Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied. The UE may transmit the UCI message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for avoiding collisions between hybrid automatic repeat request (HARQ) feedback transmissions and between HARQ feedback transmissions and other transmissions. In one example, a base station may configure resources for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In another example, a base station may indicate resources for a user equipment (UE) to use for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In yet another example, if a HARQ feedback transmission and another transmission are scheduled on overlapping resources, a UE may be configured to multiplex bits of the HARQ feedback transmission and the other transmission or drop the other transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may perform channel state information (CSI) estimation on multiple links (e.g., a Uu link and a sidelink) without excessive power expenditures. The UE may report a CSI processing unit (CPU) capability to a network device. The CPU capability information may include separate CPU capabilities for separate links, or a single CPU capability for multiple links. The network device, the UE, or both, may trigger CSI estimation procedures that do not exceed the reported CPU capability, or may otherwise prioritize CSI estimation procedures based on the CPU capability. The UE may then perform CSI estimation procedures according to one or more rules associated with the CPU capabilities. In some examples, such rules may be explicitly signaled to the UE, or may be included in one or more standard documents.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of common sequence pools for non-coherent transmissions according to one or more aspects. In a first aspect, a method of wireless communication includes converting, by a wireless communication device, an information bit stream to an integer value. The method also includes selecting, by the wireless communication device, a sequence from a common sequence pool based on the integer value. The common sequence pool has a nested structure of sequences which map different length information bit streams with the same most significant bit or bits to the same sequences. The method further includes transmitting, by the wireless communication device, a non-coherent transmission indicating the sequence. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving, in a first time slot, a downlink control information (DCI) message indicating second time slot or first time subslot for transmitting feedback according to a codebook size. The feedback may be transmitted in a physical uplink control channel (PUCCH) associated with a physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH). Corresponding subcarrier spacings (SCSs) for at least two of the PUCCH, the PDSCH, and the PDCCH may be different. The PUCCH may be scheduled as time subslots whereas both the PDSCH and the PDCCH may be scheduled as time slots. Further, the UE may monitor a set of one or more PDCCH monitoring occasions (PMOs) based on a mapping in accordance with a corresponding SCS, the PUCCH being scheduled as time subslots, or both, for feedback transmission.
