Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) or a receiving UE may receive a message indicating a set of formats for a sidelink feedback channel. The transmitting UE may transmit a sidelink control message and a sidelink data message to the receiving UE, and the receiving UE may generate feedback for the sidelink data message. The receiving UE may transmit, to the transmitting UE, a sidelink feedback message including the feedback using a set of resources of the sidelink feedback channel based on a format of the set of formats. The format may correspond to a time domain configuration, a frequency domain configuration, or both, that indicates the set of resources. In some examples, the receiving UE may receive (e.g., from the base station or the transmitting UE an indication of a format to use for the feedback message.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A user equipment (UE) may receive a first data message in a sub-slot of a slot and in a sub-channel of a sidelink data channel. The UE may select a resource of a sidelink feedback channel based on a first index associated with the slot and a second index associated with the sub-slot within one or more slots comprising the slot. Additionally or alternatively, the UE may select a resource of a sidelink feedback channel from periodic resources having a slot-based periodicity based on an index associated with the sub-slot within one or more slots comprising the slot. The UE may transmit a feedback message associated with the first data message according to the selected resource.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may associate a first port and a second port each with a set of antenna elements based on a first and a second linear precoding vector, where the phases of the ports are coherent. The base station may generate coefficients indicating a first combination and a second combination of a first data set for a first user equipment (UE) and a second data set for a second UE. In some cases, the base station may apply the first linear precoding vector to the first combination, apply the second linear precoding vector to the second combination, and transmit the first combination using a first transmission beam corresponding to the first port and the second combination using a second transmission beam corresponding to the second port to the first and second UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying an offset between a start of a frame on a first component carrier and a start of a frame on a second component carrier, wherein the first component carrier is one of a primary cell (PCell) or a secondary cell (SCell), and wherein the second component carrier is the other of the PCell or the SCell; determine that a slot on the first component carrier is aligned with a slot on the second component carrier; identify the slot on the second component carrier in accordance with the offset; and communicate on the first component carrier or the second component carrier based at least in part on the start of the slot on the second component carrier. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may transmit a first transmission of a transport block to a user equipment (UE). The UE may decode the received transport block and may receive control signaling indicating that a second wireless device is to transmit a second transmission of the transport block based on decoding the transport block. The UE may perform interference cancellation for the second transmission of the transport block from the second wireless device based on receiving the control signaling and may receive a third transmission based on performing the interference cancellation, where a first resource of the second transmission overlaps in time, frequency, or both with a second resource of the third transmission.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced sidelink carrier aggregation feedback operations. In a first aspect, a method of wireless communication includes receiving, by a wireless communication device, a sidelink shared channel transmission via a first component carrier. The method also includes obtaining, by the wireless communication device, a feedback resource indication. The method further includes transmitting, by the wireless communication device, a sidelink channel feedback transmission in a sidelink channel feedback transmission resource via a second component carrier different from the first component carrier. The sidelink channel feedback transmission resource is determined based on the feedback resource indication, and the sidelink channel feedback transmission indicates feedback data for the sidelink shared channel transmission. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.
