Each radio frame 118/124 may be further divided into sub-frames 120/127 which may include data symbols 122/128. In the present disclosure, the BS 102 and UE 104 are described herein as non-limiting examples of “communication nodes, ” generally, which can practice the methods disclosed herein. Such communication nodes may be capable of wireless and/or wired communications, in accordance with various embodiments of the present solution.

FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM/OFDMA signals) in accordance with some embodiments of the present solution.

In one illustrative embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of FIG. 1, as described above.

System 200 generally includes a base station 202 (hereinafter “BS 202” ) and a user equipment device 204 (hereinafter “UE 204” ) .

The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232.

Systems and Methods for Sensing and Positioning Assisted Mobility Management

Embodiments #1: Base station notifies the mapping relationship between velocity and measurement report cycle.

In the mobile communication network, the network 100 may manage the movement of terminals 104 and may optimize links between the terminals 104 and the network 100, thereby providing an application of one or more network services. The terminals 104 may move from the coverage area of one BS 102 o the coverage area of another BS 102. There may be differences in the movement of the terminals 104 in the network 100. For example, one or more terminals 104 may be on high-speed trains, whereas one or more terminals 104 may be moving at a lower speed or stationery. The BS 102 can notify the mapping relationship between velocity and measurement report cycles to the terminals 104. In response to the velocity of the terminals 104, the BS 102 can set different measurement cycles. The BS 102can notify mapping relationships between velocity thresholds and measurement report cycles to the terminals 104. For example, one BS 102 sets the velocity threshold to six levels.

One level of the six levels can be <5km/h, 20480ms>, which indicates that when the velocity of the terminals is less than 5km/h, the reporting cycle is 20480 ms. Another level of the six levels can be <20km/h, 5120ms>, which indicates that when the velocity of the terminals is more than 5km/h and les than 20km/h, the reporting cycle is 5120 ms. Another level of the six levels can be <80km/h, 1024ms>, which indicates that when the velocity of the terminals is more than 20km/h and les than 80km/h, the reporting cycle is 1024 ms. Another level of the six levels can be <120km/h, 640ms>, which indicates that when the velocity of the terminals is more than 80km/h and les than 120km/h, the reporting cycle is 640 ms. Another level of the six levels can be <200km/h, 240ms>, which indicates that when the velocity of the terminals is more than 120km/h and les than 200km/h, the reporting cycle is 240 ms. Another level of the six levels can be <500km/h, 120ms>, which indicates that when the velocity of the terminals is more than 5km/h and les than 20km/h, the reporting cycle is 120 ms.

The slower the velocity of the terminal 104, the larger the measurement reporting cycle can be set. The BS 102 can notify the mapping relationship between velocity thresholds and measurement report cycles to the terminals 104 by unicast or broadcast as depicted in FIG. 3. FIG. 3 illustrates an example 300 for notifying the velocity threshold. One terminal 104 may receive the mapping relationship between velocity thresholds and measurement report cycles and reports the measurement report based on the velocity of itself. The terminal 104 can obtain its own velocity. FIG. 3 illustrates that the BS 102 can transmit one or more signals to the terminal. The one or more signals can be used to measure the velocity of the terminal 104. FIG. 3 further illustrates that the terminal 104 can receive the one or more signals and derive the velocity from the one or more signals. In some arrangements, the terminal 104 can adjust a measurement report cycle based on the velocity and a mapping relationship between velocity thresholds and measurement report cycles. In some arrangements, the BS 102 can notify the measurement report cycles to the terminal 104 and the terminal 104 can adjust measurement report cycle based on signal information.

The BS 102 can measure the one or more transmitted signals by the terminal 104 and can obtain the velocity of the terminal. The BS 102 can notify the velocity to the terminal 104, the terminal 104 can adjust the measurement report cycle based on the velocity and the mapping relationship between velocity thresholds and measurement report cycles. The BS 102 can notify the measurement report cycles to the terminal 104 and the terminal 104 can adjust the measurement report cycle based on the signal information. If the BS 102 updates the mapping relationship between velocity thresholds and measurement report cycle and can notify a new mapping relationship between velocity thresholds and measurement report cycles to the terminals 104. The terminals 104 can update its parameters and use the new mapping relationship between velocity thresholds and measurement report cycles.

