In a first aspect, an embodiment of the present disclosure proposes a communication method performed by a network device, the method comprising:

In the above embodiment, the network device may determine whether to reuse the carrier measurement results corresponding to the different carriers in the inter-band carrier aggregation with each other, or alternatively, when the network device determines that the carrier measurement results corresponding to the different carriers in the inter-band carrier aggregation may be overlapped with each other, the network device may perform carrier measurement configuration on a part of the carriers in the inter-band carrier aggregation, and may not perform carrier measurement configuration on other carriers in the inter-band carrier aggregation, and the terminal may also perform carrier measurement on a part of the carriers in the carrier aggregation, without performing carrier measurement on other carriers, thereby greatly saving power consumption of the terminal and the network device. On the other hand, in the above embodiment, the network device determines whether to reuse the carrier measurement results corresponding to different carriers in the inter-band carrier aggregation with each other according to whether the terminal satisfies the first condition, where the first condition is used to indicate: the conditions that need to be met when the carrier measurement results between different inter-band carriers can be mutually overlapped can be known, so that in the embodiment of the disclosure, when the terminal meets the conditions that the carrier measurement results between different inter-band carriers can be mutually overlapped, the carrier measurement results corresponding to different inter-band carriers can be mutually reused, and at the moment, when the carrier measurement results corresponding to different carriers are mutually overlapped, the accuracy of carrier measurement cannot be affected. The embodiment of the disclosure not only can save the power consumption of the terminal and the network equipment, but also can ensure the precision of carrier measurement.

With reference to some embodiments of the first aspect, in some embodiments, the method further comprises at least one of:

determining that the terminal meets the first condition, and reusing a carrier measurement result corresponding to the first carrier for the second carrier;

and determining that the terminal does not meet the first condition, and sending a first configuration to the terminal, wherein the first configuration is used for configuring the terminal to perform carrier measurement on the second carrier.

In the above embodiment, when the network device determines that the terminal meets the first condition, the network device does not perform carrier measurement configuration on the terminal, but directly re-uses the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier, so that power consumption of the terminal and the network device can be saved, and carrier measurement accuracy can be ensured. And when the network equipment determines that the terminal does not meet the first condition, the network equipment sends a first configuration to the terminal, wherein the first configuration is used for configuring the terminal to perform carrier measurement on the second carrier, so that when the carrier measurement results of different carriers in inter-band carrier aggregation cannot be reused, the terminal can be ensured to successfully perform carrier measurement on the second carrier, and smooth execution of carrier measurement is ensured.

With reference to some embodiments of the first aspect, in some embodiments, the first condition includes at least one of:

the difference between the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier is smaller than a first threshold value;

the terminal is in a first state, and the moving speed of the terminal in the first state is smaller than a second threshold value.

In the above embodiment, the specific content of the first condition is defined, so that the network device can successfully determine whether the terminal meets the first condition based on the content of the first condition, and thus the network device can further determine whether to reuse the carrier measurement result corresponding to the first carrier for the second carrier, so as to achieve the purpose of saving electricity and energy.

With reference to some embodiments of the first aspect, in some embodiments, the first condition includes the terminal being in a first state, and determining whether the terminal is in the first state includes:

receiving a first signaling reported by the terminal, wherein the first signaling is used for indicating the moving speed of the terminal;

and the difference between the carrier wave measuring results corresponding to the first carrier waves at different moments is larger than or equal to a third threshold value, and the terminal is determined not to be in the first state.

In the above embodiment, a method for determining, by the network device, whether the terminal meets the first condition is provided, so that the network device can successfully determine, based on the method, whether the terminal meets the first condition, and therefore, the network device can further determine whether to reuse the carrier measurement result corresponding to the first carrier for the second carrier, so as to achieve the purpose of power saving and energy saving.

With reference to some embodiments of the first aspect, in some embodiments, the first carrier is a carrier that has been configured for carrier measurement, and the second carrier is a carrier that has not been configured for carrier measurement.

In the above embodiment, the first carrier is defined as a carrier that has been configured for carrier measurement, and the second carrier is defined as a carrier that has not been configured for carrier measurement, so it can be known that, in the present disclosure, when the network device determines that the terminal satisfies the first condition, the network device re-uses the carrier measurement result of the first carrier that has been configured for carrier measurement to the second carrier that has not been configured for carrier measurement, and at this time, the network device may not need to perform any carrier measurement configuration on the second carrier, and the terminal also does not need to perform carrier measurement and reporting on the second carrier, so signaling overhead may be saved, and power consumption of the terminal and the network device may be reduced.

