Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: Certain aspects of the present disclosure provide techniques for relaying physical sidelink control channel in sidelink communications. A method that may be performed by a first user equipment (UE) includes receiving a sidelink control information (SCI) transmission from a second UE, the SCI pointing to one or more resources for a retransmission of the SCI by the second UE. The method may include transmitting the SCI to a third UE using the one or more resources for the retransmission of the SCI by the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for dynamically adapting a baseband resource envelope (e.g., baseband resources) allocated to a network entity. A virtual radio access network (VRAN) manager (e.g., a host platform for a VRAN) may perform baseband pooling to allocate a baseband resource envelope to a network entity for signal processing at the network entity. The network entity may perform measurements indicating the channel conditions associated with communicating with one or more user equipment (UEs), and the network entity may report the measurements to the VRAN manager. The VRAN manager may then adapt a baseband resource envelope allocated to the network entity based on the measurements to improve the utilization of processing resources.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink (SL) channel selection coordination. A method that may be performed by a user equipment (UE) includes measuring, during a time period shorter than one slot, a channel condition of at least one first channel in a sidelink (SL) frequency band. The method further includes transmitting a signal on the at least one first channel or a second channel of the SL frequency band, wherein the at least one first channel or the second channel is chosen based on the channel condition.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes communicating control signaling scheduling a sidelink transmission via a physical sidelink channel, receiving, by a first user equipment (UE), the sidelink transmission including one or more reference signals from a second UE via the physical sidelink channel based on the control signaling, and monitoring the physical sidelink channel based on time synchronization, frequency synchronization, or both, determined using the one or more reference signals.

Abstract: Methods, systems, and devices for dynamic physical downlink shared channel (PDSCH) mapping modes are described. In some examples, a user equipment (UE) may receive a first control message identifying one or more sets of resources around which the UE may rate match for a downlink channel. In some examples, the UE may receive a second control message including an indication that the UE may perform either rate matching around at least one set of resources of the one or more sets of resources or receiving the downlink channel on the at least one set of resources. As such, the UE may receive signals on the downlink channel according to the indication received in the second control message.

Abstract: Methods, systems, and devices for wireless communications are described. One or more UEs communicating over sidelink may indicate transmit and receive categories to other UEs. A first UE may receive, in a sidelink communication message, an indication of a receive category of a second wireless device. The first UE may then transmit a shared sidelink channel message to the second wireless device based on the receive category of the second wireless device. In another case, a first UE may receive, in a sidelink communication message, an indication of a transmit category of a second wireless device. The first wireless device may then compare the transmit category of the second wireless device with a receive category of the first wireless device. The first wireless device may determine whether to decode a shared sidelink channel message from the second UE based on the comparing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.
