Description

Communication method and device

Technical Field

The present application relates to the field of communications, and more particularly, to a transmission communication method and apparatus.

Background

In existing communication systems, reducing power consumption of terminal devices has always been a concern. In the existing technology, a semi-static Discontinuous Reception (DRX) mechanism and a dynamic power saving message (e.g., Go-To-Sleep (GTS) message) mechanism are combined To control the terminal device To be in a Sleep state, which is helpful for further reducing the power consumption of the terminal device. The following description will take the power saving message as GTS as an example.

The DRX mechanism is that a network device configures DRX parameters including a DRX cycle (DRX cycle), an ON Duration Timer (ON Duration Timer) length, an inactive time Timer (inactive Timer) length, a Retransmission Timer (Retransmission Timer) length, and the like for a terminal device, and controls the terminal device to be in an OFF mode or an active mode through a corresponding Timer. For example, when the duration timer of DRX, or the inactivity time timer, or the retransmission timer is counting, the terminal device is in an active state. That is, in the DRX active period (active time), the terminal device is in an active state and needs to perform blind detection on the PDCCH. In other times except the DRX active period, the terminal equipment is in a dormant state, and blind detection on a PDCCH search space is not needed. Since the DRX parameters are configured by the network device in a semi-static manner for the terminal device, the configuration of the DRX parameters is generally not changed for a long time. Therefore, even if the terminal device has no data to receive in the DRX active period, the terminal device still needs to be in an active state, which results in a relatively limited power consumption of the terminal device reduced based on the DRX mechanism. In order to further reduce the power consumption of the terminal device, the GTS is combined on the basis of the DRX mechanism to dynamically adjust the terminal device to be in a dormant state or an active state. That is, when the network device does not transmit data to the terminal device, the terminal device may be notified to enter the sleep state in the DRX active period by transmitting a GTS message to the terminal device.

However, in the mechanism for dynamically adjusting the terminal device to enter the sleep state through the GTS message, the GTS message can only indicate that the terminal device is in the sleep state for a fixed duration, so that the power saving of the terminal device is very limited under the condition of single GTS message indication. Specifically, when the terminal device does not need to receive data in the remaining time period of the DRX active period, and the duration indicated by the GTS is less than the remaining duration of the DRX duration, the terminal device is still active for a period of time in the DRX active period, and power consumption during the period of time in the active state is unnecessary. For example, the remaining duration of the DRX duration is 5ms, and the duration that the GTS indicates that the terminal device is in the sleep state is 2ms, then in the DRX active period, the terminal device may still be in the active state for 3 ms.

Disclosure of Invention

The application provides a communication method and device, which are beneficial to improving the electric quantity saved by terminal equipment.

In a first aspect, a communication method is provided, including: the method comprises the steps that terminal equipment receives a first message sent by network equipment, wherein the first message is used for indicating the terminal equipment to enter a dormant state in a Discontinuous Reception (DRX) active period; if a first preset condition is met when the first message is received, the terminal equipment is in the dormant state in the rest time period of the DRX cycle in which the DRX active period is located; and/or if the first preset condition is not met when the first message is received, the terminal equipment is in the dormant state within a first time period after the first message is received.

In the embodiment of the application, the terminal device is determined to be in the dormant state in the first time period or the remaining time period according to whether the first preset condition is met or not when the first message is received, so that the electric quantity saved by the terminal device is favorably improved. In the prior art, when the network device indicates the terminal device to be in the dormant state through the GTS and the duration indicated by the GTS is less than the remaining duration of the DRX duration, the terminal device is still in the active state for a period of time in the DRX active period, which causes unnecessary power consumption. Wherein the DRX duration is the timing duration of a DRX duration timer.

Further, under two conditions, namely, under the condition that the first preset condition is met when the first message is received and under the condition that the first preset condition is not met when the first message is received, the terminal device is in a dormant state in the first time period or in a dormant state in the remaining time period according to the first message, which is beneficial to improving the flexibility of the network device indicating that the terminal device is in the dormant state through the first message and is beneficial to balancing between saving electric quantity and avoiding prolonging of communication delay of the terminal device and the network device.

In one possible implementation, the first time period is shorter than the remaining time period.

In the embodiment of the application, if the first preset condition is met, the terminal device is controlled to be in the dormant state in the remaining time period through the first message, and if the first preset condition is not met, the terminal device is controlled to be in the dormant state in the first time period through the first message, so that the communication delay between the terminal device and the network device is not increased generally under the condition of reducing the electric quantity consumed by the terminal device.

In one possible implementation, the first preset condition includes any one of the following conditions: only a DRX duration timer is timed in the decision condition of the DRX active period; and the first message is received in a second time period before the DRX duration, and the terminal equipment is in a dormant state in the second time period.

In this embodiment of the present application, if the first preset condition is that only the DRX duration timer is satisfied for timing in the determination condition of the DRX active period, and when the first preset condition is satisfied, it is determined that the terminal device does not have data that needs to be transmitted and data that needs to be received in the DRX active period, then the terminal device may be controlled to be in the dormant state in the remaining time period through the first message, which is beneficial to reducing the power consumption of the terminal device. When the first preset condition is not met, the terminal equipment is controlled to be in a dormant state in the first time period, and the electric quantity consumed by the terminal equipment is favorably reduced.

In this embodiment of the application, if the first preset condition is that the first message is received in a second time period before the DRX duration, and the terminal device is in a dormant state in the second time period, and when the first preset condition is met, it is determined that the current terminal device may not have a need for data transmission with the network device, or data transmission with the network device has been completed before the second time period, the terminal device may be controlled to be in the dormant state in the remaining time period by the first message, which is beneficial to reducing power consumption of the terminal device, and accordingly, since the current terminal device may not have a need for data transmission with the network device, or data transmission with the network device has been completed before the second time period, the terminal device is controlled to be in the dormant state in the remaining time period, the time delay of the communication between the network device and the terminal device is not increased generally. When the first preset condition is not met, the terminal equipment is controlled to be in a dormant state in the first time period, and the electric quantity consumed by the terminal equipment is favorably reduced.

In a possible implementation manner, the first preset condition is that only a DRX duration timer is satisfied in the decision condition of the DRX active period, and the receiving, by the terminal device, a first message sent by a network device includes: and the terminal equipment receives the first message on a first time domain resource, the first time domain resource and a second time domain resource occupied by Physical Downlink Control Channel (PDCCH) detection are positioned in the same time slot, and the PDCCH is not detected on the second time domain resource by the terminal equipment.

In the embodiment of the present application, if the first time domain resource and the second time domain resource are located in the same time slot, after receiving the first message on the first time domain resource, the terminal device does not perform PDCCH detection on the second time domain resource, which is beneficial to reducing the electric quantity consumed by the terminal device.

In one possible implementation, the first time domain resource and the second time domain resource at least partially overlap.

In a possible implementation manner, the first time domain resource and the second time domain resource satisfy at least one of the following second preset conditions: the first time domain resource is a subset of the second time domain resource, a time difference between a start symbol of the first time domain resource and a start symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an end symbol of the first time domain resource and an end symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an end symbol of the first time domain resource and a start symbol of the second time domain resource is less than or equal to a time threshold, and a time difference between a start symbol of the first time domain resource and an end symbol of the second time domain resource is less than or equal to a time threshold.

In the embodiment of the application, the incidence relation between the first time domain resource and the second time domain resource is determined through the time threshold, which is beneficial to simplifying the determination mode for determining the first time domain resource and the second time domain resource.

In the embodiment of the application, the terminal device is determined to be in the dormant state in the first time period or the remaining time period according to whether the first preset condition is met or not when the first message is received, so that the electric quantity saved by the terminal device is favorably improved. In the prior art, when the network device indicates the terminal device to be in the dormant state through the GTS and the duration indicated by the GTS is less than the remaining duration of the DRX duration, the terminal device is still in the active state for a period of time in the DRX active period, which causes unnecessary power consumption.

Further, under two conditions, namely, under the condition that the first preset condition is met when the first message is received and under the condition that the preset condition is not met when the first message is received, the terminal device is in a dormant state in the first time period or in a dormant state in the remaining time period according to the first message, which is beneficial to improving the flexibility of the network device indicating that the terminal device is in the dormant state through the first message and is beneficial to balancing between saving electric quantity and avoiding prolonging of communication delay of the terminal device and the network device.

