Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment and network equipment. Background Technology

[0002] With the continuous development of communication technology, beamforming technology has been widely used to achieve efficient transmission of high-frequency signals. Beamforming technology adjusts the direction of transmitted and received signals, allowing the signals to be more concentrated on the user, thereby improving signal transmission efficiency and coverage. The effective application of beamforming technology relies heavily on precise beam adjustment.

[0003] Because wireless signals are affected by various factors during propagation, such as multipath effects and building obstruction, the actual transmission path may deviate from the expected path. To ensure the beam is accurately directed at the user, beam reports are required to provide timely feedback on the beam's signal quality. For example, the network 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, improving signal reception quality and stability.

For example, the chip system may include a chip, but may also include other discrete devices. The terminal device can be a chip, chip module, device, unit, etc., without specific limitations.

[0091] Network equipment

[0092] A network device is a device with transceiver capabilities that can be used to communicate with terminal devices.

[0093] Network devices may include means for providing wireless communication capabilities to terminal devices, such as chip systems, chips, or chip modules. For example, the chip system may include chips or other discrete devices. The network device provides services to a cell, and terminal devices within that cell can communicate with the network device through transmission resources (such as spectrum resources). This cell may be a macro cell, small cell, metro cell, micro cell, pico cell, or femto cell, etc.

[0094] In some possible examples, the network device has mobility characteristics; for example, the network device can be a mobile device. Optionally, the network device can be a satellite or a balloon station. For example, the satellite can be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device can also be a base station located on land, water, or other similar locations.

[0095] In some possible examples, network devices may include access network devices and / or devices in the core network (CN).

[0096] The access network equipment and core network equipment are described in detail below.

[0097] Access network equipment

[0098] In some possible examples, the access network device can be a RAN node in a radio access network (RAN). The RAN can consist of multiple RAN nodes (e.g., 5G-RAN nodes) that implement radio physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions.

[0099] In some possible examples, access network devices can connect to the UPF via the user plane interface N3 to transmit data from terminal devices; access network devices can establish control plane signaling connections via the control plane interface N2 and the access and mobility management function (AMF) to implement functions such as radio access bearer control.

[0100] In some possible examples, access network equipment may include, but is not limited to, 5G node base (gNB), evolved node base (eNB), wireless access point (WiFi AP), world interoperability for microwave access base station (WiMAX BS), transmission receiving point (TRP), wireless relay node, wireless backhaul node, master node (MN) in a dual connectivity architecture, secondary node (SN) in a dual connectivity architecture, and so on.

[0101] In some possible examples, the access network device can refer to a device used to communicate with a terminal device. For example, the access network device can be a base transceiver station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) system, a base station (nodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, an evolved node base (eNB) in an LTE system, a radio controller in a cloud radio access network (CRAN) scenario, or a relay station, access point, vehicle-mounted equipment, wearable device, and access network equipment in future 5G networks or future evolved PLMN networks, etc. The embodiments of this application are not limited to these.

[0102] In some possible examples, the functionality of access network equipment is divided into two parts, known as centralized unit (CU) - distributed unit (DU) separation. From a protocol stack perspective, the CU includes the Radio Resource Control (RRC) layer and Packet Data Convergence Protocol (PDCP) layer of the LTE base station, while the DU includes the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical (PHY) layer of the LTE base station. In a typical 5G base station deployment, the CU and DU are physically connected via fiber optic cable, and logically share a specially defined F1 interface for communication between them. Functionally, the CU is primarily responsible for radio resource control and configuration, inter-cell mobility management, and bearer management. The DU is primarily responsible for scheduling, physical signal generation, and transmission.

[0103] In some possible examples, the access network equipment can be a macro base station, micro base station, pico base station, small station, relay station, balloon station, etc.

[0104] Core network equipment

[0105] Core network equipment may include network elements that provide various functions. Here, "network element" can be referred to as an entity, device, apparatus, or module, etc., without specific limitations. Furthermore, for ease of understanding and explanation, the description of "network element" is omitted in some descriptions. For example, the network exposure function (NEF) network element is abbreviated as NEF. In this case, "NEF" should be understood as either a NEF network element or a NEF entity. The following omits explanations of similar cases.

[0106] For example, core network equipment may include a mobility management entity (MME), a broadcast multicast service center (BMSC), or corresponding functional entities in the 5G system, such as core network control plane (CP) or user plane (UP) network functions. The core network control plane can be understood as the core network control plane function (CPF) entity.

[0107] The following section describes the various network elements included in the core network equipment.

