Abstract:
Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.
Abstract:
A device for communication includes a processor, a transmitter, and a receiver. The processor is configured to generate a traffic advertisement indicating availability of data to be sent to a plurality of devices. The traffic advertisement includes a unicast message addressed to a first device of the plurality of devices. The transmitter is configured to transmit the traffic advertisement during a paging window. The receiver is configured to receive, during a data transmission window that is subsequent to the paging window, a data request from a second device of the plurality of devices. The data request is responsive to the traffic advertisement. The transmitter is further configured to send first data to the second device responsive to the data request.
Abstract:
Disclosed are methods and systems for a wireless communication network including detecting a trigger to switch a serving channel at a first access point, and communicating a first channel switch message from the first access point to a second access point. The first access point may be in a downstream and/or upstream or communication flow in relation to the second access point. The process may include communicating a first Channel Switching Announcement (CSA) message from the second access point to at least one client of the second access point, where the least one client is one of a plurality of clients receiving internet connectivity through a series of communication flows including a data flow through the second access point. The process further includes revising a time to switch channel information included in the first channel switch message, where the first CSA message includes the revised time to switch channel information.
Abstract:
Systems and methods for cache invalidation, with support for different modes of cache invalidation include receiving a matchline signal (208) indicating whether there is a match between a search word and an entry of a tag array (202) of the cache. The matchline signal is latched in a latch (222) controlled by a function (220) of a single bit mismatch clock (210). A rising edge of the single bit mismatch clock is based on delay for determining a single bit mismatch between the search word and the entry of the tag array. An invalidate signal (226) for invalidating a cacheline corresponding to the entry of the tag array is output by the latch.
Abstract:
Systems and methodologies are described that facilitate maintaining consistent radio-link layer protocol (RLP) sequence numbers in the event of an RLP sequence number reset. An offset can be adjusted upon occurrence of the event to reflect a subsequent expected sequence number. The offset can be added to the RLP sequence numbers such that receiving devices and/or higher layer applications can operate without realizing the sequence number reset. Additionally, the offset can be synchronized among base stations to facilitate operability following handoff of the receiving device.
Abstract:
Various aspects are provided for low-latency wireless local area networks. In a aspect, an access point (AP) may select, from a plurality of wireless stations associated with the AP, a wireless station for the AP to poll. Each of the plurality of wireless stations may be configured to transmit on a channel in response to being polled by the AP. The AP may transmit, at a time selected by the AP, a downlink frame including polling information to the wireless station on the channel, the polling information including a permitted duration for the wireless station to access the channel. The AP may monitor during the permitted duration for the AP to receive an uplink transmission from the wireless station on the channel, the uplink transmission from the wireless station being in response to the polling information received by the wireless station.
Abstract:
A hybrid device 102, 118, 120, implementing multiple networking technologies (e.g., wireless local area network (WLAN) technologies, powerline communication technologies, Ethernet, etc.) by means of respective interfaces 114, 116, 112, 110, can be configured to execute operations to select singleton coordinating functionality in a hybrid communication network 100. In one example, a single master device (e.g., a hybrid device configured as both a registrar and a central access point (CAP)) can be selected. The hybrid device can transmit search messages to detect an existing master device and/or to identify other hybrid devices contending to become the master device. The hybrid device with the preferred device identifier is selected as the master device. In another example, operations for selecting the coordinating functionality are split into two independent stages - a CAP selection stage and a registrar selection stage. In the CAP selection stage, the hybrid device with at least a preferred device weight is configured as the CAP. In the registrar selection stage, similar operations can be executed to select the registrar. The registrar is preferrably a IEEE P1905.1 registrar. In addition to the CAP and the registrar, a standby CAP and a standby registrar may be selected. CAP 102 is coupled to network gateway 124 via a single communication medium such that it is directly connected to an external network (e.g. the Internet). A hybrid device's weight may be based on a number of WLAN communication bands.

Abstract:
Various aspects are provided for low-latency wireless local area networks (WLANs). An access point (AP) may transmit a downlink pilot signal for synchronization of the AP with one or more wireless stations. The AP may receive an uplink control block synchronized with the downlink pilot signal including a reservation for uplink transmission from a first wireless station of the one or more wireless stations. The reservation may include an uplink pilot signal and a modulated pilot signal and indicate that the first wireless station has traffic for uplink transmission to the AP. The AP may schedule the first wireless station for uplink transmission during a traffic block after the uplink control block. The AP may estimate a wireless channel to the first wireless station based on the pilot signal and the modulated pilot signal. Other low-latency aspects apply to WLANs in which the AP and associated wireless stations are synchronized.
