Description

Information transmission method and device

The present application claims priority of chinese patent application having application number 201910655206.0 entitled "information transmission method and apparatus" filed by chinese patent office on 19/7/2019, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.

Background

In the 5G new radio technology (NR), release 16(Rel-16) terminals will support simultaneous transmission of different traffic types. There is a problem that, when channels of different service types overlap, because of the high requirement of Ultra-Reliable Low-Latency Communication (URLLC) service on Latency in Rel-16, if the timeline requirement must be satisfied between channels that still overlap according to the rules of Rel-15, the requirement of URLLC on Latency may not be satisfied in some cases. For example, as shown in fig. 1, it is assumed that there is an overlap between Enhanced Mobile Broadband (eMBB) Scheduling Request (SR) and Physical Uplink Control Channel (PUCCH) resources of URLLC hybrid automatic repeat Request acknowledgement (HARQ-ACK), and PUCCH resources of SR precede PUCCH resources of HARQ-ACK. Processing time delays T1 and T2 are satisfied between the end position of Downlink Control Information (DCI) and a Physical Downlink Shared Channel (PDSCH) and the starting position of PUCCH resources of corresponding HARQ-ACK, but the condition is not allowed in Rel-15 because the processing time delays T1 and T2 are not satisfied between the end positions of the DCI and the PDSCH and the starting position of the PUCCH resources of SR, that is, according to the provision of Rel-15, the corresponding HARQ-ACK of the PDSCH needs to be transmitted after the end position of the SR resources, collision with the SR resources is avoided, and the feedback time delay of the URLLC service is increased due to the fact that the PDSCH transmits the URLLC service.

In the NR Rel-15 stage, simultaneous transmission of uplink channels or signals is not supported, so when resources of the uplink channels or signals overlap, a specific transmission rule for multiplexing or discarding information needs to be defined, so that the terminal only transmits one uplink channel or signal at the same time. Since some of the channels or signals need to be discarded when the resources of the uplink channels or signals overlap, many terminal equipment manufacturers do not want to find that the channels need to be discarded when half of the resources are found in the process that the terminal prepares to transmit an uplink channel. Thus defining timeline requirements for uplink channel collisions. When the resources of the uplink channels are overlapped, the terminal may multiplex and transmit the uplink information carried by the overlapped channels under the condition that the timeline requirement is met.

Rel-15 requires the following details for the time line of the uplink channel overlap:

when the resources of PUCCH and PUCCH/PUSCH are overlapped in one slot, if one PUCCH or PUSCH correspondingly has DCI scheduling, then:

when the overlapped channel includes a PUCCH carrying HARQ-ACK, a time interval between a start time of an earliest transmission channel in the overlapped channel and an end position of any one PDSCH corresponding to the PUCCH or DCI indicating Semi-Persistent Scheduling (SPS) release needs to be greater than a value predefined in the standard; when a PUSCH is included in an overlapped channel or when a PUCCH carrying HARQ-ACK and a PUCCH carrying CSI/SR are included in the overlapped channel, a time interval between a start time of an earliest transmission channel in the overlapped channel and an end position of scheduling a PUSCH and scheduling a PDSCH and DCI indicating SPS release needs to be greater than a value predefined in the standard;

when the resources of the PUCCH and PUCCH/PUSCH are overlapped in one slot, if all PUCCH and PUSCH have no corresponding scheduling DCI, then:

when the overlapped channel contains a PUCCH carrying SPS HARQ-ACK, in order to ensure that PDSCH demodulation and PUCCH preparation are completed before the HARQ-ACK is transmitted, a time interval between the starting time of an earliest transmission channel in the overlapped channel and the end position of the SPS PDSCH is required to be more than a value predefined in a standard;

when the overlapped channel does not contain the PUCCH carrying SPS HARQ-ACK, namely, when the PUCCH resources carrying CSI and SR are overlapped, or the PUSCH without DCI scheduling is overlapped with the PUCCH resources carrying CSI and/or SR transmission, time line judgment is not needed.

In the Rel-15 stage, different service types are not distinguished in the system, when there is overlap between uplink channels, all the overlapping channels must meet the timeline requirement, and the UE does not expect that the overlapping condition which does not meet the timeline requirement can occur. Therefore, when the uplink channels overlap, the UE may multiplex and transmit corresponding uplink information according to a predetermined rule.

Specifically, when a PUCCH carrying CSI/SR overlaps with one PUCCH carrying HARQ-ACK, multiplexing transmission is performed according to the following multiplexing transmission rule:

when the PUCCH bearing the SR is overlapped with the PUCCH format 0 bearing the HARQ-ACK, the SR and the HARQ-ACK are transmitted through PUCCH resource multiplexing of the HARQ-ACK; when PUCCH format 0 bearing SR is overlapped with PUCCH format 1 bearing HARQ-ACK, the SR is discarded; when PUCCH format 1 bearing SR is overlapped with PUCCH format 1 bearing HARQ-ACK, HARQ-ACK is transmitted on PUCCH resource of SR in positive SR, and HARQ-ACK is transmitted on PUCCH resource of HARQ-ACK in negative SR; when the PUCCH carrying SR overlaps PUCCH format 2/3/4 carrying HARQ-ACK, both SR (including positive and negative SR) and HARQ-ACK are put on HARQ-ACK resources for transmission;

when the PUCCH carrying SPS HARQ-ACK (namely HARQ-ACK corresponding to SPS PDSCH) is overlapped with the PUCCH carrying CSI, the SPS HARQ-ACK is transferred to PUCCH resources corresponding to the CSI for multiplexing transmission with the CSI. When a PUCCH carrying dynamic HARQ-ACK (namely the HARQ-ACK corresponding to the PDSCH with the corresponding DCI scheduling) is overlapped with a PUCCH carrying CSI, selecting one set from the configured PUCCH resource sets according to the bit numbers of the HARQ-ACK and the CSI, and then determining one PUCCH resource from the selected set according to a PUCCH resource indication domain in the DCI for scheduling the PDSCH, wherein the PUCCH resource is used for simultaneously carrying the HARQ-ACK and the CSI;

and when the PUCCH carrying the SR is overlapped with the PUCCH carrying the CSI, transferring the SR to PUCCH resources corresponding to the CSI for multiplexing transmission with the CSI.

When a PUCCH carrying the HARQ-ACK/CSI/SR is overlapped with a PUSCH carrying the PUSCH which does not contain Aperiodic Channel State Information (A-CSI), the HARQ-ACK/CSI/SR is transferred to a PUSCH resource to be transmitted with data multiplexing. And when the PUCCH carrying the HARQ-ACK/CSI/SR is overlapped with the PUSCH carrying the A-CSI, transferring the HARQ-ACK/SR to PUSCH resources for multiplexing transmission with data, and discarding the CSI. When a PUCCH carrying an SR overlaps a PUSCH carrying only A-CSI or Semi-Persistent Channel State Information (SP-CSI), the SR is discarded, and only the PUSCH is transmitted.

In the NR Rel-16 stage, the traffic types will be distinguished in the system, and for the channel scheduled by the DCI, the corresponding traffic types may be distinguished through the DCI, for example, the traffic types corresponding to the DCI are distinguished through a newly added bit in the DCI or through a Radio Network Temporary Identity (RNTI) that scrambles the DCI or through a search space in which the DCI is located. For the configured uplink channel, it is possible to determine the corresponding service type through the configuration information. In Rel-16, a terminal may transmit eMBB and URLLC services at the same time, so there may be a situation of resource overlap between channels of different service types.

In summary, in Rel-16, when the channel resources of different service types overlap, if the timeline requirement must be satisfied between the channels with overlapping resources according to the specification of Rel-15, the transmission delay of URLLC service will be increased.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.

In the embodiment of the application, when channels of different service types are overlapped, information corresponding to the service type with higher priority is transmitted, and information corresponding to the service type with lower priority is discarded.

The channel resources of different traffic types overlap, for example, the following cases are included:

a PUCCH carrying eMBB service (such as HARQ-ACK/SR/Channel State Indication (CSI)) and a PUCCH resource carrying URLLC service (such as HARQ-ACK/SR/CSI) are overlapped;

PUCCH carrying eMBB service (such as HARQ-ACK/SR/CSI) and PUSCH resource carrying URLLC service are overlapped;

the PUCCH resource carrying URLLC traffic (e.g., HARQ-ACK/SR/CSI) and the PUSCH resource carrying eMBB traffic overlap.

Optionally, the service type with the higher priority is a URLLC service, and the service type with the lower priority is an eMBB service.

Optionally, the method further includes, before transmission, determining whether to support multiplexing transmission of information of different service types based on high-level signaling configuration, and if the high-level signaling configuration does not support multiplexing transmission between different services, transmitting information corresponding to a service type with a higher priority, and discarding information corresponding to a service type with a lower priority. If the high-level signaling configuration supports multiplexing transmission among different services, multiplexing transmission is carried out on the information of different service types. Or, if the high-level signaling configuration supports multiplexing transmission among different services and meets preset conditions, multiplexing transmission is performed on information of different service types; and when the high-level signaling configuration supports multiplexing transmission among different services but does not meet the preset condition, transmitting information corresponding to the service type with higher priority, and discarding the information corresponding to the service type with lower priority.

