Alternatively, for CA technology, the terminal may communicate with the network device based on multiple carriers, for NR-DC technology, the terminal may connect with the network device through multiple cells, e.g., the terminal may connect to the network device through a primary cell, a primary secondary cell, or a secondary cell. Optionally, when the terminal communicates based on the CA technology and the NR-DC technology, the network device may also configure the terminal to perform L1 measurement, where the network device may configure the terminal to perform L1 measurement on multiple carriers in the CA currently used, or the network device may configure the terminal to perform L1 measurement on multiple cells currently accessed, respectively. Alternatively, the terminal typically uses a searcher (searcher) in the terminal to measure the carriers and/or cells. However, the number of searchers in the terminal is limited, and when the network device configures the terminal to perform L1 measurement on multiple carriers and/or multiple cells, if the number of carriers to perform L1 measurement and/or the number of cells to perform L1 measurement are greater than the number of searchers, how the terminal specifically performs L1 measurement on multiple carriers and/or multiple cells is a technical problem to be solved.

Fig. 2A is an interactive schematic diagram of a measurement method shown according to an embodiment of the disclosure. As shown in fig. 2A, embodiments of the present disclosure relate to a measurement method for a communication system 100, the method comprising:

step 2101, the network device sends a first configuration to the terminal, which may be used to configure the terminal to make L1 measurements for a plurality of cells or a plurality of frequency bands.

Alternatively, the network device may be a 5G network device, for example, a New Radio (NR) base station, an NR TRP, an NR node, and so on.

Alternatively, the method of embodiments of the present disclosure may be applicable to the following communication scenarios: an EN-DC scene, an NE-DC scene, an independent networking (SA) scene and an NR-DC scene.

Optionally, the EN-DC, i.e. the LTE-NR DC, comprises two network devices, namely an LTE network device and an NR network device, where the LTE network device is a primary node and the NR network device is a secondary node.

Optionally, the NE-DC, i.e. the NR-LTE DC, comprises two network devices, namely an LTE network device and an NR network device, wherein the NR network device is a primary node and the LTE network device is a secondary node.

Alternatively, the NR-DC, i.e. NR-NR DC, comprises two NR network devices, both the primary node and the secondary node being NR network devices.

Optionally, the primary node includes a primary cell and at least one secondary cell, and the secondary node may include a primary secondary cell and at least one secondary cell, where the terminal may access the at least one cell to communicate with a corresponding network device.

Optionally, the SA includes an NR network device, where the NR network device includes a primary cell and a plurality of secondary cells, and the terminal may access at least one cell to communicate with the NR network device in the SA.

Optionally, in some embodiments, the L1 measurement described above may include at least one of:

performing L1-reference signal received power (Reference Signal Receiving Power, RSRP) measurements on the reference signal;

l1-signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) measurements are made on the reference signal.

Optionally, the reference signal may include at least one of:

a synchronization signal block (synchronization signal block, SSB);

channel state information reference signal (CSI-RS).

Optionally, the case of the above-mentioned first configuration for configuring the terminal to perform L1 measurement on the plurality of cells may include at least one of the following, for example:

The first configuration is used for configuring the terminal to perform L1 measurement on the main cell and the plurality of auxiliary cells;

the first configuration is used for configuring the terminal to perform L1 measurement on the primary and secondary cells and the multiple secondary cells.

Optionally, the case where the first configuration is used to configure the terminal to perform L1 measurement on the plurality of frequency bands may include, for example: the first configuration is used for configuring the terminal to perform L1 measurement on one cell on each of a plurality of frequency bands, for example, there are two cells on the frequency band #1, namely, cell #1 and cell #2; there are three cells on band #1, cell #3, cell #4 and cell #5 respectively, and when the first configuration is used to configure the terminal to perform L1 measurement on cell #1 on band #1 and cell #3 on band #2 respectively, the first configuration is considered to be used to configure the terminal to perform L1 measurement on multiple bands. At this time, the total number of frequency bands required to perform the L1 measurement is equal to the total number of cells required to perform the L1 measurement.

Step 2102, the terminal and/or the network device determine a measurement mode when the terminal performs L1 measurement on a plurality of cells or a plurality of frequency bands based on the first unit number in the terminal.

Optionally, a first unit may be included in the terminal, where the first unit may be configured to perform measurements on a cell or a frequency band, such as performing L1 measurements, L3 measurements, etc., and optionally the first unit may be a searcher (searcher).

Alternatively, the above-mentioned "determining the measurement mode when the terminal performs the L1 measurement on the plurality of cells based on the first unit number in the terminal" may include: when at least two first units are included in the terminal, it is determined that one of the first units is used for L1 measurement on the primary cell or the primary and secondary cells, and the remaining first units are used for L1 measurement on the plurality of secondary cells, for example, one or more secondary cells may be respectively allocated to each of the remaining first units, so that each of the remaining first units is respectively used for L1 measurement on one or more secondary cells.

For example, assuming that the terminal includes two first units, when the network device configures the terminal to perform L1 measurement on a plurality of cells, the terminal may determine that one of the two first units is used for L1 measurement on a primary cell or a primary secondary cell, and the other of the two first units is used for L1 measurement on a plurality of secondary cells.

Optionally, in some embodiments, when one first unit is used to perform L1 measurement on a plurality of cells, the terminal may perform L1 measurement on a plurality of cells sequentially and respectively using the one first unit, and optionally, "performing L1 measurement on a plurality of cells sequentially and respectively using the one first unit" herein may include: assume that a first unit is used for L1 measurements on two cells: cell #1 and cell #3 may first perform L1 measurement on cell #1 by using the first unit, and then perform L1 measurement on cell #3 by using the first unit after measurement is completed; or, the first unit is used for performing the L1 measurement on the cell #3, and after the measurement is completed, the first unit is used for performing the L1 measurement on the cell # 1.

Alternatively, the above-mentioned "determining the measurement mode when the terminal performs the L1 measurement on the plurality of frequency bands based on the first unit number in the terminal" may include: when at least two first units are included in the terminal, it is determined that one of the first units is used for performing L1 measurement on a frequency band corresponding to the primary cell or the primary and secondary cells, and the remaining first units are used for performing L1 measurement on frequency bands corresponding to the secondary cells, for example, one or more frequency bands may be respectively allocated to each of the remaining first units, so that each of the remaining first units is respectively used for performing L1 measurement on one or more frequency bands.

For example, assuming that the terminal includes two first units, when the network device configures the terminal to perform L1 measurement on a plurality of frequency bands, the terminal may determine that one of the two first units is used to perform L1 measurement on a frequency band corresponding to a primary cell or a primary and secondary cell, and the other of the two first units is used to perform L1 measurement on a frequency band corresponding to a plurality of secondary cells, respectively.

Optionally, in some embodiments, when one first unit is used to perform L1 measurement on a plurality of frequency bands, the terminal may perform L1 measurement on the plurality of frequency bands sequentially with the one first unit, and optionally, "performing L1 measurement on the plurality of frequency bands sequentially with the one first unit" herein may include: assume that a first unit is used to make L1 measurements for two frequency bands: if the frequency bands #1 and #3 are the frequency band #1, the first unit may perform the L1 measurement on the frequency band #1, and if the measurement is completed, the first unit may perform the L1 measurement on the frequency band # 3; alternatively, the first unit is used to perform the L1 measurement on the band #3, and when the measurement is completed, the first unit is used to perform the L1 measurement on the band # 1.

Step 2103, the terminal performs L1 measurement on a plurality of cells or a plurality of frequency bands based on the determined measurement method.

Alternatively, the terminal may perform L1 measurements on multiple cells or multiple frequency bands based on the measurement manners determined in step 2102, which may be described with reference to the above embodiments.

Step 2104, the terminal and/or the network device determines a measurement time for the L1 measurement based on a total number of cells needed to perform the L1 measurement or a total number of frequency bands needed to perform the L1 measurement.

Alternatively, taking the case that the terminal includes two first units as an example, the above-mentioned "total number of cells required to perform L1 measurement, total number of frequency bands required to perform L1 measurement" will be described in detail.

Alternatively, when two first units of the terminal perform L1 measurement in parallel in synchronization, at this time, since one first unit is only used for performing L1 measurement on the primary cell or the primary and secondary cells and the other first unit is used for performing L1 measurement on the plurality of secondary cells, the time required for the measurement of the other first unit is longer, and at this time, if the two first units perform L1 measurement in parallel in synchronization, the total measurement time required for L1 measurement should be the measurement time required for the longer measurement time required in the two first units, that is, the total measurement time required for L1 measurement is: the time required for the above-mentioned another first unit to sequentially perform L1 measurements on the plurality of secondary cells, respectively, and at this time, the total number of cells required to perform L1 measurements may be understood as: the total number of cells needed to perform the L1 measurement by the further first unit; the total number of frequency bands needed to perform the L1 measurement can be understood as: the total number of frequency bands for which the L1 measurement needs to be performed by the further first unit. On this basis, when the communication scene is EN-DC or NE-DC or SA, the total number of cells required to perform L1 measurement is the total number of secondary cells required to perform L1 measurement in a 5G node (i.e., the aforementioned 5G network device) in EN-DC scene or NE-DC scene or SA scene, and the total number of frequency bands required to perform L1 measurement is the total number of frequency bands corresponding to secondary cells required to perform L1 measurement in a 5G node in EN-DC scene or NE-DC scene or SA scene; when the communication scene is NR-DC, the total number of cells needing to perform L1 measurement is equal to the total number of secondary cells needing to perform L1 measurement in two 5G nodes in the NR-DC scene, and the total number of frequency bands needing to perform L1 measurement is equal to the total number of frequency bands corresponding to the secondary cells needing to perform L1 measurement in two 5G nodes in the NR-DC scene.

For example, assuming that the total number of secondary cells in the 5G node that need to perform L1 measurement or the total number of frequency bands corresponding to secondary cells in the 5G node that need to perform L1 measurement is Z, when the communication scenario is EN-DC or NE-DC or SA, the total number of cells that need to perform L1 measurement or the total number of frequency bands that need to perform L1 measurement is: z. When the communication scenario is NR-DC, the total number of cells required to perform L1 measurement or the total number of frequency bands required to perform L1 measurement is: 2 XZ.

Alternatively, the above-mentioned 5G node may be, for example: gnode B.

Alternatively, when two first units of the terminal do not perform the L1 measurement in parallel (for example, when one first unit starts to perform the L1 measurement after the corresponding L1 measurement is completed, the other first unit starts to perform the L1 measurement), the total measurement time required for the L1 measurement is the sum of the measurement times required for the two first units, and at this time, the total number of cells required to perform the L1 measurement may be understood as: the total number of all cells required to perform the L1 measurement, and the total number of frequency bands required to perform the L1 measurement can be understood as: the total number of all bands for which L1 measurements need to be performed; on this basis, when the communication scenario is EN-DC or NE-DC or SA, the total number of cells required to perform L1 measurement is the total number of all cells required to perform L1 measurement in a 5G node (i.e., the aforementioned 5G network device) in EN-DC scenario or NE-DC scenario or SA scenario, and the total number of frequency bands required to perform L1 measurement is the total number of frequency bands corresponding to all cells required to perform L1 measurement in a 5G node in EN-DC scenario or NE-DC scenario or SA scenario; when the communication scene is NR-DC, the total number of cells required to perform L1 measurement is equal to the total number of all cells required to perform L1 measurement in the two 5G nodes in the NR-DC scene, and the total number of frequency bands required to perform L1 measurement is equal to the total number of frequency bands corresponding to all cells required to perform L1 measurement in the two 5G nodes in the NR-DC scene. Alternatively, all cells that need to perform L1 measurements may include: the number of primary and secondary cells needed to perform the L1 measurement and/or the number of primary and secondary cells needed to perform the L1 measurement.

By way of example, assuming that the total number of all cells in the 5G node that need to perform L1 measurement or the total number of bands corresponding to all cells in the 5G node that need to perform L1 measurement is Z, when the communication scenario is EN-DC or NE-DC or SA, the total number of cells that need to perform L1 measurement or the total number of bands that need to perform L1 measurement is: z, when the communication scenario is NR-DC, the total number of cells required to perform L1 measurement or the total number of frequency bands required to perform L1 measurement is: 2 XZ.

Alternatively, after determining "the total number of cells required to perform the L1 measurement, and the total number of frequency bands required to perform the L1 measurement", the terminal and/or the network device may determine the measurement time of the L1 measurement based on the total number of cells required to perform the L1 measurement or the total number of frequency bands required to perform the L1 measurement. The method for determining the measurement time may be different when the frequency band, the L1 measurement content (e.g., L1-RSRP measurement or L1-SINR measurement), or the reference signal is different when the L1 measurement is performed.

The following is an exemplary description of the above method.

When the UE makes L1-RSRP measurements for multiple scells, the UE cannot make measurements for all scells in parallel. The UE has only two searchers. Due to the limitations of two searchers, the measurement time needs to be scaled for the CA or NR-DC case. The UE will use one of the two searchers for PCell or PSCell measurements while the other searcher will be shared among different SCell measurements.

If one searcher were to be shared between different scells, the L1-RSRP measurement period for each SCell would be scaled (extended).

There are two scale factor design options:

1. the searcher is shared by all SCells. The scale factor value will be the number of SCells.

2. The searcher is shared among multiple frequency bands in which the UE performs L1-RSRP. The UE only needs to perform L1-RSRP on one frequency band for one cell. The scale factor will be the number of frequency bands.

According to these two options, the SSB-based L1-RSRP measurement period needs to be scaled:

for SSB-based L1-RSRP measurements, the measurement period is:

for each SSB resource configured for SCell

PL 1-rsrp=z at EN-DC or NE-DC or SA.

PL 1-rsrp= 2*Z at NR-DC.

-wherein Z is the number of bands in which the UE performs L1-RSRP only for scells.

Or Z is the number of cells the UE is performing L1-RSRP.

Table 9.5.4.1-2:Measurement period T _{L1-RSRP_Measurement_Period_SSB} for FR2

For CSI-RS based L1-RSRP:

for each CSI-RS resource configured for SCell

PL 1-rsrp=z at EN-DC or NE-DC or SA.

PL 1-rsrp= 2*Z at NR-DC.

Or Z is the number of cells the UE is performing L1-RSRP.

/>

Furthermore, the L1-SINR measurement period requirement also needs to be adjusted for CA or NR-DC schemes.

For CSI-RS based L1-SINR measurements, the measurement period will be:

for each CSI-RS resource configured for SCell

PL 1-sinr=z at EN-DC or NE-DC or SA.

PL 1-sinr= 2*Z at NR-DC.

-wherein Z is the number of frequency bands in which the UE performs L1-SINR only for SCell.

Or Z is the number of cells the UE is performing L1-SINR.

PL 1-sinr=z at EN-DC or NE-DC or SA.

Or Z is the number of cells the UE is performing L1-SINR.
