Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive data or control signaling on one or more first sidelink channels on a set of sidelink carriers. The UE may receive data or control signaling on one or more second sidelink channels on the set of sidelink carriers. The UE may transmit hybrid automatic repeat request (HARQ) feedback corresponding to the data or control signaling on the one or more first sidelink channels and the data or control signaling on the one or more second sidelink channels. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message that comprises scheduling information for a downlink message to be received by the UE and an uplink message to be transmitted by the UE. The UE may determine first frequency information for the downlink message and second frequency information for the uplink message based at least in part on the scheduling information, a first bitfield size associated with resource allocation for a first bandwidth part associated with the downlink message, and a second bitfield size associated with resource allocation for a second bandwidth part width associated with the uplink message. The UE may communicate the uplink message and the downlink message with the base station according to the first frequency information and the second frequency information.

Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to determine an operation state for a user equipment (UE) that corresponds to how the UE applies a preemption indication. The base station may indicate the operation state to the UE using a parameter of a configuration message. The base station may transmit a grant indicating time-frequency resources scheduled for the UE. The UE may identify a priority of a channel associated with the scheduled resources. The base station may determine a number of scheduled resources to be preempted or canceled and may indicate these resources to the UE using a preemption indication. The UE may determine remaining time-frequency resources based on the preemption indication, the priority of the channels, the operation state, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be scheduled to send uplink data to a base station using a particular transmission length provided by the base station. The UE may send multiple repetitions of the uplink data to the base station using transmissions that have varying lengths. The UE may determine a transmit power based on the length provided by the base station and use that transmit power for transmitting the repetitions, regardless of the actual lengths of the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with quasi co-located (QCL) associations between a physical uplink control channel and a sounding reference signal (SRS) transmission for at least one time and frequency domain channel parameter. The UE may transmit, in accordance with the QCL association, a control channel transmission via the physical uplink control channel using an antenna port that is quasi co-located with at least one antenna port for transmitting the SRS transmission and transmit, in accordance with the QCL association, the SRS transmission via the at least one antenna port. In another example, the base station may configure the UE with an antenna port association between an SRS transmission and a physical uplink control channel. The UE may transmit the SRS transmission and a control channel transmission in accordance with the antenna port association.

Abstract: This disclosure describes methods, devices, and systems for techniques related to wireless communications, and more particularly uplink transmissions on one or more of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH). Generally, the described techniques support handling collisions between PUSCH repetitions and a PUCCH transmission. A user equipment (UE) may identify that uplink control information (UCI) is scheduled for transmission via an uplink control transmission that overlaps with multiple repetitions of an uplink data transmission. The UE may determine, for each of the multiple repetitions, a quantity of resources available for carrying multiplexed uplink control information, generate encoded UCI by encoding the UCI based on the quantity of resources available in each of the multiple repetitions, and multiplex the encoded UCI on at least a portion of the multiple repetitions based on the quantity of resources available in each of the multiple repetitions.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) having partially coherent antennas may be configured for simultaneous transmissions on groups of antennas. To achieve the benefits of simultaneous transmissions using groups of antenna that are partially coherent, without having the transmissions affect each other, the UE may apply a hybrid closed-loop multiple-input multiple-output (MIMO) scheme among each antenna in the antenna groups where phase coherence can be maintained Following the hybrid closed-loop MIMO scheme, the UE may apply a transparent diversity scheme across each antenna of the groups. Alternatively, the UE may first apply the transparent diversity scheme and next apply the hybrid closed-loop MIMO scheme. By applying a hybrid closed-loop MIMO scheme, and a transparent diversity scheme, the UE may fully realize its resources and contribute to an improved spatial diversity for a MIMO system.

Abstract: Methods, systems, and devices for wireless communication at a first user equipment (UE) are described. A UE may receive a control signal indicating a set of durations. A duration of the set of durations may be scheduled for uplink resources and additional resources including downlink resources, flexible resources, or both. The UE may further receive an indication of a slot format configuration permitting sidelink communications on the uplink resources during the duration scheduled for the uplink resources and the additional resources. Upon identifying that sidelink communications are permitted, the UE may transmit a sidelink transmission using the uplink resources and during the duration.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to adjust a random access message that is transmitted to a base station in an asynchronous uplink transmission. The UE may use a constrained mapping of time and frequency resources for the random access message or transmit all portions of the message in a continuous transmission. The UE may also adjust the timing of the portions of the message. The base station may use a portion of the message, such as a preamble, to perform channel estimation for another portion of the message, such as a payload, to improve decoding of the transmitted message. Additionally, the UE may configure a waveform of the message to improve the continuous transmission of the message, for example by reducing interference between portions of the message.