[0108] The session management function (SMF) is responsible for the control plane functions of terminal device session management, including the selection and control of user plane functions (UPF), Internet Protocol (IP) address allocation, session QoS management, acquisition policy and charging control (PCC) policies, etc.

[0109] The user plane function (UPF) can serve as the anchor point for protocol data unit (PDU) session connections. It is responsible for filtering data packets from terminal devices, transmitting / forwarding data, rate control, generating billing information, and providing connectivity to the data network (DN).

[0110] The policy control function (PCF) can provide configuration policy information for terminal devices, provide policy information for network control plane elements (such as SMF) to manage and control terminal devices, and generate access policies and QoS flow control policies for terminal devices.

[0111] 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.

[0112] NEF can be responsible for providing network-related status information to application services.

[0113] The Authentication Server Function (AUSF) can implement access authentication for both 3GPP and non-3GPP systems.

[0114] Unified Data Management (UDM) provides unified data management functions, including 3GPP AKA authentication, user identification, access authorization, registration, mobility, subscription, and SMS management.

[0115] 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.

[0116] 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.

[0117] Unified data management (UDM) can be responsible for the management of user identifiers, subscription data, authentication data, and user service element registration management.

[0118] 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.

[0119] The network data analytics function (NWDAF) can provide network analysis services based on request data from network services.

[0120] The network slice specific authentication and authorization function (NSSAAF) can be used to provide authentication and authorization for specific network slices.

[0121] 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 and different 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.

[0122] 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.

[0123] 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).

[0124] 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.

[0125] [Channel State Information (CSI) Framework]

[0126] The communication system has been described above. The CSI framework involved in this embodiment will be explained in detail below.

[0127] The CSI framework can include CSI resource configuration and / or CSI reporting configuration, which can be defined by the high-level parameter CSI-MeasConfig. CSI-MeasConfig can indicate (include / configure / carry) the following two high-level parameters: CSI-ResourceConfig and CSI-ReportConfig.

[0128] In addition, since CSI-ReportConfig can indicate / contain CSI-ResourceConfigId (CSI resource configuration identifier), CSI-ResourceConfig will be associated with (correspond to / map) CSI-ReportConfig through CSI-ResourceConfigId.

[0129] CSI-ReportConfig can be used to configure CSI reporting, that is, to configure CSI reports.

[0130] CSI-ResourceConfig can be used to configure resources for CSI measurements. Additionally, CSI-ResourceConfig can configure CSI-Resource-Set (CSI resource set), which can contain the most basic CSI reference signal (CSI-Reference Signal, CSI-RS) resources (CSI-RS-Resource).

[0131] The time-domain behavior of CSI reports includes periodic CSI reporting, aperiodic CSI reporting, semi-persistent CSI reporting carried on the physical uplink control channel (PUCCH), and semi-persistent CSI reporting carried on the physical uplink shared channel (PUSCH). Optionally, the time-domain behavior of CSI reports can be indicated by higher-layer parameters (such as reportConfigType).

[0132] For non-periodic CSI reports and semi-persistent CSI reports carried on the PUSCH, network devices also configure higher-layer parameters TriggerState and reportTriggerSize to work with the CSI request field in DCI (downlink control information).

[0133] For periodic CSI reports, configuring periodic CSI-RS Resource and Report parameters via RRC signaling will take effect immediately, without needing to trigger the transmission of CSI-RS and CSI reports through a MAC control element (MAC-CE) or DCI.

[0134] For semi-persistent CSI reports carried on PUCCH, if the transmission of semi-persistent CSI-RS is configured via RRC messages, the transmission of CSI-RS needs to be triggered first via MAC CE1, and then the transmission of CSI reports needs to be triggered via MAC CE2. If the transmission of periodic CSI-RS is configured via RRC messages, the transmission of CSI-RS does not need to be triggered via MAC CE1, and the transmission of CSI reports only needs to be triggered via MAC CE2.

[0135] For semi-persistent CSI reports carried on the PUSCH, if the transmission of semi-persistent CSI-RS is configured via RRC messages, the transmission of CSI-RS needs to be triggered first via MAC CE1, and then the transmission of CSI reports needs to be triggered via DCI. If the transmission of periodic CSI-RS is configured via RRC messages, the transmission of CSI-RS does not need to be triggered by MAC CE1, and the transmission of CSI reports only needs to be triggered via DCI.

[0136] It should be noted that for DCI, the DCI can be a DCI format 0_1 ​​scrambled with a semi-persistent CSI RNTI (SP-CSI-RNTI), and the CSI request field in the DCI can be associated with the corresponding trigger state through the codepoint setting. The trigger state will define its associated CSI-ReportConfig, so the CSI-ReportConfig associated with the semi-persistent CSI report on the PUSCH can be found through the trigger state.

[0137] For aperiodic CSI reports, which are triggered by DCI, the process is similar to that of semi-persistent CSI reports described above. However, unlike the DCI triggering in semi-persistent CSI reports, when the trigger state corresponding to the code point in the CSI request field of DCI format 0_1 / 0_2 is accessed, if the value of the CSI request field is zero, it indicates that the transmission of a semi-periodic CSI report is not triggered; if the value of the CSI request field is non-zero, it indicates that the aperiodic CSI report associated with the trigger state corresponding to the code point of the CSI request field is triggered.

[0138] [Beam Report Transmission Process]

[0139] The beam report transmission process of this embodiment will be described in detail below.

[0140] 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. This ensures communication quality between network 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.

[0141] 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.

[0142] 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.

[0143] In some possible examples, for a beam report initiated by the terminal device or a beam report triggered by an event, the terminal device performs 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 restrictions.

[0144] In some possible examples, the events mentioned above include at least one of the following:

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] Event 3: The signal quality of the new beam is higher than (greater than / exceeds) the threshold.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] Event 7a: The signal quality of at least one new beam is greater than a threshold compared to the signal quality of the reference signal with the worst signal quality in the active transmission configuration indicator (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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] Event 9: The signal quality of at least one new beam exceeds the signal quality of the configured reference signal 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 configured reference signal is greater than or equal to the threshold.

[0164] 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.

[0165] 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.

[0166] For beam reports initiated by terminal devices or triggered by events, the beam report transmission process can be either Mode A or Mode B. Mode A and Mode B are explained in detail below.

[0167]

Mode A

[0168] Pattern A may include the following three steps:

[0169] Step 1: The terminal device requests uplink resources from the network device for transmitting / carrying beam reports.

[0170] In step 1 of mode A, the terminal device can send a request message to the network device. This request message can be used to request uplink resources from the network for transmitting / bearing beam reports. The request message is carried by the uplink resources. Optionally, these uplink resources are pre-configured.

[0171] In this way, network devices can indicate uplink resources for transmitting / carrying beam reports to terminal devices based on request information, so as to ensure the transmission of beam reports.

[0172] In some possible examples, prior to step 1 of Mode A, the network device may configure uplink resources for transmitting / bearing request information to the terminal device via at least one of downlink control information (DCI), MAC signaling, RRC signaling, or system information. Therefore, these uplink resources may be pre-configured, network-configured, or network-indicated. For example, the network device sends a DCI to the terminal device indicating uplink resources for transmitting request information.

[0173] Furthermore, since the uplink resources used for transmitting / bearing beam reports are requested by the terminal device from the network device, the transmission of beam reports can be viewed as dynamically scheduled.

[0174] In some possible examples, the uplink resource used to transmit the request information is the physical uplink control channel (PUCCH) resource, and the request information is 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.

[0175] For example, taking the request information as SR as an example, the terminal device transmits SR on PUCCH resources. SR is used to request uplink resources from the network for transmitting beam reports.

[0176] In some possible examples, the requested information includes one or more bits.

[0177] 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.

[0178] Step 2: The network device indicates the uplink resources for transmitting beam reports to the terminal device.

[0179] In step 2 of mode A, the network device can send scheduling information to the terminal device. The scheduling information is used to indicate to the terminal device the uplink resources for transmitting beam reports. The scheduling information is carried by downlink resources.

[0180] In some possible examples, the downlink resource used to transmit / bear scheduling information is the physical downlink control channel (PDCCH), and the scheduling information is carried by the DCI. That is, the DCI is used to indicate to the terminal equipment the uplink resources used for transmitting beam reports.

[0181] 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 reports, the DCI may contain fields indicating the uplink resources used to transmit the beam report. In this case, this field represents scheduling information. For example, the DCI may instruct the terminal device to use a specific uplink channel and / or corresponding time-frequency resources to transmit the beam report. Furthermore, the DCI may also contain other parameters related to beam report transmission, such as modulation scheme and / or coding scheme.

[0182] Therefore, when the terminal device detects the DCI and decodes its fields, it can acquire uplink resources and transmit beam reports according to the corresponding parameters and / or configurations.

[0183] Step 3: The terminal device sends a beam report to the network device.

[0184] In step 3 of Mode A, 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.

[0185] The following example illustrates the temporal distribution of uplink and downlink resources in "Mode A", such as... Figure 3 As shown. In Figure 3 In this configuration, uplink resource 301, downlink resource 302, and uplink resource 303 are distributed sequentially in time. The time domain position of uplink resource 301 precedes the time domain positions of downlink resource 302 and uplink resource 303, and the time domain position of downlink resource 302 precedes the time domain position of uplink resource 303. Specifically, in step 1 of mode A, the terminal device sends a transmission request message on uplink resource 301, which requests uplink resources from the network for transmitting beam reports. In step 2 of mode A, the terminal device receives scheduling information on downlink resource 302, which instructs the terminal device to use uplink resource 303 for transmitting beam reports. In step 3 of mode A, the terminal device transmits beam reports on uplink resource 303.

[0186]

Mode B

[0187] Pattern B may include the following two steps:

[0188] 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.

[0189] In step 1 of mode B, the terminal device can send a notification message to the network device. This notification message informs the network that the terminal device wants to or will transmit a beam report on a pre-configured uplink resource, or that it will transmit a beam report on a pre-configured uplink resource. The notification message is carried by the uplink resource.

[0190] In this way, network devices can learn from notification information whether a terminal device wants to or will transmit a beam report on a pre-configured uplink resource, or network devices can learn from notification information whether a terminal device will transmit a beam report on a pre-configured uplink resource, so as to ensure the transmission of beam reports.

[0191] In some possible examples, the uplink resources used to carry / transmit notification information in step 1 of mode B may be the same as or different from the uplink resources used to carry / transmit request information in step 1 of mode A.

[0192] In some possible examples, prior to step 1 of Mode B, 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 can notify the network device via notification information that it wants or will transmit beam reports on one of these one or more uplink resources, or the terminal device can notify the network device via notification information that it will transmit beam reports on one of these one or more uplink resources.

[0193] In some possible examples, the uplink resource used to transmit notification information is a PUCCH resource, and the notification information is SR or UCI. SR or UCI is used to notify the network that the terminal device wants to or will transmit beam reports on a pre-configured uplink resource, or SR or UCI is used to notify the network that the terminal device will transmit beam reports on a pre-configured uplink resource.

[0194] For example, taking the first information as SR, the terminal device transmits SR on PUCCH resources. SR is used to notify the network that the terminal device wants or will transmit beam reports on a certain pre-configured uplink resource, or SR is used to notify the network that the terminal device will transmit beam reports on a certain pre-configured uplink resource.

[0195] In some possible examples, the notification information includes one or more bits.

[0196] 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.

[0197] In some possible examples, this embodiment can explicitly inform the terminal device of its consent to transmit beam reports on the pre-configured uplink resources. For example, after step 1 in mode B, 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 pre-configured uplink resources. Thus, the terminal device can learn from the first response message that the network device consents to its transmission of beam reports on the pre-configured uplink resources.

[0198] In some possible examples, this embodiment can implicitly inform the terminal device of its consent to transmit beam reports on the pre-configured uplink resources. For example, for a period of time after step 1 in mode B, the terminal device does not receive a second response message, which indicates that the network device does not consent to the terminal device transmitting beam reports on the pre-configured uplink resources. In this way, the terminal device can know that the network device consents to its transmission of beam reports on the pre-configured uplink resources.

[0199] Step 2: The terminal device sends a beam report to the network device.

[0200] In step 2 of Mode B, the terminal device transmits beam reports on the pre-configured uplink resources. This ensures the reliability of beam report transmission by utilizing these pre-configured uplink resources for beam report transmission.

[0201] The following example illustrates the temporal distribution of uplink resources in Mode B, such as... Figure 4 As shown. In Figure 4 In this configuration, uplink resources 401 and 402 are distributed sequentially in time, with the time domain position of uplink resource 401 preceding that of uplink resource 402. Specifically, in step 1 of mode B, the terminal device transmits notification information on uplink resource 401. This notification information informs the network that the terminal device wants to or will transmit beam reports on the pre-configured uplink resource 402, or that it will transmit beam reports on the pre-configured uplink resource 402. In step 2 of mode B, the terminal device transmits beam reports on uplink resource 402.

[0202] In summary, the main difference between Mode A and Mode B lies in the way resources are allocated: Mode A dynamically schedules the transmission of beam reports, while Mode B transmits beam reports based on pre-configured uplink resources.

[0203] The following embodiment uses the uplink resource for transmitting beam reports as the first uplink resource and the interaction between the terminal device and the network device as an example. Figure 5 As shown, Figure 5This is a schematic diagram of a communication method according to an embodiment of this application, which specifically includes the following steps:

[0204] S510. The terminal device sends a beam report based on the first uplink resource.

[0205] Correspondingly, the network device receives the beam report based on the first uplink resource.

