[0088] 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.

[0089] 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.

[0090] In some embodiments, obtaining data, information, and the like can comply with laws and regulations of the country in which the location is situated.

[0091] In some embodiments, data, information, and the like can be obtained after user consent.

[0092] Furthermore, 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.

[0093] In NR, especially when the communication frequency band is in frequency range 2 (above 7 GHz), due to the rapid attenuation of high-frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used.

[0094] The network device can configure periodic, semi-persistent, or aperiodic beam measurement reporting. That is, the terminal can perform beam measurement and report a beam report periodically, semi-persistently, or aperiodically according to the configuration of the network device.

[0095] However, in practice, the terminal can learn the change in 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.

[0096] In some embodiments, the current beam can be determined based on the indicated transmission configuration indication (TCI) state. However, the reference signal (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 RSs 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.

[0097] This disclosure provides a communication method in which a terminal determines at least one reference signal resource in a second reference signal resource configured with TRS information as the first reference signal resource corresponding to the current beam in an event, thereby determining whether a triggering event has been triggered based on accurate reference signal resources, ensuring the accuracy of beam reporting; when a triggering event is met, the terminal sends a first report to the network device, which can ensure the timeliness of beam reporting.

[0110] Figure 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2 the present embodiment relates to a communication method, the method comprising:

[0111] In step S2101, the terminal determines a first reference signal resource.

[0112] In some embodiments, the first reference signal resource is a reference signal resource corresponding to the current beam in the event.

[0113] In some embodiments, the event is used to trigger the terminal to report the first report.

[0114] In some embodiments, the event can include a trigger condition that the current beam and / or the candidate beam satisfies.

[0115] In some embodiments, the current beam can also be referred to as a serving beam. The candidate beam can also be referred to as a new beam, a target beam, a neighboring beam, etc.

[0116] In some embodiments, the terminal determines the first reference signal resource corresponding to the current beam in the event.

[0117] In some embodiments, the beam can also be referred to as: spatial Rx parameter, quasi co-location (QCL) type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, transmission configuration indicator state (TCI state), joint TCI state, downlink TCI state (DL TCI state), uplink TCI state (DL TCI state), unified TCI state, common TCI state, spatial relation information, etc. The beam can be replaced with any of the above.

[0118] In some embodiments, the first reference signal resource is a reference signal resource for beam measurement. That is, the terminal determines the first reference signal resource corresponding to the current beam, which is used for beam measurement.

[0119] In some embodiments, the first reference signal resource is at least one of the second reference signal resources, and the second reference signal resource is configured with TRS information.

[0120] In some embodiments, the second reference signal resource is determined based on an indicated TCI state of the network device.

[0121] In some embodiments, the terminal can determine the second reference signal resource based on the indicated TCI state. The indicated TCI state is a TCI state indicated by the network device to the terminal.

[0122] In some embodiments, the indicated TCI state is used to indicate the second reference signal resource. That is, the network device can directly indicate the second reference signal resource through the TCI state, and the terminal can take the indicated second reference signal resource as the first reference signal resource corresponding to the current beam for beam measurement.

[0123] 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).

[0124] For example, the network device activates one or more TCI states through the MAC CE, and the network device indicates one or more indicated TCI states through a code point in the DCI.

[0125] In some embodiments, the indicated TCI state can include at least one of the following: an indicated joint TCI state; an indicated downlink TCI state (DL TCI state); and an indicated uplink TCI state (UL TCI state).

[0126] In some embodiments, when the indicated TCI state indicates that the QCL Type A and the QCL Type D RSs are both the first CSI-RS configured with TRS information, the terminal can determine the reference signal resource corresponding to the first CSI-RS as the second reference signal resource for beam measurement. That is, the terminal can take the first CSI-RS configured with the TRS information as the second reference signal resource for beam measurement.

[0127] In some embodiments, the second reference signal resource includes one or more reference signal resources.

[0128] For example, the second reference signal resource (the reference signal resource configured with the TRS information) can belong to one or more reference signal resource sets. Each reference signal resource set can include one or more periodic reference signal resources, or include one or more aperiodic reference signal resources, or include one periodic reference signal resource set and one aperiodic reference signal resource set. For example, one reference signal resource set can include 2 or 4 periodic reference signal resources.

[0129] In some embodiments, the first reference signal resource includes at least one of the following: a reference signal resource determined by the terminal based on the one or more reference signal resources; a reference signal resource determined by the network device based on the one or more reference signal resources; a first reference signal resource in the one or more reference signal resources; a last reference signal resource in the one or more reference signal resources; a periodic reference signal resource in the one or more reference signal resources; an aperiodic reference signal resource in the one or more reference signal resources.

[0130] In some embodiments, the terminal determines the first reference signal resource, including at least one of the following: the terminal determines any one or more reference signal resources in the one or more reference signal resources as the first reference signal resource; the terminal determines one reference signal resource in the one or more reference signal resources as the first reference signal resource based on an indication of the network device; the terminal determines a first reference signal resource in the one or more reference signal resources as the first reference signal resource; the terminal determines a last reference signal resource in the one or more reference signal resources as the first reference signal resource; the terminal determines a periodic reference signal resource in the one or more reference signal resources as the first reference signal resource; the terminal determines an aperiodic reference signal resource in the one or more reference signal resources as the first reference signal resource.

[0131] For example, the terminal determines any one or more reference signal resources in the one or more reference signal resources in the second reference signal resource as the first reference signal resource for beam measurement. For example, the TCI state indicated by the network device is used to indicate the second reference signal resource, and the terminal determines any one or more reference signal resources in the one or more reference signal resources in the second reference signal resource indicated by the network device as the first reference signal resource. It can also be understood that the terminal can arbitrarily select one or more reference signal resources as the first reference signal resource for beam measurement based on its own implementation.

[0132] For example, the network device determines the first reference signal resource from one or more reference signal resources in the second reference signal resource, and indicates the first reference signal resource to the terminal. The terminal determines the first reference signal resource from the one or more reference signal resources based on the indication of the network device, and performs the beam measurement. That is, the network device can indicate the first reference signal resource to the terminal through explicit indication. The network device can indicate the first reference signal resource through RRC signaling and / or MAC CE; or the network device can indicate the first reference signal resource through indication information, which can be included in TCI state information.

[0133] For example, the terminal takes the first reference signal resource in the one or more reference signal resources in the second reference signal resource as the first reference signal resource, or takes the last reference signal resource as the first reference signal resource, for the beam measurement. The first reference signal resource can be the earliest reference signal resource in time in the second reference signal resource, i.e., the reference signal resource with the earliest symbol position in time domain. The last reference signal resource can be the last reference signal resource in time in the second reference signal resource, i.e., the reference signal resource with the latest symbol position in time domain. For example, the second reference signal resource includes 4 reference signal resources in 2 slots, and each slot includes two reference signal resources. Then, the first reference signal resource is the reference signal resource with the earliest symbol position in the slot at the front in time; and the last reference signal resource is the reference signal resource with the latest symbol position in the slot at the back in time.

[0134] For example, the terminal can take a periodic reference signal resource in the one or more reference signal resources in the second reference signal resource as the first reference signal resource, for the beam measurement. Further, the terminal can take the first or last reference signal resource in the periodic reference signal resource as the first reference signal resource.

[0135] For example, the terminal can take an aperiodic reference signal resource in the one or more reference signal resources in the second reference signal resource as the first reference signal resource, for the beam measurement. Further, the terminal can take the first or last reference signal resource in the aperiodic reference signal resource as the first reference signal resource.

[0136] The communication method provided by the embodiments of the present disclosure can ensure the reliability of the beam report triggered based on the trigger event.

[0137] Step S2102, when the trigger event is met, the terminal sends a first report to the network device.

[0138] In some embodiments, the network device receives the first report sent by the terminal.

