Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0027] The network device in this application embodiment can be a device used to communicate with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0031] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0032] Near Field Communication

[0033] In future communication systems (such as 6G systems), larger antenna apertures and higher frequency bands (e.g., centimeter waves, millimeter waves, terahertz, etc.) are likely to be adopted, making near-field characteristics more pronounced. Furthermore, the introduction of emerging technologies such as reconfigurable intelligent surfaces (RIS), massive MIMO, movable antennas, and cell-free networks will also make near-field scenarios more prevalent in future communication systems. In near-field communication scenarios, due to changes in the propagation characteristics of electromagnetic waves, the wavefront can no longer be simply approximated as a plane wave but must be considered as a spherical wave. From the perspective of space resource utilization, although traditional wireless communication systems have achieved significant success in the exploration and utilization of far-field space resources, further exploration and application of near-field space resources are expected to bring new physical space dimensions to wireless communication systems.

[0034] The division between the near-field and far-field regions can be determined using the following method: The range is the far field. The range is the near-field of radiation. Here, r represents the radiation radius, D represents the antenna aperture, and λ represents the wavelength.

[0035] In some embodiments, in far-field communication, the electromagnetic wave front can be approximated as a plane wave. In some embodiments, in near-field communication, the electromagnetic wave front can be considered as a spherical wave.

[0036] Beamforming is a technique that uses an antenna array to direct wireless signals to a specific receiver. Beamforming improves the quality, capacity, and reliability of wireless communication by generating constructive useful signals or destructive interference at the receiver by transmitting signals with different amplitudes and phases from different antennas. However, in far-field wireless communication systems, because the electromagnetic wavefront is planar, beamforming can only control signal propagation in one dimension: angle (direction). Unlike far-field communication, in near-field communication environments, by utilizing the propagation characteristics of spherical waves, near-field beamforming (beam focusing) technology can focus signal energy at a specific location in space, achieving control over signal propagation in both angular and distance dimensions.

[0037] Beam reporting

[0038] The terminal device can report K (K>=1) pieces of information to the network device based on the measurement results. Each of the K pieces of information includes beam indication information and the Layer 1 measurement result corresponding to the beam indication information. This application embodiment does not limit the beam indication information; for example, the beam indication information may include one or more of the following: a channel state information reference signal (CSI-RS) resource identifier, and a synchronization signal block (SSB) number.

[0039] This application does not limit the measurement results of Layer 1. Exemplarily, the measurement results of Layer 1 may include one or more of the following: the reference signal receiving power (RSRP) of Layer 1, and the signal to interference plus noise ratio (SINR) of Layer 1. Hereinafter, the RSRP of Layer 1 will be referred to as L1-RSRP, and the SINR of Layer 1 will be referred to as L1-SINR.

[0040] Using L1-RSRP as a measurement has the following advantages: L1-RSRP measurement is simple, low in complexity, and easy to implement in terminal equipment. L1-RSRP measurements primarily reflect the channel quality corresponding to the downlink beam, and its changes are relatively slow, facilitating the relatively stable selection of a reliable downlink beam. Conversely, the interference corresponding to the downlink beam changes rapidly; that is, L1-SINR is more volatile, and using it for beam measurement may lead to frequent beam switching. In MIMO transmission schemes, CSI feedback already reflects interference-related characteristics; therefore, beam management based on L1-RSRP combined with CSI feedback can achieve the same purpose as L1-SINR. Compared to L1-RSRP, the additional gain provided by L1-SINR is not significant, and in some cases may even lead to performance loss.

[0041] Using L1-SINR as a measurement has the following advantages. The quality of downlink beam reception depends not only on the corresponding channel quality but also on interference. L1-RSRP cannot truly reflect beam transmission quality; therefore, L1-SINR-based measurements can better account for beam interference. Using L1-RSRP measurement and CSI feedback together requires two separate processes: beam management and CSI measurement feedback. Using L1-SINR, terminal device pairing can be completed in a single process. L1-SINR can assist network devices in coordinating downlink transmission beams used by different cells or different TRPs, thereby improving overall system performance.

[0042] In some embodiments, when K>1, the terminal device can directly report the quantized result of the maximum value among the K L1-RSRP values, and report the quantized differences between the other K-1 L1-RSRP values ​​and the maximum L1-RSRP value, i.e., the difference values ​​of the other K-1 L1-RSRP values ​​are reported. The terminal device also adopts a similar reporting method for L1-SINR measurement.

[0043] Depending on whether the terminal device can receive data transmitted simultaneously on K downlink beams, the reporting methods for beam measurement results can be divided into the following two categories: non-group based reporting and group based reporting.

[0044] In non-group-based reporting, the terminal device can perform measurements based on N reference signals configured by the network device, and select K reference signals to report based on the measurement results. The value of K is configured by the network device; for example, K can be configured as one of the following: 1, 2, 3, or 4. These K reference signals correspond to K beams. The network device cannot simultaneously transmit signals to the terminal device through multiple beams from these K beams because the terminal device cannot simultaneously receive signals transmitted on multiple downlink beams. When reporting the information of the K reference signals, the terminal device can select K from the N reference signals according to its implementation algorithm. For example, the terminal device can consider only the K reference signals with the strongest Layer 1 RSRP. Another example is that the terminal device can consider the direction of arrival of different beams (i.e., consider the spatial correlation between different received reference signals) to select K reference signals. Yet another example is that the terminal device can simultaneously consider the direction of arrival of different beams and the Layer 1 RSRP to select K reference signals. After the terminal equipment determines the K reference signals to be reported, it can report downlink beams by reporting up to 4 CSI-RS resource indicators (CRI) or SSB resource indicators (SSBRI).

[0045] In group-based reporting, the terminal device needs to be able to simultaneously receive multiple downlink transmit beams. When the network device configures the terminal device to perform group-based reporting, the terminal device can perform measurements based on N reference signals configured by the network device, and select to report K (K=2) pieces of information based on the measurement results. Each of these K pieces of information includes indication information of the reference signal (e.g., CSI-RS resource identifier, SSB number) and the corresponding measurement result (e.g., L1-RSRP information). The network device can simultaneously transmit data with the terminal device from the reported K (K=2) beams.

[0046] For ease of understanding, the following section describes the content reported by the terminal device in the group-based downlink beam reporting method, as shown in Table 1.

[0047] Table 1

[0048] As can be seen from Table 1, when K>1, the terminal device can directly report the quantization result of the maximum value among the K L1-RSRP values, and report the difference between the other K-1 L1-RSRP values ​​and the maximum L1-RSRP value after quantization, that is, the difference value of the other K-1 L1-RSRP values.

[0049] In the example in Table 1, the network device can transmit data with the terminal device simultaneously on both beams of the first resource group, or the network device can transmit data with the terminal device simultaneously on both beams of the second resource group, etc.

[0050] In traditional beam management processes, in order to obtain the best or preferred beams in real time for data or control signaling transmission, network devices may configure or activate frequent periodic or semi-persistent beam reporting (e.g., the best k beams and their corresponding L1-RSRPs) or trigger frequent aperiodic beam reporting, which can lead to significant uplink reporting overhead and control signaling overhead.

[0051] For beam reporting of layer 1 / layer 2 triggered mobility (LTM), the terminal device can report L cells, and for each cell, report the SSBRI of M beams and the corresponding measurement results (such as L1-RSRP information). The reporting method of the terminal device for LTM is given below with reference to Table 2.

[0052] Table 2

[0053] During LTM, the terminal device reports one or more reference signals of the candidate cell and the corresponding L1-RSRP. The network device then switches the serving cell of the terminal device based on the measurement report reported by the terminal.

[0054] Configuration and indication of the Transmission Configuration Indicator (TCI) status

[0055] The configuration and indication of TCI status includes three steps: radio resource control (RRC) configuration, medium access control control element (MAC CE) activation, and downlink control information (DCI) indication. The process is described below.

[0056] RRC can configure up to M TCI states for a terminal device through the configuration information PDSCH-Config. The value of M is determined by the capabilities of the terminal device, and the maximum value of M can be 128.

[0057] The MAC CE can activate up to eight TCI state groups for mapping to the 3-bit TCI information field in the DCI. Each TCI state group activated by the MAC CE can contain one or two TCI states. For example, each TCI state group activated by the MAC CE can include a unified TCI state. As another example, each TCI state activated by the MAC CE can include an uplink TCI state and a downlink TCI state.

[0058] DCI can indicate a DCI state from the TCI state activated by the MAC CE for use by the terminal device.

[0059] In some embodiments, if the higher-level parameter configuration DCI includes a TCI indication field, DCI format 1_1 can indicate a TCI status group from the TCI status group activated by the MAC CE; if the higher-level parameter configuration DCI does not include a TCI indication field or the data is scheduled through DCI format 1_0, the DCI will not include a TCI status indication field.

[0060] A TCI state can contain the following configurations: TCI state identifier (ID), quasi-co-location (QCL) information 1, and QCL information 2. The TCI state identifier can be used to identify a TCI state. A QCL information can contain the following information: QCL type configuration and QCL reference signal configuration.

[0061] QCL type configuration can include one of QCL type A, QCL type B, QCL type C, and QCL type D. The definitions of different QCL type configurations are as follows: QCL type A: {Doppler shift, Doppler spread, average delay, delay spread}; QCL type B: {Doppler shift, Doppler spread}; QCL type C: {Doppler shift, average delay}; QCL type D: {spatial Rx parameter}.

[0062] QCL reference signal configuration may include the cell ID where the reference signal is located, the bandwidth part (BWP) ID, and the reference signal information. This reference signal information can be a CSI-RS resource ID or an SSB index.

[0063] As described above, the introduction of ultra-large-scale MIMO arrays into future communication systems may lead to near-field effects. In this scenario, the channel, angle, and range domains of the antenna arrays of terminal and network devices become correlated. Therefore, how the terminal device performs beam reporting in this situation is a problem that needs to be addressed. For example, how the terminal device performs beam reporting during mobility is a problem that needs to be solved.

[0064] To address the aforementioned issues, the inventors discovered that in the scenario of ultra-large-scale MIMO arrays, if the antenna array of the network device is divided into multiple antenna groups, the communication between each antenna group and the terminal device can still be approximated as a far-field channel (i.e., far-field communication), which can reduce the complexity of beam reporting. For example, as shown in Figure 2, in an ultra-large-scale MIMO array, the embodiments of this application can divide the antenna array of the network device into multiple antenna groups (antenna group 1, antenna group 2, antenna group 3, and antenna group 4 as shown in Figure 2). In this way, when the terminal device communicates with the network device, the terminal device can communicate with the network device through one or more of the aforementioned antenna groups. In this scenario, the communication between each antenna group of the terminal device and the network device can also be approximated as near-field communication.

[0065] Therefore, in scenarios where the antenna array of network equipment is divided into multiple antenna groups, how terminal equipment should perform beam reporting during mobility remains a problem that needs to be solved.

[0066] Based on this, this application proposes that a terminal device can report measurement information (i.e., beam measurement information) of one or more antenna groups to a network device. In other words, the terminal device can report beam measurement information at the granularity of antenna groups, which improves the success rate of handover during mobility and reduces the measurement and reporting overhead of the terminal device. The following describes the method embodiments of this application.

[0067] Figure 3 is a flowchart of a wireless communication method provided in an embodiment of this application. The method shown in Figure 3 is described from the perspective of interaction between a terminal device and a network device, which can be, for example, the terminal device 120 and the network device 110 shown in Figure 1. The method shown in Figure 3 may include step S310, which will be described below.

[0068] In step S310, the terminal device sends a measurement report to the network device.

[0069] In this embodiment, the measurement report can be used to report measurement information of one or more antenna groups associated with one or more candidate cells. Alternatively, the measurement report can be used to report measurement results of one or more antenna groups, or it can be used to report measurement information of some or all antenna groups associated with one or more candidate cells. In other words, in this embodiment, when the terminal device reports measurement information, it does not report directly at the candidate cell level, but at the antenna group level of the candidate cell. This finer granularity is beneficial for the network device to determine which antenna group of the target cell the terminal device should hand over to based on the reported measurement information. This improves the success rate of handover during movement, or in other words, it helps ensure the communication quality after the terminal device hands over to the target cell.

[0070] In some embodiments, the term "antenna group" mentioned in this application can be understood or referred to as one or more of the following: antenna group, one or more antenna ports, antenna port group, reference signal set, reference signal resource set, reference signal, and reference signal resource. Each reference signal set or each reference signal resource set may correspond to a different antenna group. Each reference signal or each reference signal resource may be configured with one or more antenna ports. Each reference signal or each reference signal resource may correspond to one antenna group.

[0071] This application does not limit the reference signal set or reference signal resource set. Exemplarily, the reference signal set or reference signal resource set may include one or more of the following: a CSI-RS set (or a CSI-RS resource set), an SSB set (or an SSB resource set), a tracking reference signal (TRS) set (or a TRS resource set), and a sensing reference signal (SRS) set (or an SRS resource set).

[0072] This application does not limit the reference signal or reference signal resource. For example, the reference signal or reference signal resource may include one or more of the following: CSI-RS (or CSI-RS resource), SSB (or SSB resource), TRS (or TRS resource), SRS (or SRS resource).

[0073] In some embodiments, the antenna group allocation of the network device can be determined based on the measurement results of reference signals reported by the terminal device. As one implementation, the network device can configure various port configuration reference signals to the terminal device. After measuring these reference signals, the terminal device reports the measurement results to the network device. Then, the network device can determine the antenna group allocation based on the measurement results of the reference signals reported by the terminal device.

[0074] In some embodiments, the measurement information (or measurement results) of the one or more antenna groups includes the beam measurement information (or layer 1 measurement information, layer 1 measurement results, beam measurement results, beam indication information) of the one or more antenna groups. That is, the measurement report of the embodiments of this application can be used by the terminal device to report the beam measurement information of one or more antenna groups.

[0075] In some embodiments, the measurement information of the one or more antenna groups is associated with one or more candidate cells. Alternatively, the one or more antenna groups are some or all of the antenna groups associated with one or more candidate cells that the terminal device needs to measure.

[0076] For example, the measurement information of one or more antenna groups reported by the terminal device represents a portion of the antenna groups associated with one or more candidate cells that the terminal device needs to measure. In other words, the terminal device does not need to report all antenna groups associated with each candidate cell; it can report only a portion of the antenna groups associated with each candidate cell. Similarly, the terminal device may not need to report all candidate cells configured by the network device, but only select one or more candidate cells from the network device's configuration and report the measurement information of the portion of antenna groups associated with those candidate cells. Reporting the measurement information of a portion of the antenna groups associated with one or more candidate cells helps reduce the measurement and reporting overhead of the terminal device.

