Abstract

There is disclosed a method of operating a transmitting radio node in a wireless communication network, the method including transmitting reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set. The disclosure also pertains to related devices and methods.

Claims (23)

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

transmitting reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set, the reference pilot sequences of the set being associated to control signalings of different aggregation levels.

2 . The method according to claim 1 , wherein each reference pilot sequence of the set is associated to control signaling.

3 . The method of claim 2 , wherein each reference pilot sequence of the set is associated to control signaling of a set of control signalings.

4 . The method according to claim 1 , wherein a subsequence of a sequence is determined by truncation or decimation.

5 . The method according to claim 1 , wherein a subsequence and an associated reference pilot sequence are associated to the same time/frequency location.

6 . The method according to claim 1 , wherein the reference pilot sequences of the set are based on one or more Zadoff-Chu sequences.

7 . The method according to claim 1 , wherein the set of reference pilot sequences consists of one reference pilot sequence and subsequences thereof.

8 . A transmitting radio node for a wireless communication network, the transmitting radio node comprising processing circuitry being configured to:

transmit reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set, the reference pilot sequences of the set being associated to control signalings of different aggregation levels.

9 . The transmitting radio node according to claim 8 , wherein each reference pilot sequence of the set is associated to control signaling.

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

receiving reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set, the reference pilot sequences of the set being associated to control signalings of different aggregation levels.

11 . The method according to claim 10 , wherein each reference pilot sequence of the set is associated to control signaling.

12 . The method of claim 10 , wherein each reference pilot sequence of the set is associated to control signaling of a set of control signalings.

13 . The method according to claim 10 , wherein a subsequence of a sequence is determined by truncation or decimation.

14 . The method according to claim 10 , wherein a subsequence and an associated reference pilot sequence are associated to the same time/frequency location.

15 . The method according to claim 10 , wherein the reference pilot sequences of the set are based on one or more Zadoff-Chu sequences.

16 . The method according to claim 10 , wherein the set of reference pilot sequences consists of one reference pilot sequence and subsequences thereof.

17 . A receiving radio node for a wireless communication network, the receiving radio node comprising processing circuitry being configured to:

receive reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set, the reference pilot sequences of the set being associated to control signalings of different aggregation levels.

18 . A non-transitory computer storage medium storing executable program instructions that, when executed, cause processing circuitry to at least one of control and perform a method, the method comprising:

transmitting reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set, the reference pilot sequences of the set being associated to control signalings of different aggregation levels.