[0139] In some embodiments, the first report may, for example, be a beam report, which can also be referred to as a beam measurement report.

[0140] In some embodiments, the first report is used to report reference signal resources and / or measurement results corresponding to the reference signal resources. The reference signal resources reported by the first report can include the first reference signal resources or other reference signal resources different from the first reference signal resources.

[0141] In some embodiments, the reference signal resources reported by the first report can include reference signal resources corresponding to the current beam and / or candidate beam.

[0142] In some embodiments, the first report includes at least one of the following: reference signal resource identification (RSID); Layer 1 reference signal receiving power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); capability index; power headroom; power backoff; uplink transmission power; event ID; TCI state ID.

[0143] In some embodiments, the reference signal resource identification included in the first report can include the identification of the first reference signal resource, or the identification of other reference signal resources.

[0144] In some embodiments, the identification of the first reference signal resource includes at least one of the following: synchronization signal block (SSB) identification; channel state information reference signal (CSI-RS) identification.

[0145] In some embodiments, the uplink transmission power may, for example, be the power headroom and / or the power backoff.

[0146] In some embodiments, the capability index can be the maximum number of supported SRS (Sounding Reference Signal) antenna ports.

[0147] In some embodiments, the event includes at least one of the following: the quality of the current beam is lower than a first threshold; the quality of the candidate beam is higher than a second threshold; the difference between the quality of the candidate beam and the quality of the current beam is higher than a third threshold.

[0148] In some embodiments, the quality of the beam can be L1-RSRP, L1-SINR, or uplink transmission power, which is not limited in the present disclosure.

[0149] In some embodiments, when the monitored current beam is a joint TCI state or a UL TCI state, and / or the monitored candidate beam is to be used for a joint TCI state or a UL TCI state, the quality of the beam can be the uplink transmission power.

[0150] 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.

[0151] In some embodiments, the terminal determines the reference signal resource corresponding to the candidate beam based on the configuration of the network device.

[0152] In some embodiments, the event can include the current beam or the candidate beam. When the event is triggered, the terminal can determine the reference signal resource corresponding to the candidate beam based on the configuration of the network device.

[0153] In some embodiments, the terminal can send a beam report to the network device when the event is triggered based on the event and the determined first reference signal resource.

[0154] In some embodiments, the terminal can determine the first reference signal resource corresponding to the current beam included in the event, then measure the first reference signal resource, and determine whether the trigger condition is met based on the measurement result of the first reference signal resource. When the measurement result meets the trigger condition in the event, the terminal sends a beam report to the network device.

[0155] The communication method provided in the embodiments of the present disclosure can determine at least one reference signal resource in the second reference signal resource configured with TRS information as the first reference signal resource corresponding to the current beam in the event, so as to determine whether the triggering event is triggered based on the accurate reference signal resource, and ensure the beam report accuracy; when the triggering event is met, the terminal sends the first report to the network device, and the timeliness of the beam report can be ensured.

[0203] In some embodiments, the terminal sends the first report to the network device when a trigger event is met.

[0204] In some embodiments, the network device receives the first report sent by the terminal.

[0205] In some embodiments, the reference signal resource reported in the first report can include reference signal resources corresponding to the current beam and / or candidate beam.

[0206] In some embodiments, the first report includes at least one of the following: reference signal resource identifier (RS ID); Layer 1 reference signal receiving power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); capability index; power headroom; power backoff amount (MPE: Power backoff); uplink transmission power (UL transmission power); event identifier (Event ID); TCI state ID.

[0208] 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.

[0209] In some embodiments, the terminal can determine a first reference signal resource corresponding to the current beam included in the event, and then measure the first reference signal resource, and determine whether the triggering condition is met based on the measurement result of the first reference signal resource. When the measurement result meets the triggering condition in the event, the terminal sends a beam report to the network device.

[0210] In some embodiments, the network device receives the first report sent by the terminal, and the network device can obtain accurate beam measurement results according to the first report reported by the terminal.

