Abstract

Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. 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, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

First claim

1 - 22 . (canceled)

23 . A method of communication for an apparatus, comprising:
communicating first beam information via a first control channel of a first beamformed wireless communication link; and communicating second beam information via a second control channel of a second beamformed wireless communication link, wherein the first control channel is independent of the second control channel.

24 . The method of claim 23 , further comprising:
communicating first transport blocks via the first beamformed wireless communication link; and communicating second transport blocks via the second beamformed wireless communication link; and processing the first transport blocks independently of the second transport blocks.

25 . The method of claim 24 , wherein the processing comprises error processing.

26 . The method of claim 24 , wherein the processing comprises cyclic redundancy check (CRC) processing.

27 . The method of claim 24 , wherein:
the communication of the first transport blocks is via a first beam; and the communication of the second transport blocks is via a second beam.

28 . The method of claim 23 , wherein:
the communication via the first beamformed wireless communication link uses a first radio frequency (RF) chain of the apparatus; and the communication via the second beamformed wireless communication link uses a second RF chain of the apparatus.

29 . The method of claim 23 , wherein:
the communication via the first beamformed wireless communication link uses a first antenna sub-array of the apparatus; and the communication via the second beamformed wireless communication link uses a second antenna sub-array of the apparatus.

30 . An apparatus for communication, comprising:
a memory; and a processor coupled to the memory, wherein the memory stores instructions, which, when executed by the processor, cause the apparatus to:
communicate first beam information via a first control channel of a first beamformed wireless communication link; and
communicate second beam information via a second control channel of a second beamformed wireless communication link, wherein the first control channel is independent of the second control channel.

31 . The apparatus of claim 30 , wherein the instructions, when executed by the processor, further cause the apparatus to:
communicate first transport blocks via the first beamformed wireless communication link; communicate second transport blocks via the second beamformed wireless communication link; and process the first transport blocks independently of the second transport blocks.

32 - 33 . (canceled)

34 . A non-transitory computer-readable medium storing instructions which, when executed by a computer, cause the computer to:
communicate first beam information via a first control channel of a first beamformed wireless communication link; and communicate second beam information via a second control channel of a second beamformed wireless communication link, wherein the first control channel is independent of the second control channel.

35 . The apparatus of claim 31 , wherein the processing comprises error processing.

36 . The apparatus of claim 31 , wherein the processing comprises cyclic redundancy check (CRC) processing.

37 . The apparatus of claim 31 , wherein:
the communication of the first transport blocks is via a first beam; and the communication of the second transport blocks is via a second beam.

38 . The apparatus of claim 30 , wherein:
the communication via the first beamformed wireless communication link uses a first radio frequency (RF) chain of the apparatus; and the communication via the second beamformed wireless communication link uses a second RF chain of the apparatus.

39 . The apparatus of claim 30 , wherein:
the communication via the first beamformed wireless communication link uses a first antenna sub-array of the apparatus; and the communication via the second beamformed wireless communication link uses a second antenna sub-array of the apparatus.

40 . The non-transitory computer-readable medium of claim 34 , wherein the instructions, when executed by the computer, further cause the computer to:
communicate first transport blocks via the first beamformed wireless communication link; communicate second transport blocks via the second beamformed wireless communication link; and process the first transport blocks independently of the second transport blocks.

41 . The non-transitory computer-readable medium of claim 40 , wherein the processing comprises error processing.

42 . The non-transitory computer-readable medium of claim 40 , wherein the processing comprises cyclic redundancy check (CRC) processing.

43 . The non-transitory computer-readable medium of claim 40 , wherein:
the communication of the first transport blocks is via a first beam; and the communication of the second transport blocks is via a second beam.

44 . The non-transitory computer-readable medium of claim 34 , wherein:
the communication via the first beamformed wireless communication link uses a first radio frequency (RF) chain of the apparatus; and the communication via the second beamformed wireless communication link uses a second RF chain of the apparatus.
