The DRX is dedicated to the terminal, that is, the network device needs to be configured separately for each terminal device, and the DRX configuration of different terminal devices may be different, resulting in a large signaling overhead for DRX configuration.

Detailed ways

In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments.

In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

(1) SSB

SSB includes primary synchronization signals (primary synchronization signals, PSS), secondary synchronization signals (secondary synchronization signals, SSS), physical broadcast channel (physical broadcast channel, PBCH). The PSS/SSS is mainly used for downlink synchronization of terminal equipment and obtaining cell identification (identification, ID). Downlink synchronization includes clock synchronization, wireless frame synchronization, and symbol synchronization. The PBCH carries the master information block (MIB), which includes system frame number (system frame number, SFN), subcarrier spacing, scheduling system information (system information, SI) PDCCH configuration and other information.

(2)PRACH

During the random access process of the terminal device, the network device needs to configure the PRACH for the terminal device to access the system. Since the movement of the terminal equipment makes the distance between the terminal equipment and the network equipment uncertain, if the terminal equipment needs to send a message to the base station, it must maintain and manage uplink synchronization in real time. The purpose of PRACH is to achieve uplink synchronization, establish a relationship between terminal equipment and network equipment for uplink synchronization, and request network equipment to allocate dedicated resources to terminal equipment, so that terminal equipment can normally access network equipment for service transmission.

(3) Wireless network temporary identifier (information-radio network temporary identifier, RNTI)

RNTI is used to differentiate or identify connected terminal devices in a cell, a specific radio channel, a group of terminal devices in case of paging, a group of terminal devices receiving power control parameters, system information sent by network equipment for all terminal devices. RNTI can be a 16-bit identifier whose value depends on the type of RNTI. The RNTI used for paging is denoted as P-RNTI. In addition, there are cell radio network temporary identifier (C-RNTI) for data scheduling, modulation and coding scheme cell radio network temporary identifier (MCS-C) -RNTI), configured scheduling radio network temporary identifier (configured scheduling radio network temporary identifier, CS-RNTI), etc.

(4) DRX mechanism

The terminal device monitors the PDCCH to check whether there is DCI from the serving cell, so as to perform signal transmission with the network device. In many cases, the terminal device does not always perform effective information interaction with the network. At this time, if the terminal device continuously monitors the PDCCH, the power consumption will be relatively large. In order to save the power consumption of terminal equipment and ensure the effective transmission of data, NR introduces the DRX mechanism. The DRX mechanism can also be understood as the DRX mechanism of terminal equipment. Through the DRX mechanism, terminal equipment can periodically monitor PDCCH in certain time periods. , and do not monitor the PDCCH in other time periods, so as to realize energy saving of the terminal equipment.

An example of the DRX mechanism shown in Figure 1, the DRX mechanism involves the following parameters: DRX long cycle start offset drx-LongCycleStartOffset, DRX time slot offset drx-SlotOffset and DRX activation duration drx-onDurationTimer. Among them, drx-LongCycleStartOffset is used to configure the time window of long-cycle DRX (Long DRX cycle), including the length P of each time window (also called DRX period), and the start subframe offset S _sf , which can be expressed in sub The frame (subframe) is the unit; drx-SlotOffset is used to configure the start time slot offset value S time _slot within the duration (on Duration) of the start subframe, which can be counted in units of time slot (Slot); drx -onDurationTimer is used to configure the duration T ₁ of the onDuration from the starting moment, and the unit may be milliseconds (ms). The terminal device enters an active time (Active Time) at the start time of the start time slot of the start subframe of each time window. Until the end of the on Duration, the terminal device enters the inactive time (Inactive Time). The activation time may also be referred to as an activation period, an activation time period, etc., and the terminal device is in an activated state within the activation time. The inactive time may also be referred to as an inactive time period, an inactive period, etc., and the terminal device is in an inactive state during the inactive time.

When the terminal device is configured with the DRX mechanism, the terminal device first enters the activation time/On Duration when each DRX cycle arrives, and starts the DRX duration timer (drx-onDurationTimer). After the DRX duration timer expires, the terminal device will enter the inactive time; if the PDCCH for scheduling data transmission is detected during the On Duration period, the terminal device starts or restarts the DRX inactivity timer (drx-InactivityTimer), and the DRX inactivity timer runs , the terminal device is within the activation time.

The DRX mechanism has two cycle configurations, Long DRX cycle and Short DRX cycle, as shown in Figure 2. After the drx-InactivityTimer ends or the terminal device receives the DRX command (DRX Command) media access control channel element (media access control channel element, MAC CE), after the drx-InactivityTimer ends or the DRX Command MAC CE receives the first The symbol starts the drx-ShortCycleTimer. During the running of the timer, the UE enters the Short DRX cycle state, that is, the onDuration is determined according to the Short DRX cycle; when the drx-ShortCycleTimer ends, the UE enters the Long DRX cycle state, that is, the onDuration is determined according to the Long DRX cycle.

The terminal device can re-enter the Short DRX Cycle after each drx-InactivityTimer ends; when no data arrives for a continuous period of time, it can switch to the Long DRX cycle. In addition, the base station can be forced to enter the Short DRX cycle through the DRX Command MAC CE, or it can be forced to enter the Long DRX cycle through the Long DRX Command MAC CE.

(5) Dis-continuous transmission (DTX) mechanism

In order to further reduce the power consumption of the communication device, the communication device may be enabled not to send data transmission for a period of time, or the communication device may be enabled not to send all or part of the channels for a period of time. This way of reducing power consumption of communication devices may be called a DTX mechanism.

Due to the interactive nature of the communication system, DTX has different interpretations for two or more communication devices communicating. For a sending device, DTX can be understood as a discontinuous transmission mechanism, and for a receiving device corresponding to a sending device configured with DTX, the receiving device at this time can be understood as a discontinuous receiving mechanism in DTX. For ease of description, DTX in this application refers to the cell-level discontinuous transmission mechanism. Since network devices can communicate with multiple terminal devices in the cell, for the convenience of description, cell-level DTX in this application can also be understood as network device DTX Mechanism, through the network equipment DTX mechanism, can realize the energy saving of the network equipment.

For example, a network device can set a transmission pattern, and only perform data transmission in a part of the time period in a transmission cycle, and do not perform data transmission and reception in other time periods.

When there is no business load, the network device DTX mechanism can be used to reduce the power consumption of the network device.

When the business load is very light, although there are data transmissions in many transmission time intervals, the resource utilization rate of the transmission time intervals is very low. At this time, the DTX mechanism of the network device can also be used to collect the data to be sent into the time period A In this way, the DTX state can be entered in the time period B, and the static energy saving of the network equipment can be realized.

6) SPS PDSCH occasion (SPS PDSCH occasion)

The network device configures semi-persistently scheduled downlink data transmission through RRC signaling. That is, in each period, the PDSCH is sent on a fixed time-frequency resource. Each time-frequency resource is called an SPS PDSCH occasion, which can be interpreted as a sending opportunity, indicating that the time-frequency resource can be used to carry and send downlink data. The SPS PDSCH occasion can be configured and activated through RRC signaling, or it can be configured through RRC signaling and activated through DCI after RRC signaling configuration.

In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And/or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone, where A, B can be singular or plural. The character "/" generally indicates that the contextual objects are an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one item (piece) of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

And, unless otherwise stated, the ordinal numerals such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects, and are not used to limit the size, content, order, and timing of multiple objects , priority or importance, etc. For example, the first parameter and the second parameter are only used to distinguish different parameters, and do not mean that the content, value, priority or importance of the two parameters are different.

The communication system applied in the embodiment of the present application is introduced above, and the technical features involved in the embodiment of the present application are introduced below.

According to the terminology introduction 4) above, it can be seen that the DRX mechanism is more from the perspective of terminal equipment energy saving. It configures the time period for terminal equipment to receive downlink control information and the time period for terminal equipment not to receive downlink control information. At the same time, the terminal equipment DRX mechanism It is based on the independent configuration of each terminal device. Therefore, the DRX mechanism brings a large signaling overhead to the network device and has little effect on energy saving of the network device. Moreover, the terminal device still needs to receive some information or channel transmission during the inactive period, and DRX needs to be improved in realizing energy saving of the terminal device. Therefore, an embodiment of the present application provides an energy saving method, which saves power consumption of terminal devices and network devices by configuring a cell-level discontinuous transmission mechanism.

Based on this, embodiments of the present application provide a communication method and device, which save power consumption of terminal equipment and network equipment by configuring a cell-level discontinuous transmission mechanism. Wherein, the method and the device are based on the same idea, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

As shown in FIG. 4 , it is a schematic flowchart of a communication method provided by the embodiment of the present application.

S401. The network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

Wherein, the first information is used to indicate the first time window. The first time window is a time window in which the network device and the terminal device do not transmit the first channel.

The first information is at the cell level. It can be understood that the first information is carried in signaling or channels at the cell level. Alternatively, it can be understood that the first information is cell-specific information, that is, the first information is not specific to a specific terminal device. Or it can also be understood that the first information is sent by the network device to all terminal devices in the cell, and the first information received by all the terminal devices in the cell is the same first information.

For example, the first information may be broadcast information, carried by a broadcast channel, or scrambled by a common RNTI. Since the first information is cell-level information, and the first information indicates the first time window, it can also be understood that the first information indicates the first time window to all terminal devices in the first cell.

