摘要:
A wireless access point (WAP) including: antennas, shared and discrete components forming transmit and receive chains coupled to the antenna for orthogonal frequency division multiplexed (OFDM) multiple-input multiple-output (MIMO) WLAN communications with wireless stations. The station set identifier identifies any legacy stations that do not support multi-user (MU) MIMO concurrent downlinks from the WAP, and a number of WLAN subnets for concurrent downlinks communications thereto. The subnet controller generates the WLAN subnets each having a discrete beacon channel together with a discrete medium access control (MAC) for collision sense multiple access (CSMA) uplinks from associated stations to the WAP, and concurrent downlinks from the WAP including concurrent downlinks to legacy stations associated with different subnets; and the subnet controller configured to inject virtual access control indicia into each of the subnets to control uplinks from legacy stations on each of the subnets to the WAP.

A wireless transceiver including: at least one antenna; a plurality of transmit and receive path components; an array of microphones; an acoustic spatial diagnostic circuit and a rule execution circuit. The plurality of components form transmit and receive paths coupled to the at least one antenna. The acoustic spatial diagnostic circuit couples to the array of microphones to successively sample an acoustic environment surrounding the wireless transceiver and to determine from each set of acoustic samples an acoustic spatial map of at least humans within the surrounding environment. The rule execution circuit couples to the spatial diagnostic circuit to execute an action proscribed by a selected rule when a related portion of the acoustic spatial map sampled by the spatial diagnostic circuit exhibits a correlation above a threshold amount with a spatial context condition associated with the selected rule.
摘要:
A wireless apparatus node supporting wireless communications on a wireless local area network (WLAN). The wireless apparatus node includes: a local link prober, a remote link prober, a cross-link interference estimator, and a concurrent access controller. The local link prober probes a target node for channel information characterizing a communication channel for a local link therewith. The remote link prober probes a pair of device nodes on the WLAN capable of forming a remote link for cross-channel information characterizing communication channels there between. The cross-link interference estimator estimates interference signal levels at each node of the remote link resulting from communication over the local link. The concurrent access controller is responsive to a determination of an active communication on the remote link to allow a concurrent communication on the local link when interference levels at the remote link fall below a threshold level.

A diagnostic system for spatial diagnosis of the WLAN includes: a sounding aggregator and a spatial correlator. The sounding aggregator is configured to aggregate multiple-input multiple-output (MIMO) channel state information (CSI) from channel soundings of the WLAN, including channel soundings between a wireless access point (WAP) node and associated station nodes on a selected one of a plurality of communication channels of the WLAN. The spatial correlator is coupled to the sounding aggregator and configured to correlate CSI from the channel soundings with spatial characteristics of the WLAN including at least one of: a change in location of a WLAN node, human activity among the WLAN nodes, and structural impediments among WLAN nodes.

The sounding feedback module is responsive to an explicit sounding from a transmitting one of the nodes to send feedback of multiple-input multiple-output (MIMO) channel state information (CSI) derived from the channel sounding to the transmitting one of the nodes for improving subsequent transmissions. The sounding feedforward module is configured to monitor changes in CSI since the last explicit sounding based on CSI determined from the subsequent transmissions of the transmitting one of the nodes and responsive to a determination of a change in CSI above a threshold amount, to feedforward to the transmitting one of the nodes indicia of the change in CSI.

The station set identifier is configured to identify at least one set of at least two station nodes among the plurality of station nodes and complementary communication options for each station in the at least one set which facilitate concurrent communications between the WAP and the stations in the set. The subnet controller is configured both to generate subnets equal in number to a number of stations in at least one set, and for each subnet an associated beacon channel discrete from the beacon channels of other subnets, together with any required aggregate channels matching each station's identified communication option and an associated medium access control, and further to control transmission of data from the WAP to the at least two station nodes concurrently on the associated subnets.

A wireless access point (WAP) including: antennas, shared and discrete components forming transmit and receive chains coupled to the antenna for orthogonal frequency division multiplexed (OFDM) multiple-input multiple-output (MIMO) WLAN communications with wireless stations. The station set identifier identifies any legacy stations that do not support multi-user (MU) MIMO concurrent downlinks from the WAP, and a number of WLAN subnets for concurrent downlinks communications thereto. The subnet controller generates the WLAN subnets each having a discrete beacon channel together with a discrete medium access control (MAC) for collision sense multiple access (CSMA) uplinks from associated stations to the WAP, and concurrent downlinks from the WAP including concurrent downlinks to legacy stations associated with different subnets; thereby enabling concurrent downlink communications with said legacy stations despite their lack of support for MU-MIMO.
