Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select a precoding matrix of orthogonal beams. The base station may precode a channel state information reference signal (CSI-RS) transmitted to a user equipment (UE) using the precoding matrix of orthogonal beams. The base station may receive, from the UE, one or more reports that indicate one or more beam indices selected from beam indices associated with the precoding matrix of orthogonal beams. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for dynamically configuring connected discontinuous reception (C-DRX) configurations supporting network power modes are described. In some examples, a user equipment (UE) may receive a first control signaling configuring the UE with multiple C-DRX configurations, each C-DRX configuration of the multiple C-DRX configurations corresponding to a respective network power mode. In some examples, the UE may receive a second control signaling including an identifier indicating a C-DRX configuration, of the multiple C-DRX configurations, corresponding to a first network power mode (e.g., an enhanced network power savings mode) at a base station, where the first network power mode may indicated a set of features active at the base station. The UE may communicate with the base station in accordance with the indicated C-DRX configuration and based on the first network power mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may generate a set of orthogonal sequences that the UE may use to convey a payload of a number of bits based on a product of an orthogonal matrix and a cell-specific sequence. The UE or the base station, or both, may select a subset of the set of orthogonal sequences based on the number of bits in the payload, and the UE may construct a codebook including the subset of orthogonal sequences. The UE may select an orthogonal sequence from the constructed codebook based on the bits in the payload. The UE may transmit the payload including the number of bits to the base station using the selected orthogonal sequence.

Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: In a positioning session for a user equipment (UE), one or more base stations may receive and derive positioning measurements from uplink (UL) transmission from the UE that include a physical resource block (PRB) interlaced waveform based on at least one of interlaced physical uplink control channel (PUCCH) resource blocks, interlaced physical uplink shared channel (PUSCH) RBs resource blocks, interlaced sounding reference signal (SRS), interlaced uplink (UL) positioning reference signal (PRS), or a combination thereof. The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements. The base station may report the positioning measurements along with the channel used and enhanced accuracy requirements to a location server for positioning.

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 base station may transmit signaling to a user equipment (UE) indicating one or more resources for a relay data transmission and a priority scheme for the relay data transmission and a current data transmission. The priority scheme may indicate a priority value for the relay data transmission and the current data transmission. The UE may selectively transmit the relay data transmission, the current data transmission, or both based on the priority scheme. If the priority scheme indicates the current data transmission has a higher priority than the relay data transmission, then the UE may transmit the current data transmission using the resources. If the priority scheme indicates the current data transmission has a lower priority than the relay data transmission, then the UE may transmit the relay data transmission using the resources.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may configure a relay configuration for a set of user equipments (UEs). The relay configuration may include a set of first direction transmission opportunities and corresponding second direction transmission opportunities. The relay configuration may be activated or deactivated, such as on a packet-by-packet basis. When the relay configuration is activated, a first UE and one or more second UEs may sequentially transmit a packet using the first direction transmission opportunities so as to be receivable by the wireless device and each other. The relay process may continue, for example, until the wireless device successfully receives the packet. The wireless device may monitor the first direction transmission opportunities and transmit positive or negative acknowledgments during the second direction transmission opportunities to indicate whether it has successfully received the packet.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. An example method of wireless communication at a user equipment includes receiving a data transmission for each of a plurality of component carriers (CCs) over a wireless channel from a base station, wherein each data transmission is associated with a number of code block groups (CBGs). The method further includes identifying a feedback protocol to apply to the plurality of CCs and selecting a subset of the plurality of CCs for which to report feedback information for the CBGs based at least in part on the feedback protocol. The method may also include generating the feedback information based at least in part on the subset of the plurality of CCs and the feedback protocol and transmitting a feedback message that indicates the feedback information for the subset of the plurality of CCs of the wireless channel to the base station.
