[0004] In related technologies, for idle and deactivated terminals, periodic Radio Resource Management (RRM) measurements are required for timely cell reselection. For connected terminals, measurements are performed based on network-configured settings. Although New Radio (NR) systems introduce RRM measurement relaxation for idle and deactivated terminals, and support RLM and Beam Failure Detection (BFD) measurement relaxation for connected terminals to reduce terminal measurements and power consumption, these relaxation mechanisms have limitations. Measurement relaxation only applies to some terminals within a cell, such as nearby or non-edge users; edge users still require measurements at shorter intervals.

[0083] To better understand the technical solution of this application, the following explains the channel knowledge map related to this application.

[0084] To achieve environmental awareness in wireless communication, the concept of channel knowledge maps has been proposed. In a broad sense, a channel knowledge map is a database with the physical or virtual location of mobile nodes as the main index. It can directly reflect the localized channel characteristics of a specific location, regardless of transceiver activity. Based on location and channel knowledge maps, it is helpful to obtain prior channel information in advance, improve the ability to understand the wireless environment, and realize rapid real-time prediction and reasoning of channel knowledge. It also helps to reduce or even eliminate complex real-time channel state and channel-related information acquisition.

[0085] Based on different environmental cognitive abilities, the following forms of channel knowledge maps can be generated:

[0086] Channel Gain Map (CGM) can predict the channel gain of wireless links in a target area. CGM can be used to adjust the transmitter's transmission status and other operations.

[0087] Channel Shadowing Map (CSM) is used to predict shadow fading in a target area or at a specific location.

[0088] Channel Path Map (CPM) parameters include the number of paths and their power, phase, delay, angle of arrival (AoA), and angle of departure (AoD).

[0089] In addition to the aforementioned quasi-static channel knowledge map, for relatively static environments or scenarios with periodically changing environments (such as smart factories), the channel knowledge map can also include relatively dynamic channel information, such as instantaneous channel state information (CSI) caused by multipath and Doppler frequency shift, and channel multipath information (path power, path delay), etc.

[0090] Compared to 3D city or terrain maps, radio environment maps, and blank television maps, channel knowledge maps delve deeper into the intrinsic characteristics of wireless channels. In principle, they rely solely on the radio propagation environment, without depending on additional parameters (such as the dielectric properties of the environment, transmitter status) or complex processing (such as ray tracing), thereby achieving environmental awareness and reducing or even avoiding real-time CSI acquisition.

[0091] To better understand the technical solution of this application, the following describes the perception-assisted communication related to this application.

[0092] Wireless communication and radar sensing have been developing in parallel, but with limited overlap. They share many commonalities in signal processing algorithms, equipment, and to some extent, system architecture. In recent years, traditional radar has been evolving towards more general wireless sensing. Wireless sensing broadly refers to retrieving information from received radio signals. Integrated Sensing and Communication (ISAC) has the potential to integrate wireless sensing into mobile networks. Sensing mobile networks can simultaneously provide communication and wireless sensing services, and due to their large broadband coverage and robust infrastructure, they hold the promise of becoming a ubiquitous wireless sensing solution.

[0093] In the application of sensing technology, sensing devices can perceive or understand the physical world through the transmission, reflection, and scattering of wireless signals in communication networks. Simultaneously, communication devices can leverage this sensing information to achieve high-precision positioning, imaging, and environmental reconstruction capabilities, thereby further improving communication performance, such as more accurate beamforming, faster beam fault recovery, and reduced CSI overhead. Technologies that utilize sensing to enhance communication performance can also be termed sensing-assisted communication.

[0094] In one illustration of sensing-assisted communication, the receiving end of the sensing device reconstructs the environment based on received sensing signals. These received sensing signals include direct signals and one or more signals reflected or scattered from the surrounding environment. Based on the reconstructed environmental signals, the location information of the signal transmitter and receiver, and a channel information prediction model, channel information is obtained. Channel modeling methods in the channel information prediction model include ray tracing and statistical methods.

[0095] To better understand the technical solution of this application, the following explains the terminal positioning related to this application.

[0096] Both channel knowledge maps and perception-assisted communication inevitably require obtaining the location information of the transmitting or receiving end during their application. Generally speaking, terminal location acquisition can be divided into two main categories: those based on the 3rd Generation Partnership Project (3GPP) and those not based on 3GPP.

[0097] Considering the increasing urgency of positioning needs from individual users and vertical industries, 3GPP has defined a series of positioning technologies for both 4G and 5G systems. In 4G systems, positioning accuracy reaches 10–100 meters primarily based on time-measured Observed Time Difference of Arrival (OTDOA), Uplink Time Difference of Arrival (UL-TDOA), and Cell Identity (CID), as well as schemes integrating multiple positioning technologies. Furthermore, for indoor scenarios, the protocol also supports positioning technologies based on Wireless LAN (WLAN) or Bluetooth. 5G systems further enhance positioning accuracy based on 4G systems. They not only propose to use the multi-beam characteristics of Multiple Input Multiple Output (MIMO) for positioning enhancement, but also define positioning technologies based on cellular round trip time (RTT), downlink time difference of arrival (DL-TDOA), angle of arrival (AOA), and angle of departure (AOD), so that the positioning accuracy can reach 3 to 10 meters.

[0098] Besides 3GPP-based positioning technologies, there are many other non-3GPP-based positioning methods, which can be achieved through the numerous sensors equipped on the terminal. These include GNSS-based positioning (such as GPS and BeiDou); laser-based or camera-based positioning, such as cameras or lidar on drones and vehicles; and inertial measurement units (IMUs) such as accelerometers and gyroscopes, which provide alternative methods for position estimation that relies little or no on external signals. These non-3GPP-based positioning technologies can serve as effective complementary means, improving positioning accuracy and supporting location acquisition in more scenarios.

[0099] To better understand the technical solution of this application, the following describes the RRM measurement, RLM measurement, and BFD measurement related to this application.

[0100] For idle and inactive terminals, the terminal needs to perform Receiving Retention Measurement (RRM) to achieve cell reselection and ensure terminal mobility. To reduce terminal power consumption, under certain conditions, the terminal is allowed to waive intra-frequency and / or equal and low-priority inter-frequency measurements. This mechanism mainly targets users in the cell center. Considering that when the terminal is not in the cell center or cell edge, the need for cell reselection is not urgent, the terminal can also appropriately relax RRM measurements to reduce terminal power consumption. Therefore, the NR system introduces an RRM measurement relaxation feature. Specifically, the network-side equipment configures a signal quality threshold as the trigger condition for RRM measurement relaxation. The terminal will only perform RRM measurement relaxation when the received signal quality meets certain requirements, such as exceeding the signal quality threshold configured by the network-side equipment, i.e., measuring with a longer period. In addition, for low-mobility users, a longer period can also be used for measurement. The terminal will judge based on the detection time and signal quality threshold configured by the network-side equipment. If the measurement results within a certain range over a period of time are considered low mobility, the relaxed period will be used for measurement.

[0101] For connected terminals, the terminal needs to perform radio link sensing and beam detection to determine whether the current radio link or beam signal quality meets the requirements. Similarly, considering that the signal quality of users in the cell center is generally better, when a user is in the cell center, the RLM measurement period or BFD measurement period of the connected terminal can be relaxed to reduce the terminal measurement. NR introduces RLM measurement relaxation features or BFD measurement relaxation features for connected users. Similar to the RLM measurement relaxation mechanism, the network-side equipment will configure a signal quality threshold for the terminal. Optionally, the network-side equipment will also configure a low-speed judgment time threshold for the terminal to determine whether the terminal is outside the cell edge or a low-speed user, and thus decide whether to perform measurement relaxation.

[0102] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0103] Figure 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application. As shown in Figure 2, the wireless communication method 200 may include at least some of the following:

[0104] S210, the terminal obtains first information; wherein, the first information includes at least one of the following: at least one set of channel knowledge maps, environmental information of at least one cell and location information of at least one cell or base station or TRP, second information associated with at least one region, and third information associated with the target scene;

[0105] S220, the terminal performs a first operation based on the first information; wherein the first operation includes at least one of the following: determining the RRM measurement period, determining the RLM measurement period, determining the BFD measurement period, determining the RRM measurement module, determining whether to send a first uplink signal related to auxiliary carrier adjustment, and determining whether to send a second uplink signal related to auxiliary station adjustment.

[0106] It should be understood that Figure 2 illustrates the steps or operations of the wireless communication method 200, but these steps or operations are merely examples, and other operations or variations of the various operations in Figure 2 may also be performed in this application.

[0107] It should be noted that RRM measurement relaxation is introduced for idle and deactivated terminals, while RLM or BFD measurement relaxation is supported for connected terminals. This reduces terminal measurements and lowers terminal power consumption. However, these methods still have limitations. Measurement relaxation is only applicable to some terminals within a cell, such as nearby or non-edge users. Furthermore, for terminals supporting carrier aggregation, after configuring a secondary carrier, measurements need to be performed on the secondary carrier regardless of its activation status, which also consumes terminal capacity and energy. Based on these technical issues, in this embodiment, the terminal performs a first operation based on first information. Compared to performing the first operation based on a measurement reference signal, this embodiment can be applied to all terminals in the cell without periodic reference signal detection, or can use a longer period for reference signal detection. This effectively reduces terminal measurements and increases the terminal's continuous sleep time, thereby reducing terminal power consumption.

[0108] In some embodiments, in S210 above, the terminal may receive the first information from a network-side device, or the terminal may obtain the first information locally.

[0109] Optionally, if the terminal obtains the first information locally, the first information is determined by the terminal based on historical data, or the first information is predicted by the terminal based on AI unit prediction.

[0110] Optionally, when the terminal can receive the first information from the network-side device, the first information may be carried by at least the following: system information (SI), radio resource control (RRC) signaling, downlink control information (DCI), and media access control control element (MAC CE) signaling.

[0111] The location information of at least one cell, base station, or TRP described in the embodiments of this application can be understood as the location information of at least one cell, or the location information of at least one base station, or the location information of at least one TRP.

[0112] In some embodiments, the first information is related to at least one of the following:

[0113] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0114] In some embodiments, the first information is related to channel knowledge information;

[0115] The channel knowledge information includes, but is not limited to, at least one of the following:

[0116] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0117] Optionally, the multipath information may include, but is not limited to, at least one of the following:

[0118] Path delay, path power, phase, angle.

[0119] In this embodiment of the application, the first information being related to the channel knowledge information can be understood as the channel knowledge information being obtained or predicted based on the first information.

[0120] It should be noted that the channel knowledge map is a database primarily indexed by the terminal's location (the terminal's geographic location and / or virtual location). It can directly reflect the localized channel characteristics of a specific location. It may also have other names, such as channel knowledge base, without specific limitations. Based on the terminal's location and the channel knowledge map, it helps to obtain prior channel information (i.e., channel quality information) in advance, improves the ability to understand the wireless environment, enables rapid real-time prediction and reasoning of channel knowledge, and helps to reduce or even eliminate complex real-time channel state and channel-related information acquisition.

[0121] Optionally, the geographic location of the terminal may include at least one of the following: physical location, 2D location range, 3D location range, angle and distance, and height information (relative height information or absolute height information).

[0122] Optionally, the virtual location of the terminal can be a measurement for the positioning of the terminal, wherein the measurement includes at least one of the following: time difference of arrival, round-trip time delay, departure angle, and arrival angle.

[0123] Optionally, the geographical location or virtual location of the terminal can also be a sub-region, a grid, or a radio frequency grid (e.g., the area is further divided into sub-regions, and each sub-region can be called a grid or a radio frequency grid).

[0124] In some embodiments, the channel knowledge map includes, but is not limited to, at least one of the following:

[0125] Channel Gain Map (CGM), Channel Shading Map (CSM), Channel Path Map (CPM), Line-of-Sight Link Probability Map, Dynamic Channel Knowledge Map.

[0126] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on a channel knowledge map.

[0127] Optionally, at least one of the following can be obtained or predicted based on the channel knowledge map:

[0128] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0129] For example, the channel knowledge map includes a channel gain map (CGM), which contains channel gain information for different geographical regions or geographical locations and their associated information. The channel gain map can predict the channel gain of wireless links in a target area and can be used to adjust the transmitter's transmission status. Specifically, channel gain can be directly obtained based on the channel gain map. Optionally, path loss, RSRP, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0130] For example, a channel knowledge map includes a channel shadow map (CSM), which contains different geographical regions or geographical locations and their associated shadow information (such as shadow variance, shadow fading, etc.). The channel shadow map (CSM) can be used to predict shadow fading in a target area or at a specific location. Specifically, shadow variance, shadow fading, etc., can be directly obtained based on the channel shadow map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0131] For example, a channel knowledge map includes a channel path map (CPM), which contains the number of paths associated with different geographical regions or geographical locations, the path power, phase, delay, and AoA, AoD, etc. Specifically, the number of paths, path power, phase, delay, and AoA, AoD, etc., can be directly obtained based on the channel path map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0132] For example, the channel knowledge map includes a line-of-sight (LOS) probability map, which contains multipath information for different geographical areas or locations, such as the distribution and probability of Line of Sight (LOS). Specifically, the number of paths, path power, phase, delay, and AoA and AoD can be directly obtained based on the LOS probability map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0133] Optionally, the angle information of the channel knowledge information can be the angle information of a few paths, such as the information of the N strongest paths. For example, for a terminal in a certain geographical location, the channel information obtained from the channel knowledge map includes: the path power, phase, vertical component of departure (zenith angle of departure, zenith AoD), and horizontal departure angle (azimuth angle of departure, azimuth AoD) of the three strongest paths.

[0134] It should be noted that the network-side device directly sends the channel knowledge map, and the terminal can directly obtain the corresponding channel knowledge information based on the location information.

[0135] It should be noted that the aforementioned channel knowledge map contains channel information for different geographical regions or geographical locations and their associated information. In other words, the terminal needs to query the channel knowledge map based on its location to obtain the corresponding channel knowledge information. The terminal location serves as an index to the channel knowledge map, either directly or indirectly.

[0136] For example, the input index of the Channel Knowledge Map (CKM) is terminal location information, which can be: a 2D location range, or a 3D location range, or location representation parameters based on polar coordinates such as angle and distance, or UE physical location information (such as latitude and longitude), or UE altitude information.

[0137] For example, the input index of the Channel Knowledge Map (CKM) is indirect information related to the UE's location. This indirect information corresponds to terminal measurements for different positioning methods, such as the time difference of reception of the positioning reference signal and the angle of arrival of the signal.

[0138] It is important to note that the channel knowledge map can be stored on the terminal side or the network side. In the scenario where it is stored on the terminal side, the terminal can obtain the corresponding channel information by querying the CKM based on its acquired terminal location information (such as downlink positioning-related measurements). In the scenario where it is stored on the network side, the network can obtain the channel information corresponding to the UE by querying the CKM based on its acquired terminal location information (such as location information reported by the terminal or obtained through uplink positioning-related measurements). Therefore, the different positioning methods mentioned above include relevant measurements used for both downlink and uplink positioning.

[0139] In some embodiments, the environmental information includes, but is not limited to, at least one of the following:

[0140] Radio map, sensing environmental point cloud information, 3D map.

[0141] In this embodiment, the environmental information can be point cloud information reconstructed from the physical world, such as the physical world of a digital twin; or the environmental information can be a radio environment map, such as a three-dimensional digital map, which represents information such as the height, width, length, and location of buildings; or the environmental information can be a 3D map, which can represent information such as the height, width, length, and location of objects in the environment; the environmental information can also include the electromagnetic reflection coefficients of objects, building surfaces, and point clouds.

[0142] It should be noted that the network-side device sends environmental information, and the terminal reconstructs the channel information or channel knowledge map based on ray tracing or other methods.

[0143] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on environmental information.

[0144] Optionally, at least one of the following can be obtained or predicted based on environmental information:

[0145] Path loss, channel gain, RSRP, multipath information, delay spread, CSI.

[0147] The service area includes one or more neighboring communities.

[0148] In some embodiments, the first information may include the identifier of the at least one region, or the first information may include the length and width information of the at least one region.

[0149] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on location information.

[0150] Optionally, at least one of the following can be obtained or predicted based on location information:

[0151] Path loss, channel gain, RSRP, AoA, AoD, multipath information, delay spread, CSI.

[0152] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on at least one region.

[0153] Optionally, at least one of the following can be obtained or predicted based on at least one region:

[0155] In some embodiments, the target scenario includes, but is not limited to, at least one of the following:

[0156] Underground parking garages, tunnels, elevators, high-speed trains, enclosed spaces, physical barriers.

[0157] For example, if the target scenario is a tunnel, and the terminal recognizes that it will enter the tunnel, it anticipates a sharp drop in signal quality. Therefore, the target scenario is related to channel knowledge information. In other words, the channel quality in the target scenario has some typical characteristics (such as a sharp drop and poor quality), and thus, channel knowledge information can be obtained using the target scenario.

[0158] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on the target scenario.

[0159] Optionally, at least one of the following can be obtained or predicted based on the target scenario:

[0160] Path loss, channel gain, RSRP, AoA, AoD, multipath information, delay spread, CSI.

[0161] In some embodiments, the RRM measurement module includes a master transceiver module or a low-power receiver module.

[0162] To reduce terminal power consumption, a low-power radio (LPR) module (or low radio, LR) is deployed in addition to the main transceiver module (MR). In NR systems, the low-power radio module only supports reception functions and is called a low-power wake-up receiver (LP-WUR). Because the low-power module has simpler components and relatively lower performance, its coverage area is significantly smaller than that of the main transceiver, as shown in Figure 3.

[0163] To further reduce terminal power consumption and allow the main transceiver module more sleep time, the NR system supports RRM measurement based on the low-power receiver module. Accordingly, the network-side equipment will configure a main transceiver signal quality threshold (e.g., to determine whether to enable the low-power receiver module to perform RRM measurement) and a low-power transceiver signal quality threshold (e.g., to determine whether to enable the main transceiver module to perform RRM measurement) to determine the module to perform the RRM measurement.

[0327] Figure 5 is a schematic flowchart of a wireless communication method 400 according to an embodiment of this application. As shown in Figure 5, the wireless communication method 400 may include at least some of the following:

[0328] S410, the network-side device receives fourth information; wherein, the fourth information includes at least one of the following: at least one set of channel knowledge maps, environmental information of at least one cell, and location information of at least one cell, base station, or TRP;

[0329] S420, the network-side device sends configuration information to the terminal according to the fourth information; wherein, the configuration information is used to reconfigure at least one of the following: RRM measurement period, RLM measurement period, BFD measurement period, secondary carrier change, and secondary station change.

[0330] It should be understood that Figure 5 illustrates the steps or operations of the wireless communication method 400, but these steps or operations are merely examples, and other operations or variations of the operations shown in Figure 5 may also be performed in this application.

[0331] In this embodiment, compared to reconfiguring the RRM measurement period, RLM measurement period, BFD measurement period, secondary carrier change, and secondary station change based on the measurement reference signal, the network-side device reconfigures the RRM measurement period, RLM measurement period, BFD measurement period, secondary carrier change, and secondary station change based on the fourth information. This can be applied to all terminals in the cell without periodic reference signal detection, or a longer period can be used for reference signal detection. This can effectively reduce terminal measurements and increase the continuous sleep time of the terminal, thereby reducing the terminal's power consumption.

[0332] The location information of at least one cell, base station, or TRP described in the embodiments of this application can be understood as the location information of at least one cell, or the location information of at least one base station, or the location information of at least one TRP.

[0333] In some embodiments, the fourth information is related to at least one of the following:

[0334] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0335] In some embodiments, the fourth information is related to channel knowledge information;

[0337] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0338] Optionally, the multipath information may include, but is not limited to, at least one of the following:

[0339] Path delay, path power, phase, angle.

[0340] In this embodiment of the application, the fourth information being related to the channel knowledge information can be understood as the channel knowledge information being obtained or predicted based on the fourth information.

[0341] It should be noted that the channel knowledge map is a database primarily indexed by the terminal's location (the terminal's geographic location and / or virtual location). It can directly reflect the localized channel characteristics of a specific location. It may also have other names, such as channel knowledge base, without specific limitations. Based on the terminal's location and the channel knowledge map, it helps to obtain prior channel information (i.e., channel quality information) in advance, improves the ability to understand the wireless environment, enables rapid real-time prediction and reasoning of channel knowledge, and helps to reduce or even eliminate complex real-time channel state and channel-related information acquisition.

[0342] Optionally, the geographic location of the terminal may include at least one of the following: physical location, 2D location range, 3D location range, angle and distance, and height information (relative height information or absolute height information).

[0343] Optionally, the virtual location of the terminal can be a measurement for the positioning of the terminal, wherein the measurement includes at least one of the following: time difference of arrival, round-trip time delay, departure angle, and arrival angle.

[0344] Optionally, the geographical location or virtual location of the terminal can also be a sub-region, a grid, or a radio frequency grid (e.g., the area is further divided into sub-regions, and each sub-region can be called a grid or a radio frequency grid).

[0345] In some embodiments, the channel knowledge map includes, but is not limited to, at least one of the following:

[0346] Channel Gain Map (CGM), Channel Shading Map (CSM), Channel Path Map (CPM), Line-of-Sight Link Probability Map, Dynamic Channel Knowledge Map.

[0347] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on a channel knowledge map.

[0348] Optionally, at least one of the following can be obtained or predicted based on the channel knowledge map:

[0349] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0350] For example, the channel knowledge map includes a channel gain map (CGM), which contains channel gain information for different geographical regions or geographical locations and their associated information. The channel gain map can predict the channel gain of wireless links in a target area and can be used to adjust the transmitter's transmission status. Specifically, channel gain can be directly obtained based on the channel gain map. Optionally, path loss, RSRP, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0351] For example, a channel knowledge map includes a channel shadow map (CSM), which contains different geographical regions or geographical locations and their associated shadow information (such as shadow variance, shadow fading, etc.). The channel shadow map (CSM) can be used to predict shadow fading in a target area or at a specific location. Specifically, shadow variance, shadow fading, etc., can be directly obtained based on the channel shadow map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0352] For example, a channel knowledge map includes a channel path map (CPM), which contains the number of paths associated with different geographical regions or geographical locations, the path power, phase, delay, and AoA, AoD, etc. Specifically, the number of paths, path power, phase, delay, and AoA, AoD, etc., can be directly obtained based on the channel path map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0353] For example, the channel knowledge map includes a line-of-sight (LOS) probability map, which contains multipath information for different geographical areas or locations, such as the distribution and probability of Line of Sight (LOS). Specifically, the number of paths, path power, phase, delay, and AoA and AoD can be directly obtained based on the LOS probability map. Optionally, path loss, channel gain, RSRP, spatial correlation matrix, multipath information, Rice factor, angle spread, delay spread, CSI, etc., can be further obtained.

[0354] Optionally, the angle information of the channel knowledge information can be the angle information of a few paths, such as the information of the N strongest paths. For example, for a terminal in a certain geographical location, the channel information obtained from the channel knowledge map includes: the path power, phase, vertical component of departure (zenith angle of departure, zenith AoD), and horizontal departure angle (azimuth angle of departure, azimuth AoD) of the three strongest paths.

[0355] It should be noted that the network-side device directly sends the channel knowledge map, and the terminal can directly obtain the corresponding channel knowledge information based on the location information.

[0356] It should be noted that the aforementioned channel knowledge map contains channel information for different geographical regions or geographical locations and their associated information. In other words, the terminal needs to query the channel knowledge map based on its location to obtain the corresponding channel knowledge information. The terminal location serves as an index to the channel knowledge map, either directly or indirectly.

[0357] For example, the input index of the Channel Knowledge Map (CKM) is terminal location information, which can be: a 2D location range, or a 3D location range, or location representation parameters based on polar coordinates such as angle and distance, or UE physical location information (such as latitude and longitude), or UE altitude information.

[0358] For example, the input index of the Channel Knowledge Map (CKM) is indirect information related to the UE's location. This indirect information corresponds to terminal measurements for different positioning methods, such as the time difference of reception of the positioning reference signal and the angle of arrival of the signal.

[0359] It is important to note that the channel knowledge map can be stored on the terminal side or the network side. In the scenario where it is stored on the terminal side, the terminal can obtain the corresponding channel information by querying the CKM based on its acquired terminal location information (such as downlink positioning-related measurements). In the scenario where it is stored on the network side, the network can obtain the channel information corresponding to the UE by querying the CKM based on its acquired terminal location information (such as location information reported by the terminal or obtained through uplink positioning-related measurements). Therefore, the different positioning methods mentioned above include relevant measurements used for both downlink and uplink positioning.

[0360] In some embodiments, the environmental information includes, but is not limited to, at least one of the following:

[0361] Radio map, sensing environmental point cloud information, 3D map.

[0362] In this embodiment, the environmental information can be point cloud information reconstructed from the physical world, such as the physical world of a digital twin; or the environmental information can be a radio environment map, such as a three-dimensional digital map, which represents information such as the height, width, length, and location of buildings; or the environmental information can be a 3D map, which can represent information such as the height, width, length, and location of objects in the environment; the environmental information can also include the electromagnetic reflection coefficients of objects, building surfaces, and point clouds.

[0363] It should be noted that the network-side device sends environmental information, and the terminal reconstructs the channel information or channel knowledge map based on ray tracing or other methods.

[0364] In some implementations, the aforementioned channel knowledge information can be obtained or predicted based on environmental information.

[0381] In some embodiments, different sets of channel knowledge maps in the at least one set of channel knowledge maps are associated with different frequency domain ranges (e.g., 700MHz to 800MHz), meaning that channel knowledge maps can be configured according to frequency domain range granularity (per frequency domain range).

[0409] It should be noted that the network side directly sends the channel knowledge map, and the terminal can directly obtain the corresponding channel knowledge based on the location information.

[0410] 2) Environmental information of at least one residential area

[0420] Underground parking garages, tunnels, elevators, high-speed trains, enclosed spaces, physical barriers.

[0421] In one possible implementation, the first information includes one or more RRM measurement cycles, or coefficients for determining the RRM measurement cycle (e.g., determining the RRM measurement cycle based on the product of a default cycle and the measurement cycle coefficient); each RRM measurement cycle / measurement cycle coefficient is associated with one or more target scenarios, which can be identified through measurement signals, sensing, sensor devices, etc.

[0422] 5) Location information of at least one cell, base station, or TRP

[0424] Optionally, the location information of the serving cell can be replaced with the location information of the base station, and the location information of the neighboring cell can be replaced with the location information of the neighboring station.

[0425] 6) RRM measurement cycle determination conditions

[0426] In one possible implementation, the network side configures a signal quality threshold to determine the RRM measurement period or RRM measurement period coefficient. In another possible implementation, the network side configures a region-based RRM measurement period or RRM measurement period coefficient.

[0427] 7) RRM measurement signal configuration

[0428] The RRM measurement signal configuration information includes one or more of the following: measurement reference signal transmission power, measurement reference signal transmission period.

[0429] It should be noted that the aforementioned channel knowledge map contains channel information for different geographical regions or geographical locations and their associated information. In other words, the terminal needs to query the channel knowledge map based on its location to obtain the corresponding channel knowledge information. The terminal location serves as an index to the channel knowledge map, either directly or indirectly.

[0430] Optionally, the input index of the Channel Knowledge Map (CKM) is UE location-related information, which can be: 2D location range, or 3D location range, or location representation parameters based on polar coordinates such as angle and distance, or UE physical location information (such as latitude and longitude), or UE altitude information.

[0431] Optionally, the input index of the Channel Knowledge Map (CKM) is indirect information related to the UE's location, where the indirect information corresponds to terminal measurements for different positioning methods, such as the time difference of reception of the positioning reference signal and the angle of arrival of the signal.

[0432] Specifically, this includes positioning measurements corresponding to various positioning methods, such as:

[0433] Downlink (DL) positioning reference signals (PRS) received power (DL PRS-RSRP);

[0434] Downlink relative signal time difference (DL RSTD);

[0435] UE Rx–Tx time difference;

[0436] Uplink relative arrival time (UL Relative Time of Arrival, TUL-RTOA);

[0437] Base station-side receive-transmit time difference (gNB Rx–Tx time difference);

[0438] UL Angle of Arrival (UL AoA);

[0439] Uplink (UL) Sounding Reference Signal (SRS) Received Power (UL SRS-RSRP);

[0440] Downlink PRS reference signal received path power (DL PRS-RSRPP);

[0441] Uplink SRS reference signal received path power (UL SRS reference signal received path power, UL SRS-RSRPP);

[0442] Downlink reference signal carrier phase (DL RSCP);

[0443] Downlink reference signal carrier phase difference (DL RSCPD);

[0444] Uplink reference signal carrier phase (UL RSCP).

[0445] It is important to note that the Channel Knowledge Map (CKM) can be stored on the terminal side or the network side. In scenarios where the CKM is stored on the terminal side, the terminal can retrieve the corresponding channel information by querying the CKM based on its acquired terminal location information (such as downlink positioning-related measurements). In scenarios where the CKM is stored on the network side, the network can retrieve the UE's corresponding channel information by querying the CKM based on its acquired terminal location information (such as location information reported by the terminal or obtained through uplink positioning-related measurements). Therefore, the different positioning methods mentioned above include relevant measurements used for both downlink and uplink positioning.

