Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a communication method and device, a terminal device and a network device. BACKGROUND

[0002] With the continuous development of communication technology, beamforming technology is widely used to realize efficient transmission of high-frequency signals. Beamforming technology adjusts the direction of transmitted and received signals so that the signals can be more concentratedly directed to users, thereby improving the transmission efficiency and coverage of the signals. The effective application of beamforming technology cannot be achieved without accurate beam adjustment.

[0003] Due to the influence of various factors such as multipath effect and building obstruction on wireless signals during transmission, the actual transmission path of the signals deviates from the expected path. In order to ensure that the beam can be accurately directed to the user, beam report transmission is needed to quickly feed back the signal quality of the beam. For example, the network can adjust the direction of the beam according to the beam report to ensure that the signal can cover the user and reduce the interference between users; the terminal device can select the best receiving beam according to the beam report to improve the reception quality and stability of the signal.

The term "network element" can also be referred to as an entity, device, apparatus, or module, without specific limitation. Furthermore, for ease of understanding and explanation, the description of "network element" will be omitted in some descriptions. For example, a network exposure function (NEF) network element may be abbreviated as NEF. In this case, "NEF" should be understood as either a NEF network element or a NEF entity.

[0130] The AF (Action Center) can interact with core network elements to provide services. For example, the AF interacts with the PCF (Programmable Component Function) for service policy control, with the NEF (Network Component Function) to obtain network capability information or provide application information to the network, and with the PCF to provide data network access point information to generate corresponding data service routing information.

[0131] NEF can be responsible for providing network-related status information to application services.

[0132] The Authentication Server Function (AUSF) can implement access authentication for both 3GPP and non-3GPP systems.

[0133] Unified Data Management (UDM) provides unified data management functions, including 3GPP AKA authentication, user identification, access authorization, registration, mobility, subscription, and SMS management.

[0134] The network slice selection function (NSSF) can determine the network slice instances that a terminal device is allowed to access based on the terminal device's slice selection assistance information, subscription information, and other factors.

[0135] The network repository function (NRF) can be a new feature that provides registration and discovery capabilities, enabling network functions (NFs) to discover each other and communicate via an API interface.

[0136] Unified data management (UDM) can be responsible for the management of user identifiers, subscription data, authentication data, and user service element registration management.

[0137] The unified data repository (UDR) can be used by UDM to store or retrieve subscription data, and by PCF to store or retrieve policy data.

[0138] The network data analytics function (NWDAF) can provide network analysis services based on request data from network services.

[0139] The network slice specific authentication and authorization function (NSSAAF) can be used to provide authentication and authorization for specific network slices.

[0140] It should be noted that the terminal device connects to the access network device wirelessly, and the access network device connects to the core network device wirelessly or via a wired connection. The access network device and the core network device can be independent physical devices, or the functions of the core network device and the logical functions of the access network device can be integrated into the same physical device, or a single physical device can integrate some of the functions of the core network device and some of the functions of the access network device.

[0141] For example, Figure 2 This is a schematic diagram of the architecture of another communication system according to an embodiment of this application. Wherein, Figure 2The names of the network elements included are merely names and do not limit the function of the network element itself. In 5G networks and other future networks, the aforementioned network elements may also have other names, without specific restrictions. For example, in 6G networks, some or all of the aforementioned network elements may use the terminology from 5G, or they may have other names, etc. This is explained uniformly here and will not be elaborated further below.

[0142] in addition, Figure 2 The various network elements in the network do not necessarily have to exist at the same time; the required network elements can be determined based on the needs. Figure 2 The connection relationships between the various network elements are not uniquely defined and can be adjusted according to requirements. It is understood that the aforementioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform).

[0143] certainly, Figure 2 This is merely an example of a network architecture for a communication system and does not constitute a limitation on the network architecture of the communication systems in the embodiments of this application.

[0144] [Beam Report Transmission Process]

[0145] The communication system has been described above. The beam report transmission process of this embodiment will be explained in detail below.

[0146] To ensure the beam is accurately pointed at the user, beam reports need to be transmitted to provide timely feedback on the beam's signal quality, thereby guaranteeing communication quality between network devices and terminal devices. For example, network devices can adjust the beam's direction based on the beam report to ensure signal coverage of the user while reducing interference between users; terminal devices can select the optimal receiving beam based on the beam report to improve signal reception quality and stability.

[0147] In some possible examples, beam reports include at least one of the following: beam pointing angle, signal strength, beam index, reference signal index, event type information, cell index, or transmission quality.

[0148] In some possible examples, the beam report in this embodiment can be a UE-initiated beam report or an event-driven beam report. It should be noted that an event-driven beam report can also be a beam report initiated by the terminal device.

[0149] In some possible examples, for a beam report initiated by the terminal device or an event-triggered beam report, the terminal device may perform the following steps: the terminal device performs event detection; based on the event detection, the terminal device sends a beam report. Of course, the terminal device may perform different steps than those described above, or may perform other steps in addition to the steps described above, without specific limitations.

[0150] In some possible examples, the events mentioned above include at least one of the following:

[0151] Event 1: The signal quality of the current beam (such as the layer 1-reference signal receiving power (L1-RSRP)) is below (less than) the threshold.

[0152] Thus, if the signal quality of the current beam is lower than a predefined or network-configured threshold, the terminal device may send a beam report. Therefore, event 1 allows the network to switch to a better beam to maintain a stable connection.

[0153] Event 2: The signal quality of at least one new beam exceeds a threshold compared to the signal quality of the current beam. In other words, the difference between the signal quality of the at least one new beam and the signal quality of the current beam is greater than or equal to the threshold.

