초록 ▼

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

대표청구항 ▼

1. A user equipment comprising: a medium access control (MAC) unit configured to provide a plurality of logical channels; wherein each of the logical channels has an associated priority; wherein the MAC unit is further configured to multiplex data of at least one of the plurality of logical channels into a MAC protocol data unit (PDU); wherein the MAC unit is further configured to select, based on a maximum transmission power level, a transport format combination (TFC) associated with the MAC PDU that maximizes transmission of data of a logical channel having a highest priority such that no other TFC that maximizes transmission of highest priority data has a lower bit rate than the selected TFC; wherein the MAC unit is further configured to generate, and transmit, a MAC PDU based on the selected TFC. 2. The user equipment of claim 1 wherein the MAC unit is further configured to multiplex data into the MAC PDU considering a MAC header. 3. The user equipment of claim 1 wherein on a condition that a plurality of logical channels have the highest priority, a logical channel out of the plurality of logical channels is selected randomly. 4. The user equipment of claim 1 wherein the MAC unit is further configured to not select blocked TFCs as the selected TFC. 5. A method comprising: providing, by a user equipment, a plurality of logical channels, wherein each of the logical channels has an associated priority;selecting, by the user equipment, based on a maximum transmission power level, a transport format combination (TFC) associated with a medium access control (MAC) protocol data unit (PDU) that maximizes transmission of data of a logical channel having a highest priority such that no other TFC that maximizes the transmission of highest priority data has a lower bit rate than the selected TFC; andgenerating, and transmitting, a MAC PDU based on the selected TFC. 6. The method of claim 5 wherein the user equipment multiplexes data into the MAC PDU considering a MAC header. 7. The method of claim 5 wherein on a condition that a plurality of logical channels have the highest priority, a logical channel out of the plurality of logical channels is selected randomly. 8. The method of claim 5 wherein blocked TFCs are not selected as the selected TFC.