The high layer signaling may be information semi-statically configured by the base station through RRC signaling, the UE determines whether to support multiplexing transmission of different service types based on the received high layer signaling, and when the high layer signaling indicates that the information of different service types cannot be multiplexed transmitted, the terminal only sends information of one service type on one PUCCH or PUSCH resource, and may correspond to different kinds of UCI information of the same service type, such as URLLC SR and URLLC HARQ-ACK, but cannot send information of different service types on one PUCCH or PUSCH resource, such as embbb HARQ-ACK and URLLC SR. And if the channels of different service types are overlapped and the high-layer signaling indicates that multiplexing transmission cannot be carried out, discarding the service type with lower priority, for example, discarding the URLLC SR when PUCCH resources of eBB HARQ-ACK and the URLLC SR are overlapped, and only transmitting the eBB HARQ-ACK.

When the higher layer signaling indicates that the information of different service types can be multiplexed for transmission, the terminal may multiplex the overlapped information of different service types, that is, multiplex and transmit the information of different service types on one PUCCH or PUSCH resource, for example, multiplex and transmit eMBB HARQ-ACK and URLLC SR on one PUCCH resource.

Or, when the high layer signaling indicates that the information of different service types can be multiplexed and transmitted, the terminal further needs to further determine whether preset conditions are met, for example, whether timeline requirements and delay requirements are met, if yes, the terminal can perform multiplexing transmission on the overlapped information of different service types, that is, multiplexing transmission of the information of different service types on one PUCCH or PUSCH resource, for example, multiplexing transmission of eMBB HARQ-ACK and URLLC SR on one PUCCH resource; if the priority is not met, the service type with lower priority is discarded, for example, the information of different service types indicated by the high-level signaling can be transmitted in a multiplexing mode, PUCCH resources of eBB HARQ-ACK and URLLC SR are overlapped and meet the time line requirement, SR needs to be transmitted on the PUCCH resources of eBB HARQ-ACK in a multiplexing mode, but the position of the end symbol of the PUCCH resource of the eBB HARQ-ACK is judged to be 5 symbols later than the end position of the PUCCH resource of the URLLC SR, larger time delay is brought to the URLLC service, the preset condition is not met, the URLLC SR is discarded, and only the eBB HARQ-ACK is transmitted.

Optionally, the method further includes determining whether a predefined condition is satisfied before transmission, if so, multiplexing transmission is performed on information of different service types, and if not, information corresponding to a service type with a higher priority is transmitted, and information corresponding to a service type with a lower priority is discarded.

The determining whether the predefined condition is satisfied specifically includes, for example: if the overlapped channels of different service types meet at least one of the following conditions or all the conditions, judging that the overlapped channels meet the predefined conditions, otherwise, judging that the overlapped channels do not meet the predefined conditions:

the overlapping channels meet specified timeline requirements (specific timeline requirements are introduced in the background);

the final transmission channel of the URLLC service meets the specified delay requirement, specifically for example:

the transmission channel finally used for transmitting the URLLC information, which is determined according to the multiplexing transmission rule (specifically, introduced in the background art), is no later than X symbols of the original channel of the URLLC information, where X is an integer greater than or equal to 0;

the final transmission channel of URLLC service meets the specified reliability requirements, specifically for example:

the code rate on the transmission channel finally used for transmitting the URLLC information, determined according to the multiplexing transmission rules, is not higher than a predefined or preconfigured value.

If yes, multiplexing the information of different service types, for example, specifically including;

and when the predefined condition is met, multiplexing and transmitting the information of different service types on the same channel according to the multiplexing transmission rule.

The information corresponding to the service type with the higher transmission priority and the information corresponding to the service type with the lower discarding priority include, for example:

the method comprises the steps of firstly, discarding information of a service type with the lowest priority;

further, if a plurality of overlapped same or different traffic channels exist and meet the time line requirement, multiplexing transmission is carried out according to a multiplexing transmission rule; if different overlapped service channels do not meet the time line requirement, discarding the information of the lowest service type in the overlapped channels, and repeating the current step, namely judging whether the overlapped channels meet the time line requirement or not, and discarding the information of the lowest service type in the overlapped channels under the condition of not meeting the time line requirement until all the overlapped channels meet the time line requirement or until no overlapped channels exist;

or, in the second mode, only the service type information with the highest priority is reserved;

further, if a plurality of overlapped channels of the same service type exist and the time line requirement is met, multiplexing transmission is carried out according to the multiplexing transmission rule.

It should be noted that: when only two service types with different priorities exist, the results obtained by the two modes are the same, namely, the service type with lower priority is discarded, and the service type with higher priority is transmitted, and meanwhile, if the overlapped channels with the same service type priority and meeting the time line requirement exist, multiplexing transmission is carried out according to the multiplexing rule.

Optionally, the method further includes, before determining that the channel resources of different traffic types overlap, if there is channel resource overlap of the same traffic type, preferentially handling channel resource overlap of the same traffic type.

Optionally, the preferentially processing channel resource overlaps of the same traffic types includes: according to the multiplexing transmission rule, the information of the same service type of the overlapped channel (i.e. the channel with overlapped channel resources) is multiplexed and transmitted on the same channel or the information of partial channel is discarded.

An illustration of several specific embodiments is given below.

Example 1:

assuming that there is overlap in time domain between PUCCH resources carrying URLLC HARQ-ACK and PUCCH resources carrying eMBB SR, as shown in fig. 2, it is determined whether a predefined condition is satisfied:

assuming that PUCCH resources carrying URLLC HARQ-ACK are ahead of PUCCH resources carrying eMBSR, the interval between the ending position of DCI corresponding to HARQ-ACK and the starting position of PUCCH carrying HARQ-ACK is larger than T2, and the interval between the ending position of PDSCH corresponding to HARQ-ACK and the starting position of PUCCH carrying HARQ-ACK is larger than T1, thereby determining that the time line requirement is met;

assuming that a PUCCH bearing URLLC HARQ-ACK uses a format 2/3/4, according to a multiplexing transmission rule, SR needs to be transferred to PUCCH resources bearing the URLLC HARQ-ACK to perform combined coding transmission with the HARQ-ACK, so that the resources finally used for transmitting the URLLC HARQ-ACK and the resources originally used for transmitting the URLLC HARQ-ACK are the same PUCCH resources, and the time delay requirement of the URLLC is determined to be met;

assuming that a PUCCH carrying URLLC HARQ-ACK uses a format 2/3/4, according to a multiplexing transmission rule, SR needs to be transferred to PUCCH resources carrying HARQ-ACK for carrying out combined coding transmission with the HARQ-ACK, and if the code rate of SR and HARQ-ACK combined coding does not exceed a predefined value, the reliability requirement is determined to be met.

And the UE determines that the information of different service types can be multiplexed and transmitted because the conditions are met, so that the UE multiplexes and transmits the HARQ-ACK and the SR on PUCCH resources for bearing the HARQ-ACK.

Example 2:

assuming that there is overlap in time domain between PUCCH resources carrying URLLC HARQ-ACK and PUCCH resources carrying eMBB SR, as shown in fig. 3, it is determined whether a predefined condition is satisfied:

assuming that PUCCH resources carrying eMBB SR are ahead of PUCCH resources carrying URLLC HARQ-ACK, the interval between the end position of DCI corresponding to HARQ-ACK and the PUCCH starting position of SR is smaller than T2, and the interval between the end position of PDSCH corresponding to HARQ-ACK and the PUCCH starting position for carrying SR is smaller than T1, therefore, the time line requirement is judged not to be satisfied;

because the time line requirement is not met, the information of different service types can not be subjected to multiplexing transmission, the UE discards the eMBB SR information with lower priority, and only transmits the HARQ-ACK with higher priority.

Example 3:

assuming that there is overlap in time domain between PUCCH resources carrying URLLC SR and PUCCH resources carrying eMBB HARQ-ACK, as shown in fig. 4, it is determined whether a predefined condition is satisfied:

assuming that PUCCH resources carrying URLLC SR are ahead of PUCCH resources carrying eMBB HARQ-ACK, the interval between the end position of DCI corresponding to HARQ-ACK and the PUCCH starting position carrying SR is larger than T2, and the interval between the end position of PDSCH corresponding to HARQ-ACK and the PUCCH starting position carrying SR is larger than T1, so that the time line requirement is determined to be met;

assuming that a PUCCH usage format 2/3/4 carrying eMBB HARQ-ACK is used, according to a multiplexing transmission rule, SR needs to be transferred to PUCCH resources of the HARQ-ACK to perform combined coding transmission with the HARQ-ACK, but the end position of the PUCCH resources of the HARQ-ACK is 3 symbols later than the end position of the SR resources, and assuming that a transmission channel predefined for transmitting URLLC information is not 1 symbol later than an original channel of the URLLC information, the time delay requirement of the URLLC is judged not to be met;

because the time delay requirement of URLLC is not met, the information of different service types can not be subjected to multiplexing transmission, the eMBB HARQ-ACK information with lower priority is discarded by the UE, and only the SR with higher priority is transmitted.

Example 4:

assuming that there is overlap in time domain between PUCCH resources carrying URLLC HARQ-ACK, PUCCH resources carrying URLLC SR, and PUCCH resources carrying eMBB HARQ-ACK, as shown in fig. 5, it is determined whether a predefined condition is satisfied:

supposing that PUCCH resources carrying eMMC HARQ-ACK are ahead of PUCCH resources carrying URLLC SR and PUCCH resources carrying URLLC HARQ-ACK, judging that the time line requirement is not met because the interval between the ending position of DCI corresponding to URLLC HARQ-ACK and the starting position of PUCCH carrying eMMC HARQ-ACK is smaller than T2 and the interval between the ending position of PDSCH corresponding to URLLC HARQ-ACK and the starting position of PUCCH carrying eMMC HARQ-ACK is smaller than T1;

because the time line requirement is not met, the information of different service types can not be subjected to multiplexing transmission, so that the UE discards eMBB HARQ-ACK information with lower priority and only transmits URLLC HARQ-ACK and URLLC SR with higher priority;

furthermore, as the PUCCH resource of URLLC HARQ-ACK and the PUCCH resource of URLLC SR still overlap, the UE needs to first determine whether their resources meet the timeline requirement, and as the PUCCH resource carrying URLLC HARQ-ACK leads the PUCCH resource carrying SR, and the interval between the end position of DCI corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T2, and the interval between the end position of PDSCH corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T1, it is determined that the timeline requirement is met, and then URLLC HARQ-ACK and URLLC SR perform multiplexing transmission.

Example 5:

assuming that there is time-domain overlap between PUCCH resources carrying URLLC HARQ-ACK and PUCCH resources carrying eMBB SR, as shown in fig. 6, eMBB SR information with lower priority is directly discarded, and only HARQ-ACK information with higher priority is transmitted.

Example 6:

assuming that there is overlap in time domain among PUCCH resources carrying URLLC HARQ-ACK, PUCCH resources carrying URLLC SR, and PUCCH resources carrying eMBB CSI, as shown in fig. 7, eMBB CSI information with lower priority is directly discarded, and only URLLC HARQ-ACK and URLLC SR information with higher priority is transmitted. Further, since the PUCCH resource of URLLC HARQ-ACK and the PUCCH resource of URLLC SR are overlapped, the UE needs to determine whether the two overlapped channels meet the timeline requirement, and since the PUCCH resource carrying URLLC HARQ-ACK is ahead of the PUCCH resource carrying SR, and the interval between the end position of DCI corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T2, and the interval between the end position of PDSCH corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T1, it is determined that the timeline requirement is met, and then URLLC HARQ-ACK and URLLC SR perform multiplexing transmission.

Example 7:

supposing that there is time domain overlap between a PUCCH carrying URLLC HARQ-ACK, a PUCCH carrying URLLC SR and a PUCCH resource carrying eMBB CSI, and since there is overlap between the PUCCH resource carrying URLLC HARQ-ACK and the PUCCH resource carrying URLLC SR, the UE first needs to process the two overlapping channels of the same service type, specifically, the UE determines whether the two overlapping channels meet the timeline requirement, and since the PUCCH resource carrying URLLC HARQ-ACK leads the PUCCH resource carrying SR, and the interval between the end position of DCI corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T2, and the interval between the end position of PDSCH corresponding to URLLC HARQ-ACK and the PUCCH start position of URLLC HARQ-ACK is greater than T1, it is determined that the timeline requirement is met, the URLLC HARQ-ACK and URLLC are multiplexed.

Assuming that the multiplexing resources of URLLC HARQ-ACK and URLLC SR are newly selected PUCCH resources, case one: as shown in fig. 8, the newly selected PUCCH resource and the PUCCH resource of the eMBB CSI do not overlap in the time domain, and then the UE transmits the eMBB CSI and the multiplexed URLLC HARQ-ACK and URLLC SR on two non-overlapping resources, respectively; case two: as shown in fig. 9, the resource of URLLC HARQ-ACK multiplexed by URLLC SR is transmitted, and since PUCCH resource of URLLC HARQ-ACK and PUCCH resource of eMBB CSI are overlapped in time domain, the processing is further performed according to the overlapping scheme of different traffic types, for example, eMBB CSI is directly discarded, and URLLC HARQ-ACK and URLLC SR are multiplexed and transmitted only on PUCCH resource of URLLC HARQ-ACK.