The BS 102 can request the mapping relationships between velocity thresholds and measurement report cycles. The BS 102 can request the mapping relationships between velocity thresholds and measurement report cycles from another function (e.g., Access and Mobility Management Function (AMF) , Location Management Function (LMF) , among others) . FIG. 4 illustrates an example for a process of the velocity threshold configuration with another function. For example, the BS 102 can send a velocity threshold request message to an AMF 402, and the AMF 402 can respond with a velocity threshold request message. before the BS 102 can send the velocity threshold response message, the BS received the velocity threshold response message from the AMF 402. The velocity threshold response message can be sent by the AMF 402 or based on the velocity threshold request message.

Embodiment #2: Base Station or Core Network indicates the measurement configuration

A wireless communication system of the present disclosure can automatically support positioning, sensing, and communication. Positioning refers to the transmission and reception of signals between the BS 102 and the terminal 104 to calculate the position of the terminal. Sensing refers to the use of signals in the wireless communication system to obtain characteristics of the environment and/or objects in the environment. The wireless communication system can utilize the reflection or scattering of signals in the wireless communication system to obtain characteristics of the environment and/or objects in the environment.

The wireless communication system can optimize terminal mobility management by utilizing the positing of the terminal 104 and the characteristics of the environment and/or objects in the environment. In a 5G mobile communication system, the terminal 104 can measure one or more reference signals (e.g., single-sideband modulation (SSB) or channel state information-reference signal (CSI-RS) ) sent by the BS 102 to receive cell signal quality. The BS 102 can inform the terminal 104 of the resources occupied by signals (e.g., SSB or CSI-RS) . In conventional solutions, the terminal 104 can report the measurement results, based on the reporting cycle negotiated with the BS 102. The terminal 104 can report the measurement result based on events. The terminal can measure the received SSB and/or CSI-RS and report the measurement result to the BS 102. The terminal can measure all the received SSB and/or CSI-RS, which uses a significant number of resources and is not conductive to UE 104 power saving.

To combat this pitfall, the BS 102 of the present disclosure can send measurement configuration messages to the terminal 104 to configure the terminal 104 to detect which SSB or CSI-RS can or cannot be measured. FIG. 5 illustrates an example for an environment within the coverage of a BS 102. Referring to FIG. 5, a BS 102 can use a plurality of beams to send an SSB. The BS 102 can send an indication information to one or more terminals 104. The indication information can indicate resources used in sending the plurality of beams, where terminal A 104 and terminal B 104 are associated with the BS 102. There may be one or more obstacles (e.g., trees, buildings, vehicles, people, poles, etc. ) between terminal A 104, terminal B 104, and the BS 102. The obstacles can block a line of sight (LoS) transmission between the BS 102 and the terminals 104.

A mobile system described herein can sense the obstacles or obtain positions of the terminals 104. Using the positions of the terminals 104, the mobile system can detect one or more beams in the plurality of beams that can measure the terminal A 104 or terminal B 104. Therefore, the BS 102 can recommend the detected one or more beams for the terminals 104 to use to measure and report signals. For example, the BS 102 can recommend that terminal A 104 measure and report via beam #1, beam #3 and beam #4. The BS 102 can notify terminal A 104 by indicating wireless resources corresponding to beam #1, beam #3 and beam #4. Each wireless resource corresponds to time-frequency domain resources of a beam. When beam#1 is not line of sight (NLOS) , the BS 102 can indicate the wireless resource corresponding to beam #1 is NLOS. Furthermore, the BS 102 can indicate LOS or NLOS for each wireless resource. The BS 102 can notify terminal B 104 by indicating the wireless resources corresponding to beam #5 and beam #8. Each wireless resource corresponds to the time-frequency domain resources of the beam. If beam#5 and beam#8 are NLOS, the BS 102 can indicate the wireless resource corresponding to beam #5 and beam#8 are NLOS.

The terminals 104 can prioritize reporting the cell signal quality about beams recommended by the BS 102. Each beam can correspond to a set of measurement parameters (e.g., Reference Signal Received Power (RSRP) , Reference Signal Received Quality (RSRQ) , wireless resource ID, etc. ) . FIG. 6 illustrates an example for a process for mobility management. If the terminals 104 can determine that the measured wireless resource is NLOS or LOS, the terminal 104 can indicate the measured wireless resource is NLOS or LOS. The measured wireless resource can include a format where the format is <wireless resource ID 1, RSRP and/or RSRQ, LOS>or <wireless resource ID 2, RSRP and/or RSRQ, NLOS>.

Embodiment #3: Base Station configures Good Area List to terminals

The wireless communication system can obtain the characteristics of the environment and/or objects within the environment (e.g. shape, size, orientation, speed, location, distances or relative motion between objects, etc. ) using RF signals. The wireless communication system can learn the environment within the coverage of each BS 102. FIG. 7 illustrates an example for a good area list, the wireless communication system can obtain characteristics of objects in the environment. The objects may block the transmission between BS 102 A and terminals 104. Therefore, the wireless communication system can calculate some good areas based on the characteristics of the environment and/or objects in the environment.

The good area can be defined as an area where terminals 104 and the BS 102 have a LOS path and an area where terminals 104 meet cell selection criterion S. The good area can be estimated by the system based on the capabilities of the BS 102 (e.g., transmission power, bandwidth, number of antennas, and/or the distance between the BS 102 and the area) . In some case, based on the distance, a path lost can be obtained. The good area can be further defined as an area where the distance from the BS 102 is within a specific range, an area where the angle with the normal direction of the BS 102 is within a specific range, and an area where the time of radio wave transmission and the BS 102 is within a certain range.

The wireless communication system can derive the good areas based on the characteristics of the environment and/or objects within the environment as the BS 102 notifies terminals 104 the good area lists. The good area list can include good area list information. The good area list information can include a Good area ID, a Good area distance range, a Good area angle range, a Good area time range, and a Geographical area.

For ease of description, the Good area distance range is indicated by a minimum distance, a maximum distance or a combination of minimum distance and maximum distance. For ease of description, the Good area angle range is indicated by a minimum angle, a maximum angle or a combination of minimum angle and maximum angle. For ease of description, the Good area time range is indicated by a minimum time, a maximum time or a combination of minimum time and maximum time. For ease of description, the Geographical area is indicated by latitude and longitude. In some arrangements, the BS 102 can send a good area list information to terminals 104. The good area list information includes a good area list.

Furthermore, if the terminal knows the terminals 104 position and the location of the terminal is within one area indicated by the good area list information and the serving cell meets the cell selection criterion S, the terminal may not report the measurement result. The measurement result includes intra-frequency measurement and/or inter-frequency measurement.

Furthermore, the BS 102 receives the good area list information and the positioning of terminals 104 from other functions such as sensing function (SF) , location management function (LMF) and so on. The functions and so on are located in core network or radio access network (RAN) .

FIG. 8 illustrates an example for the SF 802 notifying the good area list, the SF 802 notifies the BS 102 the good area list information. The SF 802 can send the good area list information actively or based on a request from the BS 102. The BS 102 can send a good area list request information to the SF 802. The good area list request information can include the BS 102 ID, a Request type, and the Good area list. For ease of description, the BS 102 ID can indicate the identification of the BS 102 such as TRP ID, cell ID and so on. For ease of description, the request type can indicate the request is the period request or event-based request. The SF 802 can send a good area list response information, the good area list response information can include the BS 102 ID, a response type, and the Good area list. For ease of description, the response type is used to indicate the response is the period response or event-based response.

In some cases, if the response type is a period response, the good area list response information can further include a period and a next sending time. In some cases, if the response is event-based response, the good area list response information can further include an Event typ. The event type can indicate an event. The event can be at least one of a terminal is re-associated with the BS 102, speed of the terminal changes, positioning of the terminal changes, or signal quality of the terminal changes.

The BS 102 can send notification messages to indicate whether the terminal is located in a good area. FIG. 9 illustrates an example for notifying the good area list. The terminal area notification message can define whether the terminal is in a good area or not.

Furthermore, if the terminal knows the terminals 104 position and the location of the terminal is within one area indicated by the good area list information and the serving cell meets the cell selection criterion S, the terminal may not report the measurement result. The measurement result includes intra-frequency measurement and/or inter-frequency measurement. Furthermore, the BS 102 receives the terminal area notification messages from other functions such as SF, LMF and so on. The functions and so on are located in core network or RAN.

FIG. 10 illustrates an example for a process for terminal area notification information, the SF 802 notifies the terminal area response information. The SF 802 can send the terminal area response information actively or based on the request from the BS 102. The BS 102 can send a terminal area request information to the SF 802, the terminal area request information can include the BS 102 ID, the Request type, and a terminal ID list. For ease of description, the request type can indicate the terminal area request. For ease of description, the terminal ID list can indicate a set of terminal identifiers to list the terminals 104 which are requested whether they are in good areas. The SF 802 can send a terminal area response information. The terminal area response information can include the BS 102 ID and a List of <terminal ID, status>. The List of < terminal ID, status>can indicate the terminals 104 and the status of these terminals 104 remaining in the good areas.

Embodiment #4: Network Initiated Cell Handover

The wireless communication system can obtain characteristics of objects in the environment and positioning of the terminals 104. The wireless communication system can derive the good areas of each BS 102 based on sensing data collected from the base stations and terminals 104. In the wireless communication system, different base stations may have different environments and different obstacles. Therefore, different base stations may have different good areas. FIG. 11 illustrates an example the good areas of multiple base station. As depicted in FIG. 11, BS 102 A and BS 102 B have overlapping areas. Within the overlapping area, there are obstacles between BS 102 A and terminal 104 A, whereas there are no obstacles between BS 102 B and terminal 104 A. Therefore, the signal quality between BS 102 A and terminal 104 A may be worse than the signal quality between BS 102 B and terminal 104 A.

When terminal 104 A moves from the coverage of BS 102 A to the coverage of BS 102 B, terminal 104 A can enter the good area C of BS 102 B. Thus, the network 100 can initiate cell handover, as shown in FIG. 12.FIG. 12 illustrates an example network 1302 initiating cell handover. The core network 1202 can initiate the handover and issue a HANDOVER RECOMMENDATION. The HANDOVER RECOMMENDATION can include a UE ID to indicate which UE are recommended to switch to a new BS 102 and a target BS 102 list. The target BS 102 list can one or more potential target base stations (e.g., target BS 102 ID) and/or their recommendation reason (e.g., recommended reason list) . The recommended reason list can include one or more reasons such as the UE in the good area, LOS between UE and the base station, and the cell measurement meets cell selection criterion S with this base station.

The source gNB can initiate handover and issue a HANDOVER REQUEST over the Xn interface. The target gNB can perform admission control and provide a new RRC configuration as part of a HANDOVER REQUEST ACKNOWLEDGE. The source gNB can provide the RRC configuration to the UE by forwarding the RRCReconfiguration message received in the HANDOVER REQUEST ACKNOWLEDGE. The RRCReconfiguration message can include the cell ID and information required to access the target cell so that the UE can access the target cell without reading system information. In some cases, the information required for contention-based and contention-free random access can be included in the RRCReconfiguration message. The access information to the target cell may include beam specific information. Lastly, the UE moves the RRC connection to the target gNB and replies with the RRCReconfigurationComplete.
