Uplink channel processing method, update method and related apparatus
[0001] This application claims priority to Chinese Patent Application No. 202510390526.3, filed on March 28, 2025, entitled "Uplink Channel Processing Method, Update Method and Related Apparatus", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of communication technology, and in particular to an uplink channel processing method, an update method, and related apparatus. Background Technology
[0003] Fifth-generation (5G) mobile communication systems can employ high-frequency communication, specifically ultra-high-frequency (UHF) signals (such as 28GHz) for data transmission. A major problem with high-frequency communication is the sharp decrease in signal energy with transmission distance, resulting in short transmission ranges. To overcome this, high-frequency communication uses analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a beam-like signal (called an analog beam, or simply a beam), thereby increasing the transmission distance. Both network devices and terminal devices utilize beamforming for transmission. Specific beamforming is required for uplink and downlink data transmission between network devices and terminal devices.
[0004] Network devices and terminal devices can select appropriate beams through a beam management process. Then, they communicate using these selected beams. The terminal device can also measure the signal quality of multiple beams configured for it by the network device. The terminal device then reports the signal quality of at least one beam with the best measured signal quality, based on the network's configured reporting resources. However, the reporting of measurement results is primarily determined by the network device, leading to significant uplink resource overhead. To address this, event-triggered measurement result reporting is proposed. When a corresponding event occurs, the terminal device reports the event-triggered measurement result, thereby reducing uplink resource overhead. Building on this, how to avoid unnecessary measurement result reporting to further reduce uplink resource overhead is a worthwhile consideration. Summary of the Invention
[0005] This application provides an uplink channel processing method, update method, and related apparatus, used to, when a first condition is met, cancel the transmission operation of the uplink control channel and / or the transmission operation of the first uplink data channel, or cancel the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel. This avoids unnecessary reporting of measurement results and reduces uplink resource overhead.
[0006] The first aspect of this application provides an uplink channel processing method, which can be used on the terminal side, for example, executed by a terminal device. The terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; specifically, this application does not limit the scope. It should be noted that, in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced by a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; specifically, this application does not limit the scope. In the first aspect and its possible implementations, the method is described as being executed by a terminal device. The method includes: a terminal device determining an uplink control channel, the uplink control channel being used to request scheduling a first uplink data channel for the terminal device, the first uplink data channel being used to carry the measurement result corresponding to a first event; or, the uplink control channel being used to notify a network device that the measurement result corresponding to the first event is carried on a second uplink data channel; when a first condition is met, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the first uplink data channel, or, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel; wherein, the first condition includes at least one of the following: during the transmission time of the uplink control channel, a first timer is counting down, and the terminal device is prohibited from reporting event-triggered measurement results during the counting duration of the first timer; within a first time window, the serving beam measurement resource of the terminal device changes; within a first time window, the new beam measurement resource of the terminal device changes; or, within a first time window, the threshold value corresponding to the first event is updated.
[0007] In the above technical solution, when a first event occurs or the number of times the first event occurs within a first time window is greater than or equal to a first threshold, the terminal device can send an uplink control channel to facilitate the terminal device reporting the measurement result corresponding to the first event. However, when a first condition is met, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the first uplink data channel, or the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel; wherein, the first condition includes at least one of the following: during the transmission time of the uplink control channel, a first timer is counting down, and the terminal device is prohibited from reporting event-triggered measurement results within the counting duration of the first timer; within the first time window, the serving beam measurement resources of the terminal device change; within the first time window, the new beam measurement resources of the terminal device change; or within the first time window, the threshold value corresponding to the first event is updated. Therefore, when the first condition is met, the terminal device can cancel the transmission of the uplink control channel and / or the uplink data channel, thereby avoiding unnecessary reporting of measurement results and reducing uplink resource overhead. For example, if the serving beam measurement resources of the terminal device change within the first time window, then the measurement results obtained before the change are meaningless to the network device. Therefore, the terminal device does not need to report this measurement result, thus avoiding unnecessary reporting. Similarly, if the new beam measurement resources of the terminal device change within the first time window, then the measurement results obtained before the change are meaningless to the network device. Therefore, the terminal device does not need to report this measurement result, thus avoiding unnecessary reporting. Furthermore, if the threshold value corresponding to the first event is updated within the first time window, before the threshold value corresponding to the first event is updated, the terminal device uses the threshold value before the update of the first event to determine whether to report the event-triggered measurement result. However, when the threshold value corresponding to the first event changes, the measurement results obtained before the update of the threshold value corresponding to the first event are meaningless to the network device. Therefore, it is unnecessary to report this measurement result, thus avoiding unnecessary reporting.
[0008] In the first aspect mentioned above, the change in the service beam measurement resources of the terminal device within the first time window can be alternatively described as: the service beam of the terminal device changes within the first time window; or, the transmission configuration indicator state (TCI-state) currently used or indicated by the terminal device changes within the first time window; or, the quasi-colocation (QCL) resources in the TCI state currently used or indicated by the terminal device change within the first time window; or, the synchronization signal and PBCH block (SSB) resources corresponding to the QCL resources in the TCI state currently used or indicated by the terminal device change within the first time window. The synchronization signal and PBCH block can also be referred to as the synchronization signal block (SSB).
[0009] In the first aspect mentioned above, the change of the new beam measurement resources of the terminal device within the first time window can be described as: the new beam of the terminal device changes within the first time window; or, the new beam measurement resources of the terminal device are updated within the first time window.
[0010] The second aspect of this application provides an uplink channel processing method, which can be used on the terminal side, for example, executed by a terminal device. The terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; specific details are not limited in this application. It should be noted that, in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced by a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; specific details are not limited in this application. In the second aspect and its possible implementations, the method is described using the example of execution by a terminal device. The method includes: a terminal device determining an uplink control channel, the uplink control channel being used to request scheduling a first uplink data channel for the terminal device, the first uplink data channel being used to carry the measurement result corresponding to the first event; or, the uplink control channel being used to notify the network device that the measurement result corresponding to the first event is carried on a second uplink data channel; when a third condition is met, the terminal device sends the uplink control channel and / or the first uplink data channel, or the terminal device sends the uplink control channel and / or the second uplink data channel; wherein, the third condition includes at least one of the following: during the transmission time of the uplink control channel, a first timer is not counting, and the terminal device is prohibited from reporting event-triggered measurement results within the counting duration of the first timer; within a first time window, the service beam measurement resources of the terminal device have not changed; within a first time window, the new beam measurement resources of the terminal device have not changed; or, within a first time window, the threshold value corresponding to the first event has not been updated.
[0011] In the above technical solution, when the first event occurs or the number of times the first event occurs within the first time window is greater than or equal to the first threshold, the terminal device determines the uplink control channel to facilitate the terminal device reporting the measurement result corresponding to the first event. Specifically, when the third condition is met, the terminal device sends the uplink control channel and / or the first uplink data channel, or the terminal device sends the uplink control channel and / or the second uplink data channel. The third condition includes at least one of the following: during the transmission time of the uplink control channel, the first timer is not counting, and the terminal device is prohibited from reporting event-triggered measurement results within the counting duration of the first timer; within the first time window, the service beam measurement resources of the terminal device have not changed; within the first time window, the new beam measurement resources of the terminal device have not changed; or, within the first time window, the threshold value corresponding to the first event has not been updated. Therefore, the terminal device reports the measurement result when the third condition is met. Ensuring the reporting of important measurement results is beneficial to ensuring communication transmission quality. Furthermore, it helps to avoid unnecessary reporting of measurement results and reduce uplink resource overhead.
[0012] In the second aspect mentioned above, the fact that the service beam measurement resources of the terminal device did not change within the first time window can be described as follows: the service beam of the terminal device did not change within the first time window; or, the TCI state currently used or indicated by the terminal device did not change within the first time window; or, the QCL resources in the TCI state currently used or indicated by the terminal device did not change within the first time window; or, the SSB resources corresponding to the QCL resources in the TCI state currently used or indicated by the terminal device did not change within the first time window.
[0013] In the second aspect mentioned above, the statement that the new beam measurement resources of the terminal device did not change within the first time window can be replaced by describing that: the new beam of the terminal device did not change within the first time window; or, the new beam measurement resources of the terminal device were not updated within the first time window.
[0014] Based on the first or second aspect, in one possible implementation, the first time window is the time interval between a first moment and a second moment, and the length of the first time window is L. The first moment is equal to the second moment minus L. The second moment is any one of the following: the transmission time corresponding to the uplink control channel; the time after subtracting the first time offset from the transmission time corresponding to the uplink control channel; the time of the last occurrence of the first event before the transmission time corresponding to the uplink control channel; the current time; the time of the first event; or the time of the first report of the channel state information (CSI) reference resource corresponding to the configuration. In this implementation, the length, start position, and end position of the first time window are defined. This facilitates the terminal device in determining whether to report event-triggered measurement results based on the first time window. Ensuring that the terminal device reports necessary measurement results is beneficial for ensuring communication transmission between the terminal device and the network device.
