Description

Signal transmission method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a signal transmission method and apparatus.

Background

Currently, discontinuous reception (discontinuous reception, DRX) mechanisms are introduced in communication systems. Under the DRX mechanism, the terminal equipment in a radio resource control (radio resource control, RRC) connection state can enter an active time period and an inactive time period, when the terminal equipment enters the active time period, the terminal equipment detects a downlink control channel (physical downlink control channel, PDCCH), and when the terminal equipment enters the inactive time period, the terminal equipment does not detect the PDCCH, so that the purpose of reducing the power consumption of the terminal is achieved.

However, in the current DRX mechanism, even if the terminal device is in the deactivation period, the terminal device may still need to receive or transmit other signals, for example, these other signals include a synchronization signal block (synchronization signal block, SSB) signal, a physical random access channel (physical random access channel, PRACH) signal, etc., so that the base station cannot turn off transmission of the other signals, resulting in greater power consumption of the base station.

Currently, for the communication system shown in fig. 1, in order to save power consumption of the terminal device 102, a discontinuous reception (discontinuous reception, DRX) mechanism and a secondary cell (Scell) sleep mechanism are introduced.

The following describes the content of the DRX mechanism:

1. DRX mechanism

The mechanism of DRX is to configure a DRX cycle for a terminal device in a radio resource control (radio resource control, RRC) connected state. The DRX cycle consists of "Duration" (on Duration) and "opportunity for DRX" (Opportunity for DRX): during the "duration" period, the terminal device detects and receives a physical downlink control channel (physical downlink control channel, PDCCH); and in the period of the opportunity of DRX, the terminal equipment does not detect the PDCCH so as to save power consumption.

Herein, the "duration" period is also referred to as an active period, and the "opportunity of DRX" period is also referred to as a deactivated period. Fig. 2 is a schematic diagram of an exemplary DRX basic model provided in the present application. As shown in fig. 2, the terminal device in the RRC connected state periodically enters an activation period and a deactivation period, and when the terminal device enters the activation period, the terminal device detects the PDCCH, and when the terminal device enters the deactivation period, the terminal device does not detect the PDCCH any more, that is, the terminal device is not required to be in a state of detecting the PDCCH all the time, thereby achieving the purpose of reducing power consumption of the terminal.

Currently, the base station transmits DRX configuration information to the terminal device, so that the terminal device enters an active mode in a specified period of time based on the DRX configuration information, and enters a deactivated mode in the rest of time, so as to realize dormancy under the DRX mechanism. Specifically, the following parameters are mainly included in the DRX configuration:

activation time timer (on Duration Timer): it is understood that a continuous number of downlink subframes indicates the time that the terminal device can sustain after waking up. Within the continuous downlink subframe number, the terminal device needs to monitor the physical downlink control channel.

DRX Inactivity Timer (DRX-Inactivity Timer): also understood as a continuous number of downlink subframes. The DRX inactivity timer is started when the terminal device successfully demodulates the first symbol after receiving the PDCCH which belongs to scheduling a new transmission (uplink or downlink) of the terminal device, and indicates a duration of the corresponding MAC to monitor the PDCCH after receiving a PDCCH indicating the new transmission. That is, it is also necessary to continue listening to the physical downlink control channel during the timing period of the DRX inactivity timer.

A downlink hybrid automatic repeat request (hybrid automatic repeat request, HARQ) Round Trip Time (RTT) Timer (Timer) and a downlink DRX retransmission Timer (DRX-Retransmission Timer): when the terminal device receives 1 downlink control information (downlink control information, DCI) indicating that a physical downlink shared control channel (physical downlink shared channel, PDSCH) transmission or a downlink semi-persistent scheduling (semi-persistent scheduling, SPS) PDSCH transmission is received (without distinguishing whether PDSCH is a new transmission or a retransmission), the terminal device starts downlink HARQ-RTT-Timer and stops downlink DRX retransmission Timer at the first symbol start time after the end symbol of the physical uplink control channel (physical uplink control channel, PUCCH) carrying feedback information "ACK/NACK" of the PDSCH transmission; when the downlink HARQ-RTT-Timer ends and the terminal device does not successfully receive the PDSCH transmission, a downlink DRX retransmission Timer is started, and if the terminal device successfully receives the PDSCH transmission, downlink Retransmission Timer is not started.

