Abstract: Methods and apparatuses for channel sounding reports may be used in wireless local area network (WLAN) systems. A station (STA) may receive, from an access point (AP), a beacon frame. The STA may receive, from the AP, a null data packet (NDP) announcement (NDPA) frame including an indication of subchannels for measuring channel characteristics. The STA may receive, from the AP, an NDP frame. The STA may transmit, to the AP, a feedback report frame including channel state information (CSI) feedback, wherein the CSI feedback is based on measurements that the STA performed on the received NDP frame using the indicated subchannels for measuring channel characteristics. The beacon frame may include indications of punctured subchannel(s) and subchannel(s) that is not punctured, which may be indicated as a disabled subchannel bitmap. The subchannels for measuring channel characteristics may be equal to or a subset of the subchannel(s) that is not punctured.

Abstract: A wireless station (STA) for parameterized spatial reuse (PSR) operation. The STA may receive, from a first access point (AP) that the STA is not associated with, a trigger frame. The trigger frame includes a signal (SIG) field that includes a PSR field. The PSR field includes a plurality of subfields each corresponding to a respective subchannel associated with the trigger frame. This information includes transmission power level information. The STA may then determine, for each subchannel, using the transmission power level information, transmission power upper bounds for each of the subchannels.

Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.

Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

Abstract: Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.

Abstract: A federated learning (FL) and/or a distributed machine learning (ML) model sharing process may be implemented in a wireless network. An access point (AP), station (STA), or the like may provide a FL announcement message indicating that a FL or ML process is in being utilized. A STA receiving the announcement message may provide a FL/ML support frame indicating its participation in FL model sharing. The STA may comprise a local FL model executable on the STA. The STA may update its local FL model based on information in the FL announcement message. The STA may update its local FL model based on information received from other STAs in the network. The FL announcement message may comprise a schedule, and the STA may be configured to train its local FL model in accordance with the schedule. The sharing model process may be implemented in a wireless local area network.

Abstract: Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.