[0015] Based on the first or second aspect, in one possible implementation, the first time window is the time interval between a first moment and a second moment, and the length of the first time window is L.

In this implementation, the length, start position, and end position of the first time window are defined. This facilitates the terminal device in determining whether to report event-triggered measurement results based on the first event window. Ensuring that the terminal device reports necessary measurement results is beneficial for ensuring communication transmission between the terminal device and the network device.
[0016] Optionally, the current time refers to the time when the first event occurred, or the time when the first event last occurred before the transmission time corresponding to the uplink control channel, or the most recent time when the first event occurred.
[0017] The third aspect of this application provides an uplink channel processing method, which can be used on the terminal side, for example, executed by a terminal device.

In the third aspect and its possible implementations, the method is described as being executed by a terminal device.

[0018] In the above technical solution, when the first event occurs or the number of times the first event occurs within the first time window is greater than or equal to the first threshold, the terminal device determines the timing for transmitting the first uplink control channel, so that the terminal device can report the measurement result corresponding to the first event. However, when the first condition is met, the terminal device cancels the transmission operation of the first uplink control channel and / or the transmission operation of the first uplink data channel, or the terminal device cancels the transmission operation of the first uplink control channel and / or the transmission operation of the second uplink data channel. This avoids unnecessary reporting of measurement results and reduces uplink resource overhead.

[0028] In the above technical solution, the terminal device determines whether to report event-triggered measurement results based on the number of occurrences of the first event within the first time window. However, when a second condition is met, the first time window is updated to obtain a second time window. The terminal device then determines whether to report event-triggered measurement results based on the number of occurrences of the first event within the second time window. This condition-based update of the first time window helps avoid unnecessary measurement results from the terminal device and reduces uplink resource overhead.

The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.
[0127] A BBU includes at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.
[0128] In one possible implementation, as shown in Figure 2, the CU is a logical node carrying the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU can have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.
[0129] Optionally, as shown in Figure 2, the CU can be split into CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management (AMF) function in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. In the core network, network elements used to implement user plane functions, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; in practical applications, the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.
[0130] In one possible implementation, as shown in Figure 2, the DU is a logical node carrying the RLC layer, the medium or media access control (MAC) layer, the higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.
[0131] In one possible implementation, as shown in Figure 2, the RU is a logical node carrying both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a wireless link.
[0132] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Split user (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.
[0133] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.
[0134] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.
[0135] It should be noted that network devices can be devices or apparatuses with chips, or devices or apparatuses with integrated circuits, or chips, chip systems, modules, or control units in the devices or apparatuses shown above; this application does not impose any specific limitations. It should also be noted that in this application, the term "network device" can refer to the network device itself, or to chips, functional modules, or integrated circuits within the network device that implement the methods provided in this application; this application does not impose any specific limitations.
[0136] To facilitate understanding of the technical solutions of the embodiments of this application, the following, in conjunction with Figures 3 and 4, illustrates two possible communication systems to which the methods provided in the embodiments of this application are applicable.
[0137] Figure 3 is a schematic diagram of a communication system according to an embodiment of this application. As shown in Figure 3, the communication system includes at least one network device and at least one terminal device. For example, network device 311, terminal device 321, and terminal device 322 are shown in Figure 3. Network device 311 can transmit data with terminal device 321 and terminal device 322. The technical solution of this application can be executed between network device 311 and terminal device 321 or terminal device 322.
[0138] Figure 4 is another schematic diagram of the communication system according to an embodiment of this application. As shown in Figure 4, the communication system may include at least two network devices and at least one terminal device. For example, network devices 411, 412, 413, and terminal device 421 are shown in Figure 4. Terminal device 421 may be provided with communication services by multiple network devices. For example, as shown in Figure 4, network device 411 may transmit with terminal device 421, network device 412 may transmit with terminal device 421, and network device 413 may transmit with terminal device 421. That is, a terminal device may be provided with communication services by multiple network devices simultaneously. The technical solutions of this application can be implemented between terminal device 421 and network devices 411, 412, or 413.
[0139] To facilitate understanding of the technical solution of this application, some technical terms involved in this application will be introduced below.
[0140] 1. Beam: A beam is a communication resource. A beam can be wide, narrow, or other types of beams, and the technology used to form a beam can be beamforming technology or other techniques. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered different resources.
[0141] In the NR protocol, beaming can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. Beaming can be indicated by transmission configuration indicator state (TCI-state) parameters or by spatial relation parameters. Therefore, in this application, beaming can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (including uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. Beaming can also be replaced with other beaming terms, which are not limited herein.
[0142] The beam used to transmit signals can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be called a downlink beam. In this application, the transmission beam, downlink beam, channel state information reference signal (CSI-RS), TCI-State, downlink / joint transmission configuration indication state (DLorjointTCI state), synchronization signal and PBCH block (SSB), synchronization signal block (SSB), and tracking reference signal (TRS) can be interchanged.
[0143] The beam used to receive signals can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by any of the following: spatial relation, uplink TCI-state, or sounding reference signal (SRS) resource (indicating the transmit beam using that SRS). The receive beam can also be referred to as the uplink beam. In this application, the receive beam, uplink beam, uplink transmission configuration indication state (UL TCI-state), DLorjointTCI state, sounding reference signal (SRS), CSI-RS, SSB, and TRS can be interchanged.
[0144] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.
[0145] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal device provides feedback on the measured resource quality, allowing the network device to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the transmission configuration indication (TCI) field in downlink control information (DCI) to indicate beam information to the terminal device.
[0146] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and probe signals, etc. The one or more antenna ports forming a beam can also be considered as a set of antenna ports.
[0147] 2. Quasi-Co-location: Quasi-co-location indicates that multiple resources share one or more identical or similar communication characteristics. For multiple resources with quasi-co-location, identical or similar communication configurations can be used. For example, if two antenna ports have quasi-co-location, the large-scale channel characteristics of one port transmitting one symbol can be inferred from the large-scale channel characteristics of the other port transmitting one symbol. Large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receive parameters, terminal equipment receive beam number, transmit / receive channel correlation, receive angle of arrival, spatial correlation of receiver antennas, angel-of-arrival (AoA), average angle of arrival, AoA spread, etc. Specifically, this co-location indication is used to indicate whether at least two sets of antenna ports have a co-location relationship, including: the co-location indication indicating whether the channel state information reference signals transmitted by at least two sets of antenna ports originate from the same transmission point, or the co-location indication indicating whether the channel state information reference signals transmitted by at least two sets of antenna ports originate from the same beamgroup.
[0148] 3. TCI: Also known as TCI state. In both uplink and downlink transmission, correct beamforming is required for proper transmission between network devices and terminal devices. In downlink transmission, the network device needs to indicate its downlink transmit beam to the terminal device. The terminal device can then determine a suitable receive beam to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmit beam it uses to send information. The network device can determine the uplink transmit beam with better signal quality for the terminal device. Both uplink and downlink transmit beams can be indicated by their respective TCI states. Specifically, the downlink transmit beam can be indicated by the downlink TCI state, and the uplink transmit beam by the uplink TCI state.
[0149] In the 3GPP protocol, network devices can indicate the TCI status to terminal devices through the TCI field in the DCI (Digital Channel Identity). The TCI field is 3 bits in size and can be represented by 8 different field values (codepoints). Each field value of the TCI field can be associated with a TCI status identifier ID. This TCI status identifier can uniquely identify a TCI status, which can be a downlink TCI status or an uplink TCI status. Each field value of the TCI field can also be associated with two TCI status identifiers, which can uniquely identify two TCI statuses, including one downlink TCI status and one uplink TCI status.
[0150] The downlink TCI status includes several parameters that terminal devices can use to determine information related to the downlink transmit beam, thereby determining the appropriate receive beam to receive information from the network device. The TCI status is configured by the network device for each terminal device, and the structure of the downlink TCI status is shown below:
[0151] Each TCI state includes its own identifier (tci-StateId) and two quasi-colocation information (QCL-info) entries. Each QCL-info entry includes a reference signal resource, indicating that downlink transmission for that TCI state should use the same downlink timing, frequency offset, or receive beam as that reference signal resource. This is determined by the type of the QCL-info entry. The QCL type can have four values: {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB, or typeC, downlink transmission should use the same downlink timing and frequency offset as that reference signal resource. When the QCL type is typeD, downlink transmission should use the same receive beam as that reference signal resource. Of the two QCL-info entries mentioned above, one is typeD, and the other is typeA, typeB, or typeC. The terminal device can determine which receive beam to use to receive the corresponding downlink transmission by using the typeD QCL-info entry. The specific execution steps are as follows:
[0152] Network devices indicate a specific downlink TCI state to terminal devices via DCI. The terminal device identifies a reference signal resource in the QCL information for this downlink TCI state (type D). The terminal device then uses the receive beam of this reference signal resource as the receive beam for downlink transmission. It should be noted that the receive beam of this reference signal resource is obtained by the terminal device in advance through a beam management process. Through this beam management process, the terminal device can determine which receive beam is optimal for receiving the reference signal resource and select that beam as the receive beam for that reference signal resource.
