Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a measurement method, an apparatus, a terminal, and a network side device.
Background
Terrestrial networks typically employ cellular networking. The reason cellular networks are widely used is derived from the mathematical conclusion that the circles used, with the same radius of the circular coverage plane, are the least number of circles when the center of the circle is at the center of each regular hexagon of a regular hexagonal grid, i.e. when the center of the circle is at a grid point of a regular triangular grid.
A cellular network widely used is a planar cell, which has good service performance for a conventional ground terminal, but for a special terminal such as an aircraft, there is too much complexity in the management of the aircraft service including handover, access and neighbor relation based on the ground network technology, for example, as the aircraft moves, for example, during a take-off or landing process, the aircraft may rapidly experience multiple cells based on the ground network, and frequent handover occurs, which leads to degradation of system performance.
One possible deployment is a combination of networks, such as a terrestrial network, a space-based network (e.g., a drone), or a space-based network (e.g., a satellite), for example, for the cell serving the network. Due to different flight characteristics of the aircraft and different channel models and different propagation characteristics caused by the types of the service base stations, the combined network service terminal has a plurality of problems, for example, different types of networks of the combined network, such as different propagation channels of a ground network, a space-based network and a space-based network, have different propagation delays, and affect the measurement performance of the terminal.

Detailed Description
To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In order to solve the mobility problem caused by the fact that an aircraft terminal rapidly passes through multiple cells (including a vertical dimension, a horizontal dimension, the same type of base station and different types of base stations) in a short time, the embodiment of the invention introduces a stereo cell, wherein the stereo cell refers to a cell formed by one or more base stations or transmitting points or antennas or satellites by using an intelligent antenna technology, multiple stereo cells can form a stereo cell group, and the introduction of the stereo cell affects the mobility of the terminal. The stereo cell may cover a plurality of network devices of one network, or the stereo cell may cover network devices of at least two networks. The above network includes: ground based networks, space based networks (e.g., satellites).
It should be noted that the stereo cell may also be referred to as: in addition, the space-based network device or the space-based network device may move, and the above factors may all affect the measurement, cell reselection, or cell handover of the terminal.
Considering the ground base station, the space base station equipment and the satellite can jointly form 1 stereo cell, and even if three parties synchronously transmit signals, the terminal can receive the reference symbols of the same cell at different times due to different transmission time delays. This situation is contrary to the periodic transmission of the reference symbol (the transmission of the reference symbol at a certain frequency point can be considered to have a fixed period, a fixed duration, and a fixed offset), which may cause confusion of the terminal measurement behavior, and for terminals at different positions, the received signal strength of the three-party network device is different, and the measurement performance cannot be guaranteed.
In view of the above problem, as shown in fig. 1, an embodiment of the present invention provides a measurement method, including at least one of:
and 103, the terminal reports part or all of the measurement results.
As an alternative embodiment, step 101 includes:
a terminal receives first information for a first cell, where the first cell includes a plurality of network devices located at different altitudes and/or longitudes and/or latitudes and/or different geographical locations and/or different speeds.
As an alternative embodiment, the first information includes: measuring the relevant measurement information. The above-mentioned reference symbols may be obtained by measurement information.
As an optional embodiment, the measurement information includes at least one of:
a period of the reference symbol;
a duration of a reference symbol;
an offset value for a reference symbol;
a period of the measurement interval;
the duration of the measurement interval;
measuring an offset value of the interval;
third indication information, the third indication information including at least one of: a pre-configured measurement interval, a network control mini-interval, a concurrent measurement interval.
Wherein the third indication information is used to indicate a type of the measurement interval; the Pre-configured measurement interval may also be described as a Pre-configured measured gap (Pre-MG), which is configured by RRC, activated/deactivated by network indication, or activated/deactivated meeting certain criteria. The network control small interval can also be described as a Network Controlled Small Gap (NCSG), and the measurement time of the measurement interval is short or the terminal is small; concurrent measurement intervals may also be described as con-current measurement gap, i.e., multiple measurement intervals may be configured.
It should be noted that the reference symbols are measurement reference symbols, including a synchronization signal block SSB (also described as SMTC), and/or a channel state information reference signal CSI-RS, and/or a positioning reference signal PRS, etc.
As an alternative embodiment, the method further comprises:
the terminal receives second information, wherein the second information comprises: measuring an association of information with the first node and/or beam; the second information may be delivered by broadcast, or may be delivered by radio resource control RRC (for example, configured in MO). The first node is a first node of a first cell. The terminal can determine the measurement information of the first cell according to the association relation in the first information.
Wherein network nodes operating at different altitudes and/or longitudes and/or dimensions have different identities and the measurement information may be associated with the associated identities. The measurement information may also be associated with a beam identification. Beams of different identities or different identities groups (i.e. the group has a plurality of beams, corresponding to a plurality of beam IDs, the beams of the group all belonging to the same or same type of network device) come from different network nodes.
For example, the second information includes: measuring the incidence relation between the information and the identifier of the first node; for another example, the second information includes: measuring the incidence relation between the information and the beam identifier; for another example, the second information includes: and the incidence relation of the measurement information with the first node identification and the beam identification.

When a cell only sends 1 fixed set or multiple sets of SMTCs (multiple sets of SMTCs means that even if 2 or more sets of SMTCs are sent, the SMTCs are not mapped to network devices in a one-to-one manner), the terminal may be further instructed to receive the time domain offset of a certain network device or network devices based on the current SMTC configuration; the offset information for the SMTC includes offset information for the SMTC for different network devices. The offset information for the SMTC may be different for different network devices (such as network devices at different altitudes and/or longitudes and/or dimensions and/or speeds; or different types of network devices, such as ground networks/base stations, drones, airborne base Stations (ATGs), hot air balloons, satellites, etc.), the offset information including at least one of: period shift, duration shift, start position shift.

The embodiment of the invention introduces the first terminal capability information, and the terminal meeting the first terminal capability information can work in a three-dimensional cell or beam; and the terminal reports whether the network supports the first terminal capability information. For a three-dimensional cell/beam, if the terminal reports and supports the first terminal capability information, the terminal can access the network; the network may prohibit the terminal from accessing if the terminal does not support the first terminal capability information. For the normal cell, if the terminal reports and supports the first terminal capability information, the network can forbid the terminal from accessing. If the normal cell allows the terminal supporting the first terminal capability information to access, the terminal may be preferentially handed over to the stereo cell among a plurality of candidate cells/beams at the time of handover.

Herein, the first cell is also referred to as a stereo cell or a dynamic cell. The first cell comprises a plurality of network devices located at different altitudes and/or latitudes and/or different geographical locations. When the terminal performs cell reselection, if the terminal is an aircraft type terminal, the terminal preferentially reselects a cell/beam with the first identifier. Specifically, embodiment 1: when the cell qualities of a plurality of cells are the same, the terminal preferentially reselects the cell with the first identifier; embodiment 2: and the terminal preferentially reselects the cell with the first identifier to the cell within a certain quality threshold range, such as the cell with the cell quality higher than a certain threshold and/or a plurality of cells with the cell quality within a certain threshold from the cell quality of the cell with the best quality. Embodiment 3: when the beam qualities of a plurality of beams are the same, the terminal preferentially reselects the beam with the first identifier; embodiment 4: a beam within a certain quality threshold range, such as a beam with a beam quality above a certain threshold and/or a plurality of beams within a certain threshold of the beam quality of the beam with the best quality, is preferentially reselected by the terminal to the beam with the first identifier.
The horizontal coverage information includes indication of whether horizontal coverage enhancement is present and/or coverage enhancement levels for the horizontal coverage (which may include N coverage enhancement levels, a first horizontal coverage, a second horizontal coverage, etc., \8230;, an Nth horizontal coverage), and/or horizontal coverage radius information, etc. When the terminal performs cell reselection, if the terminal is an aircraft type terminal and the terminal performs movement in the horizontal dimension, the terminal preferentially reselects a cell or a beam with a horizontal coverage enhancement indication. Further, the terminal may preferentially select a cell or a beam to an appropriate coverage enhancement level from a plurality of cells or beams having horizontal coverage enhancement indications according to its own motion trajectory. Specifically, embodiment 1: when the cell qualities of a plurality of cells are the same, or the cell qualities of the plurality of cells are higher than a certain threshold, or the plurality of cells are within a certain threshold of the cell quality of the cell with the best quality, the terminal preferentially reselects the cell with the horizontal coverage enhancement indication. Further, if there are multiple cells having horizontal coverage enhancement indications but different coverage enhancement levels, the terminal may select a cell corresponding to a suitable coverage enhancement level according to its own requirements. For example, the terminal may perform horizontal movement for a longer period of time, and if there are 2 cells corresponding to 2 horizontal coverage levels, respectively, and the coverage of the first coverage level is smaller than the second coverage level, the terminal may preferentially reselect to the cell corresponding to the second coverage level.
The vertical overlay information includes indication information of whether vertical overlay enhancement is present, and/or overlay level of vertical overlay (which may include N overlay enhancement levels, first vertical overlay, second vertical overlay, etc., \8230;, nth vertical overlay), and/or vertical overlay radius information, etc.; when the terminal performs cell reselection, if the terminal is an aircraft type terminal and the terminal performs movement in a vertical dimension, the terminal preferentially reselects a cell or a beam with a vertical coverage enhancement indication. Further, the terminal may preferentially select a cell or a beam to an appropriate coverage enhancement level from a plurality of cells or beams having vertical coverage enhancement indications according to its own motion trajectory. Specifically, embodiment 1: when the cell qualities of a plurality of cells are the same, or the cell qualities are higher than a certain threshold, or the cell qualities of the cells with the best quality are within a certain threshold, the terminal preferentially reselects the cell with the vertical coverage enhancement indication. Further, if there are multiple cells having vertical coverage enhancement indications but different coverage enhancement levels, the terminal may select a cell corresponding to a suitable coverage enhancement level according to its own requirement. For example, the terminal may also perform vertical movement for a longer period of time, and if 2 cells respectively correspond to 2 vertical coverage levels, and the coverage of the first coverage level is smaller than that of the second coverage level, the terminal may preferentially reselect to the cell corresponding to the second coverage level. Embodiment 2: when the following motion trajectory of the terminal is uncertain, or there are requirements for horizontal movement and vertical movement simultaneously within a certain time, the terminal may preferentially reselect a cell having both horizontal coverage enhancement indication and vertical coverage enhancement indication. Optionally, a suitable cell may be further selected for reselection according to the horizontal coverage enhancement level and the vertical coverage enhancement level.
The speed information comprises indication information indicating whether the cell/beam will move or not, and/or the direction of movement of the cell/beam (horizontal direction, vertical direction, angle information with respect to sea level/ground level), and/or the horizontal speed of movement or speed range of the cell/beam, and/or the vertical speed of movement or speed range of the cell/beam, and/or the speed of movement or speed range along an angle. If the current terminal is in a static state, the terminal detects a cell/beam with better signal quality, but the speed identifier of the cell indicates that the cell is a mobile cell/beam (horizontal movement and vertical movement), and the terminal does not reselect the cell/beam. Or among a plurality of candidate cells/beams, if the terminal itself is in a stationary or low-speed moving state, identified as a moving cell/beam, the cell is reselected with a lower priority. If the terminal is in a moving state, the terminal may preferentially reselect to a cell/beam whose moving direction and/or moving speed is more matched or closer to the terminal.
The frequency priority is that aiming at the terminal of the aircraft type, the priority of the working frequency of the three-dimensional dynamic cell/beam is higher than the working frequency of other types of cells. For a common terminal, the priority of the working frequency of the stereo dynamic cell/beam is lower than that of other types of cells/beams.

Further, the terminal may preferentially select a cell or a beam to an appropriate coverage enhancement level from a plurality of cells or beams having horizontal coverage enhancement indications according to its own motion trajectory. Specifically, embodiment 1: when the cell quality of a plurality of cells is the same, or the cell quality is higher than a certain threshold, or the cell quality is different from the cell quality of the best cell within a certain threshold, the terminal preferentially reselects the cell with the horizontal coverage enhancement indication.

Further, the terminal may preferentially select a cell or a beam to an appropriate coverage enhancement level from a plurality of cells or beams having vertical coverage enhancement indications according to its own motion trajectory. Specifically, embodiment 1: when the cell qualities of a plurality of cells are the same, or the cell qualities are higher than a certain threshold, or the cell qualities of the cells with the best quality are within a certain threshold, the terminal preferentially reselects the cell with the vertical coverage enhancement indication. Further, if there are multiple cells with vertical coverage enhancement indications but with different coverage enhancement levels, the terminal may select a cell corresponding to a suitable coverage enhancement level according to its own requirements. For example, the terminal may also perform vertical movement for a longer period of time, and if 2 cells respectively correspond to 2 vertical coverage levels, and the coverage of the first coverage level is smaller than that of the second coverage level, the terminal may preferentially reselect to the cell corresponding to the second coverage level. Embodiment 2: when the following motion trail of the terminal is uncertain, or the requirements of horizontal movement and vertical movement exist simultaneously within a certain time, the terminal can preferentially reselect a cell with a horizontal coverage enhancement indication and a vertical coverage enhancement indication simultaneously.

If the current terminal is in a static state, the terminal detects a cell/beam with better signal quality, but the speed identifier of the cell indicates that the cell is a mobile cell/beam (horizontal movement and vertical movement), and the terminal does not reselect the cell/beam.
