Description

Electronic device and method for wireless communication, and information processing device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on May 27, 2022, with application number 202210586272.9 and invention name “Electronic device and method for wireless communication and information processing device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technology, and more specifically, to an electronic device and method for wireless communication, an information processing device, and a non-transitory computer-readable storage medium that facilitates determining a downlink beam. Background Art

[0003] With the development of technology, there are more and more scenarios where people carry user equipment (UE) and move at high speeds while expecting to carry out wireless communications as usual. For example, when people travel at high speed on a high-speed vehicle (a ground vehicle such as a train or a low-lying vehicle such as an airplane), the UE they carry moves at high speed within the coverage area of ​​​​the base stations along the way (ground base stations or base stations in non-terrestrial networks (NTN)) and quickly passes through the coverage area of ​​different downlink beams within the coverage area of ​​each base station (each cell).

[0004] Furthermore, with the increasing adoption of non-terrestrial networks, in many scenarios, base stations in these networks use or control satellites moving relative to the ground or high-speed, high-altitude platforms to transmit downlink beams to user devices. Without fixed beam technology, the projection of the wireless communication beams used by base stations in these non-terrestrial networks on the ground would move rapidly, at speeds of up to several kilometers per second. In this case, user devices would pass through the coverage area of ​​each base station's downlink beam more quickly.

[0005] In cases where the beam coverage time of each beam is short, such as but not limited to the above scenario, in order to ensure that the base station always uses the appropriate downlink beam to send data to the UE, beam measurement of the downlink beam needs to be continuously performed between the base station and the UE so that the base station can perform beam switching based on the results of the beam measurement.

[0044] Examples of the present disclosure will now be described more fully with reference to the accompanying drawings.The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

[0045] Example embodiments are provided so that the present disclosure will be exhaustive and will fully convey its scope to those skilled in the art.

[0046] The description will be in the following order:

[0047] 1. Overview

[0048] 2. Configuration Example of Electronic Device of First Embodiment

[0049] 3. Configuration Example of Electronic Device of Second Embodiment

[0050] 4. Configuration Example of Information Processing Device of Third Embodiment

[0051] 5. Method Examples

[0052] 6. Application Examples

[0053] <1. Overview>

[0054] As previously mentioned, when people travel at high speed, for example, on a high-speed vehicle (a ground vehicle such as a train, or a near-ground vehicle such as an airplane), the user equipment they carry moves at high speed within the coverage area of ​​base stations along the route (ground base stations or base stations in non-ground networks), or even within the coverage area of ​​different downlink beams of each base station. Furthermore, in non-ground networks, the projection of wireless communication beams on the ground, transmitted by satellites (low-orbit satellites or medium-orbit satellites) or high-speed high-altitude platforms moving relative to the ground under the control of base stations, also moves rapidly.

[0055] In the scenario where the user equipment moves at high speed and / or the beam projection used by the base station in the non-ground network providing services for the user equipment moves rapidly, the user equipment will quickly pass through the coverage areas of different downlink beams.

[0056] As an example, Figures 1A and 1B illustrate an aircraft's route through satellite beams. In the example of Figure 1A , a base station (gNB) in a non-terrestrial network is located on the ground and communicates with terrestrial core network equipment (not shown). The gNB's satellite cell is covered by two low Earth orbit (LEO) satellites as transmission access points (TRPs). Specifically, the gNB uses different beams from satellite LEO-1, Beam 1 and Beam 2, and different beams from satellite LEO-2, Beam 3 and Beam 4, within the same cell. As an aircraft passes through the gNB's satellite cell, it will be located in the coverage areas of Beams 1 through 4, and the UEs on the aircraft will experience three beam switching operations. The example of Figure 1B differs from that of Figure 1A in that satellites LEO-1 and LEO-2 are non-transparent satellites. That is, satellites LEO-1 and LEO-2 themselves function as base stations in the non-terrestrial network and communicate directly with terrestrial core network equipment (not shown). At this time, when the aircraft passes through the satellite cell of LEO-1 or LEO-2, it will also be located in the coverage area of ​​different beams, and the UE on the aircraft will experience one beam switching.

[0057] Figure 1C shows an example of satellite beams and related parameters for high-speed vehicles, and Figure 1D shows an example of the beam coverage time of a LEO satellite beam relative to an aircraft, calculated using the parameters in Figure 1C and without beam fixation. As shown in Figure 1D, due to the movement of the aircraft itself and the movement of the beam projection, the time an aircraft (or a user equipment (UE) on board) is covered by a beam becomes very short. Specifically, in this example, assuming that the direction of movement of the beam projection on the ground is exactly the same as the aircraft's flight direction, the aircraft's coverage time is only 6.51 seconds if the beam projection has a diameter of 50 kilometers, and 130 seconds if the projection diameter is 1000 kilometers. If the beam projection moves in the opposite direction to the aircraft's flight direction, the above two times become 6 seconds and 120 seconds. In either case, the beam coverage time is very short.

[0058] In this case where the beam coverage time of each beam is short, in order to ensure that the base station always uses the appropriate downlink beam to send data to the UE, beam measurement of the downlink beam needs to be continuously performed between the base station and the UE so that the base station can switch the beam according to the results of the beam measurement.

[0059] The inventors of the present disclosure have noticed that the beam coverage time of each beam in scenarios such as the above is short, and for this situation, they proposed an inventive concept of using an appropriate downlink beam for data transmission based at least in part on the relationship between the location of the user equipment and the coverage overlap area of ​​the current beam and the next beam used for the user equipment, thereby reducing dependence on beam measurement.

[0060] Next, the apparatus and method according to the embodiments of the present disclosure will be further described. Note that although the above overview and the following detailed description partially describe application scenarios in which a user device is on a vehicle and / or is served by a base station in a non-terrestrial network as examples, the embodiments of the present disclosure are not limited to the above application scenarios, but can be appropriately applied to any scenario with a short beam coverage time, and will not be further described here.

[0061] <2. Configuration Example of Electronic Device of First Embodiment>

[0062] (Configuration Example)

[0063] FIG2 is a block diagram illustrating an example configuration of an electronic device according to the first embodiment of the present disclosure. The electronic device illustrated in FIG2 can be used on the base station side, for example, a base station-side device in a non-terrestrial network, such as the base station gNB illustrated in FIG1A or the non-transparent satellite (with base station functionality) LEO-1 or LEO-2 illustrated in FIG1B .

[0064] As shown in Figure 2, the electronic device 100 may include a control unit 110 and a transceiver unit 120. The control unit 110 may control the overall operation of the electronic device 100, and the transceiver unit 120 may, for example, under the control of the control unit 110, send information to a device outside the electronic device 100 and / or receive information from a device outside the electronic device 100. In addition, although not shown in the figure, the electronic device 100 may further include a storage unit.

[0065] Here, each unit of the electronic device 100 may be included in a processing circuit. It should be noted that the electronic device 100 may include either one processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0066] According to the first embodiment, the control unit 110 of the electronic device 100 can determine one or both of the current beam and the next beam as the used beam based at least in part on the relationship between the location of the user equipment and the coverage overlap area of ​​the current beam (current downlink beam) and the next beam (next downlink beam) used for the user equipment.

[0067] 3 is a block diagram showing a configuration example of the control unit 110 of the electronic device 100. As shown in FIG3, the control unit 110 may include a beam area determination unit 111 and a used beam determination unit 112.

[0068] The beam area determination unit 111 can obtain the position of the user equipment and determine the current beam, next beam and coverage overlap area for the user equipment accordingly. The coverage overlap area has edges, including an entry side edge where the user equipment enters the area and an exit side edge where the user equipment leaves the area.

[0069] The beam area determination unit 111 can obtain the position of the user equipment in various ways. For example, the beam area determination unit 111 can receive position information reported by the user equipment (e.g., real-time reporting, periodic reporting, reporting at a predetermined location, or reporting when other predetermined conditions are met) via the transceiver unit 120 of the electronic device 100. The position information includes, for example, the geographic location of the user equipment, (optional) altitude, time (measurement time of obtaining the geographic location / altitude), etc.

[0070] In a preferred example, the user equipment may be on a vehicle having a predetermined moving path, and the beam area determination unit 111 may receive information about the predetermined moving path of the vehicle from another device (such as an information processing device such as a server provided in a core network or a cloud service platform) via the transceiver unit 120 of the electronic device 100. The information about the predetermined moving path of the vehicle may include, for example, information indicating the following: an identifier (ID) of the vehicle and / or a number of the moving path (flight number / train number, etc.), a geographic location on the moving path (and optionally an altitude), a time associated with the geographic location on the moving path (and optionally an altitude), and the like. Optionally, the information may also include information indicating a moving direction (associated with a geographic location on the moving path (and optionally an altitude) and a time).

