Detailed Description
Currently, the network side indicates to the UE whether to wake up to monitor PDCCH in the active period of the adjacent DRX cycle by corresponding indication information before the active period of each DRX cycle. When the UE does not need to wake up to monitor the PDCCH, the UE determines the sleep state according to the length of the adjacent DRX period.
For example, when the length of the adjacent DRX cycle is 40ms, the UE may enter the corresponding sleep state with 40ms as the sleep duration. But before the active period of the next DRX cycle, the UE still needs to wake up to detect the indication information sent by the network side to determine whether the active period of the next DRX cycle is to wake up for monitoring. Therefore, the UE cannot flexibly enter different sleep states, and the power consumption of the UE is high finally.
In order to solve the problem, the invention provides a control method of a user terminal, which is applied to the method, when the user terminal does not need to wake up to monitor the PDCCH in a corresponding activation period, the energy-saving signal indication information also comprises second indication information used for indicating the moment when the user terminal detects the energy-saving signal indication information next time, so that the user terminal can enter a corresponding sleep state based on the second indication information when the user terminal does not need to wake up to monitor the PDCCH in the corresponding activation period, and does not need to wake up to detect the energy-saving signal indication information before each DRX period, and the user terminal can more flexibly determine which sleep state to enter, thereby increasing the sleep duration of the user terminal to the maximum extent and reducing the power consumption of the user terminal.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling a user terminal, where the method may include the following steps:
and 11, detecting the energy-saving signal indication information in the current detection window.
Wherein: the power saving signal indication information may include: and first indication information, which is used for indicating whether the UE needs to wake up to monitor the PDCCH in a corresponding activation period.
When the UE does not need to wake up to monitor the PDCCH in a corresponding active period, the energy saving signal indication information may further include: and second indication information, configured to indicate a time when the UE detects the energy saving signal indication information next time.
In a specific implementation, the detection window may be periodic. The network side may configure the period of the detection window through Radio Resource Control (RRC) signaling, or may indicate the period of the detection window by a higher layer parameter.
In specific implementation, the length of each detection window can be set by those skilled in the art according to actual needs, and is not limited in particular. For example, the length of the detection window may be set based on the time required to detect the power saving signal indication information, the operation to be performed within the detection window, and other factors.
In a specific implementation, the detection window has a corresponding relationship with the activation period. Within the detection window, first indication information indicating whether the UE needs to wake up to monitor the PDCCH in a corresponding active period may be detected.
In an embodiment of the present invention, in order to reduce the time delay and improve the accuracy of control, the detection windows may be set to be close to and in one-to-one correspondence with the corresponding activation periods. The detection window is adjacent to the corresponding activation period, that is, the end time of the detection window is used as the start time of the corresponding activation period, so that the PDCCH is monitored more accurately in the activation period by using the result of the corresponding operation executed in the detection window. The detection windows are in one-to-one correspondence with the corresponding activation periods, that is, in one detection window, only first indication information indicating whether the UE needs to wake up to monitor the PDCCH in one activation period can be acquired, so that the time delay of the first indication information is reduced.
In other embodiments of the present invention, a certain gap may also exist between the detection window and the corresponding activation period, and the detection window may correspond to two or more activation periods, and may be specifically set according to actual needs.
In a specific implementation, whether the UE needs to wake up to monitor the PDCCH in a corresponding active period may be indicated in a preset bit of the first indication information. For example, it may be indicated in the 2 nd bit of the first indication information whether the UE needs to wake up to monitor the PDCCH in the corresponding active period. Specifically, when the value of the bit is 1, it indicates that the UE needs to wake up to monitor the PDCCH in the corresponding active period, and when the value of the bit is 0, it indicates that the UE does not need to wake up to monitor the PDCCH in the corresponding active period.
In a specific implementation, the second indication information may be set by using multiple methods, that is, the UE is indicated by using multiple methods to detect the power saving signal indication information next time. For example, the second indication information may directly indicate a specific time value of the time when the UE detects the energy saving signal indication information next time, and may indicate an interval duration between the time when the UE detects the energy saving signal indication information next time and a current detection window.
In an embodiment of the present invention, in order to save signaling resources, an interval duration between a next time when the UE detects the energy saving signal indication information and a current detection window may be a preset number of detection window periods. The specific numerical value of the preset number can be set according to the period of the detection window and the interval duration.
And step 12, when the first indication information indicates that the user terminal does not need to wake up to monitor the PDCCH in a corresponding activation period, obtaining an interval duration between the next time when the user terminal detects the energy-saving signal indication information and a current detection window based on the second indication information, wherein the interval duration is used as a first sleep duration, and the user terminal enters a corresponding sleep state based on the first sleep duration.
Step 12 is described in detail below with reference to fig. 2:
referring to fig. 2, each detection window is immediately adjacent to an active period. And first indication information detected in each detection window is used for indicating whether the UE needs to wake up to monitor the PDCCH in an adjacent activation region. Specifically, the detection window w1 is immediately adjacent to the activation period Q1, the detection window w2 is immediately adjacent to the activation period Q2, and the detection window w3 is immediately adjacent to the activation period Q3.
Taking the interval duration between the time when the UE next detects the energy saving signal indication information and the current detection window in the second indication information as M detection window periods as an example, assuming that the length of the detection window period is Kms, where M and K are positive integers, when the current detection window is a detection window w2, if the first indication information indicates that the UE does not need to wake up for PDCCH monitoring and M indicated in the second indication information is 3, the detection window when the UE next detects the energy saving signal indication information is a detection window w 3. At this time, the interval duration between the detection window w2 and the detection window w3 is (K × 3) ms, that is, the first sleep duration is (K × 3) ms. After determining the first sleep duration, the UE may enter the corresponding sleep state until the next detection window w3 comes.
Fig. 3 is another control method for a ue according to an embodiment of the present invention, where the method includes the following steps:
and step 31, detecting the energy-saving signal indication information in the current detection window.
Wherein: the power saving signal indication information includes: first indication information, configured to indicate whether the ue needs to wake up to monitor a PDCCH in a corresponding active period; when the ue does not need to wake up to monitor the PDCCH in the corresponding active period, the energy-saving signal indication information further includes: and the second indication information is used for indicating the time when the user terminal detects the energy-saving signal indication information next time.
In a specific implementation, step 31 may be implemented with reference to the description about step 11, which is not described herein again.
And step 32, determining whether the ue needs to wake up to monitor the PDCCH in the corresponding active period based on the first indication information.
Step 33 is performed when the UE does not need to wake up to monitor the PDCCH in the corresponding active period, otherwise step 35 is performed.
And step 33, obtaining an interval duration between the next time when the user terminal detects the energy-saving signal indication information and the current detection window based on the second indication information, wherein the interval duration is used as a first sleep duration, and the user terminal enters a corresponding sleep state based on the first sleep duration.
In a specific implementation, step 33 may be implemented with reference to the above description about step 12, which is not described herein again.
And step 34, monitoring the PDCCH in the corresponding activation period.
Monitoring the PDCCH during a corresponding activation period when the first indication information indicates that the user terminal needs to wake up to detect the PDCCH during the corresponding activation period.
In an implementation, before monitoring the PDCCH, the UE usually needs to wake up again to complete time frequency synchronization and Radio Resource Management (RRM) operations. In the embodiment of the invention, in order to further reduce the power consumption of the UE, the UE can complete at least one of time-frequency synchronization and wireless resource management in the current detection window, so that the awakening times of the UE are reduced, and the power consumption of the UE is reduced.
Preferably, the UE may further perform two operations, i.e., time-frequency synchronization and radio resource management, within the current detection window, so as to reduce power consumption of the UE to the maximum extent.
Step 35, determining the time for detecting the energy saving signal indication information next time based on the monitoring result of the PDCCH, obtaining an interval duration for adjacently detecting the energy saving signal indication information based on the determined time, wherein the interval duration is used as a second sleep duration, and the user terminal enters a corresponding sleep state based on the second sleep duration.
In a specific implementation, the UE may schedule the PDCCH multiple times during the active period. The UE may determine a next time to detect the power saving signal indication information time based on the last scheduled PDCCH. In other words, the network side may indicate the next time of detecting the energy saving signal indication information in the last PDCCH sent to the UE.
The PDCCH sent to the UE at the last time is closest to the time for detecting the energy-saving signal indication information at the next time in time, so that the time closest to the time for detecting the energy-saving signal indication information at the next time can be more accurately determined, and the detection accuracy is improved.
In specific implementation, the time for detecting the energy saving signal indication information next time may be indicated on a preset bit of a PDCCH last scheduled by the UE, and a specific indication method is not limited. For example, a specific time value of the time when the UE detects the energy saving signal indication information next time may be directly indicated on a preset bit of the last scheduled PDCCH, and an interval duration between the time when the UE detects the energy saving signal indication information next time and the current detection window may be indicated.
In an embodiment of the present invention, in order to save signaling resources, an interval duration between a next time when the UE detects the energy saving signal indication information and a current detection window may be a preset number of detection window periods. The specific numerical value of the preset number can be set according to the period of the detection window and the interval duration.
Step 35 is described in detail below with reference to fig. 2:
when the current detection window is the detection window w1, if the first indication information indicates that the UE needs to wake up for PDCCH monitoring, the UE wakes up for PDCCH monitoring in the active period Q1. Meanwhile, the UE last scheduled PDCCH based on the activation period Q1 (as in the figure)
Figure BDA0001852353740000091
Shown), it is determined that the interval duration between the time when the UE detects the energy saving signal indication information next time and the current detection window is 2 detection window periods, that is, M is 2, then the detection window when the UE detects the energy saving signal indication information next time is the detection window w 2.
The interval duration between the detection window w1 and the detection window w2 is (K × 2) ms, i.e., the second sleep duration is (K × 2) ms. After determining the second sleep duration, the UE may enter a corresponding sleep state based on the second sleep duration. For example, deep sleep, light sleep, and light sleep can be entered, and what kind of sleep state to enter can be determined by the second sleep duration.
It can be known from the above that, by using the control method of the ue in the embodiment of the present invention, the interval duration between the adjacent times for detecting the energy saving signal indication information is used as the first sleep duration, and the ue does not need to wake up to detect the energy saving signal indication information before each DRX cycle, so that the ue can more flexibly determine which sleep state to enter, increase the sleep duration of the ue to the maximum extent, and reduce the power consumption of the ue.
