Abstract
Certain aspects of the present disclosure provide methods and apparatus for enhancing a sector sweep. The apparatus generally includes a processing system configured to generate a first set of frames and a second set of frames. The apparatus also includes a first interface configured to output the first set of frames for transmission to a wireless node via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and output the second set of frames for transmission to the wireless node via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension.

An apparatus for wireless communication, comprising:
- a processing system configured to generate a first set of frames and a second set of frames;
- and
- a first interface configured to:
- output the first set of frames for transmission to a wireless node via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and wherein each beam of the first set corresponds to a different transmit direction along the first dimension that is associated with a different angle in the second dimension, and
- output the second set of frames for transmission to the wireless node via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension, and wherein each beam of the second set corresponds to a different transmit direction along the second dimension that is associated with a different angle in the first dimension.
An apparatus for wireless communication, comprising:
- a first interface configured to obtain, from a wireless node,
- a first set of frames transmitted via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and
- a second set of frames transmitted via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension;
- and
- a processing system configured to:
- determine reception parameters for the first and second sets of frames, and
- determine at least one of an angle of departure of the first and second sets of frames, a location of the apparatus relative to the wireless node, or an absolute location of the apparatus based on the reception parameters.
A method for wireless communication by an apparatus, comprising:
- generating a first set of frames and a second set of frames;
- outputting the first set of frames for transmission to a wireless node via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and wherein each beam of the first set corresponds to a different transmit direction along the first dimension that is associated with a different angle in the second dimension;
- and
- outputting the second set of frames for transmission to the wireless node via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension, and wherein each beam of the second set corresponds to a different transmit direction along the second dimension that is associated with a different angle in the first dimension.
A method for wireless communication by an apparatus, comprising:
- obtaining, from a wireless node,
- a first set of frames transmitted via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and
- a second set of frames transmitted via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension;
- determining reception parameters for the first and second sets of frames;
- and
- determining at least one of an angle of departure of the first and second sets of frames, a location of the apparatus relative to the wireless node, or an absolute location of the apparatus based on the reception parameters.
