Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving control messages that schedule a first and second set of repetitions of an uplink transmission to respective transmission/reception points (TRPs). The one or more control messages may be indicative of a first redundancy version (RV) sequence that is to be applied to the first set of repetitions and a second RV sequence that is to be applied to the second set of repetitions. The control messages may also indicate a first set of power control parameters and a second set of power control parameters. The UE may map the first and second set of power control parameters to the first and second set of repetitions according to a rule. The UE may transmit the first and second sets of repetitions according to the respective RV sequences and power control parameters.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications in order to minimize the number of subchannels that a receiver (e.g., PLC or SA) may need to blind decode. More particularly, the search space is configurable based on a hashing function that is based in part on a portion of the resources (e.g., PLC resources) that have been allocated or reserved for sidelink communication within the PLC subnetwork (or PLC group) from the sidelink resource pool available to a plurality of PLCs in a network. By limiting the search space to a subset of resources that are specific to the PLC subnetwork or group, the need for the SA or PLC to perform blind decoding of sidelink control information (SCI) may be further reduced.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink channel access via a floating channel occupancy. In some aspects, a cellular device may operate within a proximity of one or more wireless fidelity (Wi-Fi) devices and may conditionally support a search space associated with a floating sidelink synchronization signal block (SSB). For example, if the cellular device detects that the Wi-Fi devices are precluding the cellular device from acquiring channel access or otherwise making it relatively more difficult for the cellular device to acquire channel access, the cellular device may enable or active a use of the search space associated with the floating sidelink SSB. If enabled or activated, the cellular device may transmit a floating sidelink SSB within the search space independent of slot boundaries upon a successful listen-before-talk (LBT) procedure.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may measure a frequency selectivity of a channel between the UE and a base station and may transmit signaling to the base station indicating one or both of a frequency selectivity metric or a recommended demodulation reference signal (DMRS) port multiplexing pattern based on measuring the frequency selectivity. In some aspects, the UE may transmit the signaling to assist the base station in configuring a DMRS port multiplexing pattern based on current channel conditions. For example, if the frequency selectivity metric satisfies a threshold, the UE may recommend a DMRS port multiplexing pattern absent of code division multiplexing (CDM). Alternatively, if the frequency selectivity metric fails to satisfy the threshold, the UE may recommend a DMRS port multiplexing patter including CDM.

A user equipment (UE) performs a first channel access procedure for accessing a channel occupancy time (COT) within the sidelink channel. The UE transmits a second-stage sidelink control information (SCI) message (SCI-2) including COT sharing information (COT-SI) for sharing the COT with other devices, and transmits a first sidelink message within a first portion of the COT. The UE identifies a second sidelink message that is expected to be received within a second portion of the COT, and performs a second channel access procedure for accessing the COT after identifying the second sidelink message based on the second sidelink message being expected within a set of resources reserved for the second sidelink message. Subsequently, the UE transmits a third sidelink message within a third portion of the COT based on a completion of the second channel access procedure.

Frequency resources for the PTRSs may change across the different transmissions based on the PTRS hopping offset.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining sidelink channel metrics using reference signal measurements of reference signals transmitted by other UEs. A first UE may receive a control message from a base station, and the control message may indicate a measurement threshold. The first UE may generate a reference signal measurement of a reference signal transmitted by a second UE via a sidelink channel between the first UE and the second UE. The UE may transmit a measurement report to the base station based at least in part on the measurement satisfying the threshold. The report may be a quantized value of the measurement or a bit indicating that the measurement satisfies the threshold. Based on receipt of the measurement report, the base station may determine to transmit data to the second UE via a transmission to the first UE.
