For ease of understanding, the concepts related to the present application will first be explained.

A network device: the Network device may be a device for communicating with the terminal device, for example, the Network device may be a Base Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) Communication System, a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, an evolved Node B (eNB, or eNodeB) in an LTE System, or the Network device may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network-side device in a future 5G Network or a Network after 5G Network, or a Network device in a future evolved Public Land Mobile Network (PLMN) Network, and the like.

The Network device related in the embodiment of the present application may also be referred to as a Radio Access Network (RAN) device. The RAN equipment is connected with the terminal equipment and used for receiving data of the terminal equipment and sending the data to the core network equipment. RAN devices correspond to different devices in different communication systems, for example, a base station and a base station Controller in a 2G system, a base station and a Radio Network Controller (RNC) in a 3G system, an evolved Node B (eNB) in a 4G system, and an access Network device (e.g., a gNB, a central unit CU, a distributed unit DU) in a 5G system, such as an NR.

Next, a scenario to which the communication method of the present application is applied will be described with reference to fig. 1.

Fig. 1 is a schematic diagram of a communication scenario provided in an embodiment of the present application. Referring to fig. 1, a network device 101 and a terminal device 102 are included, and wireless communication can be performed between the network device 101 and the terminal device 102.

The Network including the Network device 101 and the terminal device 102 may also be referred to as a Non-Terrestrial communication Network (NTN), where NTN refers to a communication Network between the terminal device and a satellite (which may also be referred to as a Network device).

It is understood that the technical solution of the embodiment of the present invention can be applied to New Radio (NR) communication technology, where NR refers to New Generation Radio access network technology, and can be applied to future evolved networks, such as the 5th Generation Mobile communication (5g) system. The scheme in the embodiment of the application can also be applied to other Wireless communication networks such as Wireless Fidelity (WIFI) and Long Term Evolution (LTE), and the corresponding names can also be replaced by names of corresponding functions in other Wireless communication networks.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The following further details the related technical background of the present application:

in order to reduce the power consumption of the terminal device, the NR system supports the terminal device to perform Discontinuous Reception (DRX), where DRX refers to turning off a receiving circuit of the terminal device to reduce the power consumption when there is no data transmission, such as a PDCCH that monitors data transmission discontinuously.

DRX cycles (DRX cycles) may be preset by the network device, one DRX cycle including an active period (On Duration) and an inactive period. The terminal equipment monitors the PDCCH in the active period, and the terminal equipment does not monitor the PDCCH in the inactive period. Next, the DRX cycle will be described with reference to fig. 2.

Fig. 2 is a schematic diagram of a DRX cycle according to an embodiment of the present disclosure. Referring to fig. 2, the drx cycle includes an active period and an inactive period.

When the terminal equipment is in an activation period, the terminal equipment enters an awakening state so as to monitor and receive the PDCCH or perform related measurement, and if the received PDCCH indicates data sent to the terminal equipment by the network equipment, the terminal equipment receives the data at a specified time-frequency position.

And when the terminal equipment is in the inactive period, the terminal equipment enters a dormant state and does not monitor the PDCCH.

If the set period of the activation period is short, the terminal device may frequently perform PDCCH detection; if the set period of the activation period is long, the terminal device may not receive data in time.

No matter whether there is a PDCCH which needs to be received currently, the terminal device performs data detection in the active period, however, when there is no data to be received, the terminal device performs data detection, which may result in an increase in energy consumption of the terminal device.

In order to solve the above problems, the present application proposes the following technical idea: by sending the indication information to indicate whether the PDCCH needs to be received in the current activation period, the terminal equipment does not need to detect data in the activation period when no data needs to be received, so that the energy consumption of the terminal equipment is reduced.

Based on the above description, it is important how to determine whether to detect the PDCCH according to the first information, and the information processing method provided in the embodiment of the present application describes in detail an implementation manner of determining whether to detect the PDCCH, first, referring to fig. 3, where fig. 3 is a flowchart of the information processing method provided in an embodiment of the present application.

As shown in fig. 3, the method includes:

s301, receiving first information, wherein the first information is used for indicating whether a PDCCH to be received exists.

In this embodiment, the first information may be, for example, from a network device, or the first information may also be from another terminal device, which is not limited in this embodiment.

The first information may be used to indicate whether there is a PDCCH to be received, where the first information may indicate whether there is a PDCCH to be received in a current activation period, for example, the current activation period may be a next activation period corresponding to a time-frequency resource where the first information is located.

Alternatively, the first information may also indicate whether there is a PDCCH to be received in a certain activation period, and the like, which is not particularly limited in this embodiment.

The first information may be, for example, DCI information or may also be SIB information, and the embodiment does not limit an implementation manner of the first information as long as it can be used to indicate whether there is a PDCCH to be received currently.

In a possible implementation manner of this embodiment, the terminal device may receive the first information on the multi-beam resource, and then the terminal device may determine, according to a result of the demodulation of the first information, that the first information which is demodulated correctly is valid first information.

S302, whether the PDCCH is detected is determined according to the first information.

The terminal device may determine whether to detect the PDCCH on the corresponding resource according to the first information, and it may be understood that the terminal device may perform detection and reception on the first resource when receiving the PDCCH.

In a possible implementation manner, if the first information indicates that there is a PDCCH to be received, the terminal device performs detection and reception of the PDCCH on a time-frequency resource corresponding to the first information;

in another possible implementation manner, if the first information indicates that there is no PDCCH to be received, the terminal device does not perform PDCCH detection in an activation period corresponding to the first information.

How the first information specifically indicates may be determined by the network device according to whether there is a PDCCH that needs to be sent, and which activation period the first information specifically indicates, which may all be selected according to actual needs, which is not particularly limited in this embodiment.

The information processing method provided by the embodiment of the application comprises the following steps: receiving first information, wherein the first information is used for indicating whether a PDCCH to be received exists. And determining whether to detect the PDCCH according to the first information. Whether the PDCCH is detected or not is determined according to the indication of the first information, so that the data detection is not required in the activation period of the terminal equipment when no data needs to be received, and the energy consumption of the terminal equipment is effectively reduced.

Based on the foregoing embodiment, it can be understood that the terminal device may perform the detection of the PDCCH according to a preset period, and in a possible implementation manner, the terminal device may receive configuration information, where the configuration information may be used to indicate a first period and a first resource for receiving the PDCCH, that is, the terminal device may determine a location of an active period according to the first period, and determine, according to the first resource, at which time-frequency location of the active period the detection and the reception of the PDCCH are performed.

Next, a possible implementation manner of performing PDCCH detection by a terminal device is described with reference to fig. 4, where fig. 4 is a schematic diagram illustrating implementation of performing PDCCH detection by a terminal device according to an embodiment of the present disclosure.

Referring to fig. 4, assuming that the terminal device is currently configured with the active period and the inactive period shown in fig. 4, the terminal device may perform data detection in the active period, but the terminal device performs blind detection during data detection, and in order to instruct the terminal to receive, the network device may further send configuration information to the terminal device, and instruct, through the configuration information, the first resource for sending the PDCCH, so that the terminal device may perform blind detection only on the first resource.

For example, the first resource indicated by the configuration information includes a time domain resource and a frequency domain resource, in a possible implementation manner, an implementation manner of the first period may be as an active period and an inactive period shown in fig. 4, and a location of the first resource may be as shown in a gray part in fig. 4, and the terminal device detects the PDCCH at a time-frequency location corresponding to the first resource in the active period according to the configured first period.

Currently, if a PDCCH is detected, the terminal device may receive other data or perform a corresponding action command according to an indication of the PDCCH; if there is no PDCCH to receive, the terminal device also needs to detect the PDCCH according to the first resource indicated by the configuration information, and at this time, there is extra energy consumption.

Based on this, in this embodiment, first information for indicating a PDCCH to be received is proposed, so as to enable that when no data needs to be received, the terminal device does not need to perform data detection, two implementation manners of the first information are respectively described below with reference to fig. 5, where fig. 5 is an indication schematic diagram of the first information provided in the embodiment of the present application.

First, an implementation of the first information indicating that there is a PDCCH to be received is described with reference to fig. 5:

referring to fig. 5, assuming that the first information 1 indicates that there is a PDCCH to be received in the current active period, the terminal device detects the PDCCH on the first resource and receives the PDCCH.

Or, the first information may also indicate that a PDCCH to be received exists in the next active period, which is similar to that illustrated in fig. 5 and is not described herein again.

Next, an implementation manner in which the first information indicates that there is no PDCCH to be received is described with reference to fig. 5:

referring to fig. 5, if the first information 2 indicates that there is no PDCCH to be received in the current activation period, the terminal device does not perform PDCCH detection on the first resource, so that the energy consumption of the terminal device is effectively reduced on the basis of not missing data.

Or, the first information may also indicate that there is no PDCCH to be received in the next activation period, and the implementation manner of the first information is similar to that illustrated in fig. 5, which is not described herein again.

And, it may be determined in conjunction with fig. 5 that the length of the interval between the two configured first resources may be the first period.

In a possible implementation manner of the present application, in order to guarantee the validity of the indication of the first information, for example, a time range of the first information may be defined, for example, the first information may be received within a certain time range before the indication of the first resource, and the first information received within the time range may be determined to be valid first information, so that the validity of the indication of the first information may be guaranteed.

In another possible implementation manner of the present application, if a plurality of resources for receiving the first information exist before the first resource, the first information may be received on a resource most ahead in time; alternatively, the first information may be received on a resource that is the most recent resource, which is not particularly limited in this embodiment.

On the basis of the foregoing embodiments, in the method provided in the embodiments of the present application, the first information may also be used to indicate additional information to supplement the parameters of the PDCCH.

Currently, a terminal device may determine a time-frequency position for searching a PDCCH and related search parameters according to a control resource set (core) parameter and a search space (search space) parameter, however, based on these parameters, the terminal device still needs to perform certain parameter traversal blind test.

In order to further reduce the power consumption of the terminal device, in this embodiment, the first information may further indicate at least one of an aggregation level, a CCE sequence number, a beam parameter, and a time-frequency resource parameter of the PDCCH, so as to help the terminal device receive data and reduce a blind detection range.

In one possible implementation, the first information may explicitly indicate at least one of an aggregation level, a control channel element sequence number, a beam parameter, and a time-frequency resource parameter of the PDCCH.

For example, the first information may carry additional information for indicating at least one of an aggregation level, a control channel element sequence number, a beam parameter, and a time-frequency resource parameter of the PDCCH.

The parameters of the PDCCH are supplemented through the first information, so that the terminal equipment can receive the PDCCH according to the configuration parameters of the PDCCH and the supplementary parameters of the first information to assist the terminal equipment in receiving and demodulating the PDCCH, and the complexity of the terminal equipment for receiving the PDCCH is further reduced, so that the power consumption is reduced.

In another possible implementation manner, the first information may also implicitly indicate a time-frequency resource of the PDCCH, for example, the terminal device may receive parameters of the demodulated first information, where the receive parameters of the first information include at least one of an aggregation level, a CCE sequence number, a beam parameter, and a time-frequency resource parameter of the PDCCH.

The parameter of the PDCCH may be obtained according to the received parameter of the first information through a preset corresponding relationship, where the corresponding relationship may be, for example, an equality relationship, or a sequence number relationship.

The parameters indicated by the first information described above may be indicated in an implicit manner, for example, that is, when the terminal device receives the PDCCH, some or all of the parameters obtained when the terminal device receives the first information may be directly used.

For example, if the aggregation level used by the first information is 4, when detecting the PDCCH, the PDCCH may also be detected by using the aggregation level 4; for another example, if the beam used for the first information is ID1, the PDCCH is also demodulated using the beam ID 1; for another example, if the first information uses the first set of candidate parameters, the PDCCH may also be detected using the first set of parameters in the corresponding configuration during demodulation.

The terminal equipment can be informed of the rule using the corresponding parameter in a preset mode; or the terminal device may also be notified by means of sending configuration information.

On the basis of the foregoing embodiment, the first information may be used to indicate states or parameters of multiple carriers, for example, if N carriers currently exist, where N is an integer greater than or equal to 1, the first information may indicate states or parameters of all carriers or some carriers in the N carriers.

Wherein the terminal device may correspond the carrier to the indication of the first information one by one according to the configuration information of the carrier, and in a possible implementation manner, the corresponding manner may be all corresponding, that is, the carrier parameters in the first information correspond to the carrier configured by the terminal device in sequence,

in another possible implementation manner, the corresponding manner may also be partial correspondence, that is, the carrier parameter value in the first information includes a parameter of a partially activated carrier, and the terminal device may correspond the carrier parameter in the first information to each carrier according to the activation state of the carrier.

How to set each carrier parameter may be selected according to actual requirements, which is not particularly limited in this embodiment.

On the basis of the above embodiment, it can be understood that the first information and the like may be from a network device, or may be from other terminals or control devices, so that an information processing method executed by the network device side is described below with reference to fig. 6, where fig. 6 is a flowchart of an information processing method provided in another embodiment of the present application.

As shown in fig. 6, the method includes:

s601, detecting whether a PDCCH to be sent to one or more terminal devices exists.

The network device detects whether there is a PDCCH that needs to be sent to one or more terminal devices currently, and determines a detection result, where the detection result may be that there is a PDCCH to be sent to one or more terminal devices, or that there is no PDCCH to be sent.

In a possible implementation manner, the network device sends the PDCCH through the terminal device on the first resource, so that the network device can detect whether the PDCCH to be sent exists on the first resource.

S602, according to the detection result, first information is sent, wherein the first information is used for indicating whether a PDCCH to be sent exists.

The network device sends first information to the terminal device according to the determined detection result, and in a possible implementation manner, if the detection result indicates that there is no PDCCH to be sent, the first information is used for indicating that there is no PDCCH to be sent; in another possible implementation manner, if the detection result indicates that there is a PDCCH to be sent, the first information is used to indicate that there is a PDCCH to be sent.

On the network equipment side, the first information is used for indicating whether a PDCCH to be sent exists.

And sending first information according to the detection result, wherein the first information is used for indicating whether the PDCCH to be sent exists.