[0071] The beam area determination unit 111 can determine the current position of the user equipment and obtain the predicted position of the user equipment based on the relevant information obtained, so as to determine the current beam and the next beam for the user equipment. For example, when continuously obtaining the position information reported by the user equipment, the control unit 110 can determine the current position of the user equipment based on the current position information, and can estimate the movement path (including the movement direction) of the user equipment based on the previous and current position information to obtain the predicted position of the user equipment. When receiving information about the predetermined movement path of the vehicle where the user equipment is located from another device, the control unit 110 can obtain the current position and predicted position of the user equipment based on the association of the geographical location (and optional altitude) and time in the information.

[0072] The beam area determination unit 111 can determine the current beam and the next beam for the user equipment based on the current position and the predicted position of the user equipment obtained, for example, in the above manner, in combination with the coverage area of ​​each downlink beam controlled by itself (a downlink beam emitted by the electronic device 100 having a base station function itself or other devices controlled by the electronic device 100, such as TRP or a transparent satellite). In the present disclosure, as an example, the center position of the coverage range of a beam (the position where the beam quality of the beam is the highest) and the area with a given beam quality as the boundary (i.e., with a given beam quality (e.g., a signal strength of -140dBm) as an isoline) can be defined as the coverage area of ​​the beam.

[0073] As an example, the beam area determination unit 111 may determine a beam whose coverage area includes the current location of the user equipment as the current beam for the user equipment, and determine a beam whose coverage area includes the predicted location of the user equipment and is immediately adjacent to the current beam in the moving direction of the user equipment as the next beam for the user equipment. Note that this means that the predicted location of the user equipment is separated from the current location of the user equipment by a certain distance, which can be achieved through appropriate processing when the beam area determination unit 111 estimates the predicted location (for example, estimating the predicted location after moving for a certain time and / or distance, continuously estimating multiple predicted locations, etc.).

[0074] The beam area determination unit 111 can further determine the coverage overlap area of ​​the current beam and the next beam for the user equipment, that is, the overlap area of ​​the coverage area of ​​the current beam and the coverage area of ​​the next beam (also referred to as the overlap area in this article as appropriate). As mentioned above, in the present disclosure, the area around the center of the coverage range of a beam and bounded by a given beam quality is taken as the coverage area of ​​the beam, so that the boundaries (or edges) of the coverage areas of two adjacent beams defined in this way will intersect, and the area within the intersection range is the coverage overlap area. The beam area determination unit 111 preferably determines the entry side edge of the coverage overlap area, and optionally also determines the exit side edge of the coverage overlap area.

[0075] Optionally, the beam area determination unit 111 can use the transceiver unit 120 of the electronic device 100 to provide the user equipment with one or more of information about the current beam, information about the next beam, and information about the edge of the coverage overlap area. The information about the current / next beam includes but is not limited to the beam indication information of the beam, and the information about the edge of the coverage overlap area includes but is not limited to the location information of the edge. Optionally, the beam area determination unit 111 can use the transceiver unit 120 of the electronic device 100 to forward the information about the predetermined movement path of the vehicle to the user equipment on the vehicle (described later) when appropriate.

[0076] The beam determination unit 112 may determine one or both of the current beam and the next beam as the used beam according to one or more predetermined rules, at least in part based on the relationship between the position of the user equipment obtained by the beam area determination unit 111 and the coverage overlap area determined by the beam area determination unit 111, in particular, the edge of the coverage overlap area.

[0077] In one example, the predetermined rule for using the beam determination unit 112 to determine the use of the beam may include determining whether to perform beam measurement based on a relationship between the location of the user equipment and an edge of the coverage overlap area, and determining to use the beam based on the relationship and, optionally, in combination with a result of the beam measurement. In another example, the predetermined rule for using the beam determination unit 112 to determine the use of the beam may include determining to use the beam without performing beam measurement based solely on the relationship between the location of the user equipment and an edge of the coverage overlap area.

[0078] After the control unit 110 determines one or both of the current beam and the next beam as the beam to be used based on a predetermined rule, for example, using the beam to be used determination unit 112 as shown in FIG3 , the transceiver unit 120 may transmit data to the user equipment using the beam to be used. Optionally, the transceiver unit 120 may pre-provide the user equipment with information related to the predetermined rule used by the control unit 110 (beam to be used determination unit 112) to determine the beam to be used (described later).

[0079] The above describes the configuration example of the electronic device 100 of the first embodiment. Utilizing the electronic device 100 of this embodiment can reduce reliance on beam measurements. For example, the number of beam measurements performed can be reduced, thereby facilitating reduction in energy consumption and signaling interactions associated with beam measurements.

[0080] Next, example processing performed by the electronic device 100 using various units, especially the control unit 110 thereof, will be further described with appropriate combination of example scenarios.

[0081] (Example Processing of Beam Region Determination)

[0082] In this example, the user device is on a vehicle with a predetermined movement path, and the electronic device 100 can use the control unit 110 (e.g., the beam area determination unit 111) to receive information about the predetermined movement path of the vehicle from another device (such as an information processing device such as a server set in a core network or a cloud service platform) via the transceiver unit 120, and can determine the position of the user device, the current beam, and the next beam based at least in part on the information about the predetermined movement path. The electronic device 100 can also use the control unit 110 (e.g., the beam area determination unit 111) to further determine the coverage overlap area (including the edge of the coverage overlap area) based on the determined coverage areas of the current beam and the next beam.

[0083] FIG4 schematically shows an example of the coverage area of ​​the current beam and the next beam controlled by the electronic device 100 for a user equipment UE on an airplane. The electronic device 100 may, for example, obtain information about the flight path R of the airplane shown in FIG4 from another device, and may utilize the control unit 110 (beam area determination unit 111) to determine the location of the user equipment at various times based on the association between the geographic location and altitude in the information and time, and based on this, in combination with the coverage area of ​​the downlink beam controlled by the electronic device 100, obtain the beam for the user equipment at various times, including the current beam B shown in FIG4. C and the next beam B N .

[0084] The electronic device 100 can further utilize the control unit 110 (beam area determination unit 111) to determine the beam area according to the current beam B. C and the next beam B N The boundaries of the beam intersect at points I and I', determining the current beam B C The boundary between points I and I' is the edge of the incoming side L1, the next beam B N The boundary between points I and I' is the exit side edge L2, and the coverage overlap area between the entry side edge L1 and the exit side edge L2 is then determined. Optionally, the electronic device 100 can further use the control unit 110 (beam area determination unit 111) to determine the predicted position of the user device at the edge (such as the predicted entry position P1 and the predicted exit position P2 shown in Figure 4) based on the predetermined movement path of the vehicle (such as the route shown in Figure 4) and the position of the edge of the coverage overlap area (such as the entry side edge L1 and the exit side edge L2 shown in Figure 4).

[0085] The electronic device 100 may provide one or more of information about the current beam, information about the next beam, and information about the coverage overlap area (the edge of the coverage overlap area) to the user device, for example, via the transceiver unit 120. As an example, the information about the edge of the coverage overlap area may indicate at least one of the following: the position of the edge of the coverage overlap area (such as the position of the edge L1 and / or L2 shown in FIG4 ); and the predicted position of the user device at the edge determined based on the predetermined movement path and the position of the edge (such as the predicted position P1 and / or P2 shown in FIG4 ). Optionally, in the case where a relevant determination is made based on the information about the predetermined movement path of the vehicle, the electronic device 100 may also provide the information about the predetermined movement path of the vehicle to the user device via the transceiver unit 120 for the latter's reference.

[0086] Figure 5 schematically shows an example information interaction related to the above-mentioned beam area determination example processing between a base station side device (gNB) having the functions of the electronic device 100, a user equipment UE, and an information processing device (Server) such as a server for providing movement path information of a vehicle.

[0087] As shown in Figure 5, the gNB (electronic device 100 for gNB) can, for example, pre-acquire (or continuously acquire) information about the movement path of a vehicle and, after a user equipment (UE) accesses the gNB after takeoff or during flight, optionally obtain location information reported (or periodically or periodically reported) by the UE upon accessing the gNB. Based on the information about the movement path of the vehicle, optionally in combination with the location information reported by the UE, the gNB (electronic device 100 for gNB) can determine the UE's location, current beam, and next beam in the manner previously described, and further determine the edge of the coverage overlap area, and provide the UE with information about the current beam, next beam, and the edge of the coverage overlap area. Optionally, although not shown, the gNB may also provide the UE with information about the vehicle's predetermined movement path, along with or in addition to this information. The gNB may also provide the UE with information about one or more predetermined rules for subsequent beam determination at the base station (described later), along with or in addition to this information.

[0088] In the example shown in Figure 5, electronic device 100 for a gNB can determine that a UE is on a vehicle by comparing information about the vehicle's movement path with the location information reported by the UE. After the UE accesses the gNB, the gNB and UE can perform various procedures for reporting location information, determining the edges of the current / next beams and the overlap area, and notifying the UE of relevant information such as the edges of the current / next beams and the overlap area. These procedures can be performed periodically, after the UE passes an edge location, or after a beam switch occurs.

[0089] In one example, the electronic device 100 may be a non-ground network base station (e.g., the gNB shown in FIG. 1A or the LEO-1 or LEO-2 shown in FIG. 1B ), and may utilize the control unit 110 (beam area determination unit 111) to determine the current beam and the next beam of the user equipment based on information about the predetermined moving path of the vehicle, and further based on the ephemeris map of the satellite that transmits the downlink beam controlled by the non-ground network base station (and optionally the geographic location of the satellite). For example, the electronic device 100 may utilize the control unit 110 (beam area determination unit 111) to determine the movement trajectory of the coverage area of ​​each beam based on the ephemeris map of the satellite, and obtain the beam for the user equipment at each time based on the movement trajectory of the coverage area of ​​each beam and the position of the user equipment at each time determined based on the association between the geographic location / altitude and time in the information about the predetermined moving path of the vehicle, such as the current beam B shown in FIG. C and the next beam B N In this case, in the example of FIG5 , the electronic device 100 for the gNB may, for example, obtain information on the ephemeris map and / or geographic location of the satellite in advance.

[0090] In addition, although not shown in the example of FIG. 5 , the electronic device 100 can optionally utilize the control unit 110 (beam area determination unit 111) to start a timer set for updating the satellite's ephemeris map and / or geographic location (and optionally, the satellite antenna pattern) after the user equipment (UE) accesses the non-ground network base station (gNB). After the timer expires, it determines whether the ephemeris map and / or geographic location (and optionally, the satellite antenna pattern) of the satellite controlled by the non-ground network base station has been updated. If an update occurs, the user equipment's current beam and next beam are determined based on the updated ephemeris map and / or geographic location (and optionally, the updated satellite antenna pattern) (and optionally, the edge of the coverage overlap area). Optionally, the electronic device 100 can also provide the user equipment with the updated information. The above-mentioned timer can be periodic or aperiodic. Using this timer, the accuracy of the determination of the current beam, the next beam (and optionally, the edge of the coverage overlap area) can be ensured.

[0091] The information about the current beam, the next beam and the edge of the coverage overlap area obtained from the electronic device 100 (and optionally the information about the predetermined movement path of the vehicle, and the predetermined rules for determining the use of the beam) can enable the user device itself to monitor whether it is in the coverage overlap area (for example, whether it has reached the edge of the coverage overlap area) and know the beam area it is in (and possibly the beam it is using, as described later).

[0092] In the actual operation of transportation vehicles, such as airplanes, buses, ships, and even trains, the actual path may deviate from the planned path. Figure 6 schematically illustrates an example of a UE on an airplane passing through the coverage areas of the current beam and the next beam, where the actual route R' of the airplane deviates from the planned route R. In this case, the actual position (P1', P2') of the user equipment at the edge (L1, L2) of the overlapping coverage area may be inconsistent with the predicted position (P1, P2) of the user equipment at the edge, as indicated by the information regarding the edge of the overlapping coverage area provided by the electronic device 100.

[0093] In view of the above situation, when the information about the edge of the coverage overlapping area obtained by the user equipment from the electronic device 100 indicates that the user equipment has reached the predicted position of the edge, the user equipment may send a deviation report indicating the inconsistency to the electronic device when the actual position of the user equipment at the edge is inconsistent with the predicted position. Accordingly, the electronic device 100 may receive, via the transceiver unit 120, a deviation report indicating the inconsistency sent by the user equipment when the actual position of the user equipment at the edge is inconsistent with the predicted position. Optionally, the electronic device 100 may use the control unit 110 (e.g., the beam area determination unit 110) to refer to the deviation report to (subsequently) determine the position of the user equipment, the current beam, and the next beam.

[0094] Figure 7 schematically illustrates some example information exchange related to the aforementioned deviation reporting between a base station device (gNB) and a user equipment (UE) having the functionality of electronic device 100. As shown in Figure 7, for example, after a UE passes over the edge (L1, L2) of a coverage overlap area at an actual position (P1', P2') that differs from a predicted position (P1, P2), it generates and transmits a deviation report indicating this discrepancy to the gNB (having the functionality of electronic device 100). The deviation report may, for example, take the form of deviation values ​​(P1'-P1, P2'-P2). The gNB may use this deviation report to correct the UE's position and the movement path of the vehicle in which the UE is located. For example, the gNB may add the deviation values, such as (P1'-P1) and / or (P2'-P2), or their average, to the UE's current position, next position, or all subsequent positions indicated by information regarding the vehicle's predicted movement path to achieve this correction. Based on the corrected movement path, the gNB may determine the subsequent UE position, current beam, next beam, and, optionally, the edge of the subsequent coverage overlap area in the manner previously described. Although not shown in Figure 7, the gNB can provide the UE with information about the current beam, information about the next beam, and information about the edge of the coverage overlap area, determined in the manner described above through the correction process. The example process of Figure 7 can be performed each time the aircraft passes over the edge of the coverage overlap area, so that corrections are continuously made based on the latest deviations.

[0095] (Example Processing Using Beam Determination)

[0096] In this example, consider an electronic device 100, for example, using a control unit 110 (using a beam determination unit 112) to determine one or both of a current beam and a next beam as related example processing using a beam based at least in part on a relationship between a position of a user device and an edge of a coverage overlap area (e.g., obtained using a beam area determination unit 111) according to one or more predetermined rules determined using a beam.

[0097] As an example, the electronic device 100 can, for example, via the control unit 110 (using the beam determination unit 112), use the location information reported by the user device and / or information about the predetermined movement path of the vehicle to determine the relationship between the location of the user device and the edge of the coverage overlap area, such as whether the location of the user device is close to (reached) or away from the edge of the coverage overlap area.

[0098] For example, according to a first predetermined rule for determining the use of a beam, the electronic device 100 can use only the current beam for the user device as the use beam when the user device is located far from the edge of the coverage overlap area. Specifically, the electronic device 100 can determine that the user device is located far from the edge of the coverage overlap area (far from the coverage overlap area) when the user device is located within a predetermined distance from the center of the coverage area of ​​the current beam (the distance can be appropriately set and, for example, proportional to the radius of the coverage area of ​​the beam, etc.), and based on this, directly determine to use only the current beam for the user device as the use beam without performing any beam measurement with the user device. The electronic device 100 can use the transceiver unit 120 to send information about the above-mentioned first predetermined rule to the user device in advance (for example, provided together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in Figure 5), so that the user device can understand that the downlink beam actually used by the base station side is the "current beam" indicated by the previously received information about the current beam (for example, see Figure 5) when the user device is located far from the coverage overlap area.

[0099] In addition, the electronic device 100 may determine to use a beam according to another predetermined rule (such as but not limited to the second, third or fourth predetermined rule described later) when the location of the user equipment is near the coverage overlap area.

[0100] As an example, the electronic device 100 may determine that the position of the user device has reached the edge of the coverage overlap area (near the coverage overlap area) when the position of the user device is within a predetermined distance (the distance may be appropriately set and, for example, may be proportional to the radius of the coverage area of ​​the beam, etc.) from the center of a predicted position on the edge of the coverage area (the predicted position of the user device reaching the edge determined based on the predetermined movement path of the vehicle and the position of the edge of the coverage overlap area, such as the predicted entry position P1 and the predicted exit position P2 shown in FIG. 4 ). Optionally, when the electronic device 100 provides the user device with information about the edge of the coverage overlap area and the information indicates the predicted position of the user device reaching the edge, the user device may, when necessary, determine whether it has reached the edge of the coverage overlap area (near the coverage overlap area) according to similar criteria, and send an edge arrival report to the electronic device 100 when it reaches the corresponding entry side edge and / or exit side edge, so that the electronic device 100 knows that the user device has reached the corresponding edge (near the coverage overlap area).

[0101] For the situation where the user equipment is located near the coverage overlap area (for example, approaching or entering the coverage overlap area, within the coverage overlap area, leaving the coverage overlap area, etc.), the electronic device can use the control unit 110 (using the beam determination unit 112) to determine the use beam according to one or more predetermined rules for using the beam (for example, but not limited to the second, third or fourth predetermined rules described later).

[0102] Example of using beam determination based in part on beam measurements near coverage overlap areas

[0103] In this example, the electronic device 100 may determine to perform beam measurement based on the position of the user equipment reaching the edge of the coverage overlap area (eg, entering the side edge), and determine to use the beam based on the result of the beam measurement.

[0104] More specifically, the electronic device 100 may not perform beam measurement with the user device before the position of the user device reaches the entry side edge of the coverage overlap area, and use the control unit 110 (using the beam determination unit 112) to perform beam measurement of the next beam with the user device after the position of the user device reaches the entry side edge, use the transceiver unit 120 to receive the result of the beam measurement from the user device, and use the control unit 110 (using the beam determination unit 112) to determine one or both of the current beam and the next beam to use based on the result, and use the transceiver unit 120 to send data to the user device using the determined beam.

[0105] Figures 8 and 9 schematically illustrate two example information interactions between the gNB and the UE related to the above-mentioned example processing using beam determination, wherein the second predetermined rule and the third predetermined rule for using beam determination are respectively adopted, and the gNB sends information about the corresponding predetermined rules to the UE in advance (for example, provided together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in Figure 5).

[0106] As shown in Figures 8 and 9, a gNB having the functions of the electronic device 100 can determine that the position of the user equipment has reached the entry side edge of the coverage overlap area based on the position information reported by the user equipment UE (for example, determining that the UE is close to the predicted entry position P1 shown in Figure 4), or know that the position of the user equipment has reached the entry side edge based on the edge arrival report reported by the user equipment, and then perform beam measurement of the next beam with the UE. This measurement can be controlled by the gNB (for example, after generating and sending an optional measurement notification to the UE to indicate the time-frequency resources and beam direction of the next beam) to continuously transmit (for example, continuously transmit by a satellite controlled by the gNB) such as the next beam B shown in Figure 4. N , the UE continuously measures the beam quality of the next beam (for example, the UE receives and measures the downlink beam based on the time-frequency resources and beam direction indicated by the measurement notification), which will not be repeated here.

[0107] According to the second predetermined rule determined by using the beam, the base station side determines to use both the current beam and the next beam when the result of the beam measurement of the next beam is higher than the first threshold for a first period of time after the position of the user equipment reaches the entry side edge of the coverage overlap area.

[0108] As shown in FIG8, when measuring the next beam (for example, the next beam B shown in FIG4), N ), during the beam measurement of the next beam (e.g., the next beam B shown in FIG4 ), the user equipment UE may generate and send a first measurement result report to the gNB when the beam measurement result of the next beam is higher than the first threshold for a first period of time. In other words, the gNB having the functions of the electronic device 100 may use the transceiver unit 120 to receive the measurement result report of the user equipment UE in the next beam (e.g., the next beam B shown in FIG4 ). N ) is higher than a first threshold for a first period of time. Furthermore, the gNB having the functionality of electronic device 100 may use control unit 110 (beam determination unit 112) to determine, based on the first measurement report, whether to use both the current beam and the next beam, and may use transceiver unit 120 to transmit data to user equipment (UE) using both the current beam and the next beam. Accordingly, the UE may receive data transmitted from the gNB using both the current beam and the next beam.

[0109] As shown in Figure 8, after the UE reaches the edge of the coverage overlap area and the beam quality of the next beam remains good for a period of time, the UE is considered to have entered the coverage overlap area and the beam quality of the next beam is acceptable. The gNB then uses both beams for downlink data transmission, which improves transmission quality in the coverage overlap area (for example, using only the current beam or only the next beam may result in poor transmission quality). Alternatively, if the UE enters the coverage overlap area but the beam quality of the next beam does not remain good, the gNB continues to use only the current beam for downlink data transmission. This process avoids continuous measurement of the current beam.

[0110] In addition, according to the third predetermined rule determined by using the beam, the base station side determines to use only the next beam when the result of the beam measurement of the next beam is higher than the second threshold for a second period of time after the position of the user equipment reaches the entry side edge of the coverage overlap area.

[0111] As shown in FIG9 , when measuring the next beam (for example, the next beam B shown in FIG4 ), N ), the user equipment UE may also send a second measurement result report to the gNB if the beam measurement result of the next beam is higher than the second threshold for a second period of time. In other words, the gNB having the functions of the electronic device 100 may use the transceiver unit 120 to receive the measurement result report of the user equipment UE in the next beam (for example, the next beam B shown in FIG4 ). N ) is higher than the second threshold for a second period of time. Furthermore, the gNB having the functions of the electronic device 100 can use the control unit 110 (using the beam determination unit 112) to determine to use only the next beam based on the second measurement result report, and can use the transceiver unit 120 to send data to the user equipment UE using only the next beam. Accordingly, the UE can receive data sent using only the next beam from the gNB. Preferably, the second threshold is higher than the first threshold and / or the second period of time is longer than the first period of time. The example interaction process shown in Figure 9 can be performed in parallel with the example interaction process shown in Figure 8, or after the example interaction process shown in Figure 8 is completed (that is, the second and third predetermined rules can be applied simultaneously or successively), and this is not limited by the present disclosure.

[0112] As shown in Figure 9, after the UE reaches the edge of the coverage overlap area, if the beam quality of the next beam remains good for a long period or remains excellent for a period of time, the UE is considered to have passed the coverage overlap area and entered the coverage area of ​​the next beam. The gNB then uses only the next beam for downlink data transmission. Alternatively, if the UE enters the coverage overlap area but the beam quality of the next beam fails to remain good for a long period or remain excellent for a period of time, the gNB continues to use only the currently used beam (the current beam, or both the current beam and the next beam) for downlink data transmission. This process avoids continuous measurement of the current beam.

[0113] Example of using beam determination to avoid beam measurements near coverage overlap areas

[0114] In this example, the electronic device 100 may directly determine to use a beam without performing beam measurement based on the position of the user equipment reaching the edge of the coverage overlap area.

[0115] More specifically, according to the fourth predetermined rule determined by using beams, the base station side determines to use both the current beam and the next beam when the position of the user equipment reaches the entry side edge of the coverage overlap area, and determines to use the next beam when the position of the user equipment reaches the exit side edge. The electronic device 100 may not perform beam measurement with the user equipment before the position of the user equipment reaches the entry side edge of the coverage overlap area, and use the control unit 110 (using the beam determination unit 112) to determine to use both the current beam and the next beam when the position of the user equipment reaches the entry side edge, and then use the transceiver unit 120 to send data to the user equipment using both the current beam and the next beam, use the control unit 110 (using the beam determination unit 112) to determine to use the next beam when the position of the user equipment reaches the exit side edge, and then use the transceiver unit 120 to send data to the user equipment using only the next beam.

[0116] Figure 10 schematically illustrates an example information exchange between the gNB and the UE related to the above-mentioned example processing using beam determination, wherein a fourth predetermined rule for using beam determination is adopted and the gNB sends information about the predetermined rule to the UE in advance (for example, together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in Figure 5).

[0117] As shown in FIG10 , a gNB having the functionality of electronic device 100 can determine, based on location information reported by a user equipment (UE), whether the user equipment's location has reached the entry-side edge or the exit-side edge of the coverage overlap area (e.g., determining that the UE is near predicted entry position P1 or predicted exit position P2 shown in FIG4 ), or can determine, based on an edge arrival report reported by the user equipment, whether the user equipment's location has reached the entry-side edge or the exit-side edge. According to a fourth predetermined rule for beam determination, the gNB can determine to transmit data to the user equipment using a corresponding beam based solely on the user equipment's location reaching the corresponding edge, without performing any beam measurements.

[0118] As shown in Figure 10, after the UE reaches the entry edge of the coverage overlap area but before reaching the exit edge, the gNB uses both the current beam and the next beam for downlink data transmission. This helps improve transmission quality in the coverage overlap area (for example, using only the current beam or only the next beam may result in poor transmission quality). Furthermore, after the UE reaches the exit edge of the coverage overlap area, it is considered to have passed through the coverage overlap area and entered the coverage area of ​​the next beam, and the gNB uses only the next beam for downlink data transmission. In this way, beam measurement is avoided throughout this example, and beam switching is implemented based solely on geographic location, thereby reducing the energy consumption and signaling interaction associated with beam measurement.

[0119] In the examples of Figures 8, 9 or 10 above, the gNB having the functions of the electronic device 100 uses the transceiver unit 120 to send information about the second, third or fourth predetermined rule to the user equipment UE in advance (for example, provided together with the information about the current beam, the information about the next beam and the information about the edge of the coverage overlapping area in Figure 5), so that the UE can understand the downlink beam actually used on the base station side according to the corresponding rules without the need for real-time notification from the base station.

[0120] For example, in the examples of FIG8 or FIG9 , the UE can, based on the second or third predetermined rule, simultaneously learn that the downlink beam actually used by the base station side is the "current beam" and "next beam" indicated by the previously received information about the current beam and the information about the next beam, or the "next beam" indicated by the previously received information about the next beam, when generating the corresponding first or second measurement result report. In the example of FIG10 , the UE can, based on the UE's location, learn the actually used beam based on the fourth predetermined rule.

[0121] In addition, alternatively or optionally, in the examples of Figures 8, 9 or 10 above, although not shown in the figures, the gNB having the functions of the electronic device 100 can use the transceiver unit 120 to send a beam indication for the actual used beam to the UE again before using the changed beam for data transmission to let the UE know the actual used beam.

[0122] In addition, in the example of FIG. 9 or FIG. 10 (the third or fourth predetermined rule), when the gNB having the function of the electronic device 100 determines to use only the next beam for downlink data transmission, it is actually considered that the UE has entered the coverage area of ​​the next beam and the beam switching has been achieved, so the next beam B can be used. N Set as the new current beam B C . At this time, optionally, the electronic device 100 can use its control unit 110 (beam area determination unit 111) to determine the UE's position, the processing of the current beam and the next beam, and the processing of determining the edge of the coverage overlapping area again in a manner roughly similar to the manner described previously. Optionally, at this time, the UE's position can be determined similarly to the manner described previously based on the position information reported by the UE and / or the information of the predetermined moving path of the vehicle where the UE is located, or directly determined as a predicted position on the edge of the departure side (such as the predicted departure position P2 shown in Figure 4), and the UE's current beam can be directly determined based on the beam switching (the previous next beam B N Set as the new current beam B C ), the next beam and the edge of the coverage overlap area can be determined similarly in the manner described above. Although not shown in Figures 9 or 10, the electronic device 100 can optionally use its transceiver unit 120 to provide the above-determined information to the user equipment UE for subsequent use, which will not be further described here.

[0123] The above describes the electronic device 100 (on the base station side) according to the first embodiment of the present disclosure, which makes it possible to use the relationship between the position of the user equipment and the beam overlapping area to use an appropriate downlink beam for data transmission, which is conducive to reducing dependence on beam measurement.

[0124] In the above description of the electronic device 100 on the base station side according to the first embodiment of the present disclosure, in addition to the electronic device 100 on the base station side, the user equipment UE served by the electronic device 100 and other devices that provide the electronic device 100 with the scheduled path information of the vehicle, such as an information processing device such as a server set in the core network or cloud service platform, are also described. In other words, according to the embodiment of the present disclosure, the inventors have proposed an electronic device and an information processing device on the user side in addition to the electronic device on the base station side. The following will be based on the description of the electronic device on the base station side according to the first embodiment of the present disclosure, and will give a description of the electronic device on the user side according to the second embodiment of the present disclosure and the information processing device according to the third embodiment of the present disclosure, and will omit unnecessary details.

[0125] <3. Configuration Example of Electronic Device of Second Embodiment>

[0126] FIG11 is a block diagram showing a configuration example of a user-side electronic device according to a second embodiment of the present disclosure. The electronic device can be used for a user equipment UE (e.g., a UE on an airplane in FIG1A or FIG1B ) served by the base station-side device described in the base station-side device section of the first embodiment.

[0127] As shown in Figure 11, the electronic device 200 may include a transceiver unit 210 and optionally a location information generating unit 220 and a measuring unit 230. The transceiver unit 210, for example, transmits information to and / or receives information from devices other than the electronic device 200. In addition, although not shown in the figure, the electronic device 200 may also include a control unit for controlling its overall operation / general operation and a storage unit for storage functions.

[0128] Here, each unit of the electronic device 200 may be included in a processing circuit. It should be noted that the electronic device 200 may include either one processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0129] According to this embodiment, the transceiver unit 210 may receive data from a network-side device, the data being sent using one or both of the current beam and the next beam based at least in part on the relationship between the location of the user equipment and the coverage overlap area of ​​the current beam and the next beam for the user equipment. The network-side device may be, for example, a base station-side device (e.g., the base station gNB shown in FIG1A or the non-transparent satellite (with base station function) LEO-1 or LEO-2 shown in FIG1B ). The coverage overlap area may have edges, including an entry-side edge where the user equipment enters the area and an exit-side edge where the user equipment leaves the area. In addition, optionally, the transceiver unit 210 may also receive from the network-side device a predetermined rule for determining the use of the beam, such as, but not limited to, one or more of the first to fourth predetermined rules previously described in the first embodiment.

[0130] The optional location information generation unit 220 can, for example, utilize various positioning functions such as a Global Positioning System (GPS) module to continuously monitor the location of the user equipment and generate location information of the user equipment, which includes, for example, the user equipment's geographic location, (optional) altitude, time (the measurement time of obtaining the geographic location / altitude), etc. The location information generation unit 220 can utilize the transceiver unit 210 to report the generated location information to the network side device (e.g., in real time, periodically, at a predetermined location, or when other predetermined conditions are met) for the network side device to determine the location of the user equipment.

[0131] In a preferred example, the user device may be on a vehicle with a predetermined movement path. In this case, the network-side device may, for example, obtain information about the predetermined movement path of the vehicle in advance using various appropriate methods, and may determine the location of the user device based at least in part on the information about the predetermined movement path.

[0132] As mentioned above, the network side device (base station side device) can determine the current beam and the next beam (for example, the current beam B shown in FIG4 ) for the user equipment based on the location of the user equipment (the location of the user equipment determined according to the location information reported by the user equipment or the information about the predetermined movement path of the vehicle) and the coverage range of the downlink beam controlled by it. C and the next beam B N ), and further determine the coverage overlap area between the two (the edges of the coverage overlap area, such as the entry side edge L1 and / or the exit side edge L2 shown in Figure 4). Optionally, the network-side device can determine the predicted position of the user equipment at the edge (such as P1 and P2 shown in Figure 4) based on the predetermined movement path of the vehicle (such as the route R shown in Figure 4) and the position of the edge of the coverage overlap area (such as L1 and L2 shown in Figure 4).

[0133] The electronic device 200 may obtain one or more of information about the current beam, information about the next beam, and information about the coverage overlap area (edge ​​of the coverage overlap area) from the network-side device, for example, via the transceiver unit 210. As an example, the information about the edge of the coverage overlap area may indicate at least one of the following: the position of the edge of the coverage overlap area (such as the position of the edge L1 and / or L2 shown in FIG4 ); and a predicted position of the user equipment at the edge determined based on the predetermined movement path and the position of the edge (such as the predicted position P1 and / or P2 shown in FIG4 ).

[0134] In addition, optionally, when the network side device obtains information about the predetermined moving path of the vehicle where the user device is located and makes relevant determinations such as the current beam based on the information, the electronic device 200 can also use the transceiver unit 210 to receive information about the predetermined moving path of the vehicle sent by the network side device.

[0135] As an example, the process of the electronic device 200 reporting location information to the network-side device and receiving information about the current beam, information about the next beam, and information about the coverage overlap area (the edge of the coverage overlap area) from the network side (and optionally information about the predetermined movement path of the vehicle, information about the predetermined rule determined using the beam), etc. can be implemented via the example information interaction process previously described with reference to FIG5. In other words, the electronic device 200 for the user equipment can use its transceiver unit 210 and the location information generation unit 220, etc. to implement all the functions or processing of the UE in the example interaction described with reference to FIG5, and no further details are given here.

[0136] The information about the current beam, the next beam and the edge of the coverage overlapping area obtained from the network side device (and optionally the information about the predetermined moving path of the vehicle, and the information about the predetermined rules determined by using the beam) can enable the electronic device 200 to monitor whether it is in the coverage overlapping area (for example, whether it has reached the edge of the coverage overlapping area) using its position information generation unit 220, and can enable the electronic device 200 to know the beam area it is in (and possibly the beam it is using, which will be described later).

[0137] In actual operation of a vehicle, the actual path may deviate from the planned path, such as the example in Figure 6 where the actual flight path R' of an airplane deviates from the planned flight path R. In this case, as shown in Figure 6 , the actual position (P1', P2') of the user equipment at the edge (L1, L2) of the overlapping coverage area may not be consistent with the predicted position (P1, P2) of the user equipment at the edge, as indicated by the information about the edge of the overlapping coverage area obtained from the network-side device.

[0138] In view of this situation, the location information generation unit 220 of the electronic device 200 can be configured to generate and use the transceiver unit 210 to send a deviation report indicating the inconsistency to the network side device when the information about the edge of the coverage overlapping area obtained from the network side device indicates that the user device has reached the predicted position of the edge, and when the actual position of the user device at the edge is inconsistent with the predicted position. As an example, the deviation report can indicate the deviation value between the actual position (P1', P2') and the predicted position (P1, P2), for example, (P1'-P1, P2'-P2). The network side device can refer to the deviation report to correct the position of the user device and the moving path of the vehicle where the user device is located, and use the corrected position and / or path for subsequent processing.

[0139] As an example, the process of the electronic device 200 generating and sending the deviation report to the network-side device can be implemented via the example information interaction process previously described with reference to FIG7. In other words, the electronic device 200 for the user equipment can use its transceiver unit 210 and location information generation unit 220, etc. to implement all functions or processes of the UE in the example interaction described with reference to FIG7, and no further details are given here.

[0140] As described above, the network-side device (base station-side device) may determine the beam to be used based on a predetermined rule for determining the beam to be used, at least in part based on the relationship between the position of the user equipment and the coverage overlap area (the edge of the coverage overlap area), and the electronic device 200 may receive the predetermined rule (for example, together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in FIG5 ) from the network-side device in advance via the transceiver unit 210, such as, but not limited to, one or more of the first to fourth predetermined rules described previously in the first embodiment. The electronic device 200 may perform appropriate processing based on the corresponding beam determination rule received.

[0141] For example, in the case where the location of the user equipment is far away from the coverage overlap area, according to the first predetermined rule for using the beam (only using the current beam for the user equipment as the used beam when the location of the user equipment is far away from the edge of the coverage overlap area), the network side device can, when it is determined that the location of the user equipment is far away from the edge of the coverage overlap area (far away from the coverage overlap area), only use the current beam for the user equipment as the used beam without performing any beam measurement with the user equipment.

[0142] Accordingly, when the first predetermined rule is received (for example, together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in FIG5 ), the electronic device 200 on the user side can, for example, monitor its own position via the position information generation unit 220, and when it is determined that the position of the user device is away from the edge of the coverage overlap area (away from the coverage overlap area), it knows that the downlink beam actually used is the "current beam" indicated by the information about the current beam received from the network side device (for example, see FIG5 ). For example, when the position of the user device is within a predetermined distance (the distance is, for example, half the radius of the coverage area of ​​the current beam or less) from the center of the coverage area of ​​the current beam, the position information generation unit 220 can determine that the position of the user device is away from the edge of the coverage overlap area (away from the coverage overlap area), and accordingly know that the actually used beam is the "current beam" indicated by the information about the current beam.

[0143] In addition, for the situation where the position of the user equipment is near the coverage overlapping area, for example, according to the second or third predetermined rule determined by using the beam, the network side device can determine to perform beam measurement based on the position of the user equipment reaching the edge of the coverage overlapping area (for example, entering the side edge), and determine to use the beam in combination with the result of the beam measurement; for example, according to the fourth predetermined rule determined by using the beam, the network side device can determine to use the beam only based on the position of the user equipment reaching the edge of the coverage overlapping area without performing beam measurement.

[0144] Accordingly, the user-side electronic device 200 that receives the second, third or fourth predetermined rule can, for example, monitor the location of the user device via the location information generation unit 220, and determine whether the location of the user device reaches the edge of the coverage overlap area, and then use the corresponding unit to perform corresponding processing according to the corresponding predetermined rule (and optional further instructions from the network side).

[0145] As an example, optionally, when the network side device provides information about the edge of the coverage overlap area to the user device and the information indicates the predicted position of the user device reaching the edge, the location information generation unit 220 of the electronic device 200, for example, which receives the second, third or fourth predetermined rule, can be configured to: determine whether the user device has reached the corresponding edge of the coverage overlap area (near the coverage overlap area), and generate and use the transceiver unit 210 to send an edge arrival report to the network side device when reaching the corresponding entry side edge and / or exit side edge, so that the network side device knows that the user device has reached the corresponding edge (near the coverage overlap area). For example, the location information generation unit 220 can determine that the position of the user device has reached the edge of the coverage overlap area (near the coverage overlap area) when the position of the user device is within a predetermined distance (the distance is, for example, one quarter of the radius of the coverage area of ​​the current beam or less) from the center of the predicted position on the edge of the coverage area (such as position P1 or P2 shown in Figure 4).

[0146] In addition, in one example, when the network-side device uses the second or third predetermined rule and determines to perform beam measurement based on the position of the user equipment reaching the edge of the coverage overlap area (e.g., entering the side edge), the optional measurement unit 230 of the electronic device 200 that receives the second or third predetermined rule can determine that the position of the user equipment reaches the edge of the coverage overlap area based on the location information generation unit 220 and / or based on the measurement notification received from the network-side device, and perform measurement of the corresponding downlink beam (i.e., the "next beam" indicated by the information about the next beam previously received from the network side as shown in FIG5). The measurement unit 230 can also generate a beam measurement report based on the result of the beam measurement when appropriate and send the beam measurement report to the network-side device using the transceiver unit 210 for the network-side device to determine the beam to be used.

[0147] More specifically, in this example, the measurement unit 230 of the electronic device 200 that receives the second or third predetermined rule determined using the beam can be configured to: not perform beam measurement before the position of the user equipment reaches the edge of the entry side; and perform beam measurement of the next beam with the network side device after the position of the user equipment reaches the edge of the entry side, and generate and report the result of the beam measurement to the network side device using the transceiver unit 210, so that the network side device can use one or both of the current beam and the next beam to send data to the user equipment based on the result. As an example, the measurement can be controlled by the network side device (for example, after sending an optional measurement notification to the electronic device 200) to continuously send the next beam B shown in Figure 4 N, the measurement unit 230 continuously measures the beam quality of the next beam (the measurement unit 230 can, for example, receive and measure the downlink beam based on the time-frequency resources and beam direction indicated by the measurement notification), which will not be repeated here.

[0148] For example, when the electronic device 200 receives a second predetermined rule for using beam determination (using both the current beam and the next beam when the result of beam measurement of the next beam is higher than the first threshold for a first period of time after the position of the user equipment reaches the entry side edge of the coverage overlap area), when measuring the next beam (for example, the next beam B shown in FIG. 4 ), the current beam and the next beam are both used. N ), during the beam measurement of the next beam, the measurement unit 230 of the electronic device 200 can further generate and use the transceiver unit 210 to send a first measurement result report to the network side device when the result of the beam measurement of the next beam is higher than the first threshold for a first period of time, and the transceiver unit 210 of the electronic device 200 can receive data sent using both the current beam and the next beam from the network side device.

[0149] Alternatively or additionally, for example, when the electronic device 200 receives a third predetermined rule determined using a beam (only using the next beam when the beam measurement result of the next beam is higher than a second threshold for a second period of time after the position of the user equipment reaches the entry-side edge of the coverage overlap area), the measurement unit 230 of the electronic device 200 may further generate and use the transceiver unit 210 to send a second measurement result report to the network-side device when the beam measurement result of the next beam is higher than the second threshold for a second period of time, and the transceiver unit 210 of the electronic device 200 may receive data sent only using the next beam from the network-side device. Preferably, the second threshold is higher than the first threshold and / or the second period of time is longer than the first period of time.

[0150] As an example, the process in which the electronic device 200 receives data sent by the network-side device using different beams based on the relationship between the location of the user equipment and the edge of the coverage overlap area and the result of the beam measurement can be implemented via the example information interaction process previously described with reference to Figures 8 and / or 9. In other words, the electronic device 200 for the user equipment can use its transceiver unit 210, location information generation unit 220, measurement unit 230, etc. to implement all the functions or processing of the UE in the example interaction described with reference to Figures 8 and / or 9, and no further details are given here.

[0151] In another example, for example, according to a fourth predetermined rule determined by using a beam (using both the current beam and the next beam when the position of the user equipment reaches the entry side edge of the coverage overlap area, and using the next beam when the position of the user equipment reaches the exit side edge), the network side device can determine to use a beam only based on the position of the user equipment reaching the edge of the coverage overlap area without performing beam measurement.

[0152] Accordingly, in this example, upon receiving the fourth predetermined rule determined using a beam, the electronic device 200 can, without performing beam measurement, receive data sent using both the current beam and the next beam from the network side device, for example, using the transceiver unit 210, after the position of the user device reaches the entry side edge; and / or receive data sent only using the next beam from the network side device, for example, using the transceiver unit 210, after the position of the user device reaches the exit side edge.

[0153] As an example, the process in which the electronic device 200 receives data sent by the network-side device using different beams based solely on the relationship between the location of the user equipment and the edge of the coverage overlap area can be implemented via the example information interaction process previously described with reference to FIG10. In other words, the electronic device 200 for the user equipment can utilize its transceiver unit 210, location information generation unit 220, measurement unit 230, etc. to implement all functions or processes of the UE in the example interaction described with reference to FIG10, and no further details are given here.

[0154] In the above example where the network-side device uses the second, third, or fourth predetermined rule to determine the beam to be used and the electronic device 200 receives information about the second, third, or fourth predetermined rule sent by the network-side device (for example, provided together with the information about the current beam, the information about the next beam, and the information about the edge of the coverage overlap area in FIG5 ), the electronic device 200 can understand the downlink beam actually used by the base station side according to the corresponding rule without the need for real-time notification from the base station. The electronic device 200 knows the actual downlink beam, which is beneficial for its transceiver unit 210 to use the corresponding beam to receive downlink data.

[0155] For example, in scenarios where the second or third predetermined rule is used, electronic device 200, at the same time as measurement unit 230 generates the corresponding first or second measurement result report, understands that the downlink beam actually used by the base station side is the "current beam" and "next beam" indicated by the previously received information about the current beam and the information about the next beam, or the "next beam" indicated by the previously received information about the next beam. In scenarios where the fourth predetermined rule is used, electronic device 200 can understand the actually used beam based on the location of the user equipment monitored by location information generation unit 220.

[0156] In addition, alternatively or optionally, the electronic device 200 can receive a beam indication for the actual beam used, which is sent again by the network side device before it uses the changed beam for data transmission, so as to know the actual beam used, which will not be repeated here.

[0157] In addition, in the examples of the third or fourth predetermined rules above, when only the next beam is used for downlink data transmission, it is considered that the user equipment has entered the coverage area of ​​the next beam and beam switching has been achieved, so the next beam can be set as the new current beam. At this time, optionally, the network-side device can again determine the position of the user equipment, the processing of the current beam and the next beam, and the processing of determining the edge of the coverage overlapping area in a manner roughly similar to that described previously. Optionally, the network-side device can determine the position of the user equipment in a manner similar to that described previously based on the position information reported by the user equipment and / or the information of the predetermined moving path of the vehicle where the user equipment is located, or directly determine it as a predicted position on the edge of the departure side (such as the predicted departure position P2 shown in Figure 4), and can directly determine the current beam of the user equipment based on the beam switching (such as the previous next beam B shown in Figure 4). N Set as the new current beam B C ), and the next beam of the user equipment and the edge of the coverage overlap area can be determined similarly in the manner described above. Optionally, the electronic device 200 can use its transceiver unit 210 to receive various information determined in the above manner from the network side device for subsequent use, which will not be repeated here.

[0158] The above describes the user-side electronic device 200 according to an embodiment of the present disclosure. Through its interaction with the network-side device (base station-side device), it is possible to use the relationship between the position of the user device and the beam overlapping area to use an appropriate downlink beam for data transmission, which is conducive to reducing dependence on beam measurement.

[0159] <4. Configuration Example of Information Processing Apparatus of Third Embodiment>

[0160] Figure 12 is a block diagram illustrating a configuration example of an information processing device according to a third embodiment of the present disclosure. This information processing device can be used to provide the base station-side device of the first embodiment with information about the predetermined movement path of the vehicle in which the user equipment is located, and can be, for example, a server provided in a core network or a cloud service platform.

[0161] As shown in Figure 12, information processing device 300 may include a transceiver unit 310 and an optional control unit 320. Transceiver unit 310, for example, transmits information to and / or receives information from devices outside information processing device 300. In addition, although not shown in the figure, information processing device 300 may also include a storage unit.

[0162] Here, each unit of information processing device 300 may be included in a processing circuit. It should be noted that information processing device 300 may include either a single processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical or logical entities, and units with different designations may be implemented by the same physical entity.

[0163] According to this embodiment, the transceiver unit 310 can send information about the predetermined moving path of a vehicle to an electronic device used for wireless communication (for example, the electronic device 100 on the base station side according to the first embodiment), so that the electronic device can determine, at least in part based on the information, the relationship between the position of a user device (for example, the electronic device 200 on the user side according to the second embodiment) on the vehicle and the edge of the coverage overlapping area of ​​the current beam and the next beam for the user device to send data to the user device using one or both of the current beam and the next beam.

[0164] The information about the planned movement path of the vehicle may include, for example, information indicating the following: an identifier (ID) of the vehicle and / or a number of the movement path (flight number / train number, etc.), a geographical location (and optionally an altitude) on the movement path, a time associated with the geographical location (and optionally an altitude) on the movement path, etc. Optionally, the information may also include information indicating a movement direction (associated with the geographical location (and optionally an altitude) and time on the movement path).

[0165] The information processing device 300 can obtain information about the vehicle's scheduled movement path, for example, via various appropriate means. For example, the information processing device 300 can obtain information about the vehicle's scheduled movement path from the vehicle's operator (an airline, railway company, trucking company, shipping company, etc.) or other relevant parties regularly or periodically via the transceiver unit 310 under the control of the control unit 320, and can obtain updated information about the vehicle's movement path in real time.

[0166] The information processing device 300 can provide information about the vehicle's planned movement path to the electronic device on the base station side in various appropriate ways. For example, the information processing device 300 can periodically and regularly (e.g., a predetermined time before the vehicle enters the coverage area of ​​the electronic device on the base station side) and only when the movement path is updated, via the transceiver unit 310 under the control of the control unit 320.

[0167] The above describes the electronic devices and information processing devices according to the first to third embodiments of the present disclosure. In a variant of the present disclosure, a proxy device or a relay node (such as an IAB node) or other devices may be provided on the vehicle, and the device may uniformly obtain information about the predetermined movement path of the vehicle from the information processing device of the third embodiment (such as a server of a core network or a cloud service platform). Optionally, the device may forward the information about the predetermined movement path of the vehicle to all user devices on the vehicle (such as those having some or all of the functions of the electronic device of the second embodiment). In addition, instead of the user device on the vehicle generating and sending the location information of the user device to the base station side device (such as those having some or all of the functions of the electronic device of the third embodiment), the device may generate and send the location information of the vehicle to the base station side device for use by the base station side device. When appropriate, the device may also forward or relay other data and / or information between the base station side device and the user device on the vehicle, which will not be described in detail here.

[0168] <5. Method Example>

[0169] Corresponding to the above-mentioned device embodiments, the present disclosure provides the following method embodiments.

[0170] (Method Example of the First Embodiment)

[0171] FIG13 is a flowchart showing a procedure example of the method for wireless communication on the base station side according to the first embodiment.

[0172] As shown in FIG13 , in step S11, data is transmitted to the user equipment using one or both of the current beam and the next beam based at least in part on a relationship between the location of the user equipment and a coverage overlap region between the current beam and the next beam for the user equipment. The coverage overlap region may, for example, have an entry-side edge where the user equipment enters the region and an exit-side edge where the user equipment exits the region.

[0173] Although not shown in the figure, step S11 may, for example, include the following processing: not performing beam measurement with the user equipment before the position of the user equipment reaches the entry side edge; and performing beam measurement of the next beam with the user equipment after the position of the user equipment reaches the entry side edge, receiving the result of the beam measurement from the user equipment, and using one or both of the current beam and the next beam to send data to the user equipment based on the result.

[0174] In one example, step S11 may further include: receiving a first measurement result report sent by the user equipment when the result of beam measurement of the next beam is higher than a first threshold for a first period of time, and sending data to the user equipment using both the current beam and the next beam according to the first measurement result report. Additionally or alternatively, step S11 may further include: receiving a second measurement result report sent by the user equipment when the result of beam measurement of the next beam is higher than a second threshold for a second period of time, and sending data to the user equipment using only the next beam according to the second measurement result report.

[0175] In another example, step S11 may further include performing the following processing without performing beam measurement with the user equipment: when the position of the user equipment reaches the entry side edge, using both the current beam and the next beam to send data to the user equipment; and / or when the position of the user equipment reaches the exit side edge, using only the next beam to send data to the user equipment.

[0176] In a preferred example, the user device is on a vehicle with a predetermined movement path. In this case, although not shown in the figure, step S11 may include, for example, the following processes: obtaining information about the predetermined movement path from another device; and determining the user device's location, current beam, and next beam based at least in part on the information about the predetermined movement path.

[0177] Optionally, step S11 may further include providing the user equipment with information about the current beam, information about the next beam, and information about an edge of the coverage overlap area. For example, the information about the edge of the coverage overlap area may indicate at least one of: a location of the edge; and a predicted location of the user equipment at the edge determined based on the predetermined movement path and the location of the edge.

[0178] Optionally, when the information about the edge of the coverage overlap area indicates the predicted position, step S11 may further include receiving a deviation report sent by the user equipment when the actual position of the user equipment at the edge is inconsistent with the predicted position, indicating the inconsistency. Optionally, step S11 may further include determining the position of the user equipment, the current beam, and the next beam with reference to the deviation report.

[0179] As an example, the example method shown in FIG13 can be executed by a base station in a non-ground network, and in step S11, the current beam and the next beam of the user equipment can be determined based on the ephemeris map of the satellite that transmits the downlink beam and is controlled by the non-ground network base station. In addition, optionally, step S11 can further include: after the user equipment accesses the non-ground network base station, starting a timer; after the timer expires, determining whether the ephemeris map and / or geographic location of the satellite controlled by the non-ground network base station is updated; if the ephemeris map and / or geographic location are updated, determining the current beam and the next beam of the user equipment based on the updated ephemeris map and / or geographic location.

[0180] According to an embodiment of the present disclosure, the subject executing the above method may be an electronic device on the base station side according to the first embodiment of the present disclosure, so all the embodiments of the electronic device on the base station side in the foregoing text are applicable here and will not be repeated here.

[0181] (Method Example of the Second Embodiment)

[0182] FIG14 is a flowchart showing a process example of a method for wireless communication on the user side according to the second embodiment.

[0183] As shown in FIG14 , in step S21, data is received from a network-side device. The data is transmitted using one or both of a current beam and a next beam based at least in part on a relationship between a location of a user equipment and a coverage overlap region between the current beam and the next beam for the user equipment. The coverage overlap region may, for example, have an entry-side edge where the user equipment enters the region and an exit-side edge where the user equipment exits the region.

[0184] Although not shown in the figure, step S21 may further include the following processing, for example: no beam measurement is performed before the position of the user equipment reaches the edge of the entry side; and after the position of the user equipment reaches the edge of the entry side, beam measurement of the next beam is performed with the network side device, and the result of the beam measurement is reported to the network side device, so that the network side device can use one or both of the current beam and the next beam to send data to the user equipment according to the result.

[0185] In one example, step S21 may further include: if the beam measurement result of the next beam is higher than a first threshold value for a first period of time, sending a first measurement result report to the network-side device, and receiving data sent using both the current beam and the next beam from the network-side device. Additionally or alternatively, step S21 may further include: if the beam measurement result of the next beam is higher than a second threshold value for a second period of time, sending a second measurement result report to the network-side device, and receiving data sent using only the next beam from the network-side device.

[0186] In another example, step S21 may further include performing the following processing without performing beam measurement with the user equipment: after the position of the user equipment reaches the entry side edge, receiving data sent using both the current beam and the next beam from the network side device; and / or after the position of the user equipment reaches the exit side edge, receiving data sent using only the next beam from the network side device.

[0187] In a preferred example, the user device is on a vehicle with a predetermined movement path. In this case, although not shown in the figure, step S21 may include, for example, the following processing: obtaining information about the current beam, information about the next beam, and information about the edge of the overlapping coverage area from the network-side device. For example, the information about the edge of the overlapping coverage area may indicate at least one of the following: the location of the edge; and a predicted location of the user device at the edge, determined based on the predetermined movement path and the location of the edge.

[0188] Optionally, when the information about the edge of the coverage overlapping area indicates the predicted position, step S21 may further include: when the actual position of the user equipment reaching the edge is inconsistent with the predicted position, sending a deviation report indicating the inconsistency to the network side device.

[0189] According to an embodiment of the present disclosure, the subject executing the above method may be an electronic device on the user side according to the second embodiment of the present disclosure, so all the embodiments of the electronic device on the user side in the foregoing text are applicable here and will not be repeated here.

[0190] (Method Example of the Third Embodiment)

[0191] FIG. 15 is a flowchart illustrating a procedure example of an information processing method according to the third embodiment of the present disclosure.

[0192] As shown in Figure 15, in step S31, information about the predetermined moving path of a vehicle is sent to an electronic device used for wireless communication, so that the electronic device can determine, at least in part based on the information, the relationship between the position of a user device on the vehicle and the edge of the coverage overlapping area of ​​the current beam and the next beam for the user device to send data to the user device using one or both of the current beam and the next beam.

[0193] According to an embodiment of the present disclosure, the subject executing the above method may be an information processing device according to the third embodiment of the present disclosure, so all the embodiments of the electronic device on the user side in the foregoing text are applicable here and will not be repeated here.

When the electronic device is implemented on the base station side, the electronic device can be implemented as any type of base station device, such as a macro eNB and a small eNB, and can also be implemented as any type of gNB (a base station in a 5G system). A small eNB can be an eNB that covers a cell smaller than a macro cell, such as a pico eNB, a micro eNB, and a home (femto) eNB. Alternatively, the base station device can be implemented as any other type of base station, such as a NodeB and a base transceiver station (BTS). The base station may include: a main body (also referred to as a base station device) configured to control wireless communications; and one or more remote radio heads (RRHs) arranged in a place different from the main body.

[0200] [Application examples regarding control entities]

[0201] 16 is a block diagram illustrating an example of a schematic configuration of a server 1700 to which the technology of the present disclosure can be applied. The server 1700 includes a processor 1701 , a memory 1702 , a storage device 1703 , a network interface 1704 , and a bus 1706 .

[0202] The processor 1701 may be, for example, a central processing unit (CPU) or a digital signal processor (DSP), and controls the functions of the server 1700. The memory 1702 includes a random access memory (RAM) and a read-only memory (ROM), and stores data and programs executed by the processor 1701. The storage device 1703 may include a storage medium such as a semiconductor memory and a hard disk.

[0203] The network interface 1704 is a wired communication interface for connecting the server 1700 to the wired communication network 1705. The wired communication network 1705 may be a core network such as an evolved packet core (EPC) or a packet data network (PDN) such as the Internet.

[0204] The bus 1706 connects the processor 1701, the memory 1702, the storage device 1703, and the network interface 1704 to each other. The bus 1706 may include two or more buses each having a different speed (such as a high-speed bus and a low-speed bus).

[0205] In the server 1700 shown in FIG16 , the control unit in the information processing device 300 of the third embodiment described above with reference to FIG12 can be implemented by a processor 1701. For example, the processor 1701 can perform the functions of the control unit by executing instructions stored in the memory 1702 or the storage device 1703. In addition, the transceiver unit in the information processing device 300 can be implemented via a network interface 1704 or the like.

[0206] [Application examples for base stations]

[0207] (First application example)

[0208] 17 is a block diagram showing a first example of a schematic configuration of an eNB to which the technology of the present disclosure can be applied. The eNB 1800 includes one or more antennas 1810 and a base station device 1820. The base station device 1820 and each antenna 1810 can be connected to each other via an RF cable.

[0209] Each of the antennas 1810 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input, multiple-output (MIMO) antenna) and is used for base station device 1820 to transmit and receive wireless signals. As shown in FIG17 , eNB 1800 may include multiple antennas 1810. For example, multiple antennas 1810 may be compatible with multiple frequency bands used by eNB 1800. Although FIG17 shows an example in which eNB 1800 includes multiple antennas 1810, eNB 1800 may also include a single antenna 1810.

[0210] The base station device 1820 includes a controller 1821 , a memory 1822 , a network interface 1823 , and a wireless communication interface 1825 .

[0211] The controller 1821 may be, for example, a CPU or a DSP, and operates various functions of the higher layers of the base station device 1820. For example, the controller 1821 generates data packets based on the data in the signal processed by the wireless communication interface 1825, and transmits the generated packets via the network interface 1823. The controller 1821 may bundle data from multiple baseband processors to generate bundled packets, and transmit the generated bundled packets. The controller 1821 may have logic functions for performing the following controls: the control may be radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control may be performed in conjunction with a nearby eNB or core network node. The memory 1822 includes RAM and ROM, and stores programs executed by the controller 1821 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

[0212] The network interface 1823 is a communication interface for connecting the base station device 1820 to the core network 1824. The controller 1821 can communicate with the core network node or another eNB via the network interface 1823. In this case, the eNB 1800 and the core network node or other eNB can be connected to each other through a logical interface (such as an S1 interface and an X2 interface). The network interface 1823 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line.

In place of the controller 1821, the BB processor 1826 may perform some or all of the aforementioned logical functions. The BB processor 1826 may be a memory that stores communication control programs, or a module including a processor configured to execute programs and associated circuitry. Program updates can modify the functionality of the BB processor 1826. This module may be a card or blade inserted into a slot in the base station device 1820. Alternatively, the module may be a chip mounted on the card or blade. Meanwhile, the RF circuit 1827 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 1810 .
