[0037] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0038] In a first aspect, an embodiment of the present disclosure provides a communication method, which is performed by a network device. The method includes:

[0039] Determine whether to reuse the carrier measurement result corresponding to the first carrier in inter-band carrier aggregation (ICA) for the second carrier based on whether the terminal meets the first condition; wherein the first condition is used to indicate: the conditions that must be met when the carrier measurement results between different inter-band carriers can be reused with each other.

[0040] In the above embodiment, the network device determines whether to reuse carrier measurement results corresponding to different carriers in inter-band carrier aggregation. Optionally, when the network device determines that carrier measurement results corresponding to different carriers in inter-band carrier aggregation can be reused, the network device can configure carrier measurement for some of the carriers in the inter-band carrier aggregation, but not for other carriers in the inter-band carrier aggregation. Furthermore, the terminal can also perform carrier measurement on some of the carriers in the carrier aggregation without performing carrier measurement on other carriers, thereby significantly 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 carrier measurement results corresponding to different carriers in inter-band carrier aggregation based on whether the terminal satisfies a first condition. The first condition is used to indicate the conditions that must be met for carrier measurement results between different inter-band carriers to be reused. Therefore, in the embodiment of the present disclosure, carrier measurement results corresponding to different inter-band carriers are reused only when the terminal satisfies the conditions for reusing carrier measurement results between different inter-band carriers. In this case, reusing carrier measurement results corresponding to different carriers does not affect the accuracy of carrier measurement. The embodiments of the present disclosure can not only save power consumption of terminals and network devices, but also ensure the accuracy of carrier measurement.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0042] Determining that the terminal meets the first condition, and reusing the carrier measurement result corresponding to the first carrier for the second carrier;

[0043] Determine that the terminal does not meet the first condition, and send a first configuration to the terminal, where the first configuration is used to configure the terminal to perform carrier measurement on the second carrier.

[0044] 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 reuses the carrier measurement result corresponding to the first carrier in inter-band carrier aggregation for the second carrier. This can save power consumption of the terminal and the network device, and ensure carrier measurement accuracy. Furthermore, when the network device determines that the terminal does not meet the first condition, the network device sends a first configuration to the terminal, which is used to configure the terminal to perform carrier measurement on the second carrier. Thus, 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, ensuring smooth execution of carrier measurement.

[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes at least one of the following:

[0046] A difference between a carrier frequency corresponding to the first carrier and a carrier frequency corresponding to the second carrier is less than a first threshold;

[0047] The terminal is in a first state, and in the first state, the moving speed of the terminal is less than a second threshold.

[0048] 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, so that the network device can further determine whether to reuse the carrier measurement result corresponding to the first carrier for the second carrier to achieve the purpose of saving power and energy.

[0049] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes that the terminal is in a first state, and determining whether the terminal is in the first state includes:

[0050] receiving a first signaling reported by the terminal, where the first signaling is used to indicate a moving speed of the terminal;

[0051] It is determined whether the terminal is in the first state based on a moving speed of the terminal.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes that the terminal is in a first state, and determining whether the terminal is in the first state includes:

[0053] Calculating a moving speed of the terminal based on an uplink signal sent by the terminal;

[0054] It is determined whether the terminal is in the first state based on a moving speed of the terminal.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes that the terminal is in a first state, and determining whether the terminal is in the first state includes:

[0056] receiving carrier measurement results corresponding to the first carrier reported by the terminal at at least two different times;

[0057] If a difference between carrier measurement results corresponding to the first carrier at different times is less than a third threshold, it is determined that the terminal is in the first state;

[0058] If a difference between carrier measurement results corresponding to the first carrier at different times is greater than or equal to a third threshold, it is determined that the terminal is not in the first state.

[0059] In the above embodiment, a method is provided for the network device to determine whether the terminal satisfies the first condition, so that the network device can successfully determine whether the terminal satisfies the first condition based on the method, and the network device can further determine whether to reuse the carrier measurement result corresponding to the first carrier for the second carrier to achieve the purpose of saving power and energy.

[0060] In combination with some embodiments of the first aspect, in some embodiments, the first carrier is a carrier for which carrier measurement configuration has been performed, and the second carrier is a carrier for which carrier measurement configuration has not been performed.

[0061] In the above embodiment, the first carrier is defined as a carrier for which carrier measurement has been configured, and the second carrier is defined as a carrier for which carrier measurement has not been configured. Therefore, it can be seen that in the present disclosure, when the network device determines that the terminal meets the first condition, the carrier measurement result of the first carrier for which carrier measurement has been configured is reused for the second carrier for which carrier measurement has not been configured. At this time, the network device does not need to perform any carrier measurement configuration on the second carrier, and the terminal does not need to perform carrier measurement and report on the second carrier, which can save signaling overhead and reduce power consumption of the terminal and the network device.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the carrier measurement includes at least one of the following:

[0063] Layer 1 L1 reference signal received power RSRP measurement;

[0064] Layer 3 L3 RSRP measurement.

[0065] In the above embodiment, the specific measurement content of the carrier measurement is defined, so that the terminal can successfully perform the carrier measurement based on the specific measurement content and successfully report the carrier measurement result.

[0066] In a second aspect, an embodiment of the present disclosure provides a communication method, which is performed by a terminal, and the method includes at least one of the following:

[0067] Receive a first configuration sent by a network device, where the first configuration is used to configure the terminal to perform carrier measurement on a second carrier; wherein the first configuration is configured to the terminal when the network device determines not to reuse the carrier measurement result corresponding to the first carrier in inter-band carrier aggregation for the second carrier; wherein the network device determines whether to reuse the carrier measurement result corresponding to the first carrier in inter-band carrier aggregation for the second carrier based on whether the terminal meets a first condition, where the first condition is used to indicate: conditions that must be met when carrier measurement results between different inter-band carriers can be reused with each other.

[0068] In the above embodiment, when the network device determines not to reuse the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier, the network device will send a 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 to reuse the carrier measurement result corresponding to the first carrier for the second carrier, the first configuration will not be sent to the terminal. Therefore, when the network device determines that the carrier measurement results corresponding to different carriers in the inter-band carrier aggregation can be reused, the network device can not perform carrier measurement configuration on some carriers in the inter-band carrier aggregation, and the terminal also does not need to perform carrier measurement on some carriers, thereby greatly saving power consumption of the terminal and the network device. On the other hand, in the above embodiment, the carrier measurement results corresponding to different inter-band carriers will be reused only when the terminal meets the condition that the carrier measurement results between different inter-band carriers can be reused. At this time, when the carrier measurement results corresponding to different inter-band carriers are reused, the accuracy of the carrier measurement will not be affected. Therefore, it can be seen that the embodiment of the present disclosure can not only save power consumption of the terminal and the network device, but also ensure the accuracy of carrier measurement.

[0069] In conjunction with some embodiments of the second aspect, in some embodiments, the first condition includes at least one of the following:

[0167] Optionally, in a communication system, carrier aggregation (CA) technology is introduced to increase uplink and downlink transmission rates. Optionally, CA may include inter-band carrier aggregation (ICA), where different carriers used for aggregation in ICA belong to different frequency bands. Optionally, network equipment typically configures a terminal to perform carrier measurement on multiple inter-band carriers in ICA. Current methods for measuring carriers of multiple inter-band carriers consume high power.

[0168] FIG2A1 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A1 , the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The method includes:

[0169] Step 2101: The network device sends a second configuration to a terminal, where the second configuration is used to configure the terminal to perform carrier measurement on a first carrier.

[0170] Optionally, the terminal may receive the second configuration.

[0171] Optionally, the second configuration may be used to configure the terminal to perform carrier measurement on a first carrier in inter-band carrier aggregation. Optionally, in inter-band carrier aggregation, different carriers used for carrier aggregation belong to different frequency bands. The first carrier may be any carrier in inter-band carrier aggregation. For example, the first carrier may be a carrier corresponding to a primary cell or a primary / secondary cell, or the first carrier may be a carrier corresponding to a secondary cell.

[0172] Optionally, the second configuration may include, for example, at least one of the following:

[0173] An object to be measured on the first carrier, where the object to be measured may be, for example, a reference signal, such as a synchronization signal block (SSB) and / or a channel-state information reference signal (CSI-RS);

[0174] The carrier measurement content, for example, may include at least one of layer 1 reference signal received power (L1-RSRP) measurement and L3-RSRP measurement.

[0175] Optionally, the above content is only an example description, and the second configuration may also include other content, which is not limited in this disclosure.

[0176] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0177] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0178] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0179] Step 2102: The terminal performs carrier measurement on the first carrier based on the second configuration.

[0180] 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.

[0181] Step 2103: The terminal reports the carrier measurement result corresponding to the first carrier to the network device.

[0182] Step 2104: The network device determines whether to reuse the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier according to whether the terminal meets the first condition.

[0183] Optionally, the second carrier is a carrier for which carrier measurement configuration is not performed in inter-band carrier aggregation. For example, the second carrier may be a carrier corresponding to a secondary cell.

[0184] Optionally, the first condition may be used to indicate a condition that must be met when carrier measurement results between different inter-band carriers can be reused. Optionally, "different inter-band carriers" herein may be understood as, for example, different carriers in inter-band carrier aggregation.

[0185] Optionally, the first condition may include at least one of the following:

[0186] A difference between the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier is less than a first threshold;

[0187] The terminal is in a first state, and in the first state, the moving speed of the terminal is less than a second threshold. Optionally, the first state can be understood as, for example, a low mobility status.

[0188] Optionally, in some embodiments, when the network device determines that the terminal meets the first condition, it determines that the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation can be reused for the second carrier.

[0189] Optionally, in some embodiments, when the network device determines that the terminal does not meet the first condition, it determines that the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation cannot be reused for the second carrier.

[0190] Optionally, the following takes the “carrier measurement result of L1-RSRP” as an example to introduce the principle of “why when the gap between different inter-band carriers is less than the first threshold, and / or when the terminal is in the first state, it is considered that the carrier measurement results between different inter-band carriers can be reused with each other”.

[0191] Alternatively, L1-RSRP can provide instantaneous channel quality. In a fast-fading channel model, Doppler shift affects the channel model and the corresponding received signal power level (L1-RSRP). Alternatively, Doppler shift depends on the carrier frequency and terminal speed. Therefore, if a network device attempts to reuse the L1-RSRP measurement of one carrier for another carrier, two factors need to be considered:

[0192] 1. The frequency difference between the two carriers;

[0193] 2. Terminal velocity.

[0194] Optionally, for inter-band carrier aggregation under FR1, there are several band combinations. For some band combinations, the frequencies between different inter-band carriers are close to each other, such as 800 MHz (megahertz) and 900 MHz. For some other band combinations, the frequencies between different inter-band carriers are far apart, such as 800 MHz and 1.5 / 2.5 / 3.5 GHz (gigahertz). In addition, the terminal may have different speeds, such as 5 km / h (kilometers per hour) or 30 km / h. The frequency difference and different speeds between the two carriers will affect the carrier measurement results of L1-RSRP on the two carriers. The following provides simulation results for different band combinations. Assume that there are 4 inter-band carriers with center frequencies of 800 MHz, 900 MHz, 1.5 GHz, and 2.5 GHz, respectively. If the terminal speed is 5 km / h, Figure 2A2 shows the L1-RSRP gap between two carriers of different frequencies in a low mobility state according to an embodiment of the present disclosure. As shown in Figure 2A2, as the frequency gap between the two carriers increases, the gap between the L1-RSRPs also increases. For example, for 800MHz and 900MHz, the L1-RSRP gap is very small, less than 1dB in 90% of cases. Therefore, it is reasonable to use the L1-RSRP of the 800MHz carrier to replace the 900MHz carrier. However, if the frequency band combination is 800MHz and 1.5G / 2.5GHz, the gap between the L1-RSRPs increases to 2-3dB, making it inappropriate to reuse the L1-RSRP of the 800MHz carrier for the 1.5G / 2.5GHz carrier.

[0195] Optionally, FIG2A3 is a 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, when the terminal moves faster, the Doppler spread increases. In FIG2A3, when the terminal is in a low mobility state (i.e., 5km / h), the RSRP gap between 800MHz and 900MHz is small. 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 only when the terminal is in a low mobility state can the RSRP between different carriers be reused.

[0196] Optionally, Figure 2A4 shows the L1-RSRP gap between the two carriers of 800MHz and 1.5GHz when the terminal moving speed is 5km / h and 30km / h according to an embodiment of the present disclosure. As shown in Figure 2A4, due to the large terminal moving speed, the L1-RSRP gap between the two carriers of 800MHz and 1.5GHz will be further expanded.

[0197] It can be seen that when the carrier frequency difference between different carriers is small, and / or when the terminal's mobile speed is low, the difference in carrier measurement results between different carriers is small and can be reused. Therefore, in one embodiment of the present disclosure, the first condition mentioned above can include at least one of the following:

[0198] A difference between the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier is less than a first threshold;

[0199] The terminal is in a first state.

