Multiple Access Point Channel Planning

US Patent:
20190281608, Sep 12, 2019
Filed:
Mar 9, 2018
Appl. No.:
15/917488
Inventors:
- San Diego CA, US
Ahmed Ragab Elsherif - San Jose CA, US
Srinivas Katar - Fremont CA, US
Ajay Kumar Pathak - Fremont CA, US
Manish Shukla - Milpitas CA, US
Bharat Bhushan - Fremont CA, US
Ramaswamy Venkateshwaran - Dublin CA, US
International Classification:
H04W 72/10
H04W 48/20
H04L 12/733
Abstract:
This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.

Throughput Optimization By Guard Interval Selection From Beamforming Feedback

US Patent:
20190007114, Jan 3, 2019
Filed:
Jun 30, 2017
Appl. No.:
15/640184
Inventors:
- San Diego CA, US
Xiaoxin Zhang - Sunnyvale CA, US
Ahmed Ragab Elsherif - San Jose CA, US
International Classification:
H04B 7/06
H04B 7/0417
H04B 7/04
H04B 1/59
H04L 27/26
Abstract:
This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a method of wireless communication includes utilizing a sounding procedure to obtain compressed beamforming (CBF) information. The sounding procedure may be a single-user or multi-user sounding procedure. The CBF information may contain various information regarding a particular channel that an access point may use for transmission. The information may include per-tone SNR information which may be processed to determine characteristics of the channel. Various techniques may be utilized to determine the further characteristics of the channel. The determined characteristics of the channel may then be used to determine an appropriate guard interval (GI) between symbols that are to be transmitted. Appropriate GI selection in wireless communications may facilitate higher throughput while decreasing overhead due to unnecessary idle time.

Techniques For Grouping In Mu-Mimo Systems Based On Limited Probing

US Patent:
20180337709, Nov 22, 2018
Filed:
May 19, 2017
Appl. No.:
15/599971
Inventors:
- San Diego CA, US
Ahmed Ragab ELSHERIF - San Jose CA, US
Hao ZHU - Milpitas CA, US
Srinivas KATAR - Fremont CA, US
International Classification:
H04B 7/024
H04B 7/0452
H04L 1/00
H04W 88/06
H04W 24/08
H04L 25/08
Abstract:
The present disclosure provides techniques for grouping in multi-user multiple-input-multiple-output (MU-MIMO) systems by using limited probing. With more wireless stations (STAs) being used in MU-MIMO groups, the probing used to obtain packet error metrics to determine the throughput for selecting the MU-MIMO groups for transmission can become more complex and involve a larger overhead. To reduce the probing overhead, various techniques are described in this disclosure. For example, an access point (AP) can identify a trigger to initiate a packet error probing. In response to the trigger, the AP embeds one or more probing packets that are part of the packet error probing within a short interframe space (SIFS)-burst data transmission process to take advantage of the existing structure of the process. Then, the AP can update at least one packet error metric (e.g., packet error rate or PER) based on feedback received in response to the probing packets.

Access Point Managed Channel Correlation For Mu-Mimo

US Patent:
20180324801, Nov 8, 2018
Filed:
May 2, 2017
Appl. No.:
15/585099
Inventors:
- San Diego CA, US
Madhan Jaganathan - Cupertino CA, US
Ahmed Ragab Elsherif - San Jose CA, US
International Classification:
H04W 72/04
H04B 7/0452
H04B 17/309
H04B 1/38
Abstract:
Apparatuses and methods for reducing channel correlation between wireless nodes are disclosed. An apparatus may receive channel state information (CSI) from each of a plurality of wireless nodes and determine, for each of the plurality of wireless nodes, a level of channel correlation with other wireless nodes based, at least in part, on the received CSI. The apparatus may identify one or more of the plurality of wireless nodes for which the determined level of channel correlation is greater than or equal to a value, and then generate, for at least one of the identified wireless nodes, an instruction requesting at least one of the identified wireless nodes to adjust a parameter by an amount based on the determined level of channel correlation. The apparatus may provide the instruction for transmission to the at least one of the identified wireless nodes.

Inventors:
- San Diego CA, US
Madhan Jaganathan - Cupertino CA, US
Nathaniel David Houghton - San Jose CA, US
Madhavan Nair - Sunnyvale CA, US
Srinivas Katar - Fremont CA, US
Ahmed Ragab Elsherif - San Jose CA, US
International Classification:
H04W 72/12
H04W 72/04
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus may be configured to determine a scheduling metric for each respective station of a plurality of stations. The scheduling metric for each station may be based on an effective spatial-time-frequency physical layer (PHY) capability for the station and a consumption rate of spatial-time-frequency resources by the respective station. The effective spatial-time-frequency PHY capability for the station may be a product of a target percentage of spatial-time resources allocated to the station, an effective number of spatial streams supported by the respective station, and a maximum bandwidth. The consumption rate of spatial-time-frequency resources may be a transmit opportunity (TXOP) moving average of consumption rate by the station. The apparatus may be configured to schedule each station of the plurality of stations for communication based on the determined scheduling metric for each respective station.
