference signal resource corresponding to the second serving spatial filter is greater than the second threshold, the second serving spatial filter is the same as the first serving spatial filter.

[0155] That is to say, when the link quality of the reference signal resource corresponding to the second service spatial filter is greater than the second threshold, the terminal device does not need to switch the second service spatial filter.

[0156] Exemplarily, when the link quality of the reference signal resource corresponding to the second serving spatial filter is greater than a second threshold, it indicates that the first event meets the preset condition, and reporting of the first event can be triggered. After receiving the first event, the network device can be informed that the terminal device does not need to switch the second serving spatial filter, and thus does not need to perform a spatial filter indication (such as not sending the TCI status), thereby reducing reporting overhead and configuration overhead.

[0157] Exemplarily, when the link quality of the reference signal resource corresponding to the second service spatial filter is less than or equal to the second threshold, it indicates that the first event meets the preset conditions, and the reporting of the first event can be triggered at this time. After receiving the first event, the network device can be informed that the terminal device needs to switch the second service spatial filter, so that the spatial filter indication (such as sending the TCI status) can be performed in a timely manner subsequently, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service spatial filter (from the second service spatial filter to the first service spatial filter).

[0158] Exemplarily, when the link quality of the reference signal resource corresponding to the candidate spatial filter is greater than the link quality of the reference signal resource corresponding to the second service spatial filter plus the offset value, it indicates that the first event meets the preset conditions, and the reporting of the first event can be triggered at this time. After receiving the first event, the network device can be informed that the terminal device needs to switch the second service spatial filter, so that the spatial filter indication can be made in time (such as sending the TCI status) subsequently, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service spatial filter (from the second service spatial filter to the first service spatial filter).

[0159] It should be noted that the fluctuation range of the link quality of the reference signal resource corresponding to the second serving spatial filter exceeds the preset range, which can be understood as:

[0160] In the fourth time period, the link quality of the reference signal resource corresponding to the second serving spatial filter fluctuates above or below the fifth threshold more than a preset number of times; or

[0161] In the fifth time period, the link quality of the reference signal resource corresponding to the second serving spatial filter is higher or lower than the sixth threshold for a duration exceeding a preset time; or,

[0162] In the fifth time period, the ratio of the duration of the link quality of the reference signal resource corresponding to the second serving spatial filter being higher or lower than the sixth threshold to the duration of the fifth time period exceeds a preset ratio.

[0163] Exemplarily, as shown in Figure 4, within the fourth time period, the link quality fluctuates downward below the fifth threshold three times. Assuming that the preset number of times the link quality fluctuates downward below the fifth threshold is two times, it means that the fluctuation range of the link quality of the reference signal resource corresponding to the second service space filter exceeds the preset range.

[0164] Exemplarily, as shown in Figure 5, in the fifth time period, the duration of the link quality being lower than the sixth threshold is T1+T2. Assuming that the preset time of the link quality being lower than the sixth threshold is less than T1+T2, it means that the fluctuation range of the link quality of the reference signal resource corresponding to the second service space filter exceeds the preset range.

[0165] Through this method, when the first event meets the preset conditions, the terminal device can actively report the first event. When the second service spatial filter and the first service spatial filter are the same spatial filter, the reporting overhead and configuration overhead can be reduced; when the second service spatial filter and the first service spatial filter are different spatial filters, the reporting overhead and configuration overhead can be reduced without delaying the terminal device's switching of the service spatial filter (from the second service spatial filter to the first service spatial filter).

[0166] An embodiment of the present application provides a communication method, in which, when a first event meets a preset condition, a terminal device can send a first event to a network device on a first PUCCH resource or a first PUSCH resource, and the first event is used by the network device to determine a first service space filter for a first time period. In this way, after determining that the first event meets the preset condition, the terminal device can carry the report of the first event through the first PUCCH resource or the first PUSCH resource. In this way, the terminal device can actively report the first event, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service space filter.

[0167] In an embodiment of the present application, before sending the first event, the terminal device needs to obtain the first PUSCH resource or the first PUCCH resource to carry the report of the first event. Assuming that the terminal device does not have a pre-allocated first PUSCH resource or the first PUCCH resource within a certain time window, the network device needs to accurately indicate the first PUSCH resource or the first PUCCH resource to carry the transmission of the first event. The network device can indicate the first PUSCH resource or the first PUCCH resource based on one or more of the following methods.

[0168] Method #A: The terminal device can request a first PUSCH resource based on the first SR, thereby carrying the report of the first event based on the first PUSCH resource.

[0169] FIG6 is a schematic diagram of a detailed flow chart of a communication method provided in an embodiment of the present application. As shown in FIG6 , the detailed flow chart may include the following steps:

[0170] S610. On a second PUCCH resource associated with a first SR opportunity, the terminal device sends a first SR to the network device, where the first SR is used to request a first PUSCH resource.

[0171] S620. The network device sends first information to the terminal device, where the first information is used to indicate a first PUSCH resource.

[0172] S630: On the first PUSCH resource, the terminal device sends a first event to the network device.

[0173] The first event is used by the network device to determine a first service space filter in a first time period.

[0174] It should be noted that the terminal device sends the first SR to the network device after the terminal device determines that the first event meets the preset conditions, or before the terminal device determines that the first event meets the preset conditions. This embodiment of the present application does not limit this.

[0175] It should also be noted that the second PUCCH format usually has a smaller payload (eg, no more than 2 bits), and thus the second PUCCH resource cannot be used to carry the report of the first event.

[0176] It should also be noted that, when the terminal device determines that the first event meets the preset condition, the terminal device sends the first event to the network device on the first PUSCH resource. In other words, when the terminal device determines that the first event meets the preset condition, it executes S630.

[0177] In related technologies, when a terminal device has uplink transmission requirements, it can send an SR to the network device to request PUSCH resources. However, the content carried by the PUSCH resources includes higher-layer data or MAC CE of the Media Access Control (MAC) layer, and does not involve the carrying of the first event.

[0178] In the embodiment of the present application, the first SR may be used to request a first PUSCH resource, and the first PUSCH resource may be used to carry a report of a first event. It should be understood that the first SR may have the following two possible implementations.

[0179] In one possible implementation, the first SR may be a regular SR.

[0180] The first SR may include not only 1 bit of information, but also the type of information carried by the requested first PUSCH resource (such as the first information type or the second information type). In other words, the first SR may include 2 bits or more of information.

[0181] Exemplarily, the 1-bit information being "0" indicates that no scheduling request is made (ie, a negative scheduling request), and the 1-bit information being "1" indicates that a scheduling request is made (ie, a positive scheduling request).

[0182] In some embodiments, the first SR may include three code points, where:

[0183] The first code point indicates that no scheduling request is made;

[0184] The second code point represents a first information type carried by the first PUSCH resource, where the first information type includes higher layer data or a MAC CE of a MAC layer;

[0185] The third code point represents a second information type carried by the first PUSCH resource, where the second information type includes a first event.

[0186] It should be noted that the first SR may include 2 bits of information: the first code point may be "00", the second code point may be "01", and the third code point may be "10". In addition, the first SR may also include a fourth code point "11", which may be used as a reserved bit.

[0187] Through this method, when the first SR is a regular SR, the first SR may include the type of information carried by the requested first PUSCH resource, so that the terminal device can request the first PUSCH resource from the network device through the first SR, so as to subsequently use the first PUSCH resource to carry the report of the first event.

[0188] In another possible implementation, the first SR may be a special SR.

[0189] It should be noted that the terminal device can send a special SR (ie, the first SR) to the network device on the second PUCCH resource associated with the first SR opportunity.

[0190] Furthermore, the particularity of the first SR is that the first SR is specifically used to request a first PUSCH resource capable of carrying a first event.

[0191] In some embodiments, the first SR may be configured through RRC signaling.

[0192] For example, the first SR may be configured by the network device through RRC signaling and is different from the SR used to request PUSCH to carry higher layer data or MAC CE. The network device may configure a special SR (i.e., the first SR) that can request the first PUSCH resource for carrying the first event.

[0193] In some embodiments, the first information may be carried via DCI signaling and / or MAC CE signaling.

[0194] Exemplarily, the network device may allocate the first PUSCH resource to the terminal device through DCI signaling and / or MAC CE signaling.

[0195] Exemplarily, the network device may activate a first PUSCH resource dedicated to the terminal device through DCI signaling instructions and / or MAC CE signaling, and the terminal device may use the dedicated first PUSCH resource to carry the report of the first event.

[0196] Exemplarily, the network device may activate the common first PUSCH resource through DCI signaling indication and / or MAC CE signaling, and the terminal device may use the common first PUSCH resource to carry the report of the first event.

[0197] It should be noted that when a terminal device uses the first SR to request the first PUSCH resource, the terminal device usually needs to wait for the periodic first SR opportunity. If the period of the first SR opportunity is configured too long, the first event may not be reported in a timely manner; if the period of the first SR opportunity is configured too short, a certain amount of second PUCCH resources need to be reserved. Based on this, when configuring the first SR, the network device should try to avoid the period of the first SR opportunity being too long or too short, so that the first event can be reported in a timely manner and the occupancy of excessive second PUCCH resources is reduced.

[0198] It should also be noted that the network device may decide whether to allocate PUSCH resources to a terminal device based on the importance of different SRs. The reporting of the first event often involves changes in link quality and may even involve beam failure events. Therefore, when the first SR is used to request the first PUSCH resource, the network device may consider the first PUSCH resource requested by the first SR to be more important after receiving the first SR.

[0199] Through method #A, the terminal device can send a first SR to the network device, so that the network device knows that the first PUSCH resource requested by the first SR is more important (that is, the first PUSCH resource indicated by the network device can carry the first event), so that the first PUSCH resource can be indicated to the terminal device in a timely manner. The terminal device can use the first PUSCH resource to carry the report of the first event, thereby reducing the reporting overhead and configuration overhead without delaying the terminal device's switching of the serving space filter.

[0200] Method #B: The terminal device can request the first PUCCH resource based on the second SR, thereby carrying the report of the first event based on the first PUCCH resource.

[0201] FIG7 is a second detailed flow diagram of a communication method provided in an embodiment of the present application. As shown in FIG7 , the detailed flow may include the following steps:

[0202] S710. On a third PUCCH resource associated with a second SR opportunity, the terminal device sends a second SR to the network device, where the second SR is used to request the first PUCCH resource.

[0203] S720. The network device sends second information to the terminal device, where the second information is used to indicate the first PUCCH resource.

[0204] S730. On the first PUCCH resource, the terminal device sends a first event to the network device.

[0205] The first event is used by the network device to determine a first service space filter in a first time period.

[0206] It should be noted that the terminal device sends the second SR to the network device after the terminal device determines that the first event meets the preset conditions, or before the terminal device determines that the first event meets the preset conditions. This embodiment of the present application does not limit this.

[0207] It should also be noted that the third PUCCH format usually has a small payload (such as no more than 2 bits), so the third PUCCH resource cannot be used to carry the report of the first event; the first PUCCH resource requested by the second SR has a large payload (such as more than 2 bits), so the first PUCCH resource can be used to carry the report of the first event.

[0208] Furthermore, when the second SR opportunity arrives, the terminal device can use the third PUCCH resource associated with the second SR opportunity to request the first PUCCH resource. Since the payload of the third PUCCH resource is insufficient to carry the report of the first event, the terminal device can send a second SR to the network device through the third PUCCH resource, thereby requesting the first PUCCH resource to carry the report of the first event.

[0209] It should be noted that, when the terminal device determines that the first event meets the preset condition, the terminal device sends the first event to the network device on the first PUCCH resource. In other words, when the terminal device determines that the first event meets the preset condition, it executes S730.

[0210] In related technologies, when a terminal device has an uplink transmission requirement, it can send an SR to a network device to request a PUSCH resource. The content carried by the PUSCH resource includes high-layer data or MAC CE of the MAC layer, and does not involve the carrying of the first event.

[0211] In the embodiment of the present application, the second SR may be used to request a first PUCCH resource, and the first PUCCH resource may be used to carry a report of the first event.

[0212] In some embodiments, the second SR may be a special SR.

[0213] It should be noted that the terminal device can send a special SR (ie, the second SR) to the network device on the third PUCCH resource associated with the second SR opportunity.

[0214] Furthermore, the special feature of the second SR is that the second SR can be specifically used to request a first PUCCH resource that carries a first event.

[0215] In some embodiments, the second SR may be configured through RRC signaling.

[0216] For example, the second SR may be configured by the network device through RRC signaling and is different from the SR used to request PUSCH to carry higher layer data or MAC CE. The network device may configure a special SR (i.e., the second SR) that can be used to request the first PUCCH resource carrying the first event.

[0217] In some embodiments, the second information may be carried via DCI signaling and / or MAC CE signaling.

[0218] Exemplarily, the network device may allocate the first PUCCH resource to the terminal device through DCI signaling and / or MAC CE signaling.

[0219] Exemplarily, the network device may activate a first PUCCH resource dedicated to the terminal device through DCI signaling instructions and / or MAC CE signaling, and the terminal device may use the dedicated first PUCCH resource to carry the report of the first event.

[0220] Exemplarily, the network device may activate the common first PUCCH resource through DCI signaling indication and / or MAC CE signaling, and the terminal device may use the common first PUCCH resource to carry the report of the first event.

[0221] It should be noted that when a terminal device uses the second SR to request the first PUCCH resource, the terminal device usually needs to wait for the periodic second SR opportunity. If the period of the second SR opportunity is configured too long, the first event may not be reported in a timely manner; if the period of the second SR opportunity is configured too short, a certain amount of third PUCCH resources must be reserved. Based on this, when configuring the second SR, the network device should try to avoid the second SR opportunity period being too long or too short, so that the first event can be reported in a timely manner and the excessive occupation of the third PUCCH resource is reduced.

[0222] It should also be noted that the reporting of the first event often involves changes in link quality and may even cause a beam failure event. Therefore, when the second SR is used to request the first PUCCH resource, after the network device receives the second SR, it can be considered that the first PUCCH resource requested by the second SR is more important.

[0223] Through method #B, the terminal device can send a second SR to the network device, so that the network device knows that the first PUCCH resource requested by the second SR is more important (that is, the first PUCCH resource indicated by the network device can carry the first event), so that the first PUCCH resource can be indicated to the terminal device in a timely manner. The terminal device can use the first PUCCH resource to carry the report of the first event, thereby reducing reporting overhead and configuration overhead without delaying the terminal device's switching of the serving space filter.

[0224] In addition, compared with PUSCH resources, the first PUCCH resource can occupy a small amount of uplink time-frequency resources. When the network device indicates the first PUCCH resource to the terminal device through the second information, the number of bits required for the second information is also small.

[0225] Method #C: The network device can pre-configure the first PUCCH resource or the first PUSCH resource.

[0226] In some embodiments, the first PUCCH resource or the first PUSCH resource is pre-configured.

[0227] Furthermore, the first PUCCH resource or the first PUSCH resource is a public resource or a dedicated resource.

[0228] Exemplarily, the terminal device may carry the report of the first event based on the pre-configured public first PUCCH resource or the first PUSCH resource. The configuration feature of the public first PUCCH resource or the first PUSCH resource is a common attribute. That is, the public first PUCCH resource or the first PUSCH resource is not exclusive to a certain terminal device, but multiple terminal devices can send information on the same first PUCCH resource or the first PUSCH resource in a multiplexing manner.

[0229] Exemplarily, the network device may pre-configure a dedicated first PUCCH resource or a first PUSCH resource for the terminal device to carry the report of the first event.

[0230] The first event is used by the network device to determine a first service space filter in a first time period.

[0231] It should be understood that when there are multiple terminal devices, if the first PUCCH resources or first PUSCH resources exclusive to the multiple terminal devices do not support multi-user multiplexing, the network device can avoid mutual interference between the multiple terminal devices by configuring different periods and / or offsets.

[0232] It should also be understood that when there are multiple terminal devices and the network device configures exclusive first PUCCH resources or first PUSCH resources for multiple terminal devices, there is no need to share resources between the multiple terminal devices, and each terminal device has exclusive resources.

[0233] Exemplarily, the network device may pre-configure the first PUCCH resource or the first PUSCH resource through RRC signaling. For example, the network device may pre-configure multiple periodic, semi-persistent, or aperiodic first PUCCH resources through RRC signaling; for another example, the network device may configure one or more Type 1 or Type 2 CG-PUSCH resources through RRC signaling.

[0234] In some embodiments, when the network device pre-configures the first PUCCH resource or the first PUSCH resource, and the number of the first PUCCH resources or the first PUSCH resources is multiple, the network device can indicate the first PUCCH resource or the first PUSCH resource used for uplink transmission within a period of time, so that the terminal device can carry the report of the first event based on the first PUCCH resource or the first PUSCH resource used for uplink transmission.

[0235] FIG8 is a third detailed flow diagram of a communication method provided in an embodiment of the present application. As shown in FIG8 , the detailed flow may include the following steps:

[0236] S810. The network device preconfigures a first PUCCH resource or a first PUSCH resource;

[0237] S820. The network device sends third information to the terminal device, where the third information is used to indicate one or more first PUCCH resources or first PUSCH resources that can be used for uplink transmission in the second time period.

[0238] S830. The terminal device sends a first event to the network device on one or more first PUCCH resources or first PUSCH resources used for uplink transmission.

[0239] The start time of the second time period is earlier than the start time of the first time period.

[0240] Exemplarily, the second time period may be a period of time after the current moment.

[0241] It should be noted that, when the terminal device determines that the first event meets the preset conditions, it sends the first event to the network device on one or more first PUCCH resources or first PUSCH resources used for uplink transmission. In other words, when the terminal device determines that the first event meets the preset conditions, it executes S830.

[0242] For example, assuming that there are 8 time slots in the second time period, the network device pre-configures a potentially usable first PUCCH resource or first PUSCH resource for each time slot, and the network device can indicate the first PUCCH resource or first PUSCH resource that can be used for uplink transmission in the second time period, and the first PUCCH resource or first PUSCH resource that cannot be used for uplink transmission through the third information. For example, the network device indicates a bit map {00110100} through the third information, so that the terminal device can know that in the second time period, the first PUCCH resource or first PUSCH resource on the 3rd, 4th and 6th time slots can be used for uplink transmission, and the first PUCCH resource or first PUSCH resource on the 1st, 2nd, 5th, 7th and 8th time slots cannot be used for uplink transmission, thereby avoiding interference with the uplink transmission of other terminal devices.

[0243] In some embodiments, the third information may be carried via DCI signaling and / or MAC CE signaling.

[0244] Exemplarily, when the third information is carried by DCI signaling, the third information may be used to indicate one or more first PUCCH resources that can be used for uplink transmission in the second time period. That is, the network device may indicate one or more first PUCCH resources that can be used for uplink transmission in the second time period through DCI signaling. The indication method of the DCI signaling may include:

[0245] (1) For a multicast DCI for multiple terminal devices, one or more terminal devices in the group can use the first PUCCH resource indicated by the DCI;

[0246] (2) For the broadcast DCI of all terminal devices, all terminal devices can use the first PUCCH resource indicated by the DCI;

[0247] (3) For unicast DCI of a single terminal device, the terminal device that receives the dedicated DCI can use the indicated first PUCCH resource.

[0248] It should be understood that, among the one or more first PUCCH resources indicated by the third information, some of the first PUCCH resources have a small payload (e.g., no more than 2 bits) and cannot carry the report of the first event; some of the first PUCCH resources have a large payload (e.g., more than 2 bits) and can carry the report of the first event. After receiving the third information, the terminal device can use the first PUCCH resource with a larger payload among the one or more first PUCCH resources indicated by the third information to carry the report of the first event.

[0249] Exemplarily, when the third information is carried by DCI signaling, the third information may be used to indicate one or more first PUSCH resources that can be used for uplink transmission in the second time period. That is, the network device may indicate one or more first PUSCH resources that can be used for uplink transmission in the second time period through DCI signaling. The indication method of the DCI signaling may include:

[0250] (1) For a multicast DCI for multiple terminal devices, one or more terminal devices in the group can use the first PUSCH resource indicated by the DCI;

[0251] (2) For the broadcast DCI of all terminal devices, all terminal devices can use the first PUSCH resource indicated by the DCI;

[0252] (3) For unicast DCI of a single terminal device, the terminal device that receives the dedicated DCI can use the indicated first PUSCH resource.

[0253] It should be understood that the one or more first PUSCH resources indicated by the third information have sufficient load capacity to carry the report of the first event.

[0254] Exemplarily, when the third information is carried by MAC CE signaling, the third information may be used to indicate one or more first PUSCH resources or first PUCCH resources that can be used for uplink transmission in the second time period. That is, the network device may indicate one or more first PUSCH resources or first PUCCH resources that can be used for uplink transmission in the second time period through MAC CE signaling. The indication method of the MAC CE signaling may include:

[0255] For a unicast MAC CE of a certain terminal device, the terminal device that receives the dedicated MAC CE can use the indicated first PUSCH resource or first PUCCH resource.

[0256] It should be understood that MAC CE is a terminal device-specific signaling and does not have broadcast and multicast features. Therefore, the instruction of this MAC CE is only for a single terminal device.

[0257] Through this method, for the pre-configured first PUCCH resource or first PUSCH resource, the network device can more flexibly indicate one or more first PUCCH resources or first PUSCH resources that can be used for uplink transmission, while also avoiding the overhead of the terminal device requesting the first PUCCH resource or first PUSCH resource.

[0258] In some embodiments, the characteristics of the first PUCCH resource or the first PUSCH resource may include one or more of the following:

[0259] A load of the first PUCCH resource or the first PUSCH resource is greater than a first threshold;

[0260] The first PUCCH resource or the first PUSCH resource is configured in a broadcast mode, a multicast mode, or a unicast mode;

[0261] The first PUCCH resource is configured in one or more PUCCH resource sets;

[0262] The first PUSCH resource is configured in one or more PUSCH resource sets;

[0263] The first PUCCH resource or the first PUSCH resource is periodic, semi-persistent, or aperiodic.

[0264] It should be understood that the first threshold value may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0265] Exemplarily, the first threshold may be equal to 2, and the payload of the first PUCCH resource or the first PUSCH resource may be greater than 2 bits, so as to be able to carry the report of the first event.

[0266] It should be understood that a PUSCH resource may be a time-frequency resource allocated by a network device for uplink transmission. A PUSCH resource may have a resource index. Multiple PUSCH resources may form a PUSCH resource set.

[0267] It should be noted that when the first PUCCH resource or the first PUSCH resource is configured through broadcast, all terminal devices can reuse the first PUCCH resource or the first PUSCH resource; when the first PUCCH resource or the first PUSCH resource is configured through multicast, some terminal devices can reuse the first PUCCH resource or the first PUSCH resource; when the first PUCCH resource or the first PUSCH resource is configured through unicast, a single terminal device can use the first PUCCH resource or the first PUSCH resource.

[0268] It should also be noted that, when the first PUCCH resource or the first PUSCH resource is periodic or semi-persistent, the network device may not dynamically indicate the first PUCCH resource or the first PUSCH resource; when the first PUCCH resource or the first PUSCH resource is non-periodic, the network device may dynamically indicate the first PUCCH resource or the first PUSCH resource, for example, the network device may send third information to the terminal device, so that after receiving the third information, the terminal device can obtain one or more first PUCCH resources or first PUSCH resources that can be used for uplink transmission within the second time period.

[0269] It should be understood that if the first event does not meet the preset conditions, the terminal device will not send the first event on the pre-configured first PUCCH resource or the first PUSCH resource. If the network device does not receive the first event on the pre-configured first PUCCH resource or the first PUSCH resource, it is considered that the terminal device side does not need to report the first event.

