Background

A Non-Terrestrial Network (NTN) refers to a communication Network between a terminal device and a satellite (which may also be referred to as a Network device).

In an actual application process, in order to reduce power consumption of the terminal device, the terminal device may monitor a Physical Downlink Control Channel (PDCCH) discontinuously. Currently, a network device generally configures a Discontinuous Reception (DRX) -Hybrid Automatic Repeat Request (HARQ) -Round Trip Time (RTT) timer for a terminal device, and the terminal device does not monitor a PDCCH during the run of the DRX-HARQ-RRT timer.

However, in the NTN system, if the length of the configured drx-HARQ-RRT timer is smaller than the round trip transmission time signal transmission delay of the network device at the terminal device, the terminal device may prematurely start to monitor the PDCCH for scheduling retransmission, which increases the terminal energy consumption; if the length of the configured drx-HARQ-RRT timer is greater than the round-trip transmission time signal transmission delay of the network device at the terminal device, the time for the terminal device to start monitoring the PDCCH for scheduling retransmission is too late, which may cause the terminal device to miss the PDCCH, thereby affecting the scheduling performance.

Detailed Description

For ease of understanding, first, the concepts related to the present application will be explained.

The terminal equipment: the device has a wireless transceiving function. The terminal equipment can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a wearable terminal device, and the like. The terminal device according to the embodiment of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus. The terminal equipment may also be fixed or mobile.

A network device: the device is a device with wireless transceiving function deployed in the air. The network device may have a mobile nature, i.e. the network device may be a mobile device. Alternatively, the network device may be a satellite, balloon station. For example, the satellite may be a Low Earth Orbit (LEO) satellite, a Medium Earth Orbit (MEO) satellite, a geosynchronous Orbit (GEO) satellite, a High Elliptic Orbit (HEO) satellite, and the like. For example, LEO satellites typically have orbital altitudes ranging from 500km to 1500km, and orbital periods (periods of rotation around the earth) of about 1.5 hours to 2 hours. The signal propagation delay of the inter-user single-hop communication is about 20ms, and the inter-user single-hop communication delay refers to the transmission delay from the terminal equipment to the network equipment or the delay from the network equipment to the transmission equipment. The maximum satellite visibility time is about 20 minutes, which is the longest time that the beam of the satellite covers a certain area of the ground, and the LEO satellite moves relative to the ground, and the ground area covered by the LEO satellite changes as the satellite moves. The LEO satellite has short signal propagation distance, less link loss and low requirement on the transmitting power of terminal equipment. The GEO satellite typically has an orbital altitude of 35786km and an orbital period of 24 hours. The signal propagation delay for inter-user single-hop communications is approximately 250 ms. In order to ensure the coverage of the satellite and increase the system capacity of the communication network, the satellite may cover the ground by multiple beams, for example, one satellite may form tens or hundreds of beams to cover the ground, and one beam may cover a ground area having a diameter of tens to hundreds of kilometers.

Next, a description will be given of a scenario to which the communication method according to the present application is applied, with reference to fig. 1.

Fig. 1 is a schematic diagram of a communication scenario provided in an embodiment of the present application. Referring to fig. 1, a network device 101 and a terminal device 102 are included, and wireless communication can be performed between the network device 101 and the terminal device 102. The network comprising network device 101 and terminal device 102 may also be referred to as an NTN.

In an actual application process, in order to reduce power consumption of the terminal device, the terminal device may monitor the PDCCH discontinuously. DRX cycles (DRX cycles) may be preset by the network device, one DRX cycle including an active period (On Duration) and an inactive period. The terminal equipment monitors the PDCCH in the active period, and the terminal equipment does not monitor the PDCCH in the inactive period. Next, the DRX cycle will be described with reference to fig. 2. Fig. 2 is a schematic diagram of a DRX cycle according to an embodiment of the present disclosure. Referring to fig. 2, the DRX cycle includes an active period and an inactive period.

The network device may configure DRX configuration parameters for the terminal device, and the terminal device may monitor the PDCCH discontinuously according to the DRX configuration parameters. In the following, the DRX configuration parameters may include one or more of the following parameters:

drx Duration Timer (drx-on Duration Timer): refers to a period of time that lasts at the beginning of the DRX cycle. The DRX duration timer is started at the DRX start time offset after the start of one DRX cycle. Optionally, the terminal device may determine the time for starting the DRX duration timer according to a currently used DRX cycle (DRX short cycle or DRX long cycle). For example, if the DRX cycle currently used by the terminal device is a short cycle and the current subframe satisfies: [ (SFN × 10) + subframe identity (subframe number) ]% DRX short cycle — DRX start time offset% DRX short cycle, then start DRX duration timer. If the DRX period currently used by the terminal equipment is a long period and the current subframe meets the following conditions: when [ (SFN × 10) + subframe id ]% DRX long cycle ═ DRX start time offset, then DRX duration timer is started. The drx duration timer is started at a time after the drx slot offset (drx-SlotOffset) slots from the start of the current subframe.

drx Slot Offset (drx-Slot Offset): refers to the time delay from the beginning of a subframe in the time slot of starting the drx duration timer in the subframe.

Drx Inactivity Timer (Drx-Inactivity Timer): refers to a period of time that lasts after receiving a PDCCH indicating uplink scheduling or downlink scheduling. If the terminal equipment receives a PDCCH indicating the initial transmission of the downlink or the uplink, the terminal starts or restarts the drx inactivity timer.

Downlink (DL) drx hybrid automatic repeat request (HARQ) Round Trip Time (RTT) Timer (drx-HARQ-RTT-Timer DL): refers to the shortest waiting time before downlink HARQ retransmission. Besides the broadcast process, one downlink HARQ process corresponds to one downlink drx-HARQ-RTT timer. If the terminal device receives a PDCCH indicating downlink transmission, or if the terminal device receives a Media Access Control (MAC) Protocol Data Unit (PDU) on the configured downlink grant resource, the terminal starts a downlink drx-HARQ-RTT timer corresponding to the HARQ process after completing transmission of HARQ process feedback for the current downlink transmission, and stops a downlink drx retransmission timer corresponding to the HARQ process.

Starting time offset of downlink drx-HARQ-RTT timer: refers to a period of time that is offset before the downlink drx-HARQ-RTT timer starts. The starting time offset of the downlink drx-HARQ-RTT timer is usually positive, i.e. the start of the downlink drx-HARQ-RTT timer is delayed.

Uplink (UL) drx-HARQ-RTT Timer (drx-HARQ-RTT-Timer UL): refers to the shortest duration of waiting before uplink HARQ retransmission. One uplink HARQ process corresponds to one uplink drx-HARQ-RTT timer. If the terminal equipment receives a PDCCH indicating uplink transmission or if the terminal sends a MAC PDU on the configured uplink authorized resource, the terminal starts an uplink drx-HARQ-RTT Timer corresponding to the HARQ process after finishing the uplink transmission, and stops an uplink drx Retransmission Timer (UL) corresponding to the HARQ process.

Starting time offset of uplink drx-HARQ-RTT timer: refers to a period of time that is offset before the uplink drx-HARQ-RTT timer starts. The starting time offset of the uplink drx-HARQ-RTT timer is usually a positive number, i.e. the start of the uplink drx-HARQ-RTT timer is delayed.

Downlink drx Retransmission Timer (drx-Retransmission Timer DL): refers to the longest duration of time before receiving the downlink retransmission. Besides the broadcast process, each downlink HARQ process corresponds to one drx downlink retransmission timer. If the downlink drx-HARQ-RTT timer corresponding to a certain HARQ of the terminal equipment is overtime and the downlink data transmitted by using the HARQ process is unsuccessfully decoded, the terminal starts the downlink drx retransmission timer corresponding to the HARQ process.

Uplink drx Retransmission Timer (drx-Retransmission Timer UL): refers to the longest duration of time before receiving the uplink retransmission. Each uplink HARQ process corresponds to one drx downlink retransmission timer. And if the uplink drx-HARQ-RTT timer corresponding to a certain HARQ of the terminal equipment is overtime, the terminal starts the uplink drx retransmission timer corresponding to the HARQ process.

drx Long Cycle Start Offset (drx-Long Cycle Start Offset): the long drx period and the drx long period start time offset define the sub-frame where the long drx period and the short drx period start.

drx Short Cycle (drx-Short Cycle): meaning a short drx cycle.

drx Short Cycle Timer (drx-Short Cycle Timer): the duration of the short DRX cycle the terminal device should follow.

In practical application, the DRX active period includes the following cases, i.e. the active period of the DRX cycle in the following cases:

case 1: the active period of the DRX cycle is when any one of the following 5 timers is in a running state, the 5 timers including: a drx duration Timer, a drx inactivity Timer, a downlink drx retransmission Timer, an uplink drx retransmission Timer, and a Random Access-Contention Resolution Timer (Random Access-Contention Resolution Timer).

Case 2: the terminal device transmits a Scheduling Request (SR) on a Physical Uplink Control Channel (PUCCH), and is in a waiting state.

Case 3: in the contention-based random access process, the terminal does not receive primary initial transmission of a Cell Radio Network Temporary identity (C-RNTI) scrambled PDCCH indication after successfully receiving a random access response.

In the practical application process, the terminal device does not monitor the PDCCH during the running period of the drx-HARQ-RTT timer (uplink drx-HARQ-RTT timer or downlink drx-HARQ-RTT timer) and the offset period of the starting time of the drx-HARQ-RTT timer (uplink drx-HARQ-RTT timer or downlink drx-HARQ-RTT timer). And the terminal starts monitoring the uplink retransmission scheduling after the timer is overtime or determines whether to start monitoring the downlink retransmission scheduling according to the feedback condition. Note that, at the same time, if any one of the 5 timers shown in the above case 1 is in an active state and the drx-HARQ-RTT timer is also in an active state, the terminal device monitors the PDCCH.

In the related technology, the terminal device does not monitor the PDCCH only during the running period of the drx-HARQ-RRT timer, and the network device configures the timer length of the drx-HARQ-RRT timer for the terminal device, if the configured timer length of the drx-HARQ-RRT timer is less than the signal transmission delay, the terminal device will be caused to monitor the PDCCH for scheduling retransmission too early, and the energy consumption of the terminal device is increased; if the timer length of the configured drx-HARQ-RRT timer is greater than the signal transmission delay, the time for the terminal device to start monitoring the PDCCH for scheduling retransmission is too late, which may cause the terminal device to miss detection of the PDCCH, thereby affecting the scheduling performance.

In order to solve the above technical problem, embodiments of the present application provide a communication method, which may determine first information for adjusting a drx-HARQ-RRT timer of a terminal device according to motion information of the terminal device and motion information of a network device, because the first information is related to the motion information of the terminal device and the network device, the drx-HARQ-RRT timer of the terminal device can be accurately adjusted according to the first information, so that the time length for which the terminal equipment does not monitor the PDCCH is matched with the signal transmission time delay between the terminal equipment and the network equipment, the problem of higher power consumption of the terminal caused by the time length for which the PDCCH is not monitored is less than the signal transmission time length is solved, and reduce the problem of missed detection of the PDCCH due to the fact that the time length for not monitoring the PDCCH is longer than the signal transmission time length, the power consumption of the terminal equipment is low, and the performance of the network equipment for scheduling the terminal equipment is high.

In the present application, the term "timer length" or "length of timer" has the same meaning, and means a duration of the timer, and the term "timer length" or "length of timer" may also be referred to as "time window length of timer", "duration of timer", or the like. In other words, the timer expires after a certain time period (the time period is the length of the timer) has elapsed after the timer is started.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and description of the same or similar contents is not repeated in different embodiments.

