Description

Transmission processing method, transmission processing device, communication equipment and readable storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a transmission processing method, a transmission processing device, communication equipment and a readable storage medium.

Background

To support the time-to-live feature, the terminal may be configured with a data copy function. When the terminal triggers the survival time (for example, the survival time is triggered due to failure of data transmission), a plurality of transmission paths can be used for copying and transmitting the subsequent data, so that the reliability of the data transmission is ensured.

However, in the dual connection (Dual Connectivity, DC) scenario, since a certain network node cannot know the survival time status of a terminal in real time, resources required for transmitting data through a transmission path managed by the network node cannot be provided in time. If the terminal selects the transmission path managed by the network node as the transmission path, at this time, the terminal cannot transmit the copy data through the transmission path due to lack of resources, which results in additional increase of data processing load of the terminal.

All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the terms "first" and "second" are generally intended to be used in a generic sense and not to limit the number of objects, for example, the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

It is noted that the techniques described in embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access, SC-FDMA), and other systems.

The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation，6G) A communication system.

In order to facilitate understanding of the embodiments of the present application, the following technical points are first described:

1. Brief introduction of Time to Survival (ST)

For a service with a time-to-live requirement, the receiving end has an expected arrival time of the data packet, and when the receiving end does not receive the data packet in the expected arrival time, the receiving end enters the time-to-live requirement. If the receiving end has not successfully received any data packet within the alive time, the communication service will enter an unavailable state (unavailable state), so that a longer time is required for the recovery process of the normal communication service. In short, for this type of service, a loss of a plurality of consecutive packets cannot occur, otherwise the communication at the receiving end will enter an unavailable state.

To meet the time-to-live requirement, it is necessary to ensure that no continuous N times of data transmission failure can occur, otherwise the receiving end application will enter a service unavailable state. In case of failure of consecutive M times of data transmission (M < N), the transmitting end triggers the survival time. In this state, the data transmitting end adopts a transmission strategy with high reliability to transmit data, so that the subsequent data packet can be expected to be successfully transmitted.

2. Packet data convergence protocol (Packet Data Convergence Protocol, PDCP) duplicate function (PDCP duplicate) profile

In the New Radio, the network may configure at least two transmission paths for the Radio bearer, where the transmission paths may correspond to only a single network node (e.g., carrier aggregation (Carrier Aggregation, CA) implementation) or may correspond to multiple different network nodes (e.g., DC implementation). The PDCP layer of the radio bearer can transmit one copy of data per transmission path when transmitting the data to improve data transmission reliability. The network side can activate/deactivate the data copy function of the radio bearer or activate/deactivate the transmission path of the radio bearer through MAC CE signaling. When the transmission path of the radio bearer corresponds to a plurality of network nodes, any network node may issue the above-mentioned media access Control (Medium Access Control, MAC) Control Element (CE). When issuing the MAC CE, no negotiation exists between the network nodes.

The wireless communication system includes a terminal 11, a network-side device 12, and a network-side device 13. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc..

The transmission processing method, the transmission processing device, the communication equipment and the readable storage medium provided by the embodiments of the application are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a transmission processing method, which is applied to a terminal, and includes:

step 201: and activating a second transmission path of the radio bearer by the terminal under the condition that the transmission of the first transmission path of the radio bearer fails, wherein the first transmission path and the second transmission path are transmission paths managed by the first network node.

It is understood that the first transmission path and the second transmission path may represent a type of transmission path, i.e., the number of transmission paths included in the first transmission path and the second transmission path is not limited.

It will be appreciated that in the event that the terminal fails to transmit data via the first transmission path, the first network node is aware of the failure of the data transmission by the terminal, since the first transmission path is managed by the first network node. It can be considered that the terminal will transmit subsequent data using the enhancement scheme, and thus the first network node can provide the resources required for transmitting data via the second transmission path managed by the first network node. And at the terminal side, the terminal correspondingly selects the second transmission path managed by the first network node to transmit data, thereby ensuring that the data can be always transmitted through the transmission path ensured by the resource. In addition, the resources required by the first network node to provide the second transmission path managed by the first network node for transmitting data may be that radio resources (such as Configured grant resources) reserved previously to the terminal are not reallocated to other terminals. The radio resources may also be provided to the terminal by dynamic scheduling.

