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 been a concern. In the existing technology, the terminal device can be controlled To be in a dormant state by combining a semi-static discontinuous reception (Discontinuous Reception, DRX) mechanism with a dynamic power saving message (e.g., a Go-To-Sleep (GTS) message) mechanism, 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, i.e. the network device configures the terminal device with DRX parameters including a DRX cycle (DRX cycle), a duration Timer (ON Duration Timer) length, an Inactivity Timer (Inactivity Timer) length, a retransmission Timer (Retransmission Timer) length, etc., and controls the terminal device to be in a sleep state (OFF mode) or an active state (active mode) through the corresponding Timer. For example, when the DRX duration timer, or the inactivity time timer, or the retransmission timer is counting, the terminal device is in an active state. That is, the terminal device is in an active state during a DRX active period (active time), and blind detection of the PDCCH is required. In other times except for the DRX active period, the terminal device is in a sleep state, and blind detection on the PDCCH search space is not required. Since the DRX parameters are configured by the network device in a semi-static manner for the terminal device, these parameter configurations will not change during a longer period of time. Thus, even if the terminal device does not have data to receive during the DRX active period, the terminal device still needs to be in an active state, resulting in a limited power consumption of the terminal device based on the reduction of the DRX mechanism. In order to further reduce the power consumption of the terminal device, the terminal device is dynamically adjusted to be in a dormant state or an active state by combining with the GTS on the basis of the DRX mechanism. That is, when the network device does not transmit data to the terminal device, the terminal device may be informed to enter the sleep state during the DRX active period by transmitting a GTS message to the terminal device.

However, in this mechanism for dynamically adjusting the terminal device to enter the sleep state through the GTS message, the GTS message only indicates that the terminal device is in the sleep state for a fixed period of time, so that the amount of electricity that the terminal device can save is very limited in the case of a single GTS message indication. Specifically, when the terminal device does not need to receive data in the remaining period of the DRX active period and the duration indicated by the GTS is smaller than the remaining period of the DRX duration, the terminal device remains in an active state for a period of time in the DRX active period, and the power consumption of the active state for the period of time is unnecessary. For example, if the remaining duration of the DRX duration is 5ms and the duration of the gts indicates that the terminal device is in the sleep state is 2ms, the terminal device may still be in the active state for 3ms during the DRX active period.

Disclosure of Invention

The communication method and the communication device are beneficial to improving the electric quantity saved by the terminal equipment.

In a first aspect, a communication method is provided, including: the method comprises the steps that a terminal device receives a first message sent by a network device, wherein the first message is used for indicating the terminal device to enter a dormant state in a Discontinuous Reception (DRX) active period; if the first message is received and the first preset condition is met, the terminal equipment is in the dormant state in the residual time period of the DRX period where 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 in a first time period after the first message is received.

In the embodiment of the application, according to whether the first preset condition is met when the first message is received, the terminal equipment is determined to be in the dormant state in the first time period or the residual time period, so that the electric quantity saved by the terminal equipment is improved. In the prior art, when the network device indicates that the terminal device is in the dormant state through the GTS, and when the GTS indicated duration is smaller than the remaining duration of the DRX duration, the terminal device is still in an active state for a period of time in the DRX active period, so that unnecessary electric quantity consumption is caused. Wherein the DRX duration is the timing duration of a DRX duration timer.

Further, in two cases, namely, in the case that the first preset condition is met when the first message is received and in the case 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 the dormant state in the rest time period according to the first message, so that flexibility of indicating that the terminal device is in the dormant state by the network device through the first message is improved, and balance between saving of electric quantity and avoiding of prolonging of communication delay between the terminal device and the network device is facilitated.

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

In the embodiment of the present application, if the first preset condition is met, the terminal device is controlled to be in a 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, which is favorable for reducing the electric quantity consumed by the terminal device, and generally does not increase the communication delay between the terminal device and the network device.

In one possible implementation, the first preset condition includes any one of the following conditions: only meeting the timing of a DRX duration timer 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 device is in a dormant state in the second time period.