[0154] In this way, if the signal quality of the new beam is better than that of the current beam, the terminal device may send a beam report. This provides the network with more options regarding beam switching or aggregation.

[0155] Event 3: The signal quality of the new beam is higher than (greater than / exceeds) the threshold.

[0156] Thus, if the signal quality of a new beam exceeds a threshold, the terminal device may send a beam report. Therefore, Event 3 can help the network identify potentially better beams for future handover or beam switching.

[0157] Event 4: The signal quality of the current beam is below the first threshold, and the signal quality of at least one new beam is above the second threshold.

[0158] Thus, event 4 combines events 1 and 3, requiring both events to be satisfied simultaneously. Therefore, event 4 ensures that beam reporting is triggered only when the current beam performance is poor and a better beam is available.

[0159] Event 5: The absolute value of the difference in signal quality between the current beam and at least one new beam is below a threshold.

[0160] In this way, if the signal quality difference between the current beam and the new beam is small, the terminal device may send a beam report indicating that the new beam may be a suitable candidate for switching or beam swapping.

[0161] Event 6: The current beam is not among the optimal K (K is a positive integer and K>1) beams, which are the K beams configured for measurement and reporting.

[0162] Thus, if the current beam is not among the K best beams configured for measurement and reporting, the terminal device may send a beam report.

[0163] Event 7a: The signal quality of at least one new beam is greater than the signal quality of the reference signal with the worst signal quality from the active transmission configuration indicator (TCI) state by a threshold. In other words, the difference between the signal quality of the at least one new beam and the signal quality of the reference signal is greater than or equal to the threshold.

[0164] Thus, if the signal quality of the new beam is better than the worst signal quality from the active TCI state, the terminal device may send a beam report.

[0165] Event 7b: The signal quality of at least one new beam exceeds a threshold compared to the signal quality of the reference signal with the best signal quality in the activated TCI state. In other words, the difference between the signal quality of the at least one new beam and the signal quality of the reference signal is greater than or equal to the threshold.

[0166] Thus, if the signal quality of the new beam is better than the best signal quality from the active TCI state, the terminal device may send a beam report.

[0167] Event 8: The signal quality of M+1 new beams exceeds a threshold compared to the signal quality of the current beam. In other words, the difference between the signal quality of the M new beams and the signal quality of the current beam is greater than or equal to the threshold.

[0168] Thus, if the signal quality of the M new beams is better than that of the current beam, the terminal device may send a beam report. This provides the network with more options regarding beam switching or aggregation.

[0169] Event 9: The signal quality of at least one new beam exceeds a threshold compared to the signal quality of the configured reference signal. In other words, the difference between the signal quality of the at least one new beam and the signal quality of the configured reference signal is greater than or equal to the threshold.

[0170] Thus, if the signal quality of the new beam is better than that of the configured reference signal, the terminal device may send a beam report.

[0171] Of course, in addition to the events described above, there may be other events involved in this embodiment, and no specific limitations are imposed on them.

[0172] The following provides a detailed explanation of how to transmit beam reports.

[0173] Taking the interaction between terminal devices and network devices as an example, such as Figure 3 As shown, Figure 3 This is a schematic diagram of a communication method according to an embodiment of this application, which specifically includes the following steps:

[0174] S310. The terminal device sends a beam report according to the transmission mode of the beam report, which is either the first mode or the second mode, and the beam report is either a beam report initiated by the terminal device or a beam report triggered by an event.

[0175] Correspondingly, the network device receives the beam report.

[0176] It should be noted that for beam reports initiated by terminal devices or triggered by events, the transmission mode of the beam report can be either the first mode or the second mode. The first mode and the second mode are explained in detail below.

[0177] [Mode 1]

[0178] The first mode may include the following three steps:

[0179] Step 1: The terminal device requests uplink resources from the network device for transmitting / carrying beam reports.

[0180] In step 1 of the first mode, the terminal device may send first uplink information to the network device. This first uplink information can be used to request uplink resources from the network for transmitting / bearing beam reports. The first uplink information is carried by uplink resources. Optionally, these uplink resources are pre-configured.

[0181] In this way, the network device can indicate the uplink resources for transmitting / carrying beam reports to the terminal device based on the first uplink information, so as to ensure the transmission of beam reports.

[0182] In some possible examples, prior to step 1 of the first mode, the network device may configure uplink resources for carrying the first uplink information to the terminal device via downlink control information (DCI), MAC signaling, RRC signaling, and / or system information. Therefore, these uplink resources can be considered pre-configured. For example, the network device sends a DCI to the terminal device indicating the uplink resources used to carry the first uplink information.

[0183] In addition, since the uplink resources used for transmitting / bearing beam reports are requested by the terminal device from the network device, the network device indicates the uplink resources used for transmitting / bearing beam reports to the terminal device according to the request.

[0184] In some possible examples, the uplink resource used to transmit the first uplink information is the physical uplink control channel (PUCCH) resource, and the first uplink information is either a scheduling request (SR) or uplink control information (UCI). The SR or UCI is used to request uplink resources from the network for transmitting beam reports.

[0185] For example, taking the first uplink information as SR, the terminal device transmits SR on PUCCH resources. SR is used to request the first uplink resources from the network for transmitting beam reports.

[0186] In some possible examples, the first uplink information includes one or more bits.

[0187] In some possible examples, the uplink resource used to transmit beam reports is either a PUCCH resource or a physical uplink shared channel (PUSCH) resource. Thus, beam reports can be carried by either a PUCCH or a PUSCH.

[0188] Step 2: The network device indicates the uplink resources to the terminal device for carrying beam reports.

[0189] In step 2 of the first mode, the network device may send first downlink information to the terminal device. The first downlink information is used to indicate to the terminal device the uplink resources used to carry beam reporting. The first downlink information is carried by the downlink resources.

[0190] In some possible examples, the downlink resources used to transmit / carry the first downlink information are physical downlink control channel (PDCCH) resources, and the first downlink information is carried by the DCI. That is, the DCI is used to indicate to the terminal equipment the uplink resources used to carry beam reports.

[0191] It should be noted that there are various DCI formats, each with its specific purpose and field definitions. A DCI may contain fields indicating uplink resource allocation. When a terminal device decodes a DCI, it checks the fields to determine if uplink resources have been allocated to it. For beam reporting, a DCI may contain fields indicating the first uplink resource. For example, a DCI may instruct the terminal device to use a specific uplink channel and / or corresponding time-frequency resources to transmit the beam report. Furthermore, a DCI may also contain other parameters related to beam report transmission, such as modulation scheme and / or coding scheme.

[0192] Therefore, when the terminal device detects the DCI and decodes its fields, it can determine the first uplink resource and transmit the beam report according to the corresponding parameters and configuration.

[0193] Step 3: The terminal device sends a beam report to the network device.

[0194] In step 3 of the first mode, the terminal device transmits a beam report on the uplink resources indicated by the network. This ensures the reliability of beam report transmission by using the uplink resources indicated by the network.

[0195] For ease of distinction and description, in the first mode, this embodiment refers to the "uplink resource used to transmit / carry the first uplink information" as the "third uplink resource," the "uplink resource used to transmit / carry beam reporting" as the "first uplink resource," and the "downlink resource used to transmit / carry the first downlink information" as the "first downlink resource." Optionally, the third uplink resource is pre-configured, and the first uplink resource is indicated by the network.

[0196] The following example illustrates the temporal distribution of the third uplink resource, the first downlink resource, and the first uplink resource in the first mode. Figure 4 As shown. In Figure 4In this configuration, the third uplink resource, the first downlink resource, and the first uplink resource are distributed sequentially in time. The time domain position of the third uplink resource precedes the time domain positions of the first downlink resource and the first uplink resource, and the time domain position of the first downlink resource precedes the time domain position of the first uplink resource. Specifically, in step 1 of the first mode, the terminal device transmits first uplink information on the third uplink resource, which is used to request uplink resources from the network for transmitting / carrying beam reports; in step 2 of the first mode, the terminal device receives first downlink information on the first downlink resource, which is used to indicate the first uplink resource to the terminal device; in step 3 of the first mode, the terminal device transmits beam reports on the first uplink resource.

[0197] [Second Mode]

[0198] The second mode may include the following two steps:

[0199] Step 1: The terminal device notifies the network device that it wants or will transmit a beam report on a pre-configured uplink resource, or the terminal device notifies the network device that it will transmit a beam report on a pre-configured uplink resource.

[0200] In step 1 of the second mode, the terminal device may send second uplink information to the network device. This second uplink information is used to notify the network that the terminal device wants to or will transmit a beam report on a pre-configured uplink resource; or, the second uplink information is used to notify the network that a beam report will be transmitted / carried on a second uplink resource. Furthermore, the second uplink information is carried by the uplink resource. Optionally, this uplink resource is pre-configured. In this way, the network device can know from the second uplink information that the terminal device wants to or will transmit a beam report on a pre-configured uplink resource, thereby ensuring the transmission of the beam report.

[0201] In some possible examples, the uplink resources used to carry / transmit the second uplink information in step 1 of the second mode may be the same as or different from the uplink resources used to carry / transmit the first uplink information in step 1 of the first mode.

[0202] In some possible examples, prior to step 1 of the second mode, the network device may configure one or more uplink resources for transmitting beam reports to the terminal device via at least one of DCI, MAC signaling, RRC signaling, or system information. Therefore, these one or more uplink resources can be considered pre-configured. Thus, the terminal device may notify the network device via second uplink information that it wants to or will transmit beam reports on one of these one or more uplink resources, or the terminal device may notify the network device via second uplink information that it will transmit beam reports on one of these one or more uplink resources.

[0203] In some possible examples, the uplink resource used to transmit / carry the second uplink information is a PUCCH resource, and the second uplink information is SR or UCI. The SR or UCI is used to notify the network that the terminal device wants to or will transmit beam reports on the second uplink resource, or the SR or UCI is used to notify the network that the terminal device will transmit beam reports on the second uplink resource.

[0204] For example, taking the second uplink information as SR, the terminal device transmits SR on the PUCCH resource. SR is used to notify the network that the terminal device wants to or will transmit beam reports on the second uplink resource, or SR is used to notify the network that the terminal device will transmit beam reports on the second uplink resource.

[0205] In some possible examples, the second uplink information includes one or more bits.

[0206] In some possible examples, the pre-configured uplink resource is either a PUCCH resource or a PUSCH resource. Thus, beam reporting can be carried by either PUCCH or PUSCH.

[0207] In some possible examples, this embodiment can explicitly inform the terminal device of its consent to transmit beam reports on the second uplink resource. For example, after step 1 in the second mode, the network device can send a first response message to the terminal device, which instructs the network device to consent to the terminal device transmitting beam reports on the second uplink resource. Thus, the terminal device can learn from the first response message that the network device consents to its transmission of beam reports on the second uplink resource.

[0208] In some possible examples, this embodiment can implicitly inform the terminal device of its consent to transmit beam reports on the second uplink resource. For example, for a period of time after step 1 in the second mode, the terminal device does not receive the second response information, which indicates that the network device does not consent to the terminal device transmitting beam reports on the second uplink resource. In this way, the terminal device can know that the network device consents to its transmission of beam reports on the second uplink resource.

[0209] Step 2: The terminal device sends a beam report to the network device.

