To facilitate understanding, some contents involved in the embodiments of this application are described below:

1. Low power consumption receiver.

The low-power receiver can be called a low-power wake up radio (LP-WUR). The basic working principle of LP-WUR is that the receiving end contains a first module and a second module. The first module is the main communication module and is used for sending and receiving mobile communication data. The second module is a low-power receiving module (which can also be called Low-power wake-up receiving module), used to receive wake-up signal (WUS). In the energy-saving state, the terminal turns on the low-power receiving module to monitor the low-power wake-up signal (LP-WUS) and turns off the main communication module. When downlink data arrives, the network side device will send a wake-up signal to the terminal. The terminal monitors the wake-up signal through the low-power receiving module and then triggers the main communication module from off to on through a series of judgments. At this time, the low-power consumption The receiving module enters the closed state from the working state. The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive low-power wake-up signals when turned on.

2. Low-power wake-up signal

In order to reduce the receiving activity of the terminal in the standby state, so that the radio frequency (RF) and baseband modules are truly turned off, thereby greatly reducing the power consumption of communication reception, a near "zero" power can be introduced in the receiving module of the terminal. The receiver is thus implemented. This nearly "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem (MODEM) signal processing, and only relies on passive matched filtering and smaller power consumption signals. deal with.

On the base station side, by triggering the wake-up signal on-demand, a near-zero power receiver can be activated to obtain the activation notification, thereby triggering a series of processes within the terminal, such as turning on radio frequency transceiver and baseband processing, etc. module.

This kind of wake-up signal is usually a relatively simple on-off keying signal, so that the receiver can obtain the wake-up notification through simple energy detection, and subsequent possible sequence detection and recognition processes. In addition, while the terminal turns on the low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain working at a lower power consumption level, thereby achieving power consumption savings by receiving the wake-up signal.

The interception processing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios.

Referring to Figure 2, an embodiment of the present application provides an interception processing method. As shown in Figure 2, the interception processing method includes:

Step 201: The terminal monitors the first information;

Optionally, in one embodiment, the terminal monitors the first information within the skipped PDCCH monitoring time period or outside the activation time.

Step 202: The terminal determines first indication information according to the first information;

Wherein, the first indication information is used to indicate at least one of the following:

Whether to start the first time window;

The length of the first time window;

The number of retransmissions of the first transmission;

Whether to perform Hybrid Automatic Repeat Request (HARQ) feedback for the first transmission;

Whether to postpone the retransmission of the first transmission until the time period when PDCCH monitoring of the physical downlink control channel is resumed;

whether the first transmission was successfully received;

Wherein, the first time window is used for the terminal to monitor the first PDCCH.

In this embodiment of the present application, the above-mentioned first information may include the above-mentioned first instruction information, or the first information may have a corresponding association relationship with the first instruction information.

Optionally, when the first indication information indicates to start the first time window, the terminal needs to start or resume monitoring of the first PDCCH within the first time window. That is to say, whether to start the first time window is equivalent to : Whether to perform, start or resume the first PDCCH monitoring of the first time window length. Wherein, activating the first time window can be understood as resuming PDCCH monitoring of the length of the first time window, and not activating the first time window can be understood as pausing, stopping or skipping the first PDCCH monitoring within the first time window.

Optionally, in some embodiments, the above-mentioned first time window can be understood as a retransmission time window, and the above-mentioned first PDCCH includes but is not limited to retransmission PDCCH. That is, activating or not activating the first time window can be understood as activating or not activating the retransmission time window. When the retransmission time window is activated, the terminal performs retransmission of the first PDCCH including the PDCCH within the retransmission time window. of monitoring. In this embodiment, the first information is used to determine whether to start the first time window, so that the monitoring situation of the PDCCH can be dynamically adjusted to reduce unnecessary PDCCH monitoring power consumption, and at the same time, the transmission time caused by the PDCCH skipping mechanism can be reduced. extension.

Optionally, the terminal can trigger whether to start or stop the first time window based on some predefined rules or conditions. For example, if the terminal sends uplink control information (UCI) of a specific priority, the first time window is started; in addition, the network side device can also set an implicit or explicit instruction to start or not start the first time window. window. In one embodiment, the length of the first time window is determined through the first information, so that the monitoring and monitoring duration of the PDCCH can be dynamically adjusted according to actual conditions.

Optionally, the length of the first time window may also be configured by a protocol agreement or a network side device. For example, the network side device configures the length of the first time window to be length 0. For another example, the lengths of the first time window of network-side device configuration candidates are length 1, length 2, and length 3. The length of the first time window is then indicated through the first indication information.

Optionally, the first indication information indicates the number of retransmissions of the first transmission. In this embodiment, more flexible retransmissions can be achieved by dynamically indicating the number of retransmissions of the first transmission, thereby avoiding unnecessary terminal power consumption caused by excessive retransmissions. Optionally, the above-mentioned number of retransmissions may be the maximum or minimum number of retransmissions of the first transmission.

In one embodiment, the first transmission needs to be completed while meeting a packet delay budget (PDB). The network side device may determine whether it is necessary to reduce the amount of data based on at least one of the current remaining data transmission delay, importance, priority, inter-packet correlation and quality of service (QoS) level of the first transmission. Or increase the number of retransmissions. The remaining data transmission delay here refers to: PDB minus the time that has been consumed before scheduling the data transmission (the time that has been consumed before scheduling the data transmission, can be: from the time when the data arrives at the RAN side to when the data starts to be scheduled) time interval between transmissions). For example, if the current remaining data transmission delay of the first transmission cannot satisfy the retransmission process twice, the network side device can dynamically instruct the terminal that the maximum number of retransmissions of the first transmission is 1. In another embodiment, if the first transmission is a data transmission with a high importance level, the network side device may dynamically instruct the terminal to increase the maximum number of retransmissions of the first transmission. In another embodiment, the network side device determines the maximum number of retransmissions of the first transmission by combining two factors: the remaining data transmission delay for the first transmission and the QoS level of the first transmission.

Optionally, the first indication information indicates whether to perform HARQ feedback for the first transmission. When it is determined that the HARQ feedback of the first transmission is not to be performed, the network side device can default the HARQ feedback of the first transmission to a positive acknowledgment (ACK) or a negative acknowledgment (NACK), thereby reducing the overhead of feedback resources and the overhead caused by the feedback. unnecessary waste of terminal power consumption. Further, when the default is ACK, the first transmission sent by the network by default will be successfully received by the terminal. After receiving the first transmission, the terminal does not need to perform HARQ feedback or subsequent retransmission processes, thereby avoiding unnecessary terminal power consumption such as HARQ feedback and retransmission.

It should be noted that there is no further limitation here as to the circumstances under which the network side device instructs the terminal not to perform HARQ feedback of the first transmission. For example, one possible embodiment is that the network side device determines whether the HARQ feedback of the first transmission will fall into the skipped PDCCH listening period, the importance, priority, inter-packet correlation and remaining transmission delay of the first transmission. Wait for at least one factor to determine whether to allow the terminal to perform HARQ feedback for the first transmission.

In one embodiment, the terminal receives an instruction to skip PDCCH monitoring sent by the network side device, and performs skipping PDCCH monitoring according to the instruction. However, during the period of skipping PDCCH monitoring, there are still some transmissions that have not completed the corresponding HARQ feedback. In order to prevent the terminal from consuming power by sending HARQ feedback during the period of skipping PDCCH monitoring, the network side device can instruct to cancel the corresponding HARQ feedback of these transmissions. HARQ feedback to achieve terminal energy saving.

It should be noted that the first indication information may be carried through downlink control information (Downlink Control Information, DCI). If the first indication information indicates performing HARQ feedback of the first transmission, the terminal performs HARQ feedback of the first transmission according to the corresponding feedback time indication in the DCI. Optionally, if the first indication information indicates not to perform HARQ feedback of the first transmission, the terminal ignores the corresponding feedback time indication in the DCI and does not perform HARQ feedback; further, because the network side device passes the third transmission in the DCI An indication information indicates that HARQ feedback is not performed. Therefore, the network side device processes the HARQ feedback of the first transmission as ACK or NACK.

Optionally, in the case where the first indication information indicates whether to postpone the retransmission of the first transmission to the time period for resuming PDCCH monitoring, if it is determined that the retransmission of the first transmission is postponed to the time period for resuming PDCCH monitoring, then before jumping After the PDCCH monitoring time period, the terminal does not need to resume PDCCH monitoring in order to monitor retransmissions, thereby reducing PDCCH monitoring power consumption. For example, in one embodiment, the terminal receives an instruction to skip PDCCH monitoring sent by the network side device, and performs skip PDCCH monitoring according to the instruction. However, during the period of skipping PDCCH monitoring, there are still some transmissions that have not completed the corresponding retransmission process. In order to avoid the terminal having to resume monitoring the PDCCH due to monitoring retransmissions and consuming power during the period of skipping PDCCH monitoring, network side equipment The retransmission of these transmissions can be instructed to be postponed until the time period when monitoring of the physical downlink control channel PDCCH is resumed, thereby achieving terminal energy saving.

It should be understood that postponing the retransmission of the first transmission to the time period for resuming PDCCH monitoring can be understood as: postponing the retransmission of the first transmission to the next PDCCH monitoring time period of the terminal. The next PDCCH monitoring time period may be: skipping the time period after the end of the PDCCH monitoring duration, or the next discontinuous reception (DiscontinuousReception, DRX) duration (onduration); or it may be the next DRX deactivation During the operation of the timer (inactivitytimer), there is no limit here. In addition, it should be noted that postponing the retransmission of the first transmission can be understood as postponing starting the retransmission timer of the first transmission. For example, after the terminal feeds back the first transmitted NACK to the network-side device, if it is skipping the PDCCH listening period or the DRX OFF period (that is, the time period outside the activation time), it will be assumed that the network-side device will Retransmission scheduling is performed after PDCCH monitoring is resumed, rather than immediately enabling or resuming PDCCH monitoring for this NACK feedback.

Optionally, whether the first transmission is successfully received refers to whether the first transmission is successfully received by the network side device. That is to say, the network side device instructs the terminal to provide HARQ feedback for the first transmission through the first indication information. If the first transmission is successfully received, the terminal does not need to monitor the retransmission process of the first transmission. If the first transmission is not successfully received, then the terminal only needs to monitor the first transmission at this time. retransmission process. It should be noted that, in one embodiment, the first transmission is uplink transmission, that is, data transmission sent by the terminal. In this way, the PDCCH monitoring situation can be dynamically adjusted to reduce unnecessary PDCCH monitoring power consumption caused by retransmissions, and at the same time, the transmission delay caused by the PDCCH skip mechanism can be reduced.

Further, when the first indication information indicates that the first transmission has not been successfully received, the terminal starts a retransmission time window corresponding to the first transmission (i.e., the first time window); in the first If the indication information indicates that the first transmission is successfully received, the terminal does not start the retransmission time window corresponding to the first transmission or stops the operation of the retransmission time window corresponding to the first transmission. It should be understood that the first transmission may be a retransmission or an initial transmission.

Optionally, the content indicated by the above-mentioned first indication information can be realized through display or implicit indication of the first information. For example, the first information is a wake-up signal. The first indication information indicates whether to open the first time window, and the network may implement the indication by sending or not sending a wake-up signal. For example, if the terminal receives the wake-up signal, it means that the first time window is opened; if the terminal does not receive the wake-up signal, it means that the first time window is not opened.

In this embodiment of the present application, the first information is monitored through the terminal, and the first indication information is determined based on the first information. In this way, PDCCH monitoring, HARQ feedback, retransmission, etc. can be dynamically adjusted according to actual needs to avoid unnecessary terminal power consumption. At the same time, it can also avoid the transmission delay caused by excessive skipping of PDCCH monitoring and improve communication performance.

In one embodiment, the behavior of the terminal may not depend on whether the initial transmission is received successfully. The network side device can indicate "start" or "not start" the first time window through DCI or LP-WUS.

Further, the network side device may instruct the terminal whether to start the first time window according to whether the initial transmission is successful.

Optionally, in some embodiments, whether to start the first time window includes: whether to start the first time window within the skipped PDCCH listening period or outside the activation time. That is to say, the first time window will only be activated or not activated within the skipped PDCCH listening time period or outside the activation time.

It should be noted that outside the activation time refers to the time period when the terminal does not monitor the PDCCH, including the time period when the DRX timer is not running.

Optionally, in some embodiments, the first information includes the first indication information, and the first information is carried by at least one of the following: first DCI, Medium Access Control Control Unit (Medium Access Control Control Unit) Element, MAC CE) and Radio Resource Control (Radio Resource Control, RRC) signaling.

Optionally, the first DCI may be a specific type of DCI. For example, DCI format 1-1 or 0-1. For another example, the first DCI is the DCI carried by the PDCCH corresponding to the Type 3 search space.

Optionally, the first information is first indication information.

For example, in some embodiments, the first information includes first indication information. The first indication information includes: whether to start the first time window and the length of the first time window; wherein the length of the first time window is configured by RRC signaling, and whether to start the first time window is indicated by DCI. That is to say, the first indication information (which can also be understood as first information) can be carried by at least one of RRC signaling, MAC CE and DCI.

Optionally, when the first information is carried through the first DCI, the first DCI also carries PDCCH monitoring related indication information. That is to say, in addition to carrying the first information, the DCI also carries PDCCH monitoring related indication information.

Optionally, the first information includes the first indication information, and the first information further includes PDCCH monitoring related indication information. At this time, the terminal determines the first indication information based on the first information, including: the terminal determines the first indication information based on the first indication information contained in the first information and the PDCCH monitoring related indication information. Instructions.

In one embodiment, the terminal determines the indication content of the first indication information and/or whether the first indication information is valid based on the first indication information and the PDCCH monitoring related indication information contained in the first information. .

Optionally, in some embodiments, when the PDCCH monitoring related indication information indicates monitoring or not monitoring the PDCCH, the first indication information takes effect.

Optionally, the PDCCH monitoring related indication information may include at least one of the following: search space group switching indication, PDCCH skipping indication (PDCCH skipping indication), minimum scheduling offset indication (minimum scheduling offset indication), bandwidth part (Bandwidth Part, BWP) ) handover indication, secondary cell dormancy indication (Scelldormancy indication) and wake up indication (wake up indication).

It can be understood that whether the first instruction information is effective refers to whether the terminal executes the first instruction information. For example, when the PDCCH monitoring related indication information indicates not to monitor the PDCCH, the first indication information takes effect. At this time, the terminal needs to read and execute the instruction content of the first instruction information. For another example, in the case where the PDCCH monitoring related indication information indicates monitoring of the PDCCH, the first indication information does not take effect. At this time, the terminal does not execute or ignores the instruction content of the first instruction information.

In the embodiment of the present application, the above-mentioned not monitoring the PDCCH can be understood as skipping the PDCCH monitoring.

In one embodiment, the above-mentioned first indication information can be understood as being bundled with the PDCCH skipping indication for indication. For example, in the case where the PDCCH skipping indication indicates skipping the PDCCH, it is necessary to determine whether to start the retransmission time window during the skipping of the PDCCH according to the first indication information. If the PDCCH skippingindication does not indicate skipping the PDCCH, the first indication information is ignored by default.

In this embodiment of the present application, the above wake-up signal may be detected and received by a first receiver (referring to a main receiver different from the NR signal or channel).

Optionally, the wake-up signal described in the embodiment of this application is the above-mentioned low-power wake-up signal.

Optionally, in some embodiments, when the wake-up signal is received, it corresponds to a situation of the first indication information, for example, the first transmission is not successfully received; when the wake-up signal is not received, it corresponds to the first indication information. An indication of another condition of the message, such as that the first transmission was successfully received.

Optionally, in some embodiments, when a wake-up signal is received, it corresponds to a situation of the first indication information, such as opening the first time window; optionally, when a wake-up signal is not received, Another situation corresponding to the first indication information is, for example, not opening the first time window.

In some embodiments, different sequences of wake-up signals correspond to different situations of the first indication information. For example, wake-up signal sequence 1 indicates starting the first time window. Further, wake-up signal sequence 2 indicates that the first time window is not started. Of course, the network can also indicate not to start the first time window by not sending a wake-up signal.

Optionally, in some embodiments, the first information is a wake-up signal, and the terminal monitoring the first information includes:

The terminal monitors the first information within the skipped PDCCH monitoring time period or outside the activation time.

Further, when the first information is a wake-up signal, the terminal does not need to monitor the first information during the PDCCH monitoring period.

Example 2:

In some embodiments, the above-mentioned first indication information is determined based on the wake-up signal.

In the embodiment of this application, the network side device configures terminal wake-up signal monitoring configuration information, including at least one of the following:

It can be understood that the skipped PDCCH monitoring time period refers to the time period in which the terminal does not actually monitor the PDCCH.

In this embodiment, the first indication information indicates whether to start or not to start the first time window.

For example, during the skipped PDCCH listening time period or outside the activation time, if the terminal detects the wake-up signal, it starts the first time window. It can be understood as: when the terminal detects the wake-up signal, it resumes PDCCH monitoring for the length of the first time window; optional Therefore, within the skipped PDCCH listening time period or outside the activation time, if the terminal does not detect the wake-up signal, it will not start the first time window. It can be understood that the terminal will not resume the first time window if it does not detect the wake-up signal. Length of PDCCH monitoring.

In other embodiments, within the skipped PDCCH listening period or outside the activation time, if the terminal detects the wake-up signal, it starts the first time window; if the terminal does not detect the wake-up signal, it does not start the first time window. In another embodiment, the network side device configuration or protocol stipulates that the wake-up signal sequence 1 represents starting the first time window. Therefore, within the skipped PDCCH listening time period or outside the activation time, if the terminal detects the wake-up signal sequence 1, it starts the first time window. It can be understood as: when the terminal detects the wake-up signal sequence 1, it resumes the length of the first time window. PDCCH monitoring; optionally, if the terminal does not detect the wake-up signal or detects that it is not wake-up signal sequence 1, the first time window will not be started.

It should be noted that not starting the first time window can be understood as canceling the first time window or skipping the first time window. At this time, the corresponding behavior of the terminal is not to perform the first PDCCH monitoring.

Optionally, the network side device configuration or protocol stipulates that the terminal does not activate the first time window within the PDCCH skipping listening time period or outside the activation time by default, which can be understood as: the terminal defaults to the PDCCH skipping listening time period or activates PDCCH monitoring of the first time window length will not be resumed outside the time.

Optionally, the first time window can be understood as the listening time window of the first PDCCH. In this embodiment, the network side device configuration or protocol agrees on the length of a first time window, for example, 2 ms. The above-mentioned first PDCCH may be a PDCCH of a specific search space type, such as a Type 3 common search space (Common Search Space, CSS) and a user equipment-specific search space (UE-specific search space, USS) PDCCH.

Through the method of the embodiment of the present application, the terminal can determine whether to start the first time window or determine whether to restore the first time window length by monitoring the wake-up signal during the skipped PDCCH listening time period or outside the activation time. PDCCH monitoring. Since the power consumption of monitoring the wake-up signal is very low, the terminal can flexibly determine whether to resume PDCCH monitoring of the first time window length by monitoring the wake-up signal, and can avoid the waste of power consumption caused by unnecessary PDCCH monitoring. It can also be used when there is When necessary, resume PDCCH monitoring in a timely manner to ensure communication quality.
