Abstract

Provided are an information determination method and apparatus, a signal reception method and apparatus and a signal transmission method and apparatus. A wireless communication device may determine parameter information of a measurement reference signal according to a predetermined rule. The wireless communication device may receive the measurement reference signal according to the determined parameter information from a wireless communication node.

First claim

We claim:

1. A signal reception method, comprising:
receiving, by a wireless communication device from a wireless communication node, an aperiodic measurement reference signal according to quasi-co-location reference signals of one resource index of the aperiodic measurement reference signal,
wherein a plurality of aperiodic measurement reference signal resource sets comprises the one resource index of the aperiodic measurement reference signal, and the plurality of aperiodic measurement reference signal resource sets correspond to a same time offset,
wherein the quasi-co-location reference signals of the one resource index of the aperiodic measurement reference signal have a same configuration and are same in the plurality of aperiodic measurement reference signal resource sets, and
wherein the quasi-co-location reference signals satisfy a quasi-co-location relationship with the aperiodic measurement reference signal associated with the one resource index.

2. The method of claim 1 , wherein the plurality of aperiodic measurement reference signal resource sets have the one resource index and belong to a same component carrier at a same time moment.

3. The method of claim 1 , wherein the plurality of aperiodic measurement reference signal resource sets correspond to one trigger state.

4. The method of claim 3 , wherein the one trigger state is associated with a plurality of configuration information.

5. The method of claim 1 , wherein the one resource index of the aperiodic measurement reference signal is indicative of a highest resource index in a frequency domain bandwidth.

6. A wireless communication device, comprising: at least one processor configured to:
receive, via a receiver from a wireless communication node, an aperiodic measurement reference signal according to quasi-co-location reference signals of one resource index of the aperiodic measurement reference signal,
wherein a plurality of aperiodic measurement reference signal resource sets comprises the one resource index of the aperiodic measurement reference signal, and the plurality of aperiodic measurement reference signal resource sets correspond to a same time offset,
wherein the quasi-co-location reference signals of the one resource index of the aperiodic measurement reference signal have a same configuration and are same in the plurality of aperiodic measurement reference signal resource sets, and
the quasi-co-location reference signals satisfy a quasi-co-location relationship with the aperiodic measurement reference signal associated with the one resource index.

7. The wireless communication device of claim 6 , wherein the plurality of aperiodic measurement reference signal resource sets have the one resource index and belong to a same component carrier at a same time moment.

8. The wireless communication device of claim 6 , wherein the plurality of aperiodic measurement reference signal resource sets correspond to one trigger state.

9. The wireless communication device of claim 8 , wherein the one trigger state is associated with a plurality of configuration information.

10. The wireless communication device of claim 6 , wherein the one resource index of the aperiodic measurement reference signal is indicative of a highest resource index in a frequency domain bandwidth.

11. A method comprising:
determining, by a wireless communication node, quasi-co-location reference signals of one resource index of an aperiodic measurement reference signal in a plurality of aperiodic measurement reference signal resource sets have a same configuration and are the same in response to each of the plurality of aperiodic measurement reference signal resource sets comprises the one resource index of an aperiodic measurement reference signal, the plurality of aperiodic measurement reference signal resource sets correspond to a same time offset, and the quasi-co-location reference signals satisfy a quasi-co-location relationship with the aperiodic measurement reference signal associated with the one resource index; and
sending, by the wireless communication node, the aperiodic measurement reference signal according to the determined quasi-co-location reference signals.

12. The method of claim 11 , wherein the plurality of aperiodic measurement reference signal resource sets have the one resource index and belong to a same component carrier at a same time moment.

13. The method of claim 11 , wherein the plurality of aperiodic measurement reference signal resource sets correspond to one trigger state.

14. The method of claim 13 , wherein the one trigger state is associated with a plurality of configuration information.

15. The method of claim 11 , wherein the one resource index of the aperiodic measurement reference signal is indicative of a highest resource index in a frequency domain bandwidth.

16. A wireless communication node, comprising:
at least one processor configured to:
determine quasi-co-location reference signals of a resource index of an aperiodic measurement reference signal in one plurality of aperiodic measurement reference signal resource sets have a same configuration and are the same in response to each of the plurality of aperiodic measurement reference signal resource sets comprises the one resource index of an aperiodic measurement reference signal, the plurality of aperiodic measurement reference signal resource sets correspond to a same time offset, and the quasi-co-location reference signals satisfy a quasi-co-location relationship with the aperiodic measurement reference signal associated with the one resource index; and
send, via a transmitter to a wireless communication device, the aperiodic measurement reference signal according to the determined quasi-co-location reference signals.

17. The wireless communication node of claim 16 , wherein the plurality of aperiodic measurement reference signal resource sets have the one resource index and belong to a same component carrier at a same time moment.
