Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information reference signal (CSI-RS) for multiple beam transmissions. In an example, a first CSI-RS triggering state of one or more CSI-RS triggering states indicates a CSI-RS resource set and associated transmission configuration indication (TCI) states. The CSI-RS resource set includes a plurality of CSI-RS resources. Each CSI-RS resource of the plurality of CSI-RS resources is associated with one or more corresponding TCI states as indicated by the first CSI-RS triggering state. A first CSI-RS resource of the plurality of CSI-RS resources is associated with a first plurality of TCI states as indicated by the first CSI-RS triggering state.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may perform a first transmission to one or more receiving devices, the first transmission associated with a transmission type. The transmitting device may determine a feedback response for the first transmission based on monitoring for feedback messages from the one or more receiving devices in response to the first transmission. The transmitting device may select a contention window size for performing one or more subsequent transmissions based at least in part on the feedback response and the transmission type. The transmitting device may perform the one or more subsequent transmissions in accordance with a clear channel assessment procedure using the selected contention window size.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, physical downlink control channel (PDCCH) candidates in first and second search space (SS) sets may be located in a same slot. When both SS sets have the same periodicity and the same offset, the UE may determine that SS sets are linked. The UE may expect the same number of monitoring occasions for each SS set within the slot, and may determine that a monitoring occasion in the first SS set having a first index value is linked with a monitoring occasion in the second SS set that has the same index value. The UE may determine that monitoring occasions for the different SS sets that have the same periodicity but different offsets are located in different slots, and that rules are satisfied such that a first PDCCH repetition is located in an earlier slot than the second PDDCH repetition.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive, from a second UE such as a PLC, sidelink control information scheduling a first transmission to be transmitted by the first UE to the second UE on a first set of resources in a dedicated resource pool for sidelink control signaling. The first UE may receive an indication that a second transmission is scheduled to be transmitted by the first UE on a second set of resources which at least partially overlaps in time with the first set of resources. The first UE may transmit at least one of the first transmission or the second transmission in accordance with a conflict resolution rule based on the second set of resources at least partially overlapping with the first set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a first wireless device may transmit sidelink control information to a second wireless device, which includes a first scheduling for an uplink transmission by a second wireless device during a first slot. The second wireless device may decode the sidelink control information to determine an operating mode of the first wireless device during the first slot, such as a transmitting mode or a receiving mode. Based on the operating mode, the second wireless device may drop or delay the uplink transmission. In some cases, the first wireless device may schedule an uplink transmission to be performed by the second wireless device during a second slot, and the first wireless device may switch from a transmitting mode to a receiving mode in order to receive the scheduled uplink transmission from the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may determine a set of resources for sidelink communication with one or more neighboring UEs. The transmitting UE may transmit multiple sidelink control messages to the neighboring UEs indicating the set of resources are reserved for a sidelink data message. The neighboring UEs may receive at least one of the sidelink control messages. A neighboring UE may determine a portion of the resources are reserved for a sidelink data message with the transmitting UE and may transmit or receive the sidelink data message using the portion of the resources. Additionally or alternatively, a neighboring UE may determine the resources are reserved for a sidelink data message between the transmitting UE and another neighboring UE and may select alternative resources for sidelink data messages to may avoid using the reserved resources.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support improved assignment techniques for dynamic group common physical control channels. In some cases, a user equipment (UE) may receive a control message via a group common control channel. The control message may be monitored by a plurality of UEs, and the control message may include one or more control information segments for a set of UEs of the plurality. The control message may include one or more integer values associated with respective control information segments and a prime number. The integer values and the prime number may be configured to address each UE of the set of UEs. The UE may process the prime number, the integer values, and an integer value that corresponds to an identifier (ID) of the UE to determine applicability of the control message to the UE.
