Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.

Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing procedure or select an overlapping uplink channel having the highest priority and drop the remaining overlapping uplink channels. The UE may determine that a first symbol period of the physical uplink scheduled channel (PUSCH) is aligned with a first symbol period of the physical uplink control channel (PUCCH) and the UE may multiplex UCI with an uplink data transmission. The UE may transmit the multiplexed UCI and uplink data on the PUSCH and drop the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH, located on the same component carrier (CC). The UE may refrain from performing UCI multiplexing if the PUSCH and the PUCCH are located on different CCs, and may simultaneously transmit UCI and uplink data over the different CCs.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a modulation and coding scheme (MCS) for an uplink communication of the UE; identify a set of beta values for uplink control information of the uplink communication according to a mapping between the set of beta values and the MCS, wherein the set of beta values is for determination of a number of resource elements or modulation symbols for the uplink control information; and transmit the uplink control information based at least in part on the set of beta values. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A method of wireless communication at a user equipment (UE) is described that may include receiving a data packet transmission over a wireless channel from a base station. The method may further include determining a set of intrinsic log likelihood ratios (LLRs) based at least in part on the data packet transmission and determining an accumulated capacity for the wireless channel based at least in part on the set of intrinsic LLRs. The method may also include determining a channel quality indicator index or a transmission rank for the wireless channel based at least in part on the accumulated capacity and transmitting a feedback message that indicates the channel quality indicator index or the transmission rank for the wireless channel to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a downlink control message from a base station scheduling multiple downlink messages and indicating a first offset for communicating a first feedback message of multiple feedback messages including feedback information for the multiple downlink messages. The UE may additionally receive, from the base station, a second offset for communicating the remaining feedback messages of the multiple feedback messages after communicating the first feedback message. The UE may transmit the first feedback message a quantity of resources equal to the first offset after receiving a first downlink message. The UE may then transmit the remaining feedback messages a quantity of resources equal to the second offset after transmitting the first feedback message. Each of the feedback messages may include feedback information for one downlink message.

Abstract: Aspects are provided allowing UEs with non-coherent or partially coherent antennas to re-interpret TPMI received in DCI into a set of TPMIs corresponding to different subbands. The UE receives a TPMI associated with at least one first antenna and at least one second antenna which are non-coherent with each other, and the UE determines a set of TPMIs including a first and second TPMI based on the received TPMI. The set of TPMIs include at least one TPMI different from the received TPMI. The UE transmits, based on the first TPMI, from the at least one first antenna within at least one first subband. The UE also transmits, based on the second TPMI, from the at least one second antenna within at least one second subband different from the at least one first subband. Thus, full power transmission based on re-interpreted TPMI with reduced DCI overhead may result.

Abstract: Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).
