Detailed Description
The present application is described in further detail below with reference to examples and figures. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the invention are shown in the drawings.
It should be noted that, without conflict, the embodiments herein, i.e., features of the embodiments, may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The terms referred to in this application are explained first.
(1) The 3GPP (3 rd Generation Partnership Project, third generation partnership project) is a communication protocol standard organization that can formulate communication protocol specifications. The above-mentioned communication protocol specification may be, for example, 3gpp 38.331.
(2) mmWave (millimeter wave) is an electromagnetic wave with the frequency above 24GHz, and can be applied to wireless communication technology, so that the data transmission rate can be greatly improved, the time delay can be shortened, and the frequency bandwidth can be widened.
(3) MIMO wireless communication antenna technology is SM (Spatial Multiplexing ), which is one mode of operation of antennas. In particular, spatial multiplexing may be a mode of operation in which multiple antennas are used in space for data stream transmission. For example, multiple antennas may transmit and receive electromagnetic waves of the same frequency in multiple data streams.
(4) The ENDC dual connectivity technology (Evolved-utran New radio Dual Connectivity, evolved access network new air interface dual connectivity) is one application scenario for communication between a UE and a base station. The ENDC dual-connection technology is a network connection mode taking a 4G LTE network as a main part and a 5G NR network as an auxiliary part. The cell group where the UE first initiates the random connection is MCG (Master Cell Group, primary cell group) and the other cell group is SCG (Secondary Cell Group ). Within the master Cell group MCG, the Cell where the UE first initiates random connection is a PCell (Primary Cell), and the remaining cells are scells (Secondary cells). The primary cell PCell and the secondary cell SCell are combined together through a CA (Carrier Aggrecation) technology, so that the frequency bandwidth is increased when the UE and the base station communicate, and the data transmission rate in the communication process of the UE and the base station is improved.
(4) The carrier aggregation CA technology is a wireless communication technology, and can aggregate carriers of a plurality of cells together, thereby improving the bandwidth at the time of data transmission.
In the prior art, when the power consumption of the user terminal is larger due to the communication with the base station, no feasible mode is available for reducing the power consumption of the user terminal, and the operation effect of the user terminal is seriously affected.
Therefore, a scheme for reducing the power consumption of the user terminal is needed.
Based on the above, the present application provides a channel parameter adjustment method, and by adopting the method of the present application, the power consumption of the user terminal can be reduced.
Specifically, the channel parameter adjustment method provided by the application can be applied to an application scenario as shown in fig. 1. Referring to fig. 1, the application scenario may include a user terminal 10 and an access network device 20. The user terminal 10 may send a message to the access network device 20. For example, the CSI (Channel State Information ) report is transmitted to the access network device 20, and the access network device 20 may make a corresponding action based on the received CSI report, thereby reducing power consumption of the user terminal 10.
In particular, the user terminal 10 may be a device for communication. For example, the device may be a UE (User Equipment). By way of example, the UE may be a smart phone, tablet, multimedia device, etc.
The access network device 20 may be an interface device that accesses the user terminal 10 to the internet. The interface device may be, for example, a base station. The base station may be a 4G base station eNB (evolved Node B) or a 5G base station gNB (generation Node B, next generation Node B), for example.
Fig. 1 above presents an application scenario diagram of the present application. In another embodiment of the present application, a channel parameter adjustment method is also provided, which can be applied to the application scenario shown in fig. 1 and executed by the access network device 20. Fig. 2 is a flow chart of the method. In particular, reference may be made to fig. 2, the method comprising the steps of:
step 201, an access network device receives a first channel parameter set sent by a user terminal; the first set of channel parameters comprises at least one channel parameter for characterizing a channel condition desired by the user terminal.
In this embodiment of the present invention, when the power consumption of the ue increases due to uplink and downlink communications with the access network device, the ue may report, to the access network device, a desired channel parameter for reducing the power consumption of the ue, that is, the access network device may adjust the channel parameter of the ue according to the channel parameter (i.e., the desired channel parameter) reported by the ue for reducing the power consumption of the ue. After the channel parameters of the user terminal are adjusted, the user terminal can be in a desired channel condition to communicate with the access network equipment, so that the power consumption of the user terminal is reduced.
