Background technique

In related technologies, when a terminal performs uplink data transmission, it may use pre-periodically allocated resources for data transmission. The network side device pre-configures one or more configuration authorization groups for the terminal, and each configuration authorization group corresponds to at least one HARQ (Hybrid Automatic Repeat Request) process.

When the configuration authorization group #1 is released, the HARQ process ID of the configuration authorization group #2 will change from HARQ processes 5, 6, and 7 to HARQ processes 3, 4, and 5 accordingly; when there is a retransmission packet in HARQ process 5 When the process changes, the terminal cannot complete subsequent retransmissions.

Summary of the invention

The embodiments of the present application provide a data transmission method and device to solve the problem of how to perform HARQ process data transmission after an RRC message occurs, activation or deactivation of a configuration authorization group.

In the first aspect, an embodiment of the present application provides a data transmission method, the method including:

After receiving the notification message for updating the configuration authorization group, the terminal processes the data that needs to be transmitted.

In the above method, after the terminal determines to configure multiple configuration authorization groups, it processes the data to be transmitted after receiving the notification message to update the configuration authorization group. After receiving the notification message to update the configuration authorization group, the terminal determines the configuration authorization that needs to be updated. Group and process the HARQ process data transmission in the configuration authorization group that needs to be updated. After receiving the notification message for the update configuration authorization group, the terminal clarifies how to process the HARQ process data transmission in the configuration authorization group that needs to be updated.

In a possible implementation manner, the terminal receives the notification message for updating the configuration authorization group in the following manner:

The terminal receives an RRC message used to instruct to release or add one or more groups of configuration authorization groups; or

The terminal receives DCI (Downlink Control Information) used to instruct to deactivate or activate one or more groups of configuration authorization groups.

In the above method, the notification message for explicitly updating the configuration authorization group includes the RRC message indicating the release or addition of one or more sets of configuration authorization groups and the DCI indicating the deactivation or activation of one or more sets of configuration authorization groups. Therefore, the terminal receives the above After the RRC message and/or the aforementioned DCI, it is determined that the configuration authorization group needs to be updated, and the terminal knows when the configuration authorization group needs to be updated.

In a possible implementation, when the terminal processes the data to be transmitted:

The terminal processes the data to be transmitted according to the running status of the configuration authorization timer of the HARQ process in the configuration authorization group that needs to be updated.

In a possible implementation manner, when the terminal processes the data to be transmitted according to the running status of the configuration authorization timer of the HARQ process in the configuration authorization packet that needs to be updated:

If the terminal determines that the configuration grant timer of the HARQ process P in the configuration grant group is running, and the HARQ process P data retransmission schedule is received, then execute the HARQ process P data retransmission; or

If the terminal determines that the configuration authorization timer of the HARQ process P in the configuration authorization group stops running or times out, the HARQ process P is changed to the HARQ process Q, and the HARQ process Q data transmission is performed, where P and Q are An integer greater than or equal to 0, and P is not equal to Q.

In the above method, the terminal determines how to process the HARQ process transmission data according to the running status of the HARQ process configuration authorization timer in the configuration authorization group that needs to be updated. When the HARQ process configuration authorization timer is running, when the data retransmission schedule is received, the current HARQ process data retransmission is performed; or the HARQ process configuration authorization timer stops running or times out to determine the current HARQ process data The transmission is successful, and the current HARQ process is updated, and the changed HARQ process data transmission is performed.

In the above method, after receiving the notification message of the updated configuration authorization group, the terminal determines that the HARQ process in the updated configuration authorization group has changed, and if it receives a scheduling instruction to execute the HARQ process data retransmission before the change, it will remain unchanged. The data of the previous HARQ process is transferred to the changed HARQ process, and the terminal performs the data transmission of the changed HARQ process. At this time, the data of the HARQ process before the change is transmitted; or the HARQ process before the execution is received After the scheduling instruction for data retransmission, the data in the HARQ process before the change is deleted, and the data transmission of the HARQ process after the change is performed. At this time, the new data is transmitted in the HARQ process after the change.

detailed description

Hereinafter, some terms in the embodiments of the present application will be explained to facilitate the understanding of those skilled in the art.

