Description

Energy-saving signal transmission method and device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for transmitting an energy-saving signal.

Background

In the 5G NR system, in order to obtain downlink scheduling information, a terminal needs to monitor a Physical Downlink Control Channel (PDCCH) at each PDCCH monitoring opportunity (PDCCH monitoring occasion) to determine whether user scheduling information is transmitted. Wherein, one PDCCH monitoring opportunity corresponds to a time length, for example, the time length may be several symbols.

When the terminal configures Discontinuous Reception (DRX), the terminal will not continuously monitor the PDCCH. The terminal monitors the PDCCH only when a DRX activation period (on-duration) or an inactivity timer (inactivity timer) is not timed out, so as to reduce the power consumption of the terminal. Before the activation period of the DRX cycle, the base station may send a power-saving signal to the terminal for dynamically indicating whether the terminal performs PDCCH monitoring during the activation period of the next DRX cycle or cycles. The energy-saving signal is a physical layer signal of a PDCCH type, and the monitoring process of the energy-saving signal is consistent with the monitoring behavior of the PDCCH scheduled by a user.

The base station can configure a plurality of DRX groups for a service cell of the terminal, each DRX group has different activation duration, and under the condition that the terminal is configured with a plurality of DRX groups at the same time, how to determine the indicated DRX group through the energy-saving signal is the problem needing to be solved at present.

It is to be understood that the data so used are interchangeable under appropriate circumstances and can be implemented in sequences other than those illustrated or otherwise described herein with respect to the embodiments of the application, for example.

Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or device that comprises a list of elements is not necessarily limited to those elements explicitly listed, but may include other elements not expressly listed or inherent to such product or device.

The term module, as used herein, refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware or/and software code that is capable of performing the functionality associated with that element.

The embodiment of the application provides an energy-saving signal transmission method and device, which can be used for determining the DRX group indicated by an energy-saving signal aiming at the condition that at least two DRX groups are configured at the same time by a terminal.

The DRX mechanism is first briefly explained below.

Fig. 1 illustrates a DRX cycle. One DRX cycle includes a DRX active period (on-duration) and a DRX inactive period (DRX off, also called openness for DRX). During one DRX cycle, the terminal monitors the PDCCH only during a DRX active period (on-duration) period, and during a DRX inactive period (opportunity for DRX), the terminal enters a sleep mode in which the PDCCH is not received to reduce power consumption.

The DRX information (DRX-Info, i.e., DRX parameter) specifically includes the following items:

-DRX active period timer (DRX-onDurationTimer): the duration of continuously monitoring the PDCCH from the beginning of the DRX period;

-DRX slot offset (DRX-SlotOffset): a time delay from the beginning of the DRX activation timer (DRX-onDurationTimer);

DRX inactivity timer (DRX-inactivity timer): when the PDCCH indicates that new Uplink (UL) or Downlink (DL) data is transmitted, the PDCCH is started after receiving the data, and when the timer is overtime, the terminal enters an inactive state;

DRX downlink retransmission timer (DRX-retransmission timerdl): for each downlink Hybrid Automatic Repeat reQuest (HARQ) process, the maximum duration before the downlink retransmission data arrives;

DRX uplink retransmission timer (DRX-retransmission timer ul): for each uplink HARQ process, the maximum duration before the uplink retransmission data arrives;

DRX downlink HARQ RTT timer (DRX-HARQ-RTT-TimerDL): for each downlink HARQ process, a Media Access Control (MAC) entity needs to perform a minimum duration before performing downlink HARQ retransmission;

DRX uplink HARQ RTT timer (DRX-HARQ-RTT-timerll): for each uplink HARQ process, the MAC entity needs to perform the minimum duration before performing uplink HARQ retransmission.

The terminal is in an active state during any one of a DRX active timer (DRX-onDurationTimer), a DRX inactive timer (DRX-inactivity timer), a DRX downlink retransmission timer (DRX-retransmission timer dl), and a DRX uplink retransmission timer (DRX-retransmission timer ul) is in an active state.

When the terminal is configured with only one DRX group (i.e. only one set of DRX parameters), for one DRX cycle, the terminal performs discontinuous PDCCH monitoring on all serving cells only when a DRX active period (on-duration) or inactivity timer (DRX-inactivity timer) is not expired, and during the DRX inactive period (opportunity for DRX), the terminal enters a sleep mode in which the terminal does not receive other PDCCHs except for scheduling broadcast signaling to reduce power consumption.

The base station may configure multiple DRX groups for a serving cell of the terminal. The multiple DRX groups may have the same parameters except for different DRX active timer (DRX-on duration timer) and DRX inactive timer (DRX-inactive timer), for example, the following parameters may be the same: drx-SlotOffset, drx-retransmission timerl, drx-retransmission timerll, drx-HARQ-RTT-timerll. That is, the DRX cycles of different DRX groups are the same, but have different active durations.

The base station configures a DRX group for a main cell of the terminal, so that the main cell belongs to the DRX group. The base station may configure the same DRX group for different secondary cells of the terminal such that different secondary cells belong to the same DRX group. The base station may also configure different DRX groups for different secondary cells, such that different secondary cells belong to different DRX groups.

The secondary cells of the terminal may be divided into one or more secondary cell dormant groups, and one secondary cell dormant group may include one or more secondary cells. The base station can configure a DRX group for one secondary cell dormant group, so that the secondary cells in the secondary cell dormant group are all affiliated to the DRX group. The base station may also configure multiple DRX groups for one secondary cell dormant group, such as configuring a first DRX group and a second DRX group for one secondary cell dormant group, so that some secondary cells in the secondary cell dormant group are subordinate to the first DRX group and another part of secondary cells are subordinate to the second DRX group.

In Rel-16, the power saving signal configured in the primary cell during the inactive period of the DRX cycle has two functions: the first is Wake-up indication (Wake-up indication) for indicating whether a DRX active period timer of a next DRX cycle is turned on, i.e., whether a DRX-onDurationTimer is turned on; the second is a secondary cell (Scell) dormant indication, which is used to indicate a dormant behavior of a secondary cell dormant group configured by a higher layer signaling (for example, an RRC signaling, where an RRC is an abbreviation of Radio Resource Control and indicates Radio Resource Control), that is, to indicate whether to switch to a subset Bandwidth (BWP) without PDCCH configuration.

Fig. 2 illustrates a diagram of wake-up indication of a power saving signal in the case where a terminal configures one DXR group. As shown in fig. 2, the terminal receives a power saving signal (DCI with CRC coded by PS-RNTI, DCP for short, where DCI is an abbreviation of Downlink Control Information and represents Downlink Control Information, and CRC is an abbreviation of Cyclic Redundancy Check and represents Cyclic Redundancy Check) on the primary cell, and the first power saving signal 201 carries secondary cell sleep indication Information for indicating whether the primary cell and the secondary cell enter a sleep state during the activation period of the next DRX cycle; the second power saving signal 202 carries wake-up indication information for instructing the primary cell and the secondary cell to wake up during the next active period of the DRX cycle. And the terminal performs data transmission during the activation period of the DRX period of the main cell.

In the related art, when the terminal configures two DRX groups (a first DRX group and a second DRX group) at the same time, the terminal cannot determine which DRX group the power saving signal indicates. For example, if the terminal receives a MAC CE (i.e., DRX Command MAC CE, where CE is an acronym for control element and denotes a control unit) carrying a DRX Command or a MAC CE (Long DRX Command MAC) carrying a Long DRX Command, timers (including an active period timer and an inactive period timer) of each DRX group are stopped. The network device sends an energy saving signal carrying an awake instruction, but since the energy saving signal cannot explicitly instruct which DRX group activation period timer is started, the terminal cannot determine which DRX group DRX-onDurationTimer is started according to the awake instruction carried by the energy saving signal.

Further, in the prior art, when the primary cell and the secondary cell belong to different DRX groups, the active states of the primary cell and the secondary cell are inconsistent due to inconsistent parameter configurations of the two DRX groups, and monitoring of the energy saving signal based on the PDCCH is affected by a DRX cycle. As shown in fig. 3a, the primary cell belongs to the first DRX group, the secondary cell belongs to the second DRX group, data transmission is performed during the active period of the DRX cycle of the secondary cell in one DRX cycle after the first power saving signal 301, when the network device sends the second power saving signal 302, the secondary cell of the terminal is in the active period, and the primary cell is in the inactive period, according to the Rel-16 protocol, the power saving signal is monitored only outside the DRX inactive period, for the case shown in fig. 3a, the terminal does not receive the second power saving signal 302 because the secondary cell is in the active period, so that the power saving signal is disabled, and the power consumption of the terminal is increased.

Further, in the prior art, when a secondary cell in a secondary cell dormant group belongs to a different DRX group and the energy saving signal indicates that the secondary cell dormant group is dormant, all cells in the secondary cell dormant group are handed over to BWP without PDCCH configuration via BWP, which affects data transmission on the secondary cell. In one scenario as shown in fig. 3b, the secondary cell dormant group includes a first secondary cell and a second secondary cell, the first secondary cell belongs to a first DRX group and belongs to the same DRX group as the primary cell, the second secondary cell belongs to a second DRX group, and there is data transmission during the active period of the DRX cycle of the second DRX group, and the data transmission is not completed during the DRX cycle. The terminal receives a first energy saving signal 303 in the primary cell, where the first energy saving signal is used to instruct the secondary cell dormant group to adopt a dormant behavior in a next DRX cycle, so that data in a DRX active period of a second secondary cell cannot be transmitted.

In order to solve the above problem, embodiments of the present application provide a method and an apparatus for transmitting a power saving signal, which can explicitly indicate a DRX group through a power saving signal for a situation that a terminal configures at least two DRX groups at the same time.

Referring to fig. 4, a flowchart of an energy saving signal transmission method according to an embodiment of the present application is provided. As shown in fig. 4, the method mainly includes the following steps:

s401: the network device sends a power save signal.

Wherein the energy-saving signal carries at least one of wake-up indication information and secondary cell dormancy indication information. The secondary cell dormancy indication information is used for indicating dormancy behaviors of secondary cells belonging to at least one DRX group or a secondary cell dormancy group.

The dormant behavior of the secondary cell or the dormant group of secondary cells belonging to the at least one DRX group includes the secondary cell entering a dormant state or not entering a dormant state. Wherein, the one secondary cell entering the dormant state refers to switching the secondary cell to a bandwidth subset (BWP) without PDCCH configuration.

The wake-up indication information is used to indicate a sleep behavior of the at least one DRX group. In particular, the wake-up indication information may be used to indicate whether to turn on an activation timer of at least one DRX group, i.e. the wake-up behavior of cells belonging to the DRX group may be influenced by turning on or not turning on an active period timer of the DRX group. For a DRX group, the cells belonging to the DRX group may include one or various combinations of the following:

a primary cell;

one or more secondary cell dormant groups, wherein the secondary cells in the secondary cell dormant group all belong to the same DRX group;

and one or more secondary cells belonging to the DRX group are contained in the secondary cell dormant group, wherein part of the secondary cells in the secondary cell dormant group and the other part of the secondary cells are belonging to different DRX groups.

Since whether the DRX active period timer is running is one of the reasons for influencing whether the terminal is in an active state, the wake-up behavior of the terminal in the cell belonging to the DRX group can be influenced by turning on or not turning on the active period timer of the DRX group.

Optionally, the power saving signal may be carried on PDCCH.

S402: the terminal receives the power save signal.

Further, after receiving the energy saving signal, the terminal may specify the DRX group indicated by the energy saving signal according to at least one of wakeup indication information and auxiliary cell dormant indication information carried by the energy saving signal, and may further start or not start an active period timer for the corresponding DRX group according to the wakeup indication information, and determine a dormant behavior of an auxiliary cell or an auxiliary cell dormant group belonging to the corresponding DRX group according to the auxiliary cell dormant indication information. This process may be performed by processing module 502 in fig. 5.

In some embodiments of the present application, before step S401, the network device may further configure a listening position of the power saving signal for the terminal. Specifically, the network device may configure a monitoring position of the energy saving signal for the terminal through a search space set of a PDCCH configured by a high-level signaling, where the search space set includes the monitoring position of the energy saving signal; the network device may also configure the location of the set subframe as a monitoring location, for example, configure the set location related to the DRX cycle start location as the monitoring location; the network equipment can also configure the monitoring position of the energy-saving signal according to the monitoring range. The configuration of the listening position may be performed by processing module 602 in fig. 6.

The network equipment sends the energy-saving signal at the configured monitoring position, and the terminal receives the energy-saving signal at the configured monitoring position.

In some embodiments of the present application, for a network device, the network device sends an energy-saving signal in a primary cell. For a terminal, the terminal receives a power save signal in the primary cell. Alternatively, the network device may send the power saving signal in an inactive period of a DRX group to which the primary cell belongs, and the terminal may receive the power saving signal in an inactive period of the DRX group to which the primary cell belongs, or the network device may send the power saving signal in an intersection time of inactive periods of at least two DRX groups, and the terminal may receive the power saving signal in an intersection time of inactive periods of at least two DRX groups, or the network device may send the power saving signal in a union time of inactive periods of at least two DRX groups, and the terminal may receive the power saving signal in a union time of inactive periods of at least two DRX groups.

In other embodiments, the network device sends the energy-saving signal in the secondary cell, and the terminal receives the energy-saving signal in the secondary cell. Optionally, the network device sends an energy-saving signal in an inactive period of a DRX group to which the secondary cell belongs, and the terminal sends the energy-saving signal in an inactive period of the DRX group to which the secondary cell belongs, or the network device sends the energy-saving signal in an intersection time of inactive periods of at least two DRX groups, and the terminal receives the energy-saving signal in the intersection time of inactive periods of at least two DRX groups, or the network device sends the energy-saving signal in a union time of inactive periods of at least two DRX groups, and the terminal receives the energy-saving signal in a union time of inactive periods of at least two DRX groups.

In other embodiments, the network device sends the energy-saving signals in the primary cell and the secondary cell, and the terminal receives the energy-saving signals in the primary cell and the secondary cell.

It should be noted that the primary cell, the secondary cell, and the secondary cell dormant group in the embodiment of the present application are for a terminal, that is, for a terminal, there may be one primary cell and one or more secondary cells.

In some embodiments of the present application, the wake-up indication information carried in the energy-saving signal sent by the network device in the primary cell is used to indicate that at least two DRX groups start the active period timer, or is used to indicate that at least two DRX groups do not start the active period timer, and the terminal may determine to start the active period timers of the at least two DRX groups according to the wake-up indication information, or determine not to start the active period timers of the at least two DRX groups. For example, taking the configuration of two DRX groups (a first DRX group and a second DRX group) as an example, the wake-up indication information is 1 bit, a bit value of 0 indicates that the active period timers of the first DRX group and the second DRX group are not turned on, and a bit value of 1 indicates that the active period timers of the first DRX group and the second DRX group are turned on.

In some embodiments of the present application, the wake-up indication information carried in the energy-saving signal sent by the network device in the primary cell is used to indicate only one DRX group to start the active period timer, or is used to indicate only one DRX group not to start the active period timer, and the terminal may determine to start the active period timer of the DRX group according to the wake-up indication information, or determine not to start the active period timer of the DRX group. For example, taking configuration of two DRX groups (a first DRX group and a second DRX group) as an example, the wake-up indication information is 1 bit for indicating that the first DRX group turns on or does not turn on the activation timer, specifically, a bit value of 0 indicates that the activation timer of the first DRX group is not turned on, and a bit value of 1 indicates that the activation timer of the first DRX group is turned on.

In some embodiments of the present application, the network device sends, in the primary cell, wake-up indication information carried in a power-saving signal, to indicate whether each of the at least two DRX groups starts an active period timer. The wake-up indication information comprises at least two information fields, the at least two information fields correspond to at least two DRX groups one by one, each information field in the at least two information fields is used for indicating whether the corresponding DRX group starts an active period timer, and the terminal can determine to start the active period timer of each DRX group according to the wake-up indication information or determine not to start the active period timer of each DRX group. For example, taking configuring two DRX groups (a first DRX group and a second DRX group) as an example, the wake-up indication information includes a first information field and a second information field, the first information field corresponds to the first DRX group, the second information field corresponds to the second DRX group, the wake-up indication information has 2 bits, and the first information field and the second information field respectively occupy 1 bit. When the bit value of the first information domain is 1, indicating that the activation timer of the first DRX group is started, and when the bit value of the first information domain is 0, indicating that the activation timer of the first DRX group is not started; and when the bit value of the second information domain is 0, the activation timer of the second DRX group is not started, and when the bit value of the second information domain is 1, the activation timer of the second DRX group is started.

In some embodiments of the present application, in order to save signaling overhead, the wake-up indication information carried by the power saving signal sent by the network device in the primary cell may jointly indicate whether each of the at least two DRX groups starts the active period timer. Specifically, each value of the wake-up indication information is used in a combination form for indicating whether an active period timer of each DRX group of at least two DRX groups is started. For example, taking two DRX groups (a first DRX group and a second DRX group) as an example, the wake-up indication information is used to indicate whether the first DRX group and the second DRX group start the active period timer, the wake-up indication information has 2 bits and includes 4 values, which are "00", "01", "10", "11", "00" indicates the active period timer which does not start the first DRX group and the second DRX group, "01" indicates the active period timer which does not start the first DRX group and starts the second DRX group, "10" indicates the active period timer which starts the first DRX group and the active period timer which does not start the second DRX group, "11" indicates the active period timer which starts the first DRX group and the second DRX group.

In some embodiments of the present application, the network device sends an energy saving signal in the secondary cell, where the energy saving signal carries wake-up indication information for indicating whether to start an active period timer of at least one DRX group, where one DRX group of the at least one DRX group is a DRX group to which the secondary cell receiving the energy saving signal belongs. The terminal receives the energy-saving signal in the auxiliary cell and can determine whether to start the activation period timer of the corresponding DRX group according to the awakening indication information carried by the energy-saving signal. The above-described manner can be applied to a case where the primary cell and the secondary cell belong to different DRX groups.

For example, taking the configuration of two DRX groups (a first DRX group and a second DRX group) as an example, the wake-up indication information is 2 bits, the first bit is used to indicate whether to turn on the active timer of the first DRX group to which the secondary cell receiving the power saving signal belongs, and the second bit is used to indicate whether to turn on the active timer of the second DRX group. For example, the wake-up indication information is "10", which indicates that the active timer of the first DRX group to which the secondary cell receiving the power saving signal belongs is started, and the active timer of the second DRX group is not started.

