Background
When the data of the industrial internet is non-periodic and occurs occasionally, the base station cannot sense the arrival of the data in advance, and the data is authorized to be carried by using uplink configuration due to the ultra-low time delay requirement of the industrial internet of things. Therefore, the base station dynamically schedules (e.g., a Physical Uplink Shared Channel (PUSCH) scheduled by Downlink Control Information (DCI)) the data carried by the Physical Uplink Shared Channel and the data authorized by the Uplink configuration may collide with each other. Or, due to the consideration of saving resources or matching any period of the service, the physical resources of multiple configuration grants may partially overlap, and thus, a conflict may occur between data of multiple configuration grants.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Additionally, the terms "system" and "network" are often used interchangeably herein.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
As shown in fig. 1, a processing method for data transmission according to an embodiment of the present invention is executed by a user equipment, and includes:
step 101, when the physical layer of the ue receives a second MAC PDU after receiving a first MAC PDU, and the priority of the logical channel corresponding to the first MAC PDU is lower than the priority of the logical channel corresponding to the second MAC PDU,
if the first MAC PDU is transmitted, sending first information to an MAC layer of the user equipment, wherein the first information is used for indicating retransmission or new transmission of the second MAC PDU;
and if the first MAC PDU is not transmitted, transmitting the first MAC PDU or the second MAC PDU according to a target priority, wherein the value of the target priority is a common priority value between a physical layer and an MAC layer.
Thus, under the condition that the physical layer of the user equipment receives a first MAC PDU which is sent by the MAC layer and has lower logical channel priority and then receives a second MAC PDU which is sent by the MAC layer and has higher logical channel priority, if the physical layer transmits the first MAC PDU, first information which indicates the retransmission or new transmission of the second MAC PDU is sent to the MAC layer; if the physical layer has not transmitted the first MAC PDU, the first MAC PDU or the second MAC PDU is transmitted according to a target priority, wherein the value of the target priority is a common priority value between the physical layer and the MAC layer. Therefore, the priority conflict between the physical layer and the MAC layer during data transmission can be solved, the overlong transmission delay is avoided, and the transmission efficiency is improved.
It should be appreciated that the retransmission or retransmission in this embodiment may be an automatic retransmission or retransmission of the MAC PDU, or a scheduled retransmission or retransmission of the MAC PDU.
Of course, the physical layer of the ue will retransmit or newly transmit the second MAC PDU after receiving the first information. Therefore, the first MAC PDU and the second MAC PDU can be transmitted in a physical layer, and the transmission requirement is met.
And the target priority is not a logical channel priority, the value of the target priority is used as a value of a common priority between the physical layer and the MAC layer, and when the physical layer receives the first MAC PDU and then receives the second MAC PDU, the physical layer determines to transmit the first MAC PDU or the second MAC PDU by comparing the value of the target priority of the first MAC PDU with the value of the target priority of the second MAC PDU.
And the physical layer performs priority transmission on the MAC PDU with higher target priority in the first MAC PDU and the second MAC PDU based on the target priority.
In addition, for a MAC PDU with a lower target priority and not transmitted by the physical layer, optionally, the method in this embodiment further includes:
and after the first MAC PDU or the second MAC PDU is transmitted according to the target priority, second information is sent to the MAC layer of the user equipment, and the second information is used for indicating retransmission or new transmission of the MAC PDU which is not transmitted.
Thus, after receiving the second information, the physical layer of the ue can retransmit or newly transmit the MAC PDU that is not transmitted due to the lower target priority in the first MAC PDU and the second MAC PDU. And the transmission of the first MAC PDU and the second MAC PDU in a physical layer is also realized, and the transmission requirement is met.
Optionally, in this embodiment, the target priority is the maximum priority of the logical channel priority and the physical channel priority, or the sum of the logical channel priority and the physical channel priority.
That is, in the face of a conflict of inter-layer priorities, the target priority on which the physical layer transmission is based is the maximum priority among the logical channel priority and the physical channel priority, or the sum of the logical channel priority and the physical channel priority. Of course, the specific value of the target priority is pre-configured, such as inter-layer negotiation.
Supposing that the logical channel priority corresponding to the MAC PDU1 is 1, the physical channel priority is 2, and if the target priority corresponding to the MAC PDU is the maximum priority among the logical channel priority and the physical channel priority, the target priority corresponding to the MAC PDU1 is 2; if the target priority corresponding to a MAC PDU is the sum of the logical channel priority and the physical channel priority, the target priority corresponding to MAC PDU1 is 3.
Thus, in the embodiment of the present invention, in a case that the physical layer of the ue receives the first MAC PDU first and then receives the second MAC PDU, the first MAC PDU or the second MAC PDU is transmitted for specifying the target priority, and optionally, the method further includes:
and the physical layer of the user equipment receives the target priority of the first MAC PDU and the target priority of the second MAC PDU when receiving the first MAC PDU and the second MAC PDU.
Wherein the target priority may be transmitted to the physical layer along with the corresponding MAC PDU. Of course, it can also be transmitted separately from the MAC PDU.
Alternatively, the transmission of the target priority may be interacted between the MAC layer and the physical layer (PHY) through MAC CE, DCI, or other indication signaling.
Optionally, in this embodiment, the method further includes:
and sending capability information to network side equipment, wherein the capability information indicates that the user equipment supports interlayer priority negotiation.
That is, the user equipment may perform automatic retransmission or new transmission of the MAC PDU. And the network side equipment can receive the retransmitted or newly transmitted MAC PDU after knowing that the user equipment retransmits or newly transmits the MAC PDU through receiving the capability information.
Optionally, in this embodiment, the first MAC PDU selects a first physical channel transmission, and the second MAC PDU selects a second physical channel transmission;
wherein a duration of the first physical channel and a duration of the second physical channel at least partially overlap.
Specifically, the first physical channel and the second physical channel may be implemented as:
a PUSCH with an uplink grant and a PUSCH with another uplink grant;
the PUSCH duration of the uplink grant and the PUSCH of the uplink configuration grant;
a PUSCH with uplink configuration authorization and another PUSCH with uplink configuration authorization;
PUSCH of uplink authorization and PUCCH carrying SR, CSI or HARQ information;
and the uplink configures the authorized PUSCH and the PUCCH carrying the SR, CSI or HARQ information.
Of course, the first physical channel and the second physical channel adopt different combinations, and may also be exchanged with each other, for example, the first physical channel is a PUSCH authorized for uplink, and the second physical channel is a PUSCH authorized for uplink configuration.
It should be noted that, in this embodiment, the MAC layer may also send the MAC PDU or the target priority to the corresponding identified HARQ process, which is not described herein again.
In summary, in the method of the embodiment of the present invention, the MAC layer generates two MAC PDUs and sends them to the physical layer of the lower layer, where the MAC PDU with higher logical channel priority is sent after the MAC PDU with lower logical channel priority. And the physical layer can trigger retransmission or new transmission of the MAC PDU with higher logical channel priority by sending the first information to the MAC layer under the condition that the MAC PDU with lower logical channel priority is transmitted, so that the effective transmission of the MAC PDU is ensured. On the other hand, the physical layer can guarantee the transmission of the MAC PDU with higher priority based on the redefined target priority under the condition that two MAC PDUs are not transmitted, and then trigger the retransmission or new transmission of the other MAC PDU. Therefore, the problem of inter-layer data priority conflict is effectively solved.
As shown in fig. 2, a processing method for data transmission according to an embodiment of the present invention is executed by a user equipment, and includes:
step 201, after sending a first MAC PDU, the MAC layer of the ue sends a second MAC PDU, where the priority of a logical channel corresponding to the first MAC PDU is lower than the priority of a logical channel corresponding to the second MAC PDU;
step 202, receiving first information sent by a physical layer of the ue when the first MAC PDU is transmitted but the second MAC PDU is not transmitted, where the first information is used to indicate retransmission or new transmission of the second MAC PDU.
In this way, the MAC layer performs retransmission or new transmission of the second MAC PDU upon receiving the first information, in a case where the first MAC PDU is transmitted and then the second MAC PDU is transmitted. The problem of inter-layer data priority conflict is effectively solved.
Optionally, the method further comprises:
and receiving second information sent by the physical layer of the user equipment after the first MAC PDU or the second MAC PDU is transmitted according to a target priority, wherein the second information is used for indicating retransmission or new transmission of the MAC PDU which is not transmitted, and the value of the target priority is a common priority value between the physical layer and the MAC layer.
That is, for the received second information, retransmission or new transmission of the untransmitted MAC PDU is performed, and at this time, the untransmitted MAC PDU is the MAC PDU with the lower target priority among the first MAC PDU and the second MAC PDU.
Optionally, the target priority is a maximum priority of a logical channel priority and a physical channel priority, or a sum of the logical channel priority and the physical channel priority.
Optionally, the method further comprises:
and when the MAC layer of the user equipment sends the first MAC PDU and the second MAC PDU, sending the target priority of the first MAC PDU and the target priority of the second MAC PDU.
