Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select an uplink transmission power sharing configuration to use for transmission of one or more uplink messages. The uplink transmission power sharing configuration may be based on a first uplink transmission power capability of a first radio frequency (RF) chain of the UE and on a second uplink transmission power capability of a second RF chain of the UE. The UE may transmit the one or more uplink messages to a network entity in accordance with the uplink transmission power sharing configuration. Specifically, the UE may transmit the one or more uplink messages via the first RF chain using a first transmission power, and may transmit the one or more uplink messages via the second RF chain using a second transmission power that is different from the first transmission power.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives signaling configuring the UE with a control resource set (CORESET) activated with two transmission configuration indicator (TCI) states. The UE further receives a downlink control information (DCI) triggering transmission of aperiodic channel state information (CSI) reference signals (RSs) on aperiodic CSI-RS resources. The UE applies a quasi-colocation (QCL) assumption of at least one of the two TCI states for processing the aperiodic CSI-RSs, when a scheduling time offset is less than a threshold value and depending on whether same or different aperiodic CSI-RS resources are received from two transmission reception points (TRPs) associated.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, the method may include a user equipment (UE) transmitting, to a base station, first reference signals. The base station may perform channel estimation using the first reference signals and estimate a value for an uplink channel based on the channel estimation. The base station may generate second reference signals such that a characteristic of a downlink channel seen by the UE is within a target value and transmit the second reference signals to the UE. The UE may estimate a value for the characteristic of the downlink channel and obtain the target value from the estimated value. Both the UE and the base station may generate a secret using the target value and utilize the secret key for physical layer protection.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive control signaling indicating a first semi-static configuration for transmitting uplink signaling and a second semi-static configuration for receiving downlink signaling. In some cases, the UE may operate using half-duplex communications and may monitor for a transmission direction conflict between the first semi-static configuration and the second semi-static configuration during a transmission time interval. The UE may communicate, according to a priority rule, one of an uplink signal in accordance with the first semi-static configuration or a downlink signal in accordance with the second semi-static configuration during the transmission time interval based on the monitoring. Additionally, or alternatively, the UE may drop one of the uplink signal or downlink signal according to the priority rule.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a first signal from a second wireless device and may identify a first bundle size for a precoding resource group (PRG) based on a characteristic of the first signal and, in some examples, based on performing channel estimation on the first signal. The first wireless device may transmit a feedback message to the second wireless device indicating a second bundle size for the PRG and associated with a second signal based on identifying the first bundle size. In some examples, the first wireless device may receive the second signal on a set of resources in accordance with the second bundle size. The first signal may be an example of a channel state information reference signal (CSI-RS), and the second signal may be an example of a precoded CSI-RS or a demodulation reference signal (DMRS).

Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, DCI associated with SPS. The apparatus may also identify whether the DCI is EH SPS activation DCI, EH SPS reactivation DCI, data SPS activation DCI, data SPS reactivation DCI, or SPS release DCI, the EH SPS activation DCI and the EH SPS reactivation DCI corresponding to an EH configuration, the data SPS activation DCI and the data SPS reactivation DCI corresponding to a data processing configuration. Additionally, the apparatus may configure an EH component associated with the EH configuration if the DCI is the EH SPS activation DCI or the EH SPS reactivation DCI, or performing data processing associated with the data processing configuration if the DCI is the data SPS activation DCI or the data SPS reactivation DCI.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a victim network entity to share a downlink preemption pattern with user equipments (UEs) and neighboring network entities. For example, the victim network entity may transmit, to a UE and/or a neighbor network entity, control signaling indicating a recurring downlink preemption pattern defining one or more resources during which the UE may preempt reception of downlink signaling and the victim and neighbor network entities may preempt transmission of downlink signaling. The UE and the network entities may refrain from monitoring for downlink transmissions and transmitting downlink transmissions, respectively, in accordance with the indicated downlink preemption pattern. In some examples, the UE and the network entities may be configured with one or more conditions for discarding the indicated downlink preemption pattern and monitoring the one or more resources for or transmitting downlink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.
