Abstract: A device (e.g. a wireless communication device) may determine, according to a set of guidelines, a list that includes system information to be requested by the device as part of a system information request procedure. The device may determine whether to combine the system information request with an additional request associated with a random access procedure (RACH). In response to determining that the requests are to be combined, the device may initiate a unified RACH that combines the system information request and the additional request. The decision to combine the requests may be based on the type of the additional request, whether the list has been completed by the time the additional request is to be issued, and/or additional factors associated with wireless communications of the device. The system information request may be an OnDemand system information block request, and the RACH may be contention-based or contention-free.

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.
