Embodiment Construction

[0082] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0083] For ease of understanding, the implementation environment involved in each embodiment of the present disclosure is briefly introduced first.

[0084] In LTE, when the sender sends data to the receiver, please refer to figure 1 , the RLC layer at the sending end can receive the SDU packet from the PDCP layer, and since the RLC layer and the MAC layer interact through the PDU pac...

Abstract

The disclosure discloses a method and device for generating a PDU packet, belonging to the technical field of mobile communication. The method includes: obtaining a service data unit SDU packet; processing the SDU packet according to a preset data packet size; generating a data packet header and a data segment of the PDU packet according to the processing result, and the data packet header and the data segment constitute a PDU packet; wherein, the data packet header Omitting the segment in indicates that the FI field and the RF field include preset fields. The preset fields include: fields other than the FI field and RF field redefined in common data packet headers, or the newly added target field, the newly added The field length of the target field is less than the total length of the FI field and the RF field; it solves the problem that the data header of the PDU packet generated in the related art occupies a large overhead, and can directly omit the FI field or omit the FI field while omitting the FI field. A target field with a shorter length is added, thereby reducing the length of the packet header and saving the overhead of the packet header.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, in particular to a method and device for generating a PDU packet. Background technique [0002] In LTE (Long Term Evolution, long-term evolution), the RLC layer (radio link control, radio link control) is between the PDCP (Packet Data Convergence Protocol, packet data convergence protocol) layer and the MAC (Media Access Control, medium access control) layer During the period, the data packet exchanged between the RLC layer and the PDCP layer is called an SDU (Service Data Unit, service data unit) packet, and the data packet exchanged between the RLC layer and the MAC layer is called a PDU (Packet Data Unit, protocol data unit) Bag. [0003] In actual implementation, the MAC layer will specify the size of the PDU packet. Usually, the size of the SDU packet received by the RLC layer is not equal to the size of the PDU packet specified by the MAC layer. Therefore, the RLC lay...
