Abstract
A communication apparatus transmits or receives an Extremely High Throughput (EHT) single-user (SU) physical-layer protocol data unit (PPDU), an EHT extended range (ER) SU PPDU, or an EHT multi-user (MU) PPDU. The transmitted or received EHT PPDU includes an EHT signal field (EHT-SIG) which includes a field indicating information regarding semi-orthogonal multiple access (SOMA).
Claims9
A communication apparatus comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the communication apparatus is caused, by the at least one processing circuit executing the instructions and/or the at least one processing circuit itself operating, to perform operations comprising:
- determining as to whether a plurality of communication apparatuses support semi-orthogonal multiple access (SOMA) technique or not;
- judging, based on the determination, whether to use the SOMA technique for communicating the radio frame;
- and
- transmitting a radio frame,
- wherein the radio frame includes a field common to the plurality of communication apparatuses and the field contains first information on whether the SOMA technique is used to communicate the radio frame and the radio frame includes second information indicating whether it is required to perform a Successive Interference Cancellation (SIC) process.
A method of a communication apparatus, the method comprising:
- determining as to whether a plurality of communication apparatuses support semi-orthogonal multiple access (SOMA) technique or not;
- judging, based on the determination, whether to use the SOMA technique for communicating the radio frame;
- and
- transmitting or receiving a radio frame,
- wherein the radio frame includes a field common to the plurality of communication apparatuses and the field contains first information on whether the SOMA technique is used to communicate the radio frame and the radio frame includes second information indicating whether it is required to perform a Successive Interference Cancellation (SIC) process.
A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of a communication apparatus, the control method comprising:
- determining as to whether a plurality of communication apparatuses support semi-orthogonal multiple access (SOMA) technique or not;
- judging, based on the determination, whether to use the SOMA technique for communicating the radio frame;
- and
- transmitting or receiving a radio frame,
- wherein the radio frame includes a field common to the plurality of communication apparatuses and the field contains first information on whether the SOMA technique is used to communicate the radio frame and the radio frame includes second information indicating whether it is required to perform a Successive Interference Cancellation (SIC) process.
