Apparatus, method and non-transitory, computer readable storage media for transmitting and receiving discontinuous time-frequency operation signals in a communication network

A receive apparatus for receiving discontinuous time-frequency operation, DTFO, signals in a communication network, the apparatus comprising

• a receiver configured to receive a DTFO signal comprising monitoring symbols and regular DTFO symbols in the communication network;
• and
• processing circuitry, which is coupled to the receiver and configured to
• obtain at least one monitoring symbol from the DTFO signal if a time gap of the DTFO signal between two subsequent regular DTFO symbols exceeds a first time threshold;
• obtain a training sequence from the DTFO signal if a time period between a last reception of a monitoring or regular DTFO symbol and a subsequent reception of a DTFO symbol exceeds a second time threshold, the training sequence comprising at least one monitoring symbol preceding a regular DTFO symbol;
• and
• use the at least one monitoring symbol for frequency-domain equalizer, FEQ, adjustment at the receiver.

A method for transmitting discontinuous time-frequency operation, DTFO, signals in a communication network, the method comprising:

• transmitting a DTFO signal comprising monitoring symbols and regular DTFO symbols in the communication network;
• generating at least one monitoring symbol for transmission if a time gap of the DTFO signal between two subsequent regular DTFO symbols exceeds a first time threshold, wherein the at least one monitoring symbol is configured to enable frequency-domain equalizer, FEQ, adjustment at a receiver of the DTFO signal;
• and
• generating a training sequence for transmission if a time period between a last transmission of a monitoring or regular DTFO symbol and a subsequent transmission of a DTFO symbol exceeds a second time threshold, the training sequence comprising at least one monitoring symbol preceding a regular DTFO symbol.

One or more non-transitory, computer readable storage media comprising a plurality of instructions stored thereon that in response to being executed result in a computing device performing a method for transmitting discontinuous time-frequency operation, DTFO, signals in a communication network, the method comprising:

• transmitting a DTFO signal comprising monitoring symbols and regular DTFO symbols in the communication network;
• generating at least one monitoring symbol for transmission if a time gap of the DTFO signal between two subsequent regular DTFO symbols exceeds a first time threshold, wherein the at least one monitoring symbol is configured to enable frequency-domain equalizer, FEQ, adjustment at a receiver of the DTFO signal;
• and
• generating a training sequence for transmission if a time period between a last transmission of a monitoring or regular DTFO symbol and a subsequent transmission of a DTFO symbol exceeds a second time threshold, the training sequence comprising at least one monitoring symbol preceding a regular DTFO symbol.