In some embodiments of the present application, for a network device, secondary cell dormancy indication information carried in an energy saving signal sent by a first cell may be used to indicate a secondary cell dormancy group belonging to the same DRX group as the first cell or a dormancy behavior of a secondary cell. For the terminal, the secondary cell dormancy indication information carried in the energy-saving signal received in the first cell may be used to indicate a secondary cell dormant group belonging to the same DRX group as the first cell or a dormant behavior of the secondary cell. The first cell may be a primary cell or a secondary cell.

For example, the terminal configures a first DRX group and a second DRX group, and the secondary cells are divided into a first secondary cell dormant group and a second secondary cell dormant group, where the first secondary cell dormant group belongs to the first DRX group, that is, the secondary cells in the first secondary cell dormant group all belong to the first DRX group; and the second secondary cell dormant group belongs to the second DRX group, namely secondary cells in the second secondary cell dormant group all belong to the second DRX group. The primary cell belongs to a first DRX group.

If the terminal receives an energy-saving signal at a main cell belonging to the first DRX group, and the energy-saving signal carries auxiliary cell dormancy indication information, the terminal can determine the dormancy behavior of the first auxiliary cell dormancy group belonging to the first DRX group according to the auxiliary cell dormancy indication information.

If the terminal receives an energy-saving signal at a main cell belonging to the second DRX group, and the energy-saving signal carries auxiliary cell dormancy indication information, the terminal can determine the dormancy behavior of the second auxiliary cell dormancy group belonging to the second DRX group according to the auxiliary cell dormancy indication information.

If the terminal receives an energy-saving signal on one auxiliary cell in the first auxiliary cell dormant group belonging to the first DRX group, and the energy-saving signal carries auxiliary cell dormant indication information, the terminal can determine the dormant behaviors of all auxiliary cells in the first auxiliary cell dormant group belonging to the first DRX group according to the auxiliary cell dormant indication information.

If the terminal receives an energy-saving signal on one auxiliary cell in a second auxiliary cell dormant group belonging to the second DRX group, and the energy-saving signal carries auxiliary cell dormant indication information, the terminal can determine the dormant behaviors of all auxiliary cells in the second auxiliary cell dormant group belonging to the second DRX group according to the auxiliary cell dormant indication information.

In some embodiments of the present application, the secondary cell dormant indication information carried by the energy saving signal includes at least one information field, where the at least one information field corresponds to at least one secondary cell dormant group one to one, each information field includes at least one sub-information field, the at least one sub-information field corresponds to at least one DRX group one to one, and each information field is used to indicate a dormant behavior of a secondary cell dormant group belonging to a corresponding DRX group.

For example, taking the configuration of two secondary cell dormant groups (a first secondary cell dormant group and a second secondary cell dormant group) as an example, the secondary cell dormant indication information includes a first information field and a second information field, the first information field corresponds to the first secondary cell dormant group, the second information field corresponds to the second secondary cell dormant group, the secondary cell dormant indication information occupies 2 bits, the first information field includes a first sub-information field, the second information field includes a second sub-information field, the first sub-information field corresponds to the first DRX group, the second sub-information field corresponds to the second DRX group, and the first sub-information field and the second sub-information field each occupy 1 bit. The bit value of the first sub information domain is 1, which indicates that the first auxiliary cell sleeping group belonging to the first DRX group enters a sleeping state, and the bit value of the first sub information domain is 0, which indicates that the first auxiliary cell sleeping group belonging to the first DRX group does not enter the sleeping state; the bit value of the second sub information field is 1, which indicates that the second auxiliary cell sleeping group belonging to the second DRX group enters the sleeping state, and the bit value of the second sub information field is 0, which indicates that the second auxiliary cell sleeping group belonging to the second DRX group does not enter the sleeping state.

In some embodiments of the present application, the secondary cell dormancy indication information carried by the energy saving signal includes at least one information field, where the at least one information field corresponds to at least one DRX group one to one, each information field includes at least one sub-information field, the at least one sub-information field corresponds to the at least one secondary cell dormancy group one to one, and each sub-information field is used to indicate a dormancy behavior of a corresponding secondary cell dormancy group.

