Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: the present invention relates to a Mobile terminal, and more particularly to a Mobile terminal, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a robot, a vehicle, and other terminal-side devices. The network side device 12 may be a Transmission Reception Point (TRP), and the embodiment of the present invention may be applied to a multi-TRP scenario. Further, the network side device 12 may access network devices, such as base stations, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device may be an Access Point (AP); the network side device may also be a Central Unit (CU). It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a data transmission method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

step 201, the terminal caches data of a logical channel corresponding to the first service bearer;

step 202, the terminal limits the data transmission in a transmission time window according to a Logical channel priority parameter (LCP) of the Logical channel, where the transmission time window is a data transmission time window required according to the service characteristics of the first service bearer.

The first service bearer may be a service bearer transmitted by a required data transmission time window, for example: traffic bearers required to be transmitted within a specified time in the industrial internet may be referred to as on-time transmission (on time transmission) traffic. The above logical channels may also be referred to as specific logical channels.

The data transmission time window required according to the service characteristic of the first service bearer may be configured in advance, or configured by a protocol agreement or a network side.

The logical channel priority parameter may be configured by the network side device to the terminal, and the configuration may be a dynamic, static, or semi-static configuration, which is not limited herein.

The terminal may limit the data transmission in the transmission time window according to the logical channel priority parameter of the logical channel, that is, the data is transmitted in the transmission time window, and the buffered data is not transmitted until the transmission time window arrives.

The transmission data may be the data transmitted to the network side device, so that the network side device may receive the data within the transmission time window.

In the embodiment of the invention, the data can be transmitted in the transmission time window through the steps, and the cached data is not transmitted before the transmission time window arrives, so that the requirement of the service is met, and the service transmission performance is improved.

As an optional implementation manner, the logical channel priority parameter includes at least one of the following parameters:

a token bucket suspend indication, a token bucket start time indication, a PBR adjustment parameter, a priority adjustment parameter, and a transmission prohibition parameter.

The token bucket suspension indication may be RRC signaling or MAC layer signaling or physical layer signaling. The token bucket suspend indication may have only one indication: the token bucket is suspended; two indications may also be included: the token bucket is suspended, or the token bucket is started. In addition, configuring the token bucket suspension indication may be understood as configuring a token bucket suspension mechanism for the terminal by the network side device. The token bucket starting indication indicates that the terminal temporarily enables the token bucket under the condition that the token bucket suspension mechanism is effective, and the subsequent network side equipment can send the token bucket suspension indication to indicate that the terminal suspends the token bucket.

In addition, in the embodiment of the present invention, after receiving the token bucket suspension indication, the terminal performs data transmission according to a token bucket mechanism agreed by a protocol, for example: after receiving the token bucket suspension indication, the terminal may calculate Bj according to a token bucket mechanism agreed by the protocol, that is, Bj ═ PBR × T, until the upper limit Bj ═ PBR × BSD. Wherein, BSD is token bucket Size Duration (bucket Size Duration), and T represents time. The token bucket may actually have a value only when the token bucket is suspended, but the data to be transmitted of the logical channel is ignored when the transmission data organization is performed (for example, the virtual value is Bj ═ 0), and when the token bucket is started, the data transmission is performed according to the token bucket mechanism agreed by the protocol.

The token bucket start time indication may indicate a start time or a hang time of the token bucket.

The PBR adjustment parameter may be for adjusting the PBR, or the PBR adjustment parameter includes a plurality of PBRs, so that the user can adjust the PBR when selecting between the plurality of PBRs.

The priority adjustment parameter may be used for adjusting the priority, or the priority adjustment parameter includes a plurality of priorities, so that the user can adjust the priority when selecting among the plurality of priorities.

The transmission prohibition parameter may be used only for prohibiting transmission, or may have two indication results, one indicating prohibition of transmission and the other indicating permission of transmission.

In this embodiment, the terminal may perform data transmission within the transmission time window according to the logical channel priority parameter. For example: and adjusting the transmission starting point of the logical channel data through the logical channel priority parameter, and transmitting the data of the logical channel in the transmission time window.

Further, the data transmission may be performed according to at least one of the token bucket, the PBR and the priority, such as determining the data amount to be transmitted according to at least one of the token bucket, the PBR and the priority, and performing the transmission according to the determined data amount and priority.

It should be noted that, some or all of the token bucket suspension indication, the token bucket start time indication, the PBR adjustment parameter, the priority adjustment parameter, and the transmission prohibition parameter may be configured by the network side, or some or all may be agreed by a protocol, and the like, which is not limited herein.

Optionally, the token bucket suspension indication is configured for the traffic bearer, or the token bucket suspension indication is configured for a PDCP layer of the traffic bearer, or the token bucket suspension indication is configured for a logical channel corresponding to the traffic bearer.

The service Bearer may be a Data Radio Bearer (DRB), for example: the network side device configures a token bucket suspension indication for a service bearer requiring data transmission within a specified time window, where the indication may be configured for a DRB, or configured for a PDCP layer corresponding to the DRB, or configured for a logical channel corresponding to the DRB.

Similarly, the token bucket start time indication may also be configured for the service bearer, or the token bucket start time indication is configured for a packet data convergence protocol PDCP layer of the service bearer, or the token bucket start time indication is configured for a logical channel corresponding to the service bearer.

In this embodiment, the token bucket pending indication has only one indication, i.e., indicates that the token bucket for the logical channel is pending.

In this embodiment, it may be achieved that the token bucket is only started at the transmission time window and used within the transmission time window. For example: the network side only indicates the token bucket to be suspended, the terminal self evaluates whether the logical channel with the cache data reaches a transmission time window when uplink resources are allocated, and if the initial transmission time of the logical channel data is not reached, the data of the logical channel is not mapped to the allocated uplink resources for transmission; if the transmission time window of the logical channel data is reached (if the initial transmission time is reached or exceeded), the token bucket is released from the suspension, the token bucket is started, and the uplink data of the logical channel is mapped to the uplink transmission resource for transmission.

and the terminal suspends the token bucket of the logical channel under the condition of receiving the token bucket suspension indication of the first indication content, and starts the token bucket under the condition of receiving the token bucket suspension indication of the second indication content.

In this embodiment, the token bucket suspend indication has two indications, namely suspend and start, so that the network side can flexibly configure data transmission of the terminal through the token bucket suspend indication.

For example: the network side can respectively indicate that the token bucket is suspended and the token bucket is started, and the terminal suspends the token bucket after receiving the indication indicating that the token bucket is suspended, namely the token bucket can actually have numerical values, but ignores the data to be transmitted of the logical channel when the data transmission organization is carried out (for example, if the virtual value is Bj ═ 0); and after the terminal receives the indication of starting the token bucket, mapping the data to be transmitted of the logic channel to the MAC PDU by using the actually calculated token bucket for transmission on the uplink resource.

Optionally, the terminal suspends the token bucket of the logical channel when receiving the token bucket suspension indication for the first indication content, starts the token bucket if the transmission time window is reached, suspends the token bucket after the cached data is sent out or the transmission time window is finished, and starts the token bucket when receiving the token bucket suspension indication for the second indication content.

In this embodiment, the token bucket suspend indication has two indications, namely suspend and start, and further, the terminal can decide to start the token bucket by itself, so that the data transmission of the terminal is more flexible.

For example: the network side can respectively indicate the token bucket to be suspended and the token bucket to be started, and after the terminal receives the indication of the token bucket to be suspended, if the terminal determines that data to be sent in the cached logic channel has a data packet reaching a transmission window, the token bucket is temporarily started, and the data packet is mapped to uplink resources to be sent. The token bucket continues to be suspended after the data packet is sent. After receiving the indication of token bucket start, the token bucket is started in a conventional manner.

Optionally, the token bucket suspension indication is indicated by RRC signaling, and the RRC signaling configures the token bucket suspension indication to suspend or start the token bucket; or the like, or, alternatively,

In this embodiment, the token bucket suspend instruction may be applied to only one instruction, that is, only one instruction to suspend the token bucket, or may be applied to two instructions, that is, to instruct to suspend or start the token bucket.

The token bucket starting time may be configured for a DRB, or configured for a PDCP layer corresponding to the DRB, or configured for a logical channel corresponding to the DRB.

In addition, the start-up time may be periodic or aperiodic.

Optionally, the token bucket start time indicator is configured to indicate a periodic start time of the token bucket, and the terminal starts the token bucket at the start of each period according to the token bucket start time indicator and suspends the token bucket after the cached data is sent.

The periodic starting time of the token bucket may be that the token bucket is started periodically, and the starting point of each period is located within the transmission time window.

For example: and the network side equipment indicates the starting time of the periodic token bucket according to the transmission characteristics of the terminal service data. And the terminal starts the token bucket when reaching the starting point of each period, and suspends the token bucket after finishing transmitting the data of the corresponding logical channel in the cache until the starting point of the next token bucket starting period.

Optionally, the token bucket start time indication is used to indicate a periodic token bucket start time window, and the terminal starts the token bucket in the token bucket start time window according to the token bucket start time indication and suspends the token bucket after the token bucket start time window is ended.

The token bucket starting time window is different from the periodic starting time in that the token bucket starting time window comprises a transmission window length, namely the time length of data transmission. Therefore, the data transmission of the terminal can be controlled more accurately.

For example: and the network side equipment indicates a periodic token bucket to start a time window according to the transmission characteristics of the terminal service data, and the time window is empty, and has a transmission window length indication except a period and a period starting point indication. The terminal starts the token bucket when reaching the beginning of each period, and the data of the corresponding logical channel in the buffer can only be transmitted in the indicated time window. And after the token bucket starting time window is finished, suspending the token bucket until the starting point of the next token bucket starting period.

Optionally, the token bucket start time indication is used to indicate a token bucket prohibition timer, the token bucket prohibition timer is started at a transmission time window end time point or when the data is sent, the terminal suspends the token bucket during the running period of the token bucket prohibition timer, and starts the token bucket after the token bucket prohibition timer is overtime.

In this embodiment, the terminal starts the token bucket prohibit timer at the end time point of the transmission time window or after completing the transmission of the buffered logical channel data, and during the operation period of the token bucket prohibit timer, the terminal does not transmit the data of the logical channel even if there is uplink resource.

When the first PBR is used, the mapping of the data to the uplink transmission resource may be that the PBR is 0, which is not limited to, for example: the protocol may agree that a certain value of PBR is taken to indicate that the terminal is not transmitting. In addition, the first PBR may be one or more PBRs. That is, the network side device configures at least two PBRs for the above logical channel of the terminal, for example, the configured PBR is 0 and the PBR corresponding to the QoS requirement of the service bearer, that is, the conventional PBR.

Further, which PBR the terminal uses may be terminal-independent or may be a network-side device indication.

Optionally, the terminal uses the second PBR within the transmission time window, and the terminal uses the first PBR before the transmission time window arrives to be determined by the terminal.

This embodiment may enable the terminal to decide which PBR value to use on its own. When the data of the logical channel does not reach the transmission time window, the terminal uses the first PBR, and the calculated Bj is 0, even if the priority of the logical channel is high, the terminal does not preferentially transmit the data of the logical channel when mapping the data to the uplink resource; and when the logical channel data reaches the transmission time window, the terminal uses the second PBR value to carry out data mapping and transmission.

Optionally, the terminal uses the second PBR within the transmission time window, and the terminal uses the first PBR to be indicated by the network side signaling before the transmission time window arrives.

This embodiment may enable the indication of which PBR to use by the network side, for example: the network side may indicate which PBR value the terminal uses through MAC layer signaling or physical layer commands. When the terminal uses the first PBR, the terminal does not map the buffer data of the logic channel to the uplink transmission resource, and when the terminal uses the second PBR, the buffer data of the logic channel is mapped to the uplink transmission resource according to the priority of the logic channel.

In this embodiment, a priority adjustment mechanism is introduced, where the first priority may be the lowest priority supported by the terminal, or a priority that is not used for data transmission is agreed by the protocol. And the first priority may be one or more priorities. For example: the network side configures at least two priority indications, such as a lowest priority and a normal priority, for the logical channel for the terminal, where the normal priority corresponds to a service bearer QoS requirement corresponding to the logical channel.