In particular, the channel parameters may be parameters for characterizing the channel conditions between the user terminal and the access network device. In the embodiment of the application, the channel parameters sent by the user terminal can characterize the channel conditions expected by the user terminal. For example, the channel parameters may characterize the channel quality, the amount of resources occupied by the channel, and so on. The channel parameter may be, for example, a channel quality Indicator CQI (Channel Quality Indication, channel quality Indicator), or in a MIMO wireless communication antenna technology (Multiple Input Multiple Output ) scenario, the channel parameter may indicate the number of data streams occupied by a channel, for example, a Rank Indicator RI (Rank Indicator) for indicating the number of spatial data streams corresponding to an uplink channel or a downlink channel between the user terminal and the access network device.
It can be understood that when the channel parameter reported by the ue is a Rank Indicator RI (Rank Indicator). The value of the rank indication RI positively correlates with the number of the space data streams occupied by the channel, and the larger the rank indication RI is, the more the number of the data streams is. In addition, the rank indication RI is used to indicate the optimal layer number for the current channel transmission of the access network device. The Channel may be a DL-SCH Channel (DownLink-Shared Channel). The optimal number of layers for the above-described transmission may be the number of antennas employed to reduce the power consumption of the user terminal.
When the channel parameter reported by the user terminal is channel quality indicator CQI. The value of the channel quality indicator CQI is positively correlated with the channel quality, and the larger the channel quality indicator CQI is, the better the channel quality is. The value range of the channel quality indication CQI is any integer from 0 to 15.
In one possible implementation, if the first parameter set may be a channel state information CSI report, the channel state information CSI report may include a rank indication RI, a precoding matrix PMI, and a channel quality indication CQI. And, the channel state information CSI report may be sent to the access network device periodically or aperiodically. That is, the rank indication RI, the precoding matrix PMI, and the channel quality indication CQI may be periodically or aperiodically transmitted to the access network device.
The periodicity and aperiodicity are different from each other in the manner in which the channel state information CSI report is triggered to be transmitted. If the trigger mode of the CSI report is different, the ue may send the CSI report at a time interval (e.g., periodic or aperiodic) corresponding to the trigger mode. For example, if the triggering manner is that the base station (corresponding to the access network device) radio resource control eNB RRC (evolved Node BRadio Resource Control, base station radio resource control) configuration module configures the channel state information CSI report, the user terminal periodically sends the channel state information CSI report. If the trigger mode is that the downlink control information DCI0 (Downlink Control Information ) displays a transmission channel state information CSI report, the user terminal aperiodically transmits the channel state information CSI report.
In one possible implementation, the message carrying the first set of channel parameters (e.g., CSI report) may be considered as a special CSI report. When the CSI report may include a type indication field for indicating whether the currently transmitted CSI report contains channel parameters desired by the user terminal, i.e., whether the currently transmitted CSI report is a conventional CSI report. For example, the type indication field is "1" to indicate that the CSI report currently transmitted includes the channel parameter expected by the user terminal, that is, the channel parameter for reducing the power consumption transmitted by the user terminal when the power consumption is higher; conversely, a type indication field of "0" indicates that the CSI report currently transmitted does not include the channel parameters expected by the user terminal, is a conventional CSI report, and may include some channel parameters obtained by the user terminal performing channel measurement.
In addition, the CSI report may include a plurality of different fields for respectively indicating different channel parameters and channel conditions.
In another possible implementation, the message carrying the first parameter set may also be transmitted through a specific uplink channel (e.g., carrier). For example, a recipient (e.g., an access network device) may receive data transmitted over the particular upstream channel. In this manner, the message may not include the type indication field, and the access network device may identify, through a channel for receiving the message, that the message includes the channel parameter desired by the user terminal.
Alternatively, the message carrying the first parameter set may be encoded by a specific encoding method. For example, the receiver may receive data transmitted after being encoded using a particular encoding scheme. In this manner, the message may not include the type indication field, and the access network device may identify that the message includes the channel parameter expected by the user terminal through the coding manner of the message.
Step 202, the access network device adjusts channel parameters of the user terminal based on the first channel parameter set, wherein the adjusted channel parameters are used for reducing power consumption of the user terminal.
In one possible implementation, the access network device may receive the channel parameter for reducing the power consumption of the user terminal, and adjust the channel parameter of the user terminal based on the channel parameter for reducing the power consumption of the user terminal, where after the channel parameter is adjusted, the power consumption of the user terminal is reduced when the user terminal and the access network device communicate again.
The channel parameters for reducing the power consumption of the ue may be either one of rank indication RI of 2 or channel quality indication CQI of 6 or a combination of both. The access network device may adjust the number of antennas of the ue to 2 according to the rank indication RI of 2, or may adjust the number of modulation coding stages of the radio signal of the ue to a corresponding number of stages according to the channel quality indication CQI of 6.
Alternatively, the access network device may adjust the rank indication RI to 2 according to the rank indication RI of 2, and then adjust the number of antennas of the ue to 2 according to the rank indication RI of 2, or may adjust the channel quality indication CQI to 6 according to the channel quality indication CQI of 2, and then adjust the modulation coding level of the radio signal to the ue to a corresponding level according to the channel quality indication CQI of 6.
In summary, in the solution of the present application, the ue may perform self-power consumption detection, and generate, based on the result of the power consumption detection, a channel parameter for reducing self-power consumption, that is, an expected channel parameter. Further, the ue may send the channel parameter for reducing its own power consumption to the access network device, and the access network device may receive the channel parameter for reducing its power consumption, and adjust the channel parameter of the ue based on the channel parameter for reducing its power consumption, thereby reducing its power consumption.
And because the user terminal sends the channel parameters for reducing the power consumption of the user terminal to the access network equipment, the access network equipment can adjust the channel parameters of the user terminal based on the channel parameters for reducing the power consumption of the user terminal, thereby reducing the power consumption of the user terminal.
Therefore, by adopting the scheme of the application, the power consumption of the user terminal can be reduced.
And because the user terminal sends the channel parameters for reducing the power consumption of the user terminal to the access network equipment, the access network equipment can adjust the channel parameters of the user terminal based on the channel parameters for reducing the power consumption of the user terminal, thereby reducing the power consumption of the user terminal. In addition, by adopting the scheme, the problem that in the prior art, when the power consumption of the user terminal is large, no feasible mode is used for reducing the power consumption of the user terminal is solved.
Therefore, by adopting the scheme of the application, the power consumption of the user terminal can be reduced.
In the foregoing embodiments, a channel parameter adjustment method is described. In another embodiment of the present application, it is presented how to adjust the channel parameters of a user terminal in particular when the channel parameters are used to characterize the number of spatial transport streams desired by the user terminal. For example, the specific implementation of the "access network device adjusts channel parameters of the user terminal based on the first set of channel parameters" related to the previous step includes the steps of fig. 3:
step 301, determining the number of transmission antennas with the user terminal based on the number of spatial transmission streams.
In particular, the number of spatial transport streams is used to characterize the number of data streams in space for the transmission of data. The number of data streams may be, for example, the number of data streams for reducing power consumption of the user terminal. For example, the number of data streams for reducing the power consumption of the user terminal may be 2.
The number of transmit antennas is used to characterize the number of transmit antennas and receive antennas of the user terminal. The number of transmit antennas and receive antennas may be, for example, the number of antennas used to reduce power consumption of the user terminal. For example, the number of antennas used to reduce the power consumption of the ue may be 2×2, and 2×2 is used to characterize that the number of transmitting antennas and receiving antennas of the ue in the MIMO wireless communication antenna technology is 2.
In one possible implementation, the number of data flows that the user terminal sends to reduce the power consumption of the user terminal is 2, and the number of data flows that the access network device receives to reduce the power consumption of the user terminal is 2. Since the number of data streams for reducing the power consumption of the user terminal is associated with the number of transmitting antennas and receiving antennas for reducing the power consumption of the user terminal, when the number of data streams for reducing the power consumption of the user terminal received by the access network device is 2, the number of transmitting antennas and receiving antennas for reducing the power consumption of the user terminal is adjusted to be 2, which may be abbreviated as 2×2.
Step 302, the current number of antennas is switched to the number of transmission antennas.
In particular, the current number of antennas is used to characterize the number of transmit and receive antennas that are currently being used by the user terminal. By way of example, the number of transmit antennas and receive antennas currently in use may both be 8, which may be abbreviated as 8 x 8.
In one possible implementation, the access network device may switch the number of transmit antennas and receive antennas currently being used by the user terminal to 8×8, and switch the number of transmit antennas and receive antennas used to reduce power consumption of the user terminal to 2×2, where when the number of transmit antennas and receive antennas of the user terminal is reduced, the data transmission rate of the user terminal may be reduced, thereby reducing power consumption of the user terminal.
In the embodiments described above, it is described how to adjust the channel parameters of a user terminal in particular when the channel parameters are used to characterize the number of spatial transport streams desired by the user terminal. In another embodiment of the present application, it is presented how channel parameters of a user terminal are specifically adjusted when they are used to characterize the channel quality desired by the user terminal. For example, the specific implementation of the "the access network device adjusts the channel parameters of the user terminal based on the first channel parameter set" related to the previous step includes:
And determining a modulation coding mode of a transmission channel between the user terminal and the base station based on the channel quality expected by the user terminal.
Specifically, the modulation coding mode may be to select an appropriate modulation coding level for the wireless signal in wireless communication, so that the wireless signal may be reliably transmitted in the wireless channel. When the channel quality is worse, the number of modulation and coding stages is selected to be lower, the data transmission rate of the user terminal is lower, and the power consumption of the user terminal is lower. Conversely, when the channel quality is better, the higher the modulation coding level is selected, the higher the data transmission rate of the user terminal is, and the higher the power consumption of the user terminal is.
In one possible implementation, the ue sends a channel quality indicator CQI for reducing the ue to 6, and the access network device may receive the channel quality indicator CQI for reducing the ue to 6. Since the channel quality indicator CQI is associated with the modulation coding scheme, when the channel quality indicator CQI is 6, the modulation coding scheme corresponding to the CQI of 6 can be obtained through table lookup, where the coding scheme includes a modulation order and a code rate, where the modulation order may be 16QAM, and the code rate may be 378.
It can be understood that when the channel quality is poor, the channel quality indicator CQI may be 6, and the modulation coding level corresponding to the CQI of 6 is lower, so that the lower the data transmission rate of the user terminal is, the power consumption of the user terminal may be reduced.
In the embodiments described above, it is described how to adjust the channel parameters of a user terminal in particular when the channel parameters are used to characterize the channel quality desired by the user terminal. In another embodiment of the present application, after the access network device adjusts the channel parameters of the user terminal based on the first channel parameter set, if the power consumption of the user terminal is not effective or significantly reduced, the configuration of the user terminal may be performed based on the carrier. For example, specific implementation of the access network device for configuring the user terminal based on the carrier wave includes:
and if the user equipment is configured with the main carrier and the auxiliary carrier, removing the auxiliary carrier of the user terminal.
Specifically, when the primary carrier is a carrier of the primary cell PCell used when the user terminal transmits data to the access network device. That is, the user terminal may transmit data to the access network device using the carrier of the primary cell PCell. Typically, one primary cell group MCG has 3 cells, one of which is the primary cell PCell and the other two are secondary cells scells.
The secondary carrier is a carrier of the secondary cell SCell used when the user terminal transmits data to the access network device. That is, the user terminal may transmit data to the access network device using the carrier of the secondary cell PCell.
The primary carrier and the secondary carrier may be uplink carriers, and if the user terminal uses a carrier to transmit data to the access network device, the carrier is an uplink carrier.
In one possible implementation manner, if the network combination mode with the 4G LTE as the primary network and the 5G NR as the secondary network is used for communication between the user terminal and the access network device, the 4G LTE is used as the primary cell group MCG. If the primary cell group MCG configures the primary cell PCell and the secondary cell SCell, and the primary cell PCell and the secondary cell SCell are aggregated together by a carrier aggregation CA technology, the primary carrier of the primary cell PCell and the secondary carrier of the secondary cell PCell can both fulfill the task that the user terminal uploads data to the access network device, and the user terminal can be prohibited from uploading data to the access network device by using the secondary carrier of the secondary cell PCell, so that the communication bandwidth between the user terminal and the access network device is reduced, and the power consumption of the user terminal is reduced.
In one possible implementation, if the ue uses the ENDC dual connectivity technology, when the ue consumes more power (e.g., the ue is at a higher temperature and is close to the temperature threshold), the ue may send a secondary cell group SCG connection failure message to the ue if the RRC reconnection fails. For example, the type of failure message set based on the protocol 38.331.5.7.3.3 may be t310-Expiry, t312-Expiry, ynchreconfirmfailure-SCG, rl-MaxNumRetx, SCG-reconfigfailure. The access network equipment can modify the ENDC double connection into single connection, namely, the communication between the user terminal and the access network equipment is completed based on the 4G LTE network, so that the power consumption caused by the user terminal completing the communication by adopting the ENDC double connection technology is avoided, and the power consumption of the user terminal is reduced.
In the foregoing embodiments, it is described that after the access network device adjusts the channel parameters of the user terminal based on the first channel parameter set, if the power consumption of the user terminal is not effective or significantly reduced, the user terminal may be configured based on the carrier. In another embodiment of the present application, a channel parameter adjustment method is introduced, which can be applied to the application scenario shown in fig. 1 and executed by a user terminal. Fig. 4 is a flow chart of the method. In particular, reference may be made to fig. 4, the method comprising the steps of:
step 401, a user terminal performs power consumption detection, and generates a first channel parameter set according to a power consumption detection result; the first set of channel parameters comprises at least one channel parameter for characterizing a channel condition desired by the user terminal.
In one possible implementation, the user terminal has a power consumption detector built-in. For example, the power consumption detector may be a temperature detector. The power consumption detector may detect a current temperature, a current battery power consumption, or a current wattage of the user terminal, determine whether the current temperature of the user terminal exceeds a preset temperature threshold, whether the current battery power consumption exceeds a preset power threshold, or whether the current wattage exceeds one or a combination of several of the preset current thresholds.
The result of the power consumption detection is used to characterize the power consumption level of the user terminal. For example, the power consumption degree of the user terminal may be one or several of a current temperature of the user terminal exceeding a preset temperature threshold, a current battery power consumption exceeding a preset power threshold, or a current wattage exceeding a preset current threshold.
In one possible implementation, when the current power consumption of the user terminal exceeds a preset power threshold, a channel parameter for reducing the power consumption of the user terminal is generated. The channel parameter may be, for example, the number of data streams for reducing the power consumption of the user terminal. The number of data streams may be 2, for example.
Step 402, a channel parameter set is sent to an access network device, where the channel parameter set is used to instruct the access network device to adjust channel parameters of a user terminal so as to reduce power consumption of the user terminal.
In one possible implementation, when the current power consumption of the user terminal exceeds a preset power threshold, the number of data streams for reducing the power consumption of the user terminal is generated and transmitted. The number of data streams may be 2, for example.
In one possible implementation, the access network device may receive 2 data flows for reducing power consumption of the user terminal, and since the number of data flows is associated with the number of antennas of the user terminal, the number of antennas of the user terminal may be modified to 2. It will be appreciated that 2 herein may characterize the number of transmit antennas and receive antennas of the user terminal as 2.
In the foregoing embodiments, a channel parameter adjustment method is described. In another embodiment of the present application, a specific type of channel parameters is presented. For example, the channel parameters are used to characterize the number of spatial transport streams desired by the user terminal and/or the channel parameters are used to characterize the channel quality desired by the user terminal.
It will be appreciated that for the explanation of the number of spatial transport streams, and the channel quality, reference is made to the foregoing, and no further description is given here.
In the embodiments described above, specific types of channel parameters are described. In another embodiment of the present application, a precondition for the user terminal to generate the first set of channel parameters is introduced. For example, the specific implementation of the step of generating the first channel parameter set according to the result of power consumption detection includes the steps of fig. 5:
step 501, the ue detects a current temperature, and if the current temperature exceeds a preset temperature threshold, determines at least one channel parameter for reducing power consumption.
Specifically, the user terminal may measure the temperature itself at this point in time. The temperature of the user terminal at this point may be, for example, 47 ℃.
The preset temperature threshold is a preset temperature threshold of the user terminal, and when the current temperature of the user terminal exceeds the preset temperature threshold, channel parameters for reducing the power consumption of the user terminal, for example, the number of data streams for reducing the power consumption, are generated. The predetermined temperature threshold may be 46 ℃.
In one possible implementation, if the current temperature of the user terminal is 47 ℃ and exceeds the preset temperature threshold of 46 ℃, the number of data streams that the user terminal can generate to reduce its own power consumption is 2.
Step 502, a first set of channel parameters is generated from at least one channel parameter.
In one possible implementation manner, if the number of data streams generated by the user terminal to reduce its own power consumption is 2, the first channel parameter generated based on the number of data streams includes 2 data streams. If the number of data streams generated by the user terminal for reducing the self power consumption is 2 and the channel quality indicated value for reducing the self power consumption is 6, the first channel parameter generated based on the number of data streams contains the number of data streams which is 2 and the channel quality indicated value is 6.
In the foregoing embodiments, the preconditions for the user terminal to generate the first set of channel parameters are introduced. In another embodiment of the present application, an embodiment is described how a UE (corresponding to the user terminal 10 of the present application) and a base station (corresponding to the access network device 20 of the present application) interact specifically, thereby reducing the power consumption of the UE. A flowchart of this embodiment may refer to fig. 6, and the specific implementation steps in the flowchart are as follows:
and P1, the UE judges whether the current temperature exceeds a preset temperature threshold.
It should be noted that, one specific implementation manner of power consumption detection is temperature detection, and the greater the power consumption of the UE, the higher the detected current temperature of the UE after the UE performs temperature detection.
If yes, executing the step P2;
if not, go to step P3.
Step P2, the UE generates a Channel State Information (CSI) report, wherein the CSI report comprises a Rank Indication (RI), a Precoding Matrix (PMI) and a Channel Quality Indication (CQI) for reducing the power consumption of the UE.
It should be noted that, the channel state information CSI report herein corresponds to the first channel parameter set in the previous embodiments of the present application. The calculation of the channel quality indication CQI value is related to the rank indication RI, the precoding matrix PMI, the channel state information reference signal resource indication CRI. The calculation of the precoding matrix PMI is related to the rank indication RI and CRI. The precoding matrix PMI is used for indicating the optimal coding matrix of the current DL-SCH channel transmission of the access network device.
If the access network device adopts the rank indication RI and the precoding matrix PMI for reducing power consumption to calculate the channel quality indication CQI, the value of the calculated channel quality indication CQI will be smaller, and when the value of the channel quality indication CQI is smaller, the corresponding level of the modulation coding scheme (for example, the modulation coding strategy value MCS) will be lower. In general, when the channel quality is poor, the level of the modulation coding scheme is low, so that the modulation coding efficiency is low. For example, the bit error rate increases, thereby affecting the channel quality. In order to ensure the Channel quality, when the smaller Channel quality indication CQI is obtained by calculation, the level of the modulation coding mode corresponding to the Channel quality indication CQI is not adopted, but the highest level of the modulation coding mode is adopted, so that the error rate of the DL-SCH (DownLink Shared Channel) is not more than 10%, thereby ensuring the Channel quality.
Step P3, passing a preset time T 0 And then continues to execute P1 again.
And P4, the UE periodically or aperiodically transmits the CSI report to the base station.
And P5, the base station receives the CSI report, adjusts the number of transmitting antennas and receiving antennas of the UE according to the rank indication RI, and determines a modulation coding mode according to the channel quality indication CQI.
Step P6, passing a preset time T 0 And then, the UE judges whether the current temperature exceeds a preset temperature threshold value.
If yes, executing a step P7;
if not, ending.
Step P7, the UE judges whether the UE is in a carrier aggregation state or not;
if yes, executing a step P8;
if not, ending.
It should be noted that, the carrier aggregation in this embodiment corresponds to configuring the primary carrier and the secondary carrier for the ue in the foregoing embodiments of the present application.
And P8, the UE sends a message to the base station, and the base station is instructed to prohibit the UE from using the secondary carrier SCC.
Note that, the secondary carrier SCC here corresponds to the secondary carrier in the foregoing embodiments of the present application. The message here may be a scg-Failure (secondary cell group-Failure, secondary cell group Failure) report. By way of example, the types of SCG-Failure reports may be t 310-expire, t 312-expire, ynchReconfigFailure-SCG, rl-MaxNumRetx, SCG-reconfigFailure, etc.
Step P9, after a preset time T 0 And then, the UE judges whether the current temperature exceeds a preset temperature threshold value.
If yes, executing a step P10;
if not, ending.
In step P10, the UE determines whether the UE satisfies low mobility, or whether the UE is in a cell, or whether the UE has good signal quality.
If yes, go to step P11.
If not, ending.
In step P11, in the time domain, the measurement period for the base station radio resource management RRM is prolonged, or the number of symbols measured in each measurement period is reduced. The number of symbols here is the minimum resource granularity in the time domain. In the frequency domain, detected subcarriers, sync signal blocks SSB (Sync Signal and PBCH block, sync signal blocks), pilot frequency occupation, and the like are reduced. The sub-carriers here are the smallest resource granularity in the frequency domain.

Step Q2, the UE judges whether the current temperature of the UE continues for a preset time T 0 ；
If yes, executing Q4;
if not, then Q3 is performed.
