Background

In 5G, the method is divided into 3 large application scenes according to service requirements: eMBB, mMTC, uRLLC. The IIoT stand considers that under the sub-issue of priority in the user, the scene of introducing various conflicts is supported. R16 supports a scenario of multiple resource collisions, for which the UE MAC may group one MAC PDU per grant, but only one MAC PDU is sent, another MAC PDU cannot be transmitted due to the resource collision. According to the prior art, the UE does not have special provisions on how MAC PDUs that cannot be transmitted due to resource collision are handled, nor is the network aware that this problem exists. This will cause the MAC PDU of this group to be flushed (corresponding HARQ process is transmitted according to the new transmission), causing unnecessary data loss, the URLLC QoS cannot be guaranteed, and even serious errors in industrial operation. How to make the network aware of this problem, and solve this problem, is not determined by the existing standards.

For a more complete understanding of the nature and the technical content of the embodiments of the present invention, reference should be made to the following detailed description of embodiments of the invention, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the invention.

The embodiment of the invention provides an information processing method, which is applied to UE (user equipment), and as shown in FIG. 2, comprises the following steps:

step 21: and sending information to the network equipment, wherein the information is at least used for assisting the network equipment to determine that the first MAC PDU which is not successfully sent exists at the terminal equipment side.

The unsuccessfully transmitted first MAC PDU may be at least one of the following: the method comprises the steps of transmitting failed MAC PDUs, untransmitted MAC PDUs, conflicting MAC PDUs, MAC PDUs corresponding to resource conflicts, MAC PDUs with low priority, pre-scheduled/scheduled MAC PDUs, and grouping the MAC PDUs which are not transmitted on an air interface.

In this embodiment, the network device may be a base station, and the UE may be a mobile terminal. The following description is made with respect to the scheme provided in this embodiment, using various scenarios:

scene one,

The second MAC PDU sent to the network equipment carries first indication information, and the first indication information is used for informing the network equipment that the first MAC PDU which is not successfully sent exists at the terminal equipment side.

MAC PDUs that cannot be transmitted due to resource overlap are likely to be flushed directly, causing unnecessary data loss problems. This would bring about a further disadvantage if the traffic of URLLC were contained therein: the loss of URLLC data causes that the URLLC QoS cannot be guaranteed, even in case of major errors in industrial operation. Therefore, how to let the network know this problem and to perform retransmission scheduling needs to be considered and solved. The scheme provided in the scene is that the first indication information is carried in the second MAC PDU and is used for informing the network that the MAC PDU which is overlapped/drope exists or that the MAC PDU which is packed but can not be transmitted exists.

The first indication information is carried in a second MAC PDU, which may be at least one of the following: the method comprises the steps of preferentially transmitting MAC PDUs, high-priority MAC PDUs, MAC PDUs corresponding to preferentially transmitted resources, MAC PDUs corresponding to later-arriving resources, post-processing MAC PDUs, post-packet MAC PDUs, MAC PDUs corresponding to later-processing resources and specific MAC PDUs.

The later-arriving resource may be the last-arriving resource in the plurality of overlapping resources.

In the MAC PDU corresponding to the specific resource, the specific resource may be at least one of the following: a specific identified resource, a specific priority resource (grant), a specific type of resource grant; the specific type may be CG type (type) x, dynamic resource (dynamic grant). It should also be noted that the specific priority may be a priority higher than the threshold, or may be a priority within a preset priority range, or may be a specified priority, for example, may be specified for the terminal device on the network side, or may, of course, be defined in advance by the terminal device itself, or may be in another setting manner, which is not exhaustive here.

At least one of the specific MAC PDU, the specific priority MAC PDU, the specific identification MAC PDU, the MAC PDU indicated by the network equipment, the MAC PDU containing the specific priority logic channel and/or the MAC CE, the MAC PDU containing the specific identification logic channel and/or the MAC CE.

Wherein the first indication information may be a first MAC CE.

And carrying the first indication information in the second MAC PDU when the first condition is met.

Wherein the first condition is at least one of:

there are overlapping resources; that is, the first indication information may be carried as long as it is determined that there is currently an overlapping resource;

the first MAC PDU has been packetized; the first indication information can be determined to be carried only if one MAC PDU is packed, or the condition that the overlapping resources exist is combined;

there is a first MAC PDU that is not transmitted due to the existence of overlapping resources; that is, the first indication information is carried because there is an overlapping resource and the first MAC PDU therein is not successfully transmitted or not transmitted because the resource is overlapped;

the first MAC PDU has been packetized and either failed to transmit or not transmitted; whether a second MAC PDU or more exists or not at present, the first indication information can be carried as long as one MAC PDU is packed and is not successfully transmitted;

the first MAC PDU and the second MAC PDU are different in HARQ process; namely, when the HARQ processes of the two MAC PDUs are different, one MAC PDU is considered to be possibly unsuccessfully transmitted and carries first indication information;

the first MAC PDU and the second MAC PDU have the same HARQ process; namely, when the HARQ processes of the two MAC PDUs are the same, one MAC PDU is considered to be possibly unsuccessfully transmitted and carries first indication information;

There is a first MAC PDU that is either not transmitted or that is overlapped or discarded (overlapped);

there are certain types of MAC PDUs; for example, there are drop MAC PDUs;

the second MAC PDU grouping time is later than the minimum priority processing time; that is, as long as there is one MAC PDU grouping time later, it can be considered that there is one MAC PDU that may be covered, and the first indication information can be carried for a long time.

It should also be understood that the above conditions may be used alone or in combination of two or more thereof; for example, if there are overlapping resources and the first MAC PDU is already packetized and transmission fails or is not transmitted, it may be determined that the first MAC PDU cannot be correctly transmitted due to the overlapping resources, and at this time, the first indication information may be transmitted. Of course, other conditions may be used in combination, or all conditions may be used in combination, and this embodiment is not intended to be exhaustive.

It should be noted that, in the case where the HARQ processes of the first MAC PDU and the second MAC PDU are different, at least one of the following processes may be performed:

at least part of the first MAC PDU is contained in the second MAC PDU; at least a portion of the first MAC PDUs that are not included in the second MAC PDUs by the flush; consider that one of the MAC PDUs may not be successfully transmitted; carrying first indication information; flush or discard the first MAC PDU; the HARQ buffer of the first MAC PDU is cleared; discarding the first MAC PDU when the corresponding resource sizes or attribute parts of the two MAC PDUs are different or completely different; when the corresponding resource sizes or attributes of the two MAC PDUs are partially the same or partially the same, at least part of the first MAC PDU is contained in the second MAC PDU; rollback at least part of the data not contained in the second MAC PDU to the RLC layer; modifying RLC corresponding parameters and timers

Alternatively, for the case where the HARQ processes of the first MAC PDU and the second MAC PDU are the same, at least one of the following processes may be performed:

flush or discard the first MAC PDU; consider that one of the MAC PDUs was not successfully transmitted; the carrying indication information indicates the loss of a base station data packet or the collision of HARQ processes; carrying first indication information; at least part of the first MAC PDU is contained in the second MAC PDU; at least a portion of the first MAC PDUs that are not included in the second MAC PDUs by the flush; discarding the first MAC PDU when the corresponding resource sizes or attribute parts of the two MAC PDUs are different or completely different; when the HARQ processes of the two MAC PDUs are the same and the corresponding resource sizes or attributes are partially the same or partially the same, at least part of the first MAC PDU is contained in the second MAC PDU; rollback at least part of the data not contained in the second MAC PDU to the RLC layer; modifying RLC corresponding parameters and timers

It should be noted that, for at least one of the above two schemes, that is, the scheme of the case where the first MAC PDU and the second MAC PDU HARQ process are different, and/or the scheme of the case where the first MAC PDU and the second MAC PDU HARQ process are the same, it is applicable to any one of the scenarios in the present invention, or a combined scenario of any of the scenarios.

It should be noted that, in the case of collision, the MAC may generate at least one MAC PDU. For example, in case of two resource collisions, the MAC may generate one or two MAC PDUs.

Optionally, the MAC generates a MAC PDU when at least one of the following scenarios:

the arrival time of the second resource is no later than the MAC PDU grouping, and the second resource is a conflicted resource;

the time of receiving the second resource is no later than the time of receiving the MAC PDU grouping packet, and the resource is a conflicted resource;

processing the second resource, which is a conflicted resource, at a time not later than the MAC PDU grouping;

the second resource is received or acquired before the MAC PDU is packed;

the conflicted resources are received or acquired before the MAC PDU is packed;

all conflicted resources are received or obtained before the MAC PDU is packed;

the second resource arrives later than the MAC PDU group packet, and the second resource pre-scheduled or not transmitted preferentially, the resource is the conflicted resource; the MAC PDU may be a MAC PDU corresponding to any one of the conflicted resources, or any one of conflicted MAC PDUs, or may be understood as a first MAC PDU;

the time of receiving the second resource is later than the time of the MAC PDU packet, and the second resource is pre-scheduled or is not transmitted preferentially, and the resource is a conflicted resource; the second resource may be understood as a resource corresponding to the second MAC PDU, or may be a second PUSCH;

Processing the second resource later than the MAC PDU grouping packet, wherein the second resource pre-transmitted or not transmitted preferentially, and the resource is a conflicted resource;

the second resource is received or acquired after the MAC PDU is packed, and the second resource is pre-scheduled or is not transmitted preferentially;

the second resource arrives later than the MAC PDU grouping packet, and the first resource is transmitted preferentially, and the resource is a conflicted resource; the MAC PDU may be a MAC PDU corresponding to any one of the conflicted resources, or any one of conflicted MAC PDUs, or may be understood as a first MAC PDU;

the time of receiving the second resource is later than the time of the MAC PDU grouping packet, and the first resource is transmitted preferentially, wherein the resource is a conflicted resource;

processing the second resource later than the MAC PDU grouping package, and transmitting the first resource preferentially, wherein the resource is a conflicted resource;

the second resource is received or acquired after the MAC PDU is packed, and the first resource is transmitted preferentially; wherein the first resource may correspond to one of: the first MAC PDU, the high-priority resource, carry the resource of the specific logical channel, meet the resources of the specific logical channel LCP that dispose, the resources of the specific attribute (PUSCH, MCS);

first resource priority transmission;

the conflicted resources are not received or known before the MAC PDU is packed;

All conflicted resources are not received or known before the MAC PDU is packed;

the first and second MAC PDU HARQ process numbers or processes are the same (at this time, e.g., only the first MAC PDU or the second MAC PDU is generated)

The first MAC PDU has been packetized or transmitted;

specifically, the first resource may correspond to one of the following: the first MAC PDU, the high-priority resource, carry the resource of the specific logical channel, meet the resources of the specific logical channel LCP that dispose, the resources of the specific attribute (PUSCH, MCS); the MAC PDU may be a MAC PDU corresponding to any one of the conflicted resources, or any one of the conflicted MAC PDUs, or may be understood as the first MAC PDU; the second resource may be understood as a resource corresponding to the second MAC PDU, or may be a second PUSCH.

In addition, the MAC generates more than one MAC PDU when at least one of the following scenarios:

for example, the MAC generates two MAC PDUs when at least one of the following scenarios:

the arrival time of the second resource is later than the MAC PDU grouping packet, and the second resource is transmitted preferentially, and the resource is a conflicted resource;

the time of receiving the second resource is later than the time of the MAC PDU grouping packet, and the second resource is transmitted preferentially, and the resource is a conflicted resource;

processing the second resource later than the MAC PDU grouping packet, and transmitting the second resource preferentially, wherein the second resource is a conflicted resource;

The second resource is received or acquired after the MAC PDU is packed, and the second resource is transmitted preferentially;

data available of a logic channel with higher priority after the MAC PDU is packed;

data arrival or burst of the priority logical channel;

the first MAC PDU has been packetized or transmitted.

It should be understood that, the description of the MAC PDU and the second resource is the same as that described above, and will not be repeated.

Optionally, if the MAC receives the second resource after grouping the first MAC PDU, if the data available of the logical channel with higher priority, or the second resource priority is higher, or the MAC PDU corresponding to the second resource may carry the logical channel with higher priority or its data than the logical channel corresponding to the first MAC PDU (i.e. the original MAC PDU), the MAC generates another MAC PDU, and transmits the other MAC PDU to the physical layer; otherwise, the MAC layer discards the resource and does not generate another MAC PDU (i.e., the second MAC PDU).

It should be noted that, for at least one of the above two schemes, i.e., a scheme for generating one MAC PDU and/or a scheme for generating more than one MAC PDU, it is applicable to any one of the scenarios or a combination scenario of any of the scenarios in the present invention.

The following is exemplified by CG and dynamic resource (dynamic grant) conflict:

the network instructs uplink data transmission by dynamic scheduling, and instructs grant information to be used in the PDCCH.

The UE receives the grant indicated in the first step. The UE packetizes this grant to generate a first MAC PDU.

The UE finds out the grant resource conflict (such as time domain conflict, frequency domain conflict, or time-frequency domain conflict) between the grant indicated in the first step and the pre-configured CG, and determines that the CG grant has a high priority and needs to be transmitted preferentially. As shown in fig. 3, the UE packs another MAC PDU, such as a second MAC PDU, for the CG grant, and carries a first MAC CE in the second MAC PDU, where the first MAC CE is used to notify the peer entity that there is overlapped MAC PDU, or there is an unsent MAC PDU due to resource overlapping, or the MAC PDU of the pack corresponds to the uplink resource of the drop.

The UE sends a second MAC PDU to the correspondent entity, such as a base station.

Accordingly, the base station determines that there is such a situation, such as a MAC PDU that has been overlapped and not transmitted, according to the first MAC CE in the second MAC PDU. At this time, the base station may perform retransmission scheduling on the HARQ process corresponding to the first MAC PDU.

Scene two,

And carrying second information in a second MAC PDU sent to the network equipment, wherein the second information carries at least part of contents in the first MAC PDU which is not successfully sent by the terminal equipment side.

The difference from the first scenario is that the present scenario does not need to notify the network of the problem, and directly carries the MAC CE and/or data in the overlapped MAC PDU in the MAC PDU of the priority transmission, so as to avoid discarding the data with high QoS requirement or discarding the important MAC CE.

The second information is carried in the second MAC PDU, where the second information is a MAC CE and/or a MAC SDU in the first MAC PDU, and an explanation of the second MAC PDU is the same as that of the first MAC PDU, which is not described herein.

The second information is part of or all of the MAC CEs and/or MAC SDUs in the first MAC PDU.

Alternatively, the MAC may perform at least one of:

at least part of the first MAC PDU is contained in the second MAC PDU; at least a portion of the first MAC PDUs that are not included in the second MAC PDUs by the flush; if the HARQ processes corresponding to the first MAC PDU and the second MAC PDU are different, flushing the HARQ buffer of the first MAC PDU; consider that one of the MAC PDUs may not be successfully transmitted; if the HARQ processes corresponding to the first MAC PDU and the second MAC PDU are the same, retransmitting the first MAC PDU; when the HARQ processes of the two MAC PDUs are identical and the corresponding resource sizes or attributes are partially identical or partially identical, at least part of the first MAC PDU is included in the second MAC PDU.

Further, the second information in the second information includes:

the indicated logical channel identification corresponds to the data and/or MAC CE of the logical channel;

and/or information in the first MAC PDU that can be placed in the second MAC PDU, determined according to predefined rules.

Specifically, the indicated logical channel identifier may be at least one of the following MAC CEs: BSR MAC CE, PHR MAC CE or acknowledgement (Confirmation) MAC CE.

The predefined rule includes at least one of:

data of a specific identified logical channel; the specific identified logical channel may be configured for the UE by the network device, or may be predefined by the terminal device itself, or may be preconfigured to the terminal device, as specified by the protocol;

data of a logical channel of a specified priority; wherein, the designated priority can be configured or predefined for the network device;

data of a logic channel with a priority higher than a preset threshold value; for example, if there are currently 5 priorities, then the preset threshold value may be priority 2, and then the data of the logical channel higher than priority 2 may be contained in the second MAC PDU;

data of logical channels having priorities within a specific priority range or threshold value; the network device can be configured for the network device, or the terminal device can be predefined by itself, or the network device can be preconfigured for the terminal device, such as the protocol is well defined;

The identification information of the logical channel is data of the logical channel in a preset identification range; for example, one identifier may be designated, or a plurality of identifiers may be designated, so long as data of a logical channel within the designated one or more identifiers may be contained in the second MAC PDU; alternatively, data of one logical channel may be randomly selected from a plurality of logical channels or selected (e.g., prioritized) according to a certain rule to be included in the second MAC PDU;

a preset type of MAC CE and/or a preset type of MAC SDU; the preset type may be configured for the network device, predefined for the UE or predefined/selected by the UE itself; for example, the buffer status may be BSR MAC CE, but may be other types of MAC CE, and is not exhaustive.

It should also be noted that the predefined rules described above may be used alone or in combination; for example, the method includes that a logic channel with a priority within a specific range is included, then a preset type of MAC CE is selected and added into a second MAC PDU; alternatively, other combinations are possible and are not exhaustive.

The following are exemplified by CG and dynamic grant conflict, see fig. 4:

and in the overlapped MAC PDU of the network configuration, the identifier of the logical channel corresponding to the corresponding data in the overlapped MAC PDU can be carried, and/or the type of the MAC CE (such as BSR MAC CE) can be carried.

For example, the network indicates a specific logical channel identification, and data of the logical channel corresponding to the identification may be placed in the second MAC PDU;

for example, the network indicates a particular logical channel priority, and data of a logical channel corresponding to the priority may be placed in the second MAC PDU;

for example, the network indicates a particular logical channel priority or identifies a threshold above which data for logical channels may be placed in the second MAC PDU, or data identifying logical channels within this threshold may be placed in the second MAC PDU;

for example, a type of MAC CE (e.g., BSR MAC CE) that may be carried, the BSR MAC CE may be placed in the second MAC PDU.

Or, according to information indicated by DCI or information of grant, determining information in the first MAC PDU which can be placed in the second MAC PDU.

The UE receives a grant indicated by the network device. The UE packetizes this grant to generate a first MAC PDU.

The UE discovers the grant indicated by the network device and the grant resource conflict (such as time domain conflict, frequency domain conflict, or time-frequency domain conflict) of the preconfigured CG, and determines that the CG grant has high priority and needs to be transmitted preferentially. The UE packs the CG grant group with another MAC PDU, such as a second MAC PDU, and carries second information in the second MAC PDU, and according to network configuration, the second MAC PDU carries data corresponding to a logical channel corresponding to the indicated logical channel identifier and/or BSR MAC CE

Alternatively, the UE may determine which information in the first MAC PDU may be placed in the second MAC PDU according to predefined rules.

Optionally, after the second MAC PDU packet is completed according to the existing LCP, if there are remaining resources, the second information is considered to be carried. Or after the information in the first MAC PDU is taken out, reselecting and putting the information into a resource pool, and then carrying out the existing LCP for packaging.

Optionally, after at least part of the first MAC PDU is included in the second MAC PDU; at least a portion of the first MAC PDUs that are not included in the second MAC PDUs by the flush; and if the HARQ processes corresponding to the first MAC PDU and the second MAC PDU are different, flushing the HARQ buffer of the first MAC PDU.

Transmitting a second MAC PDU to a correspondent entity (e.g., a base station);

accordingly, the base station acquires part or all of the information in the first MAC PDU which is not transmitted due to overlapping according to the second information in the second MAC PDU.

Scene three,

When the physical layer transmits a second PUSCH or a second reference signal, carrying third indication information, wherein the third indication information is used for informing network equipment that a first MAC PDU which is not successfully transmitted exists at the terminal equipment side;

or when the physical layer sends the second PUCCH or the second SR, carrying third indication information, wherein the third indication information is used for informing the network equipment that the first MAC PDU which is not successfully sent exists at the terminal equipment side.

When the physical layer sends a second PUSCH or a second reference signal or a second PUCCH or a second SR, carrying third indication information, for informing the network that there is a MAC PDU due to overlap or that there is a MAC PDU that is packetized but cannot be transmitted):

the first difference from the scene is that: the present scenario adopts a physical layer notification manner, and the first scenario is a MAC layer notification manner.

The second PUSCH may be at least one of: the PUSCH of the priority transmission, the PUSCH of the post arrival, the PUSCH of the post processing, the PUSCH of the post group package, and the specific PUSCH.

Wherein, the specific PUSCH may be one of the following: grant of specific priority, grant of specific type, grant of specific MAC PDU, grant of high priority LCH and/or MAC CE, grant of specific identification LCH and/or MAC CE, grant of specific LCH and/or MAC CE, network device indication.

The following is a description of CG and dynamic grant conflict examples, with reference to fig. 5-1 and 5-2:

The UE receives the grant indicated in the first step. The UE MAC packetizes this grant, generating a first MAC PDU.

The UE MAC finds out the grant resource collision (e.g., time domain collision, frequency domain collision, or time-frequency domain collision) between the grant indicated in the first step and the pre-configured CG, and the UE MAC determines that the CG grant has a high priority and needs to be transmitted preferentially. The UE packs another MAC PDU, such as a second MAC PDU, for the CG grant.

The UE physical layer indicates third indication information to the network when transmitting PUSCH of the second MAC PDU (second MAC PDU). The UE physical layer may receive only one MAC PDU or two MAC PDUs.

Alternatively, the third indication information may be at least one of the following (the information may be a network configuration, an indication, or predefined):

second scrambling code (e.g., PUSCH carrying the information employs the second scrambling code, and PUSCH not carrying the information employs the first scrambling code)

Second port (e.g., PUSCH with this information employs second port, and first port is employed without carrying)

Second sequence (e.g., PUSCH carrying the information employs the second sequence, and first sequence is not carried)

Optionally, if the UE physical layer receives two MAC PDUs, the UE physical layer determines, according to the UE MAC indication, or the grant information, or the network indication, that grant is the second PUSCH.

The UE physical layer transmits the second PUSCH using the second scrambling code and/or the second port and/or the second sequence, which represents that there is such a problem (there is MAC PDU due to overlap or there is a MAC PDU that is packetized but cannot be transmitted). Otherwise, the UE physical layer adopts the first scrambling code and/or the first port and/or the first sequence to send the second PUSCH.

The base station determines whether the situation exists according to the scrambling code and/or the port adopted by the second PUSCH transmission, such as the MAC PDU which is not transmitted and has the resource overlapped. At this time, the base station may perform retransmission scheduling on the HARQ process corresponding to the first MAC PDU.

It should be noted that this method is also used in the scenarios of PUCCH/SR and PUSCH collisions. For example, if the first MAC PDU corresponds to the conflicted PUSCH and the first MAC PDU is pre-scheduled, the physical layer informs the network that there is a drop MAC PDU using the third indication information.

Further, for any of the above scenarios, at least one of the following operations may be included: the first MAC PDU and/or the HARQ buffer corresponding to the first MAC PDU are/is emptied;

when the second MAC PDU is sent, the first MAC PDU and/or the HARQ buffer corresponding to the first MAC PDU are emptied;

when the first MAC PDU is a drop MAC PDU, the first MAC PDU and/or an HARQ buffer corresponding to the first MAC PDU are emptied;

when a second PUSCH and/or a second reference signal is sent, the first MAC PDU and/or an HARQ buffer corresponding to the first MAC PDU are emptied;

when a second PUCCH and/or a second SR signal is sent, the first MAC PDU and/or an HARQ buffer corresponding to the first MAC PDU are emptied;

When the first indication information is sent, the first MAC PDU and/or the HARQ buffer corresponding to the first MAC PDU are emptied;

when the second information is sent, the first MAC PDU and/or the HARQ buffer corresponding to the first MAC PDU are emptied;

when the third indication information is sent, the first MAC PDU and/or the HARQ buffer corresponding to the first MAC PDU are emptied;

The first MAC PDU constitutes an untransmitted; with the further constraint added, the first MAC PDU grouping, but not transmitted, is transmitted;

the resource corresponding to the second MAC PDU is transmitted; that is, if the first MAC PDU overlaps with the resource of the second MAC PDU, and at this time, the resource corresponding to the second MAC PDU is already transmitted, then the first MAC PDU may be transmitted, and it is understood that the first MAC PDU may be transmitted when not transmitted, or retransmitted when not transmitted successfully;

the resources corresponding to the first MAC PDU are overlapping resources; that is, as long as the first MAC PDU is an overlapping resource, it can be considered as an object that needs to be retransmitted or transmitted;

The resource priority corresponding to the first MAC PDU is low; at this time, it can be considered that it is covered by other resources because of the lower priority of the resources, and then it is determined to transmit or retransmit it;

the resource corresponding to the second MAC PDU is transmitted preferentially; that is, when there are overlapping resources, one of the resources has a higher priority, and can transmit its corresponding second MAC PDU preferentially, then the first MAC PDU of the remaining overlapped or covered resources needs to be transmitted or retransmitted;

the first MAC PDU has a low priority;

the second MAC PDU has a high priority; corresponding to the previous one, the MAC PDU with higher priority is transmitted before, and then one MAC PDU with lower priority can be transmitted or retransmitted after a period of time;

Wherein the first HARQ process is the nearest HARQ process and is different from or the same as the original HARQ process transmitting the first MAC PDU. Wherein the nearest one HARQ may be any HARQ process after the point in time of the first MAC PDU process, or a specific one HARQ process, or one HARQ process of a class.

Regarding the manner of retransmitting or transmitting the first MAC PDU, it may be: and packaging at least part of data groups in the first MAC PDU into a third MAC PDU. Wherein the partial data may be at least one of: subPDU, or SDU and/or MAC CE.

And the resources corresponding to the third MAC PDU are new transmission resources, or resources with NDI turned over, or resources with the same HARQ process number as the resources corresponding to the first MAC PDU or new transmission resources. The HARQ process with the same resource or new transmission resource as the HARQ process number corresponding to the first MAC PDU may be an HARQ process corresponding to the first MAC PDU or an HARQ process corresponding to the grant for transmitting the first MAC PDU.

Or, the resource corresponding to the third MAC PDU is the nearest resource.

Or, the resource corresponding to the third MAC PDU is a latest new transmission resource. For both, the most recent one may be any one of the resources after the point in time of the first MAC PDU process, or a particular one of the resources, or one of the resources of the class.

The transmitting the data in the first MAC PDU includes:

transmitting data in the first MAC PDU by using a third resource; for example, a portion of the data in the first MAC pdu, such as a subPDU, or an SDU and/or MAC CE may be transmitted;

when the second information is included in the second MAC PDU, at least part of the first MAC PDU not included in the second MAC PDU is cleared.

It may be appreciated that when the third MAC PDU or the second MAC PDU includes the second information, whether to empty the corresponding HARQ buffer and/or data of the first MAC PDU may be determined according to whether the first MAC PDU is partially included in the second or third MAC PDU; or may determine whether to empty the corresponding HARQ buffer and/or data of the first MAC PDU based on whether the process number is the same as the first MAC PDU.

The embodiment also provides an information processing method, which is applied to a network device, as shown in fig. 6, and includes:

step 31: carrying out retransmission scheduling;

wherein the retransmission-scheduled object comprises one of:

specific resources, resources with overlap, specific HARQ, unreceived PUSCH, first MAC PDU with overlap of resources, first MAC PDU with drop MAC PDU.

Specifically, the scheme at the network device side provided in this embodiment may perform retransmission scheduling when at least one of the first indication information, the second information, and the third indication information is received;

The first indication information is used for informing the network equipment that a first MAC PDU which is not successfully transmitted exists at the terminal equipment side; the second information carries at least part of content in the first MAC PDU which is not successfully transmitted by the terminal equipment side; the third indication information is used for notifying the network equipment that the first MAC PDU which is not successfully transmitted exists at the terminal equipment side based on at least one of the second scrambling code, the second port and the second sequence.

The network device may be configured to perform retransmission scheduling all the time, or may perform retransmission scheduling when any one of the information is received; alternatively, the retransmission scheduling may be performed when a certain condition is satisfied.

The description can be made in various scenarios:

scene 1,

The scene receives first indication information carried in a second MAC PDU sent by terminal equipment; and determining that the terminal equipment has the unsuccessfully transmitted first MAC PDU based on the first indication information.

MAC PDUs that cannot be transmitted due to resource overlap are likely to be flushed directly, causing unnecessary data loss problems. This would bring about a further disadvantage if the traffic of URLLC were contained therein: the loss of URLLC data causes that the URLLC QoS cannot be guaranteed, even in case of major errors in industrial operation. Therefore, how to let the network know this problem and to perform retransmission scheduling needs to be considered and solved. The scheme provided in the scene is that the first indication information is carried in the second MAC PDU and is used for informing the network that the MAC PDU which is due to overlap exists or the MAC PDU which is packed but can not be transmitted exists.

Wherein the first indication information may be a first MAC CE.

Scene 2,

Indicating the identity of the indicated logical channel and/or the type of the MAC CE which the terminal equipment can carry in the second information;

correspondingly, the second information can be carried in a second MAC PDU sent by the terminal equipment, and the second information carries at least part of the content in the first MAC PDU which is not successfully sent by the terminal equipment side.

Scene 3,

Receiving a second PUSCH and/or a second reference signal sent by the terminal equipment at a physical layer;

and determining whether a third indication information is carried in the second PUSCH or the second reference signal or not based on a scrambling code and/or a port and/or a sequence adopted by the second PUSCH and/or the second reference signal, wherein the third indication information is used for informing the network equipment that the first MAC PDU which is not successfully transmitted exists at the terminal equipment side.

And/or the number of the groups of groups,

the network equipment receives a second PUCCH and/or SR sent by the terminal equipment at a physical layer;

And determining whether third indication information is carried or not based on scrambling codes and/or ports and/or sequences adopted by the second PUCCH and/or the SR, wherein the third indication information is used for informing the network equipment that the first MAC PDU which is not successfully transmitted exists at the terminal equipment side.

Specifically, when at least one of the second scrambling code, the second port and the second sequence adopted by the second PUSCH, it is determined that the third indication information is received.

The difference from scenario 1 is that: the present scenario adopts a physical layer notification manner, and the first scenario is a MAC layer notification manner.

Wherein, the specific PUSCH may be one of the following: grant of a specific priority, grant of a specific type, inclusion of a specific MAC PDU, network device indication.

The specific type may be CG type x or dynamic grant.

Optionally, the third indication information is at least one of the following: a second scrambling code, a second port, a second sequence.

The second scrambling code may be a sequence of a second reference signal, such as a DMRS sequence, a second PUSCH scrambling code, and a second RNTI;

the second port may be a port of the second reference information, such as a second DMRS port.

The second sequence, such as a PUCCH sequence, the different PUCCH resources correspond to different spreading sequences and/or different SR sequences.

The second scrambling code, the second port, the second sequence may all be indicated by the network device for the terminal device or may be predefined for the UE itself.

Scene 4,

And when the third condition is met, determining that the HARQ process corresponding to the first MAC PDU with the overlapped resources is subjected to retransmission scheduling.

Or, the base station always performs retransmission scheduling on the overlapped or pre-scheduled resources.

MAC PDUs that cannot be transmitted due to resource overlapping are likely to be flushed directly, causing unnecessary data loss problems. This would bring about a further disadvantage if the traffic of URLLC were contained therein: the loss of URLLC data causes that the URLLC QoS cannot be guaranteed, even in case of major errors in industrial operation. Therefore, how to let the network know this problem and to perform retransmission scheduling needs to be considered and solved.

The present scenario is purely network-side behavior, other embodiments are UE-side behavior.

The third condition includes at least one of:

there is a resource overlap;

at the time of resource conflict, receiving a PUSCH corresponding to the second MAC PDU;

at the time of resource collision, only the PUSCH corresponding to one MAC PDU is received.

The following are exemplified by CG and dynamic grant conflicts, see fig. 7:

the network instructs uplink data transmission by dynamic scheduling, and instructs grant information and HARQ process 1 to be used in the PDCCH.

The UE receives the grant indicated in the first step. The UE packetizes this grant, generating a first MAC PDU corresponding to HARQ process 1.

The UE finds out the grant resource conflict (such as time domain conflict, frequency domain conflict, or time-frequency domain conflict) between the grant indicated in the first step and the pre-configured CG, and determines that the CG grant has a high priority and needs to be transmitted preferentially. The UE packets another MAC PDU, e.g., a second MAC PDU, for the CG grant corresponding to HARQ process 2. The UE sends the PUSCH corresponding to the second MAC PDU to the network

The base station determines that the grant in the first step is overlapped based on the received PUSCH. The network determines that the HARQ process corresponding to the grant given in the first step is required to be retransmitted corresponding to the HARQ process 1 process. At this time, the base station performs retransmission scheduling on the HARQ process corresponding to the first MAC PDU.

An embodiment of the present invention provides a UE, as shown in fig. 8, including:

And the resources corresponding to the third MAC PDU are new transmission resources, or resources with NDI turned over, or resources with the same HARQ process number as the resources corresponding to the first MAC PDU or new transmission resources.
