Abstract
Aspects described herein relate to wireless communications. According to some aspects, a first base station may coordinate with a second base station to select beamforming codewords. The first base station may receive an index indicating beamforming codewords used by a second base station. The first base station may select a beamforming codeword for use in transmitting signals to a wireless device based on the beamforming codeword indicated by the second base station.
Claims33
A method comprising:
- receiving, by a first access point and from a second access point, an indication of a second beamforming codebook, associated with the second access point, comprising a plurality of beamforming matrixes;
- receiving, by the first access point and from the second access point, at least one first frame indicating at least one index associated with a subset of beamforming matrixes of the plurality of beamforming matrixes;
- and
- transmitting, by the first access point and to at least one device, at least one second frame using one or more first beamforming matrixes selected, by the first access point, based on the at least one index associated with the subset of beamforming matrixes of the plurality of beamforming matrixes.
A first access point comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the first access point to:
- receive, from a second access point, an indication of a second beamforming codebook, associated with the second access point, comprising a plurality of beamforming matrixes;
- receive, from the second access point, at least one first frame indicating at least one index associated with a subset of beamforming matrixes of the plurality of beamforming matrixes;
- and
- transmit, to at least one device, at least one second frame using one or more first beamforming matrixes selected, by the first access point, based on the at least one index associated with the subset of beamforming matrixes of the plurality of beamforming matrixes.
A non-transitory computer readable medium comprising instructions that, when executed, configure a first access point to:
- receive, from a second access point, an indication of a second beamforming codebook, associated with the second access point, comprising a plurality of beamforming matrixes;
- receive, from the second access point, at least one first frame indicating at least one index associated with a subset of beamforming matrixes of the plurality of beamforming matrixes;
- and
- transmit, to at least one device, at least one second frame using one or more first beamforming matrixes selected, by the first access point, based on the at least one index associated with the subset of beamforming matrixes of the plurality of beamforming matrixes.
A system comprising:
- a first access point;
- and
- a second access point,
- wherein the first access point is configured to:
- transmit, to at least one device, at least one second frame using one or more first beamforming matrixes selected, by the first access point, based on at least one index associated with a subset of beamforming matrixes of a plurality of beamforming matrixes;
- and
- wherein the second access point is configured to:
- transmit, to the first access point, at least one first frame indicating the at least one index associated with the subset of beamforming matrixes of the plurality of beamforming matrixes.
