Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating a semi-persistent scheduling configuration. The UE may monitor for a downlink data transmission based at least in part on the semi-persistent scheduling configuration. The UE may determine that an uplink feedback message corresponding to the downlink data transmission is scheduled to be transmitted by the UE in a first uplink control resource that at least partially overlaps with a downlink resource, a flexible resource, or both. The UE may identify, based at least in part on the overlap, a second uplink control resource to use for transmitting the uplink feedback message.

Abstract: Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks associated with a plurality of hybrid automatic repeat request (HARQ) processes. The UE may transmit an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE may transmit a feedback history report for a set of HARQ processes less than all of the plurality of HARQ processes.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may separately encode lower priority uplink control information (UCI) and higher priority UCI, and multiplex the encoded lower priority UCI and the encoded higher priority UCI on the same physical uplink channel (e.g., a physical uplink control channel (PUCCH)). The UE may be configured with multiple coding rates, which the UE may select from based on a payload size associated with each of the lower priority UCI and the higher priority UCI. Alternatively, the UE may be configured with a separate set of coding rates for the lower priority UCI and a separate set of coding rates for the higher priority UCI. The UE may multiplex the lower priority UCI and the higher priority UCI by mapping to physical uplink channel resources based on an order (e.g., mapping higher priority UCI followed by mapping lower priority UCI).

Abstract: A method of wireless communication includes determining, by a user equipment (UE), that one or more symbols scheduled for reporting a hybrid automatic repeat request (HARQ) acknowledgement (HARQ-ACK) to a base station for a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmission include at least one invalid symbol, wherein the one or more symbols are located in a first slot or sub-slot; selecting, by the UE, based on one or more parameters of the SPS PDSCH transmission, a second slot or sub-slot, subsequent to the first slot or sub-slot, for sending a delayed HARQ-ACK for the SPS PDSCH transmission; and sending, by the UE to the base station, the delayed HARQ-ACK for the SPS PDSCH transmission on the second slot or sub-slot.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink component carrier based at least in part on the communication received from the second UE, wherein the sidelink component carrier is associated with conveying the sidelink HARQ-ACK feedback when sidelink carrier aggregation is configured for a group of UEs that includes the first UE and the second UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, multiple code blocks (CBs) of a transport block. The first device may identify a CB bundle of one or more contiguous CBs that include one or more CBs for which negative feedback is to be reported. The first device may transmit, to the second device, an indication of the CB bundle. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a first physical downlink control channel (PDCCH) from a first transmission reception point (TRP) and a second PDCCH from a second TRP, wherein the first PDCCH and the second PDCCH include the same downlink control information (DCI), selecting a physical uplink control channel (PUCCH) resource for transmitting hybrid automatic repeated request acknowledgment (HARQ-ACK) feedback based on one of the first PDCCH or the second PDCCH, and transmitting a PUCCH that includes the HARQ-ACK feedback using the selected PUCCH resource.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may identify a configuration for discontinuous reception (DRX) for direct link communications with a second UE. The first UE may determine a channel busy ratio (CBR) based on a plurality of CBR measurement occasions within a time window prior to a direct link transmission based on the configuration for DRX. The first UE may determine whether to perform a congestion control on the direct link transmission based on the CBR. The first UE may perform a direct link transmission subject to a channel occupancy ratio limit.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a channel state reporting configuration for one or more semi-persistent scheduling (SPS) configurations for communications with a base station. For example, different channel state report configurations may be configured for the UE within the SPS configuration. Additionally, a downlink control information (DCI) associated with the SPS configuration may be used to activate the channel state report configuration. In some cases, different channel state report configurations may be configured for an SPS configuration, and the DCI may include a bit field to indicate which configured channel state report configuration is activated for the SPS configuration. Additionally, if the DCI indicates a release for an SPS configuration, the UE may refrain from transmitting channel state reports with an acknowledgment feedback acknowledging the release.
