Assignee:

Sharp Kabushiki Kaisha - Osaka

International Classification:

H04W 4/00

US Classification:

370338, 370329

Abstract:

A method of selectively providing MIMO transmission/reception in a WLAN system includes using a TSPEC reservation and signaling mechanism to instantiate and tear down, dynamically, multi-channel operation in a WLAN; providing an inference algorithm to determine the minimum number of channels required to establish a TSPEC using a MIMO WLAN system; providing specific channel parameters as parameters to be negotiated in the TSPEC; providing frame exchange sequences to be used in Enhanced Distributed Coordinated Access contention based access and to be used in polled access; and providing a mechanism wherein an access point makes a decision as to whether to admit MIMO functionality on a given link, wherein a “link” is a set of communications between two specific WLAN stations.

US Classification:

370330, 370336, 370338

Abstract:

Methods and apparatus for extended reverse direction grant in a WLAN. In an aspect, a method includes transmitting data within a transmit interval to a plurality of the nodes, wherein the data comprises a first indicator. The method also includes receiving, in response to the first indicator, a data transmission from at least one of the nodes, wherein the data transmission was transmitted using a selected transmission resource and is received within the transmit interval. In an aspect, an apparatus includes a receiver to receive, within a time interval, first data over a common channel, the first data being decodable by other nodes. The apparatus also includes a controller to determine whether the first data comprises a first indicator, and a transmitter to transmit second data within the time interval using selected transmission resources, if the first data comprises the first indicator.

International Classification:

H04J 3/00

US Classification:

370345

Abstract:

Methods and apparatus for delayed block acknowledgments in a WLAN. In an aspect, a method is provided for communication with one or more nodes. The method includes transmitting to the one or more nodes a block comprising data and a first bit indicating no acknowledgements for the data are to be transmitted from the one or more nodes. The method also includes determining whether a selected time location within a transmit time duration has been reached, wherein if the selected time location has been reached, transmitting to the one or more nodes a second bit indicating that the one or more nodes are to transmit one or more acknowledgements, respectively, for the data. The method also includes receiving at least one acknowledgment for the data within a remaining portion of the transmit time duration.

Ashok RANGANATH - Los Gatos CA, US

International Classification:

H04W 74/08
H04L 5/00
H04W 56/00
H04W 84/12

Abstract:

Methods and a devices are provided is for receiving simultaneous downlink transmissions at a mobile station (STA). Information regarding whether endings of simultaneous data transmissions to the mobile station are to be aligned is transmitted to an access point (AP). The simultaneous data transmissions are between the AP and the STA over a pair of channels. Reception begins of a first data transmission, from the AP, on a first channel of the pair of channels. Reception begins of a second data transmission, from the AP, on a second channel of the pair of channels. The second data transmission overlaps at least a portion of the first data transmission. Reception of the second data transmission ends upon an end of the first data transmission when the information indicates that the endings of simultaneous downlink data transmissions are to be aligned.