[0077] For example, the measurement information of one or more antenna groups reported by the terminal device refers to all antenna groups associated with one or more candidate cells that the terminal device needs to measure. In other words, the terminal device needs to report all antenna groups associated with each candidate cell. Of course, the terminal device may not need to report all candidate cells configured by the network device, but only select one or more candidate cells from all candidate cells configured by the network device and report the measurement information of all antenna groups associated with those one or more candidate cells.

[0078] In some embodiments, the terminal device may report measurement information of one antenna group in each of one or more candidate cells.

[0079] In some embodiments, the terminal device may report measurement information of multiple antenna groups in each of one or more candidate cells.

[0080] In some embodiments, network devices can configure the number of candidate cells that a terminal device can measure and / or which candidate cells to measure via higher-layer signaling (such as RRC signaling). In some embodiments, network devices can configure the number of candidate cells that a terminal device needs to report via higher-layer signaling (such as RRC signaling). In this case, after measuring the candidate cells that need to be measured, the terminal device can determine which candidate cells' measurement information needs to be reported based on the number of candidate cells to be reported.

[0081] The measurement information will be introduced below.

[0082] This application does not limit the measurement information, or in other words, this application does not limit the measurement quantity corresponding to the measurement information. For example, the measurement information may include one or more of the following: RSRP, reference signal receiving quality (RSRQ), received signal strength indication (RSSI), SINR, signal-to-noise ratio (SNR), and block error rate (BLER) of the physical downlink control channel (PDCCH).

[0083] In some embodiments, the measurement information may include one of the above-described methods. As an example, the measurement information may include RSRP. As another example, the measurement information may include RSRQ. As yet another example, the measurement information may include RSSI. As yet another example, the measurement information may include SINR. As yet another example, the measurement information may include SNR. As yet another example, the measurement information may include the BLER of the PDCCH.

[0084] In some embodiments, the measurement information may include multiple of those described above. As an example, the measurement information may include RSRP and RSRQ. As another example, the measurement information may include RSRP and SINR. As yet another example, the measurement information may include RSRP and SNR. As yet another example, the measurement information may include RSRP and the BLER of the PDCCH. As yet another example, the measurement information may include RSRP, RSSI, and SINR. As yet another example, the measurement information may include RSRQ, SINR, and the BLER of the PDCCH. As yet another example, the measurement information may include RSRP, SINR, RSSI, and the BLER of the PDCCH. It should be noted that the examples listed here are merely illustrative; for the sake of brevity, other combinations are not listed.

[0085] In some embodiments, the measurement information may include measurement information of layer 1. For example, the measurement information may include one or more of L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, SNR, and BLER of PDCCH.

[0086] In some embodiments, the measurement information may include absolute measurement values ​​and / or differential values, which are relative to a reference value. In some embodiments, an absolute measurement value may also be understood as an absolute value, and a differential value may also be understood as a relative measurement value, difference, etc. For example, the terminal device may report the absolute measurement value of the reference signal corresponding to each antenna group in the measurement report. As another example, the terminal device may report the absolute measurement value of the reference signal corresponding to a certain antenna group as a reference value in the measurement report, while other measurement values ​​are differential values ​​relative to that reference value. As yet another example, the terminal device may report the absolute measurement values ​​of the reference signals corresponding to some antenna groups in the measurement report, while the measurement values ​​of the reference signals corresponding to other antenna groups are reported in the form of a reference value and a differential value.

[0087] This application does not limit the reference value corresponding to the differential value. The reference value can be measurement information determined according to specific rules. For example, the reference value may include one of the following: the maximum value among the measurement information corresponding to one or more reported antenna groups, the minimum value among the measurement information corresponding to one or more reported antenna groups, and the measurement information of the first reference signal corresponding to the antenna group with the smallest identifier reported by the candidate cell with the smallest identifier among one or more reported candidate cells.

[0088] As an example, the reference value can include the maximum value of the measurement information corresponding to one or more reported antenna groups. That is, the reference value can be the maximum value of the measurement information of all reported antenna groups in all candidate cells reported by the terminal device.

[0089] As another example, the reference value can include the minimum value among the measurement information corresponding to one or more reported antenna groups. That is, the reference value can be the minimum value of the measurement information among all reported antenna groups in all candidate cells reported by the terminal device.

[0090] As yet another example, the reference value may include the measurement information of the first reference signal corresponding to the antenna group with the smallest identifier reported by the candidate cell with the smallest identifier from one or more reported candidate cells.

[0091] It should be noted that the method for determining the reference value is not limited to the methods listed above, as long as the reference value is measurement information determined according to specific rules. For example, the reference value may include the measurement information of the first reference signal corresponding to the antenna group with the largest identifier reported by one or more candidate cells.

[0092] In some embodiments, if the measurement information includes differential values, the terminal device may indicate one or more of the following information in the measurement report: the identifier of the candidate cell where the reference value is located, and the identifier of the antenna group where the reference value is located. That is, if the measurement information is reported in the form of reference values ​​and differential values, the terminal device may indicate the candidate cell and / or antenna group where the reference value is located in the measurement report. For example, the terminal device may indicate the candidate cell and antenna group where the reference value is located in the measurement report.

[0093] In some embodiments, the terminal device may determine the measurement information before sending a measurement report (or reporting measurement information). This application does not limit the method for determining the measurement information. Exemplarily, the measurement information may be determined based on one or more of the following: the identifiers of one or more candidate cells, information about the antenna group of each candidate cell, a reference signal corresponding to the antenna group of each candidate cell, and the TCI state corresponding to the antenna group of each candidate cell.

[0094] In some embodiments, the measurement information can be determined based on one of the information described above. As an example, the measurement information can be determined based on the identifiers of one or more candidate cells. As another example, the measurement information can be determined based on the antenna group information of each candidate cell. As yet another example, the measurement information can be determined based on the reference signal corresponding to the antenna group of each candidate cell. As yet another example, the measurement information can be determined based on the TCI state corresponding to the antenna group of each candidate cell.

[0095] In some embodiments, the measurement information can be determined based on a variety of the information described above. As an example, the measurement information can be determined based on the identifiers of one or more candidate cells and the antenna group information of each candidate cell. As another example, the measurement information can be determined based on the antenna group information of each candidate cell and the reference signal corresponding to the antenna group of each candidate cell. As yet another example, the measurement information can be determined based on the antenna group information of each candidate cell and the TCI state corresponding to the antenna group of each candidate cell. As yet another example, the measurement information can be determined based on the identifiers of one or more candidate cells, the antenna group information of each candidate cell, and the reference signal corresponding to the antenna group of each candidate cell. As yet another example, the measurement information can be determined based on the identifiers of one or more candidate cells, the antenna group information of each candidate cell, and the TCI state corresponding to the antenna group of each candidate cell. It should be noted that the above are merely examples; for simplicity, other combinations are not listed.

[0096] In some embodiments, the identifiers of the one or more candidate cells can be used to determine which candidate cells the terminal device needs to measure and / or which candidate cell measurement information needs to be reported. This application does not limit the method of indicating the identifiers of the one or more candidate cells. For example, the identifiers of the one or more candidate cells can be indicated by the physical cell identifier (PCI). Another example is that the identifiers of the one or more candidate cells can be indicated by the cell global identifier (CGI). Yet another example is that the identifiers of the one or more candidate cells can be indicated by the indexes of the candidate cells indicated by the network device in the candidate cell configuration, such as candidate cell 1, candidate cell 2, etc.

[0097] In some embodiments, the information of the antenna group of each candidate cell (i.e., the antenna group corresponding to each candidate cell, and the antenna group of the candidate cell mentioned below can be replaced with the antenna group corresponding to the candidate cell) can be used to determine which antenna groups the terminal device needs to measure and / or which antenna group measurement information needs to be reported.

[0098] In some embodiments, the antenna group information for each candidate cell may include the number of antenna groups in each candidate cell. This application does not limit the number of antenna groups in each candidate cell. Exemplarily, each candidate cell may have one or more antenna groups.

[0099] In some embodiments, the number of antenna groups in different candidate cells can be the same. For example, the number of antenna groups in candidate cell 1 and candidate cell 2 can both be K1.

[0100] In some embodiments, the number of antenna groups in different candidate cells can be different. For example, the number of antenna groups in candidate cell 1 can be K1, the number of antenna groups in candidate cell 2 can be K2, the number of antenna groups in candidate cell 3 can be K3, and the number of antenna groups in candidate cell 4 can be K4, wherein the values ​​of K1, K2, K3 and K4 can be different.

[0101] In some embodiments, the reference signal corresponding to the antenna group of each candidate cell may refer to the reference signal corresponding to one or more antenna groups (or some or all antenna groups) corresponding to each candidate cell. This application embodiment does not limit the reference signal corresponding to the antenna group of each candidate cell. Exemplarily, the reference signal corresponding to the antenna group of each candidate cell may include one or more of the following: SSB, CSI-RS, TRS, SRS, and demodulation reference signal (DMRS).

[0102] In some embodiments, the TCI state corresponding to the antenna group of each candidate cell can refer to the TCI state corresponding to one or more antenna groups (or some or all antenna groups) corresponding to each candidate cell. This application does not limit the TCI state corresponding to the antenna group of each candidate cell. For example, the TCI state corresponding to the antenna group of a candidate cell can be a unified TCI state. As another example, the TCI state corresponding to the antenna group of a candidate cell can include separate TCI states (such as downlink TCI state and / or uplink TCI state).

[0103] In some embodiments, the unified TCI state may include three modes: joint TCI state, downlink TCI state (DL TCI state), and uplink TCI state (UL TCI state). In some embodiments, the downlink TCI state and uplink TCI state included in the unified TCI state may be referred to as separate TCI states. For example, the downlink TCI state included in the unified TCI state may be referred to as a separate downlink TCI state (separate DL TCI state); and the uplink TCI state included in the unified TCI state may be referred to as a separate uplink TCI state (separate UL TCI state).

[0104] In some embodiments, the unified TCI state includes a joint TCI state applicable to both uplink and downlink channels and signals. In some embodiments, the unified TCI state includes a downlink TCI state applicable only to downlink channels and signals. In some embodiments, the unified TCI state includes an uplink TCI state applicable only to uplink channels and signals.

[0105] In some embodiments, downlink channels (e.g., partial PDCCH, PDSCH) and signals (e.g., aperiodic CSI-RS) may use the same downlink transmit beam, and the downlink channels and signals may be indicated using separate downlink TCI states or joint TCI states.

[0106] In some embodiments, the uplink channel (e.g., PUCCH, PUSCH) and signal (e.g., SRS) may use the same uplink transmit beam, and the uplink signal and signal may be indicated using separate uplink TCI states or joint TCI states.

[0107] It's important to clarify that the "unified" in "unified TCI state" has multiple layers of meaning. The first layer of "unified" means that the unified TCI state unifies the uplink and downlink beam indication mechanisms. In the Rel.15 / Rel.16 NR standards, the TCI state is only used for downlink beam indication; uplink beam indication uses signaling based on spatial relation information. The second layer of "unified" means beam unification between different channels. For example, in a separate downlink / uplink TCI state configuration, the terminal device can assume that the downlink PDCCH (UE-specific) and PDSCH (UE-specific) are transmitted using the same beam; similarly, the uplink PUCCH and PUSCH use the same beam. In a combined TCI state configuration, the terminal device can assume that different uplink and downlink channels and signals have good beam symmetry, meaning that symmetrical beam pairs are used for communication between uplink and downlink.

[0108] In some embodiments, the measurement information may be determined based on first indication information and / or second indication information. For example, the measurement information may be determined based on the first indication information. Or, for example, the measurement information may be determined based on the second indication information. The first and second indication information will be described below.

[0129] In some embodiments, the first candidate cell can be configured with a separate TCI state. For example, the first candidate cell can be configured with separate uplink TCI states and / or downlink TCI states.

[0130] In some embodiments, each antenna group in the antenna group of the first candidate cell can be configured with a uniform TCI state.

[0131] In some embodiments, each antenna group in the antenna group of the first candidate cell can be configured with a separate TCI state. For example, each antenna group can be configured with a separate uplink TCI state and / or downlink TCI state.

[0132] In some embodiments, the first indication information can be used to indicate one of the aforementioned information.

As an example, the first indication information can be used to indicate the identifier of the first candidate cell and the number of antenna groups in the first candidate cell. As another example, the first indication information can be used to indicate the identifier of the first candidate cell and the reference signal configuration of the first candidate cell.

Exemplarily, the first indication information may be carried in one or more of the following: RRC signaling, MAC CE, and DCI. For example, the first indication information may be carried in RRC signaling.

[0135] In some embodiments, the first indication information is configured at the granularity of candidate cells. That is, the network device can configure the first indication information once for each candidate cell. It should be noted that if the network device needs to configure the first indication information corresponding to multiple candidate cells to the terminal device, the network device can configure multiple sets of first indication information to the terminal device.

[0136] The second instruction information can be used to configure the terminal device to report measurement information. In this way, the terminal device can determine and / or report measurement information based on the first instruction information.

[0137] In some embodiments, the second indication information may be sent by the network device to the terminal device. Alternatively, the second indication information may be configured by the network device for the terminal device.

[0138] This application embodiment does not limit the second indication information. Exemplarily, the second indication information may be used to indicate one or more of the following: the number of reported candidate cells; the number of antenna groups reported by each candidate cell; the number of reference signals reported by each antenna group; and the number of TCI states reported by each antenna group.

[0149] In some embodiments, the second indication information may be carried in the first signaling. This application does not limit the first signaling. Exemplarily, the first signaling may include one or more of the following: RRC signaling, MAC CE, and DCI.

[0150] As an example, the first signaling may include RRC signaling.

[0151] In some embodiments, the first signaling and the signaling carrying the first indication information may be the same. For example, the first signaling and the signaling carrying the first indication information may be the same RRC signaling. Alternatively, the first signaling and the signaling carrying the first indication information may be the same MAC CE.

[0152] In some embodiments, the first signaling and the signaling carrying the first indication information may be different. For example, the first signaling and the signaling carrying the first indication information may be different RRC signaling. Another example is that the first signaling may be MAC CE, and the signaling carrying the first indication information may be RRC signaling.

[0153] In some embodiments, the first signaling may be related to mobility reporting configuration. For example, the first signaling may be related to LTM reporting configuration. Or, the first signaling may be signaling related to LTM reporting configuration. As an example, the first signaling may include LTM-ReportContent signaling.

