Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to bundle or not bundle demodulation reference signals (DMRS) of multiple downlink data transmissions using an indication from a base station. The indication may be transmitted via control signaling, such as downlink control information (DCI) from the base station to the UE. For example, a bit of the DCI may be used to dynamically indicate a current precoding in relation to a preceding precoding. For example, the bit may indicate if the current precoding is the same as a previous precoding (e.g., UE may bundle the DMRS), or the bit may indicate that the current precoding is different than the previous precoding (e.g., UE may not bundle DMRS).

Abstract: Disclosed are techniques for reducing overhead of low layer positioning reports. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode determines that the UE is not expected to wake up during a next DRX ON duration of a DRX cycle; determines, based on one or more factors, whether to wake up during the next DRX ON duration to transmit a positioning measurement report or an uplink positioning reference signal (UL-PRS); and based on the determination: wakes up and transmits the positioning measurement report or the UL-PRS during the next DRX ON duration, or remains in a DRX sleep state and refrains from transmitting the positioning measurement report or the UL-PRS during the next DRX ON duration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information that schedules a physical downlink shared channel (PDSCH) communication for the UE; and select a downlink beam for reception of the PDSCH communication from a set of usable downlink beams associated with an uplink beam to be used by the UE for uplink transmission in one or more symbols in which the PDSCH communication is scheduled. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engages in a downlink positioning session, a sidelink positioning session, or both with one or more first network entities, and transmits at least one positioning capability report to one or more second network entities, the at least one positioning capability report including one or more parameters indicating joint downlink and sidelink capabilities of the UE to process both downlink positioning reference signals (DL-PRS) and sidelink positioning reference signals (SL-PRS).

Abstract: A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.

Abstract: Disclosed are techniques related to wireless communication. In an aspect, a sequence generating entity factorizes a comb size N into prime factors of N, and generates one or more offset sequences for a reference signal for positioning based on one or more sequence lists associated with the prime factors of N and a number of symbols M over which the reference signal is scheduled.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently reporting channel state feedback for a set of subbands. As an example, a user equipment (UE) may receive a set of reference signals on the set of subbands and determine a respective channel quality indicator (CQI) index for each of the set of subbands based on the reference signals. The UE may then transmit indications of CQI indices for different subbands of the set using variable length indications, such as indications that include different numbers of bits. Since, in some examples, a small length or number of bits may be allocated for reporting CQI indices with a high probability of being reported, overhead in a wireless communications system may be reduced.

Abstract: A user equipment (UE) receives a maximum downlink (DL) Multiple-Input Multiple-Output (MIMO) layer configuration for DL communications, such as control signals or data signals, in one or more bandwidth parts (BWPs) and a positioning reference signal (PRS) configuration for receiving DL PRS. The UE receives DL PRS in an active BWP using a number of reception antennas based on, e.g., at least equal to, the maximum number of DL MIMO layers in the active bandwidth part. The UE may be configured to transmit uplink (UL) PRS, e.g., SRS for positioning purposes, using at least a maximum number of transmission antennas that is configured for communications purposes.
