Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.

Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a first network node measures one or more first reference signals on a first carrier frequency, the one or more first reference signals received from a second network node to enable determination of one or more first characteristics associated with one or more target objects, and measures one or more second reference signals on a second carrier frequency, the one or more second reference signals received from the second network node to enable determination of one or more second characteristics associated with the one or more target objects, wherein an accuracy of the one or more second characteristics is higher than an accuracy of the one or more first characteristics based on the one or more first reference signals being measured on the first carrier frequency and the one or more second reference signals being measured on the second carrier frequency.

In one aspect, a user equipment (UE) can receive a CSI-RS resource including a first CSI-RS port on a first beam from a first cell of a network entity, the CSI-RS resource including a second CSI-RS port of the second cell on a second beam from a second cell of the network entity. In another aspect, a network entity can transmit, on a first beam from a first cell to a UE, a CSI-RS resource including a first CSI-RS port of the first cell, and transmit, on a second beam from a second cell to the UE, the CSI-RS resource including a second CSI-RS port of the second cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may map a code block to resources, of a physical shared channel, that are allocated for data-modulated demodulation reference signals (DMRSs) in which each of the resources carries both at least a portion of a DMRS sequence and data. The wireless communication device may transmit a communication, via the physical shared channel, that includes the code block that is mapped to the resources that are allocated for the data-modulated DMRSs. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to configuring the structures of synchronization signal blocks (SSBs) and SSB burst sets in scenarios where two or more different types of SSB burst sets may be utilized in a wireless communication system (e.g., SSB burst sets including SSBs having different subcarrier spacing (SCS)). The SSB burst sets may be configured to include different components in an SSB (e.g., one or more of primary and second synchronization signals and a physical broadcast channel), include resource allocation information, include a physical-layer cell identity (PCID) configuration for a first SSB burst set that may be used to determine a PCID for a second SSB burst set, and enable quasi co-locating SSBs in a first SSB burst set with a second SSB burst set.