Fig. 3 is a flowchart illustrating a communication method according to an embodiment of the present application. Referring to fig. 3, the method may include:

s301, the terminal device acquires first information corresponding to the drx-HARQ-RRT timer.

The first information is determined by the terminal equipment or the network equipment according to the motion information of the terminal equipment and the motion information of the network equipment.

The drx-HARQ-RRT timer may comprise one or more of an uplink drx-HARQ-RRT timer or a downlink drx-HARQ-RRT timer. If the drx-HARQ-RRT timer includes the uplink drx-HARQ-RRT timer and the downlink drx-HARQ-RRT timer, the terminal device may obtain first information corresponding to the uplink drx-HARQ-RRT timer and first information corresponding to the downlink drx-HARQ-RRT timer, respectively.

In an actual application process, the first information is sent to the terminal device by the network device, in other words, the network device determines the first information according to the motion information of the terminal device and the motion information of the network device, and sends the first information to the terminal device. Or the first information is determined by the terminal device according to the motion information of the terminal device and the motion information of the network device, in other words, the terminal device determines the first information according to the motion information of the terminal device and the motion information of the network device. Or, a part of the first information is sent by the network device to the terminal device, and another part of the first information is determined by the terminal device according to the motion information of the terminal device and the motion information of the network device, in other words, the terminal device may receive a part of information from the network device, and the terminal device may determine another part of information according to the motion information of the terminal device and the motion information of the network device, where the first information includes the part of information and the another part of information. For example, one part of the information may be the first timer length, and the other part of the information may be the first adjustment information.

The motion information of the terminal device comprises the motion speed and the motion direction of the terminal device in a first preset time period. The motion information of the network device comprises the motion speed and the motion direction of the network device in a second preset time period. The first preset time period and the second preset time period are respectively a time period before the current time, and the first preset time period and the second preset time period may be the same.

The first information may comprise a first timer length and/or first adjustment information, or the first information may comprise a first start time offset and/or second adjustment information. When the contents included in the first information are different, the process of determining the first information according to the motion information of the terminal device and the motion information of the network device is also different, and hereinafter, the process of determining the first information when the first information includes different contents will be described separately.

One possible implementation: the first information includes a first timer length and/or first adjustment information.

The first adjustment information comprises a first adjustment period and a first adjustment step length. The first adjustment period is a period for adjusting the timer length of the drx-HARQ-RRT timer, that is, the timer length of the drx-HARQ-RRT timer is adjusted according to the first adjustment period. The first adjustment step is a step for adjusting the timer length of the drx-HARQ-RRT timer, that is, the timer length of the drx-HARQ-RRT timer is adjusted according to the first adjustment step.

In this feasible implementation manner, the distance change condition between the terminal device and the network device may be determined according to the motion information of the terminal device and the motion information of the network device, where the distance change condition between the terminal device and the network device is: constant distance, increasing distance, and decreasing distance.

If the distance between the terminal device and the network device is not changed, the signal transmission delay between the terminal device and the network device is not changed, it can be determined that the first timer length can be the same as the current timer length, the first adjustment step length is 0, and the first adjustment period can be a preset maximum value.

If the distance between the terminal device and the network device is decreased, the signal transmission delay between the terminal device and the network device is decreased, and it may be determined that the first timer length is smaller than the current timer length, for example, a first corresponding relationship between the distance between the terminal device and the network device and the timer length may be preset, and correspondingly, the first timer length may be determined according to the distance between the terminal device and the network device and the first corresponding relationship. The first adjustment step size is a negative number, and may be determined according to the first timer length and the current timer length. If the distance between the terminal device and the network device is rapidly decreased, the first adjustment period is smaller, and if the distance between the terminal device and the network device is slowly decreased, the first adjustment period is larger, for example, a second corresponding relationship between the distance change speed between the terminal device and the network device and the adjustment period may be preset, and correspondingly, the first adjustment period may be determined according to the distance change speed between the terminal device and the network device and the second corresponding relationship.

If the distance between the terminal device and the network device is increased, the signal transmission delay between the terminal device and the network device is increased, it can be determined that the first timer length is greater than the current timer length, the first adjustment step length is a positive number, if the distance between the terminal device and the network device is rapidly decreased, the first adjustment period is smaller, and if the distance between the terminal device and the network device is slowly decreased, the first adjustment period is larger.

It should be noted that the above illustrates the manner of determining the first information according to the motion information of the terminal device and the motion information of the network device by way of example only, and the manner of determining the first information according to the motion information of the terminal device and the motion information of the network device is not limited.

Another possible implementation: the first information comprises a first start time offset and/or second adjustment information.

The second adjustment information includes a second adjustment period and a second adjustment step size. The second adjustment period is a period for adjusting the offset of the starting time of the drx-HARQ-RRT timer, that is, the offset of the starting time of the drx-HARQ-RRT timer is adjusted according to the first adjustment period. The second adjustment step is a step for adjusting the offset of the starting time of the drx-HARQ-RRT timer, that is, the offset of the starting time of the drx-HARQ-RRT timer is adjusted according to the second adjustment step.

If the distance between the terminal device and the network device does not change, the signal transmission delay between the terminal device and the network device does not change, it can be determined that the first start time offset may be the same as the current start time offset, the second adjustment step length is 0, and the second adjustment period may be a preset maximum value.

If the distance between the terminal device and the network device becomes smaller, the signal transmission delay between the terminal device and the network device becomes smaller, and it can be determined that the first start time offset is smaller than the current start time offset. The first adjustment step is negative. If the distance between the terminal device and the network device is rapidly decreased, the second adjustment period is smaller, and if the distance between the terminal device and the network device is slowly decreased, the second adjustment period is larger.

If the distance between the terminal device and the network device is increased, the signal transmission delay between the terminal device and the network device is increased, it can be determined that the first starting time offset is greater than the current starting time offset, the first adjustment step length is a positive number, if the distance between the terminal device and the network device is rapidly decreased, the second adjustment period is smaller, and if the distance between the terminal device and the network device is slowly decreased, the second adjustment period is larger.

S302, the terminal equipment adjusts a drx-HARQ-RRT timer of the terminal equipment according to the first information.

The manner of adjusting the drx-HARQ-RRT timer of the terminal device according to the first information is also different when the first information includes different contents, and the manner of adjusting the drx-HARQ-RRT timer of the terminal device according to the first information when the first information includes different contents will be described below.

And when the first information comprises the first timer length and/or the first adjustment information, the terminal equipment adjusts the length of the drx-HARQ-RRT timer of the terminal equipment according to the first information.

If the first information comprises the first timer length, the terminal equipment adjusts the length of the drx-HARQ-RRT timer of the terminal equipment to the first timer length.

If the first information comprises first adjustment information, the terminal equipment periodically adjusts the current length of the drx-HARQ-RRT timer through a first adjustment step according to a first adjustment period.

If the first information comprises the length of the first timer and the first adjustment information, the terminal equipment adjusts the length of the drx-HARQ-RRT timer of the terminal equipment to the length of the first timer, and periodically adjusts the current length of the drx-HARQ-RRT timer according to a first adjustment period and a first adjustment step length.

This possible implementation is described below with reference to fig. 4.

Fig. 4 is a schematic diagram of adjusting a drx-HARQ-RRT timer according to an embodiment of the present disclosure. Referring to fig. 4, it is assumed that the starting time of the current drx-HARQ-RRT timer of the terminal device is t1, the timer length is t2-t1, and the timeout time of the drx-HARQ-RRT timer is t3, in which case, the terminal device does not monitor the PDCCH between time t1 and time t 2. Assuming that the adjusted timer length t3-t1 and t3 of the drx-HARQ-RRT timer is greater than t2, after the timer length of the drx-HARQ-RRT timer is adjusted, the starting time of the drx-HARQ-RRT timer is still t1 and the timeout time is t3, in which case, the terminal device does not monitor the PDCCH between time t1 and time t 3.

In the possible implementation manner, the time length that the terminal device does not monitor the PDCCH is changed by changing the timer length of the drx-HARQ-RRT timer.

And when the first information comprises the offset of the starting time of the first timer and/or the second adjustment information, the terminal equipment adjusts the offset of the starting time of the drx-HARQ-RRT timer of the terminal equipment according to the first information.

And if the first information comprises the first starting time offset, the terminal equipment adjusts the starting time offset of the drx-HARQ-RRT timer of the terminal equipment to the first starting time offset.

And if the first information comprises second adjustment information, the terminal equipment periodically adjusts the current starting time offset of the drx-HARQ-RRT timer through a second adjustment step according to a second adjustment period.

If the first information comprises a first starting time offset and/or second adjustment information, the terminal equipment adjusts the starting time offset of the drx-HARQ-RRT timer of the terminal equipment to the first starting time offset, and periodically adjusts the current starting time offset of the drx-HARQ-RRT timer through a second adjustment step according to a second adjustment period.

This possible implementation is described below with reference to fig. 5.

Fig. 5 is a schematic diagram of another exemplary method for adjusting a drx-HARQ-RRT timer according to the embodiment of the present disclosure. Referring to fig. 5, assuming that the offset of the starting time of the current drx-HARQ-RRT timer of the terminal device is 1, and the initial starting time of the drx-HARQ-RRT timer is t1, the drx-HARQ-RRT timer is started after the offset of the starting time is 1 at time t1, in which case, the terminal device does not monitor the PDCCH between time t1 and time t 3. Assuming that the starting time offset of the adjusted drx-HARQ-RRT timer is the starting time offset 2, since the initial starting time of the drx-HARQ-RRT timer is t1, the drx-HARQ-RRT timer starts after the starting time offset 2 passes at time t1, in which case the terminal device does not monitor the PDCCH between time t1 and time t 5.

In this possible implementation manner, by changing the starting time of the drx-HARQ-RRT timer, the duration that the terminal device does not monitor the PDCCH is changed.

According to the communication method provided by the embodiment of the application, the terminal equipment firstly acquires the first information corresponding to the drx-HARQ-RRT timer, and then adjusts the drx-HARQ-RRT timer according to the first information. Because the first information is related to the motion information of the terminal equipment and the network equipment, the drx-HARQ-RRT timer of the terminal equipment can be accurately adjusted according to the first information, so that the time length for which the terminal equipment does not monitor the PDCCH is matched with the signal transmission time delay between the terminal equipment and the network equipment, the problem that the power consumption of the terminal is higher due to the fact that the time length for which the PDCCH is not monitored is smaller than the signal transmission time length is solved, the problem that the PDCCH is missed to be detected due to the fact that the time length for which the PDCCH is not monitored is larger than the signal transmission time length is solved, the power consumption of the terminal equipment is lower, and the performance for scheduling the terminal equipment by the network equipment is higher.

In an actual application process, when the content included in the first information is different or it is determined that the execution subject (network device or terminal device) of the first information is different, the communication process may be different, and several possible communication methods are described below with reference to fig. 6 to 11.

Next, a communication method is described with reference to fig. 6, where in the embodiment shown in fig. 6, the network device determines first information corresponding to the uplink drx-HARQ-RRT timer, where the first information includes a first timer length and first adjustment information, and the terminal device periodically adjusts the timer length of the uplink drx-HARQ-RRT timer according to the first information.

Fig. 6 is a flowchart illustrating another communication method according to an embodiment of the present application. Referring to fig. 6, the method may include:

s601, the network equipment acquires the motion information of the terminal equipment and the motion information of the network equipment.

Optionally, the terminal device may send the motion information of the terminal device to the network device.

Alternatively, the embodiment shown in fig. 6 may be performed after the network device and the terminal device establish Radio Resource Control (RRC) connection.

S602, the network equipment determines first information corresponding to an uplink drx-HARQ-RRT timer of the terminal equipment according to the motion information of the terminal equipment and the motion information of the network equipment.

The first information comprises a first timer length and first adjustment information, and the first adjustment information comprises a first adjustment period and a first adjustment step length.

It should be noted that the process of executing S602 may refer to the process of determining the first information described in S301, and is not described herein again.

S603, the network equipment sends the first information to the terminal equipment.

Optionally, the network device may send the first information to the terminal device through a feasible implementation manner as follows:

one possible implementation is:

the network equipment sends RRC to the terminal equipment, and the RRC signaling comprises first information.

For example, the RRC signaling may be an RRC reconfiguration message.

Another possible implementation:

the network device transmits a MAC Control Element (CE) to the terminal device, the MAC CE including the first information.

Yet another possible implementation:

and the network equipment sends a PDCCH for indicating uplink scheduling to the terminal equipment, wherein the PDCCH for indicating the uplink scheduling comprises the first information.

It should be noted that, when the drx-HARQ-RRT timer is the downlink drx-HARQ-RRT timer, the network device sends a PDCCH indicating downlink scheduling to the terminal device, and the PDCCH indicating downlink scheduling includes the first information.

In this feasible implementation manner, the network device can transmit the first information to the terminal device without transmitting an additional signaling to the terminal device, so that the signaling overhead is relatively low.

S604, the terminal equipment adjusts the timer length of the uplink drx-HARQ-RRT timer to be the first timer length.

The terminal device locally stores the timer length of the uplink drx-HARQ-RRT timer, and the terminal device can directly modify the locally stored timer length of the uplink drx-HARQ-RRT timer to the first timer length.

It should be noted that, when the first information includes the first start time offset and the second adjustment information, this step may be replaced by: and the terminal equipment adjusts the offset of the starting time of the uplink drx-HARQ-RRT timer to the first offset of the starting time.

S605, the terminal equipment periodically adjusts the timer length of the uplink drx-HARQ-RRT timer according to the first adjustment period and the first adjustment step.

Optionally, after the terminal device adjusts the timer length of the uplink drx-HARQ-RRT timer to the first timer length, after a first adjustment period elapses, the terminal device updates the timer length of the uplink drx-HARQ-RRT timer to: and the current timer length of the uplink drx-HARQ-RRT timer + the first adjustment step. After a first adjustment period, the terminal device updates the timer length of the uplink drx-HARQ-RRT timer to: and the current timer length of the uplink drx-HARQ-RRT timer + the first adjustment step. And so on.

In the actual application process, the motion conditions of the network device and the terminal device may change at any time, and therefore, in order to enable the time length that the terminal device does not monitor the PDCCH to be matched with the signal transmission delay between the terminal device and the network device, the network device may periodically acquire the motion information of the terminal device and the motion information of the network device, determine new first information corresponding to the uplink drx-HARQ-RRT timer of the terminal device according to the motion information of the terminal device and the motion information of the network device, and send the new first information to the terminal device, so that the terminal device adjusts the timer length of the uplink drx-HARQ-RRT timer according to the new first information. Optionally, the new first information may include the first adjustment information, or the new first information may include the first timer length and the first adjustment information. The first timer length included in the new first information and the first timer length included in the first information in S602 may be different, and the first adjustment information included in the new first information and the first adjustment information included in the first information in S602 may be different. And after the terminal equipment receives the new first information, the terminal equipment adjusts the timer length of the uplink drx-HARQ-RRT timer according to the new first information.

Optionally, if the new first information received by the terminal device includes the first timer duration and the first adjustment information, the terminal device may adjust the timer length of the uplink drx-HARQ-RRT timer according to the manner shown in S604-S605.

Optionally, if the new first information received by the terminal device includes the first adjustment information, the terminal device may determine a first time first, and adjust the timer length of the uplink drx-HARQ-RRT timer of the terminal device according to the new first information at the first time. The first time may be a time when the terminal device acquires the new first information, or the first time is a time after the second time, a time difference between the first time and the second time is a first adjustment period in the new first information, and the second time is a time when the terminal device adjusts the length of the drx-HARQ-RRT timer or the offset of the start time last time. And if the time difference between the first time and the second time is greater than the first adjusting period in the new first information, the first time is the current time.

It should be noted that, when the first information includes the first start time offset and the second adjustment information, this step may be replaced by: and the terminal equipment periodically adjusts the offset of the starting time of the uplink drx-HARQ-RRT timer according to the second adjustment period and the second adjustment step length.

And S606, the terminal equipment performs DRX operation according to the uplink DRX-HARQ-RRT timer.

And the terminal equipment performs DRX operation according to the latest uplink DRX-HARQ-RRT timer.

The terminal device may perform uplink DRX operation according to the uplink DRX-HARQ-RRT timer, for example, after completing the uplink transmission, the terminal device starts the uplink DRX-HARQ-RTT timer corresponding to the HARQ process, and stops the uplink DRX retransmission timer corresponding to the HARQ process, where a timer length of the uplink DRX-HARQ-RTT timer is a last updated timer length of the terminal device. And when the uplink drx-HARQ-RTT timer is overtime, the terminal starts the uplink drx timer corresponding to the HARQ process.

The terminal device may perform downlink DRX operation according to the downlink DRX-HARQ-RRT timer, for example, after the terminal device completes transmission of HARQ process feedback for the current downlink transmission, start a downlink DRX-HARQ-RTT timer corresponding to the HARQ process, and simultaneously stop a downlink DRX retransmission timer corresponding to the HARQ process, where a timer length of the downlink DRX-HARQ-RTT timer is a last updated timer length of the terminal device. When the downlink drx-HARQ-RTT timer is overtime, if the terminal equipment fails to decode the downlink data transmitted by using the HARQ process, the terminal equipment starts the downlink drx retransmission timer corresponding to the HARQ process.

