Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a measurement configuration method and a terminal device.
Background
In an LTE (Long Term Evolution) system, for measurement of an idle state of a UE (User Equipment), a trigger condition for when to perform measurement and a requirement related to the measurement are defined. When the UE performs cell selection or reselection in an idle state, different cells are measured, and RSRP (Reference Signal Receiving Power) and RSRQ (Reference Signal Receiving Quality) of Reference signals of the cells are measured to serve as Reference conditions for subsequently determining whether the cells can reside. In the LTE system, CRS (Cell-specific Reference Signal) is generally measured, and in NR (New Radio ), SSB (Synchronization Signal Block) is measured.
The UE performs cell selection or reselection in an idle state. The cell selection is divided into initial cell selection and cell selection by using the stored information, the UE obtains values of different cells by measuring RSRP, RSRQ and the like, and obtains other parameters by system information and self capability level of the cells to see whether the S criterion of the cell selection is met, and the UE can be resided on the cells if the S criterion of the cell selection is met and no other limitation is met. Meanwhile, when the UE meets a certain measurement criterion, the UE also starts a cell reselection process of the same frequency or different frequencies, and the relevant cells are sorted according to the R criterion so as to reselect the cell with higher priority.
The LTE system introduces a carrier aggregation technology, where a UE performs connection communication with a network through multiple cells (cells), one of the multiple cells is a Pcell (primary cell), and the other cells are scells (secondary cells). Wherein the Scell has an activated state and a deactivated state, the Pcell has no deactivated state, and the activated state is consistently maintained.
Currently, the UE in idle state usually uses the measurement SSB to obtain the corresponding measurement result. However, since the SSB is not fine enough, an accurate measurement result cannot be obtained.

Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive labor.
Referring to fig. 1, an embodiment of the present invention provides a measurement configuration method, which is applied to a terminal device, and includes the following steps:
step 101: and receiving the configuration information sent by the network equipment.
The configuration information is used to instruct the terminal device to measure a CSI-RS (Channel State indication Reference Signal) in an idle State.
In a specific application, when the terminal device is in a connected state, the network side, such as the base station, may initiate a Radio Resource Control (RRC) connection release process according to a requirement, so as to release or suspend the RRC connection. The configuration information for the CSI-RS measurement may be transmitted to the terminal device through an RRC connection release message. Specifically, step 101 may include:
and the terminal equipment receives the configuration information sent by the network equipment through the RRC connection release message.
Note that this CSI-RS measurement configured in connected state is terminal-specific (UE-specific). The terminal equipment can measure the CSI-RS in an idle state according to the received configuration information.
Further, the configuration content in the configuration information may include at least one of the following: measurement targets (Measurement objects), Measurement report configurations (Reporting configurations), Measurement characteristics (Measurement identities), Measurement Quantity configurations (Quantity configurations), Measurement gaps (Measurement gaps), and the like.
In the embodiment of the invention, the network side can configure the CSI-RS measurement of the terminal equipment in a connected state and can also configure the CSI-RS measurement through a broadcast message. The Broadcast message includes, but is not limited to, PBCH (Physical Broadcast Channel), RMSI (Remaining Minimum System Information) or SIB (System Information Block), and the like. Specifically, step 101 may include:
the terminal equipment receives the configuration information sent by the network equipment through the broadcast message.
Note that this CSI-RS measurement configured by broadcast message is cell specific. After the terminal equipment resides in the cell, the configuration of the CSI-RS of the cell can be obtained by reading the cell broadcast message so as to measure the CSI-RS subsequently.
In addition, the configuration of the CSI-RS measurement of the terminal equipment in an idle state can be realized through the pre-configuration of the terminal equipment.
Step 102: and when the terminal equipment is in an idle state, measuring the CSI-RS to obtain a measurement result.
Specifically, after the terminal device is configured to perform CSI-RS measurement in an idle state, the terminal device may measure the CSI-RS in the idle state to obtain a corresponding measurement result.
According to the measurement configuration method, the CSI-RS is measured in the idle state by the configuration terminal equipment, and the CSI-RS is measured when the terminal equipment is in the idle state to obtain the measurement result.
In the embodiment of the present invention, the measurement of the terminal device in the idle state (i.e., the idle state measurement) may include measurement of the CSI-RS, and may also include measurement of the SSB, which is determined according to the configuration. According to the configuration, the terminal equipment can measure the CSI-RS and/or the SSB in an idle state. Wherein, the measuring CSI-RS can be at least one of the following measuring modes: and carrying out co-frequency measurement based on the CSI-RS and pilot frequency measurement based on the CSI-RS. The measurement SSB may be at least one of the following measurement modes: the measurement of co-frequency based on SSCH block, the measurement of co-frequency based on PBCH block, the measurement of pilot frequency based on SSCH block and the measurement of pilot frequency based on PBCH block. And the corresponding measurement result may be at least one of the following measurement results: the measurement method comprises the steps of CSI-RS-based co-frequency measurement results, CSI-RS-based pilot frequency measurement results, SSCH block-based co-frequency measurement results, PBCH block-based co-frequency measurement results, SSCH block-based pilot frequency measurement results and PBCH block-based pilot frequency measurement results. Specifically, step 102 may include:
and when the terminal equipment is in an idle state, measuring the CSI-RS and the SSB to obtain corresponding measurement results.
It is noted that, regardless of CSI-RS based measurements or SSB based measurements, the corresponding measurement performance may include: RSRP (Reference Signal Receiving Power), rsrq (Reference Signal Receiving Quality) represents Reference Signal Receiving Quality, SINR (Signal to Interference plus Noise Ratio), CQI (Channel Quality Indicator) and the like.
Further, after obtaining the measurement result in the idle state based on the measurement CSI-RS and/or the SSB, the terminal device may perform cell selection or reselection according to the measurement result.
Therefore, compared with the current method that only the measurement result obtained by measuring the SSB is taken as the judgment basis for cell selection or reselection, the method considers that the measurement result obtained by measuring the CSI-RS is taken as the judgment basis for cell selection or reselection, and because the CSI-RS wave beam is finer than the SSB, the smooth cell selection or reselection can be further ensured.
Since measurement requirements of different reference signals are generally different when measuring different reference signals, when idle state measurement of the terminal device may include CSI-RS measurement and SSB measurement, two different sets of cell selection or reselection parameters may be configured for the terminal device to select a corresponding parameter set according to the measured reference signals to perform cell selection or reselection. Correspondingly, referring to fig. 2, the measurement configuration method according to the embodiment of the present invention may further include:
step 103: configuring two sets of cell selection or reselection parameters, wherein one set of cell selection or reselection parameters in the two sets of cell selection or reselection parameters corresponds to a measurement result obtained by measuring CSI-RS, and the other set of cell selection or reselection parameters corresponds to a measurement result obtained by measuring SSB;
step 104: and selecting the corresponding configured cell selection or reselection parameters from the measurement results to perform cell selection or reselection.
It should be noted that, in fig. 2, step 103 is located after step 102, but in a specific implementation, step 103 may also be located before step 102, even before step 101, and this is not limited by the embodiment of the present invention.
Each of the two sets of cell selection or reselection parameters may include at least one of: cell selection received signal level value Srxlev, cell selection received signal quality value Squal, temporary inter-cell offset value QoffsettempThe measured cell receiving signal level value QrxlevmeasThe measured cell received signal quality value QqualmeasMinimum receiving signal level value Q required by cellrxlevminMinimum received signal quality value Q required for a cellqualminMinimum received signal level offset Q required for a cellrxlevminoffsetMinimum required received signal quality offset value Q of cellqualminoffsetPower compensation value Pcompennsation, maximum up going transmission power P allowed by cellEMAX1And PEMAX2And the maximum radio frequency output power P of the terminal based on the terminal gradePowerClassAnd the like.
In the embodiment of the invention, when the terminal equipment selects or reselects the cell according to the measurement result, the terminal equipment can select the cell based on the S criterion according to the measurement result; alternatively, cell selection is performed based on the R criterion according to the measurement results.
Wherein the S criterion of the cell selection based on the SSB measurement result can be reused for the cell selection based on the CSI-RS measurement result, i.e. Srxlev is satisfied>0 and Squal>At 0, the cell may be considered to satisfy the camping condition, and the Srxlev and the Squal may be the sum or difference between the following parameters: temporary inter-cell offset value QoffsettempThe measured cell receiving signal level value QrxlevmeasThe measured cell received signal quality value QqualmeasMinimum receiving signal level value Q required by cellrxlevminMinimum received signal quality value Q required for a cellqualminMinimum received signal level offset Q required for a cellrxlevminoffsetMinimum required received signal quality offset value Q of cellqualminoffsetPower compensation value Pcompennsation, maximum up going transmission power P allowed by cellEMAX1And PEMAX2And the maximum radio frequency output power P of the terminal based on the terminal gradePowerClassAnd the like.
In the cell reselection, the R criterion is used for sequencing the cells, so that a better cell can be reselected. It should be noted that when comparing channel quality between cells, the same reference signal type should be used, i.e. CSI-RS measurement result is compared with CSI-RS measurement result and SSB measurement result is compared with SSB measurement result, but measurement results of different reference signal types of different cells may not be compared, e.g. CSI-RS measurement result of cell 1 is compared with SSB measurement result of cell 2.
In the embodiment of the invention, when the terminal equipment obtains the CSI-RS measurement result in an idle state, the terminal equipment can report the available measurement result to the network equipment after entering a connected state, receive the indication information which is sent by the network equipment and used for indicating the measurement result to be reported, and report the corresponding measurement result to the network equipment according to the indication information, so that the network equipment can perform subsequent operation according to the measurement result.
Optionally, the CSI-RS measurement result may be used for the network device to configure the secondary cell of the terminal device and activate the secondary cell. Compared with SSB, the CSI-RS wave beam is finer, and the CSI-RS measurement result is more accurate, so that the network side can quickly configure and activate the auxiliary cell of the terminal equipment by using the CSI-RS measurement result.
For example, referring to fig. 3, the procedure of rapidly activating the secondary cell according to the embodiment of the present invention may be:
step 31: the method comprises the steps that terminal equipment (UE) receives measurement configuration information of a base station and is used for configuring the UE to measure CSI-RS in an idle state;
step 32: the UE measures the CSI-RS in an idle state to obtain a CSI-RS measurement result;
step 33: the UE initiates RRC connection and sends an RRC connection establishment request message to the base station;
step 34: the base station sends RRC connection establishment response information to the UE;
step 35: when the RRC connection is completed, the UE sends an RRC connection establishment completion message to the base station, and the RRC connection establishment completion message can carry indication information for indicating that a measurement result is available;
step 36: when a measurement result of the UE is needed, the base station sends indication information for indicating reporting of the measurement result to the UE;
step 37: the UE reports a CSI-RS measurement result to the base station;
step 38: the base station configures and activates an auxiliary cell of the UE by using the CSI-RS measurement result;
step 39: and when the activation of the secondary cell is completed, the UE and the base station transmit and receive data by using the secondary cell.
