Abstract
In wireless communication with another communication apparatus in a predetermined wireless network, overhead information defined in a media access control layer is divided into a header of information necessary for the common access control and a header of information necessary for each payload. Address information is added to the header of information necessary for the common access control to transmit the generated header attached to the transmission data. For example, in a case of forming a physical burst in which a plurality of data payloads are combined into one, a frame structure is provided without useless repetition of address information.
Claims19
A wireless communication apparatus for wireless communication with another communication apparatus, comprising:
- data generation unit to generate a data having a first media access control (MAC) header and second MAC headers,
- wherein the first MAC header includes a frame type information, a plurality of address information and a type of retransmission request information requested for confirmation of receiving the data as a common header to a plurality of data payloads,
- wherein the second MAC headers include payload length information respectively for the data payloads as a sub header to each of the data payloads,
- wherein the first MAC header is arranged subsequent to a physical (PHY) header transmitted at a predetermined fixed transmission rate, and
- wherein said data generation unit is to generate at least one of the second MAC headers and data payload thereof set for transmission at a variable transmission rate in accordance with a parameter of the PHY header used for a process in a physical layer;
- and
- wireless transmission unit to transmit the data generated by the data generation unit.
A method of effecting wireless communication, comprising the steps of:
- effecting a process of generating a data having a first media access control (MAC) header and second MAC headers,
- wherein the first MAC header includes a frame type information, a plurality of address information and a type of retransmission request information requested for confirmation of receiving the data as a common header to a plurality of data payloads,
- wherein the second MAC headers include payload length information respectively for the data payloads as a sub header to each of the data payloads, and
- wherein the first MAC header is arranged subsequent to a physical (PHY) header transmitted at a predetermined fixed transmission rate;
- effecting a process of generating at least one of the second MAC headers and data payload thereof set for transmission at a variable transmission rate in accordance with a parameter of the PHY header used for a process in a physical layer;
- and
- wirelessly transmitting the data generated.
A program on a non-transitory computer-readable medium executable by a computer for effecting a process of wireless communication, the program including information comprising the steps of:
- effecting, by the computer, a process of generating a data having a first media access control (MAC) header and second (MAC) headers,
- wherein the first MAC header includes a frame type information, a plurality of address information and a type of retransmission request information requested for confirmation of receiving the data as a common header to a plurality of data payloads,
- wherein the second MAC headers include payload length information respectively for the data payloads as a sub header to each of the data payloads, and
- wherein the first MAC header is arranged subsequent to a physical (PHY) header transmitted at a predetermined fixed transmission rate;
- effecting a process of generating at least one of the second MAC headers and data payload thereof set for transmission at a variable transmission rate in accordance with a parameter of the PHY header used for a process in a physical layer;
- and wirelessly transmitting the data generated.
