Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present application more apparent, the following detailed description will be given with reference to the accompanying drawings and the specific embodiments.

Aiming at the problem that the current buffer status reporting scheme causes that important data packets cannot be transmitted in time, the application provides an information transmission method, which is applied to a terminal, as shown in fig. 1, and comprises the following steps:

step 11: and sending a BSR (Buffer Status Report ) carrying first indication information to the network equipment under the condition that the first type data packet is determined to be received and the current uplink resource does not support transmission of the first type data packet.

In this embodiment, the first type of data packet may be a data packet with a importance level greater than a third threshold value; the first indication information is used for indicating that a first logic channel group has the first type data packet to wait for transmission; the first logical channel group is a logical channel group corresponding to the first type data packet.

Wherein "first type data packets" may be understood as important data packets; the "first indication information" may be understood as indicating that the logical channel group corresponding to the important data packet has an important data packet waiting for transmission.

According to the information transmission method provided by the embodiment of the invention, under the condition that the first type data packet is received and the current uplink resource does not support transmission of the first type data packet, a Buffer Status Report (BSR) carrying first indication information is sent to the network equipment, wherein the first indication information is used for indicating that a first logic channel group exists, the first type data packet waits for transmission, and the first logic channel group is a logic channel group corresponding to the first type data packet, so that the purpose of adding an important data packet indication during BSR reporting can be achieved by means of the BSR carrying the first indication information, the timely transmission of the important data packet is ensured, and user experience is ensured.

In this embodiment, the important data packet received by the terminal may be selected as the high-layer data. Before the above-mentioned sending the buffer status report BSR carrying the first indication information to the network device, the terminal may execute a first operation to determine that the first type data packet is received; specifically, the performing the first operation determines that the first type of data packet is received, including any one of the following (i.e., the terminal may determine that the important data packet is received in any one of the following manners):

1) When the high-level data arrives at an AS (Access Stratum) of the terminal and the AS receives second indication information sent by a high level, determining the received high-level data AS a first type data packet; wherein the second indication information is used for indicating that the high-level data is the first type data;

2) And determining the received high-level data as the first type data packet according to the pre-agreed data packet belonging to the first type data packet.

Thus, the first type data packet can be flexibly and accurately determined.

Optionally, the first type of data packet may include at least one of the following:

a pre-agreed data packet;

a data packet corresponding to the I frame;

time-lapse tight packets.

Thus, timely transmission of various important data packets can be ensured as much as possible. Wherein "last at least one data packet" comprises: the last 1 (relatively important because the last packet is typically sent the latest, the delay budget is the shortest) or the last few; the last 1 means the last 1 of the sequences, and the last few means the ones obtained by dividing the sequences in reverse order from the last 1. I frames are key frames, belonging to intra-frame compression. The "latency-critical packets" may include: packets with a latency below the second threshold.

In the embodiment of the application, the terminal may use the newly defined MAC CE to perform the important packet indication, and design the MAC CE based on the BSR type. Optionally, the manner of sending the BSR may be: the terminal transmits a BSR carrying first indication information to the network device using the first medium access control unit MAC (Medium Access Control) CE (Control Element). Wherein, in case the BSR is a short BSR or a truncated short BSR, the first MAC CE may be provided with: a logical channel group identification indication field, a first indication field, and a first buffer size indication field; the logic channel group identification indication field is used for indicating a target logic channel group identification, the first indication field is used for indicating whether the first type data packet waits for transmission or not, and the first buffer size indication field is used for indicating the buffer size corresponding to the logic channel group corresponding to the target logic channel group identification; alternatively, in the case where the BSR is a long BSR or a truncated long BSR, the first MAC CE may be provided with: a logical channel group indication field, a second indication field, and a second buffer size indication field; the logic channel group indication field is used for indicating whether the logic channel group has uplink data to wait for transmission, the second indication field is used for indicating whether the corresponding logic channel group has the first type data packet to wait for transmission, and the second buffer size indication field is used for indicating the buffer size corresponding to the logic channel group with the uplink data to wait for transmission.

Thus, the related indication of the BSR to the important data packet can be better realized so as to ensure the timely transmission of the important data packet as much as possible. The buffer size of the logical channel group having the important data packet to be transmitted may be preferentially transmitted in the "second buffer size indication field".

In the embodiment of the present application, a first operation may be performed under a condition that it is determined that there is a logical channel or a logical channel group that needs to transmit the first type data packet, and it is determined that the first type data packet is received; correspondingly, the executing the first operation, determining that the first type of data packet is received includes: executing a first operation under the condition that the first condition is met, and determining that a first type data packet is received; wherein the meeting the first condition includes any one of the following (i.e., the terminal may determine that there is a logical channel or a logical channel group that needs to transmit the first type of data packet in any one of the following manners):

1) Determining that a logic channel or a logic channel group needing to transmit the first type data packet exists in a preset or preconfigured mode;

2) A network configuration mode; specifically, the terminal receives first configuration information (the first configuration information is logic channel configuration information or logic channel group configuration information) sent by the network device, wherein the first configuration information is provided with a parameter field for whether the first type data packet needs to be transmitted, and determines that a logic channel or logic channel group for which the first type data packet needs to be transmitted exists according to the first configuration information.

Thus, various logic channels or logic channel groups which are determined to be required for transmitting important data packets can be realized. In addition, the important data packet may be always transmitted, and the important data packet is not distinguished in the prior art, and the purpose of the "parameter field" set in the present scheme may indicate whether the terminal AS needs to distinguish the first type of data packet (corresponding to the important data packet). A parameter field may correspond to a type of data packet included in the first type of data packet, but is not limited thereto.

The embodiment of the application also provides an information transmission method, which is applied to the network equipment, as shown in fig. 2, and comprises the following steps:

step 21: and receiving a Buffer Status Report (BSR) carrying first indication information sent by the terminal.

In this embodiment, the first indication information is used to indicate that a first type of data packet exists in the first logical channel group to wait for transmission; the first logical channel group is a logical channel group corresponding to the first type data packet; the first type of data packet may be a data packet having a significance level greater than a third threshold.

According to the information transmission method, the Buffer Status Report (BSR) carrying the first indication information is sent by the receiving terminal; the first indication information is used for indicating that a first logic channel group has a first type of data packet to wait for transmission; the first logical channel group is a logical channel group corresponding to the first type data packet; the BSR carrying the first indication information can be supported to achieve the purpose of adding the indication of the important data packet when the BSR reports, so that the timely transmission of the important data packet is ensured, and the user experience is ensured.

In this embodiment, the network device may agree with the terminal in advance which are important packets. Before the receiving terminal sends the buffer status report BSR carrying the first indication information, the network device may pre-agree with the terminal on a data packet belonging to the first type of data packet. This allows an accurate determination of the first type of data packet.

Optionally, the first type of data packet may include at least one of:

a pre-agreed data packet;

a data packet corresponding to the I frame;

time-lapse tight packets.

Thus, timely transmission of various important data packets can be ensured as much as possible.

In the embodiment of the application, the network device may receive an important data packet indication transmitted by the terminal using the newly defined MAC CE, and the terminal may design the MAC CE based on the BSR type. Optionally, the manner of receiving the BSR may be:

the network equipment receives a BSR carrying first indication information sent by the terminal by using the first MAC CE. Wherein, in case the BSR is a short BSR or a truncated short BSR, the first MAC CE may be provided with: a logical channel group identification indication field, a first indication field, and a first buffer size indication field; the logic channel group identification indication field is used for indicating a target logic channel group identification, the first indication field is used for indicating whether the first type data packet waits for transmission or not, and the first buffer size indication field is used for indicating the buffer size corresponding to the logic channel group corresponding to the target logic channel group identification; alternatively, in the case where the BSR is a long BSR or a truncated long BSR, the first MAC CE may be provided with: a logical channel group indication field, a second indication field, and a second buffer size indication field; the logic channel group indication field is used for indicating whether the logic channel group has uplink data to wait for transmission, the second indication field is used for indicating whether the corresponding logic channel group has the first type data packet to wait for transmission, and the second buffer size indication field is used for indicating the buffer size corresponding to the logic channel group with the uplink data to wait for transmission.

In this embodiment of the present application, the network device may determine, by using a pre-agreed or pre-configured manner, a logical channel or a logical channel group to be transmitted for the first type of data packet together with the terminal; the terminal can also determine a logic channel or a logic channel group which needs to transmit the first type data packet through a network configuration mode; specifically, before receiving the buffer status report BSR carrying the first indication information sent by the terminal, the information transmission method further includes: determining a logic channel or a logic channel group which needs to transmit the first type data packet in a pre-agreed or pre-configured mode; or sending first configuration information to the terminal, wherein the first configuration information is logic channel configuration information or logic channel group configuration information; the first configuration information is provided with a parameter field for transmitting the first type data packet.

Thus, the logic channel for realizing diversified determination of important data packets to be transmitted can be supported.

In this embodiment of the present application, after receiving a buffer status report BSR carrying first indication information sent by a terminal, the information transmission method further includes: and according to the BSR, scheduling resources for the first logic channel group preferentially.

Thus, the priority transmission (timely transmission) of the important data packet can be directly realized. The "scheduling resources preferentially for the first logical channel group" can be understood as: scheduling a ranking order of resources for the first logical channel group in advance.

The following illustrates an information transmission method provided in the embodiments of the present application, where a base station is taken as an example of a network device, and an application layer is taken as an example of a higher layer.

Considering that the scheme supports the terminal to report the buffer status to assist the base station in uplink data resource scheduling, the buffer status can be reported in granularity of a logical channel group, and the base station can pre-configure which logical channels belong to one logical channel group. Embodiments of the present application may specifically relate to the following:

1. when the terminal application layer data arrives at the terminal AS (access layer), for some important application layer data, the application layer may inform the AS that the corresponding data packet is an important data packet (corresponding to the first type of data packet described above).

The important data packet may be at least one last data packet obtained after the segmentation of a certain application layer data frame, a data packet corresponding to a request message initiated by the terminal application layer to the network side application server, a data packet corresponding to an application layer data stream with a higher priority (corresponding to the priority higher than a first threshold), or a data packet corresponding to an application layer data stream (corresponding to the first higher layer data stream) which needs to be synchronized with other application layer data streams but has a relatively slow progress. The important data packet may be a data packet predetermined by the base station, a data packet corresponding to an I frame, or a data packet having a short delay.

2. After knowing that the corresponding data packet is an important data packet, if the current uplink resource scheduled for the terminal cannot transmit the important data packet (i.e. the current uplink resource is not supported), the terminal can trigger reporting of a Buffer Status Report (BSR); the base station is informed of the priority of scheduling resources for the logical channel group on which the important data packet is reported mainly by indicating that the logical channel group corresponding to the important data packet has the important data packet waiting for transmission (corresponding to the above-mentioned BSR which is sent and carries the first indication information).

3. The specific method of the indication may be to define a new BSR MAC CE (BSR medium access control element, corresponding to the first MAC CE described above), and add an important packet indication based on the logical channel group.

4. Correspondingly, the base station can inform the terminal of which logical channels or logical channel groups need to report important data packets (corresponding to the first configuration information sent to the terminal) when the configuration of the logical channels and the logical channel groups is sent to the terminal; or informing the terminal which logical channels or logical channel groups need to report the important data packet by means of advance provisioning or configuration (corresponding to the above-mentioned method of provisioning or configuration in advance, determining that there are logical channels or logical channel groups needing to transmit the first type of data packet).

Specifically, one possible configuration mode is: adding relevant fields in the logical channel configuration (LogicalchannelConfig), such as at least one of the fields LogicalchannelBSR-LastPacketApplied (logical channel BSR-last packet application), logicalchannelBSR-RequestPacketApplied (logical channel BSR-request packet application), logicalchannelBSR-vit 5QIApplied (logical channel BSR-Vital5QI application), logicalchannelBSR-Sync5QIApplied, and LogicalchannelBSR-importantPacketApplied (logical channel BSR-Vital packet application); wherein:

If the logicalChannelBSR-LastPacketApplied is set to true, the logic channel is indicated to report the BSR preferentially if the uplink data packet received from the application layer corresponds to the last at least one data packet obtained after the segmentation of the application layer data frame; if the logicalChannelBSR-RequestPacketApplied is set to true, the logic channel is indicated to report the BSR preferentially if the corresponding logic channel receives the request message of the application layer corresponding to the uplink data packet from the application layer; if the logicalChannelBSR-Vital5QIApplied is set to true, the corresponding logical channel is indicated to report the BSR preferentially if the uplink data packet received from the application layer comes from a data stream with higher priority (indicating a scalar pointing to the quality of service (QoS) characteristic of 5G); if the logicalChannelBSR-Sync5QIApplied is set to true, the corresponding logical channel is indicated to report the BSR preferentially if the uplink data packet received from the application layer comes from an application layer data stream which needs to be synchronized with other application layer data streams but has a relatively slow progress.

In addition, in this solution, whether the BSR needs to be preferentially reported when there is an uplink important data packet may also be indicated only in RRC (Radio Resource Control ) signaling configuration (i.e., logicalChannelConfig transmitted by RRC), specifically: when the logicalChannelBSR-important packet applied is set to true, it means that if the uplink packet received from the application layer is an important packet, the BSR is preferentially reported. Wherein authentication of important data packets can be kept consistent by a predefined between the base station and the terminal (corresponding to the previously agreed data packets described above).

5. After receiving the signaling configuration (i.e. logicalChannelConfig), the terminal subsequently reports important data packets to the base station by using a new BSR MAC CE (corresponding to the first MAC CE) aiming at the situation that some BSR needs to be reported to the base station (wherein, an important data packet indication is added when the important data packets are reported to the BSR).

Specifically, one possible new BSR MAC CE design may be as shown in fig. 3 and 4:

wherein, fig. 3 is a new Short or Truncated Short BSR design, and fig. 4 is a new Long or Truncated Long BSR design.

For a short BSR or truncated short BSR, in fig. 3, the LCG ID field (corresponding to the logical channel group identity indication field) is a logical channel group identity (assuming that at most 8 logical channel groups are configured for one terminal); the IP field is an indication (corresponding to the first indication field) of whether there is an important data packet to be transmitted; buffer Size field (corresponding to the first Buffer Size indication field) is a range of uplink data Size to be transmitted for this logical channel group (here, to ensure that the short BSR is controlled to be one byte), a Buffer Size of 4 bits is assumed, that is, only 16 ranges can be indicated, but the present scheme does not limit the number of bits of Buffer Size.

For long BSR or truncated long BSR, in fig. 4, LCG ₀ To LCG ₇ The field is bitmap (bit map) indicating whether each logical channel group has uplink data to be transmitted (pair ofA logical channel group indication field as described above); IP (Internet protocol) ₀ To IP ₇ The domain is an indication (corresponding to the second indication domain) of whether each logic channel group has an important data packet to be transmitted; the Buffer Size 1-m field represents the uplink data Size range (corresponding to the second Buffer Size indication field) corresponding to the logical channel group having data to be transmitted, and may preferentially transmit the Buffer Size of the logical channel group having important data packets to be transmitted.

As can be seen from the above, the scheme provided by the embodiment of the application adds the important data packet indication when the BSR reports, so that the priority transmission of the important data packet corresponding to the application layer data frame is ensured, and the user experience is ensured; namely, an important data packet indication is added in the BSR to ensure the timely transmission of the important data packet.

The embodiment of the application also provides an information transmission device, which is applied to a terminal, as shown in fig. 5, and includes:
