In some aspects, an access point may comprise a receiver configured to receive an access request message from a wireless station, the message comprising an indication of a plurality of network connection available to the wireless station including a link to a second access point. The receiver may be further configured to receive connectivity information associated with the link, based on the indication, from the second access point. The access point may further comprise a processor configured to determine whether to grant access to the wireless station based, at least in part, on the indication and the connectivity information, and a transmitter configured to transmit a response to the wireless station based on the determining.
Abstract:
A method and apparatus for setting Reverse Link CQI Reporting Modes in an access terminal is provided, comprising determining a value for CQIReportingMode received as a parameter in a transmitted message and setting the reverse link CQI reporting mode of the access terminal based on CQIReportingMode value. The CQIReportingMode value is indicative of a reporting mode selected from a plurality of reporting modes.
Abstract:
In a particular embodiment, a method includes scanning, by a mobile device, for a first wireless communication channel that is reserved for device authentication and association. The mobile device sends an authentication request to an access point via the first wireless communication channel. The method further includes receiving a reply to the authentication request from the access point.
Abstract:
In a particular embodiment, a method includes determining, by a first device, a number of discovery messages received during at least one discovery interval. Based on the number of discovery messages, an estimated number of devices in an ad-hoc network is determined The method further includes transmitting, during a second discovery interval that is subsequent to the at least one discovery interval, a discovery message. The discovery message indicates the estimated number of devices in the ad-hoc network.
Abstract:
Certain embodiments provide methods and apparatus for adjusting timing in an SDMA system. One method for adjusting the timing of packet transmissions in a wireless communications system, that may be performed by an access point, includes receiving ranging signals from a plurality of wireless network nodes, determining timing adjustment information for adjusting starting timing of packet transmissions from the wireless network nodes based on the ranging signals, and communicating the timing adjustment information to the wireless network nodes.
Abstract:
Systems, methods, and devices for narrowband channel selection in a wireless communications network are described herein. In one aspect, a wireless communications device includes a receiver, processor, and transmitter. The receiver is configured to wirelessly receive messages from a first device over a plurality of channels. The processor is configured to estimate a quality of each channel based on one message received from the first device over each channel, select for wireless communication a first channel of the plurality of channels based on the estimated quality of each channel, and prepare a selection message indicating selection of the first channel for wireless communication. The transmitter is configured to transmit the selection message to the first device.
Abstract:
Methods and devices for communicating in a communication system are described herein. One aspect provides a method of communicating over one or more space-time streams. The method includes transmitting a first stream with a bandwidth of 2 MHz or less. The method further includes transmitting, when there are at least two streams, a second stream with a cyclic shift delay relative to the first stream equal to half a period. The method further includes transmitting, when there are at least three streams, a third stream with a cyclic shift delay relative to one of the first and second stream equal to a quarter of the period. The method further includes transmitting, when there are at least four streams, a fourth stream with a cyclic shift delay relative to the other of the first and second stream equal to a quarter of the period.
Abstract:
Certain aspects of the present disclosure provide methods and apparatus for the coexistence of 1 MHz and 2 MHz operation modes within a wireless communication system in accordance with IEEE 802.11ah, for example. One example method generally includes scanning a plurality of channel pairs, wherein each of the channel pairs comprises a first channel having a first channel designation and a second channel having a second channel designation; determining, based on the scan, a set of open channels from the plurality of channel pairs in which no other apparatus is operating; selecting a primary channel based on the determination; and transmitting using the selected primary channel. The selection of the primary channel involves channel selection rules disclosed herein.
Abstract:
This disclosure describes systems, devices, apparatus, and methods, including computer programs encoded on storage media, for controlling a network with one or more access points (APs). A controller may be configured to schedule at least some resources of the one or more APs to improve network efficiency. The APs may measure and report a variety of information and statistics to the controller. The controller may determine one or more transmission parameters and one or more operations a given AP is permitted to perform during a respective time interval. The controller may communicate the one or more transmission parameters using an indication, such as a message. At least one AP associated with the controller may communicate with stations (STAs) using the one or more transmission parameters.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may identify a burst periodicity for communication bursts over one or more cells, such as secondary cells (SCells) in accordance with a multi-carrier communication scheme. The UE and the base station may determine a cell dormancy pattern for switching the SCells between an active state and a dormant state based on the burst periodicity. The base station and the UE may use one or more bandwidth parts (BWPs) for communications and may configure the UE to perform BWP switching over the SCell during the dormancy state switching operation. The base station and the UE may communicate the bursts while the SCells are in the active state and may switch the SCells between the active state and the dormant state based on the cell dormancy pattern.