[0153] The uplink TCI state includes a reference signal resource, which indicates that uplink transmissions using this TCI state should employ the same uplink transmit beam as the reference signal resource. The terminal device can determine which transmit beam to use for uplink transmission by using this reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info and does not distinguish between QCL types, because it does not need to reference uplink timing and frequency offset information; only the uplink transmit beam needs to be referenced. The structure of the uplink TCI state is as follows:
[0154] The specific execution steps are as follows:
[0155] Network devices indicate a specific uplink TCI state to terminal devices via DCI. The terminal device then determines the reference signal resource within that uplink TCI state. The terminal device uses the transmission beam of this reference signal resource as its uplink transmission beam. It should be noted that the transmission beam of this reference signal resource is obtained by the terminal device in advance through a beam management process.
[0156] The following describes the configuration, activation, and indication of TCI status.
[0157] TCI-state configuration: Network devices configure multiple TCI-states to terminal devices via RRC signaling. Each of these TCI-states includes a QCL-Info of type type D. Network devices can also configure TCI-states that do not include a QCL-Info of type type D; however, these TCI-states are not used for data transmission beam indication and will not be discussed further here.
[0158] TCI-state activation: After configuring multiple TCI-states on a network device, eight of them need to be activated via a medium access control element (MAC CE). These eight TCI-states correspond one-to-one with the eight values of the TCI field in the DCI. That is, which eight TCI-states correspond to the eight values of the DCI's TCI field is determined by the MAC CE. The medium access control element (MAC CE) can also be called a media access control element.
[0159] TCI Status Indication: Network devices indicate a specific TCI-state through the TCI field in the DCI. For example, if the TCI field value in the DCI sent by the network device to the terminal device is 000, it indicates that the data transmission beam uses the TCI state corresponding to 000. The reference signal contained in the type D QCL-Info within this TCI state is the channel state information-reference signal (CSI-RS) with index #1, indicating that the beam used for data transmission is the same as the receiving beam corresponding to CSI-RS with index #1. The receiving beam corresponding to CSI-RS with index #1 can be determined through beam measurement procedures and is known to the terminal device. Therefore, by using the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam and thus use the appropriate beam to send or receive data.
[0160] It should be noted that the three description methods of TCI state, TCI-state, and TCI status in this article are interchangeable. In this article, ID can be an abbreviation of any of the following: identifier, indication, indicator, index, identity, and identification. These terms are interchangeable.
[0161] In this application, TCI can be translated as Transmission Configuration Indicator or Transmission Configuration Number. The English translation of Transmission Configuration Indicator is either "transmission configuration indicator" or "transmission configuration indication."
[0162] Currently, terminal devices and network devices select appropriate beams through a beam management process and communicate using those beams. The beam management process includes: first, coarse beam alignment based on the SSB (Solar Signal Block), and then fine beam adjustment based on the CSI-RS (Cyber-Independent Signaling System). The beam management process can be divided into three stages, which are described below.
[0163] Phase 1: Coarse beam alignment between network devices and terminal devices.
[0164] The base station performs beam scanning. Specifically, as shown in Figure 5a, the base station transmits SSBs to the terminal device at different times using beams from different directions. Simultaneously, the terminal device scans and receives the receiving beams; that is, the terminal device also receives SSBs from the network device at different times using beams from different directions. The terminal device determines the optimal beam for base station signal transmission and the optimal beam for terminal device signal reception based on the received signal strength. The beam used for base station signal transmission is simply called the base station beam, and the beam used for terminal device signal reception is simply called the terminal beam.
[0165] Specifically, the base station beam includes Terminal beams include As shown in Figure 5b, the base station sends SSB resource configuration information and reports resource configuration information to the terminal device. The base station beam includes beams B0 to B5, i.e., M=5. The terminal beam includes beams U0 to U3, i.e., N=4. The base station uses beam B0 to send SSBs to the terminal device through the corresponding SSB resources, uses beam B1 to send SSBs to the terminal device, and so on, using beam B5 to send SSBs to the terminal device. The terminal device measures the SSBs sent by the base station through beams B0 to B5 respectively through beams U0 to U3, and obtains the measurement results. The terminal device can determine the base station beam with better or better signal quality based on the measurement results. The terminal device feeds back the base station beam with better or better signal quality to the network device. It should be noted that in Phase 1, both the base station beam and the terminal beam can be understood as wide beams.
[0166] Phase Two: Base Station Beam Fine-Tuning.
[0167] The base station determines multiple first candidate beams based on the base station beam with the best or better signal quality determined in Phase 1. Each first candidate beam is a narrow beam. Specifically, as shown in Figure 6a, these multiple first candidate beams include beams S0 to S2. For example, beam B3 is determined in Phase 1 above. This beam B3 is a wide beam, and the base station determines beams S0 to S2 through beam B3. The terminal device determines the better terminal beam as beam U1 based on the above Phase 1. As shown in Figure 6b, the base station sends CSI-RS configuration information to the terminal device. The network device uses beam S0 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, uses beam S1 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, and uses beam S2 to send CSI-RS to the terminal device through the corresponding CSI-RS resources. The terminal device receives the CSI-RS sent by the base station through different beams through beam U1 and obtains the measurement results. The terminal device can determine the candidate beam with the best or better signal quality based on the measurement results. The terminal device feeds back the first candidate beam with the better or best signal quality to the network device. For example, as shown in Figure 6c, the first candidate beam with the better or best signal quality is beam S1. The base station uses this first candidate beam with the better or best signal quality as the beam for communication with the terminal device.
[0168] Phase 3: UE beam fine-tuning.
[0169] The base station transmits CSI-RS to the terminal device using beam S1. The terminal device determines the optimal terminal beam as beam U1 through Phase 1. Beam U1 is a wide beam. The terminal device determines multiple second candidate beams through beam U1, as shown in Figure 6c. These second candidate beams include beams P1 to P4. The terminal device receives the CSI-RS transmitted by the base station through beam S1 via beams P1 to P4, obtaining the measurement results. Based on the measurement results, the terminal device can select one beam from beams P1 to P4 and use this beam as the beam for communication with network devices.
[0170] Network devices can be configured to allow terminal devices to report measurement results using one of three methods: periodic reporting, semi-persistent reporting, and aperiodic reporting. Semi-persistent reporting is also known as semi-static reporting.
[0171] Periodic Reporting: The network device sends reference signal resource configuration information to the terminal device. This reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device with periodic measurement reference signals. The terminal device can periodically measure the reference signals based on this reference signal resource configuration information and periodically report the measurement results. Optionally, the measurement results obtained from the terminal device's periodic measurement reference signals can be carried on physical uplink control channel (PUCCH) resources.
[0172] Semi-persistent reporting: The terminal device periodically measures the reference signal, but reports the measurement results using a semi-persistent reporting method. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. This information includes periodic reference signal resources. The network device configures the terminal device's periodic measurement reference signal. When the terminal device receives an activation signaling message (e.g., MAC CE, or DCI) from the network device, it can continuously report the measurement results. Alternatively, the network device can send a deactivation command to the terminal device to deactivate its semi-persistent reporting process. In another possible implementation, both the measurement of the reference signal and the reporting of the measurement results are semi-persistent. When the terminal device receives an activation signaling message from the network device, it continuously measures the reference signal and reports the measurement results. When the terminal device receives a deactivation command from the network device, it stops reporting the measurement results. Furthermore, the measurement results can be carried on PUCCH resources or Physical Uplink Shared Channel (PUSCH) resources.
[0173] Aperiodic reporting: When the terminal device receives a trigger command (e.g., DCI) from the network device, the terminal device measures a reference signal and reports the measurement result. After completing the reporting, the terminal device stops reporting the measurement result. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement result is carried on the PUSCH resource.
[0174] As described in the beam management process above, network devices and terminal devices can select suitable beams through beam management. Then, they communicate using the selected beams. The terminal device can also continue to measure the signal quality of multiple beams configured for it by the network device. Then, the terminal device reports the signal quality of at least one beam with the best measured signal quality, based on the network's configured reporting resources. Prior to R18, the network device held the dominant power in the terminal device's measurement result reporting process, deciding when to report the measurement results. This resulted in significant uplink resource overhead. For example, in periodic and semi-persistent reporting, the terminal device needed to report measurement results every cycle, which might be meaningless to the network. For instance, two reported measurement results might be identical (e.g., the optimal beam remained unchanged), thus wasting uplink resources. In R19, event-triggered reporting was introduced, allowing the terminal device to report beam measurement results related to the event, thereby reducing uplink resource overhead. Based on this, how to avoid unnecessary reporting of measurement results in order to further reduce uplink resource overhead is a question worth considering.
[0175] In this application, an event refers to an event related to a UE-initiated report, an event related to a measurement result report initiated by the terminal device, an event related to a report (or measurement result) after the terminal device actively performs a measurement, or an event related to specific conditions for a measurement result report initiated by the terminal device. For example, the terminal device may actively perform measurements (such as beam measurements or channel measurements) to obtain measurement results related to the event. Another example is that the terminal device may perform measurements based on reference signals according to the configuration of reference signal resources to obtain measurement results related to the event. Yet another example is that the terminal device actively performs measurements and reports the measurement results related to the event when specific conditions are met. Yet another example is that the terminal device measures the reference signal associated with the event to obtain measurement results, and then the terminal device determines whether to report the measurement results to the network device based on the measurement results. The terminal device can determine whether specific conditions are met or whether an event has occurred; if so, the terminal device reports the corresponding measurement results. The event can also be referred to as any of the following: triggering event, layer 1 (L1) triggering event, channel state information (CSI) measurement reporting triggering event, beam measurement reporting triggering event, L1 CSI reporting triggering event, L1 beam measurement reporting triggering event, etc. The naming of these events is not limited in this application embodiment. The event-triggered report or report can be referred to as any of the following: event-related report or report, event-triggered or UE-initiated report or report, event-triggered or UE-initiated beam report or report, event-triggered or UE-initiated CSIreport, event-triggered or UE-initiated beam measurement result report, event-triggered or UE-initiated interference measurement report, interference measurement report, CSIreport, beam measurement result report, etc.
[0176] In this application, the signal quality can optionally be reference signal received power (RSRP), signal to interference plus noise ratio (SINR), layer 1 reference signal received power (L1-RSRP), layer 1 signal to interference plus noise ratio (L1-SINR), synchronization signal reference signal received power (SS-RSRP), channel state information reference signal received power (CSI-RSRP), synchronization signal signal-to-interference-plus-noise ratio (SS-SINR), or channel state information signal-to-interference plus noise ratio (CSI-SINR). This application does not impose any specific limitations on the type of signal quality.
[0177] In this application, the serving beam can also be referred to as: TCI state, serving beam measurement resource, reference signal resource, beam measurement resource, measurement resource, resource corresponding to the serving beam, or measurement resource corresponding to the serving beam, etc., and this application does not limit the specific terminology. Similarly, the new beam can also be referred to as: TCI state, new beam measurement resource, reference signal resource, beam measurement resource, measurement resource, resource corresponding to the new beam, or measurement resource corresponding to the new beam, etc., and this application does not limit the specific terminology.
[0178] In this application, "timer is counting down" means that the timer is counting down within the set duration, or that the timer started counting from 0 and is currently counting down.
[0179] In this application, the reporting triggering methods include Mode A and Mode B. That is, the terminal device can report measurement results through either Mode A or Mode B. Mode A and Mode B are described below. It should be noted that Mode A can also have other names, such as Reporting Triggering Method One. Mode B can also have other names, such as Reporting Triggering Method Two.
[0180] I. Mode A includes the following steps a to c.
[0181] Step a: The terminal device sends an uplink control channel to the network device. This uplink control channel is used to request the network device to schedule a first uplink data channel for the terminal device. Alternatively, this uplink control channel is used to request the network device to schedule a first uplink data channel. Accordingly, the network device receives the uplink control channel. For example, the uplink control channel is PUCCH.
[0182] Optionally, the terminal device sends an uplink control channel to the network device when an event occurs or the conditions for the event are met. For example, as shown in Figure 7, when a first event occurs, or when the number of times the first event occurs within a first time window is greater than or equal to a first threshold, the terminal device sends an uplink control channel to the network device.
[0183] Step b: The network device sends the first scheduling signaling to the terminal device. Correspondingly, the terminal device receives the first scheduling signaling from the network device.
[0184] The first scheduling signaling is used to schedule the transmission of the first uplink data channel. Alternatively, the first scheduling signaling is used to indicate or schedule the first uplink data channel. Optionally, the first scheduling signaling is a DCI (Distributed Control Information). For example, as shown in Figure 7, the network device sends a DCI to the terminal device.
[0185] Optionally, the first uplink data channel is the first PUSCH.
[0186] Step c: The terminal device sends a first uplink data channel to the network device. Correspondingly, the network device receives the first uplink data channel from the terminal device.
[0187] As shown in Figure 7, the terminal device sends the first uplink data channel to the network device, and the first uplink data channel carries the measurement results.
[0188] II. Mode B includes the following steps 1 to 2.
[0189] Step 1: The terminal device sends an uplink control channel to the network device. This uplink control channel is used to notify the network device that the terminal device will send the measurement result corresponding to the first event through the second uplink data channel. Alternatively, this uplink control channel is used to notify the network device that the terminal device will send the measurement result corresponding to the first event through the second uplink data channel. Accordingly, the network device receives the uplink control channel from the terminal device.
[0190] Optionally, the terminal device sends an uplink control channel when an event occurs or the conditions for the event are met. For example, as shown in Figure 8, when a first event occurs, or when the number of times the first event occurs within a first time window is greater than or equal to a first threshold, the terminal device sends an uplink control channel to the network device.
[0191] Optionally, the uplink control channel is PUCCH.
[0192] Step 2: The terminal device sends a second uplink data channel to the network device. Correspondingly, the network device receives the second uplink data channel from the terminal device.
[0193] For example, the terminal device sends a second uplink data channel to the network device. The second uplink data channel carries the measurement results.
[0194] Optionally, the second uplink data channel is a pre-configured uplink channel. For example, the second uplink data channel is a pre-configured PUSCH. For example, the second uplink data channel is a pre-configured, un-scheduled PUSCH (CG-PUSCH).
[0195] The technical solution of this application is described below with reference to specific embodiments.
[0196] Figure 9 is a schematic diagram of an embodiment of the communication method of this application. Referring to Figure 9, the method includes:
[0197] 901. The terminal equipment determines the uplink control channel.
[0198] Specifically, the terminal device measures one or more measurement resources to obtain the measurement result corresponding to the first event. Alternatively, the terminal device measures the reference signal corresponding to one or more measurement resources to obtain the measurement result corresponding to the first event. Here, the one or more measurement resources are measurement resources associated with the terminal device's first reporting configuration. This first reporting configuration is associated with the first event. For more information on the first reporting configuration, please refer to the relevant description in step 900a below. When the first event occurs, or when the number of times the first event occurs within the first time window is greater than or equal to a first threshold, the terminal device can determine the uplink control channel so that the terminal device can report the measurement result corresponding to the first event through the uplink control channel. It should be noted that the first threshold is predefined, specified by the communication protocol, reported by the terminal device, or configured by the network device for the terminal device; this application does not specifically limit its definition. For information on the one or more measurement resources, the first event, the measurement result corresponding to the first event, and the first time window, please refer to the relevant description below.
[0199] In one possible implementation, the uplink control channel is used to request the scheduling of a first uplink data channel for the terminal device. The first uplink data channel carries the measurement results corresponding to the first event. In this implementation, the first reporting configuration is associated with mode A. Therefore, the terminal device adopts the reporting triggering method of mode A. When the first event occurs, the terminal device can send an uplink control channel to request the network device to schedule an uplink data channel for reporting the measurement results corresponding to the first event.
[0200] In another possible implementation, the uplink control channel is used to notify the network device that the measurement result corresponding to the first event is carried on the second uplink data channel. In this implementation, the first reporting configuration is associated with mode B. Therefore, the terminal device adopts the reporting triggering method of mode B. When the number of times the first event occurs within the first time window is greater than or equal to the first threshold, the terminal device can send an uplink control channel to inform the network device that the terminal device will send the measurement result corresponding to the first event on the second uplink data channel.
[0201] The reference signal corresponding to the one or more measurement resources can be understood as a reference signal carried on the one or more measurement resources. The one or more measurement resources include at least one of the following: a serving beam measurement resource of the terminal device, a first active beam measurement resource of the terminal device, or a new beam measurement resource of the terminal device. For example, the one or more measurement resources include the serving beam measurement resource of the terminal device and the new beam measurement resource of the terminal device. As another example, the one or more measurement resources include the first active beam measurement resource of the terminal device and the new beam measurement resource of the terminal device.
[0202] The serving beam is the beam currently used for transmission by the terminal device and the network device. Optionally, the serving beam is the beam corresponding to the TCI state indicated by the network device to the terminal device. Alternatively, the serving beam is the beam corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device, or the serving beam is the beam corresponding to the SSB resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device. The SSB resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device can be understood as an SSB resource that has a QCL relationship with that QCL resource. For example, the SSB resource is the source QCL resource in the QCL chain, and the source QCL resource is an SSB resource. The QCL chain is determined based on the QCL resources in the TCI state indicated by the network device to the terminal device. For example, the QCL resource in the TCI state indicated by the network device to the terminal device is a CSI-RS resource. The QCL resource in the TCI state corresponding to this CSI-RS resource is a TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as the TCI state used by the network device to send the CSI-RS resource, or the TCI state used by the network device to send the CSI-RS resource corresponding to the CSI-RS resource. The QCL resource in the TCI state corresponding to the TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as the TCI state used by the network device to send the TRS resource, or the TCI state used by the network device to send the TRS resource corresponding to the TRS resource. Therefore, the QCL resources (such as CSI-RS resources) in the TCI state indicated by the network device to the terminal device, the QCL resources (such as TRS resources) in the TCI state corresponding to the CSI-RS resource, and the QCL resources (such as SSB resources) in the TCI state corresponding to the TRS resource constitute a QCL chain. The source QCL resource of this QCL chain is an SSB resource. That is, the SSB resource associated with the QCL resource in the TCI state indicated by the network device to the terminal device. The first active beam is one of the beams activated by the network device for the terminal device.
[0203] In one possible implementation, the new beam is a beam of the terminal device other than the serving beam. Alternatively, the new beam is a beam of the terminal device that differs from the serving beam. For example, the new beam can be understood as a candidate beam of the terminal device. For example, the new beam is the beam corresponding to a TCI state other than the TCI state indicated to the terminal device in the TCI states configured by the network device for the terminal device. For another example, the new beam is the beam corresponding to a TCI state other than the TCI state indicated to the terminal device in the TCI states activated by the network device for the terminal device. For yet another example, the new beam can be the beam corresponding to a new beam measurement resource configured by the network device for the terminal device. The serving beam and the new beam are configured by the network device for the terminal device for the same measurement reporting process or the same reporting configuration. The measurement resources corresponding to the serving beam and the new beam can be configured in the same resource set or the same resource configuration. For example, the terminal device measures the serving beam and the new beam, or in other words, the terminal device measures the reference signal on the measurement resource corresponding to the serving beam and the reference signal on the measurement resource corresponding to the new beam. The measurement resource type corresponding to the serving beam is the same as the measurement resource type corresponding to the new beam. The terminal equipment measures both the serving beam and the new beam. The resource type corresponding to the serving beam is the same as the resource type corresponding to the at least one new beam. For example, the measurement resource corresponding to the serving beam is an SSB resource, and the measurement resource corresponding to the new beam is an SSB resource. Another example is that the measurement resource corresponding to the serving beam is a CSI-RS resource, and the measurement resource corresponding to the new beam is a CSI-RS resource.
[0204] In another possible implementation, the new beam is a beam of the terminal device other than the first active beam. In other words, the new beam is a beam of the terminal device that is distinct from the first active beam. For example, the new beam could be a beam activated by the network device for the terminal device other than the first active beam. Optionally, the first active beam can be the serving beam of the terminal device, or it can be a non-serving beam. When the network device indicates that the first active beam is the serving beam of the terminal device, then the first active beam is the serving beam.
[0205] Optionally, the uplink control channel is PUCCH. Optionally, the first uplink data channel is the first PUSCH. The second uplink data channel is the second PUSCH.
[0206] Optionally, the first event includes at least one of the following:
[0207] 1. The signal quality of the service beam of the terminal equipment is lower than the first threshold.
[0208] It should be noted that "lower than" means "less than", or "less than or equal to".
[0209] Optionally, the first threshold value may be predefined, specified by the communication protocol, or configured by the network device; this application does not specify the exact value.
[0210] 2. There exists at least one new beam with a signal quality higher than the serving beam's signal quality, and / or, the signal quality of the at least one new beam is higher than the serving beam's signal quality by a second threshold value. For example, the difference between the signal quality of at least one new beam and the serving beam is greater than the second threshold value. Alternatively, the difference between the signal quality of at least one new beam and the serving beam is greater than or equal to the second threshold value.
[0211] Optionally, the second threshold value may be predefined, specified by the communication protocol, or configured by the network device; this application does not specify the exact value.
[0212] 3. There exists at least one new beam whose signal quality is higher than that of the first active beam, and / or, the signal quality of at least one new beam is higher than that of the first active beam by a third threshold value. For example, the difference between the signal quality of at least one new beam and the signal quality of the first active beam is greater than the third threshold value. Or, the difference between the signal quality of at least one new beam and the signal quality of the first active beam is greater than or equal to the third threshold value.
[0213] Optionally, the third threshold value may be predefined, specified by the communication protocol, or configured by the network device; this application does not specify the exact value.
[0214] The first event mentioned above is merely an example; there are many other events that may be included as first events, but this application does not limit them.
[0215] The measurement result corresponding to the first event refers to the measurement result including the signal quality or channel state information of the measurement resources related to the first event. For example, if the first event is that the signal quality of the serving beam of the terminal device is lower than a first threshold, then the measurement result corresponding to the first event includes the signal quality of the serving beam. As another example, if there exists at least one new beam with a signal quality higher than the serving beam's signal quality, and the signal quality of the at least one new beam is higher than the serving beam's signal quality by a second threshold, then the measurement result corresponding to the first event may include the signal quality of the at least one new beam.
[0216] Optionally, the measurement results corresponding to the first event may include parameters characterizing the signal quality of the reference signal, such as RSRP and / or SINR. Alternatively, the measurement results corresponding to the first event may include parameters characterizing the downlink channel state, such as the channel quality indicator (CQI), precoding matrix indicator (PMI), and / or rank indicator (RI). The specific content included in the measurement results corresponding to the first event is determined based on the reporting content in the first reporting configuration. Please refer to the relevant description below for information on the reporting content in the first reporting configuration.
[0217] Optionally, the uplink control channel is a periodic uplink control channel. This periodic control channel includes multiple uplink control channel transmission opportunities. Specifically, the uplink control channel in step 901 can be understood as one transmission opportunity within the periodic control channel.
[0218] The first time window is the time interval between the first moment and the second moment. The length of the first time window is L. The first moment is equal to the second moment minus L. It should be noted that the length of the first time window can be predefined, specified by the communication protocol, or configured by the network device; this application does not limit this. For example, the length of the first time window can be several time slots or dozens of time slots. For example, as shown in Figure 10, the first time window is the time interval between time t1 and time t2. The first time window is represented as [t1, t2], (t1, t2), [t1, t2), or (t1, t2). The following describes some possible implementations of the second moment.
[0219] 1. The second moment is the transmission time corresponding to the uplink control channel. Alternatively, the second moment is the transmission time corresponding to a transmission opportunity of the uplink control channel. For example, as shown in Figure 7, the transmission time corresponding to this uplink control channel is the time domain position occupied by the uplink control channel in the time domain. For example, the uplink control channel occupies time domain symbol 1 in time slot 0, and the second moment is time domain symbol 3 in time slot 0.
[0220] 2. The second time point is the time after subtracting the first time offset from the transmission time corresponding to the uplink control channel. Alternatively, the second time point is the time after subtracting the first time offset from the transmission time of the transmission opportunity corresponding to the uplink control channel. For example, as shown in Figure 7, the transmission time corresponding to the uplink control channel is time-domain symbol 3 in time slot 0, and the first time offset is two time-domain symbols; therefore, the second time point is time-domain symbol 1 in time slot 0.
[0221] It should be noted that the first time offset is predefined, either as specified by the communication protocol or configured by the network device; this application does not impose any specific restrictions on it.
[0222] 3. The second time point is the time when the first event last occurred before the transmission time corresponding to the uplink control channel. For example, as shown in Figure 7, the transmission time corresponding to the uplink control channel is the time domain position occupied by the uplink control channel in the time domain. For example, the uplink control channel occupies time domain symbol 1 in time slot 0, which means the second time point is the time when the first event last occurred before time domain symbol 1 in time slot 3. In other words, the second time point is the time when the first event occurred.
[0223] 4. The second moment is the current time. The current time refers to the time when the first event occurred, or the time when the first event last occurred before the transmission time corresponding to the uplink control channel, or the most recent time when the first event occurred.
[0224] 5. The second moment is the time when the CSI reference resource corresponding to the first reported configuration is configured.
[0225] The first reported configuration corresponds to a CSI reference resource, which serves as a reference time for CSI measurement. For example, the terminal device only measures reference signal resources preceding this CSI reference resource. The time corresponding to this CSI reference resource refers to its time-domain location.
[0226] Optionally, the CSI reference resource is determined based on the reporting time of the measurement results corresponding to the first reporting configuration.
[0227] Therefore, the terminal device determines the second moment, and the length of the first time window is L. Thus, the terminal device can determine the start time of the first time window, i.e., the first moment. In this implementation, the length, start position, and end position of the first time window are defined. This facilitates the terminal device's decision on whether to report event-triggered measurement results based on the first event window. Ensuring that the terminal device reports necessary measurement results is beneficial for guaranteeing communication and transmission between the terminal device and network devices.
[0228] Optionally, the uplink control channel is a periodic uplink control channel. The periodic control channel includes multiple uplink control channel transmission opportunities. Specifically, the uplink control channel in step 901 above can be understood as one uplink control channel transmission opportunity within the periodic control channel.
[0229] Optionally, the embodiment shown in FIG9 further includes step 901a. Step 901a may be performed before step 901.
[0230] 901a. The terminal device measures one or more measurement resources to obtain the measurement result corresponding to the first event.
[0231] Step 901a above can be alternatively described as: the terminal device measures a reference signal carried on one or more measurement resources; or, the terminal device measures a reference signal corresponding to the one or more measurement resources.
[0232] Optionally, the embodiment shown in FIG9 further includes step 900a, which may be performed before step 901.
[0233] 900a. The network device sends the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.
[0234] The first configuration information indicates the first reporting configuration. Optionally, the first configuration information includes the first reporting configuration. The first reporting configuration includes the reporting content and / or reporting method of the measurement results corresponding to the first reporting configuration. For example, the reporting content includes parameters characterizing the signal quality of the reference signal, such as RSRP or SINR. Alternatively, the reporting content includes parameters characterizing the downlink channel state, such as CQI, PMI, RI, etc. For example, the reporting method includes aperiodic reporting or periodic reporting.
[0235] It should be noted that the first configuration information can indicate one or more reported configurations. This application does not limit the specifics, but the first reported configuration will be used as an example for introduction.
[0236] Optionally, the first configuration information may also indicate at least one of the following: one or more measurement resources associated with the first reporting configuration, a first event associated with the first reporting configuration, a reporting trigger mode associated with the first reporting configuration, or a reporting mode associated with the first reporting configuration. For example, the first configuration information may include at least one of the following: one or more measurement resources associated with the first reporting configuration, a first event associated with the first reporting configuration, a reporting trigger mode associated with the first reporting configuration, or a reporting mode associated with the first reporting configuration. It should be noted that other information besides the first reporting configuration in the first configuration information may also be carried within other information, and this application does not limit the specific details.
[0237] Here, the one or more measurement resources belong to one or more resource configurations. In other words, the first reporting configuration is associated with one or more resource configurations. Please refer to the previous sections for information on the first event and reporting trigger modes.
[0238] The reporting modes include Reporting Mode 1 or Reporting Mode 2. Reporting Mode 1 means that the terminal device can report event-triggered measurement results as soon as the first event occurs. That is, the terminal device can report event-triggered measurement results when the conditions for an event occurrence are met. Reporting Mode 2 means that the terminal device reports event-triggered measurement results only when the number of times the first event occurs within the first time window is greater than or equal to a first threshold, or the terminal device only reports event-triggered measurement results at this time.
[0239] Optionally, the embodiment shown in Figure 9 further includes step 900b. Step 900b may be performed before step 901.
[0240] 900b. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.
[0241] The capability information includes at least one of the following: whether the terminal device supports reporting event-triggered measurement results; or the reporting triggering modes supported by the terminal device. Please refer to the aforementioned introduction regarding reporting triggering modes.
[0242] It should be noted that if the embodiment shown in Figure 9 further includes step 900a, step 900b can be performed before step 900a.
[0243] 902. When the first condition is met, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the first uplink data channel, or the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel.
[0244] The first condition includes at least one of the following:
[0245] 1. During the transmission time of the uplink control channel, the first timer is counting down. During the duration of the first timer, terminal devices are prohibited from reporting event-triggered measurement results. Please refer to the aforementioned introduction regarding the transmission time of the uplink control channel; it will not be repeated here.
[0246] Specifically, after the terminal device reports the measurement results to the network device, it can start a first timer. During the duration of this first timer, the terminal device is prohibited from reporting measurement results again. If the first timer is already running during the uplink control channel transmission time, the terminal device cannot report measurement results. This helps avoid unnecessary measurement result reporting and reduces uplink resource overhead.
[0247] Second, within the first time window, the service beam measurement resources of the terminal equipment change. Please refer to the aforementioned introduction regarding the first time window; it will not be repeated here.
[0248] Optionally, within the first time window, a change in the service beam measurement resources of the terminal device can be described as any of the following:
[0249] 1. Within the first time window, the service beam of the terminal device changes.
[0250] 2. Within the first time window, the TCI status currently used or indicated by the terminal device changes.
[0251] In the first and second items above, the terminal device receives first indication information from the network device. This first indication information is used to re-indicate or update the TCI state used by the terminal device. The TCI state indicated by this first indication information is different from the TCI state used by the terminal device before receiving the first indication information. That is, the TCI state currently used or indicated by the terminal device has changed.
[0252] 3. Within the first time window, the QCL resources in the TCI state currently used or indicated by the terminal device change. For example, the terminal device receives second indication information. The second indication information is used to update the QCL resources in the TCI state currently used or indicated by the terminal device. The TCI state indicated by the second indication information may be the same as the TCI state used by the terminal device before receiving the second indication information, but the QCL resources in the TCI state indicated by the second indication information are different from the QCL resources in the TCI state used by the terminal device before receiving the second indication information.
[0253] 4. Within the first time window, the SSB resource corresponding to the QCL resource in the TCI state currently used or indicated by the terminal device changes. For example, the terminal device receives third indication information. The third indication information is used to update the SSB resource corresponding to the QCL resource in the TCI state. The TCI state indicated by the second indication information may be the same as the TCI state used by the terminal device before receiving the second indication information, but the SSB resource corresponding to the QCL resource in the TCI state indicated by the second indication information is different from the SSB resource corresponding to the QCL resource in the TCI state used by the terminal device before receiving the second indication information.
[0254] In this implementation, the measurement result corresponding to the first event in step 901a is meaningless to the network device. That is, the measurement result corresponding to the first event includes the measurement result of the service beam used by the terminal device before the service beam changed and / or the measurement result of the new beam. However, in this implementation, the service beam of the terminal device changes. Therefore, it is unnecessary for the terminal device to report the measurement result. In this application, in this case, the terminal device cancels the transmission operation of the uplink control channel and / or the corresponding uplink data channel. This avoids unnecessary reporting of measurement results and reduces uplink resource overhead.
[0255] Third, within the first time window, the new beam measurement resources of the terminal equipment change.
[0256] Optionally, within the first time window, a change in the new beam measurement resources of the terminal device can be described as any of the following:
[0257] 1. Within the first time window, the new beam of the terminal device changes.
[0258] 2. Within the first time window, the terminal device's new beam measurement resources are updated. For example, the terminal device receives an RRC reconfiguration message from the network device. This RRC reconfiguration message is used to reconfigure the terminal device's new beam measurement resources. The new beam measurement resources configured in this RRC reconfiguration message are different from the new beam measurement resources configured for the terminal device before the RRC reconfiguration message.
[0259] In this implementation, the measurement result corresponding to the first event in step 901a is meaningless to the network device. That is, the measurement result corresponding to the first event includes the measurement result of the serving beam and / or the measurement result of the new beam configured by the network device for the terminal device before the new beam changes. However, in this implementation, the new beam of the terminal device changes. Therefore, it is unnecessary for the terminal device to report this measurement result. In this application, in this case, the terminal device cancels the transmission operation of the uplink control channel and / or the corresponding uplink data channel. This avoids unnecessary reporting of measurement results and reduces uplink resource overhead.
[0260] IV. Within the first time window, the threshold value corresponding to the first event is updated. For example, the network device can reconfigure the threshold value corresponding to the first event via an RRC reconfiguration message. For example, the first event is: the signal quality of the serving beam of the terminal device is lower than the first threshold value. The threshold value corresponding to the first event is this first threshold value. This first threshold value is updated. As another example, the first event is: there exists at least one new beam with a signal quality higher than the serving beam's signal quality, and the signal quality of the at least one new beam is higher than the serving beam's signal quality by a second threshold value. The threshold value corresponding to the first event is this second threshold value. This second threshold value is updated. As yet another example, the first event is: there exists at least one new beam with a signal quality higher than the first active beam's signal quality, and the signal quality of the at least one new beam is higher than the first active beam's signal quality by a third threshold value. The threshold value corresponding to the first event is the third threshold value. This third threshold value is updated.
[0261] In this implementation, before the threshold value corresponding to the first event is updated, the terminal device determines whether to report the event-triggered measurement result based on the threshold value before the update of the first event. However, when the threshold value corresponding to the first event changes, the measurement result corresponding to the first event in step 901a above is meaningless to the network device. In this application, in this case, the terminal device cancels the transmission operation of the uplink control channel and / or the corresponding uplink data channel. This avoids unnecessary reporting of measurement results and reduces uplink resource overhead.
[0262] In one possible implementation, when the uplink control channel is used to request the scheduling of a first uplink data channel for the terminal device, the first reporting configuration is associated with mode A. That is, the terminal device reports measurement results using mode A. When the first event occurs, the terminal device may send the uplink control channel and / or the first reporting data channel. However, if the first condition is also met, the terminal device cancels the transmission of the uplink control channel and / or the transmission of the first uplink data channel.
[0263] In another possible implementation, when the uplink control channel is used to notify the network device that the measurement result corresponding to the first event is carried on the second uplink data channel, the first reporting configuration is associated with mode B. That is, the terminal device reports the measurement result using mode B. When the number of occurrences of the first event is greater than or equal to a first threshold, the terminal device can send the uplink control channel and / or the second uplink data channel. However, if the first condition is still met, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel.
[0264] Optionally, step 902 above can be described as follows: when the third condition is met, the terminal device sends an uplink control channel and / or a first uplink data channel, or the terminal device sends an uplink control channel and / or a second uplink data channel.
[0265] The third condition includes at least one of the following:
[0266] 1. During the transmission time of the uplink control channel, if the first timer has not started counting, the terminal device is prohibited from reporting event-triggered measurement results within the duration of the first timer.
[0267] Second, within the first time window, the service beam measurement resources of the terminal equipment did not change.
[0268] Optionally, the statement that the service beam measurement resources of the terminal device did not change within the first time window can be replaced by any of the following:
[0269] 1. Within the first time window, the service beam of the terminal device did not change.
[0270] 2. Within the first time window, the TCI status currently used or indicated by the terminal device does not change.
[0271] 3. Within the first time window, the QCL resources currently used or indicated by the terminal device in the TCI state do not change.
[0272] 4. Within the first time window, the SSB resources corresponding to the QCL resources currently used or indicated in the TCI state of the terminal device do not change.
[0273] Third, within the first time window, the new beam measurement resources of the terminal equipment did not change.
[0274] Optionally, the statement that the terminal device's new beam measurement resources have not changed within the first time window can be replaced by any of the following:
[0275] 1. Within the first time window, the new beam of the terminal device did not change.
[0276] 2. Within the first time window, the new beam measurement resources of the terminal equipment were not updated.
[0277] Fourth, within the first time window, the threshold value corresponding to the first event is not updated.
[0278] Please refer to the aforementioned introduction for the threshold value corresponding to the first event. It will not be repeated here.
[0279] In this embodiment, optionally, the uplink control channel in step 901 above is a periodic uplink control channel. The periodic control channel includes multiple uplink control channel transmission opportunities. Specifically, the uplink control channel in step 901 above can be understood as one uplink control channel transmission opportunity within the periodic control channel.
[0280] In this implementation, optionally, step 901 can be described as follows: The terminal device determines the timing for transmitting the first uplink control channel. The first uplink control channel transmitted at the first uplink control channel transmission timing is used to request the scheduling of a first uplink data channel for the terminal device. Alternatively, the first uplink control channel transmitted at the first uplink control channel transmission timing is used to notify the network device that the first measurement result corresponding to the first event is carried on the second uplink data channel. That is, the first uplink control channel transmission timing is a transmission timing for the uplink control channel. The first uplink control channel is carried on this first uplink control channel transmission timing.
[0281] In this implementation, optionally, the second moment mentioned above includes at least one of the following:
[0282] 1. The second moment is the transmission time corresponding to the first uplink control channel transmission opportunity.
[0283] 2. The second time is the time corresponding to the transmission time of the first uplink control channel transmission opportunity minus the first time offset.
[0284] 3. The second moment is the time before the transmission time corresponding to the first uplink control channel transmission opportunity, which is the time when the first event last occurred.
[0285] 4. The second moment is the current time. Please refer to the previous introduction for information about the current time, which will not be repeated here.
[0286] 5. The second moment is the time when the first event occurs.
[0287] 6. The second moment is the time when the CSI reference resource corresponding to the first reported configuration is configured.
[0288] In this implementation, optionally, step 902 can be described as follows: when the fourth condition is met, the terminal device cancels the transmission operation of the first uplink control channel and / or the transmission operation of the first uplink data channel corresponding to the first uplink control channel transmission timing, or the terminal device cancels the transmission operation of the first uplink control channel and / or the transmission operation of the second uplink data channel corresponding to the first uplink control channel transmission timing.
[0289] The fourth condition includes at least one of the following:
[0290] 1. When the first uplink control channel is transmitted, the first timer is counting down. During the duration of the first timer, the terminal device is prohibited from reporting measurement results based on event triggering.
[0291] Second, within the first time window, the service beam measurement resources of the terminal equipment change.
[0292] Third, within the first time window, the new beam measurement resources of the terminal equipment change.
[0293] For the replacement descriptions of the second and third items, please refer to the relevant introductions above, which will not be repeated here.
[0294] Fourth, within the first time window, the terminal device sends a second uplink control channel to the network device. This second uplink control channel requests the scheduling of a third uplink data channel for the terminal device. The third uplink data channel carries the second measurement result corresponding to the first event. Alternatively, the second uplink control channel notifies the network device that the second measurement result corresponding to the first event is carried on a fourth uplink data channel. For example, the fourth uplink data channel is a pre-configured uplink channel, such as a pre-configured PUSCH.
[0295] 5. Within the first time window, the threshold value corresponding to the first event is updated.
[0296] In this implementation, step 902 can optionally be described as follows: when the fifth condition is met, the terminal device transmits the first uplink control channel and / or the first uplink data channel at the first uplink control channel transmission time, or the terminal device transmits the first uplink control channel and / or the second uplink data channel at the first uplink control channel transmission time.
[0297] The third condition includes at least one of the following:
[0298] 1. When the first uplink control channel is transmitted, if the first timer is not in progress, the terminal device is prohibited from reporting event-triggered measurement results during the duration of the first timer.
[0299] Second, within the first time window, the service beam measurement resources of the terminal equipment did not change.
[0300] Third, within the first time window, the new beam measurement resources of the terminal equipment did not change.
[0301] For the replacement descriptions of the second and third items, please refer to the relevant introductions above, which will not be repeated here.
[0302] Fourth, within the first time window, the threshold value corresponding to the first event is not updated.
[0303] In the embodiment shown in Figure 9 above, the terminal device determines an uplink control channel. This uplink control channel is used to request the scheduling of a first uplink data channel for the terminal device. The first uplink data channel is used to carry the measurement result corresponding to the first event, or the first uplink control channel is used to notify the network device that the measurement result corresponding to the first event is carried on a second uplink data channel. Therefore, when the first event occurs or the number of times the first event occurs within a first time window is greater than or equal to a first threshold, the terminal device can send an uplink control channel to facilitate the terminal device reporting the measurement result corresponding to the first event. However, when the first condition is met, the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the first uplink data channel, or the terminal device cancels the transmission operation of the uplink control channel and / or the transmission operation of the second uplink data channel; wherein, the first condition includes at least one of the following: during the transmission time of the uplink control channel, the first timer is counting down, and the terminal device is prohibited from reporting event-triggered measurement results during the counting duration of the first timer; within the first time window, the serving beam measurement resource of the terminal device changes; within the first time window, the new beam measurement resource of the terminal device changes; or within the first time window, the threshold value corresponding to the first event is updated. It can be seen that when the first condition is met, the terminal device can cancel the transmission operation of the uplink control channel and / or the transmission operation of the uplink data channel, thereby avoiding unnecessary reporting of measurement results and reducing uplink resource overhead.
[0304] The embodiment shown in Figure 9 above provides a scheme for a terminal device to cancel the transmission operation of the uplink control channel and / or the transmission operation of the uplink data channel. This scheme can avoid unnecessary measurement result reporting and reduce uplink resource overhead. In practice, the terminal device can also avoid unnecessary measurement result reporting by updating the first time window. The following description is based on the embodiment shown in Figure 11. Figure 11 is a schematic diagram of an embodiment of the update method of this application. Referring to Figure 11, the method includes:
[0305] 1101. The terminal device determines whether to report the measurement results based on the event trigger based on the number of times the first event occurs within the first time window.
[0306] Specifically, the network device configures a first reporting configuration for the terminal device. This first reporting configuration is associated with reporting mode two. Please refer to the previous description for reporting mode two. The first reporting configuration is associated with one or more measurement results and a first event. The terminal device can measure the reference signal corresponding to the one or more measurement resources to obtain the measurement result. The terminal device can determine whether to report the measurement result based on the number of times the first event occurs within a first time window. Please refer to the description in the embodiment shown in Figure 9 above for the first time window. For example, if the number of times the first event occurs within the first time window is greater than or equal to a first threshold, then the terminal device determines to report the measurement result. If the number of times the first event occurs within the first time window is less than the first threshold, then the terminal device determines not to report the measurement result.
[0307] Optionally, the embodiment shown in FIG11 further includes step 1100a. Step 1100a may be performed before step 1101.
[0308] 1100a. The network device sends the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.
[0309] Step 1100a is similar to step 900a in the embodiment shown in Figure 9 above. For details, please refer to the relevant description of step 900a in the embodiment shown in Figure 9 above, which will not be repeated here.
