Abstract

The embodiment of the invention discloses a method and equipment for transmitting an MAC PDU (Media Access Control Protocol Data Unit) of an SL (Secondary Link), which are used for improving the transmission flexibility of the MAC PDU. The method comprises the steps that an MAC PDU is generated, the MAC PDU comprises at least two MAC SDUs, and the source address and / or the target address of at least one MAC SDU in the MAC SDUs are / is different from those of other MAC SDUs; and the MAC PDU is sent. The embodiment of the invention also discloses an SL MAC PDU transmission method and equipment.

Description

technical field [0001] The embodiment of the present application relates to the communication field, and in particular to a side link (SideLink, SL for short, or translated as side link, side link, side link, etc.) media access control protocol data unit (MAC PDU) transmission method and equipment. Background technique [0002] The Long Term Evolution (LTE) system supports SL transmission, that is, data transmission can be directly performed on a physical layer between terminal devices. [0003] The New Radio or New Radio (NR) system will support a more advanced SL transmission design to support more comprehensive types of services. In related technologies, the SL MAC PDU only supports service transmission from one source address to one destination address, and the flexibility of MAC PDU transmission is poor. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a SL MAC PDU transmission method and device, so as to improv...