In the embodiment of the application, if the first preset condition is met, the terminal device is controlled to be in the dormant state in the remaining time period through the first message, and if the first preset condition is not met, the terminal device is controlled to be in the dormant state in the first time period through the first message, so that the communication delay between the terminal device and the network device is not increased under the condition that the electric quantity consumed by the terminal device is reduced.

In one possible implementation, the first preset condition includes at least one of the following conditions: only a DRX duration timer is timed in the decision condition of the DRX active period; and the first message is received in a second time period before the DRX duration, and the terminal equipment is in a dormant state in the second time period.

For ease of understanding, terms referred to in the present application will be described first.

One, DRX active time and active state

The terminal device is in an active state during the DRX active period. The DRX active period may specifically include the following cases:

in case one, any one of a drx Duration Timer (drx-on Duration Timer), a drx Inactivity Timer (drx-Inactivity Timer), a drx downlink Retransmission Timer (drx-Retransmission Timer D L), a drx uplink Retransmission Timer (drx-Retransmission Timer U L), and a random access Contention Resolution Timer (ra-Contention Resolution Timer) is in a time state.

In the first case, if only the DRX duration timer is counted and the other timers are not counted in the above timers, it is a meaning of "only the DRX duration timer is counted in the determination condition of the DRX active period" in the embodiment of the present application.

In case two, a Scheduling Request (SR) is transmitted through a Physical Uplink Control Channel (PUCCH), and the scheduling request is pending.

Case three, after successfully receiving a random access response corresponding to a non-contention based random access preamble (preamble), a Physical Downlink Control Channel (PDCCH) indicating a new transmission and satisfying the following conditions has not been received: the PDCCH corresponds to a cell radio network temporary identifier (C-RNTI) of a Medium Access Control (MAC) entity.

It should be noted that, for the above three cases, if only the DRX duration timer is used to time the timer, but the other timers in the case one are not used to time, and the terminal device is not in the state described in the case two and the case three, that is, the other meaning of "only satisfying the DRX duration timer for time in the determination condition of the DRX active period" in the embodiment of the present application is obtained.

Accordingly, in any one or more of the three cases, the terminal device needs to detect the PDCCH, where detecting the PDCCH includes detecting a PDCCH corresponding to a Radio Network Temporary Identifier (RNTI): cell-RNTI (C-RNTI), configuration scheduling-RNTI (CS-RNTI), interrupt-RNTI (INT-RNTI), slot format identifier RNTI (slot format indicator-RNTI, SFI-RNTI), semi-persistent channel state information RNTI (SP-CSI-RNTI), PUCCH-transmission power control RNTI (TPC-PUCCH-RNTI), PUSCH transmission power control RNTI (transmit power-PUSCH-RNTI), and sounding reference signal transmission power control RNTI (SRS-power-signaling-signal RNTI).

In the above, the PDCCH corresponding to the RNTI may refer to a Cyclic Redundancy Check (CRC) bit that scrambles DCI carried by the PDCCH with the RNTI.

It should be noted that, the DRX active period may include other situations specified in future communication protocols besides the above situations, and this is not specifically limited in the embodiment of the present application.

Second, DRX sleep state

The terminal device may be in a sleep state (also referred to as a power saving state) during a time other than the DRX active period (e.g., DRX inactive time). For example, the terminal device may not detect the PDCCH during the DRX sleep period. In one DRX cycle, periods other than the above DRX active period may be regarded as DRX sleep periods.

Correspondingly, when the terminal equipment is in a dormant state, the method comprises the following steps of not performing PDCCH detection corresponding to RNTI: cell-RNTI (C-RNTI), configured scheduling-RNTI (CS-RNTI), interrupt-RNTI (INT-RNTI), slot format identifier RNTI (slot format indicator-RNTI, SFI-RNTI), semi-persistent channel state information RNTI (SP-CSI-RNTI), PUCCH-transmission power control RNTI (TPC-PUCCH-RNTI), PUSCH transmission power control RNTI (transmit power-PUSCH, TPC-PUSCH-RNTI), sounding reference signal transmission power control RNTI (SRS-power-TPC-signaling-RNTI), and the like.

Based on the above description, the DRX-based mechanism is first described in conjunction with fig. 2, and then a power saving message is described based on DRX: and the terminal equipment enters a sleep (GTS) message to control the terminal equipment to enter a sleep state. It should be noted that, in fig. 2, only the DRX cycle 210 and the DRX cycle 220 are taken as examples, and DRX also includes other configurations specified in the current communication protocol, and the method of the embodiment of the present application may also be used.

In the existing communication protocols (e.g. L TE and NR 15 versions), DRX mechanisms are introduced, which save power of the terminal device to some extent, and the principle of the DRX mechanism is shown in fig. 2.

In the DRX mechanism, the DRX cycles are divided into different DRX cycles (DRX cycles), a DRX duration (ON duration) is configured in the DRX cycle 210, and during the ON duration, an ON duration timer counts time, and the terminal device needs to perform PDCCH detection (PDCCH monitoring), and if none of the PDCCH detections in the ON duration detect uplink (U L) data scheduling or downlink (D L) data scheduling, the terminal device enters a DRX sleep state (OFF mode) for a time other than the ON duration in the DRX cycle, so as to save power.

In the DRX cycle 220, if the terminal device detects a newly transmitted D L data schedule or U L data schedule during the PDCCH detection within the DRX duration, it starts or restarts a DRX-Inactivity Timer, and during the DRX-Inactivity Timer, the terminal device also needs PDCCH detection as in the ON duration, specifically, the L TE and NR 15 protocols specify that the terminal device needs PDCCH detection during the ON duration, DRX-Inactivity Timer, or other conditions (such as retransmission Timer timing, etc.), and the above time period is collectively referred to as the DRX active period.

When the ON duration Timer and the DRX-Inactivity Timer stop timing, and other timers (such as DRX-Retransmission Timer) also stop timing, the DRX active period is ended, the terminal device enters a DRX dormant state, and PDCCH detection is not performed, so as to save electric quantity.

In the above DRX mechanism, DRX parameters such as DRX cycle, ON duration timer, DRX-Inactivity timer, etc. are configured by the network device in a semi-static manner for the terminal device through RRC messages, where, when a typical configuration example is { DRX cycle, ON duration timer, Inactivity timer }, the corresponding configuration parameters may be {160ms,8ms,100ms }, {320ms,10ms,80ms }, etc. That is, the terminal device can enter the sleep state only according to the configured DRX parameters until the next time the DRX parameters are configured. However, the network device is most likely not to transmit data to the terminal device for a long period of time, and at this time, if the terminal device still enters the DRX duration in the DRX cycle according to the DRX parameters, and performs PDCCH detection, the power of the terminal device is still wasted.

In order to avoid the above situation, the network device may dynamically instruct the terminal device to enter the sleep state through the GTS message based on the DRX mechanism. Specifically, the manner of dynamically indicating the terminal device to enter the sleep state through the GTS message is generally that the GTS indicates that the terminal device is in the sleep state for the first time period.

That is to say, each GTS message corresponds to a fixed time length, that is, a first time length, and the terminal device is in the dormant state within the first time length by using the receiving time of receiving the GTS message as the starting time, where the time length is the first time length by using the receiving time as the starting time.

It should be noted that each GTS message may carry an index indicating a time duration, where the index may be selected from multiple indexes, and different indexes in the multiple indexes have different time lengths corresponding to different time durations.

The above method indicates that the terminal device is in the dormant state at the first time period, when the first time period is less than the remaining time period of the DRX duration, the network device has no way to control the terminal device to be in the dormant state at the whole remaining time period through the GTS message, and after the first time period, the terminal device still needs to enter the DRX active period to perform PDCCH detection.

In order to avoid the foregoing situation, embodiments of the present application provide a communication method, where the meanings of the first message are different under different conditions, which is beneficial to flexibly controlling the duration of the terminal device in the sleep state.

The communication method according to the embodiment of the present application is described in detail below with reference to fig. 3. The method shown in fig. 3 includes steps 310 through 340.

And 310, the network equipment generates a first message, wherein the first message is used for indicating the terminal equipment to enter a dormant state in the Discontinuous Reception (DRX) active period.

The first message may be the above power saving message, a GTS message, a wake up message (WUS), or a message specified in a future communication protocol and having the same function, which is not specifically limited in this embodiment of the present application.

The network device sends 320 a first message to the terminal device.

330, if a first preset condition is met when the first message is received, the terminal device is in the dormant state in the remaining time period of the DRX cycle in which the DRX active period is located.

The first preset condition is used for the terminal device to determine whether the period in which the first message indicates that the terminal device is in the sleep state is the remaining period in the foregoing or the target period in the following. Optionally, the first preset condition is used to indicate a time when the terminal device receives the first message, and the first preset condition may also be used to indicate a state when the terminal device receives the first message.

If the first message is received and a first preset condition is met, the first message is used for indicating that the terminal equipment is in a dormant state in the residual time period of the DRX cycle of the DRX active period, and correspondingly, the terminal equipment can be in the dormant state in the residual time period of the DRX cycle of the DRX active period after receiving the first message.

The remaining period of the DRX cycle may include a period of time with a reception time of the terminal device receiving the first message as a start time and an end time of the DRX cycle as an end time. It should be noted that the remaining time period may include a time period corresponding to a DRX cycle in which the entire DRX active period is located, or may include a time period corresponding to a DRX cycle in which a part of the DRX active period is located. Referring to fig. 4, the first DRX cycle 410 is a cycle before the second DRX cycle 420, and the DRX cycle in which the DRX active period is located is the second DRX cycle 420, and assuming that the terminal device receives the first message in the first DRX cycle 410, the remaining time of the DRX cycle may include the entire second DRX cycle 420, based on the definition of the remaining time of the DRX cycle. Assuming that the terminal device receives the first message at the receiving time 430 of the second DRX cycle 420, based on the definition of the remaining time of the DRX cycle, the remaining time of the DRX cycle is a period of time 440 with the receiving time 430 as a starting time and with the ending time of the second DRX cycle 420 as an ending time, that is, a DRX cycle in which a partial DRX active period is located.

It should be noted that the first preset condition may be specified in a communication protocol, or may be pre-configured by the network device to the terminal device, and this is not specifically limited in this embodiment of the application.

340, if the first preset condition is not met when the first message is received, the terminal device is in the dormant state within a first time period after the first message is received.

If the first preset condition is not met when the first message is received, where the first message is used to indicate that the terminal device is in the dormant state within a first time period after the first message is received, the terminal device may be in the dormant state within the first time period after the first message is received.

The first preset condition may include one preset condition or a plurality of preset conditions, for example, in the following implementation form four of the first preset condition, it is understood that the first preset condition includes two conditions, that is, the first message is received in a second time period before the DRX duration, and the terminal device is in a dormant state in the second time period. For another example, in the second implementation form of the first preset condition, it is understood that the first preset condition includes a condition that only the DRX duration timer is satisfied in the decision condition of the DRX active period.

Several possible implementations of the first preset condition are described below with reference to the drawings.

In implementation form one, a DRX duration timer (ON duration timer) is counting.

If the first preset condition in the first implementation form is met when the first message is received, the terminal device is in the DRX active period, that is, the terminal device may be in any one of the above-mentioned cases one to three. In this case, the terminal device may have a possibility that data is to be transmitted or received, but if the power saving requirement is higher than the requirement for shortening the communication delay, the terminal device may be controlled to be in the dormant state in the remaining time period through the first message.

In the second implementation form, the DRX duration timer is only satisfied in the decision condition of the DRX active period.

The above-mentioned DRX active period determination condition may be understood as a condition for triggering the DRX active period, and a specific meaning thereof may include any one of two meanings that "the DRX duration timer timing is only satisfied among the DRX active period determination conditions described in the above three cases," and for brevity, the description is omitted here.

If the first preset condition in the implementation form two is met when the first message is received, the terminal equipment in the DRX active period is only timed by the DRX duration timer, and no data needs to be sent or received in the DRX active period. In this case, in order to reduce the power of the terminal device, the terminal device may be controlled to be in the sleep state for the remaining period of time by the first message.

It should be noted that, in implementation form two, only the DRX duration timer is satisfied in the decision conditions of the DRX active period, that is, the terminal device is in the above-mentioned case one, only the DRX duration timer is timed, and other conditions except the DRX duration timer are not satisfied, and the case two and the case three are not satisfied.

It should be noted that, in the first implementation manner and the second implementation manner, the timer in the terminal device in the timing state may be adjusted to be in the non-timing state, so that the terminal device enters the sleep state. For example, when only the DRX duration timer is running, the DRX duration timer may be adjusted to a non-running state so that the terminal device enters a sleep state.

Through the first implementation manner and the second implementation manner, it can be limited that the terminal device is controlled to be in the dormant state in the remaining time period or the first time period when the first message is received within the DRX duration. In the following, with reference to the third implementation and the fourth implementation, it is limited that the terminal device is controlled to be in the sleep state during the remaining time period or the first time period when the first message is received before the DRX duration.

In a third implementation form, the first message is received within a second time period before the DRX duration.

The second period of time is located before the DRX duration, and may include that the second period of time is located in a DRX cycle in which the DRX duration is located, or the DRX cycle in which the second period of time is located is different from the DRX cycle in which the DRX duration is located.

When the second period of time and the DRX duration are in the same DRX cycle, the second period of time may be within a starting offset period of the DRX duration, see fig. 5, in the DRX cycle 520, the DRX duration may not be at the beginning of the DRX cycle, that is, an offset period existing between the starting time of the DRX duration and the starting time of the DRX cycle is the starting offset period 530.

When the DRX cycle of the second period of time is different from the DRX cycle of the DRX duration, that is, the second period of time is located in the previous DRX cycle before the DRX cycle of the DRX duration, referring to fig. 6, the second period of time is located in the DRX cycle 610, the DRX cycle of the DRX active period is the DRX cycle 620, and the DRX cycle 610 is the DRX cycle before the DRX cycle 620.

In an implementation form of the fourth aspect, the first message is received within a second time period before the DRX duration, and the terminal device is in a dormant state within the second time period.

It should be noted that, in implementation form four, the relative position of the second period to the DRX duration may be referred to the related description in implementation form three, and for brevity, no further description is provided here.

If the first preset condition in the fourth implementation form is met when the first message is received, the terminal device is in the dormant state in the second time period, which indicates that the current terminal device may not have a requirement for data transmission with the network device, or data transmission with the network device has been completed before the second time period, and if the preset condition is met, the terminal device may be controlled to be in the dormant state in the remaining time period by the first message in order to reduce the electric quantity of the terminal device.

Accordingly, if the terminal device is in the active state for the second period of time, it is indicated that the data required to be transmitted in the last DRX cycle (410) is not completely transmitted, and therefore, in this case, in order to avoid prolonging the delay of the terminal device communicating with the network device, the terminal device may be controlled to be in the dormant state for the first period of time by the first message.

It should be noted that the second time period in the third preset condition or the fourth preset condition may be specified by a protocol, or may be configured by the network device for the terminal device in advance, for example, the network device may indicate the terminal device in a semi-static manner through RRC signaling, which is not limited in this embodiment of the present application.

Optionally, the configuration parameter for configuring the second time includes at least one of the following parameters: a time position of the second period in the DRX cycle, a time position of the second period relative to the DRX duration, a time length of the second period, a resource configuration of a Tracking Reference Signal (TRS) within the second period, a resource configuration of a channel state information-reference signal (CSI-RS), and a resource configuration of a first message (e.g., WUS) within the second period. Wherein the CSI-RS may be a CSI-RS for beam training.

Optionally, the time position of the second period in the DRX cycle of the DRX active period may be represented by an offset period of the second period relative to the starting time of the DRX cycle (e.g., DRX cycle 520, DRX cycle 620) of the DRX duration. Accordingly, the second period may also be represented by an offset period of the second period with respect to the ending time of the last period (e.g., DRX cycle 510, DRX cycle 610) of the DRX cycle in which the DRX duration is located. The embodiment of the present application is not particularly limited to this.

