    Abstract: At times a UE may have a data transmission that needs to extend beyond a resource grant in an ULRB portion of a slot. The UE may receive resource region reservation information from a base station and determine when to extend an UL transmission from the ULRB portion of a slot into the ULCB portion of the slot based resource region reservation information. The resource region reservation information may indicate ULCB resources which are reserved for PUCCH, PRACH, PUSCH, SRS, or other transmissions. The UE may determine to refrain from extending the data transmission into the ULCB when at least a portion of the data transmission would overlap reserved resources as indicated by the resource region reservation information.

    Abstract: Certain aspects of the present disclosure provide a method for wireless communications in a wireless network via a radio access technology. The method generally includes determining dimensions of a matrix to be used for performing interleaving of modulated symbols carrying bits, from a plurality of code blocks, for mapping into bundles of resource elements, in an orthogonal frequency division multiplexed (OFDM) system, based, at least in part, on one of a ratio of a code block size to a number of bits to be mapped into each resource element or the number of bits to be mapped into each resource element, performing the interleaving of the modulated symbols, according to the matrix having the determined dimensions, and transmitting the interleaved modulated symbols in the wireless network via the radio access technology. Other aspects, embodiments, and features are also described and claimed.

    Abstract: Certain aspects of the present disclosure provide techniques for processing reference and data signals for uplink transmission. A method is provided for wireless communications. The method generally includes obtaining different sets of samples for at least one of: a data signal or a reference signal; spreading the different sets of samples for the at least one data signal or reference signal using separate discrete Fourier transform (DFT) processing blocks; interlacing the spreaded sets of samples by assigning the spreaded sets of samples from each of the separate DFT processing blocks to equally spaced tones; and transmitting the at least one data signal or reference signal on the assigned tones in an orthogonal frequency division multiplexed (OFDM) symbol.

    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: Methods and apparatuses for demodulation reference signal (DMRS) transmission are described. At a user equipment (UE), a method and apparatus may include receiving, from a network entity, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the network entity on the channel in accordance with the DMRS pattern. At a network entity, a method and apparatus may include transmitting, to a UE, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the UE on the channel in accordance with the DMRS pattern.

    Abstract: A BS may transmit a first signal using a first group of one or more tones, transmit a second signal using a second group of one or more tones, and transmit a third signal using a third group of one or more tones in a GB between the first and second groups of tones. In one example, the transmitting comprises controlling a transmit power of at least one tone of the third group of one or more tones in the GB. The at least one tone of the third group of tones is on a different frequency grid than the first group of one or more tones or the second group of one or more tones. A UE may perform corresponding transmit power control operations for UL transmissions in a GB.
