Description

User equipment, network equipment communication method, equipment and system

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a device, and a system for communication between a user equipment and a network device.

Background

In Non-Terrestrial communication Network (NTN) technology under study by the existing 3rd Generation Partnership Project (3 GPP), the NTN generally provides communication services to Terrestrial users by means of satellite communication. Compared with the ground cellular network communication, the satellite communication is not limited by user regions and has greater social value, namely, the satellite communication can be covered in remote mountain areas and poor and lagged countries or areas with lower cost, so that people in the areas can enjoy advanced voice communication and mobile internet technologies, the digital gap between the areas and developed areas is favorably reduced, and the development of the areas is promoted; the satellite communication distance is long, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Among them, communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Orbit (LEO) satellites, High-elliptic Orbit (HEO) satellites, and the like according to the difference in orbital height. The main studies at the present stage are LEO and GEO.

In 5G communication (New Radio, NR for short), in an existing mechanism, if a transmission time timer (drx-HARQ-RTT-TimerDL) corresponding to a certain hybrid automatic repeat request (HARQ) of a terminal is overtime and downlink data transmitted by using the HARQ process is unsuccessfully decoded, the terminal starts a retransmission timer (drx-retransmission TimerDL) corresponding to the HARQ process.

If the network sets the HARQ feedback functions of all HARQ processes of a User Equipment (UE) to an on state, and the number of uplink/downlink transmission opportunities that can be obtained by the UE within Round Trip Time (RTT) of signal transmission between the network and the UE is greater than the number of uplink/downlink HARQ processes available to the UE, uplink/downlink HARQ process blocking occurs, that is, all uplink/downlink HARQ processes of the UE are used and are in the period of operation of the RTT timer, and at this Time, the network does not have an available HARQ process even if it is expected to schedule uplink/downlink transmission of the UE.

When the RTT timer corresponding to the first used HARQ process times out, for uplink HARQ, the UE starts a discontinuous reception uplink retransmission timer corresponding to the uplink HARQ process, so that the UE can enter a discontinuous reception Active Time (DRX Active Time), and thus the UE can monitor a Physical Downlink Control Channel (PDCCH for short) scheduled by a network. For downlink HARQ, the UE starts the discontinuous reception downlink retransmission timer corresponding to the downlink HARQ process only when the UE feeds back non-acknowledgement (NACK) to the downlink HARQ process, and the UE does not start the discontinuous reception downlink retransmission timer corresponding to the downlink HARQ process if the UE feeds back Acknowledgement (ACK) to the downlink HARQ process. Thus, even if the network desires to schedule downlink transmission for the UE and the UE also has available downlink HARQ processes, the UE needs to wait until the UE starts an activation timer (DRX-onDurationTimer) at the next DRX cycle before scheduling the UE. Especially if the HARQ is blocked for a Long time, the UE may switch to a Long discontinuous reception cycle (Long DRX cycle) due to timeout of a short cycle timer (DRX-short timer) caused by not scheduling for a Long time. Thus, the UE needs to wait longer to start DRX-onduration timer (the duration of UE wake-up at the beginning of one DRX Cycle) into DRX Active Time.

In view of the above problem that in the case of process congestion of hybrid automatic repeat request HARQ, in the prior art, after recovering from the case of process congestion of hybrid automatic repeat request HARQ to an available HARQ process, the ue needs to wait for a long time before restarting the drx persistent timer to monitor the PDCCH indicating scheduling, which results in an excessively long downlink scheduling delay, an effective solution has not been proposed at present.

