Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a data transmission method provided in an embodiment of the present invention, which is used for a receiving end device, and as shown in fig. 1, the data transmission method includes the following steps:
step 101, a medium access control MAC entity of a receiving end device receives a protocol data unit MAC PDU of medium access control, where the MAC PDU includes a service data unit SDU, a radio bearer RB identifier, and a protocol function identifier (Protocol Function Entity ID).
The MAC PDU received by the MAC of the receiving end may be obtained from the terminal or from the network side device. After the receiving end obtains the MAC PDU, the receiving end analyzes the MAC PDU and obtains the RB identification, the protocol function body identification and the SDU from the sub-header of the MAC.
The RB identifier may be an RB number or an RB sequence number; the protocol function body identifier may be a protocol function body number or a protocol function body serial number. The RB identity and the protocol function identity are configured identically by radio resource control (RRC, radio Resource Control) at the network side by RRC signaling. After the configuration is carried out through RRC signaling, the RB identifications and the protocol function identifications of the receiving end equipment and the transmitting end equipment are kept consistent, so that the receiving end equipment and the transmitting end equipment can transmit SDU or data information included by the SDU through the RB.
Step 102: and under the condition that the RB identifier is the identifier of the AI RB, the receiving end equipment transmits the SDU or the data information included by the SDU to the protocol function body corresponding to the protocol function body identifier, and the AI RB is associated with a plurality of protocol function bodies in the receiving end equipment.
The AI RB is a common logical bearer in a User Equipment (UE), and can associate a plurality of protocol functional entities in a receiving end device, and the receiving end device sends an SDU or data information included in the SDU to the outside or sends the data information to other protocol functional entities through the AI RB.
And the receiving terminal equipment analyzes after receiving the MAC PDU to obtain the SDU, the radio bearer RB identifier and the protocol function body identifier included in the MAC PDU. If SDU is SDU of MAC entity of receiving end equipment, then MAC entity carries out subsequent analysis process; and the receiving terminal equipment sends the SDU or the data information contained in the SDU to the protocol function body through the AI RB.
During the data transmission process, the AI RB does not record or transfer the processing information of the receiving end, i.e. does not need to perform interlayer mapping.
In the data transmission method of the embodiment, the MAC entity of the receiving end device receives the MAC PDU, and sends the data information included in the SDU or the SDU to the protocol function corresponding to the protocol function identifier under the condition that the RB identifier is the identifier of the AI RB, through the SDU, the radio bearer RB identifier and the protocol function identifier included in the MAC PDU, and by using the characteristics of the AI RB associated with the plurality of protocol functions, the time required for establishing the plurality of bearers during the data transmission is reduced, thereby reducing the delay of the data transmission.
In one embodiment, the MAC PDU further comprises routing information between the MAC entity and the protocol functionality; transmitting SDU or data information included by SDU to protocol function corresponding to protocol function identification, comprising:
and transmitting the SDU or the data information included by the SDU to a protocol function corresponding to the protocol function identifier according to the routing information.
When the AI RB transmits the SDU or the data information included in the SDU to the protocol function corresponding to the protocol function identifier, in order to ensure the accuracy of transmission, the data information included in the SDU or the SDU is effectively transmitted to the corresponding protocol function, so that the MAC PDU needs to include the routing information between the MAC entity and the protocol function.
That is, in this embodiment, when the receiving end device sends the SDU or the data information included in the SDU to the protocol function corresponding to the protocol function identifier, the receiving end device needs to confirm the transmission path according to the routing information between the MAC entity included in the MAC PDU and the protocol function, so as to effectively transmit the SDU or the data information included in the SDU to the protocol function.
In one embodiment, the sub-header of the MAC PDU carries the AI RB identification.
The MAC PDU comprises a plurality of sub-PDUs, each sub-PDU at least comprises an MAC sub-header, the sub-header of the MAC PDU is set to carry an AI RB identifier, the receiving end equipment analyzes the sub-header of the MAC PDU to obtain the AI RB identifier, and the corresponding AI RB transmits SDU or data information included by the SDU.
In this embodiment, the identifier of the AI RB in the UE is unique, so that the receiving end device can quickly confirm the AI RB in the UE through the AI RB identifier carried by the subheader of the MAC PDU, and then transmit the SDU or the data information included in the SDU through the AI RB.
In one embodiment, the sub-header of the MAC PDU includes a logical channel identification (LCID, logical Channel Identity), which includes an AI RB identification.
In order to realize that the MAC PDU comprises an AI RB identifier and a protocol function body identifier, and directly expands based on the format of the existing MAC PDU, the format structure of the existing MAC PDU is not changed. The MAC PDU format extension is shown in fig. 2, 3 and 4, the existing format is the upper diagram, and the extended format is the lower diagram. In the figure, L indicates the length of the corresponding MAC PDU, F indicates the length of the L field in bytes, E indicates whether there are more fields following the MAC header, R is a reserved bit, and is set to "0".
The AI RB identity AI RB ID is set to a new type ID of LCID, i.e. AI RB and other types of RBs or Logical channels (Logical channels) are collectively numbered, e.g. lcid= … n, at which time the value of AI RB ID is set to a value in the range of 0 … n. Meanwhile, the protocol function body identifier is arranged in the L field, so that the MAC PDU carries the protocol function body identifier.
In this embodiment, by expanding the MAC PDU, the LCID of the MAC PDU may include an AI RB ID and a protocol function identifier, and the receiving end device may transmit the SDU or data information included in the SDU to the protocol function corresponding to the protocol function identifier through the AI RB ID.
In one embodiment, the protocol function identification includes one of:
identification of the protocol function in the receiving end device;
the identity of the packet in which the protocol functionality is located in the receiving end device, and the identity of the protocol functionality in the packet.
The protocol function body identifier is used for identifying the protocol function body in the UE, and the receiving end equipment can confirm the protocol function body through the protocol function body identifier. Since AI RB associates multiple protocol functions, and different protocol functions are all set in the same UE, different protocol functions need to be identified differently by the protocol function identifier.
In this embodiment, the protocol function identifier may be an identifier of the protocol function in the receiving end device, or the protocol function identifier may be an identifier of a packet in which the protocol function is located in the receiving end device and an identifier of the protocol function in the packet, so that the protocol function identifier may be in one-to-one correspondence with the protocol function in the UE.

In this embodiment, the SDU or the data information included in the SDU is set to include AI information, so that the AI information can be quickly transmitted between the network side and the terminal side through the AI RB, and interaction between the UE side and the network side is achieved.
In one embodiment, the protocol functionality includes at least one of:
a Radio Resource Control (RRC) entity, a Service Data Adaptation Protocol (SDAP) entity, a Packet Data Convergence Protocol (PDCP) entity and a Radio Link Control (RLC) entity.
As shown in fig. 5, AI RBs are associated with multiple protocol functions within the UE, and to enable AI RBs to transmit more SDUs or data information comprised by SDUs, AI RBs are associated with different protocol functions within the UE as much as possible. The protocol functional bodies in the UE mainly comprise a Radio Resource Control (RRC) entity, a Service Data Adaptation Protocol (SDAP) entity, a Packet Data Convergence Protocol (PDCP) entity and a Radio Link Control (RLC) entity, and the AI RB and the protocol functional bodies are associated, so that the SDU or the data information contained in the SDU can be effectively transmitted to different protocol functional bodies through the AI RB.
In this embodiment, the protocol functional body radio resource control RRC entity, the service data adaptation protocol SDAP entity, the packet data convergence protocol PDCP entity, and the radio link control RLC entity enable the AI RB to transmit SDUs or data information included in SDUs between the receiving end and different protocol functional bodies, so as to reduce occupation of other bearers by data as much as possible, and effectively reduce delay of data transmission.
Referring to fig. 6, fig. 6 is a flowchart of another data transmission method provided by the embodiment of the present invention, which is executed by a transmitting end device, as shown in fig. 6, the data transmission method includes the following steps:
step 201, a transmitting end device generates a media access control MAC entity to receive a protocol data unit MAC PDU of media access control, where the MAC PDU includes an SDU or data information included in the SDU, a radio bearer RB identifier, and a protocol function identifier.
