In the present invention, "enable", "employ", "apply", "execute", and the like may be used interchangeably.
The prior art to which embodiments of the present invention relate is briefly described below.
The measurement model of NR is shown in FIG. 1, in which:
-A: measurement samples of a single beam inside the physical layer.
Layer 1 filtering: layer 1 (L1) filtering process based on single beam measurement samples inside the physical layer.
-A 1 : the measurement result of the single beam obtained after the filtering by the layer 1 is reported from the physical layer to the RRC layer (i.e. from L1 to L3).
-beam selection/combining: selecting/combining some measurement from the beam measurement results reported by the physical layer to obtain the measurement result of the cell.
-B: the cell measurement results are reported to the RRC layer (i.e., L3).
Layer 3 cell quality filtering: and carrying out filtering processing on the cell measurement result according to the filtering parameters and the like.
-C: the measurement results are used as input for reporting the evaluation of the criterion.
-evaluating reporting criteria: and evaluating whether the measurement report needs to be triggered to be reported or not according to the configuration parameters of the measurement report.
-D: and reporting the measurement report containing the cell measurement result to the base station at an air interface.
Layer 3 beam filtering: layer 3 (L3) filtering is performed on the measurements of the single beam.
-E: measurements of the individual beams obtained after the filtering operation.
-beam selection reporting: x beam measurements are selected from the K beam measurements obtained at point E.
-F: and reporting the measurement report containing the beam measurement result to the base station on an air interface.
In the RRC connected state, the base station may perform measurement configuration on the UE through an RRC reconfiguration message (rrcreeconfiguration), where the measurement configuration may include an s-MeasureConfig cell, and the cell may include a threshold configuration of RSRP. If the cell is not configured by the base station or is configured and the RSRP of the SpCell cell obtained by filtering the cell by the UE through the layer 3 is lower than the configured RSRP threshold value, the UE measures the adjacent cell according to the measurement configuration; otherwise, the UE may not perform measurement of the neighbor cell. Wherein the SpCell refers to the PCell of the MCG or the PSCell of the SCG for DC scenarios and to the PCell for non-DC scenarios.
In the RRC connected state, the base station may send measurement configuration to the UE, where the measurement configuration includes measurement object configuration, measurement report configuration, measurement identifier configuration, quality configuration, measurement gap (gap) configuration, and the like. The type of triggered measurement report, including periodic and event measurement reports, may be configured in a measurement report configuration. For the event measurement report, the base station configures trigger criteria of the measurement report, that is, various RSRP/RSRP and time threshold values, and the UE may send the measurement report to the base station when the criteria are met. After sending the event-triggered measurement report, the UE periodically reports the measurement report for the event to the base station before the response from the base station is not obtained.
In 3GPP release 16, RRM measurement relaxation in RRC idle and inactive states is standardized and defined in 3GPP latest standard specification TS 38.304 (see section 5.2.4.9). And the base station broadcasts RRM measurement relaxation configuration parameters in an RRC idle state and an inactive state through system messages, wherein the configuration parameters comprise switches for low-speed movement evaluation and non-cell edge evaluation, decision thresholds and decision time parameters for low-speed movement and non-cell edges and the like. If the base station is configured with low-rate evaluation and non-cell edge evaluation at the same time, the UE evaluates whether the UE moves at a low speed or is not positioned at the cell edge, and if the UE evaluates that the UE moves at a low speed and is not positioned at the cell edge and performs normal neighbor cell measurement for a period of time after the UE selects or reselects the current cell (the time base station broadcasts through a system message), the UE may not perform neighbor cell measurement or perform no neighbor cell measurement for a very long period of time; if the UE evaluates that only one of low-speed movement or not at the cell edge is satisfied, the UE may perform neighbor cell measurement with a longer time interval. If the base station only configures low speed evaluation, the UE evaluates that the UE moves at a low speed, and the UE can adopt a longer time interval to measure the adjacent cells. If the base station only configures non-cell edge evaluation, the UE evaluates that it is not at the cell edge, and the UE may use a longer time interval to perform neighbor cell measurement.
For RRC connected state, the base station may configure the UE with static evaluation criteria and/or non-cell-edge evaluation criteria for RRM measurement relaxation. When the UE judges that the UE meets the evaluation criterion of RRM measurement relaxation, the information is reported to the base station through UE auxiliary information or a measurement report explicitly or implicitly. The base station, upon receiving this information, may instruct the UE to enable RRM measurement relaxation.
Hereinafter, a description will be given of the related art of the present invention.
By the invention, the UE can adopt a proper RRM measurement relaxation method when the RRM side relaxation criterion is met according to different configuration conditions of the base station, thereby achieving the effects of further saving power consumption and not influencing transmission performance.
Hereinafter, several embodiments of the present invention for the above-described problems are described in detail.
Example 1
Fig. 2 is a schematic diagram illustrating a method performed by a user equipment according to an embodiment of the present invention.
The method performed by the user equipment according to embodiment 1 of the present invention will be described in detail below with reference to the basic procedure shown in fig. 2.
The present embodiment includes a first step, a second step, and a third step.
Optionally, in step one (step S201 shown in fig. 2), the UE receives an RRM measurement relaxation criterion configuration (e.g., a static criterion) transmitted by the base station.
Wherein, the configuration of the RRM measurement relaxation criteria transmitted by the base station may be through a system message (such as but not limited to one of SIB1, SIB2, SIB3, SIB4, SIB5, or adding a new SIB), or RRC dedicated signaling (such as but not limited to an RRC reconfiguration message, an RRC release message, etc., or adding a new RRC message).
The static criteria may contain information of RSRP and/or RSRQ change thresholds, time thresholds, etc. Alternatively, different inactivity criteria may be configured for the same frequency, different frequency, and different standard (inter-RAT), respectively.
Optionally, in step two (step S202 shown in fig. 2), the UE performs the evaluation of the RRM measurement relaxation criterion. Wherein, the static criterion satisfies the condition, such as: the RSRP and/or RSRQ of the SpCell changes less than the RSRP and/or RSRQ change threshold for a period of time that is a time threshold configured in the static criteria. If the UE determines, through evaluation, that the RRM measurement relaxation criteria are met (i.e., the inactivity criteria are met), the UE sends a report to the base station. Alternatively, the report may be transmitted to the base station through a UEAssistanceInformation message or a measurement report message.
Optionally, in step three (step S203 shown in fig. 2), the UE receives an RRM relaxation measurement configuration or an RRM relaxation measurement enabling instruction in a connected state sent by the base station, where the instruction or configuration may include one or more of the following information:
1) A same-frequency RRM relaxation measurement indication or a same-frequency RRM relaxation measurement configuration;
2) An inter-frequency RRM relaxation measurement indication or configuration;
3) A heterogeneous RRM relaxation measurement instruction or configuration;
4) Different from 2) 3), the different point is that one instruction or the same configuration is used for simultaneously indicating or configuring the different frequencies and different systems;
5) Methods of RRM relaxation measurements, for example: a relaxation measurement scale factor (scaler factor), time for not performing neighbor measurement, a relaxation measurement method type value, a relaxation measurement method type index, and the like; optionally, the same frequency, different frequency, and different mode may use different RRM transmission measurement methods, and at this time, the RRM relaxation measurement method may distinguish the indication or configuration of the same frequency, different frequency, and different mode, respectively.
RRM measurement relaxation methods may include, but are not limited to: and not performing neighbor cell measurement, or not performing neighbor cell measurement for a long time (for example, several hours) (the same frequency, different frequency, and different standard may correspond to different time lengths), or lengthening a neighbor cell measurement interval by a scaling factor (the same frequency, different frequency, and different standard may correspond to different scaling factors).
Optionally, the RRM relaxation measurement configuration or the RRM relaxation measurement enabled indication may be sent by the base station to the UE by means of RRC dedicated signaling or MAC CE. And the UE starts to adopt a corresponding RRM measurement relaxation method to perform RRM measurement relaxation according to the instruction or configuration of the base station.
Example 2
And the UE receives the cell measurement threshold information in the RRC connection state sent by the base station. The measurement threshold information includes one or more of:
1) A same-frequency RSRP threshold and a same-frequency RSRQ threshold;
2) Pilot frequency RSRP threshold and pilot frequency RSRQ threshold;
3) A different-mode RSRP threshold and a different-mode RSRQ threshold;
4) Pilot frequency/different standard RSRP threshold, and pilot frequency/different standard RSRQ threshold.
Alternatively, the measurement threshold information may be sent to the UE through a system message or RRC dedicated signaling (e.g., RRC reconfiguration message).
After the UE receives configuration for RRM measurement relaxation in a connected state of a base station or an instruction for enabling RRM measurement relaxation in the connected state, the UE compares the quality of the cell with the measurement threshold information of the cell in the connected state, and judges which RRM measurement relaxation method is adopted under the conditions of same frequency, different frequency and different modes.
RRM measurement relaxation methods may include, but are not limited to: and not performing neighbor cell measurement, or not performing neighbor cell measurement for a long time (for example, several hours) (the same frequency, different frequency, and different standard may correspond to different time lengths), or lengthening a neighbor cell measurement interval by a scaling factor (the same frequency, different frequency, and different standard may correspond to different scaling factors).
One possible implementation is exemplified by:
1) When UE receives configuration or indication of loosening RRM measurement in a connection-enabled state of a base station, or configuration or indication of loosening RRM measurement in a same frequency in a connection-enabled state of the base station, if RSRP of a local cell is greater than a threshold of RSRP in the same frequency and RSRQ of the local cell is greater than the threshold of RSRQ in the same frequency, the UE does not perform measurement of an adjacent cell; if the RSRP of the cell is less than or equal to the same-frequency RSRP threshold and the RSRQ of the cell is less than or equal to the same-frequency RSRQ threshold, the UE does not measure the adjacent cells within a period of time;
2) When UE receives configuration or indication of loosening measurement of enabling connection state RRM of a base station, or configuration or indication of loosening measurement of enabling connection state pilot frequency/different-mode RRM of the base station, if RSRP of a cell is larger than a same-frequency RSRP threshold and RSRQ of the cell is larger than the same-frequency RSRQ threshold, the UE does not measure an adjacent cell within a period of time; and if the RSRP of the cell is less than or equal to the same-frequency RSRP threshold and the RSRQ of the cell is less than or equal to the same-frequency RSRQ threshold, the UE elongates the neighbor cell measurement interval through the scale factor.
Example 3
The embodiment comprises a first step, a second step, a third step and a fourth step.
Optionally, in step one, when the base station initiates handover to the UE, the source base station sends a handover preparation information message (message 1) to the target base station. Optionally, the UE static state indication is carried in the message. For example, when the UE is in a stationary state, the indication position is 1, otherwise, the indication position is 0; or carrying the indicating bit when the UE is in a static state, otherwise not carrying the indicating bit. Optionally, the inactivity status indication indicates that the UE satisfies the inactivity criterion. Optionally, if the message carries an indication of whether the UE is a recap UE, the dormant state indication is set only when the recap UE indicates that the UE is a recap UE.
Optionally, in step two, after receiving the handover preparation information message, the target base station may determine whether to let the UE enable the RRM measurement to be relaxed according to the static state indication of the UE. If the RRM measurement is enabled to be relaxed, it may be sent to the source base station via a handover command message (message 2).
Optionally, in step three, after receiving the handover command message (message 2), the source base station sends it to the UE through an RRC reconfiguration (RRCReconfiguration) message.
Optionally, in step four, the UE receives an RRC reconfiguration message with synchronous reconfiguration (reconfiguration within sync), and performs one of the following operations:
1) Performing RRM measurement relaxation according to an enabled RRM measurement relaxation configuration or indication in the RRC reconfiguration message; or not according to an enabled RRM measurement relaxation configuration or indication (i.e., not enabled, or disabled) in the RRC reconfiguration message.
2) And if the UE adopts the RRM relaxation measurement, immediately stopping the RRM relaxation measurement and adopting a normal RRM measurement mode instead.