[0210] In step 2 of the second mode, the terminal device transmits beam reports on the pre-configured uplink resources. This ensures the reliability of beam report transmission by utilizing the pre-configured uplink resources for beam report transmission.

[0211] For ease of distinction and description, in the second mode, this embodiment refers to the "uplink resource used to transmit / carry the second uplink information" as the "fourth uplink resource" and the "pre-configured uplink resource" as the "second uplink resource".

[0212] It should be noted that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources.

[0213] The following example illustrates the temporal distribution of the fourth and second uplink resources in the second mode. Figure 5 As shown. In Figure 5 In this configuration, the fourth uplink resource and the second uplink resource are distributed sequentially in time, with the time domain position of the fourth uplink resource preceding that of the second uplink resource. Specifically, in step 1 of the second mode, the terminal device transmits second uplink information on the fourth uplink resource. This second uplink information is used to notify the network that the terminal device wants to or will transmit a beam report on the second uplink resource, or alternatively, the second uplink information is used to notify the network that the terminal device will transmit a beam report on the second uplink resource. In step 2 of the second mode, the terminal device transmits a beam report on the second uplink resource.

[0214] In summary, for beam report transmission modes, the first mode indicates that the beam report is transmitted on the first uplink resource, and the second mode indicates that the beam report is transmitted on the second uplink resource. The first uplink resource is indicated by the network, and the second uplink resource is pre-configured.

[0215] It is evident that the main difference between the first and second modes lies in the resource allocation method: the first mode transmits beam reports based on dynamically scheduled uplink resources, while the second mode transmits beam reports based on pre-configured uplink resources.

[0216] Since the first mode and the second mode are two different transmission modes, this embodiment can determine a suitable transmission mode from the first mode and the second mode during the beam report transmission process to realize the beam report transmission, ensuring the reliability and / or timeliness of the beam report transmission. The following describes in detail how to determine the first mode or the second mode from "Mode 1", "Mode 2" or "Mode 3".

[0217] Method 1

[0218] In “Method 1”, since the network device can know the communication status of the entire network and / or the device capabilities of the terminal device, the network device can determine whether to use the first mode or the second mode under the current network and / or the current terminal device, so as to ensure the stability of beam transmission as much as possible and reduce the complexity of the terminal device.

[0219] Based on this, this embodiment can determine whether the beam report transmission mode is the first mode or the second mode through network indication. That is, the network device can indicate to the terminal device whether the beam report transmission mode is the first mode or the second mode through at least one of RRC signaling, DCI, MAC signaling or system information.

[0220] In this way, the terminal device determines the transmission mode indicated by the network indication based on at least one of RRC signaling, DCI, MAC signaling or system information, and transmits beam reports according to the transmission mode indicated by the network, thereby ensuring the reliability of beam report transmission and reducing the complexity of the terminal device.

[0221] Taking the interaction between terminal devices and network devices as an example, such as Figure 6 As shown, Figure 6 This is a schematic diagram of another communication method according to an embodiment of this application, which specifically includes the following steps:

[0222] S610. The network device sends a first indication message, which is used to indicate that the transmission mode of the beam report is a first mode and / or a second mode.

[0223] Correspondingly, the terminal device receives the first instruction information.

[0224] In some possible examples, the first indication information is carried by at least one of RRC signaling, DCI, MAC signaling, or system information. Thus, the transmission mode of network indication beam reporting is implemented via at least one of RRC signaling, DCI, MAC signaling, or system information.

[0225] S620 is the same as S310, so it will not be described again.

[0226] Correspondingly, network devices receive reports according to the transmission mode of beam reports.

[0227] As can be seen, this embodiment uses the first indication information to indicate to the terminal device that the beam report transmission mode is the first mode and / or the second mode, so that the terminal device can transmit the beam report according to the transmission mode indicated by the network, thereby ensuring the reliability and / or timeliness of the beam report transmission and reducing the complexity of the terminal device.

[0228] Method 2

[0229] In "Method 2," the network can configure certain conditions or standard protocols specify certain conditions based on factors such as network conditions, user needs, and equipment capabilities. These conditions can be used to determine whether the beam reporting transmission mode is Mode 1 or Mode 2. In this way, terminal devices or network devices can determine whether the beam reporting transmission mode is Mode 1 or Mode 2 based on these conditions. Examples of these conditions are given below.

[0230] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is less than a first time threshold, then the transmission mode of the beam report is the first mode.

[0231] It should be noted that before the terminal device transmits the beam report, the network device or terminal device can determine the time-domain location of the second uplink resource, the time-domain location of the third uplink resource, and the time-domain location of the fourth uplink resource. Specifically, the time-domain location of the third uplink resource precedes the time-domain location of the second uplink resource, and the time-domain location of the fourth uplink resource also precedes the time-domain location of the second uplink resource. Furthermore, this condition introduces a first time threshold.

[0232] It is worth noting that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources. When the third uplink resource and the fourth uplink resource are different uplink resources, the terminal device may transmit the first uplink information only on the third uplink resource or the second uplink information only on the fourth uplink resource. For the network device, it needs to detect the third uplink resource and the fourth uplink resource to confirm whether there is information being transmitted.

[0233] Based on this, when the terminal device transmits the first uplink information only on the third uplink resource, the network device or the terminal device can determine whether the time interval between the time domain location of the third uplink resource and the time domain location of the second uplink resource is less than a first time threshold. If the time interval is less than the first time threshold, the network device or the terminal device can determine that the transmission mode of the beam report is the first mode.

[0234] When a terminal device transmits second uplink information only on the fourth uplink resource, the network device or terminal device can determine whether the time interval between the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is less than a first time threshold. If the time interval is less than the first time threshold, the network device or terminal device can determine that the transmission mode of the beam report is the first mode.

[0235] Optionally, the time domain position of the second uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the second uplink resource; the time domain position of the third uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the third uplink resource; the time domain position of the fourth uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the fourth uplink resource.

[0236] For example, taking the starting time domain position of the second uplink resource, and the starting time domain position of the third uplink resource or the starting time domain position of the fourth uplink resource as an example, such as Figure 7 As shown, the time interval between the starting time domain position of the third uplink resource or the starting time domain position of the fourth uplink resource and the time domain position of the second uplink resource is ΔT1, and ΔT1 <T B T B This indicates the first time threshold.

[0237] Optionally, the first time threshold is defined by a standard protocol, indicated by network configuration, or depends on the device capabilities of the terminal device.

[0238] Optionally, the first time threshold is determined by the processing time of the first uplink channel, which is the uplink channel used to carry / transmit beam reports in the second mode. The first uplink channel can be either PUCCH or PUSCH.

[0239] For example, network configuration or standard protocols specify a mapping table between a first time threshold and the processing time of a first uplink channel. After determining the processing time of the first uplink channel, the first time threshold is determined based on this mapping table and the processing time of the first uplink channel. For another example, the first time threshold is the processing time of the first uplink channel.

[0240] Thus, if the time interval between the time domain location of the third uplink resource or the fourth uplink resource and the time domain location of the second uplink resource is less than the first time threshold, it indicates that the terminal device does not have enough time interval to process the first uplink channel after transmitting the first uplink information on the third uplink resource or the second uplink information on the fourth uplink resource. This prevents the terminal device from using the second mode to transmit beam reports. Therefore, the terminal device can use the first mode to transmit beam reports, thereby ensuring the reliability and / or timeliness of beam report transmission.

[0241] Optionally, the processing time of the first uplink channel may include the time required to process the uplink channel used to carry beam reporting in the second mode. For example, the processing time of the first uplink channel may include at least one of data preparation time, encoding time, or modulation time.

[0242] Data preparation time refers to the time required for data packaging after data is generated or collected by the terminal device. Data packaging refers to packaging data according to a specific protocol, such as dividing the data into appropriately sized data packets and adding necessary header information (such as source address, destination address, packet number, etc.).

[0243] Encoding time refers to the time required to encode data. Encoding is the process of converting raw data into a format suitable for transmission in a communication system. This can include source coding (such as data compression) and / or channel coding (such as adding redundancy information to detect and correct transmission errors). The encoding process may require a certain amount of computation time, depending on the complexity of the encoding algorithm and the amount of data to be processed.

[0244] Modulation time refers to the time required to encode data. Modulation is the process of converting a digital signal into an analog signal suitable for transmission over a physical medium (such as radio waves, cables, etc.). This typically involves mapping the digital signal to different frequencies, amplitudes, or phases. The modulation process can take a certain amount of time, especially when using complex modulation techniques.

[0245] Optionally, the processing time of the first uplink channel may be configured or indicated by the network, or it may be specified by a standard protocol, or it may depend on the device capabilities of the terminal equipment.

[0246] Optionally, since different terminal devices have different device capabilities, and different device capabilities may have different data processing capabilities, the processing time of the first uplink channel can be set according to the different device capabilities of the terminal devices.

[0247] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to the first time threshold, then the transmission mode of the beam report is the first mode.

[0248] It should be noted that before the terminal device transmits the beam report, the network device or terminal device can determine the time domain location of the second uplink resource, the time domain location of the third uplink resource, the time domain location of the fourth uplink resource, and the time domain location of the first downlink resource. Specifically, the time domain location of the third uplink resource precedes the time domain locations of the first downlink resource and the second uplink resource; the time domain location of the fourth uplink resource precedes the time domain location of the second uplink resource; and the time domain location of the first downlink resource precedes the time domain location of the second uplink resource.

[0249] It is worth noting that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources. When the third uplink resource and the fourth uplink resource are different uplink resources, the terminal device may transmit the first uplink information only on the third uplink resource or the second uplink information only on the fourth uplink resource. For the network device, it needs to detect the third uplink resource and the fourth uplink resource to confirm whether there is information being transmitted.

[0250] Based on this, when the terminal device transmits the first uplink information only on the third uplink resource, the network device or the terminal device can determine whether the time interval (i.e., the first time interval) between the time domain location of the third uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to the first time threshold. If the first time interval is greater than or equal to the first time threshold, and the second time interval is greater than or equal to the first time threshold, then the network device or the terminal device can determine that the beam reporting transmission mode is the first mode.

[0251] When the terminal device transmits second uplink information only on the fourth uplink resource, the network device or terminal device can determine whether the time interval (i.e., the third time interval) between the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to the first time threshold. If the third time interval is greater than or equal to the first time threshold, and the second time interval is greater than or equal to the first time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the first mode.

[0252] Optionally, the time domain position of the second uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the second uplink resource; the time domain position of the third uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the third uplink resource; the time domain position of the first downlink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the first downlink resource; and the time domain position of the fourth uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the fourth uplink resource.

[0253] Optionally, the first time threshold here can be found in the description above, and will not be repeated here.

[0254] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to a second time threshold, then the transmission mode of the beam report is the first mode.

[0255] It should be noted that before the terminal device transmits the beam report, the network device or terminal device can determine the time-domain positions of the second uplink resource, the third uplink resource, the fourth uplink resource, and the first downlink resource. Specifically, the time-domain position of the third uplink resource precedes the time-domain positions of the first downlink resource and the second uplink resource; the time-domain position of the fourth uplink resource precedes the time-domain position of the second uplink resource; and the time-domain position of the first downlink resource precedes the time-domain position of the second uplink resource. Furthermore, this condition introduces a second time threshold.

[0256] It is worth noting that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources. When the third uplink resource and the fourth uplink resource are different uplink resources, the terminal device may transmit the first uplink information only on the third uplink resource or the second uplink information only on the fourth uplink resource. For the network device, it needs to detect the third uplink resource and the fourth uplink resource to confirm whether there is information being transmitted.

[0257] Based on this, when the terminal device transmits the first uplink information only on the third uplink resource, the network device or terminal device can determine whether the time interval between the time domain location of the third uplink resource and the time domain location of the second uplink resource (i.e., the first time interval) is greater than or equal to a first time threshold, and whether the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource (i.e., the second time interval) is greater than or equal to a second time threshold. If the first time interval is greater than or equal to the first time threshold, and the second time interval is greater than or equal to the second time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the first mode.

[0258] When the terminal device transmits second uplink information only on the fourth uplink resource, the network device or terminal device can determine whether the time interval (i.e., the third time interval) between the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to a second time threshold. If the third time interval is greater than or equal to the first time threshold, and the second time interval is greater than or equal to the second time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the first mode.

[0259] Optionally, the time domain position of the second uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the second uplink resource; the time domain position of the third uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the third uplink resource; the time domain position of the first downlink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the first downlink resource; and the time domain position of the fourth uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the fourth uplink resource.

[0260] For example, taking the starting time domain position of the second uplink resource, the starting time domain position of the third uplink resource, or the starting time domain position of the fourth uplink resource, and the starting time domain position of the first downlink resource as an example, such as... Figure 8 As shown, the time interval between the starting time domain position of the third uplink resource or the starting time domain position of the fourth uplink resource and the time domain position of the second uplink resource is ΔT2, and ΔT2≥T B The time interval between the time domain position of the second uplink resource and the starting time domain position of the first downlink resource is ΔT3, and ΔT3 ≥ T. offset T offset This indicates the second time threshold.

[0261] Optionally, the first time threshold here can be found in the description above, and will not be repeated here.

[0262] Optional, a second time threshold may be configured or indicated by the network, or specified by a standard protocol, or may depend on the device capabilities of the terminal equipment.

[0263] Optionally, the second time threshold is determined by the demodulation time of the first downlink information and / or the processing time of the second uplink channel, where the second uplink channel is the uplink channel used to carry beam reports in the first mode. Specifically, the second uplink channel is either PUCCH or PUSCH.

[0264] For example, network configuration or standard protocols may specify a mapping table between the second time threshold and the demodulation time of the first downlink information. After determining the demodulation time of the first downlink information, the second time threshold is determined based on this mapping table and the demodulation time of the first downlink information.

[0265] For example, network configuration or standard protocols may specify a mapping table between a second time threshold and the processing time of a second uplink channel. After determining the processing time of the second uplink channel, the second time threshold is determined based on this mapping table and the processing time of the second uplink channel.

[0266] For example, the second time threshold is the sum of the demodulation time of the first downlink information and the processing time of the second uplink channel. Alternatively, the second time threshold can be the processing time of the second uplink channel.

[0267] Thus, if the time interval between the time domain position of the third uplink resource or the time domain position of the fourth uplink resource and the time domain position of the second uplink resource is greater than or equal to the first time threshold, and the time interval between the time domain position of the second uplink resource and the time domain position of the first downlink resource is greater than or equal to the second time threshold, this indicates that after the terminal device receives the first downlink information on the first downlink resource, there is a sufficient time interval to demodulate the first downlink information and process the second uplink channel, so that the terminal device can use the first mode to transmit beam reports, thereby ensuring the reliability and / or timeliness of beam report transmission.

[0268] Optionally, the demodulation time of the first downlink information may include the time required for the endpoint device to demodulate the first downlink information after receiving it on the first downlink resource in step 2 of the first mode.

[0269] Optionally, the processing time of the second uplink channel may include the time required to process the uplink channel used to carry beam reporting in the first mode. For example, the processing time of the second uplink channel may include at least one of data preparation time, encoding time, or modulation time.

[0270] Optionally, the demodulation time of the first downlink information can be configured or indicated by the network, or it can be specified by a standard protocol.

[0271] Optionally, since different terminal devices have different device capabilities, and different device capabilities may have different data processing capabilities, the demodulation time of the first downlink information can be dynamically set according to the different device capabilities of the terminal devices.

[0272] Optionally, the processing time of the second uplink channel may be configured or indicated by the network, or it may be specified by a standard protocol, or it may depend on the device capabilities of the terminal equipment.

[0273] Optionally, since different terminal devices have different device capabilities, and different device capabilities may have different data processing capabilities, the processing time of the second uplink channel can be set according to the different device capabilities of the terminal devices.

[0274] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than the first time threshold, then the transmission mode of the beam report is the second mode.

[0275] It should be noted that before the terminal device transmits the beam report, the network device or terminal device can determine the time domain location of the second uplink resource, the time domain location of the third uplink resource, the time domain location of the fourth uplink resource, and the time domain location of the first downlink resource. Specifically, the time domain location of the third uplink resource precedes the time domain locations of the first downlink resource and the second uplink resource; the time domain location of the fourth uplink resource precedes the time domain location of the second uplink resource; and the time domain location of the first downlink resource precedes the time domain location of the second uplink resource.

[0276] It is worth noting that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources. When the third uplink resource and the fourth uplink resource are different uplink resources, the terminal device may transmit the first uplink information only on the third uplink resource or the second uplink information only on the fourth uplink resource. For the network device, it needs to detect the third uplink resource and the fourth uplink resource to confirm whether there is information being transmitted.

[0277] Thus, when the terminal device transmits the first uplink information only on the third uplink resource, the network device or terminal device can determine whether the time interval (i.e., the first time interval) between the time domain location of the third uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than the first time threshold. If the first time interval is greater than or equal to the first time threshold and the second time interval is less than the first time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the second mode.

[0278] When the terminal device transmits second uplink information only on the fourth uplink resource, the network device or terminal device can determine whether the time interval (i.e., the third time interval) between the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than the first time threshold. If the third time interval is greater than or equal to the first time threshold and the second time interval is less than the first time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the second mode.

[0279] Optionally, the time domain position of the second uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the second uplink resource; the time domain position of the third uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the third uplink resource; the time domain position of the first downlink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the first downlink resource; and the time domain position of the fourth uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the fourth uplink resource.

[0280] Optionally, the first time threshold here can be found in the description above, and will not be repeated here.

[0281] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than a second time threshold, then the transmission mode of the beam report is the second mode.

[0282] It should be noted that before the terminal device transmits the beam report, the network device or terminal device can determine the time-domain positions of the second uplink resource, the third uplink resource, the fourth uplink resource, and the first downlink resource. Specifically, the time-domain position of the third uplink resource precedes the time-domain positions of the first downlink resource and the second uplink resource; the time-domain position of the fourth uplink resource precedes the time-domain position of the second uplink resource; and the time-domain position of the first downlink resource precedes the time-domain position of the second uplink resource. Furthermore, this condition introduces a second time threshold.

[0283] It is worth noting that the third uplink resource and the fourth uplink resource can be the same uplink resource or different uplink resources. When the third uplink resource and the fourth uplink resource are different uplink resources, the terminal device may transmit the first uplink information only on the third uplink resource or the second uplink information only on the fourth uplink resource. For the network device, it needs to detect the third uplink resource and the fourth uplink resource to confirm whether there is information being transmitted.

[0284] Thus, when the terminal device transmits the first uplink information only on the third uplink resource, the network device or terminal device can determine whether the time interval (i.e., the first time interval) between the time domain location of the third uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than the second time threshold. If the first time interval is greater than or equal to the first time threshold and the second time interval is less than the second time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the second mode.

[0285] When the terminal device transmits second uplink information only on the fourth uplink resource, the network device or terminal device can determine whether the time interval (i.e., the third time interval) between the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and whether the time interval (i.e., the second time interval) between the time domain location of the second uplink resource and the time domain location of the first downlink resource is less than the second time threshold. If the third time interval is greater than or equal to the first time threshold and the second time interval is less than the second time threshold, then the network device or terminal device can determine that the beam reporting transmission mode is the second mode.

[0286] Optionally, the time domain position of the second uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the second uplink resource; the time domain position of the third uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the third uplink resource; the time domain position of the first downlink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the first downlink resource; and the time domain position of the fourth uplink resource can be the start time domain position, end time domain position, intermediate time position, or any time domain position of the fourth uplink resource.

[0287] For example, taking the starting time domain position of the second uplink resource, the starting time domain position of the third uplink resource, and the starting time domain position of the first downlink resource as examples, such as... Figure 9 As shown, the time interval between the starting time domain position of the third uplink resource and the time domain position of the second uplink resource is ΔT2, and ΔT2 ≥ T. B The time interval between the time domain position of the second uplink resource and the starting time domain position of the first downlink resource is ΔT4, and ΔT4 <T offset .

[0288] Optionally, the first and second time thresholds here can be found in the description above, and will not be repeated here.

[0289] In some possible examples, the terminal device does not expect to receive the first downlink information between the first time and the time of the time domain location of the second uplink resource, where the first time is the difference between the time of the time domain location of the second uplink resource and a first time threshold.

[0290] It should be noted that the time of the second uplink resource's time domain position can be the time of its start time domain position, end time domain position, intermediate time position, or any other time domain position. Furthermore, the first time threshold here is described above and will not be repeated here.

[0291] For example, taking the time of the starting time domain position of the second uplink resource as an example, such as Figure 10 As shown in (a), the starting time domain position of the second uplink resource is T0, and the first time is T0-T. B Among them, the terminal device does not expect to be in (T0-T) B The first downlink information is received within T0.

[0292] This is because, as can be seen from the above, since the first time threshold is determined by the processing time of the first uplink channel, if the terminal device has already started processing the first uplink channel in the first time, and if the terminal device receives the first downlink information between the time of the first time and the time domain location of the second uplink resource, then the terminal device needs to abandon the current processing of the first uplink channel, thereby increasing the complexity of the terminal device.

[0293] In some possible examples, the terminal device does not expect to receive the first downlink information between the first time and the time of the time domain location of the second uplink resource, where the first time is the difference between the time of the time domain location of the second uplink resource and the second time threshold.

[0294] It should be noted that the time of the second uplink resource's time domain position can be the time of its start time domain position, end time domain position, intermediate time position, or any other time domain position. Furthermore, the second time threshold here is described above and will not be repeated here.

[0295] For example, taking the time of the starting time domain position of the second uplink resource as an example, such as Figure 10 As shown in (b), the starting time domain position of the second uplink resource is T0, and the first time is T0-T. offset Among them, the terminal device does not expect to be in (T0-T) offset The first downlink information is received within T0.

[0296] This is because, as discussed above, since the second time threshold is determined by the demodulation time of the first downlink information and / or the processing time of the second uplink channel, if the terminal device receives the first downlink information between the time of the first downlink information and the time of the second uplink resource's time domain location, the time domain location of the first uplink resource will be later than that of the second uplink resource. In this case, to transmit the beam report to the network device as quickly as possible, the terminal device will choose to send the beam report on the second uplink resource, i.e., use the second mode for beam report transmission, thereby improving the transmission efficiency and / or timeliness of the beam report. Furthermore, compared to using the first mode, using the second mode avoids the waste in step 2 of the first mode, because receiving the first uplink information is actually meaningless.

[0297] Method 3

[0298] In “Method 3”, the transmission mode of beam reporting, whether it is the first mode or the second mode, can be determined by the terminal device’s autonomous implementation.

[0299] For example, the terminal device can determine whether the beam report transmission mode is the first mode or the second mode based on the conditions mentioned in "Method 2" above. However, unlike "Method 2" above, the network device is unaware of these conditions.

[0300] For example, the terminal device can determine the beam report transmission mode as either a first mode or a second mode based on the temporal relationship between the temporal positions of the third and fourth uplink resources. Specifically, if the temporal position of the third uplink resource precedes the temporal position of the fourth uplink resource, the terminal device determines the beam report transmission mode as the first mode, thereby improving the timeliness of beam report transmission; if the temporal position of the fourth uplink resource precedes the temporal position of the third uplink resource, the terminal device determines the beam report transmission mode as the second mode, thereby also improving the timeliness of beam report transmission.

[0301] For example, terminal devices can independently determine the beam report transmission mode as either the first mode or the second mode based on their own equipment capabilities and network requirements, in order to ensure the reliability and / or timeliness of beam report transmission.

[0302] In some possible examples, since the transmission mode of beam reporting, whether it is mode one or mode two, is determined autonomously by the terminal device, the terminal device can inform the network device of its decision on whether it is mode one or mode two, so that the network device can know the transmission mode of beam reporting adopted by the terminal device and perform relevant processing accordingly.

[0303] For example, if the terminal device determines that the beam report transmission mode is the first mode, the terminal device can inform the network device of its decision to determine that it is in the first mode in step 1 of the first mode. As another example, if the terminal device determines that the beam report transmission mode is the second mode, the terminal device can inform the network device of its decision to determine that it is in the second mode in step 1 of the second mode.

[0304] For example, when sending a beam report, the terminal device also sends a second indication information. This second indication information indicates whether the beam report transmission mode is a first mode or a second mode, so that the network device can determine the beam report transmission mode used by the terminal device based on the second indication information. Alternatively, the beam report sent by the terminal device may itself carry the second indication information, which indicates whether the beam report transmission mode is a first mode or a second mode, so that the network device can determine the beam report transmission mode used by the terminal device based on the beam report.

[0305] For example, the terminal device can send a second indication message before sending the beam report. This second indication message indicates whether the beam report transmission mode is a first mode or a second mode, so that the network device can know the beam report transmission mode adopted by the terminal device based on the second indication message. Taking the interaction between the terminal device and the network device as an example, such as... Figure 11 As shown, Figure 11 This is a schematic diagram of another communication method according to an embodiment of this application, which specifically includes the following steps:

[0306] S1110. The terminal equipment determines whether the transmission mode of the beam report is the first mode or the second mode.

[0307] S1120. The terminal device sends a second indication information, which is used to indicate whether the transmission mode of the beam report is the first mode or the second mode.

[0308] Correspondingly, the network device receives the second instruction information.

[0309] In some possible examples, the second indication information is carried by a third uplink resource. For example, the third uplink resource is a PUCCH, and the second indication information is a field in the UCI used to indicate whether the beam report transmission mode is mode one or mode two.

[0310] S1130 is the same as S310, so it will not be described again.

[0311] As can be seen, this embodiment uses the second indication information to indicate to the network device whether the beam reporting transmission mode is the first mode or the second mode, so that the network device can know the beam reporting transmission mode adopted by the terminal device.

[0324] In specific implementation, the sending unit 1201 is used to perform any of the steps in the above method embodiments, and when performing actions such as sending, it can selectively call other units to complete the corresponding operations. A detailed description follows.

[0325] The transmitting unit 1201 is used to transmit a beam report according to the transmission mode of the beam report, wherein the transmission mode of the beam report is a first mode or a second mode, and the beam report is a beam report initiated by the terminal device or a beam report triggered by an event.

[0326] The first mode indicates that the beam report is transmitted on a first uplink resource, which is indicated by the network; the second mode indicates that the beam report is transmitted on a second uplink resource, which is pre-configured.

[0327] As can be seen, this embodiment can transmit beam reports according to the first uplink resource indicated by the network or the pre-configured second uplink resource, thereby realizing the transmission of beam reports and ensuring the reliability and / or timeliness of beam report transmission.

[0328] It should be noted that, Figure 12 The specific implementation of each operation in the embodiments can be found in the description of the method embodiments shown above, and will not be repeated here.

[0329] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is less than a first time threshold, then the transmission mode of the beam report is the first mode.

[0330] Among them, the third uplink resource is used to carry the first uplink information, and the first uplink information is used to request the first uplink resource from the network;

[0331] The fourth uplink resource is used to carry the second uplink information. The second uplink information is used to notify the network that the terminal device wants to or will transmit a beam report on the second uplink resource.

[0332] In some possible examples, if the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to a first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to a second time threshold, then the beam reporting transmission mode is the first mode; or,

[0333] If the time interval between the time domain location of the third uplink resource or the time domain location of the fourth uplink resource and the time domain location of the second uplink resource is greater than or equal to the first time threshold, and the time interval between the time domain location of the second uplink resource and the time domain location of the first downlink resource is greater than or equal to the first time threshold, then the transmission mode of the beam report is the first mode.

[0335] The fourth uplink resource is used to carry the second uplink information, which is used to notify the network that the terminal device wants to or will transmit a beam report on the second uplink resource.

[0336] The first downlink resource is used to carry the first downlink information, and the first downlink information is used to indicate the first uplink resource to the terminal device.
