Abstract: Techniques for operator identification on a shared communication medium are disclosed. An access point may determine an operator identifier for an operator associated with an access point and configure a set of resource elements to carry an operator identifier reference signal embedded with the operator identifier. The access point may then transmit the operator identifier reference signal using the configured set of resource elements. An access terminal may receive signaling from an access point on a set of resource elements and monitor the signaling for an operator identifier reference signal. The access terminal may then determine an operator identifier for an operator associated with the access point based on the operator identifier reference signal.

Abstract: Techniques for switching a user equipment (UE) between wireless systems by first establishing a connection with a target system before disconnecting from a serving system are disclosed. In one design, the UE may initially communicate with a first wireless system (e.g., a WLAN system) of a first radio technology. The UE may receive a page to establish a connection with a second wireless system (e.g., a cellular system) of a second radio technology. The first and second wireless systems may be part of a small cell. The page may be sent by the second wireless system to the UE in response to a decision by a network entity to switch the UE from the first wireless system to the second wireless system. The UE may establish a connection with the second wireless system in response to the page and may thereafter terminate communication with the first wireless system.

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 user equipment (UE) may monitor a neighbor cell and report the result to a serving base station. Based on the report, the serving base station may identify an estimated discovery reference signal (DRS) transmission window of the neighbor cell. In some cases, the UE may estimate and report parameters of the neighbor DRS transmission window, and in other cases, the UE may make a measurement report and the base station may infer DRS transmission window parameters. The base station may then provide the UE with a DRS measurement timing configuration (DMTC) based on the estimated parameters of the neighbor cell so that the UE may monitor the neighbor cell and the serving cell in an efficient manner. For example, the UE may conserve battery life by refraining from monitoring DRS during periods when a DRS transmission is not likely.

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 communications are described. The method may include determining multiple transmission beams (e.g., beamformed directional beams) for transmission of an opportunistic or multi-beam discovery reference signal (DRS) over a shared radio frequency spectrum band. A base station may perform a listen before talk (LBT) procedure for the multiple DRS transmission beams, and transmit, based on the LBT procedure, the DRS over the shared radio frequency spectrum band using a set of the multiple transmission beams (e.g., a set that cleared an LBT procedure). In some cases, the LBT may be performed for each transmission beam, or for a union of all transmission beams, associated with the DRS transmission beams. Alternatively, the base station may determine a contention exempt transmission (CET) period for the shared spectrum band and transmit the DRS using the multiple transmission beams during CET period.

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 UE 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. The described techniques provide for transmitting, at a base station, a contention exempt broadcast paging message that includes partial paging information for a user equipment (UE), receiving a random access request message transmitted by a UE in response to the broadcast paging message, and transmitting a unicast paging message which includes complete paging information. The described techniques further provide for determining, at a base station, a first paging opportunity window (POW) and a second POW for a UE, performing a LBT procedure during the first POW, transmitting a broadcast paging message including partial paging information for the UE during the first POW, performing a second LBT procedure during the second POW, transmitting a unicast paging message to the UE during the second POW, the unicast paging message including complete paging information for the UE.

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. Wireless communications systems operating in unlicensed or shared radio frequency spectrum band may use different modes to manage hybrid automatic repeat request (HARQ) feedback. HARQ feedback may be transmitted autonomously or, in some cases, HARQ feedback may be solicited from a user equipment (UE) for one or several HARQ processes. Solicited feedback may be referred to as polled feedback and autonomous feedback may be referred to as unpolled feedback. Polled and unpolled feedback may be transmitted using different physical channels, and may be grant-based or triggered without an express grant. Buffers for polled and unpolled feedback may be separately maintained and managed. In a multicarrier configuration, uplink control information (UCI) for one or more carriers may be transmitted on a subset of configured uplink carriers. A number of carriers used for UCI may depend on operating conditions of a UE.
