Description

Determination method, configuration method, terminal and network side equipment of measurement configuration information
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for determining measurement configuration information, a configuration method, a terminal, and a network device.
Background
In the prior art, when a target cell SSB (Synchronization Signal/PBCH Block) is the same as a center frequency point of a serving cell SSB and a subcarrier interval of two SSBs, it is necessary to perform common-frequency measurement. When the center frequency point of the target cell SSB is different from that of the serving cell SSB or the subcarrier spacing of the two SSBs is different, the inter-frequency measurement or the measurement interruption needs to be performed.
The SMTC (SS/PBCH block measurement timing configuration) is used to indicate the SSB measurement configuration of the terminal, including period, duration, and offset, and is mainly used for intra-frequency measurement. The length of the Measurement gap is SSB transmission time + RF (Radio Frequency) modulation time, and the NR Measurement gap is divided into per UE (terminal-based) and per FR (FR-based). Per UE configuration means that measurement of all frequency points to be measured is executed based on a set of measurement interval configuration. Per FR configuration means that a terminal can be configured with two measurement intervals simultaneously, which are used for FR1 and FR2, respectively, and whether Per FR interval is supported or not is reported in the terminal capability.
In NR (New Radio, New air interface), for the case of common-frequency measurement, if there is a scheduling restriction (SSB is different from the subcarrier spacing SCS of data, FR2 frequency point measurement, and there is no SSB in the active bandwidth), a measurement interval is also needed. For the case of inter-frequency measurement, a measurement interval may not be needed if the measurement MO is within the active bandwidth of the terminal.
In the traditional common-frequency measurement and different-frequency measurement, because the base stations are all on the ground, and the transmission delay difference from different ground base stations to the terminal is smaller, the length of a measurement window is smaller. For a non-terrestrial network, the transmission delay difference between a satellite and a terminal is large, especially, the transmission delay difference between an LEO (Low Earth orbit) and a GEO Earth orbit (Geostationary orbit) to the terminal is even in the order of hundred milliseconds, and if the existing measurement configuration is used, the terminal may not detect the SSB of the target cell.

In order 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.
As shown in fig. 1, an embodiment of the present invention provides a measurement method, executed by a terminal, including:
step 101, a terminal acquires or determines time delay difference information;
102, a terminal receives first information sent by network side equipment; the first information includes: at least one measurement configuration information;
and 103, the terminal determines measurement configuration information for measuring the cell or the frequency point according to the time delay difference information and the first information.
The first information includes: at least one measurement configuration information, where the measurement configuration information may be measurement configuration information of 1 cell or multiple cells, and a cell herein may serve a cell, may also be a neighboring cell, or may be described as a target cell; the measurement configuration information may also be measurement configuration information of 1 frequency point or multiple frequency points, where the frequency point may serve a frequency point, may also be an MO (measurement object), or may be described as a target frequency point.
In this embodiment of the present invention, the measurement configuration information includes SMTC configuration information and/or measurement interval configuration information (which may be described as a measurement gap or a gap pattern), and the SMTC and/or the measurement interval may be used for a common frequency or an inter-frequency, may be configured in a broadcast message, or may be configured in an MO, which is not specifically limited herein.
In the embodiment of the invention, the measurement configuration information and the delay inequality information have a corresponding relation, and one measurement configuration information corresponds to at least one delay inequality information. For example, a different delay difference step table is provided, which contains different delay difference information and measurement configuration information corresponding to each delay difference information.
Optionally, for the SMTC configuration, a corresponding relationship between the SMTC and the delay difference information is: the period (SMTC period), the offset (offset), the duration (SMTC duration), a combination of two or a combination of three is proportional to the delay difference, and the larger the delay difference is, the larger the period, the offset, the duration, the combination of two or a combination of three is, the larger the value is.
Optionally, for the measurement interval configuration, the corresponding relationship between the measurement interval and the delay difference information is: the period (Measurement gap periodicity) or the duration (Measurement gap length) or the combination of the period (Measurement gap periodicity) and the duration (Measurement gap length) is in direct proportion to the delay difference, and the period or the duration or the combination of the period and the duration is configured with a larger value when the delay difference is larger.
As an alternative embodiment, in the non-terrestrial network, some measurement configurations need to be added to adapt to the larger delay difference from the terminal to the target cell and the serving cell, and specific measurement configuration information is not limited herein.
Optionally, the measurement configuration information includes: the configuration parameters are measured as time varying parameters. For example, the measurement configuration information may be a function that varies with time, and different measurement configuration information may be applied with different time shifts (e.g., Δ t shift rates). Such as measuring the time-varying parameter of the configuration parameter as the drift rate.
As another alternative embodiment, step 101 includes at least one of:
the terminal determines the transmission delay difference from at least the terminal to two cells and/or at least two frequency points according to the self-position information and the satellite ephemeris information;
and the terminal determines the transmission delay difference from the terminal to the first cell and from the terminal to the second cell according to the TA (timing Advance) value of the first cell and the TA value of the second cell.
In at least one embodiment of the present invention, the delay inequality information includes at least one of:
the maximum value of the transmission delay difference from the terminal to at least two cells;
the minimum value of the transmission delay difference from the terminal to at least two cells;
the average value of the transmission delay differences from the terminal to at least two cells;
the maximum value of the transmission delay difference from the terminal to at least two frequency points;
the minimum value of the transmission delay difference from the terminal to at least two frequency points;
and the average value of the transmission delay differences from the terminal to at least two frequency points.
For example, the at least two cells are a target cell and a serving cell; for another example, the at least two frequency points are: the frequency allocation method comprises a target frequency point and a service frequency point, wherein the target frequency point is a frequency point of a target cell, and the service frequency point is a frequency point of a service cell.
In the embodiment of the present invention, a method for a network side device to send first information includes:
in the first mode, the network side device configures a plurality of measurement configuration information corresponding to different delay inequality information for a cell to the terminal, where N measurement configuration information corresponding to a cell respectively correspond to different delay inequalities of the cell and a serving cell.
The terminal calculates the time delay difference between at least one target cell and a service cell according to the position information of the terminal and the ephemeris information of the satellite; the terminal finds corresponding measurement configuration information in the first information according to the calculated time delay difference, and then performs measurement according to the measurement configuration information. If the measurement is the measurement applying the GAP, the terminal reports the finally selected measurement configuration information to the serving cell to ensure the serving cell to schedule the terminal correctly subsequently.
In a second mode, the network side device periodically configures different measurement configuration information to the terminal, in this mode, step 101 includes:

the information or frequency points corresponding to the measurement configuration information are different;
the time delay difference information corresponding to the measurement configuration information is different;
the measurement configuration information includes different measurement parameters.
And the terminal calculates the time delay difference between the at least one target cell and the serving cell and the measurement configuration information in the first information, and executes measurement when waiting for receiving the corresponding measurement configuration information provided by the serving cell.
In another alternative embodiment of the present invention, since the moving speed of the satellite is relatively fast, the error rate of the measurement configuration may be much higher than that of the ground network when the measurement configuration is actually executed; considering that the satellite moves rapidly, the credibility of the results of the measurement performed by the terminal according to the selected measurement configuration may be reduced, and therefore the robustness of the measurement mechanism needs to be improved, the following three schemes are provided in the embodiments of the present invention:
in a first scheme, selecting measurement configuration information corresponding to a delay inequality calculated by a terminal to measure a target cell includes:
after selecting the measurement configuration information corresponding to the time delay difference information calculated by the terminal, if the target timer runs and is not overtime, measuring the target cell by using the selected measurement configuration information;
or,
and after selecting the measurement configuration information corresponding to the time delay difference information calculated by the terminal, if the target timer is overtime, reselecting the measurement configuration information.
Namely, a new timer (target timer) is introduced for monitoring the executable duration of the current measurement configuration information, and the value range of the timer is set according to the distance between the satellite and the terminal and the relative movement speed. The setting method of the timer can be as follows: assuming that the service quality of the satellite deteriorates if the distance between the satellite and the terminal exceeds a certain threshold condition, the maximum value of the timer may be calculated from the distance threshold and the relative movement speed between the satellite and the terminal.
Once the target timer is about to time out or time out, the measurement configuration information of the terminal needs to be pre-updated in advance according to the method described in step 101.
In a second aspect, after determining measurement configuration information for measuring a cell or a frequency point, the method further includes:
acquiring time delay difference information of different cells or frequency points reaching a terminal, and adjusting selected measurement configuration information according to the time delay difference information;
and measuring the cell or the frequency point by using the adjusted measurement configuration information, and sending the adjusted measurement configuration information to the network side equipment.
Namely, the terminal adaptively adjusts the measurement configuration information, and the terminal adjusts the measurement configuration information (such as the offset, duration, period, and the like of the SMTC and/or the measurement interval) according to the acquired delay inequality information of different cells or different frequency points reaching the terminal. And the terminal reports the adjusted SMTC and/or the adjusted measurement interval to the network. Further, the terminal may report the adjusted SMTC and/or the measurement interval corresponding to different measurement targets (measurement frequency points). (this may help the network determine when data scheduling may be performed).
Scheme three, the method still includes:
if the time delay difference between at least two cells calculated by the terminal is greater than a first threshold value, sending third information to network side equipment, wherein the third information comprises: indication information indicating that the current measurement configuration information is invalid and new delay inequality information.
That is, a delay inequality threshold (i.e. a first threshold) is set, the terminal compares the calculated delay inequality between the target cell and the serving cell with the threshold, if the calculated delay inequality exceeds the threshold, the terminal reports an indication that the current measurement configuration information of the network (the reporting mode may be an RRC signaling or an MAC CE) is invalid and the latest delay inequality information, and the network provides the terminal with new measurement configuration information according to the latest delay inequality information reported by the terminal.
As another optional embodiment, the measurement configuration information includes: in case of a measurement interval configuration, the method further comprises at least one of:

if the terminal has configured the measurement interval configuration of FR2 currently, releasing the configured measurement interval configuration of FR2, and determining the measurement interval configuration of FR2 according to the received indication of the measurement configuration information;
if the terminal has configured the terminal-based measurement interval configuration currently, releasing the configured terminal-based measurement interval configuration, and determining the terminal-based measurement interval configuration according to the indication of the received measurement configuration information;
wherein, the first subframe of each measurement interval in the measurement interval configuration indicated by the measurement configuration information is determined by at least one of a system frame number SFN, a measurement period T, a measurement interval offset gapOffset, a subframe number subframe, a measurement interval offset gapOffset ntn of the non-ground network, and a measurement interval repetition period MGRP.
For example, the first subframe of each measurement interval in the measurement interval configuration indicated by the measurement configuration information occurs on a subframe satisfying the following condition:
SFN mod T=FLOOR((gapOffset+gapOffsetNTN)/10);
subframe=(gapOffset+gapOffsetNTN)mod 10;
with T=MGRP/10;
wherein, SFN represents system frame number, T represents measurement period, gapOffset represents measurement interval offset, subframe represents subframe number, gapOffsetNTN represents measurement interval offset of non-ground network, and MGRP represents measurement interval repetition period. The gapOffsetNTN may be positive, negative, or 0. FLOOR represents a rounding down operation, mod being a remainder function.
For example, the definition of the above parameters in the GAP configuration information is as follows:
