Abstract
Methods, systems, and devices are described for wireless communication. In one aspect, a method of wireless communication includes selecting, by a wireless device, a first subset from a first set of candidate multi-user groups of stations. The first subset is based at least in part on first-level grouping metrics associated with the first set of candidate multi-user groups. The method further includes determining second-level grouping metrics associated with a second set of candidate multi-user groups. The second set corresponds to candidate multi-user groups having a greater number of stations or channel vectors than the first set, and the second set is based at least in part on the first subset.
Claims30
A method for wireless communication, comprising:
- selecting, by a wireless device, a first subset from a first set of candidate multi-user groups of stations, the first subset being based at least in part on first-level grouping metrics associated with the first set of candidate multi-user groups;
- and
- determining, by the wireless device, second-level grouping metrics associated with a second set of candidate multi-user groups, the second set corresponding to candidate multi-user groups having a greater number of stations or channel vectors than the first set, and the second set being based at least in part on the first subset.
A communications device, comprising:
- a candidate multi-user group subset selector to select a first subset from a first set of candidate multi-user groups of stations, the first subset being based at least in part on first-level grouping metrics associated with the first set of candidate multi-user groups;
- and
- a grouping metric determiner to determine second-level grouping metrics associated with a second set of candidate multi-user groups, the second set corresponding to candidate multi-user groups having a greater number of stations or channel vectors than the first set, and the second set being based at least in part on the first subset.
A communications device, comprising:
- means for selecting a first subset from a first set of candidate multi-user groups of stations, the first subset being based at least in part on first-level grouping metrics associated with the first set of candidate multi-user groups;
- and
- means for determining second-level grouping metrics associated with a second set of candidate multi-user groups, the second set corresponding to candidate multi-user groups having a greater number of stations or channel vectors than the first set, and the second set being based at least in part on the first subset.
A non-transitory computer-readable medium comprising computer-readable code that, when executed, causes a device to:
- select a first subset from a first set of candidate multi-user groups of stations, the first subset being based at least in part on first-level grouping metrics associated with the first set of candidate multi-user groups;
- and
- determine second-level grouping metrics associated with a second set of candidate multi-user groups, the second set corresponding to candidate multi-user groups having a greater number of stations or channel vectors than the first set, and the second set being based at least in part on the first subset.