[0154] Taking the first signaling as the LTM reporting content signaling as an example, the first signaling can indicate the following information: the number of candidate cells reported, the number of antenna groups reported by each candidate cell, and the number of reference signals reported by each antenna group. An example of LTM reporting content is as follows:

[0155] LTM-ReportContent-r18::=SEQUENCE{

[0156] nrOfReportedCells-r18 ENUMERATED{n1,n2,n3,n4},

[0157] nrOfReportedRS-PerAntennaPortGroup ENUMERATED{n1,n2,n3,n4},

[0158] spCellInclusion-r18 ENUMERATED{true}OPTIONAL--Need R

[0159] nrOfAntennaPortGroup{candidate values}

[0160] }

[0161] Among them, the parameter nrOfReportedCells indicates the number of candidate cells reported, the parameter nrOfReportedRS-PerAntennaPortGroup indicates the number of reference signals reported by each antenna group, and the parameter nrOfAntennaPortGroup indicates the number of antenna groups reported by each candidate cell.

[0162] Taking the first signaling as the LTM reporting content signaling as an example, the first signaling can indicate the following information: the number of candidate cells reported, the number of antenna groups reported by each candidate cell, and the number of TCI states reported by each antenna group. An example of LTM reporting content is as follows:

[0163] LTM-ReportContent-r18::=SEQUENCE{

[0164] nrOfReportedCells-r18 ENUMERATED{n1,n2,n3,n4},

[0165] nrOfTCIstates-PerAntennaPortGroup ENUMERATED{candidate value},

[0166] spCellInclusion-r18 ENUMERATED{true}OPTIONAL--Need R

[0167] nrOfAntennaPortGroup{candidate values}

[0168] }

[0169] Among them, the parameter nrOfReportedCells indicates the number of candidate cells reported, the parameter nrOfTCIstates-PerAntennaPortGroup indicates the number of TCI states reported by each antenna group, and the parameter nrOfAntennaPortGroup indicates the number of antenna groups reported by each candidate cell.

[0170] The measurement information has been introduced above; the measurement report will be introduced below.

[0171] This application does not limit the method of carrying the measurement report. In some embodiments, the measurement report may be carried in higher-layer signaling (such as RRC signaling). In some embodiments, the measurement report may be carried in MAC CE or DCI.

[0172] This application does not limit the information contained in the measurement report. For example, the measurement report may include one or more of the following information: identifiers (or indexes) of one or more candidate cells, identifiers of one or more antenna groups, identifiers of reference signals corresponding to one or more antenna groups, measurement information of reference signals corresponding to one or more antenna groups, identifiers (or indexes) of TCI states corresponding to one or more antenna groups, and measurement information of quasi-co-location reference signals associated with TCI states corresponding to one or more antenna groups.

[0173] The identifiers of the aforementioned one or more candidate cells can be used to distinguish which candidate cell(s) measurement information is being reported. This application embodiment does not limit the number of one or more candidate cells reported by the terminal device. This number can be configured by the network device through higher-layer signaling (such as RRC signaling), or it can be predefined or preconfigured, such as by protocol predefined parameters.

[0174] The identifiers of one or more antenna groups can be used to distinguish which antenna group(s) measurement information is being reported. These one or more antenna groups can be a subset of antenna groups associated with one or more candidate cells, or all antenna groups associated with one or more candidate cells.

[0175] The identifier of the reference signal corresponding to the aforementioned one or more antenna groups can also be understood as, or referred to as, a "reference signal resource indicator corresponding to one or more antenna groups." For example, the terminal device can indicate the identifier of the reference signal corresponding to each of the reported one or more antenna groups in the measurement report. As an example, suppose the terminal device needs to report measurement information for two candidate cells, where each candidate cell reports measurement information for two antenna groups, and each antenna group reports two reference signal resources. Then, the identifier of the reference signal corresponding to the one or more antenna groups can include eight identifiers (i.e., eight reference signal resource indicators need to be reported).

[0176] In some embodiments, the identifiers of the reference signals corresponding to one or more antenna groups are arranged in a preset order according to the identifiers of one or more reported candidate cells and the identifiers of one or more reported antenna groups. For example, the identifiers of the reference signals corresponding to one or more antenna groups are arranged in ascending order according to the identifiers of one or more reported candidate cells and the identifiers of one or more reported antenna groups. As another example, the identifiers of the reference signals corresponding to one or more antenna groups are arranged in descending order according to the identifiers of one or more reported candidate cells and the identifiers of one or more reported antenna groups. Taking the example that the identifiers of the reference signals corresponding to one or more antenna groups are arranged in ascending order according to the identifiers of one or more reported candidate cells and the identifiers of one or more reported antenna groups, assuming the terminal device needs to report measurement information for two candidate cells, where each candidate cell reports measurement information for two antenna groups, and each antenna group reports two reference signal resources, the terminal device needs to report the identifiers of eight reference signals, where the identifiers of these eight reference signals are the identifiers of the first to the eighth reference signals.

[0177] In some embodiments, if the identifiers of the reference signals corresponding to one or more antenna groups reported by the terminal device are arranged in a preset order according to the identifiers of one or more candidate cells and the identifiers of one or more antenna groups reported, the terminal device may not indicate the identifiers of the candidate cells and / or the identifiers of the antenna groups in the measurement report.

[0178] In some embodiments, the identifier of a reference signal corresponding to one or more antenna groups can be indicated by a first index, a second index, and a third index. The first index can be used to indicate the identifier of the candidate cell corresponding to the reference signal. The second index can be used to indicate the identifier of the antenna group corresponding to the reference signal. The third index can be used to indicate the identifier of the reference signal.

[0179] As an example, the identifier of the reference signal corresponding to one or more antenna groups can be obtained through D. i,j,k The indicator is given by i, where i represents the index of the candidate cell, j represents the index of the antenna group, and k represents the identifier of the reference signal (i.e., the kth reference signal resource).

[0180] In some embodiments, if the identifier of the reference signal corresponding to one or more antenna groups reported by the terminal device is indicated by a first index, a second index, and a third index, then the terminal device does not need to separately indicate the identifier of the candidate cell and / or the index of the antenna group in the measurement report.

[0181] The measurement information of the reference signals corresponding to one or more of the aforementioned antenna groups can be used to indicate the measurement information corresponding to each antenna group that needs to be reported in each candidate cell among the reported candidate cells. For a related introduction to the measurement information, please refer to the above text; it will not be repeated here.

[0182] This application embodiment does not limit the reference signal corresponding to one or more antenna groups. For example, the reference signal may include one or more of the following reference signals: SSB, CSI-RS, TRS, and SRS. Alternatively, this application embodiment does not limit the resources corresponding to the reference signal resource indication for one or more antenna groups, and the resources corresponding to the reference signal resource indication may include one or more of the following resources: SSB resources, CSI-RS resources, TRS resources, and SRS resources.

[0183] The identifiers of the TCI states corresponding to the aforementioned one or more antenna groups can also be understood as, or referred to as, "TCI state index indicators corresponding to one or more antenna groups." In some embodiments, the identifiers of the TCI states corresponding to one or more antenna groups reported by the terminal device can correspond to the identifiers of the TCI states of a certain antenna group in a candidate cell. For example, the terminal device can indicate the identifier of the TCI state corresponding to each of the reported one or more antenna groups in the measurement report. As an example, suppose the terminal device needs to report measurement information for two candidate cells, where each candidate cell reports measurement information for two antenna groups, and each antenna group reports two TCI states, then the identifiers of the reported one or more antenna groups corresponding to the TCI states can include eight identifiers (i.e., eight TCI state index indicators need to be reported).

[0184] In some embodiments, the identifiers of the TCI states corresponding to one or more antenna groups are arranged in a preset order according to the identifiers of the reported one or more candidate cells and the identifiers of the reported one or more antenna groups. For example, the identifiers of the TCI states corresponding to one or more antenna groups are arranged in ascending order according to the identifiers of the reported one or more candidate cells and the identifiers of the reported one or more antenna groups. As another example, the identifiers of the TCI states corresponding to one or more antenna groups are arranged in descending order according to the identifiers of the reported one or more candidate cells and the identifiers of the reported one or more antenna groups. Taking the example that the identifiers of the TCI states corresponding to one or more antenna groups are arranged in ascending order according to the identifiers of the reported one or more candidate cells and the identifiers of the reported one or more antenna groups, assuming the terminal device needs to report measurement information for two candidate cells, where each candidate cell reports measurement information for two antenna groups, and each antenna group reports two TCI states, the terminal device needs to report eight TCI state identifiers, which are the identifiers of the first to the eighth TCI states.

[0185] In some embodiments, if the identifiers of the TCI status corresponding to one or more antenna groups reported by the terminal device are arranged in a preset order according to the identifiers of one or more candidate cells and the identifiers of one or more antenna groups reported, the terminal device may not indicate the identifiers of the candidate cells and / or the identifiers of the antenna groups in the measurement report.

[0186] In some embodiments, the identifier of the TCI state corresponding to one or more antenna groups can be indicated by a first index, a second index, and a third index. The first index can be used to indicate the identifier of the candidate cell corresponding to the TCI state. The second index can be used to indicate the identifier of the antenna group corresponding to the TCI state. The third index can be used to indicate the identifier of the TCI state.

[0187] As an example, the TCI status identifier corresponding to one or more antenna groups can be obtained through D i,j,k The indicator is given by i, where i represents the index of the candidate cell, j represents the index of the antenna group, and k represents the identifier of the TCI state (i.e., the kth TCI state).

[0188] In some embodiments, if the identifier of the TCI status corresponding to one or more antenna groups reported by the terminal device is indicated by a first index, a second index, and a third index, then the terminal device does not need to separately indicate the identifier of the candidate cell and / or the index of the antenna group in the measurement report.

[0189] The measurement information of the quasi-co-location reference signal associated with the TCI state of one or more antenna groups can be used to indicate the measurement information corresponding to each antenna group that needs to be reported in each candidate cell.
