Among them, wearable devices can also be called wearable smart devices, which are the general term for using wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories.

Its main technical feature is to connect objects to the network through communication technology, so as to realize the intelligent network of human-machine interconnection and interconnection of things.

It should be understood that this application does not limit the specific form of the terminal device.

The network device in the embodiment of the present application may be any device with a wireless transceiver function. This equipment includes but is not limited to: evolved node B (evolved node B, eNB), radio network controller (RNC), node B (node B, NB), base station controller (base station controller, BSC) , Base transceiver station (BTS), home base station (for example, home evolved nodeB, or home node B, HNB), baseband unit (BBU), wireless fidelity (WIFI) system Access point (access point, AP), wireless relay node, wireless backhaul node, transmission point (transmission point, TP) or transmission and reception point (transmission and reception point, TRP), etc., can also be 5G (such as NR) The gNB or transmission point (TRP or TP) in the system, or one or a group of antenna panels (including multiple antenna panels) of the base station in the 5G system, or the network nodes that constitute the gNB or transmission point, such as Baseband unit (BBU), or distributed unit (DU), etc.

In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU for short). CU implements some functions of gNB, and DU implements some functions of gNB. For example, CU is responsible for processing non-real-time protocols and services, implementing radio resource control (RRC), and packet data convergence protocol (PDCP) The function of the layer. The DU is responsible for processing the physical layer protocol and real-time services, and realizes the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. AAU realizes some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by the DU , Or, sent by DU+AAU. It can be understood that the network device may be a device that includes one or more of a CU node, a DU node, and an AAU node. In addition, the CU can be divided into network equipment in an access network (radio access network, RAN), and the CU can also be divided into network equipment in a core network (core network, CN), which is not limited in this application.

The network equipment provides services for the cell, and the terminal equipment communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network equipment, and the cell may belong to a macro base station (for example, a macro eNB or a macro gNB, etc.) , It may also belong to the base station corresponding to the small cell, where the small cell may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmit power, and are suitable for providing high-speed data transmission services.

For the convenience of description, the following briefly introduces the terms involved in this application.

1. Paging

Paging means that the network can contact terminal devices in radio resource control (radio resource control, RRC) idle state or RRC inactive state (inactive state) through paging messages, and can receive system message changes through short messages. , Earthquake and tsunami warning system instruction information. Paging messages and short messages are scrambled by the paging-radio network temporary identity (P-RNTI) and carried on the physical downlink control channel (PDCCH) or physical downlink shared channel (physical downlink). shared channel, PDSCH).

2. Discontinuous reception (DRX)

When the terminal equipment in the idle state listens to the paging initiated by the core network (CN), and the terminal equipment in the inactive state listens to the paging initiated by the radio access network (RAN), the terminal equipment does not need to continuously monitor The channel that carries the paging message, that is, the terminal device uses the discontinuous reception (DRX) mechanism to monitor the paging message. When using DRX, a terminal device in the RRC idle state or RRC inactive state only monitors paging messages at one Paging opportunity in a DRX cycle. Among them, the DRX cycle is configured by the network device for the terminal device.

3. Measurement relaxation state of channel state measurement

When the terminal device does not enter the measurement relaxed state, it needs to measure the channel state of the serving cell and evaluate the cell selection S criterion of the serving cell at least once every M DRX cycle. The cell selection S criterion is used to determine whether the conditions for selecting a cell are met, where , M is an integer greater than 0. For example, the terminal device obtains the measurement value of the channel state by measuring the synchronization signal or the reference signal sent by the serving cell, and filters at least two measurement values every M DRX cycles to obtain the evaluation value of the channel state of the serving cell, where the at least The two measured values are separated by at least half of the DRX cycle. The terminal equipment then determines whether the cell selection S criterion is satisfied according to the estimated value of the channel state. Both the measurement value and the evaluation value may reflect the channel state of the serving cell, or the channel state includes the measurement value and/or the evaluation value.