Alternatively, the first information is used to indicate the first time window for a group of terminal devices, for example, the first information may be multicast information.

Example 1. The first information implicitly indicates the first time window. For example, the first information is used to configure the DTX mechanism of the network device. The DTX mechanism of the network device corresponds to the first time window. The network device indicates the first time window to the terminal device by indicating the DTX mechanism of the network device. Time Window.

Example 2, the first information explicitly indicates the first time window, for example, at least one of the start time, duration, or end time when the first information passes through the first time window indicates the first time window. Compared with Example 1, Example 2 can also be understood that at this time the first information does not configure the DTX mechanism, but only indicates a period of time as the first time window.

The manner in which the first information indicates the first time window in Example 1, that is, the manner in which the first information configures the DTX mechanism of the network device, the specific description of the first channel, and the sending manner of the first information will be described in detail below.

S402. The terminal device does not transmit the first channel within the first time window according to the first information. Correspondingly, the network device does not transmit the first channel within the first time window.

In the following, firstly, the manner in which the first information in Example 1 in S401 indicates the first time window, that is, the manner in which the first information configures the network DTX mechanism, is exemplarily described.

For example, the first time window is a period of time within the first cycle, and the first information may indicate at least one of the following: the first cycle, the first on time, the first off time, the on duration, or the off duration. Wherein, the time unit of the first period may be slot/subframe/frame (frame)/millisecond and so on. The first period may include one or more first time windows, and may further include one or more second time windows, where the second time window is a time window in which the network device and the terminal device can transmit the first channel.

The first opening time is the start time when the terminal device can transmit the first channel in the first period, and it can also be understood as the start position or start time of the second time window. Exemplarily, the first turn-on time may be an offset relative to the starting position of the first period. For example, the first period is a frame or subframe, and the first opening time may indicate a slot in the frame or subframe. Or if the first period is a slot/subslot (subslot), the first on time may indicate a symbol within a slot/subslot period.

The first closing time is the starting moment when the terminal device stops transmitting the first channel in the first period, and may also be understood as the starting position or starting moment of the first time window. Exemplarily, the first closing time may be an offset relative to the starting position of the first period. For example, the first cycle is a frame/subframe, and the first closing time may indicate a slot in the frame/subframe. Or if the first period is a slot/subslot, the first off time may indicate a symbol within a slot/subslot period.

The on-duration is the duration during which the terminal device can transmit the first channel within a period, and may also be understood as the duration of the second time window.

The shutdown duration is the duration during which the terminal device cannot transmit the first channel within a period, and may also be understood as the duration of the first time window.

It should be noted that one or more parameters in the above-mentioned first period, first on time, first off time, on duration, and off duration may be indicated by the first information, or may be predefined, such as protocol-specified, or pre-configured, etc. One or more parameters in the first period, the first opening time, the first closing time, the opening duration, and the closing duration can also be part of the parameters by the first indication information, and other part of the parameters are predefined or preconfigured.

In one example, the first period includes a second time window. The first information may indicate a first period, where the duration of the first period is P1 _, the first turn-on time S and the turn-on duration T. The second time window can be determined according to the first opening time and the opening duration, so that the first time window can be determined according to the first cycle and the second time window, wherein the first time window is a time outside the second time window in the first cycle part. As shown in Figure 5.

In another example, the first period includes multiple second time windows. The first information may indicate the first period, the opening time of each second time window, and the opening duration of each opening time period. Taking the first period including two second time windows as an example, the first information may indicate the first period, where the duration of the first period is P _{1 ,} the first opening time (S ₁ ), and the first opening duration (T1), the second first turn-on time (S ₂ ) and the second turn-on duration (T2). The first second time window can be determined according to the first first opening time and the first opening duration, and the second second time window can be determined according to the second first opening time and the second opening duration, Therefore, the first time window is determined according to the first cycle and the two second time windows, wherein the first time window is a time period in the first cycle other than the two second time windows. As shown in Figure 6.

In addition to the first opening time and the first closing time, the network device instructs to apply the second opening time when the first condition is met. And/or, when the second condition is met, the network device instructs to apply the second closing time. It should be noted that the second on time and/or the second off time may be indicated by the network device. The application may also be determined by the terminal device, for example, the second on time is applied when the first condition is met, and the second off time is applied when the second condition is met. Optionally, in an embodiment where the terminal device determines to apply the second on time and/or the second off time, the second on time and/or the second off time may be indicated by the network device or may be defined by a protocol. The first condition and/or the second condition may be indicated by a network device, or may be defined by a protocol.

Wherein, the second closing time is associated with the second condition, that is, the second closing time takes effect when the second condition is met. The foregoing second off time may correspond to an off timer, and the terminal device and the network device do not transmit the first channel during the timing of the off timer. The second closing time is associated with the second condition, which can be understood as triggering the closing timer when the second condition is met.

Wherein, when the second condition is satisfied, the second off time may override the first on time, and it may also be understood that the priority of the second off time is higher than that of the first on time. That is, at a moment within the second time window, if the second condition is not met, the terminal device and the network device can transmit the first channel, but since the second condition is met at this time, the second off-time corresponding off-timer is started , so during the timing of the off timer, the terminal device and the network device do not transmit the first channel until the off timer ends. After the closing timer ends, the first channel can be transmitted according to the second time window. Specifically, if the closing timer is still within the second time window after the closing timer ends, the first channel can be transmitted within the remaining time of the second time window. channel until the end of the second time window. If the closing timer is not located in the second time window, that is, in the first time window, the first channel cannot be transmitted until the next second time window is entered, and the second channel can be transmitted in the next second time window. one channel.

The second opening time is associated with the first condition, that is, the second opening time becomes effective when the first condition is met. The above-mentioned second opening time may correspond to an opening timer, and the terminal device and the network device may transmit the first channel during the timing of the opening timer. The second start time is associated with the first condition, which can be understood as triggering the start timer when the first condition is met.

Wherein, when the first condition is satisfied, the second on time may override the first off time, and it can also be understood that the priority of the second on time is higher than that of the first off time. That is, at a certain moment in the first time window, if the first condition is not satisfied, the terminal device and the network device cannot transmit the first channel, but because the first condition is satisfied at this time, the opening timing corresponding to the second opening time is started Therefore, during the timing of the on-timer, the terminal device and the network device can transmit the first channel until the on-timer ends. The first channel may not be transmitted according to the first time window after the start timer expires. Specifically, if the start timer is still within the first time window after the end of the timer, the first channel cannot be transmitted within the remaining time of the first time window until the end of the first time window. If the start timer is not located in the first time window, that is, in the second time window, the first channel can be transmitted until the next first time window is entered, and the second channel cannot be transmitted in the next first time window. one channel.

This application is not limited to only one off timer (or second off time) and/or on timer (or second on time), and there may be multiple off timers and/or multiple on timers in specific embodiments. Timers, and the conditions associated with any two open timers can be different, and the conditions associated with any two closed timers can be different.

For ease of understanding, an example is given here. For example, a second start time may be defined, and the second start time corresponds to start timer 1, and the start timer 1 may be called dtx-InactivityTimer. The condition corresponding to the start timer 1 (that is, the first condition associated with the second start time) is that at the end of the second time window, the transmission of the first channel has not yet ended, for example, the transmitted data packet is relatively large, and at the second time window The transfer was not complete when the window ended. However, this data packet may be more important and needs to be completely transmitted. At this time, timer 1 can be started to force the network device and terminal device to complete the transmission. As shown in FIG. 7 , assuming that there is still data to be transmitted at the end of the second time window, the start timer 1 is started, and the terminal device and the network device can transmit the first channel before the start timer 1 ends.

The above describes the network device DTX mechanism. The first channel is introduced below.

Exemplarily, the first channel includes a first uplink channel and/or a first downlink channel. The first channel will be described below.

For example, the first channel may include at least one of the following types: a first group of channels, a second group of channels, a third group of channels, or a fourth group of channels;

Wherein, the first group of channels may be signals related to data transmission, and may also be understood as signals transmitted after the RRC connection is established. For example, the first group of channels includes at least one of the following signals: SPS PDSCH, CG PUSCH, HARQ-ACK for SPS PDSCH, SR, or BFR. That is, the first uplink channel includes at least one of the following signals: CG PUSCH, HARQ-ACK for SPS PDSCH, BFR, or SR, and the first downlink channel includes the following signal: SPS PDSCH.

Since the time domain resources for transmitting SPS PDSCH are configured in advance, some or all of the time domain resources for transmitting SPS PDSCH may be located in the first time window, resulting in the failure of PDSCH to pass through the time domain resources configured in advance. transmission.

For this problem, two possible solutions are given below.

Solution 1: The transmission of the SPS PDSCH can be delayed, for example, the transmission of the SPS PDSCH can be delayed until the next on-time period (next second time window).

Optionally, when the transmission of the SPS PDSCH is delayed, it can be sent through a new dynamically scheduled (dynamic grant, DG) PDSCH or a new SPS PDSCH occasion. Because when transmitting SPS PDSCH in the second time window, there may be no SPS PDSCH transmission opportunity, and no corresponding time-frequency resources are available (such as corresponding time-frequency resources are occupied by other signals in advance), and there may also be multiple SPS PDSCHs. In the case of delayed transmission, the above method sends SPS PDSCH through the new DG PDSCH or new SPS PDSCH occasion, which can improve the transmission reliability of SPS PDSCH.

