Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a shared radio frequency spectrum band for a transmission opportunity. The UE may perform an autonomous uplink transmission over the shared radio frequency spectrum band during a first portion of the transmission opportunity. The UE may transmit a physical layer scheduling request comprising a transmission size parameter for a second portion of the transmission opportunity. The UE may receive an uplink grant for the second portion of the transmission opportunity based at least in part on the scheduling request. The UE may perform a scheduled uplink transmission over the shared radio frequency spectrum band during the second portion of the transmission opportunity according to the uplink grant.

Abstract: Subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the occurrence or presence of a synchronization signal block (SSB) transmission. For example, during a SSB transmission, the SCS of data may be automatically switched from some default data SCS to a second SCS (e.g., the SCS of the SSB) to allow for frequency division multiplexing (FDM) of data and SSB where the data and SSB use the same numerology. As such, communicating devices (e.g., a base station and a user equipment (UE)) may identify some location or configuration for a SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) such that the SCS of data may be adapted to the second subcarrier spacing during the FDM of the SSB and the data. The SSB and data may thus be contemporaneously transmitted or received using the second SCS.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node receives a reference signal comprising a plurality of time and frequency resources, the plurality of time and frequency resources spanning a plurality of disjoint bandwidth segments, the plurality of disjoint bandwidth segments being time aligned or having a known time offset with respect to each other, and determines a time of arrival (ToA) of the reference signal based on jointly processing the plurality of time and frequency resources of the reference signal across the plurality of disjoint bandwidth segments.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, a downlink transmission in a radio frequency spectrum band and may identify reference resources in the downlink transmission for computing a channel state information (CSI) report. The UE may generate the CSI report based at least in part on the identified reference resources and transmit, in the radio frequency spectrum band, the CSI report in a random access request message to the base station. The base station may receive the request message and identify CSI associated with the band based at least in part on the CSI report included in the random access request message. The base station may transmit, to the UE, a random access response message based at least in part on the identified CSI in the radio frequency spectrum band.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may transmit a message to a base station (e.g., a NodeB, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB)) in wireless communications with the UE. The message may include a UE capability to append a preamble waveform to an uplink transmission to the base station. In some examples, a preamble waveform may include a Wi-Fi preamble or a new radio unlicensed (NR-U) preamble. Based on the UE capability, the base station may determine and transmit a preamble configuration to the UE, which the UE may use to generate and append a preamble waveform to another message for an uplink transmission to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently identifying a receive beam for performing a listen before talk (LBT) procedure in an attempt to gain access to a transmission opportunity (TxOP) in a shared radio frequency spectrum. In particular, a wireless device may select a receive beam that corresponds to one or more transmit beams to be used in a TxOP to perform an LBT procedure in an attempt to gain access to the TxOP. In one example, the wireless device may select a receive beam for performing an LBT procedure based on the energy of each of the transmit beams to be used in a TxOP. In another example, the wireless device may select a receive beam for performing an LBT procedure if the receive beam is quasi co-located with each of the transmit beams to be used in a TxOP.