Optionally, the radio bearer may be further configured with a fifth transmission path, the fifth transmission path being a transmission path managed by the second network node. In this case, the terminal always selects only the second transmission path managed by the first network node, and does not select the fifth transmission resource managed by the second network node, in the case where the transmission of the first transmission path fails. Since the first transmission path is not managed by the second network node, the second network node cannot or cannot timely learn the transmission state of the first transmission path. And further, it cannot be judged whether the terminal needs to transmit the subsequent data using the enhanced scheme, so that resources required for transmitting the data through the fifth transmission path cannot be provided in time. On the terminal side, the terminal can effectively avoid selecting a transmission path without resource guarantee to transmit data by not selecting the fifth transmission path, and avoid unnecessary data processing of a protocol entity (such as PDCP) of the terminal.

In addition, it should be noted that, in the case that the transmission of the first transmission path of the wireless terminal fails, the first network node managing the first transmission path may provide the resources required for transmitting data through the second transmission path in time, and the terminal correspondingly selects the second transmission path, so as to ensure that the terminal can always transmit data through the transmission path with resource guarantee. In the following examples, this will not be described in detail.

In one embodiment of the present application, the method further comprises:

and under the condition that the transmission of the first transmission path of the radio bearer fails, triggering survival time by the radio bearer of the terminal, or entering a survival time state by the radio bearer of the terminal, or triggering survival time by the data transmission between the terminal and the first network node, or entering a survival time state by the data transmission between the terminal and the first network node. In addition, in the following examples, the time after the transmission failure of the first transmission path of the radio bearer may be regarded as the survival time. The terminal may use an enhanced transmission scheme (e.g., a transmission path that additionally activates data transmission outside the first transmission path) at the time of the presence. In case the first transmission path of the radio bearer fails to transmit, the terminal transmits data using the second transmission path. The second transmission path may be at least two transmission paths including the first transmission path, or may be a transmission path that does not include the first transmission path and is additionally activated by the terminal for data transmission.

In one embodiment of the present application, the first transmission path satisfies any one of the following:

(1) The first transmission path is a transmission path where the terminal uniquely activates data transmission before activating the second transmission path;

(2) The first transmission path is a transmission path in which the terminal fails to first transmit data before activating the second transmission path;

(3) The first transmission path is a transmission path in which the terminal fails to transmit data before the second transmission path is activated (all).

In one embodiment of the present application, the method further comprises:

the first protocol entity of the terminal provides first indication information for a second protocol entity of the terminal, wherein the first indication information is used for indicating the second transmission path to activate data transmission, and the first protocol entity is a protocol entity corresponding to a first network node. Illustratively, the first protocol entity may be a MAC entity and the second protocol entity may be a PDCP entity.

In one embodiment of the present application, the method further comprises:

and under the condition that the first transmission path of the radio bearer fails and the third transmission path of the radio bearer fails, the terminal activates the second transmission path and/or the fourth transmission path of the radio bearer, wherein the third transmission path and the fourth transmission path are transmission paths managed by the second network node.

It is to be understood that the third transmission path and the fourth transmission path may represent a type of transmission path, i.e., the number of transmission paths included in the third transmission path and the fourth transmission path is not limited.

In one embodiment of the present application, the method further comprises:

in the case that the first transmission path and the third transmission path of the radio bearer fail, the radio bearer of the terminal triggers a time to live, or the radio bearer of the terminal enters a time to live state.

In one embodiment of the present application, the method further comprises at least one of:

the first protocol entity of the terminal provides first indication information for the second protocol entity of the terminal, wherein the first indication information is used for indicating the second transmission path to activate data transmission;

the third protocol entity of the terminal provides second indication information for the second protocol entity of the terminal, wherein the second indication information is used for indicating the fourth transmission path to activate data transmission;

wherein the first protocol entity is a protocol entity corresponding to the first network node, and the third protocol entity is a protocol entity corresponding to a second network node.

In one embodiment of the present application, the first transmission path and the third transmission path satisfy any one of the following:

(1) The first transmission path and the third transmission path are transmission paths in which the terminal activates data transmission before activating the second transmission path and/or the fourth transmission path;

(2) The first transmission path and the third transmission path are transmission paths in which the terminal fails to transmit data before activating the second transmission path and/or the fourth transmission path (all).

In one embodiment of the present application, the second transmission path is another transmission path managed by the first network node than the first transmission path; alternatively, the second transmission path is used in a lifetime and all transmission paths managed by the first network node.

In one embodiment of the present application, in case the second transmission path is all transmission paths managed by the first network node, the method further comprises:

before triggering the survival time, the terminal does not activate a data copying function for the radio bearer; and under the condition that the survival time is triggered, the terminal activates a CA data copying function for the radio bearer. The transmission path corresponding to the CA data copying function is the second transmission path.

In one embodiment of the present application, in case the second transmission path is used in a lifetime and all transmission paths managed by the first network node, the method further comprises:

before triggering the survival time, the terminal activates a DC data copy function for the radio bearer; and/or, in case of triggering the survival time, the terminal activates a CA data copy function for the radio bearer. The transmission path corresponding to the CA data copying function is the second transmission path.

Referring to fig. 3, an embodiment of the present application provides a transmission processing method, which is applied to a first network node, including:

step 301: in case of transmission failure of a first transmission path of a radio bearer, a first network node provides resources of a second transmission path of the radio bearer, wherein the first transmission path and the second transmission path are transmission paths managed by the first network node.

In one embodiment of the present application, the method further comprises:

and under the condition that the transmission of the first transmission path of the radio bearer fails, triggering survival time by the radio bearer of the first network node, or entering a survival time state by the radio bearer of the first network node, or triggering survival time by the data transmission between the first network node and the terminal, or entering a survival time state by the data transmission between the first network node and the terminal.

(1) The first network node uniquely activates a transmission path for data transmission before configuring resources of the second transmission path;

(2) The first network node first transmits the transmission path of the data failure before configuring the resource of the second transmission path;

(3) The first network node transmits a transmission path of data failure before configuring the resources of the second transmission path.

In the embodiment of the application, under the condition that the transmission of the first transmission path of the radio bearer fails, the first network node configures the resources of the second transmission path of the radio bearer, and under the DC scene, the terminal serving as the sending end can select the transmission path with the resource guarantee to transmit the copy data under the condition that the original transmission path fails, so that the stability of data transmission is improved, and further, the effective utilization of the data processing load is ensured.

Example 1

Step 1: in case an enhanced transmission scheme is used based on transmission failure information of a first transmission path associated with a radio bearer (or referred to as a target bearer) (or understood as that the terminal triggers a survival time based on the transmission failure information of the first transmission path of the radio bearer, decides to use the enhanced transmission scheme), the terminal activates a second transmission path managed by a first network node, wherein the first transmission path is a transmission path managed by the first network node.

It should be noted that the trigger survival time may be the trigger survival time of the radio bearer determined by the terminal, or the trigger survival time of the data transmission between the terminal and the first network node determined by the terminal.

Wherein the first transmission path may include any one of:

(1) The first transmission path is the only transmission path for activating data transmission before the terminal uses the enhancement scheme;

the scenario applies to a scenario in which the data copy function is not activated before the time to live is triggered.

For example, a Radio Bearer (RB) 1 has a time-to-live requirement, and the network configures leg1, leg2, leg3, leg4. Wherein Leg1, leg2 are managed by a Master Node (MN), and Leg3, leg4 are managed by a Secondary Node (SN). Only leg1 (first transmission path) is in an active state before the activation of the survival time.

In this example, in the case where it is determined to enter the surviving state based on the transmission state of leg1, the terminal activates the second transmission path managed by MN, i.e., leg2. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg1 and leg2.

(2) The first transmission path is a transmission path which fails to first transmit data before the terminal uses the enhancement scheme;

the scenario applies to a scenario in which the data copy function is activated before the time to live is triggered, which may include a scenario in which the CA Dmultiplexing and DC multiplexing are activated.

For example, a radio bearer RB1 has a time-to-live requirement, and the network is configured with leg1, leg2, leg3, and leg4. Wherein Leg1, leg2 are managed by MN, leg3, leg4 are managed by SN. Before triggering the survival time, leg1 and leg3 activate the duplicate data transfer.

In this example, if it is known that leg1 (the first transmission path managed by MN) fails to transmit data, the terminal triggers the survival time. At this time, the terminal activates the second transmission path managed by the MN, i.e., leg2. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg1 and leg2.

In this example, if it is known that leg3 (the first transmission path managed by SN) fails to transmit data, the terminal triggers the survival time. At this time, the terminal activates the second transmission path managed by SN, i.e., leg4. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg3 and leg4.

(3) The first transmission path is a transmission path in which the terminal fails to transmit data before using the enhancement scheme;

In this example, if it is known that the leg1 (the first transmission path managed by the MN) fails to transmit data, and then it is known that the leg3 (the first transmission path managed by the SN) fails to transmit data, the terminal determines that the radio bearer triggers the survival time. At this time, the terminal activates the MN-managed second transmission path, i.e., leg2, and activates the SN-managed second transmission path. I.e., leg4. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg1, leg2, leg3, leg4.