[0206] As can be seen, to ensure that the beam can accurately point to the user, beam reports need to be transmitted to provide feedback on the beam's signal quality as quickly as possible, thereby guaranteeing the communication quality between network devices and terminal devices. Therefore, this embodiment introduces a first uplink resource and transmits beam reports based on this first uplink resource. Since the first uplink resource is configured / indicated by the network, it helps ensure the reliability of beam report transmission.

[0207] The following section will explain in detail how to determine the first uplink resource using either "Method 1" or "Method 2".

[0208] Method 1

[0209] In “Method 1”, this embodiment considers the combination of Mode A and the beam report triggering mechanism to determine the first uplink resource.

[0210] In Mode A, the terminal device can request uplink resources for transmitting reports using the request information in step 1.

[0211] In the beam report triggering mechanism, network devices can trigger beam report transmission via signaling. For example, DCI can trigger beam report transmission via the CSI request field. Specifically, when the trigger state corresponds to the code point of the CSI request field in DCI format 0_1 / 0_2, if the value of the CSI request field is zero, it means that beam report transmission is not triggered; if the value of the CSI request field is non-zero, it means that the beam report associated with the trigger state corresponding to the code point of the CSI request field is triggered.

[0212] Based on this, after the terminal device sends the request information, if the network device triggers the transmission of a beam report to the terminal device via signaling, the terminal device can consider this signaling to be a response to the request information in step 1 of mode A. This signaling is regarded as the scheduling information in step 2 of mode A. At this time, the uplink resource indicated by this signaling is the first uplink resource.

[0213] Thus, by combining Mode A with the beam report triggering mechanism, the uplink resource indicated by the signaling used to trigger beam report transmission is designated as the first uplink resource, thereby determining the first uplink resource so that beam report transmission can be achieved through the first uplink resource. Furthermore, by combining Mode A with the beam report triggering mechanism, a response to the request information in step 1 of Mode A is achieved, enabling the terminal device to determine that the network device has successfully received the request information in step 1 of Mode A.

[0214] The following embodiment uses the non-periodic CSI report triggering mechanism, which follows the CSI framework, as an example for specific explanation.

[0215] In the CSI report triggering mechanism of the CSI framework, network devices can trigger the transmission of one or more CSI reports via signaling. For example, for aperiodic CSI reports, DCI can trigger the transmission of one or more aperiodic CSI reports via the CSI request field. Specifically, when the trigger state corresponds to the code point of the CSI request field in DCI format 0_1 / 0_2, if the value of the CSI request field is zero, it indicates that the transmission of aperiodic CSI reports is not triggered; if the value of the CSI request field is non-zero, it indicates that the aperiodic CSI report associated with the trigger state corresponding to the code point of the CSI request field is triggered.

[0216] Based on this, after the terminal device sends the request information, if the network device triggers the transmission of one or more CSI reports to the terminal device via signaling, and these one or more CSI reports include beamforming reports (i.e., the signaling triggers the transmission of beamforming reports to the terminal device), then the terminal device can consider the signaling to be a response to the request information in step 1 of Mode A. This signaling is considered as scheduling information in step 2 of Mode A. At this time, the uplink resource indicated by this signaling is the first uplink resource.

[0217] Thus, by combining Mode A with the CSI report triggering mechanism of the CSI framework, the uplink resource indicated by the signaling used to trigger beam report transmission is designated as the first uplink resource, thereby determining the first uplink resource for beam report transmission. Furthermore, by combining Mode A with the CSI report triggering mechanism of the CSI framework, a response to the request information in step 1 of Mode A is achieved, enabling the terminal device to determine that the network device has successfully received the request information in step 1 of Mode A.

[0218] The following example uses the aforementioned signaling as the triggering information and the interaction between the terminal device and the network device. 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:

[0219] S610. The terminal device sends a request message, which is used to request uplink resources for transmitting beam reports.

[0220] Correspondingly, the network device receives the request information.

[0221] S620. The network device sends a trigger message, which is used to trigger the transmission of a beam report. The uplink resource indicated by the trigger message is the first uplink resource.

[0222] Correspondingly, the terminal device receives the trigger information. The trigger information is a response to the request information.

[0223] S630 is the same as S510, so it will not be described again.

[0224] It is evident that if the triggering information triggers the transmission of beam reports, then the triggering information is a response to the request information, and the uplink resource indicated by the triggering information serves as the first uplink resource, thereby transmitting the beam report through the first uplink resource and realizing the transmission of beam reports.

[0225] In some possible examples, the triggering information is carried by the DCI. For example, the triggering information includes a CSI request field and / or an uplink resource allocation field in the DCI. The CSI request field is used to trigger the transmission of one or more CSI reports, and the uplink resource allocation field is used to indicate uplink resources.