[0270] It should also be understood that in order to avoid the situation where the terminal device does not have a pre-configured first PUCCH resource and / or first PUSCH resource to carry the report of the first event after determining that the first event meets the preset conditions, the network device can configure the time domain characteristics (such as period) of the first PUCCH resource and / or the first PUSCH resource to be shorter, thereby reducing the reporting delay of the first event.

[0271] Through method #C, the network device can pre-configure the first PUCCH resource or the first PUSCH resource, so that the terminal device does not need to request the first PUCCH resource or the first PUSCH resource from the network device, thereby saving reporting overhead. The terminal device can use the pre-configured first PUCCH resource or the first PUSCH resource to carry the report of the first event, thereby reducing reporting overhead and configuration overhead without delaying the terminal device's switching of the serving space filter.

[0272] Method #D: The terminal device can obtain the first PUCCH resource or the first PUSCH resource based on the Random Access Channel (RACH) process, and thus carry the report of the first event based on the first PUCCH resource or the first PUSCH resource.

[0273] It should be noted that whether the first event meets the preset conditions and the RACH process are both highly random and are triggered by the terminal device. Therefore, the two have similar time domain characteristics and can be used in combination with each other.

[0274] The following describes how the terminal device obtains the first PUCCH resource or the first PUSCH resource for different RACH processes in conjunction with FIG9 and FIG10 .

[0275] FIG9 is a fourth detailed flow diagram of a communication method provided in an embodiment of the present application. As shown in FIG9 , the detailed flow may include the following steps:

[0276] S910. In a four-step RACH process, at a first RACH opportunity, the terminal device sends a first physical random access channel (PRACH) to the network device, where the first PRACH is used to request a first PUCCH resource or a first PUSCH resource.

[0277] S920. The network device sends fourth information to the terminal device, where the fourth information is used to indicate a first PUCCH resource or a first PUSCH resource.

[0278] S930. On a first PUCCH resource or a first PUSCH resource, the terminal device sends a first event to the network device.

[0279] The first event is used by the network device to determine a first service space filter in a first time period.

[0280] Exemplarily, the first RACH opportunity may be a dedicated RACH opportunity, where the dedicated RACH opportunity refers to a RACH opportunity specifically used to request a first PUCCH resource or a first PUSCH resource that carries a first event.

[0281] Exemplarily, after receiving the first PRACH, the network device may allocate a first PUSCH resource or a first PUCCH resource to the terminal device in a random access response (Random Access Response, RAR).

[0282] It should be noted that the terminal device sends the first PRACH to the network device either after the terminal device determines that the first event meets the preset conditions or before the terminal device determines that the first event meets the preset conditions. This embodiment of the present application does not limit this.

[0283] It should also be noted that, when the terminal device determines that the first event meets the preset condition, the terminal device sends the first event to the network device on the first PUCCH resource or the first PUSCH resource. In other words, when the terminal device determines that the first event meets the preset condition, it executes S930.

[0284] FIG10 is a fifth detailed flow diagram of a communication method provided in an embodiment of the present application. As shown in FIG10 , the detailed flow may include the following steps:

[0285] S1010. In a two-step RACH process, at a second RACH opportunity, the terminal device sends a second PRACH and a first event to the network device, where the second RACH opportunity is related to a first PUCCH resource or a first PUSCH resource.

[0286] The first event is used by the network device to determine a first service space filter in a first time period.

[0287] Exemplarily, the second RACH opportunity may be a dedicated RACH opportunity, where the dedicated RACH opportunity refers to a RACH opportunity specifically used to request a first PUCCH resource or a first PUSCH resource that carries a first event.

[0288] It should be noted that the terminal device sends the second PRACH and the first event to the network device after the terminal device determines that the first event meets the preset conditions.

[0289] Exemplarily, after the terminal device determines that the first event meets the preset condition, it can send the second PRACH and the first event on the second RACH timing corresponding to the message (Message, Msg).A.

[0290] It should be noted that the second RACH opportunity is related to the first PUCCH resource or the first PUSCH resource. It can be understood that the terminal device can determine the time-frequency resources corresponding to the second RACH opportunity as the first PUCCH resource or the first PUSCH resource for uplink transmission, so that the second PRACH and the first event can be sent to the network device on the first PUCCH resource or the first PUSCH resource for uplink transmission.

[0291] Through method #D, the terminal device can obtain the first PUCCH resource or the first PUSCH resource based on the RACH process, and thus carry the report of the first event based on the first PUCCH resource or the first PUSCH resource, which not only reduces the reporting overhead and configuration overhead, but also does not delay the terminal device's switching of the service space filter.

[0292] Method #E: The network device can predict that the first event meets the preset conditions, thereby being able to indicate the first PUCCH resource or the first PUSCH resource to the terminal device, so that the terminal device carries the report of the first event based on the first PUCCH resource or the first PUSCH resource.

[0293] FIG11 is a sixth detailed flow diagram of a communication method provided in an embodiment of the present application. As shown in FIG11 , the detailed flow may include the following steps:

[0294] S1110. The network device sends fifth information to the terminal device, where the fifth information is used to instruct the terminal device to send a second event.

[0295] S1120. The terminal device sends a second event to the network device.

[0296] S1130. The network device determines, based on the second event, that the first event satisfies a preset condition.

[0297] S1140. The network device sends sixth information to the terminal device, where the sixth information is used to indicate a first PUCCH resource or a first PUSCH resource.

[0298] The first event is used by the network device to determine a first service space filter in a first time period.

[0299] The second event is used by the network device to determine whether the first event meets a preset condition.

[0300] It should be noted that the second event may include one or more of the following:

[0301] an index of a reference signal resource corresponding to the third serving spatial filter;

[0302] link quality of the reference signal resource corresponding to the third serving spatial filter;

[0303] The index of the reference signal resource corresponding to the candidate spatial filter;

[0304] link quality of the reference signal resource corresponding to the candidate spatial filter;

[0305] a fluctuation range of the link quality of the reference signal resource corresponding to the third serving spatial filter;

[0306] Interference strength of the candidate spatial filter on the third serving spatial filter;

[0307] The third service space filter is a service space filter for a sixth time period, and the end time of the sixth time period is earlier than the start time of the third time period.

[0308] It should be understood that, since the end time of the third time period is earlier than the start time of the first time period, the end time of the sixth time period is also earlier than the start time of the first time period.

[0309] That is, the second event is an event before the current moment, and the second event can also be called a historical event.

[0310] It should be understood that the content included in the second event is similar to that of the first event. You can refer to the relevant description in the first event and will not repeat it here.

[0311] In some embodiments, the network device determines that the first event meets the preset condition based on the second event, which may include: the network device determines the confidence level that the first event meets the preset condition based on the second event; when the confidence level is greater than a seventh threshold, determining that the first event meets the preset condition.

[0312] It should be understood that the seventh threshold may be a parameter value predefined by the protocol, or a parameter value set by other means, and this embodiment of the present application does not limit this.

[0313] It should be noted that, when the confidence level is greater than the seventh threshold, the terminal device can predict that the first event meets the preset conditions, and thus can further predict that the terminal device needs to report the first event, and the terminal device does not have sufficient first PUCCH resources or first PUSCH resources to carry the report of the first event. At this time, the network device can indicate the first PUCCH resource or the first PUSCH resource to the terminal device in advance, so that the terminal device can carry the report of the first event based on the first PUCCH resource or the first PUSCH resource.

[0314] There are two ways for the network device to determine whether the first event meets the preset condition based on the second event.

[0315] In one possible implementation, the network device may directly determine whether the first event meets a preset condition based on the second event.

[0316] Exemplarily, when the link quality of the reference signal resources corresponding to the third service space filter is poor during the sixth time period, the terminal device may deem that the link quality of the reference signal resources corresponding to the second service space filter is also poor during the third time period, thereby predicting that the first event meets the preset conditions.

[0317] Exemplarily, when the link quality of the reference signal resources corresponding to the candidate spatial filter is better in the sixth time period, the terminal device may deem that the link quality of the reference signal resources corresponding to the candidate spatial filter is also better in the third time period, thereby predicting that the first event meets the preset conditions.

[0318] Through this method, the network device can directly determine that the first event meets the preset condition based on the second event, and thus can indicate the first PUCCH resource or the first PUSCH resource to the terminal device. The terminal device can use the first PUCCH resource or the first PUSCH resource indicated by the network device to carry the report of the first event, without having to request the first PUCCH resource or the first PUSCH resource from the network device. This reduces reporting overhead and configuration overhead and does not delay the terminal device's switching of the serving space filter.

[0319] In another possible implementation, the network device may input the second event into the first model to determine whether the first event meets a preset condition.

[0320] Exemplarily, the first model may be an AI / ML model.

[0321] Exemplarily, the first model may be trained in advance by the network device.

[0322] It should be noted that the network device may input the second event into the first model, and determine through the first model that the confidence level that the first event meets the preset condition is greater than the seventh threshold, thereby predicting that the first event meets the preset condition.

[0323] Through this method, the network device can input the second event into the first model, determine that the first event meets the preset conditions, and thus indicate the first PUCCH resource or the first PUSCH resource to the terminal device. The terminal device can use the first PUCCH resource or the first PUSCH resource indicated by the network device to carry the report of the first event, without having to request the first PUCCH resource or the first PUSCH resource from the network device. This reduces reporting overhead and configuration overhead and does not delay the terminal device's switching of the serving space filter.

[0324] It should be noted that when the network device predicts that the first event does not meet the preset conditions, it can be considered that the terminal device does not need to report the first event, and then the first PUCCH resource or the first PUSCH resource is not indicated to the terminal device, thereby saving configuration overhead.

[0325] It should also be noted that after the terminal device receives the first PUCCH resource or the first PUSCH resource indicated by the network device, if it determines that the first event meets the preset conditions, the indicated first PUCCH resource or the first PUSCH resource can be used to carry the report of the first event; if the terminal device determines that the first event does not meet the preset conditions, it means that the network device's prediction is wrong. At this time, the terminal device can ignore the indicated first PUCCH resource or the first PUSCH resource and not make any uplink reports. For the behavior of the terminal device not making any reports, the network device can assume that the terminal device does not need to report the first event, and the prediction of the first model on the network device side is inaccurate.

[0326] Through method #E, the network device can predict that the first event meets the preset conditions, thereby being able to indicate the first PUCCH resource or the first PUSCH resource to the terminal device, so that the terminal device carries the report of the first event based on the first PUCCH resource or the first PUSCH resource, and does not need to request the first PUCCH resource or the first PUSCH resource from the network device itself, which reduces the reporting overhead and configuration overhead and does not delay the terminal device's switching of the service space filter.

[0327] It should be noted that, when there are multiple first PUCCH resources or first PUSCH resources, Methods #A to #E can be used in combination and are not mutually exclusive. For example, a terminal device may obtain a portion of the first PUCCH resources or first PUSCH resources based on Method #A, and then obtain another portion of the first PUCCH resources or first PUSCH resources based on Method #C; for another example, a terminal device may obtain a portion of the first PUCCH resources or first PUSCH resources based on Method #B, and then obtain another portion of the first PUCCH resources or first PUSCH resources based on Method #E; for another example, a terminal device may obtain a portion of the first PUCCH resources or first PUSCH resources based on Method #C, and then obtain another portion of the first PUCCH resources or first PUSCH resources based on Method #D and Method #E.

[0328] In some embodiments, when there are multiple first PUCCH resources or first PUSCH resources, the terminal device sending the first event to the network device on the first PUCCH resource or the first PUSCH resource may include:

[0329] Selecting a first PUCCH resource or a first PUSCH resource based on indexes of multiple first PUCCH resources or first PUSCH resources;

[0330] A first event is sent to a network device on a first PUCCH resource or a first PUSCH resource; wherein:

[0331] A first PUCCH resource or a first PUSCH resource is randomly selected; or,

[0332] The index of a first PUCCH resource or a first PUSCH resource is the lowest or the highest.

[0333] Accordingly, when there are multiple first PUCCH resources or first PUSCH resources, the network device receiving the first event sent by the terminal device on the first PUCCH resource or the first PUSCH resource may include:

[0334] A first event sent by a terminal device is received on a first PUCCH resource or a first PUSCH resource; wherein:

[0335] A first PUCCH resource or a first PUSCH resource is randomly selected; or,

[0336] The index of a first PUCCH resource or a first PUSCH resource is the lowest or the highest.

[0337] It should be noted that, when the terminal device determines that the first event meets the preset conditions, it can use a first PUCCH resource among multiple first PUCCH resources or a first PUSCH resource among the first PUSCH resources to report the first event. In the process of selecting a first PUCCH resource or a first PUSCH resource, the terminal device can randomly select a first PUCCH resource based on the index of multiple first PUCCH resources, or randomly select a first PUSCH resource based on the index of multiple first PUSCH resources; or, the terminal device can select a first PUCCH resource or a first PUSCH resource according to a predefined rule, for example, selecting a first PUCCH resource or a first PUSCH resource with the lowest or highest index.

[0338] Through this method, when there are multiple first PUCCH resources or first PUSCH resources, one first PUCCH resource or first PUSCH resource can be selected from multiple first PUCCH resources or first PUSCH resources, thereby avoiding resource conflicts between multiple terminal devices.

[0339] In some embodiments, the terminal device may send first capability information to the network device, where the first capability information is used to indicate that the terminal device supports obtaining a first event and / or supports sending a first event.

[0340] Accordingly, the network device may receive the first capability information sent by the terminal device.

[0341] Through this method, after receiving the first capability information, the network device can learn that the terminal device supports obtaining the first event and / or supports sending the first event. The network device can subsequently indicate or pre-configure the reference signal resources required for obtaining the first event and / or the first PUCCH resources or first PUSCH resources required for sending the first event for the terminal device based on the first capability information.

[0342] In some embodiments, the first capability information may include one or more of the following:

[0343] The terminal device supports requesting a first PUSCH resource based on the first SR;

[0344] The terminal device supports requesting the first PUCCH resource based on the second SR;

[0345] The terminal device supports requesting the first PUCCH resource or the first PUSCH resource based on the first PRACH.

[0346] In some embodiments, the network device may send seventh information to the terminal device, where the seventh information may be used to indicate one or more of the following:

[0347] a reference signal resource corresponding to the second serving spatial filter;

[0348] Reference signal resources corresponding to candidate spatial filters;

[0349] a first PUCCH resource;

[0350] First PUSCH resource;

[0351] The second service space filter is a service space filter for a third time period, and an end time of the third time period is earlier than a start time of the first time period.

[0352] Correspondingly, the terminal device can receive the seventh information sent by the network device.

[0353] Further, in some embodiments, the seventh information may be related to the first capability information.

[0354] It should be noted that when the terminal device obtains the reference signal resources corresponding to the second service spatial filter and / or the reference signal resources corresponding to the candidate spatial filter, the terminal device can measure the reference signal on these reference signal resources to obtain the first event, and further determine whether the first event meets the preset conditions.

[0355] It should also be noted that when the terminal device obtains the first PUCCH resource and / or the first PUSCH resource, if the terminal device determines that the first event meets the preset conditions, the first event can be sent on the first PUCCH resource and / or the first PUSCH resource, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service space filter.

[0356] It should be understood that the way in which the terminal device obtains the first PUCCH resource or the first PUSCH resource can refer to the aforementioned method #A to method #E, and the embodiments of the present application will not be repeated here.

[0357] In an embodiment of the present application, the network device may also indicate or pre-configure a mixed first PUSCH resource and a first PUCCH resource, and the terminal device may use the mixed first PUSCH resource and the first PUCCH resource to carry the report of the first event. The exemplary description of the network device indicating or pre-configuring the mixed first PUSCH resource and the first PUCCH resource is similar to the network device indicating or pre-configuring the first PUSCH resource or the first PUCCH resource, and will not be repeated here.

[0358] An embodiment of the present application provides a communication method, in which, when a first event meets a preset condition, a terminal device can send a first event to a network device on a first PUCCH resource or a first PUSCH resource, and the first event is used by the network device to determine a first service space filter for a first time period. In this way, after determining that the first event meets the preset condition, the terminal device can carry the report of the first event through the first PUCCH resource or the first PUSCH resource. In this way, the terminal device can actively report the first event, thereby reducing the reporting overhead and configuration overhead, and will not delay the terminal device's switching of the service space filter.

[0359] The communication method provided in the embodiment of the present application is described in detail below in conjunction with specific application scenarios.

[0360] For ease of description, the following embodiments use "beam (pair)" to represent "spatial filter." In other words, in some scenarios, "beam (pair)" and "spatial filter" can be used interchangeably.

[0361] The UE's determination of whether a beam management event (i.e., the first event) meets the preset conditions is somewhat random, and the NW cannot accurately allocate or schedule the first PUCCH resource or the first PUSCH resource in advance to carry the report of the beam management event. Therefore, the embodiments of the present application consider and design multiple ways to request the NW to allocate the first PUCCH resource or the first PUSCH resource, such as pre-allocating a public or dedicated first PUCCH resource or the first PUSCH resource, and for example, predicting the allocation timing of the first PUCCH resource or the first PUSCH resource through an AI / ML model (i.e., the first model).

[0362] Given that the UE has more accurate and timely observations of beam quality changes, a UE-initiated beam reporting process (i.e., reporting the first event) can result in more timely beam reports while reducing reporting overhead. For example, if the UE determines that the current beam quality has deteriorated, it can proactively trigger beam reporting without requiring NW allocation or frequent reporting.

[0363] The embodiment of the present application considers reporting a beam management event for the UE to strive for the first PUCCH resource or the first PUSCH resource. To this end, several situations in which the beam management event meets the preset conditions can be defined by way of examples.

[0364] In some embodiments, beam management events may include one or more of the following:

[0365] The link quality of the reference signal resource corresponding to the serving beam (i.e., the second serving spatial filter) of the serving cell is better than a specific threshold (i.e., the second threshold);

[0366] The link quality of the reference signal resource corresponding to the serving beam of the serving cell is weaker than a specific threshold (i.e., a second threshold);

[0367] The link quality of the reference signal resource corresponding to the candidate beam of the serving cell is better than the link quality of the current serving beam plus the offset;

[0368] The link quality of the reference signal resource corresponding to the candidate beam of the non-serving cell is better than that of the current serving beam plus the offset;

[0369] The link quality of the reference signal resource corresponding to the candidate beam of the serving cell is better than a specific threshold (i.e., a third threshold);

[0370] The link quality of the reference signal resource corresponding to the candidate beam of the non-serving cell is better than a specific threshold (i.e., a third threshold);

[0371] The link quality of the reference signal resource corresponding to the serving beam of the serving cell is weaker than a specific threshold (i.e., the second threshold), and the link quality of the candidate beam of the serving cell is better than a specific threshold (i.e., the third threshold);

[0372] The link quality of the reference signal resources corresponding to the serving beam of the serving cell is weaker than a specific threshold (i.e., the second threshold), and the link quality of the reference signal resources corresponding to the candidate beams of the non-serving cells is better than a specific threshold (i.e., the third threshold);

[0373] The fluctuation range of the link quality of the reference signal resource corresponding to the serving beam of the serving cell exceeds a certain range (i.e., a preset range);

[0374] The interference intensity of the candidate beam of the serving cell to the serving beam of the serving cell is stronger than a certain threshold (i.e., a fourth threshold);

[0375] The interference intensity of the candidate beam of the non-serving cell to the serving beam of the serving cell is stronger than a certain threshold (ie, a fourth threshold).

[0376] The link quality of the serving beam or candidate beam can be measured using physical layer metrics such as L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and PDCCH BLER. These metrics can also serve as link quality input and output for AI / ML models. For PDCCH BLER, the UE can convert the measured L1-SINR into PDCCH BLER based on the conditions defined in the standard. Generally, if the PDCCH BLER is higher than 1%, the link quality is considered poor and needs to be adjusted.

[0377] For beam link quality fluctuations during beam management events, see Figure 4. In some embodiments, it is characterized by the number of times the link quality crosses a predefined threshold (i.e., the fifth threshold) from top to bottom within a time length (e.g., a time window) (i.e., the fourth time period).

[0378] In other embodiments, the indicator for measuring link performance fluctuations may be the duration of time during which the link quality is below a specific threshold (i.e., the sixth threshold) within a specific time period (e.g., a time window) (i.e., the fifth time period), as shown in FIG5 . Alternatively, the indicator may be the ratio of the duration during which the link quality is below a specific threshold to the total time period.

[0379] Figure 3 shows the serving beam, candidate beams in a serving cell, and candidate beams in a non-serving cell. It should be noted that NR supports inter-cell beam management in Release 17, meaning that beams in non-serving cells can also be converted into serving beams.

[0380] For example, when the candidate beam of the non-serving cell or the serving cell is better than the current serving beam plus an offset (such as 3dB), the UE can find through measurement that the beam management event meets the preset conditions, and thus trigger the reporting of the beam management event.

[0381] After the UE discovers through measurement that the beam management event meets the preset conditions, the UE can report one or more of the beam management events to the NW.

[0382] The index of the reference signal resource corresponding to the serving beam;

[0383] The link quality of the reference signal resource corresponding to the serving beam;

[0384] The index of the reference signal resource corresponding to the candidate beam;

[0385] Link quality of the reference signal resources corresponding to the candidate beam;

[0386] The fluctuation range of the link quality of the reference signal resource corresponding to the serving beam;

[0387] The interference strength of the candidate beam on the serving beam.

[0388] It should be noted that the candidate beam and the serving beam can each correspond to a reference signal resource; the index of the non-serving cell can be represented by PCI.

[0389] The UE may inform the NW via capability reporting (i.e., first capability information) whether it supports measurement and / or reporting of beam management events. If supported, the UE may inform the NW of the types of beam management events supported for measurement and / or reporting.

[0390] According to the UE's capability report, the NW can allocate the reference signal resources and / or reporting resources (i.e., the first PUCCH resources or the first PUSCH resources) required for beam management event measurement.

[0391] The UE measures the reference signal on the reference signal resources allocated by the NW to determine whether the beam management event meets the preset conditions.

[0392] When the UE determines that a beam management event meets the preset conditions and needs to report the beam management event to the NW, the UE needs to obtain reporting resources (i.e., first PUCCH resources or first PUSCH resources) to carry the reporting of the beam management event. It can be assumed that the UE does not have pre-allocated reporting resources within a certain time window, such as PUSCH scheduled by uplink DCI, RRC configured Type 1 CG-PUSCH, or DCI activated Type 2 CG-PUSCH.

[0393] When the UE reports a beam management event, the UE may report the index of the reference signal resource corresponding to the candidate beam (from the serving cell or the candidate cell). The index of the reference signal resource may be associated with a unified TCI state, that is, the unified TCI state includes the reference signal (such as implemented by the RRC configuration of the NW). After the UE completes the reporting of the beam management event, the UE expects beam indication information from the NW. For example, the NW may indicate the unified TCI State to the UE through DCI signaling or MAC CE signaling.

[0394] For uplink channel and signal transmission, a unified TCI state can be associated with an uplink TAG, corresponding to a TA value. Furthermore, the unified TCI state can be associated with a set of uplink power control parameters, including P0, Alpha, CLI, and PL RS.

[0395] For downlink channel and signal transmission, the reported reference signal index (such as CRI) can be associated with a set of CSI information, including PMI, RI, CQI, etc. This association can be understood as the CSI on each beam (Per Beam).

[0396] The UE can obtain the first PUCCH resource or the first PUSCH resource to carry the report of the beam management event. The following seven embodiments illustrate how the UE obtains the first PUCCH resource or the first PUSCH resource.

[0397] Embodiment 1: The first SR requests the first PUSCH resource to carry the report of the beam management event.

[0398] The uplink scheduling request in the related art is a request for PUSCH resources, but the content carried is either high-layer data or MAC CE of the MAC layer.

[0399] The embodiment of the present application is designed to use the first SR to request the first PUSCH resource to carry the reporting of the beam management event.

[0400] Note 1: Since periodic / semi-persistent / aperiodic beam reporting also falls under the category of CSI reporting in the standard, reporting based on beam management events can be understood as CSI reporting.

[0401] Note 2: The second PUCCH format carrying the first SR often has a small payload (no more than 2 bits) and cannot carry the reporting of a complete beam management event.

[0402] The UE needs to report the first capability information to indicate whether it supports using the first SR to request reporting of the first PUSCH bearer beam management event.

[0403] In some embodiments, the UE sends a first SR to the NW on a second PUCCH resource associated with a special SR opportunity (i.e., a first SR opportunity). This special feature is that the first SR opportunity is specifically used to request a first PUSCH resource that carries a beam management event. This first SR is configured by the NW through RRC and is different from the SR used to request a PUSCH to carry upper layer data or MAC CE. The NW can configure a special SR (i.e., a first SR) that can be used to request a first PUSCH resource.

[0404] In some embodiments, a conventional SR (i.e., a first SR) is used, but the scheduling request information contained in the first SR is not limited to a single bit (i.e., "0" indicates no scheduling request and "1" indicates a scheduling request). The first SR may include the type of information requested to be carried by the first PUSCH. For example, 2 bits of scheduling request information may be designed, and its codepoints may represent the following information.

[0405] "00" means no scheduling request;

[0406] "01" indicates a request in the related art for the first PUSCH to carry upper layer data or uplink MAC CE;

[0407] "10" indicates that the first PUSCH is requested to carry the report of the beam management event;

[0408] "11" is used as a reserved bit.

[0409] With this method, the UE can inform the network network (NW) in its uplink resource request (i.e., sending the first SR) that the beam management event carried by the requested first PUSCH resource is important. Reporting of beam management events often involves changes in link quality and may even result in beam failure. The NW can allocate the first PUSCH resource to the UE based on the importance of the first SR.

[0410] Exemplarily, the NW may allocate the first uplink PUSCH resource to the UE through uplink DCI.

[0411] It should be noted that for uplink resource requests based on the first SR, the UE needs to wait for the periodic uplink first SR opportunity. If the period is configured too long, beam management events will not be reported in a timely manner; if the period is configured too short, a certain amount of second PUCCH resources must be reserved for multiple reports of beam management events.

[0412] Embodiment 2: The second SR requests the first PUCCH resource to carry the report of the beam management event.

[0413] The SR in the related art can be used to request PUSCH resources, but is not used to request PUCCH resources.

[0414] This embodiment of the present application designs another special SR (i.e., the second SR) that can request the first PUCCH resource. This second SR itself is carried by a third PUCCH resource with a smaller payload (no more than 2 bits). The first PUCCH resource requested by the second SR has a larger payload (more than 2 bits), which is sufficient to carry the report of the beam management event.

[0415] When the second SR opportunity arrives, the UE can use the third PUCCH resource associated with the second SR opportunity to request the first PUCCH resource. The payload of the third PUCCH resource is insufficient to carry the report of the beam management event, but the UE can send a second SR to the NW through the third PUCCH resource to request the first PUCCH resource to carry the report of the beam management event.

[0416] The NW may configure the second SR through RRC signaling to request the first PUCCH resources, and distinguish it from the SR requesting the PUSCH resources.

[0417] In some embodiments, the NW responds to the UE's second SR. For example, the NW activates one or more UE-specific first PUCCH resources through DCI scheduling or MAC CE. The first PUCCH resources can be used to carry beam management event reports.

[0418] In some embodiments, the NW activates a common first PUCCH resource for the UE via a DCI indication or a MAC CE. Subsequently, the UE may use the common first PUCCH resource to carry reports of beam management events.

[0419] With this method, the uplink resource requested by the second SR is a public or dedicated first PUCCH resource. Compared to PUSCH, reporting beam management events carried by the first PUCCH resource only occupies a small amount of uplink time-frequency resources. During the resource indication or activation process, a small amount of information can also be used to indicate the allocated first PUCCH resource.

[0420] Embodiment 3: Pre-configure a common first PUCCH resource or a first PUSCH resource.

[0421] In some embodiments, the UE carries the reporting of beam management events based on a pre-configured common first PUCCH resource or first PUSCH resource (or resource set). The configuration of the common first PUCCH resource or first PUSCH resource is characterized by a common attribute. It is not exclusive to a single UE, but multiple UEs can transmit information on the same first PUCCH resource or first PUSCH resource in a multiplexing manner.

[0422] The characteristics of the common first PUCCH resource or the first PUSCH resource may include one or more of the following:

[0423] The payload is large (no more than 2 bits), which is sufficient to carry the reporting of beam management events;

[0424] The NW is configured through broadcast or multicast information, which applies to all or some UEs;

[0425] Configured in one or more PUCCH resource sets;

[0426] Configured in one or more PUSCH resource sets;

[0427] The time domain feature is periodic or semi-persistent (it can be used without the need for dynamic indication by the NW or SR request).

[0428] Through this method, the overhead of the first PUCCH resource or the first PUSCH resource is saved, and the NW can configure one or more PUCCH resources or first PUSCH resources (or resource sets) to a group of UEs.

[0429] After a UE determines that a beam management event meets a preset condition, it can use a PUCCH resource in the public first PUCCH resource or a PUSCH resource in the public first PUSCH resource to carry the report of the beam management event.

[0430] In some embodiments, when more than one common first PUCCH resource or first PUSCH resource is configured, in order to avoid resource conflicts between multiple UEs, the UE may randomly select a PUCCH resource based on the indexes of multiple common first PUCCH resources, or randomly select a PUSCH resource based on the indexes of multiple common first PUSCH resources.

[0431] In other embodiments, when more than one common first PUCCH resource or first PUSCH resource is configured, in order to avoid resource conflicts between multiple UEs, the UE can select the first PUCCH resource or the first PUSCH resource according to predefined rules, for example, selecting a first PUCCH resource with the lowest or highest index among multiple first PUCCH resources, or selecting a first PSCCH resource with the lowest or highest index among multiple first PUSCH resources.

[0432] In order to avoid the UE determining that when the beam management event meets the preset conditions, the UE has no uplink public first PUCCH resources or first PUSCH resources for reporting, the time domain characteristics (such as period) of the public first PUCCH resources or first PUSCH resources can be configured to be shorter, thereby reducing the reporting delay.

[0433] Embodiment 4: Pre-configure a first PUCCH resource or a first PUSCH resource dedicated to a UE.

[0434] In some embodiments, the NW may pre-configure a dedicated periodic or semi-persistent first PUCCH resource or first PUSCH resource (or resource set) for the UE to carry the reporting of beam management events.

[0435] The characteristics of the UE-specific first PUCCH resource or the first PUSCH resource may include one or more of the following:

[0436] The payload is large (no more than 2 bits), which is sufficient to carry the reporting of beam management events;

[0437] The NW is configured via unicast information (RRC configuration), which is applicable to a single UE;

[0438] Configured in one or more PUCCH resource sets;

[0439] Configured in one or more PUSCH resource sets;

[0440] The time domain feature is periodic or semi-persistent (it can be used without the need for dynamic indication by the NW or SR request).

[0441] For multiple UEs in the NW, if the first PUCCH resources or first PUSCH resources dedicated to the multiple UEs do not support multi-user multiplexing of time-frequency resources, resource interference between the multiple UEs can be avoided by configuring different periods and / or offsets.

[0442] With this method, the UE does not need to send an SR to request the first PUCCH resource or the first PUSCH resource, nor does it need to share the first PUCCH resource or the first PUSCH resource among multiple users. Each UE has a dedicated first PUCCH resource or first PUSCH resource for reporting beam management events.

[0443] When the UE determines that the beam management event meets the preset conditions, the UE may wait for a while (until the next nearest opportunity to send the first PUCCH resource or the first PUSCH resource arrives), and the UE may carry the report of the beam management event on the first PUCCH resource or the first PUSCH resource.

[0444] If the UE determines that the beam management event does not meet the preset conditions, the UE will not report the beam management event on the pre-allocated first PUCCH resource or the first PUSCH resource. If the NW does not receive the UE's report on the pre-allocated dedicated first PUCCH resource or the first PUSCH resource, it is considered that there is no beam management event that needs to be reported on the UE side.

[0445] Embodiment 5: Dynamically indicate the pre-configured first PUCCH resource or the first PUSCH resource.

[0446] In some embodiments, the NW configures multiple periodic, semi-persistent, or aperiodic first PUCCH resources through RRC signaling. The NW may indicate the first PUCCH resources that can be used for uplink transmission within a period of time through DCI signaling. The indication method of the DCI signaling may include one or more of the following:

[0447] For a multicast DCI to multiple UEs, one or more UEs in the group may use the first PUCCH resource indicated by the DCI;

[0448] For a broadcast DCI for all UEs, all UEs can use the first PUCCH resource indicated by the DCI;

[0449] For unicast DCI of a single UE, only the UE that receives the dedicated DCI can use the indicated first PUCCH resource.

[0450] It should be noted that some of the indicated first PUCCH resources have a smaller payload, while others are larger enough to carry the report of the beam management event. After receiving the indication of the available first PUCCH resource, the UE can determine whether the beam management event meets the preset conditions. If the beam management event meets the preset conditions, the UE uses the indicated first PUCCH resource to carry the report of the beam management event; if the beam management event does not meet the preset conditions, the UE does not use the first PUCCH resource.

[0451] In some embodiments, the NW configures one or more Type 1 or Type 2 CG-PUSCH resources through RRC signaling. The NW may indicate the first PUSCH resource that can be used for uplink transmission within a period of time through DCI. Similarly, the DCI indication method may include one or more of the following:

[0452] For a multicast DCI for multiple UEs, one or more UEs in the group may use the first PUSCH resource indicated by the DCI;

[0453] For a broadcast DCI for all UEs, all UEs can use the first PUSCH resource indicated by the DCI;

[0454] For unicast DCI of a single UE, only the UE that receives the dedicated DCI can use the indicated first PUSCH resource.

[0455] It should be noted that, generally, the allocated first PUSCH resource has sufficient load capacity to carry the reporting of beam management events.

[0456] For example, within a period of time (e.g., within the next eight time slots), the NW configures a potentially usable first PUCCH resource or first PUSCH resource for each time slot. The NW then indicates the available resources within the period of time through DCI. For example, a bitmap of {00110100} means that among the upcoming first PUCCH resources or first PUSCH resources, the third, fourth, and sixth first PUCCH resources or first PUSCH resources can be used by the UE for uplink transmission. The remaining first PUCCH resources or first PUSCH resources cannot be used for uplink transmission, thereby avoiding interference with the uplink transmission of other UEs.

[0457] In some embodiments, the NW may also use MAC CE signaling to indicate the first PUCCH resource or the first PUSCH resource that can be used by the UE for uplink transmission within a period of time. It should be noted that MAC CE signaling is UE-specific signaling and does not have broadcast and multicast features. Therefore, the indication of the MAC CE signaling is for a single UE.

[0458] Through this method, the NW can allocate the upcoming first PUCCH resources and / or first PUSCH resources more flexibly, and also avoid the overhead of the UE requesting the first PUCCH resources and / or first PUSCH resources.

[0459] In addition, the NW may also configure mixed first PUSCH resources and first PUCCH resources.

[0460] Embodiment 6: RACH-based first PUCCH resource or first PUSCH resource request.

[0461] In some embodiments, the UE may request a first PUCCH resource or a first PUSCH resource through a RACH process. The first PUCCH resource or the first PUSCH resource may be used to carry a report of a beam management event.

[0462] Figure 12 is a schematic diagram of a process of requesting resource allocation based on a four-step RACH process according to an embodiment of the present application. As shown in Figure 12, the process may include the following steps.

[0463] S1210 : At a first RACH opportunity, the UE sends a first PRACH to the NW.

[0464] The first PRACH is used to request a first PUCCH resource or a first PUSCH resource.

[0465] It should be noted that the first RACH opportunity is a dedicated RACH opportunity, which refers to a RACH opportunity specifically used for beam management event reporting request resources.

[0466] Exemplarily, after the UE determines that the beam management event meets the preset conditions, the UE can send the first PRACH to the NW at the first RACH opportunity.

[0467] S1220. The NW allocates a first PUCCH resource or a first PUSCH resource to the UE in the RAR.

[0468] S1230. The UE sends a beam management event to the NW on the first PUCCH resource or the first PUSCH resource.

[0469] S1240. NW indicates beam information to UE.

[0470] Exemplarily, the NW indicates beam information via a RACH Completion message. For example, the NW indicates the new beam (i.e., the first serving spatial filter) (including one or a set of unified TCI State(s)) in the corresponding PDCCH. Another example is activating the new beam (including one or a set of unified TCI State(s)) via a MAC CE in the corresponding PDSCH. The PDCCH and PDSCH correspond to the RACH Completion message.

[0471] Figure 13 is a schematic diagram of a process of requesting resource allocation based on a two-step RACH process according to an embodiment of the present application. As shown in Figure 13, the process may include the following steps.

[0472] S1310. The UE sends a second PRACH and a beam management event to the NW at the second RACH opportunity.

[0473] Exemplarily, after the UE determines that the beam management event meets the preset conditions, it sends the second PRACH and beam management event to the NW at the second RACH opportunity corresponding to Msg.A.

[0474] S1320. NW indicates beam information to UE.

[0475] Exemplarily, after receiving a report of a beam management event, the NW indicates the new beam (i.e., the first serving spatial filter) corresponding to the beam management event in Msg.B. For example, the NW indicates the new beam (including one or a group of unified TCI State(s)) in the corresponding PDCCH; for another example, the NW activates the new beam (including one or a group of unified TCI State(s)) through a MAC CE in the corresponding PDSCH; wherein the PDCCH and PDSCH correspond to Msg.B.

[0476] Through this method, since beam management events and random access are both highly random and are triggered by UE or driven by events, the two have similar time domain characteristics and can be used in combination.

[0477] Embodiment 7: Prediction and allocation of first PUCCH resources or first PUSCH resources based on AI / ML model.

[0478] In some embodiments, an AI / ML model can be deployed on the network device side, which can predict the confidence level of a beam management event satisfying a preset condition, so that when the confidence level of the predicted beam management event satisfying the preset condition is higher than a certain threshold (i.e., the seventh threshold), the NW can indicate the first PUCCH resource or the first PUSCH resource to the UE.

[0479] It should be noted that the NW can predict the confidence level of a beam management event that meets preset conditions by training an AI / ML model. The UE can report historical beam management events to the NW. The beam management event can be used as input to the AI / ML model. Through the prediction of the AI / ML model, it can be determined whether the beam management event on the UE side meets the preset conditions. For example, when the confidence level of the beam management event output by the AI / ML model that meets the preset conditions is higher than a certain threshold, the AI / ML model can determine that the UE needs to report the uplink resources for the beam management event, and the UE currently does not have sufficient resources for reporting.

[0480] After the NW predicts that the beam management event meets the preset conditions and the UE needs to report the beam management event, the NW can pre-indicate an uplink first PUCCH resource or a first PUSCH resource to the UE for carrying the report of the beam management event.

[0481] After the UE determines that the beam management event meets the preset conditions, the UE can use the pre-allocated or pre-indicated first PUCCH resource or first PUSCH resource to carry the report of the beam management event. After the UE determines that the beam management event does not meet the preset conditions, the UE can choose to ignore the first PUCCH resource or the first PUSCH resource and not make any uplink report. At this time, it can be considered that the AI / ML model prediction on the NW side is wrong. If the UE does not report any behavior, the NW can assume that there is no need to report the beam management event on the UE side and the prediction of the AI / ML model on the NW side is inaccurate.

[0482] It should be noted that the uplink resource prediction mechanism based on the AI / ML model can be used in combination with other uplink resource request mechanisms, and they are not mutually exclusive.

[0483] Through this method, the UE does not need to send an SR to request the first PUCCH resource or the first PUSCH resource. The NW directly indicates the first PUCCH resource or the first PUSCH resource to the UE to carry the reporting of the beam management event, which can reduce the reporting delay of the beam management event.
