Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a data message to a user equipment (UE) in a data block modulated according to a modulation and coding scheme (MCS). The UE may monitor for the data block and may attempt to decode the data block. If the UE successfully receives and decodes the data block, the UE may transmit an acknowledgment (ACK) in a feedback message. If the UE unsuccessfully receives or decodes the data block, the UE may transmit a negative acknowledgement (NACK). The UE may transmit the feedback message with the ACK or NACK and a value from a codebook indicating for the base station to increase or decrease the MCS by a delta value for a following transmission or a retransmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first slot for a semi persistent scheduled (SPS) transmission on a first serving cell of multiple serving cells in a physical uplink control channel (PUCCH) group. The UE may be configured to transmit feedback information for the SPS transmission in a target slot. The UE may select either the target slot or a subsequent second slot for transmission of the feedback information based on an availability of uplink resources on the multiple serving cells in the target slot. The UE may transmit the feedback information to a base station in the target slot or the subsequent second slot based on the selection. The described techniques may enable the UE to transmit the feedback information with reduced latency, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may communicate with multiple beacon devices (e.g., road side beacons), where messages from the road side beacons may be transmitted over a sidelink communications link and may be used to determine a speed and/or location of the wireless device. In some examples, the messages may carry public safety information, location information, navigation information, or other types of information, which may be used, for example, to notify the wireless device of a nearby event, to enable navigation, or the like. When receiving messages from the road side beacons, the wireless device may report a status to a base station, which may determine a relationship between transmissions from the wireless device and predict future transmissions based on the relationship. As a result, the base station may modify communications parameters in accordance with the status of the wireless device.

Numerous other aspects are described.

Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.
