Problems solved by technology

The data on each logical channel changes dynamically. In the current related technology, it may happen that the data with low logical channel priority of this target UE is sent, but the data with high logical channel priority of other target UEs is not sent. The situation, resulting in QoS can not be guaranteed

example 1

[0164] When the network configures the logical channel priority by broadcasting, the logical channel priority of the logical channel corresponding to the SL-DRB and SL-SRB is a fixed value. The data on each logical channel changes dynamically. According to the current LCP process, when the logical channel priority of the DRB is lower than the logical channel priority of the SRB, the UE will preferentially select the logical channel corresponding to the SRB, and then send the target UE The data of other logical channels is sent in MAC PDU. It may happen that data with low logical channel priority of the target UE is sent, but data with high logical channel priority of other UEs is not sent, resulting in that QoS cannot be guaranteed.

[0165] When the UE MAC receives a direct link transmission permission resource, it selects the highest logical The logical channel of the channel priority, and then select the layer 2 identifier of the corresponding target UE.

[0166] In all l...

[0168] The UEx establishes a connection with UE1, the layer 2 identifier of UE1 is 000, and the following logical channels are configured for the data to be received by UE1. The UEx here is the aforementioned first UE.

[0169] SL-SRB1 corresponds to LCH0, and the logical channel priority is 1;

[0170] SL-SRB2 corresponds to LCH1, and the logical channel priority is 3;

[0171] SL-DRB1 corresponds to LCH2, and the logical channel priority is 0;

[0172] SL-DRB2 corresponds to LCH3, and the logical channel priority is 2.

[0173] The UEx establishes a connection with UE2, the layer 2 identifier of UE2 is 001, and the following logical channels are configured for the data to be received by UE2.

[0174] SL-SRB1 corresponds to LCH5, and the logical channel priority is 4; SL-SRB2 corresponds to LCH6, and the logical channel priority is 1;

[0175] SL-DRB1 corresponds to LCH7, and the logical channel priority is 1; SL-DRB2 corresponds to LCH8, and the logical channel priority ...

Abstract

The embodiment of the invention discloses a data processing method and device, communication equipment and a storage medium. The information processing method applied to first UE can comprise the following steps: determining second UE according to logic channel priorities of logic channels corresponding to direct link data radio bearers (SL-DRBs) and / or direct link signaling radio bearers (SL-SRBs) of to-be-sent data; determining a media access control MAC protocol data unit PDU for sending to the second UE, wherein the MAC PDU comprises an MAC PDU and an MAC protocol data unit, and determining to-be-sent data in one or more SL-RBs according to the logic channel priority of the logic channel corresponding to the SL-RB of the second UE, the SL-RB of the second UE comprising: an SL-DRB of the second UE and / or a signaling radio bearer SL-SRB of the second UE.

Description

technical field [0001] The embodiments of the present application relate to the field of wireless communication but are not limited to the field of wireless communication, and in particular, relate to a data processing method and device, a communication device, and a storage medium. Background technique [0002] In the fourth generation mobile communication (4th, 4G) era, in order to support direct communication between user equipment (User Equipment, UE) and UE, a direct link (sidelink, SL) communication manner is introduced. The protocol stack of the direct link communication method can be as follows: figure 1 As shown, the interface between UEA and UEB is PC-5U. The transmission of the direct link is addressed through the source identifier and target identifier of the radio access control (Media Access Control, MAC) layer, and no connection needs to be established before the transmission. There is only a data radio bearer (Data Radio Bearer, DRB) on the direct link, whi...