It should be noted that, when the first information includes the first start time offset and the second adjustment information, the communication process between the terminal device and the network device may be similar to the communication process shown in fig. 6, and is not described herein again.

It should be further noted that, for the downlink drx-HARQ-RTT timer, a communication process between the terminal device and the network device is similar to the communication process shown in fig. 6, and details are not repeated here.

In the embodiment shown in fig. 6, the network device determines, according to the motion information of the terminal device and the motion information of the network device, that the uplink drx-HARQ-RRT timer corresponds to the first information, and sends the first information to the terminal device, so that the terminal device adjusts the timer length of the uplink drx-HARQ-RRT timer according to the first information. The first information is related to the motion information of the terminal device and the network device, so that the terminal device can accurately adjust the timer length of the uplink drx-HARQ-RRT timer of the terminal device according to the first information. The first information further includes first adjustment information, so that the terminal device can periodically adjust the timer length of the uplink drx-HARQ-RRT timer according to the first adjustment information, that is, the network device sends the first information to the terminal device once, that is, the terminal device can adjust the timer length of the uplink drx-HARQ-RRT timer multiple times according to the first information, so that the signaling overhead is relatively low.

Next, with reference to fig. 7, a detailed description will be given of a communication method shown in the embodiment of fig. 6 by way of a specific example. Fig. 7 is a schematic diagram of a communication process according to an embodiment of the present application.

After the network device and the terminal device establish RRC connection, the network device obtains motion information of the terminal device and the network device within a period of time before the current time, and determines first information corresponding to the uplink drx-HARQ-RRT timer according to the motion information, assuming that the first information includes a first timer length L1, a first adjustment period T1, and a first adjustment step d 1.

Referring to the timer length maintenance process in fig. 7, the timer length maintenance process of the uplink drx-HARQ-RRT timer by the terminal device is as follows:

the network device sends the first information to the terminal device at time t 1. And after the terminal equipment receives the first information, setting the timer length L of the uplink drx-HARQ-RRT timer to be L1. At time T3 after the elapse of time T1 from time T1, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+ d1, that is, adds d1 to the current timer length L1. At time T7 after the lapse of time duration T1 from time T3, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1, that is, adds d1 to the current timer length L1+ d 1.

Assume that the network device determines to obtain new first information at time T9, where the new first information includes the first adjustment period T2 and the first adjustment step d 2. At time T12 after the elapse of time T2 from time T7, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1+ d2, that is, adds d2 to the current timer length L1+2 × d 1. At time T16 after the lapse of time duration T2 from time T12, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1+2 × d2, that is, adds d2 to the current timer length L1+2 × d1+ d 2. And so on.

Referring to the DRX procedure in fig. 7, the procedure of the terminal device performing DRX operation according to the DRX-HARQ-RRT timer is as follows:

assuming that the time t1 to the time t11 is one DRX cycle, the terminal device starts a DRX duration timer at the time t1, and the DRX duration timer times out at the time t 4.

Assuming that the terminal device receives PDCCH1 sent by the network device at time t2, and PDCCH1 indicates that the initial transmission of uplink HARQ ID1 is scheduled, the terminal device starts a drx inactivity timer, which times out at time t 6.

Assuming that the terminal device completes uplink transmission of the HARQ ID1 at time t5, the terminal device starts an uplink drx-HARQ-RTT timer corresponding to the HARQ ID1 at time t5, and since the timer length of the uplink drx-HARQ-RRT timer at this time is L1+ d1, the uplink drx-HARQ-RRT timer is in an operating state within a time duration of L1+ d1 after time t5, and at time t8 after the time duration of L1+ d1 elapses from time t5, the uplink drx-HARQ-RRT timer corresponding to the HARQ ID1 times out, and starts the uplink drx retransmission timer.

Assuming that the terminal device receives PDCCH2 transmitted by the network device at time t10, PDCCH2 indicates scheduling of retransmission of uplink HARQ ID 1. Assuming that the terminal device completes retransmission at time t13, the terminal device stops the uplink drx retransmission timer at time t13, and starts the uplink drx-HARQ-RTT timer corresponding to HARQ ID1, because the timer length of the uplink drx-HARQ-RRT timer at this time is L1+2 × d1+ d2, the uplink drx-HARQ-RRT timer corresponding to HARQ ID1 is in an operating state within a time period L1+2 × d1+ d2 after time t13, and at time t15 after the time period L1+2 × d1+ d2 elapses from time t13, the uplink drx-HARQ-RTT timer corresponding to HARQ ID1 times out, and starts the uplink drx retransmission timer.

Assuming that the time t11 to the time t14 is one DRX cycle, the terminal device starts a DRX duration timer at the time t11, and the DRX duration timer times out at the time t 14.

Next, a communication method is described with reference to fig. 8, where in the embodiment shown in fig. 8, the network device determines first information corresponding to an uplink drx-HARQ-RRT timer of the terminal device, where the first information includes a first timer length, and the network device sends the first information to the terminal device through a PDCCH indicating uplink scheduling.

Fig. 8 is a flowchart illustrating another communication method according to an embodiment of the present application. Referring to fig. 8, the method may include:

s801, the network equipment acquires the motion information of the terminal equipment and the motion information of the network equipment.

S802, the network equipment determines first information corresponding to an uplink drx-HARQ-RRT timer of the terminal equipment according to the motion information of the terminal equipment and the motion information of the network equipment.

Wherein the first information includes a first timer length.

It should be noted that the execution processes of S801-S802 may refer to the execution processes of S601-S602, and are not described herein again.

S803, the network device sends a PDCCH indicating uplink scheduling to the terminal device.

The PDCCH for indicating uplink scheduling comprises first information.

It should be noted that, for the first information corresponding to the downlink drx-HARQ-RRT timer, the network device sends, to the terminal device, a PDCCH indicating downlink scheduling, where the PDCCH indicating downlink scheduling includes the first information corresponding to the downlink drx-HARQ-RRT timer.

In an actual application process, when the network device sends a PDCCH indicating uplink scheduling to the terminal device, the network device may not determine new first information corresponding to the uplink drx-HARQ-RRT timer (that is, the network device does not determine the first information corresponding to the uplink drx-HARQ-RRT timer between sending a PDCCH indicating uplink scheduling and sending a PDCCH indicating uplink scheduling this time), or the new first information corresponding to the uplink drx-HARQ-RRT timer determined by the network device is the same as the first information corresponding to the uplink drx-HARQ-RRT timer determined last time by the network device, and the network device may not carry the first information in the PDCCH when sending the PDCCH indicating uplink scheduling this time. Correspondingly, when the PDCCH indicating uplink scheduling received by the terminal device does not include the first information, the terminal device may not adjust the timer length of the uplink drx-HARQ-RRT timer.

It should be noted that, similar to the PDCCH indicating the uplink scheduling, the PDCCH indicating the downlink scheduling sent by the network device to the terminal device may not include the first information corresponding to the downlink drx-HARQ-RRT timer, and accordingly, the terminal device may not adjust the timer length of the downlink drx-HARQ-RRT timer.

S804, the terminal equipment adjusts the timer length of the uplink drx-HARQ-RRT timer to be the first timer length.

It should be noted that the execution process of S804 may refer to the execution process of S604, and is not described herein again.

In the actual application process, the motion conditions of the network device and the terminal device may change at any time, and therefore, in order to enable the time length that the terminal device does not monitor the PDCCH to be matched with the signal transmission delay between the terminal device and the network device, the network device may periodically acquire the motion information of the terminal device and the motion information of the network device, determine new first information corresponding to the uplink drx-HARQ-RRT timer of the terminal device according to the motion information of the terminal device and the motion information of the network device, and send the new first information to the terminal device, so that the terminal device adjusts the timer length of the uplink drx-HARQ-RRT timer according to the new first information. That is, the processes shown in S801-S804 may be performed periodically.

And S805, the terminal equipment performs DRX operation according to the uplink DRX-HARQ-RRT timer.

It should be noted that the execution process of S805 may refer to the execution process of S606, and details are not described here.

It should be noted that, when the first information includes the first start time offset, the communication process between the terminal device and the network device may be similar to the communication process shown in fig. 8, and details are not repeated here.

It should be further noted that, for the downlink drx-HARQ-RTT timer, a communication process between the terminal device and the network device is similar to the communication process shown in fig. 8, and details are not repeated here.

In the embodiment shown in fig. 8, the network device determines first information corresponding to the uplink drx-HARQ-RRT timer according to the motion information of the terminal device and the motion information of the network device, and sends the first information to the terminal device through a PDCCH indicating uplink scheduling. The first information is related to the motion information of the terminal device and the network device, so that the terminal device can accurately adjust the timer length of the uplink drx-HARQ-RRT timer of the terminal device according to the first information. The network equipment sends the first information to the terminal equipment through the PDCCH for indicating scheduling, and the network equipment can send the first information to the terminal equipment without sending extra signaling to the terminal equipment, so that the signaling overhead is low.

Next, the communication method shown in the embodiment of fig. 8 will be described in detail by specific examples with reference to fig. 9. Fig. 9 is a schematic diagram of another communication process provided in the embodiment of the present application.

The network device sends PDCCH1 to the terminal device at time t2, PDCCH1 indicates that the initial transmission of uplink HARQ ID1 is scheduled, and PDCCH1 includes the first information (the first information includes L1), then the terminal device starts drx inactivity timer, which times out at time t 5.

Assuming that the terminal device completes uplink transmission of the HARQ ID1 at time t4, the terminal device starts an uplink drx-HARQ-RTT timer corresponding to the HARQ ID1 at time t4, and since the timer length of the uplink drx-HARQ-RRT timer at this time is L1, the uplink drx-HARQ-RRT timer is in an operating state within a time length L1 after time t4, and at time t6 after the time L1 elapses from time t4, the uplink drx-HARQ-RRT timer corresponding to the HARQ ID1 times out and starts an uplink drx retransmission timer.

Before the time t7, the network device obtains the motion information of the terminal device and the network device within a period of time before the current time, and determines first information corresponding to the uplink drx-HARQ-RRT timer according to the motion information, assuming that the first information includes a first timer length L2. The network device transmits PDCCH2 to the terminal device at time t7, PDCCH2 indicates scheduling of retransmission of uplink HARQ ID1, and PDCCH2 includes first information (the first information includes L2). Assuming that the terminal equipment completes retransmission at the time t9, the terminal equipment stops the uplink drx retransmission timer at the time t9, starts the uplink drx-HARQ-RTT timer corresponding to the HARQ ID1, and since the timer length of the uplink drx-HARQ-RRT timer at this time is L2, the uplink drx-HARQ-RRT timer corresponding to the HARQ ID1 is in an operating state within the duration L2 after the time t9, and at the time t12 after the duration L2 elapses from the time t9, the uplink drx-HARQ-RTT timer corresponding to the HARQ ID1 times out, and starts the uplink drx retransmission timer.

Assuming that the time t8 to the time t15 is one DRX cycle, the terminal device starts a DRX duration timer at the time t8, and the DRX duration timer times out at the time t 11.

Assuming that the terminal device receives PDCCH3 sent by the network device at time t10, PDCCH3 indicates the initial transmission of HARQ ID2, and PDCCH3 does not include the first information, the terminal device starts drx inactivity timer, which times out at time t 13.

Assuming that the terminal device completes uplink transmission of the HARQ ID2 at time t14, the terminal device starts an uplink drx-HARQ-RTT timer corresponding to the HARQ ID2 at time t14, and since the timer length of the uplink drx-HARQ-RRT timer at this time is L2, the uplink drx-HARQ-RRT timer is in an operating state within a time length L2 after time t14, and at time t16 after the time L2 elapses from time t14, the uplink drx-HARQ-RRT timer corresponding to the HARQ ID2 times out and starts an uplink drx retransmission timer.

Next, a communication method is described with reference to fig. 10, where in the embodiment shown in fig. 10, the terminal device determines first information corresponding to the uplink drx-HARQ-RRT timer, where the first information includes first adjustment information, and the terminal device periodically adjusts the timer length of the uplink drx-HARQ-RRT timer according to the first information.

Fig. 10 is a flowchart illustrating another communication method according to an embodiment of the present application. Referring to fig. 10, the method may include:

s1001, the terminal equipment obtains the first timer length of the uplink drx-HARQ-RRT timer.

Optionally, the terminal device may obtain the first timer length of the uplink drx-HARQ-RRT timer through the following two possible implementation manners:

one possible implementation:

the terminal equipment receives RRC configuration information sent by the network equipment, and determines the timer length of an uplink drx-HARQ-RRT timer included in the RRC configuration information as the first timer length.

Optionally, the RRC configuration information may include other parameters, for example, a DRX cycle, a DRX duration timer, a DRX inactivity timer, an uplink DRX-HARQ-RTT timer, a downlink DRX-HARQ-RTT timer, an uplink retransmission timer, and a downlink retransmission timer.

In this possible implementation, it can also be understood that: the first timer length is a fraction of the first information. The terminal device receives a portion (first timer length) of the first information from the network device.

Another possible implementation:

the terminal equipment acquires the motion information of the terminal equipment and the motion information of the network equipment, and determines the first timer length of the uplink drx-HARQ-RRT timer according to the motion information of the terminal equipment and the motion information of the network equipment. This process may be referred to as the process of determining the first information in S301, and is not described herein again.

Alternatively, if the terminal device acquires the motion information of the network device in S1001, in S1003, the terminal device may directly use the motion information of the network device acquired in S1001, or the terminal device may acquire the motion information of the network device again.

S1004, the terminal equipment determines first information corresponding to an uplink drx-HARQ-RRT timer of the terminal equipment according to the motion information of the terminal equipment and the motion information of the network equipment.

The first information comprises first adjustment information, and the first adjustment information comprises a first adjustment period and a first adjustment step length.

Optionally, after the terminal device determines to obtain the first information, the terminal device may further send the first information to the network device, for example, the terminal device may send the first information to the network device through RRC signaling or MAC CE.

It should be noted that the process of executing S1003 may refer to the process of determining the first information described in S301, and is not described herein again.

S1006, the terminal device performs DRX operation according to the uplink DRX-HARQ-RRT timer.

It should be noted that the execution process of S1004-S1006 may refer to the process of S604-S606, and will not be described herein again.

It should be noted that, when the first information includes the first start time offset, the process of the terminal device adjusting the timer length of the uplink drx-HARQ-RRT timer is similar to the embodiment shown in fig. 10, and is not described herein again.

It should be further noted that, for the downlink drx-HARQ-RTT timer, a process of the terminal device adjusting the timer length of the uplink drx-HARQ-RRT timer is similar to the communication process shown in fig. 8, and is not described herein again.

In the embodiment shown in fig. 10, the terminal device determines that the uplink drx-HARQ-RRT timer corresponds to the first information according to the motion information of the terminal device and the motion information of the network device, and adjusts the timer length of the uplink drx-HARQ-RRT timer according to the first information. The first information is related to the motion information of the terminal device and the network device, so that the terminal device can accurately adjust the timer length of the uplink drx-HARQ-RRT timer of the terminal device according to the first information. In the above process, the terminal device and the network device perform less interaction to obtain the first information, so that the signaling overhead is relatively low.

Next, with reference to fig. 11, a detailed description will be given of a communication method shown in the embodiment of fig. 10 by way of a specific example. Fig. 11 is a schematic diagram of a communication process according to an embodiment of the present application.

after the network device and the terminal device establish RRC connection, the network device sends RRC configuration information to the terminal device at time t0, where the RRC configuration information includes an uplink drx-HARQ-RRT timer (or a timer length of the uplink drx-HARQ-RRT timer), and the terminal device may determine the timer length of the uplink drx-HARQ-RRT timer as a first timer length of the uplink drx-HARQ-RRT timer and adjust the timer length of the uplink drx-HARQ-RRT timer to the first timer length.

And the terminal equipment determines first information corresponding to an uplink drx-HARQ-RRT timer of the terminal equipment at the time T2 according to the motion information of the terminal equipment and the motion information of the network equipment, wherein the first information comprises a first adjustment period T1 and a first adjustment step length d 1. At time T3 after the elapse of time T1 from time T1, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+ d1, that is, adds d1 to the current timer length L1. At time T7 after the lapse of time duration T1 from time T3, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1, that is, adds d1 to the current timer length L1+ d 1.

Assume that the terminal device determines to obtain new first information at time T9, where the new first information includes a first adjustment period T2 and a first adjustment step d 2. At time T12 after the elapse of time T2 from time T7, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1+ d2, that is, adds d2 to the current timer length L1+2 × d 1. At time T16 after the lapse of time duration T2 from time T12, the terminal apparatus sets the timer length L of the uplink drx-HARQ-RRT timer to L1+2 × d1+2 × d2, that is, adds d2 to the current timer length L1+2 × d1+ d 2. And so on.

Referring to the DRX procedure in fig. 11, the procedure of the terminal device performing DRX operation according to the DRX-HARQ-RRT timer is as follows:
