Abstract
In some examples, a first wireless device includes a network interface capable of communicating using 16 spatial streams; and at least one processor configured to allocate at least one spatial stream of the 16 spatial streams to a plurality of wireless devices, such that no wireless device of the plurality of wireless devices is allocated more than 4 spatial streams, and send a control information element indicating the allocation of the at least one spatial stream to the plurality of wireless devices.
Claims27
A first wireless device comprising:
- a non-transitory storage medium to store a spatial configuration table including different entries representing different spatial configurations that correspond to different allocations of spatial streams to a plurality of wireless devices;
- a network interface capable of communicating using 16 spatial streams;
- and
- at least one processor configured to:
- allocate at least one spatial stream of the 16 spatial streams to the plurality of wireless devices, such that no wireless device of the plurality of wireless devices is allocated more than 4 spatial streams, and
- send a control information element indicating the allocation of the at least one spatial stream to the plurality of wireless devices, wherein the control information element comprises a value of a six-bit index that maps to a respective spatial configuration of the different spatial configurations of the spatial configuration table.
3 more elements
A method performed by a first wireless device, comprising:
- storing a spatial configuration table in a storage medium of the first wireless device, wherein the spatial configuration table includes different entries representing different spatial configurations that correspond to different allocations of spatial streams to a plurality of wireless devices;
- allocating at least one spatial stream of 16 available spatial streams to the plurality of wireless devices in a wireless network, such that no wireless device of the plurality of wireless devices is allocated more than 4 spatial streams;
- and
- sending a control information element indicating the allocation of the at least one spatial stream of the 16 available spatial streams to the plurality of wireless devices, wherein the control information element comprises a value of a six-bit index that maps to a respective spatial configuration of the different spatial configurations of the spatial configuration table.
1 more element
A first wireless device comprising:
- a network interface capable of communicating over a plurality of spatial streams;
- a non-transitory storage medium to store a spatial configuration data structure comprising a plurality of entries representing different allocations of spatial streams to a plurality of wireless devices, wherein none of the different allocations of spatial streams allocates more than 4 spatial streams to a wireless device;
- and
- at least one processor configured to receive, from a second wireless device, a control information element that maps to an entry of the plurality of entries, wherein the control information element comprises a six-bit index that maps to the entry of the spatial configuration data structure, the entry mapped by the control information element comprising an allocation of spatial streams to at least some of the plurality of wireless devices.
1 more element
A method performed by a first wireless device, comprising:
- storing, in a storage medium, a spatial configuration data structure comprising a plurality of entries representing different allocations of spatial streams to a plurality of wireless devices, wherein none of the different allocations of spatial streams allocates more than 4 spatial streams to a wireless device;
- and
- receiving, from a second wireless device, a control information element that maps to an entry of the plurality of entries, wherein the control information element comprises a six-bit index that maps to the entry of the spatial configuration data structure, the entry mapped by the control information element comprising an allocation of spatial streams to at least some of the plurality of wireless devices.
