Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating an information sending method according to an embodiment of the present invention. The information transmission method is applied to a terminal side.
As shown in fig. 1, the information transmitting method includes: a Buffer Status Report (BSR) is sent during the measurement interval.
Wherein, the terminal specifies the uplink traffic type of the BSR transmitted during the measurement interval according to the network side configuration or protocol.
As an example, receiving configuration information, the configuration information being used to indicate an uplink traffic type capable of transmitting a BSR during a measurement interval; and according to the uplink service type, transmitting the BSR corresponding to the uplink service during the measurement interval. For example, the configuration information indicates that the BSR of the URLLC service is transmitted during the measurement interval, and the terminal transmits the BSR of the URLLC service during the measurement interval according to the configuration information. The BSR transmitted during the measurement interval includes a combination of one or more of: a BSR triggered by a Logical Channel (LCH) where the uplink service is located, a BSR triggered by a Logical Channel Group (LCG) where the uplink service is located, and a Regular (Regular) BSR.
As another example, the BSR corresponding to the uplink traffic is transmitted during the measurement interval according to the uplink traffic type specified by the protocol. I.e. the protocol specifies the uplink traffic type corresponding to the uplink data that can be transmitted during the measurement interval.
If the Buffer Status (BS) value of the LCH in which the uplink service is located is greater than a threshold, the BSR is sent during the measurement interval. The threshold value may be 0 or a value other than 0.
And if the BS value of the LCH where the uplink service is located is greater than 0, transmitting the BSR during the measurement interval.
And if the BS value of the LCG where the uplink service is located is larger than a threshold value, transmitting the BSR during the measurement interval. The threshold value may be 0 or a value other than 0.
And if the BS value of the LCG where the uplink service is located is greater than 0, transmitting the BSR during the measurement interval.
The uplink traffic in the above includes one or more of the following types: Ultra-Reliable and Low Latency Communications (URLLC) traffic, traffic scheduled by Modulation and Coding Scheme Cell Radio network temporary Identifier (MCS-C-RNTI), traffic identified by a specific Downlink Control Information (DCI) format (format), and other traffic identified as a representation of URLLC traffic.
It should be noted that the configuration of the measurement interval includes the following:
mode 1, 1 independent measurement interval is configured for 1 terminal;
mode 2, configuring independent measurement intervals corresponding to low Frequency (Frequency Range 1, FR1) or high Frequency (Frequency Range 2, FR 2);
mode 3, 1 serving cell has independent measurement interval;
mode 4, 1 Medium Access Control (MAC) entity has 1 independent measurement interval.
The information of the measurement interval includes:
1. a measurement interval repetition period, for example, the period is 40 ms;
2. the measurement interval duration, for example, the length of time for the terminal to measure in 1 cycle is 6 ms;
3. for example, the duration of the measurement interval starts from Slot-1(Slot corresponds to Chinese is a time Slot) of SFN-1 (the Chinese corresponding to SFN is a System Frame Number, and English is a System Frame Number), and repeats with a period of 40ms, and the Slot-1 of SFN-1 is the "start time position of the measurement interval".
It should be noted that the role of transmitting the BSR is to inform the base station of the amount of data that the terminal needs to transmit. The transmission of a BSR will be triggered when the following events occur:
1. when all the logical channels of all the LCGs have no uplink data that can be sent, if any one of the logical channels belonging to any one of the LCGs has data that can be sent, the terminal triggers BSR reporting, for example: the terminal transmits uplink data for the first time. This BSR is referred to as Regular BSR.
2. High priority data arrival: if the terminal has sent a BSR and is waiting for an Uplink grant (UL grant), and there is data with higher priority to be transmitted at this time, the terminal triggers BSR reporting, and the BSR is called a Regular BSR.
3. The terminal periodically updates the base station with its own buffer status, which is called Periodic BSR (Periodic BSR).
4. The base station configures a retransmission timer (timer) for the terminal, and when the timer is over time and data in any logical channel of any LCG of the terminal can be sent, the BSR is triggered. This BSR is referred to as Regular BSR.
5. When the terminal has uplink resources and finds that data to be transmitted is not enough to fill the resources, if an excess padding bit (padding bit) is equal to or larger than the size of the subheader corresponding to the BSR MAC control element +, the excess bit is used to transmit the BSR. This BSR is called Padding BSR.
Wherein, the trigger (trigger) of the BSR has a cancellation mechanism, and if the UL grant allocated to the terminal can load all data and the UL grant cannot additionally load the BSR and the subheader of the BSR, the BSR is cancelled.
Each logical Channel is placed in an LCG, the terminal reports the BSR based on the LCG, and the BSR reports the BSR through a BSRMAC Control unit (Control Element) of the MAC layer, and finally sends the BSR to the network side through a Physical Uplink Shared Channel (PUSCH).
In the embodiment of the invention, the performance of uplink service during the measurement interval can be ensured by sending the BSR during the measurement interval. Further, if the BSR corresponding to the high-priority service is sent in the corresponding serving cell, the performance of the high-priority service can be ensured.
Fig. 2 shows a flow chart of an information transmitting method according to another embodiment of the present invention. The information transmission method is applied to a terminal side.
As shown in fig. 2, the information transmitting method includes:
s101, judging whether a BSR to be sent meeting a preset condition exists or not, if so, executing S102, and if not, executing S103.
Wherein the BSR satisfying the predetermined condition comprises a combination of one or more of: a BSR triggered by an LCH where the uplink service is located, a BSR triggered by an LCG where the uplink service is located, and a Regular (Regular) BSR. The uplink service may be one or more of the following services: a URLLC service, a service scheduled by MCS-C-RNTI, a service identified by a specific Downlink Control Information (DCI) format (format), and a service represented by another representation identified as a URLLC service.
And if the scheduling transmission of the BSR conflicts with the measurement interval, judging whether the BSR to be sent meeting the preset condition exists. The collision of the scheduled transmission of the BSR with the measurement interval includes: the time period of the scheduling transmission resource of the BSR partially overlaps the measurement interval, or the time period of the scheduling transmission resource of the BSR completely overlaps the measurement interval.
The decision time point can be divided into the following cases:
1. the point in time of the decision may be determined by the terminal.
2. The point in time of the decision is not later than the point in time of the transmission of the BSR.
3. The time point of the decision is not later than a first time point, wherein the first time point is earlier than the time point of transmitting the BSR, and a time interval between the first time point and the time point of transmitting the BSR is a time required for the radio frequency transition.
4. The determined time point is not later than a second time point, wherein the second time point is earlier than the time point of transmitting the BSR, and a time interval between the second time point and the time point of transmitting the BSR is a physical layer uplink shared channel processing time (pushprocessing time).
5. The point in time of the decision is not later than a third point in time, wherein the third point in time is earlier than the point in time of transmitting the BSR, and the time interval between the third point in time and the point in time of transmitting the BSR is the time required for the higher layer to assemble the packet.
6. The time point of the decision is not later than a fourth time point, wherein the fourth time point is earlier than the time point of transmitting the BSR, and a time interval between the fourth time point and the time point of transmitting the BSR is a sum of a time required for radio frequency conversion (RF returning) and a time required for higher layer assembly of the packet.
7. The time point of the decision is not later than a fifth time point, wherein the fifth time point is earlier than the time point of transmitting the BSR, and a time interval between the fifth time point and the time point of transmitting the BSR is the sum of the PUSCH processing time and the time required by the higher layer to assemble the packet.
8. The time point of the decision is not later than a sixth time point, wherein the sixth time point is earlier than the time point of transmitting the BSR, and a time interval between the sixth time point and the time point of transmitting the BSR is a sum of a time required for the radio frequency switching and a PUSCH processing time.
9. The time point of the decision is not later than a seventh time point, wherein the seventh time point is earlier than the time point of transmitting the BSR, and a time interval between the seventh time point and the time point of transmitting the BSR is a sum of a PUSCH processing time, a time required for higher layer assembly of the packet, and a time required for radio frequency conversion.
Optionally, the time required for radio frequency conversion is greater than the PUSCH processing time.
S102, ignoring the measurement interval to transmit the BSR satisfying a predetermined condition during the measurement interval.
There are three ways to ignore the measurement interval:
in the first mode, the duration of the whole measurement interval is ignored.
If the length from the time point when the BSR is transmitted to the ignored cut-off point of the measurement interval is less than or equal to a threshold value, the duration of the whole measurement interval is ignored.
The second way, the time duration required for transmission of the BSR during the measurement interval is ignored. I.e. ignoring part of the duration of the measurement interval, the measurement is performed during a non-ignored duration of the measurement interval.
And thirdly, ignoring the time length from the ignored measurement interval starting point to the BSR end time point during the measurement interval.
If the MAC entity of the terminal receives the scheduling information, wherein the transmission resource corresponding to the scheduling information is in the measuring interval period; a MAC PDU (Protocol Data Unit in english and Protocol Data Unit in chinese) is generated according to the scheduling information to transmit a BSR during the measurement interval. The scheduling information includes information for dynamic scheduling or information for semi-persistent scheduling. The scheduling information includes a combination of one or more of: scheduling information for a terminal, scheduling information for a MAC entity, scheduling information for an uplink service. The uplink service may be one or more of the following services: URLLC traffic, traffic scheduled by MCS-C-RNTI, traffic identified by a specific DCI format, other traffic identified as representation of URLLC traffic.
S103, no BSR is transmitted during the measurement interval to perform measurement during the measurement interval.
For the following three cases, the MAC entity should not generate a MAC PDU, thereby causing no BSR to be sent during the measurement interval.
In the first case:
the MAC entity does not receive the scheduling information, and the transmission resource corresponding to the scheduling information is positioned in the measuring interval period; the scheduling information may be dynamic scheduling or semi-persistent scheduling; the scheduling information may be for a terminal or a MAC entity or an uplink service, which may be one or more of the following services: URLLC traffic, traffic scheduled by MCS-C-RNTI, traffic identified by a specific DCI format, other traffic identifiable as representation of URLLC traffic.
In the second case:
at the determined time point, no BSR of the uplink traffic is to be transmitted, where the BSR includes a combination of one or more of the following: a BSR triggered by an LCH where the uplink service is located, a BSR triggered by an LCG where the uplink service is located, and a conventional BSR. Or when reporting the BSR, the BS value of the LCH or LCG in which the uplink service is located is greater than a threshold. The uplink service may be one or more of the following services: URLLC service, MCS-C-RNTI service, DCI format identified service, and other services which can be identified as represented by URLLC service representation mode.
Or, if there is no dynamic scheduling resource or semi-persistent scheduling resource configured during the measurement interval, the BSR is not transmitted during the measurement interval, and the measurement is performed during the measurement interval.
In the third case:
if no configuration ignores uplink dynamic scheduling (skipperlinkdynamic) and there is no BSR of the uplink traffic to be sent at the determined time point, no BSR is sent during the measurement interval, so as to perform measurement during the measurement interval. Or, if no configuration ignores uplink Semi-Persistent Scheduling (skiupplinksps), and there is no BSR of the uplink traffic to be transmitted at the decided time point, the BSR is not transmitted during the measurement interval to perform measurement during the measurement interval.
The BS value of LCH or LCG where the uplink service is located is larger than a threshold value. The uplink service may be one or more of the following services: URLLC service, MCS-C-RNTI service, DCI format identified service, and other services which can be identified as represented by URLLC service representation mode.
Fig. 3 is a flowchart illustrating an information sending method according to another embodiment of the present invention. The information transmission method is applied to a terminal side.
As shown in fig. 3, the information transmitting method includes: a Scheduling Request (SR) is transmitted during the measurement interval.
In the embodiment of the invention, the SR is sent in the measuring interval, so that the performance of the uplink service in the measuring interval can be ensured.
Fig. 4 shows a flow chart of an information transmitting method according to still another embodiment of the present invention. The information transmission method is applied to a terminal side.
As shown in fig. 4, the information transmitting method includes:
s201, determining whether there is an SR to be transmitted, if yes, performing S202, and if no SR to be transmitted is determined, performing S203.
If the scheduling transmission resource of the SR conflicts with the measurement interval, judging whether the SR to be transmitted exists. The collision of the scheduled transmission resource of the SR with the measurement interval includes: the time period of the scheduling transmission resource of the SR partially overlaps the measurement interval, or the time period of the scheduling transmission resource of the SR completely overlaps the measurement interval.
The decision time point can be divided into the following cases:
1. the point in time of the decision may be determined by the terminal.
2. The time point of the decision is not later than the time point of transmitting the SR.
3. The time point of the decision is not later than a first time point, wherein the first time point is earlier than the time point of transmitting the SR, and a time interval between the first time point and the time point of transmitting the SR is a time required for the radio frequency conversion.
4. The determined time point is not later than a second time point, wherein the second time point is earlier than the time point of transmitting the SR, and a time interval between the second time point and the time point of transmitting the SR is a physical layer uplink control channel processing time (pucch processing time).
5. The decision point in time is no later than a third point in time, wherein the third point in time is earlier than the point in time at which the SR is transmitted, and a time interval between the third point in time and the point in time at which the SR is transmitted is a time required for a higher layer to assemble a packet.
6. The decision point in time is no later than a fourth point in time, wherein the fourth point in time is earlier than the point in time when the SR is transmitted, and a time interval between the fourth point in time and the point in time when the SR is transmitted is a sum of a time required for radio frequency conversion (RF retransmission) and a time required for a higher layer to assemble a packet.
7. The decision time point is not later than a fifth time point, wherein the fifth time point is earlier than the time point of transmitting the SR, and a time interval between the fifth time point and the time point of transmitting the SR is a sum of a PUCCH processing time and a time required for a higher layer to assemble the data packet.

9. The decision time point is not later than a seventh time point, wherein the seventh time point is earlier than the time point of transmitting the SR, and a time interval between the seventh time point and the time point of transmitting the SR is a sum of a PUCCH processing time, a time required for a higher layer to assemble a data packet, and a time required for radio frequency conversion.
Optionally, the time required for radio frequency conversion is greater than the PUCCH processing time.
S202, the measurement interval is ignored to transmit the SR during the measurement interval.
There are three ways to ignore the measurement interval:
in the first mode, the duration of the whole measurement interval is ignored.
For example, if the length from the transmission SR ending time point to the ignored measurement interval cutoff point is less than or equal to the threshold value, the duration of the entire measurement interval is ignored.
The second way, the time duration required for transmitting the SR during the measurement interval is ignored. I.e. ignoring part of the duration of the measurement interval, the measurement is performed during a non-ignored duration of the measurement interval.
And thirdly, neglecting the time length from the neglected starting point of the measurement interval to the end time point of the SR transmission in the measurement interval.

As another example, uplink data corresponding to the uplink traffic is transmitted during the measurement interval according to the type of the uplink traffic specified by the protocol. I.e. the protocol specifies the uplink traffic type corresponding to the uplink data that can be transmitted during the measurement interval.
It should be noted that the configuration of the measurement interval includes the following:
