Abstract: Methods and apparatus for selectively setting a network allocation vector for a subset of stations as disclosed. A method of reserving access to wireless communication medium for a plurality of wireless devices includes, transmitting a message including a first indication for a first subset of wireless devices of the plurality of wireless devices to set a network allocation vector (NAV) and further includes a second indication for a second subset of wireless devices of the plurality wireless devices to not set the NAV, so as to reserve access to the wireless medium for at least the second subset of the plurality of wireless devices.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for efficient communication between a user equipment (UE) and different entities (or functions) of a core network. Specifically, the UE may interact with a single entity (or function) of a core network (e.g., an access and mobility management function (AMF)), and messages intended for other entities (or functions) may be routed appropriately by this entity. For example, an AMF may receive a message from a UE intended for another entity (or function) of the core network, and the AMF may transmit (or route) the message to the entity (or function). Similarly, the AMF may receive a message from another entity (or function) of the core network, and the AMF may transmit (or route) the message to the UE.

Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.

Abstract: The disclosure relates in some aspects to resource requirement signaling and rate setting for communication on an unlicensed band. The disclosure also relates in some aspects to determining a token arrival rate as a function of traffic arrival information. In some aspects, the disclosed schemes may avoid traffic collisions on a resource and promote access fairness on the resource.

Abstract: Techniques are described herein to communicate policy information and policy information requests between user equipments (UEs) and a core network using control plane signaling. In some examples, non-access stratum (NAS) messages may be used to communicate policy information requests from a UE to the core network. Similarly, NAS messages may be used to communicate up-to-date policy information from the core network to the UE. In some examples, the core network may include number of functions to manage the communication of policy information with the UE. In some examples where the UE is roaming away from its home network, the core network may engage in additional signaling to pass policy information to the UE.

Abstract: Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to beacons for shared spectrum operation among multiple tiers of users. For example, a method for wireless communication is provided that includes generating, with a second tier wireless communication device of a network operating in a shared spectrum, a beacon that includes a short training field (STF), a long training field (LTF), and a beacon information field, the beacon information field including data about the network; and transmitting, from the second tier wireless communication device of the network, the beacon during a time slot of a sub-frame such that communications over the shared spectrum are coordinated based on the beacon.

Abstract: Systems, methods and devices for modifying relay operation of a wireless device are disclosed. In one aspect an apparatus for modifying relay operation of a wireless node comprises a processing system configured to generate a message requesting the wireless node to enable access point operation of the wireless node or instructing the wireless node to disable the access point operation of the wireless node. The message comprises a relay activation information element. The message comprises one or more of a field indicating a time for the wireless node to enable the access point operation or disable the access point operation and a field indicating whether the message is requesting the wireless node to enable the access point operation or instructing the wireless node to disable the access point operation.
