Description

Method and device for monitoring PDCCH

The present application claims priority of chinese patent application entitled "a method and apparatus for monitoring PDCCH" filed by chinese patent office on 29/03/2019 with application number 201910253490.9, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for monitoring a PDCCH.

Background

In the fifth generation new air port (5)^thGeneration New relay, 5G NR) system, in order to obtain Downlink data, a terminal device needs to monitor a Physical Downlink Control Channel (PDCCH) to determine whether there is Downlink scheduling information. The process of monitoring the PDCCH comprises the following steps: the terminal device performs PDCCH decoding, and then determines whether the PDCCH is Downlink Control Information (DCI) carrying scheduling Information of the terminal device through Cyclic Redundancy Check (CRC).

Currently, a Discontinuous Reception (DRX) monitoring mechanism is generally adopted in a method for monitoring a PDCCH, and a terminal device monitors the PDCCH when a DXR active period (DRX on duration) or an Inactivity timer (Inactivity timer) in a DRX cycle is not expired.

It can be seen that the number of monitoring times in the existing PDCCH monitoring manner depends on the DRX cycle, and the flexibility of monitoring the PDCCH is poor.

Detailed Description

In order to better understand the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the drawings and specific embodiments.

In order to better understand the technical solutions in the embodiments of the present application, the following describes the prior art related to the present application.

Referring to fig. 1, in the conventional DRX monitoring mechanism, a DRX cycle includes a DXR active period (DRX on duration) and a DRX inactive period (DRX off). The terminal equipment monitors the PDCCH during the DXR activation period and does not monitor the PDCCH during the DRX deactivation period.

Currently, in the DRX monitoring mechanism, the number of times that the terminal device monitors the PDCCH depends on the DRX cycle, and if the DRX cycle is one monitoring opportunity (PDCCH monitoring interference), the terminal device will monitor the PDCCH in each monitoring opportunity. As can be seen, in the prior art, the mode for monitoring the PDCCH has poor flexibility.

In view of this, an embodiment of the present application provides a method for monitoring a PDCCH, and a usage scenario of the method is described below.

Referring to fig. 2, the usage scenario includes a network device and a terminal device. The network device and the plurality of terminal devices can communicate with each other. The network equipment sends PDCCH monitoring indication information to the terminal equipment, and the terminal equipment executes the next PDCCH monitoring action according to the PDCCH monitoring indication information after receiving the PDCCH monitoring indication information. The following describes a specific communication procedure of the network device and the terminal device.

It should be noted that fig. 2 illustrates two terminal devices, but the number of terminal devices is not limited in practice.

The terminal device may be a wireless terminal or a wired terminal, and the wireless terminal may be a device providing voice and/or other service data connectivity to a user, a handheld device having a wireless connection function, or other processing devices connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an access Terminal (access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Equipment (User Equipment).

The Network device may be a device for communicating with a terminal device, where the Network device may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in a WCDMA system, an evolved node b (Evo1utiona1 NodeB, eNB, or eNodeB) in an LTE system, a wireless controller in a cloud Radio Access Network (C1 output Radio Access Network, CRAN) scenario, or a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a 5G Network, a Network device in a future evolved PLMN Network, or the like, and a specific type of the Network device is not limited in this embodiment.

Referring to fig. 3 on the basis of the scenario discussed in fig. 2, fig. 3 is a schematic view illustrating an interaction flow between a network device and a terminal device, and the following describes a method for monitoring a PDCCH in the embodiment of the present application with reference to fig. 3.

Step 301, the network device sends PDCCH monitoring indication information to the terminal device.

Specifically, the network device may send the PDCCH monitoring indication information to multiple terminal devices at the same time, for example, the network device may send the PDCCH monitoring indication information to terminal devices within the coverage of the network device at the same time. The network device may also send PDCCH monitoring indication information to each terminal device at irregular time according to the current data transmission condition of each terminal device, or the network device may send PDCCH monitoring indication information to each terminal device at preset time intervals.

And the PDCCH monitoring indication information is used for indicating the PDCCH monitoring action next time. The next PDCCH monitoring behavior may be understood as various information used to instruct the terminal device to perform the next PDCCH monitoring behavior, such as the time or period of the next PDCCH monitoring, whether to perform the next PDCCH monitoring behavior on the next PDCCH monitoring opportunity, and the like. The PDCCH monitoring indication information will be specifically described below.

Wherein, the PDCCH monitoring indication information includes one or more of the following:

(1) information indicating whether to skip a next PDCCH monitoring behavior;

(2) information indicating a monitoring time of a next PDCCH monitoring behavior;

(3) information indicating whether a monitoring period of a next PDCCH monitoring behavior is changed;

(4) information indicating a monitoring period for a next PDCCH monitoring activity.

The following is a detailed description of the above four information.

(1) Information indicating whether to skip the next PDCCH monitoring action:

the information indicating whether to skip the next PDCCH monitoring action is used to indicate that the PDCCH is monitored at the next PDCCH monitoring opportunity, or the information indicating whether to skip the next PDCCH monitoring action is used to indicate that the PDCCH monitoring is skipped at the next PDCCH monitoring opportunity.

For example, the network device employs 1bit to represent information indicating whether to skip the next PDCCH monitoring behavior. When the information indicating whether to skip the next PDCCH monitoring behavior is a first value, for example, "0", the information indicating that the terminal device is to perform PDCCH monitoring at the next PDCCH monitoring opportunity. When the information indicating whether to skip the next PDCCH monitoring behavior is a second value, e.g., "1", it indicates that the UE needs to skip PDCCH monitoring.

As an embodiment, when the PDCCH monitoring indication information includes only information indicating whether to skip the next PDCCH monitoring action, and the information indicating whether to skip the next PDCCH monitoring action is used to indicate that monitoring of the PDCCH is skipped at the next PDCCH monitoring opportunity. The network device may carry information indicating a next PDCCH monitoring time of the terminal device in the high-level signaling, and send the next PDCCH monitoring time to the terminal device through the high-level signaling.

The PDCCH monitoring opportunity (PDCCH monitoring occasion) refers to the behavior of PDCCH candidate detection performed by the terminal device on one PDCCH search space. The PDCCH search space is configured periodically.

For example, referring to fig. 4, the period of the PDCCH search space is 2 slots apart, and each 2 slots correspond to one PDCCH monitoring opportunity (e.g., O1 and O2 in fig. 4). The current time slot is the 0 th time slot (TS0), and PDCCH monitoring is currently performed, the next PDCCH monitoring opportunity is located on the second time slot (TS 2).

(2) Information indicating a monitoring time of a next PDCCH monitoring activity:

the information for indicating the monitoring time of the next PDCCH monitoring activity is used to indicate that PDCCH monitoring is performed on the nth PDCCH monitoring opportunity, where N is an integer.

The nth is the first PDCCH monitoring opportunity which is the next monitoring opportunity of the terminal device as a counting reference.

For example, the information indicating the monitoring time of the next PDCCH monitoring behavior is represented by two bits, and when the information indicating the monitoring time of the next PDCCH monitoring behavior is 00, the terminal device is indicated to perform PDCCH monitoring at the next PDCCH monitoring opportunity. When the information is 01, the terminal device is instructed to perform PDCCH monitoring at the nth 1 PDCCH monitoring opportunity. When the information is 10, the terminal device is instructed to perform PDCCH monitoring at the nth 2 PDCCH monitoring opportunity. When the information is 11, the terminal device is instructed to perform PDCCH monitoring at the nth 3 PDCCH monitoring opportunity.

(3) Information indicating whether a monitoring period of a next PDCCH monitoring behavior changes:

the information for indicating whether the monitoring period of the next PDCCH monitoring behavior is changed is used for indicating that the monitoring period of PDCCH monitoring is not changed; or, the information indicating whether the monitoring period of the next PDCCH monitoring behavior is changed is used to indicate that the monitoring period of the PDCCH monitoring is changed.

When the PDCCH monitoring indication information only includes information for indicating whether the monitoring period of the next PDCCH monitoring behavior changes, and the information for indicating whether the monitoring period of the next PDCCH monitoring behavior changes is used for indicating that the monitoring period of the PDCCH monitoring behavior changes, the terminal device cannot know the changed monitoring period, the network device can carry the changed monitoring period in a high-level signaling, the PDCCH monitoring period is sent to the terminal device in a set through the high-level signaling, and the network device can also carry an index value of the changed monitoring period in the high-level signaling.

For example, the information indicating whether the monitoring period of the next PDCCH monitoring behavior is changed is represented by a 1-bit indication, and the information is used to indicate whether the PDCCH monitoring period is changed. If the indication information is a third value, for example, "0", the UE is indicated not to change the PDCCH monitoring period, that is, the PDCCH monitoring is performed according to a monitoring period K preconfigured in the high layer signaling, and if K is 1, each PDCCH monitoring opportunity performs PDCCH monitoring; if the information is a fourth value, for example, "1", for indicating that the UE needs to change the PDCCH monitoring period, the changed PDCCH monitoring period is configured by higher layer signaling.

(4) Information indicating a monitoring period for a next PDCCH monitoring behavior:

the information for indicating the monitoring period of the next PDCCH monitoring behavior is used to indicate the modified monitoring period of the PDCCH, or is used to indicate an index value in a PDCCH monitoring period set in which the modified PDCCH monitoring period is located.

When the PDCCH monitoring indication information is used to indicate information of a monitoring period of a next PDCCH monitoring behavior, and the information used to indicate the monitoring period of the next PDCCH monitoring behavior specifically indicates an index value in a PDCCH monitoring period set where the changed PDCCH monitoring period is located, in order to enable the terminal device to obtain a corresponding PDCCH monitoring period according to the index value, the network device may carry the PDCCH monitoring period set in a high-level signaling, and send the PDCCH monitoring period set to the terminal device through the high-level signaling.

Herein, the higher layer signaling includes, for example, Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, and the like.

For example, the preconfigured set of PDCCH monitoring periods for higher layer signaling is { K1 PDCCH monitoring opportunities, K2 PDCCH monitoring opportunities, K3 PDCCH monitoring opportunities, K4 PDCCH monitoring opportunities }. And when the information indicating the monitoring period of the next PDCCH monitoring action is "00", indicating that the terminal device performs PDCCH monitoring at K1 PDCCH monitoring opportunities. And when the information for indicating the monitoring period of the next PDCCH monitoring action is "01", indicating that the terminal device performs PDCCH monitoring at K2 PDCCH monitoring opportunities. And when the information indicating the monitoring period of the next PDCCH monitoring action is '10', indicating that the terminal device performs PDCCH monitoring at every K3 PDCCH monitoring opportunities. And when the information for indicating the monitoring period of the next PDCCH monitoring action is "11", indicating that the terminal device performs PDCCH monitoring on every K4 PDCCH monitoring opportunities.

There are many ways to combine the 4 types of PDCCH monitoring indication information, and the following describes an example of combining the 4 types of PDCCH monitoring indication information.

Example one, the PDCCH monitoring indication information includes (1) and (2):

specifically, the PDCCH monitoring indication information is used to indicate that the terminal device skips the next PDCCH monitoring action on the next monitoring opportunity, and the monitoring time of the next PDCCH monitoring action is on the nth monitoring opportunity. Or, the DCCH monitoring indication information is used to indicate that the terminal device does not skip the next PDCCH monitoring action on the next monitoring opportunity, and the monitoring time of the next PDCCH monitoring action is on the N1 th monitoring opportunity.

For example, two bits are used to represent the PDCCH monitoring indication information, and when the PDCCH monitoring indication information is "00", the terminal device is instructed not to skip PDCCH monitoring at the next monitoring opportunity. When the PDCCH monitoring indication information is "10", the terminal device is instructed not to skip PDCCH monitoring at the next monitoring opportunity, and the next monitoring action performs PDCCH monitoring at the 2 nd monitoring opportunity.

In the PDCCH monitoring indication information in the first example, since the PDCCH monitoring indication information carries a time for indicating the terminal device to perform the next monitoring action, the terminal device does not need to configure the time for performing the PDCCH monitoring for the terminal device through a high-level signaling, and compared with the PDCCH monitoring indication information in (1), the network transmission burden can be reduced.

Example two, the PDCCH monitoring indication information includes (3) and (4):

specifically, the terminal device is configured to instruct to change a monitoring period of a next PDCCH monitoring behavior, and the monitoring period of the next PDCCH monitoring behavior. Or a monitoring period for indicating that the next PDCCH monitoring behavior is not changed.

For example, two bits are used to represent the PDCCH monitoring indication information, and when the PDCCH monitoring indication information is "00", the terminal device is instructed not to change the monitoring period of the next PDCCH monitoring action. When the PDCCH monitoring indication information is "10", the terminal device is instructed to change the monitoring period of the next PDCCH monitoring behavior, and the changed PDCCH monitoring period is one PDCCH monitoring at every 2 monitoring opportunities.

In the PDCCH monitoring indication information in example two, since the PDCCH monitoring indication information carries information for indicating the PDCCH monitoring period after the terminal device is changed, it is not necessary for the terminal device to configure the PDCCH monitoring period after the change for the terminal device through a high-level signaling, and compared with the PDCCH monitoring indication information in (3), the network transmission burden can be reduced.

In a possible embodiment, when the network device determines that the current service of the terminal device is a burst service and has preconfigured scheduling resources for the terminal device, or when the number of downlink services of the terminal device is less than the preset number of services, the network device may instruct the terminal device to reduce PDCCH monitoring behavior by issuing PDCCH monitoring indication information, so as to avoid unnecessary PDCCH monitoring.

Specifically, the network device may instruct the terminal device to skip PDCCH monitoring on the next PDCCH monitoring opportunity through the PDCCH monitoring instruction information, and/or instruct the terminal device to set the monitoring period to be longer, so as to reduce the behavior of the terminal device in monitoring the PDCCH.

There are many ways to combine the 4 PDCCH monitoring indication information, which are only two examples, and are not limited to the two combining ways.

The following describes a manner in which the network device transmits PDCCH monitoring indication information.

The first method is as follows:

and the network equipment sends the PDCCH monitoring indication information to the terminal equipment through the downlink signaling.

Specifically, the network device carries PDCCH monitoring indication information in a downlink signaling, and sends the PDCCH monitoring indication information to the terminal device through the downlink signaling, where the downlink signaling generally refers to a signaling for indicating downlink transmission, and the downlink signaling herein carries the PDCCH monitoring indication information in addition to scheduling information for indicating the terminal device to perform downlink data transmission. The downlink signaling includes various signaling such as DCI and a Medium Access Control element (MAC CE). The network device may send the PDCCH monitoring indication information through one of the multiple downlink signaling, or may send the PDCCH monitoring indication information through the multiple downlink signaling. The PDCCH monitoring indication information is sent through various downlink signaling, so that the reliability of the terminal equipment for receiving the PDCCH monitoring indication information can be improved.

The network device carries the PDCCH monitoring indication in DCI, and sends PDCCH monitoring indication information to the terminal device through the DCI, for example, the network device carries the PDCCH monitoring indication in DCI of format 1_0 or format 1_ 1.

Or, the network device carries the PDCCH monitoring indication in the MAC CE, and the network device sends the PDCCH monitoring indication information to the terminal device through the MAC CE.

For example, the network device carries a PDCCH monitoring information indication in the MAC CE, where the PDCCH monitoring information indication may be 1-bit information or 2-bit information. Taking the PDCCH monitoring information indication of 1bit information as an example, and the PDCCH monitoring information indication is whether the terminal device changes the PDCCH monitoring period.

If the PDCCH monitoring indication information is "0", the terminal device is instructed not to change the PDCCH monitoring period during DRX activation, that is, the terminal device performs PDCCH monitoring at a monitoring period K preconfigured by high layer signaling, for example, K is 1, and each PDCCH monitoring opportunity performs PDCCH monitoring.

And if the PDCCH monitoring indication information is '1', indicating that the terminal equipment changes the PDCCH monitoring period during the DRX activation period, wherein the changed PDCCH monitoring period is carried in a high-level signaling.

In the first mode, the PDCCH monitoring indication information is carried by the existing downlink signaling, so that the network transmission load can be relatively reduced.

The second method comprises the following steps:

and the network equipment sends the PDCCH monitoring indication information to the terminal equipment through the special signaling.

Specifically, the network device carries the PDCCH monitoring indication information in the dedicated information, and sends the PDCCH monitoring indication information to the terminal device through the dedicated signaling. For example, the network device may periodically transmit PDCCH monitoring indication information to the terminal device through dedicated signaling. The dedicated signaling refers to information that is issued by the network device and can separately implement some functions, such as power saving signals.

As an embodiment, at each PDCCH monitoring time, the network device sends PDCCH monitoring indication information through dedicated signaling.

As an embodiment, when it is determined that new downlink data to be transmitted reaches the terminal device at the next PDCCH monitoring opportunity, the network device may be carried in a dedicated signaling for instructing the terminal device to perform PDCCH monitoring at the next PDCCH monitoring opportunity, so as to avoid that the terminal device misses receiving the downlink data.

As an embodiment, when determining that new downlink data to be transmitted reaches the terminal device at the skipped next PDCCH monitoring opportunity, that is, according to the indication of the current PDCCH indication information, the terminal device skips monitoring at the next PDCCH monitoring opportunity, but the network device determines that the downlink data may reach at the next PDCCH monitoring opportunity, the network device may carry a dedicated signaling for instructing the terminal device to perform PDCCH monitoring at the next PDCCH monitoring opportunity, so as to avoid the terminal device missing to receive the downlink data.

The format of the dedicated signaling may be a physical layer reference signal format of a reference sequence, or a DCI format, or a MAC CE format, or a Radio Resource Control (RRC) signaling format, and the format of the dedicated signaling is not limited herein.

In the second mode, the network device sends the PDCCH monitoring indication information through the dedicated signaling, the network device can set and send the dedicated signaling according to the actual situation, and the dedicated signaling and the data transmission process can be independent from each other, that is, the dedicated signaling can not be affected by the data transmission process, so the network device can determine when to send the dedicated signaling according to the actual requirement, and the flexibility of monitoring the PDCCH is further improved.

The third method comprises the following steps:

and the network equipment sends PDCCH monitoring indication information to the terminal equipment through a downlink signaling, and sends the PDCCH monitoring indication information to the terminal equipment through a special signaling.

Specifically, the network device carries PDCCH monitoring indication information in both the downlink signaling and the dedicated signaling, and the network device determines whether to send the PDCCH monitoring indication information through the downlink signaling or send the PDCCH monitoring indication information through the dedicated signaling according to the current data transmission condition of the terminal device, or the network device issues the PDCCH monitoring indication information through the downlink signaling and the dedicated signaling.

First case of the third mode:

and the network equipment sends the PDCCH monitoring indication information to the terminal equipment through the downlink signaling and the special signaling.

Specifically, no matter how the current data transmission condition of the terminal device is, the network device sends the PDCCH monitoring indication information through the downlink signaling, and sends the PDCCH monitoring indication information through the dedicated signaling, so as to ensure that the terminal device can receive the PDCCH monitoring indication information.

The downlink signaling is sent by the network device according to the corresponding downlink data transmission process, and therefore the downlink signaling may be sent at irregular time, and therefore, the downlink signaling sent by the network device and the dedicated signaling may be synchronous or asynchronous. Regardless of whether the downlink signaling and the dedicated signaling are sent synchronously or asynchronously, the PDCCH monitoring indication information carried in the downlink signaling and the PDCCH monitoring indication information carried in the dedicated signaling include the same information type, but the specific content of the information indicated by the PDCCH monitoring indication information may be the same or different.

For example, the downlink signaling and the dedicated signaling are configured to synchronously send PDCCH monitoring indication information, where the downlink signaling is carried in order to indicate the terminal device to perform PDCCH monitoring on the 2 nd monitoring opportunity, and the dedicated signaling is carried in order to indicate the terminal device to perform monitoring on the 3 rd monitoring opportunity.

After receiving the corresponding downlink signaling and the dedicated signaling, the terminal device takes which signaling indicates the PDCCH monitoring indication information as the standard, and the following description will be specifically made when introducing that the terminal device receives the PDCCH monitoring indication information.

Second case of the third mode:

when the network device indicates that the terminal device does not skip the PDCCH monitoring on the last PDCCH monitoring opportunity, that is, the terminal device does not trigger the skipping of the PDCCH monitoring, the network device preferentially sends PDCCH monitoring indication information through a downlink signaling. When the network device instructs the terminal device to skip the PDCCH monitoring on the last PDCCH monitoring opportunity, that is, under the condition that the terminal device triggers the skipping of the PDCCH monitoring, the network device preferentially sends PDCCH monitoring indication information through a dedicated signaling.

Specifically, when the network device indicates that the terminal device does not skip PDCCH monitoring on the last PDCCH monitoring opportunity, the network device determines that there is downlink data to be transmitted, or the network device is currently in the process of transmitting the downlink data, and the network device may send PDCCH monitoring indication information through a downlink signaling.

The network device determines that the transmission of the downlink data is completed or no downlink data to be transmitted exists, and the network device can send the PDCCH monitoring indication information through a dedicated signaling.

When the network equipment indicates the terminal equipment to skip the PDCCH monitoring on the last PDCCH monitoring opportunity, the network equipment preferentially issues PDCCH monitoring indication information through a dedicated signaling, if the network equipment determines that downlink data to be transmitted exists on a certain monitoring opportunity, the network equipment can issue the PDCCH monitoring indication information for indicating the terminal equipment to perform the PDCCH monitoring on the monitoring opportunity through the dedicated signaling, and after the terminal equipment performs the PDCCH monitoring on the monitoring opportunity, the network equipment preferentially issues the PDCCH monitoring indication information through the downlink signaling.

The last PDCCH monitoring opportunity refers to a monitoring opportunity on a time slot closest to the current time slot in a time slot before the current time slot.

In the second case of the third mode, the mode of sending the PDCCH next time is determined according to whether the PDCCH monitoring is skipped on the current monitoring opportunity, and a mode of flexibly switching sending PDCCH monitoring indication information is provided.

As an embodiment, when determining that there is new downlink data to be transmitted, the network device may carry information in the downlink signaling for instructing the terminal device to perform PDCCH monitoring on the next PDCCH monitoring opportunity, so as to avoid that the terminal device misses receiving the downlink data.

As an embodiment, when determining that new downlink data to be transmitted reaches the terminal device at the skipped next PDCCH monitoring opportunity, that is, according to the indication of the current PDCCH indication information, the terminal device skips monitoring at the next PDCCH monitoring opportunity, but the network device determines that the downlink data may reach at the next PDCCH monitoring opportunity, the network device may carry information in the downlink signaling for instructing the terminal device to perform PDCCH monitoring at the next PDCCH monitoring opportunity, so as to avoid the terminal device missing to receive the downlink data.

For example, when the network device determines downlink data to be transmitted, or during the downlink data transmission process, the network device may send PDCCH monitoring indication information through the DCI, where the PDCCH monitoring indication information is "0" and is used to indicate that the terminal device needs to monitor the PDCCH at the next time.

The network device may send PDCCH monitoring indication information through DCI at the last time of downlink data transmission, where the PDCCH monitoring indication information is "1" and is used to indicate that the terminal device needs to monitor the PDCCH at the next PDCCH monitoring opportunity, and the PDCCH monitoring indication information is used to indicate that the UE may skip the next PDCCH monitoring opportunity. When the network equipment determines that the terminal equipment does not have downlink data to be transmitted, the network equipment sends the PDCCH monitoring indication information to the terminal equipment through a special signaling.

After the network device performs step 301, please continue to refer to fig. 3, the terminal device performs step 302, i.e. performs the next PDCCH monitoring action according to the PDCCH monitoring indication information.

Specifically, since the PDCCH monitoring indication information may be carried in different signaling, the terminal device needs to analyze the corresponding signaling to obtain the PDCCH monitoring indication information. The following describes an exemplary manner in which the terminal device acquires PDCCH monitoring indication information. The PDCCH monitoring indication information may refer to the content discussed above, and is not described herein again.

The first method comprises the following steps:

and under the condition that the terminal equipment transmits downlink signaling through the network equipment, acquiring the PDCCH monitoring indication information.

Specifically, when the network device sends the PDCCH monitoring indication information in the manner discussed above, or when the network device sends the PDCCH monitoring indication information in the manner discussed above, the terminal device may obtain the PDCCH monitoring indication information through downlink signaling. The downlink signaling may refer to the content discussed above, and is not described in detail here.

The network device obtains the PDCCH monitoring indication information in a downlink signaling manner, for example, obtains the PDCCH monitoring indication information in the downlink signaling through Cyclic Redundancy Check (CRC) Check.

And the second method comprises the following steps:

and under the condition that the terminal equipment transmits the special signaling through the network equipment, acquiring the PDCCH monitoring indication information.

Specifically, when the network device transmits PDCCH monitoring indication information in the manner discussed above, or when the network device transmits PDCCH monitoring indication information in the manner discussed above, the terminal device may obtain the PDCCH monitoring indication information through dedicated signaling. The dedicated signaling can refer to the content discussed in the foregoing, and is not described in detail here. The terminal device can analyze the dedicated signaling at each PDCCH monitoring time to obtain corresponding PDCCH monitoring indication information.

The terminal device may obtain the PDCCH monitoring indication information in the dedicated signaling through a corresponding checking process, where the checking includes, but is not limited to, a CRC check.

And the third is that:

and the terminal equipment acquires the PDCCH monitoring indication information through the special signaling and the downlink signaling sent by the network equipment.

First case of the third:

in the case that the network device sends the PDCCH monitoring indication information in the first case of the third mode, the terminal device may obtain the PDCCH monitoring indication information through the dedicated signaling, and may obtain the PDCCH monitoring indication information through the downlink signaling.

If the network device synchronously sends the same PDCCH monitoring indication information through the downlink signaling and the dedicated signaling, the terminal device can obtain the PDCCH monitoring indication information through any one or two of the downlink signaling and the dedicated signaling.

As an embodiment, the network device sends the PDCCH monitoring indication information synchronously through the downlink signaling and the dedicated signaling, and in order to reduce the processing load of the terminal device, the terminal device may parse the default signaling with the highest priority, obtain the PDCCH monitoring indication information indicated by the signaling with the highest priority, and execute the next PDCCH monitoring action according to the PDCCH monitoring indication information indication.

For example, the priority of the default downlink signaling in the terminal device is higher than that of the dedicated signaling, when the terminal device receives the downlink signaling and the dedicated signaling, the terminal device may directly obtain the PDCCH monitoring indication information according to the downlink signaling, and the terminal device is subject to the PDCCH monitoring indication information.

If the network device asynchronously sends the same PDCCH monitoring indication information through the downlink signaling and the dedicated signaling, the terminal device regards the latest received PDCCH monitoring indication information as the standard, and the latest reception can be further understood as the PDCCH monitoring indication information received at the time closest to the current time.

Second case of the third:

under the condition that the network equipment sends the PDCCH monitoring indication information through the second condition in the third mode, when the terminal equipment does not skip the PDCCH monitoring on the last PDCCH monitoring opportunity, if the terminal equipment can obtain the PDCCH monitoring indication information through downlink signaling in the transmission process of downlink data; and if the downlink data to be transmitted does not exist, the terminal equipment acquires the PDCCH monitoring indication information according to the special signaling sent by the network equipment. When the terminal device skips the PDCCH monitoring on the last PDCCH monitoring opportunity, the terminal device preferentially obtains the PDCCH monitoring indication information through the dedicated signaling, if the terminal device does not obtain the PDCCH monitoring indication information through the dedicated signaling, the network abnormality is determined, and the terminal device can execute the next PDCCH monitoring indication behavior according to the indication of the last PDCCH monitoring indication information. The content of the last PDCCH monitoring indication information may refer to the content discussed above, and is not described herein again.

Third case of the third:

when the network device sends the PDCCH monitoring indication information in the manner discussed above, the terminal device will firstly analyze the downlink signaling, and if it is determined that the downlink signaling carries the PDCCH monitoring indication information, the terminal device obtains the PDCCH monitoring indication information according to the downlink signaling; and if the terminal equipment determines that the downlink signaling does not carry the PDCCH monitoring indication information after analyzing the downlink signaling, the terminal equipment obtains the PDCCH monitoring indication information according to the special signaling. The terminal device may resolve the downlink signaling at each PDCCH monitoring time.

In a possible embodiment, the terminal device does not receive the downlink signaling and the dedicated signaling carrying the PDCCH monitoring indication information due to other reasons such as network anomaly, and the terminal device may perform PDCCH monitoring according to the manner indicated by the previous PDCCH monitoring indication information.

Specifically, the terminal device does not receive the downlink signaling carrying the PDCCH monitoring indication information and the dedicated signaling, and may specifically include two cases, which are described below:

in the first case, the terminal device receives the corresponding downlink signaling and the dedicated signaling, but the terminal device does not resolve the PDCCH monitoring indication information according to the downlink signaling and the dedicated signaling.

In the second case, the terminal device does not receive the downlink signaling, and the dedicated signaling.

When the terminal device does not receive the downlink signaling and the dedicated signaling carrying the PDCCH monitoring indication information, the terminal device may perform PDCCH monitoring according to the mode indicated by the previous PDCCH monitoring indication information. The last PDCCH monitoring indication information may be understood as PDCCH monitoring indication information received at a time closest to the current time by the terminal device.

For example, the terminal device does not receive the downlink signaling and the dedicated signaling carrying the PDCCH monitoring indication information due to other reasons such as network anomaly, and the terminal device determines that the last PDCCH monitoring indication information indicates that the terminal device does not skip PDCCH monitoring at the next PDCCH monitoring opportunity, and the terminal device may not skip PDCCH monitoring at the current next PDCCH monitoring opportunity.

Or for example, the terminal device does not receive the downlink signaling and the dedicated signaling carrying the PDCCH monitoring indication information, the terminal device determines that the last PDCCH monitoring indication information indicates that the terminal device skips PDCCH monitoring at the next PDCCH monitoring opportunity, and the terminal device may skip PDCCH monitoring at the current next PDCCH monitoring opportunity.

After obtaining the PDCCH monitoring indication information, the terminal device monitors the PDCCH according to the content of the monitored PDCCH indicated by the PDCCH monitoring indication information. Since the content possibly indicated by the PDCCH monitoring indication information is different, the behavior of the terminal device performing the next PDCCH monitoring is also different. Different PDCCH monitoring indication information and PDCCH monitoring behaviors corresponding to the terminal device are introduced below.

A1, the PDCCH monitoring indication information includes information indicating whether to skip the next PDCCH monitoring action on the next PDCCH monitoring opportunity.

Specifically, the terminal device obtains the PDCCH monitoring indication information to indicate that the terminal device does not skip the PDCCH monitoring action at the next PDCCH monitoring opportunity, and then the terminal device monitors the PDCCH at the next PDCCH monitoring opportunity. The terminal device obtains the PDCCH monitoring indication information to indicate that the terminal device skips the PDCCH monitoring action on the next PDCCH monitoring opportunity, and then the terminal device monitors the PDCCH on the next PDCCH monitoring opportunity, and the terminal device can determine the time of the next PDCCH monitoring action according to the next PDCCH monitoring time preconfigured in the high-level signaling.

For example, referring to fig. 4 again, in the time slot TS0, the PDCCH monitoring indication information indicates that the terminal device skips PDCCH monitoring on the current PDCCH monitoring opportunity, and the high-level signaling is preconfigured with the terminal device to perform PDCCH monitoring once every two monitoring opportunities, so that the terminal device performs PDCCH monitoring on the PDCCH monitoring opportunity corresponding to the time slot TS2 after skipping PDCCH monitoring at TS 0.

A2, the PDCCH monitoring indication information includes information for indicating the monitoring time of the next PDCCH monitoring action.

Specifically, the terminal device obtains the PDCCH monitoring indication information for indicating the terminal device to monitor at the nth monitoring opportunity, and the terminal device determines to monitor at the nth monitoring opportunity according to the PDCCH monitoring indication information.

For example, referring to fig. 4, if the terminal device receives PDCCH monitoring indication information on the time slot TS1, and the PDCCH monitoring indication information indicates that monitoring is performed on the 1 st monitoring opportunity, the terminal device monitors the PDCCH on the time slot TS 2.

A3, the PDCCH monitoring indication information includes information indicating whether a monitoring period of a next PDCCH monitoring action is changed.

Specifically, the terminal device obtains the PDCCH monitoring indication information for the terminal device to monitor the PDCCH continuously according to the monitoring period preconfigured in the high-level signaling without changing the monitoring period of the PDCCH monitoring behavior at the next time. And the terminal equipment obtains the PDCCH monitoring indication information for the monitoring period change of the next PDCCH monitoring behavior of the terminal equipment, and then the terminal equipment determines the changed PDCCH monitoring period according to the received high-level signaling.

There are two ways for the terminal device to determine the changed PDCCH monitoring period according to the received high-level signaling, which will be described below.

The high-level signaling carries the changed monitoring period, and the terminal equipment obtains the changed monitoring period according to the high-level signaling. Or, the high-level signaling carries an index value corresponding to the changed monitoring period, and the terminal device determines the changed monitoring period according to the index value.

A4, the PDCCH monitoring indication information includes information for indicating a monitoring period of a next PDCCH monitoring action.

Specifically, the PDCCH monitoring indication information carries a corresponding PDCCH monitoring period, and the terminal device obtains the monitoring period of the next PDCCH monitoring behavior according to the PDCCH monitoring indication information. Or the PDCCH monitoring indication information carries an index value in the PDCCH monitoring period set where the changed PDCCH monitoring period is located, and the terminal device obtains the monitoring period of the next PDCCH monitoring behavior according to the PDCCH monitoring period set preconfigured by the high-level signaling and the index value.

A5, the PDCCH monitoring indication information includes information for indicating whether to skip the next PDCCH monitoring action and information for indicating a monitoring time of the next PDCCH monitoring action.

Specifically, the terminal device determines to skip the PDCCH monitoring on the next monitoring opportunity according to the PDCCH monitoring indication information, and determines the time for performing the PDCCH monitoring next time according to the PDCCH monitoring indication information. Or the terminal equipment determines not to skip the PDCCH monitoring on the next monitoring opportunity according to the PDCCH monitoring indication information.

A6, the PDCCH monitoring indication information includes information indicating whether a monitoring period of a next PDCCH monitoring action is changed and information indicating a monitoring period of a next PDCCH monitoring action.

Specifically, the terminal device determines, according to the PDCCH monitoring indication information, a monitoring period for changing a next PDCCH monitoring behavior, and determines a specific value of the monitoring period for the next PDCCH monitoring behavior. Or the terminal equipment determines not to change the monitoring period of the next PDCCH monitoring behavior according to the PDCCH monitoring indication information.
