[0071] The terms used in the embodiments of the present disclosure are only for the purpose of describing the specific embodiments, and not as a limitation on the present disclosure.

[0072] In the embodiments of the present disclosure, unless otherwise specified, the elements expressed in singular form, such as "one", "a", "the", "above", "said", "preceding", "this" and the like, can represent "one and only one", or "one or more", "at least one" and the like.

[0073] In the embodiments of the present disclosure, "a plurality of" means two or more.

[0085] In some embodiments, the access network device, the core network device, or the network device can be replaced with a terminal. For example, the embodiments of the present disclosure can also be applied to a structure in which communication between the access network device, the core network device, or the network device and the terminal is replaced with communication between a plurality of terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the terminal can also be configured to have all or part of the functions of the access network device. In addition, the terms "uplink," "downlink," and the like can also be replaced with terms corresponding to the inter-terminal communication (e.g., "side"). For example, the uplink channel, the downlink channel, and the like can be replaced with the side channel, and the uplink, the downlink, and the like can be replaced with the sidelink.

[0086] In some embodiments, the terminal can be replaced with the access network device, the core network device, or the network device. In this case, the access network device, the core network device, or the network device can also be configured to have all or part of the functions of the terminal.

[0087] In some embodiments, obtaining data, information, etc. can comply with laws and regulations of the country in which the location is situated.

[0088] In some embodiments, obtaining data, information, etc. can be after obtaining consent from the user.

[0089] In addition, each element, each row, or each column in the table of the embodiments of the present disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0090] In NR, especially when the communication frequency band is in frequency range 2 (above 6 GHz), due to the rapid attenuation of high-frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used.

[0091] The network device can configure periodic, semi-persistent, or aperiodic beam measurement reporting. That is, the terminal can perform beam measurement and report beam reports periodically, semi-persistently, or aperiodically according to the configuration of the network device.

[0092] However, in practice, the terminal can learn the change of beam quality in time, and the reporting period length configured by the network device, or the timing of the aperiodic reporting configured by the network device, may not be appropriate. If the reporting period length configured by the network device is too short, the best K (K is a positive integer) beams reported twice may be the same, thereby causing signaling waste. If the reporting period length configured by the network device is too long, the beams may have changed, but it is not time to report, thereby affecting the communication quality. In the case of aperiodic reporting configured by the network device, there is also a problem that the timing of the network device triggering the terminal to report is too early or too late, thereby causing signaling waste or affecting the communication quality.

[0093] In some embodiments, the current beam can be determined based on the indicated transmission configuration indication (TCI) state. However, the RS included in the indicated TCI state may fall into two categories: one is that the indicated TCI state only includes Type A and Type D, where the reference signals (RS) corresponding to Type A and Type D are the same channel state information reference signal (CSI-RS) configured with a tracking reference signal (TRS); the other is that Type A is a CSI-RS configured with a TRS, and Type D is a CSI-RS configured with a repetition parameter. For the first case, where the RSs in the indicated TCI state are all the same CSI-RS configured with a TRS, since in related technologies, CSI-RS configured with a TRS cannot be used for beam measurement (but CSI-RS configured with repetition can), determining the RS corresponding to the current beam based on this CSI-RS is a problem that needs to be solved.

[0094] This disclosure provides a communication method in which, when a triggering event is met, a terminal sends a first report to a network device, ensuring the timeliness of beam reporting; when reporting the first report based on an event trigger, the terminal can determine whether the triggering event has been triggered based on accurate reference signal resources, thereby ensuring the accuracy of beam reporting.

[0109] In some embodiments, the first reference signal resource is a reference signal resource corresponding to the first beam in the event.

[0110] In some embodiments, the event is used to trigger the terminal to report the first report.

[0111] In some embodiments, the event can include a trigger condition that the current beam and / or the candidate beam satisfies.

[0112] In some embodiments, the first beam in the event can be a current beam. The current beam can also be referred to as a serving beam. The event can also include a candidate beam, which can also be referred to as a new beam, a target beam, a neighboring beam, etc.

[0113] In some embodiments, the first reference signal resource can be a reference signal resource used for beam measurement.

[0114] In some embodiments, the terminal can determine the first reference signal resource corresponding to the current beam included in the trigger event.

[0115] In some embodiments, the beam can also be referred to as: spatial reception parameter (Spatial Rx parameter), quasi co-location (Quasi co-location, QCL) type D (Type D), spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, transmission configuration indication state (Transmission Configuration Indicator, TCI state), joint transmission configuration indication state (joint TCI state), downlink transmission configuration indication state (Downlink TCI state, DL TCI state), uplink transmission configuration indication state (DL TCI state), independent transmission configuration indication state (unified TCI state), common transmission configuration indication state (common TCI state), spatial relation information, etc. The beam can be replaced with any of the above.

[0116] In some embodiments, the terminal can determine the first reference signal resource based on an indicated TCI state. Wherein the indicated TCI state is a TCI state indicated by the network device to the terminal.

[0117] In some embodiments, the network device can indicate the TCI state through a medium access control element (MAC CE) or a MAC CE + downlink control information (DCI).

[0118] For example, the network device activates the indicated TCI state corresponding to one code point of the TCI field in the DCI through the MAC CE.

[0119] For another example, the network device activates the indicated TCI state corresponding to multiple code points of the TCI field in the DCI respectively through the MAC CE, and the network device indicates one code point through the TCI field of the DCI.

Wherein, the reference signal resource corresponding to the first CSI-RS is the reference signal resource indicated by the TCI state indicated by the network device, and the first CSI-RS is configured with TRS information; the second CSI-RS has a quasi-co-location relationship with the first CSI-RS, the second CSI-RS is not configured with TRS information, and the reference signal resource corresponding to the second CSI-RS is not in the reference signal resource indicated by the indicated TCI state; and the first SSB has a quasi-co-location relationship with the first CSI-RS.

[0122] In some embodiments, the first reference signal resource includes at least one of the following: the reference signal resource corresponding to the first CSI-RS, the reference signal resource corresponding to the second CSI-RS, and the reference signal resource corresponding to the first SSB; wherein the reference signal resource corresponding to the first CSI-RS is the reference signal resource indicated by the TCI state indicated by the network device, and the first CSI-RS is configured with TRS information; the second CSI-RS has a quasi-co-location relationship with the first CSI-RS, and the second CSI-RS is not configured with TRS information; and the first SSB has a quasi-co-location relationship with the first CSI-RS.

[0123] In some embodiments, the reference signal resource and the reference signal corresponding to the reference signal resource can be replaced with each other. For example, the reference signal resource is a CSI-RS resource, and the reference signal is a CSI-RS. For example, the reference signal resource is a CSI-RS resource configured with TRS, and the reference signal is TRS. For example, the reference signal resource is an SSB resource, and the reference signal is an SSB.

[0124] In some embodiments, the above step S2101 can include any one of steps S2101a, S2101b, and S2101c.

[0125] Step S2101a, the terminal determines the reference signal resource corresponding to the first CSI-RS as the first reference signal resource.

[0126] In some embodiments, the reference signal resource corresponding to the first CSI-RS is a reference signal resource indicated by the indicated TCI state, and the first CSI-RS is configured with TRS information. The terminal can determine the reference signal resource corresponding to the first CSI-RS as the first reference signal resource, i.e., take the reference signal resource corresponding to the first CSI-RS configured with the TRS information as the first reference signal resource for beam measurement.

[0127] In step S2101b, the terminal determines the reference signal resource corresponding to the second CSI-RS as the first reference signal resource.

[0128] In some embodiments, the second CSI-RS is a CSI-RS having a QCL relationship with the first CSI-RS, the second CSI-RS is not configured with TRS information, and the reference signal resource corresponding to the second CSI-RS is not in the reference signal resources indicated by the indicated TCI state. The terminal can take the reference signal resource corresponding to the second CSI-RS having the QCL relationship with the first CSI-RS as the first reference signal resource for beam measurement.

[0129] In step S2101c, the terminal determines the reference signal resource corresponding to the first SSB as the first reference signal resource.

[0130] In some embodiments, the first SSB is an SSB having a QCL relationship with the first CSI-RS. The terminal can take the reference signal resource corresponding to the SSB having the QCL relationship with the first CSI-RS as the first reference signal resource for beam measurement. The reference signal resource corresponding to the first SSB is not in the reference signal resources indicated by the indicated TCI state.

[0131] In some embodiments, when the serving cell and / or bandwidth part of the terminal is in a first frequency range, the first reference signal resource is determined by at least one of the following: the terminal determines the reference signal resource corresponding to the first CSI-RS as the first reference signal resource; and the terminal determines the reference signal resource corresponding to the first SSB as the first reference signal resource.

[0132] The first frequency range may, for example, be FR1, and the frequency range is in 410MHz-7125MHz.

[0133] In some embodiments, when the serving cell and / or bandwidth part of the terminal is in a first frequency range, the terminal can determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB as the first reference signal resource.

[0134] In some embodiments, when the serving cell and / or the bandwidth part of the terminal is in the first frequency range, the first reference signal resource is the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB.

[0135] In an example, the terminal can determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB as the first reference signal resource through Radio Resource Control (RRC) signaling. That is, the RRC signaling can configure the terminal to determine the reference signal resource corresponding to the first CSI-RS as the first reference signal resource, or the RRC signaling can configure the terminal to determine the reference signal resource corresponding to the first SSB as the first reference signal resource.

[0136] In some embodiments, when the serving cell and / or the bandwidth part of the terminal is in the second frequency range, the first reference signal resource is determined by at least one of the following: the terminal determines the reference signal resource corresponding to the first CSI-RS as the first reference signal resource; the terminal determines the reference signal resource corresponding to the second CSI-RS as the first reference signal resource; the terminal determines the reference signal resource corresponding to the first SSB as the first reference signal resource. That is, when the serving cell and / or the bandwidth part of the terminal is in the second frequency range, the first reference signal resource can be the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB or the reference signal resource corresponding to the second CSI-RS.

[0137] wherein the first frequency range is smaller than the second frequency range. The second frequency range may, for example, be FR2 or FR3, the frequency range of FR2 is 24250MHz-71000MHz, and the frequency range of FR3 is 7125MHz-24250MHz.

[0138] In some embodiments, when the serving cell and / or the bandwidth part of the terminal is in the second frequency range, the terminal can determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource.

[0139] In an example, the terminal can determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource through RRC signaling. That is, the RRC signaling can configure the terminal to determine the reference signal resource corresponding to the first CSI-RS as the first reference signal resource, or the RRC signaling can configure the terminal to determine the reference signal resource corresponding to the first SSB as the first reference signal resource, or the RRC signaling can configure the terminal to determine the reference signal resource corresponding to the second CSI-RS as the first reference signal resource.

[0140] In some embodiments, the terminal can determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the first SSB or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource through the type of the reference signal resource corresponding to the candidate beam.

[0141] In some embodiments, the second reference signal resource includes the reference signal resource corresponding to the first candidate beam, and in a case where the type of the reference signal resource corresponding to the first candidate beam is SSB, the first reference signal resource is the reference signal resource corresponding to the first SSB.

[0142] In other embodiments, the second reference signal resource includes the reference signal resource corresponding to the second candidate beam, and in a case where the type of the reference signal resource corresponding to the second candidate beam is CSI-RS, the first reference signal resource is the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the second CSI-RS, wherein the serving cell and / or bandwidth part of the terminal is in a first frequency range, or the first reference signal resource is the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the second CSI-RS, wherein the serving cell and / or bandwidth part of the terminal is in a second frequency range; wherein the first frequency range is smaller than the second frequency range.

[0143] In other embodiments, the terminal determines the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource through the received RRC signaling.

[0144] For example, in a case where the type of the reference signal resource corresponding to the first candidate beam is SSB, the terminal determines the reference signal resource corresponding to the first SSB as the first reference signal resource.

[0145] For another example, in a case where the serving cell and / or bandwidth part of the terminal is in a first frequency range, the type of the reference signal resource corresponding to the second candidate beam is CSI-RS, the terminal determines the reference signal resource corresponding to the first CSI-RS as the first reference signal resource.

[0146] For example, in a case that the serving cell and / or the bandwidth part of the terminal is in the second frequency range, the type of the reference signal resource corresponding to the second candidate beam is CSI-RS, the terminal determines the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource. In this case, the terminal can further determine to determine the reference signal resource corresponding to the first CSI-RS or the reference signal resource corresponding to the second CSI-RS as the first reference signal resource through the received RRC signaling.

[0147] The communication method provided by the embodiments of the present disclosure can enable the terminal to determine the reference signal resource corresponding to the first beam in the triggering event when the RS indicated by the indicated TCI state is the CSI-RS configured with only the TRS, and enable the terminal to accurately determine the reference signal resource for beam measurement, thereby guaranteeing the reliability of the beam report triggered based on the triggering event.

[0148] In step S2102, when the triggering event is met, the terminal sends a first report to the network device.

[0149] In some embodiments, the first report may, for example, be a beam report, and the beam report may, for example, be referred to as a beam measurement report.

[0150] In some embodiments, the first report is used to report the reference signal resource and / or the measurement result corresponding to the reference signal resource. The first report can be used to report the second reference signal resource and / or the measurement result corresponding to the second reference signal resource. The second reference signal resource may, for example, be the first reference signal resource, or may, for example, be a reference signal resource different from the first reference signal resource. The second reference signal resource may, for example, include the first reference signal resource. The first reference signal resource is the reference signal resource corresponding to the first beam in the triggering event. For example, the first report is used to report the second reference signal resource. For example, the first report is used to report the measurement result corresponding to the second reference signal resource. For example, the first report is used to report the second reference signal resource and the measurement result corresponding to the second reference signal resource.

[0151] In some embodiments, the second reference signal resource includes the reference signal resource corresponding to the current beam and / or the candidate beam.

[0152] In some embodiments, the first report comprises at least one of: an identification (RSID) of the second reference signal resource; a Layer 1 reference signal receiving power (L1-RSRP); a Layer 1 signal to interference plus noise ratio (L1-SINR); a capability index; a power headroom; a power backoff; an uplink transmission power; an event ID; a TCI state ID.

[0156] In some embodiments, the second reference signal resource comprises a reference signal resource corresponding to a current beam and / or a candidate beam; and the event comprises at least one of: a quality of the current beam being lower than a first threshold; a quality of the candidate beam being higher than a second threshold; a difference between the quality of the candidate beam and the quality of the current beam being higher than a third threshold.

[0157] In some embodiments, the quality of the beam can be a L1-RSRP, or a L1-SINR, or an uplink transmission power, which is not limited in the present disclosure.

[0158] In some embodiments, when the current beam being monitored is a joint TCI state or a UL TCI state, and / or the candidate beam to be monitored is used for a joint TCI state or a UL TCI state, the quality of the beam can be the uplink transmission power.

[0159] In some embodiments, the values of the first threshold, the second threshold, and the third threshold can be set according to actual conditions. The first threshold and the second threshold can be the same or different.

[0160] In some embodiments, the trigger event can include the current beam or the candidate beam. When the trigger event includes monitoring the current beam, the terminal can determine the reference signal resource corresponding to the current beam based on the configuration of the network device; when the trigger event includes monitoring the candidate beam, the terminal can determine the reference signal resource corresponding to the candidate beam based on the configuration of the network device.

[0161] In some embodiments, the terminal can send a beam report to the network device when the trigger event is satisfied based on the trigger event and the determined first reference signal resource.

[0162] In some embodiments, the terminal can determine the first reference signal resource corresponding to the first beam included in the trigger event, then measure the first reference signal resource, and determine whether the trigger condition is satisfied based on the measurement result of the first reference signal resource. When the measurement result satisfies the trigger condition in the trigger event, the terminal sends a beam report to the network device.

[0163] The communication method provided by the embodiments of the present disclosure can ensure the timeliness and effectiveness of the beam report when the first report is reported based on the event trigger, because the reference signal resource reported by the terminal can be the reference signal resource corresponding to the beam in the trigger event, and the terminal can determine whether the trigger event is triggered based on the accurate reference signal resource.

[0202] The embodiments of the present disclosure provide a communication method. In the beam reporting based on UE initiation or the beam reporting based on event triggering, a terminal determines a current beam, so that when the RS indicated by the indicated TCI state is a CSI-RS configured with only TRS, the terminal can explicitly trigger the RS corresponding to the current beam in the event, thereby ensuring the reliability of the beam report triggered based on the triggering event.

[0203] In some embodiments, the terminal determines a first reference signal resource, which is a reference signal resource corresponding to the current beam in the event. Based on the first reference signal resource and the event, the terminal sends a beam report when the triggering condition of the event is met.

[0204] In some embodiments, the terminal determines the first reference signal resource based on the indicated TCI state.

[0205] In some embodiments, the indicated TCI state can include an indicated joint TCI state, a DL TCI state, or an UL TCI state.

[0206] In some embodiments, when the RSs of QCL Type A and QCL Type D indicated by the indicated TCI state are both the first CSI-RS configured with TRS information, the first reference signal resource can be determined by at least one of method one, method two, and method three.

[0207] Method one: the terminal determines a second CSI-RS having a QCL relationship with the first CSI-RS as the first reference signal resource. The second CSI-RS is not configured with TRS information.

[0208] Method two: the terminal determines an SSB having a QCL relationship with the first CSI-RS as the first reference signal resource.

[0209] Method three: the terminal determines the first CSI-RS as the first reference signal resource. That is, the terminal uses the first CSI-RS configured with TRS information as the first reference signal resource for beam measurement.

[0210] In some embodiments, when the terminal is in FR1 (410MHz-7125MHz), the first reference signal resource can be determined by using the above-mentioned method two or method three.

[0211] In an example, the terminal can be configured by RRC to use Method 1, Method 2 or Method 3 to determine the first reference signal resource.
