Abstract: A wireless device may include a transceiver configured to communicate through a first link and a second link. The wireless device may be configured to indicate, through the transceiver, a number of spatial streams associated with the first link. The wireless device may include one or more radio frequency (RF) chains and may be configured to indicate a sharing capability of the one or more RF chains between the first and second links. The wireless device may be configured to perform a collision avoidance operation based on switching an RF chain from the first link to the second link. The wireless device may be configured use an RF chain on the first link based on the availability of the first link. A method of performing a sounding operation may include initiating a sounding sequence on a link based on a sounding feedback capability of a wireless device.

Abstract: Systems and methods for managing use of power of a wireless communication device configured to communicate over a plurality of radio links. A criterion is detected, and one of the plurality of radio links is selected as a selected radio link based on detecting the criterion. Operation of the selected radio link is switched from a first operating mode to a second operating mode, and operation of one or more remaining radio links of the plurality of radio links is disabled. In response to switching operation of the selected radio link to the second operating mode, the selected radio link oscillates between an awake state and an asleep state. Radio traffic information for the plurality of radio links is received, via the selected radio link, during the awake state.

Abstract: A method of providing multi-link operation channel access in a multi-link network includes initiating, by a multi-link station, a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively, receiving a first frame on the first link, suspending the second backoff countdown, decoding the first frame to identify the first frame as one of an inter-network frame, an intra-network uplink frame, or an intra-network downlink frame, and in response to identifying the first frame as the inter-network frame or the intra-network uplink frame, resuming the second backoff countdown.

Abstract: A method for providing a mode of wireless local area network (WLAN) operation includes: sending beacons from an access point (AP) in a discovery channel; sending an association request from a wireless station (STA) to the AP over the discovery channel; receiving an association response from the AP at the STA over the discovery channel in response to the association request; and after associating with the AP, switching between the discovery channel and a scheduled access channel to provide wireless communication between the AP and the STA based on a traffic condition and a bandwidth requirement.

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.

Abstract: A method and system for providing transitioning a station (STA) to an uplink multi-user (UL MU) disable mode and to a UL MU enable mode is provided. According to one embodiment, a method includes entering, with the STA, a UL MU enable mode, and determining whether to transition the STA to a UL MU disable mode based on a predetermined interrupt condition. The predetermined interrupt condition is provided by the STA in the UL MU enable mode to transition the STA to the UL MU disable mode when the STA is unable to respond to a UL MU operation.
