Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit control information using a narrowband common control region that occupies a portion of a system bandwidth. In some cases, data may be multiplexed during the same time period in tones that are not used by the common control region. The base station may transmit control region configuration information to one or more user equipment (UE) devices such as the bandwidth, central frequency, and multiplexing status of the common control region. In some cases, the common control region may be divided into subbands, and different UEs may be assigned to monitor different subbands. Unassigned UEs may monitor a default anchor subband.

Abstract: Wireless communications systems and methods related to decoupling uplink latency using common uplink (UL) burst in Time Division Duplex (TDD) sub-frame structure are disclosed. User equipment (UE) can transmit to a base station a common UL burst in each sub-frame communicated between UE and the base station, wherein he common UL burst comprises at least one of: a physical layer (PHY) acknowledgement (ACK), a scheduling request (SR), a buffer status report (BSR), or a sounding reference signal (SRS). UE can be further configured to transmit scheduled UL payload data in at least one common UL burst of at least one sub-frame communicated between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: The disclosure provides for an apparatus for wireless communications using carrier aggregation comprised of multiple carrier components. The apparatus can include a processor configured to generate one or more instances of a codeword from a data payload. In an aspect, the apparatus also includes a modulator configured to modulate the one or more instances of the codeword onto the multiple carrier components for transmission. In an aspect, the apparatus also includes a resource manager configured to provide the processor with a virtual carrier space comprising a logical carrier having a contiguous bandwidth equivalent to the aggregated bandwidth of the multiple carrier components. In an aspect, the process may be further configured to interleave at least one of the codeword instances across the multiple carrier components. In an aspect, the modulator may be configured to modulate the codeword instance onto the multiple carrier components in accordance to the interleaving.

Abstract: Wireless communications systems, methods, and techniques related to signaling and determining slot and mini-slot structures are provided. A first wireless communication device transmits a first signal according to a first numerology including at least a first tone spacing. The first signal indicates a second numerology including at least a second tone spacing. The first wireless communication device transmits a second signal according to the second numerology. The first signal includes a physical broadcast channel (PBCH) signal. The second numerology is independent from the first numerology. Different slot/mini-slot structures may be utilized for varying channel types to support mixed numerology arrangements. Embodiments may utilize single and varied slot structures; single slot structures may be decoupled from transmission numerology and varied slot structures may be defined based on reference numerology. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. In applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal to the base station, which characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. The base station may form the beam to the UE based on the uplink channel information obtained from the SRS. As the downlink channel changes the base station needs updated information to maintain its beamforming, meaning it needs a new SRS. Transmission of the SRS takes resources; to minimize this, the UE or the base station can determine a period during which the downlink channel will predictably remain coherent and set up a schedule for sending SRS. Alternatively, the UE or the base station can determine on demand that the channel is losing coherence and initiate an on demand SRS.

Abstract: The disclosure relates in some aspects to a scalable transmission time interval (TTI) and hybrid automatic repeat request (HARQ) design. The TTI is scalable to, for example, achieve latency and/or efficiency tradeoffs for different types of traffic (e.g., mission critical traffic versus traffic with more relaxed latency requirements). In the event a longer TTI is employed, various techniques are disclosed for ensuring a fast turn-around HARQ, thereby maintaining a high level of communication performance.

Abstract: A wireless network may provide system information by either a fixed periodic broadcast or broad-beam transmission or in response to a request by a user equipment (UE). The wireless network may broadcast (or broad-beam transmit) a signal that indicates to the UEs within a cell or zone coverage area that system information is to be transmitted on a fixed periodic schedule or in response to a request sent by one or more UEs.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. Frame formats are disclosed in which control signals are transmitted at different bandwidths than data signals. Receiver architectures for receiving the signaling formats are disclosed. A receiver can receive a relatively narrowband control signal while consuming a relatively low power and then dynamically adjust characteristics of various components to receive a data signal at a higher bandwidth while consuming a relatively higher power.
