Abstract
A first terminal device has first data to be transmitted on a sidelink and has second data to be transmitted on an uplink. The first terminal device performs medium access control MAC protocol data unit PDU assembly on the first data or does not perform MAC PDU assembly on the first data based on a result of comparison between a transmission priority of the first data and a transmission priority of the second data.
Claims20
A method applied to a first terminal device or a chip of the first terminal device, the method comprising:
- obtaining a specified quantity of sending times of sending a medium access control (MAC) protocol data unit (PDU) corresponding to first data, wherein the first data is to be sent by the first terminal device to a second terminal device on a sidelink, and the sidelink is a direct wireless communication link between the first terminal device and the second terminal device;
- and
- sending, using a transmission resource, the MAC PDU on the sidelink based on the specified quantity of sending times, wherein the transmission resource is any transmission resource in periodic resources of the first terminal device,
- wherein obtaining the specified quantity of sending times of sending the MAC PDU corresponding to the first data comprises:
- determining the specified quantity of sending times based on a quality of service parameter corresponding to the MAC PDU, and based on a correspondence between the specified quantity of sending times and the quality of service parameter corresponding to the MAC PDU.
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory memory storing instructions for execution by the at least one processor;
- wherein, when executed by the at least one processor, the instructions cause the apparatus to perform operations comprising:
- obtaining a specified quantity of sending times of sending a medium access control (MAC) protocol data unit a (PDU) corresponding to first data, wherein the first data is to be sent by the apparatus to a second terminal device on a sidelink, and the sidelink is a direct wireless communication link between a first terminal device and the second terminal device;
- and
- sending the MAC PDU based on the specified quantity of sending times using a transmission resource, wherein the transmission resource is any transmission resource in periodic resources of the apparatus, wherein obtaining the specified quantity of sending times of sending the MAC PDU corresponding to the first data comprises:
- determining the specified quantity of sending times based on a quality of service Parameter corresponding to the MAC PDU, and based on a correspondence between the specified quantity of sending times and the quality of service parameter corresponding to the MAC PDU.
A non-transitory computer readable medium with computer readable instructions stored thereon, wherein the instructions, when executed by at least one processor, cause the at least one processor to perform the steps of:
- obtaining a specified quantity of sending times of sending a medium access control (MAC) protocol data unit a (PDU) corresponding to first data, wherein the first data is to be sent to a second terminal device on a sidelink, and the sidelink is a direct wireless communication link between a first terminal device and the second terminal device;
- and
- sending the MAC PDU based on the specified quantity of sending times using a transmission resource, wherein the transmission resource is any transmission resource in periodic resources of an apparatus, wherein obtaining the specified quantity of sending times of sending the MAC PDU corresponding to the first data comprises:
- determining the specified quantity of sending times based on a quality of service parameter corresponding to the MAC PDU, and based on a correspondence between the specified quantity of sending times and the quality of service parameter corresponding to the MAC PDU.
