Abstract
A method, node device, signal, and instruction set to reduce the size of data packets in a telecommunications network. The invention provides a solution wherein a size of SDU position identifiers in a header of a packet data unit is optimized depending on the actual size of the packet data unit, reducing the amount of data sent in the telecommunication network.
Claims15
A receiving node in a wireless communication network,
- comprising a processor configured to:
- receive control signal information from a transmitting node arrangement with information about a size of a packet data unit (PDU);
- derive from the information about the size of the PDU a size of a Service Data Unit (SDU) position identifier, wherein the SDU position identifier indicates a position of an SDU in the PDU;
- receive the PDU from the transmitting node arrangement;
- and
- decode the received PDU based on the derived size of the SDU position identifier,
- wherein the processor is configured to receive the control signal information by receiving transport format information transmitted on a common control channel, wherein the common control channel is an L1 control channel.
A method for receiving data in a wireless communication network, comprising:
- receiving control signal information from a transmitting node arrangement with information about a size of a packet data unit (PDU);
- deriving from the information about the size of the PDU field a size of a Service Data Unit (SDU) position identifier, wherein the SDU position identifier indicates a position of an SDU in the PDU;
- receiving the PDU from the transmitting node arrangement;
- and
- decoding the received PDU based on the derived size of the SDU position identifier,
- wherein receiving the control signal information comprises receiving transport format information transmitted on a common control channel, wherein the common control channel is an L1 control channel.
An apparatus for receiving data In a wireless communication network, the apparatus comprising:
- a communication interface configured to communicate with a wireless communication network;
- and
- a processor configured to:
- receive control signal information from a transmitting node arrangement with information about a size of a packet data unit (PDU);
- derive from the information about the size of the PDU field a size of a Service Data Unit (SDU) position identifier, wherein the SDU position identifier indicates a position of an SDU in the PDU;
- receive the PDU from the transmitting node arrangement;
- and
- decode the received PDU based on the derived size of the SDU position identifier,
- wherein the processor is configured to receive the control signal information by receiving transport format information transmitted on a common control channel, wherein the common control channel is an L1 control channel.