[0310] Optionally, the embodiment shown in FIG11 further includes step 1100b. Step 1100b may be performed before step 1101.
[0311] 1100b. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.
[0312] Step 1100b is similar to step 900b in the embodiment shown in Figure 9 above. For details, please refer to the relevant description of step 900b in the embodiment shown in Figure 9 above, which will not be repeated here.
[0313] 1102. When the second condition is met, update the first time window to obtain the second time window.
[0314] The second condition includes at least one of the following:
[0315] 1. Within the first time window, the service beam measurement resources of the terminal equipment change.
[0316] Second, within the first time window, the new beam measurement resources of the terminal equipment change.
[0317] For some of the alternative descriptions in the first and second items, please refer to the relevant introductions above, which will not be repeated here.
[0318] Third, within the first time window, the threshold value corresponding to the first event is updated. Please refer to the aforementioned introduction for the threshold value corresponding to the first event; it will not be repeated here.
[0319] Fourth, within the first time window, the terminal device sends an uplink control channel to report the event-triggered measurement results.
[0320] For information on the first time window, please refer to the relevant description in the embodiment shown in Figure 9 above.
[0321] The second time window is the duration between the third time point and the second time point, where the third time point is a single moment within the first time window. For example, as shown in Figure 10, the first time window is the time interval between time t1 and time t2. The second time window is the time interval between time t3 and time t2.
[0322] Time t3 is a time point within the first time window. Optionally, the third time point may include at least one of the following:
[0323] 1. The third moment is the moment when the service beam measurement resources of the terminal device change. In other words, the third moment is the moment when the service beam of the terminal device changes. Alternatively, the third moment is the moment when the TCI state currently used or indicated by the terminal device changes. Alternatively, the third moment is the moment when the QCL resources in the TCI state currently used or indicated by the terminal device change. Alternatively, the third moment is the moment when the SSB resources corresponding to the QCL resources in the TCI state currently used or indicated by the terminal device change.
[0324] As shown in Figure 10, the service beam measurement resources of the terminal device change at time t3. The measurement results obtained by the terminal device from measuring the measurement resources associated with the first reporting configuration during the time interval between time t1 and time t3 are meaningless to the network device. That is, the number of occurrences of the first event during the time interval between time t1 and time t3 cannot be used as the basis for determining whether to report the event-triggered measurement results. Therefore, the terminal device can update the first time window to obtain a second time window. Then, the terminal device determines whether to report the event-triggered measurement results based on the number of occurrences of the first event within the second time window. As shown in Figure 10, the terminal device determines the number of occurrences of the first event during the time interval between time t3 and time t2. If the number of occurrences of the first event is greater than or equal to a first threshold, the terminal device can report the event-triggered measurement results.
[0325] 2. The third moment is when the terminal device sends the uplink control channel.
[0326] As shown in Figure 10, at time t3, the terminal device has already sent an uplink control channel. Please refer to the relevant description in the embodiment shown in Figure 9 above for information on the uplink control channel. That is, the number of occurrences of the first event within the time interval between time t1 and time t3 cannot be used again as the basis for determining whether to report the event-triggered measurement result. The terminal device can shift the starting position of the first time window to time t3 to obtain a second time window. Then, the terminal device determines the number of occurrences of the first event within the time interval between time t3 and time t2. If the number of occurrences of the first event is greater than or equal to a first threshold, the terminal device can report the event-triggered measurement result.
[0327] 3. The third moment is the moment when the threshold value corresponding to the first event is updated.
[0328] As shown in Figure 10, before time t3, the terminal device determines whether to report event-triggered measurement results based on the threshold value before the update of the first event. However, when the threshold value corresponding to the first event changes, the measurement results obtained by the terminal device from measuring the measurement resources associated with the first reporting configuration during the time interval between time t1 and time t3 are meaningless to the network device. In other words, the number of times the first event occurs during the time interval between time t1 and time t3 cannot be used as the basis for determining whether to report event-triggered measurement results. The terminal device can move the starting position of the first time window to time t3 to obtain a second time window. Then, the terminal device determines the number of times the first event occurs during the time interval between time t3 and time t2. If the number of times the first event occurs is greater than or equal to the first threshold, the terminal device can report event-triggered measurement results.
[0329] 4. The third moment is the moment when the new beam measurement resources of the terminal equipment change. In other words, the third moment is the moment when the new beam of the terminal equipment changes.
[0330] Therefore, as shown in Figure 10, the new beam measurement resources of the terminal device change at time t3. The measurement results obtained by the terminal device from measuring the measurement resources associated with the first reporting configuration during the time interval between time t1 and time t3 are meaningless to the network device. That is, the number of occurrences of the first event during the time interval between time t1 and time t3 cannot be used as the basis for determining whether to report the event-triggered measurement results. Therefore, the terminal device can update the first time window to obtain a second time window. Then, the terminal device determines whether to report the event-triggered measurement results based on the number of occurrences of the first event within the second time window. As shown in Figure 10, the terminal device determines the number of occurrences of the first event during the time interval between time t3 and time t2. If the number of occurrences of the first event is greater than or equal to a first threshold, the terminal device can report the event-triggered measurement results.
[0331] In step 1101 above, during the process of the terminal device determining whether to report the event-triggered measurement result, if the second condition is met, the terminal device updates the first time window to obtain the second time window. It should be noted that if the terminal device reports the event-triggered measurement result within the first time window, the terminal device may not need to update the first time window.
[0332] 1103. The terminal device determines whether to report the event-triggered measurement results based on the number of times the first event occurs within the second time window.
[0333] In the embodiment shown in Figure 11 above, if the second condition is met, the terminal device updates the first time window to obtain a second time window. As shown in Figure 10, the second time window falls within the first time window. The terminal device determines whether to report the event-triggered measurement results based on the number of occurrences of the first event within the second time window. This helps avoid unnecessary reporting of measurement results and reduces uplink resource overhead.

[0357] It should be noted that the communication device 1300 may include a transmitting module but not a receiving module.

For details, please refer to the relevant descriptions in the embodiments shown in Figures 9 and 11; these will not be elaborated upon here.
[0358] For example, the communication device 1300 is used to execute the following scheme:
[0359] Processing module 1302 is used to determine an uplink control channel, which is used to request the scheduling of a first uplink data channel for communication device 1300, and the first uplink data channel is used to carry the measurement result corresponding to the first event; or, the uplink control channel is used to notify the network device that the measurement result corresponding to the first event is carried on a second uplink data channel.

[0368] This application embodiment also provides a communication device 1400. Referring to FIG14, the communication device 1400 includes a processor 1410, which is coupled to a memory 1420. The memory 1420 is used to store computer programs or instructions and / or data. The processor 1410 is used to execute the computer programs or instructions and / or data stored in the memory 1420, causing the methods in the above method embodiments to be executed. The communication device 1400 is used to implement the operations performed by the terminal device or network device in the above method embodiments.
[0369] Optionally, the communication device 1400 may include one or more processors 1410.
[0370] Optionally, as shown in FIG14, the communication device 1400 may also include a memory 1420.
[0371] Optionally, the communication device 1400 may include one or more memory 1420.
[0372] Optionally, the memory 1420 can be integrated with the processor 1410 or set separately.
[0373] Optionally, as shown in FIG14, the communication device 1400 may further include a transceiver 1430 for receiving and / or transmitting signals. For example, the processor 1410 is used to control the transceiver 1430 to receive and / or transmit signals.
[0374] This application also provides a communication device 1500, which can be a terminal device, a processor in the terminal device, or a chip. The communication device 1500 can be used to perform the operations performed by the terminal device in the above method embodiments.
[0375] When the communication device 1500 is a terminal device, Figure 15 shows a simplified structural diagram of the terminal device. As shown in Figure 15, the terminal device includes a processor, a memory, and a transceiver. The memory can store computer program code, and the transceiver includes a transmitter 1531, a receiver 1532, radio frequency circuitry (not shown in the figure), an antenna 1533, and input / output devices (not shown in the figure).
[0376] The processor is mainly used to process communication protocols and communication data; control terminal devices; execute software programs; and process data from software programs.
[0377] Memory is mainly used to store software programs and data.
[0378] Radio frequency (RF) circuits are mainly used for the conversion between baseband signals and RF signals, as well as for the processing of RF signals.
[0379] Antennas are primarily used for transmitting and receiving radio frequency signals in the form of electromagnetic waves.
[0380] Input / output devices can include touchscreens, displays, or keyboards. They are primarily used to receive user input and output data to the user. It should be noted that some types of terminal devices may not have input / output devices.
[0381] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits it outwards via an antenna as electromagnetic waves. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal back into a baseband signal and outputs it to the processor. The processor converts the baseband signal back into data and processes the data. For ease of explanation, Figure 15 only shows one memory, processor, and transceiver.
