Abstract

Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

First claim

What is claimed is:

1. A non-transitory computer-readable medium storing computer-executable code for a user equipment, including code to:
obtain first reference signal received power (RSRP) measurement information for a first beam of a first beamformed wireless communication link;
obtain second reference signal received power (RSRP) measurement information for a second beam of a second beamformed wireless communication link;
determine whether a threshold has been satisfied using the first RSRP measurement information for the first beam of the first beamformed wireless communication link, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link, which was obtained by the user equipment; and
generate an event trigger based on the determination of whether the threshold has been satisfied that used the first RSRP measurement information for the first beam of the first beamformed wireless communication link, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link, which was obtained by the user equipment.

2. A method of communication for a user equipment, comprising:
obtaining first reference signal received power (RSRP) measurement information for a first beam of a first beamformed wireless communication link with a first transmit receive point;
obtaining second reference signal received power (RSRP) measurement information for a second beam of a second beamformed wireless communication link with a second transmit receive point;
determining whether a threshold has been satisfied using the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment; and
generating an event trigger based on the determination of whether the threshold has been satisfied that used the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment.

3. The method of claim 2 , wherein the first beamformed wireless communication link with the first transmit receive point is carried on a first carrier frequency; and
wherein the second beamformed wireless communication link with the second transmit receive point is carried on the first carrier frequency on which the first beamformed wireless communication link with the first transmit receive point is also carried.

4. A user equipment for communication, comprising:
a memory; and
a processor coupled to the memory, wherein the processor and the memory are configured to:
obtain first reference signal received power (RSRP) measurement information for a first beam of a first beamformed wireless communication link with a first transmit receive point;
obtain second reference signal received power (RSRP) measurement information for a second beam of a second beamformed wireless communication link with a second transmit receive point;
determine whether a threshold has been satisfied using the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment; and
generate an event trigger based on the determination of whether the threshold has been satisfied that used the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment.

5. The user equipment of claim 4 , wherein the first beamformed wireless communication link with the first transmit receive point is carried on a first carrier frequency; and
wherein the second beamformed wireless communication link with the second transmit receive point is carried on the first carrier frequency on which the first beamformed wireless communication link with the first transmit receive point is also carried.

6. A user equipment for communication, comprising:
means for obtaining first reference signal received power (RSRP) measurement information for a first beam of a first beamformed wireless communication link with a first transmit receive point;
means for obtaining second reference signal received power (RSRP) measurement information for a second beam of a second beamformed wireless communication link with a second transmit receive point;
means for determining whether a threshold has been satisfied using the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment; and
means for generating an event trigger based on the determination of whether the threshold has been satisfied that used the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment.

7. The user equipment of claim 6 , wherein the first beamformed wireless communication link with the first transmit receive point is carried on a first carrier frequency; and
wherein the second beamformed wireless communication link with the second transmit receive point is carried on the first carrier frequency on which the first beamformed wireless communication link with the first transmit receive point is also carried.

8. A non-transitory computer-readable medium storing computer-executable code for a user equipment, including code to:
obtain first reference signal received power (RSRP) measurement information for a first beam of a first beamformed wireless communication link with a first transmit receive point;
obtain second reference signal received power (RSRP) measurement information for a second beam of a second beamformed wireless communication link with a second transmit receive point;
determine whether a threshold has been satisfied using the first RSRP measurement information for the first beam of the first beamformed wireless communication link with the first transmit receive point, which was obtained by the user equipment, and the second RSRP measurement information for the second beam of the second beamformed wireless communication link with the second transmit receive point, which was obtained by the user equipment; and
generate an event trigger based on the determination of whether the threshold has been satisfied th