Example 1

In accordance with an embodiment of the present invention, there is provided a flowchart embodiment of a method for user equipment communication, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

Fig. 1 is a flowchart illustrating a method for user equipment to communicate according to a first embodiment of the present invention, as shown in fig. 1, on a user equipment side, the method includes the following steps:

step S102, user equipment receives an instruction sent by network equipment;

in an optional implementation, in a communication process of a user equipment, the user equipment receives an instruction sent by a network device, where the instruction is used to instruct the user equipment to enter a state of monitoring a Physical Downlink Control Channel (PDCCH) when a transmission time timer corresponding to a specified process of a Downlink hybrid automatic repeat request expires under a condition that the process of the Downlink hybrid automatic repeat request is blocked;

the user equipment can be terminal equipment with a wireless communication function, such as a smart phone (for example, a mobile phone using an Android system or a mobile phone using an IOS system), a tablet computer, and intelligent wearable equipment (for example, Augmented Reality (AR) equipment, Virtual Reality (VR) equipment or a smart watch); the network device may be a server for supporting communication services.

And step S104, under the condition that the process of the downlink hybrid automatic repeat request is determined to be blocked and the transmission time timer corresponding to the specified downlink hybrid automatic repeat request is determined to be overtime, the user equipment monitors the physical downlink control channel according to the indication signaling.

In an optional implementation scheme, based on an instruction received by the user equipment in step S102 and sent by the network equipment, when the user equipment detects that a transmission Time timer (DRX-HARQ-RTT-TimerDL) corresponding to a specified downlink Hybrid Automatic Repeat Request (HARQ) is expired, the user equipment enters discontinuous reception Active Time (DRX Active Time) according to the instruction and monitors the PDCCH when the downlink Hybrid Automatic Repeat Request is blocked, so that a problem that the downlink scheduling delay is too long due to a long wait for the user equipment to recover from the situation that the downlink HARQ process is blocked to the process that an available HARQ process occurs in the prior art is avoided.

The method for UE communication provided in this embodiment of the present application may be applied to a Non-Terrestrial communication Network (NTN) system, where when HARQ feedback functions of all Downlink HARQ processes of a UE are in an on state, and when a Downlink HARQ process congestion occurs in the UE (that is, when a transmission Time timer (DRX-HARQ-RTT-TimerDL) corresponding to all Downlink HARQ processes is in an operating state and no idle Downlink HARQ process is available for Downlink transmission), the Network device instructs the UE (User Equipment, UE for short) to immediately or soon enter a discontinuous reception Active Time (DRX Active Time) after a transmission Time timer (DRX-HARQ-RTT-TimerDL) corresponding to a first Downlink HARQ times out, so that the UE can monitor a Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviated PDCCH) to reduce service delay.

In an alternative implementation, the method for user equipment communication provided in the embodiment of the present application is as follows:

in the process of implementing the method for user equipment communication provided by the embodiment of the present application, the method can be implemented by three implementation manners, where the three implementation manners include:

the first method is as follows: the network equipment indicates the UE to enter DRX Active Time after the transmission Time timer corresponding to the first downlink HARQ is overtime;

the second method comprises the following steps: the network equipment indicates the UE to start a first timer after the transmission Time timer corresponding to the first downlink HARQ is overtime, and the UE is in DRX Active Time during the running period of the first timer;

the third method comprises the following steps: and the network equipment indicates the UE to switch to a short discontinuous reception cycle (short DRX cycle) after the transmission time timer corresponding to the first downlink HARQ is overtime.

Through the three implementation modes, the UE can immediately or as soon as possible enter the DRX Active Time when recovering from the state of downlink HARQ blockage, so that the UE can monitor the PDCCH and reduce the service delay.

In an optional implementation, before receiving an instruction sent by the network device, the user equipment further receives Radio Resource Control (Radio Resource Control, RRC for short) configuration information sent by the network device, and based on the three implementation manners, the RRC corresponding to the three implementation manners in the received RRC are different, which is specifically as follows:

in the first mode: the RRC message includes: communication parameters of discontinuous reception (related parameters configuring DRX) and configuration parameters of a process of a downlink hybrid automatic repeat request (configuration parameters of a process of downlink HARQ), wherein,

the configuration parameters of the downlink HARQ process comprise: long Discontinuous Reception cycle (Long DRX cycle), active timer (DRX-onDurationTimer), inactive timer (DRX-inactivity timer), transmission time timer (DRX-HARQ-RTT-TimerDL), and retransmission timer (DRX-retransmission TimerDL), where DRX is Discontinuous Reception, i.e., Discontinuous Reception.

The configuration parameters of the downlink HARQ process comprise: and the number of the downlink HARQ processes is equal to the number of the downlink HARQ processes, and the HARQ feedback functions of all the downlink HARQ processes are configured to be in an open state.

In the second mode: the RRC message includes: communication parameters of discontinuous reception (related parameters for configuring DRX), configuration parameters of a process of a downlink hybrid automatic repeat request (configuration parameters of a process of downlink HARQ), and a first timer, wherein,

the configuration parameters of the downlink HARQ process comprise: long DRX cycle, DRX-onDurationTimer, DRX-inactivytytimeter, DRX-HARQ-RTT-TimerDL, DRX-retransmission TimerDL.

The configuration parameters of the downlink HARQ process comprise: the number of the downlink HARQ processes is determined, and the HARQ feedback functions of all the downlink HARQ processes are configured to be in an open state;

configuring a first timer, the first timer being included in the DRX configuration.

In the third mode: the RRC message includes: long DRX cycle, Short discontinuous reception cycle (Short DRX cycle), Short cycle timer (DRX-ShortCycleTimer), DRX-onDurationTimer, DRX-InactivityTimer, DRX-HARQ-RTT-TimerDL, DRX-retransmission TimerDL, etc.;

Based on the RRC information of the three implementation manners, when the transmission time timer of the process of the downlink hybrid automatic repeat request is expired, the ue enters the discontinuous reception activation time according to the instruction when the transmission time timer of the process of the downlink hybrid automatic repeat request is stopped, and the monitoring on the physical downlink control channel is specifically as follows:

in the first mode, after the network device indicates that the UE times out the transmission Time timer corresponding to the first downlink HARQ process, the UE enters DRX Active Time as follows:

optionally, when it is determined that a process of a downlink hybrid automatic repeat request is blocked and it is determined that a transmission time timer corresponding to a specified downlink hybrid automatic repeat request is overtime, the monitoring, by the user equipment, of the physical downlink control channel according to the indication signaling includes:

step1, under the condition that it is determined that the process of the downlink hybrid automatic repeat request is blocked and that the transmission time timer corresponding to the specified downlink hybrid automatic repeat request after the process of the downlink hybrid automatic repeat request is blocked is overtime, the user equipment enters the discontinuous reception activation time according to the indication signaling to monitor the physical downlink control channel.

In an optional implementation, as shown in fig. 2, fig. 2 is a schematic diagram of controlling, by a user equipment, the user equipment when a downlink HARQ process is blocked in a method for user equipment communication according to an embodiment of the present invention, where in a case that the downlink HARQ process is blocked (that is, "downlink HARQ process blocking" in this embodiment), if a network device expects to be able to schedule a UE as early as possible after there is a usable downlink HARQ process, the network device may instruct the UE to enter DRX Active Time immediately after a transmission Time timer corresponding to a 1 st downlink HARQ expires.

For the UE whose HARQ feedback functions of all downlink HARQ processes are in an on state, the network device indicates, through the instruction, that the UE enters discontinuous reception Active Time (DRX Active Time) after a transmission Time timer (DRX-HARQ-RTT-TimerDL) corresponding to a certain downlink HARQ (i.e., in this embodiment, the first downlink HARQ) is overtime, that is, the UE monitors the PDCCH.

The UE receives an instruction of the network equipment, and the instruction instructs the UE to enter DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ.

The instruction may be a downlink MAC Control Element (MC Control Element, MAC CE for short), or a PDCCH instructing downlink or uplink scheduling.

The indication instruction specifies that the indication instruction is effective only once, namely after the UE receives the indication instruction, the DRX Active Time is entered when the first Time timeout occurs for DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ.

The embodiment of the application provides two service scenes:

a first service scenario: for a Physical Downlink Shared Channel (PDSCH) transmission of a dynamic scheduling indication:

step 1: when the UE receives the PDCCH indicating that a certain downlink HARQ process is used for PDSCH transmission, the UE stops a retransmission timer (drx-retransmission timer dl) corresponding to the downlink HARQ process.

Step 2: and the UE starts a transmission time timer (drx-HARQ-RTT-TimerDL) corresponding to the downlink HARQ process after finishing the transmission of the ACK/NCAK feedback aiming at the downlink transmission.

And step 3: and if the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime and the UE feeds back NACK for the downlink transmission, the UE starts the drx-retransmission TimerDL corresponding to the downlink HARQ process.

And 4, step 4: and if the network equipment indicates that the UE enters DRX Active Time after the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE enters DRX Active Time after the DRX-HARQ-RTT-TimeDL corresponding to the downlink HARQ process is overtime.

Service scene two: for PDSCH transmissions that occur on the configured downlink grant:

step 1: when the UE receives a MAC PDU (MAC Protocol Data unit, Protocol Data unit of the MAC layer) on the configured downlink grant resource, the UE stops drx-retransmission timerdl corresponding to the downlink HARQ process.

Step 2: and the UE starts drx-HARQ-RTT-TimeDL corresponding to the downlink HARQ process after finishing the transmission of the ACK/NCAK feedback aiming at the downlink transmission.

And 4, step 4: and if the network indicates that the UE enters DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process and the current downlink HARQ process is the first downlink HARQ process, the UE enters DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the downlink HARQ process.

In an alternative embodiment, as shown in fig. 2, the process is embodied in a first mode by combining the above examples of the present application, and the following examples are taken as examples to illustrate:

the UE receives the following network RRC configuration information:

(1) configuring relevant parameters of DRX, including Long DRX cycle, DRX-onDuration timer, DRX-Inactivitytimer, DRX-HARQ-RTT-TimerDL, DRX-retransmission TimerDL and the like;

(2) configuring 4 downlink HARQ processes for the UE, wherein HARQ feedback functions of the 4 downlink HARQ processes are all in an open state;

and 2, the UE receives PDSCH transmissions indicated by 4 PDCCHs in sequence, the 4 PDSCH transmissions respectively use HARQ ID 0, HARQ ID 1, HARQ ID 2 and HARQ ID 3, the UE receives the PDSCH on the resource indicated by each PDCCH, and the UE starts drx-HARQ-RTT-TimerDL corresponding to the HARQ ID after finishing ACK feedback aiming at the PDSCH.

3. The network equipment indicates the UE to enter DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 in 4 PDCCHs sent to the UE.

4. Since the UE feeds back ACK for the 4 PDSCH transmissions, the UE does not start drx-retransmission TimerDL corresponding to each HARQ ID after the drx-HARQ-RTT-TimerDL corresponding to the HARQ ID expires.

And 5, the UE starts to enter DRX Active Time after the DRX-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 is overtime according to the indication of the network equipment, namely the UE monitors the PDCCH.

In the second mode, after the network device indicates the UE that the transmission Time timer corresponding to the first downlink HARQ process is expired, the UE starts the first timer, and the UE is in DRX Active Time during the operation of the first timer specifically as follows:

step1, when determining that the process of the downlink hybrid automatic repeat request is blocked and determining that the transmission time timer corresponding to the specified downlink hybrid automatic repeat request after the process of the downlink hybrid automatic repeat request is blocked is overtime, the user equipment starts a first timer according to the instruction, enters the discontinuous reception activation time during the running period of the first timer, and monitors the state of the physical downlink control channel in the first timer.

In an optional implementation, as shown in fig. 3, fig. 3 is another schematic diagram of a user equipment controlling when a downlink HARQ process is blocked in a user equipment communication method according to an embodiment of the present invention, where in a case that the downlink HARQ process is blocked (that is, "downlink hybrid automatic repeat request process blocking" in this embodiment), if a network device expects to be able to schedule a UE as early as possible after there is a usable downlink HARQ process, the UE may be instructed to start a first timer immediately after a transmission Time timer corresponding to a 1 st downlink HARQ expires, and the UE is in discontinuous reception Active Time (DRX Active Time) during operation of the first timer.

For the UE whose HARQ feedback functions of all downlink HARQ processes are in an on state, the network device instructs, through an instruction, the UE to start a first timer after a transmission Time timer (DRX-HARQ-RTT-TimerDL) corresponding to a certain downlink HARQ process (i.e., in this embodiment, a first downlink HARQ process) is expired, and the UE is in DRX Active Time during the operation of the first timer, and monitors the PDCCH.

The UE receives an instruction of the network equipment, and the instruction instructs the UE to start a first timer after the time-out of drx-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

The indication instruction specifies that the first timer is effective only once, that is, when the first time that the drx-HARQ-RTT-TimerDL corresponding to the first downlink HARQ times out after the UE receives the indication instruction, the first timer is started.

The embodiment of the application provides two service scenes:

And 4, step 4: and if the network equipment indicates that the UE starts the first timer after the drx-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE starts the first timer after the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime.

step 1: when the UE receives one MAC PDU (Protocol Data unit of physical MAC layer) on the configured downlink grant resource, the UE stops drx-retransmission timerdl corresponding to the downlink HARQ process.

And 4, step 4: and if the network indicates that the UE starts the first timer after the drx-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE starts the first timer after the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime.

The UE is in DRX Active Time during the first timer running period, that is, the UE monitors the PDCCH during the first timer running period.

In an alternative embodiment, as shown in fig. 3, the following example is taken as an example to illustrate the process implemented in the second embodiment in combination with the above examples of the present application:

the UE receives the following network RRC configuration information:

(1) configuring relevant parameters of DRX, including Long DRX cycle, DRX-onDuration timer, DRX-Inactivitytimer, DRX-HARQ-RTT-TimerDL, DRX-retransmission TimerDL and the like, and a first timer;

3. The network equipment indicates the UE to start a first timer after the time-out of drx-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 in 4 PDCCHs sent to the UE.

And 5, the UE starts a first timer after the drx-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 is overtime according to the indication of the network equipment, and monitors the PDCCH during the running period of the first timer.

The third method comprises the following steps: the network device instructs the UE to switch to a short discontinuous reception cycle (short DRX cycle) after the transmission time timer corresponding to the first downlink HARQ process expires, as follows:

optionally, when determining that the process of the downlink hybrid automatic repeat request is blocked and determining that the transmission time timer corresponding to the specified downlink hybrid automatic repeat request is overtime, the ue monitors the physical downlink control channel according to the indication signaling, including:

step1, under the condition that it is determined that the process of the downlink hybrid automatic repeat request is blocked and that the transmission time timer corresponding to the designated downlink hybrid automatic repeat request after the process of the downlink hybrid automatic repeat request is blocked is overtime, the user equipment enters a short-term discontinuous reception period according to the instruction, so that the user equipment enters discontinuous reception activation time within the preset time and monitors the state of the physical downlink control channel within the discontinuous reception activation time.

In an optional embodiment, as shown in fig. 4, fig. 4 is a schematic diagram of a user equipment controlling when a downlink HARQ process is blocked in a user equipment communication method according to an embodiment of the present invention, and when the downlink HARQ process is blocked (that is, "downlink hybrid automatic repeat request process blocking" in this embodiment), if a network device expects to schedule a UE as early as possible after there is a usable downlink HARQ process, the network device may instruct the UE to switch to a short discontinuous reception cycle (short DRX cycle) after a transmission Time timer corresponding to the 1 st downlink HARQ times out, so that the UE may start DRX-on duration to enter DRX Active Time as early as possible.