In the embodiment of the present application, if the first preset condition is that only the DRX duration timer is satisfied in the decision 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 to be transmitted and data to be received in the DRX active period, then the terminal device may be controlled to be in a sleep state through the first message in the remaining period, which is favorable for reducing the electric quantity consumed by the terminal device, and accordingly, since the terminal device does not have data to be transmitted and data to be received in the DRX active period, the terminal device is controlled to be in the sleep state in the remaining period, and the time delay of communication between the network device and the terminal device is not increased. When the first preset condition is not met, the terminal equipment is controlled to be in a dormant state in a first time period, and the electric quantity consumed by the terminal equipment is reduced.

In this embodiment of the present application, if the first preset condition is that the first message is received in the second period of time before the DRX duration, and the terminal device is in a dormant state in the second period of time, when the first preset condition is met, it is determined that there is no need for data transmission between the current terminal device and the network device, or data transmission between the current terminal device and the network device has been completed before the second period of time, the terminal device may be controlled to be in a dormant state in the remaining period of time by the first message, so as to be beneficial to reducing the consumed electric quantity of the terminal device, and accordingly, because there is no need for data transmission between the current terminal device and the network device, or data transmission between the current terminal device and the network device has been completed before the second period of time, the terminal device is controlled to be in a dormant state in the remaining period of time, and generally, the delay of communication between the network device and the terminal device will not be increased. When the first preset condition is not met, the terminal equipment is controlled to be in a dormant state in a first time period, and the electric quantity consumed by the terminal equipment is reduced.

In one possible implementation manner, the first preset condition is that only a DRX duration timer is met in the decision condition of the DRX active period, and the terminal device receives a first message sent by a network device, including: 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 terminal equipment does not detect the PDCCH on the second time domain resource.

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 the terminal device receives the first message on the first time domain resource, the terminal device does not detect the PDCCH on the second time domain resource, which is favorable for reducing the electric quantity consumed by the terminal device.

In one possible implementation, the first time domain resource at least partially overlaps with the second time domain resource.

In one possible implementation manner, the first time domain resource and the second time domain resource meet 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 the first time domain resource start symbol and the start symbol of the second time domain resource is less than or equal to a time threshold, a time difference between the first time domain resource end symbol and the end symbol of the second time domain resource is less than or equal to a time threshold, a time difference between the first time domain resource end symbol and the start symbol of the second time domain resource is less than or equal to a time threshold, and a time difference between the first time domain resource start symbol and the end symbol of the second time domain resource is less than or equal to a time threshold.

In the embodiment of the application, the association 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 of determining the first time domain resource and the second time domain resource.

In a second aspect, there is provided a method of transmitting a first message, comprising: the method comprises the steps that a terminal device detects a first message on a first time domain resource, wherein the first time domain resource and a second time domain resource occupied by PDCCH detection are located in the same time slot; 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 a possible implementation manner, the first time domain resource and the second time domain resource meet any one of the following 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, according to whether the first preset condition is met when the first message is received, the terminal equipment is determined to be in the dormant state in the first time period or the residual time period, so that the electric quantity saved by the terminal equipment is improved. In the prior art, when the network device indicates that the terminal device is in the dormant state through the GTS, and when the GTS indicated duration is smaller than the remaining duration of the DRX duration, the terminal device is still in an active state for a period of time in the DRX active period, so that unnecessary electric quantity consumption is caused.

Further, in two cases, namely, in the case that the first preset condition is met when the first message is received and in the case 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 the dormant state in the rest time period according to the first message, so that flexibility of indicating that the terminal device is in the dormant state by the network device through the first message is improved, and balance between saving of electric quantity and avoiding of prolonging of communication delay between the terminal device and the network device is facilitated.

In the embodiment of the application, if the first preset condition is met, the terminal equipment is controlled to be in the dormant state in the residual time period through the first message, and if the first preset condition is not met, the terminal equipment 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 equipment and the network equipment is not increased under the condition of reducing the electric quantity consumed by the terminal equipment.

In one possible implementation, the first preset condition includes at least one of the following conditions: only meeting the timing of a DRX duration timer 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 device is in a dormant state in the second time period.

In the embodiment of the application, the time threshold is used for determining that the first time domain resource and the second time domain resource are located in the same time slot, so that the determination mode for determining the first time domain resource and the second time domain resource is simplified.

For ease of understanding, the terms referred to in this application are introduced first.

1. DRX active period (active time) and active state

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

Any one of the drx duration Timer (drx-on Duration Timer), drx Inactivity Timer (drx-Inactivity Timer), drx downlink retransmission Timer (drx-Retransmission Timer DL), drx uplink retransmission Timer (drx-Retransmission Timer UL) and random access contention resolution Timer (random access Contention Resolution Timer, ra-Contention Resolution Timer) is in the timing state.

It should be noted that, in the first case, if only the DRX duration timer is counted in the above-mentioned timers, but the other timers are not counted, the meaning of "the DRX duration timer is only satisfied in the condition of determining the DRX active period" in the embodiment of the present application is described.

Case two, there is a scheduling request (scheduling request, SR) sent over the physical uplink control channel (Physical Uplink Control Channel, PUCCH), which 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 (physical downlink control channel, PDCCH) indicating a new transmission and satisfying the following conditions has not been received yet: the PDCCH corresponds to a cell radio network temporary identity (cell radio network temporary identifier, C-RNTI) of a medium access control (media access control, MAC) entity.

It should be noted that, for the above three cases, if only the DRX duration timer is counted in the above timers, but the other timers in the first case are not counted, and the terminal device is not in the states described in the second case and the third case, that is, the other meaning of "the DRX duration timer is only satisfied in the determining condition of the DRX active period" in the embodiment of the present application.

Accordingly, in any one or more of the above three cases, the terminal device needs to detect the PDCCH, where detecting the PDCCH includes detecting the PDCCH corresponding to the following radio network temporary identity (radio network temporary identifier, RNTI): cell RNTI (cell-RNTI, C-RNTI), configured scheduling RNTI (configured scheduling-RNTI, CS-RNTI), interrupt RNTI (interrupt-RNTI, INT-RNTI), slot format identity RNTI (slot format indicator-RNTI, SFI-RNTI), semi-permanent channel state information RNTI (semi-persistent channel state information, SP-CSI-RNTI), PUCCH transmit power control RNTI (transmit power control-PUCCH-RNTI, TPC-PUCCH-RNTI), PUSCH transmit power control RNTI (transmit power control-PUSCH-RNTI, TPC-PUSCH-RNTI), and heuristic reference signal transmit power control RNTI (transmit power control-sounding reference signal-RNTI, TPC-SRS-RNTI).

In the above, the PDCCH corresponding to the RNTI may refer to cyclic redundancy check (cyclic redundancy check, CRC) bits of DCI carried by the PDCCH scrambled with the RNTI.

It should be further noted that, in addition to the above cases, the DRX active period may include other cases specified in future communication protocols, which is not specifically limited in the embodiments of the present application.

2. DRX sleep state

The terminal device may be in a dormant state (also called a power saving state) for a time other than the DRX active period, for example, a DRX inactive time (inactive time). For example, the terminal device may not detect the PDCCH during the DRX sleep period. The periods other than the DRX active period described above may be regarded as DRX sleep periods within one DRX cycle.

Correspondingly, when the terminal equipment is in the dormant state, the method comprises the step of detecting the PDCCH without the following RNTI: cell RNTI (cell-RNTI, C-RNTI), configuration scheduling RNTI (configured scheduling-RNTI, CS-RNTI), interrupt RNTI (interrupt-RNTI, INT-RNTI), time slot format identity RNTI (slot format indicator-RNTI, SFI-RNTI), semi-permanent channel state information RNTI (semi-persistent channel state information, SP-CSI-RNTI), PUCCH transmit power control RNTI (transmit power control-PUCCH-RNTI, TPC-PUCCH-RNTI), PUSCH transmit power control RNTI (transmit power control-PUSCH-RNTI, TPC-PUSCH-RNTI), heuristic reference signal transmit power control RNTI (transmit power control-sounding reference signal-RNTI, TPC-SRS-RNTI), and the like.

The following description is based on the above terms, and in connection with fig. 2, a description is first made based on a DRX mechanism, and then a description is made of a power saving message based on DRX: and a control mode for controlling the terminal equipment to enter the sleep state by entering a sleep (GTS) message. It should be noted that, in fig. 2, only the DRX cycle 210 and the DRX cycle 220 are described as an example, the 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 (for example, LTE and NR R15 versions), a DRX mechanism is introduced, which saves the power of the terminal device to a certain extent, and the principle of the DRX mechanism is shown in fig. 2.

In the DRX mechanism, the DRX mechanism is divided into different DRX cycles (DRX cycles), a DRX duration (ON duration) is configured in the DRX cycle 210, in the ON duration, ON duration timer, the terminal device needs to perform PDCCH detection (PDCCH monitoring), and if no Uplink (UL) data scheduling or Downlink (DL) data scheduling is detected in the PDCCH detection in the ON duration, the terminal device enters a DRX sleep state (OFF mode) and does not perform PDCCH detection in the DRX cycle, so as to save power.

In the DRX cycle 220, if the terminal device detects a new DL data schedule or UL data schedule when detecting PDCCH in the DRX duration, a DRX-Inactivity Timer is started or restarted. The terminal device also needs PDCCH detection as in the ON duration during the time of the drx-Inactivity Timer. Specifically, the LTE and NR R15 protocols specify that, under ON duration Timer or DRX-Inactivity Timer, or other conditions (such as retransmission Timer timing, etc.), the terminal device needs to perform PDCCH detection, and these periods are collectively referred to as a DRX active period.

When ON duration Timer and DRX-activity Timer stop timing, and other timers (such as DRX-Retransmission Timer) stop timing, the DRX active period ends, and the terminal device enters a DRX sleep state, and does not perform PDCCH detection, so as to save power.

In the above DRX mechanism, DRX parameters such as DRX cycle, ON duration Timer, DRX-activity Timer, etc. are configured for the terminal device in a semi-static manner by the network device through RRC messages, where typical configuration examples are { DRX cycle, ON duration Timer, activity Timer }, where 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 before the next configuration of the DRX parameters. 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 parameter, the PDCCH is detected, which still wastes the power of the terminal device.

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 on the basis of the DRX mechanism described above. 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 a first duration.

That is, each GTS message corresponds to a fixed time length, that is, a first time length, and the terminal device is in a sleep state in the first time length with a receiving time of receiving the GTS message as a starting time, where the time length is a first time period, that is, a first time period, with 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 correspond to different time durations.

The method indicates that the terminal equipment is in a dormant state in the first time period, when the first time period is smaller than the residual duration of the DRX duration, the network equipment has no method for controlling the terminal equipment to be in the dormant state in the whole residual duration through the GTS message, and after the first time period, the terminal equipment still needs to enter the DRX active period to detect the PDCCH.

In order to avoid the above situation, the embodiment of the application provides a communication method, and under different conditions, the meaning of the first message is different, which is favorable for 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.

The network device generates a first message indicating that the terminal device enters a sleep state during a discontinuous reception DRX active period 310.

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

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

And 330, if the first message is received and the first preset condition is met, the terminal equipment is in the dormant state in the rest period of the DRX cycle where the DRX active period is located.

The above first preset condition is 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 above or the target period in the below. Optionally, the first preset condition is used for indicating a time when the terminal device receives the first message, and the first preset condition may also be used for indicating a state when the terminal device receives the first message.

If the first message satisfies a first preset condition when the first message is received, the first message is used for indicating that the terminal equipment is in a dormant state in the remaining time period of the DRX cycle where the DRX active period is located, and correspondingly, the terminal equipment can be in the dormant state in the remaining time period of the DRX cycle where the DRX active period is located after the first message is received.

The remaining period of time in the DRX cycle may include a period of time with a reception time at which the terminal device receives the first message as a start time and an end time of the DRX cycle as an end time. The remaining period may include a period corresponding to a DRX cycle in which the entire DRX active period is located, or may include a 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 located 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 described above. Assuming that the terminal device receives the first message at the receiving time 430 of the second DRX cycle 420, the remaining time of the DRX cycle is a period 440 with the receiving time 430 as a starting time and the ending time of the second DRX cycle 420 as an ending time, i.e. the DRX cycle where the partial DRX active period is located, based on the definition of the remaining time of the DRX cycle.

It should be noted that, the first preset condition may be specified in the communication protocol, or may be preconfigured by the network device to the terminal device, which is not specifically limited in this embodiment of the present application.

340, if the first preset condition is not satisfied when the first message is received, the terminal device is in the sleep state in a first period of time after the first message is received.

If the first message does not meet the first preset condition when the first message is received, the first message is used for indicating that the terminal equipment is in the dormant state in a first time period after the first message is received, and the terminal equipment can be in the dormant state in 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 a fourth implementation form of the first preset condition hereinafter, it is understood that the first preset condition includes two conditions, that is, the first message is received in a second period of time before the DRX duration, and the terminal device is in a sleep state in the second period of time. For another example, in the following implementation form two of the first preset condition, it may be 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 described above are described below with reference to the accompanying drawings.

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

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

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

The above-mentioned decision condition of the DRX active period may be understood as a condition for triggering the DRX active period, and specific meanings thereof may include any one of the two meanings that "the decision condition of the DRX active period only satisfies the DRX duration timer" described in the above three cases, which are not repeated herein for brevity.

If the first message is received and the first preset condition in the second implementation form is met, the terminal equipment in the DRX active period has no data to send and no data to receive in the DRX active period because the terminal equipment only has the DRX duration timer. In this case, in order to reduce the power of the terminal device, the terminal device may be controlled to be in a sleep state for the remaining period of time through the first message.

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

In the first and second embodiments, the timer in the timing state in the terminal device may be adjusted to a non-timing state, so that the terminal device may enter the sleep state. For example, in the case where only the DRX duration timer counts, the DRX duration timer may be adjusted to a non-clocked state to cause the terminal device to enter a sleep state.

With the first and second implementation manners, it may be defined that, when the first message is received within the DRX duration, the terminal device is controlled to be in a sleep state for the remaining period or the first period. In combination with the third and fourth implementations, it is defined that the terminal device is controlled to be in the sleep state for the remaining period or the first period when the first message is received before the DRX duration.

In implementation form three, the first message is received within a second period of time prior to the DRX duration.

The second period of time may be located before the DRX duration, and may include that the second period of time may be located in a DRX cycle in which the DRX duration is located, or that 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 and the DRX duration are located in the same DRX cycle, the second period may be located in a start offset period of the DRX duration, referring to fig. 5, in the DRX cycle 520, the DRX duration may not be located at the beginning of the DRX cycle, i.e., an offset period existing between the start time of the DRX duration and the start time of the DRX cycle is the start offset period 530.

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

In a fourth implementation, the first message is received in a second period of time before the DRX duration, and the terminal device is in a sleep state in the second period of time.

It should be noted that, the relative position of the second period and the DRX duration in the fourth implementation form may be referred to the related description in the third implementation form, which is not described herein for brevity.

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

Accordingly, if the terminal device is in an active state for the second period, it is indicated that the data to be transmitted in the last DRX cycle (410) is not transmitted, and therefore, in this case, in order to avoid extending the delay of the communication between the terminal device and the network device, the terminal device may be controlled to be in a dormant state for the first period by the first message.

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

Optionally, the configuration parameters for configuring the second time include at least one of the following parameters: the second time period is at a time position of the DRX cycle, the time position of the second time period relative to the DRX duration, the time length of the second time period, a resource configuration of a tracking reference signal (tracking reference signal, TRS) within the second time 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 time period. Wherein, the CSI-RS may be a CSI-RS for beam training.

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

The 4 preset conditions may be used individually or in combination as the first preset condition. For example, the fourth preset condition may be combined with the second preset condition to be used as the first preset condition, when the first message is satisfied and the terminal device is in the sleep state in the second time period before the DRX duration, the timing of the DRX duration timer is only satisfied in the decision condition of the DRX active period, so that the terminal device can be ensured to complete data transmission with the network device in the last DRX cycle, and the DRX cycle in which the DRX active period is located does not need to transmit data with the network device, at this time, the terminal device can be controlled to be in the sleep state in the DRX cycle in which the DRX active period is located by the first message, that is, the terminal device can be in the sleep state in the whole DRX cycle, so as to save the electric quantity of the terminal device to the maximum extent.

The first message of the embodiment of the present application may multiplex various indication information in the current communication protocol, for example, the GTS message or WUS message described above, which is used to help the terminal device save power. In the multiplexing manner, the GTS message may be indicated by the target indication information carried in the GTS message to control whether the terminal device is in the sleep state in a manner specified in the conventional communication protocol (for example, in the first manner or the second manner described above), or to control the terminal device to be in the sleep state based on the manner in the embodiment of the present application (i.e., the manner described in fig. 3). That is, the target indication information carried in the GTS is used to indicate that the GTS message controls the terminal device to be in the sleep 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 second introduction manner, when the terminal device is controlled to be in the sleep state through the GTS message, the corresponding first duration of the first duration may be selected from a plurality of configured durations, and different durations in the plurality of durations correspond to different indexes, and when the GTS message carries the index corresponding to the first duration, the GTS message is instructed to control the terminal device to be in the sleep state according to the manner of the embodiment of the present application.

In addition to indicating that the GTS message is in a dormant state based on the method of the embodiment of the present application by means of the target indication information, it may also be determined by the terminal device autonomously whether the GTS message is in a dormant state based on the method of the embodiment of the present application. For example, when the network device configures the GTS parameter only for the terminal device through RRC signaling and does not configure the WUS parameter, 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 control the terminal device to be in the sleep state based on the method of the embodiment of the present application in either the GTS message or the WUS. The embodiments of the present application are not limited in this regard.

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 of the terminal device, another embodiment of the present application provides a method for transmitting a first message. A method for 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 through 720.

And 710, the terminal equipment detects a first message sent by the network equipment on a first time domain resource, wherein the first time domain resource and a second time domain resource occupied by PDCCH detection are positioned 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 resources have partial symbols that are identical.

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

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

The time threshold value in the second preset condition may be different in different cases, or may be the same as the embodiment of the present application, which is not limited thereto.

The time threshold may be expressed in terms of the number of symbols, and may refer to 2 symbols when the time threshold is 2, for example. The time threshold may also be expressed in absolute time, for example, 2 milliseconds when the time threshold is 2. The embodiments of the present application are not limited.

It should be noted that, the above-mentioned time threshold may be specified by a protocol, or may be configured in advance for the terminal device by the network device, for example, the network device may instruct the terminal device in a semi-static manner through RRC signaling, which is not limited in the 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 PDCCH configuration parameters to the terminal device by sending a system message or an RRC message, where the PDCCH configuration parameters include a control resource set (CORESET), a search space (search space), and the like, and the second time domain resource is determined by the CORESET and the search space together.

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

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

It should be noted that, the first message may be carried by the PDCCH, or may be transmitted separately, or may be carried by other signaling, which is not limited in the embodiment of the present application. If the first message is not carried by the PDCCH, the time domain resource (i.e., the first time domain) for transmitting the first message and the time domain resource (the second time domain resource) occupied by the PDCCH detection may also satisfy the above positional relationship, i.e., the first time domain resource and the second time domain resource are located in the same time slot. In particular, the positional relationship between the first time domain resource and the second time domain resource may be determined by the above-mentioned time threshold. For example, the first time domain resource and the second time domain resource satisfy any one of the following second preset conditions: the time difference between the starting symbol of the first time domain resource and the starting symbol of the second time domain resource is less than or equal to a time threshold, the time difference between the ending symbol of the first time domain resource and the ending symbol of the second time domain resource is less than or equal to a time threshold, the time difference between the ending symbol of the first time domain resource and the starting symbol of the second time domain resource is less than or equal to a time threshold, and the time difference between the starting symbol of the first time domain resource and the 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 brevity, specific descriptions of the time threshold and the like may be referred to above, and will not be repeated here.

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 detecting 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 electric quantity.

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 be used alone with 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 may enter a sleep state at any one of the time slots after the reception of the first message. Accordingly, when the method shown in fig. 7 is used alone, the method may be used in combination with or completely separate from the DRX mechanism specified in the current protocol, which is not limited in this embodiment of the present application. When the method shown in fig. 3 described above 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 slot or the remaining time slot.
