Description

Search space detection method, terminal and network side device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a search space detection method, a terminal, and a network side device.
Background
In NR (New RAT, new radio access technology) PDCCH (Physical Downlink Control Channel), a terminal configures at most 3 CORESET (Control resource set) and 10 search spaces on an active BWP (BandWidth Part). When configuring the search space, the high-level signaling configures a detection period and a detection offset value thereof, a search space type, a DCI (Downlink Control Information) format to be detected, and the like. And the terminal detects the PDCCH in different search spaces according to the time domain detection position configured by the high-level signaling.
In NR, different search spaces correspond to different search space types and different detection positions. The terminal can only perform PDCCH detection according to the detection position configured by the higher layer signaling, but there may be a case where there is no PDCCH carrying scheduling information of the terminal in a certain search space, but the terminal still needs to detect the search space. In particular, when a terminal is configured with a large number of search spaces, but scheduling for the terminal is small, the terminal needs a large number of PDCCH detections. Since the terminal performs many detections of PDCCHs in different search spaces that do not contain scheduling information of the terminal, energy consumption of the terminal may be wasted.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The embodiment of the invention provides a search space detection method, which is applied to a terminal and comprises the following steps of:
step 101, detecting a wake-up signal corresponding to a target search space before or at each detection time of the target search space.
The terminal first needs to determine a target search space and obtain the detection time of the target search space. And for each detection moment, detecting whether a wake-up signal corresponding to the target search space exists before the detection moment or when the detection moment arrives. Wherein a target search space corresponds to a wake-up signal, if the wake-up signal is detected, step 102 is executed, and if the wake-up signal is not detected, step 103 is executed.
And 102, when the wake-up signal is detected, detecting a Physical Downlink Control Channel (PDCCH) in the target search space.
When the terminal is before the detection time of the target search space or at the detection time of the target search space, if the wake-up signal is detected, the PDCCH detection may be performed on the target search space. By using the detected wake-up signal as a basis for PDCCH detection of the target search space, the detection times of the search space and the power consumption of the terminal can be reduced.
And 103, when the wake-up signal is not detected, giving up the PDCCH detection on the target search space.
When the terminal is before the detection time of the target search space or at the detection time of the target search space, if the wake-up signal is not detected, the PDCCH detection is abandoned for the target search space, so that the blind detection can be avoided.
The embodiment of the invention detects the wake-up signal corresponding to the target search space before or at each detection time of the target search space, and executes the process of detecting the PDCCH of the target search space after the wake-up signal is detected, so that the detection of the search space can not be carried out under the condition of no terminal scheduling, the detection times of the search space and the power consumption of the terminal are reduced, and the energy conservation of the terminal is ensured.
In an embodiment of the present invention, the method further includes: and receiving configuration information of a corresponding wake-up signal configured for the target search space by the network side equipment.
The terminal can also receive configuration information of a corresponding wake-up signal configured for the target search space, which is set and sent by the network side, and the network side equipment can generate the configuration information of the wake-up signal when configuring the wake-up signal and send the configuration information to the terminal.
The method comprises the steps of receiving configuration information sent by network side equipment, and detecting an awakening signal corresponding to a target search space before or at each detection time of the target search space.
After the terminal receives the configuration information of the wake-up signal sent by the network side device, the process of detecting the wake-up signal corresponding to the target search space may be executed before the detection time of the target search space or at the detection time of the target search space. The detection instant referred to herein means each detection instant for the target search space.
That is, at this time, only after the terminal receives the configuration information of the wake-up signal, the wake-up signal corresponding to the target search space may be detected before the detection time of the target search space or at the detection time of the target search space, and the PDCCH detection process for the target search space is executed in a state where the wake-up signal is detected. The configuration information of the wake-up signal received by the terminal is used as the basis for detecting the wake-up signal, so that the optimization of the detection process can be realized, and the implementation of the detection process is ensured.
In this embodiment of the present invention, a scheme for receiving configuration information of a corresponding wake-up signal configured for a target search space by a network side device further includes: and when receiving the configuration information sent by the network side equipment, determining whether the wake-up signal corresponding to the target search space is in an activated or enabled state according to the configuration information.
When the terminal receives the configuration information of the corresponding wake-up signal configured for the target search space, which is sent by the network side device, the state of the wake-up signal configured by the network side device can be determined according to the received configuration information. The state of the wake-up signal includes an activated or enabled state, and may further include a deactivated or disabled state. The activation state and the enable state are expressed in the same sense, but expressed in different ways, and the corresponding deactivation state and disable state are expressed in the same sense.
