  • Patent number: 11343853
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for sharing a transmission opportunity (TXOP) of a wireless channel. A first wireless local area network (WLAN) device can win a contention-based procedure to become an owner of the TXOP and determine to use the TXOP as a multi-device transmission opportunity (mTXOP). Although the first WLAN device is the owner of the mTXOP, the first WLAN device may allocate resources from the mTXOP to share with other WLAN devices. During a first portion of the mTXOP, the first WLAN device allocate subordinate transmission opportunities (sub-TXOPs) for use by other WLAN devices during a second portion of the mTXOP. The allocation of sub-TXOPs may be prepared based on fairness considerations, latency considerations, or both. In some implementations, a sub-TXOP may be allocated for a non-WLAN device, such as a wireless wide area network (WWAN) apparatus.

  • Patent number: 11337263
    Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may support parallel communications over multiple wireless links, which may benefit a wireless system in terms of throughput and latency (among other benefits). However, such systems may experience increased system complexity, which may in some cases mitigate some of the benefits provided by the parallel communication links. The described techniques provide for aggregation architectures that address various such complexities. For example, devices communicating in accordance with the described techniques may format data to be transmitted into a set of data units that are allocated to a communication link based on various factors described herein. Correspondingly, a device that receives the data packets may reorder the packets in accordance with the described techniques.

  • Patent number: 11283759
    Abstract: Methods, systems, and devices for wireless communications are described, including identifying a first attribute value associated with a first access point; receiving a second attribute value; and determining that the first attribute value associated with the first access point is the same as the received second attribute value. An attribute value may be an n-bit value, where n is an integer. The n-bit value may identify a BSS color. The n-bit value may, additionally or alternatively, indicate other BSS color information such as a BSSID, ESSID, SSID, or a combination thereof. It is helpful when devices detect BSS attribute value (e.g., BSS color, BSSID, MAC address, ESSID) overlap and notify other associated devices (e.g., STAs, APs) of this overlap so that a device may cease using an attribute value for power save or channel access decisions, and facilitate attribute value adjustment and correction to eliminate a BSS collision.
