In this application.

Technical field

The present invention relates to the field of communications, and in particular, to a method and a device for transmitting measurement parameters.

Background technique

Radio Resource Management (RRM): Provides quality of service for wireless user terminals in the network under limited bandwidth conditions. The basic starting point is uneven distribution of network traffic, channel characteristics due to channel degradation and interference. In the case of fluctuations and the like, the allocation and available resources of the wireless transmission part and the network are flexibly allocated and dynamically adjusted, thereby maximizing the utilization of the wireless spectrum, preventing network congestion and keeping the signaling load as small as possible. RRM includes power control, channel allocation, scheduling, handover, access control, load control, and adaptive code modulation.

Currently, in the Long Term Evolution (LTE) system, the cell handover in the RRM adopts a measurement method based on the downlink reference signal, that is, the base station sends a reference signal to the user equipment (User Equipment, UE) in its coverage area (Reference). Signal, RS), usually sends a Cell-Specific Reference Signal (CRS) of a fixed time-frequency resource; when a certain UE receives the CRS sent by the base station, it performs measurement according to the CRS, and reports the measurement result to the base station. When receiving the measurement result fed back by the UE, the base station determines, according to the measurement result, whether the UE needs to perform cell handover.

In the LTE system, the UE performs measurement reporting according to the CRS, and does not consider the case where the base station transmits multiple transmit beams. However, in the New Radio (NR) system, the base station may send multiple transmit beams, if the UE If the CRS is still used for measurement reporting, it is necessary to report the measurement for each transmit beam, which will increase the reporting overhead.

A brief description of the Synchronization Signal Block (SS block) will be given below. Please refer to FIG. 2 , which is a schematic diagram of the configuration of the time-frequency resource of the SS block. As can be seen from FIG. 2, the time-frequency resource structure of the SS block is the same as the time-frequency resource structure in the LTE system, and has 14 symbols in the time dimension, representing one frame, and 12 subcarriers in the frequency dimension.

Frequency resources. The DM-RS is used for correlation demodulation of a Physical Broadcast Channel (PBCH), and is configured by a network device. It can be understood that one SS block corresponds to one beam of the network device, and the measurement of the beam is actually measuring the measurement signal in the SS block corresponding to the beam. It can also be understood that a plurality of SS blocks correspond to one beam of the network device, and the measurement of the beam is actually measuring the measurement signals in the plurality of SS blocks corresponding to the beam.

The measurement parameter transmission method provided by the embodiment of the present invention will be described in detail below.

FIG. 3 is a schematic flowchart of a method for sending a measurement parameter according to an embodiment of the present invention. The method is introduced from the perspective of interaction between a network device and a user equipment, and the method includes but is not limited to the following steps:

Step S101: The network device sends a measurement signal corresponding to multiple beams. Optionally, the network device sends the multiple beams to the user equipment.

The multiple beams include two beams, or more than two beams, and the like. The specific number is set by the network device, and the beam may be a transmit beam of the network device, instead of a transmit beam of the user equipment. Each of the plurality of beams corresponds to a measurement signal, which may be used for measurement, and may be a signal for inter-cell or intra-cell mobility measurement.

Step S102: The user equipment receives the measurement signal corresponding to the multiple beams. Optionally, the user equipment receives the measurement signal corresponding to the multiple beams sent by the network device.

Step S103: The user equipment measures the received measurement signals corresponding to the multiple beams to obtain beam measurement parameters.

Specifically, when receiving the measurement signals corresponding to the multiple beams, the user equipment measures the measurement signals corresponding to the multiple beams.

In a first possible implementation manner, the SS-block includes only the synchronization signal, and does not include other reference signals, and the measurement signal includes the synchronization signal, and the user equipment corresponds to the synchronization of the multiple beams. The signal is measured to obtain a plurality of synchronization signal (SS) measurement parameters corresponding to the multiple beams, and the number of the plurality of SS measurement parameters is the same as the number of the multiple beams, that is, one beam corresponds to one SS. Measurement parameters.

In a second possible implementation manner, the SS-block includes a DM-RS in addition to the synchronization signal. For example, FIG. 2 includes an SS and a DM-RS, then the measurement signal includes the synchronization signal and the DM- And performing, by the user equipment, the synchronization signal corresponding to the multiple beams, to obtain multiple SS beam measurement parameters corresponding to the multiple beams, and performing the DM-RS corresponding to the multiple beams The measurement may obtain a plurality of DM-RS measurement parameters corresponding to the multiple beams, where the number of the plurality of DM-RS measurement parameters is the same as the number of the multiple beams, and the beam measurement parameter corresponding to a certain beam may be The combination of the SS measurement parameter corresponding to the beam and the DM-RS measurement parameter corresponding to the beam may be averaged or superimposed, and the combination mode is not limited herein. The accuracy of the measurement results of the second possible implementation is higher than the first possible implementation.

If the SS-block includes other reference signals in addition to the synchronization signal and the DM-RS, the user equipment also measures other reference signals corresponding to the multiple beams, and performs measurement parameters with the SS, DM-RS measurement. The parameters are combined to obtain beam measurement parameters corresponding to each beam. At this point, the accuracy of the measurement results may be higher than the first and second possible implementations.

It should be noted that there is also a possible implementation manner, the SS-block includes the synchronization signal and the DM-RS, but the user equipment only measures the synchronization signal corresponding to the multiple beams. The plurality of SS measurement parameters corresponding to the multiple beams are not measured by the DM-RS corresponding to the multiple beams.

It should be noted that the beam measurement parameter corresponding to a certain beam may be the SS measurement parameter corresponding to the beam, or may be the combination of the SS measurement parameter corresponding to the beam and the DM-RS measurement parameter, and may also be the SS corresponding to the beam. Measurement parameters, DM-RS measurement parameters, and other reference signal measurement parameters.

The measurement of the measurement signal corresponding to the beam may be, but is not limited to, measuring the measurement signal in the synchronization signal block corresponding to the beam. Therefore, if the measurement signal corresponding to the beam is measured, the measurement signal in the synchronization signal block corresponding to the beam is performed. The beam measurement parameter obtained by measuring the measurement signal corresponding to the multiple beams by the user equipment may also be defined as an SS-block-measurement parameter. The beam measurement parameters described below are described by taking SS-block-measurement parameters including Reference Signal Received Power (RSRP) and Reference Signal Received Quality (Reference Signal Received Quality). At least one of parameters such as RSRQ and Received Signal Strength Indicator (RSSI). The SS-block-measurement parameters described below are described by taking SS-block-RSRP as an example, and other parameters are similar. The unit of SS-block-RSRP is decibel milliwatts (dBm).

The number of the SS-block-RSRPs may be the same as the number of the multiple beams, that is, one beam corresponds to one SS-block-RSRP, and one may be one, that is, multiple SS-blocks corresponding to multiple beams. - RSRP is calculated to obtain an SS-block-RSRP; or N (less than the number of the plurality of beams), that is, N SSs are selected from a plurality of SS-block-RSRPs corresponding to the plurality of beams. block-RSRP. The specific number of SS-block-RSRPs is determined on a case-by-case basis.

If the number of the SS-block-RSRPs is one, the user equipment may perform average calculation on multiple SS-block-RSRPs corresponding to the multiple beams to obtain a first average measurement parameter, where the multiple SS- The number of block-RSRPs is the same as the number of the multiple beams, and the first average measurement parameter is determined as the SS-block-RSRP; the user equipment may also sort the multiple beams in chronological order. And for the first P (from the first to the Pth) beams (for example, the first P Orthogonal Frequency Division Multiplex (OFDM) symbols) corresponding to the P SS-block-RSRPs Performing an average calculation to obtain a second average measurement parameter, and determining the second average measurement parameter as the SS-block-RSRP; the user equipment may further multiple SS-block-RSRP corresponding to the multiple beams The Q SS-block-RSRPs corresponding to the Q beams in the preset time position are averaged to obtain a third average measurement parameter, and the third average measurement parameter is determined as the SS-block-RSRP, where The specific location of the preset time position is not limited herein.

Step S104: The user equipment generates a cell level measurement parameter according to the beam measurement parameter.

Specifically, the user equipment generates a cell-level (in English, but not limited to, a cell-level) measurement parameter according to the beam measurement parameter. Taking the RSRP as an example, the user equipment generates a cell according to the SS-block-RSRP. level-RSRP. The number of cell-level-RSRPs may be different for different numbers of the SS-block-RSRPs.

In a possible implementation manner, the number of the SS-block-RSRPs is the same as the number of the multiple beams, and the number of the cell-level-RSRPs is one. At this time, the network device generates the cell-level-RSRP according to multiple SS-block-RSRPs corresponding to the multiple beams. Optionally, the network device performs average calculation on the multiple SS-block-RSRPs corresponding to the multiple beams to obtain a first average measurement parameter, and determines the first average measurement parameter as the cell-level- RSRP. Optionally, the network device performs a sorting of the plurality of SS-block-RSRPs corresponding to the multiple beams, and sorts the top N (from the first to the Nth) SSs. The -block-RSRP performs an average calculation to obtain a second average measurement parameter, and determines the second average measurement parameter as the cell-level-RSRP. The N is smaller than the number of the multiple beams, and the specific number is not limited herein. Optionally, the network device acquires an SS-block-RSRP that exceeds a preset threshold, and performs average calculation on the SS-block-RSRP to obtain a third average measurement parameter, and determines the third average measurement parameter as Said cell-level-RSRP. The specific number of the preset thresholds is not limited herein. Optionally, the network device acquires an optimal SS-block-RSRP of the plurality of SS-block-RSRPs corresponding to the multiple beams, and determines the optimal SS-block-RSRP as the cell- level-RSRP, the best SS-block-RSRP may be the largest SS-block-RSRP, or may be the same beam, the SS-block-RSRP with the smallest gap from the last measured SS-block-RSRP, that is, stable The best SS-block-RSRP.

In a possible implementation manner, the number of the SS-block-RSRP is the same as the number of the multiple beams, and the number of the cell-level-RSRP is the same as the number of the multiple beams, that is, the The cell-level-RSRP includes the SS-block-RSRP corresponding to each of the beams.

In a possible implementation manner, the number of the cell-level-RSRPs is M, including M SS-block-RSRPs, and the value of M is smaller than the number of the multiple beams. The selection rules of the M SS-block-RSRPs are not limited herein. For example, the plurality of SS-block-RSRPs corresponding to the multiple beams may be sorted in the order of the top M (from the first to the first). M) SS-block-RSRP, which may also be M SS-block-RSRP corresponding to M odd or even beams in the multiple beams.

In a possible implementation, the number of the cell-level-RSRPs is one, that is, the best SS-block-RSRP among the multiple SS-block-RSRPs corresponding to the multiple beams, the most The best SS-block-RSRP can be the largest SS-block-RSRP, or the SS-block-RSRP with the smallest gap from the last measured SS-block-RSRP, which is the SS-block with the best stability. -RSRP.

Step S105: The user equipment sends the cell level measurement parameter. Optionally, the user equipment sends the cell level measurement parameter to the network device.

Optionally, the user equipment may send the cell level measurement parameter to the network device by layer 3 (Layer 3, L3) signaling. The L3 signaling may be a measurement report.

Although the cell-level-RSRP may include multiple SS-block-RSRPs corresponding to the multiple beams, and may also include M SS-block-RSRPs, but the cell-level-RSRP is carried in an L3 letter. It is sent in the order, so it can save the reporting overhead.

Optionally, the user equipment may perform filtering processing on the cell-level-RSRP before sending the cell-level-RSRP, for example, performing layer 3 filtering processing on the cell-level-RSRP, where the layer 3 The filtering formula can be: Fn=(1-a)*Fm+a*Mn, where Mn is the current measured value, Fm is the previously filtered value, Fn is the filtered value, and a is the filtering coefficient.

Step S106: The network device receives the cell level measurement parameter; optionally, the network device receives the cell level measurement parameter sent by the user equipment;

Optionally, the cell level measurement parameter may be used for handover or reselection between cells. When receiving the cell-level-RSRP reported by the user equipment, the network device may determine, according to the cell-level-RSRP, whether the user equipment needs to perform cell handover or reselection. If the user equipment is in the connected state, the network device determines whether the user equipment needs to perform cell handover; if the user equipment is in an idle state, the network device determines whether the user equipment needs to perform cell reselection. . The method for determining, by the network device, whether the user equipment needs to perform cell handover or reselection according to the cell-level-RSRP is not limited herein.

In the method described in FIG. 3, by measuring the measurement signals corresponding to each of the plurality of beams, the measurement reporting of the multiple beams in the NR system is implemented, and reporting is not necessary for each beam, which can save reporting overhead. .

Steps S103 to S105 in the embodiment shown in FIG. 3 are described in three manners. Optionally, the measurement signal includes the synchronization signal as an example.
