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.

Scheduling data transmission by medium access control (MAC) layer in a mobile network

A method for determining padding compatibility is disclosed. A determination is made of a number of protocol data units (PDUs) for a logical channel mapped to a transport channel such that, for a logical channel allowing segmentation, calculate n wherein n=service data unit size/transport block size (SDU size/TB size), and on a condition that n is an integer, setting the number of PDUs=n.

A method for use by a MAC common channel of an RNC to select a transport format combination (TFC) whereby a candidate set of TFCs is selected, and a TFC is chosen from the set of TFCs according to selection criteria.

A method and strategy for transport format combination (TFC) selection and related algorithms in wireless communications. The method provides procedures used by the MAC layer in both the UE and the RNC to schedule data transmission. In the inventive method, each time the maximum transmit power is reached in a time slot, the physical layer will send a notification to the MAC layer, including the time slot number where maximum power was reached. The invention provides a low cost method and algorithm avoiding the need for the MAC to determine the power needed by each TFC in each time slot.