(1) In the embodiments of this application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand their meaning.

(2) The term "multiple" in the embodiments of the present application refers to two or more than two, and other quantifiers are similar.

(3) "and/or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B alone exists. Happening. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

At present, the use of uplink resources by the terminal is dynamically scheduled or non-dynamically scheduled by the network side equipment. In the dynamic scheduling scenario: the network side device allocates uplink resources for the terminal and indicates the uplink resources allocated by the terminal so that the terminal can transmit data on the allocated uplink resources; in the non-dynamic scheduling scenario: the network side device configures the terminal Authorization group, the configured authorization group becomes the configuration authorization group, which can also be called configured grant.

Among them, the configuration grant is a transmission method of pre-periodically allocated resources introduced by NR (New Radio) for UL (Uplink) data. Configuration authorization includes two methods: configured authorization type 1 (configured grant Type 1) and configured authorization type 2 (configured grant Type 2); among them, configuration authorization type 2 and LTE (Long Term Evolution) SPS (Semi-Persistent Scheduling) , Semi-persistent scheduling) working mechanism is the same. In NR, the network side equipment is pre-configured with UL resources to facilitate services that require high latency (such as URLLC (Ultra Reliable Low Latency Communications)) or services with a relatively regular format (such as VoIP services). Transmission on the configured UL resource.

The similarity of the two scheduling methods, configuration authorization type 1 and configuration authorization type 2, is that the base station allocates periodic resource locations in advance, and the terminal performs data transmission according to the resource locations allocated by the base station. The difference is: Configuration authorization type 1 is RRC configuration resource location, MCS (Modulation Coding Scheme) mode, RB (Radio Block, radio resource block) size, number of HARQ processes, period, etc., and no physical layer is required. The activation or deactivation process takes effect after the RRC configuration, and the data is transmitted on the response configuration resource. As shown in Figure 1A, it is the data sending process of the configuration authorization type 1. The configuration authorization type 2 is configured by the RRC to configure the resource location, the number of HARQ processes, and the period, but it does not configure the RB size. The MCS method requires the physical layer to send DCI to activate or deactivate the resource, as shown in Figure 1B. Configure the data sending process of authorization type 2. The HARQ process in configuration authorization type 1 and configuration authorization type 2 ranges from 0 to N-1. Where N is the number of HARQ processes scheduled by RRC for configuration authorization type 1 and configuration authorization type 2, so the HARQ process also includes 0.

It can be seen from the above content that in the same serving cell, the network side device configures multiple configuration authorization groups for the terminal, and the following configuration scheme can be used for the coordination process of the multiple configuration authorization groups.

Configuration scheme 1: For different service characteristics, such as supporting VoIP and URLLC at the same time, but due to different service attributes: VoIP has a longer delay and lower reliability requirements, so it is configured for a longer period, and the configured MCS is relatively compared Large; URLLC has higher requirements for delay and reliability, so the period setting will be shorter, and the MCS setting will be smaller. Therefore, multiple configuration authorization groups can be different periods, different resource durations, different MCSs, and different resource start positions. As shown in FIG. 2A, it is a schematic diagram of the first configuration authorization groups with different configurations.

Configuration scheme 2: Since there will be a certain delay jitter when the service arrives, if only one set of configuration authorization is configured, the terminal misses a resource location and needs to wait until the next cycle to transmit, so the data transmission delay increases, and the setting is different After resources are configured, the terminal can select the nearest available resource to send after the service arrives, thereby reducing transmission delay. Therefore, multiple configuration authorization groups can be the same period, the same resource duration, the same MCS, and different resource start positions; as shown in FIG. 2B, it is a schematic diagram of the second configuration authorization group with different configurations.

In related technologies, it has been pointed out that the terminal determines how to configure multiple configuration authorization groups, but when an RRC message (such as RRC release, or adding one or more configuration authorization groups) occurs to a configured configuration authorization group in the terminal, a group is activated. Or after multiple groups of configuration authorization groups or deactivation of one or more groups of configuration authorization groups, the HARQ process ID contained in the configuration authorization group will also change accordingly. Therefore, the corresponding HARQ process ID cannot be found when the HARQ process data retransmission is not changed. During the process, the terminal cannot perform data retransmission, and the terminal’s data transmission behavior is unclear.

Based on the above content, this application provides a data transmission method and device to solve the problem that when the terminal receives the RRC to release one or more configuration authorization groups, or the RRC message instructs to add one or more configuration authorization groups, and activate one group. Or multiple configuration authorization groups, or after deactivating one or more configuration authorization groups, the HARQ process in the configuration authorization group will occur. When the network side equipment schedules the terminal for new data transmission or data retransmission, how does the terminal execute the data? Transmission problem. In this application: the terminal first determines multiple configuration authorization groups configured by the network side device, and after receiving the notification message for updating the configuration authorization group, the terminal can first determine the configuration authorization timer of the HARQ process in the configuration authorization group that needs to be updated According to the running status of the configuration authorization timer, process the data that needs to be transmitted; or after the terminal receives the notification message to update the configuration authorization group, it determines that the HARQ process in the configuration authorization group that needs to be updated changes, the terminal When receiving the retransmission scheduling request, the data that needs to be retransmitted in the HARQ process before the change is transferred to the changed HARQ process for transmission; or after the HARQ process in the configuration authorization group that needs to be updated is determined to be changed, the terminal When receiving the retransmission scheduling request, the terminal deletes the data in the HARQ process before the change, does not perform retransmission, and performs new data transmission in the HARQ process after the change. After the terminal determines that the process in the configuration authorization group is changed, whether it is receiving the data retransmission schedule or the new data transmission schedule, the terminal knows how to transmit data and improve the data transmission efficiency.

In the embodiment of this application, the terminal is a device with wireless communication function, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air ( For example, airplanes, balloons, satellites, etc.).

The network side device can be a base station, which is a device that provides wireless communication functions for the terminal, including but not limited to: gNB in 5G, radio network controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (for example, Home Evolved NodeB, or Home Node B, HNB), BaseBand Unit (BBU), transmission point (Transmitting and Receiving Point, TRP), Transmitting Point (TP), mobile switching center, etc. The base station in this application may also be a device that provides wireless communication functions for terminals in other communication systems that may appear in the future.

In order to make the purpose, technical solutions, and advantages of the application more clear, the application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. . Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

As shown in FIG. 3, a flow chart of a data transmission method provided by an embodiment of this application includes the following steps:

Step 300: The terminal determines to configure multiple configuration authorization groups;

Step 301: After receiving the notification message for updating the configuration authorization group, the terminal processes the data to be transmitted.

In the above method, after the terminal determines to configure multiple configuration authorization groups, it processes the data to be transmitted after receiving the notification message to update the configuration authorization group. After receiving the notification message to update the configuration authorization group, the terminal determines the configuration authorization that needs to be updated. Group and process the HARQ process data transmission in the configuration authorization group that needs to be updated. After receiving the notification message for the update configuration authorization group, the terminal clarifies how to process the HARQ process data transmission in the configuration authorization group that needs to be updated.

In this application, the terminal receives the notification message for updating the configuration authorization group in the following manner:

The terminal receives a radio resource control RRC message used to instruct to release or add one or more groups of configuration authorization groups; or

The terminal receives the downlink control information DCI used to indicate the deactivation or activation of one or more groups of configuration authorization groups.

Since the configuration authorization group includes at least one of configuration authorization type 1 and configuration authorization type 2, the notification message for updating the configuration authorization group includes RRC messages for configuration authorization type 1 and configuration authorization type 2 and for configuration authorization type 2. DCI message.

In practical applications, for the configuration authorization group of configuration authorization type 1, after receiving an RRC message for instructing to release or add one or more configuration authorization groups, the configuration authorization group that needs to be updated can be determined; or For the configuration authorization group of configuration authorization type 2, after receiving an RRC message for instructing to release or add one or more configuration authorization groups, determine the configuration authorization group that needs to be updated; or for the configuration of configuration authorization type 2 In the case of authorization grouping, after receiving the DCI that activates or deactivates one or more groups of configuration authorizations, determine the configuration authorization group that needs to be updated.

In this application, after receiving at least one of the notification messages for updating the configuration authorization packet, the terminal may refer to the configuration authorization timer of the HARQ process in the configuration authorization packet that needs to be updated to determine whether to update when processing the data to be transmitted. Configure the HARQ in the authorization group, or directly update the HARQ process in the configuration authorization group that needs to be updated. It is introduced in detail through the following two embodiments:

Embodiment 1: Refer to the running status of the configuration authorization timer of the HARQ process in the configuration authorization group that needs to be updated.

In this application, the network side device configures multiple authorization configuration groups for the terminal, and each configuration authorization group corresponds to at least one HARQ process. As shown in FIG. 4, it is a schematic diagram of the configuration authorization group configured by the network side device for the terminal.

When the terminal receives the notification message for updating the configuration authorization group sent by the network side device, it determines the configuration authorization group that needs to be updated. Further, the terminal judges the operation status of the configuration authorization timer of the HARQ process in the configuration authorization group that needs to be updated, and processes the data to be transmitted according to the operation status of the timer.

When the terminal processes the data that needs to be transmitted according to the running status of the timer: if the terminal determines that the configuration authorization timer of the HARQ process P in the configuration authorization packet that needs to be updated is running, and the HARQ process P data retransmission schedule is received, execute HARQ process P data retransmission; or if the terminal determines that the configuration authorization timer of the HARQ process P in the configuration authorization packet that needs to be updated expires or stops, the HARQ process P is changed to the HARQ process Q, and the HARQ process Q data transmission is performed, When the HARQ process Q data transmission is performed, the new HARQ process Q data transmission is performed. Among them, P and Q are integers greater than or equal to 0, and P is not equal to Q.

In practical applications, the starting conditions for configuring the authorization timer include:

The current HARQ process is a new transmission/retransmission authorized by the configuration;

The current HARQ process is a new transmission or retransmission that is dynamically authorized and scheduled, but it is configured for configuration authorization, that is, the HARQ process ID belongs to the HARQ process ID range of the configuration authorization.

CS-RNTI (Configured Scheduling-Radio Network Temporary Identifier) scheduled new transmission/retransmission.

It should be noted that when the configuration authorization timer of the HARQ process runs within the set time, the HARQ process remains unchanged; when the configuration authorization timer of the HARQ process times out or stops, it is determined that the data transmission is successful, and if the update configuration authorization is received For the grouped notification message, the HARQ process in the configuration authorization group that needs to be updated is recalculated according to formula 1, otherwise the HARQ process in the configuration authorization group remains unchanged.

Formula 1:

UL HARQ ID=[floor(CURRENT_symbol/periodicity+timeDomainOffset)]%M _i +Offset _i

Wherein, M _i represents the number of i-th HARQ process configuration authorization packet configuration; Offset represents the offset configuration packet start authorization in HARQ process ID, Offset may be made of RRC (Radio Resource Control, RRC) signaling The configuration can also be determined according to the number of HARQ processes configured in the configuration authorization group, where the configuration authorization group #0 is represented by Offset ₀ , and Offset ₀ = 0. When i>0,

M _j represents the number of HARQ processes configured in the jth configuration authorization group, M is used to represent the number of HARQ processes configured in the configuration authorization group, and i and j are used to represent different configuration authorization groups.

Assume that the configuration authorization group configured by the network side device for the terminal is the configuration authorization group corresponding to configuration authorization type 1, and the notification message for updating the configuration authorization group is to release the configuration authorization group #1, and the configuration authorization group that needs to be updated at this time is the configuration authorization group #2. It can be seen from FIG. 4 that configuration authorization group #1 corresponds to HARQ process 3 and HARQ process 4; configuration authorization group 2 corresponds to HARQ process 5, HARQ process 6 and HARQ process 7.

After determining the configuration authorization group that needs to be updated, the terminal judges the operation of the configuration authorization timer of HARQ process 5 in configuration authorization group #2. If the configuration authorization timer of HARQ process 5 is running, it waits for the configuration of HARQ process 5 After the authorization timer expires or stops, the HARQ process is recalculated and updated.

If the HARQ process 5 data retransmission schedule is received during the operation of the HARQ process 5 configuration authorization timer, the terminal continues to use the HARQ process 5 to perform the HARQ process 5 data retransmission, and restarts the HARQ process 5 configuration authorization timer. Until the configuration authorization timer of HARQ process 5 stops or expires, the terminal recalculates and updates the HARQ process according to the above formula. At this time, because configuration authorization group #1 is released, HARQ process 5 is updated to HARQ process 3.

After determining that the configuration authorization timer of HARQ process 5 has expired or stopped, continue to determine the operation of the configuration authorization timer of HARQ process 6. If the configuration authorization timer of HARQ process 6 is running, HARQ process 6 will not be updated. Update HARQ process 5.

Assume that the configuration authorization group configured by the network side device for the terminal is the configuration authorization group corresponding to configuration authorization type 2, and the notification message for updating the configuration authorization group is deactivation configuration authorization group #1, activation configuration authorization group #2, and it needs to be updated at this time The configuration authorization group of is the configuration authorization group #2. The specific update process is similar to the above situation and will not be repeated here.

It should be noted that the configuration authorization timer is set for each HARQ process. In the HARQ process update, each HARQ process only determines whether to update the HARQ process according to the running status of the corresponding configuration authorization timer.

As shown in Figure 5, a flow chart of an overall data transmission method provided by this application includes the following steps:

Step 500: The terminal determines to configure multiple configuration authorization groups;

Step 501: After receiving the notification message for updating the configuration authorization group, the terminal determines the configuration authorization group that needs to be updated;

In step 502, the terminal determines whether the configuration authorization timer of the HARQ process P in the configuration authorization group that needs to be updated is running, if so, perform step 503, otherwise, perform step 504;

Step 503, the HARQ process P remains unchanged;

Step 504: Change the HARQ process P to the HARQ process Q.

In the above method, the terminal determines how to process the HARQ process transmission data according to the running status of the HARQ process configuration authorization timer in the configuration authorization group that needs to be updated. When the HARQ process configuration authorization timer is running, when the data retransmission schedule is received, the current HARQ process data retransmission is performed; or the HARQ process configuration authorization timer stops running or times out to determine the current HARQ process data The transmission is successful, and the current HARQ process is updated, and the changed HARQ process data transmission is performed. After receiving the notification message for updating the configuration authorization packet, the terminal first determines the running status of the configuration authorization timer of the HARQ process, and further determines how to transmit data, so that the terminal has a better understanding of how to perform data transmission.

Embodiment 2: The terminal directly updates the HARQ process in the configuration authorization group that needs to be updated.

In this application, the network side device configures multiple configuration authorization groups for the terminal, and each configuration authorization group corresponds to at least one HARQ process, as shown in FIG. 4.

When receiving the notification message for updating the configuration authorization group sent by the network side device configuration, the terminal determines the configuration authorization group that needs to be updated, recalculates and updates the HARQ process of the configuration authorization group that needs to be updated. Further, the terminal processes the data to be transmitted according to the received data transmission scheduling instruction. If the terminal receives the data retransmission scheduling instruction, the terminal can retransmit data in the changed HARQ process, or delete the data that needs to be retransmitted, and perform new data transmission in the changed HARQ process, see below for details Two situations are described.

Case 1: After receiving the data retransmission instruction, the data is retransmitted in the changed HARQ process.

In this application, the terminal determines that the HARQ process P is changed to HARQ process Q, and after receiving the data retransmission schedule of HARQ process P, transfers the data in HARQ process P to HARQ process Q, and Perform the HARQ process Q data transmission, where P and Q are integers greater than or equal to 0, and P is not equal to Q.

