Embodiment 1

[0032] According to an embodiment of the present invention, a method for sending a PDU is firstly provided.

[0033] image 3 shows the flow of the PDU sending method according to Embodiment 1 of the method of the present invention, as image 3 As shown, the PDU sending method according to Embodiment 1 of the method of the present invention mainly includes the following steps (step S302-step S306):

[0034] Step S302, the sender's RLC receives multiple consecutive PDUs from the PDCP, wherein each of the multiple PDUs carries: the data information of the PDU and the header information of the SN including the PDU;

[0035] Step S304, the RLC carries each of the above PDUs in one or more RLC messages, wherein the SNs of the PDUs carried in each RLC message are connected, and each RLC message only carries the SN of one PDU;

[0036] Step S306, the RLC sends the one or more RLC messages to the receiver.

[0037] Preferably, the header of each RLC message in one or more RLC messa...

Embodiment 2

[0090] According to an embodiment of the present invention, a method for receiving a PDU is also provided, and the method for receiving a PDU can be used in conjunction with the above method for sending a PDU.

[0091] Figure 6 Shows the flow of the PDU receiving method according to the second method embodiment of the present invention, as Figure 6 As shown, the receiving method of the PDU according to the second embodiment of the method of the present invention mainly includes the following steps (step S602-step S608):

[0092] Step S602, the receiver's RLC receives a plurality of consecutive RLC messages from the sender, wherein each RLC message carries the SN of a PDU and at least one PDU, and each PDU includes: data information and other Including the header information of SN;

[0093] Step S604, the RLC parses the received multiple RLC messages, and obtains the SN carried in each RLC message and the data information of each PDU and the header information not including...

Abstract

The invention discloses sending / receiving method and device of PDU (Protocol Data Unit), wherein the sending method of the PDU comprises the following steps that an RLC (Radio Link Control) of a sending party receives a plurality of PDUs from a PDCP, and each PDU comprises data information and header information including a sequence number SN; the RLC carries the PDUs in one or more RLC messages, wherein SN of the carried PDU of each RLC message is continuous and each RLC message only carries SN of one PDU; and the RLC sends one or more RLC messages to a receiving party. The invention can reduce occupied system resource in the process of PDU transmission and enhance the transmission efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a protocol data unit (PDU) sending / receiving method and device. Background technique [0002] Long Term Evolution (LTE for short) is the latest wireless communication system of the 3rd Generation Partnership Project (3GPP for short), which improves and enhances the 3G air access technology. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM for short) and Multiple Input Multiple Output (MIMO for short) as the basic technologies for its wireless network evolution. The main performance goals include: providing a peak rate of 100Mbps downlink and 50Mbps uplink in a 20MHz spectrum bandwidth; improving the performance of cell edge users; increasing cell capacity; reducing system delay; supporting 100km radius cell coverage; Access services greater than 100kbps; support paired or unpaired spectrum, and flexible configuration of bandwidth, etc. [0003] LTE air interface pro...