The 4 preset conditions may be used individually, or may be used in combination as the first preset condition. For example, the fourth preset condition may be combined with the second preset condition as the first preset condition, when the first message is received in the second time period before the DRX duration, and the terminal device is in the dormant state in the second time period, and only the DRX duration timer is satisfied in the decision condition of the DRX active period for timing, it may be ensured that the terminal device completes data transmission with the network device in the previous DRX cycle, and the DRX cycle in which the DRX active period is located does not need to perform data transmission with the network device, at this time, the terminal device may be controlled to be in the dormant state in the DRX cycle in which the DRX active period is located through the first message, that is, the terminal device may be in the dormant state in the entire DRX cycle, so as to save the power of the terminal device to the maximum extent.

The first message of the embodiment of the present application may multiplex various indication information used in the current communication protocol to help the terminal device save power, such as the GTS message or the WUS message introduced above. In the multiplexing mode, it may be indicated, through the target indication information carried in the GTS message, whether the GTS message controls the terminal device to be in the dormant state in a manner specified in a conventional communication protocol (for example, in the foregoing manner one or manner two), or controls the terminal device to be in the dormant state based on a manner of this embodiment (i.e., the manner described in fig. 3). That is to say, the target indication information carried in the GTS is used to indicate the GTS message to control the terminal device to be in the dormant state based on the method of the embodiment of the present application.

Optionally, the target indication information may be an index corresponding to the first time length carried in the GTS message.

In the above description mode two, it is mentioned that when the GTS message is used to control the terminal device to be in the dormant state at the first time period, the corresponding first time duration of the first time period may be selected from a plurality of configured time durations, and different ones of the plurality of time durations correspond to different indexes, and when the GTS message carries the index corresponding to the first time duration, the GTS message is indicated to control the terminal device to be in the dormant state according to the method in the embodiment of the present application.

Except that the GTS message is indicated by the target indication information to control the terminal device to be in the dormant state based on the method of the embodiment of the present application, the terminal device may also autonomously determine whether the GTS message controls the terminal device to be in the dormant state based on the method of the embodiment of the present application. For example, when the network device configures only GTS parameters for the terminal device through RRC signaling and does not configure WUS parameters, the terminal device may autonomously determine that the GTS message controls the terminal device to be in a sleep state based on the method of the embodiment of the present application. Of course, the terminal device may also directly default to any situation, and the GTS message or the WUS controls the terminal device to be in the sleep state based on the method of the embodiment of the present application. The embodiments of the present application do not limit this.

In the above method, the terminal device may receive the first message within the DRX duration, that is, the first time domain resource for transmitting the first message may be located in the same time slot as the second time domain resource detected by the PDCCH. In order to reduce the power consumption of the terminal device, another embodiment of the present application provides a method of transmitting a first message. A method of transmitting a first message according to an embodiment of the present application is described below with reference to fig. 7. The method shown in fig. 7 includes steps 710 to 720.

710, a terminal device detects a first message sent by a network device on a first time domain resource, where the first time domain resource and a second time domain resource occupied by PDCCH detection are located in the same time slot.

Optionally, the first time domain resource and the second time domain resource at least partially overlap in the time slot, that is, the first time domain resource and the second time domain resource completely overlap, or the second time domain resource and the first time domain resource partially overlap. For example, the first time domain and the second time domain resource have a partial symbol identity.

When the second time domain resource is partially overlapped with the first time domain resource, the second time domain resource may include the first time domain resource, or the first time domain resource is a subset of the second time domain resource.

Alternatively, it may be determined by a time threshold that the first time domain resource is located in the same time slot as the second time domain resource. For example, the first time domain resource and the second time domain resource satisfy any one of the following second preset conditions: a time difference between a starting symbol of the first time domain resource and a starting symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an ending symbol of the first time domain resource and an ending symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an ending symbol of the first time domain resource and a starting symbol of the second time domain resource is less than or equal to a time threshold, and a time difference between a starting symbol of the first time domain resource and an ending symbol of the second time domain resource is less than or equal to a time threshold.

The time threshold under different conditions in the second preset condition may be different, and may also be the same as the time threshold in this embodiment of the present application.

The time threshold may be in units of the number of symbols, for example, 2 symbols may be referred to when the time threshold is 2. The time threshold may also be expressed in absolute time, for example, 2 milliseconds when the time threshold is 2. The embodiment of the present application is not limited to drama.

It should be noted that the time threshold may be specified by a protocol, or may be configured by the network device for the terminal device in advance, for example, the network device may indicate the terminal device in a semi-static manner through RRC signaling, which is not limited in this embodiment of the present application.

The first time domain resource and the second time domain resource may be configured in the following manner and located in the same time slot. The second time domain resource detected by the PDCCH may be configured for the terminal device in a manner specified in the communication protocol. For example, the network device configures a PDCCH configuration parameter for the terminal device by sending a system message or an RRC message, where the PDCCH configuration parameter includes a control resource set (CORESET), a search space (search space), and the like, and the second time domain resource is jointly determined by the CORESET and the search space.

Optionally, if the configuration parameters include the coreset ID, the symbol length of the PDCCH resource, the search space ID, the coreset ID associated with the search space, the time slot where the PDCCH resource is located, the initial symbol in the time slot, the type of the search space, and the DCI format associated with the search space. The time domain resource for PDCCH detection can be determined according to all CORESET in the configuration parameters, the time slot in which all search space PDCCH resources are located, the initial symbol in the time slot, and the symbol length.

Accordingly, the first time domain resource for detecting the first message may be determined by one or more search spaces in the configuration parameters, that is, the first message is carried by one or more DCI formats, and each DCI format carrying the first message may be associated to the one or more search spaces and then associated to CORESET through the search spaces, so as to obtain the time domain resource for detecting the first message. In this case, the first time domain resource is a subset of the second time domain resource.

It should be noted that, the first message may be carried by a PDCCH, may also be separately transmitted, or may be carried by other signaling, which is not limited in this embodiment of the present application. If the first message is not carried by the PDCCH, the time domain resource for transmitting the first message (i.e., the first time domain) and the time domain resource occupied by the PDCCH detection (i.e., the second time domain resource) may also satisfy the above-mentioned position relationship, i.e., the first time domain resource and the second time domain resource are located in the same time slot. Specifically, the position relationship between the first time domain resource and the second time domain resource can be determined by the time threshold. For example, the first time domain resource and the second time domain resource satisfy any one of the following second preset conditions: a time difference between a starting symbol of the first time domain resource and a starting symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an ending symbol of the first time domain resource and an ending symbol of the second time domain resource is less than or equal to a time threshold, a time difference between an ending symbol of the first time domain resource and a starting symbol of the second time domain resource is less than or equal to a time threshold, and a time difference between a starting symbol of the first time domain resource and an ending symbol of the second time domain resource is less than or equal to a time threshold. Accordingly, after the terminal device detects the first message on the first time domain resource, the terminal device may not perform PDCCH detection on the second time domain resource. For the above, specific descriptions of the time threshold and the like may be referred to, and for brevity, are not described herein again.

720, if the first message is detected on the first time domain resource, the terminal device does not detect the PDCCH on the second time domain resource.

In this embodiment of the present application, when the first time domain resource and the second time domain resource are located in the same time slot, after the terminal device detects the first message on the first time domain resource, the terminal device may not detect the PDCCH on the second resource on the time slot any more, and directly enter the sleep state, so as to save the power.

The method shown in fig. 3 may be used in combination with the method shown in fig. 7, and the method shown in fig. 3 may also be used separately from the method shown in fig. 7, which is not limited in this embodiment. In the respective use procedure, the terminal device according to fig. 3 can enter the sleep state at any time slot after receiving the first message. Accordingly, when the method shown in fig. 7 is used alone, the DRX mechanism may be used in combination with or completely separated from the DRX mechanism specified in the current protocol, which is not limited in the embodiment of the present application. When the method shown in fig. 3 may be used in combination with the method shown in fig. 7, after receiving the first message according to the method shown in fig. 3, if the first time domain resource and the second time domain resource are in the same time slot, the terminal device may enter a sleep state in the time slot and be in the sleep state in the first time period or the remaining time period.
