Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a data transmission processing method, device and equipment. BACKGROUND

[0002] When the data of the industrial internet is non-periodic and occasional, the base station cannot perceive the arrival of the data in advance. Due to the ultra-low latency requirement of the industrial internet of things, the data should be carried by the uplink configured grant. Therefore, the data carried by the base station dynamic scheduling (such as the physical uplink shared channel (PUSCH) scheduled by the downlink control information (DCI)) and the data carried by the uplink configured grant may conflict. Or, due to the consideration of saving resources or matching the arbitrary period of the service, the physical resources of multiple configured grants may be partially overlapped, so the data of multiple configured grants may also conflict.

[0003] In the prior art, the priority of transmission is introduced to solve the conflict of data. However, the priority order designed by the physical layer and the media access control (MAC) layer for the data in the user equipment (UE) is independently applied in the protocol of the layer. If the priority configurations of the physical layer and the MAC layer are inconsistent, the data may not be transmitted in time or need to be retransmitted, thereby causing a long transmission delay.

[0078] To make the technical problems, technical solutions and advantages of the present application clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0079] It should be understood that the term "one embodiment" or "an embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0080] In various embodiments of the present application, it should be understood that the magnitude of the serial number of the following processes does not mean the order of execution, the execution order of the processes should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0081] In addition, the terms "system" and "network" are often used interchangeably herein.

[0082] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0083] As shown in FIG. 1, a data transmission processing method of an embodiment of the present application is executed by a user equipment, and includes the following steps. Figure 1

[0084] Step 101, when the physical layer of the user equipment receives a second MAC PDU after receiving a first MAC PDU, and the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU,

[0085] If the first MAC PDU has been transmitted, the first information is sent to the MAC layer of the user equipment, the first information is used to indicate the retransmission or new transmission of the second MAC PDU;

[0086] If the first MAC PDU has not been transmitted, the first MAC PDU or the second MAC PDU is transmitted according to the target priority, the value of the target priority is the common priority value between the physical layer and the MAC layer.

[0087] ​In this way, in the case that the physical layer of the user equipment receives a first MAC PDU with a lower logical channel priority sent by the MAC layer first and then receives a second MAC PDU with a higher logical channel priority sent by the MAC layer, if the physical layer has transmitted the first MAC PDU, the first information indicating 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 the target priority, where the value of the target priority is a common priority value between the physical layer and the MAC layer. In this way, the priority conflict between the physical layer and the MAC layer during data transmission can be solved, the transmission delay can be avoided, and the transmission efficiency can be improved.

[0088] It should be known that the retransmission or new transmission in the embodiment can be automatic retransmission or new transmission of the MAC PDU, or can be scheduled retransmission or new transmission of the MAC PDU.

[0089] Of course, the physical layer of the user equipment will retransmit or newly transmit the second MAC PDU after receiving the first information. In this way, both the first MAC PDU and the second MAC PDU can be transmitted in the physical layer, and the transmission requirement can be met.

[0090] The target priority is not the logical channel priority, and the value of the target priority will be used as the value of the common priority between the physical layer and the MAC layer. When the physical layer receives the first MAC PDU first and then receives the second MAC PDU, the physical layer compares the value of the target priority of the first MAC PDU with the value of the target priority of the second MAC PDU to determine whether to transmit the first MAC PDU or the second MAC PDU.

[0091] In this way, in the case that the physical layer of the user equipment receives a first MAC PDU with a lower logical channel priority sent by the MAC layer first and then receives a second MAC PDU with a higher logical channel priority sent by the MAC layer, if the physical layer has transmitted the first MAC PDU, the first information indicating 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 the target priority, where the value of the target priority is a common priority value between the physical layer and the MAC layer. In this way, the priority conflict between the physical layer and the MAC layer during data transmission can be solved, the transmission delay can be avoided, and the transmission efficiency can be improved.

[0092] In addition, for the MAC PDU with a lower target priority and not transmitted by the physical layer, the method in the embodiment further comprises:

[0093] After transmitting the first MAC PDU or the second MAC PDU according to the target priority, the second information is sent to the MAC layer of the user equipment, where the second information is used to indicate retransmission or new transmission of the MAC PDU not transmitted.

[0094] Therefore, after receiving the second information, the physical layer of the user equipment can transmit the MAC PDU which is not transmitted due to the lower target priority in the retransmitted or newly transmitted first MAC PDU and second MAC PDU. The transmission of the first MAC PDU and the second MAC PDU in the physical layer is also realized, and the transmission requirement is met.

[0095] Optionally, in the 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.

[0096] That is, in the face of the conflict between the priorities of the layers, the target priority based on which the physical layer transmits 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. Of course, the specific value of the target priority is pre-configured, such as inter-layer negotiation.

[0097] Suppose that the logical channel priority corresponding to the MAC PDU1 is 1, and the physical channel priority is 2. If the target priority corresponding to the MAC PDU is the maximum priority of 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 the MAC PDU is the sum of the logical channel priority and the physical channel priority, the target priority corresponding to the MAC PDU1 is 3.

[0098] Therefore, in the embodiment of the application, in the case that the physical layer of the user equipment receives the first MAC PDU first and then receives the second MAC PDU, to determine the target priority and then transmit the first MAC PDU or the second MAC PDU, the method further comprises the following steps:

[0099] 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.

[0100] The target priority can be transmitted to the physical layer together with the corresponding MAC PDU. Of course, the target priority can also be transmitted independently from the MAC PDU.

[0101] Optionally, the transmission of the target priority can be realized by MAC CE, DCI or other indication signaling between the MAC layer and the physical layer (PHY).

[0102] Optionally, the method further comprises the following steps:

[0103] The capability information is transmitted to the network side device, and the capability information indicates that the user equipment supports inter-layer priority negotiation.

[0104] That is, the user equipment can perform automatic retransmission or new transmission of the MAC PDU. After the network side equipment learns the retransmission or new transmission of the MAC PDU by the user equipment through receiving the capability information, the network side equipment can receive the retransmitted or newly transmitted MAC PDU.

[0105] Optionally, in the embodiment, the first MAC PDU is transmitted through a first physical channel, and the second MAC PDU is transmitted through a second physical channel.

[0106] The duration of the first physical channel and the duration of the second physical channel at least partially overlap.

[0107] Specifically, the first physical channel and the second physical channel can be implemented as:

[0108] an uplink granted PUSCH and another uplink granted PUSCH;

[0109] an uplink granted PUSCH and an uplink configured grant PUSCH;

[0110] an uplink configured grant PUSCH and another uplink configured grant PUSCH;

[0111] an uplink granted PUSCH and a PUCCH carrying SR, CSI or HARQ information;

[0112] an uplink configured grant PUSCH and a PUCCH carrying SR, CSI or HARQ information.

[0113] Of course, the above-mentioned first physical channel and second physical channel can also be exchanged with each other in combination of different implementations, such as the first physical channel being an uplink granted PUSCH and the second physical channel being an uplink configured grant PUSCH.

[0114] It should be noted that in the embodiment, the MAC layer can also send a MAC PDU or a target priority to a corresponding identified HARQ process, which will not be described here.

[0115] In summary, the method of the embodiment of the present application generates two MAC PDUs in the MAC layer, and sends them to the physical layer in the lower layer, wherein the MAC PDU with a higher logical channel priority is sent after the MAC PDU with a lower logical channel priority. The physical layer can trigger the retransmission or new transmission of the MAC PDU with a higher logical channel priority by sending the first information to the MAC layer in the case that the MAC PDU with a lower logical channel priority has been transmitted, so as to ensure the effective transmission of the MAC PDU. On the other hand, the physical layer can ensure the transmission of the MAC PDU with a higher priority based on the redefined target priority in the case that neither of the two MAC PDUs has been transmitted, and then trigger the retransmission or new transmission of the other MAC PDU. In this way, the problem of the conflict between the data priorities of different layers is effectively solved.

[0116] As shown in Figure 2 the processing method of the data transmission of the embodiment of the present application is executed by a user equipment, and includes the following steps.

[0117] Step 201, the MAC layer of the user equipment sends a second MAC PDU after sending a first MAC PDU, wherein the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU.

[0118] Step 202, the physical layer of the user equipment receives the first information sent by the physical layer in the case that the first MAC PDU has been transmitted but the second MAC PDU has not been transmitted, wherein the first information is used to indicate the retransmission or new transmission of the second MAC PDU.

[0119] In this way, the MAC layer retransmits or newly transmits the second MAC PDU in the case that the first MAC PDU is sent and then the second MAC PDU is sent, and the first information is received. The problem of the conflict between the data priorities of different layers is effectively solved.

[0120] Optionally, the method further includes the following steps.

[0121] Step 203, the physical layer of the user equipment receives the second information sent by the physical layer after the first MAC PDU or the second MAC PDU is transmitted according to the target priority, wherein the second information is used to indicate the retransmission or new transmission of the MAC PDU which has not been transmitted, and the value of the target priority is the common priority value between the physical layer and the MAC layer.

[0122] That is to say, the retransmission or new transmission of the MAC PDU which has not been transmitted is performed according to the received second information, and at this time, the MAC PDU which has not been transmitted is the MAC PDU with a lower target priority among the first MAC PDU and the second MAC PDU.

[0123] Optionally, the target priority is a maximum priority of the logical channel priority and the physical channel priority, or a sum of the logical channel priority and the physical channel priority.

[0124] Optionally, the method further comprises:

[0125] The MAC layer of the user equipment transmits the target priority of the first MAC PDU and the target priority of the second MAC PDU when transmitting the first MAC PDU and the second MAC PDU.

[0126] It should be noted that the MAC layer is implemented in cooperation with the physical layer of the previous embodiment, and the implementation manner in the above embodiment is applicable to the method and can achieve the same technical effects.

[0127] As shown in Figure 3 An embodiment of the present application provides a processing apparatus for data transmission, comprising:

[0128] The first transmission processing module 310 is configured to, when the physical layer of the user equipment receives the second MAC PDU after receiving the first MAC PDU, and the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU,

[0129] If the first MAC PDU has been transmitted, the first information is transmitted to the MAC layer of the user equipment, and the first information is used to indicate retransmission or new transmission of the second MAC PDU.

[0130] If the first MAC PDU has not been transmitted, the first MAC PDU or the second MAC PDU is transmitted according to a target priority, and the value of the target priority is a common priority value between the physical layer and the MAC layer.

[0131] Optionally, the apparatus further comprises:

[0132] The second transmission processing module is configured to, after transmitting the first MAC PDU or the second MAC PDU according to the target priority, transmit second information to the MAC layer of the user equipment, and the second information is used to indicate retransmission or new transmission of the MAC PDU that has not been transmitted.

[0133] Optionally, the target priority is a maximum priority of the logical channel priority and the physical channel priority, or a sum of the logical channel priority and the physical channel priority.

[0134] Optionally, the apparatus further comprises:

[0135] The third transmission processing module is configured to receive, by a physical layer of the user equipment, a target priority of the first MAC PDU and a target priority of the second MAC PDU when receiving the first MAC PDU and the second MAC PDU.

[0136] Optionally, the apparatus further comprises:

[0137] The capability information sending module is configured to send capability information to a network side device, wherein the capability information indicates that the user equipment supports inter-layer priority negotiation.

[0138] Optionally, the first MAC PDU is selected to be transmitted through a first physical channel, and the second MAC PDU is selected to be transmitted through a second physical channel.

[0139] The duration of the first physical channel and the duration of the second physical channel at least partially overlap.

[0140] In the case that the apparatus first receives a first MAC PDU with a lower logical channel priority sent by a MAC layer, and then receives a second MAC PDU with a higher logical channel priority sent by the MAC layer, if the physical layer has transmitted the first MAC PDU, the apparatus sends first information indicating retransmission or new transmission of the second MAC PDU to the MAC layer; if the physical layer has not transmitted the first MAC PDU, the apparatus transmits 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 the physical layer and the MAC layer. In this way, the priority conflict between the physical layer and the MAC layer during data transmission can be solved, the transmission delay can be avoided from being too long, and the transmission efficiency can be improved.

[0141] The apparatus applies the method performed by the physical layer of the user equipment, and the implementation manners of the embodiments of the method are applicable to the apparatus, and the same technical effects can be achieved.

[0143] The sending module 410 is configured to send, by a MAC layer of the user equipment, a second MAC PDU after sending a first MAC PDU, wherein the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU.

[0150] In the case that the MAC layer transmits the first MAC PDU and then transmits the second MAC PDU, for the received first information, the second MAC PDU is retransmitted or newly transmitted. Of course, for the received second information, the untransmitted MAC PDU is retransmitted or newly transmitted, and at this time, the untransmitted MAC PDU is the MAC PDU with the lower target priority in the first MAC PDU and the second MAC PDU.

[0151] It should be noted that the apparatus applies the method executed by the MAC layer of the user equipment, and the implementation manners of the embodiments of the method are applicable to the apparatus, and the same technical effects can be achieved.

[0152] As shown in Figure 5 FIG. 5, a user equipment 500 according to an embodiment of the present application comprises a transceiver 510, wherein the transceiver 510 is configured to:

[0153] when the physical layer of the user equipment receives the second MAC PDU after receiving the first MAC PDU, and the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU,

[0154] if the first MAC PDU has been transmitted, the first information is sent to the MAC layer of the user equipment, the first information being used to indicate retransmission or new transmission of the second MAC PDU;

[0155] If the first MAC PDU is not transmitted, the first MAC PDU or the second MAC PDU is transmitted according to a target priority, a value of the target priority being a common priority value between the physical layer and the MAC layer.

[0156] Optionally, the transceiver is further configured to:

[0157] 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, the second information being used to indicate retransmission or new transmission of the MAC PDU that is not transmitted.

[0158] 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.

[0159] Optionally, the transceiver is further configured to:

[0160] 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.

[0161] Optionally, the transceiver is further configured to:

[0162] The capability information is sent to the network side device, the capability information indicating that the user equipment supports interlayer priority negotiation.

[0163] Optionally, the first MAC PDU is transmitted by selecting a first physical channel, and the second MAC PDU is transmitted by selecting a second physical channel.

[0164] The duration of the first physical channel and the duration of the second physical channel at least partially overlap.

[0165] In the user equipment of the embodiment, when the physical layer first receives the first MAC PDU with a lower logical channel priority sent by the MAC layer, and then receives the second MAC PDU with a higher logical channel priority sent by the MAC layer, if the physical layer has transmitted the first MAC PDU, the first information indicating 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, a value of the target priority being a common priority value between the physical layer and the MAC layer. In this way, the priority conflict between the physical layer and the MAC layer in data transmission can be solved, the transmission delay can be avoided, and the transmission efficiency can be improved.

[0166] A user equipment according to an embodiment of the present invention includes a transceiver, the transceiver being used for:

[0167] After sending the first MAC PDU, the MAC layer of the user equipment sends the second MAC PDU, and the logical channel priority corresponding to the first MAC PDU is lower than the logical channel priority corresponding to the second MAC PDU.

[0168] The user equipment receives a first message sent by its physical layer when the first MAC PDU has been transmitted but the second MAC PDU has not been transmitted. The first message is used to indicate whether the second MAC PDU should be retransmitted or retransmitted.

[0169] Optionally, the transceiver is further configured to:

[0170] The user equipment receives second information sent by the physical layer after the first MAC PDU or the second MAC PDU is transmitted according to a target priority. The second information is used to indicate the retransmission or retransmission of the untransmitted MAC PDU. The target priority value is a common priority value between the physical layer and the MAC layer.

[0171] Optionally, the target priority is the highest priority among the logical channel priority and the physical channel priority, or the sum of the logical channel priority and the physical channel priority.

[0172] Optionally, the transceiver is further configured to:

[0173] When the MAC layer of the user equipment sends the first MAC PDU and the second MAC PDU, it sends the target priority of the first MAC PDU and the target priority of the second MAC PDU.

[0174] In this user equipment, when the MAC layer sends a first MAC PDU and subsequently a second MAC PDU, upon receiving the first information, it retransmits or retransmits the second MAC PDU. Similarly, upon receiving the second information, it retransmits or retransmits any untransmitted MAC PDUs. In this case, the untransmitted MAC PDU is the one with the lower target priority between the first and second MAC PDUs.

[0176] The transceiver 610 is used to receive and send data under the control of the processor 600.

[0177] Among them, Figure 6 In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 600 and memory represented by memory 620 together.