In order to further reduce the power consumption of the terminal device due to measurement, a relaxation measurement method is proposed. When the terminal device uses the relaxation measurement method, it can be said to be in a relaxation measurement state or a measurement relaxation state. The terminal equipment that enters the measurement relaxed state performs a measurement or evaluation of the channel state of the serving cell within N*M DRX cycles (or integer multiples of DRX cycles), or performs at least two measurements and performs an evaluation to achieve savings The purpose of terminal equipment power consumption, where N is an integer greater than 1. The length of time for measuring the relaxed state may be pre-configured by the network device, for example, N*M DRX cycles. In one implementation method, the terminal device starts a timer when it enters the measurement relaxed state, the duration of the timer is N*M DRX cycles, and the terminal device does not measure the channel state of the serving cell during the running of the timer. When the timer expires, the terminal device measures the channel state of the serving cell, and if the measurement relaxation condition is met, it maintains or enters the measurement relaxation state, otherwise, it exits the measurement relaxation state.

Due to the uncertainty of the movement of the terminal device, for example, the terminal device is in a state of small displacement or a static state for a period of time, and at this time the terminal device enters the measurement relaxed state of the serving cell. If the terminal device suddenly starts to move but still maintains a measurement relaxed state, it may cause the terminal device to delay cell selection or reselection due to the inability of the terminal device to perform the serving cell measurement in time, thereby affecting the communication quality of the terminal device. This application proposes that a terminal device in the measurement relaxation state determines the first value of the first signal by detecting the first signal used to receive paging messages or system messages, and then determines whether to exit the measurement relaxation state according to the first value, to Realize the purpose of exiting the measurement relaxed state in time, and measuring the channel state of the serving cell in time, ensuring that the terminal equipment normally performs cell selection or reselection, and improving the communication reliability of the terminal equipment.

Fig. 2 shows an exemplary flow chart of a wireless communication method provided by an embodiment of the present application.

S210: The terminal device enters the measurement relaxed state of the channel state measurement of the serving cell.

When the terminal device does not enter the measurement relaxed state, it needs to measure the channel state of the serving cell and evaluate the cell selection S criterion of the serving cell at least once every M DRX cycles. The cell selection S criterion is used to determine whether the conditions for selecting a cell are met. The terminal device needs to filter at least two channel state measurement values to obtain an evaluation value, and the at least two measurement values are separated by at least half of the DRX cycle.

The terminal device measures the channel state of the serving cell, and the terminal device determines to enter the measurement relaxed state of the channel state measurement of the serving cell according to the measured value of the channel state.

For example, as shown in Figure 3, when the terminal device does not enter the measurement relaxed state, it normally measures the channel state of the serving cell, that is, measures the synchronization signal or reference signal sent by the network device once in each DRX cycle T to obtain the measurement value. In other words, the terminal equipment performs channel state measurement with a period of T. The terminal device enters the measurement relaxed state according to the result of the channel state measurement, and does not measure the channel state in the first time interval, that is, extends the period of the channel state measurement. For example, the first time interval in Figure 3 is nearly 4 DRX cycles, that is, the terminal device does not perform channel state measurement after T measurement to 5T, that is, the terminal device is at T, 5T, 9T (not shown in the figure) Wait for the channel state measurement, the measurement period is changed from T before the measurement relaxation to 4T.

S220: The network device sends the first signal to the terminal device.

The terminal device receives the first signal from the network device. As an example and not limitation, the first signal may be one or more of the following:

PDCCH, PDSCH, first DMRS used to demodulate PDCCH, and second DMRS used to demodulate PDSCH.

Wherein, the PDCCH may be used to carry the DCI of the scheduling paging message, or the PDCCH may be used to carry the DCI of the scheduling system message. The PDSCH can be used to carry paging messages, or the PDSCH can be used to carry system messages, but the application is not limited thereto.

According to the solution of the present application, a terminal device that enters a relaxed state for measurement relaxes a signal that can reflect the channel state (for example, a synchronization signal or a reference signal), but can pass the received first paging message and/or system message. Use one signal to estimate the channel state of the serving cell, determine whether to exit the measurement relaxation state, and exit the measurement relaxation state when the channel state is estimated to be worse through the first signal, so that the channel state of the serving cell can be measured in time to improve the reliability of communication sex.