[0446] Optionally, in addition to geographic location information, the aforementioned location information may also include the UE's orientation or attitude, for example, obtained by the terminal through an inertial measurement unit, or through accelerometers and gyroscopes on the terminal side.

[0447] Optionally, in addition to geographic location information, the aforementioned location information may also include terminal movement information, including terminal movement speed and terminal movement direction. Optionally, by combining with artificial intelligence (AI), terminal movement information can also be used to predict the future location of the terminal.

[0448] S1-2. The terminal obtains its location information.

[0449] The location of the terminal can be obtained using 3GPP-based technology or non-3GPP-based technology; no specific limitation is made in this embodiment.

[0450] The terminal's location information can be obtained based on one or more of the following methods in combination: network-assisted GNSS methods; LTE signal-based Time Difference of Arrival (OTDOA) positioning; LTE signal-based Enhanced Cell Identification (ID) method; WLAN positioning; Bluetooth positioning; Terrestrial Beacon System (TBS) positioning; sensor-based methods (barometric sensor, motion sensor); NR signal-based Enhanced Cell ID (E-CID); NR signal-based Multi-Round-Trip (Multi-RTT) positioning; NR signal-based Downlink Departure Angle (DL-AoD); NR signal-based Downlink Time Difference of Arrival (DL-TDOA); NR signal-based Uplink Time Difference of Arrival (UL-TDOA); NR signal-based Uplink Angle of Arrival (UL-AoA); Sidelink (SL) positioning and ranging based on sidelink signals (Sidelink Round-Trip (SL-RTT); Sidelink Angle of Arrival); Ultra Wideband (UWB) positioning... Positioning methods include: band (UWB) positioning; radar-based positioning; sensing signal-based positioning; laser-based positioning; and positioning based on accelerometers and gyroscopes or barometers (for measuring altitude).

[0451] Whether a terminal acquires location information depends on its implementation. In one possible implementation, the terminal supports cell handover based on channel knowledge information, and upon receiving the first information sent by the network side, the terminal can acquire its location information in the aforementioned manner. In another possible implementation, the acquisition of the terminal's location information does not depend on the acquisition of the aforementioned first information. For example, in a drone scenario, the terminal always uses GPS to acquire its real-time location. In this scenario, the acquisition of location information is not triggered by receiving the first information.

[0452] S1-3. Determine the RRM measurement cycle based on terminal location information and first information.

[0453] The terminal determines the RRM measurement cycle based on the first information received and the terminal location information.

[0454] In some implementations, the first information provided by the network side includes at least one set of channel knowledge information. Specifically, the terminal determines the RRM measurement period based on at least one set of channel knowledge information and the terminal location information.

[0455] For example, the first information provided by the network may include channel knowledge information or a channel knowledge map. For instance, the first information provided by the network may include a channel gain map. Based on the acquired terminal location and the channel knowledge map, the terminal obtains channel information for its current location, such as the channel gain at the current location, or the path loss value and shadowing fading information for the current location. Based on the transmit power of the RRM measurement signal provided by the network and the channel information obtained by the terminal based on the channel knowledge map, the terminal evaluates the signal quality and selects the corresponding / associated RRM measurement period. Optionally, the terminal location acquired by the terminal may also include terminal movement information (including movement speed, movement direction, etc.). Based on the channel knowledge map and the terminal movement information, the terminal can also predict its future location and obtain channel information for that future location.

[0456] For example, the signal quality at a given location is calculated based on the transmit power of the RRM measurement signal and the acquired channel information. This signal quality is then compared with a signal quality threshold configured on the network side to determine the RRM measurement period. If the signal quality is below the threshold, a relatively short period is used for RRM measurement (e.g., the default RRM measurement period is used). If the signal quality is above the threshold, a relatively long period is used for RRM measurement (e.g., the default RRM measurement period * 4 is used).

[0457] Optionally, the network side can configure one or more thresholds corresponding to different RRM measurement periods.

[0458] In some implementations, the first information provided by the network side includes environmental information of at least one cell. Specifically, the terminal determines the RRM measurement cycle based on the environmental information of at least one cell and the terminal's location information.

[0459] The first information provided by the network includes point cloud information containing environmental information, such as point cloud data containing environmental maps, or containing radio environment map information, or 3D map information.

[0460] Optionally, the first information may also include the location information of the serving cell or the location information of the base station. Based on the terminal location obtained in S1-2 above, combined with the location information of the serving cell or the location information of the base station and the radio environment map information, the terminal performs channel modeling to obtain the channel information between the serving cell and the UE. For example, the channel modeling may be based on the ray tracing method.

[0461] The terminal evaluates the signal quality based on the transmit power of the RRM measurement signal provided by the network side and the channel information obtained from the reconstruction of the radio environment map, and selects the corresponding / associated RRM measurement period.

[0462] In some implementations, the first information provided by the network side includes at least one region-associated RRM measurement cycle information. Specifically, the terminal determines the RRM measurement cycle based on at least one region-associated RRM measurement cycle information and the terminal's location information.

[0463] The first information provided by the network side includes at least one RRM measurement cycle associated with a region (the signaling form may be: each RRM measurement cycle is associated with a set of zone IDs). The terminal determines the zone ID it belongs to based on its current location, selects the RRM measurement cycle associated with that zone ID, and performs the RRM measurement.

[0464] In some implementations, the first information provided by the network side includes the association information between the target scene and the RRM measurement cycle. Specifically, the terminal determines the RRM measurement cycle based on the association information between the target scene and the RRM measurement cycle, as well as the terminal's location information.

[0465] The first information provided by the network side includes the correlation between the target scene and the RRM measurement cycle. The terminal can identify the target scene based on perception, tags, measurement, AI unit prediction, etc., and determine the RRM measurement cycle according to the correlation between the received target scene and the RRM measurement cycle.

[0466] For example, the target scene could be a tunnel scene, an object occlusion scene, etc. After the terminal identifies the target scene, it uses the RRM measurement cycle associated with the target scene to perform the measurement.

[0467] Optionally, the target scene can be identified / distinguished by changes in the signal, such as a sharp drop in signal quality.

[0468] Optionally, the above implementation methods can be used in combination. For example, the terminal can determine the RRM measurement cycle based on its current geographical region and the detected target scene.

[0469] As described above, for terminals that support RRM measurement assisted by channel knowledge information, the terminal can determine the RRM measurement period based on the channel knowledge information. To perform cell reselection, the terminal needs to perform RRM measurement, and this can be further divided into whether or not channel knowledge information is used. For scenarios / terminals that do not use channel knowledge information, the RRM measurement period is the same as in existing technologies; for scenarios / terminals that support channel knowledge information, the terminal can use a longer period for RRM measurement, and in certain specific scenarios, it can even rely solely on the evaluation results of channel knowledge information.

[0470] For terminals that support RRM measurement based on channel information, one possible implementation is that the terminal obtains signal quality based on channel knowledge information and combines it with reference signal measurement to jointly perform RRM measurement or jointly perform cell reselection judgment. In this way, by using channel knowledge information, the measurement of reference signal is reduced, which helps to reduce terminal power consumption. At the same time, it does not rely entirely on channel knowledge information. The terminal needs to perform RRM measurement over a relatively long period of time, which improves the reliability of the measurement results.

[0471] Optionally, for terminals that support channel-information-assisted RRM measurements, the terminal can improve the reliability of the results by combining the estimation results based on channel knowledge information with long-period signal measurement results. For example, the terminal can perform L3 filtering in conjunction with the channel knowledge information estimation results and signal measurement results.

[0472] Since there may be terminals in the network that support RRM measurement based on channel information assisted by this embodiment as well as terminals that do not support this measurement method, the network side provides two sets of configurations (config1, config2) to support terminals that support RRM measurement based on channel information assisted by channel information (config1) and terminals that do not support RRM measurement based on channel information assisted by channel information (config2), respectively. Under the same channel quality conditions, the RRM measurement period associated / configured / included in config1 is longer than the RRM measurement period associated / configured / included in config2.

[0473] It should be noted that for terminals in an idle state or an inactive state, the RRM measurement of the terminal includes intra-frequency measurement and possible inter-frequency measurement. The RRM measurement based on information knowledge described in this embodiment can be applied to intra-frequency measurement and inter-frequency measurement (including high-priority inter-frequency, same-priority inter-frequency, and low-priority inter-frequency measurement), or the RRM measurement based on channel knowledge can be used only for intra-frequency measurement and same / low-priority inter-frequency measurement.

[0474] In this embodiment, the terminal uses channel knowledge information sent from the network or reconstructed by the terminal, combined with the terminal's location, to obtain channel signal quality, thereby determining the RRM measurement cycle or performing RRM measurements. By utilizing the auxiliary information provided by channel knowledge, RRM measurements are reduced, or even eliminated, increasing the terminal's sleep time and helping to further reduce terminal power consumption.

[0475] Example 2, using RLM measurement (relaxation) or BFD measurement (relaxation) as an example.

[0476] In this embodiment, the network-side device provides the terminal with first information (such as channel knowledge information). This first information can be used for RLM measurement (relaxation) or BFD measurement (relaxation). The terminal performs RLM measurement (relaxation) or BFD measurement (relaxation) based on the first information provided by the network-side device. Specifically, the terminal uses the channel knowledge information sent by the network or reconstructed by the terminal, combined with the terminal's location, to obtain the channel signal quality, and then determines the RRM measurement period or performs RRM measurement. By using the auxiliary information provided by the channel knowledge information, RRM measurement is reduced, or even eliminated, increasing the terminal's sleep time and helping to further reduce terminal power consumption.

[0477] Optionally, the first information is related to at least one of the following:

[0478] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0479] As shown in Figure 7, Embodiment 2 may specifically include some or all of S2-1 to S2-3.

[0480] The overall scheme of this embodiment is the same as that of Embodiment 1 above. The difference is that Embodiment 1 is for RRC idle terminals or RRC inactive terminals for RRM measurement, while this embodiment is for RRC connected terminals for RLM measurement or BFD measurement. On the other hand, since Embodiment 1 is for RRC idle terminals or RRC inactive terminals, the first information related to RRM measurement is broadcast through system messages, while the first information related to RLM or BFD measurement for RRC connected terminals in this embodiment is configured through RRC signaling (that is, the network side configures different signaling for different protocols).

[0481] Similar to Embodiment 1 above, the network side needs to provide the terminal with first information related to RLM / BFD measurement. The terminal determines the RLM / BFD measurement cycle based on the acquired terminal location and the received first information. Specifically, the solution can be as described in Embodiment 1 above, which will not be repeated here.

[0482] Optionally, the terminal side can obtain a channel knowledge map or environmental information (such as an RF map), and combine it with the terminal location to obtain the channel signal quality, thereby determining the RLM or BFD measurement period or performing RLM or BFD measurements.

[0483] Optionally, the network side (base station) obtains channel knowledge map or environmental information, and uses the terminal location information obtained by the network side to configure RLM or BFD measurement period for the terminal.

[0484] The channel knowledge map or environmental information obtained by the network side is generated by the base station or sent to the base station by other base stations or the core network.

[0485] Optionally, the base station determines the terminal's RLM or BFD measurement period based on the channel knowledge map or environmental information of multiple base stations or multiple TRPs, as well as the terminal's location (physical or virtual location), and notifies the terminal of the measurement period, such as by configuring the RLM or BFD measurement period through RRC signaling.

[0486] The terminal location can be obtained in at least one of the following ways:

[0487] The terminal reports location information or location area; wherein, the terminal location information or location area can be obtained by the terminal based on GNSS, or it can be obtained based on the downlink positioning method defined by 3GPP, such as DL PRS reference signal received power (DL PRS-RSRP), DL relative signal time difference (DL RSTD), UE Rx–Tx time difference, etc. as described in Example 1.

[0488] The network side obtains the terminal location; wherein, the network obtains the terminal location based on the uplink positioning method defined by 3GPP, such as gNB Rx–Tx time difference, UL Angle of Arrival (UL AoA), UL SRS reference signal received power (UL SRS-RSRP), etc. as described in Example 1.

[0489] The solution in this embodiment allows the terminal to obtain channel signal quality by using channel knowledge information sent by the network or reconstructed by the terminal, combined with the terminal's location, and then determine the RLM / BFD measurement period or perform RLM / BFD measurements. This reduces the need for RLM / BFD measurements and helps to reduce terminal power consumption.

[0490] Example 3 uses RLM measurement (relaxation) or BFD measurement (relaxation) as examples.

[0491] In this embodiment, the network-side device provides the terminal with first information (such as channel knowledge information), wherein the first information can be used to determine the RRM measurement module, and the terminal determines the RRM measurement module based on the first information provided by the network-side device. Specifically, the network side provides channel knowledge-related information, optionally, and conditions related to determining the RRM measurement cycle; the terminal determines the module performing the RRM measurement based on the first information (such as channel knowledge information) provided by the network side and the terminal location information.

[0492] Optionally, the first information is related to at least one of the following:

[0493] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0494] To reduce terminal power consumption, a low-power receiver module is deployed in addition to the main transceiver module. In NR systems, the low-power receiver module only supports reception functions and is called LP-WUR. Because the low-power receiver module is simpler and its performance is relatively worse, its coverage area is significantly smaller than that of the main transceiver module.

[0495] To further reduce terminal power consumption and allow the main transceiver module more sleep time, the NR system supports RRM measurement based on the low-power receiver module. Accordingly, the network side will configure a main transceiver signal quality threshold (e.g., to determine whether to enable the low-power module to perform RRM measurement) and a low-power receiver signal quality threshold (e.g., to determine whether to enable the main transceiver to perform RRM measurement) to determine the module to perform the RRM measurement.

[0496] As shown in Figure 8, Embodiment 3 may specifically include some or all of S3-1 to S3-3.

[0497] S3-1. The network-side device sends first information to the terminal, wherein the first information is related to the decision of the RRM measurement module.

[0498] Optionally, the network-side device may broadcast the first information via system messages.

[0499] Optionally, the first information includes at least one of the following:

[0500] 1) At least one channel knowledge map

[0501] Optionally, different sets of channel knowledge maps in at least a portion of the at least one set of channel knowledge maps are associated with different frequency points or frequency domain ranges; and / or, different sets of channel knowledge maps in at least a portion of the at least one set of channel knowledge maps are associated with different base stations or TRPs or cells or regions or grids or radio frequency grids.

[0502] Optionally, the at least partial channel knowledge map satisfies at least one of the following:

[0503] Each set of channel knowledge maps in the at least partial channel knowledge maps contains channel information for at least two locations within the associated frequency points or frequency domain range;

[0504] Each set of channel knowledge maps in the at least partial channel knowledge map contains channel information for at least two locations within an associated base station, TRP, cell, or area; or each set of channel knowledge maps in the at least partial channel knowledge map contains channel information for an associated grid or radio frequency grid; or each set of channel knowledge maps in the at least partial channel knowledge map contains channel information for an associated area or at least two sub-areas within an area.

[0505] Optionally, the channel knowledge map includes, but is not limited to, at least one of the following:

[0506] Channel Gain Map (CGM), Channel Shading Map (CSM), Channel Path Map (CPM), Line-of-Sight Link Probability Map, Dynamic Channel Knowledge Map.

[0507] The channel knowledge map includes channel information for different geographical regions or geographical locations and their associated information. The channel information may include one or more of the following: path loss, channel gain, signal reception quality (RSRP), shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information (path delay, path power, phase, angle, etc.), Rice factor, angle spread, and delay spread. Optionally, the channel information may also include CSI information, such as a periodic CSI change model. For example, in a smart factory scenario, the environment is relatively fixed, the driving path is relatively fixed, and the CSI change is also relatively fixed.

[0508] For example, the channel knowledge map includes a channel gain map, which contains channel gain information for different geographical regions or geographical locations and their associated channel gain information.

[0509] For another example, the channel knowledge map includes a line-of-sight link probability map, which contains the distribution and probability of LOS in different geographical areas, or the distribution and probability of LOS in different geographical locations.

[0512] It should be noted that the network side directly sends the channel knowledge map, and the terminal can directly obtain the corresponding channel knowledge based on the location information.

[0517] The environmental information may include perceived environmental point cloud information, such as point cloud information reconstructed from the physical world, such as the physical world of a digital twin; or the environmental information may include radio maps, such as three-dimensional digital maps, representing information such as the height, width, length, and location of buildings in this way; or the environmental information may include 3D maps, which can represent information such as the height, width, length, and location of objects in the environment; the environmental information may also include the electromagnetic reflection coefficients of objects, building surfaces, point clouds, etc.

[0518] It should be noted that after obtaining the environmental information of the at least one cell, the terminal reconstructs the channel information of the at least one cell based on the environmental information of the at least one cell, combined with ray tracing or other methods, or reconstructs the channel knowledge map of the at least one cell.

[0519] 3) RRM measurement module associated with at least one region

[0520] In one possible implementation, the first information includes the association between the RRM measurement module and the region; for example, one or more regions or zone IDs associated with the main transceiver and one or more regions or zone IDs associated with the low-power module are configured respectively; the terminal can determine the corresponding geographical region based on the region identifier (zone ID), and the zone ID can be obtained based on the region size configured on the network side and the protocol predefined calculation method.

[0524] 5) RRM measurement module judgment conditions

[0525] Optionally, a signal quality threshold can be configured on the network side to determine the RRM measurement module.

[0526] Optionally, the network side is configured with two sets of signal quality thresholds, one for the main transceiver module and the other for the low-power module.

[0527] 6) Network reference transmit power

[0528] Specifically, it can be the network reference transmit power used for RRM measurements.

[0529] S3-2. The terminal obtains location information.

[0530] Similar to Embodiment 1 above, the location acquisition of the terminal can be based on 3GPP technology or non-3GPP technology; no specific limitation is made in this embodiment.

[0531] S3-3. Determine the RRM measurement module based on terminal location information and first information.

[0532] The terminal determines the RRM measurement module based on the first information received and the terminal location information.

[0533] In some implementations, the first information provided by the network side includes at least one set of channel knowledge maps. Specifically, the terminal determines the RRM measurement module based on at least one set of channel knowledge maps and the terminal's location information.

[0534] Optionally, the first information provided by the network side includes channel knowledge information or a channel knowledge map. Based on the acquired terminal location and the channel knowledge map, the terminal obtains the channel information of its current location, evaluates the signal quality by combining the network reference transmit power provided by the network side for RRM measurement, and determines the RRM measurement module by determining the threshold according to the measurement module configured by the network side.

[0535] In some implementations, the first information provided by the network side includes environmental information of at least one cell. Specifically, the terminal determines the RRM measurement module based on the environmental information of at least one cell and the terminal's location information.

[0536] The first information provided by the network includes point cloud information containing environmental information, such as point cloud data containing an environmental map, or point cloud data containing radio environment map information, as well as the location information of the serving cell or base station. Based on the terminal location obtained in step 2 above, combined with the location information of the serving cell or base station and the radio environment map information, the terminal performs channel modeling to obtain the channel information between the serving cell and the UE. Based on the transmit power of the RRM measurement signal provided by the network side and the channel information obtained from the radio environment map reconstruction, the terminal evaluates the signal quality and determines the RRM measurement module according to the threshold determined by the measurement module configured by the network side.

[0537] In some implementations, the first information provided by the network side includes RRM measurement module information associated with at least one region. Specifically, the terminal determines the RRM measurement module based on the RRM measurement module information associated with at least one region and the terminal's location information.

[0538] The first information provided by the network side includes one or more RRM measurement module information associated with a geographical area (the signaling form may be: each RRM measurement module is associated with a set of area identifiers / zone IDs). The terminal determines the area identifier it belongs to based on its current location and selects the RRM measurement module associated with that area identifier.

[0539] In some implementations, the first information provided by the network side includes the association information between the target scene and the RRM measurement module. Specifically, the terminal determines the RRM measurement module based on the association information between the target scene and the RRM measurement module, as well as the terminal's location information.

[0540] The first information provided by the network side includes the association between the target scene and the RRM measurement module. The terminal can identify the target scene based on perception, tags, measurement, AI unit prediction, etc., and select the corresponding RRM measurement module according to the determined target scene.

[0541] The threshold determined by the RRM measurement module configured on the network side can be based on the main transceiver module, the low-power receiver module, or both. In this case, the terminal can jointly determine the measurement module based on the measurement results of the corresponding module and the channel quality estimated based on channel knowledge information.

[0542] Alternatively, no distinction can be made, that is, the network side only configures a threshold, the terminal obtains the channel information based on the above method, evaluates the signal quality, and compares it with the threshold, and then determines the RRM measurement module. For example, if it is higher than the threshold, the low power receiver module is used to perform RRM measurement, and if it is lower than the threshold, the main transceiver module is used to perform RRM measurement.

[0543] The solution in this embodiment allows the terminal to use channel knowledge information sent from the network or reconstructed by the terminal, combined with the terminal location to obtain channel signal quality, and determine the RRM measurement module. This reduces related measurements and helps to reduce terminal power consumption. For scenarios where the RRM measurement signal period is long, this method helps to switch the RRM measurement module earlier.

[0544] Example 4, taking secondary carrier change / removal as an example.

[0545] It should be noted that in related technologies, once a secondary carrier is added, regardless of whether it is activated, the terminal needs to perform measurements on the secondary carrier to determine whether the secondary carrier needs to be changed or removed.

[0546] In this embodiment, the network-side device provides the terminal with first information (such as channel knowledge information), wherein the first information is related to secondary carrier change / removal, and the terminal performs secondary carrier change / removal based on the first information provided by the network-side device. Specifically, the network side provides channel knowledge-related information, and the terminal, based on the channel knowledge information and terminal location information provided by the network side, determines the secondary carrier signal quality and, optionally, triggers the transmission of a secondary carrier change / removal request.

[0558] Optionally, the channel knowledge map includes, but is not limited to, at least one of the following:

[0559] Channel Gain Map (CGM), Channel Shading Map (CSM), Channel Path Map (CPM), Line-of-Sight Link Probability Map, Dynamic Channel Knowledge Map.

[0560] The channel knowledge map includes channel information for different geographical regions or geographical locations and their associated information. The channel information may include one or more of the following: path loss, channel gain, signal reception quality (RSRP), shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information (path delay, path power, phase, angle, etc.), Rice factor, angle spread, and delay spread. Optionally, the channel information may also include CSI information, such as a periodic CSI change model. For example, in a smart factory scenario, the environment is relatively fixed, the driving path is relatively fixed, and the CSI change is also relatively fixed.

[0561] For example, the channel knowledge map includes a channel gain map, which contains channel gain information for different geographical regions or geographical locations and their associated channel gain information.

[0562] For another example, the channel knowledge map includes a line-of-sight link probability map, which contains the distribution and probability of LOS in different geographical areas, or the distribution and probability of LOS in different geographical locations.

[0564] Optionally, the angle information of the channel knowledge information can be the angle information of a few paths, such as the relevant information of the N strongest paths. For example, for a terminal in a certain geographical location, the channel information obtained from the channel knowledge map includes: the path power, phase, vertical departure angle (zenith AoD), and horizontal departure angle (azimuth AoD) of the three strongest paths.

[0565] It should be noted that the network side directly sends the channel knowledge map, and the terminal can directly obtain the corresponding channel knowledge based on the location information.

[0566] 2) Environmental information of at least one residential area

[0568] Optionally, the environmental information includes, but is not limited to, at least one of the following:

[0569] Radio map, sensing environmental point cloud information, 3D map.

[0570] The environmental information may include perceived environmental point cloud information, such as point cloud information reconstructed from the physical world, such as the physical world of a digital twin; or the environmental information may include radio maps, such as three-dimensional digital maps, representing information such as the height, width, length, and location of buildings in this way; or the environmental information may include 3D maps, which can represent information such as the height, width, length, and location of objects in the environment; the environmental information may also include the electromagnetic reflection coefficients of objects, building surfaces, point clouds, etc.

[0574] 4) Location information of at least one cell, base station, or TRP

[0583] Conditions for requesting to send a secondary carrier signal for on-demand measurement: secondary carrier or cell signal quality threshold.

[0584] S4-2. The terminal obtains location information.

[0585] The terminal's location can be obtained using 3GPP-based technologies or non-3GPP-based technologies; this embodiment does not impose any specific limitations. Furthermore, the terminal's location can be obtained through the transmission and reception of relevant signals on the primary carrier, such as communication signals, sensing signals, or positioning reference signals on the primary carrier.

[0586] S4-3. Determine whether to change or delete the secondary carrier based on the terminal location information and the first information.

[0587] The terminal estimates the signal quality based on the received first information and the terminal's location information. Similar to the above embodiment, the first information can be a channel knowledge map directly sent by the network, or channel information reconstructed by the terminal based on the radio environment sent by the network. The specific method is as described above and will not be repeated here.

[0588] Optionally, in conjunction with a signal quality threshold configured on the network side, the transmission of a first uplink signal is triggered. This first uplink signal can be used for:

[0589] A secondary carrier change or removal request; wherein the secondary carrier change or removal request may be sent via RRC signaling, or carried via MAC CE (optionally, different MAC CEs may be defined for secondary carrier change and secondary carrier removal), or carried via L1 signaling, such as UCI;

[0590] The secondary carrier requests the transmission of on-demand measurement signals. In one possible implementation, the network side configures a secondary carrier / cell signal quality threshold. When the signal quality estimated by the terminal based on channel knowledge information is higher or lower than the threshold, the terminal is triggered to send a first uplink signal. The first uplink signal is used to request the network to send on-demand measurement signals on the secondary carrier. The terminal performs measurements on the secondary carrier based on the received measurement signals and reports the measurement results.

[0591] Similar to Embodiment 2 above, in addition to the terminal side obtaining channel knowledge map or environmental information (such as RF map), and combining the terminal location to obtain channel signal quality, thereby triggering a secondary carrier change or removal request, or a secondary carrier on-demand measurement signal transmission request, in another implementation, the network side (base station) obtains channel knowledge map or environmental information, and based on the obtained terminal location information, the network side reconfigures the secondary carrier (changes or deletes it), or sends on-demand measurement signals.

[0592] The channel knowledge map or environmental information obtained by the network side is generated by the base station or sent to the base station by other base stations or the core network.

[0593] In this embodiment, the base station determines the terminal channel information based on the channel knowledge map or environmental information of multiple base stations or multiple TRPs, as well as the terminal location (physical location or virtual location), and reconfigures the secondary carrier (changes or deletes) or sends on-demand measurement signals based on the terminal channel information.

[0594] The terminal location can be obtained in at least one of the following ways:

[0595] The terminal reports location information or location area; wherein, the terminal location information or location area can be obtained by the terminal based on GNSS, or it can be obtained based on the downlink positioning method defined by 3GPP, such as DL PRS reference signal received power (DL PRS-RSRP), DL relative signal time difference (DL RSTD), UE Rx–Tx time difference, etc. as described in Example 1.

[0596] The network side obtains the terminal location; wherein, the network obtains the terminal location based on the uplink positioning method defined by 3GPP, such as gNB Rx–Tx time difference, UL Angle of Arrival (UL AoA), UL SRS reference signal received power (UL SRS-RSRP), etc. as described in Example 1.

[0597] The solution in this embodiment allows the terminal to obtain channel signal quality by using channel knowledge information sent by the network or reconstructed by the terminal, combined with the terminal's location. This reduces the terminal's measurement on the secondary carrier and helps to reduce terminal power consumption.

[0598] Example 5: Taking the alteration or removal of an auxiliary station as an example.

[0599] In this embodiment, the network-side device provides the terminal with first information (such as channel knowledge information), wherein the first information is related to the change or removal of auxiliary stations, and the terminal performs the change or removal of auxiliary stations based on the first information provided by the network-side device. Specifically, the network side provides channel knowledge-related information, and the terminal determines the signal quality of the auxiliary station based on the channel knowledge information and terminal location information provided by the network side, and optionally triggers the sending of an auxiliary station change or removal request.

[0600] Optionally, the first information is related to at least one of the following:

[0601] Path loss, channel gain, RSRP, shadow variance, shadow fading, spatial correlation matrix, AoA, AoD, multipath information, Rice factor, angle spread, delay spread, CSI.

[0602] Example 5 addresses a carrier aggregation scenario. Similar ideas can also be applied to adding, changing, or deleting secondary stations in dual connectivity (DC) scenarios.

[0603] The overall scheme of Embodiment 5 is the same as that of Embodiment 4 above. The difference is that Embodiment 4 is geared towards secondary carriers, while Embodiment 5 is geared towards secondary stations. For example, in this scenario, the first information includes triggering conditions for adding, changing, or removing secondary stations. The triggering conditions may be:

[0604] Auxiliary station addition conditions: Auxiliary station signal quality threshold

[0605] Auxiliary station deletion criteria: Auxiliary station signal quality threshold;

[0606] Conditions for changing auxiliary stations: signal quality threshold of the auxiliary station's service cell and signal quality threshold of the auxiliary station's neighboring cells.

[0607] Similar to Embodiment 4 above, the channel knowledge map or environmental information can also be stored on the network side. The network side or base station determines the terminal channel information based on the channel knowledge map or environmental information of multiple base stations or multiple TRPs, as well as the terminal location (physical location or virtual location), and reconfigures the auxiliary station (adds, changes, or deletes) based on the terminal channel information.

[0608] The other solutions are similar and will not be elaborated here.
