Description

Communication method and equipment

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on September 5, 2018, with application number 201811033282.X, and with the application name "a communication method and device", the entire contents of which are incorporated herein by reference. in.

Technical field

The present application relates to the field of communications, and in particular, to a communication method and device.

Background technique

In the wireless communication system, in order to save the power consumption of the terminal equipment on the premise of ensuring that data can be effectively transmitted, a discontinuous reception (DRX) mechanism is introduced. When there is no DRX mechanism, the terminal device will always monitor the downlink physical downlink control channel (PDCCH) subframe to check whether there is information from the serving cell. However, many times in practice, terminal equipment does not always perform effective information interaction with the network. Therefore, if the terminal equipment continues to monitor the PDCCH, it is costly. Conversely, when DRX is configured, the terminal device can periodically enter the sleep mode (sleep mode) at certain times. The terminal device does not need to continuously monitor the PDCCH, but wakes up from the sleep state when it needs to monitor (wake up). ), So that the terminal device can achieve the purpose of power saving. Although this has a certain impact on the time delay of data transmission, if this time delay does not affect the user experience, then considering the power consumption of the terminal device, it is meaningful to perform DRX. The DRX cycle configuration includes two time periods. The time period marked "OnDuration" is the time when the terminal device monitors the PDCCH and the terminal device is in the awake state; the time period marked "Opportunity for DRX" is the DRX sleep time, that is, the When the power is not monitored, the terminal device is in a sleep state.

Carrier aggregation (CA) is a technology that increases transmission bandwidth to meet the single user peak rate and system capacity requirements. The CA technology can aggregate two or more component carriers (CCs) together to achieve a larger transmission bandwidth and effectively improve the uplink and downlink transmission rates. The terminal device decides that it can use several carriers for uplink and downlink transmission at the same time according to its own capacity. A primary cell (PCell) is a cell where a terminal device establishes an initial connection, or a cell which performs RRC connection reconstruction, or a primary cell designated during a handover process. The PCell is responsible for radio resource control (radio resource control, RRC) communication with the terminal device. The CC corresponding to the PCell is called a primary component carrier (PCC); a secondary cell (SCell) is added through RRC connection reconfiguration after the initial security activation process, and is used to provide additional wireless resources. The CC corresponding to the SCell is called a secondary component carrier (SCC).

Considering the case of CA, when the terminal device is configured with DRX, if the terminal device does not need to send or receive data within a certain period of time, the base station can send a go-to-sleep (GTS) signal, In order to change the relevant durations (OnDuration) of the terminal equipment on the PCell and SCell, reduce the PDCCH monitoring of the terminal equipment, and achieve the purpose of energy saving. Scenario 1: The GTS signal is sent before the “OnDuration” time period, and the upcoming “OnDuration” time period of the terminal device on the PCell and SCell will transition to the sleep state without waking the terminal device. When the next DRX cycle arrives, the DRX operation of the terminal device in PCell and SCell returns to normal. Scenario 2: The GTS signal is sent during the “OnDuration” time period, and the “OnDuration” time period that the terminal device is performing on the PCell and SCell will immediately transition to the sleep state. When the next DRX cycle arrives, the DRX operation of the terminal device in PCell and SCell returns to normal.

It can be seen from the above that after the terminal device receives the GTS signal, the state of only one “OnDuration” time period on PCell and SCell changes, and when the next DRX cycle arrives, the normal “On” on PCell and SCell will resume. Duration "period. Therefore, the power consumption of the terminal equipment is still large.

Summary of the Invention

The embodiments of the present application provide a communication method and device, which can further save power consumption of a terminal device on the premise of ensuring that data can be effectively transmitted.

In a first aspect, a communication method is provided. The terminal device receives the GTS signal in the first DRX cycle; the terminal device responds to the GTS signal, performs the DRX operation on the primary cell using the first configuration parameter set, and performs the DRX operation on the secondary cell using the second configuration parameter set; The length of the DRX duration timer in the first DRX configuration parameter set is different from the length of the DRX duration timer in the second DRX configuration parameter set.

In the embodiment of the present application, after the terminal device receives the GTS signal, a DRX parameter configuration different from the primary cell is used on the secondary cell, for example, the length of the DRX duration timer on the secondary cell is shortened (that is, the “On Duration” duration). First, because the secondary cell uses a short "OnDuration" DRX configuration, this operation can reduce the PDCCH monitoring of the terminal device on the secondary cell and reduce the power consumption of the terminal device. In addition, the network device can flexibly control the number of serving cells that perform service transmission for the terminal device by adjusting the time for issuing the PDCCH scheduling information. For example, when only the primary cell can meet the service transmission requirements of the terminal device, the network device may choose to send the moment when the "OnDuration" on the secondary cell ends but the primary cell is still in the "OnDuration" state within a DRX cycle. PDCCH scheduling information, so that only the primary cell can be used for data transmission. Similarly, when the primary cell and one or more secondary cells are required to perform data transmission at the same time, the network device may choose to send the PDCCH scheduling information at a time when both the secondary cell and the primary cell are in the “OnDuration” state within one DRX cycle. This operation can adjust the number of serving cells according to the amount of traffic, thereby avoiding unnecessary overhead.

According to this embodiment, a certain period of time is set for the secondary cell.

The network device may be a device for communicating with the terminal device, for example, it may be a base station (Base Transceiver Station, BTS) in the GSM system or CDMA, or a base station (NodeB, NB) in the WCDMA system, or it may be Evolutionary NodeB (eNB or eNodeB) in the LTE system, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, and a network-side device in a future 5G network or a network after 5G or Network equipment in future evolved PLMN networks.

The network device involved in the embodiment of the present invention may also be referred to as a Radio Access Network (RAN) device. The RAN device is connected to the terminal device, and is used to receive data from the terminal device and send it to the core network device. RAN devices correspond to different devices in different communication systems, for example, base stations and base station controllers in 2G systems, base stations and radio network controllers (RNCs) in 3G systems, and evolution in 4G systems. The base station (Evolutionary NodeB, eNB) corresponds to the 5G system in the 5G system, such as the access network equipment (for example, gNB, CU, DU) in the New Radio Access System (NR).

In order to facilitate the understanding of this application, first introduce several elements that will be introduced in the description of this application:

In the active state or the awake state, the terminal device monitors the PDCCH.

In the sleep state, the terminal device does not monitor the PDCCH.

In the deactivated state, after the serving cell of the terminal device is deactivated, the terminal device does not perform uplink control, data, and random access transmission in the serving cell, and does not perform downlink control monitoring (ie, PDCCH monitoring) in the serving cell.

In wireless communication systems, in order to save the power consumption of terminal equipment on the premise of ensuring that data can be effectively transmitted, a DRX mechanism is introduced.

FIG. 1 is a schematic diagram of a DRX cycle configuration based on an embodiment of the present application. The time period identified as "Duration" is the time during which the terminal device monitors the PDCCH, and the terminal device is in the awake state. The time period identified as "Opportunity for DRX" is the DRX sleep time, that is, the time when the terminal device does not listen to the PDCCH in order to save power, and the terminal device is in the sleep state. The DRX mechanism has two types of cycle configuration: long cycle and short cycle. The short cycle is optional parameter configuration. The terminal device can be configured with a DRX long period and a DRX short period at the same time. In this configuration, the long period is usually configured as an integer multiple of the short period.

FIG. 2 is a schematic diagram of a typical DRX working mode based on an embodiment of the present application. When DRX is configured, the terminal device first enters OnDuration when each DRX cycle arrives, and starts the DRX duration timer (drx-onDurationTimer). During OnDuration, the terminal device continuously monitors the PDCCH: if no PDCCH scheduling information is received during this period of time, after the DRX duration timer expires, the terminal device will enter the sleep state and stop monitoring the PDCCH; if during this time After receiving the PDCCH scheduling information, the DRX inactivity timer (drx-InactivityTimer) is started or restarted immediately. When the DRX inactivity timer is running, the terminal device must keep monitoring the PDCCH.

In addition, if there is uplink or downlink data that needs to be retransmitted, a DRX downlink retransmission timer (drx-RetransmissionTimerDL) and a DRX uplink retransmission timer (drx-RetransmissionTimerUL) will be started. These two timers are for each mixed An automatic repeat request (hybrid, automatic, repeat, request, HARQ) process configuration is the maximum time a terminal device waits for a retransmission operation.