With reference to some embodiments of the first aspect, in some embodiments, the carrier measurement includes at least one of:

layer 1L1 reference signal received power RSRP measurement;

layer 3l3 RSRP measurement.

In the above embodiment, when the network device determines that the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation is not reused for the second carrier, the network device may send the first configuration to the terminal to configure the terminal to perform carrier measurement on the second carrier, in other words, when the network device determines that the carrier measurement result corresponding to the first carrier is reused for the second carrier, the first configuration is not sent to the terminal, and thus, when the network device determines that the carrier measurement results corresponding to different carriers in the inter-band carrier aggregation can be mutually reused, the network device may not perform carrier measurement configuration on a part of carriers in the inter-band carrier aggregation, and the terminal may not need to perform carrier measurement on a part of carriers, thereby greatly saving power consumption of the terminal and the network device. On the other hand, in the above embodiment, when the terminal satisfies the condition that the carrier measurement results between the different inter-band carriers can be mutually reused, the carrier measurement results corresponding to the different inter-band carriers are mutually reused, and at this time, the accuracy of the carrier measurement is not affected when the carrier measurement results corresponding to the different inter-band carriers are mutually reused.

Fig. 2A1 is an interactive schematic diagram of a communication method shown according to an embodiment of the disclosure. As shown in fig. 2A1, embodiments of the present disclosure relate to a communication method for a communication system 100, the method including:

step 2101, the network device sends a second configuration to the terminal, where the second configuration is used to configure the terminal to perform carrier measurement on the first carrier.

Alternatively, the terminal may receive the second configuration.

Optionally, the second configuration may be used to configure the terminal to perform carrier measurement on the first carrier in inter-band carrier aggregation, and optionally, different carriers used for carrier aggregation respectively belong to different frequency bands (bands) during inter-band carrier aggregation. The first carrier may be any carrier in inter-band carrier aggregation. The first carrier may be, for example, a carrier corresponding to a primary cell or a primary secondary cell, or may be, for example, a carrier corresponding to a secondary cell.

Optionally, the second configuration may comprise, for example, at least one of:

an object to be measured on the first carrier, which object to be measured may be, for example, a reference signal, such as: a synchronization signal block (synchronization signal block, SSB), and/or a Channel state information reference signal (CSI-RS), etc.;

the carrier measurement content may include, for example, at least one of a layer 1reference signal received power (layer 1Reference Signal Receiving Power,L1-RSRP) measurement, an L3-RSRP measurement.

Alternatively, the foregoing is merely an example, and other contents may be included in the second configuration, which is not limited by the present disclosure.

In some embodiments, terms of "component carrier (component carrier, CC)", "cell", "frequency carrier (frequency carrier)", "carrier frequency (carrier frequency)", and the like may be interchanged.

In some embodiments, terms such as "send," "transmit," "report," "send," "transmit," "bi-directional," "send and/or receive," and the like may be used interchangeably.

In some embodiments, "acquire," "obtain," "receive," "transmit," "bi-directional transmit," "send and/or receive" may be used interchangeably and may be interpreted as receiving from other principals, acquiring from protocols, acquiring from higher layers, processing itself, autonomous implementation, etc.

Step 2102, the terminal performs carrier measurement on the first carrier based on the second configuration.

Optionally, the terminal may perform L1-RSRP measurement and/or L3-RSRP measurement on the object to be measured on the first carrier based on the second configuration to obtain a carrier measurement result corresponding to the first carrier,

step 2103, the terminal reports the carrier measurement result corresponding to the first carrier to the network device.

Step 2104, the network device determines whether to reuse a carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier according to whether the terminal satisfies the first condition.

Optionally, the second carrier is a carrier in which no carrier measurement configuration is performed in inter-band carrier aggregation. The second carrier may be, for example, a carrier corresponding to the secondary cell.

Alternatively, the first condition may be used to indicate: the carrier measurement results between different inter-band carriers can overlap each other under the condition that needs to be satisfied. Alternatively, the "different inter-band carriers" herein may be understood as, for example: different carriers in the inter-band carrier aggregation.

