And once there is a message loss or false reception, a survivinal time timer is started. If a message arrives and is correctly received within the survival time, the receiving end system keeps the original state (working state); otherwise, once the survival time timer expires, the receiving end system is turned off urgently and enters a down state. After entering the downtime state, the receiving end system can take certain measures to restore the system or keep the downtime state all the time.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.
Referring to fig. 2, fig. 2 is a flowchart of a PDCP duplication processing method according to an embodiment of the present invention, where the method is applied to a communication device as a receiving end, and includes the following steps:
step 11: the communication equipment acquires the times and/or total duration of the communication equipment in the downtime state within a preset duration;
step 12: and the communication equipment determines whether the PDCP duplication is required to be activated or reconfigured according to the acquired times and/or the total duration and the corresponding judgment threshold.
According to the embodiment of the invention, the PDCP duplication is activated or reconfigured, so that the reliability of transmission can be improved, the transmission delay is reduced, and the system stability is improved. In addition, by setting a reasonable judgment threshold, the resource waste can be reduced. Can be applied to IIoT scenes.
It should be noted that the communication device may be a network side device or a terminal. In the case of DC (Dual Connectivity ), the network side device may activate PDCP duplication or reconfigure PDCP duplication by itself, the terminal may request activation of PDCP duplication or reconfigure PDCP duplication by sending an indication to the network side device, and in the case where the network side device pre-configures the terminal with resources, the terminal may also activate PDCP duplication or reconfigure PDCP duplication by itself.
The processing method of PDCP duplication described above is exemplified below.
In some optional embodiments, if it is determined that PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured in the case that the communication device is a terminal, the step of determining whether PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured according to the acquired times and/or the total duration and the corresponding judgment threshold further includes:
acquiring the size relation between the survival time and the loop-back time;
and if the survival time length is longer than the loop-back time length, sending indication information for requesting activation of PDCP duplication or indication information for requesting reconfiguration of PDCP duplication to network side equipment.
In other optional embodiments, if it is determined that PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured in the case that the communication device is a terminal, the step of determining whether PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured according to the acquired times and/or the total duration and the corresponding judgment threshold further includes:
acquiring the size relation between the survival time length and the loop-back time length of the system;
and if the survival time is not longer than the loop-back time, independently activating PDCP duplication or reconfiguring PDCP duplication.
It should be noted that, the survival time is a new parameter related to the validity of the system, and referring to fig. 1, it can be understood that a system enters a recovery time before entering an "unavailable" state (i.e. a down state) due to a (or a plurality of) message loss/transmission errors. For periodic traffic, the duration of survival is a period of time, which can also be understood as the maximum number of consecutive error/lost messages. The loop time length, namely cycle time, refers to the time length required from the sending end controller to the sending end receiving feedback, and comprises a bottom layer processing time delay and an air interface transmission time delay. Alternatively, the cycle Time may refer to the Time taken to transmit a packet (the Time taken for the sender to send and receive feedback from the receiver), that is, may be considered as an RTT (Round Trip Time). For some severe IIoT scenarios, the survival duration is equal to 1 loop-back duration.
Optionally, the judgment threshold comprises at least one of a frequency threshold, a total duration threshold and a total duration ratio threshold;
in the case that only the number of times is acquired, the step of determining whether the PDCP duplication needs to be activated or reconfigured includes:
Comparing the times with the times threshold; if the number of times is greater than or equal to the number of times threshold, determining that PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured;
in the case that only the total duration is acquired, the step of determining whether the PDCP duplication needs to be activated or reconfigured includes:
comparing the total duration with the total duration threshold; if the total time length is greater than or equal to the total time length threshold, determining that PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured; or alternatively, the process may be performed,
acquiring the ratio of the total duration to the preset duration; comparing the ratio with the total duration ratio threshold; if the ratio is greater than or equal to the total duration ratio threshold, determining that PDCP duplication needs to be activated or PDCP duplication needs to be reconfigured;
in the case of obtaining the number of times and the total duration, the step of determining whether the PDCP duplication needs to be activated or reconfigured includes:
comparing the times with the times threshold, and comparing the total duration with the total duration threshold; and if the times are greater than or equal to the times threshold and the total time length is greater than or equal to the total time length threshold, determining that the PDCP duplication needs to be activated or the PDCP duplication needs to be reconfigured.
In addition, in the case of acquiring the number of times and the total duration, the step of determining whether the PDCP duplication needs to be activated or reconfigured may also include:
acquiring the ratio of the total duration to the preset duration;
comparing the times with the times threshold, and comparing the ratio with the total duration ratio threshold;
and if the times are greater than or equal to the times threshold and the ratio is greater than or equal to the total duration ratio threshold, determining that the PDCP duplication needs to be activated or the PDCP duplication needs to be reconfigured.
Optionally, before the step of determining whether to activate PDCP duplication or reconfigure PDCP duplication according to the acquired times and/or the total duration and the corresponding judgment threshold if the communication device is a terminal, the method further includes:
and receiving configuration information sent by network side equipment, wherein the configuration information comprises at least one of the preset duration, the frequency threshold, the total duration threshold and the total duration ratio threshold.
In addition, the configuration information may further include the survival time period.
Optionally, the configuration information is sent by a broadcast message and/or dedicated signaling.
Optionally, before the step of obtaining the number of times and/or the total duration of the downtime state of the communication device in the preset duration, the method further includes:
if the higher layer receives an out of sync indication sent by the bottom layer, starting the survival time period timing; if the high layer does not receive the in sync indication sent by the bottom layer within the survival time, entering a downtime state; or alternatively, the process may be performed,
if the higher layer receives the beam failure instance indication of the bottom layer (beam failure instance indication), the survival duration timer is started; if the beamfailuredetection timer, the beamFailureInstanceMaxCount (maximum count of beam failure instance), or other reference signals for indicating beam failure detection (beam failure detection) are not reset by a higher layer within the survival time, entering a downtime state; or alternatively, the process may be performed,
if the higher layer receives NACK (negative determination), starting the survival time; and if the high layer does not receive ACK (positive acknowledgement) within the survival time, entering a downtime state.
That is, the communication device entering the downtime state may be due to a link occurrence radio link failure (radio link failure). When the continuous packet loss starts, the bottom layer sends out of sync indication to the high layer, the timing of the survival time is triggered to be started, if the high layer receives in sync indication sent by the bottom layer within the survival time, the communication device does not enter a downtime state, and otherwise, the communication device enters the downtime state.
The communication device entering the downtime state may also be due to the occurrence of a beam failure. When the continuous packet loss starts, the communication device receives beam failure instance indication of the bottom layer by the upper layer, triggers to start the timing of the survival time, and does not enter the downtime state if beamFailureDetectionTimer, beamFailureInstanceMaxCount or other reference signals for indicating beam failure detection (beam failure detection) are reset by the upper layer (if beamFailureDetectionTimer, beamFailureInstanceMaxCount, or any of the reference signals used for beam failure detection is reconfigured by upper layers) within the survival time, or enters the downtime state otherwise.
In the embodiment of the present invention, the higher layer may specifically be a MAC (Media Access Control ) layer, and the lower layer may specifically be a physical layer.
The second embodiment of the invention provides a PDCP duplication processing method, which is applied to a terminal, and specifically comprises the following steps:
21. the terminal receives the survival time, the preset time and the time threshold configured by the network side equipment through broadcasting or special signaling.
22. Starting from receiving a first packet of the network side equipment, the terminal starts a first timer for counting the preset duration and a counter for counting the times of the terminal in the downtime state.
23. The terminal generates continuous packet loss in the downlink transmission process of the receiving network side equipment, so that the MAC layer always receives NACK feedback. When the MAC layer receives the first NACK feedback, the terminal starts a survival time length timer, if the MAC layer receives the ACK feedback before the survival time length timer is overtime, the survival time length timer is cleared, otherwise, once the survival time length timer is overtime (namely, enters a downtime state), the counter is increased by 1. The terminal takes certain actions such as radio link control (RLC: radio Link Control) re-establishment, etc., to ensure transmission.
24. When the counted number of times of the counter reaches the threshold number of times, the terminal transmits indication information for requesting activation of PDCP copying to the network side equipment, and the network side equipment configures the terminal to perform PDCP copying. And resetting the first timer and the counter.
25. If the first timer is overtime, namely the number of times counted by the counter in the preset time period does not reach the number threshold, the first timer and the counter are cleared.
In the embodiment of the invention, the terminal is in the dual-connection state, and only the PDCP copies the inactive state, so that the process of adding auxiliary nodes and the like is not involved once the terminal needs to be activated.
The third embodiment of the invention provides a PDCP duplication processing method, which is applied to a terminal, and specifically comprises the following steps:
31. the terminal receives a survival time length, a preset time length and a total time length threshold which are configured by network side equipment through a broadcast or special signaling mode, wherein the survival time length is equal to a loop-back time length. In addition, the network side device configures PDCP duplication of two links (leg (s)) to the terminal.
32. Starting from receiving a first packet, the terminal starts a first timer for counting the preset duration and a second timer for counting the total duration of the terminal in the downtime state.
33. The terminal generates continuous packet loss in the downlink transmission process of the receiving network side equipment, so that the MAC layer always receives NACK feedback. When the MAC layer receives the first NACK feedback, the terminal starts a survival time length timer, if the MAC layer receives the ACK feedback before the survival time length timer is overtime, the survival time length timer is cleared, otherwise, once the survival time length timer is overtime (namely enters a downtime state), the second timer starts to count until the terminal reenters a working state to stop counting. When the survival duration timer is overtime next time, the second timer starts to count on the basis of the last time, namely, the duration in the downtime state is counted in an accumulated mode each time.
34. When the total duration counted by the second timer reaches the total duration threshold, the terminal automatically reconfigures PDCP duplication, for example, four links of PDCP duplication are added. And resetting the first timer and the second timer.
35. If the first timer is overtime, that is, the total time counted by the second timer in the preset time does not reach the total time threshold, the first timer and the second timer are cleared.
The fourth embodiment of the invention provides a PDCP duplication processing method, which is applied to a terminal, and specifically comprises the following steps:
41. the terminal receives a survival time length, a preset time length and a total time length ratio threshold which are configured by the network side equipment in a broadcast or special signaling mode, wherein the survival time length is equal to five loop-back time lengths.
42. Starting from receiving a first packet, the terminal starts a first timer for counting the preset duration and a second timer for counting the total duration of the terminal in the downtime state.
43. And when the terminal receives the downlink transmission process of the network side equipment, the higher layer receives the out-of-step indication sent by the bottom layer and triggers to start the survival time length timer, if the higher layer receives the synchronous indication sent by the bottom layer before the survival time length timer is overtime, the survival time length timer is cleared, otherwise, once the survival time length timer is overtime (namely enters into a downtime state), the second timer starts to count until the terminal reenters into a working state and stops counting. After the survival duration timer is overtime next time, the second timer starts to count on the basis of the last time, namely, the duration in the downtime state is counted in an accumulated mode each time.
44. When the ratio of the total time counted by the second timer to the preset time reaches the total time ratio threshold, the terminal sends indication information for requesting to reconfigure PDCP duplication to the network side equipment, and the network side equipment reconfigures four PDCP duplication links.
