Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Wireless communications devices and methods are adapted to facilitate DMRS sequence grouping. In one example, information is obtained for a transmission scheduled with pi/2 BPSK modulation, the transmission including two or more symbols scheduled for a DMRS (DMRS symbols). Respective DMRS sequences may be identified for each of the DMRS symbols, where each DMRS sequence subsequent to another DMRS sequence is dependent on its immediately preceding DMRS sequence, and the transmission may be sent with the identified DMRS sequences in the two or more DMRS symbols. In one example, a first transmission may be sent to schedule a second transmission from another device with pi/2 BPSK modulation, where the second transmission includes two or more DMRS symbols. The scheduled second transmission may be received with at least one DMRS symbol including a DMRS sequence based on its immediately preceding DMRS sequence. Other aspects, embodiments, and features are also included.

Abstract: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.

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 that support joint allocation for both an uplink message and a downlink message. In some cases, joint downlink control information (DCI) may indicate a time domain resource allocation (TDRA) for a downlink data channel and an uplink data channel. For example, bits of the joint DCI may be configured to indicate TDRA parameters of a downlink data channel (e.g., starting symbol, length value, slot offset, mapping type, timing advance, number of repetitions) and based on the TDRA parameters of the downlink data channel, TDRA parameters for an uplink data channel may be determined by a user equipment (UE) using the joint DCI.

Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may provide signaling with respect to one or more PAPR shaping resources. For example, a wireless device may provide signaling of PAPR shaping capability information. PAPR shaping capability information may include information regarding one or more PAPR shaping resources the wireless device has a capability to implement. Additionally or alternatively, a wireless device may provide signaling of PAPR shaping information. PAPR shaping information may include information regarding shaping the signal by a wireless device prior to transmission in a communication link by implementing one or more PAPR shaping resources. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive scheduling information for transmitting uplink control information in a first resource, where the first resource spans at least portions of a set of transmission time intervals. The UE may receive downlink data to be acknowledged via a feedback message in a second resource, where the second resource is within one of the set of transmission time intervals. The UE may identify that the first resource overlaps in time with the second resource. The UE may determine a transmission resource for the feedback message based on the first resource overlapping the second resource, the first resource spanning at least portions of the set of transmission time intervals, and the second resource being within one of the set of transmission time intervals. The UE may transmit feedback message via the transmission resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to report first channel state information (CSI), wherein the first CSI is associated with a parameter that indicates a priority of the first CSI. The UE may prioritize the first CSI over a second CSI based at least in part on the parameter. The UE may transmit an indication of the first CSI and may drop the second CSI based at least in part on prioritizing the first CSI over the second CSI. Numerous other aspects are provided.