Solution 2: similar to the solution of applying the second opening time. That is, when the SPS starts to transmit, or when the second time window ends, an on timer is started, and the SPS PDSCH can be transmitted during the timing of the on timer. Or it can be understood that during the timing of the on-timer, the second on-time is applied and the activation state is maintained, so as to complete the transmission of the entire SPS PDSCH. A possible scenario is that the transmission of the SPS PDSCH starts within the second time window, but the transmission has not been completed at the end of the second time window.

Since the time domain resources for transmitting HARQ-ACK for SPS PDSCH are also configured in advance, some or all of the time domain resources for transmitting HARQ-ACK for SPS PDSCH may be located in the first time window, causing HARQ - ACK message could not be transmitted. For this problem, three possible solutions are given below.

Solution A: HARQ-ACK for SPS PDSCH can be sent together with the HARQ-ACK feedback of a dynamically scheduled PDSCH, that is, HARQ-ACK for SPS PDSCH can be sent on the time domain resource corresponding to the HARQ-ACK feedback of the dynamically scheduled PDSCH Sending, or, can also be understood as sending the HARQ-ACK feedback of the HARQ-ACK for SPS PDSCH and the dynamically scheduled PDSCH through the same uplink channel. In this method, the transmission behavior of HARQ-ACK for SPS PDSCH can follow the transmission of HARQ-ACK of dynamically scheduled PDSCH to ensure the reliability of HARQ-ACK transmission.

Since the dynamic scheduling is more flexible and timely, if the time domain resources corresponding to the HARQ-ACK feedback of the dynamically scheduled PDSCH are within the first time window, the network device can timely schedule the transmission of the HARQ-ACK feedback within the second time window, so that The HARQ-ACK feedback of PDSCH is transmitted in time. In the embodiment of the present application, by sending the HARQ-ACK for SPS PDSCH together with the HARQ-ACK feedback of the dynamically scheduled PDSCH, the HARQ-ACK for SPS PDSCH can be sent in time to improve the communication performance.

Scheme B: If part or all of the time domain resources of the HARQ-ACK for SPS PDSCH can be located in the first time window, the HARQ-ACK for SPS PDSCH may not be fed back. Alternatively, the terminal device does not expect the SPS PDSCH to be transmitted within the second time window but the corresponding HARQ-ACK is transmitted within the first time window, and the network device can configure the HARQ-ACK feedback when configuring the transmission time and period of the SPS PDSCH in the second time window. Alternatively, the second on-time is started by the first condition, that is, the on-timer corresponding to the second on-time is started.

Scheme C: HARQ-ACK for SPS PDSCH can be delayed until the next second time window for transmission. Specifically, the sending may be delayed until the uplink time slot of the next second time window. Optionally, the network device can also configure the maximum delay time of HARQ-ACK for SPS PDSCH. If the delay of HARQ-ACK for SPS PDSCH exceeds the maximum delay time, then this HARQ-ACK for SPS PDSCH can no longer be transmitted.

If the sending time of CG PUSCH and SR is within the first time window, the terminal device can delay sending CG PUSCH and SR, for example, it can be delayed until the next opening time period (the next second time window). Alternatively, the second turn-on time may also be started, and a corresponding turn-on timer may be started, and the CG PUSCH and SR may be transmitted during the timing of the turn-on timer.

For BFR, the terminal device may not perform BFR measurement and update within the first time window. Correspondingly, the network device may not send the BFR measurement signal.

The second group of channels may be access-related signals, and may also be understood as signals transmitted before the RRC connection is established. For example, the second group of channels includes at least one of the following signals: PDCCH scrambled by SI-RNTI, PRACH, PDCCH scrambled by RA-RNTI, or PDCCH scrambled by TC-RNTI. That is, the first uplink channel includes at least one of the following signals: PRACH, HARQ-ACK for SPS PDSCH, BFR, or SR, and the first downlink channel includes at least one of the following signals: SI-RNTI scrambled PDCCH, RA-RNTI scrambled PDCCH, or TC-RNTI scrambled PDCCH.

Optionally, for the PDCCH scrambled by SI-RNTI: if SIB1 is also scrambled by SI-RNTI, when the terminal device does not receive the first information, blind detection may be performed on SIB1. After receiving the first information, the terminal device may receive the PDCCH scrambled by the SI-RNTI according to the period configured by the first information. After sending the first information, the network device may send the PDCCH scrambled by the SI-RNTI according to the period configured by the first information.

For the PRACH and the PDCCH scrambled by the RA/TC-RNTI: after receiving the first information, the terminal device does not send the PRACH or detect the PDCCH scrambled by the RA/TC-RNTI within the first time window.

