Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols. The UE may determine a power level for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols indicated by the configuration. The UE may transmit, to a base station, the repetition on the using the power level.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently scheduling semi-persistent scheduling (SPS) downlink transmissions and dynamic downlink transmissions to maximize throughput in a wireless communications system. In one example, a user equipment (UE) may receive downlink data in a dynamic downlink transmission and receive the same downlink data or no data in an SPS downlink transmission when the dynamic downlink transmission is scheduled to occur after the SPS downlink transmission and before an uplink feedback transmission for the SPS downlink transmission. In another example, a UE may receive downlink data in a dynamic downlink transmission and receive the same downlink data or no downlink data in an SPS downlink transmission when the SPS downlink transmission is scheduled to occur after the dynamic downlink transmission and before an uplink feedback transmission for the dynamic downlink transmission.

Abstract: A design is provided for spatially multiplexing uplink channels. A user equipment (UE) detects that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously. The UE decides to spatially multiplex the PUCCH and the SRS for simultaneous transmission via different sets of one or more antennas. The UE determines time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS. The UE transmits the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.

Abstract: Methods, systems, and devices for wireless communications provide for feedback transmissions using an uplink shared channel. A user equipment (UE) may transmit feedback to a base station using physical uplink shared channel (PUSCH) resources. The base station may transmit an uplink grant to the UE indicating a set of resources for uplink data transmissions. The base station may subsequently transmit a downlink grant for the UE. Based on monitoring resources indicated by the downlink grant, the UE may generate feedback indicating the success of receiving or decoding the PDSCH transmission. The UE may transmit the feedback to the base station on the PUSCH resources. In some cases, the UE may transmit both the feedback for the PDSCH transmission received after the uplink grant and for a second PDSCH transmission received prior to the uplink grant using PUSCH resources.

Abstract: Wireless communications systems and methods related to managing sidelink interference on resources shared with a direct link in a wireless communication network are provided. A first user equipment (UE) receives, from a base station (BS), a configuration indicating one or more sidelink interference measurement resources for determining an interference from a sidelink to a direct link of the BS. The first UE communicates, with a second UE, a reference signal in at least a first sidelink interference measurement resource of the one or more sidelink interference measurement resources, where one of the first UE or the second UE is associated with the sidelink, and where the other one of the first UE or the second UE is associated with the direct link.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may determine a configuration for partitioning a set of sequences into multiple sequence pools associated with multiple UEs. The UE or the base station, or both, may determine a sequence pool associated with the UE based on the configuration, which may include parameters or instructions for determining the sequence pool associated with the UE. The UE or the base station, or both, may select a subset of sequences from the sequence pool associated with the UE and construct a codebook including the subset of sequences. The UE may select a sequence from the constructed codebook based on a quantity of bits of a payload and may transmit the payload to the base station using the selected sequence.
