For a better understanding of the solution provided by the present application, the following description will be given with reference to the accompanying drawings in the embodiments of the present application.

The communication system related to the present application is shown in fig. 1, and the communication system may include, but is not limited to, one terminal device and one network device, and the number and form of the devices shown in fig. 1 are used for example and do not constitute a limitation to the embodiments of the present application, and in practical applications, more than one network device may be included. The communication system shown in fig. 1 is illustrated by taking a terminal device 101, a network device 1021, a network device 1022, and a network device 1023 as an example, where a cell corresponding to the network device 1021 is a current serving cell of the terminal device 101, and a cell corresponding to the network device 1022 and a cell corresponding to the network device 1023 are two neighboring cells detected by the terminal device 101. It should be understood that the number of cells corresponding to the network device in fig. 1 is only exemplary, and is not limited thereto.

In this application, a terminal device can also be called a terminal, user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, user agent, or user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

Currently, in a Long Term Evolution (LTE) system, a signal can be divided into 10 different types of subframes (1ms) per radio frame (10 ms): subframe 0, subframe 1, subframe 2, subframe 3, subframe 4, subframe 5, subframe 6, subframe 7, subframe 8, and subframe 9, where subframe 0 and subframe 5 would typically be configured with a cell RS. Therefore, the terminal device usually selects subframe 0 or subframe 5 as a valid measurement subframe, and measures the RS configured in the valid measurement subframe. However, if the terminal device receives the effective measurement subframe by using a certain fixed receiving method, the receiving method may not be the optimal receiving method in the current communication scenario, and thus the performance of the terminal device may be degraded.

In order to solve the above problems, the present application provides a method for receiving an effective measurement subframe, where a terminal device may flexibly select a receiving manner of the effective measurement subframe according to a synchronization deviation between any two cells of a plurality of cells detected in a current communication scenario and an effective measurement subframe of each neighboring cell, so that the terminal device may receive the effective measurement subframe according to a receiving manner adapted to the current communication scenario, thereby improving performance of the terminal device.

The technical scheme provided by the application can be applied to various communication systems, such as a global system for mobile communication, an LTE frequency division duplex system, an LTE time division duplex system, a universal mobile communication system, a new wireless system, a communication system of subsequent evolution and the like.

To facilitate an understanding of the embodiments disclosed herein, some concepts related to the embodiments of the present application will be first explained. The description of these concepts includes, but is not limited to, the following.

And (3) frame structure: as shown in fig. 2, a frame structure of the LTE system of 3GPP is that one radio frame is 10ms long in the time domain, and each radio frame is divided into 10 subframes with time domain length of 1 ms.

Reference signal: in a communication system, a reference signal may be used to estimate a channel, coherently demodulate a received signal containing control or data information, and measure a channel state/channel quality, so that scheduling, or selection of a cell, a transmission point, or a reception point, etc. may be implemented. In The3rd Generation Partnership Project (3 GPP) Long Term Evolution Project (LTE) downlink system, reference signals for coherent demodulation are referred to as demodulation reference signals (DMRSs), which are also referred to as User Equipment (UE) -specific reference signals (UE-specific reference signals) and reference signals for channel state information measurement are referred to as channel state information reference signals (CSI-RS). DMRS is transmitted together in a Physical Downlink Shared Channel (PDSCH) and used for channel estimation during demodulation of the PDSCH. The CSI-RS may be used for the UE of the R10 system to measure the channel state, especially for the case of multi-antenna transmission. A Rank Indicator (RI)/Precoding Matrix Indicator (PMI)/Channel Quality Indicator (CQI), and other feedback information may be derived based on channel measurement of the CSI-RS. In addition, a cell specific reference signal (CRS) may be used for UE channel estimation, so as to implement demodulation of a Physical Downlink Control Channel (PDCCH) and other common channels, and the reference signal is inherited from the LTE R8/9 system. CRS is also used in LTE R8/9 systems for measurement of channel state information and demodulation of data channels. In LTE R8-R11 systems, it is also used for measurement of signal quality information to facilitate selection of cells or transmission or reception points.

Valid measurement subframes: for 10 subframes corresponding to one radio frame, the terminal device needs to measure the RS configured in the subframe. In other words, some of the 10 subframes included in one radio frame may be configured with cell RS, and the terminal device may determine one or more valid measurement subframes from the subframes configured with cell RS. For example, a radio frame includes 10 subframes: subframe 0, subframe 1, subframe 2, subframe 3, subframe 4, subframe 5, subframe 6, subframe 7, subframe 8 and subframe 9, and assuming that subframe 0, subframe 2, subframe 5 and subframe 6 are all configured with a cell RS and a terminal device selects to measure the RS configured in subframe 0 and subframe 5, subframe 0 and subframe 5 are referred to as valid measurement subframes at this time.

Signal to Interference Noise Ratio (SINR): is the ratio of the signal to the sum of interference and noise in the system. A signal is an electronic signal from outside the device that needs to be processed by the device. The interference refers to interference caused by the system itself and different systems, such as frequency interference and multipath interference. Noise refers to an irregular extra signal that does not exist in the original signal generated after passing through the device, and such a signal is environment-dependent and does not change with the change of the original signal.

The following further describes a method for receiving an effective measurement subframe provided in the embodiment of the present application:

referring to fig. 3, fig. 3 is a schematic flow chart of a method for effectively measuring subframes according to an embodiment of the present disclosure. As shown in fig. 3, the method for receiving a valid measurement subframe includes steps S301 to S303.

S301: determining first information, wherein the first information comprises synchronization deviation between any two cells in a plurality of cells or the first information comprises a valid measurement subframe set of at least one neighbor cell, the plurality of cells comprise a plurality of neighbor cells, or the plurality of cells comprise a serving cell and a neighbor cell, the valid measurement subframe set comprises one or more valid measurement subframes, and the valid measurement subframes are subframes containing cell reference signals.

The terminal equipment detects the synchronization deviation between any two cells in the plurality of cells, wherein the synchronization deviation refers to the deviation between the wireless frames of the two cells. The terminal device determines an effective measurement subframe set of each neighboring cell, where the effective measurement subframe set includes an effective measurement subframe of the neighboring cell and a target number of the effective measurement subframes of the neighboring cell (or referred to as a target number of the effective measurement subframes of the neighboring cell that need to be received).

In one possible implementation, the terminal device may determine, according to a preset valid measurement subframe calculation rule and configuration information of each neighboring cell, each valid measurement subframe in a valid measurement subframe set of at least one neighboring cell, that is, determine which of signal subframes of each neighboring cell are valid measurement subframes. The preset effective measurement subframe calculation rule is set by a developer according to an experimental measurement and calculation scene, and can be correspondingly adjusted according to a specific application scene without excessive limitation. The configuration Information refers to Information related to protocol configuration signaling, such as mode of neighbor measurement subframes, signal bandwidth configuration, System master Information Block 2(System Information Block Type2, SIB2), System master Information Block 1(System Information Block Type1, SIB1), System master Information Block 3(System Information Block Type3, SIB3), System master Information Block 5(System Information Block Type5, SIB5), Multicast Single Frequency Network (MBSFN) subframe configuration, uplink subframe and downlink subframe configuration Information, and the like.

In a possible implementation, the terminal device may further obtain a bandwidth corresponding to the at least one neighboring cell or measure an SINR of the at least one neighboring cell, and determine, according to the SINR or the bandwidth, a target number of effective measurement subframes of an effective measurement subframe set of each neighboring cell in the effective measurement subframe set of the at least one neighboring cell. It should be understood that the target number of the valid measurement subframes of the neighboring cell is related to the preset measurement accuracy and the signal quality, if the preset measurement accuracy is a fixed value, the worse the signal quality is, the more the target number of the valid measurement subframes of the neighboring cell needs to be received, and if the signal quality is regarded as unchanged, the higher the preset measurement accuracy is, the more the target number of the valid measurement subframes of the neighboring cell needs to be received. The preset measurement precision is obtained by measurement and calculation of developers according to the experimental application scene, and corresponding adjustment can be carried out subsequently according to the specific application scene without excessive limitation.

In one possible implementation, before the terminal device determines the first information, the terminal device obtains whether the working carrier frequency of the serving cell is the same as the carrier frequencies of the neighboring cells. And if the working carrier frequency of the service cell is the same as the carrier frequency of the adjacent cell, the plurality of cells comprise the service cell and the adjacent cell. It should be noted that the carrier frequencies of the neighboring cells detected by the terminal device are all the same.

In other words, when the terminal device detects that the working carrier frequency of the serving cell is the same as the carrier frequency of the neighboring cell, the synchronization deviation between any two cells in the multiple cells included in the first information is the synchronization deviation between any two cells in the serving cell and the neighboring cell. For example, when the terminal device detects that the working carrier frequency of the serving cell, the carrier frequency of the neighboring cell 1, and the carrier frequency of the neighboring cell 2 are the same, the first information may include a synchronization deviation between the serving cell and the neighboring cell 1, a synchronization deviation between the serving cell and the neighboring cell 2, and a synchronization deviation between the neighboring cell 1 and the neighboring cell 2.

In a possible implementation, if the working carrier frequency of the serving cell is different from the carrier frequency of the neighboring cell, the plurality of cells include a plurality of neighboring cells. In other words, when the terminal device detects that the working carrier frequency of the serving cell is different from the carrier frequency of the neighboring cell, the synchronization deviation between any two cells in the multiple cells included in the first information is the synchronization deviation between any two neighboring cells in the multiple neighboring cells. For example, when the terminal device detects that the working carrier frequency of the serving cell, the carrier frequency of the neighboring cell 1, and the carrier frequency of the neighboring cell 2 are the same, the first information may include a synchronization deviation between the neighboring cell 1 and the neighboring cell 2.

S302: and determining a target receiving mode from a plurality of preset effective measuring subframe receiving modes according to the first information.

The terminal device may determine the target receiving mode from a plurality of preset valid measuring subframe receiving modes according to a synchronization deviation between any two cells of the plurality of cells or a valid measuring subframe set of at least one neighboring cell. The receiving mode of the preset effective measuring subframes is set by developers according to the experimental environment and can be correspondingly adjusted according to a specific application scene.

In one possible implementation, the plurality of preset valid measurement subframe receiving manners include a first receiving manner, and if synchronization deviations between any cells in the plurality of cells are smaller than a first threshold, or if a valid measurement subframe set of at least one neighboring cell includes all downlink subframes of the at least one neighboring cell, it is determined that the first receiving manner is a target receiving manner. The first threshold is obtained by measurement and calculation of developers according to experimental data, and can be adjusted and set correspondingly according to specific application scenes without excessive limitation.

Exemplarily, the terminal device detects a serving cell, a neighboring cell 1, and a neighboring cell 2, and if a working carrier frequency of the serving cell is different from a carrier frequency of the neighboring cell, the first information includes a synchronization deviation between the neighboring cell 1 and the neighboring cell 2. In this case, if the first threshold is 0.2ms and the synchronization deviation between the neighboring cell 1 and the neighboring cell 2 is 0.1ms, the terminal device may determine that the first receiving method is the target receiving method.

In another example, if the terminal device determines that all downlink subframes of the neighboring cell are valid measurement subframes according to the neighboring cell configuration information and a preset cell valid measurement subframe calculation rule, the terminal device may determine that the first receiving mode is a target receiving mode.

In one possible implementation, the plurality of preset valid measurement subframe receiving manners further include a second receiving manner, and if synchronization deviations between any cells in the plurality of cells are not smaller than the first threshold, and if the valid measurement subframe set of at least one neighboring cell does not include all downlink subframes of the at least one neighboring cell, it is determined that the second receiving manner is the target receiving manner.

Illustratively, the terminal device detects a serving cell, a neighboring cell 1, and a neighboring cell 2, and a working carrier frequency of the serving cell is the same as a carrier frequency of the neighboring cell, so that the first information includes a synchronization deviation between the serving cell and the neighboring cell 1 of 0.1ms, a synchronization deviation between the serving cell and the neighboring cell 2 of 0.3ms, and a synchronization deviation between the neighboring cell 1 and the neighboring cell 2 of 0.2 ms. In this case, if the first threshold is 0.2ms, since the synchronization deviation 0.3ms between the serving cell and the neighboring cell 2 is greater than the first threshold 0.2ms, and if the terminal device determines that all downlink subframes of the neighboring cell are not all valid measurement subframes according to the neighboring cell configuration information and the preset cell valid measurement subframe calculation rule, that is, some downlink subframes are valid measurement subframes and some downlink subframes are invalid measurement subframes. In such a case, the terminal device may determine that the second reception scheme is the target reception scheme.

It should be noted that, in one possible implementation, if all downlink subframes of the neighboring cells are not all valid measurement subframes, but valid measurement subframes in valid measurement subframe sets of the neighboring cells in the multiple cells are all the same, the terminal device determines that the first receiving method is the target receiving method. In other words, if the valid measurement subframes included in the valid measurement subframe sets of the respective neighboring cells detected by the terminal device are all the same, the terminal device determines that the first receiving mode is the target receiving mode.

Illustratively, the neighboring cells detected by the terminal device are neighboring cell 1, neighboring cell 2, and neighboring cell 3. In this case, if the valid measurement subframes included in the valid measurement subframe set of the neighboring cell 1 are subframe 0 and subframe 5, the valid measurement subframes included in the valid measurement subframe set of the neighboring cell 2 are subframe 0 and subframe 5, and the valid measurement subframes included in the valid measurement subframe set of the neighboring cell 3 are subframe 0 and subframe 5, the terminal device determines that the first receiving mode is the target receiving mode.

S303: and receiving the effective measurement subframe of at least one adjacent cell in a target receiving mode.

The terminal device can start the radio frequency to receive the effective measurement subframe of at least one adjacent region according to the radio frequency starting time and the radio frequency duration of each time of the terminal device set in the target receiving mode. The receiving of the valid measurement subframe of at least one neighboring cell may refer to receiving valid measurement subframes of all neighboring cells detected by the terminal device, or may refer to receiving valid measurement subframes of one or some neighboring cells in the neighboring cells detected by the terminal device.

In one possible implementation, the terminal device receives, in a first receiving manner, the valid measurement subframe of at least one neighboring cell as follows: and further, receiving the effective measurement subframe of at least one adjacent cell based on the radio frequency turn-on time and the radio frequency duration of the terminal device each time. In other words, the target neighbor cell is a neighbor cell with the best signal quality or a neighbor cell with the strongest signal strength among all neighbor cells, and the terminal device determines the radio frequency turn-on time and the radio frequency duration of each time to receive the effective measurement subframe of at least one neighbor cell by taking the target neighbor cell as a reference. By implementing the possible implementation mode, the terminal equipment determines the radio frequency starting time and the radio frequency duration according to the target adjacent cell with the optimal signal quality in the plurality of adjacent cells, and reduces the radio frequency starting frequency of the terminal equipment, thereby reducing the power consumption of the terminal equipment.

Illustratively, the first threshold is 0.2ms, the terminal device detects that the working carrier frequency of the serving cell is the same as the carrier frequencies of the neighboring cells (neighboring cell 1 and neighboring cell 2), and the effective measurement subframes of the neighboring cell 1 and the neighboring cell 2 are both subframe 0 and subframe 5. Further, the terminal device includes, according to the synchronization deviation 0.1ms between the serving cell and the neighboring cell 1, the synchronization deviation 0.15ms between the serving cell and the neighboring cell 2, and the synchronization deviation 0.05ms between the neighboring cell 1 and the neighboring cell 2, which are included in the first information, and a time mapping relationship among the serving cell timing, the neighboring cell 1 timing, and the neighboring cell 2 timing is as shown in fig. 4. In this case, the terminal device may determine that the first receiving mode is the target receiving mode, and the terminal device may detect the signal quality parameters of the neighboring cell 1 and the neighboring cell 2, compare the signal quality parameters of the neighboring cell 1 and the neighboring cell 2, and know that the signal quality parameter of the neighboring cell 2 is greater than the signal quality parameter of the neighboring cell 1, the terminal device may determine the neighboring cell 2 as the target neighboring cell, and set the radio frequency on-time and the radio frequency duration of the terminal device for each time based on the valid measurement subframe of the neighboring cell 2. In other words, the terminal device starts the radio frequency at the valid measurement subframes (subframe 0 and subframe 5) of the neighboring cell 2, and the duration of the radio frequency is the length of the valid measurement subframes (subframe 0 and subframe 5) of the neighboring cell 2, that is, the duration of the radio frequency is 1 ms.

In a possible implementation, the terminal device receives, in the second receiving manner, the valid measurement subframe of the at least one neighboring cell as follows: and further, receiving the effective measurement subframe of the at least one adjacent cell based on the radio frequency starting time and the radio frequency duration of the terminal equipment each time. By means of the possible implementation mode, the terminal device determines the radio frequency starting time and the radio frequency duration according to the effective measurement subframe set of each adjacent cell, effective measurement subframes of all adjacent cells are considered, and the accuracy of the terminal device in measuring the RS in the effective measurement subframes is improved.

Illustratively, the first threshold is 0.2ms, the terminal device detects that the working carrier frequency of the serving cell is different from the carrier frequencies of the neighboring cells (neighboring cell 1 and neighboring cell 2), and the effective measurement subframes of the neighboring cell 1 and the neighboring cell 2 are both subframe 0 and subframe 5. Further, the terminal device, according to the synchronization deviation 1.7ms between the serving cell and the neighboring cell 1, the synchronization deviation 3.7ms between the serving cell and the neighboring cell 2, and the synchronization deviation 2ms between the neighboring cell 1 and the neighboring cell 2 included in the first information, and a time mapping relationship among the serving cell timing, the neighboring cell 1 timing, and the neighboring cell 2 timing is as shown in fig. 5. In this case, the terminal device may determine that the second receiving method is the target receiving method, and set the radio frequency on-time and the radio frequency duration of the terminal device each time according to the time mapping relationship among the serving cell timing, the neighboring cell 1 timing, and the neighboring cell 2 timing, and all valid measurement subframes in the valid measurement subframe sets of the neighboring

cells

1 and 2. In other words, the terminal device starts a radio frequency at a serving cell subframe corresponding to the valid measurement subframe (subframe 0 and subframe 5) of the neighboring cell 1 and the valid measurement subframe (subframe 0 and subframe 5) of the neighboring cell 2, and the radio frequency duration is one subframe length of the serving cell, that is, the radio frequency duration is 1 ms.

It should be noted that, taking the effective measurement subframe 0 of the neighboring cell 1 in fig. 5 as an example, the effective measurement subframe 0 is mapped to the corresponding serving cell subframe 1 and subframe 2, the number of symbols of the effective measurement subframe 0 of the neighboring cell 1 mapped to the serving cell subframe 1 and the number of symbols of the serving cell subframe 2 can be calculated according to the mapping relationship, and since the number of symbols of the effective measurement subframe 0 of the neighboring cell 1 mapped to the serving cell subframe 1 is less than two, it is determined that the subframe 2 of the serving cell radio frequency starts to receive the effective measurement subframe (subframe 0) of the neighboring cell 1. In other words, when it is determined that the second reception method is the target reception method, for any valid measurement subframe of each neighboring cell, the terminal device sets the radio frequency on time based on the subframe of the serving cell by the number of symbols mapped between the valid measurement subframe and the subframe of the serving cell.

Therefore, by the method for receiving the effective measurement subframe, the terminal equipment can flexibly determine a target receiving mode according to the configuration information of the adjacent cell in the current communication scene and the synchronization deviation between any two cells, so that the receiving mode of the effective measurement subframe is adaptive to the current communication scene, and the performance of the terminal equipment is improved.

Referring to fig. 6, fig. 6 is a schematic flow chart of another method for effectively measuring subframes according to an embodiment of the present disclosure. As shown in fig. 6, the method for receiving valid measurement subframes includes steps S601 to S605.

S601: determining first information, wherein the first information comprises synchronization deviation between any two cells in a plurality of cells or the first information comprises a valid measurement subframe set of at least one neighbor cell, the plurality of cells comprise a plurality of neighbor cells, or the plurality of cells comprise a serving cell and a neighbor cell, the valid measurement subframe set comprises one or more valid measurement subframes, and the valid measurement subframes are subframes containing cell reference signals.

S602: and determining a target receiving mode from a plurality of preset effective measuring subframe receiving modes according to the first information.

The specific implementation manners of steps S601 to S602 may refer to the specific implementation manners of steps S301 to S302 in the foregoing embodiments, and are not described in detail here.

S603: and determining the total duration and the total radio frequency starting duration according to the radio frequency duration and the first information of the terminal equipment corresponding to the target receiving mode each time.

After the terminal device determines a target receiving mode (which may also be referred to as a first target receiving mode), according to the radio frequency start and the radio frequency duration of each time of the terminal device corresponding to the target receiving mode, and the first information, determining the total duration of the terminal device receiving the at least one neighbor cell valid measurement subframe set and the total radio frequency start duration of the terminal device. The total duration is the duration from the first radio frequency starting time of the terminal equipment to the effective measurement subframe end time of the terminal equipment for receiving at least one adjacent cell; the total radio frequency starting time is the sum of the radio frequency duration of each time of the terminal equipment.

In one possible implementation, the terminal device determines the total duration and the total duration of the radio frequency activation according to the valid measurement subframe set (including the valid measurement subframes and the target number of the valid measurement subframes) of the at least one neighboring cell and the radio frequency duration of the terminal device corresponding to the target receiving mode each time in the first information.

Exemplarily, as shown in fig. 7, the positions of the valid measurement subframes of the neighboring cell 1 are subframe 0 and subframe 5, the target number in the valid measurement subframe set of the neighboring cell 1 is 2, the positions of the valid measurement subframes of the neighboring cell 2 are subframe 0 and subframe 5, and the target number in the valid measurement subframe set of the neighboring cell 2 is 2. If the radio frequency duration corresponding to each radio frequency turn-on of the terminal device is 1ms (i.e., the radio frequency duration of each radio frequency turn-on in fig. 7 is 1ms), the total radio frequency turn-on duration of the terminal device is 4ms, and the total radio frequency duration is 8 ms.

S604: and if the ratio of the total duration to the total radio frequency starting duration is greater than or equal to a second threshold, updating the target receiving mode to a third receiving mode.

And the terminal equipment calculates the ratio of the total duration to the total radio frequency starting duration according to the total duration and the radio frequency starting duration obtained in the step S603. If the ratio is greater than or equal to the second threshold, the target receiving manner (the target receiving manner is the first target receiving manner adopted by the total duration and the total rf on duration calculated in step S603) is updated to the third receiving manner, that is, the terminal device determines the third receiving manner as the target receiving manner (which may be different from the first target receiving manner and is referred to as the second target receiving manner). The second threshold is a rational number greater than 1, and can be set by a developer according to the experimental scene measurement and calculation, and can be adjusted correspondingly according to the specific application scene subsequently without limitation.

S605: and receiving the effective measurement subframe of at least one adjacent cell by a third receiving mode.

And the terminal equipment determines the radio frequency starting time and the radio frequency duration of each time according to the effective measurement subframe set of at least one adjacent cell and the time mapping relation between the at least one adjacent cell and the service cell, wherein the radio frequency duration covers each effective measurement subframe in the at least one adjacent cell. By the receiving mode, as the ratio of the total duration of the terminal equipment to the total radio frequency starting duration is close to a certain expected value, the smaller the expected value is, the closer the total duration and the total radio frequency starting duration are, and at the moment, the power consumption of the terminal equipment increased by the receiving mode is far less than the power consumption saved by saving the software calculation complexity of the terminal equipment.

Illustratively, the terminal device receives the valid measurement subframes according to the third receiving manner, as shown in fig. 8, the terminal device detects the working carrier frequency of the serving cell and the neighboring cells (neighboring cell 1 and neighboring cell 2), and the valid measurement subframes of the neighboring cell 1 and the neighboring cell 2 are both subframe 0 and subframe 5. The terminal device may set a radio frequency on-time and a radio frequency duration of each time of the terminal device according to a time mapping relationship among the serving cell timing, the neighboring cell 1 timing and the neighboring cell 2 timing, and all valid measurement subframes in the valid measurement subframe sets of the neighboring

cells

1 and 2, where the radio frequency duration covers each valid measurement subframe in at least one neighboring cell. In other words, the terminal device starts the radio frequency at the serving cell subframe corresponding to the effective measurement subframe (subframe 0 and subframe 5) of the neighboring cell 1 and the effective measurement subframe (subframe 0 and subframe 5) of the neighboring cell 2, and the radio frequency duration is the length of the subframe covering each effective measurement subframe and mapping the corresponding serving cell. Taking the effective measurement subframe 0 of the neighboring cell 1 in fig. 8 as an example, the mapping corresponds to the subframe 1 and the subframe 2 of the serving cell, and then the terminal device determines that the subframe 1 of the serving cell is the radio frequency on time, and the sum (2ms) of the lengths of the subframe 1 and the subframe 2 of the serving cell is the radio frequency duration.

In an application scenario, when the terminal device performs alternate measurement on adjacent cells at different frequency points at the same time, first information of each adjacent cell corresponding to each frequency point needs to be stored (synchronization deviation between any two adjacent cells under the same frequency point or the first information includes an effective measurement subframe set of at least one adjacent cell), and then a target receiving mode of an effective measurement subframe can be determined according to the first information of each adjacent cell corresponding to each frequency point, wherein the target receiving mode of the effective measurement subframe corresponds to each frequency point. For example, the terminal device needs to measure reference signals of the neighboring cell 1, the neighboring cell 2, the neighboring cell 3, and the neighboring cell 4 at the same time, where the neighboring cell 1 and the neighboring cell 2 are at the frequency point 1, and the neighboring cell 3 and the neighboring cell 4 are at the frequency point 2. The terminal device may refer to the foregoing step S301 to step S303 or step S601 to step S605 to determine a target receiving mode 1 and a target receiving mode 2 of the valid measurement subframe, where the target receiving mode 1 is used to receive the valid measurement subframes of the neighboring cell 1 and the neighboring cell 2 corresponding to the frequency point 1, and the target receiving mode 2 is used to receive the valid measurement subframes of the neighboring cell 3 and the neighboring cell 4 corresponding to the frequency point 2.

Therefore, by such a receiving method, under the condition that the effective measurement subframes of the neighboring cells are dense, that is, when the ratio between the total duration of the terminal device and the total duration of the radio frequency on is close to a certain expected value, the smaller the expected value is, the closer the total duration of the terminal device and the total duration of the radio frequency on is, and at this time, the power consumption of the terminal device increased by such a receiving method is far less than the power consumption saved by saving the software computation complexity of the terminal device. Therefore, by the target receiving mode, the power consumption of the terminal equipment can be reduced, and the performance of the terminal equipment is improved.
