Abstract
Certain aspects of the present disclosure support techniques for simultaneous beam training of multiple pairs of wireless nodes for reduction of training overhead. Each pair of wireless nodes can utilize a different training sequence in order to mitigate interference. In one aspect, different training sequences can be based on different Golay codes with appropriate correlation properties.
Claims44
A method for wireless communications, comprising:
- selecting, by a first apparatus, a training sequence from a plurality of training sequences to perform beam training with a second apparatus simultaneously with beam training of at least one other pair of apparatuses;
- and
- performing the beam training with the second apparatus using the selected training sequence simultaneously with the beam training of the other pair of apparatuses.
An apparatus for wireless communications, comprising:
- a first circuit configured to select a training sequence from a plurality of training sequences to perform beam training with another apparatus simultaneously with beam training of at least one other pair of apparatuses;
- and
- a second circuit configured to perform the beam training with the other apparatus using the selected training sequence simultaneously with the beam training of the other pair of apparatuses.
An apparatus for wireless communications, comprising:
- means for selecting a training sequence from a plurality of training sequences to perform beam training with another apparatus simultaneously with beam training of at least one other pair of apparatuses;
- and
- means for performing the beam training with the other apparatus using the selected training sequence simultaneously with the beam training of the other pair of apparatuses.
The apparatus of claim 39, wherein a magnitude of normalized cyclic cross-correlation between any pair of training sequences from the plurality of training sequences is not greater than a tolerance value.
A computer-program product for wireless communications, comprising a computer-readable medium comprising instructions executable to:
- select, by a first apparatus, a training sequence from a plurality of training sequences to perform beam training with a second apparatus simultaneously with beam training of at least one other pair of apparatuses;
- and
- perform the beam training with the second apparatus using the selected training sequence simultaneously with the beam training of the other pair of apparatuses.
A wireless node, comprising:
- at least one antenna;
- a first circuit configured to select a training sequence from a plurality of training sequences to perform beam training with another wireless node simultaneously with beam training of at least one other pair of wireless nodes;
- a second circuit configured to perform the beam training with the other wireless node using the selected training sequence simultaneously with the beam training of the other pair of wireless nodes;
- and
- a transmitter configured to transmit via the at least one antenna a plurality of signals constructed based on the selected training sequence.
