Abstract
The present disclosure relates to a method of transmitting a Medium Access Control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of based on a first Medium Access Control (MAC) control element (CE) being triggered, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted; receiving a control UL grant from the network; constructing a MAC protocol data unit (PDU) including the first MAC CE; and transmitting the MAC PDU using the control UL grant.
Claims8
A method of transmitting a Medium Access Control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system, the method comprising:
- based on a first MAC control element (CE) becoming available for transmission, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted;
- receiving a control UL grant from the network, wherein a second MAC CE becomes available for transmission before receiving the control UL grant;
- multiplexing at least one of the first and second MAC CEs in a MAC protocol data unit (PDU), wherein based on one of the first and second MAC CEs being multiplexed in the MAC PDU, the MAC PDU includes information indicating an amount of a remaining MAC CE;
- and
- transmitting the MAC PDU according to the control UL grant.
A user equipment (UE) in a wireless communication system, the UE comprising:
- at least one processor;
- and
- at least one computer memory storing instructions that, when executed by the at least one processor, cause the UE to perform operations comprising:
- based on a first Medium Access Control (MAC) control element (CE) becoming available for transmission, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted;
- receiving a control UL grant from the network, wherein a second MAC CE becomes available for transmission before receiving the control UL grant;
- multiplexing at least one of the first and second MAC CEs in a MAC protocol data unit (PDU), wherein based on one of the first and second MAC CEs being multiplexed in the MAC PDU, the MAC PDU includes information indicating an amount of a remaining MAC CE;
- and
- transmitting the MAC PDU according to the control UL grant.
An apparatus for a user equipment (UE), the apparatus comprising:
- at least one processor;
- and
- at least one computer memory storing instructions that, when executed by the at least one processor, cause the UE to perform operations comprising:
- based on a first Medium Access Control (MAC) control element (CE) becoming available for transmission, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted;
- receiving a control UL grant from the network, wherein a second MAC CE becomes available for transmission before receiving the control UL grant;
- multiplexing at least one of the first and second MAC CEs in a MAC protocol data unit (PDU), wherein based on one of the first and second MAC CEs being multiplexed in the MAC PDU, the MAC PDU includes information indicating an amount of a remaining MAC CE;
- and
- transmitting the MAC PDU according to the control UL grant.
A non-transitory computer readable storage medium comprising program instructions that, when executed by at least one processor, cause a user equipment (UE) to perform operations comprising:
- based on a first Medium Access Control (MAC) control element (CE) becoming available for transmission, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted;
- receiving a control UL grant from the network, wherein a second MAC CE becomes available for transmission before receiving the control UL grant;
- multiplexing at least one of the first and second MAC CEs in a MAC protocol data unit (PDU), wherein based on one of the first and second MAC CEs being multiplexed in the MAC PDU, the MAC PDU includes information indicating an amount of a remaining MAC CE;
- and
- transmitting the MAC PDU according to the control UL grant.
