摘要： Methods, systems, and devices for wireless communication are described. A wireless device (e.g., an access point or a station) capable of supporting multiple chain configuration modes may dynamically select a chain configuration mode via channel analysis and energy efficiency analysis. A wireless device may monitor traffic on a wireless channel using a first chain configuration mode. The wireless device may determine an energy value associated with monitoring the traffic using the first (e.g., single) chain configuration, and further determine or infer an energy value associated with monitoring the traffic using a second (e.g., multi) chain configuration. The wireless device may perform a channel metric computation on the traffic (e.g., perform a QR decomposition of a channel matrix associated with the monitored traffic). The wireless device may then switch or select a chain configuration mode for operation based on a comparison between the determined energy values and the channel metric computation.

摘要： A method for dynamic clock and voltage scaling (DCVS) in a central processing unit (CPU) subsystem of a wireless communication device. The method may be implemented by a DCVS controller of the wireless communication device. The DCVS controller monitors data packets communicated by the CPU subsystem over a wireless local area network (WLAN) and determines one or more metrics of the data packets communicated by the CPU subsystem. The DCVS controller then dynamically configures an operating frequency of one or more hardware resources of the CPU subsystem based at least in part on the one or more metrics. The one or more metrics may include, for example, a packet rate, payload size, aggregation factor, packet size, or number of descriptors associated with the data packets.

摘要： Systems and methods are provided for coordinating power management for wireless communications devices in an independent basic service set (IBSS). An announcement traffic indication message (ATIM) coordinator receives address information for destination stations for which data is buffered for transmission at source stations. The ATIM coordinator sends an ATIM Indication frame at the end of an ATIM window, alerting any destination station to remain awake to receive buffered data. Source stations may enter power save mode during the ATIM window after transmitting the address information for the destination stations to the ATIM coordinator. Destination stations may enter power save mode after receiving a beacon at the start of the ATIM window. Source and destination stations may awaken at the end of the ATIM window to receive the ATIM Indication frame.

摘要： Systems, methods, and apparatuses for dynamic delivery traffic indication message (DTIM) implementations in a wireless communications network are described. In various examples, an access point (AP) may adjust a DTIM period over time based on various criteria, and indicate the adjustment of the DTIM period to stations being served by the AP. A station may adjust its listening period for DTIMs in response to the indication, and update the listening period based on subsequent indications. By adjusting the DTIM period over time, a wireless communications system may more effectively balance performance considerations including latency, power consumption, and synchronization associated with broadcast and/or multicast communications.

摘要： Methods, systems, and devices are described for merging two or more power save enabled independent basic service set (IBSS) networks. In one example, a method includes receiving, at a station of a first IBSS network, a first beacon from a second IBSS network, wherein the first beacon identifies a timing synchronization function (TSF) of the second IBSS network. The method may further include transmitting, by the station, a second beacon at a next target beacon transmission time (TBTT) of the first IBSS network based on a comparison of the TSF of the second IBSS network with a TSF stored by the station, wherein the second beacon identifies a TSF of the second IBSS network.

摘要： Systems and methods are provided for coordinating power management states in a wireless communications device. An access point may buffer data for a station and may then initiate transfer of the buffered data to the station when the station is considered to be in active mode. The access point may transmit each of the one stored data frames with a more data indication when at least one additional frame is buffered and with a no more data indication when no additional frames are buffered. Receipt of the terminal frame including the no more data indication allows the station to return to power save mode without waiting for any timeout period and without risking missing a transmission from the access point.

The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

The first communication operation is initiated by first communication circuitry of the wireless device. The first communication circuitry is associated with a first communication protocol. The method further includes, based on a duration of a second communication operation, performing the second communication operation associated with a second frequency band using the antenna of the wireless device. The second communication operation is initiated by second communication circuitry of the wireless device. The second communication circuitry is associated with a second communication protocol that is different than the first communication protocol. The first frequency band at least partially overlaps the second frequency band.
