Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may receive a control signal from a base station on resources of a first narrowband region. The UE may then identify a second narrowband region based on the 5 control signal. In some cases a broadband carrier may be divided into an indexed set of narrowband regions, and the UE may identify an index using information contained in (implicitly or explicitly) in the control signal. The UE may communicate with the base station on resources of the second narrowband region. For example, a UE may receive a system information block (SIB) or a paging message, and perform a random access procedure 0 using narrowband resources selected based on the SIB or paging message. 115-b 105-b Control Signal 510-a __ 505 Determine Narrowband Resource For RACH Determine Narrowband Resource For RACH 510-b 515N1 RACH preamble 520-a _____ _____ 5Determine Narrowband Determine Narrowband Resource For Response Resource For Responsek 520-b RACH Response Paging Message 525

Abstract: Methods and apparatuses are described for wireless communications. A first method includes transmitting a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal to a wireless node in a licensed spectrum, and transmitting, concurrently with the transmission of the first OFDMA communications signal, a second OFDMA communications signal to the wireless node in an unlicensed spectrum. A second method includes receiving a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal from a wireless node in a licensed spectrum, and receiving, concurrently with the reception of the first OFDMA communications signal, a second OFDMA communication signal from the wireless node in an unlicensed spectrum. A third method includes generating a periodic gating interval for a cellular downlink in an unlicensed spectrum, and synchronizing at least one boundary of the periodic gating interval with at least one boundary of a periodic frame structure associated with a primary component carrier of the cellular downlink.

Abstract: In aspects, an initial access procedure may include a random access channel (RACH) procedure. Thereby, a user equipment (UE) may transmit, to a base station, a random access channel preamble over a first bandwidth of a system bandwidth that is less than the system bandwidth, receive, from the base station after transmitting the random access channel preamble, a random access channel response over the first bandwidth, receive, from the base station after transmitting the random access channel preamble, one or more reference signals over one or more portions of a second bandwidth of the system bandwidth, the second bandwidth being wider than the first bandwidth, the one or more portions of the second bandwidth being different than the first bandwidth, the one or more reference signals being usable for determining a beam to be used for data communication over the second bandwidth, and receive, from the base station, a physical downlink shared channel (PDSCH) over the second bandwidth via the beam based on the one or more reference signals.

Abstract: A data structure for managing user equipment communications in a wireless communication system is presented. In some examples, the data structure may include one or more resource element blocks into which a frequency bandwidth of a downlink channel is divided within a symbol that defines a transmission time interval in a downlink subframe. Furthermore, the data structure may include a control region and a data region within at least one resource element block of the one or more resource element blocks. Additionally, the data structure may include a downlink resource grant, located within the control region, for a user equipment served by the downlink channel. In an additional aspect, a network entity and method for generating the example data structure are provided.

Abstract: In aspects, a user equipment may be configured to determine a preconfigured frequency band that is less than an available system bandwidth. The UE may be further configured to perform an initial access procedure with a base station using the preconfigured frequency band. The initial access procedure may include a random access channel (RACH) procedure.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). Additionally, certain aspects of the present disclosure provide techniques for managing communications in a wireless communication system, for example, by using enhanced downlink control channels.

Abstract: Techniques are described for wireless communications. A first subframe structure having a first subframe duration for communicating in a first carrier may be determined. A second subframe structure having a second subframe duration for communicating in a second carrier may also be determined. At least the second subframe structure having the second subframe duration may be used to communicate with at least one node.