As shown in Figure 4, configure authorization group #0 to configure HARQ process 0, HARQ process 1, and HARQ process 2; configure authorization group #1 to configure HARQ process 3 and HARQ process 4; configure authorization group #2 to configure HARQ process 5, HARQ process 6, HARQ process 7.

Assuming that after configuration authorization group #1 is released, or after being released by DCI, Offset ₂ = 3, the HARQ process in the configuration authorization group that needs to be updated is recalculated according to formula 1. Therefore, HARQ process 5, HARQ process 6, and HARQ process 7 of authorization group #2 will be changed to HARQ process 3, HARQ process 4, and HARQ process 5 respectively.

If a MAC PDU (Media Access Control Packet Data Unit) needs to be retransmitted in HARQ process 5 of the terminal, the terminal transfers the MAC PDU in HARQ process 5 to the changed HARQ process 3 and executes HARQ Process 3 data transmission. At this time, the data transmitted in HARQ process 3 is the MAC PDU of the original HARQ process 5.

As shown in FIG. 6, a flow chart of the second overall method for data transmission provided in this embodiment of the application includes the following steps:

Step 600: The terminal determines to configure multiple configuration authorization groups;

Step 601: After receiving the notification message for updating the configuration authorization group, the terminal determines the configuration authorization group that needs to be updated;

Step 602: The terminal recalculates the HARQ process in the configuration authorization group that needs to be updated, and changes the original HARQ process to the calculated HARQ process;

Step 603: After receiving the data retransmission instruction for the original HARQ process, the terminal transfers the data in the original HARQ process to the changed HARQ process;

In step 604, the terminal performs a later HARQ process data transmission.

Case 2: After receiving the data retransmission instruction, the data in the HARQ process before the change is deleted, the data retransmission is not performed, and the new data transmission is performed in the HARQ process after the change.

After determining that the HARQ process P is changed to HARQ process Q, and after receiving the HARQ process P data retransmission schedule, the terminal deletes the data in the HARQ process P, and performs the HARQ process Q data transmission, where P And Q is an integer greater than or equal to 0, and P is not equal to Q.

As shown in Figure 4, configure authorization group #0 to configure HARQ process 0, HARQ process 1, and HARQ process 2; configure authorization group #1 to configure HARQ process 3 and HARQ process 4; configure authorization group #2 to configure HARQ process 5, HARQ process 6, HARQ process 7.

Assuming that after configuration authorization group #1 is released, or after being released by DCI, Offset ₂ = 3, the HARQ process in the configuration authorization group that needs to be updated is recalculated according to formula 1. Therefore, HARQ process 5, HARQ process 6, and HARQ process 7 of authorization group #2 will be changed to HARQ process 3, HARQ process 4, and HARQ process 5 respectively.

If there is a MAC PDU in the HARQ process 5 of the terminal that needs to be retransmitted, the terminal deletes the MAC PDU in the HARQ process 5 and performs data transmission in the HARQ process 3. At this time, the data transmitted in the HARQ process 3 needs to be transmitted with new data.

As shown in FIG. 7, a flow chart of the third overall method of data transmission provided by this embodiment of the application includes the following steps:

Step 700: The terminal determines to configure multiple configuration authorization groups;

Step 701: After receiving a notification message for updating a configuration authorization group, the terminal determines a configuration authorization group that needs to be updated;

Step 702: The terminal recalculates the HARQ process in the configuration authorization group that needs to be updated, and changes the original HARQ process to the calculated HARQ process;

Step 703: After receiving the data retransmission instruction for the original HARQ process, the terminal deletes the data in the original HARQ process, and executes a new HARQ process data transmission.

In the above method, after receiving the notification message for updating the configuration authorization group, the terminal determines that the HARQ process in the updated configuration authorization group has changed, and if it receives a scheduling instruction to execute the HARQ process data retransmission before the change, it will remain unchanged. The data of the previous HARQ process is transferred to the changed HARQ process, and the terminal performs the data transmission of the changed HARQ process.
