Abstract: Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.

Abstract: Methods, systems, and devices for wireless communications are described that support non-periodic channel state information (CSI) triggering and reporting in wireless communications. In cases where two or more CSI report requests trigger multiple CSI report transmissions in an same uplink slot, a user equipment (UE) may format at least a subset of the multiple CSI reports according to a formatting configuration for transmission of multiple CSI reports in a same uplink slot. The UE may use allocated resources in the uplink slot for each CSI report that are allocated by the base station in the corresponding CSI report request. In some cases, the UE may combine the multiple CSI reports, or parts thereof, into a combined CSI report that may be transmitted using allocated resources of one of the CSI report requests.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor a downlink transmission for control information during a set of physical downlink control channel (PDCCH) monitoring occasions. The UE may determine a first configuration for the set of PDCCH monitoring occasions during a slot of the downlink transmission and a threshold number of PDCCH candidates and/or a threshold number of non-overlapping CCEs within the slot. In some cases, the UE may also determine a threshold number of PDCCH candidates and/or non-overlapping control channel elements (CCEs) within a single PDCCH monitoring occasion. The threshold number of PDCCH candidates and non-overlapping CCEs may be fixed, based on the number of PDCCH monitoring occasions during the slot, based on a processing capability of the UE, or a combination thereof. The UE may decode control information contained in one or more of the PDCCH monitoring occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate, with a second UE, information indicating a direct current (DC) location for a communication link between the first UE and the second UE. The UE may communicate a sidelink communication with the second UE via the communication link based at least in part on the DC location. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split the uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.

A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for configuring sounding reference signal (SRS) transmissions on subband full-duplex (SBFD) slots. In an example, a user equipment (UE) may determine a change from a first uplink (UL) bandwidth pattern to a second UL bandwidth pattern occurred within in a sub-band full duplex (SBFD) bandwidth. The UE may also configure one or more settings for a sounding resource signal (SRS) transmission based on the second UL bandwidth pattern. The UE may also transmit, to a base station, the SRS transmission according to the one or more settings for the SRS transmission.

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 downlink control information, and may determine assignment information for processing batch-based feedback based on the downlink control information. The UE may determine the batch-based feedback for a batch of downlink transmissions (for example, transmissions associated with packets of information) that are configured to be processed together by the UE. The UE may receive a downlink transmission from the base station, and may construct a codebook based on assignment information and the downlink transmission. In some examples, the UE may determine acknowledgment feedback for the downlink transmission based on the codebook. The UE may transmit the acknowledgment feedback to the base station.

Abstract: Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.