[0200] Optionally, in some embodiments, the network device needs to first determine whether the terminal meets the first condition. When the network device determines that the terminal meets the first condition, it determines 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 meet the first condition, it determines not to reuse the carrier measurement result corresponding to the first carrier in the inter-band carrier aggregation for the second carrier.

[0201] Optionally, since the carrier-related parameters of the terminal are configured by the network device, the network device can directly know the carrier frequency corresponding to the first carrier and the carrier frequency corresponding to the second carrier, and the network device can 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.

[0202] Optionally, when the first condition includes: the terminal is in the first state, the method for the network device to determine whether the terminal is in the first state may include at least one of the following:

[0203] The first method is: the terminal reports a first signaling to the network device, where the first signaling may be used to indicate a moving speed of the terminal. The network device may determine whether the terminal is in the first state based on the moving speed of the terminal indicated by the first signaling.

[0204] Optionally, the terminal can autonomously measure its moving speed and periodically or aperiodically report the first signaling to the network device based on the measured moving speed. Optionally, the first signaling can be an existing signaling or a newly designed signaling, which is not limited in this disclosure.

[0205] The second type: 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.

[0206] Optionally, the uplink signal may be, for example, an SRS and / or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). Optionally, the uplink signal may be sent by the terminal via the first carrier.

[0207] Optionally, in some embodiments, terms such as "uplink", "uplink", "physical uplink" can be replaced with each other, and terms such as "downlink", "downlink", "physical downlink" can be replaced with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be replaced with each other.

[0208] The third type: The network device receives the carrier measurement results corresponding to the first carrier reported by the terminal at at least two different times. When the difference between the carrier measurement results corresponding to the first carrier at different times is less than a third threshold, the terminal is determined to be in the first state; when the difference between the carrier measurement results corresponding to the first carrier at different times is greater than or equal to the third threshold, the terminal is determined not to be in the first state. Alternatively, when the difference between the carrier measurement results corresponding to the first carrier at different times is less than or equal to the third threshold, the terminal is determined to be in the first state; when the difference between the carrier measurement results corresponding to the first carrier at different times is greater than the third threshold, the terminal is determined not to be in the first state.

[0209] Step 2105: The network device determines that the terminal meets the first condition, and reuses the carrier measurement result corresponding to the first carrier for the second carrier.

[0210] Optionally, when the network device determines that the terminal meets the first condition, it means that the carrier measurement results between different inter-band carriers can be reused with each other. 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. As a result, the terminal does not need to perform carrier measurement and reporting on the second carrier, which can save signaling interaction between the terminal and the network device, reduce communication overhead, save power consumption and power of the terminal and the network device, and achieve the purpose of saving power.

[0211] Optionally, the execution order of steps 2104-2105 and steps 2101-2103 may be swapped, for example, steps 2104-2105 may be executed first, and then steps 2101-2103; or, steps 2104-2105 and steps 2101-2103 may be executed simultaneously, or, steps 2104-2105 may be executed alternately with steps 2101-2103, for example, step 2101 may be executed first, then steps 2104-2105, and then steps 2102 and 2103; or, step 2104 may be executed first, then steps 2101-2103, and then step 2105. This disclosure is not limited to this.

[0212] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2105. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and steps 2101+2102 may be implemented as independent embodiments, but are not limited thereto.

[0213] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

For example, step 5101 may be implemented as an independent embodiment, and step 5104 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0319] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0320] The following is an exemplary introduction to the above method.

[0321] L1-RSRP

[0322] In the current inter-band FR1 inter-band CA, the NW (i.e., the aforementioned network device) will configure and send 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.

[0323] Optionally, L1-RSRP provides real-time channel quality. In a fast fading channel model, Doppler shift affects the channel model and the corresponding received signal power level (L1-RSRP). Taking the tapped delay line (TDL) model as an example, in a fast fading model, the Doppler shift is as follows:

[0324] The Doppler frequency component depends on the angle of arrival (AOA, ZOA), and the UT velocity vector v with velocity v, azimuth of travel φv, and elevation angle θv, and is given by

[0325] Doppler shift depends on the carrier frequency and UE speed. The angle of arrival of the ray also affects Doppler. However, since all carriers are located in the same area, the angle of arrival of the ray is the same. Therefore, we do not need to consider the effect of angle of arrival differences.

[0326] Therefore, if the base station attempts to reuse L1-RSRP measurements of one carrier for another carrier for co-located inter-band FR1CA, two factors need to be considered:

[0327] 1. The frequency difference between the two carriers

[0328] UE speed and angle

[0329] For inter-band FR1CA, there are several band combinations. For some band combinations, the two carriers of SCells are close to each other, such as 800MHz and 900MHz. For some other band combinations, the two carriers are farther apart, such as 800MHz and 1.5 / 2.5 / 3.5GHz. In addition, the UE may have different speeds, such as 5km / h or 30km / h.

[0330] The frequency gap between the two carriers and the different speeds will affect the signal levels on the two carriers.

[0331] Optionally, simulation results for different band combinations are provided. Assume there are four carriers with center frequencies of 800 MHz, 900 MHz, 1.5 GHz, and 2.5 GHz.

[0332] Optionally, the UE speed for all carriers is 5 km / h. We compared the L1-RSRP between different operators in a low mobility state, as shown in Figure 2A2 above. Optionally, as the frequency gap between two carriers increases, the RSRP gap also increases. Taking 800 MHz and 900 MHz as an example, the RSRP gap is very small, for example, less than 1 dB in 90% of cases. Therefore, it is reasonable to use the L1-RSRP of the 800 MHz carrier instead of the 900 MHz carrier. However, if the frequency band combination is 800 MHz and 1.5 GHz / 2.5 GHz, the RSRP gap increases to 2-3 dB. Therefore, it is inappropriate to reuse the result for another SCell. Therefore, it is necessary to define a frequency gap between the two carriers to facilitate reuse.

[0333] Optionally, the L1-RSRP gap at different speeds is also simulated. In FIG2A3 above, the RSRP gap between 5 km / h and 30 km / h at 800 MHz and 900 MHz is compared.

[0334] Alternatively, when the UE moves faster, the Doppler spread increases. Then, the RSRP gap between 800MHz and 900MHz will increase. In Figure 1, when in a low mobility state, the RSRP gap between 800MHz and 900MHz is small. However, as shown in Figure 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 a low mobility state. We also simulated the RSRP gap between 800MHz and 1.5GHz when V = 5km / h and 30km / h, as shown in Figure 2A4 above.

[0335] This also suggests that the RSRP gap between the two carriers will widen further due to the greater speeds.

[0336] In summary, if the NW attempts to reuse the L1-RSRP of one cell to another Scell ​​in inter-band FR1 CA, the applicability should consider two conditions:

[0337] 1. The frequency gap is less than [x] Hz.

[0338] 2. UE is in low mobility state

[0339] These two conditions can be used individually or in combination.

[0340] For low mobility states, there are several options for obtaining information:

[0341] Option 1: The UE sends speed-related information to the NW. Signaling for UE speed indication needs to be designed.

[0342] Option 2: The NW calculates the UE's mobility status based on a certain UL signal.

[0343] Option 3: The UE sends two L1-RSRP reports to the NW in different time slots. If the RSRP difference between the two L1-RSRP reports is small, the NW will consider the UE to be in a low mobility state.

[0344] As for the frequency gap information, the NW will know it when configuring CA.

[0345] The power saving procedure is as follows:

[0346] If the frequency gap between two carriers in CA is less than [X] Hz,

[0347] - If the UE is in a low mobility state, the NW will not configure L1-RSRP measurements for a cell. The NW will reuse the L1-RSRP report of one carrier for another carrier. This will save power for both the NW and the UE.

[0348] - If the UE is not in low mobility state, the NW shall configure L1-RSRP measurements for both cells.

[0349] Otherwise, if the frequency interval between the two carriers in CA is greater than [X] Hz,

[0350] -NW will configure L1-RSRP measurement for both cells

[0351] L3-RSRP

[0352] For L3-RSRP measurements, the UE will perform time-domain filtering based on the L1-RSRP measurements. Due to averaging, the Doppler effect can be reduced. Therefore, for L3-RSRP measurements, there may only be a frequency gap threshold.

[0353] The power saving procedure is as follows:

[0354] If the frequency gap between two carriers in CA is less than [X] Hz,

[0355] - The NW does not configure L3-RSRP measurement for a cell. The NW reuses the L3-RSRP report of one carrier for another carrier. This saves power for both the NW and the UE.

[0356] Otherwise, if the frequency interval between the two carriers in CA is greater than [X] Hz,

[0357] - The NW will configure L3-RSRP measurements for both cells.

[0358] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
