Abstract: Methods, systems, and devices for wireless communications are described that provide a number of groups of transmitters, each group of transmitters having at least one user equipment (UE), and each group of transmitters having an associated transmission opportunity (TXO) for transmission of a reference signal. A number of UEs may transmit transmissions to a base station according to non-orthogonal multiple access (NOMA) techniques in which two or more UEs concurrently transmit to the base station. Depending upon a number of UEs, a number of groups of transmitters, an overloading factor of NOMA transmissions, a system bandwidth, a time span of the reference signal TXO, or any combination thereof, a binary or non-binary orthogonal cover code (OCC) may be applied to transmitted reference signals, which the base station may use to identify reference signals from particular UEs.

Abstract: A method of multiplexing scaled numerology OFDM waveforms in an orthogonal frequency division multiplexing is presented. A first data can be encoded into a first numerology at a first set of tones and a second data can be encoded into a second numerology at second set of tones. A third data can be encoded into a guard band in such a way that the third data can be interpreted under either the first numerology or the second numerology.

Abstract: The disclosure relates in some aspects to multiplexing different types of traffic. Techniques are disclosed to facilitate puncturing one type of traffic with another type of traffic (e.g., traffic having more stringent latency and/or reliability requirements). In some aspects, these techniques mitigate potential loss of control information for the punctured traffic. In some aspects, the disclosed techniques are applicable to mobile broadband traffic and mission critical traffic.

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: Adaptive pilot signaling is disclosed in which resources allocated to pilot symbols are allowed to vary to more closely match channel conditions. User equipments (UEs) may request different pilot configurations depending on channel conditions. In one embodiment, a method includes receiving a first set of pilot symbols using a first number of resource elements during a first transmission time interval (TTI), and receiving a second set of pilot symbols using a second number of resource elements during a second TTI. In the embodiment, the first TTI and the second TTI include the same number of resource elements, and the first number of resource elements is different than the second number of resource elements.

Abstract: In a network configured to communicate over multiple services, each service may have one or more SR configurations. In embodiments, a processor may detects SR collision in which SR occasions for different services as defined by their corresponding configurations at least partially overlap. Based at least on the detected potential collisions, the processor may take action to resolve the collision

Abstract: Methods, systems, and devices for wireless communication are described for grant-free admission control to a shared channel. A base station may select an admission control parameter from a set of admission control parameters, the selected admission control parameter setting a grant-free access threshold for determining eligibility to obtain grant-free access to resources of a shared channel. The base station may transmit the selected admission control parameter to configure a user equipment (UE) with the grant-free access threshold. A UE may receive an admission control parameter from the base station, and set a grant-free access threshold based at least in part on the admission control parameter. The UE may determine eligibility to obtain grant-free access to resources of a shared channel based at least in part on the grant-free access threshold, and communicate with the base station based at least in part on the determined eligibility.

Abstract: Aspects of the present disclosure provide a wireless device that communicates with another wireless device utilizing self-contained subframes. The wireless device communicates with a scheduling entity utilizing a plurality of self-contained subframes that include a first subframe and a second subframe. Each of the self-contained subframes includes an uplink (UL) portion and a downlink (DL) portion. The wireless device further receives DL control information from the scheduling entity in the DL portion of the first subframe, and transmits UL data that includes a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe. The plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in a current mini-slot within an enhanced mobile broadband (eMBB) slot. A base station may determine that an indication message is to be transmitted within the eMBB slot. The indication message may indicate that at least a portion of the mini-slot of the eMBB slot is used for the URLLC transmission. The base station may allocate one or more resources to an indication channel in a same mini-slot as the portion of the mini-slot to be used for the URLLC transmission. The base station may transmit the indication message during the mini-slot on the indication channel using the allocated one or more resources. A UE may receive the indication channel and process at least the portion of the mini-slot based on whether the indication message is received.

Abstract: Methods, systems, and devices for wireless communication are described that support channel selection for parity bits in polar coding techniques. In some cases, an encoder or decoder of a wireless device may assign information bits, frozen bits, and parity check bits to polar channels of an encoder or decoder based on reliability metrics. The information bits may initially be assigned and based on a channel index of the first information bit, the parity check bits may be assigned to channels having higher channel indices than the first information bit. After assignment, the bits may be encoded or decoded.