A third group of channels may be paging signals. For example, the third group of channels includes: PDCCH scrambled by P-RNTI. That is, the first downlink channel includes the PDCCH scrambled by the P-RNTI.

Optionally, the time domain position of the PDCCH scrambled by the P-RNTI is not within the first time window. Alternatively, it may also be described as the time-domain position of the PDCCH scrambled by the P-RNTI in the first time window. The specific implementation form may be that when the network device configures paging transmission, the configuration of the paging period is associated with the configuration of the gNB DTX period.

The fourth group of channels includes: SSB. That is, the first downlink channel includes SSB.

At present, the DRX mechanism of the terminal device is invalid for signals such as SSB, PRACH, SR, and BFR, that is, the terminal device still transmits signals such as SSB, PRACH, SR, and BFR during DRX inactivation time. As a result, the power consumption of the terminal equipment is still relatively large. In the embodiment of the present application, the terminal device may not transmit the foregoing signal within a period of time (ie, the first time window) according to the first information, thereby further saving power consumption of the terminal device.

The type of the first channel is introduced above, and several possible examples are given below in combination with the type of the first channel and the manner of sending the first information.

Example A, the first information may be carried in SIB1. In this example A, the first channel may include at least one group of channels from the first group of channels to the third group.

In the above example A, if the first information is carried in SIB1, the first channel may include at least one group of channels from the first group of channels to the third group of channels. That is, if the terminal device receives the first information in SIB1, it does not transmit at least one group of channels in the first group of channels to the third group of channels within the first time window.

Alternatively, the foregoing example A may also be understood as, if the first channel includes at least one group of channels from the first group of channels to the third group of channels, the first information may be carried in SIB1. That is, if the network device instructs the terminal device not to transmit at least one group of channels from the first group of channels to the third group of channels within the first time window, the first information may be sent through SIB1.

Since signaling such as PRACH is sent before the initial access of the terminal device, and the RRC connection has not been established at this time, the network device can control the transmission of signaling such as PRACH before establishing the RRC connection by sending the first information through SIB1.

Example B, the first information may be carried in RRC signaling. In this example B, the first channel may include the first group of channels and not include the second group of channels and/or the third group of channels.

In the above example B, if the first information is carried in the RRC signaling, the first channel may include the first group of channels and not include the second group of channels and/or the third group of channels. That is, if the terminal device receives the first information in the RRC signaling, it does not transmit the above-mentioned first group of channels within the first time window, and transmits the second group of channels and/or the third group of channels.

Alternatively, the above example B may also be understood as, if the first channel includes the first group of channels, the first information may be carried in the RRC signaling. That is, if the network device instructs the terminal device not to transmit the first group of channels within the first time window, but may transmit the second group of channels and/or the third group of channels.

Example C, the first channel may not include the SSB, that is, the SSB will always be transmitted. Since SSB is used for synchronization in the cell and broadcast of system messages, as well as for cell selection and measurement of terminal equipment, in order to ensure the normal access of traditional terminal equipment, SSB retains the normal transmission mode and will not be affected by the DTX mechanism. . Since the SSB involves the terminal device accessing the network device, in this example C, it is expected that the SSB can still be transmitted in the mechanism provided by this application.

In the above examples A to C, sending the first information through cell-level signaling can realize the unified configuration of the first time window to the terminal devices in the cell. , so that the signaling overhead can be reduced.

In an implementation manner, the default communication behavior of the terminal device within the first time window is not to transmit the first channel. Therefore, the terminal device does not transmit the first channel within the first time window after receiving the first information.

Wherein, the type of the first channel may be default, or may be indicated by the network device, or may be determined according to the signaling carrying the first information, and the communication between the signaling carrying the first information and the first channel For the corresponding relationship, reference may be made to the above description, which will not be repeated here.

The manner of sending the first information and the corresponding communication behavior of the terminal device have been exemplarily described above in combination with the type of the first channel.

In a possible scenario, the embodiment shown in FIG. 4 may further include S403 (not shown in FIG. 4 ): the network device sends the second information to the terminal device, and the terminal device receives the second information from the network device accordingly. .

The second information is used to indicate whether the first time window is valid. Therefore, the terminal device may not transmit the first channel within the first time window when the second information indicates that the first time window is valid, and may still transmit the first channel when the second information indicates that the first time window is invalid. In a specific implementation manner, the terminal device may receive the second information before transmitting the first channel within the first time window. In another specific implementation manner, the terminal device may receive the second information after not transmitting the first channel within the first time window.