For the UE whose HARQ feedback functions of all downlink HARQ processes are in an on state, the network device instructs, through an instruction, the UE to switch to a short DRX cycle after a transmission time timer (DRX-HARQ-RTT-TimerDL) corresponding to a certain downlink HARQ process (i.e., a first downlink HARQ process in this embodiment) is expired.

The UE receives an instruction of the network equipment, and the instruction instructs the UE to switch to a short DRX cycle after expiration of DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process.

The indication instruction specifies that the indication instruction is effective only once, namely after the UE receives the indication instruction, the UE is switched to a short DRX cycle when the first time expiration occurs in a DRX-HARQ-RTT-TimerDL corresponding to a first downlink HARQ process.

The embodiment of the application provides two service scenes:

And 4, step 4: and if the network equipment indicates that the UE starts the first timer after the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE is switched to the short DRX cycle after the DRX-HARQ-RTT-TimeDL corresponding to the downlink HARQ process is overtime.

And 4, step 4: and if the network indicates that the UE starts the first timer after the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE is switched to the short DRX cycle after the DRX-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime.

In an alternative embodiment, as shown in fig. 4, the process is specifically implemented in the third embodiment in combination with the above examples of the present application, and the following example is taken as an example for explanation:

the UE receives the following network RRC configuration information:

(1) configuring relevant parameters of DRX, including Long DRX cycle, Short DRX cycle, DRX-ShortCycleTimer, DRX-onDurationtimer, DRX-Inactivitytimer, DRX-HARQ-RTT-TimerDL, DRX-RecransmissionTimeDL and the like;

3. Since the UE feeds back ACK for the 4 PDSCH transmissions, the UE does not start drx-retransmission TimerDL corresponding to each HARQ ID after the drx-HARQ-RTT-TimerDL corresponding to the HARQ ID expires.

4. And the network equipment indicates the UE to switch to the short DRX cycle after the expiration of DRX-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 in the 4 PDCCHs sent to the UE.

And 5, the UE starts or restarts a DRX-ShortCycleTimer each time the PDCCH is received, and the UE is switched from a short DRX cycle to a long DRX cycle after the DRX-ShortCycleTimer is overtime.

And 6, the UE switches from the Long DRX cycle to the short DRX cycle after the DRX-HARQ-RTT-TimerDL corresponding to the HARQ ID 0 is overtime according to the indication of the network.

In the case that the user equipment blocks the process of the downlink hybrid automatic repeat request in the embodiment of the present application, after the transmission time timer corresponding to the process of the designated downlink hybrid automatic repeat request is overtime, the state of entering the monitoring physical downlink control channel according to the instruction can be realized by any one of the first mode to the third mode, in the second embodiment, a first timer is set in the first embodiment, monitoring a physical downlink control channel during the operation period of a first timer so that the UE is not in DRX Active Time for a long Time, but releases the DRX Active Time after the first timer is timed out, in terms of power consumption of the user equipment, the user equipment stops monitoring the PDCCH after the first timer finishes timing, so that the power consumption of the user equipment is reduced, and the technical effect of power saving is achieved. Similarly, in the technical scheme of the third mode, it is avoided that in the prior art, after the situation that the process of the hybrid automatic repeat request HARQ is blocked is recovered to the situation that an available HARQ process exists, the ue needs to wait for a long time to restart the drx continuous timer so as to monitor the PDCCH indicating scheduling, but the transmission time timer corresponding to the first dl HARQ process is overtime, and the ue enters a short drx cycle according to the indication instruction.

It should be noted that, the method for user equipment communication provided in the embodiment of the present application is only described by taking the above example as an example, and is not particularly limited by the method for implementing user equipment communication provided in the embodiment of the present application.
