Abstract: Aspects relate to wireless communication including the provision of the ability of a user equipment (UE) to indicate the capability of the UE for demodulation reference signal (DMRS) bundling and/or joint channel estimation (JCE). In aspects, the capability indication includes using at least a physical random access channel (PRACH) to indicate the capability of a UE for repeated transmission of the physical uplink shared channel (PUSCH) carrying a connection message, and counting of available slots that are used for the repeated transmission of the physical channel. Additionally, the UE may be configured to indicate the capability for JCE through a demodulation reference signal (DMRS) configuration or a DMRS port.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message from a base station indicating a configuration of an uplink waveform for full-duplex communications at the UE. The UE may receive an additional control message scheduling a set of uplink resources and a set of downlink resources for the full-duplex communications. The set of uplink resources and the set of downlink resources may at least partially overlap in a time-domain. A frequency-domain gap between the set of uplink resources and the set of downlink resources may be based on the first uplink waveform and a first downlink waveform used by the base station. The UE may communicate with the base station on the set of uplink resources and the set of downlink resources in accordance with the frequency-domain gap.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation parameter for a Physical Uplink Shared Channel (PUSCH) transmission in a random access procedure, determine a repetition level for the PUSCH transmission based on the aggregation parameter, and transmit, as part of the random access procedure, the PUSCH transmission according to the repetition level. A base station may determine a repetition level for a Physical Uplink Shared Channel (PUSCH) transmission in a random access procedure, transmit, to a user equipment (UE), an aggregation parameter indicating the repetition level, and receive, as part of the random access procedure, the PUSCH transmission according to the repetition level.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink shared channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink shared channel transmission. Each frequency hop may be determined based on a corresponding uplink shared channel index for a respective repetition a frequency hop for each repetition of the uplink shared channel transmission. The uplink shared channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink shared channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Aspects are provided which allow a first wireless device such as a UE or base station to prioritize beams which are simultaneously received from or transmitted to cells of different numerologies or which are asynchronous to each other. The device determines an overlap in time between a first signal from a first cell and a second signal from a second cell, where the second cell includes at least one of a different numerology than the first cell or an asynchronous timing relative to the first cell. The device applies a beam prioritization rule for selecting a beam associated with the first signal or the second signal carrying information in separate beams. The device transmits information to or receives information from a second wireless device based on the selected beam. Thus, simultaneous beam conflict resolution may be improved for cells having different numerologies or asynchronous timing.

Abstract: A first user equipment (UE) for wireless communication may be configured to send, to a second UE, a plurality of sidelink reference signals (SL-RSs), wherein the first UE and the second UE are configurable to communicate with a network entity, and wherein the plurality of SL-RSs includes a first SL-RS corresponding to a first operational state of the network entity. The first UE may receive, from the second UE, one or more channel state information (CSI) reports, wherein each CSI report of the one or more CSI reports corresponds to a respective SL-RS of the plurality of SL-RSs.
