Abstract: Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a user equipment (UE) receives, from a network node, multiple resource sets for tracking (TRSs). Each TRS comprises a plurality of reference signal resources. The multiple TRSs are signals from a same antenna port or are quasi-co-located signals. The UE processes the multiple TRSs to determine positioning-related quantity(ies). The UE can estimate its position based on the positioning-related quantity(ies) and/or send the positioning-related quantity(ies) to the network.

Abstract: Aspects of the disclosure relate to determining a transmission configuration indication (TCI) state for receiving a multi-transmission point (TRP) communication. A receiving device receives a configuration message indicating a lowest control resource set identifier (CORESET ID) for receiving one or more downlink control information (DCI) and determines whether a state of the receiving device is within a scheduling threshold duration for decoding DCI. The receiving device then determines a TCI state for receiving data based on a TCI state associated with the lowest CORESET ID if the state of the receiving device is within the scheduling threshold duration, wherein the TCI state associated with the lowest CORESET ID indicates one or more sets of quasi co-location (QCL) parameters. The receiving device then receives the data from one or more transmission points (TRPs) based on the one or more sets of QCL parameters.

Abstract: A method for wireless communications, comprising: signaling, to a user equipment (UE), an indication of one of at least two rules regarding how quasi co-location (QCL) configured for the UE should be applied for one or more DMRS ports; and sending downlink transmission to the UE with the one or more DMRS ports; receiving signaling from a base station and processing signals received on one or more DMRS ports based on the indicated rule. Said method improves communications between access points and stations in a wireless network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a capability indicator from a user equipment (UE) that indicates a capability of the UE to decode downlink control information (DCI) on a physical downlink shared channel (PDSCH). In some aspects, the base station may transmit, to the UE, the DCI on the PDSCH based at least in part on the capability indicator indicating that the UE can decode the DCI on the PDSCH. Numerous other aspects are provided.

Abstract: Disclosed are techniques for utilizing synchronization signal blocks for positioning operations. In an aspect, a transmission point configures a set of synchronization signal blocks to be used as positioning measurement signals, each of the plurality of synchronization signal blocks comprising a primary synchronization signal, a secondary synchronization signal, and one or more physical broadcast channel signals, and transmits the set of synchronization signal blocks on a wireless downlink channel to enable a user device to perform a positioning measurement of at least one of the set of synchronization signal blocks. In an aspect, the user device receives, from the transmission point, the plurality of synchronization signal blocks on the wireless downlink channel, receives, from the transmission point, an indication of the set of synchronization signal blocks to be used as positioning measurement signals, and performs a positioning measurement of at least one of the set of synchronization signal blocks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that multiple uplink channels are to be transmitted contemporaneously via different antennas on a component carrier. The user equipment may determine a respective transmit power for multiple uplink communications associated with the multiple uplink channels based at least in part on a set of priority rules that identifies a respective priority for the multiple uplink communications. The user equipment may transmit the multiple uplink communications using the respective transmit power. Numerous other aspects are provided.

Abstract: Wireless communication devices are adapted to facilitate multiplexing of signals. According to one example, a wireless communication device can multiplex a first signal and a second signal for transmission across a first resource element and a second resource element. The first resource element may utilize a first subcarrier in a first symbol employing a first numerology. The second resource element may utilize a second subcarrier in a second symbol employing a second numerology that is different from the first numerology, where the second subcarrier overlaps in frequency at least a portion of the first subcarrier. The first and second symbols including the multiplexed first and second signals may subsequently be transmitted. Other aspects, embodiments, and features are also included.

Abstract: The present disclosure provides techniques that may be applied, for example, for determining phase tracking reference signal (PT-RS) patterns/configurations. As described herein, PT-RS may be mapped to a symbol based, at least in part, on one or more symbols in which a PT-RS is expected to be punctured due to a collision with at least one of time or frequency resources allocated to another signal or to another wireless device, a MCS, and/or an expected PT-RS density.

Abstract: Aspects of the present disclosure provide a bandwidth-dependent maximum number of control symbols. As described herein, a BS may determine a channel bandwidth for communicating with a UE, determine a maximum number of downlink control symbols based, at least in part, on the determined channel bandwidth, and transmit up to the maximum number of downlink control symbols to the UE. According to aspects, a DMRS may be transmitted after the maximum number of downlink control symbols. For example, the DMRS may be transmitted in a symbol immediately following the downlink control symbols.