For another example, a radio bearer RB1 has a time-to-live requirement, and the network is configured with leg1, leg2, leg3, leg4. Wherein Leg1, leg2 are managed by MN, leg3, leg4 are managed by SN. Before triggering the survival time, leg1 and leg3 activate the duplicate data transfer.

In this example, if it is first known that leg1 (the first transmission path managed by MN) fails to transmit data, the terminal determines that data transmission with the first network node MN triggers the survival time. At this time, the terminal activates the second transmission path managed by the MN, i.e., leg2. In this case, the radio bearer RB1 transmits the duplicated data through leg1, leg2.

If the failure of the leg3 (the first transmission path managed by the SN) to transmit data is known again, the terminal determines that the data transmission with the second network node SN triggers the survival time. At this time, the terminal activates the second transmission path managed by SN, i.e., leg4. In this case, radio bearer RB1 would transmit duplicate data over leg1, leg2, leg3, leg4.

Wherein the second transmission path may include any one of:

(1) The second transmission path is all transmission paths associated with the radio bearer and managed by the first network node;

for example, a radio bearer RB1 has a time-to-live requirement, and the network is configured with leg1, leg2, leg3, and leg4. Where Leg1, leg2, leg3 are managed by MN and Leg4 is managed by SN. Before triggering the survival time, only leg1 (the first transmission path managed by MN) is in the active state. In this example, in the case where it is determined to enter the surviving state based on the transmission state of leg1, the terminal activates the second transmission paths managed by MN, i.e., leg2 and leg3. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg1, leg2 and leg3.

(2) The second transmission path is all transmission paths of the network configuration that can be used in the lifetime and managed by the first network node.

For example, a radio bearer RB1 has a time-to-live requirement, and the network is configured with leg1, leg2, leg3, and leg4. Where leg1, leg2, leg3 are managed by MN and leg4 is managed by SN. Only leg1 is in the activated state before triggering the survival time.

Additionally, the network side configures transmission paths that can be used at the time of the alive as leg1 and leg2. In this example, in the case where it is determined to enter the surviving state based on the transmission state of leg1, the terminal activates the second transmission path managed by MN, i.e., leg2. That is, in case the terminal triggers the survival time, the radio bearer RB1 transmits the duplicated data through leg1, leg2.

Further, in the case that the first transmission path is a transmission path of only activating data transmission before the terminal triggers the survival time, the transmission path associated with the radio bearer provided by the network side to the terminal may be a transmission path managed by the same network node; or the transmission path which can be used in the active time and the first transmission path of the network configuration belong to the same transmission path managed by the network node. In this case, the terminal activates the CA data copy function for the radio bearer.

Further, in the case where the first transmission path is that the DC data copy function is activated before the terminal triggers the survival time, the transmission path associated with the radio bearer provided by the network side to the terminal may be that each network node manages two transmission paths. Equivalently, before the time to live is triggered, the radio bearer activates the DC data copy function, and when the time to live is triggered, the terminal activates the CA data copy function for the radio bearer.

Step 2: the first protocol entity of the terminal provides first indication information for a second protocol entity of the terminal, wherein the first indication information is used for indicating the second transmission path to activate data transmission. Wherein the first protocol entity is a protocol entity corresponding to a first network node.

For example, a radio bearer RB1 has a time-to-live requirement, and the network is configured with leg1, leg2, leg3, and leg4. Wherein Leg1, leg2 are managed by MN, leg3, leg4 are managed by SN. Before triggering the survival time, leg1 and leg3 activate the duplicate data transfer. In this example, if it is known that leg1 (the first transmission path managed by MN) fails to transmit data, the terminal determines that data transmission with MN triggers survival time. At this time, the terminal activates the second transmission path managed by the MN, i.e., leg2. In this case, the primary cell group (Master Cell Group, MCG) MAC entity indicates to the PDCP entity of the radio bearer that leg2 activates data transmission.

If the failure of the leg3 (the first transmission path managed by the SN) to transmit the data is known again, the terminal judges that the data transmission between the terminal and the SN triggers the survival time. At this time, the terminal activates the second transmission path managed by SN, i.e., leg4. In this case, the secondary cell group (Secondary Cell Group, SCG) MAC entity indicates to the PDCP entity of the radio bearer that leg2 activates data transmission.

According to the transmission processing method provided by the embodiment of the application, the execution body can be a transmission processing device. In the embodiment of the present application, a transmission processing device is described by taking a transmission processing method performed by the transmission processing device as an example.