S230: The terminal device determines the first value of the first signal.

The first value can be a measurement value obtained by the terminal device measuring the first signal, or an evaluation value of the first signal calculated based on the measurement value of the first signal, or it can be determined by other methods and can reflect the first signal. The strength or the evaluation value that can reflect the channel state, this application does not limit the method and means for determining the first value, for example, the evaluation value of the first signal is obtained by the measurement value of the first signal through filtering operation.

As an example and non-limiting, the first value is one or more of the following parameter values: the number of repeated receptions of the first signal, reference signal receiving power (RSRP), reference signal receiving quality (reference signal) receiving quality, RSRQ), received signal strength indication (RSSI), signal to interference plus noise ratio (SINR), signal noise ratio (SNR), successful detection repetition The number of times, coverage enhancement level, downlink radio link block error rate, and the link level at which the hypothetical PDCCH can be reliably received with a specific block error rate.

The first value may be referred to as a measurement value of the first signal, an evaluation value of the first signal, a channel state estimation value, a state value, or a parameter value, which is not limited in this application.

S240: The terminal device determines according to the first value to change the period of detecting the channel state of the serving cell from the first period to the second period, where the second period is smaller than the first period.

In other words, the terminal device determines to perform channel state measurement in a smaller cycle according to the first value. Specifically, before the terminal device enters the measurement relaxed state of the channel state measurement of the serving cell, the channel state measurement is performed in the second cycle. After the terminal device enters the measurement relaxed state of the channel state measurement of the serving cell, the channel state measurement is performed according to the first period. Since the first period is greater than the second period, the number of measurements performed by the terminal device can be reduced, thereby reducing the power consumption of the terminal device. For example, the second cycle is M DRX cycles, and the first cycle is N*M DRX cycles, where M is an integer greater than 0, and N is an integer greater than 1. The terminal device reduces the number of measurements in the relaxed state of measurement, but the terminal device cannot determine the channel state in time. In order for the terminal device to estimate the channel state, in this application, the terminal device can estimate the service by detecting the signal related to the paging message system message The channel state of the cell, and then determine whether to exit the measurement relaxed state. According to the solution of the present application, the terminal device that enters the measurement relaxed state relaxes the signal (for example, synchronization signal or reference signal) that can reflect the channel state, but can pass the first signal related to the paging message or system message (for example, bearer The first value of the PDCCH of the DCI, the PDSCH that carries the paging message or the system message, the first DMRS or the second DMRS) is used to estimate the channel state of the serving cell, determine whether to exit the measurement relaxation state, and use the first signal to estimate the channel state change. In the case of bad conditions, exit the measurement relaxed state in time, reduce the period of measuring the channel state of the serving cell, and obtain channel state information in time to improve the reliability of communication. For example, through one of the PDCCH used to carry DCI for scheduling paging messages or system messages, the PDSCH used to carry paging messages or system messages, the DMRS used to receive the above-mentioned PDCCH, or the DMRS used to receive the above-mentioned PDSCH, or The first values of various signals are used to estimate the channel state of the serving cell, so that the terminal device can exit the measurement relaxed state in time, and then perform the channel state measurement of the serving cell in time to ensure the reliability of the communication of the terminal device.

After determining the first value, the terminal device compares the first value with the first threshold value, and/or compares the difference between the first value and the reference value with the second threshold value, and determines whether to exit according to the comparison result Measure the relaxed state, or determine whether to change the period of measuring the channel state from the first period to the second period according to the result of the comparison. The reference value may be the first value obtained by the terminal device last time measuring the first signal, that is, the first value obtained by the terminal device last time receiving the first signal. Or the reference value may be sent by the network device to the terminal device or pre-configured in the terminal device, but the present application is not limited to this.

As an example and not limitation, the second period may be a DRX period, or a period for measuring the channel state in a non-measurement relaxed state sent by the network device to the terminal device.

In one embodiment, the first value is the number of repetitions required for the terminal device to successfully detect the first signal (denoted as the number of repetitions of successful detection). The network device sends the first signal in a repeated sending manner, that is, the network device continuously sends the first signal repeatedly, and the terminal device can determine whether to exit the measurement relaxation state according to the number of repetitions required to successfully detect the first signal.

In this application, exiting the measurement relaxed state can be understood as changing the period of measuring the channel state from the first period to the second period.

For example, if the network device repeatedly sends the first signal, and the terminal device successfully detects the first signal once in the DRX cycle, the first value is 1, that is, the terminal device successfully detects the first signal. The number of repetitions is 1; if the terminal device detects the first signal after two detections, the first value is 2; if the terminal device detects the first signal after three detections, the first value is 3. If the terminal device detects the first signal for the maximum number of times that the network device repeatedly sends the first signal and fails to detect the first signal, the terminal device determines that the detection of the first signal fails, and the terminal device determines that it has not acquired a valid first value , And then do not judge whether to exit the measurement relaxed state.

After the terminal device detects the first signal and determines the number of successful detection repetitions, it can determine whether to exit the measurement relaxation state by the following three methods, or determine whether to change the period of measuring the channel state from the first period to the first period by the following three methods: Two cycles, where the first cycle is greater than the second cycle. It should be noted that the following three methods are only examples. In specific implementation, the terminal device may determine whether to exit the measurement relaxed state or determine whether to change the period of measuring the channel state according to the first value and the first threshold value.

method one

If the number of successful detection repetitions is greater than or equal to the first threshold, the terminal device determines to exit the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period. After the terminal device enters the measurement relaxed state, it measures the channel state of the serving cell once in the first cycle, and detects the first signal at least twice. If the first signal is detected and the number of successful detection repetitions is determined, if the number of successful detection repetitions is greater than or If it is equal to the first threshold value, it is determined to exit the measurement relaxed state, and the period for measuring the channel state of the serving cell is changed from the first period to the second period, where the first period is greater than the second period.

According to the solution of the present application, when the number of successful detection repetitions is greater than or equal to the first threshold, the terminal device exits the measurement relaxed state and starts to measure the channel state of the serving cell in a smaller period, which can reduce the sudden change of the terminal device due to the channel state. The probability of changing without timely cell reselection, thereby improving the reliability of terminal equipment communication.

In a possible implementation manner, the first signal is a first PDCCH, and the first PDCCH is used to carry DCI for scheduling paging messages. The terminal device determines whether to exit the measurement relaxation state of the channel state measurement by successfully receiving or decoding the number of repetitions of the first PDCCH. Taking Figure 4 as an example, the terminal device measures the channel state of the serving cell at time 0 and determines to enter the measurement relaxed state. After that, the terminal device performs the channel state measurement of the serving cell on a 7T cycle, that is, the channel state of the serving cell is not measured for six measurement opportunities in the first time interval from the measurement at time 0 to the first time before the 7T measurement. The terminal device monitors a paging message once in each DRX cycle. If the network device sends a paging message or PDCCH scrambled by P-RNTI, the paging message or the PDCCH may not be sent for the terminal device, and the terminal device may The DMRS used to decode the PDCCH is detected, and the PDCCH may be demodulated. If the PDCCH schedules a paging message, the terminal device can decode the paging message. At this time, the terminal device can determine whether to exit the measurement relaxation state according to the number of successful detection repetitions of one or more of the following signals (1) to (4):

(1) Successfully parse out the number of repetitions required to decode the first DMRS of the PDCCH, or

(2) The number of repetitions required to successfully decode the PDCCH, or

(3) Successfully parse out the number of repetitions required to decode the second DMRS of the PDSCH carrying the paging message, or

(4) The number of repetitions required to successfully decode the PDSCH carrying the paging message.

As shown in FIG. 4, the terminal device detects the PDCCH or paging message scrambled by the P-RNTI sent by the network device between T and 2T, and between 5T and 6T. For example, the number of repetitions of the first signal sent by the network device is 3, and the number of repetitions (ie, the first value) required for the terminal device to successfully detect the first signal between T and 2T is less than the first threshold, such as the first threshold The value is 2, and the number of repetitions (ie, the first value) required for the terminal device to successfully detect the first signal is 1, and the terminal device maintains the measurement relaxed state. The network equipment does not send paging messages or P-RNTI scrambled PDCCH between 2T and 3T, 3T and 4T, 4T and 5T, or the terminal equipment does not detect a paging message or P-RNTI scrambled within the above time PDCCH, the terminal device does not perform measurement or does not need to determine the number of successful detection repetitions (ie the first value). The terminal device can consider that there is no valid number of successful detection repetitions at this time, that is, there is no valid first value. The first value is compared with the first threshold value, and the terminal device keeps the measurement relaxed state. Between 5T and 6T, the network device sends the first signal, and the terminal device detects the first signal and determines the first value of the first signal. For example, the first value is the number of successful detection repetitions. If the first value is greater than or Equal to the first threshold value. If the first threshold value is 2, the number of repetitions required for the terminal device to successfully detect the first signal between 5T and 6T is 3, that is, the first value is 3, and the first value is greater than the first value. A threshold value. At this time, the terminal device exits the measurement relaxation state and starts to perform channel state measurement. For example, the terminal device starts to perform channel state measurement according to the DRX cycle after 6T, that is, the terminal device changes the period of measuring the channel state from 7T to T. The time interval for measuring the channel state is the second period, and the second period may be T, or the time interval for measuring the channel state after exiting the measurement relaxed state pre-configured by the network device for the terminal device. The terminal device periodically measures the channel state of the serving cell in a second period after exiting the measurement relaxed state. Optionally, the period may be a period for the terminal device to measure the channel state before entering the measurement relaxed state. It should be noted that FIG. 4 takes as an example the first signal being repeatedly sent multiple times on time resources. The first signal may also be repeatedly sent multiple times on frequency resources, or repeated on time-frequency resources or spatial resources. Send multiple times, this application is not limited.

In another possible implementation manner, the first signal is a second PDSCH carrying system messages, and the system messages may be system messages received by the terminal device when the paging message indicates the system message change. This application does not Limited to this. After the terminal device enters the measurement relaxation state, it measures the channel state in a longer period, and determines whether to exit the measurement relaxation state according to the number of repetitions required to successfully receive the second PDSCH (recorded as the number of successful detection repetitions). When it is equal to the first threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period.

Way two

In the case that the difference between the number of repetitions required to successfully detect the first signal (denoted as the number of repetitions of successful detection) and the reference value of the number of repetitions of successful detection is greater than or equal to the second threshold value, the terminal device determines to exit the measurement relaxation state , Change the period of measuring the channel state from the first period to the second period. The reference value may be the number of repetitions required for successfully detecting the first signal determined last time by the terminal device, or the reference value may be sent by the network device to the terminal device or a pre-configured value of the terminal device.

According to the solution of the present application, the terminal device determines whether to exit the measurement relaxation state according to the difference between the first value of the first signal and the reference value, that is, when the difference is greater than or equal to the second threshold value, exit the measurement relaxation state, It can reduce the probability that the terminal device does not perform cell reselection in time due to sudden changes in the channel state, and can improve the reliability of the communication of the terminal device.

For example, the first signal is the first PDSCH, that is, the first signal is the PDSCH that carries the paging message. The terminal device determines the number of repetitions required to successfully detect (or receive) the first PDSCH (denoted as the number of repetitions of successful detection), and determines the difference between the number of repetitions of successful detection and the reference value, where the difference is greater than or equal to the second In the case of the threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period. Taking FIG. 4 as an example, the first signal in FIG. 4 is the first PDSCH carrying the paging message, and the terminal device determines to enter the measurement relaxed state according to the measured channel state at time 0. The terminal device successfully receives the first PDSCH between T and 2T, and determines that the number of repetitions required to successfully receive the first PDSCH (denoted as the number of repetitions for successful detection) is X. The terminal device determines that the difference |X-Y| between the number of successful detection repetitions X and the reference value Y is less than the second threshold value, and the terminal device maintains the measurement relaxed state. However, between 5T and 6T, the terminal device successfully receives the first PDSCH again, and determines that the difference between the number of successful detection repetitions Z and the parameter value Y |ZY| is greater than or equal to the second threshold, and the terminal device exits the measurement relaxed state, The period for measuring the channel state is changed from the first period to the second period. That is, the terminal device starts to measure the channel state of the serving cell with a period T after exiting the measurement relaxed state, that is, the second period is T, and the second period may also be sent by the network device to the terminal device. Optionally, the period may be the period for measuring the channel state before the terminal device enters the measurement relaxed state. In this example, the reference value may be the first value of the first signal determined for the first time after the terminal device enters the measurement relaxed state, and the reference value may also be a value sent by the network device to the terminal device or a value pre-configured by the terminal device. value. Or, the reference value is the first value of the first signal determined last time.

In this application, the first signal may also be a DMRS used to demodulate the first PDCCH (that is, an example of the first DMRS), the first PDCCH or a DMRS used to demodulate the first PDSCH (that is, an example of the second DMRS). ). For specific implementation manners, reference may be made to the above description, and for the sake of brevity, it will not be repeated here.

It should be noted that FIG. 4 takes as an example the first signal being repeatedly sent multiple times on time resources. The first signal may also be repeatedly sent multiple times on frequency resources, or repeated on time-frequency resources or spatial resources. Send multiple times, this application is not limited.

Way three

In the case that the number of repetitions required to successfully detect the first signal is greater than or equal to the first threshold, and the difference between the number of repetitions of successful detection and the reference value is greater than or equal to the second threshold, the terminal device determines to exit the measurement relaxation State, the period of measuring the channel state is changed from the first period to the second period. For specific implementation manners, reference may be made to the above description of the manner one and manner two, and for the sake of brevity, the details are not repeated here.

According to the solution of the present application, the terminal device determines that the first value of the first signal is greater than or equal to the first threshold value, and the difference between the first value and the reference value is greater than or equal to the second threshold value, combining two conditions to determine Exiting the measurement relaxed state can reduce the probability that the terminal device does not perform cell reselection in time due to a sudden change in the channel state, and can improve the reliability of the communication of the terminal device.

In another embodiment, the first value may be one or more of the following (1) to (7) parameter values:

(1) Measure the received power of the first signal, for example, measure the RSRP of the first signal.

(2) Measure the reception quality of the first signal, for example, measure the RSRQ of the first signal.

(3) Measure the signal-to-interference and noise ratio of the first signal, for example, measure the SINR of the first signal.

(4) Measure the signal-to-noise ratio of the first signal, for example, measure the SNR of the first signal.

(5) Determine the downlink radio link level for reliable reception of hypothetical PDCCH transmission with a block error rate of 10%.

(6) The wireless link level for reliable reception of the assumed PDCCH.

(7) The wireless link level that reliably receives the first signal.

After the terminal device enters the measurement relaxation state, it receives the first signal, measures the first value of the first signal, and compares the first value with the first threshold value, and/or compares the first value with the reference The difference between the value and the second threshold value is determined according to the result of the comparison whether to exit the measurement relaxed state, and the period of measuring the channel state is changed from the first period to the second period, where the first period is greater than the second period .

For example, as shown in Figure 5, the first signal is a DMRS used to demodulate the first PDCCH (that is, an example of the first DMRS). The terminal device determines to enter the measurement relaxed state according to the channel state measurement at time 0, and does not measure before time 7T. The channel status of the serving cell. The terminal device monitors the paging message in each DRX cycle, the terminal device determines the first value of the first signal according to the received first signal, and determines whether to exit the measurement relaxation state according to the first value, for example, the first value is the RSRP value .

The terminal device may determine whether to exit the measurement relaxed state according to the following three methods, so as to change the period of measuring the channel state from the first period to the second period, where the first period is greater than the second period.

method one

In the case that the first value of the first signal is less than or equal to the first threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period.

For example, as shown in Figure 5, the terminal device detects the first DMRS between 3T and 4T, and the measured RSRP value of the first DMRS, and the RSRP value is greater than the first threshold, there is no need to exit the measurement relaxation state. Between 4T and 5T, if the RSRP value of the first DMRS measured by the terminal device is less than or equal to the first threshold, the terminal device exits the measurement relaxed state and changes the period of measuring the channel state from the first period to the second period . For example, the first period is 7T, and the second period is T. After exiting the measurement relaxed state, the terminal device changes the period of measuring the channel state to a second period, for example, the second period is T, and the channel state of the serving cell is periodically measured in the second period. Optionally, the second period may be a period for measuring the channel state before the terminal device enters the measurement relaxed state or a period sent by the network device to the terminal device.

Way two

In the case where the difference between the first value of the first signal and the reference value is greater than or equal to the second threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period.

For example, as shown in Figure 5, the terminal device detects the first DMRS between 3T and 4T, and determines that the difference between the RSRP value (denoted as P) of the first DMRS and the parameter value Q |PQ| is less than the second gate Limit, the terminal device keeps the measurement relaxed state. When the difference between the RSRP value W of the first DMRS and the reference value Q measured by the terminal device between 4T and 5T |WQ| is greater than or equal to the second threshold, the terminal device exits the measurement relaxed state and will measure the channel The period of the state is changed from the first period to the second period, and the channel state of the serving cell is measured with the second period as the period from exiting the measurement relaxed state.

Way three

In the case that the first value of the first signal is less than or equal to the first threshold value, and the difference between the first value and the reference value is greater than or equal to the second threshold value, the terminal device exits the measurement relaxed state and will measure The cycle of the channel state changes from the first cycle to the second cycle. For specific implementation manners, reference may be made to the above description of the manner one and manner two, and for the sake of brevity, the details are not repeated here.

In this application, the first signal may also be the first PDCCH, the first PDSCH, the DMRS used to demodulate the first PDSCH (that is, an example of the second DMRS), the second PDCCH, the second PDSCH, and the demodulation The DMRS of the second PDCCH (that is, another example of the first DMRS), and the DMRS used to demodulate the second PDSCH (that is, an example of the second DMRS). For specific implementation manners, reference may be made to the above description, and for the sake of brevity, it will not be repeated here.

Optionally, the network device sends first information to the terminal device, where the first information includes the first period and/or the second period. As an example and not a limitation, the first information may be at least one of an RRC message sent by a network device to a terminal device, a media access control control element (MAC-CE), or DCI.

In this application, the first threshold value and/or the second threshold value may be a threshold value sent by the network device to the terminal device, or may be a threshold value pre-configured by the terminal device. For example, the network device sends second information to the terminal device, the second information includes the first threshold value and/or the second threshold value, and the second information is used to indicate the first threshold value and/or the second threshold value. The first threshold value and/or the second threshold value are used by the terminal device to determine whether to exit the measurement relaxation state, or the first threshold value and/or the second threshold value are used by the terminal device to determine whether The period for measuring the channel state is changed from the first period to the second period.

As an example and not a limitation, the second information may be a system message sent by the network device to the terminal device.

Optionally, the second information may also be used to indicate the third threshold value and/or the fourth threshold value, and the third threshold value and/or the fourth threshold value may be used for the terminal device to determine the entry measurement relaxation state. The third threshold value and/or the fourth threshold value may also be indicated by information other than the second information, which is not limited in this application.

According to the solution of the present application, after the terminal device in the measurement relaxed state detects the first signal for receiving the paging message or the system message, it determines the first value of the first signal, and determines whether or not according to the first value of the first signal Exiting the measurement relaxed state can reduce the probability that the terminal device does not perform cell reselection in time due to sudden changes in the channel state, so as to improve the reliability of the terminal device communication.
