US 9,867,208 B2 · Scheduling data transmission by medium access control (MAC) layer in a mobile network

Abstract

A method and apparatus for producing medium access control (MAC) protocol data units (PDUs) are disclosed. A controller may, on a Transmission Time Interval (TTI) basis, select a size of a MAC service data unit (SDU) for each of a plurality of logical channels based on information provided by a MAC layer. The controller may then provide a respective first value for each logical channel. Further, the controller may select logical channels for a MAC PDU based on a respective priority of each of the logical channels and on the respective first value of each of the logical channels being greater than zero. Also, the controller may multiplex the MAC SDUs of the selected logical channels to produce the MAC PDU. In addition, the controller may provide a transport block for transmission based on the MAC PDU. The controller and a transmitter may then transmit the provided transport block.

Dependent claims

A user equipment (UE) comprising:

a transmitter;
and
a controller operatively coupled to the transmitter, the controller configured to, on a transmission time interval (TTI) basis, select a size of a radio-link control (RLC) protocol data unit (PDU) for each of a plurality of logical channels based on information provided by a medium access control (MAC) layer;
the controller configured, for each logical channel, to provide a respective first value;
the controller configured to select logical channels for a MAC PDU based on a respective priority of each of the logical channels and on the respective first value of each of the logical channels being greater than zero;
the controller configured to multiplex MAC service data units (SDUs) of the selected logical channels to produce the MAC PDU, wherein the MAC SDUs respectively correspond to the sized RLC PDUs;
the controller configured to provide a transport block for transmission based on the MAC PDU;
and
the controller and the transmitter configured to transmit the provided transport block.
