Abstract: A connection may be established between a base station and a user equipment (UE) using a radio frequency shared by multiple network operating entities. Resources (e.g., a frame) may be divided into exclusive, prioritized, and opportunistic sub-intervals for a given network operating entity coexisting within the shared radio frequency spectrum. Additionally, a set of low latency sub-intervals (e.g., reserved resources) may be designated for use by the network operating entity for mission critical (MiCr) and/or autonomous uplink transmissions. The network operating entity may indicate timing information for low latency sub-intervals during a sub-interval for exclusive use by the network operating entity. The UE may then transmit MiCr and/or autonomous uplink messages using the low latency intervals without performing a medium sensing procedure. In some cases, the sub-intervals for MiCr and autonomous uplink transmissions may be for exclusive use by the network operating entity.

Abstract: Methods, systems, and devices for wireless communication are described that provide for discovery of resources in a wireless communications system. The wireless communications system supports operations for multiple network operating entities that share a radio frequency spectrum. To discover and perform synchronization with the wireless communications system, a common preamble may be transmitted by nodes associated with multiple network operating entities. The common preamble may include information common to each of the multiple network operating entities which may be used by a device to identify neighboring wireless nodes, available network operating entities, or sub-intervals designated for prioritized or opportunistic use by one or more network operating entities.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence or discovery signal. The signature sequence may be used for resource reservation, scheduling, and coordination among disparate systems operating on a shared spectrum. Other aspects, embodiments, and features are also claimed and described.

Abstract: In order to provide a generic access rule, the present disclosure proposes a new potential set of adaptivity rules for LBE based on LBT. The generic access rule of the present disclosure provides LTE-U and Wi-Fi coexistence and DL/UL coexistence in both LTE-U and Wi-Fi. The apparatus receives, from the first master device, a resource allocation for communicating with the second master device. The apparatus also determines a type of CCA procedure to perform before communicating with the second master device on an unlicensed channel. The apparatus further performs a CCA procedure to obtain a transmission opportunity based on the determining, the CCA procedure being one of an ICCA procedure or an ECCA procedure. In addition, the apparatus transmit data to the second master device in accordance with the resource allocation on the unlicensed channel when the transmission opportunity is obtained.

Abstract: Techniques are described for wireless communication. One method includes determining a set of uplink (UL) component carriers (CCs) to use for a user equipment (UE). The set of UL CCs may include at least one UL CC in a first radio frequency spectrum band and at least one UL CC in a second radio frequency spectrum band. The method further includes identifying, for a subframe, uplink control information (UCI) due for transmission, the UCI associated with one or more CCs, and limiting available UL CCs for transmission of the UCI to the at least one UL CC in the first radio frequency spectrum band.

Abstract: Design of channel usage beacon signals (CUBS) in cooperative networks is disclosed. After detecting a clear channel assessment (CCA), a transmitter selects a configuration of a CUBS associated with the transmitter based on the CCA opportunity assigned to the network. The configuration of the CUBS associated with the transmitter may include a set of frequency subcarriers for CUBS transmissions. The transmitter transmits the CUBS according to transmission characteristics based on the CCA opportunity. In additional aspects, randomization may be introduced into the frequency subcarrier allocations of CUBS configurations where the transmitter receives assignment of virtual frequency subcarriers for CUBS transmissions and maps the virtual subcarrier to physical frequency subcarriers for CUBS transmission. Additional aspects allow for pattern offset values to be determined independently from the transmitter cell identifier. In such aspects, the assigned pattern offsets may be cell identifier-independent, while others may be cell identifier-dependent.

Abstract: Methods, apparatuses, systems, and devices are described for wireless communication. In one method, a control format indicator value for a frame may be received over a physical carrier in a shared spectrum. Based on the control format indicator value, a number of subframes of the frame to be used by a base station for downlink transmissions over the physical carrier may be determined. The control format indicator value may indicate an end of transmission, if data is to be transmitted during the frame, a number of subframes to be used for transmission, or whether the current subframe is the final subframe used for transmission. In some cases, a user equipment (UE) may use the control format indicator value to determine a sleep schedule. Further, ACK/NACK transmissions by a UE may be scheduled based on the control format indicator value.

Abstract: Methods and apparatus for paging comprise receiving data destined for a UE. The methods and apparatus further comprise determining a short identity for the UE relative to a longer global user equipment identity and identifying a MIB transmission based on a short identity. Moreover, the methods and apparatus comprise activating a bit within a slot of the MIB transmission to indicate that the user equipment listen for a page in order to receive the data and broadcasting the MIB. In other aspects, methods and apparatus for receiving a page comprise entering an idle state while camped on a cell. The methods and apparatus further comprise waking up from the idle state to monitor a slot of a MIB for a paging indication. Moreover, the methods and apparatus comprise recognizing the paging indication in the monitored slot of the MIB, determining a paging window based on correlation information in a SIB and waking up to listen for a page during the paging window.

Abstract: UE that are able to cancel interference from CRS, a PDSCH, a PDCCH, or a PCFICH may do so without explicitly signaling the capability to the serving eNB. The serving eNB may transmit to the UE a plurality of cell identifiers to indicate from which cells interference should be canceled. The UE receives CRS, PDSCH, PDCCH, or PCFICH from the serving eNB and cancels CRS, PDSCH, PDCCH, or PCFICH interference, respectively from the signal received from the eNB. The UE cancels the interference from the cells that correspond to the cell identifiers. The UE may then transmit a report to the eNB with a quality measurement without the interference.
