However, in the prior art, since there is no RN, there is no multiplexing of dedicated data of multiple UEs in the same MAC PDU, and there is no relevant information about the UE identity in the MAC PDU
In the LTE-A system

Embodiment Construction

[0087] The embodiment of the present invention proposes that the MAC layer of the sending end obtains the MAC SDU to be sent, and generates a MAC CE; the MAC layer of the sending end assembles a MAC PDU according to the MAC SDU and the MAC CE, and the MAC PDU carries The attribution identifier corresponding to the MAC SDU and the MAC CE; the sending end sends the MAC PDU to the receiving end, so that the MAC layer of the receiving end according to the MAC SDU carried in the MAC PDU and the The attribution identifier corresponding to the MAC CE determines the attribution of the MAC SDU and the MAC CE.

[0088] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of o...

Abstract

The embodiment of the invention discloses a method, a system and a device for transmitting an MAC (media access control) PDU (protocol data unit). The method comprises that: an MAC layer at a transmitting end acquires an MAC SDU (service data unit) to be transmitted and generates MAC CE (control element); the MAC layer of the transmitting end assembles the MAC SDU and the MAC CE into the MAC PDU, wherein the MAC PDU carries attribution identifiers corresponding to the MAC SDU and the MAC CE; and the transmitting end transmits the MAC PDU to a receiving end, so that an MAC layer at the receiving end determines the attributions of the MAC SDU and the MAC CE according to the attribution identifiers corresponding to the MAC SDU and the MAC CE carried in the MAC PDU. Therefore, the data at each terminal is distinguished when the data of a plurality of terminals is multiplexed in the same MAC PDU, and the data is transmitted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for sending a MAC PDU. Background technique [0002] In the LTE (Long-Term Evolution, long-term evolution) system, such as figure 1 As shown, the interface between the eNB (Evolved Node B, evolved base station) and UE (User Equipment, terminal) is the Uu interface, and the MAC PDU is transmitted through the Uu interface after being processed at the physical layer. For dedicated data (except broadcast, paging, random access response, MBMS (Multimedia Broadcast / Multicast Service, multimedia broadcast / multicast service), etc.), whether it is uplink or downlink, the data in one MAC PDU is for one For the UE, the identifier of the UE is carried in a PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel), that is, there is no situation where the dedicated data of multiple UEs are multiplexed and transmitted in one MAC PD...