For example, taking the configuration of two DRX groups (a first DRX group and a second DRX group) as an example, the secondary cell dormant indication information includes a first information field and a second information field, the first information field corresponds to the first DRX group, the second information field corresponds to the second DRX group, the first to fourth secondary cell dormant groups are subordinate to the first DRX group, and the fifth secondary cell dormant group is subordinate to the second DRX group. The first information domain comprises a first sub information domain to a fourth sub information domain, the first sub information domain corresponds to a first auxiliary cell dormancy group, the second sub information domain corresponds to a second auxiliary cell dormancy group, the third sub information domain corresponds to a third auxiliary cell dormancy group, and the fourth sub information domain corresponds to a fourth auxiliary cell dormancy group; the second information field comprises a fifth sub information field, and the fifth sub information field corresponds to a fifth auxiliary cell dormant group. The first information domain and the second information domain respectively occupy N bits, the first bit of the N bits is used for indicating whether at least one auxiliary cell dormant group which belongs to the same DRX group exists in the at least one auxiliary cell dormant group which belongs to the same DRX group or not, N-1 bits are respectively used for indicating the dormant behavior of the at least one auxiliary cell dormant group which belongs to the same DRX group, and N is equal to the number of the auxiliary cell dormant groups which belong to the same DRX group plus 1. For example, the first information field is "10101", a first bit value 1 indicates that there is an auxiliary cell dormant group entering a dormant state from a first auxiliary cell dormant group to a fourth auxiliary cell dormant group belonging to the first DRX group, a second bit value 0 indicates that the first auxiliary cell dormant group does not enter the dormant state, a third bit value 1 indicates that the second auxiliary cell dormant group enters the dormant state, a fourth bit value 0 indicates that the third auxiliary cell dormant group does not enter the dormant state, and a fifth bit value 1 indicates that the fourth auxiliary cell dormant group enters the dormant state; the second information field is '00', the first bit value of 0 indicates that no secondary cell dormant group entering the dormant state exists in the secondary cell dormant group belonging to the second DRX group, and the second bit value of 0 indicates that the fifth secondary cell dormant group does not enter the dormant state.

In some embodiments of the present application, for a network device, secondary cell dormancy indication information carried in an energy saving signal sent on a first cell is used to indicate a dormancy behavior of a secondary cell belonging to the same DRX group as the first cell in a secondary cell dormancy group. For the terminal, the secondary cell dormancy indication information carried by the energy-saving signal received on the first cell is used to indicate the dormancy behavior of the secondary cell belonging to the same DRX group as the first cell in the secondary cell dormancy group. Wherein, at least one auxiliary cell and the main school cell in the auxiliary cell dormant group belong to the same DRX group, and at least two auxiliary cells belong to different DRX groups. The first cell may be a primary cell or a secondary cell.

For example, the terminal configures a first DRX group and a second DRX group, and the secondary cells are divided into a first secondary cell dormant group, where the first secondary cell dormant group is subordinate to the first DRX group and the second DRX group, that is, the first secondary cells in the first secondary cell dormant group are both subordinate to the first DRX group, and the second secondary cells in the secondary cell dormant group are subordinate to the second DRX group. The primary cell belongs to a first DRX group.

If the terminal receives an energy-saving signal at a main cell belonging to the first DRX group, and the energy-saving signal carries auxiliary cell dormancy indication information, the terminal can determine the dormancy behavior of a first auxiliary cell belonging to the first DRX group in the first auxiliary cell dormancy group according to the auxiliary cell dormancy indication information.

If the terminal receives an energy-saving signal at a first auxiliary cell belonging to the first DRX group, where the energy-saving signal carries auxiliary cell dormancy indication information, the terminal may determine, according to the auxiliary cell dormancy indication information, a dormancy behavior of the first auxiliary cell belonging to the first DRX group in the first auxiliary cell dormancy group.

If the terminal receives an energy-saving signal at a second auxiliary cell belonging to a second DRX group, and the energy-saving signal carries auxiliary cell dormancy indication information, the terminal can determine the dormancy behavior of the second auxiliary cell belonging to the second DRX group in the first auxiliary cell dormancy group according to the auxiliary cell dormancy indication information.

For another example, the terminal configures a first DRX group and a second DRX group, and the secondary cells are divided into a first secondary cell dormant group and a second secondary cell dormant group, where the first secondary cell dormant group is subordinate to the first DRX group and the second DRX group, that is, a first secondary cell in the first secondary cell dormant group is subordinate to the first DRX group, and a second secondary cell in the first secondary cell dormant group is subordinate to the second DRX group; the second secondary cell dormant group belongs to the first DRX group and the second DRX group, namely a third secondary cell in the second secondary cell dormant group belongs to the first DRX group, and a fourth secondary cell in the second secondary cell dormant group belongs to the second DRX group. The primary cell belongs to a first DRX group.

If the terminal receives an energy-saving signal at a main cell belonging to the first DRX group, where the energy-saving signal carries auxiliary cell dormancy indication information, the terminal may determine, according to the auxiliary cell dormancy indication information, a dormancy behavior of a first auxiliary cell belonging to the first DRX group in the first auxiliary cell dormancy group, and a dormancy behavior of a third auxiliary cell belonging to the first DRX group in the second auxiliary cell dormancy group.

If the terminal receives an energy-saving signal at an auxiliary cell belonging to the first DRX group, where the energy-saving signal carries auxiliary cell dormancy indication information, the terminal may determine, according to the auxiliary cell dormancy indication information, a dormancy behavior of a first auxiliary cell belonging to the first DRX group in the first auxiliary cell dormancy group, and a dormancy behavior of a third auxiliary cell belonging to the first DRX group in the second auxiliary cell dormancy group.

If the terminal receives an energy-saving signal at an auxiliary cell belonging to the second DRX group, where the energy-saving signal carries auxiliary cell dormancy indication information, the terminal may determine, according to the auxiliary cell dormancy indication information, a dormancy behavior of a second auxiliary cell belonging to the second DRX group in the first auxiliary cell dormancy group, and a dormancy behavior of a fourth auxiliary cell belonging to the second DRX group in the second auxiliary cell dormancy group.

In some embodiments of the present application, the secondary cell dormancy indication information carried by the energy saving signal includes at least one information field, where the at least one information field corresponds to at least one secondary cell dormancy group in a one-to-one manner, each information field includes at least one sub-information field, the at least one sub-information field corresponds to at least one DRX group in a one-to-one manner, and each sub-information field is used to indicate a dormancy behavior of a secondary cell belonging to a corresponding DRX group in the corresponding secondary cell dormancy group. Wherein at least two secondary cells in the at least one secondary cell dormant group belong to different DRX groups. The sub information fields corresponding to the DRX groups one to one may be a display indication, an implicit indication, or configured through a high-level signaling.

For example, taking the configuration of two secondary cell dormant groups (a first secondary cell dormant group and a second secondary cell dormant group) as an example, the secondary cell dormant indication information includes a first information field and a second information field, the first information field corresponds to the first secondary cell dormant group, the first secondary cell dormant group includes a first secondary cell and a second secondary cell, the first secondary cell is subordinate to a first DRX group, and the second secondary cell is subordinate to a second DRX group, that is, the first secondary cell and the second secondary cell in the first secondary cell dormant group are subordinate to different DRX groups; the second information domain corresponds to a second auxiliary cell dormant group, the second auxiliary cell dormant group comprises a third auxiliary cell, a fourth auxiliary cell and a fifth auxiliary cell, the third auxiliary cell belongs to a second DRX group, and the fourth auxiliary cell and the fifth auxiliary cell belong to the first DRX group, namely the third auxiliary cell to the fifth auxiliary cell in the second auxiliary cell dormant group belong to different DRX groups. The first information domain comprises a first sub information domain and a second sub information domain, the first sub information domain is used for indicating the dormancy behavior of the auxiliary cells belonging to the first DRX group in the first auxiliary cell dormancy group, and the second sub information domain is used for indicating the dormancy behavior of the auxiliary cells belonging to the second DRX group in the first auxiliary cell dormancy group; the second information domain comprises a third sub information domain and a fourth sub information domain, the third sub information domain is used for indicating the dormancy behavior of the auxiliary cells belonging to the first DRX group in the second auxiliary cell dormancy group, and the fourth sub information domain is used for indicating the dormancy behavior of the auxiliary cells belonging to the second DRX group in the second auxiliary cell dormancy group. For example, the first sub information field is "10", which indicates that a first secondary cell belonging to the first DRX group in the first secondary cell dormant group enters the dormant state, and a second secondary cell belonging to the second DRZ group in the first secondary cell dormant group does not enter the dormant state; the second sub information field is "11", which indicates that a third secondary cell belonging to the first DRX group in the second secondary cell dormant group enters the dormant state, and a fourth secondary cell and a fifth secondary cell belonging to the second DRZ group in the second secondary cell dormant group enter the dormant state.

For another example, taking configuring two secondary cell dormant groups (a first secondary cell dormant group and a second secondary cell dormant group) as an example, the secondary cell dormant indication information includes a first information field and a second information field, the first information field corresponds to the first secondary cell dormant group, the first secondary cell dormant group includes first to fourth secondary cells, the first and second secondary cells belong to a first DRX group, and the third and fourth secondary cells belong to a second DRX group, that is, the first to fourth secondary cells in the first secondary cell dormant group belong to different DRX groups; the second information domain corresponds to a second auxiliary cell dormant group, the second auxiliary cell dormant group comprises a fifth auxiliary cell, and the fifth auxiliary cell belongs to the first DRX group. The first information domain comprises a first sub information domain, the second information domain comprises a second sub information domain, and the first sub information domain is used for indicating the dormancy behaviors of a first auxiliary cell and a second auxiliary cell belonging to a first DRX group in a first auxiliary cell dormancy group; the second sub information field is used for indicating the dormancy behavior of a fifth secondary cell belonging to the first DRX group in the second secondary cell dormancy group. For example, the first sub information field is "1", which indicates that the first secondary cell and the second secondary cell belonging to the first DRX group in the first secondary cell dormant group enter the dormant state; the second sub information field is "0" and indicates that a fifth secondary cell belonging to the first DRX group in the second secondary cell dormant group does not enter the dormant state.

In some embodiments of the present application, in order to save resource overhead, the information domain may be used to jointly indicate the sleep behavior of secondary cells belonging to different DRX groups. Optionally, the secondary cell dormancy indication information includes at least one information field, where the at least one information field corresponds to at least one secondary cell dormancy group one to one, and each information field is used to indicate a combination form of dormancy behaviors of secondary cells belonging to different DRX groups in the corresponding secondary cell dormancy group.

For example, taking the configuration of two secondary cell dormant groups (a first secondary cell dormant group and a second secondary cell dormant group) as an example, the secondary cell dormant indication information includes a first information field and a second information field, the first information field corresponds to the first secondary cell dormant group, the first secondary cell dormant group includes a first secondary cell and a second secondary cell, the first secondary cell is subordinate to a first DRX group, and the second secondary cell is subordinate to a second DRX group, that is, the first secondary cell and the second secondary cell in the first secondary cell dormant group are subordinate to different DRX groups; the second information domain corresponds to a second auxiliary cell dormant group, the second auxiliary cell dormant group comprises a third auxiliary cell, a fourth auxiliary cell and a fifth auxiliary cell, the third auxiliary cell belongs to a second DRX group, and the fourth auxiliary cell and the fifth auxiliary cell belong to the first DRX group, namely the third auxiliary cell to the fifth auxiliary cell in the second auxiliary cell dormant group belong to different DRX groups. The first information field is used for indicating the dormancy behaviors of the secondary cells belonging to the first DRX group and the second DRX group in the first secondary cell dormancy group; the second information field is used for indicating the dormancy behaviors of the secondary cells belonging to the first DRX group and the second DRX group in the second secondary cell dormancy group. For example, the first information field is "10", which indicates that a first secondary cell belonging to the first DRX group in the first secondary cell dormant group enters the dormant state, and a second secondary cell belonging to the second DRZ group in the first secondary cell dormant group does not enter the dormant state; the second information field is "11", which indicates that a third secondary cell belonging to the first DRX group in the second secondary cell dormant group enters the dormant state, and a fourth secondary cell and a fifth secondary cell belonging to the second DRZ group in the second secondary cell dormant group enter the dormant state.

Of course, the meaning of the secondary cell dormancy indication information carried by the energy saving signal received on the primary cell may also include a combination of the above-listed meanings. For example, the secondary cell dormancy indication information may indicate the dormancy behavior of the secondary cell dormancy group belonging to the same DRX group, and the dormancy behavior of some secondary cells in one secondary cell dormancy group.

For example, the terminal configures a first DRX group and a second DRX group, and the secondary cells are divided into a first secondary cell dormant group and a second secondary cell dormant group, where the first secondary cell dormant group belongs to the first DRX group, that is, all the secondary cells in the first secondary cell dormant group belong to the first DRX group; the second secondary cell dormant group belongs to the first DRX group and the second DRX group, namely, the first secondary cells in the second secondary cell dormant group are all belonged to the first DRX group, and the second secondary cells in the second secondary cell dormant group are belonged to the second DRX group. The primary cell belongs to a first DRX group.

If the terminal receives an energy-saving signal at a main cell belonging to the first DRX, and the energy-saving signal carries auxiliary cell dormancy indication information, the terminal can determine all auxiliary cells in a first auxiliary cell dormancy group belonging to the first DRX group and the dormancy behavior of first auxiliary cells in a second auxiliary cell dormancy group belonging to the first DRX group according to the auxiliary cell dormancy indication information.

In some embodiments of the present application, for the network device, the secondary cell dormancy indication information used for indicating the dormancy behavior of the secondary cell dormancy group or the secondary cell belonging to the same DRX group as the secondary cell sending the energy-saving signal has, for different DRX groups, corresponding secondary cell dormancy indication fields, where each secondary cell dormancy indication field is only used for indicating the dormancy behavior of the corresponding secondary cell dormancy group or the secondary cell.

When an auxiliary cell in an auxiliary cell dormant group belongs to different DRX groups, in order to avoid that forced binding of an active period caused by inconsistency of an active period timer influences data reception or terminal power saving, the auxiliary cell dormant indication information carried by the energy-saving signal can not carry out dormant indication on the auxiliary cell dormant group; or the auxiliary cell in the auxiliary cell dormant group does not enter the dormant state according to the auxiliary cell dormant indication information; and then, the secondary cell dormancy indication information indicates the dormancy behavior of the secondary cells in the secondary cell dormancy group according to the set criteria, for example, indicates the dormancy behavior of the secondary cells in the secondary cell dormancy group according to the feedback information sent by the terminal, or performs the corresponding dormancy behavior according to the secondary cell dormancy indication in the corresponding DRX group.