[0226] In some possible examples, the triggering information is used to trigger one or more CSI reports that contain a beam report. That is, the beam report is within one or more CSI reports that are triggered by the triggering information.

[0227] In some possible examples, each of the one or more CSI reports is an aperiodic CSI report. That is, the triggering information is used to trigger one or more aperiodic CSI reports that include beam reports. In this case, it is equivalent to the beam report being an aperiodic CSI report.

[0228] For example, the triggering information includes a CSI request field in the DCI, and the value of this CSI request field is non-zero (i.e., a non-zero CSI request field). A non-zero CSI request field is used to trigger one or more aperiodic CSI reports. In this way, the first uplink resource is determined through the aperiodic CSI report triggering mechanism.

[0229] In some possible examples, this embodiment can impose certain constraints on the terminal device for cases where the beam report is an aperiodic CSI report.

[0230] For example, if the terminal device is configured with a single uplink carrier, the terminal device expects to transmit multiple aperiodic CSI reports on overlapping orthogonal frequency division multiplexing (OFDM) symbols; wherein the multiple aperiodic CSI reports include beam reports, the multiple aperiodic CSI reports are triggered by multiple DCIs, and the multiple DCIs include at least one DCI for carrying triggering information. Optionally, the multiple aperiodic CSI reports may include only one aperiodic CSI report that does not include beam reports.

[0231] It is understood that if the terminal device is configured with a single uplink carrier, multiple DCIs for triggering the transmission of multiple aperiodic CSI reports, the multiple DCIs including at least one DCI for carrying trigger information, and the multiple aperiodic CSI reports including beam reports, then the terminal device can transmit the multiple aperiodic CSI reports on overlapping OFDM symbols. Optionally, the multiple aperiodic CSI reports may include only one aperiodic CSI report with a non-beam report.

[0232] Thus, the first uplink resource is an overlapping Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0233] For example, the terminal device expects to receive multiple DCIs in each time slot of the cell, the multiple DCIs including at least one DCI for carrying trigger information, and at least one of the multiple DCIs including a non-zero CSI request field.

[0234] It is understood that if multiple DCIs include at least one DCI for carrying triggering information, and at least one of the multiple DCIs contains a non-zero CSI request field, then the terminal device can receive the multiple DCIs in each time slot of the cell. These multiple DCIs can trigger multiple aperiodic CSI reports, and these multiple aperiodic CSI reports include beamforming reports. Optionally, the multiple aperiodic CSI reports may contain only one aperiodic CSI report with a non-beamforming report.

[0235] In this way, the triggering information is carried by the DCI, which is transmitted in each time slot of the cell.

[0236] For example, a terminal device may expect to receive multiple transmission request messages within a time slot of a cell. These multiple transmission request messages are used to request the transmission of an aperiodic CSI report, and the multiple transmission request messages include at least one transmission request message for requesting the transmission of a beam report.

[0237] It is understood that if multiple transmission request messages are used to request the transmission of aperiodic CSI reports, and the multiple transmission request messages include at least one transmission request message for requesting the transmission of beam reports, then the terminal device can receive the multiple transmission request messages within one time slot of the cell.

[0238] Thus, the beam report is transmitted by a transmission request message, which is transmitted within a time slot of the cell.

[0239] Method 2

[0240] In "Method 2", this embodiment considers determining the first uplink resource in the scenario of cross-carrier (CC) beam reporting. The following provides examples illustrating the possible meanings of cross-carrier beam reporting.

[0241] One possible interpretation is that cross-carrier beam reporting refers to a beam report associated with measurement resources that originate from / correspond to a cell / carrier different from the cell / carrier in which the beam report is located. In other words, the cell / carrier corresponding to the measurement resources associated with a beam report is different from the cell / carrier in which the beam report is located.

[0242] In other words, the measurement resources associated with a beam report come from / correspond to one or more cells / beams, which may not include the cell / carrier where the beam report is located.

[0243] For example, if the cell where the beam report is located is cell 1, the cell corresponding to the measurement resource associated with the beam report of cell 1 is cell 2.

[0244] Thus, for Figure 5 In S510, when the terminal device sends a beam report based on the first uplink resource, the cell corresponding to the measurement resource associated with the beam report is different from the cell / carrier in which the beam report is located. This beam report is a cross-carrier beam report.

[0245] In this context, the measurement resource associated with a beam report can be understood as the beam measurement results carried by the beam report being obtained by measuring based on that measurement resource.

[0246] In this context, the cell corresponding to the measurement resource associated with a beam report can be understood as the measurement resource associated with that beam report belonging to that cell.

[0247] In this context, the cell / carrier in which a beam report resides can be understood as the cell / carrier in which the beam measurement results carried in the beam report are obtained by measuring the measurement resources of that cell / carrier; or, it can be understood as the configuration information corresponding to the beam report being the configuration information of that cell / carrier. This configuration information can include measurement configuration information and / or reporting configuration information. The measurement configuration information can be used to configure measurement resources, and the reporting configuration information can be used to configure the reporting of beam reports.

[0248] In this context, a beam report for a cell / carrier can be understood as the beam measurement results carried in the beam report being obtained by measuring the measurement resources of that cell / carrier; or, it can be understood as the serving cell / carrier in which the beam report is located; or, it can be understood as the configuration information corresponding to the beam report being the configuration information belonging to that cell / carrier.

[0249] One possible interpretation is that cross-carrier beam reporting refers to a beam report from one cell / carrier being reported in a different cell (i.e., another cell). In other words, a beam report from one cell / carrier is transmitted in a different cell (i.e., another cell).

[0250] For example, the beam report of cell 1 is reported in cell 2.

[0251] One possible interpretation is that cross-carrier beam reporting refers to beam reports from different cells / carriers being reported within the same cell. In other words, beam reports from one or more cells / carriers are transmitted within the same cell.

[0252] Optionally, the same cell can be one of the multiple cells. In this case, beam reports of all or some of the cells in the multiple cells are transmitted within one of the cells. The terminal device then needs to send beam reports of all or some of the cells in the multiple cells based on the uplink resources of that specific cell.

[0253] For example, taking the multiple cells as cell 1, cell 2, and cell 3, the beam reports of cell 1, cell 2, and cell 3 are transmitted within one of the cells 1, 2, or 3. In this case, the terminal device sends the beam reports of cell 1, 2, and 3 based on the uplink resources of one of the cells 1, 2, or 3. Thus, for Figure 5 In the S510, when the terminal device sends a beam report based on the first uplink resource, the cell / carrier where the first uplink resource is located is one of the cells / carriers in which the beam report is located (such as cell 1, cell 2 and cell 3 in this example).

[0254] For example, taking the multiple cells as cell 1, cell 2, and cell 3, the beam reports of cell 1 and cell 2 are transmitted within cell 2. At this time, the terminal device sends the beam reports of cell 1 and cell 2 based on the uplink resources of cell 2. Thus, for Figure 5In S510, when the terminal device sends a beam report based on the first uplink resource, the cell / carrier where the first uplink resource is located (such as cell 2 in this example) is one of the cells / carriers where the beam report is located (such as cell 1 and cell 2 in this example).

[0255] For example, taking the multiple cells as cell 1, cell 2, and cell 3, the beam reports of cell 1 and cell 2 are transmitted within cell 3. In this case, the terminal device sends the beam reports of cell 1 and cell 2 based on the uplink resources of cell 3. Thus, for Figure 5 In the S510, the terminal device sends a beam report based on the first uplink resource. The cell / carrier where the first uplink resource is located (such as cell 3 in this example) is different from the cell / carrier where the beam report is located (such as cell 1 and cell 2 in this example).

[0256] For example, taking the multiple cells as cell 1, cell 2, and cell 3, the beam report of cell 1 is transmitted within cell 3. In this case, the terminal device sends the beam report of cell 1 based on the uplink resources of cell 3. Thus, for... Figure 5 In S510, when the terminal device sends a beam report based on the first uplink resource, the cell / carrier where the first uplink resource is located (such as cell 3 in this example) is not used for the cell / carrier where the beam report is located (such as cell 1 in this example).

[0257] Optionally, the same cell may not be within one or more cells. In this case, beam reports for the multiple cells are transmitted in other cells besides the multiple cells mentioned above. The terminal device then needs to send beam reports for the multiple cells based on the uplink resources of those other cells.

[0258] For example, a cell is cell 1, and the beam report of cell 1 is transmitted in cell 2.

[0259] For example, taking the multiple cells as cell 1, cell 2, and cell 3, the beam reports of cell 1, cell 2, and cell 3 are transmitted within cell 4. At this time, the terminal device sends the beam reports of cell 1, cell 2, and cell 3 according to the uplink resources of cell 4.

[0260] Thus, for Figure 5 In the S510, if the terminal device sends a beam report based on the first uplink resource, the cell / carrier where the first uplink resource is located is not within the cell / carrier where the beam report is located, or in other words, the cell / carrier where the first uplink resource is located is different from the cell / carrier where the beam report is located.

[0261] Based on the above, in the scenario of cross-carrier beam reporting, this embodiment will be specifically explained using the cell where the first uplink resource is located as the first cell. Here, the first uplink resource can be the uplink resource of the first cell, and the first cell can be one of one or more cells. In this case, for Figure 5 In the S510, the terminal device transmits a beam report based on the uplink resources of the first cell.

[0262] In some possible examples, if the terminal device transmits a beam report based on the uplink resources of a first cell, and the first cell is one of one or more cells, then the cell in which the beam report is located is different from the first cell.

[0263] For example, the first cell is cell 1, and the cell where the beam is located is cell 2.

[0264] In some possible examples, where beam reports from different cells / carriers are reported within the same cell, if the terminal device transmits the beam report based on the uplink resources of the first cell, and the first cell is one of one or more cells, then the beam report includes beam reports from all of those one or more cells. In this case, the beam reports from those one or more cells are reported within the first cell.

[0265] For example, taking one or more cells including cell 1, cell 2, and cell 3, with cell 1 as the first cell, the beam reports of cell 1, cell 2, and cell 3 are transmitted within cell 1. That is, the terminal device sends the beam reports of cell 1, cell 2, and cell 3 based on the uplink resources of cell 1.

[0266] In some possible examples, where beam reports from different cells / carriers are reported within the same cell, if the terminal device transmits a beam report based on the uplink resources of a first cell, and the first cell is one of one or more cells, then the beam report includes beam reports from the other cells besides the first cell. In this case, the beam reports from the other cells are reported within the first cell.

[0267] For example, taking one or more cells including cell 1, cell 2, and cell 3, with cell 1 as the first cell, the beam reports of cell 2 and cell 3 are transmitted within cell 1. That is, the terminal device sends the beam reports of cell 2 and cell 3 based on the uplink resources of cell 1.

[0268] In some possible examples, where beam reports from different cells / carriers are reported within the same cell, if the terminal device transmits the beam report based on the uplink resources of a first cell, and the first cell is one of one or more cells, then the beam report includes beam reports from a portion of those one or more cells. In this case, that portion of the beam report is reported within the first cell.

[0269] For example, taking one or more cells including cell 1, cell 2, and cell 3, with cell 1 as the first cell, the beam report for cell 2 is transmitted within cell 1. That is, the terminal device sends the beam report for cell 2 based on the uplink resources of cell 1. In some possible examples, the uplink resources of the first cell can be the PUCCH resources or PUSCH resources of the first cell. Thus, the beam report is carried through the PUCCH or PUSCH of the first cell.

[0270] In some possible examples, the first cell is the cell with the smallest cell index within the one or more cells. In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the smallest cell index, achieving cross-carrier beam reporting.

[0271] In some possible examples, the first cell is the cell with the largest cell index among one or more cells. In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the largest cell index, thereby achieving cross-carrier beam reporting.

[0272] In some possible examples, the first cell is any one of one or more cells.

[0273] In this way, the terminal device can transmit beam reports based on the uplink resources of any cell, thus achieving cross-carrier beam reporting.

[0274] In some possible examples, the first cell is the cell with the smallest cell index in the first cell set, which is a set of cells with the smallest subcarrier spacing among one or more cells.

[0275] In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the smallest index in the cell with the smallest subcarrier spacing.

[0276] In some possible examples, the first cell is the cell with the largest cell index in the first cell set, which is the set of cells with the smallest subcarrier spacing among one or more cells.

[0277] In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the largest index in the cell with the smallest subcarrier spacing.

[0278] In some possible examples, the first cell is the cell with the smallest cell index in the second cell set, which is a set of one or more cells with the largest subcarrier spacing.

[0279] In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the smallest index in the cell with the largest subcarrier spacing.

[0280] In some possible examples, the first cell is the cell with the largest cell index in the second cell set, which is a set of cells with the largest subcarrier spacing among one or more cells.

[0281] In this way, the terminal device can transmit beam reports based on the uplink resources of the cell with the largest index in the cell with the largest subcarrier spacing.

[0282] In some possible examples, each of the one or more cells is either an active cell or an inactive cell.

[0283] In some possible examples, each of the one or more cells is a serving cell. For example, the one or more cells are serving cells under dual connectivity (DC) or carrier aggregation (CA).

[0284] In some possible examples, the one or more cells belong to the same cell list, or the same cell group, or the same cell cluster.

[0285] It should be noted that for a cell list, if the MAC updates the TCI state of a certain bandwidth part Identifier (BWP ID) of a cell in the cell list, it means that the TCI state of the same BWP ID of other cells in the cell list has also been updated accordingly.

[0286] Optionally, the same cell group can be a master cell group (MCG) or a secondary cell group (SCG).
