Abstract

There is disclosed a method of operating a radio node in a wireless communication network, the method including communicating based on a signaling structure, the signaling structure including a number R of long symbols and/or a number Nsym of regular symbols, wherein R and/or Nsym is based on the subcarrier spacing associated to the signaling structure and/or a cyclic prefix length of a long symbol and/or a cyclic prefix length of a regular symbol. The disclosure also pertains to related devices and methods.

Claims (47)

1. A method of operating a radio node in a wireless communication network, the method comprising:

communicating based on a signaling structure, the signaling structure comprising at least one of a number R of long symbols and a number Nsym of regular symbols, a long symbol having a long cyclic prefix (CP) that does not exceed a length of a symbol part of a long symbol for a given subcarrier spacing.

2. The method according to claim 1 , wherein the signaling structure corresponds to one of:

one symbol and an associated cyclic prefix; and

a half-subframe.

3. The method according to claim 2 , wherein the signaling structure includes one long symbol, wherein the symbol length of the symbol part of the long symbol is at least as long as the cyclic prefix length.

4. The method according to claim 2 , wherein the cyclic prefix length is at least one of represented by and corresponds to one of a number of samples and a duration in time.

5. The method according to claim 1 , wherein the cyclic prefix length is at least one of represented by and corresponds to one of a number of samples and a duration in time.

6. The method according to claim 1 , wherein communicating is based on an OFDM-based waveform.

7. The method according to claim 1 , wherein a subcarrier spacing associated to the signaling structure corresponds to at least 960 KHz.

8. A radio node for a wireless communication network, the radio node comprising radio circuitry configured to communicate based on a signaling structure, the signaling structure comprising at least one of a number R of long symbols and a number Nsym of regular symbols, a long symbol having a long cyclic prefix (CP) that does not exceed a length of a symbol part of a long symbol for a given subcarrier spacing.

9. A method of operating a radio node in a wireless communication network, the method comprising:

communicating based on a signaling structure, the signaling structure comprising one or more symbols, a cyclic prefix with a cyclic prefix length being associated to each of the one or more symbols, the cyclic prefix length being at least one of based on, representable by and corresponding to