Uplink hybrid automatic repeat request (hybrid automatic repeat request, HARQ) Round Trip Time (RTT) Timer (Timer) and uplink DRX retransmission Timer (DRX-Retransmission Timer): when the terminal device receives 1 DCI indicating that a physical uplink shared control channel (physical uplink shared channel, PUSCH) transmission or a PUSCH transmission of an uplink grant (CG) type is activated, the terminal device starts an uplink HARQ-RTT-Timer and stops an uplink DRX retransmission Timer at a first symbol start time after an end symbol of a first repetition of the PUSCH transmission; and starting the uplink Retransmission Timer when the uplink HARQ-RTT-Timer is ended.

In summary, the terminal device is considered to be in the active period of time in any of the following cases, and otherwise, in the inactive period of time: an active time timer, a DRX inactive timer, a downlink DRX retransmission timer, and an uplink DRX retransmission timer.

In addition, under the DRX mechanism, when the terminal device sends a scheduling request and the scheduling request is in a suspension "pending" state, and when the terminal device receives the PDCCH after the end of the non-contention based random access procedure, the terminal device indicates that a new transmission of a cell radio network temporary identity scrambling has not been successfully received, the terminal device is also considered to be in an active period.

That is, with the DRX mechanism, during the operation of the active time timer, the DRX inactivity timer, the downlink DRX retransmission timer, the uplink DRX retransmission timer, and when the terminal device transmits a scheduling request and the scheduling request is in a suspended "pending" state and the terminal device receives a PDCCH indicating that a new transmission of one cell radio network temporary identity scrambling has not been successfully received, the terminal device is in a period in which detection of the PDCCH is performed, and in the remaining periods, the terminal device is in a deactivated period in which no PDCCH detection is performed, so as to reduce power consumption of the terminal device.

The deactivation period may also be referred to herein as a sleep period under the DRX mechanism.

The following describes the content of the Scell dormancy mechanism:

scell dormancy mechanisms refer to: when there is no data transmission on the SCell, the terminal device enters a dormant state on the SCell (in this application, the SCell that needs to be dormant is also referred to as dormant SCell). When the terminal device enters a dormant state on the dormant Scell, the terminal device does not perform reception of a downlink signal or transmission of an uplink signal except for performing channel state information (channel state information, CSI) measurement. It can be seen that in this state the terminal device power consumption is relatively low.

Correspondingly, for the non-dormant Scell, the terminal device still detects the PDCCH more frequently, for example, every downlink timeslot detects the PDCCH, and can perform CSI measurement and reporting. It can be seen that in this state, the terminal device consumes relatively large power.

Currently, the base station achieves dormancy of the terminal device on the Scell by sending a DCI indication to the terminal device.

Specifically, when the terminal device has a data transmission requirement on the Scell, the base station may send a DCI indication to the terminal device on the Pcell of the terminal device to instruct the terminal device to sleep on the Scell, and accordingly, the terminal device enters a sleep state on the Scell according to the DCI indication received on the Pcell; and when the terminal equipment does not have a transmission requirement on the Scell, the base station can instruct the terminal equipment to rapidly switch to a non-dormant state on the Scell through the corresponding DCI again so as to detect the scheduling information and transmit the data.

That is, in the Scell dormant mechanism, the terminal device may indicate to enter Scell dormant through DCI received by the base station on the Pcell, so that the terminal device enters a period of time (which may also be referred to as a dormant period in the Scell dormant mechanism in this application) in which no downlink signal reception or uplink signal transmission is performed except for CSI measurement on the dormant Scell, thereby reducing power consumption of the terminal device.

However, the DRX mechanism and the rescell sleep mechanism still have the following problems:

when the power consumption of the terminal device is reduced based on the DRX mechanism, the terminal device may still perform reception or transmission of some signals during a sleep period under the DRX mechanism, where some signals include, for example: a synchronization signal block (synchronization signal block, SSB), a physical random access channel (physical random access channel, PRACH); 2) System information (system information, SI)/Random Access (RA)/Temporary Cell (TC)/Paging/Power Save (PS) radio network Temporary identity (radio network Temporary identifier, RNTI) scrambled PDCCH; 3) SPS PDSCH; 4) CG PUSCH; 5) HARQ-ACK for SPS PDSCH; 6) SR/BFR. Thus, for the DRX mechanism, the terminal device is not truly dormant when the terminal device is in the dormant period under the DRX mechanism. Accordingly, the base station cannot turn off the transmission of the signals to sleep, otherwise, the receiving and transmitting of the terminal device are affected. In addition, the DRX configuration is configured through RRC signaling, and the duration between two RRC reconfiguration is long, resulting in poor flexibility of the DRX configuration.

For the Scell dormant mechanism, after the base station instructs the terminal device to enter the dormant state on the Scell, the terminal device may still transmit some signals during the dormant period of the Scell, for example, the base station may still transmit SSB on the Scell, and accordingly, the terminal device continues to detect SSB on the dormant Scell even if it is instructed to dormant on the Scell. Thus, the terminal device is not truly dormant when it is in the sleep period under the Scell sleep mechanism. The base station cannot turn off the transmission of the SSB signal, so that deep dormancy of the terminal device and the base station cannot be achieved.

That is, no matter the DRX sleep mechanism or the Scell sleep mechanism, when the terminal device is in the sleep period, the terminal device does not actually sleep, and accordingly, the base station cannot actually sleep, so that the power consumption of the terminal device or the power consumption of the base station cannot be further reduced.

In view of this, embodiments of the present application provide a signal transmission method and apparatus.

Fig. 3 is a schematic flow chart of a signal transmission method according to an embodiment of the present application. As shown in fig. 3, the signal transmission method includes: s301 and S302.

S301, the access network equipment sends first information to the terminal equipment, and correspondingly, the terminal equipment receives the first information; wherein the first information indicates a first mode, the first mode indicates a transmitting and receiving state of the first signal, and the transmitting and receiving state includes any one of the following transmitting and receiving states: transmitting, receiving, not transmitting, not receiving.

S302, determining the receiving and transmitting state of the first signal according to the first mode.

In this embodiment, the access network device may send the first information bearer to the terminal device in the MAC-CE or in the DCI. And for the terminal device, the first information may be received on the Pcell, the first information may be received on the Scell, or may be received on both the Pcell and the Scell, which does not form a limitation of the present application.

In particular, the first signals described herein may include at least one of a first set of signals, a second set of signals, a third set of signals, and a fourth set of signals:

wherein the first set of signals includes any one or more of the following signals: a cell radio network temporary identity (cell radio network temporary identifier, C-RNTI) scrambled PDCCH, a configuration scheduling radio network temporary identity (configured scheduling radio network temporary identifier, CS-RNTI) scrambled PDCCH, a slot format configuration (slot format indicators, SFI) -RNTI scrambled PDCCH, an INI-RNTI scrambled PDCCH, a cancel indication (Cancellation indication, CI) -RNTI scrambled PDCCH, physical uplink control channel uplink power control information (also referred to as TPC-PUCCH) -RNTI scrambled PDCCH, physical uplink shared channel uplink power control information (also referred to as TPC-PUSCH-RNTI) -RNTI scrambled PDCCH, dynamically scheduled physical downlink shared channel, channel sounding reference signal uplink power control information (also referred to as TPC-SRS) -RNTI scrambled PDCCH, availability indication (Availability indication, AI) -RNTI scrambled PDCCH.

The second group of signals includes any one or more of the following: hybrid automatic repeat request acknowledgement (HARQ-ACK) of dynamically scheduled physical downlink shared channel (pdcch), aperiodic sounding reference signal (a-SRS), periodic sounding reference signal (P-SRS), semi-static sounding reference signal (SP-SRS), aperiodic channel state information (a-SRS), periodic channel state information (P-SRS), semi-static channel state information (SP-SRS), dynamic Grant (DG) PUSCH.

The third set of signals includes any one or more of the following: SSB, BFR, semi-persistent scheduling physical downlink data channel (SPS PDSCH), system information (system information, SI)/Random Access (RA)/Temporary Cell (TC)/Paging/Power Save (PS) -RNTI scrambled PDCCH.

The fourth set of signals includes any one or more of the following: grant physical uplink shared channel (CG PUSCH), hybrid automatic repeat request acknowledgement (HARQ-ACK for SPS PDSCH), scheduling Request (SR), physical Random Access Channel (PRACH) for semi-persistent scheduled physical downlink shared channel.

It can be seen that, among the four sets of signals, the first set of signals and the third set of signals are downlink signals, the second set of signals and the fourth set of signals are uplink signals, and the first set of signals and the second set of signals are affected by the DRX configuration. Therefore, in this application, to facilitate signal discrimination, a first set of signals is also referred to as a first type of downlink signals, a second set of signals is also referred to as a first type of uplink signals, a third set of signals is also referred to as a second type of downlink signals, and a fourth set of signals is also referred to as a second type of uplink signals. Wherein, the first type of signal (including the first type of downlink signal and the first type of uplink signal) is affected by the DRX configuration, which may also be considered that the access network device side and the terminal device side only transmit the first type of signal in the active period indicated by the DRX configuration, and not transmit the first type of signal in the inactive period, which is also called as a signal that the DRX configuration can manage. And for the second type of signal, it can be considered as a signal that is not affected by the DRX configuration.

Specifically, in the present embodiment, the transmission/reception state of the first signal includes any one of the following transmission/reception states: transmitting, receiving, not transmitting, not receiving. Wherein the transmitting includes any one of: transmitting target Discontinuous Reception (DRX) configuration information configured for the terminal equipment based on the base station, transmitting based on RRC configuration information, and transmitting based on dynamic scheduling information; and the receiving includes any one of the following: the reception is performed based on the target DRX configuration information, the reception is performed based on the RRC configuration information, and the reception is performed based on the dynamic scheduling information.

It should be understood that when the first signal is an uplink signal, for the access network device, it means to receive the first signal, and for the terminal device, it means to transmit the first signal; when the first signal is a downlink signal, it means to transmit the first signal for the access network device and to receive the first signal for the terminal device.

In this embodiment, the network device indicates one mode (i.e., the first mode) to the terminal device through the first information. In this embodiment, the first mode is one of a plurality of modes, and the transmission and reception states of the first signal indicated by different modes in the plurality of modes are different. In a specific implementation, the first information may be set to different values so that the indicated first mode is different, so that the transmission and reception states of the indicated first signals are different, or in other words, when the contents of the first information transmitted to the terminal device are different, the indicated first mode is different.

In this embodiment, the modes indicated by the terminal device may include the following modes, and the first mode is any one of the following modes:

first mode: the first signal is indicated to comprise a first group of signals, a second group of signals, a third group of signals and a fourth group of signals, and the receiving and transmitting state of the first signal is that the terminal equipment transmits and receives based on RRC configuration information or dynamic scheduling information.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access device sends the first set of signals and the third set of signals based on RRC configuration information or dynamic scheduling information, and receives the second set of signals and the fourth set of signals based on RRC configuration information or dynamic scheduling information; accordingly, the terminal device receives the first and third sets of signals based on the RRC configuration information or the dynamic scheduling information, and transmits the second and fourth sets of signals based on the RRC configuration information or the dynamic scheduling information.

It should be noted that, in the first mode, if the terminal device is configured with DRX configuration, the access device still transmits the first set of signals and the third set of signals based on RRC configuration information or dynamic scheduling information; accordingly, the terminal device still receives the first set of signals and the third set of signals based on the RRC configuration information or the dynamic scheduling information. That is, in the first mode, if the terminal device is configured with the DRX configuration, the DRX configuration is also ignored (i.e., the DRX configuration fails for the first type of signal, and the first type of signal is no longer transmitted or received according to the DRX configuration), but is based on the transceiving state of the first signal indicated by the first mode.

It can be further understood that in the first mode, the access network device may perform aggregate scheduling, and when the traffic load is relatively light, since the traffic of each terminal device may tolerate a certain delay, the access network device may aggregate all signals together after scheduling is completed, and enter deep sleep in a later period.

Second mode: the first signal is indicated to comprise the first set of signals, the second set of signals, the third set of signals and the fourth set of signals, and the receiving and transmitting states are that the terminal equipment does not receive and does not transmit.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access network device does not send the first set of signals and the third set of signals, and does not receive the second set of signals and the fourth set of signals; accordingly, the terminal device does not receive the first and third sets of signals and does not transmit the second and fourth sets of signals.

It should be noted that, in the first mode, if the terminal device is configured with the DRX configuration, the access device still does not send the first set of signals and does not receive the second set of signals; accordingly, the terminal device still does not receive the first set of signals and does not transmit the second set of signals. That is, in the first mode, if the terminal device is configured with the DRX configuration, the DRX configuration is also ignored (i.e., the DRX configuration fails for the first type of signal, and the first type of signal is no longer transmitted or received according to the DRX configuration), but is based on the transceiving state of the first signal indicated by the first mode.

It will also be appreciated that in this first mode the access network device has switched off all signals, so that the access network device can go deep sleep, and that after informing the terminal device, the terminal device can also go deep sleep.

Third mode: the first signal is indicated to comprise a third set of signals and a fourth set of signals, and the receiving and transmitting states are that the terminal equipment does not receive and does not transmit.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access network device sends the first set of signals and sends and receives the second set of signals, and does not send the third set of signals and does not receive the fourth set of signals based on the target DRX configuration information; accordingly, the terminal device receives the first set of signals and transmits the second set of signals based on the target DRX configuration information, and does not receive the third set of signals and does not transmit the fourth set of signals.

It will also be appreciated that in this first mode the access network device turns off signals that are not affected by the DRX configuration, such that the terminal device may only transmit or receive signals for the active period indicated by the DRX configuration and may sleep for the inactive period, and accordingly the access network device may also be put to sleep for the inactive period or the access network device may still wake up from the inactive period.

Fourth mode: the first signal is indicated to comprise a first set of signals and a second set of signals, and the transceiving state is that the terminal equipment does not receive and does not transmit.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access network device does not send the first set of signals and does not receive the second set of signals, and sends the third set of signals and receives the fourth set of signals based on RRC configuration information or dynamic scheduling information; accordingly, the terminal device does not receive the first set of signals and does not transmit the second set of signals, and receives the third set of signals and transmits the fourth set of signals based on the RRC configuration information or the dynamic scheduling information.

It should be noted that, in the first mode, if the terminal device is configured with the DRX configuration, the access device still does not send the first set of signals and does not receive the second set of signals; accordingly, the terminal device still does not receive the first set of signals and the third set of signals. That is, in the first mode, if the terminal device is configured with the DRX configuration, the DRX configuration is also ignored (i.e., the DRX configuration fails for the first type of signal, and the first type of signal is no longer transmitted or received according to the DRX configuration), but is based on the transceiving state of the first signal indicated by the first mode.

It may also be appreciated that, in the first mode, the access network device turns off the first type of signal that is originally affected by the DRX configuration, so that, after the first mode is turned off, if there is no signal transmission or reception of other static configurations, only dynamic signals are generated, and when there is no actual service, both the access network device and the terminal device may go to bidirectional deep sleep, or else they may wake up periodically according to the DRX configuration.

Fifth mode: the indication first signal comprises a first set of signals, a second set of signals, a third set of signals and a fourth set of signals, and the receiving and transmitting states are that the terminal equipment receives and transmits based on the target DRX configuration information.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access network device sends the first set of signals and the third set of signals based on the target DRX configuration information, and receives the second set of signals and the fourth set of signals based on the target DRX configuration information; accordingly, the terminal device receives the first and third sets of signals based on the target DRX configuration information, and transmits the second and fourth sets of signals based on the target DRX configuration information.

It is further understood that in this first mode, the access network device turns off the signal of the second type, which was not originally affected by the DRX configuration, that is being transmitted and received at all times, into a signal that is transmitted and received based on the DRX configuration. In this way, since the second type of signal is turned off to be a signal that is transmitted and received based on the DRX configuration, the terminal device and the access network device can truly implement periodic dormancy based on the DRX configuration.

Sixth mode: the first signal comprises a first group of signals and a second group of signals, and the receiving and transmitting state is that the terminal equipment receives the first group of signals and transmits the second group of signals based on the target DRX configuration information.

It can be understood that, when the transceiving state of the first signal indicated by the first mode is such a case, the access network device sends the first set of signals and receives the second set of signals based on the target DRX configuration information, and sends the third set of signals and receives the fourth set of signals based on the RRC configuration information or the dynamic scheduling information; accordingly, the terminal device receives the first set of signals and transmits the second set of signals based on the target DRX configuration information, and receives the third set of signals and transmits the fourth set of signals based on the RRC configuration information or the dynamic scheduling information.

It is to be noted that the above six modes are merely examples, and do not constitute limitations of the present application. For example, in implementations, further modes may be provided, where the further modes are for example only active on downstream signals (i.e. comprising a first set of signals and a third set of signals); alternatively, the further pattern may for example only act on upstream signals (i.e. comprising a second set of signals and a fourth set of signals) etc.

In the signal transmission method provided by the application, the access network equipment indicates the receiving and transmitting state of the first signal by sending the first information to the terminal equipment, so that the receiving and transmitting states between the access network equipment and the terminal equipment are kept consistent, a precondition is provided for the access network equipment and the terminal equipment to enter deep sleep, and the access network equipment and the terminal equipment are facilitated to realize deep sleep so as to further reduce power consumption.

As an alternative embodiment, when the application is implemented, the access network device may send the first information by multicast or broadcast. That is, the access network device only transmits PDCCH or PDSCH on a certain time-frequency resource, and then all terminal devices receive PDCCH or PDSCH on the same time-frequency resource, and obtain the first mode indicated by the respective corresponding access network device.

In a first possible embodiment, the first information sent by the network device may comprise a plurality of bits, which may then simultaneously indicate a plurality of terminal devices.

As shown in fig. 4, it is assumed that the first information is composed of two bits, the two bits may indicate 4 different states, and the value of the first bit is 0, and the value of the second bit is 0, then when the terminal device 1 receives the first information, it may be determined that the access network device indicates the mode 1, and when the terminal device 2 receives the first information, it may be determined that the access network device indicates the mode 4, then the terminal device 1 may determine the transmission and reception state of the first signal based on the mode 1, and the terminal device 2 may transmit based on the transmission and reception state of each signal in different signals corresponding to the mode 4. It can be seen that in this indication mode, the same first information may indicate the same mode or different modes for different terminal devices.

In a second possible embodiment, the first information may include a plurality of bits, and different bits correspond to different terminal devices, and different values of bits corresponding to the respective terminal devices indicate different modes. Illustratively, fig. 5 is a schematic structural diagram of an indication manner provided in another embodiment of the present application. Fig. 5 illustrates 3 terminal devices as an example. As shown in fig. 5, the terminal device 1 corresponds to a first bit and a second bit in the first information, the terminal device 2 corresponds to a third bit and a fourth bit in the first information, and the terminal device 3 corresponds to a fifth bit and a sixth bit in the first information. Then, after the access network device sends the first information, when the terminal device 1 receives the first information, it can be determined that the network device indicates the mode 1, and when the terminal device 2 receives the first information, it can be determined that the network device indicates the mode 2; and when the terminal device 3 receives the first information, it can be determined that the network device indicates mode 3.

As an alternative embodiment, the above-mentioned non-reception or non-transmission of the first signal means that the first signal is triggered by the first information for a period of time.

In a specific implementation, when the terminal device receives the first information after receiving the first information for a period of time, the terminal device receives the first information again, and in this case, the terminal device and the access network device communicate based on a new mode indicated by the new first information (i.e. the indicated receiving and transmitting state of the new first signal). For example, the first information sent by the access network device to the terminal device indicates the second mode described in the embodiment shown in fig. 3, after a period of time, the access network device sends new first information to the terminal device, where the new first information indicates the fifth mode described in the embodiment shown in fig. 3, and after receiving the new first information, the terminal device communicates with the access network device based on the transceiving state of the first signal indicated by the fifth mode.

In a specific implementation, the access network device may further send RRC signaling to the terminal device, where the RRC signaling carries information indicating a first period of time, where the first period of time indicates a duration of a transceiving state of the first signal. In this embodiment, when the access network device sends the first information to the terminal device, the timing is started, and after the time exceeds the duration indicated by the first period, the default mode is returned. Optionally, the default mode is that the first type of signal is received or transmitted based on the DRX configuration, and the second type of signal is received or transmitted based on the RRC configuration information or the dynamic scheduling information.

It should be noted that, in this application, the first information should not be affected by the DRX configuration. That is, even in the inactive period of the DRX configuration indication, the first information transmitted by the access network device may be received by the terminal device.

Alternatively, in the present application, when the first information indicates the transmitting/receiving state of the first signal, the first signal may be a signal on the Pcell or a signal on the Scell, which does not constitute a limitation of the present application.

Optionally, in this application, after the terminal device receives the first information and determines the state of receiving and transmitting the first signal according to the first mode, the time when the terminal device actually enters the state of receiving and transmitting the first signal in the first mode (i.e. the effective time) may be: when the terminal equipment processes the PDCCH or the PDSCH; or after the terminal equipment processes the PDCCH or PDSCH and sends the ACK or NACK to the access network equipment; or, an effective time based on the higher layer signaling configuration; or, running the DRX timer already running in the configured target DRX configuration; or, it takes effect immediately, turning off all running DRX timers.