Exemplarily, the second information may be DCI in a first format, and the first format is used to indicate that the first time window is valid. The first format may not be used for other purposes such as scheduling data transmission. Exemplarily, the first format may be the newly added DCI format DCI format 2_Y, that is, the first format may be different from the DCI format type specified in the current protocol, for example, the first format and the DCI type specified in the current protocol include DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, DCI format 2_4, DCI format 2_5, DCI format2_ 6 are all different . In this way, the signaling overhead can be reduced by designing the format of the DCI to implicitly indicate whether the first time window is valid.

Alternatively, the second information may also be scrambled by using the first RNTI, where the first RNTI is used to indicate that the first time window is valid. The first RNTI is not used for other functions, and is different from any RNTI specified in the current protocol. For example, the specified RNTI includes PS-RNTI, P-RNTI and so on.

Optionally, the network device may send the second information within the second time window.

As an example, the second information may only indicate whether the following one or the following N first time windows are valid, where N is an integer greater than 1. N may be a predefined value, or configured by RRC signaling.

In the above manner, if the second information indicates that the first time window is not valid, the terminal device can still transmit the first channel within the first time window. If the second information indicates that the first time window is valid, the terminal device does not transmit the first channel within the first time window. The above method uses additional information to indicate whether the first time window is valid, so that the terminal device and the network device can disable the first time window when the first channel needs to be transmitted when the first information configures the first time window, so that the first time window can be timely The first channel of transmission improves the flexibility of transmission and improves communication performance.

In a possible implementation manner, the embodiment shown in FIG. 4 may further include S404 (not shown in FIG. 4 ): the network device sends information A to the terminal device, and the terminal device receives information A from the network device accordingly.

Information A is used to indicate whether the second time window is valid. Therefore, the terminal device may transmit the first channel within the second time window when the information A indicates that the second time window is valid, or may not transmit the first channel when the information A indicates that the second time window is invalid, such as Figure 8 shows.

Exemplarily, the information A may be DCI in the second format, and the second format is used to indicate that the second time window is valid. The second format may not be used for other purposes such as scheduling data transmission. Exemplarily, the second format may be a newly added DCI format DCI format 2_X, that is, the second format may be different from the DCI format type specified in the current protocol, for example, the first format is the same as the DCI format 0_0 specified in the current protocol, DCI format 0_1, DCI format 0_2, DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, DCI format 2_4, DCI format 2_5, DCI format2_6 are all different. In this way, the signaling overhead can be reduced by designing the format of the DCI to implicitly indicate whether the second time window is valid.

Alternatively, information A may also be scrambled by using a second RNTI, where the second RNTI is used to indicate that the second time window is valid. The second RNTI is not used for other functions, and is different from any RNTI specified in the current protocol. For example, the specified RNTI includes power saving-radio network temporary identifier (PS-RNTI), P-RNTI, etc.

Optionally, the network device may send information A within the first time window.

As an example, the information A may only indicate whether the following one or the following M second time windows are valid, where M is an integer greater than 1. M may be a predefined value, or may be configured by RRC signaling.

In the foregoing manner, if the information A indicates that the second time window is not valid, the terminal device does not transmit the first channel within the second time window. If the information A indicates that the second time window is valid, the terminal device transmits the first channel within the second time window. The above method uses additional information to indicate whether the second time window is valid, so that the terminal device and the network device can disable the second time window when the first channel is not required to be transmitted when the second time window is configured in the first information, so that the second time window can be disabled. Further saving the power consumption of terminal equipment can also improve the flexibility of transmission.

Optionally, the foregoing DTX mechanism may take effect after the terminal device receives the first information. Alternatively, after receiving the first information, the terminal device also needs to determine that the DTX mechanism takes effect according to the instruction of the network device. For example, the network device may send information B to the terminal device, and the information B is used to indicate that the first information takes effect. Optionally, one field/one indication field/one or more bits may be used to carry information B in SIB1 or RRC signaling.

The information B and the first information may be carried in the same signaling, for example, the first information and the information B may be different fields or different indication fields of the same signaling. The first information and the information B may also be carried in different signaling. No specific limitation is made here. If the information B and the first information can be sent in different signaling, the sending method of the information B can be similar to the sending method of the first information. For details, refer to the above example A to example C, and the repetition will not be repeated.

Further, the information B may also indicate the transmission direction corresponding to the effective of the first information, for example, the information B indicates that the first information is effective for the transmission of the uplink channel, or the information B indicates that the first information is effective for the transmission of the downlink channel, or the information B may indicate that the first information is valid for both uplink channel transmission and downlink channel transmission, and so on. The information B will be described below in conjunction with a specific example.

In example D, the information B indicates that the first information is valid for the transmission of the uplink channel, then the terminal device does not send the first uplink channel within the first time window, and the network device does not receive the first uplink channel within the first time window.

In this way, optionally, whether the first information is valid for the transmission of the downlink channel can follow the uplink channel, that is, the terminal device does not send the first uplink channel within the first time window, and does not receive it within the first time window by default. For the first downlink channel, the network device does not receive the first uplink channel within the first time window, and by default does not send the first downlink channel within the first time window.

Example E, information B indicates that the first information is effective for the transmission of the downlink channel, then the terminal device does not receive the first downlink channel within the first time window, and the network device does not transmit the first downlink channel within the first time window, this Therefore, the terminal device does not need to receive the first downlink channel within the first time window. In this way, optionally, whether the first information is valid for the transmission of the uplink channel can follow the downlink channel, that is, the terminal device does not receive the first downlink channel within the first time window, and by default does not receive the first downlink channel within the first time window. To send the first uplink channel, the network device does not send the first downlink channel within the first time window, and by default does not receive the first uplink channel within the first time window.

Example F, information B may indicate that the first information is valid for both the transmission of the uplink channel and the transmission of the downlink channel, then the terminal device does not receive the first downlink channel or send the first uplink channel within the first time window, and the network device The first downlink channel is not sent and the first uplink channel is not received within the first time window.

In the above three examples of example D to example F, the transmission of the uplink channel and the transmission of the downlink channel may be configured simultaneously as one characteristic, or may be configured independently as different characteristics.

In example G, the information B may indicate that the first information is valid for transmission in one direction (such as transmission on an uplink channel or transmission on a downlink channel). Whether the first information is effective for transmission in another direction may be indicated by another information such as information C. In this example, uplink channel transmission and downlink channel transmission can be configured separately as two characteristics, information B and information C can be different fields or different indication fields of the same signaling, or can be composed of two different signaling Carry them separately. For example, there may be two fields or two indication fields in SIB1 or RRC signaling, carrying information B and information C respectively.

The above is described by taking the unified configuration of the first information as an example where the time window for not transmitting the first downlink channel and the time window for not transmitting the first uplink channel are used as an example. Optionally, the time window for not transmitting the downlink channel and the time window for not transmitting the uplink channel may also be configured independently, which is not specifically limited here.

The communication behavior between the network device and the terminal device under the configuration of the first information is introduced above. It should be noted that the first information is different from the DRX configuration of the terminal device. If the network device sends the first information to the terminal device, and the DRX configuration of the terminal device is also configured, and the DRX mechanism of the terminal device and the DTX mechanism of the network device coexist, the terminal device and the network device can communicate in the following manner.

In an implementation manner, the network device may send the above-mentioned first information and third information to the terminal device, and the third information is used to instruct the terminal device not to receive the downlink channel within the third time window, that is, the first time window is for the network device The time window in which the terminal device does not transmit the first channel under the DTX mechanism, and the third time window is the time window in which the terminal device does not receive the downlink channel under the DRX mechanism. The terminal device may determine a fourth time window according to the first time window and/or the third time window, and not transmit the first channel within the fourth time window.

It should be noted that the first information and the third information may be sent simultaneously or separately, and the present application does not limit the sending order of the first information and the third information.

Exemplarily, the fourth time window is the union of the first time window and the third time window. Alternatively, the fourth time window is the intersection of the first time window and the third time window. Alternatively, the fourth time window is the first time window, that is, the priority of the first information is higher than that of the second information, and the terminal device and the network device communicate according to the first information. Alternatively, the fourth time window is the third time window, that is, the priority of the first information is lower than that of the second information, and the terminal device and the network device communicate according to the third information.

According to the previous terminology introduction, it can be seen that the DRX mechanism of the terminal device has two cycle configurations: Long DRX cycle and Short DRX cycle. After introducing the first cycle indicated by the first information, how to switch between these three cycles is a problem that needs to be solved. .

To solve this problem, in one implementation, when the Short DRX cycle starts/begins to execute, a timer is started, and the duration of the timer can be configured. During the running of this timer, execute according to the rules of short DRX cycle. At the end of the timer, if there are no other new indications/changes/data transmissions, after the timer expires, the first cycle is executed.

In another implementation, when the Long DRX cycle starts/begins to execute, a timer is started, and the duration of the timer can be configured. During the running of this timer, it is executed according to the rules of long DRX cycle. At the end of the timer, if there are no other new indications/changes/data transmissions, after the timer expires, the first cycle is executed.

In yet another implementation manner, when the first cycle is started/executed, a timer is started, and the duration of the timer can be configured. During the running of this timer, execute according to the rules of gNB DTX. At the end of the timer, if there is no other new indication/change/data transmission, execute the Short DRX cycle or the Long DRX cycle after the timer ends.

The above three implementation methods only introduce the conversion rules between the first cycle and the cycle of the DRX mechanism of the terminal device. For the conversion rules between the Short DRX cycle and the Long DRX cycle in the DRX mechanism of the terminal device, please refer to the previous terminology introduction, here I won't repeat it.