When the DRX inactivity timer expires and the DRX downlink or uplink retransmission timers are not running, or when the terminal device receives the DRX command media access control (MAC) control element (CE), the terminal device enters Sleep mode. If the DRX short cycle is configured, the DRX short cycle is used, and the DRX short cycle timer (drx-ShortCycleTimer) is started or restarted at the same time; otherwise, the DRX long cycle is used.

When the DRX short period timer expires, or when a long DRX command MAC CE is received, the terminal device uses the DRX long period.

FIG. 3 is a schematic diagram of a CA type provided by an embodiment of the present application. CA types include three types: intra-band aggregation for continuous CCs, intra-band aggregation for non-continuous CCs, and inter-band aggregation.

The primary cell PCell is a cell where the terminal device performs initial connection establishment, or a cell where RRC connection is reestablished, or a primary cell designated during the handover process. PCell is responsible for RRC communication with the terminal equipment. The CC corresponding to PCell is called PCC; the secondary cell SCell is added through RRC connection reconfiguration after the initial security activation process, and is used to provide additional wireless resources. The CC corresponding to the SCell is called an SCC.

Generally, a terminal device configured with a CA can be connected to one PCell and a maximum of 31 SCells. These cells constitute a serving cell set of the terminal device, and the serving cell set includes a maximum of 32 serving cells. CA is a terminal-level feature. Different terminal devices may have different PCell, SCell, and serving cell sets. The same cell may be a PCell for a certain terminal device, but may be an SCell for another terminal device.

Considering the case of CA, when the terminal equipment is configured with DRX, if the terminal equipment does not need to send or receive data within a certain period of time, the base station can send a GTS signal to PCell to change the terminal equipment on PCell and SCell The related OnDuration reduces the PDCCH monitoring of the terminal device and achieves the purpose of energy saving. Generally, when a terminal device receives a GTS signal, the following processing methods can be adopted.

Scenario 1: GTS signal is sent before OnDuration

FIG. 4 is a schematic diagram of a general processing method of a terminal device when a GTS signal is transmitted before OnDuration. As shown in Figure 4, when the terminal device does not need to perform information interaction with the network device for a period of time, the network device can send a GTS signal before the arrival of an OnDuration, and then the forthcoming of the terminal device on PCell and SCell OnDuration will transition to sleep without waking the end device. When the next DRX cycle arrives, the DRX operation of the terminal device in PCell and SCell returns to normal.

Scenario 2: GTS signal is sent during On Duration

FIG. 5 is a schematic diagram of a general processing method of a terminal device when a GTS signal is transmitted during an OnDuration. As shown in Figure 5, when a terminal device has no data to send or receive during an OnDuration period, the network device can send a GTS signal, and then the OnDuration that the terminal device is performing on PCell and SCell will immediately transition to sleep status. When the next DRX cycle arrives, the DRX operation of the terminal device in PCell and SCell returns to normal.

By analyzing the normal processing method of the terminal device shown in FIG. 4 or FIG. 5, it may be considered that a certain amount of traffic may exist in a certain period of time. In this case, in fact, only PCell can meet the needs of service transmission for a period of time without using SCell. However, in the usual method, after the terminal device receives the GTS signal, only one OnDuration state on the PCell and the SCell changes, and when the next DRX cycle arrives, the SCell will also resume normal OnDuration. Therefore, the terminal equipment will generate unnecessary overhead and energy consumption on the SCell.

The normal processing method of terminal equipment has unnecessary overhead and energy consumption. The reason is that the PCell is only used for service transmission due to the small amount of traffic in a certain period of time. After receiving the GTS signal, the terminal equipment only There is an OnDuration state transition to a sleep state during a DRX cycle, and there is no subsequent operation on the SCell to reduce unnecessary PDCCH monitoring of the terminal device on the SCell.

Based on the above considerations, in the embodiment of the present application, in the case of a small amount of traffic, after the terminal device receives the GTS signal, further measures are taken on the SCell to reduce the PDCCH monitoring of the terminal device on the SCell to achieve further reduction of overhead and Purpose of energy consumption.

Considering that in the CA scenario, when the terminal device is configured with DRX, after the terminal device receives the GTS signal, this application further adds an operation for the SCell. There are two main methods: 1. After the terminal equipment receives the GTS signal, the secondary cell uses different DRX configuration parameters from the primary cell to shorten the OnDuration duration of the secondary cell, that is, shorten the duration of the secondary cell in the active or awake state; 2. After receiving the GTS signal, the terminal device deactivates the secondary cell or maintains the sleep state. These two methods can reduce the PDCCH monitoring of the terminal equipment on the secondary cell and reduce the power consumption of the terminal equipment.

The communication method provided in the embodiments of the present application is mainly applied to a CA scenario. For example, the CA scenario may be a CA scenario of a 5th-generation (5G) system, or a long-term evolution (LTE) ) CA scenario of the system.

FIG. 6 is a 5G system architecture diagram provided by an embodiment of the present application. The embodiments of the present application can be applied to a CA scenario of a 5G system, where a terminal device is connected to a PCell and several SCells, and these cells form a serving cell set of the terminal device. The base station gNB or ng-eNB of the PCell and SCell is responsible for providing the user equipment and control plane protocol functions of the 5G radio access network (new radio) to the terminal equipment.

FIG. 7 is an architecture diagram of an LTE system according to an embodiment of the present application. The embodiments of the present application can also be applied to the CA scenario of the LTE system. The base stations (evolved node B, eNB) of PCell and SCell provide the user equipment and control plane protocol functions of the LTE wireless access network (evolved terrestrial radio access, E-UTRA) for terminal equipment.

FIG. 8 is a schematic diagram of a CA scenario provided by an embodiment of the present application. A base station manages several cells, one of which serves as the PCell of the terminal device, and the remaining several can serve as the SCell of the terminal device.

The following briefly describes the network elements that may be involved in the embodiments of the present application. When the embodiment of this application is applied to a 5G system, it involves the gNB / ng-eNB sending an RRC message or MAC CE to the terminal device. The terminal device completes the corresponding operation according to the RRC message or the MAC CE instruction, and reports a confirmation message to the gNB / ng- eNB. The network elements involved are: gNB / ng-eNB and terminal equipment. When the embodiment of the present application is applied to an LTE system, the eNB sends an RRC message or a MAC CE to the terminal device. The terminal device completes the corresponding operation according to the RRC message or the MAC CE instruction, and reports a confirmation message to the eNB according to the situation. The network elements involved are: eNB and terminal equipment.

Based on the foregoing method 1. After the terminal device receives the GTS signal, the secondary cell adopts a DRX configuration different from that of the primary cell, and shortens the OnDuration duration of the secondary cell, that is, shortens the duration of the secondary cell in the active state or the awake state to reduce the terminal device. The PDCCH monitoring on the secondary cell reduces the power consumption of the terminal equipment.

FIG. 9 is a flowchart of a communication method according to an embodiment of the present application. The method may be based on a 5G system architecture or an LTE system architecture. The method is executed by a terminal device. The method mainly includes the following processing procedures.

Step 901: The terminal device receives a GTS signal within a first DRX cycle.

In one example, the terminal device receives a GTS signal from a network device (eg, a base station) during a first DRX cycle.

Step 902: In response to the GTS signal, the terminal device performs a DRX operation on the primary cell using the first configuration parameter set, and performs a DRX operation on the secondary cell using the second configuration parameter set. The DRX in the first DRX configuration parameter set continues. The length of the time timer is different from the length of the DRX duration timer in the second DRX configuration parameter set.

It can be understood that the above differences include two cases that are greater or less than one, that is, one case is that the length of the DRX duration timer in the first DRX configuration parameter set is greater than the DRX in the second DRX configuration parameter set The length of the duration timer; in another case, the length of the DRX duration timer in the first DRX configuration parameter set is smaller than the length of the DRX duration timer in the second DRX configuration parameter set.

In a possible implementation manner, during the Nth to N + Mth DRX cycles after the first DRX cycle, the secondary cell uses the second configuration parameter set for DRX operation, where N> = 1, M> = 0; or, within Tms, perform the DRX operation on the secondary cell by using the second configuration parameter set, where T> 0. According to this embodiment, a certain period of time is set for the secondary cell. After the terminal device receives the GTS signal, the secondary cell uses a DRX parameter configuration different from the primary cell within the period of time to shorten the “OnDuration” on the secondary cell "duration.

In a possible implementation manner, before the terminal device receives the GTS signal in the first DRX cycle, the terminal device is in an activated state or an awake state, wherein the terminal device monitors the PDCCH in the activated state or the awake state; After the terminal device receives the GTS signal in the first DRX cycle, the terminal device enters a sleep state for both the primary cell and the secondary cell during the first DRX cycle, wherein the terminal device does not monitor the PDCCH in the sleep state Or, the terminal device enters a sleep state for both the primary cell and the secondary cell in the first DRX cycle and K DRX cycles after the first DRX cycle, where K> = 1; or It is stated that the terminal device enters the sleep state for both the primary cell and the secondary cell within Xms, where X> 0. According to this embodiment, after receiving a GTS signal, a terminal device first enters a sleep state from an activated state or a wake-up state and maintains a certain period of time, thereby further saving power consumption of the terminal device.

In a possible implementation manner, the second DRX configuration parameter set further includes a length of the DRX inactivity timer, a length of the DRX uplink retransmission timer, a length of the DRX downlink retransmission timer, and a length of the DRX short cycle timer. One or more of the length and the length of the DRX long cycle timer. According to this embodiment, not only the length of the DRX duration timer different from that of the primary cell can be used for the secondary cell, but also the length of the DRX inactivity timer and the length of the DRX uplink retransmission timer that are different from the primary cell can be used for the secondary cell. One or more of the length of the DRX downlink retransmission timer, the length of the DRX short cycle timer, and the length of the DRX long cycle timer, thereby further saving power consumption of the terminal device.

It can be understood that the foregoing various possible implementation manners can be combined with each other to form multiple possible implementation manners, and these implementation manners are all within the scope disclosed in this specification.

In the embodiment of the present application, after the terminal device receives the GTS signal, the DRX parameter configuration on the secondary cell is different from that of the primary cell, and the length of the DRX duration timer on the secondary cell is shortened (that is, the “On Duration” duration). First, because the secondary cell uses a short "OnDuration" DRX configuration, this operation can reduce the PDCCH monitoring of the terminal device on the secondary cell and reduce the power consumption of the terminal device. In addition, the network device can flexibly control the number of serving cells that perform service transmission for the terminal device by adjusting the time for issuing the PDCCH scheduling information. For example, when only the primary cell can meet the service transmission requirements of the terminal device, the network device may choose to send the moment when the "OnDuration" on the secondary cell ends but the primary cell is still in the "OnDuration" state within a DRX cycle. PDCCH scheduling information, so that only the primary cell can be used for data transmission. Similarly, when the primary cell and one or some secondary cells are required to perform data transmission at the same time, the network device may choose to send the PDCCH scheduling information at a certain time when both the secondary cell and the primary cell are in the “OnDuration” state within a DRX cycle. . This operation can adjust the number of serving cells according to the amount of traffic, thereby avoiding unnecessary overhead.

FIG. 10 is a schematic diagram of a communication method according to an embodiment of the present application. This method is for scenario one: the GTS signal is sent before OnDuration. After the terminal device receives the GTS signal, the PCell and the next OnDuration on the SCell remain in a sleep state, and the terminal device no longer wakes up to monitor the PDCCH. When the next DRX cycle comes later, the normal DRX configuration is restored on the PCell, that is, an OnDuration starts normally on the PCell. The SCell will use different DRX configurations within a certain period of time according to the configuration, that is, a short OnDuration will be started on the SCell. At the same time, the BWP on the SCell is switched to Initial BWP (Initial BWP) or Default BWP (Default BWP). During the DRX configuration period using the short OnDuration on the SCell, if the terminal device receives the GTS signal again, the period duration of the DRX configuration using the short OnDuration on the SCell is updated. The SCell keeps the DRX configuration with a short OnDuration until the set cycle time is reached, and then restores the same ordinary DRX configuration as the PCell.

FIG. 11 is a schematic diagram of a communication method according to an embodiment of the present application. This method is for scenario two: the GTS signal is sent during the OnDuration. After the terminal device receives the GTS signal, the ongoing OnDuration on the PCell and SCell immediately transitions to the sleep state, and the terminal device no longer monitors the PDCCH. When the next DRX cycle comes later, the normal DRX configuration is restored on the PCell, that is, an OnDuration starts normally on the PCell. The SCell will use different DRX configurations within a certain period of time according to the configuration, that is, a short OnDuration will be started on the SCell. At the same time, the BWP on the SCell is switched to Initial BWP (Initial BWP) or Default BWP (Default BWP). During the DRX configuration period using the short OnDuration on the SCell, if the terminal device receives the GTS signal again, the period duration of the DRX configuration using the short OnDuration on the SCell is updated. The SCell keeps the DRX configuration with a short OnDuration until the set cycle time is reached, and then restores the same ordinary DRX configuration as the PCell.

FIG. 12 is a flowchart of another communication method according to an embodiment of the present application. This embodiment is applied to a 5G communication system as an example. The base station of the PCell and SCell connected by the UE is a 5G base station gNB, and may include the following operation flow.

Step 1201: The gNB sends an RRC reconfiguration message to the UE, where the RRC reconfiguration message carries DRX configuration information.

Among them, the gNB performs DRX configuration for the Scell on the UE through an RRC reconfiguration message. The content of the configuration may include, but is not limited to, specific DRX parameters for the SCell and involves the following timers: drx-onDurationTimer, drx-InactivityTimer, and drx-RetransmissionTimerDL and drx-RetransmissionTimerUL.

There are two ways to configure:

The first configuration method is to configure a DRX parameter set P_separate different from the ordinary DRX parameter set P_common. P_separate is a complete set of parameter configuration, which contains the specific parameter settings of the above related timers. According to specific requirements, the parameter set P_separate of different SCells can be different.

The second configuration method is to configure a scaling factor Δ _j . Assuming that the original DRX parameter is P _j , the specific DRX parameter used on the SCell is P _j * Δ _j . According to specific requirements, the scaling factors Δ _{j of} different parameters may be different; the parameters and scaling factors of different SCells may also be different;

In addition, the gNB performs DRX configuration for the Scell on the UE through an RRC reconfiguration message. The content of the configuration may further include: the application cycle duration of the specific DRX parameter for the SCell.

Step 1202: The UE sends an RRC reconfiguration completion message to the gNB.

It can be understood that after the UE completes the configuration, it sends an RRC reconfiguration completion message to the gNB, and the RRC reconfiguration completion message is an acknowledgement message.

In step 1203, the gNB sends a GTS signal to the UE.

In one example, after the PCell receives the GTS signal, the communication scheme in the embodiment of the present application is enabled.

In step 1204, the UE keeps the DRX parameter configuration of the PCell unchanged during the set DRX cycle duration, and applies the DRX parameter configuration of the specific SCell.

Step 1205: The UE switches the BWP on the SCell to an initial BWP or a default BWP.

It can be understood that step 1204 and step 1205 can be performed simultaneously, or step 1204 and step 1205 can be performed sequentially.

In step 1206, the gNB sends a GTS signal to the UE.

During the application of the SCell-specific DRX configuration, the Gell signal is received again on the PCell.

Step 1207: The UE updates the application cycle duration of the specific DRX parameter configuration on the SCell.

That is, if the GTS signal is received again on the PCell during the application of the specific DRX configuration of the SCell, the application cycle time of the specific DRX parameter configuration on the SCell is updated.

It can be understood that step 1206 and step 1207 are optional steps.

In step 1208, after the UE determines that the set application cycle duration of the SCell specific DRX parameter configuration is reached, the SCell resumes using the same common DRX parameter configuration as the PCell.

In the embodiment of the present application, the gNB provides the UE with specific DRX parameter configuration of the SCell, and notifies the UE to start using the specific DRX configuration on the SCell after the PCell receives the GTS signal, or notifies the UE to update the SCell application after the PCell receives the GTS signal again. Duration of a specific DRX configuration. After the PCell receives the GTS signal, a certain period of time is set for the SCell. Within this period of time, the SCell uses a DRX parameter configuration different from that of the PCell to shorten the OnDuration time on the SCell. Because the DCell configuration of the short OnDuration is used on the SCell, this operation can reduce the PDCCH monitoring of the UE on the SCell and reduce the UE power consumption.

Based on the foregoing method 2. After receiving the GTS signal, the terminal device deactivates or maintains the sleep state on the secondary cell to reduce the PDCCH monitoring of the terminal device on the secondary cell and reduce the power consumption of the terminal device.

FIG. 13 is a flowchart of another energy-saving processing method according to an embodiment of the present application. The method may be based on a 5G system architecture or an LTE system architecture. The execution body of the method is a terminal device. The method mainly includes the following processing procedures.

Step 1301: The terminal device receives a GTS signal within a first DRX cycle.

It can be understood that the terminal device can receive the GTS signal from the network device (for example, the base station) within the first DRX cycle.

Step 1302: In response to the GTS signal, the terminal device performs deactivation on the secondary cell to enter a deactivated state or enter a sleep state on the secondary cell; wherein the terminal device does not monitor the PDCCH in the deactivated state or the sleep state.

It can be understood that, in response to the GTS signal, the terminal device may further perform a DRX on the primary cell by using a first configuration parameter set, where the first configuration parameter set is a common configuration parameter set.

In a possible implementation manner, during the Nth to N + Mth DRX cycles after the first DRX cycle, the secondary cell is maintained in a deactivated state or a sleep state, where N> = 1, M > = 0; or, within Tms, maintain the deactivated state or sleep state for the secondary cell, where T> 0. According to this embodiment, after the terminal device receives the GTS signal, a certain period of time is set, and the secondary cell is deactivated to enter a deactivated state or enter a sleep state for the secondary cell within the period of time.

In a possible implementation manner, after the N + M DRX cycle, the terminal device uses the first DRX configuration parameter set for a primary cell to perform a DRX operation, and uses the first DRX for a secondary cell. The configuration parameter set performs DRX operations; or, after the Tms, the terminal device performs the DRX on the primary cell using the first DRX configuration parameter set, and performs the DRX on the secondary cell using the first DRX configuration parameter set. According to this embodiment, after the set cycle time is reached, the secondary cell is again subjected to DRX. This operation comprehensively considers the long-term situation of the network, and reactivating the secondary cell after a period of time can avoid affecting the service transmission of the terminal device in the case of subsequent increase in traffic.

FIG. 14 is a schematic diagram of another communication method according to an embodiment of the present application. This method is for scenario one: the GTS signal is sent before OnDuration. After receiving the GTS signal, the terminal device deactivates the SCell immediately and configures a period of time for maintaining the deactivated state. The next OnDuration on Pcell stays asleep, and the terminal device no longer wakes up to monitor the PDCCH. During the period when the SCell is in the deactivated state, if the terminal device receives the GTS signal again, the duration of the period in which the SCell remains in the deactivated state is updated. The SCell remains in a deactivated state until it reaches the set period duration, and is then reactivated.

FIG. 15 is a schematic diagram of another communication method according to an embodiment of the present application. This method is for scenario two: the GTS signal is sent during the OnDuration. After receiving the GTS signal, the terminal device immediately deactivates the SCell and configures a period of time to maintain the deactivated state. The ongoing OnDuration on the Pcell immediately transitions to the sleep state, and the terminal device no longer monitors the PDCCH. During the period when the SCell is in the deactivated state, if the terminal device receives the GTS signal again, the duration of the period in which the SCell remains in the deactivated state is updated. The SCell remains in a deactivated state until it reaches the set period duration, and is then reactivated.

In the embodiment of the present application, after the terminal device receives the GTS signal, subsequent operations on the SCell are added, that is, a certain period duration is set, and the SCell is deactivated within the period duration. The network device can directly deactivate the SCell for a period of time when the traffic is small according to the traffic of the terminal device. Therefore, this operation can reduce the PDCCH monitoring of the terminal device on the SCell and reduce the power consumption of the terminal device. At the same time, only the PCell is used to perform service transmission to the terminal equipment, thereby avoiding unnecessary overhead on the SCell.

The communication method provided by the embodiment of the present invention is described above, and the terminal device and the network device provided by the embodiment of the present invention will be described below.
