Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a collision is to occur between a physical uplink control channel (PUCCH) transmission that includes a scheduling request (SR), and multiple physical uplink shared channel (PUSCH) transmissions in a slot. The UE may transmit, to a base station (BS), the PUCCH transmission or the multiple PUSCH transmissions based at least in part on determining whether the collision is to occur in the slot. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may determine a configuration for partitioning a set of sequences into multiple sequence pools associated with multiple UEs. The UE or the base station, or both, may determine a sequence pool associated with the UE based on the configuration, which may include parameters or instructions for determining the sequence pool associated with the UE. The UE or the base station, or both, may select a subset of sequences from the sequence pool associated with the UE and construct a codebook including the subset of sequences. The UE may select a sequence from the constructed codebook based on a quantity of bits of a payload and may transmit the payload to the base station using the selected sequence.

Abstract: Aspects relate to technologies and techniques for sequence-based, non-coherent wireless channel transmission of a payload on a physical uplink channel. A transmitter converts information bits of a payload to be transmitted to a decimal integer value that is, in turn, used to generate a modified maximum sequence (m-sequence) based on one or more predetermined parameters such as an m-sequence generating polynomial, a starting location in the sequence, and an initialization. The generated modified m-sequences are modulated using modulation schemes such as π/2 binary phase-shift keying and quadrature phase-shift keying for transmission on the physical uplink channel.

Abstract: Aspects relate to cross-carrier scheduling in wireless communication. A scheduling entity generates scheduling information that schedules a plurality of data transmissions to or from a user equipment (UE) on a first carrier having a first numerology. The scheduling entity then transmits the scheduling information to the UE on a second carrier having a second numerology different than (e.g., less than) the first numerology. The scheduling information is transmitted using control resources allocated based on slot indexes of a plurality of slots configured for communicating the data transmissions on the first carrier.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support configurations for grouping feedback information within a codebook. A user equipment (UE) may support one or more types of feedback. In some cases, the UE may generate subsets of feedback information within the codebook based on each type of feedback, which may increase overhead. To reduce overhead, the UE may receive signaling that indicates a configuration for grouping feedback information within a codebook. The UE may receive downlink messages that may be associated with a same set of uplink resources for transmitting a feedback message. The UE may generate a codebook to include one or more groups of feedback information in accordance with the configuration and based on the downlink messages. The UE may transmit the feedback message based on the codebook and via the set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first message indicating a UE capability to perform antenna-switching using a zero-delay gap period between successive transmissions of a sounding reference signal (SRS) using different antennas of the UE. The UE may receive a second message indicating a set of SRS parameters for the UE, the set of SRS parameters based at least in part on the UE capability. The UE may perform the successive transmissions of the SRS using the zero-delay gap period between the successive transmissions of the SRS according to the set of SRS parameters.

Abstract: Systems and method for configuring and providing uplink control information (UCI) multiplexing on physical uplink shared channel (PUSCH) transmissions are disclosed. In embodiments, a base station configures and signals, to a user equipment (UE) a plurality of sets of beta-offset values to be used by the UE for multiplexing a UCI transmission of a first priority to a PUSCH transmission of a second priority. Each set of the plurality of sets of beta-offset values is configured based on the second priority of the PUSCH transmission. In embodiments, the UE determines whether the UCI transmission of the first priority is allowed to be multiplexed to the PUSCH transmission of the second priority, and multiplexes the UCI to the PUSCH when multiplexing of the UCI and PUSCH is allowed, using a beta-offset value from the plurality of sets of beta-offset values. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for applying a mechanism to signals, from different user equipments (UEs), multiplexed for UL transmission, such that the mechanism differentiates one UE's waveform from another UE's, even if the waveforms are on the same time resources. A method that may be performed by a UE includes determining a mechanism to allow the UE to share uplink (UL) resources with at least one other UE for UL transmission, applying the mechanism to at least one of RS symbols or information symbols to be multiplexed using orthogonal frequency division multiplexing (OFDM) before performing a discrete Fourier transform (DFT) for the UL transmission, and outputting a waveform for the UL transmission after performing the DFT and an inverse fast Fourier transform (IFFT).

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may transmit a payload in transmission to the base station in a wireless communications system. The transmitter may identify a payload to include in the transmission to the base station. The transmitter may determine to transmit the transmission using an orthogonal sequence codebook or a non-orthogonal sequence codebook, based on a size of the payload, a control message from the base station to the transmitter, or a combination of these. The transmitter may then transmit the transmission to the base station based on whether the transmission is to use the orthogonal sequence codebook or the non-orthogonal sequence codebook. The transmission may be a noncoherent transmission. The transmission may be an uplink control information transmission, an uplink data transmission, a downlink control information transmission, or a downlink data transmission.
