Description

Communication method, communication apparatus, and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication method, a communication apparatus, and a storage medium.

Background

In Long Term Evolution (LTE), when a terminal device is in a Radio Resource Control (RRC) connected state, a Discontinuous Reception (DRX) mechanism is defined to save unnecessary power consumption of the terminal device. The basic principle of the DRX mechanism is: packet-based data streams are typically bursty. There is a data stream transmitted for a period of time, but no data stream is transmitted for a subsequent longer period of time. When no data stream is transmitted, the power consumption can be reduced by stopping receiving a Physical Downlink Control Channel (PDCCH), so as to improve the battery standby time of the terminal device.

In the first release of 5G New Radio access (NR), the DRX mechanism of LTE is used. Although the DRX mechanism can save the power consumption of the terminal device, the current DRX mechanism is not flexible in configuration and cannot dynamically adjust the sleep time of the terminal device according to the arrival interval of the data packets of the terminal device which are not used for service. Therefore, in the second version of NR, in order to further save the power consumption of the terminal device, the DRX mechanism of the terminal device in the RRC connected state needs to be enhanced.

After the terminal device enables the DRX mechanism and configuration, there is still a case that when the terminal device wakes up to monitor the PDCCH during the DRX on duration timer (DRX OnDurationTimer) operation of some DRX cycles or during the DRX inactivity timer (DRX-inactivity timer) operation, the terminal device cannot monitor any of its own PDCCHs because no data arrives or the network device does not schedule the terminal device. In this case, the terminal device wakes up to monitor the PDCCH during the DRX on duration timer running or during the DRX inactivity timer running, causing extra power consumption. To address this problem, one current solution is: if the network device does not schedule uplink and downlink data transmission of the terminal device during the operation of the DRX on duration timer of the terminal device or during the operation of the DRX inactive timer, the network device sends an indication message to the terminal device to notify the terminal device that the terminal device does not need to wake up to monitor the PDCCH in some time periods. This indication information may be referred to as a "Go to Sleep" indication.

One way to send the above-mentioned "Go to Sleep" indication is to transmit through Downlink Control Information (DCI). This means that when monitoring the PDCCH, the terminal device needs to perform blind detection on the new DCI in addition to the existing DCI in the PDCCH, and if the new DCI is different from any existing DCI in length, the number of blind detection times of the terminal device is increased, thereby increasing the power consumption of the terminal device.

Detailed Description

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system includes a network device and at least one terminal device. The terminal device is located in a coverage area of the network device and communicates with the network device to implement the following technical solutions provided by the embodiments of the present application.

The embodiments of the present application have been described with reference to a network device and a terminal device, where the network device and the terminal device may operate in a licensed frequency band or an unlicensed frequency band, where:

a Network device, also called a Radio Access Network (RAN) device, is a device for accessing a terminal device to a wireless Network, and may be an evolved Node B (eNB or eNodeB) in LTE, or a relay station or an Access Point, or a base station in a 5G Network, such as a Transmission and Reception Point (TRP), a controller, and is not limited herein. In one possible approach, the network device may be a base station of a CU and DU separation architecture (e.g., a gNB).

The terminal device may be a wireless terminal device or a wired terminal device. The wireless terminal device can refer to a device with wireless transceiving function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self driving (self driving), a wireless terminal device in remote medical treatment (remote medical), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), and the like, which are not limited herein. It can be understood that, in the embodiment of the present application, the terminal device may also be referred to as a User Equipment (UE).

Figure 2 is a diagram of the DRX cycle involved in the DRX mechanism. Note that the DRX cycle shown in fig. 2 is a DRX cycle used when the terminal device is in an RRC connected state. Referring to fig. 2, one DRX cycle includes two parts: a first part identified as "On Duration (On Duration)" and a second part identifying "DRX Opportunity (DRX)". In the opening duration, the terminal equipment monitors the PDCCH, and the opening duration is controlled by a DRX opening duration timer (DRX-OnDurationTimer); during the DRX opportunity time, the terminal device does not monitor the PDCCH to reduce power consumption. Each time the terminal device is scheduled to initially transmit a new data, the terminal device may start or restart a DRX inactivity timer (DRX-inactivity timer), and then the terminal device will remain in an active state until the DRX inactivity timer expires. The DRX inactivity timer specifies the length of time that the terminal device is in the active state for when it successfully decodes a PDCCH that schedules new data initial transmission. It can be seen from this figure that the longer the duration of the second part, the lower the power consumption of the terminal device.

After the terminal device starts the DRX mechanism and configuration, when no data is transmitted, the terminal device can reduce power consumption by stopping receiving the PDCCH, so that the battery standby time of the terminal device is prolonged. In order to avoid extra power consumption caused by the fact that the terminal device wakes up to monitor the PDCCH during the On Duration when no data arrives or the network device does not schedule the terminal device, the prior art sends a "Go to Sleep" indication to the terminal device through the network device, and informs the terminal device that it is not necessary to wake up to monitor the PDCCH during the On Duration. However, the indication of "Go to Sleep" needs to be transmitted through DCI, which means that when the terminal device monitors the PDCCH during the On Duration, the terminal device needs to blindly detect the existing DCI in the PDCCH, and also needs to blindly detect the new DCI.

Based On the above technical problem, embodiments of the present application provide a communication method, apparatus, and storage medium to reduce the number of blind detections while reducing the extra power consumption caused by the terminal device waking up to monitor the PDCCH at the On Duration.

Fig. 3 is a signaling diagram of a communication method according to an embodiment of the present application. The embodiment provides a communication method, and the method of the embodiment can be applied to terminal equipment and network equipment. As shown in fig. 3, the method of the present embodiment includes:

s301, the network device generates DCI.

The first indication information and the information set are included in the DCI. The first indication information is used for indicating that the information set comprises scheduling information of a physical shared channel; or, the first indication information is used for indicating that the information set includes PDCCH monitoring information. Further, the PDCCH monitoring information includes time length information, and the PDCCH monitoring information is used to instruct the terminal device to stop monitoring the PDCCH in the time period indicated by the time length information.

In this step, the scheduling information of the physical shared channel, that is, the DCI in the prior art includes information for scheduling the shared channel, for example, information such as time domain resource allocation, frequency domain resource allocation, Modulation and Coding Scheme (MCS), power control, and the like. The Physical Shared Channel may include at least one of a Physical Downlink Shared Channel (PDSCH) and a Physical Uplink Shared Channel (PUSCH).

The method comprises the steps of defining new DCI, enabling the DCI to comprise first indication information and an information set, wherein the information set comprises one of scheduling information and PDCCH monitoring information of a physical shared channel, and indicating whether the scheduling information or the PDCCH monitoring information of the physical shared channel is comprised in the information set through the first indication information. For the terminal device supporting the DCI, only the DCI with the same length as the new DCI may be monitored, so that the number of blind tests of the terminal device may be avoided from being increased, and the purpose of reducing the power consumption of the terminal device may be achieved.

In one implementation, the newly defined DCI includes 1 bit (bit) of first indication information, which is used to indicate whether the information set includes PDCCH monitoring information or scheduling information of a physical shared channel. For example, when the bit value is 0, the indication information set includes PDCCH monitoring information; when the bit value is 1, the indication information set includes scheduling information of a physical shared channel, and in this case, the remaining information included in the newly defined DCI is the same as the information included in the existing DCI 1_0 or DCI 1_ 1.

In another implementation, the newly defined DCI includes 1 bit (bit) of first indication information, which is used to indicate whether the information set includes PDCCH monitoring information or scheduling information of a physical shared channel. For example, when the bit value is 0, the indication information set includes PDCCH monitoring information; when the bit value is 1, the indication information set includes scheduling information of a physical shared channel, and in this case, the remaining information included in the newly defined DCI is the same as the information included in the existing DCI 0_0 or DCI 0_ 1.

The term "generating" in this step may be understood as "obtaining" or other terms of similar meaning.

S302, the network equipment sends the DCI to the terminal equipment.

Correspondingly, the terminal equipment receives the DCI.

And S303, when the information set comprises the PDCCH monitoring information, the terminal equipment stops monitoring the PDCCH in the time period indicated by the time length information.

After receiving the DCI, the terminal device parses the DCI to obtain the first indication information and/or information set included in the DCI. For the terminal device to determine whether the PDCCH monitoring information or the scheduling information of the physical shared channel is included in the information set, the method may be implemented by any one of the following implementation manners:

in one implementation, the terminal device obtains the first indication information, and through the first indication information, the terminal device may determine that the information set includes PDCCH monitoring information or scheduling information of a physical shared channel. Further, when the PDCCH monitoring information is included in the information set, the terminal device stops monitoring the PDCCH for the time period indicated by the time length information.

In another implementation manner, the terminal device obtains the information set, and determines that the information set includes PDCCH monitoring information or scheduling information of a physical shared channel according to specific content included in the information set. And further, when the information set comprises the PDCCH monitoring information, the terminal equipment stops monitoring the PDCCH within the time period indicated by the time length information.

In another implementation manner, the terminal device obtains the information set and the first indication information, and determines that the information set includes PDCCH monitoring information or scheduling information of a physical shared channel through the information set and the first indication information. And further, when the information set comprises the PDCCH monitoring information, the terminal equipment stops monitoring the PDCCH within the time period indicated by the time length information.

If the information set includes scheduling information of a physical shared channel, the terminal device processes the scheduling information according to a manner in the prior art, including at least one of:

when the information set comprises the scheduling information of the PDSCH, receiving downlink data;

when the information set comprises the scheduling information of the PUSCH, sending uplink data;

and when the scheduling information is used for scheduling new data transmission, starting a DRX (discontinuous reception) inactive timer, and monitoring a PDCCH (physical downlink control channel) during the operation of the DRX inactive timer.

If the information set comprises the PDCCH monitoring information, the terminal equipment stops monitoring the PDCCH within the time period indicated by the time length information in the PDCCH monitoring information. The method can be realized through any one of the following implementation modes:

in one implementation, the unit of the period indicated in the time length information is a DRX cycle. And after receiving the PDCCH monitoring information, the terminal equipment does not monitor the PDCCH within the opening duration of the n DRX periods indicated by the time length information. Wherein n is a positive integer greater than or equal to 1. And after the n DRX periods, the terminal equipment resumes monitoring the PDCCH in the starting duration of the DRX periods. Further, the terminal device does not monitor the PDCCH for the on duration of the n DRX cycles, including: the terminal device does not run the DRX on duration timer for the n DRX cycles. Further, after receiving the DCI containing the PDCCH monitoring information, the terminal device does not run the DRX inactivity timer, that is: when the terminal equipment receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is not operated, the terminal equipment does not start the DRX inactivity timer; or, when the terminal device receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is running, the terminal device stops the DRX inactivity timer.

In another implementation, the unit of the time period indicated in the time length information is a time unit, and the time unit includes, but is not limited to, a millisecond, a slot (slot), a mini-slot (mini-slot), an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a PDCCH monitoring period, and the like. And after receiving the PDCCH monitoring information, the terminal equipment does not monitor the PDCCH in the n time units indicated by the time length information. Wherein n is a positive integer greater than or equal to 1. After the n DRX cycles, the terminal device resumes normal operation under the DRX mechanism, i.e. if the activation time condition defined in the prior art is met, the terminal device monitors the PDCCH, otherwise, the terminal device does not monitor the PDCCH. Further, after receiving the DCI containing the PDCCH monitoring information, the terminal device does not run the DRX on duration timer, that is: when the terminal equipment receives the DCI containing the PDCCH monitoring information, if the DRX starting duration timer does not run, the terminal equipment does not start the DRX starting duration timer; or, when the terminal device receives the DCI containing the PDCCH monitoring information, if the DRX on-duration timer is running, the terminal device stops the DRX on-duration timer. Further, after receiving the DCI containing the PDCCH monitoring information, the terminal device does not run the DRX inactivity timer, that is: when the terminal equipment receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is not operated, the terminal equipment does not start the DRX inactivity timer; or, when the terminal device receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is running, the terminal device stops the DRX inactivity timer.

Optionally, in any implementation manner described above, when the information set includes scheduling information of a physical shared channel, the terminal device only monitors other PDCCHs that are different from the above PDCCH, that is, an existing PDCCH, during a next On Duration period or an Active time (Active time).

In the embodiment of the application, a terminal device receives DCI sent by a network device, where the DCI includes first indication information and an information set, where the first indication information is used to indicate that the information set includes scheduling information of a physical shared channel, or is used to indicate that the information set includes PDCCH monitoring information, where the PDCCH monitoring information includes time length information, and the PDCCH monitoring information is used to indicate the terminal device to stop monitoring a PDCCH; and when the PDCCH monitoring information is included in the information set, the terminal equipment stops monitoring the PDCCH within the time period indicated by the time length information. In the embodiment of the present application, for the terminal device supporting the DCI, only the DCI with the same length as the new DCI may be monitored, so that the increase of the blind detection times of the terminal device may be avoided, and the purpose of reducing the power consumption of the terminal device is achieved.

On the basis of the foregoing embodiment, further, the DCI or the PDCCH carrying the DCI may be scrambled by the first identifier. The first Identifier may be a Cell Radio Network Temporary Identifier (C-RNTI) or a Configured scheduling Radio Network Temporary Identifier (CS-RNTI) defined in an existing standard.

Alternatively, the DCI or the PDCCH carrying the DCI may be scrambled by a second identifier. The second identifier is configured for the terminal device by the network device through the radio resource reconfiguration message. The second Identifier is a newly defined Radio Network Temporary Identifier (RNTI), and the second Identifier may specifically be a Radio Network Temporary Identifier used for scheduling unicast transmission and/or PDCCH monitoring information. Specifically, the second identifier may be used to scramble a radio network temporary identifier of DCI carrying scheduling unicast transmission information and/or PDCCH monitoring information, where unicast transmission refers to data transmission for a single terminal device.

When the DCI or the PDCCH carrying the DCI may be scrambled by the second identifier, the receiving of the DCI by the terminal device may be implemented by any one of the following implementation manners:

in a first implementation manner, the receiving, by a terminal device, DCI may include: the terminal device monitors the PDCCH scrambled by the second identifier only at the first PDCCH opportunity (i.e. PDCCH occasion) of the On Duration (i.e. On Duration) of the DRX period, and the PDCCH scrambled by the second identifier is used for carrying the DCI.

In this implementation, considering that DCI including PDCCH monitoring information is transmitted only in the first PDCCH occase of the On Duration, the terminal device only monitors the PDCCH scrambled by the second identifier in the first PDCCH occase of the On Duration of the DRX cycle. In addition, as in the prior art, the terminal device also monitors the PDCCH scrambled by another identifier in the first PDCCH occase of the On Duration of the DRX cycle, where the other identifier is the existing RNTI and the other identifier is different from the second identifier. That is, in the first PDCCH occase of the On Duration of the DRX cycle, the terminal device monitors not only the PDCCH scrambled by the second identity but also the PDCCH scrambled by other identities.

In a second implementation manner, the receiving, by the terminal device, the DCI may include: and the terminal equipment monitors the PDCCH scrambled by the second identifier in the activation time of the DRX period, wherein the PDCCH scrambled by the second identifier is used for carrying the DCI. Wherein the active time is the active time defined by the existing standard, and includes the time when the DRX on duration timer runs, the time when the DRX off timer runs, and the like.

Specifically, during the active time of the DRX cycle, the terminal device monitors not only the PDCCH scrambled by the second identity but also the PDCCH scrambled by other identities. The related description of other identifiers is the same as that of the first implementation manner, and is not described herein again.

Fig. 4 is a signaling diagram of a communication method according to another embodiment of the present application. The embodiment provides a communication method, and the method of the embodiment can be applied to terminal equipment and network equipment. As shown in fig. 4, on the basis of the step shown in fig. 3, before S302, the network device sends DCI to the terminal device, the communication method of this embodiment may further include:

s401, the network equipment sends second indication information to the terminal equipment.

And the second indication information is used for indicating the terminal equipment to receive the DCI.

Correspondingly, before the terminal device receives the DCI, the terminal device receives second indication information sent by the network device.

Before receiving the second indication information, the terminal equipment only receives DCI defined in the prior art, namely DCI 0_0, DCI 0_1, DCI 1_0 and DCI 1_1, for DCI which is scrambled by C-RNTI or CS-RNTI and is used for scheduling physical shared channels. After receiving the second indication information, the terminal equipment receives the DCI containing the first indication information and the information set, and does not receive DCI 0_0, DCI 0_1, DCI 1_0 and DCI 1_1 which are scrambled by C-RNTI or CS-RNTI and are used for scheduling physical shared channels.

In addition, the embodiment of the present application does not limit the execution order of S301 and S401, and both may be executed simultaneously or sequentially, for example, S301 is executed first and then S401 is executed, or S401 is executed first and then S301 is executed.

In distinction from the above-described embodiments, the present application also provides the following embodiments for solving the above-described technical problems. It is to be understood that the following embodiments are independent of the above embodiments.

Fig. 5 is a signaling diagram of a communication method according to another embodiment of the present application. The embodiment provides a communication method, and the method of the embodiment can be applied to terminal equipment and network equipment. As shown in fig. 5, the method of the present embodiment includes:

s501, the network equipment generates DCI.

Wherein, the DCI includes PDCCH monitoring information. The PDCCH monitoring information includes time length information. And, the PDCCH monitoring information is used to instruct the terminal device to stop monitoring the PDCCH.

By multiplexing the DCI in the prior art, the PDCCH monitoring information is included in the DCI. Because the PDCCH monitoring information in the embodiment of the application is multiplexed with the existing DCI, compared with the prior art, the blind detection times of the terminal equipment can be reduced, and the power consumption of the terminal equipment is reduced.

For example, the DCI may be DCI 1_0 or DCI 1_ 1.

For another example, the DCI may be DCI 0_0 or DCI 0_ 1.

S502, the network equipment sends the DCI to the terminal equipment.

Correspondingly, the terminal equipment receives the DCI.

S503, the terminal equipment determines that the DCI comprises PDCCH monitoring information according to the first information.

The first information is a terminal device identifier or information meeting a preset condition. The terminal equipment identifier is a wireless network temporary identifier used for scheduling PDCCH monitoring information.

Optionally, if the first information is a terminal device identifier, the DCI or the PDCCH carrying the DCI is scrambled by the terminal device identifier; the terminal equipment identification is configured for the terminal equipment by the network equipment through a wireless resource reconfiguration message. The terminal device identifier is a newly defined RNTI, and the terminal device identifier may specifically be a radio network temporary identifier used for scheduling PDCCH monitoring information. This terminal equipment identity may for example be referred to as a Power Saving radio network temporary identity (Power Saving RNTI, PS-RNTI). The terminal device identifier may be unique to a single terminal device, or may be shared by a plurality of terminal devices.

Optionally, if the first information is information that satisfies a predetermined condition, the first information may be included in the DCI. The preset condition can be any one of the following conditions:

condition 1: the DCI comprises a Frequency domain resource allocation (Frequency domain resource allocation) field and a Time domain resource allocation (Time domain resource allocation) field, wherein the values of the Frequency domain resource allocation field are all 1, and the values of the Time domain resource allocation field are all 1;

For example, when the first information is information satisfying a preset condition, the DCI or the PDCCH carrying the DCI may be scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) or a Configured scheduling Radio Network Temporary Identifier (CS-RNTI). Optionally, when the DCI or the PDCCH carrying the DCI is scrambled by a C-RNTI or a CS-RNTI and any one of the above conditions is satisfied, the terminal device determines that the DCI includes PDCCH monitoring information.

And S504, the terminal equipment stops monitoring the PDCCH in the time period indicated by the time length information.

In the embodiment of the application, the terminal device receives DCI sent by the network device, where the DCI includes PDCCH monitoring information, the PDCCH monitoring information includes time length information, and the PDCCH monitoring information is used to instruct the terminal device to stop monitoring the PDCCH, and then the terminal device determines that the DCI includes the PDCCH monitoring information according to the first information, and stops monitoring the PDCCH in a time period indicated by the time length information. The method can be realized through any one of the following implementation modes:

In another implementation, the unit of the time period indicated in the time length information is a time unit, and the time unit includes, but is not limited to, a millisecond, a slot (slot), a mini-slot (mini-slot), an OFDM symbol, a PDCCH monitoring period, and the like. And after receiving the PDCCH monitoring information, the terminal equipment does not monitor the PDCCH in the n time units indicated by the time length information. Wherein n is a positive integer greater than or equal to 1. After the n DRX cycles, the terminal device resumes normal operation under the DRX mechanism, i.e. if the activation time condition defined in the prior art is met, the terminal device monitors the PDCCH, otherwise, the terminal device does not monitor the PDCCH. Further, after receiving the DCI containing the PDCCH monitoring information, the terminal device does not run the DRX on duration timer, that is: when the terminal equipment receives the DCI containing the PDCCH monitoring information, if the DRX starting duration timer does not run, the terminal equipment does not start the DRX starting duration timer; or, when the terminal device receives the DCI containing the PDCCH monitoring information, if the DRX on-duration timer is running, the terminal device stops the DRX on-duration timer. Further, after receiving the DCI containing the PDCCH monitoring information, the terminal device does not run the DRX inactivity timer, that is: when the terminal equipment receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is not operated, the terminal equipment does not start the DRX inactivity timer; or, when the terminal device receives the DCI containing the PDCCH monitoring information, if the DRX inactivity timer is running, the terminal device stops the DRX inactivity timer.

In the embodiment of the application, the PDCCH monitoring information multiplexes the existing DCI and keeps the same length with the existing DCI, so that compared with the prior art, the blind detection times of the terminal equipment can be reduced, and the power consumption of the terminal equipment is reduced.

Further, the receiving, by the terminal device, the DCI may include: the terminal device monitors the PDCCH transmitting the DCI only at the first PDCCH occasion (i.e., PDCCH occasion) of the On Duration (i.e., On Duration) of the DRX cycle. In this implementation, considering that DCI including PDCCH monitoring information is transmitted only On the first PDCCH occase of the On Duration, the terminal device only monitors the PDCCH scrambled by the terminal device identifier On the first PDCCH occase of the On Duration of the DRX cycle. In addition, as in the prior art, the terminal device also monitors the PDCCH scrambled by another identifier in the first PDCCH occase of the On Duration of the DRX cycle, where the other identifier is the existing RNTI and the other identifier is different from the terminal device identifier. That is, in the first PDCCH occase of the On Duration of the DRX cycle, the terminal device monitors not only the PDCCH scrambled by the terminal device identity but also the PDCCH scrambled by other identities.

Optionally, as a supplement, if the terminal device does not monitor the PDCCH scrambled by the terminal device identity in the first PDCCH occast of the On Duration of the DRX cycle, the terminal device only monitors other PDCCHs different from the above PDCCH, that is, the PDCCH scrambled by the existing RNTI, during the next On Duration or Active time (Active time).

Alternatively, the receiving, by the terminal device, the DCI may include: and the terminal equipment monitors the PDCCH scrambled by the terminal equipment identification in the activation time of the DRX period, wherein the PDCCH scrambled by the terminal equipment identification is used for bearing the DCI. Specifically, during the active time of the DRX cycle, the terminal device monitors not only the PDCCH scrambled by the terminal device identifier described above, but also the PDCCH scrambled by other identifiers. The relevant description of other identifiers is the same as above, and the description is omitted here.
