Description

Communication method and device

Technical Field

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

Background

In a wireless communication system, in order to save power consumption of a terminal device on the premise of ensuring effective transmission of data, a Discontinuous Reception (DRX) mechanism is introduced. Without the DRX mechanism, the terminal device may monitor a Physical Downlink Control Channel (PDCCH) subframe all the time, and check whether there is information from the serving cell. However, in practice, many times, the terminal device does not always perform effective information interaction with the network, and therefore, if the terminal device also continuously monitors the PDCCH, it is very power-consuming. Conversely, when DRX is configured, the terminal device may periodically enter a sleep mode at some time, and the terminal device does not need to continuously monitor the PDCCH, but wakes up from the sleep mode when monitoring is needed, so as to achieve the purpose of saving power for the terminal device. Although this has some effect on the delay of the data transmission, it makes sense to perform DRX in view of the power consumption of the terminal device if such delay does not affect the user experience. The DRX period configuration comprises two time periods, the time period marked by 'On Duration' is the time for the terminal equipment to monitor the PDCCH, and the terminal equipment is in an awakening state; the period of time identified as "Opportunity for DRX" is the DRX sleep time, i.e. the time the terminal device does not monitor the PDCCH for power saving, the terminal device is in a sleep state.

Carrier Aggregation (CA) is a technique for increasing transmission bandwidth to meet the requirement of peak rate per user and system capacity increase. The CA technology can aggregate 2 or more Component Carriers (CCs), thereby realizing a larger transmission bandwidth and effectively increasing the uplink and downlink transmission rate. The terminal equipment determines that at most several carriers can be simultaneously used for uplink and downlink transmission according to the capacity of the terminal equipment. A primary cell (primary cell, PCell) is a cell in which a terminal device performs initial connection establishment, or performs RRC connection reestablishment, or is a primary cell designated in a handover process. The PCell is responsible for Radio Resource Control (RRC) communication with the terminal device. A CC corresponding to the PCell is called a Primary Component Carrier (PCC); a secondary cell (SCell) is added after an initial security activation procedure through RRC connection reconfiguration for providing additional radio resources. The CC corresponding to the SCell is referred to as a Secondary Component Carrier (SCC).

In consideration of CA, when the terminal device configures DRX, if the terminal device does not have data to send or receive within a certain period of time, the base station may send a signal to enter a sleep state (GTS) to change a relevant Duration (On Duration) of the terminal device On the PCell and the SCell, thereby reducing PDCCH monitoring of the terminal device and achieving the purpose of saving energy. Scene one: GTS signals are transmitted before the "On Duration" period, and the terminal device will transition to sleep state for the upcoming "On Duration" period On the PCell and SCell without waking up the terminal device. And when the next DRX period comes later, the terminal equipment restores to normal DRX operation between the PCell and the SCell. Scene two: GTS signals are transmitted during the "On Duration" period, and the ongoing "On Duration" periods of the terminal device On the PCell and SCell will immediately transition to the sleep state. And when the next DRX period comes, the DRX operation of the terminal equipment between the PCell and the SCell is recovered to be normal.

As can be seen from the above, after the terminal device receives the GTS signal, only the state of one "On Duration" time period is changed On the PCell and the SCell, and when the next DRX cycle arrives, the state of the normal "On Duration" time period is recovered On the PCell and the SCell. Therefore, the power consumption of the terminal device is still large.

Disclosure of Invention

The embodiment of the application provides a communication method and equipment, and power consumption of terminal equipment is further saved on the premise of ensuring effective data transmission.

