Abstract: Methods, systems, and devices for wireless communication at a first user equipment (UE) are described. A UE may receive a control signal indicating a set of durations. A duration of the set of durations may be scheduled for uplink resources and additional resources including downlink resources, flexible resources, or both. The UE may further receive an indication of a slot format configuration permitting sidelink communications on the uplink resources during the duration scheduled for the uplink resources and the additional resources. Upon identifying that sidelink communications are permitted, the UE may transmit a sidelink transmission using the uplink resources and during the duration.

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. A communications device may receive a downlink control message that supports indicating multiple modes for reporting hybrid automatic repeat request feedback, including a first mode for reporting hybrid automatic repeat request feedback and channel information according to a bundled configuration and a second mode for reporting hybrid automatic repeat request feedback according to a standalone configuration. The communications device may use the downlink control message to determine a mode for transmitting hybrid automatic repeat request feedback. The communications device may also transmit either bundled hybrid automatic repeat request feedback and channel information or standalone hybrid automatic repeat request according to the determined mode.

Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a user equipment (UE)) may receive signaling indicating a set of channel state information (CSI) report configurations for sidelink communications between the first device and a second device. The first device may then receive a request from the second device for a CSI report according to a first CSI report configuration from the set of CSI report configurations. The first device may perform channel measurements based on receiving the request and may generate the CSI report using the channel measurements according to the first CSI configuration. In some cases, the first device may determine whether to additionally generate the CSI report using one or more previous channel measurements based on whether the previous channel measurements were taken according to the same CSI report. The first device may then transmit the generated CSI report to the second device.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a request for beamforming information associated with line-of-sight (LoS) multiple input multiple output (MIMO) communication from a second wireless device. The first wireless device may generate a channel estimation matrix for a channel between rectangular antenna arrays of the respective wireless devices, the channel estimation matrix including one or more quadratic terms for the LoS MIMO communication. The first wireless device may generate a first sub-matrix and a second sub-matrix based on the channel estimation matrix. The first wireless device may transmit an indication of a set of precoders for the LoS MIMO communication, the set of precoders based on a symmetry associated with the first and second sub-matrices, and may receive the LoS MIMO communication from the second wireless device based on the set of precoders.

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. According to one or more aspects, a device, such as a user equipment (UE), may receive, from one or more base stations during a first time unit, a control signal including an indication of a reference signal bundling configuration associated with one or more physical channel types which may be potentially scheduled during a set of time units after the first time unit. The UE may determine the set of time units based on the indication of the reference signal bundling configuration. Additionally or alternatively, the UE may receive scheduling configuration of one or more physical channels, and the one or more physical channels during one or more second time units of the set of time units. The UE may then bundle the one or more physical channels based on the reference signal bundling configuration.