Further, which priority the terminal uses may be terminal-independent or may be network-side device indication.

Optionally, the terminal uses the second priority within the transmission time window, and the terminal uses the first priority before the transmission time window arrives.

In this embodiment, it is possible to realize that the terminal decides which priority to use on its own. The terminal uses the first priority when the logical channel data does not reach the transmission time window, so that the data of the logical channel cannot be mapped onto the uplink transmission resource even when the uplink resource exists; and when the logical channel data reaches the transmission time window, the terminal uses the second priority to carry out data mapping and transmission.

Optionally, the terminal uses the second priority within the transmission time window, and the terminal uses the first priority to be indicated by the network side signaling before the transmission time window arrives.

In this embodiment, it may be implemented that the network side indicates which priority to use, for example: the network side equipment indicates the terminal to use the logical channel priority through MAC layer signaling or physical layer commands.

In this embodiment, in one scenario, the transmission prohibition parameter is only used to indicate prohibition of transmission, and in another scenario, the transmission prohibition parameter may be used to indicate prohibition of transmission and indicate initiation of transmission, and of course, only one of them may be indicated in the case of one indication content.

In addition, the transmission prohibition parameter may be configured by RRC signaling, MAC layer signaling, or physical layer signaling. For example: RRC signaling configures a logical channel or a bearer for enabling a transmission forbidding mechanism, and MAC layer signaling indicates that the data of the logical channel or the first service bearer is forbidden to be transmitted or starts to be transmitted; or, in the physical layer scheduling command, indicating that the currently scheduled uplink resource cannot carry the data of the logical channel.

It should be noted that the indication time for prohibiting transmission of the parameter may be a periodic indication time or a periodic indication time window, which may be specifically referred to the token bucket start time indication. Or the terminal may dynamically indicate the network side device, or automatically decide whether to use the transmission prohibition parameter.

In the embodiment of the invention, a terminal caches data of a logic channel corresponding to a first service bearer; the terminal limits the data to be transmitted in a transmission time window according to the logic channel priority parameter of the logic channel, and does not transmit the cached data before the transmission time window arrives; wherein the transmission time window is a data transmission time window required according to the service characteristics of the first service bearer. Therefore, data can be transmitted in the transmission time window, and the service transmission performance is improved.

Referring to fig. 3, fig. 3 is a flowchart of a parameter configuration method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, a network side device configures a logical channel priority parameter of a logical channel for a terminal, where the logical channel is a logical channel corresponding to a first service bearer, and the logical channel priority parameter is used for the terminal to limit transmission of data of the logical channel within a transmission time window, where the transmission time window is a data transmission time window required according to service characteristics of the first service bearer.

The above-mentioned logical channel priority parameter may be used for the terminal to limit the transmission of the data of the logical channel in the transmission time window, where the logical channel priority parameter is used for the terminal to transmit the data of the logical channel in the transmission time window, and the data of the logical channel is not transmitted before the transmission time window arrives.

It should be noted that, this embodiment is used as an implementation of the network side device corresponding to the embodiment shown in fig. 2, and specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 2, so that, in order to avoid repeated description, the embodiment is not described again, and the same beneficial effects may also be achieved.

The method provided by the embodiment of the present invention is illustrated below with reference to the logical channel corresponding to the first service bearer as a specific logical channel:

example 1:

a network side:

step 1: the network side equipment assigns a logical channel (logical channel 1) to the terminal and configures a token bucket suspension indication. The indication may be configured for a DRB, or configured for a PDCP layer corresponding to the DRB, or configured for a logical channel corresponding to the DRB. The token bucket suspension indication may be RRC signaling or MAC layer signaling or physical layer signaling.

A terminal side: the terminal decides which priority to use at its discretion. The terminal uses the lowest priority when the data of the logical channel does not reach the transmission time window, so that the data of the logical channel cannot be mapped to the uplink transmission resource when the uplink resource is limited; and when the logical channel data reaches the transmission time window, the terminal performs data mapping and transmission by using the conventional priority.

Example 10:

this embodiment is illustrated by introducing a priority adjustment mechanism, and by the network side device decision:
