Abstract
A data signal is transmitted in a wireless communication system from a primary station to a secondary station. The data signal comprising a medium access control header (MAC-hs header) and a protocol data unit associated with the medium access control header. The medium access control header comprising a set at least one field (e.g. TSN, SEG, LI, FMT, LCid), wherein a size allocated to at least one field of the set is determined based on a length of the protocol data unit.
Claims10
A wireless telecommunication device comprising:
- a processing circuit configured to encapsulate a radio link control (RLC) protocol data unit (PDU) with a media access control (MAC) header to generate a media access control (MAC) protocol data unit (PDU), the MAC header comprising a plurality of fields including a format field which indicates a size of one or more of the plurality of fields, the processing circuit being configured to determine a size of the radio link control (RLC) protocol data unit (PDU) and configure a size of a length indicator field of the header based on the determined size, wherein the size of the length indicator field is variable based on the protocol data unit;
- and
- a transmitter configured to transmit the media access control (MAC) protocol data unit (PDU) in a data signal.
A wireless telecommunication device, comprising:
- a receiver configured to receive a data signal including a media access control (MAC) protocol data unit (PDU), the media access control (MAC) protocol data unit (PDU) comprising a header, the header comprising a plurality of fields including a format field which indicates a size of at least one of the plurality of fields, and wherein the plurality of fields further includes a length indicator indicating a size of a length of the protocol data unit (PDU), wherein the size of the length indicator field is variable based on the protocol data unit;
- and
- a processing circuit configured to de-encapsulate the media access protocol (MAC) protocol data unit (PDUC) from the data signal based on the media access control (MAC) header to derive a radio link control (RLC) protocol data unit (PDU).
