Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may attempt to access a network at a local area network access point without prior context information. The access point may be a hotspot operating in unlicensed spectrum according to a Long Term Evolution (LTE)-based standard. The UE may be unable to determine if it is authorized to access the network, so the UE may attempt to obtain system information that provides a list of service providers supported by the network. The UE may then determine whether it has credentials for a supported service provider, and the UE may access the network using those credentials when a supported service provider is recognized. Other broadcast messages may provide information about system information for supported service providers. A UE that is unable to access the network using stored credentials may attempt access using a random access channel procedure.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a control message during a special subframe of a radio frame. The UE may determine a payload size of the control message according to a radio resource configuration, or the UE may determine a payload size based on a number of bits associated with information to be sent in the control message. The UE may identify uplink resources of the special subframe to use for the control message based on explicit signaling or implicitly based on information to be sent in the control message. Designated resources for control message transmissions in a special subframe may remain the same or may change in subsequent transmission opportunities. The UE may determine to use the same or different resources of a special subframe in a subsequent transmission opportunity depending on when the UE receives downlink messages.

Abstract: Techniques for reservation coordination on a shared communication medium are disclosed. An access point, for example, may contend for access to a communication medium, and transmit a channel reservation message in accordance with a first Radio Access Technology (RAT) to reserve the communication medium for a transmission opportunity (TXOP) duration based on the contending. The access point may then transmit, during the reserved TXOP duration, a reservation coordination signal in accordance with a second RAT to convey reservation coordination information associated with the reserved TXOP duration.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a semi-static resource allocation for a device (e.g., a user equipment (UE) ). The resource allocation may be associated with autonomous transmissions from the device in an unlicensed radio frequency spectrum band. The base station may generate and provide a message for transmission to the device. The message may convey an indication of the resource allocation. The device may receive the message and use the resource allocation to identify a transmission schedule for the autonomous transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a measurement scheme or uplink mode and then transmit an indication of the scheme or uplink mode to an associated user equipment (UE). The base station may identify a set of hidden nodes for the U E and configure the UE for autonomous or grant-based uplink transmissions accordingly. A UE may initiate a channel clearance scheme by transmitting a first channel clearance signal (e.g., a request-to-send message), which may include a UE identifier before transmitting an uplink message in the unlicensed radio frequency spectrum band. In response, the base station may transmit a second channel clearance signal (e.g., a clear-to-send message). In some cases, the second channel clearance signal may include control information or may be transmitted at a power level that is based on a characteristic of the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) or a base station may select an autonomous uplink mode, which may support unscheduled uplink transmissions in an unlicensed radio frequency spectrum band. A UE may initiate a channel clearance scheme by transmitting a first channel clearance signal (e.g., a request-to-send message), which may include a UE identifier, to a base station, before transmitting an uplink message in the unlicensed radio frequency spectrum band. In response, the base station may transmit a second channel clearance signal (e.g., a clear-to-send message) to the UE which, in some cases, may include control information. In some examples, the second channel clearance signal may be transmitted at a power level that is based on a characteristic of the UE. After receiving the second channel clearance signal, the UE may transmit an uplink message in the autonomous uplink mode.
