Abstract: Techniques for wireless device roaming are disclosed. These techniques include identifying a wireless client entity for roaming from a first infrastructure entity to a second infrastructure entity. The techniques further include agreeing, between the client entity and the first infrastructure entity, on one or more roaming conditions defined using transition parameters for transition of a first data flow for the client entity from the first infrastructure entity to the second infrastructure entity, the one or more transition parameters including a sequence number relating to the dataflow. The techniques further include determining that a first condition defined in terms of a transition parameter of the agreed one or more roaming conditions is met, and, based on the determining, transitioning from providing the first dataflow from the first infrastructure entity to the client entity to providing the first data flow from the second infrastructure entity to the client entity.

Abstract: Systems and techniques for mitigating interference in multi-access point coordination (MAPC) deployments are described. An example technique includes obtaining interference information associated with at least one device interfering with multi-access point communication. The interference information includes at least one of an indication of a frequency of occurrence of interference with the multi-access point communication or an indication of a duration of the interference. Resource allocation is performed for the multi-access point communication, based on the interference information.

Abstract: Techniques and systems for enhancing transmit opportunity (TXOP) sharing for multi-access point coordination (MAPC) are described. An example technique includes obtaining, for each access point (AP) of a plurality of APs in a MAPC group, historical mobility information of client stations (STAs) associated with the AP. A number of the client STAs associated with each AP that satisfies a mobility criteria is determined based on the historical mobility information. A determination of whether to enable TXOP sharing is made for each AP and an indication of the determination is transmitted to the AP. Another technique includes estimating traffic demand for a first set of client STAs associated with an AP. A second set of client STAs to make available for TXOP sharing is determined. Signal strength information associated with a communication link between each client STA in the second set and the AP is transmitted.

Abstract: Techniques for delegated peer-to-peer scheduling are provided. A first peer-to-peer device determines one or more wireless channels allocated for peer-to-peer communication, and receives a request indicating a set of transmission characteristics from a second peer-to-peer device that uses the first peer-to-peer device as a communications proxy. The first peer-to-peer device schedules wireless resources of the one or more wireless channels to a plurality of peer-to-peer devices based at least in part on the set of transmission characteristics, and performs peer-to-peer communications with the second peer-to-peer device in accordance with the scheduled wireless resources.

Abstract: Dynamic spectrum access mode based on station capabilities is provided by categorizing functionalities of Access Points (APs) and stations (STA) in a wireless network; identifying interference induced by external signaling devices on channels in the wireless network; calculating an impact factor of the interference based on proximity of the external signaling devices to the wireless network, a pattern of the external signaling devices, and an extent of overlap with frequencies used by the external signaling devices and the wireless network; and in response to identifying a given STA that is paired with a given AP in the wireless network, wherein the given STA and the given AP are both categorized as being capable of both multilink communications and preamble puncturing, assigning network resources for the given STA to communicate with the given AP via one of multilink communications or preamble puncturing based on the impact factor of the interference.

Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Radar is detected on a first subchannel of the plurality of subchannels. It is determined to puncture the first subchannel, based on the detecting the radar on the first subchannel and based on one or more puncturing factors. The first subchannel is punctured, the puncturing comprising muting one or more subcarriers on the first subchannel.

Abstract: Techniques are provided for optimizing performance of a multi-link device (MLD). In one embodiment, a controller receives information about a filter response for a first multi-link device (MLD, determines, based on the information about the filter response, a filtering transitional region of the first MLD indicating a range of frequencies where there is energy leakage due to the first MLD device operating in a simultaneous transmission and reception (STR) mode, determines cost metrics for a plurality of channels by identifying a STR and non-STR (NSTR) ratio for each of the plurality of channels, and assigns, based on the filtering transitional region and the cost metrics, a first radio of an access point (AP) to one of the plurality of channels to enable the first MLD to operate in the STR mode when communicating with the first radio.