[0211] The optional implementation of step S5101 can refer to the other related parts of the embodiments of steps S2102 of Figure 2 , Figure 3 , Figure 4 step S4101 of Figure 2 , Figure 3 , Figure 4 and will not be repeated here.

[0212] In some embodiments, the above method can include the methods of the above embodiments of the communication system side, the terminal side, the network device side, etc., and will not be repeated here.

[0213] The communication method provided by the embodiments of the present disclosure is based on the UE-initiated beam reporting or the event-triggered beam reporting, the terminal determines TRS as the RS corresponding to the current beam, so that when the indicated TCI state indicates the RS configured only with the TRS, the terminal can explicitly trigger the RS corresponding to the current beam in the event, thereby guaranteeing the reliability of triggering the event.

[0214] 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 (also referred to as a triggering condition). The terminal sends a beam report when the triggering condition of the event is met based on the first reference signal resource and the event.

[0215] In some embodiments, the beam can be referred to as a beam, a spatial reception parameter (Spatial Rx parameter), a Quasi co-location (QCL) Type D, a spatial setting, a spatial reception filter, a spatial transmission filter, a spatial domain filter, a Transmission Configuration Indicator (TCI) state, a joint TCI state, a Downlink TCI state (DL TCI state), an Uplink TCI state (DL TCI state), a unified TCI state, a common TCI state, spatial relation information, etc. The beam can be replaced by any of the above.

[0216] In some embodiments, the terminal determines the first reference signal resource based on the indicated TCI state.

[0217] In some embodiments, the indicated TCI state can include an indicated joint TCI state, a DL TCI state, or an UL TCI state.

[0218] In some embodiments, when the indicated TCI state indicates that the RS of the QCL Type A and the QCL Type D are both the first CSI-RS configured with TRS information, the terminal determines that the first CSI-RS is the first reference signal resource. That is, the terminal takes the first CSI-RS configured with TRS information as the first reference signal resource for beam measurement.

[0219] In some embodiments, the TRS can correspond to one or more resource sets (resource sets). Each resource set includes 2 periodic resources or 4 periodic resources, or each resource set includes one periodic resource set and one aperiodic resource set.

[0220] In some embodiments, the terminal can determine which resource to measure based on at least one of the following methods:

[0221] Method 1: The terminal performs beam measurement based on TRS.

[0222] That is, based on the terminal implementation, it is not specified which resource to measure.

[0223] Method 2: The terminal performs beam measurement based on a default resource.

[0224] For example, the terminal can perform beam measurement based on the first resource.

[0225] For another example, the terminal can perform beam measurement based on the last resource.

[0226] Wherein, the first resource can be the first in time, and the last resource can be the last in time. Here, time refers to the time domain position of the resource.

[0227] Method 3: The terminal performs beam measurement based on a default resource.

[0228] For example, the terminal can perform beam measurement based on an aperiodic resource, or based on a periodic resource.

[0229] Wherein, method 2 and method 3 can be used independently, or in combination.

[0230] Method 4: The network device configures the terminal to perform beam measurement based on which resource.

[0231] That is, the network device explicitly indicates the terminal to perform beam measurement based on which resource.

[0232] In some embodiments, the beam report includes at least one of the following: RSID: SSBID, CSI-RSID; L1-RSRP; L1-SINR; Capability index: the maximum number of supported SRS port; Power headroom; MPE: Power backoff; UL transmission power: such as power headroom-power backoff; EventID; TCI state ID.

[0233] In some embodiments, the current beam can also be referred to as a serving beam.

[0234] In some embodiments, the event can include at least one of the following: the current beam quality is lower than a threshold; the candidate beam quality is higher than a threshold; the candidate beam quality is higher than the current beam quality by a threshold.

[0235] In some embodiments, the quality can be L1-RSRP, L1-SINR, or the quality can also be uplink transmission power.

[0236] When the monitored current beam is a joint TCI state or a UL TCI state, and / or the monitored candidate beam is intended to be used for a joint TCI state or a UL TCI state, the quality can be uplink transmission power.
