Transmission protection scheme

An apparatus comprising:

• at least one processor;
• and
• at least one memory comprising a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
• process a physical layer convergence protocol header of a transmission received in a wireless communication apparatus on a frequency band;
• determine from header information comprised in the received physical layer convergence protocol header whether or not at least one subsequent transmission associated with the transmission is expected on the frequency band after the transmission;
• and
• in response to determining on the basis of the header information that there will be at least one subsequent transmission after the transmission on the frequency band, suspend channel access of the wireless communication apparatus on the frequency band for a determined time period after the transmission, the determined time period comprising a transmission time interval of the at least one subsequent transmission.

A computer program product embodied on a non-transitory distribution medium readable by a computer and comprising program instructions which, when loaded into an apparatus, execute a computer process comprising:

• processing a physical layer convergence protocol header of a transmission received in a wireless communication apparatus on a frequency band;
• determining from header information comprised in the physical layer convergence protocol header whether or not at least one subsequent transmission associated with the transmission is expected on the frequency band after the transmission;
• and
• in response to determining on the basis of the header information that there will be at least one subsequent transmission after the transmission on the frequency band, suspending channel access of the wireless communication apparatus on the frequency band for a determined time period after the transmission, the determined time period comprising a transmission time interval of the at least one subsequent transmission.