Optionally, the first condition may include at least one of:

The terminal is in a first state in which the movement speed of the terminal is less than a second threshold, alternatively, the first state may be understood as, for example: a low shift speed terminal (low mobility status).

Optionally, in some embodiments, when the network device determines that the terminal satisfies the first condition, the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation may be reused for the second carrier.

Optionally, in some embodiments, when the network device determines that the terminal does not meet the first condition, it is determined that a carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation is not available for reuse for the second carrier.

Optionally, the principle of why the carrier measurements between different inter-band carriers are re-usable with each other when the difference between the different inter-band carriers is smaller than the first threshold and/or when the terminal is in the first state is described below by taking the carrier measurement of "L1-RSRP" as an example.

Alternatively, the L1-RSRP may provide instantaneous channel quality, and in a channel fast fading model, doppler shift may affect the channel model and the corresponding received signal power level (L1-RSRP). Optionally, the doppler shift is dependent on the carrier frequency and the terminal speed. Thus, if a network device attempts to reuse the L1-RSRP measurement of one carrier for another carrier, two factors need to be considered:

1. A frequency gap between the two carriers;

2. terminal speed.

Alternatively, for inter-band carrier aggregation under FR1, there are several band combinations. For certain frequency band combinations, the frequencies between different inter-band carriers are close to each other, e.g., 800MHz (megahertz) and 900MHz. While for some other band combinations the frequencies between different inter-band carriers are far apart, e.g. 800MHz and 1.5/2.5/3.5 GHz. Furthermore, the terminal may have different speeds, e.g. 5km/h (kilometers per hour) or 30km/h, both the frequency gap between the two carriers and the different speeds may have an impact on the carrier measurements of the L1-RSRP on the two carriers. Simulation results for different band combinations are provided below. Assuming that 4 inter-band carriers are provided, the center frequencies are 800MHz, 900MHz, 1.5GHz and 2.5GHz respectively, if the speeds of the terminals are all 5km/h. Fig. 2A2 is an L1-RSRP gap between two carriers of different frequencies in a low mobility state, as illustrated in accordance with an embodiment of the present disclosure. As shown in fig. 2A2, when the frequency gap between two carriers increases, the gap between L1-RSRP also increases. Taking 800MHz and 900MHz as examples, the L1-RSRP gap is small, e.g., less than 1dB in 90% of cases. It is reasonable to replace the 900MHz carrier with the L1-RSRP of the 800MHz carrier. However, if the band combination is 800MHz and 1.5G/2.5G Hz, the gap between L1-RSRP increases to 2-3 dB, then it is not appropriate to reuse the L1-RSRP of the 800MHz carrier for the 1.5G/2.5G Hz carrier.

Optionally, fig. 2A3 shows an L1-RSRP gap between two carriers of 800MHz and 900MHz at terminal speeds of 5km/h and 30km/h according to an embodiment of the present disclosure, optionally, doppler spread increases when the terminal moves faster, and in fig. 2A3, the RSRP gap between 800MHz and 900MHz is smaller when the terminal is in a low-movement state (i.e., 5 km/h). However, when the terminal speed increases from 5km/h to 30km/h, the RSRP gap between the two carriers increases from 1dB to 3dB or 4dB. This means that RSRP between different carriers can be reused with each other only when the terminal is in a low mobility state.

Alternatively, fig. 2A4 is an L1-RSRP gap between two carriers of 800MHz and 1.5GHz at terminal moving speeds of 5km/h and 30km/h, which is shown in fig. 2A4, and the L1-RSRP gap between two carriers of 800MHz and 1.5GHz is further enlarged due to the larger terminal moving speed.

It can be seen that the carrier frequency differences between different carriers are smaller and/or the differences in carrier measurement results between different carriers are smaller when the movement speed of the terminal is smaller, so that the carriers can be reused. Thus, in one embodiment of the present disclosure, the first condition described above may be made to include at least one of:

the terminal is in a first state.

Optionally, in some embodiments, the network device needs to determine whether the terminal satisfies the first condition, and determine to reuse the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier when the network device determines that the terminal satisfies the first condition, and determine not to reuse the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier when the network device determines that the terminal does not satisfy the first condition.

Optionally, since the carrier related parameter of the terminal is configured by the network device, the network device may directly know the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier, and then the network device may directly determine whether the difference between the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier is less than the first threshold.

Optionally, when the first condition includes: the method for the network device to determine whether the terminal is in the first state when the terminal is in the first state may include at least one of:

First kind: the first signaling is reported by the terminal to the network device, the first signaling may be used to indicate a movement speed of the terminal, and the network device may determine whether the terminal is in the first state based on the movement speed of the terminal indicated by the first signaling.

Alternatively, the terminal may autonomously measure its movement speed and report the first signaling to the network device periodically or aperiodically based on the movement speed measured by the terminal. Alternatively, the first signaling may be an existing signaling or a newly designed signaling, which is not limited in this disclosure.

Second kind: the network device calculates the moving speed of the terminal based on the uplink signal sent by the terminal, and determines whether the terminal is in the first state based on the moving speed of the terminal.

Optionally, the uplink signal may be, for example, SRS and/or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). Alternatively, the uplink signal may be sent by the terminal through the first carrier.

Alternatively, in some embodiments, terms such as "uplink," "physical uplink," and the like may be replaced with each other, terms such as "downlink," "physical downlink," and the like may be replaced with each other, terms such as "side," "side link," "side communication," "side link," "direct link," and the like may be replaced with each other.

Third kind: the network equipment receives carrier measurement results corresponding to first carriers respectively reported by a terminal at least two different moments, and when the difference between the carrier measurement results corresponding to the first carriers at different moments is smaller than a third threshold value, the terminal is determined to be in a first state; and when the difference between the carrier wave measurement results corresponding to the first carrier waves at different moments is larger than or equal to a third threshold value, determining that the terminal is not in the first state. Or when the difference between the carrier wave measurement results corresponding to the first carrier waves at different moments is smaller than or equal to a third threshold value, determining that the terminal is in a first state; and when the difference between the carrier wave measurement results corresponding to the first carrier waves at different moments is larger than a third threshold value, determining that the terminal is not in the first state.

In step 2105, the network device determines that the terminal satisfies a first condition, and reuses a carrier measurement result corresponding to the first carrier to the second carrier.

Optionally, when the network device determines that the terminal meets the first condition, it indicates that the carrier measurement results between different inter-band carriers can be reused, at this time, the network device may not configure carrier measurement for the second carrier, but may directly reuse the carrier measurement result corresponding to the first carrier for the second carrier, so that the terminal may not need to perform carrier measurement and reporting for the second carrier, signaling interaction between the terminal and the network device may be saved, communication overhead may be reduced, power consumption and power of the terminal and the network device may be saved, and the purpose of saving electricity may be achieved.

Alternatively, the steps 2104-2105 may be exchanged with the steps 2101-2103 for performing the sequence, e.g., steps 2104-2105 may be performed first, followed by steps 2101-2103; alternatively, steps 2104-2105 may be performed concurrently with steps 2101-2103 described above, or steps 2104-2105 may be performed interspersed with steps 2101-2103 described above, e.g., steps 2101 may be performed first, steps 2104-2105 may be performed second, step 2102 and step 2103 may be performed second, or steps 2104 may be performed first, steps 2101-2103 may be performed second, and step 2105 may be performed second. The present disclosure is not limited in this regard.

The communication method according to the embodiments of the present disclosure may include at least one of steps 2101 to 2105. For example, step 2101 may be implemented as a stand-alone embodiment, step 2102 may be implemented as a stand-alone embodiment, and step 2101+2102 may be implemented as a stand-alone embodiment, but is not limited thereto.

In this embodiment mode or example, the steps may be independently, arbitrarily combined, or exchanged in order, and the alternative modes or examples may be arbitrarily combined, and may be arbitrarily combined with any steps of other embodiment modes or other examples without contradiction.

The following is an exemplary description of the above method.

L1-RSRP

In the current inter-band FR1 inter-band CA, the NW (i.e., the aforementioned network device) will configure and issue reference signals for the PCell and scell. The UE (i.e. the aforementioned terminal) will perform L1-RSRP or L3-RSRP measurements on the PCell and SCell, respectively.

Optionally, the L1-RSRP provides instant channel quality. In the channel fast fading model, the doppler shift affects the channel model and the corresponding received signal power level (L1-RSRP). Taking the tap delay line model (Tapped Delay Line, TDL) model as an example, in the fast fading model, the doppler shifts are as follows:

doppler frequencyThe rate component depends on the angle of arrival (AOA, ZOA), and UT velocity vector having velocity v, azimuth angle of travel, φv, elevation angle, θv Is given by

The doppler shift depends on the carrier frequency and the UE speed. The angle of arrival of the rays also has an effect on doppler. However, the angles of arrival of the light rays for all carriers are the same, as is the case with co-located locations. We do not need to consider the effect of the angle of arrival difference.

Thus, if the base station attempts to reuse the L1-RSRP measurement of one carrier for another carrier for co-located inter-band FR1CA, two factors need to be considered:

1. frequency gap between two carriers

Ue speed and angle

For interband FR1CA, there are several band combinations. For certain band combinations, the two carriers of SCells are close to each other, e.g., 800MHz and 900 MHz. While for some other band combinations the two carriers are far apart, e.g. 800MHz and 1.5/2.5/3.5GHz. Furthermore, the UE may have different speeds, e.g. 5km/h or 30km/h

Both the frequency gap between the two carriers and the different speeds have an effect on the signal level on the two carriers.

Alternatively, simulation results for different band combinations are provided. Assuming 4 carriers, the center frequencies are 800MHz, 900MHz, 1.5GHz, 2.5GHz.

Optionally, the UE speed for all carriers is 5km/h. We compare L1-RSRP between different operators in low mobility state, as shown in fig. 2A2 above, optionally when the frequency gap between two carriers increases, the RSRP gap also increases. Taking 800MHz and 900MHz as examples, the RSRP gap is small, e.g. less than 1dB in 90% of cases. It is reasonable to replace the 900MHz carrier with the L1-RSRP of the 800MHz carrier. However, if the band combination is 800MHz and 1.5G/2.5G Hz, the RSRP gap increases to 2-3 dB. It is not appropriate to reuse the result for another SCell. Therefore, a frequency gap between two carriers needs to be defined for reuse.

Optionally, the L1-RSRP gap at different speeds is also simulated. In the above-described FIG. 2A3, the RSRP gap between 5km/h and 30km/h at 800MHz and 900MHz is compared.

Alternatively, the doppler spread may increase as the UE moves faster. The RSRP gap between 800MHz and 900MHz will increase. In fig. 1, the RSRP gap between 800MHz and 900MHz is small when in the low mobility state. However, as shown in fig. 2, when the UE speed increases from 5KM to 30KM, the RSRP gap between the two carriers increases from 1dB to 3dB or 4dB. This means that RSRP can only be reused in low mobility states. We also simulated RSRP differences between 800MHz and 1.5GHz at v=5 km/h and 30km/h, as shown in fig. 2A4 above.

This also shows that the RSRP gap between the two carriers will be further extended by the greater speed.

In summary, if the NW tries to reuse the L1-RSRP of one cell for another Scell in the inter-band FR1 CA, the applicability should consider two conditions:

1. the frequency gap is less than [ x ] Hz.

Ue in low mobility state

These two conditions may be used alone or in combination.

For low mobility states, there are several options to obtain information:

Option 1 the ue sends speed related information to the NW. Signaling designed for UE speed indication is required.

Option 2 nw calculates the mobility state of the UE from a certain UL signal.

Option 3 the ue sends two L1-RSRP reports to the NW in different time slots. If the RSRP gap between the two L1-RSRP reports is small, the NW will consider the UE to be in a low mobility state.

For frequency gap information, the NW will know this information when configuring CA.

The procedure for power saving is as follows:

if the frequency gap of two carriers in CA is less than X Hz,

if the UE is in low mobility state, the NW will not configure L1-RSRP measurements for one cell. The NW re-uses the L1-RSRP report of one carrier for another carrier. Both NW and UE will save power.

If the UE is not in low mobility state, the NW will configure L1-RSRP measurements for both cells.

Otherwise if the frequency separation of the two carriers in CA is greater than X Hz,

-NW will configure L1-RSRP measurements for both cells

L3-RSRP

For L3-RSRP measurements, the UE will perform time domain filtering based on the L1-RSRP measurements. Due to the averaging, the doppler effect can be reduced. Thus, for L3-RSRP measurements, there may be only a frequency gap threshold.

The procedure for power saving is as follows:

if the frequency gap of two carriers in CA is less than X Hz,

The NW will not configure the L3-RSRP measurement for one cell. The NW re-uses the L3-RSRP report of one carrier for another carrier. Both NW and UE will save power.

the NW will configure the L3-RSRP measurement for both cells.
