Abstract: Methods and apparatuses for wireless communication are provided. A transmitting apparatus receives an indication to use multiple subframes to send uplink control information, codes the uplink control information over the multiple subframes based on the indication, and sends the coded uplink control information via the multiple subframes. Sending the coded uplink control information includes transmitting acknowledgement information (ACK) of a current downlink-centric self-contained subframe in an uplink acknowledgement portion of the current downlink-centric self-contained subframe, bundling ACK bits of multiple downlink-centric self-contained subframes and encoding the bundled ACK bits to generate parity acknowledgement bits associated with systematic acknowledgement bits, transmitting the systematic acknowledgement bits in each uplink acknowledgement portion of the multiple downlink-centric self-contained subframes, and transmitting the parity acknowledgement bits associated with the acknowledgement information bits of the multiple downlink-centric self-contained subframes in an uplink-centric self-contained subframe that is sequentially subsequent to the multiple downlink-centric self-contained subframes.

Abstract: Methods, systems, and devices for wireless communication are described for a data channel-referenced resource allocation for a control channel. In an implementation, a user equipment (UE) may identify, for a transmission time interval (TTI), a first uplink resource allocation to the UE of a first channel. The UE may determine, based at least in part on the first uplink resource allocation of the first channel, a second uplink resource allocation of a second channel to the UE. The UE may transmit, during the TTI, the first channel and the second channel.

Abstract: Methods, systems, and devices for wireless communication are described A user equipment (UE) and a base station may support switching from one waveform to another on uplink channels. For example, a UE and a base station may utilize both frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveforms based on channel conditions and other factors. In some examples, a UE may switch for some uplink channels, and use a single waveform for other channels. For example, switching waveforms for channels that utilize frequency domain code division multiplexing (CDM) channel may interrupt the orthogonality of multiplexed transmissions. A UE may transition from one waveform to another either autonomously or based on an explicit indication from a base station. If a UE switches autonomously, it may send an indication of the transition to the serving base station.

Abstract: Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

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 the 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: Wireless communication devices are adapted to facilitate multiple synchronization channels within a single carrier. In some examples, an apparatus for wireless communication may transmit a first synchronization channel at a first frequency in a carrier bandwidth, and at least one additional synchronization channel at a different respective frequency in the carrier bandwidth. In some examples, an apparatus for wireless communication may scan a carrier bandwidth for one of a plurality of synchronization channels conveyed at different respective frequencies in the carrier bandwidth, and discover a synchronization channel from among the plurality of synchronization channels. The apparatus may further receive information conveyed over the discovered synchronization channel and utilize the information to access the carrier. Other aspects, embodiments, and features are also included.

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: Aspects of the present disclosure provide for a network assisted grantless data transmission method operable in a wireless communication network. A wireless device may transmit grantless data without requesting a scheduling entity to grant and schedule network resources prior to the grantless data transmission. A scheduling entity determines interference tolerance information of a plurality of uplink channels, wherein the interference tolerance information is configured to individually indicate an availability of each of the plurality of uplink channels for grantless uplink data transmission. The scheduling entity broadcasts the interference tolerance information to one or more subordinate entities or wireless devices.