In a first aspect, a method of communication is provided. The terminal equipment receives a GTS signal in a first DRX period; the terminal equipment responds to the GTS signal, and performs DRX operation on the main cell by adopting a first configuration parameter set and performs DRX operation on the auxiliary cell by adopting a second configuration parameter set; wherein a length of a DRX duration timer in the first DRX configuration parameter set is different from a length of a 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, the terminal device uses the DRX parameter configuration different from that of the primary cell On the secondary cell, for example, shortens the length of the DRX Duration timer (i.e., "On Duration") On the secondary cell. Firstly, because the secondary cell adopts the short "On Duration" 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 for service transmission of the terminal device by adjusting the time for issuing the PDCCH scheduling information. For example, when only the primary cell can meet the traffic transmission requirement of the terminal device, the network device may select to send the PDCCH scheduling information at a time after the "On Duration" On the secondary cell ends but the "On Duration" On the primary cell is still in the state in one DRX cycle, so that data transmission using only the primary cell can be achieved. Similarly, when the primary cell and one or more secondary cells are required to perform data transmission simultaneously, the network device may select to transmit PDCCH scheduling information at a time in an "On Duration" state On both the secondary cell and the primary cell in one DRX cycle. This operation can adjust the number of serving cells according to the size of the traffic, thereby avoiding unnecessary overhead.

In one possible implementation, the second configuration parameter set is used for DRX operation of the secondary cell in the nth to N + M DRX cycles after the first DRX cycle, where N > -1 and M > -0; or within T ms, performing DRX operation on the secondary cell by adopting the second configuration parameter set, wherein T > 0. According to the embodiment, a certain period Duration is set for the secondary cell, and after the terminal equipment receives the GTS signal, the DRX parameter configuration different from that of the primary cell is used On the secondary cell within the period Duration, so as to shorten the "On Duration" Duration On the secondary cell.

In a possible implementation manner, before the terminal device receives a GTS signal in a first DRX cycle, the terminal device is in an active state or an awake state, wherein the terminal device monitors a PDCCH in the active state or the awake state; after the terminal equipment receives a GTS signal in a first DRX period, the terminal equipment enters a sleep state for both a main cell and an auxiliary cell in the first DRX period, wherein the terminal equipment does not monitor a PDCCH in the sleep state; or the terminal equipment enters a sleep state for both the main cell and the auxiliary cell in the first DRX period and K DRX periods after the first DRX period, wherein K > is 1; or the terminal equipment enters a sleep state for both the main cell and the auxiliary cell within Xms, wherein X > 0. According to the embodiment, after receiving the GTS signal, the terminal device first enters the sleep state from the active state or the awake state, and keeps for a certain period of time, thereby further saving the power consumption of the terminal device.

In one possible implementation, before the terminal device receives a GTS signal in a first DRX cycle, the terminal device is in a sleep state, wherein the terminal device does not monitor a PDCCH in the sleep state; after the terminal device receives a GTS signal in a first DRX period, the terminal device keeps a sleep state for a main cell and an auxiliary cell in the first DRX period and F DRX periods after the first DRX period, wherein F > is 1; alternatively, the terminal device maintains a sleep state for both the primary cell and the secondary cell at Yms, where Y > 0. According to the embodiment, after the terminal device receives the GTS signal, the current sleep state is kept for a certain period of time, so that the power consumption of the terminal device is further saved.

In one possible embodiment, after the terminal device receives a GTS signal in a first DRX cycle, the terminal device switches a first fractional Bandwidth (BWP) on the secondary cell to a second BWP in response to the GTS signal in the nth to N + M DRX cycles after the first DRX cycle; or, within Tms, switching the first BWP on the secondary cell to the second BWP; wherein a bandwidth width of the first BWP is greater than a bandwidth width of the second BWP. For example, the second BWP is an initial BWP or a default BWP. According to the embodiment, the bandwidth width of the secondary cell is adjusted, so that the power consumption of the terminal equipment is further saved.

In a possible implementation manner, before the terminal device receives a GTS signal in a first DRX cycle, the terminal device receives an RRC reconfiguration message, where the RRC reconfiguration message includes at least one of a value of N, a value of M, a value of T, a value of K, a value of X, a value of F, a value of Y, and the first DRX configuration parameter set and the second DRX configuration parameter set.

According to this embodiment, the same scaling factor may be set for different parameters, or different scaling factors may be set for different parameters.

In a possible embodiment, the second DRX configuration parameter set further comprises one or more of a length of a DRX inactivity timer, a length of a DRX uplink retransmission timer, a length of a DRX downlink retransmission timer, a length of a DRX short cycle timer, and a length of a DRX long cycle timer. According to the embodiment, not only the length of the DRX duration timer different from that of the main cell can be adopted for the auxiliary cell, but also one or more of the length of the DRX static timer, the length of the DRX uplink retransmission timer, 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 different from that of the main cell can be adopted for the auxiliary cell, so that the power consumption of the terminal equipment is further saved.

According to the embodiment, during the period that the secondary cell applies the specific DRX parameter configuration, if the terminal equipment receives the GTS signal again, the cycle duration of the secondary cell applying the specific DRX parameter configuration is updated. The operation can feed back the traffic situation in real time, and further reduce unnecessary power consumption and overhead of the terminal equipment on the secondary cell.

According to the embodiment, after the set cycle duration of the secondary cell applying the specific DRX configuration is reached, the normal DRX parameter configuration which is the same as that of the primary cell on the secondary cell is recovered. The operation comprehensively considers the long-term condition of the network, and the normal DRX parameter configuration of the auxiliary cell is recovered after a period of time, so that the influence on the service transmission of the terminal equipment under the condition of increased subsequent service volume can be avoided.

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., gbb, CU, DU) in a 5G system, such as a New Radio access Technology (NR).

To facilitate an understanding of the present application, several elements that will be introduced in the description of the present application are first introduced here:

and in an activated state or an awakened state, the terminal equipment monitors the PDCCH.

In 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 transmission and random access transmission in the serving cell, and does not perform downlink control monitoring (i.e., PDCCH monitoring) in the serving cell.

In a wireless communication system, a DRX mechanism is introduced to save power consumption of a terminal device while ensuring effective data transmission.

Fig. 1 is a schematic diagram of a DRX cycle configuration according to an embodiment of the present disclosure. The time period identifying "duration (OnDuration)" is the time that the terminal device monitors the PDCCH, the terminal device being in an awake state. The period of time identifying "DRX Opportunity (DRX)" is a DRX sleep time, i.e., a time when the terminal device does not monitor the PDCCH for power saving, and the terminal device is in a sleep state. The DRX mechanism has two cycle configurations of a long cycle and a short cycle, wherein the short cycle is optional parameter configuration. The terminal device may configure the DRX long cycle and the DRX short cycle at the same time, in which case the long cycle is typically configured to be an integer multiple of the short cycle.

Fig. 2 is a schematic diagram of a typical DRX operation mode according to an embodiment of the present disclosure. When configuring DRX, the terminal device first enters On Duration and starts a DRX Duration timer (DRX-On Duration timer) when each DRX cycle arrives. During the On Duration, the terminal device continuously monitors the PDCCH: if the scheduling information of the PDCCH is not received in the period of time, after the DRX duration timer is overtime, the terminal equipment enters a sleep state and stops monitoring the PDCCH; if the scheduling information of the PDCCH is received within this time, a DRX inactivity timer (DRX-inactivity timer) is immediately started or restarted, and the terminal device keeps monitoring the PDCCH while the DRX inactivity timer is running.

In addition, if there is uplink or downlink data that needs to be retransmitted, a DRX downlink retransmission timer (DRX-retransmission timer) and a DRX uplink retransmission timer (DRX-retransmission timer ul) are also started, and the two timers are configured for each hybrid automatic repeat request (HARQ) process and are the maximum duration for which the terminal device waits for a retransmission operation.

When the DRX inactivity timer is expired and the DRX downlink or uplink retransmission timer is not running, or when the terminal device receives a DRX command Medium Access Control (MAC) Control Element (CE), the terminal device enters a sleep mode. If the DRX short cycle is configured, using the DRX short cycle, and simultaneously starting or restarting a DRX short cycle timer (DRX-ShortCycleTimer); otherwise, DRX long cycle is used.

The terminal device uses the DRX long cycle when the DRX short cycle timer expires or when the long DRX command MAC CE is received.

Fig. 3 is a schematic diagram of a CA type according to an embodiment of the present application. CA types include three types: intra-band aggregation of contiguous CCs, intra-band aggregation of non-contiguous CCs, and inter-band aggregation.

The primary cell PCell is a cell in which the terminal device performs initial connection establishment, or performs RRC connection reestablishment, or is a designated primary cell in a handover process. The PCell is responsible for RRC communication with the terminal device. The CC corresponding to the PCell is called PCC; the secondary cell SCell is added through RRC connection reconfiguration after the initial security activation procedure for providing additional radio resources. The CC corresponding to the SCell is referred to as SCC.

Typically, a CA-configured terminal device may be connected to 1 PCell and up to 31 scells, which form a serving cell set for the terminal device, the serving cell set containing up to 32 serving cells. CA is a terminal device level property, and 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 an SCell for another terminal device.

In consideration of CA, when the terminal device configures DRX, if the terminal device does not have data to send or receive within a certain period of time, the base station may send a GTS signal to the PCell to change the related On durations of the terminal device On the PCell and SCell, reduce PDCCH monitoring of the terminal device, and achieve the purpose of saving energy. Generally, the terminal device receives the GTS signal, and the following processing method may be adopted.

Scene one: GTS signal sent before On Duration

Fig. 4 is a schematic diagram of a general processing method of the terminal device when the GTS signal is transmitted before the On Duration. As shown in fig. 4, when the terminal device does not need to perform information interaction with the network device for a period of time, the network device may send a GTS signal before a certain On Duration arrives, and then the terminal device will transition to a sleep state at the upcoming On durations On the PCell and SCell without waking up the terminal device. And when the next DRX period comes later, the terminal equipment restores to normal DRX operation between the PCell and the SCell.

Scene two: GTS signals are sent during the On Duration

Fig. 5 is a diagram illustrating a general processing method of the terminal device when the GTS signal is transmitted during the On Duration. As shown in fig. 5, when the terminal device has no data to transmit or receive during a certain On Duration, the network device may transmit a GTS signal, and then the On Duration that the terminal device is in progress On the PCell and SCell will immediately transition to the sleep state. And when the next DRX period comes, the DRX operation of the terminal equipment between the PCell and the SCell is recovered to be normal.

By analyzing the general processing method of the terminal device shown in fig. 4 or fig. 5, it is considered that there may be a case where the traffic volume is small in a certain period of time. In this case, only the PCell can actually meet the traffic transmission requirement for a period of time without using the SCell. However, in a general method, after the terminal device receives the GTS signal, only one On Duration state changes On the PCell and the SCell, respectively, and when the next DRX cycle arrives, the SCell may also recover to the normal On Duration. Therefore, the terminal device may generate unnecessary overhead and energy consumption on the SCell.

The reason why the normal processing method of the terminal device has unnecessary overhead and energy consumption is that the situation that only the PCell needs to be used for service transmission due to small traffic in a certain period of time is not considered, after the terminal device receives the GTS signal, only the On Duration state in one DRX cycle is converted into the sleep state On the SCell, and the SCell is not further operated subsequently to reduce unnecessary PDCCH monitoring of the terminal device On the SCell.

Based on the above consideration, in the embodiment of the present application, under the condition that the traffic volume is considered to be small, after the terminal device receives the GTS signal, further measures are taken for the SCell to reduce PDCCH monitoring of the terminal device on the SCell, so as to achieve the purpose of further reducing overhead and energy consumption.

Considering that in a CA scenario, after the terminal device receives a GTS signal when the terminal device configures DRX, the present application further increases the operation for the SCell. There are two main methods: 1. after the terminal equipment receives the GTS signal, the auxiliary cell adopts DRX configuration parameters different from those of the main cell to shorten the On Duration of the auxiliary cell, namely, the Duration of the auxiliary cell in an activated state or an awakening state is shortened; 2. and after receiving the GTS signal, the terminal equipment deactivates the auxiliary cell or keeps the sleep state. The two methods can reduce PDCCH monitoring of the terminal equipment on the secondary cell and reduce power consumption of the terminal equipment.

The communication method provided in the embodiment of the present application is mainly applied to a CA scenario, for example, the CA scenario may be a CA scenario of a fifth generation mobile communication technology (5th-generation, 5G) system, and may also be a CA scenario of a Long Term Evolution (LTE) system.

Fig. 6 is a diagram of a 5G system architecture according to an embodiment of the present application. The embodiment of the application can be applied to a CA scene of a 5G system, the terminal equipment is connected with 1 PCell and a plurality of SCells, and the cells form a service cell set of the terminal equipment. The base station of PCell and SCell, gNB or ng-eNB, is responsible for providing the terminal device with the user plane and control plane protocol functions of the 5G radio access Network (NR).

Fig. 7 is an LTE system architecture diagram according to an embodiment of the present application. The embodiment of the application can also be applied to the CA scene of the LTE system. An evolved node B (eNB) of the PCell and the SCell provides a user plane and control plane protocol function of an LTE radio access network (E-UTRA) for the terminal device.

Fig. 8 is a schematic diagram of a CA scenario provided in an embodiment of the present application. One base station manages a plurality of cells, one of which serves as a PCell of the terminal device, and the remaining plurality of scells which serve as the terminal device.

The following is a brief description of a network element to which embodiments of the present application may relate. When the embodiment of the application is applied to a 5G system, the gNB/ng-eNB sends RRC message or MAC CE to the terminal equipment, the terminal equipment completes corresponding operation according to the indication of the RRC message or the MAC CE, and reports confirmation message to the gNB/ng-eNB according to the condition. The involved network elements are: gNB/ng-eNB and terminal equipment. When the embodiment of the application is applied to an LTE system, the eNB sends RRC message or MAC CE to the terminal equipment, the terminal equipment completes corresponding operation according to the indication of the RRC message or the MAC CE, and reports confirmation message to the eNB according to the condition. The involved network elements are: eNB and terminal equipment.

Based On the method 1, after the terminal device receives the GTS signal, the secondary cell adopts the DRX configuration different from that of the primary cell, and shortens the On Duration of the secondary cell, that is, shortens the Duration of the secondary cell in the active state or the awake state, so as to reduce the PDCCH monitoring of the terminal device On the secondary cell and reduce the power consumption of the terminal device.

Fig. 9 is a flowchart of a communication method according to an embodiment of the present application, where the method may be based on a 5G system architecture or an LTE system architecture, an execution subject of the method is a terminal device, and the method mainly includes the following processing procedures.

In step 901, the terminal device receives a GTS signal in a first DRX cycle.

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

Step 902, the terminal device responds to the GTS signal, and performs DRX operation on the primary cell using the first configuration parameter set, and performs DRX operation on the secondary cell using the second configuration parameter set; wherein a length of a DRX duration timer in the first DRX configuration parameter set is different from a length of a DRX duration timer in the second DRX configuration parameter set.

It will be appreciated that the above differences include more or less than two cases, that is, one case where the length of the DRX duration timer in the first DRX configuration parameter set is greater than the length of the DRX duration timer in the second DRX configuration parameter set; another case is that 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.

It will be appreciated that the various possible embodiments described above may be combined with each other to form a variety of possible embodiments, all of which are within the scope of the present disclosure.

In the embodiment of the present application, after the terminal device receives the GTS signal, the DRX parameter configuration different from that of the primary cell is used On the secondary cell, and the length of the DRX Duration timer (i.e., "On Duration") On the secondary cell is shortened. Firstly, because the secondary cell adopts the short "On Duration" 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 for service transmission of the terminal device by adjusting the time for issuing the PDCCH scheduling information. For example, when only the primary cell can meet the traffic transmission requirement of the terminal device, the network device may select to send the PDCCH scheduling information at a time after the "On Duration" On the secondary cell ends but the "On Duration" On the primary cell is still in the "On Duration" state in one DRX cycle, so that data transmission using only the primary cell can be achieved. Similarly, when the primary cell and the certain secondary cell or the certain secondary cells are required to perform data transmission simultaneously, the network device may select to send the PDCCH scheduling information at a certain time in the "On Duration" state On both the secondary cell and the primary cell in one DRX cycle. This operation can adjust the number of serving cells according to the size of the traffic, thereby avoiding unnecessary overhead.

Fig. 10 is a schematic diagram of a communication method according to an embodiment of the present application. The method aims at a scene one: the GTS signal is transmitted before the On Duration. After the terminal device receives the GTS signal, the PCell and the next upcoming OnDuration on the SCell remain in the sleep state, and the terminal device no longer wakes up to monitor the PDCCH. When the next DRX period comes later, the normal DRX configuration is recovered On the PCell, namely one On Duration is started normally On the PCell. Different DRX configurations will be used On the SCell within a certain cycle Duration according to the configuration, i.e. a short On Duration is started On the SCell. Meanwhile, the BWP on the SCell is switched to initial BWP (initial BWP) or default BWP (default BWP). And in the DRX configuration period using the short OnDuration on the SCell, if the terminal equipment receives the GTS signal again, updating the cycle duration of the DRX configuration using the short OnDuration on the SCell. And the SCell keeps using the DRX configuration of the short On Duration until the set cycle Duration is reached, and then recovers the common DRX configuration which is the same as the PCell.

Fig. 11 is a schematic diagram of a communication method according to an embodiment of the present application. The method aims at a scene two: the GTS signal is transmitted during the On Duration. After the terminal equipment receives the GTS signal, the ongoing OnDuration on the PCell and the SCell is immediately converted into a sleep state, and the terminal equipment does not monitor the PDCCH any more. When the next DRX period comes later, the normal DRX configuration is recovered On the PCell, namely one On Duration is started normally On the PCell. Different DRX configurations will be used On the SCell within a certain cycle Duration according to the configuration, i.e. a short On Duration is started On the SCell. Meanwhile, the BWP on the SCell is switched to initial BWP (initial BWP) or default BWP (default BWP). And in the DRX configuration period using the short OnDuration on the SCell, if the terminal equipment receives the GTS signal again, updating the cycle duration of the DRX configuration using the short OnDuration on the SCell. And the SCell keeps using the DRX configuration of the short On Duration until the set cycle Duration is reached, and then recovers the common DRX configuration which is the same as the PCell.

Fig. 12 is a flowchart of another communication method according to an embodiment of the present application. In this embodiment, taking application to a 5G communication system as an example, a base station of a PCell and an SCell connected by a UE is a 5G base station gNB, and may include the following operation procedures.

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

And the gNB performs DRX configuration aiming at the Scell on the UE through the RRC reconfiguration message. The configured content may include, but is not limited to: specific DRX parameters for SCell, involve the following timers: drx-onDurationTimer, drx-InactivetyTimer, and drx-RecransmissionTimerDL and drx-RecransmissionTimerUL.

The configuration mode has two types:

in the first configuration, a DRX parameter set P _ prepare different from a normal DRX parameter set P _ common is configured. The P _ partition is a complete set of parameter configuration, which contains the specific parameter settings of the related timers. The parameter set P _ segment may be different for different scells according to specific requirements.

Second configuration, configuring the scaling factor Δ_j. Assume the original DRX parameter is P_jThe specific DRX parameter used on SCell is P_j*Δ_j. Scaling factors Δ of different parameters according to specific requirements_jMay be different; parameters and scaling of different SCellsThe zoom factor may also be different;

in addition, the gNB performs DRX configuration on the UE for the Scell through the RRC reconfiguration message. The configured content may further include: the application cycle duration of the specific DRX parameters for the SCell described above.

In step 1202, the UE sends an RRC reconfiguration complete message to the gNB.

It can be understood that after the UE completes the configuration, the UE sends an RRC reconfiguration complete message, i.e., an acknowledgement message, to the gNB.

Step 1203, the gNB sends a GTS signal to the UE.

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

In step 1204, the UE keeps the DRX parameter configuration of the PCell unchanged within 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 the initial BWP or the default BWP.

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

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

Wherein, the GTS signal is received again on the PCell during the application of the SCell-specific DRX configuration.

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

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

It is 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.

According to the embodiment of the application, the gNB provides the UE with the specific DRX parameter configuration of the SCell, and informs the UE to start adopting the specific DRX configuration on the SCell after the PCell receives the GTS signal, or informs the UE to update the cycle duration of the SCell applying the specific DRX configuration after the PCell receives the GTS signal again. After the PCell receives the GTS signal, a certain period duration is set for the SCell, a DRX parameter configuration different from the PCell is used on the SCell in the period duration, and the OnDuration duration on the SCell is shortened. Because the SCell adopts the DRX configuration of short On Duration, the operation can reduce the PDCCH monitoring of the UE On the SCell, and reduce the power consumption of the UE.

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

Fig. 13 is a flowchart of another energy saving processing method provided in this embodiment, where the method may be based on a 5G system architecture or an LTE system architecture, and an execution subject of the method is a terminal device, and the method mainly includes the following processing procedures.

Step 1301, the terminal device receives a GTS signal in the first DRX cycle.

It is to be appreciated that the terminal device can receive a GTS signal from a network device (e.g., a base station) during the first DRX cycle.

Step 1302, the terminal device deactivates the secondary cell to enter a deactivated state or enter a sleep state for the secondary cell in response to the GTS signal; and the terminal equipment does not monitor the PDCCH in the deactivation state or the sleep state.

It is understood that, in response to the GTS signal, the terminal device may further perform DRX with a first set of configuration parameters for the primary cell, where the first set of configuration parameters is a normal set of configuration parameters.

In a possible implementation manner, after the N + M DRX cycles, the terminal device performs DRX operation on the primary cell using the first DRX configuration parameter set, and performs DRX operation on the secondary cell using the first DRX configuration parameter set; or after the Tms, the terminal device performs DRX for the primary cell by using the first DRX configuration parameter set, and performs DRX for the secondary cell by using the first DRX configuration parameter set. According to the embodiment, after the set cycle duration is reached, the secondary cell is enabled to perform DRX again. The operation comprehensively considers the long-term condition of the network, and the secondary cell is reactivated after a period of time, so that the service transmission of the terminal equipment can be prevented from being influenced under the condition that the subsequent service volume is increased.

Fig. 14 is a schematic diagram of another communication method according to an embodiment of the present application. The method aims at a scene one: the GTS signal is transmitted before the On Duration. After receiving the GTS signal, the terminal device immediately deactivates the SCell (deactivation), and configures a period duration for maintaining a deactivated state (deactivated). The next upcoming On Duration On the Pcell remains in the sleep state and the terminal device no longer wakes up to monitor the PDCCH. And during the period that the SCell is in the deactivated state, if the terminal equipment receives the GTS signal again, updating the period duration of the SCell kept in the deactivated state. And the SCell keeps the deactivated state until the set period duration is reached, and is reactivated again.

Fig. 15 is a schematic diagram of another communication method according to an embodiment of the present application. The method aims at a scene two: the GTS signal is transmitted during the On Duration. After receiving the GTS signal, the terminal device immediately deactivates the SCell and configures a period duration for maintaining the deactivated state. The On Duration On the Pcell immediately transitions to the sleep state, and the terminal device no longer monitors the PDCCH. And during the period that the SCell is in the deactivated state, if the terminal equipment receives the GTS signal again, updating the period duration of the SCell kept in the deactivated state. And the SCell keeps the deactivated state until the set period duration is reached, and is reactivated again.

According to the embodiment of the application, after the terminal equipment receives the GTS signal, the subsequent operation aiming at the SCell is added, namely a certain period duration is set, and the SCell is deactivated within the period duration. The network device can directly deactivate the SCell within a period of time when the traffic is small according to the traffic of the terminal device, so that the operation can reduce PDCCH monitoring of the terminal device on the SCell and reduce the power consumption of the terminal device. Meanwhile, the terminal equipment is subjected to service transmission only through the PCell, so that unnecessary overhead on the SCell is avoided.

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 are described below.