When the terminal determines the state of the wake-up signal according to the configuration information, it is actually determined whether the wake-up signal is in an activated or enabled state or in a deactivated or disabled state. Different operations may be performed for different states of the wake-up signal.
The following describes in detail the process in which the terminal determines the state of the wake-up signal according to the configuration information and performs different operations for different states of the wake-up signal.
The method for determining whether the wake-up signal corresponding to the target search space is in an activated or enabled state comprises the following steps: if the configuration information carries the first indication field, determining that an awakening signal corresponding to the target search space is in an activated or enabled state; and detecting the wake-up signal corresponding to the target search space before or at each detection time of the target search space when the wake-up signal is in an activated or enabled state.
After receiving the configuration information of the wake-up signal sent by the network side device, the terminal may detect an indication field carried in the configuration information, and if the configuration information carries the first indication field, may determine that the wake-up signal configured for the target search space by the network side device is in an activated or enabled state. When it is determined that the wake-up signal is in the activated or enabled state, the terminal may execute a process of detecting the wake-up signal before or at each detection time of the target search space according to the acquired activated or enabled state of the wake-up signal.
Determining whether the wake-up signal corresponding to the target search space is in an activated or enabled state according to the configuration information, further comprising: if the configuration information carries the second indication field, determining that the awakening signal corresponding to the target search space is in a deactivated or de-enabled state; and detecting the PDCCH of the target search space at each detection moment of the target search space when the wake-up signal is in a deactivated or de-enabled state.
After receiving the configuration information of the wake-up signal sent by the network side device, the terminal may detect an indication field carried in the configuration information, and if the configuration information carries a second indication field, may determine that the wake-up signal configured for the target search space by the network side device is in a deactivated or disabled state. When determining that the wake-up signal is in the deactivation or disable state, the terminal may directly perform a PDCCH detection process on the target search space at each detection time of the target search space according to the acquired deactivation or disable state of the wake-up signal.
The configuration information is received, the wake-up signal is detected according to the activation or enabling state of the wake-up signal carried by the configuration information, the PDCCH detection on the target search space is executed after the wake-up signal is detected, the PDCCH detection is directly carried out on the target search space according to the deactivation or disabling state of the wake-up signal carried by the configuration information, and different operation flows can be determined according to different states of the wake-up signal carried by the configuration information.
In the embodiment of the invention, the configuration information carries the relation between the detection time of the wake-up signal and the detection time of the target search space; the detection time of the wake-up signal is positioned before the detection time of the target search space; or the detection time of the wake-up signal is the same as the detection time of the target search space.
The configuration information of the wake-up signal sent by the network side device carries the relationship between the detection time of the wake-up signal and the detection time of the target search space, and the terminal acquires the relationship between the detection time of the wake-up signal and the detection time of the target search space after receiving the configuration information. The detection of the wake-up signal can be performed at an appropriate time depending on the relationship between the two.
The detection moment of the wake-up signal is positioned before the detection moment of the target search space; or the detection time of the wake-up signal is the same as the detection time of the target search space. For the condition that the detection time of the wake-up signal is before the detection time of the target search space, the network side device may advance by a time length on the basis of the detection time of the target search space, and determine the time length as the detection time of the wake-up signal.
In the embodiment of the present invention, the association relationship between the wake-up signal and the search space may be as follows:
each detection slot of the search space corresponds to one or more wake-up signals. Specifically, one search space in one detection timeslot is associated with one wake-up signal, and if there are multiple search spaces, the multiple search spaces correspond to multiple wake-up signals, and the multiple wake-up signals may be time division multiplexed, frequency division multiplexed, or code division multiplexed.
For example: if the current search space corresponds to 3 search spaces, the wake-up signal corresponding to each search space is activated. Wherein, the detection period of the search space 1 is 5 slots, the deviant is 1slot, corresponding to the wake-up signal 1; the detection period of the search space 2 is 2 slots, the deviant is 0slot, and the detection period corresponds to the wake-up signal 2; the period of the search space 3 is 4 slots and the offset value is 0 slots, corresponding to the wake-up signal 3. The wake-up signals 1, 2 and 3 can be time division multiplexed, frequency division multiplexed or code division multiplexed. The time slot in which the network side device sends the wake-up signal may be the same as or different from the detection time slot of the search space. If the two are different, the time slot of the network side equipment for sending the wake-up signal is before the detection time slot of the search space. The wake-up signal to be transmitted corresponding to each time slot in which the search space needs to be detected is shown in table 1.
Figure BDA0001828677750000101
TABLE 1
In the situation shown in table 1, it is described by taking an example that the time slot for the network side device to send the wake-up signal is the same as the detection time slot of the search space. For time slot 0, the network side equipment sends a wake-up signal 2, and when the terminal detects the wake-up signal 2, the terminal performs PDCCH detection on the search space 2; for a time slot 4, the network side equipment sends wake-up signals 2 and 3, when the terminal detects the wake-up signal 2, the terminal performs PDCCH detection on the search space 2, and when the terminal detects the wake-up signal 3, the terminal performs PDCCH detection on the search space 3; for time slot 6, the network side equipment sends a wake-up signal 1, and when the terminal detects the wake-up signal 1, the terminal performs PDCCH detection on the search space 1; for the time slot 8, the network side device sends the wake-up signal 3, and when detecting the wake-up signal 3, the terminal performs PDCCH detection on the search space 3.
In the embodiment of the invention, the configuration information carries the period of the wake-up signal; and the terminal detects the wake-up signal in a wake-up signal period, and then performs PDCCH detection on the target search space at each detection moment of the target search space.
The configuration information sent by the network side device also carries a wake-up signal period, and after the terminal acquires the wake-up signal period, if the terminal detects a wake-up signal in one wake-up signal period, the terminal needs to perform PDCCH detection on the target search space at each detection time.
Namely, the association relationship between the wake-up signal and the search space can also be as follows: the network side device configures the time domain granularity (wake-up signal period) of the wake-up signal through a high-level signaling, including the time domain period and the offset value, or only configures the time domain period, and the offset value is used as a selectable item. One search space is associated with one wake-up signal, and a plurality of search spaces may exist in one time domain period, which needs to correspond to a plurality of wake-up signals. The plurality of wake-up signals may be time division multiplexed, frequency division multiplexed, or code division multiplexed. The time slot in which the network side device sends the wake-up signal may be the same as or different from the detection time slot of the search space.
For example: if the current search space corresponds to 3 search spaces, the wake-up signal corresponding to each search space is activated. The time domain period of the wake-up signal configured by the high layer signaling is 4 slots, and the offset value is 0slot. The detection period of the search space 1 is 5 slots, and the deviant is 1slot, corresponding to the wake-up signal 1; the detection period of the search space 2 is 2 slots, the deviant is 0slot, and the detection period corresponds to the wake-up signal 2; the detection period of the search space 3 is 4 slots and the offset value is 0 slots, corresponding to the wake-up signal 3. Wherein, the wake-up signals 1, 2 and 3 can be time division multiplexing, frequency division multiplexing or code division multiplexing. The time slot in which the network side device sends the wake-up signal may be the same as or different from the detection time slot of the search space. If the two are different, the time slot of the network side equipment for sending the wake-up signal is before the detection time slot of the search space. Specifically, a few time slots ahead of time need to be configured by the network side device.
Then, in every 4 timeslots, the wake-up signal to be transmitted is shown in table 2:
Figure BDA0001828677750000111
TABLE 2
In the situation shown in table 2, the network side device sends the wake-up signal once in one wake-up signal period, and for the first wake-up signal period (time slot 0 to time slot 3), the network side device sends the wake-up signal once, and only sends the wake-up signal 2 in the sending process, so that the terminal can perform PDCCH detection on the search space 2 in time slot 0 and time slot 2 when detecting the wake-up signal 2. For the second wake-up signal period (time slot 4 to time slot 7), the network side device sends a wake-up signal once, and sends the wake-up signals 1, 2, and 3 in the sending process, so that the terminal can perform PDCCH detection on the search space 1 in the time slot 6 when detecting the wake-up signal 1, perform PDCCH detection on the search space 2 in the time slots 4 and 6 when detecting the wake-up signal 2, and perform PDCCH detection on the search space 3 in the time slot 4 when detecting the wake-up signal 3.
In the embodiment of the invention, the wake-up signal corresponding to the target search space is detected before each detection time of the target search space or at each detection time of the target search space, and the process of performing PDCCH detection on the target search space is executed after the wake-up signal is detected, so that the detection of the search space can be performed without scheduling of a terminal, and the PDCCH detection is executed after the wake-up signal is detected, thereby realizing reduction of the detection times of the search space and the power consumption of the terminal, and ensuring the energy conservation of the terminal.
An embodiment of the present invention provides a search space detection method, which is applied to a network side device, and as shown in fig. 2, the method includes:
